OBJECTIVES: Sleep problems has been consistently reported as a suicidal risk factor in adults and, recently, also in adolescents. In this study, dividing study subjects by the previous suicidal behaviors (suicidal vs non-suicidal), we compared the group differences of suicidal risk factors, and examined the possibility of sleep as a suicidal risk factor. METHODS: Study subjects were 561 (271 boys and 290 girls) from a community sample of high school students. Suicidal Risk Behavior Checklist, Center for Epidemiological Study-Depression (CES-D), Symptom Checklist-90-Revision (SCL-90-R) Anxiety and Aggression subscale, Pittsburg Sleep Quality Index (PSQI) were done. RESULTS: Forty six students (8.1%) reported previous actual self-harm behavior as a suicidal attempt, 181 students (32.4%) reported having suicidal thought only. Three hundred thirty four students (59.5%) reported no previous suicidal behavior (thought and attempt, both). Suicidal behavior group showed higher score on risk behaviors such as school violence, substance use and internet addiction. CES-D, SCL-90-R, PSQI showed significant group difference. Logistic regression analysis showed suicidal risk were significantly associated with depression, stress in suicidal risk factors and sleep latency, daytime dysfunction in PSQI. Analysis of variance (ANOVA) shows the most prolonged sleep latency and increased index of all PSQI components except sleep efficiency in suicidal attempt group. CONCLUSIONS: Sleep Problems had a strong association with the suicidal risk behavior in adolescents. Sleep problems, especially, prolonged sleep latency, daytime dysfunction might be important markers for suicidal behavior. Screening for sleep problems in adolescents are encouraged for the parents, school teachers, and related medical physicians.

Relapsing polychondritis is a rare inflammatory disorder affecting the cartilaginous structures throughout the body. Although there is no pathognomonic laboratory tests, clinical features, when coupled with histopathologic findings, enable one to make a diagnosis of relapsing polychondritis. A 26-year-old man presented with purplish, swollen, and tender auricles and injected eyes. His symptoms had developed eight months ago and fluctuated irrespective of various medications such as corticosteroids and antibiotics. Histopathologic examination revealed loss of basophilic staining of the cartilage with some dissolution of its structures. Treatment was initiated with dapsone, However, the remission was too immediate to be considered as a effect of dapsone.

OBJECTIVES: Hemodynamic measurements of chronic portal hypertension were done to study the mechanisms that maintain high portal pressure despite well developed collateral circulations. METHODS: A prehepatic portal hypertensive rat model was produced by partial portal vein ligation. Cardiac output, organ blood flow and porto-systemic shunt were measured by radioisotope labeled microsphere methods, and vascular resistance was calculated by standard equation. RESULTS: There was a significant reduction in the weight of the liver and increase in the weight of the spleen in the portal stenotic rats. Porto-systemic shunting, representing development of the collateral circulations, was 96.7+/-0.6% in the portal stenosis group compared with 0.9+/-0.2% in the control group (p<0.01). Portal pressure was significantly increased in the portal stenosis group compared with the control group(12.8+/-1.4 vs. 6.5+/-0.6mmHg; p<0.01). Mean arterial pressure was significantly decreased in portal stenosis group compared with control group(101.4+/-2.5 vs, 129.9+/-3.9mmHg; p<0.01). In the portal stenosis group, cardiac output(135.7+/-8.0 vs. 111.0+/-4.2ml/min; p<0.01) and splanchnic organ blood flow (28.97+/-2.03 vs. 17.90+/-1.27ml/min, p<0.01) were significantly increased, with concomitant decrease in total peripheral vascular resistance(58.0+/-3.3 vs. 88.2+/-4.8 dyne sec/cm5 X 105; p<0.01) and splanchnic vascular resistance(2.54+/-0.20 vs. 5.47+/-0.33 dyne sec/cm5 X 105; p<0.01), However, the portal venous resistance was not significantly different in both groups of rats (3.57+/-0.31 vs. 3.03+/-0.38 dyne sec/cm5 X 105; p>0.05). CONCLUSION: The hemodynamic results of this study indicate that hyperdynamic status of systemic and splanchnic circulation was present in chronic portal hypertension and that the primary factor contributing to the persistently elevated portal venous pressure was the markedly increased portal venous inflow.

