Introduction: Lung cancer is one of the leading causes of cancer-related deaths worldwide, including in Saudi Arabia. In the past few decades, the incidence and mortality has increased considerably among the Saudi population. The incidence of lung cancer has increased more than 3% in less than two decades. The current study focuses on analyzing the frequency of diagnosed lung cancer cases, age-standardized incidence rate (ASIR), and crude incidence rate (CIR) classified by year of diagnosis, age group, and different administrative regions of Saudi Arabia, based on the Saudi cancer registry (SCR) for the period of 10 years from 2006–2016. Methodology: The present study is a cohort study that focuses on the epidemiological analysis of lung cancer cases. The statistical analysis was performed by t-test, sex ratio, Kruskal–Wallis, and descriptive statistics through SPSS version 20.0. Results: A total of 4530 lung cancer cases were reported from January 2006 to December 2016. Among males, the ASIR range was reported as 1.2 to 12.3 per 100,000 cases in different regions of Saudi Arabia. Moreover, among females, the ASIR range was reported from 0.2 to 3.1 per 100,000 cases in different regions of Saudi Arabia. Additionally, the overall age-standardized incidence sex ratio was 3.2 per 100,000 cases. The incidence of lung cancer increased with age as 23% was reported in the age group of more than 75 years. Conclusion: The study concludes a rise in crude incidence rates and ASIR for lung cancer among Saudi population. Among males, the Eastern region had the highest overall ASIR followed by Tabuk region, and, among females, the highest overall ASIR was reported in the Eastern region followed by Riyadh and the Northern region.

Aim: The primary aim of this study was to detect the prevalence of dental implants in a Saudi population in the Kingdom of Saudi Arabia. The secondary objective was to describe the status of the health insurance covering dental implants in Saudi Arabia. Materials and Methods: 1831 Saudi patients aged ≥18 years with at least one missing permanent tooth and residing in the Kingdom of Saudi Arabia were randomly selected and clinically examined for implant prostheses types (single-tooth implant, implant-supported long or short span conventional fixed bridge, implant over denture). Radiographs were used too. The health insurance covering dental implants was detected. The data obtained including age, gender, systemic disease, and tobacco smoking were documented in a patient examination form then statistically analyzed using Chi-Square Test or Fisher-Freeman-Halton Test and U-Test. Results: The prevalence of dental implants among adults missing at least one tooth was 12.7%. Of those 12.7%, the majority of patients had 2-4 implants (5.4%). The majority of patients who had one implant were in the age group <40 years; patients who had >8 implants were seen in the age group ≥60. In addition, the prevalence of implant prostheses types was as the following: Single-tooth implant 75.5%, followed by implant-supported short span fixed bridge 17.1%, implant over denture 3.9%, and implant-supported long span fixed bridge 3.5%. The majority of patients treated with single-tooth implant were in the age group <40 years. There was an insignificant difference in the median number of dental implants between males and females p>0.05. Conclusion: The majority of patients were treated with single-tooth implant. Health insurance policy doesn’t cover the cost of dental implants in Saudi Arabia. Keywords: Implant, Prevalence, Prostheses/Prosthesis, Type, Patient

AimsThe aim of this study was to elucidate the epidemiological background of central serous chorioretinopathy (CSC), including its incidence and treatment pattern.MethodsThis was a population-based longitudinal cohort study using a nationwide health insurance claims database of the Japan Ministry of Health, Labour and Welfare (MHLW). As Japan employs universal health coverage, the database covers more than 95% of claims issued in Japan. We accessed all data stored in the database with permission from the MHLW. We traced all individuals aged 30 years or older and identified individuals with new onset of CSC between January 2011 and December 2018. CSC cases were categorised by age and sex for each year, and incidence rate was calculated. We also identified major treatments for CSC to elucidate the initial treatment pattern.ResultsDuring the 8-year period, 247 930 incidences of CSC were identified, among which 75.9% were men. The crude incidence rate (per 100 000 person-years) in the general population aged 30 years or older was 34.0 (95% CI 33.9 to 34.2), in men was 54.2 (95% CI 53.9 to 54.4) and in women was 15.7 (95% CI 15.5 to 15.8). The mean age of onset was lower in men than in women (50.5±12.5 years vs 54.7±13.5 years). Most of the patients with newly diagnosed CSC (86.8%) did not receive major treatment.ConclusionsThe current study provides the nationwide population-based evidence to clarify the detailed epidemiology of CSC. These results could help to understand the pathogenesis and mechanisms of CSC in the future.
