Epistaxis and systemic disease
2008
Abstract We report the case of a 77-year-old man who presented nasal obstruction sensation and epistaxis. Otorhinolaryngologic examination revealed occupation of the left nasal passage and the left maxillary sinus by an inflammatory tumour, the biopsy results of which were inconclusive. While diagnostic tests were being carried out, the patient presented a severe systemic condition consisting mainly of anemia, acute renal failure, and cavitated diffuse bilateral lung infiltrates. In the light of the results of anti-neutrophilic cytoplasmic antibodies and renal biopsy, Wegener's granulomatosis was diagnosed and treatment for the disease was instituted, with a favourable response. Finally, cl…
It Takes a Mouth to Eat and a Nose to Breathe: Abnormal Oral Respiration Affects Neonates' Oral Competence and Systemic Adaptation.
2012
Review Article; International audience; Mammalian, including human, neonates are considered to be obligate nose breathers. When constrained to breathe through their mouth in response to obstructed or closed nasal passages, the effects are pervasive and profound, and sometimes last into adulthood. The present paper briefly surveys neonates' and infants' responses to this atypical mobilisation of the mouth for breathing and focuses on comparisons between human newborns and infants and the neonatal rat model. We present the effects of forced oral breathing on neonatal rats induced by experimental nasal obstruction. We assessed the multilevel consequences on physiological, structural, and behav…
