Two cases of traumatic bilateral anterior and posterior dislocation of hip are reported. Dislocations were developed by a traffic accident as a passenger injury in truck. In both cases, the fractued femoral heads appeared posteriorly dislocated on x-ray examination and one of them was removed through posterior approach. Primary arthroplasty for operated hip was not attempted because the patient was young and the defect seemed to be unrelated to weight bearing surface. Extreme rarity of its incidence and curious uncertain mechanism of injury urge to report these cases.

The diagnostic importance of finding an appendicolith in the plain x-ray of the abdomen has been well documented. However, most of the papers so far published have stressed x-ray findings of the preoperative abdomenin acute appendicitis. In the present study we have attempted to correlate incidences of appendicoliths insurgical specimen and plain x-ray of the abdomen. The materials were 37 surgical specimens of the appendix removed for acute appendicits at St. Mary's Hospital, St. Paul's Hospital, Kang Nam Hospital, Holy Family Hospital and Our Lady of Mercy Hospital of Catholic Medical College during the period of 6 months from August 1980. Each surgical specimen was subjected to soft tissue radiography to detect calcified appendicolith. Then the preoperative x-raysof abdomen were retrospectroscopically analysed for the presence of radiographically demonstrable appendicoliths.Our study revealed that in as many as 32% of 37 surgical specimens one or more calcified appendicoliths were demonstrated radiographically whereas only one of these was identified as such in the preoperative x-ray film ofthe abdomen. Such a great discrepancy between the incidences of appendicoliths in the surgical specimen andpreoperative x-ray films of the abdomen are ascribed to (1) relative smallness of appendicoliths (87% of the stones measured less than 1cm in diameter in radiographs of surgical specimen in our series), (2) overlapping of these small stones on the right iliac bone and (3) underpenetrating of the iliac bone area in x-ray films of theabdomen. For improving detctability of appendicoliths therefore it is recommended that the technique of radiography of plain abdomen should be such that a small appendicolity overlying the iliac bone can be brought outof trabecular shadows.

Schilder’s disease is a rare sporadic demyelinating disease of the brain. We report a girl with Schilder’s disease who had undergone Kasai operation for biliary atresia. The patient presented with acute right hemiparesis. Brain magnetic resonance imaging (MRI) showed a single large tumefactive white matter lesion. A diagnosis of Schilder’s disease was based on clinical features and MRI findings. The patient showed dramatic clinical improvement and significant regression of the lesion in response to high-dose intravenous methyl prednisone, and remained free of relapse of other neurologic problems during the 3-year follow-up.

PURPOSE: This study was retrospectively conducted to evaluate the clinical results of consecutive 167 myopic eyes of 117 patients undergoing laser in situ keratomileusis(LASIK) for myopia with either of the two excimer lasers, which differ in the method of laser delivery: flying spot scanning versus broad beam. METHODS: According to the laser used, the treated eyes were divided into two groups: Group I, 84 eyes of 58 patients with LaserScan LSX(R)(Lasersight Inc., USA); Group II, 83 eyes of 59 patients with OmniMed II(R)(Summit, USA). Each patient had been followed up for more than 6 months after surgery. Only single procedure outcomes were included. Mean preoperative spherical equivalents(SE) were -5.67+/-1.79 D(range:-1.50~-9.75 D) in group I and -6.40+/-1.79 D(range:-3.50~-9.75 D) in group II. RESULTS: At postoperative 6 months, mean uncorrected visual acuity increased to 0.94 in group I and 0.88 in group II. Uncorrected visual acuity of 20/40 or better occurred in 100% of group I and 96.4% of group II, and of 20/20 or better, in 57.2% and 48.2%, respectively. No eye in either group lost more than 1 line of best-corrected visual acuity. Mean SEs at postoperative 6 months were -0.28+/-0.50 D in group I and -0.55+/-0.60 D in group II(P<0.05). Manifest SEs were within +/-1.00 D in 97.6% of group I and 84.3% of group II, and +/-0.50 D in 73.8% and 60.2%, respectively. Intra- or postoperative complications were subconjunctival hemorrhage(4 eyes, group I; 5 eyes, group II), Sands of Sahara syndrome(7 eyes, group I; 5 eyes, group II), epithelial ingrowth(1 eye, group II only) and infectious keratitis(1 eye, group II only). No case had a central island or irregular astigmatism postoperatively. CONCLUSIONS: Our study suggests that LASIK using the LaserScan LSX(R)excimer effectively reduces myopia compared with OmniMed II(R). However, its predictability decreased as the attempted correction increased. LASIK for myopia less than -10 D with the LaserScan LSX(R)provided satisfactory refractive results that compare well with other reports in the literature.

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.

Loss of best corrected visual acuity(BCVA)is a landmark of safety, as one of important complications of refractive surgery. To evaluate causes of 2 lines or more loss of BCVA after laser in situ keratomileusis(LASIK), 206 eyes of 139 patients, who had undergone LASIK and had been followed up for 6 months or more, were included in this study. During the follow-up, nineteen eyes(9.2%, 19/206)showed 2 lines or more loss of BCVA postoperatively. The causes of BCVA were irregular astigmatism(15 eyes, 7.3%), retinal complications(3 eyes, 1.5%), and infectious keratitis(1 eye, 0.5%). All irregular astigmatisms had occured within 1 month postoperatively and 13 eyes of all 15 eyes spontaneously recovered after postoperative 3 months. The persistent loss of BCVA occurred in 5 eyes(2.4%, 5/206). Three cases of all 5 persistent losses of BCVA were due to retinal complications. In conclusion, our results suggest that the most common cause of loss of BCVA after LASIK is irregular astigmatism. Irregular astigmatism is a temporary situation which has a tendancy of spontaneous recovery. Thus careful observation is recommended in irregular astigmatism after LASIK. The retinal complications of LASIK may lead to permanent loss of BCVA. Therefore it is needed to examine preoperative fundus closely and to explain possible postoperative complicaitons to the patients and their family.
