Objective: To investigate the influence of relationships on psychosocial status in patients with Stage III and IV brain tumours., Patients and Methods: Thirty-three outpatients at a university medical centre were referred to the study by their treating physician prior to the initiation of aggressive chemotherapy. All subjects underwent a comprehensive psychosocial assessment., Results: Depressive and anxious complaints were common, but not related to gender. Single/divorced status suggested greater vulnerability to anxiety as 88% of singles and only 48% of patients with partners reported clinical levels of anxiety. Single patients' anxiety was related to inactivity (r = 0.78, p < 0.05) and fears of financial difficulties (r = 0.72, p < 0.05). State and trait anxiety related differently to married patients' complaints. Married patients more frequently reported clinical levels of depressive symptoms (44% partnered vs 28% singles). Depression among married patients was predicted by problems with sex, finances, marital difficulties, and inactivity [R2 = 0.803; F = 20.420, df(4,20), p < 0.0001)]. Problems with relationships were disassociated from problems with sex. Married patients' problematic relationships were predicted by overprotection, inactivity, concerns of bodily deterioration, depression, and anxiety [R2 = 0.775, F = 13.060, df(5, 19) < 0.0001]., Conclusions: Married neuro-oncology patients may experience depressive symptoms arising from the marriage, but appear to be buffered from anxiety when compared with single/divorced patients. The prevalence of anxiety among single patients suggests modifications of interventions by relationship status.

Background: The aim of this study was to determine the safety and efficacy of intraarterial chemotherapy with osmotic opening of the blood-brain barrier (BBB) for the treatment of malignant brain tumors when administered across multiple centers., Methods: Patients with primary central nervous system lymphoma (PCNSL), primitive neuroectodermal tumor (PNET), germ cell tumor, cancer metastasis to the brain, or low or high grade glioma were eligible. Prior to entry, magnetic resonance imaging or computed tomography brain scan, medical history, neurologic status, and Karnofsky performance status were reviewed at the coordinating center. Standardized anesthesia and intraarterial catheterization guidelines were followed by a multidisciplinary team at each center. Between March 1994 and November 1997, 5 universities treated 221 adult patients with intraarterial chemotherapy with or without osmotic opening of the BBB (2464 procedures)., Results: Of evaluable patients with PCNSL, 40 of 53 (75%) achieved complete response (CR). All evaluable patients with PNET (n = 17), metastatic disease (n = 12), or germ cell tumor (n = 4) achieved stable disease (SD) or better. Of 57 evaluable patients with glioblastoma multiforme, 45 (79%) achieved SD or better. Asymptomatic subintimal tear occurred in 11 of 221 patients (5%), pulmonary embolism in 6 of 221 (2.7%), and renal toxicity in 4 of 221 (1.8%). One patient with extensive glioma expired within 48 hours after treatment., Conclusions: Using standard guidelines and protocols, intraarterial chemotherapy with or without osmotic opening of the BBB is feasible across multiple centers with a low incidence of catheter-related complications. In patients with chemotherapy-sensitive tumors, such as PCNSL, PNET, germ cell tumor, and cancer metastasis to the central nervous system, enhanced delivery results in a high degree of tumor response, with an efficacy profile that is reproducible across multiple centers., (Copyright 2000 American Cancer Society.)

Prospective, longitudinal follow-up of academic status following pediatric traumatic brain injury (TBI) identified that patients with severe TBI (n = 33) obtained significantly lower reading recognition, spelling, and arithmetic scores than those with mild to moderate TBI (n = 28). Independent of injury severity, adolescents scored lower than children on computational arithmetic and reading comprehension subtests. Although all achievement scores increased significantly from the baseline evaluation to 6 months after the injury, no further change was noted from 6 months to 2 years. Despite average achievement test scores by 2 years after TBI, 79% of the severely injured patients had either failed a grade or received special educational assistance. Traditional achievement tests may be insensitive to posttraumatic academic deficits.

Objective: The purpose of the study was to demonstrate the utility of the middle fossa transpetrosal approach with anterior petrosectomy for difficult-to-access petroclival and pontine lesions., Study Design: Retrospective case review in academic tertiary referral center., Methods: Patients for inclusion had pontine and prepontine lesions of the petroclival region. Middle fossa transpetrosal approach with anterior petrosectomy with excision or biopsy of the lesion was performed. The main outcome measure was postoperative neurologic status including motor and cranial nerve function., Results: No patient experienced neuromuscular compromise or cranial nerve deficits as a direct result of the surgical procedure. Complications consisted of a subdural temporal lobe hemorrhage and one case of cerebrospinal fluid rhinorrhea., Conclusions: The middle fossa transpetrosal approach with anterior petrosectomy was utilized for five patients with petroclival or pontine tumors. In this small series, it served well to spare cranial nerves and allowed avoidance of serious vascular injury. To our knowledge, this is the first reported use of this procedure for pontine venous angiomas.

