ABSTRACT
OBJECTIVE: To evaluate the prevalence of human papillomavirus (HPV) sperm infection and its correlation with sperm parameters in patients who attended a fertility clinic. DESIGN: Cross-sectional clinical study. SETTING: University-affiliated reproductive medicine clinic. PATIENT(S): A total of 308 male partners of couples undergoing in vitro fertilization techniques. INTERVENTION(S): Specimens of semen were collected from all patients. MAIN OUTCOME MEASURE(S): Sperm parameters were evaluated according to the World Health Organization manual. The presence of HPV DNA was researched by the combined use of two HPV assays and a highly sensitive nested polymerase chain reaction assay followed by HPV genotyping. To examine whether HPV was associated with the sperm, in situ hybridization (ISH) analysis was performed. RESULT(S): Results of HPV investigation were compared with sperm parameters and ISH analysis. Twenty-four out of 308 semen samples (7.8%) were HPV DNA positive, but HPV infection did not seem to affect semen quality. Moreover, ISH revealed a clear HPV localization at the equatorial region of sperm head in infected samples. CONCLUSION(S): Oncogenic HPV genotypes were detected on spermatozoa from asymptomatic subjects, but a role of the infection in male infertility was not demonstrated.

AIM: The aim of this research is to explore the psychical functioning in bipolar I or bipolar II disorder people through the analysis and comparison of their thought styles and defense patterns. METHODS: 29 bipolar I and bipolar II people afferent to Palermo University Policlinical Psychriatic Hospital Department were selected during the whole 2009-2010 year. The following tests were administred: Wechsler Adult Intelligent Scale-R (WAIS-R) in order to measure the general cognitive function; Defense Mechanisms Inventory (DMI) in order to measure defense patterns. Afterwards, the results of the two tests were analysed and compared. OUTCOME: Bipolar disorder people use cognitive mechanisms and defense strategies that are very different from standard population. Bipolar I subjects show both wider and more serious cognitive deterioration and stricter defense mechanisms than bipolar II subjects. Generally bipolar patients show an immature personality based on archaic mechanisms that can be found in all the spheres of their personality: emotions, cognition, Ego-strength, adaptability to reality. DISCUSSION: The peculiar achieved cognitive and defense profile leads to important considerations about how psychological strategies can contribute to use "bespoke" treatments for these patients.
