During The last 11 years from Jan. 1980 to Dec. 1990, 72 cases of salmonellosis has been admitted to the Department of Pediatrics of National Medical Center and evaluated clinical difference between typhoid fever and salmonella gastroenteritis. The results were as follows: 1) The annual incidence of salmonella gastroenteritis insalmonellosis was increased in the latter half of the eighties. 2) Both salmonellosis had its peak incidence in the summer. 3) Salmonella gastroenteritis was highest in the age of less than 5 year in contrast with the age of 6~9 year in typhoid fever. 4) The specimens isolated salmonellae were blood and stool in most cases, especially blood in typhoid fever and stool in gastroenteritis. 5) S.typhi was 16 cases, salmonella group A was 3 cases, group B was 16 cases and Group D and E were a case in each in isolated salmonellae. 6) On the antibiotic sensitivity test, S.typhi was sensitive to the most antibiotics. but the salmonella group B was relatively resisitant to Ampicillin, Carbenicillin, Tetracycline and Chloramphenicol.

BACKGROUND: Recently, there are many reports about the association of Diffusion Weighted Imaging (DWI) and the prognosis of hypoglycemic encephalopathy (HE), but those relationships have not yet been completely determined. As such, we researched for prognosis, according to a variety of clinical data, and the lesion's distribution on DWI. METHODS: We retrospectively reviewed 19 patients who were diagnosed as HE. In addition, those prognoses were analyzed by a variety of clinical data and characteristics of lesion's distribution, which were evaluated on DWI and Apparent Diffusion Coefficient (ADC) maps. Three months later, those prognoses were determined by each Modified Rankin Scale. Further, the time-dependent average Glasgow Coma Scale (GCS), among the groups according to the characteristics of lesion's distributions in the initial DWI, was estimated. RESULTS: In this study, the difference of prognosis was not shown, according to all the clinical data, such as the severity or duration of the hypoglycemic state, but the group that did not have any pathologic lesion on the initial DWI demonstrated a better prognosis, in comparison with the groups-that exhibited any positive lesion on the initial DWI (p = 0.006). The group that had a focal pathologic lesion on the initial DWI showed a better prognosis than the diffuse lesion's group (p = 0.045). The groups with no lesion or focal lesion showed a faster recovery of GCS than the other groups with a positive lesion or diffuse lesion within the initial 1 week. CONCLUSIONS: We can identify that the characteristics of the lesion's distribution of DWI can be more helpful to predict of prognosis in HE than a variety of clinical data, such as the severity or duration of the hypoglycemic state.

We report a 58-year-old man who developed synchronous gastric non-Hodgkin`s lymphoma (NHL) and renal cell carcinoma. He presented with epigastric discomfort for 2 months. Endoscopic finding of the stomach disclosed a large inegular ulceration with nodular margin on the upper body. Constrast enhanced CT scan of the abdomen showed an ulceration and focal wall thickening in the greater curvature side of stomach, and an enhanced bulging mass in the left kidney incidentally. The tissue obtained by radical proximal gastrectomy and nephrectomy showed diffuse large B-cell lymphoma on stomach and chromophobic type of renal cell carcinoma on kidney. To our knowledge, this is the first report of synchronous gastric NHL and renal cell carcinoma in Korea.

Pulmonary embolism (PE) is generally thought to occur between days 5 to 7 after acute injury. However, PE can occur early after injury and the features of early PE after injury have not been well studied. We report on two cases of acute PE within two days after thoracic and lower extremity injury. First, a 39-year-old female presented to the emergency department complaining of chest pain and dyspnea. Fifteen hours earlier, she had fallen from a 1 m height drawer at home. She had a history of idiopathic pulmonary arterial hypertension. Initial blood pressure was normal; however, oxygen saturation was 83% on room air. Chest computerized tomography (CT) showed a low density filling defect in the left main pulmonary artery. However, no deep vein thrombus was observed on low extremity CT angiogram. Second, a 21-year-old male was transferred from a local clinic to the emergency department. He had pelvic ramus, right femur shaft and ankle fracture from a motorcycle accident, which had occurred 36 hours ago. Initial vital signs were stable and he had no symptoms related to PE, except leg pain. We performed CT scan in order to rule out injury associated with pelvic bone fracture. CT scan showed filling defects in the segmental pulmonary artery of the left lower lobe. We did not find deep vein thrombus on low extremity CT angiogram. PE related to trauma can occur in early days after injury and is not commonly associated with deep vein thrombus. Emergency physicians should consider PE in the differential for patients with unexplained dyspnea, even early after injury.

Fluoropolymer compounds (polytetrafluoroethylene-PTFE, Teflon(R)) can produce a clinical syndrome, polymer fume fever, when the products from their thermal decomposition are inhaled. Polymer fume fever is characterized by fever, dyspnea, a non-productive cough, and headaches after exposure to the pyrolytic products. We report a case of acute respiratory distress syndrome after the inhalation of fumes produced from overheated fluoropolymer compounds. A 60-year-old male came to the emergency department complaining of severe dyspnea, nausea, coughing. Just one day ago, he worked in a fluoropolymer-processing factory without any protective mask device. Initial arterial blood gas analysis showed a composition of pH 7.4, arterial partial oxygen pressure 46.0 mmHg and oxygen saturation 79% of room air. Chest computerized tomography revealed a bilateral diffuse consolidation and ground glass appearance. Polymer fume fever and acute respiratory distress syndrome was suspected by the symptoms, history of exposure, and radiologic findings. The patient received ventilatory support with a mechanical ventilator, intravenous corticosteroids, and intravenous N-acetylcysteine. His symptoms and oxygen saturation completely resolved over 6 days. In summary, when fluoropolymers compounds are heated the fumes generated can cause polymer fume fever with severe toxic effects, such as acute respiratory distress syndrome, pulmonary edema, and pneumonitis. The clinical presentation, radiologic findings, and the management of polymer fume fever are reviewed here.

OBJECTIVE: The videofluoroscopic swallowing study (VFSS) has been accepted for standard method of dysphagia evaluations. But there is no research for oropharyngeal effects depending on the change of viscosity. METHOD: The 10 normal subjects without dysphagia symptom or history were participated. 4 test foods were selected according to viscosity which was measured by line spread test (LST); thick semiblended diet: LST 1 cm, Yoplait: LST 2.44 cm, tomato juice: LST 3.67 cm, 35% diluted barium: LST 4.15 cm. Each foods were swallowed 3 times during VFSS. We measured oral transit time (OTT), pharyngeal delay time (PDT), pharyngeal transit time (PTT), and cricopharyngeal opening time (CPOT) RESULTS: There was linear correlation between OTT and LST (cm)(r= 0.965, P<0.05). As the score of LST increased, PDT tended to increase linearly, but there was no statistical significance (r=0.949, P=0.509). PTT and CPOT had no significant correlation with viscosity. CONCLUSION: The viscosity affected OTT and PDT. The test foods of VFSS and dysphagia diet shoud be selected by viscosity measures.
