Synergistic effect between amoxicillin and TLR ligands on dendritic cells from amoxicillin-delayed allergic patients.
2013
Journal Article; Amoxicillin, a low-molecular-weight compound, is able to interact with dendritic cells inducing semi-maturation in vitro. Specific antigens and TLR ligands can synergistically interact with dendritic cells (DC), leading to complete maturation and more efficient T-cell stimulation. The aim of the study was to evaluate the synergistic effect of amoxicillin and the TLR2, 4 and 7/8 agonists (PAM, LPS and R848, respectively) in TLR expression, DC maturation and specific T-cell response in patients with delayed-type hypersensitivity (DTH) reactions to amoxicillin. Monocyte-derived DC from 15 patients with DTH to amoxicillin and 15 controls were cultured with amoxicillin in the pr…
Stimulation of regional lymphatic and blood flow by epicutaneous oxazolone.
2002
The application of the epicutaneous antigen oxazolone results in persistent induration and erythema; however, the relative changes in lymph and blood flow in the inflammatory skin are largely unknown. To define the contribution of lymph and blood flow to the clinical appearance of cutaneous inflammation, we studied the sheep ear after the application of oxazolone. As a model for the study of these changes, the sheep ear had several experimental advantages: 1) a simplified superficial vascular network, 2) defined lymphatic drainage, and 3) an avascular and alymphatic cartilaginous barrier. Lymph flow was continuously monitored by cannulation of the prescapular efferent lymph duct. Blood flo…

Improvement in Lung Cancer Outcomes With Targeted Therapies: An Update for Family Physicians.
2015
Abstract: In the past decade the advent of target therapy has led to a silent revolution in the treatment of lung cancer. Thanks to the specificity of their target, new tailored drugs are able to achieve a larger benefit and lower toxicity and provide better quality of life than cytotoxic drugs in a limited number of patients, selected by molecular profile. Nowadays, the epidermal growth factor receptor tyrosine kinase inhibitors erlotinib and gefitinib, and the anaplastic lymphoma kinase inhibitor crizotinib, are targeted agents approved for treatment of non-small-cell lung cancer. Family physicians play an important role in the treatment, detection, and management of common toxicities and…
Immunohistochemical markers for histopathological diagnosis and differentiation of acute cutaneous graft‐versus‐host disease
2021
Graft-versus-host disease (GvHD) is a major complication following stem-cell or solid-organ transplantation. Accurate diagnosis of cutaneous GvHD is challenging, given that drug eruptions and viral rashes may present with similar clinical/histological manifestations. Specific markers are not available. We performed the histological examination of biopsy samples from acute GvHD (aGvHD; n = 54), Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN; n = 27), maculopapular drug eruption (MDE; n = 26) and healthy controls (n = 26). Samples of aGvHD showed a decrease in Langerhans cells (LC, p = 0.0001) and an increase in macrophages (MΦ, p = 0.0001) compared to healthy skin. Compared to …
Pruritus precipitated by hydroxyethyl starch: a review.
2005
Summary Hydroxyethyl starch (HES) is widely used for fluid management in broad populations of patients, particularly in the surgery and intensive care settings. Pruritus, often manifested as pruritic crises, is increasingly being recognized as a common major adverse effect of HES administration. This iatrogenic form of pruritus is frequently severe and protracted with a serious negative impact on patient quality of life, including sleep disturbance, disruption of daily routine and mental distress. Such pruritus is generally refractory to available therapies and can persist for up to 12–24 months. All currently clinically available HES solutions entail the risk of pruritus, including those o…
