Importance of psychological intervention for the recovery of children submitted to elective surgery

Purpose: The effects of anxiety on the patient and his/her family are known to be the main factors that influence health recovery in child surgery. When the whole family can be prepared and supported by psychologic intervention, the damage to child behavior and family anxiety is attenuated. Methods: This study was conducted in children between 2 and 6 years old, divided into 2 groups of 10 pairs each. The experimental group received psychologic intervention, whereas the control group did not. One month after the surgery, they were reevaluated and compared with the same instruments used in the beginning of the study. The instruments used were as follows: the State-Trait Anxiety Inventory with the mothers and the Rutter`s Child Behavior A2 Scale and the Posthospital Behavior Questionnaire with the children. Results: The results were compared by the Wilcoxon and Mann-Whitney nonparametric tests for independent samples, both at the P <.05 significance levels. Mothers stated that anxiety was different in the postsurgery period, showing a significant decrease when comparing the experimental and control groups. Both instruments to measure child behavior also showed that prepared children had less habit changes than the control group, which showed increased levels of inadequate behavior. Conclusions: These data confirm reports in literature regarding child preparation before medical intervention and reinforces the importance of specialized presurgery planning procedures by the proper professional interfaced with the surgical colleagues, all aiming toward the best recovery for the children.

Organophosphate-related ototoxicity: Description of the vestibulocochlear system ultrastructural aspects of guinea pigs

Organophosphate toxic agents are used in agriculture and are currently part of the group of toxic agents which can lead to hearing loss, in which we have solvents, metals and asphyxiation agents. Aim: to analyze the acute ototoxic action of a group of organophosphate agents in the vestibulocochlear system. This is a prospective experimental study. Materials and Methods: we used male albino guinea pigs, broken down into three groups, to which we provided distilled water (group 1 - control), agrotoxic agent - 0.3mg/Kg/day (group 2), agrotoxic - 3 mg/Kg/day (group 3), during 7 seven consecutive days. The most used agrotoxic agent was Tamaron BR (metamidophos). The anatomical evaluation of the cochlea, saccule and utricle was carried out by means of electronic scanning microscopy after the use of the agrotoxic agent. Results: the guinea pigs submitted to the organophosphate presented cochlear morphological alterations with lesions on the three turns analyzed, as well as cilia alterations in the saccule and utricle, intensified according to the agent dosage. Conclusion: the morphological alterations seen in the hair cells exposed to daily doses of organophosphate promote evidences of an acute deleterious effect of agrotoxic agents on the vestibulocochlear system.

Epidemiologic aspects and clinical outcome of fungal keratitis in southeastern Brazil

PURPOSE. Fungal keratitis (FK) is a sight-threatening disease, more prevalent in developing regions. The present retrospective study was conducted in order to evaluate the epidemiologic and clinical aspects and the progression of FK in patients treated at two ophthalmologic reference centers in Southeast Brazil. METHODS. The charts of patients with infectious keratitis treated between 2000 and 2004 were reviewed. For the 66 cases of FK confirmed by microbiological analysis, data related to patient, disease, and therapeutic approaches were obtained. RESULTS. Mean patient age was 40.7 +/- 16 years. Fifty-three were men and 13 were women. Ocular trauma occurred in 40% of cases (27). Previous medications taken by the patients were quinolone in 72.5% and antimycotics in 30%. Visual acuity (VA) at presentation was >0.3 in 16% and <0.1 in 74.5%. Penetrant keratoplasty was performed in 38% and evisceration in 15%. The causing agents were Fusarium sp in 67%, Aspergillus sp in 10.5%, and Candida sp in 10%. Medication alone resolved 39% of cases within a mean period of 24.5 +/- 12 days. Final VA was >0.3 in 28%, and <0.1 in 63%. CONCLUSIONS. Fungal keratitis presented as a disease with severe complications, predominantly among young males, and was mostly caused by filamentous fungi. The present information permits the establishment of preventive strategies. Reducing the time between onset and treatment and using more accessible specific medication would reverse the negative prognosis. (Eur J Ophthalmol 2009; 19: 355-61)

Dry eye in childhood: Epidemiological and clinical aspects

Because dry eye disease is rare in children and its pathogenesis is less well known than in adults, its diagnosis is often overlooked. It can occur in association with a number of congenital, autoimmune, endocrine, and inflammatory disorders, or under certain environmental and nutritional conditions. In some cases, early detection allows the underlying cause of the dry eye to be successfully treated and eliminated. In other cases, the disease may represent a lifelong problem, whose proper management can prevent ulceration and scarring of the ocular surface. Because of the association of pediatric dry eye with other conditions, a multidisciplinary approach to diagnosis and treatment is usually required. The purpose of this review is to enhance physician awareness of dry eye in children, to describe the most frequently associated conditions, and to discuss the diagnostic and therapeutic options available.

