Rifampicin in the therapy of gonorrheal urethritis in men]

The therapeutic efficiency of benemycin (rifampicin of Polish production), a semisynthetic antibiotic was studied in 96 male cases with gonorrhea urethritis. The antibiotic was used in a dose of 300 mg every 6 hours (2.1--3gm for the treatment course depending on the desease severity). Observation of the patients for 1--2 months showed etiological recovery in 91 (94.8 per cent) out of 96 patients. Postgonorrhea inflammatory processes were observed in 8.7 per cent of the cases. For studying late results of the treatmant 62 patients were observed for 3 to 12 months. Gonococci were isolated from none of the patients. No side reactions were found in the patients treated with rifampicin.     

Epidemiology of sexually transmitted Chlamydia trachomatis infections in male patients

868 male urethritis patients were studied for the presence of chlamydiae in the 1981-1986 period. 36% of NGU, 31.3% of gonococcal urethritis and 58.8% of PGU urethritis patients presented C. trachomatis infections as detected by cell culture inoculation. Chlamydial infection was recorded more often in the 21-30 years age group (30.8%), in unmarried patients (70.6%), as well as in people with low educational degree (46.6% of cases), 42.3% of the C. trachomatis cases were already confronted with one or more urethritis episodes. 24.7% of patients have been subjected to a previous antichlamydial treatment.     

Oral amoxicillin in acute uncomplicated gonorrhea

Of 53 patients with acute uncomplicated gonorrhea treated with amoxicillin 2 g and probenecid 1 g orally as a single administration, six failed to return for follow-up examination, 10 developed postgonococcal urethritis and one was a treatment failure. The remainder achieved symptomatic cure in an average of 2.3 days. Adverse drug effects were infrequent, mild and transient. We conclude that this dose of amoxicillin and probenecid is a safe and effective treatment regimen.     

PCR for diagnosis of male Trichomonas vaginalis infection with chronic prostatitis and urethritis

The aim of this study was to assess the usefulness of PCR for diagnosis of Trichomonas vaginalis infection among male patients with chronic recurrent prostatitis and urethritis. Between June 2001 and December 2003, a total of 33 patients visited the Department of Urology, Hanyang University Guri Hospital and were examined for T. vaginalis infection by PCR and culture in TYM medium. For the PCR, we used primers based on a repetitive sequence cloned from T. vaginalis (TV-E650). Voided bladder urine (VB1 and VB3) was sampled from 33 men with symptoms of lower urinary tract infection (urethral charge, residual urine sensation, and frequency). Culture failed to detect any T. vaginalis infection whereas PCR identified 7 cases of trichomoniasis (21.2%). Five of the 7 cases had been diagnosed with prostatitis and 2 with urethritis. PCR for the 5 prostatitis cases yielded a positive 330 bp band from bothVB1 and VB3, whereas positive results were only obtained from VB1 for the 2 urethritis patients. We showed that the PCR method could detect T. vaginalis when there was only 1 T. vaginalis cell per PCR mixture. Our results strongly support the usefulness of PCR on urine samples for detecting T. vaginalis in chronic prostatitis and urethritis patients.     

Arterial Hypertension and Ischemic Heart Disease: Comparison in Epidemiological Studies

Forty cases of gonococcal urethritis were treated with oxytetracycline using various dosage schedules; there were 37 cures and three failures. The most convenient and most effective dosage was found to be 250 mg. oxytetracycline, given as a single intramuscular injection of 5 c.c.A series of 40 patients with non-gono-coccal urethritis was also collected. Two cases of urethritis due to Trichomonas vaginalis and two due to Candida albicans were removed from the series. Of the 36 cases which remained, cure was obtained with the use of oxytetracycline in different dosages in 30 cases; six cases were failures. The dosage which gave the best result in the therapy of non-gonococcal urethritis was 250 mg. oxytetracycline (5 c.c.), given as a single intramuscular injection, plus 250 mg. orally, four times a day for four days.The effectiveness of oxytetracycline in the treatment of urethritis has not decreased.     

