[Epidemiological and therapeutic studies on gonorrheal infections--clinical efficacy of T-2588. (Sapporo Clinical Research Group for STD)].

T-2588, a new oral cephalosporin antibiotic, for gonorrheal infections, was administered to 146 patients with gonorrheal infection cases (140 urethritis cases in males, 6 cervicitis cases in females). Twenty three strains (20.9%) out of 110 clinically isolated gonococci were PPNG. The MICs of T-2588 for the clinically isolated gonococci strains showed a distribution peak at 0.025 microgram/ml and ranged between 0.0125 microgram/ml to 0.1 microgram/ml when an inoculum size of 10(6)/CFU/ml was used. The distribution of MICs of PPNG also showed a peak at 0.025 microgram/ml and the maximum MIC was 0.2 microgram/ml, which is one dilution tube higher than the maximum MIC of non-PPNG. The rate of complication by Chlamydia trachomatis was 20.9% in male and 33.3% in female. At the dose of 400 mg given 2 times a day, the efficacy rate for the males on the 3rd and 7th day was 90.5% (efficacy rate against PPNG, 73.3%) and 95.3% (80.0%), respectively. At the dose of 300 mg given 3 times a day, it was 93.3% and 100%, respectively, and at the dose of 600 mg given 3 times a day, it was 100% and 100%, respectively. Therefore, the administration of T-2588 3 times a day resulted in a higher efficacy rate than that given 2 times a day. This effect was extremely marked in the case of patients with PPNG. The best clinical results were obtained at a daily dose of 600 mg t.i.d. Although the female patients were few, in number and no conclusion can be drawn, the best results were obtained with a daily dose of 600 mg t.i.d. (100%). There were three mild side effects (1.7%), which could not be attributed to the administration of T-2588 in the present study. In conclusion, T-2588 can be to be expected sufficiently clinically effective against gonorrheal infections, including PPNG, at a daily dose of 600 mg t.i.d. for 3 days.

[Epidemiologic and therapeutic studies on gonorrheal infections--use of AT-2266--Sapporo Clinical Research Group for STD].

From August of 1982 through February of 1983, the Sapporo Clinical Research Group for STD treated 131 cases of male gonorrheal urethritis at its affiliated clinical facilities in Sapporo City. The therapeutic efficacy of AT-2266 was investigated, together with an epidemiological study on the cases and bacteriological studies on the isolated strains of gonococcus. In addition, a few cases of female gonorrheal cervicitis were treated, and the therapeutic results for 3 of these cases evaluated. AT-2266 was administered at a daily dosage of 600 mg in one dose to 14 patients, 2 doses to 10 patients and 3 doses to 98 patients. At the end of 3 days of this therapy, the gonococci had been eliminated in all of the cases, but there was variation in the status of disappearance of the secretion. The "excellent" efficacy rates for these three regimens were thus 7.7%, 50% and 57%, respectively. These results showed that administration of the total dosage in two or more divided doses maintained higher minimum concentrations of the antibiotic in the blood and the urine, and were thus more clinically beneficial than when the dosage was given as one daily dose. Of the patients who were treated with 600 mg/day of AT-2266 in 3 divided doses, 93 were evaluated for the therapeutic efficacy. At the end of 3 days 57.0% were "excellent" cases, 39.8% were "good" cases and 3.2% were "fair" cases, and at the end of 7 days of therapy, 67 patients were 74.6% "excellent" cases, 23.9% were "good" cases and 1.5% were "fair" cases. The clinical efficacy rate was thus quite high. Those cases in which the secretion and leukocytes had not disappeared from the urine even at the end of the 7 days of therapy were probably cases of mixed infection involving Chlamydia, etc. Eight of the 77 gonococcal isolates (10.4%) were beta-lactamase producers. The MIC of AT-2266 hardly differed with the size of the bacterial inoculum. With an inoculum of 10(6)CFU/ml, the MIC distribution showed two peaks, i.e., at 0.05-0.2 micrograms/ml and 3.16-12.5 micrograms/ml. Only 11.7% of the strains were found to have high MICs. The distribution of these high MICs was found to be unrelated to the ability to produce beta-lactamase. Mild side effects of AT-2266 were seen in 2 out of 128 patients. (1.6%), an extremely low incidence.

[Therapeutic studies on male non-gonorrheal urethritis--use of AT-2266--Sapporo Clinical Research Group for STD].

