Abstract
BACKGROUND There is a lack of autism screening instruments for deaf or hard of hearing (DHH) adults with intellectual disability. AIMS This study examined the diagnostic validity of the Pervasive Developmental Disorder in Mental Retardation Scale and the Diagnostic Behavioral Assessment for autism spectrum disorder - Revised in this rare population. METHODS AND PARTICIPANTS 56 DHH adults with intellectual disability living in three specialized therapeutic communities were examined, 9 of whom met criteria for autism. OUTCOMES AND RESULTS With minimal adaptions regarding item interpretation, both tools showed good diagnostic and high convergent validity. Items probing for difficulties in reciprocal social interaction and restricted interests were discriminant between individuals with and without autism. CONCLUSION These data suggest that both autism screening tools are feasible and psychometrically sound when used with appropriate adaptations for DHH adults with intellectual disability.

Abstract
PURPOSE To analyze and provide an overview of the incidence, management, and prevention of conjunctival erosion in Argus II clinical trial subjects and postapproval patients. METHODS This retrospective analysis followed the results of 274 patients treated with the Argus II Retinal Prosthesis System between June 2007 and November 2017, including 30 subjects from the US and European clinical trials, and 244 patients in the postapproval phase. Results were gathered for incidence of a serious adverse event, incidence of conjunctival erosion, occurrence sites, rates of erosion, and erosion timing. RESULTS Overall, 60% of subjects in the clinical trial subjects versus 83% of patients in the postapproval phase did not experience device- or surgery-related serious adverse events. In the postapproval phase, conjunctival erosion had an incidence rate of 6.2% over 5 years and 11 months. In 55% of conjunctival erosion cases, erosion occurred in the inferotemporal quadrant, 25% in the superotemporal quadrant, and 20% in both. Sixty percent of the erosion events occurred in the first 15 months after implantation, and 85% within the first 2.5 years. CONCLUSION Reducing occurrence of conjunctival erosion in patients with the Argus II Retinal Prosthesis requires identification and minimization of risk factors before and during implantation. Implementing inverted sutures at the implant tabs, use of graft material at these locations as well as Mersilene rather than nylon sutures, and accurate Tenon's and conjunctiva closure are recommended for consideration in all patients.

Abstract
Uveitis, or intraocular inflammation, remains an ongoing challenge to ophthalmologists and patients alike. In most patients, uveitis is limited to the anterior ocular structures and is readily managed with topical steroids. The inflammatory process can extend behind the lens to involve the pars plana, the vitreous cavity, the choroid and the retina. These intermediate and posterior uveitides are relatively rare but contribute disproportionately to visual morbidity and present serious diagnostic and therapeutic difficulties. Systemic steroids constitute the first line of treatment for most sight-threatening uveitides. Their long term use is limited by universal and debilitating adverse effects. Second-line, steroid-sparing agents allow a reduction in steroid dosage. Cyclosporin and azathioprine are the main steroid-sparing agents currently in use. However, these compounds are limited by a narrow therapeutic window and significant adverse effects. This paper offers a brief discussion of some of the immune mechanisms involved in the pathogenesis of uveitis and reviews categories of investigational compounds. Inhibitors of T cell function: tacrolimus (previously FK506), licensed for use in liver transplantation, and sirolimus (rapamycin) are macrolide antibiotics. Sirolimus is a functional cytokine antagonist and in vitro studies suggest it could be up to 100 times more potent than cyclosporin. Drug synergy between sirolimus and cyclosporin has been demonstrated, resulting in immunosuppression at lower drug doses and with fewer adverse effects. Nucleotide synthesis inhibitors: mycophenolate mofetil (MMF) and leflunomide. Human lymphocytes are only able to synthesise nucleic acids de novo. Having no alternative or 'salvage' pathway, they are exquisitely sensitive to interference with the de novo nucleotide synthesis enzymatic pathway. MMF is a purine synthesis inhibitor. Compared to other purine inhibitors, early data suggest that MMF is more efficacious and less toxic than azathioprine. Leflunomide is an inhibitor of pyrimidine synthesis. Monoclonal surface receptor antibodies and immunoadhesins: the IL-2 receptor is essential for clonal expansion of activated T cells; this has led to the development of anti-IL-2 receptor antibodies. Daclizumab is a genetically engineered humanised IgG1 monoclonal antibody. In conjunction with cyclosporin, it significantly reduces renal allograft rejection rates and is also showing promise in the treatment of T cell mediated autoimmune disorders. The mechanism of action of monoclonal antibodies to other pro-inflammatory cytokines such as TNFalpha and IL-12 and data from animal and human uveitis trials are also discussed. Finally, new avenues of research in immunopharmaco-modulation are mentioned.