Objective: To investigate the relevance of the Symptom Checklist 90-R Obsessive-Compulsive subscale to cognition in individuals with brain tumor., Design: A prospective study of patients assessed with a neuropsychological test battery., Setting: A university medical center., Patients: Nineteen adults with biopsy-confirmed diagnoses of malignant brain tumors were assessed prior to aggressive chemotherapy., Main Outcome Measures: Included in the assessment were the Mattis Dementia Rating Scale, California Verbal Learning Test, Trail Making Test B, Symptom Checklist 90-R, Mood Assessment Scale, Beck Anxiety Inventory, and Chronic Illness Problem Inventory., Results: The SCL 90-R Obsessive-Compulsive subscale was not related to objective measures of attention, verbal memory, or age. It was related significantly to symptoms of depression (r = .81, P < .005), anxiety (r = .66, P < .005), and subjective complaints of memory problems (r = .75, P < .005). Multivariate analyses indicated that reported symptoms of depression contributed 66% of the variance in predicting SCL 90-R Obsessive-Compulsive Scores, whereas symptoms of anxiety contributed an additional 6% (P < .0001)., Conclusions: Our data suggest that the SCL 90-R is best viewed as an indicator of unidimensional emotional distress and somatic effects of structural brain injury.

Patients with brain tumours often report distress. Interpretive problems ensue when measures normed on healthy persons are utilized to quantify distress. This study investigated potentially spurious elevations on the Hopkins Symptom Checklist 90 Revised (SCL 90-R). Responses of 17 patients were obtained prior to aggressive chemotherapy. Traditional interpretation indicated that 47% of the patients endorsed clinical levels of somatization, 53% obsessive-compulsive and 59% psychotic disorders. Elevations were attributable to common consequences of brain tumours, medication and the emotional reaction to prognosis. Conventional interpretation would lead to inappropriate classifications. The majority of SCL 90-R item endorsements were significantly different than those of the norm group. Appropriate interpretation of scores is discussed.

Neuropsychological outcome was evaluated in a prospective, longitudinal follow-up study of children age 4 months to 7 years at injury with either mild-to-moderate (N = 35) or severe (N = 44) traumatic brain injury (TBI). Age-appropriate tests were administered at baseline, 6 months, 12 months, and 24 months after the injury. Performance was compared on (1) Composite IQ and motor, (2) Receptive and expressive language, and (3) Verbal and Perceptual-Performance IQ scores. In comparison to mild-to-moderate TBI, severe TBI in infants and preschoolers produced deficits in all areas. Interactions between task and severity of injury were obtained. Motor scores were lower than IQ scores, particularly after severe TBI. Both receptive and expressive scores were reduced following severe TBI. Expressive language scores were lower than receptive language scores for children sustaining mild-to-moderate TBI. While severe TBI lowered both Verbal and Perceptual-Performance IQ scores, Verbal IQ scores were significantly lower than Perceptual-Performance IQ scores after mild-to-moderate TBI. Mild injuries may produce subtle linguistic changes adversely impacting estimates of Verbal IQ and expressive language. Within the limited age range evaluated within this study, age at injury was unrelated to test scores: The impact of TBI was comparable in children ages 4 to 41 months versus 42 to 72 months at the time of injury. All neuropsychological scores improved significantly from baseline to the 6-month follow-up. However, no further change in scores was observed from 6 to 24 months after the injury. The persistent deficits and lack of catch-up over time suggest a reduction in the rate of acquisition of new skills after severe TBI. Methodological issues in longitudinal studies of young children were discussed.

Does increased intracranial pressure in patients with pseudotumour cerebri (PTC) result in cognitive impairments? The results of previous investigations have not clarified this question. It may be that there is a subgroup within those diagnosed with PTC that does experience cognitive decline with increased intracranial pressure. However, elevated intracranial pressure, headache, and emotional distress also can contribute to reduced cognitive performance and increased self-monitoring. As a result of the lack of clarity regarding the impact of PTC on cognition clinicians are left with no empirically derived practice guidelines. A case study demonstrates subjective complaints of concentration and memory deficits in a depressed patient with PTC whose neuropsychological stores (except Seashore Rhythm Test) were in the normal range.

Little is known regarding affect and the quality of life of elderly persons with malignant brain tumours. More elderly patients are currently being diagnosed with primary malignant CNS tumours and current, aggressive treatment has extended median life expectancy. This case study indicated significant levels of clinical depression and anxiety may be experienced. Additionally, trait anxiety was found to increase with tumour progression. The patient's concern regarding loss of conjugal closeness and social inactivity was identified for the first time in persons with malignant brain tumours. Being progressively less active physically, and more isolated emotionally, this patient used her relatively good general intellectual abilities to worry about her situation. At the present time integration into the community and distress over her ability to be assertive decreased. Practical barriers to the delivery of psychological services were encountered and are likely to have been under appreciated.

