A clinical observation in 8 cases of multiple laminectomies under the age of 16 years who had been followed for more than 3 years was carried out to analyze deformities and its results of treatment, and the following results were obtained. 1. Spinal deformities were developed in 5 cases-4 kyphosis and 1 lordosis. 2. The kyphosis was developed in 1 case at cervical spine, 1 at thoracic, 1 at thoracolumbar junction and 1 at lumbar, and the lordosis was developed in 1 case at lumbar spine. 3. Anterior interbody fusion was carried out on two cases of kyphosis who had severe pain and neurological symptoms and posterolateral spinal fusion was carried out on one case of lumbar lordosis, with satisfactory results in all cases. 4. Since the incidence of spinal deformities following multiple laminectomies in children is high, laminectomy should be performed only when it is definitely indicated, and when it is done, damage to the posterior complex should be minimized. 5. For the prevention and treatment of the spinal deformities, brace or close observation should be necessary postoperatively, and spinal fusion should be performed in increasing or severe deformities.

we report a case of elastosis perforans serpiginosa associated with pseudoxanthoma e1asticurn on t:he neck of 27-year-old male patient. The lesions showecl erythematous scaly hyperkeratotic papules forming serpiginous pattern on yellowish elevated plaques. A skin biopsy specimen from the neck lesion revealed dense accurmulations of coarse elastic fibers partly cngulfed by epithelium in the papillary dcrrnis and increase cif short, irregulary clumped and degenerated clastic fibers in the middermis. On funduscopic exarnination, angioid streak is noted around the optic disk.

We messured delayed cutaneous hypersensitivity reactions by Multitest CMI Kit. Total 209 normal adults ranging in age from 17 to 55 year(male 106, female 103) were tested. The results were obtained as follows ; 1. Sum of average diameter of positive antigens wss 20.7mm in male and 15.6mm in female. 2. Number of positive antigens was 3.9 in male and 3.4 in female. 3. Rate of anergy was 1.4%(0.9% in male, 1.9% in female). 4. The rate of subjects below warning score(below 10mm in male, below 5mm in female) was 2.8% in male and 5.8% in female. 5. Antigen with the highest response was tuberculin in both sex(male 95.3%, female 89.3%) and antigen with the lowest response was trichophyton(22.5%). 6. Aversge score of positive response of every antigens was highest in tuberculin at both sex(male 2.8mm, female 2,6mm) 7. Average score of total antigens with positive response was 5.5mm in male and 4.6mm in female. 8. The rate of false positive reaction to 70% W/V glycerine was 1.4% totally.

Hypercalcluria is well recognized as an important factory in the cause of idiopathic calcium stone disease. Absorptive hypercalciuria and renal hypercalciuria constitutes two major forms of idiopathic hypercalciuria. It is now suggested that renal prostaglandins influence internal hemodynamics and tubular electrolyte excretion, so determine the renal handling of calcium. It is generally believed that urinary c-AMP which comes from renal tubular cells in response to parathyroid hormone stimulation may have an effect calcium reabsorption in distal convoluted tubules. We performed the study to evaluate the significance of urinary calcium, PGE2 and c-AMP in stone formation. Urinary sodium, calcium, PGE2 and c-AMP were measured in 23 in-patients with urolithiasis under the usual diet. The results obtained were summarized as follows: l. 24-hour urinary Na was 120.6+/-49.7mEq/day(mean S.D), 24-hour Ca 202.8+/-68.3 mg/day, Urinary PGE2 625.6+-h 386.9pq/ml and Urinary c-AMP l2.9+/-10.2 nmol/mg creatinine. 2. There was high correlation between urinary. PGE2 level and urinary Na level(r =0.95, <0.005 by paired t-test). 3. There was high correlation between urinary PGE2 level and urinary Ca level(r=0.87, p< 0.005). 4. Urinary Ca level has no significant correlation with urinary c-AMF level(r=0.63, p<0.05).

Posterior urethral valve is the most common obstructive abnormality in male children affecting both Kidneys and likely arise from maldevelopment of the mesonephric duct. We report a case of posterior urethral valve in 4 year old male child with brief review of literature.

Kasabach-Merritt syndrome is the association of thrombocytopenia, disorder of coagulation, spontaneous bleeding and enlargement of a hemangima or extensive hemangiomatosis, which can be often life threatening. We experienced a three years-old girl with suddenly enlarging hemangioma of right cheek, complicated by severe thrombocytopenia, consumptive coagulopathy and hemorrhagic cystitis. Generalized petechia and ecchymosis were noted on the overlying skin of hemangioma, trunk and extremities. But the study of MRI and angiography, hypevascular was located within the right masseter muscle extending to temporalis muscle and anterior to parotid gland. So selective embolization with PVA (polyvinyl alcohol) was performed through the distal branch of internal maxillary artery and facial artery. She was medicated with oral corticosterioid for 3 weeks. After embolizationn, blood flow to hemangioma and facial swelling were markedly decreased. Patient was followed up for 7 years and she showed normal contour of face and no bleeding diathesis.

STATEMENT OF PROBLEM: Zirconia-based restorations have the common technical complication of delamination, or porcelain chipping, from the zirconia core. Thus the shear bond strength between the zirconia core and the veneering porcelain requires investigation in order to facilitate the material's clinical use. PURPOSE: The purpose of this study was to evaluate the bonding strength of the porcelain veneer to the zirconia core and to other various metal alloys (high noble metal alloy and base metal alloy). MATERIAL AND METHODS: 15 rectangular (4x4x9mm) specimens each of zirconia (Cercon), base metal alloy (Tillite), high noble metal alloy (Degudent H) were fabricated for the shear bond strength test. The veneering porcelain recommended by the manufacturer for each type of material was fired to the core in thickness of 3mm. After firing, the specimens were embedded in the PTFE mold, placed on a mounting jig, and subjected to shear force in a universal testing machine. Load was applied at a crosshead speed of 0.5mm/min until fracture. The average shear strength (MPa) was analyzed with the one-way ANOVA and the Tukey's test (alpha= .05). The fractured specimens were examined using SEM and EDX to determine the failure pattern. RESULTS: The mean shear strength (+/- SD) in MPa was 25.43 (+/- 3.12) in the zirconia group, 35.87 (+/- 4.23) in the base metal group, 38.00 (+/- 5.23) in the high noble metal group. The ANOVA showed a significant difference among groups, and the Tukey's test presented a significant difference between the zirconia group and the metal group. Microscopic examination showed that the failure primarily occurred near the interface with the residual veneering porcelain remaining on the core. CONCLUSION: There was a significant difference between the metal ceramic and zirconia ceramic group in shear bond strength. There was no significant difference between the base metal alloy and the high noble metal alloy.
