Cerebral atrophy following ACTH therapy.

In a study of 15 patients with infantile spasms and Lennox syndrome 4 (26.7%) showed no cerebral atrophy and 11 (73.3%) showed mild ventricular and sulcal enlargement before ACTH therapy. Ventricular and sulcal enlargement increased soon after ACTH therapy in most patients. Cerebral atrophy was reversible at over 1 month after ACTH therapy. However, in three instances, cerebral atrophy was not reversible, and one patient with infantile spasms had chronic subdural effusion, which appeared to be a complication of treatment with ACTH. Patients on ACTH therapy should be carefully monitored.

Neurosurgical aspects of cerebral cryptococcosis.

Eleven patients with raised intracranial pressure caused by cerebral cryptococcosis developed complications requiring neurosurgical operations. Two patients were fully conscious on admission, and 9 had impaired consciousness, four of whom were comatose. Seven patients were found to have hydrocephalus only. Two patients had cerebral edema initially, and 2 had cystic lesions. One of the latter developed subdural effusion. All patients eventually developed progressive hydrocephalus requiring placement of a ventriculoperitoneal shunt. Four patients were initially treated by external ventricular drainage. When external ventricular drainage was used initially, there were no associated complications; however, there was a high incidence of complications (4 of 7 patients) when a ventriculoperitoneal shunt was placed as the initial treatment. Of the 11 patients, 10 (91%) survived; of these 9 (82%) made an excellent recovery and 7 (64%) returned to their original work. The patient who died had been receiving steroid therapy for hypopituitarism.

Thrombocytosis and thrombocytopenia in childhood bacterial meningitis.

To assess factors affecting the development of reactive thrombocytosis during bacterial meningitis, thrombocyte counts of 311 children with cerebrospinal fluid culture-positive bacterial meningitis were followed during hospitalization. Thrombocytosis (platelet counts greater than 500 x 10(9)/liter) was seen in 49% of the patients after the first week of treatment. Thrombocyte counts were higher in infants and in patients with long duration of illness before admission. Subdural effusion and cephalosporin therapy were associated with more pronounced thrombocytosis We found no relation between thrombocytosis and neurologic complications, but the patients who died developed thrombocytopenia instead of thrombocytosis. The difference between the thrombocyte curves of the surviving and dying patients might be utilized in predicting the final outcome in the severest cases of bacterial meningitis. We speculate that inflammatory cytokines, especially interleukin 1-beta, induce reactive thrombocytosis in bacterial meningitis.

Haemophilus influenzae meningitis. A comparison between chloramphenicol and ampicillin therapy with special reference to impaired hearing.

131 patients suffering from meningitis due to Haemophilus influenzae or parainfluenzae were re-examined after 1-15 years, using hospital records, questionnaires, and audiological examination, especially to compare chloramphenicol and ampicillin therapy. Mortality was 3.8%. Subdural effusions occurred in 14.5% of cases uni- or bilaterally. There was deafness in 2.3%, and moderate hearing loss in 8.4%. Convulsions appeared later in 6.9%. The final outcome was good in 60%. The most important factors in prognosis seemed to be the severity of the symptoms and the condition of the patient on admission to hospital. No clear difference was seen between the results of chloramphenicol and ampicillin therapy, but total loss of vestibular function was found in 3 cases in the ampicillin group, and in none in the chloramphenicol group. In mortality and deafness, the differences in outcome were similar, although not statistically significant. As these observations show, the therapy used in Haemophilus influenzae meningitis needs re-evaluation.

Micturitional disturbance in herpetic brainstem encephalitis; contribution of the pontine micturition centre.

