Abstract
Urinary tract infections (UTIs) are frequently encountered in clinical practice and most commonly caused by Escherichia coli and other Gram-negative uropathogens. We tested RapidBac, a rapid immunoassay for bacteriuria developed by Silver Lake Research Corporation (SLRC), compared with standard bacterial culture using 966 clean-catch urine specimens submitted to a clinical microbiology laboratory in an urban academic medical center. RapidBac was performed in accordance with instructions, providing a positive or negative result in 20 min. RapidBac identified as positive 245/285 (sensitivity 86%) samples with significant bacteriuria, defined as the presence of a Gram-negative uropathogen or Staphylococcus saprophyticus at ≥10(3) CFU/ml. The sensitivities for Gram-negative bacteriuria at ≥10(4) CFU/ml and ≥10(5) CFU/ml were 96% and 99%, respectively. The specificity of the test, detecting the absence of significant bacteriuria, was 94%. The sensitivity and specificity of RapidBac were similar on samples from inpatient and outpatient settings, from male and female patients, and across age groups from 18 to 89 years old, although specificity was higher in men (100%) compared with that in women (92%). The RapidBac test for bacteriuria may be effective as an aid in the point-of-care diagnosis of UTIs especially in emergency and primary care settings.

A comprehensive assessment of environmental exposures among 1000 North American patients with primary sclerosing cholangitis, with and without inflammatory bowel disease. Aliment Pharmacol Ther 2015; 41:980-90. [PMID: 25783671 PMCID: PMC4402146 DOI: 10.1111/apt.13154] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2014] [Revised: 12/13/2014] [Accepted: 02/14/2015] [Indexed: 02/06/2023]
Abstract
BACKGROUND The relationships between primary sclerosing cholangitis (PSC) and the environment are largely unknown. AIM To validate associations reported in previous studies and to identify novel environmental exposures among PSC patients. METHODS We performed a multicenter, case-control analysis utilising self-administered questionnaires. Responses between cases (n = 1000) and controls (n = 663) were compared using multivariable logistic regression adjusted for age and gender. The model was further stratified based on inflammatory bowel disease (IBD) status (with IBD n = 741 without IBD n = 259). RESULTS Smoking was associated with PSC only when IBD was present (OR, 0.5; 95% CI 0.4-0.7) but not among those PSC patients without IBD (OR, 0.9; 95% CI 0.7-1.2). Compared to controls, women with PSC (irrespective of the presence of IBD) were less likely to have received hormone replacement therapy (HRT; OR, 0.5; 95% CI 0.4-0.7) and were more likely to have recurrent urinary tract infections (OR, 1.6; 95% CI 1.2-2.3). PSC patients regardless of gender or IBD status were less likely to eat fish (OR, 0.4; 95% CI 0.3-0.6) and grilled/barbecued meat (OR, 0.8; 95% CI 0.7-0.9). In contrast, PSC patients with and without IBD were more likely to consume steak/burgers that were more well done (OR, 1.3; 95% CI 1.2-1.5). CONCLUSIONS IBD (rather than PSC) is associated with smoking. Women with PSC are more likely to have recurrent urinary tract infections and less likely to receive HRT. Dietary intake and methods of food preparation differ in PSC patients when compared to controls.

Abstract
The adult primary care "physician shortage" is more accurately portrayed as a gap between the adult population's demand for primary care services and the capacity of primary care, as currently delivered, to meet that demand. Given current trends, producing more adult primary care clinicians will not close the demand-capacity gap. However, primary care capacity can be greatly increased without many more clinicians: by empowering licensed personnel, including registered nurses and pharmacists, to provide more care; by creating standing orders for nonlicensed health personnel, such as medical assistants, to function as panel managers and health coaches to address many preventive and chronic care needs; by increasing the potential for more patient self-care; and by harnessing technology to add capacity.

