AIM: In Turkey, studies about frequency of carbon monoxide (CO) poisoning are rare. In this study, it is aimed to determine the frequency of the CO poisoning cases occurring all around the country. METHOD: This study was planned as a descriptive study covering Turkey in general as stage. In this study, the CO poisoning case records of Ministry of Health Treat Services General Directorate in 2010 have been examined. The distribution of cases among regions-provinces, mortality rates, types of CO sources, seasonal and monthly dispersions have been examined. RESULTS: According to the records, totally 10.154 cases of CO poisoning were detected in Turkey in 2010 and only 39 of them were ended with death. It is determined that the frequency of cases is 0,0137% (approximately 14 in every 100.000) and mortality rate is about 5 in every 10 million. Poisoning cases have been occurred mostly in Marmara Region (3.426 cases, 33,7%). When it is evaluated in regard to the population, cases are mostly seen in Kilis (0,1998%). As of mortality rates, Bursa has the most number of cases ending with death (18 cases). CONCLUSION: Compared to studies in other countries, according to our data, Turkey was faced with more frequent cases of CO poisoning. The number of cases has increased, especially during the winter months. [TAF Prev Med Bull 2011; 10(5.000): 587-592

We suggest that CO exposure duration, history of loss of consciousness, time to HBO therapy, and the number of HBO therapy session affect neuropsychological symptom levels and occurrence of attention and behavioral problems.

Jet pilots had aortic enlargement as they became older in contrast to the NJP group. Although the aortic diameters were not within the critical ranges in the JP group, these results could suggest that flight-related stresses might result in acute aortic syndromes in the long term.

CRVO related CRAO should be regarded as a rare complication of exposure to high altitude and HBO seems to be the treatment of choice of high altitude related co-occurence of CRVO and CRAO in the late period.
