Videocapsule endoscopy (VCE) can identify lesions in the small bowel which would otherwise be hard to detect. We have selected 53 patients with digestive symptoms in which upper and lower endoscopy had provided no findings. Patients were classified into three groups, based on their main indication for VCE exploration: group one--obscure gastrointestinal bleeding (OGIB); group two--unspecific abdominal symptoms; group 3--monitoring of a prior known pathology. We found that VCE has high predictive values, sensibility and specificity in the diagnosis of OGIB. VCE was also useful in the detection and extent evaluation of lesions in Crohn's and celiac disease. VCE is also able to detect tumors of the small bowel with sufficient accuracy, and can be used to monitor patients with hereditary pre-malignant diseases such as FAP. There were few light adverse effects and no major complications. We conclude that VCE is a safe and effective procedure for the detection of small bowel lesions.

Hepatitis C virus represents one of the major health problems of actual world, as almost 170 million of world population and 1 million persons in Romania are infected with HCV. Considering the increasing importance of HCV, it is imposed that we elucidate the molecular mechanisms, which are the base of hepatic fibrogenesis and potential targets for therapy, for diminishing progression to cirrhosis and avoid the appearance of complications. Activation of stellate cells is the main event in hepatic fibrosis. They also express almost all key components needed for the pathological degradation of matrix and that is why they play an important role not only in the production, but also in the degradation of the matrix. Recently, the worldwide research has also been oriented towards another type of cells with possible function in fibrogenesis and response to antiviral therapy: hepatic progenitor cells. The presence of hepatic progenitor cells in chronic C viral hepatitis is associated with severity of the disease, grade of fibrosis and the risk of hepatocarcinoma. Traditionally perceived as irreversible, reversibility of advanced fibrosis has been described recently in antiviral therapy trials for chronic C viral hepatitis. The favorable effect of interferon therapy on hepatic histology, including fibrosis, has been shown even in patients without sustained virusological response. During the last years, the advantages of the so-called support therapy using interferon have been demonstrated in patients with an increased rate in progression of fibrosis. Further research of the factors associated with progression of fibrosis will allow optimization of criteria for patient's antiviral therapy.

Polycystic kidney disease represented by autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD) have a major impact of mortality in children. We conducted a study of a premature infant with an estimated gestation date of 32 weeks with a presumptive prenatal diagnosis of right polycystic kidney. A 28-year-old primigravida with pre-eclampsia was admitted at the gynecology unit of Clinical Emergency County Hospital of Craiova. The clinical examination revealed a large abdominal distention due probably to the right polycystic kidney, suspected on prenatal ultrasound and radiography. The preterm neonate undergone right nephrectomy 5 days after birth. Histopathology of the kidney was performed in the Pathology Department of the Emergency County Hospital of Craiova and in the Center for Microscopic Morphology and Immunology of U.M.F. of Craiova. Microscopy revealed dilated cysts lined by simple cuboidal or flattened epithelium, and islets of remnant kidney parenchyma separated by edematous stroma. Immunohistochemistry for CD34 revealed incomplete blood arcades which did not seem to be in contact with all the tubular elements of the parenchyma, when compared to a control age-matched kidney. The patient had a favorable postoperative evolution, she was clinically stable on discharge from the hospital with a follow-up strategy including genetic testing.
RESUMO
Wireless capsule endoscopy represents a color imaging technology in the field of medical endoscopy that is extensively used to detect lesions of the human digestive tract. It is the golden standard in evaluating small bowel lesions, offering a set of digital snapshots difficult to get using other investigation methods. Its major drawbacks are the time consumed for image analysis and the burden for the physicians that must spot and classify lesions within more than 55000 images. This paper carries out a study on the detection of telangiectasia in the small bowel, based on an adapted color slicing technique applied not only on unique frames, but on series of successive frames, performing a global analysis suitable on partial sequences or entire wireless capsule endoscopy movies. We have quantified the extracted features and determined a weighting algorithm to find telangiectasia lesions. For frames containing potential lesions, we have determined features not only for the global image, but also for the normal mucosa surrounding the lesion extracted from the image. This approach allows the physician to see variations of parameters within a frame or a sequence that contains lesions. Experimental results prove that the algorithm is effective in detecting telangiectasia patterns of different images, with an accuracy of 93.88%, reducing thus the time spent for the analysis of the images acquired by wireless capsule endoscopy.
