Lymphedema-distichiasis syndrome (LDS) is an autosomal dominant condition associated with FOXC2 mutations. Patients with distichiasis are mostly symptomatic, and efforts to deal with their ocular complaints comprise of electrolysis, cryotherapy and a variety of surgical techniques. We describe an enhanced surgical technique for a case of symptomatic distichiasis of the right eye with scarred, irregular eyelid margins secondary to initial cryotherapy, whereby the distorted tarsus was excised to remove the aberrant hair follicles, the levator palpebrae superioris was released to extend the upper lid and prevent lagophthalmos and a mucous membrane graft was used to cover the exposed portion of the tarsal plate...

BACKGROUND: Syphilitic uveitis is an infective uveitis and a great mimicker. Misdiagnosis can lead to delay in the specific treatment resulting in deterioration of uveitis and loss of vision. FINDINGS: A 38-year-old unmarried female presented with pain, redness, and blurring of vision in the left eye for the last 5 days. She denied history of any sexual exposure in the past. Anterior segment examination of the right eye was normal and the left eye showed keratic precipitates with anterior chamber cells and iris pigments on anterior lens capsule...

Bacillus cereus can cause endophthalmitis through secretion of virulence factors, including hemolysin BL (Hbl) and nonhemolytic entertoxin (Nhe). Carvacrol is an extract from oregano oil, with potential for curtailing B. cereus endophthalmitis, due to antimicrobial and anti-inflammatory qualities. However, sublethal levels of carvacrol increases B. cereus virulence. The goal of this study was to investigate the increase in B. cereus virulence potential in response stress induced by a subinhibitory concentration (SIC) of carvacrol...

Vitamin C is an organic compound that is almost ubiquitous in the daily diet of individuals. There are clear indications of supplementation when secondary deficiency is detected related with reduced dietary intake or reduced absorption. On the other hand, indications for supplementation concerning an increased need are controversial. Several authors have studied the role of vitamin C as an adjuvant in the treatment of diseases that may affect children and adolescents. These diseases affect all organs and systems: specifically, vitamin C supplementation could play a role in respiratory, neurological, psychiatric, oncohematological, nephrological, ophthalmological and nutritional disorders...

Pleural effusions may be related to pleuro-pulmonary or systemic disorders, including malignancy. Thoracentesis and thoracoscopy may be useful to diagnosis. In some cases, the diagnosis may be difficult and uncommon. We report the case of a hospitalized male for a pleuritis, with pleural effusion caused by a Bacillus megaterium infection, a Gram-positive, aerobic, spore-forming, and rod-shaped bacterium. To our knowledge, our case report is the first evidence of pleuritis due to B. megaterium. In the literature, up to now, B...

In recent years, group B streptococcus (GBS) has become an important pathogen that causes infections in many neonatal organs, including the brain, lung, and eye (Ballard et al., 2016). A series of studies performed on GBS infections in western countries have revealed that GBS is one of the primary pathogens implicated in perinatal infection, and GBS infections are a major cause of neonatal morbidity and mortality in the United States (Decheva et al., 2013). In China, GBS is mainly found by screens for adult urogenital tract and perinatal infections, and neonatal GBS infections have been rarely reported...

Treatment of infectious posterior uveitis represents a therapeutic challenge for ophthalmologists. The eye is a privileged site, maintained by blood ocular barriers, which limits penetration of systemic antimicrobials into the posterior segment. In addition, topical and subconjunctival therapies are incapable of producing sufficient drug concentrations, intraocularly. Posterior infectious uveitis can be caused by bacteria, virus, fungi, or protozoa. Mode of treatment varies greatly based on the infectious etiology...

Leishmaniasis is a neglected tropical disease caused by different species of protozoan parasites of the genus Leishmania. Dogs have been proven as primary hosts of the parasite. Cases of cutaneous leishmaniasis in humans caused by Leishmania mexicana have been reported in Sinaloa; however, the vectors and hosts involved in the epidemiology of the parasite in northwestern Mexico are still unknown. Given the public health implications of this parasite's domestic hosts regarding the permanence and transmission of the disease to humans, the objective of the present study was to detect and determine the species of Leishmania that caused the first three cases of autochthonous canine leishmaniasis in the state of Sinaloa, Mexico...

Toxoplasma is a common parasite worldwide that mainly affects the brain, lungs and eyes. Although toxoplasmic encephalitis is a lethal disease without treatment, past case reports show most patients with systemic lupus erythematosus who developed toxoplasmic encephalitis were misdiagnosed and treated as neuropsychiatric systemic lupus erythematosus, which led to unfavorable outcomes. We herein describe a case of disseminated toxoplasmosis affecting all the above organs with atypical symptoms, which developed with exacerbation of systemic lupus erythematosus...

Topical drugs containing chloramphenicol and clostridiopeptidase A are frequently used for the treatment of cutaneous ulcers and other necrotic lesions. Chloramphenicol is a bacteriostatic broad-spectrum antibiotic widely used in eye and skin ointments to treat bacterial infections and a well-known cause of allergic contact dermatitis (ACD) (1). Clostridiopeptidase A, also called collagenase 1, is a proteolytic enzyme facilitating the tissue granulation with consequent re-epithelization; it has rarely been reported as cause of ACD (2)...

Surfaces with regular contact with the human body are typically contaminated with microorganisms and might be considered as fomites. Despite spectacles being widespread across populations, little is known about their microbial contamination. Therefore, we swab-sampled 11 worn spectacles within a university setting as well as 10 worn spectacles in a nursing home setting. The microbial load was determined by aerobic cultivation. All spectacles were found to be contaminated with bacteria, with nose pads and ear clips having the highest density, i...

Dry eye is a multifactorial disease that is one of the most common diseases worldwide. A major cause of dry eye is the deficiency of aqueous tears, which are mainly secreted from the lacrimal gland. The lacrimal gland plays an important role in maintaining the health of the ocular surface and protecting it from environmental exposure. Dry eye can lead to ocular irritation and discomfort, as well as severe ocular surface diseases (e.g., ocular infections, corneal ulcerations, and ocular surface keratinization)...

Herpes simplex virus type-1 (HSV-1) is a significant pathogen that affects vision by targeting multiple regions in the human eye including iris. Using a focused library of synthetic non-saccharide glycosaminoglycan mimetics (NSGMs), we identified sulfated pentagalloylglucoside (SPGG) as a potent inhibitor of HSV-1 entry and cell-to-cell spread in the primary cultures of human iris stromal (HIS) cells isolated from eye donors. Using in vitro β-galactosidase reporter assay and plaque reduction assay, SPGG was found to inhibit HSV-1 entry in a dosage-dependent manner (IC50 ∼6...
