Published: September 2019

ObjectivesGlaucoma filtering schemes such as the Manchester Glaucoma Enhanced Referral Scheme (GERS) aim to reduce the number of false positive cases referred to Hospital Eye Services. Such schemes can also have wider system benefits, as they may reduce waiting times for other patients. However, previous studies of the cost consequences and wider system benefits of glaucoma filtering schemes are inconclusive. We investigate the cost consequences of the Manchester GERS.DesignObservational study.MethodsA cost analysis from the perspective of the National Health Service (NHS) was conducted using audit data from the Manchester GERS.Results2405 patients passed through the Manchester GERS from April 2013 to November 2016. 53.3% were not referred on to Manchester Royal Eye Hospital (MREH). Assuming an average of 2.3 outpatient visits to MREH were avoided for each filtered patient, the scheme saved the NHS approximately £2.76 per patient passing through the scheme.ConclusionOur results indicate that glaucoma filtering schemes have the potential to reduce false positive referrals and costs to the NHS.

BackgroundPaediatric complex chronic conditions (CCCs) are life-limiting conditions requiring paediatric palliative care, which, in Belgium, is provided through paediatric liaison teams (PLTs). Like the number of children and adolescents with these conditions in Belgium, their referral to PLTs is unknown.ObjectivesThe aim of the study was to identify, over a 5-year period (2010–2014), the number of children and adolescents (0–19 years) living with a CCC, and also their referral to PLTs.MethodsInternational Classification of Disease codes (ICD-9) corresponding to a CCC, as described by Feudtneret al, and national registration numbers were extracted from the databases of all hospitals (n=8) and PLTs (n=2) based in the Brussels region. Aggregated data and pseudonymised national registration number were transmitted to the research team by a Trusted Third Party (eHealth). Ages and diagnostic categories were calculated using descriptive statistics.ResultsOver 5 years (2010–2014) in the Brussels region, a total of 22 721 children/adolescents aged 0–19 years were diagnosed with a CCC. Of this number, 22 533 were identified through hospital registries and 572 through PLT registries. By comparing the registries, we found that of the 22 533 children/adolescents admitted to hospital, only 384 (1.7%) were also referred to a PLT.ConclusionIn Belgium, there may be too few referrals of children and adolescents with CCC to PLTs that ensure continuity of care.
Endoscopic Mucosal Resection of a Proximal Esophageal Pyogenic Granuloma
Authors: Estifan Elias , Patel Varun , Grossman Matthew 
Published: September 2019

Pyogenic Granuloma (PG), also known as lobular capillary hemangioma, is usually seen as a polypoid red lesion found on the skin or the mucosal surface of the oral cavity. PG of the gastrointestinal tract is rare, in particular involving the esophagus, only 14 cases have been reported in the English literature. We present an 80-year-old male who underwent endoscopy for evaluation of dysphagia and was found to have a single, red, bilobed 10 mm polyp with adherent white exudate approximately 19 cm from the incisors. Endoscopic ultrasound was performed with a 20 mHz miniprobe which showed the lesion contained to the mucosal layer with no muscularis propria invasion. A decision was made to perform endoscopic mucosal resection (EMR). A mixture of saline and methylene blue was injected into the submucosal plane to raise the lesion with subsequent successful mucosal hot snare resection. The resection defect was then approximated and closed with a hemostatic clip to prevent bleeding. Pathology of the specimen revealed small capillary vessels growing in a lobular architecture with an edematous stroma and a florid inflammatory infiltrate representing a pyogenic granuloma. EMR allows for an en bloc resection of mucosal lesions with tumor-free margins, thereby providing both diagnostic and prognostic information. Comparing EMR with the novel technique of endoscopic submucosal dissection (ESD), the incidence of bleeding and perforation is much lower; making EMR the best and safest resection option for this rare hemangioma. In this case, we demonstrate that EMR is a safe technique in removing a pyogenic granuloma in the esophagus.

Abstract

Purpose:
Selective progesterone receptor modulators (SPRMs) show preclinical activity against hormone-sensitive breast cancer, but have not been tested in patients with early, treatment-naïve tumors.

Patients and Methods:
In a double-blind presurgical window trial of oral telapristone acetate (TPA) 12 mg daily versus placebo, 70 patients with early-stage breast cancer were randomized 1:1 (stratified by menopause) and treated for 2 to 10 weeks. The primary endpoint was change in Ki67 between diagnostic biopsy and surgical specimens. Gene expression pre- and posttherapy was assessed using RNA-sequencing and gene set enrichment analysis was performed to determine pathways enriched in response to TPA and placebo treatments.

