Published: June 2022

The study on the semiconducting properties of herbal dye and various parameters of the herbal dye-based device is an important area of research in the coming days. In this work, we have measured the conductivity and Hall coefficient of turmeric dye in solid thin film form. Using the working principle of the Hall Effect, we have measured the Hall coefficient (HC) of this film. It is found that the curves of Hall voltage (VH) –Hall current (HC) and Hall voltage (VH) – Magnetic field (BH) are linear. The Hall coefficient has been estimated from these curves. The average value of the Hall coefficient (R) is 22.64 × 10-4 . The conductivity (σ) of the film is 1.5 10-10 m-1. We have estimated charge carrier density from this parameter, and its typical value is 2.8 23 m-3. We have also prepared a diode using this turmeric dye and extracted reverse saturation current, rectification ratio, ideality factor, series resistance, etc. It has been noticed that the diode exhibits high ideality factor and series resistance. The presence of traps is one of the main reasons for these high values. So, we have also measured the trapped energy of the device considering exponential trap distribution.

Published: June 2022

In this study, the structure and various molecular parameters of 4-bromo-3-(methoxymethoxy) benzoic acid are determined at the B3LYP/6-311++G(d,p) level of theory. Present study provides comparision and discussion of calculated and experimental optimized parameters. The values of descriptors such as ionization energy, hardness, electrophilicity, condensed Fukui function and energy were determined to predict the reactivity of 4-bromo-3-(methoxymethoxy) benzoic acid. The influence of the solvent on reactivity parameters has been studied adopting the PCM model. The analysis shows that solvation alters the values of reactivity descriptors. A vibrational assessment of the molecule has also been performed. To gain a better understanding of the properties of the title molecule, parameters such as the molecular electrostatic potential surface and the HOMO-LUMO band gap have been computed. The dipole moment, polarizability and hyperpolarizability were also estimated to probe into non-linear optical properties of the chemical.

Published: June 2022

Background: Appendectomy, though being performed by both open and laparoscopic methods, there is a lack of consensus regarding which is the most appropriate method. This study will document important variables and parameters to compare therapeutic benefit of laparoscopic Appendectomy (LA) and open Appendectomy (OA). Objective: The study aimed at comparing the short- term outcome of laparoscopic Appendectomy and open appendectomy in cases of acute appendicitis, in terms of postoperative pain and complications, hospital stay, recovery and return to normal activities.
Methods: Whenever there was clinical suspicion of acute appendicitis, the patient was admitted to hospital, relevant history was recorded and clinical examination was conducted, necessary laboratory and imaging studies were performed and patient satisfying the inclusion and exclusion criteria was included in the study. The Appendectomy procedure was attended by the investigator and all relevant perioperative data were recorded.
Results: Post-operative pain was mostly mild in LA group (40%), while in OA, it was mostly severe (38%) and moderate (34%). Postoperative complications were significantly higher in OA than in LA. Hospital stay was longer in OA (7.03 days) than LA (3.49 days). Early recovery and return to full normal activity was noted in LA (5.56 days) than in OA (11.26 days). Moreover, operative time was shorter in LA (56.37 min), than in OA (71.86 min).
Conclusion: Laparoscopic Appendectomy have clear advantages over open Appendectomy in respect to short term results.

Authors: Lslam Md Aminul , Bhuiyan Masfique Ahmed , Haque Razibul , Islam Kazi Majharul , Masum Mohammad , Rahman Md Azizur 
Published: June 2022

