Knowledge; Awareness; and Practice of the Use of Peak Flow Meters by Physicians in the Management of Asthma in Children

The peak flow meter (PFM) is a useful device in asthma monitoring and in determining the severity of symptoms. Against the background of reported under utilisation of PFMs in the management of asthma and prescription for home use; and the paucity of such data in developing countries; this study was carried out to assess the knowledge; awareness; and practice of physicians on the use of PFMs in the management of children with asthma. The work was a prospective cross-sectional study involving 67 doctors working in the paediatric departments of two government hospitals in Lagos State; Nigeria. The number of doctors varied as not all responded to all the questions. The figures therefore correspond with the number of doctors that responded to the particular issue/question addressed. The survey was conducted with a self-administered structure questionnaire. Information obtained included the availability of PFMs in consulting rooms; knowledge of their use; benefits; frequency of prescription; and constraints in prescribing PFMs for the home management of asthma. Only 13 (20.0) of the doctors (n=65) used the peak expiratory flow rate (PEFR) regularly in the diagnosis of asthma. The designation of the respondents and the years of experience in the management of asthma were significantly related to the frequency of prescription of the PFM (p=0.007; p=0.003 respectively).Non-availability was the highest constraint to PFM use (75.0); followed by the cost of the PFM (51.7). This study revealed that the physicians' knowledge about the PFM was suboptimal. The meters were rarely used in diagnosis nor prescribed for home management by physicians attending to asthmatic children at the two referral hospitals. The cost and availability of the PFM should be addressed by the hospital management

Methicillin resistant Staphylococcus aureus: awareness, knowledge and disposition to screening among healthcare workers in critical care units of a Nigerian hospital.

BACKGROUND: Awareness level about methicillin resistant Staphylococcus aureus (MRSA) is high in the western world but the status in developing countries is not well defined. OBJECTIVE: To assess MRSA awareness level, knowledge and disposition to screening among critical healthcare givers (HCGs) in Nigeria. METHODS: A self-administered questionnaire was used to assess the level of awareness and knowledge of HCGs in critical care units of the University of Ilorin Teaching Hospital, Ilorin, Nigeria on MRSA and their willingness to submit to screening. RESULTS: Only 103 (52.0%) of the 198 participants were aware of MRSA but all were favourably disposed to screening for the organism. Awareness was through hospital rounds 65(63.1%) and journals/ textbooks 35(34.0%), and Many, 120 (60.6%) considered MRSA as a threat in the hospital, while only 27 (13.6%) thought otherwise and 51(25.8%) were indifferent. Most HCGs, 124 (87.9%) reported that there were no MRSA control measures in their respective duty post. The age, cadre of work, and number of years in the hospital's critical care units correlated positively with awareness level. CONCLUSION: Methicillin resistant Staphylococcus aureus awareness level among the HCGs in our hospital is just a little above 50.0% with substantial proportion of them not realizing the medical implication of the organism. However, majority are well disposed to MRSA screening. Inadequate publicity is a major contributor to poor knowledge and awareness. There is need for educational intervention and sensitization programs on MRSA and other infection control techniques for HCGs in developing nations especially Nigeria.

Submucous diathermy of the inferior turbinates in chronic hypertrophic rhinitis.

Twenty patients, 10 allergic and 10 non-allergic, with chronic hypertrophic rhinitis and presenting mainly with bilateral nasal obstruction were subjected to submucosal diathermy of their inferior turbinates. There was significant post-operative improvement clinically, histopathologically and histochemically in the non-allergic group, while the improvement was less obvious in the allergic cases. The post-operative clinical improvement as regards rhinorrhea and sneezing was not as marked as that for nasal obstruction. Evaluation of the results showed that submucous diathermy of inferior turbinates is a good line of treatment for cases of chronic hypertrophic rhinitis, with better results in the non-allergic group of patients.
