Results: 84% of CQ25 versus 51% of CQ40 patients experienced parasite recrudescence during follow-up (adjusted odds ratio 0.17, 95%CI 0.08-0.38). Cure rates were significantly improved with CQ40, particularly among adults. Fever clearance time, parasite clearance time, and proportions gametocytaemic post-treatment were similar between treatment groups. Second-line CQ40 treatment resulted in higher failure rates than first-line CQ40 treatment. CQ-resistance marker pfcrt 76T was found in all isolates analysed, while pfmdr1 86Y and 184Y were found in 18% and 37% of isolates respectively.
Conclusions: CQ is not suitable
for first-line falciparum treatment in Afghan refugee communities. The extended-dose CQ regimen can overcome 39% of resistant infections that would AZD6738 supplier recrudesce under the standard regimen, but the high failure rate after directly observed treatment demonstrates its use is inappropriate.”
“Objective.
Oral lichenoid disease (OLD) includes a number of chronic inflammatory processes including oral lichen planus (OLP) and oral lichenoid lesions (OLL) with controversial diagnosis and prognosis. Cyclooxygenase-2 (COX-2) is a key enzyme for inflammatory processes and cellular proliferation. Its overexpression in some premalignant chronic inflammatory diseases and malignant neoplasias could point to its potential as a prognostic factor. The aim of this study was to analyze the COX-2 expression in different subtypes of OLD because of its potential to be a marker of altered behavior.
Study design. Forty-four HDAC assay samples from OLD patients were studied (30 females and 14 males) and classified according to their clinical (C1: only papular lesions/C2: papular and other lesions) and histological
features (HT: OLP typical/HC: OLP compatible) according to published criteria. Standard immunohistochemical procedure was performed for COX-2 expression and a comparative and descriptive statistical analyses were performed.
Results. Epithelial COX-2 overexpression was observed in 24 (54.5%) cases (C1: 13 [54.2%]/C2: 11 [45.8%], HT: 9 [37.5%]/HC: 15 [62.5%], P = .032). Inflammatory COX-2 overexpression was observed in 14 (31.8%) cases (C1: 6 [42.9%]/C2: 8 [57.1%], HT: AZD1152 clinical trial 4 [28.6%]/HC: 10 [71.4%], P = .032).
Conclusion. Differences in COX-2 expression in subtypes of OLD may distinguish cases with a higher premalignant potential. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010;110:738-743)”
“Background: Accurate parasitological diagnosis of malaria is essential for targeting treatment where more than one species coexist. In this study, three rapid diagnostic tests (RDTs) (AccessBio CareStart (CSPfPan), CareStart PfPv (CSPfPv) and Standard Diagnostics Bioline (SDBPfPv)) were evaluated for their ability to detect natural Plasmodium vivax infections in a basic clinic setting.
