Traumatic brain injury in a rural indigenous population in Canada: a community-based approach to surveillance.

Background: Indigenous populations are disproportionately affected by traumatic brain injury. These populations rely on large jurisdiction surveillance efforts to inform their prevention strategies, which may not address their needs. We examined the incidence and determinants of traumatic brain injury in an indigenous population in the Terres-Cries-de-la-Baie-James health region of the province of Quebec and compared them with the incidence and determinants in 2 neighbouring health regions and in the province overall.

Rare malignant neoplasm of the leg: diagnosis and management dilemma.

This case report highlights a rare, virulent, aggressive, poorly differentiated, epithelioid fibrosarcoma with numerous rhabdoid cells on the tibial aspect of an 84-year-old woman. Biopsy of the lesions were reviewed at College of Physicians and Surgeons of Columbia University Department of Dermatopathology (New York, New York) and in consultation with the Soft Tissue Pathology Division of the Surgical Pathology Department at Columbia University as well as the Department of Pathology at the Massachusetts General Hospital Division of Bone and Soft Tissue Pathology. The management of this patient was difficult especially considering her mental status.

Gougerot-Carteaud Syndrome Treated with 13-cis-retinoic Acid.

A 15-year-old Caucasian boy with a diagnosis of confluent and reticulated papillomatosis who had received numerous treatments with minimal responses cleared with a 20-week course of 13-cis-retinoic acid and has remained in remission. It is important to consider the use of oral retinoids in the treatment of this stubborn, unsightly, and psychologically upsetting disease.

Unusual documentation of the transformation of a nevus into malignant melanoma.

It is well documented that congenital nevi have a statistical chance of becoming malignant; however, it is unusual to actually follow the progression of such an event. A 48-year-old man photographically documented changes in his own nevus, which was present at birth, over a period of six months. Seeing this evolution in one lesion is interesting.
