1/94. Fatal serratia marcescens meningitis and myocarditis in a patient with an indwelling urinary catheter.serratia marcescens is commonly isolated from the urine of patients with an indwelling urinary catheter and in the absence of symptoms is often regarded as a contaminant. A case of fatal serratia marcescens septicaemia with meningitis, brain abscesses, and myocarditis discovered at necropsy is described. The patient was an 83 year old man with an indwelling urinary catheter who suffered from several chronic medical conditions and from whose urine serratia marcescens was isolated at the time of catheterisation. serratia marcescens can be a virulent pathogen in particular groups of patients and when assessing its significance in catheter urine specimens, consideration should be given to recognised risk factors such as old age, previous antibiotic treatment, and underlying chronic or debilitating disease, even in the absence of clinical symptoms.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/94. Recurrent subdural haematoma as the primary and sole manifestation of chronic lymphocytic leukaemia.An 81-year-old man with a recurrent subdural haematoma as the first and only manifestation of chronic lymphocytic leukaemia (CLL) is described. Microscopic examination of the encapsulated haematoma showed leukaemic infiltration and the diagnosis was confirmed by bone marrow aspiration and by pathological examination of the brain at autopsy.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
3/94. acinetobacter meningitis: four nosocomial cases.We report the clinical features and therapeutic outcomes of four patients with multiantibiotic-resistant acinetobacter meningitis. There were three males and one female, aged from 17 to 49 years. Three of them had suffered from head injuries with skull fractures, and the other suffered from an intracerebral hemorrhage and underwent a craniotomy. All four patients acquired nosocomial acinetobacter meningitis, and multiantibiotic resistance developed. After treatment with imipenem/cilastatin, three of the four patients survived; one died of multiorgan failure. Because the clinical manifestations of acinetobacter meningitis are similar to those of other gram-negative bacillary meningitis, the diagnosis can only be confirmed by bacterial culture. Resistance to multiple antibiotics, including third-generation cephalosporins, is frequently seen in patients with nosocomial acinetobacter meningitis, and imipenem/cilastatin seems to be the antibiotic of choice for this potentially fatal central nervous system infection.- - - - - - - - - - ranking = 9.2770131315276keywords = central nervous system, nervous system (Clic here for more details about this article) |
4/94. Non-typhoid salmonella meningitis complicated by a infarction of basal ganglia.A previously healthy 16-month-old Korean girl with symptoms of fever, vomiting, and generalized tonic seizure was diagnosed to have Group D non-typhoid salmonella meningitis. The patient was treated with ceftriaxone (100 mg/kg/day) and amikin (22.5 mg/kg/day) initially and ciprofloxacin (30 mg/kg/day) was added later because of clinical deterioration and disseminated intravascular coagulation. brain CT performed on the second day showed a well-demarcated low density lesion in the right lentiform nucleus and both caudate nuclei, without evidence of increased intracranial pressure. MRI performed on the 11th day confirmed CT scan findings as well as right subdural fluid collection, brain atrophy, and ventriculomegaly. She underwent subdural drainage and later ventriculo-peritoneal shunt operation. Despite receiving intensive treatment, she still has severe neurologic sequelae. Our case shows that infarctions of basal ganglia and thalami are not specific for tuberculous meningitis and that meningitis complicated by infarction is indicative of grave prognosis.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
5/94. nocardia asteroides pneumonia, subcutaneous abscess and meningitis in a patient with advanced malignant lymphoma: successful treatment based on in vitro antimicrobial susceptibility.nocardia asteroides pneumonia, subcutaneous abscess and meningitis without brain abscesses developed in a patient with advanced non-Hodgkin's lymphoma, who had received corticosteroid therapy and cancer chemotherapy for a long time. At the time of nocardial pneumonia, profound lymphocytopenia and hypogammaglobulinemia was seen. The severely immunosuppressed condition most likely accounted for the uncommon infection, nocardiosis. The organism isolated from the sputum, subcutaneous abscess and cerebrospinal fluid was strongly resistant to cotrimoxazole, which is the recommended standard treatment, but it was susceptible to imipenem (IPM) and erythromycin (EM) in an in vitro antimicrobial susceptibility study. The patient's nocardiosis responded well to chemotherapy including IPM and EM.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
