A previously healthy youth who had sustained severe head trauma and had received steroids and broad-spectrum antimicrobial agents developed a cranial zygomycotic infection with Saksenaea vasiformis. This is the first time this zygomycete has been implicated as a disease agent. Early identification of the fungal infection and subsequent vigorous medical and surgical therapy led to recovery.

SynopsisModified polyethyleneimine products are hydrophobic with products from monohalotin reactants soluble in HMPA, DMSO, CHC13, and 2,4-pentanedione, while products from dihalotin reactants are insoluble in all solvents. Antifungal activity varies markedly with the nature of the tin moiety. For products from triphenyltin chloride, antifungal activity is widespread and suitable to about 40 ppb of the polymer, which is clearly acceptable for medical and industrial uses. Thus, such modified polymers can be used as retarders of fungi related rot and mildew. The products show moderate high-temperature stabilities.
