ABSTRACT

A randomized clinical trial is conducted to compare the efficacy of aloe vera gel and 0.1% triamcinolone acetonide in the management of symptomatic oral lichen planus. The study involved a sample of 30 patients (16 males and 14 females) diagnosed with oral lichen planus clinically and histopathologically, who were randomly allocated into two groups. Patients in Group A were administered Aloe vera gel, while those in Group B received 0.1% triamcinolone acetonide as a local application. After the treatment, the results obtained were statistically analyzed and tabulated. Research results indicate tha t applying Aloe vera topically is just as effective as using topical triamcinolone acetonide, suggesting that Aloe vera may be a preferable replacement due to its safety profile in comparison to 0.1% triamcinolone acetonide.


Se llevó a cabo un ensayo clínico aleatorizado para comparar la eficacia del gel de aloe vera y el acetónido de triamcinolona al 0,1% en el tratamiento del liquen plano oral sintomático. El estudio involucró una muestra de 30 pacientes (16 hombres y 14 mujeres) diagnosticados clínica e histopatológicamente con liquen plano oral, que fueron asignados aleatoriamente en dos grupos. A los pacientes del grupo A se les administró gel de aloe vera, mientras que los del grupo B recibieron acetónido de triamcinolona al 0,1% como aplicación local. Después del tratamiento, los resultados obtenidos fueron analizados estadísticamente y tabulados. Los resultados de la investigación indican que la aplicación tópica de Aloe vera es tan efectiva como usar acetónido de triamcinolona tópico, lo que sugiere que el Aloe vera puede ser un reemplazo preferible debido a su perfil de seguridad en comparación con el acetónido de triamcinolona al 0,1%.

ABSTRACT

RESUMO Objetivo: Avaliar o efeito do colírio de brimonidina 0,2% na redução da hiperemia e do sangramento ocular durante as cirurgias de estrabismo, em comparação com o colírio de nafazolina 0,025% + feniramina 0,3%. Métodos: Foram avaliados 14 pacientes com estrabismo e indicação de correção cirúrgica bilateral. Foi instilado antes do procedimento, de forma aleatória, um colírio em cada olho dos pacientes avaliados. A análise subjetiva da hiperemia conjuntival e do sangramento perioperatório foi realizada de forma duplo-cega, por dois cirurgiões. A avaliação objetiva do nível de hiperemia conjuntival foi realizada por análise das imagens obtidas por meio do software ImageJ®. Resultados: A análise de modelos multivariados de efeito misto indicou diferenças estatisticamente significantes entre os grupos em relação à hiperemia (avaliador 2) e ao sangramento intraoperatório (avaliadores 1 e 2), com maiores escores nos casos tratados com colírio de nafazolina + feniramina. Entretanto, não houve diferença estatística na análise objetiva realizada por meio da saturação de cores obtidas pelo programa ImageJ®. Conclusão: O colírio de brimonidina pode ser superior ao colírio de nafazolina + feniramina na redução do sangramento, levando-se em conta apenas a análise subjetiva.


ABSTRACT Objective: To evaluate the effect of 0.2% brimonidine eye drops in reducing hyperemia and ocular bleeding during strabismus surgeries, in comparison with 0.025% naphazoline + 0.3% pheniramine eye drops. Methods: Fourteen patients with strabismus and indication for bilateral surgical correction were evaluated. Before the procedure, the eye drops were instilled randomly in each eye of the evaluated patients. The subjective analysis of conjunctival hyperemia and perioperative bleeding was performed in a double-blind manner, by 02 surgeons. The objective assessment of the level of conjunctival hyperemia was performed by analyzing the images obtained using the ImageJ® software. Results: The analysis of multivariate mixed effect models indicated statistically significant differences between the groups in relation to hyperemia (rater 2) and intraoperative bleeding (raters 1 and 2) with higher scores in cases treated with naphazoline + pheniramine eye drops. However, there were no statistically significant differences in the objective analysis of color saturation obtained by the ImageJ® program. Conclusion: Brimonidine eye drops may be superior to naphazoline + pheniramine eye drops in reducing bleeding, taking into account the subjective analysis only.

