Calciphylaxis is a condition of induced hypersensitivity in which tissues respond to challenge agents with local calcification. This article reports the first known case of diffuse calciphylaxis associated with acute myeloid leukemia resulting in death from hypoxic respiratory failure and refractory hypotension.

We present a case of significant, persistent, and relatively refractory hypotension during general anesthesia in a reasonably healthy 50-year-old man thought to be caused by a direct rennin inhibitor. This case is of particular significance because the medication thought responsible for the hemodynamic abnormalities is a relatively novel antihypertensive agent and remains largely unknown to cli...

Accidental/suicidal ingestion of metal phosphides (e.g., zinc phosphide found in rodenticides) should be suspected in patients with sudden-onset abdominal pain, refractory hypotension, and metabolic acidosis. CT angiography may show radiopaque substance in the stomach and early enhancement of the inferior vena cava and contrast in right side of the heart.

Hypotension after reperfusion is a common occurrence during liver transplantation following the systemic release of cold, hyperkalemic, and acidic contents of the liver allograft. Moreover, the release of vasoactive metabolites such as inflammatory cytokines and free radicals from the liver and mesentery, compounded by the hepatic uptake of blood, may also cause a decrement in systemic perfusio...

BACKGROUND Management of refractory status epilepticus (SE) involves administration of intravenous γ-aminobutyric acid (GABA(A)) receptor agonists, such as benzodiazepines, barbiturates, or propofol. Animal models suggest that reductions in synaptic GABA(A) receptors may cause these drugs to become less effective as the duration of SE increases. This may explain the large doses that are commonl...

Due to their beneficial reduction in morbidity and mortality angiotensin receptor blockers (ARBs) have become increasingly popular to treat hypertension. However, similar to angiotensin converting enzyme inhibitors, they can lead to severe hypotension in conjunction with general anesthesia and thus have been recommended to be withheld in the morning of surgery. Here, we present a 51 year old fe...

background: in this study, we compared the efficacy and safety of propofol and midazolam in treatment of children’s refractory status epilepticus.   methods: we recruited 32 patients with refractory status epilepticus. of those, 16 were treated primarily with midazolam and 16 received propofol.   results: we achieved complete seizure control in 6 (38%) patients treated by midazolam, and in 10 (...

Five preterm, very low birthweight infants with severe hypotension and adrenocortical insufficiency are described. The profound hypotension was resistant to volume expansion and inotrope treatment, but responded promptly to corticosteroid treatment. A human corticotrophin releasing hormone (hCRH) test performed before corticosteroid treatment showed adequate pituitary response, and the endocrin...
