ABSTRACT

Abstract This split-mouth randomized controlled trial aimed to evaluate the primary and secondary stability of hybrid implants with different thread configurations and hydrophilic surfaces. Twenty patients with a partially edentulous maxilla were selected. These patients received two types of implants with the same hydrophilic surface: CTP group: Cylindrical-Tapered implant with perforating threads; CTH: Cylindrical-Tapered implant with hybrid threads configuration (perforating and condensing threads). The primary and secondary stability parameters were measured by insertion torque and resonance frequency analysis at the time of implant placement and 7, 28, 56, and 90 days after the surgical procedure. The paired t-test was used to compare the data on the implant's stability between the groups. The statistical analysis was performed with a confidence level set at 95%. It was found that the implants in the CTH group presented higher primary stability values ​​at the time of implant placement, due to the higher ISQ (63.61 ± 9.44 vs. 40.59 ±7.46) and insertion torque (36.92 ± 16.50 Ncm vs. 28.00 ± 14.40 Ncm), than the implants in the CTP group. The CTH group presented higher ISQ values ​​in all follow-up periods: 7 days (68.67 ± 7.60 vs. 41.55 ± 9.07), 28 days (68.61 ± 5.98 vs. 47.90 ±13.10), 56 days (74.09 ± 3.96 vs. 55.85 ± 13.18), and 90 days (75.45 ± 4.02 vs. 63.47 ± 6.92) after implant placement. Hybrid implants with perforating and condensing threads demonstrated greater stability than hybrid implants with only perforating threads.


Resumo O objetivo deste estudo controlado randomizado de boca dividida foi avaliar a estabilidade primária e secundária de implantes híbridos com diferentes configurações de rosca e superfícies hidrofílicas. Vinte pacientes com maxila parcialmente edêntula foram selecionados. Esses pacientes receberam dois tipos de implantes com a mesma superfície hidrofílica: Grupo CTP: Implante cilíndrico-cônico com roscas perfurantes; Grupo CTH: Implante cilíndrico-cônico com roscas perfurantes e condensadoras. Os parâmetros de estabilidade primária e secundária foram medidos por análise de torque de inserção e frequência de ressonância no momento da colocação do implante e 7, 28, 56 e 90 dias após o procedimento cirúrgico. O teste t-pareado foi utilizado para comparação dos dados de estabilidade entre os grupos. A análise estatística foi executada levando-se em consideração um nível de confiança de 95%. Constatou-se que os implantes do grupo CTH apresentaram maiores valores de estabilidade primária no momento da colocação do implante, devido ao maior ISQ (63.61 ± 9.44 vs. 40.59 ±7.46) e torque de inserção (36.92 ± 16.50 Ncm vs. 28.00 ± 14.40 Ncm), do que os implantes do grupo CTP. Implantes do grupo CTH apresentaram valores de ISQ superiores em todos os períodos de acompanhamento: 7 dias (68.67 ± 7.60 vs. 41.55 ± 9.07), 28 dias (68.61 ± 5.98 vs. 47.90 ±13.10), 56 dias (74.09 ± 3.96 vs. 55.85 ± 13.18) e 90 dias (75.45 ± 4.02 vs. 63.47 ± 6.92). Os implantes híbridos com roscas perfurantes e condensantes demonstraram maior estabilidade do que os implantes híbridos com apenas roscas perfurantes.

ABSTRACT

Resumen La asociación entre parálisis cordal y nódulo tiroideo es sugestiva de malignidad; por lo general, se trata de un carcinoma de la glándula tiroides con un tumor avanzado. Presentamos el caso de una paciente con carcinoma papilar de tiroides, parálisis cordal izquierda con aspiración bronquial y complicaciones pulmonares severas, a quien se le realizó hemitiroidectomía izquierda más tiroplastia con anestesia local y control endoscópico utilizando injerto de politetrafluoroetileno en forma artesanal. La evolución quirúrgica mostró buen resultado a corto plazo (13 meses), sin complicaciones relacionadas, fonación aceptable, con ganancia ponderal y sin nuevas complicaciones pulmonares. No existen hasta el momento de realizar este manuscrito reportes de cirugía de tiroides más tiroplastia con anestesia local. Se requiere una serie con mayor número de casos para llegar a conclusiones de validez.


