OBJECTIVE Resection of meningiomas in direct contact with the anterior optic apparatus carries risk of injury to the visual pathway. Stereotactic radiosurgery (SRS) offers a minimally invasive alternative. However, its use is limited owing to the risk of radiation-induced optic neuropathy. Few SRS studies have specifically assessed the risks and benefits of treating meningiomas in direct contact with the optic nerve, chiasm, or optic tract. The authors hypothesized that SRS is safe for select patients with meningiomas in direct contact with the anterior optic apparatus. METHODS The authors performed an international multicenter retrospective analysis of 328 patients across 11 institutions. All patients had meningiomas in direct contract with the optic apparatus. Patients were followed for a median duration of 56 months after SRS. Neurological examinations, including visual function evaluations, were performed at follow-up visits. Clinical and treatment variables were collected at each site according to protocol. Tumor volumes were assessed with serial MR imaging. Variables predictive of visual deficit were identified using univariable and multivariable logistic regression. RESULTS SRS was the initial treatment modality for 64.6% of patients, and 93% of patients received SRS as a single fraction. Visual information was available for 302 patients. Of these patients, visual decline occurred in 29 patients (9.6%), of whom 12 (41.4%) had evidence of tumor progression. Visual decline in the remaining 17 patients (5.6%) was not associated with tumor progression. Pre-SRS Karnofsky Performance Status predicted visual decline in adjusted analysis (adjusted OR 0.9, 95% CI 0.9–1.0, p < 0.01). Follow-up imaging data were available for 322 patients. Of these patients, 294 patients (91.3%) had radiographic evidence of stability or tumor regression at last follow up. Symptom duration was associated with tumor progression in adjusted analysis (adjusted OR 1.01, adjusted 95% CI 1.0–1.02, adjusted p = 0.02). CONCLUSIONS In this international multicenter study, the vast majority of patients exhibited tumor control and preservation of visual function when SRS was used to treat meningioma in direct contact with the anterior optic pathways. SRS is a relatively safe treatment modality for select patients with perioptic meningiomas in direct contact with the optic apparatus.

Aims/Introduction To study the epidemiology, genetic landscape and causes of childhood diabetes mellitus in the State of Qatar. Materials and methods All patients (aged 0–18 years) with diabetes mellitus underwent biochemical, immunological and genetic testing. American Diabetes Association guidelines were used to classify types of diabetes mellitus. The incidence and prevalence of all the different types of diabetes mellitus were calculated. Results Total number of children with diabetes mellitus was 1,325 (type 1 n = 1,096, ≥1 antibody; type 2 n = 104, type 1B n = 53; maturity onset diabetes of the young n = 20; monogenic autoimmune n = 4; neonatal diabetes mellitus n = 10;, syndromic diabetes mellitus n = 23; and double diabetes mellitus n = 15). The incidence and prevalence of type 1 diabetes were 38.05 and 249.73 per 100,000, respectively, and for type 2 were 2.51 and 23.7 per 100,000, respectively. The incidence of neonatal diabetes mellitus was 34.4 per 1,000,000 live births, and in indigenous Qataris the incidence was 43.6 per 1,000,000 live births. The prevalence of type 1 diabetes and type 2 diabetes in Qatari children was double compared with other nationalities. The prevalence of maturity onset diabetes of the young in Qatar was 4.56 per 100,000. Conclusions This is the first prospective and comprehensive study to document the epidemiology and genetic landscape of childhood diabetes mellitus in this region. Qatar has the fourth highest incidence of type 1 diabetes mellitus, with the incidence and prevalence being higher in Qatari compared with non‐Qatari. The prevalence of type 2 diabetes mellitus is also higher in Qatar than in Western countries. The incidence of neonatal diabetes mellitus is the second highest in the world. GCK is the most common form of maturity onset diabetes of the young, and a large number of patients have type 1B diabetes mellitus., This is the first comprehensive, prospective study from the Middle East North Africa region to systematically study the causes of diabetes in every child in the State of Qatar. The State of Qatar has the fourth highest incidence of type 1 diabetes in the world. The incidence of type 2 diabetes is much higher in Qatar than in Western countries. Both type 1 and type 2 diabetes are more common in the Qatari population than the non‐Qatari population. Mutations in GCK were the most common cause of maturity onset diabetes of the young, and mutations in the PTF1A and INS genes were the most common cause of neonatal diabetes in this population.

Objectives Children with antibody positive type 1 diabetes mellitus (type 1 diabetes) are at an increased risk of developing celiac disease (CD) which suggests a common autoimmune basis with both high-risk human lymphocyte antigen (HLA) and non-HLA factors playing a role in the pathophysiology. We aim to describe the prevalence, immune profile, and clinical characteristics of children with CD who have type 1 diabetes mellitus in Qatar. Methods All children (aged 0–18 years) attending a regional diabetes clinic with antibody positive type 1 diabetes were screened for CD. Measurement of tissue transglutaminase IgA and IgG as well as anti-endomysial antibody, was done, clinical details about the birth history, family history of diabetes and CD, age of onset, and ethnicity were collected. Results Out of the 1,325 children with antibody positive type 1 diabetes, 54 were identified to have CD on screening and then confirmed on small bowel biopsy. The prevalence of CD in the type 1 diabetes childhood population in Qatar is 4.07%. CD and type 1 diabetes were more prevalent in the Qatari children (n=32) as compared to non-Qatari (n=22) and occurred mostly in the age group 6–10 years. The most common type 1 diabetes antibodies in children with CD were glutamic acid decarboxylase and insulin autoantibody. Twelve subjects were asymptomatic for CD symptoms and picked up only on screening. Conclusions The prevalence of CD in children with type 1 diabetes in Qatar is comparable to reports from around the world. Many children were asymptomatic and thus routine screening is recommended.

Background A growing body of evidence suggested that uric acid (UA) may contribute in the pathways underlying osteoarthritis (OA) pathogenesis; however, studies that investigated the relationship between UA and OA emerged inconclusive results. The purpose of the study was to explore the association of serum uric acid (sUA) levels with clinical severity, radiological severity of knee osteoarthritis (KOA) based on Kellgren-Lawrence (KL) grading system, and MRI changes in non-gouty patients. Results WOMAC scores: pain, stiffness, function, and total score are significantly higher in H-sUA group than L-sUA group (p = 0.004, p = 0.019, p = 0.018, p = 0.008 respectively). Joint space width (JSW) is significantly narrower in H-sUA group than L-sUA group (p = 0.013). H-sUA group had more frequent KL grade 4 (p < 0.001), osteophytes grade 4 (p < 0.001), focal bone erosion (p < 0.001), bone marrow lesions (p = 0.023), and synovitis (p = 0.011) than L-sUA group. Female KOA patients in H-sUA group had significantly higher pain, stiffness, and function and total WOMAC scores than L-sUA group (p = 0.003, p = 0.015, p = 0.008, p = 0.004), more frequently had KL grade 4 and osteophytes grade 4 (p = 0.003, p < 0.001), significantly narrower JSW (p = 0.016), more frequently show focal bone erosion (p = 0.002), bone marrow lesions (p = 0.019), and synovitis (p = 0.004) than L-sUA group. In regression analysis, female sex (p = 0.035), duration of KOA (p = 0.031), and sUA level (p = 0.025) were associated with KL severity. For female patients with KOA, KL severity is associated with duration of KOA (p = 0.045) and sUA (p = 0.009). Conclusion Higher sUA level is associated with higher clinical severity, higher radiographic KL grades, and more frequent MRI findings in patients with primary KOA patients. Our results also indicated that sUA level was significantly associated with KOA severity in female patients, but not in male patients. More studies are warranted to explore whether the two conditions exist simultaneously or there is a direct causal relationship between the two conditions.

