Alcaptonuria is a hereditary disease, also known as black hip, where there is an accumulation of homogentisic acid pigmentation in joint cartilages. We describe a 74-year-old woman who showed acute destruction of her left hip joint. She received a total hip arthroplasty on her right side in July 2000, and was diagnosed with ochronosis. Her postoperative follow-up was at our institutions outpatient department. She first complained of increasing groin pain in July 2005, after which she had a left total hip arthroplasty in October 2005. Histopathologically, samples from this patient showed "fragmentation and cleft formation" in the cartilage of the femoral head. In addition, the samples revealed a remarkable degradation of proteoglycan, which is the secondary most abundant constituent of extra cellular matrix. These findings suggested that "cleft formation", where cracks develop toward the center, caused an acute destructive arthropathy with morphological fragility suggestive of ochronosis.

Introduction: Perioperative neurocognitive dysfunction (PND) is a significant challenge for patients who need surgery worldwide. Morphine can trigger an intense inflammatory reaction in the central nervous system (CNS) at the same time as analgesia, thus adverse effects aggravating PND. Microglia polarization is closely involved in the regulation of neuroinflammation and the TLR4/MyD88/NF-κB signaling pathway.

Background: In the 21st century, disasters (particularly earthquakes, which remain the leading cause of death) continue to be among the foremost issues requiring global emergency response. While the impact of advancing technologies on the environmental and human damage caused by earthquakes is still a subject of debate, search and rescue (SAR) teams and emergency departments (ED), specifically emergency physicians (EPs), play a crucial role in the most acute management of the effects of these earthquakes on human life. This study aims to examine the injury dynamics of two catastrophic earthquakes that occurred in Turkey 24 years apart from the perspective of EPs, utilizing archival records from the SAR teams in which EPs served.

SUMMARYThe human malaria parasite is known for its ability to maintain lengthy infections that can extend for over a year. This property is derived from the parasite's capacity to continuously alter the antigens expressed on the surface of the infected red blood cell, thereby avoiding antibody recognition and immune destruction. The primary target of the immune system is an antigen called PfEMP1 that serves as a cell surface receptor and enables infected cells to adhere to the vascular endothelium and thus avoid filtration by the spleen.
