Abstract
STUDY QUESTION Is prior testicular torsion associated with testicular function (semen quality and reproductive hormones) in young men from the general population? SUMMARY ANSWER In young men from the general population, no differences in semen parameters were observed in those who had experienced testicular torsion compared to controls and observations of higher FSH and lower inhibin B were subtle. WHAT IS KNOWN ALREADY Testicular function may be impaired after testicular torsion, but knowledge is sparse and based on studies with small sample sizes and no control group or a less than ideal control group. STUDY DESIGN, SIZE, DURATION A cross-sectional population-based study was carried out including 7876 young Danish men with unknown fertility potential, examined from 1996 to 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS All men (median age 19.0 years) had a physical examination, provided a blood and semen sample, and filled in a questionnaire including information about prior testicular torsion, birth, lifestyle and current and previous diseases. Markers of testicular function, including testis volume, semen parameters and reproductive hormones, were compared between men operated for testicular torsion and controls, using multiple linear regression analyses. MAIN RESULTS AND THE ROLE OF CHANCE The average participation rate was 24% for the entire study period. In total, 57 men (0.72%) were previously operated for testicular torsion (median age at surgery 13.4 years) of which five had only one remaining testicle. Men with prior testicular torsion were more often born preterm (25% versus 9.5% among controls), and they had significantly higher FSH and lower inhibin B levels, and a lower inhibin B/FSH ratio than controls in crude and adjusted models. The association was mainly driven by the subgroup of men who had undergone unilateral orchiectomy. No differences in semen parameters were observed. LIMITATIONS, REASONS FOR CAUTION A limitation is the retrospective self-reported information on testicular torsion. Also, results should be interpreted with caution owing to the high uncertainty of the observed differences. WIDER IMPLICATIONS OF THE FINDINGS Overall, the results of our study are reassuring for men who have experienced testicular torsion, especially when treated with orchiopexy, for whom reproductive hormone alterations were subtle and without obvious clinical relevance. Our study found no differences in semen parameters, but follow-up studies are needed to assess any long-term consequences for fertility.

Abstract
Abstract
Introduction/Objective
Ataxia-pancytopenia syndrome is caused by mutations in SAMD9L, a tumor suppressor gene on chromosome 7 with roles in normal hematopoiesis and cerebellar development. Syndrome manifestations consist of a combination of progressive ataxia, multilineage cytopenias, and increased risk of myeloid neoplasms associated with monosomy 7. Histopathologic and radiologic descriptions of this recently described disorder are scarce and treatment strategies are not standardized. Additionally, features that predict spontaneous hematologic remission of myeloid neoplasms are incompletely understood. Therefore, detailed discussions of this disorder and its possible outcomes are warranted.
Methods/Case Report
A six-year-old boy was brought to his doctor when his parents noticed head tilting while reading and impaired coordination. Brain MRI revealed extensive T2/FLAIR hyperintensities of white matter, cerebellar hypoplasia, and a thinned corpus callosum. Further evaluation excluded autoimmune etiologies, infectious diseases, and inherited leukodystrophies. Whole exome sequencing demonstrated a previously uncharacterized heterozygous mutation in SAMD9L, c.2062T>A; p.Tyr688Asn. Subsequent testing revealed pancytopenia. A bone marrow biopsy showed small megakaryocytes with abnormal nuclear lobation and erythroid progenitors with nuclear blebbing and binucleation. Blasts were borderline increased (4%). Fluorescence in-situ hybridization and karyotype showed monosomy 7. A myeloid next-generation sequencing panel identified an ETV6 mutation (p.Gln143Ter, VAF=5.4%). A diagnosis of myelodysplastic syndrome with monosomy 7 in the setting of ataxia-pancytopenia syndrome was rendered. The patient underwent allogeneic stem cell transplant and is doing well at last follow-up.
Results (if a Case Study enter NA)
N/A
Conclusion
Ataxia pancytopenia syndrome is a recently described and incompletely understood disorder. Some myeloid neoplasms in ataxia-pancytopenia syndrome can undergo somatic revertant mosaicism via uniparental disomy, resulting in spontaneous hematologic remission. Factors that predict spontaneous remission are unclear; however, secondary mutations have been associated with poorer outcomes. This case emphasizes the value of comprehensive genetic testing modalities in challenging cases. Screening for SAMD9L mutations in cases of pediatric myelodysplastic syndrome could be considered.

Abstract
PURPOSE More long-term follow-up studies beyond 10 years after secondary sphincteroplasty for obstetric damage are warranted. This prospective study aimed to compare reported data on incontinence and satisfaction in a cohort of such patients examined at short-, long-, and very long-term follow-up. METHODS Twenty out of 33 obstetric patients (61%) operated with secondary anterior overlapping sphincteroplasty during February 1996 to April 2004 were evaluated preoperatively and at short-, long-, and very long-term follow-up. Anal incontinence was scored by a combination of Wexner's and St. Mark's incontinence scores. The patients also reported degree of treatment satisfaction. RESULTS Twenty patients were examined preoperatively and after a median (range) of 5 (2-62), 102 (64-162), and 220 (183-278) months. Corresponding incontinence scores were 11.5 (5-18), 5.5 (1-17) (p < 0.01), 10.0 (0-18) (p > 0.05), and 12.0. (1-18) (p > 0.05). With increasing follow-up times, patients reporting a better outcome were 75%, 65%, and 45%. At very long-term follow-up patients, reports were more dismal than expected in those also reporting improved incontinence cores. Incontinence scores did not improve in patients with neuropathy (n = 5) or patients (n = 5) with more than 10 years of symptoms. CONCLUSION Initial improvement of anal incontinence attenuated with time, in particular from short- to long-term follow-up. Patients with neuropathy experienced no improvement of incontinence. Beyond stoma formation, in compliant patients, one should consider other treatment options like sacral nerve stimulation and neosphincter formation.

