Hand, foot, and mouth disease outbreak by Coxsackievirus A6 during COVID-19 pandemic in 2021, São Paulo, Brazil.

INTRODUCTION: Hand, foot, and mouth disease (HFMD) is an acute febrile illness characterized by fever; sore throat; and vesicular eruptions on the hands, feet, and oral mucosa. Outbreaks of HFMD in children aged <5 years have been reported worldwide and the major causative agents are Coxsackievirus (CV)A16, enterovirus (EV)-A71 and recently CVA6. AIM AND METHODS: The aim of this study was to investigated a large outbreak of Hand, foot, and mouth disease during COVID-19 pandemic in 2021 from clinical samples of 315 suspected cases, in São Paulo State, Brazil. Diagnostic evaluation was performed by RT-qPCR, culture cell isolation and serological neutralization assay. EV-positive were genotyped by partial VP1 genome sequencing. RESULTS: One hundred and forty-nine cases analyzed were positive for enterovirus (47.3%; n = 149/315) by neutralizing test (n = 10 patients) and RT-qPCR (n = 139 patients), and identified as CVA6 sub-lineage D3 by analysis of VP1 partial sequences. CONCLUSIONS: This finding indicated the reemergence of CVA6 in HFMD, soon after the gradual easing of non-pharmaceutical interventions during-pandemic COVID-19 and the relevance of continued surveillance of circulating enterovirus types in the post-COVID pandemic era.

Topical formulations containing Copaifera duckei Dwyer oleoresin improve cutaneous wound healing.

OBJECTIVE: Evaluation of the healing and toxicological effects of Copaifera duckei Dwyer oleoresin (CDO). MATERIALS AND METHODS: Rodents with skin lesions were divided into nine groups, including daily treatments with 1, 3 and 10% CDO, collagenase, antibiotic ointment and control groups, for 14 days. RESULTS: Treatment with 10% CDO reduced skin edema and hyperplasia, demonstrating anti-inflammatory effect of the oil. Reduction in the wound area was observed, indicating the healing effect of CDO. Histopathological analysis showed increases in angiogenesis and re-epithelialization in animals treated with the highest concentration. On the other hand, no alterations in ulcerations, inflammatory infiltrate, hemorrhage, congestion, degeneration, percentage of collagen fibers, number of cells stained with anti-macrophage migration inhibitory factor, or density of area stained with anti-collagen I and III were found. Toxicogenetic analysis revealed no differences in micronucleus frequencies or in the ratio of polychromatic erythrocytes to total erythrocytes between treated and negative control, demonstrating the absence of genotoxicity and cytotoxicity, respectively. There was no difference in levels of liver enzymes among groups, indicating the absence of hepatotoxicity. CONCLUSION: Formulations of CDO exerted beneficial effects on the stages of cutaneous wound healing and are promising options for the treatment of wounds.

A study on the morphoquantitative and cytological characteristics of the bulbar conjunctiva of the maned wolf (Chrysocyon brachyurus; Illiger, 1815).

The maned wolf, Chrysocyon brachyurus, is a near-threatened carnivore inhabiting the Brazilian Cerrado. Few studies have been conducted on this species, and even fewer have explored its ophthalmological characteristics. Vision is critical to wild canids; thus, this study aimed to provide a morphoquantitative description of the bulbar conjunctiva of the maned wolf using cytological and histological analyses. Ten healthy maned wolves from a conservational centre, including 4 females and 6 males aged 1-12 years (6.5 ± 2.8), were included in the study. The samples for cytological analysis were collected from the inferior conjunctival sac using a cytobrush, and conjunctival tissue was collected for histological analysis from the temporal canthus zone. The cytological samples were stained using the Papanicolaou method, and the histological sections were stained using haematoxylin and eosin, Periodic acid-Schiff, picrosirius red and Masson's trichrome stains. The cytological samples were studied for stain quality, and the different cell types were counted. Histological examination was used to determine tissue types in the conjunctiva and their proportions. Analyses revealed a stratified squamous epithelium with some goblet cells and eventual pigmentation in the basal layer. Loose connective tissue with the presence of some mononuclear and polymorphonuclear cells was also observed. The epithelium of the maned wolf's bulbar conjunctiva resembles that of dogs and other carnivore species; furthermore, its physiological and pathological responses were similar to those of other carnivore species.

