RESUMEN

Hypertension (HTN) is an important cause of cardiovascular mortality and the prevalence of hypertension is increasing particularly in middle- and low-income countries including Bangladesh. No data are available for the prevalence of hypertension among the government employees in Bangladesh. In this cross-sectional study, conducted from 30 October to 31 December 2016, 1219 government employees aging ≥18 years working in Rangpur city were evaluated for the presence of HTN and its risk factors. Socio-demographic and anthropometric data, data on the presence of various known risk factors of hypertension were collected. Hypertension was defined with systolic BP ≥140mmHg and/or diastolic BP ≥90mmHg or those getting treatment for hypertension. Statistical analysis was done by using SPSS version 23.0; odds of hypertension among subjects with risk factors were calculated and p ≤0.05 was considered to be statistically significant. The prevalence of hypertension was 38.3% among the study subjects. Significantly higher odds of having hypertension were observed in study subjects with the age groups of 35-49 (OR 2.12, 95% CI: 1.51-2.99, p<0.001) and ≥50 (OR: 4.96, 95% CI: 3.43-7.18, p<0.001) years than age group <35 years. Employees who were averagely satisfied and not satisfied for their jobs also had higher odds (OR: 1.38, 95% CI: 1.00-1.91, p=0.049 and OR: 1.48, 95% CI: 3.43-7.18, p=0.337) of having hypertension than fully satisfied ones. Having diabetes mellitus was found to increase the odds (OR 2.12, 95% CI: 1.51-2.99, p<0.001) of hypertension. Male gender, urban/suburban residence, not doing physical exercise, sedentary/light working habit, overweight/obesity also increased the odds of having hypertension though these were not statistically significant. There is a high burden of hypertension among the government employees in Rangpur city. Age, job satisfaction and diabetes were independent risk factors of hypertension.

RESUMEN

This paper presents a new framework for determining the Stillinger-Weber (SW) potential parameters for modeling fracture in graphene and carbon nanotubes. In addition to fitting the equilibrium material properties, the approach allows fitting the potential to the forcing behavior as well as the mechanical strength of the solid, without requiring ad hoc modification of the nearest-neighbor interactions for avoiding artificial stiffening of the lattice at larger deformation. Consistent with the first-principles results, the potential shows the Young's modulus of graphene to be isotropic under symmetry-preserving and symmetry-breaking deformation conditions. It also shows the Young's modulus of carbon nanotubes to be diameter-dependent under symmetry-breaking loading conditions. The potential addresses the key deficiency of existing empirical potentials in reproducing experimentally observed glass-like brittle fracture in graphene and carbon nanotubes. In simulating the entire deformation process leading to fracture, the SW-potential costs several factors less computational time compared to the state-of-the-art interatomic potentials that enables exploration of the fracture processes in large atomistic systems which are inaccessible otherwise.

RESUMEN

Uterine fibroids often cause symptoms of pelvic pain, pressure, and bleeding and a significant cause of morbidity for women of reproductive age. A new, Food and Drug Administration approved noninvasive treatment option is magnetic resonance guided focused ultrasound surgery, which has the potential to become a treatment of choice for selected patients. The purpose of the study was to compare and evaluate the usefulness of MRI and transabdominal ultrasonography for the diagnosis of uterine fibroids. A cross sectional study was carried out in the department of Radiology & Imaging of Mymensingh Medical College Hospital, during the period of January' 2010 to December 2011. A total number of 40 consecutive patients having suspected uterine fibroids underwent MRI and transabdominal ultrasonography and they were followed up from the admission upto the tissue diagnosis of uterine fibroids for histopathological correlation were included in this study. The test of validity of MRI and transabdominal ultrasonography in diagnosis of uterine fibroids was calculated. In the diagnosis of uterine fibroids, USG was 88.2% sensitive, 66.7% specific, 85.0% accurate, 93.8% positive predictive values and 50% negative predictive values. However MRI was 97.1% sensitive, 83.3% specific, 95.0% accurate, 97.1% positive predictive values and 83.3% negative predictive values for prediction of uterine fibroids. The study shows that the MRI is more efficient diagnostic modality than transabdominal ultrasonography in detecting uterine fibroid presence and evaluation.