Abstract
STUDY QUESTION Are infertile men with reduced semen quality at risk of a further decrease in testicular function? SUMMARY ANSWER Infertile men with severely reduced semen quality risk further deterioration of semen quality 15 years after treatment for infertility, and a lower baseline sperm concentration was associated with a more pronounced increase in LH and decrease in testosterone/LH ratio at follow-up. WHAT IS KNOWN ALREADY Male factors account for up to 50% of human infertility. The most common finding is spermatogenic failure (SgF) yet the life course of semen quality and testosterone production in such men has not been described. STUDY DESIGN, SIZE, DURATION A follow-up study of men with SgF was performed 15 years after the initial infertility assessment between January 1995 and December 2000. PARTICIPANTS/MATERIALS, SETTING, METHODS Hospital records were used to identify potential participants in the study. A total of 137 men with primary male infertility due to SgF and 70 controls with good semen quality from couples with female factor infertility who attended a tertiary referral centre were included: the participation rate was 31% and 26%, respectively. The men provided semen samples and underwent a physical examination. Blood samples were taken to measure levels of reproductive hormones (FSH, LH, testosterone, sex hormone-binding globulin, estradiol and inhibin B). Current results were compared with results from the initial assessments. MAIN RESULTS AND THE ROLE OF CHANCE At the time of follow up the SgF men had significantly lower Leydig cell capacity than the control group as well as much lower semen quality. For the SgF men, between baseline sampling and follow up, the median sperm concentration decreased from 1.9 to 0.6 mill/ml and total sperm count from 7.7 to 2.0 million (P = 0.019 and 0.012, respectively), and 10% developed azoospermia. Calculated free testosterone (cFT), but not total testosterone (tT) decreased in the SgF group by ~0.6% (95% CI 0.1-1.2%) per year. In the SgF group, LH increased by 1.6% (CI 0.9-2.3%) annually, and consequently tT/LH and cFT/LH ratios had decreased by 1.3% (CI 0.5-2.1) and 2.1% (CI 1.2-3.0%), respectively. The increase in LH and the decreases in tT/LH and cFT/LH ratios were more pronounced in men with lower baseline sperm concentrations. LIMITATIONS, REASONS FOR CAUTION We consider the case group as representative of infertile men not in need of testosterone treatment at baseline investigation, but do not have information on those that chose not to participate in the follow-up study. There were alterations in some hormone analysis methods during the follow-up period that may introduce uncertainty in interpretation of long-term changes in hormone levels despite rigorous quality control. The validity of the control group suffers from a lack of hormone values at baseline. Also, at follow-up, for practical reasons only one semen sample could be obtained, which makes the effect estimate more uncertain and there is a risk of non-differential misclassification. WIDER IMPLICATIONS OF THE FINDINGS Without being able to predict individual outcomes, it is prudent to consider sperm cryopreservation or advise not to postpone fertility treatment when men present with infertility due to impaired semen quality. Whether partly compensated Leydig cell insufficiency in men with SgF will eventually develop into overt testosterone deficiency cannot be determined from our study.

Abstract
STUDY QUESTION How are temporal trends in lifestyle factors, including exposure to maternal smoking in utero, associated to semen quality in young men from the general population? SUMMARY ANSWER Exposure to maternal smoking was associated with lower sperm counts but no overall increase in sperm counts was observed during the study period despite a decrease in this exposure. WHAT IS KNOWN ALREADY Meta-analyses suggest a continuous decline in semen quality but few studies have investigated temporal trends in unselected populations recruited and analysed with the same protocol over a long period and none have studied simultaneous trends in lifestyle factors. STUDY DESIGN, SIZE, DURATION Cross-sectional population-based study including ~300 participants per year (total number = 6386) between 1996 and 2016. PARTICIPANTS/MATERIALS, SETTING, METHODS The study is based on men from the Greater Copenhagen area, Denmark, with a median age of 19 years, and unselected with regard to fertility status and semen quality. The men delivered a semen sample, had a blood sample drawn and a physical examination performed and answered a comprehensive questionnaire, including information on lifestyle and the mother's pregnancy. Temporal trends in semen quality and lifestyle were illustrated graphically, and trends in semen parameters and the impact of prenatal and current lifestyle factors were explored in multiple regression analyses. MAIN RESULTS AND THE ROLE OF CHANCE Throughout the study period, 35% of the men had low semen quality. Overall, there were no persistent temporal trends in semen quality, testicular volume or levels of follicle-stimulating hormone over the 21 years studied. The men's alcohol intake was lowest between 2011 and 2016, whereas BMI, use of medication and smoking showed no clear temporal trends. Parental age increased, and exposure in utero to maternal smoking declined from 40% among men investigated in 1996-2000 to 18% among men investigated in 2011-2016. Exposure to maternal smoking was associated with lower sperm counts but no overall increase in sperm counts was observed despite the decrease in this exposure. LIMITATIONS, REASONS FOR CAUTION Information of current and prenatal lifestyle was obtained by self-report, and the men delivered only one semen sample each. WIDER IMPLICATIONS OF THE FINDINGS The significant decline in in utero exposure to maternal smoking, which was not reflected in an overall improvement of semen quality at the population level, suggest that other unknown adverse factors may maintain the low semen quality among Danish men. STUDY FUNDING/COMPETING INTEREST(S) The study has received financial support from the ReproUnion; the Research fund of Rigshospitalet, Copenhagen University Hospital; the European Union (Contract numbers BMH4-CT96-0314,QLK4-CT-1999-01422, QLK4-CT-2002-00603, FP7/2007-2013, DEER Grant agreement no. 212844); the Danish Ministry of Health; the Danish Environmental Protection Agency; A.P.

Abstract
SummaryTo gain further information about the protective effect of phospholipase C (PLC) against intravascular coagulation, we have carried out studies in sheep. Thromboplastin infusions gave a dose-dependent increase in pulmonary platelet-bound 11 inactivity and a dose-dependent decrease in arterial oxygen tension, factor VIIIc activity, fibrinogen level and platelet count. All these parameters were significantly correlated when doses of 0.4 – 0.5 ml bovine thromboplastin/kg/min were given. The model therefore seemed suitable for testing the effect of PLC in preventing intravascular coagulation elicited by infusion of thromboplastin. Our experiments show that PLC may have a certain protective effect against pulmonary microembolism caused by thromboplastin infusion, but there was no normalization of the pulmonary 111In-radioactivity from labelled platelets, arterial oxygen tension, coagulation factors or platelet count in contrast to earlier observations in rats. Protection was observed against the effect of lethal doses of thromboplastin, but although small doses of PLC were used, both sheep eventually died of PLC toxicity.

Abstract
OBJECTIVE To study short- and long-term improvement in obstetric anal incontinence after secondary overlapping sphincteroplasty and repeat repairs. DESIGN A prospective analysis based on incontinence scores and patient satisfaction. SETTING Department of Gastroenterological Surgery, Oslo University Hospital, a tertiary unit also dealing with sphincter repair. POPULATION Of 40 obstetric patients operated consecutively from February 1996 to April 2004, 33 (83%) patients with median age of 36 years were eligible for evaluation. METHODS Wexner's and St. Mark's incontinence score, clinical examination, anal ultrasonography and manometry, and neurophysiological examination when indicated. Patient satisfaction to treatment was recorded. The patients had anterior overlapping sphincteroplasty. Five had repeat operations, four sphincteroplasty and two post-anal repair. MAIN OUTCOME MEASURES Anal incontinence, patient satisfaction. RESULTS The 33 patients were examined after median 7 (range 2-62) months and 103 (62-162) months. Median incontinence scores preoperatively and after short- and long-term follow-up were 12 (5-20), 7 (5-20) (p < 0.01) and 9 (0-18) (p < 0.05), respectively. Three patients (9%) had normalized anal incontinence (score ≤1) after short- and long-term follow-up. Corresponding numbers for improved anal incontinence were 22 (67%) and 16 (49%), respectively. Improvement in incontinence scores and patients' satisfaction were concordant. Symptom duration (n = 7), pudendal neuropathy (n = 6), repeat repair (n = 5) and instrument delivery (n = 3) were associated with adverse outcome. CONCLUSIONS Improvement in anal incontinence at short-term follow-up is attenuated at long-term follow-up. Stoma formation, sacral nerve stimulation and neo-sphincter formation must be considered in compliant patients.

