Assessment of Uric Acid Level in the Saliva of Patients with Oral Lichen Planus.

OBJECTIVE: The aim of this study was to evaluate the level of uric acid (UA) in saliva, which is considered to be an antioxidant defense biomarker against oxidative stress in patients with oral lichen planus (OLP). SUBJECTS AND METHODS: In this case-control study, 25 OLP patients were included. The reticular form of OLP was verified by a clinical examination with Wickham striae, and other types (erosive, atrophic, ulcerative) were confirmed by histopathological assessment. Thirty healthy individuals matched for age and gender were selected as the control group. In both groups, the Navazesh technique was used to collect the unstimulated saliva. Then, the amount of UA was measured using a Cobas Mira autoanalyzer with a wavelength of 546 nm. The Student t test was used to analyze the data assuming a significance level at <0.05. RESULTS: Of the 25 patients, the most common type of OLP was erosive (n = 11, 44%), and the most common site of OLP was seen as bilateral in the buccal mucosa (n = 12, 48%). The mean level of salivary UA was significantly lower in the patients with OLP (2.10 ± 0.19 mg/dL) in comparison with the control group (4.80 ± 0.29 mg/dL; p < 0.001). CONCLUSION: In this study, OLP was associated with a decrease in UA levels in the saliva. Salivary UA as a biomarker could be used for monitoring and treating OLP.

Pattern of Alcohol Consumption among Men Consumers in Kerman, Iran.

BACKGROUND: Alcohol consumption is a potential risk factor with acute and chronic health consequences and social impacts, which is more prominent among men. There is no precise statistics on the scope of alcohol consumption in Iran; however, there is some evidences showing an increasing trend, particularly among young generation. In order to evaluate the scope of this issue in Kerman, a large city in the south-east of Iran, this exploratory study was designed to approach a group of people having an experience of alcohol use in 2014. METHODS: Samples were recruited to the study using a snowball sampling. 200 eligible subjects were questioned about the type of alcohol consumed, frequency of use, and other factors associated with alcohol consumption. In order to maximize the validity of responses, data were collected through self-administered questionnaires. FINDINGS: The main alcoholic drinks consumed by individuals were the homemade distillates (46%), wine (22%), beer (14%), distilled spirits (11%), and medical alcohol (7%), respectively. The majority of individuals participating in the study (73%) used mostly homemade drinks; moreover, 63%, 26%, 9%, and 2% of subjects took monthly or less, two to four times a month, two to three times a week, and at least four times a week, respectively. Only 2% of the subjects were heavy consumers of alcoholic beverages. CONCLUSION: Due to the lack of control over homemade alcoholic beverages, its high levels can be a huge potential risk. Furthermore, it seems that both factors of access and price to be very effective in the amount of alcoholics taken by individuals. Therefore, further studies in this area will help to reduce the harm caused by alcohol consumption.
