Recurrence of Cutaneous Coccidioidomycosis Six Years after Valley Fever: a Case Presentation and Literature Review
Coccidioidomycosis is usually acquired by inhalation of spores of Coccidioides immitis and C. posadasii. The disease ranges from a self-limited acute pneumonia (Valley Fever) to a disseminated disease. We present a 44-year-old healthy male who had patchy hair loss of several months duration resembling discoid lupus. He developed a firm non-scaly red plaque on the right forehead. Initial biopsy showed spongiotic dermatitis, and he was treated with systemic steroids. He then developed forehead and periorbital cellulitis and was treated with systemic antibiotics. A second biopsy showed fungal hyphae, and he was treated with itraconazole 200 mg bid for 4 months beyond clinical resolution. A year later, he presented with intermittent swelling of the right forehead lesion and worsening of the scalp lesions. A forehead biopsy showed interface dermatitis and negative PAS stain for fungi. Scalp biopsy was highly suggestive of discoid lupus and he was started on plaquenil. Many months later, a third biopsy showed fungal infection, and the culture grew C. immitis. He was treated with itraconazole. Retrospectively, the patient gave a history of Valley fever 6 years back when he was in Arizona, USA
Epidemiology and detection of acinetobacter using conventional culture and in-house developed PCR based methods
Summary: Active surveillance cultures for multidrug-resistant (MDR) gram-negative bacteria is one strategy to control outbreaks. The objectives of the study are to evaluate the prevalence of Acinetobacter colonization and to compare conventional culture and in-house developed PCR based method. Swabs were collected from patients transferred from another organization or were admitted to the intensive care units. Swabs were cultured by conventional method and were tested using in-house LightCycler® 2.0 real-time PCR method. Of 449 tested samples, the majority came from cardiac step down unit (188, 42%), male medical floor (80; 18%), and coronary care unit (66; 13.4%). Of the total specimens, 14 (3%) were positive by PCR and 12 (2.6%) were positive by routine cultures. The positivity rates among wounds, respiratory, perineal, and nasal samples were 3.2%, 9.7%, 4.6% and 0.8% respectively. Two positive samples by PCR were negative by routine culture. The overall concordance rate was 99.5% and the positive concordance rate was 85.7%. The current study revealed a low prevalence of MDR Acinetobacter among the studied population. The LightCycler® 2.0 PCR produced comparable positive results to routine cultures. Keywords: Acinetobacter, Surveillance, Epidemiolog
