Role of Duodenal Bulb Biopsy in Diagnosing Suspected Celiac Disease in Adult Patients: A Systematic Review and Meta-analysis.

BACKGROUND AND AIMS: Current guidelines recommend multiple biopsies from the first (D1) and second (D2) part of duodenum to establish a diagnosis of celiac disease. In this meta-analysis we aimed to find whether D1 biopsy can increase the diagnostic yield of adult celiac disease. METHODS: Literature databases were searched until January 2023 for studies reporting diagnosis of celiac disease in the adult population using D1 biopsy. Meta-analysis was done using a random-effects model. Heterogeneity was assessed by I2% and 95% prediction interval statistics. Measured outcomes were diagnostic yield with D1 and D2 biopsies and from 4 versus 2 biopsy samples. RESULTS: A total of 16 studies were included in the final analysis. The pooled diagnostic rate of celiac disease from D1 biopsy was 77.4% [95% CI (64.7-86.5, I2 94%)] and from D2 biopsy was 75.3% [60.8-85.7, I2 96%]. The pooled rate of increase in diagnostic yield with D1 biopsy was 6.9% I [4.6-10.2, I2 66%]. The pooled diagnosis rate with 2 biopsy samples were 77.3% [50-92, I2 93%] and 86.4% I [58.4-96.7, I2 87%] from D1 and D2 respectively, whereas that with 4 biopsy samples were 83.3% [49.8-96.2, I2 76%] and 70.5% I [51-84.6, I2 96%] from D1 and D2, respectively, the difference being non-significant. CONCLUSION: Our study demonstrates that taking 4 biopsy samples does not incur any additional diagnostic value over taking 2 biopsy samples from each duodenum segment. Although biopsy from the D1 and D2 has similar diagnostic yield in the adult population, there was an overall increase in diagnostic yield with D1 biopsy, especially in those with a patchy disease distribution.

A red herring colonization of Mycobacterium lentiflavum in cutaneous sporotrichosis lesions misleading the diagnosis.

A 42-year-old man presented with a sporotrichoid lymphocutaneous infection for 1 month. The histopathology of the lesions showed numerous intracellular mycobacteria within foamy histiocytes suggestive of nontuberculous mycobacteria and misled the empiric treatment. The final culture grew Sporothrix spp. and the lesions improved with antifungal treatment alone. This case report depicts a case of Mycobacterium lentiflavum colonization in cutaneous sporotrichosis lesions on histopathology to raise awareness among physicians about this rare coincidence that could mislead the diagnosis.

Antiplatelet therapy associated with lower prevalence of advanced liver fibrosis in non-alcoholic fatty liver disease: A systematic review and meta-analysis.

Despite the growing disease burden of non-alcoholic fatty liver disease (NAFLD), approved medical treatments to improve or prevent liver fibrosis are effective only in a small number of patients. Recent studies have found the new use of antiplatelet agents for antifibrotic benefits in NAFLD, but human studies are still limited. The goal of this meta-analysis was to combine the findings of existing relevant studies to investigate the effects of antiplatelet therapy in reducing or preventing advanced liver fibrosis in patients with NAFLD. We conducted a systematic literature search in PubMed, EMBASE, and Web of Science databases from inception to January 2021 to identify all original studies that investigated the use of antiplatelet agents in patients with NAFLD. We used the National Institutes of Health's quality assessment tool for observational cohort and cross-sectional studies to assess study quality and risk of bias. The primary outcome was the prevalence of advanced liver fibrosis stage 3-4. Data from each study was combined using the random-effects, generic inverse variance method of DerSimonian and Laird to calculate pooled odds ratio (OR) and 95% confidence intervals (CIs). Of the 2,498 studies identified, 4 studies involving 2,593 patients with NAFLD were included in this study (949 antiplatelet agent users and 1,644 non-antiplatelet agent users). The use of aspirin and/or P2Y12 receptor inhibitors was associated with a lower pooled OR of advanced liver fibrosis in patients with NAFLD (pooled OR = 0.66; 95% CI: 0.53-0.81, I2 = 0.0%; p < 0.001). This study focuses on the outcome of advanced liver fibrosis in patients with NAFLD. Our study is limited by the small number of studies that were included. Preliminary evidence from this meta-analysis suggests a protective association between antiplatelet therapy and the prevalence of advanced liver fibrosis in patients with NAFLD. Our findings support future research into repositioning an antiplatelet agent as a novel NAFLD treatment.

