Lateral abdominal wall hernias after coughing: a single center experience.

Purpose: Forceful coughing is assumed to be an uncommon etiology for lateral abdominal wall hernias. The literature regarding this topic is very limited and there is a lack of consensus in management, both operative and non-operative. We aim to report our center's experience in repair of lateral abdominal wall hernias secondary to vigorous coughing.

The Diagnostic Utility of Splenectomy in Idiopathic Splenomegaly.

Introduction: With increasing frequency, patients with idiopathic splenomegaly are referred to surgeons for splenectomy. We evaluated the diagnostic utility of splenectomy and feasibility of a minimally invasive approach in the face of idiopathic splenomegaly.

Methods: We retrospectively reviewed 68 patients who underwent splenectomy for idiopathic splenomegaly.

Adult males buffer the cortisol response of young guinea pigs: Changes with age, mediation by behavior, and comparison with prefrontal activity.

In the guinea pig, the presence of the mother buffers hypothalamic-pituitary-adrenal (HPA) responses of her young during exposure to a novel environment, and can do so even if she is anesthetized. In contrast, under comparable conditions other conspecifics (siblings, other adult females) are less effective or ineffective in doing so. However, we recently observed that an unfamiliar adult male reduced plasma cortisol elevations and increased Fos in the prefrontal cortex of preweaning pups exposed to a novel enclosure for 120min.
