Psoriasis is an inflammatory skin disease characterized by hyperproliferation and incomplete differentiation of keratinocytes. Mounting scientific evidence suggests that this epidermal alteration occurs as a response to an immunologic injury, giving rise to the concept that psoriasis is a skin-specific autoimmune disease. Indeed, many effective therapeutic agents for psoriasis are immunosuppressive in nature, lending further support to this view. The well known ability of calcipotriene and 1,25(OH)2D3 to inhibit keratinocyte proliferation and to induce its differentiation is certainly compatible with their antipsoriatic actions. In addition, topical calcipotriene has been shown to correct, at least in part, the local cytokine imbalance observed in psoriatic lesions. Interleukin (IL)-8 is a proinflammatory cytokine that is chemotactic for polymorphonuclear cells and T lymphocytes. It also promotes proliferation of keratinocytes and endothelial cells. In lesional psoriatic skin, IL-8 and its receptor levels are markedly elevated. IL-10 is an immunosuppressive cytokine, which as a type2 (T2) cytokine antagonizes cell-mediated immunity. Indeed, IL-10 administration has been shown to improve psoriasis. Topical calcipotriene markedly reduces elevated levels of IL-8 while simultaneously increasing IL-10 levels in lesional skin of psoriasis. These changes occur very early, within the first three days of therapy, prior to significant clinical improvement of psoriasis, indicating that the cytokine alterations are not simply secondary to resolution of psoriatic plaques. Therefore, elaboration of the immunosuppressive cytokine IL-10 and a concomitant reduction in the proinflammatory cytokine IL-8 may mediate the immunopharmacological improvementin psoriasis by calcipotriene.

4. Prostate-specific antigen density predicts favorable pathology and biochemical recurrence in patients with intermediate-risk prostate cancer
Asian Journal of Andrology 2016;18(3):480-484
This study was designed to identify clinical predictors of favorable pathology and biochemical recurrence (BCR) in patients with intermediate-risk prostate cancer (IRPCa). Between 2006 and 2012, clinicopathological and oncological data from 203 consecutive men undergoing robot-assisted radical prostatectomy (RARP) for IRPCa were reviewed in a single-institutional retrospective study. Favorable pathology was defined as Gleason score ≤6 and organ-confined cancer as detected by surgical pathology. Logistic regression analysis was used to determine predictive variables of favorable pathology, and the Kaplan-Meier and multivariate Cox regression model were used to estimate BCR-free survival after RARP. Overall, 38 patients (18.7%) had favorable pathology after RARP. Lower quartile prostate-specific antigen density (PSAD) was associated with favorable pathology compared to the highest quartile PSAD after adjusting for preoperative PSA, clinical stage and biopsy Gleason score (odds ratio, 5.42; 95% confidence interval, 1.01-28.97; P = 0.048). During a median 37.8 (interquartile range, 24.6-60.2) months of follow-up, 66 patients experienced BCR. There were significant differences with regard to BCR free survival by PSAD quartiles (log rank, P = 0.003). Using a multivariable Cox proportion hazard model, PSAD was found to be an independent predictor of BCR in patients with IRPCa after RARP (hazard ratio, 4.641; 95% confidence interval, 1.109-19.417; P = 0.036). The incorporation of the PSAD into risk assessments might provide additional prognostic information and identify some patients in whom active surveillance would be appropriate in patients with IRPCa.

Osteonecrosis of the femoral head seems to be due to circulatory disturbance of the femoral head, usually idiopathic in origin, but also associated with chronic alcoholism, gout, prolonged treatment with corticosteroids, sickle cell disease, Caisson's disease and surface and degenerative changes in the hip joint. Aims of this procedure are to decompress the femoral head hence allowing better circulation, to revitalize the dead head by insertion of vascularized pedicle bone and to give a mechanical support preventing further collapse of the femoral head. Authors reviewed 19 cases of the vessel pedicled iliac bone graft performed for the idiopathic osteonecrosis of femoral head from January, 1984 to April, 1988 with follow-up periods from 23 months to 66 months, average 37.5 months. The purpose of this follow-up note is to report the long term follow-up result and to show the critical points of this technique.

There are many controversies concerning therapeutic guidelines for the treatment of Kienbock's disease. We experienced 17 cases of stage II or III Kienbock's disease(Lichtman's classification), which were treated with triscaphe fusion from March 1983 to March 1992. The mean Follow-up peri- od was 25 months. The purpose of this study is to evaluate the clinical and radiological result of triscaphe fusion of 17 cases of Kienbock's disease. 1. The pain was relieved in all cases, but range of motion was not improved after operation. 2. The postoperative results of triscaphe fusion were evaluated by Licthman's method. 9 cases (53%) were rated as satisfactory and 8 cases as unsatisfactory. 75%(3 cases of 4) were rated sat isfactory in IIIA a group and 22%(2 casaes of 9) were rated satisfactory in IIIB group. 3. The psudoarthrosis was noted in 2 cases of 17.

Characterizations of the VP4 (P type) and VP7 (G type) genes of Korean isolates of bovine rotavirus were performed using RT-PCR/RFLP and nucleotide sequencing analysis. After RT-PCR amplification of partial length (1094bp) of the VP4 and full length (1062bp) of the VP7 genes, amplified PCR products were digested with restriction endonucleases and digestion patterns were compared with those of reference rotaviruses. With the VP4 genes, four RFLP (AD) profiles were observed; three (A, B and C) were the same as those of bovine rotavirus NCDV (P[1]), IND (P[5]) and B223 (P[11]), respectively, Profile D was the same as that of porcine rotavirus OSU (p[7]). With the VP7 genes, five RFLP profiles (I-V) were observed; three of them (1, II and III) were the same as those of bovine rotavirus NCDV (G6), Cody I-801 (G8), and B223 (G10), respectively, Profile IV and V were atypical to those of reference bovine rotaviruses used in this study. These two profiles were identified as G6 and G5, respectively, after analyzing and comparing the nucleotide sequences. The G typing analysis revealed that 61.9% (26/42) were G6, which included G6 subtype; 28.6% (12/42) were G5; 7.1% (3/42) were G10; 2.4% (1/42) were G8. The P typing analysis revealed that 54.8% (23/42) were P(5); 28.6% (12/42) were P(7); 11.8% (5/42) were P(11); 4.8% (2/42) were P(1). Our results showed that G6/P(5) were the most prevalent rotaviruses in diarrheic calves in Korea. Also, this is the first report that G5P(7) rotaviruses were identified from cattle with diarrhea.