Upper gastrointestinal bleeding as the initial manifestation of gastroenteropancreatic neuroendocrine tumors.

A 78-year-old man presented with upper gastrointestinal bleeding, which was biopsy proven to be from a gastric neuroendocrine tumor. By the time of diagnosis, he developed liver metastasis and died 2 months later. Upper gastrointestinal bleeding is an uncommon feature in gastroenteropancreatic neuroendocrine tumor.

Intestinal angioedema caused by an acquired C1 esterase inhibitor deficiency associated with underlying splenic marginal zone lymphoma.

A 75-year-old woman presented with recurrent abdominal pain and vomiting for 1 year and was later found to have splenomegaly and pancytopenia. This case report depicts a clinical picture of intestinal angioedema, a challenging diagnosis, and an underlying rare syndrome of acquired C1 esterase inhibitor deficiency associated with splenic marginal zone lymphoma.

Atypical Presentation of Fatal Disease: Painless Aortic Dissection.

Aortic dissections (ADs) are uncommon but they are highly lethal. Due to atypical signs and symptoms, diagnosis of type B AD can be easily missed or delayed. Our patient presented to the emergency center with dizziness and fall for which he was evaluated and treated for hypertension. Two weeks later, he again presented to the hospital with painless right groin swelling: computed tomography (CT) of the abdomen incidentally showed type B AD. The patient might have an AD presenting with dizziness and hypertension during previous presentation. From this case, we learn how it is challenging to diagnose painless AD especially when patient comes with atypical symptoms. In high-risk patients with unexplained dizziness and fall, a high degree of suspicion may help for early diagnosis and management.

Intervening alcohol marketing to reduce harmful alcohol use and lessons learned from the theory of changes: Case studies in Thailand.

Objectives: Globally, the burden of disease caused by alcohol use has been steadily increasing, including in Thailand. In this study, we aim to test the effectiveness of Anderson et al.'s suggested three approaches to change the collective social norms, which comprise of: (1) providing information and an understanding about alcohol use behaviour, its causes and distribution; (2) focusing strategies on groups rather than individuals; and (3) strengthening supportive laws, regulations and approaches. Study design: We employed a mixed-methods approach. Evidence was gathered from literature review and in-depth interviews with key individuals who are responsible for community-based interventions to alcohol marketing strategies in Thailand. Methods: We chose to focus on two case studies in Nan and Surin provinces, where hospital-based longitudinal data (8 years) were available. Changes in casualties related to the harmful use of alcohol, resulting from interactions between community-based interventions and alcohol marketing during the time of annual festivals were investigated. We employed the theory of change (ToC) defined by Vogel to guide the data collection and analysis. We reviewed literature from online databases and grey literature to generate causal-loop diagrams. Results: We created a causal-loop diagram to describe the complexity of harmful alcohol use, its related factors, context, interventions and outcomes. Over the decade between 2006 and 2015, community-based strategies led to a substantial reduction of casualties (initially a 50% reduction, rising to an 80-90% reduction by the end of the study period) during the time of the festivals. Conclusions: The reduction in injuries and fatalities could be a result of the concerted actions, including legal sanctions of alcohol beverage sales and advertisement, and public education to raise awareness and impart knowledge of the harmful use of alcohol. The actions were organised by a coalition of civil society, health professionals, public authorities and community leaders using hospital-based data on the adverse effects of harmful alcohol use to mobilise political support at the provincial level. The availability of long-term financial support as a catalytic source of funds and the presence of a comprehensive alcohol control act enabled framing and mobilisation of local resources and political support.

Paradox of sustainability in tobacco control in Thailand: A comprehensive assessment of three-decade experiences.

BACKGROUND: Over the past 3 decades of tobacco control, Thailand has gained international recognition as a middle-income country with sustained achievement of declining smoking prevalence. However, the number of key Framework Convention on Tobacco Control measures implementation is still far away from the highest-level implementation. As a result, we aim to explore explanatory factors for the paradoxical phenomenon of sustainability in tobacco control in Thailand, to understand what the paradox means, why it happens, and how to take further steps in minimizing the paradox. METHODS: We used a mixed-method approach comprising qualitative (review of literature and documents plus Program Sustainability Assessment Tool [PSAT] guided key informant interviews) and semi-quantitative methods (PSAT scoring, Theory of Change [TOC], and causal-loop diagram [CLD]) to synthesize all the findings from the qualitative data. RESULTS: Across all eight domains, sustainability scores at the local level are lower than the national level. The highest total score was in three domains: political support, partnership, and organizational capacity. The lowest total score was for the strategic planning domain. We propose a set of key strategic elements and drivers for future strategic planning. DISCUSSION: Using CLD, we capture a high-level view of tobacco control with dynamic interactions between contexts, mechanisms, interventions, and outcomes. We believe the deep understanding of tobacco control and the proposed strategy to counteract transnational tobacco companies in Thailand will guide future sustainable actions to reduce the prevalence of smoking, especially in the strategic planning domain that has the lowest PSAT score.