Abstract
Genital tract carriage of group B streptococcus (GBS) is prevalent among adult women; however, the dynamics of chronic GBS genital tract carriage, including how GBS persists in this immunologically active host niche long term, are not well defined. To our knowledge, in this study, we report the first animal model of chronic GBS genital tract colonization using female mice synchronized into estrus by delivery of 17β-estradiol prior to intravaginal challenge with wild-type GBS 874391. Cervicovaginal swabs, which were used to measure bacterial persistence, showed that GBS colonized the vaginal mucosa of mice at high numbers (10(6)-10(7) CFU/swab) for at least 90 d. Cellular and histological analyses showed that chronic GBS colonization of the murine genital tract caused significant lymphocyte and PMN cell infiltrates, which were localized to the vaginal mucosal surface. Long-term colonization was independent of regular hormone cycling. Immunological analyses of 23 soluble proteins related to chemotaxis and inflammation showed that the host response to GBS in the genital tract comprised markers of innate immune activation including cytokines such as GM-CSF and TNF-α. A nonhemolytic isogenic mutant of GBS 874391, Δcyle9, was impaired for colonization and was associated with amplified local PMN responses. Induction of DNA neutrophil extracellular traps, which was observed in GBS-infected human PMNs in vitro in a hemolysin-dependent manner, appeared to be part of this response. Overall, this study defines key infection dynamics in a novel murine model of chronic GBS genital tract colonization and establishes previously unknown cellular and soluble defense responses to GBS in the female genital tract.

Abstract
BACKGROUND The cause of acute uncomplicated cystitis is determined on the basis of cultures of voided midstream urine, but few data guide the interpretation of such results, especially when gram-positive bacteria grow. METHODS Women from 18 to 49 years of age with symptoms of cystitis provided specimens of midstream urine, after which we collected urine by means of a urethral catheter for culture (catheter urine). We compared microbial species and colony counts in the paired specimens. The primary outcome was a comparison of positive predictive values and negative predictive values of organisms grown in midstream urine, with the presence or absence of the organism in catheter urine used as the reference. RESULTS The analysis of 236 episodes of cystitis in 226 women yielded 202 paired specimens of midstream urine and catheter urine that could be evaluated. Cultures were positive for uropathogens in 142 catheter specimens (70%), 4 of which had more than one uropathogen, and in 157 midstream specimens (78%). The presence of Escherichia coli in midstream urine was highly predictive of bladder bacteriuria even at very low counts, with a positive predictive value of 10(2) colony-forming units (CFU) per milliliter of 93% (Spearman's r=0.944). In contrast, in midstream urine, enterococci (in 10% of cultures) and group B streptococci (in 12% of cultures) were not predictive of bladder bacteriuria at any colony count (Spearman's r=0.322 for enterococci and 0.272 for group B streptococci). Among 41 episodes in which enterococcus, group B streptococci, or both were found in midstream urine, E. coli grew from catheter urine cultures in 61%. CONCLUSIONS Cultures of voided midstream urine in healthy premenopausal women with acute uncomplicated cystitis accurately showed evidence of bladder E. coli but not of enterococci or group B streptococci, which are often isolated with E. coli but appear to rarely cause cystitis by themselves.

Abstract
BACKGROUND Urinary tract infection (UTI) is a common emergency department (ED) complaint and self-diagnosis may be possible. OBJECTIVE The objective was to compare female patient self-diagnosis compared with emergency physician (EP) diagnosis of UTI. METHODS This was a prospective cohort study in a single urban ED. Women aged 18-64 years with a chief complaint of UTI, urinary frequency, or dysuria who presented to an urban academic ED were enrolled in a convenience sample fashion. Patients completed a written four-question survey by an ED greeter before triage. Charts of respondents were reviewed for demographic, laboratory, and EP diagnosis. RESULTS Fifty women were enrolled; 100% of patients who were approached participated in the study. Mean age was 33.7 years (standard deviation 13.8). Forty-three patients (86%) had a history of UTI. Forty-one patients (82%) thought they had a UTI on the index visit. Thirty patients (60%) preferred to buy over-the-counter antibiotics for their symptoms instead of seeing a doctor. Fifteen patients (30%) identified a specific antibiotic they would take. Of the 41 patients who thought they had a UTI, 25 (61%) were given that diagnosis. Of the 30 patients who would have preferred over-the-counter antibiotics, 20 (67%) were actually prescribed them. Agreement between EP and women's final impressions was low (κ = 0.11). CONCLUSIONS There was poor agreement between EP diagnosis and self-diagnosis of UTI. In our ED population, women should be encouraged to seek medical attention to confirm the diagnosis.

