Development of the Korean Version of the Social Functioning Scale in the Schizophrenics : A Study on the Reliability and Validity

Objectives : The purpose of this study was to develop the Korean version of the Social Functioning Scale (KSFS) in the patients with schizophrenia. METHODS : KSFS was administered to 90 schizophrenic patients and 80 their parents and 90 normal controls for examining the reliability and validity. RESULTS : Data analysis showed statistically significant reliabilities and validities of KSFS. The test-retest reliability, rater vs. self-report reliability, and internal consistency for total scores of KSFS were 0.93, 0.44 and 0.94 respectively. Evidence for discriminant validity of KSFS comes from the results that the mean scores of schizophrenic patients were significantly higher than those of normal controls. Construct validity was assessed by calculating the 7 inter-areas correlations of the KSFS, and all areas were statistically significant. Significant correlations between the total scores of KSFS and those of SOFAS lend support for the concurrent validity of this instrument. Factor analyses were performed and two factors were extracted accounting for 63.7% of the variance. Sensitivity was assessed indirectly via the distribution and range of scores on the SFS. The normal control group showed a distribution around a higher mean with a moderate positive skew. CONCLUSION : KSFS was found to be a valid, reliable, and sensitive instrument which can be used to evaluate the degree of social functioning in the patients with schizophrenia.

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 Pilot Study of Postoperative Delirium in Spine Surgery

OBJECTIVES: Delirium is a common postoperative complication in old adults associated with adverse events including functional decline, longer lengths of stay, and risk of institutionalization. The purpose of this study is to evaluate the incidence, preoperative, intraoperative, and postoperative risk factors of postoperative delirium in spine surgery. METHODS: Seventy-nine patients who underwent spine surgery were included. Preoperative assessments included current medical illness, number of comorbid problems, and the number of medications by past medical history, medical record, and interview with patients and caregivers. Intraoperative risk factors were evaluated. Laboratory data were checked preoperatively and postoperatively. The presence of delirium was determined by the Korean version of Delirium Rating Scale (K-DRS). RESULTS: Postoperative delirium was found in patients (7.6%). There was an association suggested between older age and postoperative delirium in spine surgery (p<0.05). An association was suggested between increasing numbers of medical conditions and postoperative delirium (p<0.05). Preoperative hemoglobin, hematocrit, sodium, potassium, calcium, albumin levels and postoperative hemoglobin and total protein levels were in the delirium group was significantly lower than those in control group (p<0.05). CONCLSION: This study showed that the postoperative delirium in spine surgery is not rare and several preoperative and postoperative factors are involved in the development of delirium. This pilot study is the first prospective trial in the area of postoperative delirium in spine surgery with a small sample size and short-term period, so further research with large sample size will be necessary.

Isolated spontaneous chylopericardium during the treatment of non-Hodgkin's lymphoma / 대한내과학회지

Although malignant pericardial effusion is a common complication of malignancy, chylopericardium is a rare entity characterized by the accumulation of chylous fluid in the pericardial sac. The lymphatic vessels of the pericardium drain into the thoracic duct. The mechanical obstruction of venous drainage plays an important role in the pathophysiology of this disease. In most cases, pericardiocenthesis is needed to prevent cardiac tamponade. We present a case of a 15-year-old boy diagnosed as non-Hodgkin's lymphoma, diffuse large B cell, with superior vena cava syndrome, who developed an isolated chylopericardium after the first cycle of chemotherapy. We confirmed the diagnosis with an echocardiography, lymphangiography, and fluid analysis. Chylopericardium was managed successfully with pericardiocenthesis and drainage. If pericardial effusion were developed during the treatment of non-Hodgkin's lymphoma, chylopericardium should be considered as one of the differential diagnoses and associated venous thrombosis around the thoracic duct outlet should be ruled out.

The Effect on Onset Time of Warming Local Anesthetic for Caudal Block / 대한마취과학회지

BACKGROUND: One of the main disadvantages of caudal block is the long latent period before a satisfactory blockade is obtained. Many investigators have used various preparations of local anesthetic solutions to improve the speed of onset. This study was performed to evaluate the effectiveness of prewarming of lidocaine HCl for caudal block. METHODS: Fifty healthy young patients (ASA I) were allocated into two groups, A and B. In group A, the local anesthetic solution were injected at room temperature (25 degrees C), while in group B, they were injected at 37oC. All the caudal block were performed using 2% lidocaine HCl 20 ml with fentanyl 100ug and epinephrine 1:200,000. The onset time was defined as the period from completion of injection until the patient first noticed loss of sensation to pin-prick on perianal region. Assessment of sensory loss was made at 15 seconds interval. We have compared the onset of sensory blockade between groups. The duration of analgesia and any significant side effects were also recorded. RESULTS: The onset of sensory blockade was significantly faster in group B (3.5 +/- 0.5 minutes) than group A (6.2 +/- 0.9 minutes). The duration of analgesia were not significantly changed between groups. Side effects of urinary retention, pruritus and nausea were noted between both groups but the difference was not significant. CONCLUSIONS: We have found that the onset time was 44% faster with warm lidocaine-fentanyl mixture (37 degrees C) than with the room temperature (25 degrees C). The improved clinical usefulness was achieved with no increase in side effects. The technique is a safe and effective method to reduce the latency of onset.