RESUMO
The hepatorenal cystic (HRC) syndrome is a heterogeneous group of severe monogenic conditions that may be detected before birth. Effective programme evaluation of children with HRC syndrome is a systematic way to identify the renal and urinary tract malformations which represent the most common cause of end-stage renal disease (ESRD). We conducted a study involving 50 patients, who were between 3 months and 16 years of age, with multiple admissions in the Nephrology Department of "Maria Sklodowska Curie" Children Emergency Hospital from Bucharest, during 6 years (April 14th 2010-October 24th 2016), to evaluate the HRC syndrome. The admission symptomatology was mainly represented by the nephrology evaluation which was essential in the management of children's polycystic kidney disease. For example, a premature infant (gestational age=32 weeks) with positive heredo-collateral history (mother and grandmother were diagnosed with polycystic kidney disease), was tested positive for cystic renal disease after the fetal morphology was performed. It was also done a genetic determination for the presence of PKD1 and PKD2 mutations which are specific to autosomal dominant polycystic kidney disease-ADPKD. However, the genetic test was negative and a postnatal nephrological evaluation was performed using renal ultrasound. The image revealed autosomal recessive polycystic kidney disease-ARPKD. This study emphasizes the importance of an early diagnosis (prenatal, neontal, postnatal) correlated with the admission symptoms and also with the genetic diagnosis (mutations of PKD1 and PKD2).
RESUMO
The early diagnosis of esophageal cancer is necessary for improving the surviving of patients with this disease. To ensure an accurate staging, there are necessary imaging tests to establish the local and regional extension, as well as excluding the metastases. Computed tomography (CT), endoscopic ultrasonography (EUS), and positron emission computed tomography (PET-CT) constitute standard methods for esophageal cancer staging. These techniques are complementary; using only one of these tests is not suitable for correct staging. The role of EUS has improved the doctors' ability to evaluate and select the patients to undergo surgery, radiotherapy, or chemotherapy.
RESUMO
INTRODUCTION: Hepatocellular carcinoma (HCC) represents a major health concern worldwide; identifying risk factors and associated conditions that may lead to its development are therefore of utmost importance to the medical community. An association between diabetes mellitus (DM) and development of HCC on underlying liver conditions has been previously suggested. The aim of our study is to reveal possible significant statistical correlations between the two entities, which might warrant further study of the pathophysiological mechanisms behind this association. PATIENTS AND METHODS: We have prospectively included consecutive cirrhotic patients admitted to our medical clinic over a period of four years, between 2010 and 2014. Diagnostic was established using the EASL criteria. We have documented history of hyperglycemia and any changes of serum values in these patients, evaluating DM patients within the LC lot. From these patients we have selected all patients with imaging suggestive for HCC and established positive diagnosis on the criteria established in the latest EASL guidelines. We have used statistical tests to identify possible correlations between these pathologies. RESULTS: We have identified 2718 consecutive patients with LC and successfully included 2556. Of these, 164 also had HCC. A total of 371 patients had DM - 54 also had HCC while 317 remained cancer-free through our study period. We found positive correlations between the presence of DM and HCC. Subgroup analysis of the HCC cohort revealed a positive association between DM and liver cirrhosis and chronic hepatitis. We did not find positive relationships between DM and overall liver conditions, splenomegaly, hepatomegaly, other significant symptoms, substance abuse and main serum values. CONCLUSIONS: We have found several significant correlations between DM and underlying liver conditions in a HCC cohort. Our study, however, did not reveal other significant associations regarding these diseases. Further studies are required to determine the precise role this disease plays in the development and severity of liver diseases.
