Choking, gagging and complementary feeding methods in the first year of life: a randomized clinical trial

Abstract Objective: Compare the occurrence of choking and gagging in infants subjected to three complementary feeding (CF) methods. Methods: Randomized clinical trial with mother-infant pairs, allocated according to the following methods of CF: a) Parent-Led Weaning (PLW) — group control, b) Baby-Led Introduction to SolidS (BLISS), and c) mixed (initially BLISS and if the infant presents a lack of interest or dissatisfaction, PLW), with the last two methods guided by the infant. Mothers received nutritional intervention on CF and prevention of choking and gagging according to the method at 5.5 months of age and remained in follow-up until 12 months. Frequencies of choking and gagging were collected by questionnaire at nine and 12 months. The comparison between groups was performed using the analysis of variance test (p < 0.05). Results: 130 infants were followed, and 34 (26.2%) children presented choking between six and 12 months of age, 13 (30.2%) in PLW, 10 (22.2%) BLISS, and 11 (26.2%) mixed method, no significative difference between methods (p > 0.05). The choking was caused mainly by the semi-solid/solid consistency. Moreover, 100 (80%) infants aged from six to 12 months presented gagging and their characteristics were not statistically different among groups (p > 0.05). Conclusion: Infants following a baby-led feeding method that includes advice on minimizing choking risk do not seem more likely to choke than infants following traditional feeding practice that includes advice on minimizing choking risk.

The effect of intravenous prophylactic administration of dezocine before anesthesia induction on choking during induction period of patients undergoing general anesthesia / 中国医师进修杂志

Objective:To investigate the effect of intravenous prophylactic administration of dezocine before anesthesia induction on choking during induction period in patients undergoing general anesthesia.Methods:A total of 92 patients with tracheal intubation surgery under general anesthesia from November 2020 to May 2021 in the Zhejiang Taizhou Hospital were selected and randomly divided into the observation groupand the control group by random number table, with 46 cases in each group. The observation group was intravenously injected with 0.1 mg/kg dezocine while the control group was intravenously injected with 0.9% sodium chloride 5 ml before anesthesia induction. Anesthesia induction was performed at 10 min after injection in the two groups. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and catecholamine, interleukin-6 (IL-6) levels were recorded at before anesthesia induction (T 0), 1 min before endotracheal intubation (T 1), 1 min after intubation (T 2), and 5 min after endotracheal intubation (T 3). The incidence and degree of choking, the agitation score, visual analog scale (VAS) score, Ramsay sedation score and the incidence of adverse reactions in the two groups were compared. Results:The levels of HR, SBP and DBP at T 0, T 1, T 2 and T 3 in the two groups had no significant differences ( P>0.05). The levels of catecholamine and IL-6 in the control group were higher than those in the observation group: (120.49 ± 15.13) ng/L vs.(113.53 ± 17.14) ng/L, (16.80 ± 2.61) ng/L vs. (13.46 ± 1.55) ng/L, there were statistical differences ( P<0.05). The recovery time to spontaneous breathing in the observation group was shorter than that in the control group: (8.76 ± 2.14) min vs. (9.87 ± 2.09) min, there was statistical difference ( P<0.05). The incidence of choking in the observation group was lower than that in the control group: 2.17%(1/46) vs. 21.74%(10/46), there was statistical difference ( P<0.05). The scores of agitation score and VAS in the observation group were lower than that in the control group, and the scores of Ramsay sedation score was higher than that in the control group: (1.43 ± 0.26) scores vs. (2.11 ± 0.14) scores, (3.55 ± 1.03) scores vs. (4.86 ± 1.15) scores, (3.13 ± 0.76) scores vs. (1.54 ± 0.32) scores, there were statistical differences ( P<0.05). The incidence of adverse reactions in the observation group was lower than that in the control group: 6.52%(3/46) vs. 23.91% (11/46), there was statistical differences ( χ2 = 5.39, P<0.05). Conclusions:For patients with tracheal intubation under general anesthesia, preventive injection of dezocine before anesthesia induction can effectively inhibit the stress response of patients, with little impact on the patients′ circulatory system and respiratory system, and can also effectively reduce the incidence of choking in the induction period.

