A multicentric cooperative study was performed to investigate the factors influencing posttraumatic epilepsy. The patients with fresh head injury from 1983 through 1990 were entered in this study. The cases were divided into two groups and followed-up for five years; the patients with severe head injury and who satisfied the criteria belonged to group I. Those with mild head injury were classified into group II. The criteria for group I was that the patients had one or more of the following risks; disturbance of consciousness, bloody cerebrospinal fluid, focal neurological sign, depressed fracture or basal fracture, abnormal CT, dural tear, early convulsion and/or linear fracture. After drop-out cases were excluded, 191 cases out of 241 were analyzed. The number of cases was 126 (66.0%) for group I and 65 (34.0%) for group II. Sixteen patients (12.7%) of group I developed seizure, whereas nobody of group II experienced seizure. The difference between the patients with and without seizures was analyzed. The statistical significant difference was discovered in the following factors; disturbance of consciousness (GCS and the duration), focal and generalized neurological sign, abnormal CT, multiple risks, intracerebral hematoma, surgery, alcohol drinking and abnormal EEG a month after the injury. The relative risk rates were calculated. The highest risk for posttraumatic seizure was disturbance of consciousness extending over more than one month. This was followed by five other indicators of risk; abnormal EEG at one month, surgery, focal neurological sign, alcohol drinking, generalized neurological sign, and intracerebral hematoma.(ABSTRACT TRUNCATED AT 250 WORDS)

Out of 184 patients with posttraumatic intracerebral haematomas 52 were treated conservatively. For this treatment patients were qualified with good consciousness level, in the range of 13-15 GCS score. Presence of massive neurological deficit was not an indication to treatment. Patients with haematomas in the central zone, with multiple haematomas or with contraindications to operation were treated conservatively. Eight patients died (15%), in 2 of them severe brain trauma with multiple haematomas were the cause of death, in 1 case primary brainstem trauma was present, one patient had deeply situated haematoma of the thalamus and ventricular system, and in 4 cases death was due to non-cerebral causes. The size of the haematoma in CT scan was not decisive for the choice of the treatment. Nearly in all cases compression of the ventricular system was present, but in only some cases the ventricles were shifted. In repeated CT scans resorption of the haematomas was observed. Twenty patients were discharged home in good general condition without serious neurological deficit. Twenty-four patients were treated later on in other hospital departments. Later outpatient control examinations showed that even serious neurological deficits regressed in most cases. The main symptoms were those of the post-trauma syndrome. About 25% of patients had epileptic seizures after the treatment. The author believes that if the patient is conscious and his consciousness is not worsening conservative treatment of intracerebral haematomas may be undertaken with good effects, on condition, however, of the availability of immediate surgical intervention if the condition of the patient is deteriorating.

A retrospective review of 114 solid organ donors over a 6-year period (1982-1987) was undertaken to identify problems in organ donor management and determine outcome of donated organs. Admission GCS was less than or equal to 4 in 84% of the donors. Complications included hypotension (81%), multiple transfusion requirements (63%), diabetes insipidus (53%), DIC (28%), arrhythmias (27%), cardiac arrest requiring CPR (25%), pulmonary edema (19%), hypoxia (11%), acidosis (11%), seizures (10%), and positive bacterial cultures (10%). Only 18% of organs were procured within 3 hours of brain death; 23% were procured more than 6 hours later. Six patients excluded from this study suffered cardiovascular collapse before their organs could be retrieved. From 114 organ donors, consent was obtained to procure 224 kidneys, 77 livers, 62 hearts, 35 pancreata, and ten heart-lung units. All 224 donated kidneys were procured and 202 were ultimately transplanted. Of 77 donated livers, 32 were procured; 31 transplanted. Of 62 donated hearts, 38 were procured; 29 transplanted and nine used for valves. Ten heart-lung units were donated; six were procured and transplanted. Of 35 donated pancreata, 11 were procured; only five were transplanted. Reasons for failure of donated organs to be procured or transplanted included abnormal organ characteristics, lack of compatible recipients, unavailability of surgical teams, organ injury during procurement, intraoperative arrest, and anatomic limitations precluding multiple organ procurement. This study identifies characteristics of organ donors and common organ-threatening complications. Rapid and continuing resuscitation of clinically brain dead trauma victims is mandatory.(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of this study was to determine the incidence of complications in hospitalized patients with normal cranial computed tomographic (CT) scans following minor head injury (Glasgow Coma scale of 13-15). Seventy-three patients were included in the analysis, with 63 children being assigned a GCS score of 15 at presentation. Seventy-one percent of patients were male, and motor vehicle accidents accounted for 56% of the injuries. Forty patients reported loss of consciousness (LOC) following the accident. The mean length of hospital stay was 1.69 +/- 0.94 days. GCS scores, history of LOC, vomiting, or seizures did not significantly influence length of hospitalization. None of the patients developed complications, and all were discharged in good condition. We conclude that a child with minor head injury, GCS score of 15, and a normal neurologic examination and cranial CT scan can be safely discharged to the care of a responsible adult and can be observed at home.