ABSTRACT

ABSTRACT BACKGROUND: Caustic ingestion and development of esophageal strictures are recognized major public health problems in childhood. Different therapeutic methods have been proposed in the management of such strictures. OBJECTIVE: To evaluate efficacy and risk of endoscopic topical application of mitomycin C in the treatment of caustic esophageal strictures. METHODS: We searched MEDLINE, EMBASE, Central Cochrane, and LILACS databases. The outcomes evaluated were dysphagia resolution rate, number of dilations performed in resolved cases, and the number of dilations performed in all patients. RESULTS: Three randomized clinical trials were included for final analysis with a total of 190 patients. Topical mitomycin C application group showed a significant increase in dysphagia resolution rate, corresponding to a 42% higher dysphagia resolution as compared to endoscopic dilation alone, with statistical significance between the two groups (RD: 0.42 - [CI: 0.29-0.56]; P-value <0.00001). The mean number of dilations performed in resolved cases were significantly less in the topical mitomycin C application group, compared to endoscopic dilations alone, with statistical significance between the two groups (MD: 2.84 [CI: 1.98-3.69]; P-value <0.00001). When comparing the number of dilations in all patients, there was no statistical difference between the two groups (MD: 1.46 [CI: -1.53-4.44]; P-value =0.34). CONCLUSION: Application of topical mitomycin C with endoscopic dilations in caustic esophageal strictures was more effective in dysphagia resolution than endoscopic therapy alone in the pediatric population. Moreover, topical mitomycin C application also reduced the number of dilation sessions needed to alleviate dysphagia without rising morbidity.


RESUMO CONTEXTO: A ingestão de soda cáustica e o desenvolvimento de estenoses esofágicas são reconhecidos como importantes problemas de saúde pública na infância. Diferentes métodos terapêuticos têm sido propostos no manejo dessas estenoses. OBJETIVO: Avaliar a eficácia e o risco da aplicação endoscópica tópica de mitomicina C no tratamento de estenoses esofágicas cáusticas. MÉTODOS: Buscamos as bases de dados MEDLINE, EMBASE, Central Cochrane e LILACS. Os desfechos avaliados foram taxa de resolução da disfagia, número de dilatações realizadas nos casos resolvidos e número de dilatações realizadas em todos os pacientes. RESULTADOS: Três ensaios clínicos randomizados foram incluídos para análise final com um total de 190 pacientes. O grupo de aplicação de mitomicina C tópica apresentou aumento significativo na taxa de resolução da disfagia, correspondendo a uma resolução da disfagia 42% maior em comparação à dilatação endoscópica isolada, com significância estatística entre os dois grupos (RD: 0,42 - [IC: 0,29-0,56]; P-valor <0,00001). O número médio de dilatações realizadas em casos resolvidos foi significativamente menor no grupo de aplicação tópica de mitomicina C, em comparação com as dilatações endoscópicas isoladas, com significância estatística entre os dois grupos (MD: 2,84 [IC: 1,98-3,69]; P-valor <0,00001). Ao comparar o número de dilatações em todos os pacientes, não houve diferença estatística entre os dois grupos (MD: 1,46 [IC: -1,53-4,44]; valor de P=0,34). CONCLUSÃO: A aplicação de mitomicina C tópica com dilatações endoscópicas em estenoses esofágicas cáusticas foi mais eficaz na resolução da disfagia do que a terapia endoscópica isolada na população pediátrica. Além disso, a aplicação tópica de mitomicina C também reduziu o número de sessões de dilatação necessárias para aliviar a disfagia sem aumentar a morbidade.

ABSTRACT

Abstract The diagnosis of genital ulcers remains a challenge in clinical practice. Lipschütz ulcer is a non-sexually transmitted rare and, probably, underdiagnosed condition, characterized by the sudden onset of vulvar edema along with painful necrotic ulcerations. Despite its unknown incidence, this seems to be an uncommon entity, with sparse cases reported in the literature. We report the case of an 11-year-old girl who presented at the emergency department with vulvar ulcers. She denied any sexual intercourse. The investigation excluded sexually transmitted infections, so, knowledge of different etiologies of non-venereal ulcers became essential. The differential diagnoses are extensive and include inflammatory processes, drug reactions, trauma, and malignant tumors. Lipschütz ulcer is a diagnosis of exclusion. With the presentation of this case report, the authors aim to describe the etiology, clinical course, and outcomes of this rare disease, to allow differential diagnosis of genital ulceration.

