cis-Dichlorodiamminepltinum(II) in adult patients: Southwest Oncology Group Studies.

In addition to cis-dichlorodiammineplatinum(II) studies in lymphomas and testicular cancer and a broader phase II study of all genitourinary malignancies, the Southwest Oncology Group is currently conducting eight other studies which examine the effectiveness of this drug in adult patients with a variety of tumor types. This report will give preliminary analyses of the five studies for which there are early data, plus briefly describe the design of the three remaining protocols for which there are no data as yet.

[Retinopathy of prematurity and immaturity . A clinical study].

The retinopathy of prematurity is the most important cause of blindness at children and one of the most frequent cause of blindness in the postnatal period. 435 newborn prematures and dismatures, were examined in the first two weeks since they were born. The ophthalmological exam showed vasoconstriction of retinal vessels. The treatment consisted in cryotHerapy with good results. The most up-to-date method is the therapy with argon laser mounted on the indirect ophthalmoscope.

[Reconsideration of the stages in the maturation of visual function in children].

The ocular globe is incompletely developed at the time of birth. The majority of sensorial and motor visual functions differentiate specifically after birth, in a certain chronology. The study of the visual function of the just-born child was based especially on the exams of reflexes, of the ocular globes motility, on the morphological aspect of the ocular globes and on the exam of the eye fundus, the exam of the visual acuity using preferential look (PL), and visual evoked potentials (VEP). The fact that the development of the visual function is directly dependent by the visual experience was emphasized. So the treatment of any ocular disease, which is manifest at bith-time or immediately after birth and which is disturbing the vision, must be done correctly and as soon as possible.

[Strabismus determined by anatomical changes in the extrinsic ocular muscles].

The anatomical primitive strabismus is prenatal and its characteristic is the loose in the elasticity of the muscles of the surrounding tissues. The cause is the deficit of embryogenesis, originating in the first two months of pregnancy. They are presented the clinical cases of anatomical strabismus, investigated and treated in the Ophthalmological Clinic during 10 years, the surgical techniques used and the postoperative functional and obstetrical results the ocular disturbances are intense and the debut is early. The surgery involves both eyes and the results depend on the clinical form, the restant ocular motility and the degree of fibrosis of the affected muscle.

[The loss of a right muscle in the orbit intra- or postoperatively].

One child four and half years old remains with a divergent deviation by forty-five degree with absence of adduction, after an operation of convergent strabismus at the left eye. Considering that is about by one postoperatorial paralytic strabismus, computer tomography praises the right intern muscle retracted at the back of orbit, but it doesn't adheres at the eyeball. It considers that the divergent strabismus was caused by the slide of postoperatorial muscle. Looking middle line of the muscle, parallel with the middle wall of the orbit, it praises the right intern muscle retracted and after the excision of the granulation tissue all round, displays the muscle with its normal lenght. It cuts 3.5 milimeters from this muscle and it practices the retroposition of the extern right muscle with 7 milimeters. It obtains postoperatorial orthophoria. It talks about possibility of lossen of a right muscle in orbit intra- and post-operatorial and the measures that are imposed in these situations.
