The trail making test (TMT) is a short and convenient estimate of cognitive functions, principally attention and working memory. Like most neuropsychological tests, it is derived from and primarily applicable to English-speaking individuals. Norms for other ethnic minorities may differ significantly. The application of majority or mixed norms to specific ethnic subcultures may introduce systematic bias. To examine the impact of an English test on primarily nonEnglish-speaking individuals, outpatients attending the dermatology department of a large Indian hospital (n = 120) were asked to complete the English version of the TMT. The time taken to complete the TRAILS was unexpectedly long, although all the subjects scored within normal limits on the modified mini mental status examination and a test for general knowledge. Possible reasons for the delayed completion times are discussed below.
The imploding antrum or silent sinus syndrome is a rare phenomenon that presents with spontaneous painless enophthalmos and hypoglobus. It occurs due to ipsilateral maxillary antral atelectasis secondary to asymptomatic obstructive chronic sinus mucosal disease. Ophthalmologists, otorhinolaryngologists, and radiologists must be aware of this entity. This article illustrates the typical presentation in a 17-year-old male with unilateral ptosis and a deep superior sulcus, and characteristic imaging findings of ipsilateral increased orbital volume and depression of the orbital floor, maxillary sinus opacification and atelectasis with retraction of the posterolateral and medial walls, lateralization of the uncinate process, and obstruction of the ostiomeatal unit. This is probably the first time that the syndrome is being reported in such a young person. The pathogenesis, differential diagnosis, and treatment modalities of this entity are also reviewed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
