Purpose: Attention deficit hyperactivity disorder (ADHD) has been associated with impairments in frontal inhibitory function and the catecholaminergic system. ADHD is diagnosed in 3-5% of children. Children with ADHD seem develop various forms of urinary problems such as nocturnal enuresis, dysfunctional voiding, and diurnal incontinence. However, no data exist to confirm the presence of these problems in Korean children with ADHD. We investigated the clinical findings of voiding dysfunction in children with ADHD. Methods: Between October 2009 and March 2011, a total of 63 children (33 with ADHD, 30 with an upper respiratory infection, as a control group) were enrolled. ADHD was diagnosed using the diagnostic and statistical manual of mental disorders (DSM)-IV criteria. A comprehensive survey of voiding and defecation was administered. Results: The patient group included 28 boys and 5 girls; the control group comprised 20 boys and 10 girls. The mean age was $9.09{\pm}2.8$ years in the ADHD group and $8.58{\pm}3.1$ years in the control group. Children with ADHD had a statistically significantly higher incidence of urgency (P =0.017), urge incontinence (P =0.033), and constipation (P =0.045). There was no significant difference in the incidence of straining, intermittency, holding maneuvers, or nocturnal enuresis. Conclusion: Children with ADHD in Korea have significantly higher rates of urgency, urge incontinence, and constipation than those without ADHD.
Backgroud. To determine the influence of age at operation upon surgical outcome in patients with isolated secundum atrial septal defect, retrospective clinical analysis was done. Material and method. From June, 1976 to December, 1991, 146 patients, 63 male and 83 female patients ranging in age from 13 months to 56 years, were operated on for isolated secundum atrial septal defect. The patients were divided into 3 groups according to their age at operation: Group I [<20 years old], 91 patients[62.3%]; Group II [21 to 40 years old], 44 patients[30.1%]; GroupIII[>41 years old], 11 patients[7.6%]. Significant differences in clinical features, hemodynamic function, early and late results between age groups were speculated. Results. One hundred thirty-one patients[89.6%] were symptomatic at the time of operation, the most common symptoms being dyspnea on exertion, recurrent respiratory infection, palpitation and chest pain. Patients in NYHA class III or IV were 3.3% in group I, 25% in groupIII, and 54.5% in group Ill. Hemodynamic data was available for 138 patients [94.5%]. Significant pulmonary hypertension [MPA systolic pressure $^3$ 40mmHg] was noted in 22 patients [15.9%]. Patients with pulmonary vascular disease [Rp/Rs>1.25] were 2% in group I, 7.3% in group Il, and 9.1% in groupIII. But there were no significant differences between the age groups in the size of the shunt or the ratio of pulmonary to systemic flow. Atrial septal defects were closed with direct suture in 144 patients and patch repair was performed in 2 patients with high defect. Atrial arrhythmia [8.2%] was the most common postoperative complication. The mean [LSD] duration of follow-up in all patients was 16$\pm$22 months [range, 1~96 months]. Functional result was excellent regardless of the age groups. During follow-up period, late cardiovascular events were arrhythmia [7 cases], reoperation for recurrent ASD [2 cases], and premature late death due to bacterial endocarditis [1 case]. Incidence of preoperative and late atrial fibrillation was significantly higher in older age group. Conclusion. Age at operation is one of the most important predictor of early and late surgical outcome with its impact on the following factors : 1] hemodynamic alterations and ventricular dysfunction due to longstanding volume and pressure overload, 2] pulmonary vascular disease, and 3] atrial arrhythmia including atrial fibrillation as a result of atrial dilatation. Therefore, among patients with surgically repaired atrial septal defects, those operated on over the age of 20 require careful supervision on the long-term basis.
