Treatment of trapeziometacarpal osteoarthritis with a pyrocarbon implant: long-term results.

OBJECTIVE: Trapeziometacarpal osteoarthritis is the second most common degenerative articular disease. Although initial therapy should be conservative, surgical treatment is often required. Several surgical techniques have been described, but none has proved to be a gold-standard. The objective of this study was to evaluate the long-term clinical and radiological results of trapeziometacarpal interposition arthroplasty with the PyroDisk implant (Integra LifeSciences). METHODS: A retrospective long-term study of all patients who underwent trapeziometacarpal interposition arthroplasty with a pyrocarbon implant at our institution was performed. RESULTS: Twenty-four patients who underwent PyroDisk (Integra LifeSciences). arthroplasty at our institution were identified; 7 were lost to follow-up; 17 patients were evaluated, for 20 arthroplasties. Mean follow-up was 13.5 years (range: 12 to 15 years). Disability in daily living activities was low (mean Disabilities of the Arm, Shoulder and Hand score, 29.6), with a mean pain score of 0.22. Mean Kapandji score at 13.5 years was 8.63. Mean grip strength was 18.5 kg and key-pinch strength 2.84 kg. Two patients had implant dislocation, needing revision surgery for implant removal. Implant survival rate was 88.9% at 13.5 years. CONCLUSIONS: Our study confirmed that good clinical results can be expected after interposition arthroplasty with PyroDisk (Integra LifeSciences). Regarding radiological findings, peri-implant osteolysis was present in 12 of the patients, but had no influence on the clinical outcome.

Higher age, female gender, osteoarthritis and blood transfusion protect against periprosthetic joint infection in total hip or knee arthroplasties: a systematic review and meta-analysis.

PURPOSE: The goal of this systematic review and meta-analysis was to identify the main risk factors for periprosthetic joint infection (PJI) in patients undergoing total hip or knee arthroplasties. METHODS: A systematic review was conducted of the potential risk factors for PJI in total hip or total knee arthroplasty. Risk factors were compared and grouped according to demographics, comorbidities, behavior, infections, native joint diseases and other patient-related and procedure-related factors. Meta-analysis (random-effects models) was conducted using odds ratio (OR) and mean difference (MD). Risk of bias (ROBBINS-I) and strength of the evidence (GRADE) were assessed. RESULTS: The study included 37 studies (2,470,827 patients). Older age was a protective factor (MD = - 1.18). Male gender (OR 1.34), coagulopathy (3.05), congestive heart failure (2.36), diabetes mellitus (1.80), obesity (1.61), systemic neoplasia (1.57), chronic lung disease (1.52), and hypertension (1.21) increased the risk for PJI. Behavioral risk factors comprised alcohol abuse (2.95), immunosuppressive therapy (2.81), steroid therapies (1.88), and tobacco (1.82). Infectious risk factors included surgical site infections (6.14), postoperative urinary tract infections (2.85), and prior joint infections (2.15). Rheumatoid arthritis, posttraumatic native joint disease, high National Nosocomial Infections Surveillance (NNIS) system surgical patient index score, prior joint operation, American Society of Anesthesiologists score ≥ 3 and obesity were also significantly associated with higher risk of PJI. Osteoarthritis and blood transfusion were protective factors. CONCLUSIONS: The main risk factors for PJI in each category were male gender, coagulopathy, alcohol abuse, surgical site infection (highest score) and high NNIS system surgical patient index score. Protective factors were age, female gender in TKA, osteoarthritis and blood transfusion. Optimization of modifiable risk factors for PJI should be attempted in clinical practice. LEVEL OF EVIDENCE: II.

[The Epidemiological Profile of the Isolation of 'Problem' Microorganisms]. / Perfil Epidemiológico dos Isolamentos dos Microrganismos 'Problema'.

