    Estrogen effects on postural balance in postmenopausal women without vasomotor symptoms: A randomized masked trial2000In: Obstetrics and Gynecology, ISSN 0029-7844, E-ISSN 1873-233X, Vol. 95, no 2, p. 278-283Article in journal (Refereed)
    Abstract [en]

    Objective: To assess whether estrogen treatment given to postmenopausal women without vasomotor symptoms improves balance more than placebo. Methods: Forty healthy postmenopausal women without vasomotor symptoms were randomized to transdermal 17▀-estradiol (E2) 50 ╡g/day for 14 weeks or identical transdermal placebo patches. Postural balance was measured with dynamic posturography before and after 4, 12, and 14 weeks of therapy. In this test, the visual, vestibular, and somatosensory systems were provoked with increasing difficulty and body sway was measured with a dual forceplate. A low score showed large sway and a score of 100 showed no sway at all. Results: Thirty-eight women completed the study. Both groups had normal balance for their ages and near maximum scores in the three easier balance tests at baseline. In the most difficult test, both groups improved their postural balance significantly (from 13 to 32 and from 22 to 39, respectively) after 4 weeks. Thereafter, no change was seen. One problem was low statistical power, but the relative change in balance did not differ between groups. The comparison did not show even a minute advantage of E2 over placebo, so a study with higher power would probably not have shown a more pronounced effect of estrogen than placebo. The change over time did not differ between groups, which indicates a significant learning effect.Conclusion: In women without vasomotor symptoms, estrogen therapy did not seem to increase postural balance significantly more than placebo. However, we could not rule out that estrogens affect postural balance in women with vasomotor symptoms. Copyright (C) 2000 The American College of Obstetricians and Gynecologists.

    SweDCIS: Radiotherapy after sector resection for ductal carcinoma in situ of the breast. Results of a randomised trial in a population offered mammography screening2006In: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 45, no 5, p. 536-543Article in journal (Refereed)
    Abstract [en]

    We studied the effect of postoperative radiotherapy (RT) after breast sector resection for ductal carcinoma in situ (DCIS). The study protocol stipulated radical surgery but microscopically clear margins were not mandatory. We randomised 1 046 operated women to postoperative RT or control between 1987 and 1999. The primary endpoint was ipsilateral local recurrence. Secondary endpoints were contralateral breast cancer, distant metastasis and death. After a median follow-up of 5.2 years (range 0.1-13.8) there were 44 recurrences in the RT group corresponding to a cumulative incidence of 0.07 (95% confidence interval (CI) 0.05-0.10). In the control group there were 117 recurrences giving a cumulative incidence of 0.22 (95% CI 0.18-0.26) giving an overall hazard ratio of 0.33 (95% CI 0.24-0.47, p <0.0001). Twenty two percent of the patients had microscopically unknown or involved margins. We found no evidence for different effects of RTon the relative risk of invasive or in situ recurrence. Secondary endpoints did not differ. Women undergoing sector resection for DCIS under conditions of population based screening mammography benefit from postoperative RT to the breast. Seven patients needed RT-treatment to prevent one recurrence. © 2006 Taylor & Francis.

    Clinicopathological significance of microsatellite instability and mutated RIZ in colorectal cancer2004In: Annals of Oncology, ISSN 0923-7534, E-ISSN 1569-8041, Vol. 15, no 2, p. 242-246Article in journal (Refereed)
    Abstract [en]

    Background: Several studies have shown that microsatellite instability (MSI) is related to favourable survival in colorectal cancer patients but there are controversial results. Tumour suppressor gene RIZ is a susceptible mutational target of MSI. However, its clinicopathological significance has not been investigated. We investigated the prognostic significance of MSI in Swedish colorectal cancer patients and the clinicopathological significance of RIZ mutations. Patients and methods: We analysed 438 colorectal adenocarcinomas for MSI by microsatellite analysis. Among them, 29 MSI and 28 microsatellite stable (MSS) tumours were examined for RIZ mutations by DNA sequencing. Results: MSI (13% of 438 cases) was not associated with survival (rate ratio=0.97, 95% confidence interval =0.57-1.64, P=0.90), although it was related to proximal tumour (P <0.001), poor differentiation and mucinous carcinomas (P <0.001), multiple tumours (P=0.01) and negative/weak expression of hMLH1 (P=0.03). RIZ mutations were detected in 31% of 29 MSI tumours but in none of the 28 MSS tumours. The mutations were related to female (P=0.01), proximal tumour (P=0.01), stage B (P=0.01) and poor differentiation (P=0.047). Conclusions: MSI was not a prognostic factor in the Swedish patients included in this study. Clinicopathological variables associated with RIZ mutations might be a consequence of the MSI characteristics.

    A phytobezoar in the acute abdomen2009In: American Journal of Surgery, ISSN 0002-9610, E-ISSN 1879-1883, Vol. 197, no 2, p. e21-e22Article in journal (Refereed)
    Abstract [en]

    A phytobezoar is a rare differential diagnosis in the acute abdomen. An 89-year-old woman presented with lower abdominal pain. A computed tomography scan and ultrasound suggested the presence of a bezoar. A phytobezoar was extracted surgically, and a resection was performed of the perforated small bowel segment. The etiology and management of phytobezoars are discussed.

    Urea Clearance: A New Technique Based on Microdialysis to Assess Liver Blood Flow Studied in a Pig Model of Ischemia/Reperfusion2010In: EUROPEAN SURGICAL RESEARCH, ISSN 0014-312X, Vol. 45, no 2, p. 105-112Article in journal (Refereed)
    Abstract [en]

    Delayed detection of ischemia is one of the most feared postoperative complications. Early detection of impaired blood flow and close monitoring of the organ-specific metabolic status may therefore be critical for the surgical outcome. Urea clearance is a new technique for continuous monitoring of alterations in blood flow and metabolic markers with acceptable temporal characteristics. We compare this new microdialysis technique with the established microdialysis ethanol technique to assess hepatic blood flow. Six pigs were used in a liver ischemia/reperfusion injury model. Microdialysis catheters were placed in liver segment IV and all circulation was stopped for 80 min, followed by reperfusion for 220 min. Urea and ethanol clearance was calculated from the dialysate and correlated with metabolic changes. A laser Doppler probe was used as reference of restoration of blood flow. Both urea and ethanol clearance reproducibly depicted changes in liver blood flow in relation to metabolic changes and laser Doppler measurements. The two techniques highly correlated both overall and during the reperfusion phase (r = 0.8) and the changes were paralleled by altered perfusion as recorded by laser Doppler.

