Thyroglossal duct cysts: a consideration in adults.

Thyroglossal duct cysts (TDC) are one of the most common pediatric midline neck lesions. Although they are present from birth, they usually become symptomatic in early childhood as a mass or draining sinus. Infection and abscess formation are frequent complications due to a communication between the cyst and the mouth with subsequent contamination by oral flora.

A retroperitoneal bleed induced by enoxaparin therapy.

Retroperitoneal bleeding is one of the most serious, potentially lethal complications of anticoagulation therapy. Although well documented in fully heparinized and coumadinized patients, there are only few reports of life-threatening hemorrhages in low-molecular-weight heparin (LMWH)-treated patients. We present a case of almost fatal spontaneous retroperitoneal bleeding in a 71-year-old woman with pneumonia and acute coronary syndrome.

Ruptured umbilical hernia in a case of alcoholic cirrhosis with massive ascites.

Umbilical hernias are common in patients with cirrhosis of the liver and ascites. However, spontaneous rupture of the hernia is not frequently seen. This is a serious complication and carries a high mortality.
