Background: Shade selection is an essential system to give patients an aesthetics renovation that correspondently merges to the patient's current dentition. Moreover, natural teeth are acknowledged to have various shades in their surfaces. Objective: The aim of the study was to evaluate the awareness of knowledge, attitude and practice about the complications in shade selection and to utilize for improving the quality of training being imparted in the dental school and general practitioners. Methods and Material: Participants were divided into six Groups: operative dentist and endodontist, 3rd Year students, 4th Year students, 5th Year students, Intern and VI-General practitioners; 20 Questionnaire survey forms were distributed to fill among all the groups. Results: The results that the highest proportion was 41% for skill factor, knowledge was the second with 26%. Whilst, individual observer was 13.5% and 12.6% for the factor talent. 4.5% for (All) the factors. The lowest proportion was for more than two answers. Conclusion and Recommendation:The need of flourishing of cosmetic dentistry required to keep with up-todate information considering all conceivable factors which influence shade selection.

Background Somatoform disorder (SD), known as the presence of physical symptoms suggesting a physical condition, for which there are no demonstrable organic findings or established physiological mechanisms with positive evidence that the symptoms are related to psychological causes. The aim of this study was to highlight the epidemiological characteristics, demographic features, comorbidities, and clinical presentations of patients with SD. Materials and methods This was a retrospective study of SD patients at King Abdulaziz Medical City in Riyadh, Saudi Arabia. We reviewed the patients' electronic health records from January 2015 to December 2020 for collecting the patients’ demographic information, including gender, age, marital status, and occupation. The types of SD, presenting symptoms of each disorder, department to which patients initially presented, comorbidities, and management were also documented. The diagnosis of SD was based on the International Classification of Diseases, Tenth Revision (ICD-10). Results In total, 89 patients were included in the study. The majority (n=50, 56.2%) were female, with a mean age of 42.7±17.1 years. More than half of the sample was married (n=54, 60.7%). The most common subtype of SD was somatization disorder followed by conversion disorder, pain disorder, and hypochondriasis, diagnosed in 69 (77.5%), 12 (13.5%), 5 (5.6%), and three (3.4%) patients, respectively. Neurological symptoms and pain were the most frequent presenting symptoms for all the somatoform patients. More than half of the sample (n=48, 53.9%) initially presented at an outpatient clinic. Conclusions The number of SD patients was less than expected, and a third did not receive any treatment. This emphasizes the need for more SD awareness among clinicians in various medical specialties. Appropriate SD and other mental disorders education for physicians may support achieving a better identification of SD and subsequently an improved quality of life for the patients.

BackgroundObesity has become a major health concern associated with several comorbidities. Obesity has been connected to numerous variables. Furthermore, multiple studies were done worldwide to identify the relationship between obesity and Helicobacter pylori (H. pylori), and there was controversy. However, the relationship between H. pylori infection and obesity in our community is still not clear, and there is a knowledge gap. AimTo determine the relationship between asymptomatic H. pylori infection and body mass index (BMI) among patients who underwent bariatric surgery in Saudi Arabia, King Fahad Specialist Hospital -Buraidah (KFSH-B). MethodAn observational retrospective cohort study was conducted at KFSH-B. Patients with high BMI (>30 kg/m2) who underwent bariatric surgery between January 2017 and December 2019 were included. Gender, age, BMI, and upper GI endoscopy reports of preoperative mapping were collected from electronic health records. ResultsThe sample size was 718, and the mean BMI (standard deviation) was 45 kg (6.8). Patients with positive H. pylori results were 245 (34.1%) and patients with negative H. pylori results were 473 (65.9%). The t-test showed the mean BMI of patients with negative H. pylori results to be 45.36 (SD 6.6). Positive H. pylori 44.95 (SD 7.2) p-value was not significant (0.44). ConclusionThe data showed that patients who had undergone bariatric surgery had negative pre-operative histopathological results of H. pylori more than those who had positive results, which is consistent with the prevalence of H. pylori infection among the general population. Therefore, we found no correlation between H. pylori infection and high BMI.

Coronaviruses (CoV) are RNA respiratory viruses that present with a wide range of symptomatology which range from common cold to severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). In December 2019 a new strain was discovered in China named Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2), named “COVID-19” by World Health Organization (WHO). Objective: To study the prevalence and clinical presentation of COVID-19 among children attended pediatrics emergency department. Result: from 1st March to 30th of June 2020. During the study period, a total of 223 patients with age between 16 days and 12 years were diagnosed as positive COVID-19. Male were 52%. Fever was found in 39.9%, cough in 14.3%, and diarrhea in 3.6%. Conclusion: our study gives a clue to the clinical presentation of COVID-19 in pediatric populations.
