This results in reduced blood flow and oxygen to the brain, leading to progressive symptoms and potential complications. The underlying pathophysiological mechanism remains elucidated. However, recent studies have highlighted numerous etiologic factors: abnormal immune complex responses, susceptibility genes, branched-chain amino acids, antibodies, heritable diseases, and acquired diseases, which may be the great potential triggers for the development of moyamoya disease. Its clinical presentation has varying degrees from transient asymptomatic events to significant neurological deficits. Moyamoya disease (MMD) shows different patterns in children and adults. Children with MMD are more susceptible to ischemic events due to decreased blood flow to the brain. Conversely, adults with MMD are more prone to hemorrhagic events involving brain bleeding. Children with MMD may experience a range of symptoms including motor impairments, sensory issues, seizures, headaches, dizziness, cognitive delays, or ongoing neurological problems. Although adults may present with similar clinical symptoms as children, they are more prone to experiencing sudden onset intraventricular, subarachnoid, or intracerebral hemorrhages. One of the challenges in moyamoya disease is the potential for misdiagnosis or delayed diagnosis, particularly when physicians fail to consider MMD as a possible cause in stroke patients. This review aims to provide a comprehensive overview of recent global studies on the pathophysiology of MMD, along with advancements in its management. Additionally, the review will delve into various surgical treatment options for MMD, as well as its rare occurrence alongside atrioventricular malformations. Exciting prospects include the use of autologous bone marrow transplant and the potential role of Connexin 43 protein treatment in the development of moyamoya disease.展开更多

METHODS: This is a prospective observational study of all adult patients admitted with acute mechanical bowel obstruction between 2001 and 2002. RESULTS: Of the 150 consecutive patients included in the study, 114 (76%) presented with small bowel and 36 (24%) with large bowel obstruction. Absence of passage of flatus (90%) and/or feces (80.6%) and abdominal distension (65.3%) were the most common symptoms and physical finding, respectively. Adhesions (64.8%), incarcerated hernias (14.8%), and large bowel cancer (13.4%) were the most frequent causes of obstruction. Eighty-eight patients (58.7%) were treated conservatively and 62 (41.3%) were operated (29 on the first day). Bowel ischemia was found in 21 cases (14%), necrosis in 14 (9.3%), and perforation in 8 (5.3%). Hernias, large bowel cancer, and adhesions were the most frequent causes of bowel ischemia (57.2%, 19.1%, 14.3%), necrosis (42.8%, 21.4%, 21.4%), and perforation (50%, 25%, 25%). A significantly higher risk of strangulation was noticed in incarcerated hernias than all the other obstruction causes. CONCLUSION: Absence of passage of flatus and/or feces and abdominal distension are the most common symptoms and physical finding of patients with acute mechanical bowel obstruction, respectively. Adhesions, hernias, and large bowel cancer are the most commoncauses of obstruction, as well as of bowel ischemia, necrosis, and perforation. Although an important proportion of these patients can be nonoperatively treated, a substantial portion requires immediate operation. Great caution should be taken for the treatment of these patients since the incidence of bowel ischemia, necrosis, and perforation is significantly high.展开更多

The aim of our study was to study the epidemiological, clinical and etiological aspects of hepatomegaly in the hepato-gastroenterology department (HGE) of the Gabriel Touré university hospital. This was a cross-sectional study that took place from September 2021 to October 2022 in the department. All patients aged 18 years and older with hepatomegaly, hospitalized or examined by physicians were included. We collected 100 cases of hepatomegaly, representing 3.7% of 2661 patients examined or hospitalized in the HGE department during the study period. These patients had a mean age was 46.7 ± 16.10 years with extremes of 18 and 76 years. The sex ratio was 2.7. Jaundice was the most commonly reported history with a frequency of 26%. Pertaining to patients’ lifestyle, alcohol consumption was the most common feature with 6%. The most common associated clinical signs were jaundice, ascites, and edema of the lower limbs. Painful hepatomegaly (86%), with a sharp lower edge (74%), a firm consistency (69%), and an irregular surface (52%) was frequently observed. Cytolysis (75.5%), increased alphafetoprotein levels (70%), microcytic anemia (37%), hyperleukocytosis (54.3%), and biological hepatocellular insufficiency syndrome (low albumin with 30.4%, high bilirubinemia with 61.2% and low platelets with 33.9%) were the most common observed laboratory abnormalities. Hepatitis B virus markers (61%) were the most frequently found in the study patients. At ultrasound examination, heterogeneous hepatomegaly was observed in 87.3% of the patients. Esophageal varices (43.1%) were more commonly seen than other varices during upper gastrointestinal endoscopy. The dominant etiology was hepatocellular carcinoma on cirrhosis with 66% followed by cirrhosis. Conclusion: Painful hepatomegaly was quite frequently in our urban setting hospital with several etiologies. HCC was the most common etiology, therefore measures to prevent it in the community need to be established by the concerned stakeholders to improve adult population health in Bamako.展开更多