Abstract
BACKGROUND Recurrent urinary tract infections (UTIs) are a common problem among women. However, comparative effectiveness strategies for managing recurrent UTIs are lacking. METHODS We performed a systematic literature review of management of women experiencing ≥3 UTIs per year. We then developed a Markov chain Monte Carlo model of recurrent UTI for each management strategy with ≥2 adequate trials published. We simulated a cohort that experienced 3 UTIs/year and a secondary cohort that experienced 8 UTIs/year. Model outcomes were treatment efficacy, patient and payer cost, and health-related quality of life. RESULTS Five strategies had ≥2 clinical trials published: (1) daily antibiotic (nitrofurantoin) prophylaxis; (2) daily estrogen prophylaxis; (3) daily cranberry prophylaxis; (4) acupuncture prophylaxis; and (5) symptomatic self-treatment. In the 3 UTIs/year model, nitrofurantoin prophylaxis was most effective, reducing the UTI rate to 0.4 UTIs/year, and the most expensive to the payer ($821/year). All other strategies resulted in payer cost savings but were less efficacious. Symptomatic self-treatment was the only strategy that resulted in patient cost savings, and was the most favorable strategy in term of cost per quality-adjusted life-year (QALY) gained. CONCLUSIONS Daily antibiotic use is the most effective strategy for recurrent UTI prevention compared to daily cranberry pills, daily estrogen therapy, and acupuncture. Cost savings to payers and patients were seen for most regimens, and improvement in QALYs were seen with all. Our findings provide clinically meaningful data to guide the physician-patient partnership in determining a preferred method of prevention for this common clinical problem.

Abstract
BACKGROUND Emergency physicians often encounter females presenting with symptoms suggestive of urinary tract infections (UTIs). The diagnostic accuracy of history, physical examination, and bedside laboratory tests for female UTIs in emergency departments (EDs) have not been quantitatively described. OBJECTIVES This was a systematic review to determine the utility of history and physical examination (H&P) and urinalysis in diagnosing uncomplicated female UTI in the ED. METHODS The medical literature was searched from January 1965 through October 2012 in PUBMED and EMBASE using the following criteria: Patients were females greater than 18 years of age in the ED suspected of having UTIs. Interventions were H&P and urinalysis used to diagnose a UTI. The comparator was UTI confirmed by a positive urine culture. The outcome was operating characteristics of the interventions in diagnosing a UTI. Study quality was assessed using Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS-2). Sensitivity, specificity, and likelihood ratios (LRs) were calculated using Meta-DiSc. RESULTS Four studies (pooled n = 948) were included with UTI prevalence ranging from 40% to 60%. H&P variables all had positive LRs (+LR, range = 0.8 to 2.2) and negative LRs (-LR, range = 0.7 to 1.0) that are insufficient to significantly alter pretest probability of UTI. Only a positive nitrite reaction (+LR = 7.5 to 24.5) was useful to rule in a UTI. To rule out UTI, only a negative leukocyte esterase (LE; -LR = 0.2) or blood reaction on urine dipstick (-LR = 0.2) were significantly accurate. Increasing pyuria directly correlated with +LR, and moderate pyuria (urine white blood cells [uWBC] > 50 colony-forming units [CFUs]/ml) and moderate bacteruria were good predictors of UTI (+LR = 6.4 and 15.0, respectively). CONCLUSIONS No single H&P finding can accurately rule in or rule out UTI in symptomatic women. Urinalysis with a positive nitrite or moderate pyuria and/or bacteruria are accurate predictors of a UTI. If the pretest probability of UTI is sufficiently low, a negative urinalysis can accurately rule out the diagnosis.

Abstract
BACKGROUND Rheumatoid arthritis is a chronic inflammatory condition that affects the joints causing unpredictable episodes of pain, stiffness and disability. People with rheumatoid arthritis usually require lifelong specialist follow-up but frequently have periods when their disease can be managed through self-care or that provided by their general practitioner. Compared to the traditional clinician-driven care in rheumatoid arthritis, patient-initiated care has proven to be more beneficial in terms of reducing unnecessary medical reviews, providing greater satisfaction to patients and staffs and maintaining the patient's physical and psychological status. We aim to evaluate the implementation of a patient-initiated review system in a routine secondary care rheumatology service in a public hospital in England, where patients get the opportunity to self-manage their disease by requesting specialist reviews at times of need instead of clinician-scheduled appointments. METHODS/DESIGN Three hundred and eighty patients attending routine review at Plymouth Hospitals NHS Trust will be randomised to either enrol immediately into a patient-initiated review system (direct access group), or to be seen regularly by a clinician at the hospital (regular clinician-initiated group). Patients (or their general practitioner) in the direct access group can arrange a review by calling a rheumatology nurse-led advice line that enables telephone delivered clinical advice, or where appropriate, an appointment with a rheumatologist within 10 working days. Patients in the regular clinician-initiated group will attend their planned appointments at regular intervals during the intervening period of 12 months. The primary outcome of interest is patient satisfaction; secondary outcomes include service use, waiting times and clinical measures. Semi-structured, in-depth interviews will be conducted with a subset of patients and staff with the aim of identifying facilitators/barriers in implementing patient-initiated clinics. DISCUSSION The implementation of a patient-initiated review system in routine care rheumatology will replace the fixed clinician-driven review system with a more flexible patient-driven system where patients usually self-manage their disease, but can request prompt help when required. We believe that this study will enable a comparison of the changes in local services and will be helpful in exploring the benefits/drawbacks of such implementation, thus providing lessons for implementation in other hospitals and for other chronic diseases.

