OBJECTIVE: To report the long-term follow-up of subsolid nodules (SSNs) detected in participants of a prospective low-dose CT lung cancer screening cohort, and to investigate the utility of the PanCan model in stratifying risk in baseline SSNs. METHODS: Participants underwent a baseline scan, two annual incidence scans and further follow-up scans for the detected nodules. All SSNs underwent a minimum of 2 years of follow-up (unless resolved or resected). Risk of malignancy was estimated using the PanCan model; discrimination [area under the receiver-operating characteristic curve (AUC)] and calibration (Hosmer-Lemeshow goodness-of-fit test) were assessed...

BACKGROUND: Journal club has become a signature pedagogy in postgraduate medical education. In this article, social learning theory, through the lens of "communities of practice" (CoP), is applied to elucidate the process of learning in journal club. MATERIALS AND METHODS: The study is a case study of a surgical journal club. Video recordings of 2 journal club sessions were followed by semistructured audio-recorded interviews with a sample of journal club participants...

BACKGROUND: Chronic ulcers affect roughly 60,000 Irish people, at a total cost of €600,000,000, or €10,000 per patient annually. By virtue of their chronicity, these ulcers also contribute a significant burden to tertiary outpatient vascular clinics. OBJECTIVE: We propose utilizing mobile phone technology to decentralise care from tertiary centres to the community, improving efficiency and patient satisfaction, while maintaining patient safety. METHODS: Bespoke mobile software was developed for Apples iPhone 4 platform...

OBJECTIVE: Breast cancer is the cancer most commonly searched for on the internet. Our aim was to assess daily new breast cancer related posting on the internet. METHODS: We analyzed numbers of new daily posts for common cancers for one month and subsequently analyzed content of 1426 breast cancer related posts. We also assessed use of online discussion forums for breast cancer related dialogue. RESULTS: Breast related topics had significantly more posts per day compared to others (mean 66...

BACKGROUND: Diagnosis of breast cancer recurrence can be difficult as a result of the presence of scar tissue in the breast. Magnetic resonance imaging (MRI) may be superior to traditional imaging in diagnosis of recurrence because of its ability to differentiate malignancy from scarring. Current guidelines on investigation of suspected breast cancer recurrence recommend MRI when other investigations have equivocal findings. We performed the first systematic review on this topic. METHODS: Literature search revealed 35 potentially relevant studies; 10 were included in final analysis...

BACKGROUND: Temporal artery biopsy (TAB) is performed during the diagnostic workup for giant cell arteritis (GCA), a vasculitis with the potential to cause irreversible blindness or stroke. However, treatment is often started on clinical grounds, and TAB result frequently does not influence patient management. The aim of this study was to assess the need for TAB in cases of suspected GCA. METHODS: We performed a retrospective review of 185 TABs performed in our institution from 1990 to 2010...

While the overall incidence of pouchitis is low, extensive research continues at clinical and experimental levels in attempts to unravel its etiology. The ileal pouch and pouchitis together represent a unique in vivo opportunity to study mucosal adaptation and inflammation in depth. In the recent past, molecular data relating to pouchitis has significantly expanded. These data provide invaluable insight into intracellular and extracellular events that underpin mucosal adaptation and inflammation. Advances in classification, risk factor evaluation, and prevention have meant that a review of this data, as well as its relationship to our current understanding of pouchitis, is both timely and warranted...

We report here how a heterotopic penetrating peptic ulcer progressed to cause small bowel obstruction in a patient with multiple previous negative investigations. The clinical presentation, radiographic features and pathological findings of this case are described, along with the salient lessons learnt. The added value of wireless capsule endoscopy (WCE) in such circumstances is debated.

REVIEW
Mark Corrigan, Ronan A Cahill, Henry Paul Redmond
Laparoscopic alternatives to conventional surgical procedures confer many advantages to patients including reduced postoperative pain, shortened convalescence and, perhaps, improved disease-related outcomes. The diminished degree of immune dysfunction apparent with these techniques may underpin these beneficial aspects. However, minimal access is accompanied by various ancillary anesthetic and mechanical associations (including the induction of a carbon dioxide pneumoperitoneum), which must be considered in addition to reduced tissue trauma when attempting to correlate cause with effect...

BACKGROUND: Cyclooxygenase-2 enzyme (COX-2) is overexpressed in human non-small cell lung cancer (NSCLC) but is not expressed in small cell lung cancer. Selective COX-2 inhibitors have been shown to induce apoptosis in NSCLC cells, an effect which is associated with the regulation of intracellular MAP kinase (MAPK) signal pathways. Our aims were to characterize the effects of COX-2 inhibition by rofecoxib on apoptosis in human NSCLC and small cell lung cancer cell lines. METHODS: The human NSCLC cell line NCI-H2126 and small cell lung cancer cell line DMS-79 were used...

OBJECTIVE: To outline the emerging significance of Toll-like receptor (TLR) signaling pathways in surgical diseases. DATA SOURCES: A systematic review of the literature was undertaken by searching the MEDLINE database for the period 1966 to 2005 without language restriction. STUDY SELECTION: Original or review articles that described experimental data on the activation of TLR signaling pathways in surgically relevant diseases were selected for inclusion in this review...

Resident host microflora condition and prime the immune system. However, systemic and mucosal immune responses to bacteria may be divergent. Our aim was to compare, in vitro, cytokine production by human mononuclear and dendritic cells (DCs) from mesenteric lymph nodes (MLNs) and peripheral blood mononuclear cells (PBMCs) to defined microbial stimuli. Mononuclear cells and DCs isolated from the MLN (n = 10) and peripheral blood (n = 12) of patients with active colitis were incubated in vitro with the probiotic bacteria Lactobacillus salivarius UCC118 or Bifidobacterium infantis 35624 or the pathogenic organism Salmonella typhimurium UK1...

The discovery of Toll-like receptors has substantially changed our knowledge of pathogen recognition. 11 Toll-like receptors have so far been described in humans. These recognize distinct pathogen associated molecular patterns, as well as endogenous ligands and small molecular synthetic compounds. TLRs have a multifunctional role in pathogen-triggered immune responses and represent an important connection between the "innate" and "adaptive" immunity. The role of the TLRs in the recognition of pathogens renders them a key figure in the activation of the immune response during surgical sepsis...

The pathway involved in Fas-mediated neutrophil apoptosis remains to be fully elucidated. We examined whether this pathway involved either oxygen-dependent or calcium-dependent mechanisms. We also investigated whether taurine, a powerful antioxidant and regulator of intracellular calcium fluxes, could inhibit Fas-mediated neutrophil apoptosis. Neutrophils were stimulated with Fas monoclonal antibody in the presence or absence of taurine. Fas receptor ligation resulted in significant neutrophil apoptosis at 18 h...

BACKGROUND: Human lung cancer is a major cause of death worldwide with few known effective therapeutic modalities. The isoenzyme cyclooxygenase 2 (COX-2) is an inducible inflammatory enzyme with increased activity evidenced in lung carcinoma. The objective was to determine the effect of a selective COX-2 inhibitor on proliferation and apoptosis rates in the Lewis lung (3LL) tumor cell line in vitro. METHODS: First, 1 x 10(4) 3LL cells were plated in a 96-well plate...
