Mucinous Adenocarcinoma of the Appendix: A Case Report.

Primary tumors of the appendix are unusual and most of them are carcinoids. Their main presentation is that of an acute appendicitis or as a palpable mass, mainly in the right lower quadrant. A 40 years old male patient presented in Dhaka Community Medical College Hospital, Dhaka, Bangladesh on 31st October 2013 with mucous adenocarcinoma of the appendix, which primarily presented as heaviness in right lower abdomen and atypical abdominal pain. Diagnosis of the disease was made after right hemicolectomy and histopathological analysis of the specimen. Mucin producing adenocarcinomas of the appendix are a category of rare cancers of the gastrointestinal tract. Although at present they are a well studied pathological entity, the crucial issue of their preoperative diagnosis remains unsolved.

An Evaluation of Faculty Wise Teaching Performance in a Public Medical College of Bangladesh.

Teaching is a complex and demanding activity that involves Mastery of content, classroom control and techniques of organization and command of teaching skills. Teachers' continuous engagement in learning, skill acquisition and refinement to practice is essential for meeting student learning needs. Medical education is principally centered on the transmission of medical knowledge and assisting medical students to acquire the necessary skills and attitudes associated with medical practice. Evaluation of teaching is important in the teaching-learning process. The medical profession demands to be increasingly concerned with evaluation of teachers' performance as a part of its accountability. This study was designed to evaluate teaching performance in the department of Pharmacology, Forensic Medicine, Microbiology, Community Medicine and Pathology in Mymensingh Medical College and this descriptive cross sectional study was conducted among 94 students of 5th year MBBS students (session 2011-2012) of Mymensingh Medical College, Bangladesh from January 2016 to June 2016. A semi-structured self-administered questionnaire was used for collection of data. All the respondents provided opinion regarding scholarship of teachers, methods of presentation, communication and interaction, learning, coverage of contents and approachability by a 5 points rating scale. Attained score was variable in the context of different statements and different faculties. Students were also asked to provide suggestions for improvement of teachers' performance in each subject. Remarkable number of the students demanded for deployment of subject-specific teachers in adequate number. A significant number of students called for more practical classes in Pathology, Microbiology and Pharmacology. They also desired for the improvement of teaching quality and student friendly attitude from the teachers. A significant number of students opined that teaching materials and other logistics in the class rooms and even the class rooms were inadequate and need improvement in this regards. Regular conduction of classes by adequate number of teachers having post-graduate degree in the relevant faculty with adequate skill in teaching, student-friendly attitude of the teachers, adequate physical facilities and teaching materials help in improvement of teaching quality.

Quality of Life in Children with Asthma in Bangladesh.

Asthma is a public health problem that adversely affects different aspects of quality of life. Childhood asthma is common in Bangladesh affecting their lifestyle. The objective of the study was to assess health-related quality of life in children with bronchial asthma. A descriptive, cross-sectional study was carried out from January 2014 to December 2014 at the Outpatient Department of National Asthma Centre, Mohakhali, Dhaka among hundred sixty-two purposively selected children of both sexes with bronchial asthma aged from 7 to 17 years. Data were collected through interview with children or their parents using an interviewer-administered questionnaire based on Pediatric Asthma Quality of Life Questionnaire (PAQLQ). Data were analyzed by computer software SPSS version 16.0. The mean age was 12.5 years with a standard deviation (SD) of 2.9 years. Overwhelming majority 157(96.9%) of children were literate, while only 5(3.1%) children were illiterate. Eighty (49.4%) children were male, while 82(50.6%) female. As many as 148(91.4%) children were students, while 10(6.2%) children were engaged in some type of job and 4(2.5%) children had no occupation. Parents of 145(89.5%) children were currently married, while 10(6.2%) children had single parent and 7(4.3%) children's parents were divorced or separated. Quality of life in children with asthma decreases with age as the disease intensity increases with age. Female asthmatic children had lower overall score of Quality of life (p=0.017), as well as lower activity domain score (p<0.001). Emotional domain score was found lower in children with single parent (p=0.021) and low monthly family income (p<0.001). Furthermore, children with lower monthly family income and working children had lower Quality of life score in all domains.

