RESUMEN
BACKGROUND: Isolated splenic metastases from endometrial cancer, which is a relatively common malignancy, are extremely rare findings; to date, only 14 cases have been reported in the literature. CASE SUMMARY: We report a patient with isolated splenic metastases of endometrial cancer 3 years after radical surgery of the primary tumor. The patient was successfully treated by splenectomy and six cycles of paclitaxel. Fifty months after splenectomy, she was alive and well, and with no evidence of disease. CONCLUSION: Isolated spleen metastasis of endometrial cancer is very rare. Radical surgery and adjuvant therapy may offer excellent long-term survival.

We aimed to evaluate whether two methionine-related compounds, S-adenosylmethionine (SAM), and selenomethionine (SM), could lessen liver damage induced by regurgitated bile in a model of rat bile duct ligation (BDL). Hepatoprotective potentials of S-adenosylmethionine and selenomethionine were estimated based on the changes of serum liver damage parameters (aminotransferases, alkaline phosphatase, gamma-glutamyltranspeptidase and lactate dehydrogenase activity, and bilirubin concentration), tissue oxidative [xanthine oxidase (XO) and catalase activity, thiobarbituric acid reactive substances (TBARS) levels] and inflammatory [tumor necrosis factor-alfa (TNF-α) concentration] parameters, and morphological liver tissue alterations that follow cholestasis. The treatment regimens proved themselves able to prevent significant liver damage induced by cholestasis. Both SAM and SM decreased XO activity and TBARS levels and increased catalase activity, while only SM significantly reduced TNF-α concentration. Morphological changes related to bile-induced liver damage were also found to be partially diminished by SAM and SM. In view of the mechanisms of action of the two tested methionine-derived compounds, one might say that SM predominantly acted as an antioxidant, while SAM exerted its activity by potentially modulating different gene expression and protein structures. It is also worth mentioning that this is the first study (to the best of our knowledge) that dealt with the effects of SM on BDL-induced liver injury in rats and of the findings that speak favorably of this powerful antioxidant.

Rat bile duct ligation (BDL) represents a useful method that mimics obstructive extrahepatic cholestasis, which is known to be a frequent disorder in humans. Polyamines (putrescine, spermidine, and spermine) are one of the key molecules regulating cell proliferation and differentiation. This work aimed to evaluate the potential beneficial properties of putrescine in rat BDL model by studying several biochemical parameters reflecting liver function and polyamine metabolism. Rats that were subjected to BDL were injected with putrescine (150 mg/kg) for 9 days, while in parallel another group with BDL remained untreated. Two control groups were included as well, sham-opened and putrescine-treated group. The following plasma parameters: ALT, AST, γ-GT, ALP, bilirubin, bile acids, as well as liver malondialdehyde and polyamine concentration and the activity of enzymes involved in polyamine metabolism were studied. After BDL, significant alterations in plasma biochemical parameters occurred, where a 9-day putrescine treatment significantly alleviated liver function deterioration. Putrescine also increased liver polyamines' concentrations and polyamine and diamine oxidase activities in rats submitted to BDL. Our results demonstrated, for the first time, that putrescine plays an important role in preserving liver tissue function in rats with experimentally induced cholestasis.

