Abstract
OBJECTIVE Urinary incontinence is defined as involuntary loss of urine, a common health condition that is more frequent in women. It disturbs the affected individuals and interferes with their daily activities. This study aimed to estimate the prevalence of urinary incontinence among Saudi women in the western area of the Kingdom of Saudi Arabia. SUBJECTS AND METHODS A descriptive cross-sectional design was used for this study. A survey was administered to Saudi women in the western area of the Kingdom of Saudi Arabia ranging in age from 18 to 70 years. The data were collected using the Arabic version of the Questionnaire for Urinary Incontinence Diagnosis. Descriptive statistics were generated by calculating numbers and percentages of information on the prevalence of incontinence in women. p-values < 0.05 were considered statistically significant. RESULTS The prevalence of urinary incontinence was 44.2%, with the urge type being the most reported. Stress urinary incontinence was reported by 155 women (15.4%), urgency urinary incontinence by 257 women (25.6%), and mixed urinary incontinence by 102 women (10.15%). CONCLUSIONS Urinary incontinence is prevalent in women in Western Saudi Arabia. Age, multiparty obesity, and vaginal surgery are significant risk factors influencing its occurrence.

Abstract
OBJECTIVE In the hospital setting, long waiting times and the lengthy formal process have increased the inefficiency and mismanagement resulting in the missing chance of saving the patients' life. Our aim was to assess the time wastage of every patient coming from reception to the actual emergency unit, to analyze the factor associated with the time lapse that occurs during every visit, and to see the effect of training on the services provided in the Pediatric emergency room. SUBJECTS AND METHODS An intervention study was carried out in the following secondary care hospital in the Al Jouf region, Saudi Arabia: Esawiyah Hospital, Haditha Hospital, King Faisal Hospital, and Gurayat General Hospital among 400 study participants for 12 months. The study was carried out in 2 phases: pre-training, a period of training for hospital staff, and post-training data collection. Templates were generated on an MS Excel sheet and analysis of data was done using SPSS software. Percentages and proportions were calculated for descriptive statistics. RESULTS Male and female patients were in the ratio of nearly 1:1. Training has significantly reduced the time to doctor consultation (U = 188, p < 0.001), and the time difference pre- and post-training from triage to consultation in a pediatric emergency is not significant (U = 16,769, p = 0.01). There is a strongly significant association (p < 0.001) between Canadian Triage and Acuity Scale (CTAS) implementation in triage. The practice of giving intravenous (IV) antibiotics in the emergency room has reduced significantly (p < 0.001) post-training. CONCLUSIONS Training has a significant impact on the services provided in the pediatric emergency room.

Abstract
OBJECTIVE This study aimed at assessing asthma control test (ACT score), quality of life (QOL), and pulmonary functions in asthmatic children, and to see the correlations between ACT score, QOL, and pulmonary functions. PATIENTS AND METHODS This cross-sectional study was conducted at the departments of pediatrics and physiology, College of Medicine, King Saud University Medical City (KSUMC), Riyadh, Saudi Arabia. A total of 109 (53 asthmatics and 56 controls) children (aged 6 to 13 years) of both genders were studied. All subjects underwent clinical evaluation, 36-Item Short Form Survey (SF-36) for QOL, Spirometry, and cognitive assessment through mini mental state examination (MMSE). RESULTS QOL showed significantly lower scores in asthmatic compared to non-asthmatic children. The higher social functioning [SF] (p=0.0012) and less role limitation due to physical health [RLPH] (non-asthmatic patients had had higher physical functioning [PF] (p=0.0001), less energy/fatigue [EF] (p=0.0008=0.0068). On the opposite side, no significant difference was found regarding role limitations due to emotional problems [RLEP] (p=0.0644) and Emotional well-being [EW] (p=0.0758) between the two groups. A significant positive correlation was seen between QOL items and ACT score in PF (r=.535, p<0.01), less RLPH (r=.593, p<0.01), less FE (r=.379, p<0.01), higher EW (r=.310, p<0.05), and higher SF (r=.495, p<0.01). No significant correlation was found between body mass index (BMI) and lung functions in children with asthma. Interestingly, a positive correlation was found in asthmatic children between BMI and MMSE scores (r=.298, p=0.030). CONCLUSIONS Our study concluded that QOL in asthmatic patients was significantly lower than healthy subjects in terms of patient's physical functioning and social life. However, the emotional aspects of QOL were not significantly affected in asthmatic children.

