Factors associated with patient visits to the emergency department for asthma therapy

BackgroundAcute asthma attacks remain a frequent cause of emergency department (ED) visits and hospital admission. Many factors encourage patients to seek asthma treatment at the emergency department. These factors may be related to the patient himself or to a health system that hinders asthma control. The aim of this study was to identify the main factors that lead to the frequent admission of asthmatic patients to the ED.MethodsA cross-sectional survey of all the patients who visited the emergency room with bronchial asthma attacks over a 9-month period was undertaken at two major academic hospitals. The following data were collected: demographic data, asthma control in the preceding month, where and by whom the patients were treated, whether the patient received education about asthma or its medication and the patients’ reasons for visiting the ED.ResultFour hundred fifty (N = 450) patients were recruited, 39.1% of whom were males with a mean age of 42.3 ± 16.7. The mean duration of asthma was 155.90 ± 127.13 weeks. Approximately half of the patients did not receive any information about bronchial asthma as a disease, and 40.7% did not receive any education regarding how to use asthma medication. Asthma was not controlled or partially controlled in the majority (97.7%) of the patients preceding the admission to ED. The majority of the patients visited the ED to receive a bronchodilator by nebuliser (86.7%) and to obtain oxygen (75.1%). Moreover, 20.9% of the patients believed that the ED managed them faster than the clinic, and 21.1% claimed that their symptoms were severe enough that they could not wait for a clinic visit. No education about asthma and uncontrolled asthma are the major factors leading to frequent ED visits (three or more visits/year), p-value = 0.0145 and p-value = 0.0003, respectively. Asthma control also exhibited a significant relationship with inhaled corticosteroid ICS use (p-value =0.0401) and education about asthma (p-value =0.0117).ConclusionThis study demonstrates that many avoidable risk factors lead to uncontrolled asthma and frequent ED visits.

Ocular manifestations in chronic granulomatous disease in Saudi Arabia

INTRODUCTION Chronic granulomatous disease (CGD) is a primary immunodeficiency disease caused by a genetic defect in the NADPH oxidase complex of phagocytic cells. Recent reports indicate that chorioretinal lesions are more common than previously suspected. In this study, ocular findings of CGD patients are described with particular emphasis on chorioretinal lesions as a potentially serious ocular complication of CGD. METHODS Medical records of CGD patients attending an immunodeficiency clinic at a tertiary care center from January 2004 to December 2006 were reviewed. Patients underwent full ophthalmologic examination. Patients with chorioretinal lesions were investigated for various causes of chorioretinitis. Molecular studies for common CGD-causing genes were performed in patients with chorioretinal lesions. RESULTS This cohort included 32 CGD patients: 14 (44%) had abnormal eye findings, 11 (34%) had anterior segment disease, and 4 (12.5%) had chorioretinal lesions. Posterior segment findings consisted of uniformly similar hypopigmented atrophic punched-out chorioretinal scars around the arcades and mid-equator sparing of the macula. One patient had exudative hemorrhagic total retinal detachment in the right eye. Two siblings with chorioretinal lesions had mutation in CYBB, an X-linked gene. Another patient carried a missense mutation in NCF2, causing autosomal-recessive disease. CONCLUSIONS While ocular manifestation is common in CGD, chorioretinal lesions seem less frequent. However, they present potential risk of visual loss; it is recommended that patients undergo regular ophthalmologic examinations. This report provides further evidence that chorioretinal lesions occur not only in X-linked, but they can also occur in the autosomal-recessive form of CGD.

Factors associated with poor asthma control in the outpatient clinic setting

BACKGROUND/OBJECTIVES: The goal of the study was to assess asthma control using asthma control test (ACT) and to explore the factors that effects asthma control among participants with bronchial asthma in the outpatient clinic setting. METHODS: This cross-sectional descriptive study was conducted in the outpatient primary care clinic at King Abdulaziz Medical City in Riyadh. Adult patients who were diagnosed with bronchial asthma by their primary treating physician were recruited over a 6-month period. Patients completed the ACT and questionnaires, which identified factors that affect asthma control. RESULTS: Four hundred asthmatic patients (n = 400) were enrolled, and 70% of these patients were women. Fifty-four percent of patients inappropriately used the inhaler device. The estimated prevalence of uncontrolled asthma at the time of the study was 39.8%. Inappropriate device use by the patient was more frequently associated with uncontrolled asthma (P—value = 0.001). Active smoking (P—value = 0.007), passive smoking (P—value = 0.019), unsealed mattress (P—value = 0.030), and workplace triggers (P—value = 0.036) were also associated with uncontrolled asthma. However, the extent of asthma control did not appear to be related to the existence of regular follow-ups, bedroom carpets, outpatient clinic visits, age, body mass index (BMI), or duration of asthma. CONCLUSIONS: The present study identified a high prevalence of uncontrolled asthma in the primary outpatient clinic setting and common risk factors that may contribute to poor asthma control.

