ABSTRACT
La hemorragia obstétrica representa un desafío para el equipo médico, aportando con importante morbilidad y mortalidad a las pacientes embarazadas.El manejo adecuado, precoz y expedito beneficia el logro de resultados favorables para la madre e hijo; es por esto que debemos reconocer activamente aquellas pacientes en riesgo de presentar un sangrado obstétrico significativo.Presentamos el primer caso reportado en Chile de una paciente embarazada con mala inserción placentaria, sometida a cesárea y decómo se realizó el manejo del sangrado intraoperatorio, con énfasis en el uso de Cell Saver como técnica ahorradora de sangre.(AU)
Obstetric hemorrhage is a challenge for the medical team, contributing with significant morbidity and mortality to the pregnant patient.An appropriate, early, and expeditious management eases the achievement of favourable results for mother and son. We must recognizeactively those patients at risk of a significant obstetric bleeding.We present the first case report in Chile of a pregnant patient with abnormal placentation, undergoing a caesarean section and howbleeding was handled during the surgery, with emphasis on the use of a Cell Saver device as a blood-saving technique.(AU)

Background: Molecular techniques for human papillomavirus (HPV) detection have a good performance as screening tests and could be included in cervical cancer early detection programs. We conducted a population-based trial comparing HPV detection and Papanicolaou as primary screening tests, in a public health service in Santiago, Chile. Aim: To describe the experience of implementing this new molecular test and present the main results of the study. Material and Methods: Women aged 25 to 64 enrolled in three public health centers were invited to participate. In all women, samples were collected for Papanicolaou and HPV DNA testing, and naked-eye visual inspection of the cervix with acetic acid was performed. Women with any positive screening test were referred to the local area hospital for diagnostic confirmation with colposcopy and biopsy of suspicious lesions. Results: Screening results were obtained for 8265 women, of whom 931 (11.3%) were positive to any test. The prevalence of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) was 1.1%; nine women had invasive cervical cancer. Sensitivities for the detection of CIN2+ were 22.1% (95% confidence interval (CI) 16.4-29.2) for Papanicolaou and 92.7% (95% CI 84.4-96.8) for HPV testing; specificities were 98.9% (95% CI 98.7-99.0) and 92.0% (95% CI 91.4-92.6) respectively. Conclusion: This experience showed that the implementation of a molecular test for cervical cancer screening is not a major challenge in Chile: it was well accepted by both the health team and the participants, and it may improve the effectiveness of the screening program.

Reportamos el caso de una mujer de 21 años con hiperandrogenismo rápidamente progresivo de origen tumoral ovárico. La biopsia informó tumor de células de la granulosa y la resección fue curativa. Se analizan los posibles mecanismos por los que un tumor de origen en células de la granulosa pueda sintetizar andrógenos.
We report a 21 year old woman with rapidly progressive hyperandrogenism of ovaric tumoral origin. The biopsy of the tumor reported a granulosa cell tumor and the surgery was curative. We analyze the possible mechanisms implied in the androgen production in the granulosa cells of the tumor.

Our laboratory has implemented an in vitro assay to estimate the response to chemotherapy in ovarian cancer cells pertaining to individual patients. In two selected patients, we determined the correlation between an in vitro assay of cells from suspected ovarian cancer ascites, with the clinical chemotherapy response. Cancer cells isolated from peritoneal fluid with suspected ovarian cancer were tested for cytotoxicity with corresponding chemotherapy regimens. Circulating Cal25 levels and attending physician consultation determined clinical course and response to chemotherapy. The in vitro assay result correlated with Cal25 levels, progression free survival and attending physician evaluation. The assay predicted correctly the failure of two successive chemotherapy regimes in the first patient, while predicting a favorable clinical response in the second subject.

Background: symptoms predominate. Diagnosis is based on clinical findings and appropriate imaging. We report two females, aged 35 and 51 years. One of them presented with a pelvic mass and dyspnea, the other patient had severe cardiac failure on admission. Computed axial tomography scan allowed an accurate preoperative diagnosis on both patients. Successful one stage resection of the tumor was performed under cardiopulmonary bypass. Both patients are asymptomatic on follow up at 6 months and 25 years.

Se analizan diferentes antecedentes clínicos (edad, paridad, edad de inicio de relaciones sexuales; síntomas, método anticonceptivo usado), en 402 pacientes con diagnóstico confirmado de Displasia Severa, cuyo seguimiento promedio es de cinco años. Se destaca la importancia de la Citología exfoliativa del cuello uterino, de la Biopsia dirigida por colposcopía, y el valor diagnóstico y terapéutico de la Conización del Cuello Uterino
