ABSTRACT
Background: Allergic rhinitis is predecessor of Bronchial asthma in most of the cases. Present study was aimed to understand the prevalence of the impaired spirometric changes in patients with allergic rhinitis and to find association with various demographic factors, sputum eosinophilia and eosinophil count in the blood with the impaired Spirometry of these patients.Methods: Authors conducted a cross sectional study among the patients of allergic rhinitis presented to us in our outpatient department from January 2016 to July 2017. The patient’s with allergic rhinitis either newly diagnosed or already on treatment were included in the study. Standard guidelines as given by ARIA were followed in defining a case of allergic rhinitis. The detailed clinical history was taken, and examination was performed of all the patients and documented. Spirometric evaluation was done using the standard guidelines by a desktop based Spirometry.Results: The mean age of the study subjects was 30.22±13.13 years with male: female ratio of 0.96. The mean duration of the allergic rhinitis in our study was 3.86±3.34years. The most common complaint was itching sensation of nose followed by paroxysmal sneezing and watering of eyes. About 22.15% of the study subjects have impaired Spirometry. Upon bronchodilator therapy 30% of the study subjects had significant reversibility in FEV1.Conclusions: About ¼ of present study subjects had impaired Spirometry and about 30% of them had reversibility after bronchodilator therapy. Authors also found that the higher age study subjects had significantly higher impaired Spirometry; persistent allergic rhinitis patients had higher impairment of Spirometry and the patients with higher the sputum eosinophilia had higher impairment in Spirometry.
ABSTRACT
CONTEXT: The distribution of different types of lymphoma varies across geographic regions. AIMS: The present study was done to understand the occurrence of nodal lymphomas in a referral hospital of Mangalore city. SETTINGS AND DESIGN: Descriptive study. SETTING: The present study was conducted on 95 lymph node biopsy specimens, received in a referral hospital of Mangalore city. MATERIALS AND METHODS: All cases of nodal lymphoma diagnosed between January 2007 and June 2010 in a referral hospital of Mangalore were selected for the study. The patients age and clinical details were obtained. Immunophenotyping was done for all cases of NHL and selected cases of HL. IPI score for NHL was noted and correlated with the outcome. STATISTICAL ANALYSIS USED: Chi square test was used. RESULTS: Out of the total 95 cases of nodal lymphoma 37 (39%) were HL while 58 (61%) were NHL. Classical HL was diagnosed in 35 cases (37%) while 2 cases (2%) were diagnosed NLPHL. B cell lymphoma formed 72% of NHL. Follicular lymphoma accounted for 28% of all NHL. T cell lymphoma formed 28% of NHL. CONCLUSIONS: In conclusion the following points are significant about the distribution of lymphomas in a referral hospital of Mangalore city. The incidence of NSHL is higher while national data suggests MCHL as the most common subtype. The incidence of FL as well as T cell NHL is much higher when compared to national incidence. The epidemiological factors for this high frequency (either genetic or environmental) needs to be studied further.
ABSTRACT
The question of an analogue evolution of plant - insect interaction in gymnosperms has remained unanswered until recently, in spite of indications of insect pollination in the extant cycad genera. Earlier observations on insect pollination have now been verified by convincing experiments with several cycads in which anemophilous pollination was excluded. Insects have long been known to visit cycad cones and now it is established that in rest of the cycad species where both male and female reproductive organs are organized in compact cones, these insects help in the pollination. But Cycas is the only genus where female megasporophylls do not form a cone and its pollination mechanism has not been fully comprehended. The present investigation was carried out in the natural habitats of Cycasspecies from the Western Ghats, India. Five coleopteran insects were found abundantly in the male cones of Cycas and our observations on the role of these insects led us to believe that Cycas among cycads which appear to be true remnants of pteridospermous line have somehow has also maintained mutualism with the primitive plant chewing insects like coleopterans couldbe the results of an ancient co-evolution.
