青年急性冠脉综合征冠脉造特点及随访

目的:探讨青年急性冠状动脉综合征(ACS)冠状动脉(冠状)造影特点及其与远期心脏事件的关系。方法:比较青年ACS与老年ACS患者冠脉病变程度、范围,并进行心脏事件随访。结果:78例青年ACS患者有冠脉病变74例(94.9％),单支病变46例(58.9％);171例老年ACS患者有冠脉病变166例(97.1％),单支病变41例(23.9％)。平均随访9个月,青年ACS患者发生心脏事件者10例(12.8％),其中心绞痛再入院6例(7.7％);老年ACS患者发生心脏事件者47例(27.5％),其中心绞痛再入院30例(17.5％),两组比较差异有显著性(P<0.05)。结论:ACS患者冠状动脉粥样硬化青年时期之前已经发生,ACS预后与冠脉病变程度和年龄呈正相关。     

TAXUS支架治疗急性冠状动脉综合症的疗效评价

目的评价紫杉醇洗脱冠状动脉支架(TAXUStmBoston公司产品)应用于急性冠状动脉综合症病人的临床疗效及安全性。方法自2003年5月至2004年12月接受TAXUS支架治疗的94例急性冠状动脉综合症患者,观察术后即刻效果、术后6个月心脏性死亡、心肌梗塞、再次血管重建及冠状动脉造影复查情况。病例中包括ST段抬高的急性心肌梗塞27例,非ST段抬高的急性心肌梗死8例,不稳定心绞痛59例。结果支架植入成功率为99%,术中和随访期间无死亡,术后1例出现亚急性血栓,1例晚期血栓致心肌梗塞,另有5例随访中进行了血管重建术,6个月主要心脏不良事件(MACE)发生率7.4%。术后6～7个月23例的冠状动脉造影复查再狭窄率为13.0%(支架内为8.6%),靶病变重建率为2.7%。结论应用TAXUS支架治疗急性冠状动脉综合症是安全和有效的,支架内再狭窄率明显低于普通金属支架。     

重症胆管炎23例临床治疗分析

目的：探讨急性重症胆管炎患者的手术时机和死亡原因。方法：回顾性分析23例急性重症胆管炎患者的治疗及预后情况。结果：死亡2例（手术死亡及传统治疗死亡各1例）。早期大剂量短期应用糖皮质激素患者休克得到纠正率85％，明显高于未用糖皮质激素患者休克纠正率50％。结论：急性重症胆管炎患者应在出现休克和（或）精神症状之前手术，对已出现休克的患者，应先给予充分的保守治疗，待病情稳定后再手术。贻误手术时机，严重合并症如多器官功能衰竭及高龄是死亡的主要原因。     

Glafenine-associated anaphylaxis as a cause of hospital admission in the Netherlands

Summary In 1981 generalized anaphylaxis was registered on 166 occasions in Dutch general and academic hospitals. Clinical details of 120 of those patients revealed that in 107 anaphylaxis was either probable (n=90) or possible (n=17), whereas in 13 cases some other reaction than anaphylaxis had occurred. The series of confirmed cases contained 46 men and 61 women, with mean ages of 47 y and 48 y, respectively.There was a complete recovery in 102 patients and two patients died. Hypotension was present in 79 cases (74%), dyspnoea in 34 cases (32%) and a skin reaction, mainly urticaria, erythema or angioedema, was mentioned in 62 cases (58%). Most cases of anaphylaxis were drug-induced (76%), the main causes being the analgesic glafenine and contrast media. Glafenine was mentioned as the cause in 36% of all admissions for drug-induced anaphylaxis. Only 3.7% of cases had been reported to the voluntary reporting scheme of the Netherlands Centre for Monitoring of Adverse Reactions to Drugs.On the basis of reimbursement data, the risk of developing severe anaphylaxis to glafenine was estimated at 11.7–19.3-fold relative to indomethacin, and 13.4–20.2-fold relative to oral penicillins.     

SARS患者白细胞形态学观察

目的：观察不同病程的严重急性呼吸综合征(SARS)患者白细胞形态的变化。方法：对不同病程SARS患者的血涂片进行形态观察和分析。结果：SARS患者发病期间，其粒细胞比例明显升高，淋巴细胞明显减少，而且出现核仁及多核仁现象，随病程进展，粒细胞、淋巴细胞的比例逐渐恢复至正常范围，有核仁的淋巴细胞也随之减少至消失，均为正常成熟的淋巴细胞。结论：SARS患者发病期间，外周血涂片白细胞分类中，中性粒细胞(分叶核)比例升高，淋巴细胞比例明显减少，随病程进展出现的核仁淋巴细胞减少，血细胞比例、形态恢复正常。

Flavocoxid is as effective as naproxen for managing the signs and symptoms of osteoarthritis of the knee in humans: a short-term randomized,double-blind pilot study

Flavocoxid (Limbrel), a proprietary mixture of flavonoid molecules (baicalin and catechin), was tested against a traditional nonsteroidal anti-inflammatory drug, naproxen, for the management of the signs and symptoms of moderate osteoarthritis (OA) in humans. Discomfort and global disease activity were used as the primary end points, and safety assessments were also taken for both treatments as a secondary endpoint. In this double-blind study, 103 subjects were randomly assigned to receive either flavocoxid [500 mg twice daily (BID)] or naproxen (500 mg BID) in a 1-month onset of action trial. Outcome measures included the short Western Ontario and McMaster University Osteoarthritis Index, subject Visual Analogue Scale for discomfort and global response, and investigator Visual Analogue Scale for global response and fecal occult blood. Both flavocoxid and naproxen showed significant reduction in the signs and symptoms of knee OA (P ≤ .001). There were no statistically detectable differences between the flavocoxid and naproxen groups with respect to any of the outcome variables. Similarly, there were no statistically detectable differences between the groups with respect to any adverse event, although there was a trend toward a higher incidence of edema and nonspecific musculoskeletal discomfort in the naproxen group. In this short-term pilot study, flavocoxid was as effective as naproxen in controlling the signs and symptoms of OA of the knee and would present a safe and effective option for those individuals on traditional nonsteroidal anti-inflammatory drugs or cyclooxygenase-2 inhibitors. A low incidence of adverse events was reported for both groups.     

Zolpidem induced nocturnal sleep‐related eating disorder (NSRED) in a male patient

Nocturnal Sleep‐Related Eating Disorder (NSRED) is a well‐documented sleeping disorder where the person is reported to experience bizarre eating behavior during sleep. Although various causes are implicated in this disorder, role of drugs cannot be ruled out. Here we narrate an interesting rare case report of a drug‐induced new onset NSRED, where a 45‐year‐old man on zolipdem performed an unexpected and bizarre eating behavior during somnambulistic state, type of which has not been reported earlier in the literature. The case falls under even rarer category as such behavior in sleep is reported mainly in woman. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009
