Perioperative bleeding can be a serious life-threatening complication in adult patients undergoing cardiac surgery, given the older age and additional comorbidities present in this patient population. The standard treatment options include transfusion of blood components and surgical re-exploration. We report the first case of an elderly female patient treated with local administration of recombinant factor VIIa (rFVIIa) for intractable hemorrhagic pericardial effusion, which developed following a transcutaneous aortic valve replacement (TAVR) procedure for severe aortic stenosis...

Pretransfusion testing is very important to prevent transfusion of incompatible red cells, which might result in a hemolytic transfusion reaction. This includes the detection of antibodies in recipients' serum and compatibility testing between donor cells and recipient serum. The most commonly used methods include gel and tube techniques. We present a case in which an anti-E alloantibody was detected by gel method but not by tube testing. As a result, red cells that were retrospectively phenotyped as positive for E antigen were inadvertently selected and transfused after crossmatch using the same tube method...

M. abscessus complex is notoriously resistant to most antimicrobial agents. The complex is differentiated into 3 subspecies: M. abscessus subsp. abscessus, M. abscessus subsp. massiliense, and M. abscessus subsp. bolletii. Skin and soft tissue infections due to this organism can be acquired by direct contact with contaminated material through traumatic injury, surgical wound and environmental exposure or by secondary involvement of skin/soft tissue during disseminated disease. We report a case of Mycobacterium abscessus infection recovered from a post-operative mid-line abdominal wound to illustrate the diagnostic and management difficulties encountered in such patients...

Health systems face intense pressure to decrease costs and improve services as the health care delivery system in the United States undergoes tremendous change due to health care reform. As health systems grow, like any business, they are forced to explore standardization to realize and maintain efficient practices. Clinical services, such as laboratory medicine, are more difficult to integrate due to wider variation in acceptable practice and culture, compared with other services. However, changes to laboratory service are imperative if health care professionals expect to survive and thrive in the new business environment...

Mastocytosis is a clonal neoplasm with the potential to affect various organs within the body. It can range in clinical severity from benign to extremely aggressive. Mastocytosis can be separated into cutaneous, systemic, and leukemic forms, as well as mast-cell sarcoma and extracutaneous mastocytoma. It is most often an acquired condition but can be inherited; the most commonly identified genetic aberrations leading to mastocytosis are activating mutations involving codon 816 of the KIT gene. Herein, we present the case of a 30-year-old Caucasian man with systemic mastocytosis discovered to have a p...

Histoplasmosis has been observed in patients with immunosuppression in the form of isolated pulmonary involvement and disseminated disease. However, very few cases of this type that involved pleural effusion have been reported, and none have been reported in a case individual with mixed-phenotype acute leukemia (MPAL). Herein, we report a case involving a 23 year old Punjabi man having fever and breathlessness in the postinduction therapy period for mixed-phenotype acute leukemia (MPAL) with diagnosis of histoplasmosis based on the results of pleural fluid cytologic testing...

Many studies have suggested that inappropriate plasma usage is common. An important factor contributing to futile plasma administration in most patients is the nonlinear relationship between coagulation-factor levels and the volume of plasma transfused. In this review, a validated mathematical model and data from the literature will be used to illuminate 3 key properties of plasma transfusion. Those properties are as follows: the effect of plasma transfusion on international normalized ratio (INR) is transient; for the same volume of transfused plasma, a greater reduction in INR is observed at higher initial INRs; and the effect of plasma transfusion on INR correction (ie, the difference between initial and final INRs) diminishes as more plasma is transfused...
