OBJECTIVE The purpose of this study was to evaluate the diagnostic accuracies of 2 free thyroxine immunoassays during pregnancy. STUDY DESIGN Serum was collected from healthy, thyroid peroxidase antibody-negative women during each trimester and nonpregnant controls. Thyrotropin, total T4 (TT4), free T4 index (FT4I), and 2 different FT4 immunoassays were(More)
The clinical translation of tissue engineering approaches is limited by the requirement of a cell source. Cell guidance is a new concept that provides an alternative approach, obviating a requirement for an external cell source. This relies on site-specific homing and differentiation of the patient’s own cells to an implanted scaffold through controlled(More)
OBJECTIVE To investigate the mechanism of propranolol on regression of infantile hemangiomas. BACKGROUND Propranolol has been found to be effective in treatment of severe hemangiomas of infancy. However, its mechanism of action is as yet unknown. METHODS Cultured proliferating and involuting hemangioma endothelial cells were treated with varying(More)
BACKGROUND Duplication of the pituitary gland (DPG) is a rare craniofacial developmental anomaly occurring during blastogenesis with postulated etiology such as incomplete twinning, teratogens, median cleft face syndrome or splitting of the notochord. The complex craniocaudal spectrum of blastogenesis defects associated with DPG is examined with an(More)
Complications of the semicircular flap technique of eyelid reconstruction include lateral canthal webbing, ectropion, lid notching, symblepharon, and tissue fullness of the lateral lid. These difficulties occur infrequently and rarely cause significant problems. Attention to surgical details, however, can minimize unfavorable results. It should be(More)
Recent increases in terrorist activity around the world have made analyzing and understanding such activities more critical than ever. With the help of organizations such as the National Center for the Study of Terrorism and Responses to Terrorism (START), we now have detailed historical information on each terrorist event around the world since 1970.(More)
The appearance of bilateral sixth-nerve palsy is usually a harbinger of serious intracranial disease or a nonspecific sign of increased intracranial pressure from any cause. Although unilateral sixth-nerve palsy is a well-recognized complication of lumbar puncture, the appearance of bilateral sixth-nerve palsy following water-soluble myelography is not(More)
BACKGROUND The aim of this study was to compare the incidence of neuroma formation and neuropathic pain following different techniques of nerve ablation in a rat sural nerve model. METHODS Rat sural nerve was subjected to four different techniques of ablation with standardized creation of a 1-cm gap (n = 15 in each group). These included nerve avulsion,(More)
True ossification within benign brain tumors is rare, and the molecular mechanism for this process is poorly understood. The authors report a case of ossified choroid plexus papilloma (CPP) and analyze it to help elucidate the underlying molecular basis of osteogenesis in benign brain tumors. A 21-year-old man presented with headache and depression that(More)