Abstract
BACKGROUND Knowledge about female sexual problems after pre- or postoperative (chemo-)radiotherapy and radical resection of rectal cancer is limited. The aim of this study was to compare self-rated sexual functioning in women treated with or without radiotherapy (RT+ vs. RT-), at least two years after surgery for rectal cancer. METHODS AND MATERIALS Female patients diagnosed from 1993 to 2003 were identified from a national database, the Norwegian Rectal Cancer Registry. Eligible patients were without recurrence or metastases at the time of the study. The Sexual function and Vaginal Changes Questionnaire (SVQ) was used to measure sexual functioning. RESULTS Questionnaires were returned from 172 of 332 invited and eligible women (52%). The mean age was 65 years (range 42-79) and the time since surgery for rectal cancer was 4.5 years (range 2.6-12.4). Sexual interest was not significantly impaired in RT+ (n=62) compared to RT- (n=110) women. RT+ women reported more vaginal problems in terms of vaginal dryness (50% vs. 24%), dyspareunia (35% vs. 11%) and reduced vaginal dimension (35% vs. 6%) compared with RT- patients; however, they did not have significantly more worries about their sex life. CONCLUSION An increased risk of dyspareunia and vaginal dryness was observed in women following surgery combined with (chemo-)radiotherapy compared with women treated with surgery alone. Further research is required to determine the effect of adjuvant therapy on female sexual function.

Abstract
SAMMENDRAGResultatene etter operasjon for kreft i endetarmen har vært preget av høy frekvens av lokalt residiv og deravlav overlevelse. Resultater blant kurativt opererte i Norge i perioden 1986-88 viste at 28% utviklet lokaltresidiv og bare 55% overlevde fem år. For å bedre prognosen ved endetarmskreft (rectumcancer) ble det i1993 startet et nasjonalt prosjekt, og hensikten med denne studien er å evaluere effekten av de tiltak som bleiverksatt for å heve kvaliteten av behandlingen. Prosjektet har fokusert på å optimalisere kirurgisk behandlingved å innføre operasjonsmetoden ”Total Mesorectal Excision” (TME). I tillegg har en lagt vekt på åstandardisere de patologisk anatomiske undersøkelsene. En rekke kurs er blitt arrangert for å lære kirurgeneden nye operasjonsteknikken, mens patologer har gjennomgått kurs for å sikre kvaliteten i vurderingen avoperasjonspreparatene. Et nasjonalt register for endetarmskreft, etablert og drevet av fagmiljøene, ble opprettetved Kreftregisteret. Fra dette sentrale Rectumcancerregisteret får alle kirurgiske avdelinger regelmessigetilbakemeldinger om sine egne resultater. Fra november 1993 til desember 1999 ble det diagnostisert5382 nye tilfeller av endetarmskreft i Norge. Blant de 3432 (64%) som ble kurativt operert var det 8% somutviklet lokalt residiv etter en median observasjonstid på 31 måneder, og av de under 75 år var den estimerte5-års overlevelsen 71%. I 1999 ble mer enn 95% av pasientene operert med TME teknikken. Det nasjonalesamarbeidsprosjektet for kreft i endetarmen har hittil redusert frekvensen av lokale residiver fra 28% til 8%og øket 5-års overlevelsen fra 55% til 71%.

Abstract
Differentiation between malignant and benign pheochromocytomas of the adrenal gland traditionally relies on the presence of clinically detectable metastases. The PASS system for differentiating between benign and malignant pheochromocytomas is based on defined morphological criteria, of which some are related to tumour cell proliferation and survival. Immunohistochemical markers for important events in the cell cycle were explored in order to characterise differences in apoptosis, G1 checkpoints, and S phase in more detail. A panel consisting of p53, tenascin, bcl-2, pRb, cyclin D1, mcm2, and p27 was employed. Only for pRb a statistically significant difference between PASS 3 and less and PASS 4+ tumours was detected, indicating qualitative differences in the mitotic cycle, probably immediately before early S phase. These results are discussed in relation to similar studies in recent literature.

Abstract
BACKGROUND The recommendation of adjuvant chemotherapy for colon cancer with lymph node metastases, based on two studies from USA, was reluctantly accepted by Norwegian medical doctors. It was therefore decided to assess the role of adjuvant therapy with 5fluorouracil (5-FU) combined with levamisole (Lev) in a confirmatory randomised study. MATERIAL AND METHODS Four hundred and twenty five patients with operable colon and rectum cancer, Stage II and III (Dukes' stage B and C), were from January 1993 to October 1996, included in a randomised multicentre trial in Norway. The age limits were 18-75 years. Therapy started with a loading course of bolus i.v. 5-FU (450 mg/m(2)) daily for 5 days and p.o. doses of Lev (50 mg x 3) for 3 days. From day 28 a weekly i.v. 5-FU dose (450 mg/m(2)) were administered for 48 weeks. From day 28 also p.o. doses of Lev (50 mg x 3) for 3 days were given every 14 days. In total 214 patients were randomised to 5FU/Lev and 211 were included in the control group with surgery alone. Some did not comply with the inclusion and exclusion criteria, thus leaving 206 evaluable patients in each group. RESULTS There was no significant survival difference between the two groups at 5 years: Disease-free survival (DFS) was 73% after chemotherapy, 68% (p=0.24) in the control group, and corresponding cancer specific survival (CSS) 75% and 71%, respectively (p=0.69). There was no difference between the two groups when analysed for colon and rectum separately. However, the subgroup of colon cancer with stage III exhibited a statistically significant difference both for DFS, 58% vs. 37% (p=0.012) and CSS, 65% vs. 47% (p=0.032) in favour of adjuvant chemotherapy. The benefit was further statistically significant for women but not for men. Toxicity was generally mild and acceptable with no drug related fatalities. CONCLUSIONS Colon cancer patients with lymph node metastases benefit from adjuvant chemotherapy with 5-FU/Lev with acceptable toxicity. In a subgroup analysis females did better than males. Rectal cancer does not benefit from this regimen.

Abstract
PURPOSE There is little knowledge on long-term morbidity after radiotherapy (50 Gy) and total mesorectal excision for rectal cancer. Therefore, late effects on bowel, anorectal, and urinary function, and health-related quality of life (QoL), were studied in a national cohort (n = 535). METHODS AND MATERIALS All Norwegian patients who received pre- or postoperative (chemo-)radiotherapy for rectal cancer from 1993 to 2003 were identified. Patients treated with surgery alone served as controls. Patients were without recurrence or metastases. Bowel and urinary function was scored with the LENT SOMA scale and the St. Marks Score for fecal incontinence and QoL with the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30). RESULTS Median time since surgery was 4.8 years. Radiation-treated (RT+) patients (n = 199) had increased bowel frequency compared with non-radiation-treated (RT-) patients (n = 336); 19% vs. 6% had more than eight daily bowel movements (p < 0.001). In patients without stoma, a higher proportion of RT+ (n = 69) compared with RT- patients (n = 240), were incontinent for liquid stools (49% vs. 15%, p < 0.001), needed a sanitary pad (52% vs. 13%, p < 0.001), and lacked the ability to defer defecation (44% vs. 16%, p < 0.001). Daily urinary incontinence occurred more frequently after radiotherapy (9% vs. 2%, p = 0.001). Radiation-treated patients had worse social function than RT- patients, and patients with fecal or urinary incontinence had impaired scores for global quality of life and social function (p < 0.001). CONCLUSIONS Radiotherapy for rectal cancer is associated with considerable long-term effects on anorectal function, especially in terms of bowel frequency and fecal incontinence. RT+ patients have worse social function, and fecal incontinence has a negative impact on QoL.

