Oxygen-induced retinopathy in the newborn rat: a scoring system for the evaluation of retinal vascular changes. Scoring system for OIR in the rat.
The authors describe a scoring system they have developed for evaluating damage produced in the retinal vascular network of the newborn rat by exposure to oxygen. India ink-injected retinal flat mounts are used. The scoring system provides for division of the retina into three concentric zones with the optic disk as a center point. Each retinal quadrant is then examined for the presence of the following lesions of progressive severity: vaso-obliteration of the capillary network, loss of the periarteriolar capillary-free zone, newly formed capillary tufts. When more than one type of lesion is present in a quadrant, only the most severe lesion is considered. The numerical score corresponding to that lesion is then multiplied by the factor corresponding to the concentric zone in which the lesion lies to give the quadrant score. The total retinal score is represented by the sum of the four quadrant scores. This type of system, if adopted by other investigators, can facilitate precise and systematic description of the results of different experimental protocols.

Effect of light on oxygen-induced retinopathy in the rat model. Light and OIR in the rat.
The purpose of this study was to establish whether exposure to intense lighting favors the development or aggravates experimental oxygen-induced retinopathy in the newborn rat. Five groups of Wistar rats were studied. The control group was maintained for the first 14 days of life under conditions of cyclical (12L:12D) lighting at 12 Lx in room air. Two other groups were subjected, for the same amount of time, to semi-darkness (2 Lx; 12L: 12D), one with room air and the other with supplemental 80% oxygen. The final two groups were exposed to the same room air and hyperoxic treatments under intense lighting conditions (600 Lx; 12L:12D). After the treatment period, four rats were randomly chosen from each group, sacrificed and their retinas examined under electron microscope. Marked structural changes were seen only in the photoreceptor outer segments of those rats exposed to intense light. In eighty-five of the remaining rats retinal vascular morphology was examined in retinal flat mounts after intracardiac injection of India ink. Retinopathy was observed in rats treated with hyperoxia but no significant differences could be attributed to the light conditions under which the retinopathic rats had been maintained. In the rest of the rats, axonal transport along the optical pathways was evaluated after intravitreal injection of (3H) taurine. In the two groups exposed to hyperoxia, axonal transport was altered, but less markedly in those exposed to intense lighting than in those exposed to semi-darkness. Intense illumination under conditions of normoxia favors axonal transport. Exposure to intense lighting does not seem to aggravate oxygen induced retinopathy in the rat though it does produce structural lesions of the photoreceptors.

[Surgical treatment of Crohn's disease complications. Our experience].
Thirty-five patients with Crohn's Disease (CD) were observed: 18 have been treated with medical therapy and 17 (48.6%) underwent to surgical treatment : 1) intolerance to the medical treatment in 5.9% (1 case); 2) local complications in 94.1% (16 cases: 6 stenosis, 2 occlusions, 3 abscesses, 3 fistulas, 1 perforation with peritonitis, 1 case toxic megacolon). The operations have been 19: resective interventions 14 (bowel and/or colon resections), conservative interventions 5. The mortality was 0, the morbidity 35,29%. The incidence of the recurrences in a follow up of 5 year was 42,9%. The Authors conclude that the surgery, indicated for the treatment of complications, can be resective surgery (perforating Crohn disease: fistulas, abscess) or conservative surgery (stenosing Crohn disease: stenosis). Recently the conservative intervention are proposed in the treatment of fistulas and abscesses too, but when the inflammation is mild and in patients that underwent to extensive intestinal resection with risk of short bowel syndrome.

[Excision of a schwannoma of the neck: surgical technique].
We present a case of schwannoma of the neck in 49 year old man, symptomatic (paresthesia, cervical mass and dysphagia). After ultrasonography and magnetic resonance of the neck, the patient was operated and excision of the lesion was completely performed. The operation was performed through a cervical approach: the nerves and the vascular and muscular structures were carefully isolated and preserved. The tumour arised from the cervical sympathetic chain. The diagnosis of schwannoma was possible only by histopathologic examen. After 48 months no local recurrence or postoperative complication related to intervention were found. These lesions are uncommon. The identification of the nerve is often difficult until the operation, which is the treatment of choice for the schwannoma.

[Characteristics of Italian thermal parks and gardens: explorative study; therapeutic possibilities. I].
There are reported the results of a research about thermal parks and thermal gardens own to 27 italian Spas. The considerable areas of green around Spas, the correct ratio with the number of subjects in thermal treatment and others arguments represent favourable elements for italian Medical Hydrology. The importance of green around Spas in Thermal Medicine and in Ecology il stressed.
