Foreign body ingestion is a frequently encountered emergency in healthcare institutions. It mostly affects pediatric populations, although it can also affect adults with developmental delays, those with psychiatric diseases, drug abusers, and prisoners. Endoscopy is a diagnostic and treatment method for suspected foreign body ingestion. In this article, we discuss a 45-year-old tailor who swallowed a sewing pin while at work. The abdominal X-ray showed a needle-shaped metal shadow in the stomach region. During an upper endoscopy, it was discovered that a sewing pin with a sharp edge was stuck in the pylorus. The sewing pin was extracted endoscopically, and the patient was discharged the same day in good condition. Since the estimated risk of complications of foreign body ingestion in the adult population is about 35%, and the most common complications include impaction, laceration, bleeding, or perforation of the gastrointestinal wall, endoscopic or surgical removal is necessary. This also emphasizes the importance of a careful endoscopic evaluation of some at-risk occupations for foreign body ingestion with or without gastrointestinal complaints. © 2023 by the authors.

Background: The increasing incidence of duodenal neoplasm has underlined different methods of resection depending on the clinical presentation, endoscopic features and histopathology. In this comprehensive review, we systematically describe the current knowledge concerning the diagnosis and management of duodenal adenomas (DAs) and discuss data considering all possible therapeutic approaches. Summary: Among a variety of duodenal lesions, including neuroendocrine tumors and gastrointestinal stromal tumors, DAs present precancerous lesions of the duodenal papilla or non-ampullary region necessitating removal. DAs can occur sporadically (SDA) as rare lesions or relatively common in polyposis syndromes. The endoscopic resections of DA are associated with an increased degree of complexity due to distinctive anatomical properties of the duodenal wall, luminal diameter and the presence of ampulla with pancreatic and biliary drainage. The endoscopic techniques including cold snare polypectomy (CSP), endoscopic mucosal resection (EMR), and argon plasma coagulation ablation are suggested to be less invasive than surgical treatment, associated with shorter hospital stay and lower cost. According to the current clinical practice, surgery has been accepted as standard therapeutic approach in familial adenomatous polyposis patients with severe polyposis or DA not amenable to endoscopic resection. Key Messages: The strategy for endoscopic resection of DAs depends on the lesion size, morphology, location, and histopathology findings. Small adenomas are most frequently diagnosed and removed by standard CSP techniques, while large laterally spreading lesions and ampullary adenoma are referred for EMR or endoscopic papillectomy respectively. Screening colonoscopy is indicated in patients with SDA. Additional studies for new endoscopic strategies and techniques for curative therapy of DAs are needed to refine future management decisions. Complete resection of DA is considered curative, but nevertheless, long-term endoscopic follow-up is still required to detect and treat any recurrent arising lesions. © 2018 S. Karger AG, Basel.

Background: Systemic inflammation in colorectal cancer (CRC) may be reflected by neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV). This study was designed to investigate the efficiency of preoperative NLR, PLR, and MVP as a tool for the assessment of tumor characteristics in newly diagnosed patients with CRC. Patients and Methods: For 300 patients and 300 healthy volunteers, complete blood counts with automated differential counts were performed. The NLR was calculated by dividing the absolute neutrophil count by the absolute lymphocyte count; PLR was calculated by dividing the absolute platelet count by the absolute lymphocyte count. The diagnostic performance of NLR, PLR, and MVP was estimated by ROC curve. Results: ROC curve analysis showed high diagnostic efficacy of NLR and PLR in CRC patients with cut-off values of 2.15 (AUC = 0.790, 95% CI 0.736-0.884, Se = 74.1%, and Sp = 73%) and 123 (AUC = 0.846, 95% CI 0.801-0.891, Se = 73.5%, and Sp = 80%) compared to healthy controls, respectively. The diagnostic efficacy of three combined markers was superior compared with individual markers (AUC = 0.904, 95% CI 0.812-0.989, Se = 96%, and Sp = 70%). Conclusion: NRL, PLR, and MPV may be useful markers in diagnostic and early recognition of different stages of CRC; additionally combined all together have stronger diagnostic efficacy.

