Effectiveness of three different local routes of dexamethasone administration on postoperative sequelae following mandibular third molar surgery. A prospective randomised single-blind clinical study / Eficácia de três diferentes vias locais de administração de dexametasona em sequelas pós-operatórias após cirurgia de terceiros molares inferiores. Um estudo clínico prospectivo randomizado simples-cego

Objective: The aim of this study was to provide evidence for comparing the effectiveness of three different routes of local administration of Dexamethasone on the postoperative pain, edema and trismus following surgical removal of impacted mandibular third molar. Material and Methods: Forty-five patients underwent surgical removal of impacted lower third molars and were randomly allocated postoperatively into 3 groups: 8 mg of dexamethasone injected into the submucosa of the vestibule near the surgical site (group I), 8 mg of dexamethasone injected into the pterygomandibular space (group II) and 10 mg of dexamethasone powder applied to the extraction site, after bleeding control (group III). Facial swelling and maximal interincisal opening were measured at preoperatively. Pain was measured by the patient response to a visual analogue scale. Pain perception, Facial edema and trismus were evaluated for one week postoperatively. Results: There was no significant difference between the three groups concerning pain after 1, 2, 5, 7 days of follow up. However, group II showed less pain at 3 and 4 days. The difference between edema measurements was not significant in the three groups at 1, 5, 7 days, though in group I and II edema subsided from day 2. As for trismus, group I and III showed statistically significant lower maximum interincisal opening measurement than group II after two days. Conclusion: Local administration of Dexamethasone through three different routes is beneficial in decreasing postoperative sequelae following third molar surgery. Pterygomandibular space injection of Dexamethasone resulted in earlier resolution of pain, and less facial edema and trismus at the second postoperative day compared to the submucosal injection and transalveolar application. However, at one week the difference in measurements of the three variables between the groups was not significant. (AU)

Objetivo: O objetivo deste estudo foi fornecer evidências para comparar a eficácia de três diferentes vias de administração local de dexametasona na dor pós-operatória, edema e trismo após a remoção cirúrgica do terceiro molar inferior impactado. Material e Métodos: Quarenta e cinco pacientes foram submetidos à remoção cirúrgica de terceiros molares inferiores impactados e distribuídos aleatoriamente no pós-operatório em 3 grupos: 8 mg de dexametasona injetados na submucosa vestíbular próximo ao local da cirurgia (grupo I), 8 mg de dexametasona injetados no espaço pterigomandibular (grupo II) e 10 mg de pó de dexametasona aplicados no local da extração, após o controle do sangramento (grupo III). Edema facial e abertura interincisal máxima foram medidos no pré-operatório. A dor foi medida pela resposta do paciente a uma escala visual analógica. Percepção de dor, edema facial e trismo foram avaliados por uma semana de pós-operatório. Resultados: Não houve diferença significativa entre os três grupos em relação à dor após 1, 2, 5, 7 dias de acompanhamento. No entanto, o grupoII mostrou menos dor em 3 e 4 dias. A diferença entre as medidas de edema não foi significativa nos três grupos em 1, 5, 7 dias, embora nos grupos I e II o edema cedeu a partir do dia 2. Quanto ao trismo, os grupos I e III apresentaram medida de abertura interincisal máxima inferior estatisticamente significativa do que o grupo II depois de dois dias. Conclusão: A administração local de dexametasona por três vias diferentes é benéfica na redução das sequelas pós-operatórias após a cirurgia do terceiro molar. A injeção de dexametasona no espaço pterigomandibular resultou na resolução mais precoce da dor e menos edema facial e trismo no segundo dia de pós-operatório em comparação com a injeção submucosa e a aplicação transalveolar. No entanto, em uma semana, a diferença nas medidas das três variáveis entre os grupos não foi significativa.(AU)

Errores de administración de medicamentos en enfermería / Medication administration errors in nursing

