ABSTRACT

Resumo Este trabalho é uma descrição de um caso clínico de paciente portador de Síndrome de Treacher Collins (STC). O paciente em questão é menor de idade e foi submetido a tratamento ortodôntico interceptivo de má oclusão de classe II, característica da síndrome devido à retrognatia, no Centro de Atenção e Pesquisa em Anomalia Craniofacial (CEAPAC), Cascavel ­ PR. As disostoses faciais são um conjunto de anomalias raras do esqueleto craniofacial, a mais comumente descrita é a STC, que é uma doença rara, sem predisposição por sexo ou raça. Os sintomas e a severidade desta síndrome diferem de indivíduo para indivíduo, mesmo entre membros da mesma família. Suas características comuns são as anormalidades dos pavilhões auriculares, hipoplasia dos ossos da face, obliquidade antimongolóide das fendas palpebrais com coloboma palpebral inferior e fissura palatina e o principal problema anatômico é a hipoplasia do terço médio da face e o hipodesenvolvimento da mandíbula e mento, o que leva o paciente portador desta síndrome apresentar por suas características faciais uma má oclusão de classe II muitas vezes associadas à mordida aberta, além de outros problemas orais como, por exemplo, as patologia das glândulas salivares, respiração bucal e apinhamento dentário. O tratamento ortodôntico intercepetivo do menor, embora após terminado tenha permanecido com má oclusão de classe II, obteve mudanças em parâmetros cefalométricos e faciais do paciente.(AU)


Abstract This work is a description of a clinical case of a patient with Treacher Collins Syndrome (CTS). The patient in question is younger and underwent interceptive orthodontic treatment of class II malocclusion, characteristic of the syndrome due to retrognathia, at the Center for Attention and Research in Craniofacial Anomaly (CEAPAC), Cascavel ­ PR. Facial dysostosis is a set of rare anomalies of the craniofacial skeleton, the most commonly described being CTS, it is a rare disease, without predisposition by sex or race. The symptoms and severity of this syndrome differ from individual to individual, even among members of the same family. Its common features are auricular pavilion abnormalities, facial bone hypoplasia, antimongoloid obliquity of the palpebral fissures with lower palpebral coloboma and cleft palate, and the main anatomical problem is hypoplasia of the middle third of the face and hypodevelopment of the mandible and chin, which Due to their facial characteristics, patients with this syndrome have a Class II malocclusion, often associated with an open bite, in addition to other oral problems such as salivary gland pathology, mouth breathing and dental crowding. The minor's interceptive orthodontic treatment, although after it ended, he remained with class II malocclusion, resulted in changes in the patient's cephalometric and facial parameters.(AU)

ABSTRACT

BACKGROUND: Cytokine-induced killer cells (CIKs) are an advanced therapeutic medicinal product (ATMP) that has shown therapeutic activity in clinical trials but needs optimization. We developed a novel strategy using CIKs from banked cryopreserved cord blood units (CBUs) combined with bispecific antibody (BsAb) blinatumomab to treat CD19+ malignancies. METHODS: CB-CIKs were expanded in vitro and fully characterized in comparison with peripheral blood (PB)-derived CIKs. RESULTS: CB-CIKs, like PB-CIKs, were mostly CD3+ T cells with mean 45% CD3+CD56+ and expressing mostly TCR(T cell receptor)αß with a TH1 phenotype. CB-CIK cultures had, however, a larger proportion of CD4+ cells, mostly CD56-, as well as a greater proportion of naïve CCR7+CD45RA+ and a lower percentage of effector memory cells, compared with PB-CIKs. CB-CIKs were very similar to PB-CIKs in their expression of a large panel of co-stimulatory and inhibitory/exhaustion markers, except for higher CD28 expression among CD8+ cells. Like PB-CIKs, CB-CIKs were highly cytotoxic in vitro against natural killer (NK) cell targets and efficiently lysed CD19+ tumor cells in the presence of blinatumomab, with 30-60% lysis of target cells at very low effector:target ratios. Finally, both CB-CIKs and PB-CIKs, combined with blinatumomab, showed significant therapeutic activity in an aggressive PDX Ph+ CD19+ acute lymphoblastic leukemia model in NOD-SCID mice, without sign of toxicity or graft-versus-host disease. The improved expansion protocol was finally validated in good manufacturing practice conditions, showing reproducible expansion of CIKs from cryopreserved cord blood units with a median of 28.8 × 106 CIK/kg. DISCUSSION: We conclude that CB-CIKs, combined with bispecific T-cell-engaging antibodies, offer a novel, effective treatment strategy for leukemia.

