Impact of Telemedicine on Patient Satisfaction and Perceptions of Care Quality in Radiation Oncology.

BACKGROUND: The COVID-19 pandemic has transformed cancer care with the rapid expansion of telemedicine, but given the limited use of telemedicine in oncology, concerns have been raised about the quality of care being delivered. We assessed the patient experience with telemedicine in routine radiation oncology practice to determine satisfaction, quality of care, and opportunities for optimization. PATIENTS AND METHODS: Patients seen within a multistate comprehensive cancer center for prepandemic office visits and intrapandemic telemedicine visits in December 2019 through June 2020 who completed patient experience questionnaires were evaluated. Patient satisfaction between office and telemedicine consultations were compared, patient visit-type preferences were assessed, and factors associated with an office visit preference were determined. RESULTS: In total, 1,077 patients were assessed (office visit, n=726; telemedicine, n=351). The telemedicine-consult survey response rate was 40%. No significant differences were seen in satisfaction scores between office and telemedicine consultations, including the appointment experience versus expectation, quality of physician's explanation, and level of physician concern and friendliness. Among telemedicine survey respondents, 45% and 34% preferred telemedicine and office visits, respectively, and 21% had no preference for their visit type. Most respondents found their confidence in their physician (90%), understanding of the treatment plan (88%), and confidence in their treatment (87%) to be better or no different than with an office visit. Patients with better performance status and who were married/partnered were more likely to prefer in-person office visit consultations (odds ratio [OR], 1.04 [95% CI, 1.00-1.08]; P=.047, and 2.41 [95% CI, 1.14-5.47]; P=.009, respectively). Patients with telephone-only encounters were more likely to report better treatment plan understanding with an office visit (OR, 2.25; 95% CI, 1.00-4.77; P=.04). CONCLUSIONS: This study is the first to assess telemedicine in routine radiation oncology practice, and found high patient satisfaction and confidence in their care. Optimization of telemedicine in oncology should be a priority, specifically access to audiovisual capabilities that can improve patient-oncologist communication.

A decade of research on the 17q12-21 asthma locus: Piecing together the puzzle.

Chromosome 17q12-21 remains the most highly replicated and significant asthma locus. Genotypes in the core region defined by the first genome-wide association study correlate with expression of 2 genes, ORM1-like 3 (ORMDL3) and gasdermin B (GSDMB), making these prime candidate asthma genes, although recent studies have implicated gasdermin A (GSDMA) distal to and post-GPI attachment to proteins 3 (PGAP3) proximal to the core region as independent loci. We review 10 years of studies on the 17q12-21 locus and suggest that genotype-specific risks for asthma at the proximal and distal loci are not specific to early-onset asthma and mediated by PGAP3, ORMDL3, and/or GSDMA expression. We propose that the weak and inconsistent associations of 17q single nucleotide polymorphisms with asthma in African Americans is due to the high frequency of some 17q alleles, the breakdown of linkage disequilibrium on African-derived chromosomes, and possibly different early-life asthma endotypes in these children. Finally, the inconsistent association between asthma and gene expression levels in blood or lung cells from older children and adults suggests that genotype effects may mediate asthma risk or protection during critical developmental windows and/or in response to relevant exposures in early life. Thus studies of young children and ethnically diverse populations are required to fully understand the relationship between genotype and asthma phenotype and the gene regulatory architecture at this locus.

Optimization of Morpholino Antisense Oligonucleotides Targeting the Intronic Repressor Element1 in Spinal Muscular Atrophy.

Loss of Survival Motor Neuron-1 (SMN1) causes Spinal Muscular Atrophy, a devastating neurodegenerative disease. SMN2 is a nearly identical copy gene; however SMN2 cannot prevent disease development in the absence of SMN1 since the majority of SMN2-derived transcripts are alternatively spliced, encoding a truncated, unstable protein lacking exon 7. Nevertheless, SMN2 retains the ability to produce low levels of functional protein. Previously we have described a splice-switching Morpholino antisense oligonucleotide (ASO) sequence that targets a potent intronic repressor, Element1 (E1), located upstream of SMN2 exon 7. In this study, we have assessed a novel panel of Morpholino ASOs with the goal of optimizing E1 ASO activity. Screening for efficacy in the SMNΔ7 mouse model, a single ASO variant was more active in vivo compared with the original E1(MO)-ASO. Sequence variant eleven (E1(MOv11)) consistently showed greater efficacy by increasing the lifespan of severe Spinal Muscular Atrophy mice after a single intracerebroventricular injection in the central nervous system, exhibited a strong dose-response across an order of magnitude, and demonstrated excellent target engagement by partially reversing the pathogenic SMN2 splicing event. We conclude that Morpholino modified ASOs are effective in modifying SMN2 splicing and have the potential for future Spinal Muscular Atrophy clinical applications.

