Ectopic parathyroid adenoma located inside the hypoglossal nerve.

Background: Intraneural parathyroid adenomas are extremely rare, with only 9 cases of intravagal adenomas reported. We report the first case of an ectopic parathyroid adenoma located within the hypoglossal nerve.

Methods And Results: A 62-year-old woman presented with a palpable nodule in the right submandibular area, reduced bone mass, and elevated calcium and parathormone levels.

A rare case of malignant triton tumor with pluridirectional differentiation.

An enlarging soft tissue mass was resected from the leg of a young man with neurofibromatosis type 1. Rhabdomyosarcomatous elements admixed with islands of osteoid and chondroid matrix was seen on microscopy. Based on immunohistochemistry, a malignant triton tumor, an uncommon subtype of peripheral nerve sheath tumor with rhabdomyosarcomatous elements, was diagnosed.

Retroperitoneal, mediastinal, and subcutaneous emphysema, complicating colonoscopy and rectal polypectomy.

Complications of flexible endoscopy-though still rare-are increasing in frequency lately as more invasive procedures are routinely performed. Perforation, hemorrhage, coagulation disorders, thrombophlebitis, and splenic rupture have all been reported to complicate colonoscopy and colorectal polypectomies. In this paper, we report on a case of retroperitoneal, mediastinal, and neck surgical emphysema, complicating colonoscopy and rectal polypectomy, presented initially as a change in the voice and facial swelling.

The effect of capecitabine on the healing of colonic anastomoses in rats.

Purpose: Capecitabine is a fluoropyrimidine carbamate with antineoplasmatic activity, recommended for the treatment of colorectal cancer. This study was designed to assess the effectiveness of the perioperative administration of capecitabine on the healing process of colonic anastomosis.

Methods: Sixty Wistar rats were used, which were randomized in 2 groups of 30 each.

Efficacy and safety of ultrasonically activated shears in thyroid surgery.

Background: The purpose of this prospective study is to evaluate the efficacy of ultrasonically activated shears (UAS) in hemostasis as well as its safety in regard to complications in thyroid surgery.

Methods: Three hundred patients who had undergone surgery on the thyroid gland were divided into 2 groups of 150 patients each. Hemostasis as well as division of blood vessels and thyroid tissue were performed with the use of UAS in the first group and by conventional ligations in the second group.

Bone mass, gonadal function and biochemical assessment in young men with trisomy 21.

Objective: The objective of the study was to find out whether biochemical and hormonal profile of sexual function and mineral metabolism are related to low bone mass in young men with Down syndrome.

Study Design: Eleven young men with trisomy 21 (mean age 26.45 years) and 12 healthy university students of similar age, participated in the study.
