ABSTRACT Objectives Odontogenic sinusitis (ODS) refers to purulent sinusitis caused by infectious maxillary dental pathologies, with > 90% occurring unilaterally. While various clinical features suggest ODS, diagnosing some ODS patients can be challenging. This study aimed to determine the value of maxillary sinus papillary edema (MSPE) in predicting ODS. Methods A retrospective cohort study was conducted on patients who underwent at least maxillary antrostomy for unilateral sinus disease (USD). Adequately powered samples of three USD cohorts were generated: ODS, infectious maxillary CRS without nasal polyps (CRSsNP), and noninfectious CRSwNP. Multiple variables were collected, but the primary outcome was MSPE presence via double‐blinded endoscopic image review by three rhinologists. Inter‐rater agreement was calculated, and a predictive model for MSPE was generated. Results Of 41 ODS, 22 infectious CRSsNP, and 13 noninfectious CRSwNP patients, mean age was 57.0 years and 55.3% were female. There was almost perfect agreement between rhinologists when assessing for MSPE on endoscopic images ( κ = 0.927). MSPE was seen in 100% of ODS, 22.7% infectious CRSsNP, and 0% CRSwNP. MSPE was significantly more likely in ODS compared to non‐odontogenic CRS ( p < 0.0001), demonstrating 100% sensitivity and 89.1% specificity for ODS, with 85.7% positive and 100% negative predictive values. Conclusions MSPE is a distinct finding that is reliably identifiable and is significantly more likely in ODS compared to infectious CRSsNP and noninfectious CRSwNP. With 100% sensitivity and NPV, MSPE absence makes ODS very unlikely. With 86% PPV, MSPE is not pathognomonic for ODS, but should arouse suspicion for a possible odontogenic source.

Abstract Inflammatory bowel diseases (IBD), comprising Crohn’s disease and ulcerative colitis, are chronic, inflammatory, immune mediated, relapsing-remitting conditions of the gastrointestinal tract with multidimensional and often negative effects on patients’ quality of life. The global burden of IBD is increasing and is forecast to affect 1% of the population in early industrialized nations over the next 10 years. Advances in our understanding of the causes and pathogenesis of IBD in the past three decades have translated into new treatments that modulate the immune inflammatory cascade. Modern goals of treatment are clinical remission through assessment of patient reported outcomes and deep remission defined as mucosal healing on colonoscopy or imaging. Achieving both clinical and deep remission affords patients a better long term prognosis and quality of life. This review summarizes the latest evidence on IBD diagnosis, staging, and prognosis, with a detailed focus on current treatments.

Objective: The objective of this investigation was to evaluate the agreement rate on judgments made using the Murad tool by different systematic review teams. Introduction: Evaluating the methodological quality of case reports and case series is challenging but some tools do exist for this purpose. We leveraged the presence of studies that have been evaluated by different systematic review teams to assess the inter-consensus agreement among different teams on Murad tool domains. Methods: Using a back-citation method, we identified systematic reviews that used the Murad tool and retrieved all the included primary studies. We selected studies that were assessed by more than 1 systematic review team. We calculated observed agreement and Gwet’s agreement coefficient on judgments made about each signaling question. Results: We identified 982 systematic reviews that cited the Murad tool and collectively cited 59,080 references. The final data comprised of 81 duplicated case reports and series assessed by more than 1 systematic review team. Overall, the signaling questions had very high observed agreement with 5 of the 8 questions having agreement over 75%. The signaling questions with the highest agreement addressed the adequacy of the ascertainment of the exposure (coefficient 0.959), ascertainment of the outcome (coefficient 0.829), presence of a dose-response gradient (perfect agreement), and clarity of reporting (coefficient 0.755). Conclusion: The current study demonstrates overall high agreement among different systematic review teams that used the Murad tool for appraisal of the same case series and case reports. Leveraging duplicated studies across systematic reviews is a feasible way to retrospectively assess the reliability of the tool.

ABSTRACT Background and Aims Chronic inflammatory demyelinating polyradiculoneuropathy ( CIDP ) is a common, treatable, autoimmune, neuropathy frequently misdiagnosed. The complex electrodiagnostic ( EDX ) criteria required for diagnosis are challenging to apply in routine practice. This study evaluates the effectiveness of a machine‐assisted EDX tool in real‐time identification of demyelinating nerve conduction studies ( NCS ) stipulated by 2021‐ EAN / PNS CIDP criteria in conjunction with an online CIDP clinical probability calculator. Methods We prospectively evaluated 100 consecutive patients with referral or EDX diagnosis of polyradiculoneuropathy beginning January 1, 2024. Fifty patients were included, each from Jacksonville and Rochester Mayo Clinics. Routine electromyography ( EMG ) reports were compared to a machine‐assisted support tool applying 2021‐ EAN / PNS CIDP EDX criteria to NCS assessing demyelination. The EDX ‐assistant performance was compared to the final clinical diagnosis and our previously reported online CIDP clinical prediction tool ( https://news.mayocliniclabs.com/cidp‐calculator/ ). Results Among 100 patients (60% male; median age 64), 30 had a final clinical CIDP diagnosis with 29 having intravenous immunoglobulin follow‐up; 27 (93%) improved and 2 (7%) stabilized. Routine EMGs reported demyelination in 14 of 30 (47%), with 46% sensitivity and 79% specificity. The EDX ‐assistant identified CIDP demyelination in 28 of 30 (93%), with 93% sensitivity and 57% specificity. The clinical calculator detected CIDP in 30 of 30 (100%) with 86% specificity, increasing to 94% after excluding false positives lacking demyelinating features on the EDX tool. Interpretation A real‐time machine‐assisted EDX support tool, used with a clinical web‐based calculator, streamlines CIDP assessment by improving standardized identification of 2021‐EAN/PNS CIDP demyelinating NCS criteria and aiding clinical decisions.