    Long-term outcome is worse after laparoscopic than after conventional Nissen fundoplication2005In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 40, no 11, p. 1261-1268Article in journal (Refereed)
    Abstract [en]

    Objective. No long-term studies of laparoscopic and open fundoplication were available in 1994. The aim of this study was to compare reflux control and side effects after laparoscopic and open fundoplication. Material and methods. Adult patients with uncomplicated gastro-oesophageal reflux disease were included in this prospective randomized clinical trial between laparoscopic and open 360° fundoplication. Patients with uncomplicated gastro-oesophageal reflux disease were included with the exception of those with weak peristalsis or suspected short oesophagus. Two senior surgeons, well trained in laparoscopic antireflux surgery, performed the 45 laparoscopic operations. Forty-eight patients underwent open surgery performed or supervised by two other senior surgeons, also well trained in gastro-oesophageal surgery. One of the latter recruited all the patients. Manometry and 24-h oesophageal pH monitoring were performed before operation and 6 months postoperatively. Manometry also included a short-term reflux test, an acid clearing test and an acid perfusion test. Symptom evaluation was performed before surgery, 6 moths after and at long-term follow-up (33-79 months postoperatively) by the same surgeon. Long-term follow-up also included endoscopy. Results. Six months after laparoscopy 4 patients had disabling dysphagia. None of the patient had disabling dysphagia after laparotomy. Four patients had mild heartburn 6 months after laparoscopy and 2 patients after laparotomy. Between 6 months' follow-up and long-term follow-up, 6 patients were reoperated on in the laparoscopy group and 2 patients in the laparotomy group. Three patients operated on with laparotomy had died of intercurrent diseases. After laparoscopy, at long-term follow-up, 62% of patients (28/45) were satisfied compared with 91% (41/45) after laparotomy. The difference was significant (p < 0.01). Conclusions. Early postoperative reflux control was similar for laparoscopic and conventional fundoplication. At long-term follow-up significantly more patients were satisfied after laparotomy than after laparoscopy. © 2005 Taylor & Francis.

    Consequences of axillary recurrence after conservative breast surgery2002In: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 89, no 7, p. 902-908Article in journal (Refereed)
    Abstract [en]

    Background: The aim was to study the incidence, time course and prognosis of patients who developed axillary recurrence after breast-conserving surgery, and to evaluate possible risk factors for axillary recurrence and prognostic factors after axillary recurrence. Methods: In a population-based cohort of 6613 women with invasive breast cancer who had breast-conserving surgery between 1981 and 1990, 92 recurrences in the ipsilateral axilla were identified. Risk factors for axillary recurrence were studied in a case-control study nested in the cohort, and late survival was documented in the women with axillary recurrence. Results: The overall risk of axillary recurrence was 1.0 per cent at 5 years and 1.7 per cent at 10 years. The risk of axillary recurrence increased with tumour size (P = 0.033) and was highest in younger women (odds ratio (OR) 3.9 for women aged less than 40 years compared with those aged 50-59 years). Radiotherapy to the breast reduced the risk of axillary recurrence (OR 0.1 (95 per cent confidence interval 0.1 to 0.4)). The breast cancer-specific survival rate after axillary recurrence, as measured from primary treatment, was 78.0 per cent at 5 years and 52.3 per cent at 10 years. Tumour size and node status had a statistically significant effect on death from breast cancer. Conclusion: Axillary recurrence is rare, although more common in younger women with large tumours. Radiotherapy to the breast was protective. Tumour size and node status were the most important prognostic factors in women with axillary recurrence.

    Local recurrence in the breast after conservative surgery - A study of prognosis and prognostic factors in 391 women2002In: European Journal of Cancer, ISSN 0959-8049, E-ISSN 1879-0852, Vol. 38, no 14, p. 1860-1870Article in journal (Refereed)
    Abstract [en]

    In a population-based cohort of 6613 women with invasive breast cancer, who had breast-conserving surgery between 1981 and 1990, 391 recurrences in the operated breast were identified. The main aim of this study was to examine the prognosis and prognostic factors in different subgroups of local recurrences, characterised by the time to recurrence, location of recurrence and previously given radiotherapy. The median follow-up for women who had a local recurrence was 7.9 years. The life-table estimates for breast cancer-specific survival in women with local recurrences were 84.5% (standard error (S.E.) 1.8) at 5 years and 70.9% (S.E. 2.7) at 10 years. The risk of breast cancer death was highest among women who had an early (=2 years) recurrence in the same quadrant as the primary tumour, with a breast cancer-specific survival of 67.9% (S.E. 4.8) at 5 years and 56.0% (S.E. 5.9) at 10 years. There was a statistically significant difference in the probability of breast cancer-specific survival, as measured from the recurrence, between women who initially did or did not receive radiotherapy (P=0.0123). However, when measured from primary treatment, there was no significant difference, indicating that the difference in prognosis could be due to a lead-time bias. Independent prognostic factors for breast cancer-specific survival in women with local recurrences were time to local recurrence and the Nottingham Prognostic Index (NPI). ⌐ 2002 Elsevier Science Ltd.

    Risk factors for local recurrence after breast-conserving surgery2003In: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 90, no 9, p. 1093-1102Article in journal (Refereed)
    Abstract [en]

    Background: It is not clear whether risk factors for local recurrence after breast-conserving surgery differ in women having surgery for in situ or invasive cancer. Furthermore, the Nottingham Prognostic Index (NPI) and Nottingham Histological Grade (NHG) have been little studied as determinants of local recurrence risk. Method: In a case-control study (491 cases and 1098 controls) nested within a cohort of 7502 women who had surgery for in situ or invasive cancer of the breast, patient characteristics, tumour characteristics and treatment-related variables were evaluated as risk factors for local recurrence. Results: Multivariate conditional logistic regression analyses showed that age below 40 years, tumour multicentricity and an unclear or unknown surgical margin were significant risk factors for local recurrence. Radiotherapy to the breast and adjuvant hormone therapy were protective. Cancer in situ was not associated with a higher risk of local recurrence than invasive cancer (odds ratio 1.0, 95 per cent confidence interval 0.8 to 1.3). NHG and NPI were not helpful in determining risk of local recurrence. Conclusion: Margin status, age, tumour multicentricity, and use of radiotherapy and adjuvant hormone therapy were important determinants of risk of local recurrence. With the exception of surgical margin, variables related to the quality of surgical management did not predict risk of local recurrence.

    Long-term follow-up of acupuncture and hormone therapy on hot flushes in women with breast cancer: a prospective, randomized, controlled multicenter trial2008In: Climacteric, ISSN 1369-7137, E-ISSN 1473-0804, Vol. 11, no 2, p. 166-174Article in journal (Refereed)
    Abstract [en]

    Objective: To evaluate the effects of electro-acupuncture (EA) and hormone therapy (HT) on vasomotor symptoms in women with a history of breast cancer.

    Methods: Forty-five women were randomized to EA (n = 27) for 12 weeks or HT (n = 18) for 24 months. The number of and distress caused by hot flushes were registered daily before, during and up to 24 months after start of treatment.

