ABSTRACT
Pigs of Belgian Landrace (B), Duroc (D), Hampshire (H), and Pietrain (P) breeds were slaughtered at 90, 110 and 130 kg body weight (BW) and the carcass chemical composition and fatty acid profiles of intramuscular fat of loin and backfat were determined. The carcass of Pietrain pigs had a higher concentration of protein and less fat than of B, D and H breeds. In tissues, the PUFA:SFA ratio was lower in the heavier (130 kg BW) than in lighter pigs (90 and 110 kg BW). This feature was higher in P pigs compared with the other breeds. The backfat had a higher concentration of PUFA:SFA ratio than intramuscular fat. The PUFA n- 6:n- 3 ratio was not affected by the breed and weight of pigs, but it was lower in backfat than in longissimus muscle fat. The protein concentration in the carcass was positively related to PUFA and negatively to SFA concentration in tissues.

BACKGROUND: The literature data on the recurrence of autoimmune hepatitis (AIH) after orthotopic liver transplantation (OLTX) is scanty. METHODS: We analyzed the frequency of recurrent AIH in 47 patients who had been transplanted for AIH and survived at least 1 year after surgery. The following criteria were applied to diagnose recurrence: (1) positive autoantibodies in the titer> or =1:40; (2) hypertransaminasemia; (3) histological features of chronic hepatitis; (4) need of reintroduction or significant increase of steroids; and (5) lack of serum markers of viral hepatitis. RESULTS: A total of 13 patients (1 male/12 females) developed recurrent AIH after an interval of 6-63 months after OLTX (mean 29 months). Mean AST level at recurrence was 542+/-129 U/L. Three patients from this group needed regrafting. Mismatch of DR3+ recipient and DR3- donor was not more common in the recurrent disease group (37%) compared to the nonrecurrence group (31%) (P=NS). CONCLUSIONS: Recurrence of AIH after OLTX was diagnosed in a high proportion of patients and some of them required regrafting. DR3+ patients are not particularly prone to develop recurrence.

Acquired perforating dermatosis (APD) is a very rare disorder which has been described in association with systemic diseases such as diabetes mellitus, HIV infection or lymphoma. In this report we describe a patient with APD associated with sclerosing cholangitis and diabetes mellitus who was successfully treated with rifampicin. A 33-year-old Indian woman with a history of extensive pancreatic surgery, sclerosing cholangitis and insulin dependent diabetes mellitus was referred to our unit with intractable pruritus. She was treated with cholestyramine, ursodeoxycholic acid, several analgesics, UVB therapy, topical steroids, sedative antihistamines and plasmapheresis without significant improvement. Increasingly severe itching was associated with papular skin changes limited initially to the lower limbs but which later involved her entire body. Biopsy of a representative lesion showed the changes of APD. She was subsequently treated with rifampicin which produced a dramatic resolution of pruritus within 3 weeks and the skin changes progressively resolved over subsequent months. In this newly described association of APD with sclerosing cholangitis, rifampicin treatment appeared to be efficient in ameliorating pruritus and the papular skin changes typical of APD.
