Immunotherapy has improved survival outcomes of patients with advanced melanoma. Lower gastrointestinal tract immune-related adverse events (irAEs) are common during treatment; however, gastritis is not frequently observed. Herein, we report a case of severe cytomegalovirus (CMV)-related gastritis in a patient treated with ipilimumab and nivolumab for metastatic melanoma.

Background: Current guidelines strongly recommend the use of validated classifications to support optical diagnosis of lesions with advanced endoscopic imaging in the lower gastrointestinal tract. However, the optimal strategy in inflammatory bowel disease (IBD) is still a matter of debate.

Objectives: To analyze the accuracy of endoscopic classifications or single predictors for lesion characterization during endoscopic surveillance of IBD with advanced endoscopic imaging.

Article Synopsis
  • A study compared the effectiveness of four biologic drugs—adalimumab, infliximab biosimilar, golimumab, and vedolizumab—used to treat ulcerative colitis (UC) in Italy, focusing on achieving continuous clinical remission (CCR).
  • Researchers analyzed data from 416 UC patients treated from 2014 to 2019, measuring success based on a strict CCR definition over one year.
  • Results showed similar CCR rates among the four drugs, with vedolizumab proving more effective for patients who had previously failed anti-TNFα treatments, while safety profiles were comparable across all drugs.

Introduction: Methotrexate (MTX) is included in the therapeutic armamentarium of Crohn's disease (CD), although its positioning is currently uncertain in an era in which many effective biological drugs are available. No systematic reviews or meta-analysis have stratified the clinical outcomes of MTX according to the specific clinical scenarios of its use.

Methods: Medline, PubMed and Scopus were used to extract eligible studies, from database inception to May 2021.

Background And Aim: Since the outbreak of COVID-19, concerns have been raised as to whether inflammatory bowel disease (IBD) patients under biologic therapy may be more susceptible to the disease. This study aimed to determine the incidence and outcomes of COVID-19 in a large cohort of IBD patients on biologic therapy.

Methods: This observational retrospective multicenter study collected data about COVID-19 in IBD patients on biologic therapy in Italy, between February and May 2020.

Article Synopsis
  • The text discusses the need for efficient and low-cost fabrication methods for nanoscale devices, particularly focusing on the challenges of creating metal/organic semiconductor interfaces.
  • It introduces a room temperature, electroless process that deposits a controlled nanostructured silver layer on organic semiconductors using AgF solutions, achieving uniform coverage in just 20 minutes.
  • The study highlights that this metallic deposition alters the electrical properties of the semiconductor by inducing p-doping through a redox reaction.

Objectives: Hepatitis C virus (HCV) core antigen is a recently developed marker of hepatitis C infection. We compared the predictive power of HCV core antigen with reverse transcription polymerase chain reaction (RT-PCR) and branched DNA assay for HCV-RNA as markers of infection and response to interferon therapy.

Methods: Four hundred and forty-four sera from 111 patients (65 men, 52 yr) with chronic hepatitis C, receiving ribavirin together with standard interferon (n = 61) or pegylated interferon (n = 50) were retrospectively investigated.

Purpose Of The Work: Can patients derive a real benefit from increasing the number of prostate biopsies as regards Hodge's method (3 biopsies PZ per lobe) or can they only suffer from an eventual increase in complications?

Materials And Methods: From January 1998 to May 2001 we did 324 biopsies sextant with 6 biopsies (3 biopsies PZ per lobe), 146 of which (45%) were positive for tumour. We did the prostate mapping (6 PZ: 1 TZ: 1 AZ per lobe) on 97 patients who kept on having PSA alterations even though they were negative. Of these 97, 10 (10.

Purpose Of The Work: Is it convenient to do the prostate biopsy for the patients with PSA between 3 and 3.9 ng/ml?

Materials And Methods: From January 1998 to April 2001 we did 421 transrectal prostate biopsies echoconducted, 84 of which (20%) done on patients with a PSA between 3 and 3.9 ng/ml.

We compared two commercial assays for quantification of serum hepatitis C virus (HCV) RNA to investigate whether pretreatment levels of serum HCV RNA could predict the outcome of interferon (IFN) therapy. The Amplicor HCV Monitor test is based on a single, combined reverse transcription and amplification reaction carried out by the Tth DNA polymerase using specific primers for the 5' untranslated (UTR) region. The Quantiplex HCV RNA 2.

We describe a patient with pulmonary tuberculosis and a rare disturbance of leukocyte segmentation, known as "Pelger-Huët anomaly", which can be observed in various diseases such as malignancies and/or infections. The importance of this association is equivocal: some authors have related to the association the particular severity of tuberculosis or the death they observed; in the case reported we noted no evidence of such a relation, notwithstanding the presence of the homozygous form of the Pelger-Huët anomaly. We suggest therefore that, when Pelger-Huët anomaly is found, an underlying disease should be searched for; the course of this illness, however, might not be affected.

Actually scrotal ambulatory surgery represents a necessity for the surgeon because of the more and more greatest request to admittance and because of the impossibility to admit patients with less severe diseases. Ambulatory treatments allows psychological advantage, less discomfort, less hospital complications for the patients and a reduction of sanitary expense. Light general anaesthesia with concomitant administration of local anaesthesia is performed in our Institute.

We subjected to a functional and metabolic evaluation (urodynamic examination + cystography) 10 patients underwent to radical cystectomy with a ileal orthotopic reservoir (VIP) for bladder cancer. At the moment patients have a minimum 3-years follow-up and they are out of disease. The medium capacity of the reservoir is about 447 ml, with a low pressure flow, a medium pressure of ureteral closing of 62.

To compare the long-term effectiveness and tolerability of lymphoblastoid interferon (IFN-alphaN1) and recombinant interferon alfa 2a (IFN-alpha2a) in patients with chronic hepatitis caused by hepatitis C virus (HCV), 234 consecutive patients with HCV-related chronic hepatitis were randomized prospectively to receive titrated doses (starting dose = 6 million units [MU]) of IFN-alpha2a (n = 118) or IFN-alphaN1 (n = 116) for 12 months. HCV RNA was detected by reverse-transcription polymerase chain reaction (RT-PCR), quantified by branched-DNA (bDNA) assay, and genotyped by reverse hybridization assay. Thirty-one patients in the IFN-alpha2a group and 28 in the IFN-alphaN1 group (total, 59 [25%] had normal transaminases and undetectable HCV RNA by RT-PCR after 12 months of therapy, but only 19 in the first group and 20 in the second group (total, 39 [17%]) had biochemical and virological responses 12 months after treatment was discontinued.

The role of familial environment in the spreading of hepatitis C virus (HCV) infection is not well established. We studied 1670 family members for 578 anti-HCV+ subjects enrolled in 8 centres distributed throughout Italy. The prevalence of anti-HCV positivity was significantly higher in spouses than in offspring (15.

The efficacy and tolerability of 12-month treatment with titrated doses of recombinant interferon-alpha 2a (IFN-alpha 2a) in chronic hepatitis C were studied in 67 consecutively recruited patients randomly assigned either to a starting dose of IFN-alpha 2a 6 MU, subsequently adjusted to the serum alanine aminotransferase (ALT) response (n = 35), or to no therapy (n = 32; controls). End-of-treatment ALT levels were normal and hepatitis C virus (HCV) RNA was negative by nested polymerase chain reaction (PCR) in 17 (49%) treated patients compared to none of the controls (P < 0.001).
