Forty-four cases of meningococcal meningitis in children at one hospital between 1971 and 1975 inclusive were studied to document the course and complications of this disease in children in the current therapeutic era. The mortality was 5%. Of the 41 survivors 76% were healthy 1 to 5 years after the episode of meningitis. Permanent severe sequelae (facial palsy, optic atrophy and ptosis) were seen in three (7%) of the survivors, and mild hearing loss, hyperactivity and nervousness were noted in seven (17%). Electroencephalography was not useful in determining management or prognosis. Both the mortality and the frequency of early and late complications among the survivors were lower than those reported from earlier studies. 相似文献

A variety of associated lesions may require the neurosurgeon''s assistance in the management of bacterial meningitis. As treatment of this infection of the central nervous system proceeds, the surgeon will have to decide about the concurrent or subsequent operative treatment of congenital dysraphic states, paraneural infections, compound fractures or penetrating wounds of thecranium or spine, or infected bypass shunts for cerebrospinal fluid (CSF). In patients with intractable meningitic infections the surgeon may have to insert a ventricular drainage-irrigation system to permit adequate perfusion of the CSF pathways with antibiotic. Hydrocephalus or subdural effusions complicating meningitis may bring the patient to the surgeon long after the infection has been cured. This paper examines these problems and outlines the current principles of management. 相似文献

Background
Bacterial meningitis is often associated with cerebral compromise which may be responsible for neurological sequelae in nearly half of the survivors. Little is known about the mechanisms of CNS involvement in bacterial meningitis. Several studies have provided substantial evidence for the key role of nitric oxide (NO) and reactive oxygen species in the complex pathophysiology of bacterial meningitis. 相似文献10.

We studied cerebral blood flow (CBF) autoregulation and intracranial pressure (ICP) during normo- and hyperventilation in a rat model of Streptococcus pneumoniae meningitis. Meningitis was induced by intracisternal injection of S. pneumoniae. Mean arterial blood pressure (MAP), ICP, cerebral perfusion pressure (CPP, defined as MAP - ICP), and laser-Doppler CBF were measured in anesthetized infected rats (n = 30) and saline-inoculated controls (n = 30). CPP was either incrementally reduced by controlled hemorrhage or increased by intravenous norepinephrine infusion. Twelve hours postinoculation, rats were studied solely during normocapnia, whereas rats studied after 24 h were exposed to either normocapnia or to acute hypocapnia. In infected rats compared with control rats, ICP was unchanged at 12 h but increased at 24 h postinoculation (not significant and P < 0.01, respectively); hypocapnia did not lower ICP compared with normocapnia. Twelve hours postinoculation, CBF autoregulation was lost in all infected rats but preserved in all control rats (P < 0.01). Twenty-four hours after inoculation, 10% of infected rats had preserved CBF autoregulation during normocapnia compared with 80% of control rats (P < 0.01). In contrast, 60% of the infected rats and 100% of the control rats showed an intact CBF autoregulation during hypocapnia (P < 0.05 for the comparison of infected rats at normocapnia vs. hypocapnia). In conclusion, CBF autoregulation is lost both at 12 and at 24 h after intracisternal inoculation of S. pneumoniae in rats. Impairment of CBF autoregulation precedes the increase in ICP, and acute hypocapnia may restore autoregulation without changing the ICP. 相似文献

Several different sources of data, including statutory notifications, were used to identify cases of acute bacterial meningitis in childhood in a defined population. Only half the cases of meningococcal meningitis and less than one quarter of ofther types of bacterial meningitis had been notified. Notified cases differed from the remainder with respect to causative organism, age, outcome, and type of hospital of admission. Thus notifications are an unreliable measure of incidence for this disease, and studies of infectious disease based on notified cases alone should be interpreted with considerable reserve. It is suggested that infectious-disease surveillance should be both clinical and microbiological and that data from different sources need to co-ordinated. The reason for reporting each disease (or organism) should be specified and and reviewed periodically. 相似文献

The results of the laboratory examination of 2034 patients with meningococcal infection and purulent meningitides, hospitalized during the period of June 1980 to October 1983, revealed that three main etiological agents were responsible for these diseases: meningococci, pneumococci and Haemophilus influenzae. The susceptibility of the patients to different etiological agents was found to depend on their age. Children aged up to 3 years constituted 75% of the patients with meningitis caused by H. influenzae; 50% of the patients with meningococcal infection were children aged up to 5 years; pneumococcal meningitis occurred more frequently in adults. Serogroup A meningococci were found to prevail in patients with meningococcal infection. Besides, in children serogroup C meningococci could be isolated in 24% of cases. Since 1983 the cases of the isolation of strains belonging to serogroup B increased in number. Among the pneumococci responsible for the disease serotypes 1, 19, 6 and in children serotype 12 occurred most frequently. 相似文献