ABSTRACT

Resumo Introdução: A epistaxe recorrente é uma doença comumente vista por especialistas em otorrinolaringologia, médicos de emergência e pediatras. O fato de que muitas modalidades de tratamento estejam sendo pesquisadas e nenhum método único de tratamento seja universalmente aceito apoiam ainda mais essa informação. Objetivo: Comparar a eficácia clínica do uso de pomada antisséptica tópica, pomada descongestionante tópica e tratamentos de cauterização química, que são frequentemente usados em epistaxe anterior recorrente, tanto isoladamente como em combinação. Método: Entre agosto de 2017 e fevereiro de 2018, 137 pacientes diagnosticados com epistaxe anterior recorrente foram divididos aleatoriamente em 5 grupos. O grupo I foi tratado com pomada antisséptica tópica, o grupo II com pomada descongestionante tópica, o grupo III foi submetido a cauterização química, o grupo IV foi tratado com pomada antisséptica tópica + cauterização química e o grupo V com pomada descongestionante tópica + tratamento de cauterização química. Todos os pacientes foram contatados por telefone 2 semanas e um mês após o tratamento e perguntados sobre a presença (falha) ou ausência (sucesso) de pelo menos um episódio de epistaxe. Pacientes com comorbidades foram excluídos. O sucesso do tratamento foi analisado estatisticamente. Resultados: Não houve diferença significante (p > 0,05) entre os grupos em relação à taxa de sucesso no 15° dia após o tratamento. Os grupos IV e V tiveram maiores taxas de sucesso no 30° dia após o tratamento em comparação com os grupo I e II (p < 0,05). No grupo III, o sucesso do tratamento no 30° dia não foi diferente dos outros 4 grupos (p > 0,05). Conclusão: Embora o número de pacientes que melhoraram com a cauterização química (grupo III) tenha sido maior em nosso estudo, nenhuma diferença significante foi observada nas modalidades de tratamento único (grupos I - III) no 14° dia e no 30° dia após o tratamento. Embora não tenha sido observada diferença estatisticamente significante entre os tratamentos combinados (grupos IV - V) e os tratamentos simples (grupos I - III) na 2ª semana após o tratamento, os tratamentos combinados foram significantemente mais eficazes no 1° mês.

ABSTRACT

Abstract Introduction Mitomycin C is a natural antibiotic that has been used to inhibit the proliferation of fibroblasts in scar tissue. Objective To evaluate the effectiveness and safety of topical Mitomycin C as an adjuvant in the endoscopic treatment of laryngotracheal stenoses. Data synthesis A systematic review of experimental or observational studies that have evaluated the treatment of laryngotracheal stenoses with the use of topical Mitomycin C was performed. Databases researched: LILACS, PubMed, Embase, Cochrane and Web of Science. Outcomes: resolution (symptom-free time ≥ one year), number of procedures required, and complications resulting from the procedure. A total of 15 studies (involving 387 patients) were selected. Mitomycin C was administered to every patient in 11 studies, and in 4 other studies, the patients were separated into 2 groups, 1 receiving mitomycin C, and the other not. The resolution of the stenosis evaluated in 12 studies in which the patients received mitomycin C was of 69% (95% confidence interval [95%CI]: 61-76%; I2 = 17.3%). A total of 52% of the patients (95%CI: 39-64%, 11 studies; I2 = 64.7%) were submitted to a single endoscopic procedure, and 48% (95%CI: 36-61%, 11 studies; I2 = 64.7%) were submitted to more than 1 procedure. Complications (mediastinal and subcutaneous emphysema, dysphonia, laceration or vocal fold paralysis and acute light obstruction) were reported in 9% of the patients (95%CI: 3-18%, 9 studies; I2 = 79.8%). Conclusions The evidence suggests that mitomycin C is an effective and safe option in the endoscopic treatment of laryngotracheal stenosis.

