Myroxylon pereirae resin (balsam of Peru) - A critical review of the literature and assessment of the significance of positive patch test reactions and the usefulness of restrictive diets.

In this article, contact allergy to Myroxylon pereirae resin (MP) (balsam of Peru) is reviewed. The topics presented include the uses, the chemical composition, the frequency of sensitization, the relevance of positive reactions, the MP-containing products causing allergic contact dermatitis, co-reactivity with other fragrance and non-fragrance materials, the sensitizers, the usefulness of MP as a "marker" of fragrance allergy, and the effectiveness of, and indications for, "balsam-restrictive" diets. Sensitization to MP occurs in 4% to 8% of patients routinely tested for suspected contact dermatitis. There are few adequate data on relevance. Topical pharmaceuticals were formerly, but are not today, important sources of sensitization. Cosmetics and foods or drinks are hardly ever products responsible for sensitization to MP. Positive patch test reactions in the large majority probably result from previous sensitization to MP constituents because of their presence in fragrances and fragranced products, MP thereby acting as marker (or "indicator") of fragrance allergy. However, fragrance mix I is a more sensitive marker, and the added diagnostic value of testing with MP is unknown. The allergenic ingredients of MP include isoeugenol, eugenol and cinnamyl alcohol, but there are other-largely unknown-chemicals that are responsible for contact allergy. Suggestions are given for further research to address questions thus far unanswered and to improve patient care.

Copaiba oil influences ventral hernia repair with Vicryl® mesh?

BACKGROUND: The use of meshes in hernia surgical repair promoted revolution in the surgical area; however, some difficulties had come, such as a large area of fibrosis, greater postoperative pain and risk of infection. The search for new substances that minimize these effects should be encouraged. Medicinal plants stand out due possible active ingredients that can act on these problems. AIM: To check the copaiba oil influence in the repair of abdominal defects in rats corrected with Vicryl(c) mesh. METHOD: Twenty-four Wistar rats were submitted to an abdominal defect and corrected with Vicryl(c) mesh. They were distributed into two groups: control and copaíba via gavage, administered for seven days after surgery. The analysis of the animals took place on 8, 15 and 22 postoperative days. It analyzed the amount of adhesions and microscopic analysis of the mesh. RESULTS: There was no statistical difference regarding the amount of adhesions. All animals had signs of acute inflammation. In the control group, there were fewer macrophages in animals of the 8th compared to other days and greater amount of necrosis on day 8 than on day 22. In the copaiba group, the number of gigantocytes increased compared to the days analyzed. CONCLUSION: Copaiba oil showed an improvement in the inflammatory response accelerating its beginning; however, did not affect the amount of abdominal adhesions or collagen fibers.

Co-encapsulation of imiquimod and copaiba oil in novel nanostructured systems: promising formulations against skin carcinoma.

In this study, two types of cutaneous-directed nanoparticles are proposed for the co-encapsulation of imiquimod (a drug approved for the treatment of basal cell carcinoma) and copaiba oil (oil that exhibits anti-proliferative properties). Nanostructured copaiba capsules (NCCImq) were prepared using the interfacial deposition method, and nanostructured Brazilian lipids (NBLImq) were prepared by high-pressure homogenization. The formulations exhibited average diameter, zeta potential, pH and drug content of approximately 200nm, -12mV, 6 and 1mgmL(-1), respectively. In addition, the formulations exhibited homogeneity regarding particle size, high encapsulation efficiency and stability. Both nanocarriers controlled imiquimod release, and NBLImq exhibited slower drug release (p < 0.05), likely due to increased interaction of the drug with the solid lipid (cupuaçu seed butter). The in vitro evaluation of the imiquimod-loaded nanocarriers was performed using healthy skin cells (keratinocytes, HaCaT); no alteration was observed, suggesting the biocompatibility of the nanocarriers. In addition, in vitro skin permeation/penetration using pig skin was performed, and NCCImq led to increased drug retention in the skin layers and reduced amounts of drug found in the receiver solution. Thus, NCCImq is considered the most promising nanoformulation for the treatment of skin carcinoma.

