    Abstract 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.

    Abstract 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.

    Abstract 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 Mureş, 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.

    Abstract 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.

    Abstract 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%, P = .002). Microcytic anemia (P < .001), but not macrocytic anemia (P = .14) was associated with CAG, the mean corpuscular volume of erythrocyte (MCV) (82.5 vs 86.5 fl, P = .01), the mean value of serum iron (11.8 vs 14.3 μmol/L, P = .02), and hemoglobin level (11.0 vs 12.7 g/dL P < .01) being significantly lower in patients with CAG versus AAG. Upper digestive endoscopies with no visible mucosal lesions (P = .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 (P < .001) and low MCV (P = .03) are the independent variables that can predict CAG on histology, but not the serum iron level (P = .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.

    Abstract Background: Breast cancer is the female cancer with the highest mortality. While early detection is a public health priority in Western European countries, a screening program in our country has yet to be implemented. The best diagnostic accuracy is achieved through the use of triple assessment: clinical examination, imaging, and core-needle biopsy where indicated. Prognosis is influenced by clinical, histological, and biological factors, and therapy is most effective when individually tailored.
