Obstructive sleep apnea and electrocardiographic P-wave morphology.

Introduction: Obstructive sleep apnea (OSA) is a highly prevalent sleep disorder with important cardiovascular implications. Left atrial abnormality can be identified by electrocardiographic P-wave morphology and is considered an important risk for atrial fibrillation (AF) and stroke, both of which have been associated with OSA. We hypothesized that severity of OSA would be associated with more abnormal electrocardiographic P-wave morphology as indicated by P-wave terminal force in V (PTFV ) and P-wave area in V (PWAV ).

Emerging Aspects of the Body Composition, Bone Marrow Adipose Tissue and Skeletal Phenotypes in Type 1 Diabetes Mellitus.

Anthropomorphic measures among type 1 diabetic patients are changing as the obesity epidemic continues. Excess fat mass may impact bone density and ultimately fracture risk. We studied the interaction between bone and adipose tissue in type 1 diabetes subjects submitted to two different clinical managements: (I) conventional insulin therapy or (II) autologous nonmyeloablative hematopoietic stem-cell transplantation (AHST).

Congenital and acquired blepharoptosis.

Blepharoptosis is a relatively common condition that is frequently encountered by the ophthalmic surgeon. Treatment remains somewhat unpredictable, and the choice of one of the various surgical options depends on the cause of the ptosis and the amount of levator function. Recent contributions to the literature on the classification and management of ptosis are reviewed here.

Course of proptosis in patients with Graves' disease after endoscopic orbital decompression.

Aim: To evaluate the results of follow-up and postoperative course of proptosis in patients with Graves' disease who underwent combined transconjunctival and transnasal endoscopic orbital decompression.

Methods: Charts of patients with Graves' disease who underwent orbital decompression using combined transconjunctival and transnasal endoscopic technique were reviewed. The surgical technique involved preservation of the strut of bone between the lamina papyracea of the ethmoid and floor of the orbit of the maxilla.

Orbital complications of sinusitis in the aspirin triad syndrome.

Orbital complications are uncommon in adult sinusitis. In contrast, the sinusitis of the aspirin triad syndrome is often fulminate, expansive, and recurrent, and complications may be more frequent. Of 81 patients with aspirin triad who were treated surgically, 7 patients (8.