There is no universally accepted treatment for severe pediatric alopecia areata (AA). This prospective study comprised 73 patients (aged 1–18 years) with severe AA (>30% of scalp surface area): 37 received 1-day intravenous dexamethasone pulses (1-DP) and 36 received 3-day pulses (3-DP), monthly, for 6–12 months. Also, all patients applied topical clobetasol propionate under plastic wrap occlusion. Patients achieving >50% regrowth were considered good responders (GR). All patients reached short term, while 65/73 were available for the long-term follow-up (mean 33.3 ± 15.3 vs. 27.7 ± 14.3 months, 1-DP and 3-DP, respectively). Relapses during therapy were more frequent in 1-DP group. 3-DP patients were more frequently GR in comparison with 1-DP. 3-DP patients with disease duration <6 months had better outcomes. Patients without Hashimoto thyroiditis (HT) had 9.8-fold higher chance of being GR in comparison with HT patients. The best results were achieved in AA plurifocalis (AAP). No patient had severe short-term side-effects. At the long-term follow-up, 67% of 3-DP patients had stable results. Only 14.2% AAP patients experienced relapses. Patients had no long-term side-effects. 3-DP were more efficacious than 1-DP. Short disease duration and no HT were good prognostic factors. 3-DP protocol is well-tolerated, with beneficial effects and long-lasting results in severe pediatric AA. © 2019 Wiley Periodicals, Inc.

Background and Objectives. Determination of inflammatory bowel disease activity determines further therapeutic approach and follow-up. The aim of our study was to investigate correlation between patients' reported symptoms and endoscopic and histological disease activity. Methods. A cross-sectional study was conducted in consecutive newly diagnosed patients with inflammatory bowel disease in a tertiary care referral center. The initial evaluation included patient-reported outcome for stool frequency subscore and rectal bleeding. Endoscopic activity was determined using the Mayo scoring system for ulcerative colitis and the Simple Endoscopic Score for Crohn's disease. Histopathological activity was assessed using a validated numeric scoring system. Results. We included 159 patients (63 Crohn's disease with colonic involvement and 96 with ulcerative colitis). We found significant correlation between the Mayo endoscopic subscoring system and histology activity in ulcerative colitis, while no correlation was found in patients with Crohn's disease. Patient-reported outcome showed inverse correlation with endoscopic and histological activity in Crohn's disease (rs=-0.67; rs=-0.72), while positive correlation was found in ulcerative colitis (rs=0.84; rs=0.75). Interpretation and Conclusions. Patient-reported outcome is a practical and noninvasive tool for assessment of disease activity in ulcerative colitis patients but not in Crohn's disease. © 2020 Sanja Dragasevic et al.

Objective. Keeping in mind the rising prevalence of nonalcoholic fatty liver disease (NAFLD) and the need to establish noninvasive tests for its detection, the aim of our study was to investigate whether platelet count (PC), mean platelet volume (MPV), and platelet distribution width (PDW) can predict the presence of liver fibrosis in this group of patients. Methods. In 98 patients with NAFLD and 60 healthy volunteers, complete blood counts with automated differential counts were performed and values of PC, PDW, MPV, and PCT were analyzed. Results. Patients with NAFLD had lower PC and higher MPV, PCT, and PDW compared to the controls (P < 0.05). When NAFLD group was stratified according to severity of liver fibrosis, there was a statistically significant difference in the average values of PDW and PC between the groups (P < 0.05). Conclusion. Patients with NAFLD have significantly higher values of PCT, PDW, and MPV when compared to the healthy controls. Further studies are needed to establish their potential use for prediction of the degree of liver steatosis and fibrosis in NAFLD patients. © 2017 Tamara Milovanovic Alempijevic et al.

