Introduction: Calcified forms with pseudo-tumor symptomatology of chronic subdural hematomas are rare. They are the result of slow bleeding over several years. The main etiology is related to the complications of the ventriculo-peritoneal shunt (VP). The purpose of this study was to recall the peculiarities and physiopathology of its pseudotumoral hematomas through 2 observations. Observation: Case 1: 8-year-old patient with a history of ventriculoperitoneal shunt at 3 months of age for congenital hydrocephalus, was admitted for functional impotence of the left-side of the body of insidious onset spreading over 9 months in a chronic headache, blurred vision and generalized seizure. CT scan showed a heterogeneous subdural hematoma of the right frontoparietal with calcifications. The patient underwent an excision by morcellation of a yellowish, friable partly calcific mass. The postoperative history was marked by a total recovery of the neurological deficit. There was no recurrence at 6 months postoperatively. Case 2: 11-year-old adolescent, treated with VP shunt at 6 months of age for post-meningitic hydrocephalus, was admitted for helmet headache, dizziness, lightheadedness and apathy progressing for 3 years. CT scan showed hypodensity of right peri-hemisphere with calcified linings, exerting a mass effect on the medial structures. The patient was given a block excision of a calcific mass with blood content. The evolution was marked by the complete resolution of seizures and hemiparesis. There was no recurrence at 6 months postoperatively. Conclusion: Calcified subdural hematomas are rare and consecutive to the complications of VPS. The clinical signs are those of a benign brain tumor. Treatment is dominated by the difficulties of cerebral reexpression.

Chronic Subdural Hematoma Associated with an Arachnoid Cyst in Elderly, an Intraoperative Finding after Re-Bleeding: Case Report

引用

Open Journal of Modern Neurosurgery 2024年第1期14卷 57-63页

作者： Komi Egu Agbéko komlan doléagbénou Messan Hobli Ahanogbé Abdel Kader Moumouni Essossinam Kpélao Katanga Anthony Békéti Department of Neurosurgery Sylvanus Olympio Teaching Hospital Lomé Togo Department of Neurosurgery Kara Teaching Hospital Kara Togo

Intracranial arachnoid cysts (AC) are believed to be congenital and chronic subdural hematomas tend to occur in elderly patients with a history of mild head injury. The association between these two entities sporadically occur in relatively young patients but rare in elderly patients. We report a 65-year-old man who presented with headache and dizziness of 2 months’ duration with a history of head injury. Brain computed tomography (CT) a CSDH in right side and a hygroma in left side. After first operation with burr holes in both sides, the patient underwent an early recurrence of acute subdural hematoma in the right side. The evacuation of this hematoma by a craniotomy allowed seeing an AC that we resected partially with complete recovery of the patient. The association CSDH/AC is rare and possible in elderly patients and there is no consensus on treatment.

Satellite monitoring of land-use and land-cover changes in northern Togo protected areas

Remote-sensing data for protected areas in northern Togo, obtained in three different years （2007, 2000, and 1987）, were used to assess and map changes in land cover and land use for this drought prone zone. The normalized difference vegetation index （NDVI） was applied to the images to map changes in vegetation. An unsupervised classification, followed by classes recoding, filtering, identifications, area computing and post-classification process were applied to the composite of the three years of NDVI images. Maximum likelihood classification was applied to the 2007 image （ETM＋2007） using a supervised classification process. Seven vegetation classes were defined from training data sets. The seven classes included the following biomes： riparian forest, dry forest, flooded vegetation, wooded savanna, fallows, parkland, and water. For these classes, the overall accuracy and the overall kappa statistic for the classi- fied map were 72.5% and 0.67, respectively. Data analyses indicated a great change in land resources; especially between 1987 and 2000 proba- bly due to the impact of democratization process social, economic, and political disorder from 1990. Wide-scale loss of vegetation occurred during this period. However, areas of vegetation clearing and regrowth were more visible between 2000 and 2007. The main source of confusion in the contingency matrix was due to heterogeneity within certain classes. It could also be due to spectral homogeneity among the classes. This research provides a baseline for future ecological landscape research and for the next management program in the area.

胃肠道癌肿是一类比较常见的恶性肿瘤，其中以胃癌和结肠癌的发病率为多见。早期手术切除癌肿的效果较好。但临床上晚期胃癌和结肠癌病例仍屡见不鲜，常失去手术根治的机会。化疗、放疗是治疗晚期肿瘤的主要手段，但因其毒性反应和使用局限性的限制，效果也不十分理想。基因治疗的研究近期发展很快，但仍处于实验阶段。于不少作者的注意力转向内分泌药治疗。作者重点复习了其中生长抑素（somatostatin，SS）对胃肠道非内分泌肿瘤的作用及其机制。

The HIS is recognised as an essential tool for optimising the management of a health establishment in particular and the health system in general. But it is still very little implemented in hospitals in the South. Open source HIS software, available on the Internet, can be a solution for starting a (HIS) project in these hospitals. A search on the Internet for open source HIS software allowed us to choose MedBoard, the second most popular open source software out of 381, to start an HIS project called PERFORMANCE at the Kara University Hospital in northern Togo. A questionnaire allowed us to assess the level of knowledge of health actors on hospital information systems. The results of this evaluation allowed us to strengthen our proposal. The analysis of the current computer park of the CHU Kara does not allow whatever the functionalities of MedBoard to implement PERFORMANCE at the CHU Kara. Logistics are needed to make PERFORMANCE work. The real difficulty to start and perpetuate HIS project is linked to the human factor.

