Case Reports
Clones of Lactobacillus casei and Torulopsis glabrata associated with recurrent abdominal wall abscess.
Infectious disease caused by Lactobacillus sp has not been previously reported in Taiwan. We present a case of recurrent abdominal wall abscess in a chronically ill 36-year-old woman, and review the literature on Lactobacillus infection. Five isolates of L. casei were recovered from blood and pus samples, and two isolates of Torulopsis glabrata were isolated from two blood specimens 3 months apart. ⋯ The abscess was surgically removed because of poor response to 7 months of antimicrobial therapy for the second infectious episode. Recurrent Lactobacillus infection can occur in chronically ill or immunosuppressed patients. Treatment of these infections may require a longer duration of antibiotic therapy, or surgical intervention.

Limbic encephalitis is an unusual presentation of paraneoplastic syndrome. We report a case of small cell lung carcinoma associated with limbic encephalitis. A 67-year-old man presented with convulsions, memory impairment, and neuropsychiatric disturbances as initial symptoms. ⋯ A follow-up computed tomography scan of the head showed no evidence of intracranial metastasis 7 months after the diagnosis of cancer. Limbic encephalitis may be an initial manifestation of lung cancer. Greater awareness for diagnosis and early treatment of the primary tumor offers the best chance for improvement in patients with lung cancer presenting with limbic encephalitis.

Various types of brain tumors may cause hemorrhage. The purpose of the study was to examine the clinical relevance of tumor hemorrhage and the hemorrhagic mechanism from the pathologic viewpoint. We retrospectively reviewed 761 consecutive brain tumor cases according to clinical, operative, and pathologic records. ⋯ In 72.7% of gliomas with hemorrhage, hematoma appeared within the tumor, and 75% of metastatic brain tumors with hemorrhage were intracerebral hemorrhages around the borders of the tumors. The highest hemorrhage rate for primary brain tumors occurred in pilocytic astrocytomas, while the highest hemorrhage rates in secondary tumors occurred in metastatic thyroid papillary carcinomas and hepatocellular carcinomas. In our pathology study, increasing intratumor vascularization with dilated, thin-walled vessels and tumor necrosis were the most important mechanisms of hemorrhage.
