[Recurrence of acute uncomplicated cystitis--criteria for the evaluation of recurrence after antimicrobial chemotherapy].

UNLABELLED: The recurrence of female acute uncomplicated cystitis was investigated clinically. The criteria for the evaluation of recurrences were proposed, as follows; PATIENTS: Target infection is acute uncomplicated cystitis (AUC) which had satisfied the specifications of AUC Criteria by the UTI Committee of Japan and showed the excellent effects of an antimicrobial agent after a definite period of administration. Treatment period: Seven days; after 3 days' administration to evaluate the drug efficacy, patients shall take an additional 4 days' treatment. Interval of follow up proposed was 7 days. Evaluation of recurrence: Parameters of criteria are pyuria and bacteriuria. Recurrence: Pyuria greater than or equal to 10 WBCs/hpf and bacteriuria greater than or equal to 10(4)/ml. Evaluation of the day of recurrence: Evaluation should be made 14 days after the start of treatment. Urine sampling: After 7 days of treatment, midstream urine is collected and in cases with positive findings, catheterized urine should then be collected. Using these criteria it will be possible to evaluate and compare the ability of various antimicrobial agents to cure acute uncomplicated cystitis.

Malakoplakia of urinary bladder following cadaveric renal transplantation.

Malakoplakia of the urinary bladder following cadaveric renal transplantation in a twenty-two-year-old woman is reported. Urinary tract infection with Escherichia coli persisted postoperatively. Three years later, gross hematuria and fever occurred. Yellow-tan mucosal plaques or nodules were observed cystoscopically, and histologic examination revealed malakoplakia of the urinary bladder with characteristic foamy histiocytes containing Michaelis-Gutmann bodies.

[Long-term therapy with Robaveron tablet (KN-7) for urinary disturbance].

Sixteen patients with benign prostatic hypertrophy (BPH, 5 cases) and neurogenic bladder (NB, 11 cases) were treated with Robaveron tablets (KN-7) containing an extract of swine prostate gland 20 mg/T. at the dose of 2 tablets t.i.d. for a long term of 6-33 months. Evaluation of drug efficacy and safety were based on decrease of residual urine, improvement of subjective symptoms, complaints of side effects and clinical laboratory tests recorded every three months. Significant decrease of residual urine rate and good improvement of various subjective symptoms such as difficulty in urination, pollakisuria, urinary incontinence, etc. were obtained and maintained. The overall effectiveness, rated as slightly improved or better on the final evaluation of these cases was 68.8%. No cases of side effects or abnormal changes in the laboratory tests directly due to the test drug were observed. Robaveron tablet is both safe and effective for the long-term therapy of urinary disturbance.

[A case report of infantile testicular cancer: dissection of paraaortic lymph node involvement indicated by gradual rise in serum alpha-fetoprotein after orchiectomy].

We present a case of a 32-month-old boy with teratoma accompanied by yolk sac carcinoma and embryonal carcinoma of the right testicle. To treat the gradual rise in serum AFP value 3 months postoperatively, he received combined chemotherapy including VCR, CPM and ADM followed by bilateral retroperitoneal lymph node dissection. The preaortic lymph node disclosed, pathologically, yolk sac carcinoma and embryonal carcinoma, which demonstrated neither degeneration nor necrosis despite remarkable decrease in serum AFP value after the chemotherapy. The patient had normal AFP value and no evidence of recurrent disease 36 months after the lymph node dissection. We emphasize the discrepancy between the response of the tumor marker after the chemotherapy and the histologic alteration. Furthermore, the management of infantile testicular cancer is discussed.

[Condyloma acuminatum of the urethral in a child: a case report and review of the literature].

A rare case of condyloma acuminatum of the urethral meatus in a male child is reported. The patient was five years old and developed a warty mass on the glans penis. He underwent successful resection with a Nd-YAG laser. Excised specimen showed typical characteristics of condyloma acuminatum on histology. Although the disease is thought to develop by a contact infection of human papilloma virus (HPV), the present case had no history suggesting this pathogenesis. At 4 months after operation, no disease recurrence was seen. A short review of the disease found in younger persons is also presented.

[Study on the detection of bacterial infection in tubeless ureterocutaneostomy].

The presence of bacteria at the renal pelvis and the methods of their detection were studied in 11 patients with catheter-free cutaneous ureterostomy (tubeless ureterocutaneostomy). These patients had had total radical cystectomy due to bladder carcinoma. Of these, 5 patients had single-sided stoma with 9 kidney-ureter units and 6 patients had bilateral stoma with 10 units, excluding 2 ureters because of indwelling catheters. The urine obtained both from the renal pelvis with a single lumen catheter and from the pouch were used in the bacterial culture test and urinalysis. The aseptic swab after touching the skin around the stoma was also cultured for bacteria. Of 19 kidney-ureter units, 9 (47%) were found to have bacteria in urine obtained from catheterization. However, only 2 units (11%) were observed to be accompanied with pyuria. In this method, the rate of bacterial appearance was higher in single-sided stomas than in bilateral ones. There was no statistical correlation between the presence of hydronephrosis and the rate of bacterial appearance. In conclusion, the method of single lumen catheterization might be of great use for analysis of urinary tract infections in patients with such conditions.

[A case of postpartum spontaneous rupture of an angiomyolipoma].

A case of postpartum spontaneous rupture of angiomyolipoma in a 27-year-old woman with the chief complaints of right flank pain and fever was reported. Physical examinations revealed an infant-head sized, hard elastic mass with a smooth surface in the right flank. Laboratory studies showed a decrease of Hb to 9.0 g/dl and Ht to 26.5%, and elevated LDH (2914 IU/l). Angiomyolipoma was suspected with ultrasonography, CT scan and angiography. Transperitoneal right nephrectomy was performed. The right kidney and tumor weighed 1,870 g. Pathological diagnosis also confirmed angiomyolipoma of the kidney. Discussion of the case and a brief review of the literature on spontaneous rupture of angiomyolipoma in the intra- and postpartum are made.

The proteolytic activity of human prostate-specific antigen.

Human prostate-specific antigen has been found to exhibit a mild activity of protease at neutral pH. This finding is based on two observations: a proteolytic activity was always associated with the antigen fractions during purification, and the proteolytic activity and the antigen were precipitated with specific antibody to the antigen. In comparison with physico-chemical and catalytic properties of known proteases, human prostate-specific antigen is a distinct neutral protease.

Maternal hyperthyroidism and congenital malformation in the offspring.

Six hundred and forty-three neonates from mothers with Graves' disease were examined for major malformations of external organs to compare the influence of maternal hyperthyroidism vs. ingestion of methimazole (MMI) during the first trimester on the incidence of congenital malformations. The subjects were divided into four groups according to maternal therapy and thyroid status during the first trimester as follows: (1) infants whose mothers did not receive MMI and were hyperthyroid (Group 1), (2) infants whose mothers did not receive MMI and were euthyroid (Group 2), (3) infants whose mothers received MMI and were hyperthyroid (Group 3) and (4) infants whose mothers received MMI and were euthyroid (Group 4). The prevalence of malformed infants in these four groups was 6.0% (three of 50), 0.3% (one of 350), 1.7% (two of 117) and 0.0% (none of 126), respectively. The incidence in Group 1 was significantly higher than that in Group 2 (P less than 0.01). There was no discernible dose dependency of MMI on the occurrence of malformations. These findings suggest that maternal uncontrolled hyperthyroidism may cause congenital malformations and that the beneficial role of MMI treatment outweighs its teratogenic effect, if any.
