Acne is the most common skin disease, with a relative prevalence of 85%-100% among young individuals. It affects the cosmetic appearance of the patients provoking severe distress. A number of different topical treatments have been used for the treatment of acne. In this study, we investigated the efficacy and safety of the topical treatment with 5% benzoyl peroxide and 3% erythromycin gel in patients with papulopustular acne. One hundred and ninety-one patients with inflammatory acne completed the study. The patients included 54 males and 137 females, mean age 22.3±8.1 years. Topical gel was applied on the face once daily for 3 months. The mean number of non-inflammatory and inflammatory lesions after 3 months of therapy decreased significantly with respect to baseline, with a mean percentage reduction of the non-inflammatory and inflammatory lesions by 42.2% and 57.5%, respectively. In conclusion, topical 5% benzoyl peroxide and erythromycin 3% as monotherapy is efficient for the treatment of papulopustular acne.

Angiogenesis leads to new blood vessel formation and is implicated in both physiological and pathological situations. The vascular endothelial growth factor (VEGF) family is the major mediator of this process. The aim of our study was to evaluate the expression of VEGF-A, vascular endothelial growth factor receptor-1 (VEGFR-1) and VEGFR-2 and their correlation with clinicopathological parameters and prognosis in patients with classical Hodgkin lymphoma (cHL), since the role of angiogenesis in this tumor still remains unclear. The immunohistochemical expression of VEGF-A, VEGFR-1 and VEGFR-2 was examined in 194 patients with cHL. The neoplastic Hodgkin Reed-Sternberg (HRS) cells expressed VEGF-A, VEGFR-1 and VEGFR-2 in 90.3%, 97.2% and 94.1% of cases, respectively. Only the expression of VEGFR-2 was positively correlated with serum albumin levels ≥ 4 g/dL. No correlation with patient outcome was observed. All three molecules were statistically correlated with ramifications of blood vessels. Summarizing, our results are not sufficient to consider VEGF-A and/or VEGF receptors as prognosticators in cHL. © 2014 Informa UK, Ltd.

The present study explores nucleotide variability, phylogeny and association with cervical neoplasia in high risk HPV types 16, 18, 31, 33 and 45 collected from Greek women. Of the 1894 women undergoing routine cervical cytology examination, 160 samples test positive for single infections of HPV type 16 (n = 104), HPV 31 (n = 40), HPV 33 (n = 7), HPV 18 (n = 5), and HPV 45 (n = 4) were typed by microarrays method, amplified by PCR then sequenced and phylogenetically analyzed. For HPV 16, 9 variants with nucleotide variations were included into the study. For HPV 31, 33, 18 and 45, nucleotide variations were identified in 6, 4, 2 and 3 variants, respectively. The Bayesian inference and Maximum Parsimony methods were used in order to construct the phylogenetic trees. When types were analyzed independently HPV 16 (European and non-European) and HPV 18 (African and non-African) formed distinct clades. The genomic characterization of HPV variants will be important for illuminating the geographical relatedness and biological differences and for the determination of their risk.
