SQUAMOUS CELL CARCINOMA IN SOUTHERN AND NORTHERN AUSTRALIA

Squamous cell carcinoma (scc) of the skin was studied in two similar populations, one living in the temperate zone of Australia, the other living in the tropics. In the tropics, the patients were significantly younger, the man to woman ratio approached unity, and women had significantly more sccs on the legs. In the temperate zone, men had significantly more on the head and neck, but women had significantly more on the upper and lower limbs.     

Pemphigus Therapy with Oral Prednisolone Regimens A 5-Year Study

Twenty-two newly diagnosed patients with pemphigus were randomly divided into two groups of 11 each. One group was placed on a high-dose prednisolone (120 mg/day) therapy and the other group on a low-dose (60 mg/day) therapy. The patients were followed for 5 years. Although a rapid initial control of the pemphigus appeared to be achieved with the high-dose regimen, this regimen did not have any long-term benefit over the low-dose regimen with respect to the frequency of relapse or in the incidence of complications.

关于空腹血糖、空腹胰岛素乘积的倒数在流行病学研究中应用的补充说明

高胰岛素正糖钳夹技术可以测定活体的胰岛素敏感性,但它并不适用于大规模流行病学研究。流行病学研究需要简单的胰岛素抵抗测定法。本文补充报告在空腹血糖(FPG)(75～306mg/dl或4.2～17.1mmol/L)及空腹胰岛素(FIns)(9.7～120mU/L)范围很宽的Pima印第安人群中,正糖钳夹技术测定的胰岛素介导的葡萄糖代谢率(M)与涉及FPG、FIns的多种复合的胰岛素敏感指数的相关性:胰岛素作用指数(IAI)=1/(FPG×FIns)在非糖尿病人群及2型糖尿病人群都与M显著正相关(r>0.7,P=0.0001),而且这两者的相关性强于M与其他指数如FIns或FPG/FIns比值的相关性,也不弱于M与糖负荷后3～5个时间点的血糖、胰岛素曲线下面积乘积的相关性。IAI的五分变量分布情况表明有90.4%的IAI落在所预测的M值五分变量区域或与之相邻的一个五分变量区域之内。1/FPG×FIns虽相对简单但确实与机体的胰岛素敏感性密切相关,它可以做为胰岛素敏感指数在流行病学研究中应用。
