Three-day and ten-day chemotherapy for urinary tract infections in general practice.

The length of a course of antibiotic treatment for urinary tract infection varies with the habits of the prescriber. Many patients do not complete a course of treatment once their symptoms have subsided. In uncomplicated urinary tract infection among women seen in general practice a three-day course of amoxycillin was as effective as a 10-day course of the same drug in the same dose. Relief of symptoms was equal in both groups and bacteriuria was eliminated equally successfully in both regimens. There was no significant difference between the two groups in the incidence of side effects from the drugs. The financial saving which could accrue from adopting this therapeutic regimen would be significant.     

Epidemiology of symptomatic infections of the urinary tract in children.

The epidemiology of symptomatic infections of the urinary tract in children and the factors that may alter the risk of infection are not well known. Numbers of children aged under 15 discharged from hospitals because of symptomatic infections of the urinary tract during 1978-84 were obtained from the database kept by the Finnish National Board of Health. Information on continuous treatment for recurrent urinary tract infections was obtained from records kept by the Social Insurance Institution on patients receiving free medicines. The yearly rate of attacks of symptomatic infections/1000 girls decreased significantly from 2.67 (95% confidence interval 2.52 to 2.82) in 1978 to 1.88 (1.76 to 2.01) in 1984. In boys the rate also decreased significantly, from 0.85 (0.77 to 0.93) in 1978 to 0.59 (0.52 to 0.66) in 1984. The period prevalence of free treatment/1000 girls decreased significantly from 7.80 (7.55 to 8.05) in 1978 to 5.30 (5.10 to 5.51) in 1984 but did not change significantly in boys. Although the findings may partly have been caused by changes in policies of admission to hospital, they suggest a decreasing trend in symptomatic urinary tract infections in childhood, which may be associated with changes in the care of infants.     

Management of childhood urinary tract infection in family practice.

To find out to what extent doctors appreciate the potential damage that bacteriuria may cause, we sent questionnaires to 195 family practitioners and trainees in one health board in Northern Ireland. The results of the survey showed that, though doctors seemed to be aware of the risk of renal disease, this was not reflected in practice.     

Reported prevalence of urinary incontinence in women in a general practice

To determine the prevalence of urinary incontinence and other urinary symptoms a questionnaire was sent to all women aged 25 and over and to women under 21 taking oral contraceptives registered with a rural practice (n=937); the questionnaire was completed by 833 women (89%). The overall prevalence of urinary incontinence was 41% (343/833); rates were lower in nulliparous and postmenopausal women (30/181 (17%) and 120/344 (35%) respectively) than parous and premenopausal women (313/652 (48%) and 225/479 (47%) respectively). Incontinence was significantly associated with perineal suturing after childbirth, being present in 201 of 376 (53%) women with sutures compared with 113 of 270 (42%) without. Of the 166 women with a history of minor gynaecological surgery, 100 had symptoms of incontinence, compared with 263 of the 657 (37%) without such a history. Incontinence was not related to type of delivery, and postnatal exercises for the pelvic floor were not beneficial.Inappropriate leakage of urine is perceived by many women as common and therefore not serious; thus it is often not reported to the doctor. Nevertheless, the 6% of women who always require protection against leakage could be helped by treatment.     

Comorbidity patterns in patients with chronic diseases in general practice

Introduction

Healthcare management is oriented toward single diseases, yet multimorbidity is nevertheless the rule and there is a tendency for certain diseases to occur in clusters. This study sought to identify comorbidity patterns in patients with chronic diseases, by reference to number of comorbidities, age and sex, in a population receiving medical care from 129 general practitioners in Spain, in 2007.

Methods

A cross-sectional study was conducted in a health-area setting of the Madrid Autonomous Region (Comunidad Autónoma), covering a population of 198,670 individuals aged over 14 years. Multiple correspondences were analyzed to identify the clustering patterns of the conditions targeted.

Results

Forty-two percent (95% confidence interval [CI]: 41.8–42.2) of the registered population had at least one chronic condition. In all, 24.5% (95% CI: 24.3–24.6) of the population presented with multimorbidity.In the correspondence analysis, 98.3% of the total information was accounted for by three dimensions. The following four, age- and sex-related comorbidity patterns were identified: pattern B, showing a high comorbidity rate; pattern C, showing a low comorbidity rate; and two patterns, A and D, showing intermediate comorbidity rates.

Conclusions

Four comorbidity patterns could be identified which grouped diseases as follows: one showing diseases with a high comorbidity burden; one showing diseases with a low comorbidity burden; and two showing diseases with an intermediate comorbidity burden.     

Pefloxacin pharmacokinetics in pyo-inflammatory diseases of the kidneys and urinary tract]

The factors defining the therapy efficacy were studied in 15 patients with purulent inflammatory diseases of the kidneys and urinary tract. It was found that after the use of pefloxacin, urine bactericidal properties against a pathogen was pH-dependent due to high urinary norfloxacin levels. To predict the efficacy of pefloxacin therapy in renal and urinary diseases, the pathogen should be tested for sensitivity to pefloxacin and norfloxacin within a wide range of pH values. Pefloxacin concentrations correlated with plasma bactericidal properties with respect to the pathogen and was applicable in defining the optimal treatment schemes and doses based on the data of individual drug pharmacokinetics. Monitoring of plasma and urine bactericidal properties in regard to the pathogen proved to be useful in estimating the therapy efficacy.     

Treatment of urinary incontinence in women in general practice: observational study.

