Outcome of Endoscopic Sinus Surgery in the Treatment of Chronic Rhinosinusitis

This prospective study was conducted to compare the outcome of endoscopic sinus surgery (ESS) using SNOT-20 score chart (subjective) and Lund & Kennedy scoring chart (objective) and carried out in the Department of Otolaryngology & Head-Neck Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Dhaka Medical College Hospital (DMCH) & Shaheed Suhrawardy Medical College Hospital (ShSMCH) from July 2010 to March 2012. Total 73 admitted cases were selected purposively for ESS, male 53(72.60%) and female 20(27.40%). Among the study participants 10(13.7%) had chronic rhinosinusitis with bilateral polyposis and 26(35.62%) had chronic rhinosinusitis with unilateral polyposis and 12(16.44%) had bilateral chronic rhinosinusitis without polyposis and 25(34.25%) had unilateral chronic rhinosinusitis without polyposis. Surgical procedures done among the patients were Uncinectomy (infundibulectomy), Middle Meatal Antrostomy; Anterior Ethmoidectomy; Sphenoidotomy, Associated septoplasty and no significant per or post operative complications were noted. In Chronic rhinosinusitis (CRS) with polyposis pre operative SNOT-20 mean and SD 1.322±0.341 and post ESS snot-20 mean and SD 0.3472±0.0755, CRS without polyposis pre operative SNOT-20 mean and SD 0.9297±0.86 and post ESS SNOT-20 mean and SD 1986±0.0558. In CRS with polyposis pre operative Lund & Kennedy score of endoscopic assessment, mean and SD 5.333±2.255 and post ESS mean and SD 1.31±1.009. In CRS without polyposis pre op Lund & Kennedy score mean and SD 3.108±1.074 and post ESS mean and SD 0.76±0.641.Post ESS SNOT-20 in CRS with Polyposis, 't' test result was 27.58 which was significant (p<0.001) and in CRS without Polyposis was 21.622 which was significant (p<0.001); Lund & Kennedy Score of post ESS in CRS with Polyposis 't' test result was 7.763 which was significant (p<0.001), CRS without Polyposis was 7.177 which was significant (p<0.001).This implies that outcome of ESS in treatment of CRS with or without polyposis had statistically significant role. Symptomatic relief and quality of life improvement after ESS was compared by improvement in post operative scores of SNOT-20 & Lund-Kennedy score of endoscopic assessment. Post operative lower values were considered to be better improvement status. The results of the study suggests that ESS performed in Chronic Rhinosinusitis without Polyposis cases, relief of symptoms and quality of life improved was better than Chronic Rhinosinusitis with Polyposis cases postoperatively as compared by SNOT-20 and Lund & Kennedy score of endoscopic assessment.

Prognostic Role of Multiple Cardiac Biomarkers in Newly Diagnosed Acute Coronary Syndrome Patients