Methodology: This was a retrospective study focusing on patients with an eyelid wound, over a 10-year period from 2012 to 2021. We collected and analyzed the data using Excel. Results: The frequency of eyelid wounds was 0.1%. The average age of our patients was 19.38 years with a range of 1 and 62 years. The sex ratio was 3.7. Eighty-one percent of patients lived in Dakar. Fifty-seven percent (57%) of patients consulted less than 24 hours after the trauma and 7% of patients on D1. The circumstances were brawls (11%), domestic accidents (9%), road accidents (6%), and work accidents (6%). We noted 1 case of dog bite. Thirteen patients presented with post-traumatic decreased visual acuity. Involvement of the isolated upper eyelid was noted in 40% of cases and both eyelids in 15% of cases. Involvement of the lacrimal ducts was noted in 17% of cases, and that of the free edge in 21% of cases. Eyelid wounds were associated with eyeball damage in 21% of cases. Various associated lesions were observed. Ninety-one percent of patients received surgical treatment. Three cases of superinfections, 1 case of conjunctival granuloma and 1 case of phthysis of the eyeball with postoperative retinal detachment were noted. Conclusion: Eyelid sores are relatively common in our context. They require rapid surgical treatment in order to preserve the functional and aesthetic prognosis. .展开更多

This study was undertaken to investigate the clinical manifestations of patients with chronic pancreatitis at our hospital. METHODS: The data of the patients with CP who had been treated at our hospital between 1997 and 2004 were analyzed. RESULTS: The major symptoms of the patients with CP were abdominal pain, dyspepsia, loss of weight, diabetes mellitus, pancreatic pseudocyst, steatorrhea, and calcification. Biliary diseases were found to be the first cause of CP in this study; but alcohol abuse was the major cause of CP in men and biliary diseases were the first etiological factors for CP in women. The etiological difference of constituent ratio between men and women was related to alcohol comsumption (P<0.01). CONCLUSIONS: During the past 8 years, biliary diseases have been the major etiological factors for CP, but their constituent ratio is decreasing, and the constituent ratio of alcohol abuse is increasing gradually. Alcohol tends to replace biliary diseases as the primary etiological factor for CP.展开更多

Despite the fact that the etiology of this disease has beenunknown so far, there has been a considerable body of scientific evidence that can reveal the clinical and laboratory signs of PBC and the individual components of its pathogenesis and elaborate diagnostic criteria for the disease and its symptomatic therapy. Deficiencies in autoimmune tolerance are critical factors for the initiation and perpetuation of the disease. The purpose of this review is to summarize the data available in the literature and the author's findings on clinical and laboratory criteria for the diagnosis of PBC. This review describes the major clinical manifestations of the disease and the mechanisms of its development. It presents the immunological, biochemical, and morphological signs of PBC and their significance for its diagnosis. A great deal of novel scientific evidence for the problem of PBC has been accumulated. However, the inadequate efficiency of therapy for the disease lends impetus to the quest for its etiological factors and to further investigations of its pathogenetic mechanisms and, on this basis, to searches for new methods for its early diagnosis.展开更多

