BACKGROUND AND OBJECTIVES: Reports suggest that Vitamin D deficiency (VDD) is common and is a general health challenge worldwide and at high altitude in particular. AIM: The objectives were to explore Vitamin D status, to examine the association of VDD and clinically detected scoliosis, and to find a cutoff point of Vitamin D level predicting clinical scoliosis in Abha City (high-altitude area). METHODS: A nested case–control design was conducted among a screened population of 417 male adolescents from intermediate and secondary schools in Abha City, Southwest Saudi Arabia. From the surveyed adolescents, 62 cases with clinically detected scoliosis and 205 age-matched controls without scoliosis were selected. For both groups, serum level of 25-hydroxyvitamin D was assessed by standardized technique. RESULTS: More than two-thirds (68.5%) of male adolescents suffered from VDD (<25 nmol/L). The risk of clinical scoliosis was significantly higher among adolescents with VDD compared to those without deficiency (grade adjusted odds ratio = 6.88, 95% CI: 2.63–17.99). Receiver operating characteristic curve analysis showed acceptable discriminative ability of serum Vitamin D (area under the curve = 0.702) to predict scoliosis at a threshold value of ≤20.2 nmol/L. CONCLUSIONS: Overall levels of Vitamin D in the study adolescents suggest a high prevalence of VDD at high-altitude area in Southwest Saudi Arabia. There is evidence for a positive association between VDD and clinically detected scoliosis. A threshold cutoff value of 20.2 nmol/L has been identified to predict clinically detected scoliosis. The role of possible preventive effect of Vitamin D supplementation should be considered by school health authorities.

Thistudy was designed to estimate the carrier rate of beta-haemolytic streptococci among 972 primary-school boys in a high-altitude area of Saudi Arabia, and its association with social class, crowding index and body mass index, and also to determine the seasonal variation of infection. A carrier rate of 13.1% for beta-haemolytic streptococci was detected. The carrier rate was significantly higher in spring than in winter. The association between streptococcal infection and social class, crowding index, or body mass index was statistically not significant. The low prevalence of streptococcal infection might be attributed to the high altitude but further studies are needed to determine whether this is the case

Gloydius strauchi is a venomous pit viper, which is known from Sichuan, Eastern Xizang, Qinghai, Ningxia, and Shaanxi provinces. Here I report a new, genetically verified record of G. strauchi from a high-altitude area of Dêgê County, Garzê Tibetan Autonomous Prefecture, Sichuan Province, and provide information on a mild envenomation case of that species’ bite.

President Park faced a leadership crisis after revelations that she relied on a confidant with no official position for key decision-making in state affairs. Heavy industry met with serious financial difficulties, and a strong anti-corruption law was enacted. North Korea tested more nuclear weapons and missiles. Controversy over the deployment of Terminal High Altitude Area Defense strained South Korea’s relations with China.
