This study aimed to characterise the clinicopathological features of PEBL through a retrospective analysis of cases diagnosed at two institutions over a 15-year period. A total of 14 patients were identified, including seven women and seven men, with a median age of 63.5 years (range 21–76 years). These patients most often presented with symptoms of spinal cord compression, such as extremity paraesthesias, pain, and weakness. The thoracic region or thoracolumbar region was commonly involved in 10 (71%) patients. Eight (57%) patients had Lugano stage I disease, and 6six (43%) had stage II disease. Nine (64%) patients had a low or low-intermediate International Prognostic Index (IPI) score, and four (29%) patients had a high-intermediate or high score. All patients underwent surgical excision of the epidural mass, and histological analysis showed diffuse large B-cell lymphoma (DLBCL) in eight patients, follicular lymphoma in five patients, and high-grade B-cell lymphoma (HGBL) in one patient. Immunohistochemical analysis showed that all 14 cases were positive for pan B-cell markers and negative for CD3. Using the Hans algorithm, seven DLBCL cases had a germinal centre B-cell (GCB) immunophenotype and one case had a non-GCB immunophenotype. Fluorescence <em>in situ</em> hybridisation (FISH) analysis performed on eight cases showed one case of HGBL with <em>MYC</em> and <em>BCL6</em> rearrangements, four cases of DLBCL with isolated <em>BCL2</em> (<em>n=</em>2) or <em>BCL6</em> (<em>n=</em>2) rearrangements, and one case of DLBCL with <em>BCL2</em> and <em>BCL6</em> rearrangements. All 14 patients were treated with excision, 12 of whom were also treated with chemotherapy; three of these patients also received radiation therapy. One patient was treated with an autologous stem cell transplant and subsequently CAR-T therapy. Clinical follow-up was available for all patients with a median of 39.5 months (range 1–123 months). At the last follow-up, 13 patients were alive and in complete remission and one patient with HGBL died 9 months after diagnosis. We conclude that PEBL predominantly arises in older adults and most often affects the thoracolumbar region. Patients usually have a low or low-intermediate IPI score. The most frequent type of lymphoma is DLBCL with a GCB immunophenotype. In this cohort, most patients received chemotherapy and had a favourable prognosis.</div></div>","PeriodicalId":19915,"journal":{"name":"Pathology","volume":"58 1","pages":"Pages 24-29"},"PeriodicalIF":3.0,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145252153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These autoantibodies may confer distinct clinical features, including a lower likelihood of response to treatment with intravenous immunoglobulin (IVIg). There are currently limited options available for the detection of these autoantibodies in the diagnostic setting. We tested serum samples from 30 patients with CIDP, 40 disease controls [20 with myasthenia gravis and 20 with systemic lupus erythematosus (SLE)] and 52 healthy controls for the presence of antibodies against neurofascin 155 (NF155), neurofascin 186 (NF186), contactin-1 (CNTN1) and the contactin-1/contactin-associated protein 1 (CNTN1/CASPR1) complex using a commercial transfected HEK293 cell-based indirect immunofluorescence immunoassay (EUROImmun). We detected nodo-paranodal antibodies in six of 30 CIDP patients, including five who had previously tested positive for nodo-paranodal antibodies using enzyme-linked immunosorbent assay (ELISA). There was one positive test for anti-CNTN1 in a disease control with SLE and membranous glomerulonephritis, with no positive tests in healthy controls. We modified the manufacturer's staining protocol by using biotinylated anti-IgG and streptavidin-FITC labelling, which increased the analytical sensitivity of the assay. Our modified assay retained its robustness in the presence of interfering substances (haemolysed, lipaemic and icteric samples) and serum with high non-specific background immunofluorescent staining. We successfully modified and validated a commercial indirect immunofluorescence immunoassay for the qualitative detection of antibodies against NF155, NF186, CNTN1 and CNTN1/CASPR1. This could lead to more rapid diagnosis of patients with these autoantibodies, avoiding costly and ineffective treatments.</div></div>","PeriodicalId":19915,"journal":{"name":"Pathology","volume":"58 1","pages":"Pages 67-75"},"PeriodicalIF":3.