Efficacy of meropenem in the treatment of severe complicated urinary tract infections]

The clinical and bacteriological efficacies of meropenem in the treatment of 12 patients with urinary tract infection were studied. In 8 patients the drug was administered intravenously in a dose of 1 g every 8 hours and in 4 patients with the creatinine clearance below 50 ml/min it was administered in a dose of 1 g every 12 hours (the treatment course of 7 to 10 days). Meropenem was used in the monotherapy. Severe complicated urinary tract infections were mainly observed in the patients with long-term urolithiasis, subjected to repeated surgical interventions and isolating as a rule polyresistant strains of Pseudomonas aeruginosa and E.agglomerans as the pyelonephritis pathogens at a titre of 5 x 10(5)-5 x 10(8) microbial cells per 1 ml of the urine susceptible to meropenem in 80 to 96 per cent of the cases. The clinical efficacy of the drug was stated in all the patients while the bacteriological efficacy amounted to 88.9 per cent.     

Comparison of amoxicillin and ampicillin in single-dose oral treatment of males with gonococcal urethritis

Amoxicillin in single oral doses of 2.0 g, 2.0 g plus 1.0 g probenecid, or 3.0 g was compared with ampicillin 3.5 g plus 1.0 g probenecid in the treatment of 203 males with uncomplicated acute gonococcal urethritis. Cure rates above 95% were produced by all treatments except the 2.0-g amoxicillin dose, which cured 89% of patients. Of 198 pretreatment gonococcus isolates tested by an agar dilution technique for susceptibility to penicillin G, ampicillin and amoxicillin, over 50% showed relative resistance (MIC > 0.06 μg/ml) to the antibiotics. However, amoxicillin was somewhat more active against isolates showing considerable resistance (MIC ≥ 1.0 μg/ml) to penicillin G or ampicillin. Adverse effects of amoxicillin were few: two patients reported transient nausea and six noted short-lived diarrhea. No hypersensitivity reactions were observed.     

Cefonicid as Therapy for Uncomplicated Gonococcal Urethritis Caused by Penicillinase-Producing Neisseria gonorrhoeae

Young men with uncomplicated gonococcal urethritis were treated with 1 gram of cefonicid given intramuscularly plus 1 gram of probenecid by mouth. Of 53 evaluable patients, 33 (62%) had penicillinase-producing Neisseria gonorrhoeae. All but one of these patients were cured. All men who had penicillin-sensitive infections were cured. Cefonicid was highly effective in the treatment of both penicillin-sensitive and penicillin-resistant N gonorrhoeae. Other than moderate pain at the site of injection, there were no adverse side effects. Cefonicid can be added to the group of newer cephalosporins that are effective in the treatment of gonococcal urethritis caused by either penicillin-sensitive or penicillin-resistant strains.     

Treatment of deep vein thrombosis with streptokinase.

From September 1962 to May 1972 145 patients with acute or subacute deep vein thrombosis confirmed by phlebography were treated with streptokinase. During the same period 42 patients considered unfit for thrombolytic therapy were treated with herapin and oral anticoagulants. The results, assessed by repeat phlebography, in 93 of the patients treated with streptokinase were compared with those in 42 patients treated with heparin. The age, sex, and severity of occlusion were roughly similar in both groups. Streptokinase treatment was successful in 42 per cent, partially successful in 25 per cent, and unsuccessful in 32 per cent of the 93 patients compared with none, 10 per cent, and 88 percent respectively in the 42 patients treated with heparin. Streptokinase was more effective when the thrombus was in proximal rather than calf veins. Thrombi of more than six days old were readily lysed. Plasma fibrinogen levels were below 0-8 g/1 (80 mg/100 ml) in nearly all patients successfully treated. The incidence of pulmonary embolism was no greater with streptokinase than with heparin treatment. Only prolonged follow-up would show whether thrombolytic treatment would be effective in preventing late complications of deep vein thrombosis such as chronic venous insufficiency.     

