RESUMO
OBJECTIVES: To assess the occurrence, clinical picture, and triggering infections of reactive arthritis (ReA) associated with a large waterborne gastroenteritis outbreak. METHODS: After an extensive sewage contamination of the water supply system, an estimated 8453 of the 30 016 inhabitants of the town of Nokia fell ill. General practitioners and occupational physicians were advised to refer any patients with suspicion of new ReA to rheumatological examination including faecal culture, human leucocyte antigen (HLA)-B27 and antibody tests for Campylobacter, Salmonella, and Yersinia. RESULTS: Forty-five patients (33 females, 12 males) aged 16-77 years (median 53) were referred. ReA was diagnosed in 21, postinfectious arthralgia in 13, and other musculoskeletal conditions in 11 patients. HLA-B27 was positive in five out of 44 patients (11%). Of the 21 patients with ReA, possible triggering infections were observed in seven (33%), Campylobacter in four, Yersinia in three, and Salmonella in one, who also had Campylobacter infection. ReA was mild in all but one patient who presented with persistent Salmonella enterica serotype enteritidis infection. CONCLUSIONS: Taking into account the large population contaminated with potentially arthritogenic agents, the occurrence of ReA was rare and mild in character.

An inappropriate cross-connection between sewage- and drinking-water pipelines contaminated tap water in a Finnish town, resulting in an extensive waterborne gastroenteritis outbreak in this developed country. According to a database and a line-list, altogether 1222 subjects sought medical care as a result of this exposure. Seven pathogens were found in patient samples of those who sought treatment. To establish the true disease burden from this exposure, we undertook a population-based questionnaire investigation with a control population, infrequently used to study waterborne outbreaks. The study covered three areas, contaminated and uncontaminated parts of the town and a control town. An estimated 8453 residents fell ill during the outbreak, the excess number of illnesses being 6501. Attack rates were 53% [95% confidence interval (CI) 49.5-56.4] in the contaminated area, 15.6% (95% CI 13.1-18.5) in the uncontaminated area and 6.5% (95% CI 4.8-8.8) in the control population. Using a control population allowed us to differentiate baseline morbidity from the observed morbidity caused by the water contamination, thus enabling a more accurate estimate of the disease burden of this outbreak.

OBJECTIVE: To compare among women with menorrhagia the effect of hysterectomy or levonorgestrel-releasing intrauterine system (LNG-IUS) on sexual functioning. DESIGN: A randomised controlled trial. SETTING: Five university hospitals in Finland. SAMPLE: A total of 236 women, aged 35-49 years. METHODS: Of the women, 117 were treated by hysterectomy and 119 by LNG-IUS. MAIN OUTCOME MEASURES: Sexual functioning was evaluated by modified McCoy sexual scale at baseline and at 6 months, 12 months, and 5 years after initiation of treatment (hysterectomy or application of LNG-IUS). RESULTS: Among women treated by hysterectomy, sexual satisfaction increased and sexual problems decreased. Among LNG-IUS users, satisfaction with partner decreased. In addition to treatment modality (P = 0.02), estrogen therapy (P = 0.01), smoking (P = 0.001), night sweats (P = 0.03), vaginal dryness (P = 0.04), hot flushes (P = 0.01), and having someone to ask for advice (P = 0.03) and to share worries (P = 0.01) explained changes in sexual functioning. CONCLUSIONS: Among women with menorrhagia, hysterectomy improves sexual functioning, whereas LNG-IUS does not have such a positive effect.

