Full textThe human lens has two functions to fulfil. It has to transmit light and it has to change its shape according to the requirements of the accommodative process. These functions are determined respectively by the optical and mechanical properties of the lens. It is well documented that cataracts contribute to the gradual changes of the lens matrix properties. The fact is that loss of transparency due to cataract is a universal phenomenon occurring in 70% of the population over 70 years of age and that the only effective treatment for cataracts is its operative removal. In cataract surgery, anterior capsulotomy is a highly defined and crucial procedure. It involves creating a circular opening in the lens by incising the anterior surface of the lens capsule. This gives access to the lens cortex which is then extracted and replaced with a permanent plastic lens. The most popular capsulotomy technique involves tearing the capsule in a circular fashion using forceps. However, there are many potential problems to this technique such as: it is difficult to master, it takes a long time to perform and above all, it runs the risk of creating tears on the periphery of the opening. Since the capsule is retained post-operatively and acts as a support and centralisation of the artificial lens, it is necessary that the integrity of the capsule remain intact. Since anterior capsulotomy is an unpredictable procedure in cataract surgery, there is a definite need for a surgical device that can perform a reliable incision on the capsule. Using ultrasound to perform a capsulotomy is an innovative technique and its application has to be thoroughly investigated. The investigation includes a numerical and experimental analysis of the lens capsule. The numerical analysis shows that the lens capsule reaches states of resonance at frequencies above 80 kHz. It is at resonance that the capsule oscillations are increased and the cellular bonds are strained and broken. Attempts were made to perforate the human lens capsule using experimental piezoelectric transducer systems operating at resonance frequencies of 81.6, 106 and 187 kHz. Although each ultrasonic system was able to denature the lens cortex, a perforation of the lens capsule was only achieved at a frequency of 81.6 kHz. However, the perforation was irregular and exhibited several tears. This result is not acceptable as one of the main design requirements is to produce a capsulotomy that has a smooth and continuous margin. The amplitudes for the higher frequencies were inadequate to strain and break the capsule, even when the crystals were driven at their maximum voltage of 400 Volts. The present investigation proves that it is highly unlikely that an ultrasonic tool can be designed within a safe margin of frequencies and voltages. As long as no other alternative method is devised, surgeons will have to contend with the occasional complication of radial tears that occur during anterior capsulotomy using current anterior capsulotomy techniques.

Full textObsessive-Compulsive Disorder (OCD) is a chronic disease characterized by the presence of obsessions and/or compulsions. In general, about 20% of OCD patients are considered refractory for not responding to multiple first-line treatment interventions. Performing surgical procedures such as gamma ventral capsulotomy (GVC) is an option to be considered for the treatment of refractory OCD patients. Clinical and neuropsychological studies with GVC in OCD patients have demonstrated the efficacy and safety oh this procedure efficacy and safety. However, personality studies with this treatment in OCD are not found in literature. The objective of this study was to investigate personality changes after one year of GVC in refractory OCD patients. Personality assessment was performed using the Revised NEO Personality Inventory (NEO PI-R) and the Cloninger\'s Temperament and Character Inventory (TCI) in fourteen refractory OCD patients before and one year after GVC. Personality data comparisons between treatment responders (n = 5) and non-responders (n = 9), and also linear regressions using a stepwise bidirectional elimination approach for variables selection were performed. As the main result, no impairment in personality was found after GVC. On the contrary, there was a decrease tendency in Neuroticism and Persistence scores and in general, patients\' data approached to controls\'. Patients responders presented a reduction in Neuroticism scores and an increase in Extraversion scores, whereas non-responders did not change personality. Persistence, Selfdirectedness and Cooperativeness were significant in predicting percentage of change in YBOCS scores. Novelty Seeking, Reward Dependence, Selfdirectedness and Cooperativeness were significant in predicting the percentage of improvement in global functioning. This improvement in global functioning after GVC could be thought of as relating to better motivation to begin tasks, pursue goals, complete tasks, and engage with others. In conclusion, GVC procedure for OCD treatment is not only safe in terms of personality changes, but it can also improve some of its dimensions

Full textBackground: lack of full extension of the knee is a disabling condition that sometimes needs to be treated invasively by a posterior capsulotomy of the knee, since conservative treatments have been exhaustively attempted. However, it is not clear if the procedure is able to improve anterior symptoms on the knee of patients with flexion contracture and if the full extension acquired can be kept throughout long-time follow-up. Methods: we conducted a retrospective cohort study of 21 patients diagnosed with minimal flexion contracture of the knee who underwent open posterior capsulotomy between 1990 and 2010. After 9.19 ± 6.68 years of follow-up, knee function and mean angle of fixed knee flexion were compared to baseline data and the recurrence rate was estimated. Complications investigated included knee instability and neurovascular damages. Results: all patients (100%) presented with a preoperative Lysholm score classified as poor or fair (mean, 58.66 ± 13.87, 95%CI 52.35–64.98), but 15 patients (72%) experienced an improvement to good or excellent scores (mean, 87.61 ± 8.81, 95%CI 83.60–91.63) after long-time follow-up. The mean preoperative angle of fixed flexion was 25.04 ± 9.15 degrees (95%CI 20.88–29.21) and it decreased to 4.28 ± 4.18 degrees (95CI% 2.38 – 6.19, after the follow-up. Conclusion: Based on these results, we conclude that posterior capsulotomy of the knee proved to be a safe and effective procedure to treat properly patients with painful knees secondary to lack of full extension with a low rate of recurrence even after a long-term follow-up.