The ideal treatment of children with head trauma would include prevention of posttraumatic seizures. Ninety-two of 937 children with head injuries (9.8%) experienced posttraumatic seizures. In 94.5% of these patients (87 of 92), seizures developed within the first 24 hours after injury. Three children convulsed between 24 hours and 7 days, but only 2 children developed seizures after the 1st week. Factors found to influence the likelihood of seizures included severe head injury (GCS, 3 to 8), diffuse cerebral edema, and acute subdural hematoma (P less than 0.001). Seizures occurred in 35% of severely head-injured children compared to 5.1% with minor head injury (P less than 0.001). A less significant correlation (P less than 0.1) was noted between seizures and open, depressed skull fractures. We found no significant correlation between seizure occurrence and numerous other factors including age, sex, fracture location and type (other than open, depressed fractures), parenchymal injuries, fixed neurological deficits, and cranial operation. Based on our observations, we recommend the prophylactic use of anticonvulsants in children at higher risk for posttraumatic seizures: those with diffuse cerebral edema, acute subdural hematoma, open, depressed skull fracture with parenchymal damage, or severe head injury (GCS less than or equal to 8).

The rural CGW population has not yet undergone the metamorphosis experienced by its urban counterparts. Reminiscent of a past era, suicides far outweight homicides. Although many rural firearm injuries involve hunting accidents, these comprise only a small fraction of CGW at best. Similarly, although many rural firearm injuries involve shotguns or rifles, few CGW result from these weapons. Although the number of patients is small, those with shotgun or rifle injuries manifest lower mortality rates. The authors have confirmed the notion that caliber of civilian weapons is difficult to correlate with outcome. The geographic size of the rural catchment area is an important consideration because it must select a population able to withstand transfer. The authors noted an inverse relationship between length of time before arrival at the facility and mortality. The selection phenomenon probably accounts for the reduced mortality found in the authors series versus most others. Prognostic features of individual gunshot wounds are likely to be similar among varied populations when circumstances of the injury are matched. Thus, one expects similar features on initial examination and CT scan to have similar predictive value. The authors confirmed that CGS and specific deficits were strong predictors of outcome. No patient with a GCS score of 5 or less on admission survived. Absent pupillary response, absent brain stem function, presence of respiratory drive or cough only, and posturing were strong indicators of impending death. The authors confirmed the prognostic value associated with CT evidence of intraventricular hemorrhage, transventricular trajectory, transtentorial herniation, massive edema, and bihemispheric injury. Interestingly, presence of extensive facial fractures, an indicator of trajectory, suggested better outcome. Subarachnoid hemorrhage did not reach prognostic significance. Roughly half of the authors' patients had positive serum ethanol levels, although the test was unable to discern prognosis. Abnormality of any coagulation parameter and frank disseminated intravascular coagulation were correlated with poor outcome. Likewise, thrombocytopenia occurring within the first 24 hours was an indicator of poor prognosis. Although prophylactic antibiotics were not used in all cases, the authors encountered no deep or superficial infections in surviving patients. The prevalence of seizures in the authors' series despite prophylactic AED is unusually high. This feature merits further study.

The severity of the acute intoxication from buflomedil, a vasodilator with papaverinic and alpha-adrenolytic effects, remains generally underestimated. We report the case of a 18-year-old girl who ingested a high amount of buflomedil. Two hours later, she developed seizures and ventricular arrhythmias. On admission to the ICU, she was in circulatory arrest followed by deep coma with mydriasis (GCS = 3). Buflomedil blood concentration, 2 hours after admission, was 97.3 mg.L-1. Toxicological screening for other drugs was negative. Therapy included external chest compressions tracheal intubation, mechanical ventilation, epinephrine and gastric lavage. The haemodynamic status improved within the first 24 h, although she remained comatose until the fifth day. She was discharged the eight day after her admission. This observation demonstrates that the potential severity of buflomedil poisoning is mainly due to early cardiac complications. Treatment remains purely supportive.

