Long-Segment Early Squamous Cell Carcinoma of the Proximal Esophagus: Curative Treatment and Long-Term Follow-Up after 5-Aminolevulinic Acid (5-ALA)-…
2006
Photodynamic therapy (PDT) is an established treatment for the ablation of dysplastic Barrett's epithelium and early esophageal carcinoma, but no data have been published on curative 5-aminolevulinic acid (5-ALA)-PDT for long-segment early esophageal cancer with infiltration of the upper sphincter. We describe successful curative treatment of an unusual early long-segment squamous cell carcinoma (uT1a,N0) of the proximal esophagus (18 - 28 cm aborally), with three sessions of 5-ALA-PDT. Endoscopic and endosonographic follow-up macroscopically showed a complete remission of the tumor, proven by biopsy showing total histological ablation. After a follow-up period of 23 months, there has been …
Diagnostic efficacy of the fluorometric determination of enzyme activity for Pompe disease from dried blood specimens compared with lymphocytes-possi…
2009
Pompe disease is a rare, autosomal-recessive disorder which results from a defect in the lysosomal enzyme acid alpha-glucosidase (GAA). The onset of this disease is highly variable, with infantile types being the most severe. Traditionally, lymphocytes, fibroblasts or muscle biopsies were necessary for enzyme activity measurement, because these materials do not express maltase-glucoamylase (MGA) that interferes with the assay. Recently, acarbose was found to inhibit MGA activity selectively, so that dried blood became accessible for GAA assessment.To evaluate the diagnostic efficacy of GAA measurement in dried blood specimens (DBSs) in comparison with lymphocytes. If DBSs provided reliable …
Potential Diagnostic Properties of Chest Ultrasound in Thoracic Tuberculosis-A Systematic Review.
2018
Background: Chest ultrasound (CUS) has been shown to be a sensitive and specific imaging modality for pneumothorax, pneumonia, and pleural effusions. However, the role of chest ultrasound in the diagnosis of thoracic tuberculosis (TB) is uncertain. We performed a systematic search in the medical literature to better define the potential role and value of chest ultrasound in diagnosing thoracic tuberculosis. Aim: To describe existing literature with regard to the diagnostic value of chest ultrasound in thoracic tuberculosis. Methods: MEDLINE, EMBASE, and Scopus databases were searched for relevant articles. We included studies that used chest ultrasound for the diagnosis or management of any…
Handling and pathology reporting of specimens with carcinoma of the urinary bladder, ureter, and renal pelvis.
2003
Abstract Objective: Pathologists play a pivotal role in the diagnosis and in the report of the pathological features related to prognosis. Methods: To meet these endpoints, the following issues must be accomplished: adequate information about the patient history, proper handling of the specimens, identification of the reliable histopathological techniques necessary to reach the more detailed diagnostic information and evaluate the prognostic variables, and a standardized pathological report. Results: Recent efforts to standardize the histopathological evaluation have generated significant confusion among the urological and pathological communities as well. No consensus has been achieved abo…

Hautknoten und Ulzera der Extremitäten bei einem Patienten mit rheumatoider Arthritis
2002
CASE HISTORY: While being treated with corticosteroids and methotrexate for rheumatoid arthritis, a 63-year-old man developed livid nodules on his lower arms, hands and feet, as well as fever, necrotizing skin ulcers and rupture of a finger extensor tendon. INVESTIGATIONS: No vasculitis was found in a biopsy of one of the nodules on the lower arm. Fast growing mycobacteria, classified as M. marinum by PCR, were cultured from wound swabs. TREATMENT AND COURSE: The lesions healed on administration of ciprofloxacin, ethambutol and clarithromycin as well as local treatment. CONCLUSION: Cutaneous lesions of an atypical mycobacterial infection are often misdiagnosed. This is especially so in immu…
Sentinel-node biopsy in early stage ovarian cancer: a prospective multicentre study (SELLY)
2019
BackgroundSystematic para-aortic and bilateral pelvic lymphadenectomy is included in the standard comprehensive surgical staging in presumed early epithelial ovarian cancer. No prospective randomized evidence suggests it has potential therapeutic value, and related morbidity is not negligible.Primary Objective(s)To assess sensitivity, safety, and feasibility of the sentinel lymph node technique in identifying the presence of lymph node metastases in patients with early stage epithelial ovarian cancer.Study HypothesisSentinel lymph node detection with indocyanine green can accurately predict nodal status in a cohort of women with early stage epithelial ovarian cancer.Trial DesignThe SELLY tr…
Biochemical biomarkers of NAFLD/NASH
2020
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the Western world and the global epidemics of obesity and type 2 diabetes have led to a dramatic increase of its prevalence and incidence. Among NAFLD patients, those with nonalcoholic steatohepatitis (NASH) have a double risk of fibrosis progression, that is the main driver toward the evolution in cirrhosis and its complications, including hepatocellular carcinoma and hepatic decompensation. Furthermore, patients with NAFLD are also at risk for cardiovascular diseases and extrahepatic malignancies, that represent the first and the second cause of death, respectively. The availability of non-invasi…
Use of multiparametric magnetic resonance imaging and fusion-guided biopsies to properly select and follow African-American men on active surveillance
2019
OBJECTIVES To determine the rate of Gleason Grade Group (GGG) upgrading in African-American (AA) men with a prior diagnosis of low-grade prostate cancer (GGG 1 or GGG 2) on 12-core systematic biopsy (SB) after multiparametric magnetic resonance imaging (mpMRI) and fusion biopsy (FB); and whether AA men who continued active surveillance (AS) after mpMRI and FB fared differently than a predominantly Caucasian (non-AA) population. PATIENTS AND METHODS A database of men who had undergone mpMRI and FB was queried to determine rates of upgrading by FB amongst men deemed to be AS candidates based on SB prior to referral. After FB, Kaplan-Meier curves were generated for AA men and non-AA men who th…
THU0248 GLOMERULAR AND TUBULOINTERSTITIAL LESIONS IN PER-PROTOCOL REPEAT BUT NOT BASELINE KIDNEY BIOPSY PORTEND RELAPSE AND LONG-TERM RENAL FUNCTION …
2020
Background:In patients with lupus nephritis (LN), clinical response to treatment and renal histopathology have been shown to be discordant. No clinical or laboratory markers have to date been shown to reliably portend renal prognosis, in particular renal function impairment.Objectives:To investigate whether per-protocol repeat renal biopsies are predictive of LN relapses and long-term impairment of renal function.Methods:Forty-two patients with an incident biopsy-proven active proliferative (class III/IV ± V) LN from the LN database of the Université catholique de Louvain were included in the present retrospective study. Per-protocol repeat kidney biopsies were performed in all patients aft…
