Ecology and distribution of hypogeous fungi from Sicily (southern Italy)

The distribution and ecology of 39 hypogeous and semi-hypogeous fungi is reported. Ten taxa, including the rare Fischerula macrospora, are new records for Sicily, while the presence of some species, previously reported by Oreste Mattirolo, is confirmed

Diffuse granulomatous necrotizing scleritis.

CASE REPORT: A 34-year-old man presented with anterior scleral thinning in the right eye (RE) and a painful nodular scleritis in the left eye (LE). Fundus examination showed a healed vasculitis and an inferior epiretinal neovascular membrane in the LE. Topical and systemic oral steroids and antiviral medication were prescribed. One year later, optic disc hyperaemia and swelling and macular oedema became apparent in the LE. Pulsed intravenous steroids were administered for 1 year, when a nasal septum perforation and vitreous haemorrhage in the LE were diagnosed. The eye was enucleated 3.5 years after the initial complaint. Necrotizing granulomatous tissue replacing the sclera and subconjunctival granulomatous tissue were observed. Six months later, oedema and neovascularization of the right optic disc were observed and cyclophosphamide was started, with regression of the clinical signs. No systemic abnormalities have so far become apparent. Discussion: Posterior scleritis is most often observed in patients with no signs of associated systemic autoimmune disease. The diagnosis in this case is most probably one of Wegener's granulomatosis (WG). In WG, the diagnosis is based on necrotizing granulomas of the respiratory tract, generalized focal necrotizing vasculitis and focal necrotizing glomerulonephritis. Eye involvement with WG has been reported in up to 58% of cases. Evaluation of the scleritis patient should include a detailed medical history, chest X-rays, blood tests, autoantibody serology and analysis of urinary sediment. Cyclophosphamide is the treatment of choice for patients with ocular manifestations of WG, polyarteritis nodosa or rheumatoid arthritis, either alone or in combination with systemic steroids. Visual loss is expected in 85% of individuals with severe necrotizing posterior scleritis
