O comportamento de crianças durante atendimento odontológico

This research intended to investigate the use of diazepam in conjunction with behavioral strategies to manage uncooperative behavior of child dental patients. The 6 participants received dental treatment during 9 sessions. Using a double-blind design, children received placebo or diazepam and at the same time were submitted to behavior management produces (distraction, explanation, reinforcement and set rule and limits). All sessions were recorded in video-tapes biped in 15 seconds intervals, in which observers recorded child's (crying, body and/or head movements, escape and avoidance) and dentist's behavior. The results indicated that diazepam, considering the used dose, was only effective with one subject. The other participants didn't permit the treatment and showed an increase in their resistance. The behavioral preparation strategies for dental treatment should have been more precisely planned in order to help the child to face the real dental treatment conditions mainly in the first sessions avoiding to reinforce inappropriate behaviors.

O comportamento de crianças em tratamento odontológico: intervenção psicofarmacológica

The present investigation evaluated the effects of diazepam used to manage uncooperative behavior of child dental patients. Six participants received placebo or diazepam (0,3 mg/kg weight) before formal dental treatment at total 54 sessions that were all recorded in videotapes. The analysis of recorded child (crying, body and/or head movements, escape and avoidance) and dentist's behavior management procedures (distraction, explanation, positive reinforcement) indicates no differences by using a double-blind Wilcoxon design (p>0.05). It is suggested the necessity of methodological refinement in studies that combine psychological and pharmacological handling strategies.

Medo, ansiedade e controle relacionados ao tratamento odontológico

The aim of this study was to test fear, anxiety and control related to dental treatment. The subjects were 364 children with ages between 7 and 13 years. Three questionnaires with multiple choice questions were applied in groups of 10 children. The first instrument was the 15-item dental subscale from the Children’s Fear Survey Schedule9. The subjects rated their level of fear on a 5-point scale. The second survey instrument was the 20-item subscale from the State Trait Anxiety Inventory for Children16. This measure was used to capture how anxious the child was, in general. The third instrument was the Child Dental Control Assessment19. It contained 20 items to assess perceived control and 20 items to assess desired control. The results of the survey indicated that dental fear and anxiety were slightly higher for females when compared with male subjects (P < 0.05). Older children (11 to 13 years old) obtained higher fear scores than younger ones (7 to 9 years old). Concerning perceived control, the results indicate that younger children perceive more control than older ones. For desired control, the results indicate that younger children reported higher percentages than older ones. In this study, patients who had undergone anesthesia during treatment revealed higher fear scores when compared with those who had not. Dental fear etiology seems to be related to a procedure that may involve pain or lack of control.

Adesão de linhagem selvagem de Streptococcus thermophilus em superfície de aço inoxidável e efeitos da higienização na sua remoção

A wild strain of Streptococcus thermophilus isolated from pasteurized milk was evaluated using an experimental model with respect to its adhesion onto stainless steel surfaces and its behaviour when submitted to cleansing and sanification. In milk, the adhesion of the microorganism on to stainless steel surfaces was studied after 6 hours of contact at 45°C with agitation, and after a cleansing process involving cleaning stages with alkaline and acid detergents followed by sanification, in order to evaluate the resistance of the adhered cells. The microorganism adhered to stainless steel surfaces producing a cell load of 10(4) CFU/cm². After alkaline cleansing, no adhered cells were detected but 6 CFU/cm² were still detected on the surfaces after acid cleansing. Cleansing, followed by sanification with sodium hypochlorite, was sufficient to reduce the load of wild S. thermophilus on the stainless steel surfaces to non-detectable levels. The experimental model proved adequate for the study indicating that the wild microorganism S. thermophilus produces biofilms on stainless steel surfaces. Alkaline cleansing remove more that 99.9% of the adhered cells. The few cells adhered on the surface are removed by acid cleansing demonstrating the need to use different steps and types of detergent for efficient cleansing. The best results for the removal of these biofilms are obtained by using alkaline cleansing followed by acid cleaning, this procedure being more efficient when complemented by sanification with sodium hypochlorite.