Reaching a postmortem diagnosis of hypothermia is challenging in forensic practice. Therefore, this study was conducted to detect the histopathological, histochemical and biochemical changes that occur in adult albino rats following exposure to induced fatal hypothermia. Twenty-four adult albino rats were divided into the negative control, moderate hypothermia, severe hypothermia and hypoxia groups. Rats in the control group were euthanized when those in the moderate hypothermic group died. Blood samples were collected via heart puncture, and the cerebrum, heart, suprarenal gland, kidney, liver and skeletal muscle were removed to investigate the biochemical, histochemical and histopathological changes. Postmortem assessment depicted significant changes in lipid peroxidation, represented by increased malondialdehyde levels in the studied organs of the rats in hypothermic and hypoxia groups. Histopathological examination of the rats’ organs revealed degeneration and necrosis in the hypothermia and hypoxia groups. Sections taken from the severe hypothermic rats revealed a loss of normal cardiac tissue architecture, necrotic changes in the pyramidal cells in the cerebral cortex, and massive necrosis, mainly in the tubules of the renal cortex and medulla. These findings suggest that histological changes might be used as biochemical markers for postmortem diagnosing of fatal hypothermia, particularly in severe hypothermic conditions. Key points Death by hypothermia is a serious public health problem worldwide. Confirming a diagnosis and determining the cause of death in cases of hypothermia are among the most difficult practices in forensic medicine. Death by hypothermia might be associated with structural abnormalities in various organs. Studies using different tissue staining techniques will enable an overall illustration of the role of histopathological changes in body organs as indicators of hypothermia.

Recently, the integration between healthcare services and new technologies has been enhanced to be very necessary and effective inside digital Hospitals. Digital hospitals include a huge number of healthcare advanced technologies that have special digital and architectural requirement; these requirements cannot be provided in traditional hospitals. Many previous studies and guidelines addressed few numbers of digital hospital’s rooms and their architectural requirements. Hence, in this study, healthcare advanced technologies has been determined for outlining the architectural consideration of digital hospital’s rooms. Accordingly, Robotic Surgery Ward (RSW) has been compared with Traditional Surgery Ward (TSW) for: a) demonstrating the effect of an advanced technology (Robotic technology) on a digital hospital ward and b) helping designers to find out the main architectural and economic principles of designing RSWs besides TSWs. The main findings in this study are: a) outlining the main architectural characteristics of digital hospitals in general and digital hospital’s rooms in specific, b) articulating the main architectural and economic aspects for RSW and robotic surgery rooms, which is different from TSW. As an application of the comparative analyses, possible design alternatives of RSW and TSW has been also proposed and compared.

Objective Approximately 30% of lung cancer patients develop central airway obstruction (CAO) that remarkably shortens survival. There is little data about the benefits of stenting within this heterogeneous patient group. Our objective was to review their overall survival (OS) and their risk of hospitalization versus patients who did not have lesions requiring stent placement. Methods We retrospectively reviewed charts of 171 non-small cell lung cancer (NSCLC) patients who underwent bronchoscopy in the University of Cincinnati Cancer Center from the year 2011 to 2013. Twenty-five patients with advanced lung cancer were evaluated by interventional pulmonology service for endobronchial stent placement for CAO. Eight patients did not require placement of a stent and 17 had obstructive lesions that required stenting by interventional pulmonology. Results Demographical parameters such as age and gender did not have a significant impact on the risk of hospitalization or OS of both groups of patients, however, those whose lesions did not mandate stent placement had significantly lower odds of hospitalization compared to patients with CAO requiring a stent (OR: 15.913, 95% CI: 1.211-209.068, P = 0.0352). Patients with advanced NSCLC and CAO that required stent placement had an OS of 13.9 m [3.9-19.9 m] compared to an OS of 23.9 m for patients with CAO not requiring a stent. We found out that patients with less severe CAO have lower odds of hospitalization and better OS compared to patients with CAO mandating stent placement. Conclusion CAO patients with interventional pulmonology (IP) evaluation and management in addition, may have improved OS suggesting that IP consultation might offer both improvement in quality of life and overall survival to patients with advanced NSCLC and CAO. .

Background: Three-dimensional (3D) visualization systems, also known as heads-up systems, are now available for eye surgery and as with every new device there is need for a specific evaluation. Objectives: The aim of this study was to compare the efficiency, surgical comfort, and safety of a 3D visualization system to a standard binocular microscope (BM) in routine ophthalmologic procedures. Method: After a 4-week training period, a 3D visualization system (Ngenuity, Alcon®) available in one of the Robert Debré Hospital Ophthalmology Departments’ operating rooms was compared to a standard BM (OPMI LUMIRA 700, Zeiss®), in the process of a call for new device evaluation. From December 2017 to March 2018, 5 surgeons and their respective residents were asked to fill in a questionnaire for all procedures. Before the surgery, the surgeon recorded: (i) the type of surgery (cataract [PK], retinal detachment [RD], epiretinal membrane peeling [ERM], macular hole, vitreous haemorrhage [VH]), (ii) the type of visualization system chosen (3D or BM), and (iii) the estimated surgical risk (low, intermediate, or high grade). At the end of the procedure, the primary surgeon recorded the remaining parameters, including: (i) surgery duration, (ii) intraoperative complications, (iii) percentage of endoillumination for posterior segment surgeries, (iv) status of the operator (senior or resident) and operator switch if necessary (senior only, resident only, or resident with help of the senior), and rated: (i) the visual comfort (low, normal, excellent), (ii) the operative fluency (low, normal, excellent), (iii) backaches (none, low, moderate, important), and (iv) headaches (range from 0 to 10). Age and sex were collected retrospectively. The procedures performed with 3D and BM were subsequently compared using univariate (χ2, Fisher, Wilcoxon) and multivariate analysis (generalized linear model), allowing us to identify parameters independently associated with PK surgery duration. Results: A total of 102 valid questionnaires, relative to 73 PK and 29 vitreoretinal procedures, respectively, were analysed. As regards PK (3D, n = 25 vs. BM, n = 48), the mean age, sex ratio, surgical risk, intraoperative complications (1/25 vs. 4/48), visual comfort, backaches, and headaches were similar between the two systems. The use of 3D allowed faster PK surgeries (16.44 ± 4.36 vs. 21.44 ± 7.50 min; p = 0.007) and slightly enhanced the operative fluency. In vitreoretinal surgeries (3D, n = 14 vs. BM, n = 15), no obvious differences between the two visualization systems were observed, although the use of the 3D system was found to slightly decrease the operative fluency. Parameters independently associated with PK surgery duration were 3D visualization (β = –4.4 ± 1.4; p = 0.002), high preoperative surgical risk (β = 6.2 ± 2.4; p = 0.012), intraoperative complications (β = 8.7 ± 2.6; p = 0.001), and surgeon status (β = –4.4 ± 1.3; p = 0.001) in univariate and multivariate analysis. Conclusions: 3D visualization can be safely used in routine practice. It slightly improves the operative fluency, allowing faster PK surgery.

