The concentrations of endometrial proteins PP14 and CA-125 were measured in uterine flushings taken on days LH+10 and LH+12 (10 and 12 days after luteinizing hormone surge) of the menstrual cycle from 15 normal, fertile women and 49 women who suffered recurrent miscarriage. The concentration of PP14 was significantly lower in the flushings from the recurrent miscarriage patients than in those from fertile controls on both day LH+10 (median: 1300, range: 3-10 300 ng/ml versus median: 13 933, range: 2174-40 404 ng/ml; P < 0.01) and LH+12 (median: 1560, range: 820-12 100 ng/ml versus median: 14 047, range 1402-62 108 ng/ml; P < 0.05). Similarly concentrations of CA-125 were significantly lower in flushings from recurrent miscarriage women compared to controls on both day LH + 10 (median: 1555, range: 47-6710 U/ml versus median: 6385.5, range 2884-27 731 U/ml, P < 0.01) and LH+12 (median: 2892, range: 956-9974 U/ml versus median: 7127.5, range: 1591-21 343 U/ml; P < 0.05). In contrast there was no significant difference in the concentration of PP14 in plasma samples taken on the same days as the flushings from recurrent miscarriage patients and fertile controls. The concentrations of PP14 in uterine flushings obtained on day LH + 10 or LH + 12 from recurrent miscarriage women during a pre-pregnancy investigative cycle were significantly lower (P < 0.05) in patients who went on to miscarry (median: 1000, range: 9-2900 ng/ml) than those who went on to have a live birth (median: 1440, range: 4-12 100 ng/ml) during a subsequent pregnancy. In contrast there was no significant difference in uterine CA-125 or plasma PP14 concentrations between these two groups of recurrent miscarriage patients. The results suggest that measurements of uterine PP14 and CA-125 may be useful in the assessment of endometrial development in recurrent miscarriage patients and suggest the importance of PP14 in preparing the endometrium for embryo implantation. In addition pre-pregnancy uterine PP14

Recurrent pregnancy loss (RPL) occurs in ∼5% of women. However, the etiology is still poorly understood. Defects in decidualization of the endometrium during early pregnancy contribute to several pregnancy complications, such as pre-eclampsia and intrauterine growth restriction (IUGR), and are believed to be important in the pathogenesis of idiopathic RPL. We performed microarray analysis to identify gene expression alterations in the deciduas of idiopathic RPL patients. Control patients had one antecedent term delivery, but were undergoing dilation and curettage for current aneuploid miscarriage. Gene expression differences were evaluated using both pathway and gene ontology (GO) analysis. Selected genes were validated using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). A total of 155 genes were found to be significantly dysregulated in the deciduas of RPL patients (>2-fold change, P < 0.05), with 22 genes up-regulated and 133 genes down-regulated. GO analysis linked a large percentage of genes to discrete biological functions, including immune response (23%), cell signaling (18%) and cell invasion (17.1%), and pathway analysis revealed consistent changes in both the interleukin 1 (IL-1) and IL-8 pathways. All genes in the IL-8 pathway were up-regulated while genes in the IL-1 pathway were down-regulated. Although both pathways can promote inflammation, IL-1 pathway activity is important for normal implantation. Additionally, genes known to be critical for degradation of the extracellular matrix, including matrix metalloproteinase 26 and serine peptidase inhibitor Kazal-type 1, were also highly up-regulated. In this first microarray approach to decidual gene expression in RPL patients, our data suggest that dysregulation of genes associated with cell invasion and immunity may contribute significantly to idiopathic recurrent miscarriage.

Background: Antinuclear antibodies (ANAs) in women with recurrent miscarriage have been reported. The presence of moderate to high titers of these antibodies represents an autoimmune condition that can endanger the health of the fetus in pregnant women. Objective: In this study, we evaluated the prevalence of ANAs in Iranian women with a history of two or more unexplained abortion. Materials and Methods: 560 women with unexplained recurrent miscarriage and 560 healthy controls accounted for this study over a period of 13 months. ANAs were detected by indirect immunofluorescence technique. Results: ANAs were detected in 74 of 560 (13.21%) patient with recurrent miscarriage, and in only 5 of 560 (0.9%) controls (p<0.001). ANA positivity was generally found with low-positive results (1.40-1.80) in about 38% of positive cases, whereas moderate titres (1.160-1.320) and high titres (>1.640) were seen in about 46% and 16% of cases respectively. Finally evaluating of microscopic ANA patterns revealed that about half of positive cases had antibodies against DNA- histone complex, associated with systemic lupus erythematosus disease. Conclusion: Antinuclear antibodies are not uncommon in women with unexplained recurrent miscarriage, suggesting the possible role of an autoimmune disorder on abortion, at least in a subgroup of patients.

To evaluate the predictive value of three-dimensional (3D)-power Doppler sonography on recurrent miscarriage. The study patients were divided into a recurrent miscarriage group (30 cases) and a normal pregnancy group (21 cases). Measurement of endometrial thickness was performed using two-dimensional transvaginal ultrasound in the midluteal phase. The endometrial volume, vascularization index (VI), flow index (FI), and vascularization-flow index (VFI) in midluteal and placenta volume, as well as the VI, FI, and VFI of early pregnancy were measured using Virtual Organ Computer-aided Analysis of 3D-power Doppler ultrasound. Endometrial thickness, endometrial volume, endometrial vascular data, VI, FI, and VFI of the midluteal phase were lower in the recurrent miscarriage group compared with the normal pregnancy group (p < 0.05). Placental volume, VI, and VFI during early pregnancy were lower in the miscarriage group compared with the normal pregnancy group (p < 0.05). There was no significant change in FI between the recurrent miscarriage and control groups during early pregnancy (p > 0.05). The predictive accuracy of endometrial thickness, endometrial volume, VI, FI, and VFI in the midluteal phase, and placenta volume, VI, FI, and VFI in early pregnancy as measured by the receiver operating characteristic curve to predict miscarriage before 12 gestational weeks in participants was 0.681, 0.876, 0.770, 0.720, 0.879, 0.771, 0.907, 0.592, respectively. The 3D-power Doppler ultrasound is a more comprehensive and sensitive method for evaluating endometrial receptivity. Endometrial volume, VI, FI, and VFI in the midluteal phase, as well as VI in early pregnancy, can be considered as predictive factors for recurrent miscarriage. Copyright © 2015.

Recurrent miscarriage (RM) affects 5% of women, it has an adverse emotional impact on women. Because of the complexities of early development, the mechanism of recurrent miscarriage is still unclear. We hypothesized that abnormal placenta leads to early recurrent miscarriage (ERM). The aim of this study was to identify ERM associated factors in human placenta villous tissue using proteomics. Investigation of these differences in protein expression in parallel profiling is essential to understand the comprehensive pathophysiological mechanism underlying recurrent miscarriage (RM). To gain more insight into mechanisms of recurrent miscarriage (RM), a comparative proteome profile of the human placenta villous tissue in normal and RM pregnancies was analyzed using iTRAQ technology and bioinformatics analysis used by Ingenuity Pathway Analysis (IPA) software. In this study, we employed an iTRAQ based proteomics analysis of four placental villous tissues from patients with early recurrent miscarriage (ERM) and four from normal pregnant women. Finally, we identified 2805 proteins and 79,998 peptides between patients with RM and normal matched group. Further analysis identified 314 differentially expressed proteins in placental villous tissue (≥1.3-fold, Student's t-test, p < 0.05); 209 proteins showed the increased expression while 105 proteins showed decreased expression. These 314 proteins were analyzed by Ingenuity Pathway Analysis (IPA) and were found to play important roles in the growth of embryo. Furthermore, network analysis show that Angiotensinogen (AGT), MAPK14 and Prothrombin (F2) are core factors in early embryonic development. We used another 8 independent samples (4 cases and 4 controls) to cross validation of the proteomic data. This study has identified several proteins that are associated with early development, these results may supply new insight into mechanisms behind recurrent miscarriage.

The aim of this study was to investigate the possible association between recurrent miscarriage (RM) and ectopic pregnancy (EP). In this case-control retrospective study, the clinical cards of women followed as outpatients in the RM and low-risk pregnancy offices of the Obstetrics and Gynecology Unit at the Policlinico Tor Vergata University Hospital were carefully reviewed for the occurrence of EP. Overall, 598 women with RM and 2043 normal women without RM (controls) were included in the study. Among these women, 4974 pregnancies were analyzed, in which 2028 miscarriages occurred. The EP rate (3.51%) was significantly higher in RM than in control women (1.51%) [odds ratio = 2.31 (95% confidence interval: 2.3-2.4)]; it was particularly high in women with primary RM (5.11%). However, when EP rates were calculated not by women but by overall pregnancies, no differences could be found between RM and control women. In control women, the absence of a miscarriage in the reproductive history was associated with a lower rate of EP. Women with RM, particularly primary RM, are at increased risk of EP. This increased risk seems to be dependent on the high number of pregnancies occurring in women with RM rather than to specific characteristics of these women. © 2018 Japan Society of Obstetrics and Gynecology.

Chinese herbal medicine for the treatment of recurrent miscarriage: a systematic review of randomized clinical trials

PubMed Central

2013-01-01

Background Traditional Chinese medicine has been widely used for the treatment of recurrent miscarriage in China and other Asian countries for long time. We conducted this review to systematically summarize the evidences of Chinese herbal medicine (CHM) for the prevention and treatment of recurrent miscarriage in randomized trials, and evaluate the effectiveness and safety of CHM compared with placebo or conventional medicine. Methods We searched studies in PubMed, ClinicalTrials, the Cochrane Library, CNKI, SinoMed and VIP databases until December, 2012. Randomized trials on CHM alone or in combination with conventional medicine for recurrent miscarriage compared with placebo or conventional medicine were included. We evaluated the methodological quality of each included trials using the Cochrane risk of bias tool. Results A total of 41 RCTs (3660 participants) were included. The majority of trials had a high or unclear risk of bias. CHM used alone or plus progesterone-based treatment showed superior effect over progesterone-based treatment in improving live birth rate and embryonic developmental state (measured by B ultrasound). However, there is substantial heterogeneity within each subgroup analysis (I2 ranging from 35% to 71%). CHM plus progesterone and hCG-based treatment was superior to progesterone and hCG-based treatment in improving the embryonic developmental state, but not live birth rate. No severe adverse events were reported in relation to CHM. Conclusions Some Chinese herbal medicines or in combination with progesterone-based treatment demonstrated potentially beneficial effect in improving live birth rate and embryonic developmental state for women with recurrent miscarriage. However, due to the substantial heterogeneity among the herbal interventions and limitations of methodological quality of the included trials, it is not possible to recommend any specific CHMs for recurrent miscarriage. Further rigorous clinical trials are warranted to

To determine whether the frequency of euploid miscarriage is increased in obese women with recurrent early pregnancy loss (REPL). Observational cohort study using prospectively collected data. Academic RPL program. A total of 372 women with REPL, defined as ≥2 pregnancy losses<10 weeks, and at least one ultrasound-documented miscarriage with chromosome results. Body mass index (BMI) was measured at the initial consultation and at each subsequent pregnancy. Conventional cytogenetic analysis and, when indicated, microsatellite analysis and/or comparative genomic hybridization was performed. Frequency of euploid miscarriage in obese (BMI≥30 kg/m2) and nonobese (BMI<30 kg/m2) subjects, before and subsequent to REPL evaluation. There were 578 miscarriages with chromosome results. Of the subjects, 18% were obese at the time of miscarriage. The mean maternal age at miscarriage was similar between the obese and nonobese groups. Due to the high rate of maternal cell contamination in the prior miscarriages, only subsequent miscarriages with chromosome results were included in the primary analysis. Of the 117 subsequent miscarriages, the frequency of an euploid miscarriage among obese women was 58% compared with 37% of nonobese women (relative risk=1.63; 95% confidence interval 1.08-2.47). Obese women with REPL have an increased frequency of euploid miscarriage, which is a known risk factor for subsequent miscarriage. Copyright © 2014 American Society for Reproductive Medicine.

To investigate whether antinuclear autoantibodies (ANA) could be related to the outcome of the successive pregnancy in women with unexplained recurrent miscarriage (uRM). Circulating ANA were measured by indirect immunofluorescence in 86 women with uRM before pregnancy, repeated in the first trimester of the successive gestation and correlated with pregnancy outcome. Forty-one women were ANA- and 45 were ANA+ before pregnancy. No relation was found between pre-pregnancy ANA status and the outcome of the successive pregnancy. However, when these women were monitored at 7th week during their pregnancy for ANA, of the 22 ANA+ women who remained ANA+ seven miscarriages (31.8%) were observed, whereas all of the 23 ANA+ women who became ANA- had pregnancies ongoing beyond the 20th week without miscarriage. ANA status could have a role in uRM. Disappearance of ANA in early pregnancy could have a favorable prognostic value in the successive pregnancy. © 2016 John Wiley & Sons A/S.

Medical treatment of women with idiopathic recurrent pregnancy loss is controversial. The objective was to assess the effects of different treatments on live birth rates and complications in women with unexplained recurrent pregnancy loss. We searched MEDLINE, Embase and the Cochrane Library, and identified 1415 publications. This systematic review included 21 randomized controlled trials regarding acetylsalicylic acid, low-molecular-weight heparin, progesterone, intravenous immunoglobulin or leukocyte immune therapy in women with three or more consecutive miscarriages of unknown cause. The study quality was assessed and data was extracted independently by at least two authors. No significant difference in live birth rate was found when acetylsalicylic acid was compared with low-molecular-weight heparin or with placebo. Meta-analyses of low-molecular-weight heparin vs. control found no significant differences in live birth rate [risk ratio (RR) 1.47, 95% CI 0.83-2.61]. Treatment with progesterone starting in the luteal phase seemed effective in increasing live birth rate (RR 1.18, 95% CI 1.09-1.27) but not when started after conception. Intravenous immunoglobulin showed no effect on live birth rate compared with placebo (RR 1.07, 95% CI 0.91-1.26). Paternal immunization compared with autologous immunization showed a significant difference in outcome (RR 1.8, 95% CI 1.34-2.41), although the studies were small and at high risk of bias. The literature does not allow advice on any specific treatment for idiopathic recurrent pregnancy loss, with the exception of progesterone starting from ovulation. We suggest that any treatment for recurrent pregnancy loss should be used within the context of a randomized controlled trial. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

Thyroid disorders have been associated with recurrent miscarriage. Little evidence is available on the influence of subclinical hypothyroidism on live birth rates. In this cohort study, women who had experienced miscarriage and subclinical hypothyroidism (defined as thyroid-stimulating hormone >97.5th percentile mU/l with a normal thyroxine level) were investigated; the control group included women who had experienced recurrent miscarriage and normal thyroid function. Multivariable logistic regression was used to investigate the association of subclinical hypothyroidism. Data were available for 848 women; 20 (2.4%) had subclinical hypothyroidism; 818 women (96%) had euthyroidism; and 10 (1.2%) had overt hypothyroidism. The live birth rate was 45% in women with subclinical hypothyroidism and 52% in euthyroid women (OR 0.69, 95% CI 0.28 to 1.71). The ongoing pregnancy rate was 65% versus 69% (OR 0.82, 95% CI 0.32 to 2.10) and the miscarriage rate was 35% versus 28% (OR 1.43, 95% CI 0.56 to 3.68), respectively. No differences were found when thyroid stimulating hormone 2.5 mU/l was used as cut-off level to define subclinical hypothyroidism. In women with unexplained miscarriage, no differences were found in live birth, ongoing pregnancy and miscarriage rates between women with subclinical hypothyroidism and euthyroid women.

A total of 500 consecutive women (mean age 32.9 years; SD 5 years) presenting with a history of recurrent miscarriages (median 4; range 3-17) were investigated for the presence of antiphospholipid antibodies (APA), polycystic ovaries (PCO), hypersecretion of luteinizing hormone (LH) and chromosome abnormalities in order to detect an underlying cause of their pregnancy losses. All women had details of their previous reproductive history, investigations and treatment documented: 76% of the women had experienced only early pregnancy losses (miscarriage < 13 weeks gestation); 32% had a history of subfertility; and significant parental chromosome rearrangements were present in 3.6% of couples. An ultrasound diagnosis of PCO was made in 56% of women, 58% of whom were demonstrated to hypersecrete LH, based on early morning urinary LH analysis. Circulating APA were found in 14% of women. An underlying cause of recurrent miscarriage--genetic, endocrine or autoimmune--was found in > 50% of couples. Women in the latter two groups are being recruited to randomized treatment trials which are discussed.

Antiphospholipid and antioangiogenic activity in females with recurrent miscarriage and antiphospholipid syndrome.

Background Antiphospholipid syndrome is an autoimmune disease characterized by thrombosis, fetal losses and thrombocytopenia associated to antiphospholipid antibodies. They are directed to phospholipids, such as cardiolipins (anticardiolipin) and lupus anticoagulant or to complexes formed by phospholipids and protein cofactors, such as β2 glycoprotein 1 (a-β2GP1) and annexin V (a-annexin V). These auto-antibodies may be considered as a family of antibodies involved in thrombotic events and antiphospholipid activity. On the other hand, some proangiogenic factors are involved in the normal development of placental vasculature, such as the vascular endothelial growth factor. Overexpression of vascular endothelial growth factor receptor in its soluble form (sVEGFR-1) has been associated to a higher antiangiogenic activity. Our aim was to analyse the association between anticardiolipin, lupus anticoagulant, a-β2GP1, a-annexin V and sVEGFR-1 with recurrent miscarriage before week 10 of gestation in females with antiphospholipid syndrome. Methods We studied 24 females (primary or secondary antiphospholipid syndrome), who were divided into two groups: females with recurrent miscarriage before week 10 of gestation (M; n = 12) and females with no history of fetal loss (NM; n = 12). Anticardiolipin, a-β2GP1, a-annexin V and sVEGF-R1 concentrations were assessed by ELISA, while lupus anticoagulant was assessed by screening and confirmatory tests. Results A significant association was observed between the number of positive biomarkers and the belonging group ( P < 0.05). Besides, a positive result for lupus anticoagulant and a-β2GP1 was found to be significantly associated to the M group ( P < 0.05). Conclusions Lupus anticoagulant and a-β2GP1 may be implicated in pregnancies complicated by recurrent miscarriage in females with antiphospholipid syndrome.

Objective. Women with infertility and recurrent miscarriages may have an overlapping etiology. The aim of this study was to compare the pregnancy loss in pregnancies after IVF treatment with spontaneous pregnancies in women with recurrent miscarriages and to assess differences related to cause of infertility. Methods. The outcome from 1220 IVF pregnancies (Group I) was compared with 611 spontaneous pregnancies (Group II) in women with recurrent miscarriages. Subgroup analysis was performed in Group I based on cause of infertility: tubal factor (392 pregnancies); male factor (610 pregnancies); and unexplained infertility (218 pregnancies). Results. The clinical pregnancy loss rate in Group I (14.3%) was significantly lower than that of Group II (25.8%, p < 0.001) and this was independent of the cause of infertility. However the timing of pregnancy loss was similar between Groups I and II. The clinical pregnancy loss rate in Group I was similar in different causes of infertility. Conclusions. The clinical pregnancy loss rate following IVF treatment is lower than that of women with unexplained recurrent miscarriages who conceived spontaneously. This difference persists whether the infertility is secondary to tubal factors, male factors, or unexplained cause. PMID:26576157

Oral anticoagulant therapy for more than 6 months in patients with an episode of idiopathic thromboembolic disease is controversial. The objective was to determine predictive clinical signs that identify patients at increased risk of thromboembolic recurrence after stopping anticoagulant therapy for 6 months after an episode of idiopathic deep vein thrombosis (DVT). A prospective study which included 306 consecutive patients with a first episode of idiopathic DVT from June 2012 to June 2014. Predictor variables of recurrent thromboembolic disease and episodes of recurrence during follow-up of the patients (28.42 months) were collected. We performed a multivariate analysis to analyze possible predictors (P<.20) and an analysis of Kaplan-Meier to establish mean recurrence-free survival. We identified 91 episodes of residual vein thrombosis on follow-up of the patients (37.5% men and 20.3% women) (OR 1.84; 95% CI 1.25-2.71). In the Cox regression analysis stratified by gender, variables showed significant presence of hyperechoic thrombus (P=.001) in males, and persistence of residual thrombus in women (P=.046). The mean recurrence-free survival was shorter in both groups. The presence of echogenic thrombus in men and the existence of residual DVT in women were 2 clinical signs associated with increased risk of thromboembolic recurrence after stopping anticoagulant therapy for 6 months after an episode of idiopathic DVT in our study.

Primary hyperparathyroidism (pHPT) in pregnancy is reported to be associated with significant maternal and foetal complications and an up to threefold increase in the risk of miscarriage. However, the true incidence of pHPT in pregnancy, complete and miscarried, is unknown and there are no data on the prevalence of undiagnosed pHPT in recurrent miscarriage (RM) (≥3 consecutive miscarriages under 24-week gestation). This is the first prospective study aiming to establish the prevalence of undiagnosed pHPT in RM. Following UK National ethics committee approval, women who had experienced 3 or more consecutive miscarriages were recruited from a nationwide RM clinic. Serum corrected calcium, phosphate, PTH and vitamin D were evaluated. Patients with raised serum calcium and/or PTH were recalled for confirmatory tests. Power calculations suggested that a minimum of 272 patients were required to demonstrate a clinically significant incidence of pHPT. Three hundred women were recruited, median age 35 years (range 19-42). Eleven patients had incomplete data, leaving 289 patients suitable for analysis; 50/289 patients (17%) with abnormal tests were recalled. The prevalence of vitamin D deficiency (<25 nmol/l) and insufficiency (25-75 nmol/l) was 8.7 and 67.8%, respectively. One patient was diagnosed with pHPT (0.34%) and underwent successful parathyroidectomy. The prevalence of undiagnosed pHPT (0.34%) in RM in this study appears to be many times greater than the 0.05% expected in this age group. The findings of this pilot study merit follow-up with a larger-scale study. Routine serum calcium estimation is not currently undertaken in RM and should be considered.

Are non-visualized pregnancy losses (biochemical pregnancy loss and failed pregnancy of unknown location combined) in the reproductive history of women with unexplained recurrent miscarriage (RM) negatively associated with the chance of live birth in a subsequent pregnancy? Non-visualized pregnancy losses contribute negatively to the chance for live birth: each non-visualized pregnancy loss confers a relative risk (RR) for live birth of 0.90 (95% CI 0.83; 0.97), equivalent to the RR conferred by each additional clinical miscarriage. The number of clinical miscarriages prior to referral is an important determinant for live birth in women with RM, whereas the significance of non-visualized pregnancy losses is unknown. A retrospective cohort study comprising 587 women with RM seen in a tertiary RM unit 2000-2010. Data on the outcome of the first pregnancy after referral were analysed for 499 women. The study was conducted in the RM Unit at Rigshospitalet, Copenhagen, Denmark. We included all women with unexplained RM, defined as ≥3 consecutive clinical miscarriages or non-visualized pregnancy losses following spontaneous conception or homologous insemination. The category 'non-visualized pregnancy losses' combines biochemical pregnancy loss (positive hCG, no ultrasound performed) and failed PUL (pregnancy of unknown location, positive hCG, but on ultrasound, no pregnancy location established). Demographics were collected, including BMI, age at first pregnancy after referral and outcome of pregnancies prior to referral. Using our own records and records from other Danish hospitals, we verified the outcome of the first pregnancy after referral. For each non-visualized pregnancy loss and miscarriage in the women's reproductive history, the RR for live birth in the first pregnancy after referral was determined by robust Poisson regression analysis, adjusting for risk factors for negative pregnancy outcome. Non-visualized pregnancy losses constituted 37% of reported

Previous studies suggest that women with asthma are at increased risk of preterm birth. Moreover, drugs (especially beta-agonists) used to treat asthma are also used to treat preterm labor. The authors carried out a case-control study of 555 women from three hospital centers with idiopathic preterm labor (< 37 weeks), including two overlapping (i.e., non-mutually exclusive) subsamples: cases with early idiopathic preterm labor (< 34 weeks) and cases with idiopathic recurrent preterm labor (< 37 weeks plus a previous history of preterm delivery or second-trimester miscarriage). Controls were matched to cases according to race and smoking history prior to and during pregnancy. All subjects responded in person to questions about atopic, respiratory, obstetric, and sociodemographic histories. Subjects in the early and recurrent preterm labor subsamples were also asked to undergo spirometric testing with methacholine challenge 6-12 weeks after delivery. Cases were significantly more likely to report histories of asthma symptoms and physician-diagnosed asthma (matched odds ratios of 2-3) than controls, particularly those cases with recurrent preterm labor. No significant associations were observed, however, with methacholine responsiveness. These results could not be explained by residual confounding by smoking or other variables, nor by selective recall of asthma symptoms and histories by cases. Women with asthma are at increased risk of idiopathic preterm labor. The fact that no such association was seen with methacholine responsiveness suggests that nonatopic, noncholinergic mechanisms may link bronchial and uterine smooth muscle lability.

To assess the perinatal outcomes and risk factors for further pregnancy loss in patients with recurrent miscarriage treated with lymphocyte immunotherapy (LIT). We performed a retrospective observational study of women with a history of two or more consecutive miscarriages who underwent LIT. All patients had undergone investigation of the etiology of the pregnancy losses according to a specific protocol. These etiologic factors were compared between those whose pregnancy outcome was successful and those who had a further miscarriage. The comparison between the groups was performed by Kruskal-Wallis, Fisher exact and Chi-square tests. Perinatal outcome data were collected for the successful pregnancies. One-hundred six patients were included. The mean number (±SD) of previous pregnancies, deliveries and miscarriages in all patients were 2.73 ± 0.8, 0.19 ± 0.4 and 2.54 ± 0.6, respectively. A successful pregnancy outcome after lymphocyte therapy occurred in 82 patients (group I), while 24 (22.6%) sustained a further miscarriage (group II). There was no statistical difference in the genetic, anatomic and hormonal causes of miscarriage between the groups (p > 0.05). Antinuclear (ANA) and antithyroglobulin (TgAb) autoantibodies occurred more frequently in group II (p = 0.0010 and p = 0.0024, respectively). Of those with successful pregnancies, 11 women (13.4%) had a preterm delivery. The mean birth weight was 3036.4 ± 498.6 g. In patients with recurrent miscarriage treated with LIT, the presence of ANA and TgAb was a risk factor for further pregnancy loss. Perinatal outcomes in those whose pregnancies continued were favorable.

The role of ILT4 + DCs in healthy fertile controls and patients with recurrent miscarriages (RM) and recurrent implantation failure (RIF) is unclear. We studied the expression of ILT4 from peripheral blood and endometrial samples from healthy controls and patients with RM and RIF by flow cytometry and immunohistochemistry analysis. Endometrial Foxp3 expression was also investigated using immunohistochemistry. In peripheral blood, there was a significant increase in the percentage of ILT4 + DCs in healthy fertile controls compared with patients with RM and RIF. The presence of ILT4 + DC is even more prominent in the endometrium of healthy fertile controls compared with patients with RM and RIF. Moreover, there was a strong correlation between the number of ILT4 + cells and Foxp3 + Tregs in healthy fertile controls, but not in patients with RM and RIF. Our data indicate that ILT4 + DCs play an important role in the maintenance of immune tolerance during pregnancy, probably through the induction of Foxp3 + Treg cells, a process which is impaired in RM and RIF. © 2018 John Wiley & Sons A/S.

A seven-month-old, neutered male Catahoula leopard dog cross was presented for recurrent urethral obstruction and intermittent hematuria. After exploratory laparotomy and ventral cystotomy, unilateral idiopathic renal hematuria was diagnosed based on gross observation of hematuria from the left ureteral catheter. The hematuria resolved after nephrectomy of the left kidney. The histopathological diagnosis was multifocal, acute congestion and intratubular hemorrhage. Although idiopathic renal hematuria has been described previously, this puppy was unique because the hematuria caused recurrent, complete urethral obstruction.

Idiopathic acute pancreatitis is diagnosed in approximately 10-30 % of cases of acute pancreatitis. While there is evidence to suggest that the cause in many of these patients is microlithiasis, this fact has not been translated into a resource efficient treatment strategy that is proven to reduce recurrence rates. The aim of this study was to examine the value of prophylactic cholecystectomy following an episode of acute pancreatitis in patients with no history of alcohol abuse and no stones found on ultrasound. This was a retrospective study of 2236 patients who presented to a regional Australian hospital. Patients were included when diagnosed with acute pancreatitis with no confirmed cause. Recurrence of acute pancreatitis was compared between those that did and did not undergo cholecystectomy. One hundred ninety-five consecutive patients met the study definition of "idiopathic" acute pancreatitis. 33.8 % (66/195) underwent cholecystectomy. The patients who had cholecystectomy had a recurrence rate of 19.7 % (13/66) whereas, of those managed expectantly, 42.8 % (68/159) had at least one recurrence of acute pancreatitis (P = 0.001). Following an episode of acute pancreatitis with no identifiable cause, in patients fit for surgery, cholecystectomy should be considered to reduce the risk of recurrent episodes of pancreatitis.

HLA-G, a nonclassical class-Ib gene is mainly expressed on extravillous trophoblasts at the fetal-maternal interface. HLA-G molecule is considered to play an important role in maternal immune suppression during pregnancy. The 14 bp insertion/deletion polymorphism (rs66554220) in exon eight of the HLA-G gene influences HLA-G mRNA stability and isoform splicing patterns. In this study, 202 recurrent miscarriage (RM) women with two or more than two consecutive miscarriages, their 202 partners and 204 fertile control women with at least one live birth and no miscarriages were analyzed for 14 bp insertion/deletion polymorphism. Soluble HLA-G (sHLA-G) levels were also determined and compared between randomly selected 111 RM women and 111 control women using QAYEE-Bio ELISA kits. Student's t test and χ 2 test were used to depict the statistical differences. The results showed no significant differences for 14 bp allele and genotype frequencies between the study groups. However, our study showed a significant difference (P = .0107) for sHLA-G levels in RM women and control women. Furthermore, a significant difference (P = .0135) for sHLA-G levels in relation to +/-14 bp heterozygous genotype was seen between the two groups. The 14 bp allele sharing between the partners did not show any significant association with the number of miscarriages in RM couples. The association of 14 bp polymorphism and recurrent miscarriages was not significant in our study. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Objectives l-dopa decarboxylase (DDC) is responsible for the synthesis of dopamine. Dopamine, which binds to the D2-dopamine receptor (D2R), plays an important role in the maintenance of pregnancy. Aim of our study was the analysis of DDC and D2R expression in placentas of spontaneous miscarriages (SMs) and recurrent miscarriages (RMs) in comparison to healthy controls. Methods Patients with SM (n = 15) and RM (n = 15) were compared with patients from healthy pregnancies (n = 15) (pregnancy weeks 7–13 each). Placental tissue has been collected from SMs and RMs from the first trimester (Department of Gynaecology and Obstetrics, LMU Munich) and from abruptions (private practice, Munich). Placental cell lines, BeWo- and JEG-3 cells, were stimulated with the trace amines T0AM and T1AM in vitro. Results Levels of DDC and D2R in trophoblasts and the decidua were lower in RMs in comparison to healthy controls. Stimulation of BeWo cells with T1AM significantly reduced DDC mRNA and protein levels. Via double-immunofluorescence, a DDC-positive cell type beneath decidual stromal cells and foetal EVT in the decidua could be detected. Conclusions Downregulation of DDC and D2R in trophoblasts of RMs reflects a reduced signal cascade of catecholamines on the foetal side. PMID:29686031

Objective: The aim of the study was to investigate whether the use of low molecular weight heparin (LMWH) improve live birth rates when compared with control group in patients with unexplained recurrent miscarriages (URM). Methods: In this prospective observational study 150 women with a history of two or more previous unexplained first trimester pregnancy loss who received LMWH; either enoxaparin (n=50), tinzaparin (n=50) or nothing (n=50) were followed for the pregnancy outcome measures. Only the patients who have used standardized dosage of LMWH (4000 IU/day enoxaparin or 3500 IU/day tinzaparin ) were included to the study. The primary end point was the live birth rate and secondary end points were the side effects, late pregnancy complications and neonatal outcome in the study cohorts. Results: Live birth was achieved 85% of the LMWH group and 66% of the control group (p=0.007). According to the subgroup analysis; live birth rates did not differ significantly between the enoxaparin and tinzaparin group (84% and 86%, respectively). Maternal and neonatal side effects were not statistically significant among the study participants. Conclusion: Thromboprophylaxis with LMWH resulted in a improved live-birth rate in patient with 2 or more consecutive unexplained recurrent pregnancy loss. Nevertheless these findings need to be confirmed in larger randomized trials. PMID:25674114

Abstract Combined use of heparin and aspirin is frequently prescribed for treatment of recurrent miscarriage (RM) in patients with antiphospholipid syndrome (APS), or in those without apparent cause of RM other than thrombophilia; however, this strategy is largely based on expert opinion and has not been well studied. The option for the use of different antithrombotic therapies to improve live birth remains unclear. In this network meta-analysis, we incorporated direct and indirect evidence to evaluate effects of different antithrombotic treatments on prevention of pregnancy losses. We searched PubMed and Embase for randomized clinical trials comparing effects of at least 2 antithrombotic treatments on live birth in RM patients published from 1965 through the early of May 2015. Potential risk bias of eligible trials was evaluated according to the Cochrane Collaboration guidelines. Bayesian network meta-analysis was used to estimate relative effects on live birth. A total of 19 trials involving 2391 RM patients with or without thrombophilia and 543 with APS were included. No beneficial effect of antithrombotic treatment was observed either in RM patients with or without thrombophilia or in patients with APS; however, for patients with or without thrombophilia, low molecular weight heparin therapy had the greatest probability (61.48%) of being the best option in terms of live birth; for patients with APS, unfractionated heparin plus aspirin was the superior treatment for RM with the highest possibility (75.15%) of being top 2 places for reducing pregnancy losses. Aspirin was inferior in both groups. Our results do not support the use of combined low molecular weight heparin and aspirin for RM treatment, and suggested aspirin may have negative effects for lowering the risk of pregnancy loss.

Recurrent pericarditis is a complication of acute pericarditis in 20–30% of the patients and is usually idiopathic in nature. The underlying pathogenesis of this condition remains unclear, although immune-mediated mechanisms seem likely. A subgroup of these patients with refractory symptoms can be challenging to manage, and multiple immunosuppressive medications have been used without consistent benefit. Anakinra, an interleukin-1 receptor antagonist, has been used in treatment of rheumatoid arthritis and autoinflammatory syndromes. Preliminary evidence suggests that anakinra could be a promising therapy for idiopathic recurrent pericarditis. In this narrative review, we summarize the current understanding of the etiopathogenesis of idiopathic recurrent pericarditis, mechanism of action of anakinra, and the preliminary evidence, supporting the use of anakinra in pericarditis.

Recurrent miscarriage is generally defined as three or more miscarriages before gestational week 20. Recurrent miscarriage affects 1% of all women and the condition can only be explained by parental chromosome abnormalities, uterine malformations, or endocrine or thrombophilic disturbances to a limited extent. Immunological disturbances are hypothesised to play an important role in recurrent miscarriage and, therefore, various types of immunologically-based therapies have been tested in recurrent miscarriage patients including intravenous immunoglobulins. So far, at least eight randomised placebo-controlled trials, with opposing results, investigating intravenous immunoglobulins with a total of 324 recurrent miscarriage patients have been published. We will include randomised clinical trials irrespective of publication date, publication type, publication language, and publication status investigating infusions with immunoglobulins in relation to pregnancy compared to placebo, no intervention, or treatment as usual for assessments of benefits and harms. The relevant published literature will be searched using the following databases: Cochrane Central Register of Controlled Trials, Medline, Embase, WHO International Clinical Trials Registry Platform, and Ovid Medline In-Process and Other Non-Indexed Citations databases. Two review authors will independently extract data and assess risk of bias. We will undertake meta-analyses according to the recommendations stated in the Cochrane Handbook for Systematic Reviews of Interventions. Further, we will conduct trial sequential analyses and individual patient data meta-analyses. A miscarriage results in great sorrow, loss of life quality, and personal concern. In particular, recurrent miscarriage is extremely stressful and burdensome. It is, therefore, very important to conduct research in this area. There is currently no evidence-based treatment for women with recurrent miscarriage which significantly improves their

The term "miscarriage" refers to the end of pregnancy before the 22nd week of gestation, or taking into account the criterion of foetal weight (less than 500 g). Approximately 15-20% of recognized pregnancies and miscarriage involve spontaneous expulsion of the blastocyst from the uterine cavity. This constitutes about 80% of miscarriages in the first 12 weeks of gestation. The literature lists a number of factors which cause the loss of pregnancies. The most frequently cited causes of abortion are: genetic, anatomical, immunological and hormonal factors, and infections. A large number of miscarriages remain unexplained (idiopathic miscarriages). Clinical signs of miscarriage include bleeding and pain. Bleeding or spotting is the earliest sign of miscarriage. Data from the patient's history, physical examination, ultrasound examination and tests for hCG level can enable diagnosis of bleeding in early pregnancy, help to assess the degree of risk, and implement an appropriate treatment regimen and care for pregnant women adapted to their needs. Loss of pregnancy is an interdisciplinary problem involving obstetrics, epidemiology, public health, psychology, and other specialities. The role of medical personnel in the care of women after the loss of a child, regardless of the week and therapeutic procedures, as well as for giving adequate information regarding the rights of women after pregnancy loss. The obligation to inform women of their rights concerns medical staff, and it is important to promote knowledge in this field among doctors, nurses and midwives who care for women after miscarriage.

We have previously hypothesized that early miscarriage in women with Hashimoto thyroiditis might be the result of a cross-reactivity process, in which blocking autoantibodies against thyrotropin receptor (TSHr-Ab) antagonize hCG action on its receptor on the corpus luteum. To test this hypothesis from the clinical perspective, we investigated the presence of TSHr-Ab in Hashimoto thyroiditis patients with apparently unexplained, first-trimester recurrent miscarriages compared to that in Hashimoto thyroiditis patients with documented normal fertility. A total of 86 subjects (43 cases and 43 age-matched controls) were finally included in a case-control study. No difference in the prevalence of TSHr-Ab positivity was detected between cases and controls (Fisher's exact test, p value = 1.00). In patients with recurrent miscarriages, TSHr-Ab concentrations did not predict the number of miscarriages (univariate linear regression, p value = 0.08). These results were robust in sensitivity analyses, including only cases with full investigation or those with three or more miscarriages. We conclude that no role could be advocated for TSHr-Ab in the aetiology of recurrent miscarriages in women with Hashimoto thyroiditis.

The development of pregnancy is possible due to initiation of immune response in the body of the mother resulting in immune tolerance. Miscarriage may be caused by the impaired maternal immune response to paternal alloantigens located on the surface of trophoblast and fetal cells. The aim of the study was to compare the population of circulating dendritic cells (DCs) and CD4+CD25+Foxp3+ regulatory T cells (TREGs) in the first trimester of a normal pregnancy and in women with recurrent miscarriage and an attempt to determine the relationship between these cells and the role they may play in human reproductive failures. The study was conducted in a group of 33 first trimester pregnant women with recurrent miscarriage and in a group of 20 healthy pregnant women in the first trimester of normal pregnancy. Among mononuclear cells isolated from peripheral blood, the populations of DCs and TREGs were assessed by flow cytometry. The percentage of myeloid DCs and lymphoid DCs showed no significant difference between study and control group. Older maternal age and obesity significantly reduced the pool of circulating myeloid and lymphoid DCs (R=-0.39, p=0.02). In miscarriages the percentage of circulating TREGs was significantly lower compared to normal pregnancies (p=0.003). Among the analysed factors the percentage of TREGs was the most sensitive and the most specific parameter which correlated with the pregnancy loss. The reduction in the population of circulating TREGs suggests immunoregulatory mechanisms disorder in a pregnancy complicated by miscarriage. PMID:25945787

Idiopathic recurrent pericarditis as an immune-mediated disease: current insights into pathogenesis and emerging treatment options.

PubMed

Imazio, Massimo

2014-11-01

Idiopathic recurrent pericarditis affects 30-50% of patients with a previous attack of pericarditis. The etiopathogenesis is incompletely understood and most cases remain idiopathic with a presumed immune-mediated pathogenesis. The mainstay of therapy is aspirin or a nonsteroidal anti-inflammatory drug plus colchicine and the possible adjunct of a low-to-moderate dose of a corticosteroid in more difficult cases. Colchicine as an adjunct to anti-inflammatory therapy reduces by 50% the subsequent recurrent rate. For true refractory cases with failure of standard combination therapies, new and emerging options especially include human intravenous immunoglobulins and biological agents (i.e., anakinra). The outcome of idiopathic recurrent pericarditis is good with a negligible risk of developing constrictive pericarditis. Thus, it is important to reassure patients on their prognosis, explaining the nature of the disease and the likely course. Moreover, therapeutic choices should include less toxic agents and favor cheaper drugs whenever possible.

To investigate the association between polymorphisms in genes that encode enzymes involved in folate- and vitamin B12-dependent homocysteine metabolism and recurrent spontaneous abortion (RSA). We investigated the C677T and A1298C polymorphisms of the methylenetetrahydrofalate reductase gene (MTHFR), the A2756G polymorphism of the methionine synthase gene (MS) and the 844ins68 insertion of the cystathionine beta synthetase gene (CBS). The PCR technique followed by RFLP was used to assess the polymorphisms; the serum levels of homocysteine, vitamin B12 and folate were investigated by chemiluminescence. The EPI Info Software version 6.04 was used for statistical analysis. Parametric variables were compared by Student's t-test and nonparametric variables by the Wilcoxon rank sum test. The frequencies of gene polymorphisms in 89 women with a history of idiopathic recurrent miscarriage and 150 controls were 19.1 and 19.6% for the C677T, insertion, 20.8 and 26% for the A1298C insertion, 14.2 and 21.9% for the A2756G insertion, and 16.4 and 18% for the 844ins68 insertion, respectively. There were no significant differences between case and control groups in any of the gene polymorphisms investigated. However, the frequency of the 844ins68 insertion in the CBS gene was higher among women with a history of loss during the third trimester of pregnancy (p=0.003). Serum homocysteine, vitamin B12 and folate levels id not differ between the polymorphisms studied in the case and control groups. However, linear regression analysis showed a dependence of serum folate levels on the maintenance of tHcy levels. The investigated gene polymorphisms and serum homocysteine, vitamin B12 and folate levels were not associated with idiopathic recurrent miscarriage in the present study. Further investigations are needed in order to confirm the role of the CBS 844ins68 insertion in recurrent miscarriage.

One percent of couples trying to have children are affected by recurrent miscarriage. These pregnancy losses have different pathogenetic (genetic, endocrine, anatomic, immunologic, microbiologic, haematologic and andrologic) backgrounds, but recurrent miscarriage remains unexplained in more than half of the affected couples. To explore risk factors for recurrent pregnancy loss the authors studied the incidence of anatomic disorders of the uterine cavity occur in Hungarian women with recurrent miscarriage. Medical records of 152 patients with recurrent miscarriage were analyzed retrospectively. In order to explore disorders of the uterine cavity hysteroscopy or 3-dimensional sonography in 132 women, hysterosalpingography in 16 and hysterosalpingo-sonography in 4 patients were used. Incidence of anomalies in the uterine cavity was found in women with recurrent miscarriage to be 15.8%. A variety of the uterine anomalies was found including uterine septum in 6.5%, endometrial polyp in 2.6%, arcuate and bicornuate uteri both in 2% and 2%, submucosal myoma in 1.3 %, and intrauterine synechiae in 1.3%. These findings suggest that morphologic disorder of the uterine cavity is frequent in Hungarian women with recurrent miscarriage. Therefore, assessment of the uterine anatomy is recommended in such patients.

This is a retrospective, observational study to determine how often repeated consecutive miscarriages occur consistently in the same gestational period, including 1589 miscarriages among 543 women with recurrent miscarriage. In women who had two miscarriages only, 49.17% of both miscarriages occurred in the same gestational period, which was significantly higher than the expected probability of 34.54% (P<0.01). The proportions of all miscarriages occurring in the same gestational period in women with three, four and five or more miscarriages were 28.72%, 19.44% and 18.60%, compared with the expected probabilities of 14.36% (P<0.01), 6.57% (P<0.05) and <3.15% (P<0.05). The proportions of miscarriages occurring consistently in the same gestational period are higher than the theoretical probabilities calculated for the whole population.

Although idiopathic acute pericarditis is usually a self-limiting disease, in many patients it may recur over a period of months or years. Even if some evidence seems to suggest the possible role of a deranged immune reactivity in the pathogenesis of idiopathic recurrent pericarditis, the etiology of the disease is still unknown. Furthermore, while some trial data confirm the usefulness of colchicine, its medical treatment is not yet clearly established. We here report the clinical history of 2 patients with idiopathic recurrent pericarditis resistant to prednisone, colchicine and other immunosuppressive drugs, who have been successfully treated with high-dose intravenous immunoglobulins.

Will the addition of 24-chromosome microarray analysis on miscarriage tissue combined with the standard American Society for Reproductive Medicine (ASRM) evaluation for recurrent miscarriage explain most losses? Over 90% of patients with recurrent pregnancy loss (RPL) will have a probable or definitive cause identified when combining genetic testing on miscarriage tissue with the standard ASRM evaluation for recurrent miscarriage. RPL is estimated to occur in 2-4% of reproductive age couples. A probable cause can be identified in approximately 50% of patients after an ASRM recommended workup including an evaluation for parental chromosomal abnormalities, congenital and acquired uterine anomalies, endocrine imbalances and autoimmune factors including antiphospholipid syndrome. Single-center, prospective cohort study that included 100 patients seen in a private RPL clinic from 2014 to 2017. All 100 women had two or more pregnancy losses, a complete evaluation for RPL as defined by the ASRM, and miscarriage tissue evaluated by 24-chromosome microarray analysis after their second or subsequent miscarriage. Frequencies of abnormal results for evidence-based diagnostic tests considered definite or probable causes of RPL (karyotyping for parental chromosomal abnormalities, and 24-chromosome microarray evaluation for products of conception (POC); pelvic sonohysterography, hysterosalpingogram, or hysteroscopy for uterine anomalies; immunological tests for lupus anticoagulant and anticardiolipin antibodies; and blood tests for thyroid stimulating hormone (TSH), prolactin and hemoglobin A1c) were evaluated. We excluded cases where there was maternal cell contamination of the miscarriage tissue or if the ASRM evaluation was incomplete. A cost analysis for the evaluation of RPL was conducted to determine whether a proposed procedure of 24-chromome microarray evaluation followed by an ASRM RPL workup (for those RPL patients who had a normal 24-chromosome microarray evaluation

A Cross Sectional population based serological studies was conducted to determine the prevalence and associated risk factors for syphilis women with recurrent miscarriages. Patient's 5ml whole blood was collected through venepuncture technique. Data were collected by all women answered a questionnaire and by investigating blood sample VDRL test and FTA-ABS test. The study was conducted in a confidential manner and numbers were used to identify the participant. Total 256 women were included in the present study. Mean age of women was 29.4 years while range was 21 to 38 years (206/256). Out of the 256 samples, 05 (1.9%) were positive for active syphilis. Majority belonged to low socioeconomic group, uneducated and had previous congenital anomaly. Active infection with Treponema pallidum (T.P) in women belonging to low socioeconomic level were disquieting. This is probably due to illiteracy and high proportion of unsafe sexual behavior. It is also suggestive that seropositive status is often discovered in routine serological studies during pregnancy.

Objective Idiopathic granulomatous mastitis is a breast disease without a definitive etiology. There are no definitive classifications, scoring systems or certitudes. The aim of this study is to define the factors related to the recurrence and design a scoring system. Material and Methods Patients who were admitted to the general surgery department with symptoms of granulomatous mastitis were evaluated by ultrasonography and underwent antibiotic therapy. Granulomatous mastitis is diagnosed by core biopsy and treated with steroid therapy. Patients without improvement underwent surgery and were included in the study. In total, 53 patients were included in the study. There were 8 recurrent cases. Factors related with recurrences were defined. Results Number of births over 2, duration of lactation more than 18 months, body mass index greater than 31, having fistula in physical examination, abscess collection in ultrasonographic examination, and luminal inflammation score over 2 were scored as 1. Severity score in recurrent cases were 5.1±0.6 whereas 1.9±1.0 in nonrecurrent cases. Conclusion Granulomatous mastitis score is a tool targeted at predicting the risk of recurrences. The patients with these factors are more prone for recurrences. PMID:29774320

To identify gene mutations in PRSS1 and SPINK1 in individuals with early onset idiopathic chronic or recurrent acute pancreatitis. The cationic trypsinogen gene (PRSS1; exons 2 and 3) and the serine protease inhibitor Kazal 1 gene (SPINK1; exon 3) were selectively amplified and sequenced from blood samples of 19 patients admitted to the Pancreas Clinic at our institution with chronic pancreatitis and/or idiopathic recurrent acute pancreatitis that were diagnosed or with onset before age 35. Fifty healthy volunteers served as controls. Whole blood samples were collected and gene specific sequences were amplified by polymerase chain reaction (PCR). All PCR products were subsequently sequenced in order to identify the presence of any mutations. Nineteen patients with pancreatitis (14 males; median age 24 years, range 15-48 years) were included in this study, of which five showed the presence of gene mutations. Direct sequencing results indicated the presence of two previously unidentified mutations in exon 2 of PRSS1 (V39E and N42S) in two patients with recurrent acute pancreatitis. Two cases had the N34S SPINK1 mutation. Analysis of the relatives of one patient homozygous for this mutation showed that five of the six family members carried the N34S SPINK1 mutation. Of these members, three were healthy heterozygous carriers and two were homozygotes (one sibling had diabetes, the other was healthy). Another patient was heterozygous for a novel SPINK1 mutation located on exon 3 (V46D). All members from this patient's family had normal genotypes, indicating that it was a de novo mutation. No mutations in either gene were present in the control subjects. Two novel PRSS1 mutations and one novel SPINK1 mutation were identified in Mexican patients with early onset idiopathic recurrent acute pancreatitis.

We report on the risk of miscarriage with high- and low-dosage periconceptional folic acid (FA) supplementation from a double-blind randomized clinical trial for prevention of orofacial cleft recurrence in Brazil. Women at risk of recurrence of orofacial clefts in their offspring were randomized into high (4 mg/day) and low (0.4 mg/day) doses of FA supplementation. The women received the study pills before pregnancy, and supplementation continued throughout the first trimester. Miscarriage rates were compared between the two FA groups and with the population rate. A total of 268 pregnancies completed the study protocol, with 141 in the 4.0-mg group and 127 in the 0.4-mg group. The miscarriage rate was 14.2% in the low-dose FA group (0.4 mg/day) and 11.3% for the high-dose group (4 mg/day) (P=0.4877). These miscarriage rates are not significantly different from the miscarriage rate in the Brazilian population, estimated to be around 14% (P=0.311). These results indicate that high-dose FA does not increase miscarriage risk in this population and add further information to the literature on the safety of high FA supplementation for prevention of birth defect recurrence.

The purpose of this study was to quantify spontaneous first trimester miscarriage rates per woman among parous women. A vast amount of data has accumulated regarding miscarriage rates per recognized pregnancy as well as about recurrent miscarriage. This is the second study of miscarriage rates per woman in a parous population and the first study of recurrent and non-recurrent, spontaneous first trimester miscarriage rates per woman in a large parous population. Extraction of the following variables from all delivery room admissions from both Hadassah Medical Centers in Jerusalem Israel, 2004-2014: # of first trimester spontaneous miscarriages, # live births; # living children; age on admission, pre-pregnancy height and weight, any smoking this pregnancy, any alcohol or drug abuse this pregnancy, blood type, history of ectopic pregnancy, history of cesarean surgery (CS) and use of any fertility treatment(s). Among 53,479 different women admitted to labor and delivery ward, 43% of women reported having had 1 or more first trimester spontaneous miscarriages; 27% reported having had one, 10% two, 4% three, 1.3% four, 0.6% five and 0.05% reported having 6-16 spontaneous first trimester miscarriages. 18.5% had one or more first trimester miscarriages before their first live birth. Eighty-one percent of women with 11 or more living children experienced one or more first trimester miscarriages. First trimester miscarriage rates rose with increasing age, increasing parity, after previous ectopic pregnancy, after previous cesarean surgery, with any smoking during pregnancy and pre-pregnancy BMI ≥30. Miscarriages are common among parous women; 43% of parous women report having experienced one or more first trimester spontaneous miscarriages, rising to 81% among women with 11 or more living children. One in every 17 parous women have three or more miscarriages. Depending on her health, nutrition and lifestyle choices, even a 39 year old parous woman with a history of 3 or

The purpose of this study was to determine the frequency and distribution of cytogenetically abnormal miscarriages in couples with spontaneous abortions (SA) or recurrent miscarriages (RM). Karyotyping of specimens from 164 abortuses with SA and 86 abortuses with RM was successfully performed according to the standard cytogenetic methods using G-banding technique. Among the total 164 cases of SA group, 81 (49.4%) were euploid and the rest (83, 50.6%) showed chromosomal abnormalities. In RM(≥2) and RM(≥3) group, 31 (36.0%)/27 (34.6%) cases were euploid and 55 (64.0%)/51(65.4%) cases were abnormal, respectively. A statistically significant difference was found in the rate of cytogenetic abnormality between SA and RM groups (P<0.05). In all groups, women with advanced maternal age (≥35 years) had a higher rate of chromosome anomalies compared with women younger than age 35 (normal:abnormal = 32.4%:67.6% for ≥35 years and 53.8%:46.2% for <35 years in SA; 19.2%:80.8%/21.7%:78.3% for ≥35 years and 43.3%:56.7%/40.0%:60.0% for <35 years in RM(≥2) and RM(≥3), respectively; P<0.05). In SA group, an increase of normal karyotypes was noted with increased gestational age (<10 week, 38.0%; 10-15 week, 53.5%; 16-20 week, 65.7%). In RM group, most of cases were in <10 week and the frequency of trisomies with chromosomes 1 to 10 were increased compared with that of SA. There was a statistically significant difference in the frequency and distribution of chromosomal abnormalities between SA and RM groups. Our results will provide useful information for diagnosis and genetic counseling of patients with SA or RM.

Acute recurrent pancreatitis (ARP) is defined as more than two attacks of acute pancreatitis with complete or almost complete resolution of symptoms and signs of pancreatitis between episodes. The initial evaluation fails to detect the cause of ARP in 10%-30% of patients, whose condition is classified as idiopathic ARP. Endoscopic ultrasound (EUS) has gained increasing attention as a useful imaging modality for the pancreas and the extrahepatic biliary tree. The close proximity of the pancreas to the digestive tract allows EUS to obtain detailed images of this organ. This review aims to record pancreaticobiliary endoscopic ultrasound (EUS) and other imaging modalities in the clinical management of patients with idiopathic ARP.

Immunosuppression at the feto-maternal interface is crucial for a successful pregnancy outcome. Human leukocyte antigen-G (HLA-G) seems to be a major contributor to fetal tolerance. The HLA-G expression is seen in cytotrophoblasts and in maternal blood. Fetal HLA-G acts on decidual antigen-presenting cells (APCs), natural killers (NKs) and T cells. Recent findings revealed that defects in placentation and their consequences are associated with maternal HLA-G variants and their expression levels. The objective of this article is to investigate the relationship between fetal HLA-G alleles and miscarriage, which has not been investigated to date. The present study includes 204 recurrent miscarriage (RM) cases who were admitted to our clinic between 2012 and 2016. Twenty-eight miscarriage products without maternal cell contamination and any known pathology were analyzed by HLA-G typing. In addition, 3' untranslated region (UTR) 14-base pair (bp) insertion/deletion polymorphism was also investigated by Sanger sequencing. For our population, the most frequent HLA-G type was G*01:01, both in the study group (30.3%) and in the control group (47%). The study revealed that the G*01:04 allele was significantly associated with miscarriage (p = 0.007). The 3' UTR 14bp deletion was more frequent in the miscarriage group, but there was no significant correlation. HLA-G alleles seem to be related with miscarriage and should be considered in RM cases.

2016-03-01

Idiopathic recurrent pericarditis (IRP) is a debilitating illness which leads to great suffering and multiple hospitalizations. Management of acute pericarditis and subsequent recurrences has evolved significantly as the use of colchicine-based strategies become more prevalent, yet there still remains a subset of patients who remain refractory to colchicine therapy, and these patients require prolonged corticosteroid (CS) therapy for the control of symptoms. Since the 1960s, there have been reports of successful management of these cases with immunosuppressive therapy. Current guidelines support the use of anakinra, intravenous immunoglobulins, and azathioprine for management of IRP, with the goals of both control of symptoms and withdrawal of CS. Recent reports supply evidence for both auto-inflammatory and autoimmune activity in these patients. We herein review the current available reports regarding the evidence regarding the pathophysiology and reported cases and case series of IRP cases managed with immunomodulation therapy.

Embryonic growth is often impaired in miscarriages. It is postulated that derangements in embryonic growth result in abnormalities of the embryonic curvature. This study aims to create first trimester reference charts of the human embryonic curvature and investigate differences between ongoing pregnancies and miscarriages. Weekly ultrasonographic scans from ongoing pregnancies and miscarriages were used from the Rotterdam periconceptional cohort and a cohort of recurrent miscarriages. In 202 ongoing pregnancies and 33 miscarriages, first trimester crown rump length and total arch length were measured to assess the embryonic curvature. The results show that the total arch length increases and shows more variation with advanced gestation. The crown rump length/total arch length ratio shows a strong increase from 8 +0 to 10 +0 weeks and flattening thereafter. No significant difference was observed between the curvature of embryos of ongoing pregnancies and miscarriages. The majority of miscarried embryos could not be measured. Therefore, this technique is too limited to recommend the measurement of the embryonic curvature in clinical practice. Copyright © 2018 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

To analyze the efficacy of induced macular detachment for the treatment of persistent or recurrent idiopathic macular holes after treatment with one or more standard pars plana vitrectomies (PPVs) with internal limiting membrane peeling. This study is a retrospective consecutive case series of 10 patients who underwent a PPV with subretinal balanced salt solution injection from 2011 to 2014 to treat persistent or recurrent idiopathic macular holes. All patients had previously undergone PPV with internal limiting membrane peeling. Visual acuity, ocular examination findings, and optical coherence tomographic images were reviewed preoperatively and postoperatively to assess the anatomical and visual outcomes of this procedure. Nine of the 10 patients who underwent the procedure had closure of their macular holes postoperatively (90%) and remained closed 6 months postoperatively. Most patients reported a subjective visual improvement. A mean objective visual improvement of 16 letters (Early Treatment Diabetic Retinopathy Study, 0.324 logMAR) was seen between preoperative and 6-month postoperative assessments of all patients (pre = 1.490, post = 1.166; P = 0.022). Subgroup analysis of patients with successful closure revealed 20 letters of improvement (0.398 logMAR) in visual acuity (pre = 1.491, post = 1.093; P = 0.004). There were no intraoperative or postoperative complications. In eyes with persistent or recurrent idiopathic macular holes after standard PPV with internal limiting membrane peeling, repeat PPV with subretinal balanced salt solution injection to create a macular detachment may be a viable surgical treatment option. Our results show improved anatomical and visual outcomes postoperatively that compare favorably to other case series describing various surgical treatments for these challenging cases.

