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。     

多发性骨髓瘤合并肾功能不全38例临床和预后分析

目的研究多发性骨髓瘤合并肾功能不全的临床特点及肾功能可逆性的相关因素和生存相关因素。方法回顾性分析1999-01~2003-12北京协和医院收治的91例初治多发性骨髓瘤及其中38例多发性骨髓瘤合并肾功能不全患者的临床资料。结果91例初治多发性骨髓瘤中有38例(41·8%)合并肾功能不全。合并肾功能不全的患者病程进展更快,贫血更严重,血乳酸脱氢酶(LDH)和β2-微球蛋白(β2-MG)质量浓度更高,以及尿蛋白量更多,同时对化疗的反应更差及生存时间更短。其中34·2%的患者肾功能不全是可逆的,血肌酐和LDH是肾功能可逆的独立预测因素。肾功能可逆患者的生存时间与肾功能正常患者的生存时间比较差异无显著性意义。Cox生存多因素分析发现肾功能可逆性(B=1·294,EXP(B)=3·647,P=0·001)是与生存惟一相关的因素。结论肾功能不全是多发性骨髓瘤常见并发症,相当一部分患者的肾功能可以恢复正常,血肌酐水平和LDH水平是肾功能可逆的重要因素,肾功能可逆性是独立的生存预后因素。     

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.     

伴有周围神经病变的多发性硬化

目的分析5例伴周围神经病变的多发性硬化的临床电生理、实验室检查和MRI改变,探讨多发性硬化合并周围神经损害的临床特点和发病机制。方法回顾性总结5例伴发周围神经病损的多发性硬化的脑脊液生化,免疫学检查、寡克隆带,电生理检查,MRI及其它有助于鉴别诊断的检查。结果5例均为伴有周围神经病变的多发性硬化,电生理提示广泛周围神经病损,既有脱髓鞘改变,又有轴突变性。结论由于中枢神经系统与周围神经系统髓鞘存在着共同的抗原性成分,故MS患者的中枢神经系统与周围神经系统可以同时发生脱髓鞘改变。     

多发性骨髓瘤患者止凝血功能的临床研究

目的：观察止凝血功能在多发性骨髓瘤（multiple myeloma,MM)患中的变化。方法：对16例MM患进行全血粘度，血浆粘度，血小板α-颗粒膜蛋白－140（GMP－140，P－选择素），凝血因子Ⅱ、Ⅴ、Ⅶ、Ⅷ、Ⅸ、Ⅹ、Ⅺ活性、抗凝血酶（AT－Ⅲ）活性，纤维蛋白原（Fbg)、纤维蛋白原降解产物D－二聚体（D－D）、纤溶酶原活生（PLG）、组织型纤溶酶原激活性（t-PA)、纤溶酶原激活抑制物（PAI）、α2-抗纤溶酶抑物（α2-PI)及内皮素－1（ET－1），凝血酶调节蛋白（TM）的测定，并交这些指标检测结果与正常对照组进行比较。结果：MM患组全血粘度，血浆粘度，TM比正常对照组明显增高（P＜0．05或P＜0．001），而凝血因子Ⅱ、Ⅷ、Ⅹ活性，Fbg正常对照组明显降低（P＜0．05），其余指标虽有改变，但无统计学意义。结论：MM患存在着血小板功能和凝血功能障碍是临床出血的主要原因，但同时血液粘度增加，血液缓慢不畅，损害毛细血管，也可造成或加重出血。     

The importance of self-examination in the earliest diagnosis of multiple primary cutaneous melanomas: a report of 47 cases

BACKGROUND: Development of more than one primary melanoma in a patient is a relatively uncommon but well-recognized phenomenon. Its frequency has ranged from 1.2% to 8.2% in several series. This subgroup of patients with multiple primary lesions has not been characterized sufficiently. We report the experience of the Melanoma Unit of University Hospital Spedali Civili of Brescia, Italy. METHOD: Study subjects were drawn from 1240 patients with histologically confirmed melanoma, including melanoma in situ. From this group, multiple melanomas developed in 47 patients (3.79%). Every one of our patients has been taught to perform self-examination of the skin to detect suspicious pigmented lesions. RESULTS: Of the 47 patients described in this study, 38 had two primary melanomas, 7 had three melanomas and 2 had 5 and 10 melanomas, respectively. Mean age at first diagnosis was 46.2 years. The majority of subsequent melanomas (74.5%) were removed within 5 years of the initial operation. Synchronous lesions were found in 10 patients. In male patients, the lesion appeared most frequently on the trunk; in female patients, melanoma appeared mostly on the lower extremities. The second primary melanomas developed in the same anatomic region from the first in 53.2% of our patients. The proportion of in situ to invasive melanomas was greater for the second melanomas compared with the first melanomas. Regarding invasive melanomas, the mean thickness of the first melanomas was 1.31 mm compared with 0.66 mm for the second ones. Dividing patients into two groups, of more and less than 50, it is highlighted that in older patients synchronous lesions appear more frequently (36.4% vs. 8.0%); the median time interval between sequential melanomas is longer (84 vs. 63.7 months); and the ratio between the primary and secondary melanoma mean thickness is lower (1.21 : 1.08 vs. 1.43 : 0.63 mm). CONCLUSIONS: The study confirms that second primary melanoma is usually thinner than the first lesion, and it is more common in the same region of the body as the initial melanoma. The highest risk for a second melanoma is during the first 5 years, but a much longer time interval of 28 years is possible. Continued medical follow-up with complete skin examinations seems prudent, but it is very important to promote self-skin evaluation in patients to detect not only metastases but also subsequent primary melanomas in their earliest phases.     

Successful triplet pregnancy in a patient with a unicornuate uterus with a cavitary communicating rudimentary horn

In a patient with primary infertility, ovulation was inducedby monitored stimulation with human menopausal gonadotrophins(HMG) because of polycystic ovarian disease. Infertility work-uphad shown a unicornuate uterus with a cavitary communicatingrudimentary horn. The husband showed a varicocele-related moderateoligoasthenoterato-zoospermia. A triplet pregnancy occurredin a third HMG ovulation induction cycle combined with intra-uterineinsemination of the husband's washed semen. The pregnancy wascarefully monitored, and measures to prevent premature deliverywere taken. Because of the patient's obvious discomfort in thepresence of premature labour, Caesarean section was performedat 33 weeks gestation and three healthy infants were delivered.This is the first report of a successful triplet pregnancy ina women with a unicornuate uterus. The reproductive and obstetricoutcome of this condition in general, and in the case of multiplepregnancy, is discussed.