Anxiety and Depression in Mothers of Preterm Infants and Psychological Intervention During Hospitalization in Neonatal ICU

The objective of this study was to evaluate and compare symptoms of anxiety and depression before and after psychological intervention in mothers of babies born preterm with very low birth weight, hospitalized in the Neonatal Intensive Care Unit. Fifty nine mothers, without psychiatric antecedents, were distributed into two groups according to the type of psychological intervention received. Group G1 included 36 mothers who received routine psychological treatment associated with initial structured intake using support materials (video and guidance manual). Group G2 included 23 mothers who received routine psychological intervention without support material. The STAI and BDI, respectively. were used to evaluate maternal indicators of anxiety and depression. The results revealed that both groups showed a reduction in levels of state or trait anxiety and depression after psychological intervention and discharge of the baby from the hospital. In regard to the emotional symptoms at a clinical level, a statistically significant reduction in the level of state-anxiety was verified in G1. The findings confirmed the need for psychological support for mothers of preterm infants and the use of materials focusing on ""prematurity"" for reduction of the situational anxiety on a clinical level.

Aspects of adaptive management of coastal wetlands: Case studies of processes, conservation, restoration, impacts and assessment

Coastal wetlands are dynamic and include the freshwater-intertidal interface. In many parts of the world such wetlands are under pressure from increasing human populations and from predicted sea-level rise. Their complexity and the limited knowledge of processes operating in these systems combine to make them a management challenge.Adaptive management is advocated for complex ecosystem management (Hackney 2000; Meretsky et al. 2000; Thom 2000;National Research Council 2003).Adaptive management identifies management aims,makes an inventory/environmental assessment,plans management actions, implements these, assesses outcomes, and provides feedback to iterate the process (Holling 1978;Walters and Holling 1990). This allows for a dynamic management system that is responsive to change. In the area of wetland management recent adaptive approaches are exemplified by Natuhara et al. (2004) for wild bird management, Bunch and Dudycha (2004) for a river system, Thom (2000) for restoration, and Quinn and Hanna (2003) for seasonal wetlands in California. There are many wetland habitats for which we currently have only rudimentary knowledge (Hackney 2000), emphasizing the need for good information as a prerequisite for effective management. The management framework must also provide a way to incorporate the best available science into management decisions and to use management outcomes as opportunities to improve scientific understanding and provide feedback to the decision system. Figure 9.1 shows a model developed by Anorov (2004) based on the process-response model of Maltby et al. (1994) that forms a framework for the science that underlies an adaptive management system in the wetland context.

Ultrasonographic aspects and biometry of Striped owl`s eyes (Rhinoptynx clamator)

Objective To report the biometric values and ultrasonographic aspects of the normal eye of the Striped owl (Rhinoptynx clamator). Sample population Twenty-seven healthy, free-living, adult Striped owls from the Ecological Park of Tiete Veterinary Ambulatory (Sao Paulo, Brazil). Procedures Both eyes of all owls underwent B-mode ultrasonographic examination and biometry was performed for lens axial length (WL), depth of the anterior (AC) and vitreous (VC) chambers, axial length of the globe (LB) and the pecten oculi (LP) of both eyes, using a 12 MHz probe. The owls were manually restrained without sedation and the eyes were topically anesthetized. Results Biometric and statistical findings were as follows: in the left eye, the means and standard deviations were: LB = 23.76 +/- 0.92 mm, WL = 7.79 +/- 0.27 mm, AC = 4.27 +/- 0.47 mm, VC = 11.36 +/- 0.29 mm and LP = 5.69 +/- 0.50 mm; in the right eye, the values were: LB = 24.25 +/- 0.79 mm, WL = 8.03 +/- 0.40 mm, AC = 4.56 +/- 0.52 mm, VC = 11.40 +/- 0.25 mm, and LP = 5.68 +/- 0.41 mm. No significant differences were found between left and right eyes measurements of LB, WL, AC, VC, and LP dimensions. Conclusions Ocular ultrasound aspects and biometric values of the Striped owl are reported. The study`s results provide means for various ocular measurements. The ultrasound is an easy and safe exam to be performed in the Striped owl`s eyes.

Ultrastructural aspects of lingual papillae in squirrel monkey (Saimiri sciureus)

Saimiri sciureus is one of the smallest Cebidae native of Amazon region and also found at the biological reserve of northeast Atlantic forest. It is an omnivore animal, with diversified diet that directly influences the lingual mucosa, which includes certain types of papillae with different organization levels. The present study attempted to describe the morphological and ultrastructure aspects of the dorsal surface of the S. sciureus. Five tongues of de S. sciureus were analyzed from three males and two females who died from natural causes and were obtained from breeding colonies of CENP-Ananindeua-PA. Main macroscopic features were a general triangular shape with a craniocaudal elongation pointed apex. Tissue samples-apex, body, and root of tongue-were fixed in modified Karnovsky solution, following standard scanning protocol, mounted in stubs, coated by gold, and analyzed by Scanning Electron Macroscopy (SEM). Four types of papillae were described: filiform (along all tissue extension with 154 mu m of diameter), fungiform (along all tissue extension with 272 mu m of diameter), vallate [just three units in caudal (dorsal) portion with 830 mu m of diameter] and foliate (one pair at caudolateral surface with similar to 13 projections and 3000 mu m in length). Data analysis indicates that the distribution and ultra structural morphology of the S. sciureus lingual papillae are some similar to other primates. Microsc. Res. Tech. 74:484-487, 2011.