INTRODUCTION: Infections are a major problem and the presence of drug-resistant microorganisms has significant clinical and economic impact. The present study aims to evaluate the epidemiological profile of "problem" microorganisms isolated in a hospital in the north of Portugal. MATERIAL AND METHODS: All isolated microorganisms were analyzed, between January 2014 and June 2015. Data obtained was then processed using statistical software. RESULTS: We analyzed 8146 microbiological isolations and found a prevalence of 23% of 'problem' microorganisms (in descending order of frequency: Enterococcus, Pseudomonas, Staphylococcus aureus e Streptococcus pneumonia), 57.55% of which isolated in male patients. The most frequent mechanism of drug resistance for the overall sample was the production of extended-spectrum beta-lactamase, and resistance to oxacillin for 'problem' microorganisms. DISCUSSION: In this sample, we observed a much higher prevalence of 'problem' microorganisms than that reported in other countries, which shows the need of improvement of surveillance mechanisms and treatment of these cases. Microorganisms that showed higher resistance were Staphylococcus aureus (resistant to oxacillin) and Enterococcus (resistant to vancomycin). Those were isolated in patients with a higher mean age compared to non-resistant microorganisms. Most of these microorganisms were isolated in hospitalized patients or intermediate and intensive care units, what relates them with healthcare associated infections. CONCLUSION: The prevalence of infection by 'problem' microorganisms during the studied period was 23%. The detection and control of the spread of these microorganisms are paramount due to its impact on health costs, morbidity and survival of patients.

Introdução: As infeções são um problema cada vez mais frequente e a presença de microrganismos resistentes cria impacto clínico e económico. Este estudo tem por objetivo determinar o perfil epidemiológico dos microrganismos 'problema' isolados num hospital do norte de Portugal.Material e Métodos: Foram analisados todos os isolamentos microbiológicos, entre janeiro de 2014 a junho de 2015. Os dados foram tratados em software estatístico.Resultados: Analisaram-se 8146 isolamentos microbiológicos, nos quais se obtiveram 23% de isolamentos de microrganismos 'problema' (por ordem decrescente de frequência: Enterococcus, Pseudomonas, Staphylococcus aureus e Streptococcus pneumonia), sendo 57,55% em doentes do sexo masculino. O mecanismo de resistência mais frequente foi a produção de betalactamase de espectro estendido no global dos isolamentos e a resistência à oxacilina nos microrganismos 'problema'.Discussão: Nesta amostra, observou-se uma incidência bastante superior de microrganismos problema àquela publicada noutros países, o que remete para a necessidade da melhoria de mecanismos de vigilância e tratamento destes casos. Os microrganismos que apresentaram mais resistências foram o Staphylococcus aureus (resistente à oxacilina) e o Enterococcus (resistente à vancomicina), tendo-se verificado que a média de idades nestes casos era superior à dos não resistentes. A maioria destes microrganismos foi isolada no internamento e unidades de cuidados diferenciados, o que os relaciona a infeções associadas aos cuidados de saúde.Conclusão: A prevalência de infeção por microrganismos 'problema' no período estudado foi de 23%. É importante a deteção e o controle da disseminação destes microrganismos pelo seu impacto nos custos em saúde, morbilidade e sobrevida dos doentes.

What Increases the Risk of Dental Traumatism in Patients with Developmental Disabilities?

This study investigated risk factors for tooth injuries in individuals from a dental clinical reference service for patients with special needs in Belo Horizonte, MG, Brazil. This is a retrospective cohort study that evaluated 493 dental charts of individuals with or without tooth injuries at their first dental appointment. The dependent variable was the time of occurrence of new dental traumatic injuries and was measured in months. Gender, age, International Code of Diseases, mother's education, mouth breathing, hyperkinesis, pacifier use, thumb sucking, psychotropic drug use, tooth injuries at the first dental examination, involuntary movements, open bite, having one or more siblings and reports of seizures were the covariates. The Cox proportional hazards regression model was used to estimate the unadjusted and adjusted hazard ratios and their respective 95% confidence intervals. The average time that individuals remained free of dental traumatism was 170.78 months (95% CI, 157.89-183.66) with median of 216 months. The incidence of new events was 11.88%. The covariate associated with an increased risk of dental traumatism was a history of tooth injuries at the first dental appointment. The increase in dental trauma risk was 3.59 (95% CI, 1.94-6.65). A history of traumatic dental injury was the risk factor for the dental trauma found in this group of individuals with developmental disabilities.

