Comparison of characteristics of esophageal squamous cell carcinoma associated with head and neck cancer and those with gastric cancer

In ongoing reviews of 339 patients with surgically treated primary squamous cell carcinoma, there were 19 (5.6%) with concurrent gastric cancer and 11 (3.2%) with head and neck cancer. The incidences of intra-esophageal multiple occurrence of esophageal cancer are 27.3% and 26.3% in those with associated head and neck cancer and gastric cancer, respectively, and higher than 7.1% in those without such a concurrent cancer. There was no difference in the clinicopathological characteristics of those with concurrent head and neck and gastric cancers, except for the higher incidence of metachronous occurrence in the former. These findings suggest that, in cases of esophageal cancer associated with concurrent head and neck cancer and gastric cancer, intraesophageal multiplicity of the esophageal carcinoma is frequent and that preoperative serial evaluations is most important to design treatment and estimate the prognosis.     

Positive autoradiographic findings in brains of four MS patients

Autoradiography of brain slices from 4 multiple sclerosis (MS) and 9 control patients was performed. After 6 weeks of exposure the exact picture of the white matter appeared on the X-ray films in all cases with MS, but only in one of the controls. The high level of autoradiographic signal from MS white matter suggests that an abnormal accumulation of radioactive trace elements takes place within the brains of MS victims.     

Immune complexes in CSF and serum in various neurological diseases

A technique whereby immune complexes (ICs) are detected in the CSF and serum from their inhibitory effect on the agglutination of IgG-coated latex particles by rheumatoid factor (RF) has been applied to patients with the following neurological diseases: multiple sclerosis (MS), inflammatory diseases, extradural peripheral neuropathies (EPN), CNS tumors, dementia, and a control group of other neurological diseases (OND). The groups did not differ significantly in respect of IC positivity either in CSF or serum. The MS group was tested for correlations between percentage of IC positives and CSF IgG/Albumin ratio on the one hand and presence of oligoclonal bands on isoelectric focusing on the other. The specificity of ICs to the dysimmune condition is discussed.

Sommario È stata applicata una tecnica di inibizione della reazione di agglutinazione del Fattore Reumatoide (RF) su particelle di latice, ricoperte di immunoglobuline umane, per il dosaggio degli immunocomplessi (ICs) nel liquor e net siero di pazienti affetti da malattie neurologiche. Sono stati considerati 5 gruppi di malattie neurologiche, rappresentate da: sclerosi multipla (MS), malattie infiammatorie, polinevriti, tumori del SNC, demenza ed un gruppo di controllo composto da malattie neurologiche miste (OND).Non sono state riscontrate differenze significative tra le percentuali di positività nei diversi gruppi esaminati, compreso il gruppo di controllo, tanto sul liquor che su siero.Particolare attenzione è stata posta allo studio della MS, ove la percentuale di positività degli ICs è stata raffrontata con il rapporto IgG/Albumina liquorale e con la presenza di bande oligoclonali IgG all'isoelectrofocusing (IEF).La specificità della formazione degli ICs in relazione alla situazione disimmune è stata inoltre discussa.

     

重型颅脑损伤后凝血功能变化的研究

目的研究重型颅脑损伤后凝血功能的变化及临床意义。方法对本院2005年3月至2006年2月收治的26例重型单纯性颅脑损伤患者（GCS≤8分）进行前瞻性研究，监测其入院当时、入院第2天、第3天及第7天的部分凝血活酶时间（APTT），凝血酶原时间（PT），纤维蛋白原（FIB）及凝血时间（TT）的变化。并检测14例单纯头部外伤患者在入院时的APTT、PT、FIB和TT值。结果APTT在入院3天明显升高。1周后仍未达到正常（P〈0．05）；PT在入院当天即升高（P〈0．05），1周左右逐步恢复正常；FIB在入院当天即升高，第3天下降（P〈0．05），1周左右逐步恢复正常。有3例按照DIC诊断标准诊断为DIC，结果在观察期间均死亡。结论重型颅脑损伤后可发生凝血功能异常，且外凝性凝血途径的启动早于内源性凝血途径。伤后早期即可发生高凝状态，至第3天左右向低凝状态转变，1周左右恢复正常。     