Acute coronary syndrome includes unstable angina and myocardial infarction with or without ST-segment elevation, is life-threatening disorders that remain a source of high morbidity and mortality despite advances in treatment. The aim of the study was to evaluate the prognostic role of serum cTnI, CK-MB, hsCRP, MPO and BNP in newly diagnosed acute coronary syndrome patients. This cohort study was carried out in the Department of Biochemistry, Bangabandhu Sheikh Mujib Medical University in cooperation with the Department of Cardiology, BSMMU and NICVD during the period of March 2013 to February 2014. A total 100 newly diagnosed acute coronary syndrome patients were purposively enrolled in this study within 24 hours of attacked, among them 30 were NSTEMI, 65 were STEMI and 5 were unstable angina. Serum cTnI, CK-MB, hsCRP, MPO and BNP concentrations were measured at enrollment and grouping of the study subjects were done on the basis of their empirical cut off values into two groups. In cTnI: Group I (n=20) having cTnI <4ng/ml and Group II (n=80) having cTnI ≥4ng/ml. In CK-MB: Group I (n=18) having CK-MB <10ng/ml and Group II (n= 82) having CK-MB ≥10ng/ml. In hsCRP: Group I (n=36) having hsCRP <5mg/L and Group II (n=64) having hsCRP ≥5mg/L. In MPO: Group I (n=30) having MPO <285.5pmol/L and Group II (n=70) having MPO ≥285.5pmol/L. In BNP: Group I (n=26) having BNP <135pg/ml and Group II (n=74) having BNP ≥135pg/ml. All the study subjects were treated and managed identically by standard management protocol and were followed up periodically up to three months from the onset of events during hospital stay and after discharge. Clinical outcomes of the study subjects such as good recovery, morbidity (recurrent ACS, heart failure, arrhythmia and revascularization) and mortality were evaluated with respect to their base line cTnI, CK-MB, hsCRP, MPO and BNP concentrations. Increased levels of base line cardiac biomarkers in Group II patients showed significantly high morbidity and mortality cTnI (p=0.044), CK-MB (p=0.045), hsCRP (p=0.009), MPO (p=0.003), and BNP (p=0.001) in compared to Group I. In relative risk ratio analysis showed significantly worse outcome in Group II acute coronary syndrome patients in comparison to Group I. In case of cTnI RR - 1.85 at 95% CI 1.19-2.88, in case of CK-MB RR- 1.88 at 95% CI 1.21-2.92, in case of hsCRP RR- 2.05 at 95% CI 1.30-3.25, in case of MPO RR- 2.59, at 95% CI 1.49-4.49, and in case of BNP RR- 3.47 at 95% CI 2.5-5.36. It was concluded from this study that base line serum cTnI, CK-MB, hsCRP, MPO, and BNP can be used clinically as prognostic biomarkers of acute coronary syndrome.

Evaluation of efficiency of nested multiplex allele-specific PCR assay for detection of multidrug resistant tuberculosis directly from sputum samples

For an effective control of tuberculosis, rapid detection of multidrug resistant tuberculosis (MDR-TB) is necessary. Therefore, we developed a modified nested multiplex allele-specific polymerase chain reaction (MAS-PCR) method that enables rapid MDR-TB detection directly from sputum samples. The efficacy of this method was evaluated using 79 sputum samples collected from suspected tuberculosis patients. The performance of nested MAS-PCR method was compared with other MDR-TB detection methods like drug susceptibility testing (DST) and DNA sequencing. As rifampicin (RIF) resistance conforms to MDR-TB in greater than 90% cases, only the presence of RIF-associated mutations in rpoB gene was determined by DNA sequencing and nested MAS-PCR to detect MDR-TB. The concordance between nested MAS-PCR and DNA sequencing results was found to be 96·3%. When compared with DST, the sensitivity and specificity of nested MAS-PCR for RIF-resistance detection were determined to be 92·9 and 100% respectively.

SIGNIFICANCE AND IMPACT OF THE STUDY

For developing- and high-TB burden countries, molecular-based tests have been recommended by the World Health Organization for rapid detection of MDR-TB. The results of this study indicate that, nested MAS-PCR assay might be a practical and relatively cost effective molecular method for rapid detection of MDR-TB from suspected sputum samples in developing countries with resource poor settings.

Hepatic necroinflammation and severe liver fibrosis in patients with chronic hepatitis B with undetectable HBV DNA and persistently normal alanine aminotransferase

Both consensus and controversy remains regarding surrogacy of hepatitis B virus (HBV) deoxyribonucleic acid (DNA) and alanine aminotransferase (ALT), however, these markers are used to ascertain the extent of liver damages and to guide therapeutic options in patients with chronic hepatitis B. However, little is known about liver histology of patients with chronic hepatitis B with undetectable HBV DNA and persistently normal ALT. Thirty-five incidentally-detected patients with chronic HBV infection (assessed by expression of hepatitis B surface antigen for more than 6 months) with undetectable HBV DNA and normal serum ALT were enrolled in this study. Liver biopsy specimens were taken from all patients and the extent of hepatic necroinflammation and liver fibrosis were evaluated. Moderate degree of hepatic necroinflammation was detected in 2 of 35 patients and severe hepatic fibrosis was seen in 6 of 35 patients. Two patients with undetectable HBV DNA and sustained normal ALT had moderate hepatic necroinflammation and severe hepatic fibrosis. In spite of undetectable HBV DNA for prolonged period and persistently normal ALT, some patients with chronic hepatitis B express evidences of progressive liver diseases. Large scale studies in different races and geographical regions should be accomplished to develop insights about management of these patients. Studies about extent of liver diseases in these patients should be accomplished in Treatment recommendation and management strategies should be developed for these patients.

