We studied thirteen, all male, patients who had trans-scaphoid perilunar dislocation(stage I, 5 cases) and dislocation of lunate(stage IV, 8 cases). Age of patient was ranged from 25 years to 49 years(avr. 36 years)and the most common cause of injury was fall down(6 cases, 46%). Seven acute cases, diagnosed and treated within 3 weeks from injury, were treated by open reduction and K-wire fixation(5 cases), and K-wire fixation and bone graft(1 case) and Herbert screw for fracture of scaphoid(1 case). Six chronic cases diagnosed and treated after 3 weeks from injury were treated by open reduction and K-wire fixation(1 case), K-wire fixation and bone graft(1 case), removal of lunate(2 cases), and arthroplasty using muscle after removal of lunate(2 cases). Thirteen cases were followed up for average 33 months(from 13 months to 81 months). Grip power was evaluated as excellent or good in 8 cases and fair in 5 cases. Range of motion of wrist joint was decreased 21 degrees in flexion, 22 degrees in extension, 4 degrees in ulnar deviation, and 5 degrees in radial deviation of wrist joint, compared with uninjured side. Carpal height and carpal height ratio were decreased to 33.1 and 0.51, compared with normal 35.8(p=0.001) and 0.55(P < 0.001), respectively. Between 2 groups of acute and chronic cases, no significant differences were noted in carpal height or carpal height ratio. The surgical treatment of perilunar fracture-dislocation has not simple option, therefore, we would recommend the early diagnosis and exact anatomical reduction.

An unusual case of intraspinal peripheral neuroepithelioma arising from the cauda equina is reported. The patient, a 21-year old female, suffered from low back pain with radiation to the posterior aspect of both legs. Myelographic, computed tomographic scan and magnetic resonance imaging studies of lumbosacral spine showed the intradural extramedullary mass lesion on the L3-S1 level which was excised surgically, but recurred rapidly. It could be diagnosed by the histopathologic findings. The postoperative radiotherapy and chemotherapy were administered. We report this rare case with review of the literatures.

The frequency of stab wounds is gradually increasing and patients with stab wounds visit the hospital through the emergency room. Management options for patients with stab wound include mandatory exploration and selective observation, but recently many authors have emphasized the importance of selective conservation with development of diagnostic procedure and controversy still exists concerning the management of patients with stab wounds. We retrospectively analysed the clinical data of 78 patients with stab wounds who visited the emergency room of St. Paul's Hospital over 5 years from January 1 1992 to December 31 1996. The following results were obtained. 1) The most prevalent age group were the twenties & the thirties(58.9% of patient) and then most patients were of young age. The male to female ratio was 2.9: 1. 2) Most injuries occurred at night between 8p.m. and 4a.m.(61.5%) and during September injuries were most frequent. 3) The most common causes of stab wound were fighting(55.1%) followed by suicide (21.8%), then accidents including traffic accidents(16.7%) and robbery(6.4%). 4) The instruments most commonly used were knives(53.8%) and broken glass(28.2%). 5) Half of patients were drunk from alcohol and in 3 cases from an antipsychotic drug. 6) In 11 cases(14.1%), there were multiple wound sites and in 8 cases(10.3%) superficial wounds into subcutaneous fatty tissue. 7) According to stab wound sites, the extremities were wounded in 36 cases(46.2%), chest in 21 cases(26.9%), abdomen in 15 cases(19.2%) and neck in 7 cases(9.0%). 8) Emergency explorations were performed in 43 cases(55.1%) under general or regional anesthesia, which included neck in 4 cases(9.3%), chest in 3 cases(7.0%), abdomen in 11 cases(25.6%) and extremity in 25 cases(58.1%). In exploratory laparotomy, negative exploration rate was 18.2%. 9) Death occurred in 2 cases(2.6%). One died due to sepsis with multiple colon perforation and the other due to hypovolemic shock with Superior Vena Cava injury.

Lymphatic vessels are routes for leukocyte migration and fluid drainage. In addition to their passive roles in migration of leukocytes, increasing evidence indicates their active roles in immune regulation. Tissue inflammation rapidly induces lymphatic endothelial cell proliferation and chemokine production, thereby resulting in lymphangiogenesis. Furthermore, lymphatic endothelial cells induce T cell tolerance through various mechanisms. In this review, we focus on the current knowledge on how inflammatory cytokines affect lymphangiogenesis and the roles of lymphatic vessels in modulating immune responses.

A number of noninvasive technics have been advocated as reflecting left ventricular performance. These methods include systolic time intervals, echocardiography and imaging of the left ventricular chamber with radionuclides during systole and diastole. Radionuclide evaluation of left ventricular function by means of the gamma camera and gating currently appears to be the most reliable noninvasive method for approximating angiographic evaluation of left ventricular performance. Utilizing the radionuclide angiography, we measured the left ventricular function in 19 normal healthy control, 60 patients with coronary artery diseases 7 patients with dilated cardiomyopathy, 5 patients with hypertension. 1) Left ventricular ejection fraction decreased in 12 patients with anterior myocardial infarction (39.9+/-11.6%), 17 patients with inferior myocardial infarction (49.9+/-8.4%) and 7 patients with dilated cardiomyopathy (19.0+/-5.8%), and there was a statistically significant difference compared with 19 normal control group (63.5+/-8.2%)(p<0.005). However there were no statistically significant difference between normal control group, patients with hypertension (58.8+/-7.6%) and patients with angina pectoris (60.1+/-6.5%). 2) Left ventricular ejection fraction decreased in both anterior and inferior myocardial infarction, and there was a statisically significant difference between both groups (p<0.01). All 13 patients with acute myocardial infarction had abnormal LVEF (40.5+/-9.1%) whcih was significantly lower than that of 16 patients with old myolardial infarction (50.1+/-10.5%)(p<0.01).

PURPOSE: To evaluate tlne significance of vaginal air seen on CT scan in preoperative staging of uterine cervical carcinoma. METHODS AND MATERIALS: A comparison was made between CT findings of vaginal air and true vaginal involvement status in 85 patients with uterine cervical carcinoma. CT findings were analyzed in terms of the presence or absence of vaginal air, number of CT slices in which vaginal air was seen, shape of vaginal air, and relation of vaginal airto cervical mass. RESULTS: Vaginal air was present in 35 patients and was absent in 50. Although the mere presence of vaginal air or multiplicity of CT slices showing vaginal air did not signify the presence of vaginal involvement, vaginal air with irregular margin or vaginal air adjacent to uterine cervical mass was suggestive of vaginal involvement. CONCELUSION: These observation of vaginal air in interpreting CT may be helpful in the preoperative staging of uterine cervical carcinoma.
