RESUMO
Introduction: Dissecting cellulitis of the scalp (DCS) is a neutrophilic scarring alopecia typically presenting with pustules and fluctuant nodules, followed by suppuration and sinus tract formation. DCS is often associated with other diseases, such as hidradenitis suppurativa (HS) and conglobate acne (CA) which share similar pathogenetic mechanisms. Case Presentation: The authors report the case of a patient affected by a severe form of DCS, HS, and CA of the face. Previous treatments with isotretinoin, antibiotics, and adalimumab did not have a considerable efficacy. Off-label treatment with secukinumab showed a gradual improvement in the clinical presentation bringing to a reduction in the number of HS lesions and to an almost complete resolution of the inflammatory manifestations of DCS. Conclusion: Management of DCS is challenging and is typically based on retinoids which are considered the first line of treatment. The efficacy of biologic drugs, especially TNFα inhibitors, in severe and relapsing forms of DCS has been reported in recent literature. To our knowledge, only one case of isolated DCS treated with secukinumab is reported. No cases of concomitant DCS and HS, treated with this type of IL-17 inhibitor, have been described.
RESUMO
Acne is a multifactorial and common disorder among young people and a frequent reason for dermatology consultation. When moderate-to-severe acne is not responsive to conventional treatments, oral isotretinoin is a very effective solution. However, there are cases in which this treatment fails to produce the expected results. In this case, an 18-year-old male patient with acne, unresponsive to traditional acne therapies, experienced only a partial benefit from oral isotretinoin. Endocrinology consultation and hormonal work-up revealed androgen metabolism anomalies suggestive of a non-classical form of congenital adrenal hyperplasia due to 21-hydroxylase deficiency. In this case report, the authors discuss when to suspect, how to diagnose, and how to manage similar cases.
RESUMO
There is no evidence of seasonal variation in visits to clinics dedicated to sexually transmitted infections (STIs) in Italy, nor of changes after the advent of the COVID-19 pandemic. An observational, retrospective, multicentric study was conducted to record and analyze all the visits to the STI clinics of the Dermatology Units of the University Hospitals of Ferrara and Bologna and of the Infectious Disease Unit of Ferrara, Italy, between January 2016 and November 2021. Overall, 11.733 visits were registered over a 70-month study period (63.7% males, mean age 34.5 ± 12.8 yrs). The mean number of monthly visits significantly decreased from the advent of the pandemic (136) compared to before (177). In the pre-pandemic period, visits to STI clinics increased in the autumn/winter months when compared to spring/summer, while the trend was the opposite in the pandemic period. Thus, during the pandemic, both an overall significant reduction in visits to STI clinics and a reversal in their seasonality were observed. These trends affected males and females equally. The marked decrease, mostly found in the pandemic winter months, can be linked to the "lockdown"/self-isolation ordinances and social distancing measures during the colder months, coinciding with the spread of the COVID-19 infection, which limited the opportunities for meeting and socializing.