Modern populations are constantly exposed to a variety of compounds in the workplace and the environment that promote formation of reactive oxygen species (ROS) within susceptible tissues. Due to its high oxygen consumption, the brain may be particularly vulnerable to oxidative damage and degeneration. Agents that impact cellular oxidative homeostasis would therefore be expected to alter the toxicity of ROS generating compounds. We are testing this hypothesis using endogenous stress hormones, glucocorticoids, to perturb neuronal homeostasis, and adriamycin to generate ROS. Glucocorticoids (GCs) are hormones secreted by the adrenals in response to stress, and are also prescribed clinically to control inflammatory and autoimmune disorders in millions of people annually. Therefore, high GC levels may not be uncommon in individuals exposed to low levels of toxic compounds. Also, GCs appear to act on cellular pathways relevant to ROS as seen by their potentiation of neurodegeneration following insults such as stroke, hypoglycemia and seizure. Using rat primary neuronal culture, we determined neuronal susceptibility to adriamycin toxicity by cell counting (using MAP-2 staining). Dichlorofluorescein fluorescence confirmed ROS generation after adriamycin administration. Physiological levels of GCS (up to mM concentrations) in the culture media exacerbated both adriamycin toxicity and ROS generation. We hypothesize that GCs may exacerbate the toxicity of three neurotoxins whose mechanisms of action overlap GC pathways.

The clinical course of patients admitted following minor head injuries (Glasgow Coma Score [GCS] 13-15) has been studied less extensively than in severely head injured patients. Admission criteria, methods and indications for radiological evaluation are controversial. To study this further, a retrospective review of 633 patients admitted following such injuries to King Khalid University Hospital between 1986 and 1993 was undertaken. Their ages ranged from one month to 80 years (average 17 years). The mechanisms of injury were mainly falls in 339 (53.5%) cases and road traffic accidents in 234 (37%). None of the cases resulted from a non-accidental injury. Radiological evaluation was by skull radiography in 616 (97.3%) cases followed by CT scan in 131 (20.7%). These studies revealed a skull fracture in 78 (12.7%) cases. Six of these 78 patients with skull fracture required a neurosurgical procedure during the first week post injury. These represented 0.97% of the cases who had skull radiographs. A base of skull fracture was an ominous sign, since 3 of the 5 cases with such fractures required ventilation of which one resulted in the only mortality of this series, the fourth developed meningitis. Of the cases studied, 3 (0.5%) developed growing skull fractures all had the initial injury during their first year of life. Other complications were as follows: 25 (3.9%) early post-traumatic seizures, 10 (1.6%) chronic subdural haematomas, 9 (1.4%) extradural haematomas, 2 (0.3%) post-traumatic hydrocephalus and one (0.2%) cerebral abscess. We conclude that patients who have an abnormal GCS, a neurological deficit, post-traumatic seizure, signs or suspicion of basal or depressed skull fracture should be admitted for observation because of the risk of deterioration. Patients with a history of loss of consciousness or amnesia without any of the previous may be discharged to be observed at home by a competent observer, otherwise, will need admission for observation. Radiological evaluation once indicated must be by CT scan. There is no benefit from immediate skull radiography in the initial evaluation of minor head injuries. The indications for CT are an abnormal GCS, presence of neurological deficit, signs of basilar or depressed fracture and persistent or progressive headache or vomiting. Infants with minor injuries should be followed up at least once after two to three months for possible growing fractures.

Children commonly develop diffuse cerebral swelling after traumatic brain injury (TBI) which is believed due to a secondary response to the injury. Near infrared spectroscopy (NIRS), a continuous, direct, and noninvasive monitor of cerebral oxygenation and cerebral blood volume (CBV), could be helpful in understanding these secondary responses. The aims of our study were to determine whether NIRS used in children with severe TBI will provide insight into the pathophysiology of injury. Ten children (1 mo to 15 years old) with severe TBI (admission GCS < or = 7) were continuously monitored by NIRS by placing optodes over the frontalparietal region. Relative values of oxyhemoglobin (HbO2), deoxyhemoglobin (Hb), and total hemoglobin (THb) were obtained and compared to intracranial pressure (ICP), mean arterial pressure (MAP), electroencephalography (EEG), and arterial PCO2 (PaCO2). Episodes of intracranial hypertension (ICP > 20 Torr [T]), changes in ICP > 10 T, changes in PaCO2 > or = 8 T, and changes in MAP > 20 T frequently resulted in changes in HbO2, Hb, and THb. Hyperventilation with decreased PaCO2 always resulted in cerebral oxygen desaturation irregardless of ICP. Often, high ICP correlated with increased THb and HbO2 indicating increased CBV and cerebrovascular dilatation. In two children, posttraumatic seizures were preceded by an unexplained rapid cerebral hyperoxygenation several hours prior to the onset of the clinical seizures. NIRS reliably detects changes in cerebral hemodynamics in children and may be used to further understand the etiology of the diffuse cerebral swelling seen in children after severe TBI.
