Incidentally Found Absence of the Left Brachiocephalic Vein with Venous Return Through the Left Superior Intercostal Vein in an Adult Patient: Venography and CT Findings

A 63-year-old male patient was referred for venography of the thoracic venous system and multidetector computed tomography (CT) due to the unusual location of the left subclavian catheter tip. His venogram and CT images showed an absence of the left brachiocephalic vein (LBCV). Instead of through the LBCV, the usual venous circulation of neck and left upper limb was carried out by the engorged left superior intercostal vein (LSIV); this subsequently drained into the accessory hemiazygos vein and then the azygos vein that drains into the superior vena cava. Here, we report a rare case of an incidentally found absence of the LBCV with venous return through the LSIV in an adult patient, and we present a brief review of the relevant literature.

Clinical Findings and Interventional Treatment of Gastrointestinal Fistulae: Pictorial Essay

Gastrointestinal (GI) fistulae are defined as an abnormal communication between the gastrointestinal tract and the skin and/or the epithelial surface of an adjacent viscus. GI fistulae are the most feared complications caused by a variety of medical conditions including abdominal surgery, inflammatory bowel disease, abscess, radiation, or trauma. The management of GI fistulae is complex and requires a detailed, stepwise approach to achieve successful closure. The ultimate goal of management is to re-establish the continuity of the GI tract, while limiting the morbidity and mortality. Interventional radiology can play an important role in the diagnosis and treatment of GI fistulae. In this article, we review the clinical and radiologic features and interventional treatment of GI fistulae.

A Rural Dementia-Friendly Village Project and Dementia Awareness, Cognition, and Depressive Symptom : A Preliminary Study

OBJECTIVE: According to the 3rd Korean National Dementia Plan, the dementia-friendly community initiative was launched. The aim of this study was to evaluate the effects of a rural dementia-friendly village project on the participants. METHODS: Jeollabukdo Provincial Dementia Center designated Sosu-maeul, located in Buan-gun Jeollabuk-do, as a rural dementia-friendly village. We conducted dementia partnership education, youth-elder matching activity, and cognitive enhancing program. The efficacy of this project was evaluated by the changes in dementia awareness, cognitive function, and depressive symptoms. We used dementia awareness questionnaire, Mini-Mental Status Examination for Dementia Screening (MMSE-DS), and Korean version of Short form of Geriatric Depression Scale (SGDS-K). RESULTS: This study was carried out with 24 residents in this community. There was no significant change in dementia awareness score between pre- and post-intervention (p=0.25). MMSE-DS score was significantly increased from 24.5 to 25.5 (p < 0.001) and SGDS-K score was statistically improved from 3.5 to 2.5 (p=0.04) after interventions. CONCLUSION: We Jeollabukdo Provincial Dementia Center carried out a pilot study of a rural dementia-friendly village project. This project led to improvements on cognitive functions and depressive symptoms in the participants. But the improvement of dementia awareness was not achieved. More direct and experiencing interventions for people with dementia are necessary to improve dementia awareness.

The Influence of Hearing Ability of Ordinary People on the Quality of Life / 보건행정학회지

BACKGROUND: In this research, we conducted an analysis to grasp the relationship between hearing and quality of life and to prepare effective troubleshooting. METHODS: In this study, we analyzed using the data of the 6th term of the National Health and Nutrition Survey of the Disease Management Headquarters. And, out of 7,380 people, 3,598 adults over the age of 40 years who participated in the hearing test were selected as final research subjects and analyzed. RESULTS: It was confirmed that the result of the analysis affects the quality of life based on hearing. The quality of life associated with hearing loss was unpleasant, motor ability, anxiety/depression, and everyday life affected in order of self management. And factors having an effect on the quality of life of the study subjects were found to be gender, elderly, unmarried, low hearing, low household income, absence of economic activity, and low teaching standards. CONCLUSION: The conclusion is that strengthening education for realistic management and prevention rather than treatment for unconditional hearing impairment will overcome low self esteem and loneliness and alleviate any uncomfortable life that people with hearing loss give. It is expected to be possible.