Purpose: Gastroschisis and omphalocele are major anterior abdominal wall defects. The purpose of this study was to analyze the clinical differences and mortalities of gastroschisis and omphalocele in Asan Medical Center. Methods: A retrospective review of the medical records was conducted of 103 cases of gastroschisis and omphalocele from September 1989 to February 2013 in Asan Medical Center in Korea. Results: There were 43 cases (41.7%) of gastroschisis and 60 cases (58.3%) of omphalocele. There was a female predominance in both gastroschisis (60.5%) and omphalocele (58.3%). The average gestational age at delivery was $36.7{\pm}0.4$ weeks for both groups. The mean birth weights were $2,381.9{\pm}80.6g$ for gastroschisis and $2,779.4{\pm}82.8g$ for omphalocele (p=0.001). Mean maternal ages in the gastroschisis and omphalocele groups were $27.5{\pm}0.7$ years and $30.5{\pm}0.7$ years, respectively (p=0.002). Associated malformations were documented in 13 infants (30.2%) with gastroschisis and 46 infants (76.7%) with omphalocele (p<0.001). All of gastroschisis patients except one underwent surgery including 31 primary repairs and 11 staged repairs. Fifty-two infants with omphalocele underwent surgery-primary repair in 41 infants and staged repair in 11 infants. Among 103 cases, 19 cases (18.4%) expired. Mortality rates of gastroschisis and omphalocele were 23.3% (10/43 cases) and 15.0% (9/60 cases), respectively (p=0.287). The main causes of death were abdominal compartment syndrome (6/10 cases) in gastroschisis, respiratory failure (4/9 cases) and discharge against medical advice (4/9 cases) in omphalocele. Conclusion: Gastroschisisis was associated with younger maternal age and lower birth weight than omphalocele. Associated malformations were more common in omphalocele. The mortality rates did not make a statistical significance. This might be the improvement of treatment of cardiac anomalies, because no patient died from cardiac dysfunction in our study. Furthermore, abdominal compartment syndrome might be the main cause of death in gastroschisis.
Endobronchial tuberculosis is frequently associated with lymphadenopathy, bronchial stenosis, atelectasis which needs to be differentiated with other pulmonary disease. Authors are presenting 25 cases of endobronchial tuberculosis which were confirmed by bronchoscopic biopsy and AFB smear and/or culture. The study was done on patients who visited Yeungnam University Hospital from May 1983 to July 1985. The following results were obtained: 1. Of the 25 cases, 8 cases were male and 17 cases were female (male : female= 1 : 2). 32 percent of the cases was older than 60 years of age. 2. Abnormal findings on chest x-ray were seen on 22 cases of 25 cases (88%) and its most predilective site was right upper lobe.(24%). 3. Symptoms were coughing (56%), hemoptysis, hoarseness, chest pain, dyspnea and fever in orders. 4. The positive results were obtained in 73 percent of sputum AFB sme ar (11 cases of 15 cases), 60 percent of AFB culture (3 cases of 5 cases) and 58 percent of bronchoscopic biopsy (14 cases of 24 cases). 5. Complete pulmonary function test was done on 19 cases and showed normal result in 6 cases, restrictive pattern in 8 cases and small airway dysfunction in 5 cases. No case of obstructive airway disease was detected. 6. Associated disease were hypertension (2 cases), tuberculous meningitis (1 case), diabetes mellitus (1 case), and cataract (1 case). 7. The site of bronchoscopic lesion on bronchoscopic examination were as follows; 8. All 25 patients were treated with anti-tuberculosis theyapy and 6 patients were treated with additional steroid therapy because of severe respiratory symptom and showed dramatic improvement of symptom as well as lung function.
The coronavirus disease 2019 pandemic has been continuously spreading throughout the world. As of July 15, 2021, there have been more than 188 million confirmed cases and more than 4.06 million deaths. Although the incidence of severe infections is relatively low in children and adolescents compared to adults, a complication called multisystem inflammatory syndrome in children (MIS-C) may occur in some cases at approximately 2-6 weeks after severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. MIS-C can be seen in patients of various ages, from young infants to adolescents, and may present with diverse clinical manifestations. While fever present in a great majority of patients, symptoms suggesting the involvement of the digestive or nervous system and the skin and mucous membranes (Kawasaki disease-like symptoms) also appear in many cases. Cardiac involvement may also be observed, including left ventricular dysfunction, myocarditis, coronary artery dilatation, and coronary aneurysm. In some cases, hypotension or shock can occur, and mechanical ventilation or treatment in the intensive care unit may be necessary. Fortunately, recovery is generally reported after appropriate treatment. MIS-C is a rare but important complication of SARS-CoV-2 infection in children and adolescents. As such, it is important to recognize the clinical symptoms and provide appropriate treatment at an early stage. In this review, the epidemiology, clinical symptoms, suggested pathophysiology, diagnostic approach, and treatment of MIS-C will be discussed.