Factors associated with anterior open bite in children with developmental disabilities.

AIM: To investigate factors associated with anterior open bite in individuals aged from 2 to 33 years with developmental disabilities. DESIGN: This is a cross-sectional study. A total of 271 dental records were examined. The anterior open bite analyzed was determined based on clinic exam. These variables were also analyzed: gender, age, education level of mother, International Code of Diseases (ICD), mouth breathing, use of anticonvulsant drugs, hyperkinesis, pacifier use, thumb sucking, seizure, and involuntary movements. For the purposes of analysis, the individuals were categorized as being with and without anterior open bite. Variables with a p-value of < 0.25 in the bivariate analysis were incorporated into the logistic regression models. RESULTS: Mouth breathers had a 2.60-fold (95% CI: 1.35-5.01) greater chance of exhibiting anterior open bite than nasal breathers. Pacifier users are more likely to have an anterior open bite (3.32-fold, 95% CI: 1.62-6.77). Individuals with reported involuntary movements had a 2.66-fold (95% CI: 1.26-5.63) greater chance of exhibiting anterior open bite. Users of anticonvulsants drugs had a 3.05 (95% CI: 1.57-5.92) greater chance of showing anterior open bite. CONCLUSION: Involuntary movements, mouth breathing, using anticonvulsant drugs, and using pacifier are factors associated with anterior open bite in patients with developmental disabilities.

Regional differences in infection control conditions in a sample of primary health care services in Brazil.

International guidelines have pointed out the importance of the physical environment of health care facilities in preventing and controlling infection. We aimed to describe the physical environment of dental care facilities in Brazil in 2014, focusing on characteristics designed to control infections. Exactly 16,202 dental offices in the Brazilian Unified National Health System (SUS) participated in this survey. Trained researchers extracted information about the infection control characteristics of health facilities by using a structured instrument. We used data from 12 dichotomous questions that evaluated the wall, floor, sink and tap conditions, and the presence and condition of sterilization equipment. We calculated a score by summing the number of characteristics handled appropriately for infection control, which could range from 0 to 12. Hierarchical cluster analyses were developed. None of the 12 criteria were met by all the oral health teams. Only 208 (1.3%) dental offices correctly performed all 12-infection control practices. Two clusters, with different frequencies of structure for infection control in dental offices, were identified. South and Southeast regions had the highest frequencies for Cluster 1, with better structure of infection control in dental offices. Dental care facilities of oral health teams were not typically meeting the infection control guidelines regarding clinic design and equipment. Adherence to the guidelines varied among the Brazilian geographic regions.

As diretrizes internacionais destacam a importância do ambiente físico dos serviços de saúde para prevenir e controlar as infecções. Procuramos descrever o ambiente físico em serviços de saúde bucal no Brasil em 2014, com enfoque nas características programadas para controlar as infecções. Precisamente 16.202 consultórios odontológicos no Sistema Único de Saúde (SUS) participaram na pesquisa. Pesquisadores treinados coletaram informações sobre as características do controle de infecções nesses serviços de saúde, utilizando um instrumento padronizado. Utilizamos dados de 12 perguntas dicotômicas que avaliavam as condições das paredes, piso, pia e torneira e a presença e as condições do equipamento de esterilização. Calculamos um escore pela soma do número de características administradas adequadamente para o controle de infecções, variando de 0 a 12. Foram desenvolvidas análises hierárquicas de clusters. Nenhum dos 12 critérios foi atendido por todas as equipes de saúde bucal. Apenas 208 (1,3%) dos consultórios odontológicos realizavam todas as 12 práticas de controle de infecções. Foram identificados dois clusters com distintas frequências de estruturas para controle de infecções nos consultórios odontológicos. As regiões Sul e Sudeste mostraram as maiores frequências no Cluster 1, com melhor estrutura de controle de infecções nos consultórios odontológicos. De maneira geral os serviços de saúde bucal não atendiam as diretrizes para o controle de infecções, referentes à planta física e equipamento dos consultórios. A aderência às diretrizes variava de acordo com a região do país.

