We report a rare case of acquired vitamin K deficiency presenting with severe menorrhagia and without any gynecological problem. Partial thromboplastin time (59.2 seconds) and prothrombin time (33.1 seconds, INR: 5.97) were considerably prolonged in laboratory evaluations. A complete coagulation factor assay test was performed for the patient: factor IX, 24%; factor II, 41%; factor VII, 3%; and factor X, 52%. She had been taking many high-energy drinks and she had inadequate dietary intake for the past 6 months...

Critical clinical questions remain unanswered regarding diagnosis and management of patients with Low VWF levels (30-50 IU/dL). To address these questions, the Low VWF Ireland Cohort (LoVIC) study investigated 126 patients registered with Low VWF. Interestingly, despite their marginally reduced plasma VWF levels, ISTH BAT and Condensed MCMDM-1 VWD scores both confirmed significant bleeding phenotypes in the majority of LoVIC patients. For example, among female patients with Low VWF, 77% had ISTH BAT scores ≥6...

The purpose of this systematic review and meta-analysis was to assess the 30-days safety (bleeding and vascular events) and efficacy (reduction in major stroke, myocardial infarction and mortality) of single anti-platelet (SAPT) versus dual anti-platelet (DAPT) after transcatheter aortic valve implantation (TAVI). We used a meta-analytic method with Mantel-Haenszel methods to calculate the odds ratio (OR) and 95% confidence interval (CI). Only randomized clinical trials that compared 30-days safety and efficacy based on Valve Academic Research Consortium criteria were included...

Factor V congenital deficiency is a rare coagulation disorder initially described by Owren in 1947 and known as para hemophilia. It is transmitted through autosomal-recessive inheritance and homozygous cases are usually symptomatic. Factor V is an essential cofactor in the conversion of prothrombin to thrombin by activated factor X. In the absence of factor V, thrombin generation is slowed down and fibrin formation is delayed. This results in a bleeding tendency. We report a case of factor V congenital deficiency in an infant with recurrent epistaxis...

OBJECTIVE: To report a new family with congenital FX deficiency. PATIENTS AND METHODS: The proposita is a 41 years old female with a moderate bleeding tendency (easy bruising, menorrhagia). Parents were not consanguineous. Family history was positive for a mild bleeding tendency. RESULTS: Coagulation and genetics studies revealed that the proposita and two of her siblings were heterozygotes for a new mutation Cys241Gly in exon 6 but had different FX level (2-3% of normal in the proposita and about 50% in the two siblings...

An 80-year-old man presented to our hospital with complaints of tarry stool and shortness of breath. A blood test confirmed marked anemia. On abdominal contrast-enhanced computed tomography, neither hemorrhagic lesions nor tumorous lesions could be pointed out. Upper gastrointestinal endoscopy revealed multiple erythematous flat elevated lesions, which were about 10mm in diameter, located between the stomach and the horizontal part of the duodenum. Colonoscopy revealed similar lesions throughout the entire colon...

BACKGROUND: The incidence of venous thromboembolism (VTE) is about 4-10% in lung cancer patients. Huisheng oral solution (HSOS) has been previously demonstrated to inhibit carageenan induced acute thrombosis in rats, reduce the incidence of thrombosis in the lungs and mesentery of tumor-bearing mice and inhibit tumor cell metastasis. The purpose of this study was to assess the anticoagulant effect of HSOS in lung cancer patients in the perioperative period. METHODS: This study was a multicenter, randomized, single-blind, blank-controlled clinical trial...

Antithrombotic medications target coagulation factors. Their use is associated with an increased bleeding risk. Safer drugs are needed. The heat shock protein 70 (Hsp70) exhibits antithrombotic properties that do not influence bleeding. By using murine models, we aimed to test the hypothesis that overexpressing Hsp70 with CM-695, a first in class dual inhibitor of HDAC6 and phosphodiesterase 9, protects against thrombosis while leaves bleeding tendency unaltered. CM-695 was used to induce Hsp70 overexpression...

Gene therapy provides hope for a cure for patients with haemophilia by establishing continuous endogenous expression of factor VIII or factor IX following transfer of a functional gene copy to replace the haemophilic patient's own defective gene. Haemophilia may be considered a 'low hanging fruit' for gene therapy because a small increment in blood factor levels (≥2% of normal) significantly improves the bleeding tendency from severe to moderate, eliminating most spontaneous bleeds. After decades of research, the first trial to provide clear evidence of efficiency after gene transfer in patients with haemophilia B using adeno-associated viral (AAV) vectors was reported by our group in 2011...

BACKGROUND: New-generation (NG) valves for transcatheter aortic valve implantation (TAVI) has recently been widely used in real-world practice, yet its comparative outcomes with early-generation (EG) valves remain under-explored. METHODS: An electronic literature search using PUBMED and EMBASE was conducted from inception to April 2017 for matched-cohort studies. Articles that compared the outcomes of NG vs. EG valves post TAVI with at least one of the following clinical outcome reported were included: all-cause mortality, major or life-threatening bleeding, major vascular complications (MVC), significant (more than moderate) paravalvular regurgitation (PVR), cerebrovascular events, significant (stage 2 or 3) acute kidney injury (AKI) and new permanent pacemaker implantation (PPI) that occurred either in-hospital or within 30-days...

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...

BACKGROUND Spindle cell oncocytoma (SCO) is a rare nonfunctioning neoplasm of the adenohypophysis, and was first described in 2002. SCO has been categorized as a separate entity by the 2007 World Health Organization (WHO) and is classified as a Grade 1 tumor of the central nervous system (CNS). Review of the literature has shown that 33 cases of SCO have been reported to date, and most of them presented with a mass effect or with panhypopituitarism. However, all reported cases have described the tendency of SCO to be hypervascular on imaging and histology...

Analysis of platelet function is widely used for diagnostic work-up in patients with increased bleeding tendency. During the last decades, platelet function testing has also been introduced for evaluation of antiplatelet therapy, but this is still recommended for research purposes only. Platelet function can also be assessed for hyper-aggregability, but this is less often evaluated. Light transmission aggregometry (LTA) was introduced in the early 1960s and has since been considered the gold standard. This optical detection system is based on changes in turbidity measured as a change in light transmission, which is proportional to the extent of platelet aggregation induced by addition of an agonist...

A 68-year-old man presented with intracranial hemorrhage in the right frontal lobe, which rapidly increased the day after admission. We performed hematoma removal with a biopsy of the cortex around the hematoma. The day after the operation, a subcutaneous hematoma over the craniotomy appeared, and the computed tomography showed a recurrent hemorrhage with an acute subdural hematoma. We were aware of a bleeding tendency, and a detailed hematologic examination by hematologists revealed autoimmune acquired factor XIII deficiency due to an antifactor XIII antibody...

A 3-year-old, female Greater Swiss Mountain dog developed a hemoperitoneum following an exploratory laparotomy and ovariohysterectomy. Platelet count, PT, APTT, and plasma von Willebrand factor antigen concentration were within RIs. A buccal mucosal bleeding time (BMBT) was prolonged. Given the probability of a hereditary thrombopathia, the dog was administered desmopressin, fresh platelet transfusions, and aminocaproic acid to control hemorrhage. Subsequently, DNA testing for the P2Y12 receptor gene mutation identified the dog as being a heterozygote (carrier)...
