Airways Hyperresponsiveness

OBJECTIVE: To compare the prevalence ol exercise induced bronchial hyperresponsiveness in Inuit children with that or children in Montreal, and to identify possible genetic and environmental determinants of the differences observed.DESIGN: Cross-sectional survey.SETTING: Salluit, an isolated Inuit community in northern Quebec, and Montreal.POPULATION STUDIED: All children attending school in Salluit in grades 2 to 6 were eligible to participate. For the Montreal study, 18 schools were selected and from each of these one class from each of grades 1, 3 and 5 were chosen.MEASUREMENTS: Data collection for both locations included an exercise challenge test to assess exercise induced bronchial hyperresponsiveness (EIBH), allergy skin testing, a questionnaire for parents regarding details or the home environment as well as the child’s history of respiratory symptoms, and collection of dust samples from the bedroom floor and mattress for the presence of house dust mite.RESULTS: The prevalence or EIBH (defincd as a decline of 15% or more between pre-exercise forced expiratory volume in 1 s [FEV1] and that at 5 or 10 mins postexercise) was 19.5% (23 of 118) among the Inuit children, compared with 8.8% (87 of 989) among the Montreal children. In contrast. only 8.6% of the Inuit children had a positive allergy skin test compared with 34% in Montreal.CONCLUSIONS: A higher prevalence of EIBH was found in Inuit schoolchildren compared with children of similar age in Montreal, although the prevalence of atopy was considerably lower.

Exercise Induced

INTRODUCTION: Exercise induced bronchoconstriction (EIB) is transient narrowing of lower respiratory tract airways after exercise. It affects about 5 to 20 % of healthy individuals and 80% of Asthmatics. Obesity has been considered as one of the risk factor to the development of EIB. Symptoms of EIB are nonspecific and can be seen in a variety of disorders and studies have shown a lack of diagnosis specificity and sensitivity based on symptoms. AIM: The aim of this study was to evaluate frequency of EIB in Medical students of Govt. Medical College Miraj. We also tried to find out association of body mass index (BMI) with EIB. We also tried to find out correlation of subjective feeling of breathlessness (symptom of EIB) with actual findings of spirometry tests used to asses EIB. METHOD: This cross-sectional observational study was conducted on 80 male medical students. Exercise challenge test was conducted for participants. Pre and post-test values of Forced expiratory volume in one second (FEV1) and Peak expiratory flow rate (PEFR) were compared and students with ≥ 10% decrease in post-test FEV1 & PEFR were considered positive cases of exercise induced bronchoconstriction. Statistical analysis was done by using software, IBM-SPSS VER 20. RESULT:In our study frequency of EIB in medical students was 6.4%. Decrease in post-test FEV1 and PEFR values were statistically significant with Pvalue < 0.001. Our findings show that there was no association between BMI and EIB. Our study results also reveal strong correlation between subjective feeling of breathlessness measured in terms of visual analogue scale (VAS) and objective spirometry tests used to assess EIB. CONCLUSION: EIB is one of the major problems to be addressed as increasing frequency of EIB in healthy population could pose a threat when people attempt exercise training for their health benefits. Proper care with physician's consultation can minimize undue risks associated with EIB in healthy people.

Insight Into

OBJECTIVE: To report the occurrence of acute bronchospasm in one asthmatic patient and increased bronchial reactivity in another following the administration of a single dose of oral baclofen. CASE SUMMARY: On two separate occasions, a 46-year-old asymptomatic asthmatic man developed dyspnea and chest tightness one hour after the ingestion of baclofen 40 mg. Pulmonary function studies revealed a significant decrease in airflow relative to baseline. A 33-year-old asymptomatic woman with a history of exercise-induced dyspnea and wheezing displayed bronchial hyperresponsiveness to inhaled methacholine 2 hours after ingesting 40 mg of baclofen. The patient had had a negative methacholine challenge test 72 hours earlier. DISCUSSION: The gamma-aminobutyric acid-agonist baclofen has been shown to reduce airway responsiveness to various bronchoconstricting agents in animal studies. The etiology of this seemingly paradoxical response in two patients is unclear, but may offer insight into the neurally mediated airway constriction that occurs in asthma. CONCLUSIONS: Clinicians should be aware of the possibility of baclofen-induced bronchospasm, especially in asthmatic patients.

