Background: The growth of Diabetes Mellitus (DM) is a serious public health issue which is more prevalent in developing countries. The main problems related to DM are the gradual changes in the structural and functional integrity of tissues caused by hyperglycemia, which calls for early diagnosis and periodic monitoring exams. Recent studies suggest that the quality of the nail plate has great potential to assess the secondary complications of DM. Hence, this study aimed to determine the biochemical characteristics of the nails of individuals with DM2 by Raman confocal spectroscopy (CRS).
Methods: We collected fragments from the distal region of the fingernails of 30 healthy volunteers and 30 volunteers with DM2. The samples were analyzed by CRS (Xplora - Horiba) coupled to a 785 nm laser.
Results: Alterations in different biochemical components, such as proteins, lipids, amino acids, and final agents of advanced glycation, and alterations in the disulfide bridges, which are important in stabilizing keratin in nails were identified.
Conclusion: The spectral signatures and new DM2 markers in nails were identified. Therefore, the possibility of acquiring biochemical information by evaluating the nails of diabetics, a simple and easily acquired material associated with the CRS technique, may allow health complications to be detected quickly.

Background: Digitally Enhanced Hands-on Surgical Training (DEHST) platform was introduced to overcome the lack of training capabilities for the challenging task of freehand distal interlocking of intramedullary nails. It demonstrates high perceived realism for surgeons, and novices perform significantly better after DEHST training. However, characterization of how performance improves remained unexplored.

Traditionally, dermatological education emphasizes hair, skin and nails in its curriculum. There is a practice gap with regard to knowledge of normal oral mucosa variants, performance of the oral examination, and competence in diagnosing and treating oral mucosal disorders. The oral mucosa falls within the purview of dermatology.

: Hip fractures are prevalent among the elderly and impose a significant burden on healthcare systems due to the associated high morbidity and costs. The increasing use of intramedullary nails for hip fracture fixation has inadvertently introduced risks; these implants can alter bone elasticity and create stress concentrations, leading to peri-implant fractures. The aim of this study is to investigate the outcomes of peri-implant hip fractures, evaluate the potential causes of such fractures, determine the type of treatment provided, assess the outcomes of said treatments, and establish possible improvement strategies.

Lichen planus (LP) is a chronic inflammatory disease that can present with significant morbidity, particularly in children. Erosive lichen planus (ELP), its rare destructive subtype, can be particularly difficult to diagnose and manage. We present a rare pediatric case of ELP with multisite involvement and discuss the differential diagnosis.