Abstract
PURPOSE It is known that scattered radiation to the testes during pelvic radiotherapy can affect fertility, but there is little knowledge on its effects on male sex hormones. The aim of this study was to determine whether radiotherapy for rectal cancer affects testosterone production. METHODS AND MATERIALS All male patients who had received adjuvant radiotherapy for rectal cancer from 1993 to 2003 were identified from the Norwegian Rectal Cancer Registry. Patients treated with surgery alone were randomly selected from the same registry as control subjects. Serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and sex hormone binding globulin (SHBG) were analyzed, and free testosterone was calculated (N = 290). Information about the radiotherapy treatment was collected from the patient hospital charts. RESULTS Serum FSH was 3 times higher in the radiotherapy group than in the control group (median, 18.8 vs. 6.3 IU/L, p <0.001), and serum LH was 1.7 times higher (median, 7.5 vs. 4.5 IU/l, p <0.001). In the radiotherapy group, 27% of patients had testosterone levels below the reference range (8-35 nmol/L), compared with 10% of the nonirradiated patients (p <0.001). Irradiated patients had lower serum testosterone (mean, 11.1 vs. 13.4 nmol/L, p <0.001) and lower calculated free testosterone (mean, 214 vs. 235 pmol/L, p <0.05) than control subjects. Total testosterone, calculated free testosterone, and gonadotropins were related to the distance from the bony pelvic structures to the caudal field edge. CONCLUSIONS Increased serum levels of gonadotropins and subnormal serum levels of testosterone indicate that curative radiotherapy for rectal cancer can result in permanent testicular dysfunction.

Abstract
PURPOSE This study was designed to evaluate the effect of biofeedback and electrostimulation in a randomized, clinical trial for the treatment of patients with postdelivery anal incontinence. METHODS Forty-nine females who sustained third-degree or fourth-degree perineal rupture with a mean age of 36 (range, 22-44) years were included in the study. The females were randomized to biofeedback or electrostimulation treatment. Forty females completed the study: 19 in the biofeedback and 21 in the electrostimulation group. Biofeedback or electrostimulation sessions were performed two times daily for eight weeks in each group. Wexner incontinence score, fecal incontinence quality of life scores, and reduced quality of life on visual analog scale were registered before and after treatment. Patients' self-rating of treatment effect also was registered in both groups. The primary outcome measure was the Wexner incontinence score. RESULTS There were no differences in treatment effect between groups. Comparing pretreatment status to posttreatment in each group showed no improvement in Wexner score, reduced quality of life, or any of the fecal incontinence quality of life scores. Patients' self-rating of the treatment effect, however, showed a subjective improvement of symptoms both in the biofeedback and in the electrostimulation group (median, 7 vs. 5.) CONCLUSIONS This study shows that there was no difference in effect between biofeedback and electrostimulation. Neither biofeedback nor electrostimulation treatments improved Wexner incontinence score, reduced quality of life, or fecal incontinence quality of life scores. Both treatments resulted in improvement of patients' subjective perception of incontinence control.

Abstract
BACKGROUND AND AIMS The main aim was to examine constipation and anal incontinence in patients before and after resection for external rectal prolapse. MATERIAL AND METHODS Twenty patients had ligament preserving suture rectopexy and sigmoid resection (resection rectopexy) for external rectal prolapse by laparoscopic (n = 15) or open (n = 5) technique during 2001-2005. They were prospectively evaluated for constipation and anal incontinence using validated incontinence and KESS-constipation scores. RESULTS AND CONCLUSIONS Constipation score was significantly reduced from mean 7.7 (5.4-9.9) to 4.5 (2.5-6.4) after median 4 months (1-19) and to 4.3 (2.2-6.3) after median 17 months (4-51). Six and four patients were constipated preoperatively and 17 months postoperatively, respectively. The four symptoms feeling incomplete evacuation of stool, minutes in lavatory per attempt, use of enemas/digitation and painful evacuation effort were significantly reduced, whilst stool consistency increased. Fourteen patients (70%) had anal incontinence. Corresponding and significant reduction in their scores were from mean 12.5 (9.4-15.5) to 5.1 (2.1-8.1) and to 3.6 (1.3-5.9). Incontinence was improved in 13 and unaltered in one patient(s). Two patients with worse outcome had increased stool consistency and constipation scores. Resection rectopexy for rectal prolapse reduced anal incontinence and constipation.

Abstract
CONTEXT Primary hyperparathyroidism occurs in almost all patients with the syndrome of multiple endocrine neoplasia type 1 (MEN1), but the association of MEN1 with parathyroid carcinoma has only been described previously in a single patient. In this report, we describe two further cases of parathyroid carcinoma presenting in MEN1 syndrome. CASE REPORTS The first patient was a 69-yr-old woman, who presented with severe primary hyperparathyroidism and tracheal compression by a large mediastinal mass, which was shown histologically to be a parathyroid carcinoma with a second similar lesion in the neck. She was treated with total parathyroidectomy followed by resection of the mediastinal mass with resolution of the hypercalemia. Remarkably, she also reported primary amenorrhea and was found to have an invasive pituitary lactotroph adenoma, which was treated with cabergoline and external beam radiotherapy. Magnetic resonance imaging (MRI) of the pancreas revealed a small lesion characteristic of an islet-cell tumor, which was clinically and biochemically non-functioning. The second patient was a 32-yr-old man who presented with symptomatic hypercalemia and markedly raised serum PTH concentration. Neck exploration revealed two parathyroid glands only. One of the parathyroid glands contained a tumor with fibrous banding, atypical mitoses, extra-capsular extension and moderate Ki 67 staining; features which are highly suggestive of carcinoma. He also had intractable dyspepsia associated with raised serum gastrin concentration. A lesion was localized to the neck of the pancreas by endocopic ultrasound, and a selective arterial calcium stimulation catheter suggested the presence of both a gastrinoma and an insulinoma, although he had no hypoglycemic symptoms. Pituitary MRI was normal. The patient's mother had primary hyperparathyroidism. CONCLUSIONS This case report describes two further patients in whom parathyroid carcinomas occurred in the context of MEN1, which gives a new insight to the possible presenting phenotype of this condition. Both patients had negative genetic screening for classic MEN1 gene mutation, which may suggest that one or more novel occult mutations may be responsible for this aggressive phenotype.

