A Case of Perinephric Abscess Treated by Percutaneous Drainage

Perinephric abscess is an accumulation of pus in the perinephric space, the area anatomically defined between the kidney and Gerota's fascia. Gram negative organisms are the most prevalent bacterial species found in perinephric abscess. Fever, flank pain, vomiting and abdominal mass are the usual presenting complaints. But with its insidious onset, variable symptoms and rare frequency in children, perinephric abscess has been a major diagnostic problem, leading to delayed diagnosis and inappropriate treatment, which increase the rate of complication and mortality. Clinical diagnosis of perinephric abscess is difficult but must always be considered in children with a febrile septicemic illness. For appropriate treatment, early detection is very important, and either ultrasonography or computed tomography(CT) facilitates the diagnosis and establishment of treatment method. We experienced a case of left perinephric abscess treated by percutaneous drainage in a 1-year 7-month old boy. Review of literature was made briefly.

A study on the effects of sleep position and of body weight on motor development / 소아과

PURPOSE: This study investigated how gross motor and fine motor development are influenced by sleep position. METHODS: From December, 2003 to September, 2005, for a year and 9 months, 800 children aged from 3 months to 16 months, who visited the Presbyterian Medical Center, Chonju, Korea were surveyed for motor development scale, sleep position and body weight. RESULTS: The sleep position came in order:79.3 percent of supine position, 10.0 percent prone position and 10.7 percent side position. Gross motor scale and fine motor scale were not connected with sex. The prone position indicated remarkable increase on gross motor scale from 5-6 months, but stayed the same after 7 months. Fine motor scale was not related to age and sleep position. Gross motor scale and fine motor scale were higher on group weighing more than under average weight group. CONCLUSION: This study showed that prone position did not influence gross motor scale after 7 months, affecting children of 5-6 months only. Hence, It is not recommended to use the prone position for a baby's fast gross motor development.

A study for headaches and backaches occurrence after diagnostic lumbar puncture in children / 소아과

PURPOSE: Our goals were to determine the frequency of headaches and backaches occurring as a side effect following lumbar puncture in children, and to investigate various factors that might influence the frequency of headaches and backaches. METHODS: From October 2004 to February 2006, we enrolled 148 patients aged 2 to 15 years who received diagnostic lumbar puncture at the Presbyterian Medical Center, Chonju, Korea. Patient data were collected for age, sex, number of puncture attempts, volume of cerebrospinal fluid(CSF), bevel orientation of puncture needle, cell count in CSF, periods of absolute bed rest, and the frequency and duration of headaches and backaches. RESULTS: Headaches occurred in 8 patients and backaches occurred in 40 patients. Headaches were found both to occur significantly more frequently in patients over age 10 and to last longer when the bevel orientation of the puncture needle was inserted toward the cranium rather than laterally. Backaches lasted longer in males than in females. The other factors evaluated showed no relationship at all to the frequency and duration of headaches and backaches. CONCLUSION: Following lumbar puncture, headaches were common in patients over age 10, and lasted longer when the bevel orientation was toward the cranium. Backaches lasted longer in males than in females. In light of these findings, we recommend taking special care when performing lumbar puncture for CSF examination in patients over age 10.