Disparity in Patients' Self-Reported and Charted Medication Allergy Information.

OBJECTIVES: The objective of this study was to compare current adverse drug/allergy reaction reporting in patient electronic medical records/charts against information gathered during patient interviews in the emergency department. Our hypothesis was that current methods for allergy reporting results in significant discrepancy between what is documented and the actual allergy history upon interviewing the patient. METHODS: The study was conducted between December 2011 and April 2012 in an academic emergency department. This was a convenience sample study comparing a prospective patient interview with previously documented allergy histories. Demographics for sex, age, and race were recorded. Patients to be interviewed were adults with at least one documented allergy in their chart. Descriptive statistics and percentages were used for demographic and prevalence data. Agreement between interviews and charts was assessed for both the reaction type and the reaction descriptor. RESULTS: There were 101 patients interviewed during this 4-month period, and a total of 235 adverse drug reactions were recorded. There were 66 women and 35 men included in this study. The mean age was 51 ± 17 years. The median number of allergy instances for women was 2 (interquartile range 1-3) and for men the median number of allergy instances was 1 (interquartile range 1-2). The percentage of agreements for overall allergies was 85% and 50% for the type of reaction. Total profile agreement occurred in nine patients. CONCLUSIONS: The percentage of agreement between interviews and charting for reaction type was 50%. Even with the use of electronic medical records, better methods are needed to properly record allergies to ensure patient safety and care.

Insurance Denials and Patient Treatment in a Large Academic Radiation Oncology Center.

Importance: Insurance barriers to cancer care can cause significant patient and clinician burden. Objective: To investigate the association of insurance denial with changes in technique, dose, and time to delivery of radiation oncology treatment. Design, Setting, and Participants: In this single-institution cohort analysis, data were collected from patients with payer-denied authorization for radiation therapy (RT) from November 1, 2021, to December 8, 2022. Data were analyzed from December 15, 2022, to December 31, 2023. Exposure: Insurance denial for RT. Main Outcomes and Measures: Association of these denials with changes in RT technique, dose, and time to treatment delivery was assessed using χ2 tests. Results: A total of 206 cases (118 women [57.3%]; median age, 58 [range, 26-91] years) were identified. Most insurers (199 [96.6%]) were commercial payers, while 7 (3.4%) were Medicare or Medicare Advantage. One hundred sixty-one patients (78.2%) were younger than 65 years. Of 206 cases, 127 (61.7%) were ultimately authorized without any change to the requested RT technique or prescription dose; 56 (27.2%) were authorized after modification to RT technique and/or prescription dose required by the payer. Of 21 cases with required prescription dose change, the median decrease in dose was 24.0 (range, 2.3-51.0) Gy. Of 202 cases (98.1%) with RT delivered, 72 (34.9%) were delayed for a mean (SD) of 7.8 (9.1) days and median of 5 (range, 1-49) days. Four cases (1.9%) ultimately did not receive any authorization, with 3 (1.5%) not undergoing RT, and 1 (0.5%) seeking treatment at another institution. Conclusions and Relevance: In this cohort study of patients with payer-denied cases, most insurance denials in radiation oncology were ultimately approved on appeal; however, RT technique and/or effectiveness may be compromised by payer-mandated changes. Further investigation and action to recognize the time and financial burdens on clinicians and clinical effects on patients caused by insurance denials of RT is needed.

Prospective Clinical Evaluation of Integrating a Radiation Anatomist for Contouring in Routine Radiation Treatment Planning.