Access to the central venous circulation is often necessary in patients who have elevated intracranial pressure. It has been suggested that a disadvantage of the internal jugular vein approach to the central circulation may be an elevated intracranial pressure. The purpose of this prospective study was to evaluate the effect of right internal jugular vein cannulation on intracranial pressure in patients who are at risk of intracerebral hypertension. Eleven adult patients studied in the intensive care unit were evaluated. The population included those patients who were admitted to the neurosurgical intensive care unit requiring intracranial pressure monitoring and central venous access. With the intracranial pressure monitor in place, patients were put in supine and 30 degrees head-up positions while intracranial pressure was recorded. The Queckenstedt maneuver was performed on all patients. A central venous line was then placed in the right internal jugular vein, and intracranial pressure was recorded. The Queckenstedt maneuver was again performed in the study population, and intracranial pressure measurements were recorded for the right, left, and bilateral compression of the internal jugular vein. The results of the intracranial pressure measurements before and after placement of the central venous line were statistically analyzed using single-factor analysis of variance over time. The mean Glasgow coma and Apache II scores for the study groups were 8 +/- 4 and 15 +/- 6, respectively. There were no significant differences in heart rate; cerebral perfusion pressure; or systolic, mean, or diastolic pressures throughout the study period. There was no statistical difference found between the intracranial pressures at any time point throughout the study. Furthermore, no difference was found in percentage change from baseline intracranial pressure data throughout the study period. Our results suggest that cannulation of the right internal jugular vein is a safe approach to the central circulation in patients at risk of intracranial hypertension. A description of the possible accommodating mechanisms are outlined.

Between 1986 and 1990, 37 of 72 patients undergoing decompressive lumbar laminectomy with medial facetectomy for lumbar stenosis at The Ohio State University were seen in follow-up at a mean of 31 months (range, 14-63 months) after their laminectomy and were evaluated by questionnaire, detailed neurologic examination, and static and dynamic lumbar radiographs. Thirteen patients who had undergone fusion or who had extenuating medical circumstances were excluded, leaving 24 patients for whom laminectomy was the sole treatment for lumbar stenosis. Postoperatively, normal walking improved from 4 to 45% of patients, sensory deficits decreased from 63 to 25%, and ability to perform most or all desired activities increased from 25 to 70%. Urinary function was unchanged. Thirteen patients (54%) showed radiographic signs of instability. All patients who were declared radiographically stable could walk without a prosthetic aid or normally; 62% of the unstable patients required aid for walking. All of the patients with a poor ambulatory outcome were radiographically unstable. Compared with stable patients, unstable patients had a significant (p < 0.01) decrease in their ambulatory ability. There was a clear correlation between the degree of listhesis and postoperative ambulatory status (p < 0.01). The unstable patients with a poor ambulatory outcome followed one of three clinical courses: improvement with later deterioration, improvement with a plateau at a poor functional level, or failure to improve from a poor functional level. In conclusion, (a) although instability did not necessarily preclude a good outcome, a poor ambulatory outcome was always associated with instability; (b) laminectomy can effectively ameliorate the symptoms of lumbar stenosis; however, there is a subset of patients in whom laminectomy is associated with instability and a poor clinical course.

Examined the relationship of hydrocephalus and behavioral adjustment in three groups of 5- to 7-year-old children (N = 84) with a history of early hydrocephalus (spina bifida, prematurity, aqueductal stenosis) and three non-hydrocephalic comparison groups (spina bifida, prematurity, normals). Results revealed no significant group differences on measures of behavioral adjustment and a variety of family and sociodemographic variables. Children with hydrocephalus were more likely to meet criteria for behavior problems, obtained lower scores on measures of adaptive behavior, and perceived themselves as less physically competent. Categorical modeling analyses showed that hydrocephalus and its treatment, gender, family variables, and motor skills were related to the presence of behavior problems.

Neurobehavioral outcome after craniocerebral gunshot wounds was evaluated in a prospective, 3-year, longitudinal follow-up of a consecutive case series of 13 children and adolescents. The younger group was composed of seven children, ages 1.5 to 4 years, and the older group contained six children, ages 5 to 14. Outcome measures included the Glasgow Outcome Scale and neuropsychological assessment of intelligence, language, motor, memory, attention, academic achievement, and adaptive behavior. Glasgow Outcome Scale scores at baseline indicated moderate and severe disabilities in 69 and 23%, respectively. At the 3-year follow-up, 85% had moderate disabilities but only 8% were severely disabled. Significant and persistent neurobehavioral deficits varied with developmental level at the time of cerebral insult. Intellectual functioning was clearly more impaired in children younger than 5 years of age at the time of injury than in older children. Cognitive and motor factors were most closely related to deficits in the younger group. Disability in older children and adolescents was associated with impaired attention, adaptive behavior, and behavioral disturbance. Disabilities appear to be at least as severe in our sample after cerebral gunshot wounds as in our studies of severe pediatric closed-head injury. At the time of follow-up, younger children sustaining gunshot wounds had slightly lower intelligence quotient scores and similar receptive language, expressive language, and gross motor scores compared with children with severe closed-head injury. The older gunshot wound patients were significantly more impaired than patients with severe closed-head injuries on measures of adaptive behavior and attention.(ABSTRACT TRUNCATED AT 250 WORDS)

