Resumo Objetivos: analisar a influência da qualidade do ambiente no desenvolvimento motor de crianças na faixa etária entre seis e 15 meses que frequentam centros de educação infantil. Métodos estudo de delineamento transversal e analítico sobre o desenvolvimento motor de crianças entre seis e 15 meses de idade, de ambos os sexos, matriculadas em turmas de berçário (0-12 meses) e maternal I (12-24 meses), com utilização das escalas validadas Affordances in the Home Environment for Motor Development-Infant Scale e Alberta Infant Motor Scale. Resultados: a amostra de 104 crianças e 30 centros de educação infantil apresentou idade média de 9,15 meses, 88% permanecia em período integral e 12% meio período (manhã ou tarde), um centro foi classificado como Affordance Fraca, 26 Suficiente e três Adequada. Das crianças participantes, 40% apresentaram desenvolvimento motor normal. Os maiores níveis de Affordance indicam melhor desenvolvimento motor e níveis menores de Affordance sinalizam suspeita de atraso motor. Conclusão: o ambiente de centros de educação infantil em que a criança está inserida exerce influência no desempenho motor, principalmente ligado às atividades diárias e uso de brinquedos. Quanto menor o nível de Affordance mais possibilidades de suspeita de atraso motor infantil.

Abstract Objectives: to analyze the influence of the quality in the environment on children’s motor development between six to 15 months old attending early childhood education centers. Methods: a cross-sectional and analytical study addressing children’s motor development between six to 15 months old, both sexes, enrolled in nursery (0-12 months) and preschoolers (12-24 months). The Affordances in the Home Environment for Motor Development-Infant Scale and Alberta Infant Motor Scale were used in the Brazilian versions Results: the sample was comprised of 104 children and 30 early childhood education centers: presenting a mean age of 9.15 months, 88% attended full-time and 12% part-time schooling (mornings or afternoons). One center was classified with a low Affordances, 26 were considered Sufficient, and three were Adequate. Of the participating children, 40% presented typical motor development. The higher levels of Affordances suggest better motor development, and lower levels of suspected delayed motor development. Conclusion: the environments of early childhood education centers influence children’s motor performance, especially daily activities and the use of toys. The lower the Affordances level, more likely children are suspected of delayed motor development.

It was our objective to analyse the effects of resistance exercise (climbing steps), which was started in the acute phase, on the histomorphometry and the expression of aquaporin 1 (AQP1) in the soleus muscle after sciatic nerve injury in Wistar rats. Twenty-four adult rats were randomly divided into the following four groups, containing six animals each: control (G1); exercise (G2); injury (G3); and exercise with injury (G4). Three days after the compression of the sciatic nerve, the animals in G2 and G4 were submitted to resistance exercise for 21 non-consecutives days. The exercise was conducted in two series of 10 consecutive ascents of the ladder, with an additional weight of 100g and with an interval of 60 seconds between sets for rest. After this period, the animals were sacrificed, and the soleus muscle was processed. The number of blood capillaries in G3 was 65.7% and 76.86% higher when compared with the G2 and G4, respectively. The morphological analysis revealed muscle damage in G3, hypertrophy in G2 and significant improvement in the muscle in G4. The AQP1 was immunolocalized in the endothelium of blood capillaries present in the muscle fibres, with different expressions in the groups. Resistance exercise initiated in the acute phase was an effective therapeutic modality in the recovery of morphological aspects in the soleus muscle after denervation.

ABSTRACT Objetivo: analisar o perfil dos pacientes com gangrena de Fournier tratados em um hospital público terciário do oeste do Paraná. Métodos: estudo transversal, retrospectivo e descritivo de pacientes portadores de gangrena de Fournier atendidos no período de janeiro de 2012 a novembro de 2016. Resultados: foram tratados 40 pacientes com gangrena de Fournier no período: 29 (72,5%) homens e 11 (27,5%) mulheres. A média de idade foi de 51,7±16,3 anos. A média de tempo de evolução da doença, do sintoma inicial até a internação, foi de 10,5±1,2 dias. Todos os pacientes apresentaram algum sinal clínico como dor, abaulamento, eritema, entre outros, e 38 (95%) tinham comorbidades associadas, sendo as mais comuns diabetes mellitus tipo 2 e hipertensão arterial sistêmica. A maioria (30 pacientes -75%) apresentava como etiologia provável abscesso perianal. Todos os pacientes foram submetidos à antibioticoterapia e tratamento cirúrgico com média de 1,8±1,1 cirurgias por paciente. Nove (22,5%) pacientes morreram. Houve forte correlação entre a presença de sepse na admissão e mortalidade. Conclusão: pacientes portadores de gangrena de Fournier, nesta casuística, apresentavam longo tempo de doença e elevada prevalência de comorbidades com alto índice de mortalidade.

