Utilization of mental health services in pediatric patients surviving penetrating trauma resulting from interpersonal violence. Am J Surg 2021; 221:233-239. [PMID: 32690211 PMCID: PMC7736092 DOI: 10.1016/j.amjsurg.2020.06.031] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 06/16/2020] [Accepted: 06/22/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Violent trauma has lasting psychological impacts. Our institution's Community Violence Response Team (CVRT) offers mental health services to trauma victims. We characterized implementation and determined factors associated with utilization by pediatric survivors of interpersonal violence-related penetrating trauma. METHODS Analysis included survivors (0-21 years) of violent penetrating injury at our institution (2011-2017). Injury and demographic data were collected. Nonparametric regression models determined factors associated with utilization. RESULTS There was initial rapid uptake of CVRT (2011-2013) after which it plateaued, serving >80% of eligible patients (2017). White race and higher injury severity were associated with receipt and duration of services. In post-hoc analysis, race was found to be associated with continued treatment but not with initial consultation. CONCLUSION Successful implementation required three years, aiding >80% of patients. CVRT is a blueprint to strengthen existing violence intervention programs. Efforts should be made to ensure that barriers to providing care, including those related to race, are overcome.

Abstract
Two main procedures are performed on patients suffering from colonic perforation, diverting colostomy and primary tissue repair. We investigated patient race, ethnicity, and socioeconomic status (SES) that predicted surgical outcomes after blunt or penetrating trauma. A retrospective analysis was performed using data from the National Trauma Data Bank for three years (2013-2015). We identified patients who presented with primary colonic injury and subsequent colon operation (n = 5431). Operations were grouped into three classes: colostomy, ileostomy, and nonostomy. Multiple linear and logistic regressions were performed to assess how race and insurance status are associated with the primary outcome of interest (ostomy formation) and secondary outcomes such as length of stay, time spent in ICU, and surgical site infection. Neither race/ethnicity nor insurance status proved to be reliable predictors for the formation of an ostomy. Patients who received either a colostomy or ileostomy were likely to have longer stays (OR [odds ratio]: 5.28; 95% CI [confidence interval]: 3.88-6.69) (OR: 11.24; 95% CI: 8.53-13.95), more time spent in ICU (2.73; 1.70-3.76) (7.98; 6.10-9.87), and increased risk for surgical site infection (1.32; 1.03-1.68) (2.54; 1.71-3.78). Race/ethnicity and SES were not reliable predictors for surgical decision-making on the formation of an ostomy after blunt and penetrating colonic injury. However, the severity of the injury as calculated by Injury Severity Score and the number of abdominal injuries were both associated with higher rates of colostomy and ileostomy. These data suggest that surgical decision-making is dependent on perioperative patient presentation and, not on race, ethnicity, or SES.

Abstract
A study was undertaken to assess the prevalence of body piercing (BP) in women attending a sexually transmitted disease (STD) clinic, and any associated demographic, socioeconomic and sexual indicators. One hundred and fifty-two new female patients attending the Southampton clinic were the subjects of the study; of these 52 (32%) had BP, the most common site being the navel (25%). BP was more common in women who had their ears pierced more than once (35:71, 49%). It was less common in women who were non-smokers, being present in 17:77 (22%), and in older women, only one of 18 (6%) women aged 35 or older having had BP done. The presence of BP was not associated with socioeconomic class, method of contraception, multiple partners, or the presence of any genital infection. The study supports the suggestion that most BP is done for fashion reasons.

Common experiences of pain in children and adolescents--an exploratory factor analysis of a questionnaire. SWEDISH DENTAL JOURNAL 2013; 37:31-38.