AT-2266 tablets were administered orally in a daily dosage of 600 mg for 7 consecutive days as treatment of non-gonorrheal urethritis in 106 cases. The therapeutic results in 90 cases were investigated, and a detailed analysis of various background factors was also performed. Most of the patients were between 15 and 35 years old; 11.3% of the patients were between 15 and 19 years old. The source of infection was a "professional" woman such as a prostitute in 37 cases, and a non-professional woman in 53 cases. This is noteworthy because the source is more often a "professional" women in the case of gonorrhea. Bacterial isolates were obtained by culture of the urethral secretions. Most were gram-positive cocci, especially S. epidermidis, but, in 51.7% of the patients, no bacteria could be cultured. The urethral secretion was purulent in 51.9% of the patients, and serous in the remaining 48.1%. The efficacy rates obtained when AT-2266 was administered in a daily dosage of 600 mg (in 3 divided oral doses) for 7 days were as follows. In the purulent secretion group, the 3-day and 7-day therapeutic efficacy (elimination of the secretion) rates were 24.2% and 61.2%. In the serous secretion group, the corresponding efficacy rates were 36% and 71.4%. Thus the therapeutic efficacy was slightly inferior in the purulent secretion group. Oral administration of AT-2266 resulted in side effects in 5 of the patients (5.5%). These side effects consisted primarily of mild gastrointestinal disturbances, which did not require discontinued drug administration.

[Therapeutic studies on chronic prostatitis--use of AT-2266--Sapporo Clinical Research Group for STD].

AT-2266 is a new antibiotic of the pyridone carboxylic acid class which possesses a broad, low-MIC antibacterial spectrum. Therapeutic studies were carried out on the use of this drug in the treatment of chronic prostatitis, and at the same time a pathological analysis was performed on chronic prostatitis. The subjects were 97 chronic prostatitis patients for whom the prostate fluid had been confirmed to contain at least 30 leukocytes per 400-power magnification field. An analysis of the background factors revealed that 71% of these patients had a past history of gonorrheal or non-gonorrheal urethritis. Culture of the prostate fluid yielded gram-positive cocci (S. epidermidis in most cases) in 44.1% of the patients. E. coli was detected in 3.2% of the patients, while the remaining cases gave negative cultures. In 53.9% of the patients who had not been receiving therapy prior to inclusion in this study, the subjective symptoms consisted of urethral irritation or irritation upon urination. In the other patients, the relationship of the complaints to the disease could not be clearly established. In the patients who had been receiving therapy, the majority did not complain of subjective symptoms. AT-2266 was administered in a daily dosage of 600 mg (in 3 divided doses) for 14 days. The therapeutic efficacy was evaluated. At the end of 7 days of AT-2266 therapy, 15.5% of the previously-untreated group and 8% of the previously-treated group were "excellent" cases, and the efficacy rate was 32.8% and 36%, respectively, when the "good" cases were also included. At the end of the full 14 days of therapy, the corresponding efficacy rates were 21.7% and 17.4%, and 54.3% and 56.5%. Considerable improvement was achieved in the subjective symptoms of urethral irritation and irritation upon urination at the end of 7 days of therapy, and the improvement was even greater following the next 7 days of treatment. With regard to the complaints for which the relationship to the disease could not be clearly established, however, the improvement was not very good: there was not much difference between the results on the 7th and 14th days, and the elimination rate even after 14 days was slightly below 30%. In the previously-untreated patients, improvement in leukocyte count in the prostate fluid to 10 or fewer cells per microscopic field was achieved in 15.6% at 7 days and 21.7% at 14 days. As side effects of AT-2266, mild symptoms were observed to occur in only 1.8% of the patients.

[Clinical research on prevention of recurrence of superficial bladder cancer--comparative study on clinical efficacy of bleomycin intravesical instillation and bestatin].

Objectives and methods of the study: Although superficial bladder carcinoma can be surgically eliminated by TUR, recurrence is common. Various attempts have been made to prevent recurrence, but to date an excellent prophylactic method with few adverse reactions has not been established. We conducted a clinical trial study for prophylaxis of bladder carcinoma recurrence, using intravesical instillation of bleomycin, a drug which cause little local irritation, in combination with bestatin, a recently developed immunomodulator. Bleomycin was selected on the bases of experimental results. That is, in beagle dogs, the 1-hour intravesical instillation of bleomycin gained a drug concentration in the bladder wall of 2.08 micrograms/g, which is approximately 4 times higher than that in the intravenous administration of the same dose. The above bleomycin concentration was thought enough to obtain a good clinical effect. A total of 124 patients were randomly divided into the two treatment groups: An only bleomycin intravesical instillation group (60 mg on each treatment day) (58 patients) and a bleomycin with bestatin (60 mg per every day) group (66 patients). In the 2-year follow-up period the recurrence of bladder carcinoma in the two treatment groups was studied. Analysis of non-recurrence rate by life-table method and Kaplan-Meier method: The non-recurrence rate of the bladder carcinoma every three months was calculated by the life-table and Kaplan-Meier methods. The non-recurrence rate in the bleomycin group was approximately the same as the rates in adriamycin or mitomycin reported in the literature. In the bleomycin + bestatin group, the recurrence rates at 9 months and 12 months were significantly (at P = 0.09 and P = 0.08, respectively) lower, and in addition, even the 2-year overall non-recurrence rate curves showed a nearly significant difference (P = 0.179). Especially in the case of papillary pedunculated tumors, the difference in the non-recurrence rate curves was almost statistically significant (P = 0.104). The stratified analysis on the basis of various tumor factors, were as follows. Pathological grade: Although no differences were found in Grades 1 and 2, the bleomycin + bestatin group had a lower recurrence rate in Grade 3 cases (P = 0.1).(ABSTRACT TRUNCATED AT 400 WORDS)