ABSTRACT

Abstract With the development of new cancer therapies, systemic toxicity profile and effects on survival achieved an important improvement. However, a constellation of toxicities has emerged, even more remarkably, cutaneous adverse events. This report, developed by a board of Brazilian experts in oncodermatology, aims to establish a guideline for the dermatological care of oncologic patients. When possible, evidence-based recommendations were made, but in many cases, when strong evidence was not available, a consensus was reached, based on some data supporting therapies combined with personal experiences.

ABSTRACT

Abstract Introduction Tranexamic acid is a hemostatic agent, which inhibits fibrin degradation, which may be beneficial in controlling bleeding during surgery. Objectives The purpose of this study was to provide a meta-analysis and review of the effects of tranexamic acid on hemorrhage and surgical fields and side effects on patients during endoscopic sinus surgery. Methods Two authors independently searched six databases (Medline, Scopus, Embase, Web of Science, Google Scholar and Cochrane library) from the start of article collection until July 2018. Postoperative complications such as intraoperative bleeding, operative time, hypotension, nausea, vomiting, and coagulation profile were included in the analysis of tranexamic acid (Treatment Group) and placebo (Control Group) during the operation. Results The amount of blood loss during surgery was statistically lower in the treatment group compared to the placebo group, and the surgical field quality was statistically higher in the treatment group than in the placebo group. On the other hand, there was no significant difference in operation time, hemodynamics, or coagulation profile between groups. In addition, tranexamic acid had no significant effect on vomiting and thrombosis compared to the Control Group. Conclusion This meta-analysis has shown that topical administration of tranexamic acid can reduce the amount of bleeding during surgery and improve the overall quality of the surgery. Hemodynamic instability during surgery, vomiting after surgery, or abnormal clotting profile were not reported. Additional studies are needed to confirm the results of this study because there are fewer studies.


Resumo Introdução O ácido tranexâmico é um agente hemostático, que inibe a degradação da fibrina e pode ser benéfico no controle do sangramento durante a cirurgia. Objetivos Fazer uma metanálise e revisão dos efeitos do ácido tranexâmico na hemorragia e nos campos cirúrgicos e efeitos colaterais em pacientes durante a cirurgia endoscópica do seio nasal. Método Dois autores realizaram independentemente uma busca em seis bancos de dados (Medline, Scopus, Embase, Web of Science, Google Scholar e Cochrane) desde o início da coleta de artigos até julho de 2018. Complicações pós-operatórias como sangramento intraoperatório, tempo operatório, hipotensão, náusea, vômitos e perfil de coagulação foram incluídos na análise do ácido tranexâmico (grupo de tratamento) e placebo (grupo controle) durante a cirurgia. Resultados A quantidade de perda de sangue durante a cirurgia foi estatisticamente menor no grupo de tratamento comparado com o grupo placebo e a qualidade do campo cirúrgico foi estatisticamente maior no grupo de tratamento do que no grupo placebo. Por outro lado, não houve diferença significante no tempo cirúrgico, hemodinâmica ou perfil de coagulação entre os grupos. Além disso, o ácido tranexâmico não teve efeito significante na ocorrência de vômitos e trombose em comparação ao grupo controle. Conclusão Esta metanálise mostrou que a administração tópica de ácido tranexâmico pode reduzir a quantidade de sangramento durante a cirurgia e melhorar a qualidade geral dela. Instabilidade hemodinâmica durante a cirurgia, vômitos após a cirurgia ou perfil de coagulação anormal não foram relatados. Estudos adicionais são necessários para confirmar os resultados desta pesquisa, porque há poucos estudos na literatura.

