OBJECTIVE: This study was designed to define the Korean norm values for the Ricketts analysis. METHODS: In this longitudinal study, lateral cephalograms of 31 subjects with normal occlusion were taken biennially from ages 9-19 years. Cephalometric measurements were performed. Parameters for which the 10-year change did not exceed one standard deviation were defined as unchanged. The means and standard deviations for the measured parameters were determined for each age group. RESULTS: No significant changes in growth were observed in the molar relationship, incisor overjet, incisor overbite, mandibular incisor extrusion, interincisor angle, lower incisor tip (B1) to A point-Pogonion (A-PO) plane, upper incisor tip (A1) to A-PO plane, B1 inclination to A-PO, A1 inclination to A-PO, B1 inclination to Frankfurt plane (FH), convexity, lower facial height, facial axis, maxillary depth, maxillary height, palatal plane to FH, cranial deflection, ramus Xi position, or porion location. Continual changes over the 10 years of growth were observed in the maxillary first molar distal position to pterygoid true vertical plane, facial depth, mandibular plane to FH, anterior cranial length, mandibular arc, and corpus length. CONCLUSIONS: Clinicians can apply the Korean norms at age 9 as determined in this study when using the Ricketts analysis. The patient's age at the beginning of treatment and their sex should be taken into consideration when drawing visual treatment objectives.

Most proximal humeral fractures respond satisfactorily to conservative treatment. It is only the occasional displaced fracture or fracture-dislocation that demaads special treatment. The purpose of this study is to analysis the results of closed and open reduction of displaced proximal humeral fractures according to Neers classification. Fifty-two cases of these fractures, followed up more than five months, are presented. 1. The average age of patients was 40. I years. 2. The fractures were classified according to Neers method. Nearly half (48.1%) of the cases were one-part fractures. Next, two-part fractures rated 42.3%, while three-part fractures, only one (l.9%). 3. Among the total 52 patients, 42 cases(80.8%) were treated conservatively and 10 were operated. We performed surgical operations in seven cases among 22 two-part fractures, aix were reduced with Kirschner wires and one treated with Kirschner wire and staple. The average age of these seven cases was 26. 6 years and the resulta were good except one. 4. The results of these patients were evaluated by the Neers criteria. Of 52 caaes, 40 had good results, five, fair, and the remaining seven poor results. Twenty-three cases (92%) in 25(100%) one-part fractures were good and 17 cases (77.3%) in 22 (100%) two-part fractures were also good. In three-part and four-part fractures the results were all poor.

Type 2 diabetes is characterized by insulin resistance, and ENPP1 plays an important role in insulin resistance. We investigated the association of the ENPP1 K121Q polymorphism with both diabetes and obesity (body mass index [BMI]) in Korean male workers. The study design was case-control. Subjects were 1,945 male workers (type 2 diabetes, 195; non-diabetes, 1,750) of nuclear power plants who received examinations from March to October in 2004. We collected venous blood samples under fasting (> or =8 hr) conditions, calculated BMI by height and weight, and assessed relevant biochemical factors. The results of this study demonstrated that the ENPP1 121Q genotype (KQ+QQ types) was not associated with type 2 diabetes (odds ratios [OR], 0.854; 95% confidence interval [CI], 0.571-1.278) or obesity (OR, 0.933; 95% CI, 0.731-1.190). In addition, the frequency of the Q allele was not related to type 2 diabetes (OR, 0.911; 95% CI, 0.630-1.319) or obesity (OR, 0.962; 95% CI, 0.767-1.205). We concluded that the ENPP1 121Q allele is not a critical determinant for either diabetes or obesity in Korean males. The discordance between the results of this study and those derived from studies of Dominican, South Asian, Caucasian, Finnish, and French populations might be due to differences in genetic backgrounds between these populations.
