Recovery of ovarian function and pregnancy in a patient with AML after myeloablative busulphan-based conditioning regimen

We report a rare case of ovarian function recovery and pregnancy after hormone-replacement therapy (HRT) in the acute myeloblastic leukemia (AML) patient in third complete remission received hematopoietic stem cell transplantation (HSCT) with busulphan-based conditioning regimen. Successful engraftment of the donor cells and full donor's chimerism was achieved without the signs of leukemia. One year after HSCT the patient received a course of HRT as a treatment of hypergonadotropic hypogonadism. After 12 months of HRT the recovery of ovarian function was confirmed. Eight years after the HSCT spontaneous pregnancy occurred; heartbeat of the fetus was registered on week 7. Three weeks later a nonsevere vaginal bleeding occurred and the ultrasound examination showed a nondeveloping pregnancy. Genetic examination of the abortion material showed a full triploid genotype (69 XXX). To our knowledge this is a first case of ovarian function restoration and spontaneous pregnancy in a AML patient after multiple courses of high-dose chemotherapy and busulphan-based myeloablative conditioning for HSCT.     

A Nomogram for Predicting Surgical Complications in Bariatric Surgery Patients

Background  

To minimize morbidity and mortality associated with surgery risks in the obese patient, algorithms offer planning operative strategy. Because these algorithms often classify patients based on inadequate category granularity, outcomes may not be predicted accurately. We reviewed patient factors and patient outcomes for those who had undergone bariatric surgical procedures to determine relationships and developed a nomogram to calculate individualized patient risk.     

Experience with bidirectional cavopulmonary anastomosis and modified Fontan operation in patients with single ventricle and concomitant visceral heterotaxy

The object of our study was to analyze the results of bidirectional cavopulmonary anastomosis (BCPA) and modified Fontan operations (MFO) in patients with a functionally single ventricle and heterotaxy syndrome and to reveal risk factors for these surgical interventions. During 1983-2010, 681 patients underwent BCPA or MFO. Thirty-nine had heterotaxy syndrome. The median follow-up period after BCPA and MFO was nine and 1.5 years, respectively. Risk factors for lethal outcomes were determined by logistic regression analysis. Hospital mortality after BCPA and MFO was 7.9% and 12.5%, respectively and did not significantly differ from patients without heterotaxy. The most frequent hospital complications were heart failure, pleural effusions, and arrhythmias. Late mortality after BCPA and MFO was 8.7% and did not significantly differ from patients without heterotaxy. Late deaths were caused by congestive heart failure or pulmonary thromboembolism. The main non-lethal complication was arrhythmia. Patients have significantly improved their functional class at follow-up. The independent risk factor for lethal outcomes after BCPA and MFO was preoperative regurgitation at atrioventricular valves (P=0.012). BCPA and MFO in patients with a functionally single ventricle and heterotaxy syndrome allow to significantly improves their quality of life. Preoperative regurgitation at atrioventricular valves worsens surgical results.     

Immediate results of bidirectional cavopulmonary anastomosis and Fontan operations in adults

The purpose of this study is to analyze the immediate results of bidirectional cavopulmonary anastomosis (BCPA) and Fontan operations performed in adults, and to reveal the risk factors. During the years 1983-2010, 681 consecutive patients underwent BCPA or a Fontan operation. Fifty-three of 681 patients were more than 18?years of age. Twenty-nine adults underwent BCPA and 24 underwent a Fontan operation. Immediate results of surgical treatment were followed during the hospital period. The average number of exceeded 'operability' criteria by Choussat et al. [Choussat A, Fontan F, Besse P, Vallot F, Chauve A, Bricaud H. Selection criteria for Fontan procedure. In: Anderson RH, Shinebourne EA, editors. Pediatric Cardiology. Edinburgh: Churchhill Livingstone, 1977:559-566] was significantly higher in patients from the BCPA group compared to the Fontan group (1.3±0.8 vs. 0.9±0.7, P=0.034). Hospital mortality after BCPA in adults was 6.9% (2/29) and did not differ from children (7.1%, 19/268), P=0.634. Hospital mortality after Fontan operation in adults was 8.3% (2/24) and did not differ from children (11.9%, 43/360), P=0.419. The frequency of non-lethal hospital complications was higher in patients after a Fontan operation. Patients from the Fontan group more frequently developed arrhythmias and prolonged pleural effusions. Preoperative regurgitation at atrioventricular valves was an independent risk factor for hospital mortality and morbidity after a Fontan operation. BCPA and Fontan operations performed in adults are accompanied by good immediate results and considerably improves patients' condition.
