Abstract
BACKGROUND Elevated neutrophil count is associated with poor prognosis and increased mortality in many conditions. Neutrophil to lymphocyte ratio (NLR) has emerged as a marker of inflammation in neoplastic and cardiovascular disorders. Herein, we investigated utility of this simple tool in rheumatoid arthritis (RA) and ankylosing spondylitis (AS). METHODS The study consisted of 136 RA and 140 AS patients, along with 117 healthy control subjects. RA and AS activities were determined with Disease Activity Score (DAS) and Bath Ankylosing Spondylitis Disease Activity indices (BASDAI), respectively. The association between NLR and disease activity was analyzed. RESULTS Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and neutrophil counts were significantly higher in RA and AS patients compared to healthy controls. Similarly, NLR was higher compared to control subjects, both in RA (2.53 ± 1.4 vs. 2.16 ± 1.0, P = 0.019) and AS (2.43 ± 1.4 vs. 2.16 ± 1.0, P = 0.077). NLR correlated well with ESR and CRP, both in RA and AS. Moreover, NLR increased across worsening DAS28 activity groups (2.1 ± 1.0 in patients with remission, 2.5 ± 1.0 in low-moderate, 3.8 ± 2.5 in high disease activity). However, no association was found between NLR and BASDAI. CONCLUSION NLR is a cheap and readily available marker for the assessment of disease activity in RA.

Abstract
In this study, we compared the fertilization rate and embryo quality after intracytoplasmic sperm injection (ICSI) as they relate to oocyte morphology. A total of 654 ICSI cycles yielding 5903 metaphase II oocytes were observed. The oocytes retrieved in these cycles were divided into (i) normal oocytes, (ii) oocytes with extracytoplasmic abnormalities (dark zona pellucida and large perivitelline space), (iii) oocytes with cytoplasmic abnormalities (dark cytoplasm, granular cytoplasm, and refractile body), (iv) oocytes with shape abnormalities, and (v) oocytes with more than one abnormality (double and triple abnormalities). Intracytoplasmic vacuoles and aggregates of smooth endoplasmic reticulum were not recorded separately. The fertilization rate and quality of morphologically graded embryos did not differ between the groups. There were 77 cycles where all transferred embryos were derived from abnormal oocytes, and 164 cycles where all embryos were derived from normal oocytes. These cycles were studied further. The two groups were comparable regarding mean female age, duration of infertility, duration of ovarian stimulation, number of ampoules of gonadotrophin injected, and number of oocytes retrieved. Two clinical pregnancy rates (44.4 versus 42.1%) and implantation rates per embryo (10.3 versus 13.2%) were similar. In conclusion, in couples undergoing ICSI, abnormal oocyte morphology is not associated with a decreased fertilization rate or unfavourable embryo quality. Furthermore, embryos derived from abnormal oocytes yield similar clinical pregnancy and implantation rates when transferred compared with embryos derived from normal oocytes.

Abstract
OBJECTIVE To determine the relationship between blastocyst quality and the results of embryo transfer at the blastocyst stage. DESIGN Retrospective case analysis. SETTING Tertiary care private hospital IVF center. PATIENT(S) A total of 350 blastocyst-stage embryo transfer cycles. INTERVENTION(S) In vitro culture to the blastocyst stage was undertaken in 350 ICSI cycles where four or more cleavage-stage embryos were available on day 3. MAIN OUTCOME MEASURE(S) Relationship between blastocyst quality and implantation and clinical and multiple pregnancy rates. RESULT(S) Transfer of at least one grade 1 or grade 2 blastocyst or one hatching blastocyst was associated with very high implantation and pregnancy rates. However, transfer of grade 3 blastocysts yielded very low implantation and pregnancy rates. CONCLUSION(S) There appears to be a strong correlation between blastocyst quality and success of blastocyst transfer.