Micturitional disturbance is rarely mentioned in human herpetic brainstem encephalitis although the pontine tegmentum, called the pontine micturition centre, seems to regulate the lower urinary tract in experimental animals. The case of a 45 year old man, who developed subacute coma and hiccup-like dysrhythmic breathing, and needed assisted ventilation is reported. Examination of CSF showed mononuclear pleocytosis and antibody against herpes simplex virus type 1, but the opening pressure was 90 cm H2O. Brain CT showed brain swelling, predominantly in the posterior fossa, and bilateral subdural effusion. Herpetic brainstem encephalitis was diagnosed, and he received 900 mg/day vidarabine. On regaining consciousness, he had left trochlear nerve palsy, left corectopia, ageusia, and urinary retention. Brain MRI showed right side dominant, bilateral pontine segmental lesions extending slightly to the midbrain and medulla. After two weeks he was able to urinate but showed nocturnal urinary frequency, urinary incontinence, and voiding difficulty. Urodynamic studies showed a residual urine volume of 350 ml and detrusor hyporeflexia on voiding. Micturitional disturbance gradually disappeared together with the neurological signs. The bilateral pontine tegmental lesions in this patient are similar to those in previous findings on brainstem strokes, evidence of the presence of a pontine micturition centre in humans.

Duplex pulsed Doppler US versus intracranial pressure in the neonate: clinical and experimental studies.

This study was conducted to determine if the resistive index (RI) could be used for the examination and follow-up of neonates with increased intracranial pressure. First, in a laboratory model with four mongrel dogs, RI was found to correlate linearly with cerebral perfusion pressure. Second, RI was studied in 57 healthy neonates and 285 neonates with abnormal clinical or head ultrasound findings. Average RI for healthy newborns was 75 +/- 10 and was inversely related to gestational age. RI in newborns with abnormal findings was uniformly elevated, but these values varied considerably and were not statistically different from normal values. Third, the RI was found to decrease significantly after patent ductus arteriosus ligation, tapping of subdural effusions, ventricular tapping (later cerebrospinal fluid shunting led to a further drop in RI), and ventriculoperitoneal shunting. Elevated RI indicates possible intra- or extracranial abnormality affecting cerebral blood flow. Doppler RI is valuable in following up neonates with abnormal or unstable conditions and in assessing the effectiveness of therapies to improve cerebral perfusion.

The clinical, radiological and surgical aspects of cerebral hydatid cysts in children.

A series of 13 pediatric patients underwent surgery for cerebral hydatid cysts at the Department of Pediatric Neurosurgery between 1993 and 2003. Headache and motor weakness were the main initial signs of these patients. A round cystic lesion was the characteristic appearance on computed tomography of each patient. Different cyst locations such as the liver, kidney or spleen were detected in 5 patients. Surgery using Dowling's technique was performed in all patients as the main treatment. Intraoperative rupture and cyst recurrence were observed in only 1 patient. Subdural effusion, intraparenchymal air and hemorrhage were the main complications observed after surgery. None of the patients died after surgery. Because of its efficacy combined with excellent results, surgery is currently the method of choice in the treatment of cerebral hydatid cyst in children.

A case of Sotos syndrome with subduroperitoneal shunt.

The authors present a case of Sotos syndrome with increasing severity of subdural hygroma from the age of 5 months, which was managed with a subduroperitoneal shunt at 10 months of age. The patient had been followed up until 30 months of age with continuing improvement of symptoms. The patient initially presented with dolichocephaly accompanied by macrocrania, early tooth development, repeated pneumonia infections and developmental retardation concerning crawling, sitting, walking and speaking at 5 months of age. Magnetic resonance imaging (MRI) demonstrated partial hypoplasia of the corpus callosum and bifrontal subdural hygroma. The patient underwent subduroperitoneal shunting at 10 months of age with partial improvement of symptoms. At 18 months of age, the patient showed increased irritability and sweating, and development of spinal kyphosis, which resulted from shunt malfunction as shown in the shuntogram. The appearance of cervical syringomyelia was also seen in the MRI. After shunt revision, the irritability, sweating and kyphosis improved along with disappearance of the syringomyelia. The authors describe a case of Sotos syndrome with subduroperitoneal shunt that showed syringomyelia which developed with shunt malfunction but disappeared after shunt revision. We emphasize the importance of active management such as subduroperitoneal shunting to drain the cerebrospinal fluid in the Sotos syndrome.