High Quality CdS Thin Film Growth by Avoiding Anomalies in Chemical Bath Deposition for Large Area Thin Film Solar Cell Application

Many high efficiency thin-film solar cells incorporate a thin layer of CdS in the device structure to form a heterojunction. Chemical bath deposition (CBD) is the most preferred method of deposition especially for large area thin film solar cells. This study explored the effects of ammonium sulfate on the CdS film produced by CBD using cadmium sulfate as the cadmium source. The concentration of ammonium sulfate was varied from 0 M up to 0.006 M. The resulting optical, structural and surface morphological properties of the films were characterized. Results have shown that the films obtained at higher concentrations of ammonium sulfate were smoother and the occurrence of pinholes was also reduced. Agglomeration of CdS particles that is usually present in films deposited using cadmium sulfate as a precursor was also noticeably reduced. It was also observed that the rate of deposition also increased, resulting in a thicker film for identical deposition time and temperature. The average thickness of the films produced ranged from 60 nm to 180 nm.

A Comprehensive Study on Mo/CdTe Metal-Semiconductor Interface Deposited by Radio Frequency Magnetron Sputtering

Metal-semiconductor (MS) junction between Mo and CdTe, which is one of the fundamental issues for CdTe based solar cell, has been investigated for films deposited on different substrates. XRD pattern of Mo/CdTe films on the polyimide (PI) substrate shows a strong preferential orientation of MoTe2 in (100) at 2θ = 29.44 degrees, which becomes less apparent as deposition time of CdTe increases. However, on soda lime glass (SLG) no such XRD reflection pattern is observed. Moreover, from EDX measurement, Mo-Te compound also identifies MoTe2 at Mo/CdTe interface on PI substrate, which is not present on SLG. Bulk carrier concentration of Mo/CdTe films on PI substrate for lower deposition time of CdTe is found 1.42 x 10(18) cm(-3), which is almost equal to MoTe2. Thereafter, it decreases as CdTe growth time increases. The type of unintentionally formed MoTe2 on PI substrate is found to be n-type in nature. Lattice constants of a = 6.5 Å for CdTe and a = 3.52 Å for MoTe2 are found from nanostructure study by TEM.

Effect of Sn Doping on the Properties of Nano-Structured ZnO Thin Films Deposited by Co-Sputtering Technique

In this study, tin doped zinc oxide (ZnO:Sn) nano-structured thin films were successfully deposited by co-sputtering of ZnO and Sn on top of glass substrate. The effect of Sn doping on the microstructure, phase, morphology, optical and electrical properties of the films were extensively investigated by means of XRD, EDX, SEM, AFM, Hall Effect measurement, and UV-Vis spectrometry. The results showed that the undoped ZnO film exhibited preferred orientation along the c-axis of the hexagonal wurtzite structure. With increase of Sn doping, the peak position of the (002) plane was shifted to the higher 20 values, and ultimately changed to amorphous structure. The absorption edge was shifted to blue region which confirmed the excitonic quantum confinement effect in the films. Consequently, improved surface morphology with optical bandgap, reduced average particle size, reduced resistivity, enhanced Hall mobility and carrier concentration were observed in the doped films after vacuum annealing. Among all of the as-deposited and annealed ZnO:Sn films investigated in this study, annealed film doped with 8 at.% of Sn concentration exhibited the best properties with a bandgap of 3.84 eV, RMS roughness of 2.51 nm, resistivity of 2.36 ohm-cm, and Hall mobility of 83 cm2 V(-1) s(-1).

Properties of a-SiGe Thin Films on Glass by Co-Sputtering for Photovoltaic Absorber Application

Non-hydrogenated amorphous Silicon-Germanium (a-SiGe) thin films were deposited at two different base pressures by RF magnetron co-sputtering. Moreover, an ex-situ thermal annealing was carried out to investigate the material properties to be suitable as the bottom cell of multi-junction solar cells. Compositional study of the films using EDX showed Ge-rich thin films with 75 atomic% of Ge. XRD reflection study implied that all samples were entirely amorphous in nature. However, a significant improvement of morphology possibly due to low base pressure was observed while thermal annealing caused peening and reduction of surface inhomogeneity in both as-sputtered films. UV-VIS-IR analysis confirmed the FESEM results. The highest transmittance was observed in the as-deposited sample grown at 4 x 10(-5) Torr, which however reduced after thermal annealing. Tauc's model was implied for band gap determination and band gap energy as low as 1.07 eV was found in the annealed sample grown at lower base pressure (4 x 10(-6) Torr). Electrical properties of films were investigated by Hall effect measurement system and results found the reduction of resistivity with the same trend of optical band gap energy.