Abstract
This study evaluated patient-initiated single-dose antibiotic prophylaxis and continuous long-term low-dose daily antibiotic use for the prevention of recurrent urinary tract infections (UTI) in 68 postmenopausal women. The women were randomized to take a low-dose antibiotic each night (continuous group, n = 37) or a single-dose antibiotic each time they experienced conditions predisposing to UTI (intermittent group, n = 31). During the 12-month study, 1.4 and 1.9 UTIs/patient developed in the continuous and the intermittent groups, respectively, which was significantly lower than the incidence of UTIs in the previous 12 months in these patients (4.7 and 5.1 UTIs/patient, respectively). The incidence of gastro intestinal adverse events was significantly lower in the intermittent group compared with the continuous group (9.1% versus 30.0%). In conclusion, patient-initiated single-dose intermittent antibiotic prophylaxis was as effective as low-dose daily antibiotic prophylaxis in the treatment of recurrent UTIs in post menopausal women and was associated with fewer gastrointestinal adverse events.

Abstract
BACKGROUND Current clinical guidelines for the management of symptoms suggesting urinary tract infection recommend empiric antibiotic therapy. OBJECTIVE To determine the diagnostic accuracy of urinary tract symptoms for early identification of urinary tract infection (UTI) in sexually active women when culture results are not available. METHOD This was a cross-sectional observational study conducted in a tertiary care hospital between July 2009 and May 2011. Subjects comprised 312 women ≥ 18 year of age who reported to the physician with symptoms suggestive of UTI. A predesigned questionnaire was filled and urine was analysed by microscopic examination and culture. Diagnostic values were calculated against gold standard urine culture results (> 10(2) CFU/ml) and 95% CIs and likelihood ratios are reported. RESULTS A total of 312 women were enrolled, as culture was contaminated in 36 only 276 women were included in final analysis. Prevalence of UTI was 46.01% amongst symptomatic women. Urgency (p = 0.001), burning sensation during micturition (p = 0.035), dysuria (p = 0.004), frequency of sexual intercourse > 5 per month (p = 0.010) and pyuria (p = 0.000) were significantly associated with culture positivity. Absence of pyuria emerged as best predictor for ruling out UTI even if the woman had symptoms (sensitivity 93.70%, NPV 91.84%, AUC 77.07%, LR- 0.1). The combination of urgency, burning during micturition and pyuria was the best predictor of UTI in our study (sensitivity 85.83%, PPV 71.71%, AUC 78.48%, LR+ 2.97) CONCLUSION Symptoms alone have low accuracy when assessed against the reference standard for diagnosing UTI. Empiric treatment of UTI based on symptoms may expose large number of patients to unnecessary antibiotics. Wet mount microscopy for presence of pyuria as a 'near patient test' before starting antibiotics seems a rational approach for management of UTI in symptomatic women.

Abstract
OBJECTIVE To compare the time to urinary tract infection (UTI) and the rates of asymptomatic bacteriuria and urinary P-fimbriated Escherichia coli during a 6-month period in women ingesting cranberry vs placebo juice daily. PATIENTS AND METHODS Premenopausal women with a history of recent UTI were enrolled from November 16, 2005, through December 31, 2008, at 2 centers and randomized to 1 of 3 arms: 4 oz of cranberry juice daily, 8 oz of cranberry juice daily, or placebo juice. Time to UTI (symptoms plus pyuria) was the main outcome. Asymptomatic bacteriuria, adherence, and adverse effects were assessed at monthly visits. RESULTS A total of 176 participants were randomized (120 to cranberry juice and 56 to placebo) and followed up for a median of 168 days. The cumulative rate of UTI was 0.29 in the cranberry juice group and 0.37 in the placebo group (P=.82). The adjusted hazard ratio for UTI in the cranberry juice group vs the placebo group was 0.68 (95% confidence interval, 0.33-1.39; P=.29). The proportion of women with P-fimbriated urinary E coli isolates during the intervention phase was 10 of 23 (43.5%) in the cranberry juice group and 8 of 10 (80.0%) in the placebo group (P=.07). The mean dose adherence was 91.8% and 90.3% in the cranberry juice group vs the placebo group. Minor adverse effects were reported by 24.2% of those in the cranberry juice group and 12.5% in the placebo group (P=.07). CONCLUSION Cranberry juice did not significantly reduce UTI risk compared with placebo. The potential protective effect we observed is consistent with previous studies and warrants confirmation in larger, well-powered studies of women with recurrent UTI. The concurrent reduction in urinary P-fimbriated E coli strains supports the biological plausibility of cranberry activity. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00128128.

