RESUMEN
Aim: The aim of this retrospective study was to identify the clinical, radiological, and histological characteristics of patients diagnosed with osteonecrosis of the jaw (ONJ) and treated at the Oral and Maxillo-Facial Surgery Clinic of the Emergency Clinical County Hospital of Targu Mures between 2017 and 2022. The study aimed to analyze correlations between patient characteristics, particularly their history of bone modifying agent use or local radiotherapy during cancer treatment, in order to identify specific patient profiles that could aid in evaluating treatment response and guide individualized treatment strategies. Methods: Fifty-two patients diagnosed with ONJ were included in the study. The patients were divided into two groups based on their medical history: the bone modifying agent use group and the radiotherapy group. Clinical, radiological, and histological data were collected and analyzed. Statistical analysis, including p-values, was performed to compare patient characteristics between the two groups. Results: Patients in the radiotherapy group were significantly older than those in the bone modifying agent use group (66 years vs. 56.9 years, p=0.001). There was a higher proportion of males in the radiotherapy group compared to the bone modifying agent use group (90% vs. 22%, p<0.001). Jaw involvement was more prevalent in the radiotherapy group compared to the bone modifying agent use group (95% vs. 66%, p=0.018). Histological analysis showed a similar frequency of Actinomyces species in both groups (50% vs. 34%, p=0.264). Conclusions: The findings of this study suggest the existence of two distinct patient profiles based on their treatment history (bone modifying agent use vs. radiotherapy) in ONJ. Patients in the radiotherapy group were older, predominantly male, and exhibited a higher prevalence of jaw involvement. Histological analysis revealed no significant differences in Actinomyces species frequency between the two groups. These distinct patient profiles may indicate different responses to treatment, emphasizing the need for individualized treatment strategies tailored to specific patient characteristics. Further research is warranted to validate these findings and develop personalized approaches for managing ONJ.
RESUMEN
Introduction: Although Helicobacter pylori's role in gastric oncogenesis is well-known, only a fraction of infected patients develop cancer. Hence, more factors are supposed to be involved. The objectives of the present study were to investigate the impact of clinicopathological parameters on Helicobacter pylori status. Methods: The study included 1522 patients referred for endoscopy: study group consisted of 557 patients with Helicobacter pylori-positive biopsies confirmed using histochemical stains or immunohistochemistry methods; and the control group consisted of 965 patients with Helicobacter pylori-negative status on histology. Results: Severe endoscopic lesions were more frequent in the Helicobacter pylori group (p < 0.001), with no difference noticed in the distribution of premalignant gastric lesions (p = 0.82). Anemia and dyslipidemia were independent factors associated with Helicobacter pylori-positive biopsies (p < 0.05). Non-steroidal anti-inflammatory therapy was more frequently administered in the study group, while proton-pump inhibitors had an anti-Helicobacter pylori activity on histology (p < 0.0001). Conclusion: In the studied population, patients with Helicobacter pylori-positive biopsies had a more frequent history of gastrotoxic medication, severe endoscopic lesions, and anemia. Helicobacter pylori was unpredictable by gastrointestinal symptoms. The frequency of premalignant gastric lesions was similar irrespective of the actual status of infection, underlining the importance of unintentional clearance of bacteria in old infection and the remaining risk for cancer in this population.
RESUMEN
INTRODUCTION: Helicobacter pylori infection is accepted as the leading cause of chronic gastritis, ulcer disease and gastric cancer, with an important impact on health care burden, especially in countries with a high prevalence of infection. The aim of the study was to investigate the influence of H. pylori infection, medication, associated medical conditions or social habits on endoscopic ulcer occurrence in the compensated type 2 diabetic population. MATERIAL AND METHODS: Two hundred and sixty type 2 diabetic patients investigated on endoscopy (57 patients with peptic ulcer and 203 controls) with a complete set of biopsies, demographic and medical data were enrolled. RESULTS: On univariate regression analysis, H. pylori infection (42.1% vs. 35.5%, p = 0.359) or a history of peptic ulcer (61.4% vs. 61.6%, p = 0.981) was not a predictor for ulcer on endoscopy in the diabetic population, and heartburn was more frequent in diabetics without ulcer (21.2% vs. 8.8%, p = 0.033). Anemia was the best predictor for ulcer on endoscopy in both diabetics with (p < 0.001, OR = 4.77, 95% CI: 2.02-11.28) and without (p = 0.027, OR = 2.76, 95% CI: 1.10-6.91) chronic proton pump inhibitor (PPI) therapy. In diabetic patients on PPI more than 1 month anticoagulants - acenocoumarol or low-weight molecular heparin (p = 0.038, OR = 2.37, 95% CI: 1.04-5.40), low-dose aspirin 75-125 mg/day (p = 0.029, OR = 2.61, 95% CI: 1.08-6.28) and alcohol consumption (p = 0.015, OR = 2.70, 95% CI: 1.19-6.13) were predictors for ulcer on endoscopy. CONCLUSIONS: In diabetic patients, anemia is the most important predictor for ulcer on endoscopy, but not H. pylori or digestive symptoms, while low-dose aspirin or anticoagulant therapy and alcohol consumption are the most important predictors for ulcer in diabetics on chronic proton pump inhibitor therapy.