BackgroundCellulitis is a common painful infection of the skin and underlying tissues that recurs in approximately a third of cases. Patients’ ability to recover from cellulitis or prevent recurrence is likely to be influenced by their understanding of the condition.AimTo explore patients’ perceptions of cellulitis and their information needs.MethodMixed methods study comprising semi-structured, face-to-face interviews and cross-sectional survey, recruiting through primary care, secondary care and advertising. Adults aged 18 or over with a history of cellulitis (first or recurrent) were invited to complete a survey, take part in an interview or both. Qualitative data was analysed thematically.ResultsThirty interviews were conducted between August 2016 and July 2017. Qualitative data revealed low prior awareness of cellulitis, uncertainty around diagnosis, concern/surprise at the severity of cellulitis, and perceived insufficient information provision. People were surprised they had never heard of the condition and that they had not received advice or leaflets giving self-care information. Some sought information from the internet and found this bewildering. Two hundred and forty surveys were completed (response rate 17%). These showed that, while most people received information on the treatment of cellulitis (60.0%, n = 144), they reported receiving no information about causes (60.8%, n = 146) or prevention of recurrence (73.3%, n = 176).ConclusionThere is a need for provision of basic information for people with cellulitis, particularly being informed of the name of their condition, how to manage acute episodes, and how to reduce risk of recurrence.

UNSTRUCTURED E-health system is emerging and providing health services and solutions through different electronic gadgets. Saudi Arabia has launched a program called Saudi Arabia vision 2030, in which providing state-of-the-art health facilities to their citizen is of topmost priority. After all the efforts, the residents of Saudi Arabia are still reluctant for the adaptation of e-health system. The current study was conducted to evaluate the obstacle in adoption of the e-health system through the mobile phones. The current study was cross-sectional survey and was conducted by developing a self-administered structured questionnaire asking the utilization of mobile phone in state of health emergency prior to ask any medical history. Majority of the participants was married and doing jobs in different firms and have their personal mobile phones (p = 0.100, > 0.05) which indicates easily access to the e-health apps. The majority of the participants suffers from either obesity or high blood pressure (p = 0.018, < 0.05) regardless of either history of mental disorder or other family history of mental diseases. The pattern of diseases with mental disorders correlate well with adoption of e-health in government policies. The obstacles in adopting e-health includes fear of the loss of personal data and information (p = 0.0401, < 0.05). Moreover, they did not trust on online medications as the doctor cannot prescribe medicines without seeing physical health of the patient. The current study concluded that by making improvement in policies and proper commercializing the e-health apps together with awareness programs can boast the adoption of e-health in Saudi Arabia.

Concussion Education

Objectives There are two objectives for this paper. First, to determine effects of a concussion education program in a local school board in terms of concussion-specific knowledge in children and confidence in identifying and managing concussion in adults. Second, to identify differences and similarities in concussion knowledge between children who participate in sports and those who do not and between children with a history of one or more concussions and those without. Design A cross sectional survey regarding concussion knowledge was distributed randomly to students and adults at both pre- and posteducation timepoints. A concussion education program was disseminated across the school board for students between the distribution survey timepoints. Following the education program, adults and students completed their respective post-test surveys. Chi-squared tests in SPSS determined the significance of between-group differences. Results All 17 adults (100.0%) who had received concussion education recently reported confidence in their knowledge of concussion management, compared to 35.7% adults who had not received education for over a year (p = 0.020). For students, all of whom completed the concussion education training between the pre- and post-tests, there were no significant differences in concussion knowledge scores between athletes and non-athletes (either in or outside of school) or between those with a history of concussion and those without. There were no significant changes in concussion knowledge between the pre- and post-tests, except for one question. Conclusion Concussion education programs increase confidence of concussion management protocols in adults involved in sport, but they require improvements to better support knowledge amelioration, particularly for target groups that are at high risk of sustaining another injury.

Objectives: To investigate the frequency, characteristics and impact of death threats by patients towards psychiatrists. Methods: A cross-sectional survey of psychiatrists (n = 60) was undertaken to investigate the frequency, characteristics and impact of death threats by patients in one Irish healthcare region serving a mixed urban–rural population of 470,000. Results: Forty-nine responses (82%) were received. Thirty-one per cent of respondents experienced death threats by patients during their careers. Victims were more likely to be male and in a consultant role. Patients making the threats were more likely to be males aged 30–60 with a history of violence and diagnosis of personality disorder and/or substance misuse. A majority of threats occurred in outpatient settings and identified a specific method of killing, usually by stabbing. Prosecution of the perpetrator was uncommon. Of the victimised psychiatrists, 53% reported that such threats affected their personal lives, and 67% believed their professional lives were impacted. In half of the incidents, there were adverse incidents subsequent to the threats, involving either the patient or the clinician. Conclusions: Death threats by patients have significant psychological and professional impacts on psychiatrists. Early liaison with employers and police and transferring the care of the patient to another clinician may be useful measures.

