RESUMO
Introduction: Mucormycosis is an infection caused by the ubiquitous saprophyte fungi with rapid and aggressive progression, especially in immunocompromised patients. Case report: A 57-year-old woman diagnosed with rhino-orbital mucormycosis presented with decreased renal function after treatment with amphotericin B deoxycholate which was discontinued. Renal function improved after amphotericin B lipid-complex, being also treated with itraconazole, and otorhinolaryngological surgery. Conclusion: The use of Amphotericin B deoxycholate may result in adverse effects. In this situation, Amphotericin B lipid formulation is usually the drug of choice.
Introdução: A mucormicose é uma infecção causada por fungos saprófitos com progressão rápida e agressiva, principalmente em pacientes imunocomprometidos. Relato de caso: Uma paciente de 57 anos, do sexo feminine, com diagnóstico de mucormicose rinorbital apresentou diminuição da função renal após tratamento com anfotericina B desoxicolato que foi descontinuada. A função renal foi recuperada após troca da terapia por anfotericina B complexo lipídico, sendo tratada também com itraconazol e cirurgia otorrinolaringológica. Conclusão: O uso de anfotericina B desoxicolato pode resultar em efeitos adversos. Nestas situações a formulação lipídica da anfotericina B é geralmente a droga de escolha.

INTRODUCTION: The spatial distribution of disseminated histoplasmosis (DH) and acquired immunodeficiency syndrome (AIDS) co-infection in adult residents of Fortaleza, Ceará, Brazil was evaluated. METHODS: Socio-demographic data for the DH/AIDS cases were obtained from a reference hospital, and socio-environmental indicators were obtained from an official Brazilian institute. Kernel analysis and local indicators of spatial autocorrelation (LISA) cluster maps were used to estimate the case density within the city. RESULTS: DH/AIDS cases were concentrated in the Northwestern and Southwestern peripheral areas of the city, related with low human development indices, but different from AIDS cases distribution. CONCLUSION: Risk factors other than AIDS infection must affect histoplasmosis development in this area.

INTRODUCTION: Since the beginning of the HIV epidemic in Ceará, disseminated histoplasmosis (DH) has often been detected among AIDS patients. METHODS: In order to investigate the clinical and laboratory characteristics, evolution and survival of cases of DH/AIDS coinfection, the medical records on 134 cases of DH admitted to a reference hospital in Ceará between 1999 and 2005 were analyzed. RESULTS: Patients with DH presented higher frequency of daily fever, coughing, weight loss, enlarged liver and spleen and acute kidney failure. The diagnosis was made using investigation and/or cultures. At admission, the following were risk factors for death among DH patients: vomiting, dyspnea, respiratory failure, acute kidney failure, hemoglobin < or = 8g/l, urea > or = 40mg/dl and creatinine > or = 1.5 mg/dl. CONCLUSIONS: Patients with DH characteristically presented higher fever, previous hospitalization due to respiratory infection and more clinical complications. Significant anemia and elevated urea were independent risk factors for death among DH patients.

INTRODUÇÃO: Desde o início da epidemia de HIV no Ceará, histoplasmose disseminada tem sido detectada com frequência em pacientes com aids. MÉTODOS: De modo a conhecer características clínico-laboratoriais, evolução e sobrevida da co-infecção HD/AIDS, analisou-se retrospectivamente 134 prontuários casos de HD internados de 1999 a 2005 no hospital referência para HIV no Ceará. RESULTADOS: Pacientes com HD apresentaram maior frequência de febre diária, tosse, perda de peso, hepatoesplenomegalia e insuficiência renal aguda. Diagnóstico foi dado por pesquisa e/ou cultura. À admissão, foram fatores de risco relacionados ao óbito de pacientes com HD: vômitos, dispnéia, insuficiência respiratória e IRA, hemoglobina<8g/L, uréia>40mg/dL e creatinina >1,5mg/dL. CONCLUSÕES: pacientes com HD apresentaram caracteristicamente febre mais elevada, internamentos anteriores por infecção respiratória, mais complicações clínicas e como fatores independentes para óbito, anemia importante e elevação de uréia.

CONTEXT: Rhabdomyolysis is a severe and life-threatening condition in which skeletal muscle is damaged. Acute renal failure due to rhabdomyolysis has been widely described and its main pathophysiological mechanisms are renal vasoconstriction, intraluminal cast formation and direct myoglobin toxicity. OBJECTIVE: To report on a case of acute renal failure (ARF) induced by rhabdomyolysis due to strenuous exercise and alcohol abuse and to describe the pathophysiology of this type of ARF. CASE REPORT: A 39-year-old man arrived at the hospital emergency service with swollen legs and lower extremity compartment syndrome. He was oliguric and had serum creatinine and urea levels of 8.1 mg/dl and 195 mg/dl, respectively. The diagnosis of rhabdomyolysis was made through clinical and laboratory findings (creatine kinase activity of 26320 IU/l). The initial treatment consisted of fluid replacement and forced diuresis. The specific treatment for compartment syndrome, such as fasciotomy, was avoided in order to prevent infection. Partial recovery of renal function was recorded, after ten hemodialysis sessions. Complete recovery was observed after two months of follow-up.

CONTEXTO: Rabdomiólise é uma condição clínica severa e ameaçadora à vida, em que ocorre destruição de músculo esquelético. Insuficiência renal aguda por rabdomiólise já foi bem descrita, sendo os principais mecanismos fisiopatológicos vasoconstrição renal, formação de depósitos intratubulares e toxicidade direta da mioglobina. TIPO DE ESTUDO: Relato de caso e revisão da literatura. OBJETIVO: Relatar um caso de insuficiência renal aguda (IRA) induzida por rabdomiólise devida a exercícios físicos intensos e uso abusivo de álcool e descrever os principais mecanismos fisiopatológicos deste tipo de IRA. RELATO DE CASO: Homem de 39 anos foi admitido na emergência com edema e síndrome compartimental em membros inferiores. Ele estava oligúrico, e os níveis séricos de creatinina e uréia eram de 8,1mg/dl e 195mg/dl, respectivamente. O diagnóstico de rabdomiólise foi obtido através dos dados da história clínica e dos exames laboratoriais (creatinoquinase de 26320 UI/l). O tratamento inicial consistiu em reposição volêmica e diurese forçada. Tratamento específico para síndrome compartimental, como fasciotomia, não foi realizado para que se evitasse a ocorrência de infecções. Recuperação parcial da função renal foi observada após 10 sessões de hemodiálise. Recuperação completa ocorreu após dois meses de acompanhamento.

Two clinical cases of patients who survived after numerous attacks of Africanized bees (600 and 1500 bee stings, respectively) are reported. Clinical manifestation was characterized by diffuse and widespread edema, a burning sensation in the skin, headache, weakness, dizziness, generalized paresthesia, somnolence and hypotension. Acute renal failure developed and was attributed to hypotension, intravascular hemolysis, myoglobinuria due to rhabdomyolysis and probably to direct toxic effect of the massive quantity of injected venom. They were treated with antihistaminic, corticosteroids and fluid infusion. One of them had severe acute renal failure and dialysis was required. No clinical complication was observed during hospital stay and complete renal function recovery was observed in both patients. In conclusion, acute renal failure after bee stings is probably due to pigment nephropathy associated with hypovolemia. Early recognition of this syndrome is crucial to the successful management of these patients.