RESUMEN
RATIONALE: Gastric neuroendocrine neoplasms (g-NENs) represent a distinctive group of gastric tumors, stratified into different prognostic categories according to different histological characteristics, put forth in the 2018 World Health Organization classification system. The clinical presentations, as well as pathological features, represent important data in establishing the type of the tumor, in estimating the tumor behavior, and in selecting the best therapeutic strategy. In our case series we presented different clinical scenarios that may be encountered in practice regarding gastric NENs. We performed a literature review and discussed diagnostic strategy, current classification system, precursor lesions, and therapeutic options in g-NENs. PATIENT CONCERNS: The first patient was a 41-year-old female with weight loss, persistent dyspeptic complaints and a history of pernicious anemia. In the second clinical case a 61-year-old man was admitted with heartburn, abdominal pain, diarrhea and mild iron deficiency anemia. The third patient was a 56-year-old male with a history of neoplasia, admitted for weight loss, dyspeptic complaints, and liver metastases. DIAGNOSIS: All the 3 patients underwent upper endoscopy with targeted biopsies. Histopathological and laboratory evaluation, together with imagistic evaluation (abdominal ultrasound, endoscopic ultrasound, and magnetic resonance imaging) allowed the distinction between 3 different types of gastric tumors: type 1 enterochromaffin-like-cell G1 NET, type 2 enterochromaffin-like-cell G2 NET, and type 3 G2 NET with liver metastases. INTERVENTIONS: Endoscopic polypectomy of the largest lesion was performed in patient with type 1 g-NET and autoimmune chronic atrophic gastritis, followed by regular endoscopic surveillance with biopsies. In type 2 g-NET associated with pancreatic gastrinoma, pancreaticoduodenectomy with total gastrectomy were performed. In type 3 g-NET, detected in metastatic stage, oncologic therapy was performed. OUTCOMES: The patients follow-up was selected according to tumor behavior, from regular endoscopic surveillance to oncology follow-up. The prognosis was good in case 1, whilst poorer outcomes were associated with more aggressive tumors in case 2 and case 3. LESSONS: g-NENs are rare tumors with distinct clinical and histological features. Our case series emphasized the role of close collaboration between clinician and pathologist, as well as the importance of a detailed pathology report.

Carcinosarcoma, also known as malignant mixed Müllerian tumor (MMMT), includes both malignant epithelial and mesenchymal elements. While the endometrium is the most frequent known site for carcinosarcomas, their development in the fallopian tube is rare condition, only accounting for 0.1 to 0.5% among all gynecological malignancies. Fallopian tube MMMT is associated with an aggressive progression. A total of 94 previous case reports were reviewed and divided, after applying the exclusion criteria, into 2 groups: No evidence of disease (NED) Group including 33 patients reported to be without any residual disease at the end of the follow-up period; death of disease (DOD) Group including 51 patients who died due to the progression of fallopian carcinosarcoma or its complications. The gathered data were statistically analyzed together with a case from our clinical experience: a 65-year-old postmenopausal patient with a final histological diagnosis of fallopian carcinosarcoma staged FIGO IC2, synchronous with a serous endometrial intraepithelial carcinoma. Patient age between 41 and 60 years, symptoms at presentation and computed tomography (CT)/magnetic resonance imaging (MRI) tumor evidence are prognostic factors (P<0.05). Omentectomy [odds ratio (OR)=0.3545] and pelvic lymphadenectomy (OR=0.3732) were found to be significant factors for survival (P<0.05). Fimbrial localization of the tumor is a negative prognosis factor (OR=4.263), as well as the heterologous type of tumor (OR=2.880). Chemotherapy was found to improve survival (OR=0.2679) while radiotherapy had no influence on patient prognosis. Reporting these rare cases could be essential for obtaining more precise information regarding the treatment and prognosis of patients with MMMT of the fallopian tube, in order to improve patient survival and quality of life.
