To the Editor: Scabies is a cutaneous parasitosis transmitted mainly by skin contact. Delayed diagnosis because of atypical presentation facilitates dissemination. Crusted (Norwegian) scabies particularly is likely to lead to epidemics, because patients are infested by thousands of mites and thus are extremely contagious. Several nosocomial scabies outbreaks with secondary cases among the relat...

There have been no reports of serious adverse reactions with the use of topical ivermectin in a limited number of patients (i.e., fewer than 400).1,2 Ivermectin 0.5% lotion does not have the neurotoxicity concerns of lindane or the flammability concerns of malathion (Ovide).2,3 The safety of the lotion has not been established in patients younger than six months, and use in this age group is no...

More than 760 Tampa Bay (Florida, U.S.A.) sediment samples have been analyzed for organic contaminants (PAHs, organochlorine pesticides, and PCBs) since 1993. Data were analyzed to assess status by habitat (defined by overlapping salinity zones and sediment type). The habitats most degraded by PAHs and pesticides were generally located in lower salinity, fine-grained sediment habitats, which ar...

The manufacture and use of trichlorobenzenes as solvents, chemical intermediates, and dye carriers has led to their release into the environment. Trichlorobenzenes may also be released into the environment indirectly from the degradation of higher chlorinated benzenes (tetrachlorobenzene, pentachlorobenzene, and hexachlorobenzene) and the pesticide lindane (γ-hexachlorocyclohexane). They may al...

The paper concern is determination of eight pesticides in food products samples. The target compounds are: Lindane, Heptachlor, Aldrin, o,p-DDE, Dieldrin, Endrin, p,p’-DDT, and Methoxychlor. The compounds quantities were performed from chromatographic area obtained in full scan GC/MS mode after baseline separation and by comparation with surrogate internal standard area (Diphenylamine). The sam...
