Immunohistochemical staining revealed diffuse expression of H3G34R and P53, but no expression of Olig2, ATRX, IDH1/2 and BRAF V600E in tumor cells in all three cases.Conclusions: H3 G34 DHG occurs more significantly in younger patients, and nearly all lesions are located in the cerebral hemisphere. MRI showed mass effects, edema and mild enhancement. The histological type showed glioblastoma structure and PNET morphology. Immunohistochemistry showed that the expression of H3G34R was more significant in PNET morphology.","PeriodicalId":50452,"journal":{"name":"Fetal and Pediatric Pathology","volume":" ","pages":"1-9"},"PeriodicalIF":0.7,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Myocardial damage, mitochondrial function, and mitochondria permeability transition pore (MPTP) opening were determined. The results, presented as means ± SD, were analyzed using SPSS.Results: Intrauterine hypoxia induced cardiac damage, mitochondrial dysfunction, and MPTP opening in neonatal rats. H/R led to apoptosis and MPTP opening. cTnI and apoptosis-inducing factor (AIF) levels were positively correlated with the degree of MPTP opening. The larger degree of MPTP opening combined with the significant increases in the Ca2+, ROS, and decreases in mitochondrial membrane potential and ATP levels. The larger degree of MPTP opening combined with the stronger release of cytochrome c and AIF.Conclusions: Increased MPTP opening may play a crucial role in perinatal asphyxia-induced myocardial damage in neonatal rats.","PeriodicalId":50452,"journal":{"name":"Fetal and Pediatric Pathology","volume":" ","pages":"1-19"},"PeriodicalIF":0.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143484424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Women with ICP (n = 84) were classified into two groups: (1) Early-onset ICP (n = 36): pregnancy duration at diagnosis <34 weeks; (2) Late-onset ICP (n = 48): pregnancy duration at diagnosis ≥34 weeks. Maternal and neonatal outcomes were compared among the three groups.Results: The assisted reproductive technology (ART) pregnancy rate and serum bile acid (SBA) levels were significantly higher in the early-onset ICP group with adverse perinatal outcome (APO) than those without. Notably, the birth weight was significantly lower among neonates in the early-onset group of ICP than among neonates in the late-onset ICP and control groups (p < 0.001). Birth weight (OR = 0.998, 95% CI: 0.997-0.999, p = 0.041)was associated with early-onset ICP, according to the multivariate analysis. Receiver-operating characteristic (ROC) analysis revealed that a cutoff value of 36.8 weeks for gestational age at diagnosis and 9.6 mmol/L for SBA can distinguish between ICP patients with APO and those without.Discussion: Early-onset ICP is associated with low birth weight. ART pregnancies and women with higher SBA concentrations needed to be closely monitor for possible adverse perinatal outcomes in early-onset ICP.","PeriodicalId":50452,"journal":{"name":"Fetal and Pediatric Pathology","volume":" ","pages":"1-17"},"PeriodicalIF":0.7,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143392373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Frozen sections and conventional sections of umbilical cord prepared and examined for inflammation by two researchers. Diagnostic accuracy of frozen sections versus conventional sections evaluated for sensitivity and specificity in detecting funisitis.Results: The frozen section of the umbilical cord was 85.5% sensitive and 86.7% specific in diagnosing funisitis. The inter-rater agreement for diagnosing funisitis was 72.2%.

Results: Our search yielded three cases. A 20-month-old girl with a liver mass and serum alpha-fetoprotein (AFP) level of 46558.0 ng/mL. The neoplasm was papillary with Schiller-Duval bodies. A 2-year-old boy with hepatic masses and adrenal mass with a serum AFP of 106,604.5 ng/mL. Numerous Schiller-Duval bodies were present. A 7-month-old girl with a liver mass, lung nodules, and retroperitoneal masses. Serum AFP was in the 800s ng/mL. Hepatoid and microcystic YST were mixed with hepatoblastoma (HBL). All three cases were positive for CAM5.2, SALL4, Glypican-3, beta-catenin, and AFP.