Background: Patients with Penetrating Abdominal Injury (PAI) are at risk of harboring life-threatening injuries. Many patients are in need of emergency operative intervention. However, there are some patients who can be safely managed non-operatively. Every patient with an abdominal penetrating trauma should have a thorough clinical examination. Repeating the clinical examination at regular intervals is the cornerstone of selective management, as symptoms and signs that were initially absent may appear later.
Objective: To see the efficacy of serial physical examination in patients with penetrating abdominal injury thus avoiding non-therapeutic laparotomy in the overall management of patients.
Methods: Convenient and purposive 60 PAI patients admitted in casualty block of Dhaka Medical College & Hospital were selected for selective non operative management (SNOM). On admission the abdominal wound was inspected and neither digital nor direct probing of the wound was attempted. Patients selected for admission had an intravenous line established, a thoracic and abdominal X-ray taken and urine and blood samples were taken. If necessary, a nasogastric tube was inserted. Asymptomatic haemodynamically stable patients were admitted for clinical observation in a single unit during which period the patient was examined by a senior surgeon for clinical re-assessment. Patients were discharged when feeding was normal and if there were clear signs of improvement. Results: Over a 6 month period 60 consecutive patients with penetrating abdominal wound were reviewed. In total 52 patients (86.67%) were managed with clinical re-assessment and discharged without laparotomy. Eight patients (13.33%) underwent laparotomy after observation. Small bowel, liver, mesenteric vessels were most frequently affected. Non-therapeutic laparotomy rate was 0%. After laparotomy the morbidity rates were 62.5% (p = 0.92). One local wound infection occurred without prior laparotomy. Average hospital stay after observation was 2.8 days, after laparotomy 9.8 days. Delayed laparotomy did not increase morbidity or hospitalization.
Conclusion: Our experience with penetrating abdominal trauma supports the concept of selective conservatism based on repeated physical examination. In a well-established trauma center this has proven to be highly effective with remarkably low rates of non-therapeutic laparotomies and absence of missed diagnosis of visceral injuries.

A Comparative Study between Patients with Mechanical Bowel Preparation and Patients with No Bowel Preparation in Elective Colo-rectal Surgery
Authors: Ahmed Molla Sharfuddin , Siddique Md Ibrahim 
Published: June 2022

Background: Modern surgical techniques and improved preoperative care has reduced both morbidity and mortality of colorectal surgery but the role of mechanical bowel preparation is recently disputed. Primary colonic anastomosis without mechanical bowel preparation is still considered unsafe.
Objective: One of the objectives of this study was to evaluate pre-operative mechanical bowel preparation in preventing anastomotic and wound dehiscence in elective colon and rectal surgery.
Methods: Fifty patients who were included in this study were randomly divided into two groups (group A & Group B). Group A was the preparatory group and Group B was the non-preparatory group. In preparatory group oral poly ethylene glycol was used for mechanical bowel preparation and in non-preparatory group no bowel preparation done. All patients were operated on by qualified surgeons and followed up for outcome and collected data were analyzed. Results: 80% of the Patients in Group A had adverse effects of bowel preparation like nausea, vomiting, blotting, loose motion and precaution had to be taken for them. All the patients of both groups were given per-operative antibiotics whereas 24 patients of Group A and 23 patients of Group B were given transfusion. 15(60%) patients of Group A had developed post-operative surgical infectious complications. The majority number of patients of Group A had been suffered from surgical site infection (10, 40%) followed by Anastomotic Leak, Intra-abdominal abscess and Peritonitis whereas in Group B 10(40%) patients developed surgical complications.
Conclusion: Mechanical bowel preparation before elective colon and rectal surgery is not so effective in preventing complications and without any mechanical preparation of the bowel colorectal surgery can be done safely.

In Bangladesh, the ground water of almost all the 64 districts are contaminated with arsenic and in some regions the arsenic concentration is above the World Health Organization’s guideline value. Bioremediation is in demand for its removal from water especially in rural areas. In this study, four soil samples were collected from arsenic contaminated areas of Chandpur, Bangladesh. In total 58 bacterial strains resistant to arsenate were isolated. Among them I-34 has the highest arsenate reducing capability. This bacteria showed resistance to high concentration of arsenite (100 mM) and arsenate (300 mM). Its arsenate reducing enzyme is extracellular and showed highest activity at 60 °C. More interestingly, it showed auto-induction metabolism to produce arsenate reducing enzyme. Molecular characterization by 16S rDNA gene sequence analysis revealed that the bacterium is 100% identical to Bacillus megaterium. I-34 appears to be novel arsenic metabolizing bacteria within this genus. The bacterial isolate can be exploited for the study of possible bioremediation of arsenic containing water and have a potential impact to reduce the arsenate into arsenite form.

