Évaluation du risque d’inondation par intégration du SAGA Wetness Index (SAGAWI) et de l’Analyse Hiérarchique des Procédés (AHP) : cas du District Autonome d’Abidjan
Authors: Traoré Kinakpefan Michel 
Published: August 2023

Le District Autonome d’Abidjan (DAA) est en proie à une recrudescence des inondations. Ces évènements hydroclimatiques inhérents à la morphologie du site et à une expansion spatiale non maîtrisée sont susceptibles d’exaspération du fait des effets des changements globaux. Dans une perspective de gestion préventive des crises subséquentes, cette étude a pour objectif d’identifier les sous-espaces du District Autonome d’Abidjan les plus enclins aux risques d’inondation. L’approche cartographique intègre un indice topographique d’humidité en l’occurrence le SAGA Wetness Index et un indice d’imperméabilité des sols généré à partir de la normalisation des facteurs « pente », « sol » et « usage des terres et occupations des sols » à travers l’Analyse Hiérarchique des Procédés (AHP) de Saaty (1984). A l’analyse, la susceptibilité d’occurrence de l’aléa inondation reste importante sur près du quart du territoire. Cette importante inondabilité concerne plus du tiers (36,43 %) du bâti. Le risque élevé d’inondation reste particulièrement l’apanage des espaces fortement anthropisés qui accueillent près de trois habitants du DAA sur quatre (74,20 %). Dans une perspective de gestion anticipative des crises liées à ces évènements pluvieux extrêmes, la carte de l’inondabilité apparait comme un outil important dans la mise en place des systèmes d’alerte précoce.
Art et technique au prisme du phénomène de l’obsolescence
Authors: Guchet Xavier 
Published: August 2023

Certaines œuvres d’art comportent des éléments techniques que l’industrie ne produit plus : il devient alors impossible de remplacer ces éléments lorsqu’ils ne fonctionnent plus, afin de conserver à l’œuvre son intégrité et donc sa signification. Cet épineux problème, qualifié d’obsolescence, affecte-t-il le monde de l’art de façon purement extérieure – comme si ce monde avait à subir des choix (en l’occurrence industriels) qui ne le concernent pas, qui n’ont rien à voir avec le travail et la pensée de l’artiste, qui ne mordent pas sur l’essence même de l’œuvre d’art dans le monde actuel ? L’article soutient au contraire l’idée que le phénomène de l’obsolescence met en question l’essence même du rapport entre l’art et la technique, et qu’il est la conséquence d’une pensée insuffisante de ces rapports. Problème de nature conceptuelle donc, et non de choix économiques stricto sensu.
La restauration de films : une histoire (post-)moderne
Authors: Venturini Simone 
Published: August 2023

Le domaine de la préservation des films se situe aujourd’hui au cœur d’une problématique visant à comprendre et à maîtriser la transition en cours. La restauration de films ne s’est en effet rapprochée que récemment des pratiques de conservation. Dans les années 1980, on s’est ainsi efforcé d’analyser les changements intervenus au niveau du médium lui-même, mais aussi au niveau culturel et symbolique, et les années 1990 ont constitué l’apogée de la réflexion théorique et méthodologique sur la restauration cinématographique. La transition vers le numérique, en revanche, n’a pas provoqué d’évolution significative de la réflexion, mais elle a détourné l’attention vers d’autres aspects de la question. On s’est alors moins intéressé aux méthodologies de restauration qu’aux stratégies de gestion, de diffusion et de présentation. On a aujourd’hui la confirmation que le film constitue une entité ambiguë et ambivalente : d’un côté, il est un bien culturel ; de l’autre, il s’impose comme un élément central des services et des produits offerts par les archives en leur qualité d’entreprises culturelles. De la restauration au sens « noble » du terme, on a abouti, d’un côté, à une approche centrée sur les produits ou assets, et à une gestion de type économique, de l’autre côté, à une approche qui favorise la muséification et soulève des problèmes de conservation. Les relations paradoxales et dialectiques entre la conservation et l’exposition, entre un accès actif ou passif, ne s’épuisent, ne se résolvent et ne se recomposent jamais définitivement ; elles apparaissent au contraire plus que jamais comme le moteur même du système.
Localized Giant Cell Tumor of the Tendon Sheath of the Upper Cervical Spine
Authors: Hu Yu , Chen Min , Richard Seidu A , Huang Siqing 
Published: August 2023

