It is a frequent and severe disease in Cameroon, thus constituting a significant public health problem. We aimed to describe VTE management in the Yaoundé Emergency Center, in particular the use of thrombolysis. Methods: This was a retrospective study on patients hospitalized at the Yaoundé Emergency Center for DVT and/or PE from January 1, 2015, to December 31, 2020. We collected clinical signs, paraclinical signs, risk factors of VTE, and management methods from each patient. Results: We recruited 106 participants. Dyspnea was the most frequent symptom;PE was the most common form of VTE in eight patients on 10. Obesity and high blood pressure were the main cardiovascular risk factors. The main clinical signs were oedema and pain in the limb for DVT, dyspnea, and tachycardia for PE. Heparinotherapy was the most commonly used management modality. Thrombolysis was performed in 7.5% of participants, especially in the case of hypotension or massive PE. Conclusion: In VTE management, thrombolysis remains the least used therapeutic modality in our context. Heparinotherapy remains the basis of the therapy.展开更多

Patients were included if they met the following criteria:(1) Medical indication for a liver biopsy in the setting of ALD;(2) recent(< 15 d) clinical, radiological, endoscopic and biological data available; and(3) estimated follow-up of at least 6 mo. Liver tissue from cirrhotic subjects obtained from transjugular liver biopsies was stained with Picro Sirius red and computer-assisted digital image analysis to determine fibrosis density using CPA was performed. RESULTS We included 61 patients with alcoholic ALD, subdivided in 41 active alcohol drinkers and 20 durably abstinent patients. Nine healthy liver donors served as controls. Mean CPA in patients with ALD was 7.1%, with no difference between active drinkers and abstinent patients(P = 0.17). Using a fibrosis density cutoff of 5%, we observed a positive correlation between high fibrosis density and the hepatic venous pressure gradient(HVPG) only in active drinkers(P = 0.02). At 12-mo of follow-up, in the group of active alcohol drinkers, patients reaching a composite outcome showed a higher HVPG value as compared to those who did not(18.5 mm Hg vs 14.5 mm Hg P < 0.04) whereas CPA values were similar(6.9% vs 11%, P = 0.23).CONCLUSION In active alcoholic ALD, CPA correlates to portal pressure but only HVPG predicts clinical events, pointing to the role of alcohol as a modulator of portal hypertension.展开更多

Although several acquired and genetic risk factors are known, about half that develop a thromboembolic event have no identifiable risk factor. Control of the inflammatory process is thought to be the key factor in risk reduction for thrombotic events. Prophylactic use of anticoagulants is not universally recommended, but possible use should be reviewed in an individual patient after evaluation of the risks, such as hemorrhage, compared to potential benefits. Particular consideration should be given if there has been a prior thrombotic event, if hospitalization will require surgery, or if an underlying coagulation disorder is present.展开更多

However, anecdotal reports mention that some patients with inflammatory bowel disease (IBD), who developed HPVG after diagnostic examinations of the colon, were successfully managed with antibiotic therapy and have followed benign courses. In contrast, among IBD patients, the development of HPVG is rarely caused by enterovenous fistula. We describe a 32-year-old man with Crohn's ileocolitis who presented with hypotension and fever associated with HPVG, as well as superior mesenteric vein thrombosis, possibly caused by enterovenous fistula, who was successfully managed by surgery. We also review the literature concerning portal venous gas associated with Crohn's disease.展开更多

It is?one of the most complications in admitted patients, particularly inlow-income settings. The epidemiological data on VTE are still lacking. Methods: We carried out a cross-sectional study in three hospitals in Yaoundé. We retrospectively reviewed records of patients admitted for VTE from January 2013 to December 2017. We collected data on socio-demography, clinical presentation, venous Doppler/pulmonary CT scan, and outcome. Results: We included 93 patients (43 males) with VTE. Their mean age was 53.3 ± 16.6 years. There were 46 (49.5%) cases of Deep Vein Thrombosis (DVT), 36 (38.7%) cases of Pulmonary Embolism (PE), and 11 (11.8%) cases of PE associated with DVT. The main risk factors were obesity/overweight (58.1%), immobility (43%), HIV infection (22.6%), prior admission (22.6%), and long trip (19.4%). The most frequent clinical presentation for PE was dyspnea (100%), tachypnea (87.2%), and chest pain (70.2%). For DVT, limb pain (93%), calf stiffness (86%), limb volume > 3 cm (82.4%) were the most common presentation. There were 9 (9.7%) in-hospital deaths. Mean hospital stay was 20.7 ± 30.8 days. Conclusion:VTE is underdiagnosed in our setting. Obesity and immobility were the main risk factors. Dyspnea and tachypnea were the main clinical presentation for PE whereas limb pain and calf stiffness were the main symptoms for DVT. In-hospital mortality is still high.展开更多

