1例安置埋藏式自动复律除颤器病人的随访

埋藏式自动复律除颤器(AICD)能降低恶性快速室性心律失常患者的猝死发生率,已经得到基本肯定,但其猝死率的降低,在相当程度上取决于能否对置入AICD患者进行认真随访,不断完善其治疗。本文报告1例随访16个月经验,并就随访结果,结合文献,略予讨论。     

第Ⅲ段肝管空肠吻合解除肝门部胆管恶性梗阻

肝门部胆管恶性梗阻的治疗仍然十分困难。若不解除胆道梗阻,病人很快因肝细胞功能衰竭而死亡。由于肿瘤在肝门部侵润性生长,直接经肝门的手术往往不可能实现。1980～1993年间,我们采用第Ⅲ段肝管空肠吻合术姑息治疗28例肝门部胆管恶性梗阻的黄疸病人。24例为肝门部胆管癌,2例为胆囊癌,2例为胃癌肝门部淋巴结转移。术后19例病人恢复顺利;5例发生并发症,4例病人手术后死亡。24例存活病人中,19例黄疸完全消退3月以上,手术有效率为79％。4例黄疸再次出现,2例因胆管炎需要入院治疗。作者认为:第Ⅲ段肝管空肠吻合术能有效解除不能切除的肝门部恶性肿瘤病人的胆道梗阻。     

血清LSA测定在恶性肿瘤临床诊断中的初步应用

本文根据Svennerholm和蒋谷人等的方法略加改良,测定了蚌埠地区113例正常人,71例恶性肿瘤患者和82例非肿瘤疾病患者血清脂质结合唾液酸(LSA)的含量。正常值为12.4mg/dl(SD=±3.6mg/dl),71例不同肿瘤患者的平均值为28.2mg/dl(SD=±9.7mg/dl),阳性率为88.7％,82例非肿瘤疾病患者的平均值为16.82mg/dl(SD=±5.4mg/dl),假阳性率为17％。方法的灵敏度,重复性(平均CV=3.6％)和回收率(平均回收率=101.4％)测定结果是满意的。本研究的初步结果表明,血清LSA测定对肺癌、白血病、胃癌和食管癌具有一定的临床诊断价值。     

Desmoplastic malignant melanoma presenting with orbital involvement

Desmoplastic malignant melanoma (DMM) is a rare variant of spindle cell melanoma. We report a case of DMM of the forehead secondarily involving the orbit. The diagnosis was based on light microscopic features, including prominent peripheral cell nest formation and spindle cell fascicles in densely collagenous stroma. Immunohistochemical studies showed strong uniform staining for S100 antigen throughout the tumour. It was negative for HMB 45, smooth muscle actin, desmin, cytokeratins and Type IV collagen. Electron microscopy showed neither melanosomes nor myelin figures. The clinical and histological characteristics of desmoplastic malignant melanoma, and its differential diagnosis of malignant schwannoma, are discussed. DMM has a poor prognosis, since it tends to invade deeply, recur locally and metastasise readily.     

1996-2000年某医院五种恶性肿瘤例均住院费用分析

恶性肿瘤是给群众带来严重健康损害的经济负担的疾病之一,已经列居我国城市 疾病死亡原因的第一位。本研究利用医院为基础的五种恶性肿瘤住院患者的费用数据,分析1996-2000年五种恶性肿瘤患者例均住院费用的变化趋势,比较自费患者和公费患者之间的例均费用差异。根据恶性肿瘤费用水平高、增长幅度快,且公费患者费用明显高于自费患者的情况,提出在医疗保障制度改革的社会环境下,医院必须加强病种费用管理,主动控制医疗费用水平。     

Neuroleptic malignant syndrome in the intensive therapy unit

A case of the neuroleptic malignant syndrome occurred in a 40-year-old male after administration of chlorpromazine while on an Intensive Therapy Unit. Treatment with dantrolene sodium was successful, and a muscle biopsy was examined in the recovery phase of the illness. The importance of this condition and the difficulties in establishing a diagnosis at an early stage in patients on an Intensive Therapy Unit are discussed, along with implications for treatment.     

Cardiac arrest after isoflurane anaesthesia in a patient with Duchenne''s muscular dystrophy

An 8-year-old boy known to have Duchenne's muscular dystrophy suffered a cardiac arrest 10 minutes after he regained consciousness after isoflurane anaesthesia for an orchidopexy procedure. Resuscitation was successful 2 hours after the start of external cardiac compression and after correction of hyperkalaemia and the administration of dantrolene. He later developed myoglobinuria elevated creatine kinase and a metabolic and respiratory acidosis. He demonstrated a delayed increase in rectal temperature.     

Endoscopic fistulotomy and biliary drainage as the ultimate palliative treatment for obstruction due to malignant tumors of the papilla of Vater

Summary This report describes the technique and results of endoscopic fistulotomy as a drainage procedure in cases of malignant obstruction of the biliary system from bulky and friable growths in the papilla of Vater. Fistulotomy, coupled with insertion of stents, was successful in seven of eight patients and was associated with relief of jaundice. It is suggested that the method be applied when conventional transpapillary insertion of stents is impossible either due to distortion of the papilla or bleeding of the growth on touch.     

Development of an animal model for neuroleptic malignant syndrome: heat-exposed rabbits with haloperidol and atropine administration exhibit increased muscle activity, hyperthermia, and high serum creatine phosphokinase level

The neuroleptic malignant syndrome (NMS) is a life-threatening complication of neuroleptic treatment. To elucidate the pathogenesis of NMS, an animal model has been developed. Experimental rabbits treated with haloperidol (1 mg/kg) by intramuscular injection, were studied for the diagnostic symptoms of increased muscle rigidity, elevated body temperature, and high serum creatine phosphokinase (CPK) level. Administration of haloperidol (1 mg/kg) and atropine (0.4 mg/kg), and exposure to high ambient temperature (35°C) induced a significant increase in electromyographic activity with muscle rigidity similar to that observed in patients with NMS. Such rabbits also showed elevated body temperature and serum CPK value. In addition to the similarity of the signs and symptoms, all parameters measured (muscle rigidity, body temperature, and serum CPK level) were normalized by dantrolene treatment. The effectiveness of dantrolene in the experimental animal partially confirms the validity of this animal model for NMS. This experimental animal model for NMS may be useful to elucidate the pathogenesis of NMS.     

Surgical management of insulinoma: Diagnosis of tumor location and high incidence of malignancy

The findings in twenty-two patients with insulinoma were reviewed, as continuous efforts should be made to establish preoperative localization of the tumor. Superselective arteriography and percutaneous, transhepatic portal vein and pancreatic venous catheterization are highly recommended approaches. At the time of surgical intervention, a cautious exploration of the pancreas after thorough mobilization is most important. Recent use of intraoperative ultrasonography increases the likelihood of finding these occult tumors which locate deeply in the head of the pancreas. Apart from the diagnostic problems, we wish to emphasize the high incidence of malignancy (7/22, 31.8 per cent) in our series. Althout patients with malignant isulinoma had a much better prognosis compared to those with a pancreatic ductal malignancy, pancreatic resection with regional lymphnode dissection seems to be a rational procedure. Enucleation can be done when intraoperative findings of the tumor and regional lymphonode indicate no malignant features and no multiple lesions. However, at the first operation, enucleation is still a procedure of choice, even for the malignant insulinoma in the head with a well-defined capsule and no metastatic lesions, the objective being to avoid a duodenopancreatectomy or total pancreatectomy. These data were reported at the 30th Congress of Société Internationale de Chirurgie, Hamburg, Germany, 1983