Interleukin-13 Increases Podocyte Apoptosis in Cultured Human Podocytes

PURPOSE: Podocytes are important architectures that maintain the crucial roles of glomerular filtration barrier functions. Despite this structural importance, however, the mechanisms of the changes in podocytes that can be an important pathogenesis of minimal change nephrotic syndrome (MCNS) are not clear yet. The aim of this study was to investigate whether apoptosis is induced by interleukin (IL)-13 in cultured human podocytes. METHODS: Human podocytes were treated with different IL-13 doses and apoptotic cells were analyzed using terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL assay) and fluorescence-activated cell sorting (FACS). RESULTS: The IL-13 increased the number of TUNEL-positive cells in a dose-dependent manner at 6 and 18 hours (P<0.05 and P<0.05, respectively). The apoptosis rate was appeared to be increased slightly in the IL-13-stimulated podocytes (8.63%, 13.02%, and 14.46%; 3, 10 and 30 ng/mL, respectively) than in the control cells (7.66%) at 12 hours by FACS assay. CONCLUSION: Our study revealed that IL-13 expression may increase podocyte apoptosis. Blocking the IL-13 signal pathway can potentially play an important role in regulating the apoptosis of podocytes.

Successful treatment of tubulointerstitial nephritis and uveitis with steroid and azathioprine in a 12-year-old boy / 소아과

Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease, often underdiagnosed or misdiagnosed in children. We describe the case of a 12-year-old boy who presented to Severance Hospital with a 1-month history of bilateral conjunctival injection. He was first evaluated by an Ophthalmologist in another hospital and diagnosed with panuveitis. Laboratory tests indicated renal failure, and a renal biopsy confirmed the diagnosis of acute tubulointerstitial nephritis. An extensive exclusion of all possible causes allowed a diagnosis of TINU syndrome. The patient was treated with a systemic corticosteroid (initially prednisolone, 2 mg/kg and later deflazacort 1 mg/kg) and topical steroid drops for 1 month. Azathioprine was later added to the treatment regimen and the systemic steroid was slowly tapered. The final outcome of renal-ocular disease was favorable in the patient. However, long-term follow-up is necessary to properly manage frequent relapses and incomplete renal recovery. TINU should be considered as a differential diagnosis in children with uveitis or acute renal failure.

Abdominal Wall Hematoma as a Rare Complication following Percutaneous Coronary Intervention

Abdominal wall hematoma is a rare but potentially serious vascular complication that may develop after coronary angiographic procedures. In particular, an oblique muscle hematoma caused by an injury of the circumflex iliac artery is very rare, yet can be managed by conservative treatment including hydration and transfusion. However, when active bleeding continues, angiographic embolization or surgery might be needed. In this study, we report an uncommon case of injury to the circumflex iliac artery by an inappropriate introduction of the hydrophilic guidewire during the performance of a percutaneous coronary intervention.

Hyponatremia May Reflect Severe Inflammation in Children with Kawasaki Disease

PURPOSE: The aim of the present study was to investigate the risk factors for the development of coronary artery lesions (CALs) and to determine whether hyponatremia is associated with CALs in children with Kawasaki disease (KD). METHODS: We retrospectively analyzed the data of 105 children with KD who were admitted to Ilsan Hospital between January 2000 and July 2011. RESULTS: Erythrocyte sedimentation rate (P = 0.013), total bilirubin levels (P = 0.017) were higher and serum sodium levels (P = 0.027) were lower in KD children with CALs than those without. White blood cell (WBC) counts (P = 0.006), neutrophil counts (P = 0.003) were higher and albumin levels (P = 0.009) were lower in KD children with hyponatremia than those without. On multiple logistic regression analysis, hyponatremia (P = 0.024) and intravenous immunoglobulin??resistance (P = 0.024) were independent risk factors for CALs in KD. Furthermore, serum sodium levels were correlated negatively with WBC counts (P = 0.004), neutrophil counts (P < 0.001), total bilirubin levels (P = 0.005) and positively with albumin levels (P = 0.009). CONCLUSION: Our study indicates that hyponatremia may reflect severe inflammation in children with KD.