Abstract
BACKGROUND Embryo quality may be accurately assessed as early as the pronuclear zygote phase, as shown in recent studies. However, it is not known whether good quality zygotes are destined to become good quality cleavage stage embryos and blastocysts. METHODS In this retrospective study, 86 intracytoplasmic sperm injection-embryo transfer cycles were studied where each available embryo was scored from the zygote until the blastocyst stage. Embryonic normality parameters such as pronuclear pattern, early cleavage, cleavage stage embryo grade, the presence of embryos with > or =8 cells on day 3 and blastocyst quality were recorded. Embryo transfer was undertaken at the blastocyst stage and the outcome was studied according to the pronuclear pattern exhibited by the zygotes. RESULTS Embryos that showed an ideal pronuclear pattern (0 PN pattern) cleaved earlier and faster and resulted in better quality cleavage stage embryos and blastocysts. The incidence of blastocyst formation was 72% in zygotes showing a 0 PN pattern, compared with 12.7% in zygotes with double pronuclear abnormality. Higher implantation and pregnancy rates were obtained when at least one blastocyst derived from a 0 PN pattern zygote was included in the set of embryos to be transferred. CONCLUSIONS Our results indicate that the pronuclear pattern of the zygote is closely related to blastocyst formation and quality. Blastocysts derived from 0 PN zygotes have a higher potential for implantation.

Abstract
BACKGROUND The pathology underlying recurrent implantation failures (RIF) is not clear and treatment options proposed are generally not evidence based. Although the effect of heparin on trophoblast biology has not been studied extensively, given the available data suggesting a possible beneficial effect of heparin on embryo implantation, we decided to undertake this pilot study. METHODS One hundred and fifty women with > or =2 failed assisted reproduction treatment cycles were included in this randomized open-label pilot trial. Participants underwent controlled ovarian stimulation with the long protocol and were randomly allocated to receive 1 mg/kg/day low molecular weight heparin (LMWH) or no treatment in addition to routine luteal phase support (LPS) on the day after oocyte retrieval. LPS and LMWH was continued up to the 12th gestational week in pregnant participants. RESULTS There were 26 (34.7%) live births in the LMWH group, and 20 (26.7%) in the control group (absolute difference 8.0%, 95% CI -4.2 to 24.9%, P = 0.29). There were 34 (45.3%) and 29 (38.7%) clinical pregnancies in the LMWH and control groups, respectively (absolute difference 6.6%, 95% CI -9.0 to 21.8%, P = 0.41). Implantation rates were 24.5 and 19.8% in the LMWH and control groups, respectively (absolute difference 4.7%, 95% CI -4.7 to 14.1%, P = 0.33). CONCLUSION Despite lack of statistical significance, observed relative increase by 30% in live birth rates with LMWH may be regarded as a clinically significant trend necessitating further research on the use of empirical LMWH in women with RIF and possibly in all women undergoing assisted reproduction treatment. Failure to demonstrate statistical significance of the observed treatment difference may be due to limited sample size of this pilot study.

Abstract
Recent studies indicate a strong paternal influence on embryo development and progression of the embryo to the blastocyst stage. The aim of this study was to compare, during extended culture, the in-vitro development of embryos resulting from intracytoplasmic sperm injection (ICSI) of ejaculated spermatozoa (group 1, n = 347), epididymal (group 2, n = 22) or testicular (group 3, n = 18) spermatozoa from obstructive azoospermic and testicular spermatozoa from non-obstructive azoospermic (group 4, n = 31) subjects. Fertilization and blastocyst formation rates were significantly lower in group 4 (P < 0.05). The incidence of expanded and hatching blastocysts was significantly lower in group 4 (P < 0.05). Overall in 93.2% ejaculate ICSI cycles, blastocysts were transferred on day 5. This was significantly higher than the 62% day 5 transfers in the non-obstructive azoospermic group (P < 0.05). Implantation rate per embryo was significantly higher in the ejaculate ICSI group compared with the other groups (P < 0.05). Clinical pregnancy per transfer was similar between groups; however, significantly fewer multiple pregnancies were encountered in the non-obstructive azoospermic group (P < 0.01). In conclusion, the source of the spermatozoa, most likely to be indicative of the severity of spermatogenic disorder, affects the rate of blastocyst formation and blastocyst implantation. Spermatozoa from non-obstructive azoospermic subjects, when utilized for ICSI, result in embryos that progress to the blastocyst stage at a lower and slower rate and implant less efficiently.

