Frequency of and rationales for the combined use of electroconvulsive therapy and antiepileptic drugs in Austria and the literature.

Our aim was to observe the frequency of combination therapy using antiepileptic drugs (AEDs) and electroconvulsive therapy (ECT) in Austria and the literature, and to provide rationales and recommendations based on clinical and molecular properties. The responsible ECT leaders of eight Austrian departments were contacted for information about combination therapy. A computerized PubMed database search was performed and supplemented by cross-referencing from papers, review articles and psychiatric manuals. The frequency of combination therapy in Austrian departments ranges between 0 and 85.7%. In 17 studies enrolling a total of 189 patients, 87 (46.0%) patients received combination therapy. Of these 87 patients, nine (10.3%) reported adverse effects. ECT and AEDs show overlapping clinical and molecular properties. Combination therapy is an observed reality and, according to the currently available literature, feasible. A comparison of clinical and molecular properties indicates possible augmentative effects, making combination therapy a promising alternative in treatment-resistant cases. But there is still a clear need for prospective case controlled data concerning side effects, safety profiles and effectiveness until it can be recommended.

Improved monitoring of ovarian stimulation using 3D transvaginal ultrasound plus automated volume count.

Two-dimensional transvaginal ultrasound (2D) is typically performed to monitor follicle growth in IVF and to determine the optimal time for administering human chorionic gonadotrophin. However, 2D only provides an approximation of the real volume of follicles and therefore cannot be used to guarantee standards for follicular measurement. The automated measurement of follicular size in three dimensions (3D) using a software programme that identifies and quantifies hypoechoic regions within a 3D dataset might provide an objective, fast, valid and reliable standard for such measurements. A prospective controlled study (group I: 20 patients, 2D; group II: 20 patients, 3D) investigated how the criteria for triggering oocyte maturation that are normally used in 2D compare to the new and more accurate method of measuring follicles using 3D-based automated volume count. Significantly more oocytes were fertilized (group 1: 7.1 +/- 4.5, group 2: 11.5 +/- 6.4; P < 0.03) when using 3D technology and automated volume count. The study assumes that the automated volume count more closely mirrors the biological reality, which means that it can also be used to guarantee the quality standards established by the European Union directive on tissues and cells (2004/23/EC). This new technology therefore holds great promise of becoming the new standard for monitoring follicular growth in IVF.

Blastocyst development after sperm selection at high magnification is associated with size and number of nuclear vacuoles.

Spermatozoa selection at high magnification before intracytoplasmic sperm injection seems to be positively associated with pregnancy rates after day 3 embryo transfers. The aim was to demonstrate an association between the presence of vacuoles in sperm nuclei and the competence of embryos to develop to day 5. Grading of spermatozoa at x 6000-x 12,500 magnification: grade I, no vacuoles; grade II, or=1 large vacuole; grade IV, large vacuoles with other abnormalities. The outcome of embryo development in a group of 25 patients after sibling oocyte injection with the four different grades of spermatozoa showed no significant difference in embryo quality up to day 3. However, the occurrence of blastocyst formation was 56.3 and 61.4% with grade I and II spermatozoa respectively, compared with 5.1% with grade III and 0% with grade IV respectively (P < 0.001). Spermatozoa selection at high magnification using Nomarski interference contrast is useful to identify more precisely the size and the number of nuclear vacuoles that greatly exert a negative effect on embryo development to the blastocyst stage. These observations confirm previous studies pointing to possible 'early and late paternal effects', both of which may have an impact on early embryonic development.

Antimyelin antibodies as a predictor of clinically definite multiple sclerosis after a first demyelinating event.

BACKGROUND: Most patients with multiple sclerosis initially present with a clinically isolated syndrome. Despite the fact that clinically definite multiple sclerosis will develop in up to 80 percent of these patients, the course of the disease is unpredictable at its onset and requires long-term observation or repeated magnetic resonance imaging (MRI). We investigated whether the presence of serum antibodies against myelin oligodendrocyte glycoprotein (MOG) and myelin basic protein (MBP) in patients with a clinically isolated syndrome predicts the interval to conversion to clinically definite multiple sclerosis. METHODS: A total of 103 patients with a clinically isolated syndrome, positive findings on cerebral MRI, and oligoclonal bands in the cerebrospinal fluid were studied. At base line, serum samples were collected to test for anti-MOG and anti-MBP antibodies with Western blot analysis, and the lesions detected by cerebral MRI were quantified. Neurologic examinations for relapse or disease progression (defined as conversion to clinically definite multiple sclerosis) were performed at base line and subsequently every three months. RESULTS: Patients with anti-MOG and anti-MBP antibodies had relapses more often and earlier than patients without these antibodies. Only 9 of 39 antibody-seronegative patients (23 percent) had a relapse, and the mean (+/-SD) time to relapse was 45.1+/-13.7 months. In contrast, 21 of 22 patients (95 percent) with antibodies against both MOG and MBP had a relapse within a mean of 7.5+/-4.4 months, and 35 of 42 patients (83 percent) with only anti-MOG antibodies had a relapse within 14.6+/-9.6 months (P<0.001 for both comparisons with antibody-seronegative patients). The adjusted hazard ratio for the development of clinically definite multiple sclerosis was 76.5 (95 percent confidence interval, 20.6 to 284.6) among the patients who were seropositive for both antibodies and 31.6 (95 percent confidence interval, 9.5 to 104.5) among the patients who were seropositive only for anti-MOG antibodies, as compared with the seronegative patients. CONCLUSIONS: Analysis of antibodies against MOG and MBP in patients with a clinically isolated syndrome is a rapid, inexpensive, and precise method for the prediction of early conversion to clinically definite multiple sclerosis. This finding may be important for the counseling and care of patients with a first demyelinating event suggestive of multiple sclerosis.