The efficacy of cefepime (Maxipime) in the treatment of abdominal sepsis in surgical patients]

The efficacy of cefepime in the treatment of 46 patients operated for general peritonitis of various genesis and severity (APACHE II not greater than 35) was studied. Cefepime was used in a dose of 2 g administered every 12 hours as slow intravenous infusions in 0.9 per cent sodium chloride solution in combination with metronidazole administered intravenously in a dose of 7.5 mg/kg body weight. The treatment course was 4 to 15 days. 45 patients were given diflucan for the prophylaxis of fungal superinfection, 3 patients were given aminoglycoside antibiotics (netilmicin or amikacin) and 2 patients were given vancomycin per os. The favourable clinical effect of the cefepime therapy was stated in 38 patients (82.6 per cent) including 4 out of 10 patients with initial APACHE II > 15. 101 isolates of aerobic gram-negative and gram-positive microbes from 38 patients treated with cefepime in combination with metronidazole were tested to estimate the bacteriological efficacy of the therapy and it was shown that only 5.9 per cent of them was resistant. The pathogen eradication was stated in 84.2 per cent of the patients.     

TRICHOMONAS URETHRITIS IN MALES

Trichomonas urethritis in the male should be suspected in all chronic cases of urethritis. The diagnosis is easily established by the hanging-drop method of examining the urethral discharge, or the first-glass urine specimen. Curative treatment is readily accomplished by the use of urethral instillations of Carbarsone suspension using 1 capsule of Carbarsone per ounce of distilled water.     

The use of ampicillin/sulbactam (Unasyn) in treating inflammatory urological diseases

Unasyn is a combination of ampicillin, a bactericidal antibiotic, and sulbactam, an inhibitor of beta-lactamases. It was used in treatment of 36 patients with urogenital infections. The combination was administered intravenously and in the main intramuscularly. The treatment course amounted to 7-10 days. The average daily dose was 6 to 9 g. 22 patients with acute nonocclusive pyelonephritis were treated with the combination and its clinical and bacteriological efficacy was stated in 95 per cent of the cases. An excellent clinical effect of the combination was observed in 6 patients with acute epididymitis. A clinical improvement was also observed in the treatment of the patients with acute prostatitis and chronic renal infections. Unasyn proved to be a highly efficient antibacterial combination with regard to gram-positive flora and colon bacilli as representatives of gram-negative organisms. Satisfactory results were also stated in the treatment of infections caused by Proteus spp. Complete elimination of the pathogen was achieved in 57.7 per cent of the cases. No adverse reactions to Unasyn except pain in the site of the injection were recorded.     

The clinical and economic efficacies of short courses of azithromycin in acute sinusitis]

A randomized study of a 3-day course of azithromycin therapy (500 mg once daily) vs. a 10-day course of co-amoxiclav therapy (625 mg thrice daily) in patients with acute sinusitis was performed with an account of the GCP criteria. One hundred patients in 2 groups each of 50 persons were enrolled. The estimates of the patient body temperature, headache, pain on palpation in the area of the accessory nasal sinuses, nasal cavity stuffing, nasal discharge nature and the nose mucous membrane appearance were recorded prior to the treatment, in 72 hours and on the 10th-12th and 26th-30th days of the treatment. The microbiological analysis of the punctate from the accessory nasal sinuses was undertaken before the antibiotic therapy and 72 hours after its start. The economic analysis included the cost of the antibiotic therapy course, hospitalization term, medical manipulations and laboratory tests as well as the cost/efficacy index. The frequency of the relapses within 6 months after the cure was estimated in the two groups compared. In 72 hours and on the 10th-12th days after the treatment start the efficacy of azithromycin was significantly higher than that of co-amoxiclav. The cure was stated in 41 (82 per cent) and 26 (52 per cent) patients on the 10th-12th days, in 6 (12 per cent) and 21 (42 per cent) patients the improvement was stated and the fail was stated in 3 (6 per cent) and 2 (4 per cent) patients respectively. The efficacy of the drugs on the 26th-30th days after the treatment start did not differ. The isolates of Staphylococcus aureus and Streptococcus pyogenes were the main pathogens. The bacteriologic eradication was recorded in 29 (90.6 per cent) patients treated with azithromycin and only in 18 (69.2 per cent) patients treated with co-amoxiclav. Adverse reactions and relapses of the disease within 6 months after the cure were more frequent in the patients treated with co-amoxiclav. The cost of the azithromycin therapy was significantly lower. It was shown that the shortened course of the azithromycin therapy provided earlier cure of the patients with acute sinusitis, better tolerance of the drug, less frequent adverse reactions, lower cost as compared to the use of co-amoxiclav and no relapses.     