RESUMEN

The study was performed to assess the response & side effects of injectable Labetalol in the treatment of pregnancy induced severe hypertension. This interventional study was carried out on 72 patients having pregnancy induced severe hypertension attended in the Department of Obstetrics & Gynaecology, Mymensingh Medical College & Hospital (MMCH), Mymensingh, Bangladesh from November 2009 to October 2010. All patients were treated with intravenous Labetalol 20mg & the dose was repeated at sequential escalating dosages every 15 minutes until a therapeutic goal of systolic blood pressure <160mm of Hg & diastolic blood pressure <105mm of Hg were achieved. Among 72 respondents highest number were observed having systolic blood pressure 160-169 and 180 & above mm of Hg. The mean systolic & the diastolic blood pressure at the initiation of the study were observed 198±13.17mm of Hg & 119±8.6mm of Hg respectively. After use of injection Labetalol mean systolic blood pressure were 138.61±15.43mm of Hg, which is statistically significant (p value <0.001) & mean diastolic blood pressure were 96.18±9.7mm of Hg, which is also statistically significant (p value <0.001). It was observed that majority patients' blood pressure was controlled by 1-2 doses. It was noticed that injection Labetalol controls blood pressure in 80% antenatal cases & 86% postnatal cases. Out of 72 patients 4 cases (5.5%) experienced nausea & vomiting and only 1 case (1.1%) experienced headache. Regarding fetal outcome 48% patients delivered healthy baby, about 31% patients delivered asphyxiated baby & neonatal death were noticed in 4% cases. This study assessing the response & side effects of intravenous antihypertensive drug in the treatment of pregnancy induced severe hypertension shows that Labetalol fulfils the criteria of an antihypertensive drug for this purpose.

RESUMEN

Breast cancer is the most common malignancy in women and the second most common cause of cancer-related mortality. The distinction by physical examination of physiologic nodularity from abnormal masses can be difficult, while the clinical differentiation of a malignant mass from a benign one is difficult; the medical as well as potential legal consequences of missing a palpable carcinoma are high. There are significant number of reported cases of false-negative findings on mammography and the great desire not to miss a malignant lesion in the early stage of disease lead to aggressive biopsy, but the biopsy rate for cancer is only 10.0% to 30.0%. This means that 70.0% to 90.0% of breast biopsies are performed for benign diseases, which induce unnecessary patients discomfort and anxiety in addition to increasing costs to the patient. Clearly, there is a great need for development of additional reliable methods to complement the existing diagnostic procedures to avoid unnecessary biopsy. This cross sectional study was carried out on 43 patients having palpable breast mass, attended in the Department of Radiology and Imaging Mymensingh Medical College Hospital, Mymensingh from 1st January 2012 to 31st December 2013 for the period of two year. These patients were evaluated by USG at the Department of Radiology and Imaging and histopathological examination at the Department of Pathology of the same College to confirm the diagnosis. In diagnosis of malignant mass by USG, 9(20.9%) cases were diagnosed as malignant and 34(79.1%) cases as other than malignant. Eight out of 9 were sonographically diagnosed as malignant lesions also proved as malignant lesion by histopathology and 1 other than malignant. Out of 34 sonographically diagnosed cases of other than malignant lesions 32 were proved histopathologically and 2 did not match with sonographic findings. USG, in diagnosis of malignant lesion, sensitivity was 80.0%, specificity 96.97%, positive predictive value (PPV) (88.89%), negative predictive value 94.12% and accuracy was 93.02% and comparable to other study. In diagnosis of benign lesion by USG, sensitivity was 96.97%, specificity 80.0%, positive predictive value (PPV) (94.12%), negative predictive value 88.89% and accuracy was 93.02%. So, USG is an appropriate imaging method for diagnosis & differential diagnosis of palpable breast mass.