An initial improvement in glycemic control is often followed by gradual deterioration of glycemia during insulin treatment of patients with noninsulin-dependent diabetes mellitus (NIDDM). We examined the causes of such worsening in a 12-month follow-up analysis of 100 insulin-treated NIDDM patients in the Finnish Multicenter Insulin Therapy Study who were treated with either combination therapy with insulin or insulin alone. In the entire study group, glycemic control averaged 9.7 +/- 0.2% at 0 months and 8.0 +/- 0.1%, 8.0 +/- 0.1%, 8.2 +/- 0.1%, and 8.5 +/- 0.2% at 3, 6, 9, and 12 months (P < 0.001 for each time point vs. 0 months). Glycemic control at 12 months was significantly worse than that at 3 (P < 0.001), 6 (P < 0.001), and 9 months (P < 0.02). Baseline body mass index was the most significant predictor of deterioration in glycemic control. During 1 yr, hemoglobin A1c decreased almost 3-fold more (by 1.7 +/- 0.2%; P < 0.001 vs. 0 months) in patients whose baseline weight was below the mean baseline body mass index of 28.1 kg/m2 (nonobese patients) than in those whose weight exceeded 28.1 kg/m2 (obese patients; 0.5 +/- 0.2%; P = NS vs. 0 months; P < 0.01 vs. obese patients). Glycemic control improved similarly over 1 yr in the nonobese subjects and deteriorated similarly in the obese patients regardless of their treatment regimen. Insulin doses, per body weight, were similar in the nonobese and obese patients. The nonobese patients consistently gained less weight during 12 months of combination therapy with insulin (3.5 +/- 0.6 kg at 12 months) than during insulin therapy alone (5.1 +/- 0.6 kg; P < 0.05). The treatment regimen did not influence weight gain in the obese group, who gained 4.4 +/- 1.0 kg during combination therapy with insulin and 4.5 +/- 1.1 kg during insulin therapy alone. We reached the following conclusions: 1) after an initial good response, glycemic control deteriorates more in obese than in nonobese patients with NIDDM; 2) in obese patients, weight gain per se cannot explain the poor glycemic response to combination or insulin therapy, but it may induce a disproportionately large increase in insulin requirements because of greater insulin resistance in the obese than in the nonobese; 3) in nonobese patients, glycemic control improves equally during 1 yr with combination therapy with insulin and insulin alone, but combination therapy with insulin is associated with less weight gain than treatment with insulin alone; 4) weight gain appears harmful, as it is associated with increases in blood pressure and low density lipoprotein cholesterol.

Twenty-two perimenopausal patients (aged 47-56 years) admitted for elective abdominal hysterectomy and salpingo-oophorectomy were selected to understand better the clinical significance of increasing gonadotropin levels as an indicator of target organ responsiveness. Prior to anesthesia, blood was drawn from the patients for subsequent analyses of serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and 17beta-estradiol (E2) levels. Ovarian tissue was obtained during surgery and frozen at -70 degrees C for subsequent analyses for FSH and LH receptor content. The phase of the menstrual cycle of the patients or postmenopause was determined by serum gonadotropin and E2 levels and histological evaluation of the endometrium. Patients with no detectable FSH receptors showed significantly higher serum FSH and LH levels (4.7- and 4.3-fold, respectively) when compared to patients with detectable FSH receptors; FSH receptors were present in 27% of the patients, LH receptors were present in 68% of the patients and a negative correlation was found between serum LH levels and ovarian LH receptors. In postmenopausal patients, neither FSH receptors nor LH receptors were detectable. High serum gonadotropin levels in perimenopausal patients thus suggest the existence of low or undetectable ovarian gonadotropin receptor levels.

Simultaneous vasopressin concentrations in the preovulatory follicular fluid and plasma were determined for 12 patients with tubal infertility. Nine of the patients received clomiphene citrate, 100 mg daily, on cycle days 5 through 9. On the 11th day of the cycle, 5000 IU of hCG was given intramuscularly. At laparoscopy the ovarian follicles were aspirated 36 hours after hCG injection. For three patients the follicle aspiration was performed at laparotomy during the 11th-14th days of the normal cycle. In all these cases the vasopressin concentration in plasma exceeded markedly that in the follicular fluid. In the patients undergoing laparoscopy the vasopressin concentration in the follicular fluid was 11.2 +/- 8.2 pg/ml and that in plasma 17.3 +/- 22.0 pg/ml. It is most probable that the hormone enters fluid from the plasma.

