OBJECTIVES: This study was conducted to investigate the effectiveness of a class-based school violence prevention program for elementary school student. METHODS: 29 students were assigned to the school violence prevention program of 8 sessions, 28 students have been assigned to the control group. We assessed participants at baseline and post-intervention, through their self-report questionnaires such as Children's Depression Inventory (CDI), Strengths and Difficulties Questionnaire and school violence experience, awareness about school violence, and coping ability to school violence. We compared the baseline and post-intervention result of each group and compared the post-test scores between the intervention group and the control group. RESULTS: Comparing the intervention group and the control group, the post-intervention CDI total score and the awareness about school violence showed significant improvement in the intervention group. When compared according to gender, male students' perception of school violence was improved, and female students showed significant differences in CDI scores. CONCLUSION: The CDI total scores and the perception of school violence were improved in the intervention group compared to the control group. And there are differential pattern of intervention effects according to gender. These findings have important implications to develop effective violence prevention programs.

BACKGROUND: The sniffing position is recommended for conventional laryngeal mask airway (LMA) insertion. However, there has been a high success rate of LMA insertion with the head in the neutral position. The effect of a difficult airway on the ease of LMA insertion is not clear. In this study, we compared the ease of LMA ProSeal(TM) (PLMA) insertion and the fiberoptic scoring according to the head position and the presence of a difficult airway. METHODS: After obtaining informed consent from the subjects, we enrolled 144 adult patients (age range: 18-65) with an ASA physical status 1 or 2. After evaluation of the airway, all the patients were grouped into the EA (easy airway) group (n = 68) and the DA (difficult airway) group (n = 76). According to the head position, each group was divided into the EA-SE (extension) group (n = 35), the EA-SN (sniffing) group (n = 33), the DA-SE group (n = 39) and the DA-SN group (n = 37). The success rate and insertion time at the first attempt were evaluated. The position of the PLMA was fiberoptically scored from the mask aperture of the airway tube in the original head position. After the head position was changed to the sniffing and neutral positions in the SE and SN group, respectively, the position of PLMA was re-evaluated fiberoptically. RESULTS: The success rate and insertion time at the first attempt and the fiberoptic score showed no significant difference among the groups. After head position was changed, there were no significant changes in the fiberopitc scores. CONCLUSIONS: A difficult airway and the head position had no influence on the ease of PLMA insertion and the fiberopic score. Therefore, the head position can be selected according to the individual patient's situation.

Tetrachloroethylene is widely used as a solvent for degreasing operations and for dry cleaning. Accidental overexposure of tetrachloroethylene produces central nervous system depression which may be followed by hepatic and renal damage. Renal changes are usually mild and reversible with removal of the offending agent. The relationship between exposure to tetrachloroethylene and chronic renal failure remains controversial. Acute or subacute tetrachloroethylene poisoning has been occasionally observed in dry cleaners and fatal cases have been rarely reported. We experienced a case of acute tetrachloroethylene poisoning complicated by acute renal failure. After ingestion of 200 mL tetrachloroethylene, a 32- year-old man was admitted to the clinic in semicoma. Under the conservative treatment, the clinical condition of the patient improved consideravely, but acute renal failure developed. After 5 times hemodialysis during the admission, he recovered completely from acute renal failure.

Even though it is a rare complication to have hepatic cyst infection in adult polycystic kidney disease, the patient is expected to be complicated with sepsis or acute cholangitis and die if not treated properly. The typical clinical manifestations of hepatic cyst infection are fever and right upper quadrant abdominal pain. Liver enzyme and serum bilirubin levels may be elevated. The clinical outcome of hepatic cyst infection is better when antibiotic and drainage are performed simultaneously than only antibiotic is used. We experienced a case of infected hepatic cyst from a 58-year-old male patient receiving hemodialysis with autosomal dominant polycystic kidney disease. Due to his persistent fever and leukocytosis during intravenous antibiotic therapy, we performed percutaneous drainage of hepatic cyst. Because the drainage fluid presented leukocytosis and deep yellow color, we diagnosed the case as a hepatic cyst infection. We applied both percutaneous drainage of infected liver cyst and antibiotic and we observed clinical improvement.

Infective endocarditis related to pacemaker implantation is a rare complication. However, it is a potentially lethal complication with a mortality rate of 30 to 35%. Infective endocarditis associated with pacemaker implantation usually involves the right heart and tricuspid valve. Conservative treatment without complete removal of the entire pacing system is prone to fail (i.e. result in infection relapse or development of sepsis). Therefore, the total extraction of the entire pacemaker system should be considered as standard therapy for most patients with pacemaker-related endocarditis and for many patients with local infectious symptoms at the site of pacemaker implantation to achieve complete recovery. We report a case of a 42-year-old man with documented pacemaker related left-sided endocarditis that was associated with multiple embolic events. Also, we review the literature regarding pacemaker-related endocarditis and local wound infection, in particular with respect to the modalities of treatment.