Prevenção de "brincadeiras perigosas" na internet: experiência da atuação do Instituto DimiCuida em ambientes digitais / Prevention of "dangerous games" on the Internet: the experience of the DimiCuida Institute line of action in digital environments

Resumo As "brincadeiras perigosas" ("desafios online") fazem parte da cultura digital, atraindo milhares de crianças e adolescentes e causando severos danos à saúde. Este artigo buscou analisar a experiência do Instituto DimiCuida (IDC), em Fortaleza (CE), ação pioneira de prevenção de desafios online danosos à saúde, que se disseminam em diferentes ambientes da Web 2.0. O estudo teve como objetivos específicos analisar a emergência do Instituto; identificar os principais parceiros envolvidos, os ambientes digitais e analógicos onde atuam; além de entender as estratégias de prevenção desenvolvidas. Trata-se de um estudo de caso baseado em análise documental. O acervo, extraído de diversas plataformas digitais, foi processado com o Atlas Ti e submetido à análise temática. O IDC emerge da ressignificação existencial e política de uma experiência de luto e tem como característica enfatizar alternativas às atividades online, tendo como foco central a escola e seus agentes. Por se tratar de um campo em construção e sem referência precedente de atuação, a prevenção realizada nos ambientes digitais pouco explora a linguagem e recursos da internet, aposta no controle parental e pouco leva em consideração as experiências de corpo e as performances identitárias envolvidas nos desafios.

Abstract "Dangerous games" ("online challenges") are part of the digital culture, attracting thousands of children and adolescents and causing severe damage to their health. This study aimed to analyze the experience of the DimiCuida Institute (DCI) in Fortaleza, state of Ceará, Brazil, a pioneering initiative to prevent online challenges, disseminated in different Web 2.0 environments, which can harm young people's health. The specific objectives of this study sought to analyze the emergence of the Institute; identify the main partners involved in its network, assess the digital and analog environments in which they operate; and understand the prevention strategies developed. This is a case study based on document analysis. Our data, extracted from several digital platforms, was processed with Atlas Ti and subjected to thematic analysis. The DCI emerges from the existential and political resignification of a bereavement experience and is characterized by emphasizing alternatives to online activities, especially focusing on schools and their agents. Since this is still a field under construction and without previous references for lines of action, the prevention carried out in digital environments scarcely explores the language and resources of the Internet, betting on parental control and scarcely considering the experiences of the body and identity performances involved in the challenges.

Clinical features and prognosis of newborns with congenital fissure of larynx presented with choking / 中国小儿急救医学

Objective:To summarize the clinical features and prognosis of neonates with congenital fissure of larynx due to choking, and improve the diagnosis and treatment of congenital fissure of larynx by neonatal medical professionals.Methods:This study was a single-center retrospective case series report.With "choking" as the key word, combined with the information from the first page of the medical record, we searched in the electronic medical record system, and summarized the clinical characteristics and prognosis of neonates diagnosed as congenital fissure of larynx.The study period was from January 2017 to February 2021.Results:A total of seven cases were diagnosed as congenital fissure of larynx, accounting for 2.2% of the total number of hospitalized children due to choking during the same period.Among them, six cases were male, gestational age was 38 (36, 39) weeks, birth weight was 2 820 (2 255, 3 420) g, admission age was 18(5, 20) days and hospitalization duration was 26 (6, 45) days.The common clinical symptoms were choking (7/7) and cyanosis (5/7). Six of the seven children with fissure of larynx were clearly classified as type Ⅰ(two cases), type Ⅲ(three cases), and type Ⅳ(one case). All the seven cases were accompanied by other site/tracheal malformations or congenital abnormalities, among which four (4/7) cases had VACTERL syndrome.A total of three children (two cases of type Ⅲ and one case of type Ⅳ) underwent laryngeal cleft repair operation, and all died shortly after surgery.Four cases didn′t receive laryngeal cleft repair operation (two cases of type Ⅰ, one case of type Ⅲ, one case of parting was unknown), one case with type Ⅰ fissure of larynx accepted the tracheoesophageal fistula repair operation only, who was followed up until the age of two years and six months, and he could have normal diet, one case of typeⅠfissure of larynx with gastric tube discharge, who was followed up to one year and eight months old, could be normal diet too, the two cases of children with no difference between the growth with their peers; one case with type Ⅲ fissure of larynx was lost to follow-up; One case, whose classification was unknown, was followed up until he was 40 days old, and still could be fed orally.The physical development of the child was significantly behind that of the same age.Conclusion:Congenital fissure of larynx is rare, with choking as its main symptom and other malformations.Diagnosis and classification require fiberlaryngoscope and bolting laryngoscope under general anesthesia combined with bronchoscopy, which is difficult to treat.Type Ⅰ has a good prognosis, while type Ⅲ and Ⅳ have poor prognosis.

