Abstract
AIM OF THE STUDY To assess the medium-term outcomes of ACE in children with fecal incontinence (FI). METHOD Eligible children were recruited from the colorectal clinic between December 2016 and January 2020 and were followed prospectively for 2-6 years. A series of questionnaires were used to assess QOL, patients and parent satisfaction, and to assess the outcomes of the ACE. RESULT 24 children aged 6-12 years (mean age 8.17 ± 1.95), including 18 males (75%) and 6 females (25% were studied. Cases included anorectal malformations (45.83%)., Hirschsprung disease (25%), neural tube defects (16.66%), sacrococcygeal teratoma (4.16%), and intractable pseudoincontinence (8.33%). QOL improved from (3) [3 -3] to (16) [16-16],p < 0.05. Fecal incontinence index showed significant improvement: 20 [20-20] versus 3 [0-4],p < 0.05. Bowel symptoms demonstrated improvement in the ability to decide when to pass stools and a decrease in soiling. Stooling survey showed lower scores representing better outcome. ACE questionnaire showed that the range of irrigation volumes used by parents is wide, and that all families recommend the ACE for children with similar condition. Postoperative complications were stenosis (16.66%), stomal prolapse (12.5%), leakage (4.16%), and false passage (4.16%). Satisfaction questionnaire showed a median score of 9 (range, 5-10). CONCLUSION ACE is an effective method to keep the child with FI clean, more socially active, and with a better QOL and FII in the medium-term. The reported complications were stenosis, false passage, and leakage. ACE mucosa prolapse is a novel complication picked up on medium-term follow up.

Abstract
Background Jejunoileal atresia (JIA) represents a common cause of neonatal bowel obstruction. There is a discrepancy between the diameters of the proximal and the distal bowel loops and this is managed with excision or tapering of the dilated proximal bowel loop. We aim primarily to evaluate the outcome of tapering enteroplasty (TE) in managing JIA and secondarily to compare the outcome of TE to non-TE. Materials and Methods A retrospective analysis of records of all neonatal admissions with JIA from January 2017 to December 2018 at a tertiary university children's hospital. Type and location of atresia, time to full enteral feeds, length of stay (LOS), complications, and outcome were assessed in TE and non-TE groups. Results Forty-one patients were included in the study; 29 (70.7%) cases had jejunal atresia and 12 (29.3%) had ileal atresia. Seventeen (41.4%) patients had TE. The median days to full feeds was 19; 28 in the TE group versus 16 in the non-TE group (P = 0.022). Four (9.7%) cases needed a re-exploration because of failure to start feeds; all in the non-TE group. The median LOS was 33 days for TE versus 22 days for non-TE (P = 0.101). Twenty-one cases (51.2%) developed a wound infection and showed a significantly longer median LOS of 29.5 versus 19 days (P = 0.019). Mortality was 7 (17.1%). Conclusions TE did not show a superior outcome when compared to resection of the dilated bowel. It was associated with longer time to reach full enteral nutrition and longer LOS.

Abstract
Abstract
Aim
to Assess the feasibility and safety of selective non-operative management in penetrating abdominal injuries and to identify a protocol for selection of patient’s candidates for non-operative management.
Method
In this comparative study 40 abdominal stab victims (admitted to Emergency Department of Alexandria Main University Hospital) were selected during 6 months period where 20 patients were suitable for non-operative management according to strict selection criteria whereas the other 20 patients were operated according to clinical and/or radiological indications or on basis of department protocol, the results were compared in view of final outcome.
Results
In our study, 15 patients were assigned for operative management according to selected clinical and/or radiological indications only 3 of them (20%) had non-therapeutic laparotomies, On the other hand, five patients were explored on basis of department protocol in violation of our indications for exploration; four of them (80%) were non-therapeutic. So, the rate of non-therapeutic laparotomies was significantly higher when done mandatory without selected clinical and radiological indications.
Conclusions
Assessment of vital signs together with abdominal examination are the most important and dependable tools in decision making in penetrating abdominal trauma patients. Patients with shock on admission (but responding to resuscitation), proved low grade solid organ injury (by CT), and proved intraperitoneal collection (by US or CT) could be managed conservatively regarding that they remain vitally and clinically stable. If failure of conservation occurs, it is usually during the 1st 24 hours after admission.