Purpose: A radiation anatomist was trained and integrated into clinical practice at a multi-site academic center. The primary objective of this quality improvement study was to determine whether a radiation anatomist improves the quality of organ-at-risk (OAR) contours, and secondarily to determine the impact on efficiency in the treatment planning process. Methods and Materials: From March to August 2020, all patients undergoing computed tomography-based radiation planning at 2 clinics at Memorial Sloan Kettering Cancer Center were assigned using an "every other" process to either (1) OAR contouring by a radiation anatomist (intervention) or (2) contouring by the treating physician (standard of care). Blinded dosimetrists reported OAR contour quality using a 3-point scoring system based on a common clinical trial protocol deviation scale (1, acceptable; 2, minor deviation; and 3, major deviation). Physicians reported time spent contouring for all cases. Analyses included the Fisher exact test and multivariable ordinal logistic regression. Results: There were 249 cases with data available for the primary endpoint (66% response rate). The mean OAR quality rating was 1.1 ± 0.4 for the intervention group and 1.4 ± 0.7 for the standard of care group (P < .001), with subset analysis showing a significant difference for gastrointestinal cases (n = 49; P <.001). Time from simulation to contour approval was reduced from 3 days (interquartile range [IQR], 1-6 days) in the control group to 2 days (IQR, 1-5 days) in the intervention group (P = .007). Both physicians and dosimetrists self-reported decreased time spent contouring in the intervention group compared with the control group, with a decreases of 8 minutes (17%; P < .001) and 5 minutes (50%; P = .002), respectively. Qualitative comments most often indicated edits required to bowel contours (n = 14). Conclusions: These findings support improvements in both OAR contour quality and workflow efficiency with implementation of a radiation anatomist in routine practice. Findings could also inform development of autosegmentation by identifying disease sites and specific OARs contributing to low clinical efficiency. Future research is needed to determine the potential effect of reduced physician time spent contouring OARs on burnout.

African-specific alleles modify risk for asthma at the 17q12-q21 locus in African Americans.

BACKGROUND: Asthma is the most common chronic disease in children, occurring at higher frequencies and with more severe disease in children with African ancestry. METHODS: We tested for association with haplotypes at the most replicated and significant childhood-onset asthma locus at 17q12-q21 and asthma in European American and African American children. Following this, we used whole-genome sequencing data from 1060 African American and 100 European American individuals to identify novel variants on a high-risk African American-specific haplotype. We characterized these variants in silico using gene expression and ATAC-seq data from airway epithelial cells, functional annotations from ENCODE, and promoter capture (pc)Hi-C maps in airway epithelial cells. Candidate causal variants were then assessed for correlation with asthma-associated phenotypes in African American children and adults. RESULTS: Our studies revealed nine novel African-specific common variants, enriched on a high-risk asthma haplotype, which regulated the expression of GSDMA in airway epithelial cells and were associated with features of severe asthma. Using ENCODE annotations, ATAC-seq, and pcHi-C, we narrowed the associations to two candidate causal variants that are associated with features of T2 low severe asthma. CONCLUSIONS: Previously unknown genetic variation at the 17q12-21 childhood-onset asthma locus contributes to asthma severity in individuals with African ancestries. We suggest that many other population-specific variants that have not been discovered in GWAS contribute to the genetic risk for asthma and other common diseases.

Evaluation of the Abbott BinaxNOW COVID-19 Test Ag Card for rapid detection of SARS-CoV-2 infection by a local public health district with a rural population.

SARS-CoV-2 RT-PCR, the gold standard for diagnostic testing, may not be readily available or logistically applicable for routine COVID-19 testing in many rural communities in the United States. In this validation study, we compared the BinaxNOW™ COVID-19 Test Ag Card with SARS-CoV-2 RT-PCR in 214 participants who sought COVID-19 testing from a local public health district in Idaho, USA. The median age of participants was 35 and 82.7% were symptomatic. Thirty-seven participants (17.3%) had positive RT-PCR results. Results between the two tests were 94.4% concordant. The sensitivity of the BinaxNOW™ COVID-19 Test Ag Card was 67.6% (95% CI: 50.2-81.9%), and the specificity was 100.0% (95% CI: 97.9-100.0%). The positive predictive value (PPV) for the BinaxNOW™ COVID-19 Test Ag Card was 100.0% (95% CI: 86.2-100.0%), and the negative predictive value (NPV) was 93.6% (95% CI: 89.1-96.6%). Although the sensitivity of BinaxNOW™ COVID-19 Test Ag Card was lower than RT-PCR, rapid results and high specificity support its use for early detection of COVID-19, especially in settings where SARS-CoV-2 RT-PCR testing is not readily available. Rapid antigen tests, such as the BinaxNOW™ COVID-19 Test Ag Card, may be a more convenient tool in quickly identifying and preventing COVID-19 transmission, especially in rural settings.

