Objective: The aim of this study was to assess the effects of tranexamic acid on fracture healing in the rat tibia closed fracture model.

Methods: Sixty-four male Sprague-Dawley rats were included in this study, where closed fracture and intramedullary nailing were performed on their right tibial diaphyses. They were divided into 2 main groups, the experimental group, which was given weekly tranexamic acid injections, and the control group, which received no additional treatment.

Background: Pseudoangiomatous stromal hyperplasia (PASH) is a benign lesion of myofibroblasts that is composed of a network of slit-like channels that resemble vascular spaces. The aims of this study were to document the frequency of PASH in core needle biopsy specimens (CNBS) of the breast, to describe which histopathologic findings coexist with PASH and to examine any endothelial cell differentiation.

Materials And Methods: We reevaluated hematoxylin and eosin-stained sections of all CNBS that were obtained during a 1-year period.

Objective: The aim of this study was to evaluate the impact of the timing of platelet-rich plasma (PRP) application on the healing of Achilles tendon injury in a rat model.

Methods: Fifty-four female Sprague-Dawley rats were divided into 4 groups: PRP preparation group (n=6); Achilles tendon tear and 150 µL of PRP received on the day following the injury (PRP day 0, group 1, n=16); Achilles tendon tear and 150 µL of PRP received on the third day following injury (day 3 , group 2, n=16); Achilles tendon tear and 150 µL of saline received on the day following injury (PRP day 0, group 3, n=16). Rats were sacrificed at 3 weeks.

Chondroblastoma is a highly destructive tumor originating from immature cartilage cells. Although chondroblastoma is defined as a benign tumor, it may exhibit malign tumor behaviors such as invasion or metastasis on neighboring structures. Magnetic resonance (MR) image is a solid mass lesion, which included heterogeneous hypointense in T2A and heterogeneous minimal hyperintense in T1A with destructive expansile characteristics and millimetric calcifications.

Article Synopsis
  • Matrix-producing carcinoma (MPC) is a rare type of breast cancer first identified in 1989, characterized by its direct transition to cartilaginous stroma without the usual spindle cell component.
  • A recent case involved a 43-year-old woman who underwent breast-conserving surgery after a diagnosis of invasive breast carcinoma, later identified as MPC.
  • While the tumor's origin suggests it may come from epithelial cells, its prognosis remains uncertain, highlighting the importance of thorough histopathological evaluation for accurate diagnosis.

Pseudoangiomatous stromal hyperplasia (PASH) is a benign proliferative entity of mammary stroma. It is generally found as an incidental finding. It may rarely present as a palpable nodule.

Primary tumors of the paratesticular region are rare, with paratesticular sarcomas constituting a major proportion of these tumors, particularly in the elderly. The paratesticular region consists of mesothelial, various epithelial and mesenchymal cells and may therefore give rise to a number of tumors with various behaviors. Defining the association between the paratesticular mass and the testicle, and differentiation between benign and malignant masses using radiology is challenging, therefore the mass is usually considered to be malignant and radical orchiectomy with high ligation is performed.

Purpose: Temozolomide (TMZ) has anti-tumor activity in patients with malignant glioma. Hyperbaric oxygen (HBO) may enhance the efficacy of certain therapies that are limited because of the hypoxic tumor microenvironment. We examined the combined effects of TMZ-HBO in a rat glioma model.

Background/aims: Sclerosing cholangitis is a rare complication of Langerhans cell histiocytosis in children which can result in liver failure. This combination is even rarer in adults.

Case Report: We report a 65-year-old female who developed sclerosing cholangitis 4 years after the diagnosis of Langerhans cell histiocytosis.
