The congenital renal cystic disease encompasses a complex group of pathologic and clinical entities. We retrospectively reviewed 42 cases of congenital renal cystic lesions classified into four Potter types in a series of 2,063 consecutive autopsies from 1981 to 1996. According to our study based on morphologic, clinical, genetic features and associated anomalies, type I and III are relatively compatible with Potter's original definition. However, it was reasonable that type II and IV are classified to the same group because of: 1) very similar histologic findings representing dysplastic kidney, 2) many associated anomalies, 3) no evidence of inheritance, and 4) presence of a combined type. Syndrome associated cysts, such as Meckel-Gruber syndrome, were also separately classified. If the dysplastic evidence was insufficient for diagnosis to the dysplastic kidney in type II and IV, then these cases would be better classified into a cystic disease associated with congenital hydronephrosis. We propose a classification of the congenital cystic disease of the kidney to be: 1) dysplastic kidney, 2) cystic disease associated with congenital hydronephrosis, 3) polycystic kidney, and 4) syndromic cystic disease.

A case of congenital absence of right atriovntricular (A-V) connection of heart is reported. Patient was 81 day old male infant with chief complaints of dyspnea and irritability. Clinical evaluation revealed increased pulmonary vascularity on chest x-ray, absence of right A-V connection, regurgitation of left A-V valve, right-sided ventricular hypoplasia and L-TGA. Clinical assessment of the case was tricupsid atresia with LTGA and mitral regurgitation. Pulmonary artery banlding and artial septectomy was performed. Parenteral alimentation through the femoral veins resulted in obstruction of IVC and subsequent multiorgan failure. The autopsy findings of the heart were corrected transposition of great arteries with associated anomallies of right-sided mitral atresia, Ebstein's malformation of left-sided tricuspid valve, ventricular septal defect, muscular hypertrophy of right-sided left ventricle with luminal obliteration. Long segment of IVC was completely occluded due to occlusive thrombi with fungal infection. Bilateral kidneys were infarcted and azygos vein was markedly engorged. Microscopic examination revealed candidal colonization in the inferior vena cava and septic embolzation in brain.

For the success of complete denture, three essential requirements such as retention, stability and support are needed. Moreover, due to the absorption of residual ridge and scarring due to the surgery, when making a complete denture, which is difficult to form the mandibular lingual margins, various considerations such as the arrangement of the Non-anatomical dl non-anatomical teeth, the polished surface impression, the internally weighted metal framework and the use of the denture adhesive cream are necessary. In this case report, the patient has a severely resorbed edentulous ridge from severe periodontitis and has some soft tissue problems after the glossectomy due to tongue cancer. To obtain additional retention and stability, some trials such as polished surface impression taking, internally weighted metal insertion and minimal pressure impression were done for the better result. Moreover To make a metal framework that precisely shapes the desired three-dimensional shape and reduces the complicated process, minimal pressure impression method and direct metal laser sintering technique were used.

BACKGROUND AND OBJECTIVES: The incidence of retropharyngeal abscess has been decreased with use of antibiotics, but it still causes critical complications such as airway obstruction, aspiration pneumonia, mediastinitis, or sepsis. For this reason, early diagnosis and proper management of retropharyngeal abscess should be undertaken as soon as possibile. The treatment includes maintaining airway, performing surgical drainage, and administering antibiotics; but there are no definite guidelines for treating patients with retropharyngeal abscess, nor a golden rule for the correct surgical approach. SUBJECTS AND METHOD: A retrospective analysis of patients with retropharyngeal abscess who were treated at the Chungbuk University Hospital from 1993 to 2003 was performed. We analized general symptoms, signs, causing factors, and causing bacteria. We also analized the treatment outcome and selected approaches from the surgically treated patients. RESULTS: The general symptoms of retropharyngeal abscess were sore throat, fever, dyspnea, with the most common cause being the upper airway infection. Bacteriologically, hemolytic streptococcus was the most common bacteria among aerobes and bacteroides was the most common bacteria among anaerobes. However, in most cases, both aerobe and anaerobes were cultured at the same time. Among 18 cases, 6 cases were treated conservatively with antibiotics and surgical interventions were performed in 12 cases, which included 11 cases of transoral and 1 case of transcervical approach. CONCLUSION: Retropharyngeal abscess can be treated with either conservative or surgical treatment according to initial abscess size. The abscess size which is greater than 3 cm is prefered to be treated surgically, and transoral approach is a useful way of dealing with less invasive procedure.

