Word finding – Children with word finding difficulties may know a word, but have difficulty accessing it for production – similar to the tip of the tongue phenomenon. Pragmatics – Pragmatics refers to the ability to select the appropriate message, or interpret what others say, in relation to context. Pragmatic difficulties can give an impression of oddity, with the content of language not fitting the environmental or social context; comprehension may be over-literal; the child may chatter incessantly, be poor at turn-taking in conversation and maintaining a topic
Discourse – Discourse refers to a level of organization of language beyond the sentence. Child with limitations in this domain may have limited ability to tell a story or describe a set of events in a logical sequence
Verbal memory and learning – Problems with remembering words or sentences can affect both the learning of new vocabulary, and the understanding of long or complex sentences. Young children with DLD may say their first words later than other children. It may also take children with DLD longer to learn and remember novel words. Phonology – Phonology is the branch of linguistics concerned with the way sounds are combined in words. Children with difficulties with phonology may fail to distinguish between certain speech sounds, such as t and k, so that cake is produced as tate. Such difficulties are not unusual as part of typical development in toddlers, but they would usually resolve by the time children are 4–5 years old.
Histopathology
Tanapox virus in humans produces increased thickening of the epidermis with extensive degeneration of the prickle cell layer. The cytoplasm of the swollen epidermal cells is filled with large, pleomorphic, eosinophilic B-type inclusion bodies. Nuclei of infected cells are also swollen, with chromatin being concentrated at the nuclear periphery. Epidemiology
Human tanapox has been mostly documented in Kenya and Zaire, but it is believed to occur much more widely throughout tropical Africa. All age groups and both sexes appear to be affected by this virus. During the Kenyan epidemics of 1957 and 1962, cases of tanapox were reported more frequently among persons who worked or played close to the river. As a result of this, researchers concluded that tanapox is most likely a zoonosis. However, neither the reservoir host nor the mode of transmission from wild animal to human is known. It is hypothesized that tanapox virus may be transferred from monkeys or another reservoir host to humans by infected arthropods that act as mechanical vectors. Only one case of human to human transmission has been reported. References
