Traumatic globe luxation: A case report

Globe luxation is a rare clinical event. Most of the cases are usually traumatic, although spontaneous globe luxation has also been reported. The majority of the posttraumatic cases are usually associated with the injury or fracture of the bony orbit. We report here a case of globe luxation that occurred per se without any injury to the orbital or maxillo-facial bony structures

CP-violation in a superstring inspired model with oxotic quarks

Exotic charge - &#x2153; colour triplet (h) quarks are contained in E<SUB>6</SUB> models. We examine the effects on CP violation resulting from h-b mixing and find that the lower bound on m<SUB>t</SUB> is removed, &#949;'/&#949; is reduced and B<SUP>o</SUP>-B&#x0305;<SUP>o</SUP> mixing remains unchanged

A case of <i>Goldenhar-Gorlin syndrome</i> with unusual association of hypoplastic thumb

A case of Goldenhar-Gorlin syndrome in a seven-month-old male infant presented with the features of epibulbar dermoid, microtia and hemifacial microsomia associated with thumb defect. The dermoid was bilateral and microtia was unilateral. Preauricular appendages and pits were double and single respectively on both the sides. Hemifacial microsomia was unilateral and was associated with cleft lip, macrostomia, dental misalignment, large tongue and high arched palate. The association of hypoplastic thumb with Goldenhar-Gorlin syndrome has not been documented in the past

D<SUP>0</SUP>-D̅<SUP>0</SUP> mixing in superstring-inspired E<SUB>6</SUB> models

In E6 models emerging at low energies from the superstring there are exotic charge-1/3 h-quarks. When h-b mixing is taken into account, SUSY contribution to D0-D̅0mixing is enhanced several orders beyond that in the standard model and is close to the experimental upper limit

A rare cause of nasolacrimal duct obstruction: Dentigerous cyst in the maxillary sinus

The most common abnormality of the lacrimal drainage system is congenital or acquired nasolacrimal duct obstruction. The causes of acquired nasolacrimal duct obstruction may be primary or secondary. The secondary acquired obstructions may result from infection, inflammation, neoplasm, trauma or mechanical causes. The maxillary sinus cysts usually obstruct the nasolacrimal duct mechanically. Dentigerous cysts are one of the main types of maxillary cysts. These cysts are benign odontogenic cysts which are associated with the crowns of unerupted teeth. The clinical documentations of mechanical nasolacrimal duct obstructions due to a dentigerous cyst in the maxillary sinus are very rare in literature. In this case report, we describe a dentigerous cyst with a supernumerary tooth in the maxillary sinus in an 11-year-old male child causing an obstruction to the nasolacrimal duct. The case was successfully managed surgically by Caldwell Luc approach

Ocular morbidity among children at a tertiary eye care hospital in Kolkata, West Bengal

Eye diseases in childhood are important causes of medical consultation and it affects learning ability, adjustment in school and personality. To determine the pattern of ocular morbidity a cross-sectional observational study was conducted among 714 children, attending Ophthalmology department at a tertiary eye care center in Kolkata, West Bengal. All the children less than 15 years of age, attending in Unit II outpatient department were selected by complete enumeration method for duration of one year (January-December 2010). Distribution of association was analyzed by Chi-square test and difference between two proportions was calculated by z test for proportions. The common ocular morbidity were refractive errors (23.67%) followed by allergic conjunctivitis (17.23%), infection of the eye and adnexa (15.13%), ocular trauma (12.74%), and congenital eye diseases (13.59%). Majority of ocular morbidity is treatable and need early attention through eye screening cum intervention program beginning right from the childhood
