Depression amongst outpatients with traumatic brain injury.

The incidence of depression and its association with subject characteristics in outpatients with traumatic brain injury (TBI) were investigated. Logistic regression was estimated with depressed/not-depressed as the dependent variable in 41 outpatients with TBI who filled out the Beck Depression Inventory-II (BDI-II). Twenty-four of 41 subjects (59%) scored in the depressed categories based on BDI-II scores >13. Fourteen (34%) scored in the moderate or severe depression categories (BDI>19). Logistic regression demonstrated a positive relationship amongst depression and age, female gender, mild TBI, and use of antidepressant and stimulant drugs; and a negative relationship between depression and violent aetiology of injury. ANOVA demonstrated that individuals with mild TBI were significantly older than those with moderate or severe TBI, which might account for the association between depression and age. The implications of these results are discussed.

Adrenal insufficiency masquerading as sepsis in a patient with tetraparesis: a case report.

Several endocrine changes have been reported in patients with tetraplegia after spinal cord injury (SCI). These changes should be considered when prescribing medications that influence the endocrine pathways. Megestrol acetate has gained acceptance as a way to promote weight gain in cachectic patients without significant adverse effects. We present a case of a 51-year-old man with C5-C6 tetraparesis who was only 67% of his ideal body weight and was placed on megestrol acetate 5 months before admission for a urologic procedure. Postoperatively, the patient had severe hypotension and tachycardia that was interpreted as a septic or cardiac event. Further workup revealed subnormal levels of 8AM cortisol. An adrenocorticotrophic hormone stimulation test demonstrated results consistent with adrenal suppression. Hydrocortisone supplementation was started, and 6 months later cortisol levels were within normal limits. Cachexia, hypotension, and mild tachycardia are not uncommon in patients with SCI. When severe hypotension and tachycardia are seen in patients with tetraplegia, the diagnosis of adrenal insufficiency should be considered.

Menière's syndrome: an approach to therapy.

There are patients with symptoms similar to those of Menière's disease who do not have Menière's disease and therefore do not respond to conventional medical or conservative surgical management. Some have subtle disorders of carbohydrate and lipid metabolism and inner ear otosclerosis, which are responsible for the production of their symptoms. The response to dietary therapy confirms that glucose tolerance levels which are not diabetic nor hypoglycemic may be sufficiently significant in relation to inner ear function to produce the symptoms like those of Menière's Disease. Management of inner ear otosclerosis with supplemental sodium fluoride, calcium carbonate, and Vitamin D was also effective in controlling the symptoms in some patients.

An illustration of clinical gait laboratory use to improve rehabilitation management.

The purpose of this report is to illustrate the utility of a gait laboratory as a simple, straightforward aid to psychiatric care. The evaluation and management of a patient with spastic paresis and reduced knee flexion in swing (stiff-legged gait), using quantitative gait analysis, are provided. Spastic quadriceps activity during swing was thought to be the cause of reduced knee flexion, based on traditional physiatric history and physical examination. Gait laboratory analysis, including lower extremity kinematic, kinetic and dynamic electromyographic measurements, demonstrated that the quadriceps were not inappropriately active, as had been expected and suggested, instead, that the reduced knee flexion was secondary to dynamic ankle plantar flexor weakness. Modification of an ankle-foot-orthosis and specific exercises to strengthen the ankle plantar flexors were, therefore, prescribed and resulted in kinematic and kinetic improvements at subsequent gait analysis and a subjective feeling by the patient that gait was better. Gait laboratory analysis was useful in determining the optimal rehabilitation plan.

Quantification of attention-related behaviors in individuals with traumatic brain injury. A pilot study.

Clinical disorders of attention are common after traumatic brain injury but objective measures of their nature and severity are lacking. We developed a standardized independent work task to be performed by patients in a controlled, distracting environment. Videotaped records of patient behavior were made and coded in 15-s intervals for on-task behavior, presence of distractors and presence of extraneous motor behavior. Interrater reliability was good to excellent across eleven testing sessions involving four patients. This evaluation system revealed clinically important differences in on-task behavior among the four patients, as well as different levels of distraction in response to external stimuli. It also showed effects of different tasks and repeated sessions. These data indicate that this evaluation system and accompanying coding process are reliable and provide preliminary evidence that they produce clinically valid results.

Protriptyline as an alternative stimulant medication in patients with brain injury: a series of case reports.