Abstract
Aims Cardiac magnetic resonance (CMR) was used to assess whether cardiac function or tissue composition was affected in patients with well-functioning metal-on-metal hip resurfacing arthroplasties (MoMHRA) when compared with a group of controls, and to assess if metal ion levels correlated with any of the functional or structural parameters studied. Patients and Methods In all, 30 participants with no significant cardiac history were enrolled: 20 patients with well-functioning MoMHRA at mean follow-up of 8.3 years post-procedure (ten unilateral, ten bilateral; 17 men, three women) and a case-matched control group of ten non-MoM total hip arthroplasty patients (six men, four women). The mean age of the whole cohort (study group and controls) at the time of surgery was 50.6 years (41.0 to 64.0). Serum levels of cobalt and chromium were measured, and all patients underwent CMR imaging, including cine, T2* measurements, T1 and T2 mapping, late gadolinium enhancement, and strain measurements. Results None of the MoMHRA patients showed clinically significant cardiac functional abnormality. The MoMHRA patients had larger indexed right and left end diastolic volumes (left ventricular (LV): 74 ml/m2 vs 67 ml/m2, p = 0.045; right ventricular: 80 ml/m2 vs 71 ml/m2, p = 0.02). There was a small decrease in T2 time in the MoMHRA patients (median 49 ms vs 54 ms; p = 0.0003). Higher metal ion levels were associated with larger LV volumes and with shorter T2 time. Conclusion Although cardiac function is not clinically adversely affected in patients with well-functioning MoMHRA, modern imaging is able to demonstrate subtle changes in structure and function of the heart. As these changes correlate with systemic ion measurements, they may be consequences of wear debris deposition. Longer, longitudinal studies are necessary to determine whether cardiac function will become affected. Cite this article: Bone Joint J 2019;101-B:540–546.

Abstract
The purpose of this study was to investigate whether growth factors produced by activated human lung mast cells (HLMCs) impair β2 -adrenoceptor (β2 -AR) function in human airway smooth muscle (ASM) cells. Protein array analysis confirmed the presence of various growth factors, including transforming growth factor (TGF)-β1, in the supernatants of high-affinity IgE receptor (FcεRI)-activated HLMCs which, when applied to ASM cells, impaired albuterol-induced cyclic adenosine monophosphate (cAMP) production, an effect that was prevented following neutralization of TGF-β1. This blunted β2 -AR response was reproduced by treating ASM cells with TGF-β1 or fibroblast growth factor (FGF)-2, which induced β2 -AR phosphorylation at tyrosine residues Tyr141 and Tyr350 , and significantly reduced the maximal bronchorelaxant responses to isoproterenol in human precision cut lung slices (PCLS). Finally, ASM cells isolated from severe asthmatics displayed constitutive elevated β2 -AR phosphorylation at both Tyr141 and Tyr350 and a reduced relaxant response to albuterol. This study shows for the first time that abnormal β2 -AR phosphorylation/function in ASM cells that is induced rapidly by HLMC-derived growth factors, is present constitutively in cells from severe asthmatics.

Abstract
OBJECTIVES As of 1 November 2015, the Saudi Ministry of Health had reported 1273 cases of Middle East respiratory syndrome (MERS); among these cases, which included 9 outbreaks at several hospitals, 717 (56%) patients recovered, 14 (1%) remain hospitalised and 543 (43%) died. This study aimed to determine the epidemiological, demographic and clinical characteristics that distinguished cases of MERS contracted during outbreaks from those contracted sporadically (ie, non-outbreak) between 2012 and 2015 in Saudi Arabia. DESIGN Data from the Saudi Ministry of Health of confirmed outbreak and non-outbreak cases of MERS coronavirus (CoV) infections from September 2012 through October 2015 were abstracted and analysed. Univariate and descriptive statistical analyses were conducted, and the time between disease onset and confirmation, onset and notification and onset and death were examined. RESULTS A total of 1250 patients (aged 0-109 years; mean, 50.825 years) were reported infected with MERS-CoV. Approximately two-thirds of all MERS cases were diagnosed in men for outbreak and non-outbreak cases. Healthcare workers comprised 22% of all MERS cases for outbreak and non-outbreak cases. Nosocomial infections comprised one-third of all Saudi MERS cases; however, nosocomial infections occurred more frequently in outbreak than non-outbreak cases (p<0.001). Patients contracting MERS during an outbreak were significantly more likely to die of MERS (p<0.001). CONCLUSIONS To date, nosocomial infections have fuelled MERS outbreaks. Given that the Kingdom of Saudi Arabia is a worldwide religious travel destination, localised outbreaks may have massive global implications and effective outbreak preventive measures are needed.