Objective: To describe the epidemiological, clinical and evolutionary profile of ADPKD in Togo. Methods: A retrospective descriptive transversal study over a period of 8 years (2011-2018) which focused on the analysis of patients’ records diagnosed with ADPKD. The diagnosis of ADPKD was retained on the basis of the ultrasound criteria of PEI. Results: During the study period, 27 patients had polycystic kidney disease with a prevalence of 0.87%. The average age was 51.6 ± 16.4 years. There were 10 men (37%) and 17 women (63%), a sex ratio (M/F) of 0.58. The concept of family cystic kidney disease was found in 6 (22.2%) patients. The clinical presentations were dominated by arterial high blood pressure, abdominal pain and abdominal mass respectively in 77%, 63% and 63% of cases. Five patients (18.5%) had a glomerular filtration rate (GFR) greater than 90 ml/min, 17 (62.9%) had a GFR Conclusion: ADPKD is common in our department. It appears to be associated with a high rate of chronic renal failure.

水资源是人类生存的重要资源之一。水资源不仅是人类生活的必需品,还在人类物种的演化中起着决定性的作用。地下水常作为饮用水源,但由于自然原因或者人为污染原因,地下水往往需要进行处理后才适宜作为饮用水使用。本实验研究了一种稳定浮石曝气生物滤池(BAF)工艺,结合NaOCl氧化-锰砂过滤(MSF)技术,工艺单元进水流速为294.12 mL/min的条件下,分别处理含铁和锰,含铁、锰和氨氮,含铁、锰和有机物同的模拟地下水。模拟配水的铁、锰、氨氮以及腐植酸的进水浓度分别在0.3和6.0 mg/L,0.1和3.0 mg/L,0.5和2.0 mg/L,1.0和6.0 mg/L之间。本文分别研究了曝气生物滤池和锰砂滤柱对不同污染物的去除效果和相互作用,以及NaOCl投加量对污染物的去除效果。结果表明,当原水水质分别为Fe=1.5 mg/L和Mn=0.5mg/L;Fe=1.0mg/L、Mn=0.3mg/L以及NH-N=2.0mg/L,Fe=1mg/L、Mn=0.3mg/L、COD=7.89mg/L和UV254=0.113cm时,曝气生物滤池出水不能满足国家饮用水质标准。当BAF进水中只有Fe和Mn时,Fe的高去除率位于BAF反应器的底部(0-10cm),而Mn的较高的去除效果位于BAF反应器的上部。当BAF进水中同时存在Fe、Mn和氨氮时,Fe和Mn的高去除率位于BAF反应器的00cm,NH-N的高去除率位于BAF反应器的上部。当BAF进水中同时存在Fe、Mn和有机物时,Fe的高去除率位于浮石滤柱的下部(0-30cm),而Mn和有机物的高去除率分别位于浮石滤柱的中部和上部。BAF进水中氨氮浓度的增加对Mn的去除效果的影响大于对Fe的去除效果的影响。进水中有机物的增加对铁、锰、COD和UV254的去除均有影响,亚铁受到轻微影响,UV254受影响最大,其较低的去除率为19.82%;在p H=7.5时亚铁的去除是最理想的;总去除率超过80%,氨氮的较高去除率和较低去除率分别为82%和33%,锰的分别为90%和41.93%,COD的分别为51.64%和31.76%。BAF工艺对亚铁具有良好的去除效果,对锰和氨氮有较好的去除效果,但对COD和UV254的去除率较低。这是因为原水中易生物降解有机物的浓度很低,是一种贫营养水源,不利于微生物的生长和繁殖。溶解氧(DO)对生物去除污染物有一定的影响,当溶解氧不足时,BAF出水氨氮、锰和COD浓度增加,溶解氧沿滤柱由进水到出水方向逐渐下降。BAF浮石滤料对浊度去除效果不好,浊度最高去除率仅为55.4%。氧化剂的投加量是去除污染物的关键因素。NaOCl用量的增加提高了污染物的去除率。NaOCl与Mn和Fe反应形成Mn和Fe的氧化物,其覆盖锰砂材料的表面,使得锰砂滤柱对污染物具有良好的吸收效果。当铁、锰同时存在于原水中时,铁首先会被去除,之后锰再被除去;当铁、锰和氨氮同时存在于原水中时,铁首先会被去除,然后锰和氨氮相继被去除;当铁,锰和有机物同时存在原水中时,铁首先会被去除,其次是锰,最后COD和UV254被去除。锰砂滤柱进水Fe=0.23mg/L,Mn=1.57mg/L时,NaOCl投加量达到5.48mg/L的,就可以完全去除水中的铁和锰。当滤柱进水Fe=0.12mg/L,Mn=0.14mg/L,NH-N=1.34mg/L时,NaOCl投加量达到11.0 mg/L,可使锰砂滤柱出水达标,此时水中Fe和Mn的去除率均为100%,而NH-N的去除率达到77.61%。当进水中同时存在Fe=0.20mg/L,Mn=0.18mg/L,COD=4.08mg/L,UV254=0.083mg/L时,在8.0mg/L的NaOCl投加量下,锰砂滤柱出水达标,水中各污染物的去除率分别为74.13%,95.0%,77.78%,31.64%和23.44%。BAF-NaOCl氧化-MSF组合工艺在水质净化方面具有明显的优点,因为它既可以保证良好的水质,减少消毒副产物的生产还能降低水处理成本,可用于地下水为水源的水处理厂。