Background: Genetic factors are the main cause of early miscarriage. This study aimed to investigate aneuploidy in spontaneous abortion by fluorescence in situ hybridization (FISH) using probes for 13, 16, 18, 21, 22, X and Y chromosomes. Methods: A total of 840 chorionic samples from spontaneous abortion were collected and examined by FISH. We analyzed the incidence and type of abnormal cases and sex ratio in the samples. We also analyzed the relationship between the rate of aneuploidy and parental age, the rate of aneuploidy between recurrent abortion and sporadic abortion, the difference in incidence of aneuploidy between samples from previous artificial abortion and those from no previous induced abortion. Results: A total of 832 samples were finally analyzed. 368 (44.23%) were abnormal, in which 84.24% (310/368) were aneuploidies and 15.76% (58/368) were polyploidies. The first was trisomy16 (121/310), followed by trisomy 22, and X monosomy. There was no significant difference in the rate of aneuploidy in the advanced maternal age group (≥35 years old) and young maternal age group (<35 years old). However, the rate of trisomy 22 and the total rate of trisomies 21, 13, and 18 (the number of trisomy 21 plus trisomy 13 and trisomy 18 together) showed significantly different in two groups. We found no skewed sex ratio. There was no significant difference in the rate of aneuploidy between recurrent miscarriage and sporadic abortion or between the samples from previous artificial abortion and those from no previous artificial abortion. Conclusions: Aneuploidy is a principal factor of miscarriage and total parental age is a risk factor. There is no skewed sex ratio in spontaneous abortion. There is also no difference in the rate of aneuploidy between recurrent abortion and sporadic abortion or between previous artificial abortion and no previous induced abortion. PMID:26481744

Kaur, Ramandeep; Gupta, Kapil

2016-01-01

Miscarriage is the spontaneous loss of a fetus before it is viable, occurring at a rate of 15–20%. Recurrent spontaneous abortion (RSA) or habitual miscarriage is defined as repeated occurrence of 3 or more miscarriages before 20th week of gestation accounting for the most common complication of early pregnancy in humans. Various etiological factors responsible for recurrent miscarriage are anatomical, genetical, endocrinological, immunological, and infectious. The endocrinological abnormalities may be polycystic ovarian syndrome, hyperprolactinemia, luteal phase defect, thyroid dysfunction, diabetes, or hyperandrogenism contributing to recurrent pregnancy loss. In the present article, the role of endocrinological disorders in patients with RSA has been reviewed. The article search was done using electronic databases, Google scholarly articles, and PubMed based on different key words. We have further combined the searches and made grouping as per various endocrine abnormalities, which might be responsible to cause spontaneous loss of fetus. PMID:27127734

Physiological studies in animals and human support an important role of circadian system in reproduction. The aim of this study was to investigate the potential association of CLOCK gene polymorphisms with idiopathic recurrent spontaneous abortion (IRSA). We performed a case-control study. The study group consisted of 268 women with a history of three or more idiopathic recurrent spontaneous abortions and 284 women with at least two live births and no history of pathologic pregnancies all from Slovenia and Serbia. Two SNPs in the CLOCK gene were chosen and genotyped. The results showed a statistically significant difference in genotype distribution between the two groups in the CLOCK gene for rs6850524 and rs11932595. Our analysis showed that G allele under dominant model (GG+GC/CC) for rs6850524 (p = 2∙10-4, OR = 2.28, 95%CI = 1.46-3.56) as well as G allele under dominant model (GA+AA/AA) for rs11932595 (p = 0.04, OR = 1.47, 95%CI = 1.01-2.04) might be risk factors against IRSA. Our data suggest that genetic variability in the CLOCK gene is associated with IRSA warranting further confirmation and mechanistic investigations.

Thrombophilias are suggested to play a role in recurrent miscarriage. The aim of this study was to evaluate the literature of the past 10 years regarding the association between thrombophilias and recurrent miscarriage. We concluded that there is a large variety in applied study methodology. Therefore, we defined criteria for an adequate study on the relationship of thrombophilias on recurrent pregnancy loss: (i) no exclusion criteria for patients or at least the same criteria for patients and controls; (ii) a clear definition of the gestational age at previous losses; (iii) a well-described control group; (iv) clear description of the test methods and moment of testing; and (v) a clear description of the (non) significant differences or odds ratio between cases and controls. Eleven out of 69 studies fulfilled these criteria. Their results show significant higher serum homocysteine levels among women with a history of recurrent miscarriage. No relation was found between recurrent miscarriage and the methylenetetrahydrofolate reductase C667T mutation. No relation was observed for the levels of antithrombin, protein C and protein S. Seven studies on the association of factor V Leiden (FVL) and/or pathologic activated protein C ratio (pAPCR) showed that FVL may play a role in second trimester losses, as do antiphospholipid antibodies. Studies on the prothrombin gene mutation yielded conflicting results. Consequently, large prospective studies according to the aforementioned criteria are needed to establish if there is a relationship between thrombophilias and recurrent miscarriage at all. At present, there is only justification for testing for homocysteine levels, antiphospholipid antibodies and FVL in women with a history of recurrent miscarriage.

Idiopathic bone cavities of the mandible: an update on recurrence rates and case report.

Idiopathic bone cavities (IBCs) are usually an incidental finding, often found in long bones but also in the craniofacial skeleton. Typically solitary, IBCs can present at multiple sites. Surgical exploration alone has proved effective, although recurrence does occur, particularly in cases with multiple lesions. The average time necessary to observe either recurrence or complete healing has been reported to be more than 3 years. Previously reported low recurrence rates for IBCs in the craniofacial skeleton may have been artificially low because of insufficient long-term follow-up. Providers should be prepared for long-term follow-up and care of these patients. The case of the patient presented here supports the need for long-term follow-up. Copyright © 2014 Elsevier Inc.

Recurrent pregnancy loss (RPL) or recurrent spontaneous abortion is an obstetric complication that affects couples at reproductive age. Previous reports documented a clear relationship between parents with chromosomal abnormalities and both recurrent miscarriages and infertility. However, limited data is available from the Arabian Peninsula which is known by higher rates of consanguineous marriages. The main goal of this study was to determine the prevalence of chromosomal abnormalities and thrombophilic polymorphisms, and to correlate them with RPL and consanguinity in Saudi Arabia. Cytogenetic analysis of 171 consent patients with RPL was performed by the standard method of 72-h lymphocyte culture and GTG banding. Allelic polymorphisms of three thrombophilic genes (Factor V Leiden, Prothrombin A20210G, MTHFR C677T) were performed using PCR-RFLP (restriction fragment length polymorphism) and gel electrophoresis. Data analysis revealed that 7.6 % of patients were carrier of numerical or structural chromosomal abnormalities. A high rate of translocations (46 %) was associated to increased incidence of RPL. A significant correlation between consanguineous RPL patients and chromosomal abnormalities (P < 0.05) was found. Both Factor V Leiden and Prothrombin A20210G allelic polymorphisms were significantly associated with a higher prevalence of RPL. This study demonstrated a strong association between RPL and the prevalence of chromosomal abnormalities and inherited thrombophilia. Given the high rate of consanguineous marriages in the Saudi population, these results underline the importance of systematic cytogenetic investigation and genetic counseling preferably at the premarital stage or at least during early pregnancy phase through preimplantation genetic diagnosis (PGD).

Power Doppler in combination with three-dimensional (3D-PD) ultrasonography has been used as a noninvasive tool to evaluate the vascularity. However, it is unclear whether 3D-PD can accurately reflect endometrial vascularization and replace the invasive endometrial biopsy. This study aims to investigate the correlation between 3D-PD and micro vessel morphometric measurement of endometrial vascularity. Twenty-five women with unexplained recurrent miscarriage were recruited for 3D-PD and endometrial biopsy on precisely day LH + 7. Immunohistochemistry using vWF was employed to identify micro vessels in endometrial biopsy specimens followed by the use of morphometric technique to measure the mean vessel diameter and volume fractions. The vascularization index (VI), flow index (FI) and vascularization flow index (VFI) assessed by 3D-PD were calculated for both the endometrial and sub-endometrial regions. There were no significant correlations between any of the ultrasonographic measurements (endometrial thickness, endometrial volume, endometrial VI/FI/VFI, sub-endometrial volume, sub-endometrial VI/FI/VFI) and morphometric features (number of micro vessel, mean diameter of micro vessel and volume fraction measurement of vessel). This study indicates that endometrial vascularity assessed by 3D-PD could not be used to reflect changes in micro vessels of the endometrium at the time of embryo implantation in women with unexplained recurrent miscarriage.

Objectives Thyroid hormones play an important role in the maintenance of pregnancy. Their derivates, endogenous amines, act via binding to the trace amine-associated receptor (TAAR1). The aim of our study was to analyse the regulation of TAAR1, serine/threonine kinase (pGSK3β) and ornithine decarboxylase (ODC) in placentas of healthy pregnancies, spontaneous (SM) and recurrent miscarriages (RM) and to investigate the influence of thyroid hormone derivates on TAAR1 expression in trophoblast model cells in vitro. Methods Patients with SM (n = 15) and RM (n = 15) were compared with patients with healthy pregnancies (n = 15) (pregnancy weeks 7–13 each). Immunohistochemistry was applied to analyse placental TAAR1, pGSK3β and ODC expression. Protein expression of the receptors after stimulation with T3, T1AM and RO5203548 in BeWo trophoblast model cells was determined via Western blot. Double-immunofluorescence was used to determine placental expression of TAAR1 and ODC. Results Levels of TAAR1, pGSK3β and ODC were higher in placentas of RM in comparison to healthy controls. Stimulation of BeWo cells with T3, T1AM and RO5203548 significantly increased TAAR1 expression. ODC expression in BeWo cells was upregulated through T3. Via double-immunofluorescence, TAAR1 and ODC-positive EVT could be detected. Conclusions Upregulation of placental TAAR1 may indicate an increased decarboxylation of thyroid hormones in miscarriages. Patients with RM may have a lack of T3 through an enhanced transformation of T3 into T1AM induced by the ODC. Future investigations could be carried out to analyse what role a prophylactic T3 substitution plays for patients. PMID:29472377

Accumulating evidence suggests idiopathic recurrent pericarditis as a disease of probable autoinflammatory origin, and thus anakinra could be of benefit. The goal of this systematic review was to assess the efficacy and safety of anakinra in this context. Reports relevant to anakinra administration in patients with idiopathic recurrent pericarditis published up to October 2014 were searched in several databases. All references found, upon initial assessment at title and abstract level for suitability, were consequently retrieved as full reports for further appraisal. Among 12 citations retrieved, nine reports (four case series and five case reports with 34 patients, 20 men, mean age 26.8 years) were assessed. The mean disease duration was 31 months and the number of recurrences 8.2. Anakinra was generally administered as a daily subcutaneous injection of 100 mg or as a mean dose of 1.1 mg/kg/d in weight-adjusted regimens. The mean full-dose duration was 9.2 months. C-reactive protein normalized within 7.1 days, and steroids were withdrawn within 62 days. Dose tapering was adopted in 64.7% of patients, leading to recurrence in 26% of cases. In a 28.3-month follow-up, eight out of 34 patients (23.5%) were disease free without treatment, after having received anakinra for 10.4 months overall. Anakinra was proved well tolerated, with mild local reaction being reported in 44% of patients. Anakinra is a highly effective, rapidly acting, well tolerated and steroid-sparing agent. Recurrences after drug discontinuation are a matter of concern. Randomized trials are required to confirm these findings and address the most effective treatment protocol.

The aim of this study was to investigate the potential association of CLOCK gene polymorphisms with idiopathic recurrent spontaneous abortion (IRSA). We performed a case-control study. The study group consisted of 268 women with a history of three or more idiopathic recurrent spontaneous abortions and 284 women with at least two live births and no history of pathologic pregnancies all from Slovenia and Serbia. Two SNPs in the CLOCK gene were chosen and genotyped. The results showed a statistically significant difference in genotype distribution between the two groups in the CLOCK gene for rs6850524 and rs11932595. Our analysis showed that G allele under dominant model (GG+GC/CC) for rs6850524 (p = 2∙10−4, OR = 2.28, 95%CI = 1.46–3.56) as well as G allele under dominant model (GA+AA/AA) for rs11932595 (p = 0.04, OR = 1.47, 95%CI = 1.01–2.04) might be risk factors against IRSA. Our data suggest that genetic variability in the CLOCK gene is associated with IRSA warranting further confirmation and mechanistic investigations. PMID:29768442

This study seeks to establish progesterone and progesterone-induced blocking factor (PIBF) levels as predictors of subsequent completed miscarriage among women presenting with threatened miscarriage between 6 and 10 weeks of gestation. Our secondary objective was to assess the known maternal risk factors, toward development of a parsimonious and clinician-friendly risk assessment model for predicting completed miscarriage. In this article, we present a prospective cohort study of 119 patients presenting with threatened miscarriage from gestation weeks 6 to 10 at a tertiary women's hospital emergency unit in Singapore. Thirty (25.2%) women had a spontaneous miscarriage. Low progesterone and PIBF levels are similarly predictive of subsequent completed miscarriage. Study results (OR, 95% CI) showed that higher levels of progesterone (0.91, 95% CI 0.88-0.94) and PIBF (0.99, 95% CI 0.98-0.99) were associated with lower risk of miscarriage. Low progesterone level was a very strong predictor of miscarriage risk in our study despite previous concerns about its pulsatile secretion. Low serum progesterone and PIBF levels predicted spontaneous miscarriage among women presenting with threatened miscarriage between gestation weeks 6 to 10. Predictive models to calculate probability of spontaneous miscarriage based on serum progesterone, together with maternal BMI and fetal heart are proposed.

We aimed to investigate the modulatory effects of vitamin D on peripheral blood cellular immune response in patients with recurrent miscarriage (RM). The effect of vitamin D on the number of peripheral blood cells, T helper 1 (Th1) cytokines, and NK cytotoxicity was measured in 99 women with RM. The percentage of CD19 + B cells and NK cytotoxicity at an effector-to-target cell (E:T) ratio of 50:1, 25:1, and 12.5:1 were significantly higher in the vitamin D insufficiency group (VDI) than in the vitamin D normal group (VDN) (P<.05 each). The proportion of TNF-α-expressing Th cells was significantly higher in the vitamin D deficiency group (VDD) than in VDN (P<.05). However, there were no significant differences between VDI and VDD. This dysregulation was significantly reduced with 1,25(OH) 2 D supplementation. The data suggest that the abnormalities of cellular immune response were observed in RM patients with a low vitamin D level, which could be regulated to some extent with 1,25(OH) 2 D supplementation. © 2016 John Wiley & Sons A/S.

Recently, several investigations concerning disadvantageous genetic factors in human reproduction have progressed. Inherited thrombophilia, such as factor V Leiden, prothrombin, and methylenetetrahydrofolate reductase mutations; gene polymorphisms of detoxification enzyme (CYP1A1); growth factors (insulin-like growth factor-I); and hormones such as angiotensinogen and CYP17 are involved in the pathogenesis of fetal growth restriction. The inherited thrombophilia, gene polymorphisms of coagulation and anticoagulation factor such as thrombomodulin, endothelial protein C receptor, plasminogen activator inhibitor 1, and factor XIII; human lymphocyte antigen (HLA-G); detoxification enzymes (glutathione- S-transferase M1); cytokines such as interleukin (IL) -1 and IL-6; hormones (CYP17); vasodilators (nitric oxide synthase 3); and vitamins (transcobalamin) are involved in the pathogenesis of sporadic and recurrent miscarriage. It is likely that a gene polymorphism or mutation susceptible to reproductive failure has a beneficial effect on the process of human reproduction with or without the environmental interaction. The factor V Leiden mutation has genetic advantages that are believed to be an improved implantation rate in in vitro fertilization and a reduction of maternal intrapartum blood loss. It has also been demonstrated that the CYP17 A2 allele has bidirectional effects on human reproduction, including increases in susceptibility to recurrent miscarriage and fetal growth enhancement.

There is a lack of well-designed epidemiological studies of possible risk factors for repeated miscarriage. In this Swedish population-based case-control study, we investigated the association between sociodemographic and anthropometric factors, obstetric history and life-style factors, with respect to the risks of first-trimester repeated miscarriage. Information on maternal characteristics was collected through in-person interviews. Plasma blood samples were analysed for cotinine and folate concentrations. Adjusted odds ratios (OR) with 95% confidence interval [CI] were used to estimate the relative risk of repeated miscarriage. The risks of repeated miscarriage were increased for women aged > or = 35 years (adjusted OR 2.9 [95% CI 1.4, 5.8]), as well as for women aged < or = 24 years (OR 2.8 [95% CI 1.1, 6.8]). Women with a history of at least one preceding miscarriage prior to the two index pregnancies, women reporting prolonged time to conceive, and women with a history of myoma, faced a more than fourfold increased risk of repeated miscarriage. Smokers were at an increased risk of repeated miscarriage (OR 2.1 [95% CI 1.1, 4.1]). Among non-smoking women with high caffeine intake, there was an increased risk of repeated miscarriage, whereas there was no such association among smokers. Low plasma folate levels were not associated with increased risks.

Trefoil factor 3 (TFF3) gene is an inflammatory mediator expressed in human endometrium during the window of implantation. The aim of this study was to evaluate the possible genetic association of TFF3 variants in recurrent spontaneous abortion. Women with a history of recurrent spontaneous abortion (n = 164) and healthy pregnant women (n = 143) were genotyped for five TFF3 polymorphisms (rs225439 G/A, rs533093 C/T, rs225361 A/G, rs11701143 T/C and rs77436142 G/C). In addition, haplotypes formed within the gene were analysed. Within the recurrent spontaneous abortion group, women who at some point had given birth and childless women had 4.19 ± 1.75 and 5.34 ± 3.42 consecutive spontaneous abortions, respectively. Women who had experience recurrent spontaneous abortions had a lower allele frequency of the rs11701143 promoter region minor C allele compared with fertile women (0.02 versus 0.05, P = 0.015). Patients with rs225361 AG genotype had significantly more successful pregnancies before spontaneous abortion than those with homozygous AA and GG genotypes (P = 0.014). No significant differences in haplotype frequencies between patients and controls were detected. Possible genetic risk factors identified that might contribute to the pathogenesis of idiopathic recurrent spontaneous abortion were TFF3 gene variants. Copyright © 2014. Published by Elsevier Ltd.

Treatment of Adults with Idiopathic Recurrent Pericarditis: Novel Use of Immunotherapy.

Schwier, Nicholas C; Hale, Genevieve M; Davies, Marie L

2017-03-01

Idiopathic recurrent pericarditis (IRP) can be challenging to treat. Even after guideline-directed first-line treatment consisting of aspirin (ASA) or a nonsteroidal antiinflammatory drug (NSAID) in combination with colchicine therapy, recurrences still occur in greater than 20% of patients. Many patients then require treatment with long-term corticosteroids, which is not a favorable option due to their short- and long-term adverse effects. Because it is theorized that the pathophysiology of IRP may possess autoimmune sequelae, the use of immunotherapy for the treatment of IRP has emerged. In this review, we describe the literature associated with immunotherapy used to treat IRP in an adult population as well as provide an overview of the safety and monitoring parameters for each agent. The most common immunotherapies used after patients have had multiple recurrences of IRP are anakinra, intravenous immunoglobulin (IVIG), and azathioprine. In most cases, these immunotherapies are adjunctive therapy, with the goal of tapering and discontinuing immunosuppressive corticosteroids. After reviewing the data, anakinra resulted in more patients discontinuing corticosteroids and prevented further recurrences of pericarditis. IVIG resulted in symptom resolution and no further recurrences in most of the patients. Azathioprine was associated with more than half of patients becoming recurrence free; however, many patients required a restart of corticosteroids due to recurrence. Clinicians should be aware of the adverse effects of immunotherapy, ranging from mild gastrointestinal events to risk of infection and serious blood dyscrasias that may require diligent monitoring. The use of immunotherapy for the treatment of adults with IRP should be restricted to patients who have multiple recurrences. Ideally, immunotherapy would be adjunctive to first-line combination therapy with ASA/NSAID plus colchicine, with the goal of tapering and discontinuing immunosuppressive

Bacterial vaginosis (BV) is related to the increased risk of miscarriage, preterm labor, and postpartum endometritis. The aim of this study was to evaluate the association between BV and the history of spontaneous abortion and recurrent pregnancy losses. We also examined periods of gestation, including the first and second trimester miscarriages. The study population consisted of 200 fertile women. Sixty one (30.5%) of 200 women had the history of a spontaneous abortion in the last six months ( N = 30) and at least three recurrent pregnancy losses ( N = 31). BV was diagnosed either by using Papanicolaou staining, Gram staining, or by culturing with BV-associated bacteria, Gardnerella vaginalis . The presence of BV was statistically associated with the history of a spontaneous abortion in the last 6 months ( P < 0.05), whereas there was no significant relationship between BV and recurrent pregnancy losses ( P > 0.05). These women were also evaluated in view of periods of gestation. Forty-seven (77%) of 61 women had first trimester miscarriage (≤12 weeks) and 14 (23%) of 61 women had second trimester miscarriage (>12 weeks). There was a statistically significant relationship between BV and second trimester miscarriage ( P < 0.05). Positive BV findings were not associated with discharge, itching, and pain ( P > 0.05). BV may contribute to spontaneous abortion and second trimester miscarriage.

Nephrolithiasis is a frequent condition. While it is generally accepted that such condition carries a risk of recurrence over time, the exact risk and its predictors have been rarely quantitated. We aimed to estimate recurrence of kidney stones, overall and in specific subgroups, from randomized controlled trials (RCTs) of calcium stone formers. Systematic review of RCTs of adult patients with idiopathic calcium kidney stones. Recurrence rates analyzed in subgroups based on type of intervention and other characteristics, using Poisson regression models. The analysis included 21 RCTs with 2168 participants over a median follow-up of 3.2 years (range 0.5-9.7). The median recurrence of kidney stones was 15 per 100 person-years (range 0-110). Recurrence was higher in those with two or more previous stone episodes compared to those with a single episode at enrolment (16 vs. 6 per 100 person-years, p < 0.001) and in those untreated or treated with dietary changes compared to those treated with drugs (26 vs. 23 vs. 9 per 100 person-years, p < 0.001). The effect of drugs on recurrence seemed to be beneficial only among those with two or more previous stone episodes. The overall recurrence rate of stones depends on factors such as previous stone history and type of treatment. Dietary approaches seem to be more effective among single stone formers, whereas drugs seem to be more effective among recurrent stone formers.

Recurrent pregnancy loss: evaluation and treatment.

Recurrent pregnancy loss (RPL) is a multifactorial condition. Approximately half of patients with RPL will have no explanation for their miscarriages. De novo chromosome abnormalities are common in sporadic and recurrent pregnancy loss. Testing for embryonic abnormalities can provide an explanation for the miscarriage in many cases and prognostic information. Regardless of the cause of RPL, patients should be reassured that the prognosis for live birth with an evidence-based approach is excellent for most patients. The authors review current evidence for the evaluation and treatment of RPL and explore the proposed use of newer technology for patients with RPL. Copyright © 2015 Elsevier Inc.

Miscarriage experiences of lesbian couples.

PubMed

Wojnar, Danuta

2007-01-01

This was a descriptive phenomenological study of 10 self-identified lesbian couples who had experienced miscarriage in the context of a committed relationship. Analysis of individual and joint open-ended interviews revealed that the experience of miscarriage for lesbian couples must be viewed from the perspective of the difficulties surrounding conception as well as the actual pregnancy loss. The overarching theme, "We are not in control," captures the struggles lesbian couples faced in conceiving their pregnancies and the sense of loss that accompanied miscarrying. These experiences constituted two sub-themes: "We work so hard to get a baby" and "It hurts so bad: The sorrow of miscarriage." Our results indicate that the experience of miscarriage is compounded by the complexities of planning and achieving pregnancy. Practitioners need to be aware of the unique perspectives lesbian couples have on pregnancy and miscarriage and remain sensitive to their unique needs. Findings may serve as an intervention framework for nurse midwives and others caring for lesbian couples after miscarriage.

Recurrent pericarditis is one of the most frequent pericardial diseases, affecting up to 30% of the patients who have experienced acute pericarditis. While the diagnosis of acute pericarditis is sometime straight forward, its etiology and therapeutic management are still a challenge for physicians. In developed countries, the idiopathic form is the most frequent, and the search for an infectious etiology is almost invariably negative. Nevertheless, since standard treatment with nonsteroidal anti-inflammatory drugs and colchicine is not always able to neutralize pericardial inflammation in recurrent pericarditis, anakinra, an IL-1 receptor antagonist, has been proposed as a possible therapeutic alternative for refractory forms. IL-1 is a cytokine that exerts a pivotal role in innate immunity and in the pathogenesis of some autoimmune diseases, such as rheumatoid arthritis, and in autoinflammatory disorders, as familial Mediterranean fever and cryopyrin-associated periodic syndromes. The successful management of patients with acute idiopathic recurrent pericarditis (IRP) needs a teamwork approach, where cardiologists, rheumatologists, clinical immunologists and internists are involved. In this review, we will discuss the clinical and therapeutical challenges of IRP both in adults and children from a clinical practice standpoint. We will also briefly illustrate the main pathogenic mechanisms of IRP to provide internists and cardiologists with the rationale for approaching the use of anakinra in selected clinical cases.

Since the first study was published reporting the candidate association between the prolactin receptor gene intron C/T polymorphism (rs37389) and recurrent miscarriage, no replication study has been performed. In this study, we investigated the role of the prolactin receptor gene C/T polymorphism in 311 Korean women with recurrent pregnancy loss and 314 controls. Genotyping for prolactin receptor gene intron C/T polymorphism was performed using a TaqMan assay. The significance of difference in the genotype distribution was assessed using a chi-square test, and continuous variables were compared using a Student's t-test. The genotype distribution of the prolactin receptor gene C/T polymorphism in the recurrent pregnancy loss group did not differ from that in the control group (CC/CT/TT rates were 49.8%/41.5%/8.7% and 52.5%/37.6%/9.9% for the recurrent pregnancy loss patient and control groups, respectively, p = .587). When the analysis was restricted to patients with three or more consecutive spontaneous miscarriages or patients without prior live birth, there were also no differences in the genotype distribution between these subgroups and controls. In conclusion, the findings of the current study suggest that the prolactin receptor gene intron C/T polymorphism is not a major determinant of the development of recurrent pregnancy loss. Impact statement What is already known: Many studies have investigated whether there is a genetic component for the risk of recurrent pregnancy loss. Recently, one study investigated whether genetic polymorphisms involved in the regulation of the hypothalamic-pituitary-ovarian axis would be associated with recurrent miscarriage. Among 35 polymorphisms in 20 candidate genes, genotype distribution with regard to the prolactin receptor gene intron C/T polymorphism (rs37389) differed between the recurrent miscarriage and the control groups.

Exome sequencing can identify genetic causes of idiopathic recurrent pregnancy loss (RPL). We identified compound heterozygous deleterious mutations affecting DYNC2H1 and ALOX15 in two out of four families with RPL. Both genes have a role in early development. Bioinformatics analysis of all genes with rare and putatively pathogenic mutations in miscarriages and couples showed enrichment in pathways relevant to pregnancy loss, including the complement and coagulation cascades pathways. Next generation sequencing (NGS) is increasingly being used to identify known and novel gene mutations in children with developmental delay and in fetuses with ultrasound-detected anomalies. In contrast, NGS is rarely used to study pregnancy loss. Chromosome microarray analysis detects putatively causative DNA copy number variants (CNVs) in ∼2% of miscarriages and CNVs of unknown significance (predominantly parental in origin) in up to 40% of miscarriages. Therefore, a large number of miscarriages still have an unknown cause. Whole exome sequencing (WES) was performed using Illumina HiSeq 2000 platform on seven euploid miscarriages from four families with RPL. Golden Helix SVS v8.1.5 was used for data assessment and inheritance analysis for deleterious DNA variants predicted to severely disrupt protein-coding genes by introducing a frameshift, loss of the stop codon, gain of the stop codon, changes in splicing or the initial codon. Webgestalt (http://bioinfo.vanderbilt.edu/webgestalt/) was used for pathway and disease association enrichment analysis of a gene pool containing putatively pathogenic variants in miscarriages and couples in comparison to control gene pools.

BACKGROUND Miscarriage is the spontaneous loss of a pregnancy before 12 weeks (early miscarriage) or from 12 to 24 weeks (late miscarriage) of gestation. Miscarriage occurs in one in five pregnancies and can have considerable physiological and psychological implications for the patient. It is also associated with significant health care costs. There is evidence that potentially preventable infections may account for up to 15% of early miscarriages and up to 66% of late miscarriages. However, the provision of associated screening and management algorithms is inconsistent for newly pregnant women. Here, we review recent population-based studies on infections that have been shown to be associated with miscarriage. METHODS Our aim was to examine where the current scientific focus lies with regards to the role of infection in miscarriage. Papers dating from June 2009 with key words ‘miscarriage’ and ‘infection’ or ‘infections’ were identified in PubMed (292 and 327 papers, respectively, on 2 June 2014). Relevant human studies (meta-analyses, case–control studies, cohort studies or case series) were included. Single case reports were excluded. The studies were scored based on the Newcastle – Ottawa Quality Assessment Scale. RESULTS The association of systemic infections with malaria, brucellosis, cytomegalovirus and human immunodeficiency virus, dengue fever, influenza virus and of vaginal infection with bacterial vaginosis, with increased risk of miscarriage has been demonstrated. Q fever, adeno-associated virus, Bocavirus, Hepatitis C and Mycoplasma genitalium infections do not appear to affect pregnancy outcome. The effects of Chlamydia trachomatis, Toxoplasma gondii, human papillomavirus, herpes simplex virus, parvovirus B19, Hepatitis B and polyomavirus BK infections remain controversial, as some studies indicate increased miscarriage risk and others show no increased risk. The latest data on rubella and syphilis indicate increased antenatal

This article discusses the current trends in the diagnosis and treatment of recurrent pregnancy loss. Genetic testing of the miscarriage tissue by 23-chromosome microarray and the ability to identify maternal cell contamination have increased our awareness of the role of aneuploidy as a cause of recurrent pregnancy loss. This increasing influence and the role of genetic testing in developing a strategy for the evaluation of recurrent pregnancy loss are described and discussed. The most common questions that practicing physicians ask about recurrent pregnancy loss include how many losses are needed to make the diagnosis, what counts as a pregnancy loss, what constitutes a full workup, should we get karyotypes on the parents and the miscarriage, and what is the prognosis for a live birth? This review attempts to answer those questions based on current research and clinical experience to expand our current understanding of recurrent pregnancy loss.

The Therapeutic Role of Interleukin-1 Inhibition in Idiopathic Recurrent Pericarditis: Current Evidence and Future Challenges

Recurrent pericarditis is a common complication of acute pericarditis (15–30%) for which, in most cases, no underlying etiology is found [idiopathic recurrent pericarditis (IRP)]. IRP is currently viewed as an autoinflammatory disease with characteristic recurrent episodes of sterile inflammation. According to the most recent Guidelines, the initial treatment regimen consists of a combination of aspirin or non-steroidal anti-inflammatory drugs with colchicine followed by the addition of corticosteroids in resistant or intolerant cases. Despite this treatment approach, a number of patients either do not respond or cannot tolerate the above therapies. For this refractory group, small case series and a recent randomized controlled trial have shown that interleukin-1 inhibition with anakinra is a rapidly acting, highly efficient, steroid-sparing, and safe therapeutic intervention. In this perspective, we discuss the available clinical evidence and our own clinical experience as well as the future prospects of this novel therapeutic approach for patients with IRP.

Of the 1,222 samples analyzed, 592 had numeric chromosomal abnormalities, and 630 were normal 46,XX or 46,XY (456 and 187, respectively). In 269 of the 46,XX specimens, MCC with no embryonic component was found. With the exclusion of maternal 46,XX results, the chromosomal abnormality rate increased from 48% to 62%, and the ratio for XX to XY results dropped from 2.6 to 1.0. Over half of the normal 46,XX results in miscarriage specimens were due to MCC. The use of SNPs in MCC testing allows for precise identification of chromosomal abnormalities in miscarriage as well as MCC, improving the accuracy of products of conception testing.

Hyperhomocysteinemia and methylenetetrahydrofolate reductase (MTHFR) gene mutation have been postulated as a possible cause of recurrent miscarriage (RM). There is a wide variation in the prevalence of MTHFR polymorphisms and homocysteine (Hcy) plasma levels among populations around the world. The present study was undertaken to investigate the possible association between hyperhomocysteinemia and its causative genetic or acquired factors and RM in Catalonia, a Mediterranean region in Spain. Sixty consecutive patients with ≥ 3 unexplained RM and 30 healthy control women having at least one child but no previous miscarriage were included. Plasma Hcy levels, MTHFR gene mutation, red blood cell (RBC) folate and vitamin B12 serum levels were measured in all subjects. No significant differences were observed neither in plasma Hcy levels, RBC folate and vitamin B12 serum levels nor in the prevalence of homozygous and heterozygous MTHFR gene mutation between the two groups studied. In the present study RM is not associated with hyperhomocysteinemia, and/or the MTHFR gene mutation.

It is known that sperm samples from recurrent pregnancy loss (RPL) couples have an increase in their sperm DNA fragmentation (SDF), but no studies have been performed in order to identify differences between single stranded SDF (ssSDF) and double stranded SDF (dsSDF) in these patients. This could be relevant because the type of DNA damage could have different effects. Semen samples were classified attending their clinical status: 25 fertile donors and 20 RPL patients with at least two unexplained first trimester miscarriages. SDF was analysed using alkaline and neutral Comet assay, SCD test and pulsed-field gel electrophoresis (PFGE), and ROC analysis including data from 105 more infertile patients (n = 150) was performed to establish predictive threshold values. SDF for alkaline and neutral Comet, and the SCD test was analysed in these categories of individuals. Data revealed the presence of two subgroups within fertile donors. The values obtained were 21.10±9.13, 23.35±10.45 and 12.31±4.31, respectively, for fertile donors with low values for both ssSDF and dsSDF; 27.86±12.64, 80.69±12.67 and 12.43±5.22, for fertile donors with low ssSDF and high dsSDF; and 33.61±15.50, 84.64±11.28 and 19.28±6.05, for unexplained RPL patients, also showing a low ssSDF and high dsSDF profile. This latter profile was seen in 85% of unexplained RPL and 33% of fertile donors, suggesting that it may be associated to a male risk factor for undergoing RPL. ROC analysis regarding recurrent miscarriage set the cut-off value at 77.50% of dsDNA SDF. PFGE for low ssSDF and high dsSDF profile samples and positive controls treated with DNase, to induce dsDNA breaks, showed a more intense band of about 48 kb, which fits the toroid model of DNA compaction in sperm, pointing out that some nuclease activity may be affecting their sperm DNA in RPL patients. This work identifies a very specific SDF profile related to the paternal risk of having RPL. PMID:23028579

In spontaneous pregnancies, endometriosis appears to be a risk factor of miscarriage. The aim of this study is to evaluate the association between endometriosis and miscarriage in spontaneous pregnancy. We searched the Cochrane Library, Medline of eligible studies from inception to December 2016, without any restriction. We selected studies that compared endometriosis-affected pregnant women to disease-free pregnant women. To ensure the quality of the methodology, the PRISMA criteria have been met at all stages of the development of this meta-analysis. The primary adverse pregnancy outcomes studied was miscarriage. Three reviewers independently extracted the studies' characteristics and outcome data. Of 225 identified abstracts, 4 primary studies met our inclusion criteria by comparing spontaneous pregnant patients with endometriosis to disease-free women. Miscarriage rate was higher in the endometriosis group (OR 1.77 [CI 95% 1.13-2.78]). In spontaneous pregnancies, endometriosis appears to be a risk factor of miscarriages (almost 80% increased risk). Further prospective studies are needed to confirm these results in order to establish the exact impact of endometriosis on spontaneous pregnancy course. Copyright © 2017 Elsevier Masson SAS.

The aetiology of spontaneous miscarriage, the most common pregnancy complication, remains undefined. One of postulated factors involved in miscarriage pathology is interleukin 6 (IL-6). Therefore, the aim of the study was to evaluate IL-6 and interleukin 6 receptor (IL-6R) gene polymorphisms in patients with spontaneous miscarriage. One hundred fifty-seven patients diagnosed with spontaneous miscarriage and age and gestational time matched controls were included in the case-control study. In all study participants circulating IL-6 levels (chemiluminescent immunoassay) and IL6-174G>C as well as IL6R rs2228145:A>C polymorphisms were evaluated. The distribution of IL6 as well as IL6R alleles and genotypes were similar in the controls and patients with miscarriage. Only a trend of more frequent appearance of -174GC+CC and C allele in the patients with miscarriage was noted. Blood serum concentrations of IL-6 were significantly elevated in patients with miscarriage vs those with physiological pregnancy. Likewise, IL-6 concentrations differ significantly with the types of miscarriage. The highest concentrations of the cytokine was seen in subjects with incomplete miscarriage (4.28 ± 4.88 pg/ml) followed by imminent miscarriage (2.97 ± 2.42 pg/ml), and then missed miscarriage (2.07 ± 1.90 pg/ml), being significantly the lowest in missed miscarriage group. No association between the IL6 genotype and IL-6 serum concentration were noted, both in the miscarriage group and in the control group. The findings of the study support the role of IL-6 in spontaneous miscarriage irrespectively of its type. However, no correlation between circulating IL-6 and IL6 gene polymorphism, as well as IL-6 and IL-6R polymorphisms associations with spontaneous miscarriage were revealed. © 2013 John Wiley & Sons A/S.

To investigate prepregnancy cardiovascular function and risk factors in women with previous pregnancy complications. Thirty-four women with previous normal pregnancy (controls), 26 with unexplained recurrent miscarriage (RM) and 14 with pre-eclampsia (PE) and/or intrauterine growth restriction (IUGR), planning to conceive were recruited. Brachial and central blood pressures (BP), cardiac output (CO), peripheral vascular resistance (PVR), aortic stiffness, blood biochemistry and platelet aggregation were assessed. Women with previous PE/IUGR had higher brachial diastolic BP (78 ± 9 vs 71 ± 7 mmHg; p = 0.03), central systolic BP (107 ± 10 vs 99 ± 8 mmHg; p = 0.03), mean arterial pressure (92 ± 10 vs 84 ± 8 mmHg; p = 0.01) and PVR (1499 ± 300 vs 1250 ± 220 dynes.s(-1) cm(-5); p = 0.005), than the controls. No differences were observed in either cardiovascular function or blood biochemistry in women with unexplained RM compared with the controls. Women with previous PE/IUGR though not with RM had a stronger family history of cardiovascular disease (CVD) than controls. Women with previous PE and/or IUGR had higher BP and PVR compared with controls, which may predispose them to CVD later in life. However, in the absence of underlying vascular pathology, women with unexplained RM did not have abnormal cardiovascular function. Prepregnancy period provides an opportunity to identify cardiovascular risks in relation to previous obstetric history.

Our recent paper, based on a pilot cohort of 119 women, showed that serum progesterone <35 nmol/L was prognostic of spontaneous miscarriage by 16 weeks in women with threatened miscarriage in early pregnancy. Using a larger cohort of women from the same setting (validation cohort), we aim to assess the validity of serum progesterone <35 nmol/L with the outcome of spontaneous miscarriage by 16 weeks. In a prospective cohort study, 360 pregnant women presenting with threatened miscarriage between gestation weeks 6-10 at a tertiary hospital emergency unit for women in Singapore were recruited for this study. The main outcome measure measured is spontaneous miscarriage prior to week 16 of gestation. Area under the ROC curve (AUC) and test characteristics (sensitivity, specificity, positive and negative predictive value) at a serum progesterone cutpoint of <35 nmol/L for predicting high and low risk of spontaneous miscarriage by 16 weeks were compared between the Pilot and Validation cohorts. Test characteristics and AUC values using serum progesterone <35 nmol/L in the validation cohort were not significantly different from those in the Pilot cohort, demonstrating excellent accuracy and reproducibility of the proposed serum progesterone cut-off level. The cut-off value for serum progesterone (35 nmol/L) demonstrated clinical relevance and allow clinicians to stratify patients into high and low risk groups for spontaneous miscarriage.

Cosmic radiation and circadian disruption are potential reproductive hazards for flight attendants. Flight attendants from 3 US airlines in 3 cities were interviewed for pregnancy histories and lifestyle, medical, and occupational covariates. We assessed cosmic radiation and circadian disruption from company records of 2 million individual flights. Using Cox regression models, we compared respondents (1) by levels of flight exposures and (2) to teachers from the same cities, to evaluate whether these exposures were associated with miscarriage. Of 2654 women interviewed (2273 flight attendants and 381 teachers), 958 pregnancies among 764 women met study criteria. A hypothetical pregnant flight attendant with median first-trimester exposures flew 130 hours in 53 flight segments, crossed 34 time zones, and flew 15 hours during her home-base sleep hours (10 pm-8 am), incurring 0.13 mGy absorbed dose (0.36 mSv effective dose) of cosmic radiation. About 2% of flight attendant pregnancies were likely exposed to a solar particle event, but doses varied widely. Analyses suggested that cosmic radiation exposure of 0.1 mGy or more may be associated with increased risk of miscarriage in weeks 9-13 (odds ratio = 1.7 [95% confidence interval = 0.95-3.2]). Risk of a first-trimester miscarriage with 15 hours or more of flying during home-base sleep hours was increased (1.5 [1.1-2.2]), as was risk with high physical job demands (2.5 [1.5-4.2]). Miscarriage risk was not increased among flight attendants compared with teachers. Miscarriage was associated with flight attendant work during sleep hours and high physical job demands and may be associated with cosmic radiation exposure.

Recurrences of Bell's palsy.

Bell's palsy in known as the most common cause of facial paralysis, determined by the acute onset of lower motor neuron weakness of the facial nerve with no detectable cause. With a lifetime risk of 1 in 60 and an annual incidence of 11-40/100,000 population, the condition resolves completely in around 71% of the untreated cases. Clinical trials performed for Bell's palsy have reported some recurrences, ipsilateral or contralateral to the side affected in the primary episode of facial palsy. Only few data are found in the literature. Melkersson-Rosenthal is a rare neuromucocutaneous syndrome characterized by recurrent facial paralysis, fissured tongue (lingua plicata), orofacial edema. We attempted to analyze some clinical and epidemiologic aspects of recurrent idiopathic palsy, and to develop relevant correlations between the existing data in literature and those obtained in this study. This is a retrospective study carried out on a 10-years period for adults and a five-year period for children. A number of 185 patients aged between 4 and 70 years old were analyzed. 136 of them were adults and 49 were children. 22 of 185 patients with Bell's palsy (12%) had a recurrent partial or complete facial paralysis with one to six episodes of palsy. From this group of 22 cases, 5 patients were diagnosed with Melkersson-Rosenthal syndrome. The patients' age was between 4 and 70 years old, with a medium age of 27,6 years. In the group studied, fifteen patients, meaning 68%, were women and seven were men. The majority of patients in our group with more than two facial palsy episodes had at least one episode on the contralateral side. Our study found a significant incidence of recurrences of idiopathic facial palsy. Recurrent idiopathic facial palsy and Melkersson-Rosenthal syndrome is diagnosed more often in young females. Recurrence is more likely to occur in the first two years from the onset, which leads to the conclusion that we should have a follow up of patients

We investigated whether mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene and cationic trypsinogen gene are associated with recurrent acute, or chronic idiopathic pancreatitis. Twenty patients with idiopathic pancreatitis (11 women, nine men; mean age, 30 yr) were studied for the presence of a CFTR mutation by screening the genomic DNA for more than 30 mutations and variants in the CFTR gene. Selected mutations of the cationic trypsinogen gene were screened by Afl III restriction digestion or by a mutation-specific polymerase chain reaction (PCR). In each patient exons 1, 2, and 3 of the cationic trypsinogen gene were sequenced. Patients with a CFTR mutation underwent evaluation of further functional electrophysiological test (intestinal current measurement). No mutation of the cationic trypsinogen gene was detected. A CFTR mutation was detected in 6/20 (30.0%) patients. Three patients (15.0%) had a cystic fibrosis (CF) mutation on one chromosome (deltaF508, I336K, Y1092X), which is known to cause phenotypical severe cystic fibrosis. One patient was heterozygous for the 5T allele. In addition, two possibly predisposing CFTR variants (R75Q, 1716G-->A) were detected on four patients, one of these being a compound heterozygous for the missense mutation I336K and R75Q. No other family member (maternal I336K; paternal R75Q; sister I1336K) developed pancreatitis. An intestinal current measurement in rectum samples of patients with a CFTR mutation revealed no CF-typical constellations. CFTR mutations are associated with recurrent acute, or chronic idiopathic pancreatitis, whereas mutations of the cationic trypsinogen mutation do not appear to be a frequent pathogenetic factor.

Cultural consequences of miscarriages of justice.

PubMed

Cole, Simon A

2009-01-01

Social science scholarship has tended to focus more on the causes than the consequences of miscarriages of justice. Within the literature on consequences, the overwhelming emphasis has been on individual consequences: psychological and material impacts on the wrongly convicted individual and, in some cases, other indirectly impacted individuals such as family members of the wrongly convicted and victims of the true perpetrator's future crimes. Some attention has been devoted to social harms, the impact of miscarriages of justice on the broader society within which they are situated, such as the undermining of the legitimacy of the criminal justice system. This paper focuses on what are called here cultural consequences of miscarriages of justice: the way in which some high-profile miscarriages of justice can shape the public's beliefs about some of the most basic "facts" about crime, such as the nature, prevalence, or even existence of certain categories of crime and the types of individual who tend to perpetrate particular types of crime. In this way, the paper argues, miscarriages of justice may have hitherto underexplored consequences: reshaping, based on false premises, the public's belief about the very nature of crime itself. This paper discusses three cases studies of miscarriages of justice that for varying periods of time created widespread false beliefs about the nature of crime in large segments of the public. The paper concludes by noting that the "righting" of these false beliefs was in most cases fortuitous. This suggests that unexposed miscarriages of justice may still be shaping popular beliefs about the nature of crime, and aspects of the public's current conception of crime may yet be based on false premises.

Miscarriage is a common complication of pregnancy that can be caused by a wide range of factors. Poor dietary intake of vitamins has been associated with an increased risk of miscarriage, therefore supplementing women with vitamins either prior to or in early pregnancy may help prevent miscarriage. The objectives of this review are to determine the effectiveness and safety of any vitamin supplementation, on the risk of spontaneous miscarriage, maternal adverse outcomes and fetal and infant adverse outcomes. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (21 June 2010). All randomised and quasi-randomised trials comparing one or more vitamins with either placebo, other vitamins, no vitamins or other interventions, prior to conception, periconceptionally or in early pregnancy (less than 20 weeks' gestation). At least two review authors independently assessed trials for inclusion, extracted data and assessed trial quality. We identified 28 trials assessing supplementation with any vitamin(s) starting prior to 20 weeks' gestation and reporting at least one primary outcome that was eligible for the review. Overall, the included trials involved 96,674 women and 98,267 pregnancies. Three trials were cluster randomised and combined contributed data for 62,669 women and 64,210 pregnancies in total. No significant differences were seen between women taking any vitamins compared with controls for total fetal loss (relative risk (RR) 1.04, 95% confidence interval (CI) 0.95 to 1.14), early or late miscarriage (RR 1.09, 95% CI 0.95 to 1.25) or stillbirth (RR 0.86, 95% CI 0.65 to 1.13) and most of the other primary outcomes, using fixed-effect models. Compared with controls, women given any type of vitamin(s) pre or peri-conception were more likely to have a multiple pregnancy (RR 1.38, 95% CI 1.12 to 1.70, three trials, 20,986 women). Taking any vitamin supplements prior to pregnancy or in early pregnancy does not prevent women experiencing miscarriage

Recurrent pregnancy loss is newly defined as more than two consecutive miscarriages. Recurrent pregnancy loss occurs in <5% of total pregnancies. The cause in approximately 40-60% of recurrent pregnancy loss cases remains elusive and must be determined. We investigated two unrelated Iranian consanguineous families with recurrent pregnancy loss. We performed exome sequencing using DNA from a miscarriage tissue and identified a homozygous NOP14 missense variant (c.[136C>G];[136C>G]) in both families. NOP14 is an evolutionally conserved protein among eukaryotes and is required for 18S rRNA processing and 40S ribosome biogenesis. Interestingly, in zebrafish, homozygous mutation of nop14 (possibly loss of function) resulting from retrovirus-mediated insertional mutagenesis led to embryonic lethality at 5 days after fertilization, mimicking early pregnancy loss in humans. Similarly, it is known that the nop14-null yeast is inviable. These data suggest that the homozygous NOP14 mutation is likely to cause recurrent pregnancy loss. Furthermore, this study shows that exome sequencing is very useful to determine the etiology of unsolved recurrent pregnancy loss.

The liver X receptors (LXRs) have been shown to be crucially involved in maternal-fetal cholesterol transport and placentation. The aim of this study was to investigate the expression pattern and frequency of LXR under normal physiological circumstances and in spontaneous abortion and/or recurrent miscarriage. A total of 29 (12 physiologic pregnancies/10 spontaneous abortions/7 recurrent miscarriages) human pregnancies in first trimester were analysed for LXR expression. Expression changes were evaluated by immunohistochemistry for receptor and quantitative RT-PCR (TaqMan) was performed to determine the level of LXR mRNA expression. We also stained for RXRα and PPARγ as possible heterodimers of LXR. LXR expression was downregulated in the syncytiotrophoblast of spontaneous abortion placentas compared to normal pregnancy. In recurrent miscarriage there was a trend for a downregulation. Decidua showed an even stronger downregulation in both groups. In the syncytiotrophoblast we found a positive correlation for the combination of LXR/PPARγ in abortions and a negative correlation for LXR/RXRα. In addition, double-immunofluorescence staining showed that LXR as well as RXRα and PPARγ are expressed by the extravillous trophoblast. Finally, RXRα and LXR showed coexpression in the same extravillous trophoblast cells. To conclude, our data show that LXR expression is decreased in miscarriage. PMID:23690759

This study aimed to evaluate the efficacy of PLI and results of subsequent pregnancy in women with RM showing alloimmune response. Immunological investigations were performed in patients with RM. Subsequently, PLI was administered to 241 patients at their request. Of these, 202 conceived between September 2005 and September 2012. Of the 202 women, 169 pregnancies resulted in term delivery; the remaining 33 resulted in subsequent miscarriages (success rate = 83.7%). During seven-years observations of 202 tested individuals, 114 women were pregnant again for the second time and 92 pregnancies of them resulted in the next term delivery (success rate =80.7%). Alloimmune background indicated that PLI might improve pregnancy outcome in patients suffering from RM. Long-term monitoring did not reveal any negative effects of PLI on the immunological system in the treated women or newborn babies.

Is superfertility associated with recurrent pregnancy loss?

PubMed

Orlando, Jennie; Coulam, Carolyn

2014-12-01

A recent hypothesis has implicated superfertility as a cause of recurrent pregnancy loss. Clinical support for the concept comes from one report that 40% of women experiencing recurrent miscarriages had monthly fecundity rates of 60% or greater and thus were designated as superfertile. To confirm or refute this finding, clinical histories of 201 women with a history of recurrent pregnancy loss were reviewed and months to desired pregnancy, karyotypes of their products of conception as well as results of laboratory tests including antiphospholipid antibodies and circulating natural killer cells were recorded. The prevalence of superfertility was 32% (64/201) among recurrently aborting women compared with 3% of the general population according to the model of Tietze (P < 0.0001). Fifty-nine of the 201 (30%) study patients displayed presence of APA,LA, increased CD56(+) cells, or increased NK cytotoxicity and were designated as having an immunologic risk factor. Of the 192 karyotypes of products of conception from women with a history of recurrent miscarriage, 153 (80%) had a normal chromosome complement and 38 (20%) were abnormal. Among the normal karyotypes, 86 (56%) were 46XX and 67 (44%) were 46XY. Recurrent pregnancy loss is associated with superfertility in 32%, immunologic risk factors in 30% and a 20% frequency of chromosomally abnormal pregnancy losses. Thus, implantation failure can result from too much or too little implantation. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To estimate the strength of association between first-trimester bleeding and miscarriage, setting aside bleeding at time of loss. Women enrolled in a community-based pregnancy cohort study before or during early pregnancy. Detailed first-trimester bleeding data were collected by telephone interview. Bleeding episodes proximal to miscarriage (within 4 days) were excluded. We used discrete-time hazard models to evaluate the association between bleeding and miscarriage. Models were adjusted for maternal age, prior miscarriage, and smoking. Exploratory regression tree analysis was used to evaluate the relative importance of other bleeding characteristics (duration, associated pain, color, timing). Of the 4,510 participants, 1,204 (27%) reported some first-trimester vaginal bleeding or spotting, and 517 miscarriages were observed. Eight percent of those with bleeding reported heavy bleeding episodes. When we evaluated any bleeding, including episodes of only spotting, the unadjusted relative odds ratio (OR) of miscarriage for women with bleeding (n=1,204) was 1.1 (95% confidence interval [CI] 0.9-1.3). However, women who reported heavy bleeding (n=97) had nearly three times the risk of miscarriage compared with women without bleeding during the first trimester (OR 3.0, 95% CI 1.9-4.6). Adjustment for covariates had little effect on estimates. Further analyses suggested that women with heavy bleeding accompanied by pain were the group accounting for most of the elevated risk. Heavy bleeding in the first trimester, particularly when accompanied by pain, is associated with higher risk of miscarriage. Spotting and light episodes are not, especially if lasting only 1-2 days.

Serum concentrations of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) were assessed in relation to miscarriage in a population of mid-Ohio River Valley residents highly exposed to PFOA through contaminated drinking water. Serum PFOA and PFOS concentrations were measured in 1129 women in 2005-2006 who reported pregnancy outcomes in follow-up interviews between 2008 and 2011. In the analysis, we included 1438 reported live births, stillbirths, and miscarriages with estimated conception dates after the serum measurements. Preconception serum levels of PFOA and PFOS were analyzed in relation to miscarriage using logistic regression and generalized estimating equations. There was little evidence of association between PFOA and miscarriage. For PFOS, when including all reported prospective pregnancies, the odds ratio of miscarriage per log ng/ml increase was 1.21 (95% confidence interval = 0.94-1.55); in subanalyses restricted to each woman's first pregnancy conceived after the serum measurement, the odds ratio was 1.34 (1.02-1.76). Categorical analyses showed elevated odds ratios for the top 4 quintiles relative to the first quintile, without a monotonic trend. Positive associations between PFOS and miscarriage were strongest among nulligravid pregnancies. In this prospective study of miscarriage in a population exposed to high levels of PFOA and background levels of PFOS, we found little evidence of association with serum levels of PFOA and limited evidence of association with serum levels of PFOS.

The aim of this study was to investigate the potential association of matrix metalloproteinase 7 (MMP7) -181 A/G and MMP12 -82 A/G functional single nucleotide polymorphisms (SNP) with idiopathic recurrent spontaneous abortion (IRSA) in Slovenian reproductive couples. A case-control study was conducted on 149 couples with 3 or more consecutive idiopathic spontaneous pregnancy loses and 149 women and men with at least 2 live births and no history of pregnancy complications. Genotyping of MMP7 -181 A/G and MMP12 -82 A/G SNPs was performed using polymerase chain reaction and restriction fragment length polymorphism methods. There were no statistically significant differences in the distribution of MMP7 -181 A/G and MMP12 -82 A/G genotype, allele, or haplotype frequencies between IRSA patients and controls, as well as patients' primary and secondary IRSA. We also found no association of MMP7 -181 A/G and MMP12 -82 A/G genotypes, alleles, and haplotypes with IRSA. We found no evidence to support the association between IRSA and MMP7 -181 A/G and MMP12 -82 A/G SNPs in Slovenian reproductive couples.

Objective To estimate the strength of association between first-trimester bleeding and miscarriage, setting aside the bleeding at time of loss. Methods Women enrolled in a community-based pregnancy cohort study before or during early pregnancy. Detailed, first-trimester bleeding data were collected by telephone interview. Bleeding episodes proximal to miscarriage (within 4 days) were excluded. We used discrete-time hazard models to evaluate the association between bleeding and miscarriage. Models were adjusted for maternal age, prior miscarriage, and smoking. Exploratory regression tree analysis was used to evaluate the relative importance of other bleeding characteristics (duration, associated pain, color, timing). Results Of the 4510 participants, 1204 (27%) reported some first-trimester vaginal bleeding or spotting, and 517 miscarriages were observed. Eight percent of those with bleeding reported heavy bleeding episodes. When we evaluated any bleeding, including episodes of only spotting, the unadjusted relative odds (OR) of miscarriage for women with bleeding (n=1204) was 1.1 (95% confidence interval [CI] 0.9–1.3). However, women who reported heavy bleeding (n=97)had nearly three times the risk of miscarriage compared to women without bleeding during the first trimester (OR 3.0, 95% CI 1.9–4.6). Adjustment for covariates had little effect on estimates. Further analyses suggested that women with heavy bleeding accompanied by pain were the group accounting for most of the elevated risk. Conclusion Heavy bleeding in the first trimester, particularly when accompanied by pain, is associated with higher risk of miscarriage.

A practical approach to the prevention of miscarriage: part 5--antiphospholipid syndrome as a cause of spontaneous abortion.

PubMed

Check, J H

2011-01-01

To describe the diagnosis and treatment of antiphospholipid syndrome as it relates to spontaneous abortion. The relative importance of performing tests of antiphospholipid antibodies that prolong the partial thromboplastin time and other autoantibodies against phospholipids measured by ELISA are discussed. The most important diagnostic tests are the lupus anticoagulant, anticardiolipin antibody and antiphosphatidyl serine. Low molecular weight heparin and low dose aspirin are the two most important therapies. Women with recurrent miscarriages or even an unexplained miscarriage especially after ten weeks (but sometimes even early first trimester) or a history of thrombosis or intrauterine growth restriction and maybe preeclampsia are candidates for anticoagulant therapy, especially with the presence of significant levels of the lupus anticoagulant or anticardiolipin or antiphosphatidyl serine antibodies (> 40 pl units/ml).

Human leukocyte antigen-G (HLA-G) is a non-classical class I molecule highly expressed by extravillous cytotrophoblast cells. Due to a single base pair deletion, its function can be compensated by other isoforms. Investigating the frequency of null allele in Recurrent Miscarriage (RM) subjects could be useful in understanding the relationship between frequency of this allele and RM in a given population. This study aimed to determine the frequency of HLA-G*0105N null allele and its potential association with down-regulation of HLA-G in subjects with RM. Western blotting was used to assess the level of HLA-G protein expression. For investigating the frequency of HLA-G*0105N null allele in RM subjects, PCR-RFLP method was used. Exon 3 of HLA-G gene was amplified by polymerase chain reaction (PCR). Subsequently, PpuM-1 enzyme was employed to digest the PCR products and fragments were analyzed using gel electrophoresis. Digestion using restriction enzyme showed the presence of heterozygous HLA-G*0105N null allele in 10% of the test population. Western blotting results confirmed the decrease in expression of HLA-G in the placental tissue of subjects with RM compared to subjects who could give normal birth. The frequency of heterozygous HLA-G*0105N null allele was high to some extent in subjects with RM. The mutation rate in subjects suggested that there is a significant association between RM and frequency of mutations in this allele.

To analyze the presence of Y chromosome microdeletions in males of Mexican couples with idiopathic recurrent pregnancy losses (RPL). Seventy-one males from couples with RPL and 66 fertile males as controls were studied. DNA was isolated from peripheral lymphocytes and used to run multiplex polymerase chain reactions. Regions AZFa (sY84, sY86), AZFb (sY127, sY134) and AZFc (sY254, sY255) of the Y chromosome were analyzed according to valid guidelines recommended by the European Academy of Andrology and the European Molecular Genetics Quality Network. Also, the sequence tagged sites (STSs): DYS262 (sY67), DYS220 (sY129), DYF85S1 (sY150), DYF86S1 (sY152) and DYF87S1 (sY153) were included in order to analyze STSs previously reported as deleted. A power analysis to support our simple size was performed. Results show an absence of Y chromosome microdeletions in males of couples with RPL and controls with an acceptable statistical power. The study did not show an association of recurrent pregnancy loss and Y chromosome microdeletions in Mexican male partners. Based on the results, the study of Y chromosome microdeletions in couples with RPL is not considered clinically relevant. © 2012 The Authors.

