The objective of this study was to describe the prognosis of urinary sphincter disorders during neurological conditions. Methods: This was a six-month analytical study conducted at the neurological unit of the Hôpital national Ignace Deen. Including patients with urinary sphincter disorders following a neurological condition;Chi-square, Fischer, and Student’s t-tests were used for variables with a p value less than 0.10 and then included in a logistic model with a significance level set at 0.05 and a 95% confidence interval. Results: We collected 1081 patients among whom, 324 presented, that is to say a frequency of 30%, which concerned subjects aged 57.3 ± 16.4 years with a slight female predominance 50.3%. Urinary incontinence (80.6%) was associated with complications such as urinary tract infection with a high proportion of cerebral damage (92.3%). HIV infection (P = 0.015), bedsores (P = 0.049), and inhalation pneumonia (P = 0.001) were the main poor prognostic factors. Conclusion: Urinary sphincter disorders are elements of poor prognosis, both vital and functional, concerning elderly subjects with a predominance of urinary incontinence. HIV infection, bedsores, pneumopathy are poor prognostic factors.展开更多

However the presence of this antibody has been associated with paraneoplastic as well as nonparaneoplastic cerebellar degeneration. Most patients with VGCC-antibody-positivity have small cell lung cancer(SCLC). Lambert-Eaton myasthenic syndrome(LEMS)is an autoimmune disease of the presynaptic part of the neuromuscular junction. Its classical clinical triadis proximal muscle weakness, areflexia and autonomic dysfunction. Fifty to sixty percent of LEMS patients have a neoplasia, usually SCLC. The co-occurrence of SCLC and LEMS causes more severe and progressive disease and shorter survival than non-paraneoplastic LEMS. Treatment includes 3,4 diaminopyridine for symptomatic purposes and immunotherapy with prednisolone, azathioprine or intravenous immunoglobulin in patients unresponsive to 3,4 diaminopyridine. Paraneoplastic cerebellar degeneration(PCD) is a syndrome characterized with severe, subacute pancerebellar dysfunction. Serum is positive for VGCC antibody in 41%-44% of patients, usually with the co-occurrence of SCLC. Clinical and electrophysiological features of LEMS are also present in 20%-40% of these patients. Unfortunately, PCD symptoms do not improve with immunotherapy. The role of VGCC antibody in the immunopathogenesis of LEMS is well known whereas its role in PCD is still unclear. All patients presenting with LEMS or PCD must be investigated for SCLC.展开更多

Methods: The patients with acute cerebral infarction who were admitted to our hospital between April 2015 and October 2018 and with the onset time 4.5 hours were selected and divided into the observation group receiving butyphthalide + rt-PA intravenous thrombolysis and the control group receiving rt-PA intravenous thrombolysis by random number table. The differences in DWI parameter apparent diffusion coefficient (ADC), coagulation function indexes and neurological function indexes were compared between the two groups. Results: At 7 and 14 days after treatment, the ADC values of both groups were significantly increased, and the ADC values of the observation group were significantly higher than those of the control group;at 7 days after treatment, the prothrombin time (PT) and activated partial thromboplastin time (APTT) levels in both groups were significantly prolonged whereas fibrinogen (FIB), D-dimer (D-D), platelet activating factor (PAF), P-selectin, von Willebrand factor (vWF), neuron-specific enolase (NSE), S100B protein (S100B), malondialdehyde (MDA) and endothelin-1 (ET-1) contents were significantly decreased, and the APTT and PT levels in the observation group were significantly shorter than those in the control group whereas FIB, D-D, PAF, P-selectin, vWF, NSE, S100B, MDA and ET-1 contents were significantly lower than those in the control group. Conclusion: Butyphthalide + rt-PA intravenous thrombolysis can improve the DWI characteristics, coagulation function and neurological function of patients with acute cerebral infarction.展开更多

