胺碘酮致甲状腺功能异常的诊治进展

胺碘酮是治疗心律失常的常用药物。但由于其富含碘及自身固有的特性,可导致一系列甲状腺功能的紊乱,甚至引发明显的甲状腺功能减退（甲减）或甲状腺功能亢进（甲亢）。对于胺碘酮所致甲减（AIH）的诊断和治疗目前比较清晰,但对胺碘酮所致甲亢（AIT）的诊断、鉴别其亚型及治疗有一定的难度。

Exploration research on the fusion of multimodal spectrum technology to improve performance of rapid diagnosis scheme for thyroid dysfunction

The spectral fusion by Raman spectroscopy and Fourier infrared spectroscopy combined with pattern recognition algorithms is utilized to diagnose thyroid dysfunction serum, and finds the spectral segment with the highest sensitivity to further advance diagnosis speed. Compared with the single infrared spectroscopy or Raman spectroscopy, the proposal can improve the detection accuracy, and can obtain more spectral features, indicating greater differences between thyroid dysfunction and normal serum samples. For discriminating different samples, principal component analysis (PCA) was first used for feature extraction to reduce the dimension of high‐dimension spectral data and spectral fusion. Then, support vector machine (SVM), back propagation neural network, extreme learning machine and learning vector quantization algorithms were employed to establish the discriminant diagnostic models. The accuracy of spectral fusion of the best analytical model PCA‐SVM, single Raman spectral accuracy and single infrared spectral accuracy is 83.48%, 78.26% and 80%, respectively. The accuracy of spectral fusion is higher than the accuracy of single spectrum in five classifiers. And the diagnostic accuracy of spectral fusion in the range of 2000 to 2500 cm^?1 is 81.74%, which greatly improves the sample measure speed and data analysis speed than analysis of full spectra. The results from our study demonstrate that the serum spectral fusion technique combined with multivariate statistical methods have great potential for the screening of thyroid dysfunction.     

胃癌和甲状腺疾病相关性研究进展

胃癌是我国常见的恶性肿瘤之一。多种因素与胃癌的发生相关,如环境、饮食、幽门螺杆菌感染、慢性萎缩性胃炎和肠上皮化生等。随着对胃癌研究的深入,国外学者发现胃癌的发病率在碘摄入不足或者摄入过多的地区有逐渐增高的趋势,而碘是甲状腺疾病发病的重要因素。最新的研究发现,胃癌和甲状腺疾病的关系可能受到地域因素的影响,但目前缺乏对此关系的大样本临床研究。本文试对这些研究的最新进展作一综述。     

甲胎蛋白在肝癌的诊断和治疗中的研究进展

肝细胞癌(Hepatocellular carcinoma,HCC)是致死率第3的恶性肿瘤,也是全球第5大常见癌症。肝癌在临床上的治疗手段非常有限,患者的总生存率也很低。因此,肝癌的早期诊断和治疗对于患者总生存率有着重要的影响。甲胎蛋白(Alpha-fetoprotein,AFP)是最早发现也是目前应用最广泛的肝癌标志物之一。目前,多项研究表明,作为一个特异性的癌基因,AFP在肝癌的发生、发展、诊断和治疗中有巨大的研究价值。文中简述了AFP在肝癌发生发展中的分子调控机制以及在肝癌细胞逃避免疫监视中的作用,着重阐述AFP作为重要的肝癌靶标分子在肝癌的临床诊断和治疗研究中的应用。     

The impact of the non‐invasive follicular thyroid neoplasm with papillary‐like nuclear feature terminology in the routine diagnosis of thyroid tumours

Background

Due to the recent proposal of the non‐invasive follicular thyroid neoplasm with papillary‐like nuclear feature (NIFTP) category, the authors analyse the state of the art in the challenging diagnosis of follicular thyroid neoplasms in routine practice.

