A variety of surgical technique have been discovered for pediatric inguinal hernia such as transperitoneal closure of the deep inguinal ring without opening the superficial ring and the transinguinal approach, ligation of hernial sac at the deep ring. The present study has been designed to compare the Laparoscopic repair and Open repair of pediatric inguinal hernia. Methods: This prospective comparative interventional study was carried out in department of pediatric surgery, DMCH, Dhaka, during the period of January '09 to March '10. Total sixty patients were included in this study. Among them 30 patients in Group-L were repaired by laparoscopic procedure and another 30 patients in Group-O were repaired by open procedure. Both groups were followed-up for three months. Results: among sixty patients early post-operative complications were almost same and there was no recurrence in any groups. It was found that pain relief is earlier in laparoscopic repair than open repair and also cosmoses. Moreover laparoscopy can detect the contralateral hernia or contralateral persistent process us vaginalis and able to repair it in the same setting. Conclusion: laparoscopic repair of pediatric inguinal hernia seems to be a better technique than open repair with regards to early pain relief and cosmoses. By which contralateral inguinal hernia is detectable and repairable.
Chronic Obstructive Pulmonary Disease (COPD) is a major cause of chronic morbidity and mortality ... more Chronic Obstructive Pulmonary Disease (COPD) is a major cause of chronic morbidity and mortality throughout the world. Many people suffer from this disease for many years and die prematurely from it or its complications. COPD is a preventable and treatable pulmonary disease. In early stage, diagnosis of COPD is difficult because sign & symptoms are minimum. Only history of mild dyspnea, cough and/or sputum production or prolong smoking, exposure to occupational dusts or biomass fuels are present without any sign. Spirometry is the tool to diagnose COPD. If we can diagnose COPD in early stage then it is treatable and can prevent progression of the disease. Spirometry is a simple tool to diagnose COPD at any health care level. So this study was done to diagnose COPD in early stage among smokers. This study was carried out in Department of Medicine (Indoor & outdoor) of Rajshahi Medical College Hospital from March, 2010 to February, 2011. 255 smoker having exposure to >10 pack year ...

A total number of 144 patients of anterior and distal penile hypospadias with/without chordee were evaluated by follow up study in our hospital and private hospital from January 2010 to July 2013. Redo cases, complex hypospadias and proximal hypospadias were excluded. Simple Random sampling technique was followed to the patients were grouped into Group-A (72 patients) and Group-B(72 patients) on the basis of age of the patients. Both Group-A, age between 6 to 18 months and Group-B, more than 18 month to 14 years were operated by Snodgrass procedure. We did follow up 12-24 months postoperatvely. It can be recommended for repair of anterior and distal penile hypospadias within 6 to 18 months whenever the question of post urethroplasty cosmosis, wound disruption and formation of urethra cutaneous fistula.

While the Yield Loss (YL) from this disease is reported in many countries, there exists no tool to instantly estimate the YL by visual field inspection. This study developed a simple model, FLYER, for this purpose. The model is run by two inputs: (i) fraction of productive but diseased tillers in a field and (ii) averaged number of smut balls present in the diseased panicles. FLYER was developed using data from Bangladesh, India and Japan. The driving algorithm of the model, the yield reduction in a diseased panicle as a function of number of smut balls present in the panicle, was validated with additional data from Bangladesh and Japan. When tested with independent data from fields infected naturally by RFSm, FLYER closely estimated the Yield Loss (YL, %) against observed datasets from Bangladesh (Root Mean Squared Deviation (RMSD) = 1.15% YL), Egypt (RMSD = 1.65% YL) and India (RMSD = 1.68% YL). This model could contribute to rapid assessment of regional and variety-specific yield loss and strategic management of the disease on a field-by-field basis.

But surgery remains the mainstay for management of IHPS. RamstedtÂ’s pyloromyotomy was described almost over a hundred years ago and to date remains the surgical technique of choice. An alternative and better technique is the double-Y pyloromyotomy, which offer better results for management of this common condition.Methods: A prospective comparative interventional study of 40 patients with IHPS was carried out over a period of 2 years from July 2008 to July 2010. The patients were divided into 2 equal groups of 20 patients in each. The study was designed that all patients selected for study were optimized preoperatively regarding to hydration, acid-base status and electrolytes imbalance.

Circumcision is a surgical procedure performed for centuries for medical, religious and several other reasons. Circumcision is the most common surgical procedure performed in boys through out the world. Meatal stenosis is one of its late complications. We evaluated the topical use of lubricant jelly (Vaseline- petroleum jelly) after circumcision in boys in order to reduce or prevent the risk of meatal stenosis.Objective: To see the effectiveness of use of lubricants and to determine the functional outcome, that is prevention of post circumcision meatal stenosis.Materials and Methods: A randomized control trial was performed, in which two groups of boys younger than two years old underwent circumcision according to dissection (sleeve) method . The parents in the study groups were strictly instructed to use petroleum jelly on the meatus and circumcis...

Anastomosis study with a reference isolate confirmed that all the isolates belonged to R. solani. Significant variation was observed in sclerotial size, shape and distribution. Un-weighted pair group method with arithmetic mean dendrogram constructed based on the Gower's general similarity coefficient showed that these isolates were grouped into four clusters at the 0.68 similarity coefficent according to morphological characters. Cluster I was a major cluster consisting of 13 isolates, while clusters II to IV consisted of 1 or 2 isolates. Analyses by variable number of tandem repeat and amplified fragment length polymorphism markers showed that the isolates were grouped into five and three clusters at a similarity coefficient of 0.64 and 0.69, respectively. Although most of the variability was found between isolates from different regions as expected, significant variation was observed within the isolates collected from similar agro-ecological regions. Our results suggest the presence of different races of R. solani within the same local geographic regions.

In the search of resistant source against P. oryzae, resistant gene (R-gene) was assessed by (i) host-pathogen interaction and (ii) PCR-based screening at the laboratory of Bangladesh Rice Research Institute. One hundred and forty four plant materials were classified into 10 cultivar groups (CG) based on their reaction patterns to four distinct blast isolates (SDBI; standard differential blast isolate) H-11-64, H-1-8, H-1-1 and H-11-67. The reaction patterns of plant materials to these four standard blast isolates indicated presence of Pish, Pi9, Pita2 and Pita genes and their combination in the genetic background of tested plant materials. Gene specific primer 195R-1/195F-1, Pita440 (YL153)/Pita440 (YL154), OSM89 and AOL45/AOL48 were used to identify and confirm the presence of Pi9, Pita, Pita2 and Pish genes in plant materials, respectively through PCR-based assay. Plant materials, H13, H23, H25, H35, H47, H49, H136, H138 harbored all three genes, Pita, Pita2 and Pish in their genetic background. The Pi9 gene together with Pita2 was detected in local rice cultivar H100 and H129, which were confirmed by DNA analysis in PCR assay. These materials could be used in gene pyramiding in promising high yielding cultivar for durable blast resistance.
