Objectives: This study was performed to investigate the management status of chronic disease at community health centers. Methods: The study subjects were 450 employed persons at community health centers in Jeonlanamdo. General characteristics, status of chronic disease management and health education were collected for statistical analysis. The differences on management status among working areas were assessed with chi-square test and ANOVA. Results: The mean values of work duration were 18.7 years in rural, 14.4 years in fishing village, and 17.4 years in urban-rural, respectively. The number of management registration was highest in hypertension. The ways of disease management were medication check-up, diet stopping smoking. The contents of group health education were exercise, diet and prohibition of smoking. The place of health education was town assembling hall. The fields which officials wanted to be educated were symptom, diagnosis, treatment and complication. The most important field was early detection of chronic disease patients and health education. Finally, the field requiring support was work standardization. Conclusions: Community health workers have worked positively in chronic disease management. The barriers to work were the lack of professional and preliminary data. The support system with other health organ and health education were needed for the improvement of working ability.

Purpose Distinguishing intradural extramedullary (IDEM) spinal ependymoma from myxopapillary ependymoma is challenging due to the location of IDEM spinal ependymoma. This study aimed to investigate the utility of clinical and MR imaging features for differentiating between IDEM spinal and myxopapillary ependymomas. Materials and Methods We compared tumor size, longitudinal/axial location, enhancement degree/pattern, tumor margin, signal intensity (SI) of the tumor on T2-weighted images and T1-weighted image (T1WI), increased cerebrospinal fluid (CSF) SI caudal to the tumor on T1WI, and CSF dissemination of pathologically confirmed 12 IDEM spinal and 10 myxopapillary ependymomas. Furthermore, classification and regression tree (CART) was performed to identify the clinical and MR features for differentiating between IDEM spinal and myxopapillary ependymomas. Results Patients with IDEM spinal ependymomas were older than those with myxopapillary ependymomas (48 years vs. 29.5 years, p < 0.05). A high SI of the tumor on T1W1 was more frequently observed in IDEM spinal ependymomas than in myxopapillary ependymomas (p = 0.02). Conversely, myxopapillary ependymomas show CSF dissemination. Increased CSF SI caudal to the tumor on T1WI was observed more frequently in myxopapillary ependymomas than in IDEM spinal ependymomas (p < 0.05). Dissemination to the CSF space and increased CSF SI caudal to the tumor on T1WI were the most important variables in CART analysis. Conclusion Clinical and radiological variables may help differentiate between IDEM spinal and myxopapillary ependymomas.

Objective: This study was conducted to investigate the awareness of work-related disease prevention of farmers. Method: As a research method, a qualitative focus group interview was conducted in 18 participants. Results: Prevention and management services for work-related diseases of farmers mostly are based on research from other fields and so are not highly effective because their content is not relevant to agricultural work. It has been suggested that such program designers be required to have some appropriate related knowledge, and that incentives and a certification system for participation in such education be established. To analyze work-related diseases of farmers, fields of prevention, diagnosis, treatment, and rehabilitation should be created. They demanded the designation of hospitals and the actualization of compensation for farmers' safety insurance. The work-related diseases to address were include musculoskeletal diseases, pesticide poisoning-related diseases (cardiovascular disease, respiratory disease), psychiatric diseases such as depression, and allergic diseases. However, this must have been the result of the harmful factors they felt during agricultural work. And for farmer patients diagnosed with work-related diseases, it was said to strengthen farmer safety insurance. Conclusion: In order to increase the safely and health effects of agricultural work, it is necessary to prevent and manage work-related diseases of farmers. Projects should be developed in consideration of cultural and economic barriers of farmers and the characteristics of the work.

