[Skin graft protection by treatment of recipients with ultraviolet irradiated fragments of the donor spleen].

We have tested de possible protective effects of UVA radiated spleen fragments upon simultaneous skin allografts in 84 rats. Under these circumstances skin graft rejection was less evident with a 20 day graft disappearance rate of 46.87% rate in the treated series, that compares favourably with a 80% in the control series. This study shows a parallel increase in the mean survival time of skin grafts in treated specimens. The figures being 19.8 days in the treated series against 12.9 days in untreated controls. Spleen implants are finally shown to produce a healing stimulus in the skin graft zone. These differences are statistically significant.

[Retinoblastoma: review of 19 cases].

A retrospective study of retinoblastoma was done during 1978-1987, analysing the clinics aspects of the entity. We found nineteen children during this period, from them eight were girls (42%) and eleven were boys (58%). Ages of diagnostic ranged between three months and four years, with and average of 17.53 months. Nine children (47%) were bilaterally affected. Leocokoria was the most common initial sign, followed by strabismus. Ophthalmoscopy was the diagnostic procedure used, and surgery the recommended therapeutic, using radiotherapy as a palliative method in the cases which surgery has no indications.

[Efficacy of the CO2 laser in partial glossectomies].

In the present work, the authors show their experience in tongue surgery with Co2 laser. Two different kinds of partial glosectomies were made in several cases, CO2 laser was used on the right side, and conventional methods on the left side as a comparative group. Histological studies were made between both sides, in order to find differences in normal hemostasy and tissue response.

[Morphological bases of oncology].

The author makes a review of the morphological bases of oncology, considering the methods used in pathological anatomy, the data obtained from histopathology and ultrastructure of neoplasms, and the morphological criteria useful for prognosis.

Myxoma of the jaws. Report of three cases.

Odontogenic myxoma is a locally aggressive, uncommon benign tumour which arises from mesenchymal tissues normally present in developing teeth. The most frequent locations of odontogenic myxoma are the posterior regions of the mandible, as well as the condylar region. Since odontogenic myxomas are not associated with any specific clinical or radiological sign, a histopathological examination of the specimen is required for confirmation of the primary diagnosis. We report three cases of myxoma diagnosed during the last 18 years. Two of them were located in atypical regions of the mandible and one was located in the maxilla. Presence of a slow-growing swelling associated with expansion of the bone plates raised suspicion of a tumour in two cases, while in the third patient the myxoma was an incidental finding during radiological examination. Due to the unspecific nature of these lesions, in every case a histopathological examination of the surgical specimen was required for diagnostic confirmation. In one of the three reported cases, we shall underline the need to follow a correct diagnostic work-up of all radiolucent lesions of the jaws, in order to avoid contraindicated therapeutic procedures.