Background: Effective strategies are dramatically needed to prevent and improve the recovery from myocardial ischemia and reperfusion (I/R) injury. Direct interactions between the mitochondria and endoplasmic reticulum (ER) during heart diseases have been recently investigated. This study was designed to explore the cardioprotective effects of gypenoside XVII (GP-17) against I/R injury. The roles of ER stress, mitochondrial injury, and their crosstalk within I/R injury and in GP-17einduced cardioprotection are also explored. Methods: Cardiac contractility function was recorded in Langendorff-perfused rat hearts. The effects of GP-17 on mitochondrial function including mitochondrial permeability transition pore opening, reactive oxygen species production, and respiratory function were determined using fluorescence detection kits on mitochondria isolated from the rat hearts. H9c2 cardiomyocytes were used to explore the effects of GP-17 on hypoxia/reoxygenation. Results: We found that GP-17 inhibits myocardial apoptosis, reduces cardiac dysfunction, and improves contractile recovery in rat hearts. Our results also demonstrate that apoptosis induced by I/R is predominantly mediated by ER stress and associated with mitochondrial injury. Moreover, the cardioprotective effects of GP-17 are controlled by the PI3K/AKT and P38 signaling pathways. Conclusion: GP-17 inhibits I/R-induced mitochondrial injury by delaying the onset of ER stress through the PI3K/AKT and P38 signaling pathways.
Background : Activation of neutrophil is critical for the clearance of microorganisms and toxic host mediators during sepsis. Unfortunately the activated neutrophil and its toxic byproducts can produce tissue injury and organ dysfunction. The leucocyte CD11/18 adhesion complex regulates neutrophil-endothelial cell adhesion, the first step in neutrophil migration to sites of injection and inflammation. To investigate the potential of neutrophil inhibition as a treatment strategy for sepsis, we evaluated the effects of monoclonal antibody against CD11b (MAb 1B6) in rats intrabronchial challenged with Escherichia coli. Methods : Animals were randomly assigned to receive monoclonal antibody against CD11b (1 mg/kg, sc) and bovine serum albumin(BSA, 1 mg/kg, sc) 6 hr before, at 0 and 6 hr after intrabronchial challenge of $20x10^9$ CFU/kg E. coli 0111. Animals were randomized to treat either 24, 60 or 90% oxygen after bacterial challenge and begining 4 hr after inoculation, all animals were received 100 mg/kg ceftriaxone qd for 3 days. Peripheral and alveolar neutrophil(by bronchoalveolar lavage) counts and lung injury parameters such as alveolar-arte rial $PO_2$ difference, wet to dry lung weight ratio and protein concentration of alveolar fluid were measured in survived rats at 12 hr and 96 hr. Results : Monoclonal antibody against CD11b decreased circulating and alveolar neutrophil especially more in 12 hr than in 96 hr The lung injury parameters of antibody-treated animals were not different from those of BSA-treated animals. but It was meaningless due to small number of survived animals. The early(6 hr) mortality rate was significantly increased in antibody-treated group(51%) compared to BSA-treated group(31%) (P=0.02) but late(from 12 hr to 72 hr) mortality rate was not different in antibody-treated group(44%) from BSA-treated group(36%) (P =0.089). Conclusion : Leucocyte CD11b/18 adhesion molecule is known to regulate neutrophil migration to the site of infection and inflammation. The monoclonal antibody against CD11b decreased alveolar neutrophil in rats with pulmonary sepsis and increased early mortality rate. Therefore, we can speculate that monoclonal antibody against CD11b blocks of alveolar recruitment of neutrophils, impairs host defense mechanism and increases early mortality rate of pulmonary sepsis in rat.

