Various cutaneous manifestations have been observed in patients with COVID‐19 infection. Herpes zoster is a viral skin disease caused by varicella zoster that remains dormant in the dorsal root ganglia of cutaneous nerves following a primary chicken pox infection. In this report, we describe two cases COVID infection who first presented with herpes zoster. We are here by suggesting that the clinical presentation of HZ at the time of the current pandemic even in patients giving mild or no suggestive history of upper respiratory symptoms should be considered as an alarming sign for a recent subclinical SARS CoV2 infection.

Follicle-stimulating hormone (FSH) is fundamental for Sertoli cell function stimulating spermatogenesis and follicular growth by a specific receptor (FSHR). This work aimed to investigate the occurrence of Asn and Ser FSHR gene variants and its relationship with seminal anti-Müllerian hormone (AMH) among normozoospermic and infertile oligoasthenozoospermic (OAT) males. Eighty-two Caucasian males grouped into normozoospermic healthy controls (n = 30) and infertile OAT males (n = 52). FSHR gene variants were determined by DNA from anti-coagulated blood and underwent polymerase chain reaction (PCR) amplification and electrophoresis in detecting amplification products. AMH in seminal plasma was determined by ELISA. The results showed that the frequency of FSHR gene variants among fertile men was 46.7% Asn/Asn (N680S), 33.3% Asn/Ser, and 20% Ser/Ser, whereas among OAT men were 34.6%, 38.5% and 26.9% respectively with nonsignificant differences. Seminal AMH was significantly higher in fertile than infertile OAT men. There was significant increase in seminal AMH with Asn/Asn variant of FSHR gene than those with Asn/Ser or Ser/Ser. It is concluded that FSH gene variants showed no difference in distribution between fertile or infertile OAT men. However, when correlated with seminal AMH values, there was an increase in Asn/Asn in men with high seminal AMH.

After 20 sessions, it appears that lower doses of UVA (5, 10 J/cm(2)) are as beneficial as the relatively higher dose (20 J/cm(2)) in the treatment of M and SS.

Background Efficacy and safety of ablative fractional laser used for treatment of acne scars have been described in several studies. Recently, microneedling radiofrequency treatment has been showing promising results with low risk of side effects and rapid healing time. Objective To study efficacy and safety of ablative fractional Er:YAG laser 2940 nm and microneedling radiofrequency for facial atrophic acne scar. Methods 21 patients with atrophic postacne scars were randomized to MRF for one half of the face and laser for the other half. Four sessions were performed monthly. For evaluation, the validated scale “Quantitative Global Grading System for Postacne Scarring” and patient's satisfaction were used before and 3 months after treatment. Optical coherence tomography imaging of the skin was used as an objective tool for assessment. Results Both sides showed significant improvement on clinical evaluation with no significant difference. Optical coherence tomography assessment showed significant increase of both epidermal and dermal thickness compared to baseline. Conclusion Both MRF and ablative fractional Er. YAG laser 2940 nm are effective in the treatment of post acne scars. Microneedling radiofrequency is better tolerated, with lower downtime and fewer side effects.

S. aureus may play an important role as an aggravating factor in AD patients. Reducing the colonization of atopic skin by S. aureus is therefore the best way to reduce superantigen-induced allergic skin inflammation.