Carcinoma Tongue--Clinicopathological Presentation

This prospective study was done to observe the diversity of clinical presentation of carcinoma of tongue and to study the pathological variety of carcinoma of tongue and was conducted in the Department of General Surgery and Otolaryngology and Head Neck Surgery in Bangabandhu Sheikh Mujib Medical University, Dhaka Medical College Hospital on 50 patients from January 2011 to July 2013. In this series highest number of patients were middle aged (36%). Male female ratio was 2:1. Average socioeconomic conditions of the patient were poor (68%). Betel nut and leaves chewing (88%) and smoking (56%) habits were commonly practiced for more than 10 years among the patients. Depending on site of involvement, variation in presenting symptoms has been observed. Oral tongue carcinoma mostly was presented with tongue lesion, pain and dysphagia where as the carcinoma of base of tongue commonly was presented with dysphagia, lump in neck. Lateral border of tongue (60%) was seen commonly involved. Ulcerative lesion (56%) predominantly was found in tongue lesion. Eighty percent (80%) of cases had no palpable Lymph node. Only few patients were found with Lymph node metastasis and most of them had carcinoma in base of the tongue (75%). Most of the carcinoma was well differentiated Squamous cell carcinoma. Carcinoma of tongue in our study commonly found in middle aged male patients. Variation of symptoms has depended on anatomical site involved. Most of the carcinoma was well differentiated Squamous cell carcinoma. Carcinoma other than squamous cell was not found.

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%.

Investigation of Pathogenic Escherichia Coli from Diarrheic Calves in Selective Area of Bangladesh

Molecular technique was used to investigate the prevalence of virulent diarrheic genes in pathogenic Escherichia coli and their antibiotic sensitivity patterns. A hundred samples from 100 different diarrheic calves from mid-north-western part of Bangladesh were screened for the presence of virulence factors associated with diarrhea. Following isolation and identification on the basis of cultural, morphological and biochemical properties, the presence of the virulence genes such as eaeA, bfpA, elt, est, stx1 and stx2 were examined using PCR. Antimicrobial susceptibility of 57 E. coli was determined by agar disk diffusion method for 8 antimicrobial agents. Out of 100 samples 57 (57%) were found to be positive for E. coli and their distribution rates according to their age, breed and sex were  66.7% ( 6 days old ), 85.7% (Sahiwal breed) and in  64.2 % (female calves) respectively. Among 57 E. coli isolates, only 16 isolates were analyzed for the detection of the said genes. Among them, only eaeA gene was detected in 2 E. coli isolates (12.5 %). Antibiotic resistance patterns revealed that Oxacillin, Rifampicin and Penicillin were  100% resistant followed by Erythromycin which was more than 80% resistant. In case of Amoxicillin and Tetracycline, about 59.65% and 61.40% were found to be resistant respectively whereas all 57 E. coli isolates showed moderately susceptible (30%) to Cefuroxime, a second generation Cephalosporin. Therefore, none of the eight antimicrobials studied can not be recommended as single best therapeutic agent for the treatment of neonatal calf diarrhea. In addition, this study indicated that diarrhea in calves in these locations can be ascribed to mainly Enteropathogenic E. coli (EPEC) which was atypical (only contained the eaeA genes but not bfpA). However, further studies are necessary to characterize the isolated eaeA gene positive E. coli by serotyping, tissue culture assay and other molecular techniques to find out the potentiality of those virulent genes contributing pathogenicity of E. coli causing diarrhea in calves.DOI: http://dx.doi.org/10.3329/bjvm.v13i1.23716Bangl.

