Autologous Blood Stem Cell Transplantation in Hematological Malignancies

Autologous blood stem cell transplants (ABSCT) are increasingly used for the treatment of haematological malignancies. The use of hemopoietic growth factors, in conjunction with stem cell mobilization by chemotherapeutic agents, has permitted successful harvests requir ing only a few leukaphereses; cells mobilized in this manner contain a relatively large number of committed precursors of all lineages, as well as early progenitor cells capable of main taining long-term haemopoiesis. Haematological recovery after ABSCT is rapid, thereby sig nificantly shortening the period of post-chemotherapy neutropenia and thrombocytopenia. Furthermore, blood-derived grafts may contain fewer malignant cells than the bone marrow cells. The preliminary results have been so encouraging that it is envisaged that in myeloma, Hodgkin's disease and non-Hodgkin lymphomas, ABSCT may eventually replace autologous marrow transplantation.     

Pubertal neuromaturation, stress sensitivity, and psychopathology

Normal adolescent development is often accompanied by transient emotional and behavioral problems. For most individuals with postpubertal-onset adjustment problems, there is a resolution by early adulthood and relative stability through the adult life span. But for a minority, adjustment problems escalate during adolescence and portend the development of serious mental illness in adulthood. In this article, we explore adolescent behavioral changes and neurodevelopmental processes that might contribute to stress sensitivity and vulnerability for the emergence of the mental disorders. Of particular interest is the role that hormonal changes might play in the expression of genetic vulnerabilities for psychopathology. Drawing on recent findings from clinical research and behavioral neuroscience, we describe the ways in which postpubertal hormones might alter brain function and, thereby, behavior. It is concluded that there are both activational and organization effects of hormones on the adolescent brain, and these contribute to developmental discontinuities in behavioral adjustment. Implications for adult psychopathology and preventive intervention are discussed.

Breast fat necrosis secondary to warfarin-induced calciphylaxis,a rare mimicker of breast cancer: A case report and a review of literature

Breast fat necrosis (BFN) is usually a benign inflammatory response to breast trauma. However, an extremely rare cause of fat necrosis is calciphylaxis, a calcification of small- and medium-sized arteries causing thrombosis and ischemia. It is classified into (A) uremic (B) nonuremic-induced calciphylaxis. Calciphylaxis has been reported to be encountered in different parts of the body. However, to the best of our knowledge there is only one case in the English literature of BFN 2ry to warfarin-induced calciphylaxis. We report a 65-year-old female, known case of atrial fibrillation on warfarin, presented with a left breast mass of 4-month duration. The mass was painful and progressively enlarging. Examination of the left breast showed 7 × 4 cm mass, spanning from 10-2 o'clock, free from surrounding structures, with preserved overlying skin. However, the mass was not visualized on mammogram. Ultrasound showed a left breast lobulated hypoechoic mass containing a hyperechoic component. Biopsy showed fat necrosis. After 1 month, she presented with ulceration of the overlying skin. After wide local excision, histopathology demonstrated a calciphylaxis-induced fat necrosis. Considering the patient's background, the diagnosis was BFN secondary to warfarin-induced calciphylaxis. Hence, the warfarin was shifted to Rivaroxaban, 6 months follow-up showed no evidence of recurrence. In conclusion, the rarity of nonuremic calciphylaxis is reflected on the delay of diagnosis in some of the reported cases and the lack of grading system used to guide the management of such difficult wounds. However, keeping a high index of suspicion is important whenever such wounds are encountered with presence of risk factors other than end-stage kidney disease.     

Reduced fluconazole susceptibility of Candida albicans isolates in women with recurrent vulvovaginal candidiasis: effects of long-term fluconazole therapy

Fluconazole resistance and resultant failure to control Candida vaginitis (vulvovaginal candidiasis) remains extremely uncommon; however, long-term clinically relevant decrease in fluconazole susceptibility undoubtedly occurs and accompanies prolonged fluconazole chemoprophylaxis. Accordingly, in patients with refractory vaginitis or breakthrough infections due to Candida albicans, in vitro susceptibility testing is essential to optimally manage vaginitis.
