The appropriateness of antimicrobial prescribing habits by resident physicians in a family practice center was evaluated. From a six-month period, 225 antibiotic prescriptions were reviewed retrospectively, in a three-phase study. In the first phase, two physicians determined the validity of the diagnosis and treatment for each case, based on criteria suggested by current literature. In the second phase, the pharmacist investigators compared the prescribed regimens with the established criteria for appropviateness of drug choice, daily dose, dosage interval, and duration of therapy. In the third phase, charts were reviewed to determine if microbial cultures had been ordered. The diagnosis was accepted in 89% of the cases; of those, drug therapy was indicated for 84%, an appropriate drug was prescribed in 89%, daily dose was appropriate in 72%, dosage interval was acceptable in 75%, and duration of therapy was appropriate in 59%. Microbial cultures were commonly ordered for pharyngitis, cystitis, pyelonephritis, and gonococcal urethritis. Cultures were not ordered for tonsillitis, nongonococcal urethritis, prostatis, and pelvic inflammatory disease. The prescribing patterns of a group of family practice residents were found to be in less than full compliance with standards in the literature. However, the importance of this finding is difficult to judge because there have been few such studies in ambulatory care settings and the validity of some of the criteria for appropriateness is not known.

Ureaplasma urealyticum organisms (ureaplasmas), Mycoplasma hominis, M. fermentans, M. primatum, M. Salivarium and M. pneumoniae have been isolated from the genitourinary tract. The first two of these microorganisms are found most frequently. M. hominis is a cause of some cases of postpartum and postabortal fever, acute pyelonephritis and pelvic inflammatory disease. Ureaplasmas have been associated with chorioamnionitis, habitual spontaneous abortion, low birthweight, the urethral syndrome in women, and nongonococcal urethritis (NGU) in men; but the difficulty of proving an etiological relationship is emphasized. However, in NGU there is accumulating evidence to indicate that ureaplasmas cause some cases. Some patients suffering from NGU, from whom ureaplasmas, mycoplasmas and chlamydiae cannot be isolated, respond to tetracycline therapy. This has suggested that a tetracycline-sensitive microorganism might be responsible. In this context, the isolation of a glucose-metabolizing mycoplasma from the genitourinary tracts of 2 of 13 men with NGU is of interest. This mycoplasma, serologically different from all other tested, has the structural and biological features of a pathogenic organism.

Pefloxacin (Abaktal) was used in treatment of 83 patients: 14 patients with acute pyelonephritis, 5 patients with carbuncle of the kidney, 17 patients with postoperative acute pyelonephritis, 3 patients with urosepsis, 7 patients with acute prostatitis, 18 patients with chronic pyelonephritis in the phase of active inflammation, 9 patients with exacerbation of chronic prostatitis, 3 patients with acute cystitis, 2 patients with acute urethritis and 5 patients with epididymo-orchitis. Two dosage forms of pefloxacin were used i.e. tablets of 400 mg and ampoules of 5 ml containing 400 mg of the active substance. The treatment course amounted to 7-14 days. In the patients with inflammatory infectious diseases of the lower urinary tracts (cystitis and urethritis) the treatment course amounted up to 5 days. The results of the treatment with the ampoule solutions were good and satisfactory. With the use of the tablets the results were unsatisfactory in 3 patients (8.1 per cent). Satisfactory bacteriological efficacy of the treatment was stated in 89.5 per cent of the cases. The adverse reactions such as nausea, vomiting, diarrhea and skin eruption were recorded in 5 patients (6 per cent).

Nubian goats were experimentally infected with Corynebacterium renale type II by either the intravenous or intraurethral routes using infection rates of 1.75 x 10(10), 7.08 x 10(19) or 5 x 10(23) organisms. All inoculated goats were anorexic, lost weight and became dull or depressed. Albuminuria, pyuria and epithelial casts were noted in the urine. Following intravenous challenge the animals showed a dose-related elevation of serum ammonia, urea, and creatinine with significant changes in haemoglobin concentration, packed cell volume and leucocyte counts. A mild to severe (sometimes haemorrhagic) cystitis and urethritis and a mild nephrosis were noted post mortem and mucoserous or mucogelatinous non-purulent discharges were present in the renal pelvis. The findings are compared to the naturally occurring C. renale pyelonephritis in cattle and the suitability of the goat as a model for that disease is discussed.