This cross-sectional prospective study was done in the Department of Otolaryngology Head & Neck Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka during the period of January 2008 to December 2009 with the aim to find out the frequency of otitis media with effusion in patients with enlarged adenoid admitted for Adenoidectomy, To see the frequency of otitis media with effusion in different age group, To find out the degree of hearing loss in enlarged Adenoid patients. A total number of 60 patients who were admitted for adenoidectomy with or without tonsillectomy were purposively collected. Male female ratio was 1.6:1. Majority of patients (61.67%) came from lower socioeconomic group. Amongst the patients with enlarged adenoids, OME was found in 32(53.33%) cases. Out of 25 grossly enlarged adenoid cases, OME was found in 19(76%) cases. In 35 cases of moderately enlarge adenoid, OME was found in 13(37.14%) cases. Out of 28 enlarged adenoid cases in age group 0-5 years, OME was present in 19(67.86%) cases and out of 32 enlarge adenoid cases in age group 6-15 years; OME was present in 13(40.62%) cases. Most of the patients presented with multiple clinical features, the commonest was mouth breathing (80%), other features were snoring (58.33%), nasal discharge (56.67%) and hearing impairment (53.33%). In tympanometry, flat curve without peak was found in 25 cases and negative middle ear pressure was seen in 7 cases. Regarding hearing status of patients, 25 cases had a mild to moderate degree of hearing loss and PTA was not done in 7 cases due to lower age group (below 4 years).

Serum LDH and CA-125: Markers for Diagnosis of Ovarian Malignancy

This prospective multi-centre study was carried out in the Department of obstetrics and gynaecology of Bangabandhu Sheikh Mujib Medical University, Dhaka Medical College Hospital and Bangladesh Medical College Hospital, Shaheed Suhrawardy Medical College Hospital, Dhaka, Bangladesh, during the period of January 2008 to December 2009, to establish the raised level of serum LDH and serum CA-125 in pre-operative discrimination of benign and malignant ovarian cancer to be used as a diagnostic marker and its validity by determining sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPP). A total number of 141 consecutive suspected subjects of ovarian tumour admitted in the above mentioned hospitals and enrolled for surgical management were included in this study. Serum LDH was done in all these subjects and they were followed up from the admission upto the postoperative tissue diagnosis of live tumor in respective pathology departments for histopathological correlation. The patients who were diagnosed as malignant placed in Group I and diagnosed benign ovarian tumor placed in Group II. Serous cystadenoma and mucinous cyst adenoma were more common in benign tumors, which were 38.9% and 20.4% respectively. However, more than a half (57.1%) had serous cyst adenocarcinoma in malignant tumors. In LDH for evaluation of malignancy, true positive 16 and false positive 18, false negative 12 and true negative 95 cases. LDH and serum CA-125 level (combined, i.e. both positive) for evaluation of malignancy, true positive 14 and false positive 0, false negative 14 and true negative 113 cases. LDH/serum CA-125 level (anyone positive) for evaluation of malignancy, true positive 25 and false positive 37, false negative 3 and true negative 76 cases. The validity of LDH were sensitivity 57.1%, specificity 84.1%, accuracy 78.7%, positive predictive values 47.1% and negative predictive values 88.8% for malignancy of ovarian tumour. The validity of CA-125 were sensitivity 78.6%, specificity 82.3%, accuracy 81.6%, positive predictive values 52.4% and negative predictive values 93.9% for malignancy of ovarian tumour. The validity of LDH and serum CA-125 level (combined, i.e. both positive) for malignant ovarian tumour it was found that sensitivity 50.0%, specificity 100.0%, accuracy 90.1%, positive predictive values 100.0% and negative predictive values 89.0%.

Comparative study of early and conventional catheter removal following buccal mucosal graft urethroplasty

The duration of catheterization period following urethroplasty is a great controversy. For buccal mucosal graft urethroplasty recommended catheterization period ranges from 2-4 weeks. In recent years, early catheter removal has been advocated for several reasons. Early catheter removal improves both patient comfort, mobility and reduces catheter related complications and shortens post operative hospital stay. This prospective observational study was done from January 2007 and December 2008, 50 patients underwent dorsal onlay buccal mucosal graft urethroplasty for stricture urethra. Among them 25 cases were selected for early catheter removal on 7th postoperative day and 25 cases for conventional catheter removal at 3 weeks. Three patients (12%) of early catheter removal group and 2 patients (8%) of conventional catheter removal group exhibited periurethral leakage. One patient (4%) and three patients (12%) developed wound infection in early and conventional catheter removal group respectively. No significant difference was observed in urinary flow (p=0.089). In these two groups the mean postoperative hospital stay was significant (p<0.001). Early catheter removal on 7th postoperative day is safe and has better impact on patient comfort with minimum catheter related complications and shortens hospital stay.