The mentophysical disease causes diseases in digestive, respiratory, circulating systems, including chronic pain, through combined reactions from different individual characteristics, mental stress and temperamental factors. The most common symptom related to orofacial area is pain and the contributive factors include biological, behavioral, environmental, social, emotional, recognitive factors. These factors affect the course of the symptom according to individual's character and human nature. In pain, sleep acts as a contributive factor, and pain could bring about sleep disturbance and vice versa. Deterioration of sleep quality would act as a factor that aggravates mental stress. Therefore, relatively accurate and simple mental examinations and sleep quality test should be carried out for the patients with symptoms related to orofacial area. This study evaluated the mental state in relation to the sleep quality which could affect orofacial pain. The number of poor sleeper was 18 in male subjects, and 1 in female subjects and PSQI global index was higher in male($6.11{\pm}2.38$) than female($4.67{\pm}2.18$). SCL-90-R index showed no sex difference. Poor sleeper showed significantly high value in SOM, O-C, I-S, ANX, PHOB, PSY, GSI, PST. When SCL-90-R T scores were compared according to sleep quality, higher the subjective sleep quality score, O-C and I-S showed significant increase. As sleep disturbances score increased, PAR, PSY, PST showed statistically significant increase. In comparison of SCL-90-R T score according to daytime dysfunction, statistically significant increase in DEP, ANX, HOS, PHOB, PAR, GSI was observed. Therefore, the quality of sleep and psychological status have a high correlation. This is likely to influence chronic pain in the orofacial field. As a result, clinicians treating orofacial pain should evaluate the sleep quality and psychological status of the patient. Further studies of larger sample sizes including various age, occupation, and pain groups are necessary in order to apply the results to clinical practice.

Chemical pneumonitis is an occupational lung disease that's caused by the inhalation of chemical substances. Its severity depends on the characteristics of the substances, the exposure time and the susceptibility of the patients. Hydrogen sulfide is not only emitted naturally, but it also frequently found in industrial settings where it is either used as a reactant or it is a by-product of manufacturing or industrial processes. Inhalation of hydrogen sulfide causes various respiratory reactions from cough to acute respiratory failure, depending on the severity. Two pharmaceutical factory workers were admitted after being rescued from a waste water disposal site that contained hydrogen sulfide. In spite that they recovered their consciousness, they had excessive cough and mild dyspnea. The simple chest radiographs and high resolution computed tomography showed diffuse interstitial infiltrates, and hypoxemia was present. They were diagnosed as suffering from chemical pneumonitis caused by hydrogen sulfide. After conservative management that included oxygen therapy, their symptoms, hypoxemia and radiographic abnormalities were improved.

Purpose : Malformation of urinary tract is among the most common of all congenital anomalies and can progress to irreversible renal damage before diagnosis due to difficulty of early diagnosis. Present study was undertaken to determine the clinical characteristics of urinary tract anomaly and to find out the most appropriate diagnostic and therapeutic measures for children with these anomalies. Methods : During the past 10 years from 1987 to 1998, review of medical records revealed 65 children with congenital anomaly of urinary tract and the following results were obtained. Results : The most common anomalies were ureteropelvic junction obstruction occuring in 26 cases ($36\%$), followed by ureteral duplication in 11 cases, renal agenesis in 10 cases and ureterovesical function obstruction in 7 cases. Complex anomaly of urinary tract was found in 8 cases and anomaly of other systems such as congenital heart disease was detected in 11 cases. The most frequent age group at the time of diagnosis was below 1 year of age constituting 39 cases ($60\%$) and male preponderance was noted as male to female ratio being 2.25:1. Presenting symptoms were urinary tract infection in 25 cases, followed by hematuria, abdominal mass, abdominal pain and voiding difficulty, etc, and in 11 cases, the anomaly was picked up by routine prenatal ultrasonography. Azotemia was noted in 9 cases and the underlying anomaly was obstructive uropathy in 4 out of these 9 cases. Surgical correction was undertaken in 38 cases (most frequently in cases of obstructive uropathy) and in 2 out off cases with obstructive uropathy in whom surgical correction was done, azotemia disappeared during follow up period of 1-5years. No new cases of deteriorating renal function appeared during follow-up period. Conclusion : In spite of high incidence of congenital malformation of urinary tract, early diagnosis is still hampered by nonspecific symptoms and signs. Therefore, in patients with symptoms such as urinary tract infection, abdominal pain and voiding problems, etc, it Is advisable to take various diagnostic tests promptly to pick up any urinary tract anomaly and to apply proper therapy in order to avoid progression to irreversible renal damage. In this regard, prenatal ultrasonography should be utilized more widely as a routine procedure to detect any urinary tract anomalies before birth.

