11/759. Respiratory foreign bodies and eikenella corrodens brain abscess in two children.We report the coexistence of aspirated foreign bodies and brain abscess in two boys. One child had aspirated a metallic needle, and in the other boy partially embedded sunflower seeds were found in the bronchial wall. Both patients had growth of eikenella corrodens (oral gram-negative flora) from the abscess. Aspirated foreign body in the respiratory tract should be one of the diagnostic considerations if any of the normal oropharyngeal organisms such as E. corrodens is the causative organism of brain abscess.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
12/759. incidence of intracranial bullet fragment migration.Migration of retained bullets or bullet fragments may present as a complication of gunshot wounds to the head. This phenomenon has been reported in cases of abscess formation or retained copper fragments. Management of such migratory fragments is controversial. The purpose of this study is to determine the incidence of fragment migration in a population of neurosurgical patients treated for gunshot wounds to the head. Two-hundred and thirteen cases treated at Detroit Receiving Hospital between 1985 and 1987 were reviewed. Each patient treated had initial and one week follow-up imaging studies. Nine cases of documented migratory intracranial bullet fragments were identified. Thus, the incidence in this population is 4.2%. The fragments in eight cases were composed of copper, and in the remaining case, lead. No case was associated with an abscess. Fragments in the anterior fossa were found to migrate towards the sella turcica, while those of the middle fossa and posterior hemispheres migrate towards the confluence of sinuses (Torcula Herophili). Fragment migration was documented as early as 36 h post-injury. Based on this study, we recommend serial imaging studies to look for migrating bullet fragments and surgical removal aided by intra-operative ultrasound to localize the fragment when possible.- - - - - - - - - - ranking = 1.8914629810305E-5keywords = injury (Clic here for more details about this article) |
13/759. Nocardial infection in a renal transplant recipient on tacrolimus and mycophenolate mofetil.Infection with nocardia spp. is an uncommon but important cause of morbidity and mortality in organ transplant recipients. Cotrimoxazole prophylaxis against urinary tract infection and pneumocystis carinii pneumonia in these patients usually prevents nocardial infection also. We report the case of a patient on tacrolimus and mycophenolate mofetil who developed drug-induced diabetes mellitus followed by nocardial brain infection. This infection occurred despite conventional cotrimoxazole prophylaxis. physicians should be aware that newer, more potent and more diabetogenic immunosuppressive regimens may increase the risk of opportunistic infections such as nocardiosis, even in the presence of "adequate" antimicrobial preventive measures.- - - - - - - - - - ranking = 0.16666666666667keywords = brain (Clic here for more details about this article) |
14/759. In vivo proton MR spectroscopy of untreated and treated brain abscesses.MR spectroscopy was performed in three patients with brain abscesses. In two patients, MR spectroscopy revealed end-products of bacterial breakdown (acetate, succinate, amino acids, lactate) in the abscess cysts. In one of these, the spectrum was reversed to a single lactate peak after treatment. In the third patient, MR spectroscopy was performed only after treatment and showed a single nonspecific lactate peak. MR spectroscopy is a potential tool for noninvasive diagnosis of brain abscess and might be useful for evaluating changes after treatment.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
15/759. Group A streptococcal brain abscess.A 48-y-old woman with an acute Group A streptococcal brain abscess is described. The abscess enlarged rapidly with neurological deterioration and required open drainage and excision. The patient was treated with antibiotics for 6 weeks and recovered completely. Group A streptococcus is a rare cause of brain abscess in the antibiotic era and may require urgent neurosurgical intervention.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
16/759. neuroimaging findings of the development and resolution of solitary brainstem abscess: characteristics of neuroimagings in the early stage of brainstem abscess and importance of surgical management for brainstem abscess--case report.A 64-year-old female presented with a solitary brainstem abscess. magnetic resonance imaging and computed tomography demonstrated the development and resolution of the brainstem abscess with an unusual and fluctuating clinical course over several months. Serial neuroimaging examinations are required to detect a brainstem abscess in the early stage to establish the optimum treatment.- - - - - - - - - - ranking = 2.5keywords = brain (Clic here for more details about this article) |
17/759. Fungus-like hyphochytrids associated with human disease.We report two cases, with liver and brain abscess, respectively, where fungus-like organisms belonging to the Hyphochytriomycota were found at the site of inflammation together with peptococcus in the first and cysticercus cellulosae in the second case. This is the first time these groups of organisms have been reported in human material. The role of hyphochytrids in human pathology remained uncertain as they were found together with already known human pathogens.- - - - - - - - - - ranking = 0.16666666666667keywords = brain (Clic here for more details about this article) |
18/759. Brain abscesses associated with pulmonary arteriovenous malformations.We present three patients with brain abscesses who also had pulmonary arteriovenous malformations (AVMs). All patients had hereditary haemorrhagic telangiectasia (Osler's disease). It is probable that the lung AVMs contributed to the development of the brain abscesses by allowing bacteria easier access to the systemic circulation through a right to left pulmonary vascular shunt, bypassing the filtering action of the pulmonary capillaries. In addition, one patient required a period of postoperative ventilation using PEEP, which may have exacerbated the shunt through the lung AVM and led to difficulty in weaning her from the ventilator.- - - - - - - - - - ranking = 0.33333333333333keywords = brain (Clic here for more details about this article) |
19/759. glioblastoma multiforme at the site of metal splinter injury: a coincidence? Case report.The authors report the case of a man who had suffered a penetrating metal splinter injury to the left frontal lobe at 18 years of age. Thirty-seven years later the patient developed a left-sided frontal tumor at the precise site of the meningocerebral scar and posttraumatic defect. Histological examination confirmed a glioblastoma multiforme adjacent to the dural scar and metal splinters. In addition, a chronic abscess from which propionibacterium acnes was isolated was found within the glioma tissue. The temporal and local association of metal splinter injury with chronic abscess, scar formation, and malignant glioma is highly suggestive of a causal relationship between trauma and the development of a malignant brain tumor.- - - - - - - - - - ranking = 0.16678094692136keywords = brain, injury, trauma (Clic here for more details about this article) |
20/759. Successful treatment of brainstem abscess with stereotactic aspiration.BACKGROUND: Brainstem abscess is an uncommon condition associated with a high mortality. We report a case of brainstem abscess in a 51-year-old female with a pulmonary arteriovenous fistula that was cured after appropriate antibiotic therapy following stereotactic aspiration. The value of stereotactic aspiration in the management of brainstem abscess is documented with a review of the relevant literature. CASE REPORT: A 51-year-old female with a pulmonary arteriovenous fistula suffered fever, diplopia and weakness on the right side. Magnetic resonance (MR) imaging of the brain showed a large cystic mass with ring-like enhancement in the brainstem. A diagnosis of brainstem abscess as a complication of pulmonary arteriovenous fistula was made. MR imaging-guided stereotactic exploration was carried out via the suboccipital transcerebellar approach and the pathogen of the brainstem abscess was identified. The brainstem abscess was cured after treatment employing antibiotics to which the pathogen was sensitive. CONCLUSIONS: Stereotactic aspiration is an effective procedure for brainstem abscesses. This procedure is less invasive than open surgery and can be performed even in patients in poor general condition.- - - - - - - - - - ranking = 2keywords = brain (Clic here for more details about this article) |