Consenso brasileiro para a abordagem clínica e tratamento do hipotireoidismo subclínico em adultos: recomendações do Departamento de Tireoide da Sociedade Brasileira de Endocrinologia e Metabologia

INTRODUCTION: Subclinical hypothyroidism (SCH), defined as elevated concentrations of thyroid stimulating hormone (TSH) despite normal levels of thyroid hormones, is highly prevalent in Brazil, especially among women and the elderly. Although an increasing number of studies have related SCH to an increased risk of coronary artery disease and mortality, there have been no randomized clinical trials verifying the benefit of levothyroxine treatment in reducing these risks, and the treatment remains controversial. OBJECTIVE: This consensus, sponsored by the Thyroid Department of the Brazilian Society of Endocrinology and Metabolism and developed by Brazilian experts with extensive clinical experience with thyroid diseases, presents these recommendations based on evidence for the clinical management of SCH patients in Brazil. MATERIALS AND METHODS: After structuring the clinical questions, the search for evidence in the literature was initially performed in the MedLine-PubMed database and later in the Embase and SciELO - Lilacs databases. The strength of evidence was evaluated according to the Oxford classification system and established based on the experimental design used, considering the best available evidence for each question and the Brazilian experience. RESULTS: The topics covered included SCH definition and diagnosis, natural history, clinical significance, treatment and pregnancy, and the consensus issued 29 recommendations for the clinical management of adult patients with SCH. CONCLUSION: Treatment with levothyroxine was recommended for all patients with persistent SCH with serum TSH values > 10 mU/L and for certain patient subgroups.

Association of insulin resistance and GLP-2 secretion in obesity: a pilot study

OBJECTIVE: The objective of this pilot study was to determine whether glugagon-like peptide 2 (GLP-2) secretion relates to insulin sensitivity (IS) in obese subjects. SUBJECTS AND METHODS: Twenty four obese subjects [body mass index (BMI) 40.0 ± 3.0 kg/m² (mean ± standard deviation)] were included, nine of which were male, age 43 ± 8 years. Twelve subjects had type 2 diabetes, all treated with oral anti-diabetic agents only. The subjects were submitted to standard meal tolerance test (MTT) for dosage of the curves: glucose, insulin, and GLP-2. Insulin sensitivity was measured by HOMA-IR, and OGIS was derived from the MTT. Spearman linear correlations and partial correlations were obtained. RESULTS: There was an inverse relationship between the GLP-2 secretion and IS: HOMA-IR correlated with GLP-2 AUC (R = 0.504; p = 0.012), and OGIS correlated with GLP-2 incremental AUC (R = -0.54; p = 0.054). The correlation persisted after controlling for BMI. CONCLUSION: We found an association of GLP-2 secretion and insulin resistance (IR). The understanding of the underlying mechanisms may provide future directions in the pharmacological manipulation of incretins, and in the treatment of obesity and related metabolic disorders.

Tratamento da retinopatia diabética: percepções de pacientes em Rio Claro (SP) - Brasil

PURPOSE: To collect information and opinions from a group of diabetic patients regarding diabetic retinopathy and its treatment, in order to get reliable information that can help to improve programs and actions to control and prevent this ocular disease. METHODS: A cross-sectional study was performed. The sample was from 980 diabetic patients seen in a diabetic association. A previous questionnaire was made with general questions about the main subject. Thereafter, an appropriate questionnaire was prepared. RESULTS: The sample showed that among 299 patients with age ranging from 16 to 83 years, with a mean of 57 years, mainly female (67.91%) did not know how severe their disease was (30.8%), or believed that it was not a serious problem (19.7%). The laser technique to solve diabetic retinopathy was known by 60.2% of the patients. It was reported as the only treatment available by 24.1%. Among the reasons for no treatment 59.8% reported that they did not think it was necessary and 29.7% could not afford it. CONCLUSIONS: Patients showed lack of knowledge about how serious is diabetic retinopathy, the possibility of using laser technique for it and the severity of the disease. Some patients believed in the efficacy of the treatment and some patients did not, but all of them reported that they were afraid of submitting to it.

Derivação ventriculoperitoneal com válvula no tratamento da hidrocefalia infantil

From December-1965 to November-1969, 95 hydrocephalic infants have been operated upon using ventriculoperitoneal shunt with valve (88 cases with a Spitz-Holter valve, 6 cases with a Hakim valve and one case with a Pudenz-Heyer valve). Up to the present time (December, 1970) a total of 54 children are alive with a compensated hydrocephalus and 9 patients died, being impossible to follow-up the 32 remaining cases. The use of the ventriculoperitoneal shunt has eliminated all cardiovascular-pulmonary complications and reduced the number for surgical revisions. Besides, infections involving the draining system are less severe and more easily controlled than those occurring in the ventriculoatrial shunts. After analysis of the surgical techniques as well as complications and results the following conclusions are stated: 1) the use of a valve in the ventriculoperitoneal shunt difficults the oclusion of the peritoneal end of the draining system; 2) good results can be expected without reoperations in about 42,35% of hydrocephalus cases treated by ventriculoperitoneal shunt with valve; 3) ventriculoperitoneal shunts with valve showed better results when compared to ventriculoatrial shunts. This statement is made comparing two groups of hydrocephalic infants submitted to surgery at the same Service and in the same conditions, with the same follow-up period; 4) the cases presented permit to state that at present time the ventriculoperitoneal shunt with valve is the most suitable surgical procedure for hydrocephalus.