In consequence, the number of minors taking part in randomized controlled clinical trials (RCTs) is likely to increase. Clinical trials in minors require a complex methodological design, a careful consideration of risks and benefits and a high level of ethical reflection. Unfortunately, as to the quality of clinical trials and their publications in minors little is known. Therefore, we assessed published reports of randomized, controlled clinical trials in minors, focusing on a common disease (asthma) and a defined spectrum of lifethreatening diseases (malignant diseases). Method: In an exploratory design, we scanned the publications for methodological aspects as well as indicators of ethical soundness, e.g., statements that informed consent had been obtained before the start of the trial or that a Data and Safety Monitoring Board ensured the patients’ safety during the trial. We also looked for passages reflecting the debate on equipoise or other forms of weighing risks and benefits. Results: We found that many of these aspects, which according to the scientific literature and generally acknowledged guidelines are essential to ensure good-quality trials and trial reports, were not considered in the publications analyzed. Conclusion: Therefore, we call for a more transparent and consistent presentation of the trials, especially of safety aspects, relying on a more critical and transparent ethical reflection.展开更多

The difficulty lies in finding the etiology. Objective: To determine the prevalence and clinical profiles of non-traumatic Coma at the Centre Hospitalier Universitaire Pédiatrique de Bangui (CHUPB). Methodology: This was a descriptive and analytical cross-sectional study conducted between January 1 and June 31, 2021, at CHUPB. Children aged 1 month to 15 years, admitted to the emergency room with a Glasgow score less than or equal to 8 without any traumatism were included. The variables studied were sociodemographic, clinical and paraclinical. Data were entered and analyzed using SPSS 20.0 statistical software. The statistical test used was Pearson’s chi<sup>2</sup>, any p-value Results: Of 8551 children hospitalized during the study period, 370 were hospitalized for non-traumatic coma: 4.32%. They were divided into 57.5% (n = 213) boys and 42.44% (n = 157) girls, giving a sex ratio of 1.35. Their mean age was 35.95 ± 27.21 months. Children aged 1 to 24 months represented 54.59% (n = 202) of cases. The mean time to the consultation was 2.91 days ± 1.8. Fever 86.48% (n = 320) and convulsions 80% (n = 296) were the main reasons for consultation. Coma stages II - III and IV represented 52.44% (n = 194), 42.97% (n = 159) and 4.59% (n = 17) respectively. Neuromalaria (29.72%;n = 110), meningitis-meningoencephalitis-encephalitis (30%;n = 111), sepsis (19.72%;n = 73) and acidosis Coma (5.40%;n = 20) were the main etiologies. Conclusion: Non-traumatic coma is common at CHUPB. Infections were the main etiology, particularly cerebral malaria. The reduction of its frequency requires, among others, the strengthening of the national monitoring malaria program. The strengthening of the technical platform for a good etiological diagnosis constitutes the other axis of prevention.展开更多

