Assault characteristics and posttraumatic stress disorder in rape victims.

A diagnosis of posttraumatic stress disorder (PTSD) encompasses several of the symptoms associated with the response to rape. The object of this study was to determine the incidence of PTSD among 51 rape victims and to compare the groups with and without PTSD with respect to the characteristics of the assaults. The results showed that 70% of the victims had PTSD and further suggested that PTSD was likely to be a long-term problem for these women. The results supported the view that psychological treatment approaches to rape victims should take into account the posttraumatic nature of the response. The incidence of rapes by strangers, of physical force being used, of weapons being displayed and of injuries being sustained by the victim were all higher in the group of women who had PTSD. These are all features that can be readily identified in the initial assessment of the rape victim and may help to identify the victims at risk of developing long-term psychological sequelae after rape. Appropriate therapeutic action taken early may influence the prognosis for a significant proportion of rape victims.

Rape--a comparison of stranger and acquaintance assaults.

One of the variables that influences victim trauma in rape attacks is the relationship between assailant and victim (Ellis, 1981). Rapes by strangers have been shown to involve more violence and trauma (Katz and Mazur, 1979). Rapes by acquaintances may involve a betrayal of trust. The study compares 21 rape attacks where the assailant was known to the victim with 30 attacks where the assailant was a stranger. Three main elements of each assault are described: the contextual nature of the rape encounter, the assault characteristics (force, injuries, nature of sexual activity) and the post-rape behaviour. Significant differences were found between the two groups in each of these respects. Contact between rapist and victim took place in a social setting immediately prior to the assault in significantly more of the acquaintance rapes. Significantly more of the stranger rapes involved the display of a weapon. Coercive reciprocation of sexual activity occurred in proportionately more of stranger rapes. The role of verbal aggression was more prominent in acquaintance rapes. Significantly more of the acquaintance rapists (95% as opposed to 17%) interacted with the victim after the overtly sexual part of the attack. Two types of behaviour were displayed in almost equal proportions. Conciliatory/non-threatening behaviour consistent with a distorted affirmation of a person-orientated relationship with the victim was displayed by 43% of these assailants; 48% displayed threatening behaviour. We believe that stranger and acquaintance rapes can be clearly differentiated in terms of the behavioural dimensions of the assault. An understanding of such differences has implications for professionals involved in the assessment and treatment of sexual offenders and their victims.

The management of diabetes in general practice.

Over a period of 3 months 32 general practitioners in the Waikato kept copies of all consultations with patients with noninsulin-dependent diabetes mellitus. Of 229 patients with diabetes known to the practices 189 were seen on a total of 438 occasions. Mean fructosamine level was 2.93 mmol/L. Each consultation was analysed as to history obtained, examinations performed, investigations ordered and referrals made. Overall care was satisfactory except for the low incidence of checking for early signs of peripheral vascular disease or diabetic neuropathy affecting the feet and for diabetic nephropathy.

[The problem of animal models for psychiatric conditions, as illustrated by the immobilization reaction (catalepsy) in the rat (author's transl)].

According to Venables the span of psychotic processes extends from a low level of arousal with an increased reactivity toward sensory stimuli to a high level of arousal with a reduced reactivity toward sensory stimuli. The level of arousal and the degree of reactivity, or breadth of attention, are apparently controlled by a regulatory mechanism which increases the threshold for sensory input in threatening situations. Any factor producing an electroencephalographic arousal reaction leads to a narrowing of attention. Underestimation of the size of a given object is an expression of such a reduction in the span of attention. Various authors have found a reduction in size-constancy in schizophrenics, in particular in patients exhibiting a merkedly reduced contact with their environment. A model is described in which a strong sensory stimulus induces a state of immobilization in rats treated with a low dose of morphine. Electroencephalographic recordings show that the initial state of arousal induced by peripheral stimulation is replaced by high-amplitude slow-waves and spindles as the state of immobilization develops. The current results suggest that the sensory stimulation leads to excitation of the ascending reticular formation and via the Centrum medianum and the Nucleus centralis, to activation of the striatal system, resulting in catalepsy. It would thus appear that the reticular formation and the striatum alternate in excercising a control function over the state of arousal. This would be a logical way of limiting over-reaction, which can be demonstrated most simply on the motoric response. It seems justified, therefore, to assume a relationship between catatonic stupor and the immobilization induced by stimulation. This concept is supported by the observation that of all the compounds investigated only clozapine is capable of inhibiting the immobilization in the rat model. Clozapine is a powerful antipsychotic agent with a pronounced inhibitory effect both on the reticular arousal reaction and on the schizophrenic catatonia.