ABSTRACT Objective: to analyze the profile of patients with Fournier’s gangrene treated in a public tertiary hospital in western Paraná State. Methods: we conducted a cross-sectional, retrospective and descriptive study of patients with Fournier’s gangrene treated between January 2012 and November 2016. Results: there were 40 patients with Fournier’s gangrene treated in the period, 29 (72.5%) men and 11 (27.5%) women. The mean age was 51.7±16.3 years. The mean time of disease progression, from the initial symptom to hospitalization, was 10.5±1.2 days. All patients had clinical signs such as pain, bulging, erythema, among others, and 38 (95%) had associated comorbidities, the most common being type 2 diabetes mellitus and systemic arterial hypertension. The majority (30 patients - 75%) had perianal abscess as the probable etiology. All patients were submitted to antibiotic therapy and surgical treatment, with a mean of 1.8±1.1 surgeries per patient. Nine (22.5%) patients died. There was a strong correlation between the presence of sepsis on admission and mortality. Conclusion: Fournier’s gangrene patients in this series had a long disease duration and a high prevalence of comorbidities, with a high mortality rate.

RESUMO Objetivo Avaliar a ação da vanilina (Vanilla planifolia) sobre a morfologia dos músculos tibial anterior e sóleo após lesão nervosa periférica. Métodos Ratos Wistar foram divididos em quatro grupos, com sete animais cada, sendo Grupo Controle, Grupo Vanilina, Grupo Lesão e Grupo Lesão + Vanilina. Os animais dos Grupos Lesão e Grupo Lesão + Vanilina foram submetidos à lesão nervosa por meio da compressão do nervo isquiático, e os Grupos Vanilina e Grupo Lesão + Vanilina foram tratados diariamente com doses orais de vanilina (150mg/kg) do 3o ao 21o dia após a indução da lesão nervosa. Ao término do experimento, os músculos tibial anterior e sóleo foram dissecados e seguiram o processamento de rotina em microscopia de luz, para posterior análise morfológica. Resultados A compressão nervosa promoveu alterações morfológicas características de denervação, sendo que o tratamento com vanilina foi responsável por respostas distintas nos músculos estudados. Para o tibial anterior, houve aumento do número de células satélites, núcleos centrais e atrofia das fibras, bem como desorganização fascicular. Já no sóleo, houve apenas aumento da vascularização, sem exacerbação das alterações morfológicas nas fibras. Conclusão O tratamento com vanilina promoveu o aumento da vascularização intramuscular para os músculos estudados, com potencial pró-inflamatório para o tibial anterior, o que não ocorreu no músculo sóleo.

ABSTRACT Objective To evaluate the action of vanillin (Vanilla planifolia) on the morphology of tibialis anterior and soleus muscles after peripheral nerve injury. Methods Wistar rats were divided into four groups, with seven animals each: Control Group, Vanillin Group, Injury Group, and Injury + Vanillin Group. The Injury Group and the Injury + Vanillin Group animals were submitted to nerve injury by compression of the sciatic nerve; the Vanillin Group and Injury + Vanillin Group, were treated daily with oral doses of vanillin (150mg/kg) from the 3rd to the 21st day after induction of nerve injury. At the end of the experiment, the tibialis anterior and soleus muscles were dissected and processed for light microscopy and submitted to morphological analysis. Results The nerve compression promoted morphological changes, typical of denervation, and the treatment with vanillin was responsible for different responses in the studied muscles. For the tibialis anterior, there was an increase in the number of satellite cells, central nuclei and fiber atrophy, as well as fascicular disorganization. In the soleus, only increased vascularization was observed, with no exacerbation of the morphological alterations in the fibers. Conclusion The treatment with vanillin promoted increase in intramuscular vascularization for the muscles studied, with pro-inflammatory potential for tibialis anterior, but not for soleus muscle.

Abstract Aim to determine the effects of sciatic compression and treatment with resistance exercise on the morphology of the ankle joint of Wistar rats. Methods 32 male rats, aged 10 ± 1 week, weighing 376±22 grams were divided into the following four groups (n=8/group): CG (control), LG (lesion), EG (exercise) and LEG (lesion and exercise). Three days after sciatic compression, the animals in the EG and LEG were submitted to resistance exercise by climbing stairs (five days/week) for three weeks and a load of 100 grams was added. The exercise was carried out in two sets of ten consecutive ascents of the steps. The ankle joint tissues were analyzed for their morphometry and morphology using light microscopy. Results Regarding the number of chondrocytes, the LG and EG had more cells in the anterior articular cartilage in the tibia (62 and 43%) and in the talus (57 and 45%) when compared to the CG. In the LEG there was a 25% and 26% reduction of chondrocytes in the anterior cartilage in the tibia and talus when compared to the LG. Changes were observed in the tibia and talus in the LG, with the presence of flocculation, invagination of the subchondral bone, discontinuity of tidemark and pannus covering the subchondral bone in the talus, as well as changes in the synovial membrane. These alterations were minimized in the articular cartilage and synovial membrane in the LEG. Conclusions exercise restores the tissue morphology of ankle joint in Wistar rats after sciatic compression.
