Foreign bodies in upper airway may have various presentations and be life threatening. Leeches can attach to upper airway and cause serious problems. Herein we report a 55-year-old man with hemoptysis due to attachment of leech and explain our technique for its removal.

Nasal mucosa has an extraordinary nerve supply with unique geometry that encompasses complex physiology. Among these, side-specific predilections to the respiratory and autonomic centers are the interesting issues that have been raised about the consequences of the nasal irritations. The aim of the study was an evaluation of how intranasal stimulation influences lung mechanics and determines wh...

mucormycosis is a serious fungal infection caused by the filamentous fungi of the mucorales order of the class of zygomycetes. mucormycosis is classically defined as an opportunistic fatal infection. in this report we explain a 49 years old woman with palato-orbital tract as a sequel of rhino cerebral mucormycosis and end stage renal disease candidate for kidney transplantation. difficulties in...

Birch and Tverberg partitions are closely related concepts from discrete geometry. We show two properties for the number of Birch partitions: Evenness, and a lower bound. This implies the first non-trivial lower bound for the number of Tverberg partitions that holds for arbitrary q, where q is the number of partition blocks. The proofs are based on direct arguments, and do not use the equivaria...

If a1, a2, . . . , ak and n are positive integers such that n = a1+a2+· · ·+ak, then the sum a1 + a2 + · · ·+ ak is said to be a partition of n of length k, and a1, a2, . . . , ak are said to be the parts of the partition. Two partitions that differ only in the order of their parts are considered to be the same partition. Let Pn be the set of partitions of n, and let Pn,k be the set of partitio...