Abstract
Recurrent urinary tract infections most often present with symptoms of irritative voiding. In most cases, they are caused by reinfection with a previously isolated organism. Patients with one or more symptoms of uncomplicated recurrent urinary tract infection should undergo thorough examination and screening for underlying comorbidities that increase susceptibility. When frequent reinfections, empiric treatment relapse, persistent infections, or risk factors for complicated infections are encountered, patients may benefit from urodynamics, cystoscopy, renal ultrasound, intravenous urogram, or voiding cystourethrogram to evaluate for anatomic, functional, or metabolic abnormalities affecting the urinary tract (e.g., stones, stricture, obstruction, vesicoureteral reflux, lesions, detrusor underactivity). These patients may benefit from culture-guided empiric treatment and further evaluation by urology, nephrology, or infectious disease specialists. In patients with a history of uncomplicated urinary tract infections, empiric treatment guided by local antimicrobial resistance may efficiently treat a suspected recurrence. After successful treatment of the acute infection, postcoital prophylaxis, continuous prophylaxis, or self-start empiric treatment may be selected based on frequency of recurrent infections, temporal relation to intercourse, and patient characteristics. Ancillary measures such as probiotics, cranberry products, or local estrogen replacement may also be considered. This article will review the current definition, epidemiology, pathogenesis, diagnosis, work-up, treatment, treatment side effects, and prevention of recurrent urinary tract infections in women. A suggested algorithm for evaluation and treatment based on current literature is provided.

Abstract
Recurrent urinary tract infections (UTIs) in women are common, result in considerable morbidity and expense, and can be a management problem for clinicians. Behavioural changes can be useful antimicrobial-sparing measures in the prevention of recurrent UTIs, but antimicrobial prophylaxis may be necessary in those who continue to have recurrences. Continuous prophylaxis, post-coital prophylaxis and intermittent self-treatment with antimicrobials have all been demonstrated to be effective in the prevention of recurrent uncomplicated UTIs. The decision as to which approach to use depends upon the frequency and pattern of recurrences and willingness of the patient to commit to a specific regimen. The risk of adverse events, including antimicrobial resistance, patient's lifestyle and compliance and plans for a pregnancy also need to be considered. The choice of antimicrobial should be based upon the susceptibility pattern of the organisms causing the patient's previous UTIs and history of drug allergies.

Abstract
Antimicrobial prophylaxis is commonly used by clinicians for the prevention of numerous infectious diseases, including herpes simplex infection, rheumatic fever, recurrent cellulitis, meningococcal disease, recurrent uncomplicated urinary tract infections in women, spontaneous bacterial peritonitis in patients with cirrhosis, influenza, infective endocarditis, pertussis, and acute necrotizing pancreatitis, as well as infections associated with open fractures, recent prosthetic joint placement, and bite wounds. Perioperative antimicrobial prophylaxis is recommended for various surgical procedures to prevent surgical site infections. Optimal antimicrobial agents for prophylaxis should be bactericidal, nontoxic, inexpensive, and active against the typical pathogens that can cause surgical site infection postoperatively. To maximize its effectiveness, intravenous perioperative prophylaxis should be administered within 30 to 60 minutes before the surgical incision. Antimicrobial prophylaxis should be of short duration to decrease toxicity and antimicrobial resistance and to reduce cost.

Abstract
AIM To explore the knowledge, and health beliefs of patients with type 2 diabetes mellitus (T2DM) regarding management of infections of the urinary tract (UTIs) and lower respiratory tract (LRTIs). METHODS Three semi-structured focus groups with 23 patients with T2DM were conducted and analyzed. RESULTS Only a few patients mentioned specific preventive measures for UTIs and LRTIs, like not smoking and taking enough fluids (n=3). Making a nuisance of oneself, denying the seriousness of the disease and fear of insulin therapy were barriers to health-seeking behaviour. Some people did not complete the course of antibiotics (n=2) or forgot to take the tablets, especially when tablets had to be taken more than once a day (n=4). CONCLUSION Our results showed that patients with T2DM lack knowledge and realistic health beliefs about common infections such as UTIs and LRTIs. Health education should aim to help patients with T2DM to interpret symptoms of infections correctly in order to take the appropriate action such as taking preventive measures or taking antibiotics. Identifying patients at high risk of a complicated infection may target education towards those who need it most.

