BACKGROUND: The mortality rate due to Acinetobacter baumannii nosocomial meningitis (ANM) is high. OBJECTIVE: The aim of this study was to evaluate the factors that have influence over the outcomes in ANM patients. METHODS: A retrospective analysis of 22 cases of ANM was conducted in a hospital with high incidence of multidrug resistance. RESULTS: The mean age of patients was 43 years (21 to 91) and 54.5% were male. All ANM cases occurred within 60 days of admission and the mean duration of illness was of 18.2 days. All cases were associated with previous neurosurgical procedures: elective surgery (27.2%), external shunt (54.4%) and emergency surgery due to trauma (18.1%). Imipenem resistance was observed in 40.9% of cases, but ampicillin/sulbactam resistance was lower (27.2%). The mortality rate of ANM patients was of 72.7%. The only risk factor associated with mortality was inappropriate therapy within five days after CSF collection. All patients who survived the meningitis episode had received appropriate therapy, in contrast to only 69.2% of those who did not survive (OR = 5.15; IC = 0.45-54.01). CONCLUSIONS: The high mortality rate observed in our study suggests the need for aggressive empirical treatment with addition of drugs, including intrathecal therapy, where multi-resistant A. baumannii is endemic

Apresentamos um caso de neuralgia do trigêmeo com investigação radiológica de ressonância magnética (RM) e tomografia computadorizada apresentando resultado normal. A dor não apresentou alívio com carbamazepina, sendo indicado descompressão microvascular do trigêmio. Passados dois meses, o paciente queixava-se de dor com intensidade similar à do pré-operatório. Nova RM mostrou lesão expansiva no cavo de Meckel, a qual foi tratada cirurgicamente por abordagem extra-dural. O exame anatomopatológico foi compatível com melanoma primário. O seguimento radiológico, após seis meses da cirurgia, não apresentou anormalidades.

We present a case of trigeminal neuralgia with cranial normal magnetic resonance image (MRI) and computed tomography. The pain was not relieved by carbamazepine and microvascular decompression surgery was done. After two months the pain was similar to the condition before surgery. At this time, MRI showed an expansive lesion in Meckel's cave that was treated with radical resection by extra-dural approach. The pathologic examination revealed a primary melanoma. The follow-up after six months did not show abnormalities.

Metástases para a coluna vertebral frequentemente causam destruição óssea gerando instabilidade e compressão neural. A abordagem cirúrgica permite ressecção tumoral ampla e descompressão direta do tecido nervoso. Para pacientes com expectativa de vida não muito prolongada, a substituição do corpo vertebral por polímero de metilmetacrilato pode ser utilizada, havendo distribuição adequada da carga axial sobre a coluna vertebral. A técnica descrita neste estudo permite que ocorra estabilização da coluna vertebral de forma imediata proporcionando um meio de proteção das estruturas neurais. Os pacientes toleraram bem esse procedimento e foram capazes de deambular sem auxilio de órteses.

Metastases to vertebrae often cause bone destruction leading to instability and neural compression. Anterior surgical approaches allow tumor resection and direct neural decompression. For patients with a short life expectancy, vertebral body replacement with methyl-methacrylate polymerized in situ can be used for load sharing in the axial plane. Screws hung from the rod into the corpectomy site are incorporated into the acrylic cement. The technique described in this article allows for immediate spinal stabilization and provides a protective environment for the neural elements. All the patients tolerated the procedure well and were able to ambulation without an orthoses.