文摘Summary: Hepatomegaly is one of the clinical signs commonly encountered in chronic liver disease. The aim of our study was to study the epidemiological, clinical and etiological aspects of hepatomegaly in the hepato-gastroenterology department (HGE) of the Gabriel Touré university hospital. This was a cross-sectional study that took place from September 2021 to October 2022 in the department. All patients aged 18 years and older with hepatomegaly, hospitalized or examined by physicians were included. We collected 100 cases of hepatomegaly, representing 3.7% of 2661 patients examined or hospitalized in the HGE department during the study period. These patients had a mean age was 46.7 ± 16.10 years with extremes of 18 and 76 years. The sex ratio was 2.7. Jaundice was the most commonly reported history with a frequency of 26%. Pertaining to patients’ lifestyle, alcohol consumption was the most common feature with 6%. The most common associated clinical signs were jaundice, ascites, and edema of the lower limbs. Painful hepatomegaly (86%), with a sharp lower edge (74%), a firm consistency (69%), and an irregular surface (52%) was frequently observed. Cytolysis (75.5%), increased alphafetoprotein levels (70%), microcytic anemia (37%), hyperleukocytosis (54.3%), and biological hepatocellular insufficiency syndrome (low albumin with 30.4%, high bilirubinemia with 61.2% and low platelets with 33.9%) were the most common observed laboratory abnormalities. Hepatitis B virus markers (61%) were the most frequently found in the study patients. At ultrasound examination, heterogeneous hepatomegaly was observed in 87.3% of the patients. Esophageal varices (43.1%) were more commonly seen than other varices during upper gastrointestinal endoscopy. The dominant etiology was hepatocellular carcinoma on cirrhosis with 66% followed by cirrhosis. Conclusion: Painful hepatomegaly was quite frequently in our urban setting hospital with several etiologies. HCC was the most common etiology, therefore measures to prevent it in the community need to be established by the concerned stakeholders to improve adult population health in Bamako.
文摘Objective:To investigate clinical signs in Trypanosoma brucei infection in albino rats.Methods:Fourteen rats grouped into 2 with 7 rats in each group were used to determine classical clinical manifestation of Trypanosoma brucei infection in rats.Group A rats were uninfected control and Group B rats were infected with Trypanosoma brucei.Results:Parasitaemia was recorded in Group B by(3.86±0.34)d and the peak of parasitaemia was observed at Day 5 post infection.Classical signs observed included squint eyes,raised whiskers,lethargy,no weight loss,pyrexia,isolation from the other rats,and starry hair coat.Conclusions:These signs could be diagnostic or aid in diagnosis of Trypanosoma brucei infection in rats.
文摘Purpose: The aim is to show epidemiological, clinical and etiological characteristics of palpebral wounds. Methodology: This was a retrospective study focusing on patients with an eyelid wound, over a 10-year period from 2012 to 2021. We collected and analyzed the data using Excel. Results: The frequency of eyelid wounds was 0.1%. The average age of our patients was 19.38 years with a range of 1 and 62 years. The sex ratio was 3.7. Eighty-one percent of patients lived in Dakar. Fifty-seven percent (57%) of patients consulted less than 24 hours after the trauma and 7% of patients on D1. The circumstances were brawls (11%), domestic accidents (9%), road accidents (6%), and work accidents (6%). We noted 1 case of dog bite. Thirteen patients presented with post-traumatic decreased visual acuity. Involvement of the isolated upper eyelid was noted in 40% of cases and both eyelids in 15% of cases. Involvement of the lacrimal ducts was noted in 17% of cases, and that of the free edge in 21% of cases. Eyelid wounds were associated with eyeball damage in 21% of cases. Various associated lesions were observed. Ninety-one percent of patients received surgical treatment. Three cases of superinfections, 1 case of conjunctival granuloma and 1 case of phthysis of the eyeball with postoperative retinal detachment were noted. Conclusion: Eyelid sores are relatively common in our context. They require rapid surgical treatment in order to preserve the functional and aesthetic prognosis. .
文摘BACKGROUND: Recent advances in molecular and genomic technologies and pancreatic imaging techniques provided some insights into genetic, environmental, immunologic, and pathobiological factors for chronic pancreatitis (CP). This study was undertaken to investigate the clinical manifestations of patients with chronic pancreatitis at our hospital. METHODS: The data of the patients with CP who had been treated at our hospital between 1997 and 2004 were analyzed. RESULTS: The major symptoms of the patients with CP were abdominal pain, dyspepsia, loss of weight, diabetes mellitus, pancreatic pseudocyst, steatorrhea, and calcification. Biliary diseases were found to be the first cause of CP in this study; but alcohol abuse was the major cause of CP in men and biliary diseases were the first etiological factors for CP in women. The etiological difference of constituent ratio between men and women was related to alcohol comsumption (P<0.01). CONCLUSIONS: During the past 8 years, biliary diseases have been the major etiological factors for CP, but their constituent ratio is decreasing, and the constituent ratio of alcohol abuse is increasing gradually. Alcohol tends to replace biliary diseases as the primary etiological factor for CP.