The objective of our study was to determine the hospital prevalence of VTE in this Nianakoro Fomba Regional Hospital (HNF) in Ségou, Mali, to describe the sociodemographic aspects of these patients and the therapeutic possibilities in this locality. Materials and Methods: We conducted a prospective descriptive study from June 2019 to June 2020 in the cardiology department of the HNF of Ségou. All patients of all ages and both sexes who had VTE on clinical and paraclinical criteria (pulmonary Angio scan and/or venous Doppler echo) during the study period were included. Result: 31 patients were included out of 366 hospitalized patients, with a hospital prevalence of 8.47%. The 41-60 and 61 - 80 age groups were both dominant with 35.48% of cases each. The female sex was the most represented with 58.06% of cases and a sex ratio of 0.97. High blood pressure (hypertension) was the preeminent cardiovascular risk factor in 32.2% of cases and predisposing factors for VTE were dominated by immobilization (41.94%), peripartum (16.13%) and heart failure (16.13%). Dyspnea and chest pain were the frequent reasons for consultation with 93.54% and 83.87% of cases respectively and 6 patients (19.35%) had calf pain. More than 3/4 of the patients had tachypnea or 90.32% and tachycardia in nearly 74.19%. The clinical probability of VTE was intermediate at 51.61% according to the Wells score. D-Dimers were elevated in 38.70%, or all 12 patients who performed it. The electrocardiogram (ECG) recorded a sinus rhythm in 93.54% of cases, a right branch block and atrial fibrillation (AF) in 35.48% and 6.45% of cases, respectively. Dilation of the right ventricle was present in 64.51% of cases with PAH in 61.29% on cardiac Doppler ultrasound. In the majority of cases (82.15%) it was a massive bilateral proximal and distal pulmonary embolism. Treatment was based on low molecular weight heparin (HPBM) and antivitamin K (AVK) in all patients (100%). No bleeding incidents;the average hospital stay was 10 days and an intra-hospital mortality rate of 29%.展开更多

Objective: We aimed to describe the epidemiologic, clinical, and therapeutic pattern of VTE in cancer patients followed-up in two reference hospitals in Cameroon over the past ten years. Methods: This was a cross-sectional retrospective study conducted in the oncology department of the General hospitals of Yaoundé and Douala. We included the medical records of all patients aged 18 years and above who had active cancer with a confirmed diagnosis of VTE from 2010 to 2021. Results: We analysed 408 patients’ medical records. The prevalence of VTE was 7.6%. All those having VTE had solid tumours. There were twenty (64.5%) cases of deep venous thrombosis, five (16.1%) cases of pulmonary embolism, and three (9.7%) cases of both. Poor performance status and chemotherapy were independently associated with the development of VTE. Most of the patients were treated with compression stockings and low molecular weight heparin. Conclusion: VTE prevalence is high among cancer patients in Cameroon. It is most frequent in solid tumours originating from the genitourinary system, the lung, the pancreas, and the brain.展开更多

Hemorrhoids can develop both inside and outside the rectum, and oftentimes, the cause of hemorrhoids remains unknown. This is an extremely common ailment faced by three out of four adults in their lifetime. Hemorrhoids can cause various kinds of complications, but the most common and serious ones are perianal thrombosis and incarcerated prolapsed internal hemorrhoids with subsequent thrombosis. They are accompanied by severe pain in the perianal region, and possible bleeding. Data on the coexistence of hemorrhoids with other conditions are sparse. Some data are consistent with a common pathophysiological link between straining at stool, constipation, and obstetrical events such as pregnancy and delivery. These events are also involved in the development of Chronic Vein Disease (CVD) or Chronic Vein Insufficiency (CVI). CVI is a condition that occurs when the venous walls or valves in the leg veins stop working properly, causing difficulty in blood returning to the heart from the legs. The present study was conducted with an aim to determine the frequency of complaints in hemorrhoidal patients and to assess the possible concomitance between hemorrhoidal disease and chronic venous disease.</span></span></span></span><span><span><span><span style="font-family:;" "=""> </span></span></span></span><span><span><span><span style="font-family:;" "=""><span><b></b></span><b><b><span style="font-family:Verdana;">Methods:</span></b><span></span></b><span style="font-family:Verdana;"> This was a multicenter, cross-sectional, observational study that enrolled patients spontaneously consulting for hemorrhoids in 17 different hospitals of different regions of Bangladesh from</span></span></span></span></span><span><span><span><span style="font-family:;" "=""> 1</span><sup><span style="font-family:Verdana;">st</span></sup><span style="font-family:Verdana;"> June 2018 to 31</span><sup><span style="font-family:Verdana;">st</span></sup><span style="font-family:Verdana;"> July 2018</span></span></span></span><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;">.</span></span></span></span><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;"> Patients’ demographic and lifestyle characteristics were recorded, information on hemorrhoidal grade and signs of chronic venous disease was collected.

