Multicenter Study Comparative Study
Asphyxia of the newborn in east, central and southern Africa.
Very scanty information is available in East, Central and Southern Africa on the incidence and risk factors associated with asphyxia of the newborn. A multicentre prospective study involving 4267 deliveries in eight countries was undertaken over a three month period, in maternity units of the central hospitals to determine the incidence; maternal, service and logistic risk factors for asphyxia of the newborn as determined by an abnormally low apgar score. 30% of births were by primigravida mothers, of whom 67% were teenagers. A birth by a teenager had a higher risk for low birth weight. ⋯ These should include identification of the at risk mother, proper referral and management while adhering to correct established procedures. There is also need to develop appropriate and relevant technologies for perinatal and neonatal care through research undertaken in the region. It is also concluded that the co-operation and joint effort between the obstetricians, paediatricians and the nursing staff who all contributed to the collection of this data is a cost effective approach to research in perinatal health and consequently in instituting interventions.

Multicenter StudyPreliminary report of unexpected local reactions to a progestogen-releasing contraceptive vaginal ring.
This is the first report of vaginal erythematous areas associated with the use of a levonorgestrel-releasing contraceptive ring. Of 139 female subjects, 48 developed lesions of varying size and degrees of redness. Sixteen of these have undergone serial colposcopy and thirteen have also had biopsy examinations, which revealed acetowhite areas and, histologically, chronic inflammation with widely dilated vessels and frequently with thinning of the epithelium. The cause remains uncertain but hormonal, chemical and physical effects might all have a role.

Randomized Controlled Trial Multicenter Study Clinical TrialGenital tract infections associated with the intrauterine contraceptive device can be reduced by inserting the threads into the uterine cavity.
To study the influence of the position of the threads of an intrauterine contraceptive device (IUCD) on the development of genital tract infection. ⋯ Infectious complications in women using an IUCD are more frequent if the threads lead from the uterine cavity to the vagina. This problem can be reduced by inserting the threads so that they remain entirely within the uterine cavity, a feasible procedure now that an effective instrument for IUCD thread retrieval is available.

Multicenter Study Comparative Study Clinical Trial Controlled Clinical TrialAn open study of Triphasil and Diane 50 in the treatment of acne.
Levonorgestrel, as used in oral contraceptives, has antiovulatory activity at doses far lower than those producing androgenic effects. Triphasil, containing levonorgestrel was compared with Diane, containing cyproterone acetate in a trial of acne treatment. Twenty closely matched patients were alternatively allocated to 6 months of Triphasil or Diane treatment. ⋯ Assays of total testosterone, androgen index, free testosterone, dehydroepiandrosterone sulphate and androstenedione showed significant reduction on treatment and sex hormone binding globulin was raised. All hormonal changes were more marked in the Diane group. Side effects caused only one withdrawal from the trial.