RESUMO
INTRODUCTION: The aim of this study is to evaluate the expression of beta-2 adrenergic receptors in the normal peritumoral tissue at the colorectal level, just after the front tumor invasion, in patients with colorectal cancer. METHODS: In this study we analyzed normal peritumoral tissues belonging to 56 patients, who were diagnosed with colorectal adenocarcinoma. These tissues were fixed in paraformaldehyde and paraffinembedded. The immunohistochemical study was done on seriate slides following the hematoxylin and eosin staining, after diagnostic and grading. Correlations were made between beta-2-adrenoreceptors' expression in the normal peritumoral tissue and the clinical and histopathological parameters of the patients with colorectal cancer. RESULTS: There are positive correlations between the expression of beta-2-adrenoreceptors and feminine gender, age group under 50 years, tumor size under 5cm, tumor invasion T3-4 and tumor metastasis in regional lymph nodes N≥2. By analyzing the expression of beta-2-adrenoreceptors in peritumoral tissue depending on tumor grading one can notice that there are positive correlations between beta-2-adrenoreceptors' expression and poorly differentiated colorectal adenocarcinoma. CONCLUSIONS: Positive correlation between this type of receptors in normal glandular epithelium, in the vicinity of tumor invasion front of colorectal neoplasm, and certain clinicopathological features suggests the involvement of tumor microenvironment, which expresses them, in the pathogenesis of this neoplasm.
RESUMO
Bile reflux gastritis is due to an excessive reflux of duodenal contents into the stomach. The increased enterogastric reflux may provide the basis for increased mucosal injury. Bile reflux gastritis can appear in two circumstances: gastric resection with ablation of pylorus and primary biliary reflux due to the failure of pylorus. The aim of the study was to evaluate the endoscopical and histological changes caused by duodenal reflux on the gastric mucosa. The mucosal features were correlated with the risk factors involved in the development of bile reflux gastritis. Our study included 230 patients with alkaline reflux gastritis admitted in Medical Clinic no. 1, Emergency County Hospital Craiova. In all cases we performed an upper gastrointestinal endoscopy. Multiple biopsies were taken from gastric mucosa in 89 patients and the histological features were scored in accordance with the Sydney system. The average age of the patients with bile reflux gastritis was 58.387 years and the incidence of alkaline reflux gastritis was higher between 51 and 80 years. Reflux gastritis was noted to 138 males lpar;60%rpar; and 92 females (40%), ratio males/females was 1.5/1. The most frequent risk factors for bile reflux gastritis were gastric and biliary surgery. Alkaline reflux gastritis was observed in 167 cases (72.6%) after gastric surgery, consisting in gastric resection, pyloroplasty and gastroenteric-anastomosis. Gastroduodenal reflux after biliary surgery was noted in 17 cases (7.39%), 13 cases (5.69%) with cholecystectomy and four cases (1.73%) with biliary anastomosis. The average time interval from original operation to the discovery of the alkaline reflux gastritis was 14.91 years after gastric surgery and 15.29 years after biliary surgery. The commonest endoscopic alterations were: erythema of the gastric mucosa in 139 cases (64.43%), the presence of bile into the stomach in 133 cases (57.83%), the thicken of gastric folds in 22 cases (9.55%), erosions in 12 cases (5.22%), gastric atrophy in 12 cases (5.22%), petechiaes in five cases (2.17%), intestinal metaplasia one case (0.43%) and gastric polyp one case (0.43%). The histologic alterations observed from tissues collected during endoscopic examination were: chronic inflammation in 75 cases (84.06%), foveolar hyperplasia in 36 cases (40.44%), intestinal metaplasia in 31 cases (34.83%), acute inflammation in 16 cases (16.08%), Helicobacter pylori infection in 16 cases (16.08%), chronic atrophic gastritis in 12 cases (13.46%), gastric polyps in 12 cases (13.46%), dysplasia in 10 cases (11.23%), benign ulcerations in seven cases (3.04%), edema in six cases (6.74%) and