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.

Diverticulum is considered as common lesion involving any gastrointestinal tract from the pharynx to therectum. We reviewed 5806 cases of upper GI series and 801 cases of Barium enema during the period from Jan. 1978to Dec. 1981 in the Departement of Radiology, school of medicine, JeonBug National University Hospital to analizediverticula of the entire GI tract. The results are follows : 1. Roetgen examination of 5806 esophagus, stomachs,duodenums and small bowels, and 801 colons during the past four years: diverticular of esophagus, 60 cases(1.0%);diverticula of stomach, 42 cases (0.7%); diverticula of duodenum, 358 cases (6.2%); diverticula of small bowel,20( 0.3%); diverticula of the colon, 26 cases (3.2%). The location of diverticula inorder of frequency wasduodenum, colon, esophagus, stomach, and small bowel. 2. the most common site of diverticula of each GI tract wasfollows : diverticula of the esophagus, middle portion (84.7%); diverticula of stomach, the cardia(59.5%);diverticula of the duodenum, second portion(81.3%); diverticula of small bowel, the jejunum(96.4%) especially thelarger percentage were observed at the upper jejunum near the ligament of Treitz; diverticula of the colon, rightsided colon(80.8%), the cecum and ascending colon(57.1%) 3. Diverticula may occur at any age. The majority ofdiverticula of the entire GI tract were observed over 40 years of age. Especialy in diverticula of duodenum andcolon, thir frequency increase with age. 4. Duodenal diverticula were observed more frequently in womanthan in manbut in diverticula of the esophagus, stomach, small bowel, and colon, male was more frequently affected. 5. Thesize of diverticula of entire GI tract was variable. The majoprity of diverticula of the esophagus, stomach,duodenum and small bowel were intermediate size (10-49 mm). Diverticula of the colon were usually smaller than 10mm. 6. Multiplicity of diverticula of entire GI tract was 16.2% of 506 cases. In diverticula of esophagus,stomach, duodenum and small bowel, single lesion was more frequently found. on the other hand, the majority ofdiverticula of the colon were found as multiple lesion(69.2%).

This report is a clinical analysis and comparative study with previous report of bronchial asthma at National Medical Center on bronchial asthma in children who were admitted to the MP dept. of national Medical Center from January 1987 to December 1990. The results of the study were as follows: 1) The out-break ratio of bronchial asthma is 3.7% of hospitalized children which is no change that about 4% since 1980. 2) The children under 6 years of ge was 62.7% which among under 3 years was 33.1%. The rate of under 3 year children is increased as previous study. 3) The out-break of bronchial asthma was most common in September and October and so peak incidence was noted in fall and duration of hospitalization was most 2 week. 4) Familial allergic history was positive in 54.6% and bronchial asthma was most common. The presence of allergic past history was 52.2%) and atopic dermatitis was most common 5) Eosinophilia was found in 80.8% and elevated IgE was also in 61.6% of bronchial asthma. 6) We could get positive results of IgE RAST and skin test: D. pteronyssinus, D. farinae, Houst dust. 7) The most frequent findigs of the chest radiograph were within normal limits. 8) The clinical improvement rate of bronchial asthma is 52.5%.

Cow milk allergy can be defined as an adverse immunologic reactions to cow milk protein. The term is often mistakenly applied to other causes of milk intolerence, such as lactase deficiency and galactosemia, which must be differenciated and excluded. We have experienced 10 children of cow milk allergy at neonatal onset who had suffered from G-I symtoms, such as diarrhea, irritability, weight loss, vomiting and abdominal distension. One half of this patients had family history of allergic diseas. All patients have positive specific IgE RAST to cow's milk protein, milk elimination test and milk challenge test. Brest milk feeding and soy bean formula feeding and soy bean formula feeding have started after diagnosis and then gastrointestinal symtoms and signs of all patients are improved but other allergic diseases are combined in 5 children.