Introduction:
Giant cell tumor of the tendon sheath (GCTTS) is commonly seen in the appendicular skeleton, and rarely arises from the axial skeleton. We describe a rare case of GCTTS in an adolescent in the upper cervical spine.

Case Presentation:
A previously healthy 16-year-old boy presented with a 6-month history of numbness of right upper extremity, and had experienced a neck pain 4 months ago. Spinal MRI demonstrated a small syrinx at C2 level and a well-circumscribed extradural mass with contrast enhancement extending from the posterior arch of C1 to C2. The extradural mass was totally resected, and the syrinx underwent clinical and imaging surveillance.

Discussion:
GCTTS should be considered in the differential diagnosis of the axial skeletal lesion although very rare. Gross-total resection is advocated in GCTTS of the upper cervical spine, and subtotal resection with meticulous lesion monitoring should be performed in unresectable cases.
Evaluation of MR-Tractography Findings in Hemifacial Spasm Patients Injected with Botulinum Neurotoxin
Authors: Çavuş Hakan , İşeri Pervin , Öztürk Onural , Anık Yonca 
Published: August 2023

Background and Introduction:
Botulinum neurotoxin (BoNT) is a potent biological toxin extracted from Clostridium Botulinum bacteria. BoNT injection is mainly used for medical purposes; it is frequently used for cosmetic purposes as well. The hypothesis that frequent application of this treatment modality may also affect the central nervous system constitutes the subject of our study.

Objective:
We aimed to demonstrate the possible central effects of BoNT in hemifacial spasm patients.

Methods and Materials:
Diffusion tensor imaging was used for this study. Patients were divided into two groups, and the measured values for each determined bilateral neuroanatomic region were compared within the relevant group.

Results:
Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values were found to be closer to the pathological values in the right motor cortex and in the left internal capsule areas of the patients who were injected with BoNT into the left side, in the left motor cortex area of the patients who were injected with BoNT into the right side. No significant changes were detected in other regions.

Conclusion:
Botulinum neurotoxin administration in patients with hemifacial spasms may cause some changes in the central nervous system as well as peripheral effects. In the case of similar studies supporting pathological changes, BoNT treatment modalities or appropriate indications may be reviewed, and regulation on excessive cosmetic use may be in question.
Clinical Study of High-Resolution C-Arm CT in Mechanical Recanalization and Stent Implantation for Chronic Cerebral Artery Occlusion
Authors: Li Teng-Fei , Shi Cheng-Cheng , Ma Ji , Fu Pei-Ji , Zhu Ming , Ren Jian-Zhuang , Han Xin-Wei 
Published: August 2023

Background:
In recent years, among patients with chronic cerebral artery occlusion, recanalization can be achieved by an endovascular operation. However, complications and restenosis rates remain high.

Objective:
To evaluate the utility of high-resolution C-arm CT (Dyna micro-CT) for stent placement in patients with chronic cerebral artery occlusion.

Methods and Materials:
We retrospectively reviewed the clinical data of 27 patients with chronic cerebral artery occlusion who underwent mechanical recanalization and stent implantation. Images were reconstructed using conventional C-arm CT (Dyna CT) and Dyna micro-CT. Whether the stent was fully expanded and image quality was evaluated. Follow-up assessments included clinical and angiographic outcomes and complications.

