Effectiveness of Acupuncture as Auxiliary Treatment for Chronic Headache.

Objectives: To assess the effectiveness of acupuncture as an auxiliary analgesic treatment for chronic headaches and the influence of this treatment on the quality of life, as the effectiveness of acupuncture in chronic headache is still controversial.

Methods: Thirty-four patients selected from a University Hospital Clinic on Chronic Pain were divided into two groups: True acupuncture (Group 1), in which the recommended points of the Traditional Chinese Medicine were used for each type of headache and sham acupuncture (Group 2), in which the needles were inserted into a device (the stick-on moxa), at the same points as Group 1. Both groups used the prescribed preventive medication for pain.

Bio-based synthesis of silver nanoparticles from orange waste: effects of distinct biomolecule coatings on size, morphology, and antimicrobial activity.

Purpose: Despite the numerous reports on biological syntheses of silver nanoparticles (AgNPs), little is known about the composition of their capping agents, protein corona of plant extract-mediated synthesis, and their influence on the properties of AgNPs. Here, orange () waste was utilized as a source of an extract for AgNP synthesis (the protein corona composition of which was elucidated), and also as a starting material for hesperidin and nanocellulose extraction, which were used for bio-based AgNP synthesis. A comparison of the results using the two methods of synthesis is presented.

Histopathological and immunohistochemical aspects of American cutaneous leishmaniasis before and after different treatments.

Background: The histopathology and immune responses of the healing process of leishmaniasis are still poorly studied.

Objectives: This study aimed to examine the histopathological and immunological aspects of lesions of patients with cutaneous leishmaniasis before and after different therapeutic methods.

Methods: We studied 23 individuals grouped according to the treatments: Glucantime, Glucantime + Leishvacin and Glucantime + Leishvacin associated with Bacillus Calmette-Guerin.

Cluster randomised trial to evaluate the effectiveness of a vaccine against cutaneous leishmaniasis in the Caratinga microregion, south-east Brazil.

Background: The eco-epidemiological complexity of American cutaneous leishmaniasis (ACL) has made it difficult to devise an efficient strategy for management of the disease, and development of an effective vaccine remains the most promising approach. The objective of the study was to determine the reduction in incidence of ACL following intramuscular administration of two doses of a killed Leishmania (Leishmania) amazonensis vaccine.

Methods: A cluster randomised trial was conducted from 2002 to 2011 in 108 localities in an endemic area of southeast Brazil.

Distinct pattern of immunophenotypic features of innate and adaptive immunity as a putative signature of clinical and laboratorial status of patients with localized cutaneous leishmaniasis.

In this study, we have analysed the phenotypic features of innate/adaptive immunity of patients with localized cutaneous leishmaniasis (LCL), categorized according to their clinical/laboratorial status, including number of lesion (L1; L2–4), days of illness duration (≤60;>60) and positivity in the Montenegro skin test (MT−;MT+). Our findings highlighted a range of phenotypic features observed in patients with LCL (↑%HLA-DR+ neutrophils; ↑CD8+ HLA-DR+/CD4+ HLA-DR+ T cell ratio; ↑HLA-DR in B lymphocytes, ↑%CD23+ neutrophils, monocytes and B cells; ↑α-Leishmania IgG and ↑serum NO₂⁻ + NO₃⁻). Selective changes were observed in L1 (↑%HLA-DR+ neutrophils, ↑CD8+ HLA-DR+/CD4+ HLA-DR+ T cell ratio and ↑serum NO₂⁻ + NO₃⁻) as compared to L2–4 (↑%CD5− B cells; ↑CD23+ B cells and ↑α-Leishmania IgG).