Prevalence of birth abnormalities and congenital malformations in progenies from parental consanguinity in Rajshahi City Corporation area, Bangladesh
Authors: Islam M Saiful , Mustari Sharmin 
Published: June 2022

In a series of two separate studies during January through August 2018, various birth abnormalities (BA) from 178 clinical cases and congenital malformations (CMF) from 70 consanguineous marriages (CM) and 100 non-consanguineous marriages (NCM) within the Rajshahi City Corporation (RCC) area have been recorded, analyzed and interpreted. Results demonstrate that frequencies of miscarriages (5.69 vs. 3.00), stillbirths (3.85 vs. 1.00), postnatal deaths (8.97 vs. 1.00), preterm deliveries (29.49 vs. 38.00) and breech births (6.41 vs. 4.00) were significantly greater in CM compared to the NCM counterparts. In addition, both gestational ages and live birth weights of the children from CM were significantly lesser than those recorded from the NCM couples. Of 205 children derived from 70 CM couples 67 were suffering from various CMF, the remaining 138 children were normal. Compared to this, only 2 out of 267 children were affected from 100 NCM couples. Mental retardation (MR) represented the highest CMF (n= 37), followed by cerebral palsy (CP; n= 16), crossed-eyes (CE; n=4), blindness (BL) and microcephaly (MC; n= 3 each), deaf-mute (DM; n= 2), and Down’s syndrome (DS) and syndactyly (SD; n= 1 each). In contrast to the CM cases, the NCM couples had only two affected children, one crossed-eyed girl and the other polydactylous boy. The overall frequency of CMF in CM (32.68) was much higher than that in NCM cases (0.75). In relation to parental consanguinity, the importance of genetic counselling and pre-implantation screening relevant to the present findings has been emphasized in this report.

In children, primary malignant tumors of the gastrointestinal (GI) tract are rare and accounts less than 5% of all pediatric neoplasms.1 Non-Hodgkin’s lymphoma (NHL) remains the most common malignancy of the GI tract in children.2 Moreover small intestine (PLI) is very uncommon. They are different in anatomic distribution and histologic appearance compared to common patterns in adult cases. The disease is rare and having variable clinical presentation that delayed early detection when the possibility of cure exists. The common presentations of PLI are bowel obstruction and intussusception.3,4 NHL of the gastrointestinal tract usually arises in the submucosal lymphoid tissue of the ileocecal region, extendtransmuraly, and involve local mesenteric lymph nodes extensively, forming a bulky abdominal mass. NHL most frequently involved the ileocecal valve (35.8%), followed by the small bowel (31.3%), large bowel (19.4%) and multiple gastrointestinal involvements (13.4%).5 Here we present a case report to show the scenario of a patient suffering from NHL where diagnosis was delayed. The child was suffering from recurrent abdominal pain (RAP) and various treatment was offered but he could not improve. Finally, he was diagnosed as a case of primary non-Hodgkin's lymphoma of the small intestine (PLI). Though PLI is a very uncommon malignancy in childhood.

Objective: This study sought to evaluate the correlation of left ventricular ejection fraction (LVEF) with Signal – Average Electrocardiogram (SAECG) in patient with acute myocardial infarction.
Background: Post MI risk stratification is still a debatable issue. Appropriate investigation to ascertain the patient at risk of sudden cardiac death is sometimes difficult. Abnormalities in the SAECG have been determined to be independent predictors of risk of developing ventricular arrhythmias in patients convalescing from myocardial infarction. Correlation of LVEF with SAECG will identify the small group of patient at risk of fatal arrhythmia.
Method: This observational study was carried out in the cardiology center, Combined Military Hospital, Dhaka cantonment during the period of January 2010 to January 2011. Patient with first acute myocardial infarction within 7 days of sustaining acute myocardial infarction were included in the study. All three parameters of SAECG (Total QRS duration, Low Amplitude Signal (LAS) under 40μvolt, Root - mean -square (RMS) voltage of last 40 msec) were recorded, and basing on the results, patients were grouped into normal or abnormal SAECG.
Result: A total of 106 patients of acute MI were studied. Mean age of the patients were 54(SD±10.5) years (range 34 to 90 years). Only 13(12%) patients were female with male to female ratio of 7.15:1. 32% patients were thrombolysed & abnormal SAECG was more in patients who were thrombolysed (p value<0.05) but logistic regression analysis showed no significant association. Smoking had significant association with abnormal SAECG by univariate analysis (p value<0.05) but logistic regression analysis showed no significant association with smoking and sex (p value >0.05). 46% patients had inferior/inferoposterior myocardial infarction. Abnormal SAECG was more among patients with inferior MI (p <0.05). Mean LVEF was 45.81% (SD±9.68). Correlation of LV function was assessed by both Pearson’s correlation and Ç2 test but no significant association was seen. Logistic regression analysis showed the similar result.
Conclusion: In our study, no correlation was found between abnormal signal-averaged ECG and left ventricular ejection fraction following acute myocardial infarction. Further large, multi center study with more selective variables is required to find out any association of SAECG and LV ejection fraction.