Stathmin1 is a microtubular regulatory protein. The expression disorders of this protein result in significant changes in cell migration, invasion, adhesion and colony formation in many malignant tumors. The aim of our research was to investigate the effects of Stathmin1 expression on neoangiogenesis in colorectal adenocarcinoma. Biopsy material that was obtained by the resection of colorectal carcinoma was used. The experimental group consisted of operative biopsies of colorectal cancer (n = 72), and the control group (n = 72) consisted of biopsies of adjacent non-tumor colon tissue. The biopsy material was taken from an operative preparation submitted to the Department of Pathology. After histopathological treatment, classical Hematoxylin- Eosin and immunohistochemical ABC methods with anti-Stathmin1, anti-VEGF and anti CD105 antibodies were applied on 4 µm thick sections. High expression of Stathmin1 is associated with severe (91.9%) and moderate (8.1%) expression of VEGF in a significantly high number of cases. This relation is defined by a highly significant correlation coefficient (r = 0.768; p = 0.000). High expression of Stathmin1 is associated with a high microvascular density index (mvdIDX) in a significant number of cases (73.0%) while low expression of Stathmin1 is in relation with low mvdIDX in a significant 73.7% of cases. This relationship is also defined by a highly significant correlation coefficient (r = 0.566; p = 0.000). ROC analysis showed that the sensitivity for Stathmin1 was 97.4% and the specificity was 91.4%. Based on Stathmin1 expression, it is possible to differentiate patients with increased risk for metastatic disease. The highly significant association of Stathmin1 expression with VEGF expression and microvascular density (MVD) suggests that Stathmin1 may be a serious candidate for therapeutic target.
RESUMEN
Congenital esophageal stenosis (CES) is a type of esophageal stenosis, and three histological subtypes (tracheobronchial remnants, fibromuscular thickening or fibromuscular stenosis, and membranous webbing or esophageal membrane) are described. Symptoms of CES usually appears with the introduction of the semisolid alimentation. Dysphagia is the most common symptom, but esophageal food impaction, respiratory distress or failure to thrive can be clinical manifestations of CES. Wide spectrum of differential diagnoses leads to delayed definitive diagnosis and appropriate treatment. Depends on hystological subtype of CES, some treatment procedures (dilation or segmental esophageal resection) are recommended, but individually approach is still important in terms of frequency and type of dilation procedures or type of the surgical treatment. Dysphagia can persist after the treatment and a long follow-up period is recommended. In 33% of patients with CES, a different malformations in the digestive system, but also in the other systems, are described.

Background/Aim: Bleeding from esophageal varices is a significant factor in mortality of patients with terminal liver cirrhosis. This complication is a major health problem for recipients on the list for liver transplant. In that regard, studying predictors of variceal bleeding episode is very important. Also, it is important to find the best survival predictor among prognostic scores. The aim of the study was to compare validity of prognostic scores in assessment of survival in hospital-treated patients after bleeding from esophageal varices, and to compare validity of baseline Child-Turcotte-Pugh (CTP) and Modul for End-stage Liver Disease (MELD) scores with CTP creatinine modified (CTP-crea) I and II scores in assessment of survival in patients within a long-term follow-up period after the episode of bleeding from esophageal varices. Methods: The study included a total of 126 patients suffering from terminal liver cirrhosis submited to testing CTP score score I and II, MELD score, MELD Na score, integrated MELD score, MELD sodium (MESO) index, United Kingdom Model for End-Stage Liver Disease (UKELD) score and updated MELD score. Results: Patients with bleeding from esophageal varices most often had CTP score rank C (46,9%). CTP score rank B had 37.5% patients, while the smallest percentage of patients had CTP rank A, 15.6% of them. Patients who have values of CTP score higher than 10.50 and bleeding from esophagus, have 3.2 times higher chance for death outcome compared to other patients. Patients who have values of CTP-crea I score higher than 10.50 and bleeding from esophagus, have 3.1 times higher chance for death out-come than other patients. Patients who have values of CTP-crea II score higher than 11.50 and bleeding from esophagus, have 3,7 times higher chance for death outcome compared to other patients. Conclusion: Survival of patients with bleeding from esophageal varices in the short-term follow up can be predicted by following CTP score and creatinine modified CTP scores. Patients with bleeding from esophageal varices who have CTP score and CTP-crea I score higher than 10.5 and CTP-crea II score higher than 11.5, have statistically significantly higher risk from mortality within one-month follow-up compared to patients with bleeding from esophageal varices who have lower numerical values of scores of the CTP group.