[Epidemiologic and therapeutic study on gonorrheal infections--one shot therapy by aztreonam].

A clinical study of a new monocyclic beta-lactam antibiotic, AZTREONAM (hereafter referred to as AZT) for gonorrheal infections as well as epidemiologic study of gonorrheal infections were made Epidemiology: There was a reflection of the increasing sexual activity of the younger generation; both male and female patients in their twenties were most frequent (male 49.5%, female 43.7%) and the percent of teen age patients was 15.1% (male) and 34.4% (female). Forty two strains (17.2%) out of 244 clinically isolated gonococci were PPNG. Residue of serious secretion was observed in a little less than 20% suggesting a complication by Chlamydia trachomatis. Clinical Result: One shot (1-2 g) therapy by AZT was given to 244 gonorrheal infection cases (212 urethritis cases of males. 32 cervicitis cases of females) with the following highly effective rate. Although beta-lactamase producing MIC of AZT at 10(6) CFU/ml showed a peak of 0.025 microgram/ml and ranged between less than 0.0125 microgram/ml to 0.2 microgram/ml. The time required for the elimination of gonococci was studied by the administration of 1 g and 2 g AZT. Gonococci became extinct in 1-8 hours or 4-4.5 hours on average. The difference between n 1 g and 2 g was scarcely observed. Clinical effect of 1 g one shot and 2 g one shot AZT was examined on the 3rd treatment day for 244 male and females cases. The effective rate was high; 90.7% by 1 g, 97.1% by 2 g for male urethritis, 100% by 1 g also by 2 g for female cervicitis. This therapeutic efficacy was kept even in PPNG, isolated cases. There were two side effects (0.8%), one case each of numbness and, redness and swelling of both hands, out of 244 cases, but both of them were minor ones without clinical complication.

[Clinical experiences of renal and upper ureter stone by extracorporeal shock wave lithotripsy (ESWL). II: 3-month follow-up of cases treated with ESWL].

Fifty three out of 60 cases treated with Extracorporeal Shock Wave Lithotripsy (ESWL), were followed up for 3 months. Forty four of the patients had renal stones (2 had bilateral renal stones, 3 had staghorn calculi, 2 had incomplete staghorn calculi, 10 had multiple renal stones), 2 had the unilateral renal and ureteral stones and 16 had ureteral stone. The stone had been discharged completely within 3 months in 47 cases (86.8%), and residual stones were noticed in 6 cases (11%), two of which had stone discharge after retreatment with ESWL. The other cases are being followed up without further treatment, because the residual sandy stones are thought to be able to be discharged spontaneously.

[Clinical statistics on outpatients at the Urological Clinic of Higashi Sapporo Sanjukai Hospital in 1984].

A statistical study was performed on new outpatients. The total number of new outpatients in 1984 was 6,890 (male: 4,381, female: 2,509) and the male to female ratio was was 1.75:1. They had urogenital diseases definitely diagnosed (5,925), indefinitely diagnosed (325), normal (282), and diseases other than urogenital (358). Thirty percent of the outpatients were referred to by other sources. The number of operations on new outpatients was 191, circumcision, resection of condyloma and vasectomy were representative. The peak of the age distribution was in the thirties for males and in the twenties for females. For the first time in Japan, we treated renal and upper ureteral stones using Extracorporeal Shock Wave Lithotripsy (ESWL) on September 1st 1984. The results of ESWL at our hospital have been satisfactory. A statistical study was made on new outpatients according to the international disease classification. There were 94 malignant (urogenital) tumors (1.5%). The major diseases of the new outpatients were cystitis (acute or chronic: 22.8%), prostatitis (17.0%), upper urinary tract stone (12.9%), benign prostatic hypertrophy (10.1%). In males the major diseases were prostatitis, benign prostatic hypertrophy, upper urinary tract stone, balanoposthitis, gonorrhea, and in female they were cystitis, upper urinary tract stone, pyelonephritis, renoptosis. We conclude that out hospital plays a major role as a private urological hospital.