A Retrospective Histopathological Study on Extra-pulmonary Tuberculosis in Mymensingh.

Tuberculosis is a very common disease in our country. This retrospective histopathological study was designed to assess the distribution of extra-pulmonary tuberculosis (EPTB) in various organs through examination of biopsy specimens. A total of 216 specimens were diagnosed as tubercular lesion by histopathological evaluation in the Department of pathology, Community Based Medical College and a private laboratory during the period from January 2014 to December 2014. Mean age of the case was 32 years. Majority of the cases were female (126 out of 216). Lymph nodes were the most common site of EPTB (62.96%) followed by skin and subcutaneous tissue (17.59%), intestine (11.11%), breast (2.77%), female genital tract (2.31%), male genital tract (1.38%), bone and joint (1.85%). Out of 136 cases of tubercular lymphadenitis, 96(70.58%) were cervical, 18(13.23%) were axillary, 12(3.82%) were mesenteric and 10(7.35%) were inguinal. This study reveals, in our locality, EPTB is very common in adulthood with female preponderance. Cervical lymph node is very common sites for EPTB.

Mapping QTLs for drought tolerance in an F2:3 population from an inter-specific cross between Gossypium tomentosum and Gossypium hirsutum.

Cotton is one of the most important natural fiber crops in the world. Its growth and yield is greatly limited by drought. A quantitative trait locus (QTL) analysis was therefore conducted to investigate the genetic basis of drought tolerance in cotton (Gossypium spp) using 188 F2:3 lines developed from an inter-specific cross between a wild cotton species, G. tomentosum, and an upland cotton, G. hirsutum (CRI-12). A genetic map was constructed using 1295 simple sequence repeat markers, which amplified 1342 loci, distributed on 26 chromosomes, covering 3328.24 cM. A field experiment was conducted in two consecutive years (2014 and 2015) and 11 morphological and physiological traits were recorded under water-limited (W1)/well-watered (W2) regimes at three growth stages (bud, flowering, and full boll). The traits measured included chlorophyll content, plant height, leaf area, leaf number, leaf fresh weight, leaf dry weight, boll weight, number of bolls per plant, and the number of fruiting branches. Sixty-seven and 35 QTLs were found under the W1 and W2 conditions, respectively. Of these, the majority exhibited partial dominance or over-dominance genetic effects for increasing the trait values. Four consistent QTLs were found under the W1 treatment on chromosomes 5, 8, 9, and 16, whereas no consistent QTL was found in W2. Thirteen QTL clusters were also identified on nine chromosomes (2, 3, 5, 6, 9, 14, 15, 16, and 21). These results will help to elucidate the genetic basis of drought tolerance in cotton.

The Castleman's Disease and Related Disorders--A Case Report.

Castleman's disease is a rare primary disease of the lymph nodes. Little is known about the management of the disease. Surgical treatment gives a very good result. What other modalities of treatment could be done is not yet established. The role of surgery gives good result and follow up evaluation is satisfactory. We found a solitary intra-abdominal mass of lymphoid hyperplasia with a histological diagnosis of Castlemans disease identified in the pathological data base. Unicentric disease was defined as it was a solitary mass. Clinical, Radiological and Laboratory data were analysed to evaluate treatment response. The patient also has related disorders as Acanthosis nigricans, Myoneuronal disorder as-MG and bronchiolitis. The patient diagnosed as angiofollicular hyperplasia (Castleman's disease). After evaluation patient under went surgical treatment, partial excision of tumor mass due to morbid adhesion with inferior vena cava. The patient becomes symptom free and lump disappears within 60 days of treatment. There was no recurrence of the disease after further evaluation. The author recommends that in Unicentric variant of Castlemans disease surgical resection of the tumor is curative. The unicentric tumour may be hyaline-vascular or hyaline-vascular/ plasma cell type. Partial resection, Radiotherapy or observation alone may avoid excessive aggressive therapy.

Comparing the Performance Status Scale and MD Anderson Dysphagia Inventory as swallowing outcome measures in head and neck cancer: a prospective cohort study.