Abstract The association between chordal paralysis and thyroid nodule is suggestive of malignancy, and it is usually a carcinoma of the thyroid gland with an advanced tumor. We present the case of a patient with papillary carcinoma of the thyroid, left cordal paralysis with bronchial aspiration and severe pulmonary complications who underwent left hemithyroidectomy plus thyroplasty with local anesthesia and endoscopic control using handcrafted polytetrafluoroethylene graft. The surgical evolution showed good short-term results (13 months) without related complications, acceptable phonation, with weight gain and without new pulmonary complications. There are no reports of thyroid surgery plus thyroplasty with local anesthesia at the time of this manuscript. A series with a greater number of cases is required in order to draw valid conclusions.

ABSTRACT

Resumo O objetivo deste estudo foi avaliar a prevalência e a severidade de fluorose dentária em escolares de 11 a 14 anos de idade em Teresina (PI) Brasil, município de clima tropical com água de abastecimento público fluoretada. Estudo do tipo observacional transversal no qual foram avaliadas 571 crianças distribuídas nas redes pública e particular de ensino. A coleta de dados foi realizada nas unidades escolares, após recolhimento do Termo de Consentimento Livre e Esclarecido (TCLE) e questionário respondido pelos pais referentes às condições socioeconômicas e demográficas e aos hábitos de higiene bucal. O exame dentário foi realizado por um cirurgião-dentista calibrado. O índice aplicado foi o Thylstrup e Fejerskov (TF). A prevalência de fluorose foi de 77,9%, e apenas 12,5% das crianças acometidas apresentaram TF ≥ 3, grau com comprometimento estético. Os pré-molares foram os dentes mais afetados pela fluorose. Dentre os escolares com maior severidade de fluorose, 98,6% dos pertenciam à classe social mais baixa (>B2), 91,5% nasceram e sempre moraram em Teresina, 94,4% consumiam água de abastecimento fluoretada, 76% usaram dentifrício infantil e 64% as mães relataram que engoliam dentifrício. A prevalência de fluorose foi elevada, mas com baixa severidade, em indivíduos expostos à fluoretação desde o nascimento.


Abstract The scope of this study was to evaluate the prevalence and severity of dental fluorosis among 11 to 14-year-old schoolchildren in Teresina, Piauí, Brazil, which is a tropical city with a fluoridated public drinking water supply. It involved a cross-sectional observational study on a sample of 571 students in public and private schools. Informed Consent forms were approved for the data collection and the exams were conducted at the schools. Data were recorded on a questionnaire answered by the parents, regarding the socioeconomic and demographic characteristics and oral hygiene habits of the sample. The dental exam was performed qualified dental sugeons. The Thylstrup-Fejerskov (TF) index was used. The prevalence of fluorosis was 77.9%, and only 12.5% of the affected children had TF ≥ grade 3 (with aesthetic damage). The premolars were the teeth most affected by fluorosis. Among the students with the highest severity of fluorosis, 98.6% belonged to the lowest social bracket (> B2), 91.5% were born and had always lived in Teresina, 94.4% consumed water from the fluoridated public supply, 76% used toothpaste for children and 64% of mothers reported that they swallowed toothpaste. The prevalence of fluorosis was high, though the severity was low in individuals exposed to fluoridation since birth.

