Patogenesi dell’endometriosi: aspetti cellulari e molecolari

L'endometriosi è una malattia ginecologica benigna che interessa il 10-15% delle donne in età fertile. Nonostante l'elevata prevalenza e l'importanza sociale della malattia, l'eziopatogenesi dell'endometriosi non è ad oggi completamente nota. L'ipotesi della mestruazione retrograda proposta da Sampson è quella maggiormente accettata, tuttavia la discrepanza tra il frequente reperimento di cellule endometriali refluite in cavità peritoneale e l'effettiva prevalenza di endometriosi sintomatica, suggerisce il coinvolgimento di uno o più fattori predisponenti nella patogenesi nella patogenesi della malattia.

Sigh in Patients With Acute Hypoxemic Respiratory Failure and ARDS

Background Sigh is a cyclic brief recruitment maneuver: previous physiologic studies showed that its use could be an interesting addition to pressure support ventilation to improve lung elastance, decrease regional heterogeneity, and increase release of surfactant. Research Question Is the clinical application of sigh during pressure support ventilation (PSV) feasible? Study Design and Methods We conducted a multicenter noninferiority randomized clinical trial on adult intubated patients with acute hypoxemic respiratory failure or ARDS undergoing PSV. Patients were randomized to the no-sigh group and treated by PSV alone, or to the sigh group, treated by PSV plus sigh (increase in airway pr…

Weaning from mechanical ventilation in intensive care units across 50 countries (WEAN SAFE)

Background: Current management practices and outcomes in weaning from invasive mechanical ventilation are poorly understood. We aimed to describe the epidemiology, management, timings, risk for failure, and outcomes of weaning in patients requiring at least 2 days of invasive mechanical ventilation. Methods: WEAN SAFE was an international, multicentre, prospective, observational cohort study done in 481 intensive care units in 50 countries. Eligible participants were older than 16 years, admitted to a participating intensive care unit, and receiving mechanical ventilation for 2 calendar days or longer. We defined weaning initiation as the first attempt to separate a patient from the ventila…

A randomized comparison of endometrial laser intrauterine thermotherapy and hysteroscopic endometrial resection.

Objective To investigate the difference of long-term amenorrhea rate in patients with menorrhagia treated by endometrial laser intrauterine thermal therapy (ELITT), a new nonhysteroscopic endometrial ablation procedure, versus transcervical hysteroscopic endometrial resection (TCRE). Design Randomized clinical study. Healthy volunteers in an academic research environment. Setting Academic teaching hospital. Patient(s) Premenopausal women with abnormal uterine bleeding. Intervention(s) Fifty-eight patients were treated with the ELITT procedure and 58 patients with TCRE; both groups were treated with GnRH agonists before the procedure. Main outcome measure(s) Bleeding status and patient satis…

Total laparoscopic hysterectomy versus total abdominal hysterectomy: an assessment of the learning curve in a prospective randomized study.

The present randomized study was undertaken in order to compare the short-term results between total laparoscopic hysterectomy and abdominal hysterectomy in a centre with experience in laparoscopic surgery. From January 1997 to September 1998 inclusive, 102 women aged 44-71 years were randomly assigned to either total laparoscopic hysterectomy (n = 51 patients) or abdominal hysterectomy (n = 51 patients). The patients' demographic characteristics were similar in both groups. Average intra-operative blood loss was lower in laparoscopic hysterectomy than in abdominal hysterectomy (P </= 0. 001). The average time employed for laparoscopic hysterectomy was 104.1 +/- 26.98 min; according to the …

Randomized study of subcutaneous low molecular weight heparin plus aspirin versus intravenous immunoglobulin in the treatment of recurrent fetal loss associated with antiphospholipid antibodies.

Objective To compare the 2 most efficacious therapeutic regimens, intravenous immunoglobulin (IVIG) and anticoagulation with low molecular weight (LMW) heparin plus low-dose aspirin, in women with recurrent pregnancy loss associated with antiphospholipid antibodies (aPL). Methods We examined 40 women with recurrent abortion (at least 3 occurrences) and repeatedly positive test results for anticardiolipin or lupus anticoagulant. The subjects were randomly assigned to treatment with IVIG or LMW heparin plus low-dose aspirin. Both therapies were started when the women were pregnant as documented by a positive urine test. IVIG was stopped at the thirty-first week of gestation, aspirin at the th…

IVIG in APS pregnancy

For more than two decades, the intravenous administration of high doses of IgG pooled from the plasma of healthy donors (immune globulin therapy, also known as ‘IVIG’) has benefited patients with a variety of autoimmune disorders. A potential therapeutic role of IVIG in the prevention of thrombosis and of miscarriages in antiphospholipid syndrome (APS) has been postulated. Multicenter randomized controlled trials attempted to define the role of IVIG in preventing pregnancy complications in APS indicate that simple anticoagulation could not be completely satisfactory, and certain patient subgroups might take advantage of IVIG therapy alone or in combination with heparin.
