Functional and molecular 3D mapping of angiosarcoma tumor using non-invasive laser speckle, hyperspectral, and photoacoustic imaging.

Purpose: The gold standard for skin cancer diagnosis is surgical excisional biopsy and histopathological examination. Several non-invasive diagnostic techniques exist, although they have not yet translated into clinical use. This is a proof-of-concept study to assess the possibility of imaging an angiosarcoma in the periocular area.

Outcomes of external and endonasal dacryocystorhinostomy according to a modified Lacrimal Symptom Questionnaire (Lac-Q).

Background: Nasolacrimal duct obstruction is usually treated using endoscopic or external dacryocystorhinostomy (DCR). The anatomic outcomes of both the endoscopic and external approaches are considered excellent. However, anatomic success does not translate into patient satisfaction.

Is a bacterial biofilm in the lacrimal sac the cause of chronic refractory dacryocystitis? - A pilot study.

Purpose: A pilot study to identify bacterial biofilm in the lacrimal sacs of patients with chronic dacryocystitis, and in patients with epiphora but without discharge, using scanning electron microscopy.

Methods: Five patients: two with nasolacrimal duct obstruction without dacryocystitis, and three with dacryocystitis refractory to antibiotics, underwent external dacryocystorhinostomy. One control patient without infection was included.

First-Onset Dacryocystitis: Characterization, Treatment, and Prognosis.

Introduction: To assess the risk of recurrent dacryocystitis after first-onset dacryocystitis and to obtain a demographic profile and treatment characteristic for patients with first-onset dacryocystitis.

Methods: A retrospective study was performed on patients who had first-onset dacryocystitis during the years 2010-2013. Patients were followed up for 3 years.
