Abstract: Aim: To evaluate the anesthetic management of neurosurgical patients in University Hospital of Brazzaville. Materials and methods: We performed a transversal and descriptive study during the period from January to June 2015 into operating room of the University Hospital of Brazzaville. 60 cases of anesthesia have been analyzed. Results: The neurosurgery represented 2.88% of the activity of the operating room in University Hospital of Brazzaville. The average age was 44.7 ± 18.36 years old. The sex ratio was 1.07. The scheduled interventions have concerned 83.4% of cases. Surgical indications were concerned the spine degenerative disease and spinal trauma in 40% and 18.3% of cases respectively. The patients classified ASA I and II were most represented in 40% and 46.7% of cases respectively. General anesthesia was used in 98.4% of cases. The peroperative complications were represented by arterial hypotension (31.7%), hemorrhage (11.7%), bradycardia (5%), difficult intubation (3.3%) and one case of peroperative cardiac arrest. The blood transfusion rate was 18.7%. The stay in ICU concerned 8.3% of the cases. We recorded three cases (5%) of death in our series. Conclusion: The neuroanesthesia knows an evolution in our country because of increasing number of neurosurgeons; it’s necessary to train medical staff in her practice.

The aim of this study was to evaluate the medical management of traumatic brain injury. We performed a retrospective and descriptive study during the period from 1st January 2014 to 31st December 2015 (24 months), into the surgical department of the University Hospital of Brazzaville. 167 cases of non-operated traumatized brain have been identified. The average age was 29.84 years. The sex ratio was 8.82. Accidents on public roads were responsible for injury in 88.2% of the cases. 46.71% of patients had a moderate traumatic brain injury while 10.18% had a severe traumatic brain injury. Radiological evaluation was highlighted for the brain contusion in 52.09% of the cases. Tracheal intubation and ventilation were completed only in 6 out of the 17 cases of severe traumatic brain injury. Prevention of post-traumatic seizure was performed with the use of phenobarbital or sodium valproate. Mannitol was used for its osmotic properties. The outcome was favorable in 55.68% of the cases. The most common complications were pulmonary infections, persistent neurological disorders, urinary infection and hyponatremia. Mortality was recorded at 13.77%. Nonsurgical management of traumatic brain injury involves an expansion of the ventilatory assistance indication at all severe traumatic brain injuries, the fight against infectious complications and ionic monitoring.

Abstract: Aim: To describe the epidemiological aspects of the patients who died in polyvalent intensive care unit at University Hospital of Brazzaville. Materials and Methods: This was a retrospective, cross-sectional study carried out in intensive care unit of University Hospital of Brazzaville, during period from January 2013 to December 2014. All patients who died at the unit regardless of age or sex were included. The parameters studied were age, sex, origin, reason for admission, causes of death, time of death, and length of hospitalization. Data were treated in Excel 2010 and Epi info 2007. Results: During the study period, 419 deaths out of 1121 admissions were recorded, representing a mortality rate of 37.4%. The average age was 46.2 ± 19.7 years with extremes ranging from 14 months to 90 years. The sex ratio was 0.9. Most of the deceased patients came from medical emergencies in 37.6% of the cases. Infectious (17.9%) and neurological (17.4%) pathologies were the most likely to cause death followed by cardiovascular pathologies (12.2%). Causes of death were dominated by severe sepsis and septic shock with 93.4% of infectious pathologies and stroke in 80.8% of neurological pathologies. In 42.3% of cases, the death occurred in the 8:00 p.m. to 6:00 a.m. time period. The average length of hospitalization for the deceased patients was 1.4 ± 0.5 days. All parameters studied significantly associated with mortality (p < 0.05). Conclusion: The mortality rate of patients admitted to the polyvalent intensive care unit at University Hospital of Brazzaville was high at 37.4%. Most of these patients were aged 40 years and older, male, with infectious and/or neurological pathologies. All deaths occurred within 48 hours of admission.

