Carbon monoxide poisoning is one of the most serios health problems in Korea, because we have been encountered with the highest incidence of CO poisoning in the world due to the unique heating system in home called "ondal". We opened Hyperbaric chamber unit in the Seoul National University Hospital last Jan, 1969. We have treated 848 patients as of Sept. 30., 1972, around 44 months period. We collected the informations on the environmental conditions of the place where CO intoxication actually occurred by filling up the questionaire from 505 patients. The following finding were obtained. 1. Age distribution showed that the highest incidence was found in the younger age group between age of 10 to age of 29 in both sex. 2. Sex ratio of the patients was 1:1.14. 3. The socio-economic level of the patient was relatively low. 4. Housewife & housemaid were the major victims of the intoxication in the female patients & in the case of the male patient, occupational backgrounds were diverse. 5. Many patients form the middle class experienced the intoxication bu sleeping at newly built room. 6. Many intoxication has been occurred in the structure of houses where communicating doors are existing between living room & kitchen. 7. All findings obtained taught us again that CO poisoning is the serious by-product of the national fuel policy which put emphasis on the use of coal & socio-economic status is very important parameter in this hazards.

Over a period of recent 12 months, 41 patients who had localized pulmonary lesions, but were not diagnosedpathologically through bronchoscopy, transbronchial biopsy, sputum examination and cervical lymph node biopsy,underwent percutaneous needle aspiration and biopsy with a diagnostic accuracy of 83% concerning malignancy vs.benignity and 78% considering the specific cell types as well. Six patients developed small asymptomaticpneumothorax and the other three develped small amount of hemoptysis; One of them required treatement. There were21 malignancies and 14 benign lesions. Three cases were misinterpreted and five were inconclusive on cytology,maybe due to inadequate material. No material was aspirated in one case due to hardness of the mass, which, later,confirmed chondroarcoma on surgery. The method, problems and complications are discussed. Nowadays, thepercutaneous needle aspiration and biopsy appears to be the procedure of choice in pulmonary coin lesionsespecially when they are smaller, more peripheral, and whenever meastatic neoplasm in suspected.

Compliance of epileptic patients is one of the most important factors for adequate therapy. Recently, it had been shown that the variability of three serial measurement of the serum levels of antiepileptic drug(AED) may be used as an indication of the degree of compliance. Coefficient variation(CV) of serum drug levels calculated by only one AED had been used to determine the compliance in epileptic patients who took multiple AEDs. We attempted to evaluate the CV of AEDs and then find the objective clue of compliance and the compatible therapeutic planing according to CV. Ninety seven epileptic patients of outpatients department of the Gyengsang National University Hospital were entered to this study. All patients were taking medication at least for 6 months without any changes of drug regimen. Patient's information was acquired by reviewing the chart and interview with questionnaire. With these informations, we determined the compliance of the patients. Antiepileptic serum levels were measured three times at intervals of at least two to four weeks apart, and their CV was calculated. We compared the CV between the compliant and non-compliant group in each AED(phenytoin, carbamazepine , valproic acid) and three drugs in the compliant group. The mean CVs of phenytoin, carbamazepine and valproic acid in the compliant group were 18.3+/-13.0, 15.2+/-10.2 and 23.8+/-8.9, respectively(mean+/-SD). The mean of CV in the compliant and the non-compliant group were 17.9+/-10.9 and 38.8+/-27.2, respectively. The CVs of the compliant group were significantly lower than those of the non-compliant group(p<0.05). However, CVs had no significant difference between three antiepileptic drugs. This study showed that CVs of AEDs were not different between each AEDs, even though they possess different pharmacokinetic properties. Therefore, the CV of one AED can be used in determining the compliance of the epileptics who are taking multiple AEDs.

Antioxidants oppose the toxic actions of lipid peroxides and oxygen radicals, and they limit the amount of lipid peroxides formed. Women with normal pregnancies have an increase in oxidative stress and lipid peroxidation when compared with nonpregnant women. The antioxidants also increase progressively with advancing gestation, and the antioxidants in the fetus also increase with advancing gestation, especially during late gestation. The purpose of this study is to investigate the diefference of antioxidant status in maternal and neonatal plasma according to the delivery type. So, we investigated the status of antioxidant in the maternal and neonatal plasma when compared normal vaginal delivery with Cesarian section without labor. This study was done under the hypothesis that labor pain is originated from the hypoxic state of myometrium during uterine contraction. The number of women who were studied was total 56, 24 women were delivered by normal vaginal delivery and 32 women were done by Cesarean section without labor. The blood was sampled during active labor and postpartum 24 hour in the case of normal vaginal delivery, the women who were done Cesarean section being sampled before operation and 24 hours after operation. The neonatal blood was sampled from cord, birth 1 day and 3 day. The antioxidant levels were measured by Total Antioxidant Status (Randox Laboratory Ltd., UK) kit. The results were as follows. 1. The mean maternal plasma antioxidant status was not significantly different according to delivery types and not significantly different when compared antepartum with postpartum (vaginal delivery; antepartum: 1.54+/-0.31 mM/L, postpartum: 1.58+/-0.32 mM/L, Cesarean section; antepartum: 1.55+/-0.29 mM/L, postpartum: 1.56+/-0.33 mM/L). 2. The neonatal antioxidant status was not significantly different between the neonates who were born by vaginal delivery and the neonates who were born by Cesarean section. The neonatal plasma antioxidant status was increased progressively after birth (cord: birth 1 day: birth 3 day=1.46+/-0.25 mM/L: 1.59+/-0.25 mM/L: 1.79+/-0.37 mM/L). Therefore, labor pain was not seems to be significantly affect the maternal and neonatal plasma antioxidant status. And the neonatal antioxidant status was increased for adaptation to the external environment after birth.

