RESUMO
Contact dermatitis is a chronic inflammatory skin disorder with a highly variable prevalence worldwide. Smoking plays a crucial role in mediating inflammatory skin conditions such as contact dermatitis. The present study aimed to investigate the association between smoking status and contact dermatitis in the Saudi population. The patients in the present study were individuals older than 18 years who were diagnosed with contact dermatitis and received a patch test at the Department of Dermatology of King Saud University Medical City from March 2003 through February 2019. All patients were interviewed by phone to complete a specific pre-designed questionnaire to assess tobacco use or exposure history. The total number of enrolled patients in the study was 308 (91 males and 217 females), all with contact dermatitis. Data from the present study suggest that the prevalence of allergic contact dermatitis in smokers may be less than that in non-smokers. Moreover, the prevalence of irritant contact dermatitis in smokers is more significant than in non-smokers. Finally, left-hand contact dermatitis is significantly associated with smoking. Therefore, there is a strong association between smoking and irritant contact dermatitis, especially in the Saudi population, regarding the left hand. Further epidemiologic studies are needed to further explore the role of smoking in the occurrence of contact dermatitis and to explore the possible mechanisms.
RESUMO
Background: Infantile hemangioma is the most frequent benign vascular tumor of infancy, which has a specific clinical history of early growth, followed by spontaneous remission. Since the fortuitous discovery of propranolol's efficacy in 2008, the management of infantile hemangioma has been quickly developing. Methods: This study is a retrospective cohort study. Electronic search in the patient's registry of King Khalid University Hospital, Riyadh, Saudi Arabia, was performed using the keywords hemangioma, haemangioma, infantile hemangioma, and vascular tumors. The search revealed a total of 101 subjects for which 56 were included and 45 were excluded. Results: A total of 56 patients with infantile hemangioma were evaluated in this study. The majority were females. The F: M ratio is 3.4:1. The highest percentage of the patients was delivered by the elective cesarian section, that is, 23 (41.1%), followed by spontaneous vaginal delivery, that is, 19 (33.9%). Full-term patients were 27 (48%), whereas the pre-term patients were 21 (37%). The total number of patients who developed hyperkalemia while on propranolol was 12 (31%). There was no statistically significant difference (P > 0.05) between patients who developed hyperkalemia and patients who did not develop hyperkalemia in terms of gender, gestational age, mode of delivery, size and location of hemangioma, or concomitant topical timolol use. Conclusion: Hyperkalemia is benign and transient, although solid conclusive opinions cannot be drawn because of the small sample size and the retrospective nature of the study.
RESUMO
BACKGROUND: The multifactorial nature of rosacea and chronic spontaneous urticaria (CSU) pathogenesis complicates the achievement of satisfactory treatment outcomes. 13C urea breath test (UBT) has been identified as an accurate, non-invasive, and quick procedure to detect the presence of Helicobacter pylori (H. pylori) with high sensitivity and specificity. OBJECTIVE: In this study, we aim to assess the correlation between H. pylori infection and rosacea and CSU patients. METHODS: A cross-sectional, observational study was conducted on patients with rosacea and CSU in the dermatology clinic at King Khalid University Hospital in Riyadh, Saudi Arabia. History and physical examination were performed by a dermatologist. H. pylori 13C-UBT detection was performed in all subjects. RESULTS: In total, 114 patients were included in this current study, with 41 rosacea and 73 urticaria patients. The vast majority of our subjects were females (96.5%). The mean (±SD) age was 42.3 (±12.7). More than half (58.8%) of the examined samples were positive for 13C-UBT; however, positive results were significantly higher in the rosacea patients (73.2%) compared to the urticaria group (50.7%), with a p-value of 0.019. CONCLUSION: Our findings underline the significant association of H. pylori with rosacea and CSU regardless of the presence or absence of gastrointestinal symptoms. We thus recommend the inclusion of H. pylori testing in the routine workup of CSU and rosacea patients.
RESUMO
Ocular involvement in pemphigus vulgaris (PV) is relatively rare. The conjunctiva and eyelids are considered the most common affected sites in ocular pemphigus. Scleritis is rarely reported as a manifestation of PV. We present a case report of anterior scleritis as a manifestation of PV and its response to rituximab therapy.
