Oral contraceptive pills decrease pulmonary airway resistance in healthy north Indian women.

Objectives: Oral contraceptive pills (OCPs) are hormonal pills used by females to prevent conception; they are a combination of estrogen and progestin. There is, however, compelling evidence that throughout the reproductive life of a woman, her airways are subject to the influence of the cyclical variations in sex hormones which occur in relation to circadian rhythms. The present study has been designed to investigate the effects of OCPs on airway resistance in terms of spirometric parameters in OCP users and nonusers. Materials and Methods: A total of 100 women (age: 20-40 years) ware selected for the present study. The subjects were provided with a one-month supply of OCPs. The constituents per tablet of MALA-N used were levonorgestrel 0.15 mg and ethinylestradiol 0.03 mg. Peak expiratory flow rate (PEFR), forced expiratory flow in expiring 25-75% air (FEF 25-75), forced expiratory volume percentage in one second (FEV1% or FEV1/FVC), forced vital capacity (FVC), and forced expiratory volume in one second (FEV1) were recorded. Results: In our study, the FEF 25-75and PEFR increased significantly in OCP users, showing that these hormone pills decrease the resistance offered by small bronchioles.

Contracepción de emergencia con Levonorgestrel / Emergency contraception with levonorgestrel

La contracepción de emergencia puede evitar el embarazo luego de un coito sin medidas contraceptivas o cuando éstas fallan. Se recomienda el levonorgestrel, un gestágeno sintético, en dosis única de 1.5 mg (alternativamente en dos dosis de 0.75 mg espaciadas 12 h). Su eficacia es moderada, pues impide aproximadamente 80% de los embarazos. La eficacia es mayor cuanto más precozmente se administre, pero puede darse hasta 5 días post-coito. La tolerancia es similar o superior a la de otros preparados empleados con igual propósito. Los efectos adversos comprenden náuseas, vómitos, cefalea, tensión mamaria y alteraciones transitorias en la siguiente menstruación. Se desconoce si el levonorgestrel aumenta la probabilidad de embarazo ectópico cuando el tratamiento fracasa. No se recomienda su empleo como contraceptivo habitual. Cuando se administra antes del pico preovulatorio de LH, el levonorgestrel generalmente bloquea o retrasa la ovulación. Puede asimismo afectar la migración de los espermatozoides en el tracto genital femenino e, indirectamente, la fertilización. Pese a haberse postulado reiteradamente, no existe evidencia de un efecto antiimplantatorio. El conocimiento del método es muy variable en diferentes sociedades, pero aun donde es bien conocido permanece subutilizado. Se ha propuesto proveer levonorgestrel por adelantado para promover su uso. En ensayos clínicos, tal provisión no afectó adversamente el comportamiento sexual ni el empleo de otros contraceptivos, pero tampoco redujo el número de embarazos o abortos. En consecuencia, el empleo de levonorgestrel debe considerarse un método de respaldo que no reemplaza el uso de contraceptivos más eficaces.

Emergency contraception may avoid pregnancy after unprotected intercourse or when regular contraceptive measures fail. Levonorgestrel, a synthetic gestagen, is recommended for emergency contraception as a single 1.5-mg dose or, alternatively, two 0.75-mg doses taken 12 h apart. Its efficacy is moderate, preventing about 80% of pregnancies. Efficacy is higher the earlier after unprotected intercourse the drug is taken, but it may be administered up to 5 days post-coitum. Tolerance is similar to, or better than, those of other oral emergency contraceptives. Adverse effects include nausea, vomiting, headache, breast tenderness and transient alteration of menstrual bleeding pattern. It is not known whether levonogestrel increases the risk of ectopic pregnancy when the treatment fails. Its use as an ongoing contraceptive method is discouraged. When given before the preovulatory LH peak, levonorgestrel blocks or delays ovulation. It may also affect sperm migration in the female reproductive tract and have an effect on fertilization. Although it has been often postulated, there is no evidence for an anti-implantatory effect. Acquaintance with the method is quite variable among different societies, but it remains underutilized even where it is well known. Advance provision of the drug has been proposed as a way to promote its use. In clinical trials, advance provision did not adversely modify sexual or regular contraceptive behavior, but it did not reduce pregnancy or abortion rate either. Therefore, emergency contraception with levonorgestrel should be regarded as a backup method which is not a substitute for the continued use of more effective contraceptive methods.

