Abstract
Antibody cross-reactivity among flaviviruses is a major limitation in understanding the prevalence without vector control measures. In this study, we investigated the presence of Zika virus (ZIKV)-specific antibodies and the significance of their cross-reactivity with other flaviviruses, which could affect the serological specificity in both symptomatic and asymptomatic pregnant women. Among the results obtained from 217 serum samples tested for ZIKV-specific IgM and IgG, no specific predictions regarding seropositivity or exposure due to extensive cross-reactivity with dengue virus (DENV) serology could be made. Clear-cut positivity was observed in 1.8% (n = 4) and 1.0% (n = 2) for ZIKV IgM and IgG, respectively. The same samples assessed for DENV showed 1.3% (n = 3) seropositivity each for IgM and IgG levels. None of the samples were positive for ZIKV and DENV IgM or IgG. However, one sample (0.4%) tested positive for ZIKV and DENV IgM. No significant correlation was observed between DENV IgM and IgG when comparing the overlapped serotiters. On the other hand, the ZIKV IgG-positive sample showed higher serotiters for DENV IgG, indicating cross-reactivity with ZIKV but without statistical significance. Therefore, screening for the incidence of ZIKV becomes particularly challenging in a population where the presence or pre-exposure to DENV is observed. Our observations further suggest that unless flavivirus prevalence is properly addressed, determining the prevalence of ZIKV antibodies, which may be confounded with other uninvestigated flaviviruses, will be complicated.

Abstract
BACKGROUND Dysphagia is a distressing symptom during and after radiotherapy treatment in head and neck cancer (HNC) patients. The objective of this prospective study was to investigate whether swallowing sparing intensity modulated radiotherapy (SW-IMRT) reduces the occurrence of swallowing dysfunction compared to the standard IMRT (ST-IMRT). METHODS We randomized, planned, and treated patients with HNC who needed whole neck irradiation using the simultaneous integrated boost (SIB) IMRT technique. Doses of 70, 60, and 54 Gy (over 33 daily fractions) were prescribed to the primary tumor, high-risk and low-risk regions, respectively. The postoperative cases received 60 and 54 Gy (over 30 daily fractions) to the high-risk planning target volume (PTV) and low-risk PTV. We contoured organs at risk related to swallowing dysfunction (SWOARs) in all cases. In the ST-IMRT group, parotids only were spared. In the SW-IMRT group, parotids and SWOARs outside the high-risk PTV were spared. Assessment of dysphagia included clinical and instrumental evaluation. RESULTS One hundred forty-six patients ended their radiotherapy treatment. Dose distribution showed comparable PTV coverage and no difference in parotid glands sparing between the two groups. SWOARs dose reduction with SW-IMRT differs according to tumor location and its overlap with SWOARs. Using different assessment methods, SW-IMRT was associated with a lower occurrence of dysphagia up to one year after treatment. There was no difference between the two groups regarding acute dysphagia (p = 0.262), overall survival (p = 0.811), and disease-free survival (p = 0.876). CONCLUSION SW-IMRT is significantly better than ST-IMRT regarding a physician-rated and objective assessment of swallowing dysfunction at short- and long-term post-treatment follow-up.

Abstract
Abstract
Background
Cancer is the second most common cause of death among children aged 1–14 years in the USA. Pediatric malignancies have elevated morbidity and mortality in the absence of proper treatment. Intensive treatment regimens have resulted in a significant increase in the number of survivors but also have been associated with the risk of developing neurotoxicity. The purpose of this study is to emphasize the role of advanced MRI techniques in the early detection of different chemotherapy neurotoxicities and make radiologists aware of them providing early management to prevent permanent damage.
Results
We evaluated 63 patients (43 males and 20 females), and their ages ranged from (2 to 17 years) with suspected chemotherapy-related neurotoxicity. MR examinations were performed with 1.5-T Philips systems. Clinical data were correlated with magnetic resonance imaging (MRI), and different treatment complications were diagnosed. All of our 63 patients were receiving chemotherapy treatment, and they developed different neurological symptoms. Patients diagnosed as posterior reversible encephalopathy syndrome were 41 with 8 patients had typical and 33 had atypical criteria, 16 patients diagnosed as cerebral venous sinus thrombosis with magnetic resonance venography (MRV) are the most important sequence that successfully diagnosed them, and finally, 6 patients diagnosed as methotrexate neurotoxicity with diffusion-weighted images (DWI) are the most important sequence for early diagnosis.
Conclusion
Chemotherapy is associated with certain neurotoxicities, conventional MRI can detect them, but by the use of advanced MRI techniques including MRV and DWI early detection of these neurotoxicities can occur. Therefore, the combination of conventional MRI together with advanced techniques improves the diagnostic efficacy of MRI in the early diagnosis of neurotoxicity.