Simple Summary Despite the impressive progress in the treatment of triple-negative breast cancer (TNBC), oncologists still face several provocative clinical scenarios in daily practice where clear evidence-based recommendations are lacking, and expert opinion is of utmost importance. In an attempt to seek guidance for these controversial topics in TNBC management, a consensus recommendations session for TNBC was held during the 12th round of the Breast-Gynaecological & Immuno-oncology International Cancer Conference (BGICC) Egypt, 2020. This special session convened a multidisciplinary committee of 35 panellists who specialize in breast cancer care from 13 countries. The consensus covered all the aspects of TNBC management starting from defining TNBC to the management of metastatic disease and highlighted the rapidly evolving landscape in this field. Consensus was reached in 70% of the statements (35/50). In addition, areas of warranted research were identified to guide future prospective clinical trials. Background: The management of patients with triple-negative breast cancer (TNBC) is challenging with several controversies and unmet needs. During the 12th Breast-Gynaecological & Immuno-oncology International Cancer Conference (BGICC) Egypt, 2020, a panel of 35 breast cancer experts from 13 countries voted on consensus guidelines for the clinical management of TNBC. The consensus was subsequently updated based on the most recent data evolved lately. Methods: A consensus conference approach adapted from the American Society of Clinical Oncology (ASCO) was utilized. The panellists voted anonymously on each question, and a consensus was achieved when >= 75% of voters selected an answer. The final consensus was later circulated to the panellists for critical revision of important intellectual content. Results and conclusion: These recommendations represent the available clinical evidence and expert opinion when evidence is scarce. The percentage of the consensus votes, levels of evidence and grades of recommendation are presented for each statement. The consensus covered all the aspects of TNBC management starting from defining TNBC to the management of metastatic disease and highlighted the rapidly evolving landscape in this field. Consensus was reached in 70% of the statements (35/50). In addition, areas of warranted research were identified to guide future prospective clinical trials.

Large brain arteriovenous malformations (AVMs) pose a management dilemma because of the limited success of any single treatment modality by itself. Surgery alone is associated with significant morbidity and mortality. Similarly, embolization alone has limited efficacy. Volume-staged Gamma Knife radiosurgery (VSGR) has been developed for the treatment of large AVMs to increase the efficacy and improve safety of treatment of these lesions. The aim of this study was to assess the efficacy and safety of VSGR technique for the treatment of large brain AVMs.The study included patients treated by VSGR between May 2009 and July 2015. All patients had large AVMs (10 mL). There were 29 patients.Twenty-four patients completed radiographic follow-up, with 15 obliteration cases (62.5%). A total of 56 sessions were performed. The mean AVM volume was 16 mL (range, 10.1-29.3 mL). The mean prescription dose was 18 Gy (range, 14-22 Gy). The mean follow-up duration was 43 months (range, 21-73 months). One patient died during follow-up of an unrelated cause. Two patients had hemorrhage during follow-up. Symptomatic edema developed in 5 patients (17%). The factors affecting obliteration were smaller total volume, higher dose/stage, nondeep location, compact AVM, AVM score3,18 Gy dose, and15 mL total volume. The factors affecting symptomatic edema were smaller total volume and shorter time between first and last sessions (P = 0.012). T2 image changes were affected by Spetzler-Martin grade ≥3 (P = 0.013) and AVM score ≥3 (P = 0.014).VSGR provides an effective and safe treatment option for large brain AVMs. Smaller AVM volume is associated with higher obliteration rate.

Background Atrial fibrillation represents a common complication after coronary artery bypass and valvular surgery, although it is a benign arrhythmia it may contribute to the morbidity, high cost and prolonged ICU stay. Objectives The purpose of this study is to investigate and analyze the incidence and risk factors associated with postoperative atrial fibrillation (POAF) and its impact on intensive care unit (ICU) and postoperative hospital stay in patients undergoing coronary artery bypass graft surgeries (CABG) at Ain Shams University hospitals using the medical records of patients who underwent(CABG) surgeries from July 2018 to July 2019. Patients and Methods Our study was conducted in Ain Shams University hospitals from July 2018 to July 2019. This study was a retrospective non randomized on total 660 patients who undergone isolated Coronary artery bypass graft surgeries (CABG) during this period, of them we targeted 100 cases who developed POAF after surgery. Results Our results show that age, history of hypertension,smoking,history of renal impairment and recent myocardial infarction were all predictors of atrial fibrillation after cardiac surgery. POAF developed more frequent in patients who had larger left atrium diameter and lower ejection fraction. Our present results indicate that there is significant association between longer bypass and cross clamping time and development of POAF. We also found that patients who had postoperative lower serum potassium experienced more frequent POAF than who had normal potassium levels. In our study, we found that use of preoperative beta blocking drugs reduces risk of developing POAF. Early electrocardiographic ischemic postop. changes was also associated with high risk to develop POAF. No significant relation between use of intra-aortic balloon pump and development of POAF. Also, no significant relation between POAF and development of stroke or thromboembolic manifestations as POAF is usually self limiting,transient and resolves spontaneously in most of cases. Conclusion The current study found that low ejection fraction, dilated left atrium, hypertension, smoking, old age, male gender, prolonged bypass time, prolonged cross clamping time, renal impairment, previous myocardial infarction, ungrafted dominant right coronary artery, low temperatures on bypass, early ischemic changes postoperative, hypokalemia, use of adrenaline and nor adrenaline, all of these factors were a significant predictors for development of atrial fibrillation after cardiac surgery.

To describe the clinical features, epidemiology, autoantibody status, HLA haplotypes and genetic mechanisms of type 1 diabetes mellitus (T1DM). Patients (0–18 years) with diabetes were recruited. Clinical data was collected, autoantibodies and c-peptide were measured. Whole Genome Sequencing was performed. Genomic data analysis was compared with the known genes linked with T1DM and HLA alleles were studied. 1096 patients had one or more antibody positivity. The incidence of T1DM in 2020 was 38.05 per 100,000 children and prevalence was 249.73. GADA was the most common autoantibody followed by IAA. Variants in GSTCD, SKAP2, SLC9B1, BANK1 were most prevalent. An association of HLA haplotypes DQA1*03:01:01G (OR = 2.46, p value = 0.011) and DQB1*03:02:01G (OR = 2.43, p value = 0.022) was identified. The incidence of T1DM in Qatar is the fourth highest in the world, IA2 autoantibody was the most specific with some patients only having ZnT8 or IA2 autoantibodies thus underlining the necessity of profiling all 4 autoantibodies. The genes associated with T1DM in the Arab population were different from those that are common in the Caucasian population. HLA-DQ was enriched in the Qatari patients suggesting that it can be considered a major risk factor at an early age.

