PURPOSE: We aimed to investigate the correlation between serum cystatin C and clinical manifestations in pediatric patients with urinary tract infections (UTIs). METHODS: We studied 137 patients admitted with UTIs from June 2012 to May 2014. Depending on the presence of renal cortical defects on 99m Tc-dimercaptosuccinic acid scintigraphy, we classified patients into non-renal and renal defect groups. Laboratory and clinical parameters were analyzed, including the levels of serum cystatin C. The correlation between cystatin C and other variables was assessed. RESULTS: Serum cystatin C levels did not differ between the non-renal and renal defect groups. In both groups, serum cystatin C levels increased after 4-5 days of treatment, compared with the level at admission (P<0.001). However, mean levels were within normal ranges. The concentration of serum cystatin C positively correlated with serum creatinine and negatively correlated with age (P<0.05). In contrast, there was no correlation between serum cystatin C and other variables. CONCLUSION: Serum cystatin C does not appear to be a useful biomarker for renal defects in pediatric patients with UTIs. Further studies are necessary to conclude whether serum cystatin C is helpful in predicting deterioration in renal function in pediatric patients with UTIs.

PURPOSE: This study was undertaken to correlate the CT and histopathologic findings of abscess wall. MATERIALS AND METHODS: The CT findings of 12 patients with pathologically proven brain abscess were retrospectively analyzed with particular attention to the thickness, smoothness and uniformity of enhancing abscess wall, and the results were correlated with histopathologic findings. RESULTS: Two patients with acute cerebritis showed an isodense ring on non-contrast CT(NCCT), but a true capsule formation could not be identified at pathologic examination. Six other patients with isodense ring on NCCT consisted of early to late cerebritis(3 cases), late cerebritis to early capsule(1 case), early capsule(1 case), and late capsule(1 case). These 6 cases showed ring enhancement on contrast enhanced CT(CECT) and true capsule formation pathologically. There was no isodense ring on NCCT in the remaining four patients. They consisted of early to late cerebritis(2 cases), late cerebritis(1 case), and late cerebritis to early capsule formation(1 case). These also showed ring enhancement on CECT and true capsule formation pathologically. CONCLUSION: We found that it is difficult to predict the exact stage of brain abscess on preoperative CT findings. It is suggested that clinical findings and sequential dynamic CT may provide more detailed informations for evaluation of abscess staging.

Renal and perinephric abscesses are a rare but potentially fatal complication of urinary tract infection (UTI). Diagnosing renal and perinephric abscesses has been known to be difficult. These abscesses may occur when the appropriate antibiotic treatment for a UTI is delayed, or in cases with a congenital malformation of the urinary system, especially in children. In the present report, we describe 2 cases of renal abscesses with extra-capsular invasion in children with febrile UTI. A 4-month-old male infant with vesicoureteral reflux developed a renal abscess that infiltrated the perinephric area and the left psoas muscle, despite early antibiotic treatment. A 9-year-old boy with prolonged fever also showed a multi-loculated renal abscess that infiltrated the spleen and diaphragm. Both patients were successfully treated with appropriate antibiotics and percutaneous drainage.

PURPOSE: Helicopter parenting is emerging in parenting as a way of rearing adolescents and adult children. The aims of this study were to develop a Korean version of the Helicopter Parenting and Autonomy Supportive Behaviors Scale (HPASB). METHODS: The HPASB questionnaire items were translated into Korean and reviewed by experts and Content Validity Index (CVI) in a preliminary study with 10 university students. During September and October, 2014 data were collected from 229 nursing students from five different universities in different locations. For data analysis, SPSS 21.0 statistics which included exploratory factor analysis, t-test, one-way ANOVA were utilized. RESULTS: Content validity was over CVI .8. The 6 factors of K-HPASB were extracted and accounted for 59.30% of variance. The Cronbach's alpha coefficient was .71 indicating high reliability. CONCLUSION: The Korean version of the HPASB was identified as a scale with a high degree of validity and reliability. The results of this study provide a valuable scale which can be useful in the study of parenting as a way of rearing adolescents and adult children in Korea. To enhance the positive aspect of helicopter parenting, we suggest the development of intervention programs on parenting.

