Selenium status in term neonates, according to birth weight and gestational age, in relation to maternal hypertensive pathology.

Background: Pregnancy represents a state of increased oxidative stress and antioxidants, in which selenium (Se) plays a pivotal role, contribute to maintain the oxidative balance. If antioxidant defenses are depleted, placental function is disrupted, resulting in pregnancy complications, including pregnancy-induced hypertension (PIH). Little is known about fetal selenium status in concomitant relation to maternal PIH, gestational age (GA) and birthweight (BW).

Duodenal polyposis, a rare manifestation of gastrointestinal portal hypertension.

Portal hypertension can affect the entire gastrointestinal tract, including the duodenum. Portal hypertensive duodenopathy may occur relatively rare in patients with portal hypertension secondary to cirrhosis or extrahepatic portal venous obstruction. We report the case of a 63-years-old female patient with cirrhosis who underwent an esophagogastroduodenoscopy.

Prognostic Value of Right Ventricular Function Assessed by Echocardiography in Patients Presenting With a First Acute ST Elevation Myocardial Infarction Treated By Primary PCI.

Aims: Informations regarding the prognostic value of right ventricular function changes in the setting of a first acute ST elevation myocardial infarction irrespective of the site of the necrosis and of the left ventricular systolic function are scarce. Purpose of the study was to assess the relation between parameters reflecting global and systolic right ventricular function assessed by conventional, speckle tracking and three-dimensional echocardiography and in hospital major cardiac events (MACE).

Materials And Methods: We have prospectively analyzed a cohort of 44 consecutive patients (mean age 62,71 years, 70.

Mismatch repair gene expression in gastroesophageal cancers.

Background/aims: Mismatch repair (MMR) genes play a critical role in maintaining genomic stability, and the impairment of MMR machinery is associated with different human cancers, mainly colorectal cancer. The purpose of our study was to analyze gene expression patterns of three MMR genes (MSH2, MHS6, and EXO1) in gastroesophageal cancers, a pathology in which the contribution of DNA repair genes remains essentially unclear.

Materials And Methods: A total of 45 Romanian patients diagnosed with sporadic gastroesophageal cancers were included in this study.

Hysterectomy for benign uterine pathology: comparison between robotic assisted laparoscopy, classic laparoscopy and laparotomy.

The aim of our study was to compare several parameters related to robotic surgical procedures in uterine pathology, and to analyse clinico-biological parameters that may influence the post-operative evolution of the patients.

Study Design: Retrospective analysis of 100 patients with uterine pathology who had undergone robotic-assisted laparoscopic surgery at the Santa Chiara Hospital, Pisa, Italy, between 2008 and 2010.

Expression of vascular endothelial growth factor and epidermal growth factor receptor in pancreatic ductal adenocarcinomas, neuroendocrine tumours and chronic pancreatitis.

Objective: Angiogenesis is a crucial event for pancreatic carcinogenesis, and it also plays an important role in chronic pancreatitis. The aim of our study was to evaluate the mRNA expression of vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) in chronic inflammatory or malignant pancreatic pathology in order to elucidate the differences in expression patterns and potential clinical implications.

Methods: Thirty-five patients who had undergone endoscopic ultrasonography followed by endoscipic ultrasound-guided fine needle aspiration (EUS-FNA) of focal pancreatic masses were included in the study.

IL-1RN +2018T>C polymorphism is correlated with colorectal cancer.

Epidemiological and experimental evidence indicates chronic inflammation as a risk factor for colorectal cancer. We investigated whether IL-1B -511C>T (rs16944), IL-1B +3954C>T (rs1143634) and IL1-RN +2018T>C (rs419598) cytokine polymorphisms are correlated with colorectal cancer. Blood samples were obtained from 377 Romanian subjects: 144 patients with sporadic colorectal cancer and 233 healthy controls.

Interleukin-4 receptor -3223T→C polymorphism is associated with increased gastric adenocarcinoma risk.

Background: Gastric cancer remains one of the most common types of cancer worldwide, with a large geographical variation in incidence and mortality rates. Cytokine polymorphisms are the most studied host polymorphisms and are associated with an increased risk of stomach cancer in many regions, but have not been studied extensively in Eastern European populations.

