Use of sibutramine to assist obese women with weight loss can be successful in dietitian-led clinics: another tool in the dietitian's toolbox.

BACKGROUND: This study investigated differences in weight loss outcomes in obese women with Type 2 diabetes (T2D) compared to those without T2D attending a 6-month dietetic led 'Lifestyle' intervention. In those who had failed to reach weight loss goals using the 'Lifestyle' approach, the study further examined the effect on weight loss with the addition of sibutramine (Reductil, Abbott Laboratories, USA) over a 6-month period. METHODS: The study comprised a case-control analysis of data from 38 obese female patients (18 with T2D) from the 'Lifestyle' and 'Pharmacotherapy' clinics attending a tertiary hospital in the UK. RESULTS: In the 'Lifestyle' treatment groups, those with T2D lost significantly less body weight than those without T2D [5.26 kg (4.54%) versus 9.89 kg (9.55%), respectively]. For subjects who had failed to lose weight via the 'Lifestyle' intervention, the addition of sibutramine resulted in a similar weight loss compared to their pair-matched 'Lifestyle' only 'successful' counterparts (9.66% versus 9.55%). CONCLUSIONS: Not all obese women, and those with T2D in particular, will derive benefit from 'Lifestyle' advice and those who are resistant to this treatment approach may be assisted by pharmacotherapy. Dietitians can play a role in identifying those individuals who may benefit from the use of pharmacotherapy.

The natural history of pelvic organ support in pregnancy.

Little is known about the anatomic and physiologic changes in the pelvic floor that occur during pregnancy. The purpose of this study was to prospectively document pelvic organ support throughout pregnancy using the standardized system of the International Continence Society, also known as the Pelvic Organ Prolapse Quantification (POPQ) Staging System. Pelvic organ support evaluations were performed in nulliparous pregnant women presenting for routine obstetric care during each trimester. POPQ stage assignments and POPQ component measurements were compared for first-, second- and third-trimester examinations. Overall POPQ stage was significantly higher in the third trimester than in the first (P=0.001). Individual POPQ points which showed significant differences between the first and third trimesters include Aa, PB, Ap, Ba, Bp, TVL and GH. These findings probably represent normal physiologic changes of the pelvic floor during pregnancy, but suggest that significant changes may be objectively demonstrated prior to delivery.

Oral misoprostol vs. intravaginal prostaglandin E2 for preinduction cervical ripening. A randomized trial.

OBJECTIVE: To compare orally administered misoprostol with intravaginal prostaglandin E2 for cervical ripening and labor induction. STUDY DESIGN: Patients presenting with medical or obstetric indications for labor induction whose Bishop's score was < or = 6 were randomly allocated to receive either 50 micrograms of oral misoprostol or 4 mg of intravaginal prostaglandin E2. If adequate cervical ripening (Bishop score of 9 or cervical dilatation of 3) or active labor did not ensue, repeat doses of each medication were administered every four hours. A maximum of six doses of either oral misoprostol or intravaginal prostaglandin E2 was permitted. Intravenous oxytocin was subsequently administered according to a standardized infusion protocol. RESULTS: Sixty patients were enrolled, with 29 randomized to the oral misoprostol arm and 31 to the prostaglandin E2 group. The data on 58 patients were eligible for analysis. Delivery occurred within 48 hours in 96.4% (27/28) of those administered oral misoprostol as compared to 76.7% (23/30) of those who received intravaginal prostaglandin E2 (P = .03). The mean time intervals from the start of induction to delivery were similar between the two groups (1,496 +/- 120 vs. 1,723 +/- 230 minutes, P = .40). No statistically significant differences existed between the two groups with respect to intrapartum complications, tachysystole, uterine hyperstimulation or adverse neonatal outcomes. CONCLUSION: Oral administration of misoprostol is an effective alternative to intravaginal prostaglandin E2 for preinduction cervical ripening.

The response of renal cortical adenine nucleotides to different flush-out solutions.

Changes in energy metabolism of canine renal cortex were investigated immediately after nephrectomy and following flushout with two solutions. Even a brief period of ischaemic produced a sharp fall in adenine nucleotide concentration: further fall was prevented by flushout with cold Ringer's solution and some restoration of nucleotides was achieved by flushing with a modified Collins' solution.