neoplasia two cases (2.24%). Conclusions. Bile reflux gastritis was more frequent to male gender. The most frequent risk factors for alkaline reflux gastritis were gastric and biliary surgery. Reflux gastritis after gastric resection, pyloroplasty and gastroenteric-anastomosis were more frequent to male gender, while cholecystectomy and biliary anastomosis were predominantly to female gender. The average time interval from original operation to the discovery of the bile reflux gastritis was similar after gastric and biliary surgery. The commonest endoscopic alterations were: erythema of the gastric mucosa, the presence of bile into the stomach, thickens of gastric folds, erosions, gastric atrophy, petechiaes, intestinal metaplasia and gastric polyp. Acute inflammation, Helicobacter pylori infection, gastric polyps and benign ulcerations were more frequent in patients with bile reflux gastritis after gastric surgery, while edema and dysplasia were increased after biliary surgery.

The diagnosis of primitive hepatocellular carcinoma, infiltrative form, arose on liver cirrhosis is often difficult because the imagistic investigations could not relevate the tumoral formation. We are presenting the case of a 56 years patient, diagnosed with viral B liver cirrhosis, in which the clinical symptomatology and laboratory investigations were leading to hepatocellular carcinoma, but the ultrasonography and CT scan could not confirm the malignant transformation. In these conditions we performed ultrasonographically guided biopsy from the liver parenchyma and visualized thrombus in portal vein lumen. Histopathological exam from the thrombus tissue samples confirmed hepatocellular carcinoma diagnosis.

Hepatitis C virus infection can cause progressive liver injury and lead to fibrosis and eventually cirrhosis. Peginterferon alfa-2a represents a significant advance in the treatment of patients with chronic hepatitis C. The aim of the study was to investigate the efficacy, safety and tolerability of the therapy with Peginterferon alfa-2a plus Ribavirin in patients with chronic hepatitis C. The study was made on a number of 37 patients with chronic hepatitis C, admitted in Medical Clinic no. 1, Emergency County Hospital Craiova. The diagnosis of chronic hepatitis was established by means of clinical, biological and morphological investigations. Patients received 180 mug subcutaneously of Pegasys, once weekly, along with either 1000 or 1200 mg/day of Copegus, depending on their weight, for 48 weeks, with 24 weeks of treatment -- free follow-up. We evaluated: sustained virological response, histological response and adverse events. All patients were monitored using blood tests, control of viremia and liver functional tests. Analysis viral response revealed that 11 patients (29.72%) achieved sustained virological response. Histological response was obtained in 20 cases (54.05%) with chronic hepatitis C. The adverse events for Pegasys and Copegus combination therapy were reported in 21 cases (56.72%). Antiviral therapy had positive effect on subjective symptoms in almost half of patients included in our study. An improvement of liver functional tests was noted in the most cases. A third of patients who received Peginterferon alfa-2a plus Ribavirin had sustained virological response. Histological response was noted both at patients with sustained virological response and with unsustained virological response. The side effects of the antiviral treatment are frequent and the severe ones, which require dose reduction, are present at a low number of patients.

The study of chronic viral hepatitis represents a real challenge for modern medicine. If we also analyze this illness from the point of the mental changes involved, the complexity of the study increases. To the etiological, symptomatological polymorphism, alongside the paraclinical and conduct diagnosis, there may be easily added the multitude of mental disorders. The authors have tried, through this paper, to draw the attention upon the importance of studying certain mental disorders connected to a somatic disease, each and every representing a distinct entity, but which together may reach a remarkable complexity.
