BACKGROUNDSkin cancer is the most common cancer worldwide; one in every three diagnosed malignancies is a skin cancer. However, skin cancer is rarely reported in Saudi Arabia so we conducted this study to highlight these underreported neoplasms.OBJECTIVESDetermine the prevalence and patterns of basal cell carcinoma (BCC) and primary squamous cell carcinoma (SCC), the most common types of nonmelanoma skin cancer (NMSC) with respect to age, sex, and anatomic location and to identify potentially associated risk factors.DESIGNRetrospective, descriptive medical record review.SETTINGA tertiary care centre.PATIENTS AND METHODSWe did a retrospective chart review of all patients diagnosed with basal cell carcinoma and primary squamous cell carcinoma between 2003–2016.MAIN OUTCOME MEASURESPrevalence and pattern of BCC and SCC with respect to age, sex, and anatomic location.RESULTSOf 593 cases reviewed, 279 had NMSC. Most (95%) were diagnosed with BCC or SCC or both in a few cases. The mean age at diagnosis was 59 (19.5) years. Sixty-two percent of the patients were males. However, 24.3% (n=68) of skin cancers occurred in patients younger than 50 years. The frequency of BCC and SCC was 50.2% and 44.8%, respectively. The head and neck was the most common location (79.6%). In patients younger than 50 years, xeroderma pigmentosum and previously treated solid malignancies were the major factors.CONCLUSIONSBCC and SCC are uncommon but not rare. However, skin cancers are underreported in our population. NMSC in individuals younger than 50 years of age requires more careful evaluation of possible risk factors.LIMITATIONSRetrospective in a single tertiary care setting.

Background: The relationship between coffee and tea consumption and dental caries in Saudi Arabia has not been covered adequately. The aim of this cross-sectional study was to assess the association between the frequency and quantity of coffee and tea consumption and dental caries severity among adolescents (middle and high schools) in the Eastern Province, Saudi Arabia. Methods: A cross-sectional observational survey study that was carried out in Eastern Province, Saudi Arabia. Validated interview-based questionnaires were used to ask about the background information and the frequency and quantity of coffee and tea consumption with two sections of the survey: the first section was about the demographic data and the second section assessed the frequency and quantity of coffee and tea consumption and examination was done during daylight using disposable dental mirror and blunt probe. Result: A total of 2265 middle school children with a response rate of 77.8%. Out of them, Females accounted for 1288 (56%) and the mean age (±SD) was 14 (±1.322). Regarding parents’ education, 1916 (84.6%) of participants’ fathers and 1836 (81.1%) of their mothers had a high school certificate or higher. There was a significant association between the frequency of coffee and tea consumption and caries (p=0.013). Conclusion: There was a significant association between the frequency of coffee and tea consumption and caries (p=0.013). The frequency of coffee and tea consumption, the higher the caries. However, there was no association between the quantity of coffee and tea consumption and D nor with the overall DMF score.
