[Cytologic-colposcopic-histopathologic correlations in preinvasive cervical lesions and cervical Human Papillomavirus infections]. / Correlación cito-colposcópica-histopatológica de lesiones cervicales preinvasoras e infección cervical por virus del papiloma humano.

Cervico-uterine cancer is the most frequent gynecological neoplasia in Mexico and cervico-vaginal cytology is the most practical and dependable resource in lesions detection. During the last years precursory lesions detection (NIC and HPV infection) has increased. So, every patient presenting with an abnormal cytology should be included in an evaluation program, that includes a colposcopic study with biopsy of suspicious lesions, in order to know cellular abnormality degree, as these studies combination increases diagnosis certainty. Ninety three patients were evaluated by colposcopy, as the Papanicolaou showed abnormality ICN type in any degree or HPV infection data, during the first three years of the Unidad de Colposcopia de la Beneficiencia del Hospital ABC. In 49 patients histopathological study, was done. A correlation of all studies was carried out. There was a correlation cytology-histopathology of 59.18%; and colposcopy-histopathology of 89.79%. It was concluded that evaluation by cytology is insufficient to establish a final diagnosis and treatment, and that colposcopic study is fundamental in the evaluation of the patient with abnormal exfoliative cytology.

[Analysis of the predictive value of prolactin concentration in the umbilical cord as an evaluation parameter for respiratory insufficiency in the newborn]. / Análisis del valor predictivo de la concentración de prolactina en cordón umbilical como parámetro evaluatorio de la insuficiencia respiratoria del recién nacido.

In fetal pulmonary development several substances and hormones which directly participate, have been involved. One of these is prolactin, which by raising concentrations through a complex mechanism seems to participate in pulmonary maturation. Due to the importance of product's pulmonary maturity producing respiratory failures of the newborn, some progress has been made in opportune diagnosis, and mainly in prophylaxis of this condition. In this study, serum samples were taken from the umbilical chord to know perinatal evolution after analysis of the evolution of each of the 37 cases, the results corresponded to previous results as published in literature for different conditions as toxemia, diabetes mellitus or prematurity, as well as the relationship between hormonal serum concentrations, and gestational age and weight.

Diagnóstico temprano de embarazo heterotópico con viabilidad del producto intrauterino: informe de dos casos y revisión de la literatura / Early diagnosis of heterotopic pregnancy with viability of intrauterine product: presentation of two cases and literature review

El embarazo heterotópico, es decir, la coexistencia de embarazo intra y extrauterino es una entidad poco frecuente, de difícil diagnóstico preoperatorio y potencialmente peligroso para la madre y el embarazo intrauterino. Existen factores de riesgo que incrementan esta entidad por lo que debe de tenerse en cuenta si se emplean además técnicas en reproducción asistida. El empleo de la ultrasonografía y de la laparoscopia son fundamentales para su detección y de esta manera poder realizar un tratamiento oportuno. Se presentan dos casos de embarazo heterotópico con viabilidad de la gestación intrauterina
