Déficits immunitaires primaires: diagnostic, prise en charge, quelques perspectives.

Severe primary immunodeficiencies (PID) are rare; their global incidence is comparable to that of childhood leukemia; they include more than 100 different entities. Clinical manifestations are: unusually severe or frequent infections or infections that do not respond to adequate treatment; an increased risk of certain malignancies; sometimes auto-immune manifestations. Delayed diagnosis and management of PID can lead to severe and irreversible complications or to death. PID can become manifest only in the adult; in common variable immune deficiency, the median age at diagnosis is between the 2nd and the 3rd decade of life. PID are often transmitted genetically; recent progresses in molecular biology have allowed more precise and earlier, including antenatal, diagnosis. Molecular treatment of 3 infants with a severe immunodeficiency has recently been achieved in April 2000. Those progresses were mostly based on the study of immunodeficiency databases. We present here the work of a Belgian group specialized in PID; meetings have started in June 1997. This group establishes guidelines for the diagnosis and treatment of PID, adapted to the local situation. The elaboration of a national register of PID is also underway; this has to provide all guaranties of anonymity to patients and families. Such a register already exists at the European level; it has provided the basis for new diagnostic and therapeutic possibilities. The inclusion of Belgian data in this register should allow essential progresses essential for our patients.

Preliminary experience of ovarian tissue cryopreservation procedure: alternatives, perspectives and feasibility

Chemotherapy and radiotherapy induce premature ovarian failure in many patients treated for oncological or benign diseases. The present paper reviews the risk of developing premature ovarian failure according to the type of treatment and the different options to preserve fertility, focusing on the cryopreservation of ovarian tissue. This technique constitutes a promising approach to preserve the fertility of young patients and offers the advantage of storing a large number of follicles that could be subsequently transplanted or cultured in vitro to obtain mature oocytes. Based on 34 requests, from which 19 were performed, the feasibility of the ovarian cryopreservation procedure is evaluated. The medical and ethical approaches of this protocol are also discussed. Cryopreservation of ovarian tissue constitutes new hope for many patients, but must still be kept for selected cases, with a significant risk of premature ovarian failure after treatments such as bone marrow transplantation.

The Harsh Reality of Pursuing Innovations: Emerging Market Perspectives

This short conference paper serves as a distillation of a keynote address delivered at the the Second National Conference on Management and Higher Education Trends & Strategies for Management & Administration hosted by Bangkok-based Stamford International University (Thailand) on November 1, 2014.Innovation is discussed as the heart of entrepreneurial processes occurring in today's capitalist economic systems, including transition economies like China and Vietnam, which underscores economic competitiveness of firms and economies. But the innovation effort and process also face dilemma of "entrepreneurial curse of innovation". Advantages and disadvantages are weighed for a more balanced view, especially in the context of outnumbering SMEs and given existence of pitfalls and traps along the innovation path of development. Toward the end, the value of the market is once again stressed amid the concern of subjective assumption and illusion about availability of market opportunities in the mind of innovators, which may contrast totally with the dismal outcome the actual market realities may show ex post.