Abstract
OBJECTIVES The objective of this work is to develop a simple, sensitive and non-extractive spectrophotometric method for the determination of memantine HCl (MEM), clomipramine HCl (CLM) and fluvoxamine maleate (FLV). MATERIAL AND METHODS The proposed method was based on the formation of colored ion-pair complexes between the basic nitrogen of the target drugs and rose bengal (RB) dye in a weak acidic medium. RESULTS The formed complexes were measured at 576nm for MEM, CLM and at 575nm for FLV. The reaction conditions were optimized to obtain the maximum color intensity. Beer's law was obeyed in the range of 2-20, 1-16 and 6-30μg/mL for MEM, CLM and FLV, respectively. The limit of detection (LOD) was 0.476, 0.185, 0.806 and the limit of quantitation (LOQ) was 1.443, 0.559 and 2.443 for MEM, CLM and FLV, respectively. The composition ratio of the ion-pair complexes was found to be 1:1 as determined by Job's method. CONCLUSION The proposed method was applied successfully for the analysis of the cited drugs in pure and dosage forms. Results of the proposed method were statistically compared with the reported methods by applying student's t- and F-tests and no significant differences were observed.

Abstract
Abstract
Introduction
The study was to compare the accuracy of laparoscopy in staging and selecting patients diagnosed with malignant obstructive jaundice, to the traditional investigation.
Method
a prospective study conducted in the period between September 2017 and December 2018.30 patients, having malignant jaundice, were divided into two groups for cancer staging to assess their resectability and operability. Staging of 15 patients in group A was limited to conventional diagnostic methods, while 15 patients were in group B,where Laparoscopy was added.
Results
Results showed that the accuracy of routine investigations in staging was 73%, while that of laparoscopy was 93%.The number of cases under staged by imagings were 8 cases(these were 3 in Group A and 5 in group B) thus they were diagnosed as operable. On the other hand, just 1 case was misdiagnosed by the laparoscopy. Regarding the morbidity and mortality, there were variable complications among those who had unrequired laparotomies including one mortality case.on the other side,the incidence of complications were markedly decreased in group B,with no mortality incidence.
Conclusions
Diagnostic laparoscopy has a crucial role in staging people with malignant jaundice and may decrease the rate of unnecessary laparotomy in people found to have resectable disease by conventional imagings.

Abstract
Casestudy
A group of spindle cell tumors with characteristic morphologic features, co-expression of CD34 and S100 and recurrent gene rearrangements in RAF-1, BRAF, and NTRK has recently been described. These tumors were found to be previously labeled as malignant peripheral nerve sheath tumor, infantile fibrosarcoma or unclassified spindle cell sarcoma. We describe a case of a 25-year-old female who presented with a right thigh mass. She underwent an ultrasound-guided biopsy showing a spindle cell tumor with co-expression of CD34 and S100 and subsequently underwent resection of the mass. Gross examination showed a 7.5 cm multi-lobulated, tan-pink, hemorrhagic and fleshy mass. Histologically, the tumor was relatively well-demarcated and consisted of spindle cells with moderate to high cellularity in a patternless architecture. The spindle cells showed moderate to marked pleomorphism, pale amphophilic cytoplasm, ovoid-to-elongated nuclei with vesicular chromatin, and occasional prominent nucleoli. Areas of prominent perivascular and stromal hyalinization were seen. Mitotic activity was brisk with up to 33 mitoses per 10 high power fields. Necrosis representing approximately 5% of the mass was identified. On immunohistochemistry, the tumor cells showed strong and diffuse positivity for CD34 and S100 and were negative for SOX10, broad-spectrum cytokeratin, EMA, SMA, Desmin, STAT6, MUC4, TLE1, and H3K27me3 (retained nuclear expression). EIF2S2-NTRK3 fusion gene was detected using next generation sequencing analysis.
Conclusion
A few cases of NTRK3 spindle cell sarcomas, other than classic infantile fibrosarcoma, have been previously reported in the literature with fusion genes involving ETV6, EML4, and STRN, among others. A gene fusion involving NTRK3 and EIF2S2 has not been previously reported. NTRK3-fused sarcomas typically show high-grade morphology and aggressive clinical behavior. Identification of NTRK-fused sarcomas is clinically important, as these advanced tumors are potentially amenable to NTRK inhibition. In our case, patient received adjuvant post-operative radiation therapy and returned with lung metastasis 5 months after surgery.