Results:
Twenty-two patients successfully underwent stenting (22 stents; 14 cases: Neuroform EZ; eight cases: Enterprise); stenting failed in five patients. Compared to Dyna CT, Dyna micro-CT afforded improved visualization of the stent structure, providing significantly improved image quality (P < 0.05). In seven patients, the stent under-expanded and dilatation was performed; thereafter, stent malapposition improved. One patient experienced sudden headache 22 hours after the procedure; CT showed intraparenchymal hemorrhage. The remaining 21 patients did not have acute thrombosis or bleeding complications and were followed up by imaging for 3-6 months. In three patients, digital subtraction angiography showed mild in-stent stenosis.

Conclusions:
High-resolution C-arm CT can improve visualization of stent structures in chronic cerebral artery occlusion, making it easy to determine the extent of stent deployment and potentially reduce complications and stent restenosis.
Association Between Stroke Characteristics and Post-Stroke Fatigue
Authors: Shu Jun , Ren Yiqing , Liu Guidong , Wei Wenshi 
Published: August 2023

Background:
Post-stroke fatigue (PSF), a highly distressing symptom, could exert an influence on the quality of life of stroke survivors. A previous meta-analysis reported that PSF was associated with mood disturbances such as depressive symptoms and anxiety. However, the association between stroke characteristics (stroke type and location) and PSF remains unclear.

Objective:
We performed a meta-analysis to study the association between stroke characteristics and PSF.

Material and Methods:
We conducted a search of electronic databases (PubMed, Web of Science, Cochrane Library) from the inception of all databases up to July 9, 2019. The quality of eligible articles was evaluated. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were applied to represent the combined effect value of each study.

Results:
Eight eligible studies including a total of 1816 stoke patients were identified. Three studies discussed the association between stroke type and PSF, and five studies investigated the relationship between stroke location and PSF. The results demonstrated PSF had a strong correlation with stroke type (OR = 2.42, 95% CI = [1.27, 4.61], P = 0.007) but was not relevant to stroke location, indicating that PSF was a complex, heterogeneous syndrome and that stroke characteristics may play only a very small role in the risk of developing PSF.

Conclusions:
Our meta-analysis indicated that PSF was closely relevant to stroke type and had no significant relationship with stroke location. However, the findings should be interpreted cautiously. Thus, we suggest an updated meta-analysis on this subject when more comprehensive studies that explore the above issue are available.

Authors: A. Sousa Luis Henrique , Costa Caroline de O. , Novak Eduardo M. , Giostri Giana S. 
Published: August 2023

Background:
Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment. One of the most devastating complications is complex regional pain syndrome.

Objectivities:
The aim of this study was to systematically analyze available evidence about complex regional pain syndrome after carpal tunnel syndrome surgery (CTSS), its risks, associated factors, and treatments.

Material and Methods:
Research conducted from 1962 through December 31, 2018, in the following databases: PubMed, Web of Science, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials. The quality assessment of the methodology followed the definitions by the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence. The GRADE system (Grades of Recommendation, Assessment, Development, and Evaluation) was applied to evaluate the efficacy of the stellate ganglion block, one of the most cited and recurrent treatments.

Results:
Of the 246 studies retrieved, 44 articles were included. Concerning patients' gender, we identified a ratio of 5 females: 3 males. The mean age for women was 57.79, a standard deviation of 14.96, and for men 60.75, a standard deviation of 9.4. Considering the total of primary publications of CTSS outcomes, the accumulated incidence reached the maximum of 0.15 CRPS after CTSS patients/CTSS patients. The known risk factors for CRPS after CTSS: female gender, from the fifth decade of life, tourniquet time, immobilization and surgery on dominant hand.

Conclusion:
CRPS affects 2-5% of people undergoing CTSS. Its diagnosis is still a challenge and its risk factors are unclear, although it seems more likely to affect women, in the dominant hand. The most used treatments include physiotherapy and stellate ganglion block. Most patients show improvement of symptoms within one year. Further clinical trials comparing treatment modalities are required.

Published: August 2023

Background:
COVID-19 causes a hypercoagulable state leading to thrombosis. Many of these thrombotic complications occur in those with severe disease and late in the disease course. COVID-19 has recently been associated with cerebral venous thrombosis (CVT).

