RESUMO
OBJECTIVE: To observe the efficacy of a plant-derived wound dressing (1 Primary Wound Dressing®), a mixture of hypericum and neem oil, in different types of paediatric burns. METHOD: A retrospective review was conducted over the complete healing course of 9 paediatric patients with a mean age of 8.17±3.35 (1-11 years), presenting mixed, partial or full-thickness burns. The treatment applied by the wound care specialist consisted of daily cleansing of the wound with a saline solution and application of 1 Primary Wound Dressing on the whole wound surface. There was no application of a secondary dressing. The time to heal, wound size, ease of handling, pain and complications were recorded. Procedural and background pain were observed in six of the patients older than 5 years (mean age 9.6±2.39, range 8-11 years). Due to the small number of patients examined during the period studied, it was not possible to perform statistical analyses. RESULTS: The mean wound size was 50.76±48.32cm2 (4.63-132.0cm2). A rapid induction of granulation tissue and re-epithelialisation was observed. Time to complete healing was 16.6±4.69 days (10-22 days). No complications related to wound infection was observed. The 6 patients older than five years reported a strong relief of pain, from an initial value of 7-8 out of 10 to 0 out of 10 within the first week of treatment. This remained at the 0 out of 10 level during the second and third weeks of treatment. CONCLUSION: This retrospective, non-controlled examination suggests that 1 Primary Wound Dressing could be an effective therapy for the treatment of burn wounds, with benefits including pain reduction and simplicity of use. Further evaluations with a larger population are required to document the effectiveness of this plant-derived wound dressing in a controlled fashion. DECLARATION OF INTEREST: There were no external sources of funding for this study. F. Carnevali is a researcher and co-inventor of 1 Primary Wound Dressing®.

METHODS: We analyzed the potential influence that associated risk factors (ARF), such as smoking, alcoholism, overweight, and hypertension, could have on the establishment of chronic chagasic cardiomyopathy (CC). The sample was comprised of 124 individuals, 69 males and 55 females (mean age +/- SD, 41 +/- 9.5 years), who were born in en demic areas of Northern Argentina and migrated further to Rosario City, an area where autochthonous cases of Chagas' disease have never been registered. Assessments included the following: clinical examination to discard previous cardiomyopathies; search for the presence of ARF according to standard criteria; specific serology; frontal chest X-ray, and 12-lead resting electrocardiogram (ECG). Subjects were classified on the basis of their serological status and presence of ARF into four groups: Tc+ARF+ T. cruzi-infected persons with ARF (n = 41); Tc-ARF+ seronegativity in presence of ARF (n = 27); Tc+ARF- individuals showing positive serology that lacked ARF (n = 27), and Tc-ARF- seronegative individuals having no ARF (n = 29). RESULTS: Except for a higher female/male ratio in groups presenting no ARF (p < 0.02), no statistical differences as to age, length of residence in endemicity areas (LR), and ARF distribution were recorded among groups. Forty-one persons presented abnormal ECG tracings, distributed thus: Tc+ARF+, 18/41; Tc-ARF+, 14/27, Tc+ARF-, 14/27, and Tc-ARF, 4/29 (p < 0.01, in relation to the latter group). Subjects from the Tc+ARF+, Tc-ARF+, and Tc+ARF- groups had 4.89-, 6.7-, and 6.7-fold increases, respectively, if having an abnormal ECG when compared with Tc-ARF- individuals. Comparisons on the frequency of abnormal ECG between seropositives carrying ARF or not yielded a non-significant odds ratio, be it estimated as crude, or after adjusting for sex, age, and LR in multivariate analysis. CONCLUSIONS: Presence of ARF was not associated with an increasing risk of cardiac affectation in chronically T. cruzi-infected persons, but resulted in chagasic-compatible ECG abnormalities in those seronegative individuals.