The objective of our work is to correlate confirmed VTED with clinical probability scores using elements of interview and clinical examination. <strong>Methods:</strong> This was a retrospective study from January 1, 2012 to October 27, 2013. Venous thromboembolic disease was diagnosed by lower limb venous Doppler ultrasound for deep vein thrombosis and thoracic CT angiography for pulmonary embolism. <strong>Results:</strong> Our series included 74 cases of venous thromboembolic disease including 42 cases of deep vein thrombosis and 29 cases of pulmonary embolism. The average age was 48.5 ± 15.9 years. The sex ratio was 0.72. The patients came from the outpatient clinic in 67.57% of cases. The Wells score for pulmonary embolism showed excellent performance in the “Surgery/Cancer” subgroup where the low probability was zero. The revised Geneva score for pulmonary embolism, showing the same proportions of low (14.2%) and intermediate (85.7%) probability, did not discriminate the subgroup of patients with underlying heart disease from the one from a surgical or carcinological environment. <strong>Conclusion:</strong> Clinical probability scores are more suitable in surgical and oncological settings than in medical settings.展开更多

The reported cases are mostly hemangiomas fed either by the hepatic artery itself or by one of its branches. We present two unique hepatic AVM cases in the presence of congenital heart defects in which the AVM was not fed by the hepatic arterial system. Transcatheter coil embolisation was successfully carried out in both of them by using non-detachable Gianturco coils. Complete occlusion was achieved without any sequel.展开更多

文摘The utilisation of polygenic scoring models may enhance the clinician’s ability to risk stratify an inflammatory bowel disease patient’s individual risk for venous thromboembolism(VTE)and guide the appropriate usage of VTE thromboprophylaxis,yet there is a need to validate such models in ethnically diverse populations.

文摘Inflammatory bowel disease(IBD),including Crohn’s disease(CD)and ulcerative colitis(UC),is a chronic inflammatory disease of the digestive tract with increasing prevalence globally.Although venous thromboembolism(VTE)is a major complication in IBD patients,it is often underappreciated with limited tools for risk stratification.AIM To estimate the proportion of VTE among IBD patients and assess genetic risk factors(monogenic and polygenic)for VTE.METHODS Incident VTE was followed for 8465 IBD patients in the UK Biobank(UKB).The associations of VTE with F5 factor V leiden(FVL)mutation,F2 G20210A prothrombin gene mutation(PGM),and polygenic score(PGS003332)were tested using Cox hazards regression analysis,adjusting for age at IBD diagnosis,gender,and genetic background(top 10 principal components).The performance of genetic risk factors for discriminating VTE diagnosis was estimated using the area under the receiver operating characteristic curve(AUC).RESULTS The overall proportion of incident VTE was 4.70%in IBD patients and was similar for CD(4.46%),UC(4.49%),and unclassified(6.42%),and comparable to that of cancer patients(4.66%)who are well-known at increased risk for VTE.Mutation carriers of F5/F2 had a significantly increased risk for VTE compared to non-mutation carriers,hazard ratio(HR)was 1.94,95%confidence interval(CI):1.42-2.65.In contrast,patients with the top PGS decile had a considerably higher risk for VTE compared to those with intermediate scores(middle 8 deciles),HR was 2.06(95%CI:1.57-2.71).The AUC for differentiating VTE diagnosis was 0.64(95%CI:0.61-0.67),0.68(95%CI:0.66-0.71),and 0.69(95%CI:0.66-0.71),respectively,for F5/F2 mutation carriers,PGS,and combined.CONCLUSION Similar to cancer patients,VTE complications are common in IBD patients.PGS provides more informative risk information than F5/F2 mutations(FVL and PGM)for personalized thromboprophylaxis.
文摘Background: Venous thromboembolic disease (VTE) is a clinical entity whose two clinical manifestations are deep vein thrombosis (DVT) and pulmonary embolism (PE). It is a frequent and severe disease in Cameroon, thus constituting a significant public health problem. We aimed to describe VTE management in the Yaoundé Emergency Center, in particular the use of thrombolysis. Methods: This was a retrospective study on patients hospitalized at the Yaoundé Emergency Center for DVT and/or PE from January 1, 2015, to December 31, 2020. We collected clinical signs, paraclinical signs, risk factors of VTE, and management methods from each patient. Results: We recruited 106 participants. Dyspnea was the most frequent symptom;PE was the most common form of VTE in eight patients on 10. Obesity and high blood pressure were the main cardiovascular risk factors. The main clinical signs were oedema and pain in the limb for DVT, dyspnea, and tachycardia for PE. Heparinotherapy was the most commonly used management modality. Thrombolysis was performed in 7.5% of participants, especially in the case of hypotension or massive PE. Conclusion: In VTE management, thrombolysis remains the least used therapeutic modality in our context. Heparinotherapy remains the basis of the therapy.
