Acute respiratory infections are responsible for an estimated 4 million deaths annually worldwide, and are the leading cause of death in children younger than 5 years. Over 1 million people in the United States are hospitalized each year with pneumonia. Mycobacterium tuberculosis infects one third of world’s population. There are more than 1 million tuberculosis-related deaths worldwide each year. Emerging resistance to multiple available antimicrobial agents has hampered the ability to treat tuberculosis and hospital-acquired respiratory infections. The laboratory diagnosis of respiratory infections is an important part of patient management and treatment. In addition to culture isolation of pathogens, advances have been made in a number of non-culture methods. This issue of Clinics in Laboratory Medicinee reviews state-of-the-art laboratory diagnosis of respiratory infections, as well as the testing of susceptibility to antibiotics and antiviral agents. Among some of the respiratory infections covered are: Cystic fibrosis infections; Pertussis; Pharyngitis; Fungal infections. Among the diagnostic tests are: Interferon gamma release assays; Molecuar diagnosis of TB; Urine antigen tests and discussion of Antibiotic resistance in nosocomial respiratory infections.

Molecular pathology has significantly matured over the past decade to establish itself as a discipline in its own right. Patient diagnosis, prognosis, management and care have been influenced by molecular pathology testing algorithms on a global scale. Whether it pertains to carrier status of deleterious genes, diagnosis by molecular techniques, assessment of appropriate remission post treatment, parentage or forensics testing – molecular pathology continues to increase its presence and influence in the diagnostic laboratory armamentarium. Furthermore, intellectualization and proprietization of molecular pathology with respect to the discovery of new genes and or new techniques continues to pose new challenges of test ownership, legalities, liabilities, widespread acceptance and utility. This issue of Laboratory Clinics seeks to provide selective state of the art understanding of molecular pathology with respect to its relationship to key pathology disciplines as well as the current challenges and promise for the future.

The Human Biome is a complex and essential biological system within the human body. The adult human harbors some 100 trillion bacteria in his gut alone. Balance of this system is essential to good health. This issue of Clinics in Laboratory Medicine focuses on treatments to realign this balance as well as advances in understanding the system in general. Topics include: Changes in microbiome in GERD; The relationship of microbiome, inflammation, and colon cancer; Gut microbiome and host genetics in Crohn's disease; Association of oral microbiome with head and neck cancer; The vaginal microbiome-disease, genetics and the environment;, The human virome in children and its relationship to febrile illness; Gut microbiome in irritable bowel syndrome; The neonatal microbiome and necrotizing enterocolitis; Fecal microbiota transplantation for clostridium difficile Infection.

The field of Clinical Microbiology is evolving at a rapid pace, perhaps more so than any other arm of laboratory medicine. This can be attributed to new technology, including high throughput gene sequencing, multiplex molecular assays, rapid evolution of antimicrobial resistance, and discovery of new pathogens. In addition, modern medical procedures, such as solid organ and stem cell transplantation, have resulted in an explosion of infections with agents that historically have been considered to be of low virulence. This issue of Clinics in Laboratory Medicine will highlight some of the advances in diagnostic microbiology, including MALDI-TOF MS, pathogen discovery, and personalized antimicrobial chemotherapy. In addition, one of the papers will focus on implementation of new technologies and how to maximize patient impact of these new methods.
