ABSTRACT
The occurrence of room temperature ferromagnetism is demonstrated in pulsed laser deposited thin films of Sn(1-x)Co(x)O(2-delta) (x<0.3). Interestingly, films of Sn(0.95)Co(0.05)O(2-delta) grown on R-plane sapphire not only exhibit ferromagnetism with a Curie temperature close to 650 K, but also a giant magnetic moment of 7.5+/-0.5 micro(B)/Co, not yet reported in any diluted magnetic semiconductor system. The films are semiconducting and optically highly transparent.

The authors report a case of a 93-year-old man with villous adenoma causing acute phlegmonous appendicitis. The appendicular localization, extremely uncommon, is the cause of an acute appendicitis in 50% of cases. Therefore, they analyse the anatomo-pathological, clinical, diagnostic and therapeutic aspects of this pathology with the help of the literature.

Primary torsion of the greater omentum is an uncommon cause of acute abdomen and frequently it is misunderstood. In fact, from the analysis of the literature the authors can evict that the preoperative diagnosis is generally wrong. The authors write about the subject and they describe four cases come to their observation and all mistaken for acute appendicitis.
