Quality of Life and Characteristics of Depression with Subjective Cognitive Decline in Korean Adults :Data from the Seventh Korea National Health and Nutrition Examination Survey / 정신신체의학

Objectives@#：This study aimed to investigate quality of life, severity of depression, suicidality, subjective health and subjective stress of depression with subjective cognitive decline in Korean adults. @*Methods@#：We used the 7th KNHANES data to enroll 415 participants with a score of 10 or higher on Patient Health Questionnaire-9 (PHQ-9), aged 20-64. Depression was divided into two groups based on the presence/absence of subjective cognitive decline. Demographic and psychological characteristics were compared between two groups. Correlation analysis of subjective cognitive decline, quality of life, depression, suicidal idea was car-ried out. To detect which variables influenced quality of life, a multiple regression analysis was carried out. @*Results@#：Among the 415 participants, 98 had depression with subjective cognitive decline. We identified sig-nificant differences in age, marital status, education, employment between the two groups. After adjusting for these variables, depression with subjective cognitive decline had lower EuroQol-5D index scores, more severe depressive symptoms without cognition and worse subjective health than depression without cognitive decline. There was a significant correlation between subjective cognitive decline and quality of life (r=-0.236, p<0.001), suicidal idea (r=0.182, p<0.001), depression score without cognition (r=0.108, p=0.028). Through multiple regression analysis, subjective cognitive decline was predictor of reduced quality of life (β=-0.178, p<0.001). @*Conclusions@#：Depression with subjective cognitive decline has poor quality of life and severe depression. Cognitive decline should be considered to improve treatment result in depression.

The Prevalence of Obesity and Metabolic Syndrome in the Korean Military Compared with the General Population

BACKGROUND: Obesity and related metabolic disorders are growing health challenges worldwide and individuals at military service are not exceptions. The purpose of this study was to examine the prevalence of obesity and metabolic syndrome (MS) in the Korean military and to compare with the general population. METHODS: This was a cross-sectional study of 4,803 young military participants who underwent a corporal health-screening program between October 2013 and October 2014. The National Cholesterol Education Program Adult Treatment Panel III criteria was used to identify MS. We also sampled 1,108 men aged 19–29 years from the Korea National Health and Nutritional Examination Survey from 2010 to 2013 to compare with their military counterparts. RESULTS: The mean age of military participants was 20.8 ± 1.1 years, and 20.6% (n = 988) were obese. The prevalence of MS was 0.8% in military participants, while 7.9% in general population. The risk factors of MS were less prominent among military participants relative to civilians, with the exception of high blood pressure, of which prevalence was higher among military participants (21.5% vs. 18.2%, respectively). In multiple logistic analysis, high physical activity conferred lower odds of MS and obesity in military participants (odds ratios, 0.19 and 0.81, respectively). Age older than 25 years increased risk of most components of MS among civilians. CONCLUSION: The prevalence of obesity and MS is lower in military participants compared with civilians of similar age. Monitoring of high blood pressure and proper stress management are warranted in those at military service.

Clinical Characteristics and Microbiology of Acute Otitis Media of Children: Multicenter Studies / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Acute otitis media (AOM) is one of the most common forms of bacterial infection in children. The aim of this study was to investigate the clinical characteristics and the common pathogens of AOM children who visited three different centers. SUBJECTS AND METHOD: We have conducted a retrospective study of 133 children under 15 years with the diagnosis of AOM that had been seen between January 2010 and January 2011. We examined of AOM children's symptoms, signs and culture results. RESULTS: The most common symptoms were in the order of crying or irritability, otalgia and fever. Otorrhea was significantly higher under 2 years old and drum injection was over 2 years old. The most common pathogens were Streptococcus pneumoniae (26.6%), followed by Moraxella catarrhalis (19.0%), Haemophilus influenzae (11.4%) and Staphylococcus aureus (11.4%). Among the total pathogens, about 71% of pathogens were resistant to amoxicillin, 78% to macroride, and 55.2% to clindamycin. About 58.3% of H. influenza and M. catarrhalis were positive to beta-lactamase. CONCLUSION: More than half of pathogens were resistant to standard dose amoxicillin. For the appropriate treatment of AOM, decisions were made based on the common symptoms, signs and antibiotic resistances of pathogens.