Tratamento dos abscessos intracranianos por trepanopunção

The cases of nine pacients with intracranial abscess operated on by aspiration are reported. Only one patient did not survive. One pacient developed postoperative seizures and, another, hemiparesis. In 5 cases it was necessary a relief of increased intracranial pressure by neurosurgical emergency.

Tratamento clínico da epilepsia resistente

The authors analysed 34 cases of resistant epilepsy (20 males and 14 females, mean age 23 years), treated clinically between February/1984 and May/1986. The patients underwent neurological, neuropsychological, psychological, psychiatric, cerebrospinal fluid, electroencephalographic, tomographic and/or angiographic examination. Most of the patients had complex partial seizures. The etiology was unknown in 19 patients (55.8%), probable neurocysticercosis in 6, perinatal hypoxia in 5, delivery trauma in 3 and probable sequelae of encephalitis in 2 patients. There was a clear past history of infantile febrile convulsion in 2 patients. Most patients received carbamazepine (mean dose 24.5 mg/kg/day), phenytoin (5 mg/kg and valproic acid (28 mg/kg) as monotherapy or in association. Twenty-two patients (64.7%) had more than 80% decrease of the seizure frequency. Nine resistant epilepsy-cases (24.5%) were evaluated as candidates for surgical therapy. The authors concluded that the resistant epilepsy is best managed by a specialised, multidisciplinary team, and pointed out the need of a correct diagnosis of the seizure type, an adequate drug therapy and a good engagement of the patient and his family in the treatment.

Efeitos do aparelho Jasper Jumper no tratamento da má oclusão de Classe II

OBJETIVO: o objetivo deste estudo foi avaliar os efeitos esqueléticos e dentoalveolares do tratamento de pacientes com má oclusão de Classe II com o aparelho Jasper Jumper associado ao aparelho ortodôntico fixo, comparados a um grupo controle não-tratado. MÉTODOS: a amostra foi constituída por 47 indivíduos, divididos em dois grupos: Grupo 1, contendo 25 pacientes com idade média de 12,72 anos, tratados com o aparelho Jasper Jumper por um tempo médio de 2,15 anos; Grupo 2 (controle), composto por 22 indivíduos com idade média de 12,67 anos, não-submetidos a tratamento ortodôntico e com má oclusão de Classe II, observados por um período médio de 2,12 anos. Foram avaliadas as telerradiografias ao início e ao final do tratamento ortodôntico para o Grupo 1 e do período de observação para o Grupo 2. As variáveis cefalométricas iniciais, finais e as alterações com o tratamento foram comparadas entre os grupos por meio do teste t independente. RESULTADOS: em comparação ao grupo controle, o grupo Jasper Jumper apresentou maior restrição do deslocamento anterior da maxila e maior retrusão maxilar, melhora da relação maxilomandibular, diminuição da convexidade facial, maior protrusão e intrusão dos incisivos inferiores e maior extrusão dos molares inferiores, além de maior diminuição dos trespasses horizontal e vertical e maior melhora da relação molar. CONCLUSÃO: a correção da Classe II no grupo tratado com o Jasper Jumper e aparelhagem fixa se deu principalmente devido à restrição do crescimento maxilar, protrusão e intrusão dos incisivos inferiores e extrusão dos molares inferiores.

Tratamento ortopédico com aparelho de Herbst: ocorrem mudanças verticais no padrão de crescimento facial?

OBJETIVO: o objetivo deste estudo prospectivo de 32 adolescentes com má oclusão de Classe II, divisão 1, associada a retrognatismo mandibular, tratados com aparelho de Herbst, construído sobre bandas e coroas metálicas, foi avaliar cefalometricamente as possíveis mudanças no padrão de crescimento facial. METODOLOGIA: as telerradiografias laterais foram obtidas ao início do tratamento (T1) e imediatamente após 12 meses de tratamento com o referido aparelho ortopédico (T2). Foram utilizados o quociente de Jarabak e o VERT de Ricketts (modificado) para determinação do padrão facial em T1 e T2. RESULTADOS: utilizando o quociente de Jarabak, os resultados evidenciaram que 27 casos (84,4%) apresentaram padrões hipodivergentes em T1 e permaneceram da mesma forma em T2. Cinco casos (15,6%) apresentaram padrão neutro em T1 e não exibiram mudanças em T2. Quando avaliado o VERT de Ricketts (modificado), não ocorreram mudanças no padrão facial em 31 pacientes. Em apenas um caso ocorreu mudança do tipo facial. CONCLUSÃO: baseado nos resultados obtidos, pode-se concluir que, após 12 meses de tratamento com aparelho de Herbst, não ocorreram mudanças verticais no padrão de crescimento facial dos pacientes estudados.