OBJECTIVE: To determine whether the number of retrieved oocytes and the required amount of gonadotropins per oocyte in IVF treatment can be predicted with use of the following independent predictive variables: age, parity, cause of infertility, body mass index, day 3-5 FSH, E2, inhibin B, ovarian volume, the number of follicles, and intraovarian and uterine artery vascular resistance measured by ultrasonography before ovarian hyperstimulation. DESIGN: A retrospective analysis. SETTING: University hospital infertility clinic. PATIENT(S): Seventy-four consecutive women attending the university hospital infertility clinic for IVF treatment. INTERVENTION(S): The investigated factors were measured on day 3-5 of the cycle, in which luteal phase suppression was begun before ovarian hyperstimulation preparatory to IVF. MAIN OUTCOME MEASURE(S): The amount of gonadotropins required per oocyte and the number of retrieved oocytes were correlated with the predictive factors in stepwise regression analysis. RESULT(S): The best predictive factors for the number of oocytes retrieved were FSH, inhibin B, and parity, explaining 25% of the ovarian response. Intraovarian vascular resistance, parity, FSH, and inhibin B best predicted the amount of gonadotropins needed, explaining 44% of the variation. CONCLUSION(S): FSH, inhibin B, and parity were the independent predictive factors for the number of retrieved oocytes. The same factors and intraovarian vascular resistance predicted the required amount of gonadotropins per oocyte. The main part of the ovarian response cannot be predicted using the factors investigated.

The importance of monitoring luteinizing hormone (LH) secretion during gonadotropin stimulation remains controversial. In the present study, the authors evaluated the occurrence of spontaneous LH surges in 170 cycles stimulated by clomiphene citrate and human menopausal gonadotropin, and correlated the success rate of embryo cleavage to the time interval between the occurrence of the LH surge peak value and the time of human chorionic gonadotropin (hCG) administration. LH was quantitated from urine by an avidin-biotin enzyme immunoassay. The results indicated that a spontaneous LH surge occurred in 18% of the cycles. The number of oocytes recovered was not affected by the occurrence of a spontaneous LH surge. In 12% of all cases, the spontaneous LH surge occurred less than 12 hours before the administration of hCG, and in these cases embryo cleavage was not reduced. In 6% of all cases, the spontaneous LH surge occurred over 12 hours before hCG administration, and in these cases embryo cleavage was reduced significantly.

The purpose of this study was to investigate vascular resistance by Doppler ultrasound in the umbilical artery of insulin-dependent diabetics longitudinally over the course of pregnancy. Special interest was put on the effects of glycemic control and maternal vascular disease on the flow velocity waveform (FVW) and the predictive value of Doppler flow measurements with regard to perinatal morbidity. Using a duplex-pulsed wave scanner, the resistance-index (PR index) in the umbilical artery was calculated. The mean value of a 24-h blood glucose profile and the concentration of glycosylated hemoglobin (HBA1C) were used as parameters of metabolic control. 53 pregnant diabetic women were examined longitudinally during the course of pregnancy on average on three occasions (range: 1-7) between 17 weeks of gestation and delivery at 37.7 +/- 1.3 (mean +/- SD) weeks. To test the predictive value of Doppler flow velocimetry with regard to perinatal morbidity the results were compared to the FVWs measured in the umbilical arteries of 30 non-diabetic women with normal fetal outcome. Vascular resistance in the umbilical artery of the diabetics declined significantly during the course of pregnancy, with a mean PR index of 0.729 (SD 0.051) at 17 weeks and 0.603 (SD 0.083) at the end of pregnancy (P < 0.002). The majority of PR indices were within the range reported for normal pregnancy and measured in the non-diabetic women. Regression analysis showed no significant correlation between vascular resistance and mean blood glucose level (r = 0.1325) or concentration of HBA1C (r = -0.0519). Maternal vascular disease had no effect on umbilical FVWs.(ABSTRACT TRUNCATED AT 250 WORDS)

In this study we investigated the blood flow in uterine (u.a.) and ovarian arteries (o.a.) in healthy women and infertility patients and the relationship of vascular resistance to the etiology and the prognosis of infertility. A total of 101 consecutive infertility patients referred to hospital for investigations were studied by Doppler ultrasound. Couples with male infertility were excluded. The control group comprised 19 healthy women having regular menstrual cycle and no history of infertility. The pulsatility index (PI) in o.a. and u.a. was measured in pre- and post-ovulatory phase of the menstrual cycle. The PI values of the controls were compared with those of the patients with various infertility etiologies. The PI values of the infertility patients who subsequently delivered were compared with those of the patients failing to deliver. Infertility patients had high PI in o.a. and u.a. in the luteal phase more often than controls. High vascular resistance in u.a. and o.a. in the luteal phase reduce the take-baby-home rate.