ABSTRACT

Objective: To evaluate the surface hardness of a national glass ionomer cement with increased powder / liquid ratio, suitable for the atraumatic restorative treatment technique. Material and Methods: This is a study of the quantitative experimental type, in which 30 specimens were made and divided equally into 03 experimental groups (glass ionomer cement restorative Vitro Molar -DFL in the proportion specified by the manufacturer; glass ionomer cement restorative Vitro molar ratio -DFL modified with incorporation of 50% powder; and Gold Label 9 - GC Corporation in the proportion specified by the manufacturer). After handling, the materials were placed in a Teflon mold for manufacturing the cylindrical samples (5mm x 2 mm), with the aid of a Centrix syringe (Centrix, Shelton, CT, USA). Specimens were stored in liquid petroleum jelly at a temperature 37 ° ± 1 for up to 7 days. The specimens were evaluated by Vickers hardness test at time intervals of 24 hours and 7 days after manufacture. The data were subjected to the Independent Student's-t tests and analysis of variance (ANOVA), and subsequently by Tukey's test at 95% level of significance. Results: The setting time positively influenced the hardness of the two glass ionomer cements (p<0,001). Cement Gold Label 9 showed higher hardness values than cement Vitro Molar (p<0,001), irrespective of the evaluation time interval. The latter in turn, showed improved values when manipulated with the modified powder / liquid ratio (3: 2) (p<0,001). Conclusion: Vitro Molar glass ionomer cement showed higher hardness values when manipulated with the modified powder/liquid ratio.

ABSTRACT

O presente artigo constrói uma reflexão acerca do lugar da imagem na clínica psicanalítica. Apresenta-se brevemente a questão do olhar e da imagem na teoria psicanalítica por meio de dois conceitos primordiais: o de fantasia e o de fetiche. Ambos são construções imagéticas que carregam em sua estrutura as marcas das tensões intrapsíquicas que os moldam e caracterizam a dimensão da imagem na análise. Propõe-se uma concepção do tratamento psicanalítico como incidindo no espaço entre imagem e palavra, e aproxima-se tal concepção do conceito de montagem cinematográfica. O tratamento analítico teria por visada, por meio do manejo da transferência, remontar a narrativa sintomática do sujeito em análise


The present article analyses the role of image in the psychoanalytic practice. The subject of image is dealt with through two main concepts: fantasy and fetish. Both are constructs of images that contain in their structures the marks of the inner psychic tensions that shape them, and through that they characterize the dimension of image in psychoanalysis. A conception of the psychoanalytic treatment as a form of clinic that dwells in the space between images and words is proposed, as well as a parallel between such practice and cinematographic montage. The goal of psychoanalytic treatment would be, thus, remaking the montage of the symptomatic narrative of the subject undergoing psychoanalysis, through the handling of transference.

ABSTRACT

Se estudiarion dieciocho lactantes menores de un añofallecidos por una infección respiratoria baja (IRB): neumonitis, neumonía o bronconeumonía (grupo de estudio) y un grupo control (n=18) con igual diagnóstico y sobrevivientes, apareados por edad y sexo, internados en el Hospital de Pediatría Garrahan entre 1987 y 1989. Se comprobó que la mayoría de los casos provenía de áreas con alto porcentaje (>30 por ciento) de familias con necesidades básicas insatisfechas (NBI). Hubo, en ambos grupos, elevada frecuencia de antecedentes adversos en la salud materno-infantil: embarazo no controlado (n=6), desnutrición (n=19), vacunación incompleta (n=15) e internaciones previas por infecciones respiratorias (n=9) siendo la frecuencia de las tres últimas variables desfavorables significativamente mayor en el grupo de estudio. En la mayoría de los casos (n=24) la evoluci'on ambulatoria de la IRB fue de 3 o más días; todos presentaron durante esta etapa dificultad respiratoria, pero sólo en el grupo fallecido tos cianozante (n=7) y apneas (n=4). A pesar de estos signos, la mayoría de los pacientes (n=29) fue atendida ambulatoriamente. Los pacientes fallecidos presentaron mayor gravedad al ingreso, expresada por una mayor frecuencia de hipercapnia (n=16), estadísticamente significativa. En la anatomía patológica predominó la bronconeumonía bacteriana inespecífica, asociada, en algunos casos, a sepsis y neumonitis viral. Estos resultados demuestran que en la población internada por IRB existe una elevada frecuencia de antecedentes adversos, siendo éstos más frecuentes y severos en el grupo fallecido. Asimismo se comprobó insuficiente atención de la enfermedad actual, no relacionada en sus acciones con los factores de riesgo ni con la severidad de los signos presentes. Los resultados señalan la necesidad de generar acciones preventivas y curativas que reorganicen y mejoren el sistema de atención materno-infantil a fin de disminuír la mortalidad infantil debida a IRB.
