Suicidal age and childhood onychophagia among veterans with personality disorders.
The relationship between childhood onychophagia (finger-nail biting) and the mean age of suicidal and nonsuicidal veterans was investigated among 70 V.A. hospitalized males, diagnosed as personality disorders. The results show that the mean age of suicidal veterans was significantly lower than that of nonsuicidal veterans, and the childhood onychophagia variable, "focal suicide," significantly lowered the mean age of suicidal veterans, but did not significantly lower the mean age of nonsuicidal veterans.
[Behavior therapy of onchophagia and trichotillomania. Ethological and behavioral perspectives].
Emphasis is brought to similarities between informations collected from the study and treatment of patients suffering from nail biting and trichotillomania, by behavioural treatment and the concept according to which such troubles are "tics", learned responses which will become non adapted, present in a given situation, reinforced by time and progressively more resistant to extinction on the one hand, and ethological concepts which consider those behaviours as displacement of activity such as "grooming" in primates, ritual activities, free from nutritions activities, triggered by some attitudes and facilitated by the presence of fear affects, aggressivity or sexual drive.
[The aggressive child (author's transl)].
In children a "normal" aggressiveness should be distinguished from "hostile" and "inhibited" aggression; the latter usually become apparent as heteroaggressive or autoaggressive behaviour. Autoaggression is more common with younger children. Different hypotheses about the origin of aggressiveness are discussed. In the younger child nail biting, trichotillomania, rocking, an intensified phase of contrariness and enkopresis may have components of aggressiveness. In older children and adolescents dissocial forms of development, drug taking, attempted suicid, and anorexia nervosa may be parts of aggressive behaviour. Minimal brain dysfunction, autism, and postencephalitic syndromes predominate amongst organic alterations of the brain as causes for aggressive behaviour. Particularly the Lesch-Nyhan-syndrome, but equally the Cornelia de Lange-syndrome show autoaggressive tendencies.
Predictive value of neuropathic traits.
The classic textbook concepts of neuropathic traits--enuresis, nail-biting, finger-sucking, sleep-walking, anxiety, nightmares, fear of darkness--have been anamnestically recorded in patients in a somatic hospital who were referred for psychiatric interview. More than 50% of the patients could report having had one or more such traits with an even distribution between males and females except for enuresis, which was recorded more frequently in males. The presence of such traits was correlated to adult mental health. No correlation was found between one single trait and later disorders. There was a positive correlation between two or more traits and neurotic states of anxiety or conversion neurosis, but no correlation with depressive disorders or psychosomatic diseases (after Alexander's concept).
Primary peptic ulcer in childhood. Psychosocial, psychological and psychiatric aspects.
Twenty-five children with radiologically confirmed primary peptic ulcers were investigated. All patients suffered from duodenal ulcer and there was an unexpected female preponderance. The frequency of introverted personalities was greater in the patients than in the controls. Five patients suffered from psychiatric disorders, three had histories of suicidal attempts and three reported homosexual experiences. Six patients had nicknames. Eight patients had been operated on for appendicitis. The above parameters were negative in all control cases. The patients had lower mean IQ, worse adaptation to school, more anxious and overprotective parents, higher frequency of faddiness in food and lower frequency of nail-biting than the controls. The onset of symptoms was preceded by psychotraumatic events in eight cases. The findings suggest that the manifestation of the genetic background of duodenal ulcer is strongly influenced by environmental factors and factors associated with the personality of the patients.
Peptic ulcer in childhood. Psychological factors.
Thirty children (20 girls and 10 boys, aged 6-16 years) with primary peptic ulcers, matched in paris for age, sex and socio-economic standard to a group of 30 ulcer-free controls, were submitted to a structured psychiatric interview, a structured 'present psychiatric state' examination and to personality and intelligence tests. With one exception all patients suffered from duodenal ulcer; 3 male patients had personalities with psychopathic elements, 7 patients had nicknames, 5 suffered from psychiatric disorders, 3 had attempted suicide in the past, and 3 had had homosexual experiences. These parameters were negative in all controls. The patients had lower mean IQ, worse scholastic adaptation, more anxious and overprotective parents, higher frequency of faddiness in food and lower frequency of nail-biting than the controls. Psychotraumatic events had preceded the onset of ulcer symptomatology in 11 cases. The findings are discussed and the contribution of psychological factors in the pathogenesis of childhood peptic ulcer is stressed.

Suicidal age and childhood onychophagia among neurotic veterans.
Investigated the relationship between childhood onychophagia (fingernail biting) and the suicidal and non-suicidal mean age among 60 hospitalized neurotic veterans. The results show no significant mean age difference between suicidal and non-suicidal veterans; neither does the childhood onychophagia variable "focal suicide" significantly lower either the mean age of suicidal veterans or the mean age of non-suicidal veterans.
Suicidal age and childhood onychophagia among psychotic veterans.
The relationship between childhood onychophagia (fingernail biting) and the suicidal and nonsuicidal mean age among 150 hospitalized psychotic veterans was investigated. The results show that the suicidal mean age is significantly younger than the nonsuicidal mean age and that the childhood onychophagia variable "focal suicide" significantly lowers the mean age of suicidal veterans, but does not significantly lower the mean age of nonsuicidal veterans.
Suicidal behavior and childhood onychophagia in hospitalized psychiatric veterans.
This investigation of adult suicidal behavior and childhood onychophagia among hospitalized psychiatric male veterans suggests that for only personality disorders does childhood non-onychophagia show a significant relationship to adult nonsuicidal behavior. Otherwise, this study indicates that the presence or abscence of childhood onychophagia is not a significant suicidal or nonsuicidal factor among these veterans with a psychotic, neurotic, or personality disorder classification.
