Etiología de baja visión y ceguera en siete centros de referencia en Colombia entre los años 2012 a 2017 / Etiology of low vision and blindness in seven reference centers in Colombia between the years 2012 to 2017

Introducción: La baja visión y la ceguera tienen alta prevalencia mundial, siendo categorías de discapacidad frecuentes en Colombia. Se requieren estudios que caractericen la etiología de las deficiencias visuales permanentes. Objetivo: Identificar y caracterizar las diferentes causas de baja visión y ceguera en siete centros de referencia para la población con discapacidad visual en Colombia, atendida entre los años 2012 a 2017 en seis ciudades capitales. Materiales y métodos:Estudio retrospectivo, serie de casos, descriptivo y multicéntrico.Resultados: Se contó con una muestra de 879 registros de pacientes con discapacidad visual. El 70% (612/879) con baja visión y 30% (267/879) con ceguera. Para todos los grupos de edad es más prevalente la baja visión. La etiología más frecuente en pacientes con baja visión fue la degeneración macular asociada a la edad (DMAE) (24%, 144/612); en pacientes con ceguera fue el glaucoma (17%, 45/267). Discusión: Posiblemente en Colombia las causas de baja visión y ceguera van más allá de las cataratas, errores de refracción no corregidos y ceguera infecciosa. Discusión: Las etiologías más frecuentes encontradas son condiciones oculares crónicas y diversas, que requieren intervenciones específicas para disminuir su prevalencia y prevenir casos de baja visión y ceguera.

Introduction: Low vision and blindness have high global prevalence, with categories of disability common in Colombia. Studies that characterize the etiology of permanent visual impairments are required. Objective:To identify and characterize the different causes of low vision and blindness in seven reference centers for the visually impaired population in Colombia, attended between 2012 and 2017 in six capital cities. Materials and Methods:Retrospective, case series, descriptive and multicenter study. Results: A sample of 879 records of visually impaired patients was available. Low vision is more prevalent for all age groups. 70% (612/879) low vision and 30% (267/879) blindness. The most common etiology in patients with low vision was age-related macular degeneration (DMAE) (24%, 144/612); in patients with blindness it was glaucoma (17%, 45/267). Discussions: Possibly in Colombia the causes of low vision and blindness go beyond cataracts, un corrected refractive errors and infectious blindness. Conclusions: The most common etiologies found are chronic and diverse eye conditions, which require specific interventions to decrease their prevalence and prevent cases of low vision and blindness.

TULUA: Effects of Flap Undermining and Type of Wall Plicature in a Rat Model Abdominoplasty.

BACKGROUND: TULUA, a transverse plication lipoabdominoplasty, which excludes elevation of the supraumbilical flap and includes a skin graft neoumbilicoplasty, claims greater safety and better results. An animal study was designed to compare it, with two current techniques. MATERIALS AND METHODS: Three matched groups of 12 rats had combined liposuction and abdominoplasty. Liposuction was extensive and unrestricted. Groups 1 and 2 had vertical plication and transposition umbilicoplasty, and group 3 had transverse plication and neoumbilicoplasty. Flap elevation in the epigastrium was wide to costal margins in group 1, limited to a tunnel in group 2, and no dissection in group 3. The animals were observed for 21 days and then euthanized. Intraoperative, postoperative, and postmortem variables and findings were measured and analyzed to find differences between groups. RESULTS: Transverse lipoabdominoplasty demonstrated a wider wall plication area, as well as a decrease in tension to close the wound, causing the horizontal scar to remain in a low position. In vertical plication lipoabdominoplasty groups, flap necrosis and seromas were more frequent, and the umbilical position descended due to secondary healing and scar contraction. The scar's scores were better in the transverse group and were confirmed when evaluated by external observers.In postmortem examination, horizontal plication presented less widening; perforator vessels were preserved when surgical undermining of the upper abdomen was not performed, and there were fewer seromas. CONCLUSION: In a rat model, TULUA demonstrates superior results and a decrease in complications when compared to lipoabdominoplasties with vertical plication and wide or tunneled dissection in the upper abdomen.

Embarazo posterior a lipoabdominoplastia de plicatura transversa, sin disección supraumbilical, liposucción irrestricta, neoumbilicoplastia y colocación baja de la cicatriz (TULUA): reporte de caso y revisión de la literatura / Pregnancy after transverse plication lipoabdominoplasty, undermining halted at umbilicus, liposuction without restrictions, umbilicoplasty with a skin graft, and low transverse scar localization (TULUA). Literature review and case report