A comparative study of the cardiopulmonary and sedative effects of a single intramuscular dose of ketamine anesthetic combinations in rabbits.

The aim of this prospective, randomized, blinded crossover study was compare the cardiopulmonary and sedative effects of ketamine in combination with acepromazine, diazepam, dexmedetomidine, midazolam or xylazine, injected intramuscularly in rabbits, using eight one-year-old male New Zealand rabbits (4.1 ± 0.40 kg). All treatments included ketamine (K; 30 mg/kg) in combination with one of the following: acepromazine 0.5 mg/kg (treatment KA); diazepam 1 mg/kg (KD); dexmedetomidine 0.025 mg/kg (KDex); midazolam 1 mg/kg (KM); or xylazine 3 mg/kg (KX) mixed in the same syringe and injected intramuscularly. Cardiopulmonary variables, blood gases and sedative scores were measured before injection (T0 or baseline) and every 10 min thereafter, over a 60-min period. There were reductions in heart rate, compared with the baseline, at all evaluation times in treatment KX. Treatments KDex, KM and KX presented reductions in respiratory rate at all evaluation times, in comparison with the baseline. There were reductions in mean arterial pressure in KA and KX at times T10-T60 and in PaO2 in KDex, KM and KX at T10-T50. The sedation scores were similar in KA, KDex, KM and KX at T10-T20. Ketamine in combination with acepromazine, dexmedetomidine, midazolam or xylazine promoted similar sedative effects for twenty minutes, but the α2-agonists can promote hypoxemia.

Effects of pneumoperitoneum and trendelenburg position on intraocular pressure (IOP) in isofluorane anesthetised cats / Efeitos do pneumoperitônio e da posição de trendelenburg sobre a pressão intraocular em gatos anestesiados com isoflurano

The aim of this study was to determine whether a pneumoperitoneum of 10 mmHg combined or not with the Trendelenburg position could lead to significant changes in intraocular pressure (IOP), ocular pressure perfusion (OPP), and cardiorespiratory variables; as well as determine whether a correlation exists between IOP and mean arterial blood pressure (MAP), and/or partial pressure of carbon dioxide in arterial blood (PaCO2) in cats. Animals were allocated in two groups (n=7/group): GC (without inclination) and GTREN (Trendelenburg position). The variables were recorded before (baseline) and during 30 minutes (T5-T30) after insufflation. In GTREN, a reduction in heart rate was observed at T5 and in respiratory rate at T5 and T15. There was an increase in IOP at T5-T30 in comparison to baseline. There was a reduction in potential of hydrogen in arterial blood in both groups at all times in comparison to baseline. Partial pressure of carbon dioxide in arterial blood was increased at T15-T30 in GC and at T5-T30 in GTREN. In conclusion, the pneumoperitoneum of 10mmHg CO2 did not significantly affect IOP or OPP in cats anaesthetised with isofluorane and kept under spontaneous ventilation. However, induced pneumoperitoneum combined with Trendelenburg position resulted in an increase in IOP in cats subjected to the same anaesthetic conditions, but did not affect OPP.