Parotid gland metastasis - an unusual presentation of adenocarcinoma of lung

Lung cancer is the most frequent malignant disease and the most common cause of cancer death in the world. Primary carcinoma of the lung was an uncommon cancer until the 1930s. Common cell types in bronchial carcinoma are squamous 35%, Adenocarcinoma 30%, Small-cell 20%, Large-cell 15%. We present a case of a bronchial neoplasm metastasis to the parotid gland. A 50 years old male patient presented with a 7×5cm painless parotid mass that was metastatic adenocarcinoma on histopathology. Then we thoroughly examined the patient and he was investigated accordingly. There was an abnormal shadow in the lung on chest x-ray, CT revealed a lung tumour on left side. Metastasis to the parotid gland from any distant primary site is quite unusual. We are going to present this case in the journal because of its rarity. Parotid gland metastasis from the lung is rare & if a careful examination is not performed primary focus may be overlooked, negatively affecting the lifetime survival rate & the prognosis of the patient.

In-patient diabetes care: the impact of diabetes outreach team on long-term glycaemic control

AIM

Our aim is to assess the impact of inpatient diabetes services on glycaemic control in patient with diabetes admitted to a secondary care hospital in UK.

METHODS

We performed a retrospective analysis of all diabetes mellitus (DM) in-patients who were seen by our Diabetes Outreach Team from June 2007 to December 2010. Those with an admission diagnosis of hypoglycaemia were excluded. Blood samples including HbA1c at the initial visit and subsequent outpatient follow-up at 3-6 months were collected. Patients admitted with newly diagnosed diabetes were analysed separately.

RESULTS

In total 2002 patient data were captured. 778 patients were eliminated initially because of failure to attend follow-up clinic, lack of follow-up HbA1c data, and because of planned discharge to the community. Complete blood samples were available for 1224 patients. Of this, 235 patients (19.2% of those with complete data) were analysed separately as their primary diagnosis was hypoglycaemia. In the remaining 989 patients, 31 (3.1%) new onset Type 1 DM patients and 91 (9.2%) new onset Type 2 patients were analysed separately. In patients with known DM (n = 867) HbA1c improved from 75 mmol/mol (9.0% ± 2.39) to 69 mmol/mol (8.46% ± 2.0) (p < 0.001). In the newly diagnosed Type 1 DM (n = 31) patients HbA1c improved from 114 mmol/mol (12.55% ± 2.27) to 58 mmol/mol (7.43% ± 2.05) (p < 0.001). In the newly diagnosed Type 2 DM (n = 91) patients HbA1c improved from 93 mmol/mol (10.70% ± 3.04) to 56 mol/mol (7.29% ± 1.74) (p < 0.001). In those who presented with hypoglycaemia (n = 235) HbA1c changed from 58 mmol/mol (7.48% ± 1.59) to 59 mmol/mol (7.59% ± 1.57) (p = 0.2).

CONCLUSION

By providing a comprehensive care, structured education and appropriate intervention through our Diabetes Outreach Team, we have shown a significant reduction in HbA1c for recently hospitalised patients.

A case of acute insulin poisoning with attempt to suicide

A 18 years old girl with no known comorbidities was admitted in female medicine ward through the emergency department with rapid onset of semi consciousness due to hypoglycaemia (plasma glucose in admission was 2.0mmol/L). She had history of self-injection of insulin (regular insulin 300 units) subcutaneously in abdominal wall. However she didn't developed serious complications of hypoglycaemia and was subsequently discharged after conservative treatment.

