Endocrine differentiation of extra-pulmonary small cell carcinoma demonstrated by immunohistochemistry using antibodies to PGP 9.5, neuron-specific enolase and the C-flanking peptide of human pro-bombesin

Several recent studies have confirmed the endocrine nature of small cell carcinoma of the lung. In extra-pulmonary sites, small cell 'undifferentiated' carcinomas have classical morphological features similar to their pulmonary counterpart. We therefore investigated, using immunocytochemistry, the possibility that the non-pulmonary neoplasms may also be endocrine in nature. Sections of 29 small cell carcinomas from oesophagus, stomach, larynx, colon and urinary bladder were immunostained using antisera to protein gene product 9.5 (PGP 9.5), neuron-specific enolase (NSE), cytokeratin, leucocyte common antigen and peptides including bombesin, the C-flanking peptide of human probombesin, adrenocorticotrophic hormone, neurotensin, calcitonin and pancreatic polypeptide. All the tumours showed immunoreactivity for at least one of the two general endocrine markers PGP 9.5 and NSE. Twenty-three of the 29 cases were immunoreactive for PGP 9.5, 27 for NSE. All were positive for cytokeratin and negative for leucocyte common antigen. Of the regulatory peptides, immunoreactivity was obtained with antisera to bombesin (one case), the C-flanking peptide of human pro-bombesin (14 cases), adrenocorticotrophic hormone (one case) and calcitonin (three cases). No PGP 9.5-, NSE- or peptide-like immunoreactivity was detected in 25 control tumours from similar sites, including lymphomas and poorly differentiated tumours. These results suggest that non-pulmonary small cell carcinoma has an endocrine character.     

Blood biomarkers of mild traumatic brain injury: State of art

BackgroundMild traumatic brain injury (mTBI) is one of the most common causes of emergency department visits around the world. Up to 90% of injuries are classified as mTBI. Cranial computed tomography (CCT) is a standard diagnosis tool to identify intracranial complications in adults with mTBI. Alternatively, children can be admitted for inpatient observation with CCT scans performed only on those with clinical deterioration. The use of blood biomarkers is a supplementary tool for identifying patients at risk of intracerebral lesions who may need imaging.MethodWe realised a bibliographic state of art providing a contemporary clinical and laboratory framework for blood biomarker testing in mTBI management.ResultsThe S100B protein is the only biomarker that can be used today in the clinical routine for management of mTBI with appropriate evidence-based medicine. Due to its excellent negative predictive value, S100B protein is an alternative choice to CCT scanning for mTBI management with considered, consensual and pragmatic use. In this state of art, we propose points to help clinicians and clinical pathologists use serum S100B protein in the clinical routine. A state of art on the different biomarkers (GFAP, UCH-L1, NF [H or L], tau, H-FABP, SNTF, NSE, miRNAs, MBP) is also conducted. Some of these other biomarkers, used alone (GFAP, UCH-L1) or in combination (GFAP + H-FABP ± S100B ± IL10) can improve the specificity of S100B.ConclusionUsing a bibliographic state of art, we highlighted the added values of the blood biomarkers for the clinical management of mTBI.

神经元特异性烯醇化酶和脑钠肽在中老年基底节区出血 85例预后中的应用研究

目的探讨神经元特异性烯醇化酶( NSE)和脑钠肽在中老年基底节区出血病人预后评估中的应用价值。方法选择 2020年 1月至 2022年 12月在安徽医科大学附属滁州医院治疗的 85例中老年基底节区出血病人进行回顾性分析,根据病人发病后 3个月的改良 Rankin量表( mRS)评分,将病人分为预后良好组和预后不良组,利用受试者操作特征曲线( ROC曲线)和 logistic回归分析评估 NSE和脑钠肽的预后价值。结果预后良好组中 NSE(13.67±4.51)μg/L明显低于预后不良组(18.36±6.52)μg/L(P<0.001)预后良好组中脑钠肽 143.00(98.00,233.80)ng/L明显低于预后不良组 230.00(120.00,400.00)ng/L(P=0.002)。 ROC曲线显示,NSE和脑钠肽的最佳截取值分别为 15.5 μg/L和 156.5 ng/L。NSE联合脑钠肽时 AUC为 0.76,与二者单独应用时的 0.73、0.70差异无统计学意义。 logistic回归分析显示出血量( P=0.017)、 NSE(P=0.003)和脑钠肽( P=0.033)是影响病人预后的独立危险因素。结论 NSE和脑钠肽在中老年基底节区出血病人的短期预后评估中具有重要价值,值得进一步研究。