Objective:
To study the onset of CVT in relation to COVID-19 and compare their characteristics and outcomes with non-COVID CVT patients admitted during the same period.

Materials and Methods:
This multicentric, retrospective study conducted between April 4 and October 15, 2020, included adult patients with CVT who were positive for the SARS-CoV-2 virus and compared them with CVT patients who were negative for the SARS-CoV-2 virus hospitalized during the same period. We studied their clinical profile, risk factors for CVT, and markers of COVID coagulopathy, imaging characteristics, and factors influencing their outcomes.

Results:
We included 18 COVID-19-infected patients and compared them with 43 non-COVID-19 CVT patients. Fourteen patients in the COVID-19 group presented with CVT without the other typical features of COVID-19. Thirteen patients had non-severe COVID-19 disease. Twelve patients had a good outcome (mRS ≤2). Mortality and disability outcomes were not significantly different between the two groups.

Conclusion:
Our study suggests a possible association between COVID-19 and CVT. CVT can be the presenting manifestation of an underlying COVID-19, occurring early in the course of COVID-19 and even in those with mild disease. Patients with worse GCS on admission, abnormal HRCT chest, severe COVID-19, and need for invasive ventilation had a poor outcome.

Authors: Vignesh S , Prasad Surya N. , Singh Vivek , Phadke Rajendra V. , Balaguruswamy Madan M. , Udiya Alok , Shetty Gurucharan S , Dhull Vedita 
Published: August 2023

Background:
Wide-neck intracranial aneurysms need additional devices like balloons or stent for management. Balloon-assisted coiling has evolved both with interventionalist experience and device modifications.

Objective:
We discussed our experience, evolution, and complications with this novel technique.

Materials and Methods:
Data of 2014–2019 was retrospectively reviewed for type of balloon used along with complications in intracranial aneurysm coiling. Two hundred five aneurysms were detected in 188 patients, of which balloon-assisted coiling was planned for 198 aneurysms. Both single and double-lumen balloons were used. Aneurysms were divided into bifurcation and sidewall aneurysms. The complications were compared between bifurcation and sidewall aneurysms, and between single and double lumen balloons.

Results:
Balloon-assisted coiling was planned for 198 aneurysms but successfully done for 195 (98.5%) cases. Single-lumen balloons were used in 56 aneurysms (28.3%), and double-lumen balloons were used in 142 cases (71.7%). Procedural thromboembolism within parent vessel was seen in 28 cases (14.1%); however symptomatic were encountered in 5 cases (2.5%). Intraprocedural rupture of the aneurysmal sac was seen in 9 cases (4.5%). The procedure-related mortality in our series was 1.6% (3/188 patients), and morbidity was 4.3% (8/188 patients). The complications among bifurcation and sidewall aneurysms compared between single- and double-lumen balloons showed a greater number of symptomatic thromboembolic complications in sidewall aneurysms with the use of single lumen balloons.

Conclusions:
There are significant symptomatic thromboembolic complications in sidewall aneurysms with the use of single-lumen balloons which decreased as interventionalist experience evolved and better hardware developed.
Endovascular Thrombectomy Eligibility in the 0-24-Hour Time Window at a Large Academic Center in India
Authors: Vibha Deepti , Misra Shubham , Desai Shashvat M , Prasad Kameshwar , Srivastava Achal K , Pandit Awadh K , Jadhav Ashutosh P 
Published: August 2023

Background:
The data regarding patients eligible for endovascular thrombectomy (EVT), especially in the developing world is lacking.

Objective:
To determine the proportion of patients with acute ischemic stroke (AIS) who are eligible for EVT in the 0-24-h time window.

Materials and Methods:
We performed a retrospective cohort study using prospectively collected AIS data between July 2017 and September 2019. Demographic, clinical, and management information were analyzed. EVT eligibility was explored using the following criteria: National Institutes of Health Stroke Scale (NIHSS) score ≥6, presence of anterior circulation large-vessel occlusion (ACLVO), Alberta stroke program early Computerized Tomography score (ASPECTS) ≥6, baseline modified Rankin Scale (mRS) score 0–2, and within 24 h of time last seen well (TLSW). EVT-eligible patients were further evaluated for in-hospital course and outcomes.

