We report a case of hereditary trichilemmal cyst with proliferating trichilemmal tumor in a 64-year-oid man, who has generalized 157, variable sized firm cutaneous nodules for 40 years. The cystic nodules are chiefly located on the scalp and trunk which showed characteristic histopathologieal findings of trichilemmal cyst and proliferating trichilemmal tumors. His son also has multiple trichilemmal cysts and his mother seems to have had clinically similar lesions. The patient and his son were treated with surgical excision and therapeutic trial of oral isotretinoin for 2 months. Isotretionoin was ineffective in the patient, but the lesions of his son were decreased in size.

PURPOSE: Neonatal hyperbilirubinemia has benign courses in most cases, but the possibility of toxicity of hyperbilirubinemia required courses examination of every newborn infant to identify the severity of hyperbilirubinemia progress. This study aims to see how the body surface area of newborns influences the decline rate of serum bilirubin level in conventional phototherapy. METHODS: Based on the charts of the Pediatrics Department, Dae-Dong Hospital from January 2003 to December 2006, we analyzed 168 neonates diagnosed as neonatal hyperbilirubinemia (serum bilirubin > or =15 mg/dL) in retrospective way. We excluded newborn infants under 37 weeks of gestation and under 2,500 g birth weight and classified neonates into four groups by the calculation results of body surface area:males above 75 percentile (group A), males below 25 (group B), females above 75 (group C), and females below 25 (group D). RESULTS: Out of 168 samples, the number of group A, B, C, D was 30, 20, 20, 15 respectively. In conventional phototherapy, the mean decline rates of serum bilirubin of group B and D recording 2.09 mg/dL/day and 1.77 mg/dL/day, were significantly faster than those of group A and C recording 1.63 mg/dL/day and 1.41 mg/dL/day (P<0.01). No significant differences were found in different duration of phototherapy between groups below 25 percentile and those above 75 in both genders. CONCLUSION: In conclusion, body surface area influences of infants the decline rate of serum bilirubin level in conventional phototherapy.

Although basic mechanisms of atopic dermatitis remain largely speculative, many studies on pathogenesis suggest the importance of food and inhalent allergens. To evaluate the frequency of food and house dust mite hypersensitivity and differences in this frequency according to ages, we measured the levels of specific IgE antibodies to egg white, egg yolk, milk, soy, and house dust mites in 119 children with atopic dermatitis. The results showed that 53% of patients had positive RAST to any one kind of allergens. The frequency of food and house dust mite hypersensitivity were 34.5%, 30.3 %, respectively. Among allergens, house dust mites and egg white are the most prevalent allergens in all atopic dermatitis patients. The Prevalence of egg white is most common under the age of 2 years, but those of house dust mites are the dust mites are the highest in the ages of 5-12 years. In conclusion, we recommend an egg restriction diet in atopic dermatitis patients who are less than 2 years old when their symptoms do not improve with general skin care.

Palisaded, encapsulated neuroma is characterized clinically by a solitary, slowly-growing and dome-shaped papule or nodule, usually accompanied by telangiectasia on the surface, and histopathologically by an encapsulated nodule in the dermis and the palisading arrangement of nuclei. A 57-year-old female patient presented with a 1cm-sized, solitary nodule on the right ala nasi which had been present for about 5 years. The nodule had a tendency to slow growth and it became a polypoid nodule. Telangiectasia was shown on the surface of the lesion. Histopathlogical findings showed a well-defined and encapsulated nodule in the dermis, composed of spindle cells with basophilic and plump nuclei in a palisading fashion. On immunohistochemical staining, the tumor cells of the nodule were positive for S-100 protein, while the capsule of the nodule was negative for S-100 protein. Epithelial membrane antigens were focally positive only on the capsule of the nodule. We report herein a case of palisaded, encapsulated neuroma, one case of which has been reported in Korea.