Addressing Service Recovery Practice With Radiation Oncology Frontline Managers: A Project Brief.

The relationship between patient satisfaction, care compliance, and treatment outcomes suggests patients who report dissatisfaction perceive receipt of suboptimal care. Patient satisfaction plays a role in defining quality of care, affecting institutional reimbursement and reputation capital. Using an explanatory sequential mixed methodology approach, this study explored frontline management's role in effective service recovery, actively addressing instances of patient dissatisfaction to improve the overall patient experience. A survey of frontline managers, document and artifact reviews, and probing interviews identify the importance of consistent performance measurement, feedback, and frequent leadership training on the relevance and importance of service recovery.

Expression quantitative trait locus fine mapping of the 17q12-21 asthma locus in African American children: a genetic association and gene expression study.

BACKGROUND: African ancestry is associated with a higher prevalence and greater severity of asthma than European ancestries, yet genetic studies of the most common locus associated with childhood-onset asthma, 17q12-21, in African Americans have been inconclusive. The aim of this study was to leverage both the phenotyping of the Children's Respiratory and Environmental Workgroup (CREW) birth cohort consortium, and the reduced linkage disequilibrium in African Americans, to fine map the 17q12-21 locus. METHODS: We first did a genetic association study and meta-analysis using 17q12-21 tag single-nucleotide polymorphisms (SNPs) for childhood-onset asthma in 1613 European American and 870 African American children from the CREW consortium. Nine tag SNPs were selected based on linkage disequilibrium patterns at 17q12-21 and their association with asthma, considering the effect allele under an additive model (0, 1, or 2 effect alleles). Results were meta-analysed with publicly available summary data from the EVE consortium (on 4303 European American and 3034 African American individuals) for seven of the nine SNPs of interest. Subsequently, we tested for expression quantitative trait loci (eQTLs) among the SNPs associated with childhood-onset asthma and the expression of 17q12-21 genes in resting peripheral blood mononuclear cells (PBMCs) from 85 African American CREW children and in upper airway epithelial cells from 246 African American CREW children; and in lower airway epithelial cells from 44 European American and 72 African American adults from a case-control study of asthma genetic risk in Chicago (IL, USA). FINDINGS: 17q12-21 SNPs were broadly associated with asthma in European Americans. Only two SNPs (rs2305480 in gasdermin-B [GSDMB] and rs8076131 in ORMDL sphingolipid biosynthesis regulator 3 [ORMDL3]) were associated with asthma in African Americans, at a Bonferroni-corrected threshold of p<0·0055 (for rs2305480_G, odds ratio [OR] 1·36 [95% CI 1·12-1·65], p=0·0014; and for rs8076131_A, OR 1·37 [1·13-1·67], p=0·0010). In upper airway epithelial cells from African American children, genotype at rs2305480 was the most significant eQTL for GSDMB (eQTL effect size [ß] 1·35 [95% CI 1·25-1·46], p<0·0001), and to a lesser extent showed an eQTL effect for post-GPI attachment to proteins phospholipase 3 (ß 1·15 [1·08-1·22], p<0·0001). No SNPs were eQTLs for ORMDL3. By contrast, in PBMCs, the five core SNPs were associated only with expression of GSDMB and ORMDL3. Genotype at rs12936231 (in zona pellucida binding protein 2) showed the strongest associations across both genes (for GSDMB, eQTLß 1·24 [1·15-1·32], p<0·0001; and for ORMDL3 (ß 1·19 [1·12-1·24], p<0·0001). The eQTL effects of rs2305480 on GSDMB expression were replicated in lower airway cells from African American adults (ß 1·29 [1·15-1·44], p<0·0001). INTERPRETATION: Our study suggests that SNPs regulating GSDMB expression in airway epithelial cells have a major role in childhood-onset asthma, whereas SNPs regulating the expression levels of 17q12-21 genes in resting blood cells are not central to asthma risk. Our genetic and gene expression data in African Americans and European Americans indicated GSDMB to be the leading candidate gene at this important asthma locus.