RESUMEN

BACKGROUND: Dentine hypersensitivity is a common problem attributed by patent dentinal tubules. Ingredients incorporated in toothpastes aim to occlude patent dentinal tubules to minimize the dentine hypersensitivity. However, frequent consumption of acidic soft drinks may reverse the dentinal tubules' occlusion. In this in vitro study, the efficacy of dentinal tubules occluded by commercially available toothpastes to withstand different durations of an acidic soft drink challenge was investigated. METHODS: One hundred and twenty dentine discs were divided into three groups. The discs from each group were brushed with toothpaste containing bioactive glass, arginine and control toothpaste. Each group was then divided into four subgroups and exposed to acidic soft drink over four different time durations. RESULTS: The scoring and the percentage of occluded dentinal tubules by Novamin-containing toothpaste was significantly better compared with arginine or the control toothpaste. Acidic soft drink challenge reduced the extent of dentinal tubules occlusion along with time. Dentinal tubules occluded by Novamin-containing toothpaste withstand the acidic challenge comparatively for a longer period. CONCLUSIONS: The findings demonstrated that occlusion of dentinal tubules is more efficient by the bioactive glass-containing toothpaste and thus may contribute to its better resistance to acidic soft drink challenge.

RESUMEN

We describe the treatment of a young girl age, 25 years, with Class II Div1 malocclusion. She presented with an over jet of 12 mm, and the overbite was 10 mm and incomplete. Teeth on upper anterior segment of jaw were proclined and spaced. Teeth on lower jaw were crowded with buccaly placed 1st premolar on right side. Molar relationship was Class II on both sides. Incisior relation was class II div1. Her oral hygiene was good. Treatment consisted mainly of premolars extractions, canine retraction, labeling and alignment with Edgewise fixed appliances by multi loops technique. Once the canine retraction was complete, arch contraction was accomplished with 0.016×0.022 inch closing-loop arch wires followed by finishing with 0.014 inch round wires. The treatment resulted in Class I molar occlusion with proper alignment of both upper and lower anterior segment, an ideal over jet, overbite and incisor angulation.

RESUMEN

A 50-year old, diabetic, hypertensive patient with post-CABG status developed complete loss of vision about one hour after coronary angiogram (CAG). Thorough ophthalmological and neurological examination as well as magnetic resonance imaging of brain especially of the occipital region revealed no abnormality. The patient had complete recovery of vision about 48 hours later. We could not document any specific cause or mechanism for the visual loss, although the selective vulnerability of occipital lobes to contrast agent toxicity (Cortical blindness) was the most likely underlying mechanism.

RESUMEN

Natural convection in a horizontal slot heated from above and from below has been considered. Each heating has a certain spatial distribution. It has been demonstrated that a wide variety of convection patterns can be generated by changing the relative position of both heating patterns. A significant intensification of convection, compared to convection resulting from heating applied at one wall only, results if there is no phase shift between both patterns, while a significant reduction of convection results from the phase shift corresponding to half of the heating wavelength. The system generates a nonzero mean shear stress at each wall for all phase shifts except shifts corresponding to half of and one full heating wavelength. This effect, which is generated within one convection cell, gives rise to a global force which may lead to a thermally induced drift of the walls if such a drift was allowed.

RESUMEN

We describe the treatment of a young girl age, 16 years, with Class I malocclusion. Both upper and lower anterior segment of jaws were crowded with buccally placed canines. Treatment consisted mainly of premolars extractions, canine retraction, labeling and alignment with Edgewise fixed appliances by multiloop technique. The patient did not show good cooperation, hence treatment time was prolonged. However the treatment resulted in Class I molar occlusion with proper alignment of both upper and lower anterior segment, an ideal overjet, overbite and incisor angulation.

RESUMEN

Natural convection in a horizontal layer subject to periodic heating from above has been studied. It is shown that the primary convection leads to the cooling of the bulk of the fluid below the mean temperature of the upper wall. The secondary convection may lead either to longitudinal rolls, transverse rolls, or oblique rolls. The global flow properties (e.g., the average Nusselt number for the primary convection and the critical conditions for the secondary convection) are identical to those of the layer heated from below. However, the flow and temperature patterns exhibit phase shifts in the horizontal directions.