ABSTRACT

In this study, naftifine (a topical antifungal drug) loaded poly(vinyl) alcohol (PVA)/sodium alginate (SA) nanofibrous mats were prepared using the single-needle electrospinning technique. The produced nanofibers were crosslinked with glutaraldehyde (GTA) vapor. The morphology and diameter of the electrospun nanofibers were studied by scanning electron microscopy (SEM). SEM images showed the smoothness of the nanofibers and indicated that the fiber diameter increased with crosslinking and drug loading. Atomic force microscopy (AFM) images confirmed the uniform production of the scaffolds, and elemental mapping via energy dispersive X-ray spectroscopy (EDS) showed the uniform distribution of the drug within the nanofibers. An attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy study demonstrated that naftifine has sufficient secondary interactions with the polymer blend. The crosslinking treatment decreased the burst drug release effectively and the release mechanism followed Korsmeyer-Peppas Super Case-II transport. Overall, these findings suggest the potential use of naftifine-loaded PVA/SA nanofibers as a topical antifungal drug delivery system.

ABSTRACT

Intentar el tratamiento retentivo de material protésico ante heridas quirúrgicas infectadas por gérmenes resistentes es objeto de debate, especialmente cuando el agente causal es un Staphylococcus aureus resistente a meticilina (SARM). Una paciente diabética y con obesidad tipo I sufrió infección de la herida quirúrgica tras artroplastia de rodilla que no evolucionó bien con antibioterapia empírica y terapia hiperosmolar. Se planificó una reintervención que fue demorada por motivos extramédicos (falta de terapia de presión negativa para cubrir la herida postoperatoria, pues se preveía no poder realizar cierre primario). Mientras se conseguía este material, y tras obtener el consentimiento de la paciente, se iniciaron irrigaciones de la herida con sevoflurano tópico off-label, pues ese fármaco ha mostrado capacidad antimicrobiana. La evolución clínica fue excelente desde el inicio a pesar de que en el cultivo se aisló un SARM resistente a la antibioterapia empírica, por lo que se desestimó la reintervención y se continuó con sevoflurano tópico junto a la antibioterapia dirigida por antibiograma, lográndose la curación completa de la herida tras 6 semanas. Durante ese tiempo, la paciente no experimentó ningún efecto adverso atribuible al sevoflurano. El sevoflurano tópico aparece como una valiosa nueva opción terapéutica ante heridas postoperatorias infectadas, especialmente cuando los gérmenes causantes son resistentes a los antibióticos convencionales.


It is challenging to try a retentive treatment of prosthetic material superinfected by resistant microorganisms, especially when the causative agent is a methicillin-resistant Staphylococcus aureus (MRSA). A diabetic, obese female patient suffered from a postoperative wound infection after a knee arthroplasty. Initial treatment with antibiotics and hyperosmolar therapy failed and clinical evolution was no good. Surgery was scheduled, but it was delayed due to nonmedical reasons (lack of negative-pressure therapy to cover the wound since primary wound closure was anticipated to be very improbable to perform). While waiting for this therapy, off-label irrigations with topical sevoflurane were started after obtaining written consent, since this drug has exhibited antimicrobial properties. Clinical evolution turned out to be excellent since the very beginning, even though a MRSA resistant to the antibiotics empirically administered was isolated. Thus, surgery was discarded, and culture-guided antibiotic therapy was added to topical sevoflurane, which was followed by a complete healing of the wound after 6 weeks. Sevoflurane treatment was well tolerated as the patient reported no adverse effects. Therefore, treating postsurgical wounds with topical sevoflurane appears as a valuable new alternative, especially when infections are caused by microorganisms resistant to conventional antibiotics.

