BACKGROUND C225 is an antibody to the epidermal growth factor receptor (EGFR), and inhibits growth of various tumour cells. The antibody is currently being used as a therapeutic agent in several clinical trials of patients with carcinomas. Objectives To determine and investigate the cutaneous side-effects in cancer patients treated with C225. Methods We(More)
Disseminated infection with Mycobacterium avium complex developed in 67 patients with the acquired immunodeficiency syndrome (AIDS) who were followed at Memorial Sloan-Kettering Cancer Center. Twenty-nine patients were treated with two or more antimycobacterial drugs for a mean of 6 weeks, and 7 patients received therapy for less than 1 month. Most patients(More)
Reports of the association of Mycobacterium haemophilum with disease in humans have greatly increased. At least 64 cases have now been reported, with symptoms ranging from focal lesions to widespread, systemic disease. The organism is now known to cause primarily cutaneous and subcutaneous infection, septic arthritis, osteomyelitis, and pneumonitis in(More)
D-Arabinitol is a five-carbon polyol that is produced by many fungi. Detection of the metabolite has been reported in serum from patients with invasive candidiasis. We studied the production and assimilation of arabinitol by 46 clinical isolates of yeast species. Cultures of isolates of Candida albicans (9 strains), Candida tropicalis (12 strains), Candida(More)
Bloodstream infection caused by vancomycin-resistant enterococcus (VRE) is associated with very high mortality among allogeneic hematopoietic stem cell transplant (alloHSCT) recipients. However, it remains unclear whether VRE bloodstream infection directly causes mortality in the early posttransplant period or is simply a marker of poor outcome. To(More)
The Mycobacterium avium complex, only rarely described as an invasive pathogen in humans, has recently been reported to frequently cause disseminated disease in patients with the acquired immune deficiency syndrome. Between February 1981 and February 1984 at Memorial Sloan-Kettering Cancer Center, 30 patients with acquired immune deficiency syndrome, 3(More)
Fungemias were reviewed in 110 immunocompromised patients hospitalized between November 1, 1974, and December 31, 1977, a Memorial Sloan-Kettering Cancer Center (MSKCC). The incidence of Candida tropicalis fungemia increased each year. Seventy-six percent of the patients with C. tropicalis fungemia and 32.5 percent of those with C. albicans fungemia had(More)
PURPOSE Surgically implanted central venous catheters are widely used in cancer patients in whom there is a need for prolonged venous access for chemotherapy, parenteral nutrition, antibiotics, and blood sampling. This study evaluated catheter infectious complications, including catheter-related sepsis, exit site infection, and tunnel infection.(More)
BACKGROUND Viridans streptococcal bacteremia (VSB) after allogeneic hematopoietic stem cell transplantation (HSCT) is associated with substantial mortality. Prevention of this serious complication is therefore a high priority. The objective of this study was to evaluate the effect of early vancomycin administration on rates and outcomes of VSB. METHODS We(More)
Mycobacterium genavense, a recently reported cause of a wasting illness in patients with AIDS, was isolated from a cervical lymph mode from a dog with severe hind limb weakness and from trachael tissue from a parrot with acute onset respiratory distress. Physicians caring for immunocompromised patients should consider birds and dogs potential sources of M.(More)