Context Idiopathic type 1 diabetes is characterized by the absence of autoantibodies and the underlying mechanisms are not clear. Objective We aimed to study the epidemiology, describe the clinical characteristics, and report results of genetic studies in pediatric patients with idiopathic type 1 diabetes. Methods This was a prospective study of type 1 diabetes patients attending Sidra Medicine from 2018 to 2020. Autoantibodies (GAD65, IAA, IA-2A, and ZnT8) were measured and genetic testing was undertaken in patients negative for autoantibodies to rule out monogenic diabetes. Demographic and clinical data of patients with idiopathic type 1 diabetes were compared with patients with autoimmune type 1 diabetes. Results Of 1157 patients with type 1 diabetes, 63 were antibody-negative. Upon genome sequencing, 4 had maturity onset diabetes of the young (MODY), 2 had Wolfram syndrome, 1 had H syndrome, and 3 had variants of uncertain significance in MODY genes; 53 patients had idiopathic type 1 diabetes. The most common age of diagnosis was 10 to 14 years. C-peptide level was low but detectable in 30 patients (56.6%) and normal in 23 patients (43.4%) The average body mass index was in the normal range and 33% of the patients had a history of diabetic ketoacidosis (DKA). Conclusion Four percent of the children had idiopathic type 1 diabetes. There were statistically significant differences in the C-peptide level and insulin requirement between the 2 groups. DKA was less common in the idiopathic group. Mutations in MODY genes suggest the importance of autoantibody testing and genetic screening for known causes of monogenic diabetes in idiopathic type 1 diabetes. The mechanism of idiopathic type 1 diabetes is unknown but could be due to defects in antibody production or due to autoantibodies that are not yet detectable or discovered.

The current published literature regarding the role of hip arthroscopy in the diagnosis and management of post-traumatic hip pain is still limited. Therefore, we conducted the present prospective study to determine the value of hip arthroscopy in the diagnosis and management of various causes of hip pain after traumatic conditions. The present study included a prospective cohort of 17 patients with symptomatic post-traumatic hip pain. It was conducted between July 2013 and May 2018. The mean age was 22 (19–29) years and the mean follow-up was 24 (r: 7–36) months. Prior to surgery, every eligible patient underwent assessment of functional status using the Modified Harris Hip Score, Oxford hip score (OHS) and Western Ontario and McMaster Universities Arthritis Index (WOMAC) score. All patients underwent arthroscopic management for their diagnosed pathologies. The most commonly encountered diagnosis was labral tear (58.8%), followed by ligamentum teres tear (35.3%) and loose intra-articular fragments (29.4%). In addition, 52.9% of the patients had associated CAM lesion and 11.8% had associated Pincer lesion. The mHSS, OHS and WOMAC score showed significant improvement in the post-operative period (P

OBJECTIVERecurrent or residual adenomas are frequently treated with Gamma Knife radiosurgery (GKRS). The most common complication after GKRS for pituitary adenomas is hypopituitarism. In the current study, the authors detail the timing and types of hypopituitarism in a multicenter, international cohort of pituitary adenoma patients treated with GKRS.METHODSSeventeen institutions pooled clinical data obtained from pituitary adenoma patients who were treated with GKRS from 1988 to 2016. Patients who had undergone prior radiotherapy were excluded. A total of 1023 patients met the study inclusion criteria. The treated lesions included 410 nonfunctioning pituitary adenomas (NFPAs), 262 cases of Cushing’s disease (CD), and 251 cases of acromegaly. The median follow-up was 51 months (range 6–246 months). Statistical analysis was performed using a Cox proportional hazards model to evaluate factors associated with the development of new-onset hypopituitarism.RESULTSAt last follow-up, 248 patients had developed new pituitary hormone deficiency (86 with NFPA, 66 with CD, and 96 with acromegaly). Among these patients, 150 (60.5%) had single and 98 (39.5%) had multiple hormone deficiencies. New hormonal changes included 82 cortisol (21.6%), 135 thyrotropin (35.6%), 92 gonadotropin (24.3%), 59 growth hormone (15.6%), and 11 vasopressin (2.9%) deficiencies. The actuarial 1-year, 3-year, 5-year, 7-year, and 10-year rates of hypopituitarism were 7.8%, 16.2%, 22.4%, 27.5%, and 31.3%, respectively. The median time to hypopituitarism onset was 39 months.In univariate analyses, an increased rate of new-onset hypopituitarism was significantly associated with a lower isodose line (p = 0.006, HR = 8.695), whole sellar targeting (p = 0.033, HR = 1.452), and treatment of a functional pituitary adenoma as compared with an NFPA (p = 0.008, HR = 1.510). In multivariate analyses, only a lower isodose line was found to be an independent predictor of new-onset hypopituitarism (p = 0.001, HR = 1.38).CONCLUSIONSHypopituitarism remains the most common unintended effect of GKRS for a pituitary adenoma. Treating the target volume at an isodose line of 50% or greater and avoiding whole-sellar radiosurgery, unless necessary, will likely mitigate the risk of post-GKRS hypopituitarism. Follow-up of these patients is required to detect and treat latent endocrinopathies.

Background: With antiprogrammed death receptor-1 (anti-PD-L1) therapy, a recent meta-analysis reported higher incidence of cutaneous, endocrine and gastrointestinal complications especially with dual anti-PD-L1 immunotherapy (IMM). Methods: Our primary outcome was assessment of all cardiotoxicity grades in IMM compared with different treatments, thus a systemic review and a meta-analysis on randomized clinical trials (RCTs) were done. Results: We included 11 RCTs with 6574 patients (3234 patients in IMM arm vs 3340 patients in the other arm). Three non-small-cell lung cancer RCTs, seven melanoma RCTs and only one prostatic cancer RCT met the inclusion criteria. There were five RCTs that compared monoimmunotherapy to chemotherapy “(n = 2631 patients)”. No difference exists in all cardiotoxicity grades or high-grade cardiotoxicity (p > 0.05). Lung cancer exhibited a higher response rate and lower mortality in IMM. Conclusion: There was no reported statistically significant cardiotoxicity associated with anti-PD/PD-L1 use. Lung cancer subgroups showed better response and survival rates.