RESUMEN

The mycotoxin sterigmatocystin (STC) is produced mainly by some Aspergillus and Penicillium fungi; it naturally contaminates cereals, peanuts, and products derived from these crops, and is both mutagenic and carcinogenic. As an intermediate of aflatoxin (AF) biosynthesis, its structure is similar to that of AF. Although immunoaffinity columns (IACs) are a popular approach to sample clean-up, no IAC is commercially available for STC, but a commercially available IAC for AF shows cross reactivity to STC. We here developed a new method for analyzing STC in grains using such an IAC and liquid chromatography mass spectrometry (LCMS), and validated this method using six different grains. The STC limit of detection (signal-to-noise ratio, S/N = 3) was 2.5 pg (1.0 µg/kg in the product), and the calibration curve was linear in the range of 7.5-375 pg (3.0-150 µg/kg in the product). The within-day recovery of STC from samples spiked with STC at 5.0 and 50 µg/kg was 83.2-102.5% and the RSDr (relative standard deviation of repeatability) of these samples was 1.9-6.5%; the RSDr of STC-pretreated grain samples was 3.1-14.0%. Average recovery of STC from samples spiked with STC in the range of 5.0-100 µg/kg STC was 83.2-102.5%, with an RSDr of 0.24-6.5%; the RSDr of STC-pretreated grain samples was 2.4-14.0%. In an intermediate precision study, the average STC recovery from STC-spiked samples by three analysts was 95.2-107.5%, with RSDRi (intermediate precision) of 4.0-7.1%; the RSDRi of the STC-pretreated samples was 4.8-10.4%. Thus, the proposed method was effective for STC analysis in grains, and holds potential for a novel application of a commercial IAC, intended for AFs, in STC analysis.

RESUMEN

A significant number of paediatric surgical patients undergone clean surgical procedures. Most of the paediatric surgeon use perioperative prophylactic antibiotic in this clean procedure because of undue fear of infection in their mind. The objective of this study is to evaluate whether the use of perioperative prophylactic antibiotics have an effect to prevent post operative wound infection in clean operation in paediatric surgical patients. This study was conducted in the paediatric surgery department of Bangabandhu Sheikh Mujib Medical University and some private clinics of Dhaka city from January 2009 to December 2009. Two hundred patients who were undergone clean elective surgical procedure on day case basis were included in this study. They were divided into two equal groups (Group A and Group B). The patients of Group A were given intransverse Cephradine 30 minutes before incision and then oral Cephradine was advised postoperatively for 7 days. The patients of Group B were not given any perioperative antibiotic. All the patients of both groups were advised to come on 3rd, 6th and 10th postoperative day for examination of wound. In Group A (With chemo prophylaxis), five patients (5%) developed postoperative wound infection and in Group B (without chemo prophylaxis), three patients (3%) developed postoperative wound infection. Thus the rate of postoperative wound infection is slightly more in patients with chemo prophylaxis but it was not statistically significant by chi-square test. Based on the result of this study, it may be concluded that the antibiotic prophylaxis is not necessary in clean surgery in paediatric age group.

RESUMEN

Congenital bladder diverticula (CBD) are unusual but not rare in childhood. Report of acute urinary retention due to congenital bladder diverticula are rarely found in the literature. Here we report a case of congenital bladder diverticulum with acute urinary retention in a ten months old male infant. Urinary tract infection and urinary retention are the most frequent presentation forms. In this case CBD produce urinary obstruction as a result of compression of the urethra which causes urinary retention. Voiding cystourethrogram revealed a large bladder diverticulum. Bladder diverticulum should be a differential diagnosis in male children, presenting with urinary retention, fever and an abdominal mass. Ultrasonography, voiding cystourethrogram & cystoscopy confirm the diagnosis and diverticulectomy was successfully done for the child.

RESUMEN

Melanotic neuroectodermal tumour in infancy is rare, mainly benign with little tendency to recur after excision or effective curettage. This pigmented neoplasm of neural crest origin occurring in infants before 1 year of age. The most common site of occurrence is the anterior maxillary alveolar ridge (70%), following by the skull, brain and mandible. The genital organ is the most frequent extra cranial site. We report a 6 months old male baby with a similar tumour arising from right half of cheek involving the maxilla. We diagnosed the case after histological report. We remove the tumour through a sub-labial incision. The mass was blackish in colour, and was mobilized from all side including from the maxillary sinuses. The author thought that this should be reported for improving the clinical awareness and treatment of pigmented soft tissue mass in children. Almost one year follow up of the patients showed no recurrence.