Introduction/Aim: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease of a broad histological spectrum, characterized by the accumulation of triglycerides in more than 5% of hepatocytes in the absence of consuming alcohol in quantities harmful to the liver. The aim of our study was to determine the importance of anthropometric and laboratory parameters as well as metabolic syndrome (MS) for the diagnosis of NAFLD and to estimate their influence on the degree of liver steatosis as evaluated by ultrasound (US). Methods: The study included 86 participants, 55 of whom had fatty liver diagnosed by ultrasound and they comprised the study group. The control group consisted of 31 control subjects. During the course of hospitalization at the Clinic of Gastroenterology and Hepatology, Clinical Centre Nis, the patients had their anamnesis taken, and anthropometric measurements as well as biochemical blood analyses and abdominal ultrasound were performed. Results: The patients with NAFLD had statistically higher values of body mass index (BMI), waist circumference (WC), systolic (SBP) and diastolic blood pressure (DBP), levels of alanin and aspartate aminotransferase (ALT, AST), gamma-glutamyl transpeptidase (GGT) (p<0.001), low-density lipoprotein cholesterole (LDL), total bilirubin (TBIL) (p<0.05), total cholesterol (p<0.01), triglycerides (TGL), urates, C-reactive protein (CRP), ferritin, fibrinogenes, fasting blood glucose (FBG), insulin and Homeostasis Model Assessment (HOMA-IR) (p<0.001), whereas the levels of high-density lipoprotein cholesterol (HDL) were higher in the control group (p<0.05). In the NAFLD group, there were statistically significantly more patients with hypertension (72.73% vs. 12.90%, p<0.001) and type 2 diabetes mellitus (DM) (47.27%). Metabolic syndrome was determined in 48 (87.27%) patients of the study group. An equal number of patients, 16 of them (29.09%), had 3, 4 and 5 components of MS. In the NAFLD group there were 17 overweight (30.91%) (BMI from 25 kg/m2 to 29.9 kg/m2) and 38 (69.09%) obese patients. (BMI ≥ 30.0 kg/m2). The largest number of patients in the obesity group, 22 (40.00%) of them, had the first degree obesity (BMI from 30 kg/m2 to 34.99 kg/m2). The largest number of the NAFLD group patients - 23 (41.82%), had an ultrasound finding of grade 3 fatty liver, 20 patients (36.36%) had grade 2 and 12 (21.82%) grade 1 fatty liver. Kruskal-Wallis test and ANOVA analysis showed statistically significant differences between groups with different US grade for insulin, LDL-cholesterol, WC, BMI (p<0.05), as well as HOMA-IR and body weight (BW) (p<0.01). Metabolic syndrome was statistically more present in patients with US finding grades 2 and 3 (p<0.01) in relation to grade 1 US finding, as well as obesity, hypertension and DM type 2 (p<0.05). Conclusion: The results of our study have confirmed that a high percentage of patients with high risk factors (DM, MS, dyslipidemia, hypertension) have NAFLD.

INTRODUCTION: Certain pro-inflammatory indices serum levels, such as leucocytes count and C-reactive protein appears to be a significant and simple clinical tool in prediction of unfavorable course of liver cirrhosis, its complications due to the bacterial infections, length ofhospitalisation and lethal outcome. Cirrhotic patients often have a complications due to bacterial infection, demanding the unexpected need for hospitalization in 30% to 50% of the cases. THE AIM of this study was to assess the impact of pro-inflammatory indices in patients with liver cirrhosis, in relation to bacterial infection and their evaluation as possible prognostic factors on functional liver deterioration, length of hospitalization and lethal outcome. MATERIAL AND METHODS: The research was conducted as a prospective study, on 120 patients with liver cirrhosis, who were in divided into two groups: I-experimental one of 60 patients with bacterial infection and II-control one of 60 patients, with no infectious complications diagnosed end treated in period 2005.-2010. Year. RESULTS: Most of the patients of experimental group were in C stage of disease, compared to those in the control one (p < 0.001). They had also, initially significantly higher increased values of pro-inflammatory indices, which were significantly reduced during the treatment (p < 0.001), with average longer length of hospitalisation and lethal outcome (p < 0.001; p < 0.01). CRP and the Le count values were most significant predictive factors for length of hospitalisation and lethal outcome. DISCUSSION: Pro-inflammatory indices values may predict an unfavorable course and lethal outcome in cirrhotic patients with bacterial infections. Prevention of bacterial infection in those patients improves their long-term survival, achieving the slower course of the underlying disease.

INTRODUCTION: Trichobezoars are foreign bodies in gastrointestinal tract, composed of hair. They occur mainly in children and adolescents suffering from trichotillophagia. They commonly occur in the stomach, but as they enlarge over time, they can extend through the pylorus into distal parts of the small intestine resembling a tail. This rare form of trichobezoar is named Rapunzel syndrome. CASE REPORT: We presented a 19-year-old female patient, who suffered from trichotillomania and trichotillophagia, which led to trichobezoar formation. Intra-abdominal tumour was suspected after initial clinical examination. Abdominal echosonography, endoscopy and abdominal computed tomography (CT scan) in the pre-operational period revealed trichobezoar formation. The patient was operated on and subjected to further psychiatric treatment. CONCLUSION: Trichobezoar should be differentially diagnostically taken into consideration in younger women with abdominal pain, nausea, vomiting, palpable abdominal mass and psychiatric disorders. Most trichobezoar cases require surgical treatment, whereas the patients need long-term psychiatric treatment and monitoring.

