N-terminal pro-brain natriuretic peptide predicts hospitalization for ischemic stroke in Japanese hemodialysis patients

Clinical and Experimental Nephrology - The association between N-terminal pro-brain natriuretic peptide (NT-proBNP) and stroke in Japanese hemodialysis (HD) outpatients is unclear. Therefore, in...     

Prognostic factors in the treatment of hepatocellular carcinoma with transcatheter arterial embolization and arterial infusion.

From January 1986 to December 1988, a prospective trial of transcatheter arterial treatment was carried out for hepatocellular carcinoma (HCC). Two hundred seventy-five patients were included. Okuda's staging system was employed. Patients with Stage I and II HCC were treated by transcatheter arterial embolization (TAE) with a gelatin sponge containing an anti-cancer agent (protocol 1a); a gelatin sponge and iodized oil mixed with an anti-cancer agent (protocol 1b); or iodized oil mixed with an anti-cancer agent (protocol 2). Patients with Stage III HCC were treated with iodized oil with anti-cancer agent (protocol 2). As an exception, patients with an unsuccessful superselective catheterization into the proper hepatic artery by Seldinger technique or obstruction of the main trunk of the portal vein were treated with percutaneous transcatheter arterial infusion into the common hepatic artery regardless of stage (protocol 3). Tumor type and extension, area of tumor involvement, portal vein involvement, method of treatment, and presence of ascites and icterus were found to be the significant factors for an initial response to therapy. Treatment method was the most important factor. Respective survival rates at 1 and 2 years were 70.9% and 55.3% for protocol 1a; 62.3% and 43.8% for protocol 1b; 37.8% and 18.3% for protocol 2; and 16.5% and 0% for protocol 3. Many factors proved to significantly influenced prognosis; however, tumor type had the most important prognostic significance followed by AFP value, ascites, treatment protocol, and area of tumor involvement.     

The immunopathology of olfactory nerve injury and hemorrhage in gerbils

Patients with head injury may experience olfactory dysfunction. Unfortunately, little is known about changes in the olfactory neuroepithelium caused by intracranial olfactory nerve injury and hemorrhage. We performed olfactory nerve section or bulbectomy in 53 Mongolian gerbils and subjected the olfactory neuroepithelium to immunohistochemical analysis. A decrease or disappearance of the antiserum to an olfactory marker protein containing olfactory receptor neurons was evident in the sectioned group. Degeneration of the olfactory neuroepithelium contralateral to olfactory nerve injury was also noted in animals with perineural hemorrhage. These findings suggest that olfactory dysfunction may occur not only with nerve injury but also secondary to intracranial hemorrhage.     

Pulmonary vascular involvement in neoplastic angioendotheliosis.

Neoplastic angioendotheliosis has rarely been described as a respiratory disease. A patient is described with pulmonary vascular involvement induced by neoplastic angioendotheliosis in pulmonary vessels.     

Cervical spinal cord compression in hereditary multiple exostoses

Spinal cord compression is an extremely serious complication of hereditary multiple exostoses (HME). A case of HME with compression of the cervical spinal cord is reported. Complete recovery following surgery was achieved. A review of the relevant literature revealed 51 previous cases of HME with cord/cauda equina compression. Most patients were under 30 years of age with more men affected than women. The family history was positive in 60%. The cervical and thoracic areas were predominantly affected, with the symptoms usually developing slowly. Recovery following surgery is to be expected in the majority of cases. In patients with HME and suffering from neurological symptoms, the possibility of spinal cord compression should be considered. Prompt diagnosis and surgical excision provide the best prognosis.     

Phase I study of E1040, a new parenteral cephem antibiotic

The safety and pharmacokinetics of E1040, a new injectable cephem antibiotic, were evaluated in healthy volunteers. In single-dose studies, 125, 250, 500, 1000 and 2000 mg of E1040 were administered by I.V. infusion over 1 hour. Results of 5 minutes I.V. infusions of 500, 1000 and 2000 mg of the drug were also studied. Plasma concentration-time profiles were well suited to a two-compartment open model. The half-life of elimination from plasma was 1.85 +/- 0.16 hours, and the Cmax and AUC paralleled the doses given. The mean urinary recovery within the first 24 hours was 85.7 +/- 6.43% of the dose. In a multiple-dose study, 2000 mg of E1040 (I.V. over 1 hour) was administered every 12 hours (total 9 times) and no abnormal accumulation of the drug in plasma was observed. There were no significant differences in plasma levels or in urinary recoveries between single- and multiple-dose regimens. There were no subjective or objective abnormal findings definitely attributable to the drug except that one subject given 250 mg over 1 hour reported diarrhea, and another complained of nausea during the infusion of 2000 mg over 5 minutes. From these results E1040 was concluded to be safe and well tolerated.
