Abstract:Objectives: For women who suffer from systemic lupus erythematosus (SLE), pregnancy can be a concern, placing the mother and fetus at risk. Our objectives were to assess the risk of adverse pregnancy outcome, disease flares, fertility rate, and co-morbidities in SLE women compared to healthy controls. We also systematically reviewed the literature available on pregnancy outcome in SLE to compare our results to other published data. Our hypothesis was that pregnancy outcome in SLE is improving over time.Methods: A case-control study comparing self-report of the above-mentioned parameters in SLE (N=108) vs healthy controls or patients with non-inflammatory musculoskeletal (MSK) disorders (N=134) was performed. Data were collected using a self-administered questionnaire. Proportions, means and odds ratios were calculated. We searched and quantified the literature on pregnancy outcome, lupus reactivation and fertility rate. Data were summarized and presented in mean % ± SEM and median % with interquartile range (IQR).Results: Gynecological history, fertility rate and age at first pregnancy in SLE patients were comparable to controls. Eighteen percent of SLE patients reported a flare and 18% reported an improvement of symptoms during pregnancy. Twenty-four percent of lupus patients had at least one preterm delivery vs 5% in controls (OR =8.32, p = 0.0008), however other pregnancy outcomes (miscarriage, therapeutic abortion, stillbirth and neonatal death rate) did not differ between the groups. Thyroid problems were reported to be more likely in SLE patients (p = 0.02), but the prevalence of other co-morbidities was similar to controls. A literature review demonstrated that fertility was not affected in SLE patients. Lupus reactivations are common during pregnancy (36.5% ± SEM 3.3%). Most agreed that SLE pregnancies had more fetal loss (19.5% ± SEM 1.6%) and preterm births (25.5% ± SEM 2.2%) when compared to the general population. Over time, the rate of SLE peripartum flares has improved (p = 0.002) and the proportion of pregnancies resulting in live birth has increased (p = 0.024). The frequency of fetal death has not significantly changed. Our findings from the casecontrol study were, in general, consistent with the literature including the frequency of fetal death, neonatal death, live births and pregnancy rate.Conclusion: Prematurity (25.5% ± SEM 2.2%) and fetal death (19.5% ± SEM 1.6%) in SLE pregnancy are still a concern. However, new strategies with respect to pregnancy timing and multidisciplinary care have improved maternal and fetal outcome in SLE.

Objective-To review the literature on the epidemiology of Campylobacter associated ReA.

Total laparoscopic hysterectomy (LH) is a minimally invasive technique, which results in comparable morbidity and better cosmesis compared with total abdominal hysterectomy. The literature is discrepant as to whether it is associated with a higher incidence of positive peritoneal cytology compared with total abdominal hysterectomy and recently, associated artifacts, including vascular pseudoinvasion (VPI), have been described. A retrospective histopathologic review of 266 hysterectomy specimens from 2 centers was performed. The observers, blinded to the surgical technique, assessed for the presence of artifactual changes including disruption of the endometrial lining, nuclear crush artifact, VPI, endomyometrial cleft artifact with or without epithelial displacement, inflammatory debris within vessels, serosal carryover, and intratubal contaminants. In addition, the rates of positive peritoneal washings over a 5-year period, and the use of immunohistochemistry (IHC) to aid in cell typing over a 3-year period, were compared between hysterectomies in which a uterine manipulator (UM) device had and had not (nonmanipulated hysterectomies) been used. The hysterectomies were performed for malignant (n=160) and benign (n=102) uterine disease or for ovarian or cervical disease (n=4), and included total abdominal (n=108), vaginal (n=17), laparoscopy-assisted vaginal (n=24), laparoscopy converted to laparotomy (n=10), nonrobotic laparoscopic (n=51), and robot-assisted laparoscopic (n=56) hysterectomies. One hundred and two (38%) of these hysterectomies involved the use of a UM. Artifactual changes of disruption of the endometrial lining, endomyometrial clefts, intratubal contaminants, nuclear crush artifact, intravascular inflammatory debris, and VPI were significantly more common with LH and with the use of a UM, independent of whether the endometrial pathology was benign or malignant. IHC to aid in endometrial cancer subtyping was more likely to be used in manipulated hysterectomies (P=0.0166). Furthermore, peritoneal washings were significantly more likely to be positive in hysterectomies in which a UM had been used (P=0.0061). Histologic artifacts are significantly more common in LH and specifically in hysterectomies in which a UM is used. Such artifacts impair the pathologists' interpretation of cell type requiring an increased use of IHC, and displaced epithelial fragments present within vessels or artifactual clefts may result in the misinterpretation of prognostic and staging parameters. Furthermore, there is a significantly higher rate of positive peritoneal cytology in cases that are subjected to uterine manipulation, suggesting dissemination of malignant cells into the abdominal cavity. The clinical significance of this finding needs to be determined.
