In an attempt to improve and expedite the care of head-injured children, data have been published recommending burr hole exploration in lieu of computed tomography for children with signs of brain stem compression or with a Glasgow Coma Scale score of 3. Exploratory burr holes revealed a high incidence of subdural hematomas, and removal of the hematomas improved survival. We are reporting 19 consecutive children with Glasgow Coma Scale scores of 3. Coma score evaluation was confounded by intubation, sedation, pharmacological paralysis, and posttraumatic seizures. We found no radiographical or postmortem pathological evidence of intracranial hemorrhage, which would warrant operative intervention. A high incidence of multisystem injuries and high cervical spine injuries would have made early intervention both dangerous and inappropriate. Although there is a definite role for emergency trephination, routine exploratory burr holes for children with a Coma score of 3 is not justified.

1. The effects of the octapeptide angiotensin II (AT II) on some types of behaviour [threshold of seizures induced by timed intravenous infusion of pentylenetetrazol (PTZ), exploratory behaviour: ambulation, rearing and head-dips on a hole-board, and passive avoidance performance--step-through paradigm] were studied following repeated systemic administration of MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) to mice (30 mg/kg, i.p., twice daily for 5 days). AT II was administered s.c. (200 micrograms/kg), single and repeated (for 7 days) 7 days after withdrawal of MPTP. 2. PTZ seizure threshold was significantly increased by AT II both in groups with single and repeated administration (stronger than in the group treated only with MPTP and in the group untreated with MPTP). 3. AT II significantly increased the ambulation and rearing as well as the head-dips both on single and repeated administration as compared to groups treated and untreated with MPTP. 4. Administered immediately after the passive training trial AT II, on single and repeated administration, significantly increased latencies, i.e. it facilitated retention, in MPTP-treated mice. 5. These results were discussed in the light of DA and perhaps, GABA receptor supersensitivity developed in susceptible brain structures after withdrawal of repeated MPTP administration. 6. The adaptive changes in the effects of AT II on seizure threshold, exploratory behaviour and retention of passive avoidance performance might be associated with the altered receptor-receptor (AT II-DA-GABA) interactions in the brain.

Forty one cases of subdural empyema treated between 1977 and 1988 at the Postgraduate Institute of Medical Education and Research. Chandigarh, have been analysed. The patients ranged from 9 days to 80 years of age. There were 22 children, including 11 infants. Fever, altered sensorium and seizures were the most common symptoms present for 1 day to 6 months. Otogenic infection was the commonest aetiological factor followed by postoperative and posttraumatic causes. Thirty seven patients had supratentorial empyemas, including 4 with parafalcine collections, three had infratentorial empyemas, and in one there was extension of the empyema from the supratentorial to the infratentorial compartment. Therapeutic modalities used included percutaneous needle aspirations in infants and burr hole evacuation and craniotomies in adults. A wide spectrum of organisms was detected. Mortality in this series was 24%, which was mainly attributable to the deteriorated neurological status prior to treatment. A detailed review of the literature has been given, highlighting various controversies in the management of SDE. Important prognostic factors and a treatment plan are suggested.

With increasing immigration from endemic regions, the incidence of neurocysticercosis in North America is rising. This retrospective study was undertaken to examine the role of surgery in those cases presenting with large cystic parenchymal and cisternal lesions in the current era of anthelminthic agents administered orally. A total of 237 patients presented with newly diagnosed neurocysticercosis to our institution over a recent 5-year period (mean age, 31.2 years). Among those who presented with cystic mass lesions predominantly affecting the brain parenchyma and cisternal spaces, 20 (8.4%; mean age, 40.2 years) with large cystic lesions subsequently underwent surgical intervention, either because of an emergent presentation or because they were refractory to medical management. Clinical presentation included increased intracranial pressure, focal neurological deficit, and seizure. Radiographic imaging (computed tomography and/or magnetic resonance imaging) demonstrated 12 cases with cisternal lesions, 7 with parenchymal lesions, and 1 involving both compartments. Based on imaging guidelines, 30 operative procedures (excluding shunt revisions) were performed (14 craniotomies, 8 cerebrospinal fluid diversions, 7 stereotactic procedures, and 1 burr hole drainage). Fifteen (75%) showed neurological or symptomatic improvement over a median follow-up period of 36.4 months. There were three surgery-related complications and no deaths.