Drug Induced Sleep Endoscopy for Poor-Responder to Uvulopalatopharyngoplasty in Patient with Obstructive Sleep Apnea Patients / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The purpose of this study is to evaluate drug-induced sleep endoscopy (DISE) findings in patients with persistent obstructive sleep apnea (OSA) after uvulopalatopharyngoplasty (UPPP) surgery. SUBJECTS AND METHOD: Patients were included in this study if they had a postoperative DISE evaluation as well as pre- and postoperative polysomnography. DISE findings included the obstructive sites (velum, oropharyngeal lateral walls, tongue base, and epiglottis), and the obstructive patterns of velopharynx (anteroposterior, lateral, and concentric). RESULTS: A total of 77 patients were included in this study. Poor-responder patients to UPPP (n=50) and well-responder patients to UPPP (n=27) were similar with regard to age, gender, body mass index, preoperative AHI, and minimal O2 saturation. In our analysis of DISE findings on poor-responder, velopharynx was the most common obstruction site (100%), followed by oropharynx (88%), tongue base (70%), and epiglottis (44%). Results showed that most patients (n=49) had multiple obstructive sites. No significant differences according to position dependency and REM dependency were found in obstructive sites. However, severe OSA patients had tongue base obstruction more frequently than the moderate OSA patients did. The obstructive pattern of velopharynx usually showed concentric configuration (70%, 35 of 50). CONCLUSION: Our results suggest that the preoperative DISE may be a useful method for determination of the personalized surgery to OSA patients because of its more precise information to upper airway obstruction.

Conversion from Selective to Comprehensive Neck Dissection: Is It Necessary for Occult Nodal Metastasis? 5-Year Observational Study

OBJECTIVES: To compare the therapeutic results between selective neck dissection (SND) and conversion modified radical neck dissection (MRND) for the occult nodal metastasis cases in head and neck squamous cell carcinoma. METHODS: Forty-four cases with occult nodal metastasis were enrolled in this observational cohort study. For twenty-nine cases, SNDs were done and for fifteen cases, as metastatic nodes were found in the operative field, conversion from selective to MRNDs type II were done. Baseline data on primary site, T and N stage, extent of SND, extracapsular spread of occult metastatic node and type of postoperative adjuvant therapy were obtained. We compared locoregional control rate, overall survival rate and disease specific survival rate between two groups. RESULTS: Among the 29 patients who underwent SND, only one patient had a nodal recurrence which occurred in the contralateral undissected neck. On the other hand, among the 15 patients who underwent conversion MRND, two patients had nodal recurrences which occurred in previously undissected neck. According to the Kaplan Meier survival curve, there was no statistically significant difference for locoregional control rate, overall survival rate and disease specific survival rate between two groups (P=0.2719, P=0.7596, and P=0.2405, respectively). CONCLUSION: SND is enough to treat occult nodal metastasis in head and neck squamous cell carcinoma and it is not necessary to convert from SND to comprehensive neck dissection.

Differential Expression of PKD2-Associated Genes in Autosomal Dominant Polycystic Kidney Disease

Autosomal dominant polycystic kidney disease (ADPKD) is characterized by formation of multiple fluid-filled cysts that expand over time and destroy renal architecture. The proteins encoded by the PKD1 and PKD2 genes, mutations in which account for nearly all cases of ADPKD, may help guard against cystogenesis. Previously developed mouse models of PKD1 and PKD2 demonstrated an embryonic lethal phenotype and massive cyst formation in the kidney, indicating that PKD1 and PKD2 probably play important roles during normal renal tubular development. However, their precise role in development and the cellular mechanisms of cyst formation induced by PKD1 and PKD2 mutations are not fully understood. To address this question, we presently created Pkd2 knockout and PKD2 transgenic mouse embryo fibroblasts. We used a mouse oligonucleotide microarray to identify messenger RNAs whose expression was altered by the overexpression of the PKD2 or knockout of the Pkd2. The majority of identified mutations was involved in critical biological processes, such as metabolism, transcription, cell adhesion, cell cycle, and signal transduction. Herein, we confirmed differential expressions of several genes including aquaporin-1, according to different PKD2 expression levels in ADPKD mouse models, through microarray analysis. These data may be helpful in PKD2-related mechanisms of ADPKD pathogenesis.