Purpose: There has been increased the number of early gastric cancer and laparoscopy-assisted gastrectomy (LAG), due to early detection through mass screening program. We started the LAG in April 2004 and performed 119 cases of gastric cancer in 2005, so we report a surgical outcome compared with that of open gastrectomy (OG). Materials and Methods: 119 patients underwent LAG in 2005, and for open group, 126 patiens of early gastric cancer were selected sequentially from January 2005 to March 2005. We compared clinicopathologic characteristics, postoperative courses and complications between two groups. Results: There was no significant difference between age, a length of hospital stay, distal resection margin and a number of retrived lymph nodes. The operation time was longer in LAG group (239.2 vs 123.3 mins, P<0.001) and a diet progression was faster in LAG group (first flatus: 3.05 vs 3.70 days, SOW: 2.86 vs 3.22 days, liquid diet: 3.87 vs 4.19 days, soft diet: 4.84 vs 5.26 days, P<0.001). But there was no difference statistically in postoperative discharge date (7.73 vs 8.25 days, P=0.229). The additional requirement of analgesic injection was less frequent in LAG group (2.97 vs 4.92 times, P<0.001). The harvested lymph nodes were similar in both groups (23.9 vs 23.1, P=0.563). A complication rate was lower in LAG group (4.9% vs 9.5%), but there was no statistical significance (P=0.179). There was no mortality in both groups and no conversion to open gastrectomy in the LAG group. Conclusion: LAG can be performed safely and accepted in view of curative procedure in treatment of early gastric cancer. But we need the follow up of long-term period to evaluate the survival rate and recurrence, and a prospective randomized controlled study should be done to establish that LAG will be a standard operation for early gastric cancer.

Purpose : Among perinatal risk factors, neonatal seizures are one of the strongest independent discriminators of adverse outcome, representing high risks of mortality and neurologic morbidity. This study was undertaken to evaluate the neurologic outcome of neonatal status epilepticus according to underlying etiology, seizure pattern, onset time, and duration. Methods : We reviewed retrospectively 36 neonates(19 males, 17 females) with status epilepticus who were admitted to the neonatal intensive care unit, Inha Hospital between July, 1988 and June, 2003. They were evaluated with neurologic examination, laboratory data, EEG findings, and neuroimaging studies etc. Results : The mean gestational period of the patients was $37.0{\pm}3.6$ weeks and birth weight was $2.70{\pm}0.82$ kilogram. Fifty two point eight percent of the neonates were male and 66.7 percent were born at term. The most common cause of neonatal status epilepticus was hypoxic-ischemic encephalopathy. In preterm babies, intracranial hemorrhages showed an especially high frequency(P=0.034). Gestational age and birth weight did not show a correlation with neurologic complications. The incidence of neurological sequelae were significantly related to prolonged seizures lasting more than 1 hour(P=0.002). Neonates with seizures within the first 72 hours tended to be more frequent among those who developed adverse outcomes(P=0.016). Generalized tonic seizures had the worst prognosis, whereas those children who had subtle seizures had better outcomes than any other type(P<0.05). Generalized tonic seizures were primarily represented on EEG by abnormal background, whereas subtle seizure showed a significantly more normal EEG than any other seizures(P<0.05). Conclusion : Our results indicate that neonatal status epilepticus with early onsets, prolonged durations. And generalized tonic types can predict an increased risk for neurologic sequelae. So, those seizures must be perceived as medical emergencies and treated aggressively with antiepileptic drugs.

