Prednisone or prednisolone are the mainstay drug treatments for autoimmune hepatitis in children. However, long-term use of corticosteroid is associated with the risk of steroid-induced toxicities, and this situation requires newer immuno-suppressive agents for the treatment of autoimmune hepatitis, especially in growing children. An 11-yr-old Korean girl with type-1 autoimmune hepatitis discontinued prednisolone due to toxicities, i.e., hirsutism, buffalo hump, and skin striae, and remained clinical and biochemical remission under replacement of deflazacort and ursodeoxycholic acid combination therapy. A follow-up liver biopsy after 19 months of deflazacort and ursodeoxycholic acid treatment showed histologic remission.

Idiopathic retroperitoneal fibrosis (IRPF) is a rare disease characterized by a retroperitoneal inflammatory proliferative fibrosing process. Hashimoto's thyroiditis is the most common inflammatory condition of the thyroid gland; and is a frequently-occurring autoimmune disorder manifesting predominantly in middle-aged women. We report a rare association of IRPF with Hashimoto's thyroiditis in a 67-year-old man demonstrating good response to steroid therapy.

Synchronization of estrus and ovulation are of paramount importance in modern livestock improvement programs. These methods are critical for assisted reproduction technologies, including artificial insemination and embryo transfer, that can increase productivity. In the current study, subcutaneous implants containing norgestomet were placed for long (14 days), medium (9 days), and short (5 days) periods of time in 70 crossbred ewes undergoing fixed-time artificial insemination. The resulting effects on estrus synchronization and conception rates were subsequently evaluated. Among the synchronized ewes, 85.7% (60/70) underwent estrus over a period of 72 h after progestagen treatment ceased. The shortest mean interval between withdrawal of the device and onset of estrus (34.2 +/- 8.9 h) was observed in the G14 days of P4 group (p < 0.05). The conception rate of the G14 days of P4 group was statistically higher than that of the other groups (83.3% vs. 60.9% vs. 47.8%; p < 0.05). In conclusion, 14 days of norgestomet treatment produced higher conception rates and a greater number of pregnancies at the beginning of the breeding season.

OBJECTIVE: To determine the feasibility of using T2 mapping as a quantitative method to longitudinally follow the disease activity in children with Duchenne muscular dystrophy (DMD) who are treated with steroids. MATERIALS AND METHODS: Eleven boys with DMD (age range: 5-14 years) underwent evaluation with the clinical functional score (CFS), and conventional pelvic MRI and T2 mapping before and during steroid therapy. The gluteus muscle inflammation and fatty infiltration were evaluated on conventional MRI. The histograms and mean T2 relaxation times were obtained from the T2 maps. The CFS, the conventional MRI findings and the T2 values were compared before and during steroid therapy. RESULTS: None of the patients showed interval change of their CFSs. On conventional MRI, none of the images showed muscle inflammation. During steroid treatment, two boys showed increased fatty infiltration on conventional MRI, and both had an increase of the mean T2 relaxation time (p < 0.05). The remaining nine boys had no increase in fatty infiltration. Of these, three showed an increased mean T2 relaxation time (p < 0.05), two showed no change and four showed a decreased mean T2 relaxation time (p < 0.05). CONCLUSION: T2 mapping is a feasible technique to evaluate the longitudinal muscle changes in those children who receive steroid therapy for DMD. The differences of the mean T2 relaxation time may reflect alterations in disease activity, and even when the conventional MRI and CFS remain stable.
