Colorectal cancer is the third most common cancer worldwide with a 5-year survival of 50%. Current chemotherapeutic regimens used for advanced colorectal cancer provide an average survival of approximately 20 months. Non-toxic agents such as nutraceutics and supplements have been shown to aid in the prevention and adjuvant treatment of colorectal cancer. This article will discuss the epidemiology, progression, prevention, treatment, and recurrence of colorectal cancer and the role of nutraceutics and supplements in the treatment process.

It is not known if an interaction exists between aspirin and paracetamol in regards to gastroduodenal mucosal injury.

Nitrofurantoin remains the gold standard treatment of uncomplicated cystitis as well as prophylactic treatment of recurrent urinary tract infections. Drug-induced hepatotoxicity presents in acute (3 in 1 000 000) and chronic (1 in 1500) forms. We present a patient with acute liver failure after 5 days of treatment. A 69-year-old man admitted for chronic obstructive pulmonary disease exacerbation 5 days into treatment for cystitis with nitrofurantoin. On admission he was noted to be jaundiced with elevated liver enzymes and normal international normalised ratio. Investigation for infectious, autoimmune and cholestatic causes of hepatotoxicity was negative. The patient improved after discontinuation of the drug and 10 days of methylprednisolone. There are scant data on acute liver failure in the setting of short-term nitrofurantoin administration. The mechanism of toxicity remains unclear, but is hypothesised to be an autoimmune process in which steroids may play a role in treatment. Diagnosis is one of exclusion as the only definitive method of diagnosis is rechallenge.
