A 4-year-old girl was brought to a local emergency department (ED) after an episode of dizziness, vomiting, and horizontal nystagmus. Her parents reported that she was following them when they entered their garage to get a ball. When the girl did not appear in the garage, her parents went to look for her and found her lying next to a tree. When they attempted to get her to stand up, she complai...

In the present study the bones of the skull, excluding the hyoid apparatus, are described. All the bones are aerated by sinuses. In the occipital bone the squamous part is aerated from the sinus of the parietal bone, the lateral part is aerated from the tympanic bulla and the basal part from the sinus of the basisphenoid bone. Condylar foramens and hypoglossal canals are absent. A small interpa...

background: a known species lutztrema (lutziella) microacetabularae rhode, 1966 is being described for the first time from pakistan. this species is characterized by having body long and slender, oral sucker subterminal, acetabulum smaller than oral sucker lying in anterior third of the body, pharynx small, esophagus promi-nent which become gradually wider and bifurcates in to two rudimentary c...

The constrained Hamiltonian systems admitting no gauge conditions are considered. The methods to deal with such systems are discussed and developed. As a concrete application, the relationship between the Dirac and reduced phase space quantizations is investigated for spin models belonging to the class of systems under consideration. It is traced out that the two quantization methods may give s...

Results: Incidence of LF was 5.7 % (n:33). Isolated fistula of the lateral semicircular canal was found in 25 patients (75.7%), and isolated involvement of the oval window was found in one patient (3%). Multiple fistulas were detected in 7 patients (21.2%). In 31 patients (88.2%), the cholesteatoma was completely removed, and the fistula was sealed; and in 2 patients (5.8%) the matrix was left ...