Calculamos una puntuación para la suma del número de características administradas adecuadamente para el control de infecciones, variando de 0 a 12. Se desarrollaron análisis jerárquicos de clúster. Ninguno de los 12 criterios fue observado por todos los equipos de salud bucal. Solamente 208 (1,3%) de los consultorios odontológicos realizaban las 12 prácticas de control de infecciones al completo. Se identificaron dos clústeres con distintas frecuencias de estructuras para el control de infecciones en los consultorios odontológicos. Las regiones Sur y Sudeste mostraron las mayores frecuencias en el Clúster 1, con una mejor estructura de control de infecciones en los consultorios odontológicos. De manera general, los servicios de salud bucal no atendían a las directrices para el control de infecciones, referentes a las instalaciones físicas y equipamiento de los consultorios. La adherencia a las directrices variaba de acuerdo con la región del país.

Oral Health Status among Girls with Developmental Disabilities: A Cluster Analysis

Objective: To investigate the factors that influence oral health of girls, with developmental disabilities, attended by a dental service. Material and Methods: A Cross-sectional epidemiological study was carried out using information collected from 171 dental charts of children aged one to 13 years, with developmental disabilities who were treated between 1998 and 2013. Studied variables were: dental caries, gingivitis, bruxism, xerostomia, ingestion of cariogenic food and oral hygiene. Statistical analysis was performed using proportion calculations of each variable and by cluster analysis. Results: Three types of clusters were formed from girls based on three variables (presence of dental caries, gingivitis and bruxism). The choice of two clusters was due to a better understanding of the phenomenon (oral conditions). There was an average of 0.77 of deciduous and 0.21 permanent decayed teeth. Cluster 1 is composed of younger children with lower caries and gingivitis experiences; lower proportion of xerostomia and ingestion of cariogenic food, higher proportion of good oral hygiene and more bruxism experience. Conclusions: Dental caries and gingivitis among girls with developmental disabilities are influenced by factors whose relation of cause and effect has been discussed in the literature. Bruxism is a protective factor against these diseases.Results reinforce the need for early preventive interventions in this population.

Perfil dos pacientes com deficiências de desenvolvimento sob atendimento odontológico em um projeto de extensão intersetorial / Profile of patients with developmental disabilities under dental care in an intersectoral extension project

Objetivo: Descrever o perfil dos pacientes atendidos em uma instituição filantrópica onde funciona o projeto de extensão "Atendimento Odontológico a Pacientes com Necessidades Especiais". Métodos: A amostra foi composta por 581 prontuários de pacientes com necessidades especiais de 0 a 33 anos de idade. Foram coletadas informações sobre as prevalências de cárie nas dentições decídua e permanente, gengivite, xerostomia, bruxismo, refluxo gastroesofágico, sexo, uso de medicação de ação central, uso de chupeta, sucção digital, alimentação e higiene bucal. Os dados foram analisados por meio da estatística descritiva e teste do qui-quadrado para verificação de associação entre diagnóstico e sexo. Resultados: 51,93% dos pacientes eram meninos, 71,42% possuíam paralisia cerebral, 12,36% tinham refluxo gastroesofágico, 49,30% usavam medicação anticonvulsivante. O diagnóstico de paralisia cerebral quadriespástica esteve associado ao sexo masculino. Dentre as alterações bucais, 4,86% dos casos apresentaram xerostomia. O uso da chupeta foi encontrado em 26,93% dos indivíduos e 18,05% chupavam o dedo. Alterações gengivais foram detectadas em 15,61% das fichas. Em relação à alimentação, 56,97% dos indivíduos consumiam açúcar acima do aceitável, e com relação à higiene bucal, 14,48% foram classificados como ruim e 17,57% moderada. Em 20,57% dos prontuários havia registro de dentes decíduos cariados e em 4,29% de dentes obturados. Do total de pacientes que possuíam dentes permanentes, 13,17% tinha dentes cariados e 7,75% possuía dentes obturados. A prevalência de cárie dentária é moderada com pequena proporção de dentes restaurados. A alimentação é rica em sacarose para quase 60% destes pacientes. Conclusão: os hábitos parafuncionais apresentam um percentual preocupante de prevalência. Por isso, estes pacientes possuem um perfil de doenças bucais com gravidade moderada e que devem ter um acompanhamento odontológico sistemático para que a prevalência de doenças bucais não aumente com o passar dos anos.(AU)