文摘BACKGROUND The May-Hegglin anomaly is among a group of genetic disorders known as MYH9-related disease.Patients with inherited platelet disorders such as May-Hegglin anomaly are at a variably increased risk for bleeding due to a combination of platelet dysfunction and thrombocytopenia.Patients admitted to the hospital with coronavirus disease 2019(COVID-19)infection are at an increased risk for a venous thromboembolism event(VTE).The National Institutes of Health COVID-19 treatment guidelines recommend using a prophylactic dose of heparin as VTE prophylaxis for adults who are receiving high-flow oxygen.We describe a patient admitted for COVID-19 infection with pneumonia and a history of May-Hegglin anomaly.The patient presented a challenge to determine prophylactic anticoagulation as there are no clear guidelines for this patient population.CASE SUMMARY Herein,we describe the case of a 39-year-old woman admitted with acute hypoxic respiratory failure secondary to COVID-19 pneumonia.She had a history of May-Hegglin anomaly and demonstrated risk for bleeding since childhood,including a life-threatening bleeding event at the age of 9 years requiring blood and platelet transfusions.Her baseline platelet count was 40-50×109/L throughout her adult life.Her family history was also notable for May-Hegglin disorder in her mother,maternal uncle,maternal grandfather and her son.Computed tomography/pulmonary angiography revealed bilateral consolidative opacities consistent with multifocal pneumonia.Complete blood count was notable for platelet count of 54×109/L.She was admitted for inpatient respiratory support with high-flow oxygen per nasal cannula and was managed with guideline-directed therapy for COVID-19,including baricitinib and dexamethasone.The Hematology/Oncology consultation team was requested to assist with management of VTE prophylaxis in the setting of active COVID-19 infection and an inherited bleeding disorder.After review of the literature and careful consideration of risks and benefits,it was decided to treat the patient with prophylactic enoxaparin.She was closely monitored in the hospital for bleeding and worsening thrombocytopenia.She had no bleeding or signs of VTE.Her respiratory status improved,and she was discharged home after 5 d of hospitalization with supplemental oxygen by nasal cannula and dexamethasone.At the 6-month follow-up,the patient successfully discontinued her home oxygen use after only a few weeks following discharge.CONCLUSION The patient presented a challenge to determine prophylactic anticoagulation as anticoagulation guidelines exist for patients with COVID-19,but there are no clear guidelines for management of patients with COVID-19 and inherited bleeding disorders,particularly those with MYH9-related disease.She was discharged after recovery from the COVID-19 infection without bleeding or thrombosis.As there are no published guidelines for this situation,we present a pragmatic,informed approach to a patient with MYH9-related disease who had an indication for anticoagulation.
文摘Portal hypertension(PH)has traditionally been observed as a consequence of significant fibrosis and cirrhosis in advanced non-alcoholic fatty liver disease(NAFLD).However,recent studies have provided evidence that PH may develop in earlier stages of NAFLD,suggesting that there are additional pathogenetic mechanisms at work in addition to liver fibrosis.The early development of PH in NAFLD is associated with hepatocellular lipid accumulation and ballooning,leading to the compression of liver sinusoids.External compression and intraluminal obstacles cause mechanical forces such as strain,shear stress and elevated hydrostatic pressure that in turn activate mechanotransduction pathways,resulting in endothelial dysfunction and the development of fibrosis.The spatial distribution of histological and functional changes in the periportal and perisinusoidal areas of the liver lobule are considered responsible for the pre-sinusoidal component of PH in patients with NAFLD.Thus,current diagnostic methods such as hepatic venous pressure gradient(HVPG)measurement tend to underestimate portal pressure(PP)in NAFLD patients,who might decompensate below the HVPG threshold of 10 mmHg,which is traditionally considered the most relevant indicator of clinically significant portal hypertension(CSPH).This creates further challenges in finding a reliable diagnostic method to stratify the prognostic risk in this population of patients.In theory,the measurement of the portal pressure gradient guided by endoscopic ultrasound might overcome the limitations of HVPG measurement by avoiding the influence of the pre-sinusoidal component,but more investigations are needed to test its clinical utility for this indication.Liver and spleen stiffness measurement in combination with platelet count is currently the best-validated non-invasive approach for diagnosing CSPH and varices needing treatment.Lifestyle change remains the cornerstone of the treatment of PH in NAFLD,together with correcting the components of metabolic syndrome,using nonselective beta blockers,whereas emerging candidate drugs require more robust confirmation from clinical trials.
文摘Patients with inflammatory bowel disease(IBD)are at an increased risk for venous thromboembolism(VTE).VTE events carry significant morbidity and mortality,and have been associated with worse outcomes in patients with IBD.Studies have suggested that the hypercoagulable nature of the disease stems from a complex interplay of systems that include the coagulation cascade,natural coagulation inhibitors,fibrinolytic system,endothelium,immune system,and platelets.Additionally,clinical factors that increase the likelihood of a VTE event among IBD patients include older age(though some studies suggest younger patients have a higher relative risk of VTE,the incidence in this population is much lower as compared to the older IBD patient population),pregnancy,active disease,more extensive disease,hospitalization,the use of certain medications such as corticosteroids or tofacitinb,and IBD-related surgeries.Despite the increased risk of VTE among IBD patients and the safety of pharmacologic prophylaxis,adherence rates among hospitalized IBD patients appear to be low.Furthermore,recent data suggests that there is a population of high risk IBD patients who may benefit from post-discharge prophylaxis.This review will provide an overview of patient specific factors that affect VTE risk,elucidate reasons for lack of VTE prophylaxis among hospitalized IBD patients,and focus on recent data describing those at highest risk for recurrent VTE post-hospital discharge.
文摘Inflammatory bowel disease(IBD)patients have an increased risk of venous thromboembolism(VTE),which represents a significant cause of morbidity and mortality.The most common sites of VTE in IBD patients are the deep veins of the legs and pulmonary system,followed by the portal and mesenteric veins.However,other sites may also be involved,such as the cerebrovascular and retinal veins.The aetiology of VTE is multifactorial,including both inherited and acquired risk factors that,when simultaneously present,multiply the risk to the patient.VTE prevention involves correcting modifiable risk factors,such as disease activity,vitamin deficiency,dehydration and prolonged immobilisation.The role of mechanical and pharmacological prophylaxis against VTE using anticoagulants is also crucial.However,although guidelines recommend thromboprophylaxis for IBD patients,this method is still poorly implemented because of concerns about its safety and a lack of awareness of the magnitude of thrombotic risk in these patients.Further efforts are required to increase the rate of pharmacological prevention of VTE in IBD patients to avoid preventable morbidity and mortality.