[Clinical statistics on outpatients during the 5 years period (from 1978 Nov. 1st to 1983 Dec. 31st) after the opening of the Urological Clinic of East Sapporo Sanjukai Hospital (II)].

Our hospital is a private urological hospital. Currently we have 5 full time and 3 part time clinicians, 80 beds (100 beds: in Aug. 1984) and 23 hemodialyzers available for the patients. It is 5 years and 2 months (as of Dec. 31st 1983) since it was established on Nov. 1st 1978. We report the statistics on the new outpatients who have increased remarkably as years go by during this period. The total number of outpatients was 20,837 (male: 12,926, female: 7,911), and the male to female ratio was 1.6: 1. The outpatients who were referred to by other sources, accounted for 35% of the total number. The urogenital diseases definitely diagnosed numbered 15,800 (76%), those indefinitely diagnosed, 2,261 (11%), normal cases 802 (4%), and diseases other than urogenital 1974 (9%). The number of patients admitted was 4,088, and those operated on as outpatients was 887 (inpatients: 2,598). The major operations for outpatients were circumcision and vasectomy. The age range had a peak in the thirties for males and in the twenties for females. The clinical statistics for the outpatients according to the international disease classification are as follows; Cases of diseases transmitted by sexual contact increased year after year. Non-specific infection accounted for about half of the diseases and urogenital malignant tumor accounted for fewer than 2%. The major diseases of the new outpatients showed the same tendency every year, and they consisted of cystitis (18-22%), prostatitis (13-16%), upper urinary tract stone (10%), benign prostatic hypertrophy (8-10%), and balanoposthitis (3-7%).

[Epidemiological and therapeutic studies of gonorrheal infections (I)--clinical efficacy of long acting amoxicillin (L-AMPC)].

During the period from October of 1981 through March of 1982, our research group in Sapporo treated 178 patients (158 males and 20 females) for gonorrheal infections. We performed epidemiological and therapeutic studies on these patients. The youngest of the 158 male patients with acute gonorrheal urethritis was 15 years old. The age distribution was 32 patients (20.3%) under 20 years, 46 patients (29.1%) aged 20 to 24, 34 patients (21.5%) aged 25 to 29, 22 patients (13.9%) aged 30 to 34, 10 patients (6.3%) aged 35 to 39, and 14 patients (8.9%) aged 40 to 54. The fact that 20% of gonorrheal urethritis occurred in youths under 20 years of age, is especially noteworthy. The infection in the teenage boys was found to be picked up mostly from girls met at discos , etc., On the other hand, the patients in their 20s, were infected more frequently by contact with hostesses at massage parlors and bars, these sources making up the majority of male patients who were 25 years or older. These findings are quite interesting because they reflect the socio-economic status of the patients. In addition, the fact that hostesses working at massage parlors are a frequent source of gonorrheal urethritis infections can represent a considerable problem in terms of public hygiene. The 20 female patients with gonorrheal infections were all found to be cases of cervicitis, except for a 1-year-old girl with gonorrheal infection of external genitals. The fact that about half of these female patients were teenagers, aged 16 to 19 years is worth special note. The duration of the latent period was less than 5 days in 83 male patients (58.9%) with urethritis, 6 approximately 10 days in 39 patients (27.7%), 11 approximately 20 days in 13 patients (9.2%), 21 approximately 30 days in 4 patients (2.8%), and over 30 days in 2 patients (1.4%), It can thus be said that the number of cases showing a long incubation period is increasing. The MICs of 154 gonococci strains isolated from the urethral or vaginal discharge were determined. Thirteen (8.4%) of these clinically isolated strains were found to be beta-lactamase producers. When a bacterial inoculation level of 10(6) cells/ml was used in the in vitro MIC determination, the MIC was 1.56 micrograms/ml or higher for 12 of these beta-lactamase-producing strains; the MIC of the 13th strain was 0.78 microgram/ml. At the same time, the MICs of these beta-lactamase-producing strains to doxycycline were also high; 1.56 micrograms/ml or higher.(ABSTRACT TRUNCATED AT 400 WORDS)

Dermatoglyphs of Klinefelter's syndrome.

The dermatoglyphs of 28 Japanese with Klinefelter's syndrome [24 XXY; 2 XXYY; 1 XXXY; 1 XXXXY] were compared with 544 male and 129 female controls. These patients showed high frequencies of fingertip arches pattern, right third interdigital loops, right hypothenar patterns (Lr) and line C terminating 0 in the right hand. The mean summed a-b ridge count of Klinefelter's syndrome patients was significantly lower than that of the male controls. We suggest that an increase in the number of X or Y chromosomes decreased the a-b ridge count in a similar way to the decrease in total finger ridge count.
