PURPOSE: The purpose of this study was to identify the relationship of job stress, state of sleep, and depression and to identify factors influencing depression of emergency medical technicians. METHODS: The research was a cross-sectional, descriptive study. Data collection were done using self-report questionnaires with 162 emergency medical technicians working in hospitals who agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression with the SPSS/WIN 18.0 Program. RESULTS: Depression had significant negative correlations with state of sleep, (r=-482, p<.001) and positive correlations with job stress (r=.196,p=.013). State of sleep had significant negative correlations with job stress (r=-.168, p=.033). The variance for life satisfaction was 23.7% (F=25.964, p<.001). Variable of state of sleep significantly predicted depression of emergency medical technicians. CONCLUSION: Considering these results, for emergency medical technicians' job stress, state of sleep, and depression, further studies are needed. Furthermore, there is a need to develop and implement new strategies to improve depression among emergency medical technicians.

Ceftizoxime sodium is a new synthetic β-lactam antibiotic combining potent antibacterial activity with high stability to a wide range of bacterial β-lactamase. This experiment was achieved to evaluate the antibacterial activities of ceftizoxime sodium against. Gram negative enteric bacteria isolated from in outpatient visiting Yeungnam university hospital and to study the emergence of drug induced bacterial variants which resist to ceftizoxime in vitro. The antibacterial activity of the ceftizoxime was compared with that of antibiotics and its effect on population of normal intestinal flora in mice was observed. The results are summarized as follows: 1. Highly effective antibacterial activity of ceftizoxime against Gram negative enteric bacilli was demonstrated and this antibacterial activity was superior to that of ampicillin. 2. Several test strains shows multiple antibiotic resistance. Among 15 strains of Escherichia coli, 1 strain was resistant to ampicillin, cefadroxil, gentamicin, tetracycline, and 2 strains were resistant to ampicillin, cefadroxil, tetracycline, five strains of Escherichia coli and Enterobacter cloacae was resistant to ampicillin, tetracycline and Shigella dysenteriae was resistant to ampicillin, gentamicin, tetracycline. 3. The frequency of in vitro emergence of resistant variants among ceftizoxime sensitive bacteria in the presence of increasing concentrations of the compound was found to be low. 4. Plasmid was isolated in 6 of 9 strains (6 strains of Escherichia coli, Shigella dysenteriae, Enterobacter cloacae and Salmonella typhi). That showed different antibiotic resistance. They were 5 strains of Escherichia coli and 1 strain of Shigella dysenteriae. However, plasmid could not be considered as a hallmark for antibiotic resistance by this Further studies with curing experiment are to be accomplished for this purpose. 5. Changes in the bacterial count of normal intestinal flora following 25 mg/kg/day administration of ceftizoxime over 5 consecutive days were not significant. In conclusion, ceftizoxime appeared to be a drug of choice in the treatment of Gram negative enteric bacilli infection.

Congenital origin intestinal obstruction are important disease due to required emergency operation. So accurate and rapid diagnosis needed for decreased mortality and morbidity. Radiologic must defect to accurate obstruction site and also associated other congenital anomalies. And also embryological basis are very important role to the diagnosis of these diseases. We were analyzed radiologically and clinically 25 cases with congenital origin intestinal obstruction with review of literature. 1. Hypertrophic pyloric stenosis 6 cases, midgut malrotation 4 cases, congenital megacolon 8 cases, imperforated anus 5 cases, ileal atresia 1 case and duodenal atresia 1 case. 2. Male and female radio was 16:9. Especially on hypertrophic pyloric stenosis, 5 cases were male infants. 3. All cases of hypertrophic pyloric stenosis represented string sign and also pyloric beak sign, shoulder sign on UGI. 4. 1 case duodenal atresia showed double bubble sign on simple abdomen x-ray and ileal atresia showed mechanical small bowel obstruction sign with microcolon. 5. On midgut malrotaton, cecum was located in right upper abdomen on 4 cases. And 2 cases were associated with Ladd's band, 1 case with volvulus and 1 case with mesenteric defect. 6. Involved site of all congenital megacolon were localized to rectosigmoid colon. 7. On 5 cases imperforated anus, 3 cases were low type and 2 case high type. Rectoperitoneal and rectourogenital fistula were demonstrated on 4 cases.