O objetivo deste estudo foi determinar se o pneumoperitônio de 10 mmHg associado, ou não, à posição de Trendelenburg poderia levar a alterações significativas na Pressão Intraocular (PIO), Pressão de Perfusão Ocular (PPO) e variáveis cardiorrespiratórias, bem como determinar se havia correlação entre a PIO e a Pressão Arterial Média (PAM) e/ou Pressão Parcial de Dióxido de Carbono no Sangue Arterial (PaCO2) em gatos. Os animais foram alocados em dois grupos (n = 7/grupo): GC (sem inclinação) e GTREN (posição de Trendelenburg). As variáveis foram registradas antes (linha de base) e durante 30 minutos (T5-T30) após a insuflação. No GTREN, foi observada redução na frequência cardíaca em T5 e, na frequência respiratória, em T5 e T15. Houve aumento da PIO no T5-T30 comparativamente ao valor basal. Houve redução no Potencial de Hidrogênio no sangue arterial em ambos os grupos em todos os momentos comparativamente à linha de base. A Pressão Parcial de Dióxido de Carbono no sangue arterial aumentou em T15-T30 no GC e em T5-T30 no GTREN. Concluiu-se que o pneumoperitônio de 10mmHg CO2 não afetou significativamente a PIO ou a PPO em gatos anestesiados com isofluorano e mantidos sob ventilação espontânea. No entanto, o pneumoperitônio induzido combinado à posição de Trendelenburg resultou em aumento da PIO em gatos submetidos às mesmas condições anestésicas, mas não afetou a PPO.

Modified walking suture technique in rhytidectomy in a Shar-Pei dog / Técnica walking suture modificada na ritidectomia em shar-pei

Excessive facial skin folds is observed in several breeds of dogs and the weight exerted on the eyelids accents or promotes entropion, trichiasis and ptosis. Thus, this study reported a case of the 8-months-old male Shar-pei weighting 21.5kg was presented with an obstructed visual axis, eye discharge, fetid odor in facial folds around the jaw and the neck. It was indicated the surgical resection of the folds and correction of the upper and lower entropion. In this case, the association of Hotz-Celsus technique with rhytidectomy shaped in semiarchs, using the anchoring points with the modified walking suture, was effective in correcting the entropion and unblocking the visual axis with minimal scarring and preservation of the breed standard in 12 months follow up after surgery.

O excesso de pregas faciais é observado em várias raças de cães e o peso exercido sobre as pálpebras acentua ou promove entrópio, triquíase e ptose. Assim, este estudo relata o caso de Shar-pei, macho de 8 meses de idade, pesando 21,5 kg que apresentava o eixo visual obstruído, secreção ocular e odor fétido nas dobras faciais em torno da mandíbula e do pescoço. Foi indicada a ressecção cirúrgica das pregas e a correção do entrópio superior e inferior. Neste caso, a associação da técnica de Hotz-Celsus com a ritidectomia em forma de semiarcos, utilizando pontos de ancoragem com a técnica "walking suture" modificada, foi efetiva na correção do entrópio e na liberação do eixo visual, com mínima cicatriz e preservação do padrão da raça 12 meses após a cirurgia.

Effect of systemic administration of phytosterol on lacrimal quality of dogs / Efeito da administração sistêmica de fitoesterol na qualidade lacrimal de cães

The tear lipid layer (oily outer layer) reduces evaporation and prevents tear overflow. In dogs, reductions in the lipid components of this layer (cholesterol, triglycerides and phospholipids) can cause eye serious diseases. In this way, the tear crystallization test analyzes the lacrimal quality, however, it is less used in veterinary. As phytosterol reduces blood cholesterol, the objective of this study was to investigate, through the tear crystallization test, whether the systemic administration of this drug influences the lacrimal quality of healthy dogs and, in addition, to verify differences in the interpretation of the ophthalmic test between different evaluators. Eight beagles, healthy, of both sexes, young and adults, without clinical ophthalmic signs apparent were selected. Basal lacrimal samples (D0) were collected from the right and left eye of all animals with glass capillary tube and arranged on a glass slide for scanning the images and subsequent microscopic analysis. Subsequently, all were medicated with the phytosterol (Collestra® 650 mg: 1 capsule, orally, every 12 hours, for 15 days). After seven (D7) and fifteen (D15) days of this systemic administration, the tear crystallization test in both eyes of all dogs was again performed for statistical comparison with the baseline results. The photographs of the slides were classified by four evaluators (AV1 and AV2 with professional experience in ophthalmology and AV3 and AV4 without previous professional experience in ophthalmology), following standards established by Rolando (1984). The results were statistically verified by analysis of simple variance (ANOVA One-Way). There was no statistical difference in the tear crystallization test between the established periods and in relation to the different ophthalmic test evaluators (p≤0.05). Although phytosterols reduce blood cholesterol levels, it was observed in the present study that these drugs when administered systemically did not interfere in the tear lipid layer and, consequently, in the lacrimal quality of healthy dogs, and may be prescribed as lipid-lowering agents for patients with ocular diseases, especially the lacrimal ones.

