Trichotillomania and the mourning process: a case report and review of the psychodynamics

We present our theory of trichotillomania (hair pulling) as a manic phenomenon, complementary to its classic comprehension as a mourning response. Under certain conditions, separation or threat of separation can generate sadness or grief, while in pathological cases, when the loss is experienced as unbearable, the response might be depressive or manic. We suggest that in trichotillomania (TR), like in mania, manic defenses are used to cope with separation. We believe hair pulling is an expression of primary magical thinking, offering the subject an illusion of control and victory over the object. A representative case of a young woman suffering from bipolar disorder with TR is described. Based on our case analysis, we argue that TR may not necessarily be a variant of OCD, but rather classified among the affective disorders.

N-nitrosodibenzylamine in boneless hams processed in elastic rubber nettings

Boneless hams processed in elastic rubber nettings contain high levels of nitrosamines in the outermost layer. The precursors of the nitrosamines are zinc dibutyl- or dibenzyldithlocarbamate used as a vulcanizing agent in the formulation of the rubber. The outermost layer from 59 commercial hams was analyzed for 11 volatile nitrosamines including N-nitrosodibutylamine (NDBA) and N-nitrosodibenzylamine (NDBzA). The principal nitrosamine, NDBzA, was detected in 32 (54%) ham samples at the 10-100 ppb range; it exceeded 100 ppb in 18 (30%) samples, with the highest at 512.2 ppb. No nitrosamine was detected in 7 of 59 ham samples. To determine the cause of the high NDBzA values, various types of unused nettings (from different manufacturers) accompanying the samples were analyzed for nitrosamines. No correlation was found between the NDBzA content of the hams and the nettings. The results suggest that the problem of nitrosamine formation in these products has not yet been resolved.