INTRODUCTION: Renal dysfunction is one of complications in patients with obstructive icterus. It is important to recognize it early and take adequate measure to prevent its occurrence. One third of the patients with obstructive icterus have deterioration of renal function before surgical intervention. The aim of the research was to assess the renal dysfunction markers in patients with obstructive icterus. The following factors were examined: diuresis, urinary sodium concentration, sodium excretory fraction, urine osmolality, osmotic concentration index, creatinine concentration index and renal index of lesion. MATERIAL AND METHODS: The study included 85 patients with obstructive icterus (50 patients before surgical intervention and 35 after surgical intervention) and 30 patients without icterus as a control group. The patients with normal renal function before the development of the disease were included. RESULTS: Malignant etiology was present in 39 patients and benign in 46 patients of the examined group. The evaluation parameters (of renal function were examined in all of the patients. Creatinine concentration index led to the greatest change in the coefficient value of an internal consistency, showing that it was the best renal function marker in the examined group of patients with icterus. The next one was the urinary osmolality, since its exclusion would lead to a decrease in the value of Cronbach a coefficient to 0.06. Icterus and surgical intervention show statistically significant effects to change in the value of the markers of laboratory differentiation of renal function, observed as an entire set. DISCUSSION AND CONCLUSION: The examination showed that the concentration clearances of creatinine and urine osmolality are the parameters which point to the probability of renal dysfunction occurrence in obstructive icterus.

INTRODUCTION: Intussusception is a rare phenomenon in adults. It is caused mainly by malignant neoplasm. Primary lymphoma of the colon is a rare malignancy of the large intestine. The association of intussusception in adult and primary colorectal lymphoma is a diagnostic challenge, since they occur with a variety of atypical symptoms. CASE OUTLINE: We report a case of ileocolic intussusception in a 26-year-old man induced by primary lymphoma of the cecum. He was admitted to our hospital for incomplete intestinal obstruction. After thorough diagnostic work-up (plain abdominal radiography, abdominal ultrasonography, multi-slice computerized tomography, colonoscopy with biopsy), the patient underwent surgery. Intraoperative findings confirmed lymphoma as the cause of intussusception. The right hemicolectomy was carried out with end-to-side ileo-transverse anastomosis. CONCLUSION: Primary colorectal lymphomas should be considered in differential diagnosis of intussusceptions in adults. The treatment of choice is a radical resection where all oncological standards must be fulfilled.

BACKGROUND/AIM: The symptoms of gastroesophageal reflux disease (GERD) are among the most common complaints for which patients are indicated for visiting gastroenterologist. It occurs as a result of the effect made by gastric reflux contents that moves into the esophagus. The prevalence of all forms of GERD is 40%. The aim of this study was to analyze the grade of esophagitis, chromendoscopical and histological findings of esophagus in patients with GERD before and after the therapy. METHODS: A prospective study included 90 patients with symptoms of GERD, divided into 2 groups depending on whether they had endoscopic signs of gastroezophageal reflux (group ERD), or not (group NERD). All the patients had esophagogastroduodenoscopy, chromoendoscopy staining, test for Helicobacter pylori and histological findings of the esophagus. In the patients with Helicobacter pylori infection eradication therapy was done. RESULTS: Esophagitis-B level was present in most of the patients. Among the groups, roughly the same number responded to positive findings on chromoendoscopy. After the therapy, chromoendoscopy was significantly negative in both groups of the patients comparing to chromoendoscopy before the therapy (p = 0.00001). Multiplication and elongation of papilla, basal cell hyperplasia, vascular dilatation, increasing of mitotic activity and the presence of polymorphonuclear leukocyte cells were statistically more frequent histological findings in the group ERB compared to the group NERB. After the therapy, the patients in both groups had statistically less histological findings of appropriate esophageal parameters. CONCLUSION: Chromoendoscopy combined with the standard endoscopy increases the sensitivity and specificity for reflux disease. Histology in the reflux disease is associated with endoscopic and clinical findings so that the localization of taking biopsies and histological criteria of pathohistological changes must be clearly defined. Multiplication and elongation of papilla, basal cell hyperplasia and the presence of polymorphonuclear leukocytes are the most relevant criteria in the diagnosis NERD.
