Oesophageal ulcer due to a herbal remedy.

Herbal-induced oesophageal lesions are rare. We report the case of an 85-year-old male who presented with cough and odynophagia. An upper endoscopy showed white deposit under the proximal oesophageal sphincter. Biopsy of the lesion revealed an oesophageal ulcer with adherent plant material and ruled-out candidiasis. At this point, the patient divulged self-preparation of an herbal remedy consisting of Aloe Vera pulp, whisky, honey, ginger and turmeric. Aloe Vera, ginger and turmeric are commonly used to sooth some gastroenterological symptoms in Complementary and Alternative Medicine. Incorrect extraction of Aloe Vera pulp and adding honey to it transformed the recipe into a sticky paste that may have injured the oesophageal mucosa. Follow-up showed that the cough and odynophagia subsided after discontinuing this herbal remedy.

Association of Streptococcus bovis endocarditis and advanced colorectal neoplasia: a case-control study.

OBJECTIVE: To study the association between Streptococcus bovis (S. bovis) endocarditis and advanced colorectal neoplasia. METHODS: This was a case-control study of patients with S. bovis endocarditis undergoing colonoscopic evaluation. Patients were matched 1:20 with controls by gender and age (±2 years) from a large screening colonoscopy database. The baseline, colonoscopic and clinicopathological characteristics of patients with S. bovis endocarditis were analyzed. RESULTS: From 1996 to 2010, 18 adult patients with S. bovis bacteremia were identified, of whom 10 with infective endocarditis (IE) underwent colonoscopic evaluation. Endocarditis involved a native or prosthetic valve in six and four of those patients, respectively. All 10 patients recovered without recurrence of IE (mean follow-up duration 49.6 months). None had a concurrent or preceding history of colon disease and only one had subclinical chronic liver disease. Advanced neoplasia, defined as the presence of polyps ≥1 cm (n = 6), villous histology (n = 3), high-grade focal dysplasia (n = 1) or cancer (n = 1), was found under colonoscopy in 6 of the 10 cases (60.0%) compared with 13/200 (6.5%) matched controls (OR 21.6, 95% CI 5.4-86.1, P < 0.0001). CONCLUSIONS: S. bovis endocarditis is strongly associated with the presence of advanced colorectal neoplasia. In the absence of any contraindication, colonoscopic examination is strongly recommended in patients with endocarditis. The exact pathophysiological mechanisms underlying this association and the predilection for S. bovis bacteremia in patients with advanced colonic neoplasia remain unclear.