Objectives: Numerous studies addressed the effect of statin on cancer patients. The aim of this study is to define the effect of statin administration with chemotherapy on the patients’ outcomes. Methods: We retrospectively researched the database of the University of Cincinnati cancer to identify lung cancer patients who received statins (S+, n=41) during their treatment in our institute. We also, retrieved data for contemporaneously treated patients who did not receive statins (S-, n=159) as a control arm. Clinico-demographical data and overall survival (OS) were analyzed using Pearson’s Chi-square (χ2) test and Kaplan-Meier survival curves with Log-rank test. Adjustment using Cox proportional hazard ratios (HR) were done based on (age, gender, race and stage) to identify effect of statins on their outcomes. Results: The median age for S+ was 64y (IQR; 55-69) and 71.2% of the patients were white. Histopathology was 55.4% and 31.7% for adenocarcinoma and squamous cell carcinoma, respectively. Fifty-six percent were stage IV in each study arm and the median OS was14.9 m. Median OS was insignificantly lower in S–ve arm (13.7 vs 15.6 months; P=0.652, HR=0.91, 95%CI 0.52-1.57). Our results show that after different types of adjustments, S+ did not show survival advantage (P>0.05) compared to the control arm. Conclusion: While showing an increase in overall survival in patients with advanced lung cancer, the results of this study did not reach statistical significance. This could be due for the small sample size of this retrospective study.

OBJECTIVEThe objective of this study was to assess hearing function after Gamma Knife treatment of cerebellopontine angle (CPA) meningiomas and assess factors affecting hearing outcome. Additionally, the authors opted to compare these results with those after Gamma Knife treatment of vestibular schwannomas (VSs), because most of the information on hearing outcome after stereotactic radiosurgery (SRS) comes from reports on VS treatment. Hearing preservation, to the best of the authors’ knowledge, has never been separately addressed in studies involving Gamma Knife radiosurgery (GKRS) for CPA meningiomas.METHODSThis study included all patients who underwent a single session of GKRS between 2002 and 2014. The patients were divided into two groups. Group A included 66 patients with CPA meningiomas with serviceable hearing and tumor extension into the region centered on the internal auditory meatus. Group B included 144 patients with VSs with serviceable hearing. All patients had serviceable hearing before treatment (Gardner-Robertson [GR] Grades I and II). The median prescription dose was 12 Gy (range 10–12 Gy) in both groups. The median follow-up of groups A and B was 42 months (range 6–149 months) and 49 months (range 6–149 months), respectively.RESULTSAt the last follow-up, the tumor control rate was 97% and 94% in groups A and B, respectively. Hearing preservation was defined as maintained serviceable hearing according to GR hearing score. The hearing preservation rate was 98% and 66% and the 7-year actuarial serviceable hearing preservation rate was 75% and 56%, respectively, between both groups. In group A, the median maximum cochlear dose in the patients with stable and worsened hearing grade was 6.3 Gy and 5.5 Gy, respectively. In group B, factors affecting hearing preservation were cochlear dose ≤ 7 Gy, follow-up duration, and tumor control. The only determinant of hearing preservation between both groups was tumor type.CONCLUSIONSGKRS for CPA meningiomas provides excellent hearing preservation in addition to high tumor control rate. Hearing outcome is better with CPA meningiomas than with VSs. Further long-term prospective studies on determinants of hearing outcome after GKRS for CPA meningiomas should be conducted.

Aim: To determine the prevalence and describe the antimicrobial resistance patterns of circulating methicillin-resistant staphylococci (MRS) isolated from clinical specimens during a 3-year period in Yaoundé, Cameroon. Materials & methods: From January 2017 to December 2019, 1683 clinical samples were plated onto Mannitol salt agar. Bacterial identification was performed followed by antibiotic susceptibility testing. Data were analyzed using R program. Results: Staphylococci were identified in 90 (5.35%) of the 1683 clinical samples. Among these, 83.33% were MRS with 78.67% being methicillin-resistant Staphylococcus aureus (MRSA). The prevalence of MRS infection increased significantly with age. Conclusion: The study offers a good baseline for surveillance intervention to contain antimicrobial resistance and highlights the need to strengthen antimicrobial stewardship and infection, prevention and control programs in the country., Lay abstract Antimicrobial resistance is an increasing concern worldwide with several health, societal and economic consequences. Methicillin-resistant staphylococci (MRS) is among the leading cause of difficult-to-treat infections. There is a lack of data regarding the burden of MRS in the private healthcare sector in Cameroon. Hence, the current study was performed to fill the observed gaps. We found that MRS is highly prevalent (80%) in the country and increased significantly with age. Our study provides evidence for reinforcing surveillance and prevention measures to contain MRS and by extension antimicrobial resistance in Cameroon., Graphical abstract

BACKGROUND Glomus Jugulare tumors are benign but locally aggressive ones that represent a therapeutic challenge. Previous studies about the use of Gamma Knife Radiosurgery (GRS) in those tumors have documented good results that needed larger number of patients and longer follow up periods to be confirmed. MATERIAL AND METHODS Between August 2001 and December 2017, 70 patients with glomus jugulare tumors were treated at the Gamma Knife Center, Cairo. They were 46 females and 24 males. The mean age was 48 years (16–71 years). Nineteen of these patients were previously operated, 5 were partially embolized, 3 underwent embolization and subsequent surgery and 43 had gamma knife as their primary treatment. Volume-staged gamma knife radiosurgery was used in 10 patients and single-session in 60 patients, with a total of 86 sessions. The mean target volume was 12.7 cm3 (range 0.2 to 34.5 cm3). The mean tumor volume was 15.5 cm3 (range 0.2 to 105 cm3). The mean prescription dose was 14.5 Gy (range 12 to 18 Gy). RESULTS The mean follow up period was 60 months (range 18 to 206 months), and by the time of the data analysis, two of the patients were dead (66 and 24 months after GK treatment). The tumor control was 98.6% (69/70). Thirty-two tumors became smaller and 37 were unchanged. The symptoms improved in 36 patients, were stable in 32 patients, and worsened in 2 patients who developed a transient facial palsy and worsened hearing. Symptomatic improvement began before any reduction in tumor volume could be detected, where the mean time to clinical improvement was 7 months whereas the mean time to tumor shrinkage was 18 months. CONCLUSION This study about the long term follow up of the GKR for the intracranial glomus jugulare tumors confirmed that this is a highly effective and safe treatment. This data shows that the clinical improvement is not correlated with the radiological volume reduction.

In most individuals, there is a significant difference in hand dominance and this suggests that sensorimotor tasks, such as reaction time, would demonstrate a difference in performance tasks conducted with dominant versus non-dominant hand. In this study, comparisons were made between the reaction time of the dominant to the nondominant hand, the reaction time of the male participants to that of the female participants, the reaction time variability of the dominant hand of the male participants to that of the dominant hand of female participants, and finally the reaction time variability of the nondominant hand of the male participants to that of the female participants. The study was conducted virtually with participants performing a set of instructions emailed to them. The results demonstrated that the reaction time of the dominant hand was faster than that of the nondominant hand in all participants, the reaction time of the male participants was faster than that of the female participants, the reaction time variability of the dominant hand was higher in male than in female participants, and lastly, the reaction time variability of the nondominant hand was lower for the male than in the female participants.