A 18 year-old man presented with dyspnea and a swelling of the neck. On physical examination, maculopapular rashes were noted on the face and the whole body and crepitus was noted at the thorax and upper arms. His chest X-ray showed bilateral interstitial infiltrates of the lung, pneumomediastinum and subcutaneous emphysema. On serologic examination, measles IgM was positive. Under the diagnosis of measles pneumonia, the patient was treated with oral ribavirin, which resulted in a complete resolution of the pneumomediastinum, subcutaneous emphysema, pneumonic infiltrate, and subjective symptoms of dyspnea and swelling of the neck in 7 days. Here we report this case with a brief review of the relevant literature.

INTRODUCTIONDeveloping effective exercise programmes for the paediatric population is a strategy for decreasing obesity and is expected to help in eventually limiting obesity-associated long-term health and societal impact. In this study, the effects of a 12-week twice weekly additional exercise training, which comprised a combination of circuit-based resistance training and aerobic exercises, in additional to typical physical education sessions, on aerobic fitness, body composition and serum C-reactive protein (CRP) and lipids were analysed in 13- to 14-year-old obese boys contrasted with a control group.

MATERIALS AND METHODSBoth the exercise group (EG, n = 12) and control group (CG, n = 12) participated in the typical 2 sessions of 40-minute physical education (PE) per week in schools, but only EG participated in additional 2 sessions per week of 45 to 60 minutes per session of exercise training, which comprised a combination of circuit-based resistance training and aerobic exercises maintained at 65% to 85% maximum heart rate (HRmax = 220 - age). Body composition was measured using dual energy X-ray absorptiometry (DEXA). Fasting serum CRP and blood lipids were analysed pre- and postexercise programme. Aerobic fitness was measured by an objective laboratory submaximal exercise test, PWC170 (Predicted Work Capacity at HR 170 bpm).

RESULTSExercise training significantly improved lean muscle mass, body mass index, fitness, resting HR, systolic blood pressure and triglycerides in EG. Serum CRP concentrations were elevated at baseline in both groups, but training did not result in a change in CRP levels. In the CG, body weight increased significantly at the end of the 12-week period.

CONCLUSIONThis study supports the value of an additional exercise training programme, beyond the typical twice weekly physical education classes, to produce physiological benefits in the management of obesity in adolescents, including prevention of weight gain.

Objective: This study investigated the influence of psychosocial factors on medical students’ quality of life (QOL). Methods: A total of 408 medical students participated in this study. We collected data on participants’ sociodemographic details, symptoms of depression and Internet addiction, self-esteem, social support, and QOL. QOL was assessed using the World Health Organization Quality of Life-Abbreviated form, which has four domains (physical health, psychological health, social relationships, and environment). A stepwise multiple linear regression model was constructed to identify factors’ independent impact on QOL. Results: Higher levels of depression and Internet addiction were associated with lower scores in all domains of QOL, whereas higher levels of self-esteem and social support were associated with higher scores. Being in third-year versus first-year was associated with higher scores in the physical health and environment domains. Living alone or in dormitories, low or middle socioeconomic status, and insufficient or moderate pocket money were associated with lower scores in the environment domain. Additionally, female students displayed significantly lower scores for physical health, psychological health, and environment than male students, but not for social relationships. There were significant differences in certain domains of QOL due to sociodemographic factors. Conclusion This study demonstrates the psychosocial factors influencing medical students’ QOL. Educational strategies focusing on strengthening self-esteem and social support as well as preventing depression and Internet addiction may contribute to improving medical students’ QOL.

To generate on-board digital tomosynthesis (DTS) for three-dimensionalimage-guided radiation therapy (IGRT) as an alternative to conventional portal imaging or on-board cone-beam computed tomography (CBCT), two clinical cases (liver and bladder) were selected to illustrate the capabilities of on-board DTS for IGRT. DTS images were generated from subsets of CBCT projection data (45, 162 projections) using half-fan mode scanning with a Feldkamp-type reconstruction algorithm. Digital tomosynthesis slices appeared similar to coincident CBCT planes and yielded substantially more anatomic information. Improved bony and soft-tissue visibility in DTS images is likely to improve target localization compared with radiographic verification techniques and might allow for daily localization of a soft-tissue target. Digital tomosynthesis might allow targeting of the treatment volume on the basis of daily localization.