Abstract
BACKGROUND The mechanisms driving glucocorticoid (GC) insensitivity in patients with severe asthma are still unknown. Recent evidence suggests the existence of GC-insensitive pathways in airway smooth muscle (ASM) caused by a defect in GC receptor (GRα) function. We examined whether other mechanisms could potentially explain the reduced sensitivity of ASM cells to GC in severe asthmatics. METHODS Airway smooth muscle cells from healthy and severe asthmatic subjects were treated with TNF-α and responses to corticosteroids in both cohorts were compared by ELISA, immunoblot, immunohistochemistry and real-time PCR. Immunohistochemistry and flow cytometry assays were used to assess the expression of the protein phosphatase PP5 in endobronchial biopsies and ASM cells. RESULTS The production of CCL11 and CCL5 by TNF-α was insensitive to both fluticasone and dexamethasone in ASM cells from severe asthmatic compared to that in healthy subjects. Fluticasone-induced GRα nuclear translocation, phosphorylation at serine 211 and expression of GC-induced leucine zipper (GILZ) were significantly reduced in ASM cells from severe asthmatics compared to responses in healthy subjects. Levels of PP5 were increased in ASM cells from severe asthmatics and PP5 knockdown using siRNA restored fluticasone repressive action on chemokine production and its ability to induce GRα nuclear translocation and GRE-dependent GILZ expression. In vivo PP5 expression was also increased in the ASM bundles in endobronchial biopsies in severe asthmatics. CONCLUSIONS PP5-dependent impairment of GRα function represents a novel mechanism driving GC insensitivity in ASM in severe asthma.

Abstract
INTRODUCTION Primary tethered spinal cord (TSC) refers to a group of abnormalities associated with a posterior bony spinal defect that develops beneath an intact dermis and epidermis. There is relative agreement that patients with symptomatic TSC will require surgical intervention. However, it is still debatable as to how to approach asymptomatic patients with primary TSC. OBJECTIVE To study the clinical and urodynamic (UDS) outcomes of patients with primary TSC after spinal cord untethering (SCU). STUDY DESIGN Charts of patients with primary TSC between 1998 and 2010 were retrospectively reviewed. Patients that underwent before and after SCU clinical and UDS evaluation with minimum of 5-years follow-up were included. Continence status was assessed in children ≥5 years. Patients with dry intervals of ≥4 h were considered continent. Urologic and neuro-orthopedic manifestations, as well as UDS parameters, were compared before and after SCU. Categorical data were compared using Fisher-Exact test and continuous variables were compared using Wilcoxon-Signed-Rank test. A P-value <0.05 was considered significant. RESULTS Twenty-two patients met the inclusion criteria. The median age at time of SCU was 11.5 months (range 3-211). The median age at time of follow-up UDS after SCU was 22 months (range 9-218). The median age at time of last follow-up was 153.5 months (range 65-228). The median follow-up time was 71 months (range 60-192). A total of 14/22 patients had clinical manifestation before SCU, while 8/22 were asymptomatic and diagnosed based on magnetic resonance imaging/UDS findings. Of the symptomatic patients, 86% had symptom improvement after SCU. The UDS parameters showed statistically significant improvement in the median percentage of change of actual bladder capacity (P = 0.01), median intravesical pressure for patients with pre-operative pressure ≥40 cm/H2O at total cystometric bladder capacity (P = 0.012), and median bladder compliance at 75% bladder capacity (P = 0.01) (Table). DISCUSSION Tethered spinal cord syndrome (TSCS) is a clinical entity that presents with neurological, urological, and/or orthopedic symptoms caused by primary or secondary tethering of the spinal cord, which may result in ischemic damage of the neural tissue and symptom development. While some authors believe that surgical management should be reserved for symptomatic patients, others prefer prophylactic surgery to avoid possible irreversible neurological damage. The present study provides detailed discussion of the clinical and UDS outcomes for patients with primary TSC that underwent SCU. CONCLUSION For patients with primary TSC, spinal cord untethering is beneficial in terms of clinical and UDS outcomes. A prospective long-term study with large numbers could further highlight outcomes for this particular group of patients.

