Electroencephalographic findings after convulsive seizures due to cerebral arterial air embolism secondary to lung cancer: a case report.

Background: Cerebral arterial air embolism is often associated with an invasive iatrogenic etiology and a high rate of convulsive seizures. There are only a few descriptions of electroencephalogram findings in convulsive seizures due to cerebral arterial air embolism of noniatrogenic etiology. Herein, we describe the case of a patient with lung cancer and convulsive seizures with abnormalities detected on electroencephalogram caused by cerebral arterial air embolism of noniatrogenic etiology.

Acute Bilateral Renal and Splenic Infarctions Occurring during Chemotherapy for Lung Cancer.

We herein report a rare case of acute bilateral renal and splenic infarctions occurring during chemotherapy for lung cancer. A 60-year-old man presented with acute and intensive upper abdominal and back pain during chemotherapy with cisplatin and etoposide for lung cancer. Contrast-enhanced computed tomography (CT) revealed bilateral renal and splenic infarctions.

Immunohistochemical analysis of neuroendocrine differentiation in prostate cancer.

Objective: To clarify the significance of neuroendocrine differentiation in prostate cancer.

Methods: We immunohistochemically examined 96 samples of prostatic cancers obtained from radical prostatectomies using a specific neuroendocrine marker and various neuropeptides, as well as markers for cell proliferation, angiogenesis and androgen-receptor expression.

Results: We frequently found neuroendocrine cells in atrophic glands with or without chronic inflammation in nontumorous tissues.
