This study determine effectiveness prepared three teaching modules, namely negotiating text module for SMA Negeri 4 Palembang, 2 Ungaran, 1 ...

BACKGROUND Acute urinary tract infections (UTI) are one of the most common bacterial infections among women presenting to primary care. However, there is a lack of consensus regarding the optimal reference standard threshold for diagnosing UTI. The objective of this systematic review is to determine the diagnostic accuracy of symptoms and signs in women presenting with suspected UTI, across thr...

Many clinics are now reporting a fresh increase in the number of patients (mainly males) with infectious syphilis. The rheumatism clinics may be the first to see those cases in which syphilitic disease has attacked the bones or joints of small infants, older children, teenagers, and adults. Because early infectious syphilis was extremely prevalent during and immediately after the second world w...

A common challenge in diagnostic studies is to obtain a correct final diagnosis in all participants. Ideally, a single error-free reference test, known as a gold standard, is used to determine the final diagnosis and estimate the accuracy of the test or diagnostic model under evaluation. If the reference standard does not perfectly correspond to true target disease status, estimates of the accu...

PURPOSE The objectives of this study were to survey the radiographic exposure parameters, to measure the patient doses for intraoral dental radiography nationwide, and thus to establish the diagnostic reference levels (DRLs) in intraoral dental X-ray examination in Korea. MATERIALS AND METHODS One hundred two intraoral dental radiographic machines from all regions of South Korea were selected...

Background Measurement of plasma metanephrines is regarded as one of the best screening tests for phaeochromocytoma/paraganglioma. Current guidelines recommend that samples are ideally collected in the supine position after 30 min rest and interpreted using supine reference ranges, in order to optimize the diagnostic performance of the test. Current practice in our centre is to collect samples ...

background: in diagnostic radiology there are two reasons for measuring or estimating radiation doses to patients. firstly measurements provide a means for setting and checking standards of good practice as an aid to the optimization of patient protection. secondly estimates of the absorbed dose to tissue and organs in the patients. materials and methods: a total of 2382 patients were studied t...

A number of computer-based systems with diagnostic capabilities have been developed for internal medicine. Quick Medical Reference (QMR) is one such program. The authors describe key features of QMR and report on their study of its effectiveness as a diagnostic tool. They investigated how frequently the correct diagnosis would appear among the 5 highest ranked diagnoses generated by QMR. The ch...

OBJECTIVE To propose Irish CT diagnostic reference levels (DRLs) by collecting radiation doses for the most commonly performed CT examinations. METHODS A pilot study investigated the most frequent CT examinations. 40 CT sites were then asked to complete a survey booklet to allow the recording of CT parameters for each of 9 CT examinations during a 12-week period. Dose data [CT volume index (C...