RESUMO
RATIONALE: Renal dysfunction has a serious impact on the natural evolution of liver cirrhosis. Treatment and prognosis may be improved if an early diagnosis could be established, and specific therapeutic interventions would be applied. Although RIFLE and AKIN classifications have been successfully implemented in the clinical practice of Nephrology and Intensive Care Units, these did not provide major improvements in patients with liver cirrhosis. In the last decade, various biomarkers of kidney injury have been assessed, and Neutrophil Gelatinase-Associated Lipocalin (NGAL) is one of the most promising and most studied novel biomarker. OBJECTIVE: To offer a brief evaluation on current data on the utility of this biomarker in patients with liver cirrhosis. METHODS AND RESULTS: We have searched through current literature and analyzed all significant full text articles on this topic. DISCUSSIONS: NGAL and other new kidney injury molecules may be useful in patients with liver cirrhosis, particularly in identifying structural kidney dysfunction, but larger validation studies to confirm this observation are needed.

Wireless capsule endoscopy is one of the most recent investigation techniques of gastrointestinal pathology. Unlike conventional upper and lower endoscopy, it has the advantages of being a noninvasive and painless procedure. One of the capsule endoscopy disadvantages is represented by the necessary time to analyze the video frames obtained. Software applications proposed in this purpose could offer support in the images evaluation. Different algorithms have been described in the literature, but further research is needed to establish the practical value of computer vision tools in gastroenterology.
RESUMO
INTRODUCTION: Chronic viral hepatitis represent major health problems worldwide, with an evolution that is sometimes marked by a series of extrahepatic manifestations. Among these, kidney disease may occur, either as glomerulonephritis, and/or renal dysfunction. MATERIAL AND METHODS: The purpose of this study was to achieve a complete assessment of the liver and kidney function in a series of patients diagnosed with chronic viral hepatitis, in order to identify a possible kidney disease in this context. 104 patients with chronic viral hepatitis B and C, aged between 25 and 80, were included in the study. These patients were assessed by a series of tests that allowed us to perform a complete evaluation of both liver and kidney function: liver cytolysis enzymes, serum bilirubin, markers of cholestasis, markers of viral infection, urinalysis, albuminuria, electrophoresis of urinary proteins, urea, creatinine, and abdominal ultrasound. RESULTS: Glomerular injury was a rare finding in patients with chronic hepatitis. Patients with chronic hepatitis B had glomerular disease in 5,88 % of cases, while 10 % of the patients with hepatitis C presented this type of renal disease. Acute kidney injury was not identified in our patient group. None of the patients in the hepatitis B study group presented chronic kidney disease. CKD was present in two patients with chronic hepatitis C that had no other associated conditions.
RESUMO
Fibrosis assessment is a necessary component of liver disease evaluation not only for prognosis but also for future therapeutic management. Our study objective was to evaluate the accuracy of quantitative assessment of liver fibrosis in patients with chronic viral hepatitis B or C, relying on RTSE results, a method approved and acknowledged in Europe. MATERIAL AND METHODS: Sixty-three consecutive patients diagnosed with chronic viral hepatitis B or C between January 2014 and December 2014 at the Emergency County Hospital of Craiova were enrolled in the study. Patients underwent both TE and RTSE. RESULTS: The reference method used for staging liver fibrosis was TE, based on its recognition and validation by the European guidelines. Fibrosis was classified as follows: 17.47% of patients were staged as F0, 11.11% of patients staged as F1, 14.28% as F2, 17.47% as F3, and 39.68% as F4. Correlation coefficients between measurements for each parameter was done with ANOVA test, in order to identify any differences, according to the fibrosis stage. Valuable information was obtained suggesting that MEAN, SD, %AREA, COMP, Skewness, IDM and Contrast had highly significant differences when related to the Fibrosis Stage (FS) (p<0,001) and ASM had significant differences (p<0,05). As for Kurtosis, ENT and Correlation parameters no significant differences with the FS was found. CONCLUSIONS: Imaging methods of assessing liver fibrosis are of special interest in chronic liver fibrosis assessment. RTSE comes as a potential new technology based on elastogram evaluation which may prove to be more efficient along with larger prospective studies.