The influence of severity of closed head injury and age on attentional functioning was prospectively investigated in 36 children (age range, 7 to 16 years) 6 months after injury. Children were placed into mild, moderate, and severe injury groups using established neurologic criteria. Each child received the Wechsler Intelligence Scale for Children-Revised Digit Span subtest and a continuous performance test. Children with severe closed head injury demonstrated significantly poorer continuous performance test scores than mildly or moderately injured children. Injury severity had no effect on Digit Span scores. Younger children exhibited more pronounced impairment on the continuous performance test relative to uninjured age peers. These results extend the persistence of attentional impairments beyond those of previous reports. Closed head injury is not associated with preferential sparing of sustained attention in younger children 6 months after injury. Brain injury earlier in life may result in delayed vulnerability of information processing skills.

Although children with hydrocephalus frequently show poor development of nonverbal cognitive skills relative to verbal skills, little is known about the neuropathologic correlates of these discrepancies. In this study, cerebral white-matter structures and lateral ventricles were measured from the magnetic resonance images of age-matched children with meningomyelocele, meningocele, and aqueductal stenosis and normal subjects. The volume of each lateral ventricle and the cross-sectional area of the corpus callosum and internal capsules were correlated with concurrent measures of verbal and nonverbal cognitive skills. The corpus callosum in the meningomyelocele and aqueductal stenosis groups was smaller. The lateral ventricles were larger, and the internal capsules were smaller, in all patient groups than in normal subjects. There were no differences in the size of the centra semiovale. Although verbal and nonverbal measures correlated positively with the size of the corpus callosum, the correlation was higher for nonverbal measures. Nonverbal measures correlated with the right, but not the left, lateral ventricle and with the area of the right and left internal capsules. Verbal measures correlated with the left, but not right, lateral ventricle and with the left, but not right, internal capsule. These results show a relationship between the corpus callosum and cognitive skills that is also influenced by hydrocephalus-related changes in the lateral ventricles and other cerebral white-matter tracts.

This study evaluated a large sample (N = 90) of 5- to 7-year-old children with hydrocephalus caused by aqueductal stenosis or prematurity-intraventricular hemorrhage or associated with spina bifida. Comparison groups of normal controls, children with spina bifida and no shunt, and premature children with no hydrocephalus were also evaluated. Comparison of skill discrepancies at two occasions separated by 1 year revealed that hydrocephalic children, as a group, showed poorer nonverbal than verbal skills on measures from the McCarthy Scales of Children's Abilities, the WISC-R, and composites of neuropsychological skills. No discrepancies in verbal-nonverbal memory were found nor were any discrepancies attributable to etiology or motor demands of the tasks. Consistent with current hypotheses concerning the role of the cerebral white matter in cognitive development, these results show that hydrocephalic children in this age range generally have poorer development of nonverbal cognitive skills relative to their language development.

Seven cases of spontaneous epidural abscess are reviewed. Three patients had posterior abscesses and no evidence of vertebral body osteomyelitis. These patients had excellent outcomes with laminectomies and antibiotics. Because of significant vertebral destruction, two patients with vertebral osteomyelitis required posterior fixation after laminectomy. Two other patients with vertebral osteomyelitis had complete destruction of the vertebral body and required anterior decompression and fusion in addition to posterior fixation. In the four patients with vertebral osteomyelitis, morbidity was high, reflecting their age and significant medical problems. This review supports the contention that medically stable patients with posterior epidural abscesses can be treated with laminectomy and antibiotics with little risk of progressive instability. The proper surgical treatment of anterior epidural abscesses secondary to osteomyelitis requires knowledge about the amount of destruction of the supporting columns, the amount of neural compression secondary to the purulence, and the patient's general medical condition.

This report describes a rare complication after the resection of a tumor of the posterior fossa, the "one-and-a-half" syndrome. The one-and-a-half syndrome is a disturbance of horizontal eye movements in which patients have lateral gaze palsy in one direction and internuclear ophthalmoplegia in the other direction. The patient was a 54-year-old woman who developed headaches, diplopia, and blurred vision over 6 months. Computed tomographic scans and magnetic resonance imaging demonstrated an enhancing, mixed density, midline mass of the cerebellum. After a resection of the mass, an anaplastic astrocytoma, the patient complained of more severe diplopia and facial weakness. An examination disclosed a left one-and-a-half syndrome, left peripheral facial paralysis, dysarthria, dysphagia, mild left hemiparesis, dysmetria of the left upper limb, and truncal ataxia. The brain stem showed no abnormalities on postoperative computed tomographic scans. After 4 months of follow-up, the one-and-a-half syndrome had not improved, even though other signs had improved or resolved. This syndrome is caused by damage to structures within the pontine tegmentum: the medial longitudinal fasciculus, the ipsilateral paramedian pontine reticular formation, or the ipsilateral abducens nucleus. Multiple sclerosis and brain stem infarction are the most common causes of the one-and-a-half syndrome. Less frequently, it is caused by primary and metastatic tumors of the brain stem and cerebellum. Rarely, the one-and-a-half syndrome can develop postoperatively after the removal of tumors of the posterior fossa. The mechanism of pontine tegmental injury remains unknown.