    Results: In 19 women who completed 12 weeks of EA, the median number of hot flushes/24 h decreased from 9.6 (interquartile range (IQR) 6.6-9.9) at baseline to 4.3 (IQR 1.0-7.1) at 12 weeks of treatment (p < 0.001). At 12 months after start of treatment, 14 women with only the initial 12 weeks of EA had a median number of flushes/24 h of 4.9 (IQR 1.8-7.3), and at 24 months seven women with no other treatment than EA had 2.1 (IQR 1.6-2.8) flushes/24 h. Another five women had a decreased number of flushes after having additional EA. The 18 women with HT had a baseline median number of flushes/24 h of 6.6 (IQR 4.0-8.9), and 0.0 (IQR 0.0-1.6; p = 0.001) at 12 weeks.

    Conclusion: Electro-acupuncture is a possible treatment of vasomotor symptoms for women with breast cancer and should be further studied for this group of women.

    MANBA polymorphism was related to increased risk of colorectal cancer in Swedish but not in Chinese populations2008In: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 47, no 3, p. 372-378Article in journal (Refereed)
    Abstract [en]

    β-mannosidase, encoded by MANBA, has been suggested to be implicated in cancers, while genetic variations in the MANBA in relation to colorectal cancer (CRC) risk has not been examined. In this study, we investigated the relationship of a polymorphic CA repeat in MANBA gene with CRC risk in 152 Swedish CRC patients and 441 Swedish controls, and 196 Chinese CRC patients and 577 Chinese controls, as well as the clinicopathologic significance of this polymorphism on CRC patients, by using capillary electrophoresis. The MANBA genotypes were related to CRC risk in the Swedish population (p=0.03), but not in the Chinese population. In the Swedish population, individuals with < 22 CAs/> 22 CAs had significantly increased risk for CRC compared with those with ≥22 CAs/≥ 22 CAs (gender-age-adjusted analysis: OR 1.93, 95% CI 1.06-3.51). There was no relationship between the polymorphism and clinicopathologic variables. These findings suggest the different susceptibilities of this polymorphism to CRC development in the two populations. © 2008 Taylor & Francis.

    Stromal staining for PINCH is an independent prognostic indicator in colorectal cancer2004In: Neoplasia, ISSN 1522-8002, Vol. 6, no 6, p. 796-801Article in journal (Refereed)
    Abstract [en]

    Particularly interesting new cysteine-histidine-rich protein (PINCH), a LIM domain adapter protein that functions in the integrin and growth factor signal transduction pathway, is upregulated in stroma associated with many common cancers. The finding suggested that PINCH may be involved in promoting tumor-stromal interactions that support tumor progression, and, if so, tumors with abundant PINCH stromal staining may have a worse prognosis. To test this hypothesis, 174 primary colorectal adenocarcinomas with 39 distant normal mucosa samples and 26 metastases in the lymph nodes were studied by immunohistochemistry, and 7 additional colon tumors were studied by Western blot analysis and immunofluorescence. The abundance of PINCH protein in stroma increased from normal mucosa to primary tumor to metastasis (P < .05), and was more intense at the invasive margin than it was in the intratumoral stroma. Strong stromal immunostaining for PINCH was shown to predict a worse outcome (rate ratio 2.1, 95% CI 1.16-3.37, P = .01), independent of Dukes stage, growth pattern, and tumor differentiation. PINCH was detected in fibroblasts, myofibroblasts, and a proportion of endothelial cells of the tumor vasculature, supporting the involvement of PINCH in promoting tumor-stromal interactions that support tumor progression. Interestingly, stromal staining for PINCH was an independent prognostic indicator in colorectal cancer.

    Clinical and biological significance of angiogenesis and lymphangiogenesis in colorectal cancer2009In: DIGESTIVE AND LIVER DISEASE, ISSN 1590-8658, Vol. 41, no 2, p. 116-122Article in journal (Refereed)
    Abstract [en]

    Purpose. The aim of this study was to get a deeper understanding into how adults with cerebral palsy (CP) experience physiotherapy and physical activity in a perspective from childhood to adulthood; and how personal and environmental factors influence possibilities for physiotherapy and physical activity. Method. Data was collected through interviews with 22 community-living adults (35-68 years) with CP, from five counties in Sweden. The questions were open-ended and the interviews were taped and transcribed to written language. The material was analysed through qualitative content analysis, a classification process resulting in different themes. Results. The narratives from the 22 informants, based on experiences from childhood to adulthood, resulted in a description of prerequisites for carrying out physiotherapy and physical activity. Five different themes were identified: (i) Being enjoyable, (ii) Giving effects, (iii) Being comprehensible, (iv) Being integrated in daily life, and (v) Supportive healthcare with competent professionals. Conclusion. The information from the interviews elucidates the importance of a lifelong support from healthcare professionals. Physiotherapists with attentiveness to different life situations in combination with good understanding and knowledge in CP could facilitate continuous physical activity in people growing up and ageing with CP.

    Association of NFKBIA polymorphism with colorectal cancer risk and prognosis in Swedish and Chinese populations2007In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 42, no 3, p. 345-350Article in journal (Refereed)
    Abstract [en]

    Objective. The inhibitory proteins, IκBs, regulate the activity of nuclear factor kappa-beta (NF-κB), which is implicated in tumorigenesis by regulating expression of a variety of genes involved in cellular transformation, proliferation, invasion, angiogenesis and metastasis. Variants in the genes encoding IκBs may be involved in cancer development through the activation of NF-κB. The objective of this study was to investigate the susceptibility of an A to G variation (rs696) in the 3′ UTR of NFKBIA (encoding IκBα) to colorectal cancer (CRC) and the association of this polymorphism with clinicopathologic variables in CRC patients. Material and methods. A case-control study was carried out on a Swedish (155 CRCs, 438 controls) and a Chinese population (199 CRCs, 577 controls). The genotype of NFKBIA was determined by PCR-restriction fragment length polymorphism. Results. The frequency of the AG genotype was increased in the Chinese patients ≥50 years of age compared with the Chinese controls (odds ratio (OR) = 3.06, 95% confidence interval (CI) = 1.55-6.02, p=0.001), even when adjusted for age (OR = 3.20, 95% CI = 1.61-6.38, p=0.001). The GG genotype of NFKBIA was related to a poorer survival rate in the Swedish patients, independent of gender, age, tumour location, Dukes' stage and differentiation (hazard ratio = 3.10, 95% Cl = 1.28-7.60, p=0.01). Conclusions. Chinese individuals ≥50 years of age carrying the AG genotype of NFKBIA may be at an increased risk of developing CRC, and the GG genotype of NFKBIA may be considered as a prognostic factor for Swedish CRC patients. © 2007 Taylor & Francis.