A camada lipídica lacrimal (camada externa oleosa) reduz a evaporação e previne o transbordamento lacrimal. Em cães, reduções nos componentes lipídicos desta camada (colesterol, triglicérides e fosfolipídios) podem causar doenças graves nos olhos. Desta forma, o teste de cristalização lacrimal analisa a qualidade lacrimal, no entanto, é menos utilizado em veterinária. Como o fitoesterol reduz o colesterol sanguíneo, o objetivo deste estudo foi investigar, através do teste de cristalização lacrimal, se a administração sistêmica deste fármaco influencia na qualidade lacrimal de cães hígidos e, além disso, verificar diferenças na interpretação do teste oftalmológico entre diferentes avaliadores. Oito beagles, saudáveis, de ambos os sexos, jovens e adultos, sem sinais oftalmológicos clínicos aparentes foram selecionados. Amostras lacrimais basais (D0) foram coletadas do olho direito e esquerdo de todos os animais, com tubo capilar de vidro e, dispostas em lâmina de vidro para escaneamento das imagens e posterior análise microscópica. Ato contínuo todos foram medicados com o fitoesterol (Collestra® 650 mg: 1 cápsula, por via oral, a cada 12 horas, durante 15 dias). Após sete (D7) e quinze (D15) dias desta administração sistêmica, o teste de cristalização lacrimal em ambos os olhos de todos os cães foi novamente realizado para comparação estatística com os resultados basais. As fotografias das lâminas foram classificadas por quatro avaliadores (AV1 e AV2 com experiência profissional em oftalmologia e AV3 e AV4 sem experiência profissional prévia em oftalmologia), seguindo padrões estabelecidos por Rolando (1984). Os resultados foram estatisticamente verificados pela análise de variância simples (ANOVA One-Way). Não houve diferença estatística no teste de cristalização lacrimal entre os períodos estabelecidos e em relação aos diferentes avaliadores de teste oftalmológico (p≤0,05). Embora os fitoesteróis reduzam os níveis de colesterol no sangue, observou-se no presente estudo que esses fármacos quando administrados sistemicamente não interferiram na camada lipídica da lágrima e, consequentemente, na qualidade lacrimal de cães hígidos, podendo ser prescritos como agentes hipolipemiantes para pacientes com doenças oculares, especialmente as lacrimais.

Methods: A Cross-sectional study. 73 videofluoroscopic swallow studies (VFSS)were conducted on patients after stroke The study subjects were divided into : group 1 (G1) consisting of 39 individuals with left cortical lesion and group 2 (G2) consisting of 34 individuals with right cortical lesions. The VFSS of G1 and G2 subjects were analyzed using puree (A) and liquid (B) consistencies, and  were also subdivided into young adults and older persons. . The mean PRT was divided into times shorter and longer than 250 ms. Results: No statistically significant difference was observed between G1 and G2 for the A and B consistencies, being obtained : G1 (A mean: 56.6 ms; B mean: 99.5 ms; A mean: 3627 ms; B mean: 1712 ms) and G2 (A mean: 79.6 ms; B mean: 110.7 ms; A mean: 2040 ms, B mean: 1529 ms), for PRT shorter (A:p = .673; B: p = 1.000) and longer (A: p = .435; B: p = .847) than 250 ms, respectively. No statistically significant difference was found regarding the variable age in the comparison between young and old adults for mean PRT according to the A and B consistencies in G1 (A: p = .260; B: p = .732) and G2 (A: p = .586; B: p = .104). Conclusion: No relationship between PRT and lateralization of brain lesion was observed with respect to subject age and to the swallowing of different food consistencies.