文摘Pituitary stalk interruption syndrome(PSIS)is a rare congenital abnormality characterized by thinning or disappearance of the pituitary stalk,hypoplasia of the anterior pituitary and an ectopic posterior pituitary.Although the etiology of PSIS is still unclear,gene changes and perinatal adverse events such as breech delivery may play important roles in the pathogenesis of PSIS.PSIS can cause multiple hormone deficiencies,such as growth hormone,which then cause a series of changes in the human body.On the one hand,hormone changes affect growth and development,and on the other hand,they could affect human metabolism and subsequently the liver resulting in nonalcoholic fatty liver disease(NAFLD).Under the synergistic effect of multiple mechanisms,the progression of NAFLD caused by PSIS is faster than that due to other causes.Therefore,in addition to early identification of PSIS,timely hormone replacement therapy and monitoring of relevant hormone levels,clinicians should routinely assess the liver function while managing PSIS.
文摘Primary biliary cirrhosis(PBC) is a chronic progressive cholestatic granulomatous, and destructive inflammatory lesion of small intralobular and septal bile ducts, which is likely to be caused by an autoimmune mechanism with a the presence of serum antimitochondrial antibodies and a potential tendency to progress to cirrhosis. Despite the fact that the etiology of this disease has beenunknown so far, there has been a considerable body of scientific evidence that can reveal the clinical and laboratory signs of PBC and the individual components of its pathogenesis and elaborate diagnostic criteria for the disease and its symptomatic therapy. Deficiencies in autoimmune tolerance are critical factors for the initiation and perpetuation of the disease. The purpose of this review is to summarize the data available in the literature and the author's findings on clinical and laboratory criteria for the diagnosis of PBC. This review describes the major clinical manifestations of the disease and the mechanisms of its development. It presents the immunological, biochemical, and morphological signs of PBC and their significance for its diagnosis. A great deal of novel scientific evidence for the problem of PBC has been accumulated. However, the inadequate efficiency of therapy for the disease lends impetus to the quest for its etiological factors and to further investigations of its pathogenetic mechanisms and, on this basis, to searches for new methods for its early diagnosis.

文摘Objective:To evaluate clinical and hematological aspects of dogs naturally infected with Hepatozoon canis(H.canis)presented at the Small Animal Clinics of Guru Angad Dev Veterinary and Animal Sciences University,Ludhiana.Methods:Blood films of 34 naturally infected dogs were examined for haematological alterations and parasitaemia.Signalment and clinical signs were recorded from the animals.Clinical histories were filled oul during the consultation.Results:Of the 34 positive dogs by Giemsa stained peripheral blood films.88.23%presented parasilaemia by H.canis only,while 11.77%had the combination of H.canis,Babesia sp.and Ehrlichia sp.Young male dogs less than oue-year-old,of nondescript breed,were the most commonly affected.And 26.47%were presented with anorexia/inappetence as the only clinical symptom.Other clinical symptoms were mild to moderate fever,pale mucosae and lethargy;a few were also showing the signs of vomiting and diarrhoea.Haematological alterations showed mainly normochromic-normocytic anaemia,leukocytosis and neutrophilia.Conclusions:The findings of this study substantiate that H.canis caused clinical and haematological alterations of the varied intensity in dogs,even with low parasilaemia.should he taken into consideration.
文摘Although there is not one specific sign or symptom related to alcoholic hepatitis(AH),a constellation of symptoms and signs can help make the diagnosis of AH with reasonable accuracy.Documentation of chronic and active alcohol abuse is paramount in making a diagnosis of AH.Clinical presentation after abstinence for more than 3 m should raise doubts about the diagnosis of AH and dictate the need for considering other causes of liver disease,decompensation of alcoholic cirrhosis,sepsis and malignancy as the cause of patient's clinical profile.
文摘Sheep pox is an infectious viral disease that affects specifically sheep and it is caused by the Capripoxvirus genus.The clinical signs include fever,diarrhea,difficulty breathing,nodules,lung lesions and death.In Morocco,the 2010 epidemic of sheep pox was characterized by the emergence of a nodular form of the disease.The local strain was isolated and the analysis of affected animals was positively confirmed by virus isolation and real-time polymerase chain reaction(RT-PCR).The epidemiological analysis of 911 data records showed that the virus is endemic in the country;an average of 350 cases per year with an epizootic evolution was observed in 2010.The incidence varies depending on provinces and the disease appears confined to the central and the eastern regions of the country where a very intensive sheep breeding activity is taking place.The statistical analysis showed that there is a positive correlation between the endemicity and the significant factor of the rural market(p=0.006).The annual average morbidity and mortality rates were 2.96%(1.26%to 4.32%)and 0.71%(0.41%to 0.94%),respectively.The clinical findings associated to the epidemiological data analysis confirmed the presence of sheep pox in its nodular form and suggest that new pathogenic strains may have been introduced from Mauritania.The purpose of this work was to provide a better description of the spatiotemporal evolution of sheep pox disease based on some epidemiological indicators and to put forward plausible hypotheses regarding the emergence of the virus in order to implement an adequate control strategy.