Miscarriage is a common complication of pregnancy that can be caused by a wide range of factors. Poor dietary intake of vitamins has been associated with an increased risk of miscarriage, therefore supplementing women with vitamins either prior to or in early pregnancy may help prevent miscarriage. The objectives of this review are to determine the effectiveness and safety of any vitamin supplementation, on the risk of spontaneous miscarriage, maternal adverse outcomes and fetal and infant adverse outcomes. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (8 September 2004), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 2, 2003) and MEDLINE (1966 to May 2003), Current Contents (1998 to May 2003) and EMBASE (1980 to May 2003). All randomised and quasi-randomised trials comparing one or more vitamins with either placebo, other vitamins, no vitamins or other interventions, prior to conception, periconceptionally or in early pregnancy (less than 20 weeks' gestation). Two review authors independently assessed trials for inclusion, extracted data and assessed trial quality. We identified seventeen trials assessing supplementation with any vitamin(s) starting prior to 20 weeks' gestation and reporting at least one primary outcome that were eligible for the review. Overall, the included trials involved 35,812 women and 37,353 pregnancies. Two trials were cluster randomised and contributed data for 20,758 women and 22,299 pregnancies in total. No difference was seen between women taking any vitamins compared with controls for total fetal loss (relative risk (RR) 1.05, 95% confidence interval (CI) 0.95 to 1.15), early or late miscarriage (RR 1.08, 95% CI 0.95 to 1.24) or stillbirth (RR 0.85, 95% CI 0.63 to 1.14) and most of the other primary outcomes, using fixed-effect models. For the other primary outcomes, women given any type of vitamin(s) compared with controls were less likely to develop pre-eclampsia (RR 0

Understanding the Experience of Miscarriage in the Emergency Department.

Up to 20% of pregnancies end in miscarriage, which can be a significant life event for women with psychological implications. Because the only preventative measure for a miscarriage is risk factor modification, the treatment focuses on confirming the miscarriage has occurred and medical management of symptoms. Although women experiencing a miscarriage are frequently directed to seek medical care in emergency departments, the patients are often triaged as nonemergent patients unless they are unstable, which exposes women to potentially prolonged wait times. Research about miscarriages and emergency departments predominantly focus on medical management with little understanding of how emergency care shapes the experience of miscarriage for women. Seeking to describe the experiences of women coming to the emergency department for care while having a miscarriage, interpretive phenomenology-a form of qualitative research-guided this study. Eight women were recruited to participate in semi-structured face-to-face interviews of 60 to 90 minutes in length. Data were analyzed using hermeneutics and thematic analysis. Five themes emerged: "Pregnant/Life: Miscarriage/Death"; "Deciding to go to the emergency department: Something's wrong"; "Not an illness: A different kind of trauma"; "Need for acknowledgement"; and "Leaving the emergency department: What now?". Participants believed their losses were not acknowledged but instead dismissed. These experiences, combined with a perceived lack of discharge education and clarity regarding follow-up, created experiences of marginalization. This study describes the experience of miscarrying in emergency departments and provides insights regarding how nursing and physician care may affect patient perceptions of marginalization.

Effects of vitamin D deficiency in pregnancy have been associated with some adverse pregnancy outcomes. The 25-hydroxyvitamin D3-1α-hydroxylase (CYP27B1) is integral to the vitamin D metabolic pathway. The enzyme catalyzes localized conversion of pro-hormone 25-hydroxyvitamin D3 to active 1,25-dihydroxyvitamin D3. Our aim was to investigate the expression of CYP27B1 at the fetal-maternal interface in the first trimester pregnancy and to determine whether CYP27B1 was associated with recurrent miscarriage (RM). Expressions of CYP27B1 mRNA and protein in villi and decidua from 20 women undergoing primary miscarriage, 20 women with RM and 20 women with normal pregnancy were evaluated by western blot, and quantitative real-time PCR. The co-localization of CYP27B1 and certain cytokines including IL-10, IFN-γ, TNF-α, and IL-2 expression were examined using immunohistochemistry and confocal microscopy. Women with RM had a significantly lower expression of CYP27B1 mRNA and protein in villous and decidual tissues compared with the normal pregnant women (P = 0.000 in villus, P = 0.002 in decidua for mRNA; P = 0.036 in villus, P = 0.007 in decidua for protein.). Compared with the normal pregnancy, immunostaining for CYP27B1 was significantly decreased in villous trophoblasts and decidual glandular epithelial cells in RM women. No significant differences in the localization of CYP27B1, IL-10, IFN-γ, TNF-α, and IL-2 expression were identified between the normal pregnant and RM women. Women with RM have a lower level of CYP27B1 expression in chorionic villi and decidua compared with normal pregnant women, suggesting that reduced CYP27B1 expression may be associated with RM. The consistent localization of CYP27B1 and IL-10, IFN-γ, TNF-α, and IL-2 expression in villous and decidual tissues suggests the importance of the local production of 1,25(OH)2D3 at the fetal-maternal interface to regulate cytokine responses.

In majority of couples experiencing recurrent pregnancy loss (RPL), etiology is still unknown. Two genetic factors have been suggested to underlie miscarriage in a subset of patients, namely skewed X chromosome inactivation in females and Y chromosome microdeletions in their partners. In males, microdeletions of the Y chromosome are known to cause spermatogenetic failure and male infertility. The aim of the study was to find out the role of Y chromosome microdeletion in male partners of couples experiencing RPL. University hospital and genetic laboratory. Prospective case-control study. 59 couples with a history of RPL and 20 fertile controls (FC) with no miscarriage were included in the study. The study subjects were divided into male partners of RPL couples with abnormal semen parameters (AS) (n = 8), and couples with normal semen parameters (NS) (n = 51). Fertile controls with normal semen parameters were (FC) (n = 20). Y chromosome microdeletion was performed on 40 male partners of RPL and 20 FC. Chi-square test. P <0.05 were considered statistically significant. 13 of the 40 RPL cases showed deletion in three azoospermia factor loci on the long arm of Y chromosome. The P value was significant with Y chromosome microdeletion in RPL cases as compared to 20 FC where no Y chromosome microdeletion was present. Y chromosome microdeletion may be an important hidden cause of recurrent pregnancy miscarriage and can be offered to couples with the undiagnosed cause of miscarriage.

PPAR expression in placenta tissues regulates proinflammatory cytokine production and preserves the quiescence of the uterus during pregnancy. PPAR-γ regulates inflammatory response during gestation while PPAR-δ and TNFα play a central role at implantation, decidualization and placentation. However, their expression levels affect normal pregnancy and may cause gestational complications and miscarriage. The aim of this report is to investigate the relationship of these molecules with unexplained recurrent miscarriage. The miscarriage group was obtained from 12 women, between the ages of 35 to 42 years, who miscarried during the 1st trimester of gestation and controls consisted of 12 healthy women, between the ages of 27 to 39 years, who had electively terminated their pregnancies, during the 1st trimester of gestation. The abortion material was processed and specimens taken were studied using immunohisto-chemical methods. Specimens were taken from decidua basalis and decidua parietalis. Monoclonal antibodies were used against PPAR-γ (Peroxisome Proliferator Activation Receptor γ), PPAR-δ and TNFα (Tumor Necrosis Factor alpha). The results were statistically analyzed with Mann-Whitney test. Our research identified PPAR-γ expression in decidua basalis and decidua parietalis from control group and decidua basalis from miscarriage group. PPAR-δ expression was also identified in both deciduas from both groups. Statistically, no significant change in PPAR-γ and PPAR-δ expression was observed between recurrent miscarriage group and controls. On the contrary, a statistically significant upregulation of TNFα was identified in both deciduas between miscarriage group and controls (p<0.05). Our evidence did not support a possible role of PPARs expression in recurrent pregnancy loss. However, a potential involvement of TNFα in the syndrome was reported. Further research should be performed due to insufficient bibliographic data.

Common endocrinopathies are a frequent contributor to spontaneous and recurrent miscarriage. Although the diagnostic criteria for luteal phase defect (LPD) is still controversial, treatment of patients with both recurrent pregnancy loss and LPD using progestogen in early pregnancy seems beneficial. For patients who are hypothyroid, thyroid hormone replacement therapy along with careful monitoring in the preconceptual and early pregnancy period is associated with improved outcome. Women with polycystic ovary syndrome (PCOS) have an increased risk of pregnancy loss. Management of PCOS with normalization of weight or metformin seems to reduce the risk of pregnancy loss.

A systematic review of dydrogesterone for the treatment of threatened miscarriage

PubMed Central

2012-01-01

The objective of this systematic review was to assess whether the orally acting progestagen, dydrogesterone lowers the incidence of miscarriage in women with threatened miscarriage. A computerized search was performed in Medline, Embase, and Ovid Medline for original reports with the product name ‘Duphaston’ or ‘dydrogesterone’, and limited to clinical human data. Twenty-one reports of dydrogesterone treatment were identified with 1380 patients. Five randomized trials were identified, including 660 women who fulfilled the criteria for metaanalysis. The number of subsequent miscarriages or continuing pregnancies per randomized woman was compared in women receiving dydrogesterone compared to standard bed rest or placebo intervention. There was a 13% (44/335) miscarriage rate after dydrogesterone administration compared to 24% in control women [odds ratio for miscarriage 0.47, (CI = 0.31–0.7), 11% absolute reduction in the miscarriage rate]. The adverse and side effects were summarized in all 21 reports, and seemed to be minimal. Although all the predictive and confounding factors could not be controlled for, the results of this systematic review show a significant reduction of 47% in the odds for miscarriage when dydrogesterone is compared to standard care indicating a real treatment effect.

This study investigates the occurrence of miscarriages over the reproductive life span of women in a population-based study. A questionnaire was sent in 1994 to a random sample of 3000 Finnish women aged 18 to 44 years (73% response rate). Age-adjusted percentages of women having had miscarriages, and age- and other pregnancy event-adjusted odds ratios were calculated. Fifteen percent had at least 1 miscarriage. Miscarriages were more common in the moderately educated group and among women in health and social occupations, but there was no difference according to urbanism or health. By the age of 40 to 44 years, 90% of the women had been pregnant, and for only half had all pregnancies ended in a birth. The sequence of a miscarriage or miscarriages coming first and a birth or births coming later was more common than vice versa. In this population-based study miscarriages appeared incidental. Further studies on social class distribution might reveal new clues regarding etiology.

Periconceptional folic acid prevents miscarriage in Irish families with neural tube defects.

Miscarriages occur to excess in sibships with neural tube defects (NTDs) and among maternal versus paternal relatives in NTD families. Folic acid prevents most NTDs. Its potential to prevent miscarriages has been controversial. We evaluated the relationship of maternal line and periconceptional folic acid with miscarriage. First cousins in Irish families with NTDs were interviewed about pregnancy outcomes and the health of their offspring. Miscarriages were not more frequent among pregnancies of maternal versus paternal first cousins. Folic acid intake during early pregnancy significantly reduced the risk of miscarriage from 15.7 to 9.6%, for an adjusted odds ratio of 0.37 (95% confidence interval 0.19, 0.72, p = 0.005). Folic acid during pregnancy was associated with a reduction of approximately 60% in miscarriages. Miscarriages are common-one in every eight pregnancies in this study. If incorporated into pre-pregnancy counseling, these results could have significant public health impact.

Data from our trial of periconceptional vitamin supplementation for the prevention of neural tube defects have been analysed to assess the influence of various factors on recurrence rates of neural tube defect. Our data suggest that the risk of recurrence of neural tube defect is influenced by the number of previous neural tube defects, area of residence, immediately prior miscarriage, and interpregnancy interval. None of these factors, however, contributed any significant differential risk between supplemented and unsupplemented mothers. Hence we conclude that the highly significant difference in recurrence rates of neural tube defect between supplemented and unsupplemented mothers was due to vitamin supplementation. PMID:3521496

Although taking supplements that contain 400 microg of folic acid before and during early pregnancy reduces a woman's risk for having a baby with a neural-tube defect (NTD), the effects of such supplements on other pregnancy outcomes remain unclear. We examined whether the use of such supplements affects the occurrence of miscarriage. Participants were women in China who had taken part in a recent folic acid campaign to prevent NTDs and who had registered in this campaign before they became pregnant for the first time. We examined the risk for miscarriage among women who had confirmed pregnancies and who had or had not taken pills containing only 400 microg of folic acid before and during early pregnancy. The overall rate of miscarriage was 9.1% (2155/23806). The rates of miscarriage among women who had and had not taken folic acid pills before and during the first trimester were 9.0% and 9.3%, respectively (risk ratio 0.97 [95% CI 0.84-1.12]). The distributions of gestational age at pregnancy diagnosis and at miscarriage were similar for both groups of women. In this population-based study of a cohort of women whose use of folic acid supplements while pregnant had been previously documented and who had been pregnant for the first time, we found no evidence that daily consumption of 400 microg of folic acid before and during early pregnancy influenced their risk for miscarriage.

Recurrent Idiopathic Catatonia: Implications beyond the Diagnostic and Statistical Manual of Mental Disorders 5th Edition.

We describe a case of recurrent, life-threatening, catatonic stupor, without evidence of any associated medical, toxic or mental disorder. This case provides support for the inclusion of a separate category of "unspecified catatonia" in the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) to be used to classify idiopathic cases, which appears to be consistent with Kahlbaum's concept of catatonia as a distinct disease state. But beyond the limited, cross-sectional, syndromal approach adopted in DSM-5, this case more importantly illustrates the prognostic and therapeutic significance of the longitudinal course of illness in differentiating cases of catatonia, which is better defined in the Wernicke-Kleist-Leonhard classification system. The importance of differentiating cases of catatonia is further supported by the efficacy of antipsychotics in treatment of this case, contrary to conventional guidelines.

To describe the use of complementary approaches in pregnant women with a history of miscarriage and to investigate whether a miscarriage is associated with the use of complementary approaches during their pregnancy. A cross-sectional survey was distributed to pregnant women residing in the United States (N=890). Women who had a history of miscarriage, were Caucasian, were college educated, reported a high income, had low depression scores, and had low anxiety scores (all P<0.001) were more likely to use complementary approaches. In pregnant women with a history of miscarriage (N=193), the most frequently reported complementary approaches used were prayer (22.3%), yoga (15%), massage (14.5%), chiropractic (13%), and meditation (11.4%). Finally, after adjustment for age, race, education, and income, the odds of using a complementary approach in women with a history of miscarriage was 1.8 (95% CI: 1.3, 2.5, P<0.001) as compared with women without a history of miscarriage (model 1). Associations persisted after additional adjustment for depression, anxiety, and stress; the odds of using a complementary approach in women with a history of miscarriage was 1.7 (95% CI: 1.2, 2.4, P<0.001) (model 2), compared with women without a history of miscarriage. Findings from this study may help inform future studies for pregnant women with a history of miscarriage and may also provide information about appropriate strategies in which health care providers can refer their patients.

Methods: A retrospective case–controlled study was performed on 89 women with threatened miscarriage (study group) at Maternity and Children Hospital Buraidah, KSA from January 2010 to December 2010. They were matched for age and parity to 45 cases (control group) attending route antenatal clinic at the same time. Data recorded included, demographic characteristics and detailed pregnancy outcome and ultrasound finding including gestational age, cardiac activity and subchorionic hematoma. Results: The overall adverse pregnancy outcome was significantly higher in the studied cases compared to the control group (p=015).The miscarriage rate was significantly higher in study group compared to the controls group, (16.9%vs 2.2%, p=0000). Preterm delivery, babies with low birth weight and premature rupture of membranes were significantly higher in the miscarriage group compared to the controls group, (15.7% vs 2.2%, p=0.001), (15.7% vs 2.2%), p=0.001) and (6.7%) vs 4.45), p=0.016). There were no significant differences in other pregnancy outcomes. Conclusion: threatened miscarriage is associated with increased incidence of adverse pregnancy outcome. The risk is specially increased in premature rupture of the membranes, preterm delivery and neonatal birth weight. PMID:23678307

Objectives To identify and prioritise important research questions for miscarriage. Design A priority setting partnership using prospective surveys and consensus meetings following methods advocated by the James Lind Alliance. Setting UK. Participants Women and those affected by miscarriage working alongside healthcare professionals. Results In the initial survey, 1093 participants (932 women who have experienced miscarriage, 8 partners, 17 family members, friends or colleagues, 104 healthcare professionals and eight charitable organisations) submitted 3279 questions. A review of existing literature identified a further 64. Non-questions were removed, and the remaining questions were categorised and summarised into 58 questions. In an interim electronic survey, 2122 respondents chose their top 10 priorities from the 58 summary questions. The 25 highest ranked in the survey were prioritised at a final face-to-face workshop. In summary, the top 10 priorities were ranked as follows: research into preventative treatment, emotional aspects in general, investigation, relevance of pre-existing medical conditions, emotional support as a treatment, importance of lifestyle factors, importance of genetic and chromosomal causes, preconception tests, investigation after different numbers of miscarriage and male causal factors. Conclusions These results should be the focus of future miscarriage research. Presently, studies are being conducted to address the top priority; however, many other priorities, especially psychological and emotional support, are less well researched areas. We hope our results will encourage both researchers and funders to focus on these priorities. PMID:28838896

The p53 tumour suppressor gene is a well-known factor regulating apoptosis in a wide variety of cells and tissues. Alterations in the p53 gene are among the most common genetic changes in human cancers. In addition, recent data provide evidence that p53 plays a critical role in mediating pregnancy by regulating steroid hormone activation. In idiopathic recurrent miscarriages (IRM), causes and associations are much debated as the exact pathophysiological mechanisms are unknown. In this study, we assess whether an established polymorphism in the p53 gene is associated with the occurrence of IRM. Genotyping was performed by PCR-based amplification of the p53 Arg and Pro variants at codon 72 in 175 cases of IRM and 143 controls. We observed a statistically significant association between carriage of the Pro allele and the occurrence of IRM (P = 0.03, odds ratio 1.49, confidence interval 1.04-2.14). Distribution of genotypes was in Hardy-Weinberg equilibrium. Our results indicate an over-representation of the Pro allele of the p53 gene in women with IRM, giving support to the theory that p53 has a potential role during pregnancy.

Polymorphisms in TNF-a have been reported as genetic risk factors for recurrent spontaneous abortion and TNF-α may be immunologically important. We therefore examined the contribution of several TNF-a mutations to this phenomenon. The study participants consisted of 388 patients with idiopathic recurrent pregnancy loss (RPL), which was diagnosed on the basis of at least two consecutive spontaneous abortions; control subjects were 224 healthy women with a history of successful pregnancies. Polymerase chain reaction-restriction fragment length polymorphism analysis was performed to determine the TNF-α -863C>A, -857C>T, and +488G>A genotypes. The TNF-α -863C>A variants correlated with increased risk of RPL (CA+AA; adjusted odds ratio [AOR], 2.142; 95% confidence interval [CI], 1.493-3.074). These data did not differ in a stratified analysis according to number of consecutive spontaneous abortions. In haplotype analysis, there were similar trends of data for combination analysis, but in patients with 3+ pregnancy losses, a stratified analysis revealed that this correlation did not increase directly with the number of pregnancy losses. The TNF-α -863C>A variant is a possible genetic risk factor for idiopathic RPL in Korean women. Copyright © 2016 American Society for Histocompatibility and Immunogenetics. Published by Elsevier Inc.

Information on the reproductive effects of chemical exposures in dental work is sparse or inconsistent. To investigate whether dental workers exposed to acrylate compounds, mercury amalgam, solvents or disinfectants are at an increased risk of miscarriage. The study was conducted among women dental workers and a comparison group of workers occupationally unexposed to dental restorative materials. Information on pregnancies was obtained from national registers and outpatient units of hospitals. Data on occupational exposure were obtained using postal questionnaires. The final study population included 222 cases of miscarriage and 498 controls (births). An occupational hygienist assessed exposure to acrylate compounds, disinfectants and solvents. Exposure to other agents was assessed on the basis of the questionnaire data. Odds ratios (ORs) and confidence intervals (CIs) were estimated using conditional logistic regression. The ORs adjusted for confounding factors were increased for moderate-exposure and high-exposure categories of mercury amalgam (OR 2.0, 95% CI 1.0 to 4.1 and OR 1.3, 95% CI 0.6 to 2.5, respectively). The risk was slightly increased for the highest-exposure category of 2-hydroxyethylmethacrylate (OR 1.4, 95% CI 0.7 to 2.6) and polymethylmethacrylate dust (OR 1.4, 95% CI 0.8 to 2.4). A slightly increased risk was also detected for likely exposure to organic solvents (OR 1.4, 95% CI 0.8 to 2.3) and disinfectants (OR 1.5, 95% CI 0.9 to 2.7). No strong association or consistent dose-response relationship was observed between exposure to chemical agents in dental work and the risk of miscarriage. A slightly increased risk was found for exposure to mercury amalgam, some acrylate compounds, solvents and disinfectants. These findings indicate that the possibility of a weak association between exposure to these agents and an increased risk of miscarriage cannot be excluded.

 Existing information on acute idiopathic scrotal edema relies on small case series and textbooks.  We searched reports with no date limits on acute idiopathic scrotal edema.  Thirty-seven studies were included. Sixteen case series addressed the prevalence of acute idiopathic scrotal edema among males with acute scrotum: among 3,403 cases, the diagnosis of acute idiopathic scrotal edema was made in 413 cases (12%). Twenty-four reports addressed history, findings, management, and course of acute idiopathic scrotal edema in 311 patients. The patients mostly ranged in age from 5 to 8 years, presented with acute scrotal redness and swelling, associated or not with mild pain. Ninety percent or more of the cases developed in patients without atopic diathesis and were not preceded by inguinoscrotal surgery, acute febrile illnesses, or trauma. They were afebrile; in good general condition; and presented without pruritus, nausea or vomiting, or abdominal pain. The lesions were bilateral in two-thirds and unilateral in one-third of the cases. The condition resolved spontaneously within 2 to 3 days without sequelae. Approximately 10% of the cases experienced a recurrence.  Acute idiopathic scrotal edema is a self-limiting condition that accounts for ≥ 10% of cases of acute scrotum in children and adolescents.

Although miscarriage is common and affects up to 20% of pregnant women, little is known about these couples' short term and long term experiences after miscarriage. The aim of the present study was to study emotional experience, grief and depressive symptoms in women and men, one week and four months after miscarriage. Women, (n = 103), and their male partner (n = 78), were recruited at the gynecological clinic after miscarriage. Control women were recruited from the general population. Three validated questionnaires concerning psychological wellbeing and mental health, RIMS, PGS and MADRS-S were answered by the participants one week and four months after the miscarriage. It was shown that for women, the emotional experiences of miscarriage, grief and depressive symptoms were more pronounced than for their male partners. Grief and depressive symptoms were reduced with time, which was not the case for the emotional experiences of miscarriage. Previous children was favorable for emotional experience while previous miscarriage or infertility treatment made the emotional experience worse. Grief and depressive symptoms is reduced over time while emotional experiences such as isolation, loss of baby and a devastating event persist for longer time than four months. Lack of previous children, previous miscarriage and infertility diagnosis could increase negative emotional experiences after miscarriage, this was especially pronounced for grief reaction. The questionnaires could be used both clinically and in research to understand the emotional experiences after miscarriage. Copyright © 2018 Elsevier Ltd. All rights reserved.

Recurrent miscarriage (RM) affects 2-5% of pregnant women. Paternal lymphocyte immunotherapy is a common treatment for RM patients but the outcome has not been consistent. Therefore, combined therapy with other immunosuppressive drugs such as 1a, 25-dihydroxy-vitamin-D3 (vitamin D3) may improve the outcome. To investigate the effect of vitamin D3 on the balance of two essential T cells subsets, T helper (Th) 17 and T regulatory (Treg) cells, which contribute to the immune tolerance during pregnancy. The expression levels of CD4 and forkhead box protein 3 (FOXP3) in Treg cells, and the expression levels of CD4 and IL-17 in Th17 cells, were evaluated pre- and 3 months post-immunotherapy in RM patients treated with a combination of paternal lymphocytes and vitamin D3 compared with RM patients receiving lymphocyte immunotherapy alone. Vitamin D3 therapy decreased the frequency of Th17 cells in addition to reducing the Th17/Treg ratio in peripheral blood of RM patients compared with the control group (p<0.05). Considering that RM patients have a higher Th17/Treg ratio in peripheral blood, vitamin D3 may be a candidate therapeutic approach in this disease.

Intestinal Volvulus in Idiopathic Steatorrhea

1963-01-01

Volvulus of the intestine has recently been observed in three patients with idiopathic steatorrhea in relapse. Two patients gave a history of intermittent abdominal pain, distension and obstipation. Radiographic studies during these attacks revealed obstruction at the level of the sigmoid colon. Reduction under proctoscopic control was achieved in one instance, spontaneous resolution occurring in the other. The third patient presented as a surgical emergency and underwent operative reduction of a small intestinal volvulus. Persistence of diarrhea and weight loss postoperatively led to further investigation and a diagnosis of idiopathic steatorrhea. In all cases, treatment resulted in clinical remission with a coincident disappearance of obstructive intestinal symptoms. The pathogenesis of volvulus in sprue is poorly understood. Atonicity and dilatation of the bowel and stretching of the mesentery likely represent important factors. The symptoms of recurrent abdominal pain and distension in idiopathic steatorrhea necessitate an increased awareness of intestinal volvulus as a complication of this disease.

Recurrent Pericarditis.

PubMed

Imazio, Massimo; Gribaudo, Elena; Gaita, Fiorenzo

Recurrent pericarditis is the most common and troublesome complication of pericarditis affecting 20% to 50% of patients. Its pathogenesis is often presumed to be immune-mediated, but additional investigations are needed to clarify the pathogenesis in order to develop etiology-oriented therapies. Imaging with computed tomography and especially cardiac magnetic resonance holds promise to help in the identification of more difficult cases and improve their management. Refractory recurrent pericarditis with corticosteroid dependence and colchicine resistance remain still an unsolved issue in search of new therapies, although old drugs such as azathioprine, intravenous immunoglobulins, and biological agents seem promising, but new randomized clinical trials are needed to confirm their role. Despite compromising the quality of life, idiopathic recurrent pericarditis has an overall good long-term outcome without mortality and significant risk of constrictive pericarditis evolution. The risk of constriction, the most feared complication, is related to the etiology and not the number of recurrences. Copyright © 2016 Elsevier Inc. All rights reserved.

Uterine natural killer cells are the major leukocytes present in the periimplantation endometrium. Previous studies have found controversial differences in uterine natural killer cell percentage in women with recurrent reproductive failure compared with fertile controls. We sought to compare the uterine natural killer cell percentage in women with recurrent reproductive failure and fertile controls. This was a retrospective study carried out in university hospitals. A total of 215 women from 3 university centers participated in the study, including 97 women with recurrent miscarriage, 34 women with recurrent implantation failure, and 84 fertile controls. Endometrial biopsy samples were obtained precisely 7 days after luteinization hormone surge in a natural cycle. Endometrial sections were immunostained for CD56 and cell counting was performed by a standardized protocol. Results were expressed as percentage of positive uterine natural killer cell/total stromal cells. The median uterine natural killer cell percentage in Chinese ovulatory fertile controls in natural cycles was 2.5% (range 0.9-5.3%). Using 5th and 95th percentile to define the lower and upper limits of uterine natural killer cell percentage, the reference range was 1.2-4.5%. Overall, the groups with recurrent reproductive failure had significantly higher uterine natural killer cell percentage than the controls (recurrent miscarriage: median 3.2%, range 0.6-8.8%; recurrent implantation failure: median 3.1%, range 0.8-8.3%). However, there was a subset of both groups (recurrent miscarriage: 16/97; recurrent implantation failure: 6/34) that had lower uterine natural killer cell percentage compared to fertile controls. A reference range for uterine natural killer cell percentage in fertile women was established. Women with recurrent reproductive failure had uterine natural killer cell percentages both above and below the reference range. Copyright © 2017 Elsevier Inc. All rights reserved.

To investigate the risk factors for early miscarriage among Chinese women. Hospital-based matched case-control study. Academic medical center and maternal health hospital. 620 women with early miscarriage (less than 13 weeks of gestation) and 1,240 normal pregnant women. Face-to-face questionnaire. Multivariable conditional odds ratio (OR) and 95% confidence interval (CI) to measure risk factors. After adjustment for confounding factors, the following were independently associated with increased risk: history of miscarriage, repeated induced abortion, working night shifts, and frequent staying up late. Vitamin supplementation and regular physical activity reduced the risk of miscarriage. We did not find paternal age, alcohol consumption, or smoking status to be linked with early miscarriage. Our findings suggest that a healthy diet, regular physical activity, and planned pregnancy may be advantageous for women in pre-pregnancy or early pregnancy. Induced abortion, working night shifts, and frequent staying up late were associated with an increased risk of miscarriage. Further work in larger populations is warranted.

Recurrent miscarriage (RM) is one of the most common obstetric complications. Numerous studies have suggested that genetic variants leading to an impaired balance between coagulation and fibrinolysis may contribute to elevated risk of pregnancy loss. The aim of the study was to investigate a possible association between angiotensin-converting enzyme (ACE, rs1799752) I/D and plasminogen activator inhibitor type 1 (PAI-1, rs1799768) 4G/5G polymorphisms with RM among Polish women. DNA was extracted from peripheral blood samples of 152 women with a history of ≥ 2 consecutive pregnancy losses before 22 weeks of gestation, and 180 healthy controls with at least 1 live birth at term and no history of pregnancy loss. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) were used to identify the polymorphisms. No statistically significant differences were found in genotype and allele frequencies of the studied polymorphisms. The most relevant difference between the study group and controls was found for the ID genotype distribution of the ACE gene (52.6 vs. 46.7%, OR = 1.27, p = 0.28). The analysis of genotype coexistence revealed a higher incidence of the combination of the ACE II and the PAI-1 4G/4G genotypes in the control group (10.0 vs.5.9% in control group; p = 0.17). The obtained results suggest no apparent association between the ACE I/D, PAI-1 4G/5G polymorphisms and increased RM susceptibility in the analyzed Polish population.

Recurrent fetal loss (RFL) is a prevalent problem affecting approximately 1% of all women of childbearing age. Many factors can lead to RFL; however, recent studies have indicated the important role of the maternal immune system in this process. The human leukocyte antigens (HLA), HLA-linked genes and regulatory factors play an important role in fetal loss and in fetal development. The current retrospective study was preformed to examine the HLA alleles shared between couples with RFL in Saudi Arabia, using a large cohort of women (having three or more RFL). Specific HLA alleles that could influence this condition, or the number of miscarriages experienced, were expected to be highlighted in this way. A total of 253 consecutive patients who visited the RFL clinic at the King AbdulAziz Medical City, National Guard Hospital in Riyadh were included in this study. They included 54 consanguineous couples, 132 non-consanguineous couples and another 67 couples shared only their tribal origin. Clinical examinations as well as laboratory investigations were carried out on each patient. Class I HLA, HLA-A, HLA-B and HLA-C, and Class II HLA, HLA-DR and HLA-DQ, were typed for each patient and their partner. No relationship was seen between sharing of HLA alleles and the number of RFL experienced by the couples, among neither consanguineous nor non-consanguineous couples. Although the results of this study suggest that HLA sharing is not an indicative factor in RFL, definitive conclusions on this topic must be based on large case-control studies.

Idiopathic pulmonary fibrosis may be a disease of recurrent, tractional injury to the periphery of the aging lung: a unifying hypothesis regarding etiology and pathogenesis.

PubMed

Leslie, Kevin O

2012-06-01

Idiopathic pulmonary fibrosis is a progressive, fatal lung disease occurring in older individuals. Despite 50 years of accrued data about the disease, little progress has been made in slowing functional loss or in decreasing patient mortality. To present a novel hypothesis on the etiology and pathogenesis of idiopathic pulmonary fibrosis. Published data are reviewed regarding the epidemiology, clinical presentation, natural history, radiologic findings, and pathologic findings in patients with idiopathic pulmonary fibrosis. Patients with idiopathic pulmonary fibrosis may be predisposed genetically to tractional injury to the peripheral lung. The result is recurrent damage to the epithelial-mesenchymal interface, preferentially at the outer edges of the basilar lung lobules where tractional stress is high during inspiration, compliance is relatively low, and there is a greater tendency for alveolar collapse at end-expiration. A distinctive "reticular network of injury" (the fibroblast focus) forms, attended by a prolonged phase of wound repair (tear and slow repair). Discrete areas of alveolar collapse are observed in scar at the periphery of the lung lobules. The cycle repeats over many years resulting in progressive fibrous remodeling and replacement of the alveoli in a lobule by bronchiolar cysts surrounded by scar (honeycomb lung). Abnormalities in surfactant function are proposed as a potential mechanism of initial lung damage. Age of onset may be a function of a required threshold of environmental exposures (eg, cigarette smoking) or other comorbid injury to the aging lung. Evidence supporting this hypothesis is presented and potential mechanisms are discussed. A potential role for contributing cofactors is presented.

The incidence of missed miscarriage has been increasing during the past decade in China and the etiology of about half of the cases remains unclear. Exposure to phthalates has been considered as a risk factor. The aim of this paper is to assess the association between exposure to phthalates and missed miscarriage. A case-control study was performed including 150 cases of missed miscarriage and 150 matched controls with normal pregnancies. The levels of phthalate exposure were compared between the two groups by measuring 13 phthalate metabolites in urine samples. Blood samples were collected for serum hormone measurement to assess the relationship between serum hormone level and phthalate exposure. The urinary levels of metabolites of di-(2-ethylhexyl) phthalate (DEHP) and dimethyl phthalate (DMP) were significantly higher in the cases than in the controls. A strong dose-response relationship was observed between urinary metabolite levels and the odds of missed miscarriage. Monomethyl phthalate (MMP), a metabolite of DMP, and mono-2-ethylhexyl phthalate (MEHP), a metabolite of DEHP, each had significant negative correlation with maternal serum hormone levels. In the current study, exposure to DEHP and DMP was found to be associated with missed miscarriage. Interruption of hormone synthesis by DMP and DEHP metabolites represents a plausible mechanism of phthalate reproductive toxicity.

Systematic review and meta-analysis. Not applicable. Couples with IRSA and their spontaneously aborted embryos. Summary odds ratios (ORs) were calculated by means of fixed- or random-effects models. Association of genetic variants with IRSA. The systematic review included 428 case-control studies (1990-2015), which differed substantially regarding RSA definition, clinical evaluation of patients, and selection of control subjects. In women, 472 variants in 187 genes were investigated. Meta-analyses were performed for 36 variants in 16 genes. Association with IRSA defined as three or more spontaneous abortions (SAs) was detected for 21 variants in genes involved in immune response (IFNG, IL10, KIR2DS2, KIR2DS3, KIR2DS4, MBL, TNF), coagulation (F2, F5, PAI-1, PROZ), metabolism (GSTT1, MTHFR), and angiogenesis (NOS3, VEGFA). However, ORs were modest (0.51-2.37), with moderate or weak epidemiologic credibility. Minor differences in summary ORs were detected between IRSA defined as two or more and as three or more SAs. Male partners were included in 12.1% of studies, and one study included spontaneously aborted embryos. Candidate gene studies show moderate associations with IRSA. Owing to large differences in RSA definition and selection criteria for participants, consensus is needed. Future GASs should include both partners and spontaneously aborted embryos. Genome-wide association studies and large-scale replications of identified associations are recommended. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

There are many occupational health hazards associated with long hours of air travel, including cosmic radiation exposure, circadian rhythm disruptions, prior and secondhand smoke exposure, for flight attendants who flew before smoking bans were initiated in the 1990s. Previous studies in flight attendants have found increased incidence of breast cancer and melanoma. However, there is little information on the relationship of airline travel and reproductive health in flight attendants. Secondhand smoke exposure has numerous negative health effects, such as increased cardiac events and respiratory infections, but its effect on reproductive health is not known. This study seeks to examine the role of secondhand smoke exposure on the miscarriage rate in flight attendants who flew before the smoking ban. Flight attendants who flew before the smoking ban and participating in a study of health effects of secondhand smoke were asked to complete a reproductive health survey. We compared miscarriage rates of flight attendants to the general population using 2010 data from the Centers for Disease Control and Prevention. In our cohort of 145 female flight attendants exposed to secondhand smoke, there were 45 miscarriages (26%), compared with a 17.1% rate in the Centers for Disease Control and Prevention report (P = .002). There was no difference in secondhand smoke exposure between the flight attendants with miscarriage and the group without miscarriage (P = .93). This study found an increased incidence of miscarriage in flight attendants, which was unrelated to secondhand smoke exposure. Other factors, such as circadian rhythm disruption and radiation, may be related to these reproductive health findings and require further investigation. Copyright © 2017 Elsevier Inc.

To investigate the prevalence of miscarriage in women with endometriosis (WwE) compared with disease-free control women (CW). Cross-sectional analysis nested in a retrospective observational study (n = 940). Hospitals and associated private practices. Previously pregnant women (n = 268) within reproductive age in matched pairs. Retrospective analysis of surgical reports and self-administered questionnaires. Rate of miscarriage, subanalysis for fertility status (≤12 vs. >12 months' time to conception), endometriosis stages (revised American Society of Reproductive Medicine classification [rASRM] I/II vs. III/IV) and phenotypic localizations (superficial peritoneal, ovarian, and deep infiltrating endometriosis). The miscarriage rate was higher in WwE (35.8% [95% confidence interval 29.6%-42.0%]) compared with CW (22.0% [16.7%-27.0%]); adjusted incidence risk ratio of 1.97 (95% CI 1.41-2.75). This remained significant in subfertile WwE (50.0% [40.7%-59.4%]) vs. CW (25.8% [8.5%-41.2%]) but not in fertile WwE (24.5% [16.3%-31.6%]) vs. CW (21.5% [15.9%-26.8%]). The miscarriage rate was higher in women with milder forms (rASRM I/II 42.1% [32.6%-51.4%] vs. rASRM III/IV 30.8% [22.6%-38.7%], compared with 22.0% [16.7%-27.0%] in CW), and in women with superficial peritoneal endometriosis (42.0% [32.0%-53.9%]) compared with ovarian endometriosis (28.6% [17.7%-38.7%]) and deep infiltrating endometriosis (33.9% [21.2%-46.0%]) compared with CW (22.0% [16.7%-27.0%]). Mild endometriosis, as in superficial lesions, is related to a great extent of inflammatory disorder, possibly leading to defective folliculogenesis, fertilization, and/or implantation, presenting as increased risk of miscarriage.

Recurrent panniculitis in children with lipoatrophy has been loosely described and reported under different names, but has never been systematically evaluated by immunohistochemical stains. To depict the profile of children with recurrent idiopathic panniculitis. Study of clinical, histopathological and immunohistochemical features in five cases with recurrent idiopathic panniculitis. Five children with repeated attacks of painful subcutaneous nodules in association with fever, malaise and abdominal pain or arthralgia, with subsequent lipoatrophy were reviewed. In two patients, extensive involvement led to loss of the cutaneous fatty tissue. Laboratory abnormalities included increased acute phase reactants, leukocytosis with mild neutrophilia, microcytic anaemia and elevated liver enzymes. Histopathology showed lobar panniculitis without vasculitis and with a mixed infiltrate, composed of neutrophils, mononuclear cells, lymphocytes, macrophages and myeloid cells. Neutrophils and myeloid cells were more prominent in early lesions, whereas macrophages predominated in late stages, leading to lipophagia and lipoatrophy. Immunohistochemistry showed positive staining for myeloperoxidase around the necrotic adipocytes in early stages and CD68/PGM1 macrophages in late stages. Intense STAT1 staining was observed in the inflammatory infiltrate. All patients improved with methotrexate and corticosteroids. We present five cases of lobar panniculitis and lipoatrophy in childhood. The clinico-pathologic presentation shares features with other autoinflammatory diseases. © 2016 European Academy of Dermatology and Venereology.

Giant scrotal elephantiasis: an idiopathic case.

2010-01-01

Scrotal elephantiasis is very rare disease in industrialized countries, where it is mainly due to surgery, irradiation or malignancies. It can be defined as idiopathic only when the possible congenital, infectious and compressive causes are excluded. We report a case of massive scrotal lymphoedema in an adult Caucasian patient, in Italy. He presented an extremely voluminous scrotal mass measuring 50 x 47 x 13 cm (weight 18 kg), which extended below his knees, invalidating all his daily activities. The patient was hospitalized in order to undergo to surgical treatment. Although genetic causes were searched and the possible role of infectious agents and compressive factors was evaluated, no etiology was ascertained. Histopathologic examination showed non-specific chronic inflammation, confirming the diagnosis of idiopathic elephantiasis. One year after surgical treatment, the patient is healthy without recurrence signs.

Situating stigma in stratified reproduction: Abortion stigma and miscarriage stigma as barriers to reproductive healthcare.

To examine whether race and reported history of abortion are associated with abortion stigma and miscarriage stigma, both independently and comparatively. Self-administered surveys with 306 new mothers in Boston and Cincinnati, United States. Abortion stigma perception (ASP); miscarriage stigma perception (MSP); and comparative stigma perception (CSP: abortion stigma perception net of miscarriage stigma perception). Regardless of whether or not they reported having an abortion, white women perceived abortion (ASP) to be more stigmatizing than Black and Latina women. Perceptions of miscarriage stigma (MSP), on the other hand, were dependent on reporting an abortion. Among those who reported an abortion, Black women perceived more stigma from miscarriage than white women, but these responses were flipped for women who did not report abortion. Reporting abortion also influenced our comparative measure (CSP). Among those who did report an abortion, white women perceived more stigma from abortion than miscarriage, while Black and Latina women perceived more stigma from miscarriage than abortion. By measuring abortion stigma in comparison to miscarriage stigma, we can reach a more nuanced understanding of how perceptions of reproductive stigmas are stratified by race and reported reproductive history. Clinicians should be aware that reproductive stigmas do not similarly affect all groups. Stigma from specific reproductive outcomes is more or less salient dependent upon a woman's social position and lived experience. Copyright © 2016 Elsevier B.V. All rights reserved.

Despite advances in the diagnosis and management of idiopathic noncirrhotic portal hypertension, its pathogenesis remains elusive. Insight may be gained from study of early-onset familial idiopathic noncirrhotic portal hypertension, in which Mendelian mutations may account for disease. We performed exome sequencing of eight subjects from six kindreds with onset of portal hypertension of indeterminate etiology during infancy or childhood. Three subjects from two consanguineous families shared the identical rare homozygous p.N46S mutation in DGUOK, a deoxyguanosine kinase required for mitochondrial DNA replication; haplotype sharing demonstrated that the mutation in the two families was inherited from a remote common ancestor. All three affected subjects had stable portal hypertension with noncirrhotic liver disease for 6-16 years of follow-up. This mutation impairs adenosine triphosphate binding and reduces catalytic activity. Loss-of-function mutations in DGUOK have previously been implicated in cirrhosis and liver failure but not in isolated portal hypertension. Interestingly, treatment of patients with human immunodeficiency viral infection with the nucleoside analogue didanosine is known to cause portal hypertension in a subset of patients and lowers deoxyguanosine kinase levels in vitro; the current findings implicate these effects on deoxyguanosine kinase in the causal mechanism. Our findings provide new insight into the mechanisms mediating inherited and acquired noncirrhotic portal hypertension, expand the phenotypic spectrum of DGUOK deficiency, and provide a new genetic test for a specific cause of idiopathic noncirrhotic portal hypertension.

Miscarriage affects around one in six pregnancies. Much research has taken place identifying the consequences of this for parents but is mainly quantitative. Of the limited qualitative studies, none have explored women's experiences of the methods of miscarriage management received. To assess the social and personal impact of different management methods (expectant, medical and surgical) on women's experience of first trimester miscarriage. Qualitative interviews using a topic guide with a purposive cohort of four categories of women (each management method plus non-participants) 6 months to 1 year after first trimester miscarriage. Focus groups with both research participants and health workers. Women from three hospitals in the South West of England that participated in the Miscarriage Treatment (MIST) trial. Seventy-two interviews were undertaken between September 1999 and June 2000. There were also five focus groups (47 participants) and two feedback sessions (8 participants) with written feedback from 12 women. Interviews lasted 0.5-2.5 hours generating over 2000 A4 pages of transcripts. The transcripts were analysed for common themes, using standard proformas, which were filled in by individual team members and then discussed by the whole research team. Iterative readings in the light of new emerging issues ensured that new themes could be identified throughout the analytical process. All transcripts were then encoded for the identified themes using NUDIST. Common themes emerged across all management options although some were specific to just one or two management options. The five major themes arising out of the data analysis were: intervention; experiences of care; finality; the 'baby'; and pain and bleeding. Women's experiences and beliefs vary widely and their preferences need to be considered in their early miscarriage management. The three methods have different benefits and problems from the women's point of view. Competence and caring from

The Consequences of Teenage Childbearing: Consistent Estimates When Abortion Makes Miscarriage Nonrandom*

Miscarriage, even if biologically random, is not socially random. Willingness to abort reduces miscarriage risk. Because abortions are favorably selected among pregnant teens, those miscarrying are less favorably selected than those giving birth or aborting but more favorably selected than those giving birth. Therefore, using miscarriage as an instrument is biased towards a benign view of teen motherhood while OLS on just those giving birth or miscarrying has the opposite bias. We derive a consistent estimator that reduces to a weighted average of OLS and IV when outcomes are independent of abortion timing. Estimated effects are generally adverse but modest. PMID:24443589

Leung, Ping Chung; Chung, Tony Kwok Hung; Wang, Chi Chiu

Background. Miscarriage is a very common complication during early pregnancy. So far, clinical therapies have limitation in preventing the early pregnancy loss. Chinese Medicine, regarded as gentle, effective, and safe, has become popular and common as a complementary and alternative treatment for miscarriages. However, the evidence to support its therapeutic efficacy and safety is still very limited. Objectives and Methods. To summarize the clinical application of Chinese Medicine for pregnancy and provide scientific evidence on the efficacy and safety of Chinese medicines for miscarriage, we located all the relevant pieces of literature on the clinical applications of Chinese Medicine for miscarriage and worked out this systematic review. Results. 339,792 pieces of literature were identified, but no placebo was included and only few studies were selected for systematic review and conducted for meta-analysis. A combination of Chinese medicines and Western medicines was more effective than Chinese medicines alone. No specific safety problem was reported, but potential adverse events by certain medicines were identified. Conclusions. Studies vary considerably in design, interventions, and outcome measures; therefore conclusive results remain elusive. Large scales of randomized controlled trials and more scientific evidences are still necessary to confirm the efficacy and safety of Chinese medicines during early pregnancy. PMID:24648851

Chromosomal abnormalities as a cause of recurrent abortions in Egypt

El-Dahtory, Faeza Abdel Mogib

2011-01-01

BACKGROUND: In 4%-8% of couples with recurrent abortion, at least one of the partners has chromosomal abnormality. Most spontaneous miscarriages which happen in the first and second trimesters are caused by chromosomal abnormalities. These chromosomal abnormalities may be either numerical or structural. MATERIAL AND METHODS: Cytogenetic study was done for 73 Egyptian couples who presented with recurrent abortion at Genetic Unit of Children Hospital, Mansoura University. RESULTS: We found that the frequency of chromosomal abnormalities was not significantly different from that reported worldwide. Chromosomal abnormalities were detected in 9 (6.1%) of 73 couples. Seven of chromosomal abnormalities were structural and two of them were numerical. CONCLUSION: Our results showed that 6.1% of the couples with recurrent abortion had chromosomal abnormalities, with no other abnormalities. We suggest that it is necessary to perform cytogenetic in vestigation for couples who have recurrent abortion. PMID:22090718

Objective To determine whether multivitamin supplements modify the relationship between alcohol consumption during pregnancy and the risk of miscarriage. Study Design We utilized data from a population-based cohort study of pregnant women (n=1061; response rate=39%). Participants were asked about their alcohol consumption and vitamin intake during pregnancy. Results Among multivitamin nonusers, women who drank alcohol during their pregnancy were more likely to have a miscarriage compared to women who abstained (adjusted Hazard Ratio (aHR): 1.67, 95%CI: 1.04, 2.69). However among multivitamin users, there was no difference in the risk of miscarriage between alcohol consumers and abstainers. Results suggest the volume of alcohol as well as the timing of multivitamin supplementation may also be important. Conclusions Our findings suggest that a woman of child-bearing years might decrease her risk of miscarriage associated with alcohol intake by taking multivitamin supplements. However, our findings should be interpreted with caution and future research replicating these findings is necessary. PMID:19846052

To study the profile and long-term outcome of Indian patients presenting with acute pancreatitis and the possible risk factors for progression. Consecutive patients with acute or recurrent acute pancreatitis seen in our department during July 2013 to December 2014 were included. Details of past episodes were collected and patients were followed up till March 2015. In the 97 patients included (mean age 47.2 [SD 16.9] years; 74 men), gallstones (37 [38.1%]) and alcohol (19 [19.6%]) were the major identified etiologies; the idiopathic (31 [32%]) group constituted a third of patients. Recurrences were more common with idiopathic etiology (14 patients out of 30 had recurrences [46.7%]) as compared to alcoholic (5 out of 19 [26.3%]) and biliary (4 out of 37 [10.8%]) pancreatitis and with mild index episode. Following the episode of acute pancreatitis, identification of chronic pancreatitis was more common with alcoholic (6 out of 18 [33%]) and idiopathic (9 out of 30 [30%]) etiology as compared to other etiologies. Longer duration of follow up, but not number of recurrent episodes, was associated with identification of chronicity in patients presenting as acute pancreatitis. Out of 97 patients with acute pancreatitis, 27 (27.8%) developed recurrences with risk factors being idiopathic etiology and mild index episode. Eighteen of 97 (18.6%) patients had evidence of chronic pancreatitis on follow up, risk factors being the alcoholic and idiopathic varieties, and longer duration of follow up.

Systematic Review and Meta-Analysis of Miscarriage and Maternal Exposure to Tobacco Smoke During Pregnancy

2014-01-01

We conducted a systematic review and meta-analysis to characterize the relationship between smoking and miscarriage. We searched the PubMed database (1956–August 31, 2011) using keywords and conducted manual reference searches of included articles and reports of the US Surgeon General. The full text of 1,706 articles was reviewed, and 98 articles that examined the association between active or passive smoking and miscarriage were included in the meta-analysis. Data were abstracted by 2 reviewers. Any active smoking was associated with increased risk of miscarriage (summary relative risk ratio = 1.23, 95% confidence interval (CI): 1.16, 1.30; n = 50 studies), and this risk was greater when the smoking exposure was specifically defined as during the pregnancy in which miscarriage risk was measured (summary relative risk ratio = 1.32, 95% CI: 1.21, 1.44; n = 25 studies). The risk of miscarriage increased with the amount smoked (1% increase in relative risk per cigarette smoked per day). Secondhand smoke exposure during pregnancy increased the risk of miscarriage by 11% (95% CI: 0.95, 1.31; n = 17 studies). Biases in study publication, design, and analysis did not significantly affect the results. This finding strengthens the evidence that women should not smoke while pregnant, and all women of reproductive age should be warned that smoking increases the risk of miscarriage. PMID:24518810

Self-reported Vitamin Supplementation in Early Pregnancy and Risk of Miscarriage

Miscarriage is a common and poorly understood adverse pregnancy outcome. In this study, the authors sought to evaluate the relation between self-reported use of prenatal vitamins in early pregnancy and the risk of miscarriage. Between 2000 and 2008, 4,752 US women were prospectively enrolled in Right From the Start. Information about vitamin use was obtained from a first-trimester interview. Discrete-time hazard models were used, candidate confounders were assessed, and the following variables were included in the model: study site, maternal age, gravidity, marital status, education, race/ethnicity, smoking, and use of progesterone in early pregnancy. Approximately 95% of participants reported use of vitamins during early pregnancy. A total of 524 women had a miscarriage. In the final adjusted model, any use of vitamins during pregnancy was associated with decreased odds of miscarriage (odds ratio = 0.43, 95% confidence interval: 0.30, 0.60) in comparison with no exposure. These results should be viewed in the context of a potentially preventive biologic mechanism mitigated by possible confounding by healthy behaviors and practices that are also associated with vitamin supplement use during pregnancy.

Miscarriage is the most common negative outcome of pregnancy, and identification of modifiable risk factors is potentially of great importance for public health. Low vitamin D concentrations in pregnancy are widespread worldwide, and vitamin D deficiency is implicated in immune cell regulation at the feto-maternal interface and several diseases of pregnancy. We investigated whether 25-hydroxyvitamin D serum concentration was a modifiable risk factor for early miscarriage. In a prospective cohort study of 1683 pregnant women donating serum before gestational week 22, we investigated the association between maternal serum concentrations of serum 25-hydroxyvitamin D [25(OH)D] and the risk of subsequent miscarriage (n = 58). The adjusted hazard of first-trimester miscarriage was lower with higher 25(OH)D concentrations (HR: 0.98; 95% CI: 0.96, 0.99). Concentrations of 25(OH)D <50 nmol/L were associated with a >2-fold increased adjusted HR for miscarriage (HR: 2.50; 95% CI: 1.10, 5.69). Concentrations of 25(OH)D were not associated with an increased risk of second-trimester miscarriage. We found an association between 25(OH)D and first-trimester miscarriages, suggesting vitamin D as a modifiable risk factor for miscarriage. To test this hypothesis, randomized controlled trials should investigate the possible effect of vitamin D supplementation to increase 25(OH)D concentrations in early pregnancy, or before conception, to decrease risk of miscarriage.

The early miscarriage rate is reported to be higher in patients with polycystic ovary syndrome (PCOS) compared with non-PCOS patients. However, whether PCOS is an independent risk factor for early miscarriage is still controversial; to what extent embryonic aneuploidy accounts for miscarriages of PCOS is still unknown. In this 1:3 matched-pair study, 67 lean PCOS patients and 201 controls matched for age, body mass index (BMI) and embryo scores undergoing a single euploid blastocyst transfer in vitrified-warmed cycles were analysed. Clinical pregnancy, early miscarriage and live birth rates were compared. Logistic regression analysis was performed to further evaluate the factors associated with early miscarriage and live birth. Clinical pregnancy rates were 50.7% in PCOS and 55.2% in control groups. Early miscarriage rate was significantly (P = 0.029) increased in the PCOS group compared with controls; non-PCOS patients had a significantly higher live birth rate than PCOS patients, P < 0.001. Further regression analyses showed that PCOS was significantly associated with a higher risk of early miscarriage and decreased chance of live birth. In conclusion, PCOS in women undergoing pre-implantation genetic diagnosis may, independently from BMI and karyotype, increase the risk of miscarriage. Copyright © 2017 Reproductive Healthcare Ltd.

Despite research documenting high rates of violence during pregnancy, few studies have examined the impact of physical abuse, psychological abuse, and posttraumatic stress disorder (PTSD) on miscarriage. Secondary analysis of data collected by the Chicago Women's Health Risk Study permitted an exploration of the relationships among physical abuse, psychological abuse, PTSD, and miscarriage among 118 primarily ethnic minority women. The interaction between maximum severity of abuse and age provided the best multivariate predictor of miscarriage rate, accounting for 26.9% of the variance between live birth and miscarriage outcome. Mean scores of psychological abuse, physical violence, forced sex, and PTSD were significantly higher in the miscarriage group than in the live birth group. Women who experience physical violence and psychological abuse during pregnancy may be at greater risk for miscarriage. Prospective studies can confirm findings and determine underlying mechanisms. Routine screening for traumatic stress and PTSD may reduce rates of miscarriage.

Miscarriage, abortion or criminal feticide: understandings of early pregnancy loss in Britain, 1900-1950.

PubMed

Elliot, Rosemary

2014-09-01

This paper explores the close links in medical understandings of miscarriage and abortion in the first half of the twentieth century in Britain. In the absence of a clear legal framework for abortion, and the secrecy surrounding the practice, medical literature suggests contradictory and confused views about women presenting with clinical signs of pregnancy loss. On one hand, there was a lack of clarity as to whether pregnancy loss was natural or induced, with a clear tendency to assume that symptoms of miscarriage were the result of criminal interference gone wrong. On the other hand, women who did not present for treatment when miscarriage was underway were accused of neglecting their unborn children. The paper suggests that discourses around pregnancy loss were class-based, distrustful of female patients, and shaped by the wider context of fertility decline and concerns about infant mortality. The close historical connection between miscarriage and abortion offers some insight into why both the pro-life movement and miscarriage support advocates today draw on similar imagery and rhetoric about early fetal loss.

Long term follow up of idiopathic gingival enlargement associated with chronic periodontitis: A case report and review.

PubMed

Nagarale, Girish P; Ravindra, S; Thakur, Srinath; Setty, Swati

2013-03-01

Idiopathic gingival enlargement is a rare condition characterized by massive enlargement of the gingiva. It may be associated with other diseases/conditions characterizing a syndrome, but rarely associated with periodontitis. This case report describes an unusual clinical form of gingival enlargement associated with chronic periodontitis. Clinical examination revealed diffuse gingival enlargement. The lesion was asymptomatic, firm, and pinkish red. Generalized periodontal pockets were observed. Radiographic evaluation revealed generalized severe alveolar bone loss. Histopathological investigations revealed atrophic epithelium with dense fibrocollagenous tissue. Lesions healed successfully following extraction and surgical excision, and no recurrence was observed after 1 year follow-up but recurrence was observed at 3 and 5-years follow-up. Successful treatment of idiopathic gingival enlargement depends on proper identification of etiologic factors and improving esthetics and function through surgical excision of the over growth. However, there may be recurrence.

To evaluate prospectively the efficacy of methotrexate (MTX) in the treatment of recurrent idiopathic acute anterior uveitis (RIAAU). Nineteen out of 22 RIAAU patients completed the study (two patients withdrew their consent shortly after study initiation, one patient discontinued after 4 weeks because of the adverse effects). All patients were treated with MTX in a starting dose of 15 mg/week, increased to target dose of 25 mg/week after 4 weeks. In patients taking systemic corticosteroids (CS) the dose was gradually tapered (by 2.5 mg every week) until discontinuation. The mean follow-up period was 3.3 years (19-59 months). Sixteen patients (84 %) remained flare-free on MTX therapy. In the remaining three patients the mean interval between flares increased from 4.8 to 18.3 months. Systemic CS were tapered off in all patients. The number of acute anterior uveitis flares in the whole cohort decreased from 2.12 to 0.11/patient-year (p < 0.0001). All flares observed on MTX therapy occurred in HLA-B27-positive patients. MTX dosed at 25 mg/week is highly effective in the treatment of RIAAU.

women who have experienced miscarriage may be at increased risk for elevated depressive and anxiety symptoms in subsequent pregnancies. Exercise may be a useful strategy for coping with these symptoms. Little is known about how miscarriage influences prenatal exercise behavior. The study purpose was to examine the influences of miscarriage history and prepregnancy weight status on pregnant women's psychological health, exercise motivation, and behavior using the Theory of Planned Behavior. Pregnant women (N=203; 41 with prior miscarriage; 72 overweight/obese; BMI > 25.0) in the northeast United States. Women prospectively reported their depressive/anxiety symptoms and exercise motivation/behavior in the 1st, 2nd, and 3rd trimesters via mailed surveys. Group differences in depressive/anxiety symptoms, exercise behavior, and its motivational determinants were examined using Chi Square analyses and Univariate and Multivariate Analyses of Covariance. Women with a history of miscarriage had higher 1st and 2nd trimester depressive/anxiety symptoms and lower 1st trimester attitudes about exercise and 1st and 2nd trimester perceived behavior control than women without a history of miscarriage. Overweight/obese women had higher 1st and 2nd trimester pregnancy depressive/anxiety symptoms, engaged in less prepregnancy exercise, and had lower levels of exercise intention, attitude, and perceived behavior control throughout pregnancy than normal weight women. Women with a history of miscarriage and overweight/obese women have poorer psychological health and lower motivation to exercise during pregnancy than women without a history of miscarriage and normal weight women. Interventions and healthcare provider communications aimed at promoting perinatal exercise behavior and psychological health should take into account pre-pregnancy weight status and pregnancy history to identify strategies to help women, particularly overweight/obese women with a history of miscarriage, to

The present study was undertaken to determine the role of different polymorphisms affecting the testosterone/oestrogen pathway in miscarriage. Alpha 5-reductase (SRD5A2) rs523349 and rs9282858, cytochrome P450 aromatase (CYP19A1) rs4646, rs10046 and rs2236722 and oestrogen receptor (ESR1) rs9340799, rs2234693 and rs6932902 polymorphisms were selected. The case group consisted of 94 samples of formalin-fixed and paraffin-embedded fetal tissue from a miscarriage at ≤24 weeks. The control group comprised a population of 331 young healthy subjects. Only those single nucleotide polymorphisms (SNPs) fitting the Hardy-Weinberg equilibrium (n = 4) and euploid miscarriage samples (n = 67) were included for downstream analysis. Interestingly, SRD5A2 rs523349 (Val89Leu) was significantly associated with the risk of undergoing miscarriage after Bonferroni correction (odds ratio = 11.245, P < 2.2 × 10 -9 ). Moreover, when Mantel-Cox regression analysis was performed, we observed that the effect was significantly constrained to the second trimester (P = 0.024, log rank). These results are compatible with an imbalance of testosterone/dihydrotestosterone, associated with a higher risk of miscarriage, especially in late pregnancy.

