“…However, calculating surface density by the point-counting method is time-consuming, as the analysis of the structure of interest requires the full observer's attention to avoid overcounting or missing points that touch the studied structure. To overcome these issues, the color-based segmentation method is increasingly being used in several laboratories (as used in this study or with some variations) [ 13 , 14 , 19 ]. This method is based on the principle of differential color staining of structures, after which the percentage of pixels of one color can be measured in the field using different image editing software.…”

The use of morphometrical tools in biomedical research permits the accurate comparison of specimens subjected to different conditions, and the surface density of structures is commonly used for this purpose. The traditional point-counting method is reliable but time-consuming, with computer-aided methods being proposed as an alternative. The aim of this study was to compare the surface density data of penile corpus cavernosum trabecular smooth muscle in different groups of rats, measured by two observers using the point-counting or color-based segmentation method. Ten normotensive and 10 hypertensive male rats were used in this study. Rat penises were processed to obtain smooth muscle immunostained histological slices and photomicrographs captured for analysis. The smooth muscle surface density was measured in both groups by two different observers by the point-counting method and by the color-based segmentation method. Hypertensive rats showed an increase in smooth muscle surface density by the two methods, and no difference was found between the results of the two observers. However, surface density values were higher by the point-counting method. The use of either method did not influence the final interpretation of the results, and both proved to have adequate reproducibility. However, as differences were found between the two methods, results obtained by either method should not be compared.

Background:Trigger finger (TF) is a common referral to a hand surgeon, with people with diabetess being the most at-risk population. Abnormal thickening, scarring, and inflammation occur at the A1 pulley and flexor tendon, and histological changes correlate well with the clinical severity of TF. Corticosteroid injections decrease the thickness of the A1 pulley and are considered a first-line treatment. However, corticosteroids are only moderately effective, especially for people with diabetes. Patients may elect for surgery if nonoperative treatments prove ineffective; some may choose immediate surgical release instead. To release the A1 pulley, patients have the option of an open or percutaneous approach. The open approach has a greater risk of infection and scar tissue formation in the short run but an overall superior long-term outcome compared with the percutaneous approach.Methods:We critically reviewed the efficacy and cost-effectiveness of the treatment methods for TF through a comprehensive search of the PubMed Database from 2003 to 2019.Results:To reduce costs, while still delivering the best possible care, it is critical to consider the likelihood of success for each treatment method in each subpopulation. Furthermore, some patients may need to return to work promptly, which ultimately may influence their desired treatment method.Conclusions:Currently, there is no universal treatment algorithm for TF. From a purely financial standpoint, women without diabetes presenting with a single triggering thumb should attempt 2 corticosteroid trials before percutaneous release. It is the most cost-effective for all other subpopulations to elect for immediate percutaneous release.

“…Trigger finger (stenosing flexor tenosynovitis) was a term first proposed by Notta in 1850. 1 This condition is a common cause of hand pain, which can result in limited finger, edema, discomfort, and disability, with a "triggering" sensation. 2 Trigger finger is characterized by blocked sliding movements of the flexor tendon during finger flexion and extension.…”

Resumo Objetivo Avaliar o planejamento terapêutico para o dedo em gatilho por ortopedistas brasileiros. Métodos Estudo transversal, cuja população foi composta por participantes do Congresso Brasileiro de Ortopedia e Traumatologia 2018 (CBOT-2018). Foi aplicado um questionário sobre a conduta adotada no diagnóstico e tratamento do dedo em gatilho. Resultados Foram analisados 243 participantes com média de idade de 37.46 anos, na maioria homens (88%), tempo de experiência de pelo menos 1 ano (55,6%), e da região Sudeste (68.3%). A análise dos questionários evidenciou que há consenso nos seguintes quesitos: diagnóstico somente com exame físico (73,3%), classificação de Quinnell modificada por Green (58,4%), tratamento inicial não cirúrgico (91,4%), infiltração de corticoide com anestésico (61,7%) tempo de tratamento não cirúrgico de 1 a 3 meses (52,3%), tratamento cirúrgico pela via aberta (84,4%), principalmente via aberta transversa (51%), recidiva do engatilhamento como principal complicação não cirúrgica (58%), e o sucesso da cirurgia aberta em > 90% (63%), sendo a sua principal complicação as complicações cicatriciais (54%). Sem consenso nas demais variáveis. De acordo com a experiência, foram observadas diferenças referentes ao tempo de tratamento (p = 0.013) e a taxa de complicação da cirurgia aberta (p = 0.010). Conclusões O ortopedista brasileiro tem preferência pelo diagnóstico do dedo em gatilho apenas com exame físico, classifica segundo Quinnell modificado por Green, tratamento inicial não cirúrgico, infiltrações com corticoide e anestésico local, tempo de tratamento não cirúrgico de 1 a 3 meses, tratamento cirúrgico por via aberta transversa, principal complicação não cirúrgica a recidiva do engatilhamento, e considera o sucesso da cirurgia aberta em > 90% dos casos, tendo como principal complicação as complicações cicatriciais.