Abstract
The aim of the study was to reduce everyday and dental treatment pain items included in the extended Children's Pain Inventory (CPI), used in a prior study on Swedish children and adolescents. Another aim was to, by means of exploratory factor analysis (EFA), expose hitherto undiscovered dimensions of the CPI pain variables and thus to improve the psychometric properties of CPI. As some pain items are relevant merely to some individuals, a new and more useful questionnaire construction would enhance the internal validity of the instrument in observational surveys. EFA was applied on the extended CPI instrument. 368 children, 8-19 years old, had answered a questionnaire comprising 10 dental and 28 everyday pain variables. These pain items were analysed using a series of sequentially implemented EFA. Interpretations and decisions on the final number of the extracted factors was based on accepted principles; Kaiser's Eigenvalue >1 criterion, inspection of the scree plot and the interpretability of the items loading. The factors were orthogonally rotated using the Varimax method to maximize the amount of variance. Of all tested EFA models in the analysis, a two, three, four, and five factor model surfaced. The interpretability of the factors and their items loading were stepwise examined; the items were modulated and the factors re-evaluated. A four factor pain model emerged as the most interpretable, explaining 79% of the total variance depicting Eigenvalues > 1.014. The factors were named indicating the profile of the content: Factor I cutting trauma to skin/mucosal pain, Factor II head/neck pain, Factor III tenderness/blunt trauma pain, Factor IV oral/dental treatment pain.

Abstract
Distinguishing deliberate self-inflicted body damage from assault represents a challenge to the forensic expert. Identifying a wound as self-inflicted can be particularly difficult in emergency room situations. We present the case of an individual who self-inflicted three bullet wounds, allegedly related to a shooting incident. This individual was lacking any overt psychopathology. When confronted with the facts, he confessed and explained his motivation. It is known that self-mutilation behavior can be related to particular, well systematized psychiatric disorders. However, in the absence of such a diagnosis, every suspicious wound should be carefully considered by the forensic expert as potentially self-inflicted with the intent by the "victim" of obtaining secondary gains.

Abstract
Penetrating heart injuries can be lethal. Here we report a case of self-inflicted cardiac injury with glass fragments by a psychiatric patient. The patient presented with cardiogenic shock and was initially treated surgically for a large pneumothorax and cardiac tamponade. A few days later she presented with dyspnoea and hypotension. An echo-Doppler study was performed and an acquired post-traumatic ventricular septal defect (VSD) with left-to-right shunt was diagnosed. The patient was transferred to theatre where the defect was successfully repaired. Post-traumatic VSD is a rare complication of penetrating heart injuries and has a tendency to present late. Follow up of such cases is recommended with repeat echocardiography.

Abstract
We aimed to identify the meanings constructed about occupational risk by health workers through the structural approach to social representation. 220 health professionals from a public hospital in Natal, Rio Grande do Norte, Brazil, participated in this research. The technique of free evocation of words was used and data were examined through an articulated analysis of frequency average and evocation order Results shows that central systems have different compositions in three groups: disease and death for doctors, perforating and danger for nurses and contamination, disease, infection and danger for dentists. The complexity of bond among work and risk suggests that strategies and alternatives of actions might be operationalized with integration of different professional categories and fields of knowledge towards a common objective starting from an interdisciplinary space and expanding the awareness level of these professionals concerning to consequences of their practices to health.

Abstract
This study examines the cross-lagged relationships between posttraumatic distress symptoms and physical functioning, using a sample of 413 persons who were hospitalized for injuries resulting from community violence. Posttraumatic distress was assessed at 1 week, 3 months, and 12 months postinjury, and posttraumatic physical functioning was assessed at 3 months and 12 months. Structural equation modeling was used to assess the prospective relationship between posttraumatic distress symptoms and physical functioning while controlling for demographic characteristics and objective measures of injury severity. Results indicate that posttraumatic distress and physical functioning are reciprocally related. Individuals with high levels of psychological distress at 1 week posttrauma have worse physical functioning at 3 months. Psychological distress at 3 months was not significantly associated with subsequent change in physical functioning at 12 months. Individuals with poor physical functioning at 3 months had higher than expected levels of psychological distress at 12 months. These findings demonstrate a reciprocal relationship between physical and mental health following traumatic injury. Interventions targeting physical recovery may influence subsequent mental health, and therapies aimed at improving early mental health may also have long-term benefits for physical recovery.