The prevalence of HIV infection in women attending antenatal clinics in Fiji.

HIV (human immunodeficiency virus) is an increasing concern in the South Pacific. We estimate, based on reported figures, that the prevalence of HIV infection in women attending antenatal clinics in Fiji in 2003 was 0.04%. The number of children born to HIV-positive mothers is small, though perinatal transmission appears to be high. Fiji's preliminary strategies for prevention of perinatal transmission have been significant, but require ongoing support and implementation.

Analysis of Azithromycin Monohydrate as a Single or a Combinatorial Therapy in a Mouse Model of Severe Spinal Muscular Atrophy.

BACKGROUND: Spinal muscular atrophy (SMA) is a neurodegenerative autosomal recessive disorder characterized by the loss of α-motor neurons. A variety of molecular pathways are being investigated to elevate SMN protein expression in SMA models and in the clinic. One of these approaches involves stabilizing the SMNΔ7 protein by inducing translational read-through. Previous studies have demonstrated that functionality and stability are partially restored to the otherwise unstable SMNΔ7 by the addition of non-specific C-terminal peptide sequences, or by inducing a similar molecular event through the use of read-through inducing compounds such as aminoglycosides. OBJECTIVE: The objective was to determine the efficacy of the macrolide Azithromycin (AZM), an FDA approved read-through-inducing compound, in the well-established severe mouse model of SMA. METHODS: Initially, dosing regimen following ICV administrations of AZM at different post-natal days and concentrations was determined by their impact on SMN levels in disease-relevant tissues. Selected dose was then tested for phenotypic parameters changes as compared to the appropriate controls and in conjugation to another therapy. RESULTS: AZM increases SMN protein in disease relevant tissues, however, this did not translate into similar improvements in the SMA phenotype in a severe mouse model of SMA. Co-administration of AZM and a previously developed antisense oligonucleotide that increases SMN2 splicing, resulted in an improvement in the SMA phenotype beyond either AZM or ASO alone, including a highly significant extension in survival with improvement in body weight and movement. CONCLUSIONS: It is important to explore various approaches for SMA therapeutics, hence compounds that specifically induce SMNΔ7 read-through, without having prohibitive toxicity, may provide an alternative platform for a combinatorial treatment. Here we established that AZM activity at a low dose can increase SMN protein in disease-relevant animal model and can impact disease severity.

The relationship between educational preparation and performance on the ARRT examination in radiation therapy.

PURPOSE: To determine if graduates of different types of educational programs obtain similar scores on the Examination in Radiation Therapy administered by the American Registry of Radiologic Technologists. The results will help inform discussions regarding educational requirements for radiation therapists. METHODS AND MATERIALS: Test scores were obtained for 531 candidates who had taken the examination for the first time in 1997, 1998, or 1999. Candidates were divided into the following three categories, based on the type of educational program attended: hospital-based certificate, associate's degree, or bachelor's degree. To determine if test scores were related to the type of educational preparation, analyses of variance were conducted separately to test for differences in total scores and section scores, and scores on test questions intended to measure critical thinking skills. RESULTS: Candidates with an associate's degree scored slightly lower than candidates with a bachelor's degree on the total test (p < 0.10) and lower than candidates with either a certificate or bachelor's degree on Section B of the examination (Treatment Planning and Delivery, p < 0.10). Baccalaureate candidates did not obtain higher scores than those prepared in certificate programs. On critical thinking questions, candidates with certificates scored higher than those with associate's degrees (p < 0.10). Some evidence suggested that candidates with a certificate scored higher on critical thinking than those with a bachelor's degree (p < 0.10), and that candidates with a bachelor's degree scored higher than candidates with an associate's degree (p < 0.10). CONCLUSIONS: Although some of the differences in the mean test scores among the three educational groups were statistically significant, all differences were small and do not support one type of educational preparation over another.