    Release of Satiety Hormones in Response to Specific Dietary Proteins Is Different between Human and Murine Small Intestinal Mucosa2010In: Annals of Nutrition and Metabolism, ISSN 0250-6807, E-ISSN 1421-9697, Vol. 56, no 4, p. 308-313Article in journal (Refereed)
    Abstract [en]

    Background/Aim: High protein diets are the most effective to stimulate cholecystokinin (CCK) and glucagon-like peptide 1 (GLP-1) release; however, which proteins are the most potent is not known. Here, the effects of specific dietary proteins on intestinal CCK and GLP-1 release were examined. Methods: Duodenal biopsies of 10 healthy male subjects and 10 male rats were taken and placed in an Ussing chamber system. The biopsies were exposed on the luminal side to buffer, egg protein, codfish protein, ovomucoid, pea protein, and wheat protein. After an exposure time of 2 h, samples were taken from the serosal side. Results: Pea protein and wheat protein increased CCK and GLP-1 release in human duodenal tissue, while codfish protein only increased CCK release. No elevated levels of CCK and GLP-1 were found after exposure of rat tissue to different proteins. Conclusion: Pea and wheat protein are the most potent stimulators of CCK and GLP-1 release in human duodenal tissue, and may therefore be good dietary additives in weight management.

    Outcome After Haemorrhoidopexy2008Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: This dissertation is composed of five individual studies of the stapled haemorrhoidopexy operation. The operation was launched to an international audience in 1998 by the Italian surgeon Antonio Longo. In conventional surgery the prolapsed piles are excised from the anodermal part of the prolapse up through the anal canal into the lower rectal mucosa where the pile is divided with diathermy or suture ligated and excised. It leaves open wounds throughout the anal canal. These wounds can be very painful, especially at defecation, and will take from three to six weeks to heal. In the stapled haemorrhoidopexy operation symptomatic haemorrhoids are seen as a disease of anodermal, haemorrhoidal and rectal mucosal prolapse of varying degree. The main component of the prolapse is the redundancy of rectal mucosa. By pushing back the prolapse into the anal canal followed by excision of the mucosal redundancy above the anal canal with a circular stapler devise a mucosal anastomosis is fashioned. This anastomosis is situated immediately above the haemorrhoids and will attach them to the rectal muscular wall to prevent further prolapse. The operation is associated with substantially less pain and a quicker recovery.

    Methods: For the five studies, a total of 334 patients were operated for haemorrhoidal prolapse. The first operations were performed in February 1998. All patients were assessed preoperatively and postoperatively with the same set of protocols as follows. The symptoms of haemorrhoids were scored with a questionnaire to patients to obtain their independent statements of the frequency of each of five cardinal symptoms: pain, bleeding, pruritus, soiling and prolapse in need of manual reduction. A diary was used by patients to report daily pain scores, use of pain medication and speed of recovery within the first 14 postoperative days. The surgeon rated the deranged anal anatomy before and after surgery. We also developed an algorithm based on the patients’ statement of digital reduction of prolapse (grade 3) and the surgeon’s assessment of lesser prolapse at proctoscopy (grade 2). Absence of prolapse was grade 1. The surgeon also provided statements about the conduct of the operation and rated the technical complexity. The information, for all patients, was entered into an electronic data base.

    Results: One registry based study and one prospective randomised controlled trial assessed the advantage of performing the operation under perianal local anaesthetic block. The postoperative pain and surgical outcome was independent of the type of anaesthesia. No operation under local block had to be converted to general anaesthesia. Anodermal prolapse is seen in 70 percent of the patients. In a registry-based study we found that excision of the anodermal folds did not increase the postoperative pain provided the excision stopped at the anal verge. In 270 patients with precise preoperative and postoperative classification we found that the symptomatic load was identical for grades 2 and 3. The symptoms were independent of the anodermal prolapse. The symptoms were greatly reduced when the operation turned out grade 1 prolapse. The long-term result was assessed in 153 patients operated 1 year to 6 years previously. The need for early re-intervention was 6.2 percent representing technical error to reduce the prolapse. At the final evaluation 12 patients (8.2 percent) complained of a mucoanal prolapse in need of digital reduction. The mean symptom burden had been reduced from 8.1 to 2.5 points but 17 percent had at least one cardinal symptom with a weekly frequency.

    Conclusions: Stapled haemorrhoidopexy should be performed as day surgery under local anaesthesia. Any remaining anodermal prolapse should be excised. The optimal long-term outcome is grade 1A or 1B with low symptom score. There was an 87 percent chance of cure of the prolapse with the first haemorrhoidopexy. About half the failures were insufficient primary surgery and half a relapse of the prolapse.

    Abstract [en]

    Purpose This study was designed to demonstrate the usefulness of a method of regional anesthesia for circular stapler anopexy for prolapsing hemorrhoids.

    Methods Thirty-three patients consented to stapled anopexy under perianal local anesthesia. Eighteen patients with stapled anopexy under general anesthesia were controls. The perianal block was applied with 40 ml of ropivacaine, 4.75 mg/ml, injected immediately peripheral to the external sphincter. A submucosal block with 15 ml of ropivacaine, 2 mg/ml, was added after applying the pursestring suture. Postoperative pain was rated by the patient for 14 days by using a ten-point visual analogue scale. Patients also submitted a preoperative and postoperative (3–6 months) symptom questionnaire to rate anal symptoms.

    Results No operation was converted to general anesthesia. Operation time was similar in both groups. All patients in the local anesthesia group were pain free at discharge. The sums of pain scores during 14 days for daily average pain and peak pain were similar in both groups (average pain 23 (local anesthesia) vs. 35 (general anesthesia); peak pain 39 (local anesthesia) vs. 50 (general anesthesia); P > 0.05). The preoperative symptom scores were 7.8 (local anesthesia) vs. 8.9 (general anesthesia) points, and the follow-up scores were 2.2 (local anesthesia) and 2.7 (general anesthesia), a significant improvement (P = 0.001) in both groups but not different between groups.

    Conclusions A perianal local block is easy to apply and has a high degree of acceptance among patients. The operation time, postoperative pain, and success rates of the operation equaled those of stapled anopexy performed under general anesthesia. The advantages are quicker turnover between cases and simpler management of pain-free postoperative patients in day surgery.

    Abstract [en]

    Background: The aim was to assess the feasibility of performing stapled haemorrhoidopexy under local anaesthesia.

    Methods: Fifty-eight patients with haemorrhoid prolapse were randomized to receive local or general anaesthesia. The perianal block was applied immediately peripheral to the external sphincter. Submucosal block was added after applying the purse-string suture. Patients reported average and peak pain daily for 14 days using a visual analogue scale (VAS). They also completed anal symptom questionnaires before the operation and at follow-up. The surgeon assessed the restoration of the anal anatomy 3-6 months after surgery.

