中国急性心肌梗塞的疾病经济负担

主要通过对急性心肌梗塞疾病经济负担的研究，总体描述进行二线预防的重要性。资料主要来源于中文文献检索、政府统计报表。主要利用直接医疗费用来计算疾病经济负担，而未考虑直接非医疗费用和间接费用。中日急性心肌梗塞的发病率约为45／10万。55／10万。城市高于农村，男性高于女性。在2000年，急性心肌梗塞的死亡率在城市为32．39／10万，农村为17．99／10万，其死亡率随年龄增长而相应增长。与发病率一样，城市高于农村，男性高于女性。25岁以上人群因急性心肌梗塞而损失的DALY在2000年为3．57DALYs／千人口。怎性心肌梗塞的直接医疗费用在国家卫生部部属医院为28257元／例，省级医院为8663元／例，县级医院为5447无／例。测算2000年急性心肌梗塞的疾病经济负担为13亿元。19亿元。但由于只有10．6％的急性心肌梗塞病人得到临床床治疗，因此，本测算结果可能低估了在中国实际发生的疾病经济负担。     

Epiploic appendagitis and omental infarction: pitfalls and look-alikes

Epiploic appendagitis and omental infarction are benign self-limiting conditions that are more frequent than generally assumed. Both disorders frequently mimic symptoms of an abdominal surgical emergency, often leading to clinical misdiagnosis of appendicitis or diverticulitis. Because a misdiagnosis can result in an unnecessary laparotomy, a correct diagnosis is of great importance. Ultrasound and computed tomography can be used to make a reliable diagnosis. This pictorial essay illustrates the various ultrasonographic and computed tomographic appearances of epiploic appendagitis and omental infarction and focuses on their radiologic differential diagnoses and pitfalls.

马杜霉素渣抗球虫的效果

测定了马杜霉素渣中铅、砷、镉、铬的含量及对小白鼠的毒性和对鸡的抗球虫性能。试验结果：马杜霉素渣中铅含量１．０５ｍｇ／ｋｇ，砷含量小于１．０ｍｇ／ｋｇ，镉含量１．２ｍｇ／ｋｇ，铬含量２６ｍｇ／ｋｇ；马杜霉素渣对小白鼠的ＬＤ５０为３５４．６５ｍｇ／ｋｇ，比马杜霉素毒性大。马杜霉素渣的抗球虫指数为１７３～１７５．１，属中等强度抗球虫药。以上结果表明，马杜霉素渣可以作为抗球虫药应用，但应用时要防止中毒的发生。     

Cholesterol atheromatous embolism: an increasingly recognized cause of acute renal failure

BACKGROUND.: Cholesterol atheromatous embolism is a systemic disease resultingfrom cholesterol crystal embolization to many organs, includingthe kidney. Vascular surgery, vascular radiology investigationsand anticoagulation have been identified as inciting factors. METHODS.: Fifteen patients with extensive atherosclerosis, presentingwith simultaneous occurrence of acute renal failure and peripheralischaemic changes were diagnosed as having acute renal failuredue to cholesterol atheromatous embolism. RESULTS.: The patients, 12 men and three women, had an average age of65 years. In one patient, spontaneous occurrence of the diseasewas observed. An inciting factor was identified in 14 patients:aortography in 10, aortic surgery in two, and thrombolysis intwo. Clinical course of acute renal failure was quite variable.Four patients required dialysis; 11 were conservatively managed.All patients had concomitant skin lesions, including digitalmottling, cyanosis and gangrene of the toes, and livedo reticularisof the lower limb and abdomen. Eosinophilia was the most commonlaboratory abnormality. The diagnosis of cholesterol atheromatousembolism was confirmed by tissue examination in eight; in threeit was based on the finding of retinal cholesterol emboli; infourpatients it was made on clinical grounds. Seven patientsdied within 36 months. Death was most commonly from cardiaccauses. CONCLUSIONS.: Since the population at risk for cholesterol embolism is growingand the disease is iatrogenic in origin, we should expect todetect cholesterol embolism with greater frequency as causeof acute renal failure in the future.     

Referral pattern of patients with oral mucosal lesions in The Netherlands

The referral pattern of 140 Dutch patients with oral mucosal lesions, who had been referred to a Department of Oral & Maxillofacial Surgery and Oral Pathology, shows that patients with oral mucosal lesions consult the dentist as often as the family doctor as the first source of help or information. Furthermore, family doctors were much more used to refer patients with oral mucosal disease to medical specialists rather than to the dentist or the oral and maxillofacial surgeon.     

Outcome of a multicenter treatment program including autologous or allogeneic bone marrow transplantation for de novo acute myeloid leukemia

Abstract: The results of an intensive treatment program for patients 16–60 yr of age with de novo acute myeloid leukemia are presented. The patients were given conventional induction treatment with daunorubicin and cytarabine. Patients not entering complete remission (CR) after 1 course of daunorubicin/cytarabine were given 1 course of amsacrine/etoposide/cytarabine. Those entering complete remission received 3 consolidation courses using mitoxantrone, etoposide, amsacrine and cytarabine. One hundred and eighteen patients were enrolled. Complete remission was attained after 1–2 courses in 90 patients (76%). Another 6 patients reached CR after 3–4 induction courses for a total CR rate of 81%. If feasible, patients were offered either allogeneic or unpurged autologous bone marrow transplantation. Twenty-four patients underwent allogeneic bone marrow transplantation; 15 in first remission, 8 in second remission, 1 in early relapse. Thirty patients below 56 yr of age underwent autologous bone marrow transplantation in first remission. The overall probability of survival at 4 yr was 34%, and for patients below 40 yr of age 50%. Leukemia-free survival was 35% for the whole cohort of patients; 52% for patients below 40 yr of age. Patients undergoing allogeneic or autologous bone marrow transplantation in first remission had an overall survival of 86% and 47%, respectively, while the probability of leukemia-free survival in these groups was 87% vs. 40% at 4 yr. The CR rate and long-term results of this intensive treatment program compare favorably with other recent studies using intensive consolidation with allogeneic or autologous bone marrow transplantation or high dose cytarabine.