Abstract Background There are no pharmacological interventions currently available to prevent the transmission of SARS-CoV-2 or to treat COVID-19. The development of vaccines against COVID-19 is essential to contain the pandemic. we conducted a cross-sectional survey of Shanghai residents to understand residents’ willingness to be vaccinated with any future COVID-19 vaccines and take measures to further improve vaccination coverage. Methods We conducted a cross-sectional survey using self-administered anonymous questionnaires from 1 July to 8 September 2020. The main outcome was willingness of participants, and any children or older individuals living with them, to receive future COVID-19 vaccines. Logistic regression analyses were used to explore potential factors associated with vaccination willingness. Results A total of 1071 participants were asked about their willingness to receive future COVID-19 vaccines, for themselves and at least 747 children and 375 older individuals (≥60 years old) living with them. The highest proportion of expected willingness to vaccinate was among participants (88.6%), followed by children (85.3%) and older individuals (84.0%). The main reasons for reluctance to vaccinate among 119 participants were doubts regarding vaccine safety (60.0%) and efficacy (28.8%). Participants with a self-reported history of influenza vaccination were more likely to accept COVID-19 vaccines for themselves [adjusted odds ratio (OR) = 1.83; 95% confidence interval (CI): 1.19–2.82], their children (adjusted OR = 2.08; 95%CI: 1.30–3.33), and older individuals in their household (adjusted OR = 2.12; 95%CI: 1.14–3.99). Participants with older individuals in their families were less willing to vaccinate themselves (adjusted OR = 0.59; 95%CI: 0.40–0.87) and their children (adjusted OR = 0.58; 95%CI: 0.38–0.89). Conclusions Participants were more reluctant to accept COVID-19 vaccines for older individuals living with them. The presence of older individuals in the home also affected willingness of participants and their children to be vaccinated.

Abstract Background Cow milk allergy (CMA) is the third most common food allergy that triggers anaphylactic reactions. Lactose intolerence, infantile colic and gastroesophageal reflux are the most common conditions which overlap with CMA causing both over and underdiagnosis. There are no wide population based epidemiological studies for the prevalence of CMA among Egyptian children. We sought to evaluate the prevalence of CMA among infants and preschool children and to correlate the parental reporting of CMA to the available diagnostic tools. Methods We conducted a cross sectional study that included 800 Egyptian children aged 3 months -5 years, who were enrolled consecutively from the primary care units and outpatient clinics of Children’s Hospital, Ain Shams University. Detailed history taking and clinical examination were done and those with suggestive history of CMA were subjected to further evaluation including skin prick test (SPT) and oral challenge test (OCT). Results The study comprised 390 girls (48.8%) and 410 boys (51.2%). Their weight centiles ranged between 5th and 97th percentiles, with median (IQR)=25(5-50) percentiles and mean(SD)=36.1(31.9). CM was introduced at age of 1-12 months, mean (SD): 9 (6) months with median (IQR): 12 (9-12) months. Forty (5%) subjects had suggestive history of CMA, 32 of whom completed their evaluation. The diagnosis of cow milk allergy was confirmed in 8/40 children (20%), comprising 1 % of the whole study sample. CMA was probably excluded at the time of the study in 21 subjects (52.5%), while diagnosis remained undetermined in 11/40 cases (27.5%) (8 refused to undergo SPT & OCT while 3 were lost to follow up). Conclusion The prevalence of CMA in Egyptian infants and preschool children is estimated to be around 1 % with possible overestimation of cow milk allergy diagnosis according to parental reports.

A geographically stratified cross-sectional survey was conducted in 2002 to investigate household-level factors associated with use of mosquito control measures and self-reported malaria in Malindi, Kenya. A total of 629 households were surveyed. Logistic regressions were used to analyse the data. Half of all households (51%) reported all occupants using an insecticide-treated bed net and at least one additional mosquito control measure such as insecticides or removal of standing water. Forty-nine per cent reported a history of malaria in the household. Of the thirteen household factors analysed, low (OR=0·23, CI 0·11, 0·48) and medium (OR=0·50, CI 0·29, 0·86) education, mud–wood–coral (OR=0·0·39, CI 0·24, 0·66) and mud block–plaster (OR=0·47, CI 0·25, 0·87) wall types, farming (OR=1·38, CI 1·01, 1·90) and travel to rural areas (OR=0·48, CI 0·26, 0·91) were significantly associated with the use of mosquito control, while controlling for other covariates in the model. History of reported malaria was not associated with the use of mosquito control (OR=1·22, CI 0·79, 1·88). Of the thirteen covariates analysed in the second model, only two household factors were associated with history of malaria: being located in the well-drained stratum (OR=0·49, CI 0·26, 0·96) and being bitten while in the house (OR=1·22, CI 0·19, 0·49). These results suggest that high socioeconomic status is associated with increased household-level mosquito control use, although household-level control may not be enough, as many people are exposed to biting mosquitoes while away from the house and in areas that are more likely to harbour mosquitoes.