The contraindication of codeine in children has changed the management of post tonsillectomy pain. The aim of this study was to assess the management of post tonsillectomy pain in our developing country context. <strong>Methods:</strong> This was a prospective, analytical study lasting 6 months (September 2019-February 2020), carried out in the ENT/CFS department of the Ignace Deen National Hospital. We included in this study all patients who underwent a tonsillectomy in the department during the study period and who agreed to participate in the survey. <strong>Results:</strong> 34 patients were included in our study, i.e. a frequency of 25% of surgical interventions. The mean age of our patients was 18.06 ± 12 years with extremes of 03 years and 45 years. Recurrent hypertrophic tonsillitis with sleep disturbances was the most frequent indication for surgery in our study, at 47.06% (n = 16). We performed an isolated tonsillectomy in 52.9% (n = 18) of cases. Analgesia was multimodal using the WHO Step I and II analgesics in 44.1% (n = 15) and 55.9% (n = 19), respectively. Pain control was satisfactory in all patients. <strong>Conclusion:</strong> The evaluation of post tonsillectomy pain is essential for optimal management. In this indication, multimodal analgesia, involving several levels I and II analgesics, provided satisfactory pain control.展开更多

Methods: The rehabilitation programs of 120 patients in the convalescence of cerebral hemorrhage were reviewed and used to divide them into the control group (n=71) who received conventional rehabilitation training and the observation group (n=49) who received individualized active rehabilitation training. The differences in serum contents of nerve injury-related indexes, pituitary-thyroid axis function indexes, neurotransmitters and so on were compared between the two groups of patients before rehabilitation and after 3 months of rehabilitation. Results:Before rehabilitation, there was no statistically significant difference in serum contents of nerve injury-related indexes, pituitary-thyroid axis function indexes and neurotransmitters between the two groups. After 3 months of rehabilitation, serum nerve injury-related indexes NSE, MBP and S100β contents of observation group were lower than those of control group;serum pituitary-thyroid axis function index FT3 content was higher than that of control group whereas FT4 and TSH contents were lower than those of control group;serum neurotransmitters Dny-A, SP and Glu contents were lower than those of control group whereas GABA content was higher than that of control group. Conclusion: The individualized active rehabilitation training can effectively optimize the neurological function and reduce the nerve injury in patients in the convalescence of cerebral hemorrhage, and can help the recovery of disease.展开更多

Methods: It was a retrospective study of descriptive and analytic type lasting one year six months (18 months) from January 1st, 2016 to June 30th, 2017 which involved patients admitted and hospitalized for cerebral toxoplasmosis in HIV field. Data enter was performed by Epi data 3.1 software and SPSS 21 software for statistical analysis. The threshold of significance was p Results: We observed 87 cases of cerebral toxoplasmosis (CT). The mean age was 38.53 ± 12.16. The clinical signs were mainly infectious syndrome (100%), headache (69.0%), confusion (46.0%) and meningeal syndrome (41.4%). The lethality was 37.9%. Living with a partner (p = 0.007), CD4 at initiation of antiretroviral therapy 3 (p = 0.009), and coma (p = 0.02) were the factors associated with death. Conclusion: This study showed that cerebral toxoplasmosis is associated with very high morbidity and mortality in the Infectious Diseases Department of Donka National Hospital. Living in a relationship, CD4 counts at baseline 3 and coma were independently associated with death. Special attention to these factors associated with infectious resuscitation and primary prevention in patients with a CD4 T lymphocyte count below 200 cells/mm may improve the prognosis of this pathology.展开更多

