"Decoding inflammation: glycoprotein a repetition predominant, microRNA-142-3-p, and metastasis associated lung adenocarcinoma transcript 1: as novel inflammatory biomarkers of inflammatory bowel disease".

BACKGROUND: Inflammatory bowel disease (IBD) is a chronic gastrointestinal (GI) condition comprising Crohn's disease (CD) and ulcerative colitis (UC). The pathogenesis involves immune system dysregulation, with increased Th (T helper cell)17 cells and reduced regulatory T cell (Treg) differentiation. Transforming growth factor-ß (TGF-ß) secretion from Tregs helps control inflammation, and its production is regulated by glycoprotein-A repetition predominant (GARP) protein along with non-coding RNAs (ncRNAs) like microRNA(miR)-142-3p and metastasis associated lung adenocarcinoma transcript 1 (MALAT1) long non-coding RNAs (LncRNAs). This study analyzed their expression in IBD. METHODS: Blood samples were collected from 44 IBD patients, and 22 healthy controls (HC). RNA extraction and circular DNA (cDNA) synthesis were performed. Real-time polymerase chain reaction (RT-PCR) measured gene expression of GARP, MALAT1, and miR-142-3p. Correlations and group differences were statistically analyzed. RESULTS: Compared to controls, GARP was downregulated while MALAT1 and miR-142-3p were upregulated significantly in IBD group. GARP and MALAT1 expressions positively correlated in controls. MALAT1 and miR-142-3p expressions positively correlated in IBD group. MALAT1 was downregulated in aged HC but upregulated with smoking history across groups. No correlations occurred between gene expression and gender, diet, infections, or disease activity scores. CONCLUSIONS: Dysregulation of GARP, MALAT1, and miR-142-3p likely contributes to inflammation in IBD by reducing TGF-ß. MALAT1 is linked to smoking and age-related changes. These genes have potential as diagnostic markers or therapeutic targets for personalized IBD treatment.

The role of endoscopic ultrasound in primary pancreatic lymphoma presented with acute pancreatitis: a case report.

CONTEXT: Primary pancreatic lymphoma (PPL) is rare but manageable malignant tumor of the pancreas which may be confused with pancreatic adenocarcinoma. CASE REPORT: We report a 38 year-old smoker man with IVDA and history of B (inactive carrier), C (Ia genotype) hepatitis and negative for HIV admitted to our hospital because of nausea, vomiting, epigastric and RUQ pain as a result of long period of alcohol consumption. Due to high amount of amylase (480 U/L) and lipase (326 U/L) Pancreatitis was diagnosed. Four days after admission CT was done that showed enhancement a large tumor of the head of the pancreas. Endoscopic ultrasound (EU) revealed diffusely enlarged of pancreas. There was a mixed echoic mass lesion 37-50 mm at the head of pancreas (R/O walled off necrosis) with adhesion to portal vein and SMV. On the other hand the CBD was 9 mm. Abdominal MRI and MRCP for patient was done. The intra-hepatic bile ducts, main hepatic ducts, CHD and CBD were mildly dilated and displaced to the right side by a large lobulated mass (160×112×130 mm) of pancreatic head with low signal intensity on T1W images and high intensity on T2W images. we did EUS-FNA and there was a mixed echotic lesion (38-40 mm) adhered to head of pancreas with invasion to portal vein, SMA and SMV. The diagnosis of pancreatic lymphoma was established by immunohistochemical study and the assessment of the neoplastic cells revealed B cell lymphoma phenotypes. CONCLUSION: Herein we present an interesting 38 year- old man with pancreas head tumor. Primary pancreatic lymphoma is almost never suspected clinically. It is usually diagnosed by imaging and histological methods.

Patient-related post-ERCP pancreatitis (PEP) risk factors between two groups of patients: Prophylactic pancreatic stent and rectal indomethacin.

