The Neural Correlates of Central Auditory Dysfunction in Chronic Tinnitus: A Multimodal Approach.

Objectives: It was aimed at assessing the connection between tinnitus and central auditory dysfunction using both central auditory tests (CATs) and diffusion tensor imaging (DTI) for brain regions that are crucial for central auditory processing.

Methods: This prospective case-control study included 15 patients with persistent tinnitus and 20 healthy volunteers as controls. They underwent CATs for memory, attention, and DTI.

Circulating CD4+ CD25 high FoxP3+ T cells vary in different clinical forms of leprosy.

Background: CD4(+) CD25(high) FoxP3(+) regulatory T cells (T-regs) were reported to increase in chronic infections. We aimed at studying their frequency in leprosy to investigate their role during Mycobacterium leprae infection.

Methods: Using flow cytometry, the frequency and FoxP3 expression of circulating T-regs was assessed in 38 leprosy patients and 38 healthy controls.

Desmoplastic fibroma--a rare tumour in a rare site.

We report the occurence of a desmoplastic fibroma in the terminal phalanx of the big toe in a 42-year-old male. The tumour is rare, only 66 cases have been reported in the English language journals. The case history together with review of the literature is presented.
