Kounis syndrome: two extraordinary cases.

Acute myocardial infarction occurring during the course of an allergic reaction constitutes the Kounis syndrome. This syndrome is caused by inflammatory mediators released mainly from activated mast cells and the interrelated via bidirectional stimuli macrophages and T-lymphocytes. Since activated mast cells abound at the areas of plaque erosion or rupture in patients suffering from acute myocardial infarction a common pathway between allergic and non allergic coronary events seems to exist. Two cases of this syndrome are described, the first following nicorette transdermal application and subsequent finger pricking by fish bone and the second after ciprofloxacin administration.

Large hydatic cyst of the left ventricle associated with syncopal attacks.

An unusual case of giant hydatic cyst of the left ventricle producing cardiac and systemic symptomatology is described. The patient had suffered presyncopal and syncopal attacks and the final diagnosis was made by combination of echocardiography, magnetic resonance imaging and serological tests. Surgical resection of the cyst supplemented by medical therapy yielded favorable results.

Snake venom poisoning in Greece. Experiences with 147 cases.

BACKGROUND: Snake venom poisoning is a medical emergency requiring immediate attention. Bites from poisonous European snakes can lead to local tissue damage and systemic symptoms. Vipera ammodytes accounts for the most envenomation in Greece. METHODS: The demographic and epidemiological characteristics, clinical symptoms and signs, laboratory findings, treatment, and outcome of 147 consecutive victims of V. ammodytes admitted to our hospital from 1988 to 2003 were reviewed and analyzed. RESULTS: The most common symptoms and signs included fang marks (100%), pain (100%), swelling (98.64%), ecchymosis (60.54%), tachycardia (32.65%), fainting or dizziness (29.93%), fever (23.13%), enlargement of regional lymph nodes (17.69%), nausea (16.33%), hypotension (13.61%), and vomiting (12.93%). The main complications were reduced range of motion, thrombophlebitis, local hemorrhagic blister formation, skin bleeding, rhabdomyolysis, reduced sensation, acute renal failure, necrosis with tissue loss, carpal tunnel syndrome, compartment syndrome, Kounis syndrome, and digit amputation. CONCLUSIONS: A V. ammodytes bite is a potentially serious event that requires immediate hospital care. Yet, the majority of victims can be treated successfully with conservative methods. No deaths occurred in our series.