Doença de mão, pé e boca por enterovirus: revisão da literatura / Enterovirus hand, foot and mouth disease: literature review

A Doença de Mão, Pé e Boca (DMPB) é uma afecção exantemática ocasionada pelos enterovirus, principalmente pelo coxsackievirus A-6 e enterovirus A-71. Acomete principalmente indivíduos de 0 a 5 anos com manifestações clínicas como febre e odinofagia e, em casos mais graves, infecção no Sistema Nervoso Central e óbito. Os agentes etiológicos da DMPB são relatados no mundo todo, especialmente em países asiáticos e regiões do Pacífico. Por se tratar de um problema de saúde pública, diversos países realizam a vigilância epidemiológica, inclusive a Organização Mundial da Saúde. No Brasil, a notificação não é compulsória sendo realizada somente em casos de surto. Portanto, o presente trabalho teve como objetivo realizar uma revisão de literatura sobre a Doença de Mão, Pé e Boca no Brasil e no mundo, considerando os aspectos epidemiológicos, prevenção e as características dos agentes etiológicos. Para tal, 61 referências foram selecionadas em buscadores. Diversos trabalhos demonstraram que os agentes etiológicos da DMPB foram se alterando ao longo do tempo com circulação de sorotipos diferentes em diferentes localidades. Também se destaca a possível influência das alterações climáticas na ocorrência de surtos em países da Ásia. Portanto ações governamentais e de vigilância faz-se necessária também no Brasil a fim de maiores informações a DMPB, seus agravos e surtos.

Use of Copaifera multijuga for acute corneal repair after chemical injury: A clinical, histopathological and toxicogenetic study.

Copaiba oil is widely used in medicine, but there are no reports regarding its application in ophthalmology. Therefore, the objective of this study was to evaluate the clinical, histopathological and toxicogenetic effects of eye drops containing 0.1 and 0.5% of Copaifera multijuga Hayne oil on superficial corneal ulcers induced with alkali in the left eye of rats. For histological analysis, the percent reduction in ulcers and thickness of the corneal epithelium and stroma were evaluated 48 and 72 h after ulcer induction. Additionally, neovascularization and polymorphonuclear infiltration were classified in the stroma. The bone marrow micronucleus test was used for toxicogenetic assessment. None of the animals exhibited clinical signs of immediate ocular discomfort after instillation and the eye drops were harmless to the ocular surface. There was a significant difference in percent ulcer reduction and corneal stroma thickness between animals treated with the C. multijuga eye drops and untreated animals with corneal injury and the negative control, respectively, suggesting a healing effect of the oleoresin. Analysis of the thickness of the corneal epithelium at the two time points showed that the eye drops formulated did not significantly reduce the damage caused by alkali. The same was observed for the treatments with the reference drugs. No difference in stromal neovascularization or inflammatory infiltration was observed between the treated groups. The toxicogenetic results revealed the absence of cytotoxicity and genotoxicity of the treatments. In conclusion, the C. multijuga eye drops did not cause damage to the ocular surface under the present experimental conditions and corneal epithelization was similar to the conventional treatments. These results indicate that eye drops containing C. multijuga oleoresin are a promising option for the treatment of superficial keratitis.

RESUMO Introdução O tempo de trânsito orofaríngeo se modifica de acordo com inúmeras variáveis. Objetivo Comparar o tempo de trânsito oral total (TTOT) e a lateralidade da lesão cerebral no indivíduo após acidente vascular encefálico (AVE), com disfagia orofaríngea. Métodos Foram analisados 61 exames de videofluoroscopia da deglutição de indivíduos pós-AVE hemisférico unilateral e isquêmico. Os participantes foram divididos em dois grupos: O Grupo 1 (G1) foi composto de 30 indivíduos com lesão cortical direita e o Grupo 2 (G2), de 31 indivíduos com lesão cortical esquerda. A análise quantitativa do TTOT foi feita por dois juízes treinados no procedimento, por meio de software específico e foi realizada a análise da confiabilidade entre julgadores. Para a análise dos resultados, utilizou-se o teste Mann-Whitney. Resultados Verificou-se que, no G1, o TTOT foi maior que 2000 ms em 50% dos indivíduos e, no G2, em 94% dos indivíduos, ocorrendo diferença estatística significativa entre os grupos (p<0,01). Na comparação entre G1 e G2, para o TTOT, observou-se diferença estatística significativa (p=0,001). Entretanto, não houve diferença estatística significativa na comparação do G1 e G2, tanto para o TTOT menor que 2000 ms (p=1,000), como para o TTOT maior que 2000 ms (p=0,603). Contudo, verificou-se que, no G2, a média do TTOT maior que 2000 ms foi superior, quando comparada ao G1. Conclusão Houve tempo de trânsito oral total maior e menor que 2000 ms, em ambos os hemisférios corticais lesionados. A frequência de indivíduos com tempo de trânsito oral total maior que 2000 ms, bem como a média desse tempo, foram maiores na lesão cortical à esquerda no AVE.