A new index of cerebral hemodynamics, cerebral hemodynamic reserve (CHR), was evaluated in 12 comatose adults with severe, acute, traumatic, diffuse swelling of the brain, who underwent continuous monitoring with a fiberoptic catheter of the saturation difference in arteriojugular oxyhemoglobin. CHR was assessed as the ratio of changes in global cerebral oxygen extraction to changes in cerebral perfusion pressure (CPP) as a result of spontaneous increases in intracranial pressure (ICP). During the course of hyperventilation (Pco2 in the range of 20 mm Hg) for ICP control below 20 mm Hg, 34 observations were made over the initial 48 hours postinjury. Despite normal CPP, in 25 of the observations (73.5%), ICP elevations to the range of 20 mm Hg were associated with compromised CHR, as evidenced by decreases in jugular oxygenation directly attributed to the ICP increases. In the remaining nine observations (26.5%), CHR was preserved, as evidenced by no changes or increases in jugular oxygenation when ICP increased. The CHR improved on the second day, suggesting an improved tolerance of the cerebral hemodynamics to ICP increases. Before the ICP elevations, in most of the observations, the global cerebral blood flow was estimated as being optimally decreased (by hypocapnia), in relation to cerebral oxygen consumption. This was reflected by the occurrence of baseline normalized cerebral oxygen extraction. It is concluded that in this group of patients, under circumstances of profound hyperventilation, ICP elevations within the normal CPP range may result in decreased cerebral oxygenation, even when the normal CPP would imply otherwise. It is suggested that CHR assessment may provide information regarding the status of intracranial "tightness," insofar as cerebral circulation and oxygenation are concerned.

The authors present a case of transient left hemispatial inattention following traumatic brain injury in a three-year-old child. Computed tomographic scan revealed a small right frontal and a right temporo-parietal contusion. Stimuli were developed to quantify the response difference between hemifields in this pre-literate child. Hemispatial inattention showed resolution at 19 days post-trauma and had completely resolved six months later. These findings suggest that right hemisphere systems subserve visually guided attention before six years of age.

The neuropsychological performance of three groups of preschool children was evaluated: (a) one with hydrocephalus associated with myelomeningocele; (b) one with hydrocephalus associated with intraventricular hemorrhage and very low birth weight; and (c) a nonhydrocephalic normal comparison group. Multivariate profile analysis revealed lower levels of performance on measures of verbal and nonverbal cognitive skills for both groups of hydrocephalic children relative to normals. Comparison of group profiles on tasks requiring figure copying as opposed to figure matching and analysis of specific gross and fine motor skills revealed that both hydrocephalic groups had impaired visual-motor integration in the presence of average visual perceptual matching. In addition, different patterns of motor skill deficits were found for each hydrocephalic group. The results of this study suggest that decreased visual-motor integration and etiology-specific motor deficits are major sequelae of these forms of hydrocephalus in the preschool years.

The Children's Orientation and Amnesia Test (COAT) was developed to assess cognition serially during the early stage of recovery from traumatic brain injury in children and adolescents. The norms for the COAT, which is composed of 16 items evaluating general orientation, temporal orientation, and memory, were defined from data obtained from 146 children aged 3 to 15 years. In 37 patients with head injuries, the duration of posttraumatic amnesia, as indicated by the number of days COAT scores were in the impaired range, was significantly related to both verbal and nonverbal memory at the baseline and 6 and 12 months after injury. COAT scores were a better predictor of verbal and nonverbal memory performance than the Glasgow Coma Scale score at 6 and 12 months after the injury. This study shows that the COAT has adequate reliability and validity as a measure of the duration of posttraumatic amnesia in children and adolescents.

Global cerebral oxygenation, perfusion pressure, and expired pCO2 were continuously monitored in 10 adults with acute severe closed head trauma. Cerebral oxygenation was monitored by fiberoptic catheter oximetry, which allowed simultaneous measurements of arterial and jugular bulb oxyhemoglobin saturation. Intracranial pressure levels over 20 mm Hg were recorded several times in all patients, in spite of sedation, muscle paralysis, and profound hyperventilation. Intracranial hypertension was frequently associated with oligemic cerebral hypoxia, identified as abnormally low jugular oxygen saturation in the presence of normal arterial oxygenation. Intracranial hypertension was then managed with intravenous administration of mannitol boluses, which yielded simultaneous decreases in intracranial pressure and increases in cerebral oxygenation to highly statistically significant levels. Monitoring cerebral oxygenation was clinically useful because it allowed identification of impaired cerebral oxygenation even when cerebral perfusion pressure was normal. It is therefore proposed as a new monitoring technique, to supplement conventional monitoring of cerebral perfusion pressure.