Abstract
There are substantial data to suggest that stress-induced disruption of neuroendocrine immune equilibrium is detrimental to health, with the strongest evidence to date in wound healing. Murine and human studies demonstrated that the down-regulation of the early inflammatory response by an increase in cortisol levels results in delayed wound repair and identified several potential cellular mechanisms linking stress and wound healing. The impact of stress on wound healing has been studied almost exclusively in acute experimentally induced wounds. Because chronic wounds are different entities from acute wounds, the cellular/molecular mechanisms by which stress affects acute wound healing may not necessarily be applied to chronic wounds, hence, the need for studies in stress and chronic wound (eg, diabetic foot ulcer) healing.

Profound hypothermia is superior to ultraprofound hypothermia in improving survival in a swine model of lethal injuries. Surgery 2006; 140:307-14.

Abstract
BACKGROUND Rapid induction of profound hypothermia can improve survival from uncontrolled lethal hemorrhage. However, the optimal depth of hypothermia in this setting remains unknown. This experiment was designed to compare the impact of deep (15 degrees C), profound (10 degrees C), and ultraprofound (5 degrees C) hypothermia on survival and organ functions. METHODS Uncontrolled lethal hemorrhage was induced in 32 swine (80-120 lb) by creating an iliac artery and vein injury, followed 30 minutes later by laceration of the descending thoracic aorta. Hypothermia was induced rapidly (2 degrees C/min) by infusing cold organ preservation solution into the aorta through a thoracotomy. The experimental groups were (n = 8 per group): a normothermic control, and 3 hypothermic groups in which the core temperature was reduced to 15 degrees C, 10 degrees C, and 5 degrees C. Vascular injuries were repaired during 60 minutes of hypothermia. Animals were then rewarmed (0.5 degrees C/min) and resuscitated on cardiopulmonary bypass, and monitored for 6 weeks for neurologic deficits, cognitive function, and organ dysfunction. RESULTS All normothermic animals died, whereas 6-week survival rates for the 15 degrees C, 10 degrees C, and 5 degrees C groups were 62.5%, 87.5%, and 25%, respectively (P < .05: normothermic vs 15 degrees C and 10 degrees C; 10 degrees C vs 5 degrees C). The surviving animals from the 15 degrees C and 10 degrees C groups were neurologically intact, displayed normal learning capacity, and had no long-term organ dysfunction. The survivors from the 5 degrees C group displayed slower recovery and impaired cognitive functions. CONCLUSIONS In a model of lethal injuries, rapid induction of profound hypothermia can prevent death. The depth of hypothermia influences survival, with a better outcome associated with a core temperature of 10 degrees C compared with 5 degrees C.

Abstract
The purpose of the present paper was to examine the differences in clinical features between self-cutters and self-burners, to clarify clinical implications of self-mutilating behaviors other than self-cutting. Subjects were 201 delinquent adolescents consecutively entering a Japanese juvenile detention center from February 2003 to March 2003. The subjects were assessed using a self-reporting questionnaire to evaluate self-mutilation, traumatic events, and problematic behaviors. Beck Depression Inventory-2 (BDI-2) and Adolescent Dissociative Experience Scale (A-DES) were also tested. Subjects were classified into four groups according to self-mutilating behaviors: non-self-cutting or -burning (NSCB), self-cutting (SC), self-burning (SB), and self-cutting and self-burning (SCB). The questionnaire answers and scores of the BDI-2 and A-DES were compared between the four groups. Of 201 subjects, 33 (16.4%) had cut their wrists or forearms at least once, and 72 of 201 (35.8%) had burned themselves at least once. The SC and SCB group had traumatic events, problematic behavior, and various types of self-mutilating behavior more frequently than the other two groups. The SCB group reported additional types of self-mutilating behavior more than the SC group. The SCB group also experienced multiple body customizations compared to the SC group, and exhibited higher scores on the BDI-2 and A-DES than the other three groups. The self-burning without self-cutting may have limited clinical implications. However, the self-burning with self-cutting may suggest depression and dissociation, as well as possible indication of self-mutilating behavior.

