Prospects for controlling future pandemics of influenza

Pandemic influenza remains one of the most serious threats to global public health and continued global vigilance to monitor emerging threats is crucial. Of the weapons available to control a pandemic, vaccination is potentially the most powerful, but there are currently serious limitations to timely availability of vaccine supply in an emergency. Many novel influenza vaccines are in development, some of which have the potential to deliver the massive quantities of vaccine that would be required in a pandemic in a short period of time. However, for the foreseeable future, it is likely that the principal vaccine that will be deployed in a pandemic will be an inactivated egg-derived vaccine of the kind that has been available for several decades. This review will focus on the practical hurdles that need to be surmounted to deliver large amounts of safe and effective pandemic vaccine to the general public. There needs to be a continued focus on improvement to the vaccine response system that will require close collaboration between influenza and vaccine experts, manufacturers, regulators and public health authorities around the world.     

The future of the pathologist in the hospital setting

The future of the pathologist in the hospital setting can be speculated on in light of contemporary and predictable trends occurring in hospitals. From five of these trends--downsizing, restructuring, diversification, hospital-physician relations, and for-profit hospitals--eight implications for the practice of pathology are identified.     

Prospects for the development of pre-mortem laboratory diagnostic tests for Creutzfeldt-Jakob disease

At present the diagnosis of Creutzfeldt-Jakob disease (CJD) and related transmissible spongiform encephalopathies in humans is based on clinical criteria and (at post-mortem) the histopathological and immunological examination of brain tissue. The misfolded prion protein, PrPSc, is the single most significant marker, but its recognition by standard serological methods is complicated by its antigenic similarity to the normal prion protein, PrPC. Although there are commercial diagnostic assays available for bovine spongiform encephalopathy using brain specimens taken at slaughter, there are no suitable pre-mortem assays for cattle and none either for pre-mortem human disease. Especially in view of the recent report of variant CJD transmission by blood transfusion, it is important that tests for pre-symptomatic infections are developed. This will safeguard the blood supply and, for example, prevent the transmission of CJD in neurosurgery. This paper reviews the current and prospective approaches to the pre-mortem diagnosis of CJD, in particular its variant form.     

New federal regulations and the future practice of cytology

An explanation of the new federal economic initiatives (the Tax Equity and Fiscal Responsibility Act; diagnosis-related groups) is offered as they currently pertain to the practice of cytopathology. Future trends are discussed, and means to deal with them are recommended. The cytology community can wait no longer to come to grips with changing economic times.     

The future of clinical laboratory database management system]

To assess the present status of the clinical laboratory database management system, the difference between the Clinical Laboratory Information System and Clinical Laboratory System was explained in this study. Although three kinds of database management systems (DBMS) were shown including the relational model, tree model and network model, the relational model was found to be the best DBMS for the clinical laboratory database based on our experience and developments of some clinical laboratory expert systems. As a future clinical laboratory database management system, the IC card system connected to an automatic chemical analyzer was proposed for personal health data management and a microscope/video system was proposed for dynamic data management of leukocytes or bacteria.     

A worm in the cytology laboratory: A root cause analysis case study

In the spring of 2018, nematode‐like organisms were first noted at the time of microscopic diagnosis on gynecologic (GYN) and anal pap specimens in our institution's cytopathology department. Due to their morphology and specimen source, we considered a diagnosis of pinworm. However, after identifying at least 30 more cases over 3 months from patients living in variable locations, we started favoring a contaminant. This report studies the steps that were initiated to figure the source of pap smear‐preparation contamination and the molecular investigation to identify the nature of the contaminant.