2017-03-01

A short interpregnancy interval (IPI) following a delivery is believed to be associated with adverse outcomes in the next pregnancy. The optimum IPI following miscarriage is controversial. Based on a single large-scale study in Latin and South America, the World Health Organization recommends delaying pregnancy for 6 months after a miscarriage to achieve optimal outcomes in the next pregnancy. Our aim was to determine if a short IPI (<6 months) following miscarriage is associated with adverse outcomes in the next pregnancy. Studies were retrieved from MEDLINE, Embase and Pubmed, with no time and language restrictions. The search strategy used a combination of Medical Subject Headings terms for miscarriage, IPI and adverse outcomes. Bibliographies of the retrieved articles were also searched by hand. All studies including women with at least one miscarriage, comparing subsequent adverse pregnancy outcomes for IPIs of less than and more than 6 months were included. Two independent reviewers screened titles and abstracts for inclusion. Characteristics of the studies were extracted and quality assessed using Critical Appraisal Skills Programme criteria. A systematic review and meta-analysis were conducted to compare short (<6 months) versus long (>6 months) IPI following miscarriage in terms of risk of further miscarriage, preterm birth, stillbirth, pre-eclampsia and low birthweight babies in the subsequent pregnancy. Review Manager 5.3 was used for conducting meta-analyses. Sixteen studies including 1 043 840 women were included in the systematic review and data from 10 of these were included in one or more meta-analyses (977 972 women). With an IPI of less than 6 months, the overall risk of further miscarriage (Risk ratio (RR) 0.82 95% CI 0.78, 0.86) and preterm delivery (RR 0.79 95% CI 0.75, 0.83) were significantly reduced. The pooled risks of stillbirth (RR 0.88 95% CI 0.76, 1.02); low birthweight (RR 1.05 95% CI 0.48, 2.29) and pre-eclampsia (RR 0.95 95% CI 0

There has been recent evidence suggesting the presence of anti-thyroid peroxidase antibodies (TPOAb) increases the risk of miscarriage, and levothyroxine can rescue miscarriages associated with TPOAb. We propose the most clinically pragmatic cohort to screen for TPOAb are women presenting for management of a missed miscarriage and have never birthed a liveborn. We measured serum TPOAb among nulliparous women presenting for management of miscarriage, and compared levels with women who have had 2 or more livebirths (and never miscarried). Given its potential role in immunomodulation, we also measured Vitamin D levels. We performed a prospective descriptive cohort study at a tertiary hospital (Mercy Hospital for Women, Victoria, Australia). We measured TPOAb and Vitamin D levels in serum obtained from 118 nulliparous women presenting for management of miscarriage, and 162 controls with 2 or more livebirths (and no miscarriages). Controls were selected from a serum biobank prospectively collected in the first trimester at the same hospital. Nulliparous women with 1 or more miscarriages had higher thyroid peroxidase antibody (TPOAb) levels than those with 2 or more livebirths; TPOAb in miscarriage group was 0.3 mIU/L (interquartile range [IR]: 0.2-0.7) vs 0.2 mIU/L among controls (IR 0.0-0.5; p < 0.0001). We confirmed TPOAb levels were not correlated with serum human chorionic gonadotrophin (hCG) concentrations in either the miscarriage or control groups. In contrast, thyroid stimulating hormone, fT3 and fT4 levels (thyroid hormones) either trended towards a correlation, or were significantly correlated with serum hCG levels in the two groups. Of the entire cohort that was predominantly caucasian, only 12% were Vitamin D sufficient. Low Vitamin D levels were not associated with miscarriage. We have confirmed the association between miscarriage and increased TPOAb levels. Furthermore, it appears TPOAb levels in maternal blood are not influenced by serum hCG levels

To investigate the effects of negative emotions and life events on women's missed miscarriage. Overall, 214 women diagnosed with a missed miscarriage by prenatal examination from 2016-2017 in Xiamen Maternal and Child Health Care Hospital, Xiamen, China were selected as the observation group compared to 214 women as control group. The general data of the patients were investigated by self-programmed questionnaires. Zung Self-Rating Anxiety Scale, Center Epidemiological Studies Depression Scale; Life Events Scale for Pregnant Women were used conduct the study. General data, anxiety, depression and life events were compared between the two groups of patients, and statistically different factors were included in the multivariate Logistic regression analysis. There were statistically significant differences in the educational level, pre-pregnancy health status, planned pregnancy, pre-pregnancy or gestational gynecological inflammation and the initiative to obtain knowledge of prenatal and postnatal care between the two groups of pregnant women ( P <0.01); there were also statistically significant differences in score of life events, score of anxiety and score of depression between them ( P <0.01). The high educational level, good health status before pregnancy and the initiative to obtain the knowledge of prenatal and postnatal care were taken as the independent protective factors for the missed miscarriage in pregnant women, while life events, anxiety and depression were independent risk factors for it. Negative emotions and life events increase the risk of women's missed miscarriage, and the high educational level, good health status before pregnancy and the initiative to obtain the knowledge of prenatal and postnatal care reduce the risk of women's missed miscarriage.

Human intravenous immunoglobulins (hIVIgs) are used in two broad categories of diseases: immunodeficiency and autoimmunity. Among the immune-mediated diseases hIVIgs are of benefit in idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, and dermatomyositis. Chronic idiopathic pericarditis (CIP) is a chronic disease of unknown origin characterized by recurrent episodes of pericardial inflammation. The cause of the recurrence is unknown, although in some cases it may be traced to a viral infection and to the presence of antimyocardial antibodies. Since a viral infection can induce an autoimmune process through a mechanism of molecular mimicry, and since the optimal therapy for prevention of the recurrences has not been established, we reasoned that treatment with hIVIgs could be beneficial in our patients unresponsive to previous immunosuppressive therapies. We describe four patients affected by CIP treated with monthly high-dose hIVIgs (0.4 g/kg daily for 5 consecutive days) for five times followed by administration every 2 months. Three of the four patients could permanently discontinue steroid therapy and are still in remission after years of follow-up. Our experience suggests that hIVIgs therapy may be a useful and safe treatment for CIP in steroid-dependent patients.

Anxiety after miscarriage: a review of the empirical literature and implications for clinical practice.

PubMed

Brier, Norman

2004-06-01

Most practitioners now view a miscarriage as a significant psychosocial stressor that results in a high level of dysphoria and grief. Anxiety, although also commonly present, is less frequently considered and less frequently addressed. A review of the empirical literature was conducted to determine if anxiety after a miscarriage is elevated, and if risk is increased for particular types of anxiety syndromes. An attempt was also made to identify the types of interventions that have been found to be helpful in alleviating anxiety. An electronic search of the Medline and Psych Info databases were conducted using the keywords "miscarriage," "perinatal loss," "pregnancy loss," "anxiety," "trauma," and "stress." The searches were not intentionally circumscribed by date. Further searches were then carried out using references. Studies were subsequently included only if most women in a study sample experienced the pregnancy loss before 20 weeks' gestation. The literature was relatively limited. With respect to level of anxiety after a miscarriage, 4 studies were located that employed a matched comparison group design, and 3 that employed a follow-up design. Three studies that used a matched comparison design were located with respect to an increased risk for particular anxiety syndromes. A significant percentage of women experience elevated levels of anxiety after a miscarriage up until about 6 months post-miscarriage, and they are at increased risk for obsessive-compulsive and posttraumatic stress disorder. Practitioners, as part of routine care after a miscarriage, should screen for signs of anxiety as well as depression. When signs of anxiety are present, opportunities for catharsis, understanding, and legitimation are likely to be helpful, as is reassurance that the stress is likely to appreciably lessen over the next 6 months.

To evaluate the predictive value of the progesterone level at the beta-human chorionic gonadotropin (β-hCG) check day for ongoing pregnancy maintenance in in vitro fertilization (IVF) cycles in women with previous unexplained repeated miscarriages. One hundred and forty-eight women, with visible gestational sac after IVF, were recruited in this observational study. All subjects had unexplained recurrent miscarriages in more than two previous IVF cycles. The progesterone level at the β-hCG check day (i.e. 14 days after oocyte retrieval) was assessed. The area under the curve (AUC) of the progesterone level was evaluated to predict the ongoing pregnancy or miscarriage outcomes. The overall ongoing pregnancy rate was 60.8% (90/148). The cut-off value with β-hCG levels higher than 126.5 mIU/mL and with progesterone levels higher than 25.2 ng/mL could be the predictive factors for ongoing pregnancy maintenance (AUC = 0.788 and 0.826; sensitivity = 0.788 and 0.723; specificity = 0.689 and 0.833; P < 0.0001 and P < 0.0001, respectively). The miscarriage rates were 19.5% (15/77) in the women with β-hCG > 126.5 mIU/mL and 13.0% (10/77) in those with > 25.2 ng/mL. In the comparison of the ROC curves between both values, a similar significance was found. The subjects with β-hCG > 126.5 mIU/mL and progesterone > 25.2 ng/mL showed higher ongoing pregnancy rates [98.0% (49/50) vs. 41.8% (41/98)] than those with β-hCG ≤ 126.5 mIU/mL or progesterone ≤ 25.2 ng/mL. The progesterone level at 14 days after oocyte retrieval can be a good predictive marker for ongoing pregnancy maintenance in women with repeated IVF failure with miscarriage, together with the β-hCG level. The combined cut-off value of progesterone > 25.2 ng/mL and β-hCG > 126.5 mIU/mL may suggest a good prognosis.

Is there a relationship between ovarian reserve, quantified as ovarian response to stimulation, and miscarriage rate following IVF treatment? There is a strong association between the number of oocytes retrieved and miscarriage rate following IVF treatment, with the miscarriage rate decreasing with an increasing number of oocytes and then levelling off: poor responders have a higher miscarriage rate across all age groups. Poor ovarian response is a manifestation of a decline in the quantity of the primordial follicle pool. Whether poor ovarian response is associated with a decline in oocyte quality contributing to miscarriage is however debated. Anonymous data were obtained from the Human Fertilization and Embryology Authority (HFEA), the statutory regulator of assisted reproduction treatment (ART) in the UK. The HFEA has collected data on all ART performed in the UK since 1991. Data from 1991 to June 2008 involving 402 185 stimulated fresh IVF cycles and 124 351 pregnancy outcomes were analysed. Data on all women undergoing a stimulated fresh IVF treatment cycle with at least one oocyte retrieved during the period from 1991 to June 2008 were analysed for their early pregnancy outcomes. There was a strong association between the number of oocytes retrieved and the clinical miscarriage rate. The miscarriage rate fell from 20 to 13% with an increasing number of oocytes before levelling off. Stepwise logistic regression identified three cut-off points (4, 10 and 15 oocytes) at or beyond which the probability of clinical miscarriage fell. There was no increase in miscarriage rate with very high oocyte numbers (>20 oocytes). The lowest risk of miscarriage (9.9%) was for women under 38 years of age, with primary infertility without a female cause and producing more than three oocytes. Although the analysis was performed only on stimulated IVF cycles (excluding unstimulated cycles), the data had the limitation that there was no information on the total gonadotrophin

Epidemiological studies of the long-term maternal health outcomes of spontaneous miscarriages have been sparse and inconsistent. The objective of our study is to examine the association between spontaneous miscarriages and diabetes among middle-aged and older Chinese women. A total of 19,539 women from the Dongfeng-Tongji cohort study who completed a questionnaire and had medical examinations performed on were included in the analysis. History of spontaneous miscarriage was obtained by self-reporting in the first follow-up questionnaire interview. The presence of diabetes was determined by a fasting plasma glucose level, self-reported physician diagnosis and use of antidiabetic medication. A series of multivariate logistic regression models were used to calculate the odds ratios and 95% CI across spontaneous miscarriage categories (0, 1, 2, ≥ 3) after adjustment for potential confounding factors. The prevalence rate of diabetes was 18.8% among the participants. In the fully adjusted logistic regression model, women who had 1, 2 or ≥ 3 spontaneous miscarriages had 0.86 times (95% CI 0.68, 1.08), 1.30 times (95% CI 0.82, 2.04) and 2.11 times (95% CI 1.08, 4.11) higher risk of diabetes, respectively, compared with women who had no history of spontaneous miscarriage. There is an increased risk of diabetes among women with a history of a higher number of spontaneous miscarriages. History of multiple spontaneous miscarriages should be taken into consideration when assessing the risk of diabetes.

Long term follow up of idiopathic gingival enlargement associated with chronic periodontitis: A case report and review

Background: Idiopathic gingival enlargement is a rare condition characterized by massive enlargement of the gingiva. It may be associated with other diseases/conditions characterizing a syndrome, but rarely associated with periodontitis. Case Description: This case report describes an unusual clinical form of gingival enlargement associated with chronic periodontitis. Clinical examination revealed diffuse gingival enlargement. The lesion was asymptomatic, firm, and pinkish red. Generalized periodontal pockets were observed. Radiographic evaluation revealed generalized severe alveolar bone loss. Histopathological investigations revealed atrophic epithelium with dense fibrocollagenous tissue. Lesions healed successfully following extraction and surgical excision, and no recurrence was observed after 1 year follow-up but recurrence was observed at 3 and 5-years follow-up. Clinical Implications: Successful treatment of idiopathic gingival enlargement depends on proper identification of etiologic factors and improving esthetics and function through surgical excision of the over growth. However, there may be recurrence. PMID:23869135

Recurrent pregnancy loss in patients with thyroid dysfunction.

PubMed

Sarkar, Debanjali

2012-12-01

Thyroid disturbances are common in women during their reproductive years. Thyroid dysfunction interferes with human reproductive physiology, reduces the likelihood of pregnancy and adversely affects pregnancy outcome, thus becoming relevant in the algorithm of reproductive dysfunction. This review highlights the gap in knowledge regarding the contribution of thyroid dysfunction in reproduction. Following implantation, the maintenance of the pregnancy is dependent on a multitude of endocrinological events that will eventually aid in the successful growth and development of the fetus. It is estimated that approximately 8-12% of all pregnancy losses are the result of endocrine factors. Autoimmune thyroid disease is present in around 4% of young females and up to 15% are at risk because they are thyroid antibody-positive. There is a strong relationship between thyroid immunity on one hand and infertility, miscarriage, and thyroid disturbances in pregnancy and postpartum, on the other hand. Even minimal hypothyroidism can increase rates of miscarriage and fetal death and may also have adverse effects on later cognitive development of the offspring. Hyperthyroidism during pregnancy may also have adverse consequences. Pregnant women with subclinical hypothyroidism or thyroid antibodies have an increased risk of complications, especially pre-eclampsia, perinatal mortality, and miscarriage. Universal screening for thyroid hormone abnormalities is not routinely recommended at present, but thyroid function must be examined in female with fetal loss or menstrual disturbances. Practitioners providing health care for women should be alert to thyroid disorders as an underlying etiology for recurrent pregnancy loss.

To assess pregnancy outcomes in women with threatened miscarriage in the first trimester. This was a retrospective cohort study based on data extracted from the Aberdeen Maternity and Neonatal Databank. Cases included all primigravid women with first-trimester vaginal bleeding who delivered after 24 weeks of gestation between 1976 and 2004. The control group comprised all other women who had first pregnancies during the same period. Data were analyzed by univariate and multivariate statistical methods. Compared with the control group (n = 31,633), women with threatened miscarriage (n = 7,627) were more likely to have antepartum hemorrhage of unknown origin (odds ratio [OR] 1.83, 95% confidence interval [CI] 1.73-2.01). Elective cesarean (OR 1.30, 95% CI 1.14-1.48) and manual removal of placenta (OR 1.40, 95% CI 1.21-1.62) were performed more frequently in these women, who also had a higher risk of preterm delivery (OR 1.56, 95% CI 1.43-1.71) and malpresentation (OR 1.26, 95% CI 1.13-1.40). Threatened miscarriage in the first trimester is required in 112, 112, 17, 85, 32 patients, respectively, for each additional case of manual removal of placenta, elective cesarean, antepartum hemorrhage of unknown origin, malpresentation, and preterm delivery. Pregnancies complicated by threatened miscarriage are at a slightly higher risk of obstetric complications and interventions. II-2.

Idiopathic granulomatous mastitis: case report and review of the literature.

We report a case of idiopathic granulomatous mastitis in a 35-year-old Japanese woman, who came to our hospital complaining of a tender mass in her right breast. Because the results of initial aspiration cytology were considered highly suspicious for carcinoma, modified radical mastectomy was performed. However, the final histological diagnosis was granulomatous lobular mastitis with no evidence of malignancy. Idiopathic granulomatous mastitis is a rare inflammatory breast disease of unknown etiology. Since the clinical manifestations are similar to those of mammary carcinoma, this condition has been misdiagnosed as carcinoma and treated as such. A review of the literature revealed that idiopathic granulomatous mastitis has tended to occur in young patients with a history of childbirth or oral contraceptive usage. Clinical or imaging diagnosis has often been difficult. Complete resection or corticosteroid therapy can be recommended as the optimal treatment. Since 38% of patients experience recurrence, long-term follow-up is indicated.

The antibiotic trimethoprim acts as a folate antagonist. Since trophoblasts are very sensitive to drugs that interfere with the folic acid cycle and thereby inhibit DNA synthesis, use of trimethoprim during the first trimester could be associated with miscarriage. A nationwide cohort study including all women in Denmark with a registered pregnancy between 1997 and 2005 was conducted. We used nationwide registers to identify all women giving birth, having a record of miscarriage or induced abortion. Data on exposure to trimethoprim were obtained from the National Prescription Register. Cox proportional hazard regression analysis with exposure to trimethoprim as a time-dependent variable was used to estimate the risk of miscarriage. The adjusted hazard ratio of having a miscarriage after exposure to trimethoprim in the first trimester compared to non-exposure was 2∙04 (95% confidence interval 1∙43-2∙91). Our results indicate that trimethoprim exposure in the first trimester is associated with a doubling of the hazard of miscarriage.

This paper deals with the psychic disorders that frequently follow miscarriages. We specify the clinical forms under which such disorders appear and argue in favour of establishing a "Post-Abortion Syndrome" which would include the symptoms that form the basis of the psychopathological reactions that follow miscarriages. We will also study the psychological and psychopathological reactions to be found in couples -in both men and women-, who undergo fertility treatments, offering a brief description of the psychodynamic aspects that affect the couple. Furthermore, we will stress the biological and psychological risks that appear as a consequence of fertility treatments and offer an ethical evaluation of these risks, warning of the long-term consequences of human reproductive techniques.

Galectins are galactose binding proteins and, in addition, factors for a wide range of pathologies in pregnancy. We have analyzed the expression of prototype (gal-1, -2, -7, -10) and chimera-type (gal-3) galectins in the placenta in cases of spontaneous abortions (SPA) and recurrent abortions (RA) in the first trimester. Fifteen placental samples from healthy pregnancies were used as a control group. Nine placentas were examined for spontaneous abortions, and 12 placentas for recurrent abortions. For differentiation and evaluation of different cell types of galectin-expression in the decidua, immunofluorescence was used. For all investigated prototype galectins (gal-1, -2, -7, -10) in SPA and RA placenta trophoblast cells the expression is significantly decreased. In the decidua/extravillous trophoblast only gal-2 expression was significantly lowered, which could be connected to its role in angiogenesis. In trophoblasts in first-trimester placentas and in cases of SPA and RA, prototype galectins are altered in the same way. We suspect prototype galectins have a similar function in placental tissue because of their common biochemical structure. Expression of galectin 3 as a chimera type galectin was not found to be significantly altered in abortive placentas.

In trophoblasts in first-trimester placentas and in cases of SPA and RA, prototype galectins are altered in the same way. We suspect prototype galectins have a similar function in placental tissue because of their common biochemical structure. Expression of galectin 3 as a chimera type galectin was not found to be significantly altered in abortive placentas. PMID:27136536

Maternal underweight, overweight and obesity have been associated with a higher risk of miscarriage. Most individual reports and all meta-analyses have addressed high body mass index. To review the literature and summarize the risk of miscarriage in underweight women vs those with normal weight. A Medline Search (1st January 1990-20th November 2015, human, in English, French, Italian, Spanish or Portuguese) was conducted. Both spontaneous pregnancies and pregnancies after assisted reproduction techniques were considered. Cohort and case control studies were included if they reported data on the outcome of interest (clinical miscarriage), in underweight and normal weight women. Information on clinical miscarriage in other body mass index categories was collected when available. Two investigators reviewed the abstracts, full text papers and extracted data. Review Manager 5.1 software was used to summarize the results. 32 studies (30 cohort, 2 case control) and a total of 265,760 women were included. In cohort studies, the relative risk (RR) of clinical miscarriage in underweight women was 1.08, 95% CI 1.05-1.11; p<0.0001). The corresponding figures were RR 1.09, 95% CI 1.04-1.13; p<0.0001 for overweight women and RR 1.21, 95% CI 1.15-1.27; p<0.00001 for obese women. In case control studies, the odds ratio (OR) of clinical miscarriage in underweight women was 1.02, 95% CI 0.46-2.30; p=0.95). The corresponding figures were OR 1.01, 95% CI 0.88-1.16; p=0.89 for overweight women and OR 1.26, 95% CI 1.01-1.57; p=0.04 for obese women. The limitations of this study are that it is restricted to studies with information on underweight women and that I 2 ranges from 0 to 91% in different subgroups. We conclude that maternal underweight is associated with a slightly increased risk of clinical miscarriage, similar to that of overweight women and lower than the risk observed in obesity. The heterogeneity displayed in some subgroups limits the strength of the conclusion. Copyright

Scrotal lymphedema (scrotal elephantiasis) is uncommon outside of filariasis endemic regions. We present a case of a 65-year-old with idiopathic lymphedema of the scrotum and functional impairment of the penis. The patient underwent surgical excision of the edematous subcutaneous tissues and plastic reconstruction of his penis and scrotum. Three years later, the patient showed no signs of local recurrence, had complete restoration of urinary and sexual function and was extremely satisfied with the result. Surgical management was an effective strategy in the management of scrotal lymphedema in this case.

Women with recurrent spontaneous pregnancy loss (RPLJ are in a complex scenario, due to the work-up evaLuation that is negative in about 50% of the cases, and the stress associated with the outcome of the next pregnancy. Therefore, these patients experience psychoLogicaL conditions including anxiety and depression. The basic examination includes: parental karyotype, anatomical evaluation of the uterus, hormonal profile (including TSH, prolactin level and glucose) and APLA evaLuation. In recent years, several changes had been reported in the recurrent pregnancy loss definition, the preferred mode of the uterine cavity evaluation and the need for anti-thrombotic treatment in idiopathic RPL. In addition, new concepts in the pathophysiology and the etiology of RPL have been described as well as the extent of the evaluation. It is important to emphasize that those women with RPL in general and those with idiopathic RPL specifically, will experience about a 75% live birth rate in the next pregnancy when they are in a specialized RPL clinic. In this review, we will discuss these issues according to the recent studies incLuding the evaluation and treatment that are implicated in the RPL clinic in the Soroka University Medical Center.

When mixed methods produce mixed results: integrating disparate findings about miscarriage and women's wellbeing.

To discuss an example of mixed methods in health psychology, involving separate quantitative and qualitative studies of women's mental health in relation to miscarriage, in which the two methods produced different but complementary results, and to consider ways in which the findings can be integrated. We describe two quantitative projects involving statistical analysis of data from 998 young women who had had miscarriages, and 8,083 who had not, across three waves of the Australian Longitudinal Study on Women's Health. We also describe a qualitative project involving thematic analysis of interviews with nine Australian women who had had miscarriages. The quantitative analyses indicate that the main differences between young women who do and do not experience miscarriage relate to social disadvantage (and thus likelihood of relatively early pregnancy) and to a lifestyle that makes pregnancy likely: Once these factors are accounted for, there are no differences in mental health. Further, longitudinal modelling demonstrates that women who have had miscarriages show a gradual increase in mental health over time, with the exception of women with prior diagnoses of anxiety, depression, or both. By contrast, qualitative analysis of the interviews indicates that women who have had miscarriages experience deep emotional responses and a long and difficult process of coming to terms with their loss. A contextual model of resilience provides a possible framework for understanding these apparently disparate results. Considering positive mental health as including the ability to deal constructively with negative life events, and consequent emotional distress, offers a model that distinguishes between poor mental health and the processes of coping with major life events. In the context of miscarriage, women's efforts to struggle with difficult emotions, and search for meaning, can be viewed as pathways to resilience rather than to psychological distress. Statement of contribution

Killer immunoglobulin-like receptors (KIRs) and HLA-C allorecognition patterns implicative of dominant activation of natural killer cells contribute to recurrent miscarriages.

PubMed

Faridi, R M; Agrawal, S

2011-02-01

Decidual natural killer (NK) cells play key developmental roles at the feto-maternal interface. Individual differences in NK-cell interactions are dependent on the combinations of variable killer immunoglobulin-like receptor (KIR) and HLA class-I gene products. As different receptor-ligand interactions may result in altered NK-cell-mediated immunity against pathogens, it is proposed that the relationship between these genes may be important in a state such as recurrent miscarriage (RM). We had earlier reported that the predisposition to RM is influenced by the maternal KIR gene content. In the present study, we have attempted to extend our findings in the light of contribution from the paternal antigens on the outcome of pregnancy, since maternal NK cells may potentially encounter non-self-paternal HLA-C alleles on trophoblasts. All HLA-C allotypes fall into two major KIR epitopes--C1 (HLA-C*01/*03/*07/*08/*12/*14/*16) and C2 (HLA-C*02/*04/*05/*06/*15/*17/*18)--on the basis of a dimorphism at position 80 of the α1 domain. PCR-sequence specific primer-based genotyping was used to determine the maternal KIR gene content and HLA-C genotypes down to allele level in couples experiencing RM and controls. KIR2DL1 with both partners homozygous for HLA C2 was significantly higher in control couples when compared with the patients [P = 0.0004, odds ratio (OR) = 0.28, 95% confidence interval (CI) = 0.13-0.58]. The activating KIR2DS2 with both partners homozygous for HLA C1 was significantly higher in patients when compared with the controls (P = 0.002, OR = 2.83, 95% CI = 1.47-5.40). Our results represented the 'top-end' of the activation spectrum of KIR-HLA-C compound genotype for NK cells and this may contribute to the immunological etiology of RM.

The aim of this paper was to estimate the risk of miscarriage after amniocentesis or chorionic villus sampling (CVS) based on a systematic review of the literature. A search of Medline, Embase, and The Cochrane Library (2000-2017) was carried out to identify studies reporting complications following CVS or amniocentesis. The inclusion criteria for the systematic review were studies reporting results from large controlled studies (N.≥1000 invasive procedures) and those reporting data for pregnancy loss prior to 24 weeks' gestation. Data for cases that had invasive procedure and controls were inputted in contingency tables and risk of miscarriage was estimated for each study. Summary statistics were calculated after taking into account the weighting for each study included in the systematic review. Procedure-related risk of miscarriage was estimated as a weighted risk difference from the summary statistics for cases and controls. The electronic search from the databases yielded 2465 potential citations of which 2431 were excluded, leaving 34 studies for full-text review. The final review included 10 studies for amniocentesis and 6 studies for CVS, which were used to estimate risk of miscarriage in pregnancies that had an invasive procedure and the control pregnancies that did not. The procedure-related risk of miscarriage following amniocentesis was 0.35% (95% confidence interval [CI]: 0.07 to 0.63) and that following CVS was 0.35% (95% CI: -0.31 to 1.00). The procedure-related risks of miscarriage following amniocentesis and CVS are lower than currently quoted to women.

Tocopherols were discovered for their role in animal reproduction, but little is known about the contribution of deficiencies of vitamin E to human pregnancy loss. We sought to determine whether higher first-trimester concentrations of α-tocopherol and γ-tocopherol were associated with reduced odds of miscarriage (pregnancy losses <24 wk of gestation) in women in rural Bangladesh. A case-cohort study in 1605 pregnant Bangladeshi women [median (IQR) gestational age: 10 wk (8-13 wk)] who participated in a placebo-controlled vitamin A- or β-carotene-supplementation trial was done to assess ORs of miscarriage in women with low α-tocopherol (<12.0 μmol/L) and γ-tocopherol (<0.81 μmol/L; upper tertile cutoff of the γ-tocopherol distribution in women who did not miscarry). In all women, plasma α- and γ-tocopherol concentrations were low [median (IQR): 10.04 μmol/L (8.07-12.35 μmol/L) and 0.66 μmol/L (0.50-0.95 μmol/L), respectively]. In a logistic regression analysis that was adjusted for cholesterol and the other tocopherol, low α-tocopherol was associated with an OR of 1.83 (95% CI: 1.04, 3.20), whereas a low γ-tocopherol concentration was associated with an OR of 0.62 (95% CI: 0.41, 0.93) for miscarriage. Subgroup analyses revealed that opposing ORs were evident only in women with BMI (in kg/m(2)) ≥18.5 and serum ferritin concentration ≤150 μg/L, although low BMI and elevated ferritin conferred stronger risk of miscarriage. In pregnant women in rural Bangladesh, low plasma α-tocopherol was associated with increased risk of miscarriage, and low γ-tocopherol was associated with decreased risk of miscarriage. Maternal vitamin E status in the first trimester may influence risk of early pregnancy loss.

Objective To study idiopathic granulomatous mastitis with respect to its various clinical features, etiologic factors, treatment modalities and complications. Material and methods Retrospective study of all patients who were diagnosed with idiopathic granulomatous mastitis from 1st January 2006 to 31st December 2014 at Kasturba Hospital, Manipal, India (a tertiary care referral centre). The research was performed according to the World Medical Association Declaration of Helsinki. Informed consent was taken from the patient before invasive procedures including surgery. Data was analysed using the Statistical Package for Social Sciences version 16.0 wherever appropriate. Results 73 patients diagnosed with idiopathic granulomatous mastitis during the time period were included. One patient was a male (1.37%), rest were all females (98.63%). The mean age of presentation was 32.67 years (range 23 to 66 years). 70 patients (95.89%) were parous females. Average duration since last childbirth was 4.6 years (range: 3 months to 33 years). 8 patients (10.95%) were lactating. History of oral contraceptive pill use was present in 40 patients (54.79%). The right breast was affected in 44 patients (60.27%), and the left breast in 29 patients (39.73%). None of the patients had bilateral disease. The most common symptom was a painless lump (61.64%). Rest of the patients (38.36%) presented with features of a breast abscess. 19 out of 39 FNACs done (48.72%) were positive for granulomatous mastitis. 59 were primarily managed surgically (lumpectomy/wide excision-33, incision & drainage-26). One patient was treated primarily with prednisolone. 13 patients did not receive specific treatment, and were only kept on regular follow-up. Patients managed with lumpectomy/wide excision had the least rate of complications & recurrence (18.18%). Conclusion Patients with idiopathic granulomatous mastitis can present with a wide variety of symptoms which mimic other more common conditions. Surgical

Progesterone is essential to maintain a healthy pregnancy. Guidance from the Royal College of Obstetricians and Gynaecologists and a Cochrane review called for a definitive trial to test whether or not progesterone therapy in the first trimester could reduce the risk of miscarriage in women with a history of unexplained recurrent miscarriage (RM). The PROMISE trial was conducted to answer this question. A concurrent cost-effectiveness analysis was conducted. A randomised, double-blind, placebo-controlled, international multicentre study, with economic evaluation, conducted in hospital settings across the UK (36 sites) and in the Netherlands (nine sites). Women with unexplained RM (three or more first-trimester losses), aged between 18 and 39 years at randomisation, conceiving naturally and giving informed consent, received either micronised progesterone (Utrogestan(®), Besins Healthcare) at a dose of 400 mg (two vaginal capsules of 200 mg) or placebo vaginal capsules twice daily, administered vaginally from soon after a positive urinary pregnancy test (and no later than 6 weeks of gestation) until 12 completed weeks of gestation (or earlier if the pregnancy ended before 12 weeks). Live birth beyond 24 completed weeks of gestation (primary outcome), clinical pregnancy at 6-8 weeks, ongoing pregnancy at 12 weeks, miscarriage, gestation at delivery, neonatal survival at 28 days of life, congenital abnormalities and resource use. Participants were randomised after confirmation of pregnancy. Randomisation was performed online via a secure internet facility. Data were collected on four occasions of outcome assessment after randomisation, up to 28 days after birth. A total of 1568 participants were screened for eligibility. Of the 836 women randomised between 2010 and 2013, 404 received progesterone and 432 received placebo. The baseline data (age, body mass index, maternal ethnicity, smoking status and parity) of the participants were comparable in the two arms of

To describe 2 topographic facial pain conditions with the pain clearly localized in the eye (idiopathic ophthalmodynia) or in the nose (idiopathic rhinalgia), and to propose their distinction from persistent idiopathic facial pain. Persistent idiopathic facial pain, burning mouth syndrome, atypical odontalgia, and facial arthromyalgia are idiopathic facial pain syndromes that have been separated according to topographical criteria. Still, some other facial pain syndromes might have been veiled under the broad term of persistent idiopathic facial pain. Through a 10-year period we have studied all patients referred to our neurological clinic because of facial pain of unknown etiology that might deviate from all well-characterized facial pain syndromes. In a group of patients we have identified 2 consistent clinical pictures with pain precisely located either in the eye (n=11) or in the nose (n=7). Clinical features resembled those of other localized idiopathic facial syndromes, the key differences relying on the topographic distribution of the pain. Both idiopathic ophthalmodynia and idiopathic rhinalgia seem specific pain syndromes with a distinctive location, and may deserve a nosologic status just as other focal pain syndromes of the face. Whether all such focal syndromes are topographic variants of persistent idiopathic facial pain or independent disorders remains a controversial issue.

Recurrent chronic idiopathic urticaria (RCIU) is a common skin condition that affects 0.1-3% of the population in the USA and Europe and accounts for nearly 75% of all 'ordinary' chronic urticaria (CU) cases. We studied 838 consecutive patients with RCIU referred to hospital between 1998 and 2003. Patients with known causes of CU were excluded. Clinical history, physical examination, and symptom diaries were evaluated during two periods, a diet-free period (1 week) and a food-additive-free diet (FAFD) period (4 weeks), respectively, and two double-blind placebo-controlled (DBPC) challenges of six food additives were administered. The first DBPC challenge included a mixture of the six food additives (DBPCmixed) given to all patients. The second DBPC challenge comprised the single food additives, administered at increasing doses (DBPCsingle) to patients with a positive DBPCmixed test and 105 patients with a negative DBPCmixed test, as a control. The DBPCmixed challenge was positive in 116 patients. None of the 105 control patients had a positive DBPCsingle test. Only 31 DBPCsingle tests were positive in patients with positive DBPCmixed challenge. Twenty-four of the 116 patients showing a positive DBPCmixed challenge also had a positive DBPCsingle result. Our results confirmed that food additive hypersensitivity reactions occurred in few RCIU patients using DBPCsingle challenge. The combination of the results of FAFD and DBPCmixed challenge seems to be of considerable practical interest for allergists, internists and dermatologists, rather than the data of clinical history and the results of DBPCsingle challenge, in patients with RCIU.

Placental oxidative stress has been involved in the pathogenesis of certain reproductive adverse effects, including miscarriage. Paraxonase 1 (PON1) is a high-density lipoprotein(HDL)-linked enzyme that prevents oxidation of low-density lipoproteins (LDL) and is involved in detoxification from organophosphate pesticides. To assess the association between maternal PON1 polymorphisms (PON1192Q/R, PON155 L/M y PON1-108C/T) and the risk of miscarriage in women chronically exposed to organophosphate pesticides in Mexico. In a cross-sectional study, socio-demographic data, reproductive history data, environmental exposures, and other variables of concern were collected by means of a questionnaire from 264 women (floriculturists and wives of floriculturists) who had been pregnant sometime during the 10 years preceding the study. Blood samples were also collected from them. PON1192 and PON155 genotypes were determined by PCR amplification, and PON1-108 genotypes, by a TaqMan real-time polymerase chain reaction assay. Complete information regarding the results of pregnancy and maternal genotype tests was obtained for 514 pregnancies (35 miscarriages and 479 controls). The association between PON1 genotypes and miscarriage was evaluate through GEE models. The risk of miscarriage by mothers with PON1192RR genotype was 2.2 higher than by mothers with PON1192QR/PON1192QQ genotype (95% CI 0.93-5.17). The risk was close to 4 times higher in mothers with PON155MM/PON155LM genotype than in mothers with PON155LL genotype (OR=3.9; 95% CI 1.38-11.0). No significant differences were found in risk of miscarriage based on the maternal PON1-108C/T genotype. No evidence was found of an interaction between the various PON1 genotypes and the mothers' floricultural activity during pregnancy. This study suggests that there is an effect of genetic maternal PON1 polymorphisms on miscarriage and provides additional evidence that combines with the growing information about the ways in which

Recurrence and Treatment after Renal Transplantation in Children with FSGS

Ha, Il-Soo

2016-01-01

Focal segmental glomerulosclerosis (FSGS) is a common cause of end-stage renal disease and a common pathologic diagnosis of idiopathic nephrotic syndrome (NS), especially in steroid-resistant cases. FSGS is known to recur after kidney transplantation, frequently followed by graft loss. However, not all patients with FSGS suffer from recurrence after kidney transplantation, and genetic and secondary FSGS have a negligible risk of recurrence. Furthermore, many cases of recurrence achieve remission with the current management of recurrence (intensive plasmapheresis/immunosuppression, including rituximab), and other promising agents are being evaluated. Therefore, a pathologic diagnosis of FSGS itself should not cause postponement of allograft kidney transplantation. For patients with a high risk of recurrence who presented with classical symptoms of NS, that is, severe edema, proteinuria, and hypoalbuminemia, close monitoring of proteinuria is necessary, followed by immediate, intensive treatment for recurrence.

To assess the effectiveness of supportive counselling after miscarriage. Randomised controlled trial. University hospital. Two hundred and eighty women with miscarriage. Women were randomised to receive supportive counselling from a nurse (at diagnosis and 2 weeks later) or routine care. Psychological wellbeing was measured with the General Health Questionnaire (GHQ-12) and Beck Depression Inventory (BDI). Primary outcome measured the proportion of women suffering psychological distress (GHQ-12 score ≥4) at 3 months after miscarriage. Secondary outcomes were GHQ-12 and BDI scores at 6 weeks, 3 and 6 months. There was no difference in the proportion of women suffering psychological distress at 3 months after miscarriage (17.1% in counselling group versus 24.4% in control group; 95% CI -0.034 to 0.177; P = 0.19). However, for the subgroup of women (n = 152) with high baseline GHQ-12 scores, the median GHQ-12 score in the counselling group was significantly lower than the control group at 6 weeks (median score 3 versus 4.5 in counselling and control groups; P = 0.04) and 3 months (median score 1 versus 2.5 in counselling and control groups; P = 0.03). Similarly, for women with high baseline BDI scores (BDI > 12), the proportion for women continuing to score high was significantly lower in the counselling group 6 weeks after miscarriage (33.3 versus 61.1% in counselling group and control group; P = 0.03). Although the results of current study do not justify routine counselling of all women following miscarriage, a supportive counselling programme for selected women with high levels of psychological distress is promising and merits further investigation. © 2014 Royal College of Obstetricians and Gynaecologists.

Effect of miscarriage history on maternal-infant bonding during the first year postpartum in the First Baby Study: a longitudinal cohort study

PubMed Central

2014-01-01

Background Miscarriage, the unexpected loss of pregnancy before 20 weeks gestation, may have a negative effect on a mother’s perception of herself as a capable woman and on her emotional health when she is pregnant again subsequent to the miscarriage. As such, a mother with a history of miscarriage may be at greater risk for difficulties navigating the process of becoming a mother and achieving positive maternal-infant bonding with an infant born subsequent to the loss. The aim of this study was to examine the effect of miscarriage history on maternal-infant bonding after the birth of a healthy infant to test the hypothesis that women with a history of miscarriage have decreased maternal-infant bonding compared to women without a history of miscarriage. Methods We completed secondary analysis of the First Baby Study, a longitudinal cohort study, to examine the effect of a history of miscarriage on maternal-infant bonding at 1 month, 6 months, and 12 months after women experienced the birth of their first live-born baby. In a sample of 2798 women living in Pennsylvania, USA, we tested our hypothesis using linear regression analysis of Shortened Postpartum Bonding Questionnaire (S-PBQ) scores, followed by longitudinal analysis using a generalized estimating equations model with repeated measures. Results We found that women with a history of miscarriage had similar S-PBQ scores as women without a history of miscarriage at each of the three postpartum time points. Likewise, longitudinal analysis revealed no difference in the pattern of maternal-infant bonding scores between women with and without a history of miscarriage. Conclusions Women in the First Baby Study with a history of miscarriage did not differ from women without a history of miscarriage in their reported level of bonding with their subsequently born infants. It is important for clinicians to recognize that even though some women may experience impaired bonding related to a history of miscarriage

Marston, Alexander P; Maldonado, Francisco J; Ravi, Karthik; Kasperbauer, Jan L; Ekbom, Dale C

To compare swallowing outcomes following cricopharyngeal (CP) dilation versus surgical myotomy in patients with dysphagia secondary to idiopathic CP bar. All patients had an idiopathic CP bar without a history of Zenker's diverticulum, head and neck cancer, or systemic neurologic disease treated between 2000 and 2013. The Functional Outcome Swallowing Scale (FOSS) was utilized to assess dysphagia symptoms. Twenty-three patients underwent 46 dilations and 20 patients had a myotomy. Nineteen of 23 (83%) patients in the dilation group and all patients in the myotomy group reported improved swallow function. The median difference in pre- versus post-intervention FOSS scores was not statistically significant (p=0.07) between the dilation and myotomy groups with mean reductions of 1.3 and 1.8, respectively. Seventeen of 23 (74%) dilation patients had persistent or recurrent dysphagia with 13 (57%) requiring repeat dilation and 4 (17%) undergoing CP myotomy. The median time to first reintervention in the dilation group was 13.6months. Nineteen of 20 (95%) surgical myotomy patients did not experience recurrent dysphagia. Both endoscopic CP dilation and myotomy led to similar initial improvement in swallow function for patients with primary idiopathic CP bar; however, dilation is more likely to provide temporary benefit.

Chung, Chen-Shuan; Chiang, Tsung-Hsien; Lee, Yi-Chia

2015-01-01

An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.

Recurrent pericarditis is the most troublesome complication of pericarditis occurring in 15 to 30% of cases. The pathogenesis is often presumed to be immune-mediated although a specific rheumatologic diagnosis is commonly difficult to find. The clinical diagnosis is based on recurrent pericarditis chest pain and additional objective evidence of disease activity (e.g. pericardial rub, ECG changes, pericardial effusion, elevation of markers of inflammation, and/or imaging evidence of pericardial inflammation by CT or cardiac MR). The mainstay of medical therapy for recurrent pericarditis is aspirin or a non-steroidal anti-inflammatory drug (NSAID) plus colchicine. Second-line therapy is considered after failure of such treatments and it is generally based on low to moderate doses of corticosteroids (e.g. prednisone 0.2 to 0.5 mg/kg/day or equivalent) plus colchicine. More difficult cases are treated with combination of aspirin or NSAID, colchicine and corticosteroids. Refractory cases are managed by alternative medical options, including azathioprine, or intravenous human immunoglobulins or biological agents (e.g. anakinra). When all medical therapies fail, the last option may be surgical by pericardiectomy to be recommended in well-experienced centres. Despite a significant impairment of the quality of life, the most common forms of recurrent pericarditis (usually named as "idiopathic recurrent pericarditis" since without a well-defined etiological diagnosis) have good long-term outcomes with a negligible risk of developing constriction and rarely cardiac tamponade during follow-up. The present article reviews current knowledge on the definition, diagnosis, aetiology, therapy and prognosis of recurrent pericarditis with a focus on the more recent available literature.

Couples' grief and experience of support in the aftermath of miscarriage.

PubMed

Conway, K; Russell, G

2000-12-01

The aim of this prospective study involving 39 women and 32 partners was to investigate the grief response of both the woman and her partner to miscarriage and to ascertain if support received was adequate and appropriate to their needs. Previous research shows that partners' grief can often be delayed and chronic. Special emphasis is placed on this area in this study. The miscarriage was found to be a significant event and the majority of women and partners still experienced feelings of loss up to 4 months afterwards, describing their reactions as sad or very sad. Scores on the first administration of the Perinatal Grief Scale showed that, in contrast with previous findings, partners scored significantly higher than the women on the three subscales and overall. Partners' scores on the second administration were also higher than those for the women but the difference was not significant. The women tended to receive and welcome social support more than the partners. Support received from health professionals was not always optimal, particularly for partners. Pregnancy subsequent to miscarriage was often viewed with some anxiety. It is argued that the results of the study have important implications for health practice.

2008-03-01

The objective of the study was to identify correlates of perceived risk of carrying a Down syndrome-affected fetus or experiencing a procedure-related miscarriage among a diverse group of pregnant women. We conducted a cross-sectional survey of 1081 English-, Spanish-, or Chinese-speaking women receiving prenatal care in the San Francisco Bay area. Perceived risk of procedure-related miscarriage or carrying a Down syndrome-affected fetus was assessed using a linear rating scale from 0 (no risk) to 1 (high risk). Bivariate and multivariable analyses were used to explore associations between maternal characteristics including age, race/ethnicity, and socioeconomic status and perceived risks of carrying a Down syndrome-affected fetus or experiencing a procedure-related miscarriage. Women aged 35 years old or older had a higher perceived risk of Down syndrome than younger women (0.28 vs 0.22 on a scale from 0 to 1, P < .001) but a lower perceived risk of a procedure-related miscarriage (0.31 vs 0.36, P = .004). In multivariable linear regression analysis among women younger than age 35 years, the perceived risk of carrying a Down syndrome-affected fetus was higher in women who had not attended college (+0.06, P = .019) or had poor self-perceived health status (+0.08, P = .045). Latinas (+0.11, P = .008), women with an annual income less than $35,000 (+0.09, P = .003), and those who had difficulty conceiving (+0.09, P = .026) had higher perceived procedure-related miscarriage risk. Among women aged 35 years or older, perceived risk of carrying a Down syndrome-affected fetus was associated with the inclination to undergo prenatal diagnosis. Women's perceived risks of carrying a Down syndrome-affected fetus or having a procedure-related miscarriage are associated with numerous characteristics that have not been shown to be associated with the actual risks of these events. These perceived risks are associated with prenatal diagnostic test inclination. Understanding

The purpose of this study was to evaluate circulating and intracellular levels of Th1 and Th2 cytokines in women with threatened miscarriage (TM) and subsequent outcome. Plasma levels of tumor necrosis factor (TNF)-receptors 1 and 2, TNFα, interferon gamma (IFNγ), and interleukins (IL) -6 and -10 were measured by flow cytometric bead assays in 80 women with TM: 53 women with normal outcome and 27 women who miscarried. Fluorescent antibody labeling was also performed on whole blood in a subgroup of 27 women of TM: 16 women with normal outcome and 11 women who miscarried. Monocyte expression of TNFα and circulating levels of TNFα, IFNγ, IL-10, IL-6, and TNF-R1 were significantly lower, whereas circulating levels of TNFα/IL-10, IFNγ/IL-10, and TNFα/IL-6 ratios were significantly higher, in women with TM who subsequently miscarried, compared with the women with normal outcome. An increased Th1 type of immune response, which was similar to that observed in preterm delivery, was found in TM cases that were complicated by a subsequent miscarriage. Copyright © 2011.

Herpes simplex virus type 2-associated recurrent aseptic (Mollaret's) meningitis in genitourinary medicine clinic: a case report.

PubMed

Abou-Foul, Ahmad K; Buhary, Thajunisha M; Gayed, Sedki L

2014-01-01

Cases of idiopathic recurrent benign aseptic meningitis were first described by Mollaret. Today, herpes simplex virus (HSV) is considered the cause of most cases of Mollaret's meningitis. A 40-year-old male was referred to our genitourinary medicine clinic with recurrent genital herpetic lesions. He had HSV-2-positive genital ulcers 8 years earlier. One year after the first infection, he developed severe recurrent attacks of headache associated with meningitis symptoms. The results of all radiological and biochemical tests were normal, but the patient reported a correlation between his attacks and genital herpes flare-ups. We diagnosed the patient with Mollaret's meningitis and started him on continuous suppressive acyclovir therapy, which resulted in marked clinical improvement. Mollaret's meningitis is a rare form of idiopathic recurrent aseptic meningitis that has a sudden onset, short duration, and spontaneous remission with unpredictable recurrence. We believe that the presence of concurrent or recurrent mucocutaneous herpetic lesions can aid its diagnosis, prior to which, affected patients usually have many unnecessary investigations and treatments. Therefore, detailed sexual history should be sought in all patients with aseptic meningitis, and clinicians should also ask about history of recurrent headaches in all patients with recurrent herpetic anogenital lesions. Continuous suppressive acyclovir therapy may reduce the frequency and severity of attacks and can dramatically improve lifestyle.

Recurrent pericarditis: new and emerging therapeutic options.

Imazio, Massimo; Lazaros, George; Brucato, Antonio; Gaita, Fiorenzo

2016-02-01

Recurrent pericarditis is one of the most common and troublesome complications after an episode of pericarditis, and affects 20-50% of patients treated for pericarditis. In most of these patients, the pericarditis remains idiopathic, although an immune-mediated (either autoimmune or autoinflammatory) pathogenesis is often presumed. The mainstay of therapy for recurrences is aspirin or NSAIDs, with the adjunct of colchicine. Corticosteroids are a second-line option to be considered for specific indications, such as connective tissue disease or pregnancy; contraindications or intolerance to aspirin, NSAIDs, and/or colchicine; or insufficient response to these medications. Furthermore, corticosteroids can be added to NSAIDs and colchicine in patients with persistent symptoms. In patients who do not respond adequately to any of these conventional therapies, alternative treatment options include azathioprine, intravenous human immunoglobulins, and anakinra. An improved understanding of how recurrent pericarditis develops after an initiating event is critical to prevent this complication, and further research is needed into the pathogenesis of recurrences. We discuss the aetiology and diagnosis of recurrent pericarditis, and extensively review the treatment options for this condition.

To estimate procedure-related risks of miscarriage following amniocentesis and chorionic villus sampling (CVS) based on a systematic review of the literature and a meta-analysis. A search of MEDLINE, EMBASE, CINHAL and The Cochrane Library (2000-2014) was performed to review relevant citations reporting procedure-related complications of amniocentesis and CVS. Only studies reporting data on more than 1000 procedures were included in this review to minimize the effect of bias from smaller studies. Heterogeneity between studies was estimated using Cochran's Q, the I(2) statistic and Egger bias. Meta-analysis of proportions was used to derive weighted pooled estimates for the risk of miscarriage before 24 weeks' gestation. Incidence-rate difference meta-analysis was used to estimate pooled procedure-related risks. The weighted pooled risks of miscarriage following invasive procedures were estimated from analysis of controlled studies including 324 losses in 42 716 women who underwent amniocentesis and 207 losses in 8899 women who underwent CVS. The risk of miscarriage prior to 24 weeks in women who underwent amniocentesis and CVS was 0.81% (95% CI, 0.58-1.08%) and 2.18% (95% CI, 1.61-2.82%), respectively. The background rates of miscarriage in women from the control group that did not undergo any procedures were 0.67% (95% CI, 0.46-0.91%) for amniocentesis and 1.79% (95% CI, 0.61-3.58%) for CVS. The weighted pooled procedure-related risks of miscarriage for amniocentesis and CVS were 0.11% (95% CI, -0.04 to 0.26%) and 0.22% (95% CI, -0.71 to 1.16%), respectively. The procedure-related risks of miscarriage following amniocentesis and CVS are much lower than are currently quoted. Copyright © 2014 ISUOG. Published by John Wiley & Sons Ltd.

The role of oxidative stress in spontaneous abortion and recurrent pregnancy loss: a systematic review.

Human reproduction is not considered a highly efficient biological process. Before the end of the first trimester, 30%-50% of conceptions end in spontaneous abortion. Most losses occur at the time of implantation. 15%-20% of clinical pregnancies end in spontaneous abortions. Recurrent pregnancy loss is a frustrating clinical problem both for clinicians and patients. Recurrent pregnancy loss affects 0.5%-3% of women in the reproductive age group, and between 50%-60% of recurrent pregnancy losses are idiopathic. Oxidative stress-induced damage has been hypothesized to play a role in spontaneous abortion, idiopathic recurrent pregnancy loss, hydatidiform mole, defective embryogenesis, and drug-induced teratogenicity. Some studies implicate systemic and placental oxidative stress in the pathophysiology of abortion and recurrent pregnancy loss. Oxidant-induced endothelial damage, impaired placental vascularization and immune malfunction have all been proposed to play a role in the pathophysiology of idiopathic recurrent pregnancy loss. Oxidative stress-induced placental dysfunction may be a common cause of the multifactorial and polygenic etiologies of abortion, recurrent pregnancy loss, defective embryogenesis, hydatidiform mole, and drug-induced teratogenic effects. Oxidative stress-induced modification of phospholipids has been linked to the formation of antiphospholipid antibodies in the antiphospholipid syndrome. The objective of this review was to examine the association between oxidative stress, spontaneous abortion and recurrent pregnancy loss, based on the published literature. We conducted an extensive literature search utilizing the databases of Medline, CINAHL, and Cochrane from 1986 to 2005. The following keywords were used: oxidative stress, abortion, recurrent pregnancy loss, reactive oxygen species, antioxidants, fetal development, and embryopathies. We conducted an electronic search, as well as a manual search of cross-references. We have included all

Adjustment after miscarriage: Predicting positive mental health trajectories among young Australian women.

2010-01-01

Understanding predictors of adjustment after miscarriage can assist in the development of supportive interventions. This article uses data from three waves of the Younger Cohort of the Australian Longitudinal Study on Women's Health (1996, 2000, 2003) to examine predictors of positive Mental Health trajectories among 998 women who had experienced miscarriages. Using the five-item Mental Health subscale of the SF-36 (MHI-5) as an outcome, a multilevel model of change showed a general positive trend in Mental Health over time; also, higher education and satisfaction with the primary care physician were associated with higher Mental Health scores at each survey. After adjusting for sociodemographic factors, stress and negative life events were negatively associated with Mental Health. A history of medically diagnosed depression or anxiety was a significant predictor of change in Mental Health across the surveys, with women with such a history showing downward trajectories in Mental Health over time. The data suggest that greater targeted support and monitoring for women who have a history of mental health problems may assist those women to cope following miscarriage.

Objective The hypothesis of whether exposure to extremely low-frequency magnetic fields (ELF-MF) may increase miscarriage risk is controversial. A 2-year prospective cohort study was designed to study the association between exposure to 50 Hz magnetic fields (MF) and the miscarriage risk for women residing in the area of the Pearl-River Delta of China. Method Two towns with densely distributed power supply constructions were selected as the study sites. From 2010 to 2012, 552 women in the region who were at approximately 8 weeks of gestation or who planned to have a baby within 1 year were selected as candidate subjects. Exposure to MF was estimated by measurements at their front doors and in the alley in front of the subjects’ houses. The average exposure level was used as a cutoff point to define the exposed group. Clinical miscarriage was diagnosed by local obstetricians. Staffs from the local population and family planning service stations were responsible for the follow-up interviews every 2 months. Results Four hundred and thirteen pregnant women were selected for the cohort study. The average residential exposure to MF was 0.099 µT. No significantly increased risk of miscarriage was found to be associated with the average front-door exposure (p>0.05). However, miscarriage risk was found to be significantly associated with maximum alley exposure (p=0.001). The relative risk (RR) of miscarriage from maximum alley exposure was 2.35 (95% C.I.: 1.18-4.71). In addition, Cox regression analysis showed that the adjusted hazard ratio of maximum alley exposure for miscarriage was 1.72 (95% C.I.:1.10-2.69). Conclusion Although the miscarriage incidence was shown to be positively associated with the maximum alley MF exposure, the association between miscarriage risk and the exposure to MF was not confirmed in the study. The results of this study are of interest concerning MF exposure assessment and pregnancy outcomes. PMID:24312633

OBJECTIVES. We tested whether and under what conditions miscarriage increases depressive symptoms in the early weeks following loss. METHODS. We interviewed 232 women within 4 weeks of miscarriage and 283 pregnant women and 318 community women who had not recently been pregnant. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression (CES-D) Scale. RESULTS. Among women who had miscarried, the proportion who were highly symptomatic on the CES-D was 3.4 times that of pregnant women and 4.3 times that of community women. Among childless women, the proportion of women who had miscarried who were highly symptomatic was 5.7 times that of pregnant women and 11.0 times that of community women. Women who had miscarried were equally depressed regardless of length of gestation; among pregnant women, depressive symptoms declined with length of gestation. Among women who had miscarried, symptom levels did not vary with attitude toward the pregnancy; among pregnant women, depressive symptoms were elevated in those with unwanted pregnancies. Prior reproductive loss and advanced maternal age (35+ years) were not associated with symptom levels in any cohort. CONCLUSIONS. Depressive symptoms are markedly increased in the early weeks following miscarriage. This effect is substantially modified by number of living children, length of gestation at loss, and attitude toward pregnancy. PMID:1415855

Reproductive failure including RM has been suggested to correlate with antibodies that cross react with HLA-negative syncytiotrophoblasts and we have reported that 17% of women with 2 or more miscarriages and 34% of women with 3 or more miscarriages express anti-trophoblast antibodies (ATAB). Until now, the mechanism, how ATAB interfere with pregnancy success is not known. HCG and progesterone both play fundamental roles in supporting human pregnancy. Therefore we investigated the effects of sera of RM patients containing ATAB on the hCG and progesterone production of cells of the choriocarcinoma cell line JEG-3. In vitro study to investigate effects of patient sera with and without ATAB on hCG and progesterone secretion of JEG-3 cells. The presence of ATAB was detected as described earlier. Effects of sera from ATAB positive and ATAB negative RM patients on hCG and progesterone secretion by JEG-3 cells were analysed 12 and 24h after plating. Sera of women without pregnancy pathologies served as controls. Sera of ATAB-positive RM patients significantly inhibit hCG secretion of JEG-3 cells for 12h after plating compared to sera of healthy controls (p=0.019) and significantly reduce progesterone production for 12h (p=0.046) and 24h (p=0.027) of co-culture. Sera of ATAB-negative RM patient show no significant effect on progesterone secretion. Inhibition of hCG and progesterone production might point to a mechanism, how ATAB interfere with early pregnancies. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

A retrospective population-based study of primigravid women on the potential effect of threatened miscarriage on obstetric outcome.

Mulik, Varsha; Bethel, Jackie; Bhal, K

2004-04-01

The aim of this study was to ascertain any potential link between threatened miscarriage and obstetric outcome. Threatened miscarriage was associated independently with an increased incidence of abruption (OR 2.8, 2.0-3.7), unexplained antepartum haemorrhage (APH) (OR 2.3, 1.1-5.1) and preterm delivery (OR 2.0, 1.3-3.3). The incidence of low and very low birth weight deliveries, although significantly higher compared with the control population, was not affected independently by this early pregnancy complication on logistic regression (OR 1.3, 0.8-1.9). The early neonatal mortality rates were significantly higher in the threatened miscarriage group, which on logistic regression was due independently to preterm delivery, placental abruption and low birth weight deliveries. All forms of APH were significantly higher in term deliveries complicated by threatened miscarriage. Pregnancies presenting with threatened miscarriage should be highlighted as 'high risk' for a suboptimal obstetric outcome and a prospective observational trial followed by a randomised-controlled trial may be needed to establish whether the need exists for increased feto-maternal surveillance in this cohort of women.

