Posttraumatic stress syndromes: Useful or negative heuristics?

The articles in this special issue provide a wide range of challenges to current conceptions, nosology, and assessment procedures for posttraumatic stress disorders. At best, they overcome the negative heuristic posed by these disorders, reopening issues that have preemptively been closed about dissociation, the presumed causal connection between a life threatening event and the symptoms of posttraumatic stress disorders, and the adequacy of checklist assessments of symptoms. They note discontinuities between current thinking about these disorders and the dominant thinking of the past. We make recommendations for more studies that similarly challenge the validity of current conceptions of posttraumatic disorders and dissociation, and the adequacy of checklist assessments of symptoms. With this goal, we note the value of studying ersatz posttraumatic stress response. Finally, we call for greater transparency in this literature with author disclosure of activity as expert witnesses.

The effect of short-term dependency and immobility on skin temperature and colour in the hand.

The effects of short-term dependency and immobility on skin temperature were assessed in two experiments. In the first study, ten volunteers hung their left arm dependent and motionless while using their right hand for light office work. After 30 minutes, the dependent left hands were cooler (mean=0.9 degrees C: 95% CI=0.7-1.1) than the active right hands and exhibited a deeper colour with significantly increased green intensity (P=0.03) as assessed on digital images. In the second study, seven volunteers submerged both their hands in water at 15 degrees C for 15 minutes. The left arm was then left dependent and motionless while the right hand was placed on the table and its fingers were flexed and extended every 10 seconds. The left hands remained cooler than the right and were a median of 3.6 (range 2.9-4.5) degrees C cooler after 60 minutes. These studies demonstrate that skin temperature and colour differences between the hands, which are sometimes used to support the diagnosis of CRPS-1, can be produced and maintained by short-term immobility and dependency of the hand.

An act of homicide and what it brings to mind: a case presentation.

There are many views and studies as to the motive, manner, and victim of homicide, which is one of the severest forms of violence. The case presented here is that of a man who was strangled with a nylon ligature by his prison cellmate who later stabbed his victim's eyes with a piece of wood and a nail and slashed his face. The study is presented with respect to how the murder was committed and how the defendant was evaluated.

Intra-uterine fluid collection in postmenopuasal women with cervical stenosis.

OBJECTIVES: The aim of the study was to assess the clinical significance of intra-uterine fluid collection in postmenopausal women with cervical stenosis with and without vaginal bleeding. METHODS: A group of 82 consecutive postmenopausal women with cervical stenosis and sonographically confirmed intra-uterine fluid collection underwent D&C with or without hysteroscopy. Diagnostic hysteroscopy was performed in all patients with an endometrial thickness (ET) was greater than 8mm, or with irregular endometrium at any degree of ET. The patients were divided and evaluated prospectively into two groups according to the presence or absence of postmenopausal bleeding (PMB). Twenty-six women were with PMB and 56 women were asymptomatic. RESULTS: The groups were similar as far as endometrial thickness and histopathological results were concerned. Atrophic endometrium was found in 69 patients (84%), 23 in the PMB group (89%) and 46 in the other group (82%), proliferative endometrium in 7 (9%) and endometrial polyps were found in 35 patients (43%), 12 in the PMB group (46%) and 23 in the other group (41%). When ET was > or =8 mm, in 93% of the cases an endometrial polyp was found (25 out of 27). No case of endometrial cancer was found. A premalignant condition was diagnosed in one patient with an endometrial polyp in the PMB group. All patients with endometrial thickness of less than 3 mm in ultrasound had atrophic endometrium. The incidence of intrauterine pathology increased with the increasing thickness of endometrium as observed by ultrasound. CONCLUSIONS: The presence of intra-uterine fluid collection in postmenopausal patients with cervical stenosis seems to be a benign condition. Normal endometrium of less than 3mm observed by ultrasound in postmenopausal women without vaginal bleeding does not necessarily need further surgical investigation.

Neuropsychological health in F-111 aircraft maintenance workers.

OBJECTIVE: To contrast subjective and objective measures of neuropsychological health in F-111 aircraft Deseal/Reseal maintenance personnel, against two appropriate comparison groups. METHODS: Exposed and comparison participants completed a postal questionnaire which included a validated memory questionnaire and additional questions relating to possible cognitive symptoms. They also underwent a comprehensive neuropsychological assessment and screening for a past or current disturbance of mood. Multiple linear or logistic regression was conducted for each outcome using exposure group and potential confounders as explanatory variables. RESULTS: There was a strong and consistent excess of self-reported cognitive problems among the exposed group relative to the comparison groups including a 2.8-4.3-fold increase in self-reported symptoms of forgetfulness, loss of concentration and difficulty finding the right word. On detailed neuropsychological testing, the exposed group performed significantly worse than comparisons on tests of psychomotor speed, executive functioning, and new learning/memory. These findings could not be accounted for by disturbances of mood or other potential confounders. CONCLUSIONS: There was a strong and consistent increase in self-reported cognitive problems among the exposed, and small but significant exposure-specific differences on objective tests of cognitive functioning. The findings are consistent with the development of adverse neuropsychiatric changes related to occupational exposure to solvents.

