A Particular Focus on the Prevalence of α- and β-Thalassemia in Western Sicilian Population from Trapani Province in the COVID-19 Era

2023

Thalassemia is a Mendelian inherited blood disease caused by α- and β-globin gene mutations, known as one of the major health problems of Mediterranean populations. Here, we examined the distribution of α- and β-globin gene defects in the Trapani province population. A total of 2,401 individuals from Trapani province were enrolled from January 2007 to December 2021, and routine methodologies were used for detecting the α- and β-globin genic variants. Appropriate analysis was also performed. Eight mutations in the α globin gene showed the highest frequency in the sample studied; three of these genetic variants represented the 94% of the total α-th…

TENSION FREE CYSTOCELE REPAIR. FOUR YEARS FOLLOW-UP

2003

Aims of study: Anterior vaginal wall descensus is one of the most frequent alteration in patients with pelvic defects. At least 50% of women that had delivered two or more times presented a certain degree of this pathologic alteration of the anatomy, even thought only 10-20% of the patients complained of associated pains. The use of synthetic biocompatible materials has become more common in gynecology surgery(1)-(3). Polypropylene mesh to be proposed as a mean of surgical correction of moderate severe cystocele (Cervigni 1998)(2) Methods: 97 patients aged 42-75, parity 1-5, body weight 45-90, menopause 41 pts. (61%).Irritative sintoms( nocturia, frequency, urgency, dysuria and urge inconti…
