Treatment of anal fissures has changed dramatically in the past decade. This is primarily due to a better understanding of its pathophysiology and the implications of the various available options. Only a few anal fissures fail to respond to medical therapy. Sphincterotomy and anal dilatation have fallen out of favour due to the risk of incontinence. Island flaps have been proposed to address this, but 60-70% of the flap donor sites break down with complications. We propose using a rotation flap to overcome this problem.
Appendicitis has a worldwide prevalence and affects all age groups. The aetiology of acute appendicitis is still much debated, many factors have been implicated. The pathology is likely to be due to obstruction of the lumen of the appendix. Parasites, both helminths and protozoa have been suggested to be the cause of acute appendicitis. Studies have demonstrated that parasites are present in the appendix specimens removed from surgery methods.
A survey of 142 cases of acute pancreatitis was undertaken in two major hospitals serving the state of Kelantan in Malaysia. Females outnumbered males by a ratio of more than 3:1. The incidence among females peaked in the third decade of life. Twenty-one percent (23/109) of the females were pregnant. Ultrasonography revealed gallstones in only 9.4% (13/138). However, abnormalities of serum transaminases were found in 35% (35/100), suggesting that occult gallstones or microlithiasis may be the cause in a significant proportion of patients. Alcohol was virtually absent as an aetiological factor. There was a higher frequency of Ascaris infection in this group than a control hospital population (11/35 vs 33/242; p < 0.02) suggesting that ascariasis may be an important cause of acute pancreatitis in Kelantan. Only 8.4% fell into the category of severe pancreatitis. The overall mortality rate was 2.1%.