Abstract
The Argus II 60 channel epiretinal prosthesis has been developed in order to provide partial restoration of vision to subjects blinded from outer retinal degenerative disease. To date the device has been implanted in 21 subjects as part of a feasibility study. In 6 month post-implantation door finding and line tracking orientation and mobility testing, subjects have shown improvements of 86% and 73%, respectively, for system on vs. system off. In high-contrast Square Localization tests using a touch screen monitor 87% of tested subjects performed significantly better with the system on compared with off. These preliminary results show that the Argus II system provides some functional vision to blind subjects.

Abstract
The value of early cleavage (EC) assessment is still being debated. The aim of this prospective study was to examine the predictive value of EC assessment performed exactly 26 h after insemination by IVF or intracytoplasmic sperm injection (ICSI) in a programme of elective single embryo transfer (SET) performed at day 2. If day 2 scoring demonstrated several embryos with high implantation potential, an EC embryo was transferred preferentially. EC was assessed only during normal laboratory hours so that there were two groups: EC assessed, and EC not assessed, the latter being the control. A total of 277 elective SET were performed in women under 37 years undergoing their first IVF or ICSI cycle (mean age 30.5 years, range 21-37). The overall clinical and ongoing pregnancy rates were 40.1% (111/277) and 32.9% (91/277) respectively. Significantly higher overall clinical and ongoing pregnancy rates were obtained after transfer of an EC embryo than a non-EC embryo: 49.4 versus 33.3% (P < 0.05) and 42.4 versus 25.9% (P < 0.02) respectively. However there was no significant difference between the EC assessed and control groups: 40.4 versus 39.3% and 33.2 versus 32.1 respectively. These findings confirm the value of EC assessment for selection of embryos with high implantation potential.

Abstract
The aim of this study was, firstly, to define the different patterns of early cleavage (EC) observed at 26 h after either IVF or intracytoplasmic sperm injection (ICSI) and, secondly, to assess the predictive value of one of these patterns, even EC (EEC), on pregnancy rate in combination with day 2 embryo score. In the first part of the study, the relationship between three different EC patterns (EEC, uneven EC and EC with fragmentation of the day 2 embryo) and embryo morphology was determined. EEC was shown to be strongly associated with good embryo morphology. In the second part of the study, it was shown that EEC used in combination with embryo score improved selection of embryos for transfer. The presence of EEC significantly (P < 0.001) enhanced mean implantation rate in all transfer categories involving identically scored embryos, in both compulsory single embryo transfers and elective single embryo transfers. Multivariate analysis demonstrated that EEC and embryo score had strong complementary predictive value for pregnancy. Based on these findings, it was concluded that even though they are associated, EEC and embryo score could be combined to increase pregnancy rate, especially in elective single embryo transfer programmes.

Abstract
Multiple embryo transfer is associated with a high frequency of twin pregnancies with costly complications involving both mother and child. As a result high priority is currently being given to the development of single embryo transfer (SET) programs. France seems to be lagging behind Northern European countries in the development of SET and widespread use of SET will depend on convincing physicians that this policy will not have a negative impact on success rate, as has been the case for many protocols described in the literature as well as in our own experience. Our SET program includes patients less than 36 years of age undergoing their first FIV-ICSI. If two embryos showing satisfactory morphology are obtained, one is selected transferred and the other is systematically frozen. Selection for transfer is based on two criteria, i.e. observation of even early cleavage 26 hours after FIV-ICSI and evaluation of embryo morphology score on day 2. Embryo morphology score is based on the presence of four blastomeres and absence of blastomere irregularities and anucleated fragmentation. Last, a prerequisite for SET is an effective freezing program. A pregnancy rate of 13% per thawing was sufficient enough to obtain a cumulative pregnancy rate after SET (N = 205) and subsequent frozen embryo transfer (FET) similar to the cumulative pregnancy rate obtained after double embryo transfer (N = 394) and subsequent FET (46.3 vs 46.7%, NS). Twin delivery rate were respectively 2,6% after SET and 26,6% after double embryo transfer (P < 0.01).

