Twelve fatal cases of encephalopathy associated with sepsis were examined in a ten-year retrospective study. The sources of infection and organisms isolated were variable. Six of the patients had focal neurologic signs; five had seizures. The level of consciousness varied from drowsiness to deep coma, and electroencephalograms revealed diffuse or multifocal abnormalities. Computed tomographic head scans and cerebrospinal fluid examinations were usually unremarkable. Eight patients had disseminated microabscesses in the brain at autopsy. Four patients had proliferation of astrocytes and microglia in the cerebral cortex, a feature associated with metabolic encephalopathies. Additional findings included cerebral infarcts, brain purpura, multiple small white matter hemorrhages, and central pontine myelinolysis. Although sepsis may cause encephalopathy by producing disturbances in cerebral synaptic transmission and cerebral energy production through a toxic mechanism, bacterial invasion of the brain with the formation of disseminated microabscesses is also an important cause.

Bacterial infections are frequent events in premature and newborn infants. The reason is a defective specific and nonspecific defence of bacterial organisms. Some immunoglobulins like IgM and IgA including secretory IgA are absent. Premature infants also show a decreased level of IgG. Cellular immunity is anatomically intact but functionally defective. A number of complement factors are lacking, the activation of the alternative pathway is impaired. Newborn infants with perinatal problems like asphyxia or difficult delivery, show defects of leucocyte function like decreased deformability, defective chemotaxis and defective killing of ingested bacteria. Certain diseases, like hypoxia and malformations of immature organ functions in this age group (decreased acid production in the stomach), facilitate bacterial colonization of surface epithelia and the invasion of tissues. Consequences of these pathogenetic mechanisms are an unimpaired propagation of bacterial organisms into the blood and meninges without localization of the infecting organisms at the entry site. Bacterial meningitis is not considered a separate disease entity but a complication of bacteremia and sepsis. Clinical symptoms are nonspecific at the onset of the infection. Fever is frequently absent; decreased appetite, vomiting, a bloated abdomen, diarrhea, tachycardia, tachypnea are early signs of a bacterial infection, a grey mottled appearance, cyanosis, jaundice, petechiae, apneic spells, seizure activity and a metabolic acidosis are symptoms of advanced infection. Successful treatment at this stage is often not possible. Every sign of a decreased well being of a newborn of premature infant warrants laboratory and bacteriologic work up for septicemia.(ABSTRACT TRUNCATED AT 250 WORDS)

A survey of 89 patients with subdural empyema was conducted to assess the incidence of late seizures and morbidity in this disease. Twenty-four patients died during the acute stage of the illness and, of the 65 survivors, 13 were lost or had incomplete follow-up review. Hemiparesis occurred in 48 of the survivors during the acute stage, and all but nine recovered completely. Thirteen patients had a visual field deficit and all recovered; in three of these 13 who had speech disorders the deficits persisted. Recovery from neurological morbidity was not related to the type of surgical treatment; however, the mortality rate was improved by craniotomy. The same incidence of early seizures occurred in those who died (62%) as in those who survived (63%). Of those who had no early seizures, 42% had late seizures, the majority appearing within 16 months. Of those who had early seizures, 71% did not have subsequent attacks. The highest incidence of seizures occurred in patients who had their empyema in the second and third decades of life. The incidence of late seizures was not influenced by the method of surgical treatment, the degree of deterioration of consciousness during the acute stage of the illness, nor by occurrence of early seizures. A significantly increased incidence of early seizures was associated with paranasal sepsis, but not with late seizures.

Clinical records of 181 children, aged between one month and seven years, admitted in a four year period, from 1978 through 1982, with the diagnosis of bacterial meningitis are revised. Peak incidence occurred in the age group between six months and three years, and during the months of January to May. N. meningitidis (35%), pneumococcus (4.9%) and H. influenzae (2.7%) were the most frequently isolated bacteria. CSF culture was negative in 56% of the children. All of them had previously taken antibiotics. Complications were present in 6.4%, with highest incidence in the known-agent group, on the following order: septic shock, 11%, seizures, 6.6%, and subdural effusion, 2.2%. Permanent sequelae were present in 3.8%, being deafness predominant. Twelve (6.3%) out of the 181 died, and death was result of fulminant meningococcal sepsis with endotoxic shock in ten of these patients. Clinical and psychological followed-up of twenty-nine children with isolated causal agent, were compared with a control group, finding no statistically-significant difference.

There is a type of cerebral lesion, which kills neuronal cells at a later stage (greater than 48 hrs) post CA, while the systemic circulation is functioning normally. Although this lesion is probably dependent on multiple factors (----multiple therapies), a keyfactor in the pathogenesis is the loss of autoregulation and "finetuning" of the cerebral bloodflow according to local tissue metabolic needs. Although beneficial effect of almost none of the following therapies has been documented in randomised clinical studies, the following suggestions are made: a) In the CA-CPR phase: efficient respiratory care and external cardiac compressions (ECC), especially during bicarbonate administration; consider open chest CPR early, especially in cases of long arrest time and ineffective ECC. The socalled new CPR does not improve neurological outcome. b) In the post CPR phase: The non-autoregulated brain (cfr. focal ischemia) is kept preferentially at pCO2 values 25-30 mmHg, pO2 values greater than 100 mmHg, and normotension. Some form of stress, seizure and hyperthermia control prevents further imbalance metabolism/bloodflow. Relative dehydration, oncotic balance, steroids, early control of sepsis and uremia, early CT scan and measurement/control of ICP. All the above is currently grouped under "standard neuro-intensive therapy". Some other therapies, presently suggested by animal research are not very obvious, need first randomised clinical studies and are not suggested at this stage for clinical use: barbiturate coma, diphantoine, streptokinase, multifaceted therapy including hemodilution-brainflushing, Ca++ influx blocking drugs (lidoflazine). One such "innovative" therapy, barbiturate coma, has already been proven to be relatively ineffective (BRCT I) (Acta anaesth. belg., 1984, 25, suppl., 219-226).