Aim: The present study aimed to describe the profile of the patients who received dental care at a philanthropic institution, within the project "Dental Care for Patients with Special Needs". Methods: This study was carried out by evaluating 581 records of patients with special needs from 0 to 33 years of age. Data were collected on the prevalence of caries in deciduous and permanent dentitions, gingivitis, xerostomia, bruxism, gastroesophageal reflux, sex, use of central action medication, pacifier use, digital suction, feeding, and oral hygiene. Data were analyzed using descriptive statistics and the chi-square test to verify an association between diagnosis and sex. Results: The results showed that 51.93% were boys, 71.42% had cerebral palsy, 12.36% had gastroesophageal reflux, and 49.30% used anticonvulsant medication. The diagnosis of quadrispastic cerebral palsy was associated with males. Xerostomia was observed in 4.86% of the cases. The use of pacifiers was present in 26.93% of the individuals, while 18.05% of the patients used to suck their finger. Gingival changes were detected in 15.61% of the records. In relation to food, 56.97% of the individuals consumed sugar above the acceptable amount, and when oral hygiene was considered, 14.48% were classified as poor and 17.57% as moderate. This study also identified 20.57% of decayed and 4.29% of filled deciduos teeth. Among the patients who had permanent teeth, 13.17% had decayed teeth, while 7.75% had filled teeth. It could therefore be concluded that the prevalence of dental caries is moderate with a small proportion of treated teeth. Diet is rich in sucrose for almost 60% of these patients. Conclusion: The parafunctional habits present a worrisome percentage of prevalence. Therefore, these patients have a profile of oral diseases with moderate severity and should undergo systematic dental follow-up so that the prevalence of oral diseases does not increase over the years.(AU)

Risk factors for dental caries in children with developmental disabilities.

The aim of the present study was to investigate risk factors for dental caries in children with developmental disabilities who were treated at a clinical reference service for patients with special needs in Belo Horizonte, MG, Brazil. This is a retrospective cohort study that evaluated 401 dental charts of individuals without dental caries or restorations in their first dental appointment. The dependent variable was the time of occurrence of new dental caries or restorations and was measured in months. Gender, age, International Code of Diseases (ICD), mother´s education, sugar consumption, use of fluoride toothpaste, oral hygiene, mouth breathing, reports of xerostomia, gingival status, use of psychotropic or asthma drugs, and history of asthma were covariates. The Cox proportional hazards regression model was used to estimate the raw and adjusted hazard ratios and their respective 95% confidence intervals. The average time that individuals remained free of dental caries/restoration was equal to 107.46 months (95%CI 95.41 to 119.51), with a median of caries-free children up to 94 months. For each point increase in the scale of sucrose consumption, the increase in caries risk was 1.07 (95%CI 1.01 to 1.15). Sucrose consumption was the only risk factor for dental caries found in this group of individuals with developmental disabilities.

Factors associated with mouth breathing in children with -developmental -disabilities.

OBJECTIVE: To investigate the prevalence and factors associated with mouth breathing among patients with developmental disabilities of a dental service. METHODS: We analyzed 408 dental records. Mouth breathing was reported by the patients' parents and from direct observation. Other variables were as -follows: history of asthma, bronchitis, palate shape, pacifier use, thumb -sucking, nail biting, use of medications, gastroesophageal reflux, bruxism, gender, age, and diagnosis of the patient. Statistical analysis included descriptive analysis with ratio calculation and multiple logistic regression. Variables with p < 0.25 were included in the model to estimate the adjusted OR (95% CI), calculated by the forward stepwise method. Variables with p ​​< 0.05 were kept in the model. RESULTS: Being male (p = 0.016) and use of centrally acting drugs (p = 0.001) were the variables that remained in the model. CONCLUSION: Among patients with -developmental disabilities, boys and psychotropic drug users had a greater chance of being mouth breathers.

