Introduction: resent studies have been shown that normobaric hyperoxia (HO) can induce excitotoxicity and stress oxidative tolerance (ETT) in variety of organs such as brain. In this study, we examined the intermittent dose of normobaric hyperoxia (HO) on neurologic deficit, and superoxide dismutase activity in brain tissue of Huntington animal model. Method: The rats were divided to three...

Shoulder pain is a common musculoskeletal ailment. The process of determining the etiology of shoulder pain can be difficult. The differential diagnoses include: both intracapsular and extracapsular lesions; and neurologic, vascular, postural, and visceral causes. We present an unusual case of shoulder pain accompanied by loss of shoulder range of motion (ROM), initially thought to be caused by...

Triple A Syndrome is an autosomal recessive neurodegenerative disorder characterised by central and peripheral nervous system disturbances, autonomic dysfunction, alacrima, achalasia, and ACTH-resistant adrenal insufficiency (1). It results from mutations in the AAAS gene located on 12q13 which encodes the WD-repeat protein ALADIN (2) (ALacrima Achalasia aDrenal Insufficiency Neurologic disorde...

OBJECTIVE Griscelli syndrome (GS) is a rare autosomal recessive immune deficiency disorder that presents with pigmentary dilution of the skin and hair, recurrent skin and pulmonary infections, neurologic problems, hypogammaglobulinemia, and variable cellular immunodeficiency. Three mutations have been described in different phenotypes of the disease. In most of cases, GS leads to death in the f...

objective: hashimoto encephalopathy (he) is known as a steroid-responsive encephalopathy associated with autoimmune thyroiditis or nonvascular inflammation-related autoimmune meningoencephalitis. the average age of onset of he is approximately 50 years; and it is more common in women. the onset of he may be acute or subacute. the course of most he cases is relapsing and remitting, which is simi...

Irritable Bowel Syndrome (IBS), which is classified as a functional gastrointestinal disorder, is a chronic condition of the lower gastrointestinal tract (Figure 1) that affects as many as 15% of adults in the United States. Not easily characterized by structural abnormalities, infection, or metabolic disturbances, the underlying mechanisms of IBS have for many years remained unclear. Recent re...

The enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT) catalyzes the reutilization of hypoxanthine and guanine to the purine nucleotides IMP and GMP, respectively. HPRT deficiency is an X-linked disorder characterized by uric acid overproduction and variable neurologic impairment. The complete deficiency of HPRT is diagnostic of Lesch-Nyhan syndrome manifested by choreoathetosis, spas...

Langerhans cell histiocytosis (LCH) is a rare myeloid neoplastic disorder typically seen in children and characterized by infiltrative bone lesions. The skin, the lungs, liver, central nervous system may also be involved. even more unusual adults presents diagnostic challenge, given that its imaging characteristics are similar to those of other, prevalent processes. We report case LCH 28-year-o...

CD is an autoimmune-mediated disorder of the gastrointestinal tract. Initial symptom presentation is variable and can include neurologic manifestations that may comprise ataxia, neuropathy, dizziness, epilepsy, and cortical calcifications rather than gastrointestinal-hindering diagnosis and management. We present a case of a young man with progressive neurologic symptoms and brain MR imaging fi...