The purpose of this work was to review the literature about the newborn neurological pathology and to compare it with our results starting from the observation of 650 children who born at the Clinical Hospital of Porto Alegre from September 1979 to June 1980. Out of these, 100 presented with neonatal neurological pathology. These newborn were studied as to the age of the mother at the birth time, Apgar rate, weight and cephalic perimeter at the birth time, probable etiologies, and clinical picture and evolution. These newborn were compared to control groups and the results were discussed on the grounds of literature. Out of 100 newborn with neurological pathology, 65% presented with pathological neurological examination and 35% with normal neurological examination. The 65 newborn with pathological neurological examination had hypotonia, decreased deep tendon reflexes, decreased or absence of superficial reflexes in 40 cases. Hyperactivity, hypertonia and tremors were observed in 25 cases. Coma was present in 6 of these newborn with apathy and hypotonia. Seizures were present in 41 cases. EEG was performed in 29 of these 41 cases in the first five days of life. The EEG was normal in 15 (51.7%) newborn and it was pathologic in 14 (48.3%) newborn. The 100 newborn had the following diagnosis: 37 birth anoxia, 13 hemorrhages, 24 meningitis, 14 metabolic seizures, 4 sepsis, 1 kernicterus, 2 chromosomopathies, 3 malformation, 1 cerebral palsy, and 1 congenital rubeola. Out of the 37 newborn with birth anoxia, 20 (54.1%) had a good evolution, 7 (18.9%) had sequela and 10 (27.0%) died. Out of 13 newborn with hemorrhages 2 (15.4%) had a good evolution, 5 (38.5%) had sequela, and 6 (46.1%) died. Out of 24 newborn with meningitis, 18 (75.0%) had a good evolution, 5 (20.8%) had sequela, and 1 (4.2%) died. Out of 58 newborn with a good evolution, 30 had normal newborn neurological exam, and 28 had transient alterations. Out of 23 newborn who presented with sequela later on, only 5 had normal newborn neurological exam. All the 19 who died, had pathological newborn neurological exam.

Cerebral venous thrombosis occurring in puerperium is about 10 to 12 times more frequent in India than in Western countries. A clinical study of 135 patients with cerebrovascular accidents in early puerperium is reported. Cortical vein thrombosis is common and arterial thrombosis rare (6/135). The illness usually occurs within the first two weeks, after normal delivery at full term, in a multiparous woman, with multi-focal seizures, stupor or coma, regressing focal signs or at times as pseudotumour cerebri. Deep leg vein thrombosis and pelvic sepsis are rare. Mortality has been high reaching 28 to 33 percent in both Indian and Western countries. With the use of anticoagulants in some selected patients and earlier; energetic, supportive and symptomatic measures in others the mortality could be reduced to less than 20 percent. The quality of survival is good since those who survive have only minimal physical disability.

A prospective study of infants weighing less than 800 g at birth and cared for in a single neonatal intensive care unit between 1977 and 1980 was conducted. Neonatal mortality was 80%; neurodevelopmental outcome was assessed in 16 of the 18 survivors. Mean birth weight for these 16 was 730 g; mean gestational age was 26 weeks. Perinatal asphyxia, respiratory distress, apnea, mechanical ventilation, and chronic pulmonary disease were commonplace. Symptomatic intracranial hemorrhage, seizures, sepsis, or meningitis did not occur in survivors. Of the 16 infants, 13 (81%), including all three with birth weight less than 700 g, were without major CNS handicaps and were developing appropriately at 6 months to 3 years of age. Only one of the 16 had clearly subnormal mental development. None had a major visual or hearing impairment. Apgar scores at one and five minutes were significantly related to outcome; apnea, mechanical ventilation, and chronic pulmonary disease were not. These data suggest that a remarkably hopeful outcome is possible for the few survivors of extremely low birth weight.

Six infants with disseminated HSV had no mucocutaneous lesions at any time during the course of the illness. These infants presented with lethargy, poor feeding, apnea, acidosis, and hepatomegaly. The diagnosis of HSV was made by culturing the infant's oropharynx and blood, and the maternal cervix. Eight infants with HSV encephalitis had no skin, eye, or mucous membrane lesions. These infants presented with lethargy and low-grade fever, followed within 24 hours by the onset of focal partial motor seizures. The seizures were refractory to anticonvulsant therapy. The mean CSF white cell count was 131 cells/mm3;the glucose and protein concentrations were in the normal range. Brain biopsy was required for the early diagnosis of HSV encephalitis. These 14 cases presented 70% (14/20) of all infants with neonatal HSV diagnosed during the study period. HSV infection should be considered in infants with no mucocutaneous lesions who have signs usually associated with bacterial sepsis or who develop focal seizures during the first three weeks of life.

Hyperosmolality complicating the management of burned patients has multiple etiologies. Sepsis, hyperglycemia, renal failure, electrolyte disturbances, shock, and substances absorbed from the burn wound may be contributing factors. Chemicals, such as propylene glycol, within bacteriostatic topicals may also lead to hyperosmolality. This report describes a patient who developed severe hyperosmolality after 5% Betadine-glycerin therapy for a 60% partial-thickness burn. Status epilepticus developed 36 hours later, and triglycerides were 9,700 mg/dl. After Betadine-glycerin was stopped the central nervous system status slowly improved but pre-seizure function was never regained.
