This presentation reflects an atypical manifestation of sinoatrial block in a patient with chronic renal failure and hyperkalemia (7.8 mEq/L). An allorhythmic distribution of P-P intervals permits the interpretation of sinoatrial block complicated by sinoatrial reciprocation.

Creutzfeldt-Jakob disease may have many atypical presentations before the development of classic progressive dementia and startle myoclonus. In two patients with pathologically established disease association with a progressive alien hand syndrome was the sole initial manifestation of the disease.

The emerging of new H7N9 influenza virus infection in February 2013 brings attention of world health scientists on its possibility to cause worldwide pandemic. The new H7N9 bird flu is a new disease manifesting with acute respiratory features plus additional atypical clinical manifestations. Of those atypical clinical features, neurological presentation is an interesting issue. This work presen...

Respiratory distress by laryngospasm as an isolated manifestation of epileptic seizure is rare phenomenon. We report on a 1-month-old infant with recurrent respiratory distresses by laryngospasm as an isolated manifestation of status epilepticus and resultant periarrests, while being monitored in our intensive care unit. This case of an atypical manifestation of status epilepticus highlights th...

Introduction: Dentin dysplasia is a rare autosomal dominant inheriting disturbance of dentin formation characterized by normal enamel formation, but atypical dentin with abnormal pulpal morphology. There are two major patterns: type I and type II. Amelogenesis imperfecta is an autosomal dominant. X-link inherent disease that is classified by clinical manifestation into hypoplastic, hyp...

Severe Combined Immunodeficiency (SCID), characterized by a profound decrease in both the number and function of T cells, is related to more than 20 different mutations. Recombination-activating gene (RAG) 1 and 2 seem to be two of the most common forms presenting with various manifestations, including typical SCID, Omenn syndrome (OS), atypical SCID (AS), or delayed onset combined immunodefici...

For many years, to reduce the crash frequency and severity at high-speed signalized intersections, warning flashers have been used to alert drivers of potential traffic-signal changes. Recently, more aggressive countermeasures at such intersections include a speed-limit reduction in addition to warning flashers. While such speed-control strategies have the potential to further improve the crash...