To date transurethral laser ablation of the prostate (TULAP) in benign prostatic hyperplasia (BPH) is the commonest form of transurethral laser surgery. The invention of the so-called "sidefire" laser fibre was the prerequisite condition for effective transurethral laser ablation of the prostate. Since the first transurethral laser ablation in human BPH was performed by Costello in September 1990, a multitude of urologists have adopted this technique. In the meantime, a great many studies have been carried out and a lot of data have been published. The initial, to some extent euphoric, enthusiasm of some urologists as well as some patients, especially in the USA and Europe, has turned into a more critical reflection. There is no doubt at all that TULAP is a feasible alternative treatment method with reasonable results. Especially in the high-risk patient, there is neither severe blood loss nor an uptake of irrigation fluid. It is also beneficial to allow unlimited treatment in patients on anticoagulant medication. Nevertheless, the value of TULAP in comparison to transurethral electroresection of the prostate (TURP), generally accepted as the "gold-standard" in the surgical therapy of BPH, remains unclear. A final assessment will only be possible when further data on mortality, short and long term morbidity and outcome with this method have been presented. Strong evidence exists that the operation can be performed without blood loss and uptake of irrigation fluid. A further advantage seems to be preservation of sexual function, especially anterograde ejaculation in the majority of patients, in comparison to the "gold-standard" TURP. In most studies, the value of TULAP is further compared with regard to the elimination of obstruction by means of pressure-flow-studies. The aspect most frequently neglected by all investigators to date is the frequency and severity of urinary tract infections (UTI) in patients in whom TULAP is performed. Basically, UTI in the form of cystitis, ascending infections such as male adnexitis or pyelonephritis, prostatitis of the remaining parts of the prostate and catheter-induced urethritis are associated with transurethral surgery in general. Certain data indicate an age-related frequency of UTI. From a rate of approximately 1% of UTI in infants, the frequency rises to 30% in the 8th decade of life. According to these data, one can expect that in a study of TULAP in high risk patients, most of whom are elderly, a large number present for surgery with a preexisting UTI. Other data demonstrate that after 4.5 days 50% and more of patients with an indwelling catheter develop an ascending UTI, although a closed urinary drainage system has been used. In most cases enterobacteriaceae, in 80% Escherichia coli, are detected. Especially in TULAP, a period of prolonged catheterisation has to be expected in the majority of patients. The risk of UTI in the perioperative phase is therefore expected to be higher. There are several higher risks and possibilities of complications in transurethral surgery in patients with UTI. Taking this into account, all our patients routinely undergo low dose antibiotic prophylactic treatment. The frequency of infections of the remaining parts of the prostate after prostatic surgery is strongly correlated to the flow characteristics in the prostatic urethra and to the amount of destruction of the prostatic tissue. Here are further reasons for a higher risk of infection after TULAP. Due to the fact that the prostatic tissue is not removed by a clear cut, but coagulated by laser beam, a rough surface due to tissue necrosis results. This is an ideal culture medium for bacteria aggravated by the disturbed laminar flow in the prostatic urethra, which favours an intraprostatic reflux of infected urine. There is evidence that UTI are the most important factor of morbidity during the first weeks after TULAP because of their bothersome symptoms.(ABSTRACT TRUNCATED)

Mycoplasma hominis and Ureaplasma urealyticum can be isolated with considerable frequency from the human urogenital tract and are thought to cause various syndromes such as nongonococcal urethritis, pelvic inflammatory disease, pyelonephritis or infertility. The aim of this study was the evaluation of the presence of different genital pathogens in patients with sexually transmitted diseases (STD) and, in particular, the detection of mycoplasmas in individuals infected with genital microbes and an assessment of the presence of genital microorganisms in patients harbouring Mycoplasma hominis or Ureaplasma urealyticum. Furthermore, the occurrence of mycoplasmas in women with bacterial vaginosis was established. Specimens were collected from a total of 41,980 persons attending the Outpatients' Centre for Infectious Venero-Dermatological Diseases in Vienna from 1994 to 1996. Of all genital pathogens, Ureaplasma urealyticum was cultured most frequently in men and women. Mycoplasma hominis and Ureaplasma urealyticum were detected more often in the vaginal fluid than in the male urethra. By contrast, infection rates with Neisseria gonorrhoeae and Chlamydia trachomatis were higher in men than in women. In both men and women, trichomoniasis increased colonisation with Mycoplasma hominis, while mycoplasmas occurred less frequently together with genital candidiasis. Mycoplasma hominis was cultivated significantly more often in women with bacterial vaginosis than in those without. In contrast to urethral infections in men, cervical infections with Neisseria gonorrhoeae or Chlamydia trachomatis raised the incidence of Mycoplasma hominis in the vaginal fluid.

