Emergency surgical treatment of cervico-mediastinal lymph-haemangioma in a 2-month-old infant, indicated by acute inner tumour haemorrhage.

Unlabelled: Cervico-Mediastinal Lymphangiomas (CML) are caused by atresia of the efferent lymphatics or lack of communication between lymphatics and venous channels. Cervico-Mediastinal Lymphangiomas in certain cases require emergency surgery to secure decompression of the airways. The purpose of this study is to present a multidisciplinary surgical approach in the treatment of urgently complicated Cervico-Mediastinal Lymphangiomas, and to asses the surgical tactics and satisfactory outcome after a two-stage operation.

Severe Hypokalemia Masquerading Myocardial Ischemia.

An advanced degree of body potassium deficit may produce striking changes in the electrocardiogram (ECG). These changes can result in incidental findings on the 12-lead ECG or precipitate potentially life-threatening dysrhythmias. Although usually readily recognized, at times these abnormalities may be confused with myocardial ischemia.

'Silent' Prinzmetal's ST elevation related to atenolol overdose.

Prinzmetal's angina is a condition characterized by chest pain, transient ST elevation, and negative biochemical markers of myocardial cell necrosis. We describe a case of chemically-induced "silent" ST segment elevation related to Atenolol overdose in a patient without coronary artery stenosis. We conclude that the cause for the transient myocardial ischemia is coronary vasospasm, precipitated by beta-blocker overdose.