Abstract
The aim of this study was to evaluate whether the extraction of testicular spermatozoa with percutaneous versus open biopsy has an effect on the treatment outcome with intracytoplasmic sperm injection (ICSI) in men with non-obstructive azoospermia. Regardless of testicular size, follicle stimulating hormone concentration, and previous biopsy result, percutaneous testicular sperm aspiration (PTSA) using a 21-gauge butterfly needle was attempted first and if this failed testicular sperm extraction (TESE) was performed. In 63 men spermatozoa were found with PTSA whereas in 228 men TESE had to be undertaken. More men in the PTSA group had previously been diagnosed with hypospermatogenesis (82 versus 50%). Compared with the PTSA group, more men in the TESE group had germ cell aplasia (27 versus 10%) or maturation arrest (22 versus 8%). There was no difference between the groups regarding mean age of men and their partners, duration of stimulation, oestradiol concentration on the day of human chorionic gonadotrophin, number of oocytes retrieved, fertilization rate, and embryo quality between the two groups. The number of embryos transferred (4.38 versus 3.90) was significantly higher in the PTSA group (P < 0.05), reflecting the increased number of embryos available for transfer. Implantation rate per embryo was 20.7% in the PTSA and 13.3% in the TESE group (P < 0.05). Clinical pregnancy rates were 46 and 29% in the PTSA and TESE groups respectively (P < 0.05). Clinical abortion rates were similar (21.2 versus 24%). It is concluded that in men with non-obstructive azoospermia, easier sperm retrieval, which is most likely indicative of a more favourable histopathology, is associated with higher implantation rates per embryo.

Abstract
PURPOSE The aim was to evaluate the effect of aspirin on pregnancy and implantation rates in an unselected group of patients undergoing intracytoplasmic sperm injection (ICSI). METHODS Two hundred and seventy-nine patients were randomized to receive 80 mg of aspirin (n = 139) or no treatment (r = 136) starting from the first day of controlled ovarian hyperstimulation. RESULTS Duration of stimulation, gonadotropin consumption, peak estradiol, number of oocytes retrieved, fertilization rate, cleavage rate, and number of embryos transferred were similar in the two groups. Implantation and clinical pregnancy rates were 15.6% and 39.6% versus 15.1% and 43.4% in aspirin treated and untreated groups, respectively (P > 0.05). CONCLUSIONS Low-dose aspirin administration does not improve implantation and pregnancy rates in an unselected group of patients undergoing ICSI.

Abstract
OBJECTIVE To determine the feasibility and success of blastocyst-stage embryo transfers in patients having only fair and poor quality cleavage-stage embryos on day 3. DESIGN Prospective case study with historic controls. SETTING Tertiary care private hospital IVF center. PATIENT(S) A total of 158 day 5 embryo transfer cycles in patients with grade 3 and grade 4 cleavage-stage embryos. Control group consisted of 162 day 3 transfer cycles performed with embryos of similar quality. INTERVENTION(S) In vitro culture of embryos up to the blastocyst stage. MAIN OUTCOME MEASURE(S) The percentage of cycles that culminated in the transfer of at least one blastocyst and implantation and pregnancy rate related to the day of transfer. RESULT(S) In the day 3 transfer group, a mean of 5.2 embryos were replaced per patient. This was significantly more than the mean of 2.4 embryos that could be replaced on day 5 (P <.001). The clinical pregnancy rate per embryo transfer was 27.2% and 33.5% in the two groups, respectively (P >.05). The implantation rate per embryo was significantly higher in the day 5 transfer group (15% vs. 5.9%). The multiple pregnancy and abortion rates were similar between the groups. CONCLUSION(S) Transfer of fair and poor quality embryos at the blastocyst stage is feasible and is associated with higher implantation rates as compared to transfer of similar quality embryos on day 3.

Abstract
OBJECTIVE To evaluate the association between serum P levels on the day of hCG administration and the outcome of intracytoplasmic sperm injection (ICSI). DESIGN Retrospective case study. SETTING Assisted reproduction unit of a tertiary care private hospital. PATIENT(S) Nine hundred eleven ICSI cycles that proceeded to ET were studied. INTERVENTION(S) The decision to administer hCG was based on serum E2 levels and follicle size. Serum P was measured from frozen sera obtained on the day of hCG administration. Cycles were stratified according to serum P levels of <0.9 ng/mL (n = 298) or > or =0.9 ng/mL (n = 613). This cutoff level was selected because it yielded the highest sensitivity and specificity according to a receiver operator characteristic curve. MAIN OUTCOME MEASURE(S) Implantation and clinical pregnancy rates. RESULT(S) In cycles with high serum P levels, more oocytes were retrieved and more embryos were available for transfer. Clinical pregnancy rates per ET in the low and high P groups were 36.9% and 45.4%, respectively (P<.05). The implantation rate per embryo was similar in the two groups (14.9% and 16.4%, respectively, in cycles with P levels <0.9 vs > or =0.9 ng/mL). Abortion rates were 22.7 and 25.8%, respectively (P>.05). CONCLUSION(S) Our data showed no adverse effect of high serum P levels on the day of hCG administration on implantation rates after ICSI and ET.

