High-grade poorly differentiated retroperitoneal sarcoma. Report of a case and review of the literature.

Retroperitoneal sarcomas (RPS) are uncommon tumors associated with a poor prognosis. This is particularly true in case of high-grade sarcomas of specific histological subtypes, as demonstrated by the largest surveys of the last decade. Up to the present day, unfortunately there are no powerful tools available except for surgery.

Laparoscopic repair of intraperitoneal bladder perforation due to indwelling urethral catheter.

Intraperitoneal perforation can occur as a rare but life threatening complication of indwelling urethral catheters. Computed tomography (CT) revealed the bladder perforation by the Foley catheter. The injury could not be managed conservatively due to the presence of systemic infection.

Is fixation during gastric banding necessary? A randomised clinical study.

Anterior fixation via a gastro-gastric suture in laparoscopic adjustable gastric banding (LAGB) is commonly performed to prevent band-related complications. However, the necessity of this common technique has never been proven. Not fixing the band would be time sparing and would reduce adhesions on the stomach and probably make revisional surgery easier.

Herniation of the gallbladder within a hernia of the abdominal wall associated with Mirizzi Syndrome.

A gallbladder incarcerated hernia associated with Mirizzi syndrome is a very rare entity and to our knowledge this is the first case ever described in literature. An 85-year-old man presented at the emergency department with a tender right upper quadrant mass. Computed Tomography (CT) revealed the presence of a gallbladder lithiasis with signs of acute cholecystitis, herniated through the abdominal wall with an associated Mirizzi syndrome.

Prediction of bone mass gain by bone turnover parameters after parathyroidectomy for primary hyperparathyroidism: neural network software statistical analysis.

Background: Primary hyperparathyroidism (pHPT) is the most frequent endocrine hypersecretion disease, and parathyroidectomy is the only curative option, since pharmacologic therapy reduces hypercalcemia but does not impede parathyroid hormone hypersecretion. According to guidelines from the National Institutes of Health, parathyroidectomy is associated with bone mass increase in some asymptomatic patients, while in others bone mass is not changed after surgery. Therefore, we performed the present study in an attempt to elucidate whether a preoperative biochemical bone parameter can be predictive of a significant vertebral bone mass increase in patients with pHPT.
