BACKGROUND: Urinary tract infections (UTIs) are the most frequent nosocomial infections and are frequently associated with indwelling urinary catheters. It is known that adherence to standard infection control measures for urinary catheters can reduce UTIs in hospitals. This study was performed to evaluate the effect of education in reducing catheter-related UTIs (CR-UTIs) in intensive care units (ICUs) of a university hospital. METHODS: CR-UTIs were prospectively monitored for all patients with indwelling urinary catheters in ICUs from July 2006 through December 2007. Recommendations based on previously known guidelines for catheter insertion, catheter management, and specimen collection to prevent CR-UTIs were formulated and educated in March 2007. Knowledge and adherence level were evaluated before and after educating healthcare workers about the recommendations using questionnaire. Changes in knowledge and adherence level before and after education were compared by Chi-square test. Changes in the rate of CR-UTIs and urinary catheter utilization ratios were also analyzed by Fisher's exact test. RESULTS: After education, knowledge level of and adherence level to most of the recommendations were improved significantly. The rate of CR-UTIs significantly decreased by 48% from 7.43/1,000 catheter-days before intervention to 3.87/1,000 catheter-days after intervention (P=0.02). CONCLUSION: Surveillance for nosocomial infections and education for standard infection control measures are very important in preventing CR-UTIs in ICUs.

PURPOSE: To identify the characteristic ultrasonographic findings of the normal appendix in children in order to detect it more easily and so to exclude acute appendicitis from a diagnosis with more confidence. MATERIALS AND METHODS: Among 64 patients presenting with right lower quadrant pain, 44 patients, excluding 15 patients diagnosed as acute appendicitis and 5 patients with non-visualization of the appendix due to severe ileus and obesity, were evaluated for the point of incidence, the thickness and the presence of folding of the inner hypoechoic band of the normal appendix. The age of the patients ranged from 3 to 15 years with a mean age of 6.5 years. Two patients were operated on and we correlated the preoperative ultrasonographic findings with the histologic findings. RESULTS: In all the cases of the 44 patients with normal appendix, the inner hypoechoic band was discovered, which was seen as a linear structure without folding along the whole length of appendix. This measured as 0.75 mm (0.3-1.5 mm) for the mean thickness. The inner hypoechoic band corresponded to the mucosal layer that had abundant lymphoid tissue on the histologic examination. CONCLUSION:For the pediatric normal appendix, the inner hypoechoic band without folding is present, and this corresponds to the mucosal layer with abundant lymphoid tissue.

VURD syndrome is a disorder characterized by a posterior urethral valve, unilateral reflux, and ipsilateral renal dysplasia. This syndrome is not uncommon, with an incidence in the range of 15 to 20% in patients with posterior urethral valve. Etiology is not clear, but there are a few reports that renal dysplasia is either a result of hydrostatic pressure transmitted to the developing kidney or a common teratogenic factor resulting in urethral obstruction, renal dysplasia, and vesicoureteral reflux. Infants with posterior urethral valves and persistent unilateral reflux after valve resection often have an associated nonfunctioning, dysplastic kidney. Misinterpretation of initial radiographic studies performed without coinciding bladder drainage results in a missed diagnosis of this syndrome and misguided surgical management. Functional assessment by a renal scan with bladder catheter drainage will avoid unnecessary staged or reconstructive procedures. Nephoureterectomy is recommended at about 1 year of age to improve voiding dynamics and to avoid infection. We experienced a case of VURD syndrome, first presenting bilateral hydronephrosis by ultrasonography during the prenatal period. Voiding cystourethrography revealed dilated posterior urethra and left vesicoureteral reflux, and DMSA scan showed a nonfunctioning left kidney.

A statistical analysis of 92 patients with ureteral stones, who had been treated by conservative treatment was undertaken to elucidate the correlation between size of calculi and the probability of spontaneous passage. The overall rate of spontaneous passage was 69.5%. Average stone size and treatment duration were 4.0, 5.0, 4.2mm and 9.4, 10, 6.3days in order of upper. mid, lower ureter. The rate of spontaneous passage according to stone size was 80% in less than 5mm. 15% in 5-6mm and 5% in 6-7mm. Therefore, when stones are smaller than 5mm in diameter, higher chances of spontaneous passage would be anticipated in 6-7days.

PURPOSE: To report a case of suprasellar arachnoid cyst with compressive optic neuropathy. CASE SUMMARY: A 50-year-old man presented with decreased visual acuity in the right eye of 6 months duration. Best corrected visual acuity was 0.2 in the right eye, 1.0 in the left eye, and the intraocular pressure was 13 mm Hg in the right eye, and 18 mm Hg in the left eye. Fundus examination showed pale optic disc in the right eye and retinal nerve fiber layer defects in both eyes. Visual field examination revealed a central visual field of 10degrees in the right eye and an inferior visual field defect in the left eye. The brain magnetic resonance image (MRI) showed a suprasellar arachnoid cyst that compressing the optic nerve and chiasm. CONCLUSIONS: The author experienced arachnoid cyst accompanied by optic disc atrophy and visual field defect in a patient diagnosed and treated for glaucoma. In cases of non-specific clinical features that differ from typical glaucomatous presentations, the utilization of brain MRI appears to be helpful in diagnosis and treatment.

BACKGROUND: Immune thrombocytopenic purpura (ITP) in children less than one year of age is less well characterized compared to ITP in toddlers and school-age children. Since children of different ages may have differing clinical courses, better delineation of the natural history of ITP in infants is needed. METHODS: We retrospectively reviewed the admission records of 248 consecutive pediatric patients between 1 month and 15 years of age who were admitted and treated for acute ITP at Pusan National University Children's Hospital from 2009 through 2017. All patients less than 1 year of age were identified and enrolled in this study. We investigated their demographics, clinical features, laboratory examinations, response to treatment, and long-term outcomes and made a comparison to those of children aged 1 to 10 years of age. RESULTS: Ninety nine infants were identified. Male to female ratio was highest in infants and decreased with age. Seventy nine (79.8%) of the 99 infant were found to be under 6 months old. The median platelet counts at diagnosis was 6×10⁹/L. Minor bleeding (bleeding score 0–2) was significantly dominant in infant compared to older subjects. Eighty two (96.5%) out of 85 patients achieved complete remission after initial intravenous immunoglobulin (IVIG) treatment. The relapse rate after initial CR was significantly lower than older ages (P=0.003). The platelet count after IVIG treatment in infant showed more rapid response compared to older subjects (P=0.04). Follow up information at 12 months was available for 70 infants. Chronic ITP at 12 month was seen less frequently in infants than in children 1 to 10 years of age (1.4% vs. 20.2%, P<0.001). CONCLUSION: Infants with acute ITP respond more favorably to IVIG treatment and are less likely to develop chronic ITP compared to children 1 to 10 years of age.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a very rare hematological malignancy in children that is characterized by bruise-like skin lesions, with or without bone marrow involvement. Because the clinical course of BPDCN is highly aggressive and fatal in adults, allogeneic hematopoietic stem cell transplantation (HSCT) is recommended as the optimal treatment. Due to its rarity, the pediatric experience with BPDCN is limited and standard treatment has so far not been defined. We report a case of a 14-year-old boy with BPDCN involving the skin, bone marrow and lymph nodes. The patient was treated with high-risk group acute lymphoblastic leukemia protocol. He achieved a complete remission after induction chemotherapy and still maintains clinical remission without HSCT for 17 months after initial diagnosis.