They were divided into the observation group and the control group. 64 participants stopped taking stimulating drinks such as coffee and alcohol two weeks before the experiment. The sleep quality and depression were measured by the Pittsburgh Sleep Quality Index (PSQI) and Hamilton Depression Scale (HAMD). Degree of depression was examined by brain MRI. Two days later,11C-Raclopril labeled brain dopamine neurotransmitter binding to receptors was scanned by PET/CT. SPSS was used to analyze the correlation between dopamine neurotransmitters and sleep disorders.Results: The HAMD and PSQI scores of the observation group were significantly higher than those of the control group (P<0.05). On PET/CT scans,11C-Raclopride was mostly located in nucleus dorsal caudate putamen, caudate nucleus, and putamen. The dopamine binding ability of nucleus dorsal caudate putamen, caudate nucleus and putamen in the observation group was significantly lower than that in the control group (P<0.05). Pearson correlation analysis showed that the course of disease in the observation group was negatively correlated with nucleus dorsal caudate putamen, caudate nucleus and putamen (r=-0.754, -0.717, -0.728;P<0.05), while the scores of HAMD and PSQI were not correlated with nucleus dorsal caudate putamen, caudate nucleus and putamen (P>0.05).Conclusion: The decrease of dopamine receptor binding in patients with sleep disorders is related to the course of sleep disorders, suggesting that the decrease of dopamine expression and sleep disorders have clinical significance.展开更多

They can affect the central nervous system, the peripheral nervous system or both nervous systems. Objectives: To describe the epidemiological, clinical, paraclinical, therapeutic and evolutive aspects of neurological disorders related to autoimmune diseases. Methods: This was a prospective cohort study. It was carried out from 1 January 2015 to 31 December 2019 (5 years). It focused on patients aged 15 years and above, who were hospitalized or followed as ambulatory patients for neurological disorders related to autoimmune diseases in the neurology department of the university teaching hospital in Brazzaville. Results: Among the 41 patients who fulfilled inclusion criteria, there were 29 (70.73%) women and 12 (29.27%) men. The average age of patients was 38.3 ± 13.8 years. An increase in the frequency of neurological disorders related to autoimmune diseases was observed every year. The main neurological disorders were neuromyelitis optica spectrum disorders (n = 14;34.15%), acute polyradiculoneuropathies (n = 13;31.71%), chronic polyradiculoneuropathies (n = 4;9.75%) and acute disseminated encephalomyelitis (n = 3;7.31%). The treatments administered, which consisted of corticosteroids and immunosuppressive drugs, had significantly improved the vital prognosis and functional status of patients (p = 0.025). Conclusion: In our study population, neurological disorders related to autoimmune diseases are rare. The neurological clinico-pathological entities diagnosed are similar to those reported in the literature. The therapeutic approaches used improve the quality of life of patients.展开更多

However the presence of this antibody has been associated with paraneoplastic as well as nonparaneoplastic cerebellar degeneration. Most patients with VGCC-antibody-positivity have small cell lung cancer(SCLC). Lambert-Eaton myasthenic syndrome(LEMS)is an autoimmune disease of the presynaptic part of the neuromuscular junction. Its classical clinical triadis proximal muscle weakness, areflexia and autonomic dysfunction. Fifty to sixty percent of LEMS patients have a neoplasia, usually SCLC. The co-occurrence of SCLC and LEMS causes more severe and progressive disease and shorter survival than non-paraneoplastic LEMS. Treatment includes 3,4 diaminopyridine for symptomatic purposes and immunotherapy with prednisolone, azathioprine or intravenous immunoglobulin in patients unresponsive to 3,4 diaminopyridine. Paraneoplastic cerebellar degeneration(PCD) is a syndrome characterized with severe, subacute pancerebellar dysfunction. Serum is positive for VGCC antibody in 41%-44% of patients, usually with the co-occurrence of SCLC. Clinical and electrophysiological features of LEMS are also present in 20%-40% of these patients. Unfortunately, PCD symptoms do not improve with immunotherapy. The role of VGCC antibody in the immunopathogenesis of LEMS is well known whereas its role in PCD is still unclear. All patients presenting with LEMS or PCD must be investigated for SCLC.