Low cost simulator for cardiopulmonary unobstructed and reunion procedures in infants / Simulador de baixo custo para procedimentos de desengasgo e reanimação cardiopulmonar em lactentes

INTRODUCTION: The use of realistic simulation methodology is used in several learning scenarios, allowing students to participate directly in the problematization of situations that require immediate professional action. OBJECTIVE: To develop, validate and validate a low cost simulator for cardiopulmonary resuscitation and resuscitation procedures in infants. METHODS: An experimental study carried out with undergraduate students of the 1st year of the Nursing course at a higher education institution in the State of Paraíba, developed a simulator model with dimensions similar to an infant with low cost materials and made possible the use as a prototype for Basic Life Support training. The prototype was developed with the accessories for disengagement and cardiopulmonary resuscitation maneuvers. The data collection instrument was a questionnaire based on the American Hearth Association Basic Life Support guideline to enable and validate the Basic Life Support training instrument. RESULTS: The low-cost prototype for Basic Life Support training was used as a learning object adequately and enabled the teaching-learning process as an accessible resource at low cost. Based on the questionnaire applied, we observed that there was an increase in the median number of correct answers and a reduction in the median of errors, which indicated an improvement in the acquisition of information and improvement in learning, observed through the test of Signal of Related Samples and the test of the Signs of Wilcoxon, (MA) and errors (ME), before and after training where it was found that there was an increase in MA and a reduction in ME with 5% significance (p <0.001). The frequencies of response modifications after training with the simulator were also studied by means of the two-tailed McNemar test where Q1, Q2, Q3, Q4, Q8, Q9, Q13 and Q15 questions showed significant changes (p <0, 05). CONCLUSION: A prototype was developed that simulated the training activity in Basic Life Support, which made it possible to carry out the procedures appropriately in positioning and simulation of cardiac resuscitation, mouth / nose ventilation, and tapping in the scapular region. Which allowed the validation of disengagement and resuscitation training as a low cost alternative for health education.

Choking – A Public Health Problem- Are We Prepared?

Choking or acute airway obstruction is the emergency condition which is usually first dealt by general public and only then by health professionals. It has been documented in literature that educating the public about choking hazards and its management can positively affect the incidence of choking events and mortality. (1) In the developed countries, Basic Life Support (BLS) courses and First Aid courses are routinely done by public and are aggressively pursued by government and health care givers but in India there is no such uniform program. Indian Society of Anesthesiologists (ISA) has developed indigenous CPR guidelines and they are also organizing affordable nationwide CPR training modules, at present their program does not deal with the choking, but hopefully as their program will gain more acceptance, they will also incorporate choking modules.

Recomendaciones sobre la prevención de la aspiración de cuerpos extraños orgánicos / Recommendations for the prevention of organic foreign bodies aspiration

La aspiración de un cuerpo extraño sigue siendo un problema pediátrico frecuente y potencialmente grave. La mayoría de los cuerpos extraños en la vía aérea son orgánicos. La educación de los padres y cuidadores sobre los riesgos de asfixia y cómo evitarla es un elemento crucial para reducir la incidencia de estos eventos. El rol del pediatra es clave para promover la prevención. Se señalan las características principales de los alimentos peligrosos y se presentan recomendaciones sobre comidas apropiadas para la edad, formas adecuadas de preparación de los alimentos y hábitos de alimentación seguros con el fin de disminuir su aspiración.