Abstract
OBJECTIVE to provide an update of the definition, epidemiology, clinical presentation, investigation, treatment, and prevention of recurrent urinary tract infections in women. OPTIONS continuous antibiotic prophylaxis, post-coital antibiotic prophylaxis, and acute self-treatment are all efficient alternatives to prevent recurrent urinary tract infection. Vaginal estrogen and cranberry juice can also be effective prophylaxis alternatives. EVIDENCE a search of PubMed and The Cochrane Library for articles published in English identified the most relevant literature. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date restrictions. VALUES this update is the consensus of the Sub-Committee on Urogynaecology of the Society of Obstetricians and Gynaecologists of Canada. Recommendations were made according to the guidelines developed by the Canadian Task Force on Preventive Health Care (Table 1). OPTIONS recurrent urinary tract infections need careful investigation and can be efficiently treated and prevented. Different prophylaxis options can be selected according to each patient's characteristics.

Abstract
BACKGROUND Self-diagnosis of influenza is an important component of pandemic control and management as it may support self-management practices and reduce visits to healthcare facilities, thus helping contain viral spread. However, little is known about the accuracy of self-diagnosis of influenza, particularly during pandemics. METHODS We used cross-sectional survey data to correlate self-diagnosis of influenza with serological evidence of 2009 pandemic influenza A(H1N1) infection (haemagglutination inhibition titres of ≥1:40) and to determine what symptoms were more likely to be present in accurate self-diagnosis. The sera and risk factor data were collected for the national A(H1N1) seroprevalence survey from November 2009 to March 2010, 3 months after the first pandemic wave in New Zealand (NZ). RESULTS The samples consisted of 318 children, 413 adults and 423 healthcare workers. The likelihood of being seropositive was no different in those who believed they had influenza from those who believed they did not have influenza in all groups. Among adults, 23.3% (95% CI 11.9% to 34.7%) of those who reported having had influenza were seropositive for H1N1, but among those reporting no influenza, 21.3% (95% CI 13% to 29.7%) were also seropositive. Those meeting NZ surveillance or Ministry of Health influenza case definitions were more likely to believe they had the flu (surveillance data adult sample OR 27.1, 95% CI 13.6 to 53.6), but these symptom profiles were not associated with a higher likelihood of H1N1 seropositivity (surveillance data adult sample OR 0.93, 95% CI 0.5 to 1.7). CONCLUSIONS Self-diagnosis does not accurately predict influenza seropositivity. The symptoms promoted by many public health campaigns are linked with self-diagnosis of influenza but not with seropositivity. These findings raise challenges for public health initiatives that depend on accurate self-diagnosis by members of the public and appropriate self-management action.

Abstract
Uncomplicated urinary tract infections (UUTI) in women are frequent reasons for consultations in general practice. We evaluated the effectiveness and safety of telemedical management at a telemedicine centre in Switzerland. Management followed evidence-based protocols, including teleprescription of an antibiotic. Consecutive UUTI patients who had a teleconsultation including the prescription of an antibiotic were followed up three days later about symptom relief, adverse events or the need to visit a doctor. Of a total of 526 eligible women, follow-up information was available for 95%. Three days after teleconsultation, 79% of patients reported complete symptom relief, and 92% reported a reduction of UUTI symptoms. Five percent of patients reported deterioration, e.g. due to an increase of pain, flank pain or fever. Four percent reported side-effects of the prescribed antibiotics. In the three days following teleconsultation, 4% of women consulted another health-care provider without further contacting the telemedicine centre. Another 8% of patients were referred to face-to-face consultation because they developed additional symptoms or because bacterial resistance of the prescribed antibiotic was suspected. Compared to data from the literature on UUTI, evidence-based telemedical management including teleprescription of an antibiotic is as safe and effective as prescriptions initiated by a face-to-face consultation.