Abstract
OBJECTIVE To assess the need for intestinal repeat resection for recurrence of Crohn's disease in patients observed for more than 20 years after the first resection. MATERIAL AND METHODS Data were gathered retrospectively from the medical records of 53 (28 F) consecutive patients with Crohn's disease from May 1954 to December 2002. Median age at first intestinal resection was 24.5 (range 13-65) years, and median observation time thereafter was 26.5 (20.1-48.6) years. Disease location and behaviour were defined according to the Vienna classification. RESULTS The 53 patients had an average 2.7 and a median 2 intestinal resections. Out of 144 intestinal resections (77.1%) 111 were performed during the first three operations; no alterations in distribution of ileal, ileocolic and colic resections were found. From the first to the third operation there was an increase in penetrating disease from 15% to 39% (p=0.046) concomitant with a decrease in stricturing disease from 72% to 44% (p=0.048) of the patients. There was also a corresponding decrease in ileocolic disease from 45% to 5% (p=0.003) and a tendency towards an increase in ileal disease from 38% to 67%. One patient died (1.8%) from rectosigmoid perforation after the third resectional operation. Six patients needed reoperation (11.3%) for ileus, anastomotic bleeding, rectosigmoidal perforation and abdominal pain. Thirty-four patients (64.2%) needed intestinal repeat resection (median 8.3 years) during 25.3 years after the first repeat resection. CONCLUSIONS This study indicates a diminution of Crohn's disease activity with time, as demonstrated by no need for intestinal repeat resection more than 25 years after the first resection.

Abstract
BACKGROUND Testicular germ cell tumours (TGCTs) originate from a common precursor, carcinoma in situ (CIS). Diagnosis at the CIS stage is desirable as it minimizes the necessary treatment. A detailed clinical evaluation of an approach to detect CIS cells in the ejaculate using primordial germ cell/gonocyte markers is presented. METHODS Immunocytological staining for AP-2gamma [and in some cases, OCT-3/4, NANOG or placental alkaline phosphatase (PLAP)] was performed in semen samples from 294 infertile patients and 209 patients with TGCTs or other diseases. RESULTS Presence of AP-2gamma-stained cells was detected in 50% of participants with CIS and in 33.9% of TGCT patients before treatment (non-seminomas: 56.6%, seminomas: 17.4%). OCT-3/4 results were similar to those of AP-2gamma, whereas NANOG and PLAP stainings were unsuitable. Sensitivity was 54.5% for participants harbouring pre-invasive CIS but reduced in participants with overt TGCTs, perhaps because of obstruction. Assay specificity was 93.6%, positive predictive value (PPV) 83.3% and negative predictive value (NPV) 60.3%. CONCLUSIONS Immunocytological semen analysis based on expression of fetal germ cell markers in exfoliated cells has auxiliary diagnostic value, as it detects some patients with CIS/incipient tumour, but a negative result does not exclude TGCT. Further effort is needed to improve this assay, for example, by employing a more sensitive biochemical method of detection.

Abstract
OBJECTIVE The purpose of this prospective study was to examine the influence of the efforts for nationwide quality assurance of rectal cancer treatment. The study focuses on local recurrence and overall survival. METHODS This study includes all 3388 Norwegian patients with a rectal cancer within 15 cm from the anal verge treated with curative intent in the period November 1993-December 1999. A comprehensive educational programme was established, and training courses were arranged in different Health Regions demonstrating the TME technique. A specific Rectal Cancer Registry enabled the monitoring of outcome of rectal cancer treatment for single hospitals. Radiotherapy was given to 10% of the patients. RESULTS The risk of local recurrence has been significantly reduced, so that in 1999 the level was 50% below that observed in 1994 (Hazard ratio (HR)1999=0.5; 95% CI 0.4-0.8, P=0.002). Similarly, during 1998, the mean national overall survival was significantly improved, compared to the rate in 1994 (HR1998=0.8; 95% CI 0.6-1.0, P=0.014). CONCLUSION The prognosis for rectal cancer can be improved by increased organizational focus on rectal cancer treatment and by establishing a rectal cancer registry monitoring treatment standards throughout the country.

Abstract
AIMS The aims of the study were (1) to evaluate quality of life (QoL) and functional outcome in patients following anterior resection (AR) or abdominoperineal resection (APR) for rectal cancer, and (2) whether these outcomes were dependent on the level of anastomosis. METHODS Patients who were without recurrent or metastatic disease were identified from the Norwegian Rectal Cancer Registry. QoL was assessed by the EORTC questionnaires QLQ-C30 and QLQ-CR38, and rectal function by a short questionnaire. Of 319 patients studied, 229 had undergone AR and 90 APR. The median age was 73 years, and the median time since surgery was 64 months. RESULTS Mean QoL scores for body image and male sexual problems were better following AR than APR (P<0.01), also in patients with a low (< or = 3 cm) anastomosis. Patients who had undergone AR had higher mean scores for constipation (P<0.001) and more often used anti-diarrhoeal medication (P=0.005), than patients who had undergone APR. Patients with a low anastomosis (< or = 3 cm) had more incontinence for gas and solid stools (P<0.05), and had more incontinence (P=0.006) compared with patients with higher anastomosis, but there was no difference in QoL. Subgroup analysis showed that irradiated patients (n=34) had worse rectal function in terms of frequency, urgency, and incontinence (P<0.01). CONCLUSIONS Although rectal function was impaired in patients with low anastomosis, patients who had undergone AR had better QoL than patients who had undergone APR.

Abstract
BACKGROUND It has been suggested that finger length may correlate with function or disorders of the male reproductive system. This is based on the HOXA and HOXD genes' common embryological control of finger development and differentiation of the genital bud. The objective of this study was to explore the association between the ratio of 2nd to 4th finger length (2D:4D ratio) and testis function in a sample of young Danish men from the general population. METHODS Semen samples and finger measurements were obtained from a total of 360 young Danish men in addition to blood samples for sex hormone analysis to describe the possible association between 2D:4D and semen and sex-hormone parameters. RESULTS A statistically significant inverse association with the 2D:4D was found only in relation to hormone levels of FSH in the group of young men with a 2D:4D >1 (P = 0.036) and a direct association with the total sperm count in the group of young men with a 2D:4D < or = 1 (P = 0.045). CONCLUSION The statistically significant results may be 'false positives' (type I error) rather than representing true associations. This relatively large study of young, normal Danish men shows no reliable association between 2D:4D finger ratio and testicular function. Measurements of finger lengths do not have the power to predict the testicular function of adult men.

Abstract
The incidence of testicular cancer is rising. Despite a high cure rate, efforts should be made to obtain diagnosis at the pre-invasive intratubular carcinoma in situ (CIS) stage, as the disease is potentially lethal and treatment has severe side-effects, especially regarding reproductive function. CIS diagnosis is presently only possible by a surgical biopsy of the testis. Immunocytological staining for transcription factor activator protein (AP-2gamma), previously identified as a marker for neoplastic germ cells, was performed in centrifuged samples of ejaculates obtained from 104 andrological patients, including patients with testicular cancer and subfertility. Cells positive for AP-2gamma were found only in semen samples from patients diagnosed a priori with testicular neoplasms and, surprisingly, in a 23 year old control subject with oligozoospermia and no symptoms of a germ cell tumour. Testicular biopsies performed during the follow-up of this patient revealed widespread CIS in one testicle, thus proving a potential diagnostic value of the new marker. For the first time, a patient without clinical symptoms of testicular neoplasia was diagnosed at the pre-invasive CIS stage using a new, simple method based on immunocytological staining of a semen sample for AP-2gamma, a novel marker for CIS. The value of this method for diagnostic use in the clinic requires further careful validation in a large series of patients and controls, but the preliminary results are promising.

