Cobb syndrome is a rare neurocutaneous angiomatosis characterized by a vascular skin nevus associated with a spinal cord angioma of the same metamere. A 14-year-old girl had an asymptomatic large cutaneous hemangioma distributed from the TI dermatome downward to the L3 dermatome since birth and complained of a gait disturbance and urination difficulty for 1 year. A biopsy specimen in the skin lesion revealed the findings of capillary hemangioma. From C7 downward to L4 posterior epidural hemangioma composed of arteriovenous and cavernous components was diagnosed by radiological examination and surgical exploration. Because of very extensive cord hemangioma, only partial removal of the tumor at T11, T12 and L1 level was performed and postoperatively she was transferred to a special facility for rehabilitative therapy.

BACKGROUND: Intermittent rhythmic delta activity (IRDA) is classified as a nonspecific abnormal EEG pattern. IRDA is clinically associated with alteration of consciousness, hydrocephalus, cerebral edema, deep midline lesions, subcortical lesions, and tumors of the posterior fossa and the third ventricle. Frontal IRDA(FIRDA) is usually seen in patients over age 15 years, whereas occipital IRDA(OIRDA) occurs mainly in children. We have investigated the clinical feature and significance of IRDA in children. SUBJECTS AND METHODS: We retrospectively reviewed the medical records of 36 children with IRDA of EEG concerning diagnosis, neurologic examination, classification of epilepsy, and CT & MRI findings. RESULTS: 1) The location of the IRDA was frontal(FIRDA) in 11 of 36(30.5%), occipital(OIRDA) in 20 of 36(55.6%) and mixed in 5 of 36(13.9%) patients. 2) Thirty of 36(83.3%) have epilepsy (including 1 each with MELAS and tuberous sclerosis), 4 of 36(11.1%) have migraine and 2 of 36(11.1%) patients have meningitis. 3) Sixteen of 30(53.3%) have partial or partial with secondary generalized seizure, 10 of 30(33.3%) have generalized seizure and 4 of 30(13.3%) patients with epilepsy have absence seizure. 4) Neuroimaging studies (CT or MRI scan) were performed in 27 cases. Among 27 cases of studies, 6 cases(22.2%) were abnormal including; two cases of infections, and each case of infarction, venous angioma, arachnoid cyst, cortical atrophy, and tuberous sclerosis, respectively. CONCLUSIONS: IRDA may be considered an epileptiform pattern in childhood and FIRDA is frequently seen in children than previous reports.

To analyse the age of onset, etiologic microorganisms, clinical manifestations, managements and genetic variation of chromic granulomatous disease, the authors reviewed four patients who were diagnosed as CGD at Department of Pediatrics, Seoul National Univesity Children's Hospital. They were siblings in relationship-two of them were brothers, the others were brother-sister. @ES The results were as follows; 1) Initial manifestations developed within 1 year old, and lymphadenopathy associated with BCG vaccination was the most common. 2) In culture study of micro-organism, catalase positive microorganisms such as Staphylococcus aureus, Serratia marcescens, Coagulase (-) Staphylococcus, Enterococcus, Proleus vulgaris, Klebsiella pneumoniae, E. coli and fungus such as Candida albicans were isolated. In 2 cases, culture study revealed no growth. 3) Fever, lymphadenopathy, hepatomegaly, suppurative dermatitis and pneumonia were the most common manifestations. In most of cases, antituberculous medications were administered under the impression of tuberculosis without response. 4) Immunologic screening tests including B-cell system, T-cell system, and complement system were within normal limit except NBT test. 5) In spite of severe infections, NBT scores of all the cases were less than those of controls. Liver biopsies of 3 cases showed granuloma formation with characteristic yellow brown pigment-laden macrophages.

The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.

Iatrogenically developed immunosuppression-associated Kaposis sarcoma is the result of immunosuppressive therapy after an organ transplantation, particularly after a renal transplantation. Since the advent of powerful immunosuppressive agents such as cyclosporine, recently the incidence of Kaposis sarcoma has been increased. In addition to immunosuppression, other factors, such as genetic predisposition, environmental and geographic factors, and oncogenic viruses, may play a role in the pathogenesis of this tumor. Ilerein we report a case of Keposis sarcoma with multiple organ involvement of the skin, lung, small intestine and mesenteric lymph node in a renal allograft recipient who received cyclosporine and prednisolone. Reduction of the dosage of immunosuppressant for 1 month resulted in improvement of the cutaneous lesions.

Primary peptic ulcer disease in not known to be the result of underlying illness or trauma. These are most frequently duodenal or prepyloric. Since clinical features of peptic ulcer in children can easily be confused with many other disorders, the diagnosis is usually made when one of the more dramatic presentations, such as perforation, bleeding and obstruction. Recently, we experienced 2 cases of duodenal obstruction due to peptic ulcer in children. So, we report it with review of references.

PURPOSE: The objective of this study was to evaluate fracture strength of collarless metal-ceramic FPDs according to their metal coping designs. MATERIALS AND METHODS: Four different facial margin design groups were investigated. Group A was a coping with a thin facial metal collar, group B was a collarless coping with its facial metal to the shoulder, group C was a collarless coping with its facial metal 1 mm short of the shoulder, and group D was a collarless coping with its facial metal 2 mm short of the shoulder. Fifteen 3-unit collarless metal-ceramic FPDs were fabricated in each group. Finished FPDs were cemented to PBT (Polybutylene terephthalate) dies with resin cement. The fracture strength test was carried out using universal testing machine (Instron 4465, Instron Co., Norwood MA, USA) at a cross head speed of 0.5 mm/min. Aluminum foil folded to about 1 mm of thickness was inserted between the plunger tip and the incisal edge of the pontic. Vertical load was applied until catastrophic porcelain fracture occurred. RESULTS: The greater the bulk of unsupported facial shoulder porcelain was, the lower the fracture strength became. However, there were no significant differences between experimental groups (P > .05). CONCLUSION: All groups of collarless metal-ceramic FPDs had higher fracture strength than maximum incisive biting force. Modified collarless metal-ceramic FPD can be an alternative to all-ceramic FPDs in clinical situations.