Computer tomographic long-time results after surgical removal of subdural fluid collections in infancy and childhood.

61 infants and children underwent surgery of acute hygroma, acute subdural hematoma, chronic subdural hygroma, chronic subdural hematoma, and subdural empyema. Long time-follow up including computerized tomography could be performed in 20 of these cases. Only 3 CT-scans had been without pathological finding. The most common finding had been an enlargement of the inner and outer CSF spaces suggesting cerebral atrophy. No correlation had been found to kind of surgical treatment and clinical status.

Third ventricle choroid plexus papillomas.

Choroid plexus papillomas are only infrequently located in the third ventricle. Two infants with such lesions are presented and the diagnosis by computed tomography described. The transcallosal approach to the third ventricle was employed in both cases and led to successful excision. This approach is recommended for lesions in the anterior third ventricle in children, and the occurrence of subdural effusions as a complication is pointed out.

Aztreonam in the treatment of bacterial meningitis.

The monobactam aztreonam was used to treat 22 young patients with meningitis caused by gram-negative bacilli. Haemophilus influenzae was isolated from the CSF of 21 patients and Salmonella heidelberg from the CSF of 1. Dosages ranged from 100 to 200 mg/kg/day in 4 doses at 6-hour intervals. Minimal inhibitory concentrations were determined by the broth dilution method for all isolated strains, and values ranged from 0.05 to 2.0 micrograms/ml. Blood and CSF drug levels were determined by a microbiologic plate diffusion method, and mean values for CSF and blood were 1.4 and 14.9 micrograms/ml, respectively. The outcome was good in 21 patients; 1 patient died. Complications were mild; subdural effusion occurred in 6 cases and was managed clinically; asymptomatic hydrocephalus was seen in 4; seizure during the acute phase occurred in 6 cases; hypoacusis was noted in 2, and motor impairment was detected at the follow-up in 1 case. Aztreonam achieved good blood and CSF penetration and performed well in the treatment of 20 cases of H. influenzae meningitis and in the one case of S. heidelberg meningitis.

Some important pitfalls in the diagnosis and treatment of bacterial meningitis in children.

Some of the common errors and problems of the physician who cares for the child with bacterial meningitis are: 1) misdiagnosis; 2) inappropriate handling of cerebrospinal fluid; 3) inadequate assessment of therapeutic responses; 4) inappropriate drug therapy; 5) improper treatment of seizures; 6) inadequate care of increased intracranial pressure; 7) inappropriate evaluation of persistent fever; 8) inappropriate fluid therapy; 9) inadequate investigation of persistent neurologic deficit; 10) overvigorous treatment of subdural effusion; 11) inadequate assessment of neurologic or psychologic impairment; and 12) inadequate consideration of possible underlying defects.

Neonatal lead poisoning. An unusual clinical manifestation.

A case of lead encephalopathy in a 2-month-old child is reported. Modes of poisoning are discussed and the unusual clinical manifestations of metallic brownish discoloration of nails and subdural effusion are presented. The possibility of lead poisoning as a cause of convulsions in neonates should be considered by doctors caring for these patients. Detailed history of lead exposure in prenatal and postnatal periods aids in early diagnosis and treatment which, thus, prevent severe neurological sequelae.

Cerebral infarction in Hemophilus influenzae type B meningitis.

