PURPOSE: It is not surprising that serologically based epidemiologic studies have documented the high incidence of mycoplasma respiratory infection throughout the world. We studied the epidemiologic and clinical aspects of mycoplasma pneumonia in children if there is any differences in the peak age-related incidence, seasonal predominance and clinical manifestations in compare with other studies reported in Korea. METHODS: We reviewed 1004 cases of Mycoplasma pneumoniae pneumonia diagnosed by clinical manifestations and positive serologyc tests, retrospectively, who were admitted to the department of pediatrics in four university hospitals in Seoul and Inchon during the last 5 years from 1993 to 1997. RESULTS: 1) The age distribution of mycoplasma pneumonia showed highest incidence in children 4-6 years old. There was no difference in sex distribution at any age group. 2) Although there was little difference in annual distribution, it was highest in 1997. 3) Cough was the most prevalent prodromal symptom. 4) Vomiting, Nausea, Abdominal pain and headache were noted as the extrapulmonary manifestations. 5) Pulmonary infiltration was noted mostly in lower lobe lobes on chest X-ray. They showed interstial involvement in 34.5%, lobar involvement in 30.0%, and pleural effusion in 7.8% of the total. 6). As the complications, aggravate or trigger the asthma attack were noted in 4.0%, development of sinusitis in 3.5% and otitis media in 1.4% of the total. There were four cases of aseptic meningitis and one case of lung abscess. CONCLUSIONS: In our survey, there was little or no epidemiologic differences in the incidence of Mycoplasma pneumoniae pneumonia. We can find the increasing tendency of lobar pattern of involvement on chest X-ray in mycoplasma pneumonia in children.

Placement of central venous catheter is the most common cause of central venous thrombosis. In the setting of a functioning of ipsilateral upper extremity arteriovenous fistula (AVF), symptoms with venous hypertension may be exacerbated. We report a case of patient with successful decompression of severe venous hypertension in the left arm, neck and anterolateral chest wall of a patient whose access for hemodialysis was functioning on the left wrist with left innominate vein occlusion. Left axillary vein to right innominate vein Dacron crossing bypass provided prompt and effective maintenance of venous outflow, with complete resolution of venous engorgement of the affected limb and preservation of dialysis fistula.

The spontaneous rupture of abdominal aorto-iliac aneurysm into inferior vena cava or iliac vein is rare, with a reported incidence of 3% to 4% of all ruptured aneurysm(1,2). This is the most frequent cause of a major abdominal arteriovenous fistula (AVF)(1). We experienced a spontaneous rupture of abdominal aorto-iliac aneurysm into left common iliac vein with gastric leiomyoma in a 64 year-old female patient. The management of abdominal aortic aneurysm with neoplasm of digestive organ is still controversial. We have successfully managed these two lesions by simultaneous operation without any surgical complication. We report the case and briefly review the literature.

STATEMENT OF PROBLEM: The use of mouthguard is important as the leisure life is popular today. PURPOSE: The purpose of this study is to investigate the effect of a mouthguard on stress distribution in teeth, maxilla and mandible for maxilla impact. MATERIAL AND METHODS: The 3-dimensional finite element model was based on a CT scan film of an average korean adult when the subject is using a customized mouthguard which was made with the Signature Mouthguard system of Dreve. The load was applied to the upper central incisor cervical area parellel impact force for 0.1sec(L1), The Von-mises stress analysis with a mouthguard and without a mouthguard was compared. RESULTS: The results of this study were as follows: 1. Without the mouthguard, stress was concentrated on teeth and alveolar bone in all load conditions. 2. With the mouthguard, maximum stress value was decreased and stress was dispersed in all load conditions. 3. Stress extinction with the mouthguard was faster than without the mouthguard in all load conditions. CONCLUSION: We acknowledged that the mouthguard has a stress buffer effect as the maximum stress value was decreased and stress was dispersed when impact force was applied.

Superior mesenteric artery syndrome (SMAS) is a rare disease and is seldom seen in patients with abdominal aortic aneurysms. We experienced a SMAS as a result of an enlarged abdominal aortic aneurysm in a 52 year-old female patient who had undergone renal transplant in the right iliac position 8 years previously. The abdominal aortic aneurysm was successfully resected without an extracorporeal bypass during crossclamping, and postoperatively the patient's symptoms were improved and her renal function was well preserved.

Budd-Chiari Syndrome (BCS) is unusual form of portal hypertension caused by occlusion of the hepatic venous outflow and it is often frequently complicated by inferior vena cava (IVC) occlusion. It may vary in its presentation from very mild symptomatology, suggestive of a viral illness, to a very acute form with a fulminant course. In the cases of BCS caused by occlusion of IVC and hepatic vein, none of the standard portal-systemic shunt can be utilized for satisfactory decompression of the liver. We have experienced two cases of BCS, 43 year-old male and 40 year-old male patients, caused by hepatic vein thrombosis associated thrombosis of the IVC. Cavoatrial shunt using Dacron graft and interposition graft between portal vein to cavoatrial graft were performed. Combined porto-cavo-atrial bypass that decompress both the portal system and IVC has been effective in relieving BCS caused by occlusion of hepatic vein with IVC.