RESUMO
HYPOTHESIS: Chronic viral liver disease is often associated with other conditions. Diabetes mellitus (DM) is frequently reported in this context and may play a role in the progression of the liver disease to hepatocellular carcinoma (HCC). Renal disease is also an important extrahepatic manifestation of hepatitis viral infection and its presence is associated with poor prognosis and management issues. OBJECTIVES: Our study had multiple purposes: to determine the frequency of the association between chronic viral liver disease and diabetes mellitus, evaluate the potential of diabetes mellitus as a risk factor for HCC and assess an eventual renal involvement. METHODS AND RESULTS: We included in our study a number of 246 patients with chronic liver disease, from whom 136 were diagnosed with chronic viral hepatitis and 110 with viral liver cirrhosis. These patients were assessed by using a clinical examination and a series of tests, including serum transaminase levels, serum bilirubin, serum albumin, markers of cholestasis, fasting plasma glucose levels, serum creatinine, urea, albuminuria, Addis-Hamburger test, electrophoresis of urinary proteins, abdominal ultrasound and, in some cases, CT examination. We obtained the following results: diabetes mellitus is often associated with chronic liver disease of viral etiology, having been identified in 18.29% of the patients in our study. Age above 60 in patients with chronic hepatitis (p=0.013<0.05) and presence of hepatitis C virus were particularly correlated with the presence of diabetes mellitus. Renal disease was present in 13.4% of the patients with chronic liver disease and it was especially associated with liver cirrhosis and hepatitis C virus. The most common form of renal injury was glomerulonephritis. Acute kidney injury was diagnosed only in cirrhotic patients as hepatorenal syndrome, occurring in 7.27% of the subjects, while chronic kidney disease was identified only in two cases of chronic viral hepatitis. Four patients in our study were diagnosed with HCC and none of them presented diabetes mellitus. DISCUSSION: Our study revealed that there is a significant association between diabetes mellitus and chronic viral liver disease induced by hepatitis C virus. Glomerulonephritis was the most common type of renal disease in both hepatitis patients and in those with cirrhosis. Glomerular injury was strongly correlated with the presence of hepatitis C virus than with hepatitis B virus. A connection between diabetes mellitus and hepatocellular carcinoma could not be established.

Colorectal cancer stands at the top of oncologic pathology in the world, and in the same measure in Romania because is the third most frequent cancer diagnosed in men and women. Colorectal cancer develops as a result of mutations in genes that control proliferation and cell death. It was established that in the development of a tumor there is originally a prevascular phase followed by a phase of tumor angiogenesis. In the future it is necessary to develop new clinical protocols that angiogenesis inhibitors are associated with chemo or radiotherapy, conventional or other methods such as immunotherapy and gene therapy.
RESUMO
OBJECTIVE: This study aims to analyze the stress of the students from the nursing department within the Medical Midwife and Nurse School from our University. SUBJECTS AND METHODS: For this purpose a questionnaire, comprising the factors the students consider important for their academic preparation during the first year, was elaborated and applied to 100 students. RESULTS: The result analysis revealed no significant differences as far as the genders of the subjects were concerned. In the same way, the prior academic background or the student experience did not influence the level of stress. The social and economic factors seem to be involved in choosing a career and thus influence the academic stress. For this purpose, a questionnaire comprising the factors the students consider important for their academic preparation during the first year, was elaborated and applied to 100 students. We used the Students t-test to determine differences between groups and considered p<0.05 as significant. CONCLUSIONS: The stress equally affects the nursing department students, regardless of their gender or prior studies. Social and economic factors play a role in adapting to a new academic environment, having higher expectations and requirements.
