A Rare Case of a Thoracic Spinal Hemangiopericytoma

Open Journal of Modern Neurosurgery 2019年第1期9卷 1-6页

作者： Derou Keableon Louis Irié bi Gohi Serge Tokpa andré Konan Serge Yao Bougaci Nassim Lonjon Michel Neurosurgery Department Bouake Teaching Hospital Bouake Ivory Coast Anesthesia-Intensive Care Unit Bouake Teaching Hospital Bouake Ivory Coast Neurosurgery Department Pasteur Hospital Nice France

Spinal hemangiopericytomas are rare tumors. To date, only 80 cases of spinal hemangiopericytomas have been reported in the literature. The postoperative evolution of this condition in rare cases can be complicated by a symptomatic compressive epidural hematoma that can be the source of serious neurological complications requiring emergency surgery. We report a rare case of intradural and extramedullary spinal hemangiopericytomas with favorable evolution after treatment in an 82 years old woman.

AIM: To elucidate the differences in somatic, psycho-logical and biochemical pattern between the subtypes of irritable bowel syndrome (IBS). METHODS: Eighty IBS patients, 30 diarrhoea pre-dominant (D-IBS), 16 constipation predominant (C-IBS) and 34 alternating IBS (A-IBS) underwent physi-otherapeutic examinations for dysfunctions in body movements and awareness and were compared to an apparently healthy control group (AHC). All groups an-swered questionnaires for gastrointestinal and psycho-logical symptoms. biochemical variables were analysed in blood. RESULTS: The D-IBS group showed less body aware-ness, less psychological symptoms, a more normal sense of coherence and psychosocial rating as well as higher C-peptide values. C-IBS had a higher degree of body dysfunction and psychological symptoms, as well as the lowest sense of coherence compared to controls and D-IBS. They also demonstrated the most elevated prolactin levels. A-IBS had the lowest degree of body disturbance, deteriorated quality of life and affected bi-ochemical pattern. All subtypes had higher pain scores compared to controls. In addition they all had signifi -cantly increased triglycerides and elevated morning cortisol levels, however, without statistical signifi cance compared with the ***: IBS subtypes showed different pro-files in body awareness, somatic and psychological symptoms and in biochemical variables. D-IBS differed compared to the other groups by lowered body aware-ness, less psychological symptoms and a higher sense of coherence and elevated C-peptide values. C-IBS and A-IBS subtypes suffered more from depression and anxiety, associated with a lower quality of life. These differences may be important and will be taken into account in our treatment of these patients.

Cryptosporidium spp. infection is one of the causes of diarrhea in people living with HIV/AIDS. The objective of this study is to compare the sensitivity of microscopy and molecular biology to determine the prevalence of Cryptosporidium spp. in Patients Living With HIV (PLWH). This is a descriptive cross-sectional study conducted in three care centers for people living with HIV/AIDS in Abidjan. It took place from November 2018 to March 2020. Sociodemographic data were obtained via a questionnaire. Stool and blood samples were collected and analyzed for microscopy and Nested PCR detection of Cryptosporidium spp. Blood samples were analyzed for CD4+ count. A total of 363 stool samples were collected from the three sites. Individuals aged 40 - 50 years (36.52%) were most likely to participate in the study. HIV Type 1 accounted for 86.22% of the study population. The samples collected consisted of 47.65% diarrheal stool. Microscopic examination of the stool yielded a prevalence of 3.86% for Cryptosporidium spp. while the prevalence was 3.96% with molecular identification. No statistically significant difference was observed between these two prevalences (χ2 = 0.26;p = 0.609). CD4+ count was the factor associated with Cryptosporidium spp. infection for both microscopy (OR = 0.887, p = 0.001) and PCR (OR = 0.896, p = 0.001). This study demonstrated that Nested PCR improves the detection of Cryptosporidium spp. in patient diagnosis.

采用方差比率法(VR)、χ~2检验、联结系数(AC)、共同出现百分率(PC)、Pearson相关系数、Spearman秩相关系数以及***稳定性测定等数量分析方法,对山西稷山矮牡丹(Paeonia suffruticosa andr. var. spontanea)生存群落中20个优势物种、190个种对间进行种间相关性及群落稳定性分析.结果显示:(1)稷山矮牡丹生存群落20个优势种种群整体表现为不显著负相关性,物种间相对独立,群落稳定性结果(40/60)远离20/80,整体群落不稳定.(2)χ~2检验中不显著关联的对数有168对,占到了88.78%;AC和PC结果都表明20个优势种群落有很大的独立性或随机性,对生境的需求不同,共同出现概率较低;χ~2检验结果、Pearson相关系数半矩阵图、Spearman秩相关系数半矩阵图分别表明检验呈正关联的种对占总对数的38.42%、38.42%、44.74%;检验呈负关联的种对分别占总对数的61.05%、61.05%,54.74%;其中黄刺玫(Rosa xanthina)、连翘(Forsythia suspensa)、辽东栎(Quercus wutaishanica Mayr)与矮牡丹的正相关性相对较显著;黄精(Polygonatum sibiricum)、红柄白鹃梅(Exochorda giraldii)、西北栒子(Cotoneaster zabelii)和黄栌(Cotinus coggygria)与矮牡丹的负相关性相对较显著;(3)根据种群的聚类分析和种间联结测定分析,把矮牡丹生存群落的20个优势种划分为3个生态种组.以上研究表明该群落中种对间的关联性较弱,群落处于不稳定演替阶段,在对矮牡丹保护的同时应加强与其正相关性较强物种在其群落中的保护和建立,促进其群落趋于稳定,以求达到对其实效保护的目的.(图5表6参31)
