Case report of a posterior pharyngeal wall schwannoma in a 23-year-old female. Hypopharyngeal schwannoma is rare entities and at the time of writing we could find only 10 other cases reported worldwide and this is the eleventh. Complete excision was done intraorally and there is no recurrence after 1 year.

We analyzed hemodynamic variables in patients with transposition of the great arteries with intact ventricular septum (simple transposition) after pulmonary artery banding and Blalock-Taussig anastomosis to establish the criteria for two-staged arterial switch operation. The study included 35 patients who underwent the switch operation after banding and anastomosis; two died shortly after surge...

Abstract Background Thalassemia intermedia is a variety of beta thalassemia which shows clinical symptoms somewhere between asymptomatic carriers and thalassemia major. Cardiac dysfunctions due to chronic anemia and hemosiderosis are the major causes of death in these patients. The purpose of this study is to evaluate cardiac function in these patients by echocardiography. Materials and Met...

Dear Editor, would suggest recalculating the data with respect to Recently, Lodi et al. described a deficiency of cardiac accepted definitions of myocardial hypertrophy. energetics in Friedreich’s ataxia (FRDA) patients in the absence of cardiac dysfunction and hypertrophy [1]. The authors concluded that cardiac metabolic dysfunction proceeds the development of myocardial hypertrophy. R eferenc...

longitudinal heat conduction is an important parameter in the cryogenic field, especially in cryogenic heat exchangers. in the present work, the parasitic effect of tube wall longitudinal heat conduction on temperature measurement has been studied in cryogenic laminar hydrogen flow. the effects of various parameters such as wall cold end temperature, wall thermal conductivity, gas volumetric fl...

Objective- To find normal value of thickness of the lens capsules in domesticated rabbits by ultrasonography. Design- experimental in vivo study and clinical trial. Animals- Twelve matured and immature domesticated rabbit. Procedures- The eyes of 12 non anaesthetized domesticated rabbits were sonograophed using a linear 6-12 MHz high frequency transducer. The thickness of anterior and posterior...

Frontal sinus fractures are of surgical importance because of the microbial flora covering the frontal air sinus and it's proximity with the duramater and brain. There is an increased risk of meningitis when fracture of the posterior wall of the frontal sinus is associated with a dural tear. In this condition, communication occurs between the contaminated space of the air sinus and the intr...

Acute myocarditis is a rare disease with a very diverse etiology. It produces a wide spectrum of clinical manifestations and in some cases has a fulminant course. The degree of echocardiographic impairment of myocardial contractility is also highly variable, ranging from no abnormalities to a severe deterioration in systolic function. The pattern of the condition may be diffuse or focal, and it...

PURPOSE To study the relationship between intraocular pressure (IOP) and the IOP-related stress (force/cross-sectional area) it generates within the load-bearing connective tissues of the optic nerve head. METHODS Thirteen digital, three-dimensional geometries were created representing the posterior scleral shell of 13 idealized human eyes. Each three-dimensional geometry was then discretized...