ABSTRACT Introduction The oropharyngeal transit time changes according to several variables. Purpose To compare the total oral transit time (TOTT) and laterality of brain lesion in the individual after stroke with oropharyngeal dysphagia. Methods Analyzed 61 videofluoroscopic swallowing studies of individuals after unilateral cortical ischemic stroke. Participants were divided into two groups. Group 1 (G1) consisted of 30 individuals with right-side cortical lesion and group 2 (G2) of 31 individuals with left-side cortical lesion. Quantitative analysis of the TOTT was performed by two judges trained in the procedure by means of specific software and an analysis of the reliability between judges was performed. The Mann-Whitney test was used for the data analysis. Results It was found TTOT longer than 2000 ms in 50% of the G1 and in 94% of the individuals of G2 with a significant statistical difference between the groups (p<0.01). In the comparison between G1 and G2 regarding TOTT, it was verified that there was significant statistical difference (p=0.001). However, there was no significant statistical difference in the comparison between G1 and G2 for both TOTT shorter than 2000 ms (p=1.000) and TOTT longer than 2000 ms (p=0.603). However, it was found that in G2 the TOTT average is longer than 2000 ms and was greater than in G1. Conclusion There were TOTT shorter and longer than 2000 ms in both hemispheric cortical lesion. The frequency of individuals with TTOT are longer than 2000 ms and the average are greater in the left-side cortical lesion in stroke.

Intraocular pressure and Schirmer tear test values in maned wolf (Chrysocyon brachyurus) / Pressão intraocular e teste lacrimal de Schirmer em lobos-guará (Chrysocyon brachyurus)

The purpose of this study was to establish baseline data on lacrimal quantity (STT-1) and intraocular pressure (IOP) in captive maned wolves. Ten healthy adult maned wolves were contained with a snare pole and muzzle and kept in decubitus of the left side. STT-1 measurement was performed on the lateral third of the lower conjunctival sac for one minute. The cornea was desensitized and intraocular pressure was measured with an tonopen. Average STT-1 in both eyes was 11±5mm.min-1, with no statistical difference between the left and right eye (p=0.960). Average IOP in both eyes was 20±6mmHg, with no statistical difference between the left and right eye (p=0.836). Average STT-1 was lower than, and IOP was the same as normal levels found in dogs. There was no statistical difference in the age of the animals, and STT-1 and IOP values. In the present paper, average maned wolf STT-1 levels were lower compared with those found in dogs, while the IOP was the same in maned wolves as in dogs. Due to the increased incidence in providing emergency care for maned wolf victims of road kill and fires, determination reference values of ocular parameters may improve the correct diagnosis and treatment of the disease.(AU)

