Osteoporosis causes a decrease in bone mineral density. To overcome the decrease in fixation strength, a variety of techniques and devices have been developed, including cement augmentation of pedicle screws. Polymethyl methacrylate (PMMA), is commonly known as bone cement, and is widely used for implant fixation in various orthopaedic and spine surgery. In general, PMMA augmentation of pedicle screws is simple and safe if performed with technical precautions. PMMA is a safe agent, but it may rarely lead to significant foreign body reactions. In this report, we present a patient who developed bone cement-related epidural space foreign body granuloma

BACKGROUND: The pediatric CPR is rather uncommon practice than adult CPR in emergency room. Therefore, few interest and studies were focused in pediatric CPR. The object of this study is to make an analysis about pediatric CPR performed within hospital setting. METHOD: From January 1. 1990 to December 31. 1996, a total of 59 patients, less than 15-year-old, who received cardiopulmonary resuscitation were subject of this study. The study was done retrospective chart analysis for sex, age, weight, the place of cardiac arrest, initial EKG rhythms, endotracheal tube size, the causes of arrest, CPR time, ROSC, the amount and types of CPR drugs used during resuscitation. Wilcoxon rank sum test and chi2 test were used to compare the dose of drugs during CPR in each group. RESULTS: There were no statistical difference between ROSC and non-ROSC group in place of arrest, initial EKG rhythms, CPR time, dosage of CPR drugs. CONCLUSION: The uniform reporting guideline of pediatric advanced life support should be used for future pediatric CPR study, such as Utstein style guideline in pediatric CPR.

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.

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.

Multiple endocrine neoplasi~a type 3 is a rare, heritable or sporadic, multiple neoplastic disorder that is charracterized by thyroid medullary careinoma, pheochromocytoma, multiple mucosal neuroma, and marfanoid habitus. The most important disorder of the syndrome is mucosal neuroma that is an early diagnostic sign of multiple endocrine neoplasia type 3. Early diagnosis of MEN type 3 determines prognosis of the disease. We present a case of multiple endocrine neoplasia type 3 of the sporadic pattern in a 27-year-old man who had typical medullary thyroid carcinoma, mucosal neuroma, marfanoid habitus, and megacolon.

BACKGROUND: Although the precise pathogenesis of the Behçet's disease is not yet undertween the severity of Behçet's disease and the serum cytokine level. development of cytokine research has made it possible to find out if there is an association between the severity of Behçet's syndrome and the serum cytokine level. OBJECTIVE: Our purpose was to elucidate whether the immunopathological mechanism is associated with the serum tumor necrosis factor (TNF) and interleukin-1β (I1,1β) which are predominantly produced by monocytes/macrophages, and mterleukm-6 (IL-6). METHOD: Sixty seven patients of Behçet's disease and ten healthy adults as a control group were studied. Serum TNF and IL-6 levels were detected by enzyme immunoassay and serum IL-lβ levels by radioimmunoassay. RESULTS: There were no statistically significant differences in the serum levels of TNF, IL-1β, TL-6 compared with the control group. CONCLUSION: These data suggest that the immunopathological reactions of the Behçet's disease are not associated with a monocyte/macrophage dependent mechanism, possibly due to other immunocompetent cells.

Intraspinal neurenteric cysts are rare congenital lesions that results from abnormal separation of germ layers in the third week of embryonic development, which may cause spinal compression. Although, the diagnosis of neurenteric cyst was very difficult prior to operation, MRI has proven to be a useful imaging modality in detection, localization and characterization of intraspinal neurenteric cysts. We recently experienced intraspinal neurenteric cyst in two patients who presented with progerssive quadriparesis. Myelography, CT myelography and MRI were taken and complete excision was performed. The MRI findings are presented and the literature is reviewed.