QTL analysis in multiple sorghum populations facilitates the dissection of the genetic and physiological control of tillering

A QTL model for the genetic control of tillering in sorghum is proposed, presenting new opportunities for sorghum breeders to select germplasm with tillering characteristics appropriate for their target environments. Tillering in sorghum can be associated with either the carbon supply-demand (S/D) balance of the plant or an intrinsic propensity to tiller (PTT). Knowledge of the genetic control of tillering could assist breeders in selecting germplasm with tillering characteristics appropriate for their target environments. The aims of this study were to identify QTL for tillering and component traits associated with the S/D balance or PTT, to develop a framework model for the genetic control of tillering in sorghum. Four mapping populations were grown in a number of experiments in south east Queensland, Australia. The QTL analysis suggested that the contribution of traits associated with either the S/D balance or PTT to the genotypic differences in tillering differed among populations. Thirty-four tillering QTL were identified across the populations, of which 15 were novel to this study. Additionally, half of the tillering QTL co-located with QTL for component traits. A comparison of tillering QTL and candidate gene locations identified numerous coincident QTL and gene locations across populations, including the identification of common non-synonymous SNPs in the parental genotypes of two mapping populations in a sorghum homologue of MAX1, a gene involved in the control of tiller bud outgrowth through the production of strigolactones. Combined with a framework for crop physiological processes that underpin genotypic differences in tillering, the co-location of QTL for tillering and component traits and candidate genes allowed the development of a framework QTL model for the genetic control of tillering in sorghum.

Photo-anthropometric study on face among Garo adult females of Bangladesh

Facial anthropometry has well-known implications in health-related fields. Measurement of human face is used in identification of person in Forensic medicine, Plastic surgery, Orthodontics, Archeology, Hair-style design and examination of the differences between races and ethnicities. Facial anthropometry provides an indication of the variations in facial shape in a specified population. Bangladesh harbours many cultures and people of different races because of the colonial rules of the past regimes. Standards based on ethnic or racial data are desirable because these standards reflect the potentially different patterns of craniofacial growth resulting from racial, ethnic and sexual differences. In the above context, the present study was attempted to establish ethnic specific anthropometric data for the Christian Garo adult females of Bangladesh. The study was an observational, cross-sectional and primarily descriptive in nature with some analytical components and it was carried out with a total number of 100 Christian Garo adult females aged between 25-45 years. Three vertical facial dimensions such as facial height from 'trichion' to 'gnathion', nasal length and total vermilion height were measured by photographic method. Though these measurements were taken by photographic method but they were converted into actual size using one of the physically measured variables between two angles of the mouth (chilion to chilion). The data were then statistically analyzed by computation to find out its normatic value. The study also observed the possible 'correlation' between the facial height from 'trichion' to 'gnathion' with nasal length and total vermilion height. Multiplication factors were estimated for estimating facial height from nasal length and total vermilion height. Comparison were made between 'estimated' values with the 'measured' values by using't' test. The mean (+/- SD) of nasal length and total vermilion height were 4.53 +/- 0.36 cm and 1.63 +/- 0.23 cm respectively and the mean (+/- SD) of facial height from 'trichion' to 'gnathion' was 16.88 +/- 1.11 cm. Nasal length and total vermilion height showed also a significant positive correlation with facial height from 'trichion' to 'gnathion'. No significant difference was found between the 'measured' and 'estimated' facial height from 'trichion' to 'gnathion' for nasal length and total vermilion height.

Cirrhosis of liver and portal vein thrombosis - a review article

Cirrhosis is characterized by diffuse hepatic fibrosis and nodule formation which can occur at any age with significant morbidity and is an important cause of premature death. Occlusive portal vein thrombosis (PVT) is common complication of chronic liver disease with prevalence ranging from 1% to 16% of population. The occurrence of portal vein thrombosis is influenced by local factors (cirrhosis with associated liver architectural changes and increased resistance effects), systemic factors (inherited and acquired abnormalities leading to hyper coagulability) and development of hepatocellular carcinoma. The majority of patients with cirrhosis PVT are diagnosed on radiographic studies although in some patients PVT may present with decompensated chronic liver disease but the natural history of PVT in patients with cirrhosis is largely unknown. However patients with cirrhosis and PVT have been shown to have inferior survival in comparison with patients without PVT.