RESUMEN
ABSTRACT: The study aimed to assess demographic, clinical, and endoscopic parameters in patients with predominant corporeal atrophic gastritis (CAG) and enterochromaffin-like cell hyperplasia suggestive for autoimmune etiology in comparison with patients presenting Helicobacter pylori atrophic gastritis limited to the gastric antrum (AAG).Demographical, clinical, and pathological data of consecutive patients who underwent an upper digestive endoscopy for bleeding screening risk, symptoms, or anemia in a single endoscopy unit were retrieved. The final study group included 63 patients with CAG and enterochromaffin-like cell hyperplasia on histology and a control group of 142 patients with AAG.Female patients were predominant in the group with CAG versus AAG (69.8% vs 46.4%, Pâ=â.002). Microcytic anemia (Pâ<â.001), but not macrocytic anemia (Pâ=â.14) was associated with CAG, the mean corpuscular volume of erythrocyte (MCV) (82.5 vs 86.5âfl, Pâ=â.01), the mean value of serum iron (11.8 vs 14.3âµmol/L, Pâ=â.02), and hemoglobin level (11.0 vs 12.7âg/dL Pâ<â.01) being significantly lower in patients with CAG versus AAG. Upper digestive endoscopies with no visible mucosal lesions (Pâ=â.01) were also more frequent in the patients with CAG, but there were not differences regarding digestive symptoms between groups. The linear regression models revealed that the low hemoglobin (Pâ<â.001) and low MCV (Pâ=â.03) are the independent variables that can predict CAG on histology, but not the serum iron level (Pâ=â.77)Consecutive patients investigated on endoscopy with CAG in comparison with those having AAG are more frequent female, they have microcytic anemia, and no mucosal lesions on endoscopy. The decreased hemoglobin level and low MCV, rather than the serum iron level are predictors for CAG versus AAG on histology in endoscopic population.

BACKGROUND: Innate immunity was found to be associated with both persistence of Helicobacter pylori (H. pylori) infection and increased risk of gastric cancer. AIM: To identify the risk factors associated with H. pylori infection and to establish the role of TLR9 rs352140 in suppressing or promoting inflammation related to this infection in children. METHODS: We performed a study of 155 children with digestive symptoms, who were divided into two groups according to the histopathological exam: Group 1 - 48 children with H. pylori-induced chronic gastritis, and Group 2 - control group. RESULTS: Rural area and poor living conditions were significantly associated with H. pylori chronic gastritis (P = 0.0042/P < 0.0001). Both positive immunoglobulin A anti H. pylori and the rapid urease test were significantly associated with H. pylori infection (P < 0.0001). Significantly higher values of leukocytes and neutrophils within the peripheral blood were found in children with H. pylori chronic gastritis (P = 0.111/P = 0.284). We found a significant positive correlation between the variant TT genotype of TLR9 rs352140 polymorphism and both leucocytes and neutrophils (P = 0.0225/P = 0.0292). CONCLUSION: Variant TT genotype carriers of the TLR9 rs352140 gene polymorphism might have a more severe degree of inflammation.