OBJECTIVE: To investigate the correlation between the early follicular phase serum inhibin B levels and other indicators of ovarian reserve. STUDY DESIGN: Seventy-four women aged 24-40 years (mean 32) with different infertility etiologies were investigated in the early follicular phase of a spontaneous mentrual cycle. The volume of the ovaries was measured and the total number of follicles <5 mm in size counted by ultrasound. Serum levels of FSH, estradiol (E2) and inhibin B were measured on the same day. In stepwise regression analysis inhibin B levels were correlated with age, body-mass-index, the ultrasound measurements, cause of infertility, parity, FSH and E2. RESULTS: FSH, BMI and the number of follicles proved to be statistically significant independent predictive factors for the inhibin B levels, FSH and BMI correlating negatively and the number of follicles positively with inhibin B serum concentrations. CONCLUSION: The number of small follicles reflect the inhibin B production of the ovaries. BMI being as strong predictive factor of inhibin B levels as FSH could in part explain the impaired likelihood of conceiving in obese patients.

Seventy-nine patients were investigated by simultaneous urethrocystometry before and, on average, 15 months after vaginal and/or suprapubic operations for stress urinary incontinence. Subjective and objective success rates were 78% and 60%, respectively, with no significant differences between operation types. Patients with a low (less than 0.6) index of urethral relaxation at stress preoperatively indicating excessive loss of basal urethral pressure at stress, had objective success rates of 39% whereas a higher index was associated with a success rate of 70%. Maximal urethral closure pressure and functional urethral length did not correlate with the operative result and were virtually unchanged postoperatively. Successful operations increased the index of urethral relaxation at stress and urethral pressure peaks at stress especially in the distal functional urethra. No significant quantitative differences except for sling operations producing higher urethral closure pressure at stress in the proximal and lower in the distal functional urethra compared to the other operations were found. The results indicate, that successful operations eliminate the failure to maintain adequate basal urethral pressure at stress and emphasizes the importance of reflex activity of pelvic floor musculature at stress for continence.

One hundred and eighty-six deliveries from mothers of age 40 and over at Oulu University Central Hospital during 1975-77 are summarized. The commonest maternal complications were pre-eclampsia (25.8%) and pathological glucose tolerance (7.0%). The cesarean section rate of the whole group was 126.7%, and for the primiparas, 47%. Placental complications were slightly but not significantly more common among parturients over 40 compared with our general obstetric population. The pregnancies did not adversely affect the mothers' health despite commonly occurring maternal diseases. The commonest pathological findings among the newborns were hyperbilirubinemia (7.9%), neonatal infections (4.2%), clavicular fractures (3.2%) and postpartum asphyxia (2.6%). Congenital anomalies occurred in 2.6% of the children and were the main cause of the perinatal mortality, which was 5/189 (2.6%). Prematurity and low birth weight were not increased.

One-third of all women experience heavy menstrual bleeding at some point in their life. In western countries, about 5% of women of reproductive age will seek help for menorrhagia annually. Half of all women who consult for hypermenorrhea have some uterine abnormality, most often fibroids (among patients under 40 years of age) and endometrial polyps (above 40 years of age). Appropriate treatment considerably improves the quality of life of these patients, and it is important to make a rigorous assessment of the patient to provide the best treatment options. This guideline provides instructions on how to examine and treat women of fertile age who have menorrhagia. The subject's own assessment of the amount of menstrual blood loss does not generally reflect the true amount. All patients should undergo a pelvic examination and, if the menstrual pattern has changed substantially or if anaemia is present, a vaginal sonography should be carried out as the most important supplemental examination. Vaginal sonography combined with an endometrial biopsy is a reliable method for diagnosing endometrial hyperplasia or carcinoma, but it is insufficient for diagnosing endometrial polyps and fibroids; these can be diagnosed more reliably by sonohysterography or hysteroscopy. Non-steroidal anti-inflammatory drugs and tranexamic acid reduce menstrual blood loss by 20-60%, and the effectiveness of a hormonal intrauterine system (IUS) is comparable with that of endometrial ablation or hysterectomy. Cyclic progestogens do not significantly reduce menstrual bleeding of women who ovulate. Treatment should be started with one of the drug therapies, i.e. the IUS, tranexamic acid, anti-inflammatory drugs, or oral contraceptive. Drug treatment should be used and evaluated before surgical interventions are considered. With an effective training and feedback system, it is possible to organise the diagnostics, medical treatment and follow-up of heavy menstrual bleeding in the primary health care setting or in outpatient clinics, which reduces the burden on specialist health care.
