Predictors of Length of Hospital Stay After Reduction of Internal Hernia in Patients With a History of Roux-en-Y Gastric Bypass.

Background: Postoperative internal hernias after Roux-en-Y gastric bypass (RYGB) have an incidence of 2%-9% and are a surgical emergency. Evidence on factors associated with length of stay (LOS) after emergent internal hernia reduction in RYGB patients is limited.

Methods: This is a retrospective review of patients who underwent internal hernia reduction after RYGB at our tertiary care center over a 5 year period from 2015 to 2020.

Complications 18 years after polyacrylamide hydrogel augmentation mammoplasty: a case report and histopathological analysis.

Polyacrylamide hydrogel (PAAG) is a synthetic substance previously used as an injectable material for augmentation mammoplasty. Current literature has demonstrated that the average time from PAAG injection to the onset of complication ranges from 6 to 39 months. We present a unique case report describing the onset of complications 18 years after PAAG augmentation mammoplasty.

A rare case of percutaneous endoscopic gastrostomy causing a small bowel obstruction and subsequent bowel erosion.

Gastrostomy tubes can be used to provide long-term nutrition and feeding when oral intake is not adequate. A rare but serious complication includes iatrogenic small bowel injury. The incidence of this is infrequent due to its position of the small bowel beneath the omentum, however, injury leading to obstruction and volvulus has been previously described in the literature.

Climatic Impact of Volcanic Eruptions.

Volcanic eruptions have the potential to force global climate, provided they are explosive enough to emit at least 1-5 megaton of sulfur gases into the stratosphere. The sulfuric acid produced during oxidation of these gases will both absorb and reflect incoming solar radiation, thus warming the stratosphere and cooling the Earth's surface. Maximum global cooling on the order of 0.