Effect of age and gender in the prevalence of excessive daytime sleepiness among a sample of the Saudi population

The aim of this study is to assess whether the effect of gender on the excessive daytime sleepiness (EDS) is influenced by two confounders (age and hours of sleep per night). A cross-sectional study was conducted at King Abdulaziz Medical City-Riyadh (KAMC-R). A total of 2095 respondents answered a questionnaire that included questions regarding gender, age, hours of sleep per night, and daytime sleepiness using the Epworth Sleepiness Scale (ESS). The prevalence of EDS was 20.5% (females 22.2%, males 19.5%, p-value = 0.136). The EDS did not differ between genders, age groups, or hours of sleep per night (<6 vs. ⩾6 h). However, stratified statistical analysis shows that the prevalence of EDS did differ according to gender (25.3% in females, 19.0% in males, p-value = 0.036) in respondents with shorter hours of sleep per night. EDS was strongly related to female gender and young age (ages ⩽ 29 years) in respondents with short hours of sleep. This study reveals that one out of five of the general Saudi population has EDS. The effect of gender on EDS appeared to be influenced by hours of sleep per night. High EDS strongly related to female gender with short hours of sleep.

Tuberculous myocarditis is not always fatal: Report of three confirmed cases with uneventful outcome

Tuberculosis (TB) is a leading cause of death worldwide. It can affect any organ. However, cardiac involvement is extremely rare. Anti-TB therapy has been proved to be effective and curative in majority of TB cases except TB myocarditis, where it is found to be fatal. We describe three cases with confirmed TB with impaired left ventricular systolic function and low ejection fraction. All three cases improved clinically and left ventricular function returned to normal within a few weeks after the commencement of TB therapy.

Symptoms of Daytime Sleepiness and Sleep Apnea in Liver Cirrhosis Patients

BACKGROUND/PROPOSE Sleep disturbance and excessive daytime sleepiness (EDS) have been reported in patients with hepatic cirrhosis with no hepatic encephalopathy (HE). The objective of this study was to evaluate daytime sleepiness and risk of obstructive sleep apnea (OSA) among liver cirrhosis patients. MATERIAL AND METHODS A cross-sectional study was conducted at King Abdulaziz Medical City (KAMC)-Riyadh over a period of six months, using a structured questionnaire that investigated: 1) Sleep patterns and daytime sleepiness using the Epworth Sleeping Scale (ESS), and 2) The risk for sleep apnea using the Berlin Questionnaire (BQ). We enrolled patients with a confirmed diagnosis of liver cirrhosis who were being followed at the hepatology and preliver transplant clinics. RESULTS We enrolled 200 patients with liver cirrhosis, 57.5% of whom were male. The mean age was 60 (± SD 12.2). The reported prevalence of EDS, OSA, and both EDS and OSA were 29.5%, 42.9%, and 13.6%, respectively. The prevalence of EDS was higher in patients with Hepatitis-C and patients with DM, who experienced short sleep duration. We did not find any association between the severity of liver disease and EDS or OSA as measured by Child-Pugh scores (CPS). CONCLUSIONS The risk of OSA and EDS is high among liver cirrhosis patients. Those patients with cirrhosis secondary to Hepatitis C are at higher risk of EDS and OSA. Both EDS and OSA affect patients designated as CPS Class A more frequently than patients designated as CPS Class B.Background/propose.

Sugammadex versus two doses of neostigmine for reversal of rocuronium in gastric sleeve surgery

Background and Aim: The aim of this prospective randomized trial is to compare the quality of reversal of rocuronium with either sugammadex (SUG) versus 2.5 mg or 5 mg neostigmine (NEO). Patients and Methods: A total of 110 patients with body mass index >40 underwent elective gastric sleeve surgery were enrolled in this study. Exclusion criteria included patients with co-existing muscular and cardiovascular diseases. Patients were randomly allocated to one of the following groups: group A (SUG), Group B (NEO 2.5 mg), and Group C (NEO 5 mg). General anesthesia was induced in the three groups using propofol 2.0 mg/kg of corrected body weight (CBW) and fentanyl 3 mcg/kg of CBW. Anesthesia was maintained with O2/air/desflurane 1 minimum alveolar concentration. Remifentanil infusion started at 0.05–0.2 mcg/kg/min. Tracheal intubation was facilitated with rocuronium 1.2 mg/kg of CBW guided with PNS. When the train of four (TOF) reached zero, intubation was performed using a GlideScope. At the end of surgery, TOF ratio and posttetanic counts were recorded. SUG 2 mg/kg of CBW (Group A), NEO 2.5 mg (Group B), and NEO 5 mg (Group C) were administered according to the random envelope. The time to achieve 90% of TOF was recorded in seconds using a timer. ANOVA for repeated measurements was used for statistical analyses. P<0.05 was considered statistically significant. Results: There was a positive correlation (P < 0.05) between the duration of surgery and the time to reach 90% of TOF in all the three groups. The time to reach 90% TOF was significantly shorter with Group A versus Groups B and C (P < 0.05). Conclusion: Although SUG proved to be faster than NEO 5 mg in attaining TOF >90%, the recovery pattern of both was similar.
