Background and Objectives: Hypertension is a global health hazard and most cases are first attended to by the physicians. Achieving a control will depend on the knowledge, attitude and practice of the physicians. We therefore determined the knowledge, attitude and practices of physicians on the detection and treatment of arterial hypertension in north-central Nigeria. Design and Methods: A cross-sectional study of 100 of the 250 physicians attending a continuing medical education lecture series in Bida was conducted using a pre-validated self administered questionnaire. Results: The mean age of the physicians was 41.05 ± 8.71 years and 59 (73.8%) were males. Forty-one (51.2%) of them have practiced for more than 10 years. Arterial hypertension was considered an important health problem by 93.8% of the physicians, 30% of them believed that it should not be referred to a specialist. Majority of the physicians request for urinalysis (96.2%), electrocardiogram (95.0%), fasting blood glucose (88.8%), blood urea nitrogen (98.8%) and fasting lipid profile (97.5%) to either assess target organ damage or associated co-morbid conditions. Fifty-seven (71.2%) of the physicians prescribe diuretics as the initial drug. However, the knowledge of the other drugs on initiation of therapy of mild uncomplicated hypertension was poor. The sources of information on arterial hypertension by physicians were scientific programs (73.8%), drug companies (38.8%) and journals in 11.3%. Conclusion: The knowledge, attitude and practice of physicians in the detection and management of hypertension were modest. Educative programs like continuing medical education, seminars, and conferences on cardiovascular disorders are advised to be organized regularly to strengthen these and update the physicians.

AIM To investigate the efficacy of endoscopic submucosal dissection(ESD) at diagnosing and treating superficial neoplastic lesions of the stomach in a United Kingdom Caucasian *** Data of patients treated with or considered for ESD at a tertiary referral center in the United Kingdom were retrieved for a period of 2 years(May 2015 to June 2017) from the electronic patient records of the hospital. Only Caucasian patients were included. Primary outcomes were curative resection(CR) and were defined as ESD resections with clear horizontal and vertical margin and an absence of lympho-vascular invasion, poor differentiation and submucosal involvement on histological evaluation of the resected specimen. Secondary end-points were reversal of dysplasia at 12 mo endoscopic follow-up and/or at the latest follow up. Change in histological diagnosis pre and post ESD was also *** Twenty-four patients were initially identified with intention to treat. 19 patients were eligible after mapping gastroscopy and ESD was attempted on a total of 25 ESD lesions, 4 of which failed and had to be aborted mid-procedure. Out of 21 ESD performed, en-bloc resection was achieved in 71.4% of cases. Resection was considered complete on endoscopy in 90.5% of cases compared to only 38.1% on histology. A total of 6 resections were considered curative(28%), 5 noncurative(24%) and 10 indefinite for CR or non-CR(24%). ESD changed the histological diagnosis in 66.6% of cases post ESD. Endoscopic follow-up in the "indefinite" group and CR group showed that 50% and 80% of patients were clear of dysplasia at the latest follow-up respectively; 2 cases of recurrence were observed in the "indefinite"group. Survival rate for the entire cohort was 91.7%.CONCLUSION This study provides early evidence for the efficacy of ESD as a therapeutic and diagnostic intervention in Caucasian populations and supports its application in the United Kingdom.