Abstract
Psychological and psychophysiological investigation of the casualties with injured extremities was conducted in 3-5 and in 30-40 days after being wounded. It has shown that during stay in clinic some dynamics in their psychic state was observed. Marked asthenization was the leading sign in the initial treatment period. That's why it is reasonable to use not exhausting projective methods and some short questionnaires (scales) at this stage. In a month after starting treating the casualties the aggressive tendency, mood decrease, increase in the reactive anxiety level, sympathetic tonus of vegetative nervous system were coming into the foreground. It characterizes the development of posttraumatic stress disorders. Gradual increase in the casualties' activity is also typical of the hospital treatment period. That's why the psychological and psychophysiological investigation can be supplemented with volumetric personal tests.

Abstract
The purpose of this study was to investigate the role of peripheral macrophages in the generation of mechanical allodynia utilizing a modification of the Chung rat model of neuropathy. Three distinct methods were used: (1) systemic and perineural macrophage inhibition utilizing CNI-1493; (2) depletion of the peripheral macrophage population by liposome-encapsulated clodronate; and (3) perineural administration of activated or inactivated bone marrow-derived macrophages (BMDM) in sham-surgery rats. Mechanical allodynia was tested on days 1, 3, 5, 7, and 10 post-intervention or surgery using von Frey monofilaments. In order to assess the role of spinal glia following these interventions, microglial (CNS macrophages) and astrocytic activation was assessed using immunohistochemistry. CNI-1493 did not attenuate mechanical allodynia, or spinal glial expression as compared to the saline control group. Similarly, the clodronate depletion of peripheral macrophages prior to nerve injury did not have any effect on the resultant mechanical allodynia or spinal glial activation. Perineural administration of activated or inactivated BMDM did not evoke mechanical allodynia in sham surgery rats. Of interest, we observed an ipsilateral, dorsal horn increase in microglial expression following perineural administration of activated macrophages. In summary, these data suggest a limited role of activated macrophages in the onset of mechanical allodynia in an animal model of neuropathy.

Abstract
Octylcyanoacrylate (Dermabond) is approved by the Food and Drug Administration for laceration closure. International studies have shown its utility in wound closure and have shown it to be as good or better than suture closure for speed, patient preference, and cosmesis, with no difference in the rate of dehiscence or infection. We sought to determine whether it retains its tensile strength, durability, and skin apposition when an athlete is allowed to reenter competition, where it is subject to recurrent stress, moisture, and trauma. The study was performed at two professional hockey sites. Wounds were anesthetized, irrigated, and debrided. The skin was closed with Dermabond. The athlete was returned immediately to competition. Wounds were examined at the end of competition and again at 7 days. A total of 32 lacerations on 28 players were studied. The mean size of laceration was 2.3 cm (range 0.8 cm to 4.5 cm). The majority (95%) of wounds were on the face. Of the 32 lacerations, 31 (97.6%) had good results at the conclusion of the game. Of these 31, all had good results at 7 days following repair. Dermabond retained its strength, durability, and skin apposition when the athlete was allowed to reenter competition following wound repair.

Abstract
OBJECTIVE Posttraumatic Stress Disorder (PTSD) impairs outcome from injury. We present a path analysis of factors related to the development of PTSD in injured adults. METHODS A prospective cohort of 250 patients without severe neurotrauma was evaluated by interview during admission and by mailed self-report 6 months later. Data were gathered from the trauma registry (age, injury mechanism, and Injury Severity Score), social history (gender, income, education, and social support), and survey instruments. Baseline assessment used the Michigan Critical Events Perception Scale (peritraumatic dissociation and subjective threat to life), the Life Experience Survey (stressful exposure history), and the SF36 (general and mental health). PTSD at 6 months was identified with the civilian Mississippi Scale for PTSD. Data are listed as mean +/- SEM or percent (%). Path analysis was conducted by linear regression and significant (p<0.05) variables are shown. Factors are listed with the standardized beta. A negative beta suggests a protective effect. RESULTS The 176 patients (72%) who completed the 6-month follow-up were 37.7+/-0.88 years old; 75% were men; and blunt (70%), penetrating (13.5%), and burn (16.4%) mechanisms caused the injuries. Assault was involved in 14.5% of the cases. Average income was $44,300+/-2,700/yr, education was 13.0+/-0.15 years, and Injury Severity Score was 13.9+/-0.50. A total of 42.3% of the patients developed PTSD. The 39.7% of the variance in PTSD explained by the model was due to intentional injury (beta = 0.27), male gender (beta = -0.21), age (beta = -0.20), peritraumatic dissociation (beta = 0.174), baseline mental health (beta = -0.21), and prior life-threatening illness (beta = -0.29). Peritraumatic dissociation was due to the patient's sense of threat to life (beta = -0.47), and threat was related to Injury Severity Score (beta = 0.2), assault(beta = 0.14), education (beta = -0.15), and age (beta = -0.19). Baseline SF36 mental health was related to social support (beta = 0.27) and income (beta = 0.21). Income was contingent on education (beta = 0.21). CONCLUSION PTSD occurred in 42.3% of injured adults 6 months after trauma and was related to assault, dissociation, female gender, youth, poor mental health, and prior illness. By modeling PTSD, we may learn more of the etiology, risk stratification, and potentials for the treatment of this common and important morbidity of injury.

