Anti-inflammatory and analgesic evaluation of hydroalcoholic extract and fractions from seeds of Piper cubeba L. (Piperaceae)

Some of the Piper species have been applied for the treatment of several diseases (anti-oxidant, antimicrobial, anti-inflammatory, and analgesic), considering multiple applications used in traditional medicine of different countries. About these, the present study evaluated some biological activities of Piper cubeba, as writhing test induced by acetic acid, ear edema induced by croton oil and paw edema induced by carrageenan were used by evaluated the analgesic and anti-inflammatory activities of crude hydroalcoholic extract (PCE) and its fractions of different polarities of P. cubeba L. seeds. The lethal dose (LD50) and the effective dose (ED50) were evaluated too. Both the PCE and dichloromethane fraction showed decrease values of edema and abdominal constrictions. The results obtained in this study confirm the low toxicity and analgesic and anti-inflammatory activities of PCE from P. cubeba seeds, justifying its use in folk medicine.

Evaluation of antinociceptive and antiinflammatory effects of Croton pullei var. glabrior Lanj. (Euphorbiaceae)

Croton pullei var. glabrior Lanj. (Euphorbiaceae) é uma liana, amplamente distribuída na Floresta Amazônica. Na medicina popular, diversas plantas do gênero Croton têm sido utilizadas com fins terapêuticos em patologias que envolvem dor e inflamação, o que justifica este trabalho. O objetivo deste estudo foi investigar as atividades antinociceptiva e do extrato metanólico das folhas de C. pullei (MECP). O MECP reduziu, de forma dose-dependente, o número de contorções abdominais (1,2 %) em camundongos, sugerindo uma atividade antinociceptiva da planta. Por outro lado, o MECP não alterou significativamente a reatividade ao estímulo térmico no teste da placa quente e a reatividade à estimulação química na primeira fase do teste da formalina, indicando um mecanismo não-opioidérgico. O MECP reduziu a nocicepção na segunda fase do teste da formalina, inibiu o edema de orelha induzido pelo óleo de croton e reduziu a migração leucocitária no teste da peritonite induzida por carragenina, indicando uma atividade antiinflamatória. Apesar dos mecanismos responsáveis pelos efeitos da planta ainda não estarem completamente esclarecidos, estes resultados parecem justificar o uso medicinal potencial de Croton pullei var. glabrior Lanj. em patologias que envolvam dor e inflamação.

Evaluation of the therapeutic response of hepatitis C in coinfected patients (HIV/HCV): a study of cases from a hospital for chronic liver diseases in the Eastern Brazilian Amazon

INTRODUCTION: The aim of this study was to evaluate the therapeutic response of hepatitis C in patients coinfected with human immunodeficiency virus (HIV-1). METHODS: A retrospective study of 20 patients coinfected with HIV-1/HCV who were treated in the outpatient liver clinic at the Sacred House of Mercy Foundation Hospital of Pará (Fundação Santa Casa de Misericórdia do Pará - FSCMPA) from April 2004 to June 2009. Patients were treated with 180µg PEG interferon-α2a in combination with ribavirin (1,000 to 1,250mg/day) for 48 weeks. The end point was the sustained virological response (SVR) rate (HCV RNA negative 24 weeks after completing treatment). RESULTS: The mean age of the patients was 40±9.5 years, of which 89% (n=17) were male, and the HCV genotypes were genotype 1 (55%, n=11/20), genotype 2 (10%, n=2/20) and genotype 3 (35%, n=7/20). The mean CD4+ lymphocyte count was 507.8, and the liver fibrosis stages were (METAVIR) F1 (25%), F2 (55%), F3 (10%) and F4 (10%). The early virological response (EVR) was 60%, the end-of-treatment virological response (EOTVR) was 45% and the SVR was 45%. CONCLUSIONS: The median HCV viral load was high, and in 85% of cases in which highly active antiretroviral therapy (HAART) was used, none of the patients with F3-F4 fibrosis responded to treatment. Of the twenty patients treated, 45% achieved SVR and 45% achieved EOTVR. Studies that include cases from a wider region are needed to better evaluate these findings.

Prevalence of Oral Lesions in Hospitalized Patients with Infectious Diseases in Northern Brazil

The aim of this study was to assess the prevalence of oral lesions in infectious-contagious diseases patients being treated in the University Hospital of the Federal University of Para, northern Brazil. One hundred seven patients with infectious diseases were clinically investigated for oral lesions at the University Hospital of Para, northern Brazil. From total sample, most patients were men (65.7%) with a mean age of 45.4 years. About prevalence of systemic diseases, tuberculosis was the most frequent illness, followed by AIDS, hepatitis types B and C, leishmaniasis, and meningitis. Analyzing oral manifestations, periodontal diseases and candidiasis were the most prevalent diseases in both genders, followed by recurrent aphthous ulcers, saburral tongue, simplex herpes, and squamous cell carcinoma. Of all 107 patients, only 10 males and 6 females did not present any oral manifestation. There was no statistical difference between genders with any systemic condition (P > 0.05). The great prevalence of oral manifestations in hospitalized patients with systemic disorder emphasizes the need of integral dental care in this context, aiming at a multidisciplinary approach of patients. Therefore, presence of some oral conditions, such as candidiasis, should be an alert to different systemic conditions, once in assistance with physicians; dentists can influence the early diagnosis and treatment.

Health related quality of life measure in systemic pediatric rheumatic diseases and its translation to different languages: an international collaboration

Background: Rheumatic diseases in children are associated with significant morbidity and poor health-related quality of life (HRQOL). There is no health-related quality of life (HRQOL) scale available specifically for children with less common rheumatic diseases. These diseases share several features with systemic lupus erythematosus (SLE) such as their chronic episodic nature, multi-systemic involvement, and the need for immunosuppressive medications. HRQOL scale developed for pediatric SLE will likely be applicable to children with systemic inflammatory diseases.Findings: We adapted Simple Measure of Impact of Lupus Erythematosus in Youngsters (SMILEY (c)) to Simple Measure of Impact of Illness in Youngsters (SMILY (c)-Illness) and had it reviewed by pediatric rheumatologists for its appropriateness and cultural suitability. We tested SMILY (c)-Illness in patients with inflammatory rheumatic diseases and then translated it into 28 languages. Nineteen children (79% female, n= 15) and 17 parents participated. The mean age was 12 +/- 4 years, with median disease duration of 21 months (1-172 months). We translated SMILY (c)-Illness into the following 28 languages: Danish, Dutch, French (France), English (UK), German (Germany), German (Austria), German (Switzerland), Hebrew, Italian, Portuguese (Brazil), Slovene, Spanish (USA and Puerto Rico), Spanish (Spain), Spanish (Argentina), Spanish (Mexico), Spanish (Venezuela), Turkish, Afrikaans, Arabic (Saudi Arabia), Arabic (Egypt), Czech, Greek, Hindi, Hungarian, Japanese, Romanian, Serbian and Xhosa.Conclusion: SMILY (c)-Illness is a brief, easy to administer and score HRQOL scale for children with systemic rheumatic diseases. It is suitable for use across different age groups and literacy levels. SMILY (c)-Illness with its available translations may be used as useful adjuncts to clinical practice and research.