RESUMEN Objetivo: Reportar el caso de una gestante con antecedente de abdominoplastia con plicatura transversa (transverse plication lipoabdominoplasty, undermining halted at umbilicus, liposuction without restrictions, umbilicoplasty with a skin graft, and low transverse scar localization - TULUA) y revisar la literatura disponible en torno al efecto queproduce la abdominoplastia sobre el embarazo y el impacto de la gestación sobre el resultado estético en una paciente con esta intervención. Materiales y métodos: Se reporta el caso de una mujer de 23 años, en estado de gestación, con antecedente de abdominoplastia ocho meses antes de su embarazo. Se realizó una búsqueda de la literatura en Medline vía PubMed, Cochrane library, SciELO, LILACS, BVS y Google Scholar, sin restricción por tipo de idioma o fecha de publicación. Se incluyeron estudios de cualquier diseño, incluyendo reporte de casos. Se excluyeron capítulos de libro y guías de práctica clínica. Resultados: La búsqueda identificó 1.158 estudios, de los cuales 13 cumplieron los criterios de inclusióny de exclusión, estos fueron series o reportes de caso, para un total de 111 pacientes. No se encontraron reportes de TULUA antes de embarazo. El rango de edad al momento del parto fue de 19 a 37 años y todos los neonatos fueron a término con peso adecuado para la edad gestacional. Once estudios describieron la vía de parto, siete por cesárea y cuatro por vía vaginal; dos estudios reportaron el desarrollo de prolapso cervical uterino, uno de ellos a las 15 semanas de gestación y otro al momento del trabajo de parto; tres pacientes experimentaron deficiente bloqueo nervioso en la pared abdominal durante la cesárea. En lo que respecta a los resultados estéticos después del parto, la literatura es limitada a la hora de describir una posible recidiva de laxitud cutánea o diástasis. No obstante, dos reportes de caso señalaron un resultado estético satisfactorio. Conclusión: la literatura sobre embarazo posterior a una abdominoplastia es escasa y se limita a reportes de caso. La abdominoplastia podría incrementar la frecuencia de prolapso cervical y de cesárea, sin que se conozca con precisión el impacto de la intervención sobre los resultados perinatales. La reparación de la pared abdominal aparentemente se mantiene. Se requieren más estudios que aborden el resultado perinatal en mujeres con abdominoplastia y el impacto de la gestación sobre los resultados de la intervención.

ABSTRACT Objective: To report the case of a pregnant woman with a history of transverse plication abdominoplasty (TULUA) and to conduct a review of the available literature on the impact of this intervention on the course of gestation and vice versa. Materials and methods: Case report of a 23-year-old pregnant woman with a history of TULUA abdominoplasty performed eight months before pregnancy. A literature search was conducted in Medline, Cochrane Library, SciELO, LILACS, BVS and Google Scholar, with no restriction by language or date of publication. Studies of any design were included, including case reports. Book chapters and clinical practice guidelines were excluded. Results: Overall, 1,158 studies were identified, of which 13 case reports or case series met the inclusion and exclusion criteria, for a total of 111 patients. No reports of TULUA before pregnancy were found. Age at the time of delivery ranged between 19 and 37 years and all births were at term, with newborns of adequate birth weight. Eleven studies described the route of delivery, including 7 cases of cesarean section and 4 vaginal deliveries. Two studies described the development of cervical prolapse, one at 15 weeks of gestation and the second at the time of labor. Three patients experienced impaired abdominal wall nerve block during the cesarean section. Regarding cosmetic results after delivery, there is a paucity of data about potential relapse in the form of skin laxity or diastasis. However, satisfactory cosmetic results were reported in two cases. Conclusion: There is a paucity of literature on the topic of pregnancy following abdominoplasty, and it is limited to case reports. The literature suggests that abdominoplasty could increase the frequency of cervical prolapse and cesarean section, although the impact on perinatal outcome is not clear. It appears that abdominal wall repair is maintained. Additional studies focusing on perinatal outcomes in women with abdominoplasty and the impact of gestation on the results of the intervention are required.

Tracoma: de lo básico a lo clínico / Trachoma: from basics to clinic / Tracoma: do básico ao clínico

RESUMEN El tracoma es una de las Enfermedades Tropicales Desatendidas; lo producen los serotipos A, B, Ba y C de la bacteria intracelular Chlamydia trachomatis, adquirida a partir de la diseminación directa por contacto ocular, propagación indirecta por fómites, transmisión por moscas que buscan los ojos y contacto con los dedos contaminados con secreciones oculares y nasales. En la actualidad es la principal causa de ceguera prevenible en el mundo, representa el 1,4 % de los casos totales y genera el deterioro visual de 1,8 millones de personas, de las cuales 500 000 tienen ceguera. Se calcula que hay 51 países endémicos distribuidos en África, Asia, Latinoamérica y Oceanía. En América hay focos activos en Brasil, México, Guatemala y Colombia. Las manifestaciones oculares iniciales son epífora, inyección conjuntival y secreción mucopurulenta; con el curso crónico se producen queratitis, entropión, triquiasis y opacidades corneales. El diagnóstico es básicamente clínico. Para eliminar esta enfermedad, la Organización Mundial de la Salud formuló el Programa Global para la Eliminación del Tracoma para 2020, basado en la implementación de la estrategia SAFE, consistente en cirugía para evitar complicaciones, tratamiento antibiótico, higiene facial y corporal y mejoramiento de las condiciones ambientales.

SUMMARY Trachoma is one of the Neglected Tropical Diseases. It is caused by the serotypes A, B, Ba and C o the intracellular bacteria Chlamydia trachomatis, acquired directly by ocular contact, and indirectly by fomites; also, transmitted by eye-seeking flies, and fingers contaminated with ocular and nasal secretions. Currently, trachoma is the leading cause of preventable blindness in the world, it represents 1.4 % of the total cases and generates visual deterioration in 1.8 million people, of which 500 000 are blind. It is estimated that 51 countries are endemic, distributed in Africa, Asia, Latin America and Oceania. Outbreaks in America take place in Brazil, Mexico, Guatemala, and Colombia. Initial ocular manifestations are epiphora, conjunctival injection and mucopurulent discharge; in the course of chronicity keratitis, entropion, trichiasis and corneal opacities are produced. Diagnosis is basically clinical. In order to eliminate this disease, the World Health Organization formulated the Global Program for the Elimination of Trachoma for 2020, based on the implementation of the SAFE strategy, which consists of surgery to avoid complications, antibiotic therapy, facial and body hygiene and the improvement of environmental conditions.