PURPOSE: This study was conducted to provide Simulation Problem-Based Learning (S-PBL) for community visit nursing students according to their Myers Briggs Type Indicator (MBTI) personality types for learner-focused education and to verify its effectiveness. METHODS: This study was conducted with subjects having the ST (Sensing-Thinking) and NF (iNtuition-Feeling) personality types, which are conflicting personality types, and forty-one subjects were allocated to the experimental group and nineteen subjects to the control group. The training, provided to subjects once a week, for a total of six times and 100 minutes each time, was with respect to the improvement of problem-solving ability, communication ability, and clinical practice competency. Data were analyzed through t-test and independent t-test. RESULTS: After training, the self-rated problem-solving competency (t=3.07, p=.003), communication ability (t=2.86, p=.006), and academic self-efficacy (t=2.44, p=.018) were significantly higher in the experimental group than in the control group. However, there was not a significant difference in the clinical practice ability rated by subjects themselves (t=1.50, p=.140) and by professors (t=1.08, p=.285), and in the communication ability rated by professors (t=0.72, p=.474). CONCLUSION: The community visit nursing S-PBL, according to MBTI personality types, is a helpful learning method for nursing students participating in self-directed learning of nursing theory and practice.

Between 1989 and 1993, 31 patients who had undergone ACL reconstruction using autogenous patellar bone-tendon-bone were studied to evaluate the effects on knee joint function. After having harvested the central one third of the patellar tendon, it was positioned isometrically through tunnels of tibia and femur and also central defect of the patellar ligament was sutured loosely. Clinically Hospital for special surgery(HSS) knee socre by Marshall 1997, manual knee test, knee extention and flexion angles, Cybex test, KT-2000 measurments and radiological study were performed for subjective and objective symptoms at the average follow-up 33 months (range 18-72 months). Quadriceps weakness of strength less than 80% of the normal side was present in 61% of patients, patellofemoral joint pain in 15%, AP translation more than 3mm in 23%, flexion contracture of 5 degree or more in 29%. Hospital for special surgery(HSS) knee score was improved from 35 to 46 in average during follow-up period. The height of the patella was increased in 2 cases and decreased in 6 cases within normal variation which was not significant statistically. The above results indicate that importance of postoperative rehabilitation program and extension position of knee joint after surgery place a major emphasis on the avoidance of flexion contracture and on the improvement of joint function.

PURPOSE: The aim of this study was to evaluate a ‘patient empowerment program for schizophrenia (PEPS)’ to improve problem solving ability, quality of life, and mental health literacy for hospitalized patients with schizophrenia. METHODS: The study was a non-equivalent control group non-synchronized design. Study participants were recruited from a psychiatric hospital in Republic of Korea. Of 56 participants, 20 were assigned to the experimental group and 36 to the control group. Data were collected from September, 2017 to January, 2018. Data analyses included chi-squared or Fisher's exact tests, t-tests, and repeated measure ANOVA with SPSS/WIN 21.0 program. RESULTS: After participating PEPS, the experimental group showed a significant increase in quality of life and mental health literacy compared to the control group. However, there were no significant differences in problem solving ability between the two groups. CONCLUSION: Findings show that patients with schizophrenia receive benefits from PEPS in terms of quality of life and mental health literacy. However, further research is necessary to develop clinical strategies to improve their problem solving abilities.

Requirement of blood transfusion has been progressively increased and supplements by volunteer donor are not sufficient to their requirements. Moreover homologous blood transfusion are not supplied without risks, espcially the transmission of the serum hepatitis. Twenty procedures, including two total hip replacement arthroplasty, were carried out with acute hemodilutional autotransfusion. The results of this study show that autotransfusion is a safe method without difficulty of blood replacement in elective orthopedic procedures.

Fractures involving joints and about the joints provide complex problems with small comminuted fractures, surrounding soft tissue injuries and articular cartilage damage. Various problems are also encountered on the weight bearing surface, especially on the convex side of the distal Femur. Even though many auther had recommended kinds of management upto now, operative methods are more suggested in order to get good results regarding with the accurate anatomical reduction, rigid internal fixation and early joint motion. The clinical analysis of rnanagements of 20 cases of distai femoral fracture demonstrate that seperate dual incision-bilateral or right angle plane-to originate fracture site, and anatomical reduction & rigid internal fixation, early non-weight bearing ROM exercise of joint were sometimes mandatory to treat the displaced, comminuted fracture.
