The genetic epidemiology of late-onset idiopathic Parkinson's disease (PD) and 'parkin-proven' parkinsonism (AR-JP) are limited. The clinical phenotype, prognosis and treatments are similar although PD is prevalent while AR-JP is rare. Molecular genetic and functional analysis suggests the E3 ubiquitin protein ligase activity of parkin, and the ubiquitin-proteosomal pathway, is central to disea...

In a 62-year-old man with permanent atrial fibrillation and recurrent stroke, a large right atrial thrombus attached to a permanent pacemaker lead was incidentally identified by transesophageal echocardiography. Surgical treatment, recommended because of the large dimensions of the mass, was refused by the patient, and thrombus was successfully dissolved by anticoagulant treatment. Pathogenesis...

Mucormycosis is a clinical entity attributed to opportunistic fungal infection of order Mucorales. This includes several pathogenic subtypes. It commonly affects the rhinocerebral sites and the immunocompromized patients with devastating results. Visceral mucormycosis is a relatively rare complication. We report the first free sigmoid colon perforation secondary to invasive mucormycosis and dis...

There have been remarkable recent advances in oncogenomics of cancer, which have allowed enhanced understanding of disease pathogenesis. Each issue of Clinical Cancer Research reflects this progress, with original reports describing novel insights into human cancer biology and pathophysiology, usually in the context of a particular disease setting. The goal of our newest feature, The Clinical C...

background: little in known regarding the clinical relevance of sirt1 in multiple sclerosis (ms).   here, we aimed to evaluate mrna expression, protein level and enzyme activity of sirt1 in peripheral blood mononuclear cells (pbmcs) isolated from relapsing –remitting ms patients (rrms) and healthy controls. materials and methods: twenty patients with rr-ms and twenty two age- and sex-matched he...

Infective endocarditis is a rare but life-threatening microbial infection of the heart valves or endocardium, most often related to congenital or acquired cardiac defects. The American Heart Association (AHA) recently updated its recommendations on prophylaxis during dental procedures. The revisions will have a profound impact on both the patient and the dental practitioner. The purpose of this...
