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.

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.

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.

The purpose of this study is to clinically evaluate and report the effectiveness of radiofrequency microdebrider (Topaz, ArthroCare) treatment in lateral epicondylitis patients. From March to July 2003, 15 patients of 17 elbows were prospectively followed. Candidate for the treatment were lateral epicondylitis patients who had symptom more than 6 month and failed to respond to conservative treatment, including medication (non-steroidal anti-inflammatory drugs), external gel or patch, and steroid injections. All patient who scored greater than grade 3 (fair) on the Self-administered Roles and Maudsley Pain (SRMP) score were selected for the procedure. All procedure was done using local anesthesia and ArthroCare microdebrider by a single surgeon. Postoperative assessments were done on postoperative period 12 month of two previous subjective scores and a simple functional assessment asking better, same, or worst function after the procedure. Mean age of the patients was 45 years old. Mean symptom duration before the procedure was 22.6 months. After the procedure, the mean Pain Visual Analogue Scale improved from 7.3 (range, 5–9; standard deviation [SD], 1.2) preoperatively to 3.7 (range, 0–7; SD, 2.1) postoperatively (p< 0.001). After the procedure, five elbows showed no rating improvement, in seven elbows 1 level improvement, in four elbows 2 level improvement, and in one elbow 3 level improvement. Overall, 71% (12/17) showed improvement after the procedure according to the SRMP score rating. Although 29% (5/17) of the elbow showed no improvement on SRMP score, among them five elbows were still rated decrease in Pain Visual Analogue Scale.

The formation and development of cytoplasmic inclusion bodies of type II pneumocyte were investigated using 7 cases of human fetal lungs from 9 to 20 weeks of gestation by transmission electron micropscopy. The results obtained were as follows: 1. The multilamellar bodies, the characteristic inclusion body of type II pneumocyte, have developed in developing epithelium of lung at 9 week of gestation. Another inclusion bodies specific to type II pneumocyte also have developed at that time. 2. The inclusion bodies were formed in association with cytoplasmic reticulum, outer membrane of nuclear envelope, and mitochondria. 3. The inclusion bodies were distributed in cluster at the apical cytoplasm, and classified schematically with the contents as multilamellar, cytoplasmic, granular/f locculent, multivesicular, dense, and multilamellar. But the intermediate and composite forms of inclusion bodies appeared at the time toward 20 week of gestation. In summary, it is suggested that the differentiation of type II pneumocyte starts before 9 week of gestation and 4 main types of inclusion bodies considered as the precursor of multilamellar body were found. Although the inclusion bodies were formed at endoplasmic reticulum or etc, it is likely that they form multilamellar body through the complex process such as fusion of inclusion bodies.

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.