The transcobalamin II (TCN2) 776C>G polymorphism has been reported to be a genetic risk factor for idiopathic recurrent spontaneous abortion (RSA). However, the sample size in previous studies was small, and other TCN2 polymorphisms have not been studied. Moreover, the TCN2 67A>G and 776C>G polymorphisms, and the transcobalamin II receptor (TCblR/CD320) 1104C>T polymorphism, have demonstrated associations with immune responses. Three hundred and seventy-eight RSA patients who had at least two consecutive spontaneous abortions were enrolled. Two hundred and seven control subjects were collected from a convenience sample. Polymerase chain reaction and restriction fragment length polymorphism analysis were performed to identify the TCN2 67A>G and 776C>G polymorphisms, and the TCblR 1104C>T polymorphism. RSA patients showed significantly different frequencies of the TCN2 67AG+GG genotypes compared with control subjects. The TCN2 67G allele is a possible risk factor for idiopathic RSA. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Decision analytic model comparing costs and clinical outcomes. Academic recurrent pregnancy loss programs. Women with unexplained RPL. IVF/PGS with 24-chromosome screening and expectant management. Cost per live birth. The IVF/PGS strategy had a live-birth rate of 53% and a clinical miscarriage rate of 7%. Expectant management had a live-birth rate of 67% and clinical miscarriage rate of 24%. The IVF/PGS strategy was 100-fold more expensive, costing $45,300 per live birth compared with $418 per live birth with expectant management. In this model, IVF/PGS was not a cost-effective strategy for increasing live birth. Furthermore, the live-birth rate with IVF/PGS needs to be 91% to be cost effective compared with expectant management. Copyright © 2015 American Society for Reproductive Medicine.

Perfluorinated alkylated substances (PFAS) have been extensively used in consumer products and humans are widely exposed to these persistent compounds. A recent study found no association between exposure to perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) and miscarriage, but no studies have examined adverse effect of the more recently introduced PFASs. We therefore conducted a case-control study within a population-based, prospective cohort during 2010-2012. Newly pregnant women residing in the Municipality of Odense, Denmark were invited to enroll in the Odense Child Cohort at their first antenatal visit before pregnancy week 12. Among a total of 2,874 participating women, 88 suffered a miscarriage and 59 had stored serum samples, of which 56 occurred before gestational week 12. They were compared to a random sample (N=336) of delivering women, who had also donated serum samples before week 12. Using a case-control design, 51 of the women suffering a miscarriage were matched on parity and gestational day of serum sampling with 204 delivering women. In a multiple logistic regression with adjustment for age, BMI, parity and gestational age at serum sampling, women with the highest tertile of exposure to perfluorononanoic acid (PFNA) and perfluorodecanoic acid (PFDA) in pregnancy had odds ratios for miscarriage of 16.5 (95% CI 7.4-36.6-36.5) and 2.67 (1.31-5.44), respectively, as compared to the lowest tertile. In the matched data set, the OR were 37.9 (9.9-145.2) and 3.71 (1.60-8.60), respectively. The association with perfluorohexane sulfonic acid (PFHxS) was in the same direction, but not statistically significant, while no association was found with PFOA and PFOS. Our findings require confirmation due to the possible public health importance, given that all pregnant women are exposed to these widely used compounds. PMID:25848775

To explore pregnancy outcomes in women following an initial miscarriage. Retrospective Cohort Study. Aberdeen Maternity Hospital, Aberdeen, Scotland. All women living in the Grampian region of Scotland with a pregnancy recorded in the Aberdeen Maternity and Neonatal Databank between 1986 and 2000. (A) Maternal outcomes: Pre-eclampsia, antepartum haemorrhage, threatened miscarriage, malpresenation, induced labour, instrumental delivery, Caesarean delivery, postpartum haemorrhage and manual removal of placenta. (B) Perinatal outcomes: preterm delivery, low birth weight, stillbirth, neonatal death, Apgar score at 5 minutes. Retrospective cohort study comparing women with a first pregnancy miscarriage with (a) women with one previous successful pregnancy and (b) primigravid women. Data were extracted on perinatal outcomes in all women from the Aberdeen Maternity and Neonatal Databank between 1986 and 2000. We identified 1561 women who had a first miscarriage (1404 in the first trimester and 157 in the second trimester), 10 549 who had had a previous live birth (group A) and 21 118 primigravidae (group B). The miscarriage group faced a higher risk of pre-eclampsia (adj OR 3.3, 99% CI 2.6-4.6), threatened miscarriage (adj OR 1.7, 99% CI 1.5-2.0), induced labour (adj OR 2.2, 99% CI 1.9-2.5), instrumental delivery (adj OR 5.9, 99% CI 5.0-6.9), preterm delivery (adj OR 2.1, 99% CI 1.6-2.8) and low birthweight (adj OR 1.6, 99% CI 1.3-2.1) than group A. They were more likely to have threatened miscarriage (adj OR 1.5, 99% CI 1.4-1.7), induced labour (adj OR 1.3, 99% CI 1.2-1.5), postpartum haemorrhage (adj OR 1.4, 99% CI 1.2-1.6) and preterm delivery (adj OR 1.5, 99% CI 1.2-1.8) than group B. An initial miscarriage is associated with a higher risk of obstetric complications.

In membranous nephropathy, the presence of antibodies against M-type phospholipase A2 receptor is considered highly specific for idiopathic forms. However, no specific association to a particular clinical profile has been found for such antibodies. To assess potential differences in initial clinical profile, course and prognosis of idiopathic membranous nephropathy depending on the presence of anti-PLA2R antibodies. Eighty-five patients with idiopathic membranous nephropathy were included (55 anti-PLA2R-positive and 30 anti-PLA2R-negative). Clinical, biochemical and pathological variables were recorded at the time of diagnosis. Frequency of spontaneous remission, incidence of response to first-line therapy, frequency and number of recurrences, survival of renal function free from renal replacement therapy, survival of renal function free from chronic renal insufficiency and frequency of occurrence of malignant, infectious or autoimmune diseases during follow-up were recorded. At the time of diagnosis, anti-PLA2R-negative patients were significantly older and had a higher frequency of spontaneous remission. No differences were noted in the response to first-line treatment, frequency and number of recurrences, survival of renal function free from renal replacement therapy, or survival of renal function free from chronic renal insufficiency. Anti-PLA2R-negative patients with idiopathic membranous nephropathy were older and experienced spontaneous remission more often than anti-PLA2R-positive patients. No differences in terms of treatment response, recurrences, and final prognosis were observed between both groups of patients. Copyright © 2015 The Authors. Published by Elsevier España, S.L.U.

Idiopathic anaphylaxis is a diagnosis of exclusion after other causes have been thoroughly evaluated and excluded. The pathogenesis of idiopathic anaphylaxis remains uncertain, although increased numbers of activated lymphocytes and circulating histamine-releasing factors have been implicated. Signs and symptoms of patients diagnosed with idiopathic anaphylaxis are indistinguishable from the manifestations of other forms of anaphylaxis. Treatment regimens are implemented based on the frequency and severity of patient symptoms and generally include the use of epinephrine autoinjectors, antihistamines, and steroids. The prognosis of idiopathic anaphylaxis is generally favorable with well-established treatment regimens and effective patient education. Copyright © 2015 Elsevier Inc. All rights reserved.

Objective To determine the optimum interpregnancy interval (IPI) following a miscarriage. Design Multivariate analysis of population-based, prospective data from a demographic surveillance system. Setting Pregnancies in Matlab, Bangladesh, between 1977 and 2008. Participants 9214 women with 10 453 pregnancies that ended in a miscarriage and were followed by another pregnancy outcome. Main outcome measures Outcome of pregnancy following the miscarriage was singleton live birth, stillbirth, miscarriage or induced abortion. For pregnancies that ended in live birth: early neonatal, late neonatal and postneonatal mortality. Results Compared with IPIs of 6–12 months, pregnancies that were conceived ≤3 months after a miscarriage were more likely to result in a live birth and less likely to result in a miscarriage (adjusted relative risk ratio (RRR) 0.70, 95% CI 0.57 to 0.86) or induced abortion (0.50, 0.29 to 0.89). Induced abortions were significantly more likely following IPIs of 18–24 months (2.36, 1.48 to 3.76), 36–48 months (2.73, 1.50 to 4.94), and >48 months (3.32, 1.68 to 2.95), and miscarriages were more likely following IPIs of 12–17 months (1.25, 1.01 to 1.56) and >48 months (1.90, 1.40 to 2.58). No significant effects of IPI duration are seen on the risks of a stillbirth. However, IPIs≤3 months following a miscarriage are associated with significantly higher late neonatal mortality for the infant born at the end of the IPI (adjusted hazard ratio (HR) 1.74, 1.06 to 2.84), and IPIs of 12–18 months are associated with a significantly lower unadjusted risk of postneonatal mortality (0.54, 0.30 to 0.96). Conclusions The shorter the IPI following a miscarriage, the more likely the subsequent pregnancy is to result in a live birth. However, very short IPIs may not be advisable following miscarriages in poor countries like Bangladesh because they are associated with a higher risk of mortality for the infants born after them.

To assess the relationship of the pre-pregnancy modifiable risks with miscarriage. We randomly selected 51 communities or villages from January 2013 to December 2014 in Anhui, China. We calculated incidence rate ratios (RR) and 95% confidence intervals (CIs) for each risk factor for miscarriage. The incidence rate of miscarriage was 7.45%, and pre-embryonic loss account for 12.66%, embryonic loss account for 38%, and fetal losses account for 49.34% of all loss. In multivariate analysis, women with hypertension (RR=2.272, 95% CI=1.27-4.04), women had a family history of abortion in their mother (RR=1.96, 95% CI=1.22-3.14) prior to pregnancy had significantly higher adjusted risk ratio for miscarriage. Obese, overweight, and underweight prior to pregnancy were about 2.01 (95% CI=1.1-3.68), 1.71 (95% CI=1.04-2.81), and 2.05 (95% CI=1.3-3.23) times more likely to end in miscarriage compared with normal weight. Some physical examination indicators, for example pH value of leucorrhea ≥4.5 (RR=2.13, 95% CI=1.48-3.07), red blood cell count <5 10(12)/L (RR=1.52, 95% CI=1.02-2.26), and positive LgG antibodies to human cytomegalovirus (RR=1.45, 95% CI=1.02-3.14) prior to pregnancy had good prediction effect on miscarriage. We also found remarkable differences on risk factors between non-fetal losses and fetal losses. Our results suggest that these modifiable risks should be included into pre-conception counseling as important risk factors for screening high-risk population and reducing the rate of spontaneous abortion.

To evaluate the effects on postoperative prognosis of internal limiting membrane (ILM) peeling in conjunction with removal of idiopathic epiretinal membranes (ERMs). MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE were systematically searched for studies that compared ILM peeling with no ILM peeling in surgery to remove idiopathic ERM. Outcome measures were best-corrected visual acuity, central macular thickness, and ERM recurrence. Studies that compared ILM peeling with no ILM peeling for the treatment of idiopathic ERM were selected. Sixteen studies that included 1,286 eyes were selected. All the included studies were retrospective or prospective comparative studies; no randomized controlled study was identified. Baseline preoperative best-corrected visual acuity and central macular thickness were equal between ILM peeling and no ILM peeling groups. Postoperatively, there was no statistically significant difference in best-corrected visual acuity (mean difference 0.01 logarithm of the minimum angle of resolution [equivalent to 0.5 Early Treatment Diabetic Retinopathy Study letter]; 95% CI -0.05 to 0.07 [-3.5 to 2.5 Early Treatment Diabetic Retinopathy Study letters]; P = 0.83) or central macular thickness (mean difference 13.13 μm; 95% CI -10.66 to 36.93; P = 0.28). However, the recurrence rate of ERM was significantly lower with ILM peeling than with no ILM peeling (odds ratio 0.25; 95% CI 0.12-0.49; P < 0.0001). Currently available evidence in the literature indicates that additional ILM peeling in vitrectomy for idiopathic ERM could result in a significantly lower ERM recurrence rate, but it does not significantly influence postoperative best-corrected visual acuity and central macular thickness.

2016-09-01

Recurrent pregnancy loss (RPL), commonly defined as 3 consecutive losses <10 weeks gestation, affects up to 5% of couples. Well-accepted causes include uterine malformation, antiphospholipid syndrome, and parental chromosomal abnormalities; however, the majority of RPL cases are idiopathic (up to 75%). This chapter covers these accepted causes of RPL and provides diagnosis and management strategies for patients falling within the above categories.

To evaluate the relationship between subclinical hypothyroidism (SCH) and the risk of miscarriage before 20 weeks of pregnancy. Literature databases were searched, including the PubMed, Web of Science, Embase and Cochrane databases, from January 1, 1980, to December 31, 2015. The following search terms were used: subclinical hypothyroidism, hypothyroidism, thyroid dysfunction, thyroid hypofunction, subclinical thyroid disease, thyroid dysfunction, pregnancy loss, abortion and miscarriage. Studies comparing the prevalence of miscarriage in pregnant women with SCH with those who were euthyroid were selected. From the studies matched, the relative risk (RR) and corresponding 95% confidence interval (95% CI) were calculated to yield outcomes. All the statistical analyses were performed using Review Manager (Revman) Version 5.3 and Stata Version 12.0 software. The publication bias of the studies was assessed by forest plot and Begg's test, while the stability of the results was evaluated by sensitivity analysis. Nine articles satisfying the inclusion criteria were analysed. Compared to euthyroid pregnant women, patients with non-treated SCH had a higher prevalence of miscarriage (RR = 1.90, 95% CI1.59-2.27, P<0.01). Additionally, SCH patients in the international diagnostic criteria group were more likely to suffer miscarriages than those in the ATA diagnostic criteria group (χ2 = 11.493, P<0.01). Moreover, there was no difference between patients with treated SCH and euthyroid women (RR = 1.14, 95% CI0.82-1.58, P = 0.43). Compared to isolated SCH women, the miscarriage risk of SCH patients with thyroid autoimmunity (TAI) was obviously higher (RR = 2.47, 95% CI1.77-3.45, P<0.01), and isolated SCH patients also had a higher prevalence of miscarriages than euthyroid women (RR = 1.45, 95% CI1.07-1.96, P = 0.02).A heterogeneity test, forest plot and Begg's test suggested that there was no significant heterogeneity or publication bias among the included articles, while the

Both ultrasound and biochemical markers either alone or in combination have been described in the literature for the prediction of miscarriage. We performed this systematic review and meta-analysis to determine the best combination of biochemical, ultrasound and demographic markers to predict miscarriage in women with viable intrauterine pregnancy. The electronic database search included Medline (1946-June 2017), Embase (1980-June 2017), CINAHL (1981-June 2017) and Cochrane library. Key MESH and Boolean terms were used for the search. Data extraction and collection was performed based on the eligibility criteria by two authors independently. Quality assessment of the individual studies was done using QUADAS 2 (Quality Assessment for Diagnostic Accuracy Studies-2: A Revised Tool) and statistical analysis performed using the Cochrane systematic review manager 5.3 and STATA vs.13.0. Due to the diversity of the combinations used for prediction in the included papers it was not possible to perform a meta-analysis on combination markers. Therefore, we proceeded to perform a meta-analysis on ultrasound markers alone to determine the best marker that can help to improve the diagnostic accuracy of predicting miscarriage in women with viable intrauterine pregnancy. The systematic review identified 18 eligible studies for the quantitative meta-analysis with a total of 5584 women. Among the ultrasound scan markers, fetal bradycardia (n=10 studies, n=1762 women) on hierarchical summary receiver operating characteristic showed sensitivity of 68.41%, specificity of 97.84%, positive likelihood ratio of 31.73 (indicating a large effect on increasing the probability of predicting miscarriage) and negative likelihood ratio of 0.32. In studies for women with threatened miscarriage (n=5 studies, n=771 women) fetal bradycardia showed further increase in sensitivity (84.18%) for miscarriage prediction. Although there is gestational age dependent variation in the fetal heart rate, a plot

Objective The goal of this study was to evaluate the etiologies and clinical outcomes of Korean recurrent pregnancy loss (RPL) patients. And also, we investigated the differences between primary and secondary RPL patients, between two and three or more pregnancy losses. Methods One hundred seventy eight women diagnosed as RPL were enrolled. We performed chromosomal analysis, thyroid stimulating hormone, prolactin, blood glucose, plasminogen activator inhibitor-1, natural killer cell proportion, anticardiolipin antibodies, antiphospholipid antibodies, lupus anticoagulant, anti-β2glycoprotein-1 antibodies, antinuclear antibody, protein C, protein S, antithrombin III, homocysteine, MTFHR gene, factor V Leiden mutation, and hysterosalphingography/hysteroscopic evaluation. Results The mean age was 34.03±4.30 years, and mean number of miscarriages was 2.69±1.11 (range, 2 to 11). Anatomical cause (13.5%), chromosomal abnormalities (5.6%), and endocrine disorders (34.3%) were observed in RPL women. Elevated natural killer cell and antiphospholipid antibodies were observed in 43.3% and 7.3% each. Among of 178 women, 77 women were pregnant. After management of those women, live birth rate was 84.4% and mean gestational weeks was 37.63±5.12. Women with three or more RPL compared with women with two RPL had more common anatomical cause such as intrauterine adhesions and lower rates of spontaneous pregnancy. Compare with secondary RPL women, immunological abnormalities were more common in primary RPL. However, miscarriage rates were not different. Conclusion Immunological factor including autoimmune and alloimmune disorders was most common etiology of RPL. Inherited thrombophilia showed different patterns with other ethnic countries. Miscarriage rates were not different between primary and secondary RPL, or between two and three or more miscarriages group. PMID:27668201

Immunological disturbances are hypothesised to play a role in recurrent miscarriage (RM) and therefore intravenous immunoglubulins (IVIg) have been tested in RM patients. The objectives were to investigate the benefits and harms of IVIg versus placebo, no intervention, or treatment as usual in women with RM. We searched the published literature in all relevant databases. Randomised trials investigating IVIg versus placebo, no intervention, or treatment as usual in women with RM. We undertook meta-analyses of aggregated data and individual patient data using a two-step approach, and we conducted bias domain assessments and trial sequential analyses to assess the risks of systematic and random errors. We identified 11 randomised clinical trials. No significant difference in the frequency of no live birth was found when IVIg was compared with placebo or treatment as usual (RR 0.92, 95% CI 0.75-1.12, p = 0.42). Trial sequential analysis showed that the required information size of 1,008 participants was not obtained. IVIg compared with placebo seems to increase the risk of adverse events. Subgroup analysis suggests that women with RM after a birth (secondary RM) seemed most likely to obtain a potential beneficial effect of IVIg (RR for no live birth 0.77, 95%CI 0.58-1.02, p = 0.06), however, trial sequential analysis showed that insufficient information is presently accrued. We cannot recommend or refute IVIg in women with RM. IVIg should therefore be assessed in further randomised clinical trials with positive outcomes before any clinical use is considered.

Idiopathic ophthalmodynia and idiopathic rhinalgia were described a few years ago. These conditions seem specific pain syndromes with a distinctive location in the eye or in the nose. We aimed to present a new prospective series in order to verify the consistency of these syndromes. We performed a descriptive study of all patients referred to our regional neurologic clinics from 2010 to 2014 because of facial pain exclusively felt in the eye or in the nose fulfilling the proposed diagnostic criteria for idiopathic ophthalmodynia and idiopathic rhinalgia. There were 9 patients with idiopathic ophthalmodynia and 7 patients with idiopathic rhinalgia, with a clear female preponderance, and a mean age at onset in the fifth decade. The pain was usually moderate and the temporal pattern was generally chronic. Only one patient reported accompaniments (hypersensitivity to the light and to the flow of air in the symptomatic eye). Preventive treatment with amitriptyline, pregabalin, or gabapentin was partially or totally effective. The clinical features of this new series parallels those of the original description, thus indicating that both idiopathic ophthalmodynia and idiopathic rhinalgia have clear-cut clinical pictures with excellent consistency both inter- and intra-individually. © 2015 American Headache Society.

BACKGROUND Despite the increasing use of intravenous immunoglobulin (IVIG) in obstetrics, information on its pharmacokinetics and optimal dosing during each trimester pregnancy is lacking. The aim of this study was to characterize IVIG pharmacokinetics in pregnant women with a history of idiopathic secondary recurrent miscarriage or obstetrical antiphospholipid syndrome and to make dosing recommendations by comparing serum immunoglobulin G (IgG) concentrations in women receiving IVIG to placebo controls, before and during pregnancy. METHODS Women enrolled in an IVIG trial for idiopathic secondary recurrent miscarriage (n = 25) or an IVIG study for obstetrical antiphospholipid syndrome (n = 10); 22 received IVIG 0.5–1.0 g/kg and 13 received the equivalent volume of saline, every 4 weeks from pre-pregnancy until 18–20 weeks of gestation, with dosing adjusted for her weight prior to each infusion. Serum IgG concentrations were measured by rate nephelometry before and 0.5 h, and 1, 2, 3 and 4 weeks following an infusion. Sampling was performed pre-pregnancy and in the first and second trimesters. RESULTS Area under the curve (AUC) did not differ significantly within the IVIG group between the three sampling periods. Estimated contributions of IVIG [calculated as mean AUC (IVIG group) minus mean AUC (control group)] were 4890.8 g h/l pre-pregnancy, 5591.4 g h/l first trimester and 4755.1 g h/l second trimester (P> 0.05, non-significant). For the IVIG 0.5 and 1.0 g/kg subgroups, the overall estimated contribution of exogenous IVIG was ∼4000 and ∼6400 g h/l, respectively. CONCLUSIONS With a weight-adjusted dosage of IVIG, drug exposure, based on AUC calculations, was maintained at the pre-pregnancy level. Therefore, we recommend a weight-adjusted dosage of IVIG during the first and second trimesters. PMID:21771770

To determine risk factors for miscarriage. A case control study was carried out at the gynaecological wards and antenatal clinics of the De Soysa Maternity Hospital in Sri Lanka. A case was defined as that of mothers with a confirmed diagnosis of partial or full expulsion of the fetus during the first 28 weeks of gestation. Controls comprised ante-natal clinic attendees whose period of gestation was <28 weeks and carrying a viable fetus. Two hundred and thirty cases and 504 controls were selected. A pre-tested interviewer-administered questionnaire and modified life events inventory were used to gather data. Multivariate logistic regression was applied separately for first and second trimester miscarriages and the results were expressed as odds ratios (OR) and as 95% confidence intervals (95% CI). Sleeping < or =8 h/day (OR:3.80, 95% CI:1.01-14.3) was found to be a risk factor for first trimester miscarriage controlling for the effect of period of gestation. Sleeping < or =8 h/day (OR:2.04, 95% CI:1.24-3.37), standing < or =3 h/day (OR:1.83, 95% CI:1.08-3.10), exposure to cooking smoke (OR:3.83, 95% CI:1.50-9.90) and physical trauma during the pregnancy (OR:43.2, 95% CI:4.55-411.4) were found to be risk factors for second trimester miscarriage controlling for the effect of period of gestation. Sleep deprivation, a sedentary lifestyle, exposure to cooking smoke and physical trauma during pregnancy were risk factors for miscarriage. Most of the risk factors are therefore modifiable.

The aim of this study was to examine the association between biological, behavioural and lifestyle risk factors and risk of miscarriage. Population-based case-control study. Case-control study nested within a population-based, two-stage postal survey of reproductive histories of women randomly sampled from the UK electoral register. Six hundred and three women aged 18-55 years whose most recent pregnancy had ended in first trimester miscarriage (<13 weeks of gestation; cases) and 6116 women aged 18-55 years whose most recent pregnancy had progressed beyond 12 weeks (controls). Women were questioned about socio-demographic, behavioural and other factors in their most recent pregnancy. First trimester miscarriage. After adjustment for confounding, the following were independently associated with increased risk: high maternal age; previous miscarriage, termination and infertility; assisted conception; low pre-pregnancy body mass index; regular or high alcohol consumption; feeling stressed (including trend with number of stressful or traumatic events); high paternal age and changing partner. Previous live birth, nausea, vitamin supplementation and eating fresh fruits and vegetables daily were associated with reduced risk, as were feeling well enough to fly or to have sex. After adjustment for nausea, we did not confirm an association with caffeine consumption, smoking or moderate or occasional alcohol consumption; nor did we find an association with educational level, socio-economic circumstances or working during pregnancy. The results confirm that advice to encourage a healthy diet, reduce stress and promote emotional wellbeing might help women in early pregnancy (or planning a pregnancy) reduce their risk of miscarriage. Findings of increased risk associated with previous termination, stress, change of partner and low pre-pregnancy weight are noteworthy, and we recommend further work to confirm these findings in other study populations.

To date, the role of male factor contributing in evaluation of spontaneous recurrent pregnancy loss (RPL) has been less investigated and there is discrepancy in the role of Y chromosome microdeltions in RPL. Therefore, the current study was designed to examine whether Y chromosome microdeletions were associated with RPL in an Iranian population. One hundred men from couples, experiencing three or more RPLs, and one hundred normal men from couples with at least one child and no history of miscarriages as control group were included. Genomic DNA was extracted from peripheral blood and tested for Y chromosome microdeletions in AZFa, AZFb and AZFc regions using two multiplex PCR. None of the men in the case and control groups had any microdeletions in the AZFa, AZFb and AZFc regions. It seems that Y chromosome microdeletion is not associated with recurrent pregnancy loss, therefore performing this test in Iranian couples with RPL is not recommended.

Aim To investigate association of factor V Leiden, prothrombin G20210A, MTHFR C677T and PAI-1 4G/5G polymorphisms with recurrent pregnancy loss in Bosnian women. Methods A total of 60 women with two or more consecutive miscarriages before 20 weeks of gestation with the same partners and without history of known causes or recurrent pregnancy loss were included. A control group included 80 healthy women who had one or more successful pregnancies without history of any complication which could be associated with miscarriages. Genotyping of factor V Leiden, prothrombin G20210A, MTHFR C677T and PAI-1 4G/5G polymorphisms were performed by polymerase chain reaction/restriction fragments length polymorphism method (PCR/RFLP). Results Both factor V Leiden and MTHFR C677T polymorphisms were significantly associated with recurrent pregnancy loss (RPL) in Bosnian women while prothrombin G20210A and PAI-1 4G/5G polymorphisms did not show strongly significant association. Conclusion The presence of thrombophilic polymorphisms may predispose women to recurrent pregnancy loss. Future investigation should be addressed in order to find when carriers of those mutations, polymorphisms should be treated with anticoagulant therapy.

In this study, the transcriptome profile of cows who experienced miscarriage during peri-implantation was investigated. The transcriptome was checked by RNA sequencing, and the analyzed by bioinformatics methods. The results suggested that serum progesterone levels were significantly decreased in the cows who miscarried compared with the pregnant cows at 18 d, 21d, 33 d, 39 d and 51 d after artificial insemination. The RNA sequencing results suggested that 32, 176, 5, 10 and 2 differentially expressed genes (DEGs) were identified in the pregnant cows and the cows who miscarried at 18, 21, 33, 39 and 51 d after artificial insemination. Furthermore, the DEGs were analysed with hierarchical clustering and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and 15, 101, 1, 2 and 2 DEGs were upregulated, and 17, 74, 4, 8 and 0 DEGs were downregulated in the cows in the pregnant and miscarriage groups, respectively at 18, 21 33, 39 and 51 d after artificial insemination. These DEGs were distributed to 13, 20, 3, 6 and 20 pathways. This analysis has identified genes and pathways crucial for pregnancy and miscarriage in cows.

2017-10-01

The objectives of this cross-sectional study were to determine whether depressive and perinatal grief symptoms vary according to time since miscarriage and to test whether childlessness and satisfaction with healthcare services influence symptom duration. A total of 245 women who had experienced a miscarriage answered a self-report questionnaire, indicating the date of their miscarriage and assessing their present level of depressive and perinatal grief symptoms. They also provided sociodemographic characteristics and indicated their level of satisfaction with healthcare services. One-way analyses of variance indicated that women who had miscarried within the past 6 months reported higher scores for depressive symptoms than did women who had miscarried between 7 and 12 months ago and more than 2 years ago. However, when controlling for childlessness and satisfaction with healthcare services, those differences became respectively marginal and non-significant, indicating that depressive symptoms are similar across time for more than 2 years after the loss. Regarding perinatal grief, results revealed that symptoms significantly decreased across time only for women with children and women who were satisfied with healthcare services. For childless women and those dissatisfied with healthcare services, perinatal grief symptoms did not vary according to time since miscarriage. Results suggest that, particularly for women who are childless and/or dissatisfied with healthcare services, depressive and perinatal grief symptoms persist long after a miscarriage. These results highlight the importance of paying particular attention to more vulnerable women and of improving healthcare services post-miscarriage.

Overweight and obesity are less closely associated with idiopathic intracranial hypertension (IIH) in young children than in post-pubescent children and adults. We examined the hypothesis that being overweight or obese (body mass index (BMI) ⩾ 85th percentile) in children is a risk factor for IIH recurrence. A total of 43 children with IIH who were followed up for an average of 9 ± 3.4 years were evaluated in a retrospective case-control series. The rate of IIH recurrence was compared between children of healthy weight and children presenting with overweight or obesity, using survival curve analysis. The overall risk for long-term IIH recurrence in children is ~20%. Following weight stratification, the risk for IIH recurrence in our cohort was fivefold higher in children with a BMI ⩾ 85th percentile (57%) than in healthy weight children (11%; log-rank test P = 0.04). Pediatricians may consider counseling families that weight control may be a means of decreasing the risk of IIH recurrence.

Inherited Thrombophilia and Pregnancy Complications: Should We Test?

Arachchillage, Deepa R J; Makris, Mike

2018-06-04

Recurrent miscarriages and pregnancy-related complications cause significant stress to couples looking for successful pregnancy outcome as well as to health care professionals. There is conflicting evidence with respect to the presence and the strength of associations between inherited thrombophilia and these complications. A complete thrombophilia screen is expensive, and no proven effective treatment for women with recurrent miscarriage and inherited thrombophilia is currently available. Based on the concept of microvascular thrombosis of the placenta, women with recurrent miscarriage and placenta-related complications frequently get treated with antithrombotic therapy. In this narrative review, the authors explore the evolving understanding and evidence of inherited thrombophilia in recurrent miscarriages and other pregnancy complications, and whether antithrombotic treatment would modify pregnancy outcome in women with inherited thrombophilia. Finally, they provide some personal recommendations based on available evidence for clinical practice. In summary, inherited thrombophilia testing is not required outside a clinical trial for women with recurrent pregnancy losses or late pregnancy complications. The presence of thrombophilia markers does not generally indicate additional therapy during pregnancy, even if a heritable thrombophilic defect is found in women with recurrent miscarriages or late pregnancy complications.

Studies on vitrectomy with and without internal limiting membrane (ILM) peeling for idiopathic epiretinal membrane (ERM) have yielded uncertain results regarding clinical outcomes and recurrence rates. To compare the clinical outcomes of vitrectomy with and without ILM peeling for idiopathic ERM. Databases, including PubMed, Embase, Cochrane, Web of Science, Google Scholar, CNKI databases, FDA.gov, and ClinicalTrials.gov, published until July 2016, were searched to identify studies comparing the clinical outcomes following vitrectomy with ERM and ILM peeling and with only ERM peeling, for treating idiopathic ERM. Studies with sufficient data were selected. Pooled results were expressed as mean differences (MDs) and risk ratios (RRs) with corresponding 95% confidence intervals (CI) for vitrectomy with and without ILM peeling with regard to postoperative best corrected visual acuity (BCVA), central retinal thickness (CRT), and ERM recurrence rate. Eleven retrospective studies and one randomized controlled trial involving 756 eyes were identified. This demonstrated that the postoperative BCVA within 12 months was significantly better in the non-ILM peeling group (MD = 0.04, 95% CI: 0.00 to 0.08; P = 0.0460), but that the patients in the ILM peeling group had significantly better postoperative BCVA after 18 months (MD = -0.13, 95% CI: -0.23 to -0.04; P = 0.0049) than did those in the non-ILM peeling group. The non-ILM peeling group exhibited a higher reduction in postoperative CRT (MD = 51.55, 95% CI:-84.23 to -18.88; P = 0.0020) and a higher recurrence rate of ERM (RR = 0.34, 95% CI:0.16 to 0.72; P = 0.0048) than did the ILM peeling group. However, the improvement rates of BCVA (RR = 1.03, 95% CI:0.72 to 1.47; P = 0.8802) and postoperative CRTs (MD = 18.15, 95% CI:-2.29 to 38.60; P = 0.0818) were similar between the two groups.

Background Immunological disturbances are hypothesised to play a role in recurrent miscarriage (RM) and therefore intravenous immunoglubulins (IVIg) have been tested in RM patients. Objectives The objectives were to investigate the benefits and harms of IVIg versus placebo, no intervention, or treatment as usual in women with RM. Search Strategy We searched the published literature in all relevant databases. Selection Criteria Randomised trials investigating IVIg versus placebo, no intervention, or treatment as usual in women with RM. Data Collection and Analysis We undertook meta-analyses of aggregated data and individual patient data using a two-step approach, and we conducted bias domain assessments and trial sequential analyses to assess the risks of systematic and random errors. Main Results We identified 11 randomised clinical trials. No significant difference in the frequency of no live birth was found when IVIg was compared with placebo or treatment as usual (RR 0.92, 95% CI 0.75–1.12, p = 0.42). Trial sequential analysis showed that the required information size of 1,008 participants was not obtained. IVIg compared with placebo seems to increase the risk of adverse events. Subgroup analysis suggests that women with RM after a birth (secondary RM) seemed most likely to obtain a potential beneficial effect of IVIg (RR for no live birth 0.77, 95%CI 0.58–1.02, p = 0.06), however, trial sequential analysis showed that insufficient information is presently accrued. Conclusion We cannot recommend or refute IVIg in women with RM. IVIg should therefore be assessed in further randomised clinical trials with positive outcomes before any clinical use is considered.

Alpha Lipoic Acid (ALA) is a safe natural molecule that exerts a selective immunomodulating activity with antioxidant and anti-inflammatory properties. This randomized controlled clinical trial (RCT) tested the effect of the vaginal administration with ALA or Progesterone, in subchorionic hematoma resorption in women with threatened miscarriage. 400 mg of vaginal Progesterone or 10 mg of vaginal ALA were administered to sixty-two pregnant women, in the first trimester of gestation with threatened miscarriage and subchorionic hematoma. Controls were patients who chose not to receive any treatment. In the ALA group the subchorionic hematoma was reabsorbed more quickly in comparison with the progression detected in Progesterone group (p ≤ 0.05). The other parameters checked (pelvic pain and vaginal bleeding) did not show any significant difference and a smaller number of miscarriages was recorded in the ALA group, compared to Progesterone group. Our data provides the first evidence of the efficacy of ALA, administered by vaginal route, in the healing process of patients with threatened miscarriage, thus supporting the normal course of pregnancy.

Recurrent pericarditis is a troublesome complication of idiopathic acute pericarditis and occurs more frequently in pediatric patients after cardiac surgery (postpericardiotomy syndrome). Conventional treatment with nonsteroidal antiinflammatory drugs, corticosteroids, and colchicine is not always effective or may cause serious adverse effects. There is no consensus, however, on how to proceed in those patients whose disease is refractory to conventional therapy. In such cases, human intravenous immunoglobulin, immunosuppressive drugs, and biological agents have been used. In this report we describe 2 patients with refractory recurrent pericarditis after cardiac surgery who were successfully treated with 3 and 5 monthly high-dose (2 g/kg) intravenous immunoglobulin until resolution of the effusion. Our experience supports the effectiveness and safety of this therapy. Copyright © 2014 by the American Academy of Pediatrics.

Despite the putative intrauterine origins of childhood (0-14 years) leukaemia, it is complex to assess the impact of perinatal factors on disease onset. Results on the association of maternal history of fetal loss (miscarriage/stillbirth) with specific disease subtypes in the subsequent offspring are in conflict. We sought to investigate whether miscarriage and stillbirth may have different impacts on the risk of acute lymphoblastic leukaemia (ALL) and of its main immunophenotypes (B-cell and T-cell ALL), as contrasted to acute myeloid leukaemia (AML). One thousand ninety-nine ALL incidents (957 B-ALL) and 131 AML cases along with 1:1 age and gender-matched controls derived from the Nationwide Registry for Childhood Hematological Malignancies and Brain Tumors (1996-2013) were studied. Multivariable regression models were used to assess the roles of previous miscarriage(s) and stillbirth(s) on ALL (overall, B-, T-ALL) and AML, controlling for potential confounders. Statistically significant exposure and disease subtype-specific associations of previous miscarriage(s) exclusively with AML [odds ratio (OR) 1.67, 95% confidence interval (CI) 1.00, 2.81] and stillbirth(s) with ALL [OR 4.82, 95% CI 1.63, 14.24] and B-ALL particularly, emerged. Differential pathophysiological pathways pertaining to genetic polymorphisms or cytogenetic aberrations are likely to create hostile environments leading either to fetal loss or the development of specific leukaemia subtypes in subsequent offspring, notably distinct associations of maternal miscarriage history confined to AML and stillbirth history confined to ALL (specifically B-ALL). If confirmed and further supported by studies revealing underlying mechanisms, these results may shed light on the divergent leukemogenesis processes. © 2015 John Wiley & Sons Ltd.

We report population-based data on still birth, induced abortion and miscarriage from the Indian state of Bihar to assess the magnitude of the problem and to inform corrective action. A representative sample of women from all districts of Bihar with a pregnancy outcome in the last 12 months was obtained through multistage sampling in early 2012. Still birth rate was calculated as fetuses born with no sign of life at 7 or more months of gestation per 1,000 births. Induced abortion and miscarriage rates were defined as expulsion of dead fetuses at less than 7 months of gestation induced by any means or without inducement, respectively, per 1000 pregnancies that had an outcome. Multiple regression models were used to explore possible associations with stillbirths, induced abortions and miscarriages. Multi-level models were developed for the relatively less developed north zone and for the south zone of Bihar to examine contextual factors associated with still births, induced abortions and miscarriages. Still birth rate was estimated as 20 per 1,000 births (95% CI 15.6-24.5), and induced abortion and miscarriage rates as 8.6 (6.6-10.6), and 46 (40.8-51.3) per 1,000 pregnancies with outcome, respectively. The odds of induced abortion and miscarriage were significantly higher in the south zone (odds ratio 2.53 [95% CI 1.79-3.57] and 1.27 [95% CI 1.10-1.47], respectively). In the multi-level model for the north zone, the odds of induced abortion were higher for women with husband's having mean years of education higher than the state mean (2.62; 95% CI 1.47-4.69). Among the nine divisions of Bihar, comprising of groups of districts, higher induced abortion rate was associated with lower neonatal mortality rate (R(2) = 0.68, p = 0.01). These population-based data show a significant burden of still births in Bihar, suggesting that addressing these must become an important part of maternal and child health initiatives.

To study the impact of administration of dydrogesterone in early pregnancy on pregnancy outcome and its correlation with Th1 and Th2 cytokine levels. Double-blind, randomized, placebo-controlled study. A medical college and its associated hospital. Women with either: [1] a history of idiopathic recurrent pregnancy loss (RPL), in either a dydrogesterone group or a placebo group, or [2] no history of miscarriage. Dydrogesterone 20 mg/day from confirmation of pregnancy to 20 weeks of gestation. Occurrence of another pregnancy loss and concentrations of T-helper (Th)1 (interferon-γ and tumor necrosis factor-α) and Th2 (interleukin (IL)-4 and IL-10) cytokines in serum at recruitment (4-8 weeks of gestation) and at abortion or 20 weeks of gestation, using commercially available ELISA kits. Occurrence of another abortion after 3 consecutive abortions was significantly higher (29 of 173; 16.76%) in women with RPL compared with healthy pregnant controls (6 of 174; 3.45%). Risk of occurrence of miscarriage after 3 abortions was 2.4 times higher in the placebo group vs. the treatment group (risk ratio=2.4, 95% CI=1.3-5.9). Mean gestational age at delivery (excluding those aborted before 20 weeks of gestation) increased significantly in the dydrogesterone group (38.01±1.96 weeks) compared with the placebo group (37.23±2.41 weeks). Baby weight was significantly lower in the placebo group (2421.4±321.6 g) compared with the healthy pregnant controls (2545.3±554.3 g). At recruitment, serum IL-4 and tumor necrosis factor-α levels were significantly lower in the RPL group compared with the healthy pregnant controls. However, serum interferon-γ level was significantly higher in the RPL group (8.87±0.72 pg/mL) compared with the healthy pregnant controls (8.08±1.27 pg/mL). The present study supports the use of dydrogesterone in women with recurrent abortions to improve pregnancy outcome, such as a reduction in abortions and improved gestational age and baby weight at delivery

Idiopathic hypercalciuria and formation of calcium renal stones

PubMed Central

Coe, Fredric L.; Worcester, Elaine M.; Evan, Andrew P.

2018-01-01

The most common presentation of nephrolithiasis is idiopathic calcium stones in patients without systemic disease. Most stones are primarily composed of calcium oxalate and form on a base of interstitial apatite deposits, known as Randall’s plaque. By contrast some stones are composed largely of calcium phosphate, as either hydroxyapatite or brushite (calcium monohydrogen phosphate), and are usually accompanied by deposits of calcium phosphate in the Bellini ducts. These deposits result in local tissue damage and might serve as a site of mineral overgrowth. Stone formation is driven by supersaturation of urine with calcium oxalate and brushite. The level of supersaturation is related to fluid intake as well as to the levels of urinary citrate and calcium. Risk of stone formation is increased when urine citrate excretion is <400 mg per day, and treatment with potassium citrate has been used to prevent stones. Urine calcium levels >200 mg per day also increase stone risk and often result in negative calcium balance. Reduced renal calcium reabsorption has a role in idiopathic hypercalciuria. Low sodium diets and thiazide-type diuretics lower urine calcium levels and potentially reduce the risk of stone recurrence and bone diseas PMID:27452364

One factor women consider when deciding whether to pursue amniocentesis is the risk of miscarriage. People use mechanisms like anchoring, or the prior belief regarding the magnitude of risk, as a frame of reference for new information. This study aimed to determine a woman's perception of miscarriage risk associated with amniocentesis before and after genetic counseling and to determine what factors anchor a woman's perception of miscarriage risk. One hundred thirteen women being seen for prenatal genetic counseling and possible amniocentesis at six Houston clinics participated in the two-part anonymous survey. While most women (56.7 %) perceived the risk as low or average pre-counseling and indicated the numeric risk of amniocentesis as <1 %, significantly more patients (73 %) correctly identified the numeric risk as <1 % post-counseling (p < 0.0001). However, the majority of patients' qualitative risk perception did not change after the genetic counseling session (60 %). Those who changed their feeling about the risk after counseling showed a decreased perception of the risk (p < 0.0001). Participants who elected amniocentesis had a significantly lower perception of the risk (p = 0.017) whereas those who declined amniocentesis were more likely to view the risk as high (p = 0.004). The only two anchoring factors that had an effect were having a friend or relative with a personal or family history of a genetic disorder (p = 0.001) and having a child already (p = 0.038); both were associated with a lower risk perception. The lack of significant factors may reflect the uniqueness of each patient's risk assessment framework and reinforces the importance of genetic counseling to elucidate individual concerns, particularly as non-invasive prenatal testing becomes more widely available and further complicates the prenatal testing landscape.

Idiopathic sclerosing encapsulating peritonitis (or abdominal cocoon) is a rare cause of small bowel obstruction, especially in adult population. Diagnosis is usually incidental at laparotomy. We discuss one such rare case, outlining the fact that an intra-operative surprise diagnosis could have been facilitated by previous investigations. A 56 year-old man presented in A&E department with small bowel ileus. He had a history of 6 similar episodes of small bowel obstruction in the past 4 years, which resolved with conservative treatment. Pre-operative work-up did not reveal any specific etiology. At laparotomy, a fibrous capsule was revealed, in which small bowel loops were encased, with the presence of interloop adhesions. A diagnosis of abdominal cocoon was established and extensive adhesiolysis was performed. The patient had an uneventful recovery and follow-up. Idiopathic sclerosing encapsulating peritonitis, although rare, may be the cause of a common surgical emergency such as small bowel ileus, especially in cases with attacks of non-strangulating obstruction in the same individual. A high index of clinical suspicion may be generated by the recurrent character of small bowel ileus combined with relevant imaging findings and lack of other plausible etiologies. Clinicians must rigorously pursue a preoperative diagnosis, as it may prevent a "surprise" upon laparotomy and result in proper management.

Increased risk of miscarriage among women experiencing physical or sexual intimate partner violence during pregnancy in Guatemala City, Guatemala: cross-sectional study

PubMed Central

2011-01-01

Background Violence against women by their male intimate partners (IPV) during pregnancy may lead to negative pregnancy outcomes. We examined the role of IPV as a potential risk factor for miscarriage in Guatemala. Our objectives were: (1) To describe the magnitude and pattern of verbal, physical and sexual violence by male intimate partners in the last 12 months (IPV) in a sample of pregnant Guatemalans; (2) To evaluate the influence of physical or sexual IPV on miscarriage as a pregnancy outcome. Methods All pregnant women reporting to the maternity of a major tertiary care public hospital in Guatemala City from June 1st to September 30th, 2006 were invited to participate in this cross-sectional study. The admitting physician assessed occurrence of miscarriage, defined as involuntary pregnancy loss up to and including 28 weeks gestation. Data on IPV, social and demographic characteristics, risk behaviours, and medical history were collected by interviewer-administered questionnaire. Laboratory testing was performed for HIV and syphilis. The relationship between IPV and miscarriage was assessed through multivariable logistic regression. Results IPV affected 18% of the 1897 pregnant Guatemalan women aged 15-47 in this sample. Verbal IPV was most common (16%), followed by physical (10%) and sexual (3%) victimisation. Different forms of IPV were often co-prevalent. Miscarriage was experienced by 10% of the sample (n = 190). After adjustment for potentially confounding factors, physical or sexual victimisation by a male intimate partner in the last 12 months was significantly associated with miscarriage (ORadj 1.1 to 2.8). Results were robust under a range of analytic assumptions. Conclusions Physical and sexual IPV is associated with miscarriage in this Guatemalan facility-based sample. Results cohere well with findings from population-based surveys. IPV should be recognised as a potential cause of miscarriage. Reproductive health services should be used to screen

To estimate (1) lifetime prevalence of physical and sexual victimisation from husbands among a national sample of Bangladeshi women, (2) associations of unwanted pregnancy and experiences of husband violence, and (3) associations of miscarriage, induced abortion, and fetal death/stillbirth and such victimisation. Cross-sectional, nationally representative study utilizing matched husband-wife data from the 2004 MEASURE Bangladesh Demographic Health Survey. Bangladesh. Married Bangladeshi women ages 13-40 years old (n = 2677). Bivariate and multivariate logistic regression analysis. Relations of intimate partner violence to unwanted pregnancy, miscarriage, induced abortion and stillbirth. Three out of four (75.6%) Bangladeshi women experienced violence from husbands. Less educated, poorer, and Muslim women were at greatest risk. Women experiencing violence from husbands were more likely to report both unwanted pregnancy (ORs(adj) 1.46-1.54) and a pregnancy loss in the form of miscarriage, induced abortion, or stillbirth (ORs(adj) 1.43-1.69). Assessed individually, miscarriage was more likely among victimised women (OR(adj) 1.81). A nonsignificant trend was detected for increased risk of induced abortion (OR(adj) 1.64); stillbirth was unrelated to violence from husbands. Intimate partner violence is extremely prevalent and relates to unwanted pregnancy and higher rates of pregnancy loss or termination, particularly miscarriages, among Bangladeshi women. Investigation of mechanisms responsible for these associations will be critical to developing interventions to improve maternal, fetal, and neonatal health. Such programmes may be vital to reducing the significant health and social costs associated with both husband violence and unwanted and adverse pregnancy outcomes.

Objectives: Idiopathic granulomatous mastitis (IGM) is a rare benign disorder of the breast whose aetiology is controversial, and is often misdiagnosed clinically and radiologically as mammary malignancy; as a result, it may be incorrectly treated. Although no standard treatment is available for this chronic disease, surgery with or without corticosteroids has been tried with controversial results. This study discusses the clinical presentation, diagnosis, management, recurrence, and follow-up data of IGM with a review of relevant literature. Methods: From 2009–2012, the Breast Unit at Sultan Qaboos University Hospital, Oman, conducted a clinical study on 20 patients with breast lumps. Their clinical and radiological examinations were indeterminate, and a diagnosis of granulomatous mastitis was established only by histopathology. Results: The majority of the patients were cases of unknown aetiology, who presented with a unilateral breast mass. A few patients had a mass with an abscess, along with axillary lymphadenopathy. A total of 4 patients were suspected of malignancy using radiology. In all patients, sterilised pus was sent for culture and sensitivity. Microscopy showed the characteristic pattern of granulomatous inflammation. All patients were treated with antibiotics for 6 weeks, and the mean follow-up period was 15 months (11–33 months). All patients had complete remission with no further recurrence. Conclusion: This single largest study of cases of IGM in Oman highlights the pitfalls in diagnosing this non-neoplastic disease of unknown aetiology and uncertain pathogenesis. It emphasises IGM’s excellent response to antibiotics, which is crucial, as IGM is a disease which is notoriously difficult and controversial to treat. PMID:23862029

Serum levels of folate and cobalamin in women with recurrent spontaneous abortion.

PubMed

Sütterlin, M; Bussen, S; Ruppert, D; Steck, T

1997-10-01

We evaluated the folate and cobalamin status in 29 non-pregnant women with a history of recurrent spontaneous abortion (three or more consecutive) of unknown aetiology in comparison to 29 healthy nulligravidae of similar reproductive age (controls). Serum concentrations of folate and cobalamin showed no significant differences between the two groups. No correlation between age and vitamin concentrations was found. In the study group there was a significant negative correlation of the number of previous abortions and the concentration of serum folate. Patients with at least four previous miscarriages had significantly lower serum values of folic acid than women with three abortions, but not than controls. The underlying cause of this finding remains unclear. In conclusion, the serum concentrations of folic acid and vitamin B12 are not significantly altered in women with unexplained recurrent spontaneous abortions, and an association between a deficiency of these vitamins and an increased risk of pregnancy loss appears to be questionable in the majority of gestations.

Preston et al. indicated that Protein S (PS) deficiency was associated with stillbirths but not miscarriages. The PS-Tokushima missense variant was reported to serve as a genetic risk factor for deep vein thrombosis in the Japanese population. A previous cross-sectional study showed no increase in the prevalence of PS-Tokushima in patients with recurrent early pregnancy loss or in patients with intra uterine fetal death and/or fetal growth restriction. There has been limited number of prospective studies examining the pregnancy outcome in patients with both a PS deficiency and recurrent pregnancy loss (RPL). We examined the association between PS deficiency, PS-Tokushima and RPL. The study group consisted of 355 Japanese women with two or more consecutive pregnancy losses and 101 parous women. The frequency of PS-Tokushima and the subsequent live birth rate in relation to a PS deficiency defined as low PS-specific activity (total PS activity/total PS antigen) and the carriage of PS-Tokushima were examined. There was no significant difference in the frequency of PS-Tokushima between patients and controls. The 8 patients carriers of PS-Tokushima variant were capable of a subsequent live birth without the use of heparin. There was no significant difference in subsequent live birth rates between patients with low or normal PS-specific activity/PS activity without heparin prophylaxis after excluding miscarriages caused by an abnormal embryonic karyotype using multivariate logistic regression analysis. There was no association between PS-Tokushima and RPL and a PS deficiency or low PS activity was shown not to serve as a reliable clinical predictor of subsequent miscarriage.

Juvenile idiopathic arthritis is the most common rheumatic disease in childhood, occurring in approximately 1:500 children. Despite a recent expansion in treatment options and improvement of outcomes, significant morbidity still occurs. This article outlines the clinical manifestations, assessment, detection of complications, treatment options and monitoring requirements, with the aid of guidelines recently published by The Royal Australian College of General Practitioners, which provide practical support for general practitioners to ensure best practice care and to prevent lifelong disability in patients with juvenile idiopathic arthritis. General practice plays an important role in the early detection, initial management and ongoing monitoring of children with juvenile idiopathic arthritis. Early detection involves understanding the classification framework for subtypes of juvenile idiopathic arthritis, and being aware of the clinical manifestations and how to look for them, through history, examination and appropriate investigation. The major extra-articular manifestations of juvenile idiopathic arthritis are uveitis and growth disturbance. Treatment options include nonsteroidal anti-inflammatory drugs, methotrexate, biologic agents, and corticosteroids. Management using a multidisciplinary approach can prevent long term sequelae. Unfortunately, approximately 50% of children will have active disease as adults.

Misoprostol is used for the medical management of miscarriage as it is more effective in the early stages of pregnancy. Letrozole has an anti-estrogen effect and is used for the pretreatment of miscarriage with misoprostol. The aim of this study was compare the efficacy and safety of letrozole with placebo pretreatment in the medical management of first trimester missed miscarriage. This was a prospective randomized case-control study. Four hundred and thirty-eight women were randomly divided into two groups of 219; the placebo group received placebo tablets twice daily for 3 days, followed by 800 micrograms of misoprostol vaginally on the fourth day of enrolment, while the letrozole group received letrozole 10 mg twice daily for three days followed by 800 micrograms misoprostol administered vaginally. Symptoms and side effects were recorded, and the women advised to return to hospital if they experienced severe pain or bleeding or intolerable side effects and to report to hospital for a check-up one week after misoprostol administration. Ultrasound was done seven days after misoprostol administration to monitor outcomes. Surgical evacuation was carried out if medical management failed. There were significant differences between the two groups, with better outcomes found for the letrozole group in terms of rates of complete miscarriage, onset of vaginal bleeding, and interval between induction and onset of expulsion (p < 0.001). A higher rate of nausea and vomiting was reported for the letrozole group (p = 0.002). Differences between groups with regard to pre- and post-termination hemoglobin levels, fever, severe pain and severe bleeding needing evacuation were not statistically significant. Adding letrozole to misoprostol improves the success rate and decreases the interval between induction and expulsion in cases of first trimester miscarriage; however, nausea and vomiting is higher with letrozole.

The current standard of care for management of patients with recurrent pregnancy loss is expectant management. However, the emotional impact of pregnancy losses and the urgency to conceive often leads couples to consider a variety of fertility treatments. The objective of this study is to report the time to next pregnancy and subsequent live birth and miscarriage rates in fertile patients with recurrent pregnancy loss (RPL) who choose to attempt spontaneous conception compared to those that opt to pursue fertility treatment. Retrospective cohort study of one hundred and fifty-eight fertile RPL patients treated at a university-based fertility center. Patients were followed for a minimum of 6 months. Patients were encouraged to attempt spontaneous conception, but allowed to initiate fertility treatments (ovarian stimulation, insemination, IVF or PGS) according to their preferences. Main outcome measures were time to next pregnancy and pregnancy outcome. For those patients who achieved a spontaneous conception, 88% conceived within 6 months, with a median time of 2 months and range of 1-10 months. Patients using IUI, IVF and PGS conceived in a median of 3, 4 and 5 months, respectively. The live birth rate and clinical miscarriage rate was not improved with any fertility treatment. In the fertile RPL patient population, there does not appear to be a benefit to proceeding directly with fertility treatment. Patients should be encouraged to attempt spontaneous conception for at least 6 months.

This study aims to evaluate the demographic and clinical characteristics of patients with idiopathic and non-idiopathic vocal cord paralysis (VCP). This retrospective cohort was performed on data extracted from medical files of 92 consecutive patients (43 males, 49 females; median age 52.1±23.1 years; min. 1 - max. 87) with VCP diagnosed in the otorhinolaryngology department between April 2012 and December 2015. Diagnoses associated with VCP, side of involvement (right, left or bilateral) and previous medical histories were noted and compared between patients with idiopathic and non-idiopathic VCP. Vocal cord paralysis occurred on the left side (n=56, 60.9%), right side (n=28, 30.4%) or bilaterally (n=8, 8.7%). A clinical entity related with VCP was identified in 63 patients (68.5%), while 29 (31.5%) patients had idiopathic VCP. Most common etiologies for VCP were thyroid surgery (n=32, 34.8%), cardiovascular surgery (n=9, 9.8%), lung cancer (n=6, 6.5%) and cardiac anomalies (n=4, 4.3%), respectively. Patients with idiopathic VCP were significantly older (p<0.001), while gender distribution (p=0.121) and side of involvement (p=0.340) did not differ between two groups. Vocal cord paralysis is a relatively common clinical entity with substantial rate of morbidity. Identification of the underlying etiology and awareness on the clinical characteristics are keystones for foreseeing complications and determining the appropriate therapeutic modality.

Idiopathic hypersomnia.

Idiopathic hypersomnia continues to evolve from the concept of "sleep drunkenness" introduced by Bedrich Roth in Prague in 1956 and the description of idiopathic hypersomnia with two forms, polysymptomatic and monosymptomatic, by the same Bedrich Roth in 1976. The diagnostic criteria of idiopathic hypersomnia have varied with the successive revisions of the International classifications of sleep disorders, including the recent 3rd edition. No epidemiological studies have been conducted so far. Disease onset occurs most often during adolescence or young adulthood. A familial background is often present but rigorous studies are still lacking. The key manifestation is hypersomnolence. It is often accompanied by sleep of long duration and debilitating sleep inertia. Polysomnography (PSG) followed by a multiple sleep latency test (MSLT) is mandatory, as well as a 24 h PSG or a 2-wk actigraphy in association with a sleep log to ensure a total 24-h sleep time longer than or equal to 66O minutes, when the mean sleep latency on the MSLT is longer than 8 min. Yet, MSLT is neither sensitive nor specific and the polysomnographic diagnostic criteria require continuous readjustment and biologic markers are still lacking. Idiopathic hypersomnia is most often a chronic condition though spontaneous remission may occur. The condition is disabling, sometimes even more so than narcolepsy type 1 or 2. Based on neurochemical, genetic and immunological analyses as well as on exploration of the homeostatic and circadian processes of sleep, various pathophysiological hypotheses have been proposed. Differential diagnosis involves a number of diseases and it is not yet clear whether idiopathic hypersomnia and narcolepsy type 2 are not the same condition. Until now, the treatment of idiopathic hypersomnia has mirrored that of the sleepiness of narcolepsy type 1 or 2. The first randomized, double-blind, placebo-controlled trials of modafinil have just been published, as well as a double

Plasminogen activator inhibitor type 1 (PAI-1) regulates fibrinolysis, and the common promoter region variants -675G/A (4G/5G) and -844G/A are associated with increased thrombotic risk. Despite evidence linking altered fibrinolysis with adverse pregnancy events, including idiopathic recurrent pregnancy loss (RPL), the contribution of PAI-1 variants to RPL risk remains controversial. We investigated the association between the PAI-1 -844G/A and 4G/5G (-675G/A) variants with altered risk of RPL. This was a case-control study involving 304 women with confirmed RPL and 371 age- and ethnically matched control women. PAI-1 genotyping was performed by PCR single-specific primer -675 (G/A) and real-time PCR (-844G/A) analysis. Minor allele frequency (MAF) of 4G/5G (P < 0.001), but not -844G/A (P = 0.507), was higher in RPL cases. PAI-1 4G/5G single-nucleotide polymorphism (SNP) was significantly associated with RPL under additive, dominant, and recessive genetic models; no association of -844G/A with RPL was seen irrespective of the genetic model tested. Taking common -844G/5G haplotype as reference (OR = 1.00), multivariate analysis confirmed the association of 4G-containing -844A/4G (P < 0.001) and -844G/4G (P = 0.011) haplotypes with increased RPL risk. 4G/5G, but not -844G/A, PAI-1 variant is associated with an increased risk of RPL. © 2013 John Wiley & Sons Ltd.

Orthosis noncompliance after the Ponseti method for the treatment of idiopathic clubfeet: a relevant problem that needs reevaluation.

