AbstractIntroduction:Nasal polyposis associated with aspirin-intolerant asthma tends to be difficult to control, with frequent recurrences. We examined the effect of intranasal lysine-aspirin administration on resistant nasal polyps of asthmatic, aspirin-intolerant patients, when used in addition to routine therapy.Patients and methods:Thirteen patients with asthma and intolerance to aspirin were recruited. All but one had undergone numerous polypectomies and were uncontrolled on standard therapy with intranasal corticosteroids, leukotriene receptor antagonists and nasal douching. Aspirin treatment involved one drop (100 µl) of 30 mg/ml lysine-aspirin solution to each nostril, initially daily, increased every two or three days up to a maximal of 18 drops (54 mg lysine-aspirin) a day. Nasal symptoms, nitric oxide level, nasal inspiratory peak flow rate, peak expiratory flow rate and nasendoscopic grading were assessed prior to therapy and three months later. We also compared the change in endoscopic polyp scores during three months of lysine-aspirin administration with the changes which had occurred during the three months prior to administration (during which time other therapies had been identical).Results:Nasal blockage symptoms tended to decrease; other nasal symptoms were unchanged. Significant changes were seen in nasal inspiratory peak flow rate (103.3 ± 18.9 and 140.0 ± 16.7 l/min before and after aspirin, respectively; p = 0.014), but not in peak expiratory flow rate (438.7 ± 33.4 and 440.0 ± 28.4 l/min before and after aspirin, respectively; p = 0.700). Nasal nitric oxide levels rose significantly (in both sides, p = 0.028). Expired chest nitric oxide levels did not change. Nasal polyp scores on nasendoscopic examination were significantly reduced (right side, p = 0.027; left side, p = 0.018). Compared with the preceding three months, adding intranasal lysine-aspirin application had the effect on decreasing nasal polyp volume (right side, p = 0.031; left side, p = 0.016).Conclusion:This open study suggests that intranasal lysine-aspirin administration reduces nasal polyp volume in aspirin-intolerant patients, without any adverse affect on concomitant asthma. This was a preliminary study and should be followed by a placebo-controlled, double-blind trial.

Predicted Values

Peak Expiratory Flow Rate (PEF) is a simple and reproducible indicator of ventilatory function.1 It is the maximal airflow sustained for at least 10 msec during a forced expiration after deep inspiration. PEF is easy to measure with the Wright Peak Flow Minimeter. Results from this simple lightweight instrument correlate well with those from the older, bigger model.2 Predicted values vary with age, sex and height in adults;3,4 in children they are related to height alone.4,5 It is usual to record the best of three readings.

Background: In this era of globalization one of the growing industries is the construction industry and there are various occupational problems faced by the workers especially in Asian countries mostly in India; the problems are related to both physical and mental health. All the construction sites generate high concentration of dust particles from cement, silica, asbestos, concrete, wood, stand and stand that causes respiratory problems in the workers. PEFR is the maximum air that is generated after forceful expiration, after full lung inspiration. So if there is any accumulation of dust particles the PEFR decreases as the elasticity of lungs to recoil is distrusted due to the lodged particles. Material and Method: A descriptive observation study was carried out on 50 building construction workers. The purpose of the study was explained and informed consent was taken. The PEFR was measured using peak expiratory flow meter. The data was analyzed using standard statistical software. Result: The procedure of using peak flow meter that was carried out for 3 times and the highest value from the three was considered as peak flow rate, using statistical method mean and standard deviation were calculated. The mean of Peak Expiratory Flow Rate is 321.1 L/min. Conclusion: This study concluded that the peak expiratory flow rate is reduced in building construction workers those who are working for than 2 years on the construction sites. Key words: construction workers, occupation diseases, PEFR, peak expiratory flow meter.

Home-monitoring of peak expiratory flow rate using the mini-Wright peak flow meter is a useful technique for determining whether or not unexplained respiratory symptoms are caused by asthma. It is of particular value when airflow obstruction cannot be demonstrated at the time of consultation.

ABSTRACT Peak expiratory flow rate (PEFR) is a simple, reliable, and easily reproducible and measurable lung function test. It has not been formally assessed whether the PEFR values measured with peak flow meter are in close correlation with the values measured by digital spirometer. The present study is carried out to determine whether there is a significant difference between the PEFR values derived from digital spirometer and peak flow meter in patients with respiratory symptoms.

Ventilatory Lung Function

Peak expiratory flow rate (PEFR) is the maximal expiratory flow rate sustained by a subject for at least 10 milliseconds expressed in Litre per minute (L/min). PEFR is a simple, reliable, reproducible and easily measurable ventilatory lung function test. This simple test had been measured by various types and shapes of instruments for long since, now mini- Wright peak flow meter is widely used to measure the of PEFR values. Mini-Wright peak flow meter is cheap, easily portable and reproducible device for PEFR even below the age 5 years. Different countries use their own nomogram or prediction equation to find out mean PEFR values of particular height. Similarly, the prediction equation for calculation of PEFR values of Bangladeshi boys and girls are 5.96XHeight-495 and 5.70XHeight-479 respectively. Peak expiratory flow rate is very useful tool for diagnosis, management and follow up of reversible airway diseases.

The study determined gender variation on cardiopulmonary parameters-blood pressure, pulse rate, respiratory rate and peak expiratory flow rate of residents in gas flaring communities compared with non-gas flared communities. The ex post facto study carried out using a stratified random sampling method involving five hundred and four (504) residents in the gas flaring communities and five hundred (504) in the non - gas flaring communities comprising 564 males and 444 females. Samples for this study were taken from five states in the South-South geopolitical states of Nigeria. The electronic blood pressure kit was used to measure blood pressure and respiratory rate while the peak flow rate was measured with a peak flow metre and respiratory rate was measured manually. Data generated were expressed as mean ± SD. Significance difference between means was determined by student t-test and one-way analysis of variance (ANOVA). SPSS 20 software was used for statistical analysis. A level of p≤0.05 was accepted as significant. Findings indicate that mean diastolic pressure was higher in males (10.96%) than females (5.05%). The pulse rate (36.07%) and the respiratory rate (19.38%) of the female residents in the gas flared environments was significantly (p<0.05) higher than that of the male residents (13.53% and 13.64% respectively), with the female subject more impacted. The mean Peak Expiratory Flow Rate was higher in male (11.06%) residents with females (9.7%) more impacted. This study has shown that gender variation impacted on cardiopulmonary parameters of residents in gas flaring communities in south-south Nigeria