Over a 5-year period, 8 (4.7%) of the 170 children diagnosed at Milwaukee Children's Hospital as having Hemophilus influenzae type b (HITB) meningitis developed cerebral infarction. Compared with children who did not develop infarcts or with children who developed other neurologic complications, such as subdural effusion, empyema, or meningoencephalitis, these children had significantly higher cerebrospinal fluid (CSF) leukocyte counts on initial lumbar puncture and had a greater likelihood of seizure activity. In seven of eight patients with cerebral infarction, a focal or generalized seizure heralded neurologic findings associated with abnormal radiographic studies. Two of the eight patients died, and two were permanently severely damaged. In the other four patients, there was eventual recovery from gross neurologic deficits. The mortality in patients with HITB meningitis complicated by cerebral infarction (25%) was significantly greater than that in other patients with HITB meningitis (0.6%). The pathophysiology of infarction in patients with bacterial meningitis is uncertain but may in part relate to arteriospasm. Cerebral infarction is a serious, and in the present experience, not uncommon complication of H. influenzae meningitis.

Macrocephaly is not always due to hydrocephalus.

Macrocephaly is a clinical symptom with a heterogeneous cause. Besides enlarged ventricles (hydrocephalus) it can be caused by increased brain volume, expanded extracerebral spaces, intracranial cysts, and dilated vessels. Drawing on the experience of more than 8 years using transfontanellar sonography including Doppler techniques, some typical clinical and sonographic features of several forms of macrocephaly are addressed. Besides isolated familial or sporadic megalencephaly, extracerebral fluid collections are the main explanation of macrocephaly. Subdural effusions with compression of the brain by increased intracranial pressure should be differentiated from craniocerebral disproportion without increased intracranial pressure. Subependymal and subarachnoidal cysts may cause extraodinary displacements and compression of brain structures; nevertheless, the prognosis is rather optimistic, for the brain structure itself is generally not destroyed. In some infants with complex genetic, neurocutaneous, and neurometabolic syndromes, macrocephaly is an early clinical sign. The outcome in these infants is very different and dependent on the dysfunction of the brain by the specific disease (eg, storage of neurotoxic substances, dysplasia, gliosis, vascular disturbances, or brain tumors). In infants with vascular malformations the diagnosis can be established more exactly by using Doppler techniques. I recommend some practical diagnostic procedures in cases of macrocephaly. Nevertheless, in many patients with increased head size an exact statement about the further prognosis cannot be established by one examination; therefore, a developmental evaluation in combination with regular sonographic evaluation is the most valuable method in taking care of all infants with macrocephaly.

The role of endoscopic choroid plexus coagulation in the management of hydrocephalus.

Endoscopic choroid plexus coagulation has been used for the treatment of hydrocephalus at this unit for the past 20 years, and 156 operations have been performed on 116 patients. These patients were analyzed retrospectively to determine the rate of long-term clinical control of hydrocephalus, factors associated with successful control, change in ventricular size after surgery, and rate of surgical complications. Data were found for 104 patients with a median age at surgery of 5 months (range, 1 wk-30 yr) and a mean follow-up of 10.5 years. Control of hydrocephalus by choroid plexus coagulation was found to be best in children with communicating hydrocephalus and a slow to moderate rate of increase in head circumference (18 of 28, 64% long-term control), whereas those who presented with tense fontanels and rapidly progressive hydrocephalus had the lowest rate of success. Overall, 36 of 104 (35%) achieved long-term control without cerebrospinal fluid shunts. The ventricular size was not significantly reduced by choroid plexus coagulation (ventricular index before and after surgery, 0.64 and 0.58, respectively; P = 0.13), although sulcal markings became more prominent in all successfully treated patients, indicating reduced intracranial pressure. There were no deaths resulting from surgery, and serious morbidity was low. Eight patients developed infections (five meningitis and three implant infections). Other complications included postoperative fits (two patients), respiratory arrest in a premature infant (one patient), low-pressure state (one patient), ventricular drain displacement or blockage (eight patients), subdural effusion (one patient), and intraoperative minor ventricular bleeding, forcing abandonment of the procedure (two patients).(ABSTRACT TRUNCATED AT 250 WORDS)
