Nocardiosis in a kidney-pancreas transplant.

34-year-old man with chronic renal and pancreas failure in complicated diabetic disease received a kidney-pancreas transplantation. On the 32nd postoperative day, an acute kidney rejection occurred and resolved with OKT3 therapy. The patient also presented refractory urinary infection by E. Fecalis and M. Morganii, and a focal bronchopneumonia in the right-basal lobe resolved with elective chemotherapy. During the 50th post-operative day, an intense soft tissue inflammation localized in the first left metatarsal-phalangeal articulation occurred (Figure 1) followed by an abscess with a cutaneous fistula and extension to the almost totality of foot area. The radiological exam revealed a small osteo-lacunar image localized in the proximal phalanx head of the first finger foot. From the cultural examination of the purulent material, N. Asteroides was identified. An amoxicillin-based treatment was started and continued for three months, with the complete resolution of infection This case is reported for its rarity in our casuistry, and for its difficult differential diagnosis with other potentially serious infections.

Bath PUVA and psoriasis: is a milder treatment a worse treatment?

BACKGROUND/AIM: The guidelines of the British Photodermatology Group for topical treatment with psoralen and ultraviolet light (PUVA) recommend starting UVA doses between 0.2 and 0.5 J/cm(2), according to the phototype. Our purpose was to evaluate the therapeutic efficacy and tolerability of bath PUVA, with 8-methoxypsoralen (8-MOP), by using lower UVA doses, regardless of phototype. METHODS: We compared 2 groups of patients (group 1: n = 10, group 2: n = 20) with chronic plaque-type psoriasis. Group 1 was treated with the usual starting dose and dose progression; group 2 was treated by using a lower first dose, a slower dose progression and reaching a lower maximum dose. The Psoriasis Area and Severity Index (PASI) score was assessed at the initial stages, and every month until the end of the treatment. RESULTS: In group 1, the median baseline PASI score decreased from 15.2 to 4.5 (p < 0.005, Student's paired t test), while in group 2, it fell from 13.7 to 4.1 (p < 0.005). No statistical difference between the groups is detectable. Severe phototoxic reactions were observed only in 2 patients of group 1. Side effects were not observed in group 2. CONCLUSIONS: Our data indicate that an aggressive bath PUVA treatment is not substantially more effective in clearing chronic plaque-type psoriasis than a milder therapeutic approach.