文摘Rationale, aim and objectives: The European (EU) regulation on medicinal products for pediatric use (EC 1901/2006), which became effective in 2007, aimed to stimulate the clinical testing of medications in minors in order to reduce off-label use. In consequence, the number of minors taking part in randomized controlled clinical trials (RCTs) is likely to increase. Clinical trials in minors require a complex methodological design, a careful consideration of risks and benefits and a high level of ethical reflection. Unfortunately, as to the quality of clinical trials and their publications in minors little is known. Therefore, we assessed published reports of randomized, controlled clinical trials in minors, focusing on a common disease (asthma) and a defined spectrum of lifethreatening diseases (malignant diseases). Method: In an exploratory design, we scanned the publications for methodological aspects as well as indicators of ethical soundness, e.g., statements that informed consent had been obtained before the start of the trial or that a Data and Safety Monitoring Board ensured the patients’ safety during the trial. We also looked for passages reflecting the debate on equipoise or other forms of weighing risks and benefits. Results: We found that many of these aspects, which according to the scientific literature and generally acknowledged guidelines are essential to ensure good-quality trials and trial reports, were not considered in the publications analyzed. Conclusion: Therefore, we call for a more transparent and consistent presentation of the trials, especially of safety aspects, relying on a more critical and transparent ethical reflection.
文摘Background: Non-traumatic coma is the most common pediatric medical emergency. Its clinical diagnosis is easy. The difficulty lies in finding the etiology. Objective: To determine the prevalence and clinical profiles of non-traumatic Coma at the Centre Hospitalier Universitaire Pédiatrique de Bangui (CHUPB). Methodology: This was a descriptive and analytical cross-sectional study conducted between January 1 and June 31, 2021, at CHUPB. Children aged 1 month to 15 years, admitted to the emergency room with a Glasgow score less than or equal to 8 without any traumatism were included. The variables studied were sociodemographic, clinical and paraclinical. Data were entered and analyzed using SPSS 20.0 statistical software. The statistical test used was Pearson’s chi<sup>2</sup>, any p-value Results: Of 8551 children hospitalized during the study period, 370 were hospitalized for non-traumatic coma: 4.32%. They were divided into 57.5% (n = 213) boys and 42.44% (n = 157) girls, giving a sex ratio of 1.35. Their mean age was 35.95 ± 27.21 months. Children aged 1 to 24 months represented 54.59% (n = 202) of cases. The mean time to the consultation was 2.91 days ± 1.8. Fever 86.48% (n = 320) and convulsions 80% (n = 296) were the main reasons for consultation. Coma stages II - III and IV represented 52.44% (n = 194), 42.97% (n = 159) and 4.59% (n = 17) respectively. Neuromalaria (29.72%;n = 110), meningitis-meningoencephalitis-encephalitis (30%;n = 111), sepsis (19.72%;n = 73) and acidosis Coma (5.40%;n = 20) were the main etiologies. Conclusion: Non-traumatic coma is common at CHUPB. Infections were the main etiology, particularly cerebral malaria. The reduction of its frequency requires, among others, the strengthening of the national monitoring malaria program. The strengthening of the technical platform for a good etiological diagnosis constitutes the other axis of prevention.
