The Association between Height and Mental Health in Korean Male Adolescents

BACKGROUND: The growth of Korean adolescents' average height has slowed over the past 10 years. The objective of this study was to investigate the association between height and mental health in Korean male adolescents.METHODS: This study used data from the 2015 Korea Youth Risk Behavior Web-based Survey (34,152 male school students). The male adolescents were divided into the below-average height and above-average height groups according to age. The association between height and mental health was analyzed by multivariate logistic regression.RESULTS: The above-average height group had significantly higher subjective health (P=0.003) and significantly lower depression than the belowaverage height group (P=0.031). In multivariate logistic regression, the odds ratio of subjective health wass 1.13 (P=0.043), but no significant difference in subjective happiness, depression, stress and suicidal ideation (P>0.05) at both group.CONCLUSION: It was confirmed that height is associated with subjective health in Korean male adolescents.

Salmonella Typhi Osteomyelitis in a Non-sickle Cell Patient: Three Cases Report / 대한정형외과학회잡지

Salmonella osteomyelitis is uncommon and it often develops in patients with sickle cell anemia and other hemoglobinopathy. Especially, osteomyelitis caused Salmonella typhi in a nonsickle cell patients is a very rare event. We report three cases with review of literature.

Hydroxyapatite-Coated Primary Total Hip Arthroplasty: Minimum two year clinical and roentgenographic analysis / 대한정형외과학회잡지

Plasma sprayed coating of the hydroxyapatite(HA) are biocompatible and may contribute to the early fixation of total joint prosthesis. We studied 64 hips(58 patients) who had hydroxyapatite coated primary total hip arthroplasty during the period from January 1992 to June 1993 about clinical and radiological result prospectively. The components have been followed for a minimum of 26 months and an average 31 months. Harris hip score averaged 92 at most recent follow up intervals. At the last follow up, the pain in 7 cases(11%) respectively and only slightly to mild in mostly. Although thigh pain has been occurred in 7 cases(11%), all patients had not trouble in daily activity. In radiological evaluation, there was a rapid and good endosteal bone formation of implants with bone apposition on the Gruen zone 2 and 6 of HA coating area. No radiolucent line formation was detected around HA coated area. In acetabular component, the endosteal bone formation was found in 12 cases and the radiolucent line was occurred in 4 cases. No revision were done for the femoral and acetabular component. The result of the study indicate that this hydroxyapatite coated component can provide satisfactory clinical and radiological result. Further prospective follow up is necessary to determine whether the favorable early result of this implant are maintained over longer period.