A retrospective study of 932 second trimester terminations using gemeprost (16,16 dimethyl-trans delta 2 PGE1 methyl ester).

A retrospective study of 932 second trimester terminations between 12-27 weeks gestation was carried out to determine the efficacy of gemeprost for second trimester termination. A single course of 5 x 1 mg gemeprost pessaries was administered every three hours. If abortion had not occurred after the first course of pessaries, a further course of 5 x 1 mg pessaries was administered. Intravenous oxytocin was administered after 36 hours if abortion had not occurred. Eighty per cent and ninety five per cent of patients aborted within 24 and 48 hours respectively. Of the remaining 5 per cent of women, 3 per cent aborted with escalating doses of oxytocin. In the remaining 18 (2 per cent) women, the pregnancies were electively terminated with an alternative method. The median induction-abortion interval was 18.0 hours and 15.0 hours in nulliparous and parous women respectively (P less than 0.0001). The number of pessaries required to induce abortion was not influenced by parity. Significantly more parous women bled more than 500 ml. The incidence of pelvic sepsis (0.1 per cent) and cervical tear (0.1 per cent) was low. Twenty six per cent of women had diarrhoea and 23 per cent vomited following administration of prostaglandin. This study confirmed the efficacy of gemeprost for second trimester termination of pregnancy. This method of termination is safe, non-invasive, simple and has a low complication rate.     

Clinical use of rubomycin in neuroblastoma in children]

The results of treatment of 23 children at the age of 7 months to 11 years suffering from neuroblastoma are presented; 22 patients with tumors, relapses or metastases were subjected to the treatment and 1 child was treated prophylactically after radical operation. Four patients were subjected to roentgen therapy in addition to the treatment with rubomycin. The antibiotic was administered intravenously in doses of 0.7--1.5 mg/kg in 1--3 days or daily. The caurse dose (3--12 mg/kg) was determined by the treatment efficiency and the side reactions. The objective effect was observed in 68 per cent of the patients, including the pronounced objective effect (marks 3 and 2) in 41 per cent of the cases. Leucopenia (less than 4000 cells in 1 mm3 of the blood). thrombocytopenia, vomiting (or nousea) and changes in the ECG were registered in 20 (87 per cent), 4,9 and 2 patients respectively. When the results of the treatment were positive, repeated courses of the therapy within 1.5--2 years were carried out; 18 patients died within 4 months to 2 years after the first course of the treatment with rubomycin because of the disease development. No signs of the disease were observed in 4 children with in 3--6 years of observation.     

Intralymphatic administration of antibiotics in the complex treatment of suppurative complications in patients with neurosurgical pathology

The efficacy of endolymphatic route of gentamicin and ceporin administration was studied in 89 patients with neurosurgical pathological processes complicated by acute pneumonia (80 patients) and meningoencephalitis (9 patients) usually after ineffective antibiotic therapy according to the routine methods. The antibiotics were used in accordance with the antibiograms of the causative agents isolated from the bronchial tree or CSF. The endolymphatic use of gentamicin or ceporin once a day in doses of 80 mg or 1 g respectively provided rapid sanation and arresting of the inflammatory foci, lowering of the intoxication level, more rapid promotion of the positive time course of the clinico-roentgenological and laboratory indices and decreasing of the recovery periods by 1.5-2 times in 86 per cent of the patients with pneumonia. The endolymphatic administration of gentamicin in a dose of 80 mg twice a day or ceporin in a dose of 1 g twice a day allowed one to maintain the antibiotic therapeutic levels in the cerebrospinal fluid and to obtain satisfactory clinical results in the combined treatment of meningoencephalitis. The endolymphatic administration of the drugs was well tolerated by the patients and no adverse reactions were observed. This route of administration of antibiotics and in particular broad spectrum antibiotics may be recommended for urgent antibacterial therapy of especially severe neurosurgical patients with pyo-inflammatory complications and patients who did not respond to the routine antibiotic therapy.     

