Syphilis and the COVID-19 pandemic: Did the lockdown stop risky sexual behavior?

Restrictive measures to contain the coronavirus disease 2019 (COVID-19) pandemic might produce different effects on other infective diseases, especially those affecting the most intimate sphere of sexuality. The epidemiology of syphilis could reflect the consequences of whether people are avoiding or not risky behaviors. To understand the course of syphilis during the COVID-19 outbreak, we performed a retrospective observational study of all new diagnoses observed at the STDs Service of the Dermatology Clinic at Cagliari, part of the Italian sentinel surveillance system. All incident cases diagnosed during the first 6 months of each year, from 2016 to 2020, thus including the recent lockdown period, were retrieved from the database. Of the 87 cases studied, 18 occurred during the first 6 months of 2020, almost all patients (88%) presenting with early phases of the disease and reporting unprotected sexual intercourses in spite of community containment and social distancing. Comparison with the previous 4 years found no significant statistical differences that hospital access and management limitations had not impaired the management of patients with syphilis. We alert the medical community of the possible increase of sexually transmitted diseases, as society returns to normal.

Pseudoepitheliomatous keratotic and micaceous balanitis: low-risk human papilloma virus detection in two further cases.

We report two cases of histologically documented pseudoepitheliomatous keratotic and micaceous balanitis in middle-aged male patients, which showed positivity for low-risk serotype human papillomavirus DNA. To our knowledge, only one other case has been documented. Further immunohistochemical proliferative markers were performed and compared to literature findings in penile epithelial proliferations. Evolution to invasive verrucous carcinoma has been associated with absence of HPV DNA. Thus, if confirmed by further studies, HPV testing should be included in pseudoepitheliomatous keratotic and micaceous balanitis assessment to address prognosis, and management.

Alopecia as unique clue to syphilis in a patient.

Alopecia is an uncommon manifestation of syphilis, simulating other common forms of hair-loss, but representing a crucial complaint for the patient, who might by converse have not noticed other signs and symptoms of the disease. Esthetic issues undervaluation might prolong illness, and postpone appropriate treatment. A 42-year-old patient, HIV negative, presented with a 2-month history of progressive generalized thinning of the hairs and small non-scarring irregular alopecia patches of the parietal-occipital areas of the scalp. The patient was under sertraline hydrochloride therapy for a recent diagnosis of bipolar disorder, and expressed the concern that the drug was causing the hair-loss. Accurate anamnesis and visiting of the patients revealed asymptomatic pale pink speckles of the trunk and limbs, and a bilateral psoriasis-like palmo-plantar hyperkeratosis, suggestive of secondary syphilis, further confirmed by serology. Specific antibiotic treatment healed all skin and scalp manifestations, but also the moodiness disorders, which allowed complete psychiatric drug dismissing. Skilled expertise and careful patient's examination are the clue to recognize minimal signs of serious systemic disease, such as syphilis, considered disappeared for decades. The risk of minimizing esthetic complaints, such as hair-loss can deceive a not trained eye, or escape in busy daily practice. Physicians should maintain a high level of clinical suspicion to contain the disease burden, especially among heterosexual apparently not at risk patients.
