Pancreatic pseudocyst occurs as a complication of pancreatitis or trauma, which results in the escape of pancreatic enzymes from the parenchyma or ductal system of pancreas. At that time, serum amylase may have returned to normal level, and the patient may be subjectively asymptomatic. In this phase, the radiologic findings are relatively greater significance than laboratory data. In the conventional radiologic study, pancreatic pseudocyst have been frequently confused with other retroperitoneal mass, but recently with clinical application of ultrasound and CT scan, more accurate diagnosis can be obtained. The brief results are as follows; 1. Male to female ratio was 3:2 in 15 patients. Incidence was most common in young adult age. Most frequent symptom was epigastic pain, and which was noted in 11 cases of patients. 7 cases of patients had past history of abdominal trauma and past history of pancreatitis was only in 1 case. Most common laboratory finding was leukocytosis in 8cases of patients and elevated serum amylase was also noted in 7 cases. 2. In each 5 cases of patients, plain chest roentgenologic evidence of left side pleural effusion and hemidiaphragm elevation were observed. 3. On flat abdomen film, soft mass shadow was visualized in 8 cases of patients. On UGI series, evidence of retrogastric space widening was observed in 11 cases of patients. 4. The location of pseudocyst is mainly in body and tail of pancrease in 11 cases of patients. 5. More accruable diagnosis can be obtained through application of ultrasound and CT scan.

We identified the early and late prognostic factors of acute myocardial infarction, and evaluated the clinical differences and the prognosis between Q-wave myocardial infarction and non-Q wave myocardial infarction. Total 146 patients who were managed from Jan 1987 to Aug. 1989 at hallym University hospital were evaluated. According to the presence or absence of Q wave on electrocardiogram, the patients were divided into two groups : a Q wave myocardial infarction group(QMI) and a non-Q wave myocardial infarction group (NQMI). Among 146 patients 109 patients(74.7%) had QMI and 37 patients(25.3%) had NQNI. The mean age, male to female ratio and serum cholesterol level were similar in both groups. But peak level of CPK was significantly higher in the QMI group than that in the NQMI group(P<0.01). Left ventricular end-systolic dimension and ratio of left ventricular dimension to wall thickness in the QMI group were significantly higher than that in the NQMI group(P<0.01). There were no significant differences between two groups in the incidences of mortality, postinfarction angina and re-infarction. During the in-hospital period female gender, old age(more than 60 years), Killip class at admission, early reinfarction and a history of hypertension were significant prognostic factors. main causes of death during the in-hospital period were ventricular tachyarrthymia, heart failure and cardiogenic shock. The incidences of mortality, heart failure and post-infarction angina during a mean follow-up period of 14 months (6~30months) were same in the two groups. The late prognostic factors were old age(more than 60 years), Killip class at admission, heart failure occured during follow-up period(P<0.001) and a history of diabetes mellitus(P<0.05). The patients with late postinfarction angina had more dilated left ventricular end-systolic demension(P<0.05) and lower fractional shortening(P<0.01) than those of patients without late postinfraction angina. There were no significant difference in long term survival rate between QMI group and NQMI group. Further prospective study should be performed to clarify the short and long term prognosis in patients with acute myocardial infarction treated by reperfusion.

PURPOSE:We report the results of image-guided percutaneous biopsies with a biopsy gun and evaluate the clinical usefullness. MATERIALS AND METHODS: One hundred and five biopsies under ultrasonographic or fiuoroscopic guidance were performed. Various anatomic sites were targeted (liver;50, chest;22, kidney;12, pancreas;8, intraperitoneum;7, retroperitoneum; ). RESULTS:Obtained tissue was diagnostic in 98 of the 105 biopsies(93%). In each instance, representative core tissue specimens were obtained. Evaluation of the core tissue by pathologist revealed consistent, uniform specimens that contained significant crush artifact in no case. Five biopsies yielded inadeguate tissues which were too small for histopathologic interpretation or were composed of necrotic debris. Two biopsies yielded adequate tissues, but tissues were not of the target. The diagnoses were malignancy in 77 biopsies and benign disease in 21 biopsies. No complications other than mild, localized discomfort were encountered except a transient hemoptysis and pneumothorax which was observed in two patients. CONCLUSION:Cutting biopsy with a biopsy gun provided sufficient amount of target tissue for an accurate diagnosis of malignant and benign disease. It was a safe and useful procedure for percutaneous biopsy.

A 18 year-old man presented with dyspnea and a swelling of the neck. On physical examination, maculopapular rashes were noted on the face and the whole body and crepitus was noted at the thorax and upper arms. His chest X-ray showed bilateral interstitial infiltrates of the lung, pneumomediastinum and subcutaneous emphysema. On serologic examination, measles IgM was positive. Under the diagnosis of measles pneumonia, the patient was treated with oral ribavirin, which resulted in a complete resolution of the pneumomediastinum, subcutaneous emphysema, pneumonic infiltrate, and subjective symptoms of dyspnea and swelling of the neck in 7 days. Here we report this case with a brief review of the relevant literature.