On the meaning of "drug seeking".

The term "drug seeking" is frequently used but poorly defined. By soliciting nurses' comments and suggestions, a survey was developed to identify behaviors that may cause nurses to refer to a patient as drug seeking, to identify what nurses think the term "drug seeking" means, to explore how nurses regard the use of the term "drug seeking" in health care, and to identify differences between general nurses, emergency nurses, and pain management nurses with regard to these items. Behaviors that would cause the majority of all three nurse groups to refer to a patient as drug seeking were as follows: going to different emergency departments to get opioids, telling inconsistent stories about pain or medical history, or asking for a refill because the prescription was lost or stolen. When the term "drug seeking" is used, all three groups of nurses agreed that it was very likely to mean the patient was addicted to opioids, the patient was abusing pain medicine, or the patient was manipulative. One-half or more for each nurse group said they used the term "drug seeking" in talking about patients, but less than 10% said they used it in charting. After completing the survey, approximately one half or more of nurses in each group were less inclined to use the term. The use of stigmatizing terms in clinical practice is addressed with suggestions for alternative approaches to patient behavior related to requesting opioids for pain relief.

Psychiatry and the military: an update.

The United States has historically been concerned about the successful adjustment of its military members returning from war. These concerns are based on the recognition that war-zone exposures may have considerable negative emotional or behavior consequences. As the global war on terror continues, the United States military medical system will be required to address issues at the interface of psychiatry and the law. Despite clinical advances within the theater of war and at tertiary facilities in the United States, some military members will develop chronic and disabling mental illness as a result of traumatic exposure and exacerbated by the demands of the austere and dangerous operational environment. The extent to which violent and aggressive behavior in the aftermath of deployment can be attributed to combat experience remains an area of debate and ongoing investigation. However, experience suggests that a very small subgroup of the hundreds of thousands of war veterans deployed in conjunction with the current conflict in Iraq has already been involved in violent crimes. For this group, military forensic psychiatrists will be called on to make determinations of competency and criminal responsibility and to inform the courts about the potential contributions of war-related distress or disorder to criminal behavior. Though the overwhelming majority of war veterans will not be involved in criminal proceedings, a minority will develop career-ending (and in rare instances, life-ending) disabilities as a result of mental illness. For those who are no longer fit for duty, the military Physical Disability Evaluation System must make determinations of the extent to which future military performance and future civilian social and occupational function have been compromised. For a small yet highly visible minority of returning veterans, questions about the cause, precipitants, and manner of death will necessitate psychological autopsies. This article highlighted recent updates in military forensic psychiatry and the mechanisms through which answers to questions of disability and criminal culpability, and motivation underpinning self-injurious behavior, are determined within the United States military. As the global war on terror progresses, further experience and study of our country's judicial processes, disability system, and the policies and procedures governing psychological autopsies must evolve to meet these increasing demands.

Quartz stones: spurious or iatrogenic?

We describe 2 cases of spurious quartz-containing calculi; the first patient-driven and the second iatrogenic. An iatrogenic etiology can occur after the use of holmium:yttrium-aluminum-garnet laser energy because the fiber tip is composed of quartz. To make the diagnosis of a spurious stone, a high degree of suspicion is essential. A quartz stone should prompt the diagnosis of a factitious disorder in the absence of the appropriate surgical history. Psychological counseling and/or referral to a pain management clinic should be considered in such cases.

The monocular vertical prism dissociation test.

PURPOSE: To determine if the monocular vertical prism dissociation test can differentiate between organic and nonorganic visual loss. DESIGN: A prospective, single-masked observational study. METHODS: Three institutional neuro-ophthalmology practices. Group 1 consisted of 30 normal controls. Group 2 included 30 patients with known organic visual loss. Group 3 contained 35 patients with suspected nonorganic monocular visual loss. Participants were asked to describe what they saw while viewing a single Snellen letter when a 4-prism diopter base-down prism was placed in front of their better eye. Outcome was measured by whether the participant sees one or two letters with the prism in place. RESULTS: Vision-appropriate results were given by all members of Group 1 (two images) and by all members of Group 2 (one image). Two images were seen by 31 of 35 members of Group 3, indicating nonorganic visual loss. The other 4 subjects in Group 3 saw one image; each was subsequently found to have occult pathology. CONCLUSION: The vertical prism test quickly differentiates organic from nonorganic monocular visual acuity loss.

Use of a forced-choice test of tactile discrimination in the evaluation of functional sensory loss: a report of 3 cases.

The loss of sensation is not an uncommon associated finding after injury to the peripheral nerves and the spinal cord. However, the sensory examination is prone to the influence of nonphysiologic factors, and one cannot use it to determine whether functional sensory loss reflects unconscious or intentional symptom production. This distinction has important implications for differential diagnosis and for decision making in the context of workers' compensation claims and personal injury litigation. We present 3 cases of patients with chronic pain and nondermatomal patterns of loss of fine-touch sensation, whose sensory loss was examined by a sensory forced-choice symptom validity test. Their below-chance scores showed intentionally produced sensory symptoms. The use of this methodology in differential diagnosis is discussed.
