BACKGROUND Urinary tract infection (UTI) in childhood can be diagnosed in 5% of febrile infants. Renal scarring is associated with increasing numbers of UTI episodes, and the incidence of renal scarring rises with each urinary infection. High levels of awareness of childhood UTI are important among both professionals and parents. Whilst problems for professionals in making the diagnosis have be...

This is the case of a 38 year-old female patient with an intrauterine pregnancy, in which a previous incidentally identified adrenal mass proved to be a pheochromocytoma during the antenatal period. The patient was started on α-and β-adrenergic blockade to maintain hemodynamic stability, and surgical removal of the lesion was performed during the second trimester without major complications. In...

Animals and materials Healthy male rabbits of about 2. 5kg body weight were kept in individual cages under a carefully controlled condition and their whole urines were collected daily to extract crude uroparotin according to the procedure previously described(Ito and Yamamoto, 1958). The extirpation of the salivary gland After the normal urine of each rabbit was collected as an intact control f...

A rapid technique suitable for routine pathology laboratories has been used to estimate methylmalonic acid excretion in a 24-hour urine collection following a 10g. valine load. Levels above 40 mg./24 hours were found only in patients with vitamin B(12) deficiency. Patients with pernicious anaemia treated more than 24 hours before urine collection and patients with other types of anaemia had met...

This procedure would have two advantages. The first is that it would overcome many of the administrative difficulties, both on the ward and in the laboratory, which arise from the necessity of sending a plasma sample and request card to the laboratory on one day and the 24-hour urine sample with a second request card on the following day. If the plasma is taken when the collection is completed,...

BACKGROUND Urinary tract infections (UTIs) in childhood are common and may be difficult to diagnose because of non-specific symptoms and technical problems with urine collection. Active management is important because UTIs may cause permanent renal scarring in young children. AIM To determine how general practitioners (GPs) manage children with suspected UTIs. METHOD A postal questionnaire ...

BACKGROUND The protein:creatinine ratio in random, untimed urine samples correlates with 24-h protein excretion in pregnant women with and without hypertension. Nevertheless, whether this ratio is appropriate as a screening test for proteinuria is still unclear, in part because of the paucity of large studies. METHODS We measured protein:creatinine ratios in random urine samples and protein c...

OBJECTIVE To update the estimate of mean salt intake for the Australian population made by the Australian Health Survey (AHS). DESIGN A secondary analysis of the data collected in a cross-sectional survey was conducted. Estimates of salt intake were made in Lithgow using the 24 h diet recall methodology employed by the AHS as well as using 24 h urine collections. The data from the Lithgow sam...

Analysis for calcium, magnesium, phosphorus, oxalate, uric acid, and creatinine in 24-h urine collections is often needed for the differential diagnosis of patients with renal calculi. Considerable attention has been given to improving the methods of analysis, but improper sample collection and processing can cause significant errors for calcium and oxalate in urine samples not treated with aci...

BACKGROUND The average dietary sodium intake of Koreans is 2.6 times higher than the World Health Organization's recommended amount. The effect of a diet high in sodium on the skeletal system, especially osteoporosis, has not previously been examined in Korean postmenopausal women with low bone mass. We assessed the daily sodium intake, and determined the impact of sodium intake on urinary calc...
