Symptom-giving pelvic girdle relaxation in pregnancy. I: Prevalence and risk factors.

BACKGROUND: Previous studies concerning symptom-giving pelvic girdle relaxation in pregnancy have to our knowledge been retrospective. We wanted to 1) determine the incidence during pregnancy and the prevalence two, six, and twelve months post partum, 2) identify possible predisposing factors, and 3) determine the frequency and duration of sicklisting, prospectively. MATERIAL AND METHODS: A cohort of 1600 consecutive pregnant women filled in a questionnaire. At the routine prenatal examinations they were asked about pelvic pain. Those who fulfilled the inclusion criteria were examined by a rheumatologist to confirm the diagnosis. The affected women were seen again two, six, and twelve months post partum. All participants were asked about sicklisting in pregnancy. RESULTS: The incidence during pregnancy was 14%, the prevalence two, six, and twelve months post partum were 5%, 4%, and 2% respectively. Multivariate analysis indicates that the most important predisposing factor is pelvic pain in a previous pregnancy. Other factors were uncomfortable working conditions, lack of exercise, and previous low back pain and low abdominal pain. At least 37% of the women with symptom-giving pelvic girdle relaxation had been sicklisted in pregnancy due to pelvic pain, on average for twelve weeks. CONCLUSION: Symptom-giving pelvic girdle relaxation is a considerable problem both in pregnancy and post partum. The occupational risk can possibly be prevented. The syndrome has a great social impact because of the frequent sicklisting.

Symptom-giving pelvic girdle relaxation in pregnancy. II: Symptoms and clinical signs.

BACKGROUND: Pelvic pain in pregnancy appears to be a problem that is increasing. This study was undertaken to describe and analyze the relationship between subjective symptoms, daily disability, and clinical findings in women with symptom-giving pelvic girdle relaxation in pregnancy MATERIALS AND METHODS: Out of 1600 pregnant women 238 had pelvic pain. After a clinical examination 11 women were excluded due to low back pain. The rest, 227 women, was considered having symptom-giving pelvic girdle relaxation during pregnancy. RESULTS: Symptom-giving pelvic girdle relaxation in pregnancy seriously interferes with many activities of daily living such as housekeeping, walking, working, and sexual life. The women's statements of pelvic pain are well correlated to the number of positive clinical tests. CONCLUSION: Symptom-giving pelvic girdle relaxation in pregnancy causes considerable disabilities concerning daily activities.

[Birth statistics for "standard populations". A basis for obstetric quality development].

Using standard populations like "standard-primipara" (normal pregnancy, singleton term delivery and cephalic presentation) and "caesarean secundapara" (previous caesarean section and second birth) as the basis for interunit comparisons of maternity care will control for differences in casemix that may be seen at different units, thereby increasing the validity of comparisons. Focusing on clinically meaningful subsets of the population may have the additional benefit of clarifying the relationship between everyday clinical decision making, and the statistics from medical birth registration. Birth registry data from Rigshospitalet, Hvidovre Hospital and Herning Centralsygehus 1993-1994 have been used to illustrate the association between local quality improvement activities, on the one hand, and rates of interventions and foetal outcome in "standard-primipara" on the other.

Relaxin is not related to symptom-giving pelvic girdle relaxation in pregnant women.

BACKGROUND: The pregnancy associated hormone relaxin induces loosening of the pelvic ligaments in several species. This study was undertaken to evaluate whether pregnant women with symptom-giving girdle relaxation had increased serum relaxin concentrations during pregnancy. METHOD: Serum relaxin concentrations were measured in 38 pregnant women with symptom-giving pelvic girdle relaxation at the time of diagnosis, in the 30th and 38th week of pregnancy as well as 2 and 6 months after delivery. Fourteen pregnant women without symptoms served as a control group. Relaxin concentrations were measured by a homologous enzyme linked immuno-sorbent assay. All participants were clinically examined including tests for symptom-giving pelvic girdle relaxation. RESULTS: No differences in serum relaxin concentrations were found throughout pregnancy and after delivery. CONCLUSION: The present results do not suggest an important role for relaxin in symptom-giving pelvic girdle relaxation during human pregnancy.

A randomised controlled trial of prophylaxis of post-abortal infection: ceftriaxone versus placebo.

OBJECTIVE: To investigate the incidence of post-operative infection after first trimester abortion in women treated with a long-acting cephalosporin (ceftriaxone) compared with low risk patients receiving no treatment and with high risk patients receiving our standard treatment of ampicillin/pivampicillin and metronidazole. DESIGN: A prospective, randomised controlled trial. SETTING: Department of Obstetrics and Gynaecology, Rigshospitalet, University of Copenhagen, Denmark. SUBJECTS: Nine hundred and ninety-six women, admitted on an outpatient basis for legal termination of pregnancy at 12 weeks or less of gestation, were included in the study after giving informed consent. The women were divided into high risk and low risk categories and allocated either to treatment with ceftriaxone or to standard treatment. For high risk patients the standard treatment was initiated by a peroperative injection of ampicillin and metronidazole, followed by oral doses of metronidazole and pivampicillin three times daily for four days. No prophylactic antibiotics were given to the women randomised to standard treatment in the low risk group. INTERVENTIONS: All women were kept under observation, and, between six and 14 days postoperatively, underwent pelvic examination. Clinical endpoints were noted. MAIN OUTCOME MEASURES: Post-operative pelvic inflammatory disease in women applying for legal first trimester abortion. RESULTS: Seven hundred and eighty-six women fulfilled the criteria for evaluation. A tendency toward a prophylactic effect of ceftriaxone was observed in most clinical findings. A significant prophylactic effect of ceftriaxone was found in the low risk group. CONCLUSIONS: This study demonstrated a significant reduction in post-operative pelvic inflammatory disease in low risk patients, who were applying for legal first trimester abortion, treated peroperatively with ceftriaxone. No significant difference was demonstrated between high risk patients treated with ceftriaxone or ampicillin/pivampicillin and metronidazole.