O objetivo deste estudo foi estabelecer dados de referência sobre a produção lacrimal (STT-1) e pressão intraocular (PIO) em lobos-guará em cativeiro. Foram utilizados 10 lobos-guará, saudáveis e adultos. Os animais foram contidos com cambão e mordaça e mantidos em decúbito lateral esquerdo. O TLS foi realizado no terço médio da pálpebra inferior, durante um minuto. A córnea foi dessensibilizada e a PIO mensurada com tonopen. A média do TLS-1 dos olhos direitos e esquerdo foi 11±5mm/min, não havendo diferença significativa entre os olhos (p=0,960). A média da PIO dos olhos direitos e esquerdo foi 20±6mmHg, não observando diferença entre os olhos direitos e esquerdos (p=0,836). Média STT-1 foi menor do que, e PIO foi o mesmo que os níveis normais em cães. Não houve diferença estatística na idade dos animais e valores STT-1 e da PIO. No presente trabalho, os níveis médios de guará STT-1 foram mais baixos em comparação com as observadas nos cães, enquanto que a pressão intraocular foi a mesma nos lobos guará como em cães. Devido ao aumento da incidência na prestação de cuidados de emergência para vítimas de lobos-guará atropelamentos e incêndios, determinar os valores de referência dos parâmetros oculares podem melhorar o diagnóstico correto e tratamento de doenças.(AU)

Purpose To measure the oral and pharyngeal transit time (OTT and PTT) in genetic syndromes. Methods Fourteen subjects, ranging in age from 4 months to 7 years, with different genetic diagnoses confirmed by clinical or laboratory examinations participated in this study. Real-time videofluoroscopic swallow study, and oral and pharyngeal transit times were analyzed using a specialized software. Descriptive and inferential statistical analyses were used. Results In the OTT analysis performed with liquid, of the 11 individuals evaluated, seven had normal OTT with an average of 0.75 s and four had altered OTT averaging 5.42 s. When swallowing a puree, four subjects showed normal OTT averaging 1.12 s and eight had altered OTT averaging 9.54 s. From the analysis of the PTT with liquid, seven had normal values averaging 0.68 s and four had altered PTT averaging 3.74 s. When swallowing a puree, four subjects had normal PTT averaging 0.75 s and eight had abnormal values averaging 3.98 s. Conclusion The oral and pharyngeal transit times may be normal or altered in the studied genetic syndromes. In this study, we found significant differences in transit times only in liquid consistency. .

Association between pharyngeal residue and posterior oral spillage with penetration and aspiration in stroke.

PURPOSE: This study aimed at showing association between the posterior oral spillage and pharyngeal residue with tracheal aspiration and/or laryngeal penetration in stroke. METHODS: Clinical cross-sectional retrospective multicenter study. The study included 63 videofluoroscopic tests of post-ischemic stroke individuals and oropharyngeal dysphagia data of the three reference centers providing care for patients with dysphagia (43 men and 20 women; age range: from 40 to 90 years). These individuals were divided into two groups. Group I consisted of 35 participants with the presence of penetration and/or laryngotracheal aspiration, and Group II consisted of 28 individuals with no penetration and/or aspiration. Videofluoroscopic swallowing test results were analyzed to divide the groups, and the presence of posterior oral spillage and pharyngeal residue was observed. RESULTS: No association was found between the groups with posterior oral spillage (χ²=1.65; p=0.30; φ²=0.02), but there was statistical difference for the association between pharyngeal residue (χ²=12.86; p=0.003; φ²=0.20) and the groups. CONCLUSION: There is an association between pharyngeal residue and penetration with tracheal aspiration in post-stroke individuals.

OBJETIVO: Este estudo teve por objetivo verificar a associação entre a ocorrência de escape oral posterior e a presença de resíduos faríngeos com penetração laríngea e/ou aspiração laringotraqueal no acidente vascular encefálico (AVE). MÉTODOS: Estudo clínico transversal, retrospectivo e multicêntrico. Foram incluídos neste estudo 63 exames videofluoroscópicos de indivíduos pós-AVE isquêmico e disfagia orofaríngea do banco de dados dos serviços de três centros públicos de referência no atendimento do indivíduo disfágico, sendo 43 do gênero masculino e 20 do gênero feminino, faixa etária variando de 40 a 90 anos. Estes foram divididos em dois grupos. O Grupo I foi composto por exames de 35 indivíduos com presença de penetração e/ou aspiração laringotraqueal e o Grupo II, por exames de 28 indivíduos com ausência de penetração e/ou aspiração. Foram analisados exames de videofluoroscopia da deglutição para dividir os grupos e observou-se a presença de escape posterior e resíduos faríngeos. RESULTADOS: Não houve associação entre os grupos com o escape oral posterior (χ2=1,65; p=0,30; φ2=0,02), porém houve associação entre resíduos faríngeos (χ2=12,86; p=0,003; φ2=0,20) e os grupos. CONCLUSÃO: Diante dos resultados obtidos, concluiu-se que há associação entre a presença de resíduos faríngeos com a ocorrência de penetração com aspiração laringotraqueal em indivíduos pós-AVE. .

