Calciphylaxis is a rare, life-threatening cause of skin necrosis. The condition is primarily reported in patients with end-stage renal disease, and is associated with significant morbidity and mortality. Treatment has mainly been empirical. We report a case of calciphylaxis in a patient with normal renal function and hypoparathyroidism, who responded to treatment with sodium thiosulfate. To our knowledge, this is the first reported case of the use of sodium thiosulfate to treat calciphylaxis in a patient with normal renal function.

BACKGROUNDPseudomonas aeruginosa is responsible for a wide range of infections. In immunocompromised patients with cancer, the emergence of multidrug resistant P. aeruginosa may have grave consequences.METHODSPatients with cancer who were infected with multidrug‐resistant P. aeruginosa with polyclonal DNA restriction patterns were used as the case group. Two control groups were used: one group of cancer patients who were infected with multidrug‐susceptible P. aeruginosa and another group of cancer patients who had the same underlying disease and the same intensive care unit exposure as patients in the case group but who were not infected or colonized by P. aeruginosa.RESULTSRisk factors that were associated significantly with multidrug‐resistant P. aeruginosa infection were the use of carbapenem for ≥ 7 days, a history of P. aeruginosa infection during the preceding year, and a history of chronic obstructive pulmonary disease (P < 0.01).CONCLUSIONSCarbapenems may need to be used more judiciously as first‐line empirical therapy for cancer patients with prior pseudomonal infection or chronic obstructive pulmonary disease who require hospitalization, and alternative, antipseudomonal antibiotic regimens may need to be considered, especially in this patient population.

Catheters coated with minocycline and rifampin significantly decreased the incidence of central line-associated bloodstream infection in the medical intensive care unit in a manner that was independent and complementary to the infection control precautions. Although this study strongly suggests an association between catheters coated with minocycline and rifampin use and a decrease in central line-associated bloodstream infection, because of multiple other concurrent interventions, the results should be interpreted cautiously until a prospective study is conducted. Furthermore, long-term use of these devices is not associated with increased resistance of staphylococcal isolates to tetracycline and rifampin in the intensive care unit or throughout the hospital.

Despite the steady use of vancomycin, the active surveillance program among high-risk patients with hematologic malignancy and those who were critically ill resulted in the complete control of VRE outbreak bacteremia at our institution.

Concentration of bioaerosol contamination with Aspergillus species was increased in rooms sampled 1 hour after cleaning compared with rooms sampled before cleaning, suggesting a possible correlation between re-entrained bioaerosols (ie, those suspended by activity in the room) after cleaning and the risk of nosocomial invasive aspergillosis.
