Gastric diverticulum: "a wayside house of ill fame" with a laparoscopic solution.

Background: Gastric diverticulum (GD) is an extremely rare disorder that can easily be overlooked when investigating the cause of abdominal pain. Its diagnosis is founded on a history of gastrointestinal symptoms and a typically unrevealing physical examination, and diagnosis requires confirmation from UGI contrast studies, EGD, and CT scan. Symptomatic GD should be kept in consideration as a cause of abdominal issues, because not only is it treatable, but also complications of GD can be life threatening.

Simultaneous ipsilateral posterior knee and hip dislocations: case report, including a technique for closed reduction of the hip.

In isolation, dislocations of the hip and knee require emergent reduction to minimize the risks of serious complications, including vascular and neurologic injury, osteonecrosis of the femoral head, and loss of motion and function. With simultaneous dislocation of the ipsilateral hip and knee, as in the situation of hip dislocation with concomitant femoral shaft fracture, reduction of the hip may prove difficult because of the inability to control the femoral segment. In this setting, general anesthesia is commonly required.

Regeneration along intact nerves using nerve growth factor and ciliary neurotrophic factor.

The purpose of this investigation was to evaluate the ability of a specific growth factor combination, nerve growth factor (NGF) and ciliary neurotrophic factor (CNTF), to enhance peripheral nerve regeneration. Eight groups of eight Sprague-Dawley rats underwent repair of a nerve gap defect: Group A (immediate repair), Group B (intact nerve bridge), Group C (nerve autograft), Group D (gap in situ), Group E (NGF + CNTF), Group F (NGF), Group G (CNTF), and Group H (saline). Twelve weeks after surgery, analysis included the measurement of the isometric force of muscle contraction for the tibialis anterior muscle and tissue harvesting for both quantitative and qualitative analysis.
