Symptomatic congenital syphilis presenting at birth.

We report here a case of congenital syphilis presenting in a newborn infant at birth. A negative infant VDRL test, pseudoparesis and more notably, joint swellings (arthritis) were features seen uncommonly. Florid skeletal involvement, which is rarely seen in the early neonatal period, prompted us to draw attention to the varied presentation of this disease, rightly referred to as the "master masquerader".

Role of liver and brain lysosomal and mitochondrial enzymes in development of delayed neuropathy in hens by 0,0-diisopropyl phosphorofluoridate.

Subacute dose of 0,0-diisopropyl phosphorofluoridate (DFP), a potent organophosphorus ester capable of producing delayed neurotoxicity (OPIDN), did not produce any significant change in the levels of lysosomal and mitochondrial marker enzymes of brain, liver and serum at any time after treatment in hens protected with atropine. The results suggest the absence of any involvement of mitochondrial and lysosomal enzymes at any stage in the development of OPIDN in susceptible species by treating with DFP.