A case of Hashimoto's encephalopathy presenting with seizures and psychosis / 소아과

Hashimoto's encephalopathy (HE) is a rare, poorly understood, autoimmune disease characterized by symptoms of acute or subacute encephalopathy associated with increased anti-thyroid antibody levels. Here, we report a case of a 14-year-old girl with HE and briefly review the literature. The patient presented with acute mental changes and seizures, but no evidence of infectious encephalitis. In the acute stage, the seizures did not respond to conventional antiepileptic drugs, including valproic acid, phenytoin, and topiramate. The clinical course was complicated by the development of acute psychosis, including bipolar mood, insomnia, agitation, and hallucinations. The diagnosis of HE was supported by positive results for antithyroperoxidase and antithyroglobulin antibodies. Treatment with methylprednisolone was effective; her psychosis improved and the number of seizures decreased. HE is a serious but curable, condition, which might be underdiagnosed if not suspected. Anti-thyroid antibodies must be measured for the diagnosis. HE should be considered in patients with diverse neuropsychiatric manifestations.

Is Hashimoto's Thyroiditis Associated with the Prognostic Factors of Papillary Thyroid Carcinoma? / 대한내분비외과학회지

PURPOSE: In recent studies, the presence of lymphocytic infiltration in patients with papillary thyroid carcinoma (PTC) was reported to be associated with a favorable prognosis. The prognostic significance of Hashimoto's thyroiditis (HT) in patients with PTC remains unclear. The aim of our study was to determine the frequency and prognostic significance of HT in patients with PTC. METHODS: From January 2005 to December 2007, 367 patients who underwent thyroid surgery for PTC were included in this study. They were divided into two groups: Group A (n=71; 19.4%) included the patients diagnosed as having PTC with HT and Group B (n=296; 80.6%) included the patients who had PTC without HT. The clinicopathologic features between Groups A and B were retrospectively reviewed via the medical records. RESULTS: Lymph node metastasis was less frequent in Group A than that in Group B (25.5% versus 41.0%, respectively, P=0.033). However, both groups had similar clinicopathologic features in terms of age, gender, the tumor size, multifocality, extrathyroidal invasion, the TNM stage and the AMES and MACIS scores. Also, the operative method did not differ significantly between the two groups. CONCLUSION: These results suggest that the presence of HT is not associated with the prognostic factors of PTC.

Is Barium Enema Prior to Ileostomy Closure Necessary?

PURPOSE: A barium enema is frequently performed to check for healing prior to ileostomy closure, but there have been reports that ileostomy closure without a contrast study is safe in selected patients. The aim of this study was to assess the necessity of a routine barium enema prior to ileostomy closure. METHODS: Between January 1994 and June 2005, 51 patients with a temporary loop ileostomy who had a barium enema prior to ileostomy closure at Chonbuk National University Hospital were retrospectively reviewed. These patients were divided into 2 groups, the protective ileostomy group and the ileostomy-after-leakage group. To examine the necessity of a routine barium enema prior to ileostomy closure, we assessed whether the barium enema results changed management and whether there were pelvic sepsis and obstructive symptoms following ileostomy closure. RESULTS: In the protective ileostomy group (n=39), the barium enema was performed after a mean of 59 days (range: 27~151 days). There were no abnormal findings at the barium enema, no schedule changes, no pelvic sepsis, and no obstructive symptoms following ileostomy closure. In the ileostomy-after-leakage group (n=12), the barium enema was performed after a mean of 54 days (range: 30~82 days). In 2 patients, with barium enemas at 33 days and 36 days, an anastomotic leakage was found, and ileostomy closure was delayed. CONCLUSIONS: In patients with a protective ileostomy, a barium enema prior to ileostomy closure is unnecessary, but in patients with an ileostomy after leakage, barium enema should be considered.

Perforation of the Hepatic Flexure of Colon by an Ingested Toothbrush

A Foreign body in the gastrointestinal tract is a common clinical problem seen in all age groups and rarely produces symptoms. However, the foreign bodies should be removed if they produce symptoms or remain in the gastrointestinal tract. A 31-year-old man with schizophrenia ingested a 20-cm-sized toothbrush. It passed through the ileocecal valve and penetrated the hepatic flexure of the colon and liver. It was removed successfully by using a surgical procedure. We report this unusual case of colonic perforation by an ingested toothbrush and review the related literature.

Peutz-Jeghers Syndrome with Recurrent Intussusception

The Peutz-Jeghers syndrome is an autosomal dominant hereditary disease characterized by hamartomatous polyps of the gastrointestinal tract and by mucocutaneous melanin deposits. This syndrome is clinically important because of the complication caused by the gastrointestinal polyp, leading to abdominal pain, gastrointestinal bleeding and intussusception. We experienced a case of Peutz-Jeghers syndrome associated with intussusception who was operated due to intussusception 14 years ago.