Abstract
BACKGROUND Premenstrual syndrome (PMS) is defined as the disabling and cyclic occurrence of emotional and behavioral symptom complex during the latter half of the menstrual cycle. Although its etiology is unknown, it has been speculated that premenstrual syndrome is linked to a deficiency of central serotoninergic activity. METHOD The study consisted of a double-blind, placebo controlled trial of fluoxetine at a dose of 20 mg/day or placebo for three menstrual cycles. The 440 women who appeared to meet the eligibility criteria were instructed to record the 'Calendar of Premenstrual Experiences' (CPE) scale for two complete menstrual cycles. Of 410 women who successfully completed two cycles of recording their symptoms daily only 35 met the criteria for PMS. These criteria included psychiatric interviews which were made before treatment. Thirty-five PMS patients were randomized into placebo or fluoxetine treatment groups. RESULTS Our study suggests that fluoxetine at a dose of 20 mg per day was significantly superior to placebo in alleviating the symptoms of PMS. The most common side effects were gastrointestinal irritability (15%), insomnia (11%) and sexual dysfunction (8.5%). CONCLUSION Fluoxetine is an effective and well-tolerated drug and appears to have considerable promise in treating a range of symptoms in women with PMS.

Abstract
The aim of this study was to determine the effect of 24-h in-vitro culture of testicular spermatozoa in recombinant follicle stimulating hormone (recFSH) supplemented medium versus simple medium on sperm motility, and to analyse the outcome of intracytoplasmic sperm injection (ICSI) of such spermatozoa. A total of 143 positive testicular sperm extraction procedures in men with non-obstructive azoospermia was evaluated prospectively. Extracted testicular tissue samples were randomized to be cultured in vitro for 24 h in simple medium or recFSH supplemented media. ICSI was performed with spermatozoa cultured in recFSH (n = 73) or in simple medium (n = 70). Sperm motility following in-vitro culture, embryo quality after ICSI, and implantation and pregnancy rates were assessed. Of the 898 MII oocytes available in the recFSH group, 646 (71.9%) were injected with spermatozoa showing either twitching or progressive motility. However, only 29.1% of the oocytes in the simple medium group (245/841) were injected with motile spermatozoa (P < 0.05). Fertilization rate (68.8 versus 42.1%), implantation rate per embryo (20.1 versus 13.2%), and clinical pregnancy rate (47. 9 versus 30%) were significantly increased in the recFSH group compared with the simple medium group respectively (P < 0.05). In conclusion, in-vitro culture with recFSH appears to increase the motility of testicular spermatozoa, thus increasing the success of ICSI.

Abstract
We designed prospective studies to compare manual and computerized analysis of sperm morphology by strict criteria using different semen processing and staining techniques. A total of 54 semen samples were studied; slides were prepared from each subject from liquefied semen and after washing, and stained with Diff-Quik or Papanicolaou. An intra-laboratory, blind assessment was performed manually (two observers) and using a computerized analyser (two readings). This demonstrated a very good correlation between manual analysis of liquefied and washed samples with both staining techniques [intraclass coefficient (ICC) = 0.93 and 0.83]. Greater agreement was observed between computerized readings (washed samples) of Diff-Quik (ICC = 0.93) than of Papanicolaou-stained slides (ICC = 0.66). An excellent intra-laboratory correlation was observed for within-computer readings (ICC = 0.93). There was moderate agreement between inter-laboratory computer readings (two centres, ICC = 0.72). Although there was lower inter-laboratory agreement for manual and manual versus computer readings, overall results of all manual and computer analyses showed good agreement (ICC = 0.73). Diff-Quik staining is reliable for both manual (liquefied) and computer (washed) analysis of strict sperm morphology. Intra- and inter-computer analyses using this method reached satisfactory levels of agreement. There is still high inter-laboratory variability for the manual method.