The results of a series of eight individual case reports in which protriptyline, an activating tricyclic antidepressant, was used as a 'stimulant' medication are presented. For some patients with head injury, traditional stimulants, such as methylphenidate, or dopaminergic stimulants, such as levodopa-carbidopa, amantadine, or bromocriptine, may be partially or totally ineffective or not tolerated. Protriptyline can be a very effective alternative and, for some patients, may be the most effective stimulant tried. In low to moderate doses, protriptyline should be considered for trials as an activating/stimulant medication in patients with head injury.

Attitudes and practices regarding clinical hypnosis with psychotic patients--a survey: a brief communication.

Attitudes toward and actual use of hypnotherapeutic techniques with psychotic patients were assessed. Results are discussed in light of historical and current attitudes toward the use of hypnosis with psychotics. Respondents were selected from the 1980 membership directory of the Society for Clinical and Experimental Hypnosis (SCEH). 80 respondents completed and returned the survey. Results indicate that the perceived usefulness of hypnosis with psychotics is currently quite high and negative attitudes toward its use quite low. The growth of the use of hypnotherapeutic techniques and the need for further research are discussed.

Lithium carbonate for aggressive behavior or affective instability in ten brain-injured patients.

Lithium carbonate (LiCO3) was used to treat 10 brain-injured patients with severe, unremitting, aggressive, combative, or self destructive behavior or severe affective instability. Five patients had a dramatic response that resulted in significant improvement in their participation in a rehabilitative program. One other patient had a moderate response. A seventh patient improved dramatically, but regressed after 7 wk. Three other patients had neurotoxic side effects that precluded continued use of the medication. Two of them were simultaneously taking neuroleptic agents. These case reports provide further evidence that LiCO3 can be a useful medication in the treatment of aggressive behavior and affective instability after brain injury, but that it has significant potential for neurotoxicity in this population, particularly when used in conjunction with neuroleptic agents.

Carbamazepine replacement of phenytoin, phenobarbital and primidone in a rehabilitation setting: effects on seizure control.

Most patients who receive anticonvulsants after traumatic brain injury are treated with the sedative anticonvulsants phenytoin and/or phenobarbital, or perhaps primidone. However, there is considerable evidence demonstrating that these medications have a deleterious effect on cognitive function. Thus, in a rehabilitation setting, alternatives should be sought. Carbamazepine has been found to be relatively free of such effects, and would be an optimum alternative if seizure control were comparable. We have studied the effects of withdrawing phenytoin, phenobarbital and primidone, and using carbamazepine as the primary anticonvulsant in 27 patients at the Greenery Rehabilitation and Skilled Nursing Center for whom ongoing anticonvulsant treatment was considered to be necessary due to previous seizures or a high risk of the occurrence of seizure. We compared a 3 month baseline period (just prior to carbamazepine introduction or sedative anticonvulsant tapering), to a 3 month post-withdrawal period immediately following sedative anticonvulsant withdrawal, when carbamazepine was the sole anticonvulsant. In 20 out of 21 patients in whom carbamazepine replaced sedative anticonvulsants seizure control was essentially similar or somewhat improved. In only one patient did the substitution with carbamazepine result in a loss of seizure control. Six patients were initially receiving carbamazepine in combination with phenytoin and/or phenobarbital. The removal of phenytoin and phenobarbital, leaving carbamazepine as sole therapy, resulted in improved seizure control in three patients and no change in the other three. In the light of carbamazepine's reportedly less detrimental effects on cognitive function and behaviour in other patient populations, it should perhaps be considered as a first line anticonvulsant, especially for patients in rehabilitation settings.

Serum albumin as a predictor of course and outcome on a rehabilitation service.

To determine the effect of nutritional status on the medical course and rehabilitation outcome of patients on an adult rehabilitation service, serum albumin (SA) and total lymphocyte count (TLC) were prospectively studied on 36 patients. Readings were taken on admission (T-1), at which time a Barthel Index Mobility Goal (BIMG) was assigned, and again 4 to 8 weeks after admission (T-2). A Barthel Index Mobility Score (BIMS) was assigned at discharge. Rehabilitation program restrictions due to medical complications correlated negatively with both the SA level at T1 (r = -.328, p less than 0.05) and at T2 (r = -.523, p less than 0.01). The SA level at T2 correlated positively with the BIMS:BIMG ratio (r = .416, p less than 0.05) at discharge, suggesting that SA levels may predict patient mobility outcome.