Results:
Among 61 evaluable women (29 placebo and 32 telapristone acetate), 91% of tumors were ER/PR positive. The mean Ki67 declined by 5.5% in all women treated with telapristone acetate (P = 0.003), and by 4.2% in all women treated with placebo (P = 0.04). After menopausal stratification, the Ki67 decline remained significant in 22 telapristone acetate–treated premenopausal women (P = 0.03). Differential gene expression analysis showed no significant modulation overall. However, in a subset of tumors that demonstrated ≥30% relative reduction in Ki67 in the telapristone acetate group, genes related to cell-cycle progression, and those in the HER2 amplicon were significantly downregulated. In contrast, no significantly enriched pathways were identified in the placebo group.

Conclusions:
Patients treated with telapristone acetate whose Ki67 decreased by ≥30% demonstrated a selective antiproliferative signal, with a potentially important effect on HER2 amplicon genes. Evaluation of SPRMs in a neoadjuvant trial is merited, with attention to predictors of response to SPRM therapy, and inclusion of pre- and postmenopausal women.

Abstract

Angiosarcoma is a highly aggressive cancer of blood vessel–forming cells with few effective treatment options and high patient mortality. It is both rare and heterogenous, making large, well-powered genomic studies nearly impossible. Dogs commonly suffer from a similar cancer, called hemangiosarcoma, with breeds like the golden retriever carrying heritable genetic factors that put them at high risk. If the clinical similarity of canine hemangiosarcoma and human angiosarcoma reflects shared genomic etiology, dogs could be a critically needed model for advancing angiosarcoma research. We assessed the genomic landscape of canine hemangiosarcoma via whole-exome sequencing (47 golden retriever hemangiosarcomas) and RNA sequencing (74 hemangiosarcomas from multiple breeds). Somatic coding mutations occurred most frequently in the tumor suppressor TP53 (59.6% of cases) as well as two genes in the PI3K pathway: the oncogene PIK3CA (29.8%) and its regulatory subunit PIK3R1 (8.5%). The predominant mutational signature was the age-associated deamination of cytosine to thymine. As reported in human angiosarcoma, CDKN2A/B was recurrently deleted and VEGFA, KDR, and KIT recurrently gained. We compared the canine data to human data recently released by The Angiosarcoma Project, and found many of the same genes and pathways significantly enriched for somatic mutations, particularly in breast and visceral angiosarcomas. Canine hemangiosarcoma closely models the genomic landscape of human angiosarcoma of the breast and viscera, and is a powerful tool for investigating the pathogenesis of this devastating disease.

Implications:
We characterize the genomic landscape of canine hemangiosarcoma and demonstrate its similarity to human angiosarcoma.

Background: Endoscopic submucosal dissection (ESD) is a standard treatment for tumors of the gastrointestinal tract. We developed a self-completion method of ESD using Endosaber to eliminate the need for an additional device or human assistance during the procedure. The aim of this study was to evaluate the technical feasibility and outcomes of this method in an ex vivo porcine training model. Methods: This was a pilot study, and the procedures were performed by 4 experts. Mock lesions measuring 15 mm in diameter were prepared at the posterior wall in the middle or lower esophagus obtained from domestic pigs. Each operator performed ESD on the mock lesions in 3 models. The primary outcome was ESD completion rate using the self-completion method. The secondary outcomes were procedure time, en bloc resection rate, perforation rate, and number of injections during the procedure. Results: All 12 ESDs were completed using the self-completion method. The median procedure time (interquartile range) was 483.5 (399–619.3) s (median incision time: 240.4 [168.3–332.5] s; median dissection time: 222 [182.8–257] s). En bloc resection rate was 100%. No perforation was noted during any of the procedures. The median number of injections was 10.5 (9–14.3). The procedure time decreased significantly with increase in experience (p = 0.020). Conclusions: The self-completion ESD method using one Endosaber without any assistance achieved a 100% en bloc resection rate without any perforation. The need for an additional device or assistance was successfully eliminated. This method may prove to be a simple and cost-effective ESD procedure for lesions in humans.
Is Nasal Skin Thickness a Prognostic Indicator to Postoperative Edema and Ecchymosis?
Authors: Aldosari Badi 
Published: September 2019