RESUMEN
Background: Cytokines and their gene variants are proven to play a role in pathogenic gastritis and carcinogenesis. The study assesses associations of the cytokine gene polymorphisms with extension of atrophic gastritis/intestinal metaplasia (AGIM) in patients without Helicobacter pylori infection on immunohistochemistry study. Methods: 224 adult consecutive patients undergoing an upper digestive endoscopy were included and grouped according to localization of AGIM: 37 patients with antrum-limited AGIM, 21 corpus-limited AGIM, 15 extended-AGIM (antrum and corpus) and 151 patients had no AGIM. Medical records of the patients were checked and a structured direct interview was applied in order to collect clinical data, including digestive symptoms. In all cases, IFN-γ +874T>A, TGF-ß1 +869T>C, TNF-α-308G>A and -238G>A, and IL-6 -174C>G polymorphisms were genotyped. Results: The mean age was significantly higher in the AGIM group, while the comorbidies were similar among patients with different localization of lesions or in patients without AGIM. There were no significant differences in digestive symptoms, nor in the consumption of non-steroidal anti-inflammatory drugs or proton pump inhibitor with the different extensions of AGIM. There was a significant association between oral anticoagulant consumption and localization of AGIM (P = 0.042), frequency being higher among patients with corpus-limited AGIM than those with no AGIM (P = 0.007, adjusted P = 0.041). TGF-ß1 +869T>C was less frequent among patients with corpus-limited AGIM (n=7, 33.3%) and extended AGIM (n=5, 33.3%) than in antrum-limited AGIM (n=25, 67.6%). There were no other significant differences regarding variant and wild genotype frequencies of IFN-γ +874T>A (86.5%, 81.0%, 86.7%, p=0.814), TNF-α-308G>A (35.1%, 28.6%, 53.3%, p=0.48) and IL-6 -174C>G (70.3%. 61.9%, 73.3% p=0.656) among patients with antrum-limited, corpus-limited or extended AGIM. TGF-ß1 +869T>C was associated with a decreased risk for corpus-affected AGIM (adjusted odds ratio: 0.42, 95% confidence interval: 0.19-0.93, P = 0.032). The dominant inheritance models no revealed significant association for IFN-γ +874T>A, TNF-α-308G>A and IL-6 -174C>G gene polymorphism and the risk of localization of AGIM. Conclusion: TGF-ß1 +869T>C gene polymorphism is associated with a decreased risk for corporeal localization of premalignant lesions, while IFN-γ +874T>A, TNF-α-308G>A and IL-6 -174C>G are not associated with the risk for AGIM in immunohistochemically H. pylori negative patients.

Helicobacter (H.) pylori infection and duodenogastric reflux (DGR) are both linked to endoscopic and premalignant gastric lesion development, but it is still unclear whether they are independent or have a causal relationship. This study investigated the histologic gastric changes in patients with primary DGR and H. pylori infection, as well as their endoscopic findings, symptoms, drug consumption, and social behavior in comparison with patients presenting only DGR. The study included 560 patients with primary DGR on endoscopy divided into two groups, according to the presence/absence of H. pylori infection on biopsy (utilizing usual stainings and immunohistochemical methods). There was no significant difference in terms of age and sex, nor in the frequency of diabetes or esophagitis between the studied groups. Epigastric pain was associated with H. pylori-positive biopsies in multivariate logistic regression analysis (P=0.005). Although without statistical significance, severe endoscopic lesions and premalignant gastric lesions were more frequent in the H. pylori group (45.1 vs. 28.4% and 37.4 vs. 32.3%, respectively). In patients with DGR, the final multivariate model revealed a positive association between smoking and immunohistochemically confirmed H. pylori infection (P=0.02, OR=1.88, 95% confidence intervals (CI)=1.10 to 3.21), but a negative effect of proton pump inhibitor consumption (P<0.001, OR=0.50, 95% CI=0.35 to 0.73). In conclusion, in patients with H. pylori infection and DGR, epigastric pain was the main reason for the endoscopic investigation. H. pylori infection over DGR did not influence the severity of endoscopic or premalignant gastric lesion development. Furthermore, smoking is directly related to immunohistochemically assessed active H. pylori infection in patients with bile reflux.