OBJECTIVES: To examine the relationship between the two disease-specific measures currently in use to assess swallowing outcomes following treatment in patients with head and neck cancer: the Performance Status Scale (PSS) and MD Anderson Dysphagia Inventory (MDADI). DESIGN: A prospective cohort study. SETTING: Four head and neck cancer multidisciplinary clinics in the North of England Cancer Network. PARTICIPANTS: 114 patients with cancers of the upper aerodigestive tract. MAIN OUTCOME MEASURE: Measures of swallowing function administered prospectively across 4 timepoints RESULTS: Spearman's correlation coefficients were used to measure the relationship between the two scales. There was statistically significant correlation between the two tools at pre-treatment (rs = 0.428, P < 0.000), 3 months post-treatment (rs = 0.454, P < 0.002), 6 months post-treatment (rs = 0.551, P < 0.000) and 12 months post-treatment (rs = 0.680, P < 0.000). CONCLUSION: This is the first prospective study comparing the MDADI and PSS questionnaires at multiple time points. Our study shows that these different instruments have a good relationship in measuring swallowing function in patients with head and neck cancer in short and medium term after treatment.

Variations of Weight of Thyroid Gland in Different Age and Sex Groups of Bangladeshi Cadavers.

A cross sectional descriptive study was designed to find out the difference in weight of the thyroid gland of Bangladeshi people in relation to age and sex. The present study was performed on 70 post mortem human thyroid gland (35 of male and 35 of female) collected from the morgue in the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh by purposive sampling technique. The specimens were collected from Bangladeshi cadavers of age ranging from 10 years to 85 years. All the specimens were grouped into three categories Group A (upto 20 years), Group B (21 to 50 years) and Group C (>50 years) according to age. Dissection was performed according to standard autopsy techniques. The weight of the thyroid glands were measured and recorded. The mean weight of the thyroid gland was 6.94 ± 5.20 gm in Group A, 7.91 ± 5.89 gm in Group B and 10.42 ± 6.27 gm in Group C. The mean weight of the thyroid gland in male was 7.0 ± 5.77 gm in Group A, 9.94 ± 7.63 gm in Group B and 11.89 ± 5.73 gm in Group C and in female was 6.88 ± 4.88 gm in Group A, 5.88 ± 2.15 gm in Group B and 9.10 ± 6.74 gm in Group C. Variance analysis shows that there was no significant difference in mean weight between the Age Group A & B, B & C and C & A. There was significant difference of weight of thyroid gland between sex in age Group B but in Group A and Group C were statistically insignificant. The weight of the thyroid gland was found to increases with age. In statistical analysis, differences between age groups were analyzed by using one way ANOVA test. The present study will help to increase the information pool on the weight of thyroid gland of Bangladeshi people.

Spectrum of Salivary Gland Lesions in a Tertiary Level Hospital.

Salivary gland tumors are relatively infrequent and account for less than 2% of all human tumors. This study was conducted to see the prevalence of patterns of non neoplastic and neoplastic lesions of salivary glands in greater Mymensingh. It was a retrospective study carried out in the department of Pathology, Community Based Medical College Bangladesh from January 2010 to December 2012. Heamatoxylin and eosin stained sections were studied in all cases. Total 98 cases of salivary gland lesions were retrieved and evaluated. Out of them 55 cases were female and 43 were male. Mean age of the cases were 42 years. Among the salivary gland lesions non-neoplastic lesions 24.48% and neoplastic lesions 75.51%. Among neoplastic lesions benign tumor comprises 91.89% and malignant tumor comprises 8.10%.

Women's Overall Satisfaction with Childbirth Experience in a Tertiary Level Hospital of Bangladesh.