Background: This study investigated the longitudinal associations between the degrees of positive and negative spillover in work–life balance (WLB) at baseline and reports of depressive mood at a 2-year follow-up in Korean women employees. Methods: We used a panel study design data of 1386 women employees who participated in the Korean Longitudinal Survey of Women and Families in both 2014 and 2016. Depressive mood was measured using the “10-item Center for Epidemiologic Studies Depression Scale.” Associations between the positive and negative spillover in WLB at baseline and reports of new incidence of depressive mood at 2-year follow-up were explored using a multivariate logistic regression model. Results: Negative spillover in WLB at baseline showed a significant linear association with reports of depressive mood at 2-yearfollow-up after adjusting for age, education level, marital status, number of children, and positive spillover (P = 0.014). The highest scoring group in negative spillover (fourth quartile) showed a significant higher odds ratio of 1.95 compared with the lowest scoring group (first quartile; P = 0.036). Conclusion Positive spillover in WLB showed a U-shaped association with depression. The degrees of positive and negative spillover in WLB among Korean women employees at baseline were associated with new incidence of depressive mood within 2 years. To prevent depression of female workers, more discrete and differentiated policies on how to maintain healthy WLB are required.

PURPOSE: We wanted to determine the incidence and characteristics of failing graft after implantation of autologous reversed vein grafts. METHOD: From Sep. 2003 to Dec. 2005, 84 leg bypasses using autologous reversed vein grafts were performed for chronic leg ischemia in 75 patients. After the operations, duplex ultrasonography (DUS) and measurement of the ankle brachial index (ABI) were performed every 3 months for the purpose of examining the graft patency. The criteria for a failing graft was a peak systolic velocity (PSV) of the stenotic lesion >300 cm/s, or a PSV distal to the occlusive lesion <40 cm/s, but with sustained patency of the vein graft. We investigated the timing of detection, the site of the causative lesion, and the clinical symptoms of the failing grafts. For the treatment of failing grafts, surgeries (vein patch, graft extension, or inflow artery reconstruction) were performed in 4 legs. The Kaplan Meier method was used for calculating the rate of graft patency. RESULT: Nine failing grafts were detected by DUS in 8 patients. The sites of causative lesions were the inflow artery (2), the proximal anastomosis (6), and the distal anastomosis (1). Seven of the 9 patients with failing grafts were asymptomatic, 1 patient had claudication and another patient suffered from resting pain of the involved leg. The assisted graft primary patency rates at 1 and 2 years after operations were 86% and 53%, respectively. CONCLUSION: Nine cases of failing grafts were detected during surveillance with duplex ultrasonography after implantation of autologous reversed vein grafts.

OBJECTIVE: The aim of the present study was to investigate the visual perception difference between ADHD children with and without sensory processing disorder, and the relationship between sensory processing and visual perception of the children with ADHD. METHODS: Participants were 47 outpatients, aged 6-8 years, diagnosed with ADHD. After excluding those who met exclusion criteria, 38 subjects were clustered into two groups, ADHD children with and without sensory processing disorder (SPD), using SSP reported by their parents, then subjects completed K-DTVP-2. Spearman correlation analysis was run to determine the relationship between sensory processing and visual perception, and Mann-Whitney-U test was conducted to compare the K-DTVP-2 score of two groups respectively. RESULTS: The ADHD children with SPD performed inferiorly to ADHD children without SPD in the on 3 quotients of K-DTVP-2. The GVP of K-DTVP-2 score was related to Movement Sensitivity section (r=0.368*) and Low Energy/Weak section of SSP (r=0.369*). CONCLUSION: The result of the present study suggests that among children with ADHD, the visual perception is lower in those children with co-morbid SPD. Also, visual perception may be related to sensory processing, especially in the reactions of vestibular and proprioceptive senses. Regarding academic performance, it is necessary to consider how sensory processing issues affect visual perception in children with ADHD.

The intrahepatic calculi are prevalent in east Asia and are regarded as malignant disease because diagnosis and treatment are difficult and complication and mortality are high. This study is a retrospective clinical review of 58 cases of patient with intrahepatic calculi in the Department of Surgery, Chungnam National University Hospital from July 1994 through June 1999. The incidence of intrahepatic calculi was 8.8% of total hepatobiliary calculi. The ratio of male to female was 1:2.4. The peak incidence was noted at the 6th decade (32.7%) and mean age was 52.1 years. About the site of stones, left intrahepatic duct (48.3%)was more prevalent than right intrahepatic duct (17.2%). 42 cases(72%) of the intrahepatic calculi were associated with GB stone(8%), CBD stone(45%) or both(19%). As to surgical method, choledochotomy with T-tube drainage was performed in 34 cases(59%), choledochoduodenostomy was in 3 cases(5%) and hepatic resection in 21 cases(36%). Among them choledochotomy with T-tube drainage was the most frequently performed procedure. The remnant stones are most commonly founded after choledochotomy and T-tube drainage (80%) followed after choledochoduodenostomy(33%) and after hepatic resection(24%). But, major postoperative complications such as bile leakage and intra-abdominal abscess are more frequent in casea of hepatic resection. So we suggest that agressive treatment modality such as hepatic resection is more reasonable than drainage procedure in the management of intrahepatic duct stone by the experienced expert.