文摘Patients with inflammatory bowel disease(IBD)may have an increased risk of venous thrombosis(VTE).PubMed,ISI Web of Knowledge and Scopus were searched to identify studies investigating the risk of VTE and the prevalence of acquired and genetic VTE risk factors and prothrombotic abnormalities in IBD.Overall,IBD patients have a two-to fourfold increased risk of VTE compared with healthy controls,with an overall incidence rate of 1%-8%.The majority of studies did not show significant differences in the risk of VTE between Crohn’s disease and ulcerative colitis.Several acquired factors are responsible for the increased risk of VTEin IBD:inflammatory activity,hospitalisation,surgery,pregnancy,disease phenotype(e.g.,fistulising disease,colonic involvement and extensive involvement)and drug therapy(mainly steroids).There is also convincing evidence from basic science and from clinical and epidemiological studies that IBD is associated with several prothrombotic abnormalities,including initiation of the coagulation system,downregulation of natural anticoagulant mechanisms,impairment of fibrinolysis,increased platelet count and reactivity and dysfunction of the endothelium.Classical genetic alterations are not generally found more often in IBD patients than in nonIBD patients,suggesting that genetics does not explain the greater risk of VTE in these patients.IBD VTE may have clinical specificities,namely an earlier first episode of VTE in life,high recurrence rate,decreased efficacy of some drugs in preventing further episodes and poor prognosis.Clinicians should be aware of these risks,and adequate prophylactic actions should be taken in patients who have disease activity,are hospitalised,are submitted to surgery or are undergoing treatment.

文摘AIM:To determine the optimal initial treatment modality for acute superior mesenteric vein thrombosis(ASMVT)in patients with circumscribed peritonitis.METHODS:A retrospective review was made of the Vascular Surgery Department’s medical records to identify adult patients(≥18 years old)presenting with circumscribed peritonitis and diagnosed with ASMVT by imaging or endoscopic examination.Patients were selected from the time period between October 2009and October 2012 to assess the overall performance of a new first-line treatment policy implemented in May2011 for patients with circumscribed peritonitis,which recommends transcatheter thrombolysis with local anticoagulation and endovascular mechanical thrombectomy.Of the 25 patients selected for study inclusion,12 had undergone emergency surgical exploration(group 1)and 13 had undergone the initial catheterdirected thrombolysis(group 2).Data extracted from each patient’s records for statistical analyses included method of diagnosis,symptoms,etiology and risk factors,thrombus location,initial management,morbidity,mortality,duration and total cost of hospitalization(in Renminbi,RMB),secondary operation,total length of bowel resection,duration of and findings in follow-up,and death/survival.RESULTS:The two treatment groups showed similar rates of morbidity,30-d mortality,and 1-year survival,as well as similar demographic characteristics,etiology or risk factors,computed tomography characteristics,symptoms,findings of blood testing at admission,complications,secondary operations,and follow-up outcomes.In contrast,the patients who received the initial non-operative treatment of transcatheter thrombolysis had significantly shorter durations of admission to symptom elimination(group 1:18.25±7.69 d vs group 2:7.23±2.42 d)and hospital stay(43.00±13.77 d vs 20.46±6.59 d),and early enteral or oral nutrition restoration(20.50±5.13 d vs 8.92±1.89 d),as well as significantly less total length of bowel resection(170.83±61.27 cm vs 29.23±50.24 cm)and lower total cost(200020.4±91505.62 RMB vs 72785.6±21828.16 RMB)(P<0.05 for all).Statistical analyses suggested that initial transcatheter thrombolysis is correlated with quicker resolution of the thrombus,earlier improvement of symptoms,stimulation of collateral vessel development,reversal of intestinal ischemia,receipt of localizing bowel resection to prevent short bowel syndrome,shorter hospitalization,and lower overall cost of treatment.CONCLUSION:For ASMVT patients with circumscribed peritonitis,early diagnosis is key to survival,and nonoperative transcatheter thrombolysis is feasible and effective as an initial treatment.