Abstract
PURPOSE Antimicrobial resistance is a major concern that we are facing nowadays. This is due to antibiotic misuse and bacteria developing resistance to the commonly used antibiotics. This may lead to increased mortality and consumption of country resources. Implementation of an antimicrobial stewardship program [ASP] can limit the use of unnecessary antibiotics and subsequently decrease the infection rates with better patient outcome. We aimed to control antibiotic misuse, reduce infection rate, decrease drug costs, and reduce length of hospital stay in the ICU. METHODS We conducted a prospective study on the surgical neonatal ICU [SNICU] over a period of 6 months divided into pre-implementation phase, followed by an ASP phase, in which we applied the antibiotic guidelines approved by the ASP committee. Data were collected in the two phases and analyzed for demographics, compliance with guidelines, prescribed antibiotics, lab investigations, surgical site infection [SSI], length of stay and patient outcome. RESULTS Compliance to the guidelines was encountered in 86% and SSI rate decreased to 20%. Days of Therapy (DOT) per 1000 patient days showed a significant decrease in Ampicillin Sulbactam by 296 (p = 0.024), Imipenem by 220.34 (p = 0.024) and Vancomycin by 287.34 (p = 0.048). Drug cost showed a 1185.97 EGP decrease in the ASP period compared to the pre-implementation period (p = 0.714). Average LOS decreased in the ASP period by a mean difference of 2.5 (p = 0.027). CONCLUSION ASP implementation can control antibiotic misuse, decrease the medical care expenses and improve patient outcome. TYPE OF STUDY Clinical research paper. LEVEL OF EVIDENCE Level one.

Abstract
Abstract
Background
Hearing impairment ranks third on the list of chronic health conditions of the elderly, after arthritis and hypertension. As average lifespans increase, it is likely that the proportion of people with hearing loss will also increase. The purpose of the study was to develop, standardize, and apply an Arabic version of the Hearing Handicap Inventory for the Elderly (HHIE).
Results
The mean age of the 100 subjects included in the pretest was 64.92 ± 5.937 with age ranged from 60 to 84 years. The average score for each item (simple, clear, and relevant) for each separate question obtained more than 80% which is considered valid. One hundred percent of the participants reported that the entire inventory appeared simple, clear, and relevant, we further implied the jury opinion; the total score average of our jury for the entire inventory was calculated to determine the face validity of the questionnaire and found to be 89.81%. Responses of all participants for each question were collected and showed questions 8, 21, 6, 7, and 14 obtained the highest response results for both yes and sometimes. The HHIE showed high reliability (p value < 0.001) for all questions. The demographic data of the forty participants showed no statistically significant difference between the complaining group of hearing loss and the non-complaining group as regards age and gender. There was a highly statistically significant difference between the complaining group and the non-complaining group regarding the HHIE. The sensitivity of the HHIE was 79% for severe auditory handicapping and only 24% for mild-to-moderate auditory handicapping.
Conclusion
The developed Arabic version of the HHIE has high reliability, validity, simplicity, and clarity which found consistent with the original English questionnaire and it performed well in the detection of hearing loss in elderly Egyptians. It can be applied in a large population and for use in surveys.

Abstract
BACKGROUND The combination of a high birth rate and limited resources leads to a strain on health services with dire consequences to the patient. This study aimed to track the outcome of declined referrals at the tertiary center in the Cairo University Specialized Pediatric hospital. METHODS Data were collected prospectively on all declined surgical neonates at the tertiary center. The families were later contacted to document outcomes. Verbal consent was taken. FINDINGS Over a 12 month period from January 2017 to December 2017, 668 neonatal surgical referrals were received. Of these 278, (41·6%) were declined for lack of available places. The majority were cases of esophageal atresia with tracheoesophageal fistula (35%), followed by bowel obstruction (21%). Thirty-six cases were lost to follow up. Of the remaining 242 cases, 103 (42·5%) died, 63 (26%) were referred to public hospitals, 69 (28·5%) to private hospitals and seven (2·8%) were managed conservatively. CONCLUSIONS Nearly half of neonatal surgical cases die while waiting for surgical intervention. Cases were shared equally between the public and private sector. The collected data are crucial in planning service provision for neonates requiring surgical treatment. To the best of our knowledge, this is the first study from Egypt and the region to report the number and outcome of surgical neonates who do not get access to expert surgical services. The study outlines the burden of disease faced by a single pediatric surgery unit and documents the various congenital anomalies encountered as well as their outcome when treated elsewhere.

