The immunocalization of the small interstitial leucine-rich keratan sulphate proteoglycan lumican was studied in human teeth using a polyclonal antibody towards lumican and a standard indirect peroxidase technique. There was intense labelling for lumican in predentine, with immunopositivity also observed in and around the tubules, around the odontoblasts and in the pulp with a fibrillar distribution. The previous reported ability of lumican to control collagen fibrillogenesis and it putative function in collagen spacing suggest potential roles for lumican in predentine in relation to mineralization.

Developing a financially viable consultation-liaison service.

As reimbursement for psychiatry changes, general hospital psychiatry divisions, specifically consultation-liaison (C-L) services, will take on increasingly important roles. This article shows how a variety of funding mechanisms have applications in different hospital systems. Although every recommendation does not apply to each hospital, certain important contributions that C-L psychiatry can make, such as updating diagnosis-related group codes and enhancing hospital reimbursement for services appropriately delivered, are reviewed. Specific recommendations that may be helpful in various hospital systems are offered that, individually and in the aggregate, should enhance the position, as well as the financial, research, and clinical base for an effectively managed C-L service.