Abstract
BACKGROUND In age related macular degeneration and inherited dystrophies, preservation of retinal ganglion cells has been demonstrated. This finding has led to the development of various models of subretinal or epiretinal implant in order to restore vision. This study addresses the development of a polyimide subretinal electrode platform in the dystrophic P23H rat in vivo. METHODS A technique was developed for implanting a subretinal electrode into the subretinal space and stabilising the distal extremity of the cabling on the rat cranium in order to allow future electrical stimulations of the retina. RESULTS In vivo imaging of the retina with the scanning laser ophthalmoscope demonstrated reabsorption of the surgically induced retinal detachment and the absence of major tissue reactions. These in vivo observations were confirmed by retinal histology. The extraocular fixation system on the rat cranium was effective in stabilising the distal connector for in vivo stimulation. CONCLUSION This study demonstrates that a retinal implant can be introduced into the subretinal space of a dystrophic rat with a stable external connection for repeatable electrical measurements and stimulation. This in vivo model should therefore allow us to evaluate the safety and efficacy of electrical stimulations on dystrophic retina.

Abstract
BACKGROUND 360 degrees encirclement for rhegmatogenous retinal detachment (RD) was introduced over 50 years ago as a method for closing retinal breaks and relieving vitreous traction. In the absence of acknowledged guidelines, current usage varies widely. PATIENTS AND METHODS All 360 degrees encircling bands for RDs performed between 1999 and 2004 were reviewed. Encircling procedures for phakic and recurrent RDs were analysed. RESULTS 41 encircling bands for RD were identified from the records of 875 RD cases. Median follow-up was 6 months (range: 1 - 36). Male patients accounted for 58.5 % of the procedures. Mean age was 51.51 +/- 15.97 years. 37/41 phakic and 18/41 recurrent RDs were encircled. RD recurrence in encircled eyes occurred in 42 % of phakic eyes and in 33 % of eyes re-operated for recurrent RD. At the time of recurrence, proliferative vitreoretinopathy (PVR) was present in 41.6 % of phakic eyes, and 66 % of recurrent RD eyes. Preoperative visual acuity (VA) was 0.26 and post-operative VA 0.34. Post-operative complications due to the encirclement included pain in 4 eyes, scleral abscess in 2 eyes and scleral necrosis in 1 eye. CONCLUSION This small retrospective review highlights the multiple indications for encircling bands including PVR, inferior breaks, multiple breaks and myopia. High overall recurrence rate (34 %) reflects the selection bias of this procedure for severe disease in our series. There is currently no consensus on the use of this technique in the management of RD.

Abstract
OBJECTIVE Prevention of twin pregnancies using elective Single Embryo Transfer (e-SET) is now considered by many Assisted Reproductive Techniques teams as a necessity. The aim of this study was to assess the efficacy of e-SET in a prospective manner in a selective population of patients using Take Home Baby Rate per couple as principal parameter. PATIENTS AND METHODS This prospective study was conducted from January 2003 to December 2004. Elective Single Embryo was proposed to women above 37 years in their first IVF or ICSI attempt. It was then performed only in cases when at least one embryo with high implantation potential (score-4 embryo in our embryo scoring) was obtained for transfer and one more (score-3 or score-4 embryo) was available for freezing. RESULTS e-SET was proposed and accepted in 225 couples (25% of eligible couples and 7.8% of total population) and was possible in 96 of these). Two embryos were transferred in all other eligible patients (Double Embryo Transfer group=DET). Cumulative delivery rate after fresh embryo transfers and, if necessary, after frozen-thawed embryo transfers were 39.5% per couple e-SET group and 41.7% in DET group (NS). On the other hand, the percentage of twin pregnancies was significantly different between the two groups (2.6% vs 26.6% respectively; P<0.01). DISCUSSION AND CONCLUSION In women younger than 37 years in their first IVF/ICSI attempt, the elective transfer of only one embryo with high implantation potential strongly allowed to avoid twin pregnancies without any significant delivery rate decrease. This transfer policy is particularly efficient in laboratories displaying good results in their embryo freezing program.