The influence of educational preparation on evaluations of applicants for radiation therapy positions: a policy-capturing experiment.

PURPOSE: To determine whether radiation therapy department administrators prefer to hire graduates with certain types of educational preparation. The study was undertaken by the American Registry of Radiologic Technologists as part of a larger project to determine educational requirements for radiation therapists. METHODS AND MATERIALS: Forty-one department administrators evaluated applications from a pool of 984 hypothetical applicants for the position of radiation therapist. Applications were created by systematically varying eight characteristics such as years of experience, quality of educational program, and ratings from prior references. Type of educational program (baccalaureate degree, associate's degree, or hospital certificate) was of particular interest in this study. Each administrator evaluated 24 applications and assigned a rating ranging from 1 to 5 to indicate the extent to which he or she desired to interview each applicant. All ratings and applicant characteristics were coded and subjected to regression-type analyses to determine the relative importance of each applicant characteristic to administrators' decision-making policies. RESULTS: Information obtained from applicant references had the greatest impact on administrators' evaluations of applicant quality. Specifically, reference ratings of cooperation and technical skills were the two most important characteristics, followed closely by reference ratings of interpersonal skills and dependability. Quality of educational program had some influence, as did years of experience. Type of educational program had virtually no impact on interview decisions for a vast majority of the administrators. CONCLUSIONS: When making hiring decisions about hypothetical applicants, department administrators place most emphasis on evidence relating to past performance and give almost no weight to type of educational preparation. The extent to which these results generalize to actual applicants is addressed in the article.

Spatial clustering of filarial transmission before and after a Mass Drug Administration in a setting of low infection prevalence.

BACKGROUND: In the global program for the elimination of lymphatic filariasis (LF) longitudinal assessment of the prevalence of microfilaremia and antigenemia is recommended to monitor the effect of mass treatment on transmission. Additional monitoring tools such as entomologic and antibody methods may be useful in identifying residual foci of infection. In this study, we characterized serologic markers of infection and exposure spatially both before and after mass treatment, in an area of initial low Wuchereria bancrofti infection prevalence. METHODS: Consenting persons in the sentinel community were tested for circulating microfilaria and antigen (by immunochromatographic test) before and after the 1st annual mass drug administration of diethylcarbamazine and albendazole. A cohort of 161 persons provided serum specimens both years that were tested for antifilarial IgG (1 and 4) antibody. Every house was mapped using a differential Global Positioning System; this information was linked to the serologic data. W. bancrofti infection in the mosquito vector was assessed with year-round collection. Multiple linear regression was used to investigate the influence of antigen-positive persons on the antifilarial antibody responses of antigen-negative neighbors. RESULTS: After mass treatment, decreases were observed in the sentinel site in the overall prevalence of antigen (10.4% to 6.3%) and microfilaremia (0.9 to 0.4%). Of the persons in the cohort that provided serum specimens both years, 79% received treatment. Antigen prevalence decreased from 15.0% to 8.7%. Among 126 persons who received treatment, antigen and antifilarial IgG1 prevalence decreased significantly (p = 0.002 and 0.001, respectively). Among 34 persons who did not receive treatment, antifilarial IgG1 prevalence increased significantly (p = 0.003). Average antifilarial IgG1 levels decreased in households with high treatment coverage and increased in households that refused treatment. Each 10-meter increase in distance from the residence of a person who was antigen-positive in 2000 was associated a 4.68 unit decrease in antifilarial IgG1 level in 2001, controlling for other factors (p = 0.04). DISCUSSION: Antifilarial antibody assays can be used as a measure of filarial exposure. Our results suggest that micro-scale spatial heterogeneity exists in LF exposure and infection. Treatment appeared to be associated with reduced exposure at the sub-community level, suggesting the need to achieve high and homogeneous coverage. Public health messages should note the benefits of having one's neighbors receive treatment with antifilarial drugs.

A 5-year-old boy with miliary and osteoarticular tuberculosis.