Abstract
Thoracoscopic repair of esophageal atresia is gaining popularity worldwide attributable to availability and advances in minimally invasive instruments. In this report, we presented our experience with thoracoscopic esophageal atresia/tracheoesophageal fistula (EA/TEF) repair in our tertiary care institute. A prospective study on short-gap type-C EA/TEF was conducted at Cairo University Specialized Pediatric Hospital between April 2016 and 2018. Excluded were cases with birth weight < 1500 gm, inability to stabilize physiologic parameters, or major cardiac anomalies. The technique was standardized in all cases and was carried out by operating team concerned with minimally invasive surgery at our facility. Primary outcome evaluated was successful primary anastomosis. Secondary outcomes included operative time, conversion rate, anastomotic leakage, recurrent fistula, postoperative stricture, and time till discharge. Over the inclusion period of this study, 136 cases of EA/TEF were admitted at our surgical NICU. Thoracoscopic repair was attempted in 76 cases. In total, 30 cases were pure atresia/long gap type-C atresia and were excluded from the study. Remaining 46 cases met the inclusion criteria and were enrolled in the study. Mean age at operation was 8.7 days (range 2-32), and mean weight was 2.6 Kg (range 1.8-3.6). Apart from five cases (10.8%) converted to thoracotomy, the mean operative time was 108.3 minutes (range 80-122 minute). A tension-free primary anastomosis was possible in all thoracoscopically managed cases (n = 41) cases. Survival rate was 85.4% (n = 35). Anastomotic leakage occurred in seven patients (17%). Conservative management was successful in two cases, while esophagostomy and gastrostomy were judged necessary in the other for five. Anastomotic stricture developed in five cases (16.6%) of the 30 surviving patients who kept their native esophagus. Despite the fact that good mid-term presented results may be due to patient selection bias, thoracoscopic approach proved to be feasible for management of short-gap EA/TEF. Authors of this report believe that thoracoscopy should gain wider acceptance and pediatric surgeons should strive to adopt this procedure.

Abstract
OBJECTIVES In the present study, an eco- friendly micellar liquid chromatographic technique was validated for separation and quantification of two drugs; namely ribavirin (RIV), and sofosbuvir (SBV) in pure form, pharmaceuticals containing them, human plasma and human urine. These drugs are administered co-administered for treatment of Hepatitis C virus (HCV) that causes hepatitis C in humans. MATERIAL AND METHODS These drugs were separated using Nucleosil 100-5 phenyl column. Sodium dodecyl sulphate (SDS) solution (0.05M, pH 7.0) containing triethylamine (0.3%) and n-butanol (10%) was used as a mobile phase with 1.2 mLmin-1 flow rate and 215nm detection wavelength. Nine minutes were required for resolving the two drugs from the matrix. RESULTS The method showed good linearity for RIV and SBV with correlation coefficients (r2) more than 0.9996 within the concentration ranges of (20-400) and (40-400) ngmL-1 in pure form, (30-300) and (50-300) ngmL-1 in human plasma and (20-400) and (40-400) ngmL-1 in human urine, respectively. CONCLUSION The recommended method was applied for examination of RIV and SBV in pure and pharmaceuticals. The obtained results were statistically matched with reported methods with no significant differences. Also, the recommended method was effectively applied for estimation of both drugs in spiked human urine and plasma without purification or extraction steps and real samples of plasma and urine of humans having therapy of RIV and SBV, as well as, performing tablets dissolution-rate tests with satisfactory results.

Abstract
AIM Mortality in infants born with gastroschisis (GS) in low-to-middle-income countries (LMICs) is high. This study aimed to assess factors which might affect outcome in Egypt in order to improve survival. METHODS A prospective study over a 15-month duration was completed. Variables assessed covered patient, maternal, antenatal, treatment, and complications. The Gastroschisis Prognostic Score (GPS) was used to predict outcome. A validated questionnaire was used to assess socioeconomic status. The main outcome was mortality. RESULTS Twenty-four cases were studied. Median gestational age was 37 (26-40) weeks, and 9 (38%) were preterm. Mortality occurred in 15 (62%) infants. Median transfer time was 8 (1.5-35) hours, and 64% survived if transferred before 8 h. Median maternal age was 20 (16-27) years. All families were of a low or very-low socioeconomic level. Only 25% had antenatal scans. Most cases were simple GS, and only 3 (12.5%) were complex GS. Median length of stay was 14 (1-52) days, TPN duration was 12 (0-49) days, and days to full feeds was 5 (3-11) days. The GPS score ranged from 0 to 6 in the studied cases and negatively correlated with outcome (rS = -0.98; p = 0.03). CONCLUSION The mortality of GS in Egypt is very high, mainly due to sepsis and prematurity. Young maternal age and poor socioeconomic status are linked to GS. The GPS is a good indicator of morbidity and mortality in a LMIC setting. Survival improved with better resuscitation and strict management protocols. More effort is needed to improve antenatal detection, and transfer time should be ideally below 8 h. LEVEL OF EVIDENCE Level IV.

