RESUMEN
Objective To evaluate the clinical and radiographic characteristics and function of erosive hand osteoarthritis (EOA) patients. Methods Data were obtained from 19 patients with EOA, including their social conditions, clinical conditions, radiographic scores and hand function evaluation. The number of hand osteoarthritis (HOA) patients was 312. The control group consisted of non-EOA patients with hand osteoarthritis with a ratio of 4:1 to EOA patients. A non-parameter test analysis was performed. All data were analyzed by SPSS 23.0 statistical analysis, t test, χ2 test, Fisher exact probility and Spearman's correlations analysis were used for statistical analysis. Results Totally data of 19 patients were collected. Eighteen were female. Onset age was (56±8). Average duration was 56 (12~120) months. FIHOA scores of all the EOA patients were at least 5. All the erosions of 39 joints were characteristically central and erosive changes in 7 joints (18%) showed up as gull-wing. Among 39 erosive joints, including 12 (31%) E and 27 (69%) R, 34 (87%) distal interphalangeal joints were involved. Data analysis found out that EOA patients had longer disease duration (Z=2.610, P=0.009), more severe K-L level (44 ±11 vs 26 ±7, t=7.134, P<0.01), higher AUSCAN total score (28±6 vs 21±7, t=3.781, P<0.01) and higher AUSCAN function score (18±6 vs 12±6, t=4.042, P<0.01). The differences of ESR and CRP were not significant between EOA and non-EOA patients. Conclusion Erosions seen in EOA patients are centrally located gull-wing in the DIP joints. EOA patients have longer duration, more severe radiographic damage and worse joint function.
RESUMEN
Purpose: The present work consists of a comparative study of two indexes of skeletal maturation: the carpal index (SMI) and the vertebral index (CVMI) and verification of the reliability of the vertebral index in the determination of the stages of the skeletal maturation. Methods: Radiographies from the dental records of treated patients from Universidade do Sul de Santa Catarina (UNISUL) were used. The sample was composed of 158 radiographies comprising seventy-nine carpal and seventy-nine lateral cephalometric radiographies of patients of both genders between six and eighteen of age. The carpal radiographies were analyzed using Martins' method and the lateral cephalometric, according to Baccetti, Franchi and McNamara Jr. Results: The Spearman's correlation test results showed a significant correlation coefficient of 0.616 between SMI and CVMI and the Pearson's test, of 0.698 for both genders (P<0.0001). The correlation between the indexes and the chronological age was 0.775 for SMI using Spearman's test, and 0.974 using Pearson's correlation test. For the CVMI, Spearman's correlation was 0.563 and Pearson's was 0.717, showing that there is a statistically significant correlation. Conclusion: The SMI is the safest and most trustworthy method to evaluate the skeletal maturation, although the CVMI can be used as a substitute method when there is conversance with the morphologic alterations of the vertebrae and when the carpal radiography is not available in the patient's orthodontic records.
Objetivo: Comparar o índice de maturação esquelética carpal (IMC) e o índice vertebral (IMV) e verificar a confiabilidade do IMV na determinação desta maturação. Metodologia: Utilizou-se radiografias dos prontuários da disciplina de Ortodontia da UNISUL. A amostra foi composta por 158 radiografias, sendo 79 carpais e 79 cefalométricas em norma lateral, de pacientes com idades variando entre 6 e 18 anos, de ambos os sexos. Para a determinação do IMC utilizou-se o método de Martins e para o IMV, o de Baccetti, Franchi e McNamara Jr. Resultados: Os testes de correlação de Spearman e Pearson mostraram um índice entre IMC e IMV de 0,616 e 0,698, respectivamente, correlação estatisticamente significante para ambos os sexos (P<0,0001). A correlação de Spearman e de Pearson entre o IMC e a idade cronológica foi de 0,775 e 0,974, respectivamente. Já entre o IMV e a idade cronológica foi de 0,563 e 0,717, respectivamente, uma correlação também estatisticamente significante. Conclusão: O IMC é o método mais seguro e confiável de avaliação da maturação esquelética, porém o IMV pode ser usado como método substituto quando houver familiaridade com as alterações morfológicas das vértebras e quando a radiografia carpal não estiver disponível na documentação ortodôntica.
