ABSTRACT
OBJECTIVE: To compare the manufacturing, infusion, and total times of handmade balloons for uterine tamponade using the El Hennawy and Alves techniques, given the failure of initial measures and uterotonic therapy to control postpartum hemorrhage. METHODS: An open clinical trial (clinical article) was conducted among 30 physicians, residents, and assistants in an Obstetrics Department. Each participant manufactured and infused one of two different balloons compared in the study, in a randomly predefined sequence. The manufacturing and infusion times were timed by the researchers and their medians were compared using the t test or Mann-Whitney U test. RESULTS: The manufacturing time of the El Hennawy balloon was 72 s lower in relation to the Alves balloon (P < 0.010). Regarding the infusion time, the Alves balloon was filled faster than the El Hennawy balloon (P < 0.010). The total time (manufacturing and infusion) of Alves balloon was also lower than the El Hennawy device (P < 0.010). CONCLUSIONS: Although the El Hennawy balloon was manufactured more quickly, the total time of manufacturing and infusing the Alves balloon was much faster, which makes it the most suitable device to be used in critical situations of postpartum hemorrhage.

ABSTRACT Purpose To evaluate the agreement among instruments of the quantitative evaluation of hard palate. Methods This cross-sectional study was performed with a sample of 30 children aged 6 to 11 from Santa Maria, Southern Brazil. The instruments for palate measurements evaluated were: digital caliper, used directly in the oral cavity and in plaster casts, Korkhaus tridimensional bow, used directly in the oral cavity and in plaster casts, and Dolphin Imaging Software used for measurements in cone-beam computed tomography (CBCT). The agreement among different instruments was evaluated using the Intraclass Correlation Coefficient (ICC). Results The means of all transversal dimensions obtained by cone-beam computed tomography were lower than those of the other instruments - the agreement values in the width between the canines and in the width between the first molars were lower when comparing the cone-beam computed tomography and the other instruments. In the width between the first and second premolars, all comparisons showed acceptable agreement values. Good concordance values were obtained when comparing the palate depth at the second premolar region when using a bow divider inside the oral cavity and in the cast. Conclusion Most instruments presented satisfactory agreement in the measurements related to the transverse plane of the hard palate. However, when the vertical plane was evaluated, only the bow divider applied to both cast and oral cavity presented ideal agreement.
RESUMO Objetivo Avaliar a concordância entre instrumentos de avaliação quantitativa do palato duro. Método Este estudo transversal foi realizado com uma amostra de 30 crianças de 6 a 11 anos de Santa Maria, sul do Brasil. Os instrumentos de medidas do palato avaliados foram: paquímetro digital, utilizado diretamente na cavidade oral e em modelos de gesso, arco tridimensional Korkhaus, usado diretamente na cavidade oral e em modelos de gesso, e Dolphin Imaging Software utilizado para medições em tomografia computadorizada de feixe cônico (CBCT). A concordância entre os diferentes instrumentos foi avaliada por meio do Coeficiente de Correlação Intraclasse (ICC). Resultados As médias de todas as dimensões transversais obtidas pela tomografia computadorizada de feixe cônico foram menores do que as dos outros instrumentos - os valores de concordância na largura entre os caninos e na largura entre os primeiros molares foram baixos na comparação entre a tomografia computadorizada de feixe cônico e os demais instrumentos. Na largura entre o primeiro e o segundo pré-molar, todas as comparações apresentaram valores de concordância aceitáveis. Valores de concordância aceitáveis também foram obtidos ao comparar a profundidade do palato na região do segundo pré-molar com o uso de um divisor de arco dentro da cavidade oral e no gesso. Conclusão A maioria dos instrumentos apresentou concordância satisfatória nas medidas relacionadas ao plano transverso do palato duro. Porém, quando avaliado o plano vertical, apenas o divisor de arco aplicado tanto no gesso quanto na cavidade oral apresentou concordância ideal.
ABSTRACT
Most osteochondral lesions of the first metatarsal head are likely traumatic in etiology. The treatment ranges from microfractures to mosaicplasty. In this case report, we describe a central osteochondral lesion of the first metatarsal head treated with osteochondral graft obtained from the head of the same metatarsal in combination with Moberg osteotomy. After surgical treatment, the patient's American Orthopedic Foot and Ankle Society Forefoot Scale score improved from 58 to 85, and the range of motion also improved. This technique may be an alternative treatment modality for osteochondral lesions of the first metatarsal.Level of Evidence: Level V.