Abstract
Progression to the blastocyst stage of embryos derived from testicular round spermatids in men with non-obstructive azoospermia was studied. A total of 56 men were studied in whom partial spermatogenesis failure had occurred where only very few spermatozoa (fewer than the number of oocytes retrieved) were extracted from multiple testicular biopsy specimens. Oocytes remaining after intracytoplasmic injection of testicular spermatozoa (group 1) were injected with round spermatids (ROSI, group 2). Only embryos derived from group 1 were transferred. Remaining embryos were observed under culture for 8 days and their progression to the blastocyst stage was recorded. Of the 546 oocytes injected with testicular spermatozoa, 404 (73.9%) showed evidence of 2-pronuclear (2PN) fertilization. Injection of testicular round spermatids resulted in 2PN fertilization rate of 50% (P < 0.05). Using a four-point grading system, 53% of the good quality embryos (grade 1 or 2) in group 1 reached the blastocyst stage compared with 25% in group 2 (P < 0.05). The rate of progression to the blastocyst stage of grade 3 and grade 4 embryos was 46 and 8.5% in the two groups respectively (P < 0.05). Using a different three-point grading system for the blastocysts, 75.3% of the blastocysts in group 1 were either grade 1 or grade 2 and 24.7% were grade 3. However, in group 2 all blastocysts were grade 3. All embryos observed in group 1 reached the blastocyst stage by day 5 or 6 compared with 25% of the embryos reaching the blastocyst stage by this time in group 2. While 31.2% of the blastocysts in group 1 showed evidence of spontaneous hatching in vitro, none of the blastocysts in group 2 hatched. In conclusion, progression to the blastocyst stage occurred at a much lower and slower rate in embryos derived from testicular round spermatids. Furthermore, all blastocysts resulting from ROSI were of poor quality and none showed spontaneous hatching. These results may explain the dismal outcome associated with ROSI.

OBJECTIVE To investigate the effect of donor's age and her prior fertility on recipient pregnancy outcome in our donor egg program. DESIGN Retrospective cohort analysis. SETTING Large academic infertility center. PATIENT(S) A total of 568 fresh ETs were analyzed for the effect of the egg donor's age on pregnancy outcome; a subset of these (n = 185) were analyzed for the effect of the egg donor's prior fertility on pregnancy outcome. INTERVENTION(S) Donors were paired with recipients independent of recipient's age and donor's prior fertility status. MAIN OUTCOME MEASURE(S) Recipient clinical pregnancy rates (PRs) and delivery rates for different donor age groups and for nulligravid donors versus donors with proven fertility. RESULT(S) Donors > or = 33 years old were less likely than younger donors to produce clinical pregnancies and deliveries in their recipients (43.5% versus 26.6% and 35.1% versus 22.1%, respectively). However, there was no difference in clinical PRs or delivery rates between nulligravid donors and donors with proven fertility. CONCLUSION(S) Donors > or = 33 years of age could be excluded from egg donation because of the lower pregnancy potential of their eggs. However, lack of proven fertility in a donor seems to have no negative impact on pregnancy potential.

Abstract
OBJECTIVES Paraneoplastic arthritis (PA) may mimic rheumatic diseases. While presenting the demographic and laboratory features of the patients diagnosed with PA, this study also aims to provide possible appropriate tools to differentiate the PA cases from early rheumatoid arthritis (ERA). METHODS Sixty-five patients with PA (male/female: 43/22) from 15 different rheumatology clinics and 50 consecutive patients with ERA (male/female: 13/37) fulfilling the 2010 American College of Rheumatology (ACR) criteria for the diagnosis if the RA from Gaziantep Rheumatology Early Arthritis Trial (GREAT) as controls who were diagnosed at least 12 months before, were enrolled into study. RESULTS Mean ages of the patients with PA and ERA were 50.2 ± 15.3, and 42.7 ± 12.3, respectively, and the mean ages of the patients with PA were significantly higher than the ERA. Unlike the ERA patients, in our case series PA was predominantly observed among males. Oligoarthritis was significantly higher in solid tumors in contrast to ERA (P = 0.001). Polyarthritis and symmetric arthritis were significantly higher in the ERA group in contrast to all malignancies (P = 0.001). Rheumatoid factor (RF) and anticyclic citrullinated peptide antibody (anti-CCP) positivity were significantly higher in the ERA group (each P = 0.001). Lactic dehydrogenase levels of hematologic malignancies were significantly higher than other groups (each, P = 0.001). CONCLUSIONS ERA patients had more symmetric joint involvement than PA; laboratory markers could be also an alternative where there is high RF and anti-CCP positivity with antibody levels among the ERA patients. Finally, the demographic features can be used as differentiating factors; ERA was seen predominantly among females aged 40-59 years which refers to young adults.

