Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis is a benign condition of the lymphatic tissue whose cause has not been fully elucidated. Although it has been thought that various viral infections are involved in the onset of the disease, its immunological characteristics expressed by the proliferation of cytotoxic CD8-positive T lymphocytes and histiocytic phagocytosis place it at the border of autoimmunity. Sharing immunological mechanisms, clinical manifestations, and epidemiological data (both are described in young women) with systemic lupus erythematosus (SLE), the association of the two pathologies represents a challenge for both clinicians and pathologists. We present the case of a young woman with SLE with immunological, haematological and articular involvement, who associates a few months after diagnosis the significant swelling of the submandibular glands and latero-cervical lymphadenopathy. Histopathological and immunohistochemical examinations subsequently certify the diagnosis of histiocytic necrotizing lymphadenitis associated with the autoimmune disease.
BACKGROUND. Vestibular disorders are a group of widely spread diseases that have as a common denominator the disturbance of the equilibrium system. The assessment of vestibular disorders consists in a complex examination of the patient including a thorough anamnesis, a rigorous clinical examination and multiple functional explorations. OBJECTIVE. To asses weather there is a correlation between the data obtained in posturography and those obtained in the videonystagmography in patients with peripheral vestibular disorders. MATERIAL AND METHODS. Collecting data from the observation sheets of patients diagnosed with peripheral vestibular syndrome and examined in the Department of Otorhinolaryngology of the “Sfanta Maria” Hospital in Bucharest over a period of 18 months. RESULTS. We analyzed a number of 97 cases of patients diagnosed with peripheral vestibular disorder. A large number of patients (49) had correlated changes in the caloric tests and also in the posturography. A second group of patients (43) had changes in caloric tests but with no changes in posturography. The third group of 5, paradoxically, had a vestibular deficiency in posturography associated with normal caloric reactivity. CONCLUSION. The results obtained with the videonystagmography are correlated with those of the caloric and rotational videonystagmographic tests in the case of acute vestibular diseases. In chronic vestibular diseases, it is possible to find caloric vestibular paresis in the presence of a normal posturography. The “vestibular omission” is a phenomenon in which the patient does not use the vestibular input of a normal labyrinth with caloric and rotary tests within normal limits. As no vestibular examination can be considered as selfstaging diagnosis, we always have to establish the final diagnosis correlating the results of all the tests available.
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.