Methods and results

A consecutive series of 200 histological diagnoses, with complete cytological correlation, was analysed following the introduction of the NIFTP definition. The study was conducted in a general hospital with a high prevalence of thyroid benign nodules that accounted for approximately 60% of surgically‐treated nodules. The significant incidence of the new NIFTP category was 7%. Concurrently, a gradual decrease of the follicular variant of papillary thyroid carcinoma (fvPTC) was observed (3.5%). When evaluating the FNA biopsies within the NIFTP group, despite the systematic evaluation of nuclear crowding, enlargement, irregularities and clearing, the final cytological class was often indeterminate for malignancy (Thy3/III‐IV, 71%). At histology, the application of the semiquantitative NIFTP score for the evaluation of the PTC‐like nuclear features was able to discriminate benign lesions (score 0/1) from fvPTC (score 2/3). A certain degree of overlapping still persisted between NIFTP and fvPTC (score 2) or between NIFTP and benign lesions (score 1).

Conclusions

In the routine evaluation of FNA biopsies, the presence of subtle and questionable PTC‐like nuclear features still remains a controversial aspect of the diagnostic workflow. Given that the NIFTP category was introduced to stratify the low‐risk group of thyroid tumours more precisely, pathologists should force themselves to apply the nuclear score rigorously and to classify cases assigned a score of 1 as benign proliferations.

     

Effects of covid-19 infection on thyroid functions

BackgroundCOVID-19 may affect many endocrine tissues as well as thyroid gland and hypothalamus-pituitary-thyroid axis. It has been shown that COV D-19 infection suppresses thyroid hormones in some studies and causes subacute thyroiditis in the others so that its effects are still not fully known. The aim of our study is to retrospectively evaluate thyroid functions, clinical findings, biochemical and inflammatory markers in PCR positive patients infected with COVID-19; and to evaluate the relationship between abnormal thyroid function tests (TFT) and clinical and laboratory findings and whether it has potential prognostic significance.MethodsThe data of patients aged 18 years and older, 201 patients who applied to Mersin City Training and Research Hospital due to COVID-19 infection between 1st of March and 1st of April in 2021 and received inpatient treatment were evaluated retrospectivelyResultsLarge TFT (TSH, T3, T4, anti-TPO) and laboratory data of 201 patients with mild, moderate or severe pneumonia on CT were scanned retrospectively. 121 (60.2%) of the patients were male, mean age was 51.9 ± 14.6 years, and the most common comorbid disease was hypertension in 65 (32.3%) patients.ConclusionsIt has been determined that the deterioration in TFTs is associated with LDH and D-dimer which are indicators of cell and endothelial damage, duration of hospitalization, clinical severity, and having mutant strains and it has been concluded that low TSH can be used as a prognostic indicator in COVID-19 patients. Further studies with healthy control groups, quantitative RT-PCR tests, histological and pathological correlations, and long-term follow-up are needed.

FNA diagnosis of poorly differentiated thyroid carcinoma. A review of the recent literature

Poorly differentiated thyroid carcinoma (PDTC) is a follicular cell‐derived tumour that was recognised as a distinct entity by the World Health Organisation in 2004. The natural history and pathological features of PDTC are reported to be intermediate between those of well‐differentiated and undifferentiated (anaplastic) thyroid carcinomas. Preoperative identification of PDTC could facilitate better initial patient management in many cases, namely more extensive surgery, without any delay. However, according to some experts, a diagnosis of PDTC can only be rendered on histologic specimens based on criteria recommended in the Turin proposal. Although high‐grade features (namely necrosis and mitoses) can be recognised in FNA material, other cytomorphological features have limited value for the preoperative diagnosis of PDTC and specific features for a definitive diagnosis of PDTC have not yet been clearly defined. Here, we review the current status and future prospects for cytological recognition of PDTC; we emphasise the features that should raise suspicion of this rare condition in FNA cytology and provide an update on molecular features and management of PDTC. Despite proposed histological criteria for the diagnosis of PDTC, its recognition on routine thyroid cytology presents a notable challenge. Current and future advances in molecular testing could contribute to the cytological diagnosis of PDTC.