RESUMEN
Non-invasive biomarkers, such as neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios, may predict inflammation in various disorders, including gastritis, according to recent data. Nevertheless, various studies reported an association between Helicobacter pylori (H pylori) and immune thrombocytopenia in both adults and pediatric patients. The objective of our study was to evaluate the impact of pediatric gastritis, caused or not by H pylori infection on erythrocytes, their parameters, thrombocytes, mean platelet volume, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR).We performed a prospective, case-control study on 151 patients aged between 1 and 17 years who presented with chronic dyspeptic symptoms. An upper digestive endoscopy with gastric biopsies and a complete blood count was performed in each case.Control group consisted of 67 patients with normal histological findings, while the two study groups were divided into group 1-H pylori-induced gastritis (31 patients) and group 2-non-H pylori-induced gastritis (53 patients). Children from the rural area were more likely to develop both types of gastritis (Pâ<â.01). No significant difference was found between either of the study groups and control group in terms of platelets, mean platelet volume, NLR and PLR (Pâ>â.05). However, significantly higher values of lymphocytes were associated with non-H pylori-induced gastritis (Pâ<â.01). Comparison of the two study groups did not reflect any significant differences in terms of hematological parameters. When assessing these constants in relation to gastritis severity, severe gastritis led to a compelling decrease in hemoglobin (Hb) and hematocrit (Htc) levels. The comparison of parameters between severe, moderate, and mild gastritis did not reveal any significant results.Childhood and adolescent gastritis does not produce a significant effect upon platelet counts, their mean volume, PLR or NLR, according to our study. An important increase in lymphocyte count might predict non-H pylori pediatric gastritis. Moreover, severe gastritis might result in an important decrease in Hb and Htc levels.

BACKGROUND AND AIMS: The importance of sessile serrated lesions (SSLs) in the pathogenesis of colorectal carcinoma has been recently established. These are supposed to cause the so-called "interval cancer", having a rapidly progressive growth and being difficult to detect and to obtain an endoscopic complete resection. We aimed to establish the most important metabolic risk factors for sessile serrated lesions. METHODS: We performed a retrospective case-control study, on a series of 2918 consecutive patients who underwent colonoscopy in Gastroenterology and Endoscopy Unit, County Clinical Emergency Hospital, Târgu-MureÈ, Romania between 1 st of January 2015-31 th of December 2017. In order to evaluate the metabolic risk factors for polyps' development, enrolled participants were stratified in two groups, a study group, 33 patients with SSLs lesions, and a control group, 138 patients with adenomatous polyps, selected by systematic sampling for age and anatomical site. Independent variables investigated were: gender, smoking, alcohol consumption, obesity, arterial hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia, hyperuricemia, nonalcoholic liver disease. RESULTS: For SSLs the most common encountered localization was the right colon in 30.55% of cases. By comparative bivariate analysis between SSLs group and control group, it was observed that hypertension (p=0.03, OR 2.33, 95 %CI 1.03-5.24), obesity (p=0.03, OR 2.61, 95 %CI 1.08-6.30), hyperuricemia (p=0.04, OR 2.72, 95 %CI 1.28-7.55), high cholesterol (p=0.002, OR 3.42; 95 %CI 1.48-7.87), and high triglycerides level (p=0.0006, OR 5.75; 95 %CI 1.92-17.2) were statistically associated with SSLs development. By multivariate analysis hypertension and hypertriglyceridemia retained statistical significance. CONCLUSIONS: Our study showed that the highest prevalence of SSLs was in the right colon and hypertension and increased triglycerides levels were associated with the risk of SSLs development. These risk factors are easy to detect in clinical practice and may help identifying groups with high risk for colorectal cancer, where screening is recommended.

Inflammatory and nasal-sinus tumor pathology is a field of great interest in rhinology worldwide. The aim of the paper is to determine the prevalence of nasal and nasal-sinus inflammatory diseases, as well as nasal and nasosinusal rhinosinusitis tumors, in association or not with inflammatory diseases, using histopathological (HP) examination. It is also desired to identify the association of chronic inflammatory pathology with the tumor one, considering inflammation and immunodeficiency as local susceptibility factors. A retrospective study was performed on a group of 254 patients hospitalized between 2018-2019 in Department of Otorhinolaryngology, Emergency County Hospital, Târgu Mures, Romania. Based on the clinical and HP examination, the distribution by inflammatory pathologies was made as follows: 175 nasal polyposis, 108 chronic rhinitis, 39 sinusitis - strictly affecting the sinus and 28 chronic polyposis rhinosinusitis - nasal and sinus association. Considering the evaluation of the incidence of benign tumor pathology, the following were found: out of the total examined cases, 4% squamous papilloma, 4% exophytic papilloma, 44% Schneiderian papilloma, 4% benign fibrous histiocytoma, 18% hemangioma, 4% hamartoma, and 4% osteoma were identified. The incidence of malignant tumors is 26% squamous cell carcinoma, 12% intestinal adenocarcinoma, 2% nonintestinal type adenocarcinoma, 2% large B-cell lymphoma, 2% plasma cell, 2% olfactory neuroblastoma, 7% malignant melanoma, 16% basal cell carcinoma. The paper draws attention to the increased incidence of tumor and inflammatory pathology both individually and in combination, considering the involvement of the clinical correlation with the HP result completed, if necessary, with immunohistochemical examinations, for a precise diagnosis.