文摘Objective: To investigate the effects of butyphthalide + alteplase (rt-PA) intravenous thrombolysis on the diffusion-weighted imaging (DWI) characteristics, coagulation function and neurological function in patients with acute cerebral infarction. Methods: The patients with acute cerebral infarction who were admitted to our hospital between April 2015 and October 2018 and with the onset time 4.5 hours were selected and divided into the observation group receiving butyphthalide + rt-PA intravenous thrombolysis and the control group receiving rt-PA intravenous thrombolysis by random number table. The differences in DWI parameter apparent diffusion coefficient (ADC), coagulation function indexes and neurological function indexes were compared between the two groups. Results: At 7 and 14 days after treatment, the ADC values of both groups were significantly increased, and the ADC values of the observation group were significantly higher than those of the control group;at 7 days after treatment, the prothrombin time (PT) and activated partial thromboplastin time (APTT) levels in both groups were significantly prolonged whereas fibrinogen (FIB), D-dimer (D-D), platelet activating factor (PAF), P-selectin, von Willebrand factor (vWF), neuron-specific enolase (NSE), S100B protein (S100B), malondialdehyde (MDA) and endothelin-1 (ET-1) contents were significantly decreased, and the APTT and PT levels in the observation group were significantly shorter than those in the control group whereas FIB, D-D, PAF, P-selectin, vWF, NSE, S100B, MDA and ET-1 contents were significantly lower than those in the control group. Conclusion: Butyphthalide + rt-PA intravenous thrombolysis can improve the DWI characteristics, coagulation function and neurological function of patients with acute cerebral infarction.
文摘Dear editor,After sustaining severe traumatic brain injury(TBI),patients frequently require invasive mechanical ventilation(MV).However,up to 26%of patients require tracheostomy due to failure to wean from the ventilator.[1]The decision of when to perform tracheostomy is important as it balances the risk between avoiding prolonged MV and avoiding risk of tracheostomy.Early predictors for tracheostomy,i.e.,clinical factors when patients first present to an Emergency Department after trauma or when patient fi rst arrive at a regional trauma center,can help clinicians’medical decision-making process.
文摘Objective:To study the differences in the effect of intravenous alteplase thrombolysis and non-thrombolytic therapy on the neurological function in patients with acute cerebral infarction as well as the specific molecular mechanism.Methods:Patients with acute cerebral infarction who were treated in our hospital between April 2013 and May 2016 were selected and randomly divided into two groups, thrombolysis group received intravenous alteplase thrombolysis and non-thrombolysis group received conventional treatment. After treatment, transcranial color Doppler ultrasound was used to assess intracranial blood flow, and serum was collected to detect blood coagulation function indexes, nerve injury indexes and inflammatory stress response indexes.Results:1 week and 2 weeks after treatment, middle cerebral artery Vs, Vd and Vm levels of thrombolysis group were significantly higher than those of non-thrombolysis group;2 weeks after treatment, serum FVIII, VWF, S100β, NSE, GFAP, MBP, UCH-L1, TNF-α, IL-1β, MDA, AOPP and 8-OHdG content of thrombolysis group were significantly lower than those of control group while PT, TT and APTT were significantly higher than those of control group.Conclusion: Intravenous alteplase thrombolysis can improve cerebral blood perfusion and alleviate nerve injury in patients with acute cerebral infarction, and inhibiting blood coagulation process as well as oxidizing and inflammatory reaction is the molecular mechanism for alteplase to achieve therapeutic action.
文摘<strong>Introduction:</strong> Tonsillectomy is described as one of the oldest surgical procedures according to the authors of the surgical treatise (Aulus Amida and Paul of Aegina in the 6th and 7th centuries) found in the Vatican library. The contraindication of codeine in children has changed the management of post tonsillectomy pain. The aim of this study was to assess the management of post tonsillectomy pain in our developing country context. <strong>Methods:</strong> This was a prospective, analytical study lasting 6 months (September 2019-February 2020), carried out in the ENT/CFS department of the Ignace Deen National Hospital. We included in this study all patients who underwent a tonsillectomy in the department during the study period and who agreed to participate in the survey. <strong>Results:</strong> 34 patients were included in our study, i.e. a frequency of 25% of surgical interventions. The mean age of our patients was 18.06 ± 12 years with extremes of 03 years and 45 years. Recurrent hypertrophic tonsillitis with sleep disturbances was the most frequent indication for surgery in our study, at 47.06% (n = 16). We performed an isolated tonsillectomy in 52.9% (n = 18) of cases. Analgesia was multimodal using the WHO Step I and II analgesics in 44.1% (n = 15) and 55.9% (n = 19), respectively. Pain control was satisfactory in all patients. <strong>Conclusion:</strong> The evaluation of post tonsillectomy pain is essential for optimal management. In this indication, multimodal analgesia, involving several levels I and II analgesics, provided satisfactory pain control.