Abstract
OBJECTIVES The aim of this study was to assess the structural alteration of corpus callosum (CC) in adolescent females with Borderline Personality Disorder (BPD) and detect the relationship between these changes and BPD symptoms. METHODS A comparative case control study was conducted on 50 adolescent females that were divided into 2 groups; 25 outpatients suffering from BPD (according to DSM-IV-TR diagnostic criteria) compared to 25 healthy adolescents. All subjects were assessed by Borderline Personality Questionnaire, Barratt impulsivity scale-11, Brief Non-Suicidal Self-Injury Assessment tool, Beck Scale for Suicidal Ideation, and Diffusion tensor imaging. RESULTS Relative to control subjects, BPD patients had significantly lower fractional anisotropy (FA) values in the genu and lower mean diffusivity (MD) values in the body of CC. There was a negative correlation between FA values in the genu and body of CC and impulsivity. MD in the body of CC was positively correlated with motor impulsiveness and negatively correlated with suicidality. CONCLUSION Adolescent females with BPD show structural alterations in the CC that are related to symptoms of emotional dysregulation and impulsivity.

Abstract
Although dyslipidemia among offspring of parents with coronary heart disease (CHD) has been known, the development of this adverse relationship with respect to specific lipoprotein variables from childhood to young adulthood has not been elucidated. This aspect was examined in a young adult cohort with (n = 271) and without (n = 805) a parental history of CHD followed longitudinally since childhood by repeated surveys from 1973 to 1991. Trends in fasting lipoprotein variables by parental CHD status were assessed by Lowess smoothing curve and Generalized Estimating Equations (GEE). In multivariate analyses adjusted for race and sex, parental CHD associated positively with low-density lipoprotein cholesterol (LDL-C, P <.01) and triglycerides (P <.05) mainly at the young adulthood age, whereas a positive association was noted with very-low-density lipoprotein cholesterol (VLDL-C) during both childhood and young adulthood (P <.05). The positive association between parental CHD and LDL-C in young adulthood persisted independently of body mass index (BMI) and fasting insulin, but disappeared when fasting glucose was added to the model. With respect to triglycerides and VLDL-C, inclusion of BMI, insulin, and/or glucose eliminated the adverse association with parental CHD. These observations suggest that parental CHD is just one more explanatory variable that loses its partial contribution to lipoprotein profiles in their offspring when other strongly interrelated contributory variables such as age, body fatness, and measures of glucose homeostasis are taken into account. Information on these risk variables in conjunction with parental or family history of CHD may enhance the potential of CHD risk assessment in youth.

Abstract
BACKGROUND Perineal wound complications may occur after visceral pelvic surgery. We reviewed our experience to determine indications for immediate tissue transfer (TT) to prevent complications. METHODS Hospital records and computerized data were reviewed on 175 perineal repairs in 156 patients treated at The University of Texas M.D. Anderson Cancer Center for tumors involving the alimentary tract (135 of 175), genitourinary tract (15 of 175), perineum (19 of 175), or sacrum (6 of 175). Patients had either resection of only the colorectum and anus (APR) (46 of 175) or multivisceral resection (MVR) (129 of 175), and the perineal wound was closed by using TT (108 of 175) or primary closure (PC) (67 of 175) on the basis of the surgeon's judgment. Complications were compared between PC and TT groups. RESULTS Complications occurred in 57% (100 of 175). There was no significant difference overall in PC and TT procedures or in the APR subgroup. There were significantly fewer complications for TT patients in the MVR subgroup (P =.0001). There were significantly fewer complications for TT patients with prior irradiation in both APR (P =.01) and MVR (P =.007) subgroups. CONCLUSIONS Immediate TT for perineal wound closure is associated with fewer healing complications than PC in a subset of patients with multivisceral resection or prior radiotherapy. Surgical planning in these cases should consider immediate soft tissue reconstruction.