BACKGROUND: TLR4 is involved in H. pylori lipopolysaccharide recognition and its SNPs might be related to increased risk of developing premalignant conditions and gastric cancer. The objectives of the study were to evaluate the associations between both TLR4 rs4986790 and rs4986791 gene polymorphisms and H. pylori infection in children with gastritis. METHODS: We performed a cross-sectional study on 150 children admitted in a Tertiary Centre from Romania, between March 2016 and July 2018 in order to evaluate them regarding demographic, endoscopic, histopathological and TLR4 gene polymorphisms. RESULTS: Our final sample consisted of 50 children with H.pylori associated gastritis (group 1-Ghp group) and 97 children with gastritis without H.pylori infection (group 2). Poor socioeconomic status was a significant risk factor for H.pylori infection. We found no significant differences regarding the clinical symptoms and laboratory parameters between the two groups. Concordant results were found between the histopathological exam and rapid urease test. Variant genotypes of TLR4rs4986790 and TLR4rs4986791 gene polymorphisms acted as protective factors against H. pylori infection, without statistical significance. CONCLUSIONS: The variant genotype of the TLR4 gene polymorphisms might be protective factors for H.pylori infection, while socioeconomic status is an risk factor for H. pylori infection. Urease test is a usefull diagnostic tool for H. pylori infection.

Neutrophil to lymphocyte ratio (NLR) is a simple, noninvasive, inexpensive inflammatory marker that can useful in the assessment of inflammatory activity, especially in pediatric ages. The aim of our study was to establish correlations between the presence of Helicobacter pylori (HP) proved histologically and NLR in children.A prospective, case-control study was performed on 137 pediatric patients aged between 1 and 18 years, admitted in a Pediatric Tertiary Hospital from Romania, between April 2016 and January 2018. According to the histologic examination, the children were divided into 2 groups: group 1: 50 children with HP infection, and group 2: 87 children without any pathologic findings.The mean age for the study group was 12.86â±â3.796 years, whereas for control group, it was 12.10â±â3.879 years (Pâ=â.3001). HP infection was significantly more frequent among children from rural area (Pâ=â.0089). Epigastric pain and loss of appetite were significantly associated with HP infection (Pâ=â.0350â/Pâ=â.0281). We noticed that the leukocyte and neutrophil counts were significantly higher in group 1 (Pâ=â.0076/Pâ=â.0306). We did not find any significant statistical differences between the 2 groups in terms of lymphocytes, erythrocyte sedimentation rate, and NLR or other assessed laboratory parameters. Regarding the IgA antibodies anti-HP and rapid urease test, they were both significantly associated with histologically confirmed HP infection (Pâ<â.0001).Even though, we did not identify significant differences in term of NLR between HP-induced gastritis children and healthy controls, the mean NLR values were higher HP-positive patients.

RATIONALE: Herpetic esophagitis (HE) is a common condition in immunosuppressed patients, but a rare entity in immunocompetent patients affecting especially male teenagers and young adults. PATIENT CONCERNS: We report the case of a 5-year-old male patient, with a history of allergic rhinitis admitted in our clinic for acute onset fever refractory to antipyretics, chest pain, anorexia, refusal of solid food, accepting only small amounts of fluids, odynophagia, and epigastric pain. The clinical exam revealed severe malaise, pallor, decreased skin turgor, abdominal epigastric tenderness, heartburn at palpation within the epigastric area. The laboratory tests showed leukocytosis, monocytosis, hypoglycaemia, and elevated inflammatory biomarkers. DIAGNOSES: The serology tests for human immunodeficiency virus (HIV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), and herpes simplex virus (HSV) were negative, except for immunoglobulin G (IgG) anti-EBV which was positive. The chest radiography was normal, and the abdominal ultrasound showed abdominal bloating. The upper digestive endoscopy revealed friable esophageal mucosa, with multiple ulceration on the entire esophagus, and whitish exudates especially on the middle and lower part of the esophagus suggesting a possible eosinophilic esophagitis or caused by Candida. Despite the empirical initiated treatment, the patient's evolution was only slowly favorable. The histological exam established the diagnosis of HE. INTERVENTIONS: We initiated acyclovir therapy with an outstandingly favorable evolution. OUTCOMES: After 1 month, we detected the seroconversion of IgG anti-HSV. The patient's follow-up revealed no additional complaints. LESSONS: Despite its rarity in immunocompetent individuals, HE must be taken into account even in otherwise healthy small children.