文摘AIM To explore the relationship between collagen proportionate area(CPA) and portal hypertension-related clinical manifestations in alcoholic liver disease(ALD).METHODS Retrospective study with chart review of patients with ALD adressed to our center between January 2012 and December 2013 for a transjugular liver biopsy(TJLB) and hepatic hemodynamic study. Patients were included if they met the following criteria:(1) Medical indication for a liver biopsy in the setting of ALD;(2) recent(< 15 d) clinical, radiological, endoscopic and biological data available; and(3) estimated follow-up of at least 6 mo. Liver tissue from cirrhotic subjects obtained from transjugular liver biopsies was stained with Picro Sirius red and computer-assisted digital image analysis to determine fibrosis density using CPA was performed. RESULTS We included 61 patients with alcoholic ALD, subdivided in 41 active alcohol drinkers and 20 durably abstinent patients. Nine healthy liver donors served as controls. Mean CPA in patients with ALD was 7.1%, with no difference between active drinkers and abstinent patients(P = 0.17). Using a fibrosis density cutoff of 5%, we observed a positive correlation between high fibrosis density and the hepatic venous pressure gradient(HVPG) only in active drinkers(P = 0.02). At 12-mo of follow-up, in the group of active alcohol drinkers, patients reaching a composite outcome showed a higher HVPG value as compared to those who did not(18.5 mm Hg vs 14.5 mm Hg P < 0.04) whereas CPA values were similar(6.9% vs 11%, P = 0.23).CONCLUSION In active alcoholic ALD, CPA correlates to portal pressure but only HVPG predicts clinical events, pointing to the role of alcohol as a modulator of portal hypertension.
文摘Venous thrombosis and thromboembolism appear to be increased in patients with inflammatory bowel disease. Although several acquired and genetic risk factors are known, about half that develop a thromboembolic event have no identifiable risk factor. Control of the inflammatory process is thought to be the key factor in risk reduction for thrombotic events. Prophylactic use of anticoagulants is not universally recommended, but possible use should be reviewed in an individual patient after evaluation of the risks, such as hemorrhage, compared to potential benefits. Particular consideration should be given if there has been a prior thrombotic event, if hospitalization will require surgery, or if an underlying coagulation disorder is present.
文摘The presence of hepatic portal venous gas (HPVG) is associated with numerous diseases, and has been regarded as a serious, even catastrophic condition. However, anecdotal reports mention that some patients with inflammatory bowel disease (IBD), who developed HPVG after diagnostic examinations of the colon, were successfully managed with antibiotic therapy and have followed benign courses. In contrast, among IBD patients, the development of HPVG is rarely caused by enterovenous fistula. We describe a 32-year-old man with Crohn's ileocolitis who presented with hypotension and fever associated with HPVG, as well as superior mesenteric vein thrombosis, possibly caused by enterovenous fistula, who was successfully managed by surgery. We also review the literature concerning portal venous gas associated with Crohn's disease.
文摘Background: Venous thromboembolic disease (VTE) is one of the main causes of cardiovascular death and a public health problem worldwide. It is?one of the most complications in admitted patients, particularly inlow-income settings. The epidemiological data on VTE are still lacking. Methods: We carried out a cross-sectional study in three hospitals in Yaoundé. We retrospectively reviewed records of patients admitted for VTE from January 2013 to December 2017. We collected data on socio-demography, clinical presentation, venous Doppler/pulmonary CT scan, and outcome. Results: We included 93 patients (43 males) with VTE. Their mean age was 53.3 ± 16.6 years. There were 46 (49.5%) cases of Deep Vein Thrombosis (DVT), 36 (38.7%) cases of Pulmonary Embolism (PE), and 11 (11.8%) cases of PE associated with DVT. The main risk factors were obesity/overweight (58.1%), immobility (43%), HIV infection (22.6%), prior admission (22.6%), and long trip (19.4%). The most frequent clinical presentation for PE was dyspnea (100%), tachypnea (87.2%), and chest pain (70.2%). For DVT, limb pain (93%), calf stiffness (86%), limb volume > 3 cm (82.4%) were the most common presentation. There were 9 (9.7%) in-hospital deaths. Mean hospital stay was 20.7 ± 30.8 days. Conclusion:VTE is underdiagnosed in our setting. Obesity and immobility were the main risk factors. Dyspnea and tachypnea were the main clinical presentation for PE whereas limb pain and calf stiffness were the main symptoms for DVT. In-hospital mortality is still high.
文摘Venous thromboembolic disease (VTE) is a nosological group that consists mainly of deep vein thrombosis (DVT) and pulmonary embolism (PE). The objective of our study was to determine the hospital prevalence of VTE in this Nianakoro Fomba Regional Hospital (HNF) in Ségou, Mali, to describe the sociodemographic aspects of these patients and the therapeutic possibilities in this locality. Materials and Methods: We conducted a prospective descriptive study from June 2019 to June 2020 in the cardiology department of the HNF of Ségou. All patients of all ages and both sexes who had VTE on clinical and paraclinical criteria (pulmonary Angio scan and/or venous Doppler echo) during the study period were included. Result: 31 patients were included out of 366 hospitalized patients, with a hospital prevalence of 8.47%. The 41-60 and 61 - 80 age groups were both dominant with 35.48% of cases each. The female sex was the most represented with 58.06% of cases and a sex ratio of 0.97. High blood pressure (hypertension) was the preeminent cardiovascular risk factor in 32.2% of cases and predisposing factors for VTE were dominated by immobilization (41.94%), peripartum (16.13%) and heart failure (16.13%). Dyspnea and chest pain were the frequent reasons for consultation with 93.54% and 83.87% of cases respectively and 6 patients (19.35%) had calf pain. More than 3/4 of the patients had tachypnea or 90.32% and tachycardia in nearly 74.19%. The clinical probability of VTE was intermediate at 51.61% according to the Wells score. D-Dimers were elevated in 38.70%, or all 12 patients who performed it. The electrocardiogram (ECG) recorded a sinus rhythm in 93.54% of cases, a right branch block and atrial fibrillation (AF) in 35.48% and 6.45% of cases, respectively. Dilation of the right ventricle was present in 64.51% of cases with PAH in 61.29% on cardiac Doppler ultrasound. In the majority of cases (82.15%) it was a massive bilateral proximal and distal pulmonary embolism. Treatment was based on low molecular weight heparin (HPBM) and antivitamin K (AVK) in all patients (100%). No bleeding incidents;the average hospital stay was 10 days and an intra-hospital mortality rate of 29%.
