Rhintis

BACKGROUND: Subcutaneous immunotherapy (SCIT) is the allergen-specific curative treatment of allergic rhinitis. Adverse effects, most of which are local, can be observed during the immunotherapy. These adverse effects have been reported more frequently during the pollen season. The purpose of this study was to estimate the rate of local, large local, and systemic reactions during the treatment, to determine the relationship between adverse reactions and the season in which these reactions occur, as well as the risk factors for adverse reactions during the grass pollen-specific SCIT treatment in children...

Spotaneous or non-traumatic cerebrospinal fluid rhinorrhea is an uncommon condition and may present a diagnostic challenge to clinicians. This condition is often being misdiagnosed for allergic rhintis or chronic sinusitis since the precipitating cause is not readily apperent in most patients. The mechanism of rhinorrhea is stil not completely clarified. We describe a case of this condition occuring in association with allergic rhinitis and sinusitis. A 52 year-old, obese female patient presented with two weeks history of bilateral clear nasal discharge and postural headache...

BACKGROUND: Studies have shown that pets are very important sensitizing agents in patients with asthma. Respiratory disorders such as asthma and allergic rhinitis are common in the State of Qatar. OBJECTIVE: The aim of the present study was to determine whether exposure to pets and domestic animals plays a significant role in the development of asthma and allergic rhinitis among Qatari population. DESIGN: A hospital-based prospective descriptive study conducted...

BACKGROUND: The systematic approach of the pediatric patient with recurrent upper airway obstruction (RUAO) must be based on a through clinical history, physical examination, and the adequate use of the laboratory and diagnostic procedures, which must complement the correct identification of the causes of UAO and its interrelation with comorbid conditions as allergic rhinitis, rhinosinusitis and adenoiditis, with or without significant hypertrophy. OBJECTIVE: this work, is to propose the study protocol of the patient with recurrent upper airway obstruction used in our own Instituto Privado de Alergia, Inmunología y Vías Respiratorias...

BACKGROUND: Very little information is available on the ultrastructure of the nasal cavity epithelium of the piglet. However, the nasal respiratory epithelium plays an important role in the pathology of atrophic rhintis of the piglet. Indeed, ciliated cells and mucus play a co-ordinate role in the colonization of the nasal cavity by the etiological agents of the disease. METHODS: In the present study, samples of the ventral nasal turbinates of germ-free piglets were processed for observation in the transmission electron microcope to describe the ultrastructure of their covering respiratory epithelium...