Abstract
BACKGROUND To investigate the association between preoperative pathological Ki67 labeling index and serum tumor marker cancer antigen 153 (CA 153) with clinicpathological parameters and treatment outcomes in early breast cancer. MATERIALS AND METHODS A retrospective study at 4 cancer centers in Saudi Arabia and Egypt was performed. Data were collected for female patients diagnosed with unilateral early breast cancer between March 2010 and October 2013. Cases treated with neoadjuvant chemotherapy (NACT) followed by surgery and radiotherapy were included. NACT included 68 cycles of anthracycline and taxane based regimens. Trastuzumab and hormonal treatments were added according to HER2 and hormone receptor status. Baseline serum CA15.3 and pathological Ki67 levels were evaluated and correlated with disease free survival (DFS) and overall survival (OS). RESULTS A total of 280 pts was included. The median age was 49 years (3866 y) and median overall survival was 35 (2038) months (mo). Estrogen receptors (ER), progesterone receptors (PR) and HER 2 receptors were positive in 233 (83.2%), 198 (70%) and 65 cases (23.2%), respectively. High preoperative Ki67 and CA15.3 were noted in 177 (63.2%) and 131 (46.8%). A total of 45 (16%) patients had distal or local recurrence and 24 (8.6%) died of their disease. Most of the relapsed cases had high preoperative Ki67 (n=41, 91%) and CA15.3 (n=28, 62%) values. All of the patients who died had a high Ki67 but CA15.3 was high in 9 (37%) only. Mean DFS/OS in patients with high preoperative Ki67 was 32 months /32 months as compared to 37 months/35 months in those with normal Ki67 (p<0.001). Correlation of preoperative CA15.3 and survival was statistically not significant. CONCLUSIONS Preoperative Ki67 can be a predictive and prognostic marker. Higher levels are associated with poor DFS and OS in patients with early BC.

Abstract
PURPOSE This study aimed to explore the association of β-catenin expression pattern with pathological response after neoadjuvant chemotherapy in breast cancer (BC) patients. MATERIALS AND METHODS In this retrospective exploratory study, data for 50 BC patients who received neoadjuvant chemotherapy were recorded. β-catenin expression in tumours was assessed using immunohistochemistry and classified as either membranous or cytoplasmic according to the pattern of staining. Distributions of different clinico-pathological parameters according to β-catenin expression were assessed using the Chi-square test. Logistic regression analysis was used to assess any relation of the pattern of β-catenin expression with the pathological response. RESULTS Cytoplasmic β-catenin expression was detected in 34% of BCs. Among our cases, 52% were hormonal receptor (HR)-positive, 24% were HER2-positive, 74% were clinical stage III and 74% received both anthracycline and taxane-based chemotherapy. Patients with cytoplasmic expression were more commonly younger than 40 years at diagnosis (cytoplasmic, 41.2% vs. no cytoplasmic expression, 12.1%, p=0.03). By doing t-test, cytoplasmic β-catenin expression was linked with a higher body mass index compared to membranous-only expression (mean± SD 33.0 ± 4.47 vs. 29.6 ±6.01, respectively, p=0.046). No significant associations were found between β-catenin expression and other parameters such as HR and HER2 status, or clinical stage. Complete pathological response (pCR) rate was twice as great in patients with membranous expression but without statistical signi cance (membranous- only, 33.3% vs. cytoplasmic, 17.6%, OR=2.3, 95% CI= 0.55-9.87, p=0.24). CONCLUSIONS This study suggests that cytoplasmic β-catenin expression may be linked with lower probability of achieving pCR after neoadjuvant chemotherapy. These data need to be validated in a larger cohort of patients.

