Purpose: To evaluate the results of percutaneous lateral release and arthroscopic medial plication for patients with recurrent patella dislocation. Materials and Methods: This study includes the thirty-one cases of patients who have had a surgical operation from March 2001 to March 2008. All the patients had recurrent patella dislocation after trauma history. The average age was 24.2 years old and the average follow up was 47.4 months (minimum 24 months). Results: The preoperative congruence angle, lateral patellofemoral angle, Lysholm score was $24.8^{\circ}$, $-6.2^{\circ}$, 75 points on average respectively. However, the postoperative congruence angle, lateral patellofemoral angle, Lysholm score was improved to normal range: $-2.8^{\circ}$, $10.2^{\circ}$, 95 points on average. Five cases showed the recurrent dislocation after operation. Among them, three cases showed femoral trochlear dysplasia. Conclusion: Percutaneous lateral release and arthroscopic medial plication showed satisfactory results for recurrent patella dislocation with low complication rate. However, in cases with femoral trochlear dysplasia, another surgical treatment may be considered.

Oligodontia is defined as the congenital absence of six or more teeth in dentition, excluding the third molars. The prevalence of congenital missing teeth is about 1.6 to 9.6% of population and the prevalence of oligidontia is about 0.08 to 1.1%. The mandibular second premolar is the most frequently absent after the third molar, followed by the maxillary lateral incisor and upper second premolar. Females seem to be affected slightly more than males. Oligodontia may occur either in isolation, or as a part of a syndrome such as ectodermal dysplasia. Different causes are possible for oligodontia: physical obstruction or distruction of the dental lamina, space limitation, functional abnormalities of the dental epithelium, failure of induction of the underlying mesenchyme, chemotherapy, radiotherapy or genetic factor. Because oligodontia would result in esthetic and functional problems, such as facial asymmetry or occlusal disharmony, early diagnosis from clinical and radiographic examination was necessary. And appropriate treatment plan should be followed. This case report was about oral conditions and treatment of the oligodontia patients who have no specific systemic disease.

Purpose: The aim of this study was to identify the effects of neonatal developmental intervention program (NDT) in promoting motor development and growth and to determine the usefulness of Hammersmith Neonatal Neurological Examination (HNNE) and Neonatal Behavioral Assessment Scale (NBAS) in premature infants. Methods: We performed NDT on selected premature infants (PI, n=42) and compared them with the full term control group (FC, n=20). NDT protocol and development assessment (HNNE, NBAS) were manipulated by the physical therapist in the neonatal intensive care unit. The data of this study were collected prospectively. Results: The PI with GA <34 weeks (VPI) subgroup showed a more use of mechanical ventilator and surfactant, severe bronchopulmonary dysplasia and intraventricular hemorrhage, and patent ductus arteriosus treated surgically than the PI with GA $\geq$34 weeks but less than 37 weeks (LPI) subgroup. The average scores improved significantly in the PI group between the 1st, 2nd, and 3rd assessment by repeated measure (P=0.000). Also, the PI group showed significantly higher total scores and average score at 40 weeks postmenstrual age, P=0.000, respectively than in the FC group. The LPI subgroup showed more weight gain and change in the head circumference between the 1st and 3rd assessment by repeated measure, respectively, P<0.05. The PI group showed no apnea, bradycardia and late sepsis associated with intervention and assessment. Conclusion: The NDT might be a safe and useful intervention to promote motor and growth outcomes in premature infants. Also, the HNNE and NBAS might be safe and useful tools for assessing neurodevelopment in premature infants.

This research focuses on the overall evaluation of tumor protein (p53) and cell growth marker (Ki-67) in their functions as carcinogenic factors in both a HPV-infected group and in a HPV-noninfected group with the precancerous dysplasia of uterine cervix. Histological grades were determined by the H&E staining and the expression level of p53 and Ki-67 were tested by the immunohistochemistry method. The results were as follows. Among the total of 66 cases, p53 (+) was observed in 19 cases (29.0%) from the mild grade group, 22 cases (33.0%) from the moderate grade group, and 19 cases (29.0%) from the severe grade group. The values correlate with the increase of dysplasia intensity in HPV-noninfected group and showed significant correlation (p<0.05), but there were no significant difference from the HPV-infected group. Among a total of 66 cases, the mitotic index of Ki-67 (+) were observed in 19 cases (29.0%) from the mild grade group, 22 cases (33.0%) from the moderate grade group, and 19 cases (29.0%) from the severe grade group. The values were significantly different against dysplasia intensity (p<0.05), but showed no significant difference from HPV infection. After cross comparing the statistical parameters of p53 and ki-67 in their significance, p53 was shown to be statistically significant with Ki-67 while there was no statistically significant difference with Ki-67 (p<0.05). Taken together, tumor protein (p53) and an index of Ki-67 observed in cervical dysplasia and in HPV related dysplasia of cervix uterine did not have any notable significance with HPV infection. The incidence rate of p53, however, had some significant correlation with dysplasia while Ki-67 had no particular statistical significance. As a result, p53 and Ki-67 can be considered as effective diagnostic markers in predicting the disease progression of dysplasia to cervical cancer.