Abstract
BACKGROUND Management of penetrating colon injuries in the presence of multiple associated risk factors is controversial. Issues not considered in previous management strategies are patient perception of quality of life with a colostomy and the true cost of each therapeutic option, which includes colostomy supplies and costs of colostomy takedown. To evaluate these issues, we performed a cost-utility analysis. METHODS We constructed a decision tree with 3 options: primary repair, resection and anastomosis, and colostomy. Chance and decision nodes on each decision branch represent injury severity, complications, colostomy takedown, and death. Chance node frequencies and utility assignments were taken from published data. We obtained actual costs for all components of perioperative care. The outcomes reported are cost and quality of life. RESULTS Colostomy has the least quality of life and the greatest cost. Primary repair and resection each dominate colostomy in the baseline analysis. No variable significantly altered these conclusions in sensitivity analyses. CONCLUSIONS Simple suture or resection and anastomosis at the time of initial exploration is the dominant management method for penetrating colon trauma. It also demonstrates the trade-off between cost and life expectancy of the 3 management options.

Abstract
Brachial plexus injury leading to spinal cord root avulsion in humans produces a characteristic constant crushing and intermittent shooting pain, which is often intractable. Preliminary observations suggested that this pain might be alleviated after successful nerve transfers to restore limb function. We therefore studied a group of 14 patients prospectively, to establish the validity of this observation, and to elucidate the underlying mechanisms. We found a strong correlation and temporal relationship between reduction in pain and successful nerve repair. All five patients with motor recovery experienced significant relief of de-afferentation pain, while in the seven patients with persistent pain, none had motor recovery. There was no correlation between pain relief and the minimal recovery of sensation in some cases, and no case had any return of sensory or sympathetic cutaneous axon-reflexes. While skin sympathetic axon-reflexes were reduced with T1 root lesions, there was no relationship between T1 root damage and pain. It was concluded that nerve repair can reduce pain from spinal root avulsions and that the mechanism may involve successful regeneration, and/or restoration of peripheral connections prior to their function, possibly in muscle.

Abstract
The study reports on 65 refugees with diagnoses of posttraumatic stress disorder (PTSD) and manifest suicidal behavior (40% had suicide attempts; 29% detailed suicide plan; 31% recurrent suicidal thoughts). Our hypothesis was that the predominant kind of stressful experience in PTSD patients might be reflected in their choice of method when pondering or attempting suicide. Relationships were found to exist between the main stressors and the respective subjects' preference for suicide method. Particularly among PTSD patients with a history of torture, an association was found between the torture methods that the victim had been exposed to, and the suicide method used in ideation or attempts. Blunt force applied to the head and body was associated with jumping from a height or in front of trains, water torture with drowning, or sharp force torture with methods involving self-inflicted stabbing or cutting. Relationships between main stressors and content of suicidal ideation are discussed.

