RESUMO
We recently identified the efficacy and safety of a botulinum toxin (BTX)-A/B in Raynaud's phenomenon (RP) and digital ulcers (DU) in Japanese patients with systemic sclerosis (SSc). Detailed assessments of peripheral vascular disorder using angiography and dermoscopic images of nail fold capillaries have not been performed previously. This study aimed to evaluate the effect of BTX-B on SSc-associated peripheral vascular disorder. Two SSc patients who suffered with RP and DU were treated with a BTX-B injection, and thereafter the symptoms of RP were improved and DU healed in both patients. Furthermore, angiography showed an increased blood flow to the palm and fingers, and dermoscopic images of nail fold capillary changes showed improvement. These results suggest that a BTX-B injection may increase peripheral blood flow and improve RP and DU in SSc patients.

BACKGROUND: For a safe major hepatectomy, preoperative methods that can reliably estimate postoperative liver function are necessary. The aim of this study was to assess the utility of ICG-R15 measured by pulse dye densitometry to predict residual liver function prior to hepatectomy. PATIENTS AND METHOD: In 29 patients who underwent various types of hepatectomies, indocyanine green (ICG)-R15 was measured by pulse dye densitometry at the time of opening the abdomen (laparotomy phase), clamping the Glisson's pedicles to cutting (clamping phase), and closing abdomen after hepatectomy (resection phase). The relationships among these measurements and postoperative liver function were examined. RESULTS: The mean ICG-R15 was 12.3 +/- 6.0% preoperatively (+/-SD), 9.3 +/- 7.0% at laparotomy, 18.8 +/- 11.6% at clamping, and 20.1 +/- 10.9% at resection. The preoperative and laparotomy and the clamping and resection ICG-R15 values correlated significantly. Eleven (38%) patients developed postoperative hyperbilirubinemia [total bilirubin (T-Bil) >3.0 mg/dl]. The postoperative peak T-Bil correlated significantly with clamping ICG-R15 (r = 0.637, p = 0.0002), but not with preoperative ICG-R15 (r = 0.283, p = 0.137), total clamp time (r = 0.005, p = 0.975), and blood loss (r = 0.097, p = 0.615). Multivariate analysis identified ICG-R15 measured at clamping as the only determinant of postoperative peak T-Bil (r = 0.612). ICG-R15 measured at clamping correlated with the postoperative hospital stay (p = 0.046). CONCLUSIONS: ICG-R15 can be measured in real time during surgery by pulse dye densitometry. ICG-R15 measured by this technique before hepatectomy provides a direct and reliable measure of postoperative residual liver function, thus helping in surgical decision making regarding the extent of hepatectomy.

Three high-concentration vitamin D3 ointments are currently available in Japan for the treatment of psoriasis. The aim of the present study is to investigate the efficacy of high-concentration tacalcitol in patients with psoriasis vulgaris who have already been treated with another high-concentration vitamin D3 ointment, calcipotriol or maxacalcitol. The psoriasis area and severity index score was improved in more than half the patients after changing to the tacalcitol ointment. Many patients treated with maxacalcitol once a day achieved greater clinical improvement by changing to high-concentration tacalcitol. In contrast, some patients who had responded to a high-concentration tacalcitol ointment showed exacerbation after changing to maxacalcitol once a day. Interviews with 50 patients (including the 34 patients enrolled in the present study) indicated that high-concentration tacalcitol ointment was an acceptable therapy in terms of the number of daily applications and drug cost. The results of this clinical study suggest that high-concentration tacalcitol ointment meets the preference of many patients who wish to use an ointment once a day.

The Japanese guidelines for psoriasis therapy with cyclosporin microemulsion preconcentrate (CyA MEPC) has been revised, and the clinical application of CyA MEPC is being expanded to include mild to moderate psoriasis. In this study, we aimed to confirm the clinical efficiency of low-dose cyclosporin therapy in patients with moderate psoriasis vulgaris. After informed consent was obtained, 19 patients with psoriasis vulgaris were enrolled in this study. Each patient basically administrated CyA MEPC, 2.5 mg/kg/day, orally over 12 weeks. When the psoriasis area and severity index (PASI) score showed a 75% reduction from the initial value, the dosage of CyA MEPC was reduced to 1.5 mg/kg/day and added a topical application of active vitamin D3 ointment. We interviewed the patients as to their satisfaction for the usefulness and cost of the treatment. All patients obtained improvement within 12 weeks. In 10 patients whose PASI score reduced over 75%, we could reduce CyA MEPC dosage. No adverse effects were noted in any patients during the treatment. It is of note that the cost for 1.5 mg/kg/day administration of CyA MEPC was accepted by all the patients. In conclusion, this preliminary study suggests that the CyA MEPC is effective, safe and would provide patients with acceptable costs.

We conducted an epidemiological study of systemic sclerosis in Japan using the records of patients who had been registered to receive public financial aid. A total of 10,956 patients were registered as having systemic sclerosis in 1999. We statistically analyzed the data on the patients, including sex, age, major symptoms, and laboratory findings. We also made contingency tables in order to evaluate the correlations of the data. Our study estimated that the male/female ratio was 1:7.3. The mean ages of male and female patients were 58.8 and 58.5 years old, respectively. The major symptoms were as follows: Raynaud's phenomenon 92.4%, skin sclerosis 94.7%, dyspnea 29.9%, and dysphagia 32.2%. With respect to specific antibodies, antinuclear antibody was present in 92.2%, antitopoisomerase I antibody in 27.5%, anticentromere antibody in 37.7%, and antiribonucleoprotein antibody in 19.9%. Making contingency tables, we could elucidate the association of antitopoisomerase I with lung fibrosis.
