Outcome and feasibility of elective single embryo transfer (eSET) policy for the first and second IVF/ICSI attempts

Objective

This study assesses the outcome and the feasibility of an elective single embryo transfer (eSET) policy for the first and second IVF/ICSI attempts.

Study design

This is a retrospective analysis performed on 611 couples attempting a first IVF cycle in Clermont-Ferrand University Hospital, France. eSET was offered to the couples when they had 2 embryos with at least one of good quality at day 2 for their first and second IVF/ICSI cycles.

Results

Among the couples selected for the study, 442 underwent an eSET and 341 a double embryo transfer (DET). The cumulative ongoing pregnancy rate (OPR) and the cumulative delivery rate (DR), including fresh and frozen embryo transfer, did not differ statistically between the two groups, respectively 40.7% and 30.9% in the eSET group and 42.5% and 34.6% in the DET group. The twin pregnancy rate was lower in the eSET group (0.7% vs. 21.2%; p < 0.0001) and neonatal and obstetrical outcomes were better than in the DET group. For the first attempt, the global twin rate (including eSET and DET) was 7.1% and the proportion of eSET was high, 67.6%, but for the second attempt the eSET rate was only 16.9%, with an increased global twin rate of 21.4% (p = 0.042).

Conclusion

In a selected population an eSET strategy decreases the twin pregnancy rate without decreasing the delivery rate, with a better outcome for the infants than DET. However, eSET is well accepted by patients only for the first attempt even though the pregnancy rate is not statistically different for the second.     

The diagnosis of cat-scratch-disease-associated adenitis: diagnostic value of serology and polymerase chain reaction

The diagnosis of cat scratch disease (CSD) associated adenitis relies classically on the association of clinical, epidemiological and bacteriological criteria. The polymerase chain reaction (PCR) looks like a more competitive diagnostic trial than serology. We evaluated the sensitivity, specificity and predictive positive and negative values of serology in routine diagnosis of CSD. A retrospective study over five years was led among patients presenting a suspicion of CSD and having a serology and/or a PCR. The Gold standard for diagnosis was PCR. The serological tests of Bartonella henselae was performed once in 482 patients, of which 2% (11 out of 482) were positive, and twice in only 39 patients (8%). The PCR diagnosis method for B. henselae was performed in biopsy of specimen lymph nodes in 28 patients and 14 out of 28 were positive. In nine patients, the diagnosis was exclusively made by PCR. Among the 14 patients whose PCR was negative, two had a positive serology and in three others patients, the serology was not performed. The sensitivity of serology was 35%, this confirms the low sensitivity of the serology in the CSD diagnosis. The diagnosis was confirmed in 56% of cases where PCR was performed. This led us to propose to perform systematically the PCR test for B. henselae in case of adenitis possibly associated with CSD.     

Home intravenous antibiotic treatment of patients with cystic fibrosis

We report one-year's experience of home iv antibiotic treatment in 31 patients with cystic fibrosis chronically colonized with Pseudomonas aeruginosa. The patients were aged 4-67 years and had a mild to severe disease as indicated by a Shwachman score of 46-95 (mean 77). Ninety-two courses of iv antibiotic therapy were given (mean 3.0 per patient). The mean duration of the courses was 15.4 days. The entire antibiotic course, except for the first dose, was administered at home in 70% of the courses. Most patients (94%) were given a combined treatment of a beta-lactam and an aminoglycoside, administered by the patients themselves or their parents. One inserted venous cannula could be used for the whole treatment period in 30% of the courses. There were no complications. The clinical and bacteriological outcome was good to excellent in 89% of the courses, with temporary eradication or semi-quantitative decrease of Pseudomonas growth in sputum. Lung function (forced expiratory volume at 1 s) and blood gases improved significantly (p less than 0.001) and p less than 0.01, respectively). Most patients were able to attend work or school as usual, and 96% of the patients preferred this type of treatment to hospitalization. Apart from the psychosocial advantages, the economical savings were substantial. In comparison to traditional treatments in hospital (21 patients, 41 courses) home iv antibiotic treatment was safe and effective.     

Maternal postures and epidural analgesia during labour

The evolution of birth is of interest for obstetricians and midwives. Postures with asymmetric stretching and balance, kneeling, or sitting have been claimed to be able to help foetal head rotation. Although walking during labour have no influence on the outcome of labour, hip-flexed postures enlarging the pelvic diameter are yet evaluated to improve the obstetric course of labour. In a prospective randomised study including 93 parturients, we compared the supine 30 degrees lateral tilt (control group) to three hip-flexed postures: sitting (S), right hip-flexed left lateral position (L) and left hip-flexed right lateral position (R). Epidural analgesia with 12 ml ropivacaine 0.1% and sufentanil 0.5 microg/ml was administered over a period of six minutes. The total epidural spread was 15+/-0.3 dermatomes and the upper level of thermo-analgesic blockade reached T7-T8 (T5 to T10) in each group. There were no differences between groups for the left and right total spread and upper level of epidural blockade, for the time to maximal block and pain relief. There was no motor block and no maternal or foetal side effects. We conclude that, for the three hip-flexed postures tested, position does not influence local anesthetic spread or symmetry of analgesia after induction of obstetric epidural anaesthesia.     

Hospital and catchment area antibiotic utilization and bacterial sensitivity in primary infections following gastric surgery in Huddinge,Sweden

The relationship between hospital and catchment area utilization of antimicrobial agents and the antibiotic sensitivity of bacteria isolated from primary infections has been studied after 750 gastric operations performed between 1972 and 1986 at the Huddinge University Hospital. Over 80% of the antibiotics were used in the catchment area. Penicillins (G and V) overall were the most commonly used drugs and comprised 37% of the total antibiotic consumption in 1977-1986. Narrow-spectrum antibiotics dominated throughout the period under investigation. No change in the bacterial resistance to antimicrobial agents was found over time. Many strains of Klebsiella/Enterobacter and E. coli resistant to ampicillin and tetracyclines were recovered throughout the period under investigation. No aerobic Gram-negative bacteria were resistant to gentamicin. All Bacteroides strains except two were sensitive to cefoxitin. Tetracyclines and ampicillin/amoxycillin were mainly used in the catchment area, and cefoxitin and aminoglycosides were almost exclusively used in the hospital. Antimicrobial agents primarily used for out-patients in the catchment area seemed to have more influence on the susceptibility of microorganisms isolated from post-operative infections than agents primarily used in the hospital.     

Lobar holoprosencephaly: prenatal MR diagnosis with postnatal MR correlation

Holoprosencephaly is a congenital anomaly characterized by lack of cleavage of the prosencephalon. Although, relatively rare, it is the most common anomaly that involves both the brain and the face. Prenatal diagnosis of this anomaly using ultrasonography, particularly of the less severe forms, is difficult. Magnetic resonance imaging has recently become an important complement to US in prenatal diagnosis of CNS anomalies. We herein report a patient in whom, at 23 weeks of gestation, US suggested agenesis of the corpus callosum and in whom, at 24 weeks of gestation, MRI correctly diagnosed lobar holoprosencephaly, which was confirmed by a postnatal MRI at 3 weeks of age.