Abstract
BACKGROUND The purpose of this study was to evaluate the results of surgery and stenting for operable and inoperable oesophageal cancer. MATERIAL AND METHODS Retrospective patient materials with resection (n = 65, 1983-2002) or stenting (n = 59, 1994-2003) for primary oesophageal cancer. RESULTS Mortality after surgery was 11% and 15% of the patients were re-operated. 36 (55%) had complications such as respiratory failure (n = 33), anastomotic dehiscence/perforation (n = 4), chylothorax (n = 1), haemorrhage (n = 3), wound rupture (n = 1), septicaemia (n = 2), arrhythmia (n = 4) and wound infection (n = 5). Median survival after surgery was 11 months. Survival after three years was 17%, after five years 8%. The stent procedure was without mortality but haemorrhage (n = 1) and stent dislocation (n = 2) occurred. 8 patients (14%) were re-stented for tumour stenosis (n = 6), fistula (n = 2) and dislocation (n = 1). Median survival after stenting was 78 days. Survival after 30 days was 80%, after one year 7%. INTERPRETATION Resectable oesophageal cancer should be operated in fit patients, as survival is improved and some patients can be cured. Stenting is the main option in inoperable patients.

Abstract
BACKGROUND Internal rectal intussusception, usually occurring in women, causes constipation and incomplete evacuation of stool. MATERIALS AND METHODS Twenty-one women and one man (median age 48) were operated with suture rectopexy and sigmoid resection. The patients were examined with anoscopy and defecography, and symptomatic outcome, patients' satisfaction and morbidity were evaluated. Outcome was based mainly on the validated KESS score for constipation. RESULTS There was a significant reduction in all ten symptoms. Faecal incontinence improved in the two afflicted patients after operation. The number of patients with constipation was reduced from 20 to 8 (p < 0.01); none became constipated. Mean (95 % CI) colonic transit times in ten constipated patients was reduced from 5.3 (4.1-6.4) to 4.0 (2.6-5.4) days (p = 0.08); seven of these patients had a reduction of transit time as well as constipation score. INTERPRETATION Rectopexy with sigmoid resection improved symptoms, including constipation and feeling of incomplete rectal emptying.

Abstract
BACKGROUND Anal fissure is very painful; surgery is warranted when medical treatment fails. MATERIAL AND METHOD We present a retrospective study of 34 patients (median age 42; 19-63) treated by subcutaneous lateral internal sphincterotomy (n = 27) and anal dilatation (n = 7) from 1992 to 2002, carried out by a questionnaire on pain, anal incontinence, and treatment result. RESULTS There were no complications or treatment for recurrence of anal fissure. Median pain score before surgery was 7.3 on a scale from 0 (no pain) to 10 (worst imaginable pain), median 73 months (4-124) after surgery the median score was 0 (0-5) (p = 0.00). For sphincterotomy (n = 27), the median score was 7.8 before surgery and 0 (0-5) after (p = 0.00), for anal dilatation 6 (3-10) before surgery and 2 (0-2) (p = 0.01) after. All patients had reduced pain scores after surgery but their incontinence scores remained unchanged. Two patients (7%) who had previously been dilated or irradiated developed faecal incontinence after sphincterotomy. More patients became asymptomatic after sphincterotomy (n = 18; 67%) than after anal dilatation (n = 4; 57%). INTERPRETATION Compared to anal dilatation, sphincterotomy offers better pain relief for anal fissure. Doing a shorter sphincterotomy corresponding to length of the fissure reduces the risk of anal incontinence.

Abstract
BACKGROUND The prevalence of anal sphincter rupture at vaginal delivery is from 0.5 to 2.5 %. More than 50 % of these patients may need a secondary anterior sphincteroplasty because of anal incontinence. MATERIALS AND METHODS We present prospective series of 29 women (median age 45 years) operated with an overlapping anterior sphincteroplasty from 1996 to 2001. The patients were examined with anal ultrasonography (n = 23), manometry (n = 19) and neurophysiologically (n = 13), and divided into group 1 (n = 19) with anal sphincter rupture and group 2 (n = 10) with sphincter rupture as well as pudendal neuropathy. All patients (n = 29) were examined with the Cleveland Clinic incontinence score before and median eight (2-64) months after operation. RESULTS Median incontinence score before and after operation was 11.0 (0-22) versus 5.0 (0-16) (p = 0.002) for group 1; 18.0 (15-24) versus 15.5 (11-24) (p = 0.034) for group 2. There was also a significant difference between the groups concerning incontinence scores both preoperatively (p = 0.045) and postoperatively (p = 0.028). An improvement of continence was seen in 15 (79 %) of the patients in group 1 compared to 4 patients (40 %) in group 2. In group 1 a significant increase of median resting and squeeze pressures was seen. INTERPRETATION Anterior sphincteroplasty improves anal continence considerably in patients with isolated sphincter rupture. However, patients with evidence of pudendal neuropathy must be informed that they should expect only a minor improvement in continence after operation.

Abstract
PURPOSE This study was conducted to investigate the long-term development of anal and urinary incontinence and to investigate the clinical value of electromyography and pudendal nerve terminal motor latency after obstetric anal sphincter rupture. METHODS One hundred females with obstetric anal sphincter rupture were evaluated by an anal incontinence questionnaire at 5 and 18 months postpartum and by a urine incontinence questionnaire at 18 months postpartum. Pudendal nerve terminal motor latency and electromyography examinations were performed on 68 and 67 females, respectively, at 10 months postpartum. RESULTS Fecal incontinence increased from 7 to 17 percent between 5 and 18 months (P = 0.04). At 18 months, the incidence of anal incontinence in females working outside the home (42/70 (60 percent)) was greater than that for females still at home with their child (12/30 (40 percent); P = 0.05). Anal incontinence at 18 months was significantly higher (P = 0.01) in subjects with pathologic electromyographic findings (76 percent) than in those with normal electromyography (45 percent; observed differences, 31 percent (95 percent confidence interval, 9 to 54 percent)). Thirty percent of the subjects had urinary stress incontinence. The risk of fecal urgency was greater in females with urinary urgency (difference, 44 percent; 95 percent confidence interval, 18 to 69 percent) and urinary stress incontinence (difference, 24 percent; 95 percent confidence interval, 3 to 44 percent) than in those without. CONCLUSION Fecal incontinence symptoms worsen with increased follow-up time, and the change in working status is the most likely explanation; therefore, early evaluation of bowel symptoms is misleading. Denervation injury of the anal sphincter is an independent risk factor for anal incontinence but has no association with urinary incontinence. Urinary urgency and stress incontinence symptoms are strongly associated with fecal urgency.