    Results: The anal block was sufficient in all patients. The mean accumulated VAS score for average pain was 23·1 in the general anaesthesia group and 29·4 in the local anaesthesia group (P = 0·376); mean peak pain scores were 42·1 and 47·9 respectively (P = 0·537). Mean change in symptom load was also similar between the groups, with score differences of 7·0 in the general anaesthesia group and 6·1 in the local anaesthesia group. No patient had a recurrence of prolapse.

    Conclusion: Perianal local block is easy to apply with a high degree of acceptability among patients. Postoperative pain, restoration of anatomy and symptom resolution were similar to that of stapled haemorrhoidopexy performed under general anaesthesia.

    2007 (English)In: Colorectal Disease, ISSN 1462-8910, Vol. 9, no 8, p. 754-757Article in journal (Refereed) Published
    Abstract [en]

    Objective: We studied whether excision of residual external skin tags causes additional pain in patients undergoing a stapled anopexy for muco-anal prolapse.

    Method: Seventeen patients in whom skin tags had been excised were compared with 24 patients having no excision. The patients were selected from a prospective database of haemorrhoid surgery if they had submitted a diary with self-reported postoperative pain scores as well as a self-reported symptom questionnaire preoperatively and postoperatively. The tags were excised with preservation of the subdermal fascia.

    Results: There were 41 patients who fulfilled the criteria for inclusion. Seventeen (group 1) had tags excised and 24 (group 2) did not. Fifty-nine per cent in group 1 and 67% in group 2 experienced preoperative prolapse needing manual reposition. The mean height of the staple line was 2 cm above the dentate line in both groups. Daily average postoperative pain recorded as the sum of a self-reported VAS rating over 14 days was 26 points in both groups. The peak pain experienced was 42 and 43 points respectively (not significant). Resolution of postoperative pain over 14 days was identical. The preoperative and postoperative symptom score was comparable in both groups.

    Conclusion: Excision of anal skin tags should be carried out at the time of stapled anopexy.

    Abstract [en]

    Purpose: Haemorrhoid prolapse is an indication for surgery. A correlation between worsening anatomy and increasing symptoms is commonly assumed. We developed a classification algorithm of prolapse and external component, and evaluated its correlation to symptoms before and after surgery.

    Method: A study population comprising 180 patients operated for haemorrhoids in a multicentre randomized trial plus a validation set comprising 90 patients operated by us. The classification used three items: (i) patient self-report of prolapse requiring manual reposition; (ii) surgeon assessment of prolapse when patient negated manual reposition; (iii) surgeon assessment of external component. Patient self-reported were rated by frequency (never, 0 points; monthly, 1 point; weekly, 2 points and daily, 3 points). The algorithm yielded three grades: 1, no prolapse; 2, spontaneously reducing prolapse and 3, prolapse needing manual repositioning. The degree of external component was affixed as A, none; B, one or few tags and C, circumferential.

    Results: Anatomical grades did not differ between the two sets of patients before or after surgery. Preoperatively, 69% had grade 3 prolapse. Postoperatively, 89% were classified as grades 1A or B. The symptom load was similar for grades 2 and 3; mean 6.5 points preoperatively and 1.8 points postoperatively.

    Conclusion: This anatomical classification, based on strict criteria, reliably staged the haemorrhoid prolapse. There was no unique preoperative symptom profile associated with any degree of prolapse with or without an external component. Restored anal anatomy relieved symptoms. The classification also defined recurrence of haemorrhoids.

    Dual-Energy Computed Tomography Localizes Ectopic Parathyroid Adenoma2010In: The Journal of Clinical Endocrinology & Metabolism, ISSN 0021-972X, Vol. 95, no 7, p. 3092-3093Article in journal (Refereed)
    Abstract [en]

    Dual-energy computed tomography (DECT) can acquire two datasets showing different attenuation levels allowing collectionof additional information about the elementary chemical compositionof the scanned material. Color can then be assigned accordingto the 80- and 140-kV computed tomography (CT) values to obtaina color-mapped, dual-energy image. DECT has been used extensivelyin our department in postmortem CT with excellent results (1).One of the advantages of DECT is that iodine contrast uptakein soft tissue can be quantified. We were wondering about itsability to localize parathyroid adenomas (PAs).

    The effects of oral estriol on the endometrium in postmenopausal women2002In: Maturitas, ISSN 0378-5122, E-ISSN 1873-4111, Vol. 42, no 2, p. 149-156Article in journal (Refereed)
    Abstract [en]

    Objectives: To study the long-term effects of oral estriol tablets on the endometrium of postmenopausal women by TVS and histology. Method: This was a cross sectional, parallel-group, multicenter trial of 241 postmenopausal women, out of whom 125 were treated with oral estriol and 116 were untreated controls. Endometrial histology using Pipelle biopsies and/or dilatation and curettage (D&C) was taken, endometrial thickness was assessed by use of transvaginal ultrasound (TVS), and the relation between endometrial thickness and histology was calculated. Results: No statistically significant differences between the two groups were found in endometrial histology. There were found more polyps in the oral estriol group (14.0%) as compared with the control group (2.9%). The mean endometrial thickness in the oral estriol group was 3.0 mm compared with a mean value of 2.4 mm in the control group: P=0.01. Conclusions: No clinically relevant difference was found between the endometrium status (assessed by histology and TVS) of postmenopausal women on long-term oral estriol therapy and untreated controls. This trial supports the endometrial safety of maintenance treatment with oral estriol tablets. However, there are signs, not statistically significant, that may be associated with more endometrial polyps in postmenopausal women than if therapy is not given and that TVS is a useful instrument for the diagnosis. ⌐ 2002 Elsevier Science Ireland Ltd.

    Identification of cell adhesion molecules in the human follicle-associated epithelium that improve nanoparticle uptake into the Peyer's patches2006In: Journal of Pharmacology and Experimental Therapeutics, ISSN 0022-3565, E-ISSN 1521-0103, Vol. 319, no 2, p. 632-639Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to identify cell adhesion molecules that could serve as targets of the human follicle-associated epithelium (FAE) overlying Peyer's patches and to assess nanoparticle uptake levels across this epithelium. We first studied the expression of the mouse M-cell marker β1- integrin and used a model of human FAE derived from intestinal epithelial Caco-2 cells and Raji B-cells to identify additional potential targets by cDNA array. The protein expression of potential targets in the model FAE and in human ileal FAE tissues was quantified by immunofluorescence. Integrin targeting was studied by investigating the transport of Arg-Gly-Asp (RGD)-coated (integrin-binding), Arg-Gly-Glu (RGE)-coated (nonintegrin-binding), and uncoated nanoparticles across ileal specimens mounted in Ussing chambers. Both β1- integrin and the cell adhesion molecule CD9 were more abundantly expressed in the model and human FAE compared with the Caco-2 control cells or villus epithelium (VE). Uncoated nanoparticles were not taken up across either FAE or VE. General integrin targeting with RGD improved the nanoparticle transport dramatically across the FAE and to a lower extent across the VE. Compared with RGE, RGD improved transport 4-fold across the FAE. There was no difference in the transport of RGD- and RGE-coated nanoparticles across the VE. In conclusion, β1-integrin and CD9 were identified as targets in human FAE. The difference in RGD- and RGE-mediated transport across the FAE, but not the VE, suggests that a specific integrin interaction was the dominating mechanism for improved nanoparticle uptake across the FAE., whereas charge interaction contributed substantially to the improved VE uptake.

