Epidemiology and the Growing Epidemic of Food Allergy in Children and Adults Across the Globe.

PURPOSE OF REVIEW: Food allergies are immune-mediated, complex disorders, which are the source of increasing health concern worldwide. The goal of this review is to present an updated summary of the food allergy (FA) burden among children and adults across different populations, focusing on research from the past 5 years. RECENT FINDINGS: FAs impact a growing number of global residents-particularly those residing in higher-income, industrialized regions. Moreover, growing epidemiologic evidence suggests that the population health burden of non-IgE-mediated FAs, such as food protein-induced enterocolitis syndrome, may also be higher than previously reported. FA is a complex trait that impacts infants, children, as well as adults across the globe. The population health burden of both IgE- and non-IgE-mediated FAs is likely to grow in the absence of rapid advances and widespread implementation of effective FA prevention and treatment interventions. Systematic epidemiological research initiatives are needed, both nationally and globally, to better understand and reduce the burden of these allergic diseases.

Integrative medicine utilization among infertility patients.

BACKGROUND: Previous research suggests that some women are using integrative and complementary holistic approaches to optimize their own health and treat infertility. We aimed to determine patterns of integrative medicine use among those seeking fertility optimization by 1) Characterizing patterns of integrative medicine use to increase fertility; 2) Identifying demographic predictors associated with such integrative medicine use; and 3) Exploring cultural and religious influences on use of integrative medicine. METHODS: Cross-sectional self-reported survey data were collected from 1460 patients presenting to an academic fertility center in Chicago, Illinois. Variables were described with univariate frequencies and proportions, unadjusted bivariate comparisons were made between patient-level factors and reported integrative modality use, and multivariable logistic regression evaluated the strength of covariate-adjusted predictors of reported integrative medicine utilization. RESULTS: 80.4% of respondents reported using at least one integrative medicine modality to treat infertility (Acupuncture: 38.5%, Yoga: 27.6%, Massage: 25.8%, Meditation: 16.7%, and Herbal supplements: 18.5%). Diet therapy was the most frequently utilized modality (74.0%) followed by body therapy (45.2%), traditional alternative medicine (42.0%), mind therapy (32.1%), and senses therapy (23.0%). Any integrative medicine modality use was 4.03 times more likely among Hindu respondents compared to participants that identified as not religious (95% CI 1.2-13.7, p < 0.026). Significant differences in specific modality use were observed by race, religious affiliation, age, income, and insurance coverage. CONCLUSION: Most infertility patients in our study reported using at least one integrative medicine modality to help them conceive. Utilization was associated with age of participant, religious affiliation, annual income, and insurance coverage. Further research is needed to assess the impact of integrative medicine utilization on patient quality of life and outcomes.

Prevalence and burden of coconut allergy in the United States.

BACKGROUND: Epidemiologic data on coconut allergy remains sparse in the United States despite the labeling requirement by the Food Allergen Labeling and Consumer Protection Act for products containing coconut. OBJECTIVE: To provide current estimates of the prevalence, severity, determinants, and distribution of coconut allergy in the United States. METHODS: A comprehensive food allergy prevalence survey was administered to a nationally representative, probability-based sample of US households between October 1, 2015 and September 30, 2016. Eligible respondents included adults who were able to complete self- and parent-proxy report surveys in English or Spanish by means of web or phone. RESULTS: Using survey responses from 78,851 individuals, 0.39% (95% confidence interval [CI], 0.33-0.45) of the US general population were categorized as having convincing coconut allergy. Among children, 0.22% (95% CI, 0.16-0.30) were estimated to have coconut allergy compared with 0.43% (95% CI, 0.37-0.51) of adults, whereas only 0.12% (95% CI, 0.08-0.18) of these children and 0.20% (95% CI, 0.16-0.24) of adults with convincing immunoglobulin E (IgE)-mediated coconut allergy reported physician-confirmed diagnoses. A current epinephrine prescription was reported by 40.1% (95% CI, 33.3-47.4) of those with convincing coconut allergy. Reactions involving multiple organ systems were reported by 47.5% (95% CI, 40.1-54.9) of those with convincing coconut allergy. CONCLUSION: Roughly 1 in 260 Americans report symptoms consistent with an IgE-mediated allergy to coconut, although fewer than half of these individuals report receiving a physician diagnosis. Our data indicate that most individuals with reported coconut allergy meeting symptom-based criteria for convincingly IgE-mediated disease have comorbid FAs, and for many patients, clinical management seems to be suboptimal.

