Standards for Quality Improvement Registries on Abdominal Aortic Aneurysm Repair: A Delphi Consensus Report From VASCUNET and International Consortium of Vascular Registries.

Objective: Outcome registries in vascular surgery are increasingly used to drive quality improvement by vascular societies. The VASCUNET collaboration, within the European Society for Vascular Surgery (ESVS), and the International Consortium of Vascular Registries (ICVR) developed a set of variables for quality improvement registries on abdominal aortic aneurysm (AAA) repair as a registry standard.

Methods: Representatives from international vascular registries within VASCUNET, ICVR, and other nations with established registries were invited to provide the variables.

Frailty indices predict mortality, complications and functional improvements in supratentorial meningioma patients over 80 years of age.

Purpose: To assess whether the Modified 5 (mFI-5) and 11 (mFI-11) Factor Frailty Indices associate with postoperative mortality, complications, and functional benefit in supratentorial meningioma patients aged over 80 years.

Methods: Baseline characteristics were collected from eight centers. Based on the patients' preoperative status and comorbidities, frailty was assessed by the mFI-5 and mFI-11.

Epidemiological and Therapeutic Developments in Pelvic Ring Fractures Type C from 2004 to 2014 - a Retrospective Data Analysis of 2,042 Patients in the German Pelvic Register (DGU).

Background: Pelvic ring fractures type C present a special challenge due to their high instability, the possible accompanying injuries and the high mortality rate of up to 18.9%. The aim of this retrospective analysis was to use the data from the DGU pelvic register to identify changes in the epidemiology and therapy for type C pelvic ring fractures between 2004 and 2014.

Genome-wide association study identifies inversion in the locus to modify risk for alcoholic and non-alcoholic chronic pancreatitis.

Objective: Alcohol-related pancreatitis is associated with a disproportionately large number of hospitalisations among GI disorders. Despite its clinical importance, genetic susceptibility to alcoholic chronic pancreatitis (CP) is poorly characterised. To identify risk genes for alcoholic CP and to evaluate their relevance in non-alcoholic CP, we performed a genome-wide association study and functional characterisation of a new pancreatitis locus.

A Novel Grading System Based on Tumor Budding and Cell Nest Size Is a Strong Predictor of Patient Outcome in Esophageal Squamous Cell Carcinoma.

The determination of prognosis in patients with esophageal squamous cell carcinoma (ESCC) is primarily based on staging according to the TNM-classification, whereas conventional grading is of minor clinical importance because of its deficiencies in prognostic patient stratification. Recently, a novel, highly prognostic grading scheme based on budding activity and cell nest size has been proposed for squamous cell carcinoma (SCC) of both pulmonary as well as oral origin. In order to investigate the utility and transferability of this approach to ESCC, we evaluated budding activity and cell nest size, as well as other histomorphologic characteristics, in a cohort of 135 primarily resected tumors and correlated the results with clinicopathologic and outcome parameters.

In vitro evidence for senescent multinucleated melanocytes as a source for tumor-initiating cells.

Oncogenic signaling in melanocytes results in oncogene-induced senescence (OIS), a stable cell-cycle arrest frequently characterized by a bi- or multinuclear phenotype that is considered as a barrier to cancer progression. However, the long-sustained conviction that senescence is a truly irreversible process has recently been challenged. Still, it is not known whether cells driven into OIS can progress to cancer and thereby pose a potential threat.

The influence of pore geometry in cp Ti-implants--a cell culture investigation.

Biocompatibility testing of differently structured titanium implants was performed using an in vitro test system of a newly established human fetal osteoblastic cell line (hFOB 1.19). Cell adhesion of osteoblastic cells on the different porous geometries and the suitability of a copper vapor laser system for surface structuring was tested with the following parameters: cell-number, cell viability, alkaline phosphatase expression.

Multiple endocrine neoplasia 2A syndrome: Surgical management.

Background/purpose: Currently, molecular genetic diagnostics allow familial types of medullary thyroid carcinoma to be detected at an asymptomatic stage and surgery thus to be performed at a time when prognosis is good. The current report aims to determine the appropriate age for safe prophylactic thyroidectomy in children with multiple endocrine neoplasia (MEN) 2A and mutations at codon 609 according to genotype-phenotype correlations and will discuss surgical procedures.

Methods: The authors describe the case of a family with hereditary MEN 2A syndrome.

A fixed-dose combination of low molecular weight heparin with dihydroergotamine versus adjusted-dose unfractionated heparin in the prevention of deep-vein thrombosis after total hip replacement.

The low dose heparin regimen (LDH) is not appropriate for prevention of intra- and postoperative thromboembolic complications in high risk patients, especially those undergoing elective hip replacement. Despite LDH prophylaxis, the incidence of deep-vein thrombosis (DVT) remains in a range of 20 to 35%. Adjusted-dose unfractionated heparin prophylaxis is thought to be one of the most effective regimens for thrombosis prophylaxis in this indication, but it requires two or three daily injections as well as precise monitoring of the activated partial thromboplastin time (aPTT).

Effect of hepatocyte growth factor on the expression of E- and P-cadherin in gastric carcinoma cell lines.

Hepatocyte growth factor (HGF), identical to scatter factor, (SF) is a secretory glycoprotein from fibroblasts which dissociates and increases the motility of various types of epithelial cells. After treatment of three gastric carcinoma cell lines (MKN-28, MKN-45 and TMK-1) with HGF (10 ng/ml), TMK-1 cells lost their tight cell to cell contact and showed marked scattering, while the two other cell lines remained unaffected. To learn about the underlying mechanism of the HGF induced scattering, we examined the expression of adhesion molecules and growth factor/receptor systems at the mRNA and protein level.

Treatment of pilonidal sinuses by phenol injections.

Six female and 39 male outpatients, who suffered from acutely inflamed pilonidal sinus were treated by sclerotherapy between January 1985 and December 1988. Under local anaesthesia, 1-2 ml 80% phenol was injected into the sinus. The phenol, which was allowed to act for a minute, was washed out by irrigating the sinus with physiological common-salt solution.

Osteoclastic giant cell tumor of the pancreas. An immunohistological study and review of the literature.

A case of an osteoclastic giant cell tumor of the pancreas is presented. The different surgical specimens during the forty months of observation suggest that the histological feature of the tumor has changed. Although immunohistological studies were performed, the histogenesis remains obscure.

Carcinosarcoma in Barrett's oesophagus: a case report with immunohistological examination.

A case of a carcinosarcoma which developed in a Barrett's oesophagus is presented. The tumour consisted of an adenocarcinoma and a spindle cell sarcoma. Immunohistological examinations demonstrated vimentin positivity in the sarcomatous portion with a negative reaction for keratin.

Mamma-augmentation-plasty after operation for funnel-chest deformity.

A technique for correction of funnel chest, a condition found in 91% of chest deformities, has been successfully used in 1141 patients. Among these were 38 females, 4 of whom had mamma-augmentation-plasty performed at the time of removal of the metal strut used in repair of the funnel chest. Great care is needed in selecting patients for the repair of funnel chest and in avoiding postoperative complications.