During the years 1985-1987, 45 children were hospitalized at our institution for gunshot wounds (GSWs). Twelve suffered GSWs to the brain and five of these survived to be followed by the multidisciplinary team. The purpose of this article is to discuss the neuropsychological outcome of three children who sustained GSWs to the brain during this time period. At our institution, children return for regular follow-up appointments with the neurosurgeon, neuroscience clinical nurse specialist and neuropsychologist. The neurosurgeon conducts the neurological examination, and the nurse performs a developmental assessment and evaluates teaching and follow-up needs. During each appointment, the neuropsychologist administers a battery of tests to determine the effects of GSW on intelligence, language, spatial motor skills, academic achievement and adaptive behavior. Case reports are provided to illustrate the results, with nursing implications and future research in the area of outcome of GSW in children discussed.

This study provides a longitudinal follow-up of the behavioral adjustment of 45 children with mild, moderate, and severe closed head injuries. Two measures of behavioral adjustment, the Child Behavior Checklist (CBCL) and the Vineland Adaptive Behavior Scales (VABS), were obtained from a parent at the time of injury and at 6 and 12 months postinjury. The severely injured children obtained significantly poorer VABS scores than children with mild and moderate injuries over the year-long follow-up. In addition, on the CBCL, severely injured children had more school problems and engaged in fewer social activities than mild and moderately injured children. These results show that severe head injury in children was associated with declines in adaptive functioning, whereas scores for children with mild and moderate injuries did not differ, nor did they deviate from average levels at any follow-up interval.

Thirty-three children ranging in age from 8 months to 15 years were treated for gunshot wounds to the brain. Half of the children were less than 10 years old. Fifty-eight percent died. Mortality was influenced by the trajectory of the bullet, intent to commit suicide, and the neurological status immediately after injury. The age and sex of the child and the caliber of the bullet did not influence survival. Three-fourths of the deaths occurred within 24 hours of injury, suggesting these patients had a mortal wound from the onset. Eleven of the children were attempting suicide, 9 of whom died; 13 were playing with a gun, 5 of whom died; 2 were shot as innocent bystanders to crimes in progress; 1 was shot while involved in a criminal act; 1 was shot in a hunting accident; and in 2 who died within minutes of arrival, the circumstances of the shooting were not documented. Of the survivors, none was left vegetative after 6 months, 3 had severe disabilities, 9 were moderately disabled, and 2 had a good outcome. The mortality rate is strikingly similar to that of adults with similar injuries; however, the morbidity appears to be less. On the other hand, with simple preventative measures, virtually each injury would have been avoided.

This study includes 124 patients with closed head injuries and with Glasgow Coma Scale (GCS) scores of less than or equal to 8, who were admitted over a 7 1/2-month period. The time at which death occurred after injury was bimodal: deaths occurred either within 48 hours or after 7 days or longer after injury. Neurological deterioration, however, occurred with equal frequency on Days 2 to 7 after injury. Patients who survived the first 48 hours and then suffered neurological deterioration did not differ from the total population in age, sex, GCS scores on admission, or pupillary reactivity, but had a much higher incidence of intracranial hematomas of all types. Deterioration occurred three times more frequently in those with hematomas than in those with diffuse brain injury. Patients who deteriorated were rarely among the 35% of those who rapidly improved in the first 48 hours (4 points or more on the GCS). Computerized tomography (CT) scans of those deteriorating (24 patients) could be divided into four categories: 1) those without new mass effect (eight cases); 2) those with new or increased hemispheric edema (six cases); 3) those with generalized edema (two cases); and 4) those with focal or lobar areas of new edema or hemorrhage (eight cases). Of the patients in coma who deteriorated, 19% had large, delayed intracerebral hematomas. In 11 of 16 cases deteriorating with new mass effect, prior compression by overlying extracerebral hematoma, disruption of brain by intracerebral hematoma, or preexisting hemispheric edema preceded the brain swelling that caused deterioration. Areas of disruption or compression on CT scan typically developed decreased attenuation 2 to 7 days after injury, but did not cause deterioration unless new mass effect accompanied the lucency appearing on CT scan. A mortality rate of 29% was achieved for the 124 cases, which were managed with early evacuation of hematomas and control of intracranial pressure. Certain methods are suggested for evaluating therapy and for comparing clinical series.

Five children with intraventricular shunts developed ventriculitis due to organisms resistant to multiple antimicrobial agents but sensitive to gentamicin sulfate. No gentamicin was detected in ventricular CSF of four patients at a time when gentamicin was being administered only intravenously. The intraventricular administration of 1 mg of gentamicin resulted in ventricular CSF concentrations greater than 20 microgram/ml one hour and 5 to 14 microgram/ml 36 hours after administration. Patients were treated with intraventricularly given gentamicin for an average of 16 days, with no apparent complications or relapses during the 12- to 24-month follow-up period. Intraventricularly administered gentamicin sulfate (1 mg every 24 to 36 hours) in conjunction with complete shunt removal was an effective means of therapy of ventriculitis caused by bacteria resistant to antibiotics that readily penetrate the blood-brain barrier.

