Testosterone Therapy for Dropped Head Syndrome: A Case Report.

Dropped head syndrome (DHS) is an impairment of neck extension resulting in a chin-on-chest deformity. DHS is rarely seen but a major hindrance to daily function in affected patients. DHS has been associated with movement disorders, neuromuscular disorders, and electrolyte and endocrine abnormalities.

Near-Infrared Confocal Laser Reflectance Cytoarchitectural Imaging of the Substantia Nigra and Cerebellum in the Fresh Human Cadaver.

Background: Cytoarchitectural neuroimaging remains critical for diagnosis of many brain diseases. Fluorescent dye-enhanced, near-infrared confocal in situ cellular imaging of the brain has been reported. However, impermeability of the blood-brain barrier to most fluorescent dyes limits clinical utility of this modality.

Association between trauma and acute hemorrhage of cavernous malformations in children: report of 3 cases.

OBJECTIVE Cavernous hemangiomas are benign congenital vascular abnormalities. Intracerebral cavernous hemangiomas have an appreciable risk of spontaneous hemorrhage. Little is known as to whether head trauma increases the risk of bleeding for these lesions.

Toluene optic neurotoxicity: magnetic resonance imaging and pathologic features.

Toluene, a colorless liquid found in glues, paints, and industrial products, is lipid soluble and rapidly absorbed by the lipid-rich central nervous system. Prolonged exposure through occupation or purposeful inhalation may lead to neurologic abnormalities. Two men presented with multifocal central nervous system defects and bilateral optic neuropathy of unclear etiology.

Incidental finding of placental choriocarcinoma after an uncomplicated term pregnancy: a case report with review of the literature.

Choriocarcinoma is frequently preceded by a complete mole, ectopic pregnancy, nonmolar intrauterine abortion, and uncommonly by a partial mole. Choriocarcinoma coexisting with or after an otherwise "normal" pregnancy is extremely rare, with an estimated occurrence of 1 per 160,000 pregnancies. We here report a case of a placental choriocarcinoma with no metastases in a full-term intrauterine pregnancy.

Disseminated Prototheca wickerhamii infection with arthritis and tenosynovitis.

Achloric algae of the Prototheca species are a rare cause of infection in humans. These infections are usually localized to the skin, olecranon bursae, and tendon sheaths of the hands and wrists. Our patient with acquired immunodeficiency syndrome and a chronic Prototheca wickerhamii skin infection of the hand developed tenosynovitis and arthritis of his ankle in the setting of a documented algemia.