Foreign body aspiration remains a common and potentially serious pediatric problem. Most aspirated foreign bodies are food. The education of parents and caregivers about choking hazards and how to avoid them is critical to reduce the incidence of these events. The pediatricians play a key role in promoting injury prevention. We indicate the main characteristics of hazardous food and we present recommendations on age-appropriate meals, adequate forms of food preparation and behavioral rules at mealtimes in order to reduce food choking.

A Post-Mortem Medicolegal Study of Violent Asphyxial Deaths - An Autopsy Based Study

Background: The study was conducted in the mortuary of Babu Jagjivan Ram Memorial Hospital, Jahangir Puri, North-West district, Delhi to determine the frequency and epidemiology of violent asphyxial deaths in that region, in relation to age and gender variation. Duration of study: Autopsies conducted during January 1, 2012 to December 31, 2013. Methods: Out of 2479(two thousand four hundred seventy nine) medico legal deaths autopsied at B.J.R.M. Hospital Delhi, during the study period, details were collected for those medico legal deaths identified to be due to violent asphyxial deaths. Results: 219 out of 2479 medico legal deaths were identified to be violent asphyxial deaths, making incidence rate 8.83%. There were 149(68.03%) males and 70(31.97%) females. Male predominance was seen in all asphyxial deaths except manual strangulation and smothering. Hanging and drowning were leading causes of violent asphyxial deaths. Conclusions: This study concludes that immuno-toxicity by cypermethrin insecticide is not similar in male and female subjects.

"Brincadeira do desmaio": uma nova moda mortal entre crianças e adolescentes. Características psicofisiológicas, comportamentais e epidemiologia dos 'jogos de asfixia' / The "choking game": a new craze among Brazilian children and young people. Psychophysiological, behavioral and epidemiological characteristics of 'asphyxial games'

Resumo As 'brincadeiras do desmaio' são comportamentos de risco que têm se difundido rapidamente entre crianças e jovens, provocando dependência, acidentes e mesmo mortes, inclusive no Brasil. Estas atividades são realizadas para vivenciarem sensações eufóricas e fugazes, atraindo grande número de adeptos por meio de milhares de vídeos postados no YouTube. A problemática dos 'jogos de asfixia' é observada nas mídias digitais brasileiras, mas carece de estudos científicos. Por meio de revisão sistemática da literatura e de bibliografia complementar, este trabalho objetiva discorrer sobre os 'jogos de asfixia', alertando aos aspectos psicofisiológicos e comportamentais, aos riscos potenciais destas práticas e, também, apresentar dados epidemiológicos internacionais. Compartilhar essas informações no meio acadêmico é de extrema importância dada a necessidade de maiores conhecimentos sobre o tema, de realizar capacitação de profissionais e de propor medidas preventivas que sensibilizem crianças e jovens ao perigo potencial dos desmaios voluntários. Sensibilizar igualmente os pais e professores a atentarem aos sinais decorrentes destas práticas. É também relevante a busca de apoio dos governantes para o controle da divulgação de vídeos incitativos.

Abstract The 'choking game' is a risk-taking behavior that has spread quickly among children and young people, causing dependence, accidents and even death, including in Brazil. These activities are performed in order to experience fleeting euphoric sensations, attracting numerous participants through the thousands of videos posted on YouTube. The problem of 'asphyxial games' can be observed in the Brazilian digital media, although there is a lack of scientific studies. Through a systematic review of the literature and complementary material, this paper aims to address the 'asphyxial games', warning about the psychophysiological and behavioral effects of these practices, while also presenting international epidemiological data. Sharing this information in academic circles is extremely important given the need to acquire more knowledge on the topic, train professionals and propose preventive measures that raise awareness among children and young people of the potential danger of voluntary fainting. It is equally important to raise awareness among parents and teachers so they can identify the warning signs that children may be engaging in these practices. And finally, it is also necessary to request government support to control exposure to videos that encourage the behavior.