Racional:A utilização de telas nas herniorrafias foi grande revolução na área cirúrgica; contudo, elas trouxeram algumas dificuldades, como grande área de fibrose, maior dor pós-operatória e risco de infecção. A busca por novas substâncias que minimizem esses efeitos deve ser estimulada. As plantas medicinais se destacam por apresentaram conjunto de princípios ativos que podem atuar em todos esses problemas.Objetivo:Verificar se o óleo de copaíba influência no reparo de defeitos abdominais em ratos corrigidos com tela de Vicryl®.Método:Vinte e quatro ratas Wistar foram submetidas a um defeito abdominal e corrigidos com tela de Vicryl®. Elas foram distribuídas em dois grupos: controle e copaíba via gavagem, administrada durante sete dias após a operação. A análise dos animais ocorreu nos dias 8, 15 e 22 de pós-operatório. Foi analisada a quantidade de aderências e feita análise microscópica da tela.Resultados:Não houve diferença estatística em relação à quantidade de aderências. Todos os animais tiveram sinais de inflamação aguda. No grupo controle, houve menor quantidade de macrófagos nos animais do dia 8 em relação aos demais dias e maior quantidade de necrose no dia 8 do que no dia 22. No grupo copaíba, o número de gigantócitos aumentou em relação aos dias analisados.Conclusão:O óleo de copaíba mostrou melhora na resposta inflamatória acelerando o seu início; contudo, não interferiu na quantidade de aderências abdominais ou fibras colágenas.

Copaiba oil effect under different pathways in mice subjected to sepsis.

PURPOSE: To evaluate the effects of copaiba oil administered by different routes on survival of mices subjected to cecal ligation and puncture. METHODS: Thirty two mice were distributed into four study groups (N=8): Sham group: normal standard animals; CONTROL GROUP: submitted a cecal ligation and puncture (CLP); Gavage group: submitted a CLP, and treat with copaiba oil by gavage; and Subcutaneous group: submitted a CLP, and treat with copaiba oil by subcutaneous injection. After the death of the histological analysis were performed. The Kaplan-Meier curves of surviving time were realized. RESULTS: All animals that received copaiba, regardless of the route used, survived longer when compared to the control group (p<0.0001), whereas the survival time ranged from 20 hours for the control group up to 32 hours for the animals of gavage group and 52 for subcutaneous group. The animals that received gavage copaiba lived about and about 20 hours unless the subcutaneous group (p=0.0042). There was no statistical difference when compared the intensity of inflammatory response (p>0.05) CONCLUSION: Prophylactic subcutaneous administration of copaiba in mice subjected to severe sepsis by cecal ligation and puncture, resulted in a survival time higher than non-use or use of this oil by gavage.

"No doubt this childhood disease on Vestmannö can be prevented"--neonatal tetanus on the Westman Islands.

At the beginning of the 1800 s neonatal tetanus was a major health hazard on the Westman Islands, an archipelago immediately south of Iceland. Up to 60­70% of newborn babies died in the course of the first two weeks of life, and Danish health authorities were almost helpless in the face of this mysterious disease. In 1847 the young Danish doctor Peter Anton Schleisner (1818-1900) was sent to the islands to investigate the conditions there. He established a maternity hospital, gave advice on hygiene and encouraged breast-feeding and a number of changes in diet. Since there was no known treatment, Schleisner's only option was to resort to preventive measures. He dressed the umbilical stump with balsamum copaivae and tried well-established methods such as opium tincture with saffron and mercurial ointment if there was any sign of infection. By the time he returned to Denmark after nine months, mortality had been halved. Neonatal mortality on the Westman Islands remained at the same low level throughout the rest of the 19th century. According to popular belief this was due to the naflaolian (navel oil) which Schleisner introduced. Nevertheless, it can be partly attributed to generally improved living standards, a relatively higher number of mothers in better social circumstances, a greater urban influence, changed lifestyle and hygienic measures. Schleisner's efforts are considered to have had major significance when conditions are compared with those on the Scottish island of St Kilda where the situation was the same and improved only just before the turn of the century.

Acoustic pressure wound therapy in the treatment of stage II pressure ulcers.

Pressure ulcers are localized skin injuries secondary to unrelieved pressure or friction. Patients with immobility issues are at increased risk for developing pressure ulcers. In 2004, stricter federal regulations for prevention and treatment of pressure ulcers in institutional settings--eg, long-term care facilities--were introduced. Effective, low-cost treatments for pressure ulcers are needed; acoustic pressure wound therapy (APWT), a noncontact, low-frequency, therapeutic ultrasound system, is one option. A retrospective case series of six long-term care patients (two men and one woman, age range 61 to 92 years), each with one Stage II pressure ulcer, is presented. Acoustic pressure wound therapy was provided as an adjunct to standard treatment that included balsam of Peru/castor oil/trypsin ointment, hydrogel, hydrocolloid dressings, silver dressings, and offloading. Outcomes (days to healing) were determined through changes in wound dimensions. Study participants each received APWT for 3 to 4 minutes three to four times weekly. In four of the six wounds, the average number of days to healing was 22. One of the two remaining patients discontinued treatment at 95% healed; treatment for the sixth patient was ongoing due to hospitalization that delayed APWT. In a long-term care setting, APWT added to standard of care may accelerate healing of Stage II pressure ulcers.

