A randomised comparison of microwave endometrial ablation with transcervical resection of the endometrium: follow up at a minimum of 10 years

Objective  To compare outcomes and further operations at a minimum of 10 years following microwave endometrial ablation (MEA^TM) or transcervical resection of the endometrium (TCRE).
Design  Follow up of a randomised controlled trial using postal questionnaires and operative databank review.
Setting  Gynaecology department of a large UK teaching hospital.
Main outcome measures  Women's satisfaction with treatment, menstrual symptoms, changes in health-related quality of life, and additional treatments received.
Results  One-hundred and eighty-nine of the original 263 women returned questionnaires (72%) after a minimum of 10 years post-treatment. Those totally or generally satisfied with treatment numbered 77/129 (60%) in the microwave arm and 70/134 (52%) in the resection arm, the difference is not statistically significant. Bleeding and pain scores were highly significantly reduced and similar following both MEA^TM and TCRE, achieving amenorrhoea rates of 83 and 88% respectively. The hysterectomy rate after 10 years was significantly different with 22 (17%) in the MEA^TM and 38 (28%) in the TCRE arm (95% CI: −0.21, −0.13).
Conclusions  Both techniques achieve significant and comparable improvements in menstrual symptoms, health-related quality of life and high rates of satisfaction. With the known operative advantages, lower costs and fewer hysterectomies, it is clear that MEA™ is a more effective and efficient treatment for heavy menstrual loss than TCRE.     

Neurosurgical anatomy of the anterior interhemispheric approach for aneurysms of the anterior communicating artery (26.6.92)

Summary The anterior interhemispheric approach for aneurysms of the anterior communicating artery was studied in ten cadavers. This approach presents several advantages over the pterional approach widely used in neurosurgery. It allows direct access to the region of the anterior communicating artery complex with minimal retraction of the brain and preservatioin of the olfactory tract and the gyrus rectus.

Bases anatomiques de l'abord inter-hémisphérique antérieur lors de la chirurgie des anévrysmes de l'artère communicante antérieure

Résumé Ce travail concerne l'abord neurochirurgical des anévrysmes de l'artére communicante antérieure par voie frontale interhémisphérique. L'étude anatomique a été réalisée sur dix sujets. Cette exposition possède de nombreux avantages comparée à la voie ptérionale habituelle : voie d'abord reduite médiane permettant une visualisation directe et symétrique du complexe artériel de l'artére communicante antérieure ; avec le moindre manipulation et retraction du cerveau en respectant les voies olfactives et le gyrus rectus.

     

Obstetricians and maternal body weight and eating disorders during pregnancy

Intrauterine growth restriction (IUGR) is associated with maternal prepregnancy body mass index (BMI), body weight gain during pregnancy and smoking, eating and weight-losing behaviors. The aim of this pilot study was to examine the practices of obstetricians to determine whether more can be done to prevent IUGR and 'do no harm' to the body image of women during pregnancy. Obstetricians (n = 67) who reported delivering an average of 125 babies in the previous year completed a questionnaire that enquired about their antenatal practice of maternal weighing, history taking and referral of pregnant women. No doctor calculated the prepregnancy BMI. Women (90%) were weighed during some or all antenatal visits, usually by the nurse-receptionist, but one-third of the obstetricians did not refer to these body weight records. Most obstetricians asked women about their cigarette smoking and alcohol intake before pregnancy, and during pregnancy discussed supplements and nausea and vomiting. Fewer than 50% of doctors asked about depression, body weight control and disordered eating. One-third of doctors were not aware of having seen a woman with an eating disorder in the previous year. Obstetricians who asked about eating disorders were more likely to ask about depression, and obstetricians in private practice were significantly less likely to ask women about a history of depression and to refer women to a psychologist or psychiatrist Obstetricians could improve antenatal care by asking about body weight and calculating prepregnancy BMI, and investigating weight-losing behavior and psychological or psychiatric problems such as eating disorders.     

Peripheral steroid levels in a patient with congenital absence of the uterus.