Abstract
The prefrontal cortex plays an especially important role in human social-cognitive behavior. It has been difficult to quantify deficits in this domain in patients with frontal lobe lesions using standardized psychological instruments. We administered the Everyday Problem Solving Inventory (EPSI), which is composed of a range of scenarios depicting everyday social problems and their possible solutions, to a group of patients with frontal lobe lesions who were required to rate each of 4 possible solutions to each problem for their effectiveness. Our sample consisted of 27 normal controls (NCs), 33 patients with focal frontal lobe lesions (FLL), and 3 patients with frontal lobe dementia (FLD). The performance of the FLL patients on the EPSI instrument was also compared with their performance on traditional neuropsychological tests. The results indicated that the FLD patients' EPSI rank ordering of social problem solutions was uncorrelated with the performance of NCs and about half of the FLL patients EPSI rank orderings of solutions also varied substantially from those of the NCs. These same FLL patients also had the lowest scores, compared to FLL patients whose judgements on the EPSI were similar to that of the NCs, on a set of neuropsychological tasks sensitive to frontal lobe dysfunction. There was no obvious relationship between locus of lesion within the frontal lobes and performance on the EPSI. These results suggest that some patients with prefrontal lobe lesions may have impaired social judgement that can be directly revealed through the use of a conventional psychological inventory such as the EPSI.

Abstract
The WF Caveness Vietnam Head Injury Study includes over a thousand men who survived penetrating head injuries during the Vietnam War and on whom detailed medical and follow-up data are available. This population offers unique opportunities for the study of recovery from brain injury and of brain structure-function relationships. The authors briefly review long-term outcome in this cohort with respect to traumatic unconsciousness, post-traumatic epilepsy, and elements of psychologic and psychosocial function, including returning to work.

Abstract
Several strains of autoimmune mice spontaneously develop molecular layer ectopias that are similar in appearance to those seen in humans and are caused by disturbances in neocortical neuronal migration. These mice also exhibit behavioral anomalies, some of which correlate with ectopias, others with the immunological disorder. In this study, we induced neocortical ectopias (via puncture wounds) and microgyria (via freezing lesions) in the neocortex of 1-day-old (newborn) mice without immune disorders in an attempt to further disentangle the effects of autoimmunity and of cortical malformation on behavior. In addition, we wished to compare the behavioral effects of small ectopias to larger microgyric lesions. DBA mice were assigned at birth to receive either a puncture wound or freezing lesion of either the left or right hemisphere. An independent group was subjected to sham surgery. In adulthood, these mice were given a battery of tests designed to measure lateralization and learning capacity. Lesioned mice (irrespective of hemisphere or type of damage) performed poorly when compared to sham-operated animals in discrimination learning, in a spatial Morris Maze Match-to-Sample task, and in a Lashley Type III maze. In shuttlebox avoidance conditioning, where immunological disorder has been shown to compromise behavioral performance in autoimmune mice, there was no difference between lesioned and sham animals. These results (1) support the dissociation between the effects of developmental neocortical anomalies and autoimmune disease on behavior (2) reveal similarities between spontaneous and induced neocortical malformations and (3) fail to support a difference in behavioral effects between ectopias and microgyria.

Abstract
When the landmark patient Phineas Gage died in 1861, no autopsy was performed, but his skull was later recovered. The brain lesion that caused the profound personality changes for which his case became famous has been presumed to have involved the left frontal region, but questions have been raised about the involvement of other regions and about the exact placement of the lesion within the vast frontal territory. Measurements from Gage's skull and modern neuroimaging techniques were used to reconstitute the accident and determine the probable location of the lesion. The damage involved both left and right prefrontal cortices in a pattern that, as confirmed by Gage's modern counterparts, causes a defect in rational decision making and the processing of emotion.

Abstract
Reports of intracranial self-mutilation by psychotic individuals are associated with severe mental disorders, criminality, or both. We describe a psychotically depressed male who drove a ballpoint pen through his right medial canthus and into his intracranial compartment. The patient developed a cavernous sinus syndrome and a traumatic dissection of the cavernous portion of the carotid artery. The pen was removed intraoperatively. Postoperatively, the patient was placed on a course of broad-spectrum antibiotics, antidepressants, and antipsychotic medications, and he has received long-term psychiatric follow-up. The literature related to these unusual cases is reviewed, and relevant surgical, medical, and psychiatric aspects of treatment are discussed.