Factors Associated with Gingivitis in Children with Developmental Disabilities

Objective: To investigate factors associated with gingivitis in children aged one to 13 years with developmental disabilities. Material and Methods: A total of 408 dental records were used to recover the data. Gingivitis was measured based on the Modified Gingival Index. Other variables were also analysed: gender, age, International Classification of Diseases (ICD) code, mouth breathing, history of gastroesophageal reflux, use of psychotropic drugs, reports of dry mouth, history of asthma, use of medications to treat asthma, oral hygiene, dental caries, and filled or missing teeth in deciduous or permanent dentition. For the purposes of this analysis, the individuals were categorized as with and without gingivitis. Variables with a p-value < 0.25 in the bivariate analysis were incorporated into the logistic regression models (ICD, reflux, oral hygiene, primary tooth decay or filling, mouth breathing, dry mouth and use of psychotropic drugs). Results: We found a 14.67% prevalence of gingivitis. Individuals with mouth breathing had a 2.574-fold (95% CI: (1.113-5.950) greater chance of exhibiting gingivitis. Individuals with moderate oral hygiene had a 2.763-fold (95% CI: 1.066 to 7.160) greater chance of exhibiting gingivitis, and individuals with poor oral hygiene had a 15.029-fold (95% CI: 3.705-60.965) greater chance of exhibiting gingivitis than those with good oral hygiene. Conclusion: Moderate or poor oral hygiene and mouth breathing are factors associated with gingivitis in a group of patients with developmental disabilities at a dental service in Belo Horizonte.

Oral hygiene protocols in intensive care units in a large Brazilian city.

This study investigated oral hygiene protocols for patients in intensive care units (ICUs) in 25 of 30 hospitals in Belo Horizonte, Brazil, using a questionnaire. Although all hospital representatives said there was a protocol for the maintenance of patients' oral hygiene, it was observed that there was no standardization. Only 2 hospitals had dentists on the ICU staff. Cetylpyridinium chloride was the most frequently used antiseptic, even in patients under mechanical ventilation.

Factors associated with bruxism in children with developmental disabilities.

The aim of the present study was to investigate factors associated with bruxism in children aged from 1 to 13 years with developmental disabilities. A total of 389 dental records were examined. The bruxism analyzed was determined based on parental reports. The following variables were also analyzed: gender, age, International Code of Diseases (ICD), mouth breathing, history of gastroesophageal reflux, use of psychotropic drugs, gingival status, reports of xerostomia, hyperkinesis, pacifier use, thumb sucking and involuntary movements. For the purposes of analysis, the individuals were categorized as being with and without bruxism. Variables with a p-value < 0.25 in the bivariate analysis were incorporated into the logistic regression models. Females had a 0.44-fold (95%CI: 0.25 to 0.78) greater chance of exhibiting bruxism than males. Individuals with gastroesophageal reflux had a 2.28-fold (95%CI: 1.03 to 5.02) greater chance of exhibiting bruxism. Individuals with reported involuntary movements had a 2.24-fold (95%CI: 1.19 to 4.24) greater chance of exhibiting bruxism than those without such movements. Exhibiting involuntary movements, the male gender and gastroesophageal reflux are factors associated with bruxism in children with developmental disabilities.

Critérios diagnósticos: existência de lombalgia e/ou claudicação neurogénica e/ou radiculopatia, associados a um diâmetro anteroposterior do canal menor que 10mm e grupo II com 40 pacientes observados em consulta externa por lombalgia sem clínica de CLE. Foi feita a medicação do diâmetro do canal e verificada a presença do sinal de sedimentação entre D12 a S1. RESULTADOS: O sinal da sedimentação foi positivo em 31 dos 34 pacientes do grupo I (91,2%), em dois destes 31 pacientes apenas abaixo da estenose. Este sinal não foi encontrado em nenhum paciente do segundo grupo. Verifica-se uma correlação estatisticamente significativa entre as variáveis "diâmetro do canal" e a "presença do sinal da sedimentação" (p<0.01) no grupo de pacientes com canal lombar estreito. CONCLUSÕES: O diagnóstico de CLE nem sempre é fácil atendendo à frequente dissonância entre os achados clínicos e imagiológicos. O sinal de sedimentação é positivo em pacientes com CLE entre os níveis L1 e L5, podendo ser um sinal válido para complementar o diagnóstico de CLE.