Effect evaluation of choking risk assessment and intervention on the choking prevention of homeless inpatients with psychiatric / 中国实用护理杂志

Objective To explore the effect evaluation of choking risk assessment and intervention on the choking prevention of homeless inpatients with psychiatricc. Methods Totally 163 homeless inpatients with psychiatric disorder were selected from July 2012 to June 2016, 56 cases from July 2012 to December 2013 were assigned to the control group, another 107 cases from January 2014 to June 2016 was set as the intervention group. The control group received routine nursing safety management, on the basis of it, the intervention group received choking risk assessment through choking risk assessment scales. To take choking risk intervention on the patients of reached choking danger threshold. The incidence of choking and choking ending were compared between the two groups and the choking risk levels and scores in the intervention group before and after intervention were also compared. Results The incidence of choking in the intervention group and the control group was 0.93%(1/107)and 10.71%(6/56)respectively. Choking ending: 2 heal, 3 aspiration pneumonia, 1 death of 6 cases in the control group and 1 case was cured, no death and aspiration pneumonia occurred in the intervention group, the statistical differences were significant (χ2=9.399,18.554, P < 0.01 or 0.05). There were 28.0% (30/107) reached level Ⅰ, Ⅱ and Ⅲ choking threshold in the intervention group and rank mean of choking risk scores were 41.29. After interventions were 8.4% (9/107) and 25.50 respectively, the statistical differences were significant (χ2=10.231, P<0.05;Z=7.511, P<0.01). Conclusions The corresponding nursing intervention on the patients of choking risk can reduce and avoid choking accidents and protect the safety of homeless inpatients with psychiatric disorder effectively and improve the quality of care.

Aphonia after shoulder surgery: case report / Afonia após cirurgia do ombro: relato de caso

ABSTRACT In this case report we highlight the uniqueness of aphonia as, to the best of our knowledge, cases of aphonia related to interscalene brachial plexus block (IBPB) are not described in the literature. Although hoarseness is a common complication of IBPB, aphonia is not. Therefore, we think it is important to publicize the first case of aphonia after IBPB, which may have arisen only because of a recurrent laryngeal nerve chronic injury contralateral to the IBPB site.

RESUMO Relativamente a este relato de caso destacamos a sua singularidade, uma vez que não se encontram descritos na literatura, tanto ou quanto os autores puderam investigar, casos de afonia após uma anestesia combinada com bloqueio do plexo braquial via interescalénica (BPBI). Embora a rouquidão seja uma complicação frequente do BPBI, a afonia não o é. Desse modo, pensamos ser importante dar a conhecer o primeiro caso de afonia após o BPBI, que na opinião dos autores surgiu apenas por causa de uma lesão crônica do nervo laríngeo recorrente contralateral ao local do BPBI.

A retrospective analysis of the risk factors for choking in patients with dysphagia / 中华物理医学与康复杂志

Objective To explore effective precautions and interventions for choking in dysphagia patients.Methods Clinical data on f dysphagia patients hospitalized from September 1,1996 to Aug 8,2014 were retrospectively analyzed to correlate choking with gender,age,consciousness,type of aspiration,food-intake pathway and food texture.Results Only 0.17％ of the patients (n =8) were found to have choked,and 6 of them were men.Children,teenagers,the middle-aged and the aged constituted 25％,12.5％,37.5％ and 25％ of the patients respectively.75％ were conscious and 62.5％ displayed silent aspiration.6 cases used oral intake and 2 used nasogastric tube feeding.Among the 8 choking patients,half ate solid food,2 semisolid and 2 liquid food.Six survived and 2 died.Conclusion The risk factors for choking include silent aspiration and oral intake of solid or semisolid food.The successful rescue rate for choking is relatively low,so clinicians should be aware of and try to eliminate these risk factors.

CHOKING IN A PSYCHIATRIC PATIENT - A CASE REPOR

Choking is one of the important types of asphyxia deaths. The incidences of which are not uncommon. The choking in children could be due toys, coins, marbles, nuts and any other small hard object or even sometimes due to stuffed in plastic bags whereas in adults most of the times food bolus or hard parts of food like bone pieces are responsible. It is mostly accidental in nature. It can cause coughing or sometimes airway obstruction leading to death. We present a case wherein a mentally ill person accidentally choked to death after consumption of food.

Oral Bio Dissolving Films in Dentistry: A New Perspective in Treatment Modality.

