Spontaneous clostridial myonecrosis (gas gangrene) is an uncommonly encountered presentation of skin and soft-tissue infections with high morbidity and mortality. The diagnosis has been associated with colorectal carcinoma, hematologic malignancies, and diabetes. We report the case of an 81-year-old man who experienced a sudden onset of left ankle and foot pain in association with nonpalpable purpura and hemorrhagic bulla. ⋯ Cultures grew Clostridium septicum, and a large cecum mass was found by computed tomography of the abdomen. A subsequent right hemicolectomy confirmed a well to moderately differentiated mucinous adenocarcinoma. We emphasized that the early recognition of necrotizing skin and soft-tissue infections warrants further evaluation and appropriate management.

Inhalant abuse is the intentional inhalation of chemical vapors or volatile substance to achieve a euphoric effect. Although no statistical data are reported yet, inhalant abuse is potentially life-threatening and has resulted in a wide range of toxic effects such as central nervous system depression, seizures, aspiration, cardiac arrhythmia, asphyxiation, hypoxia, metabolic acidosis, and sudden death among others. ⋯ The patient also had a prolonged QT interval, mild inspiratory stridor, but no urticaria. In this case, we believe the difluoroethane-related angioedema represents either idiopathic or bradykinin-induced angioedema.

Necrotizing fasciitis is an uncommon but life-threatening condition with a high associated mortality and morbidity. Most infections are polymicrobial, another distinct form of necrotizing fasciitis that occurred by penetrating freshwater trauma, such as fishing or wading in wet fields. Aeromonas species are responsible. ⋯ An apparent superficial cellulitis that fails to respond to standard therapy must raise suspicion of a more extensive underlying subcutaneous infection. Aggressive surgical debridement and antibiotic coverage for gram-negative rods are the essential features of treatment. Delay caused by a mistaken diagnosis of cellulitis and subsequent inadequate debridement would likely prove fatal.

The prognostic role (if any) of lactate for early mortality in patients with ST-elevation myocardial infarction (STEMI) submitted to primary percutaneous coronary intervention (PCI) is so far not elucidated. We therefore assessed whether lactic acid (LA) was a prognostic predictor for early mortality in 807 patients with STEMI submitted to primary PCI consecutively admitted to our intensive cardiac care unit (ICCU) from January 1, 2006, to December 31, 2009. ⋯ In patients with STEMI submitted to primary PCI, blood lactate is a prognostic marker for early mortality only in the subgroup with advanced Killip class. The degree of hemodynamic impairment (as indicated by Killip class), of myocardial ischemia (as inferred by troponin I), and glucose values are the main factors influencing lactate concentrations in the early phase of STEMI.

A 65-year-old man with recently diagnosed urinary tract infection treated with ciprofloxacin (Cipro) presented to our institution with recurrent seizure-like activity. His rhythm revealed torsade de pointes, which required defibrillation. ⋯ This case highlights a rare but potentially fatal side effect of quinolone antibiotics, especially in combination with other QT-prolonging medications. Review of the literature with regard to prevalence, mechanism, and assessment and treatment of this potentially fatal incidence is provided.
