High tension electrical burns

Summary In this study, 85 patients with high-tension electrical burns who were seen in an 11 year period were reviewed. Only victims with documented passage of high-tension electrical current (more than 1000 volts) through the body were included. A total of 210 operations were performed for exploration, debridement and closures of the injuries; 44 cases underwent a total of 65 amputations. Acute renal failure developed in two cases (2.3%) and both died. No cases of clostridial infection occurred. Four patients (4.7%) died in this series. We came to the conclusion that the primary treatment of these burns must include aggressive fluid resuscitation and early aggressive debridement.Presented at the IV European Burns Congress in Barcelona, Spain, September 23–26, 1991     

PTSD among vietnam veterans: An early look at treatment outcome using direct therapeutic exposure

Vietnam combat veteran inpatients were evaluated after being treated in a PTSD special treatment unit. Selected pretreatment measures that included mental and physical problems, combat variables, PTSD symptoms, and the standard MMPI scales found no clinically meaningful differences between a group that was found to be successes and another group found to be failures, based on predetermined cutoff scores on the VETS scale, a reliable outcome measure for veteran patients. At 3 months post-therapy, a significantly greater number of subjects treated with Direct Therapeutic Exposure (DTE) (flooding therapy) as compared to another group treated with a more conventional individual therapy, were identified as successes as opposed to failures, based on the VETs scale. Also, the number of failures was greater for those treated with the more conventional therapy and the number of successess was greater for those treated with DTE, when compared to all other subjects in the sample. These preliminary results were interpreted as indicating that DTE, when offered as part of an inpatient milieu, shows promise as an effective treatment for chronic/severe combat veteran PTSD sufferers.     

Efficacy and safety of carvedilol in comparison with atenolol in hypertensive patients pretreated with hydrochlorothiazide

Carvedilol [25 mg once daily] (o. d.) was compared to atenolol (50 mg o. d.) as an adjunct to pre-existing hydrochlorothiazide (HCTZ) monotherapy in patients with mild to moderate hypertension [diastolic blood pressure (DBP),100–115 mm Hg]. After a placebo run-in phase of 2 weeks, 131 patients received 25 mg HCTZ o. d. for 4 weeks. In all, 122 patients were transferred to the double-blind phase, in which 25 mg carvedilol or 50 mg atenolol was randomly added to HCTZ. After an additional 6 weeks of treatment, 112 patients were evaluable for efficacy (C/HCTZ group,n = 54; A/HCTZ group,n = 58). Blood pressure was measured and the heart rate was counted before medication, at 2-week intervals throughout the trial, and 2 h after medication on the 1st and the last day of the combination treatment period. Serum lipids were measured in addition to routine laboratory variables.

Cyclical use of tamoxifen and high-dose medroxyprogesterone acetate in advanced estrogen receptor positive breast cancer

Summary One-hundred and seventy patients with estrogen receptor positive (10 pmol/g protein) advanced breast cancer have been treated in a prospective randomized study either with continuous tamoxifen 30 mg × 1 daily (TAM), or with TAM 30 mg × 1 daily for 8 weeks alternating with medroxyprogesterone acetate 500 mg × 2 daily for 8 weeks (TAM/HD-MPA). The response rate was 62% in the group treated with cyclic TAM/HD-MPA versus 41% in the TAM alone group (p = 0.02). There was no significant difference in duration of remissions or survival.     

经皮射频毁损治疗原发性肝癌

目的 评价射频毁损（RFA）治疗原发性肝癌（HCC）的近期疗效、安全性及并发症。方法 采用RF－2000型射频治疗仪,在B超引导下经皮治疗78例HCC患者。结果 78例患者（肝功能Child分级：A级58例,B级14例,C级6例）的110个肿块（平均直经6.1cm,1.9-13.7cm）共进行了105次治疗,平均治疗1．3次和6．3个点,平均随访9．2个月（1－16个月）。患者术后肝功能轻度损害,2周左右恢复正常。最常见的不良反应为低热。6例（7．7％）出现并发症,未发生与RFA治疗直接相关的死亡。43例（55．1％）复发,平均发生在治疗后6．1个月。多因素相关分析显示,原位复发与肿块直径呈显著正相关（P＝0．0001）。无原位复发者其治疗点数与肿块直径存在线性关系（r=0.77216,P=0.0001),回归方程式为y=-1.794 1.733x。结论 RFA是一种治疗HCC安全有效的非手术方法。

四氧嘧啶致大鼠高血糖模型的实验研究

目的：探讨四氧嘧啶至Wistar大鼠高血糖模型的最佳实验条件。方法：根据不同条件对实验动物进行分组,使用四氧嘧啶腹腔注射导致动物产生高血糖,计算成模率和死亡率。结果：采用两次给药法,在给药剂量分别为120mg/kg(第1天）和100mg/kg（第2天）的条件下,随着体重的增高其成模率呈下降趋势。两次给药法的两组剂量（120mg/kg第1天,100mg/kg第2天;120mg/kg第1天,80mg/kg第2天）对成模率没有影响,剂量降低可减少死亡率。日照时间短,强度低,成模率明显降低,而且死亡率明显增高。结论：用四氧嘧啶制备糖尿病模型是一种经济可靠的实验方法。但实验条件要求较为苛刻。实验选取雄性Wistar大鼠,体重190-240g,在日照时间10h以上且阳光充足的条件下饲养。给药方式采取两步给药法,剂量为120mg/kg第1天,100mg/kg第2天,其成模率最高。

结直肠癌并肝转移的手术治疗

目的：探讨结直肠癌肝转移的手术切除效果。方法：回顾分析结直肠癌并肝转移32例的临床资料,着重手术切除效果的分析。结果：32例结直肠癌肝转移患者中肝脏有1-3个转移灶者24例,在20例为同时性肝转移癌中,转移性与原发灶行一期切除者15例,分期（2-4周后）切除者5例。5例为结肠肝曲癌局部浸润转移。与原发灶整块切除,其它手术方式有不规则肝部分切除,肝左外叶切除,肝右后叶切除,肝右叶切除及肝右3叶切除等。全部病例均病理检查证实,无手术死亡,3年、5年生存率分别为37.5%和25.0%。结论：肝转移灶数目是影响疗效的主要因素。对肝转移灶手术切除是最有效的方法。但应合理选择具体手术方式。