Abstract
Non-invasive evaluation of renal transplant function is essential to minimize and manage renal rejection. A computer-assisted diagnostic (CAD) system was developed to evaluate kidney function post-transplantation. The developed CAD system utilizes the amount of blood-oxygenation extracted from 3D (2D + time) blood oxygen level-dependent magnetic resonance imaging (BOLD-MRI) to estimate renal function. BOLD-MRI scans were acquired at five different echo-times (2, 7, 12, 17, and 22) ms from 15 transplant patients. The developed CAD system first segments kidneys using the level-sets method followed by estimation of the amount of deoxyhemoglobin, also known as apparent relaxation rate (R2*). These R2* estimates were used as discriminatory features (global features (mean R2*) and local features (pixel-wise R2*)) to train and test state-of-the-art machine learning classifiers to differentiate between non-rejection (NR) and acute renal rejection. Using a leave-one-out cross-validation approach along with an artificial neural network (ANN) classifier, the CAD system demonstrated 93.3% accuracy, 100% sensitivity, and 90% specificity in distinguishing AR from non-rejection . These preliminary results demonstrate the efficacy of the CAD system to detect renal allograft status non-invasively.

Abstract
BACKGROUND Argonaute-2 (Ago2) is an essential component of microRNA biogenesis implicated in tumourigenesis. However Ago2 expression and localisation in breast cancer remains undetermined. The aim was to define Ago2 expression (mRNA and protein) and localisation in breast cancer, and investigate associations with clinicopathological details. METHODS Ago2 protein was stained in breast cancer cell lines and tissue microarrays (TMAs), with intensity and localization assessed. Staining intensity was correlated with clinicopathological details. Using independent databases, Ago2 mRNA expression and gene alterations in breast cancer were investigated. RESULTS In the breast cancer TMAs, 4 distinct staining intensities were observed (Negative, Weak, Moderate, Strong), with 64.2% of samples stained weak or negatively for Ago2 protein. An association was found between strong Ago2 staining and, the Her2 positive or basal subtypes, and between Ago2 intensity and receptor status (Estrogen or Progesterone). In tumours Ago2 mRNA expression correlated with reduced relapse free survival. Conversely, Ago2 mRNA was expressed significantly lower in SK-BR-3 (HER2 positive) and BT-20 (Basal/Triple negative) cell lines. Interestingly, high levels of Ago2 gene amplification (10-27%) were observed in breast cancer across multiple patient datasets. Importantly, knowledge of Ago2 expression improves predictions of breast cancer subtype by 20%, ER status by 15.7% and PR status by 17.5%. CONCLUSIONS Quantification of Ago2 improves the stratification of breast cancer and suggests a differential role for Ago2 in breast cancer subtypes, based on levels and cellular localisation. Further investigation of the mechanisms affecting Ago2 dysregulation will reveal insights into the molecular differences underpinning breast cancer subtypes.

Abstract
OBJECTIVE The aim was to analyse the incidence and presentation of carotid patch inflammatory reactions following carotid endarterectomy (CEA). METHODS This was a cohort study using a prospectively maintained database. All patients who underwent elective CEA at a tertiary vascular centre between 2002 and 2016 were included. Computed tomography scan angiogram, duplex scan, and leucocyte scintigraphy were used to assess patients with suspected inflammatory patch complications. Re-intervention procedures and outcomes were noted. Histopathology and organisms cultured from the harvested material during re-intervention were assessed. RESULTS During the study period, 633 patients underwent elective CEA. Fifty-one underwent eversion endarterectomy: 111 did not require a patch, whereas 471 patients had a patch repair. Four hundred and twenty eight had a Dacron patch repair and 43 a biological patch. Eight patients returned with late Dacron patch inflammatory complications (1.3% of all CEA and 1.9% of Dacron patch closures) after a period ranging from 18 months to 7 years (mean 4.1 ± 2.1 years). Seven of the eight patients underwent surgical re-intervention, and the eighth patient was deemed high surgical risk. One patient underwent a vein bypass, three had vein patch repair, one required internal carotid artery (ICA) ligation after patch excision, and two were managed by debridement, with omohyoid and sternomastoid muscle covering of the patch. The patient who required ICA ligation suffered a fatal stroke. The remaining patients had a satisfactory outcome. All patients showed evidence of foreign body reaction in pathological examination with no pathological organism cultured from swabs or tissue harvested during surgery. CONCLUSION Late wound complications after CEA may be related to inflammatory reaction of the Dacron patch rather than infection. Infection should be excluded first. Reconstruction with vein is effective. However, debridement with sternomastoid and omohyoid muscle covering of the patch may be considered in high risk patients after exclusion of infection with regular follow-up.