    Peyer's patches and M cells as potential sites of the inflammatory onset in Crohn's disease2006In: Annals of the New York Academy of Sciences, ISSN 0077-8923, E-ISSN 1749-6632, Vol. 1072, p. 218-232Article in journal (Refereed)
    Abstract [en]

    Clinical observations suggest that the sites of initial inflammation in ileal Crohn's disease (CD) are the lymphoid follicles, where the aphtoid lesions originate from small erosions of the follicle-associated epithelium (FAE). Lymphoid follicles and Peyer's patches (PPs) consist of a number of B-cell follicles with intervening T cell areas. The T cell follicular area is also populated by dendritic cells (DCs) and macrophages. A single layer of epithelial cells covering each follicle forms a dome between the surrounding villi. This FAE differs from normal villus epithelium in several ways that make the epithelial cells of the FAE more exposed to the luminal contents, more accessible to antigens, and in closer contact with the immune system. The most prominent feature is the presence of specialized M cells, which are optimized for antigen adherence and transport. M cells play an important role in the surveillance of the intestinal lumen, but also provide a route of entry for various pathogens. In this article we review the current knowledge on the epithelial phenotype of the human FAE, and changes of the FAE and M cells in intestinal inflammation, leading to a hypothesis of the role of the FAE and M cells in the pathogenesis of CD.

    CDC73/HRPT2 CpG island hypermethylation and mutation of 5 -untranslated sequence are uncommon mechanisms of silencing parafibromin in parathyroid tumors2010In: ENDOCRINE-RELATED CANCER, ISSN 1351-0088, Vol. 17, no 1, p. 273-282Article in journal (Refereed)
    Abstract [en]

    The tumor suppressor HRPT2/CDC73 is mutated in constitutive DNA from patients with the familial disorder hyperparathyroidism-jaw tumor syndrome and in similar to 70% of all parathyroid carcinomas. In a number of HRPT2 mutant tumors however, expression of the encoded protein parafibromin is lost in the absence of a clear second event such as HRPT2 allelic loss or the presence of a second mutation in this tumor suppressor gene. We sought to determine whether hypermethylation of a 713 bp CpG island extending 648 nucleotides upstream of the HRPT2 translational start site and 65 nucleotides into exon 1 might be a mechanism contributing to the loss of expression of parafibromin in parathyroid tumors. Furthermore, we asked whether mutations might be present in the 5-untranslated region (5-UTR) of HRPT2. We investigated a pool of tissue from 3 normal parathyroid glands, as well as 15 individual parathyroid tumor samples including 6 tumors with known HRPT2 mutations, for hypermethylation of the HRPT2 CpG island. Methylation was not identified in any specimens despite complete loss of parafibromin expression in two parathyroid carcinomas with a single detectable HRPT2 mutation and retention of the wild-type HRPT2 allele. Furthermore, no mutations of a likely pathogenic nature were identified in the 5-UTR of HRPT2. These data strongly suggest that alternative mechanisms such as mutation in HRPT2 intronic regions, additional epigenetic regulation such as histone modifications, or other regulatory inactivation mechanisms such as targeting by microRNAs may play a role in the loss of parafibromin expression.

    Safety of the temporary loop ileostomy2002In: Colorectal Disease, ISSN 1462-8910, E-ISSN 1463-1318, Vol. 4, no 5, p. 361-364Article in journal (Refereed)
    Abstract [en]

    Objective. To evaluate the complications of the temporary loop ileostomy. Method. A retrospective study of 222 consecutive patients with low anterior resection, ileal pouch-anal anastomosis or continent ileostomy and a diverting loop ileostomy routinely fashioned during the primary operation. The loop ileostomy was closed in 213 patients (96%) during the minimum follow-up period of 15 months. Results. Four patients (2%) required preterm closure of the ostomy due to stomal retraction (n = 3) or bowel obstruction (n = 1). Four patients were readmitted due to transient bowel obstruction that resolved without surgery. After closure of the loop ileostomy a total of 27 patients (13%) had complications. In 7 patients emergency re-operation was done due to small bowel obstruction (n = 5) or intra-abdominal abscess (n = 2). Elective re-operation was done in 5 patients for hernia at the site of the previous stoma. Despite the use of a loop ileostomy there was 1 postoperative death after the initial operation in consequence of anastomotic leakage. There was 1 death in consequence of closure of the loop ileostomy after 3 weeks due to intra-abdominal sepsis and heart failure. Conclusion. In this series closure of the ostomy was associated with one death (0.5%) and overall ostomy-related morbidity included the need to re-operate in 6%.

    Gallstone disease: Population based studies on risk factors, symptomatology and complications2008Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background & aims: Gallstone disease is common, costly and its complications are sometimes life threatening. The aim of this thesis is to determine the prevalence and incidence in relation to putative risk factors in the general population. Furthermore, to identify individuals with asymptomatic gallstones who are at risk of developing complications and, finally, to identify those who are at risk of an unsatisfactory outcome after cholecystectomy.

    Material & methods: A sample of the adult (35-85 y.) general population was screened with ultrasound examination, blood tests and a questionnaire regarding digestive symptoms, life-style and quality of life. After excluding 115 subjects, who previously had a cholecystectomy, 739 participated. The examination was repeated after a minimum of five years. The individuals who were shown to have gallstones were followed in order to identify risk factors for developing complications. 200 consecutive symptomatic patients were operated with cholecystectomy on defined indications. They completed a questionnaire regarding digestive symptoms, life-style and quality of life before and three and twelve months after surgery.

    Results: The crude prevalence of gallstone disease was 17.2 % for women and 12.4% for men. It increased with age and was higher among women. Symptoms did not differ between subjects with and without gallstones, but those previously operated with cholecystectomy did worse both regarding symptoms and quality of life. The estimated crude annual gallstone incidence was 1.5%. This increased with age, but did not differ between the sexes. Gallstone development was positively related to elevated blood lipids and negatively related to alcohol consumption. Fourteen of 120 subjects with gallstones at the primary screening developed a complication demanding treatment during a follow-up interval of 87 (3-146) months. In the patient series operated on strict indications, 91.3 % of those who had reported typical gallstone related pain preoperatively, experienced total or partial pain relief 3 months postoperatively. With atypical pain preoperatively, the corresponding figure was 77.1 %. The findings 12 months postoperatively were similar. In the logistic regression analysis, young age, frequency of pain episodes, atypical pain, specific food intolerance and disturbing abdominal gas were positively related to the frequency of abdominal pain 12 months after surgery.

