Objective: The objective of this study was to investigate the diagnostic accuracy of visual assessment of the trabecular pattern in intraoral periapical radiographs to identify female subjects at risk of having osteoporosis.
Study Design: Six hundred female subjects underwent intraoral periapical radiography of the maxillary and mandibular premolar region. Five observers assessed the trabecular pattern as dense, heterogeneous, or sparse, with the aid of reference images. All patients received a central dual energy x-ray absorptiometry (DXA) examination of the hip and lumbar spine.
Results: With sparse trabecular pattern as indicative of osteoporosis, mean specificity was high (91.6 for the upper jaw and 90.8 for the lower jaw) while the sensitivity was low (28.2 for the upper and lower jaw). The mean intraobserver agreement was comparable for radiographs of the upper and lower jaw (median kappa(w) 0.53 and 0.57, respectively).
Conclusion: Visual assessment of the trabecular pattern in intraoral periapical radiographs of premolar regions is a potential method to identify women at risk of having osteoporosis.

Metastasis of clear cell renal cell carcinoma to hyalinizing trabecular tumor of the thyroid: A case report.

Department of Pathology, Beilun District People's Hospital of Ningbo City, Ningbo, Zhejiang 315000, P.R. China.
Renal cell carcinoma (RCC) is the most common malignancy that metastasizes to the thyroid; however, metastasis of RCC to a primary tumor of the thyroid is rare. The present study reports the case of RCC that had metastasized to the primary thyroid tumor; namely, a hyalinizing trabecular tumor (HTT). Notably, the RCC was resected 2 years prior.

Background: Indications for primary total knee arthroplasty (TKA) have become more inclusive of morbidly obese patients, however, higher rates of complications and lower implant survival have also been reported in this population. The purpose of this study was to investigate the mid-term survival, clinical, and radiographic outcomes of a cementless trabecular metal monoblock tibial component in severely obese patients.
Methods: This was a retrospective study of class II and III obese (BMI > 35) patients who received a cementless primary TKA.
Biomechanical behavior of cantilevered 3-unit implant-supported prostheses made of PEKK and monolithic zirconia: A finite element study.

Article Synopsis
- The study aimed to assess the biomechanical performance of different designs of three-unit implant-supported prostheses using two materials (Zirconia and PEKK) under various loading conditions.
- Three models were created with different implant placements to analyze three designs: distal cantilever, fixed-fixed, and mesial cantilever, utilizing finite element analysis for stress evaluation.
- Results indicated that the fixed-fixed design performed best, with PEKK showing lower stress in some areas but higher stress in others compared to Zirconia, highlighting the importance of design and material choice in prosthodontics.
An anatomical investigation of alkaptonuria: Novel insights into ochronosis of cartilage and bone.

Ochronotic pigmentation of connective tissue is the central pathological process in the rare metabolic disease alkaptonuria (AKU). Tissue pigmentation in AKU occurs due to unmetabolised homogentisic acid (HGA) in the circulation, caused by an enzyme deficiency in the liver. Ochronotic pigmentation, derived from HGA, has previously been reported and described in large joints obtained from arthroplasty surgeries, which typically have advanced disease.

Objective: To elucidate the mechanisms underlying diabetic osteoporosis, we conducted a comprehensive histological examination of the femora of Spontaneously Diabetic Torii-Lepr (SDT-fa/fa) rats, an established model of obesity-related type 2 diabetes.
Materials And Methods: Femora from 12 30-week-old male SDT-fa/fa rats and age-matched Sprague-Dawley (SD) rats (controls) were used for detailed histochemical analyses, including tartrate-resistant acid phosphatase (TRAP), cathepsin K, alkaline phosphatase (ALP), phosphoethanolamine/ phosphocholine phosphatase 1 (PHOSPHO1), dentin matrix protein (DMP)-1, matrix extracellular phosphoglycoprotein (MEPE), sclerostin, osteocalcin staining, silver impregnation, von Kossa staining, and micro-computed tomography (CT).
Results: Micro-CT and hematoxylin-eosin staining demonstrated significantly reduced trabecular bone volume in the femoral metaphyses of SDT-fa/fa rats.