Idiopathic talipes equinovarus is the most common congenital defect characterized by the presence of a congenital dysplasia of all musculoskeletal tissues distal to the knee. For many years, the treatment has been based on extensive surgery after manipulation and cast trial. Owing to poor surgical results, Ponseti developed a new treatment protocol consisting of manipulation with cast and an Achilles tenotomy. The new technique requires 4 years of orthotic management to guarantee good results. The most recent studies have emphasized how difficult it is to comply with the orthotic posttreatment protocol. Poor compliance has been attributed to parent's low educational and low income level. The purpose of the study is to evaluate if poor compliance is due to the complexity of the orthotic use or if it is related to family education, cultural, or income factors. Fifty-three patients with 73 idiopathic talipes equinovarus feet were treated with the Ponseti technique and followed for 48 months after completing the cast treatment. There was a male predominance (72%). The mean age at presentation was 1 month (range: 1 wk to 7 mo). Twenty patients (38%) had bilateral involvement, 17 patients (32%) had right side affected, and 16 patients (30%) had the left side involved. The mean time of manipulation and casting treatment was 6 weeks (range: 4 to 10 wk). Thirty-eight patients (72%) required Achilles tenotomy as stipulated by the protocol. Recurrence was considered if there was a deterioration of the Dimeglio severity score requiring remanipulation and casting. Twenty-four out of 73 feet treated by our service showed the evidence of recurrence (33%). Sex, age at presentation, cast treatment duration, unilateral or bilateral, severity score, the necessity of Achilles tenotomy, family educational, or income level did not reveal any significant correlation with the recurrence risk. Noncompliance with the orthotic use showed a significant correlation with the recurrence rate

Misoprostol management of miscarriage is only now becoming widely used in Australia. To review the efficacy, safety and the popularity of outpatient sublingual misoprostol in empty sac/missed miscarriage management over its first two years of availability in a metropolitan Australian hospital. A retrospective cohort review was undertaken of women choosing sublingual misoprostol 600 μg (three tablets) × three doses for miscarriage management. Principal outcomes assessed were miscarriage resolution without the need for curettage and complications. Additionally, the relative popularity of misoprostol versus surgery by place of birth and over time, and the return of pregnancy tissue for histology were analysed. Between 1 December 2012 and 30 November 2014, 279 women chose sublingual misoprostol for nonurgent miscarriage management, while 420 chose surgery (40 and 60%, respectively). Of the misoprostol cohort, 269 had complete data; 239 of 269 (88.8%) had resolution without curettage, nine (3.3%) had acute curettage, 21 (7.8%) had nonacute curettage, 30 (11.15%) had unplanned emergency department presentation, 11 (4.1%) had unplanned admission, three (1.1%) had blood transfusion and one (0.4%) had an infection requiring admission. Misoprostol was as popular with Australian-born as overseas-born women; 53.5% of patients returned histopathology specimens; one (0.7%) demonstrated partial hydatidiform mole. Outpatient management of missed/empty gestational sac miscarriage using sublingual misoprostol is associated with a high rate of avoiding curettage and the low rate of complication. It is equally popular with Australian-born and overseas-born women. Just over 50% returned pregnancy tissue for analysis. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

We studied changes in mean gestational sac diameter (MSD) and embryonic crown-rump length (CRL) in intrauterine pregnancies of uncertain viability (IPUVs). We aimed to establish cut-off values for MSD and CRL growth that could be definitively associated with either viability or miscarriage, and to establish the relationship between growth in MSD and appearance of embryonic structures in the gestational sac. One thousand and sixty consecutive IPUVs were recruited prospectively from four London University hospitals: 462 with no yolk sac or embryo, 419 with a yolk sac but no embryo, and 179 with an embryo but no heartbeat visible. IPUV was defined as an empty gestational sac with or without a yolk sac but no embryo seen with MSD < 20 or < 30 mm (depending on center) or an embryo with no heartbeat and CRL < 6 mm or < 8 mm (depending on center). Scans were repeated 7-14 days later. The endpoint was viability at first-trimester screening ultrasonography between 11 and 14 weeks. Change in MSD and CRL between the first and second scans of each pregnancy was compared with respect to viability and appearance of embryonic structures using the two-sample t-test. The study included 359 pregnancies in which a gestational sac with or without embryo was identified at the follow-up scan 7-14 days later. Of these, 192 were viable and 167 non-viable at the 11-14-week scan. MSD growth was significantly higher in viable than non-viable pregnancies (mean 1.003 vs. 0.503 mm/day; P < 0.001, 95% CI of difference 0.403-0.596). A difference in CRL growth was found between the two groups (mean 0.673 vs. 0.148 mm/day; P < 0.001, 95% CI of difference 0.345-0.703). MSD growth of 0.6 mm/day was associated with a specificity for diagnosing miscarriage of 90.1%, a sensitivity of 61.7% and 19 false-positive test results. A cut-off of CRL growth rate of 0.2 mm/day gave a sensitivity of 76.3% and there were no false-positive test results for miscarriage. On repeat scan the failure of either a yolk sac

To compare the performance of traditional G-banding karyotyping with that of copy number variation sequencing (CNV-Seq) for detection of chromosomal abnormalities associated with miscarriage. Products of conception (POC) were collected from spontaneous miscarriages. Chromosomal abnormalities were detected using high-resolution G-banding karyotyping and CNV sequencing. Quantitative fluorescent polymerase chain reaction analysis of maternal and POC DNA for short tandem repeat (STR) markers was used to both monitor maternal cell contamination and confirm the chromosomal status and sex of the miscarriage tissue. A total of 64 samples of POC, comprising 16 with an abnormal and 48 with a normal karyotype, were selected and coded for analysis by CNV-Seq. CNV-Seq results were concordant for 14 (87.5%) of the 16 gross chromosomal abnormalities identified by karyotyping, including 11 autosomal trisomies and three sex chromosomal aneuploidies (45,X). Of the two discordant results, a 69,XXX polyploidy was missed by CNV-Seq, although supporting STR marker analysis confirmed the triploidy. In contrast, CNV-Seq identified a sample with 45,X karyotype as a 45,X/46,XY mosaic. In the remaining 48 samples of POC with a normal karyotype, CNV-Seq detected a 2.58-Mb 22q deletion associated with DiGeorge syndrome and nine different smaller CNVs of no apparent clinical significance. CNV-Seq used in parallel with STR profiling is a reliable and accurate alternative to karyotyping for identifying chromosome copy number abnormalities associated with spontaneous miscarriage.

The subtalar joint is commonly affected in children with juvenile idiopathic arthritis and is challenging to treat percutaneously. To describe the technique for treating the subtalar joint with US-guided corticosteroid injections in children and young adults with juvenile idiopathic arthritis and to evaluate the safety of the treatment. We retrospectively analyzed 122 patients (age 15 months-29 years) with juvenile idiopathic arthritis who were referred by a pediatric rheumatologist for corticosteroid injection therapy for symptoms related to the hindfoot or ankle. In these patients the diseased subtalar joint was targeted for therapy, often in conjunction with adjacent affected joints or tendon sheaths of the ankle. We used a protocol based on age, weight and joint for triamcinolone hexacetonide or triamcinolone acetonide dose prescription. We describe the technique for successful treatment of the subtalar joint. A total of 241 subtalar joint corticosteroid injections were performed under US guidance, including 68 repeat injections for recurrent symptoms in 26 of the 122 children and young adults. The average time interval between repeat injections was 24.8 months (range 2.2-130.7 months, median 14.2 months). Subcutaneous tissue atrophy and skin hypopigmentation were the primary complications observed. These complications occurred in 3.9% of the injections. With appropriate training and practice, the subtalar joint can be reliably and safely targeted with US-guided corticosteroid injection to treat symptoms related to juvenile idiopathic arthritis.

Pregnancy failure and heritable thrombophilia.

PubMed

Middeldorp, Saskia

2007-04-01

Heritable thrombophilia is associated with an increased risk for pregnancy failure, defined as sporadic and recurrent miscarriage, late fetal loss, and other vascular pregnancy complications such as preeclampsia and intrauterine growth retardation. The pathogenesis is likely to include effects on trophoblast differentiation and not solely hypercoagulability. This is in line with the observation that most recurrent miscarriages occur early. Therapeutic options include aspirin as well as low-molecular-weight heparin. However, in women with heritable thrombophilia and unexplained recurrent pregnancy loss, evidence is not available as published trials have not used an adequate comparator (no treatment or placebo). Currently, randomized controlled trials with no treatment or placebo are being carried out and results should be awaited before implementing a potentially harmful intervention in pregnant women with heritable thrombophilia and a history of pregnancy failure. Both infertility and pregnancy failure are extremely distressing for couples with the desire to have children. Pregnancy failure comprises (recurrent) early miscarriage, as well as late pregnancy loss. The role of heritable thrombophilia in pregnancy failure is reviewed, with a focus on recurrent miscarriage, in terms of epidemiology, etiology, and potential therapeutic implications.

Introduction To investigate possible associations between miscarriage and occupational exposures in the Shanghai Textile Industry. Methods We conducted a retrospective cohort study of miscarriages among 1,752 women in the Shanghai textile industry. Reproductive history was self-reported by women and occupational work histories were collected from factory personnel records. Occupational exposures were assigned by linking work history information to an industry-specific job-exposure matrix informed by factory-specific textile process information and industrial hygiene assessments. Estimates of cotton dust and endotoxin exposure were also assigned. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by multivariate logistic regression, with adjustment for age at pregnancy, education level, smoking status of woman and spouse, use of alcohol, and woman’s year of birth. Results An elevation in risk of a spontaneously aborted first pregnancy was associated with exposure to synthetic fibers (1.89, 95% CI: 1.20–3.00) and mixed synthetic and natural fibers (3.31, 95% CI: 1.30–8.42). No increased risks were observed for women working with solvents, nor were significant associations observed with quantitative cotton dust or endotoxin exposures. Associations were robust and similar when all pregnancies in a woman’s reproductive history were considered. Conclusions Occupational exposure to synthetic fibers may cause miscarriages, and this possibility should be the subject of further investigation. PMID:18805889

Discrete potentials (DPs) have been recorded and targeted as the site of ablation of the outflow tract arrhythmias. The aim of the present study was to investigate the significance of DPs with respect to mapping and ablation for idiopathic outflow tract premature ventricular contractions (PVCs) or ventricular tachycardias (VTs). Seventeen consecutive patients with idiopathic right or left ventricular outflow tract PVCs/VTs who underwent radiofrequency catheter ablation were included. Intracardiac electrograms during the mapping and ablation were analysed. During sinus rhythm, sharp high-frequency DPs that displayed double or multiple components were recorded following or buried in the local ventricular electrograms in all of the 17 patients, peak amplitude 0.51 ± 0.21 mV. The same potential was recorded prior to the local ventricular potential of the PVCs/VTs. Spontaneous reversal of the relationship of the DPs to the local ventricular electrogram during the arrhythmias was noted. The DPs were related to a region of low voltage showed by intracardiac high-density contact mapping. At the sites with DPs, lower unipolar and bipolar ventricular voltage of sinus beats were noted compared with the adjacent regions without DPs (unipolar: 6.1 ± 1.8 vs. 8.3 ± 2.3 mV, P < 0.05; bipolar: 0.62 ± 0.45 vs. 1.03 ± 0.60 mV, P < 0.05). The targeted DPs were still present in 12 patients after successful elimination of the ectopies. Discrete potentials were not present in seven controls. Discrete potentials and related low-voltage regions were common in idiopathic outflow tract ventricular arrhythmias. Discrete potential- and substrate-guided ablation strategy will help to reduce the recurrence of idiopathic outflow tract arrhythmias. Published on behalf of the European Society of Cardiology.

Idiopathic Inflammatory Myopathies

PubMed Central

Dimachkie, Mazen M.; Barohn, Richard J.

2012-01-01

The idiopathic inflammatory myopathies are a group of rare disorders including polymyositis (PM), dermatomyositis (DM), and autoimmune necrotizing myopathies (NMs). The idiopathic inflammatory myopathies share many similarities. They present acutely, subacutely, or chronically with marked proximal and symmetric muscle weakness, except for associated distal and asymmetric weakness in inclusion body myositis. The idiopathic inflammatory myopathies also share a variable degree of creatine kinase (CK) elevation and a nonspecifically abnormal electromyogram demonstrating an irritative myopathy. The muscle pathology demonstrates inflammatory exudates of variable distribution within the muscle fascicle. Despite these similarities, the idiopathic inflammatory myopathies are a heterogeneous group. The overlap syndrome (OS) refers to the association of PM, DM, or NM with connective tissue disease, such as scleroderma or systemic lupus erythematosus. In addition to elevated antinuclear antibodies (ANA), patients with OS may be weaker in the proximal arms than the legs mimicking the pattern seen in some muscular dystrophies. In this review, we focus on DM, PM, and NM and examine current and promising therapies. PMID:23117947

Idiopathic trigeminal neuralgia (ITN) is a common pain disease in elderly people. Many methods have been used to alleviate the pain of patients, but few studies in the literature have compared the effect of nerve combing and percutaneous radiofrequency thermocoagulation. The purpose of this study was to describe and evaluate the clinical outcome of idiopathic trigeminal neuralgia after nerve combing (NC) and compare them with those obtained using percutaneous radiofrequency thermocoagulation (RF). The study included 105 idiopathic trigeminal neuralgia patients with similar symptom, age and underlying disease, which were divided into two groups. One group was treated by nerve combing (50 patients), the other by RF (55 cases). All patients were considered medical failures prior to the surgeries. A questionnaire was used to assess the long-term outcomes: pain relief, recurrence, complication and need for additional treatment. The median duration of follow-up in both groups was 90 months. Satisfactory relief was noted in 41 patients (82%), 5 patients (10%) initially experienced pain relief, then recurred, and four patients (8%) were designated poor among the group NC. In the group RF, satisfactory relief was noted in 42 patients (76.4%). There were eight "pain free with recurrence patients (14.5%) and 5 poor cases (9.1%). No statistically significant differences existed in the outcomes between both groups (p>0.05). Postoperative morbidity included dysesthesia, diplopia, partial facial nerve palsy, hearing loss, tinnitus, cerebrospinal fluid leak, meningitis and mortality. Nerve combing and RF are both satisfactory treatment strategies for patients with ITN. Because of the higher risk of sensory morbidity and surgical risk as open surgery, RF is preferred as the recommended procedure for patients with ITN.

A case is reported of a 20-year-old woman with generalized severe gingival overgrowth covering almost all of the teeth with diastemata, diagnosed as idiopathic gingival fibromatosis. After initial therapy, the patient underwent surgery consisting of a full-mouth internal beveled gingivectomy. Postoperatively, the maxillary anterior teeth spontaneously moved to almost optimal positions. Removing the cause by gingivectomy can lead to spontaneous correction of the pathologic tooth migration. With supportive periodontal treatment, the patient showed no recurrence of gingival enlargement or repositioning of the teeth at the 5-year follow-up.

Identification of the first recurrent PAR1 deletion in Léri-Weill dyschondrosteosis and idiopathic short stature reveals the presence of a novel SHOX enhancer.

SHOX, located in the pseudoautosomal region 1 (PAR1) of the sexual chromosomes, encodes a transcription factor implicated in human growth. Defects in SHOX or its enhancers have been observed in ∼60% of Leri-Weill dyschondrosteosis (LWD) patients, a skeletal dysplasia characterised by short stature and/or the characteristic Madelung deformity, and in 2-5% of idiopathic short stature (ISS). To identify the molecular defect in the remaining genetically undiagnosed LWD and ISS patients, this study screened previously unanalysed PAR1 regions in 124 LWD and 576 ISS probands. PAR1 screening was undertaken by multiplex ligation dependent probe amplification (MLPA). Copy number alterations were subsequently confirmed and delimited by locus-specific custom-designed MLPA, array comparative genomic hybridisation (CGH) and breakpoint junction PCR/sequencing. A recurrent PAR1 deletion downstream of SHOX spanning 47543 bp with identical breakpoints was identified in 19 LWD (15.3%) and 11 ISS (1.9%) probands, from 30 unrelated families. Eight evolutionarily conserved regions (ECRs 1-8) identified within the deleted sequence were evaluated for SHOX regulatory activity by means of chromosome conformation capture (3C) in chicken embryo limbs and luciferase reporter assays in human U2OS osteosarcoma cells. The 3C assay indicated potential SHOX regulatory activity by ECR1, which was subsequently confirmed to act as a SHOX enhancer, operating in an orientation and position independent manner, in human U2OS cells. This study has identified the first recurrent PAR1 deletion in LWD and ISS, which results in the loss of a previously uncharacterised SHOX enhancer. The loss of this enhancer may decrease SHOX transcription, resulting in LWD or ISS due to SHOX haploinsufficiency.

Ectopic pregnancies, miscarriages and hydatidiform moles are the major types of pathological pregnancies in the early gestations of pregnancy and constitute an important public health problem. The trends and incidences of these pathological pregnancies may vary by ethnicity and geographical regions. This has not been fully investigated in the Chinese population. In this study we retrospectively report the trends of pathological pregnancies in Chinese population. Data on 22,511 women with ectopic pregnancy, hydatidiform mole and miscarriage were collected from the largest obstetrics and gynaecology hospital in China from 2003 to 2013. Data included age at diagnosis and the annual number of women with diagnosed ectopic pregnancy, hydatidiform mole and miscarriage. The total number of ectopic pregnancy, hydatidiform mole and miscarriage was increased 3.5folds in 2013 compared to 2003. Ectopic pregnancy is the leading pathological pregnancy and miscarriage is increasing at a greater rate among the pathological pregnancies. The median age of women with hydatidiform mole at diagnosis significantly increased from 25.5 years to 29 years (p = 0.002), however the median age for other pathological pregnancies was not different between 2003 and 2013. The number of women with hydatidiform mole at diagnosis who were over 40 years old has increased. The mean maternal age is increased from 28.1 years old in 2003 to 29.4 years old in 2013 in this hospital. We speculate that the increased maternal age may contribute to the increase in these pathological pregnancies between 2003 and 2013 in China.

Neurocysticercosis (NCC), a neglected tropical disease, inflicts substantial health and economic costs on people living in endemic areas such as India. Nevertheless, accurate diagnosis using brain imaging remains poorly accessible and too costly in endemic countries. The goal of this study was to test if blood monocyte gene expression could distinguish patients with NCC-associated epilepsy, from NCC-negative imaging lesion-free patients presenting with idiopathic epilepsy or idiopathic headaches. Patients aged 18 to 51 were recruited from the Department of Neurological Sciences, Christian Medical College and Hospital, Vellore, India, between January 2013 and October 2014. mRNA from CD14+ blood monocytes was isolated from 76 patients with NCC, 10 Recovered NCC (RNCC), 29 idiopathic epilepsy and 17 idiopathic headaches patients. A preliminary microarray analysis was performed on six NCC, six idiopathic epilepsy and four idiopathic headaches patients to identify genes differentially expressed in NCC-associated epilepsy compared with other groups. This analysis identified 1411 upregulated and 733 downregulated genes in patients with NCC compared to Idiopathic Epilepsy. Fifteen genes up-regulated in NCC patients compared with other groups were selected based on possible relevance to NCC, and analyzed by qPCR in all patients' samples. Differential gene expression among patients was assessed using linear regression models. qPCR analysis of 15 selected genes showed generally higher gene expression among NCC patients, followed by RNCC, idiopathic headaches and Idiopathic Epilepsy. Gene expression was also generally higher among NCC patients with single cyst granulomas, followed by mixed lesions and single calcifications. Expression of certain genes in blood monocytes can distinguish patients with NCC-related epilepsy from patients with active Idiopathic Epilepsy and idiopathic headaches. These findings are significant because they may lead to the development of new tools to

Intra-articular corticosteroid injections are a safe and effective treatment for patients with juvenile idiopathic arthritis. The potential scope of care in ultrasound-guided corticosteroid therapy in children and a joint-based corticosteroid dose protocol designed to optimize interdisciplinary care are not found in the current literature. The purpose of this study was to report the spectrum of care, technique and safety of ultrasound-guided corticosteroid injection therapy in patients with juvenile idiopathic arthritis and to propose an age-weight-joint-based corticosteroid dose protocol. A retrospective analysis was performed of 198 patients (ages 21 months to 28 years) referred for treatment of juvenile idiopathic arthritis with corticosteroid therapy. Symptomatic joints and tendon sheaths were treated as prescribed by the referring rheumatologist. An age-weight-joint-based dose protocol was developed and utilized for corticosteroid dose prescription. A total of 1,444 corticosteroid injections (1,340 joints, 104 tendon sheaths) were performed under US guidance. Injection sites included small, medium and large appendicular skeletal joints (upper extremity 497, lower extremity 837) and six temporomandibular joints. For patients with recurrent symptoms, 414 repeat injections were performed, with an average time interval of 17.7 months (range, 0.5-101.5 months) between injections. Complications occurred in 2.6% of injections and included subcutaneous tissue atrophy, skin hypopigmentation, erythema and pruritis. US-guided corticosteroid injection therapy provides dynamic, precise and safe treatment of a broad spectrum of joints and tendon sheaths throughout the entire pediatric musculoskeletal system. An age-weight-joint-based corticosteroid dose protocol is effective and integral to interdisciplinary care of patients with juvenile idiopathic arthritis.

Idiopathic granulomatous mastitis (IGM), is a rare entity of chronic inflammatory disorder of the breast of unknown etiology. Very few cases have been described so far, almost exclusively in women. Here we describe a case of IGM in a 53-year-old man presented with a right breast mass, progressively enlarging during the last 6 months. Due to the findings of clinical examination and CT-scan, the suspicion for a potentially malignant lesion was given and the decision for surgical resection was made. Microscopic analysis of the specimen showed non-caseating granulomas around mammary lobules, findings compatible with IGM. The patient is recurrence-free at 18-month follow-up. IGM is a rare benign inflammatory breast disease, usually seen in females of reproductive age. Establishing a diagnosis can be challenging for a surgeon and requires a high index of suspicion as most patients are initially misdiagnosed by their primary care physicians. Steroids and immunosuppressive drugs are considered as fundamental treatment modalities but they are correlated with increased rates of disease response and recurrence. On the contrary, surgical resection demonstrated significantly superior results compared to steroid-alone treatment in terms of recurrence and post-treatment recovery. PMID:28856149

Familial or Sporadic Idiopathic Scoliosis – classification based on artificial neural network and GAPDH and ACTB transcription profile

PubMed Central

2013-01-01

Background Importance of hereditary factors in the etiology of Idiopathic Scoliosis is widely accepted. In clinical practice some of the IS patients present with positive familial history of the deformity and some do not. Traditionally about 90% of patients have been considered as sporadic cases without familial recurrence. However the exact proportion of Familial and Sporadic Idiopathic Scoliosis is still unknown. Housekeeping genes encode proteins that are usually essential for the maintenance of basic cellular functions. ACTB and GAPDH are two housekeeping genes encoding respectively a cytoskeletal protein β-actin, and glyceraldehyde-3-phosphate dehydrogenase, an enzyme of glycolysis. Although their expression levels can fluctuate between different tissues and persons, human housekeeping genes seem to exhibit a preserved tissue-wide expression ranking order. It was hypothesized that expression ranking order of two representative housekeeping genes ACTB and GAPDH might be disturbed in the tissues of patients with Familial Idiopathic Scoliosis (with positive family history of idiopathic scoliosis) opposed to the patients with no family members affected (Sporadic Idiopathic Scoliosis). An artificial neural network (ANN) was developed that could serve to differentiate between familial and sporadic cases of idiopathic scoliosis based on the expression levels of ACTB and GAPDH in different tissues of scoliotic patients. The aim of the study was to investigate whether the expression levels of ACTB and GAPDH in different tissues of idiopathic scoliosis patients could be used as a source of data for specially developed artificial neural network in order to predict the positive family history of index patient. Results The comparison of developed models showed, that the most satisfactory classification accuracy was achieved for ANN model with 18 nodes in the first hidden layer and 16 nodes in the second hidden layer. The classification accuracy for positive Idiopathic

Through a cross-sectional study design, 326 women with a history of miscarriage were examined for anti-Toxoplasma gondii IgG and IgM antibodies in Durango City, Mexico. Prevalence association with sociodemographic, clinical, and behavioral characteristics in women with miscarriage was also investigated. Twenty-two (6.7%) of the 326 women studied had anti-T. gondii IgG antibodies and two (0.6%) were also positive for anti-T. gondii IgM antibodies. Seroprevalence of T. gondii infection was not influenced by age, birth place, occupation, educational level, or socioeconomic status. In contrast, logistic regression showed that T. gondii exposure was associated with consumption of raw or undercooked meat (OR = 6.84; 95% CI: 1.04-44.95; P = 0.04) and consumption of chicken brains (OR = 18.48; 95% CI: 1.26-269.43; P = 0.03). This is the first study on the seroepidemiology of T. gondii infection in women with a history of miscarriage in Northern Mexico. Of interest, we also observed an association of T. gondii exposure with consumption of chicken brains. Contributing factors for T. gondii exposure found in the present study should be taken into consideration for public health measures to avoid infection with T. gondii and its sequelae.

Focal segmental glomerulosclerosis (FSGS) is one of the most common patterns of glomerular injury encountered in human renal biopsies. Epithelial hyperplasia, which can be prominent in FSGS, has been attributed to dedifferentiation and proliferation of podocytes. Based on observations in a mouse model of FSGS, we pointed to the role of parietal epithelial cells (PECs). In the present study we investigated the relative role of PECs and podocytes in human idiopathic FSGS. We performed a detailed study of lesions from a patient with recurrent idiopathic FSGS by serial sectioning, marker analysis and three-dimensional reconstruction of glomeruli. We have studied the expression of markers for podocytes, PECs, mesangial cells, endothelium, and myofibroblasts. We also looked at proliferation and composition of the deposited extracellular matrix (ECM). We found that proliferating epithelial cells in FSGS lesions are negative for podocyte and macrophage markers, but stain for PEC markers. The composition of the matrix deposited by these cells is identical to Bowman's capsule. Our study demonstrates that PECs are crucially involved in the pathogenesis of FSGS lesions.

Idiopathic lobular granulomatous mastititis is a rare inflammatory disease of the breast. Since the clinical manifestations simulate those of mammary malignancy, it is often misdiagnosed. We report a case in a 25 yrs old Egyptian woman who had presented with complaint of a painful mass in her right breast of 3 months duration. Clinical and radiological examinations were indeterminate of its nature and the diagnosis was established by histopathogical, microbiological and serological tests. Review of relevant literature mention the features of Idiopathic lobular granulomatous mastititis, which impose significant challenge on clinical, radiological and even histopathological diagnosis. These correlate well with our case scenario also. Complete resection of the lesions and/or administration of steroids are usually the recommended treatment, however about 38% patients may experience recurrence. Hence proper post treatment follow up is mandatory. Awareness among the clinicians, radiologists and pathologists about this disease entity is required and multi disciplinary approach is imperative to establish the diagnosis. We hope to convey these facts through this article with the review of relevant literature.

Recurrent pregnancy loss (RPL) is defined by two or more failed pregnancies and accounts for only 1-5% of pregnancy failures. Treatment options for unexplained RPL (uRPL) are limited. Previous studies suggest a link between delayed implantation and pregnancy loss. Based on this, a timely signal for rescue of the corpus luteum (CL) using human chorionic gonadotrophin (HCG) could improve outcomes in women with uRPL. This retrospective cohort study included 98 subjects with uRPL: 45 underwent 135 monitored cycles without HCG support; and 53 underwent 142 cycles with a single mid-luteal HCG injection. Based on Log-rank Mantel-Cox survival curves, miscarriage rate and time to pregnancy decreased in the HCG group (P = 0.0005). Women receiving luteal HCG support had an increased chance of an ongoing pregnancy compared with those not receiving it (RR = 2.4; 95% CI 1.4-3.6; number need to treat (NNT) = 7; 95% CI 4-18). Subjects receiving HCG support had a significant absolute risk reduction (ARR) of miscarriage (P < 0.001; ARR = 11.5%; 95% CI 3.6-19.5; NNT = 9(5-27). These data suggest restoration of synchrony and CL support improves outcomes in women with RPL. Further randomized controlled trials of luteal-phase HCG in women with RPL appears warranted.

The Ponseti method has become the treatment standard for idiopathic clubfoot. Deformity recurrence is most commonly attributed to premature abandonment of the requisite abduction orthosis. A study in 2009 from our center revealed a high rate of deformity recurrence in our patient population. It was surmised that the importance of bracing to maintain correction had not been adequately communicated to some families, especially Native Americans. As a result, the principal investigator developed a different communication protocol for parents of infants. All children treated for clubfoot at the University of New Mexico Carrie Tingley Hospital, Albuquerque, NM, from 2008 to 2010 were reviewed. They were compared with a historical control group from this institution, the subjects of the 2009 study, and were analyzed for the rate of recurrence and Pirani score improvement. Our study cohort comprised 69 infants (104 clubfeet), all of whom were treated with the new communication style. The recurrence rate for the new communication paradigm was 2.88% compared with 18.2% in the control group (P<0.001). The Pirani score improvement was 4.0 in the treatment group compared with 3.5 in the control group (P=0.001). Native American recurrence was zero in the treatment group and 41% in the control group (P=0.011). A positive, rather than a negative communication style, emphasis on the brace as the most important aspect of treatment, and a more culturally sensitive family education paradigm, resulted in a lower rate of deformity recurrence when treating children with clubfeet using the Ponseti method.

Idiopathic granulomatous mastitis (IGM) is an uncommon chronic inflammatory lesion of the breast with an uncertain optimal treatment regimen, the physical examination, and radiologic features of which may be confused with breast carcinoma. In this study, we aimed to describe the clinicopathologic characteristics of 33 patients who admitted to our breast policlinic and took the diagnosis of granulomatous (idiopathic and non-idiopathic) mastitis, and report the place of corticosteroids and the timing of surgery in the treatment of patients with IGM. The clinical features of 33 patients who presented to our breast policlinic with the complaint of breast mass and reached the final diagnosis of GM between March 2005 and October 2009 were reported. The most common symptoms were mass (n: 27) and pain (n: 11). Ultrasonography (USG) and biopsy were performed in all of the patients. Mammography (MMG) was performed in 9, and magnetic resonance imaging (MRI) in 10 patients. The diagnosis of idiopathic lobular granulomatous mastitis (ILGM) was made in 25 patients and tuberculous mastitis (non-idiopathic GM) in the remaining 8 patients. Twenty-four patients received steroid treatment except one who was pregnant. After giving birth, she also received steroids. One of the patients who developed recurrence after 11 months repeated the steroid therapy. Eight patients with tuberculous mastitis were placed on a regimen of antituberculosis therapy for 6 months. In the diagnosis of IGM, physical examination, USG, MMG, and even MRI alone may sometimes not be enough. They should be discussed altogether and the treatment should begin after definitive histopathologic result. Fine needle aspiration biopsy for cytology will result in a high level of diagnostic accuracy, however, core biopsy will reinforce the exact result. Corticosteroid therapy has been shown to be efficacious for IGM, but in the existence of complications such as abscess formation, fistulae, and persistent wound infection

Summary Background Idiopathic granulomatous mastitis (IGM) is an uncommon chronic inflammatory disease of the breast with uncertain optimal treatment regimen. In this study, our purpose was to report our clinical experience with 74 IGM patients who were treated wide local excision with or without steroid therapy. Patients and Method 74 cases diagnosed histologically as IGM were identified from surgical and pathological records between January 1995 and January 2012. Group 1 (surgery-only group) comprised 53 patients, and the 21 patients in group 2 were treated with corticosteroids prior to surgical treatment (steroid-and-surgery group). Results Follow-up data were complete for 67 (91.7%) of the 73 patients. Recurrence developed in 4 (7.5%) patients in the surgery-only group, while there was no recurrence in the steroid-and-surgery group; the difference was not statistically significant (p = 0.19). Conclusion Systemic steroid therapy with surgical resection is the recommended first-line treatment strategy for IGM. PMID:24944554

Rosai-Dorfman disease (RDD) is a rare, idiopathic, benign histioproliferative disorder. Extranodal involvement is seen in around 25-40% of patients. Central nervous system manifestation of RDD is uncommon and suprasellar location of the lesion is a distinct rarity. Surgery is the cornerstone of management of intracranial RDD. However, tumor recurrence or regrowth is a potential problem. Hence, low dose conformal radiotherapy (RT) should be considered in patients undergoing sub-total resection or having unresectable recurrent disease. Though cranial RT usually leads to satisfactory improvement of symptoms and long-term disease stabilization or regression, in few patients there may be an eventual progression of disease for which systemic chemotherapy may be considered. We have highlighted the salient features of this enigmatic disease by citing a case of a 50-year-old male patient with suprasellar RDD treated by maximal safe surgery and deferred radiation therapy on progression.

To determine what percentage of diabetes insipidus (DI) in childhood is idiopathic and to assess the natural history of idiopathic DI. We conducted a retrospective chart review of 105 patients with DI who were born or had DI diagnosed between 1980-1989 at 3 medical centers. A second cohort of 30 patients from 6 medical centers in whom idiopathic DI was diagnosed after 1990 was evaluated retrospectively for subsequent etiologic diagnoses and additional hypothalamic/pituitary deficiencies and prospectively for quality of life. In the first cohort, 11% of patients had idiopathic DI. In the second cohort, additional hypothalamic/pituitary hormone deficiencies developed in 33%, and 37% received an etiologic diagnosis for DI. Health-related quality of life for all the patients with idiopathic DI was comparable with the healthy reference population. Only a small percentage of patients with DI will remain idiopathic after first examination. Other hormone deficiencies will develop later in one-third of those patients, and slightly more than one-third of those patients will have an etiology for the DI diagnosed. Long-term surveillance is important because tumors have been diagnosed as long as 21 years after the onset of DI. Quality of life for these patients is as good as the reference population.

Chronic urticaria is the most common skin diseases, characterized by chronic cutaneous lesions which severely debilitates patients in several aspects of their everyday life. Vitamin D is known to exert several actions in the immune system and to influence function and differentiation of mast cells, central role players in the pathogenesis of chronic idiopathic urticaria. This study was performed to evaluate the relationship between vitamin D levels and susceptibility to chronic idiopathic urticaria. One hundred and fourteen patients with chronic idiopathic urticaria were recruited in this study along with one hundred and eighty seven sex-matched and age-matched healthy volunteers as the control group. For each patient, urticaria activity score was calculated and autologous serum skin test was done. Vitamin D metabolic statue was measured in serum as 25 hydroxyvitamin D using enzyme immunoassay method. Patients with chronic idiopathic urticaria significantly showed lower levels of vitamin D. Vitamin D deficiency was significantly associated with increased susceptibility to chronic idiopathic urticaria. There was a significant positive correlation between vitamin D levels and urticaria activity score. This study showed that patients with chronic idiopathic urticaria had reduced levels of vitamin D, while vitamin D deficiency could increase susceptibility to chronic idiopathic urticaria.

Idiopathic ventricular tachycardia and fibrillation.

Belhassen, B; Viskin, S

Important data have recently been added to our understanding of sustained ventricular tachyarrhythmias occurring in the absence of demonstrable heart disease. Idiopathic ventricular tachycardia (VT) is usually of monomorphic configuration and can be classified according to its site of origin as either right monomorphic (70% of all idiopathic VTs) or left monomorphic VT. Several physiopathological types of monomorphic VT can be presently individualized, according to their mode of presentation, their relationship to adrenergic stress, or their response to various drugs. The long-term prognosis is usually good. Idiopathic polymorphic VT is a much rarer type of arrhythmia with a less favorable prognosis. Idiopathic ventricular fibrillation may represent an underestimated cause of sudden cardiac death in ostensibly healty patients. A high incidence of inducibility of sustained polymorphic VT with programmed ventricular stimulation has been found by our group, but not by others. Long-term prognosis on Class IA antiarrhythmic medications that are highly effective at electrophysiologic study appears excellent.

Increasing numbers of reports show the beneficial effects of listening to Mozart music in decreasing epileptiform discharges as well as seizure frequency in epileptic children. There has been no effective method to reduce seizure recurrence after the first unprovoked seizure until now. In this study, we investigated the effect of listening to Mozart K.448 in reducing the seizure recurrence rate in children with first unprovoked seizures. Forty-eight children who experienced their first unprovoked seizure with epileptiform discharges were included in the study. They were randomly placed into treatment (n = 24) and control (n = 24) groups. Children in the treatment group listened to Mozart K.448 daily before bedtime for at least six months. Two patients in the treatment group were excluded from analysis due to discontinuation intervention. Finally, forty-six patients were analyzed. Most of these patients (89.1%) were idiopathic in etiology. Seizure recurrence rates and reduction of epileptiform discharges were compared. The average follow-up durations in the treatment and control groups were 18.6 ± 6.6 and 20.1 ± 5.1 months, respectively. The seizure recurrence rate was estimated to be significantly lower in the treatment group than the control group over 24 months (37.2% vs. 76.8%, p = 0.0109). Significant decreases in epileptiform discharges were also observed after 1, 2, and 6 months of listening to Mozart K.448 when compared with EEGs before listening to music. There were no significant differences in gender, mentality, seizure type, and etiology between the recurrence and non-recurrence groups. Although the case number was limited and control music was not performed in this study, the study revealed that listening to Mozart K.448 reduced the seizure recurrence rate and epileptiform discharges in children with first unprovoked seizures, especially of idiopathic etiology. We believe that Mozart K.448 could be a promising alternative treatment in patients with

A prospective and controlled comparative study. To verify the difference in morphologic appearance between a group of adolescents with progressive adolescent idiopathic scoliosis and a control group of normal adolescents. In a previous retrospective study, the possibility of a relation between progressive adolescent idiopathic scoliosis and specific morphotypes was demonstrated. Fifty-two adolescent girls with progressive adolescent idiopathic scoliosis were compared with an age-matched control group of 62 unaffected girls using a classification technique based on morphologic somatotypes. Morphotypes were evaluated with standardized pre-established criteria based on Sheldon's technique. Patients with progressive adolescent idiopathic scoliosis showed significantly less mesomorphism (mean value of 0.88 +/- 0.51) than control girls (mean value of 1.72 +/- 0.52). Adolescent girls with progressive adolescent idiopathic scoliosis have a morphologic somatotype that is different from the normal adolescent population. Subjects with progressive adolescent idiopathic scoliosis are significantly less mesomorphic than control girls. This observation may be of value as a predictive factor for early identification of subjects with adolescent idiopathic scoliosis at greater risk of progression.

Purpose Provide an update on various features of idiopathic intracranial hypertension. Design Perspective. Methods Selected articles on the epidemiology, clinical and imaging features, natural history, pathophysiology, and treatment of idiopathic intracranial hypertension were reviewed and interpreted in the context of the authors’ clinical and research experience. Results Idiopathic intracranial hypertension is primarily a disease of obese women of childbearing age, but it can affect patients of any weight, sex, and age. Although a relatively rare disorder, idiopathic intracranial hypertension’s associated costs in the U.S. entail hundreds of millions of dollars. Even following treatment, headaches are frequently persistent and may require the continued involvement of a neurologist. Quality of life reductions and depression are common among idiopathic intracranial hypertension patients. However, visual dysfunction, especially visual field abnormalities, represents the major morbidity of this disorder, and serial automated perimetry remains the primary mode of patient monitoring. Patients who are men, black, very obese, or anemic are at higher risk of visual loss. Vitamin A metabolism, adipose tissue as an actively secreting endocrine tissue, and cerebral venous abnormalities are areas of active study regarding idiopathic intracranial hypertension’s pathophysiology. Treatment studies show that lumbar puncture is a valuable treatment (in addition to its crucial diagnostic role) and that weight management is critical. However, open questions remain regarding the efficacy of acetazolamide, CSF diversion procedures, and cerebral venous stenting. Conclusions Many questions remain unanswered about idiopathic intracranial hypertension. Ongoing studies, especially an ongoing NIH-funded clinical trial of acetazolamide, should provide more insight into this important, yet poorly understood syndrome of isolated intracranial hypertension.

Narcolepsy with and without cataplexy, idiopathic hypersomnia with and without long sleep time: a cluster analysis.

PubMed

Šonka, Karel; Šusta, Marek; Billiard, Michel

2015-02-01

The successive editions of the International Classification of Sleep Disorders (ICSD) reflect the evolution of the concepts of various sleep disorders. This is particularly the case for central disorders of hypersomnolence, with continuous changes in terminology and divisions of narcolepsy, idiopathic hypersomnia, and recurrent hypersomnia. According to the ICSD 2nd Edition (ICSD-2), narcolepsy with cataplexy (NwithC), narcolepsy without cataplexy (Nw/oC), idiopathic hypersomnia with long sleep time (IHwithLST), and idiopathic hypersomnia without long sleep time (IHw/oLST) are four, well-defined hypersomnias of central origin. However, in the absence of biological markers, doubts have been raised as to the relevance of a division of idiopathic hypersomnia into two forms, and it is not yet clear whether Nw/oC and IHw/oLST are two distinct entities. With this in mind, it was decided to empirically review the ICSD-2 classification by using a hierarchical cluster analysis to see whether this division has some relevance, even though the terms "with long sleep time" and "without long sleep time" are inappropriate. The cluster analysis differentiated three main clusters: Cluster 1, "combined monosymptomatic hypersomnia/narcolepsy type 2" (people initially diagnosed with IHw/oLST and Nw/oC); Cluster 2 "polysymptomatic hypersomnia" (people initially diagnosed with IHwithLST); and Cluster 3, narcolepsy type 1 (people initially diagnosed with NwithC). Cluster analysis confirmed that narcolepsy type 1 and polysymptomatic hypersomnia are independent sleep disorders. People who were initially diagnosed with Nw/oC and IHw/oLST formed a single cluster, referred to as "combined monosymptomatic hypersomnia/narcolepsy type 2." Copyright © 2014 Elsevier B.V.

The objective of our study was to investigate the clinical value of diagnostic lymphangiography followed by sequential CT examinations in patients with idiopathic chyluria. Thirty-six patients with idiopathic chyluria underwent unipedal diagnostic lymphangiography and then underwent sequential CT examinations. The examinations were reviewed separately by two radiologists. Abnormal distribution of contrast medium, lymphourinary leakages, and retrograde flow were noted, and the range and distribution of lymphatic vessel lesions were recorded. The stage of idiopathic chyluria based on CT findings and the stage based on clinical findings were compared. Therapeutic management and follow-up were recorded. Statistical analyses were performed. Compared with CT studies performed after lymphangiography, diagnostic lymphangiography showed a unique capability to depict lymphourinary leakages in three patients. Lymphourinary fistulas and abnormal dilated lymphatic vessels were found in and around kidney in all patients. CT depicted retrograde flow of lymph fluid in 47.2% of patients. The consistency in staging chyluria based on CT findings and clinical findings was fair (κ = 0.455). Twenty-nine patients underwent conservative therapy, and seven underwent surgery. Surgical therapy was superior to conservative management (no recurrence, 85.7% of patients who underwent surgery vs 62.1% of patients who underwent conservative therapy; p = 0.025). From assessing the drainage of contrast medium on unipedal diagnostic lymphangiography and the redistribution of contrast medium on sequential CT examinations, it is possible to detect the existence of lymphourinary fistulas, the precise location of lymphatic anomalies, the distribution of collateral lymphatic vessels, and hydrodynamic pressure abnormality in the lymph circulation in patients with idiopathic chyluria. CT staging of chyluria provides additional information that can be used to guide therapeutic management.

The aim of the study was to provide a meta-analysis of current literature concerning the natural history of idiopathic scoliosis during growth. A comprehensive search of Medline, Embase, And Scopus databases was conducted up to November 2016. Eligible works were prospective or retrospective studies that enrolled patients with infantile idiopathic scoliosis, juvenile idiopathic scoliosis, or adolescent idiopathic scoliosis, followed up without any treatment from the time of detection. A meta-analysis for proportion was performed. The following studies were grouped per diagnosis: infantile idiopathic scoliosis, juvenile idiopathic scoliosis, and adolescent idiopathic scoliosis. Of the 1797 citations screened, we assessed 61 full-text articles and included 13 of these (2301 participants). Three studies included infantile idiopathic scoliosis patients (347 participants), five studies included a mixed population of juvenile idiopathic scoliosis and adolescent idiopathic scoliosis (1330 participants), and five studies included adolescent idiopathic scoliosis patients only (624 participants). The random pooled estimated progression rate was 49% (95% confidence interval = 1%-97%) for infantile idiopathic scoliosis, 49% in a mixed group of patients affected by juvenile idiopathic scoliosis or adolescent idiopathic scoliosis (95% confidence interval = 19%-79%), and 42% in adolescent idiopathic scoliosis (95% confidence interval = 11%-73%). During growth, idiopathic scoliosis tends to progress in a high percentage of cases. The progression rate varies according to the age at diagnosis, with infantile scoliosis being the most unpredictable. There are many confounders, such as age, Risser sign and baseline Cobb angles that were not consistent among studies, making the data very heterogeneous.

To assess whether the offspring of UK veterans of the first Gulf war are at increased risk of fetal death or congenital malformation. This was a retrospective reproductive cohort study of UK Gulf war veterans and a demographically similar comparison group who were in service at the time but were not deployed to the Gulf. Reproductive history was collected by means of a validated postal questionnaire between 1998 and 2001. In all, 27 959 pregnancies reported by men and 861 pregnancies reported by women were conceived after the first Gulf war and before November 1997. The risk of reported miscarriage was higher among pregnancies fathered by Gulf war veterans than by non-Gulf war veterans (OR = 1.4, 95% CI: 1.3, 1.5). Stillbirth risk was similar in both groups. Male Gulf war veterans reported a higher proportion of offspring with any type of malformation than the comparison cohort (OR = 1.5, 95% CI: 1.3, 1.7). Examination by type of malformation revealed some evidence for increased risk of malformations of the genital system, urinary system (renal and urinary tract), and 'other' defects of the digestive system, musculo-skeletal system, and non-chromosomal (non-syndrome) anomalies. These associations were weakened when analyses were restricted to clinically confirmed conditions. There was little or no evidence of increased risk for other structural malformations, specific syndromes, and chromosomal anomalies. Among female veterans, no effect of Gulf war service was found on the risk of miscarriage. The numbers of stillbirths and malformations reported by women were too small to allow meaningful analyses. We found no evidence for a link between paternal deployment to the Gulf war and increased risk of stillbirth, chromosomal malformations, or congenital syndromes. Associations were found between fathers' service in the Gulf war and increased risk of miscarriage and less well-defined malformations, but these findings need to be interpreted with caution as such outcomes

Rift Valley fever virus is an emerging mosquito-borne virus that causes infections in animals and human beings in Africa and the Arabian Peninsula. Outbreaks of Rift Valley fever lead to mass abortions in livestock, but such abortions have not been identified in human beings. Our aim was to investigate the cause of miscarriages in febrile pregnant women in an area endemic for Rift Valley fever. Pregnant women with fever of unknown origin who attended the governmental hospital of Port Sudan, Sudan, between June 30, 2011, and Nov 17, 2012, were sampled at admission and included in this cross-sectional study. Medical records were retrieved and haematological tests were done on patient samples. Presence of viral RNA as well as antibodies against a variety of viruses were analysed. Any association of viral infections, symptoms, and laboratory parameters to pregnancy outcome was investigated using Pearson's χ 2 test. Of 130 pregnant women with febrile disease, 28 were infected with Rift Valley fever virus and 31 with chikungunya virus, with typical clinical and laboratory findings for the infection in question. 15 (54%) of 28 women with an acute Rift Valley fever virus infection had miscarriages compared with 12 (12%) of 102 women negative for Rift Valley fever virus (p<0·0001). In a multiple logistic regression analysis, adjusting for age, haemorrhagic disease, and chikungunya virus infection, an acute Rift Valley fever virus infection was an independent predictor of having a miscarriage (odds ratio 7·4, 95% CI 2·7-20·1; p<0·0001). This study is the first to show an association between infection with Rift Valley fever virus and miscarriage in pregnant women. Further studies are warranted to investigate the possible mechanisms. Our findings have implications for implementation of preventive measures, and evidence-based information to the public in endemic countries should be strongly recommended during Rift Valley fever outbreaks.

It has been suggested that women with early miscarriage or ectopic pregnancy are best cared for in dedicated units which offer rapid and definitive ultrasonographic and biochemical assessment at the initial review of the patient. To describe the current protocols for the assessment and treatment of women with early miscarriage or ectopic pregnancy as reported by Nigerian Gynecologists, and determine if dedicated early pregnancy services such as Early Pregnancy Assessment Units could be introduced to improve care. A cross-sectional survey of Nigerian Gynecologists attending the 46 th Annual Scientific Conference of the Society of Gynaecology and Obstetrics of Nigeria. This was a questionnaire-based study. Data analysis was by descriptive statistics using Statistical Package for the Social Sciences software, version 17.0 for Windows (IBM Corporation, Armonk, NY, USA). A total of 232 gynecologists working in 52 different secondary and tertiary health facilities participated in the survey. The mean age of the respondents was 42.6 ± 9.1 years (range 28-70 years). The proportion of gynecologists reporting that women with early miscarriage or ectopic pregnancy were first managed within the hospital general emergency room was 92%. The mean reported interval between arrival in hospital and first ultrasound scan was 4.9 ± 1.4 hours (range ½-8 hours). Transvaginal scan was stated as the routine initial imaging investigation by only 17.2% of respondents. Approximately 94.8% of respondents felt that dedicated early pregnancy services were feasible and should be introduced to improve the care of women with early miscarriage and ectopic pregnancy. Reported protocols for managing early miscarriage or ectopic pregnancy in many health facilities in Nigeria appear to engender unnecessary delays and avoidable costs, and dedicated early pregnancy services could be both useful and feasible in addressing these shortcomings in the way women with such conditions are currently managed.

Study Objectives: To review the clinical and polysomnographic characteristics of idiopathic hypersomnia as well as the long-term response to treatment. Setting: The Respiratory Support and Sleep Centre at Papworth Hospital, Cambridge, UK. Patients and Design: A large database of more than 6000 patients with sleep disorders was reviewed. A retrospective study of the clinical and polysomnographic characteristics of 77 patients with idiopathic hypersomnia was performed. Comparison with a similar group of patients with narcolepsy was performed. The response to drug treatment was assessed in 61 patients over a mean follow-up of 3.8 years. Measurements and Results: Idiopathic hypersomnia was 60% as prevalent as narcolepsy. Comparison with a similar group of patients with narcolepsy showed that those with idiopathic hypersomnia were more likely to have prolonged unrefreshing daytime naps, a positive family history, increased slow-wave sleep, and a longer sleep latency on the Multiple Sleep Latency Test. The results of the Multiple Sleep Latency Test were not helpful in predicting disease severity or treatment response. The clinical features were heterogeneous and of variable severity. The majority of patients with idiopathic hypersomnia had symptoms that remained stable over many years, but 11% had spontaneous remission, which was never seen in narcolepsy. Two thirds of patients with idiopathic hypersomnolence had a sustained improvement in daytime somnolence with medication, although a third needed high doses or combinations of drugs. Conclusions: Idiopathic hypersomnolence has characteristic clinical and polysomnographic features but the prolonged latency on the Multiple Sleep Latency Test raises doubt about the validity of this test within the current diagnostic criteria. The disease often responds well to treatment and a substantial minority of patients appear to spontaneously improve. Citation: Anderson KN; Pilsworth S; Sharples LD; Smith IE; Shneerson JM.

To investigate whether idiopathic Horner's syndrome (HS) in Golden Retrievers is an exclusively preganglionic disorder based on denervation hypersensitivity pharmacological testing with phenylephrine. Medical records of dogs presented with HS between 2000 and 2012. Dogs presented with additional ocular or systemic signs were excluded. Clinical data examined included age, sex, duration of clinical signs, ancillary diagnostic test results, and time to mydriasis on topical ocular application of 1% phenylephrine. Lesions were diagnosed as postganglionic (mydriasis within 20 min) or preganglionic (mydriasis between 20 and 45 min). Medical records of 21 dogs of nine different breeds were included. An etiopathogenesis for Horner's syndrome was determined in five dogs, none of which were Golden Retrievers. All diagnoses correlated with pharmacological lesion localization. Ten Golden Retrievers were included (eight male and two female) with a mean age of 8.5 years (range: 4-13). Lesion localization was diagnosed as postganglionic in eight (mean: 10 min [range: 6-18]) and preganglionic in two Golden Retrievers (20 and 24 min). All cases were unilateral and had completely resolved within 15 weeks (range: 11-20). Recurrence was not reported in any of the patients. Idiopathic postganglionic HS was diagnosed in eight of 10 Golden Retrievers contradicting previous reports of a purely preganglionic localization. Etiopathogenesis of canine idiopathic HS remains to be determined; nevertheless, a vascular etiology cannot be excluded. Future studies using magnetic resonance angiography may aid in clarifying the pathogenesis. © 2013 American College of Veterinary Ophthalmologists.

[The influence of previous pregnancy terminations, miscarriages and still-births on the incidence of babies with low birth weight and premature births as well as a somatic classification of newborns].

The influence of previous interruptions, miscarriages and IUFD on the IUGR and preterm rate as well as on the somatic staging (gestational age and birth weight) of the new born is a subject of controversial discussion in the literature. The present paper attempts to quantify these risks of the medical history. 2 282 412 singleton pregnancies of the period 1995 to 2000 were evaluated from the German Perinatal Database. For the analysis 1 065 202 pregnancies (46.7 %) of those mothers without any live birth in the medical history were assessed. To exclude any influence from previous abortions patients with previous miscarriages and IUFDs were excluded. The control collective were new borns whose mothers had suffered neither from miscarriages nor from abortions or IUFD. Previous interruptions, miscarriages and IUFD influence the rate of new borns with low birth weight and increase the rate of prematurity. With increasing numbers of isolated or combined risks in the medical history, the rate of newborns with a low birth weight or with prematurity is increased. The lowest risk was found after one interruption, the highest rate with two or more IUFDs. Interruptions, miscarriages or IUFD are not risk factors for IUGR or SGA. Previous interruptions, miscarriages and IUFD are relevant risk factors for prematurity and are related with low birth weight of the new borns. Pregnant women with such risk factors have to been considered as risk pregnancies and need intensive surveillance.

The objective was to investigate the association between idiopathic recurrent spontaneous abortion (RSA) and 3 SLC19A1 polymorphisms (-43T>C, 80G>A, and 696C>T). DNA from 269 patients with RSA and 125 controls were genotyped for the 3 SLC19A1 single nucleotide polymorphisms (SNPs) by polymerase chain reaction-restriction fragment length polymorphism. Homocysteine and folate levels of 100 patients with RSA were available for analysis. The combination genotypes of SLC19A1 -43TC/80GG, -43TC/80AA, and -43CC/80GA; 80GA/696TT, 80AA/696CC; and -43TC/696CC were less frequent in patients with RSA compared to controls (P < .05 for each). The -43C/80A/696 T and -43T/80G/696C haplotypes were more frequent in patients than controls, whereas -43T/80A/696C, -43C/80A/696C, -43C/80G/696C, -43C/80G/696T, and -43T/80G/696T haplotypes were less frequent in patients (P < .05 for each). The -43T/80G and 80A/696T haplotypes were more frequent in patients, while -43T/80A, -43C/80G, 80A/696C, 80G/696T, and -43C/696C haplotypes occurred less frequently in patients (P < .05 for each). The associations between idiopathic RSA occurrence and SLC19A1 -43T>C/80G>A/696C>T polymorphisms were identified and can be developed as biomarkers for RSA risk.

Longitudinal Analysis of Vaginal Microbiome Dynamics in Women with Recurrent Bacterial Vaginosis: Recognition of the Conversion Process

Bacterial vaginosis (BV) affects ∼30% of women of reproductive age, has a high rate of recurrence, and is associated with miscarriage, preterm birth, and increased risk of acquiring other sexually transmitted infections, including HIV-1. Little is known of the daily changes in the vaginal bacterial composition as it progresses from treatment to recurrence, or whether any of these might be useful in its prediction or an understanding of its causes. We used phylogenetic branch-inclusive quantitative PCR (PB-qPCR) and Lactobacillus blocked/unblocked qPCR (Lb-qPCR) to characterize longitudinal changes in the vaginal microbiota in sequential vaginal self-swabs from five women with recurrent BV, from diagnosis through remission to recurrence. Both patients with acute BV samples dominated by G. vaginalis recurred during the study with similar profiles, whereas the three patients with acute BV samples dominated by other anaerobes did not recur or recurred to an intermediate Nugent score. L. iners dominated remission phases, with intermittent days of abnormal microbial profiles typically associated with menses. The exception was a newly discovered phenomenon, a sustained period of abnormal profiles, termed conversion, which preceded symptomatic acute BV. Species known to have antagonistic activity towards Lactobacillus were detected in pre-conversion samples, possibly contributing to the decline in Lactobacillus. Lb-qPCR scores define two categories of response in the initial post-treatment visit samples; scores <5 may correspond with poor response to treatment or rapid recurrence, whereas scores >8 may predict delayed or no recurrence. Amsel criteria or Nugent scores did not have this potential predictive capability. Larger studies are warranted to evaluate the prognostic potential of detecting conversion and poor Lb-qPCR scores at the post-treatment visit of recurrent BV patients. PMID:24376552

The aim of this study was to describe two of the outcomes of pregnancy, induced abortion and miscarriage, in three African countries. Major maternal risk factors were also evaluated. The study was prospective and based on the medical files of all 1,957 women admitted to participating health care structures. Overall, 988 women were admitted for complications of miscarriage, and 969 for complications of induced abortion. Gestational age was lower in women with miscarriages (p<0.002). The level of use of contraceptive methods ((p<0.003) and educational level ((p<0.005) were lower in women who had had an induced abortion. In our study, 26 maternal deaths were recorded, 22 of which were associated with induced abortion. Infection was the most important risk factor for death (OR=4.8; 1.9-12.4). Maternal deaths related to abortion complications often occurred shortly after hospital admission and with signs of sepsis. This demonstrates the importance of effective emergency services. Unfortunately, hospital-based studies alone cannot assess all maternal death risk factors, especially those for maternal death related to induced abortion complications. It is therefore important to determine what happened to the woman before hospital admission and during her stay in hospital. Combinations of qualitative and quantitative methods could be used to increase our understanding of this problem and to help us to solve it.

Idiopathic granulomatous mastitis is a rare chronic inflammatory lesion of the breast that can clinically and radiographically mimic breast carcinoma. The most common clinical presentation is an unilateral, discrete breast mass, nipple retraction and even a sinus formation often associated with an inflammation of the overlying skin. The etiology of idiopathic granulomatous mastitis is still obscure. Its treatment remains controversial. The cause may be the autoimmune process, infection, a chemical reaction associated with oral contraceptive pills, or even lactation. Various factors, including hormonal imbalance, autoimmunity, unknown microbiological agents, smoking and α 1-antitrypsin deficiency have been suggested to play a role in disease aetiology. In this review, causing factors in the aetiology of idiopathic granulomatous mastitis are reviewed in detail.

We report a case of idiopathic elephantiasis of penis. A 41-year-old man was refered to our hospital with a painful penile swelling and severe miction pain. He had no particular past or familial history, and had never been to tropical or semitropical region. Physical examination showed a prominent swelling and flection of his penis. Magnetic resonance imaging revealed a significant thickening of the penile skin and subcutaneous tissue. Due to the difficulty of voiding, an urethral catheter was placed. The penile skin biopsy showed no malignancy. Under the diagnosis of penile elephantiasis, the resection of abnormal penile skin and penile plasty with the split skin graft from his thigh was performed. Histopathological findings showed nonspecific inflammation. The skin graft was successfully adapted. He could urinate smoothly without pain after the urethral catheter was removed. There has been no recurrence 6 months after the operation. He recovered normal micturition and sexual function.

