Ticks on the external male genital structures.

Penis and scrotum are very rarely affected by tick bites. We present four cases of involvement of male genitals by ticks belonging to the family Ixodidae. Dermatological examination showed an apparently healthy skin around the tick. Anti-Borrelia burgdorferi antibodies were negative. In all patients the entire body of the tick was delicately removed by means of pliers. Antibiotic therapy was unnecessary.

Anogenital warts treatment options: a practical approach.

Anogenital warts (AGWs) are an important issue for public health centers dealing with Sexually Transmitted Infections. They are epidemiologically relevant, with significant morbidity and an established effective treatment is lacking. In this article, we examine the epidemiological, diagnostic, and therapeutic aspect of the problem in order to give an up to date picture of the situation and a practical clue for the management of AGWs.

HEV and HAV seroprevalence in men that have sex with men (MSM): An update from Milan, Italy.

Hepatitis E virus (HEV) is a feco-orally transmitted pathogen and one of the most common cause of acute hepatitis worldwide. Recent studies in developed countries suggested that a direct human-to-human contact such as for sexually transmitted diseases may play a significant role in the HEV spread. The aim of this study was to investigate the seroprevalence of HEV and HAV in a group of MSM, including subjects HIV, and Treponema infected, in Milan, Italy. The overall anti HEV IgG seroprevalence in MSM was 10.2% (65/636), instead in the control group the detection rate was 5.2% (15/288) (P < 0.05); the anti HAV seroprevalence was 42.8% in MSM, when in the control group the positivity rate was 29.2% (P < 0.05). The rate of coinfection HEV/HAV was 14.6% in MSM and 1% in control group (P < 0.05). In the future, sexual history, HIV status, and STI risk might address specific investigations to prevent spread of pathogens such HEV in MSM, before becoming a substantial public health problem like for HAV outbreaks.

Acneiform eruptions caused by vitamin B12: A report of five cases and review of the literature.

We describe five cases of acneiform eruption caused by vitamin B12 in five females aged 37, 32, 62, 29, and 21 years, respectively. The eruption appeared from 1 week to 5 months after the beginning of the therapy with i.m. or oral vitamin B12. Clinical picture was characterized by papules and pustules located on the face. In three patients, similar lesions were also present on the neck, shoulders, chest, and upper portion of the back. Comedones and cysts were absent. In two patients, serum vitamin B12 levels were very high. Histopathologic examination in one patient revealed an eosinophilic folliculitis. Spontaneous and complete remission was observed in all patients 3-6 weeks after vitamin B12 discontinuation.

Short contact therapy of acne with tretinoin.

The most frequent side effect of topical retinoids is irritant contact dermatitis. It occurs in approximately 85% of patients; the percentage can reach up to 95% in patients treated with tretinoin. Severity of this dermatitis is moderate to severe in approximately 20% of patients. However, 15% of patients stop the treatment with tretinoin because of skin irritation. The authors used tretinoin as short contact therapy (SCT) in mild to moderate acne, in order to try to reduce the incidence and severity of irritant contact dermatitis. They present the final results of a sponsor-free, pilot, open, multicenter study. Seventy-four patients were treated with 0.05% tretinoin cream. It was applied once daily for 30 min. Treatment duration ranged from 8 to 32 weeks (mean duration: 12 weeks). Acne severity and treatment efficacy were evaluated by means of the Global Acne Grading System. A significant clinical improvement (≥50% from baseline) was observed in 41 patients (55.4%). Thirteen patients (17.6%) developed a mild skin irritation. Four patients (5.4%) stopped the treatment because of severe skin irritation. Efficacy of tretinoin used as SCT seems to be superimposable to that of tretinoin used according to standard modality. Tolerability of SCT with tretinoin is very good. This tolerability allows a high adherence of patients to the treatment and it markedly improves compliance.
