    ABSTRACT: An intervention study was carried out in the department of paediatrics of Mymensingh Medical College Hospital, Mymensingh to compare the clinical efficacy of Azithromycin in the treatment of childhood typhoid fever with that of cefixime for a period of one year from January 2011 to December 2011. A total of 60 cases of typhoid fever were enrolled in to a randomized clinical trial and was divided into two groups. The inclusion criteria of the cases were: Documented fever for more than 4 days plus two or more of the following clinical features: toxic physical appearance, intestinal complaints, coated tongue, ceacal gurgling, hepatomegaly and splenomegaly, diarrhoea and constipation plus positive Widal test and/or blood culture positivity. Patients who had complication like GIT heamorrhage; intestinal perforaion and/or shock were excluded from the study. Data were collected in a structured questionnaire. Azithromycin was given at a dose of 10mg/kg/day for a period of 07 days Cefixime was given at a dose of 20mg/kg/day in two divided dose for 14 days. The mean time of defervesence was 4.05+1.14 days with azithromycin and 3.41+0.95 with cefixime respectively. The minimum defervesence time was 02 days and maximum defervesence time was 07 days. Clinical cure rate was 87% in azithromycin group and 93% in cefixime group. No serious adverse effect was noted related to azithromycin and cefixime therapy except nausea, vomiting, diarrhoea and jaundice. It was found that azithromycin is almost as effective as cefixime in the treatment of typhoid fever.

    ABSTRACT: This study was done to determine the effects and outcome of inhaled budesonide in addition to standard management of asthma exacerbations in pediatric age groups. A randomized, double-blind, placebo controlled trial was done in a tertiary care urban hospital. Sixty six children aged 5 to 15 years with moderate to severe asthma exacerbations were eligible. All patients received a single dose of prednisolone 1mg/kg orally as first dose of systemic corticosteroids and then salbutamol (0.15mg/kg) and ipratropium bromide (500mcg) was nebulized every 20 minutes for 3 doses and then hourly for 2 hours as a part of standard treatment of asthma exacerbations. The intervention was 2mg (4mL) of budesonide or 4mL of normal saline which was nebulized immediately after the 1st dose of nebulized salbutamol and ipratropium bromide. The baseline characteristics of the budesonide group (n=33) and placebo group (n=33) were similar, but at 1 hour, 2 hour and 3 hour PEFR, respiratory rate, pulse rate, SaO2 and asthma score were significantly improved in the budesonide group compared to placebo group (p<0.01). The positive immediate effect of nebulized budesonide added to standard treatment of asthma exacerbations is an encouraging finding for further investigations of its routine use in the treatment of asthma exacerbations in children.

    ABSTRACT: This prospective study was conducted in rheumatology clinic under the department of medicine of Bangabandhu Sheikh Mujib Medical University from December 2004 to December 2005 to asses the efficacy, safety and compliance of subcutaneous methotrexate (MTX) in active rheumatoid arthritis (RA) patients. A total of 92 active rheumatoid arthritis patients according to American College of Rheumatology (ACR) criteria were recruited for the trial for six months. Among them 46 cases belonged to injectable MTX group and 46 cases belonged to oral MTX group. Mean±SD age of patients was 45.54±12.42 vs. 44.63±13.99 years in subcutaneous group and oral group respectively. In the subcutaneous group 41 were female and 5 male; in the oral group 34 were female and 12 male. Mean duration of the disease was 49.74 months in subcutaneous group and 49 months in oral group. RA test was positive in 35 cases in both groups whereas Rose Waaler test was positive in 19 patients in subcutaneous group and 14 patients in oral group. At 24 week, response rate of ACR 20 was significantly higher in subcutaneous MTX than oral MTX group (93% vs. 80%, p=0.02). Similarly ACR 50 response was significantly higher in subcutaneous MTX than in oral group (89% vs. 72%, p=0.03). ACR 70 response was not significantly higher in SCMTX group then oral group (11% vs. 9 %, p=0.72). Adverse effects were relatively less in subcutaneous MTX and most common side effects were nausea (37% vs. 63%), vomiting (11% vs. 30%), dyspepsia (29% vs. 48%), dizziness (4l% vs. 52%) and alopecia (72% vs. 85%). The results of the study demonstrated that subcutaneous MTX was significantly more effective than oral MTX at the same dosage in active Rheumatoid arthritis patients with no increase in side effects.

    ABSTRACT: Text information recognition is very important because of its vast application. Also for the digitalized system, now a day's in many applications numeric characters are represented in a digital manner i.e 7-segment representation. And recognition of the digital numerical character is getting more popularity day by day. In this paper we proposed a new method for recognizing the 7-segment numeric character. For this purpose we take each segment as a video frame input by web-cam using a red colored object. And then we apply our proposed algorithm which works into three steps: 1) detecting the red color from a frame and finding the frame either it is a row frame or column frame 2) applying a process called numeric character grouping which is done to set the frames into a certain category 3) and then according to the position of row and column of the segment or number of row and column of the segment, a particular numeric character is recognized. The results of the experiments are very promising. In our proposed method, if the frames can take properly then the recognition rate is 100%.

