BoNTA therapy resulted in improvements in subjective patient symptomatology and objective reductions in erythema and maceration in the treated areas according to photographic evidence. Further large-scale methodologically rigorous studies are required to investigate the safety and efficacy of BoNTA in this indication.

Excessive, incorrect exposure to the sun at a young age can be a risk factor for skin cancer at a later age. In this study we have investigated the exposure and protection habits of a group of children to see whether there are behavioral errors that should and possibly could be corrected. We handed out a multiple-choice questionnaire to 310 subjects, 212 boys and 98 girls between the ages of 6 and 14, all residents in the province of Udine in the northeastern part of Italy. Of these children, 24% had sunburn on several occasions; boys were four times more at risk than girls (OR = 0.4) and the frequency reduced by 30% for each skin phototype class higher. In children between 11 and 14 years of age, exposure was prolonged (43% for 2-4 hours, 38% for 4-8 hours) and 30% preferred peak hours. Eighty percent of the children, mostly girls, younger children (6-10), and the lower skin phototypes used sunscreens, but only 38% used them on a regular basis, whereas 20% applied them after sunbathing and 42% used a single daily application. Two percent of the children used sunglasses and 5% wore a T-shirt regularly. The dermatologist and pediatrician play an important role in advising parents that the sun is good for children, but appropriate measures must be taken to reduce any risks, both immediately and in the long term.

The present study aimed at assessing the consequences of prolonged exposure to COVID-19 distress on mental health in non-frontline health care workers. For this purpose, we have conducted a survey on 425 Italian dermatologists, in the period February–March 2021. The psychopathological symptoms, depression, anxiety, post-traumatic stress symptoms (PTSD), as well as resilience, have been evaluated. The main factors that influence the physician’s psychological health have been also investigated. Our study showed that the physicians older than 40 years, as well as those who lived this period in company, reported more personal resources, better managing the distress. Resilience, COVID-19 beliefs, COVID-19 working difficulties, and age were the common predictors of the severe psychopathological symptoms. An interesting result is that the lower level of resilience was the most powerful predictor of a more severe depression, as well as of a higher severity of generalized anxiety disorder, but not of COVID-19 PTSD. The fear of COVID-19 was the most powerful predictor of COVID-19 PTSD. Home conditions and previous SARS-CoV2 infection constituted significant predictors of severe depressive symptoms, but not of anxiety and COVID-19 PTSD. These results are useful in a better understanding of protective and risk factors involved in COVID-19 long-term distress exposure.

Primary palmar hyperhidrosis is a distressing and disabling condition that can produce social, psychological and occupational problems. Although the use of botulinum toxin type A (BoNT-A) has been reported as an efficacious and safe intervention to improve palmar hyperhidrosis, only one study concerned botulinum toxin type B (BoNT-B) in this disorder. The aim of study was to evaluate the efficacy and safety of BoNT-B in treating primary palmar hyperhidrosis. Participants were injected with 5,000 IU of BoNT-B in each palm. Visual analogue test (VAS) to evaluate the intensity of decrease in sweat production, Minor's iodine starch test and measurement of paper towels' weight were used to ascertain palmar sweating at baseline, 4, 12 and 24 weeks after BoNT-B injections by a blind examiner. Thirty-two subjects (12 males, 20 females, mean age 31 ± 11) were enrolled. Significant reduction of palmar sweating was detected after BoNT-B injection: 2.9 ± 1.4, 0.3 ± 0.4, 0.9 ± 0.8, and 2.1 ± 1.5 g (p < 0.001) of paper towels' weight for the right palm at baseline, 4, 12 and 24 weeks; and 2.8 ± 1.7, 0.5 ± 0.6, 0.8 ± 0.7, and 1.8 ± 1.25 g (p < 0.001) at same time, respectively for the left palm. Significant reduction of mean VAS values were also detected after BoNT-B injections: 8.6 ± 1.1, 0.6 ± 0.8, 3.5 ± 2.5, and 7.1 ± 2.4 (p < 0.0001) at baseline, 4, 12 and 24 weeks, respectively. Mild side effects consisting in local pain and hand weakness were observed in 4 (12.5%) subjects. The findings indicated that the use of 5,000 IU BoNT-B injection in each palm was safe and significantly improved the severity of palmar hyperhidrosis.