IPA is also extensively used in industry and laboratories as a solvent.
文摘Objective: To explore the value of individualized active rehabilitation training for neurological functional reconstruction in the convalescence of cerebral hemorrhage. Methods: The rehabilitation programs of 120 patients in the convalescence of cerebral hemorrhage were reviewed and used to divide them into the control group (n=71) who received conventional rehabilitation training and the observation group (n=49) who received individualized active rehabilitation training. The differences in serum contents of nerve injury-related indexes, pituitary-thyroid axis function indexes, neurotransmitters and so on were compared between the two groups of patients before rehabilitation and after 3 months of rehabilitation. Results:Before rehabilitation, there was no statistically significant difference in serum contents of nerve injury-related indexes, pituitary-thyroid axis function indexes and neurotransmitters between the two groups. After 3 months of rehabilitation, serum nerve injury-related indexes NSE, MBP and S100β contents of observation group were lower than those of control group;serum pituitary-thyroid axis function index FT3 content was higher than that of control group whereas FT4 and TSH contents were lower than those of control group;serum neurotransmitters Dny-A, SP and Glu contents were lower than those of control group whereas GABA content was higher than that of control group. Conclusion: The individualized active rehabilitation training can effectively optimize the neurological function and reduce the nerve injury in patients in the convalescence of cerebral hemorrhage, and can help the recovery of disease.
文摘Objectives: To identify predictive factors for poor prognosis during cerebral toxoplasmosis at Donka Hospital. Methods: It was a retrospective study of descriptive and analytic type lasting one year six months (18 months) from January 1st, 2016 to June 30th, 2017 which involved patients admitted and hospitalized for cerebral toxoplasmosis in HIV field. Data enter was performed by Epi data 3.1 software and SPSS 21 software for statistical analysis. The threshold of significance was p Results: We observed 87 cases of cerebral toxoplasmosis (CT). The mean age was 38.53 ± 12.16. The clinical signs were mainly infectious syndrome (100%), headache (69.0%), confusion (46.0%) and meningeal syndrome (41.4%). The lethality was 37.9%. Living with a partner (p = 0.007), CD4 at initiation of antiretroviral therapy 3 (p = 0.009), and coma (p = 0.02) were the factors associated with death. Conclusion: This study showed that cerebral toxoplasmosis is associated with very high morbidity and mortality in the Infectious Diseases Department of Donka National Hospital. Living in a relationship, CD4 counts at baseline 3 and coma were independently associated with death. Special attention to these factors associated with infectious resuscitation and primary prevention in patients with a CD4 T lymphocyte count below 200 cells/mm may improve the prognosis of this pathology.
