We report a reversible liquid-solid transition upon heating of a simple solution composed of a-cyclodextrine (alpha CD), water, and 4-methylpyridine. These solutions are homogeneous and transparent at ambient temperature and solidify when heated to temperatures between 45 degrees and 75 degrees. Quasielastic and elastic neutron scattering show that molecular motions are slowed down in the solid and that crystalline order is established. The solution "freezes on heating." This process is fully reversible, on cooling the solid melts...

The authors report a typical case of osteopoikilosis striata Voorhoeve in a 51-years-old female. In connection with case they make some consideration concerning the diagnostic of this very infrequent sclerotic bone dysplasia.

The location of the mega-cell tumours in the inferior extremity of radius is relatively frequent and it represents 10 percent from all mega-cell tumours. The aggressive tumours and the relapsed one must be cut-away. In 3 of the cases which were operated, after a large cutting of the tumour, the author used for reconstruction a grafting from the fibula-bone without vascularisation. The fixing of the focus metallic plates is highly superior to other osteosynthesis. After 3 years, now relapse was remarked. The functional results can be considered good-enough, even some of patients can not perform hard-working...

Starting from the rareness of vertical fractures of the patella, in connection with a clinical case, the authors present this entity and the therapeutical problems in correction with this type of fracture. Interfragmentary diastasis is more than 3 mm, so the authors choose for treatment the osteosynthesis with a spongious screw placed horizontally, perpendicular on the fracture, keeping the integrity of the prepatellar fibrous planes. The authors appreciate that orthopedic treatment is reserved to the incomplete fractures or fractures without displacement...

In connection with 23 different patellar instabilities, the author makes some diagnostical and treatment consideration. The patients were between 18 and 40 years old, 13 women and 10 men. From the clinical point of view there were found 2 simple instabilities, 3 external dislocations, 6 permanent dislocations, 9 relapsed dislocations and 3 of them were habitual. The results in first time were good and excellent in 90 percent. It was a single relapse and by 4 of the patients which have been in watch for five years it was found arthrosis without major functional signs...

Based on their own experience and literature, the authors review the etiopathogenic, anatomo-clinical, diagnostic and management aspects of torso-metatarsal dislocations. The surgical treatment by open reduction or reposition-arthrodesis, as a first or secondary step, using Kirschner wire and staples, are more and more used. The early and late complications, which may aggravate the long-term functional prognosis are detailed.