Abstract: The aim of this study was to evaluate socio-demographic profile of adults admitted in emergency for Traumatic Brain Injury (TBI) at the University Hospital of Brazzaville in the Republic of Congo. We performed a prospective study within a period of six months, into the surgical unit of the emergency department of the University Hospital of Brazzaville. A total of 2617 patients were recorded, among which 268 cases were TBI (10.25%) where 142 cases were sampled in our series. The average age was 36.7 ± 16.6 years. The sex ratio was 6.1. The TBI was mainly due to road accident in 121 cases (85.2%) described as follows: motorcycle accident about 48 cases (39.7%) and the pedestrian’s injuries about 42 (34.8%). In the majority of the cases, cautions were not taken by the drivers; during the case of the motorcycle accident, about 97.9% of the riders did not wear a helmet. The TBI remains a growing public health concern in the low-income countries, like in Africa. Measurements on the road traffic regulation are to be strengthened to reduce the growth of this silent epidemic.

The association between stroke and meningioma is rarely reported in the data. In most etiology classification, there is no compressive cause. The association between meningioma and stroke is increasingly reported. We report a case of 52-year-old woman, previously healthy, presented with sudden right hemiplegia with some transient mood disorders. The CT-scan revealed acute left anterior cerebral artery infarction associated with fronto-basale meningioma infiltrating both anterior cerebral arteries. She was treated by corticosteroid and rehabilitation, with partial recovery. No stroke prevention was used before surgical treatment.

This study was aimed to determine the extent to which Prosopis species had invaded four settlements (Bokspits, Rappelspan, Vaalhoek and Struizendam) located in the Kgalagadi Desert south west of Botswana, investigate the perceptions of the communities about the existence of the species in their environment and assess possible control options for the spread of Prosopis plants in the area. Prosopis plants were sampled in 42 quadrats of 625 m2 along a 70 km Prosopis invasion gradient from Struizendam to Rappelspan. Using the Global Positioning System (GPS), the locations of all quadrats were established. The distribution map of Prosopis plants was produced using ArcGIS 9.2 (ESRI Inc.). Questionnaire survey and focused group discussions were used to collect data on the perceptions of rural communities about the species. A total of 342 respondents comprising 139 males and 203 females were interviewed, and four focussed group discussions were conducted. The results indicated that the invasion of Prosopis species was prominent in and around settlements suggesting that anthropogenic activities had a significant role in the spread of Prosopis plants in the area. The perceptions of rural

Anomalous diffusion due to hindering by mobile obstacles undergoing Brownian motion or Orstein-Ulhenbeck processes
Hugues Berry,Hugues Chaté
Quantitative Biology , 2011,
Abstract: In vivo measurements of the passive movements of biomolecules or vesicles in cells consistently report ''anomalous diffusion'', where mean-squared displacements scale as a power law of time with exponent $\alpha< 1$ (subdiffusion). While the detailed mechanisms causing such behaviors are not always elucidated, movement hindrance by obstacles is often invoked. However, our understanding of how hindered diffusion leads to subdiffusion is based on diffusion amidst randomly-located \textit{immobile} obstacles. Here, we have used Monte-Carlo simulations to investigate transient subdiffusion due to \textit{mobile} obstacles with various modes of mobility. Our simulations confirm that the anomalous regimes rapidly disappear when the obstacles move by Brownian motion. By contrast, mobile obstacles with more confined displacements, e.g. Orstein-Ulhenbeck motion, are shown to preserve subdiffusive regimes. The mean-squared displacement of tracked protein displays convincing power-laws with anomalous exponent $\alpha$ that varies with the density of OU obstacles or the relaxation time-scale of the OU process. In particular, some of the values we observed are significantly below the universal value predicted for immobile obstacles in 2d. Therefore, our results show that subdiffusion due to mobile obstacles with OU-type of motion may account for the large variation range exhibited by experimental measurements in living cells and may explain that some experimental estimates are below the universal value predicted for immobile obstacles.