    Conclusion: The prevalence of gallstones was positively related to age and female gender. Previous cholecystectomy was associated with more symptoms and worse quality of life. The annual gallstone incidence of 1.5 % was high in comparison with other studies, but our population was older. In general, neither prevalent nor incident gallstones in the general population were associated with specific symptoms. The cumulative risk of developing a complication to gallstone disease during a 5-year followup interval was 7.6 % with no tendency to level off.

    Patients with typical pain had a better outcome after cholecystectomy. Young age, atypical pain and frequent pain episodes before surgery were major risk factors for a worse outcome in terms of persistent pain.

    Abstract [en]

    Background: There are only a few Swedish studies on the prevalence of gallstone disease in selected age groups, and none including possible risk factors. Methods: Of a population sample of 1200 individuals (age, 35-85 years), 857 participated in the study. The study subjects were asked to answer a questionnaire about potential risk factors (occupation, childbirth, life style, and so forth), symptoms, and quality of life. Cholecystectomy had previously been done in 115 subjects, leaving 742 for ultrasound examination of the gallbladder. Results: The prevalence of gallstone disease increased with age, and at 75 years or more, 53% of the women and 32% of the men either had gallstones or had previously undergone cholecystectomy (32% and 13%, respectively). When comparing subjects with and without gallstones, there were no differences with regard to any variable, including blood lipid levels. The odds ratio of previous cholecystectomy was increased in subjects with an occupation requiring no specific education and reduced in subjects using wine or spirits every week. The odds ratio of abdominal pain was increased after previous cholecystectomy. Women in this group also experienced a lower quality of life. Conclusions: The age and sex distribution of gallstone disease was in the order of the magnitude seen in other Scandinavian countries. None of the studied variables differed between subjects with and without gallstones. Subjects previously operated on with cholecystectomy did worse with regard to symptoms and quality of life.

    Background: Gallbladder stones are common in the developed world. Complications of gallstones contribute substantially to healthcare costs and may be life threatening. The identification of individuals likely to develop complications would be of benefit in clinical practice as elective cholecystectomy could then be performed.

    Methods: Seven hundred and thirty-nine subjects aged 35-85 years from the general population were screened for gallbladder problems by ultrasonography and questionnaire assessment of putative risk factors and digestive symptoms. Gallstones, cholesterolosis or sludge in the gallbladder were diagnosed in 123 (16·3 per cent) of 739 subjects, 120 of whom were followed for a median of 87 (range 3-146) months to May 2003 or until treatment was required.

    Results: Fourteen patients were admitted to hospital and treated for gallstone-related complications or symptoms. The cumulative risk of being treated during the first 5 years after detection of asymptomatic gallstones was 7·6 per cent and there was no indication of this risk levelling off. There were no significant differences between treated and untreated subjects with regard to digestive symptoms or any of the risk factors monitored at the initial screening, although treated subjects were significantly younger than those who were not treated.

    Conclusion: Nearly one in ten individuals with asymptomatic gallbladder stones in the general population may be expected to develop symptoms or complications that require treatment within 5 years. Age may be inversely related to the incidence of complications.

    Background: This study examined symptomatology and quality of life following elective cholecystectomy for symptomatic gallstone disease with defined indications for surgery.

    Methods: In this prospective study of 200 consecutive patients (161 women; median age 46·5 (range 24-79) years), strict indications for elective cholecystectomy were stipulated. Digestive symptoms and quality of life were recorded with a self-administered questionnaire before and at 3 and 12 months after surgery.

    Results: Of 149 patients who experienced abdominal pain with typical location before surgery, 136 (91·3 per cent) reported total remission or reduced frequency of that type of pain 12 months later. Of 35 patients who reported atypical or multiple pain location before operation, 27 (77 per cent) experienced reduced frequency or disappearance of that type of pain. Frequency of pain episodes, atypical or multiple pain location, specific food intolerance and frequency of disturbing abdominal gas at baseline correlated positively with the frequency of abdominal pain episodes at 12 months after surgery. There was a tendency towards an inverse relation to age.

    Conclusion: The frequency of persistent abdominal pain after elective cholecystectomy was low among patients with typical pain location before surgery. Atypical pain location, and frequent pain episodes before operation significantly reduced the chance of becoming pain-free.

    Incidence of and potential risk factors for gallstone disease in a general population sample2009In: BRITISH JOURNAL OF SURGERY, ISSN 0007-1323, Vol. 96, no 11, p. 1315-1322Article in journal (Refereed)
    Abstract [en]

    Background: Several epidemiological studies have been published, but there are few reports on relations between gallstone incidence, symptomatology and risk factors. Methods: Of 621 randomly selected individuals aged 35-85 years in a general population who been screened previously, with ultrasonography and found to have no gallbladder stones, 503 (81.0 per cent) were re-examined after a minimum interval of 5 years. At baseline and re-examination, heredity for gallstone disease was explored and body mass index, digestive symptoms including abdominal pain, quality of life, alcohol and smoking habits, use of non-steroidal anti-inflammatory drugs and oestrogen, parity and blood lipid levels were recorded. Results: Forty-two (8.3 per cent) of the 503 subjects developed stones. Subjects were followed for a total of 3025.8 person-years, yielding an incidence for newly developed gallstones of 1.39 per 100 person-years. A positive association for gallstone development,was found only for length of follow-up and plasma low-density lipoprotein-cholesterol levels at baseline. Weekly alcohol consumption was inversely related to gallstone development. Conclusion: The incidence of gallstones in this population was 1.39 per 100 person-years. Gallstone development was related to length of follow-up and LDL-cholesterol levels, and inversely related to alcohol consumption.

    Acupuncture treatment of vasomotor symptoms in men with prostatic carcinoma: A pilot study1999In: Journal of Urology, ISSN 0022-5347, E-ISSN 1527-3792, Vol. 161, no 3, p. 853-856Article in journal (Refereed)
    Abstract [en]

    PURPOSE: Most men who undergo castration therapy for prostatic carcinoma will have vasomotor symptoms that usually persist for years. Vasomotor symptoms are elicited from the thermoregulatory center, possibly due to a decrease in hypothalamic opioid activity induced by low sex steroid concentrations. Acupuncture treatment in women, which stimulates hypothalamic opioid activity, alleviates vasomotor symptoms. We report on men treated with acupuncture for relief of vasomotor symptoms after castration therapy.

    MATERIALS AND METHODS: We asked 7 men with vasomotor symptoms due to castration therapy to receive acupuncture treatment 30 minutes twice weekly for 2 weeks and once a week for 10 weeks. Effects on flushes were recorded in logbooks.