PURPOSE: To evaluate the diagnostic value of gross bloody stools as a predictor of intussusception. METHODS: We reviewed 159 cases retrospectively that had an ultrasound examination for diagnosis of intussusception from January 2001 to December 2003 at Ilsin Christian Hospital. We compared each symptom and assessed the diagnostic value of gross bloody stools in the patients with suspected intussusception. RESULTS: Thirty-six of the 159 patients had intussusception. Of 36 patients with intussusception, 19 (52.8%) children were male and 28(77.8%) children were younger than two years. The most common symptom was intermittent abdominal pain or irritability. But its frequency among the intussusception (24.2%) was lower than frequency of gross bloody stools(50.9%). The sensitivity, specificity, positive predictive value(PPV) and negative predictive value(NPV) of gross bloody stools in patients with suspected intussusception were as follows; sensitivity=77.8%(95% CI 60.8-89.9), specificity=78.0%(95% CI 69.7-85.0), PPV=50.9%(95% CI 37.1-64.6), NPV=92.3%(95% CI 85.4-96.6)(Diagnostic accuracy 78.0 %; 95% CI 70.7-84.2). CONCLUSION: It is useful for diagnosis of intussusception to confirm the presence of gross blood in stools.

Diclofenac sodium is a widely used drug for reducing inflammation and pain after cataract, surgery or excirner laser photorefractive keratectomy. However,we could find epithelial defect while using this drug postoperatively. To investigate the toxic effects of diclofenac sodium, we cultured corneal epithelial cells and tissues, then exposed them to various concentratiotration of drugs and measured the cell number and expanding area from. the original corneal tissue. In cases of cell culture, the cell number was counted at 24, 48, and 72 hours` exposure to l2.5, 25, 50, and 100 ug/ml solution of diclofenac sodium and at. 5 days after two minute exposure to 0. I and 0.2% solution. The cell number was reduced significantly at 50ug/ml (72 hrs later) , 100ug/ml(48 or 72 hrs later) and 0.1, 0.2% of solution than that of the control group. In tissue culture, we exposed the epithelial tissue to the same condition of cell culture. In long duration exposure conditions, the size of the epithelium grown from the tissues was smaller than that in the control group, especially at the dosage of 50 and 100ug/ml. In short duratio(2 minutes) exposure conditions, no significant difference from the control group was found. In conclusion, diclofenac sodium has some suppressive effects on the growth and migration of the rabbit corneal epithelium and its postoperative high dose or frequent instillation might injure the corneal epithelial cells.

Rupture of the sinuses of Valsalva is not common in childhood. It is frequently associated with other heart disease, most commonly with VSD. It is classified into four types, anatomically. The symptoms are differentiated as acute, gradual progression, and unruptured aneurysm. We experienced 2 cases of rupture of the sinuses of Valsala, which were corrected completely after operation. The patients were 14 year old boy with his chief complaint of dyspnea and chest pain, and an 11 year old girl with chief complaint of exertional dyspnea.

STATEMENT OF PROBLEM: Unlike screw-retention type, fixture-abutment retention in Locking taper connection depends on frictional force so it has possibility of abutment to sink. PURPOSE: In this study, Bicon(R) Implant System, one of the conical internal connection implant system, was used with applying loading force to the abutments connected to the fixture. Then the amount of sinking was measured. MATERIAL AND METHODS: 10 Bicon(R) implant fixtures were used. First, the abutment was connected to the fixture with finger force. Then it was tapped with a mallet for 3 times and loads of 20 kg corresponding to masticatory force using loading application instrument were applied successively. The abutment state, slightly connected to the fixture without pressure was considered as a reference length, and every new abutment length was measured after each load's step was added. The amount of abutment sinking (mm) was gained by subtracting the length of abutment-fixture under each loading condition from reference length. RESULTS: It was evident, that the amount of abutment sinking in Bicon(R) Implant System increased as loads were added. When loads of 20 kg were applied more than 5 - 7 times, sinking stopped at 0.45 +/- 0.09 mm. CONCLUSION: Even though locking taper connection type implant shows good adaption to occlusal force, it has potential for abutment sinking as loads are given. When locking taper connection type implant is used, satisfactory loads are recommended for precise abutment location.