Cardiac rupture following blunt thoracic trauma is rarely encountered, since it commonly causes death at the scene. With advances in critical care, blunt cardiac rupture has been successfully treated with well-organized team approach including an emergency physician, anesthesiologist, and cardiac surgeon. We encountered a patient with blunt cardiac rupture of the junction of the superior vena cava and right atrium that extended 7 cm to the right ventricular junction. The patient was successfully resuscitated after a closed thoracostomy and pericardiocentesis with fluid loading. Cardiac injury was repaired via mid-sternotomy without cardiopulmonary bypass. The patient recovered without complications and was discharged on the 7th day after surgery.

Although the ultrasonography & CT have been regarded as a primary procedure in the differential diagnosis of upper abdominal mass, the CT was more superior in the diagnosis, its extent and relationship to the bowel in the cases of the leiomyosarcoma & leiomyoma of the stomach than those of the ultrasonography. The authors studied CT findings of 9 cases of pathologically proven gastric smooth muscle tumor (leiomyosarcoma 7, leiomyoma 2) during the last two years. The results were as follows: 1. CT findings of gastric leiomyosarcoma were often quite large mass, average 15 cm in diameter; extensive central necrotic or cystic changes were fou nd in all 7 cases, seen more clearly on postcontract scan; calcification and peripheral rim enhancement of the tumor were seen in one case each other. 2. Metastasis to the liver and the spleen was seen only in one case, which revealed centrally necrotic and ascites was found in one case. 3. Two cases of gastric leiomyoma were smaller in size, average 6.3 cm in diameter than those of leiomyosarcomaj central necrotic or cystic changes were less common and less extensive. 4. If there were no evidence of central necrotic or cystic changes in large peri-or juxtagastric tumor, ohe should consider other diagnostic possibilities such as left lobe hepatoma, exophytic stomach cancer, Iymphoma or other mesenchymal tumors than leiomyosarcoma.

BACKGROUND: Positive end expiratory pressure (PEEP) ventilation is well established as an integral part of the management of patients with the acute lung injury. PEEP is a key element in the treatment of hypoxemia resulting from pulmonary edema. Pulmonary capillary pressure (Pcap) is the most important factor influencing lung edema formation, and an understanding of how Pcap is altered by variations of PEEP or pulmonary arterial occlusion pressure (PAOP) is important to improve the treatment of acute lung injury patients. This study was performed to evaluate the effects of PEEP on the pulmonary capillary pressure in acute lung injury patients. METHODS: This was a prospective study of 11 acute lung injury patients. The effect of PEEP on pulmonary circulation at four different levels (0,4,8, and 12cm H2O) was analyzed. Pcap was estimated visually at bed side with Swan Ganz catheters. The pulmonary vasculature was analyzed by calculating the pressure difference at the arterial and venous parts of the circulation. RESULTS: As PEEP increased from 0 to 12 cm H2O, the mean puhnonary arterial pressure (PAP) and Pcap increased respectively from 22.7 ± 7.4 to 25.3 ± 7.3 mmHg and 15.3 ± 3.3 to 17.8 ±3.2 mmHg (p<0.05). Similarly, PAOP increased from 9.8 ± 2.1 to 12.8 ± 2.1 mmHg and the central venous pressure increased from 6.1 ± 1.6 to 9.3 1: 2.3 mmHg(p<0.05). However, the pressure gradient at the arterial (PAP-Pcap) and venous (Pcap-Pcwp) part of pulmonary circulation remained unchanged at all evaluated PEEP levels. CONCLUSION: Although Pcap increasoo gradually with increased PEEP, the pressure gradient at the arterial and venous part of the pulmonary vasculature remained unchanged at all evaluated PEEP levels in acute lung injury patients.
