Impact of Pandemic in the Frequency of Scabies: Possible Scabies Outbreak Scenario Aftermath COVID-19

Objective: This study aimed to evaluate the post-pandemic changes in the frequency of scabies and determined the clues that may indicate a possible outbreak of scabies in the future. Methods: All patients diagnosed with scabies in the University of Health Sciences Turkey, Erzurum Regional Training and Research Hospital and Palandöken State Hospital between January 2019 and September 2020 were evaluated. Results: The frequency of scabies of 1.87% was remarkable in the first quarter of 2020, which corresponds to the pre-pandemic, and >50% (n=442) of all patients with scabies in 2019 (n=769) were encountered only in the first 3 months. The frequency of scabies seen in the first 3 quarters of 2020 was significantly higher than in 2019 (p<0.001). Significant decreases were found in the 0-14 years age groups (infant, preschool and school period) compared to 2019 (p<0.001, p<0.001 and p=0.015, respectively). No significant increase or decrease was determined in the frequency of scabies in 2020 (p=0.205). In addition, an increase in the number and rates of scabies patients are observed after the first month of normalisation period followed by the increase in the number of Coronavirus disease-2019 (COVID-19) daily cases. Conclusion: Applications for scabies to polyclinics after the pandemic were determined to be too low compared to previous periods, especially in school-age children, and showed an increasing trend over time. Patients with scabies that reach treatment late or not due to the pandemic may cause outbreak aftermath COVID-19.

Evaluation of the frequency and intensity of favipiravir-associated yellow-green fluorescence in lunulae, hair, and face.

BACKGROUND: We detected yellow-green fluorescence in the face, hair and lunulae of patients using favipiravir. AIM: We evaluated the frequency and intensity of favipiravir-associated fluorescence. PATIENTS/METHODS: The participants comprised patients who had taken at least a single dose of favipiravir and been examined no later than 30 days after the last dose. The gender, age, body mass index (BMI), Fitzpatrick's skin-type, hair color, N-acetylcysteine use, presence and the intensity of fluorescent reflection under Wood's light in the lunulae of the fingernails, hair, and the face were recorded. RESULTS: There were 275 patients, 144 (52.4%) of whom were women. 165 (57.9%) had used treatment for a maximum of 5 days, 99 (34.7%) for 6-10 days, and 21 (7.4%) for more than ten days. Using more than 22 tablets of favipiravir increased the probability of detecting fluorescence in the lunulae by 6.72 (2.61-17.23) times. Using more than 28 tablets increased the risk of fluorescence in hair and the T-zone by 5.92 (2.43-14.71) and 2.88 (1.11-7.47) times, respectively. No relationship was found between the fluorescence intensity in any localization and the total dose. However, we determined a negative correlation between the elapsed time after the last dose and the fluorescence intensity in the lunulae and the T-zone (p=0.036; p=0.031; respectively). It was noted that BMI negatively correlated with the fluorescence intensity in the lunulae (p=0.001). Skin type was related to intensity for all localizations (p<0.001). Fluorescence was found in the lunulae with significantly less frequency in patients using N-acetylcysteine (p=0.040). CONCLUSIONS: We must be aware of favipiravir-induced phototoxicity.

Change of the diagnostic distribution in applicants to dermatology after COVID-19 pandemic: What it whispers to us?

We aim to evaluate the change in the diagnostic spectrum in dermatology outpatient applications compared to before COVID-19. All patients were enrolled from the Department of Dermatology between February 12 and May 8, 2020, the duration of 4 weeks before COVID-19 and 8 weeks after were analyzed in three parts consisting of 4 weeks. Data obtained from the database such as age, gender, diagnoses were anonymized. Repeated applications with the same diagnosis in 10 days after the first presentation were ignored. Compared to the pre-outbreak, there was a 3.5-fold decrease in dermatology applications in the first month after COVID-19 and an 8.8-fold in the second month. We found a significant increase in the frequency of diagnoses such as generalized pruritus, pityriasis rosea, alopecia areata, bacterial skin/mucosa diseases, and zona zoster after COVID-19. The frequency declined in diseases such as verruca vulgaris, hyperpigmentation, skin tag, melanocytic nevus, and seborrheic keratosis/solar lentigo. It has been found that the frequencies of most diseases, including acne (⁓25% of patients), did not change. We think that many factors, such as affecting the quality of life, risk perception, increased stress burden may cause a change in the diagnostic distribution of the dermatology applications.
