Radiological approach to cavitary lung lesions.

Cavitary lesions in the lung are not an uncommon imaging encounter and carry a broad differential diagnosis that includes a wide range of pathological conditions from cancers, infections/inflammatory processes to traumatic and congenital lung abnormalities. In this review article, we describe a comprehensive approach for evaluation of cavitary lung lesions and discuss the differential diagnosis in the light of radiological findings.

Chronic pulmonary embolism: diagnosis.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a complication of venous thromboembolic disease. Differently from other causes of pulmonary hypertension, CTEPH is potentially curable with surgery (thromboendarterectomy) or balloon pulmonary angioplasty. Imaging plays a central role in CTEPH diagnosis.

Long-Term Response of Hirsutism and Other Hyperandrogenic Symptoms to Combination Therapy in Polycystic Ovary Syndrome.

Background: Polycystic ovary syndrome (PCOS) affects 5%-15% of women and is the most common cause of hirsutism. Data on the time-course of improvement to suppressive therapy and predictors of that response in PCOS are lacking. The objectives of our study are to determine the long-term response and identify predictors of response in PCOS women treated with suppressive therapy, including spironolactone (SPL) + oral contraceptives (OCs).

Perinatal outcomes after natural conception versus in vitro fertilization (IVF) in gestational surrogates: a model to evaluate IVF treatment versus maternal effects.

Objective: To study the perinatal outcomes between singleton live births achieved with the use of commissioned versus spontaneously conceived embryos carried by the same gestational surrogate.

Design: Retrospective cohort study.

Setting: Academic in vitro fertilization center.