Herein, a new left renal vein stenting procedure (expandable metallic stent placement), which provided relief for an 18-year-old man incapacitated by an intermittent gross hematuria, is reported. The placement of an expandable metallic stent is a minimally invasive therapy, and a simpler and more physiological therapy than previous approaches to Nutcracker syndrome.

Typhoid fever can cause serious complications, such as enterobrosia, meningitis, pneumonia, myocarditis, hepatitis, osteomyelitis, and disseminated intravascular coagulation in 10-15% of the patients. Kidney complications are very rare, and a few cases have been reported in children. We are reporting a case of childhood typhoid fever complicated with acute nephritis present with albuminuria, hypertension, and renal failure.

A traumatic pulmonary pseudocyst is a rare complication of blunt thoracic trauma. The clinical symptoms and signs are similar to other respiratory diseases, such as pulmonary tuberculosis. Therefore, a trauma history with the resulting radiologic and clinical findings is important for making a diagnosis. A 26-year-old male was admitted to our hospital due to cough for 3 days. The chest x-ray revealed diffuse infiltrations and a cavitary lesion at the left lung. His left chest had hit a tree as a result of motorcycle accident one day before admission. Initially, it was assumed that his symptoms and chest X-ray might be due to a tuberculosis infection. However, bronchoscopy revealed old blood clots at both lungs, particularly in the left lower lobe bronchus. A transbronchial lung biopsy showed alveolar hemorrhage. A traumatic pulmonary pseudocyst was diagnosed from his trauma history and these findings. Computed tomography of the chest performed 4 months later showed regression of the cavitary lesion.

Grisel syndrome is a rare, non-traumatic atlanto-axial subluxation associated with an inflammatory or infectious process in the upper neck. According to the two-hit hypothesis, which is widely accepted for the pathogenesis of Grisel syndrome, preexisting ligamentous laxity of the atlanto-axial joint is regarded as the first hit. An inflammatory or infectious process of the atlanto-axial joint acts as the second hit, resulting in non-traumatic atlanto-axial subluxation. We report on a 6-year-old girl with atlanto-axial subluxation following retropharyngeal and cervical lymphadenitis. She was diagnosed with Grisel syndrome, for which an initial computed tomography did not show any preexisting ligamentous laxity of the atlanto-axial joint. A literature review found only 4 case reports on Grisel syndrome with an initially normal atlanto-axial joint. The present case offers some evidence that a single hit, such as inflammatory changes in the atlanto-axial joint, might cause Grisel syndrome, even without underlying ligamentous laxity.

Ticlopidine is an inhibitor of platelet aggregation used in the management and prevention of thromboembolic disorders. Hematological toxicity is one of the most important side effects of ticlopidine, including neutropenia, thrombocytopenia and more seriously aplastic anemia. We reported here two cases of very severe aplastic anemia developed after the use of ticlopidine. Both patients suffered from an acute cerebral infarction. Both patients developed pancytopenia 56 days and 51 days after treatment with 500 mg of ticlopidine daily. Both patients were hospitalized and received empiric antibiotic therapy and G-CSF. Twenty-three days and thirty days after the withdrawal of ticlopidine, the hematologic parameters of each patient improved.

Cytologic findings from five cases with variable types of Hodgkin's disease were reviewed with special emphasis on the Reed-Sternberg (R-S) cells and their variants, Typical R-S and Hodgkin's cells were mono- or binucleated, and nuclei had rounded smooth con- tour. Acidophilic prominent nucleoli with perinucleolar halo were conspicuous. In comparison to typical Reed-Sternberg cells, L & H (lymphocytic and histiocytic) cells in the lymphocyte predominant type tended to show pop-corn like irregular nuclear contour and to lack the prominent nucleoli. Lacunar cells in the nodular sclerosis type had multilobated nuclei with prominent acidophilic nucleoli. There was no prominent perinucleolar halo in L & H and lacunar cells. In conjuction with the number of Reed-Sternberg cells and back ground findings observed on the smears, the characteristic features of R-S cells and their variants allowed to make typing of Hodgkin's disease.
