Micronutrients in support to the one carbon cycle for the modulation of blood fasting homocysteine in PCOS women.

PURPOSE: Fasting blood homocysteine is increased in PCOS women and is involved in several of its co-morbidities including cardiovascular disease and infertility. Corrective interventions based on the administration of supra-physiologic doses of folic acid work to a low extent. We aimed to test an alternative approach. METHODS: This was a prospective, randomized, parallel group, open label, controlled versus no treatment clinical study. PCOS women aged > 18, free from systemic diseases and from pharmacological treatments were randomized with a 2:1 ratio for treatment with activated micronutrients in support to the carbon cycle (Impryl, Parthenogen, Switzerland-n = 22) or no treatment (n = 10) and followed-up for 3 months. Fasting blood homocysteine, AMH, testosterone, SHBGs, and the resulting FTI were tested before and at the end of the follow-up. RESULTS: The mean baseline fasting blood homocysteine was above the normal limit of 12 µMol/L and inversely correlated with SHBG. AMH was also increased, whereas testosterone, SHBG, and FTI were within the normal limit. The treatment achieved a significant reduction of homocysteine, that did not change in the control group, independently of the starting value. The treatment also caused an increase of AMH and a decrease of SHBGs only in the subgroup with a normal homocysteine at baseline. CONCLUSIONS: In PCOS ladies, blood homocysteine is increased and inversely correlated with the SHBGs. Physiologic amounts of activated micronutrients in support to the carbon cycle achieve a reduction virtually in all exposed patients. Whether this is of clinical benefit remains to be established.

Prophylactic arterial catheterization in the management of high risk patients for obstetric haemorrhage.

OBJECTIVES: Post-partum haemorrhage still remains one of the major causes of maternal morbidity and mortality. In case of abnormal placentation it is possible to carry out preventive and therapeutic actions. To maintain fertility in reproductive-aged women and to avoid a more radical surgery, embolization has been introduced in patients at high risk for haemorrhage. To describe a new option in the management of patients with abnormal placentation by an elective, preventive arterial catheterization and selective embolization of pelvic arteries. PATIENTS AND METHODS: A retrospective study including thirty six patients with abnormal placental invasion. All patients were prepared in the angiographic room and preventive arterial catheterization was performed before elective caesarean delivery. Materials for interventional angiography were transferred to the operating room. During surgery, selective embolization of pelvic arteries was realized in case of uncontrolled bleeding. RESULTS: Thirty-six elective arterial catheterizations were performed: 4 cases (11.1%) required embolization, haemorrhage was stopped in 2 patients. Hysterectomy was performed in two cases (5.5%). No death was reported. Two humeral thrombosis (5.5%) were registered. CONCLUSIONS: Prophylactic arterial catheterization appears to be safe. The main advantage is the reduction of the interval between the onset of bleeding and the embolization. This new option of management may contribute to reduce the risk of hysterectomy and maternal death.

Postpartum hysterectomy: a regional multicentre analysis in Italy.

To estimate prevalence, indications, risk factors and complications associated with emergency postpartum hysterectomy and to compare different results in Teaching and District Hospitals we designed a retrospective analysis in 34 cases of postpartum hysterectomy performed from 1 January 2002 to 31 December 2006, in three different obstetrics and gynaecology units (one University Hospital and two Regional Hospitals). The prevalence of postpartum hysterectomies was 2.2 per 1,000 deliveries. District Hospitals revealed a significantly increased risk (OR: 2.28). Severe complications were few. No deaths were reported. Considering the totality of patients and cases of District Hospitals, placenta praevia was the main cause of hysterectomy (44.1% and 52.2%, respectively), but uterine atony had a major prevalence in the Teaching Hospital (45.4%). Operating time was significantly longer (p = 0.0001) and the blood loss was significantly more important (p = 0.041) in the Teaching Hospitals.