Osteoarticular involvement is one manifestation of extrapulmonary tuberculosis (TB). We present a 5-year-old Burmese boy with 10 months of right hip pain and decreased range of motion. The patient also had low-grade fever, cough and decreased appetite. The patient was undocumented and had recently moved from Myanmar. He was thin, in moderate distress with bilateral lung rhonchi, mild subcostal retractions, low back pain, right hip tenderness and painful and limited right range of motion. The patient's chest and pelvis radiographs showed a miliary pattern and right acetabulum osteolytic lesions, respectively. He was started on anti-TB medication and cefotaxime. Ofloxacin was added because of the concern of drug-resistant TB. The patient underwent a right hip debridement. His symptoms improved markedly, with improved mobility. TB is a challenging infection to diagnose, which can cause significant delays in management.

A 9-year-old boy with severe diphtherial infection and cardiac complications.

The incidence of diphtheria has decreased since the introduction of an effective vaccine. However, in countries with low vaccination rates it has now become a re-emerging disease. Complications from diphtheria commonly include upper airway obstruction and cardiac complications. We present a 9-year-old boy who was diagnosed with diphtheria. He presented with fever, tonsilar plaques, respiratory failure and an incomplete vaccination history. He was endotracheal intubated and received diphtheria antitoxin and penicillin on the first day of hospitalisation. He developed progressive arrhythmias and fulminant myocarditis despite early identification and treatment with equine antitoxin and antibiotics. After a temporary transvenous pacemaker insertion due to third-degree atrioventricular block and hypotension for 1 week, he developed myocardial perforation from the pacemaker tip resulting in pericardial effusion. The treatment included emergency pericardiocentesis and pacemaker removal. His electrocardiogram showed a junctional rhythm with occasional premature ventricular complexes. He then developed ventricular tachycardia and cardiac arrest and finally died.

Trauma training course: innovative teaching models and methods for training health workers in active conflict zones of Eastern Myanmar.

BACKGROUND: Myanmar has struggled through decades of internal conflict, which has negatively impacted the country's health outcomes. Recent government changes have brought hope and reduced conflict. The ethnic minority groups have suffered the brunt of the health consequences and reside in regions that lack health infrastructure, resources, and providers. Due to the chronic lack of healthcare providers within conflict areas, health workers (HWs) have been trained in an effort to fill the void. Research has shown that these non-physician clinicians positively impact health outcomes in developing countries. These HWs are supported by community-based organizations in collaboration with foreign non-governmental organizations. Started in 2000, the trauma training course was developed to meet the educational needs of these HWs. METHODS: Essential procedures for HWs in conflict zones were identified, and teaching methods were adapted to develop models that were simple, reproducible, cost effective, and able to facilitate effective learning within the limitations of these challenging environments. This paper presents simulation models developed to teach trauma injury evaluation and management in resource-limited settings to HWs. RESULTS: Material and construction of the models described include breathing, chest, cricothyroidotomy, circulation, wound repair, fracture/dislocation, splinting, fasciotomy/amputation, and an animal model. In 2013, a pre/post test and post-training evaluation were completed, which demonstrated an increase in understanding of the material and satisfaction with the training. CONCLUSIONS: The simulation models described engage the HWs in clinical skills practice specific to injury management, which builds upon the HWs existing knowledge and facilitates an increased understanding of life-saving procedures. Through observation of the HW performance and HW feedback, these simulation models have increased the understanding of trauma management. Limitations include lack of a graduated learning system for the HWs, logistics, and time constraints. Despite the barriers faced, we feel that this is a necessary program that has reduced morbidity and mortality due to traumatic injury in the geographic areas that the HWs serve. With the changing political environment in Myanmar and the development of peace agreements between the government and the ethnic minority groups, these HWs can be integrated into Myanmar's evolving health system.

A 6-year-old boy with fever, rash and severe pneumonia.

The authors report a 6-year-old boy with fever, rash and cough. He was diagnosed with severe measles pneumonia and admitted to the paediatric intensive care unit with severe dyspnoea 8 days after symptom onset. He received intravenous antibiotics and high dose vitamin A. Three days later, he had recovered and was discharged home. He had not been vaccinated for measles, mumps and rubella according to the schedule. This case highlights the need for rapid diagnosis, appropriate treatment and determination of vaccination status of children with measles in order to prevent complications.
