ABSTRACT

Cytophagic histiocytic panniculitis (CHP) is a rare panniculitis characterized by systemic features, due to histiocytic infiltration along with haemophagocytosis, which may also appear in bone marrow, spleen, lymph nodes, and liver. Haemophagocytic lymphohistiocytosis (HLH) is a group of autoinflammatory disorders, which include macrophage activation syndrome, sometimes observed in the course of systemic autoimmune diseases, such as juvenile chronic polyarthritis, systemic lupus erythematosus or vasculitis, and infection-associated haemophagocytic syndrome; if not promptly recognised and treated, HLH can be fatal. Visceral leishmaniasis (VL) is a systemic disease caused by different forms of Leishmania spp., an intracellular protozoa. VL is endemic in tropical countries such as in the Middle East and the Mediterranean. The typical clinical and laboratory features are fever, hepato-splenomegaly, hypergammaglobulinaemia and pancytopenia. The features of VL may mimic some haematologic diseases. We report a case of cytophagic histiocytic panniculitis and HLH, triggered by a previous visceral leishmania infection. Cyclosporine was quickly effective in this case, after failure of high-dose glucocorticoids, anakinra and etoposide.

ABSTRACT

Gluconobacter belongs to the acetic acid bacteria (AAB), which are microorganisms commonly found in the environment and used in the food industry. These bacteria have increasingly been reported as organisms that can potentially infect humans. We report a case of Gluconobacter spp. bloodstream infection associated with endocardial lesions in a 25 year-old female intravenous drug abuser. To the best of our knowledge, this is the first case of Gluconobacter spp. endocarditis reported in the literature. For the first time we report that a multiresistant strain belonging to the genus Gluconobacter can cause endocarditis, giving evidence to the fact that this microorganism should be considered a new opportunistic human pathogen.

ABSTRACT

The aim of this study was to establish the presence and the consistency of different cognitive profiles in AD patients taking into consideration the severity of mental impairment. Therefore we stratified 679 neuropsychological observations on 119 probable AD patients followed longitudinally on the basis of overall degree of cognitive impairment. To compare performance on tests with different score ranges we transformed raw test scores into coefficients; to summarize our results in terms of language versus visuo-spatial performance we computed indices of prevalent impairment of performance (IPIP) by subtracting the coefficients for constructional praxis from coefficients for language-related tests. Finally, we converted these indices into z-scores for each level of mental decline to identify patients with generalized, language (L) or visuo-spatial (V) prevalent impairment. The latter, 30% of the sample, can be detected at all stages of dementia. There was a higher percentage of males among language impaired patients (P<0.05). Approximately half of patients with L/V prevalent impairment continued to show such a focality when followed longitudinally. The groups did not differ in the annual rate of cognitive decline.