It is well known that the murine T helper cell clones are divided by their lymphokine secretory activities. One is the Th-1 cell, producing IL-2 and IFN after stimulation and the other is the Th-2 cell, producing the IL-4 and IL-5. This study was undertaken to evaluate the immunomodulatory properties of the bacterial lipopolysaccharide(LPS) on the lymphokine production in vivo and in vitro. The results were as follows: There were no effects on the lymphokine secretion by the in vitro treatment of the LPS. The in vivo treatment of the LPS decreases the capability of the production of IL-2 and IFN , whereas it increases the capability of IL-4 production. The altered capacity of the lymphokine production was recovered about 2 weeks after the treatment of the LPS. There were no differences on the lymphokine production between E-coli LPS and salmonella LPS. The capacity of the lymphokine production was the same in the treatment of a non-heated LPS or heated-LPS. The lymphokine production of the mice which were desensitized by the long term treatment of the LPS was not different from the control mice. The in vitro treatment of RU486 can block the alterations of the lymphokine production after the treatment of the LPS. In summary, one can tell that the LPS increases the secretion of the IL-4 through the endogenous secretion of the glucocorticoids.

BACKGROUND: An autopersion balloon catheter(ABC) was developed to allow passive myocardial perfusion during balloon inflation, through a central and multiple side hole in the shaft proximal and distal to the balloon. The ABC affords greater safety in performing PTCA of high risk stenosis involving the near ostium of the right coronary, the proximal left anterior descending(LAD) just proximal to the left circumflex artery and left main equivalent coronary arteries. METHODS AND RESULTS: In case 1, a seventy five percent right coronary ostial stenosis was reduced to less than 10 percent residual narrowing after PTCA with the ABC. In case 2, a seventy five percent proximal LAD(just proximal to left cirumflex artery) stenosis was reduced to less than 20 percent residual narrowing after PTCA with the ABC. In case 3, coronary angiogram demonstrated a 40 percent stenosis in the distal left main coronary artery as well as 80 percent stenosis in the proximal LAD.PTCA with the ABC was performed without significant hemodynamic compromise, achieving a less than 20 percent and 40 percent residual stenosis of the distal left main and proximal LAD respectively. CONCLUSIONS: 3 patients who would have required CABG had PTCA using the ABC.This ABC significatly reduces ischemic symptoms and signs during PTCA, allowing prolonged of balloon inflation.

Those composing temporomandibular joint (TMJ) complex such as the temporal bone, the disc and the mandibular condyle perform their own functions with organic relation. The retrodiscal tissue is the main area of pain induction and contributes to compositional change of synovial fluid. If displacement of the disc lasts long time, not only adaptive changes, but also destructive or degenerative changes may happen. It was reported that these changes and symptoms appear mostly to female rather than male and especially, in the case of patients suffering from TMJ disorder, a large quantity of female sex hormone is found in the joint synovium. And that may play a role in bone resorption and inflammation. Also, the frequency and the intensity of pain perception for female is reported to be much more than for male. In this study, we investigated the expression extents of estrogen receptors (ER) and progesteron receptors (PR) in retrodiscal tissue with immunohistochemistry among the patients received TMJ surgery and compared with MRI findings and surgical findings. We report the relations between the expression of ER in retrodiscal tissue and the pathological change in TMJ, such as inflammation, internal derangement and osteoarthritis.

The use of digital technology in fixed prosthetic treatment using implants enables predictive treatment through diagnosis and virtual surgery by integrating clinical and radiological information of patients. Existing digital scanning methods require several components to be removed, such as removing the healing abutment and connecting the scan body. In the scannable healing abutment developed in consideration of this point, scanning is performed directly on the healing abutment, maintaining soft tissue sealing and simplifying scanning. Digital technology can also be used when obtaining the intermaxillary relationship. Recently, various digital technologies have been reported to acquire the intermaxillary relationship of edentulous patients using surgical guides, patient-specific scanning devices, or scans of the inside of temporary dentures. In this case, the implant-supported fixed prosthesis treatment was performed through scanning the scannable healing abutment and the inner side of the temporary denture to obtain the intermaxillary relationship, thereby simplifying the treatment process and obtaining aesthetically and functionally excellent clinical results.

In order to fabricate stable dentures in patients with severe resorption of residual ridges, various factors must be considered. One of them is the neutral zone, which is defined as the potential region in which the pressure of the tongue outward in the oral cavity and the pressure of the cheeks and lips directed inward from the outside of the oral cavity equalize during functioning. In patients with severe ridge resorption, if the teeth are usually arranged above the residual ridge, the teeth are located on the lingual side rather than the original position. Therefore, the functional space of the tongue is invaded, the tongue is positioned backward, and the sealing of the lingual border is broken, which acts as a factor reducing the maintenance of denture. In addition, it is also important for the stability of dentures to assume an interalveolar crest line connecting the maxillary and mandibular ridge crests, and to arrange the maxillary and mandibular artificial teeth to match the masticatory force to the interalveolar crest line. Therefore, good clinical results were obtained by fabricating dentures for the patient with poor alveolar residual ridge using neutral zone impression and ridge relationship analysis.
