RESUMO
Many reposts had suggested that copper and zinc may reflect diseases activity in lymphoma. Also, zinc helps in the function of WBCs in immune system. Whole blood samples were taken from 6 healthy donors and 10 patients suffering from different types of cancer. Serum copper and zinc were measured by using XRF method. Serum copper of cancer patients is higher than that of controls [P < 0.05] while serum zinc concentration is lower in patients than that of controls. Therefore, these two elements can be used as additional tests in diagnosis and managing cancer patients

This report concerns the study of 266 eyes [259 patients; age range 3-83 years] with retinal detachment [RD] over a 7 year period. The condition was more frequent in males [76%], and appeared to increase with age since more than 60% of cases were more than 41 years old. Furthermore, older myopics were at higher risk of sustaining RD, and this risk was also associated with the degree of myopia. The total number of cases with myopia was 125 [47%], aphakia 51 cases [19%], RD due to lattice degeneration 38 cases [14.3%], traumatic RD 35 patients [13%], tractional RD 8 cases [3%] of proliferate diabetic retinopathy, and a further 9 cases [3.6%] were due to uveitis. Preoperatively, 75.5% of patients were in the counting fingers category, whereas postoperatively only 48% had this degree of visual loss

The study included 329 patients with ocular trauma whose ages ranged from 4 to 60 years [median 17.6 years]. The number of males was 316 [96%] and of females 13 [4%]. The right eye was affected in 191[58%] cases and the keft in 138 [42%]. In 190 cases [58%] the cause was blunt trauma which precipitated hyphaema. Another 114 cases [34.4%] were due to perforated ocular wounds. Finally, 25 cases [7.6%] were found to have intra ocular foreign bodies. A substantial proportion of these patients developed serious complications, of which cataract, that occurred in 160 [48.6%] patients, was the most common. Those occurring less frequently were vitreous haemorrhages 23 [7.6%], retinal detachments 21 [6.4%] and traumatic macular changes 7 [2%]. In addition, there was 5 cases that developed glaucoma and 3 endophthalmitis cases