AIM: We aimed to establish the independent predictive factors (from Helicobacter pylori infection, biliary reflux, histologic features of the gastric mucosa, drugs, comorbidities, and social habits) for gastric stump ulcer occurrence more than 15 years after surgery. METHODS: 76 patients with previous gastric surgery were included: 21 patients with gastric ulcer (marginal ulcer or ulcer of the rest of the gastric remnant-study group) and 55 controls (nonulcer group). RESULTS: Helicobacter pylori infection tended to be higher in the control group than in the ulcer group (14.5% vs. 4.8%, p = 0.43), without statistical significance. Alcohol consumption had a significant positive association with ulcer (p = 0.008), while smoking (p = 0.064), low-dose aspirin (p = 0.063), and biliary reflux (p = 0.106) had a tendency toward statistical signification for positive association. On univariate analysis, smoking (p = 0.048, OR = 3.15, 95% CI: 1.01-9.93) and low-dose aspirin consumption (p = 0.067, OR = 2.63, 95% CI: 0.95-7.68) were significantly associated with ulcer. According to the multivariable regression model, alcohol consumption (OR = 6.68, 95% CI: 1.29-41.14) and biliary reflux (OR = 6.12, 95% CI: 1.36-38.26) remained significantly associated with increased odds of stump ulcer. CONCLUSION: Biliary reflux and alcohol consumption, but not Helicobacter pylori infection or gastrotoxic drug, seem to be the most important predictors for ulcer recurrence in patients with gastric surgery for peptic ulcer after more than 15 years.
RESUMEN
BACKGROUND AND AIMS: The increased oxidative stress plays an important role in gastro-duodenal ulcers and gastric cancer occurrence. We investigated the association between the genetic polymorphisms of genes encoding the antioxidative enzymes CAT, GPX and SOD and the occurrence of gastric lesions, considering also the environmental risk factors such as H. pylori infection, drug exposure, smoking and alcohol consumption. METHODS: We included 373 patients who underwent endoscopy for symptoms, anemia or bleeding investigation. A complete set of demographical, clinical and pathological data was recorded. All patients were successfully genotyped. RESULTS: In the multivariate logistic regression model, the patients having Pro/Pro genotype of GPX1 gene polymorphism had more severe gastric lesions as compared with patients with the Leu/Pro or Leu/Leu genotype (OR= 1.89, 95%CI: 0.99-3.57, p=0.051). The GPX1 Pro198Leu and the MnSOD Ala16Val gene polymorphism could be independent risk factors for reactive gastropathy changes, as shown by their association very close to statistical significance (p=0.059 and p=0.054, respectively). Consumption of anticoagulants was a significant independent predictor (p=0.023, OR:0.43 95%CI:0.21-0.89) for the absence of active gastritis, while low-dose aspirin consumption was a risk factor for active gastritis in biopsy samples (p=0.025, OR:1.71, 95%CI:1.07-2.74). CONCLUSION: The variant genotype of GPX1Pro198Leu was associated with an increased risk for reactive gastropathy changes in gastric biopsies and with less severe endoscopic lesions, while MnSODAla16Val variant genotype (Val/Val or Val/Ala) seems to be related to the reactive gastropathy. However, none of them were associated with inflammatory or premalignant gastric lesions.