The environment of oral cavity provides a large surface area for the delivery of drugs bypassing the first pass metabolism in the liver. Hence, the oral cavity is being targeted for providing quicker delivery of drugs for immediate action. However, oral delivery system in the form of tablets/ capsules needs modifications in elderly, children, and unconscious patients because of the fear of choking and aspiration. To overcome these problems much research is being undertaken to develop oral bio dissolving films as an alternative to tablets. The objective of the article was to provide an overview of the composition, advantages and disadvantages, and uses of bio dissolving films in the field of medicine and dentistry.

Fobia de deglutição: discussão analítico-comportamental de seus determinantes e da amplitude da mudança / Choking phobia: a behavior-analytic discussion concerning its determinants and the amplitude of change

A terapia analítico-comportamental de uma mulher de 35 anos, cujo caso foi anteriormente publicado estritamente em termos de seus aspectos psiquiátricos, é agora abordada com relação aos determinantes encontrados na história de vida da fobia de deglutição e de outras respostas da mesma classe funcional, todas envolvendo a esquiva experiencial. A psicoeducação envolveu uma detalhada análise funcional da fobia de deglutição e dos problemas de relacionamento, correlacionando numa única perspectiva ambos os fenômenos. A teoria dos quadros relacionais oferece uma possível explicação para o fato de que a cliente promoveu uma extensa e progressiva mudança no padrão alimentar e no relacionamento com pessoas significativas, após unicamente uma série de sessões de exposição gradual, com a presença do terapeuta, a diferentes grupos de alimentos, num delineamento de linha de base múltipla.

The behavior-analytic therapy of choking phobia in a 35 yrs-old woman, a case previously published focusing strictly on its psychiatric aspects, is now presented concerning specific life history determinants of both choking phobia and other responses of the same functional class, all of them involving experiential avoidance. Psychoeducation included detailed functional analysis of choking phobia and relationship problems, correlating both set of phenomena under a single perspective. By means of therapist-assisted graded exposure sessions to different sets of foods, according to a multiple baseline design, the fear subsided and ingesta returned to normal levels. In parallel, significant changes occurred in relationship patterns. Relational frame theory provides a possible explanation to the fact that the client promoted extensive and progressive changes in her eating pattern and relationship with significant others.

Gastric contents in respiratory tract a diagnostic dilemma at autopsy.

Gastric contents in the respiratory tract are commonly found at postmortem in acute alcoholism, occasionally during a fit of epilepsy and in dead bodies that have started decomposing. Quite infrequently it may be found in fresh bodies that have undergone sudden unexpected and unattended death leading to a dilemma as to the real cause of death with dearth of any other substantial evidence. Dead body of a 36-year-old lady was brought for post-mortem examination with history of unattended and unexpected death while taking bath after her afternoon meal. On gross and histopathological examination, there was no significant finding in the cardiovascular system but respiratory tract contained gastric contents with histopathology confirming vegetable matter in the terminal bronchioles. The conflicting literature on the difference between antemortem aspiration and postmortem spill of gastric contents into the respiratory tract led to a dilemma as to the real cause of death in present case. Dilemmas of the case with difficulties in diagnosis are being presented herewith.

Choking phobia: full remission following behavior therapy / Fobia de deglutição: remissão com terapia comportamental

OBJECTIVE: A phobic behavior pattern is learned by classical and operant conditioning mechanisms. The present article reviews the main determinants of choking phobia etiology and describes the behavior therapy of an adult patient. METHOD: Psychoeducation, functional analysis, and graded exposure to aversive stimuli were used to treat the patient, after extensive psychiatric and psychological assessment. Ingesta and anxiety levels were measured along treatment and at follow-up. RESULTS: A multiple assessment baseline design was used to demonstrate the complete remission of symptoms after seven sessions, each of them exposing the patient to a different group of foods. CONCLUSION: Psychoeducation and exposure were critical components of a successful choking phobia treatment.