Cemento-ossifying fibroma of the jaws is well circumscribed, generally slow-growing, benign lesions which enlarge in an expansile manner. Clinically it presents as a slowly enlarging lesion commonly in the premolar-molar area of the mandible and only occasionally in the maxilla and other locations. It occurs twice as often in females and primarily in the 20 to 30 year age group. Differential diagnosis should be peformed, preferably with other fibro-osseous lesions such as fibrous dysplasia. A faster growing and more destructive variant of cemento-ossifying fibroma sometimes occurs in patients under age 15 and is termed juvenile (aggressive) ossifying fibroma. Treatment is surgical removal with the extent depending on the size and location of the individual lesion. Recurrence is considered rare. A case involving a 12-year-old male patient with delayed eruption of right mandibular canine is discussed. Following an incisional biopsy, the histopathologic diagnosis established was cemento-ossifying fibroma. After the surgical enucleation of the lesion, no sign of recurrence was detected.

Moyamoya disease is an unusual cerebrovascular disorder characterized by occlusive intimal dysplasia of the distal internal carotid and proximal cerebral arteries as well as other collateral arteries. However, moyamoya diseases are recently being reported as a systemic process. We experienced one case of coronary artery occlusive disease affected by moyamoya disease. The patient was a 35-year-old female, experiencing intermittent NYHA class ll dyspnea and exertional chest pain for 6 months and right paresthesia for 1 month before admission. Cerebral artery angiogram showed abnormal cerebrovascular systems and confirmed moyamoya disease with cerebral infarction of the left frontal lobe. In coronary artery angiogram, left coronary artery was not visualized due to total occlusion of the left main ostium and left coronary blood flow was supplied from normal right coronary artery. CABG was performed with OPCAB. Both internal mammary arteries were used for LAD and LCx. Intraoperative coronary artery findings showed intimal hyperplasia and no definite thrombi, and nondiseased coronary arteries were good and patent. We concluded that this patient's coronary artery disease was affected by moyamoya disease, and moyamoya disease should be evaluated in the extracerebral cardiovascular system.

Tooth anklylosis is defined as the adhesion state of alveolar bone to dentin or cementum. Trauma, disturbed metabolic disease, and congenital disease have been given as etiologic factors. Complications of tooth ankylosis are tipping of the neighboring teeth, space loss, and supraeruption of the opposing teeth. Particularly if dental ankylosis occurs in maxillary incisors of a growing child, the ankylosed tooth can not move vertically with subsequent disturbance in vertical growth of the alveolar process. With an appropriate treatment approach, an esthetic condition must be achieved especially in the maxillary anterior region. In this report, two cases are presented which were treated by the surgical repositioning method. One is treated by alveolar bone distraction osteogenesis which used a tooth-borne type distraction device and the other by single tooth osteotomy.

Congenital Missing Teeth(hypodontia, oligodontia) is the developmental absence of one or more teeth. It has been reported as being the most common anomaly of dental development in human, relatively common in the permanent dentition. In a recent review, Vastardis has quoted incidence ranges of $1.6%{\sim}9.6%$ in the permanent dentition. Brook has quoted a prevalence of $3.5%{\sim}6.5%$ in most populations, with severe hypodontia, defined as the absence of six or more teeth, having a prevalence of $0.3{\sim}0.4%$. The most commonly affected teeth are third molars, followed by maxillary lateral incisor, and second premolars. The etiology is unknown, several hypotheses include trauma, nutritional deficiency, infection, metabolic abnormalities, systemic disease and genetic influence. The multiple congenital missing is commonly associated with specific syndrome or severe systemic abnormalities such as cleft lip & palate and Down's syndrome. These cases present that children have multiple congenital missing teeth in the permanent dentition, without any systemic disease. Management of this condition must be considered orthodontic and prosthodontic treatment comprehensively. In these cases, children were treated by space maintainer or orthodontic appliance and follow-up checked.

In this case, we would like to discuss about the single rooted deciduous mandibular first molar. The deciduous mandibular molar of a five years old boy was shown to have a single root, bilaterally. Ordinarily, the maxilary molars have three roots and the mandibular molars have two roots. However, when the hertwig's epithelial root sheath do not invaginate properly during tooth development, root fusion can occur from the absence of root separation. Molars with fused roots not only have unfavorable crown to root ratio, but also according to many reports, have higher probability of having multiple congenitally missing teeth or dens invaginatus in the maxillary incisors, consequently requiring preventive dental treatment In addition, disorders such as ectodermal dysplasia, syndactyly, clinodactyly, bluish sclera can also be related to this condition. Root fusion is known to be of autosomal recessive inheritance. Up to date, single rooted molars have been reported several times in permanent dentitions but hardly in deciduous dentition, which is the motive for this paper.