Women's satisfaction with care in labour is a positive indicator for the woman herself, as well as healthcare organization as a whole. This study was aimed to find out the women's satisfaction with their childbirth. It also tried to identify significant differences across various mode of delivery and satisfaction related to women's childbirth experience. It was a descriptive type of cross-sectional study conducted among 278 post-natal mother who give live birth at government tertiary hospital namely Mymensingh Medical College Hospital, Bangladesh. The study was conducted in the department of Obstetrics and Gynaecology during the period of January 2020 to December 2020. Data were collected from the respondents by face to face interview using a self-administered semi-structured questionnaire including Salmon's Item List. Level of overall satisfaction with childbirth was assessed by Salomon's Item List. Data analysis was carried out by SPSS version 25.0. The dimension of physical discomfort, emotional distress and fulfilment had a Cronbach's alpha of 0.746, 0.966 and 0.982 respectively. The internal consistency of each dimension was found to be acceptable and reliable. The mean scores of the dimensions in Salmon's Item List for Fulfilment, Emotional distress and Physical discomfort was found to be 69.20, 50.85 and 50.40 respectively. Higher total scores indicate a more positive evaluation of the childbirth experience and lower scores indicate a more negative evaluation. In this study the Overall mean scores of the three dimensions was 50.75. The mean scores of 'fulfillment' was higher in normal vaginal delivery (NVD) and scores of both "emotional distress" and "physical discomfort" were higher in lower uterine cesarean section (LUCS). Among all the three dimensions, mean scores of 'fulfillment' was higher in NVD indicating more satisfaction with NVD than LUCS and instrumental delivery. On the other hand, scores of "physical discomfort" and "emotional distress" were lower in NVD indicating less satisfaction with NVD than LUCS.

The role of diffusion-weighted MRI in the accurate diagnosis of vertebral compression fractures: A comparative study.

INTRODUCTION: Accurately distinguishing between benign and malignant vertebral compression fractures is crucial for clinical management. This study evaluated the predictive accuracy of diffusion-weighted imaging (DWI) in differentiating the cause of vertebral fractures using MRI. METHODS: A longitudinal cross-over study was conducted at Jinnah Postgraduate Medical Centre (JPMC) Karachi from July 2018 to January 2021. Patients with vertebral compression fractures underwent T1-weighted, T2-weighted, and DWI imaging with ADC mapping on a 1.5 T MRI scanner. Imaging findings were compared with histopathologic results and clinical follow-up. Sensitivity, specificity, and ROC curve analyses were performed. RESULTS: The study enrolled 303 patients with a mean age of 43.6 ± 10.9 years, of whom 118 were male. DWI demonstrated high accuracy in predicting the cause of vertebral compression fractures, with a sensitivity of 96.2 %, a specificity of 76.2 %, and an area under the ROC curve of 0.857. The optimal ADC cut-off value was 0.82 × 10˄-3 mm˄2/s, which yielded a positive predictive value of 79.7 % and a negative predictive value of 95.4 %. CONCLUSIONS: DWI is a safe and non-invasive imaging modality with excellent predictive accuracy in differentiating between benign and malignant vertebral compression fractures. Iso- or hypointensity of collapsed vertebral bodies on DWI suggests a benign lesion, while T2-weighted hyperintensity is highly indicative of malignancy. Low signal on ADC is also highly indicative of malignant vertebral fractures. Incorporating DWI improves accuracy in assessing vertebral lesions, especially when standard sequences are inconclusive. IMPLICATIONS FOR PRACTICE: DWI revolutionizes vertebral compression fracture diagnosis, distinguishing between benign and malignant cases. This precision guides treatment decisions, minimizing the necessity for invasive procedures like biopsy. As a safe and reliable imaging method, DWI elevates patient care, ensuring accurate diagnostics and improved outcomes.

Study of Serum Electrolytes (Sodium and Potassium) Abnormalities in Acute Stroke.

Stroke is the common cause of death and disability worldwide, as well as in Bangladesh. Serum electrolytes abnormalities or dyselectrolytaemia is one of the major acute complications of stroke. Dyselectrolytaemia or serum electrolytes (sodium and potassium) abnormalities are more common in patients with acute stroke that can be easily measured. The study was planned to find out the serum electrolytes (sodium and potassium) abnormalities in acute stroke patients. This cross-sectional study was conducted in the Department of Neurology and Medicine, Mymensingh Medical College and Hospital from January 2019 to June 2020. Total 84 purposively selected patients with acute strokes were evaluated following informed written consent. Diagnosis was confirmed by neuroimaging of brain. Moreover, serum electrolytes level was measured for each patient. Data were collected by interviews, clinical examinations & laboratory investigations of the patients using a case record form and analysis was carried out by the help of SPSS 25.0. Mean age of the patients with acute strokes were 57.65±15.79 years. About two thirds (60.7%) of the patients were male and the remaining (39.3%) were female. Sodium imbalances were observed in 32.2% and potassium imbalances in 25.0% cases. About 66.7% haemorrhagic strokes patients and 42.2% ischaemic strokes patients had dyselectrolytaemia (p<0.05). More than twenty eight percent (28.6%) of all stroke patients had hyponatraemia, which was more common (35.9%) among haemorrhagic strokes patients (p<0.05). Of all stroke patients 21.4% had hypokalaemia, which was more common (28.2%) in haemorrhagic strokes patients (p<0.05). This study reveals that, serum electrolytes (sodium and potassium) abnormalities are more common in haemorrhagic than ischaemic strokes, which is mainly hyponatraemia and hypokalaemia.

