Thyroid cytology in pediatric patients: a single-center study from 2015 to 2023-is there a necessity for distinct treatment approaches for patients with and without autoimmune thyroiditis?

The management of thyroid nodules is guided by the cytological classification provided by The Bethesda System for Reporting Thyroid Cytology. Notably, the biology of thyroid tumors in pediatric patients differs from that in adults, and there is limited research focused on pediatric cases. This study aimed to assess the effectiveness of the Bethesda system in pediatric patients treated at the largest tertiary pediatric thyroid center in Poland between 2015 and 2023.

Rationale and feasibility of mucin expression profiling by qRT-PCR as diagnostic biomarkers in cytology specimens of pancreatic cancer.

Background: Aberrantly expressed mucin glycoproteins (MUC) play important roles in pancreatic ductal adenocarcinoma (PDAC), yet their use as a diagnostic aid in fine-needle aspiration biopsy (FNAB) is poorly documented. The aim of this study was to investigate the rationale and feasibility of mucin (MUC1, MUC2, MUC3, MUC4, MUC5AC, and MUC6) expression profiling by RT-PCR for diagnostic applications in cytology.

Methods: Mucin expression was examined by RT-PCR and immunohistochemistry in specimens resected from patients with pancreatic (n = 101), ampullary (n = 23), and common bile duct (n = 10) cancers and 33 with chronic pancreatitis.

Semiquantitative immunohistochemistry for mucin (MUC1, MUC2, MUC3, MUC4, MUC5AC, and MUC6) profiling of pancreatic ductal cell adenocarcinoma improves diagnostic and prognostic performance.

Aims: Mucin (MUC) glycoproteins are involved in various steps of the carcinogenesis and progression of human malignancies. The aim of this study was to verify whether semiquantitative evaluation of MUC staining by immunohistochemistry may help to differentiate pancreatic ductal cell adenocarcinoma (PDAC) from chronic pancreatitis and normal pancreas.

Methods And Results: Mucin expression was examined by immunohistochemistry in surgical specimens resected from 101 patients with PDAC and 33 with chronic pancreatitis, and in 40 normal pancreatic tissue specimens.

Evaluation of Gram-positive rod surveillance for early anthrax detection.

Since 2003, Connecticut laboratories have reported Gram-positive rod (GPR) isolates detected within 32 h of inoculation from blood or cerebrospinal fluid. The objectives were to rapidly identify inhalational anthrax and unusual Clostridium spp. infections, and to establish round-the-clock laboratory reporting of potential indicators of bioterrorism.

An outbreak of concurrent echovirus 30 and coxsackievirus A1 infections associated with sea swimming among a group of travelers to Mexico.

Background: Enteroviruses are shed in human stool and can cause a wide spectrum of illness. They are the leading cause of aseptic meningitis.

Methods: In 2004, the Connecticut Department of Public Health investigated a meningitis cluster among persons returning from a school-organized trip to Mexico.
