leiomyoma of nasal cavity is a rare and benign tumor of smooth muscle origin that uncommonly arises from the nasal septum. we present an unusual case of histopathologically diagnosed locally extensive leiomyoma of the nasal septum which was clinically and radiologically misdiagnosed as malignancy of the nasal cavity. this case report emphasizes the rare occurrence of this entity at this site an...

Henri Roger, in 1879, was the first to accurately describe the clinical manifestations of ventricular septal defect, and the term “maladie de Roger” is often used in connection with these malformations. The lesion and the problems associated with it have attracted a great deal of attention in recent years, particularly with the advent of open heart surgery and a means for affecting a cure. Embr...

Twenty-one patients with partial anomalous pulmonary venous drainage with intact atrial septum have been studied. These include 13 patients not previously reported from our laboratories and eight patients with complete hemodynamics reported by others. Methods for identification of this abnormality and for identification of an intact atrial septum are described, including differential indicator ...

Bacillus subtilis penicillin-binding protein PBP1 has been implicated in cell division. We show here that a PBP1 knockout strain is affected in the formation of the asymmetric sporulation septum and that green fluorescent protein-PBP1 localizes to the sporulation septum. Localization of PBP1 to the vegetative septum is dependent on various cell division proteins. This study proves that PBP1 for...

Transverse vaginal septum is a rare occurrence. When it co-exists with cervical dysgenesis, it is even rarer. Primary amenorrhea with cyclic pain is one manifestation in post-pubertal women. A case of transverse vaginal septum with vaginal atresia and cervical dysgenesis is presented. Presentation as a huge abdominal mass and severe anaemia posed diagnostic challenges. A two-staged management i...

BACKGROUND Several authors have reported cases in which 201Tl scintigraphy demonstrated perfusion abnormality in the septum of patients with left bundle branch block (LBBB) and normal coronary arteriogram. The mechanism of this abnormality, however, remains to be clarified. METHODS AND RESULTS To determine whether LBBB itself induces abnormal myocardial perfusion and ischemia and to elucidate...

During pulmonary artery constriction (PAC), an experimental model of acute right ventricular (RV) pressure overload, the interventricular septum flattens and inverts. Finite element (FE) analysis has shown that the septum is subject to axial compression and bending when so deformed. This study examines the effects of acute PAC on the left ventricular (LV) free wall and the role the pericardium ...

Aneurysm of the sinus of Valsalva that causes dissection of the interventricular septum is an extremely rare entity. In this report we describe a case of aneurysm of the sinus of Valsalva dissecting into the interventricular septum, from the base to mid septum, after aortic valve replacement. After the diagnosis was made by transthoracic echocardiography and magnetic resonance imaging, the pati...

Stretcher operation of the electron storage ring, KSR has been tested with 80 MeV electron beam. Beam injection with closed orbit control and beam extraction channel consisting of the electrostatic septum with 70 kV/cm and septum magnet of 5kG with septum thickness of 14 mm have been completed. Beam spill can be enlarged to ~1 s by the slow extraction with combined use of the third order resona...

Hypoplasia of the right ventricle is uncommon as an isolated entity. It may result from tricuspid atresia, but is most commonly secondary to pulmonary atresia with intact ventricular septum. Pulmonary atresia with intact ventricular septum is rare, accounting for 1-3% of cases of congenital heart disease. It occurs in 0.1 to 0.4 in 10,000 live births. Pulmonary atresia with intact ventricular s...