Abstract
The aim of this study was to compare the efficacy of pure follicle stimulating hormone (FSH) with that of FSH/human menopausal gonadotrophin (HMG) combination in downregulated cycles. A total of 357 patients was evaluated retrospectively. Sixty percent of patients in the FSH group and 55% in the FSH/HMG group were new; the others were repeat patients. Ovulation was suppressed with leuprolide acetate in all patients, followed by either FSH (n = 218) or FSH/HMG (n = 119). There was no difference in patients' age, infertility factors, number of ampoules used, length of stimulation, oestradiol levels on day of human chorionic gonadotrophin (HCG) administration, number of oocytes recovered or the number of embryos transferred. Also, nuclear maturity at aspiration and fertilization rates were not different between the two groups. FSH stimulation resulted in a significantly higher percentage of mature oocytes that showed the typical 'mature' morphological characteristics (P < 0.0001). The clinical pregnancy rates per transfer were 40 and 28% in patients stimulated with pure FSH and FSH/HMG respectively (P < 0.05). The significantly higher number of immature oocytes matured in vitro in the FSH/HMG group (P = 0.001) suggests a possible effect on in-vitro maturation, due to luteinizing hormone present in HMG. The difference in mature oocyte quality may be an important determinant in the higher pregnancy rates for the FSH-stimulated patients.

Abstract
The objective of this study was to investigate the impact of severe oligoasthenoteratozoospermia (OAT) on pregnancy outcome. For this purpose 279 consecutive intracytoplasmic sperm injection (i.c.s.i) cycles were retrospectively evaluated and compared to 436 consecutive IVF cycles performed during the same time frame. Group A (n = 62) included ICSI patients with severe OAT; group B (n = 217) included patients who underwent ICSI for other indications; and group C (n = 436) included couples who underwent standard IVF. The mean age of female patients and mean number of embryos transferred were comparable in all groups. No difference was observed regarding implantation, clinical pregnancy, delivery and miscarriage rates between all three groups, but fertilization rate was significantly lower in group A than in groups B and C. It is concluded that couples undergoing ICSI with severe male infertility (OAT) have a slightly reduced fertilization rate but their chances of delivery and pregnancy loss are similar to those of other patients undergoing clinical ICSI and IVF with non-male infertility.

Abstract
AIM Cognitive dysfunction is a neurologic manifestation in primary Sjögren syndrome (PSS). On the other hand, several antibodies are related to cognitive dysfunction. The aim of this study is to assess the cognitive dysfunction of PSS patients via detailed neurologic tests. Moreover, its associations with antibodies were also evaluated. METHOD Twenty-eight female patients with PSS and 17 healthy controls comprised the study groups. Short-term memory, long-term memory, verbal learning, visual memory, visual spatial perception, attention, verbal frequency function, executive functions and information processing speed were evaluated with neurologic tests in both of the study groups. Furthermore, anti-N-methyl-D-aspartate (NMDA) type anti-glutamate-receptor antibody, anti-ribosomal-p and antiganglioside antibodies were assessed in the study groups. RESULTS The attention, data processing speed, verbal learning, short-term verbal memory and visuo-spatial perception performances were lower in the patients with PSS when compared to the healthy controls. The difference reached statistical significance in Paced Auditory Serial Addition Test (P < 0.01), Serial Digit Learning Test (P < 0.01), clock drawing (P = 0.03), Auditory Verbal Learning Test immediate verbal memory (P = 0.01) and Benton Judgement of Line Orientation Test (P = 0.03). Even if antiganglioside antibodies were more likely to be present in the PSS group when compared to the healthy controls, no relationship was found between its positivity and cognitive dysfunction. CONCLUSION Results of this study suggest that cognitive dysfunction is quite prevalent in PSS patients without being associated with studied antibodies.