Abstract
Elevation of glucose concentration in diabetes may induce generation of oxygen free radicals such as superoxide (O2*-) and hydroxyl (*OH). The aim of the present study was to investigate the effect of the oxidative stress on the activities of blood superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GSSG-R) and aldose reductase, the levels of reduced glutathione (GSH), lipid peroxidation (thiobarbituric acid reactive substances; TBARS) and plasma levels of insulin-like growth factor-1 (IGF-1), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone in type 2 (non-insulin-dependent diabetes) patients and in healthy controls. Blood SOD, CAT, GSH-Px and GSSG-R were lower in type 2 diabetic patients compared with the the control group. Blood aldose reductase activity was elevated in patients with type 2 diabetes compared with the control group. GSH was decreased while TBARS concentration was increased in red blood cells (RBC) and leukocytes from the patients with type 2 diabetes mellitus in comparison to the control group. The mean values of plasma LH, FSH and testosterone were decreased, whereas the mean plasma IGF-1 concentration was increased in type 2 diabetes compared with controls. These findings support the hypothesis that hyperglycemia enhances the activity of the polyol pathway and impairs the antioxidant status, particularly glutathione redox cycle, resulting in poorer defense against oxidative stress. In addition, decreased circulating testosterone and gonadotropin levels may reflect the oxidative stress exerted by diabetes.

Abstract
It is well recognized that end-stage renal disease (ESRD) is associated with accelerated and malignant hypertension. The association of renal disease and what is considered as normal blood pressure is still not clear. The present study examined the temporal relation between blood pressure and renal function reflected by serum creatinine in a biracial (black-white) community-based population enrolled in the Bogalusa Heart Study. The study included 662 young adults aged 19 to 32 years, (white men, n = 188; white women, n = 289; black men, n = 67; and black women, n = 118) who were followed for an average of 7.4 years. In black men, partial correlation adjusted for age, body mass index, serum glucose, uric acid, and cigarette smoking showed that baseline systolic and diastolic blood pressure are not significantly related to baseline serum creatinine, but significantly related to serum creatinine at follow-up (r = 0.38, P = .008 and r = 0.42, P = .003, respectively). Multivariate regression analysis further showed a significant prediction of serum creatinine at follow-up by baseline systolic and diastolic blood pressure (0.031 mg/dL and 0.037 mg/dL rise in follow-up serum creatinine for every 10 mm Hg increase in systolic (P = .000) and diastolic (P = .001) blood pressure at baseline, but not the other way around. Other race and sex groups did not show such significant temporal relations. We conclude that in young black men, higher blood pressure levels within normal range precede and explain part of the increase in serum creatinine, a measure of decline in renal function. Thus, our results underscore the beneficial effect of maintaining blood pressure levels lower than what is considered as the upper normal limit, particularly in black men.

