La obstrucción primaria adquirida infrasacal del ducto nasolagrimal es una entidad bastante frecuente en pacientes de edad media y avanzada que origina epífora blefaritis así como dacriocistitis crónica y/o recurrente.
 En el tratamiento esta patología se sigue considerando, aunque cada vez menos, la dacriocistorrinostomía (DCR) externa “el gold standard” con unas tasas éxito sitúan alrede...

Many advances in trauma care have resulted from the treatment of battle casualties by combat medics, military physicians and nurses. A recent example is damage control resuscitation (DCR), which is transforming the care of soldiers with haemorrhagic shock requiring damage control surgery (DCS) in the current conflicts in Iraq and Afghanistan. We believe that these new treatments have applicatio...

External dacryocystorhinostomy (DCR) is the gold standard surgical technique for the treatment of nasolacrimal duct obstruction (1). Since its introduction by Gibbs in 1967, intubation with silicone tubes has been widely used in lacrimal duct surgery (2). However, effect of silicone intubation on patency of lacrimal system during external DCR in cases of primary nasolacrimal duct obstruction (N...

1,3–Dipolar cycloaddition reactions (DCR) are atom–economic processes that permit the construction of heterocycles. Their enantioselective versions allow for the creation of up to four adjacent chiral centers in a concerted fashion. In particular, well–defined half–sandwich iridium (III) catalysts have been applied to the DCR between enals or methacrylonitrile with nitrones. Excellent yield and...

A 74-year-old male patient presented to the outpatient department with left-sided epiphora and chronic dacryocystitis, without any history of head trauma or previous nasal or paranasal sinuses surgery. No abnormalities were noted at the time with the use of nasal endoscopy. The computed tomography scan however revealed an osteoma of the medial wall of the left maxillary sinus. An endonasal endo...

PURPOSE To describe a modification of the retrograde intubation dacryocystorhinostomy (DCR) in patients with proximal canalicular obstruction. MATERIALS AND METHODS Interventional case report of a 43-year-old female with a nine-month history of left epiphora following a road traffic accident involving the proximal lower canaliculus. An external DCR approach was performed. Following the creati...
