Sperm parameters were analysed following WHO (2010) guidelines and sperm morphology by Transmission Electron Microscopy (TEM) analysis mathematically elaborated. FSHR and LHR gene mutations have been searched by PCR technique, followed by DHPLC analysis and direct sequencing.

In FSHR, we found no difference in the frequency between Ala or Thr at position 307, Ser was at codon 680 in all subjects. Three patients had an heterozygous mutation at codon 419. Three intronic polymorphisms (rs2091787,

rs6708637, rs1922464) were significantly found compared to controls; the single allele frequency and the odds ratio were calculated. Two new variants: BI-D1870 in vitro the Cys338Arg and the Gln123Glu were detected in two

different patients. Regarding LHR, three patients were heterozygous for the known variant Glu354Lys and two for Ile374Thr. Intronic polymorphisms were not identified. A new variant, the Val144Ile was found. By the routine semen analysis, variable seminal conditions in this group of patients was observed, on the contrary TEM data mathematically elaborated showed a homogeneous decrease in fertility index and increase in sperm pathologies selleck compound such as apoptosis and immaturity.

The obtained results suggest that a deeper examination of spermatozoa, achieved by the use of more powerful tools such as TEM or molecular analysis, are advisable in patients with hypergonadotropic hypogonadism.”
“Osteonecrosis of the jaws is a clinical entity described and linked to treatment with bisphosphonates in 2003. Its real incidence is unknown and it could increase due to the large number of patients treated with these drugs, and its cumulative effect on the bone. State of the art knowledge regarding its etiopathogeny, clinical course and suitable treatments is limited.


To study the clinical characteristics of 44 patients with bisphosphonate-related osteonecrosis of the jaws and the state of their bone mineral metabolism: Selleck AZD2014 bone remodeling state, prevalence of fractures, bone mineral density study, and assessment of the different treatment strategies.

Design of the Study: Observational. Information was gathered prospectively through interviews, clinical examinations, additional tests and review of medical records.

Results: We studied 16 men and 28 women with a mean age of 64.7 years. Breast cancer was the most frequent underlying disease. Zoledronate was used in 82% of the cases and in the non-oncology group of patients; alendronate was the most frequently used bisphosphonate. The mean duration of the zoledronate and alendronate treatments was 25 months and 88 months respectively. The lower jaw was the most frequent location, and previous exodontias-among the triggering factors known-were the most closely linked to its onset.
