Urine Testing (urine + testing)
Selected AbstractsAssessing diabetic control , reliability of methods available in resource poor settingsDIABETIC MEDICINE, Issue 3 2002A. P. Rotchford Abstract Aims and methods To examine the reliability of random venous or capillary blood glucose testing, random urine glucose testing, and a current symptom history in predicting a high HbA1c in Type 2 diabetic patients taking oral hypoglycaemic agents in a poorly controlled rural African population. Results For a cut-off point for HbA1c of , 8%, for random venous plasma glucose of , 14 mmol/L (present in 47.2% of subjects), specificity was 97.1% (95% CI 85.1,99.9), sensitivity 56.8% (48.8,64.5) and positive predictive value (PPV) 98.9% (94.2,99.9). HbA1c, 8% is predicted by a random capillary blood glucose of 17 mmol/L (present in 28.4% of subjects) with specificity 100% (90.0,100.0), PPV 100% (93.7,100.0) and sensitivity of 34.3% (27.2,42.1). HbA1c, 8% is predicted by the presence of heavy glycosuria (, 55 mmol/L) (present in 35.6%) with specificity 94.1% (80.3,99.3), sensitivity of 41.9% (34.1,49.9) and PPV 97.1% (89.9,99.6). Polyuria/nocturia (present in 31.3%) was the only symptom found to be associated with poor control, with a specificity for predicting HbA1c of , 8% of 81.5% (61.9,93.7), PPV 89.1% (76.4,96.4) and sensitivity 30.6% (22.9,39.1). Conclusions Where resources are short, random glucose testing can be used to detect a significant proportion of those with the worst control with a high degree of specificity enabling primary care staff to modify treatment safely. Where facilities are limited capillary blood or urine testing with reagent strips, may be substituted for venous plasma testing in the laboratory. A symptom history was insufficient to replace biochemical testing, but where this is unavailable, urinary symptoms may be helpful. Diabet. Med. 19, 195,200 (2002) [source] The Global Diversion of Pharmaceutical DrugsADDICTION, Issue 9 2010Opiate treatment, the diversion of pharmaceutical opiates: a clinician's perspective ABSTRACT Aim To provide a clinician's perspective on the problem of diversion of prescribed pharmaceuticals. Methods The paper provides a personal account of working in a treatment context where diversion from opioid substitution treatment (OST) became a political issue potentially compromising the continued delivery of OST. It summarizes evidence on the impact of diversion, and measures to contain it, from the United Kingdom 1986,2006, Australia 1996,2008 and the United States and France from the mid-1990s. Results Opioid diversion to the black market occurs in proportion to the amount of opioids prescribed to be taken without supervision, and in inverse proportion to the availability of heroin. Diversion for OST programmes using supervision of dosing is less than diversion of opioids prescribed for pain, which is now a growing public health problem. Adverse consequences of diversion include opioid overdose fatalities, an increased incidence of addiction (particularly in jurisdictions where heroin is scarce) and compromising the public acceptance of long-term opioid prescribing. All long-term opioid prescribing requires monitoring of risk and appropriate dispensing arrangements,including dilution of methadone take-aways, supervision of administration for high-risk patients and random urine testing. Clinical guidelines influence practice, although prescribing often deviates from guidelines. Conclusion Clinical guidelines and clinical audit to enhance compliance with guidelines are helpful in maintaining the quality and integrity of the treatment system, and can contribute to keeping diversion within acceptable levels. [source] Opportunistic screening for Chlamydia in general practice: the experience of health professionalsHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 4 2003Elizabeth Perkins Abstract Chlamydia trachomatis is the most common curable bacterial sexually transmitted infection in the UK. The infection is asymptomatic in up to 70% of women, and if untreated, can lead to pelvic inflammatory disease, ectopic pregnancy and infertility. Chlamydial infection can be diagnosed using urine testing and is easily treated with antibiotics. In 1999, the UK Department of Health funded a pilot opportunistic Chlamydia screening programme in two health authorities. All sexually active women between the ages of 16 and 24 years attending general practices and other healthcare settings, such as family planning clinics, antenatal clinics and genito-urinary medicine services, were offered the opportunity to be screened for Chlamydia, regardless of the purpose of their visit. This evaluation was funded to assess the feasibility and acceptability of opportunistic screening. The evaluation was conducted using both qualitative and quantitative methods. The present paper describes findings from the qualitative evaluation study arising from the health professionals' experience of opportunistic screening in general practice. Receptionists were central to the opportunistic screening model in general practice and it was this aspect of the model that raised most concerns. Whilst general practitioners reported that the involvement of