Accelerating Food Allergy Research: Need for a Data Commons.

Food allergy is a significant health problem affecting approximately 8% of children and 11% of adults in the United States. It exhibits all the characteristics of a "complex" genetic trait; therefore, it is necessary to look at very large numbers of patients, far more than exist at any single organization, to eliminate gaps in the current understanding of this complex chronic disorder. Advances may be achieved by bringing together food allergy data from large numbers of patients into a Data Commons, a secure and efficient platform for researchers, comprising standardized data, available in a common interface for download and/or analysis, in accordance with the FAIR (Findable, Accessible, Interoperable, and Reusable) principles. Prior data commons initiatives indicate that research community consensus and support, formal food allergy ontology, data standards, an accepted platform and data management tools, an agreed upon infrastructure, and trusted governance are the foundation of any successful data commons. In this article, we will present the justification for the creation of a food allergy data commons and describe the core principles that can make it successful and sustainable.

Development of a social and environmental determinants of health informatics maturity model.

Introduction: Integrating social and environmental determinants of health (SEDoH) into enterprise-wide clinical workflows and decision-making is one of the most important and challenging aspects of improving health equity. We engaged domain experts to develop a SEDoH informatics maturity model (SIMM) to help guide organizations to address technical, operational, and policy gaps. Methods: We established a core expert group consisting of developers, informaticists, and subject matter experts to identify different SIMM domains and define maturity levels. The candidate model (v0.9) was evaluated by 15 informaticists at a Center for Data to Health community meeting. After incorporating feedback, a second evaluation round for v1.0 collected feedback and self-assessments from 35 respondents from the National COVID Cohort Collaborative, the Center for Leading Innovation and Collaboration's Informatics Enterprise Committee, and a publicly available online self-assessment tool. Results: We developed a SIMM comprising seven maturity levels across five domains: data collection policies, data collection methods and technologies, technology platforms for analysis and visualization, analytics capacity, and operational and strategic impact. The evaluation demonstrated relatively high maturity in analytics and technological capacity, but more moderate maturity in operational and strategic impact among academic medical centers. Changes made to the tool in between rounds improved its ability to discriminate between intermediate maturity levels. Conclusion: The SIMM can help organizations identify current gaps and next steps in improving SEDoH informatics. Improving the collection and use of SEDoH data is one important component of addressing health inequities.

Development of Food Allergy Data Dictionary: Toward a Food Allergy Data Commons.

BACKGROUND: Food allergy (FA) data lacks a common base of terminology and hinders data exchange among institutions. OBJECTIVE: To examine the current FA concept coverage by clinical terminologies and to develop and evaluate a Food Allergy Data Dictionary (FADD). METHODS: Allergy/immunology templates and patient intake forms from 4 academic medical centers with expertise in FA were systematically reviewed, and in-depth discussions with a panel of FA experts were conducted to identify important FA clinical concepts and data elements. The candidate ontology was iteratively refined through a series of virtual meetings. The concepts were mapped to existing clinical terminologies manually with the ATHENA vocabulary browser. Finally, the revised dictionary document was vetted with experts across 22 academic FA centers and 3 industry partners. RESULTS: A consensus version 1.0 FADD was finalized in November 2020. The FADD v1.0 contained 936 discrete FA concepts that were grouped into 14 categories. The categories included both FA-specific concepts, such as foods triggering reactions, and general health care categories, such as medications. Although many FA concepts are included in existing clinical terminologies, some critical concepts are missing. CONCLUSIONS: The FADD provides a pragmatic tool that can enable improved structured coding of FA data for both research and clinical uses, as well as lay the foundation for the development of standardized FA structured data entry forms.

Characterizing Biphasic Food-Related Allergic Reactions Through a US Food Allergy Patient Registry.

