[Ocular phototoxicity and altitude among mountain guides].

Purpose: This study aimed to evaluate ocular phototoxicity in mountaineer guides who experience overexposure to ultraviolet related to the altitude at which they work, as well as light reflection on snow.

Materials And Methods: Ninety-six guides and 90 controls living in plains, over 50 years old, underwent complete examinations. They responded to a questionnaire assessing altitude exposure and protective eyewear.

[Comparison between Lenstar LS 900 non-contact biometry and OcuScan RXP contact biometry for task delegation].

Introduction: Non-contact biometers have many advantages including the delegation of tasks to orthoptists. This study analyses the reliability of measurements comparing contact and non-contacts techniques.

Patients And Methods: Comparative measurements were taken on 86 eyes of 45 patients (mean age: 74 years; 44.

[Susac syndrome: variable onset modes and disease courses: two case reports].

Introduction: Susac syndrome is a rare microangiopathy of unknown etiology, which involves the clinical triad of encephalopathy, visual loss, and hearing loss. Several onset and progression patterns are possible.

Observation: Case 1: a 43-year-old woman developed subacute encephalopathy, which had not been diagnosed and had been evolving for 2 months, as well as left sensorineural hearing loss.

[Isolated occlusion of a cilioretinal artery].

Purpose: Isolated cilioretinal artery occlusion is uncommon but has characteristic features. Based on a case report and a review of the literature, we present the clinical findings and angiographic particularities of this syndrome and discuss controversial pathophysiological data.

Case Report And Method: A 56-year-old man had sudden visual loss in the right eye estimated at 3/10 P10.

[Fracture of the odontoid process (author's transl)].

102 cases of fractures of the odontoid process have been seen by the author - 73 recent cases and 29 old ones. It was important to distinguish basal fractures (29 cases), which all united after conservative treatment by reduction and skull traction for six weeks followed by a plaster cast for six to eight weeks, and fractures of the body (44 cases). 41 body fractures were treated conservatively, of which 6 died and only 20 united.

[Blind nailing of trochanteric fractures using the Ender method (author's transl)].

After trochanteric fractures, the rate of survival of old patients was best when treated by the Ender method: 15% died during 3 months following the fracture. The procedure is uneasy and an excellent radiologic technique is necessary. The position of the proximal end of the first nail in the femoral head is most important.

[Lumbar venography in the diagnosis of disc herniation (author's transl)].

The authors have performed lumbar venography on 120 occasions in patients with low back pain. In 58 patients in whom the herniated disc was confirmed, the result of venography was positive and the localisation was precise in 67 cases. It is concluded that the method is safe, reliable and allows precision in diagnosis to allow better selection for surgical treatment.

[The radioimmunological assay of fibrinogen breakdown products with E antigen during postoperative venous thromboses. Study in 46 cases of arthroplasty for osteoarthrosis of the hip (author's transl)].

Twenty six patients (without thrombosis) had a normal 125I-fibrinogen test, among whom 15 had a normal phlebography; 18 patients (with thrombosis) had a positive 125I-fibrinogen test among whom 11 had a positive phlebography. There was a discrepancy between phlebography and 125I-fibrinogen test in 2 patients. In patients with thrombosis, there is a significantly increase of FgE levels for several days after the intervention.

[Combination of methylmethacrylate (acrylic cement) and antibiotics. Bacteriologic and mechanical study].

The authors report the results of a study about the association of acrylic cement with antibiotics. Three cements have been tested: Simplex, CMW, Palacos, with 14 different antibiotics. A series of experiments has been carried out in three phases: a macroscopic study of the polymerisation of the mixture; in vitro bacteriological studies; and mechanical studies (trials of resistance to traction, flexion, shock measuring the modulus of elasticity and hardness).