The aim of this work was to evaluate the effects of extreme body mass index (BMI) on assisted reproductive treatment outcome and pregnancy outcome. This is a descriptive cohort study that evaluated 8,145 consecutive in-vitro fertilisation/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) cycles in which BMI were known, from July 1997 to June 2005 in an inner London major fertility clinic. The data were collected prospectively and analysed retrospectively on women undergoing IVF/ICSI and ET. Patients' weight and height were established prior to treatment. IVF/ICSI treatment was then started using either a long or an antagonist protocol. Patients were divided into five groups: Group A (BMI < 19); Group B (BMI between 19 and 25.9); Group C (BMI between 26 and 30.9); Group D (BMI between 31 and 35.9); Group E (BMI > 36). The main outcomes measured were number of eggs collected, fertilisation rate, number of embryos available for transfer, pregnancy rate (PR), live-birth rate (LBR) and miscarriage rate (MR). The results showed no significant difference in the average number of days taking follicle stimulating hormone (FSH) for ovarian stimulation, the average amount of gonadotrophin used for stimulation, number of eggs collected and fertilisation rate. The pregnancy rate, miscarriage rate and the live-birth rate were not statistically different between all groups. However, in group E the miscarriage rate was significantly higher and the LBR was statistically lower compared with group B. We concluded that extreme BMI did not affect the super-ovulation outcome fertilisation rate and pregnancy rate. Women with a BMI > 35 had a higher miscarriage rate and hence a lower live-birth rate, but a reasonable pregnancy and live-birth rate can be achieved. For women with a BMI < 20 there was no difference in assisted reproduction treatment (ART) outcome and pregnancy outcome when compared with women with a normal BMI. This information should be used to advise patients

Catheter ablation for idiopathic ventricular arrhythmia (VA) is effective and safe, but efficacy is frequently limited due to an epicardial origin and difficult anatomy. The remote magnetic navigation (RMN) catheter has a flexible catheter design allowing access to difficult anatomy. We describe the efficacy of the RMN for ablation of idiopathic VA after failed manual ablation. Among 235 patients with idiopathic VA referred for catheter ablation, we identified 51 patients who were referred for repeat ablation after a failed manual ablation. We analyzed the clinical characteristics, including the successful ablation site and findings at electrophysiology study, in repeat procedures conducted using RMN as compared with manual ablation. Among these patients, 22 (43 %) underwent repeat ablation with the RMN and 29 (57 %) underwent repeat ablation with a manual ablation. Overall, successful ablation rate was significantly higher using RMN as compared with manual ablation (91 vs. 69 %, P = 0.02). Fluoroscopy time in the RMN was 17 ± 12 min as compared with 43 ± 18 min in the manual ablation (P = 0.009). Successful ablation rate in the posterior right ventricular outflow tract (RVOT) plus posterior-tricuspid annulus was higher with RMN as compared with manual ablation (92 vs. 50 %, P = 0.03). Neither groups exhibited any major complications. The RMN is more effective in selected patients with recurrent idiopathic VA after failed manual ablation and is associated with less fluoroscopy time. The RMN catheters have a flexible design enabling them to access otherwise difficult anatomy including the posterior tricuspid annulus and posterior RVOT.

Initial Steroid Sensitivity in Children with Steroid-Resistant Nephrotic Syndrome Predicts Post-Transplant Recurrence

Of children with idiopathic nephrotic syndrome, 10%–20% fail to respond to steroids or develop secondary steroid resistance (termed initial steroid sensitivity) and the majority progress to transplantation. Although 30%–50% of these patients suffer disease recurrence after transplantation, with poor long-term outcome, no reliable indicator of recurrence has yet been identified. Notably, the incidence of recurrence after transplantation appears reduced in patients with steroid-resistant nephrotic syndrome (SRNS) due to monogenic disorders. We reviewed 150 transplanted patients with SRNS to identify biomarkers that consistently predict outcome of SRNS after transplantation. In all, 25 children had genetic or familial SRNS and did not experience post-transplant recurrence. We reviewed phenotypic factors, including initial steroid sensitivity, donor type, age, ethnicity, time to ESRD, and time on dialysis, in the remaining 125 children. Of these patients, 57 (45.6%) developed post-transplant recurrence; 26 of 28 (92.9%) patients with initial steroid sensitivity recurred after transplantation, whereas only 26 of 86 (30.2%) patients resistant from the outset recurred (odds ratio, 30; 95% confidence interval, 6.62 to 135.86; P<0.001). We were unable to determine recurrence in two patients (one with initial steroid sensitivity), and nine patients did not receive initial steroids. Our data show that initial steroid sensitivity is highly predictive of post-transplant disease recurrence in this pediatric patient population. Because a pathogenic circulating permeability factor in nephrotic syndrome remains to be confirmed, we propose initial steroid sensitivity as a surrogate marker for post-transplant recurrence.

Idiopathic granulomatous mastitis: a medical or surgical disease of the breast?

PubMed

Skandarajah, Anita; Marley, Leah

2015-12-01

Idiopathic granulomatous mastitis (IGM) is a rare benign breast disease, which can be protracted, disfiguring and may be linked to an underlying autoimmune disorder. The clinical presentation may mimic bacterial mastitis or carcinoma. To review the mode of presentation, diagnosis, management, resolution and incidence of IGM in three tertiary breast centres and propose guidelines for management. The breast and anatomical databases of three centres were reviewed from January 2000 to December 2013 to identify patients with histological diagnosis of IGM. Clinical and demographic characteristics were retrieved and treatment modalities and time to resolution were recorded. Seventeen patients were identified with a median age of 40. The majority of patients were premenopausal, multiparous and presented with a mass. All patients had initial treatment as infectious mastitis. The diagnosis was made by core biopsy in 71%. Eleven patients required immunosuppressive treatment with steroids and four of these patients required a steroid-sparing agent because of steroidal side effects, recurrence or persistence of symptoms. The median time to resolution was 3 months (0-24 months). One patient had subsequent systemic Wegener's granulomatosis diagnosed. Idiopathic granulomatosis mastitis requires histological confirmation, close monitoring, exclusion of underlying systemic autoimmune conditions and judicious use of steroids and steroid-sparing agents such as methotrexate. It has a protracted course with some patients relapsing quickly upon cessation of steroids. © 2014 Royal Australasian College of Surgeons.

A 69 year old man was admitted for investigation of right sided pleuritic chest pain and dyspnoea, both of which began suddenly four days before admission. Acute pulmonary embolism was diagnosed. Six months after discharge while on warfarin he died. Necropsy found a 50 mm diameter myxoid tumour arising on the right atrial side of the interatrial septum. This lesion may have been discovered earlier by echocardiography although there were no clear indications for this investigation. Presentation was that of recurrent pulmonary embolism with no obvious source or cause of thrombosis. Patients who are thought to have idiopathic pulmonary embolism should undergo early echocardiography to exclude the rare but treatable diseases of the right heart that may be responsible

The Respiratory Support and Sleep Centre at Papworth Hospital, Cambridge, UK. A large database of more than 6000 patients with sleep disorders was reviewed. A retrospective study of the clinical and polysomnographic characteristics of 77 patients with idiopathic hypersomnia was performed. Comparison with a similar group of patients with narcolepsy was performed. The response to drug treatment was assessed in 61 patients over a mean follow-up of 3.8 years. Idiopathic hypersomnia was 60% as prevalent as narcolepsy. Comparison with a similar group of patients with narcolepsy showed that those with idiopathic hypersomnia were more likely to have prolonged unrefreshing daytime naps, a positive family history, increased slow-wave sleep, and a longer sleep latency on the Multiple Sleep Latency Test. The results of the Multiple Sleep Latency Test were not helpful in predicting disease severity or treatment response. The clinical features were heterogeneous and of variable severity. The majority of patients with idiopathic hypersomnia had symptoms that remained stable over many years, but 11% had spontaneous remission, which was never seen in narcolepsy. Two thirds of patients with idiopathic hypersomnolence had a sustained improvement in daytime somnolence with medication, although a third needed high doses or combinations of drugs. Idiopathic hypersomnolence has characteristic clinical and polysomnographic features but the prolonged latency on the Multiple Sleep Latency Test raises doubt about the validity of this test within the current diagnostic criteria. The disease often responds well to treatment and a substantial minority of patients appear to spontaneously improve.

Surgical versus expectant management in women with an incomplete evacuation of the uterus after treatment with misoprostol for miscarriage: the MisoREST trial

PubMed Central

2013-01-01

Background Medical treatment with misoprostol is a non-invasive and inexpensive treatment option in first trimester miscarriage. However, about 30% of women treated with misoprostol have incomplete evacuation of the uterus. Despite being relatively asymptomatic in most cases, this finding often leads to additional surgical treatment (curettage). A comparison of effectiveness and cost-effectiveness of surgical management versus expectant management is lacking in women with incomplete miscarriage after misoprostol. Methods/Design The proposed study is a multicentre randomized controlled trial that assesses the costs and effects of curettage versus expectant management in women with incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage. Eligible women will be randomized, after informed consent, within 24 hours after identification of incomplete evacuation of the uterus by ultrasound scanning. Women are randomly allocated to surgical or expectant management. Curettage is performed within three days after randomization. Primary outcome is the sonographic finding of an empty uterus (maximal diameter of any contents of the uterine cavity < 10 millimeters) six weeks after study entry. Secondary outcomes are patients’ quality of life, surgical outcome parameters, the type and number of re-interventions during the first three months and pregnancy rates and outcome 12 months after study entry. Discussion This trial will provide evidence for the (cost) effectiveness of surgical versus expectant management in women with incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage.

To present a recurrent case of conforming focal choroidal excavation (FCE) following multiple evanescent white dot syndrome (MEWDS) in a 25-year-old woman. Following spontaneous MEWDS sings resolution our patient noted a recurrent decrease in vision. Repeated OCT revealed elevation and mild disruption of RPE layer at fovea without previous angiographic MEWDS signs. At this time, short-term systemic steroid therapy was started and visual acuity became normal. Following quiescence of the new-onset phase, the conforming type of FCE located in inferior macula appeared in OCT. In the following next 2 years recurrence of presumptive focal subfoveal choriocapillaritis occurred for three times presenting with blurred vision. During every acute attack, above-mentioned FCE disappeared and returned back again after resolution of presumptive focal choriocapillaritis. This is the first and unique case of recurrent type of FCE following MEWDS. It seems to disappear during active phase of presumptive focal choriocapillaritis and then returns after the eye has become quiescent.

Amioradone-induced hyperthyroidism is a common complication of amiodarone therapy. Although definitive interruption of amiodarone is recommended because of the risks of aggravation of the arrhythmias, some patients may require the reintroduction of amiodarone several months after normalisation of thyroid function. The authors undertook a retrospective study of the effects of preventive treatment of recurrences of amiodarone-induced hyperthyroidism with I131. The indication of amiodarone therapy was recurrent, symptomatic, paroxysmal atrial fibrillation in 13 cases and ventricular tachycardia in 5 cases (M = 14, average age 64 +/- 13 years). The underlying cardiac disease was dilated cardiomyopathy (N = 5), ischaemic heart disease (N = 3), hypertensive heart disease (N = 2), arrhythmogenic right ventricular dysplasia (N = 2) or valvular heart disease (N = 2). Two patients had idiopathic atrial fibrillation. An average dose of 576 +/- 184 MBq of I131 was administered 34 +/- 37 months after an episode of amiodarone-induced hyperthyroidism. Amiodarone was reintroduced in 16 of the 18 patients after a treatment-free period of 98 +/- 262 days. Transient post-radioiodine hyperthyroidism was observed in 3 cases (17%). Sixteen patients (89%) developed hypothyroidism requiring replacement therapy with L-thyroxine. There were no recurrences of amiodarone-induced hyperthyroidism. After 24 +/- 17 months follow-up, the arrhythmias were controlled in 13 of the 16 patients (81%) who underwent the whole treatment sequence. The authors conclude that preventive treatment with I131 is an effective alternative to prevent recurrence of amiodarone-induced hyperthyroidism in patients requiring reintroduction of amiodarone to control their arrhythmias.

Idiopathic facial palsy is the most common cause of facial nerve palsy in children. Controversy exists regarding treatment options. The objectives of this study were to review the epidemiological and clinical characteristics as well as the outcome of idiopathic facial palsy in children to suggest appropriate treatment. A retrospective study was conducted on children with a diagnosis of idiopathic facial palsy from 2007 to 2012. A total of 37 cases (13 males, 24 females) with a mean age of 13.9 years were included in this analysis. The mean duration between onset of Bell's palsy and consultation was 3 days. Of these patients, 78.3% had moderately severe (grade IV) or severe paralysis (grade V on the House and Brackmann grading). Twenty-seven patients were treated in an outpatient context, three patients were hospitalized, and seven patients were treated as outpatients and subsequently hospitalized. All patients received corticosteroids. Eight of them also received antiviral treatment. The complete recovery rate was 94.6% (35/37). The duration of complete recovery was 7.4 weeks. Children with idiopathic facial palsy have a very good prognosis. The complete recovery rate exceeds 90%. However, controversy exists regarding treatment options. High-quality studies have been conducted on adult populations. Medical treatment based on corticosteroids alone or combined with antiviral treatment is certainly effective in improving facial function outcomes in adults. In children, the recommendation for prescription of steroids and antiviral drugs based on adult treatment appears to be justified. Randomized controlled trials in the pediatric population are recommended to define a strategy for management of idiopathic facial paralysis. Copyright © 2015 Elsevier Masson SAS.

Women experiencing miscarriage are offered a choice of different treatments to terminate their wanted pregnancy at a time when they are often shocked and distressed. Women's and healthcare professionals' experiences of the decision-making process are not well described. We aimed to gain insight into this process and the circumstances that may affect it. A qualitative study using a grounded theory approach. Data were obtained through semi-structured interviews with six women who had chosen and completed either surgical, medical or expectant treatment for miscarriage and five healthcare professionals involved in the decision-making at an emergency gynaecological department in Denmark. An inductive explorative method was chosen due to limited knowledge about the decision-making process, and a theoretical perspective was not applied until the final analysis. Despite information and pretreatment counselling, choice of treatment was often determined by unspoken emotional considerations, including fear of seeing the foetus or fear of anaesthesia. These considerations were not discussed during the decision-making process, which was a time when the women were under time pressure and experienced emotional distress. Healthcare professionals did not explore women's considerations for choosing a particular treatment and prioritised information differently. We found theory about coping and decision-making in stressful situations useful in increasing our understanding of the women's reactions. In relation to theory about informed consent, our findings suggest that women need more understanding of the treatments before making a decision. This study is limited due to a small sample size, but it generates important findings that need to be examined in a larger sample. Frequently, women did not use information provided about treatment pros and cons in their decision-making process. Because of unspoken thoughts, and women's needs being unexplored by healthcare professionals

Should idiopathic facial aseptic granuloma be considered granulomatous rosacea? Report of three pediatric cases.

2013-01-01

Idiopathic facial aseptic granuloma (IFAG), or pyodermite froide du visage, is a skin disease reported only in children and characterized by painless red nodules usually located on the cheeks. Its etiology is still unclear, but some authors considered the possibility that IFAG might be included in the spectrum of granulomatous rosacea (GR). The histopathological features of IFAG and GR are quite similar, showing perifolliculitis, granulomas, folliculitis, and lymphocytes and plasmacells around epithelioid histiocytes. In the present article, we discuss three cases in which an association between a facial nodule, compatible with both IFAG and GR, and recurrent chalazia make us support the hypothesis that IFAG should be considered as GR. © 2012 Wiley Periodicals, Inc.

Immunology and human reproduction.

2015-06-01

The immune system's role in recurrent reproductive failure is a controversial issue in assisted reproduction. New insight about maternal tolerance in assisted reproduction has been reported and could explain some of the recurrent miscarriage and/or recurrent implantation failure related causes named until now as unknown. Most of the previous studies about immune system implication in reproduction were focused on finding markers on peripheral blood. Maternal tolerance begins at the uterine level, so successful adaptation to the fetus happens after a complicated process. Insufficient invasion of the uterine lining by invading extravillous trophoblast is the primary defect in pregnancy disorders such as recurrent miscarriage, and this process is regulated by interaction between maternal killer immunoglobulin-like receptors (KIRs) expressed by the uterine natural killer cells and their ligand human leukocyte antigen (HLA)-C expressed by extravillous trophoblast. Pregnancies are an increased risk of disorders in mothers with KIR AA when the fetus has paternal HLA-C2. Recently, it has been reported that the expression of more than one paternal HLA-C by extravillous trophoblast in assisted reproduction may affect placentation in mothers with KIR AA. The review provides insight about the immune tolerance process. These insights could have an impact on the selection of single embryo transfer and/or oocyte/sperm donor according to HLA-C in patients with recurrent miscarriage or recurrent implantation failure and a KIR AA haplotype.

Chronic recurrent multifocal osteomyelitis is an idiopathic nonpyogenic autoinflammatory bone disorder involving multiple sites, with clinical progression persisting for more than 6 months and which may have episodes of remission and exacerbation in the long term. It represents up to 2-5% of the cases of osteomyelitis, with an approximate incidence of up to 4/1,000,000 individuals, and average age of disease onset estimated between 8-11 years, predominantly in females. The legs are the most affected, with a predilection for metaphyseal regions along the growth plate. We describe the case of a female patient, aged 2 years and 5 months, with involvement of the left ulna, right jaw and left tibia, showing a predominance of periosteal reaction as main finding.

Background Strenuous occupational physical activity and physical demands may be risk factors for adverse reproductive outcomes. Methods A retrospective study in the Shanghai, China textile industry study collected women’s self-reported reproductive history. Occupational physical activity assessment linked complete work history data to an industry-specific job-exposure matrix. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by multivariate logistic regression for the first pregnancy outcome and utilized generalized estimating equations to consider all pregnancies per woman. Results Compared with women employed in sedentary jobs, a reduced risk of miscarriage was found for women working in jobs with either light (OR 0.18, 95%CI: 0.07, 0.50) or medium (OR 0.24, 95%CI: 0.08, 0.66) physical activity during the first pregnancy and over all pregnancies (light OR 0.32, 95%CI: 0.17, 0.61; medium OR 0.43, 95%CI: 0.23, 0.80). Frequent crouching was associated with elevated risk (OR 1.82, 95%CI: 1.14, 2.93; all pregnancies per woman). Conclusions Light/medium occupational physical activity may have reduced miscarriage risk, while specific occupational characteristics such as crouching may have increased risk in this cohort.

This review summarizes the evidence concerning effects of night shift work on women's reproductive health, specifically difficulty in conceiving and miscarriage. We distinguish between fixed night shift and rotating night shift, as the population subgroups exposed, the social and biological mechanisms, and the magnitude of effects are likely to differ; of note, women working fixed night shift are known to have high tolerance for this schedule. We identified two relevant systematic reviews with meta-analyses and five additional studies. Night shift work may give rise to menstrual cycle disturbances, but effect sizes are imprecise. Endometriosis may be elevated in night shift workers, but evidence is only preliminary. Adequate data are lacking to assess associations between night shift work and infertility or time to pregnancy. The weight of evidence begins to point to working at night, whether in fixed or rotating shifts, as a risk factor for miscarriage. There are many methodological problems with this literature, with substantial variation in the definitions of night shift and schedule types making comparisons between studies difficult and pooling across studies questionable. Nevertheless, there appears to be grounds for caution and counselling where women have concerns about night shift work and their reproductive health.

2008-01-01

Introduction Patients with severe idiopathic scoliosis are reported to have significant pulmonary complications, including recurrent chest infections, alveolar hypoventilation and respiratory failure. Case presentation We report a case of a 13-year-old boy with moderate-to-severe scoliosis resulting in torsion or twisting of the bronchus intermedius, which contributed to airflow obstruction defects, as revealed by both spirometry and bronchoscopy. Conclusion We recommend that inspection of the shape of the maximal expiratory flow-volume loop obtained from spirometry, as well as other parameters suggestive of obstructive lung disease, may be important in children with scoliosis. To the best of the authors' knowledge, this is the first report of a child in which pulmonary function testing and direct visualization via a flexible bronchoscope have been used to characterize intrathoracic large airway obstruction.

This is a pilot study to investigate the type and severity of emotional distress in women after early pregnancy loss (EPL), compared with a control group with ongoing pregnancies. The secondary aim was to assess whether miscarriage or ectopic pregnancy impacted differently on the type and severity of psychological morbidity. This was a prospective survey study. Consecutive women were recruited between January 2012 and July 2013. We emailed women a link to a survey 1, 3 and 9 months after a diagnosis of EPL, and 1 month after the diagnosis of a viable ongoing pregnancy. The Early Pregnancy Assessment Unit (EPAU) of a central London teaching hospital. We recruited 186 women. 128 had a diagnosis of EPL, and 58 of ongoing pregnancies. 11 withdrew consent, and 11 provided an illegible or invalid email address. Post-traumatic stress disorder (PTSD) was measured using the Post-traumatic Diagnostic Scale (PDS), and anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). Response rates were 69/114 at 1 month and 44/68 at 3 months in the EPL group, and 20/50 in controls. Psychological morbidity was higher in the EPL group with 28% meeting the criteria for probable PTSD, 32% for anxiety and 16% for depression at 1 month and 38%, 20% and 5%, respectively, at 3 months. In the control group, no women met criteria for PTSD and 10% met criteria for anxiety and depression. There was little difference in type or severity of distress following ectopic pregnancy or miscarriage. We have shown a large number of women having experienced a miscarriage or ectopic pregnancy fulfil the diagnostic criteria for probable PTSD. Many suffer from moderate-to-severe anxiety, and a lesser number depression. Psychological morbidity, and in particular PTSD symptoms, persists at least 3 months following pregnancy loss.

In the United Kingdom, lower incidences of intraspinal abnormalities in patients with early onset idiopathic scoliosis have been observed than in studies in other countries. We aimed to determine the rates of these abnormalities in United Kingdom patients diagnosed with idiopathic scoliosis before the age of 11 years. This retrospective study of patients attending an urban scoliosis clinic identified 71 patients satisfying a criteria of: clinical diagnosis of idiopathic scoliosis; age of onset ten years and 11 months or less; MRI screening for intraspinal abnormalities. United Kingdom census data combined with patient referral data was used to calculate incidence. Mean age at diagnosis was six years with 39 right-sided and 32 left-sided curves. Four patients (5.6%) were found to have intraspinal abnormalities on MRI. These consisted of: two combined Arnold-Chiari type 1 malformations with syrinx; one syrinx with a low lying conus; and one isolated syrinx. Overall annual incidence of early onset idiopathic scoliosis was one out of 182 000 (0.0006%). This study reports the lowest rates to date of intraspinal anomalies in patients with early onset idiopathic scoliosis, adding to knowledge regarding current incidences of these abnormalities as well as any geographical variation in the nature of the disease.

We evaluated factors associated with pathogenic genetic variants in patients with idiopathic pancreatitis. Genetic testing (PRSS1, CFTR, SPINK1, and CTRC) was performed in all eligible patients with idiopathic pancreatitis between 2010 to 2015. Patients were classified into the following groups based on a review of medical records: (1) acute recurrent idiopathic pancreatitis (ARIP) with or without underlying chronic pancreatitis; (2) idiopathic chronic pancreatitis (ICP) without a history of ARP; (3) an unexplained first episode of acute pancreatitis (AP)<35 years of age; and (4) family history of pancreatitis. Logistic regression analysis was used to determine the factors associated with pathogenic genetic variants. Among 197 ARIP and/or ICP patients evaluated from 2010 to 2015, 134 underwent genetic testing. A total of 88 pathogenic genetic variants were found in 64 (47.8%) patients. Pathogenic genetic variants were identified in 58, 63, and 27% of patients with ARIP, an unexplained first episode of AP <35 years of age, and ICP without ARP, respectively. ARIP (OR: 18.12; 95% CI: 2.16-151.87; P=0.008) and an unexplained first episode of AP<35 years of age (OR: 2.46; 95% CI: 1.18-5.15; P=0.017), but not ICP, were independently associated with pathogenic genetic variants in the adjusted analysis. Pathogenic genetic variants are most likely to be identified in patients with ARIP and an unexplained first episode of AP<35 years of age. Genetic testing in these patient populations may delineate an etiology and prevent unnecessary diagnostic testing and procedures.

Background Recurrent miscarriage, also referred to as recurrent spontaneous abortion (RSA), affects 1 – 5% of couples and has a multifactorial genesis. Acquired and congenital thrombophilia have been discussed as hemostatic risk factors in the pathogenesis of RSA. Method This review article was based on a selective search of the literature in PubMed. There was a special focus on the current body of evidence studying the association between RSA and antiphospholipid syndrome and hereditary thrombophilia disorders. Results Antiphospholipid syndrome (APS) is an acquired autoimmune thrombophilia and recurrent miscarriage is one of its clinical classification criteria. The presence of lupus anticoagulant has been shown to be the most important serologic risk factor for developing complications of pregnancy. A combination of low-dose acetylsalicylic acid and heparin has shown significant benefits with regard to pregnancy outcomes and APS-related miscarriage. Some congenital thrombophilic disorders also have an increased associated risk of developing RSA, although the risk is lower than for APS. The current analysis does not sufficiently support the analogous administration of heparin as prophylaxis against miscarriage in women with congenital thrombophilia in the same way as it is used in antiphospholipid syndrome. The data on rare, combined or homozygous thrombophilias and their impact on RSA are still insufficient. Conclusion In contrast to antiphospholipid syndrome, the current data from studies on recurrent spontaneous abortion do not support the prophylactic administration of heparin to treat women with maternal hereditary thrombophilia in subsequent pregnancies. Nevertheless, the maternal risk of thromboembolic events must determine the indication for thrombosis prophylaxis in pregnancy. PMID:29576632

CSF volumes in the basal cistern and Sylvian fissure are increased in both idiopathic normal pressure hydrocephalus and Alzheimer disease, though the differences in these volumes in idiopathic normal pressure hydrocephalus and Alzheimer disease have not been well-described. Using CSF segmentation and volume quantification, we compared the distribution of CSF in idiopathic normal pressure hydrocephalus and Alzheimer disease. CSF volumes were extracted from T2-weighted 3D spin-echo sequences on 3T MR imaging and quantified semi-automatically. We compared the volumes and ratios of the ventricles and subarachnoid spaces after classification in 30 patients diagnosed with idiopathic normal pressure hydrocephalus, 10 with concurrent idiopathic normal pressure hydrocephalus and Alzheimer disease, 18 with Alzheimer disease, and 26 control subjects 60 years of age or older. Brain to ventricle ratios at the anterior and posterior commissure levels and 3D volumetric convexity cistern to ventricle ratios were useful indices for the differential diagnosis of idiopathic normal pressure hydrocephalus or idiopathic normal pressure hydrocephalus with Alzheimer disease from Alzheimer disease, similar to the z-Evans index and callosal angle. The most distinctive characteristics of the CSF distribution in idiopathic normal pressure hydrocephalus were small convexity subarachnoid spaces and the large volume of the basal cistern and Sylvian fissure. The distribution of the subarachnoid spaces in the idiopathic normal pressure hydrocephalus with Alzheimer disease group was the most deformed among these 3 groups, though the mean ventricular volume of the idiopathic normal pressure hydrocephalus with Alzheimer disease group was intermediate between that of the idiopathic normal pressure hydrocephalus and Alzheimer disease groups. The z-axial expansion of the lateral ventricle and compression of the brain just above the ventricle were the common findings in the parameters for differentiating

When there's a heartbeat: miscarriage management in Catholic-owned hospitals.

PubMed

Freedman, Lori R; Landy, Uta; Steinauer, Jody

2008-10-01

As Catholic-owned hospitals merge with or take over other facilities, they impose restrictions on reproductive health services, including abortion and contraceptive services. Our interviews with US obstetrician-gynecologists working in Catholic-owned hospitals revealed that they are also restricted in managing miscarriages. Catholic-owned hospital ethics committees denied approval of uterine evacuation while fetal heart tones were still present, forcing physicians to delay care or transport miscarrying patients to non-Catholic-owned facilities. Some physicians intentionally violated protocol because they felt patient safety was compromised. Although Catholic doctrine officially deems abortion permissible to preserve the life of the woman, Catholic-owned hospital ethics committees differ in their interpretation of how much health risk constitutes a threat to a woman's life and therefore how much risk must be present before they approve the intervention.

Clinical Immunology Review Series: An approach to the patient with recurrent orogenital ulceration, including Behçet's syndrome

PubMed Central

Keogan, M T

2009-01-01

Patients presenting with recurrent orogenital ulcers may have complex aphthosis, Behçet's disease, secondary complex aphthosis (e.g. Reiter's syndrome, Crohn's disease, cyclical neutropenia) or non-aphthous disease (including bullous disorders, erythema multiforme, erosive lichen planus). Behçet's syndrome is a multi-system vasculitis of unknown aetiology for which there is no diagnostic test. Diagnosis is based on agreed clinical criteria that require recurrent oral ulcers and two of the following: recurrent genital ulcers, ocular inflammation, defined skin lesions and pathergy. The condition can present with a variety of symptoms, hence a high index of suspicion is necessary. The most common presentation is with recurrent mouth ulcers, often with genital ulcers; however, it may take some years before diagnostic criteria are met. All patients with idiopathic orogenital ulcers should be kept under review, with periodic focused assessment to detect evolution into Behçet's disease. There is often a delay of several years between patients fulfilling diagnostic criteria and a diagnosis being made, which may contribute to the morbidity of this condition. Despite considerable research effort, the aetiology and pathogenesis of this condition remains enigmatic. PMID:19210521

2003-03-22

Abnormal vaginal flora and bacterial vaginosis are associated with amplified risks of late miscarriage and spontaneous preterm delivery. We aimed to establish whether antibiotic treatment early in the second trimester might reduce these risks in a general obstetric population. We screened 6120 pregnant women attending hospital for their first antenatal visit--who were at 12-22 weeks' gestation (mean 15.6 weeks)--for bacterial vaginosis or abnormal vaginal flora. We used gram-stained slides of vaginal smears to diagnose abnormal vaginal flora or bacterial vaginosis, in accordance with Nugent's criteria. We randomly allocated 494 women with one of these signs to receive either clindamycin 300 mg or placebo orally twice daily for 5 days. Primary endpoints were spontaneous preterm delivery (birth > or =24 but <37 weeks) and late miscarriage (pregnancy loss > or =13 but <24 weeks). Analysis was intention to treat. Nine women were lost to follow-up or had elective termination. Thus, we analysed 485 women with complete outcome data. Women receiving clindamycin had significantly fewer miscarriages or preterm deliveries (13/244) than did those in the placebo group (38/241; percentage difference 10.4%, 95% CI 5.0-15.8, p=0.0003). Clindamycin also reduced adverse outcomes across the range of abnormal Nugent scores, with maximum effect in women with the highest Nugent score of 10. Treatment of asymptomatic abnormal vaginal flora and bacterial vaginosis with oral clindamycin early in the second trimester significantly reduces the rate of late miscarriage and spontaneous preterm birth in a general obstetric population.

Patients with portal hypertension without a demonstrable cause have been reported in the literature under several different terms, such as tropical splenomegaly, phlebosclerosis, obliterative portal venopathy of the liver, hepatoportal sclerosis, noncirrhotic portal fibrosis and idiopathic portal hypertension (IPH). Such patients have been described worldwide, with a greater frequency in India and Japan. The etiology of IPH is still unknown, although some of the theories that have been proposed are: exposure to toxic substances or drugs, relationship with the hepatitis-B virus, immunologic abnormalities, systemic or intra-abdominal infections and clotting abnormalities. The main histopathologic findings are periportal fibrosis, obliteration of small portal veins and sclerosis of the interhepatic portal system. Although these abnormalities could be secondary to portal hypertension, it has been proposed that the vascular changes are the primary event that leads to portal hypertension. The site of increased resistance in IPH is found at the presinusoidal level with some component at the sinusoidal and postsinusoidal level. The main symptoms and signs in IPH are upper gastrointestinal tract bleeding secondary to esophago-gastric varices, symptoms related to anemia, and splenomegaly. The long-term prognosis for patients with IPH is better than for cirrhotic patients, with a 77% survival at ten years. Variceal bleeding is the main cause of death, and some treatment to prevent bleeding or its recurrence is warranted. Although no comparative trial has been performed in IPH patients, the surgical management could be the first choice for elective treatment in these patient without liver failure, because of the high re-bleeding rates with chronic sclerotherapy. Pharmacologic management could be considered for prophylactic treatment of these patients.

Nonsurgical Management of Adolescent Idiopathic Scoliosis.

Pediatric patient visits for spinal deformity are common. Most of these visits are for nonsurgical management of scoliosis, with approximately 600,000 visits for adolescent idiopathic scoliosis (AIS) annually. Appropriate management of scoliotic curves that do not meet surgical indication parameters is essential. Renewed enthusiasm for nonsurgical management of AIS (eg, bracing, physical therapy) exists in part because of the results of the Bracing in Adolescent Idiopathic Scoliosis Trial, which is the only randomized controlled trial available on the use of bracing for AIS. Bracing is appropriate for idiopathic curves between 20° and 40°, with successful control of these curves reported in >70% of patients. Patient adherence to the prescribed duration of wear is essential to maximize the effectiveness of the brace. The choice of brace type must be individualized according to the deformity and the patient's personality as well as the practice setting and brace availability.

Immunosuppressive therapy has been-until the recent release of new guidelines on diagnosis and management-the recommended treatment for idiopathic pulmonary fibrosis. However, its efficacy in patients with idiopathic pulmonary fibrosis has always been a matter of debate. We report the occurrence of idiopathic pulmonary fibrosis in a white man receiving chronic immunosuppressive treatment following a heart transplant. This case report suggests that the immune mechanisms targeted by azathioprine and cyclosporine do not play a role in the pathogenesis of idiopathic pulmonary fibrosis.

Recurrent seizures, mental retardation and extensive brain calcinosis related to delayed diagnosis of hypoparathyroidism in an adolescent boy.

Reports of adolescent patients presenting with intractable seizures and mental retardation secondary to idiopathic hypothyroidism are uncommon in the literature. In this case, we report a 17-year-old boy who developed recurrent seizures, mental retardation and extensive brain calcinosis related to delayed diagnosis of hypoparathyroidism. Hypoparathyroidism can be easily missed in children and adolescents, and may lead to irreversible neurologic sequelae. This case highlights the need to consider hypocalcemia in any patient with uncontrolled seizures. Copyright © 2015 Elsevier Ltd. All rights reserved.

Refractory recurrent pericarditis is a major clinical challenge after colchicine failure, especially in corticosteroid-dependent patients. Human intravenous immunoglobulins (IVIGs) have been proposed as possible therapeutic options for these cases. The goal of this systematic review is to assess the efficacy and safety of IVIGs in this context. Studies reporting the use of IVIG for the treatment of recurrent pericarditis and published up to October 2014 were searched in several databases. All references found, upon initial assessment at title and abstract level for suitability, were consequently retrieved as full reports for further appraisal. Among the 18 citations retrieved, 17 reports (4 case series and 13 single case reports, with an overall population of 30 patients) were included. The mean disease duration was 14 months and the mean number of recurrences before IVIG was 3. Approximately 47% of patients had idiopathic recurrent pericarditis, 10% had an infective cause, and the remainder a systemic inflammatory disease. Nineteen out of the 30 patients (63.3%) were on corticosteroids at IVIG commencement. IVIGs were generally administered at a dose of 400-500 mg/kg/day for 5 consecutive days with repeated cycles according to the clinical response. Complications were uncommon (headache in ~3%) and not life-threatening. After a mean follow-up of approximately 33th months, recurrences occurred in 26.6% of cases after the first IVIG cycle, and 22 of the 30 patients (73.3%) were recurrence-free. Five patients (16.6%) were on corticosteroids at the end of the follow-up. IVIGs are rapidly acting, well tolerated, and efficacious steroid-sparing agents in refractory pericarditis.

A close association between narcolepsy and the Human Leukocyte Antigen (HLA)-DQB1*0602 allele suggests the involvement of the immune system, or possibly an autoimmune process. We investigated serum IgG levels in narcolepsy. We measured the serum total IgG levels in 159 Japanese narcolepsy-cataplexy patients positive for the HLA-DQB1*0602 allele, 28 idiopathic hypersomnia patients with long sleep time, and 123 healthy controls (the HLA-DQB1*0602 allele present in 45 subjects). The serum levels of each IgG subclass were subsequently measured. The distribution of serum IgG was significantly different among healthy controls negative for the HLA-DQB1*0602 allele (11.66+/-3.55 mg/ml), healthy controls positive for the HLA-DQB1*0602 allele (11.45+/-3.43), narcolepsy patients (9.67+/-3.38), and idiopathic hypersomnia patients (13.81+/-3.80). None of the following clinical variables, age, disease duration, Epworth Sleepiness Scale, smoking habit and BMI at the time of blood sampling, were associated with IgG levels in narcolepsy or idiopathic hypersomnia. Furthermore we found the decrease in IgG1 and IgG2 levels, stable expression of IgG3, and the increase in the proportion of IgG4 in narcolepsy patients with abnormally low IgG levels. The increase in the proportion of IgG4 levels was also found in narcolepsy patients with normal serum total IgG levels. Idiopathic hypersomnia patients showed a different pattern of IgG subclass distribution with high IgG3 and IgG4 level, low IgG2 level, and IgG1/IgG2 imbalance. Our study is the first to determine IgG abnormalities in narcolepsy and idiopathic hypersomnia by measuring the serum IgG levels in a large number of hypersomnia patients. The observed IgG abnormalities indicate humoral immune alterations in narcolepsy and idiopathic hypersomnia. Different IgG profiles suggest immunological differences between narcolepsy and idiopathic hypersomnia.

Pathology of idiopathic non-cirrhotic portal hypertension.

Idiopathic non-cirrhotic portal hypertension is an under-recognized vascular liver disease of unknown etiology, characterized by clinical signs of portal hypertension in the absence of cirrhosis. By definition, any disorder known to cause portal hypertension in the absence of cirrhosis and any cause of chronic liver disease must be excluded to make a diagnosis of idiopathic non-cirrhotic portal hypertension. However, the diagnosis is often difficult because the disease resembles cirrhosis and there is no gold standard test. Liver biopsy is an essential tool: it is able to exclude cirrhosis and other causes of portal hypertension and it allows the identification of the characteristic lesions. Nonetheless, the histological diagnosis of idiopathic non-cirrhotic portal hypertension is not always straightforward, in particular by needle biopsy samples, because there is no pathognomonic lesion, but rather a variety of vascular changes which are unevenly distributed, very subtle, and not all necessarily identified in a single specimen. Pathologists should be able to recognize several patterns of injury, involving portal/periportal areas as well as parenchymal structures.The histological features of idiopathic non-cirrhotic portal hypertension are described in this review, focusing on their interpretation in needle biopsy specimens.

Adolescent idiopathic scoliosis is a 3D spinal deformity in frontal, sagittal and axial planes, with high relevance in the pediatric population especially in adolescents and females between 10 years of age and the end of growth spurt and skeletal maturity. The radiographic manifestation is a curve greater than 10° measured by Cobb method associated with vertebral rotation. "Idiopathic" diagnosis has to be done after neuroanatomical anomalies of the posterior cerebral fosa and spinal canal have been ruled out. The physical finding of a thoracic or lumbar hump is the clinical manifestation of vertebral rotation seen in a forward bending test (Adam's Test). It is recommended that all curves with a magnitude greater than 20° have to be controlled and treated by a spinal surgeon being observation, bracing and surgery the different treatment options based on the extent, progression of deformity and basically the clinical condition of the patient.

Idiopathic pulmonary fibrosis is a fibrosing interstitial pneumonia associated with the radiological and/or histological pattern of usual interstitial pneumonia. Its aetiology is unknown, but probably comprises the action of endogenous and exogenous micro-environmental factors in subjects with genetic predisposition. Its diagnosis is based on the presence of characteristic findings of high-resolution computed tomography scans and pulmonary biopsies in absence of interstitial lung diseases of other aetiologies. Its clinical evolution is variable, although the mean survival rate is 2-5 years as of its clinical presentation. Patients with idiopathic pulmonary fibrosis may present complications and comorbidities which modify the disease's clinical course and prognosis. In the mild-moderate disease, the treatment consists of the administration of anti-fibrotic drugs. In severe disease, the best therapeutic option is pulmonary transplantation. In this paper we review the diagnostic and therapeutic aspects of the disease. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

Idiopathic toe walking.

PubMed

Oetgen, Matthew E; Peden, Sean

2012-05-01

Toe walking is a bilateral gait abnormality in which a normal heel strike is absent and most weight bearing occurs through the forefoot. This abnormality may not be pathologic in patients aged <2 years, but it is a common reason for referral to an orthopaedic surgeon. Toe walking can be caused by several neurologic and developmental abnormalities and may be the first sign of a global developmental problem. Cases that lack a definitive etiology are categorized as idiopathic. A detailed history, with careful documentation of the developmental history, and a thorough physical examination are required in the child with a primary report of toe walking. Treatment is based on age and the severity of the abnormality. Management includes observation, stretching, casting, bracing, chemodenervation, and surgical lengthening of the gastrocnemius-soleus complex and/or Achilles tendon. An understanding of idiopathic toe walking as well as treatment options and their outcomes can help the physician individualize treatment to achieve optimal results.

Small laser spot versus standard laser spot photodynamic therapy for idiopathic choroidal neovascularization: a randomized controlled study.

Li, Xiao-xin; Tao, Yong

2012-12-01

Idiopathic choroidal neovascularization (ICNV) affects young patients and thus may have a significant impact on vision and life quality over a patient's lifespan. This study was designed to compare the visual outcome and retinal pigment epithelium (RPE) damage after photodynamic therapy (PDT) with small laser spot and PDT with standard laser spot for idiopathic choroidal neovascularization (ICNV). This was a randomized controlled study. Fifty-two patients with ICNV were enrolled and randomly divided into a study group (small laser spot PDT, n = 27) and a control group (standard laser spot PDT, n = 25). Best corrected visual acuity (BCVA), optic coherence tomography (OCT) and fluorescein angiography (FA) findings were the main measurements. The patients were followed up 1 week, 1, 3, 6, 9 months and 1 year after PDT. BCVA improvement was statistically significantly higher in the study group than the control group at 6-month ((25.53 ± 15.01) letters vs. (14.71 ± 11.66) letters, P = 0.025) and 9-month follow-ups ((27.53 ± 17.78) letters vs. (15.59 ± 12.21) letters, P = 0.039). At 3- and 6-month follow-ups, the quadrants of RPE damage between the two groups varied significantly (P < 0.001 and P = 0.023, respectively). In each follow-up, the number of cases with decreased or unchanged leakage of choroidal neovascularization by FA and reduced subretinal fluid by OCT did not vary significantly between the two groups. Ten cases (37.0%) in the study group and eight cases (32.0%) in the control group suffered from recurrent CNV (P = 0.703). Better visual improvements, less RPE damage, a similar recurrent rate of CNV and change of subretinal fluid were observed in the small laser spot PDT group than in the standard laser spot PDT group for ICNV.

To describe the clinical features of idiopathic foveomacular retinoschisis not in association with myopia, glaucoma, optic disk pit, or juvenile retinoschisis. Retrospective observational case series. Five eyes of five patients with idiopathic foveomacular retinoschisis were included. The patients were 2 men and 3 women (average age, 75.2 years; range, 71-78 years). The average spherical equivalent was +2.40 diopters (range, +0.88 to +5.75 diopters), and the average axial length was 22.0 mm (range, 21.1-23.1 mm). All patients had retinoschisis from the macula to the optic disk in the affected eye. No patients had retinoschisis in the fellow eye. The average best-corrected visual acuity was 20/44 (68 Early Treatment Diabetic Retinopathy Study letter score). Idiopathic foveomacular retinoschisis is not inherited or associated with myopia, vitreomacular traction syndrome, optic pit, or glaucoma but is associated with older age, unilaterality, hyperopia with short axial length, complete posterior vitreous detachment, and weak leakage from the optic disk on fluorescein angiography.

ABSTRACT Background: The Fukushima Pregnancy and Birth Survey was launched to monitor pregnant mothers’ health after the Great East Japan Earthquake and Fukushima Daiichi Nuclear Power Plant (NPP) accident. Several lines of investigations have indicated that a disaster impacts maternal mental health with childbirth. However, there is no research regarding mental health of mothers with fetal loss after a disaster. In this report, we focus on those women immediately after the Great East Japan Earthquake and Fukushima NPP accident and discuss their support needs. Materials and Methods: Data regarding 61 miscarriages, 5 abortions, and 22 stillbirths were analyzed among the women who were pregnant at the time of the accident in the present study. We used a two-item case-finding instrument for depression screening, and compared the childbirth group with the fetal loss groups. We also analyzed mothers’ opinions written as free-form text. Results: Among the three fetal loss groups, the proportion of positive depression screens was significantly higher in the miscarriage and stillbirth group than in the childbirth group. Mothers’ opinions were grouped into six categories, with pregnancy-related items being most common, especially in the miscarriage and stillbirth groups. Conclusion: A higher proportion of Fukushima mothers with fetal loss, especially those with miscarriage and stillbirth, had depressive symptoms compared to those who experienced childbirth. Health care providers need to pay close attention to this vulnerable group and respond to their concerns regarding the effects on their fertility. PMID:26063510

Idiopathic scoliosis is a three-dimensional deformity of the growing spine, affecting 2%–3% of adolescents. Although benign in the majority of patients, the natural course of the disease may result in significant disturbance of body morphology, reduced thoracic volume, impaired respiration, increased rates of back pain, and serious esthetic concerns. Risk of deterioration is highest during the pubertal growth spurt and increases the risk of pathologic spinal curvature, increasing angular value, trunk imbalance, and thoracic deformity. Early clinical detection of scoliosis relies on careful examination of trunk shape and is subject to screening programs in some regions. Treatment options are physiotherapy, corrective bracing, or surgery for mild, moderate, or severe scoliosis, respectively, with both the actual degree of deformity and prognosis being taken into account. Physiotherapy used in mild idiopathic scoliosis comprises general training of the trunk musculature and physical capacity, while specific physiotherapeutic techniques aim to address the spinal curvature itself, attempting to achieve self-correction with active trunk movements developed in a three-dimensional space by an instructed adolescent under visual and proprioceptive control. Moderate but progressive idiopathic scoliosis in skeletally immature adolescents can be successfully halted using a corrective brace which has to be worn full time for several months or until skeletal maturity, and is able to prevent more severe deformity and avoid the need for surgical treatment. Surgery is the treatment of choice for severe idiopathic scoliosis which is rapidly progressive, with early onset, late diagnosis, and neglected or failed conservative treatment. The psychologic impact of idiopathic scoliosis, a chronic disease occurring in the psychologically fragile period of adolescence, is important because of its body distorting character and the onerous treatment required, either conservative or surgical

Recurrent pregnancy loss (RPL) is defined by two or more failed pregnancies. The relation between RPL and inherited thrombophilia requires anticoagulant therapy during pregnancy. However the obstetric outcomes have not been well defined in these RPL patients diagnosed with inherited thrombophilia, who have been given anticoagulant therapy. To investigate the obstetric outcomes in pregnant women with RPL who are given low molecular weight heparin (LMWH) and low-dose aspirin due to diagnosis of inherited thrombophilia. A hundred and eight RPL women were diagnosed with inherited thrombophilia, and 98 women were diagnosed with unexplained RPL. The patients with inherited thrombophilia were given LMWH and low-dose aspirin. Unexplained RPL patients were not given any medicine. The obstetric outcomes of participants were noted. In thrombophilic group, the live-birth levels were significantly higher [90 (83%) vs 67 (68%) p < 0.05], and the miscarriage levels were significantly lower than that in the control group [14 (13%) vs 27 (28%) p < 0.01]. The number of patients with preeclampsia was significantly higher in the thrombophilic group [16 (15%) vs 6 (6%) p < 0.05]. The number of preterm births was significantly higher than that of the controls [25 (23%) vs 10 (10%) p < 0.05]. The median gestation age of delivery was 35 weeks for thrombophilic patients and 38 weeks for controls (p < 0.05). The RPL patients diagnosed with inherited thrombophilia and who were given LMWH with low-dose aspirin had higher live-birth rates and lower miscarriage rates than those in the unexplained RPL patients. Increased risk of preeclampsia is seen in RPL patients with inherited thrombophilia despite thrombophilia prophylaxis.

Scoliosis is a three-dimensional deformation of the spine with a lateral curvature or deviation greater than 10 degrees and associated with vertebral rotation. Many conservative treatments are available for adolescents with idiopathic scoliosis, but the evidence for their effectiveness is still questioned. The objective of this study was to define the effectiveness of braces and individual physiotherapy for the comprehensive treatment of idiopathic scoliosis in adolescents. A retrospective study of 57 children with idiopathic thoracic dextroscoliosis with the magnitude of the thoracic curve between 20 degrees-35 degrees, treated in Orthopedic and Physiatrist Clinic as well as National Ortho-prosthetic Center within University Clinical Center of Kosova in Prishtina, during the period of 2003-2006. Inclusion of kinesitherapy in the comprehensive management of idiopathic scoliosis varied in the improvement of the muscle strength (satisfied and moderate) in almost 80% of the children while the correction of the curve was small in approximately 42.1% of cases. For children with idiopathic scoliosis, who require braces, an exercise program helps chest mobility, muscle strength, proper breathing flexibility in the spine, correct posture and keeps muscles in tone so that the transition period after brace removal is easier.

Acute exacerbation (AE) is a severe and life-threatening complication of idiopathic pulmonary fibrosis (IPF). In 2016, the definition and diagnostic criteria for AE-IPF were updated by an international working group. The new definition includes any acute, clinically significant respiratory deterioration (both idiopathic and triggered events) characterized by evidence of new widespread alveolar abnormality in patients with IPF. There are no currently proven beneficial management strategies for idiopathic and triggered AE-IPF. This is the first report describing AE-IPF triggered by Aspergillus empyema, which was improved by a combination of corticosteroid, systemic antifungal therapy, local antifungal therapy, and additional pharmacological therapies. Future research may reveal optimal strategies for both idiopathic and triggered AE-IPF.

Two patients with sickle cell disease presented with headaches and visual disturbances, typical complaints of this disorder. However, prompt diagnosis of idiopathic intracranial hypertension and initiation of medical therapy lead to improved symptoms and restored vision. Ophthalmologists should consider sickle cell disease to be an independent risk factor for idiopathic intracranial hypertension when a patient is being assessed for visual disturbances. Although a rare condition, idiopathic intracranial hypertension has several key signs useful in establishing a diagnosis. It is critical to recognize the warning signs and symptoms to prevent devastating ophthalmologic complications. We report the first cases of idiopathic intracranial hypertension in patients with the novel Quebec-Chori beta-chain variant of sickle cell disease.

Idiopathic pulmonary fibrosis is defined as chronic fibrosing interstitial pneumonia limited to the lung, with poor prognosis. The incidence has been rising in recent years probably due to improved diagnostic methods and increased life expectancy. In 2013, the SEPAR guidelines for the diagnosis and treatment for idiopathic pulmonary fibrosis were published. Since then, clinical trials and meta-analyses have shown strong scientific evidence for the use of pirfenidone and nintedanib in the treatment of idiopathic pulmonary fibrosis. In 2015, the international consensus of 2011 was updated and new therapeutic recommendations were established, prompting us to update our recommendation for the medical treatment of idiopathic pulmonary fibrosis accordingly. Diagnostic aspects and non-pharmacological treatment will not be discussed as no relevant developments have emerged since the 2013 guidelines. Copyright © 2017 SEPAR.

The aim of this study was to estimate the incidence of recurrent pregnancy loss (RPL). The prevalence of RPL defined as three or more consecutive miscarriages before gestation week 22, is often stated to be 1%. To our knowledge no study has estimated the incidence of RPL, which might be more informative and clinically relevant than the prevalence. This retrospective register-based study was conducted from 2003 until 2012 in Sweden with data provided by the Swedish National Board of Health and Welfare. In all, 6852 women were registered with the diagnoses of RPL in the National Patient Register. The incidence of RPL is the number of new women receiving the RPL diagnosis per year in the numerator and population at risk in the denominator. For each year, from 2003 to 2012, the incidence was calculated in two different risk populations: [1] all women aged 18-42 years, and [2] all women registered as being pregnant (deliveries or miscarriages). The average incidence in the study period was 53 per 100 000 (0.05%) in women aged 18-42 years and 650 per 100 000 (0.65%) in women who had achieved pregnancy in the period. The incidence of RPL in the two risk populations increased by 74 and 58%, respectively, during the study period. This study suggests that the incidence of RPL increased during the 10-year period studied. Causes can only be speculated upon in this study design, but might be associated with environmental changes, as the increase was fairly rapid. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

To compare pregnancy outcomes of two consecutive pregnancies in a cohort of women with recurrent pregnancy loss (RPL), in order to determine the long-term prognosis of women with RPL managed in a dedicated RPL clinic. A retrospective cohort study including 262 patients with two or more consecutive pregnancy losses followed by two subsequent pregnancies--index pregnancy (IP) and post-index pregnancy (PIP). All patients were evaluated and treated in the RPL clinic in the Soroka University Medical Center. Comparing IP with PIP, no significant difference in perinatal outcome was observed. The perinatal outcome remained encouraging with approximately 73% birth rate (73.7% versus 72.5%; p=0.83). Only 11% of the women with RPL continued to experience pregnancy losses for two subsequent pregnancies. In a multivariate logistic regression analysis, number of miscarriages pre-Index was the only factor independently associated with birth in the PIP. There is no significant difference between IP and PIP regarding perinatal outcome. Appropriate management in the RPL clinic conferred a significant beneficial effect on long-term pregnancy outcome of a cohort of women with RPL.

Miscarriage is the most common complication in pregnancy. Considering the importance of the problem thrombophilia in pregnant women and its association with recurrent pregnancy loss (RPL), analysis of polymorphisms of genes involved in thrombophilia can be useful. We investigated the frequency and association between ten polymorphisms of seven thrombophilia genes and RPL in an Iranian population. This case-control study was conducted on 200 women with recurrent pregnancy loss and also on 200 women with at least one successful pregnancy as the control group. Using PCR-RFLP, DNA from samples were analyzed for carrying A5279G, A4070G, and FV Leiden of factor V; FXIII (Val34Leu); FII (A20210G); BF (-455 G⁄A); ITGB3 (1565T⁄C); 677C/T and 1298A/C of MTHFR; and PAI-1 (-675 I/D, 5G/4G) polymorphisms. The BF(-455 G⁄A), MTHFR (677 C⁄T, 1298A⁄ C), PAI-1 (-675 I/D,4G⁄ 5G), FV Leiden, FV (A5279G), FXIII (Val34Leu) polymorphisms, which had shown positive relation, and ITGB3 1565T⁄C were the polymorphisms with negative relation to RPL. But in this study it is indicated that there is no significant association between FII (A20210G) and FV (A4070G) polymorphism and RPL. All the data acquired from the RPL patients in this experiment illustrate the importance of screening thrombophilia. Nevertheless, more studies on large-scale populations may be needed to identify novel genetic variants.

Most studies into immune system implication in reproduction have focused on finding markers of peripheral blood and less on the uterine environment. Peripheral blood natural killer cells have become an "immune study core" for women with recurrent miscarriage or recurrent implantation failure, based on the mistaken notion that they cause reproductive failure by killing or "rejecting" the embryo. Maternal-fetal tolerance begins at the uterine level, so successful adaptation to the fetus occurs after a complicated process. Insufficient uterine lining invasion by an invading extravillous trophoblast is the primary defect in pregnancy disorders such as recurrent miscarriage. This process is regulated by the interaction between maternal killer immunoglobulin-like receptors (KIRs), expressed by uterine natural killer cells (uNK), and their ligand human leukocyte antigen (HLA) C, expressed by the extravillous trophoblast. Pregnancies are an increased risk of disorders in mothers with KIR AA when the fetus has paternal HLA-C2. A recent report has indicated that the expression of more than one paternal HLA-C by the extravillous trophoblast in assisted reproduction may affect placentation in mothers with KIR AA. This review provides insight into the immune system's role in assisted reproductive treatments. These insights can have an impact on the selection of single-embryo transfer and/or oocyte/sperm donor according to HLA-C in patients with recurrent implantation failure and recurrent miscarriage depending on their KIR haplotype.

Idiopathic hypersomnia is characterized by excessive daytime sleepiness, despite normal or long sleep time. Its pathophysiological mechanisms remain unclear. This pilot study aims at characterizing the neural correlates of idiopathic hypersomnia using single photon emission computed tomography. Thirteen participants with idiopathic hypersomnia and 16 healthy controls were scanned during resting wakefulness using a high-resolution single photon emission computed tomography scanner with 99mTc-ethyl cysteinate dimer to assess cerebral blood flow. The main analysis compared regional cerebral blood flow distribution between the two groups. Exploratory correlations between regional cerebral blood flow and clinical characteristics evaluated the functional correlates of those brain perfusion patterns. Significance was set at p < .05 after correction for multiple comparisons. Participants with idiopathic hypersomnia showed regional cerebral blood flow decreases in medial prefrontal cortex and posterior cingulate cortex and putamen, as well as increases in amygdala and temporo-occipital cortices. Lower regional cerebral blood flow in the medial prefrontal cortex was associated with higher daytime sleepiness. These preliminary findings suggest that idiopathic hypersomnia is characterized by functional alterations in brain areas involved in the modulation of vigilance states, which may contribute to the daytime symptoms of this condition. The distribution of regional cerebral blood flow changes was reminiscent of the patterns associated with normal non-rapid-eye-movement sleep, suggesting the possible presence of incomplete sleep-wake transitions. These abnormalities were strikingly distinct from those induced by acute sleep deprivation, suggesting that the patterns seen here might reflect a trait associated with idiopathic hypersomnia rather than a non-specific state of sleepiness. © Sleep Research Society 2017.

Objective: A recent American Academy of Sleep Medicine publication identified a need for research regarding idiopathic hypersomnia. We describe various clinical and polysomnographic features of patients with idiopathic hypersomnia, with an emphasis on response to pharmacotherapy. Methods: A retrospective review of our database initially identified 997 patients, utilizing “idiopathic hypersomnia,” “hypersomnia NOS,” and “primary hypersomnia” as keywords. The charts of eligible patients were examined in detail, and data were abstracted and analyzed. Response to treatment was graded utilizing an internally developed scale. Results: Eighty-five patients were ultimately identified (65% female). Median (interquartile range) ages of onset and diagnosis were 19.6 (15.5) and 33.7 (15.5), respectively. During a median follow-up duration of 2.4 (4.7) years, 65% of patients demonstrated a “complete response” to pharmacotherapy as assessed by the authors' grading schema. Methylphenidate was most commonly used as a first-line agent prior to December 1998, but subsequently, modafinil became the most common first drug. At the last recorded follow-up visit, 92% of patients were on monotherapy, with greater representation of methylphenidate versus modafinil (51% vs. 32%). Among these patients, methylphenidate produced a higher percentage of “complete” or “partial” responses than modafinil, although statistical significance was not reached (38/40 [ 95%] vs 22/25 [88%], respectively, p = 0.291). Conclusions: The majority of patients with idiopathic hypersomnia respond well to treatment. Methylphenidate is chosen more often than modafinil as final monotherapy in the treatment of idiopathic hypersomnia, despite the fact that it is less commonly used initially. Further prospective comparisons of medications should be explored. Citation: Ali M; Auger RR; Slocumb NL; Morgenthaler TI. Idiopathic hypersomnia: clinical features and response to treatment.

Idiopathic pulmonary fibrosis is a progressive interstitial lung disease with no current effective therapies. Treatment has focused on antifibrotic agents to stop proliferation of fibroblasts and collagen deposition in the lung. We present the first clinical trial data on the use of losartan, an antifibrotic agent, to treat idiopathic pulmonary fibrosis. The primary objective was to evaluate the effect of losartan on progression of idiopathic pulmonary fibrosis measured by the change in percentage of predicted forced vital capacity (%FVC) after 12 months. Secondary outcomes included the change in forced expiratory volume at 1 second, diffusing capacity of carbon monoxide, 6-minute walk test distance, and baseline/transition dyspnea index. Patients with idiopathic pulmonary fibrosis and a baseline %FVC of ≥50 % were treated with losartan 50 mg by mouth daily for 12 months. Pulmonary function testing, 6-minute walk, and breathlessness indices were measured every 3 months. Twenty participants with idiopathic pulmonary fibrosis were enrolled and 17 patients were evaluable for response. Twelve patients had a stable or improved %FVC at study month 12. Similar findings were observed in secondary end-point measures, including 58, 71, and 65 % of patients with stable or improved forced expiratory volume at 1 second, diffusing capacity for carbon monoxide, and 6-minute walk test distance, respectively. No treatment-related adverse events that resulted in early study discontinuation were reported. Losartan stabilized lung function in patients with idiopathic pulmonary fibrosis over 12 months. Losartan is a promising agent for the treatment of idiopathic pulmonary fibrosis and has a low toxicity profile.