Introducción: los errores en el proceso de administración de medicamentos (EPAM) corresponden a múltiples factores, como: la condición de vulnerabilidad del usuario, dinámica que se vive dentro de las propias unidades y confusión en la terapia farmacológica, entre otros. El mayor porcentaje de los EPAM se produce en la etapa de administración, por lo que el rol de enfermería es fundamental. Existen diversas estrategias destinadas a la prevención, con distintos niveles de complejidad, en términos de implementación. Objetivo: conocer las múltiples causas que llevan al personal de enfermería a realizar una mala praxis en el proceso de administración de medicamentos. Material y métodos: se realizó una revisión de literatura mediante la búsqueda de artículos científicos en las siguientes bases de datos: Cochrane, Embase, Medline y SciELO. Conclusión: es indispensable hacer conciencia de la responsabilidad en los profesionales de enfermería para cumplir con las normas en la administración de medicamentos, con los "10 correctos" y evitar riesgos innecesarios a los pacientes que pueden en algunos casos ocasionar consecuencias graves.

Study of the Effect of Route of Administration of Mesenchymal Stem Cells on Cisplatin-Induced Acute Kidney Injury in Sprague Dawley Rats

BACKGROUND AND OBJECTIVES: Mesenchymal stem cells (MSCs) have been shown to ameliorate cisplatin-induced acute kidney injury (AKI). The present study compares the efficacy of different routes of MSCs administration on kidney damage and regeneration after cisplatin-induced AKI. METHODS: A single intraperitoneal injection of cisplatin (5 mg/kg) was used to induce AKI in 160 rats. MSCs (5×106) were given by either intravenous, intra-arterial or kidney sub capsular injection one day after cisplatin injection. Suitable control groups were included. Rats were sacrificed at 4, 7, 11 and 30 days after cisplatin injection. Kidney function parameters, kidney tissue oxidative stress markers, and scoring for renal tissue injury, regeneration and chronicity were all determined. RESULTS: MSCs by any routes were able to ameliorate kidney function deterioration and renal tissue damage induced by cisplatin. The overall results of the three routes were equal. Differences between the different routes in one parameter were transient and inconsistent with other parameters. CONCLUSION: Changing the route of MSCs injection does not have a major influence on the outcome. Future evaluation should focus on differences between the routes of administration considering the long term safety.

Influence of different routes of administration on vaccine efficiency of peptide-pulsed dendritic cells / 中国免疫学杂志

Objective:To investigate the influence of different routes of administration on vaccine efficiency of peptide-pulsed dendritic cells(DC).Methods:Immunization of syngeneic C57BL/6 mice with bone marrow-derived murine DC pulsed with SIINFEKL, a MHC class Ⅰ-restricted peptide from chicken ovalbumin(OVA) sited at 257-264 amino acid residuals were performed via subcutaneous(s.c.), intramuscular(i.m.), intravenous(i.v.), and intraperitoneal(i.p.) administration, respectively. Seven days later the mice were sacrificed and the splenocytes were prepared to analyze antigen-specific CTL lysis for target cells and IFN-?-producting CD8+T lymphocytes using in vivo CTL assay and intracellular cytokine staining(ICS), respectively.Results:The results from in vivo CTL assay showed that the CTL lysis activities were 37.3%?7.3%, 10.8%?2.3%, 56.9%?3.6% and 61.0%?4.2% via s.c., i.m., i.v., and i.p. administration, respectively. Similarly, ICS showed that IFN-?-producting cells in total CD8+T lymphocytes were 0.43%?0.09%, 0.85%?0.12%, 0.76%?0.14% and 0.15%?0.04%, respectively.Conclusion:Different routes of administration has an obvious influence on vaccine efficiency of peptide-pulsed DC. The i.p. immunization with DC elicites the strongest CTL lysis activity, i.v. immunization is next, and s.c., in particular i.m. is the worst, suggesting that i.p. administration may be a safe and effective route for immunization with peptide-pulsed DC against cancers in a mice model.