Outcomes of Hemodialysis in Children: A 35-Year Experience at Severance Hospital

PURPOSE: The aim of this study was to analyze the results of children treated with hemodialysis (HD) at Severance Hospital over 35 years in terms of incidence, etiologies, characteristics, complications, and clinical outcomes. MATERIALS AND METHODS: We analyzed 46 children admitted to Severance Hospital who had undergone HD between January 1979 and December 2013. RESULTS: The main etiologies of the 23 end-stage renal disease (ESRD) patients who had received HD were chronic glomerulonephritis (7 patients, 30.4%) and congenital anomalies of the kidney and urinary tract (7 patients, 30.4%), whereas the etiology of the 23 acute kidney injury (AKI) patients was hemolytic uremic syndrome (6 patients, 26.1%). Compared with ESRD patients, hemocatheter placement in the femoral vein was preferred over the subclavian or internal jugular vein in the AKI patients (p=0.012). The most common complication was catheter related complication (10 patients, 21.7%). The site of hemocatheter insertion was not related to the frequency of oozing. Placing the hemocatheter in the femoral vein resulted in significantly more events of catheter obstruction than insertion in the internal jugular vein or the subclavian vein (p=0.001). Disequilibrium syndrome occurred more frequently in older patients (p=0.004), as well as patients with a greater body weight (p=0.008) and a higher systolic and diastolic blood pressure before HD (systolic: p=0.021; diastolic: p=0.040). CONCLUSION: Based on the 35 years of experience in our center, HD can be sufficiently and safely carried out even in children without significant complications.

Regulation of Stem Cell Fate by ROS-mediated Alteration of Metabolism

Stem cells have attracted much attention due to their distinct features that support infinite self-renewal and differentiation into the cellular derivatives of three lineages. Recent studies have suggested that many stem cells both embryonic and adult stem cells reside in a specialized niche defined by hypoxic condition. In this respect, distinguishing functional differences arising from the oxygen concentration is important in understanding the nature of stem cells and in controlling stem cell fate for therapeutic purposes. ROS act as cellular signaling molecules involved in the propagation of signaling and the translation of environmental cues into cellular responses to maintain cellular homeostasis, which is mediated by the coordination of various cellular processes, and to adapt cellular activity to available bioenergetic sources. Thus, in this review, we describe the physiological role of ROS in stem cell fate and its effect on the metabolic regulation of stem cells.

Noninfectious Complications of Peritoneal Dialysis in Korean Children: A 26-Year Single-Center Study

PURPOSE: The aim of this study was to investigate noninfectious complications of peritoneal dialysis (PD), including mechanical and metabolic complications, at a single center in Korea. MATERIALS AND METHODS: We analyzed data from 60 PD patients aged < or =18 years (40 boys and 20 girls) during the period between 1986 and 2012. The collected data included gender, age, causes of PD, incidence of noninfectious complications, and treatment for the complications. RESULTS: The mean duration of PD therapy was 28.7+/-42.1 months (range 1-240 months). The most common cause of end-stage renal disease was glomerular disease (43.3%). There were no statistically significant differences between patients with and without mechanical complications regarding gender, age at the start of PD, and total duration of PD. Outflow failure was the most common catheter-related complication (14.3%), followed by leakage (10.0%) and hernia (8.6%). Metabolic complications, such as hyperglycemia and hypokalemia, were observed in three of 16 patients. The frequency of noninfectious complications of PD in our study was comparable with those in previous pediatric studies. PD was switched to hemodialysis (HD) in only three patients. CONCLUSION: Our results indicate that noninfectious complications of PD are common, though they hardly lead to catheter removal or HD in pediatric patients on PD.

Current Status and Progress of Telemedicine in Korea and Other Countries / 대한의료정보학회지

OBJECTIVES: The purpose of this study was to review the current telemedicine of the Korea and the telemedicine of the other countries. METHODS: This study reviewed several documents on telemedicine and summarized the documents on the initiation of the telemedicine of the Korea, the recent regulations of the government, the analytical research results, and the telemedicine of foreign countries. RESULTS: One of recent demonstration trials of telemedicine began in July 2015 in the Korea. The plan was to conduct an emergency telemedical treatment trial among the cooperative medical service centers until the end of February 2016. No telemedical services were provided at the level of local primary care clinics, and there was 1.2% provision at the hospital level. The Europe Union and the United States had more active telemedical services in comparison to the Korea. CONCLUSIONS: The introduction and usage of telemedicine in the Korea was behind those of other countries. It is necessary to develop a proactive support policy for telemedicine through a government implemented trial.