Chemical composition and anti-inflammatory activity of copaiba oils from Copaifera cearensis Huber ex Ducke, Copaifera reticulata Ducke and Copaifera multijuga Hayne--a comparative study.

Copaiba oil is an oleoresin obtained from the Copaifera L. genus (Leguminoseae) commonly featured in anti-inflammatory recipe prescribed by Amazonian traditional medical practitioners and featured in Europe and North America pharmacopeias of the past. Chemical and anti-inflammatory activity investigations from the copaiba oils obtained from Copaifera multijuga Hayne, Copaifera cearensis Huber ex Ducke and Copaifera reticulata Ducke species have proved that, although similar, these oleoresins possess varied composition and anti-inflammatory activity. Chromatographic studies showed that the main compound among sesquiterpenes was beta-caryophyllene (57.5, 19.7 and 40.9%, respectively), followed by alpha-humulene, alpha-copaene, alpha-bergamotene, delta-cadinene, with different amounts in each oleoresin. Among the diterpenes, copalic acid was the main component from Copaifera multijuga Hayne (6.2%) and was found in all the oleoresins studied. In Copaifera cearensis Huber ex Ducke, clorechinic (11.3%) and hardwickiic acids (6.2%) were the major diterpenes while kaurenoic (3.9%) and kolavenic acids (3.4%) predominated in Copaifera reticulata Ducke. The pharmacologic effects of the three oleoresins were evaluated in vitro by measuring the NO production by murine macrophages and in vivo using the zymosan induced pleurisy model in mice. The Copaiba Oil from Copaifera multijuga Hayne (100 mg/kg) was the most potent, inhibiting both NO production and the pleurisy induced by zymosan. The oleoresins from Copaifera cearensis Huber ex Ducke and Copaifera reticulata Ducke were also able to inhibit NO production and the pleurisy but with less intensity.

Managing a traumatic wound in a geriatric patient.

Clinical management of a wound in a geriatric patient requires an understanding of age-related changes in the skin and the knowledge to make appropriate treatment choices. This case study describes clinical assessment and management of a traumatic hip wound in a 75-year-old patient. In addition to addressing his nutritional status by providing supplements, topical wound care preparations, including papain-urea and castor oil/balsam of Peru/trypsin, were used as a conservative approach to address debridement and periwound skin concerns. Extra vigilance is required to assess wounds in geriatric patients to determine proper wound treatment and achieve optimum results. Additional studies to evaluate optimal treatment strategies in the clinical management of traumatic wounds in the geriatric population are needed.

Heparin-induced thrombocytopenia syndrome bullous lesions treated with trypsin-balsam of peru-castor oil ointment: a case study.

Heparin-induced thrombocytopenia syndrome is a serious, potentially life-threatening adverse reaction to the use of heparin anticoagulation therapy that can result in significant skin damage and organ morbidity. A case study design is used to describe the innovative use of a topical wound treatment (trypsin-balsam of Peru-castor oil ointment) on bullous lesions related to the effects of this syndrome. An elderly, morbidly obese woman was treated for 2 weeks with twice-daily applications of the product along with non-adherent oil emulsion dressings. Oozing decreased substantially within a few days and open blisters closed within 1 week. After 2 weeks of therapy, the bullous skin reaction was fully resolved with no recurrence. The results of this case study suggest that this topical product may have had a positive effect on the bullous lesions and should be considered for use in other similar significant integumentary reactions.

Comparison of pressure ulcer treatments in long-term care facilities: clinical outcomes and impact on cost.

This study compared clinical outcomes and nursing labor costs associated with (a) balsam Peru, hydrogenated castor oil, and trypsin (BCT) ointment; (b) BCT + Other; and (c) Other treatments in 2014 wound episodes occurring in 861 patients (mean 2.34 wounds/patient). Treatment with BCT ointment or BCT + Other was associated with a higher healing rate (P < .05). No Stage 1 or 2 ulcer treated with BCT ointment progressed, compared with 13.8% treated with BCT + Other and 13.4% treated with Other. The reported mean duration of treatment and time to heal were shorter for ulcers treated with BCT ointment, but differences did not reach significance, possibly because of the variability in reported treatment times. Mean daily nursing labor costs were lower for treatment with BCT than Other ($50.8 vs $61.7, P < .05). These data suggest that treatment of Stage 1 or 2 ulcers with BCT may be associated with shorter treatment time and time to heal and a potential reduction in treatment-related nursing labor costs.
