Pulmonary embolism (PE) is the most serious clinical presentation of VTE. Epidemiological and clinical data on PE are still lacking in Africa, particularly in Cameroon. This study aimed at determining the clinical features as well as imaging presentation and outcome of pulmonary embolism. Methods: A cross-sectional study was carried out in three hospitals in Douala. We retrospectively reviewed patient records admitted for PE from January 2009 to May 2017. We collected data on epidemiology, clinical presentation, venous Doppler/pulmonary computed tomographic angiography (CTA), and outcome. Results: We included 103 patients (56 males) with PE. Their median age was 52 years. The main risk factors were obesity (49.5%), hypertension (35.0%), long trip (24.3%) and cancer (18.4%). The most frequent clinical presentations were dyspnoea (83.4%), chest pain (78.6%), and cough (40.8%). Additionally, pleural effusion (32.8%), atelectasis (25.7%) and pulmonary hyperlucency (20.0%) were the most frequent findings on chest X-ray. The main abnormalities found in electrocardiogram were sinus tachycardia (63.4%), S1Q3T3 aspect (37.6%) and right axial deviation (28.7%). Moreover, right cavities dilatation (26.0%), pulmonary artery hypertension (35.0%) and pulmonary artery dilatation (21.0%) were the main echocardiographic findings. Low-molecular-weight heparin (LMWH) was the initial anticoagulant in all cases. There were 19 (18.4%) in-hospital deaths, and the mean hospital stay was 8.5 ± 5 days. Conclusion: PE is not rare in our setting. Obesity, long trip and cancer are the main risk factors, while dyspnoea, chest pain and respiratory distress are the main clinical presentation for PE. LMWH remains the therapeutic agent of choice. Lastly, in-hospital mortality is very high.展开更多

Traditional Chinese Medicine (TCM) syndrome aims to reflect the characteristics of diseases and is the basic principle of TCM treatment of diseases. This study aimed to summarize the distribution pattern of TCM syndromes in patients with hyperlipidemia. Methods: The frequency, characteristics and distribution of all TCM syndromes of 1012 patients with hyperlipidemia were analyzed. Results: The main disease types determined by frequency of 1012 patients included hypertriglyceridemia combined with hypo high-density lipoprotein cholesterolemia (19.76%), hypo high-density lipoprotein cholesterolemia (18.58%), hypercholesterolemia (16.50%), mixed hyperlipidemia (16.40%), and hypertriglyceridemia (15.12%). The distribution of TCM syndromes, in order of frequency, was as follows: Qi-deficiency and blood stasis syndrome (23.52%), liver depression and spleen deficiency (9.88%), syndrome of qi stagnation and blood stasis (9.29%), phlegm stasis syndrome (7.41%), and syndrome of yang deficiency of spleen and kidney (6.92%). Conclusion: Qi-deficiency and blood stasis syndrome and liver depression and spleen deficiency are the most common TCM syndromes in patients with hyperlipidemia.展开更多

The cumulative incidence of complex perianal fistulas in CD from two referral-centre studies was 12%-14%(follow-up time, 12 years in one study; not reported in the second study). Complex perianal fistulas result in greatly diminished quality of life; up to 59% of patients are at risk of faecal incontinence. Treatments include combinations of medical and surgical interventions and expanded allogeneic adipose-derived stem cells. High proportions of patients experience lack of or inadequate response to treatment(failure and relapse rates,respectively: medical, 12%-73% and 0%-41%; surgical:0%-100% and 11%.20%; combined medical/surgical:0%-80% and 0%-50%; stem cells: 29%-47% and not reported). Few studies(1 of infliximab; 3 of surgical interventions)have been conducted in treatment-refractory patients, a population with high unmet needs. Limited data exist on the clinical value of anti-tumour necrosis factor-α dose escalation in patients with complex perianal fistulas in CD.CONCLUSION Complex perianal fistulas in CD pose substantial clinical and humanistic burden. There is a need for effective treatments, especially for patients refractory to antitumour necrosis factor-α agents, as evidenced by high failure and relapse rates.展开更多

It has a significant impact on both society and patients' quality of life. The epidemiology, clinical presentation, and management of IBS may vary in different geographical regions due to differences in diet, gastrointestinal infection, socio-cultural and psychosocial factors, religious and illness beliefs, symptom perception and reporting. Although previous reviews and consensus reports on IBS in Asia have been published, Asia is quite diverse socio-demographically. In this context, India, Bangladesh and Malaysia share some similarities, including:(1) large proportion of the population living in rural areas;(2) rapid development and associated lifestyle changes in urban areas; and(3) dietary, cultural and religious practices. The present review explores the clinical and epidemiological data on IBS from these three major nations in South and South-East Asia. In-depth review of the literature revealed important differences between IBS in the East, as revealed by studies from these three countries, and the West; these include a predominantly rural profile, differences in bowel habit and symptom profile, raising concern with regards to diagnostic criteria and subtyping of IBS, higher dietary fiber consumption, frequent lactose malabsorption, parasitosis, and possible overlap between post-infectious IBS and tropical sprue. Moreover, the current perception on difference in prevalence of the disorder in these countries, as compared to the West, might be related to variation in survey methods.展开更多

In this re...The International Consultation on Urological Disease have recently published comprehensive conclusions, based on evidence reviewed by eight committees, on aspects of male lower urinary tract symptoms(LUTS). In this review, we summarise the conclusions from fourof the committees, namely, the evidence regarding the epidemiology of male LUTS, patient assessment, nocturia and medical management. It is indisputable that with an expanding and ageing global population the prevalence of male LUTS is likely to increase. Therefore symptom prevention and preservation of quality of life(Qo L) feature highly in the guidelines. There are now a number of different medical options, proven to lead to significant improvements in symptom scores, flow rate and Qo L available to men with LUTS. Metaanalyses have shown the benefits for alpha blockers, antimuscarinics, 5-α reductase and phosphodiesterase-5 inhibitors. High level evidence also exists for combinations of all of the above with alpha blockers and so men with concomitant storage symptoms, prostate volume > 30 mL, PSA > 1.4 or erectile dysfunction may be considered for combination treatment of an alpha blocker with an antimuscarinic, 5-α reductase inhibitor or phosphodiesterase-5 inhibitor respectively. In an era of personalised medicine, appropriate patient selection is likely to provide the key to the most effective clinical management strategy.展开更多