In humans, limbic epilepsy seems to predispose to anxiety. Attempts to model this phenomenon have shown that limbic kindling increases anxiety in domestic cats. No comparable data exist in rodents. The present study was done to investigate the effects of unilateral medial amygdala kindling in Wistar rats on behaviour in the 'elevated plus maze' test of anxiety. It was found that kindling to stage 5 seizures increased anxious response in the plus maze for at least a week following the last seizure. There were equally long lasting decreases in exploratory motivation in the hole board test, which were unrelated to the change in anxiety in the plus maze. The relevance of these findings to epilepsy, stress and anxiety are discussed.

The patient, a 52-year-old male, experienced a generalized convulsive seizure. Computed tomography (CT) revealed a solitary, noncalcified cyst, 1 x 2 cm in diameter, in the left occipital lobe, without contrast enhancement. No other lesions were found in systemic soft tissues, skeletal muscles, or the eyes. A CT-guided stereotactic biopsy was performed through an occipital burr hole, and the diagnosis was cerebral cysticercosis. Although cysticercosis is still common in Mexico, Chile, and India, its occurrence has rarely been reported in Japan, especially since World War II. Intraparenchymal calcification and cystic lesions are common CT findings. However, in this case, a non-enhancing solitary cyst was the only CT finding. The authors review the literature and discuss the CT features and the usefulness of CT-guided stereotactic biopsy in the diagnosis and treatment of cysticercosis.

Six cases of interhemispheric subdural empyema are reported. It is a rare disease due to different infections origins. All of them are under 24 years old. The characteristics symptoms of these cases were intracranial infection, increased ICP, cerebral falx syndrome and focal seizure. The specific appearances on the films of angiography and CT scan were discussed. It could be located these lesions exactly. The surgical treatments were continuous drainage though cranial burr hole or excision of abscess. All 6 cases are cured with no recurrence.

In a prospective study 144 adult patients with chronic subdural hematomas were randomly divided into three treatment groups after burr-hole evacuation. The two commonly used procedures (external closed system drainage and aspiration and irrigation without any drainage) were compared to a modified technique: permanent subdural drain with subcutaneous reservoir. After the hematoma was washed out with saline solution, a silicon catheter with multiple perforations was introduced into the subdural cavity and connected to a Rickham reservoir, fixed in the frontoparietal burr hole. In patients who showed secondary deterioration or enlargement of the residual hematoma as proven by computed tomographic scan, the reservoir was punctured and the subdural fluid aspirated. The great advantage of this method is that it is practicable at the bedside as well as in the outpatient department, thus making it possible to reduce the number of additional operations. The incidence of symptomatic residual or recurrent hematoma was similar in all three groups. The reoperation rate was 4-fold greater in the groups treated with conventional therapy, when compared to the group with the implanted system. At the same time there was no indication that the implantation of the drain was less safe, as judged by the incidence of seizures and infections.

In order to characterize neurological, intellectual and behavioral sequelae better after surgical treatment of brain abscess in childhood, 32 children were studied over a 10-year time span after treatment of a brain abscess. Depending on the clinical condition, surgical treatment consisted of simple aspiration through a burr hole or of total excision after craniotomy. There were only 3 postoperative deaths (9%). The scheduled time for long-term follow-up was 3 years after surgery. The patient assessment included information concerning the presence of seizures, accurate neurological examination, an EEG, and a battery of intellectual tests to evaluate the presence of behavioral-mental deficits. Late seizures developed in 7 of the 29 survivors. Five patients presented permanent hemiparesis after surgical treatment. It is noteworthy that the intellectual impairment observed was more severe in younger patients, while the behavioral disturbances were more marked in school-age children.

We report 3 cases of posterior fossa subdural effusion resulting from head trauma, and we review 20 previously reported cases. All patients with the acute type presented with progressive deterioration of consciousness associated with stiff neck, seizure, and dyspnea (apnea). By contrast, in the subacute or chronic type, persistent headache, multiple cranial nerve pareses, and ataxia were characteristic. Occipital bone fracture was common in the acute type, and supratentorial subdural effusion was more frequently associated with the subacute or chronic type. Evacuation of the subdural fluid collection through a burr hole is the most common and effective treatment, but subdural-peritoneal shunting or closed drainage of the subdural fluid collection may be necessary. The prognosis of posterior fossa subdural effusion after head trauma is relatively good.
