1/28. Lithium neurotoxicity.One of the most alarming and potentially serious complications of lithium carbonate therapy is the emergence of central nervous system toxicity. This paper discusses the clinical changes that may occur with illustrative case histories. The role that such factors as serum Lithium levels, sodium balance, organic brain damage, clinical typology, concurrent physical illness and drug interaction play in the genesis of this disorder is discussed. Permanent neurological damage following Lithium poisoning is discussed and guidelines for appropriate use and monitoring of Lithium in psychiatric disorders is outlined.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
2/28. Subpleural lung involvement in Behcet's disease: first localization of a systemic entity.Behcet's disease (BD) is a chronic multisystem vasculitis, affecting many organs and the vascular system, of unknown aetiology. Eyes, skin, joints, the oral cavity, the central nervous system, and, less frequently, heart, lung, kidney, the genital system and the gastrointestinal tract can be involved. Intrathoracic manifestations of BD consist mainly of thromboembolism of the superior vena cava and/or other mediastinal veins; aneurysms of the aorta and pulmonary arteries; pulmonary infarct and haemorrhage; pleural effusion; and, rarely, myocardial and/or hilar lymphoid involvement. In the present case, the patient presented with BD with an asymptomatic subpleural lung mass and bilateral pulmonary artery enlargement. The patient was treated with a combination of surgical and medical therapy with complete resolution of the lung involvement and without any parenchymal relapses after an 8-month follow-up.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
3/28. lymphomatoid granulomatosis in a 4-year-old boy.lymphomatoid granulomatosis is a necrotizing angiocentric and angiodestructive infiltrative process involving primarily the lung, skin, central nervous system, and kidney. The incidence is highest in middle-aged men and is rare in children. We report a case of lymphomatoid granulomatosis involving both skin and lung in a 4-year-old boy. The disease progressed to peripheral T-cell lymphoma, which was unusual in light of recent evidence suggesting a B-cell origin in the majority of cases.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
4/28. Bilateral subpleural ectopic brain tissue in a 23-week-old fetus.Bilateral lesions were seen in the subpleural region in a 23-week-old aborted male fetus. This fetus was not macerated and showed no central nervous system abnormality on physical examination and vertebral magnetic resonance imaging (MRI). Postmortem examination revealed bilateral, paravertebral, subpleural, circumscribed, yellowish-white, fluent lesions 2.5 x 1 x 1 cm in size. These lesions were localized on the upper part of both lungs and there was no other internal malformation. Histological examination of lesions showed adult neurones and well-differentiated neural tissue with white and gray matter, choroid plexus, ependymal structures and, rarely, some peripheral neural cells in addition to immature neuroectodermal cells. These cells were more mature than those in the brain tissue.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
5/28. Treatment of severe pulmonary hemorrhage with activated recombinant factor vii (rFVIIa) in very low birth weight infants.Clinically apparent pulmonary hemorrhage (PH) occurs in 5% to 7% of very low birth weight (VLBW) infants with respiratory distress syndrome (RDS). It is associated with a mortality rate as high as 50% and significant pulmonary and central nervous system morbidities. There is no consensus on treatment modality. We present two VLBW infants with severe PH that did not respond to conventional treatment but were successfully treated with activated recombinant factor vii (rFVIIa). No untoward side effects were noted.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
6/28. infant with severe penicillamine embryopathy born to a woman with Wilson disease.We report a chromosomally normal infant boy with congenital diffuse cutis laxa, severe micrognathia, contractures of all limbs, and central nervous system abnormalities including agenesis of the corpus callosum, born to a woman taking D-penicillamine (DP) for Wilson disease (WD) throughout her pregnancy. His postnatal course was remarkable for chronic lung disease, profound developmental delays, and probable cortical blindness, as well as resolution of his cutis laxa. Embryopathy is a rare complication in babies born to pregnant women treated with DP, and there have been only seven previous reports of birth defects in exposed infants (three of which had favorable postnatal outcomes). The etiology of the severe outcome in this boy is unclear, but prenatal measurement of maternal copper and zinc levels may be indicated for management.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
7/28. Treatment of severe disseminated juvenile systemic xanthogranuloma with multiple lesions in the central nervous system.Juvenile xanthogranuloma (JXG), one of the most common forms of Langerhans-dendritic cell proliferation in young children, usually presents as spontaneously regressing cutaneous lesions. JXG with systemic (extracutaneous) involvement is a rare histiocytic disorder in which significant morbidity and death may occur. The systemic type, especially combined with multiple central nervous system lesions in young children, has a very poor prognosis. The patient described here presented with disseminated disease including lungs, liver, kidneys, ribs, scalp, and central nervous system. The patient was treated with multiagent chemotherapy based on the Langerhans cell histiocytosis II treatment protocol. The regimen used included an additional intrathecal therapy with methotrexate and prednisolone to control central nervous system lesions. The patient was treated for 28 months and has been in remission for almost 5 years.- - - - - - - - - - ranking = 7keywords = central nervous system, nervous system (Clic here for more details about this article) |