Abstract
Several recent studies have indicated the possible association between exposure to particulate air pollution and the increased rate of morbidity and mortality in patients with kidney diseases. The link of this observation to vascular damage has not been adequately addressed. Therefore, this study aims to investigate possible vascular damage that might be associated with exposure to diesel exhaust particles (DP) in adenine (AD)-induced chronic kidney disease (CKD) in rats, and the possible ameliorative effect of gum acacia (GA). CKD was induced by feeding AD (0.75%, w/w), and DP (0.5 mg/kg) was instilled intratracheally every second day and GA was given concomitantly in the drinking water at a dose of 15% w/v. All treatments were given concomitantly for 28 days. Changes in renal blood flow (RBF) and systolic and diastolic blood pressure were monitored in these animals after anesthesia, together with several other endpoints. Exposure to DP significantly reduced RBF and this was significantly potentiated in AD-treated rats. Phenylephrine-induced decreases in RBF and increases in systolic and diastolic blood pressure were severely potentiated in rats exposed to DP, and these actions were significantly augmented in AD-treated rats. GA did not significantly affect the vascular impairment induced by AD and DP given together. This study provides experimental evidence that exposure to particulate air pollution can exacerbate the vascular damage seen in patients with CKD. © 2016 Wiley Periodicals, Inc.

Abstract
PURPOSE To assess incidence and natural history of umbilical hernia following sutured and sutureless gastroschisis closure. METHODS With audit approval, we undertook a retrospective clinical record review of all gastroschisis closures in our institution (2007-2013). Patient demographics, gastroschisis closure method and umbilical hernia occurrence were recorded. Data, presented as median (range), underwent appropriate statistical analysis. RESULTS Fifty-three patients were identified, gestation 36 weeks (31-38), birth weight 2.39 kg (1-3.52) and 23 (43 %) were male. Fourteen patients (26 %) underwent sutureless closure: 12 primary, 2 staged; and 39 (74 %) sutured closure: 19 primary, 20 staged. Sutured closure was interrupted sutures in 24 patients, 11 pursestring and 4 not specified. Fifty patients were followed-up over 53 months (10-101) and 22 (44 %) developed umbilical hernias. There was a significantly greater hernia incidence following sutureless closure (p = 0.0002). In sutured closure, pursestring technique had the highest hernia rate (64 %). Seven patients underwent operative hernia closure; three secondary to another procedure. Seven patients had their hernias resolve. One patient was lost to follow-up and seven remain under observation with no reported complications. CONCLUSIONS There is a significant umbilical hernia incidence following sutureless and pursestring sutured gastroschisis closure. This has not led to complications and the majority have not undergone repair.

Abstract
UNLABELLED A β3 adrenoceptor agonist plays an important regulatory role in stimulation of thermogenesis and lipolysis and it appears to have anti-ulcer and spasmolytic effects. So the present aim was to examine the effect of BRL 37344 (a selective B3 adrenoceptor agonist) on reflux esophagitis. METHODS Forty-eight rats were divided into twelve sham-operated with BRL 37344 and/or omeprazole with or without indomethacin. RE was induced in rats, then gastric acid output, pH, plasma nitric oxide (NO), esophageal PGE2, malondialdehyde (MDA) and reduced glutathione (GSH) were measured and the esophageal injury was assessed by macroscopic damage score. RESULTS Pretreatment with BRL significantly increased plasma NO, GSH, decreased acid output, esophageal MDA and esophageal injury in comparison to pretreatment. In addition, there was a no significant increase in esophageal PGE2. CONCLUSION It can be concluded that BRL 37344 has an anti-oxidant protective effect in rats with RE.

