BACKGROUND: Acute appendicitis is one of the most common surgical emergencies. An early and accurate diagnosis of acute appendicitis is vital. Evidence for a link between platelets indices and inflammation disease comes from recent studies. We aimed to evaluate preoperative diagnostic values of platelet indices (Mean platelet volume-MPV, Platelet Distribution Width-PDW, Plateletcrit-PCT) and leukocyte count (WBC) in comparison with post-operative histopathology results in patients who underwent appendectomy...

BACKGROUND: It is well accepted that functional activity of platelet integrin αIIbβ3 is crucial for hemostasis and thrombosis. The β3 subunit of the complex undergoes tyrosine phosphorylation shown to be critical for outside-in integrin signaling and platelet clot retraction ex vivo. However, the role of this important signaling event in other aspects of prothrombotic platelet function is unknown. METHOD: Here, we assess the role of β3 tyrosine phosphorylation in platelet function regulation with a knock-in mouse strain, where two β3 cytoplasmic tyrosines are mutated to phenylalanine (DiYF)...

Wiskott-Aldrich syndrome (WAS) is a rare X-linked immunodeficiency characterized by various clinical phenotypes. We report the case of a 3-year-old immigrant boy presenting with persistent infant-onset thrombocytopenia treated for refractory immune thrombocytopenic purpura. Sequence analysis confirmed the diagnosis of WAS. The patient responded neither to IV infusions of immunoglobulin (Ig) nor a thrombopoietin receptor agonist and is currently planned for stem cell transplantation. Raised awareness is thus vital of this potentially misdiagnosed and lethal disorder...

Gaucher disease (GD), an autosomal recessive lipid storage disorder, arises from mutations in the GBA1 (β-glucocerebrosidase) gene, resulting in glucosylceramide accumulation in tissue macrophages. Lyso-Gb1 (glucosylsphingosine, lyso-GL1), a downstream metabolic product of glucosylceramide, has been identified as a promising biomarker for the diagnosis and monitoring of patients with GD. This retrospective, exploratory analysis of data from phase 3 clinical trials of velaglucerase alfa in patients with type 1 GD evaluated the potential of lyso-Gb1 as a specific and sensitive biomarker for GD...

Serial phlebotomy is a common sampling practice for repeated-measures studies in biomedical research. In NHP, the effect of serial blood collection on RBC parameters has been characterized, but the effects on platelet parameters and other aspects of the hemogram have not been well studied. We sought to characterize the circulating platelet phenotype throughout the course of 7 serial phlebotomies spanning 30 d in pigtailed macaques (Macaca nemestrina). Phlebotomy was performed on 23 animals at days 0, 2, 4, 7, 10, 21, and 30 to quantify the circulating platelet count and markers of both hemostatic and immune platelet activation...

BACKGROUND: There is evidence to demonstrate that the coagulopathy which occurs in patients with traumatic brain injury coincides with disseminated intravascular coagulation (DIC). We hypothesized that DIC with increased fibrinolysis during the early stage of isolated traumatic brain injury (iTBI) affects the outcome of the patients and that hypoperfusion contributes to hyperfibrinolysis in the DIC. METHODS: This retrospective study included 92 patients with iTBI who were divided into DIC and non-DIC groups according to the Japanese Association Acute Medicine DIC scoring system...

: Rise in mean platelet volume (MPV) has been demonstrated to be associated with increased platelet reactivity. In diabetes patients, augmented MPV was proposed to contribute to increased risk of thrombotic complications. Therefore, the aim of this study was to investigate whether under hyperglycemic conditions, aldose reductase (AR)-mediated sorbitol formation and associated rise in cell volume, which subsequently results in platelet hyperactivation. Platelets were obtained from 30 healthy volunteers and 13 patients with diabetes...

In this study, we describe a Japanese family with progressive hearing loss and macrothrombocytopenia. Using next-generation and Sanger sequencing analyses, we identified a heterozygous variant in exon 27 of the DIAPH1 gene (NM_005219), c.3637C>T, p.R1213X. All patients in the family had sensorineural hearing loss and macrothrombocytopenia. None of the patients exhibited a tendency to bleed. No pathogenic variants were found in the MYH9 gene. Hearing loss began with high-frequency loss during early childhood and progressed to severe hearing loss involving all frequencies...
