Acute pulmonary thromboembolism is a critical and sometimes fatal event that is difficult for clinicians to diagnose because of its various initial manifestations. Here, we report a previously healthy 50-year-old man without any history of seizures who presented to the emergency ward with the new-onset seizure. Neurology consult was performed, but found no focal neurological deficits. The diagnosis of massive pulmonary embolism was confirmed by echocardiography and pulmonary CT angiography. Alteplase and heparin with therapeutic dosage were started for the patient. After initiating treatment, patient’s dyspnea, arterial O2 saturation, and general condition were significantly improved. Echocardiography was repeated and showed a smaller right ventricle size and lower pulmonary artery pressure than the first echocardiography.
Background Brucellosis is a bacterial disease caused by Brucella species. The purpose of this study was to evaluate brucellosis in all types of transplant patients. Methods All the cases of brucellosis in transplant patients with no time and language limitations were searched and retrieved on May 20, 2020, using the following search keywords: (Brucella OR Brucellosis) AND (Transplant OR Transplantation) through the following medical databases: Web of Sciences, Google Scholar, Scopus, PubMed, and regional databases, for example, SID. All clinical features, including the time of transmission (before, during, and after transplantation), treatment protocols and medications, and patients’ outcomes were investigated. Results A total of 14 cases reported in 14 studies (out of 777 studies) were retrieved. Kidney (50%), liver (28.5%), and hematopoietic stem cell transplantation (14.2%) were the most reported types of transplantation. The presentation of brucellosis in 42.8% of the patients occurred in the early post‐transplantation period, whereas 57.1% of the cases presented with late onset disease. Conclusion Brucellosis in transplant recipients seems to be uncommon even in the endemic regions. However, rare cases could be transmitted through bone marrow transplantation and transfusion. Precise screening and meticulous supervision during and after transplantation might lead to a reduction in the frequency of brucellosis.
Canavan disease is a rare fetal inherited leukodystrophy, caused by accumulation of N-acetyl-aspartate in the brain. Here, we report a child presented with frequent intractable seizures and visual impairment. A 14-month-old female infant with a complaint of the absence of neck holding and generalized tonic-clonic seizures was referred to our hospital. Macrocephaly, setting sun eyes, tremor, and hypotonia were observed. Funduscopy showed optic atrophy. Our patient’s flash visual evoked potential showed blindness. Her brain magnetic resonance imaging showed diffuse white matter in subcortical, basal ganglia, and dorsal pons. Electroencephalography showed diffuse slow and sharp waves. The genetic study detected a hemizygous mutation in the aspartoacylase gene. Our patient was diagnosed with Canavan disease and began anticonvulsant treatment. However, seizures were not under control. Then, her medications were discontinued, and clobazam and primidone were administered. In conclusion, starting clobazam and primidone may help prevent frequently intractable seizures in Canavan disease patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