Brain MRI findings in patients with idiopathic hypersomnia.

Proper diagnosis of idiopathic hypersomnia necessitates the exclusion of neurologic or medical causes of sleepiness that better explain the clinical syndrome. However, there are no formal guidelines regarding the use of neuroimaging to identify such secondary causes of symptoms. We sought to characterize brain MRI findings in a series of patients with idiopathic hypersomnia. We reviewed medical records on a consecutive series of 61 patients diagnosed with idiopathic hypersomnia to determine the frequency and results of brain magnetic resonance imaging (MRI). One-third of patients had undergone brain MRI, with focal neurologic signs or symptoms being the most common indication for neuroimaging. Although seven patients had an identifiable finding on neuroimaging (e.g., chronic microvascular ischemic changes), clinical management was changed as a result of imaging in only three cases. In all three, the imaging finding was predated by clear clinical abnormalities. Neuroimaging may be a complementary part of an idiopathic hypersomnia evaluation, but the decision to pursue imaging should be made on a case-by-case basis. Copyright © 2017 Elsevier B.V.

Chronic histiocytic intervillositis (CHI) is characterized by the presence of histiocytes within the intervillous space of the placenta. The pathogenesis is unclear but available evidence supports an alloimmune mechanism on the basis of the presence in maternal blood of HLA antibodies directed against paternal HLA antigens. CHI has a high risk of recurrence and of abnormal perinatal outcomes. Little is known about the effects of CHI on the developing fetus, in particular on the growth and development of the skeleton. We have studied a woman whose third pregnancy was terminated after ultrasonography showed severe intrauterine growth restriction, raising the possibility of a lethal skeletal dysplasia. Postmortem radiographs showed multiple fractures and other signs of osteogenesis imperfecta (OI). However, bone histology was not typical of OI and no abnormalities were identified by sequencing OI genes. The subsequent pregnancy was also severely growth restricted and was terminated. The placenta showed chronic histiocytic intervillositis, which, on retrospective review, had also been present in her second and third pregnancies. Her fifth pregnancy was again associated with intrauterine growth restriction and CHI but resulted in a premature birth. CHI can be associated with radiographic features that mimic OI and should be considered when fetal fractures occur in the context of recurrent miscarriage, fetal death in utero, and intrauterine growth restriction. The correct diagnosis can be made by histopathology of the placenta, supported by bone histology and normal results of molecular studies for OI. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Idiopathic granulomatous mastitis is a chronic inflammatory disease of the breast, which is often difficult to differentiate both clinically and radiologically from infectious aetiologies such as tuberculosis, fungal infections, and also from malignancy, thus posing a diagnostic dilemma. We present a pictorial review of the commonly encountered imaging findings in idiopathic granulomatous mastitis on mammography and ultrasound. Mammographic and ultrasound findings of histopathologically proven cases of granulomatous mastitis are discussed. Idiopathic granulomatous mastitis has varied and non-specific appearances on ultrasound and mammography. Histopathology is essential to establish diagnosis. • Idiopathic granulomatous mastitis often poses a diagnostic dilemma for the radiologist by mimicking malignancy. • It has varied and non-specific appearances on mammography and ultrasound. • Histopathology is mandatory to establish the diagnosis and decide management.

Surgical intervention that improves pancreatic ductal drainage is a reasonable treatment strategy for recurrent pancreatitis in children. This study was approved by the Committee on Human Research (San Francisco, CA). A retrospective chart review was performed on children aged 0 to 17 years given the International Classification of Diseases, Ninth Revision coding diagnosis of chronic pancreatitis who underwent surgical intervention from 1981 to 2005. From 1981 to 2005, 32 children were treated for the diagnosis of chronic pancreatitis. The etiologies were obstructive (n = 13), idiopathic (n = 10), hereditary (n = 6), medications (n = 2), and infection (n = 1). Fifteen patients underwent 17 operations for chronic pancreatitis, including Puestow (n = 9), cystenterostomy (n = 2), Whipple (n = 1), distal pancreatectomy (n = 1), Frey (n = 1), DuVal (n = 1), excision of enteric duplication cyst (n = 1), and pancreatic ductal dilation (n = 1). The mean age at presentation of patients undergoing surgery was 6.0 +/- 4.1 years (mean +/- SD). The mean time from presentation to operation was 3.3 +/- 3.3 years. There were no deaths after surgical intervention. Of 15 patients, 2 (13%) required rehospitalization within 90 days of surgery, one for bowel obstruction, the other for splenic infarction. The median length of stay postoperatively was 8 days (range, 5-66 days). Chronic pancreatitis in children differs markedly in etiology when compared with adults. In most cases seen in our institution, chronic pancreatitis resulted from ineffective ductal drainage. These disorders are amenable to surgical decompression, which, ultimately, can prevent disease recurrence.

Idiopathic diaphragmatic paralysis: Bell's palsy of the diaphragm?

Crausman, Robert S; Summerhill, Eleanor M; McCool, F Dennis

2009-01-01

Idiopathic diaphragm paralysis is probably more common and responsible for more morbidity than generally appreciated. Bell's palsy, or idiopathic paralysis of the seventh cranial nerve, may be seen as an analogous condition. The roles of zoster sine herpete and herpes simplex have increasingly been recognized in Bell's palsy, and there are some data to suggest that antiviral therapy is a useful adjunct to steroid therapy. Thus, we postulated that antiviral therapy might have a positive impact on the course of acute idiopathic diaphragm paralysis which is likely related to viral infection. Three consecutive patients with subacute onset of symptomatic idiopathic hemidiaphragm paralysis were empirically treated with valacyclovir, 1,000 mg twice daily for 1 week. Prior to therapy, diaphragmatic function was assessed via pulmonary function testing and two-dimensional B-mode ultrasound, with testing repeated 1 month later. Diaphragmatic function pre- and post-treatment was compared to that of a historical control group of 16 untreated patients. All three subjects demonstrated ultrasound recovery of diaphragm function 4-6 weeks following treatment with valacyclovir. This recovery was accompanied by improvements in maximum inspiratory pressure (PI(max)) and vital capacity (VC). In contrast, in the untreated cohort, diaphragm recovery occurred in only 11 subjects, taking an average of 14.9 +/- 6.1 months (mean +/- SD). The results of this small, preliminary study suggest that antiviral therapy with valacyclovir may be helpful in the treatment of idiopathic diaphragm paralysis induced by a viral infection.

Early pregnancy complications, defined as miscarriage, recurrent miscarriage or ectopic pregnancy, affect the physical and psychological well-being of intended parents. Research in this field so far has focused mainly on improving accuracy of diagnostic tests and safety and effectiveness of therapeutic management. An overview of aspects of care valued by women and/or their partners is missing. This systematic review aims to provide an overview of aspects of care valued by women and/or their partners faced with early pregnancy complications and to identify potential targets for improvement in early pregnancy healthcare. We searched five electronic databases for empirical quantitative or qualitative studies on patients' perspectives of early pregnancy care in July 2017. We first identified aspects of early pregnancy care valued by women and/or their partners based on qualitative and quantitative data and organized these aspects of care according to the eight dimensions of patient-centered care. Second, we extracted the assessment of service quality from women and/or their partners on each of these aspects of care based on quantitative data. Third, we combined the findings on patients' values with the findings of service quality assessment to identify potential targets for improvement in five groups according to how likely these targets are to require improvement. The search yielded 6240 publications, of which 27 studies were eligible for inclusion in this review. All included studies focused on miscarriage or recurrent miscarriage care. We identified 24 valued aspects of care, which all covered the eight dimensions of patient-centered care. The most frequently reported valued aspect was 'being treated as an individual person experiencing a significant life event rather than a common condition'. Assessment of service quality from women and/or their partners was available for 13 of the 24 identified aspects of care. Quantitative studies all documented service quality

How women who have experienced one or more miscarriages manage their feelings and emotions when they become pregnant again - a qualitative interview study.

The aim of this study was to investigate how women who have experienced one or more miscarriages manage their feelings when they become pregnant again. Individual qualitative interviews were conducted with 16 women who were pregnant again after experiencing one or more miscarriages. The interviews were analysed using qualitative content analysis with an inductive approach. The analysis of the material ended up in five categories: distancing herself from her pregnancy, focusing on her pregnancy symptoms, searching for confirming information, asking for ultrasound examination and asking for professional and social support. Because of their past experience with miscarriage, it could be painful to have another pregnancy terminate in disappointment. Therefore, the women manage their feelings by distancing themselves from their pregnancies. Simultaneously, they are managing their emotions by seeking affirmation that their current pregnancy is normal. Generally speaking, women manage their emotions by themselves. They feel isolated with their worries and concerns, and they are in need of the support provided from their intimate circle of friends and family as well as from the staff of the maternity health care ward. Unfortunately, the women do not feel that they get the support they need from the staff, instead they have to rely on their friends, family and partners to help them manage their emotions. © 2011 The Authors.

Little data exist on the progression of recurrent acute (RAP) and chronic pancreatitis (CP) from regions from where the entity of tropical chronic pancreatitis was originally described. The study aimed to follow up patients with RAP and CP seen at a southern Indian centre for progression of disease over time. Prospectively enrolled patients with RAP and CP were followed up, and the alcoholic and idiopathic subgroups were assessed for progression of structural and functional changes in the organ. One hundred and forty patients (RAP = 44; 31.4 %, CP = 96; 68.5 %) were followed up over a median 12.2 (interquartile range 12.0-16.8) months. The cause was alcohol in 31 (22.1 %) and not evident in 109 (77.8 %). The disease progressed from RAP to CP in 7 (15.9 %), 6 (16.2 %) out of 37 in the idiopathic and 1 (14.2 %; p = 1.00) out of 7 in the alcoholic subgroups. Three (42.8 %) and 1 (14.2 %) developed steatorrhea and diabetes mellitus (DM), respectively, and 2 (4.5 %) developed calcification. Established CP progressed in 19 (19.7 %), 1 (1.0 %), 5 (5.2 %), 2 (2.0 %) and 11 (11.4 %) newly developed DM, steatorrhea, calcification and duct dilation during follow up. Among the idiopathic and alcoholic CP, disease progression was seen in 15 (20.8 %) out of 72 and 4 (16.6 %) out of 24 respectively. Idiopathic RAP and CP progressed during the short-term follow up. This is similar to other etiological forms of pancreatitis, as described from elsewhere in the world.

Is acute recurrent pancreatitis in children a precursor of chronic pancreatitis? A long-term follow-up study of 93 cases.

In view of paucity of literature we analyzed our experience of acute recurrent pancreatitis (ARP) to study clinical profile and long-term outcome. Over 13 years, 93 consecutive children (≤18 years) diagnosed to have ARP were included in this study. Magnetic resonance cholangiopancreatography was done at baseline and on follow-up. Common mutations for serine-protease-inhibitor (SPINK1 N34S), protease inhibitor (PRSS1 R122S) and cystic fibrosis transmembrane conductance regulator (CFTR deltaF508, 5T) were studied in 22 idiopathic cases. The median age of the children with ARP was 13 (10-14.5) years, 53 were males. Etiology included biliary in 14 (15%), pancreas divisum in 6 (7%), others in 3 (3.5%) and idiopathic in the remaining 70 (75%). SPINK1 mutation was found in 10/22 (45%) cases. Over a median follow-up of 25.5 (8.25-48) months, 37 (42%) of 88 (5 lost to follow-up) developed chronic pancreatitis (CP). On multivariate analysis idiopathic etiology (p<0.03), presence of SPINK1 mutation (p=0.01), longer follow-up (p<0.001) were associated with progression to CP. Biliopancreatic structural/obstructive causes should always be looked for. It seems ARP is a precursor of CP and progression is associated with idiopathic etiology and presence of genetic mutations. Hence, patients with ARP should be kept on regular follow-up to detect CP. Copyright © 2017 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

The objective is the description and summary of the current state of idiopathic scoliosis treatment with physical therapy based on new scientific knowledge and concluded from more than 15 years of experience as a leading physician in two well-known clinics specializing in the conservative treatment of scoliosis. Based on current scientific publications on physical therapy in scoliosis treatment and resulting from the considerable personal experience gained working with conservative treatment and consulting scoliosis patients (as inpatients and outpatients), the current methods of physical therapy have been compared and evaluated. Physical therapy according to Schroth and Vojta therapy are at present the most common and effective methods in the physical treatment of idiopathic scoliosis. These methods can be applied during inpatient or outpatient treatment or intensified in the practice of specialized therapists. As there are only a few scientific studies on this subject, the author's findings are based mainly on his own experiences of the conservative treatment of idiopathic scoliosis. Athough these experiences are the results of over 15 years of working in the field of therapy, and the Schroth method in combination with corrective bracing presents highly promising results, it would nevertheless be desirable to conduct detailed scientific studies to verify the effectiveness of conservative treatment.

Obesity at age 20 and the risk of miscarriages, irregular periods and reported problems of becoming pregnant: the Adventist Health Study-2.

In a group of 46,000 North-American Adventist women aged 40 and above, we investigated the relationships between body mass index (BMI, kg/m(2)) at age 20 and the proportion of women who reported at least one miscarriage, periods with irregular menstruation or failing to become pregnant even if trying for more than one straight year. Approximately 31, 14 and 17 %, respectively, reported the three different problems related to reproduction. Positive age- and marital status adjusted relationships were found between BMI at age 20 and periods with irregular menstruation or failing to become pregnant even if trying for more than 1 year, but not with the risk of miscarriages. Women with BMI ≥ 32.5 kg/m(2) when aged 20 had approximately 2.0 (95 % CI: 1.6, 2.4) and 1.5 (95 % CI: 1.3, 1.9) higher odds for irregular periods or failing to get pregnant, respectively, than women with BMI in the 20-24.9 kg/m(2) bracket. These relationships were consistently found in a number of strata of the population, including the large proportion of the women who never had smoked or never used alcohol. Underweight (BMI < 18.5 kg/m(2)) when aged 20 marginally (approximately 15 %) increased the risk of failing to get pregnant within a year. Thus, obesity at age 20 increases the risk of reporting some specific reproductive problems, but not the risk of miscarriages.

Miscarriage and occupational activity: a systematic review and meta-analysis regarding shift work, working hours, lifting, standing, and physical workload.

Previous studies have indicated that shift work, long working hours, and prevalent workplace exposures such as lifting, standing, and physical workload increase the risk of miscarriage, but the evidence is conflicting. We conducted a systematic review of original research reports. A search in Medline and EMBASE 1966-2012 identified 30 primary papers reporting the relative risk (RR) of miscarriage according to ≥1 of 5 occupational activities of interest. Following an assessment of completeness of reporting, confounding, and bias, each risk estimate was characterized as more or less likely to be biased. Studies with equivalent measures of exposure were pooled to obtain a weighted common risk estimate. Sensitivity analyses excluded studies most likely to be biased. Working fixed nights was associated with a moderately increased risk of miscarriage (pooled RR 1.51 [95% confidence interval (95% CI) 1.27-1.78, N=5), while working in 3-shift schedules, working for 40-52 hours weekly, lifting >100 kg/day, standing >6-8 hours/day and physical workload were associated with small risk increments, with the pooled RR ranging from 1.12 (3-shift schedule, N=7) to 1.36 (working hours, N=10). RR for working hours and standing became smaller when analyses were restricted to higher quality studies. These largely reassuring findings do not provide a strong case for mandatory restrictions in relation to shift work, long working hours, occupational lifting, standing, and physical workload. Considering the limited evidence base, however, it may be prudent to advise women against work entailing high levels of these exposures and women with at-risk pregnancies should receive tailored individual counseling.

Both vascular endothelial growth factor A (VEGFA) and endocrine gland-derived vascular endothelial growth factor (EG-VEGF) systems play major roles in angiogenesis. A body of evidence suggests VEGFs regulate critical processes during pregnancy and have been associated with recurrent pregnancy loss (RPL). However, little information is available regarding the interaction of these two major major angiogenesis-related systems in early human pregnancy. This study was conducted to investigate the association of gene polymorphisms and gene-gene interaction among genes in VEGFA and EG-VEGF systems and idiopathic RPL. A total of 98 women with history of idiopathic RPL and 142 controls were included, and 5 functional SNPs selected from VEGFA, KDR, EG-VEGF (PROK1), PROKR1 and PROKR2 were genotyped. We used multifactor dimensionality reduction (MDR) analysis to choose a best model and evaluate gene-gene interactions. Ingenuity pathways analysis (IPA) was introduced to explore possible complex interactions. Two receptor gene polymorphisms [KDR (Q472H) and PROKR2 (V331M)] were significantly associated with idiopathic RPL (P<0.01). The MDR test revealed that the KDR (Q472H) polymorphism was the best loci to be associated with RPL (P=0.02). IPA revealed EG-VEGF and VEGFA systems shared several canonical signaling pathways that may contribute to gene-gene interactions, including the Akt, IL-8, EGFR, MAPK, SRC, VHL, HIF-1A and STAT3 signaling pathways. Two receptor gene polymorphisms [KDR (Q472H) and PROKR2 (V331M)] were significantly associated with idiopathic RPL. EG-VEGF and VEGFA systems shared several canonical signaling pathways that may contribute to gene-gene interactions, including the Akt, IL-8, EGFR, MAPK, SRC, VHL, HIF-1A and STAT3.

To evaluate the results of pars plana vitrectomy and membrane stripping for idiopathic and secondary preretinal macular membrane (PMM). Twenty one consecutive subjects (21 eyes) ranging in age from 40 to 78 (mean 66.9) with PMM underwent vitrectomy and membrane peeling. 17 cases had membranes that were considered idiopathic, and 4 cases were associated with other disorders: 3 occurred after successful retinal reattachment surgery, 1--after laserotherapy in the course of diabetic retinopathy. Visual acuity (VA), Amsler grid, and postoperative complications were assessed. The follow-up was 1 to 22 months, mean 5.7. Visual acuity improved postoperatively in 15 eyes (71.4%), at least two lines on the Snellen chart in 8 eyes (38.1%), entirely in patients with idiopathic PMM. It remained unchanged in 3 eyes (14.3%) and deteriorated in 3 eyes (14.3%). Eyes with transparent membrane showed greater visual improvement than opaque ones. The preoperative Amsler test was positive in 15 patients (71.4%), postoperatively--in 4 cases (19%). 2 idiopathic cases with VA of 0.7 showed postoperatively VA of 1.0. Complications included retinal detachment in 2 eyes (1 in idiopathic and 1 in secondary PMM), and development of nuclear sclerotic cataract in 2 eyes. At 6 months of follow-up, a residual membrane formation in 1 cases appeared. Macular pseudohole was observed in 1 eye with no impact on visual results. 1. Vitrectomy with membrane peeling for preretinal macular membrane provides improvement in visual acuity and reduces metamorphopsia 2. Thin, cellophane-like appearance of the membrane gives a better prognosis of visual function improvement.

Idiopathic hypersomnia: clinical features and response to treatment.

A recent American Academy of Sleep Medicine publication identified a need for research regarding idiopathic hypersomnia. We describe various clinical and polysomnographic features of patients with idiopathic hypersomnia, with an emphasis on response to pharmacotherapy. A retrospective review of our database initially identified 997 patients, utilizing "idiopathic hypersomnia", "hypersomnia NOS", and "primary hypersomnia" as keywords. The charts of eligible patients were examined in detail, and data were abstracted and analyzed. Response to treatment was graded utilizing an internally developed scale. Eighty-five patients were ultimately identified (65% female). Median (interquartile range) ages of onset and diagnosis were 19.6 (15.5) and 33.7 (15.5), respectively. During a median follow-up duration of 2.4 (4.7) years, 65% of patients demonstrated a "complete response" to pharmacotherapy as assessed by the authors' grading schema. Methylphenidate was most commonly used as a first-line agent prior to December 1998, but subsequently, modafinil became the most common first drug. At the last recorded follow-up visit, 92% of patients were on monotherapy, with greater representation of methylphenidate versus modafinil (51% vs. 32%). Among these patients, methylphenidate produced a higher percentage of "complete" or "partial" responses than modafinil, although statistical significance was not reached (38/40 [95%] vs. 22/25 [88%], respectively, p = 0.291). The majority of patients with idiopathic hypersomnia respond well to treatment. Methylphenidate is chosen more often than modafinil as final monotherapy in the treatment of idiopathic hypersomnia, despite the fact that it is less commonly used initially. Further prospective comparisons of medications should be explored.

A muscle biopsy is currently requested to assess the diagnosis of an idiopathic inflammatory myopathy overlapping with a systemic disease. During the past few years, the classification of inflammatory myopathy subtypes has been revisited progressively on the basis of correlations between clinical phenotypes, autoantibodies and histological data. Several syndromic entities are now more clearly defined, and the aim of the present review is to clarify the contribution of muscle biopsy in a setting of idiopathic inflammatory myopathies overlapping with systemic diseases.

To investigate obesity as susceptibility factor in patients with idiopathic AA amyloidosis. Clinical, biochemical and genetic data were obtained from 146 patients with AA amyloidosis. Control groups comprised 40 patients with long-standing inflammatory diseases without AA amyloidosis and 56 controls without any inflammatory disease. Patients with AA amyloidosis had either familial Mediterranean fever (FMF) or long-standing rheumatic diseases as underlying inflammatory disease (n = 111, median age 46 years). However, in a significant proportion of patients with AA amyloidosis no primary disease was identified (idiopathic AA; n = 37, median age 60 years). Patients with idiopathic AA amyloidosis were more obese and older than patients with AA amyloidosis secondary to FMF or rheumatic diseases. Serum leptin levels correlated with the body mass index (BMI) in all types of AA amyloidosis. Elevated leptin levels of more than 30 µg/l were detected in 18% of FMF/rheumatic + AA amyloidosis and in 40% of patients with idiopathic AA amyloidosis (p = .018). Finally, the SAA1 polymorphism was confirmed as a susceptibility factor for AA amyloidosis irrespective of the type of the disease. Obesity, age and the SAA1 polymorphism are susceptibility factors for idiopathic AA amyloidosis. Recent advances in treatment of FMF and rheumatic disorders will decrease the incidence of AA amyloidosis due to these diseases. Idiopathic AA, however, might be an emerging problem in the ageing and increasingly obese population.

Objective Pregnancy complications such as intra-amniotic infection, preeclampsia, and fetal intrauterine growth restriction (IUGR) account for most cases of preterm birth (PTB), but many spontaneous PTB cases do not have a clear etiology. We hypothesize that placental insufficiency may be a potential cause of idiopathic PTB. Methods Secondary analysis of 82 placental samples from women with PTB obtained from a multicenter trial of repeat versus single antenatal corticosteroids. Samples were centrally reviewed by a single placental pathologist masked to clinical outcomes. The histopathologic criterion for infection was the presence of acute chorioamnionitis defined as neutrophils marginating into the chorionic plate. Placental villous hypermaturation (PVH) was defined as a predominance of terminal villi (similar to term placenta) with extensive syncytial knotting. Idiopathic PTB comprised a group without another known etiology such as preeclampsia, IUGR or infection. Results Acute chorioamnionitis was observed in 33/82 (40%) cases. Other known causes of PTB were reported in 18/82 (22%). The remaining 31/82 (38%) were idiopathic. The frequency of PVH in idiopathic PTB (26/31=84%) was similar to cases with IUGR or preeclampsia (16/ 18=89%), but significantly more common than PVH in the group with acute chorioamnionitis (10/33=30%) (p<0.001). Conclusions PVH, which is a histologic marker of relative placental insufficiency, is a common finding in idiopathic PTB. PMID:23130816

To perform a genotype-phenotype correlation study in an X-linked congenital idiopathic nystagmus pedigree (pedigree 1) and to assess the allelic variance of the FRMD7 gene in congenital idiopathic nystagmus. Subjects from pedigree 1 underwent detailed clinical examination including nystagmology. Screening of FRMD7 was undertaken in pedigree 1 and in 37 other congenital idiopathic nystagmus probands and controls. Direct sequencing confirmed sequence changes. X-inactivation studies were performed in pedigree 1. The nystagmus phenotype was extremely variable in pedigree 1. We identified 2 FRMD7 mutations. However, 80% of X-linked families and 96% of simplex cases showed no mutations. X-inactivation studies demonstrated no clear causal link between skewing and variable penetrance. We confirm profound phenotypic variation in X-linked congenital idiopathic nystagmus pedigrees. We demonstrate that other congenital nystagmus genes exist besides FRMD7. We show that the role of X inactivation in variable penetrance is unclear in congenital idiopathic nystagmus. Clinical Relevance We demonstrate that phenotypic variation of nystagmus occurs in families with FRMD7 mutations. While FRMD7 mutations may be found in some cases of X-linked congenital idiopathic nystagmus, the diagnostic yield is low. X-inactivation assays are unhelpful as a test for carrier status for this disease.

A hypothesis that the thoracic idiopathic scoliosis is buckling phenomenon of the fourth mode induced by the growth of thoracic vertebral bodies was presented in the previous work by the authors using numerical simulations with finite element model of the spine. If the hypothesis is acceptable, sensitivity function with respect to the critical growth of thoracic vertebrae on the maximization problem of buckling load with the fourth buckling mode gives us useful information to improve and develop treatments for the idiopathic scoliosis. The numerical results analyzed by the finite element method demonstrated that the sensitivity function is high at the articular capsules of the intervertebral joints, the intervertebral disks, the costotransverse joints and the constovertebral joints around the apex of the curvature in the case of the thoracic idiopathic scoliosis.

Recurrent pregnancy loss (RPL) concerns ~3% of couples aiming at childbirth. In the current study, transcriptomes and miRNomes of 1st trimester placental chorionic villi were analysed for 2 RPL cases (≥6 miscarriages) and normal, but electively terminated pregnancies (ETP; n = 8). Sequencing was performed on Illumina HiSeq 2000 platform. Differential expression analyses detected 51 (27%) transcripts with increased and 138 (73%) with decreased expression in RPL compared to ETP (DESeq: FDR P < 0.1 and DESeq2: <0.05). RPL samples had substantially decreased transcript levels of histones, regulatory RNAs and genes involved in telomere, spliceosome, ribosomal, mitochondrial and intra-cellular signalling functions. Downregulated expression of HIST1H1B and HIST1H4A (Wilcoxon test, fc≤0.372, P≤9.37 × 10−4) was validated in an extended sample by quantitative PCR (RPL, n = 14; ETP, n = 24). Several upregulated genes are linked to placental function and pregnancy complications: ATF4, C3, PHLDA2, GPX4, ICAM1, SLC16A2. Analysis of the miRNA-Seq dataset identified no large disturbances in RPL samples. Notably, nearly 2/3 of differentially expressed genes have binding sites for E2F transcription factors, coordinating mammalian endocycle and placental development. For a conceptus destined to miscarriage, the E2F TF-family represents a potential key coordinator in reprogramming the placental genome towards gradually stopping the maintenance of basic nuclear and cellular functions.

Objective The aim of this systematic review was to assess the effect of interventions to reduce stress in pregnant women with a history of miscarriage. Design A systematic review of randomised controlled trials (RCTs). Data source A total of 13 medical, psychological and social electronic databases were searched from January 1995 to April 2016 including PUBMED, CENTRAL, Web of Science and EMBASE. Eligibility criteria This review focused on women in their subsequent pregnancy following miscarriage. All published RCTs which assessed the effect of non-medical interventions such as counselling or support interventions on psychological and mental health outcomes such as stress, anxiety or depression when compared with a control group were included. Stress, anxiety or depression had to be measured at least preintervention and postintervention. Results This systematic review found no RCT which met our initial inclusion criteria. Of the 4140 titles screened, 17 RCTs were identified. All of them were excluded. One RCT, which implemented a caring-based intervention, included pregnant women in their subsequent pregnancy; however, miscarriage was analysed as a composite variable among other pregnancy losses such as stillbirth and neonatal death. Levels of perceived stress were measured by four RCTs. Different types of non-medical interventions, time of follow-up and small sample sizes were found. Conclusion Cohort studies and RCTs in non-pregnant women suggest that support and psychological interventions may improve pregnant women’s psychological well-being after miscarriage. This improvement may reduce adverse pregnancy-related outcomes in subsequent pregnancies. However, this review found no RCTs which met our criteria. There is a need for targeted RCTs that can provide reliable and conclusive results to determine effective interventions for this vulnerable group. PMID:28882928

We report a case of a 66-year-old Caucasian female with a diagnosis of idiopathic orbital inflammatory disease (OID) refractory to azathioprine therapy. The coexistence of diabetes mellitus represented a relative contraindication to chronic prednisone use. After two infusions of rituximab, a chimeric anti-CD20+ antibody, ophthalmic signs and symptoms remarkably improved. To our knowledge, this is the first case of idiopathic OID successfully treated with rituximab.

Pathogenesis, Newly Recognized Etiologies, and Management of Idiopathic Anaphylaxis

Idiopathic anaphylaxis (IA) is a life-threatening allergic disease and the most common diagnosis given to patients following an anaphylactic event. The inability of the healthcare provider and the patient to identify the trigger for anaphylaxis makes standard allergen avoidance measures ineffectual. IA is diagnosed after other causes of anaphylaxis have been excluded. Mast cell activation syndromes (MCAS), mastocytosis, IgE to galactose-alpha-1,3-galactose (α-gal), and certain medications have recently been recognized as causes of anaphylaxis that were previously labeled idiopathic. This review will describe the epidemiology and proposed theories of pathogenesis for IA, its diagnostic approach, its clinical management, and examine newly recognized disorders that were previously labeled as idiopathic anaphylaxis.

MR venography in idiopathic intracranial hypertension: unappreciated and misunderstood

Higgins, J; Gillard, J; Owler, B; Harkness, K; Pickard, J

2004-01-01

Background: Venous sinus disease must be excluded before diagnosing idiopathic intracranial hypertension but is found only rarely in typical cases. Magnetic resonance venography (MRV) is the technique of choice for investigating this, and provides images that are diagnostic and easy to interpret. However, recent work using more invasive techniques has documented pressure gradients and stenoses in the lateral venous sinuses in many cases of idiopathic intracranial hypertension. Objective: To examine the reason for this discrepancy and to establish whether there are characteristic appearances on MRV in idiopathic intracranial hypertension that are routinely overlooked in clinical practice. Methods: MRVs from 20 patients with idiopathic intracranial hypertension were reviewed, unblinded, by two neuroradiologists, and their appearances rated for focal narrowings and signal gaps. A control group of 40 asymptomatic volunteers, matched for age and sex with the patient group, was recruited prospectively for MRV, and their scans rated in the same way. Results: The lateral sinuses presented a range of appearances with quite different distributions in the two groups (p<0.001). Bilateral lateral sinus flow gaps were seen in 13 of 20 patients with idiopathic intracranial hypertension and in none of 40 controls. Conclusions: A historical failure to use normal healthy controls to establish the boundaries between imaging artefact, normal anatomical variant, and disease means that the pathological significance of the different appearances of the lateral sinuses on MRV has not so far been appreciated.

The cause of recurrent pregnancy loss often remains unknown. Possibly, pathophysiological pathways are shared with other pregnancy complications. All women with secondary recurrent pregnancy loss (SRPL) visiting Leiden University Medical Center (January 2000-2015) were included in this retrospective cohort to assess whether women with SRPL have a more complicated first pregnancy compared with control women. SRPL was defined as three or more consecutive pregnancy losses before 22 weeks of gestation, with a previous birth. The control group consisted of all Dutch nullipara delivering a singleton (January 2000-2015). Information was obtained from the Dutch Perinatal Registry. Outcomes were preeclampsia, preterm birth, post-term birth, intrauterine growth restriction, breach position, induction of labor, cesarean section, congenital abnormalities, perinatal death and severe hemorrhage in the first ongoing pregnancy. Subgroup analyses were performed for women with idiopathic SRPL and for women ≤35 years. In all, 172 women with SRPL and 1 196 178 control women were included. Women with SRPL were older and had a higher body mass index; 29.7 years vs. 28.8 years and 25.1 kg/m 2 vs. 24.1 kg/m 2 , respectively. Women with SRPL more often had a post-term birth (OR 1.86, 95% CI 1.10-3.17) and more perinatal deaths occurred in women with SRPL compared with the control group (OR 5.03, 95% CI 2.48-10.2). Similar results were found in both subgroup analyses. The first ongoing pregnancy of women with (idiopathic) SRPL is more often complicated by post-term birth and perinatal death. Revealing possible links between SRPL and these pregnancy complications might lead to a better understanding of underlying pathophysiology. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Recurrent subconjunctival hemorrhages leading to the discovery of ocular adnexal lymphoma.

Subconjunctival hemorrhages commonly occur idiopathically or from causes including ocular surgery, trauma, anticoagulation medications, or a Valsalva maneuver. When a hemorrhage persists or recurs, a more extensive list of differential diagnoses must be considered. This report details a case in which persistent subconjunctival hemorrhages led to the discovery of ocular adnexal lymphoma. A 68-year-old white man presented with a 7- to 8-month history of a recurrent red left eye. There was no associated pain, discharge, or change in vision over that time. The right eye was never involved. An ocular examination of the left eye found a mild nasal subconjunctival hemorrhage and a salmon-pink-colored lesion involving the superior conjunctiva. Clinical findings, photos, magnetic resonance images, and histopathology results are presented and reviewed. The signs, symptoms, incidence, pathophysiology, treatment, and prognosis of ocular adnexal lymphoma are also discussed. Lymphomas can occur in a variety of sites in the body. It is well documented that primary tumors can originate in the ocular adnexa. Although not typical, the first sign in this case was a recurrent subconjunctival hemorrhage. The importance of a thorough ocular examination is paramount for a patient's ocular health and possibly the patient's life. Published by Elsevier Inc.

To evaluate the preoperative features, intraoperative management, and postoperative outcomes of recurrent macular holes that developed after initial successful repair with small-gauge vitrectomy techniques. We retrospectively reviewed 392 eyes with idiopathic macular holes successfully treated with small-gauge vitrectomy. Thirteen of these eyes underwent reoperation after macular hole reopening. We assessed patient demographics, visual acuity, postoperative anatomical success, potential precipitating clinical factors of hole reopening, and details of the surgical repairs of these eyes. Macular hole reopening occurred in 13 (3.3%) of 392 eyes in a mean of 28 months (range, 1-120 months) after initial repair. All 13 recurrent holes closed after a second vitrectomy, but 4 (31%) holes reopened again and had vitrectomy. Of these, 2 reopened a third time. Ultimately, 11 (85%) holes were closed at the most recent follow-up. The mean best-corrected visual acuity was 20/81 before initial repair, 20/148 after the first reopening, 20/115 after repair of the first reopening, and 20/55 after repair of >1 reopening. Ten of 13 (77%) patients had, or later developed, macular holes in the other eye during follow-up. Reoperation successfully achieved hole closure and ultimate visual improvement in most eyes with recurrent macular holes. Most patients with recurrent holes previously had, or later developed, full-thickness macular holes in the other eye.

This work identifies, among adolescents with idiopathic scoliosis, those demonstrating impaired sensorimotor control through a classification procedure comparing the amplitude of their vestibular-evoked postural responses. The sensorimotor control of healthy adolescents (n=17) and adolescents with idiopathic scoliosis (n=52) with either mild (Cobb angle≥15° and ≤30°) or severe (Cobb angle >30°) spine deformation was assessed through galvanic vestibular stimulation. A classification procedure sorted out adolescents with idiopathic scoliosis whether the amplitude of their vestibular-evoked postural response was dissimilar or similar to controls. Compared to controls, galvanic vestibular stimulation evoked larger postural response in adolescents with idiopathic scoliosis. Nonetheless, the classification procedure revealed that only 42.5% of all patients showed impaired sensorimotor control. Consequently, identifying patients with sensorimotor control impairment would allow to apply personalized treatments, help clinicians to establish prognosis and hopefully improve the condition of patients with adolescent idiopathic scoliosis.

We describe a patient with idiopathic hemifacial spasm (HFS) that was responsive to zonisamide treatment. A 65-year-old woman presented with a 4-year history of left-sided HFS developing gradually, starting from the upper facial muscles. After several analyses, the diagnosis of idiopathic HFS was made, and the clonazepam treatment (0.5 mg every 8 hours) was started, without a complete remission of symptoms. Therefore, zonisamide (150 mg twice a day for a 6-week period) was added, with a complete resolution. The rechallenge with zonisamide after its dechallenge confirmed its effectiveness. During follow-up, the patient remained symptom-free, with no adverse drug reactions. We suggest that zonisamide could represent a useful therapeutic option in the treatment of idiopathic HFS.

Approximately 205 million pregnancies occur each year in the worldwide. On the other hand, Spontaneous abortion has been reported in 15-20% of all diagnosed pregnancies. The most common cause of spontaneous abortion is chromosomal abnormalities of the embryo. Robertsonian translocation carriers specially 21-14 are the most common balanced rearrangement among the carrier couples with the history of spontaneous abortion. In order to search for balanced chromosomal rearrangement and cytogenetic disorders, 10 members of related family with consanguinity marriage with the history of recurrent miscarriage were assessed. Cytogenetic evaluation on the basis G-banding technique at high resolution was performed in 3 couples and their related family with the history of idiopathic RSA in order to postulate any balanced chromosomal rearrangement. six members of them appeared with robertsonian balanced translocation between chromosome No.21 to No. 14 with the karyotype of 45, XX, t (14, 21) and 45, XY, t (14, 21), which this results are in agreement with several similar works which claimed that the risk of spontaneous abortion in couples with balanced chromosomal rearrangements is higher compared with general population. Considering to results of present study, it seems as if the cytogenetic analysis of couples with the history of recurrent abortions should be suggested compulsory to estimate the probable presence of any chromosomal rearrangement. This offer wills valuable information for genetic consulting.

The mechanism by which pancreas divisum may lead to recurrent episodes of acute pancreatitis in a subset of individuals is unknown. Abnormalities of the cystic fibrosis gene product (CFTR) have been implicated in the genesis of idiopathic chronic pancreatitis. The aim of this study was to determine if CFTR function is abnormal in patients with pancreas divisum and recurrent acute pancreatitis (PD/RAP). A total of 69 healthy control subjects, 12 patients with PD/RAP, 16 obligate heterozygotes with a single CFTR mutation, and 95 patients with cystic fibrosis were enrolled. CFTR function was analyzed by nasal transepithelial potential difference testing in vivo. The outcomes of the PD/RAP patients following endoscopic and surgical treatments were concomitantly analyzed. Direct measurement of CFTR function in nasal epithelium in response to isoproterenol demonstrated that the values for PD/RAP were intermediate between those observed for healthy controls and cystic fibrosis patients. The median value was 13 mV for PD/RAP subjects, which was statistically different from healthy controls (22 mV, p= 0.001) and cystic fibrosis pancreatic sufficient (-1 mV, p < 0.0001) and pancreatic insufficient (-3 mV, p < 0.0001) patients. These results suggest a link between CFTR dysfunction and recurrent acute pancreatitis in patients with pancreas divisum and may explain why a subset of patients with pancreas divisum develops recurrent acute pancreatitis.

Recurrent acute pancreatitis: an approach to diagnosis and management.

PubMed

Kedia, Saurabh; Dhingra, Rajan; Garg, Pramod Kumar

2013-01-01

Recurrent acute pancreatitis (RAP) is defined as more than two attacks of acute pancreatitis (AP) without any evidence of underlying chronic pancreatitis (CP). As the known causes of AP are generally taken care of, RAP usually occurs in the idiopathic group, which forms 20%-25% of cases of AP. The causes of idiopathic RAP (IRAP) can be mechanical, toxic-metabolic, anatomical, or miscellaneous. Microlithiasis commonly reported from the West is not a common cause of IRAP among Indian patients. Pancreas divisum (PD) is now believed as a cofactor, the main factor being associated genetic mutations. The role of Sphincter of Oddi dysfunction (SOD) as a cause of IRAP remains controversial. Malignancy should be ruled out in any patient with IRAP > 50 years of age. Early CP can present initially as RAP. The work-up of patients with IRAP includes a detailed history and investigations. Primary investigations include liver function tests (LFT), serum calcium and triglyceride, abdominal ultrasonography (USG) and contrast-ehhanced computed tomography (CECT) abdomen. Endoscopic ultrasound (EUS), magnetic resonance cholangiopancreatography (MRCP) and possibly endoscopic retrograde cholangiopancreatography (ERCP) are indicated in the secondary phase if the work-up is negative after the primary investigations. EUS is advised usually 6-8 weeks after an acute episode. Treatment of patients with IRAP is aimed at the specific aetiology. In general, empirical cholecystectomy should be discouraged with the availability and widespread use of EUS. Endoscopic sphincterotomy is advised if there is strong suspicion of SOD. Minor papilla sphincterotomy should be carried out in those with PD but with limited expectations. Regular follow-up of patients with IRAP is necessary because most patients are likely to develop CP in due course.

Multiple idiopathic external root resorption is a rare pathological condition usually detected as an incidental radiographic finding. External root resorption of permanent teeth is a multifactorial process related to several local and systemic factors. If an etiological factor cannot be identified for root resorption, the term "idiopathic" is applied. This report presents a case of multiple idiopathic apical root resorption. The condition was found in a young female patient seeking orthodontic treatment due to malocclusion. This kind of resorption starts apically and progresses coronally, causing a gradual shortening and rounding of the remaining root. Patients with this condition are not the ideal candidates for orthodontic treatment; however, the aim of this report is to describe an unusual case of idiopathic root resorption involving the entire dentition, and to present the orthodontic treatment of this patient. It describes the progress and completion of orthodontic therapy with satisfactory end results.

Patients with a first episode of acute pancreatitis can develop recurrent or chronic pancreatitis (CP). However, little is known about the incidence or risk factors for these events. We performed a cross-sectional study of 669 patients with a first episode of acute pancreatitis admitted to 15 Dutch hospitals from December 2003 through March 2007. We collected information on disease course, outpatient visits, and hospital readmissions, as well as results from imaging, laboratory, and histology studies. Standardized follow-up questionnaires were sent to all available patients to collect information on hospitalizations and interventions for pancreatic disease, abdominal pain, steatorrhea, diabetes mellitus, medications, and alcohol and tobacco use. Patients were followed up for a median time period of 57 months. Primary end points were recurrent pancreatitis and CP. Risk factors were evaluated using regression analysis. The cumulative risk was assessed using Kaplan-Meier analysis. Recurrent pancreatitis developed in 117 patients (17%), and CP occurred in 51 patients (7.6%). Recurrent pancreatitis developed in 12% of patients with biliary disease, 24% of patients with alcoholic etiology, and 25% of patients with disease of idiopathic or other etiologies; CP occurred in 3%, 16%, and 10% of these patients, respectively. Etiology, smoking, and necrotizing pancreatitis were independent risk factors for recurrent pancreatitis and CP. Acute Physiology and Chronic Health Evaluation II scores at admission also were associated independently with recurrent pancreatitis. The cumulative risk for recurrent pancreatitis over 5 years was highest among smokers at 40% (compared with 13% for nonsmokers). For alcohol abusers and current smokers, the cumulative risks for CP were similar-approximately 18%. In contrast, the cumulative risk of CP increased to 30% in patients who smoked and abused alcohol. Based on a retrospective analysis of patients admitted to Dutch hospitals, a first

Juvenile idiopathic arthritis is a systemic pathology of connective tissue characterized by a chronic inflammatory process with an autoimmune background whereas multiple sclerosis is a demyelination disease with an important role of immune disorders in its pathogenesis. The etiology in both cases remains unknown. The coincidence of juvenile idiopathic arthritis and multiple sclerosis was described a just a few patients. We now report on a 31-year-old woman with juvenile idiopathic arthritis and multiple sclerosis. In the present case, the main problem was to find the right proper medication for a very, aggressive course of multiple sclerosis and for arthritis. Treatment with interferon-beta and methylprednisolone led to remission with just minor side-effects.

Stroke in children is a relatively uncommon condition and frequently associated with other diseases like cardiopathies, sickle cell disease and chronic smoking. In contrast to stroke in adults, it is rarely caused by atherosclerosis, hypertension or diabetes mellitus. Childhood stroke of unknown causes is called idiopathic stroke. The etiology of idiopathic stroke is unknown. However, several so-called idiopathic diseases develop on the basis of a genetic predisposition. As an approach to investigate this possibility in idiopathic childhood ischemic stroke, we studied the relationship between clinical and immunogenetic features in this disease. We demonstrate that the gene frequencies and relative risk of HLA-B51 were markedly increased in our patients compared with controls (p < 0.001). Thirteen of seventeen HLA-B51-positive patients had had a preceding respiratory infection, which was a higher proportion than in the control group (p < 0.05). In the patient group, the alleles HLA-DRB1*0802, -DRAI*0401 and -DQBI*0402 were also significantly increased, defining the haplotype DRB1*0802-DRA1*0401-DQB1*0402 as a high-risk haplotype for idiopathic childhood ischemic stroke. Transient viral or bacterial infections, which involve vasculitis and vascular occlusion in the brain, can trigger idiopathic childhood ischemic stroke on the basis of an genetic predisposition.

Idiopathic calcinosis cutis refers to progressive deposition of crystals of calcium phosphate in the skin and other areas of the body, in the absence of any inciting factor. Idiopathic calcinosis cutis may sometimes take the form of small, milia-like lesions. Most commonly, such milia like lesions are seen in the setting of Down syndrome. Herein, we report a 5-year-old girl with multiple asymptomatic discrete milia-like firm papules distributed over the face and extremities. A diagnosis of milia-like idiopathic calcinosis cutis associated with Down Syndrome was provisionally made and was confirmed by histopathology and karyotyping.

Systemic juvenile idiopathic arthritis is a rare febrile arthritis of childhood characterized by a potentially severe course, including prolonged glucocorticoid exposure, growth failure, destructive arthritis, and life-threatening macrophage activation syndrome. Early cytokine-blocking biologic therapy may improve long-term outcomes, although some systemic juvenile idiopathic arthritis patients respond well to non-biologic treatment, leaving optimal management undefined. Consequently, treatment of new-onset systemic juvenile idiopathic arthritis by expert clinicians varies widely. To describe a pragmatic, observational comparative effectiveness study that takes advantage of diversity in the management of a rare disease: FiRst-Line Options for Systemic juvenile idiopathic arthritis Treatment (FROST), comparing non-biologic and biologic consensus treatment plans for new-onset systemic juvenile idiopathic arthritis within the 60-center Childhood Arthritis and Rheumatology Research Alliance Registry (CARRA). FiRst-Line Options for Systemic juvenile idiopathic arthritis Treatment (FROST) is a multicenter, prospective, non-randomized study that compares four Childhood Arthritis and Rheumatology Research Alliance (CARRA) consensus treatment plans for new-onset systemic juvenile idiopathic arthritis: (1) glucocorticoids alone, (2) methotrexate, (3) interleukin-1 blockade, and (4) interleukin-6 blockade. Patients consenting to participation in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry are started on one of four Consensus Treatment Plans at the discretion of the treating physician. The outcome of primary interest is clinically inactive disease off glucocorticoids at 9 months, comparing non-biologic (Consensus Treatment Plans 1 + 2) versus biologic (Consensus Treatment Plans 3 + 4) strategies. Bayesian analytic methods will be employed to evaluate response rates, using propensity scoring to balance treatment groups for potential

Celiac disease has been associated with numerous unfavorable health outcomes, including pregnancy complications such as infertility, preterm birth, and preeclampsia. However, the association between celiac disease and recurrent pregnancy loss (RPL) remains uncertain. Our purpose was to compare serum markers of celiac disease in women with and without RPL. Therefore, we performed a case-control study of 116 women with unexplained recurrent pregnancy loss and 116 age-matched controls. Maternal sera were analyzed for immunoglobulin A (IgA) and immunoglobulin G (IgG) tissue transglutaminase (tTG) antibodies and endomysial (EM) antibodies. Groups were similar with regard to age, race and ethnicity, and BMI. One case and one control tested positive (≥20 Units) for IgA tTG antibodies and mean levels of IgA tTG antibodies were similar in cases and controls (5.5±2.86 versus 6.0±12.45; p=0.16). No cases or controls were positive for IgG tTG antibodies. However, cases had higher levels of IgG tTG antibody compared with controls (4.0±2.40 versus 3.3±1.30; p=0.0064). One subject (a control) tested positive for IgA EM antibodies and no subjects tested positive for IgG EM antibodies. In conclusion, positive results for tTG and EM antibodies were similar in women with and without RPL. Given these results, testing for occult celiac disease is not recommended in the evaluation of women with idiopathic RPL. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

The aim of this study was to evaluate the medium-term results and complications of open inguinal varicocelectomy, including vein ligation, intraoperative venography, and antegrade sclerotherapy. Sixty-four children were treated between 2000 and 2009 for idiopathic varicocele. Fifty children were examined 6 months after surgery. In 2010, 22 patients were recalled for testicular ultrasound scans (US) to evaluate the medium-term results of the technique. The mean age of the children was 12.8 years at first consultation. Of the 50 cases, 35 children were asymptomatic, 13 experienced pain, 3 suffered from discomfort, and 1 had testicular asymmetry. Thirteen children had delayed left testicular growth compared with the right testis. The mean age at surgery was 13.3 years, and follow-up duration was 8.3 months ± 13.9. Thirty-eight patients achieved good results postsurgery; there was varicocele recurrence in 3, testicular hypotrophy in 7, and complete testicular atrophy in 2 patients. Naked eye inguinal surgical ligation does not appear to be safe enough to treat young adolescents, with the theoretical risk of a decrease in fertility in the future. In teams which are untrained in microsurgical or laparoscopic varicocelectomy, we suggest referring adolescent patients to a radiologist for embolization.

To describe the complications, and their incidence, associated with the management and delivery of a distinct second-trimester miscarriage cohort. A retrospective cohort study was undertaken in a large, tertiary-referral university hospital (8500 deliveries per annum). All cases of pregnancy loss occurring between 14(+0) and 23(+6) were identified from July 2009 to June 2013 (n = 181). Medical notes were reviewed and the number of complications among this cohort was identified. Logistic regression was conducted to assess associations with clinical presentation and management. The mean gestation of loss was 18(+2) weeks (SD: 2(+2)). 64.6% (n = 117) of the total losses were of intrauterine fetal demise (IUFD) with 17.7% (n = 32) following preterm premature rupture of membranes (PPROM) and 17.7% (n = 32) following preterm labour (PTL). All women required inpatient admission with 59.1% (n = 107) undergoing medical induction of labour. PPROM cases, compared with cases of IUFD, had increased odds of requiring antibiotic therapy (OR 13.75, 95% CI: 4.88-38.72) and readmission (OR OR 4.15, 95% CI 1.12-15.36). These women represent a small proportion of the obstetric population but remain a distinct cohort whose management is complicated by high rates of morbidity requiring medical intervention. An awareness of these risks should inform future clinical practice.

Idiopathic hypertrophic pachymeningitis presenting with occipital neuralgia.

Although occipital neuralgia is usually caused by degenerative arthropathy, nearly 20 other aetiologies may lead to this condition. We present the first case report of hypertrophic pachymeningitis revealed by isolated occipital neuralgia. Idiopathic hypertrophic pachymeningitis is a plausible cause of occipital neuralgia and may present without cranial-nerve palsy. There is no consensus on the treatment for idiopathic hypertrophic pachymeningitis, but the usual approach is to start corticotherapy and then to add immunosuppressants. When occipital neuralgia is not clinically isolated or when a first-line treatment fails, another disease diagnosis should be considered. However, the cost effectiveness of extended investigations needs to be considered.

From bad to worse: when lung cancer complicates idiopathic pulmonary fibrosis.

Patients with idiopathic pulmonary fibrosis have a significantly increased risk for the development of lung cancer. The morbidity and mortality of this disease combination are substantial, and, unfortunately, there are currently few data to help guide clinicians in its diagnosis and treatment. In a recent issue of this journal, Hwang et al presented one of the first studies to evaluate lung cancer in patients with idiopathic pulmonary fibrosis at the molecular level. They demonstrate variants in regulators of the cell cycle, which are known to be important in malignant transformation and may also be important in the pathogenesis of idiopathic pulmonary fibrosis. Further understanding of the pathogenic overlap between lung cancer and idiopathic pulmonary fibrosis could help point the direction to specific diagnostic modalities and targeted treatment of both conditions in the future.

To review clinicopathological features of all cases diagnosed as idiopathic granulomatous lobular mastitis (IGLM) in our hospital and compare them with other data from the Kingdom of Saudi Arabia. Reports of all breast specimens received in histopathology laboratory in Qatif Central Hospital, Kingdom of Saudi Arabia over a 14 year period (1988 through to 2002) were collected and those diagnosed as IGLM were selected for analysis of both pathological material and clinical data. Eleven patients representing 1.6% of all breast specimens were diagnosed as IGLM. The mean age was 35 years (range 25-50). Both breasts were equally affected. The most frequent presenting symptom was a breast mass of 2-22 weeks duration. The most common clinical diagnosis was chronic abscess (5 patients). Relation to pregnancy, lactation or oral contraceptives pills was elicited in 4 patients. Recurrence at different time intervals occurred in 3 patients. Microscopically there was an evident granulomatous inflammation mostly in lobular distribution. Ductal inflammation with epithelial changes was noted in most cases. Staining and cultures were negative for both mycobacterium and fungal organisms. Granulomatous mastitis is not unheard of and clinicians should keep it in their list of differential diagnosis of breast lumps so appropriate handling of breast specimens including microbiological studies can be pursued. Utility of fine needle aspiration biopsy as a diagnostic tool is to be considered.

To evaluate clinical signs, describe lesions and differences in the magnetic resonance imaging appearance of spinal new bone formations classified as disseminated idiopathic spinal hyperostosis and/or spondylosis deformans on radiographs and compare degeneration status of the intervertebral discs using the Pfirrmann scale. Retrospective analysis of 18 dogs presented with spinal disorders using information from radiographic and magnetic resonance imaging examinations. All dogs were found to be affected with both disseminated idiopathic spinal hyperostosis and spondylosis deformans. Neurological signs due to foraminal stenosis associated with disseminated idiopathic spinal hyperostosis were found in two dogs. Spondylosis deformans was associated with foraminal stenosis and/or disc protrusion in 15 cases. The Pfirrmann score on magnetic resonance imaging was significantly higher in spondylosis deformans compared with disseminated idiopathic spinal hyperostosis and signal intensity of new bone due to disseminated idiopathic spinal hyperostosis was significantly higher compared to spondylosis deformans. Differences between disseminated idiopathic spinal hyperostosis and spondylosis deformans found on magnetic resonance imaging contribute to an increased differentiation between the two entities. Clinically relevant lesions in association with disseminated idiopathic spinal hyperostosis were rare compared to those seen with spondylosis deformans. © 2014 British Small Animal Veterinary Association.

To assess current studies on the relationship between cell-derived microparticles (cMP) and recurrent miscarriages (RM) and pre-eclampsia (PE), and review the relationships between cMP and inflammatory and clot pathways, antiphospholipid antibodies (aPL), cytokines, and pregnancy complications. Systematic and comprehensive review of the literature from January 2000 to January 2012. Vall d'Hebron University Hospital. Women with recurrent miscarriages or PE, healthy nonpregnant women, and healthy pregnant women. None. Comparison of cMP numbers and types among groups. Platelet and endothelial cMP are increased in women with normal pregnancies compared with nonpregnant healthy women. Only five case-control studies regarding cMP and RM and 16 on cMP and PE were found to match our objective. Three of five articles referring to RM showed differences in cMP numbering, and 13 of 16 on cMP and PE showed differences in some type of cMP compared with controls. Cell-derived microparticles were raised in normal pregnancy. Recurrent miscarriage seems to be related to endothelial and platelet cell activation and/or consumption. An increase in almost all cMP types was observed in PE. A relationship between cMP and endothelial activation and proinflammatory status seems to exist.

Idiopathic hypersomnia is an uncommon sleep disorder characterized by prolonged sleep time and excessive daytime sleepiness without cataplexy. This study concerned a case of familial occurrence. The proband expressed an idiopathic hypersomnia with long sleep time at the age of 12 years. Clinical interview and ad libitum polysomnographic study did not reveal any symptoms of narcolepsy or other sleep disorders. Family history revealed that a 20-year-old sister had experienced symptoms of hypersomnia from the age of 16 and their mother had been diagnosed with idiopathic hypersomnia previously. The diagnosis of idiopathic hypersomnia with long sleep time was confirmed in the sister by clinical interview and ad libitum polysomnography. Human leukocyte antigen (HLA) did not reveal the DQB1-0602 phenotype in the proband and relatives. This report confirms the hypothesis of a genetic predisposition in idiopathic hypersomnia.

Multiscale recurrence quantification analysis of order recurrence plots

2017-03-01

In this paper, we propose a new method of multiscale recurrence quantification analysis (MSRQA) to analyze the structure of order recurrence plots. The MSRQA is based on order patterns over a range of time scales. Compared with conventional recurrence quantification analysis (RQA), the MSRQA can show richer and more recognizable information on the local characteristics of diverse systems which successfully describes their recurrence properties. Both synthetic series and stock market indexes exhibit their properties of recurrence at large time scales that quite differ from those at a single time scale. Some systems present more accurate recurrence patterns under large time scales. It demonstrates that the new approach is effective for distinguishing three similar stock market systems and showing some inherent differences.

Adolescent idiopathic scoliosis, a lateral curvature of the spine of unknown cause with a Cobb angle of at least 10°, occurs in children and adolescents aged 10 to 18 years. Idiopathic scoliosis is the most common form and usually worsens during adolescence before skeletal maturity. Severe spinal curvature may be associated with adverse long-term health outcomes (eg, pulmonary disorders, disability, back pain, psychological effects, cosmetic issues, and reduced quality of life). Early identification and effective treatment of mild scoliosis could slow or stop curvature progression before skeletal maturity, thereby improving long-term outcomes in adulthood. To update the 2004 US Preventive Services Task Force (USPSTF) recommendation on screening for idiopathic scoliosis in asymptomatic adolescents. The USPSTF reviewed the evidence on the benefits and harms of screening for and treatment of adolescent idiopathic scoliosis. The USPSTF found no direct evidence on screening for adolescent idiopathic scoliosis and health outcomes and no evidence on the harms of screening. The USPSTF found inadequate evidence on treatment with exercise and surgery. It found adequate evidence that treatment with bracing may slow curvature progression in adolescents with mild or moderate curvature severity (Cobb angle <40° to 50°); however, evidence on the association between reduction in spinal curvature in adolescence and long-term health outcomes in adulthood is inadequate. The USPSTF found inadequate evidence on the harms of treatment. Therefore, the USPSTF concludes that the current evidence is insufficient and that the balance of benefits and harms of screening for adolescent idiopathic scoliosis cannot be determined. The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for adolescent idiopathic scoliosis in children and adolescents aged 10 to 18 years.

The KIR2DL4 receptor and its ligand HLA-G are considered important for fetal-maternal immune tolerance and successful pregnancy. The absence of a particular variant of KIR2DL4 might be a bad prognostic factor for pregnancy outcome. However, it could be compensated by the presence of the respective LILRB1 allele. Therefore, we investigated the KIR2DL4, LILRB1 and HLA-G polymorphisms in 277 couples with spontaneous abortion and 219 control couples by HRM, PCR-SSP and RFLP methods. We found a protective effect of women's heterozygosity in -716 HLA-G (p = 0.0206) and LILRB1 (p = 0.0131) against spontaneous abortion. Surprisingly, we observed more 9A/10A genotypes of KIR2DL4 gene carriers in the group of male partners from the miscarriage group in comparison to the men from the control group (p = 0.0288). Furthermore, there was no association of women's KIR2DL4 polymorphism with susceptibility to spontaneous abortion. Multivariate analysis indicated that women's -716 HLA-G and LILRB1 and men's KIR2DL4 9A/10A are important in terms of the protection or susceptibility to miscarriage, respectively (p = 0.00968). In conclusion, a woman's heterozygosity in HLA-G and LILRB1 might be an advantage for a success of reproduction, but the partner's heterozygosity in 9A/10A KIR2DL4 alleles might not.