Pica/Pagophagia-Associated Hyponatremia: Patient Presenting With Seizure.

Pica is an unusual condition in which patients crave and chew substances with no nutritional value. Ice pica (pagophagia) is commonly seen in patient with iron deficiency. People chew ice cubes or add ice to their drinks to cool or refresh themselves, and they may not consider this as an abnormal behavior. Excessive ice chewing/eating can have significant health risks, including electrolyte abnormalities and metabolic disorders. We report a patient admitted to our hospital with severe hyponatremia and seizures due to iron deficiency-associated pagophagia. Ice pica leading to hyponatremia and seizure is not commonly seen in clinical practice. It was a challenging case and the patient was seen and investigated at outpatient clinic for polyuria, though an underlying cause was not identified. Patients may be secretive or reluctant to mention their pica habit. Studies have also shown that most physicians are unaware of pica and most cases can be easily missed.

Marijuana use-induced spontaneous pneumomediastinum.

The presence of air in the mediastinum is a rare finding called pneumomediastinum. Spontaneous pneumomediastinum is typically benign. Marijuana use has been rarely reported to cause pneumomediastinum. Our case series presents two young men with no significant past medical history who had a history of marijuana use and developed pneumomediastinum after multiple episodes of intractable vomiting. The pathophysiology of spontaneous pneumomediastinum in marijuana users includes cyclic vomiting or microperforation of the esophagus or barotrauma during breathing maneuvers. Most cases can be managed conservatively.

Sinus of Valsalva aneurysm presenting with chest pain.

Sinus of Valsalva aneurysm is a rare aortic root defect that can be dangerous due to its serious complications. It is defined as dilatation of one or more of the aortic valve sinuses. It is usually asymptomatic, and patients rarely present with chest pain, arrhythmias, or heart failure. We report a 29-year-old man who presented with atypical chest pain of 8 months with a normal cardiovascular exam. His laboratory work was unremarkable. Transthoracic echocardiography and transesophageal echocardiography showed a calcified sinus of Valsalva aneurysm arising from the noncoronary cusp. The patient underwent aneurysm repair surgery with no complications, and his chest pain resolved.

Assessment of nationwide emergency systems in Thailand, a middle-income country setting with UHC.

BACKGROUND: Evidence has been limited regarding broader emergency systems assessment in low- and middle-income countries. The aim of the present study was to provide the empirical evidence of Thai emergency department (ED) workforce vis-à-vis workload on a national scale, the availability of services for selected high-priority health burdens, and the governance obstacles in addressing the workforce management. METHOD: One hundred thirty public Thai EDs that provide 24-hour emergency medical care were identified across Thailand as meeting the inclusion criteria. The mailed questionnaires were administered to collect data related to the objectives of the research study. RESULT: Responses were received from 91 of 130 (70%) hospitals. The median number of patients visiting hospital EDs was 51 221 per year with 32.8% considered nonurgent (ESI levels 4-5). University hospital EDs were staffed with a higher number of ER professionals than EDs of service-based secondary care and tertiary care hospitals under Ministry of Public Health (MOPH). Almost all hospitals expressed concerns about the deficiency of doctors and nurses especially emergency physician (EP) and emergency nurses. The percentage of hospitals reporting the availability of coronary artery catheterization (34%) and thrombolytic infusion for acute thrombotic stroke (24%) was limited. The governance obstacles to manage emergency systems were considered. CONCLUSION: ED staffing seems to positively correlate with workloads except university hospitals, in our study, which may suggest the influence of teaching status on the allocation of the human resource. Among the governance obstacles in ED management, a better response to nonurgent patients requires flexibility for hospitals to set financial disincentives or mobilization and management of human resources.

Relevance of using length of stay as a key indicator to monitor emergency department performance: Case study from a rural hospital in Thailand.

