[Screening for symptoms of depression during postpartum and the long term follow up: temporal stability and associated factors].

Aims: To describe the frequency of depressive symptoms compatible with a postpartum depression diagnosis, the associated factors and the temporal stability.

Methods: During 2006-2007 398 hospitalized puerperal women who attended CEMIC were interviewed 5 days after childbirth using the Edinburgh Postnatal Depression Scale and a socio-demographic questionnaire. A logistic regression analysis was performed to identify associated factors with a positive screening.

Immunohistochemical characterization of neoplastic cells of breast origin.

Background: After skin cancer, breast cancer is the most common malignancy in women. Tumors of unknown origin account for 5-15% of malignant neoplasms, with 1.5% being breast cancer.

Sentinel lymph node molecular pathology in breast carcinoma.

Objectives: The prognosis of breast cancer patients depends on primary tumor resection and axillary lymph nodes examination. The purpose of this study was to analyze by molecular biology techniques the presence of mammaglobin A and B messenger RNA in breast sentinel lymph node (SLN) by reverse-transcription polymerase chain reaction (RT-PCR).

Methods: Sentinel lymph nodes from 50 patients with a diagnosis of breast cancer were prospectively studied between June 2004 and August 2006.