Background: Pancreatitis is one of the most crucial complications following endoscopic retrograde cholangiopancreatography (ERCP). The purpose of the current study was to investigate patient-related post-ERCP pancreatitis (PEP) risk factors in two groups of patients: prophylactic pancreatic stent and rectal indomethacin. Methods: Two different prophylactic modalities were planned and complications were assessed based on the defined inclusion criteria. In this study, the patients were evaluated for the procedure and patient-related risk factors in post-ERCP pancreatitis in the recipient groups of the prophylactic pancreatic stent and rectal indomethacin. Results: Pancreatitis was confirmed in 27 of all 170 selected patients after ERCP. By univariate analysis, two variables were significant with the development of PEP. Regarding the patient-related risk factors, unique subjects with common bile duct (CBD) dilated 10mm were more exposed to an increased chance of PEP (P=0. 015); meanwhile, other factors did not correlate with the increased possibility of PEP in both groups. The only procedure-related risk factor for PEP was the deep cannulation of the pancreatic duct in both groups during the procedure with an incremental significant incidence of pancreatitis (P=0.005). Comparison of prophylactic pancreatic stent and rectal indomethacin showed no effects in term of post ERCP pancreatitis reduction. Additionally, there was no significant difference between these two strategies in the rate of PEP. Conclusion: Prophylactic pancreatic duct stents and administration of rectal indomethacin cannot have particular approaches for reducing the possible occurrence of PEP. The increase in time of deep cannulation and the presence of CBD dilation <10mm could be considered as important risk factors.

Pancreatic Squamous Cell Carcinoma.

Pancreatic squamous cell carcinoma (SCC) is a rare event. Here, we present a 56-year-old man with pancreatic SCC. Imaging methods demonstrated a hypodense mass at the head and trunk of the pancreas. Also, some lymphadenopathy has been seen around the pancreas and para-aorta. The mass created pressure and encasement on the celiac trunk, portal vein, and arteries of the liver and spleen. Endoscopic ultrasound showed a mass lesion of 45-37 mm (mixed echoic) at the trunk of the pancreas. Histological examination of the endoscopic ultrasound-guided fine needle aspiration specimen confirmed the diagnosis of SCC. The disease is highly aggressive, most often locally advanced or metastatic at diagnosis, and poorly responsive to treatment. It also has generally poor survival rates.

Secondary Sclerosing Cholangitis and Hodgkin's Lymphoma.

CONTEXT: Liver damage is relatively common in patients affected by HL, but paraneoplastic cholestasis is an uncommon presenting symptom in HL. CASE REPORT: We report the case of a 38-year-old man who came to our hospital with jaundice, pruritis, nausea, vomiting, weight loss, and recurrent episodes of fever without any hepatosplenomegaly or lymphadenopathy. Laboratory findings showed abnormal liver functioning with mixed hepatocellular and cholestatic patterns. Sonographic evaluation of the biliary tract was normal. We ruled out viral infections, autoimmune process, and hemochromatosis. The patient was put on ursobile and NAC (N-acetyl-systeine) and prednisolone treatment. In magnetic resonance cholangiopancreatography examination, there were multiple strictures in the intrahepatic and extrahepatic bile ducts with mild dilatation. Histologic finding of liver biopsy was compatible with sclerosing cholangitis or drug-induced cholestasis. General condition and laboratory examination results of the patient became better, but we found lymph-adenopathy on monthly follow-up examination. Histological finding of the lymph node was compatible with HL. CONCLUSION: This report emphasizes that HL can be presented with different paraneoplastic symptoms and that one of them is secondary sclerosing cholangitis. It has better prognosis than vanishing bile duct syndrome, and perhaps steroid treatment can be suggested.

A successful management of aluminum phosphide intoxication.

BACKGROUND: Aluminum Phosphide or rice tablet is one of the most common pesticides which leads to accidental or intentional acute intoxication and finally death. In this paper, we describe a successful management of intoxication with rice tablet in a young girl. CASE PRESENTATION: A 14-year-old girl was admitted due to consumption of rice tablet. Gastric washing with two vials of sodium bicarbonate and discharge suction was done. In the first 24 hours, the patient underwent recurrent hydration, dopamine infusion with sodium bicarbonate, calcium, magnesium and amiodarone. On the second day of admission, the patient was transferred to intensive care unit (ICU) and five days later, she was discharged without liver or renal complications. CONCLUSION: Short interval between consumption of this tablet and start of the treatment and on time rescue to the patient can be some of the important factors to prevent early death in intoxication with this tablet.
