Intravenous cefazolin and cefoxitin were compared in a prospective randomized trial in infections where the suspected pathogen was expected to be susceptible to both antibiotics. In the cefazolin group (12 patients) the diagnosis was pneumonia in 4, including 2 with pneumococcal bacteremia, soft tissue infection in 5, Staphylococcus aureus bacteremia in 1, acute pyelonephritis in 1, and disseminated gonococcal infection in 1. In the cefoxitin group (10 patients) the diagnosis was pneumonia in 4, including 2 with pneumococcal bacteremia, soft tissue infection in 4, acute pyelonephritis in 1, and disseminated gonococcal infection in 1. In the cefazolin group receiving an evaluable course of therapy, a good clinical response was seen in 10 of 11 patients, and a bacteriological response was seen in 5 of 7. Cefazolin failed to eradicate S. aureus bacteremia in 1 patient and S. aureus in a skin ulcer of another patient. All 10 cefoxitin patients had good clinical and bacteriological responses, but in 1 patient S. aureus colonization of a postoperative wound recurred after discontinuation of the drug. Side effects in both groups included skin rash, phlebitis, and elevation of the serum alkaline phosphatase. Both cefoxitin and cefazolin appeared effective in infections caused by susceptible aerobic pathogens with the possible exception of S. aureus, although all 11 strains of S. aureus isolated in this study were susceptible in vitro to both antibiotics. Cefoxitin appeared to be equivalent to cefazolin in efficacy and occurrence of side effects.

Calciphylaxis (calcific uremic arteriolopathy) is a poorly understood and highly morbid syndrome of both vascular calcification and skin necrosis. The main histopathological finding is calcium deposits within arteriolar and small vessel walls, showing endovascular fibrosis associated with fat necrosis. The therapeutic strategy is to normalize the high calcium-phosphate products (Ca x P). When calciphylaxis is complicated with advanced renal hyperparathyroidism (HPT), parathyroidectomy (PTX) should be performed promptly. However, for patients with low PTH level, calciphylaxis is unresponsive to PTX, and such an approach may worsen hyperphosphatemia and hypercalcemia. We report two patients with calciphylaxis confirmed by skin biopsy. PTX was performed in both patients based on high PTH levels. PTH and Ca x P level decreased in both patients post PTX. In Case 1, the skin ulcers gradually improved and almost disappeared after PTX. However, in Case 2, new ulcers appeared after PTX. In Case 1, alkaline phosphatase (ALP) after PTX was approximately twice its level before surgery and PTX resulted in normalization of uptake on bone scintigraphy. However, no rise in ALP was noted in Case 2, probably due to long-term use of aluminum, which prevented bone formation. These findings suggest that differences in the extent of bone formation explain the different response in post-PTX ulcer healing.

Critical limb ischemia (CLI) is a severe obstruction of the arteries resulting from seriously decreased blood flow to the extremities, progressing to the point of pain and even skin ulcers or sores. CLI is associated with a high percentage of limb loss and mortality; however, no reliable biochemical indices are available to monitor the stages of CLI. We developed a strategy involving comparative proteomic analysis to detect CLI associated plasma biomarkers. 2D-DIGE and subsequent MALDI-TOF MS analyses provided 50 differentially expressed plasma proteins (including alkaline phosphatase and haptoglobin), between hemodialytic diabetic patients with and without CLI. Interestingly, more than half of the differentially expressed plasma proteins are associated with inflammatory responses. Our results show that CLI is strongly correlated to inflammation, indicating a strong potential for proteomics analysis in the diagnosis of CLI. To the best of our knowledge, this is the first report presenting a proteomics approach to monitor differentially expressed plasma proteins associated with CLI.

A 74-year-old woman had carcinoma of her right breast for which surgery was performed. Four weeks following the start of tamoxifen therapy, she developed papules and plaques over her face, trunk and limbs. A skin biopsy showed perivascular and periadnexal mixed inflammatory cellular infiltrate with fibroplasia. Notably, the dermis also showed squamous epithelial islands, which in foci were noted to be closely associated with eccrine epithelium. This was confirmed with double peroxidase - alkaline phosphatase immunohistochemistry - the eccrine lumina highlighted with carcinoembryonic antigen (polyclonal) and the squamous metaplasia positive for cytokeratin 5/6. Eccrine squamous syringometaplasia was diagnosed. With close clinicopathological correlation, the cutaneous eruption was attributed to tamoxifen. Following discontinuation of the drug, the eruption resolved. Eccrine squamous syringometaplasia has been reported to occur in association with diverse conditions, including skin ulcers, burns and as a cutaneous adverse drug reaction, most commonly to chemotherapeutic drugs. This is believed to be the first report involving tamoxifen.
