PURPOSE: Enterococcus faecalis causes severe acute endophthalmitis and often leads to poor visual outcomes. Conjunctival bacterial cultures occasionally grow atypical bacteria including E. faecalis, which can potentially contribute to the development of postoperative endophthalmitis. However, the characteristics of these ocular E. faecalis strains are unknown. This study is the first attempt to determine the population characteristics of E. faecalis clinical isolates from eye infections and ocular commensals...

Herpes simplex virus type 1 (HSV) keratitis is a leading cause of infectious blindness. Clinical disease occurs variably throughout the cornea from epithelium to endothelium and recurrent HSV stromal keratitis is associated with corneal scarring and neovascularization. HSV keratitis can be associated with ocular pain and subsequent neutrophic keratopathy. Host cell interactions with HSV trigger an inflammatory cascade responsible not only for clearance of virus but also for progressive corneal opacification due to inflammatory cell infiltrate, angiogenesis, and corneal nerve loss...

Small amoebae belonging to the Acanthamoeba genus complete their life cycles in different environmental niches as free-living protists however some of them are facultative parasites that can cause severe disease in humans. The sight-threatening Acanthamoeba keratitis develops in immune-competent persons, mainly in contact lens wearers; it is detected with increasing frequency along with the spread of contact lens use. The high abundance of the amoebae in the environment is important for dispersion and transmission of the infections among humans...

The incidence of sparganosis, a parasitic disease caused by plerocercoid larvae of the genus Spirometra, has gradually risen worldwide (especially in remote areas) in recent years. Pulmonary and pleural sparganosis, as well as other sites of infestation, including the subcutaneous tissues, the abdominal viscera, brain and eyes, has been reported. In clinical practice, due to the atypical signs and symptoms and limited laboratory approaches for the specific detection of sparganum, sparganosis is often misdiagnosed...

A 40-year-old man had uneventful small-incision lenticule extraction. Three days later, the uncorrected distance visual acuity was 20/20 and the cornea was clear without intraocular inflammatory in both eyes. At 6 days, the patient presented with a foreign-body sensation in the right eye but with no decrease in vision. Dense infiltration was visible at the inferior nasal corneal rim on slitlamp microscopy. Anterior segment optical coherence tomography showed the lesion in the junction of the capsular bag and the lenticular edge...

Acute bacterial sinusitis (ABS) mostly occurs as a complication of acute viral upper respiratory tract infection (URI), which is a common condition encountered in an outpatient setting. ABS manifests with three different presentations, most commonly as persistent symptoms of viral URI (nasal drainage and or cough) for more than 10 days. ABS is also diagnosed when the patient presents with severe symptoms of a URI accompanied by fever >102.2°F and purulent nasal drainage for at least 3 days. Lastly, ABS can complicate viral URI around day 6 or 7 of illness after initial improvement in the symptoms of URI...

A 19-year-old Nepalese male presented with complaints of bilateral ocular discomfort, photophobia, watering, and redness for 1 week. Visual acuity was 6/12 and 6/60 in the right and left eye, respectively. On biomicroscopic examination, presence of peripheral stromal infiltrates with conjunctival follicles was noted; infiltrates progressed to involve central cornea with further decrease in vision over next few days. After ruling out infectious keratitis, detailed systemic examination and laboratory investigations were diagnostic of neuro-Behçet's disease...

Nocardia is a ubiquitous environmental pathogen that causes infection primarily following inhalation into the lungs. It is generally thought to cause infection primarily in immunocompromised patients, but nonimmunocompromised individuals are also at risk of infection. We sought to compare risk factors, clinical manifestations, diagnostic approach, treatment, and mortality in immunocompromised and nonimmunocompromised adults with nocardiosis.We studied all adults with culture-proven Nocardia infection at a tertiary care hospital from 1994 to 2015 and compared immunocompromised with nonimmunocompromised patients...

BACKGROUND: Sore throat is common after tracheal intubation. Water can be used to lubricate tracheal tubes, but its benefit has not been validated. We thus did a randomised non-inferiority trial to test the hypothesis that a tube lubricated with water does not reduce sore throat after tracheal intubation. METHODS: We randomized female or male patients (n = 296) undergoing surgery in the ears or eyes to receive either a tube lubricated with water or a tube without lubrication for intubation...
