Merkel cell carcinoma associated with TNF inhibitor therapy: a systematic review of case reports.

A rare neuroendocrine skin cancer called Merkel cell carcinoma (MCC) primarily affects elderly people. The objective of this study is to comprehensively review the impact of immunosuppressive medications, particularly TNF inhibitors, on the emergence of MCC. METHODS: PubMed, Web of Science, Science Direct, and Cochrane Library were searched. Study articles were screened by title and abstract at Rayyan Qatar Computing Research Institute, then a full-text assessment was implemented. RESULTS: A total of eight case reports with 9 patients were included. Of the total population, seven were women and only two were men. Their age ranged from 31 to 73 years. More than half the population (5 cases) were being treated for rheumatoid arthritis. All received TNF inhibitors that were associated with the induction of MCC. CONCLUSION: We found that it is essential for physicians to explain potential cancer risks to patients before starting long-term immunosuppressive therapy and to conduct routine checks for MCC and other side effects. TNF inhibitors (infliximab, adalimumab, etanercept, and golimumab) were all associated with MCC development. Women constituted the majority of cases and most were elderly.

The Prevalence and Clinical Features of Skin Irritation Caused by Infection Prevention Measures During COVID-19 in Riyadh Region, Saudi Arabia.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), caused by a novel coronavirus (CoV), was reported at the end of 2019 and caused a severe public health concern. It caused high mortalities by respiratory failure among infected people and was declared a pandemic by the World Health Organization (WHO) in March 2020. This virus caused infections through air or direct contact which documented a huge number of fatalities. AIM: This study aims to examine the impact of the COVID-19 pandemic on skin eczema of the general public in the Riyadh region of Saudi Arabia. METHODS: This is a descriptive, cross-sectional, survey-based study, that was conducted via an online survey distributed to the general population of Riyadh for the period between January and February 2023. Data was collected through a questionnaire which was distributed through the social media websites. RESULTS: A total of 697 participants were involved in this study. Around one-fifth of the study participants (19.5%) reported that they suffer from some form of allergy and have family history of allergy (21.8%). Eczema was the most common type of allergy among the study participants accounting for 32.4%. A total of 116 participants (16.6%) reported that they have personal history of hand eczema or other skin disease on the hands. Cleaning and sterilization materials were reported as the most common cause of dryness and irritation of eczema (62.1%). Around 41.0% of the participants reported that they noticed a worsening of their symptoms after the pandemic, of which dryness was the most commonly reported sign noticed getting worse by 68.1% of the participants. The vast majority of the participants (89.7%) reported that new skin symptoms emerged on their hands after the beginning of the pandemic, of which dryness was reported by all the participants. CONCLUSION: A considerable proportion of participants, particularly those with a history of hand eczema, experienced dermatological difficulties, including skin damage, due to the usage of COVID-19 preventive strategies. Thus, we recommend increasing the use of innovative infection prevention approaches and skin protection measures, such as regular hand hydration and maybe the use of less toxic skin disinfectants.

Viral-Induced Rapidly Progressive Alopecia Universalis: A Case Report and Literature Review.

Alopecia areata is a common autoimmune condition that causes a non-scarring form of hair loss. It is associated with several viruses and diseases. One of the viruses that have been linked to alopecia areata is the coronavirus disease of 2019 (COVID-19). It was found to cause the onset, aggravation, or recurrence of alopecia areata in previously infected patients. We report the case of a 20-year-old woman who was medically free and presented with the severe and progressive onset of alopecia areata after one month of contracting COVID-19. This study aimed to explore the literature on COVID-19-associated severe onset alopecia areata in terms of timeline and clinical presentation.

The psychosocial burden of androgenetic alopecia in Saudi Arabia: A cross-sectional study.

Background: The most prevalent cause of hair loss is androgenetic alopecia. Improved therapeutic modalities may result from knowing how stress affects hair growth, incorporating stress-coping methods into the treatment of hair loss disorders, and developing new pharmacotherapeutic approaches. This study aimed to examine the psychosocial burden of androgenetic alopecia in Saudi Arabia. Materials and Methods: A cross-sectional online survey study was conducted among patients with androgenetic alopecia in Saudi Arabia in February 2023. A previously developed questionnaire was adapted from a previously published tool and used in this study. This association between patients' characteristics and the level of psychosocial disease was identified using binary logistic regression analysis. Results: This study included 1230 patients. The majority of the patients (78.0%) reported that they felt embarrassed by their androgenetic alopecia. The median score of the psychosocial impact of androgenetic alopecia on the patients was 1.00 (0.00-2.00), which is equal to 10.0%, reflecting a low level of psychosocial burden on the patients by their condition. Binary logistic regression analysis identified that patients without a family history of androgenetic alopecia were 36.0% less likely to be affected psychosocially by their condition (P < 0.01). Conclusions: A low-level psychosocial effect was seen in our study among individuals with androgenetic alopecia. Further research should be done to determine how the type of alopecia affects patients' psychological results, as well as the influence of the disease's duration on those outcomes. Dermatologists are recommended to raise patients' knowledge of their disease and lessen stigmatization in the meantime.

Clinicians' and Students' Perceptions and Attitudes Regarding the Anatomical Knowledge of Medical Students.

Background: In both the preclinical and clinical sciences, anatomy is considered as the foundation of medical education. Anatomy education serves as a foundation for clinical application and future practice of medicine. Health practitioners and students are interested in the adequacy of anatomical knowledge in clinical years since it has a direct impact on medical education and professional clinical practice. Objective: To examine the opinions and attitudes of medical students and clinicians regarding the preclinical and clinical years' teaching of anatomy and anatomical knowledge to medical students. Methods: Participants in the study, including clinicians and medical students, were required to answer an 8-question, 5-point Likert scale questionnaire to assess their attitudes regarding anatomical knowledge. The maximum score was 40, and the higher the score, the more the positive attitude towards anatomical knowledge. The difference in the mean attitude score between males and females was investigated using the Independent sample t-test. Results: A total of 327 clinicians and 423 students participated in the study. Clinicians and students showed moderately high positive attitude towards anatomical knowledge. The mean statements score for clinicians' attitudes was 31.4(±3.4). There was no significant difference between total attitude score means for clinicians and students, p=0.83. Attitude statements attained a significantly higher percentages and were in favor to clinicians in comparison to students, particularly for clinical significance of anatomical knowledge to students in the clinical years, the importance of anatomical knowledge to surgical and non-surgical specialties, and re-teaching special anatomy for students in the clinical years would improve their clinical background. Both clinicians and students expressed low agreement regarding anatomical educational style and quality of study materials. Conclusion: Teaching anatomy to medical students is a continuous process. Therefore, we recommend reforming the anatomy curriculum by vertical integration of anatomy into the clinical rotations, clerkship, and specialist training.
