Functional recovery time after facial fractures: characteristics and associated factors in a sample of patients from southern Brazil.

Understanding the cause, severity, and elapsed time for the restoration of the functions of maxillofacial injuries can contribute to the establishment of clinical priorities aiming at effective treatment and further prevention of facial trauma. The objective of this study was to understand the factors associated with the restoration of mastication, ocular, and nasal functions in the face of trauma victims, estimating their recovery time after surgical treatment. We analyzed 114 medical records of patients treated at the Hospital Montenegro, who attended follow-up consultations for up to 180 days. For analysis of the recovery time, we performed survival analysis, followed by COX analysis. We observed that half of the patients recovered their functions within 20 days. The average time for recovery from trauma in the zygomatic-orbital-malar-nasal complex was 11 days, and in the maxillary-mandibular complex, 21 days (HR: 1.5 [0.99 2.3], p = 0.055). Although functional reestablishment has reached high rates after the surgical approach, it is necessary to analyze the failing cases, as well as the economic impacts and the prevention strategies associated with facial trauma, to improve the service to the population.

The objective of this study was to understand the factors associated with the restoration of mastication, ocular, and nasal functions in the face of trauma victims, estimating their recovery time after surgical treatment.

RESUMO O entendimento da causa, da gravidade e do tempo decorrido para o restabelecimento das funções de lesões maxilofaciais pode contribuir para o estabelecimento de prioridades clínicas objetivando o efetivo tratamento e prevenção dos traumatismos de face. Assim, o objetivo deste estudo foi compreender quais os fatores associados ao restabelecimento das funções mastigatórias, oculares e nasais em vítimas de trauma de face, estimando o tempo para recuperação das funções, após o tratamento cirúrgico. Foram analisados 114 prontuários de pacientes atendidos no Hospital de Montenegro que compareceram às consultas de acompanhamento por até 180 dias. Para a análise do tempo para a recuperação, foi realizada a análise de sobrevida, seguida da análise de COX. Observou-se que metade dos pacientes recuperaram as funções em até 20 dias, sendo que o tempo médio para recuperação dos traumas no complexo zigomático-orbitário-malar-nasal foi de 11 dias e do complexo maxilo - mandibular de 21 dias (HR: 1,5 (0,99 - 2,3) p=0,055). Embora o restabelecimento das funções tenha atingido taxas elevadas após abordagem cirúrgicas, faz-se necessária a análise dos casos de insucessos bem como os impactos econômicos e as estratégias de prevenção associados aos traumas de face a fim de qualificar o serviço prestado à população.

Development and evaluation of multiparticulate biphasic system for the treatment of circadian diseases

Multiparticulate systems have biopharmaceutical advantages when compared to the monolithic systems, once they allow different patterns of drug release and can be used in different treatments. The aim of the present work was to develop a biphasic controlled release delivery system, using propranolol hydrochloride (PROP) that can be used for the treatment of circadian diseases. This system was obtained by the combination of cellulosic polymers hydroxypropyl methylcellulose (HPMC) and ethylcellulose (EC) in a 2² factorial experimental design, which allowed the optimization of the development stage. The pellets produced and used in biphasic formulations were evaluated for physical and chemical characteristics and presented acceptable results. The immediate fraction obtained showed the complete release in 30 min while the others kept the release of the drug for 24 h. This study showed that the combination of beads with different releasing characteristics allowed to obtain different release profiles, which can be modulated according to the pathological needs, especially with regard to circadian diseases that suffer alterations throughout the day.

Preparing silk fibroin nanofibers through electrospinning: further heparin immobilization toward hemocompatibility improvement.

Sodium heparin (HS) was immobilized on the surface of the silk fibroin nanofibers (FS) prepared by electrospinning with the objective of improving the hemocompatibility of the fibers for application as scaffolds in tissue engineering. The nanofiber mats of silk fibroin without (MF-FS) and with (MF-FS/HS) immobilized heparin were characterized through scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR), thermogravimetric analyses (TGA), energy dispersive spectroscopy (EDS), contact angle, chemical analysis, and biological tests. The formation of hydrogen bonds between the silk fibroin and heparin was discussed based on FTIR-ATR spectra. The amount of immobilized heparin was quantified through papain/N-acetyl-l-cysteine digestion followed by dimethylmethylene blue complexation. Furthermore, the samples with immobilized HS showed higher hydrophilic capability compared to samples without HS due to lower contact angles. It was possible to verify that the capillary end-to-collector distance of 8.5 cm and flow rate of 0.35 mL h(-1) used in the electrospinning process at 20 kV are good conditions for obtaining a small average fiber diameter maintaining the amount of immobilized heparin on MF-FS/HS in ca. 4% w/w. Biological analysis showed that no hemolysis is provoked by MF-FS and MF-FS/HS mat fragments and those such mats are not toxic to Vero cells. However, the MF-FS/HS showed higher cell growth and proliferation than MF-FS, indicating an improvement in the hemocompatibility of the material due to heparin immobilization.

Siringoma condróide: relato de caso / Chondroid Syringoma: Case Report

O siringoma condróide é um tumor misto cutâneo, benigno e raro, com prevalência de aproximadamente 0,01% dos tumores de pele. Oitenta por cento dos siringomas condróides são encontrados em idosos, sendo que a proporção é de duas mulheres para cada homem. Frequentemente encontrado na região da cabeça e pescoço principalmente no couro cabeludo, face e nariz. Lesões no tronco e extremidades são extremamente raras. As lesões possuem entre 0,5 e 3 cm e são firmes e aderentes à pele, mas distinguível das demais estruturas. Neste artigo se relata um caso de uma lesão na região do lábio superior... (AU)