Abstract
OBJECTIVE To study the effect of rectopexy and sigmoid resection (resection rectopexy) on symptoms in patients with internal rectal intussusception. DESIGN Retrospective and prospective study. SETTING University hospital, Norway. PATIENTS 22 patients with internal rectal intussusception. INTERVENTIONS Resection rectopexy by an open (n = 13) or laparoscopically-assisted (n = 9) technique. MAIN OUTCOME MEASURES Symptomatic outcome, patients' satisfaction, and morbidity. Outcome was based mainly on the validated KESS score, which covers 10 symptoms included in the definiton of constipation. RESULTS There was a significant reduction in all 10 symptoms. Two patients complained of incontinence which improved after operation. The number of patients with constipation was reduced from 20 to 8 (p = 0.000) and none became constipated. Mean (95% CI) colonic transit times before and after operation in 10 patients with constipation were 5.3 (4.1 to 6.4) and 4.0 (2.6 to 5.4) days (p = 0.083). Seven of these 10 patients had a reduction of both transit time and constipation score. Six patients had complications after open operations. These included one damaged ureter, reoperations for bleeding, incomplete intestinal obstruction, and 2 wound infections. CONCLUSION Rectopexy with sigmoid resection resulted in improvement in symptoms, including constipation and feeling of incomplete rectal evacuation, and acceptable morbidity.

Abstract
PURPOSE The purpose of this study was to investigate the relationships between the grade of anal sphincter rupture, anal sphincter defect, manometry variables, and anal incontinence. METHODS A total of 132 females with first-time obstetric sphincter rupture were evaluated by transanal ultrasound, manometry, and scoring of bowel symptoms five months after delivery. RESULTS Anal sphincter rupture and transanal ultrasound grade correlated with each other ( rs= 0.427, P= 0.001). Both rupture and transanal ultrasound grade correlated with soiling grade ( rs= 0.2, P= 0.03 for both), but in a multiple regression analysis, only transanal ultrasound grade was significant ( P= 0.001) as an independent variable. Anal incontinence score correlated with all the manometry variables, but in a multiple regression analysis, only squeeze pressure was significant ( P= 0.001, beta = -0.4) as an independent variable. Both anal sphincter rupture and transanal ultrasound grade were correlated with manometry variables, but only transanal ultrasound grade was significant as an independent variable after multiple regression analysis. The frequency of transanal ultrasound-verified extensive defect of anal sphincter was higher in rupture Grade 3B (25; 95 percent confidence interval, 12-38 percent) and Grade 4 (45; 95 percent confidence interval, 24-66 percent) than in Grade 3A (2.8; 95 percent confidence interval, -1 to -6.6 percent).(s) (s)CONCLUSION Manometry variables are significantly lower in incontinent females than in continent females, and the Wexner incontinence score was correlated with manometry variables. Both anal sphincter rupture and transanal ultrasound grade correlated with soiling grade and with manometry variables, but in both cases only the transanal ultrasound grade was a significant independent variable.

Abstract
BACKGROUND The aim of this study was to determine whether there exists a correlation between anal incontinence, occult sphincter injuries, anal manometry values, and delivery variables in primiparous women after first time vaginal delivery. METHODS Eighty-six primigravida women were recruited for this study. Transanal ultrasonography (TAUS) and vector volume manometry (VVM) was performed and bowel symptoms were recorded at 25 weeks of pregnancy and 5 months after labor. Incontinent women at 5 months after vaginal delivery were interviewed again at 12 months. RESULTS Nineteen women (25%) experienced flatus incontinence postpartum. After 12 months, only one-third of the women were still incontinent. Fourteen women (19%) showed abnormal TAUS of the anal sphincter. Of the delivery variables, only baby head circumference was significantly associated with flatus incontinence (p = 0.01). There was no correlation between flatus incontinence or delivery variables and anal sphincter injuries; VVM values were not associated with either anal sphincter injuries or flatus incontinence at 5 months, but VVM values were negatively associated with flatus incontinence at 12 months after labor. CONCLUSIONS At 5 months after labor, flatus incontinence is relatively common, and is not associated with reduced VVM values. Two-thirds of women recover from flatus incontinence during the first year. Women who had flatus incontinence persisting for a minimum of 1 year had reduced VVM values. Anal sphincter injuries as seen by TAUS are not associated with either VVM values or any delivery variable. Baby head circumference is the only delivery variable significantly associated with flatus incontinence.

Abstract
INTRODUCTION Rectal cancer surgery has been characterized by a high incidence of local recurrence, an occurrence which influences survival negatively. In Norway there was a growing recognition that local recurrence rates were related to surgeon performance and that surgeons applying a standardized surgical technique in the form of total mesorectal excision could achieve better results. This contrasts with the prevailing argument voiced by many opinion leaders that local recurrence rates and possibly survival rates can only be improved by adjuvant or neoadjuvant treatment strategies. The Norwegian Rectal Cancer Project-initiated in 1993-aimed at improving the outcome of patients with rectal cancer by implementing total mesorectal excision as the standard rectal resection technique. METHODS This observational national cohort study covers all new patients (3,319) with rectal cancer from a population of 4.5 million treated between November 1993 and August 1997. The main outcome measures were local recurrence, survival, and postoperative mortality and morbidity rates. The technique of total mesorectal excision was compared with conventional surgery. RESULTS The proportion of patients undergoing total mesorectal excision was 78 percent in 1994, increasing to 92 percent in 1997. The observed local recurrence rate for patients undergoing a curative resection was 6 percent in the group treated by total mesorectal excision and 12 percent in the conventional surgery group. Four-year survival rate was 73 percent after total mesorectal excision and 60 percent after conventional surgery. Postoperative mortality rate was 3 percent and the anastomotic dehiscence rate was 10 percent. Radiotherapy was given to 5 percent and chemotherapy to 3 percent of the patients in the curative resection group. CONCLUSION A refinement of the surgical resection technique for rectal cancer can be achieved on a national level, the technique of total mesorectal excision can be widely distributed, and surgery alone can give good results.

Abstract
BACKGROUND In the past three decades, the incidence of colorectal cancer (CRC) in Norway has doubled, surpassing all other Nordic countries for both men and women to become the most frequently diagnosed cancer. A small-scale, randomized study on flexible sigmoidoscopy (FS) screening in Telemark, Norway, has shown a reduction in accumulated CRC incidence after 13 years. The aim of our study was to evaluate the effect on CRC mortality and morbidity by screen detection of CRC and removal of precursor lesions (polypectomy), and to test out the management and organization mimicking a countrywide screening service. A total of 13,823 men and women (1:1), age 55-64 years, were drawn randomly from the population registries in Oslo (urban) and the county of Telemark (mixed urban and rural) and invited to have a screening examination. The rest of the relevant age cohorts constituted the control groups. In the screening group, 535 individuals were excluded according to exclusion criteria, rendering 13,288 individuals eligible for screening examination. METHODS A once only screening model was used. In the screening group, individuals were randomized to have a once only FS or a combination of FS and faecal occult blood test (FOBT). RESULTS The overall attendance rate was 8,849 out of 13,288 (67%); 73% in Telemark and 60% in Oslo. Attendance for FS only was 68% and 65% for combined FS&FOBT. CONCLUSIONS The present FSIFS&FOBT screening study obtained a high acceptance rate for both screening modalities. The attendance rate was stable throughout the trial, suggesting an acceptable model for management of future countrywide screening.

