A previous study has shown that dental practitioners in Benghazi believed that the less prevention-oriented education system is one of the barriers to applying preventive dentistry. ⋯ This study highlighted that the currently implemented undergraduate education programme in Benghazi dental school does not provide dentists with the required attitude and skills to fulfil their role in providing preventive-oriented health services.

In this communication, we argue about the need for an extensive investigation of the relationship between body fatness and fat distribution and experimental pain to explore the factors that might contribute to the increased prevalence of pain conditions in obese individuals.

The sympathetic activation is considered to be the main mechanism involved in the development of cardiovascular diseases in obstructive sleep apnea (OSA). The heart rate variability (HRV) analysis represents a non-invasive tool allowing the study of the autonomic nervous system. The impairment of HRV parameters in OSA has been documented. However, only a few studies tackled the dynamics of the autonomic nervous system during sleep in patients having OSA. ⋯ OSA affects sympathovagal modulation during sleep, and this impact has been correlated to the severity of the disease. The mean RR seemed to be a better index allowing the sympathovagal balance appreciation during the night in OSA.

Road traffic injuries (RTIs) are a major public health concern in Libya. In the light of the armed conflict in Libya that broke out on February 2011 and the subsequent instability, the rate and pattern of RTIs was studied. ⋯ There were fewer RTIs during the conflict period; however, those that occurred had higher morbidity and mortality. The profile of an RTI victims also changed to an increased prominence of young males and motorcyclists. Further research is required to propose and analyze possible interventions.

Diabetic complications and lipid peroxidation are known to have a close association. Lipid peroxidation commonly occurs at sites exposed to ischaemia, but distant organs and tissues also get damaged during ischaemia/reperfusion (I/R). Some of these targets are vital organs, such as the lung, liver, and kidney; the lung is the most frequently affected. The aim of our study was to investigate the effects of dexmedetomidine on I/R damage in lung tissue and on the oxidant/anti-oxidant system in diabetic rats. ⋯ Our results confirm that dexmedetomidine has protective effects against the lung damage resulting from I/R in diabetic rats. Future studies conducted to evaluate the effects of the use of dexmedetomidine on damage to various organs following different I/R durations may help understanding possible protective effects of dexmedetomidine and underlying mechanisms in tissue damage related to I/R injury.
