Toilet training methods in children with normal neuropsychomotor development: A systematic review.

BACKGROUND: Toilet training (TT) is an important milestone in child development. The purpose of this review is to summarize the different TT methods found in the literature and determine their effectiveness for the TT process. DATA SOURCES: Articles about toilet training were collected from databases, including PubMed and Scopus. The Preferred Reporting Items for Systematic Reviews (PRISMA) statement was used to guide the systematic review. RESULTS: Two main classifications were used: a child-oriented approach and a structured behavioral approach. Most children were trained by the structured behavioral approach, with early onset, but at the age of completion of TT, similar to those who used a child-oriented approach. Success rates, in the few studies that reported, were better with the child-oriented approach. The lowest reported success rate was the daytime humidity alarm approach. There is no consensus on the best method to be used, as it involves a wide variety of parents' preferences and expectations and cultural differences, with studies showing great heterogeneity and methodological flaws that make meta-analysis unfeasible. CONCLUSIONS: The approaches have not been directly compared, so it isn't possible to make definitive claims about one method's superiority over the other.

Evaluation of platelet-rich plasma gel as an angiogenesis-inducing agent in canine advancement skin flaps / Avaliação do gel de plasma rico em plaquetas como agente indutor da angiogênese em flapes cutâneos de avanço em cães

This work aimed to evaluate the effect of platelet-rich plasma (PRP) on advancement skin flaps in dogs regarding improvement of vascularization, with focus on increasing its viable area, since there are reports that it is a potential angiogenesis stimulator. The experimental group was composed of eight adult bitches, in which two advancement skin flaps were made in the ventral abdominal region. No product was applied in the control flap (CF), while PRP was used in the contralateral flap, called treated flap (TF). The areas were clinically evaluated every two days until the 7th postoperative day regarding skin color and presence of necrosis. At 10 days, both flaps were removed and submitted to histological examination and blood vessel morphometry. The vessels counted in each group were statistically analyzed by the F-test at 1% probability. Results showed no significant difference in macroscopic changes in the wound, or CF and TF vascularization, thus suggesting that PRP gel did not improve advancement skin flap angiogenesis in bitches under the experimental conditions in which this research was developed.(AU)

Objetivou-se com o presente artigo avaliar a ação angiogênica do gel de plasma rico em plaquetas (PRP) em flapes cutâneos de avanço em animais da espécie canina, visando aumentar a viabilidade da pele após o procedimento, uma vez que existem relatos de que o produto é um potente estimulador da angiogênese. O grupo experimental foi composto por oito cadelas adultas, onde foram confeccionados dois flapes de avanço (de padrão subdérmico) na região abdominal ventral. Em um dos flapes, considerado controle (FC) não foi aplicado nenhum produto, enquanto que no flape contralateral, denominado tratado (FT), foi usado o gel de PRP. As áreas foram macroscopicamente avaliadas a cada dois dias até o 7º dia de pós-operatório em relação à coloração da pele e presença de área de necrose, e com 10 dias ambos os flapes foram coletados por biópsia e submetidos ao exame histológico e morfometria dos vasos sanguíneos. Os vasos contados em cada grupo foram estatisticamente analisados pelo teste de F ao nível de 1% de probabilidades. Os resultados demonstraram que não houve diferença significativa nas alterações macroscópicas das feridas e na morfometria vascular dos FC e FT, sugerindo dessa maneira que dentro das condições experimentais nas quais a pesquisa foi executada, que o gel de PRP não incrementou a angiogênese de flapes de avanço em cadelas.(AU)

Lesão de Morel-Lavallée: relato de caso / Morel LavalléeLesion: case report

A lesão de Morel-Lavallée, descrita inicialmente no século XIX pelo cirurgião francês Victor Auguste François Morel-Lavallée, constitui lesão de partes moles, sobretudo nas áreas que revestem as protuberâncias ósseas. Sua fisiopatologia consiste no deslocamento da pele e do tecido celular subcutâneo sobre a fáscia muscular, provocado por forças tangenciais súbitas e intensas, secundárias a traumatismos. No espaço criado pela avulsão dos tecidos, acumulam-se sangue, linfa e debris gordurosos. O diagnóstico é baseado na história clínica, no exame físico e nos exames de imagem. O tratamento geralmente é conservador e o prognóstico é bom, nas lesões menores. Em casos de lesões extensas podem ocorrer graves complicações. O diagnóstico diferencial inclui bursite, hematoma, abscesso, tumores benignos e neoplasias malignas. O presente relato visa alertar o pediatra sobre a possibilidade diagnóstica de lesão de Morel-Lavallée, garantindo-se sua abordagem precoce e adequada, especialmente quando se considera a prática de esportes cada vez mais comum entre crianças e adolescentes, além do risco da sua ocorrência por traumas associados às atividades lúdicas próprias da faixa etária pediátrica.(AU)

The injury of Morel-Lavallée, first described in the nineteenth century by the French surgeon Victor Auguste François Morel-Lavallée, is a soft tissue injury, particularly in the linimg areas of the bony prominences. The patophysiology consists in the displacement of the skin and the fascia subcutaneous tissue caused by sudden and intense shear forces, secondary to trauma. In the space created by tissue avulsions acumulates blood, lymph and fatty debris. Diagnosis is based on clinical history, physical examination and imaging studies. Treatment is usually conservative and the prognosis is good, in the minor injuries. In cases of extensive lesions the result can be serious complications. The differential diagnosis includes bursitis, hematoma, abscess, benign and malignant neoplasms. This report aims to alert the pediatrician about the diagnostic possibility of Morel-Lavallée lesion nsuring their early and appropriate approach, especially when we consider the practice of sports, increasingly common among children and adolescents, and the risk of their occurrence of traumas associated with own play activities of pediatric patients.(AU)