8/28. The causes of death in patients with human immunodeficiency virus infection: a clinical and pathologic study with emphasis on the role of pulmonary diseases.The clinical records and autopsy data of 75 patients dying with AIDS were reviewed to determine the frequency of individual diseases diagnosed premortem and postmortem, the significance of pulmonary processes found in the lungs at autopsy, and the clinical and pathologic causes of death. cytomegalovirus (CMV) infection was identified histologically either premortem or postmortem in 81% of patients. The lungs and adrenal glands were infected most commonly. Only one-half of CMV infections were recognized premortem. Pneumocystis pneumonia and Kaposi sarcoma occurred in 68% and 59% of patients, respectively, but were not unsuspected premortem in any patient. Visceral involvement with Kaposi sarcoma, however, was frequently recognized only at autopsy. While disseminated M. avium-intracellulare infection was common (31% of patients), histologically documented pulmonary disease was uncommon (3% of patients). Cryptococcal infection, diagnosed in 10 patients, was confined to the central nervous system in only 1 patient. toxoplasma, in contrast, infected the brain of only 6 patients. All 75 patients had one or more disease processes identified in their lungs or pleurae at autopsy. These processes included opportunistic infections in 76% of patients, neoplasms in 37% (Kaposi sarcoma in 36% and lymphoma in 3%), and other processes in 60%. The most prevalent pathogen, CMV was found in pulmonary tissue from 44 patients and caused significant disease in 21 patients. Five patients died due to CMV pneumonia. pneumocystis carinii was found at autopsy in 24 patients. In spite of treatment, pneumocystis pneumonia was fatal in 11 patients. One patient died with concomitant CMV and pneumocystis pneumonia. Kaposi sarcoma, identified in the lungs of 23 patients, led to death in 5 patients via upper airway obstruction, hemorrhage, or parenchymal destruction. Other fatal pulmonary processes included bacterial pneumonia in 9 patients, idiopathic diffuse alveolar damage in 5, cryptococcosis in 2, and pulmonary hemorrhage in 1. Specific clinical criteria were used to determine the cause of death due to organ system failure. Fifty-one percent of patients died due to respiratory failure; 16% from neurologic disease; 17% from hypotension that was not caused by respiratory, neurologic, or cardiac disease; and 3% from cardiac dysfunction. Thirteen percent of deaths did not meet the clinical criteria defining these 4 categories. This clinical assessment was combined with autopsy data to identify specific diseases as causes of death.(ABSTRACT TRUNCATED AT 400 WORDS)- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
9/28. The use of recombinant activated factor vii in the treatment of massive pulmonary hemorrhage in a preterm infant.Pulmonary hemorrhage is a rare but well-known complication in preterm infants. We present a case of massive pulmonary hemorrhage in a 9-day-old male infant, successfully treated with intravenous recombinant activated factor vii (rFVIIa) (NovoSeven; Novo Nordisk). The infant was diagnosed with sepsis-related disseminated intravascular coagulation and required ventilator support for respiratory distress syndrome and blood transfusions due to active bleeding from endotracheal tube. After administration of the second dose of rFVIIa (120 microg/kg per dose, every 2 h), the active bleeding subsided dramatically and a significant improvement in the oxygenation index was seen 8 h after the third dose of rFVIIa treatment. There were also significant improvements in the prothrombin time, international normalized ratio, activated partial thromboplastin time and plasma fibrinogen levels after the third dose of rFVIIa treatment. The infant was discharged on day 82 of life and there was no finding of thrombosis during the hospitalization period. At month 18 of follow-up, there was no morbidity related to the pulmonary and central nervous systems. This case suggests that rFVIIa is effective as an alternative therapy in controlling massive pulmonary hemorrhage of preterm infants.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
10/28. Focal neurological deficit with sudden onset as the first manifestation of sarcoidosis: a case report with MRI follow-up.stroke as a presenting manifestation of sarcoidosis has rarely been reported. This contrasts with the frequent anatomopathological findings of cerebrovascular involvement in neurosarcoidosis. We present a patient who developed acutely a right brachiofacial weakness and dysarthria. Pulmonary sarcoidosis was found. A brain CT and magnetic resonance imaging (MRI) scan disclosed multiple bilateral ischemic, mainly subcortical lesions. Despite a favorable clinical evolution under adequate corticotherapy, an MRI performed 3 months later showed an increased number of the previously observed lesions. This observation suggests that in some cases the evolution of central nervous system sarcoid lesions occurs independently from corticotherapy, and that MRI, in spite of its known great sensitivity in detecting those lesions, may not play a role in the follow-up of some patients with neurosarcoidosis.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