6/94. Infectious meningitis mimicking recurrent medulloblastoma on magnetic resonance imaging. Case report.This report and the accompanying review of the literature address the challenges, when using surveillance magnetic resonance (MR) imaging, of establishing the origin of newly detected central nervous system lesions. Routine surveillance MR imaging in a 16-year-old boy, whose medulloblastoma had been successfully treated, demonstrated asymptomatic nodular leptomeningeal enhancement of the brain and spinal cord, which was consistent with recurrent disease. Examination of the cerebrospinal fluid, however, led to the diagnosis of bacterial meningitis. Two weeks after completion of antibiotic therapy, the original MR imaging findings were seen to have resolved. This case illustrates the importance of considering clinical and laboratory data, including results from a complete examination of the cerebrospinal fluid, when interpreting the origin of new lesions revealed by MR imaging.- - - - - - - - - - ranking = 10.277013131528keywords = central nervous system, nervous system, brain (Clic here for more details about this article) |
7/94. Clinical manifestations of bacillus cereus meningitis in newborn infants.bacillus cereus (B. cereus) meningitis sometimes occurs in patients with risk factors, which are associated with central nervous system (CNS) anomalies, surgical or anaesthetic access to CNS. We observed two cases of B. cereus meningitis in neonates without such risk factors. The clinical courses of both neonates were fulminant, and routine antibiotic therapy failed. Intracranial haemorrhage was evident at autopsy. According to the previous neonatal case reports and our experience, we found that six of seven neonates were premature babies admitted to the neonatal intensive care unit, five died within a week of onset of the disease, and six had intracranial haemorrhage. We speculate that B. cereus meningitis may occur in neonates, even without any of the risk factors previously described in adult case reports, and that the clinical manifestations of the meningitis might be characterized by the high incidence of intracranial haemorrhage and poor mortality.- - - - - - - - - - ranking = 9.2770131315276keywords = central nervous system, nervous system (Clic here for more details about this article) |
8/94. bacteremia, meningitis, and brain abscesses in a hospitalized infant: complications of pseudomonas aeruginosa conjunctivitis.This report describes a preterm infant hospitalized in a neonatal intensive care unit who developed pseudomonas aeruginosa conjunctivitis associated with bacteremia, meningitis, and multiple brain abscesses. P. aeruginosa conjunctivitis can rapidly progress to an invasive eye infection, such as corneal ulceration or endophthalmitis, leading to poor vision or blindness. Progression of this infection may lead to systemic disease. However, as illustrated in this report, P. aeruginosa conjunctivitis may be associated with the development of systemic complications such as bacteremia and meningitis in the absence of invasive eye disease. P. aeruginosa is a relatively common cause of conjunctivitis in hospitalized preterm and low birth weight infants. Given the severity of the ocular and systemic complications of Pseudomonas conjunctivitis, clinicians are reminded that prompt detection and treatment of neonatal conjunctivitis is critical.- - - - - - - - - - ranking = 5keywords = brain (Clic here for more details about this article) |
9/94. adult citrobacter freundii meningitis: case report.Citrobacter is a distinct group of Gram-negative bacilli belonging to the enterobacteriaceae family. central nervous system (CNS) infections due to Citrobacter are uncommon, though they occur more frequently in neonates and young children. In adults, Citrobacter meningitis is extremely unusual with only 6 cases reported in the literature before 1998. This rare CNS infection has been seen in patients with head trauma, following neurosurgical procedures, and in those who are immunocompromised. Of the patients in the 6 reported cases, only one developed multi-antibiotic resistant Citrobacter CNS infection. Adding to this small number of reported cases, we report an adult case of post-neurosurgical meningitis and subdural empyema caused by multi-antibiotic resistant citrobacter freundii and also review the literature related to this infection. Antimicrobial therapy with imipenem and third-generation cephalosporins failed to result in cerebrospinal fluid sterilization in our patient. Because of the use of broad-spectrum antibiotics, multi-antibiotic resistant Citrobacter species have developed in this nosocomial CNS infection and now present a therapeutic challenge. Therefore, further clinical studies are needed to determine updated therapeutic modalities for treating this life-threatening infection.- - - - - - - - - - ranking = 2.1672252024597keywords = nervous system (Clic here for more details about this article) |