Abstract
BACKGROUND Since 2001, French law has permitted the use of assisted reproductive technology in human immunodeficiency virus (HIV)-1 infected women under strict conditions. This report describes a preliminary series of seropositive women who underwent assisted reproduction treatment at our facility. To minimize contamination of culture media, equipment, and therefore of male gametes and embryos, we chose to perform ICSI in all cases. The outcome of ICSI was compared with the outcome in an age-matched group of non-HIV-1-infected women. Since several previous reports have indicated that HIV infection may be associated with a decrease in spontaneous fertility, our goal was also to assess the fertility status of the HIV-1-infected women entering our ICSI programme. METHODS The French law governing the use of assisted reproduction protocols in HIV-1-infected women was strictly applied. The inclusion criteria were absence of ongoing disease, CD4((+)) count >200 cells/mm(3), and stable HIV-1 RNA level. Since mean age at the time of ICSI was higher in HIV-1-infected women than in the overall group of non-HIV-infected women, we compared outcome data in HIV-1-infected women (group I) to a group of non-HIV-1-infected women matched with regard to age and follicle retrieval period (group II) as well as to the overall group of women who underwent ICSI at our institution (group III). RESULTS A total of 66 ovarian stimulations was performed in 29 HIV-1-infected-infected women. The percentage of cancelled cycles was higher in infected women than in matched controls (15.2 versus 4.9%, P < 0.05). The duration of ovarian stimulation (13.3 versus 11.7 days, P < 0.05) and amount of recombinant FSH injected (2898 versus 2429 IU, P < 0.001) were also higher in infected women. The number of retrieved oocytes, mature oocytes, and embryos obtained as well as embryo quality was similar in all groups. The fertilization rate was higher in infected women than in matched controls (67 versus 60%, P < 0.01). The pregnancy rate was not significantly different between groups I and II (16.1 versus 19.6%) in spite of the fact that the number of embryos transferred was purposefully restricted in the HIV-1-infected group to minimize multiple pregnancy (2.0 versus 2.4, not significant). CONCLUSION The results of this preliminary series of ICSI cycles in HIV-1-infected women indicate that optimal ovarian stimulation is slightly more difficult to achieve than in matched seronegative women. However, when criteria for oocyte retrieval were fulfilled, ICSI results were similar to those of age-matched controls.

Abstract
This prospective study evaluated the crude cumulative delivery rate following delayed intracytoplasmic sperm injection (ICSI) using spermatozoa recovered by testicular extraction (TESE) and intentionally frozen in men with non-obstructive azoospermia (NOA). This procedure can be termed 'cryoTESE-ICSI'. This study involved a series of 118 patients who underwent testicular biopsy for diagnosis of NOA in the period from January 1998 to December 2002. Testicular histology confirmed the diagnosis of NOA. Testicular parenchyma was obtained surgically from both testicles under general anaesthesia. Cryopreservation of spermatozoa was performed in 51 of 118 patients (43%). Ninety-nine delayed ICSI procedures were performed. Frozen-thawed suspensions were used in all cycles. Application of pentoxifylline was required to stimulate spermatozoa in 52% of cases. Fertilization, embryo transfer, and ongoing pregnancy rates were 60, 98 and 29% respectively. The crude cumulative delivery rate was 49% after two cycles and 57% after four cycles. A total of 39 healthy children were born in 29 deliveries. Thus, cryoTESE-ICSI is an effective procedure for routine use in patients with NOA. The main advantages of cryoTESE-ICSI are to (i) avoid repeated surgical biopsy, (ii) ensure the availability of spermatozoa when the ovarian stimulation cycle is begun, and (iii) allow programmed biopsy and therefore dissociate it from ICSI.

Abstract
This paper describes the design of the highest affinity ligands for Grb2 SH3 domains reported so far. These compounds were designed by combining N-alkyl amino acid incorporation in a proline-rich sequence with subsequent dimerization of the peptoid sequence based on structural data and molecular modeling. Optimization of the linker size is discussed, and the N-alkyl amino acid incorporation into both monomeric halves is reported. Because the affinity for Grb2 of the optimized compounds was too high to be measured using the fluorescent modifications that they induce on the Grb2 emission spectrum, a competition assay was developed. In this test, Grb2 is pulled down from a cellular extract by the initial VPPPVPPRRR peptide bound to Sepharose beads. In the presence of competitors, the test quantifies the amount of Grb2 displaced from the beads. It has enabled us to determine a K(i) value in the 10(-10) M range for the highest affinity Grb2 peptoid analogue dimer.