文摘Objective:To explore the effect of dopamine neurotransmitter expression on sleep disorders in neurological inpatients.Methods: Thirty-four patients with sleep disorders and 30 volunteers from February 2018 to November 2018 in the neurology department of our hospital were selected as the study subjects. They were divided into the observation group and the control group. 64 participants stopped taking stimulating drinks such as coffee and alcohol two weeks before the experiment. The sleep quality and depression were measured by the Pittsburgh Sleep Quality Index (PSQI) and Hamilton Depression Scale (HAMD). Degree of depression was examined by brain MRI. Two days later,11C-Raclopril labeled brain dopamine neurotransmitter binding to receptors was scanned by PET/CT. SPSS was used to analyze the correlation between dopamine neurotransmitters and sleep disorders.Results: The HAMD and PSQI scores of the observation group were significantly higher than those of the control group (P<0.05). On PET/CT scans,11C-Raclopride was mostly located in nucleus dorsal caudate putamen, caudate nucleus, and putamen. The dopamine binding ability of nucleus dorsal caudate putamen, caudate nucleus and putamen in the observation group was significantly lower than that in the control group (P<0.05). Pearson correlation analysis showed that the course of disease in the observation group was negatively correlated with nucleus dorsal caudate putamen, caudate nucleus and putamen (r=-0.754, -0.717, -0.728;P<0.05), while the scores of HAMD and PSQI were not correlated with nucleus dorsal caudate putamen, caudate nucleus and putamen (P>0.05).Conclusion: The decrease of dopamine receptor binding in patients with sleep disorders is related to the course of sleep disorders, suggesting that the decrease of dopamine expression and sleep disorders have clinical significance.
文摘Background: Autoimmune diseases, which are among the leading causes of morbidity and mortality in the world, are pathologies caused by a dysfunction of the immune system. They can affect the central nervous system, the peripheral nervous system or both nervous systems. Objectives: To describe the epidemiological, clinical, paraclinical, therapeutic and evolutive aspects of neurological disorders related to autoimmune diseases. Methods: This was a prospective cohort study. It was carried out from 1 January 2015 to 31 December 2019 (5 years). It focused on patients aged 15 years and above, who were hospitalized or followed as ambulatory patients for neurological disorders related to autoimmune diseases in the neurology department of the university teaching hospital in Brazzaville. Results: Among the 41 patients who fulfilled inclusion criteria, there were 29 (70.73%) women and 12 (29.27%) men. The average age of patients was 38.3 ± 13.8 years. An increase in the frequency of neurological disorders related to autoimmune diseases was observed every year. The main neurological disorders were neuromyelitis optica spectrum disorders (n = 14;34.15%), acute polyradiculoneuropathies (n = 13;31.71%), chronic polyradiculoneuropathies (n = 4;9.75%) and acute disseminated encephalomyelitis (n = 3;7.31%). The treatments administered, which consisted of corticosteroids and immunosuppressive drugs, had significantly improved the vital prognosis and functional status of patients (p = 0.025). Conclusion: In our study population, neurological disorders related to autoimmune diseases are rare. The neurological clinico-pathological entities diagnosed are similar to those reported in the literature. The therapeutic approaches used improve the quality of life of patients.
文摘Objective:To study the effect of minimally invasive evacuation of hematoma combined with Xingnaojing therapy on neurological function damage and cytokine level in patients with hypertensive cerebral hemorrhage.Methods:A total of 80 patients with hypertensive cerebral hemorrhage treated in our hospital between June 2010 and September 2015 were selected as the research subjects, the treatment methods and test results were reviewed, and then they were divided into the control group (n=45) who accepted minimally invasive evacuation of hematoma alone and the observation group (n=35) who accepted minimally invasive evacuation of hematoma combined with Xingnaojing therapy. Before and after treatment, cerebral blood flow detector was used to detect cerebral blood flow parameters;ELISA method was used to detect serum levels of neurological function indexes and inflammatory cytokines;high performance liquid chromatograph was used to detect serum neurotransmitter levels. Results: Before treatment, the differences in cerebral blood flow parameters, neurological function indexes, inflammatory cytokines and neurotransmitters were not statistically significant between two groups of patients. After treatment, cerebral blood flow parameters Q and V levels of observation group were higher than those of control group while R level was lower than that of control group;serum NSE, NPY, IL-1β, IL-4, IL-6, TNF-α, Glu and Asp contents of observation group were lower than those of control group while BDNF and Gly contents were higher than those of control group.Conclusion: Minimally invasive evacuation of hematoma combined with Xingnaojing therapy can improve the neurological function and regulate the synthesis of inflammatory cytokines and neurotransmitters in patients with hypertension cerebral hemorrhage.
