Pediatrics in 21st Century and Beyond

Pediatrics is a dynamic discipline and there is awareness and hope for actualizing outstanding achievements in the field of child health in 21st century and beyond. Improved lifestyle and quality of children's health is likely to reduce the burden of adult diseases and enhance longevity because seeds of most adult diseases are sown in childhood. Identification and decoding of human genome is expected to revolutionize the practice of pediatrics. The day is not far off when a patient will walk into doctor's chamber with an electronic or digital health history on a CD or palmtop and a decoded genomic constitution. There will be reduced burden of genetic diseases because of selective abortions of "defective" fetuses and replacement of "bad" genes with "good" ones by genetic engineering. Availability of totipotent stem cells and developments in transplant technology are likely to revolutionize the management of a variety of hematologic cancers and life-threatening genetic disorders. The possibility of producing flawless designer babies by advances in assisted reproductive technologies (ARTs) is likely to be mired by several ethical and legal issues.The availability of newer vaccines by recombinant technology for emerging infective and for non-infective lifestyle diseases is likely to improve survival and quality of life. There is going to be a greater focus on the "patient" having the disease rather than "disease" per se by practicing holistic pediatrics by effective utilization of alternative or complementary strategies for health care. Due to advances in technology, pediatrics may get further dehumanized. A true healer cannot simply rely on technology; there must be a spiritual bond between the patient and the physician by exploiting the concept of psycho-neuro-immunology and body-mind interactions. In the years to come, physicians are likely to play "god" but medicine can't achieve immortality because anything born must die in accordance with nature's recycling blueprint. The medical science is likely to improve longevity but our goal should be to improve the quality of life.

The role of nucleic acid amplification and detection in the clinical microbiology laboratory

Clinical microbiology is in the midst of a new era. Methodology that is based on nucleic acid detection has slowly appeared in the diagnostic laboratory, and is revolutionizing our ability to assist physicians in the diagnosis and management of patients suffering from infectious diseases. Much like the introduction of immunoassays built around hybridoma technology in the 1980s, considerable doubt and promise exist hand in hand in the 1990s. Conventional testing that is technically straight forward, informative, and timely will always be a part of clinical microbiology; however, considerable room for improvement exists with organisms/diseases for which laboratory methods are limited. Nucleic acid methodology will have its greatest and long-awaited impact in this arena.