Background: Lung cancer is the leading cause of cancer death in South Korea since the year 2000 and it is more common in elderly patients, with a peak incidence at around 70~80 years of age. However, these elderly patients receive treatment less often than do the younger patients because of organ dysfunction related to their age and their comorbidities, and they show poor tolerance to chemotherapy. The aims of this study were to analyze the clinical characteristics and treatment-related survival of elderly patients with lung cancer. Methods: In this retrospective study, we analyzed the clinical data of 706 lung cancer patients who were diagnosed at hospitals in Daegu and Gyeongsangbukdo from January 2005 to December 2005. We compared the clinical characteristics and outcomes of the patients who were aged 70 years and older (elderly patients) with those clinical characteristics and outcomes of the younger individuals. Results: The median age of the patients was 68 years (from 29 to 93) and the elderly patients were 38.7% (n=273) of all the study's patients. Squamous cell carcinoma was the most common type of lung cancer in both the elderly and younger patient groups. Elderly patients had more symptoms of dyspnea and chronic obstructive pulmonary disease (COPD) than the younger patients (p<0.001 and p<0.001, respectively). A good performance status (ECOG 0-1) was less common for the elderly patients (p<0.001). The median survival of the non-small cell lung cancer (NSCLC) patients was significantly higher in the younger patient group than in the elderly patient group (962 days vs 298 days, respectively, p=0.001). However, the median survival of the NSCLC patients who received any treatment showed no significant difference between the younger patient group and the elderly patient group (1,109 days vs 708 days, respectively, p=0.14). Conclusion: Our data showed that appropriate treatment for selected elderly patients improved the survival of patients with NSCLC. Therefore, elderly NSCLC patients with a good performance status should be encouraged to receive appropriate treatment.
Background : The serum B-type natriuretic peptide (BNP) is released from the ventricles as a response to volume or pressure overload of the ventricles. A few studies have reported that the BNP measurements are useful in differentiating between heart failure and pulmonary causes in patients who visited the emergency department with dyspnea as the chief complaint. It is difficult to differentiate a right heart failure from a left heart failure in the emergency room. However, there is no report on the application of a BNP assay to differentiate in right heart failure from left heart failure. In this study, the BNP levels were measured from dyspneic patients in the emergency department to determine whether or not the BNP level would be useful in differentiating the cause of the dyspnea from right ventricular failure and left ventricular failure. Method : 89 patients who visited emergency department of the Bundang Cha Hospital with dyspnea from June 2002 to March 2003 were selected. The 29 patients from the outpatient clinics and inpatients were randomly selected as the control. Results : The BNP levels of patients in the left heart failure group were significantly different from that of the patients in the right heart failure group ($682{\pm}314$ pg/mL vs. $149{\pm}94$ pg/mL, p=0.000). When the BNP cut-off level was designated as 219 pg/mL using the receiver operating characteristic curve, the sensitivity was 94.3%, and specificity was 92.9%. In addition, the positive predictive value was 97% and the negative predictive value was 86.7% in differentiating right heart failure from left heart failure. Conclusion : Measurements of the serum BNP levels is an accurate and rapid method that can aid in distinguishing between right heart failure and left heart failure.

Purpose : We have done this retrospective study to know the relative incidence and clinical manifestations of organic acidopathies in Korea during 8 years(from Jul. 1997 to May 2005). This results of organic acid analysis of 1,787 patients were compared with the results of organic acid analysis that were published three years ago. Methods : The results of quantitative organic acid analysis of samples of 1788 patients, referred from Jul. 1997 to May 2005, were analyzed retrospectively according to four age group(-2 mon, 3 mon-2 years, 3-12 years) and major clinical manifestations. Quantification of 83 organic acids was done with gas chromatography and mass spectometry. Results : We diagnosed 470 patients with 27 diseases of organic acid metabolism during this study period. Diseases found more than 10 cases are cytosolic 3-ketothiolase deficiency, mitochondrial respiratory chain disorders, PDHC deficiency, mitochondrial 3-ketothiolase deficiency, glutaric aciduria type II, biotinidase deficiency, methylmalonic aciduria and propionic aciduria. Other diseases were diagnosed in less than 10 cases. Conclusion : Though the incidence of individual organic acidemia is low, the overall incidence of organic acidemia as a whole seems to be relatively high in Korea. Compared with the results of organic acid analysis that were reported three years ago, we couldn't find a new disease and the difference of the relative incidences of high incident diseases. We were apprehensive of the errors that was owing to the short study period(3 years), but the relative incidences of our study(8 years) were similar to the results of organic acid analysis that were reported three years ago.
