PURPOSE: To evaluate the predictability of amount of hemothorax in the patients with blunt chest trauma, supine chest AP radiographs of 66 patients were reviewed and statistically analyzed. MATERIALS AND METHODS: In 66 patients, rib fractures were present in 53 patients, hemothorax in 46 patients, pneumothorax in 25 patients, and pulmonary contusions in 18 patients. Width and length of hemothorax were measured on supine chest AP radiograph, and were correlated with known drained amount of hemothorax. The presence and number of rib fracture, pulmonary contusion, subcutaneous emphysema, fracture of scapula and clavicle, and total opacification of hemithorax were also correlated with the drained amount of hemothorax. RESULTS: In multiple logistic regression analysis, width of hemothorax had the highest correlation with drained amount of hemothorax(regression coefficient 0.718, p value 0.00005). The presence and number of rib fracture, scapular fracture, subcutaneous emphysema were also correlated with drained amount of hemothorax. But length of hemothorax, pulmonary contusion, clavicular fracture, total opacification of hemithorax were not correlated with drained amount of hemothorax. CONCLUSION: Measured width of hemothorax in supine chest AP radiograph is the most reliable predictor for estimation of the amount of hemothorax, and may also be used as an indication for the application of closed thoracostomy in the treatment of hemothorax.

OBJECTIVE: The purpose of this study was to compare cognitive flexibility abilities, stress, and anxiety between starters and non-starter athletes. METHODS: A total of 30 male professional-soccer and 40 professional-baseball athletes were recruited. Wisconsin Card Sorting Test (WCST) and Trail Making Test A & B (TMT A & B) were administered to assess cognitive flexibility during competition. The Korean version of the STAI form Y (STAI-KY) and Visual analogue scale for anxiety and stress were used to assess the anxiety and stress. RESULTS: The starter group had better cognitive function (fewer perseverative errors and rapid TMTB times) (Z=3.32, p<0.01; Z=2.20, p=0.03, respectively) and lower stress and anxiety (F=4.34, p=0.01; F=6.61, p<0.01, respectively) during competition than the non-starter group. CONCLUSION: The better cognitive performances were negatively correlated with stress and anxiety. Current results suggested that cognitive flexibility would enhance human performance by modulation of the anxiety and stress during competition.

Objectives: : This study aimed to characteristic the systolic blood pressure (SBP), diastolic pressure, pulse pressure, glucose, creatine, and lipid profile. This study also aimed to investigate the prevalence of hypertension and the relationship between hypertension and the lipid profile in Uzbekistan. Methods: The subjects consisted of 58 Uzbekistan subjects recruited from Ewha Medical Care patients. Blood samples were collected from the patients for the lipid profile and random glucose and creatinine levels. Paired t tests were used for the group means and a chi-square or Fisher’s exact test for categorical variables. A multiple logistic regression analysis was performed. Results: Among the 58 patients constituting the baseline population, hypertension developed in 42 patients. Among them, the triglyceride (TG) level was significantly higher in the hypertension group than normal group (173.19 vs. 127.06 mg/dL, P=0.014). The SBP had a positive correlation with the TG (r=0.979, P<0.01) and creatinine (r=0.002, P<0.05) levels and also, the pulse pressure had a positive correlation with the cholesterol level (r=0.539, P<0.05). A multivariate analysis (adjusted for age and sex) indicated that there was a positive correlation between the SBP and TG level (r=0.941, P<0.05). Conclusion There was a positive correlation between the SBP and TG level in the Uzbekistan population according to this study.

OBJECTIVES : We investigated the relationship between periventricular and deep white matter hyperintensity and cognitive function in Alzheimer's disease (AD) and mild cognitive impairment (MCI). METHODS : T2-weighted MRI scans were performed in 41 subjects with AD 38 subjects with mild cognitive impairment and 38 control subjects. Periventricular and deep white matter hyperintensities were rated on a Fazekas 0-3 scale by a medical specialist of the department of radiology blind to clinical diagnosis. Cognitive function was assessed by using Cognitive Assessment and Reference Diagnoses System. RESULTS : No significant differences between demographic characteristics and vascular risk factors were revealed comparing AD, MCI and controls. The frequencies of AD were significantly higher than those of MCI and normal control in Grade 2 and 3 of periventricular hyperintensity and Grade 3 of deep white matter hyperintensity. The scores of amnesia, executive function and attention were significantly lower in Grade 2 and 3 of periventricular hyperintensity than in Grade 0 and 1. The scores of attention were significantly lower in Grade 3 of deep white matter hyperintensity than in Grade 0, 1 and 2. CONCLUSION : Periventricualr hyperintensities are associated with cognitive decline in amnesia, executive function and attention, while deep white matter hyperintensities are associated with cognitive decline in attention.

OBJECTIVES: We aimed to determine whether the adult attachment styles of pregnant women could predict development of postpartum depression. METHODS: Korean version of Revised Adult Attachment Scale, State Trait Anxiety Inventory-State/Trait (STAI-S/T), and Center for Epidemiologic Studies-Depression Scale (CES-D) were administered at baseline. Edinburgh Postnatal Depression Scale (EPDS), Parenthood Stress Questionnaire (PSQ), STAI-S, and CES-D were assessed at week 2 and 6 postpartum. Participants were categorized into the secure-mom (SM ; n=48) or insecure-mom (IM ; n=9) group. RESULTS: While STAI-S scores in SM showed a continuous decrease during the entire observation period, STAI-S scores in IM decreased during the first two weeks but increased during the next four weeks. While SM showed decreased CES-D scores from week 2 to 6, IM showed increased CES-D scores from week 2 to 6. Although SM showed decreased EPDS scores from week 2 to 6, IM showed increased EPDS scores from week 2 to 6. In SM, the change in EDPS score from week 2 to week 6 showed positive correlation with PSQ-ability and PSQ-social subscale scores. CONCLUSION: Assessing the maternal adult attachment style before giving birth appears to be helpful for screening the high-risk group who are vulnerable to development of postpartum depression.

Pulmonary thromboembolism (PTE) originating from a renal vein thrombosis (RVT) is very rare, especially in relatively healthy young women. The patient described herein presented with a syncope-associated massive PTE. She was previously healthy, except for termination of an ectopic pregnancy with methotrexate 4 months before. The only medication she was taking was an oral contraceptive (OC), which was started 3 months before the PTE. She had no family history of venous thromboembolism (VTE) or any other underlying risk factors. We report the case of a woman who had a PTE originating from a RVT associated with OC use after an ectopic pregnancy.

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.