Abstract
OBJECTIVE Some case reports indicated that red cell status increased after hepatitis C viral infection. The aim of study was to define the influence of hepatitis C infection (HCV) on red cell status in hemodialyzed patients. MATERIALS AND METHODS A total of 49 (21 anti-HCV-positive and 28 anti-HCV-negative) patients with ESRD were included in this study. Exclusion criteria were blood transfusion and massive blood loss in the last 6 months preceding the study. None of the patients used any drug containing aluminum. RESULTS The prevalence of anti-HCV antibody was 42.8%. Mean age was 51.6 +/- 14.3 in anti-HCV (+) group and 50.4 +/- 17.0 in anti-HCV (-) group. There was no statistically significant difference between the ages of the 2 groups. Mean duration time of hemodialysis was significantly longer in patients with anti-HCV antibody (+) group (54.9 +/- 34.2 months) compared to anti-HCV-negative group (12.5 +/- 9.0 months) (p < 0.001). Mean hemoglobin (Hb) and hematocrit (Htc) levels were significantly higher in anti-HCV-positive patients than in anti-HCV-negative patients (Hb: 10.4 +/- 1.8 g/dl, Htc: 30.5 +/- 5.5% vs Hb: 8.8 +/- 1.7 g/dl, Htc: 26.1 +/- 5.3%) (for Hb p < 0.005, for Htc p < 0.007). There was no significant difference regarding the usage ofrHuEPO between the 2 study groups (57.1% in anti-HCV antibody (+)/59.3% in anti-HCV antibody (-)) (p > 0.05). All patients not receiving rHuEPO did so because of economical reasons. Serum AST and ALT levels were significantly higher in the anti-HCV antibody-positive group compared with the anti-HCV antibody-negative group. (AST p < 0.04, ALT p < 0.04). CONCLUSION Anti-HCV antibody-positive ESRD patients have higher hemoglobin and hematocrit levels compared to HCV-negative patients.

Abstract
PURPOSE The objectives of this study were (1) to investigate intracytoplasmic sperm injection (ICSI) outcome according to its indications, i.e., a history of failed or poor fertilization and unsuitable sperm parameters for conventional IVF, and (2) to examine the impact of a female's age, sperm concentration, motility, morphology, presence of antisperm antibodies, and hemizona assay (HZA) results on overall outcome. METHODS Two hundred seventy-nine ICSI cycles performed in 207 couples were retrospectively evaluated. RESULTS Clinical pregnancy and delivery rates were 36.8 and 29.8% for patients with prior failed fertilization, 23.2 and 17.8% for patients who had prior poor fertilization, and 28.6 and 21.3% for patients with unsuitable sperm parameters. The differences among all groups were found to be insignificant. There was a significant, negative correlation between a female's age and pregnancy results. No difference was found in the three basic sperm parameters between those patients who produced and those who did not produce a pregnancy, but the fertilization rate was significantly higher in patients with more adequate sperm parameters. Although there was a trend toward a better fertilization rate in patients with a hemizona index (HZI) greater than 30 (indicative of a superior sperm-zona pellucida binding capacity) than in those with a HZI less than 30, the difference was not significant. There were no differences in fertilization rate according to the presence or absence of antisperm antibodies. CONCLUSIONS Fertilization history in a conventional IVF cycle has no effect on success rates following ICSI, and there is no correlation among the basic sperm parameters, the presence of antisperm antibodies, and pregnancy rates.

Abstract
A prospective study was performed to determine the feasibility of evaluating the uterine cavity by sonohysterography (SHG) in women who were scheduled for intracytoplasmic sperm injection (ICSI) due to severe male factor infertility and who had not had a previous hysterosalpingography (HSG). Sonohysterography was performed in 80 women scheduled for ICSI. A subsequent hysteroscopy was undertaken in patients with intracavitary lesions. The outcome of ICSI for the women undergoing SHG was compared with that of 240 cycles performed (during the same time period) in patients who had a normal HSG before admission to the clinic. There were no complications attributable to the SHG procedure. Hysteroscopy correctly identified all lesions depicted by SHG. SHG and HSG groups were comparable with regard to female age and duration of infertility. Clinical pregnancy rates per transfer were 40.2% and 42.5% in the SHG and HSG groups, respectively. Abortion rates in the two groups were also similar (14.8 and 11.0%, respectively). In conclusion, sonohysterography appears to be a simple, inexpensive, and safe alternative to HSG for evaluation of the uterine cavity in women scheduled for ICSI.
