Pigmented vitreal cyst is a benign and uncommon entity with uncertain etiology. A floating intravitreal material was incidentally noticed in a 44-year-old man. Visual acuity was 1.2 and intraocular pressure 16 millimeters of mercury in both eyes. All other ophthalmic examination were normal. On posterior segment examination, a free-floating, brownish, round cyst of about two disc diameter in size was demonstrated in the inferior vitreous cavity of the left eye without any other abnormalities. During the follow-up examination for thirty months, the shape, size, color, and location of the cyst was not changed with the same visual acuity and IOP. Pigmented vitreal cyst is benign with no change for a long time, and then generally need no special treatment unless it blocks visual axis

CHAP syndorme consists of choreoathetosis, orofacial dyskinesia, affective change, hypotonia, and pseudobulbar signs. CHAP syndrome was firstly des- cribed with onset 1 to 7 days after induced profound hypothermia and complete circulatory arrest for con- genital heart lesion repair. Since then, only a few cases have been reported until now. Case We report a patient who demonstrated all of the elements of the CHAP syndrome in severe cachexic state. Brain SPECT(99mTC-ECD) shows decreased perfusion in left fronto-parieto-temporal lobe. Comments The pathogenesis of CHAP syndrome is obscure. However our case led us to suggest that more essential component pre- disposing to the CHAP syndrome is hypoxia rather than hypothermia. Furthermore, it seems to be related with circulatory insufficiency in extrapyramidal nervous systems.

To evaluate the influence of intraoperative irradiation on the healing of jejunal anastomosis, an experimentalstudy was undertaken using a total of 150 rats. The bursting pressure of the normal jejunum was obtained in groupI. Group II was subjected to resection and anastomosis, and group III was irradiated on the anastomosed jejunumwith a single dose of 1,000 rads. Healing process was evaluated by measuring bursting pressure of the anastomosedjejunum on each postoperative day from 2nd to 14th, and on 21 th day. Bursting pressure was tested by inflatingthe loop of gut with water, and bursting sites were observed. The resuls obtained are summarized as follows; 1.The bursting pressure of the anastomosed jejunum retained normal strength by the 7th postoperative day in thenonirradiated group, whereas by the 11th postoperative day in the irradiated group. 2. Irradiation caused delay inthe healing of anastomosis of the jejunum until the 10th postoperative day; but after then, there was nosignificant difference in bursting pressure between both groups. 3. In the jejunal segments with normal strength,bursting occurred exclusively at the non-anastomotic site in both groups; Bursting started along the mesentericborder in the non-irradiated group, whereas rupture usually occurred on the antimesenteric border in theirradiated group. in the jejunal segments with subnormal strength, bursting usually started on the mesentericborder of the anastomotic site in both groups. The results indicate that intraoperative irradiation with a singledose of 1,000 rads causes no harmful effect on the healing of anastomosis of the jejunum in rats. Therefore, thisstudy suggests the possibility of more effective clinical application of intraoperative irradiation.

Purpose: Genu valgum in Legg-Calve-Perthes disease (LCPD) is not a known complication. We investigated whether this valgus tendency is a complication of femoral varus osteotomy (FVO) or the sequela of the disease process itself, and what are the related factors. Materials and Methods: 35 patients treated by FVO and 38 by abduction orthosis (AO) were selected for this study. Only those patients with unilateral involvement, fragmentation stage, Catterall Group III or IV, and who were followed-up to full skeletal maturity were included in the study. We measured mechanical axis deviation percentage and hip-knee-ankle angle for femorotibial alignment, and mechanical lateral distal femoral angle and medial proximal tibial angle (mMPTA) for knee orientation on teleoroentgenograms and compared the affected and normal limbs. Results: All measurements, excluding the mMPTA, demonstrated a tendency of relative genu valgum versus the opposite normal limbs. This tendency was observed in both groups. There was no statistically significant difference between the two groups. Conclusion: Genu valgum occurred in 66% to 70% of the LCPD patients. Four factors were found to be significantly correlated with valgus shift: increased medial bowing of the femoral neck, decreased acetabulum head index, coxa magna, and limb shortening. Multivariate regression analysis identified limb shortening as the factor most responsible for valgus shift.

Preretinal hemorrhage, which is located between the retina and vitreous face and is commonly developed on the macula, causes impaired central vision and if it persists, it may cause complications, such as epimacular membrane. A 49-year-old male who had dry type of age-related macular degeneration in both eyes and had an oval shaped premacular hemorrhage of unknown etiology in his left eye. We applied Q-switched Nd:YAG laser on membrane anterior to preretinal hemorrhage and ruptured it. Preretinal hemorrage was drained to inferior vitreous cavity and his central vision was rapidly improved.

PURPOSE: To evaluate the extent of lesion by using ultrasound biomicroscopy in eyelid tumor. METHODS: We retrospectively analyzed 17 patients with eyelid tumor, who had undergone preoperative ultrasound biomicroscopy to access the extent of the lesion and the depth of involvement, excision and biopsy. These data were compared to the histopathologic findings. RESULTS: On ultrasound biomicroscopic examination, the eyelid tumor showed greater homogeneous hypoechoic density or heterogenous echo density than that of the surrounding tissue, leading to identifying the lateral margin of the lesion and depth of involvement. The mean maximum thickness of the lesion measured by ultrasound biomicroscopy was 2.26 +/- 0.49 mm and that of the histopathologic depth was 2.22 +/- 0.56 mm. Linear regression demonstrated that lesion depth measured by ultrasound biomicroscopy was correlated with histopathologic depth. CONCLUSIONS: In eyelid tumor, ultrasound biomicroscopy is helpful in assessing the extent of the lesion and the depth of involvement preoperatively, and in obtaining good postoperative results.

OBJECTIVE: To evaluate factor XII deficiency in patients with recurrent spontaneous abortion and its relation to aPTT. MATERIAL AND METHOD: Factor XII was analyzed by clotting method. RESULTS: Of 70 patients with recurrent spontaneous abortion, there were 35 cases of factor XII deficiency. Among them, there were only 3 cases of prolonged aPTT. CONCLUSIONS: It is still unclear whether factor XII deficiency is related to recurrent spontaneous abortion. Molecular approaches should be used to understand further the causal relationship. But based on this result, in the workup of patients with recurrent spontaneous abortion, factor XII should be included. aPTT is not likely to represent the abnormality of factor XII.

PURPOSE: To know the proportional contribution of causative factors to the femoral shortening in Legg-Calve-Perthes disease. MATERIALS AND METHODS: In twenty piglets, 4 to 5 weeks old, vascular supply to the capital femoral epiphysis was interrupted by ligating the femoral neck containing the epiphyseal artery. RESULTS: Mean femoral shortening in piglets sacrificed at 4 weeks after devascularization was 7.4 mm. In detail, the shortening was 2.5 mm (34%) in the epiphysis and 4.9 mm (66%) in the neck and diaphysis. Mean femoral shortening in piglets sacrificed at 8 weeks after operation was 12.1 mm. The distribution of shortening was 4.6 mm (38%) in the epiphysis and 7.5 mm (62%) in the neck and diaphysis. Mean femoral shortening in piglets sacrificed at 20 weeks after operation was 20.7 mm. The distribution of shortening was 4.0 mm (19%) in the epiphysis and 16.7 mm (81%) in the neck and diaphysis. CONCLUSION: We determined the proportional contribution to the residual shortening according to the causative factors.