Experimental studies showed a dose-dependent gastroprotective effect of statins on non-steroidal anti-inflammatory drug-induced endoscopic lesions, modulated by increasing endogenous nitric oxide and prostaglandin production.We investigated the influence of chronic treatment with statins on the occurrence of endoscopic lesions in patients referred for endoscopic evaluation, adjusted for the most important etiologic and risk factors for peptic ulcer disease and its complications.A consecutive series of 564 patients who underwent upper digestive endoscopy, stratified according to the severity of endoscopic lesions were recruited. Patients with statin therapy were included in the study group (nâ=â220), while patients without statins in the control group (nâ=â344). We correlate the influence of chronic statin therapy (at least 6 months) with factors including age up to 50 years, Helicobacter pylori infection, smoking and drinking habits, ulcer history, gastrotoxic drug consumption (low-dose aspirin [ASA], anticoagulants), and comorbidities.H pylori infection was more frequent in patients with mild/severe endoscopic lesions vs. no lesions, in both groups, but the difference was not statistically significant (Pâ>.05). Male gender represented a risk factor (Pâ<.01) for mild/severe endoscopic lesions only in the statin group. The estimated risk for developing mild/severe endoscopic lesions with ASA intake decreased from 6.26 to 3.40 (Pâ<.01) when statin therapy was associated. Patients without statins and ischemic coronary artery disease (Pâ<.01; odds ratio [OR]â=â2.99; 95% confidence interval (CI):1.88-4.73), heart failure (Pâ=â.01; ORâ=â2.13; 95% CI:1.36-3.34), systemic atherosclerosis (Pâ=â.04; ORâ=â2.30; 95% CI:1.44-3.67) had a statistically significant increased risk for developing mild/severe endoscopic lesions in comparison with patients in the statin group. In multivariate regression analysis models, smoking (Pâ<.01; ORâ=â2.69; 95% CI:1.73-4.16), ASA (Pâ<.01; ORâ=â4.54; 95% CI:2.83-7.16), and coronary artery diseases (Pâ=â.01; ORâ=â1.80; 95% CI:1.15-2.82) were independent risk factors for mild/severe endoscopic lesions, while chronic statin therapy (Pâ<.01; ORâ=â0.31; 95% CI:0.19-0.51) was associated with a protective effect in all models.The results of the present study support a certain protective role of chronic therapy with statins against endoscopic lesions, especially in ASA consumers or patients with cardiovascular diseases.

BACKGROUND AND AIMS: The pathogenesis of gastric cancer involves premalignant changes of the gastric mucosa. An accurate estimation of the topography and severity of these lesions represents an important step in detecting premalignant lesions, thereby classifying patients into low or high risk of developing gastric cancer. We prospectively analyzed the diagnostic performance of narrow-band imaging with magnification endoscopy (NBI-ME) for assessing premalignant gastric lesions during real-time examination. PATIENTS, MATERIALS AND METHODS: A total number of 59 patients were examined by NBI-ME and target biopsies of the antrum, corporeal, and incisura angularis levels. Modified endoscopic patterns were classified into three groups: type A [tubulo-villous mucosal pattern with regular microvessels, or the light blue crest (LBC) sign], type B [disappearance of normal subepithelial capillary network (SECN) pattern], and type C [irregular mucosal pattern (IMP) and∕or irregular vascular pattern (IVP)]. The endoscopic diagnosis was compared to histological findings (the gold standard). The NBI-ME results were assessed for accuracy, sensitivity, specificity, and negative and positive predictive values in detecting intestinal metaplasia, atrophic gastritis and dysplasia. RESULTS: Analysis of endoscopic patterns showed a good correlation with premalignant lesions (p<0.05). Type A pattern showed 80.2% accuracy, 80.43% sensitivity and 80% specificity [area under receiver operating characteristic (AUROC) of 0.8] in detecting intestinal metaplasia. Diagnostic performance for assessment of atrophic gastritis was not ideal (69.5% accuracy, 83.72% sensitivity, 56.04% specificity, AUROC 0.69). Pattern C represents a reliable endoscopic marker for the diagnosis of dysplasia (91.1% accuracy, 83.3% sensitivity, 91.81% specificity, AUROC 0.87). The extension of precancerous lesions was estimated during endoscopic examination. CONCLUSIONS: NBI-ME represents a valuable tool in the assessment of premalignant gastric lesions, thereby categorizing patients into low and high risks of developing gastric cancer. The applicability of the method in routine practice is promising, as it helps shape the follow up protocol of patients with premalignant lesions of the stomach. It is worth mentioning that, this method requires standardization, additional training, and expertise.