ABSTRACT

Abstract Objective: The goal of the present study was to determine the effect of systemic and topical ozone application on alveolar bone loss (ABL) by evaluating the effect of Hypoxia-inducible factor −1 alpha (HIF-1-α) and receptor activator of NF-kB ligand (RANKL)-positive cells on histopathological and immunohistochemical changes in a rat periodontitis model. Methodology: Thirty male Wistar rats were divided into three groups: 1) Group C (control group); 2) Group SO (systemic ozone group) and 3) Group TO (topical ozone group). Experimental periodontitis was induced with a 3/0 silk suture placed at the mandibular left first molars of rats, and the suture was removed 14 days later. Ozone gas was injected intraperitoneally (0.7 mg/kg) in SO group. Topical ozone application protocol was performed using an ozone generator at 80% concentration (4th grade) 90- degree probe for the duration of 30 s. Both ozone applications were carried out for two weeks at intervals of two days. Histomorphometric and immunohistochemical analysis were performed. Results: ABL was significantly lower in Group SO compared to Group C (p: 0.0052). HIF-1α- positive cells were significantly lower in Group TO than in Group C (p: 0.0043). RANKL-positive cells were significantly lower in Group SO and in Group TO compared to the control group (p: 0.0033, p: 0.0075, respectively). Conclusion: Both ozone applications decreased RANKL-positive cell counts, TO application decreased HIF-1-α positive cells counts, and SO application was found to be more effective in reducing ABL compared to control group.

ABSTRACT

Introducción: Aproximadamente 14.5% de los pacientes oncológicos presentan una herida neoplásica maligna (HNM) debido al aumento en la tasa de supervivencia y un 85% refieren dolor en la HNM. En la práctica clínica este es el síntoma con menos uso de tratamientos tópicos. Objetivo: Sintetizar la evidencia disponible relacionada con la efectividad de los tratamientos tópicos para el control del dolor en la HNM en adultos. Método: Se realizó una Revisión de efectividad, siguiendo la metodología JBI y las fuentes consultadas fueron: CINAHL, LILACS, Embase, Scopus, Web of Science, PubMed, Cochrane, NICE, Scopus y JBI, así como otras fuentes, en inglés, portugués y español, sin límites de tiempo. Los registros que cumplieron con los criterios de inclusión fueron revisados por relevancia con respecto a los objetivos del estudio. Se realizaron valoraciones de la calidad metodológica mediante los instrumentos del JBI y se extrajeron los datos por las revisoras de forma independiente; no se presentó desacuerdo. Resultados: Se incluyeron 4 ensayos clínicos aleatorizados, un estudio sobre el tratamiento con crema lidocaína y prilocaína al 5% y el otro sobre la morfina tópica al 0,2% los dos comprobaron un efecto analgésico; los otros dos estudios no arrojaron resultados primarios significativos en el control del dolor. Conclusiones: La crema de lidocaína y prilocaína al 5% y la morfina tópica al 0,2% se presentan altamente eficaces y seguras para el control del dolor en las HNM. Sin embargo, se requieren nuevos estudios para fortalecer el conocimiento y la práctica clínica


Introduction: Approximately 14.5% of cancer patients present a malignant fungating wound (MFW) due to the increase in the survival rates, among which 85% report pain in the MFW. In current clinical practice, pain in MFW is the symptom for which topical treatments are least used. Objective: Synthesize the available evidence related to the effectiveness of topical treatments for MFW pain control in adults. Methods: We did a review of effectiveness, following the JBI methodology and the databases searched were: CINAHL, LILACS, Embase, Scopus, Web of Science, PubMed, Cochrane, NICE, Scopus and JBI, as well as unpublished studies??, in English, Portuguese and Spanish, without time limits. The records that met the inclusion criteria were reviewed for relevance to the study objectives. Methodological quality assessments were made using the JBI instruments and the data were extracted by two independent reviewers, with no disagreements. Results: Four randomized clinical trials were included; one study on topical treatment with lidocaine and prilocaine 5% and another one with topical morphine 0,2% confirmed an analgesic effect; the other two studies had no significant primary outcomes in pain control. Conclusions: Lidocaine and prilocaine cream 5% and topical morphine 0.2% showed highly effective and safe for HNM pain control. However, further studies are required to strengthen clinical knowledge and practice