BACKGROUND: Understanding about patient-reported biphasic food-related allergic reactions is currently sparse. OBJECTIVE: To characterize patient-reported biphasic food-related allergic reactions among a national food allergy registry. METHODS: We used two patient registry surveys established by Food Allergy Research and Education. Variables were described with proportions and 95% confidence intervals (CIs); unadjusted results were stratified by respondent type. Multivariable logistic regression evaluated the adjusted odds of reporting a biphasic reaction. RESULTS: The incidence of reported biphasic reactions was 16.4% (95% CI, 15.3-17.7). A total of 12.8% of parent or guardian respondents (95% CI, 12.5-14.3) and 21.8% of self-respondents (95% CI, 19.7-23.8) indicated a biphasic reaction during their most recent food-allergic reaction. Among respondents with a mild initial reaction, 7.4% reported a biphasic reaction, compared with 30% with a very severe initial reaction. When the initial reaction was mild, 69.6% of parent or guardian respondents (95% CI, 47.2-85.4) and 52.0% of self-respondents (95% CI, 38.0-35.7) with a biphasic reaction reported a mild secondary reaction. When the initial reaction was very severe, 36.3% of parent or guardian respondents (95% CI, 26.4-47.5) and 42.9% of self-respondents (95% CI, 31.1-55.5) with a biphasic reaction reported a very severe secondary reaction. Female sex, Black race, reaction age 5-12 and 26-66 years, initial moderate, severe, or very severe reaction, and one or more annual reactions were associated with increased odds of a biphasic reaction. CONCLUSIONS: This study characterizes the incidence of patient-reported biphasic reactions and provides valuable information on the probable severity of a biphasic food-related allergic reaction. Further research is necessary to understand the epidemiology of food-related biphasic reactions.

Oral Mucosal Lesions in a Cross-Sectional Study of 200 Dermatologic Outpatients.

Oral mucosal lesions (OMLs) present with a variety of manifestations, emanating largely from tobacco chewing, smoking, and consumption of alcohol. Evolution of the lesions may be facilitated by poor oral hygiene and restorative dental materials, as well as by trauma, infections, and immune-mediated diseases. Two hundred consecutive patients seen at a pre-eminent dermatologic clinic formed the study group. They were interviewed about clinical manifestations, duration of the lesion, patient's age and sex, and incriminating factors. After informed consent had been gained, a thorough clinical examination was performed to define the precise morphology, site, and distribution of lesions. Confirmation of the clinical diagnosis by histopathology and other relevant techniques was confirmed.

Oral Lichen Planus: A Cross-Sectional/Descriptive Study of 33 Patients.

Oral lichen planus (OLP), a well-known entity, is often neglected; however, its assessment is considered essential for evolving future strategies for treatment. Thirty-three patients with OLP from 200 consecutive patients with oral mucosal lesions were studied according to demography. Tobacco chewing, smoking, and alcohol intake were recorded. Examination of the oral cavity, using a head light and tongue depressor, was undertaken to define the morphology of the lesion(s). Colored photographs were an essential part of the process. OLP, a frequently encountered manifestation of oral mucosal lesions, was responsible for 16.50% of the total number of lesions. There was a preponderance of lesions in women aged 40 to 59 years, in contrast to men in the same age group. The duration of the lesions was variable, and tobacco chewing/smoking and amalgam fillings might have exacerbated them. Morphology ranged from a reticular, erythematous pattern to an erosive one. The diagnosis is largely clinical, but it can be confirmed by histopathology.

Oral Mucosal Lesions: Miscellaneous-Part III.

Oral mucosal lesions are a common occurrence in dermatology. In part III of this series, the authors discuss the epidemiology and etiopathology of these lesions, including clinical classifications, modifying factors, and incriminating agents.

Oral Mucosal Lesions: Oral Cavity Biology-Part I.

It is important to evaluate the background of oral cavity biology to define morphologic abrasions in oral mucosa following a host of local and/ or systemic disorders. The oral cavity is not only the beginning of the digestive system, but it also plays a significant role in communication; the voice (although the voice is produced in the throat), tongue, lips, and jaw are its essential components to produce the range of sounds. The vestibule and the oral cavity are its major parts, and are usually moist. The lips and the teeth are in approximation, marking its start up. The anatomy of the oral cavity in brief has been reviewed in right prospective for disease related changed morphology, thus facilitating interpretation.

Oral Mucosal Lesions: Oral Lichen Planus and Lichenoid Tissue Reaction/Interface Dermatitis-Part II.