The influence of nitrous oxide on recovery of bowel function after abdominal hysterectomy.

The influence of nitrous oxide on the recovery of bowel function was studied in 36 patients anaesthetised for elective abdominal hysterectomy with or without salpingo-oophorectomy. Patients were randomly assigned to receive either isoflurane in nitrous oxide and 30% oxygen (N2O group) or isoflurane in air and 30% oxygen (Air group). Anaesthetic management included thiopentone, fentanyl, suxamethonium and atracurium. The lungs were not ventilated prior to intubation. Before closing the abdomen, the surgeon assessed the degree of distension of the intestines and the closing conditions. Postoperative nausea and vomiting was assessed 2, 6, 12 and 24 h after recovery from anaesthesia. The lapse of time before mobilisation and passing of flatus and faeces was recorded. The patients in the Air group were significantly older than the patients in the N2O group (48.9 years versus 44.0 years, P = 0.04); otherwise, there were no differences in the demographic data of the patients. We found no significant differences between the groups with respect to nausea and vomiting, distension of the intestines before closure of the abdomen, closing conditions, time elapsing before mobilisation, constipation before recovery of bowel function or time elapsing before passing of flatus. We found a statistically significant delay of 10.3 h in time elapsing before passing of faeces in the N2O group compared to the Air group (P = 0.04), suggesting a potentially adverse effect of nitrous oxide.(ABSTRACT TRUNCATED AT 250 WORDS)

Malignant giant cell tumour of the uterus.

Two rare cases of malignant giant cell tumours of the uterus in pure heterologous form are presented. Light microscopy showed numerous osteoclast-like cells in a background of spindle cells. Immunohistochemistry demonstrated Vimentin, Actin, alpha-1-antitrypsin and LCA in the latter, and Vimentin, alpha-1-antitrypsin and LCA in the giant cells while tartrate resistant acid phosphatase reactivity was demonstrated in both mononuclear cells and giant cells. Electron microscopy did not reveal smooth muscle or epithelial differentiation. The findings suggest a common origin of malignant giant cell tumours and malignant fibrous histiocytomas.

Endocrine, metabolic and cardiovascular responses to adrenaline after abdominal surgery.

Adrenaline-induced changes in heart rate, blood pressure, plasma adrenaline and noradrenaline, cortisol, glucagon, insulin, cAMP, glucose lactate, glycerol and beta-hydroxybutyrate were studied preoperatively and 4 and 24 h after skin incision in 8 patients undergoing elective cholecystectomy. Late postoperative responses of blood glucose, plasma cAMP, lactate and glycerol to adrenaline infusion were reduced, whereas other responses were unaffected. Blood glucose appearance and disappearance rate as assessed by [3H]3-glucose infusion was unchanged pre- and postoperatively. The increase in glucose appearance rate following adrenaline was similar pre- and postoperatively. These findings suggest that several beta-receptor-mediated responses to adrenaline are reduced after abdominal surgery.

[Effect of posture on the diuretic treatment of decompensated cirrhosis and heart failure].

The diuretic effect of the supine position was evaluated in six patients with cirrhosis and ascites and six with congestive cardiac failure. All patients received 1 mg bumethanide intravenously and were randomly assigned to either bed rest in the supine position or normal daily activity in the upright position for the next six hours. The diuretic response was similar in patients with heart failure and cirrhosis, and was significantly greater in the supine than in the upright position: mean 1,133 v 626 ml/6 h (p less than 0.01). The natriuresis was similarly greater during recumbency: mean sodium 96 v 45 mmol (mEq)/6 h (p less than 0.01), and the excreted potassium in six hours was similar in both postures. The glomerular filtration rate was 100 and 66 ml/min (p less than 0.01) and the heart rate 76 and 83 beats/min (p less than 0.05) in the supine and upright positions, respectively. Plasma concentrations of noradrenaline, renin, and aldosterone rose significantly during the upright position. The results suggest that the attenuated response to intravenous bumethanide in the upright position and during normal daily activity may be due to the activation of several, homoeostatic mechanisms which may reduce the excretion of water and salt.

Removing a retained placenta by oxytocin--a controlled study.

No increase in maternal plasma oxytocin concentration was detected after administration of 100 IU oxytocin into the umbilical veins of seven women immediately after delivery. The delivery of the placenta was accelerated after umbilical vein injection of 100 IU oxytocin in a placebo-controlled study of 40 women: 12 minutes (4 to 40) in the oxytocin group versus 40 minutes (29 to 40) in the placebo group (median and interquartile ranges), p less than 0.05.