The use of levonorgestrel - IUD in the treatment of uterine myoma in Thai women.

OBJECTIVE: This study was designed to evaluate the potential usefulness of the levonorgestrel-releasing intrauterine device (LNG - IUD ; Mirena) in treating women with uterine myomas. DESIGN: Prospective before-and-after (comparing) study. SETTING: Department of Obstetrics and Gynecology King Chulalongkorn Memorial Hospital. SUBJECTS: Sixteen women with uterine myomas who intended to receive treatment with the LNG IUD. INTERVENTION(S): Clinical and ultrasound examinations were performed prior to and at 1, 3 and 6 months after the LNG IUD insertion. MAIN OUTCOME MEASURES: Myoma and Uterine volume, menstrual blood loss assessed with pictorial blood loss assessment charts and hematocrit. RESULTS: Use of the LNG IUD was associated with a statistically significant reduction in the total myoma volume, average uterine size and marked reduction in menstrual blood loss. After 6 months of use, the median total myoma volume decreased from 19.82 mL to 11.63 mL (p < 0.05), median pictorial blood loss assessment chart score declined from 89 to 3 (p < 0.05). Hematocrit level increased over 6 months of use. The most common side effects were bleeding disturbances (68.8%). No pregnancies occurred during the study. CONCLUSION: The LNG IUD was associated with a profound reduction in myoma and uterine volume. For women with myomas of this size, the LNG IUD provides effective medical treatment of bleeding.

Contraception continuation rates and reasons for discontinuation in Zahedan, Islamic Republic of Iran

We evaluated contraception continuation rates and discontinuation reasons in Zahedan among 1741 women from 1998-2000. By Kaplan-Meier technique continuation rates were 92% for low dose combined hormonal oral contraceptives [OC], 86% for a levonorgestrel-releasing implant, 82% for intrauterine devices [IUD] and 53% for medroxyprogesterone acetate at the first year. After 3 years, continuation was 78% for levonorgestrel implant, 70% for OC, 60% for IUD and 44% for medroxyprogesterone acetate. The commonest reason for discontinuing OC and medroxyprogesterone acetate was changing method; for IUD and levonorgestrel-releasing implant, the commonest reason was side-effects. By Cox regression model, continuation rate and contraceptive type were significantly related to health centre

Effect of oral contraceptives on respiratory function.

The present study was carried out to assess the lung functions in oral contraceptive administered women. Lung function tests were carried out with Spirometer (Vitallograph Compact II). A significant increase in vital capacity (VC) was observed in these women as compared to normal control. There was also a significant decrease in forced expiratory volume in 1 sec./vital capacity (FEV1/VC%) and forced expiratory volume in 1 sec./forced vital capacity (FEV1/FVC%) among oral contraceptive administered women as compared to controls. Further, a significant increase in peak expiratory flow rate (PEF), reduction in forced expiratory flow rate (FEF75-85%) and FEF75% were observed among oral contraceptive administered women as compared to controls. The increase in VC and PEF might be due to the synthetic form of progesterone (progestins) present in oral contraceptive pills which causes hyperventilatory changes. Synthetic progesterone during luteal phase of menstrual cycle might increase the static and dynamic volumes of lung i.e. VC and PEF. But FEF75% showed a decrease which might be due to the lower neuromuscular coordination during breathing.

Eficácia, tolerabilidade, controle de ciclo e bem-estar em mulheres acima de 35 anos utilizando um contraceptivo de baixa dose contendo gestodeno e etinilestradiol (Harmonet) / Efficacy, tolerability, cycle control and welfare in woman above 35 years using a low dose contraceptive containing gestodene and ethynilestradiol (Harmonet)