Detection of Giardia lamblia and Cryptosporidium parvum by direct immunofluorescence assay in stool specimen

Giardia and Cryptosporidium are the pathogens which transmitted through contaminated soil and contaminated water are significant causes of diarrhea and nutritional disorders in institutional and community peoples. Children and immune compromise persons are more vulnerable for these infections. Both Giardiasis and Cryptosporidiosis were included in 2004 as WHO Neglected Disease. So this is a major public health problem in developing countries. The present study was carried out to detect the Giardia and Cryptosporidium from diarrheic or patient having loose stool by Direct Immunofluorescence assay. The study was conducted during July 20012 to February 2013 and the work was done in Mymensingh Medical College in the department of Microbiology and in Bangladesh Agricultural University in the department of Veterinary Medicine. A total of 100 loose stools were collected from school children of different area and hospital under sadar upazilla, Mymensingh. The detection of Giardia lamblia and Cryptosporidium parvum showed the individual prevalence 8% and 4% respectively. The highest cyst/oocyst count was 85,000 and 1,000/gm of stool and the lowest being 100 and 50/gm of stool for Giardiasis and Cryptosporidiosis respectively. The detection rate of Giardia and Cryptosporidium by Immunofluorescence assay was relatively higher than the previous study done in Bangladesh and this was the first report from Bangladesh over human stool specimen using Immunofluorescence assay. So, Immunofluorescence assay could be adapted for rapid and accurate detection of Giardia and Cryptosporidium.

Association between elevated B-type Natriuretic Peptide levels with extent of coronary artery disease in patients with unstable angina and NSTEMI

The study was undertaken to find out the correlation of elevated B-type Natriuretic Peptide (BNP) levels with the severity of coronary artery disease in patients with unstable angina and NSTEMI. This cross sectional analytical study was carried out in the department of cardiology, National Institute of Cardiovascular Diseases, Dhaka during a period of August 2011 to June 2012. A total of 100 consecutive patients with unstable angina and NSTEMI undergoing coronary angiography were included in the study. BNP assay was done by Architect system, a chemo luminescent microparticle immunoassay (CMIA). CAG was done by conventional method within 14 days of index hospital admission. Study patients were divided into two groups on the basis of BNP levels. In Group I, BNP Levels were ≤80pg/ml and in Group II, BNP levels were elevated >80pg/ml. with 50 patients in each group. Angiographic severity of CAD was assessed by vessel score and Friesinger score. Vessel score showed single vessel was involved in 21(47.7%) patients while multi vessel in 23(52.3%) patients was found in Group I. On the contrary 11(22.4%) single vessel patients and 38(77.6%) multivessel patients were found in Group II. There was significant association between vessel involvement (p=0.01). Friesinger score revealed that less severe CAD was found in 22(44%) patients and significant severe CAD in 28(56.0%) patients in Group I. On the contrary 7(14.0%) less severe CAD patients and 43(86.0%) severe CAD patients were found in Group II. There was significant difference between severity of CAD among the study groups (p=0.01). There was linear correlation between BNP pg/ml and coronary artery disease severity in terms of Vessel score (r=0.38, p=0.01) and Friesinger score (r=0.51, p=0.01). The present study concluded that increased BNP level >80pg/ml was significantly associated with the presence and severity of CAD in patient with UA and NSTEMI.

Isolation and identification of diarrheagenic Escherichia coli causing colibacillosis in calf in selective areas of Bangladesh

This study was carried out to isolate, identify and characterize Escherichia coli from diarrheic calves, their prevalence and antibiotic sensitivity pattern during the period from November 2011 to December 2012. For this purpose 100 diarrheic fecal samples were collected from four different areas of Bangladesh. The samples were aseptically collected and brought to the laboratory of Medicine, Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh. The organisms were identified as E. coli on the basis of cultural, morphological and biochemical characteristics. Further the isolated bacteria were confirmed by amplification of E. coli specific 16sRNA gene. The antibiotic resistant pattern of the isolates was also performed. Out of 100 samples 49 (49%) were found to be positive for E. coli. The highest prevalence was found in Shahjadpur, Sirajganj (53.33%) while lowest was in BAU, Mymensingh (40%). The antibiogram study revealed that all isolates were resistant against ampicillin, erythromycin, azithromycin and streptomycin where erythromycin was 100% resistant, whereas 100% sensitivity was found to tetracycline and gentamicin which might be the best choice of drug for the treatment of diarrheagenic E. coli causing colibacillosis in calves.DOI: http://dx.doi.org/10.3329/bjvm.v11i2.19139Bangl.
