Comparison of classical methods for bone age determination with Capitohamate planimetry on wrist X-rays.

Background/aim: This study aims to compare the Greulich-Pyle (GP) and Tanner-Whitehouse 2 (TW2) methods, both used in left wrist radiography for bone age determination in the pediatric age group, with the Capitohamatum method (CH) due to the importance of determining bone age in the pediatric period.

Materials And Methods: Direct radiographs of 210 female and 291 male individuals between the ages of 0-15 without any pathology in the left wrist bones were obtained; 501 os capitatum and os hamatum on anterior-to-posterior direct graphic images were measured using the GP, TW2, and CH planimetry methods. The estimated age of each measurement was calculated by evaluating the relationship between chronological age and sex.

How much do we know about nanobacteria?

Background/purpose: Nanobacteria, known to date as self-replicating, nano-scale size organisms, smaller than bacteria. However, whether these are living organisms or agglomeration of biomolecules was one of the most controversial issues for many years. One of the reasons for debate is their lack of any genetic material.

Bone Mineral Density in the Scaphoid.

: The scaphoid bone is essential for wrist stability and movement. While fractures commonly occur at the scaphoid's waist, those at the proximal pole, though rarer, tend to result in nonunion, potentially linked to variations in bone mineral density (BMD). Previous studies have shown an increase in BMD at the proximal pole in fractured scaphoids, but BMD distribution in intact scaphoids has not been well studied.

Metagenomic analysis of atheroma plaques for identification of microorganisms indicates presence of Toxoplasma gondii as a possible etiological agent.

Background: Cardiovascular diseases (CVDs) are the leading cause of death worldwide. Vital organs like the heart are affected by the occlusion of blood vessels due to atherosclerotic plaque formation. However, the role of infectious agents has always been an essential subject of investigation.

Comparison of ultrasound findings of papillary thyroid carcinoma subtypes based on the 2022 WHO classification of thyroid neoplasms.

Purpose: The present study aimed to analyze and compare sonographic features of papillary thyroid carcinoma (PTC) subtypes to determine whether ultrasound (US) may aid in differentiating particular subtypes.

Methods: This retrospective study enrolled 133 patients diagnosed with 142 histopathologically proven PTCs as per the fifth edition of the World Health Organization classification of thyroid neoplasms between January 2013 and May 2023. US features based on the American College of Radiology and European Thyroid Imaging and Reporting Data Systems (TIRADS), and histopathological characteristics of nodules were assessed and compared.
