Aneurysm of the interventricular membranous septum is a very rare cardiac anomaly in the absence of ventricular septal defect. We report the case of a 22-year-old man with aneurysm of the interventricular membranous septum incidentally determined during aortic valve surgery. The patient underwent successful aortic valve replacement and aneurysm repair. Patients with the aneurysm of the interven...

Membranous lipodystrophy is characterized by the presence of microcysts lined by amorphous, eosinophilic material with an arabesque appearance. We experienced a case of a 72-year-old man who had dark brownish, pruritic papules on the arms, legs, and back. Histopathologic examination of a biopsied lesion showed homogeneous, eosinophilic material in the papillary dermis, as well as membranous lip...

BACKGROUND Hepatitis C virus (HCV), like other positive-sense RNA viruses, replicates on an altered host membrane compartment that has been called the "membranous web." The mechanisms by which the membranous web are formed from cellular membranes are poorly understood. Several recent RNA interference screens have demonstrated a critical role for the host phosphatidylinositol 4-kinase PI4KA in H...

Objective In a group case series, the clinical characteristics of congenital membranous cataract in children were studied to establish a system of classification and determine the surgical method suited for each type. Methods Children (18 eyes) with congenital membranous cataract were examined by slit lamp, ultrasound biomicroscopy, and operating microscopy to classify cataracts. The clinical...

Stable posture and body movement in humans is dictated by the precise functioning of the ampulla organs in the semi-circular canals. Statistical analysis of the interrelationship between bony and membranous compartments within the semi-circular canals is dependent on the visualization of soft tissue structures. Thirty-one human inner ears were prepared, post-fixed with osmium tetroxide and deca...

PURPOSE To predict lymph node metastasis and prognosis in head and neck squamous cell carcinoma (HNSCC). RESULTS The combination of membranous E-cadherin and membranous epidermal growth factor receptor (EGFR) quantified by QD technology with age, gender, and grade had greater predictive power than any of the single biomarkers or the two combined biomarkers quantified by conventional immunohis...

The left ventricular outflow tract is here considered to be that region of the left ventricle that lies between the anterior cusp ofthe mitral valve and the ventricular septum. The ventricular septum lies at an angle of45 degrees to the median plane. The 'anterior' wall of the outflow tract is therefore anteromedial and the 'posterior' wall is posterolateral. In the anterior wall are both the m...

PATIENT Male, 83 FINAL DIAGNOSIS: Membranous glomerulonephritis Symptoms: Producting cough Medication: - Clinical Procedure: - Specialty: Nephrology. OBJECTIVE Rare disease. BACKGROUND Membranous glomerulonephritis can occur secondarily from infectious diseases. There are no reports describing membranous glomerulonephritis caused by non-tuberculous mycobacterium infection. However, several ...

PURPOSE OF REVIEW The morphological features of membranous nephropathy have been recognized for over five decades, but the pathogenetic mechanisms underlying this lesion in humans have only recently been elucidated. This review analyzes the recent developments in understanding the pathogenesis of the primary and secondary forms of membranous nephropathy. RECENT FINDINGS Seminal studies have i...

Idiopathic membranous glomerulonephritis (IMGN) is one of the most common causes of nephrotic syndrome in adults. Disease progression is associated with the magnitude and duration of proteinuria [Reichert LJ, Koene RA, Wetzels JF. Prognostic factors in idiopathic membranous nephropathy. Am J Kidney Dis 1998; 31: 1-11]. Membranous nephropathy is also one of the glomerular diseases that is well d...
