Fibronectin glomerulopathy (FG) is caused by fibronectin 1 (FN1) gene mutations. A renal biopsy was performed on a 4-year-old girl with incidentally discovered proteinuria (150 mg/dL); her family history of disease negative. Markedly enlarged glomeruli (mean glomerular diameter: 196 μm; age-matched controls: 140 μm), α-SMA-positive and Ki-67-positive mesangial cell proliferation (glomerular index 1.76), the mild expansion areas, no immune or electron-dense deposits, normal basement membrane,...
The advent of digital nephropathology offers the potential to integrate deep learning algorithms into diagnostic workflow. We introduce PICASO, a novel permutation-invariant set operator dynamically aggregate histopathologic features from instances. applied PICASO two scenarios: detecting active crescent lesions in sets glomerular crops with IgA nephropathy and case-level classification for antibody-mediated rejection (AMR) kidney transplant. is Transformer-based that aggregates instances...
A primer aldosteronismus a leggyakoribb endokrin hypertoniaforma, az összes eset körülbelül 5-20%-a. Egy fiatal, obes nőbeteget először 2014-ben vizsgáltunk ki rezisztens hypertonia miatt, de akkor szekunder okot nem találtunk elhízáson kívül. 2023-ban vérnyomása megemelkedett, hypokalaemia jelent meg.

Short stature, emaciation, latte-colored skin, freckles, hawk-like nose four patients, limited intellect two restrictive lung one...
ABSTRACT Background The decision to accept or discard the increasingly rare and marginal brain-dead donor kidneys in Eurotransplant (ET) countries has be made without solid evidence. Thus, we developed validated flexible clinicopathological scores called 2-Step Scores for prognosis of delayed graft function (DGF) 1-year death-censored transplant loss (1y-tl) reflecting current practice six ET including Croatia Belgium. Methods training set was n = 620 DGF 711 1y-tl, with validation sets 158...
Considering the specific clinical management of neuroendocrine (NE) neoplasms (NENs), immunohistochemistry (IHC) is required to confirm their diagnosis. Nowadays, synaptophysin (SYP), chromogranin A (CHGA), and CD56 are most frequently used NE immunohistochemical markers; however, sensitivity specificity less than optimal. Syntaxin 1 (STX1) a member membrane-integrated protein family involved in neuromediator release, its expression has been reported be restricted neuronal tissues. In this...
Introduction: A subset of breast neoplasia is characterized by features neuroendocrine differentiation. Positivity for Neuroendocrine markers immunohistochemistry required the diagnosis. Sensitivity and specificity currently used are limited; based on definitions WHO Classification Tumours, 5th edition, about 50% tumors with differentiation express chromogranin-A 16% synaptophysin. We assessed applicability two novel markers, syntaxin-1 insulinoma-associated protein 1 (INSM1) in carcinomas....
Abstract Background The diagnostic performance of PLA2R and IgG subclass staining kidney biopsies relative to anti-PLA2R seropositivity in the differentiation primary secondary membranous nephropathy (pMN, sMN) was examined. Besides – which has a lower specificity than antibody serology there is insufficient knowledge decide IgG1-4 subtype immunohistological patterns (IgG4-dominance, IgG4-dominance/IgG1-IgG4-codominance or IgG4-dominance/IgG4-codominance with any subtype) could be used...
Syntaxin‐1 (STX1) is a recently described highly sensitive and specific neuroendocrine marker. We evaluated the applicability of STX1 as an immunohistochemical marker in pulmonary neoplasms (NENs). compared with established markers, including insulinoma‐associated protein 1 (INSM1). Typical carcinoids (n = 33), atypical 7), small cell lung carcinomas ([SCLCs] n 30), large 17) were immunostained using tissue microarray for STX1, chromogranin A, synaptophysin, CD56, INSM1. Eighty‐four...
This study highlights the importance of a combined diagnostic approach in diagnosis rare diseases, such as adult-onset genetic FSGS. We present three adult patient cases evaluated with kidney biopsy for proteinuria, chronic disease, and hypertension, which were suggestive Renal samples formalin-fixed, paraffin-embedded fetal kidneys using standard light microscopical stainings, direct immunofluorescence on cryostat sections, electron microscopy. Clinical exome sequencing was performed each...
Veno-venous extracorporeal membrane oxygenation (vv-ECMO) can save lives in severe respiratory distress, but this innovative approach has serious side-effects and is accompanied by higher rates of iatrogenic morbidity. Our aims were, first, to establish a large animal model vv-ECMO study the pathomechanism complications within clinically relevant time frame and, second, investigate renal reactions increase likelihood identifying novel targets improve clinical outcomes vv-ECMO-induced acute...
Oligomeganephronic hypoplasia, commonly referred to as oligomeganephronia (OMN), is a rare pediatric disorder characterized by small kidneys. Histologically paucity of nephrons observed which show compensatory enlargement. Hyperfiltration injury leads end-stage kidney disease. Here we report 23-year-old Caucasian female patient who presented with 7-year history nonnephrotic proteinuria, slow worsening renal function, normal-sized kidneys, normal blood pressure, healthy weight, and...
Death with a functioning graft and death-censored renal allograft failure remain major problems for which effective preventative protocols are lacking. The retrospective cohort study aimed to determine whether histologic changes on 5-year surveillance kidney biopsy predict adverse outcomes after transplantation in recipients who had: both Type 2 diabetes (T2DM) obesity (BMI ≥ 30 kg/m2 ) at the time of (T2DM/Obesity, n = 75); neither (No T2DM/No obesity, 78); No T2DM/Obesity (n 41), 47). On...
