Rhabdomyolysis and Acute Kidney Injury due to Severe Heat Stroke.

We present a case of heat stroke (HS) and acute kidney injury (AKI) due to severe rhabdomyolysis in a 14-year-old previously healthy female patient. When she was practicing strenuous exercise she suffered acute seizures and high fever. These symptoms were followed by coma and multiple organ failure (MOF), which included AKI, encephalopathy, fulminant hepatic failure (FHF), and disseminated intravascular coagulation (DIC).

Spontaneous pneumomediastinum and subcutaneous emphysema in asthma exacerbation: The Macklin effect.

Objective: We describe the clinical features of a 17-year-old girl with severe asthma exacerbations. On admission to the intensive care unit, she manifested expiratory dyspnea, cyanosis, and an unproductive cough. Her chest x-rays showed extensive pneumomediastinum (PM), mild subcutaneous emphysema at the right anterior triangle of the neck, and right upper-lobe atelectasis.

Multiple Organ Failure Following Near Fatal Exertional Heat Stroke.

We describe the clinical features of a patient with near-fatal heat stroke who was admitted to our intensive care unit. A 14-year-old girl became convulsive and hyperthermic when participating in a strenuous hike under direct sunlight in a hilly area in Venezuela on a very hot and humid day. During the following days, she developed multiple organ failure, including neurological impairment, acute renal failure, disseminated intravascular coagulation, and extensive hepatic and muscle damage.

Noncardiogenic pulmonary edema following accidental near-hanging.

A 79 year-old woman was admitted to our institution unconscious with pulmonary edema. She had been trapped by the neck in the electric sliding gate of her own home garage. A pulmonary artery catheter was inserted through the right internal jugular vein and her hemodynamic profile and chest x ray revealed a non cardiogenic pulmonary edema.

Cardiac tamponade due to pneumopericardium.

We describe a newborn with acute respiratory distress syndrome, subjected to mechanical ventilatory assistance with high level of peak inspiratory pressure (PIP) and positive end expiratory pressure (PEEP), who developed cardiac tamponade due to pneumopericardium. Tension pneumopericardium produces the same physiological derangement as cardiac tamponade secondary to accumulated blood or other fluids. This life-threatening complication demands immediate diagnosis and treatment.

Endovascular repair of symptomatic coronary-subclavian steal syndrome due to stenosis of the proximal left subclavian artery.

We report a patient with left subclavian artery stenosis in whom the internal thoracic artery (ITA) had been used as a coronary bypass. She presented with symptomatic myocardial and brain ischemia resulting from coronary-subclavian steal syndrome and was successfully treated with angioplasty and stenting.

Endovascular repair of accidental ligation of the right coronary artery during cardiorrhaphy for penetrating heart wound.

We report a patient with a cardiac penetrating wound who underwent cardiorrhaphy which resulted in accidental ligation of the proximal right coronary artery (RCA), producing a postoperative acute inferior wall myocardial infarction. Although the option of surgical relief of the suture over the RCA was discussed, a repeat operation was considered to be of very high risk. Therefore, an endovascular attempt to recanalize the vessel was chosen.
