Background: Previous studies have shown that tourniquet (TQ) during total knee arthroplasty (TKA) is associated with nerve injury and deep vein thrombosis. However, it is still not clear whether TQ which is effective in decreasing intraoperative blood loss and creating a bloodless surgical fields, is beneficial in management during and after TKA.
Methods: We compared intra- and postoperative management of patients undergoing TKA with (Group T, n = 41) and that without a TQ (Group N, n = 40) at Toyama Prefectural Central Hospital.
Results: The intraoperative blood loss in group T was less than that in group N, but perioperative blood loss showed no significant defference between the two groups. Pain and nerve injury between the two groups were comparable for 24 hours postoperatively. There was no significant defference in the incidence of DVT, and no pulmonary thromboembolism occurred.
Conclusions: Using a TQ which could not decrease the amount of perioperative blood loss did not affect the incidences of postoperative pain, nerve injury and, risk of DVT between the two groups.

This article highlights the critical importance of identifying the classic triad of hemoptysis, anemia, and diffuse pulmonary infiltrates, offering clinicians a structured approach for the timely diagnosis and management of the diffuse alveolar hemorrhage in setting of GPA. Post-intubation HRCT findings revealed diffuse patchy ground glass opacities in both lungs, along with right lobar consolidation showing liquefaction and an air-fluid level.

Short stature, joint hyperextension, ocular hypotension, Rieger abnormalities, and delayed tooth eruption (SHORT) syndrom is a rare primary autosomal dominant genetic disorder mainly caused by pathogenic loss-of-function variants in the phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1) gene. We report the case of a Chinese adult female patient with SHORT syndrome, carrying a PIK3R1 gene variant (c.1945C > T), who developed abnormal glucose metabolism and severe postprandial insulin resistance over 9 years.

Inappropriate birth weight for gestational age (IBWGA) is linked with obstetric complications like birth asphyxia, hypothermia, and postpartum hemorrhage. This study was aimed at determining the prevalence of IBWGA with factors associated with newborns born at Dessie Referral Hospital, northeast of Ethiopia. We used a retrospective cohort study design and systematic random sampling method to select charts of women giving birth at the hospital from January 2013 to December 2017.

We present a highly challenging case of brainstem hemorrhage complicated with pneumonia in a 41-year-old male patient. The patient had intermittent and recurrent fever for nearly two months from June 24, 2022 to August 22, 2022, along with extremely unstable vital signs. Multiple consultations were conducted among clinicians and pharmacists.

Microglial-mediated neuroinflammation is crucial in the pathophysiological mechanisms of secondary brain injury (SBI) following intracerebral hemorrhage (ICH). Mitochondria are central regulators of inflammation, influencing key pathways such as alternative splicing, and play a critical role in cell differentiation and function. Mitochondrial ATP synthase coupling factor 6 (ATP5J) participates in various pathological processes, such as cell proliferation, migration, and inflammation.