Purpose: ¹⁸F-FET, a radiopharmaceutical based on a Tyrosine amino acid derivative using the Sodium-Potassium Pump-independent Transporter (System L) for non-invasive evaluation of primary, recurrent, and metastatic brain tumors, exhibits distinct characteristics. Unlike the widely absorbed ¹⁸F-FDG in both tumor and normal brain tissues, ¹⁸F-FET demonstrates specific uptake only in tumor tissue while almost negligible uptake in normal brain tissue. This study aims to compare and evaluate the usefulness of ¹⁸F-FDG and ¹⁸F-FET Brain PET/CT quantitative analysis in brain tumor diagnosis. Materials and Methods: In 46 patients diagnosed with brain gliomas (High Grade: 34, Low Grade: 12), Brain PET/CT scans were performed at 40 minutes after ¹⁸F-FDG injection and at 20 minutes (early) and 80 minutes (delay) after ¹⁸F-FET injection. SUV_max and SUV_peak of tumor areas corresponding to MRI images were measured in each scan, and the SUV_max-to-SUV_peak ratio, an indicator of tumor prognosis, was calculated. Differences in SUV_max, SUV_peak, and SUV_max-to-SUV_peak ratio between ¹⁸F-FDG and ¹⁸F-FET early/delay scans were statistically verified using SPSS (ver.28) package program. Results: SUV_max values were 3.72±1.36 for ¹⁸F-FDG, 4.59±1.55 for ¹⁸F-FET early, and 4.12±1.36 for ¹⁸F-FET delay scans. The highest SUV_max was observed in ¹⁸F-FET early scans, particularly in HG tumors (4.85±1.44), showing a slightly more significant difference (P<0.0001). SUV_peak values were 3.33±1.13 for ¹⁸F-FDG, 3.04±1.11 for ¹⁸F-FET early, and 2.80±0.96 for ¹⁸F-FET delay scans. The highest SUV_peak was in ¹⁸F-FDG scans, while the lowest was in ¹⁸F-FET delay scans, with a more significant difference in HG tumors (P<0.001). SUV_max-to-SUV_peak ratio values were 1.11±0.09 for ¹⁸F-FDG, 1.54±0.22 for ¹⁸F-FET early, and 1.48±0.17 for ¹⁸F-FET delay scans. This ratio was higher in ¹⁸F-FET scans for both HG and LG tumors (P<0.0001), but there was no statistically significant difference between ¹⁸F-FET early and delay scans. Conclusion: This study confirms the usefulness of early and delay scans in ¹⁸F-FET Brain PET/CT examinations, particularly demonstrating the changes in objective quantitative metrics such as SUV_max, SUV_peak, and introducing the SUV_max-to-SUV_peak ratio as a new evaluation metric based on the degree of tumor malignancy. This is expected to further contributions to the quantitative analysis of Brain PET/CT images.

Purpose : Recently there has been a decrease in ventilator care rate and duration of very low birth weight infants(VLBWI) in Fatima Hospital. The aims of this study were to survey the frequency and duration of ventilation in VLBWI and to develop a non-invasive neonatal intensive care unit (NICU) policy. Methods : We performed a retrospective study of 284 newborn of infants less than 1,500 gm admitted to NICU and discharged from January 1998 to December 2001. Patients were intubated or applied continuous positive airway pressure(CPAP) via nasal prong immediately after presenting signs of respiratory distress. We analyzed epidemiologic data to study the changes in ventilator care rate, duration and outcome of ventilator care groups. Results : Of 284 newborn infants, 146 required invasive management, such as endotracheal intubation and assisted ventilation. The characteristics, the severity of clinical symptoms and laboratory findings in ventilator care groups at birth showed no significant differences. The annual proportion of infants requiring assisted ventilation decreased according to increasing gestational age. The median duration of ventilation decreased markedly from 6.0 days in 1998 to 2.7 days in 2001. Final complications and outcomes in ventilator care groups showed no significant differences. Conclusion : Our study shows a significant reduction in the invasiveness of the treatment of VLBW infants, which was not associated with an increased mortality or morbidity. A non-invasive strategy for the VLBW infant with minimal to moderate respiratory distress after birth in NICU is better than immediate invasive management. Non-invasive nasal CPAP is a simpler and safer method than invasive assisted ventilation.
