PURPOSE: Complete fibrovascular ingrowth within the hydroxyapatite ocular implant is necessary for peg drilling which is performed to prevent infection and to provide motility to the ocular prosthesis. We compared planar bone scintigraphy and SPECT for the evaluation of the vascularization within hydroxyapatite ocular implants. MATERIALS AND METHODS: Seventeen patients (M:F=12:5, mean age: 50.4+/-17.5 years) who had received a coralline hydroxyapatite ocular implant after enucleation surgery were enrolled. Patients underwent Tc-99m MDP planar bone and SPECT imaging by dual head gamma camera after their implant surgery (interval: 197+/-81 days). Uptake on planar and SPECT images was graded visually as less than (grade 1), equal to (grade 2), and greater than (grade 3) nasal bridge activity. Quantitative ratio of implanted to non-implanted intraorbital activity was also measured. Vascularization within hydroxyapatite implants was confirmed by slit lamp examination and ocular movement. RESULTS: All but three patients were considered to be vascularized within hydroxyapatite implants. In visual analysis of planar image and SPECT, grade 1 was noted in 9/18 (50%) and 6/18 (33%), respectively. Grade 2 pattern was 7/18 (39%) and 4/18 (22%), and grade 3 pattern was 2/18 (11%) and 8/18 (44%) respectively. When grade 2 or 3 was considered to be positive for vascularization, the sensitivity of planar and SPECT imaging were 60% (9/15) and 80% (12/15), respectively. In 3 patients with incomplete vascularization, both planar and SPECT showed grade 1 uptake. The orbital activity ratios on planar imaging were not significantly different between complete and incomplete vascularization (1.96+/-0.87 vs 1.17+/-0.08, p>0.05), however, it was significantly higher on SPECT in patients with complete vascularization (8.44+/-5.45 vs 2.20+/-0.87, p<0.05). CONCLUSION: In the assessment of fibrovascular ingrowth within ocular implants by Tc-99m MDP bone scintigraphy, SPECT image appears to be more effective than planar scintigraphy.

OBJECTIVE: The objective of this study was to compare results of the macroscopic one-layer vasovasostomy with those of microscopic one-layer vasovasostomy and to analyze the change of semen parameters according to the interval of vasal obstruction. METHOD AND MATERIALS: Between March 1987 and December 1997, we performed 121 vasovasostomies using modified one-layer technique with loupe magnification (macroscopic vasovasostomy) or microscope. Among the 68 could be followed post-operatively, 37 patients were treated by macroscopic technique with loupe, and 31 patients by microscopic technique. We compared rates of anatomical patency (sperm count above than 10x106/ml) and pregnancy of macroscopic vasovasotomy with those of microscopic vasovasostomy. Patency and pregnancy fates according to vasal obstructive interval were also examined. RESULTS: The patency rates of macroscopic and microscopic technique were 86.5% and 87.1%, and pregnancy rates of macroscopic and microscopic technique were 64.9% and 67.7%. There was no statistical significance between these two methods (p>0.05). The pregnancy rates and sperm motility were decreased if more than 10 years had elapsed following vasectomy(p<0.05). CONCLUSION: We found little difference in success rates resulting from macroscopic and microscopic vasovasostomy and the former had the advantage of reduced cost and a lower operator skill level. in post-operative semen analysis, the sperm motility was the most probable factor associated with vasal obstructive interval.

Aplasia cutis congenita is a rare disorder characterized by localized or generalized absence of skin at birth. Group 4 in Friden's classification, which is associated with embryologic malformations including myelomeningocele, encephalomeningocele, omphalocele, gastroschisis. The authors have experienced a case of aplasia cutis congenita of right frontal scalp associated with bony defect, forming encephalocele in a newborn. We reported this case with brief review of literatures.

We report a case of gastro-colic fistula caused by ectopic gastric mucosa developed at transverse colon. Fistula was detected by colonofiberscopy. And fistulous tract was proved by barium enema. Meckel's diverticulum scan finding was similar to that of GI bleeding; e.g. injected radioactivity was secreted into the lumen and moved along the lumen. There was no bleeding. And there was no diverticulum in the colon. Absence of diverticular pouch may explain this unusuaal GI bleeding-like scan finding rather than focal collection of radioactivity, which is typical of ectopic gastric mucosa found in the Meckel's diverticulum. Ectopic gastric mucosa was confirmed by colonfiberscopic biopsy. We suggest GI bleeding-like pictures should be included differential diagnosis of Tc-99m-O4 (ectopic gastric mucosa or Meckel's diverticulum) scan.

Dried specimens of the genus Inocybe collected from mountain areas throughout the Korean country from 1982 to 1998 and preserved in NIAST were investigated. Out of them, Inocybe hystrix were confirmed as an unrecorded species in Korea. In 1991 Lee et al., previously recorded Inocybe kasukayamensis only with its scientific name and korean common name. In this study we report it with full descriptions of morphological characteristics and diagnosis of micro-structures of this species.

Many authors have been reported that the abdominal trauma, especially injury of the liver and spleen, is frequently found with lower rib fractures, below the ninth rib fractures and the incidence was about 20 to 30%. In cases of rib fractures, Intra- abdominal organs may be injured in the higher rib fractures than the ninth because the diaphragm is elevated at the level of filth intercostal space in expiration period and the intra-abdominal lesions are often delayed evaluated due to the pain of the fractures and masked by the other injuries of the head and the extremities. So above reasons, we were often questioned what the level of rib fracture we must evaluate the intra-abdominal injury was? So we investigated 452 patients with rib fractures who visited our emergency medical center from 1995, January to 1996, December and divided into two groups according to the prescience of intra-abdominal organ injuries by each the level of rib fractures. The number of patients with intra-abdominal organ injuries were 75(16.6%) and the most frequently damaged organ was the liver(25 cases, 33.3%). We calculated the statistical values of each level of rib fractures by the Chi-Square method and got a result that the level of rib fracture we must evaluate the intra-abdominal injuries was the sixth rib fracture. Therefore, if we will meet the patients with rib fracture below the sixth, we must have attentions to the intra-abdominal injuries and evaluate the abdomen closely with various diagnostic methods.

We report herein three cases of subcutaneous sarcoidosis without apparent internal lesion. The patients had multiple subcutaneous nodules on the extremities and abdomen. Hyper-gammaglobulinemia, a relative increase of T suppressor cells, and increased serum angiotensin converting enzyme level and skin anergy were observed. Histopathologic findings revealed sarcoidal granulomas involving the subcutaneous fat tissue. The lesions of two cases resolved spontaneously and the other one case required systemic corticosteroid therapy.
