No full textWe report a 2-year-old girl with an incomplete form of Richner-Hanhart syndrome (tyrosinemia II) whose presenting sign was the appearance of vesicles on the fingertips. In a few months these lesions evolved into typical hyperkeratotic plaques also involving the palms and soles. Photophobia and frequent tearing were observed but there was no intelligence impairment. Serum and urine tyrosine levels confirmed the diagnosis. A low tyrosine and phenylalanine diet permitted good control of the disease with a complete resolution of the oculo-cutaneous symptoms in a month. We emphasize the importance of an early diagnosis of this syndrome to avoid the risk of mental retardation. © 2006 The Authors
Efficacy of Human Papillomavirus Vaccines for Recalcitrant Anogenital and Oral Warts
No full textHuman papillomavirus (HPV) vaccines are preventive measures to decrease HPV infection rates. Knowledge of their efficacy as treatment options for anogenital warts (AGWs) and oral warts (OWs) is limited. To evaluate the efficacy of HPV vaccinations in recalcitrant AGWs and OWs (lesions persisting more than 6 months despite conventional treatments), we compared a group of patients treated with standard therapies plus an HPV vaccine with a group of patients treated with standard therapies only. The response to treatment (in terms of the number of lesions) in the two groups was compared. Data were analyzed with the χ2 test and p values < 0.05 were considered to be statistically significant. The study included 14 patients (group A = cases) who received 3 doses of an intramuscular HPV vaccine (Gardasil 4 or Gardasil 9) in addition to the standard treatments for AGWs and OWs, and 15 age- and sex-matched patients (group B = controls) with an analogous number of lesions to group A who received only standard therapies. After 12 months, 85% of patients of group A versus 33% of group B had positive clinical outcomes (0.004). Our findings suggest a possible therapeutic role of HPV vaccines in addition to standard treatments for AGWs/OWs. Preventive vaccines, blocking the viral entry through the induction of L1-specific antibodies, can prevent autologous reinfections (through auto-inoculation) and favor the elimination of the virus
Treatment of Pediatric Anogenital Warts in the Era of HPV-Vaccine: A Literature Review
No full textAnogenital warts (AWs) represent a therapeutic challenge, especially in infants, due to sensitive skin and frequent disease recurrence. Though the initial wait-and-see approach is often adopted in asymptomatic immunocompetent children, with spontaneous clearing in almost 90% of cases within two years, persistent or symptomatic lesions can be reasonably treated. However, few studies have been conducted on children. Consequently, most treatments on patients under age 12 are not approved by the Food and Drug Administration. Herein, we review possible therapies for pediatric use in AW and report an illustrative case of a two-year-old boy with atopic skin and symptomatic, persistent AWs who was successfully treated with topical podophyllotoxin, without adverse effects or recurrence. Among available therapies for AWs, topical therapies, such as immunomodulating-agents (topical imiquimod 5% and 3.75% cream, sinecatechins 15% ointment) and cytotoxic agents (podophyllotoxin and cidofovir) are considered manageable in children because of their low aggressiveness. In particular, podofillotoxin gel 5% and imiquimod 5% cream have been reported to be safe and efficacious in children. Currently, HPV vaccination is not recommended as a treatment for established HPV infection and AWs, yet a possible therapeutic role of HPV vaccination was recently suggested in the literature and deserves mention