Relationship of age at menarche on anthropometric index and menstrual irregularity in late adolescent girls in Seoul

PURPOSE: To examine the relationship between menarcheal age and anthropometric indices and menstrual irregularity in late adolescent girls in Seoul. METHODS: We surveyed 4,218 fertile adolescent girls between the ages of 16 and 18 years to determine their anthropometric indices and menarcheal age. Measurements were taken from June 2008 to October 2009 at seven girl's high schools in Seoul, Korea. Participants were offered self-report questionnaire as a survey tool that included questions on anthropometric indices (height, weight, waist circumference), menarcheal age, menstrual pattern, frequency of menstruation per year. RESULTS: The participants were categorized into three groups based on menarcheal age: early menarche group (younger than 2 standard deviations [SD]), mid menarche group (within +/-2 SD), late menarche group (older than 2 SD). The mean age of early menarche group was 9.9+/-0.2 years, mid menarche group 12.5+/-0.9 years, late menarche group 15.1+/-0.3 years (P < 0.001). Heights were recorded as 160.4+/-5.2 cm, 161.8+/-4.9 cm, 162.3+/-4.7 cm in early, mid, and late menarche group, respectively (P = 0.001). Body mass index (BMI) and waist circumference significantly were lager in early menarche group than mid and late menarche ones (P < 0.001). The menarcheal age had a positive correlation with height and negative correlations with weight, BMI, waist circumference (P < 0.001). The prevalence of oligomenorrhea was more frequent in late menarche group than early and mid menarche group. CONCLUSION: The menarcheal age have positive relationship with height and inverse relationship with BMI and waist circumference in late adolescent girls in Seoul. Late menarcheal girls are disposed to have menstrual irregularity compared to early menarcheal girls.

A Case of Atypical Thrombotic Microangiopathy

We report the case of a 14-year-old girl, diagnosed with atypical thrombotic microangiopathy (TMA). The patient presented with persistent fever, nausea, and newly developed peripheral edema. Her laboratory findings indicated chronic anemia with no evidence of hemolysis, thrombocytopenia, or elevated serum creatinine level. A few days after hospitalization, acute renal failure and fever worsened, and proteinuria developed. On day 40 of hospitalization, she experienced a generalized tonic seizure for 5 min, accompanied by renal hypertension. Brain magnetic resonance imaging revealed posterior reversible leukoencephalopathy syndrome. After steroid pulse therapy, a renal biopsy was performed because of delayed recovery from thrombocytopenia. The biopsy findings showed features of thrombotic microangiopathic hemolysis with fibrinoid change restricted. Current diagnostic criteria for TMA have focused on thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, and diagnosis is based on the clinical presentation and etiology, with the consequence that idiopathic and atypical forms of TMA can be overlooked. Developing effective tools to diagnose TMA, such as studying levels of ADAMTS13 or testing for abnormalities in the complement system, will be the first step to improving patient outcomes.

Renal Manifestations and Imaging Studies of Kawasaki Disease

PURPOSE: The aim of this study was to verify renal inflammation following Kawasaki disease (KD) using single photon emission computed tomography along with Technetium-99m dimercaptosuccinic acid scintigraphy (DMSA renal SPECT). METHODS: From March 2011 to October 2011, 15 patients diagnosed with KD at the National Health Insurance System Ilsan Hospital were enrolled in the study. All patients underwent DMSA renal SPECT to evaluate renal involvement during the acute phase of KD. Urine beta2-microglobulin (beta2-MG), a marker of renal proximal tubular dysfunction, was also measured to assess renal damage. RESULTS: All 15 patients had normal renal function test results. However, microscopic hematuria and pyuria were observed in 13% and 33% of the patients, respectively. Moreover, urine beta2-MG was elevated in 46% of the patients. In addition, patients were divided into two groups based on beta2-MG level: those with an increased beta2-MG level, and those with a normal beta2-MG level. No significant differences were found between these two groups in clinical characteristics, laboratory, sonography, and echocardiography findings. All patients' DMSA renal SPECT scans were normal. CONCLUSION: Our study showed that mild abnormalities in the urinalysis and elevated urine beta2-MG were the only findings of renal involvement in KD. However, no aggressive renal manifestations were detected on DMSA renal SPECT.

