The tricuspid valve is not a simple but a complex structure, tricuspid valve complex. This complex is composed of tricuspid orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There are flew articles about these structures. The authors studied tricuspid valve complex in 53 cases of normal korean adults, such as circumference of tricuspid annulus, the maximum diameter of the tricuspid orifice, height and breadth of the cusps, including commissures, the ratio of rough to clear zone, the number of scallops of posterior cusp, the number, length and pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.

Thirteen patients were operated for cubital tunnel syndrome and followed for an average of 26 months postoperatively. Ten patients had a history of relevant trauma and three patients had degenerative osteoarthritis of the elbow. The average duration of symptoms was 18 months (range, 2 to 96 months). Diagnosis was made by physical examination, electromyography and nerve conduction study. Among these, nerve conduction study was found to be the most valuable diagnostic method for the patients with atypical clinical findings. Most of the operations were performed by anterior transposition of the ulnar nerve. At the most recent follow-up, the result was excellent in two patients, good in eight, and fair in three; thus ten patients(77%) showed satisfactory results. The rating system for ulnar neuropathy based on sensory, motor dysfunction and pain was useful for evaluating the operative results. The postoperative gain of score for pain and sensory function were larger than that of motor function. Factors known to influence the result of the operation (age, duration of symptom, history of trauma, method of operation) did not effect the outcome in this study. For successful operation, the ulnar nerve must be thoroughly examined, all possible levels of compression must be released and new foci of compression must be created.

Phylloides tumor is very similar to giant fibroadenoma in that they have benign appearance in breast radiologic image. Fibroadenoma has no malignant potential, but phylloides tumor is locally recurrent, invasive and may occasionally metastasize. It thus appears that evaluation of the differential point of the two tumor groups by radiologic study is very important. We retrospectively compared sonographic find;.ngs of 6 cases of phylloides tumor with those of 4 cases of fibroadenoma, which proved pathologically in Ye mgnam University Hospital from 1984 to 1986. The mean age of the patients were 31.8 years old(from 14 to 41 years old) in phylloides tumor and 28.8 years old (from 17 to 40 years old) in giant fibroadenoma, respectively. The viewpoints of this analysis were size, shape and contour of the masses, internal echo pattern, posterior enhancement, and especially the existence of peripheral cyst or septal band echo. We found that diffenentiation of these two tumors by sonography was difficult. But peripheral cyst was found only in phylloides tumor and septal band echo was found largely in giant fibroadenoma. Although the existence of peripheral cyst or septal band echo in the breast mass was not pathognomonic findings, we suggest that the existence of septal band echo is preferential finding to fibroadenoma, and peripheral cyst is preferential finding to phylloides tumor.

The occurrence of fistulous tract between the thoracic subarachnoid space and the pleural cavity due to injury is uncommon. The one was developed after traffic accident and treated by surgical repair of the fistula : The other was post-operative complication of costotransversectomy for T2 sympathectomy. The complication was realized by the surgeon who was aware of the small leakage of cerebrospinal fluid from the dura propria of the T2 nerve root at the time of surgery. Intermittent pleural punctures for drainage and semisitting position were followed by spontaneous closure of the fistula. These cases were reported so that the uncommon condition might be added to the differential diagnosis of pleural effusion.

The pulsed laser lithotripsy has been used in the treatment of urinary calculi. We treated 153 patients of stones, via the pulsed dye laser(Technomed Pulsolith) with 7.5 and 6.5 F. rigid ureteroscope between January 1992 and January 1995. Stones were in bladder(4 cases), upper ureter(17), mid ureter(31) and lower ureter(101). The laser lithotripsies were applied for impacted stones and relatively large stones(more than 6 mm) The success rates according to location were 47%(8/17) in upper ureter, 77%(24/31)in middle ureter, 95%(96/101)in lower ureter and 100%(4/4) in bladder and mean success rate was 86% (132/153). There were 21 failures due to upward migration(9 cases), poor visual field(7), laser resistant stone(3) and malfunction of laser(2). Complications were showed in 28 cases that were gross hematuria(16 cases), ureteral perforation(6), fever(4) and ileus(2), but most of them might be related to ureteroscopy rather than laser, and all of them were resolved with conservative management. So laser lithotripsy is safe and effective method of middle and lower ureteral calculi, and upward migration of stones, the major cause of failure may be resolved by use of extracorporeal shock wave lithotripsy and flexible ureteroscope.

Recurrent episode of meningitis in infants and children frequently constitute a frustrating and distressing, both in determination of course and treatment. The authors are reporting a infected case of congenital dermal sinus with dermoid cyst in the subarachnoid space of cauda equina and conus medullaris which was cured after complete removal of cyst and sinus tract.