Um estudo multicêntrico foi conduzido em 14 centros brasileiros para avaliar a eficácia, tolerabilidade, controle de ciclo e bem-estar em mulheres, não fumantes, acima de 35 anos utilizando um contraceptivo de baixa dose contendo gestodeno e etinilestradiol, durante seis ciclos de tratamento. Participaram do estudo 180 mulheres na faixa etária de 35 a 47 anos, das quais 158 (87,8 por cento) completaram os seis ciclos de tratamento. Nenhuma gravidez ocorreu entre as usuárias do contraceptivo em estudo. Um total de 950 ciclos foi avaliado. Em 92,5 por cento dos ciclos não houve spotting nem sangramento de escape. Ocorreu spotting em 7,2 por cento dos ciclos e sangramento de escape em 0,3 por cento dos ciclos. Com relação ao número de mulheres, 82,2 por cento não apresentaram spotting nem sangramento de escape em nenhum momento do ciclo. Observou-se uma diminuição significativa, indicativa de melhora, com relação ao pré-tratamento, nos escores do questionário de Moos de desconforto menstrual relativos a dor, concentração, mudanças comportamentais, afeto negativo, reações autonômicas, retenção hídrica e controle. Não houve alterações clinicamente significativas de peso, pressão arterial nem resultados laboratoriais. A adesão ao tratamento foi boa, tendo havido esquecimento de tomada de uma ou mais pílulas em apenas 3 por cento do total de ciclos; 12,2 por cento das mulheres não completaram o período de seis ciclos de tratamento, sendo que em 1,1 por cento dos casos a razão para descontinuação foi atribuída a efeitos adversos. Os resultados permitem concluir pela eficácia contraceptiva, bom controle de ciclo, tolerabilidade e bem-estar associados ao uso do contraceptivo de baixa dose contendo gestodeno e etinilestradiol em mulheres acima de 35 anos.

Effects of long-term treatment with depot medroxy progesterone acetate for contraception on estrogenic activity.

The aims of this study were to evaluate the serum estradiol level and the estrogenic activity in long-term DMPA users. From 1st January 1996 to 31st December 1996, fifty healthy women receiving DMPA for contraception for more than 36 months were recruited to the study. From the study, it was found that the mean duration of DMPA use was 59.1 +/- 30.7 months, the mean serum estradiol was 52.7 +/- 15.1 pg/ml and these women did not have problems of estrogen deficiency. This study revealed that long-term treatment with DMPA should not have any adverse effects on estrogenic activity.

Avaliação da tolerabilidade e do controle de ciclo de dois contraceptivos orais de baixa dose: estudo comparativo aberto / Assessment of the tolerability and cycle control of two low-dose oral contraceptives: an open-label study

Realizou-se um estudo aberto comparativo em nove centros brasileiros para avaliar a tolerabilidade e o controle de ciclo obtido com o uso de dois contraceptivos orais de baixa dose contendo 20 mg etinilestradiol/75 mg gestodeno e 20 mg etinilestradiol/150 mg desogestrel, durante seis ciclos de tratamento. Foram selecionadas 167 mulheres saudáveis com vida sexual ativa (77 no grupo do gestodeno e 90 no grupo do desogestrel), das quais 138 completaram os seis ciclos de tratamento. Em um subgrupo de novas usuárias realizou-se também perfil lipídico e hemostático. Foram avaliados 867 diclos no total. Ocorreu sangramento irregular em 4,6 por cento dos ciclos com gestodeno e em 8,1 por cento com desogestrel. A tolerabilidade a ambas preparações foi boa, mas houve significativamente mais náusea no grupo do desogestrel. O controle de ciclo foi bom com os dois contraceptivos, sendo que houve freqüência significativamente menor de sangramento irregular no grupo do gestodeno quando se leva em conta que todos os ciclos foram considerados. Não houve alterações clinicamente significativas no perfil hemostático. O perfil lipídico mostrou tendência a tornar-se mais favorável após seis ciclos de tratamento com as duas preparações. Não ocorreu alteração no peso médio das mulheres no grupo do gestodeno; no grupo do desogestrel houve aumento significativo no peso médio de aproximadamente 1 Kg após seis meses de tratamento. A adesão ao tratamento foi boa com as duas preparações. Os resultados deste estudo mostram que preparações contendo baixa dose de gestodeno ou desogestrel associados a 20 mg de etinilestradiol são contraceptivos bem tolerados que permitem bom controle de ciclo, sem efeitos colaterais significantes.
