ABSTRACT
Background: Mosquito repellants and many other insecticides contain Pyrethrins and Pyrethroids. Pyrethroids are the most commonly used household insecticides derived from Chrysanthemum flowers. These insecticides can cause several clinical problems like allergies, asthma attacks, wheezing and bronchospasm. Despite all associated side effects, pyrethroids are still considered to be least toxic. In the present study the effects of pyrethroids on lung function parameters of school children were Analyzed
Method: The study was conducted at Government Girls Primary School, Sita Nagar, Karachi including 50 children 6-10 years old. They were divided equally into two groups. Group A [exposed to insecticidal spray] and group B [exposed to combustible coil]
Result: The correlations between the insecticides [pyrethroids], and the spirometry variables [FVC, FEV1, PEF, and FEV1/FVC ratio] by linear regression analysis confirmed that pyrethroids had a strong correlation with the spirometric values under study exemplified by the significant decrease in FVC and FEV1 after exposure to insecticidal spray
Conclusion: Highly significant values of FVC and FEV1 were observed after combustible mosquito coil exposure. There was no association between FEV1/FVC ratio, PEF, and exposure to insecticidal spray and mosquito coils
ABSTRACT
To find relationship between peptic ulcer [PU], ABO blood group, smoking, age and sex of patients. An observational and prospective study was made. The study was carried at Bolan Medical College Complex Hospital Quetta from March 2001 to November 2002. 100 peptic ulcer patients confirmed with video endoscope were included. ABO blood group was determined by slide test method. Age, sex and smoking status were also recorded. Out of 100 PU patients 90 were males, 36 had blood group 0, 27 had group B. Amongst 10 females, 7 had group 0 and 2 had B group. Smokers having PU were 62, group 0 was dominant [n=28] followed by group B [n=17]. In 38 non-smokers, group 0=15 and group B=12. At 25-35 years of age, PU was found in 38 cases with blood group 0=23, B=7, A=5, AB=3. Blood group 0 is common in peptic ulcer that is higher in males, smokers and at young age group
