Translation and linguistic validation of the EORTC QLQ-PAN26 questionnaire for assessment of health-related quality of life in patients with pancreatic cancer and chronic pancreatitis into isiXhosa and Afrikaans.

Background: Health-related quality of life (HRQOL) parameters have become important components in the holistic management of pancreatic ductal adenocarcinoma (PDAC) and are now increasingly incorporated in treatment protocols. The European Organisation for Research and Treatment of Cancer (EORTC) pancreatic cancer specific questionnaire (QLQ-PAN26) has also been validated for chronic pancreatitis (CP). The objective was to translate the EORTC QLQPAN26 questionnaire into and validate it for isiXhosa and Afrikaans.

Deletion of Interleukin-4 Receptor Alpha-Responsive Keratinocytes in BALB/c Mice Does Not Alter Susceptibility to Cutaneous Leishmaniasis.

The skin microenvironment at the site of infection plays a role in the early events that determine protective T helper 1/type 1 immune responses during cutaneous leishmaniasis (CL) infection. During CL in nonhealing BALB/c mice, early interleukin-4 (IL-4) can instruct dendritic cells for protective Th1 immunity. Additionally, keratinocytes, which are the principal cell type in the skin epidermis, have been shown to secrete IL-4 early after infection.
