Beta-thalassemia represents a range of hemoglobinopathies that are a consequence of an impairment in the synthesis of beta-globin chains. They result in different degrees of hemolysis and ineffective erythropoiesis, depending on the underlying mutations. They can lead to severe complications mainly resulting from anemia. However, there is no bleedi...

Acute appendicitis is perhaps the commonest cause of acute abdomen and surgical intervention in the form of open or laparoscopic appendicectomy [1]. Acute appendicitis is responsible for over 40,000 hospital admissions per year in England, and more than 2,00,000 operations per year in the United States [1,2]. The lifetime risk of having appendiciti...

Lipomas constitute less than 5% of primary brain tumors. Pericallosal lipomas (PCLp) constitute almost half of all intracranial lipomas. Corpus callosal anomalies commonly occur in cases with PCLps. Although PCLp is often described as corpus callosal lipoma, it is most often pericallosal in location. PCLps may have calcification in the periphery an...