Digital, Non-alcoholic fatty liver disease (NAFLD) is a potentially serious liver disease that affects approximately one-quarter of the global adult population, causing a substantial burden of ill health with wide-ranging social and economic implications. It is a multisystem disease and is considered the hepatic component of metabolic syndrome. Unlike other highly prevalent conditions, NAFLD has received little attention from the global public health community. Health system and public health responses to NAFLD have been weak and fragmented, and, despite its pervasiveness, NAFLD is largely unknown outside hepatology and gastroenterology. There is only a nascent global public health movement addressing NAFLD, and the disease is absent from nearly all national and international strategies and policies for non-communicable diseases, including obesity. In this global Delphi study, a multidisciplinary group of experts developed consensus statements and recommendations, which a larger group of collaborators reviewed over three rounds until consensus was achieved. The resulting consensus statements and recommendations address a broad range of topics — from epidemiology, awareness, care and treatment to public health policies and leadership — that have general relevance for policy-makers, health-care practitioners, civil society groups, research institutions and affected populations. These recommendations should provide a strong foundation for a comprehensive public health response to NAFLD., Ciencias Médicas y de la Salud

Background The use of stereotactic radiosurgery for the treatment of intracranial meningiomas has been established as an effective and safe treatment modality. Larger meningiomas typically are managed by surgery followed by radiosurgery. Treatment of large meningiomas (usually defined as >10 cc) by stereotactic radiosurgery has been investigated in some recent reports, either by single-session, volume-staged, or the hypofractionation technique. We sought to assess the long-term efficacy and safety of single-session stereotactic radiosurgery for large (10 cc or more) intracranial benign meningiomas. Patients and Methods In this retrospective study, we included 273 patients with large benign meningiomas (≥10 cc) who were treated by single-session SRS and followed up for more than 2 years. Tumors were in a basal location in 228 patients (84%). There were 161 tumors (59%) in the perioptic location. The median tumor volume was 15.5 (10–57.3 cc [interquartile range {IQR} 12.3 cc]). The median prescription dose was 12 Gy (9–15 Gy [IQR 1 Gy]). Results The median follow-up period was 6.1 years (2–18 years [IQR 5.5 years]). The tumor control rate was 90%. The progression-free survival at 5 and 10 years was 96% and 81%, respectively, for the whole cohort. Among 161 patients with perioptic meningiomas, favorable (better/stable) visual outcome was reported in 155 patients (96%) and unfavorable (worse) outcome in 6 patients (4%). Temporary adverse radiation effects were observed in 41 patients (15%) but only 16 (6%) were symptomatic. Conclusions Stereotactic radiosurgery provides an effective and safe treatment option for large meningiomas.

Background Osteoporosis is a common complication of ankylosing spondylitis (AS) even in the early stages of disease; however, previously published studies have demonstrated large discrepancies in the reported incidence of osteoporosis, based on measurement of bone mineral density (BMD). The aim of the present study was to compare bone quality using trabecular bone score (TBS) between AS patients and healthy controls and to evaluate factors associated with TBS in patients with AS. Results Ankylosing spondylitis patients had significantly lower BMD and T score at the neck of femur and lower total hip BMD than controls (BMD p = 0.010 and 0.032 respectively), (T score p = 0.006 and p = 0.025 respectively). The mean TBS was significantly lower in AS patients than in controls (p < 0.001). Lumbar spine TBS was directly correlated with BMI (p = 0.029) and BMD at the neck of femur (p = 0.016) and BMD of total hip (p = 0.007) while inversely correlated with the Bath AS Metrology Index (BASMI) (p = 0.026), the modified Stoke AS Spinal Score (mSASS) (p = 0.029), ESR (p = 0.031), and CRP (p = 0.033). Conclusion TBS evaluation detected lower bone quality in the lumbar spine in patients with AS when compared with matched controls, while lumbar BMD failed to identify it. These findings encourage the use of TBS as a beneficial tool to recognize the risk of axial osteoporosis as early as possible in AS patients. Also, we recommend its use for regular follow up of drug treatment for those patients.

Child abuse leads to substantial health problems and is extremely worrisome to the pediatric medical community. The child presented in our case was a victim of severe physical abuse leading to rhabdomyolysis, AKI, subsequently requiring renal replacement therapy. The objective of this case is to raise awareness and advise checking renal function, CK and myoglobin in bruised children subjugated to physical abuse. Child abuse leading to severe decline in renal function is rare and needs to be recognized in a timely manner and adequately treated.

The proximal femur is a common area for primary and also metastatic bone tumors. The objective of this study was to assess the long-term functional and oncological outcomes of patients with malignant primary or secondary tumors of the proximal femur, who underwent proximal femoral resection then reconstruction using bipolar modular tumor prosthesis. Sixty patients with proximal femoral malignant tumors underwent resection and bipolar modular prosthesis between 2000 and 2016, were retrospectively reviewed. Based on diagnosis and presence or absence of pathological fracture, patients were divided into groups. The functional outcome of the patients was evaluated using the Musculoskeletal Tumor Society (MSTS) functional scoring system for the lower extremities. The mean age was 38 (9–80) years at the time of primary surgery. Pathological fracture was the presentation in 28 patients. The study included 44 patients with primary bone tumor and 16 patients with a secondary bone tumor. The mean MSTS functional score of the patients was 24.3 (range, 18–30) points with no significant difference in patients with primary or secondary tumors. The rate of complications in the present series was 45%. The most frequent complication was an infection in 10 patients (16.7%), followed by aseptic loosening in 7 patients (11.7%). Local recurrence of primary bone tumors occurred in three out of 44 patients (6.8%). Modular bipolar tumor prosthesis has a good long-term functional result in both primary and secondary tumors of the proximal femur, with no significant effect of age, presence or absence of pathological fracture or femoral resection length on the functional outcome. It was found that the only statistically significant variable regarding the risk of infection is previous surgeries. Level IV, retrospective case series.

Background: Diabetic Retinopathy (DR) is one of the long-term complications of Diabetes Mellitus (DM) and constitutes the leading cause of blindness in working-age individuals. Prolactin (PRL) is a peptide hormone that is linked with lactation but many studies have demonstrated that PRL could have protective value against DR. Aim: To evaluate the role of prolactin in pathophysiology of DR. Methods: This study is designed to find an association between PRL level and DR. In this case-control study, a total of 300 subjects were recruited to participate in the study, 150 subjects apparently healthy as control group and other 150 patients were diagnosed with type 2 DM who were classified into diabetic patients with DR (75) and diabetic patients without DR (75). Serum PRL was measured by autoanalyzer (TOSOH AIA system), HbA1c was measured by another automated chemical analyzer (Cobas c system). Statistical analysis was performed using SPSS version 21 using an independent samples T-test and Pearson's correlation. Results: Independent samples of T-test analysis show a significant decrease in PRL level in the diabetic patients with DR in comparison to the diabetic patients without DR (p˂0.05). Person's correlation revealed that there was an insignificant correlation between PRL level with duration of DM and patients age. Conclusion: These findings suggest that low PRL level might be associated with DR.