Background: The size, shape, and symmetry of the nose contribute significantly to the facial aesthetic, so it is understandable why rhinoplasty is one of the most popular cosmetic procedures undertaken nowadays. Several factors are associated with the rates of both success and postoperative complications of rhinoplasty. Aim: To determine the relationship between nasal skin thickness and postoperative periorbital ecchymosis and edema among patients who underwent rhinoplasty at King Abdulaziz University Hospital. Methodology: A prospective study was conducted among all patients operated on for rhinoplasty at King Abdulaziz University Hospital in the Department of Otolaryngology, Riyadh, Saudi Arabia, between May and December 2018. To determine the relationship between nasal skin thickness and postoperative periorbital edema and ecchymosis, demographic data (gender, age), mean nasal skin thickness, surgical factors (time of surgery, extent of intraoperative bleeding), and scoring for periorbital ecchymosis and edema were obtained. The statistical analysis was done by comparing means and frequency using analysis of variance. Results: A total of 54 patients participated in this study with ages ranging from 19 to 33 years and a mean age of 24.43. According to this study, postoperative edema presentation on the first, third, and seventh days upon examination was higher among patients with thicker nasal skin (6 mm), and results are statistically significant ( P = .001). Ecchymosis was also higher among patients with thicker nasal skin (6 mm) on day 1 examinations, but there was no correlation with nasal thickness during the other examinations. Therefore, there is some degree of correlation between ecchymosis and nasal skin thickness overall, but the results are not significant ( P = .26). Conclusion: This study concludes that the severity of edema and ecchymosis correlates with nasal skin thickness. The degree of edema and ecchymosis was higher during the initial postoperative examinations, but following that, it was reduced and completely diminished by the 21st day post-surgery.
Evaluating the Clinical Outcomes of Parotid Hemangiomas in the Pediatric Patient Population
Authors: Harris Jacqueline , Phillips James D. 
Published: September 2019

Introduction: Infantile hemangiomas (IHs) are the most common tumor of the parotid gland in children; however, there is no standard protocol for the treatment of IH. The generally accepted practice is to begin the patient on β-blocker therapy if there are no contraindications. Objective: The purpose of this study is to better understand the challenges and successes of management of pediatric patients with parotid IH. Methods: This retrospective study analyzed 15 patients diagnosed with parotid IH from 2009 to 2016 who were cared for at a tertiary care center. Demographic information, lesion characteristics, and treatment course were obtained through patient chart review. Results: Fifteen pediatric patients with parotid IH were evaluated. The female:male ratio was 4:1; the average age of diagnosis was 8.75 months. Most lesions were greater than 3 cm in their widest dimension (73.3%), and 13 patients underwent imaging to further clarify the parotid mass in their clinical workup. Fourteen patients began treatment with propranolol; 10 patients saw complete resolution of their IH (66.7%) and 3 had a partial response to β-blocker therapy (20%). After discontinuation of propranolol, 2 patients had regrowth 2 to 3 months later after regression and were restarted on therapy. The average duration of treatment was 9.9 ± 8.45 months. The known adverse effects of propranolol—hypoglycemia, hypotension, bradycardia, and bronchospasm—were not observed in any patient. Conclusion: In the treatment of parotid IH, propranolol is the generally accepted first-line therapy, as compared to corticosteroid or interferon α injections of years past. Parotid hemangiomas, however, have a lower response rate to propranolol and a similar recurrence rate compared to IH at other sites. The treatment duration necessary tends to be longer. Future studies will aim at identifying and evaluating potential predictors of outcomes to help inform the management of parotid hemangiomas.

Authors: Sreenivas V. , Sima Natashya H. , Philip Sumy 
Published: September 2019

Purpose: To assess the correlation between the comorbidities, such as hypertension, diabetes, thyroid disorders, hearing loss, hyperlipidemia, and vitamin D deficiency and benign paroxysmal positional vertigo (BPPV) and to determine the high-risk groups for recurrence of symptoms. Design: Descriptive analytical study. Materials and Methods: Patients who met the inclusion criteria underwent complete ear, nose, and throat examination, including Dix-Hallpike test and roll-over test and blood pressure recording. Investigations included pure tone audiometry, random blood sugar/fasting blood sugar, serum thyroid-stimulating hormone, fasting serum total cholesterol, and serum vitamin D levels. Patients were followed up for a period of 6 months to 1 year. Results: Older age-group has an increased risk of BPPV and recurrence of symptoms. About 45.1% of the patients with BPPV who were detected to have symptoms of hypertension were also more common with hypertensive. Diabetes mellitus was found to have an increased risk of BPPV and its recurrence. The presence of other comorbidities, such as abnormal thyroid function test (9%), sensorineural hearing loss (14%), hypercholesterolemia (46%), and vitamin D deficiency (79%) didn’t show any significant risk for recurrence. Conclusion: The presence of comorbidities worsens the status of BPPV, causing more frequent otolith detachment. Hence, it increases the risk of recurrence even after successful repositioning maneuver. Patients presenting with BPPV should therefore be evaluated and treated for these comorbidities along with the repositioning maneuvers.