ABSTRACT

Abstract Background: Myofascial pain syndrome is a common cause of musculoskeletal pain. The objective of this study was to evaluate the potential analgesic action of 8% capsaicin cream for topical use in patients with myofascial pain syndrome. Methods: Initially, cream formulations of PLA (Placebo) and CPS (Capsaicin 8%) were developed and approved according to the current requirements of the health authority agency. The 40 participating patients were randomly assigned to the PLA and CPS groups in a double-blind fashion. Before the creams were topically administered, according to the allocation group, the local anesthetic was used for a period of 50 minutes directly in the area of interest. The cream was applied to the area of the skin over the trigger point, represented by the area with pain at palpation, in an amount of 10 g for 30 minutes in a circular area of 24 mm diameter. Subsequently, the cream was removed and the skin tolerability parameters were evaluated. The pain was measured before and during the formulation application, as well as at 1 hour, 7 days, 30 days, and 60 days after the procedure, evaluated using a verbal numerical scale (from 0 to 10: with 0 = no pain and 10 = worst pain imaginable). Results: No patient in PLA Group had hyperemia or burning sensation at the site of application, while 85% of patients in CPS Group had hyperemia or burning sensation at 15 minutes. These complaints disappeared 24 hours after the cream was removed. The pain score in CPS Group decreased steadily up to the 60th day of evaluation (p < 0.0001). Conclusion: Application of the formulations did not cause macroscopic acute or chronic skin lesions in patients, and the 8% capsaicin formulation was beneficial and well tolerated.


Resumo Justificativa: A síndrome da dor miofascial é uma causa comum de dor musculoesquelética. O objetivo deste estudo foi avaliar a potencial ação analgésica de 8% do creme de capsaicina para uso tópico em pacientes com síndrome da dor miofascial. Métodos: Inicialmente, as formulações de creme de PLA (Placebo) e CPS (Capsaicina 8%) foram desenvolvidas e aprovadas de acordo com os requisitos atuais da agência de autoridade de saúde. Os 40 pacientes participantes foram distribuídos aleatoriamente e de forma duplo-cega para os grupos PLA e CPS. Antes dos cremes serem administrados topicamente, de acordo com o grupo de alocação, o anestésico local foi usado por um período de 50 minutos diretamente na área de interesse. A administração ocorreu na área da pele sobre o ponto-gatilho, o qual apresentou a área dolorida à palpação, em uma quantidade de 10 g por 30 minutos em área circular com diâmetro de 24 mm. Posteriormente, o creme foi removido e os parâmetros de tolerabilidade à pele foram avaliados. A dor foi medida antes e durante a aplicação da formulação, bem como 1 hora, 7 dias, 30 dias e 60 dias após o procedimento avaliado pela escala numérica verbal (0 a 10, com zero sem dor e dez a pior dor imaginável). Resultados: Nenhum paciente no grupo PLA experimentou hiperemia ou sensação de queimação no local de aplicação do creme, enquanto 85% dos que experimentaram no grupo CPS apresentaram hiperemia ou sensação de queimação 15 minutos. Essas queixas desapareceram 24 horas após a remoção do creme. O escore de dor no grupo CPS diminui de forma sustentada até o 60° dia de avaliação (p < 0,0001). Conclusão: A administração das formulações não causou lesões cutâneas agudas ou crônicas macroscópicas nos pacientes e a formulação de 8% de capsaicina foi benéfica e bem tolerada.

ABSTRACT

ABSTRACT This study aims to describe a challenging clinical case of a patient with a neurotrophic and exposure corneal ulcer. A 75-year-old male patient, with history of right eye (RE) limbic stem-cell insuficiency due to complications of recurrent herpetic keratitis, underwent successful limbic stem-cell transplantation in 2008. In 2010, an uneventful penetrating keratoplasty was performed. After a cataract phacoemulsification surgery with intraocular lens implantation done in 2011, best corrected visual acuity was 20/20, and remained stable until 2015. In July 2015, the patient developed right facial nerve palsy and two months later, presented with an extensive central corneal ulcer, with a significant thinning of central stroma, without infection signs, but with an imminent risk of perforation. Treatment with topical ofloxacin and intensive ocular lubrification was started in association with permanent ocular oclusion. Due to lack of any clinical improvement, treatment with RGTA [Poli (carboximetilglucose) sulfate, dextrano T40] (Cacicol®, Thea) was started. After two weeks of treatment, a complete reepithelization and partial stromal filling was observed. Continued monitoring and treatment with artificial tears was maintained, with no recurrence observed. There is an unmet need for a medical therapy that could help corneal neurotrophic ulcers to heal. The presented clinical case shows that the approach of targeting extracellular matrix can be effective in the reepithelialization of neurotrophic and exposure corneal ulcer that do not respond to conventional treatments.


