RESUMO

We report a middle aged man who was admitted with severe necrotising fasciitis following a motor vehicle accident (MVA). Histopathology of the excised tissue suggested mucormycosis while a bone tissue culture revealed fully sensitive Mycobacterium tuberculosis. He received intravenous liposomal amphotericin B combined with multiple surgical debridements and ended with right shoulder disarticulation. In addition he completed a nine months course of anti-tuberculosis treatment. He remained stable one year following his admission. We believe that trauma contributed to both conditions by direct inoculation of fungal spores and through immunological reactivation of old healed tuberculosis focus. This case highlights the importance of considering diagnosis of invasive fungal infections following MVA.

RESUMO

Gastrointestinal basidiobolomycosis (GIB), caused by Basidiobolus ranrum, is a rare fungal infection with a limited geographic distribution. The majority of the cases are reported from the warm areas of Arizona in USA, Saudi Arabia and Iran. We report a middle aged patient who was admitted to hospital with suspected metastatic colonic carcinoma. He presented with constipation, anorexia and weight loss. Computed tomography scan disclosed a mass involving the mid and distal sigmoid colon and hypodense lesion in hepatic segment IV. Excised tissue during a Hartmann's surgery showed an extensive eosinophil-rich transmural inflammation with mural necrotizing granulomas and several broad septated fungal hyphae. He was commenced on voriconazole following surgery. The diagnosis of basidiobolomycosis was established by histopathological examination. Since the diagnosis was not suspected preoperatively tissue culture for fungi was not collected. However molecular testing confirmed the diagnosis of GIB. Therapy involved a combination of surgical resection of the mass and prolonged voriconazole treatment. Increased awareness among physicians is needed for early diagnosis and treatment of GIB.

RESUMO

We report on an elderly male patient with headache and right-side weakness. Imaging studies revealed multiple space-occupying lesions in the parietal and occipital cerebral regions. Biopsy revealed broad aseptate ribbon-like structures branching at right angles, suggestive of mucormycosis. Improvement was observed after medical therapy with 20 weeks of liposomal amphotericin B (5 mg/kg/day) combined with posaconazole, followed by posaconazole (400 mg twice a day) alone for 1 month. The patient recovered without neurological deficits; however, multidrug-resistant bacteraemia and hospital-acquired pneumonia occurred, resulting in death. Nevertheless, our report shows that this lethal fungal infection can sometimes show favourable progress with drug therapy alone.

RESUMO

A 26-year-old woman was diagnosed with and treated for systemic lupus erythematosus (SLE) in 2002. She was admitted 11 years later with nephrotic-range proteinuria and lupus nephritis and received two doses of rituximab after failing on steroids and mycophenolate mofetil. Four months later, she presented with fever and joint pain/swelling. Gram stains, joint aspirates, and blood culture all yielded negative results for bacteria. She was discharged after treatment for a possible flare of lupus, but two weeks later, she presented again with a cough and shortness of breath in addition to the flare symptoms. Synovial fluid Smears, and cultures yielded positive results for Mycobacterium tuberculosis; similarly, sputum polymerase chain reaction test and culture confirmed pulmonary tuberculosis. Tuberculosis is difficult to diagnose in SLE patients; it may present like or precipitate SLE flare. In this patient a presumed SLE flare turned out to be an aggressive miliary, disseminated tuberculosis.

RESUMO

Pulmonary complications, including acute respiratory distress syndrome (ARDS), are well described in P. falciparum (PF) and to a lesser extent in other malaria species. In non-endemic areas, malaria diagnosis may be overlooked; if a thorough travel history is not obtained on all patients with acute febrile illness. Three patients with malaria associated respiratory distress were admitted to our intensive care unit. The diagnosis was delayed; however, all patients received artesunate and intensive therapy with a satisfactory outcome. One patient presented with respiratory disease while the others developed ARDS during or following appropriate therapy. Similarly, level of parasitemia was variable ranging from undetectable to over 5%. Variability in timing and severity of illness is exciting and gives emphasis to the different pathological processes contemplated in this complication.

RESUMO

INTRODUCTION: We evaluated hemodialysis (HD) staff knowledge, adherence to infection control recommendations and seroconversion rates for hepatitis B virus (HBV) and hepatitis C virus (HCV) in 13 centers that continuously provided HD services in Khartoum State between June 2009 and November 2010. METHODS: The knowledge of 182 HD staff members was evaluated by a self-filled questionnaire. Relevant data were obtained from 1011 HD patients by direct interviews and record review. Adherence to infection control recommendations was evaluated by direct observation. RESULTS: HD staff members achieved a median score of 81% in knowledge evaluation (range 44-100%). Better scores were achieved by more experienced staff. We identified serious gaps in knowledge related to the environmental risk of viral transmission. Regular screening by enzyme-linked immunoassay (ELISA) was performed in 46% of centers. Only half susceptible patients were vaccinated against HBV. Staff dedicated for treatment of HBV positive patients were found in only 57% of centers that served such patients. Hand washing recommendations were strictly observed in 15% of centers, disinfection of HD stations between patients was strictly observed in 23% of centers, medications were prepared in a separate area in 8% of centers and delivered separately to each patient in none of the centers. There were 2.5 HCV seroconversions and 0.6 HBV seroconversions per 100 patient-years. Center characteristics that predicted HCV seroconversion were accommodation of HCV-positive patients in the same center, using ELISA for patient screening, and assigning more than 3 patients for one HD nurse. CONCLUSION: There are serious gaps in HD staff knowledge and adherence to infection control recommendations. A structured training program for HD staff members is urgently required.