Structural, thermodynamic, and magnetic properties of SrFe12O19 hexaferrite modified by co-substitution of Cu and Gd.

A hard magnetic system of SrFe12O19 nanomaterial was modified according to the composition of Sr0.95Gd0.05Fe12-xCuxO19 with x = 0.0, 0.30, and 0.60 using the sol-gel technique. The structures of the samples were evaluated using X-ray diffraction (XRD) along with Rietveld refinement, and an M-type hexaferrite with a hexagonal structure was confirmed with a trace amount of the α-Fe2O3 phase. In addition, transmission electron microscopy (TEM) analysis revealed polycrystalline nanoplates in all samples. Furthermore, the bond structures of the octahedral and tetrahedral sites along with the thermodynamic properties of these ferrites were extracted from the FTIR spectra at room temperature. The Debye temperature (θD) decreased from 755.9 K to 749.3 K due to the co-substitution of Gd3+ at Sr2+ and Cu2+ at Fe3+. The magnetic hysteresis (M-H) measurements revealed that the coercivity decreased from 5.3 kOe to 1.5 kOe along with the highest magnetization saturation (Ms) of 65.2 emu g-1 for the composition Sr0.95Gd0.05Fe11.7Cu0.3O19, which is suitable for industrial application. The effect of local crystalline anisotropy in magnetization was explored using the law of approach to saturation (LAS). Finally, thermo-magnetization was recorded in the range from 400 K to 5 K for cooling under zero field and in the presence of a 100 Oe field, and magnetic transitions were tracked due to the introduction of the foreign atoms of Gd and Cu into SrFe12O19.

Domestic Violence against the Female Garment Workers in Selected Area of Bangladesh.

The Impact of Hypertension, Coronary Heart Diseases and Diabetes on COVID-19 Illness.

This study tried to understand the impact that hypertension, coronary heart diseases and diabetes can have on the intensity of coronavirus within the human body. This study was conducted using a systematic review process where secondary data have been collected from 10 previously published research papers. Most of the individuals contracting COVID-19 are also suffering from diabetes, cardiovascular diseases and hypertension. The studies used to carry out this systematic review have exhibited a pattern that indicates a strong correlation. That being said, because of the possibility of extraneous variables, most of the studies at this point have significant drawbacks. Many of such variables for example, smoking behavior or level of fitness have not been considered while selecting sample for most of the studies. Therefore, more highly targeted studies need to be carried out for understanding this disease and the long- and short-term impact it can have.

Phase wise evaluation of teachers by the students in Mymensingh Medical College, Bangladesh.