Abstract
BACKGROUND Women with diabetes have an increased risk of urinary tract infections (UTIs), especially recurrences. Aim. To investigate diabetes characteristics associated with the risk of recurrent lower UTIs and the antibiotic prescription pattern. METHODS In an exploratory retrospective study involving 7063 women aged>or=30 years, we studied the incidence of recurrent UTI (relapses and reinfection) in women with (n=340) and without diabetes (n=6618). Multivariable logistic regression and multilevel multinomial logistic analyses were used to determine the adjusted associations between diabetes characteristics and recurrent UTI [odds ratio (OR); 95% confidence interval (CI)] and the influence of diabetes on the pattern of antibiotic prescriptions for UTI, respectively. RESULTS Relapses and reinfections were reported in 7.1% and 15.9% of women with diabetes versus 2.0% and 4.1% of women without diabetes. There was an independent higher risk of recurrent UTI in women with diabetes compared with women without diabetes (OR 2.0; 95% CI 1.4-2.9). Women taking oral blood glucose-lowering medication (OR 2.1; 95% CI 1.2-3.5) or insulin (OR 3.0; 95% CI 1.7-5.1) or who had had diabetes for >or=5 years (OR 2.9; 95% CI 1.9-4.4) or who had retinopathy (OR 4.1; 95% CI 1.9-9.1) were at risk of recurrent UTI. The pattern of antibiotic prescriptions for UTI was not influenced by diabetes. CONCLUSIONS Women with diabetes>or=5 years or with glucose-lowering medication or with retinopathy have an increased risk of recurrent UTI. Diabetes itself does not seem to influence the antibiotic prescription pattern. Research focusing on effective antibiotic treatment of UTI in women at risk of recurrence is needed and may help limit the development of antibiotic resistance.

Abstract
PURPOSE We determined if the deliberate establishment of asymptomatic bacteriuria with Escherichia coli 83972 in patients with incomplete bladder emptying and recurrent urinary tract infection protects against recurrence. MATERIALS AND METHODS In phase 1 of the study the patients were randomized to blinded inoculations with E. coli 83972 or saline. Crossover occurred after monitoring for 12 months or after a urinary tract infection. The outcome was the time to the first urinary tract infection in patients with and without E. coli 83972 bacteriuria. In phase 2 patients were subjected to additional blinded inoculations to extend periods with and without E. coli 83972 bacteriuria. The outcome was the number of urinary tract infections during 12 months with and 12 months without E. coli 83972 bacteriuria. RESULTS A total of 20 patients completed the study. In phase 1 the time to the first urinary tract infection was longer with than without E. coli 83972 bacteriuria (median 11.3 vs 5.7 months, sign test p = 0.0129). Phase 2 was analyzed after patients had spent a total of 202 months with and 168 months without E. coli 83972 bacteriuria. There were fewer reported urinary tract infection episodes with vs without E. coli 83972 bacteriuria (13 vs 35 episodes, paired t test p = 0.009, CI 0.31-1.89). There was no febrile urinary tract infection episode in either of the study arms and no significant side effects of intravesical bacterial inoculation were reported. CONCLUSIONS Deliberately induced E. coli 83972 bacteriuria protected patients with incomplete bladder emptying who are prone to urinary tract infection from recurrent urinary tract infection as demonstrated by the delay in time to urinary tract infection and the decrease in number of urinary tract infection episodes.

Abstract
SUMMARYWe aimed to develop a prediction rule for urinary tract infections (UTIs) in patients with type 2 diabetes mellitus (DM2). A 12-month prospective cohort study was conducted in patients with DM2 aged ⩾45 years to predict the occurrence of recurrent UTIs in women and lower UTIs in men. Predictors for recurrent UTI in women (n=81, 2%) and lower UTIs in men (n=93, 3%) were age, number of general practitioner (GP) visits, urinary incontinence, cerebrovascular disease or dementia. In women, renal disease was an additional predictor. The optimum corrected area under the receiver-operating curve (AUC) was 0·79 (95% CI 0·74–0·83) for women and 0·75 (95% CI 0·70–0·80) for men. Using a cut-off score of 4, women with a lower risk assignment had a probability of 0·3% for the outcome. For a cut-off score of 6, women with a higher risk assignment had a probability of 5·8%. For men these figures were 0·8 and 7·1 for a cut-off score of 2 and 4, respectively. Simple variables can be used for the risk stratification of patients.

Abstract
The diagnosis and management of adolescent urinary tract infection (UTI) share some of the clinical features seen in infections of the young and old. Whereas most infections in the young patient demand an extensive radiologic work-up, the teenager with a UTI is not so straightforward. The clinician must balance being too aggressive with being too conservative in the diagnosis and management of these patients. UTIs occur most frequently among adolescent females and are usually uncomplicated and not associated with underlying anatomic abnormalities. Smaller numbers of adolescent males suffer from UTIs, and the need to search for underlying abnormalities is not clear. Adolescent UTI is associated with nascent sexual activity and is also more common in voiding/elimination syndromes. Future studies examining UTI, specifically in the adolescent age group, will help provide clinicians with a more focused algorithm in the diagnosis and management of adolescent UTIs.

