As public awareness of the various warning signs of malignancy increases, so does the concern evoked by the self identified finding of mass in the head and neck area. Not all the palpable masses are always significantly abnormal, but any nontender mass especially to the adult is significant enough to warrant further full investigation and follow up, the object of which should be to determine the possibility of malignancy and urgency of treatment. Approach to the diagnosis of the neck mass is so important in that it affects decision regarding further evaluation would lead to the determination of the most efficacious mode of therapy, eventually to the good prognosis. So, it should be emphasized that approach to the diagnosis of neck mass should be planned, systematic and thorough, this begins with the taking careful history following performance of complete examination of the head and neck especially to the nasopharynx, tongue base, pyriform sinus, palatine tonsil and larynx. Then a number of laboratory and radiologic studies are available, following triple endoscopy under general anesthesia and blind biopsy if needed. The most important rule to keep is that any biopsy procedures should be delayed to the last modality of effort to the diagnosis and if it should be done, under the plan of radical neck dissection.

Calcaneus is the largest tarsal bone and serves weight bearing of the body. The calcaneus has a pattern of cancellous bone enclosed with a very thin cortical shell. It is difficult to reduce the bony fragments accurately when there are comminution and displacement on the calcaneal fractures. Retrospective study was carried out of 18 patients(21 feet) of calcaneus fractures after axial fixation in Soonchunhyang University Hospital from July, 1982 to July, 1988. Minimum follow up period was 8 months(average 2 years 6 months). The clinical analysis of them are reported with a review of the literature and the results are follows:l. According to the Rowe's unit system, the results of treatment were excellent or good in 9 cases of 13 tongue types and 5 cases of 8 joint depression types. 2. The results were satisfactory in the calcaneal fractures of well reestablished Bohler angle to 21-30 degrees. 3. The results were excellent or good in 5 cases operated within post-trauma 1 week and in 9 cases operated from 1 week to 2 weeks. 4. The results were poor in the 2 joint depression type with severe comminution. And subtalar joint fusion was performed on the previous 2 cases. Then pain on the lateral malleolar area was subsided.

Endoscopic sphincterotomy(EST) is now an established therapeutic procedure for various disorder of the pailla of Vater, the biliary tract, and the pancreas. From November 1992 to September l993, 123 cases of E.S.T were performed in our hospital. The success rate of EST was 97.8%, and choledocholithiasis was the indication for EST in 63. 4% of cases. Among 78 cases of choledocholithiasis, 47 cases were presence of gall bladder with stone (16 cases) or without stone (31 cases), especially 46 cases were assisted with needle type papillotome and 23 cases were assisted with guidewire. EST hae relatively low complications and is the therapy of choice for choledocholithiasis and various diisease of biliary tract. Guidewire assisted stanard papillotome probable reduce the use of needle type papillotome in the difficult cases that EST with pull type papillotome was impossible.

In normal hurnan dermis, factor XIIIa positive dermal dendrocyte are located in the papillary areas closely associated with blood vessels and the upper reticular dem These cells represent a specific type of bone marrow derived dermal cells, distinct from Langerhans cells having some features in common with rnonocyte/macrophage lineage and with potential antier presenting activity. Although the significance of these cells has not yet been fully established, it been suggested that they play a major role in skin immune iesponses, in collagen synsthesis regultic and in wound repair. We report a case of acaqired fibrokeratoma which is studiec conventional histopathology and immunohistochemistry. Histopathologic findings of this case showed ovascular proliferation and the increased presence of fibroblast like cells as a common fe;ture of these benign tumors. Immunohistochemical staining with anti factor XIIIa antibody deiaoi strates increased numbera of positive dendritic cells in the upper dermis. There finding supports the fat that some fibroblagt like cells in the upper dermis of acquireid fibrokeratoma may be factor XIIIa positive dermal dendritic cells.

PURPOSE: We evaluated the importance of redistribution and 24 hour reinjection images in Tl-201 SPECT assessment of myocardial viability after acute myocardial infarction (AMI). MATERIALS AND METHODS: We performed dipyridamole stress-4 hour redistribution-24 hour reinjection Tl-201 SPECT in 43 patients with recent AMI (4-16 days). The myocardium was divided into 16 segments and perfusion grade was measured visually with 4 point score from 0 to 3 (absent uptake to normal uptake). A perfusion defect with stress score 2 was considered moderate. A defect was considered severe if the stress score was 0 or l (absent uptake or severe perfusion decrease). Moderate defect on stress image were considered viable and segments with severe defect were considered viable if they showed improvement of 1 score or more on redistribution or reinjection images. We compared the results of viability assess-ment in stress-redistribution and stress-reinjection images. RESULTS: On visual analysis, 344 of 688 segments (50%) had abnormal perfusion. Fifty two (15%) had moderate perfusion defects and 292 (85%) had severe perfusion defects on stress image. Of 292 severe stress defects, 53 were irreversible on redistribution and reversible on reinjection images, and 15 were reversible on redistribution and irreversible on reinjection images. Two hundred twenty four of 292 segments (76.7%) showed concordant results on stress-redistribution and stress-reinjection images. Therefore 24 hour reinjection image changed viability status from necrotic to viable in 53 segments of 292 severe stress defect (18%). However, myocardial viability was underestimated in only 5% (15/292) of severe defects by 24 hour reinjection. CONCLUSION: The 24 hour reinjection imaging is useful in the assessment of rnyocardial viability. It is more sensitive than 4 hour redistribution imaging. However, both redistribution and reinjection images are needed since they complement each other.