    ABSTRACT: In transit system, military, residential area and restricted area video surveillance system is getting more popular for motion detection and object extraction. Background updating process is the most important feature for motion detection in video surveillance system. In this paper, we proposed a novel algorithm for updating the background and therefore detection the motion of an object for a fixed video surveillance system. In our proposed method video frames are taken from a surveillance camera and then for updating background previous 40 frames from the video frames are used. Here pixel wise comparison is done for the previous frames so that maximum common pixel values are stored to get a temporary background. When the temporary background is obtained then it is compared to the last frame's pixel values and the common pixel values are stored as the permanent background. The pixel values which are not common to the both frame then these values are taken from the previous permanent frames which are common with the last frame. Now again if there is any mismatched pixel value remains then the temporary background's pixel value is stored as permanent background for this position. Finally we get the permanent background as an updated background. And now for motion detection, the next frame's pixel values are subtracted with the permanent background, if the value goes beyond a threshold value then there the object motion is detected. We have applied this method for different video datasets and obtained interesting and promising results.

    ABSTRACT: In human brain the neurons are excited in a dynamic way. The response of different neurons varies widely because of the variation of electrical signal in every neuron. Backpropagation(BP) is a training algorithm where the learning of the Neural Network (NN) is done by a constant learning rate (LR). But to replicate the human brain function, the learning rate should be changed as the excitation of different neurons. In this paper a new learning algorithm is proposed called Hanning Window Neural Network (HWNN) to train the network. Here the window function is used to make the learning rate dynamic called Hanning learning rate (HLR) and for this dynamic learning rate the neural network outperforms than the existing BP algorithm. HWNN is extensively tested on five real world benchmark classification problems such as ionosphere, australian credit card, time series, wine and soybean identification. The proposed HWNN outperforms the existing BP in terms of generalization ability and also convergence rate.

    ABSTRACT: Tuberculosis (TB) is a major public health problem in most developing countries. The present study was carried out among 100 clinically suspected pulmonary TB patients. One hundred sputum specimens were collected one from each of the suspects attending DOT'S corner of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. The aim of the study was to evaluate the sensitivity and specificity of a polymerase chain reaction (PCR) based method detecting IS6110 sequence present in all Mycobacterium tuberculosis strains using sputum samples in comparison to culture on Lowenstein-Jensen mediums. The PCR was done using primers mtb1 & mtb2 which commonly target an insertion sequence of the organism (IS6110). Out of 100 samples, 18 (18%) showed PCR positive, whereas culture in Lowenstein-Jensen media were positive in 19(19%). In PCR 1 was false negative but none was false positive. In present study, sensitivity and specificity of PCR found 94.74% and 100% respectively. Analyzing the findings of the present study, it can be concluded that the PCR technique is a rapid and alternative method of culture on Lowenstein-Jensen medium for the diagnosis of pulmonary tuberculosis. In the present study, only presence or absence of M. tuberculosis was determined.

    ABSTRACT: Chlamydia trachomatis is an obligate intracellular gram-negative bacterium which is the most prevalent cause of bacterial sexually transmitted infections (STI). The present study was carried to diagnose genital Chlamydia trachomatis infection among women of reproductive age, attending Mymensingh Medical College Hospital, during July 2009 to June 2010 by Immunochromatographic test (ICT) and Polymerase chain reaction (PCR). A total of 70 females were included in this study. Out of 70 cases 56 were symptomatic and 14 asymptomatic. Endocervical swabs were collected from each of the cases and examined by Immunochromatographic test (ICT) for antigen detection and Polymerase chain reaction (PCR) for detection of endogenous plasmid-based nucleic acid. A total 29(41.4%) of the cases were found positive for C. trachomatis either by ICT or PCR. Of the 56 symptomatic cases, 19(33.9%) were found ICT positive and 17(30.4%) were PCR positive. Among 14 asymptomatic females, 2(14.3%) were ICT positive and none were PCR positive. Though PCR is highly sensitive but a total of twelve cases were found ICT positive but PCR negative. It may be due to presence of plasmid deficient strain of C trachomatis which could be amplified by ompA based (Chromosomal gene) multiplex PCR.

    ABSTRACT: An improved human authentication process using knuckle surface for personal identification has shown promising results. The texture pattern produced by the finger knuckle bending is highly unique and makes the surface a distinctive biometric identifier. In this paper we proposed a new approach for efficient and more secure personal identification using knuckle surface. A specific data acquisition device is constructed to capture the finger knuckle surface images, and then an efficient finger knuckle print algorithm is presented with trained neural network. The finger back surface images from each of the users are normalized to minimize the scale, translation and rotational variations in the knuckle images. The main attraction of this proposed method is that a hybrid feature selection method of Lempel-Ziv Feature Selection and Principle Component Analysis is used for feature extraction and an artificial Neural Network based on Scaled Conjugate Gradient is used for the recognition. The experimental results from the proposed approach are promising and confirm. Compared with the other existing finger-back surface based biometric systems, the proposed system is more efficient and can achieve higher recognition rate in real time.

    ABSTRACT: The present study was carried to diagnose genital Chlamydia trachomatis infection among women of reproductive age, attending Mymensingh Medical College Hospital, during July 2009 to June 2010 by Polymerase chain reaction (PCR). A total of 70 females were investigated including 56 symptomatic and 14 asymptomatic cases. Endocervical swabs were collected and dipped in 500μl Tris buffer. Polymerase chain reaction (PCR) amplification was done for detection of endogenous plasmid-based nucleic acid. A total 17 out of 56 of the symptomatic cases (30.4%) were positive for C. trachomatis and none were found positive among the 14 asymptomatic cases. These findings suggest high prevalence of C. trachomatis infection among this group of population.