RESUMO Este trabalho relata um caso clínico desafiante de doente com uma úlcera de córnea neurotrófica e de exposição. Doente do sexo masculino, de 75 anos, com antecedentes de queratites herpéticas de repetição no olho direito (OD), complicadas com o desenvolvimento de uma insuficiência límbica, foi submetido com sucesso a transplante de células límbicas em 2008. Em 2010 foi submetido a queratoplastia penetrante e em 2011, após realização de cirurgia de catarata, apresentava uma melhor acuidade visual corrigida (MAVC) de 20/20. A MAVC manteve-se estável até Julho de 2015, altura em que desenvolveu paresia facial periférica à direita. Dois meses depois, o doente desenvolveu uma úlcera de córnea central extensa, com adelgaçamento significativo do estroma central, sem sinais de infeção, mas com risco iminente de perfuração. Foi iniciado tratamento tópico com ofloxacina, lubrificação intensiva e oclusão ocular contínua. Por ausência de melhoria clínica, foi iniciado tratamento tópico com um RGTA [Poli (carboximetilglucose) sulfato, dextrano T40] (Cacicol®, Thea). Após duas semanas de tratamento, observou-se uma reepitelização completa e regeneração parcial do estroma. Foi mantida monitorização regular e tratamento com lágrimas artificiais, sem recidiva do quadro clínico. Há uma grande necessidade de tratamentos médicos que possam ajudar na regeneração de úlceras de córnea neurotróficas e de exposição. O caso clínico apresentado sugere que os fármacos que têm por alvo a matrix extracelular poderão ser eficazes na reepitelização de úlceras de córnea neurotróficas e de exposição que não respondem ao tratamento convencional.

ABSTRACT

Abstract: CHILD syndrome (Congenital Hemidysplasia, Ichthyosiform erythroderma, Limb Defects) is a rare X-linked dominant disease. The authors report a 2-month-old patient presenting with typical features of CHILD syndrome that was treated with a topical solution containing cholesterol and lovastatin, with complete clearance of her CHILD nevus. The changes in skin lipid metabolism that explain the CHILD ichthyosiform nevus and their correction through topical application of cholesterol and lovastatin are discussed.

ABSTRACT

Abstract BACKGROUND: Tacrolimus, for its activity on modulation of collagen production and fibroblast activity, may have a role in the prevention of hypertrophic scars. OBJECTIVES: Evaluate macroscopic, microscopic, metabolic, laboratory effects and side effects of the use of topical tacrolimus ointment, in different concentrations, in the prevention of hypertrophic scars. METHODS: Twenty-two rabbits were submitted to the excision of 2 fragments of 1 cm of each ear, 4 cm apart, down to cartilage. The left ear of the animals was standardized as control and Vaseline applied twice a day. The right ear received tacrolimus ointment, at concentrations of 0.1% on the upper wound and 0.03% on the lower wound, also applied twice a day. Macroscopic, microscopic, laboratory criteria and the animals' weight were evaluated after 30 days of the experiment. RESULTS: Wounds treated with tacrolimus, at concentrations of 0.1% and 0.03%, when compared to control, showed a lower average degree of thickening (p = 0.048 and p <0.001, respectively). The average of scar thickness and lymphocyte, neutrophil and eosinophil concentrations are lower in the treated wounds compared to the control (p <0.001, p=0.022, p=0.007, p=0.044, respectively). The mean concentration of lymphocytes is lower in wounds treated with a higher concentration of the drug (p=0.01). STUDY LIMITATIONS: experiment lasted only 30 days. CONCLUSIONS: Tacrolimus at the 2 concentrations evaluated reduced the severity of inflammatory changes and positively altered the macroscopic aspect of the scar in the short term. Its use was shown to be safe, with no evidence of systemic or local adverse effects.