Abstract
BACKGROUND We wanted to review patients operated for perforated peptic ulcer at Ullevål University Hospital, Oslo, Norway in the period 1992-1997. MATERIAL AND METHODS Data from 84 operated patients (43 men) were obtained retrospectively from patient and hospital files. Median age was 69 years (range 20-92 years). RESULTS 41 patients had perforated duodenal ulcer and 43 had perforated gastric ulcer (pylorus included). Median time from start of symptoms until admission to hospital was 5 hours (range 2-24 hours; n = 40) and from admission to start of surgery 5 hours (range 1 1/2-48 hours; n = 69). 64 out of 74 patients had pneumoperitoneum on preoperative abdominal X-ray examination. 77 patients were operated with rafi and/or tegmentation of the perforation; six patients with Billroth II or Billroth I; one patient was treated with percutaneous drainage. Median duration of surgery was 68 minutes (range 40-240 minutes). Thirteen patients died in hospital. Post-operative complications were recorded in 30 patients. INTERPRETATION Early surgical intervention is important to reduce lethality from ulcus perforatum. A patient with clinical peritonitis and suspected perforated peptic ulcer should be operated without time-consuming examinations.

Abstract
BACKGROUND The aim of this study was to examine whether the functional result of restorative proctocolectomy for ulcerative colitis deteriorated by postponing follow-up from three to eight years after pouch surgery. MATERIAL AND METHODS All patients (n = 58) operated for ulcerative colitis from 1984-97, who still had intact reservoir, responded to a questionnaire on defecating pattern, stool leakage, perianal irritation, urinary function, workload, sexual life, social life, and the patient's opinion on outcome. The results for the first 29 patients were compared to last 29 patients operated. Median follow-up was eight for the first 29 patients and three years for the last 29. RESULTS There were no significant difference in functional outcome and patient opinion after pouch surgery between the first 29 and last 29 patients (n = 58). Respective figures for median 24-hour stool frequency were 7.0 and 6.3, leakage of stool 48% and 38%, ability to defer defecation 86% and 97%, perianal irritation 59% and 48%, use of antidiarrhoeal medication 55% and 52%, and wearing of pad 28% and 38%. Sexual life (n = 57) had improved for 11 (19%) and deteriorated for seven patients (12%). Potency was reduced in five (15%) and ejaculation in four patients (12%), one of whom (3%) had retrograde ejaculation. Three (5%) had received a disability pension and five (9%) had reduced workload. After the pouch operation 48 (91%) felt better and three (6%) felt worse because of frequent bowel emptying (n = 3), perianal eczema (n = 1) and pouch fistula (n = 1). INTERPRETATION The results do not demonstrate any significant deterioration of functional outcome after pouch surgery for ulcerative colitis by postoperative increase of follow-up from three to eight years.

Abstract
OBJECTIVE To find out whether a threefold increase in follow up (median 108 compared with 36 months) influenced major morbidity and functional outcome between the first 32 and the last 32 patients consecutively operated on with J-pouch ileoanal anastomosis for ulcerative colitis from 1984 to 1997. DESIGN Retrospective and prospective study. SETTING University hospital, Norway. PATIENTS 64 patients with ulcerative colitis who had proctocolectomy and ileal pouch-anal anastomoses. INTERVENTIONS The pouches were mainly hand anastomosed (n = 61) to the dentate line after mucosectomy or anastomosed by double stapling technique without mucosectomy (n = 3). The 58 patients who still had their pouches responded to a questionnaire on functional outcome and satisfaction. MAIN OUTCOME MEASURES Morbidity, functional outcome, and patients' satisfaction. RESULTS Major morbidity in these 64 patients comprised pelvic sepsis in 3 (5%), operation for intestinal obstruction in 5 (8%), pouchitis in 12 (19%), fistulas in 7 (11%) and pouch excision in 6 (9%). Thirteen patients (20%) had 35 reoperations and 11 patients (17%) had 22 re-laparotomies. There were more complications among the first 32 patients with the longest follow up than among the last 32 patients, but this difference was significant only concerning the rate of reoperations (31% compared with 9%) because of the higher number of pouch excisions (5 compared with 1) in this group. There were no significant differences in the functional outcome and degree of patient satisfaction between the first 29 and the last 29 patients. Respective values for 24 hour median stool freqency were 7.0 and 6.3, leakage of stool 48% and 38%, ability to defer defaecation 86% and 97%, perineal irritation 59% and 48%, use of antidiarrhoeal medication 55% and 52%, and wearing of pad 28% and 38%. Sexual life (n = 57) was improved in 11 (19%) and reduced in 7 (12%). Potency was reduced in 5 (15%) and ejaculation in 4 (12%), one of whom (3%) had retrograde ejaculation. Three (5%) received disability pensions and five (9%) had reduced workload. After the pouch operation 48 (91%) felt better and 3 (6%) felt worse because of frequent bowel emptying, perineal eczema, or pouch fistula. CONCLUSION Continence-preserving proctocolectomy carries considerable morbidity, but the long term functional outcome is satisfactory and does not seem to deteriorate substantially.

Abstract
Inter-observer variation in andrological examination by 10 clinical investigators from five Nordic and Baltic countries was investigated. In addition, information on intra-observer variation was obtained for six of the 10 investigators. Testicular size was measured using Prader's orchidometer and one of the investigators also performed an ultrasound estimate of testicular size. A highly significant difference (p < 0.001) between observers was found with an inter-observer error of 16% in estimating testicular size in 23 young men. The difference in the estimate tended to increase with increasing testicular size. There was no significant intra-observer difference in two measurements performed on consecutive days. Only differences in median testis size, which were greater than 31% between measurements by two investigators, were found to be significant at the 5% level. The ultrasound estimate of testicular size was significantly lower than the orchidometer estimate, with a mean difference of 3.6 mL for the left testis and 4.3 mL for the right testis. Tanner staging of genitalia and diagnosis of a varicocele was subject to great inter-observer variation, and for the diagnosis of varicocele only one-third of the investigators was able to reproduce their results on a second examination. In conclusion, it was found that the clinical andrological examination of young men is subject to great inter-observer variation. This should be kept in mind when results from different studies are compared as well as in daily clinical practice.

Abstract
Male reproductive function seems to have deteriorated considerably during the past 4-5 decades. However, studies of the reproductive function in unselected populations have not previously been reported. As the large majority of young men in Denmark are subjected to a compulsory medical examination for military service, this provided a unique opportunity to study the reproductive function in an unbiased population. Altogether 891 young men delivered a blood sample in which reproductive hormones were measured. From 708 of these men data were also obtained on semen quality and testis size. The median sperm concentration was 41 x 10(6)/ml (mean 57.4 x 10(6)/ml). Men with ejaculation abstinence above 48 h had slightly higher sperm concentrations (median 45 x10(6)/ml, mean 63.2 x 10(6)/ml), but even in this subgroup, 21 and 43% respectively had sperm counts below 20 x 10(6)/ml and 40 x 10(6)/ml. Among men with no history of reproductive diseases and a period of abstinence above 48 h, as many as 18 and 40% respectively had concentrations below 20 and 40 x 10(6)/ml. Sperm counts were positively correlated with testis size, percentage normal spermatozoa and inhibin B, and negatively correlated with percentage immotile spermatozoa and follicle stimulating hormone. Possible causes for this high frequency of young men with suboptimal semen quality are obscure and need to be explored. Whether these findings apply for young male populations of comparable countries remains to be seen.