receptionists saved them time, the receptionists themselves were sometimes drawn into discussions for which they felt ill equipped and unsuitably located. This research suggests that a call,recall national screening programme would provide a better model to undertake Chlamydia screening in general practice. The advantages of this model are threefold. First, each individual within the target age range can receive information about Chlamydia through the post. Secondly, the test and more detailed information can be managed by a practice nurse in a private and confidential setting. Thirdly, individuals are not repeatedly offered the test when visiting the surgery. [source] Serious Bacterial Infection in Recently Immunized Young Febrile InfantsACADEMIC EMERGENCY MEDICINE, Issue 12 2009Margaret Wolff MD Abstract Objective:, The objective of this study was to investigate the prevalence of serious bacterial infection (SBI) in febrile infants without a source aged 6,12 weeks who have received immunizations in the preceding 72 hours. Methods:, The authors conducted a medical record review of infants aged 6,12 weeks with a fever of ,38.0°C presenting to the pediatric emergency department (ED) over 88 months. Infants were classified either as having received immunizations within the 72 hours preceding the ED visit (recent immunization [RI]) or as not having received immunizations during this time period (no recent immunization [NRI]). Primary outcome of an SBI was based on culture results; only patients with a minimum of blood and urine cultures were studied. Results:, A total of 1,978 febrile infants were studied, of whom 213 (10.8%) had received RIs. The overall prevalence of definite SBI was 6.6% (95% confidence interval [CI] = 5.5 to 7.7). The prevalence of definite SBI in NRI infants was 7.0% (95% CI = 5.9 to 8.3) compared to 2.8% (95% CI = 0.6 to 5.1) in the RI infants. The prevalence of definite SBI in febrile infants vaccinated in the preceding 24 hours decreased to 0.6% (95% CI = 0 to 1.9). The prevalence of definite SBI in febrile infants vaccinated greater than 24 hours prior to presentation was 8.9% (95 CI = 1.5 to 16.4). The relative risk of SBI with RI was 0.41 (95% CI = 0.19 to 0.90). All SBIs in the RI infants were urinary tract infections (UTI). Conclusions:, Among febrile infants, the prevalence of SBI is less in the initial 24 hours following immunizations. However, there is still a substantial risk of UTI. Therefore, urine testing should be considered in febrile infants who present within 24 hours of immunization. Infants who present greater than 24 hours after immunizations with fever should be managed similarly to infants without RIs. [source] Type 2 diabetes in adolescence , unearthed at the time of registration with the general practitioner (GP)PRACTICAL DIABETES INTERNATIONAL (INCORPORATING CARDIABETES), Issue 8 2000GYT Ng Abstract Type 2 diabetes, or non-insulin-dependent diabetes mellitus (NIDDM), is often considered to be a diagnosis of adulthood. We present a 13 year old boy who was noted to have glycosuria on routine general practitioner (GP) urine testing. Clinical examination upon referral showed massive obesity, hypertension and prominent acanthosis nigricans, and investigations confirmed hyperinsulinaemia and hyperglycaemia. Metformin and a programme of weight reduction comprise the management of this young adolescent with type 2 diabetes. Such early diagnosis should permit the institution of appropriate management to avoid the early emergence of the complications of type 2 diabetes. Copyright © 2000 John Wiley & Sons, Ltd. [source] Diagnostic performance of urine dipstick testing in children with suspected UTI: a systematic review of relationship with age and comparison with microscopyACTA PAEDIATRICA, Issue 4 2010R Mori Abstract Background:, Prompt diagnosis of urinary tract infection (UTI) in children is needed to initiate treatment but is difficult to establish without urine testing, and reliance on culture leads to delay. Urine dipsticks are often used as an alternative to microscopy, although the diagnostic performance of dipsticks at different ages has not been established systematically. Method:, Studies comparing urine dipstick testing in infants versus older children and urine dipstick versus microscopy were systematically searched and reviewed. Meta-analysis of available studies was conducted. Results:, Six studies addressed these questions. The results of meta-analysis showed that the performance of urine dipstick testing was significantly less in the younger children when compared with older children (p < 0.01). Positive likelihood ratio (LR) of both nitrite and leucocyte positive 38.54 [95% confidence interval (CI) 22.49,65.31], negative LR for both negative 0.13 (95% CI 0.07,0.25) are reasonably good, and those for young infants are less reliable [positive LR 7.62 (95% CI 0.95,51.85) and negative LR 0.34 (95% CI 0.66,0.15)]. Comparing microscopy and urine dipstick testing, using bacterial colony count on urine culture showed no significant difference between the two methods. Conclusion:, Urine dipstick testing is more effective for diagnosis of UTI in children over 2 years than for younger children. [source] |