Abstract
AIM To examine epiretinal membranes of proliferative diabetic retinopathy (PDR) for the presence of selective matrix metalloproteinases (MMPs) and their natural inhibitors (TIMPs), in order to determine whether neovascularisation and fibrosis, characteristic of this complication of diabetes mellitus, are associated with specific anomalies of MMP or TIMP expression. METHODS The presence of selected MMPs and TIMPs was investigated in 24 fibrovascular epiretinal membranes of PDR, and the findings compared with that observed in 21 avascular epiretinal membranes of proliferative vitreoretinopathy (PVR) and five normal retinas. Specimens were examined for deposition of interstitial collagenase (MMP-1), stromelysin-1 (MMP-3), gelatinase A (MMP-2), gelatinase B (MMP-9), and three tissue inhibitors of metalloproteinases (TIMP-1, TIMP-2, and TIMP-3). RESULTS The results showed that unlike normal retina, which constitutively expresses MMP-1 and TIMP-2, a large proportion of PDR membranes (> 62%) stained for MMP-1, MMP-2, MMP-3, MMP-9, TIMP-1, TIMP-2, and TIMP-3. There were no differences in the expression of these molecules when compared with PVR membranes. A characteristic staining for MMP-9 was observed within the perivascular matrix of PDR membranes, and there was a significant increase in TIMP-2 expression by PDR membranes (p= 0.036) when compared with PVR membranes. CONCLUSIONS The findings that MMPs involved in degradation of fibrovascular tissue matrix, as well as TIMP-1 and TIMP-2, are found in a large proportion of PDR membranes, and that their expression does not differ from that of PVR membranes, suggest the existence of common pathways of extracellular matrix degradation in pathological processes leading to retinal neovascularisation and fibrosis.

Abstract
PURPOSE Pentoxifylline (PF) has been used to enhance sperm motility in many in vitro fertilization programs. The twofold purpose of this study was to determine whether PF stimulates fresh or frozen epididymal and testicular totally immotile spermatozoa and whether it can be used to select viable spermatozoa for intracytoplasmic sperm injection (ICSI). METHODS To test the effect of PF on motility, 10 samples of totally immotile spermatozoa were incubated for 10 min with 3.6 mM PF. Motility was initiated in all cases (14.8% mean motility after PF treatment of five samples of fresh or frozen epididymal spermatozoa and 13.6% mean motility of five samples of fresh or frozen testicular spermatozoa). To assess PF for selection of viable spermatozoa before ICSI, we compared the outcome of ICSI in 20 cycles using fresh or frozen epididymal or testicular PF-treated immotile spermatozoa and 139 control ICSI using fresh or frozen epididymal or testicular spontaneously motile spermatozoa. RESULTS Fertilization rates were similar in the PF and control groups (45.2% vs. 51.0%). Embryo quality and division stages at the time of transfer were comparable. Six pregnancies occurred in PF-ICSI group (30.0% per cycle vs. 26.6% in control group) including two deliveries of healthy children and four ongoing pregnancies.

Abstract
PURPOSE To report the clinical features and management of two patients with pseudophakic anterior capsule contraction with secondary tractional ciliary body detachments and hypotonous choroidal effusions. METHODS Case reports. RESULTS In two eyes of two patients with pseudophakia, severe anterior lens capsule contraction and tractional ciliary body detachments, anterior capsulotomy (one Nd:YAG laser, one surgical), was followed by resolution of the ocular hypotony and resolution/nonrecurrence of the choroidal effusions. In both cases, continuous curvilinear capsulorhexis was used during cataract surgery. CONCLUSION Anterior capsule contraction following pseudophakia may result in tractional ciliary detachment and secondary ocular hypotony. Radial anterior capsulotomy appeared to be effective in both cases.

Abstract
Diabetic retinopathy remains the most common cause of blindness in people of working age but the provision of high quality eye screening for diabetic patients is still erratic in many health districts in the UK. National consensus guidelines recommend comprehensive population coverage, high sensitivity (>80%), high specificity (>95%), agreed clinical criteria, referral procedures and centralized data collection to facilitate audit. This study looks at the effectiveness of implementing a prompted recall programme for retinal screening in an inner-city district of North London. The scheme uses trained, accredited optometrists to screen patients with diabetes who are looked after in the community by their general practitioner. During the first 17 months of the scheme, 63 optometrists attended training and gained accreditation. Of the 666 patients recruited, 645 were scheduled for screening and 536 (83%) attended. Fourteen per cent of patients screened were found to have background retinopathy and 2.3% sight-threatening eye disease. In two audits, carried out 15 months apart in a random sample of GP practices, the incidence of recorded dilated fundoscopy increased from 48% at baseline to 56%, an increase of 8% (95% CIs 2%-14%). For referable eye disease, the sensitivity of this screening technique was 100%, the specificity 94% (95% CIs 90%-98%), the positive predictive value 79% (95% CIs 72%-86%) and the negative predictive value 100%. The administrative cost per case screened was Pound Sterling 12.60 (excluding clinical costs and any additional optometry payment).

