    Notes: Abstract Residues of dichlorodiphenyltrichloroethane (DDT) and its metabolites were monitored in leiomyomatous and normal human uterine tissue by gas-liquid chromatography (GLC). The metabolites detected were: 2,2-bis-(p-chlorophenyl)-1,1-dichloroethylene (p,p′-DDE), 2-(o-chlorophenyl)-2-(p-chlorophenyl)-1,1,1-trichloroethane (o,p′-DDT), 2,2-bis-(p-chlorophenyl)-1,1-dichloroethane (p,p′-DDD) and 2,2-bis-(p-chlorophenyl)-1,1,1-trichloroethane (p,p′-DDT). Total DDT ranged from 0.245 to 1.982 ppm, with a mean value of 0.845 ppm in leiomyomatous tissue. In normal human uterine tissue, total DDT ranged from 0.030 to 0.282 ppm, with a mean value of 0.103 ppm. Significantly higher levels of DDT and its metabolites in leiomyomatous tissue as compared to normal uterine tissue suggest their involvement in uterine leiomyomas. The data is discussed in the light of existing knowledge on estrogenic activity of DDT analogs and estrogeninfluenced growth of uterine leiomyomas.

    Description / Table of Contents: Resumé Deux études one été réalisées à l'AIIMS afin de déterminer l'efficacité, les effets secondaires et l'acceptabilité d'un anneau contraceptif au Silastic dont la partie centrale contenant 6,0 mg de lévonorgestrel mélangé au Silastic est enrobée de Silastic uniquement. Ce dispositif libère le lévonorgestrel en quantité constante de 20 μg par jour et reste efficace pendant 90 jours. La première étude, faite sur 50 femmes, a duré 12 mois et la seconde, avec 46 femmes, a été prolongée à 24 mois. L'abandon de cette méthode a été déterminé le plus souvent par des irrégularité menstruelles recontrées chez 36% des patientes. La plupart des femmes ont présenté des ménorragies ou des microrragies vaginales. On a constaté comme seconde raison la plus commune d'interruption l'irritation du vagin ou un écoulement vaginal accru chez 23% des intéressées, et des expulsions spontanées et répétées one provoqué l'abandon chez 6% des sujets. Aucun échec imputable à la méthode n'a été signalé au cours de ces études. Les visites de suivi ont révélé que les utilisatrices étaient plus satisfaites de cette méthode que de n'importe quelle autre et aucun partenaire ne s'est plaint de sentir l'anneau pendant le coït. Facilité de mise en place, absence d'effets secondaires gastro-intestinaux et pourcentage élevé de succès font espérer que pendant la dernière décennie du 20-ème siècle l'anneau vaginal s'avérera une méthode de contraception prometteuse.
    Abstract: Resumen Se realizaron dos estudios en AIIMS con el objeto de determinar la eficacia, los efectos secundarios y la aceptabilidad de un anillo anticonceptivo de silastic cuya parte central, que contenía 6.0 mg de levonorgestrel mezclado con el silastic, se hallaba rodeada de silastic únicamente. El dispositivo descarga levonorgestrel en una proporción constante de 20 μg diarios y tiene una eficacia de 90 días. El primer estudio, realizado con 50 mujeres, tuvo una duración de 12 meses y el segundo, con 46 mujeres, se prolongó a 24 meses. El abandono de este método fue determinado principalmente por irregularidades menstruales en el 36% de las pacientes. La mayoría de las mujeres experimentaron menorragia o microrragia vaginales. La segunda razón más común de interrupción fue la irritación de la vagina o un flujo mayor en el 23% de las mujeres, y expulsiones espontáneas y repetidas provocaron el abandono en el 6% de las pacientes. En el curso de este estudio no se observó ningún fracaso atribuible al método. Los estudios de seguimiento indicaron que las usuarias estaban más satisfechas con este método que con cualquier otro, y las parejas de estas mujeres no sintieron el anillo durante el coito. La facilidad de colocación, la ausencia de efectos secundarios gastrointestinales y el porcentaje elevado de éxito hacen esperar que durante la última década del siglo XX el anillo vaginal sea un método anticonceptivo prometedor.
    Notes: Abstract Two studies were carried out at AIIMS to judge efficacy, side-effects and acceptability of the contraceptive vaginal ring, a Silastic ring with an inner core containing 6.0 mg levonorgestrel mixed with Silastic and an outer core of Silastic only. It releases levonorgestrel at a constant rate of 20 μg/day and remains effective for 90 days. The first study of 50 women lasted for 12 months and the second study of 46 women lasted 24 months. Menstrual irregularity in 36% of women was the commonest reason for discontinuation. The majority of women experienced menorrhagia or irregular spotting per vaginum. Vaginal irritation or increased vaginal discharge was the second commonest reason for discontinuation and was noted in 23% of subjects. Repeated spontaneous expulsions accounted for discontinuation in 6% of subjects. No method-related failure was noted in the study. Follow-up study revealed users to be happier with the ring than with any other method and no spouse complained of feeling the ring during coitus. With its ease of administration, absence of gastrointestinal side-effects and a high success rate, the contraceptive vaginal ring is a promising contraceptive method for the last decade of the 20th century.

    Notes: Abstract The present study was conducted to compare the therapeutic regimens of low-dose mifepristone (200 mg) plus vaginal meteneprost versus oral misoprostol in terms of efficacy and safety for medical termination of early pregnancy. A randomized clinical trial was conducted by the Department of Obstetrics and Gynecology at the All India Institute of Medical Sciences, New Delhi. A total of 101 subjects were enrolled within 56 days of amenorrhea. A single dose of 200 mg of mifepristone (RU 486) was given and, 48 hr later, prostaglandin was administered as either 5 mg of 9-methylene PGE2 vaginal gel, meteneprost (classified as group I) or 600 μg of oral PGE1 derivative misoprostol (classified as group II). In group I, 50 subjects and in group II, 51 subjects were treated with the respective schedule. The success rate with mifepristone + misoprostol (group II) was 88.63% which was significantly higher than that with mifepristone + meteneprost (group I) which was 82% (p〈0.05). The average duration of bleeding in cases with complete abortion was 8.95±5.67 and 9.77±6.51 in group I and II, respectively. There were no serious side-effects. Only one subject in group I (2%) required blood transfusion for heavy bleeding. This study indicated that oral prostaglandin after a low dose of mifepristone (200 mg) could be developed into an effective method to terminate early pregnancy. Oral administration of both drugs would be a more convenient, feasible, private and acceptable regimen.