Bacterial cystitis is the most common bacterial infection occurring in women. Thirty percent of women will experience at least one episode of cystitis during their lifetime. About one third of patients presenting with symptoms of cystitis have upper urinary tract infection. A careful history to identify risk factors for subclinical pyelonephritis is important. Symptoms of chronic cystitis accompanied by sterile urine without pyuria may represent interstitial cystitis. Dysuria may also be the principal complaint of women with vaginitis (infectious, atrophic or chemical) or urethritis. A stepwise diagnostic approach, accompanied by inexpensive office laboratory testing, is usually sufficient to determine the cause of dysuria.

Mycoplasma hominis and Ureaplasma urealyticum are species closely related to urogenital diseases such as pyelonephritis, nongonococcal urethritis, urinary calculi, epididymitis, pelvic inflammation, infertility, abortions and post-delivery fever. They can also cause pneumonia and meningitis in newborn infants. In this paper we used nucleic acid hybridization and polymerase chain reaction to analyze 22 samples from patients with different urogenital symptoms in order to detect mycoplasmas and ureaplasmas. We obtained 10 positive samples and 12 were negative. From positive samples we identified two with Mycoplasma hominis, two with Ureaplasma and six with both species. The results obtained by these molecular techniques were compared with reference methods and we found coincident results in 18 samples, while in four the results were discordant. These discordant findings were not statistically significant.

Clinically, it is important to detect mycoplasmas because these organisms have been implicated in gastric and ovarian cancer, pneumonia, postabortal fever, pelvic inflammatory disease, pyelonephritis, endometritis, urethritis, perinatal mortality, arthritis, spontaneous abortion, infertility and interference with sperm development and they act as cofactors catalyzing the HIV disease state. Recently, the combined polymerase chain reaction and enzyme-linked immunosorbent assay method targeting the consensus DNA of over 15 species of mycoplasmas was shown to be superior for the detection of mycoplasmas. The objective was to determine if there was an association between mycoplasmas and cervical neoplasia. Cervical tissues, histopathologically categorized by cervical intraepithelial neoplasia (CIN) grade, flat or exophytic, and acanthosis or koilocytotic, were used. The results showed that mycoplasmas DNA were present in 21.4% of the condyloma tissues and in 33.3% of condyloma tissues with CIN. In contrast, mycoplasmas DNA were not detected when there were no CIN. The presence or absence of human papillomavirus (HPV) did not make a difference. Mycoplasmas DNA were present in 40.0 and 12.5% of the exophytic and flat condylomas, respectively. A higher percentage of cervical tissues graded with slight koilocytosis had (P = 0.05) mycoplasmas DNA compared with tissues graded with moderate koilocytosis. The detection of mycoplasmas DNA in archived cervical condyloma tissues with CIN corroborated previous reports of an association between mycoplasmas and CIN. However, the association between mycoplasmas and the presence of HPV could not be made in this study.

Urinary tract infections are one of the most common renal diseases sometimes leading to renal injury and in consequence to chronic renal failure. The most frequent causative pathogen responsible for this infection is Escherichia coli. There are several factors which increase the risk of infection including vesicoureteral reflux, cystic renal disease, urinary calculi, obstruction and other anatomical and functional abnormalities of urinary tract as well as neurological bladder dysfunction, long term indwelling catheters, mechanical vaginal diaphragms and intensive sexual intercourse. This paper will highlight general view on the treatment of different manifestations of urinary tract infections including asymptomatic bacteriuria, urethritis, cystitis, prostatitis as well as acute and chronic pyelonephritis. The details of those problems will be elucidated in another paper.