A Comparison between Simple Fractionation and Hyperfractionation in Advanced Cervical Cancer: Tumor Control and Radiation Complications / 고신대학교의과대학학술지

OBJECTIVES: To discern in advanced uterine cervical cancer whether the hyperfractionation is more effective in tumor control and in reducing radiation complication rates than the simple fractionation. METHODS: We retrospectively reviewed the medical records of 184 patients with advanced cervical cancer at our hospitals from January 2000 to December 2004. All patients were treated with radiation, 114 patients with simple fractionation, and 70 patients with hyperfractionation. RESULTS: Mean age was 55.4 years at baseline study. Complications were occurred in 90 patients of the 184 patients who treated with radiation therapy. Of these, 48 patients suffered from gastrointestinal complications, 24 patients suffered from genitourinary complications and 18 patients had both complications. Complications were occurred in 72 cases in simple fractionation group and 40 cases in hyperfractionation group. 77 patients had acute complications and 13 patients had chronic complications. There was no statistically significant difference between two groups (P = 0.772). Mild complication were occurred in 75 patients and severe complication were occurred in 15 patients, there was no statistically significant difference in two groups (P = 0.495). 66 patients had gastrointestinal complications and 42 patients had genitourinary complications, there was no statistical significance in two groups (P = 0.910). CONCLUSION: Many complications were occurred in patients who treated with radiation therapy, but there was no statistically significant survival and complication difference in two groups. Further research is needed.

Gluteal and Thigh Compartment Syndrome due to Rhabdomyolysis Following Prolonged Immobilization: A Case Report / 대한신장학회지

Compartment syndrome is rarely associated with non-traumatic rhabdomyolysis. We report the case of a 23-year-old man who developed compartment syndrome associated with rhabdomyolysis caused by prolonged immobilization after antidepressive drug overdose. Elevation of serum creatine phosphokinase and myoglobinuria indicated rhabdomyolysis. Painful swelling of the right buttock and thigh and right lower limb paralysis with sensory and motor deficit were suggestive of gluteal and thigh compartment syndrome with the complication of sciatic nerve injury. The patient received an immediate fasciotomy, medical treatment and rehabilitation. At five months after initial treatment, the patient could walk independently with nearly full recovery of his right lower limb function.

Serum C-Reactive Protein Levels in Normal-Weight Polycystic Ovary Syndrome

BACKGROUND/AIMS: Serum levels of highly sensitive C-reactive protein (hsCRP), a vascular inflammatory marker, may predict the development of cardiovascular disease (CVD) and type 2 diabetes. Women with polycystic ovary syndrome (PCOS) are at greater risk for type 2 diabetes and CVD. The aim of this study was to compare hsCRP levels between normal weight women with PCOS and controls with a normal menstrual cycle and to determine the factors associated with serum hsCRP levels. METHODS: Thirty-nine lean PCOS patients and 24 healthy, regular cycling women were enrolled in this study. We performed anthropometric measurements, fat computed tomography (CT), and blood sampling to determine blood chemistry and levels of hsCRP, gonadotropins, testosterone, and sex-hormone binding globulin. We also conducted 75-g oral glucose-tolerance test and euglycemic hyperinsulinemic clamp to assess insulin sensitivity. RESULTS: Serum hsCRP concentrations were higher in women with PCOS than in women with regular mensturation. However, this difference was no longer significant after adjusting for body mass index (BMI). hsCRP levels were correlated with waist circumference (r=0.46, p<0.01), BMI (r=0.46, p<0.01), visceral fat area (r=0.45, p<0.01), and systolic (r=0.42, p<0.05) and diastolic blood pressure (r=0.39, p<0.05). hsCRP also tended to be negatively associated with insulin-mediated glucose uptake (IMGU) (r=-0.31, p=0.07). A multiple regression analysis revealed that BMI (beta=0.29, p<0.05), systolic blood pressure (beta=0.39, p<0.01), and IMGU (beta=-0.31, p<0.05) predicted serum hsCRP levels in women with PCOS. CONCLUSIONS: PCOS by itself does not seem to be associated with increased hsCRP levels, whereas known CVD risk factors affect serum hsCRP levels in PCOS.

A Case of Pulmonary Hemorrhage Associated with Henoch-Schonlein Purpura / 결핵및호흡기질환

Henoch-Schonlein purpura (HSP) is an immunologically mediated systemic vasculitis of small blood vessels that primarily involves the skin, gastrointestinal tract, joints and kidneys. HSP is a common vasculitic syndrome in children who, in most cases, achieve complete recovery. Pulmonary hemorrhage is a very rare manifestation of HSP. The authors present a case of a 46-year-old male presenting with pulmonary hemorrhage and renal involvement and the diagnosis of HSP. The patient responded to prednisolone therapy.
