The aim of this study was to determine the utility of the epithelial-mesenchymal transition (EMT) transcription factors Twist and Snai1 in the treatment of naïve prostate cancer.

HBHA-IGRA and cytotoxic mediators release assays for the diagnosis of cervical tuberculous lymphadenitis.

Cervical tuberculous lymphadenitis (CTL), the most frequent extrapulmonary form of tuberculosis, is currently a major health problem in Tunisia and in several regions around the world. CTL diagnosis is challenging mainly due to the paucibacillary nature of the disease and the potential misdiagnosis as cervical non-tuberculous lymphadenitis. This study demonstrates the added value of the heparin-binding hemagglutinin-interferon-gamma release assay as an immunoassay in the context of CTL.

Correlation between E-cadherin/β-catenin, Vimentin expression, clinicopathologic features and drug resistance prediction in naïve prostate cancer: A molecular and clinical study.

Although epithelial-mesenchymal markers play an important role in prostate cancer (PC), further research is needed to better understand their utility in diagnosis, cancer progression prevention, and treatment resistance prediction. Our study included 111 PC patients who underwent transurethral resection, as well as 16 healthy controls. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to examine the expression of E-cadherin, β-catenin, and Vimentin.

Pathologic complete response to neoadjuvant imatinib of a gastric stromal tumor with concomitant mutations in : A case report and literature review.

Key Clinical Message: We report the first case of pathologic complete response (pCR) to neoadjuvant imatinib in a gastric stromal tumor harboring mutations in both exons 11 and 9. The significance of this co-occurrence is unknown and might increase the responsiveness of gastrointestinal stromal tumors (GISTs) to imatinib.

Abstract: pCR of GIST to neoadjuvant imatinib is rare.

Fatal cerebral sinus thrombosis associated with diabetic ketoacidosis in a child.

Cerebral sinus thrombosis (CST) is an uncommon condition in children with a variable clinical presentation which has rarely been described in the setting of diabetic ketoacidosis. We present the case of 14-year-old child in whom lateral sinus thrombosis was caused by dehydration complicating ketoacidosis in a previously undiagnosed type 1 diabetes. The diagnosis of the CST was established during the autopsy due to the rapidity of the neurological deterioration.
