Adult Neurogenesis in the Subventricular Zone of Patients with Huntington's and Parkinson's Diseases and following Long-Term Treatment with Deep Brain Stimulation.

Objective: Parkinson's and Huntington's diseases are characterized by progressive neuronal loss. Previous studies using human postmortem tissues have shown the impact of neurodegenerative disorders on adult neurogenesis. The extent to which adult neural stem cells are activated in the subventricular zone and whether therapeutic treatments such as deep brain stimulation promote adult neurogenesis remains unclear.

Resection of ruptured hepatic teratoma in an adult.

Introduction: Extragonadal locations of teratomas are uncommonly reported in the literature. Teratomas are neoplasms usually found in the gonadal organs: ovaries and testis. The majority of teratomas are found in the pediatric age group.

Trans-anal minimally invasive surgery: A new technique to avoid peritoneal entry.

Introduction: Transanal minimally invasive surgery (TAMIS) is a valuable surgical option for removal of rectal polyps and early rectal cancers. A potential complication of this technique is abdominal entry if the lesion is located above the peritoneal reflection. We present the first case series describing the use of a laparoscopic stapling device to remove a sessile lesion, and seal the resulting defect simultaneously with full thickness excision of the rectal lesion, avoiding abdominal entry.