全肺放疗治疗双肺多发转移癌24例分析

Predictive value of clinical characteristics for 'benign' multiple sclerosis

We studied a cohort of 496 patients who had multiple sclerosis (MS) for at least 10 years. Ten years after disease onset, 151 had benign MS defined as an Extended Disability Status Scale (EDSS) ≤3. Between benign and non-benign patients we compared gender, age at clinical onset, relapsing–remitting or primary progressive, symptoms at onset, recovery from first relapse, time between first and second relapse, number of relapses in the first 5 years, use of immunomodulatory drugs, and EDSS scores at 2, 5 and 10 years. A multivariate regression analysis showed that a relapsing–remitting course, a low EDSS score at 5 years, and a low number of relapses in the first 5 years were predictive for benign MS at 10 years. Other factors had no additional value. Thirty-five of the 51 patients (69%) with benign MS at 10 years were still benign at 20 years. A low 10-year EDSS score was the only clinical variable associated with a benign course at 20 years. Our results suggest that within the first 5 years from onset it is not possible to predict a benign course. Disease course, EDSS score and relapse rate at 5 years are predictors for benign MS at 10 years.     

Prefrontal cortex dysfunction and depression in atypical parkinsonian syndromes.

Depressive symptoms are common in patients with neurodegenerative disorders. Imaging studies suggest that a disruption of frontal-subcortical pathways may underlie depression associated with basal ganglia disease. This pilot study tested the hypothesis that frontal dysfunction contributes to depression associated with multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). Depressed patients with MSA (n = 11), PSP (n = 9), and age-matched controls (n = 25) underwent measures of cerebral glucose metabolism applying positron emission tomography with (18)F-fluorodeoxyglucose. Regional metabolism in the patient groups was compared to the normal subjects using the voxel-based statistical parametric mapping. Depressive symptom severity (Hamilton Depression Rating) and degree of locomotor disability (Hoehn & Yahr) were assessed in the patient groups. The association between prefrontal metabolism and the occurrence of depressive symptoms and the degree of locomotor disability was investigated. When compared to controls, MSA patients revealed significant metabolic decreases in bilateral frontal, parietal, and cerebellar cortex and in the left putamen. In PSP patients, significant hypometabolism was demonstrated in bilateral frontal cortex, right thalamus, and midbrain. Depression severity but not the patients' functional condition was significantly associated with dorsolateral prefrontal glucose metabolism in both patient groups. The findings of this pilot study support the hypothesis that depressive symptoms in MSA and PSP are associated with prefrontal dysfunction.     

65例多发性硬化患者的临床分析

目的总结多发性硬化(MS)患者的临床特点(精神情感障碍)以及脑脊液、诱发电位、影像学改变进行分析。方法回顾分析65例MS患者的有关临床和实验室资料。结果65例中,男17例,女48例;年龄16~68岁,平均(36.5±14.1)岁,男女比为1∶2.8。MS首发及常见症状为感觉异常、肢体无力、视力减退及括约肌功能障碍,病变部位以脊髓受累最多见,部分患者存在精神情感障碍。结论出现感觉异常有助于MS早期诊断,诱发电位及MRI有助于发现亚临床病变;括约肌功能异常多见,可能与脊髓受累较多有关;MS患者的精神情感应受人们关注。     

58例多原发癌临床分析

Objective to Present 56 cases of multiple primary cancers,to make improvement of diagnosis and treatment.methods A total of 58 patients with multiple primary cancers admitted from 2003 to 2007 were analysed retrospectively in Beijing Tongren Hospital.Results Thirty-five cases were males,with sex ratio of male and female 1.5:1.The median age at the onset of the first disease was 61.5 years (ranged from 27 to 86).The onset age of the two primary cancers was mainly centered around 50～75 years,while half of the second cancers occurred within five years.Conclusion the treatment and prognosis of the two primary cancers are different from that of the recurred and metastatic malignancies and shoule be handled with care.