OBJETIVO: O padrão comportamental da fobia é adquirido com base no condicionamento clássico e mecanismos operantes de aprendizagem. Este artigo faz uma revisão dos principais determinantes da etiologia da fobia de deglutição e descreve o tratamento da terapia comportamental em uma paciente adulta. MÉTODO: Foram usadas psicoeducação, análise funcional e gradativa exposição a estímulos aversivos no tratamento da paciente, depois de uma extensiva avaliação psiquiátrica e psicológica. Níveis de ingesta e ansiedade foram medidos ao longo de todo o tratamento e no follow-up. RESULTADOS: Para demonstrar a completa remissão dos sintomas, após sete sessões de exposição a diferentes grupos de alimentos foi usado um delineamento de linha de base de avaliações múltiplas. CONCLUSÃO: Terapia de exposição e psicoeducação foram componentes que contribuíram de modo crítico para a obtenção de resultados positivos ao tratamento.

Analisa o relatório de Arthur Neiva e Belisario Penna , focalizando a contribuição dos autores ao estudo de uma das doenças endêmicas por eles encontrada ao longo de todo o trajeto percorrido, de longa data conhecida popularmente por 'mal de engasgo'. Observaram e descreveram com minúcia os sintomas apresentados pelos doentes e a associação frequente do mal de engasgo com outro mal endêmico conhecido por 'vexame' ou 'vexame do coração', que consistia em crises de palpitações. Os estudos epidemiológicos e clínicos de Neiva e Penna sobre o mal de engasgo muito contribuíram para o conhecimento dessa afecção e representaram um incentivo para todos os pesquisadores que se dedicaram ao seu estudo, especialmente quanto a sua relação com a doença de Chagas.

Analyze the report by Neiva and Penna, focusing on the contribution these authors made to the study of one of the endemic diseases encountered throughout their journey, which had been long known under the popular name of mal de engasgo (choking disease). They recorded their observations and detailed descriptions of the patients' symptoms and the association frequently encountered between mal de engasgo and another endemic disease, known as vexame or vexame do coração, characterized by bouts of palpitations. Neiva and Penna's epidemiological and clinical observations of mal de engasgo were crucial for all the researchers interested in the disease, especially its relationship with Chagas disease.

Engasgamento em bebês após busca às cegas com os dedos / Infants choking following blind finger sweep

OBJETIVO: Em situações estressantes, as pessoas geralmente usam os dedos para retirar corpos estranhos de faringe da boca. Este artigo relata três casos de óbito de bebês após o uso dessa técnica. MÉTODOS: Um total de 26 casos de engasgamento causado por aspiração de corpos estranhos nas vias respiratórias superiores e inferiores envolvendo crianças menores de 11 anos submetidas a autopsia no Departamento de Medicina Forense da Universidade da Jordânia entre 1996 e 2006 foram revisados. RESULTADOS: O uso de busca às cegas com os dedos para retirar corpos estranhos de faringe foi relatado em três bebês durante o choro. Todas as crianças eram menores de 1 ano e haviam se engasgado com grãos-de-bico, uma bola de gude e um lápis curto. A diversidade, o tamanho, a forma, e a maciez da superfície são as principais características que fazem com que esses corpos estranhos sejam mais difíceis de ser removidos com os dedos e facilitam sua entrada via respiratória. CONCLUSÃO: Esses casos mostraram que a busca às cegas com os dedos na boca de bebês durante o choro não é somente uma manobra perigosa, mas também pode ser fatal.

OBJECTIVE: In stressful situations, people usually use finger sweep to remove pharyngeal foreign bodies from the mouth. This article reports on three cases of death of infants following the use of this technique. METHODS: A total of 26 cases of choking caused by foreign bodies aspiration in the upper and lower respiratory passages involving children younger than 11 years of age autopsied at the Forensic Department of University of Jordânia between 1996 and 2006 were reviewed. RESULTS: Blind finger sweep to remove pharyngeal foreign bodies were reported in three crying infants. All of these cases were younger than 1 year of age and choked on a chickpea, a marble and a short pencil. Diversity, size, shape and smoothness of the surface are the main characteristics that render the foreign bodies less easily caught by fingers and make them easily enter the respiratory passage. CONCLUSION: These cases showed that blind finger sweep in crying infants is not only dangerous but can be a fatal maneuver.