Abstract
Few investigators have studied whether the behavioral effects of brain insult in adulthood are stable after the period of maximum recovery. We addressed this issue in a 30-year longitudinal study of 84 veterans of World War II, 57 with penetrating head injury (HI) and 27 with peripheral nerve injury (PNI), matched with respect to age, premorbid intelligence, and premorbid education. Each subject was examined during the 1950s and during the 1980s; each examination included the largely verbal Army General Classification Test (AGCT) (with Vocabulary, Arithmetic, and Block Counting subscales) and the Hidden Figures Test (which measures figure-ground discrimination). HI exacerbated decline in performance over time, irrespective of lesion site or cognitive test. HI and PNI subjects differed significantly (p less than 0.05) in AGCT Total and Arithmetic change scores, and means were in the same direction for all other measures. In analyses contrasting subjects in each of the eight lesion groups to PNI subjects, those with left parietal lobe injuries showed significantly greater decline from the 1950s to the 1980s on the Vocabulary and Arithmetic subscales of the AGCT, as did those with left temporal lobe injuries on the Arithmetic subscale, whereas subjects with right parietal lobe injuries showed significantly greater decline on the Hidden Figures Test. We hypothesize that the observed reduction of cognitive capacities late in life was due to some combination of HI in young adulthood, secondary effects of the injury occurring with time, effects of stress on remaining brain tissue caused by functioning for decades in a compromised state, and changes in the brain occurring with age. Although the HI subjects were not demented, follow-up studies must assess whether exacerbated decline is a harbinger of dementia.

Abstract
Adult, male Sprague-Dawley rats received 100 mg/kg Ginkgo biloba extract (GBE) intraperitoneally for 30 days. GBE reduced overall activity and decreased sensitivity to light in the open field maze. The rats were also less responsive to noxious stimuli after 13 days of treatment with GBE. After the last injection, all subjects were trained on a delayed-spatial alternation task. Subsequent to acquisition of the spatial task, the rats received either sham operations and saline or bilateral frontal cortex lesions treated with either saline or GBE. Thirty additional days of treatment began on the day of injury, and open field behavior, analgesia, and metabolic activity measurements were again measured. The rats with lesions treated with saline were more active than their GBE-treated counterparts and sham controls but there were no differences in response to illumination or noxious stimuli. Retention of the delayed-spatial alternation indicated that rats with lesions treated with GBE were less impaired than brain-injured subjects receiving saline treatment. Histological examination showed that GBE reduced the extent of brain swelling in response to the injury.

Abstract
A prison inmate was referred to us for diagnostic procedures and therapy due to a combination of pneumomediastinum with emphysema of neck and face. External injuries were absent and pathogenesis remained uncertain until thorough examination of the patient revealed two intraoral wounds, presumably from a needle, reaching into the maxillary sinus. This large subcutaneous emphysema of the face, neck and mediastinum was the result of an exaggerated Valsalva maneuver. With this self-inflicted injury, unknown to us, the prisoner achieved the desired immediate admission to hospital.

Abstract
Men with chronic, focal, unilateral missile injures of the brain--twenty-five with left hemisphere lesions (LH group) and twenty with right hemisphere lesions (RH groups)--and twenty-two control subjects were given two visuoperceptual and two visuospatial tests. The LH group was significantly impaired in relation to the control group on both the spatial tasks. A different pattern of dissociable perceptual and spatial deficits was found in the experimental groups: better preserved perceptual than spatial performance was observed more frequently in the LH group whereas the converse--relatively better spatial than perceptual performance--was more evident in the RH group. Double dissociations in performance on the two spatial tasks were found predominantly in the LH group. These findings suggest an important left hemisphere contribution to visuospatial processing and the possibility of a more focal representation of spatial abilities in the left hemisphere than in the right.

Abstract
This study was designed to examine the effects of penetrating head injury upon face discrimination and memory in 213 brain-injured Vietnam veterans and 49 normal controls. Impairment on tests of face memory was most associated with bilateral lesions and with unilateral lesions of the temporal lobe. Impairment on a test of face discrimination was most associated with right hemisphere, and with bilateral lesions which included either frontal or parietal lobe involvement. Performance on these tasks appeared independent of other visuospatial or verbal tasks. Cluster analysis revealed a dissociation between performance on facial memory and facial discrimination tasks.

