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.

Twenty one cases of adult tibial shaft fractures were fixed with flexible intramedullary nails at the Department of Orthopedic Surgery, Kang Nam General Hospital. The results are summerized as follows; l. Average healing time was 17 weeks. No case of nonunion was experienced. 2. As the operation was perfomed by closed method under fluoroscopic control, reduction of operation time is a major advantage. 3. Fixation was usually strong enough to allow immediate weightbearing and mobilization of the adjacent joints without external immobilization. 4. Three cases of delayed union and 2 cases of rotational malunion were experienced, but shortening and angulation were not so severe as to affect overall functional results. 5. In conclusion, Ender nailing is considered to be a valuable method in treating tibial shaft fractures. Even in cases with multiple injuries and in selected open cases, Ender nailing can be a saft procedure.

Angiosarcoma is a rare primary malignancy occurring anywhere in the body, but most often in the skin, liver or breast. The radiological findings of angiosarcoma of the breast have rarely been reported. We encountered a case in which the condition involved a 32-year-old woman in whom mammography revealed a obscuved-marginated and lobular-shaped high-density lesion, and ultrasonography demonstrated an ovalshaped, microlobular-marginated, inhomogenous hypoechoic mass which metastasized to the whole body after surgery. We report the radiological findings of this case of angiosarcoma of the breast, and review the literature.

PURPOSE: We report on a novel method and outcomes of laparoscopic gastric tubing with pyloromyotomy. METHODS: The abdominal procedure includes laparoscopic gastric mobilization, celiac axis lymph node dissection, formation of the gastric tube, and pyloromyotomy. Between January 2009 and April 2013, our minimally invasive esophagectomy (MIE) was performed on 54 patients with esophageal cancer. The short-term outcomes, including postoperative complications, were analyzed. RESULTS: There were no cases of conversion to open surgery. Of 54 patients, 52 patients had squamous cell carcinoma (SCC) and two had adenocarcinoma. The total operative time was 349.8+/-77.4 minutes, of which 90.6+/-27.6 minutes was required for the abdominal procedure. The mean estimated operative blood loss during the abdominal procedure was 40.0+/-355.5 ml. The postoperative complication rate was 24.1%; three patients died of pneumonia. CONCLUSION: Laparoscopic gastric tubing with pyloromyotomy is a feasible and safe treatm ent option for patients with esophageal cancer.

A discription is given of 24 patients with the benigen focal amyotrophy; Nineteen had upper-limb and five had lower-limb involvement. The characteristic clinca! Features were insidious onset in the second and third decades, male predominance. Sporadic occurance, wasting and weakness confined to one limb, relatively good prognosis and absence of involvement of the cranial nerves, cerebrum, brainstem, and sensory syetem. The nerve conduction studies, electromyographic pattems, somatosensory evoked potential studies, and CTMM or MR findings suggested anterior horn cell disorders. In nine cases we were able to demonstrate focal atrophy in the lower cervical cord limited to the ipsilateral anterior horn region, and two cases segmental cord atrophy in the lower cervical cord in MR or CTMM studies. The benign focal amyotrophy, for which no causes been described, is benign and self-limiting, unlike most motor neuron diseases.

PURPOSE: To describe the angiographic findings of patients with recurrent hemoptysis after bronchial artery embolization (BAE) according to the point at which relapse occurred. MATERIALS AND METHODS: From 125 patients who underwent BAE due to hemoptysis between 1996 and 2000, we selected 18 of 23 who underwent additional BAE due to recurrent bleeding after initial BAE . Depending on the point at which relapse occurred, they were divided into two groups (I and II, according to whether additional BAE was performed within two weeks of initial BAE or more than two weeks after this). We retrospectively compared the two groups in terms of angiographic findings, number of embolized arteries, and character of feeding arteries at initial and additional BAE. RESULTS: Nine patients in group I (additional BAE: n=10) and nine in group II (additional BAE: n=13) were admitted for recurrent hemoptysis within two weeks of initial BAE and more than two weeks after this, respectively. In group I(n=29) and II(n=31), angiography demonstrated two direct and 27 indirect, and two direct and 29 indirect signs of hemorrhage, respectively. No statistically significant differences were observed (x2=0.005, p=0.945). Among the embolized feeder ressels in group I (n=30) there were 20 bronchial artery and 10 non bronchial systemic collaterals, while for group II(n=35), the corresponding totals were 21 and 14. Again, no statistically significant differences were encountered(x2=0.308; p=0.579). In group I, feeders were newly developed in one case(10%), previously embolized in five(50%), and missed in four(40%), while in group two the corresponding figures were none, twelve(92.3%), and one(7.7%). No significant differences were noted, though the incidence of previously embolized feeders in Group II was very high (x2=5.383, p=0.068). CONCLUSION: Among patients in whom hemoptysis after BAE recurred at different times, the angiographic findings and number of embolized arteries were not significantly different, but differences in the nature of the feeder were noted. Patients in whom hemoptysis recurred more than two weeks after BAE showed more recanalization of previously embolized feeders than those in whom there was recurrence within two weeks.