Abstract
UNLABELLED Biliary atresia (BA) is characterized by a variable degree of fibrosis within the liver, causing portal hypertension sometimes evident at the time of presentation. AIM The aims of this study are to measure portal venous pressure (PVP) at time of Kasai portoenterostomy (KP) and to investigate the value of surrogate indices. METHODS At the time of KP and before any liver manipulation, an attempt was made to recanalize the umbilical vein, allowing a catheter to be sited. Preoperative noninvasive variables included maximum splenic diameter (on ultrasound); platelet count, aspartate aminotransferase, and bilirubin; and the aspartate aminotransferase/platelet index ratio (APRi). Clearance of jaundice was defined as achieving a bilirubin of less than 20 μmol/L. Data are quoted as median (range). Nonparametric statistical tests were used, and P < .05 was regarded as significant. RESULTS Portal venous pressure measurements were available in 61 infants, who underwent a KP during the period February 2007 to October 2010. Median age at KP was 52 (19-151) days. Median PVP was 9 (3-26) mm Hg and was significantly lower in those with isolated (n = 47) BA vs cytomegalovirus-associated BA (n = 6) (8 vs 17 mm Hg; P = .02). Overall, PVP correlated with spleen size (r(s) = 0.38; P < .0001), APRi (r(s) = 0.5; P < .0001), bilirubin (r(s) = 0.38; P = .001), and age at KP (r(s) = 0.33; P = .0004). Thirty-three infants (56%) cleared their jaundice (to <20 μmol/L). There was no significant difference in median PVP (7 vs 9.5 mm Hg; P = .1) between these groups. To date, 6 children have undergone endoscopy, with 2 requiring intervention for significant varices. Neither infant at time of KP had elevated PVP (3 and 9 mm Hg). CONCLUSIONS Portal venous pressure is a key variable in the assessment of the BA liver, and differences can be shown depending on underlying cause (eg, cytomegalovirus status). Furthermore, it has modest correlation with noninvasive indices (eg, spleen size and APRi) but appears of limited use when used as prognostic index of outcome and indeed in the later development of varices.

Abstract
Chordomas are radio- and chemo-resistant tumours and metastasise in as many as 40% of patients. The aim of this study was to identify potential molecular targets for the treatment of chordoma. In view of the reported association of chordoma and tuberous sclerosis complex syndrome, and the available therapeutic agents against molecules in the PI3K/AKT/TSC1/TSC2/mTOR pathway, a tissue microarray of 50 chordoma cases was analysed for expression of active molecules involved in this signalling pathway by immunohistochemistry and a selected number by western blot analysis. Chordomas were positive for p-AKT (92%), p-TSC2 (96%), p-mTOR (27%), total mTOR (75%), p-p70S6K (62%), p-RPS6 (22%), p-4E-BP1 (96%) and eIF-4E (98%). Phosphatase and tensin homologue deleted on chromosome 10 expression was lost in 16% of cases. Mutations failed to be identified in PI3KCA and RHEB1 in the 23 cases for which genomic DNA was available. Fluorescence in situ hybridisation analysis for mTOR and RPS6 loci showed that 11 of 33 and 21 of 44 tumours had loss of one copy of the respective genes, results which correlated with the loss of the relevant total proteins. Fluorescence in situ hybridisation analysis for loci containing TSC1 and TSC2 revealed that all cases analysed harboured two copies of the respective genes. On the basis of p-mTOR and or p-p70S6K expression there is evidence indicating that 65% of the chordomas studied may be responsive to mTOR inhibitors, rapamycin or its analogues, and that patients may benefit from combined therapy including drugs that inhibit AKT.

Abstract
A battery of Arabic speech material was developed for remediation of selective auditory attention disorder (SAAD) in children and standardized on 40 normal children aged from 6 to 12 years. This battery included: the Word Intelligibility by Picture Identification (WIPI) test, newly developed sentences for speech discrimination in noise, bisyllabic words and monosyllabic words. The tests were recorded against a background noise of either multitalker babble or stories. Variables affecting the results of the new battery, namely age, type of speech material and type of background noise, were studied. A significant positive correlation was found between the age of the child and the test scores. The WIPI test was the easiest test, giving the highest scores. The monosyllabic words test was the most difficult, yet normal children gave mean scores around 92%. The type of background noise showed a non-significant effect on the test scores. Results of two cases with SAAD are also presented.