Abstract
The relationship of preinjury left-hand dominance for motor performance to postinjury distal motor skills following penetrating brain wounds in patients without overt hemiplegia was examined. We studied 13 controls, 13 right-hemisphere brain-damaged patients, and 11 left-hemisphere brain-damaged patients on motor tasks measuring reaction time, strength, and coordination. Our results indicated that no persistent deficits were seen on distal motor tasks in left-handed adults who suffered a penetrating brain wound. These findings are compatible with the relative sparing of persistent neuropsychological deficits in left-handers following brain damage.

Abstract
Studies of deep dyslexia in Japanese patients, and of non-word reading by deep dyslexic readers of alphabetic scripts, suggest a general principle that reading that depends on the mapping of characters onto phonological segments (phonemes in the case of alphabetic scripts, syllables in the case of syllabaries) is impossible in deep dyslexia. We describe a case of deep dyslexia in a patient who premorbidly could read English and Nepalese. As the latter is written in the syllabic Devanagari script, this case may be used to explore the generality of this principle. It would be expected that reading Nepalese words written in the syllabic script would be more difficult than reading English words written in the Roman alphabet. In oral reading tasks this was the case, even though Nepalese was the patient's first language. However, further studies showed that he could understand Nepalese words written in the syllabic script at least as well as English words written in the Roman alphabet, and that he could read aloud Nepalese words written in the Devanagari script, provided he was allowed to respond in English. In addition, naming of pictures was much worse in Nepalese than in English. Therefore this patient's difficulties in reading Nepalese aloud were output difficulties, not difficulties in reading a syllabic script. We argue that the superiority of expressive speech in English over expressive speech in Nepalese arose because the patient had had intensive speech therapy in English and no speech therapy in Nepalese. We also conclude that his reading performance demonstrates that the reading of syllabic scripts is not necessarily abolished in deep dyslexia. The inability of Japanese deep dyslexics to read aloud or comprehend the syllabic script kana is thus not simply a function of this script being a syllabary. This inability therefore remains to be explained.

Abstract
The present experiment examined the ability of subjects with penetrating brain injuries to resolve different forms of linguistic ambiguity. Most subjects with penetrating head wounds of the left cerebral hemisphere (n = 11) had impaired ability to detect linguistic ambiguity even when tested 20 yr. after injury. This decrement in performance was present for all types of ambiguity and was most pronounced in subjects who were dysphasic post-injury (n = 7). A similar pattern was shown by patients with bilateral cortical penetration (n = 11), especially those who were dysarthric or dysphasic (n = 5) immediately after injury. Performance on phonetic and underlying constituent structure ambiguities was more severely affected than performance on lexical, derived constituent structure, and particle-preposition ambiguities. By contrast, patients with right-penetrating cortical lesions (n = 18) performed nearly as well as the normal control subjects (n = 12).

Abstract
Patients with penetrating wounds of the left cerebral hemisphere are inferior to normal control subjects and patients with right hemisphere lesions in their ability to shadow language stimuli presented at various rates. Their performance deteriorates rapidly at higher rates of stimulus presentation. Patients with bilateral cerebral penetration show similar patterns of deficits. The deficits on the shadowing task are especially prominent in patients who were dysphasic or dysarthric during the immediate postinjury period.

Abstract
Physiological and psychological parameters of 20 survivors of penetrating wounds of the heart were examined 7 to 52 months after recovery. All survivors had cardiac complaints. The psychological parameters for hypochondriasis, compulsiveness, and internalization were much greater in the patients than in control subjects but were similar to those in victims of violent major abdominal trauma. Physiological abnormalities were present in 19, although no particular pattern or abnormality could be related with certainty to the type of wound, operative procedure, or postoperative course. One recovered and re-employed victim required late surgical repair of a traumatic ventricular septal defect and ventricular diverticulum. Although functional work capacity measured by stress testing was normal in 90 percent, only eight survivors resumed employment. Complete rehabilitation was impaired by a residual traumatic neurosis. Management goals for patients with penetrating cardiac wounds should be broadened to include prevention of psychological disabilities.