OBJECTIVE: To verify the presence of the sedimentation sign in patients with lumbar spinal stenosis (LSS) in comparison to those without LSS. METHODS: Retrospective, cross-sectional and descriptive study. Review of the imaging processes of patients with LSS operated between January 1, 2008 and December 31, 2009, comparing with patients without LSS observed in outpatient consultations. Patients were divided into two groups: group I had 34 patients with a diagnosis of LSS. Diagnostic criteria: existence of low back pain and/or neurogenic claudication and/or radiculopathy, associated with an anteroposterior canal diameter of less than 10 mm. Group II had 40 patients observed in outpatient consultations for low back pain without clinical LSS. The canal diameter was measured and the presence of the sedimentation sign between D12 and S1 was verified. RESULTS: A positive sedimentation sign was identified in 31 of the 34 patients in group I (91.2%); only below the stenosis in two of these 31 patients. The sign was not observed in the patients in group II. A statistically significant correlation was observed between the variables "canal diameter" and "presence of sedimentation sign" (p < 0.01) in the group of patients with lumbar spinal stenosis. CONCLUSION: The diagnosis of LSS is not always easy due to the frequent dissonance between the clinical and imaging findings. The sedimentation sign is positive in patients with LSS between L1 and L5 and can be a valid sign to complement the diagnosis of LSS.

OBJETIVO: Verificar la presencia de la señal de sedimentación en los pacientes con Canal Lumbar Estrecho (CLE), comparándolos con los pacientes sin CLE. MÉTODOS: Realizado un estudio retrospectivo, transversal y descriptivo. Realizada la revisión de los procesos de imagen de los pacientes con CLE operados entre el 1ro de enero de 2008 y el 31 de diciembre de 2009, en comparación con los pacientes sin CLE observados en las consultas externas. Creamos dos grupos de pacientes: grupo I, 34 pacientes con diagnóstico de CLE. Criterios de diagnósticos: existencia de lumbago y/o claudicación neurogénica y/o radiculopatía, asociados a un diámetro del canal menor de 10 mm. Grupo II, 40 pacientes observados en consultas externas por lumbago sin clínica de CLE. Se realizó la medicación del diámetro del canal y fue verificada la presencia de la señal de sedimentación entre D12 y S1. RESULTADOS: La señal de la sedimentación fue positiva en 31 de los 34 pacientes del grupo I (91,2 %), en dos de estos 31 pacientes solamente por debajo de la estenosis. Esta señal no se encontró en ningún paciente del segundo grupo. Se verificó una correlación, estadísticamente significativa, entre las variables "diámetro del canal" y la "presencia de la señal de la sedimentación" (p<0,01) en el grupo de pacientes con canal lumbar estrecho. CONCLUSIONES: El diagnóstico de CLE no siempre es fácil atendiendo a la frecuente discrepancia entre los hallazgos clínicos y de imagen. La señal de sedimentación es positiva en pacientes con CLE entre los niveles L1 y L5, pudiendo ser una señal válida para complementar el diagnóstico de CLE.

Factors associated with dental caries in the primary dentition of children with cerebral palsy

The aim of this study was to investigate factors associated with caries experience in the primary dentition of one- to five-year-old children with cerebral palsy. A total of 266 dental records were examined, and caries experience was measured by dmft. The following variables were also analyzed: gender, oral hygiene, history of gastroesophageal reflux, use of medications for gastroesophageal reflux, gingival status, sugar intake and reports of polyuria, excessive thirst and xerostomia. For analysis purposes, the individuals were categorized as those with and without caries experience and subcategorized into the following age groups: one year; two to three years; and four to five years. After bivariate analysis, variables with a p-value < 0.25 were selected for incorporation into the Poisson regression models. Considering the limitations of the protocol, the level of oral hygiene perceived on the first appointment was the only factor associated with caries experience among two-to-fiveyear-old children with cerebral palsy.
