Institutional review of patients presenting with suspected appendicitis.

Background: Appendicitis is a common gastrointestinal surgical emergency. Treatment balances the risks of negative appendicectomy (NA) against potential complicated appendicitis in determining clinical priority. This study reviewed the population characteristics, results of the diagnostic modalities and Alvarado score (AlvS) of patients with suspected appendicitis.

An audit of operative notes: facts and ways to improve.

Background: Accurate operation record keeping is an important element of risk management. Handwritten surgical notes are often produced as evidence in medico-legal malpractice cases and incomplete and illegible notes may be a source of weakness in a surgeon's defence. Therefore, we audited the surgical notes in a teaching hospital surgical department.

Transcriptional silencing of ETS-1 efficiently suppresses angiogenesis of pancreatic cancer.

In this study, we addressed the hypothesis that transcriptional suppression of erythroblastosis virus E26 oncogene homolog 1 (ETS-1) is an efficient therapeutic approach to pancreatic adenocarcinoma by investigating the effect of ETS-1 suppression in human pancreatic cancer cells. We accomplished this by using an adenoviral vector encoding only the DNA-binding domain of wild-type ETS-1 (ETS-1 dominant negative, ETS-1-DN). ETS-1-DN decreases ETS-1-binding by competing for its binding to DNA.

[The impact of patient and tumor related prognostic factors on survival in non-medullary differentiated thyroid cancer. A study of 125 cases].

Unlabelled: The aim of the study was to assess the impact of patient--(age) and tumor--related factors (size, extrathyroidal invasion, distant metastasis, multicentricity and lymphatic metastasis) on survival of patients with differentiated thyroid cancer (DTC).

Material And Method: A clinical retrospective study was carried out on a series of 125 patients operated for non medullary DTC in the IIIrd Surgical Unit, in the period 1990-2005. The disease specific survival (DS) was calculated using the Kaplan Meyer method and Cox regression univariate and multivariate analysis was used to assess the impact of prognostic factors on DS.

The PMAIP1 gene on chromosome 18 is a candidate tumor suppressor gene in human pancreatic cancer.

Frequent loss of heterozygosity on the long arm of chromosome 18 is observed in pancreatic cancer. Previous studies suggested the existence of one or more tumor-suppressor genes other than SMAD4 on chromosome 18. To identify the candidate tumor-suppressor gene(s), we compared gene expression by cDNA microarray analyses using a pancreatic cancer cell line Panc-1 and its hybrid cell lines showing suppressed cell growth after introduction of one normal copy of chromosome 18.
