Sinonasal respiratory epithelial adenomatoid hamartoma: A report on three cases

2018

Respiratory Epithelial Adenomatoid Hamartoma (REAH) is a rare benign lesion that may occur in the nasal cavity and paranasal sinuses. Histology is essential for the differential diagnosis with other lesions that could affect the sinonasal region. Our report focuses on three cases of male patients that were 46, 66 and 73 years old, diagnosed with REAH of the sinonasal region. All cases presented a nasal obstruction and hyposmia, and in one case cephalalgia. The definitive diagnosis of REAH was supported by the endoscopic, radiological and histological examinations. The patients underwent surgical excision with an endoscopic approach and did not experience a local recurrence at the time of wr…

Association between maxillary sinus pathology and odontogenic lesions in patients evaluated by cone beam computed tomography. A systematic review and…

2019

Background A study is made of the association between maxillary sinus pathology and odontogenic lesions in patients evaluated with cone beam computed tomography. Material and Methods A literature search was made in five databases and OpenGrey. Methodological assessment was carried out using the Newcastle-Ottawa tool for observational studies. The random-effects model was used for the meta-analysis. Results Twenty-one studies were included in the qualitative review and 6 in the meta-analysis. Most presented moderate or low risk of bias. The periodontal disease showed to be associated with the thickening of the sinus membrane (TSM). Mucous retention cysts and opacities were reported in few st…

Respiratory epithelial adenomatoid hamartoma: An unusual case report

2020

Respiratory epithelial adenomatoid hamartoma is a rare lesion of the nasal cavity whose etiology and pathogenesis are unknown and symptoms are unspecific. It can be isolated or associated with inflammatory process, first of all nasal polyposis. It’s considered a rare lesion because it’s poorly known and consequently correctly diagnosing is important to a right surgical treatment and follow-up. A 54-year-old man presented with a 10-year history of epistaxis, rhinorrhea and anosmia. Computed tomography showed soft tissue densities in all sinus cavities consistent with nasal polyposis and without bilateral widening of the olfactory cleft >10 mm and without bone erosion. Functional endoscopi…

Effects of normobaric oxygen on ciliary beat frequency of human respiratory epithelium

1998

Respiratory infection is a major cause of morbidity after general anaesthesia. Impairment of respiratory ciliary beat frequency (CBF) by different stress factors causes a decrease in mucus transport rate (MTR). We have tested the effect of different concentrations of oxygen on CBF of human respiratory epithelium in a prospective, randomized, in vitro study. Samples of superficial mucosa of the inferior nasal turbinates of 20 non-smoking healthy volunteers were harvested and exposed to three different oxygen environments (group I = 21% oxygen, group II = 60% oxygen and group III = 95% oxygen) for 2 h. In 50% of the samples, exposure time was prolonged. At 30, 60, 90, 120 and 240 min, light m…

Myospherulose des Mittelohres - eine seltene Differenzialdiagnose des Cholesteatoms

2004

Background Myospherulosis is a chronic-inflammatory lesion that is most commonly iatrogenic of origin and occurs in tissues exposed to petrolatum-based products. The disease does not exhibit characteristic symptoms and is therefore not diagnosed in some instances. In previous otorhinolaryngological studies, myospherulosis was mainly found in paranasal sinuses, while only four otitic cases have been reported. Methods A 48-year-old female Egyptian patient suffered from bilateral chronic otitis media that had been treated in Egypt by tympanoplasty. The patient presented few months later at the university ENT department (Mainz) with deteriorated otorrhea and otalgia. Clinical, otoscopical, and …

Overweight/obesity and respiratory and allergic disease in children : international study of asthma and allergies in childhood (ISAAC) phase two

2014

Background: Childhood obesity and asthma are increasing worldwide. A possible link between the two conditions has been postulated. Methods: Cross-sectional studies of stratified random samples of 8-12-year-old children (n=10 652) (16 centres in affluent and 8 centres in non-affluent countries) used the standardized methodology of ISAAC Phase Two. Respiratory and allergic symptoms were ascertained by parental questionnaires. Tests for allergic disease were performed. Height and weight were measured, and overweight and obesity were defined according to international definitions. Prevalence rates and prevalence odds ratios were calculated. Results: Overweight (odds ratio=1.14, 95%-confidence i…

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…

Lower eyelid reconstruction by multiple subcutaneous pedicle flaps: a new method.

1992

Abstract In this paper we present an original technique for the reconstruction of the full thickness of the lower eyelid after excision of neoplasms. The method is based on the mobilisation of multiple pedicle subcutaneous flaps outlined in the same eyelid and supported by a chondro-mucosal graft. This technique is used for central and off-central losses which involve the outer rim or up to 75% of the width of the whole eyelid. This method is an alternative to the Hughes (1945), Mustarde´(1981), Tenzel and Stewart (1978) and McGregor (1973) techniques which we have previously used for this type of reconstructive The follow-up is satisfactory in terms of the oncological, functional and aesth…

Noninvasive respiratory support in the hypoxaemic peri-operative/periprocedural patient: A joint ESA/ESICM guideline.

2020

Hypoxaemia is a potential life-threatening yet common complication in the peri-operative and periprocedural patient (e.g. during an invasive procedure at risk of deterioration of gas exchange, such as bronchoscopy). The European Society of Anaesthesiology (ESA) and the European Society of Intensive Care Medicine (ESICM) developed guidelines for the use of noninvasive respiratory support techniques in the hypoxaemic patient in the peri-operative and periprocedural period. The panel outlined five clinical questions regarding treatment with noninvasive respiratory support techniques [conventional oxygen therapy (COT), high flow nasal cannula, noninvasive positive pressure ventilation (NIPPV) a…
