Objectives: The management of asthma by specialists is likely to become more evidence-based. This study analysed the characteristics of patients reporting to a specialist clinic including demographics, dispensed medications and the level of asthma control.

Methods: All consecutive stable asthmatics seen in the adult pulmonary clinics of Sultan Qaboos University Hospital, Oman, between December 2005 and November 2006 were prospectively evaluated using a structured assessment protocol.

Background: Incense burning has been reported to adversely affect respiratory health. The aim of this study was to explore whether exposure to bakhour contributes to the prevalence of asthma and/or triggers its symptoms in Omani children by comparing two Omani regions with different prevalence of asthma.

Methods: A randomly selected sample of 10 years old schoolchildren were surveyed using an Arabic version of ISAAC Phase II questionnaires with the addition of questions concerning the use and effect of Arabian incense on asthma symptoms.

International guidelines recommend the use of population-specific reference values to eliminate the well-recognized influence of ethnic variation on lung function. This study was designed to derive spirometric prediction equations for healthy Omani adults. Forced vital capacity (FVC), forced expiratory volume in one second (FEV(1)), peak expiratory flow rate (PEFR), and forced expiratory flow at 25% to 75% of FVC (FEF(25-75%)) were measured in 419 "healthy" nonsmoking Omani adults (256 men, 163 women), aged 18-65 years.

Objective: To audit the sleep service at Sultan Qaboos University Hospital (SQUH), Muscat, Oman, and to explore deficiencies to introduce new measures of improvement.

Methods: Polysomnography (PSG) reports and SQUH medical records of all patients who underwent sleep studies from January 1995 to December 2006 in the sleep laboratory at SQUH were reviewed and analyzed.

Results: Out of a total of 1042 sleep studies conducted in the specified period, 768 PSG recordings were valid for analysis.

Objective: Identification of relevant allergens that are prevalent in each environment which may have diagnostic and therapeutic implications in allergic diseases. This study aimed to identify the pattern of sensitisation to inhalant allergens in Omani patients with asthma, allergic rhinitis and rhinoconjunctivitis.

Methods: The study was carried out during three consecutive years (2004-2006) at the allergy skin test laboratory of Sultan Qaboos University Hospital, Oman.

Objectives: The International Study of Asthma and Allergies in Children (ISAAC) highlighted the presence of wide variations in asthma prevalence between and within countries. The aim of this study was to determine the changes in the prevalence of asthma and its symptoms across the different regions of Oman.

Methods: Two cross-sectional surveys were conducted as part of ISAAC phases I (1995) and III (2001) in two age groups (6-7 and 13-14 years) from nation-wide samples of Omani school children, with 7,067 participants in 1995 (3,893 young and 3,174 older group) and 7,879 participants in 2001 (4,126 young and 3,753 older group).

Background And Objective: This study evaluated changes in the prevalence of asthma symptoms and asthma severity in Omani school children over time.

Methods: Two cross-sectional surveys, in 1995 and 2001, were conducted as part of the International Study of Asthma and Allergies in Children on Omani schoolchildren in two different age groups (6-7 and 13-14 years).

Results: There were 7067 children surveyed in 1995 (3893 in the younger and 3174 in the older group) and 7879 in 2001 (4126 in the younger and 3753 in the older group).

Background: Studies continue to show poor physician compliance with asthma management guidelines in clinical practice. However, standardized protocols specifically designed to be practical and user-friendly improve patient outcomes.

Objective: To determine the degree of physicians' compliance with the documentation of an asthma management protocol in a university hospital.

Objectives: Normal lung function has been shown to be population specific. The aim of this study was to derive normal reference spirometric values for Omani children and adolescents.

Methodology: Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV(1)), peak expiratory flow and forced mid-expiratory flow were measured in 837 healthy Omani school children aged 6-19 years.

Objectives: Although asthma, allergic rhinitis and eczema are among the most common chronic diseases in children worldwide, there is very limited information about the burden of these conditions in Oman. The aim of this study was to determine the prevalence and severity of symptoms of asthma, allergic rhinitis and eczema in Omani schoolchildren using the International Study of Asthma and Allergies in Childhood (ISAAC) Phase I questionnaire.

Methods: An Arabic version of the ISAAC Phase I questionnaire was completed by parents of 3893 children aged 6-7 years and self-completed by 3174 children aged 13-14 years, randomly selected from a nationwide sample of public schools.

Objectives: To determine the range of serum IgE in healthy subjects and in asthmatic patients in Oman and to assess the degree of atopy in the asthmatic patients.

Method: Serum IgE and in vivo (the skin prick test) and in vitro (the ImmunoCAP test) allergen-specific IgE levels were measured in 44 patients with asthma. Control groups were 19 healthy subjects and 27 asymptomatic allergic subjects.