RESUMEN

Congenital Muscular Torticollis (CMT) is a postural deformity of head and neck detected at birth or shortly after birth, primarily resulting from unilateral shortening of Sternocleidomastoid Muscle (SCM). In neonates and infants, patient may cure conservatively by physiotherapy but surgery is the treatment of choice for children and adolescents. There are various techniques of surgery. Here we show our experience regarding management of congenital muscular torticollis. In the present retrospective case series, fourteen patients of congenital muscular torticollis were treated. The cases were enrolled between Nov' 2005 to Oct' 2007 in Bangabandhu Sheikh Mujib Medical University, Gonosasthaya Somaj Vittik Medical College Hospital, Dhaka and different private clinics of Dhaka city of Bangladesh. Neonates and infants were treated conservatively with physiotherapy and others treated surgically by transection of both sternal and clavicular head of SCM under general anesthesia. Operated patients were released on following post operative day with advised to do physiotherapy. Patients age range from 7 days to 15 years of which ten were female and four male. SCM was shortened in all cases (8 on right side and 6 on left side). Eleven were female and three male. Of 14 patients, 2 neonates, 7 infants and 5 were more than 1 year age. There was no associated anomaly. Out of 9 neonates and infants 8 cured conservatively with physiotherapy and another one significantly improved. Six were treated surgically including one failed physiotherapy. Post operative period was uneventful and there was no complication. Results were evaluated clinically and comments of peers. Most of the patient of congenital muscular torticollis can be treated conservatively during infancy. Division of both sternal and clavicular head of SCM is easy and safe surgical technique for the treatment of CMT of older children and adolescents.

RESUMEN

A 35-year-old so called snake-expert from Thakurgaon district was admitted in Medicine department of Rangpur Medical College Hospital (RpMCH), Rangpur, Bangladesh on 2nd November 2007 with history of bites by a cobra snake. He was famous for his outstanding works to establish a snake farm first ever in Bangladesh. He had a collection of more than one hundred snakes of different species. He used to hatch eggs of the snakes, feed the young-snakes, collect venoms and sell those. Everyday many visitors used to visit his farm to watch exciting games with poisonous snakes. Several satellite television (TV) channels and some daily newspapers had covered him on different occasions. He was accidentally bitten by a newly caught hungry cobra snake while recording for a satellite TV channel. Following bites he was brought to the hospital three and a half hours later. By that time, neurotoxicity developed. Repeated doses of Anti Snake Venom (ASV) along with respiratory support and other supportive cares were provided. Despite utmost care feasible at RpMCH, patient expired around 49 hours later.

RESUMEN

Strain and nanoscale variations in composition can significantly alter the electronic and optical properties of self-assembled alloy quantum systems. Using a combination of finite element and first-principles methods, we have developed an efficient and accurate technique to study the influence of strain and composition on the quantum confinement behavior in alloy quantum dots. Interestingly, we find that a nonuniform distribution of alloy components can lead to an enhanced confinement potential that allows a large quantum dot to behave electronically in a manner similar to a much smaller dot. The approach presented here provides a general means to quantitatively predict the influence of strain and composition variations on the performance characteristics of various small-scale alloy systems.

RESUMEN

This prospective study was done to evaluate the result of interlocking intramedullary nailing in fracture shaft of the femur under the Department of Orthopaedic Surgery in Mymensingh Medical College Hospital during the period of January 2007 to December 2008. In this study total 66 patients were purposively selected for interlocking nailing initially but 6 patients did not report in subsequent follow up. So, the result of the study was based on 60 patients. There were 38 males and 22 females with the age range of 18 to 70 years, with an average age of 34 years. Motor vehicle accident was the most common cause of the fracture shaft of the femur (60%) and the second most common cause was fall from height (20%). Right sided involvement was more (66.67%). Majority of the patients had fracture lower third of the femur (70%). Among the patients farmer was the most common (33.33%) group and the next was housewife. The mean union time was 17 weeks with the range of 14 to 30 weeks. Postoperative complications were found, such as infection (3.33%) and nonunion (1.66%). The functional outcome of this study was evaluated by Klemm & Borner criteria. Excellent functional outcome was found in 80%, good in 15% and fair in 5%.