Students' evaluations of teachers are used to ensure quality in medical education and as a tool for faculty development. Teacher evaluation is also one of the performance measurements of the Annual Performance Agreement (APA). The objective of this research was to evaluate teachers of four phases of MBBS program by the students of corresponding phase. This cross sectional descriptive type of observational study was conducted in Mymensingh Medical College (MMC), Bangladesh during the period of January 2023 to March 2023. A total of 40 purposively selected teachers engaged in either lecture, tutorial or clinical bedside classes were evaluated by 469 randomly selected students using a self-response evaluation form provided by Centre for Medical Education (CME) which contains 16 statements of 5 points: 1=Never, 2=Once in a while, 3=Sometimes, 4=Most of the time and 5=Almost always. Data were analyzed in SPSS, version 22.0. Ten (10) teachers from each phase were included in the study. Among the students 169(36.0%) were from phase I followed by each 100(21.3%) from phase II, III and IV. Out of 80, total mean score of phase I was 64.11±9.187. Total mean score of phase II was 72.08±7.520 and that of phase III was 72.19±6.510. Highest total mean score (76.95±5.032) was found in phase IV. Overall mean score of teachers of MMC irrespective of phase was 70.27±9.017. Mean scores of teachers in individual statement of phase I, II, III and IV were 4.02±0.847, 4.49±0.706, 4.51±0.614 and 4.81±0.482 respectively. Mean scores in individual statement of every phase were between "Most of the time (4)" and "Almost always (5)" indicating positive performance of evaluated teachers. All of the 40 teachers had a median score of more than 4 in the explicit issues indicating that most of the students agreed that the teachers taught their core subjects well. They had a median score of more than 4 in the implicit issues too which indicated that the students felt that all of the teachers gave importance to the core values. Moreover, 21(52.5%) teachers had a median score of 5 in both explicit and implicit issues indicating highly positive performance of those evaluated teachers. Teachers of Mymensingh Medical College performed admirably across all phases. This type of feedback evaluation should be applied throughout every institute as it will help faculty members enhance their abilities and academic performance, leading to overall faculty development. As a result, quality of medical education will be ensured.

It is a severely distressing experience for many couples and it may significantly affect the physical and mental life of infertile individuals. The study was to assess the level of mental health state (depression, anxiety and stress) among the infertile women in tertiary level hospital in Bangladesh. This cross sectional descriptive study was conducted at two tertiary level hospitals in Bangladesh named BSMMU and CARe Medical College. Three hundred and fifty-two (352) infertile women were taken as a sample and a semi-structured questionnaire which contains question with related variables and DASS 21 was used. The study results revealed that, the mean age of the respondents was 29.32 years. Almost three-fourth 260(73.86%) of the respondents were Muslim and 349(99.14%) respondents were educated. Two-third 223(63.35%) of the respondents were from rural area and 177(50%) were housewife. About 229(65.05%) were live in a joint family and 205(58.23%) had an abortion history. Majority 312(88.63%) of the respondents had monthly income BDT <30000 Taka. According to DASS 21, 175(49.71%) had depression, 212(60.22%) had anxiety and 157(44.60%) suffered from stress. There was a significant association (p<0.05) found between mental health state with age, religion, residence and occupation. This finding reinforces the need of attention counseling and others advance psychological interventions for positive impact on outcome during treatment of this group of women.

Exploration of the structural, vibrational, electronic, mechanical and thermal properties of Ru4Al3B2 and Ru9Al3B8: a DFT study.

The structural, dynamical, electro-optical, mechanical, and thermal characteristics of the newly synthesized intermetallic compounds Ru4Al3B2 and Ru9Al3B8 have been studied under ambient and elevated pressure through density functional theory (DFT). The obtained lattice parameters of the compounds are consistent with the experimental values. The metallic character of these compounds is established by the band structure and density of states (DOS). The electronic charge density distribution and bond analysis imply that Ru4Al3B2 and Ru9Al3B8 have mainly both ionic and covalent bonding. The non-negative phonon dispersion frequency of the compounds reaffirms their dynamical stability. Both compounds are tough as well as have high melting points, and hence, can be applied in harsh conditions. Mechanical properties are significantly improved under pressure. Thermal barrier coating (TBC) is a possible field of application for both compounds. The different thermal properties such as the Debye temperature (ΘD), Grüneisen parameter (γ), melting temperature (Tm), minimum thermal conductivity (Kmin) and lattice thermal conductivity (κph) of these compounds have been studied to figure out the suitable application areas in thermally demanding situations. The pressure and temperature dependent bulk modulus (B) and other thermodynamic properties have also been analyzed, which suggested that the present compounds are strong candidates for device applications at high temperature and pressure. Owing to their high optical absorptivity and reflectivity in the UV region, they are also candidates for UV-based applications. Furthermore, they also have applicability in the fields of electronics, aviation, energy storage, and supercapacitor devices for their superior electronic, thermal and mechanical properties.
