Thirteen cases of osteoid osteoma and nine cases of osteoblastoma are reported. Diagnostic difficulties of osteoblastoma are illustrated by the versatile radiographic appearances of this tumour. The authors stress the importance of nuclear scan and CT in diagnosis and management.

To our knowledge, the response to lamotrigine in HH cases has never been reported. Because of its safety profile and availability, lamotrigine can be an effective alternative treatment in HH.

A lot of magnetic measurements are accomplished in order to improve the phase diagrams of the systems Zn, -,Cd,Cr,S, and Zn, -,Cd,Cr,Se, particularly in the region of intermediate concentrations with mixed structure. The exchange integrals for the first and second coordination spheres ( J and K ) are calculated in terms of dilution for the three systems Zn, _,Cd,Cr,Se,, Zn,-,Cd,Cr,S,, and Zn, -,Hg,Cr,Se,. The evolution of the structure and the magnetic properties with the substitution of diamagnetic ions at tetrahedral sites is the result of the competition between the ferromagnetic and antiferromagnetic interactions. Besides, the magnetic properties are compared with the phase diagrams (T, x) of these systems. Because of its complicated antiferromagnetic structure, the sulfur compound seems to have particular characteristics among the mixed spinel systems.