Background: traditional methods for evaluation of women with urinary incontinence include urodynamic studies with measuring the pressure in the abdomen, the bladder, and the urethra and urine flow analysis. In addition, cysto-urethroscopy, cysto-urethrography are used for visualization of the bladder and the urethra. Aim of the Study:urinary continence depends on a closed and empty urethra with high urethral pressure. High urethral pressure (Pura) depends on two factors; one is structural which is defined as damage and lacerations in the collagen chassis of the internal urethral sphincter (IUS), the second factor is acquired functional factor is having and maintaining high sympathetic tone at the IUS from toilet training. Patients and Methods: 40 women who from SUI are examined clinically and investigated with sonar scanning 3DUS. 20 cases control by 3DUS. Patients with primary infertility those who had no vaginal deliveries, did not suffer cognitive behavioral therapy. This study is done at Bab El-Sharia Maternity University Hospital during the period from January 2017 to June 2018. Result:the IUS, as it is a cylinder, the level and extent of the rupture along the cylinder will determine the type and the degree of urinary incontinence as well as the configurational shape seen on imaging (case with primary infertility two years ago). Conclusion: we conclude that damage of the IUS leads low pura and stress urinary incontinence (SUI). Childbirth trauma causes damage to the collagen layer (the frame) of the vagina that leads to redundancy of the vagina and vaginal prolapse.

Background: pregnancy represents an important challenge in the female's life that she needs close observation during it and also needs counseling by her physician about the changes that are going through her body in this stressful period. Aim of the Work: the purpose of our study was to detect the changes that occur in the women's eyes during pregnancy and postpartum period regarding intraocular pressure and refraction. Patients and Methods: we studied 40 pregnant healthy women whose ages ranged from 18 to 35 years and we exclude any ocular diseases such as keratoconus, amblyopia or diabetic retinopathy. We measured the intraocular pressure using a Goldmann applanation tonometer, best corrected visual acuity using the Snellen's chart and k reading using autorefractor-keratometer. Results: we found that the IOP decreases only in the 3rd trimester with more decrease in women with multiple fetuses and multiple pregnancies. We found that the BCVA decreases only in the 2nd and 3rd trimesters. We also found that the K reading increases only in the 2nd and 3rd trimesters. Intraocular pressure, best corrected visual acuity and k reading returned to the normal values after delivery. Conclusion: the physiologic changes that occur in the women's eyes during pregnancy and postpartum period are usually marked in second and third trimester; this is because at this period, hormonal activity is at its peak, and however these changes are transient because several weeks postpartum, all hormonal activities return to their prenatal levels.

Background Stereotactic radiosurgery (SRS) is a highly effective management approach for patients with vestibular schwannomas (VS), with 10-yr control rates up 98%. When it fails, however, few data are available to guide management. Objective To perform a retrospective analysis of patients who underwent 2 SRS procedures on the same VS to assess the safety and efficacy of this practice. Methods This study was opened to centers of the International Gamma Knife Research Foundation (IGKRF). Data collected included patient characteristics, clinical symptoms at the time of SRS, radiosurgery dosimetric data, imaging response, clinical evolution, and survival. Actuarial analyses of tumor responses were performed. Results Seventy-six patients from 8 IGKRF centers were identified. Median follow-up from the second SRS was 51.7 mo. Progression after the first SRS occurred at a median of 43 mo. Repeat SRS was performed using a median dose of 12 Gy. Actuarial tumor control rates at 2, 5, and 10 yr following the second SRS were 98.6%, 92.2%, and 92.2%, respectively. Useful hearing was present in 30%, 8%, and 5% of patients at first SRS, second SRS, and last follow-up, respectively. Seventy-five percent of patients reported stable or improved symptoms following the second SRS. Worsening of facial nerve function attributable to SRS occurred in 7% of cases. There were no reports of radionecrosis, radiation-associated edema requiring corticosteroids, radiation-related neoplasia, or death attributable to the repeat SRS procedure. Conclusion Patients with progressing VS after radiosurgery can be safely and effectively managed using a second SRS procedure.

Objectives To evaluate and categorize the survival benefit of tricyclic antidepressants (TCAs) in lung cancer patients based on systematic computational drug repositioning data. Methods Data were retrospectively extracted from the medical records of non-small cell lung cancer (NSCLC) patients from the University of Cincinnati Cancer Medical Center database. Patients receiving antidepressants during their course of anti-cancer treatment were compared with those without antidepressants. Data were analyzed using Kaplan–Meier survival curves with the log-rank test, and overall survival (OS) was calculated from the date of diagnosis until last follow-up or death. Results The median OS at 2 and 5 years for patients on antidepressants was 20.3 months (54.7% and 42%) vs 44.3 months (47.6% and 43.2%), which was not significant. The median OS for patients receiving TCAs, selective serotonin reuptake inhibitors, and other antidepressants was 3.17 months, 31.33 months, and 18.50 months, respectively. Conclusion We found no significant survival benefit for TCA use in combination with anti-cancer agents in NSCLC patients.

Background Different treatment options were used to treat upper ureteral calculi. The aim of our study is to compare the stone-free rate and postoperative outcomes between semirigid ureteroscope with holmium laser lithotripsy and laparoscopic ureterolithotomy for the management of large solitary upper ureteral stones. Sixty-seven patients with a solitary upper ureteral stone who had LU or semirigid ureteroscopy in the period between January 2014 and March 2017 were included in our study. Out of the sixty-seven patients, 37 patients had semirigid ureteroscopy and holmium laser lithotripsy (Group A) and 30 patients had laparoscopic ureterolithotomy (Group B). Both groups were compared regarding operative time, intraoperative complications, need for auxiliary procedures, hospital stays, postoperative complications and stone-free rate. Results The mean stone size was 1.84 ± 0.12 cm in Group A and 1.79 ± 0.17 cm in Group B, P value = 0.2. The mean operative time was 61.5 ± 3.5 min in Group A and 63 ± 4.2 min in Group B, P value = 0.13. Stone migration was recorded in five cases (14%) in Group A while no cases in Group B had stone migration. Flexible ureteroscope was used as an auxiliary measure in five patients (14%) in Group A at the same session. No auxiliary measures were used in the LU group. Conclusion The stone-free rates after semirigid URS and laser lithotripsy are comparable to those following LU, especially when flexible URS is used to manage migrating stone fragments at the same session.