OBJECTIVE: The present study explores factors related to length of stay (LOS) in a rural public hospital in Thailand and assesses the feasibility of using LOS as an ED key performance indicator. METHODS: Using a mixed-methods approach, qualitative methods (in-depth interviews, patients' chart review and participatory observations) were used to guide and elaborate findings from quantitative analysis of 555 electronic ED records. RESULTS: Multivariate analysis revealed that age, Emergency Severity Index score and number of laboratory tests were significantly associated with LOS. The qualitative approach provided contradicting evidence on the linkage between LOS and patient outcomes. On the one hand, considering the 4 h rule, a child with asthma was referred to a tertiary care hospital because of deterioration after 4 h of ED care. On the other hand, a woman with sepsis was hospitalised with improved condition despite 7 h of ED care. Interviews revealed the waiting time to see doctors was probably the top priority issue for patients. CONCLUSIONS: Factors related to LOS in a rural hospital in Thailand are similar and in contrast to those of a previous study in a medical school setting. Reasons for the discrepancy of findings and implications for improving ED services were discussed. Our data support the notion of controversy in using LOS as a key indicator of ED performance in this rural hospital setting. Thus, it is imperative to not rely on any single throughput or process indicators to monitor ED performance, but to take into account a set of indicators including patient outcomes.

Closing the Equity Gap of Access to Emergency Departments of Private Hospitals in Thailand.

BACKGROUND: Previous policy implementation in 2012 to incentivize private hospitals in Thailand, a country with universal health coverage, to provide free-of-charge emergency care using DRG-based payment resulted in an equity gap of access and copayment. To bridge the gap, strategic policies involving financial and legal interventions were implemented in 2017. This study aims to assess whether this new approach would be able to fill the gap. METHODS: We analyzed an administrative dataset of over 20,206 patients visiting private hospital EDs from April 2017 to October 2017 requested for the preauthorization of access to emergency care in the first 72 hours free of charge. The association between types of insurance and the approval status was explored using logistic regression equation adjusting for age, modes of access, systolic blood pressure, respiratory rate, and Glasgow coma scores. RESULTS AND DISCUSSION: The strategic policies implementation resulted in reversing ED payer mix from the most privileged scheme, having the major share of ED visit, to the least privileged scheme. The data showed an increasing trend of ED visits to private hospitals indicates the acceptance of the financial incentive. Obvious differences in degrees of urgency between authorized and unauthorized patients suggested the role of preauthorization as a barrier to the noncritical patient visiting the ED. Furthermore, our study depicted the gender disparity between authorized and unauthorized patients which might indicate a delay in care seeking among critical female patients. Lessons learned for policymakers in low-and-middle income countries attempting to close the equity gap of access to private hospital EDs are discussed.

Payment Reforms for Prehospital Care Services in a Middle Income Country: Assessing Implementation and Patient Outcomes Using a Mixed-Methods Approach.

INTRODUCTION: Financing health systems constitutes a key element of well-functioning healthcare system. Prior to 2015, two new financial arrangements (direct-pay and E-claim systems) were introduced on a voluntary basis which aimed to pool more financial resources and improve cash flow of prehospital care systems. The aims of this study were to (1) assess the effects of direct-pay system in terms of (a) timeliness of reimbursement to EMS agencies, (b) changes in clinical care processes, and (c) the outcomes of patient care as compared to previous system; (2) identify the reasons for or against EMS agencies to participate in direct-pay system mechanisms; (3) identify the emerging issues with potential to significantly further the advancement of EMS systems. Using a mixed-methods approach, retrospective datasets of 3,769,399 individual records of call responses from 2015 to 2017 were analyzed which compared EMS units with the direct-pay system against those without in terms of time flow of claim data and patient outcomes. For qualitative data, in-depth interviews were conducted. RESULTS: EMS units participating in both systems had the highest percentages of financial claim being made in time as compared to those not participating in any (p=0.012). However, there were not any practically meaningful differences between EMS units participating and not participating in either of the payment systems in terms of patient care such as appropriateness of response time, airway management, and outcome of treatment. Analysis of data from focus-group and individual interviews ended up with a causal loop diagram demonstrating potential explanatory mechanisms for those findings. CONCLUSION: It is evident that progress has been made in terms of mobilising more financial inputs and improving financial information flow. However, there is no evidence of any changes in patient outcomes and quality of care. Furthermore, whether the progress is meaningful in filling the gaps of financial demands of the prehospital care systems is still questionable. Room for future improvement of prehospital care systems was discussed with implications for other countries.
