Specific codon 13 K-ras mutations are predictive of clinical outcome in colorectal cancer patients, whereas codon 12 K-ras mutations are associated w…

2002

Background: K-ras mutations, one of the earliest events observed in colorectal carcinogenesis, are mostly found in codons 12 and 13, and less frequently in codon 61, all three of which are estimated to be critical for the biological activity of the protein. Nevertheless the prognostic significance of such mutations remains controversial. Our purpose was to assess whether any or specific K-ras mutations in primary colorectal cancer had prognostic significance and were linked to clinico-pathological parameters. Patients and methods: Paired tumor and normal tissue samples from a consecutive series of 160 untreated patients (median of follow up 71 months), undergoing resective surgery for prima…

Treatment of stages IIIIV of the Dupuytrens Disease using a personal approach: percutaneous needle fasciotomy (PNF) and minimal invasive selective ap…

2013

Abstract The authors present their experience in treating 23 fingers on 20 patients affected by Dupuytrens Disease in stages III and IV of the Tubiana classification with their personal technique that involves the percutaneous needle fasciotomy followed 40 days after by a selective open aponeurectomy on the previously treated cord, by making a small cutaneous incision. The treatment requires careful selection of the patients. In fact, patients suffering from the disease for more than 5 years and all the cases with a suspicion of joint rigidity are excluded from the study. The average follow up period was approximately 48 months. 18 out of the 20 patients had excellent functional recovery. S…

Orthokeratinized odontogenic cysts: a Spanish tertiary care centre study based on HPV DNA detection

2018

Abstract Background The role of human papillomavirus (HPV) in orthokeratinized odontogenic cysts (OOCs) has rarely been studied. The objective is to describe the clinicopathological findings in a series of OOCs from a Spanish population that were investigated in relation to the possible presence of HPV. Methods A clinicopathological retrospective analysis followed by a molecular analysis of 28 high- and low-risk HPV genotypes was performed in OOC samples of patients seen during the last 15-years in a Spanish tertiary care center. Results Of 115 odontogenic cysts with keratinization, 16 cases of OOCs were confirmed and evaluated. OOCs occurred predominantly in the mandible of males (mean age…

Effect of mesalazine on epithelial cell proliferation in colonic diverticular disease

2007

Background and aims: increased epithelial cell proliferation may be detected in diverticular disease, but antibiotics have failed in reducing it. We assess therefore the effect of mesalazine on epithelial cell proliferation in diverticular disease. Methods: a prospective study was conducted on 20 consecutive patients with a new endoscopic diagnosis of symptomatic uncomplicated diverticular disease. The patients were treated with mesalazine 1.6 mg/day for 1 year. The Ki-67 antigen index of the whole crypt and in the upper third was separately evaluated before and after starting the treatment. Results: cell proliferation index was higher in diverticular disease patients than healthy controls …

Muscle fiber-type distribution predicts weight gain and unfavorable left ventricular geometry: a 19 year follow-up study

2006

Abstract Background Skeletal muscle consists of type-I (slow-twitch) and type-II (fast-twitch) fibers, with proportions highly variable between individuals and mostly determined by genetic factors. Cross-sectional studies have associated low percentage of type-I fibers (type-I%) with many cardiovascular risk factors. Methods We investigated whether baseline type-I% predicts left ventricular (LV) structure and function at 19-year follow-up, and if so, which are the strongest mediating factors. At baseline in 1984 muscle fiber-type distribution (by actomyosin ATPase staining) was studied in 63 healthy men (aged 32–58 years). The follow-up in 2003 included echocardiography, measurement of obes…

Accuracy, sensitivity and specificity of fine needle aspiration biopsy in salivary gland tumours: A retrospective study

2010

Objective: the aim of this study was to evaluate the diagnostic accuracy, sensitivity and specificity of fine needle aspiration biopsies (FNAB) of salivary gland tumours performed at the Erasto Gaertner Hospital over the course of a four year period. Study design: A retrospective study was carried out between 2001-2005 to review the cases of patients with salivary gland tumours who had undergone pre-operative FNAB and had been diagnosed during post-operative histopathology examination. Results: A total of 106 cases of salivary gland tumours were considered for this study, but 27 cases (25.5%) of the samples were considered unsatisfactory for analysis. the sensitivity, specificity and accura…

Management of pre-malignant and malignant lesions by endoscopic resection

2003

Endoscopic resection (ER) has gained more and more importance in the treatment of early gastrointestinal neoplasia over the last few years. The choice of the different available techniques depends on the site, the macroscopic type of the tumour and the personal experience of the endoscopist. The 'suck-and-cut' technique with ligation device or cap should be favoured to normal strip biopsy in the oesophagus because of the size of the resected specimen and its technical feasibility. A recently described method of ER in the stomach is the circumferential mucosal incision with a type of needle-knife and subsequent en-bloc resection following prior injection under the lesions. ER of high-grade i…

Fabry disease: enzyme replacement therapy

2003

Fabry disease is a multisystem disorder associated with wide variability in clinical expression. Fabry disease is an X-linked lysosomal storage disorder caused by a deficiency of alpha-galactosidase A. The enzyme defect leads to the systemic accumulation of glycosphingolipids with alpha-galactosyl moieties consisting predominantly of globotriaosylceramide, galabiosylceramide and two additional glycosphingolipids. Four hemizygotes patients with a family history of Fabry disease and deficiency of the enzyme alpha-galactosidase A were selected. Each patient received purified alpha-galactosidase by intravenous infusion (0.2 mg/kg). The infusion was administered every 2 weeks, for 40 min, for a …

Effects of 8 weeks' endurance training on skeletal muscle metabolism in 56?70-year-old sedentary men

1977

The effects of 8 weeks' endurance training on muscle metabolism at rest and after a submaximal bicycle ergometer exercise were studied in 31 previously sedentary men, aged 56-70. Training consisted of 3-5 one hour exercise bouts per week including walking-jogging, swimming, gymnastics and ball games. The effects of training were similar to those previously reported for younger men. Mean maximal oxygen uptake increased (11%), as did the resting values for muscle glycogen concentration, the enzymes representing aerobic energy metabolism (malate dehydrogenase, succinate dehydrogenase), and also some of the anaerobic enzymes (creatine phosphokinase, lactate dehydrogenase). Lactate production du…
