Correlation between US-FNAC with BRAF V600E Mutation Analysis and Central Neck Lymph Node Metastasis in cN0 Papillary Thyroid Cancer.

Biomed Res Int 2021 1;2021:9937742. Epub 2021 Jul 1.

Department of Ultrasound Medicine, Gansu Provincial Hospital, Lanzhou 730000, China.

The aim of this study was to explore the correlation between ultrasound-guided fine-needle aspiration cytology(US-FNAC) combined with BRAF V600E mutation analysis and central neck lymph node metastasis in cN0 papillary thyroid cancer, so as to provide reliable molecular evidence to use it for preoperative evaluation, operation procedure design, and postoperative follow-up planning in clinic. Specimens were obtained from 250 patients with cN0 thyroid cancer (TI-RADS≥4a, highly suspected of PTC by US-FNAC) after bilateral thyroidectomy and central neck lymph node dissection with accessible postoperative pathologic results of PTC and central neck lymph nodes and used for cytological diagnosis by H&E stain and BRAF V600E mutation detection. Single-factor analysis showed that differences between the central neck lymph node metastasis and nonmetastasis groups were statistically significant in gender, BRAF V600E mutation, and extracapsular extension.

Diagnostic Concordance of Cytology and Histology in Samples Obtained via Endoscopic Ultrasound-Guided Fine-Needle Biopsy (EUS-FNB).

Cureus 2021 Jun 11;13(6):e15596. Epub 2021 Jun 11.

Gastroenterology and Hepatology; Advanced Endoscopy, University of Miami Miller School of Medicine, Miami, USA.

Introduction Endoscopic ultrasound (EUS)-guided fine-needle aspiration and biopsy (FNA/FNB) to obtain cytological aspirates and histological core samples, respectively, are the standard of care for diagnosing lesions in/adjacent to the upper/lower gastrointestinal tract. Due to the lack of standardization of tissue processing, it is unclear whether core samples should be sent only for histology (formalin) or cytology (CytoLyt), or both. The aim of this study was to investigate the diagnostic concordance rates between cytology and histology on EUS-FNB core samples. Read More

Development and validation of a clinical prediction model for endocervical curettage decision-making in cervical lesions.

BMC Cancer 2021 Jul 13;21(1):804. Epub 2021 Jul 13.

Department of Obstetrics and Gynecology, the Second Hospital of Shanxi Medical University, Taiyuan, 030001, Shanxi, China.

Background: In the absence of practical and reliable predictors for whether the endocervical curettage (ECC) procedure should be performed, decisions regarding patient selection are usually based on the colposcopists' clinical judgment instead of evidence. We aimed to develop and validate a practical prediction model that uses available information to reliably estimate the need to perform ECC in patients suspected of having cervical lesions.

Methods: In this retrospective study, 2088 patients who underwent colposcopy, colposcopically directed biopsy (CDB) and ECC procedures between September 2019 and September 2020 at the Second Hospital of Shanxi Medical University were included. Read More

Comparison of the diagnostic effectiveness between an expert and a student in the diagnosis of sarcoidosis by transbronchial biopsy of mediastinal lymph nodes under the control of endosonography.

Adv Respir Med 2021 ;89(3):241-246

Department of Lung Diseases and Tuberculosis, School of Medicine with the Division of Dentistry in Zabrze, Medical University of Silesia, Katowice, Poland.

Introduction: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) of mediastinal lymph nodes is currently considered to be the most effective minimally invasive diagnostic method in patients with suspected stage I and II sarcoidosis. However, diagnostic effectiveness depends on the experience and skills of the doctor which is dependent on the number of correctly performed procedures. The aim of the study is to compare the diagnostic effectiveness of the EBUS-TBNA test obtained by an expert in this field vs that of his student. Read More

Protection measures against SARS-CoV-2 infection for cytopathology and histopathology laboratories personnel: practical recommendations.

Rom J Morphol Embryol 2020 Oct-Dec;61(4):1067-1076

Department of Surgery II, Faculty of Medicine, Grigore T. Popa University of Medicine and Pharmacy, Iaşi, Romania; Socola Institute of Psychiatry, Iaşi, Romania;

In the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, healthcare workers are at high risk to be infected with this new coronavirus, particularly when they handle not only patients, but also their body fluids. In Romania, even though the protective measures to be used by medical staff in emergency departments, clinical departments, radiology departments, clinical laboratories and morgues services are well known, there is little information about the protection of medical staff in the laboratories of cytopathology and histopathology. In this article, we will discuss the transmission routes of the new coronavirus, the surfaces it could contaminate in a hospital, as well as the modalities of its inactivation. Read More

'Rollover' abdominal paracentesis versus standard technique: protocol of a crossover randomized comparative trial.

Future Oncol 2021 Jun 22. Epub 2021 Jun 22.

Department of Internal Medicine, Postgraduate Institute of Medical Education & Research, Chandigarh, 160012, India.

The sensitivity of single abdominal paracentesis for diagnosis of peritoneal carcinomatosis in patients with malignant ascites is 40-70%. Tumor cells shed from the peritoneum settle preferentially in certain recesses of the peritoneum. We aim to compare the standard technique of abdominal paracentesis versus a rollover technique in a randomized crossover study to assess the cytological yield in patients suspected to have peritoneal carcinomatosis.

Imprint cytology: Invaluable technique to evaluate fresh specimens received in the pathology department for Lymphoma workup.

Cancer Cytopathol 2021 May 20. Epub 2021 May 20.

Department of Pathology, McGill University, Montreal, Canada.

At the time of intraoperative consultation, cytologic preparations including smears and imprints can be used in combination with frozen sections to increase diagnostic yield; however, these simple and rapid techniques are not adopted by all pathologists and their use varies considerably between institutions. In patients under investigation for suspected lymphoma, optimal triaging of tissue received fresh in pathology for lymphoma workup is paramount to maximize the odds of obtaining an accurate and clinically meaningful diagnosis and to avoid the need for additional procedures and delays in management, particularly in the current context in which core biopsies have become common practice as a first attempt to attain this goal. Imprint cytology is invaluable in this regard, also as these patients may not have a lymphoma but rather one of its clinical mimics. Read More

Incidence of microcarcinoma and non-microcarcinoma in ultrasound-found thyroid nodules.

BMC Endocr Disord 2021 Mar 4;21(1):38. Epub 2021 Mar 4.

Department of Endocrinology, The Second Affiliated Hospital, Guangzhou Medical University, No.250 Changgang Road East, Haizhu District, 510260, Guangzhou, China.

Backgrounds: The incidence of thyroid nodules is increasing year by year around the world. However, ultrasound is not recommended as a screening test for the general population or patients with a normal thyroid on palpation by the American Association of Clinical Endocrinologists (AACE). In practice, some individuals with normal thyroid palpation have nodules that can just be found out by ultrasound. Read More

Consensus study on the health system and patient-related barriers for lung cancer management in South Africa.

PLoS One 2021 11;16(2):e0246716. Epub 2021 Feb 11.

Division of the Wits Health Consortium, Non-Communicable Diseases Research (NCDR), Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, South Africa.

Background: Lung cancer is the highest incident cancer globally and is associated with significant morbidity and mortality particularly if identified at a late stage. Poor patient outcomes in low- and middle-income countries (LMIC's) might reflect contextual patient and health system constraints at multiple levels, that act as barriers to prevention, disease recognition, diagnosis, and treatment. Lung cancer screening, even for high-risk patients, is not available in the public health sector in South Africa (SA), where the current HIV and tuberculosis (TB) epidemics often take precedence.