Resumo: Realizou-se um estudo transversal com intervenção com os objetivos de identificar a influência da capsulotomia posterior unilateral com Neodímio: Ítrio-Alumínio-Granada (Nd:YAG) laser na função visual e em relação à percepção de dificuldades nas atividades diárias, e verificar a relação entre as medidas subjetivas e objetivas da função visual após a intervenção. A amostra, prontamente acessível, foi composta por 48 pacientes entre 40 e 80 anos, média de 68 anos, mediana de 70 anos, pseudofácicos uni ou bilaterais, com opacificação de cápsula posterior e acuidade visual menor ou igual a 0,30 (logMAR) em um olho, atendidos consecutivamente em um hospital universitário no Brasil. Todos os pacientes foram submetidos a capsulotomia posterior com Nd:YAG laser. Um questionário, elaborado a partir de estudo exploratório, foi aplicado antes e depois da intervenção. Após a capsulotomia posterior, a acuidade visual e a estereoacuidade melhoraram significativamente. Na percepção dos sujeitos, houve redução das dificuldades relacionadas às atividades diárias ligadas à visão, exceto passar roupas, tomar banho sem ajuda e pentear os cabelos. As medidas objetivas e a auto-avaliação da visão apresentaram congruência de resultados e todos os pacientes declararam ter valido a pena a realização do procedimento laser
Abstract: An interventional survey was conducted to assess the influence of Neodymium: Yttrium-Aluminium-Garnet (Nd: YAG) laser unilateral posterior capsulotomy on visual function and perception of difficulties with vision-related daily life activities, and to verify the association between objective and subjective measures of visual function after intervention. The readily accessible sample comprised 48 patients aged between 40 and 80 years, with uni- or bilateral pseudophakia, posterior capsule opacification and visual acuity equal to or less than 0,30 (logMAR) in one eye, consecutively seen at a Brazilian university hospital. All the patients were submitted to posterior capsulotomy by Nd:YAG laser. Before and after intervention, patients were asked to answer a questionnaire developed from data obtained in an exploratory study. After posterior capsulotomy, visual acuity and stereoacuity improved significantly. According to the subjects' perception, they found less difficulty in vision-related daily activities, except for ironing, bathing without help and combing the hair. Objective measures of visual function and self-rated visual function showed congruent results after intervention. All the subjects interviewed stated that the posterior capsulotomy procedure had been ¿worthwhile¿

Resumo: Este estudo foi realizado com o objetivo de desenvolver um modelo semiológico para determinar se a estereoacuidade medida pelo teste de Titmus pode ser um indicador objetivo de melhora funcional após a capsulotomia em casos unilaterais de opacificação de cápsula cristaliniana posterior. Catorze pacientes com opacificação de cápsula posterior unilateral pós-facectomia com implantação de lente intra-ocular (6 pacientes fácicos e 8 pseudofácicos no olho contralateral) foram estudados prospectivamente. A acuidade visual variou de 0,05 a 0,5 no olho com opacificação de cápsula posterior e de 0,7 a 1,0 no olho contralateral (sem opacificação de cápsula posterior). Todos os pacientes foram submetidos a capsulotomia posterior com Neodymium: Yttrium-Aluminum-Garnet (Nd:YAG) laser. A estereoacuidade pré e pós-capsulotomia foi medida pelo teste de Titmus. A análise estatística foi efetuada usandose testes não paramétricos (Wilcoxon e Spearman). Houve melhora significativa da estereoacuidade após a capsulotomia posterior com Nd:YAG laser nos pacientes da população estudada. O trabalho revelou dados preliminares para análise do efeito da capsulotomia posterior em casos de opacificação de cápsula unilateral na estereoacuidade, demonstrando que a catarata secundária reduz a visão estereoscópica e concluindo que a estereoacuidade, ao lado da acuidade visual, pode ser um parâmetro objetivo de indicação de capsulotomia em casos unilaterais de opacificação da cápsula posterior
Abstract: This study was designed to develop a semiologic model to determine whether stereoacuity is an objective mdicator of functional improvement following unilateral secondary capsulotomy. Fourteen patients with unilateral posterior capsule opacification post cataract surgery with implantation of intraocular lens (6 phakic, 8pseudophakic m contralateral eye) were studied prospectively. Visual acuity ranged from 0,05 to 0,5 m the eye with posterior capsule opacification and ranged from 0,7 to 1,0m contralateral eye. All patients had Neodymium: Yttrium-Alummum-Garnet (Nd:YAG) laser capsulotomy. Stereoacuity was measured before and afier capsulotmy by Titmus testo Nonparametric Spearman rank correlation and Wilcoxon rank tests were used for analysis. Stereoacuity improved afier capsulotomy m alI patients. The visual acuity m the eye with posterior capsule opacification did not correlate with stereoacuity afier capsulotomy. This study demonstrated that posterior capsule opacification reduces the depth vision and concluded that stereoacuity may provide an mdication for unilateral capsulotomy