Ectrodactyly (lobster claw deformity), ectodermal dysplasia and clefting of the lip or palate, the EEC syndrome, is a rare genetic disorder involving both mesodermal and ectodermal derivatives. Cerebral arterial dolichoectasia, a pathological dilatation and elongation of intracranial vessels, was found in a patient with the EEC syndrome. Her hypertensive cardiovascular disease, mild dementia and trigeminal neuralgia were all related to her dolichoectasia. Although the association of dolichoectasia has not been previously observed with the EEC syndrome, it may be more frequent than currently recognized. Cerebral arterial dolichoectasia and its attendant sequelae could account for some of the unexplained abnormalities described in other case reports of patients with the EEC syndrome.

Two premature infants developed enlarging symptomatic hemispheric cysts secondary to intraparenchymal hemorrhages. Computed tomographic scans obtained after metrizamide was injected into the cysts demonstrated that they were isolated from the ventricular system. The cysts were treated by biopsy of the common cyst-ventricular wall through a ventriculoscope. Both patients have been followed for over 1 year. Repeat scans have demonstrated resolution of the cysts, a return to midline of the ventricular system, and an increase in the volume of cerebral tissue. The original abnormal neurological signs have disappeared, and the developmental progress has been excellent.

A 3 mm pellet, shot into the neck of a 13 year old boy, migrated into the common carotid artery and lodged in the infraclinoid internal carotid artery. The case illustrates an unusual intravascular migration of a foreign body. The benign clinical course, radiological evaluation, and rationale for expectant management of such low velocity missle injuries is discussed.

Progressive hydrocephalus in the preterm infant requires judicious management. Fortunately, in some infants, short-term treatment may obviate the need for shunting procedures. This case illustrates the successful control of progressive hydrocephalus in a preterm infant managed by acetazolamide, a carbonic anhydrase inhibitor. The drug was discontinued transiently early in the course of treatment. This patient's clinical course, change in head circumference, and cerebral ultrasound provide evidence of the benefit of this drug regimen in treating hydrocephalus.

A patient with severe closed head injury and tension subcutaneous emphysema developed intracranial hypertension unresponsive to conventional treatment. Subcutaneous air drainage controlled the intracranial pressure. The subcutaneous pressure was directly correlated with intracranial pressure.

Magnetic resonance imaging (MRI) was performed in a series of 21 children and adolescents who had been hospitalized after sustaining closed head injuries of varying severity at least 6 months previously. Areas of high intensity in the parenchyma were present in 8 of the 11 severely injured patients, whereas MRI findings were normal in all 10 patients with mild-to-moderate head injuries. Lesions involving the subcortical white matter were confined to severely injured patients whose clinical features were compatible with diffuse axonal injury. Neuropsychological assessment disclosed deficits primarily in the severely injured patients; these deficits were significantly associated with persistent lesions visualized by MRI. Serial MRI and neurobehavioral assessment following early injury may be useful in documenting cognitive impairment in relation to structural alterations of the young brain.

Intracranial penetration during attempted nasogastric intubation is a rare, usually lethal, but avoidable complication. Such incidents are associated with facial and basilar skull fractures, acute neurologic deterioration, and litigation. We report two such incidents and the successful surgical procedure which utilized craniotomies positioned such that the nasogastric tubing could be removed in small, straight segments. The tubing in each case was removed without increasing the neurologic deficit, and the patients made an acceptable recovery considering their premorbid status.

Examined cognitive and motor performance during the subacute stage of recovery and 8 months postinjury in 21 infants and preschoolers who sustained a closed head injury (CHI). Children sustaining severe CHI, who exhibited impaired consciousness for at least 1 day, were impaired on measures of intelligence, motor, expressive language, and receptive language functions on the baseline and follow-up evaluations relative to children with mild-moderate injuries. Irrespective of injury severity, motor and expressive language functions were the most vulnerable to the effects of CHI. Results are discussed in terms of the rate of development of cognitive functions.

Serum levels of creatine kinase (CK) and its myocardial isoenzyme (CK-MB) were measured and serial ECG recorded in 24 male and 6 female patients with severe head trauma. All patients were comatose, but no patient sustained a spinal or chest injury. Total CK activity was elevated in at least one sample in each patient. Elevated CK-MB activity was found in 28 patients. The serial CK-MB data did not follow the same pattern as that of patients suffering from myocardial infarctions. The mean CK-MB remained elevated for at least 3 days after injury, although individual patterns were variable. ECG abnormalities included prolonged corrected QT interval (QTc) in 90% and a variety of nonspecific ST segment and T wave changes in 53%. These ECG findings are consistent with other clinical studies of severe neurological disorders, particularly cerebrovascular accidents. The elevated CK-MB activity indicates that ongoing myocardial damage occurs in patients with severe head injury. Although the underlying mechanism is not entirely clear, an excessive release of catecholamines is the most likely mechanism accounting for diffuse myocardial damage, prolonged elevated CK-MB values and the observed ECG abnormalities.