Abstract
AIMS/BACKGROUND To measure aqueous humour levels of brain natriuretic peptide (BNP) and atrial natriuretic peptide (ANP) in humans. To compare peptide levels in glaucomatous and control eyes to test the hypothesis that these peptides are increased in glaucoma. BNP and ANP are cyclic endopeptides whose principal biological effects are natriuresis and vasodilatation. Experimental glaucoma in animal models results in elevated aqueous ANP. Intravenous ANP administration in both animals and humans causes lowering of intraocular pressure (IOP). There are equivocal data to support a role for ANP in IOP regulation in human eyes. There are as yet no published data on BNP in human aqueous humour. METHOD This was a case-control study. Cases were primary open angle, pseudoexfoliation, and mixed mechanism glaucoma eyes undergoing trabeculectomy. Controls were cataract extraction eyes. There were 47 trabeculectomy eyes (44 patients) and 47 cataract extraction eyes (46 patients) matched for age, sex, race, systemic medications, and type of anaesthetic. 100-200 microliters of aqueous humour were aspirated by paracentesis as the first step in the surgical procedure. Peptide levels were later measured by radioimmunoassay. RESULTS The presence of BNP and ANP in human aqueous humour was confirmed. BNP was present in higher concentrations than ANP. BNP levels tended to be greater in control eyes--glaucoma median 56.5 (range 0-3526.5) pg/ml versus control median 65.16 (range 0-1788) pg/ml (Wilcoxon signed rank test p = 0.78). ANP levels tended to be greater in glaucoma eyes than in controls: glaucoma median 3 (range 0-68.5) pg/ml versus control median 0 (range 0-60) pg/ml (Wilcoxon signed rank test p = 0.82). ANP and BNP were log linearly related in both groups (r glaucoma group = 0.961, r control group = 0.894). CONCLUSION This is the first report of BNP and ANP in human aqueous humour. Peptide levels did not differ significantly between glaucoma and cataract extraction eyes. A linear relation between log BNP and ANP was found. Further studies are required to clarify the role of these peptides in aqueous humour production and IOP regulation.

Abstract
The purpose of this study was to retrospectively compare the overall results and embryo quality in 102 cycles of in-vitro fertilization (IVF)-embryo transfer using normal frozen donor semen (group D) and 94 cycles of IVF-embryo transfer using husbands' teratozoospermic sperm (group T). Donor semen was purchased from men with proven fertility and normal semen parameters. Teratozoospermia was defined in group T as the presence of <20% of normal spermatozoa in semen on the day of oocyte retrieval. Exclusion criteria were a sperm count <10 x 10(6)/ml or with <10% progressive motility. Fertilization rate, transfer rate and number of transferred embryos per cycle were significantly lower in the teratozoospermic group (45 vs 72%, 66 vs 96%, 1.7 vs 2.9%, respectively). Pregnancy rate per cycle was also lower, but not significantly (18 vs 28%). However, pregnancy rate per transfer, implantation rate per transferred embryo and take home baby rate were comparable (27 vs 30%, 15 vs 15%, 21 vs 24%, respectively). Similarly, embryo quality in terms of number of embryos displaying fragmentations or irregular cells, cleavage stages and embryo scores were comparable. When group T was divided into two subgroups according to sperm count (group T1: sperm count = 10-20 x 10(6)/ml; group T2: sperm count >20 x 10(6)/ml), there was no difference between them with regard to fertilization rate, pregnancy rate or embryo quality. This study confirms low pregnancy rate per cycle in IVF-embryo transfer using teratozoospermic semen, but demonstrates for the first time that embryo quality and viability are not impaired. It is proposed that the poor pregnancy rate per cycle obtained is due only to the poor fertilization rate, and to the subsequent limited choice of embryos to be transferred.