Considering an increase in the life expectancy leading to a rise in the elderly population, it is important to recognize the changes that occur along the process of aging. Gastrointestinal (GI) changes in the elderly are common, and despite some GI disorders being more prevalent in the elderly, there is no GI disease that is limited to this age group. While some changes associated with aging GI system are physiologic, others are pathological and particularly more prevalent among those above age 65 years. This article reviews the most important GI disorders in the elderly that clinicians encounter on a daily basis. We highlight age-related changes of the oral cavity, esophagus, stomach, small and large bowels, and the clinical implications of these changes. We review epidemiology and pathophysiology of common diseases, especially as they relate to clinical manifestation in elderly. Details regarding management of specific disease are discussed in detail if they significantly differ from the management for younger groups or if they are associated with significant challenges due to side effects or polypharmacy. Cancers of GI tract are not included in the scope of this article. © 2019 Igor Dumic et al.

Background and Objectives: Despite improvements in screening programs, a large number of patients with colorectal cancer (CRC) are diagnosed in an advanced disease stage. Previous investigations imply that glutathione transferases (GSTs) might be associated with the development and progression of CRC. Moreover, the detoxification mechanism of oxaliplatin, which represents the first line of treatment for advanced CRC, is mediated via certain GSTs. The aim of this study was to evaluate the significance of certain GST genetic variants on CRC prognosis and the efficacy of oxaliplatin-based treatment. Materials and Methods: This prospective study included 523 patients diagnosed with CRC in the period between 2014 and 2016, at the Digestive Surgery Clinic, University Clinical Center of Serbia, Belgrade. Patients were followed for a median of 43.47 ± 17.01 months (minimum 1–63 months). Additionally, 109 patients with advanced disease, after surgical treatment, received FOLFOX6 treatment as a first-line therapy between 2014 and 2020. The Kaplan–Meier method was used to analyze cumulative survival, and the Cox proportional hazard regression model was used to study the effects of different GST genotypes on overall survival. Results: Individuals with the GSTM1-null genotype and the GSTP1 IleVal+ValVal (variant) genotype had significantly shorter survival when compared to referent genotypes (GSTM1-active and GSTP1 IleIle) (log-rank: p = 0.001). Moreover, individuals with the GSTM1-null genotype who received 5-FU-based treatment had statistically significantly shorter survival when compared to individuals with the GSTM1-active genotype (log-rank: p = 0.05). Conclusions: Both GSTM1-null and GSTP1 IleVal+ValVal (variant) genotypes are associated with significantly shorter survival in CRC patients. What is more, the GSTM1-null genotype is associated with shorter survival in patients receiving FOLOFOX6 treatment. © 2024 by the authors.

Background: Liver cirrhosis is the final stage of chronic liver disease. We aimed to evaluate non-invasive scores as predictors of complications and outcome in cirrhotic patients. Methods: A total of 150 cirrhotic patients were included. Models for end-stage liver disease (MELD), albumin-bilirubin (ALBI) score, neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MoLR), and neutrophil-lymphocyte-albumin ratio (NLA) scores were tested in relation to the development of complications and mortality using receiver operating characteristic (ROC) curves. Results: The ROC curve analysis showed (area under the curve) AUC values of NLR, NLA, ALBI, and MELD of 0.711, 0.730, 0.627, and 0.684, respectively, for short-term mortality. MELD, ALBI, and NLA scores showed a statistically significant correlation with hepatic encephalopathy (p = 0.000 vs. 0.014 vs. 0.040, respectively), and the MELD cut-off value of 16 had a sensitivity of 70% and a specificity of 52% (AUC: 0.671, 95% CI (0.577–0.765)). For the assessment of the presence of ascites, the AUC values for NLA and MoLR were 0.583 and 0.658, respectively, with cut-offs of 11.38 and 0.44. Conclusions: MELD, ALBI, and NLA are reliable predictors of hepatic encephalopathy. NLA and MoLR showed a significant correlation with the presence of ascites, and MELD, ALBI, NLR, and NLA have prognostic value to predict 30-day mortality in cirrhotic patients. © 2023 by the authors.

