RESUMO
Development of insecticides resistance mainly hinge with managements techniques for the control of Jassid, Amrasca biguttutla biguttutla. Five insecticides were applied against field collected and laboratory rared jassid populations during the years of 2017 to 2019 to profile their resistance level against field population of jassid through leaf dip method. Very low resistance level was found in jassid against confidor whereas high level of resistance was observed by pyriproxyfen against other test insecticides. Gradual resistance was observed against diafenthiuron. It is concluded that for the management of Jassid repetition of same insecticide should be avoided. The use of confidor may be reduced to overcome resistance against Jassid.
Desenvolvimento da resistência a inseticidas principalmente em dobradiça com técnicas de manejo para o controle de jassid, Amrasca biguttutla biguttutla. Cinco inseticidas foram aplicados contra populações de jassídeos coletados em campo e em laboratório durante os anos de 2017 a 2019 para traçar o perfil de seu nível de resistência contra populações de jassídeos em campo através do método de imersão nas folhas. Nível de resistência muito baixo foi encontrado em jassid contra confidor, enquanto alto nível de resistência foi observado por piriproxifeno contra outros inseticidas de teste. Resistência gradual foi observada contra o diafenthiuron. Conclui-se que, para o manejo do jassid, a repetição do mesmo inseticida deve ser evitada. O uso de confidor pode ser reduzido para superar a resistência contra jassid.

Hydatid cyst disease is a significant health problem for undeveloped and developing countries. Humans are infected by way of contaminated dogs or contaminated uncooked vegetables. Cardiac hydatid cyst disease is uncommon, occurring in approximately 0.5% to 2% of patients with hydatid disease. Most cardiac hydatid cysts are located in the left ventricle and interventricular septum. The rate of pericardial hydatid cysts is (2-10) % of cardiac echinococcosis. Although cardiac involvement is rare, early diagnosis and treatment of this situation is important. Surgical options include sternotomy, thoractomy and video assisted thoracoscopy (VATS). In the present report, a 17-year-old girl with pericardial and hepatic hydatid cyst is described and it has been treated with left VATS for pericardial cyst. In the present patient, the hydatid cyst was located inside the pericardial cavity without myocardial involvement.
RESUMO
Background: Systemic Lupus Erythematosus (SLE) is an autoimmune disorder which affects multiple organs of human including lungs. Objectives: To assess PEFR and FEF25-75 in SLE patients and to correlate them with the duration of the disease. Method: This cross-sectional study was carried out in the Department of Physiology, BSMMU, Dhaka, from January 2010 to December 2010. A total number of 120 female subjects were selected, among which 30 were age and BMI matched apparently healthy subjects for comparison (control) and 90 were patients of SLE (study group). All the patients were matched for age, sex and BMI. Based on the duration of the disease, patients were subdivided into B1 (1-6 months), B2 (2-5 years) and B3 (6-10 years). Controls were selected from the community and the patients from the Out Patient Department (OPD) of SLE clinic, Department of Medicine, BSMMU, Dhaka. (PEFR) and FEF25-75 of all the subjects were measured by a Digital MicroDL spirometer. For statistical analysis Independent Sample ‘t’ test, One way ANOVA test and Pearson’s correlation coefficient test were performed as applicable. Results: The mean percentage of predicted values of lung function parameters in healthy female subjects were within normal ranges. The mean percentage of predicted values of PEFR and FEF25-75 were significantly lower in all study groups when compared to control. Again, the mean percentage of predicted values of PEFR and FEF25-75 were significantly lower in the patients of Group B3 compared to Group B2. Moreover, these comparisons were significantly lower when compared to Group B1. The differences of the mean percentage of predicted value of PEFR, FEF25-75 were non-significantly lower in Group B2 when compare to Group B1. In addition, FEF25-75 were positively correlated with duration of SLE in group B2 but negatively correlated in B3. On the other hand PEFR was negatively correlated with duration of SLE in both B2 and B3. All these values were statistically non-significant. Conclusion: These pulmonary functions decrease in SLE female and the reduction is inconsistently associated with duration of the disease.
RESUMO
This study was designed to compare the blood lipid profile and conventional cardiovascular risk factors in patients with acute coronary syndrome (ACS) and chronic stable angina (CSA). A total of 110 patients, 55 of which were of ACS and 55 with chronic stable angina (CSA) who underwent coronary angiography in the Department of Cardiology, BSMMU, Dhaka were enrolled for the study. Lipid profile and age, sex, diabetes mellitus, hypertension, hyperlipidemia, smoking habit, family history of premature coronary artery diseases (CAD) of the patients were recorded and compared. Mean±SD age of the studied patients was 52.2±10 years. Prevalence of diabetes mellitus (p<0.05) and hypertension (p <0.05) was significantly higher in patients with CSA than that with ACS. Frequency of hyperlipidemia, smoking habit and family history of CAD was similar between groups. Patients with CSA had significantly higher triple vessel diseases (TVD) (p < 0.001) and significantly lower high-density lipoprotein cholesterol (HDLc) (p < 0.05) compared to that of patients with ACS. ACS patients had significantly higher single vessel diseases (SVD) (p <0.001) compared to that of CSA but the distribution of low-density lipoprotein cholesterol (LDLc), total cholesterol and triglycerides were variable between groups. This study showed that CSA patients had substantially higher frequency of having some CVD risk factors with alteration in certain lipid profile parameters and higher number of triple vessels disease than patients with ACS. This might aid in selecting appropriate criteria for angiographic evaluation and better management of patients with coronary artery diseases.
RESUMO
Idiopathic central serous chorioretinopathy (ICSC) is usually seen in young males with Type A personality. Clinical evaluation of the macula with fundoscopy and biomicroscopy, coupled with fluorescein angiography establishes the diagnosis. Indocyanine green angiographic studies have reinformed that the basic pathology lies in choriocapillaries and retinal pigment epithelium. Most of the ICSC resolve completely in four months, and some of them could resolve early with direct photocoagulation of the leaking site. Oral steroids have no role, and could even cause an adverse reaction.
