Inherited thrombocytopenias (ITs) are a heterogeneous group of disorders characterized by low platelet count resulting in impaired hemostasis. Patients can have spontaneous hemorrhages and/or excessive bleedings provoked by hemostatic challenges as trauma or surgery. To date, ITs encompass 32 different rare monogenic disorders caused by mutations of 30 genes. This review will focus on the major discoveries that have been made in the last years on the diagnosis, treatment and molecular mechanisms of ANKRD26-Related Thrombocytopenia and MYH9-Related Diseases...

Cardiovascular diseases are the leading cause of death worldwide. Conceptually, endothelial dysfunction, inflammatory status and oxidative stress are at the forefront in the onset and development of most cardiovascular diseases, particularly coronary artery disease and heart failure. Serum albumin, the most abundant plasma protein, has many physiological properties, including anti-inflammatory, antioxidant and antiplatelet aggregation activity. It also plays an essential role in the fluid exchange across the capillary membrane...

BACKGROUND: The aim of this study to evaluate the contributions of titanium-prepared platelet-rich fibrin (T-PRF) combined with open flap debridement (OFD) on biological markers in gingival crevicular fluid (GCF)and periodontal outcomes. METHODS: Twenty-nine participants with chronic periodontitis were treated either with autologous T-PRF+OFD or OFD alone. GCF growth factor levels and relative receptor activator nuclear factor kappa-B/osteoprotegerin (RANKL/OPG) ratio at baseline and 2, 4, and 6 weeks postoperatively were analyzed, and clinical parameters such as probing depth (PD), relative attachment level (RAL) and gingival margin level (GML) at baseline and 9 months after surgery were compared...

Nasal liquorrhea is a serious problem in surgery of skull base tumors, which is associated with a high risk of purulent-septic complications. This paper presents a case of successful repair of a cerebrospinal fluid fistula with an autologous platelet gel in the postoperative period after removal of meningioma of the anterior cranial fossa base, which was accompanied by a purulent-inflammatory complication in the surgical wound area.

Compared to standard component therapy, fresh whole blood (FWB) offers potential benefits to neonates undergoing cardiopulmonary bypass (CPB) in the context of open cardiac surgery: decreased blood loss and subsequent risk of volume overload, improved coagulation status, higher platelet counts during and following CPB, circumvention of limited vascular access, and significantly reduced donor exposures. Obtaining FWB, however, entails 2-5 days of preparation, which often precludes its availability for neonates requiring CPB in the immediate newborn period...

PURPOSE OF REVIEW: Impaired healing outcomes or even non-unions after bone injury are still a highly relevant problem in the daily clinical life. Especially within an aging population, the occurrence of bone fractures increases and thus novel treatment approaches to overcome compromised bone regeneration are needed. RECENT FINDINGS: The gold standard to treat delayed or non-healing bone injuries is still the use of autologous bone grafts to foster regeneration. Besides its successful treatment outcome, it also has disadvantages: a second surgery is needed in order to harvest the bone material and the material is highly limited...

Chronic inflammation is one of the critical causes to promote the initiation and metastasis of solid malignancies including lung cancer (LC). Here, we aimed to investigate the prognostic roles of albumin (Alb)-to-fibrinogen (Fib) ratio (AFR), Fib and Alb in LC and to establish a novel effective nomogram combined with AFR. Four hundred twelve LC patients diagnosed between February 2005 and December 2014 were recruited in this prospective study. The prognostic roles of AFR, Fib, Alb, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and monocyte-to-lymphocyte ratio (MLR) were identified by X-tile software, Kaplan-Meier curve, Cox regression model, and time-dependent ROC...

BACKGROUND: Randomized trials have shown the benefits of injecting bone marrow-derived mesenchymal stem cells (BmMSCs) after standard hip decompression in patients with osteonecrosis of the femoral head. However, the combination of BmMSCs and platelet-rich plasma (PRP) injected into the femoral head after decompression has not been reported previously. This study reports the results in a preliminary series of patients with osteonecrosis of the femoral head treated with BmMSCs plus PRP...

OBJECTIVE: This prospective randomized clinical trial was conducted to determine whether the application of a platelet-rich fibrin (PRF) palatal bandage after harvesting free gingival grafts (FGG) would improve healing of donor sites and decrease pain scores and patient discomfort. MATERIALS AND METHODS: Twenty-four patients received FGG to augment keratinized tissue dimensions. The application of a PRF bandage was decided randomly (n = 12 in each group). Patients reported their pain levels for the first 7 days of healing using the visual analog scale (VAS), 101-point numerical rating scale (NRS-101), and 4-point verbal rating scale (VRS-4)...

BACKGROUND AND OBJECTIVES: The 22q11 deletion syndrome is associated with a wide spectrum of phenotypic features, hence clinical diagnosis is difficult. Individuals with this syndrome are found to have a risk of developing transfusion associated graft-versus-host reaction, if they are given nonirradiated blood. Our aim was to elucidate whether chromosome 22q11 deletion in children with syndromic conotruncal heart defects is associated with platelet abnormality. MATERIALS AND METHODS: The genetic analysis was performed by standard cytogenetic and Fluorescence in situ hybridization technique...