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Determining the cause of death is crucial for both prevention and providing closure to families, yet many stillbirths are not adequately investigated. Autopsy and placental assessments are recognised as the gold standard for stillbirth investigation. The utility of these procedures can vary based on the quality of the examination. The aim of this study was to determine the quality of autopsy reporting in Australia in the context of stillbirth. A total of 284 stillbirths with accompanying autopsy reports from 18 maternity hospitals across Australia between 2013 and 2018 were included. Autopsy and placental pathology reports were scored against accepted standards using a modified Vujanic–Khong tool to produce an autopsy quality score (AQS), by a double-blinded panel of assessors to the cause of death. Outcome measures were the number of autopsy reports achieving the score range, with a minimal acceptable score (MAS) of 75%. Reports were assessed based on the type of investigation (full or external), presenting clinical scenario, maceration status, and gestational age. A secondary outcome was to review the format of the autopsy reports. In total, 248 (87%) autopsy reports achieved a MAS, with 166 (58%) of reports achieving 90% of an AQS; 37 (13%) cases did not achieve a MAS, including 14 external examinations, one partial autopsy examination and 23 full autopsy examinations. Full autopsy achieved a higher score than external examinations only. External autopsy examinations were more likely not to have requested medical imaging (59%), cytogenetics (72%), or microbiology (of the placenta, 72%) when thought to be clinically indicated. There was no difference in the MAS according to clinical scenario, gestational age or degree of maceration. There was no consistent autopsy report format in this study. The overall quality of autopsy reports across Australia is high, providing confidence in the use of these reports for classifying a cause of stillbirth. Development of a structured protocol for autopsy reporting to ensure all investigations deemed clinically appropriate are performed and formatting is harmonised across the country is recommended.</div></div>","PeriodicalId":19915,"journal":{"name":"Pathology","volume":"58 1","pages":"Pages 34-40"},"PeriodicalIF":3.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145275407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data are needed to inform new RSV vaccine use. We analysed laboratory data from all viral respiratory reverse transcription quantitative polymerase chain reaction (RT-qPCR) diagnostic tests conducted at New South Wales (NSW) Health Pathology in the South Eastern Sydney and Illawarra Health Service from 2018 to 2024. Panel and descriptive analyses were used to report annual RSV testing and detection by age group, care setting, and co-infection with other respiratory viruses using Stata v.18. Of 370,126 unique episodes tested for RSV, there were 13,293 (3.6%) detections. Public health measures for COVID-19 significantly impacted RSV circulation in 2020, with detections nearly absent in the winter season (June–August) and an off-season epidemic occurring in the summer. Annual testing and detection peaked in 2022 and was considerably higher than in pre-pandemic years (testing 6.3-fold and detection 3.4-fold higher than in 2019, respectively). Across the study period, incidence was highest in children aged &lt;5 years (1,613 per 100,000 population). Among older adults (≥60 years of age), prevalence was 125 per 100,000. Testing was primarily performed in outpatients (71%), of which emergency departments were the most frequent care setting (49%). Of all detections, 2,713 (20.4%) had co-infections, with the most commonly co-detected viruses being rhinovirus (37%) and bocavirus (17%). RSV testing increased from 2022 due to expanded respiratory screening, RSV becoming a notifiable disease, and COVID-19 epidemics. Multiplex RT-qPCR testing increased RSV detection, but testing bias exists, with children tested more than adults. Continued surveillance across age groups is essential to assess the impact of new immunisation strategies.</div></div>","PeriodicalId":19915,"journal":{"name":"Pathology","volume":"58 1","pages":"Pages 97-102"},"PeriodicalIF":3.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