Published: September 2019

Objective To describe the clinical and radiological characteristics and outcomes of patients with aquaporin-4-immunoglobulin G (AQP4-IgG) seropositive neuromyelitis optica spectrum disorder (NMOSD) coexisting with systemic lupus erythematosus (SLE) and primary Sjögren's syndrome (pSS) in a single center. Methods We included patients with diagnosis of NMOSD and a concomitant diagnosis of SLE or pSS. Demographic, clinical, serological and imaging characteristics were retrieved from clinical charts. Results Twelve patients were included, of whom 11 (91.7%) were women. Seven (58.3%) had SLE and five (41.7%) pSS. In five (41.7%) patients NMOSD followed SLE/pSS onset, four (33.3%) patients had a simultaneous presentation, and in three (25%) NMOSD preceded pSS onset. The mean age at first neurological event was 39 years. Eleven patients (91.7%) experienced acute transverse myelitis/longitudinally extensive transverse myelitis, five (41.7%) optic neuritis, three (25%) a cerebral syndrome and two (16.7%) each area postrema syndrome, acute brainstem syndrome and cerebellar syndrome. Eleven (91.7%) patients went into either total or partial NMOSD remission at median follow-up of 89.5 months. Conclusion AQP4-IgG seropositive NMOSD arose in the context of quiescent SLE and pSS with extraglandular features. As NMOSD coexisting with SLE/pSS is rare, collaborative multicenter studies are needed to clarify the natural history and outcomes of this overlap syndrome.

Published: September 2019

Introduction Chemotherapies are handled using Good Manufacturing Practices, which ensure asepsis and high-quality production. Continuous education is compulsory and usually includes theoretical and practical exercises. Objectives This work aimed to validate an innovative method of teaching good manufacturing practices based on an escape room mixing simulation and gaming. Method Pairs of learners were locked in a simulated clean room (Esclean Room) and had 1 hour to produce a chemotherapy and escape by finding solutions to 23 “Good Manufacturing Practices mysteries” linked to combination locks. To measure the experiment’s impact on teaching, questionnaires including the 23 mysteries (in different orders) were filled in before, just after and one month after escape from the Esclean Room. Pharmacy staff’ degrees of certainty were noted for each question. A satisfaction survey was completed. Results Seventy-two learners (29% senior pharmacists, 14% junior pharmacists, and 57% pharmacy technicians) escaped the Esclean Room and 56 answered every questionnaire. The educational intervention resulted in increases in correct answers and certainty. Correct answers rose from 57% in the first questionnaire to 80% in the third ( p < 0.001). Certainty scores rose from 50% before the experiment to 70% one month afterwards ( p < 0.001). Despite 68% of learners having never taken part in an escape room game before, 79% liked this educational method. Conclusion This study built and tested a pedagogical escape room involving a high risk, professional, pharmacy process. The use of this pharmacy technology simulation had a positive impact on pharmacy staff theoretical knowledge.

Published: September 2019

Background Medication errors can lead to preventable adverse drug events and associated hospitalization and healthcare cost to patients. Pharmacotherapy in patients with hematologic malignancies is more complex than that in general medicine patients. This study evaluated the clinical and economic impact of clinical pharmacist intervention in a hematology unit. Methods This retrospective study compared the number of pharmacist interventions and the economic impact for one year before and after a clinical pharmacist was deployed in a hematology unit. The clinical pharmacist joined the ward rounds and gave patient counseling and recommendations on medication use. For pharmacist intervention analysis, we compared the number and type of interventions. For cost analysis, we calculated the cost savings, estimated the cost avoidance, and compared the benefit–cost ratio between the two periods. Results The average length of hospitalization reduced from 19.27 days to 16.69 days after clinical pharmacist deployment. The rate of pharmacist interventions in medication orders increased from 143 out of 42,501 prescriptions (0.34%) to 826 out of 44,175 prescriptions (1.87%) (P < 0.00001). The calculated cost savings (NT$37,080 and NT$252,280), cost avoidance (NT$582,100 and NT$2,304,600), and benefit–cost ratio (0.77 and 3.19) increased after clinical pharmacist deployment. Conclusion This study demonstrated that the number of interventions significantly increased after clinical pharmacist deployment. This service could reduce medication errors, preventable adverse drug events, and costs of both medications and potential adverse drug events.