    RESULTS: Of the 7 men 6 completed at least 10 weeks of acupuncture therapy and all had a substantial decrease in the number of hot flushes (average 70% after 10 weeks). At 3 months after the last treatment the number of flushes was 50% lower than before therapy. Therapy was discontinued after 10 weeks because of a femoral neck fracture in 1 man and after 3 weeks due to severe back pain in 1.

    CONCLUSIONS: Acupuncture may be a therapeutic alternative in men with hot flushes after castration therapy and merits further evaluation.

    Few oligo-amenorrheic athletes have vasomotor symptoms2000In: Maturitas, ISSN 0378-5122, E-ISSN 1873-4111, Vol. 34, no 3, p. 219-225Article in journal (Refereed)
    Abstract [en]

    Objective: To assess whether women with athletic oligo-amenorrhea have vasomotor symptoms. Material and methods: A mailed questionnaire was sent to 252 female athletes about vasomotor symptoms. Identical questions were also mailed to 1523 peri- and postmenopausal women. Results: The prevalence of vasomotor symptoms was low in female athletes with oligo- and amenorrhea and similar to that found in athletes with regular menstruations. The prevalence was significantly lower than in menopausal women. Although more than a third of the menopausal women had hormone replacement therapy, 30% of them still had vasomotor symptoms at least every week compared with only 2% of the oligo-amenorrheic athletes. Conclusion: Vasomotor symptoms are very uncommon in oligo-amenorrheic athletes, although many of them are hypoestrogenic. It was suggested that one factor contributing to these symptoms around menopause is low hypothalamic activity of ▀-endorphins, which makes the thermoregulatory centre labile. On the other hand, supraphysiological activity in hypothalamic ▀-endorphins may cause the oligo-amenorrhea in athletes, but may stabilise the thermoregulatory centre and thus prevent hot flushes.

    IGHV3-21 stereotyped subset-2 chronic lymphocytic leukemia cells make autoantibodies that bind to an 11.5kDa gastric mucosal antigenManuscript (preprint) (Other academic)
    Abstract [en]

    Background: The immunoglobulin heavy chain variable region (IGHV) gene mutational status is an important prognostic factor in chronic lymphocytic leukemia (CLL). Patients with mutated IGHV genes show significantly longer survival than unmutated cases. CLL patients with mutated IGHV3-21 genes, however, have a shorter survival compared to other mutated CLL cases. Recently, we showed that CLL cells react with oxidized epitopes exposed on apoptotic cells and bacteria. The gastric mucosal reactivity was of special interest to further characterize in detail.

    Methods: We collected corpus biopsies from seven Helicobacter pylori (H.p.)+ study subjects withnon-atrophic gastritis, six subjects with H.p.- atrophic gastritis, eight subjects with H.p.+ atrophicgastric and from eight controls without gastritis. The binding pattern of CLL subset-2 IGHV3-21antibodies was analyzed by immunohistochemistry and the antigen was biochemically purified byaffinity chromatography.

    Results: The subset-2 IGHV3-21 Abs bound to mucosal glands in 18 of 29 cases regardless of H.p.status or diagnosis. It also showed staining of connective tissue in all of the biopsies. The antigen waspurified and a protein of 11.5 kDa MW was isolated.

    Conclusion: The results from this study indicate that IGHV3-21 subset-2 CLL Abs bind an 11.5kDaprotein present in gastric mucosal glands or connective tissue. This autoantigen has no associationwith H.p. since it is present in normal, non-atrophic H.p.+ and atrophic H.p.+/H.p.- gastric mucosafrom corpus. The exact nature of the 11.5 kDa protein is currently under detailed structure massspectrometry analysis in order to reveal whether bacterial mimicry is the mechanism behind theinduction of this particular autoantibody.

    Absolute risk reductions for local recurrence after postoperative radiotherapy after sector resection for ductal carcinoma in situ of the breast2008In: Journal of Clinical Oncology, ISSN 0732-183X, E-ISSN 1527-7755, Vol. 26, no 8, p. 1247-1252Article in journal (Refereed)
    Abstract [en]

    Purpose Evaluate the effects of radiotherapy after sector resection for ductal carcinoma in situ of the breast (DCIS) in patient groups as defined by age, size of the lesion, focality, completeness of excision and mode of detection. Patients and Methods A total of 1,067 women in Sweden were randomly assigned to either postoperative radiotherapy (RT) or control from 1987 to 1999, and 1,046 were followed for a mean of 8 years. The main outcome was new ipsilateral breast cancer events and distant metastasis-free survival analyzed according to intention to treat. Results There were 64 ipsilateral events in the RT arm and 141 in the control group corresponding to a risk reduction of 16.0 percentage points at 10 years (95% CI, 10.3% to 21.6%) and a relative risk of 0.40 (95% CI, 0.30 to 0.54). There was no statistically significant difference in distant metastasis free survival. There was an effect modification by age, yielding a low effect of RT in women younger than 50, but substantial protection in women older than 60 years. The age effect was not confounded by focality, lesion size, completeness of excision, or detection mode. There was no group as defined by our stratification variables that had a low risk without radiotherapy. Conclusion Our results indicate that younger women have a low protective effect of conventional RT after sector resection. Older women benefit substantially. We caution that the age effect was seen in a subgroup analysis. Further search with conventional clinical variables for a low risk group that does not need RT does not seem fruitful.

    Riktlinjer för handläggning av patienter med pankreascancer [Guidelines for management of patients with pancreatic cancer]2002In: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 99, no 15, p. 1676-1685Article in journal (Other academic)
    Abstract [sv]

    Transabdominellt ultraljud är förstahandsundersökning vid misstänkt pankreascancer, följt av spiral-DT eller MR för mer definitiv diagnos. Tumörmarkörer har ingen plats i rutindiagnostiken. Spiral-DT är basen i resektabilitetsbedömningen. Resektion av tumören är en förutsättning för bot. Ett samband har påvisats mellan antalet resektioner som görs vid ett sjukhus årligen och postoperativ mortalitet. Långtidsöverlevnaden efter resektion är oförändrat kort medan postoperativ mortalitet minskat dramatiskt vid enheter som rapporterat sina resultat. Adjuvant behandling efter resektion bör endast ges inom ramen för kliniska studier. Det palliativa omhändertagandet har förbättrats främst genom utveckling inom endoskopi, interventionell radiologi, smärt- och nutritionsbehandling. Palliativ cytostatikabehandling bör endast ges selektivt utanför kliniska studier. Radioterapi har ingen dokumenterad effekt på överlevnaden vid icke-resektabel pankreascancer. Internationellt rekommenderas speciella behandlingsteam för pankreascancer med tillräckliga upptagningsområden (2–4 miljoner invånare).
