Treatment of lower extremity telangiectasias in women by foam sclerotherapy vs. Nd:YAG laser: a prospective, comparative, randomized, open-label trial.

BACKGROUND: Telangiectasias of the lower extremities are very common. There are no blinded, randomized, controlled clinical trials comparing laser modalities with the gold standard sclerotherapy, while the few available studies encompass small patients cohorts. OBJECTIVE: This prospective, randomized, open-label trial compares the efficacy of sclerotherapy with polidocanol vs. long-pulsed neodymium-doped yttrium aluminium garnet (Nd:YAG) laser in the treatment of leg telangiectasias. PATIENTS AND METHODS: Fifty-six female patients with primary leg telangiectasias and reticular veins (C1A or SEpAS1PN) were included in the study. One leg was randomly assigned to get treatment with the multiple synchronized long-pulsed Nd:YAG laser, while the other received foam sclerotherapy with polidocanol 0.5%. The patients were treated in two sessions at intervals of 6 weeks. The patients were evaluated by the handling physician after 6 weeks and 6 months. Two investigators assessed blindly at the end of the study the photographs for clearing of the vessels using a six-point scale from 1 (no change) to 6 (100% cleared). Patients reported about pain sensation and outcome satisfaction. RESULTS: According to the handling dermatologist, at the last follow-up, there was an improvement of 30-40% with a median of 3 (IQR 2) and a good improvement of 50-70% with a median of 4 (IQR 2) after laser treatment and sclerotherapy respectively. In contrast, according to the blinded investigators, there was a median of 5 (IQR 1) with a very good improvement of >70% after both therapies. Improvement was achieved more quickly by sclerotherapy, although at the last follow-up visit there was no difference in clearance between the two groups as assessed by the blinded experts (P-value 0.84). The degree of patient's satisfaction was very good and similar with both therapeutic approaches. There was a significant difference (P-value 0.003) regarding pain perception between the types of therapy. Laser was felt more painful than sclerotherapy. CONCLUSION: Telangiectasias of the lower extremities can be successfully treated with either synchronized long-pulsed Nd:YAG laser or sclerotherapy. The 1064-nm long-pulsed Nd:YAG laser is associated with more pain and is suitable especially in case of needle phobia, allergy to sclerosants and in presence of small veins with telangiectatic matting, while sclerotherapy can also treat the feeder veins.

Compression hosiery for occupational leg symptoms and leg volume: a randomized crossover trial in a cohort of hairdressers.

OBJECTIVE: Occupational leg symptoms are highly prevalent in the general population and impair the psychic state of health. We investigated hairdressers, a cohort exposed to prolonged standing during work, in a randomized crossover trial. We hypothesized that hairdressers wearing low-strength compression hosiery would benefit from less leg volume increase and discomfort. METHODS: One hundred and eight hairdressers were randomized to wear medical compression stockings (MCS; 15-20 mmHg) in a crossover study. The effect of MCS on symptoms and on lower leg volume was compared with no compression treatment. Symptoms were assessed with a comprehensive questionnaire, categorized using factor analysis with varimax rotation and correlated with leg volume changes. RESULTS: Wearing MCS reduced the symptom score for pain and feelings of swelling (range 0-4) by an average of 0.22 (12%, P < 0.001). Sleep disturbance, feeling of unattractive legs and depressiveness improved with MCS compared with no MCS. Subjects initially obliged to refrain from wearing stockings showed a significant decrease of pain and feelings of swelling as well (by 0.10 [6%], P = 0.015). Wearing MCS was associated with a decrease of lower leg volume by an average of 19 mL (P < 0.001), with preference in older hairdressers (P < 0.001). The effects of wearing MCS on symptoms and on leg volume were not correlated with each other. CONCLUSIONS: Individuals working in a standing profession experience leg pain, feelings of swelling, heaviness and various other disturbing feelings. These symptoms can be alleviated by wearing low-strength MCS.

[HPV type 16-associated anal intraepithelial neoplasia (AIN)]. / HPV-Typ-16-assoziierte anale intraepitheliale Neoplasie (AIN).

A 25-year-old woman had suffered from a perianal ulcer for approximately 1 year. Topical and systemic treatments had been unsuccessful. Employing virologic and histologic techniques, we confirmed the diagnosis of an intraepithelial neoplasia. Anal intraepithelial neoplasia (AIN) is induced by carcinogenic human papillomaviruses. It can occur anywhere in the anogenital area. Because of its frequency, AIN is a crucial differential diagnosis for lesions of the anogenital area region failing to respond to standard therapies.

[Lichen planopilaris. Successful treatment with tacrolimus]. / Lichen planopilaris. Therapieerfolg mit Tacrolimus.

BACKGROUND: Lichen planopilaris (LPP) is an inflammatory condition of unknown etiology that affects pilosebaceous units, mainly of the scalp, and results in scaring alopecia. OBJECTIVE: A 51-year-old male presented with a pruritic eruption on the cheek consisting of atrophic macules and erythematous folliculocentric papules. RESULTS: Biopsy revealed a perifollicular lymphocytic infiltrate and vacuolar degeneration of the dermoepidermal junction consistent with LPP. Many treatment modalities have been utilized, with varying degrees of success. Our patient responded poorly to topical steroids. After nine months of topical tacrolimus therapy, his lesions resolved entirely. CONCLUSION: The treatment of our patient demonstrates tacrolimus as a novel topical therapeutic option for patients with LPP.