文摘Background: Cancer increases the incidence of venous thromboembolic disease (VTE), which represents a significant cause of morbidity, mortality, and economic burden in cancer patients. Objective: We aimed to describe the epidemiologic, clinical, and therapeutic pattern of VTE in cancer patients followed-up in two reference hospitals in Cameroon over the past ten years. Methods: This was a cross-sectional retrospective study conducted in the oncology department of the General hospitals of Yaoundé and Douala. We included the medical records of all patients aged 18 years and above who had active cancer with a confirmed diagnosis of VTE from 2010 to 2021. Results: We analysed 408 patients’ medical records. The prevalence of VTE was 7.6%. All those having VTE had solid tumours. There were twenty (64.5%) cases of deep venous thrombosis, five (16.1%) cases of pulmonary embolism, and three (9.7%) cases of both. Poor performance status and chemotherapy were independently associated with the development of VTE. Most of the patients were treated with compression stockings and low molecular weight heparin. Conclusion: VTE prevalence is high among cancer patients in Cameroon. It is most frequent in solid tumours originating from the genitourinary system, the lung, the pancreas, and the brain.
文摘<p style="margin-left:10.0pt;"> <span><span><span style="font-family:;" "=""><b><b><span style="font-family:Verdana;">Introduction:</span></b><span></span></b><span style="font-family:Verdana;"> Hemorrhoids, more commonly known as piles, are swollen veins, similar to varicose veins in the lower rectum. Hemorrhoids can develop both inside and outside the rectum, and oftentimes, the cause of hemorrhoids remains unknown. This is an extremely common ailment faced by three out of four adults in their lifetime. Hemorrhoids can cause various kinds of complications, but the most common and serious ones are perianal thrombosis and incarcerated prolapsed internal hemorrhoids with subsequent thrombosis. They are accompanied by severe pain in the perianal region, and possible bleeding. Data on the coexistence of hemorrhoids with other conditions are sparse. Some data are consistent with a common pathophysiological link between straining at stool, constipation, and obstetrical events such as pregnancy and delivery. These events are also involved in the development of Chronic Vein Disease (CVD) or Chronic Vein Insufficiency (CVI). CVI is a condition that occurs when the venous walls or valves in the leg veins stop working properly, causing difficulty in blood returning to the heart from the legs. The present study was conducted with an aim to determine the frequency of complaints in hemorrhoidal patients and to assess the possible concomitance between hemorrhoidal disease and chronic venous disease.</span></span></span></span><span><span><span><span style="font-family:;" "=""> </span></span></span></span><span><span><span><span style="font-family:;" "=""><span><b></b></span><b><b><span style="font-family:Verdana;">Methods:</span></b><span></span></b><span style="font-family:Verdana;"> This was a multicenter, cross-sectional, observational study that enrolled patients spontaneously consulting for hemorrhoids in 17 different hospitals of different regions of Bangladesh from</span></span></span></span></span><span><span><span><span style="font-family:;" "=""> 1</span><sup><span style="font-family:Verdana;">st</span></sup><span style="font-family:Verdana;"> June 2018 to 31</span><sup><span style="font-family:Verdana;">st</span></sup><span style="font-family:Verdana;"> July 2018</span></span></span></span><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;">.</span></span></span></span><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;"> Patients’ demographic and lifestyle characteristics were recorded, information on hemorrhoidal grade and signs of chronic venous disease was collected.

文摘<strong>Introduction</strong>: Venous thromboembolic disease (VTED), associating deep vein thrombosis and pulmonary embolism, represents a major public health issue. The objective of our work is to correlate confirmed VTED with clinical probability scores using elements of interview and clinical examination. <strong>Methods:</strong> This was a retrospective study from January 1, 2012 to October 27, 2013. Venous thromboembolic disease was diagnosed by lower limb venous Doppler ultrasound for deep vein thrombosis and thoracic CT angiography for pulmonary embolism. <strong>Results:</strong> Our series included 74 cases of venous thromboembolic disease including 42 cases of deep vein thrombosis and 29 cases of pulmonary embolism. The average age was 48.5 ± 15.9 years. The sex ratio was 0.72. The patients came from the outpatient clinic in 67.57% of cases. The Wells score for pulmonary embolism showed excellent performance in the “Surgery/Cancer” subgroup where the low probability was zero. The revised Geneva score for pulmonary embolism, showing the same proportions of low (14.2%) and intermediate (85.7%) probability, did not discriminate the subgroup of patients with underlying heart disease from the one from a surgical or carcinological environment. <strong>Conclusion:</strong> Clinical probability scores are more suitable in surgical and oncological settings than in medical settings.