ABSTRACT

Introdução: O medo e a ansiedade são emoções preocupantes no consultório odontológico por desencadearem diferentes tipos de comportamento e causarem repercussões somáticas indesejáveis. A reversão do quadro de ansiedade ao tratamento odontológico requer intervenções de diferentes enfoques. Neste sentido, o papel do cirurgião-dentista no processo de redução dos efeitos negativos da ansiedade é essencial. Frente à importância da temática é desejável melhor se conhecer o fenômeno de ansiedade ao tratamento odontológico. Objetivo: identificar a influência de fatores sociodemográficos na determinação de ansiedade ao tratamento odontológico, junto a uma amostra de adultos residentes em Santa Catarina. Métodos: pesquisa descritiva, do tipo transversal, mediante levantamento de dados primários. A população-alvo foi constituída por adultos, residentes em três cidades da região oeste de Santa Catarina (Brasil) e uma cidade do litoral norte catarinense. O plano amostral foi não probabilístico e a obtenção da amostra deu-se por conveniência. A determinação do nível de ansiedade foi efetuada com base numa adaptação da escala de Corah - Dental Anxiety Scale (DAS). Resultados: a amostra constou de 1219 sujeitos, com idades variando de 18 a 87 anos. Os sujeitos classificados entre muito pouco a levemente ansioso (Grupo A - baixo nível) foram os mais frequentes (80 por cento) e 20 por cento eram portadores de moderada a extrema ansiedade (Grupo B - alto nível). A não efetivação de consultas de modo regular foi um pouco mais frequente entre os sujeitos do Grupo B. Conclusão: a maioria do grupo classificado com baixo nível de ansiedade (Grupo A) era de homens, da faixa etária de 50 ou mais anos e com grau de escolaridade superior.


Introduction: Fear and anxiety are disturbing emotions in the dental office for triggering different types of behavior and causing undesirable somatic repercussions. Reversal of anxiety disorders to dental treatment interventions requires different approaches. In this sense, the dentist's role in the reduction process of the negative effects of anxiety is essential. Considering the relevance of the theme it is desirable to understand clearly the anxiety phenomenon to dental treatment. Objective: to identify the influence of socio-demographic factors on the determination of anxiety related to dental treatment, in a sample of adults living in Santa Catarina. Methods: descriptive research, cross-sectional, through primary data collection. The target population consisted of adults living in two cities of the western region and one city of the north coast in Santa Catarina (Brazil). The sampling plan was not probabilistic and obtaining by convenience. To determine the level of anxiety was used an adaptation of Corah Scale - Dental Anxiety Scale (DAS). Results: The sample consisted of 1219 subjects, aged 18-87 years. The subjects rated between very little to look forward slightly (Group A - Low level) were the most common (80 per cent) and 20 per cent suffered from moderate to extreme anxiety (Group B - High level). The non-effective dental appointment was more frequent among subjects with high levels of anxiety (Group B). Conclusion: most in the group rated low anxiety (Group A) were men, older adults (50 or more years) and higher education. In the group with high levels of anxiety (Group B) the majority were women, young adults (18-24 years) and with higher education. The chi-square test revealed a significant association between anxiety and sexy and age.
