Isolation of Enterococcus faecalis clinical isolates that efficiently adhere to human bladder carcinoma T24 cells and inhibition of adhesion by fibronectin and trypsin treatment.
The adherence of Enterococcus faecalis strains to human T24 cells was examined by scanning electron microscopy. Five highly adhesive strains were identified from 30 strains isolated from the urine of patients with urinary tract infections. No efficiently adhesive strains were found among the 30 strains isolated from the feces of healthy students. The five isolated strains also adhered efficiently to human bladder epithelial cells. Analysis of restriction endonuclease-digested plasmid DNAs and chromosome DNAs showed that the five strains were different strains isolated from different patients. The adhesiveness of these strains was inhibited by treatment with fibronectin or trypsin, implying that a specific protein (adhesin) on the bacterial cell surface mediates adherence to fibronectin on the host cell surfaces, and the adhesin differs from the reported adhesins.

[Clear cell sarcoma extending into the inferior vena cava].
A 6-year-old boy who had been diagnosed as having Wilms tumor at the prior hospital was admitted to our hospital for investigation of a right flank mass and macrohematuria in October 1990. Magnetic resonance imaging showed Wilms tumor of the right kidney extending into the inferior vena cava. Right radical nephrectomy, lymphadenectomy and thrombectomy were done on October 30th, 1990. Pathological findings indicated clear cell sarcoma of the kidney. One week after the operation, radiotherapy and chemotherapy with actinomycin D (ACTD), vincristine sulfate (VCR), doxorubicin hydrochloride (DXR) and cyclophosphamide (CPM)) were started according to the protocol by National Wilms Tumor Study (NWTS) III. However, he died of bone metastases and pneumomycosis on October 13th, 1992. Clear cell sarcoma of the kidney (CCSK) is a rare tumor accounting for about 4-5% of Wilms tumors. This is the first report on CCSK with tumor thrombus in Japan.

[Concentrations of new quinolone agents in serum and prostate tissue].
Twenty five patients with benign prostate hypertrophy were administered ofloxacin (OFLX) simultaneously with norfloxacin (NFLX) in 6 patients, ciprofloxacin (CPFX) in 10, tosfloxacin (TFLX) in 5 and enoxacin (ENX) in 4 patients. The dose of these new quinolones was 100 mg (except 150 mg of TFLX). Their concentrations in the serum and the prostate tissue were measured by high performance liquid chromatography (HPLC). The serum concentration of OFLX was significantly higher than that of NFLX, CPFX, TFLX or ENX. The prostate tissue concentration of OFLX was significantly higher than that of CPFX or TFLX. The ratio of tissue versus serum concentration of each new quinolone agent was not significantly different. The high OFLX tissue concentration appeared to be caused by the high serum concentration.

[Age-related changes in the size and shape of the prostate observed by transrectal ultrasonography].
To elucidate the change with aging in prostatic morphology, 447 cases without acute diseases and prostate cancer of the first visit from January 1988 to December 1990 were examined by transrectal ultrasonography. Total weight of the prostate, area of maximum section, lateral and anteroposterior diameter on the maximum section and supero-inferior diameter were evaluated. The total weight of the prostate was not found to be correlated with aging. The total weight of the prostate showed a high variation with aging. Prostate growth with more than 30 g was greater in the fifties and increased gradually thereafter. Similar findings were observed for antero-posterior diameter on the maximum section and supero-inferior diameter. With aging, the total weight of the prostate in 20-30% of the patients showed an increase while in 30-40% of the patients, no increase. The total weight of the prostate increased in the fifties with subsequent gradual increase in the sixties. According to prostate shape, antero-posterior diameter on the maximum section and supero-inferior diameter was related to the weight of the prostate.

[Clinical evaluation of Augpenin (clavulanic acid-ticarcillin) in urinary tract infections: especially against beta-lactamase producing strains].
Augpenin contains ticarcillin (TIPC) and clavulanic acid (CVA), at a ratio of 15:1. The beta-lactamase inhibitor, CVA, has been added to protect the TIPC from inactivation by beta-lactamase. To investigate the drug efficacy and safety against urinary tract infections (UTI), Augpenin was administered to 33 patients with chronic complicated UTI and 7 patients with acute pyelonephritis. Thirty two cases were evaluable by the UTI criteria. Excellent results were obtained in 6 of the cases of acute pyelonephritis, and moderate results in 1 case, with an overall effectiveness rate of 100%. Excellent results were obtained in 14 of the cases of chronic complicated UTI, moderate results in 9 cases, and poor results in 2 cases, with an overall effectiveness rate of 92%. No adverse reactions were noted, but a transient elevation of glutamic oxaloacetic transaminase and glutamic pyruvic transaminase levels was observed in 2 cases.

[A case of neuroleptic malignant syndrome with acute renal failure].
Neuroleptic malignant syndrome is a potentially lethal side effect of neuroleptic drugs, characterized by fever, muscle rigidity, autonomic dysfunction, and altered consciousness. A 50-year-old female hospitalized three times in the past for psychiatric treatment was admitted to Umayabashi Hospital for treatment of a relapse of a schizophrenic psychosis. She had received 50 mg of chlorpromazine and one tablet of Vegetamin-A (chlorpromazine 25 mg, promethazine 12.5 mg, phenobarbital 40 mg). Approximately 24-36 hours later, the patient became febrile and lost consciousness, and eight days later, acute renal failure occurred with muscle rigidity. She was transported to Maebashi Red Cross Hospital to receive hemodialysis. On admission, the laboratory studies showed high levels of serum creatine phosphokinase, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, creatinine and blood urea nitrogen. She underwent hemodialysis for treatment of acute renal failure and recovered from it after 16 sessions of hemodialysis.

[Clinical effect of Cernilton in chronic prostatitis].
Twenty-five patients with chronic prostatitis were given Cernilton tablets. Improvement of subjective symptoms and objective findings was noted in 96.0% and 76.0% of the cases. Sonographic findings in the prostate showed 33-100% improvement in four objective items. No side effects were observed in any case after Cernilton medication. Cernilton was judged to be an effective drug for chronic prostatitis.
