The incidence of deacclimatization to high altitude syndrome (DAHAS) prevailed up to 80% in highland troops, and 100% in manual workers, and severe DAHAS could significantly affects patients' health, work and life. So it is imperative to develop effective prevention and treatment measures for DAHAS. The present review analyzes effective prophylactic and therapeutic measures against DAHAS, implemented at our hospital.

OBJECTIVETo analysis deacclimatization symptom scores of 159 youth from Karakoram and Tibet Ali area, and provide the basis for the development of relevant prevention and control measures.

METHODSUsing the method of epidemiological symptoms questionnaire, 18 symptoms of 190 youth who returned to the plain area from the different plateau were investigated. The symptom scores of different altitude, age, the time of staying, different units, continuous or intermittent stage and education were surveyed.

RESULTSDeacclimatization symptom scores among 5,000 meter groups were significantly higher than those of 4,300 meter and 3,700 meter group (P < 0.05, P < 0.01). There was no significant difference between the 4,300 meter group and the 3,700 meter group (P > 0.05). There were significant differences among the stayed personnel (different age, position, unit, education, time, continuous or intermittent) (P < 0.01). There was significant difference between the continuous defended the group and intermittent group (P < 0.01).

CONCLUSIONDeacclimatization symptom scores were related to the plateau exposure time, altitude, workload, plateau continued exposure. The older, the longer exposure, the higher altitude, the greater workload at plateau were showed higher deacclimatization symptom score.

The present study was carried out to explore the Cordyceps species and other entomopathogenic fungal flora around Kathmandu Valley and a few high altitude locations of Nepal. In this paper, we report eight Cordyceps species as new to Nepal: C. gracilis, C. ishikariensis, C. liangshanensis, C. martialis, C. militaris, C. pruinosa, C. sphecocephala and C. tricentri. We also mention a few allied genera such as Beauveria, Hirsutella and Paecilomyces from Nepal. Further collections from different ecological regions of Nepal will show the richness of entomopathogenic fungal floral diversity of Nepal.

PURPOSE: The authors studied the change according to altitude in the intraocular pressure (IOP) of rabbit models after intravitreal gas injection. METHODS: We injected C3F8 gas (pure gas, 0.4 cc) into the vitreous cavity in six pairs of rabbits. The six rabbits were divided into the Fast group and the Slow group. After 3 days, we measured the rabbits' IOPs at five different check points along the Young-Dong Expressway while traveling in a car. RESULTS: The IOPs of the Fast and the Slow groups at each check point, respectively, were 11.83+/-2.14, 13.00+/-3.69 (p=0.518) in Won-ju (130 m), 20.00+/-2.28, 21.17+/-2.14 (p=0.382) in Hoeng-seong (560 m), 28.00+/-2.60, 24.83+/-1.94 (p=0.038) in Pyeong-chang (580 m), 30.83+/-3.60, 26.67+/-1.63 (p=0.027) in Dae-gwall-yeong (805 m) and 9.83+/-1.17, 10.83+/-2.14 (p=0.338) in Kang-neung (70 m). We found that IOP increased with increased altitude in both groups. The IOP of the Fast group was significantly higher than that of the Slow group at the Pyeong-chang and Dae-gwall-yeong check points. CONCLUSIONS: We observed that IOP increased during car travel as altitude increased. In addition, we found that the rate of ascent was a risk factor for increased IOP. Therefore, it is important to inform patients with intraocular gas to avoid fast ascents during car travel and to ascend slowly after IOP has stabilized.

OBJECTIVE: To investigate the altitude, immigration and suicide rates association in Turkey. METHODS: Suicide and immigration rates of 81 provinces and their elevation data were obtained. RESULTS: There were not significant correlations between country elevation, immigration and mean suicide rate. CONCLUSION: The findings of this study points out that altitude related hypoxia and suicide association may not be generalized and further research will be needed to clarify the effects of altitude on suicide rates.