BACKGROUND: The functional dyspepsia gives rise to such a symptom similar to peptic ulcer without showing a noticeable lesion(e.g, gastric or duodenal ulcer) by endoscopy or upper GI serises, and it has been known that this is about twice as many as the peptic ulcer. However, there is no exact theory about its pathophysiology and it is suggested that multiple factors including genetic, physiologic, psychologic, environmental factors are engaged. Especially, in respect to the occurrence of functional dyspepsia and psychological factors, there have been many clinical studies over the world. But, we still need more studies in this country, therefore, this study has been initiated to give help patients of functional dyspepsia, invest.igating their characteristic traits through MMPI. METHODS: From March to September in 1996, the patients who visited the family medicine out-patients department of St. Marys hospital of Catholic Medical College were sampled in this study. There were 46 patients having a similar symptoms to peptic ulcer without showing pathologic lesions by endoscopy. Through an interview and some basic tests, the 41 controls who had no dyspeptic symptoms and were not affected to a noticeable physical or physiological disorders were selected for the normal reference group. The standardized MMPI of our country was applied to the whole object groups to get a result. Then each average value of the measure(mean T-score) was calculated, and the differences of the average value were analyzed by the t-test and chi-square test. And the psychological pattern analysis was done. RESULTS: In demographic aspects, there were no significant differences between the two groups. The mean T score for each measure of the two groups falls within the normal ranges with their values being of between 30 to 70. And the average of L, F, and K measure, known as the validity measure, did not give a significant differences between the two groups. The measure of Hs, D, and Hy have appeared significantly high in the patients group(p<0.01) and the Pd measure, too(p<0.05). While Mf, Pa, and Ma measure have not shown a significant differences, Pt, Sc, and Si measure have very significant differences(p<0.01). CONCLUSIONS: In the patient group with the functional dyspepsia, the measures of Hs, D, and Hy where they indicate a neurotic pattern have shown a very significantly high point as well as those of Pd, Pt, Sc, and Si where they indicate a psychotic pattern. This reveals that in the group of the functional dyspepsia neurotic or psychotic trends to attribute. However, it is very hard to define the characteristics of a group with just one test, so further study with more variable test will be necessary.

Plain chest films are the most useful modality in diagnosis of primary lung cancer, but it is difficult tointerpret the radiologic findings by histological types. Authors reviewed chest films of 324 cases ofhistologically confirmed primary lung cancer from Jan. 1974 to April 1982 at Seoul National University. The resulsare as follows; 1. Incidence was most common in the 6th decade as 34.4%. Male to female sex ratio was 3.8:1 andthere was no sex difference in Adenocarcinoma. 2. Distrubution of histologic types of primary lung cancer asfollows; Squamous cell Carcinoma 50.6%, Small Cell Carcinoma 22.5% lange Cell Carcinoma 9.3% Bronchegenic adenocaranoma 10.5% Bronchioloalveolar Cell Carcinoma 1.9%. Adenosquamos Carcinoma 0,6%, Carcinoid Tumor 0.3%, AdenoidCystic Carcinoma 0.3%. 3. Radiologic findings by histologic types as follows; a) Squamous cell carcinoma commonlypresent as collapse(51.8%) peripheral mass (40.8%), pneumonitis(37.2%), hilar involvement(34.8%), and in singleabnormality, peripheral mass (44.4%). b) Small cell carcinoma commonly present as hilar involvement(78.1%),mediastinal wideing or mass (53.4%) and in single abnormality, hilar involvement(58.3%). c) Large cell carciomacommonly present as hilar involvement(50%) pneumonia(46.7%), collapse (40%), peripheral mass(36.7%) and in singleabnormality, large peripheral mass (33.3%). d) Bronchogenic Adenocarcinoma commonly present as peripheralmass(44.1%), collapse (41.2%), pleural effusion (35.2%) and in single abnormality, peripheral mass(50%). e)Solitary peripheral mass commonly present as lobulation(48%) and spiculated margin (51%), but no specific findingsby histologic types. Cavitary formation was most common in Squamous cell carcinoma.
