Penile cancer is an uncommon malignancy. Surgical treatment is inevitably mutilating. Considering the strong impact on patients＇ sexual life we want to evaluate sexual function and satisfaction after partial penectomy. The patients in this study （n = 25） represented all those who attended our institutions and were diagnosed and treated for penile cancer from October 2011 to November 2013. All patients underwent partial penectomy and followed-up （mean： 14 months; range： 12-25）. Sexual presurgical baseline was estimated using the International Index of Erectile Dysfunction 15 （IIEF-15）. Sexual outcomes of each patient were estimated considering four standardized and validated questionnaires. We analyzed the means and ranges of IIEF-15 including erectile function （IIEF-1-5 and -15）, orgasmic function （IIEF-9 and -10）, sexual desire （IIEF-11 and -12）, intercourse satisfaction （IIEF-6-8）, and overall satisfaction （IIEF-13 and -14）. Then, we also used Quality of Erection Questionnaire （QEQ）, Erectile Dysfunction Inventory of Treatment Satisfaction （EDITS） and Self-Esteem and Relationship （SEAR） to evaluate the sexual function and satisfaction of our patients. The final results showed that penile cancer leads to several sexual and psychosexual dysfunctions. Nevertheless, patients who undergo partial penectomy for penile cancer can maintain the sexual outcomes at levels slightly lower to those that existed in the period before surgery.

We investigated central Mediterranean Pinus halepensis plantations under semi-arid climate in order to evaluate the combined effect of soil treatment and afforestation practices on spontaneous plant species composition, richness and evenness, and on the trend and speed of vegetation dynamics. Phytosociological releves of three different plot typologies, i.e. （1） soil-treatment and plantation, （2） only soil-treatment, （3） no soil-treatment and no plantation, were compared by （a） multivari- ate analysis and （b） with reference to species richness and evenness. Moreover, in order to compare vegetation dynamics within the planta- tions with those ones ongoing in semi-natural garrigue communities, we compared life form and syntaxonomic spectra between phytosociological relev6s taken at 8 years of distance. DCA showed that floristic species composition and similarity are influenced by the canopy cover of Pine trees as well as by soil-treatment practices. Although species richness and evenness are not clearly related to neither soil treatment nor Pine afforestation, canopy cover clearly plays a major role： in fact, the highest Ph cover rates correspond to the lowest values of understory species richness. This is true also if only species of biogeographical/conservation interest are considered. Regarding vegetation dynamics, sites with dense Pine canopy cover evolve much slower than the adjacent garrigue communities. The same factors invoqued to explain the patterns of floristic composition and similarity （i.e. allelopathy and competition for light, water and nutrients） may also explain the lowering of diversity of therophytes and the strong decline of the cover perfomed by both therophytes and hemicryptophytes underneath the canopy of dense Ph plantations. Thus, in sites where Ph cover exceeds about 80%, thinning is recommended not only in order to accelerate succession, but also to give a natural ＇shape＇ to afforestations.