Abstract
BACKGROUND This study aims to evaluate the relation between mammographic breast density (BD) and pathological response to neoadjuvant chemotherapy. METHODS In this retrospective study, 241 breast cancer patients who received neoadjuvant chemotherapy were included. BD was assessed in mammograms already performed at diagnosis. Pathological complete response (pCR) and pathological stage were correlated with BD, tumour phenotype and other clinico-pathological factors. RESULTS Patients with low BD had better pCR compared to those with high density (30.5% vs 19.5% respectively, OR = 1.8, 95% CI = 0.98-3.3, p = 0.056) which was more pronounced after adjustment with body mass index (BMI) (OR = 2.4, 95% CI = 1.2-4.8, p = 0.011). HER2-positive disease (32.5% vs. 18.4%, OR = 2.2, 95% = 1.2-4.0, p = 0.01), lower BMI (OR = 1.1, 95% CI = 1.03-1.15, p = 0.004) and lower clinical stage (p = 0.002) were significant predictors of pCR in univariate analysis. In multivariate analysis, low BD (OR = 2.7, 95% CI = 1.3-5.5, p = 0.006) and lower BMI (OR = 1.1, 95% CI = 1.03-1.17, p = 0.003) were independent predictors of better pCR, while early clinical stage (I, II) was of borderline significance (OR = 2.6, 95% CI = 0.99-6.7, p = 0.052). High BD (OR = 1.8, 95% CI = 1.1-3.2, p = 0.03), advanced clinical stage (III) (OR = 1.5, 95% CI = 1.03-2.1, p = 0.03) and higher BMI (OR = 1.06, 95% CI = 1.02-1.11, p = 0.006) were significant predictors of advanced pathological stage. CONCLUSION Low mammographic BD, low BMI and early clinical stage were associated with improved pCR rate and lower pathological stage after neoadjuvant chemotherapy. BD had more pronounced association with response to chemotherapy after adjustment with BMI.

Abstract
In an attempt to find genes that may be of importance in malignant progression of papillary thyroid carcinoma (PTC) in the Middle East, which therefore can be targeted in cancer therapy, we screened and validated the global gene expression in PTC using cDNA expression arrays and immunohistochemistry (IHC) on tumour tissue microarrays. Twenty-nine PTC tissue specimens were compared with seven non-cancerous thyroid specimens by use of cDNA microarray. Results for selected genes were confirmed by quantitative real-time PCR. Protein expression of selected genes was further studied using a tissue microarray consisting of 536 PTCs and compared with histologically non-cancerous tissue samples. One hundred and ninety-six genes were overexpressed in PTC tissues relative to non-cancerous thyroid tissues. The genes that were up-regulated in PTC were involved in cell cycle regulation, cell signaling, and oncogenesis. Among these genes, c-MET was identified by immunohistochemical methods as a protein that is overexpressed in 37% of PTCs and was significantly associated with more aggressive behaviour, eg higher stage, nodal involvement, and tall cell variant (p value = 0.01, 0.01 and 0.04, respectively). In this study, 55% of the PTC cases expressed activated AKT (P-AKT), which suggests that activated AKT may play an important role in PTC tumourigenesis. The fact that most of the PTC cases that had activated AKT showed overexpression of c-MET (p = 0.027) leads us to hypothesize that c-MET may be an alternative mechanism of AKT activation in Middle Eastern PTCs. Finally, our data suggest that c-MET dysregulation is associated with aggressive behaviour and may serve as a molecular biomarker and potential therapeutic target in this disease.

Abstract
OBJECTIVE We report on 3 patients who underwent laparoscopic antireflux procedures for persistent symptoms of GERD after biopolymer injection. METHODS Experienced laparoscopic surgeons completed all 3 procedures laparoscopically. In 2 patients, there was an extramural extravasation of the polymer outside and adherent to the esophageal wall. In these patients, a partial posterior fundoplication was used. The third patient, who had the polymer material deposits removed preoperatively by endoscopic mucosal resection, underwent a Nissen fundoplication. RESULTS Postoperative recovery was uneventful in all cases. At follow-up of 6 to 12 months, all patients were symptom free, off medical therapy, and experiencing no dysphagia. CONCLUSION Surgical therapy for patients after failed biopolymer injection is safe and effective. The choice of surgery may depend on whether the polymer mass can be removed preoperatively.