Abstract
In North America and the United Kingdom, we are in the age of self-management. Many patients with chronic diseases are ready to participate in the therapeutic decision-making process, and join their physicians in a co-management model. It is particularly useful to consider this concept at a time when physician shortages and waiting times are on the front page every day, with no immediate prospect of relief. Conditions such as diabetes, asthma, chronic obstructive pulmonary disease, recurrent urinary tract infections and others lend themselves to this paradigm of medical care for the informed patient. The present paper reviews some of the literature on self-management for the patient with inflammatory bowel disease (IBD), and provides a framework for the use of self-management in the IBD population, with emphasis on the concept of a patient passport, and the use of e-mail, supported by an e-mail contract, as proposed by the Canadian Medical Protective Association. Examples of specific management strategies are provided for several different IBD scenarios. Eliminating the need for some office visits has clear environmental and economical benefits. Potential negative consequences of this form of patient care are also discussed.

Abstract
OBJECTIVE The aim of this study was to assess the short-term effects of an educational program on (determinants of) self-reported health-seeking behavior for infections of the urinary tract (UTIs) and lower respiratory tract (LRTIs) in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS In a randomized controlled trial, 1,124 patients with type 2 diabetes aged between 44 and 85 years participated. The intervention consisted of a multifaceted educational program with an interactive meeting, a leaflet, a Web site, and a consultation with the diabetes care provider. The program focused on the needs of patients, apparent from a prior focus group and questionnaire study. The primary outcome measure was an indicator of health-seeking behavior for UTIs and LRTIs, defined as the proportion of participants with a positive score on at least seven of nine determinants, six from the Health Belief Model and the additional three domains of knowledge, need for information, and intention. The primary outcome was measured with questionnaires at baseline and after 5 months. RESULTS Complete outcome data were available for 468 intervention group patients and 472 control group patients. In all, 68% of the intervention group patients attended the meeting. At baseline, 28% of the participants from the intervention group had a positive score on seven of the nine determinants, compared with 27% from the control group. After the educational program, these percentages were 53 and 32%, respectively (P < 0.001). CONCLUSIONS Our educational program positively influenced determinants of health-seeking behavior for common infections in patients with type 2 diabetes.

Abstract
PURPOSE Devices used for home evaluation of fertility, pregnancy, menopause, colon cancer, breast cancer, and urinary-tract and vaginal yeast infections are discussed. SUMMARY Ovulation-prediction devices monitor natural changes in a woman's body during the menstrual cycle, including changes in basal body temperature, urinary luteinizing hormone, and urinary estrone-3-glucuronide concentrations. Also available are devices that identify changes in the content of sodium chloride and other electrolytes in saliva and cervical-vaginal mucus. Home pregnancy tests are designed to detect human chorionic gonadotropin in the urine. Both urine and saliva tests are available for home evaluation of menopause; the most common devices use urine to measure follicle-stimulating hormone. The saliva tests measure estradiol, progesterone, and testosterone. Devices for home screening for colon cancer use either the guaiac test or the fecal immunochemical test. For aid in breast self-examination, patients may use a simulated-breast product designed to train them to detect lumps or a thin, silicone-containing pad intended to increase the sensitivity of the fingers to abnormalities. Urine-dipstick tests can be used to screen for urinary-tract infection, and a swab or panty liner can be used to detect vaginal pH changes indicative of vaginal yeast infection. Home-based tests may be convenient and economical but also have limitations; pharmacists can help educate patients and clinicians. CONCLUSION Many devices are available to help evaluate women's health concerns at home.

Abstract
Interstitial cystitis/painful bladder syndrome (IC/PBS) is characterized by urinary frequency, urgency, and pelvic pain in the absence of any other identifiable pathology. Initial identification of IC/PBS is challenging, as patients may have a range of symptoms that overlap with other disorders, including urinary tract infection (UTI). These patients may be treated empirically with antibiotics; however, many patients with such symptoms are actually culture negative and are later diagnosed with IC/PBS. This review describes the importance of recognizing the symptom overlap between IC/PBS and UTI and focuses on approaches to the diagnosis and management of IC/PBS. Physicians can improve patient care by considering IC/PBS early in the differential diagnosis.
