Correlation between depression scores and serum NF-ĸB/NLRP3 axis, biotinidase, and HMGB1 after treatment with isotretinoin in patients with acne vulgaris.

BACKGROUND: Acne vulgaris (AV) is an inflammatory skin disorder leading to scars and discomfort, its intensity has major psychological consequences such as depression. AIM: To investigate the effect of isotretinoin (ISO) on NF-κB/NLRP3, biotinidase, and HMGB and correlation with depression. PATIENTS AND METHODS: This was a case-control study that involved two groups. Group 1 is 20 healthy control, and group 2 is 20 patients diagnosed with AV according to Global Acne Grading System (GAGS) and received 20 mg ISO for 2 months. Before and after therapy, the Hamilton Depression Rating Scale (HDRS) was applied to assess each participant's level of depression. Nuclear factor kappa B (NF-ĸB), biotinidase, high mobility group box protein (HMGB1), nucleotide-binding domain, leucine-rich-containing family, and pyrin domain-containing-3 (NLRP-3) were measured in serum samples. RESULTS: There was no significant difference in all measured markers of healthy group before and after 2 months. Regarding group 2, there was a statistically significant decrease in all measured markers after 2 months of treatment and significant correlations between GAGS, NF-ĸB, HMGB1, NLRP3, biotinidase, and depression score. CONCLUSION: Increased GAGS, HMGB1, NLRP3, and biotinidase were associated with depression severity in AV patients and ISO treatment significantly reduced these parameters and reduced depressive symptoms.

Ethnicity is a major determinant of the pattern of dermatological diseases among pilgrims during the Hajj in 2019.

The authors aim to explore the pattern and demographics of dermatological disorders occurring during Hajj 2019. Clinical records from three major public healthcare facilities in Al-Madinah Al-Munawara were retrieved for the period July-August, 2019. Collected data included age, gender, nationality, and dermatological complaints. 550 records were retrieved. Patients were 282 (51.3%) males and 268 (48.7%) females with a mean age of 58.3±12.6 years. Most patients were Asians (n=320, 58.2%), and Africans (n=183, 33.3%). Accidents (n=226, 41.1%), and infections (148, 26.9%) were the most common complaints. Asians and Africans had significantly: more accidents and less infections (P=0.002, P=0.027 respectively). They were the only category affected by exacerbations of auto immune diseases. Asian and African pilgrims are mainly affected by traumatic dermatologic conditions. Preventive awareness programs should target these ethnicities to reduce their higher rates of accidents. Other ethnicities need programs that promote hygienic practices and target infections.

Comparison between the efficacy and safety of platelet-rich plasma vs. microdermabrasion in the treatment of striae distensae: clinical and histopathological study.

Striae distensae is a challenging cosmetic problem for which various treatment modalities have been applied. To compare between the efficacy and tolerability of intradermal injection of autologous platelet-rich plasma (PRP) vs. microdermabrasion in the treatment of striae distensae. Sixty-eight patients with striae distensae were randomly assigned to three groups according to therapeutic modalities. Patients of group I were treated by intradermal injection of PRP alone, patients of group II were treated with microdermabrasion alone, and patients of group III were treated with combination of intradermal PRP and microdermabrasion in the same session. Each patient underwent maximum of six sessions at 2-week interval. Skin biopsies were taken from some patients at baseline, and 3 months after the last sessions stained with hematoxylin and eosin stain, Masson trichrome, orceun, and Van Gieson stains to study of histopathological changes and efficacy of treatment. There was significant clinical improvement of striae distensae in patients treated with PRP injection and patients treated with combination of PRP and microdermabrasion when compared with patients treated with microdermabrasion. However, combination of PRP and microdermabrasion in the same session showed better results in short duration. Collagen and elastic fibers were markedly increased in the dermis at the end of treatment sessions. Platelet-rich plasma alone is more effective than microdermabrasion alone in the treatment of striae distensae, but it is better to use the combination of both for more and rapid efficacy. However, each one of them is well tolerated by the patients, safe and cost effective.