Objetivo : analisar a acurácia da avaliação clínica da disfagia orofaríngea para detectar penetração e aspiração laringotraqueal na encefalopatia crônica não progressiva.Métodos : participaram deste estudo 45 indivíduos com ECNP e disfagia orofaríngea, sendo 28 do sexo masculino e 17 do sexo feminino, faixa etária variando de 3 a 19 anos. A avaliação clínica da deglutição utilizou protocolo específico e a videofluoroscopia de deglutição (VFD) foi utilizada como padrão ouro.Resultados : verificou-se que houve sensibilidade de 80,0% (IC 95%: [82,7;100]), especificidade de 46,67% (IC 95%: [18,1;75,3]), valor preditivo positivo de 77,78% (IC 95%: [62,8;92,8]) e valor preditivo negativo de 77,78% (IC 95%: [45,1;100]).Conclusão : constatou-se que a avaliação fonoaudiológica clínica da disfagia orofaríngea na ECNP apresenta maior sensibilidade que especificidade.

Análise quantitativa da deglutição orofaríngea em indivíduo gastrostomizado com Lipofuscinose Ceróide Neuronal: relato de caso / Quantitative analysis of oropharyngeal swallowing in Neuronal Ceroid Lipofuscinosis with gastrostomy: case report

A presença de disfagia orofaríngea infantil na população com afecções genéticas ainda é pouco estudada. O objetivo deste estudo foi analisar o tempo de trânsito oral total (TTOT) e o tempo de trânsito faríngeo (TTF) em um indivíduo com diagnóstico genético clínico de Lipofuscinose Ceróide Neuronal (LCN) com disfagia orofaríngea grave. Indivíduo com LCN, 3 anos de idade, gastrostomizado há dois anos e sem via oral parcial, histórico de déficit de ganho de peso anterior a via alternativa de alimentação, porém sem complicações pulmonares. A deglutição orofaríngea foi estudada por meio de videofluoroscopia de deglutição e análise quantitativa da deglutição com uso de software específico para tal avaliação. Na análise quantitativa do TTOT e TTF constatou-se, respectivamente, 45,37 segundos (padrão de normalidade em criança é de 4 segundos) e de 4,53 segundos para o TTF. Constatou-se significante aumento nos tempos de trânsito orofaríngeo neste indivíduo, sendo que a disfagia orofaríngea, parte do quadro desta criança com diagnóstico de LCN, deve ser investigada e acompanhada durante a evolução da doença. Uma avaliação da deglutição orofaríngea e acompanhamento nos indivíduos com esta condição genética deve ser realizada, considerando que essa alteração pode fazer parte do fenótipo desta condição e também pelo impacto que esse aumento nos tempos da deglutição pode ocasionar na condição nutricional e pulmonar desta população.

The presence of oropharyngeal dysphagia in the pediatric population with genetic diseases it is still poorly studied. The aim of this study was to analyze the oral total transit time and pharyngeal transit time, in an individual with neuronal ceroid lipofucinosis (NCL) with severe oropharyngeal dysphagia. Individual with NCL, 3 years old, 2 years with gastrostomy and no oral feeding, weighting loss, but without pulmonary complications. Oropharyngeal swallowing was studied by videofluoroscopy and it was realized a quantitative analysis using software. Changes were observed throughout the whole biomechanics of swallowing. The quantitative analysis of total oral transit time was found 45.37 seconds (default normality in children is 4 seconds) and for pharyngeal transit time was 4.53 seconds. It was found that beside the changes in the biomechanics of oropharyngeal swallowing in the case studied, an increase in total oral transit time and pharyngeal transit time was also observed, which can significantly compromise the nutritional status and pulmonary these individuals.