Objective: To investigate the potential association between five cytokine promoter polymorphisms (interleukin [IL] 1b -511C→T [rs16944], IL-4 receptor [IL-4R] -3223C→T [rs2057768], IL-8 -251T→A [rs4073], IL-10 -1082A→G [rs1800896] and tumour necrosis factor-alpha -308G→A [rs1800629]) and susceptibility to gastric adenocarcinoma in a Romanian population.

VEGF-A and VEGF-B mRNA expression in gastro-oesophageal cancers.

Introduction: Angiogenesis is essential for the local growth, invasion and metastasis of the tumours. Vascular endothelial growth factors (VEGFs) play a crucial role in tumour angiogenesis. The aim of our study was to quantify the expression of several VEGF family molecules in human gastro-oesophageal cancers and to analyse possible correlations between genes expression and clinico-pathological features.

IRGM gene polymorphisms and risk of gastric cancer.

Objective: The study aimed to assess the possible association of polymorphisms in the autophagy gene IRGM (rs13361189 and rs4958847) with the risk of gastric cancer.

Methods: A total of 102 patients with gastric adenocarcinoma, 52 with chronic gastritis and 351 healthy controls were included in this study. IRGM allelic variants were genotyped by quantitative real-time polymerase chain reaction.

Contrast-enhanced power Doppler endosonography and pathological assessment of vascularization in advanced gastric carcinomas--a feasibility study.

Aim: Besides representing angiogenesis markers, microvascular density (MVD) and vascular endothelial growth factor (VEGF) are two important tools for the assessment of prognosis in patients with gastric cancer. The aim of our study was to assess the Doppler parameters (resistivity and pulsatility indexes) and vascularity index (VI) calculated by contrast-enhanced power Doppler endoscopic ultrasound (CEPD-EUS) in correlation with the expression of intra-tumoral MVD and VEGF in patients with gastric cancer.

Material And Methods: The study included 20 consecutive patients with advanced gastric carcinoma, but without distant metastasis at initial assessment.

MMR gene expression pattern in sporadic colorectal cancer.

Background And Aims: Colorectal carcinoma is the second leading cause of death by cancer in Europe as its incidence increases with life span. Continuing research to detect new highly sensitive and specific noninvasive biomarkers is essential. The aim of this study was to compare 9 mismatching repair (MMR) genes activation levels in normal, polyp and malignant tissues in order to detect a MMR gene expression pattern in sporadic colorectal malignant pathology.

Wilson's Disease: a challenge of diagnosis. The 5-year experience of a tertiary centre.

Background: Because molecular diagnosis is considered impractical and no patognomonic features have been described, diagnosis of Wilson's disease (WD) using clinical and biochemical findings is still challenging.

Patients And Method: We analysed predictive factors for the diagnosis in 55 patients with WD diagnosed in our centre between 1st January 1999 and 1st April 2004. All patients presented predominant liver disease classified as: 1) asymptomatic, found incidentally, 2) chronic hepatitis or cirrhosis, or 3) fulminant hepatic failure.

Possibilities of perfecting antimicrobial therapy. Dynamics of penicillin G concentrations in the cerebro-spinal fluid in purulent meningitis.

In 43 adult patients with purulent meningitis receiving daily doses of 1-4,000,000 IU penicillin G i.v. in bolus, determinations were made, 1-6 hrs after administration, in 153 samples of cerebrospinal fluid (CSF), to ascertain the concentrations of penicillin that have reached the CSF.

Value of serological tests in the diagnosis of viral acute respiratory infections in adults.

The dynamics of the antibody response to influenza viruses A (H1N1), A (H3N2) and B, to parainfluenza viruses 1, 2, 3, to adenoviruses and respiratory syncytial virus was studied in paired serum samples collected from 110 patients hospitalized with acute respiratory infections (ARI) and in 40 patients suffering from other diseases. Rises in serum antibody titers to 1--5 of the above mentioned antigens were detected in many of the patients of both groups. The fact is most likely due to the presence of some epidemiologically and clinically uncharacteristic viral ARI (influenza included); simultaneous or successive infections with influenza virus and different other viruses were very frequent.
