Anatomical aspects of the lacrimal gland of the tufted capuchin (Cebus apella)

In the tufted capuchin (Cebus apella) the main lacrimal gland is composed of 2 distinct portions with an intraorbital and extraorbital localisation, interconnected by a bridge of glandular tissue which crosses the lateral orbital wall through the lateral orbital fissure located in the sphenozygomatic suture. The intraorbital lacrimal gland is flattened and extremely thin, with a variable outline. It lies on the upper and outer third of the globe of the eye, and the aponeurosis and the belly of the lateral rectus muscle, extending antero-posteriorly from the upper lateral angle of the orbit midway along the orbital cavity. The extraorbital lacrimal gland is compact, halfmoon-shaped, with 3 surfaces, 3 borders and 2 extremities. It lies in the temporal fossa between the temporalis muscle and the temporal surface of the zygomatic bone, fitting into a depression in this bone, and totally surrounded by adipose tissue. The secretory cells have a flocculent appearance and either low or high density. They possess a basal region containing the nucleus and rich in granular endoplasmic reticulum, and an apical region filled with secretory granules varying in size, form and density.

Evaluation of lacrimal system outflow in the newborn by dye tests

PURPOSE: The aim of this study was to evaluate the outflow from the lacrimal excretory system (LES) at birth. METHOD: Two-hundred LES were evaluated by the Milder Test (DDT) and the modified Jones I Test (JIT) in 100 newborns (NBs) from 31 (T 1) until 42 (T 3) weeks of gestational age. The occurrence of obstruction was related to sex, weight at birth, presence of ocular discharge and the degree of maturity. RESULTS: Both tests were in agreement and showed LES obstruction in 61.5% (DDT) and 78.5% (JIT), respectively, while the LES outflow increased with increasing maturity. CONCLUSION: Evaluation of LES outflow at birth reveals obstruction rates that are much higher than those clinically observed in children with complaints of epiphora.

Cinedacryocystography in the diagnosis of lacrimal obstruction in children

Purpose: To analyze the cinedacryocystography in children with congenital nasolacrimal obstruction suspicion. Methods: The cinedacryocystographic examination was done in 143 children (58% of girls and 42% of boys) younger than 5 years old, suspected of congenital nasolacrimal obstruction. The exams were done under general anesthesia and the children were probed immediately when obstruction was detected. Results: Epiphora, discharge or both were the most common complaints. Nevertheless 11% children had undergone unsuccessfully probing once, no one had any radiologic evaluation previously. The cinedacryocystographic exam showed nasolacrimal duct obstruction in 65,73%. Permeable lacrimal vies were presented in 34,3% of the children with epiphora. The obstruction was mainly at the Arlt's sinus. Using the cinedacryocystography, it was possible to observe the lacrimal sac enlargement and alterations in the contiguous structures such as hypertrophic turbinates (91,1%), sinusitis (44,6%) and septum deviation (24,1%). Conclusion: Cinedacryocystographic evaluation provides important information about lacrimal system obstruction in children, therefore, it is useful in all children with suspected congenital lacrimal obstruction.

APR e FMEA em trocador de calor de bomba

The modernization of the world made the speed, accuracy and reliability of all existing processes become increasingly necessary. For this evolution to occur every day, the evolution of the equipment was strategic, but not as much as needed. It is necessary for such equipment to ensure its function and, in case of failure, an early diagnosis to prevent loss. Therefore the evolution of maintainability and reliability in equipment is also paramount. Thus, the growth of forms of maintenance was driven by this scenario, forming maintenance philosophies. Among many, there is the RCM, which have its focus on the identification, parameters development and performance preview. One of those methodologies from this idea is the FMEA, process that has been studied and implemented this work, aiming the anticipation of failure modes and guidance for the use of a heat exchanger and a pump. This implementation has the aid of another process of RCM, the PHA, which was also shown and implemented, these results being used to start the FMEA process. The results show the activities with the highest chance of failure, presenting also the measures to be taken to avoid or minimize them. It is shown, in this paper, concern with the valves because they maintain control and system security, and its flaws related to accidents with possible danger to people and the whole system, emphasizing the priority of action