INTRODUCTION Stenting has advanced the treatment of coronary artery disease, with angiography being historically the gold standard to assure adequate stent deployment. However, intravascular imaging modalities including intravascular ultrasound and optical coherence tomography have shown high rates of inadequate stent deployment in angiographically optimized stents. The association of malapposition with adverse clinical outcomes remains controversial. Areas covered: The definition, types, and risk factors for metallic stent malapposition, the natural history, and significance of stent strut malapposition and its correlation with short- and long-term outcomes were reviewed. Expert commentary: Using intravascular imaging, acute stent strut malapposition is very common, occurring in >75% in some studies. Malapposition may be a result of inadequate stent deployment technique or the atherosclerotic process itself. The preponderance of available data suggests that acute malapposition is not associated with worsened outcomes. Late acquired malapposition may be associated with a relatively increased event rate for stent thrombosis and myocardial infarction but the increased risk is quite small (

Skin grafting is integral to burn wound management andis the only way of providing permanent wound closure of fullthickness burn and deep partial thickness burn that fails toheal within 3 weeks. Successful auto-grafting is the key topatient survival. With periodic change in the team of surgicaltrainees working in the burn unit, it was considered necessaryto develop a protocol for the skin grafting procedure. Implementationof this protocol was expected to yield uniformoutcome despite change in the operating team.Validation of this protocol was considered necessary toevaluate its efficacy. This study was carried out over a periodof 12 months from 2014 to 2015.

Background: Glioblastoma multiforme (GBM) is the most common and most malignant of the glial tumors. Optimum management consists of maximal safe surgical resection, followed by concurrent chemo-radiotherapy treatment then adjuvant chemotherapy with temozolomide. A considerable part from the care of patients with GBM involves general medical management, containing corticosteroids. Despite steroids common use, there is experimental and clinical evidence that corticosteroids have direct effects on tumor cell proliferation and apoptosis. Aim of the Work: was to discuss the clinical relation between corticosteroids usage in Glioblastoma Multiforme (GBM) patients and quality of life as well as the disease progression free survival according to the recorded data from the joined hospitals. Patients and Methods: Retrospective analysis of 66 adult patients diagnosed with GBM by surgery or imaging criteria. In order to assess the relation between corticosteroid dependence and the survival, patients were recruited into two groups (arms) according to dependency. Arm (A) was steroid dependent (34 patients) and arm (B) was steroid non-dependent (32 patients). Results: Corticosteroids dependency was statistically significant correlated to both Overall Survival (OS)(median 2.5 in arm (A) vs. 13.1 months in the arm (B), p < 0.001), and Progression-free survival ratio (PFS)(median 2.3 in arm (A) vs. 9.4 months in arm (B), p = 0.035). Also, steroid dependency was independent prognostic factor by doing the COX regression analysis. Conclusion: Dependence on corticosteroids during course of treatment is identified as a poor prognostic factor.

Aim of the Study: Description of the results of using the stapler based ileal neobladders for reconstruction after radical cystectomy in a subset of patients in the National Cancer Institute of Cairo University in Egypt in terms of functional outcome and patient satisfaction.Patients and Methods: In 2014, A prospective interven-tional study was carried out in the National Cancer Institute involving 29 patients with bladder cancer who met the criteria for neobladder reconstruction after radical cystectomy for whom a modified Y shaped ileal neobladder was created after tumor exanteration aiming at exploring functional outcomes and patient satisfaction rates for a period of one year in such a group of patients compared to other published reconstructive options.Results: The mean value of maximum neobladder capacity was 445ml, the mean pressure at maximum neobladder capacity was 22cm H2O and the mean post-voiding urine residual was about 20ml. By 6 months' post operatively, about 85% of the cases expressed having a good quality of life evidenced by satisfaction about their body image, daily maintenance and general satisfaction.Conclusion: Orthotopic neobladder reconstruction using the Y (Fontana) ileal neobladder can be considered as a simple and practical solution for neobladder reconstruction after radical cystectomy in Egyptian bladder cancer patients.

Three cases from 2 institutions are presented in which patients developed asystole and/or severe bradycardia following the use of regadenoson for myocardial perfusion imaging (MPI), potential causes are posited, and directed therapy is suggested. The first case is that of an 81-year-old man with

Results: There was no significant difference in survival of patients treated with chemotherapy alone (median, 256 days) compared to patients not undergoing treatment (median, 205.5 days). Patients who underwent surgery and adjuvant chemotherapy showed a trend in improvement of survival (median, 457.6 days). Patients requiring only surgery had the longest OS of 713.5 days. Conclusions: Systemic chemotherapy alone did not improve survival in patients with PSC. Surgery provides the greatest overall survival benefit and adjuvant chemotherapy may also improve survival. Methods: From 2000 to 2014, twenty-five patients with pathologically confirmed PSC were treated at UCMC. The outcomes were retrospectively analyzed by treatment with overall survival (OS) as the endpoint.

A 65-year-old with non-small cell lung cancer developed autoimmune haemolytic anaemia while receiving pembrolizumab containing chemoimmunotherapy. Initially thought to be due to pembrolizumab induced haemolysis, he was treated with steroids, and pembrolizumab was held. Haemolysis was refractory to steroids and blood was observed to agglutinate in cold room temperatures. Cold agglutinins in high titre and monoclonal serum IgM kappa protein were detected. Bone marrow biopsy showed marginal zone lymphoma confirming low grade B-cell lymphoma causing cold agglutinin disease. B-cell depletion by rituximab stopped haemolysis, and pembrolizumab was safely continued for lung cancer.

Introduction Quadrilateral plate fractures constitute one of the most challenging components of acetabular fractures. The objective of this study is to describe and evaluate the novel technique of buttress screw fixation of the quadrilateral plate component of the acetabular fractures. Patients & methods Forty cases of acetabular fracture with associated quadrilateral plate component were included in the study. Mean age was 35 years (range, 16 − 68 years), with a mean follow-up 16.4 months (range, 9 − 36 months). Fixation of the quadrilateral plate was achieved by one or more buttress screws. The screws were inserted through the reconstruction plate, and placed close to the edge of the pelvic brim. To effectively achieve the 3-point fixation principle, the screw was inserted through the plate hole then outside the bone rubbing on the pelvic surface of the quadrilateral plate. Results Anatomical reduction of the quadrilateral plate component of the fractures was achieved in all but one patient. The modified Merle D’Aubigne and Postel score was excellent in 13 cases, good in 23 cases, fair in three cases, and poor in one case. No screw displacement or failures were observed during follow-up evaluation. No major complications related to this technique were observed in this series. Conclusion Buttress screw fixation of the quadrilateral plate fracture component in associated acetabular fractures is a safe and effective technique for reduction and fixation of these challenging fractures with no major complications related to this novel technique.

Uterine perforation is a serious complication after insertion of an intrauterine device (IUD). We report the case of a 34-year-old woman receiving in consultation for abdominal pain. In the interrogation there was a notion of IUD insertion for about a week. The gynecological examination did not find the thread of IUD and the ultrasound performed did not visualize an IUD. Radiography of the abdomen without preparation highlighted a compatible intrapelvic foreign thing like an IUD. The diagnosis of pelvic inflammatory disease by uterine perforation by an IUD was thus retained. We suggest in case of suspicion of uterine radio paque IUD perforation achieving radiography when the abdominal pelvic ultrasound is normal.
