background while tuberculosis (tb) can be diagnosed by microscopy and culture, the sensitivity of ziehl-neelsen staining is variable and culture results require 4 - 8 weeks to be determined. polymerase chain reaction (pcr) and its modifications, including nested pcr, might be promising methods for the rapid diagnosis of tb. objectives this study aimed to evaluate the performance of nested pcr o...

is started on a new antibiotic, always take an “antibiotic timeout” and reassess the patient after the first 48 to 72 hours of antimicrobial therapy to assure that the patient has responded to the antimicrobial therapy, as many of the uropathogens are multidrug-resistant. A urinalysis and culture should be collected based on the patient’s symptoms and not solely based on the urine’s characteris...

A simple, inexpensive, non-invasive method for urine collection was used in 28 consecutive infants for periods of 48 hours (n = 10) and 72 hours (n = 18). The incidence of urine collector detachment was low on the first and second days (< 4%) and increased significantly on the third day (28%). Volume of urine leaked was < 4% of the total volume collected daily. This method is applicable to both...

This chapter reports on a field trial involving the application of hair assays to a probation population. The objectives were to evaluate the general reactions of probation officers and probationers to the collection of hair samples, to compare the outcomes of the hair samples with the outcomes of urinalyses (which the probationers undergo routinely), to note and react to differences in the pre...

The usefulness of preparatory vulval cleansing before urine specimen collection was evaluated in women aged 16 to 75 years attending a general practice. A total of 316 specimens were examined, 158 from women with symptoms of cystitis and 158 from controls. No significant differences were found in the numbers of contaminated or unreliable results between the specimens collected with and those co...

Twenty-eight active international athletes agreed to be available for random spot urine collections at their homes, places of work and training. Suitable briefed collectors were arranged to conduct the spot collections and forward the specimens for analysis. An average number of 3.4 collections per athlete was made in the 9 month period of the trial. Overall there was a "failure to collect" per...

Method: 36 male 9-10 years children were invited to participate in this study, and 30 completed a 24 h urine collection. The Free Water Reserve (FWR) was used to assess the hydration status; additionally, a food record corresponding to the day of urine collection and a lifestyle, and socio-demographic questionnaire was filled with parents help. Anthropometric data were obtained. Food and bevera...

BACKGROUND Urinalysis testing is frequently ordered in the emergency department (ED), but contamination of urine specimens limits the interpretation of results. The mid-stream, clean-catch (MSCC) procedure for urine specimen collection is recommended to decrease contamination rates, but without instructions this procedure has poor compliance. OBJECTIVE To evaluate the effectiveness of written...

INTRODUCTION Children have an increased risk of voluntary dehydration especially during physical activity which may increase the risk of non-compensating water losses. OBJECTIVES The aim of this study was to assess the hydration status and its relation to food intake in a children group of soccer players. METHOD A sample of 36 boys aged 9-10 years was included in this study; 30 completed a ...