Effects of corticosterone on protein, RNA, DNA and tubulin contents in developing male and female rat brains

The effects of corticosterone treatment on chemical components and tubulin content were studied in the cerebrum, cerebellum and hypothalamus from male and female rats during early life. A dual effect of corticosterone treatment was observed in the cerebellum during the course of growth. In the cerebellum from 10-day-old rats, total soluble protein. DNA, and tubulin content (mg per g wet tissue) increased in the hormone-treated male organ, but RNA, DNA, and tubulin content (mg per g wet tissue) increased in the hormone-treated female. On the other hand, the cerebellum from 20-day-old rats, RNA and tubulin content (mg per g wet tissue) and relative tubulin content (mg per g total protein) decreased in the hormone-treated male organ, but the female cerebellum exhibited a decrease in total protein and tubulin content (mg per g wet tissue), and relative tubulin content after corticosterone administration. Only a few effects of the corticosterone treatment were observed in the cerebrum and hypothalamus from both sexes. It is likely that corticosterone has marked effects on the cerebellum among the three brain-regions in early life, and the dual effect of the hormone in the cerebellum appears to be due to the different responsiveness in the developmental stages of nerve cells, at which the treatment was started.     

A trial of using timentin (ticarcillin/clavulanate) in treating abdominal surgical infection]

Efficacy of timentin was studied in the treatment of 19 patients with peritonitis of various etiology and clinical and laboratory signs of systemic inflammatory reaction characteristic of abdominal sepsis. The clinical and bacteriological effects were recorded in 84.2 and 87.5 per cent of the cases respectively. The drug was administered intravenously dropwise for 30 minutes in a dose of 3.1 g every 4 hours. The treatment course was 4-11 days. The treatment failed in 3 patients. One of them had general peritonitis of gynecological etiology. In the other no significant regression of abdominal sepsis was observed, Pseudomonas aeruginosa strains were isolated from the abdominal cavity, the antibiotic was changed, still incurable polyorganic insufficiency developed and the patient died. The third patient had perforation of the large intestine due to tumor. No adverse reactions to the use of timentin in any of the cases was observed.     

Clinico-laboratory basis for the endolymphatic use of beta-lactam antibiotics in pulmonology

Clinical efficacy and effect of cefuroxime, claforan and pentrexyl used endolymphatically were studied in 85 patients with acute abscess forming and persisting pneumonia. Previous routine antibiotic therapy in these patients was little effective. Administration of the antibiotics into the peripheral lymph nodes provided blocking of the lymphagenic pathway for the infection due to high levels in the lymphatic system. Endolymphatic use of cefuroxime and claforan resulted in a significant improvement of the functions of the T- and B-immunity systems and the indices of natural resistance. The levels of the autoimmune reactions and sensitization to the bacterial antigens decreased. Endolymphatic use of cefuroxime and claforan once every 3 days provided recovery of 9 2.8 per cent of the patients, the treatment periods being decreased 2.5--3 times. Intravenous administration of the drugs according to the routine schemes, endolymphatic use of pentrexyl (5 g once every 3 days) and endolymphatic administration of cefuroxime in a single dose followed by intravenous therapy was less effective. The efficacy of pentrexyl increased, when it was used endolymphatically in combination with lysozyme. Endolymphatic use of claforan in doses of 2--3 g once every 3 days (3--4 infusions during the treatment course) was most effective.