Twelve delayed or recurrent intracranial hematomas were seen in 340 patients with head injuries. Eleven of these hematomas were associated with clotting abnormalities suggesting disseminated intravascular clotting and fibrinolysis (DICF). Seven of 8 delayed traumatic intracerebral hematomas were associated with clotting abnormalities. Two of these were at ventriculostomy sites, which suggests an increased risk of bleeding in association with the insertion of ventricular catheters in patients with DICF. There were 2 delayed epidural hematomas, 1 under a fracture and the other on the side opposite a craniotomy that had been made to treat an intracerebral hematoma, and there were 2 postoperative epidural hematomas. No postoperative hematomas occurred in the absence of DICF. DICF is a major factor in the development of delayed and recurrent intracranial hematomas in patients with head injuries.

The results are presented of a prospective study of the course of 283 spinal cord-injured patients who were consecutively admitted to five trauma centers participating in the Comprehensive Central Nervous System Injury Centers' program of the National Institutes of Health. Of the 283 patients, 14 deteriorated neurologically during acute hospital management. In 12 of the 14, the decline in neurological function could be associated with a specific management event, and in nine of these 12 the injury involved the cervical cord. Nine of the 14 patients who deteriorated had cervical injuries, three had thoracic cord injuries, and two had thoracolumbar junction injuries. Management intervention was identified as the cause of deterioration in four of 134 patients undergoing operative intervention, in three of 60 with skeletal traction application, in two of 68 with halo vest application, in two of 56 undergoing Stryker frame rotation, and in one of 57 undergoing rotobed rotation. Early surgery on the cervical spine when cord injury is present appears hazardous, since each of the three patients with a cervical cord injury who deteriorated was operated on within the first 5 days. No such deterioration was observed following surgery performed from the 6th day on. In two other patients, deterioration did not appear to be related to management but was a direct product of the underlying disease or of systemic complications. Deterioration following hospitalization for spinal cord injury is relatively uncommon--4.9% in this large series. In most instances, decline in function could be attributed to specific management procedures. These changes must not be interpreted as representing failure to provide optimal care but rather should be seen as the inevitable product of an attempt to manage patients with spinal cord and column injuries, many of which are clearly unstable.

The toy BB gun that was commonly available 20 years ago has been modernized into a weapon with lethal potential. We report four children who had intracranial penetration by BBs. Three were shot by another young child, and the fourth child was injured by an intoxicated adult. Two of the children have permanent, severe neurological sequelae. BB rifles should require the same safety precautions and considerations as more traditional firearms.

A 4-month-old female with homozygous achondroplasia and daytime apnea was found to have a small foramen magnum by computerized tomography. Following suboccipital craniectomy and C1-C2 laminectomy respiratory problems did not recur during a 7 month post-operative period. We suggest that the respiratory problems in homozygous achondroplasia may be due to brainstem compression from an abnormally small foramen magnum.

A traumatic epidural hematoma of the cervical spine is reported in a 13-year-old girl. The patient recovered spontaneously over several days without surgical intervention. The diagnosis was made on magnetic resonance (MR) imaging, which also demonstrated subsequent resolution of the hematoma. The etiological factors of spinal epidural hematomas are reviewed and the utility of MR imaging in differentiating other causes of acute spinal cord injury is emphasized.

Three young women who developed amenorrhea secondary to large, unsuspected pituitary tumors are described. They presented with acute onset of the triad of headache, nausea and vomiting, and visual abnormalities. One patient died; the other two retained some sequelae, and one had a significant hemiparesis. These devastating effects of pituitary apoplexy can be avoided in amenorrheic patients if the possibility of a pituitary tumor is considered early on. Lateral skull x-ray examinations are inexpensive an easily obtained and will usually demonstrate significant pituitary tumors. Early recognition and surgical removal of pituitary tumors carries low morbidity and mortality and will avoid an apoplectic crisis.

Four term infants were found by computerized cerebral tomography (CT) to have intraventricular hemorrhage. All were male infants who had experienced substantial intrapartum complications. One infant had subtle clinical signs at 2 days of age; the others had major neurologic findings including seizures and ophthalmoplegia that occurred at 1, 4, and 6 weeks of age, respectively. Three infants in whom the hemorrhages were indistinguishable by CT from those described in preterm infants now have arrested hydrocephalus and normal development. The fourth infant was found to have a large glioblastoma at the site of origin of his initial hemorrhage. These cases emphasize the need to consider this diagnosis in neonates born at term who have abnormal neurologic signs.

Four pediatric patients with mucopolysaccharidoses and an associated carpal tunnel syndrome are presented. Findings in these cases were typical of the adult form of median nerve compression at the wrist, but the patients had minimal symptoms in view of these findings. The importance of careful clinical eximination and early surgical decompression is emphasized.