Abstract
This prospective comparative study was carried out to assess the value of sonohysterography (SHG) in evaluating both the endometrial cavity and tubal patency in infertile patients and to compare its results with hysterosalpingography (HSG), diagnostic hysteroscopy and laparoscopic chromopertubation. It comprised 84 infertile women who were examined using SHG the day before combined diagnostic laparoscopy and hysteroscopy. Eighty-three patients had had HSG within 6 months. As regards the appearance of the endometrial cavity, the results of SHG agreed with hysteroscopy in 72.2% (k = 0.31) while HSG agreed with hysteroscopy in 75.6% (k = 0.39) of cases. The appearance of the right and left tubes using SHG agreed with laparoscopy in 72.4% (k = 0.16) and 60.5% (k = 0.13), respectively, while HSG agreed with laparoscopy in 94% (k = 0.52) and 90.4% (k = 0. 51), respectively. However, when the appearance of fluid in DP was considered as an indirect indicator of patency of at least one tube at SHG, the agreement with laparoscopy rised to 88.1% (k = 0.24) and 85.7% (k = 0.18) for both tubes respectively. In conclusion, SHG is similar to HSG as regards the appearance of the endometrial cavity but it is inferior to it for evaluating tubal factor. The implication of SHG in the infertility work-up as a simple and fast procedure can minimize costs and abuses of sophisticated techniques particularly in the developing countries with limited resources.

Abstract
A total of 330 high-risk pregnant women with gestational ages of 32-42 weeks were followed until delivery using the biophysical profile (BPP) and a screening test consisting of the amniotic fluid index together with fetal acoustic stimulation under ultrasound M-mode scanning. The test was compared with the BPP and nonstress test (NST) for predicting abnormal outcome. The sensitivities of the BPP, NST and the proposed test were 100, 98.4 and 100%, respectively, the negative predictive values were 100, 99.4 and 100%, while the false-positive rates were 21.3, 39.3 and 67%. Our simplified biophysical testing method is suggested to be a good negative preliminary screening test, while positive results require further fetal testing methods. This test reduced the need for BPP in many high-risk patients and had the advantages of simplicity, low cost and less time consumption.

Abstract
OBJECTIVE Our purpose was to compare third-trimester fetal biophysical activities in normal and well-controlled insulin-dependent diabetic pregnancies. STUDY DESIGN We performed serial bimonthly fetal biophysical studies from 30 to 38 weeks in 18 normal and 18 well-controlled insulin-dependent diabetic pregnancies (White classes B through D). Each study contained 60 minutes of simultaneous ultrasonographic recordings of fetal breathing movements and rates, baseline heart rate, and body movements. Mean daily blood glucose levels of diabetic patients were determined from home monitors; HbA1c was determined every 6 weeks and ultrasonographic fetal growth rates every 3 weeks. Data were compared with t tests, analysis of variance with repeated measures, and chi 2 tests. RESULTS Women in the diabetic group maintained good glycemic control and were delivered of normal infants of weights similar to those of nondiabetic gravidas. Their fetuses had higher mean incidences of fetal breathing movement, fetal heart rates, and fetal breathing rates but lower fetal movements and fetal heart rate acceleration counts than did controls throughout the study. Neither short- nor long-term maternal glycemic levels correlated well with fetal biophysical performance. CONCLUSIONS In spite of good maternal glycemic control fetuses of diabetic women behaved differently from those of nondiabetic women. Modulation of their biophysical activities may be affected by maternal glycemic status before the last trimester. Different standards might need to be applied to interpret their tests.

Abstract
Semiquantitative amniotic fluid volume (AFV) determination is a component of the fetal biophysical profile (BPP). To assess decreased AVF we did BPPs of 174 fetuses within 1 week of delivery. Two methods were used: measurement of the single largest vertical pocket (oligohydramnios = depth < 1 cm) and the four-quadrant amniotic fluid index (AFI) (oligohydramnios = AFI < or = 5 cm). AFV, as determined by each method, was related to measures of fetal outcome (perinatal mortality, fetal distress, Apgar score, meconium-stained amniotic fluid, and intrauterine growth retardation [IUGR]). The AFI was more sensitive in predicting mortality (87.5%) and the following measures of perinatal morbidity: low 5-minute Apgar score (88.8%), fetal distress during labor (86.6%), meconium-stained amniotic fluid (63.6%), and the presence of IUGR (79.4%). The sensitivity of amniotic fluid pocket measurement of < 1 cm was 75%, 72.2%, 66.6%, 47.7%, and 55.8%, respectively, for the same measures. Using the AFI instead of a single pocket measurement in BPP assessment increased the sensitivity and positive predictive value of the BPP from 64.7% to 76.4% and from 45.8% to 68.4%, respectively. Our data suggest that qualitative AFV measurement using the AFI is superior to that of the single largest pocket in multiple component fetal biophysical testing.

