- Reconsideration of urine culture for the diagnosis of acute pyelonephritis in children: a new challenging method for diagnosing acute pyelonephritis
- Jun Ho Lee, Seonkyeong Rhie
- Clin Exp Pediatr. 2019;62(12):433-437. Published online October 18, 2019
-
Acute pyelonephritis (APN) should be detected and treated as soon as possible to reduce the risk of the development of acquired renal scarring. However, in the medical field, urine culture results are not available or considered when the prompt discrimination of APN is necessary and empirical treatment is started. Furthermore, urine culture cannot discriminate APN among children with febrile urinary...

- Validity of bag urine culture for predicting urinary tract infections in febrile infants: a paired comparison of urine collection methods
- Geun-A Kim, Ja-Wook Koo
- Clin Exp Pediatr. 2015;58(5):183-189. Published online May 22, 2015
-
Purpose Catheter urine (CATH-U) and suprapubic aspiration (SPA) are reliable urine collection methods for confirming urinary tract infections (UTI) in infants. However, noninvasive and easily accessible collecting bag urine (CBU) is widely used, despite its high contamination rate. This study investigated the validity of CBU cultures for diagnosing UTIs, using CATH-U culture results as the gold standard.
Methods We retrospectively analyzed 210 infants,...

Purpose : Taurine (2-aminoethanesulfonic acid) is a simple sulfur-containing amino acid. It is abundantly present in tissues such as brain, retina, heart, and skeletal muscles. Current studies have demonstrated the neuroprotective effects of taurine, but limited data are available for such effects during neonatal period. The aim of this study was to determine whether taurine could reduce hypoxic-ischemic (HI) cerebral... -

- Factors affecting the contamination of bag urine culture in febrile children under two years
- Wook Hyun Choi, In Seok Lim
- Clin Exp Pediatr. 2009;52(3):346-350. Published online March 15, 2009
-
Purpose : Since children under two years with suspected urinary tract infections (UTIs) cannot control urination, urine cultures in such children are usually performed via urine bags. This method is noninvasive but has a high contamination rate. We studied the contamination rate of bag urine culture in diagnosing UTI in infants under two years and the factors responsible for contamination. Methods... -

Even though we drink and excrete water without recognition, the amount and the composition of body fluid remain constant everyday. Maintenance of a normal osmolality is under the control of water balance which is regulated by vasopressin despite sodium concentration is the dominant determinant of plasma osmolality. The increased plasma osmolality (hypernatremia) can be normalized by the concentration of urine,... -

Alkaptonuria is a rare metabolic disease in which homogentisic acid cannot be metabolized due to a lack of the enzyme homogentisic acid oxidase. The disease often manifests itself in childhood by darkening of the urine upon standing. The disease leads to such serious consequences as ochronosis of cartilage and connective tissues with arthritis. It is expected that treatment with ascorbic... -

Maple syrup urine disease is an autosomal recessive disease caused by a deficiency of the branched-chain α-ketoacid dehydrogenase complex. The disease is often suspected because of the peculiar odor of maple syrup in urine. Maple syrup urine disease is usually confirmed by amino acid analysis and urine organic acid analysis showing marked elevations of leucine, isoleucine, valine, and respective ketoacids in... -

Iron is an essential element which participates in a variety of vital processes as well as hemoglobin synthesis of human body. Its hemeostasis is unique in that it is regulated primarily by absorption and not by excretion. Since the capacity of excreted iron is very limited, its absorption from the intestine must be controlled so that tissue accumulations do not reach. In adult males,... -
