Localization of the atrial natriuretic factor in the human inferior turbinates. An immunohistochemical study

In man, the architecture of the turbinates is able to modify some of the physiochemical characteristics of the air inhaled. These modifications depend on the nervous system and on the action of neurotransmitters such as vasoactive intestinal peptide. Substance P, calcitonin gene-related peptide and other neuropeptides. As atrial natriuretic factor has been detected in the trachea and lung, the present immunohistochemical study was carried out to establish the presence and localisation of the atrial natriuretic factor on the inferior turbinates of the human being. The findings show atrial natriuretic factor to be present in the serous epithelial cells and in some cells of the tonaca propria …

Emotimpano e timpano da stasi quadri otoscopici e reperti audiometrici

Emotimpano e timpano da stasi: quadri otoscopicie reperti audiometrici. Gli Autori inquadrano sotto le denominazioni di «emotimpano» e «timpano da stasi» queei casi in cui la membrana timpanica appare di colore blu, ardesia o aceinio. Dopo aver brevemente preso in considerazione le diverse etiopatogenesi, gli Autori illustrano i reeparti audiometrici riscontrati nei casi da loro osservati, studiando le correlazioni fra deficit funzionale e qudro otoscopico.

Bilateral hairy polyp of the oropharynx.

AbstractHairy polyp of the nasopharynx is an unusual but well-recognized entity, generally presenting as a single mass at birth or in the first year of life. We describe the clinico-pathological features of a previously unreported bilateral hairy polyp in an adult and briefly discuss the pathogenesis of this condition.

Uncommon site of Neurofibromatosis type 1 (NF1) involving the external auditory canal (EAC). Case Report

Purpose: Evaluation and discussion of the procedure of the gufoni manoeuvre and its advantages in the treatment of BPPV of LSC Matherial and methods:Prospective study of 58 patients affected by LSC BPPV who where office-treated with Gufoni manoeuvre Results:Seventy-nine percent of ptients so treated had complete resolution of symptons, and 6,9% did not show any improvement in their symptons.The remaining 13,8% had a conversion into posterior semicircular BPPV Conclusions:Gufoni''s manoeuvre is effective in treating patients suffering from BPPV of LSC;it is simple to perform;there are not many movement to execute, it needs low time of positioning, and positionsare confortable to the patient …