Abstract
OBJECTIVE To determine whether uterine activity, assessed by either fluid-filled or solid pressure catheters, changes with uterine incision at cesarean delivery. METHODS Uterine activity was recorded continuously during low transverse cesarean delivery in ten parturients using fluid-filled pressure catheters and in ten women with solid pressure catheters. Visual analyses were performed of the last 30 minutes of uterine recording before uterine incision and of the period after incision; the analyses were then compared within and between the catheter groups for mean uterine tone and contraction amplitude, frequency, and duration. Oxytocin use, anesthesia method, mean gestational age, birth weight, length of labor, duration of monitoring, and uterine incision-to-delivery time were compared between the groups. RESULTS All obstetric end points were similar in both catheter groups except for a higher mean birth weight in the solid-catheter group. The mean (+/- standard deviation) duration of post-incision monitoring was 4.7 +/- 0.94 minutes. After uterine incision, mean tone and contraction amplitude were unchanged, whereas mean contraction frequency and duration decreased significantly. CONCLUSIONS Though intrauterine monitoring was brief, this model allows a unique view of "controlled" uterine rupture. Spontaneous uterine rupture may evolve more gradually; however, neither catheter type would be likely to aid its early recognition.

Abstract
OBJECTIVE Our objective was to determine the ability of biophysical profile variables to predict bad perinatal outcome in high-risk third-trimester pregnancy. STUDY DESIGN The outcomes of 1146 fetuses were correlated with abnormal single or multiple variables occurring in biophysical profile done within 72 hours of delivery. Theoretic risks of poor outcomes for different combinations of abnormal variables, calculated with Shortlife's formula, were compared with the actual risks observed (chi 2 tests). RESULTS Two hundred forty-six fetuses had at least one abnormal biophysical profile variable with the risk of bad outcome, for a single abnormal variable, ranging from 8% (body movements) to 100% (tone) and increasing from 14% (any variable abnormal) to 63% (all variables abnormal). In most (57%) observed combinations of biophysical profile variables, significant differences between theoretic and actual risks of bad outcomes were found. By stepwise logistic regression the best predictive model contained all variables except fetal movement. CONCLUSIONS Dynamic biophysical profile variables appear to be interdependent. Not all combinations of abnormal variables occur and specific combinations improve prediction of poor outcome. Risk-related scales for biophysical profile outcomes might prove superior to more conventional scoring systems.

Abstract
Superoxide dismutase (SOD) activity was measured in polymorphonuclear leucocytes (PMNLs) and mononuclear cells (MNCs) from 60 patients with rheumatoid arthritis (RA) and in 15 controls. In all patients and controls SOD activity (U/mg protein) in MNCs was twice that in PMNLs. SOD activity in PMNLs and in MNCs from patients with RA was significantly higher than that in controls. SOD activity in PMNLs (but not in MNCs) from patients treated with corticosteroids was significantly higher than that from patients treated with nonsteroidal anti-inflammatory drugs. There was no relation between SOD activity in both PMNLs and MNCs and either the patients' age, sex, duration of disease, serum immunoglobulin concentration, IgM rheumatoid factor, and copper level, or the degree of disease activity.

Abstract
Serum copper concentrations were measured in patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), osteoarthritis (OA), and in healthy controls. Median serum copper concentrations were raised significantly in RA and AS, but not in OA. Serum copper in RA correlated significantly with a number of disease activity markers--for example erythrocyte sedimentation rate (ESR), C-reactive protein, haemoglobin concentration, morning stiffness, and grip strength. It also correlated well with the overall disease activity as assessed by a composite index. Raised serum copper was associated with severe RA as manifested by the presence of immunoglobulin M rheumatoid factor, extra-articular features, weak grip and highly active disease. High serum copper might be related to the development of the pathological lesions observed in RA and not just be a secondary response.
