This report describes simultaneous bilateral Legg-Calve-Perthes disease (LCPD) development in four-year-old identical male twins. Moreover, the twins showed head involvement patterns with mirror symmetry. We included a review of the literature on this rare condition and discussed the genetic risks associated with LCPD.

The aim of the present study was to investigate the distribution of periodontally hopeless teeth in patients who had not been treated. Five hundred nineteen teeth of 163 patients who had visited at the Department of Periodontology, Chonbuk National University Hospital during the period from January 1999 to July 2001 were selected as a periodontally hopeless tooth. Selection criteria were as follows: 1) probing pocket depth more than 8mm, 2) tooth mobility of degree III, 3) radiographic bone loss more than 75%. The contralateral tooth to a hopeless tooth (experimental tooth) was designated as a control tooth. Between the experimental and control tooth, differences in probing pocket depth, tooth mobility and amount of radiographic bone loss were examined as well as correlation. The results showed that hopeless teeth were most frequently found in the maxillary first molar position and least frequently in the maxillary canine position. Differences between experimental and control teeth were 2mm in probing depth, 1 degree in tooth mobility, and 20% in amount of bone loss (p<0.01). The periodontal conditions between the experimental and control teeth showed correlation in general, however, statistical significances were found in posterior teeth positions. Within limitations of this study, it can be concluded that local factors may play a role in deterioration of periodontal disease along with symmetrical character of periodontal disease.

Clear cell sarcoma of the kidney (CCSK) is a highly malignant childhood tumor, distinguished from classic Wilms' tumor by its propensity to metastasize to the skeletal system. Authors described a case of CCSK from a 3-year-old boy in the right kidney, showing various histologic features, such as classic, epithelioid, trabecular, neurilemmoma-like, cystic and entrapped collecting tubular pattern. Ultrastructurally epithelial differentiation was absent. Immunohistochemically, none of the intrinsic tumor cells showed positive staining with the antibodies against the keratin, S-100 protein, carcinoembryonic antigen, vimentin, desmin and myoglobin, suggesting primitive mesenchymal cell in origin.

The purpose of tracheotomy is to obtain secure airway for difficult airway management and long-term lung ventilation. Tracheotomy is an invasive procedure with the possibility of severe complications, but it is the last choice for difficult airway management. To perform tracheotomy is difficult in patients with anatomically distorted trachea, screened trachea by mass, fibrosis or adhesion and obesity. We report the experience of successful tracheotomy in the patient of severely distorted airway due to previous surgeries with the aid of the light illumination of fiberoptic bronchoscope.

PURPOSE: The incidence of retinopathy of prematurity(ROP) which is one of the most common cause of childhood blindness has not decreased despite the restricted use of oxygen. There may be other factors responsible for ROP which could not be explained solely by improved survival of very low birth weight infants. We tried to clarify perinatal risk factors that are nrelated to the occurrence of ROP. METHODS: We enrolled 239 infants with gestational ages less than 33 wks or with birth weight less than 1,800 gm who had received ophthalrnologic examination between Jan. 1995 and Dec. 1997. The patients were categorized into two groups,' "No ROP" group as control(n=185) and ROP group as study population(n=54), and we compared the perinatal risk factors between the two. RESULTS: 54(22.6%) out of 239 infants were diagnosed as having ROP. The annual incidence of ROP decreased but the incidence of treated ROP increased. The incidence of ROP decreased with longer gestation and higher birth weight. Mean gestational age was 30.3 weeks in the study group vs 31.0 weeks in the control group, and mean birth weight was 1,390 gm and 1,586 gm, respectively. Significant factors contributing to increased incidence of ROP included: duration of oxygen therapy, ventilator therapy, total parenteral nutrition and hospitalization, frequency of hyperoxia, hypercarbia, and transfusion and respiratory distress syndrome, umbilical artery catheterization, intraventricular hemorrhage, sepsis, bronchopulmonary dysplasia, use of dexamethasone and aminophylline, pneumonia, air leak syndrome, and hyperglycemia. The incidence of ROP and treated ROP was not influenced by the mode of surfactant treatment(prophylactic vs rescue) in RDS patients and the mode of dexamethasone treatment(short vs long) in BPD patients. CONCLUSION: The risk factors for retinopathy of prematurity included gestational age, birth weight and duration of oxygen, as well as other aforementioned perinatal factors. The occurrence of ROP can be decreased by preventing preterm birth, minimizing the use of oxygen, and further morbidity can be prevented by performing proper ophthalmologic examination and doing an appropriate follow-up.
