The oral contraceptive pill effectively permits cycle batching for an intermittent in vitro fertilization programme in Trinidad and Tobago / Las Píldoras Anticonceptivas Orales Permiten la Agrupación Eficaz de los Ciclos para un Programa Intermitente de FIV en Trinidad y Tobago

Assisted reproductive technology (ART) in small island states like Trinidad and Tobago is usually provided in batches so as to minimize the cost of providing the service. As a result, patients 'cycles have to be synchronized in order to coincide with the arrival of a visiting embryologist. This is a retrospective study which evaluates the experience of pre-treatment with an oral contraceptive pill (OCP) as a means of batching cycles for an intermittent ART programme. Seventy-four in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles in which OCP usage was employed (Group A), were compared with 121 cycles which did not require pharmaceutical manipulation (Group B). In both groups more than 50 of women were older than 36-years. Two cycles were cancelled in Group A and seven in Group B, because of poor ovarian response. Although the pregnancy rate per treatment cycle was higher in Group A than in Group B (26.3 vs 17.3), this difference was not significant. More spontaneous miscarriages occurred in the non-OCP women and ovarian cyst formation was more common in these women. The authors experience indicates that the OCP is a simple, cheap and efficient means of batching patients for an intermittent ART programme and can be utilized in other small ART centres

La tecnología de reproducción asistida (TRA) en los pequeños estados insulares como Trinidad y Tobago, usualmente se ofrece por tandas a fin de minimizar los costos del servicio brindado. En consecuencia, los ciclos de las pacientes tienen que ser sincronizados de modo que coincidan con la visita del embriólogo. Éste es un estudio retrospectivo que evalúa la experiencia del pretratamiento con píldoras anticonceptivas orales (PAO) como medio de agrupar los ciclos con el propósito de organizar un programa intermitente de TRA. Setenta y cuatro ciclos de fertilización in vitro (FIV) e inyección intracitoplasmática de esperma (ICSI) en los que se recurrió al uso de PAO (Grupo A), fueron comparados con 121 ciclos que no requirieron manipulación farmacéutica (Grupo B). En ambos grupos, > 50% de las mujeres tenían más de 36 años de edad. Dos ciclos fueron cancelados en el grupo A y siete en el grupo B, debido a una respuesta ovárica pobre. Aunque la tasa de embarazo por ciclo de tratamiento fue más alta en el grupo A que en el grupo B (26.3% vs. 17.3%), esta diferencia no fue significativa. El número de abortos espontáneos fue mayor y la formación de quistes ováricos más común, en las mujeres que tomaron PAO. La experiencia de los autores indica que la PAO es un medio simple, económico y eficaz de agrupar a los pacientes en un programa intermitente de TRA, y puede utilizarse en otros centros pequeños de TRA.

Sterization patterns in a maternity unit

An evaluation of the characteristics of 425 womwn on whom surgical sterilization were performed revealed that 40% were 35 years or older and 48% had 5 or more children. Thirty-five per cent were Roman Catholics, and there was an equal incidence among the two major ethnic groups of Trinidad. Parental desire was the chief indications for tubal ligation. Complications were few, regardless of the procedure. A plea is made for intensifying efforts in promoting postpartum sterilizations following vaginal delivery, particularly for mothers whose life circumstances would prohibit them from returning for interval sterilization

Re-evaluation of diagnostic uterine dilatation and curettage: a review of 203 patients

Two handred and three patients were reviewed to assess the efficacy of diagtnostic uterine dilatation and curettage. Thirteen (6.4%) had definitive pathological changes of the endometrium; of the 4 patients with endometrial carcinoma, 3 presented eith post-menopausal bleeding. Anaemia was present in 11/3% of those with menorrhagia. The complication rate was 3.4% and the mean hospital stay, 3 days. It is suggested that in pre-menopausal women with abnormal uterine bleeding, medical management and outpatient endometrial biopsy should be the preferred diagnostic approach. fora post-menopausal women, curettage under general anaethesia remains the diagnostic method of choice