Abstract
The prognostic value of the score of embryo transfer (SET) was assessed on 1079 embryo transfers in a homogene population of patients. The SET is obtained adding the embryo score (ES) of each transferred embryos. ES is based both on the conventional parameters of embryo morphology, and on the 4-cell stage which is the optimum division stage regarding implantation. The SET is strongly correlated with the pregnancy rate (p < 10-5), and is, with the mean score of transferred embryos (MSTE), the most sensitive and specific parameter of all studied parameters. However, embryo quality seems not to be correlated with miscarriages.

Abstract
The purpose of this study was to devise an embryo score to predict the likelihood of successful implantation after in-vitro fertilization (IVF). Unlike most studies dealing with the influence of embryo stage and morphology on pregnancy, our study was based on single rather than multiple embryo transfers. A total of 957 single embryo transfers were carried out. No delivery was obtained after any of the 99 transfers using 1-cell embryos or embryos obtained after delayed fertilization. In the remaining 858 transfers, the embryos had cleaved. Higher pregnancy rates were obtained with embryos displaying no irregular cells (11.7 versus 6.9%; P < 0.01) and embryos displaying no fragmentation (11.5 versus 8.1%; P < 0.05). The 4-cell embryos implanted 2-fold more often than embryos with more or less cells (15.6 versus 7.4%; P < 0.01). Based on these observations, we devised a 4-point embryo score in which embryos are assigned 1 point each if they (i) are cleaved, (ii) present no fragmentation, (iii) display no irregularities, and (iv) have four cells. Both pregnancy rate and take home baby rate were significantly correlated with embryo score. Each point of this score corresponds to a 4% increase in pregnancy rate. Interestingly, pregnancy rate was significantly lower in women aged > 38 years (8.2 versus 11.4%; P < 0.05), even though embryo quality was similar regardless of age. Single embryo transfer allowed us to define a simple and useful embryo score to choose the best embryo for transfer to optimize IVF and embryo transfer outcome. The use of this embryo score could decrease multiple pregnancies after multiple embryo transfers.

Abstract
We report here the results of a study comparing the quality of the embryos obtained after conventional IVF and after ICSI (respectively 872 and 459 embryos for 184 and 108 cycles). In the ICSI group, the female age was lower than in the IVF group, the oestradiol level on the day of hCG injection was higher, so that the number of retrieved oocytes and the number of mature oocytes. The policy of transfer being the same in the two groups, the mean number of transferred embryos was identical. The percentage of embryos without anucleate fragments, the percentage of embryos without irregularities, the percentage of 1, 2, 3, 4 or 5-cell embryos and the distribution of embryos in the 5 embryo scores were similar. In both IVF and ICSI groups, the transfer score (sum of the embryo scores of each transferred embryo) was higher for the patients who achieved pregnancy.

Abstract
The purpose of this study was to compare visual and computerized assisted semen analysis (CASA) in an in vitro fertilization program. Both methods were performed on the day of 316 oocyte retrievals. CASA was performed using a Hamilton 7.2 device adjusted in accordance with the settings defined by a group of 14 French centers. Despite a few discrepancies, the correlation between visual and CASA sperm counts was significant (p < 0.001), so that between the two total motility assessments. The same correlation (Pearson's test) was observed between the fertilization rate and the parameters obtained by visual analysis and CASA. VAP, VSL, VCL and ALH exhibited threshold values under which the mean fertilization rate was below 50%. This study demonstrates the satisfactory reliability of CASA although it cannot yet replace visual analysis.

Abstract
OBJECTIVE To assess the value of subzonal insemination (SUZI) in cases of total or extreme asthenozoospermia. DESIGN The results of IVF after SUZI were assessed in six cycles (four couples) with documented asthenozoospermia. SETTING Institut de Médecine de la Reproduction, Marseille, France. PATIENTS Four couples underwent six retrieval cycles. In all cases asthenozoospermia was total (100% of immotile spermatozoa) or extreme (5% nonprogressive motility). Oligozoospermia and teratozoospermia were ruled out in all cases. In two cases electron microscopy revealed the absence of the central singlet in the flagellum axonemal complex and in one case a major dysplasia of the fibrous sheath in the flagellum principal piece. RESULTS The overall fertilization rate was 45%. The diploid embryo rate was 33%. Embryo quality was satisfactory. In five of six cycles, three embryos were transferred. Two triplet pregnancies were obtained corresponding to an implantation rate per transferred embryo of 40%. CONCLUSION Total or extreme asthenozoospermia seems to be a good indication for SUZI.
