The objective of this study was to determine if matrix metalloproteinase-7 (MMP-7) expression is related to human papilloma virus (HPV) status, clinical parameters, and outcome in oropharyngeal squamous cell carcinoma (OPSCC). Tumor tissue specimens from 201 OPSCC patients treated with curative intent were available for immunohistochemistry, and the samples were stained with monoclonal MMP-7 antibody. All the patients were followed up at least 3 years or until death. MMP-7 expression did not differ between HPV-positive and HPV-negative patients...

Expression of regenerating islet-derived protein 4 (REG4), a secretory protein involved in cell differentiation and proliferation, is upregulated in inflammatory bowel diseases and in many gastrointestinal malignancies. The prognostic significance of its expression in pancreatic ductal adenocarcinoma is unknown. Our aim was to investigate tumor tissue and serum REG4 expression in pancreatic ductal adenocarcinoma patients. We also evaluated as a control the diagnostic value of serum REG4 level in patients with chronic pancreatitis...

Gastric cancer is the second most common cause of cancer-related mortality worldwide. Accurate prediction of disease progression is difficult, and new biomarkers for clinical use are essential. Recently, we reported that the proteasome-associated deubiquitinating enzyme UCHL5/Uch37 is a new prognostic marker in both rectal cancer and pancreatic ductal adenocarcinoma. Here, we have assessed by immunohistochemistry UCHL5 tumor expression in gastric cancer. The study cohort comprised 650 patients, who underwent surgery in Helsinki University Hospital, Finland, between 1983 and 2009...

AIMS: Oral tongue squamous cell carcinoma (OTSCC) has a relatively poor outcome, and there is a need to identify better prognostic factors. Recently, tumour-stroma ratio (TSR) has been associated with prognosis in several cancers. The aim of this multi-institutional study was to evaluate the prognostic value of TSR from original haematoxylin and eosin (HE)-stained tumour-resection slides in a series of early-stage (cT1-2N0) OTSCC patients. METHODS AND RESULTS: A TSR cutoff value of 50% was used to divide the patients into stroma-rich (≥50%) and stroma-poor (<50%) groups...

We describe two contrasting patients with multiple cerebral aneurysms and a previous history of resected cardiac myxomas with no cardiac recurrence on follow-up echocardiography. Both patients presented with stroke- like symptoms; one with a left visual defect and the other with right hemiplegia. Magnetic resonance imaging of the brain of both patients showed the presence of multiple cerebral aneurysms that was later confirmed on conventional angiography. Both patients' aneurysms were managed conservatively...

The differential diagnosis of heel pain is extensive, but a mechanical etiology is the most common. The specific anatomic location of the pain can help guide diagnosis. The most common diagnosis is plantar fasciitis, which leads to medial plantar heel pain, especially with the first weight-bearing steps after rest. Other causes of plantar heel pain include calcaneal stress fractures (progressively worsening pain after an increase in activity or change to a harder walking surface), nerve entrapment or neuroma (pain accompanied by burning, tingling, or numbness), heel pad syndrome (deep, bruise-like pain in the middle of the heel), and plantar warts...

Toll-like receptors (TLR) are activated by endogenous alarmins such as fragmented extracellular matrix compounds found in the degenerating disc. TLRs regulate cytokine, neurotrophin, and protease expression in human disc cells in vitro, and thus control key factors in disc degeneration. However, whether TLR activation leads to degenerative changes in intact human discs is unclear. Nucleus pulposus (NP) cells isolated from non-degenerating discs increase IL-1β and nerve growth factor gene expression following treatment with Pam2CSK4 (TLR2/6 agonist) but not Pam3CSK4 (TLR1/2 agonist)...

BACKGROUND: Periodontal pathogens have been linked to oral and gastrointestinal (orodigestive) carcinogenesis. However, the exact mechanisms remain unknown. Treponema denticola (Td) is associated with severe periodontitis, a chronic inflammatory disease leading to tooth loss. The anaerobic spirochete Td is an invasive bacteria due to its major virulence factor chymotrypsin-like proteinase. Here we aimed to investigate the presence of Td chymotrypsin-like proteinase (Td-CTLP) in major orodigestive tumours and to elucidate potential mechanisms for Td to contribute to carcinogenesis...