In order to succinctly interpret the clinical undertones of oral lichen planus and lichenoid tissue reaction/interface dermatitis, the well-recognized oral mucosal lesions, it is mandatory to comprehend oral cavity biology in the right perspective, the clinical connotations of which have been highlighted in perspective to facilitate diagnosis. In addition, a focus is formed on systemic association. Additionally, the imperative of salient histopathology in the diagnosis is emphasized for instant reference.

Oral squamous cell carcinoma of the mandibular region presenting as multiple discharging sinuses: imperative of magnetic resonance imaging and computerized tomography.

A 40-year-old woman presented with red swelling of the right mandibular region of the face. She had several painful, progressive, ulcerative, raised serosanguinous discharging sinuses. The presence of granules and bony contents were not reported. She was an habitual tobacco and betel chewer for the past 20 years. There was no history of injury/trauma over the site in the past. Progressive loss of appetite and body weight was prominent. She was nonambulatory and denied treatment.

Exclusive plaque psoriasis of the lips: efficacy of combination therapy of topical tacrolimus, calcipotriol, and betamethasone dipropionate.

A 16-year-old unmarried woman presented with recurrent cracking of the lips indicated by the appearance of grayish white flakes since October 2004, which, in due course, shed off leaving behind an apparently normal mucous membrane. Chewing roasted corn treated with salt and lemon (bhutta) initially caused the lesions. Ever since, it has been a cause of its exacerbation. She never had any relief with either systemic or topical treatment. In fact, an obsession had overtaken her, resulting in a psychological setback. She denied regular drug use for any other ailment. Her menstrual cycle was normal. There was a positive history of psoriasis in her mother. Examination of the lips was conspicuous. It was marked by the presence of a well-circumscribed, moist, raised plaque (Figure 1). Its surface was irregular, with elevation and depression. It was made up of thick, grayish white scales, which were arranged in layers; however, Grattage/Auspitz sign could not be elicited. Fissuring was prominent but the buccal mucosa, surface of the tongue, gingiva, and palate were normal. The clinical examination did not reveal any evidence of skin and/or nail psoriasis/psoriatic arthropathy or any other systemic abnormality. Blood examination including total and differential leukocyte count, complete hemogram, and liver and renal function tests were normal. Biopsy of the representative lesion was subjected to serial sections. They were stained with hematoxylin-eosin to work up microscopic pathology. It revealed the presence of mounds of parakeratosis with numerous neutrophilic Munro microabscesses (Figure 2). Submucosal vessels were dilated and congested. Periodic-acid-Schiff (PAS) stain revealed fungal hyphae and spores within the parakeratotic layer. Colonies of Gram-positive cocci were also demonstrated on the surface of the mucosa. She was administered combination therapy, comprising topical tacrolimus (0.1%) ointment and calcipotirol hydrate (50 microg/g) plus betmethasone dipropionate (0.5 mg/g) twice a day for 7 days. A single bolus dose of fluconazole 450 mg orally was also administered. The response to treatment was favorable and the lesions showed regression (Figure 3).

Lichenoid tissue reaction/interface dermatitis: recognition, classification, etiology, and clinicopathological overtones.

Lichenoid tissue reaction or interface dermatitis embrace several clinical conditions, the prototype of which is lichen planus and its variants, drug induced lichenoid dermatitis, special forms of lichenoid dermatitis, lichenoid dermatitis in lupus erythematosus, and miscellaneous disorders showing lichenoid dermatitis, the salient clinical and histological features of which are described to facilitate their diagnosis. Background of lichenoid reaction pattern has been briefly outlined to enlighten those interested in this entity.

Public-private mix TB activities in Meerut, Uttar Pradesh, North India: delivering dots via collaboration with private providers and non-governmental organizations.

BACKGROUND: We evaluated the contribution of public-private collaboration between the Indian tuberculosis (TB) programme and the private health sector (including non-governmental organizations and private providers) to TB case-detection and treatment outcomes in Meerut district, India. METHODOLOGY: District TB registers from January 2001-June 2003 were reviewed. RESULTS: The 2002 new AFB-positive case-notification rate (103/100,000 population) in Meerut exceeded national targets. Of the 7,062 new AFB-positive patients registered, 2,084 (29%) were detected at private sector microscopy and DOTS treatment centres; treatment outcomes met programme targets. CONCLUSION: Public-private collaborations can be successfully implemented at the district level in India, and have the potential for substantial contributions to TB control efforts in India.