文摘Congenital hepatic arterio-venous malformations (AVM) are rare vascular anomalies and have rarely been reported in the presence of congeni-tal heart disease. The reported cases are mostly hemangiomas fed either by the hepatic artery itself or by one of its branches. We present two unique hepatic AVM cases in the presence of congenital heart defects in which the AVM was not fed by the hepatic arterial system. Transcatheter coil embolisation was successfully carried out in both of them by using non-detachable Gianturco coils. Complete occlusion was achieved without any sequel.
文摘BACKGROUND Chronic obstructive pulmonary disease(COPD)combined with spontaneous pneumothorax,is characterized by significant decline in lung function,and even cause cardiopulmonary failure and hypoxia.AIM To evaluate the clinical effectiveness of central venous catheters and indwelling pleural catheters(IPC)in managing closed thoracic drainage in patients diagnosed with COPD with concomitant by spontaneous pneumothorax.METHODS Retrospective analysis was conducted on the clinical information of 60 elderly patients with COPD complicated by spontaneous pneumothorax admitted to the Shexian Branch of the second affiliated hospital of Zhejiang university school of medicine between March 2020 and March 2023.The clinical efficacy,complications,hospitalization duration,and costs were compared between patients with an indwelling thoracic catheter and those with a central venous catheter.Univariate logistic regression was used to analyze the causes of catheter displacement.RESULTS According to our findings,there were significant differences in the IPC group’s clinical efficacy,catheter operation time,and lung recruitment time(P<0.05).Comparing the complications after catheter treatment between the two groups revealed statistically significant variations in the incidence of postoperative analgesics,catheter abscission,catheter blockage,and subcutaneous emphysema in the IPC group(P<0.05).Univariate analysis demonstrated significant differences between patients with and without catheter dislodgement regarding duty nurse’s working years(less than three),Acute Physiology and Chronic Health Evaluation II(APACHE II)scores(less than 15),lack of catheter suture fixation,and the proportion of catheters not fixed twice(P<0.05).CONCLUSION Our results demonstrated that when treating elderly COPD patients with spontaneous pneumothorax,indwelling thoracic catheters are more effective than the central venous catheter group.Patients’catheter shedding is influenced by the primary nurse’s working years,APACHE II scores,and catheter fixation technique.

文摘BACKGROUND Nonalcoholic fatty liver disease(NAFLD)is the most common cause of chronic liver disease worldwide.Studies have shown a strong association between nonalcoholic steatohepatitis(NASH)cirrhosis and portal vein thrombosis.Specifically,there is paucity of data on the association of NASH and venous thromboembolism(VTE),with one such study predicting a 2.5-fold increased risk for VTE compared to other liver diseases in hospitalized patients.The mechanism is believed to be a hepatocellular injury,which causes a chronic inflammatory state leading to the unregulated activation of procoagulant factors.There has been no prior analysis of the degree of steatosis and fibrosis(measured using transient elastography,commonly known as FibroScan)in NASH and its association with VTE.AIM To examine the association between the degree of hepatic steatosis and fibrosis,quantified by transient elastography,and the incidence of VTE in patients with NASH.METHODS In our case-control study,we included patients with a documented diagnosis of NASH.We excluded patients with inherited thrombophilia,hemoglobinopathy,malignancy,alcohol use disorder,autoimmune hepatitis,and primary biliary cirrhosis.The collected data included age,demographics,tobacco use,recreational drug use,medical history,and vibration controlled transient elastography scores.VTE-specific data included the location,type of anticoagulant,need for hospital stay,and history of VTE recurrence.Steatosis was categorized as S0-S1(mild)and S2-S3(moderate to severe)based on the controlled attenuation parameter score.Fibrosis was classified based on the kilopascal score and graded as F0-F1(Metavir stage),F2,F3,and F4(cirrhosis).χ^(2) and Mann-Whitney U tests were used for the qualitative and quantitative variable analyses,respectively.Furthermore,we performed a logistic regression using VTE as the dependent variable.RESULTS A total of 415 patients were analyzed,and 386 met the inclusion criteria.51 and 335 patients were included in the VTE and non-VTE groups,respectively.Patients with VTE had a mean age of 60.63 years compared to 55.22 years in the non-VTE group(P<0.014).Patients with VTE had a higher body mass index(31.14 kg/m²vs 29.30 kg/m²)and a higher prevalence of diabetes mellitus(29.4%vs 13.1%).The history of NASH was significantly higher in the VTE group(45.1%vs 30.4%,P<0.037).Furthermore,moderate-to-severe steatosis was significantly higher in the VTE group(66.7%vs 47.2%,P<0.009).Similarly,the F2-F4 fibrosis grade had a prevalence of 58.8%in the VTE group compared to 38.5%in the non-VTE group(P<0.006).On logistic regression,using VTE as a dependent variable,diabetes mellitus had an odds ratio(OR)=1.702(P<0.015),and F2-F4 fibrosis grade had an OR=1.5(P<0.033).CONCLUSION Our analysis shows that NASH is an independent risk factor for VTE,especially deep vein thrombosis.There was a statistically significant association between the incidence of VTE,moderate-to-severe steatosis,and fibrosis.All hospitalized patients should be considered for medical thromboprophylaxis,particularly those with NASH.