Results:
In the study period of 27 months, there were 221 patients with AIS who presented within 24 h. The mean age of the patients was 54.4 (16.0) years and 66.1% (146) were males. A majority (61.5% [136/221]) arrived within 6 h of TLSW. Of these, 81.6% (111/136) presented in the time window for thrombolysis (0–4.5 h). The patients with NIHSS ≥6 and ACLVO constituted 41.2% (91/221) of the patients. AIS eligible for EVT constituted 19.5% (43/221) of the patients.

Conclusion:
In our study, the proportion of AIS eligible for endovascular thrombectomy was comparable to the developed world. These data predict a large potential for the late-window EVT in India.

Authors: Machin Abdulloh , Divamillenia Dinda , Fatimah Nurmawati , Susilo Imam , Purwanto D Agus , Subadi Imam , Sugianto Paulus , Hamdan Muhammad , Pratiwi O Galuh , Fauziah Dyah , Izzawa Kenia 
Published: August 2023

Background:
Stroke is a neurological deficit due to vascular disorders. Microglia are the first line of defense against brain injury. Anti-inflammatory cytokines activate M2 microglia, which upregulate CD206. EGCG is abundant in green tea, which has an anti-inflammatory effect.

Objective:
To know the effect of green tea with its active compound EGCG on CD206 expression.

Settings and Design:
True experimental trial design.

Material and Methods:

Rattus Novergicus were divided into six groups: a negative control group (Sham), a positive control group (P0), MCAO mice given 10 mg/kg BW EGCG (P1), 20 mg/kg BW EGCG (P2), 30 mg/kg BW EGCG (P3), and 30 mg/kg BW standardized green tea extract (P4). CD206 expression was measured using immunohistochemistry and scored according to the Allred scoring guidelines.

Statistical Analysis Used:
Descriptive test, Levine test, Kolmogorov–Smirnoff test, Independent sample t test, Pearson correlation test

Results:
We discovered that there is a significant difference in CD206 expression between the Sham and P0 groups (P < 0.05). In addition, there are significant differences in expression between the sham group and the other two groups (P1 and P2) (P < 0.05). Furthermore, when we compared the P0 group with each treatment group, we found that CD206 expression between P0–P2, P0–P3, P0–P4 are significantly different. There is a significant correlation between green tea with its active compound EGCG and CD206 expression enhancement. The correlation is positive.

Conclusions:
Green tea with EGCG active compound increases CD206 expression as an M2 marker in the Rattus norvegicus with MCAO model.

Published: August 2023

Background:
The surgical skill practice in neurosurgery is being compromised in the recent past owing to the duty time constraint, patient safety concerns, and medico-legal issues. Surgical practice outside the operating room is essential to enhance a resident's operative skills and to gain confidence.

Objective:
To discuss the experience of establishing an 'in-house neurosurgery skills laboratory' and various training sessions conducted with cadaveric and non-cadaveric simulation modules.

Methods:
A skills laboratory was set up in the existing resident teaching hall with nine workstations. Each station has been equipped with an operating table, surgeon's chair, basic microscope, endoscope, high-speed drill system, and a suction machine. Vascular anastomosis, high-speed drilling, and basic neuroendoscopy were planned on low-cost non-cadaveric modules. Craniotomy and various surgical approaches were designed on cadaveric modules obtained from the anatomy department.

Result:
A total of 18 residents in divided groups during their initial three semesters had participated in the non-cadaveric simulation courses. Twenty-six residents had participated and 12 sessions were conducted on the cadaveric modules. Three workshops were conducted and 20 residents and faculty members from five other institutions had participated in the cadaveric hands-on training session.

Conclusion:
A well-equipped skills laboratory provides an opportunity for the residents to acquire operative expertise in a similar atmosphere to that of the operating theater. A structured program comprising various operative practice sessions should be incorporated into the resident training program.
