A total of 30 patients with suspected urethral strictures underwent sonographic and roentgenographic urethrograms. Two showed a normal anterior urethra in the sonourethrogram; 29 were diagnosed remaining 28 patients, 1 patient showing at two different sites. Sonourethrography was an accurate predictor stricture length, retrograde urethrography underestimating length most cases. Periurethral structures, including wall, corpus spongiosum, corpora cavernosa, bulb, external urinary sphincter,...

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare but well-reported clinical entity. It classically described as involvement of both upper extremities. Asymmetrical had also been reported, unilateral presentation very rare. We hereby report case RS3PE in patient rheumatoid arthritis which was initially misdiagnosed cellulitis and given high dose antibiotics without any significant improvement. Later rheumatologic consultation leads to prompt diagnosis,...

Abstract Takotsubo's cardiomyopathy (TC) typically presents with acute cardiac dysfunction due to regional wall motion abnormality, but unlike other pathologies, it recovers within a short period. Here, we report the case of 23-year-old woman who presented us following severe traumatic brain injury (TBI). Her Glasgow coma scale (GCS) deteriorated rapidly in preoperative period and she developed TC surgery. Despite an uneventful surgery, needed cardiovascular support by vasopressors inotropes...

We report a case of 22-year-old woman who presented with recurrent episodes quadriparesis, often accompanied by jaundice. Neurologic examination showed symmetrical proximal predominant quadriparesis generalized hyporeflexia. The differential diagnoses included were metabolic, inflammatory, genetic (including channelopathies), and autoimmune causes. Serum creatine phosphokinase levels electrophysiologic studies helped narrow the differential. final diagnosis was one that responsive to vitamin...

Varicella zoster virus (VZV) is well known for its neurotropism, primary infection and reactivation after variable latency periods. After from spinal or cranial nerve ganglia, viruses can affect the central nervous system vasculature via transaxonal migration followed by transmural spread adventitial layer to intima. Stroke occur following VZV (varicella) (zoster). These infectious vasculitides lead unifocal multifocal ischemic hemorrhagic stroke either dermatomal zoster. Usual difference...