Background. Ultrasonography is a noninvasive, inexpensive, and widely available diagnostic tool. In the last two decades, the development of ultrasound techniques and equipment has significantly increased the usage of intestine ultrasound (US) in the assessment of the gastrointestinal tract in patients with inflammatory bowel disease (IBD). Although current guidelines suggest routine utilization of US in patients with Crohn's disease, data regarding US usage in ulcerative colitis are still scarce. We aimed to assess the reliability of intestinal ultrasonography in the assessment of disease activity and extension of patients with ulcerative colitis. Methods. Fifty-five patients with a histologically confirmed diagnosis of ulcerative colitis, treated at University Clinical Center of Serbia in the period from 2019 to 2022 were included in this retrospective observational study. The data were obtained from the patient's medical records including history, laboratory, US, and endoscopy findings. US examined parameters were as following: bowel wall thickness (BWT), presence of fat wrapping, wall layer stratification, mesenteric hypertrophy, presence of enlarged mesenteric lymph nodes, and absence or presence of ascites. Results. Our results suggest that there is a strong correlation of BWT and colonoscopy findings regarding disease extension (r = 0.524, p=0.01, p<0.05). Furthermore, our results have shown a statistically significant correlation of BWT with the Mayo endoscopic score (r = 0.434, p=0.01, p<0.05), disease activity score (r = 0.369,p=0.01, p<0.05), degree of ulcerative colitis burden of luminal inflammation (r = 0.366, p=0.01, p<0.05), and Geboes index (r = 0.298, p=0.027, p<0.05). Overall accuracy of US for disease extension and activity was statistically significant (p<0.05). Conclusions. Our results suggest that US is a moderately accurate method for the assessment of disease activity and localization in patients with UC. © 2022 Milica Stojkovic Lalosevic et al.

Background: Jaundice is a common clinical finding in clinical practice of hepatologists and general practitioners. It occurs when serum bilirubin levels exceed 3 mg/dL. Summary: In this review, we summarize the pathophysiological mechanism of jaundice, clinical approach to the patient with jaundice, and laboratory and imaging techniques. Clinical presentation of jaundice manifests through yellow skin and sclera coloration. Evaluation of every patient includes detailed medical history and examination. In the laboratory, evaluation of enzymes of hepatic inflammation as well as cholestatic enzymes with serum bilirubin must be included. Additional laboratory analysis and imaging modalities are needed in order to differentiate jaundice etiology. Moreover, imaging is available and needed in further evaluation, and treatment is dependent on the underlying cause. Key Messages: In this review, we will outline the pathophysiological mechanism of jaundice, clinical approach to the patient with jaundice, and diagnostic and treatment approach to these patients. © 2021 S.

Primary biliary cholangitis (PBC) is a chronic cholestatic autoimmune disease, predominantly affecting middle-aged women, which may progress to end-stage liver disease. We aimed to assess the quality of life (QoL) in patients with PBC given that social, economic, and geographical factor also influence QoL. Methods: This study included patients with diagnosed PBC according to the European Association for the Study of the Liver guidelines, who were treated for at least 6 months in order to allow adequate time for the initial burden of symptoms to subside. We used the PBC-40 questionnaire validated in the Serbian language. Results: The mean total PBC-40 score was 89.4 ± 29.3. The overall frequency of moderate and severe involvement in each domain was as follows: 84.9% (n = 107) in "Symptoms,"29.3% (n = 36) in "Itch,"76.4% (n = 97) in "Fatigue,"58.1% (n = 72) in "Cognitive,"77.2% (n = 98) in "Social,"and 70.9% (n = 90) in "Emotional."There was a statistically significant negative correlation of disease duration and albumin score with the Emotional domain score. Furthermore, this domain showed a significant positive correlation with the Mayo score. Conclusion: The present study demonstrates that patients with PBC have significant impairment in QoL with fatigue being the most prevalent symptom. The Social and Emotional domains were also significantly affected in these individuals, particularly in patients with peripheral edema who exhibited worse QoL that those who were euvolemic. © 2020 S.
