Comparison of clinical performance of Abbott RealTime High Risk HPV test with that of hybrid capture 2 assay in a screening setting.

Randomized trials have produced sound evidence about the efficacy of screening with human papillomavirus (HPV) DNA tests in reducing cervical cancer incidence and mortality. We evaluated the clinical performance and reproducibility of the Abbott RealTime High Risk (HR) HPV test compared with that of the HR hybrid capture 2 (HC2) assay as assessed by a noninferiority score test. A random sample of 998 cervical specimens (914 specimens of cervical intraepithelial neoplasia less severe than grade 2 [

[Critical ischemia of the diabetic patient]. / L'ischemia critica nel paziente diabetico.

BACKGROUND: Critical ischemia of the lower limbs is the final result of diabetic arteriopathy. The surgeon is more and more forced to choose between amputation d emblée and the attempt to revascularization in very old patients and in deficient general conditions. Shall we point out some principle to address our strategy? METHODS: To answer this question we reviewed retrospectively our surgical choices and the results obtained during two years, from January 1997 to December 1998 (medium follow-up 11.3 months), at the Emergency Division of the Cannizzaro Hospital of Catania. In this period 143 diabetic patients were selected by our ambulatory. Of these, nineteen had a critical lower limb ischemia and therefore were submitted to a revascularization and/or amputation. All the revascularized patients were controlled by Doppler-sonography immediately after operation and then daily, till their discharge. Controls were done at the first, third, sixth month and after one year, except for patients who complained a new objective or subjective ischemic symptomatology. RESULTS: The primary patency rate was 84.2% and the secondary patency rate was 89.4%. The amputation rate due to the procedure failure was 5%. The complications were three: two graft infections (10.5%) and one early thrombosis of a femoro-popliteal bypass graft, due to technical defect (5.2%). Perioperative mortality rate was 15.7%. CONCLUSIONS: These results, if related with those reported in the letterature about amputations, are in favour of the attempt to revascularization.

[Permanent endocardiac electrostimulation. Considerations on 511 implantations and reimplantations in 7 years of practice]. / L'elettrostimolazione endocardica permanente. Considerazioni su 511 impianti e reimpianti in sette anni di attività.

Permanent pacemakers were implanted and reimplanted in a total of 511 patients (mostly men) during a period of about 7 yr. Mean age was 67.9 yr. The cephalic route was used in nearly every case, with subclavicular implantation of the generator. Mean hospital stay was 7.6 days. Ventricular inhibition pacemakers were used in over 84% and fixed-frequency models in 7%. Mean pacemaker life was 24.1 months, with longer periods in the last months of the period of observation. The evaluation of battery run-down and recent and long-term complications is discussed, together with a particular type of decubitus of electrolytic origin. Hospital mortality was 2%. Survival was 91% at 1 yr and 54% at 6 yr. Emphasis is placed on the fact that subjects continue to be heart patients. Their well-being depends on psychological and general medical care, together with help from their, families and society, quite apart from cardiological attention.
