Background: This study reviewed the accuracy of fine-needle aspiration biopsy (FNAB) and the efficacy of thyroid suppression for colloid nodules in our population to determine the utility of these two modalities on the decision to operate.
Methods And Materials: A retrospective chart review of patients with colloid nodules diagnosed by FNAB from January 1993 to July 1995 was conducted. A 52-patient cohort underwent surgical management, and their needle aspirate cytologies and final pathologies were reviewed.
Results: A 7.7% false-negative rate in the detection of thyroid malignancy by FNAB was obtained. This is in keeping with data reported in the literature. Virtually no efficacy of hormonal suppression in our population was found.
Conclusion: When the literature is reviewed and compared with the results of this study, the use of FNAB as a decision tool to operate is valid. The decision to operate based on the outcome of hormonal suppression, however, is not valid based on our results.

The imbalance of redox homeostasis, especially the abnormal levels of reactive oxygen species (ROS), is a key obstacle in the bone repair process. Therefore, developing materials capable of scavenging ROS and modulating the microenvironment of bone defects is crucial for promoting bone repair. In this study, to endow poly(amino acids) (PAA) and its composites with anti-oxidative stress properties and enhanced osteogenic differentiation, we designed and prepared a calcium sulfate/calcium hydrogen phosphate/poly(amino acids) (PCDM) composite material with a thioether structure (-S-) in the molecular chain of PAA matrix through situ polymerization and physical blending method.

Introduction: Shear wave elastography (SWE) is an ultrasound diagnostic method used to measure tissue stiffness. Since the mechanical properties of tissue involved in the pathological process change, SWE might indicate regions of the examined tissue covered by the disease. It is well documented that SWE helps to differentiate benign and malignant nodules in thyroid glands in adults, however, there are few studies on the application of SWE in thyroid diagnosis in children.

The mechanical properties and bioactive motif densities of extracellular matrix materials play crucial roles in regulating cell behaviors, such as cell adhesion, migration, proliferation, and differentiation. However, current studies on cellular responses to ECM predominantly concentrated on polymer hydrogels featuring a single factor, such as the mechanical strength, the types of bioactive motifs, and the morphology of the polymers. This limited focus may overlook the complex interplay of multiple factors.

Introduction: Indeterminate oncocytic/Hürthle cell lesions on thyroid cytology are reflexed to molecular testing. This study aims to examine the cytologic characteristics of thyroid fine-needle aspiration (FNA) smears with oncocytes classified as atypia of undetermined significance (AUS) with particular molecular patterns that can aid in determining a more conclusive Bethesda category upfront thus decreasing unnecessary testing and associated costs.
Materials And Methods: Our pathology database was searched for thyroid FNAs with AUS for oncocyte predominance from 2019 to 2022.

Article Synopsis
- Pulmonary colloid adenocarcinoma is a rare type of lung cancer, making its clinical features largely unknown; this report details a case of early-stage recurrence post-surgery.
- A 68-year-old man was found to have colloid adenocarcinoma after a shadow was detected on a chest X-ray, leading to surgery where the cancer was initially removed and staged as early as possible (IA2).
- Despite the belief that colloid adenocarcinoma has relatively slow progression, the case highlights that it can recur quickly, underscoring the need for following standard treatment guidelines for lung cancer.