OBJECTIVE--To examine what is attainable when treating urinary incontinence in women in general practice. DESIGN--Observational study with 12 months'' follow up. Interview and clinical examination before, during, and after treatment of women seeking help for urinary incontinence in general practice. SETTING--General practice in the rural district of Rissa, Norway. SUBJECTS--105 women aged 20 or more with urinary incontinence. INTERVENTIONS--Treatment with pelvic floor exercises, electrostimulation, oestrogen, anticholinergic drugs, bladder training, and protective pads. MAIN OUTCOME MEASURES--Subjective and objective measures of urinary incontinence; number of patients referred to a specialist. RESULTS--After 12 months'' follow up 70% (69/99) of the women were cured or much better; the mean score on a 100 mm visual analogue scale decreased from 37 to 20 mm; and the proportion of women who were greatly bothered by their incontinence decreased by 62%. 20% (20/98) of women became continent, and the percentage of women with severe incontinence decreased from 64% (63/99) to 28% (27/98). Mean leakage per 24 hours measured by a pad test decreased from 28 g at the start of treatment to 13 g after 12 months. The number of light weight pads or sanitary towels decreased from 1.6 to 0.6 a day. In all, 17/105 (16%) patients were referred to a specialist. CONCLUSIONS--Urinary incontinence in women can be effectively managed in general practice with fairly simple treatment. Most women will be satisfied with the results.     

Roles of uroplakins in plaque formation, umbrella cell enlargement, and urinary tract diseases

The apical surface of mouse urothelium is covered by two-dimensional crystals (plaques) of uroplakin (UP) particles. To study uroplakin function, we ablated the mouse UPII gene. A comparison of the phenotypes of UPII- and UPIII-deficient mice yielded new insights into the mechanism of plaque formation and some fundamental features of urothelial differentiation. Although UPIII knockout yielded small plaques, UPII knockout abolished plaque formation, indicating that both uroplakin heterodimers (UPIa/II and UPIb/III or IIIb) are required for plaque assembly. Both knockouts had elevated UPIb gene expression, suggesting that this is a general response to defective plaque assembly. Both knockouts also had small superficial cells, suggesting that continued fusion of uroplakin-delivering vesicles with the apical surface may contribute to umbrella cell enlargement. Both knockouts experienced vesicoureteral reflux, hydronephrosis, renal dysfunction, and, in the offspring of some breeding pairs, renal failure and neonatal death. These results highlight the functional importance of uroplakins and establish uroplakin defects as a possible cause of major urinary tract anomalies and death.     

Decision making by general practitioners in diagnosis and management of lower urinary tract symptoms in women.

OBJECTIVE--To identify factors influencing decision making by general practitioners in the diagnosis and treatment of lower urinary tract symptoms in women. SETTING--Two suburban London general practices. SUBJECTS--Women presenting to their family doctor with lower urinary tract symptoms. DESIGN--After each consultation the doctor completed a questionnaire on presenting symptoms; clinical examination; investigations undertaken; presence of psychological, social, and menstrual problems; patients'' requests for antibiotics; antibiotic prescribing; knowledge of the patient; attitude towards the consultation; and any other factors assisting in diagnosis and management. Finally, doctors predicted the presence or absence of clinically important bacteriuria. Each woman completed a demographic questionnaire, the 12 item general health questionnaire, and the modified menstrual distress questionnaire, after which each provided a clean catch midstream urine sample. Case notes were examined for information on previous reports of results of urine analysis. RESULTS--When the general practitioners did not know the patients well they were 4.5 times more likely to assume that there was a clinically important infection. When they knew the patient well, they were four times more likely to make a correct prediction of the test result and 12 times less likely to prescribe antibiotics. Doctors were five times more likely to predict the test result correctly in patients from social classes 1 and 2 and were six times more likely to prescribe antibiotics for the older women in the sample. CONCLUSIONS--In women presenting with urinary tract symptoms, these family practitioners seemed to take no particular regard of physical, psychological, or menstrual factors in making their assessments. They were most accurate in their prediction of the result of urine analysis and least likely to prescribe antibiotics when they had a good general knowledge of the patient. Which came first, the diagnosis or prescribing, is difficult to say and probably differed in individual cases. Doctors tended to be more conservative in their management of older women and those whom they knew less well.     

Resistance of urinary tract infection pathogens and choice of antibacterial therapy in pediatric urologic practice]

The data on antibiotic resistance of the main uropathogens isolated from patients with urinary tract infection in an urologic department (319 isolates) and outpatient and diagnostic units (360 isolates) are presented. It was shown that by the antibiotic resistance the Escherichia coli isolates from the urologic department patients and outpatients did not practically differ: 44.1 and 47.8% of the isolates were resistant to ampicillin, 26.7 and 23.4% were resistant to amoxycillin/clavulanate, 28.9 and 24.9% were resistant to co-trimoxazole and 26.5% was resistance to cefuroxime (outpatients). The basic differences referred to Pseudomonas aeruginosa: resistance to ceftazidime in 38.5% of the isolates and resistance to gentamicin in 36.2% of the isolates. The activity against P. aeruginosa could be arranged as follows in the decreasing order: amikacin = meropenem > imipenem > cefepime = cefoperazone/sulbactam > gentamicin = ceftazidime. Resistance of P. aeruginosa to fluoroquinolones (ciprofloxacin and levofloxacin) remained low (7.4 and 8.0% respectively). No ampicillin resistance was revealed in the isolates of Enterococcus faecalis.
