: Cancer is currently one of the main health issues in the world. Among different varieties of cancers, skin cancer is the most common cancer in the world and accounts for 75% of the world's cancer. Indeed, skin cancer involves abnormal changes in the outer layer of the skin. Although most people with skin cancer are healed, it is one of the major concerns of people due to its high prevalence. Most types of skin cancers grow only locally and invade adjacent tissues, but some of them, especially melanoma (cancer of the pigment cells), which is the rarest type of skin cancer, may spread through the circulatory system or lymphatic system and reach the farthest points of the body. Many papers have been reviewed about the application of image processing in cancer detection. In this paper, a literature review on the automatic skin cancer detection and also different steps of such a are discussed process based on the implantation capabilities.

Article InfoBackground: COVID-19 is a viral infection that causes pneumonia with dyspnea, cough, and fever. Its outcomes are more severe in patients with diabetes, hypertension, and other disorders than in healthy people. New-onset diabetes and diabetic ketoacidosis (DKA) have been reported as the complications of COVID-19 in several studies. It seems that the prevalence of DKA due to Covid-19 is increasing. Therefore, two cases of individuals with DKA due to COVID-19 are presented in this study to inform other researchers about the details of this phenomenon. Material and Methods: Demographic characteristics, medical histories, physical examinations, laboratory investigations, real-time RT-PCR tests, computed tomography (CT) imaging studies, given treatments, clinical courses, and management outcomes were documented prospectively. Results: In the present experience, the manifestation of COVID-19 disease in the second case with a history of diabetes was more severe than in the first case. In the second case, with underlying diabetes and COVID-19, the DKA manifestation was associated with consciousness loss, severe restlessness, and respiratory distress; however, in the first case, with COVID-19 without diabetes, the DKA manifestation was associated with anorexia, weight loss, and lack of respiratory distress, which were milder symptoms than the second case. Conclusion: Due to the high prevalence of diabetes mellitus and COVID-19 in Iran, it is recommended to raise awareness of DKA symptoms among health professionals.

Background: Prediabetes is a high-risk state for developing diabetes at an annual rate of 5%–10%. Early intervention can prevent further complications, including metabolic syndrome. Bisphosphonates are commonly used for osteoporotic postmenopausal women. The purpose of this study was to assess the effects of bisphosphonates on lipid profile including triglyceride (TG), total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) of prediabetic postmenopausal women with osteopenia. Materials and Methods: In this triple-blind randomized controlled trial, sixty prediabetic, postmenopausal women with sufficient Vitamin D and osteopenia, aged 45–60 years, were randomly enrolled in two groups of intervention (receiving 70-mg alendronate for 12 weeks [duration for maximum metabolic effect of bisphosphonates], n = 30) and control (receiving placebo, n = 30) according to a randomized block procedure of size 2 and 1:1 allocation ratio. The primary outcome of the study, the lipid profile, was evaluated before and after the interventions. The effect of the intervention was assessed using analysis of covariance. Results: The lipid profiles showed no significant differences to the mean values at the baseline in both the groups (all P > 0.05). At the end of the study, the differences between the groups were not significant for 25(OH) D 3 (mean difference: −11.09, 95% confidence interval: −32.43–10.25), T (4.19, −30.58–38.97), cholesterol (8.13, −13.07–29.33), LDL-cholesterol (5.07, −10.18–20.31), and HDL-cholesterol (−0.86, −6.04–4.31) when the baseline values and confounders were adjusted (all P > 0.05). Conclusion: No statistically significant difference was detected in the serum lipid profile of prediabetic postmenopausal women with osteopenia as a result of alendronate intervention. More studies with larger sample sizes and longer intervention periods are recommended.

Background and Objectives: According the importance of iodine monitoring in the prevention of iodine deficiency disorders, this study aimed to evaluate the clinical iodine and goiter deficiency in 7-12 year-old students in Rafsanjan in 2018-19. Materials and Methods:The statistical population of this cross-sectional study included all students of 7-12 years old who were covered by Rafsanjan Education Management in 2018. From 21218 students aged 7 to 12 years living in the city, 1203 students (601 boys and 602 girls) based on inclusion criteria were enrolled in the study. After obtaining informed consent from the parents, the students were examined clinically by an internal trained resident. In this study, the presence and severity of goiter were evaluated based on the World Health Organiaztion classification.Then, 10 ml of the morning urine sample of 10% of all samples was taken to measure iodine by acid digestion method. Results:The mean and standard deviation of age of participants was 9.48±1.71. In addition, mean and standard deviation of urinary iodine was 183.33±80.52 Ug / dl. In the study of the prevalence of goiter in the community, 87.1% (1047 samples) had no goiter, 9.7% (117 samples) had D1 grade and 3.2% (39 samples) had D2 grade. It was also found that the prevalence of goiter was not statistically significant in terms of age and sex. Conclusion:The findings of this study indicate that the iodine deficiency control program and consumption of iodized salt has caused a significant decrease in the prevalence and severity of goiter, and also adequacy of the received iodine, given a marked increase in urinary iodine excretion in Rafsanjan city.
