Turpentine Ointment for the Treatment of Folliculitis: An Open, Prospective, Randomized, Placebo- and Comparator-Controlled Multicenter Trial.

INTRODUCTION: Folliculitis is a painful infection and inflammation of the hair follicles, mostly caused by bacterial, fungal, or, more rarely, viral infections. Turpentine derivatives have been used traditionally to treat various skin infections and could thus also be effective in treating folliculitis. We carried out an open, prospective, randomized, placebo- and comparator-controlled multicenter trial to evaluate the efficacy and safety of an ointment containing pine turpentine oil, larch turpentine, and eucalyptus oil in the treatment of acute folliculitis. METHODS: Seventy outpatients with acute folliculitis were treated with the turpentine ointment, a comparator (povidone iodine solution), or a placebo (Vaseline) for 7 days. Photographs of the affected skin areas were taken by the physicians at four visits and by the patients on a daily basis. Photographs were evaluated by blinded observers. Primary efficacy endpoint was the change in total hair follicle lesion counts. Secondary endpoints included the evolution of the lesion counts in the course of the study, responder rate (improvement of follicle lesions by at least one count), and the patient's global assessment. Safety endpoints were the tolerability of the treatments and adverse event recording. RESULTS: A decrease of follicle lesions counts was detected for both active treatments but not for placebo, but the differences among groups were not statistically significant. As for the secondary endpoints, the ointment showed statistically significant superiority over placebo for the evolution of the lesions during the course of the study (p = 0.017), the responder rate (p = 0.032), and the subjective efficacy assessment by patients (p = 0.029). All treatments were equally well tolerated, with a similar number of treatment-emergent adverse events. CONCLUSION: The turpentine ointment is an effective and safe option for the treatment of folliculitis.

Randomized double-blind controlled clinical trials with herbal preparations of Serenoa repens fruits in treatment of lower urinary tract symptoms : An overview.

In this review, results of randomized double-blind controlled clinical trials (RCTs) with extracts of Serenoa repens fruits at a dose of 320 mg/d for the treatment of lower urinary tract symptoms (LUTS) are assessed. Of the RTCs conducted for up to 6 months, a benefit was seen in three of three RTCs with ethanolic, in eight of nine RTCs with hexane, and in one of two RTCs with CO2 extracts. Of the RTCs conducted for more than 6 months, a benefit was seen in two RTCs with hexane and in one RTC with CO2 extracts, whereas one RTC with an ethanolic, two RTCs with hexane, and one RTC with CO2 extracts did not show positive results. As LUTS are dynamic conditions with strong spontaneous fluctuation over time, the majority of patients might expect improvement of single symptoms and thus of quality of life, particularly as the extracts are well tolerated even in long-term treatment.
