Oral mucosal lesions in a Chilean elderly population: A retrospective study with a systematic review from thirteen countries.
2016
Background The oral examination is an essential part of the multidisciplinary medical care in elderly people. Oral mucosal lesions and normal variations of oral anatomy (OMLs) are very common in this people, but few studies have examined the frequency and prevalence of these conditions worldwide and less in Chile. The aim of this research was to evaluate the frequency of OMLs in a Chilean elderly population. Material and methods It was conducted a retrospective study (Talca, Chile). Two hundred seventy-seven OMLs were classified in groups and anatomical sites. In order to contextualize our numbers, we made a systematic review using Publish or Perish software, Google Scholar and InteractiVen…

An innervated retroauricular skin flap for total earlobule reconstruction.
2003
In this article, the authors describe a technique for total earlobule reconstruction in a patient who underwent earlobule excision for basal cell carcinoma. The reconstruction was by means of an innervated retroauricular skin flap, folded double. The flap presented preserved skin sensitivity over all the reconstructed area, which is compromised by those techniques using a cranially or medially based flap which lead to the reconstruction of an insensible earlobule. This is a very important aspect of this technique, especially for those who wear pendant earrings, since a non-sensitive lobule would be more vulnerable to traumas causing laceration. In addition, it allows a good aesthetic result…
Laserfotokoagulation und photodynamische Therapie (PDT) zur Behandlung der retinalen angiomatösen Proliferation (RAP) bei feuchter altersabhängiger M…
2008
BACKGROUND: Retinal angiomatous proliferation (RAP) is a subtype of neovascular age-related macular degeneration (AMD) with particularly bad prognosis. Diverse treatment modalities are performed. PATIENTS AND METHODS: This is a retrospective review on the treatment results of 41 consecutive patients from 1 / 2003 to 12 / 2005 with RAP stage 1 - 3 (Yannuzzi classification), who were treated with laser photocoagulation, photodynamic therapy (PDT) and intravitreal injection of triamcinolone acetonide (IVT). Follow-up was 12 months minimally. RESULTS: In RAP stage I complete closure of the vascular lesion in 14 / 22 eyes was achieved by 1.2 ± 0.5 sessions of laser photocoagulation (4 × combined…

High-resolution images in macular disorders
2021
Objective: This study analyzed and compared the results of adaptive optics (AO) and fundus autofluorescence (FAF) in various maculopathies. Methods: The study included four different types of maculopathy: central serous chorioretinopathy (CSC), retinitis pigmentosa (RP), Stargardt disease (STGD) and phototoxic retinopathy. In all four cases, cone mosaic and cone density were obtained using AO fundus camera. Further, the high-resolution images were compared with the FAF and optical coherence tomography (OCT) results. Results: In CSC, FAF and AO, changes could be shown in the macula even two years after the subretinal fluid resorption, as opposed to a normal OCT. The improvement of FAF and co…
Komplikationen einer großen kongenitalen Ziliarkörperzyste
2002
Background Multiple cysts of iris and ciliary body may cause many complications such as acute or chronic angle closure glaucoma. Patient We present a boy with multiple congenital cysts of the iris pigment epithelium and a voluminous cyst of the unpigmented ciliary body epithelium of the right eye. This resulted in lenticular astigmatism, concomitant strabismus divergens and subsequently to anisometropia. The voluminous cyst (8 x 12 mm in diameter) was folded around the lens, reached the optic axis and resulted in displacement of the lens and contact between the iris and the corneal endothelium from 6.30 to 11. After puncture and partial resection of the cyst at the age of 8 months the boy d…