BACKGROUND: This study constructed a partial-least-square path-modeling (PLS-PM) model and found the pathway by which the postsurgical vertical dimension (VD) affects the extent of the final mandibular setback on the B point at the posttreatment stage for the skeletal class III surgery-first approach (SFA). METHODS: This study re-analyzed the data from the retrospective study by Lee et al. on 40 patients with skeletal class III bimaxillary SFA. Variables were obtained from cone beam computed tomography (CBCT)-generated cephalograms. Authors investigated all variables at each time point to build a PLS-PM model to verify the effect of the VD on the final setback of the mandible. RESULTS: From PLS-PM, an increase in VD10 was found to decrease the absolute value of the final setback amount of the mandible, which reflects the postsurgical physiological responses to both surgery and orthodontic treatment, which, in turn, can be interpreted as an increase in postoperative mandibular changes. CONCLUSIONS: To resolve the issue of collinear cephalometric data, the present study adopted PLS-PM to assess the orthodontic treatment. From PLS-PM, it was able to summarize the effect of increased postsurgery occlusal vertical dimension on the increased changeability of the B point position at the posttreatment stage.

Osmotic demyelination syndrome (ODS) is a distinctive clinical syndrome with characteristic MR features in the central pons (central pontine myelinolysis) and in other brain locations (extrapontine myelinolysis). Rapid correction of hyponatremia is associated with ODS, but hyperosmolality rarely causes it. Here we report a case of ODS developed in a hemodialysis patient with severe uremia and concomitant hyperosmolality. A 67-year-old male was presented with general weakness and dyspnea. Laboratory findings showed severe uremia (blood urea nitrogen, 167 mg/dL; serum creatinine, 15 mg/dL), hyperosmolality (336 mOsm/kg H2O), and normal range of sodium (145 mEq/L). After the first hemodialysis treatment, his consciousness was changed to lethargic state. We initially suspected dialysis disequilibrium syndrome, but the symptoms were aggravated. MRI showed edema in central pons and symmetrical extrapotine lesions in the subcortical white matter, lateral thalamus, and posterior capsule, consistent with ODS. In spite of aggressive measures including continuous renal replacement therapy, he died of sepsis at the 26th hospital day.

BACKGROUND: Previous studies have reported that fasting insulin and blood glucose levels are higher in postmenopausal than in premenopausal women and that insulin resistance was more serious in postmenopausal women. The effects of menopause on glucose metabolism have been well studied, but it is unclear whether age at menopause onset is associated with fasting blood sugar and HbA1c levels. The purpose of this study is to determine the effect of menopause age on diabetes and prediabetes.METHODS: We retrospectively analyzed data from the Sixth Korea National Health and Nutrition Examination Survey (2013–2015). The participants were 2,156 naturally menopausal women, except diabetes, stroke, coronary artery disease and cancer patients. The study population was divided into four groups according to the age of natural menopause onset ( < 40, 40–44, 45–55, and ≥56 years). Diagnosis of diabetes and prediabetes was based on the American Diabetes Association guideline. The association between menopause age and diabetes or prediabetes was analyzed by multiple logistic regression.RESULTS: Women reaching menopause at 40–44 years were 4.901 times more likely to have diabetes (odds ratio [OR], 4.901; 95% confidence interval [95% CI], 1.353–17.756, P=0.016) than those who reached menopause at an age of ≥56 years. Women with menopause at age < 40 years were 2.839 times more likely to have diabetes or prediabetes (OR, 2.839; 95% CI, 1.012–7.968, P=0.047).CONCLUSION: Women with premature menopause (< 40 years) have high risk of developing diabetes or prediabetes, and women with a menopause age of 40–44 years have high risk of developing diabetes.

BACKGROUND: Several studies have evaluated risk factors for falls; however, the risk factors for recurrent falls are poorly understood. Therefore, this study evaluated the prevalence and factors associated with recurrent falls.METHODS: This study included 250 patients aged over 65 years, all of whom visited the emergency department (ED) at Seoul Medical Center following a fall from January 2016 to December 2017. We reviewed the patients' medical records for demographic data and medical history. Previous fall history, use of gait-aids, residence type, and fall recurrence were assessed via individual telephone calls.RESULTS: During the follow-up period, 21.6% (n=54) of the 250 subjects experienced recurrent falls. Logistic regression analyses showed that fall recurrence was significantly associated with a previous fall history and the residence type. Subjects who lived in basement-level residences had a significantly higher risk of fall recurrence compared to those who lived in ground-level residences (odds ratio, 8.910; 95% confidence interval, 1.082–73.366).CONCLUSION: This study revealed a high incidence of fall recurrence in older adults who visited the ED due to falls. Our results suggest that careful evaluation and intervention are essential, especially in elderly individuals with fall histories and those who live in residences associated with ncreased risk of falls.
