Disseminated Cutaneous Leishmaniasis and Alcohol Misuse, Northeast Brazil, 2015-2018.

Disseminated cutaneous leishmaniasis (DCL) is an uncommon form of Leishmania braziliensis infection. It remains unknown why some people develop this clinical condition. We describe 14 DCL patients in Northeast Brazil during 2015-2018.

Postmortem Findings for 7 Neonates with Congenital Zika Virus Infection.

Postmortem examination of 7 neonates with congenital Zika virus infection in Brazil revealed microcephaly, ventriculomegaly, dystrophic calcifications, and severe cortical neuronal depletion in all and arthrogryposis in 6. Other findings were leptomeningeal and brain parenchymal inflammation and pulmonary hypoplasia and lymphocytic infiltration in liver and lungs. Findings confirmed virus neurotropism and multiple organ infection.

Structural characteristics are crucial to the benefits of guar gum in experimental osteoarthritis.

Protein-free guar gum (DGG) was oxidized (DGGOX) or sulfated (DGGSU) by insertion of new groups in C-6 (manose) and C-6 (galactose), for DGGOX and DGGSU, respectively. Rats were subjected to anterior cruciate ligament transection (ACLT) of the knee, joint pain recorded using the articular incapacitation test, and the analgesic effect of intraarticular 100μg DGG, DGGOX or DGGSU solutions at days 4-7 was evaluated. Other groups received DGG or saline weekly, from days 7 to 70 and joint damage assessed using histology and biochemistry as the chondroitin sulfate (CS) content of cartilage.

Press imprint smear: a rapid, simple, and cheap method for the diagnosis of cutaneous leishmaniasis caused by Leishmania (Viannia) braziliensis.

A modified imprint method, Press-Imprint-Smear, was compared with histopathology for the diagnosis of cutaneous leishmaniasis. Amastigotes were seen in 69 (92%) of 75 individuals in one or both assays. The Press-Imprint-Smear was positive in 85.

Distinct cellular migration induced by Leishmania infantum chagasi and saliva from Lutzomyia longipalpis in a hemorrhagic pool model.

Recruitment of a specific cell population after Leishmania infection can influence the outcome of the disease. Cellular migration in response to Leishmania or vector saliva has been reported in air pouch model, however, cellular migration induced by Leishmania associated with host's blood and vector saliva in this model has not been described. Herein we investigated cellular migration into air pouch of hamster after stimulation with combination of L.

The utility of p16 INK4a and Ki-67 to identify high-grade squamous intraepithelial lesion in adolescents and young women.

Background: The repair of the immature squamous epithelium following HPV infection may mimic HSIL in adolescent women.

Aim: to study the utility of p16 INK4a and Ki-67 in diagnosis of cervical squamous lesions in adolescents and young adults.

Materials And Methods: In a cross-sectional study, the evaluation of p16 INK4a and Ki-67 immunohistochemistry was performed on 72 cervical biopsies of adolescents and young adults women diagnosed as negative for malignancy and intraepithelial lesion (NML) (n = 18) or positive for low grade (LSIL) (n = 31) and high grade (HSIL) (n = 23) squamous intraepithelial lesions in two references services in Fortaleza-Brazil.

High-dose oral fluconazole therapy effective for cutaneous leishmaniasis due to Leishmania (Vianna) braziliensis.

We report for the first time the successful use of fluconazole to treat cutaneous leishmaniasis due to Leishmania braziliensis. We used escalating doses from 5 to 8 mg/kg per day. At a dose of 5 mg/kg per day, 75% patients were cured, and at 8 mg/kg per day, the cure rate was 100%.

In vitro initial immune response against Leishmania amazonensis infection is characterized by an increased production of IL-10 and IL-13.

The initial encounter of Leishmania with its host's immune system is important in the outcome of infection. Previous studies have shown that PBMCs from healthy volunteers (HV) exposed to Leishmania differ in IFN-γ production. We have expanded such observations evaluating the profile and kinetics of cytokines (IFN-γ, IL-12p70, IL-10, IL-13), chemokines (CCL5, CCL3, CCL4, CXCL10), and chemokine receptors (CCR1,CCR5, CXCR3, CCR4) in vitro L.

Combined glucosamine and chondroitin sulfate provides functional and structural benefit in the anterior cruciate ligament transection model.

Evidence that combined glucosamine sulfate and chondroitin sulfate (Gluchon) or isolated glucosamine (Glu) modifies joint damage in osteoarthritis (OA) is still lacking. We studied joint pain and cartilage damage using the anterior cruciate ligament transection (ACLT) model. Wistar rats were subjected to ACLT of the right knee (OA) or sham operation.

Protective effect of an extract from Ascaris suum in experimental arthritis models.

We investigated the effect of an extract from a helminth (Ascaris suum) in zymosan-induced arthritis (ZYA) or collagen-induced arthritis (CIA). Rats and mice, respectively, received 1 mg and 0.1 mg zymosan intra-articularly (i.