Introduction The safety of operating room extubation (ORE) immediately following cardiac surgery via median sternotomy remains unclear. However, reported outcomes in the setting of parasternal regional analgesia are limited. This study examined the safety of ORE for patients who received postoperative superficial parasternal intercostal plane (SPIP) blocks following median sternotomy for cardiac surgery. Methods Single-center retrospective cohort study from January 2020 to September 2023 compared the outcomes of adult cardiac surgical patients who were either extubated in the operating room immediately after surgery with SPIP blocks (ORE-B), received SPIP blocks and were extubated in the intensive care unit within 6 hours (FTE-B) or did not receive SPIP blocks and were extubated in the intensive care unit within 6 hours (FTE). Assessed outcomes were reintubation, use of non-invasive positive pressure ventilation (NIPPV), intensive care unit (ICU) readmission, return to OR, postoperative transfusion, ICU and hospital length of stay. Results 2294 patients were studied, which included 256 ORE-B patients, 729 FTE-B patients and 1,309 FTE patients. Differences in reintubation rates (1.2% vs 0.7% vs 1.2%, all p≥0.26) and use of NIPPV (4.8% vs 4.8% vs 5.1%, all p≥0.743) did not differ between ORE-B, FTE-B, and FTE groups, respectively. Time to extubation differed between FTE-B and FTE groups (2.5 hours vs 3.8 hours, p=<0.001), respectively. Additionally, hospital length of stay was significantly shorter for groups ORE-B and FTE-B compared with group FTE (5 days vs 5 days vs 6 days), respectively. Conclusions Selective ORE after median sternotomy for cardiac surgery was not associated with an increased risk of reintubation and NIPPV use in the setting of parasternal regional analgesia.

Introduction Despite the identification of multiple susceptibility loci by genome-wide association studies (GWAS), considerable chronic obstructive pulmonary disease (COPD) heritability remains unexplained. Aim To identify interaction networks of airway epithelial cell DNA methylation in COPD and further explore potential correlations with airway bacterial composition, as potentially collective regulators of biological pathways influencing COPD severity. Methods Using DNA isolated from bronchial airway brushings of 67 ever-smokers (>20 pack-years) from the SubPopulations and InteRmediate Outcomes Measures in COPD Study (SPIROMICS), we assessed proportion of DNA methylation (β) by epigenome-wide association study (EWAS) and examined associations of differentially methylated CpG probes (DMPs) with risk for moderate-to-severe COPD (N=34) versus absent or mild COPD (N=33). We tested co-methylation modules generated by Weighted Correlation Network Analyses (WGCNA) for associations with moderate-to-severe COPD and with bacterial genus-level relative abundances (16S rRNA sequencing). Results EWAS-identified nominally significant DMPs enriched for lung function GWAS loci. Eigengenes in six WGCNA modules were associated with moderate-to-severe COPD (false discovery rate <0.05). Four of those modules were enriched for forced expiratory volume in 1 s/forced vital capacity GWAS loci, and five overlapped with DMPs from EWAS. Overlapping CpG loci in three COPD-associated modules were adjacent to mucin genes; one had 10 genes highly ranked by connectivity with MUC5B, including important pathway genes: B3GNT6 , DGKI and ITGA8 . CpGs in an independent COPD-associated module showed the most correlations with Rothia , with directionality suggestive of negative associations with moderate-severe COPD. Conclusions Bronchial epithelial DNA methylation modules enriched for lung function GWAS loci associate with COPD severity in SPIROMICS. Potential module relationships to bronchial bacterial composition require further validation.

Myoma uteri is the most common benign tumour in women, but myomatous erythrocytosis syndrome (MES) is rare. MES is characterised by erythrocytosis, a myomatous uterus and blood normalization after hysterectomy or myomectomy. It increases the risk of thromboembolic events, making early recognition crucial. A premenopausal, nulliparous woman in her 50s with dyslipidaemia and obesity presented with a 20-week-sized abdominopelvic mass but no abnormal uterine bleeding. CT imaging revealed a large right adnexal mass. Lab tests showed isolated erythrocytosis with normal tumour markers and serum erythropoietin (Epo). Hysterectomy and bilateral salpingo-oophorectomy confirmed multiple uterine myomas, the largest measuring 19.5 cm, along with a right ovarian haemorrhagic cyst. Postoperatively, her blood levels normalised, confirming MES. The exact mechanism remains unclear but may involve Epo production. While Epo is often linked to myomas, some cases, like ours, show normal levels, highlighting the need for further research to understand MES and develop targeted treatments.
