Purpose: To evaluate primary intraocular lens implantation in the treatment of children's aphakia in the Brazilian public health system and compare the outcomes among different age groups.

Methods: Children aged 0-12 years old with unilateral or bilateral congenital/developmental cataracts and underwent primary intraocular lens implantation were included.

Results: A total of 108 eyes from 68 children were evaluated, and the children were divided into four age groups (<7 months [mo]; 7 mo-2 years old [y/o]; 2-5 y/o, and >5 y/o) were evaluated.

Objective: To report the outcomes and complications of colored soft contact lenses (SCLs) to improve esthetic or eye function in visually impaired (VI) or blind patients.

Methods: This retrospective study enrolled consecutive patients with unilateral or bilateral VI or blindness who had received colored SCLs to improve appearance or ocular function. Data were collected on demographics, complaints, complete ophthalmological examinations, types of SCL, follow-ups, and complications.

Purpose: To evaluate the ocular axial length (AL) and keratometry (K) in Brazilian children with congenital/developmental cataract, assess the differences and evolution of AL and K according to age, and establish functional models of AL and K as function of age.

Methods: Children with congenital/developmental cataract aged 1.5 months old to 8 years old and no other ocular diseases were included.

Objective: Saphenous vein grafts (SV) used in coronary artery bypass grafting have a limited life and vein occlusion may be the final adverse effect. Efforts to develop new techniques to harvest the saphenous vein may improve the viability of the graft.

Methods: Twenty patients were randomly divided into two groups with the objective of evaluating the vascular endothelium.

Objective: A retrospective study was performed in a series of consecutive patients who underwent a Bentall and De Bono procedure.

Methods: Data were removed of medical records and follow-up data were obtained from clinical records and direct contact with patients. A total of 39 patients were studied between January 1996 and December 2005.

Physiological parameters of laboratory animals used for biomedical research is crucial for following several experimental procedures. With the intent to establish baseline biologic parameters for non-human primates held in closed colonies, hematological and morphometric data of captive monkeys were determined. Data of clinically healthy rhesus macaques (Macaca mulatta), cynomolgus monkeys (Macaca fascicularis), and squirrel monkeys (Saimiri sciureus) were collected over a period of five years.

The long-term management of breeding colonies requires some measure of genetic diversity in the animal population. For the maintenance of breeding colonies of monkeys used for biomedical research, known pedigrees supply precise data to determine the genetic status of colonies. We present data of genetic analyses in an old closed colony of rhesus macaques (Macaca mulatta) that was established in 1932 with 100 animals.