In a patient with congenital absence of the uterus, daily measurements of progesterone (P), 17-hydroxyprogesterone (17-P), pregnenolone (delta5P), 17-hydroxypregnenolone (17-delta5P), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), testosterone (T), dihydrotestosterone (DHT), androstenedione (A), estrone (E1), estradiol-17beta (E2), and cortisol (F) were performed over a period of 48 consecutive days. Serum P, 17-P, and E2 determinations revealed normal, cyclical ovarian activity consisting of two luteal phases and one follicular phase. Serum E1, delta5P, and DHEA-S levels were normal throughout the study, whereas DHEA and DHT levels were persistently elevated. Serum levels of 17-delta5P and A showed peak levels above normal. Serum T and F concentrations were normal during the initial part of the study, but some elevation was seen during the second luteal phase. In the patient studied, absence of the uterus did not seem to interfere with cyclic ovarian activity. The role of the uterus in the metabolism of androgens remains subject to further investigation.     

Addressing HIPAA across the continuum

HIPAA is an issue in hospitals across the nation, but what about other kinds of facilities--such as long-term care, behavioral health, or home care organizations? They, too, need to address HIPAA. We asked three HIM professionals who work in these settings to briefly address how HIPAA is changing the way they work.     

Vaginal reflux during miction-cystourethrography in girls (author's transl)

The cases of 57 girls with reflux of radioopaque iodin solution into the vagina during mictioncystourethrography are reported. In 52.6% (30 cases) no signs of anomalies of the urinary tract or of pyelonephritis were found. For this group of 30 girls pyuria (leucocyturia) was typical (in 86.6%). In contrast, a urinarty-tract infection was found only in a few cases (16.6%). The authors discuss the clinical importance of vaginal reflux and its role in the pathogenesis of urinary-tract infections.     

1,25-dihydroxycholecalciferol in renal osteodystrophy. Epiphysiolysis--anticonvulsant therapy

Three children with azotaemic renal osteodystrophy were treated with 1,25-dihydroxycholecalciferol (1,25(OH)2D3). All showed clinical, biochemical, and radiological improvement within 6 months of starting treatment. There were no complications. The dose of 1,25(OH)2D3 required was 0-5 microgram per day for 2 children aged 22 and 30 months, and 2 microgram per day for a 15-year-old boy. 2 of the patients were receiving phenobarbitone and phenytoin and in one of them prior treatment with dihydrotachysterol 0-5 mg daily and 6 microgram 1alpha-hydroxycholecalciferol (1alphaOHD3) daily had failed to induce improvement. In one patient, in whom serial iliac bone samples were available, 2 microgram 1,25(OH)2D3 resulted in histological improvement in previously severe osteomalacia. 1,25(OH)2D3 appears to be an effective and safe drug in the treatment of uraemic osteodystrophy.     

Postmenopausal steroid replacement with micronized dehydroepiandrosterone: preliminary oral bioavailability and dose proportionality studies.

OBJECTIVES: Because dehydroepiandrosterone may protect against neoplasia, osteoporosis, and cardiac disease, we investigated the bioavailability of oral micronized dehydroepiandrosterone, anticipating its adjunctive use in postmenopausal steroid replacement. STUDY DESIGN: Eight postmenopausal women randomly received either a placebo or 150 or 300 mg of oral micronized dehydroepiandrosterone in a lipid matrix. Serum dehydroepiandrosterone, dehydroepiandrosterone sulfate, testosterone, and estradiol were measured periodically over the 12 hours after each dose. All treatments, all doses, and mean serum dehydroepiandrosterone, dehydroepiandrosterone sulfate, and testosterone were compared with analysis of variance for repeated measures and Newman-Keuls a posteriori test of statistical significance. RESULTS: Mean peak steroid concentrations after 150 mg (300 mg) doses were dehydroepiandrosterone 1617 (2639) ng/dl, 7 (11.5)-fold above placebo; dehydroepiandrosterone S 1185 (1688) micrograms/dl, 14 (20)-fold above placebo; and testosterone 183 (311) ng/dl, 4 (7)-fold above placebo. Estradiol concentrations remained less than 20 pg/ml, but androgen concentrations rose by 1 hour and remained elevated through the twelfth hour. Peak androgen concentrations and areas under the curves exhibited proportionality with both doses. A testosterone radioimmunoassay with celite chromatography revealed a 300% overestimation for testosterone in the direct-assay method used in this study. Thus after appropriate readjustment maximum testosterone concentrations were observed consistently within physiologic premenopausal ranges after the 150 mg dose. CONCLUSIONS: Micronized dehydroepiandrosterone may provide a steroidal postmenopausal replacement that is adjunctive to estrogens and worthy of further investigation.
