Abstract
Anaplasma marginale is the most prevalent tick-borne haemoparasite of cattle and causes huge economic losses to the dairy industry worldwide. This study aimed to determine the occurrence of A. marginale infection in blood and tick samples collected from livestock animals in the districts located in Khyber Pakhtunkhwa (KPK), Pakistan. A total of 184 blood and 370 tick samples were included in this study. It has never been reported that sheep, goats, and cattle in Tank, Ghulam Khan, Birmil and Miran Shah areas were infected with A. marginale. All samples of blood and ticks were collected through random sampling from March 2021 to January 2022 from cattle, sheep and goats and screened through PCR for anaplasmosis by using primer pairs of Anaplasma spp. Three hundred and seventy ticks were collected from infested hosts (120/184, 64.21%). Among the four morphologically identified tick species, the highest occurrence was recorded for Rhipicephalus sanguineus (n=138, 37.29%), followed by Rhipicephalus microplus (n=131, 35.4%), Rhipicephalus annulatus (n=40, 10.81%), Hyalomma anatolicum (n=31, 8.37%), and Hyalomma marginatum (n=30, 8.1%). The occurrence of female tick was highest (n=160, 43.24%), followed by nymphs (n=140, 37.38%) and males ticks (n=70, 18.9%). Among these ticks, A. marginale was detected in female ticks of R. microplus, and R. sanguineus. Molecular identification of A. marginale was confirmed in 120 out of 184 blood samples and 6 out of 74 tick samples. Overall, occurrence of A. marginale in blood and tick samples was found to be 65.21% and 8.1% respectively. Species-wise occurrence in blood samples of goats were 71.11% followed by sheep 68.31% and cattle 50%. Specie-wise occurrence of A. marginale in tick samples of cattle were 12.5% followed by goats 6.89%. The obtained sequence showed similarity with A. marginale reported from Kenya and USA. We report the first PCR based detection of A. marginale infection in blood samples and in R. sanguineus ticks of goats simultaneously.

Abstract
Cystic endometrial hyperplasia (CEH)-pyometra (CEH-P) is one of the most common reproductive disorders in bitches, posing a risk to both future fertility and life. The aims of the current study were to elucidate the differential expression patterns of inflammatory mediators at transcript and protein levels in the endometrium and to assess the concentrations of key inflammatory mediators in the peripheral circulation of bitches with different graded CEH-P. A total of 25 client-owned intact mixed breed bitches of 3-10 years presented to the outpatient department of RVP-TVCC of the institute were considered for the study. Of which, 22 cases suggestive of pyometra and 3 cases of CEH obtained during routine elective ovariohysterectomy were subjected to histopathological examination. Uteri were categorized into CEH (n = 3), moderate CEH-P (mCEH-P, n = 9), severe CEH-P (sCEH-P, n = 6) and atrophic pyometra (AT-P, n = 7). A group of age matched (n = 12) bitches without pyometra served as control. Endometrial transcripts such as IL6, IL8, PTGS2, PGFS, and SLPI were expressed differentially in the CEH and CEH-P bitch. In addition, a strong immunoreactivity (IR) of IL6, IL8, PTGS2, and mPGES1 was recorded in the sCEH-P uterus, while expression of IL10 was noticed in AT-P. In circulation, serum IL6 was the most relevant marker with high sensitivity of 96.2% and specificity of 84.6% at a cut off concentration 8.5 pg/mL followed by SLPI with 95.2% sensitivity, and 84.6% specificity at cut off concentration of 1.3 ng/mL. Serum IL10, PGFM and SLPI concentration in the peripheral circulation were 1.5-2.23 fold higher in mCEH-P, 0.87-2.5 fold higher in sCEH-P and 2.9-3.5 fold higher in AT-P than that of control. It is concluded that monitoring the serum concentration of IL6, IL10 and SLPI would be useful adjunct to the established hematobiochemical parameters in the management of pyometra in the bitch with critical illness.

Abstract
Biocides, including disinfectants and antiseptics, are used for a variety of topical and hard surface applications in health care facilities. Biocides play a significant role for preventing and controlling nosocomial infections. However, failures in the antimicrobial activities of biocides have been reported. The resistance mechanism to disinfectants is usually determined by genes which are related to resistance to quaternary ammonium compounds, namely, qacE, qacΔE1 that are found in Gram-negative bacteria. The aim of this study is to detect the prevalence of Biocides resistance genes, qacE and qacΔE1, in clinical isolates of Pseudomonas spp. It was carried out from March 2017 to July 2018 in the department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh. Samples were collected from Outpatient of ENT department, MMCH. In this study, 300 clinical samples of CSOM cases were tested by the PCR method. The present study shows detection of biocide resistance genes (qacE, qacΔE1) among 87 isolated Pseudomonas spp by uniplex PCR. Among 72 clinical isolates of Pseudomonas aeruginosa 67(93.05%) had the gene qacEΔ1 and 25(34.72%) had the gene qacE. In addition other 15 Pseudomonas spp 3(20%) isolates had the qacEΔ1 gene and 2(13.33%) isolates had the qacE gene. In this study there is a marked difference in detection of the qacEΔ1 gene between the MDR and non MDR P. aeruginosa isolates. The qacEΔ1 was identified in 50 of 54(92.59%) MDR isolates and 7 of 18(38.89%) non MDR strains respectively. While gene qacE was detect 25(46.29%) MDR isolates and did not show any qacEΔ1gene in non MDR isolates. This study shows that the genes, qacE, qacΔE1 are widespread among Pseudomonas aeruginosa, they are higher in MDR strains than non MDR strains.

Abstract
Alpha amylase, catalyzing the hydrolysis of starch is a ubiquitous enzyme with tremendous industrial applications. A 1698 bp gene coding for 565 amino acid amylase was PCR amplified from Geobacillus thermodenitrificans DSM-465, cloned in pET21a (+) plasmid, expressed in BL21 (DE3) strain of E. coli and characterized. The recombinant enzyme exhibited molecular weight of 63 kDa, optimum pH 8, optimum temperature 70°C, and KM value of 157.7µM. On pilot scale, the purified enzyme efficiently removed up to 95% starch from the cotton fabric indicating its desizing ability at high temperature. 3D model of enzyme built by Raptor-X and validated by Ramachandran plot appeared as a monomer having 31% α-helices, 15% β-sheets, and 52% loops. Docking studies have shown the best binding affinity of enzyme with amylopectin (∆G -10.59). According to our results, Asp 232, Glu274, Arg448, Glu385, Asp34, Asn276, and Arg175 constitute the potential active site of enzyme.

Abstract
L-Asparaginase catalysing the breakdown of L-Asparagine to L-Aspartate and ammonia is an enzyme of therapeutic importance in the treatment of cancer, especially the lymphomas and leukaemia. The present study describes the recombinant production, properties and anticancer potential of enzyme from a hyperthermophilic archaeon Pyrococcus abyssi. There are two genes coding for asparaginase in the genome of this organism. A 918 bp gene encoding 305 amino acids was PCR amplified and cloned in BL21 (DE3) strain of E. coli using pET28a (+) plasmid. The production of recombinant enzyme was induced under 0.5mM IPTG, purified by selective heat denaturation and ion exchange chromatography. Purified enzyme was analyzed for kinetics, in silico structure and anticancer properties. The recombinant enzyme has shown a molecular weight of 33 kDa, specific activity of 1175 U/mg, KM value 2.05mM, optimum temperature and pH 80°C and 8 respectively. No detectable enzyme activity found when L-Glutamine was used as the substrate. In silico studies have shown that the enzyme exists as a homodimer having Arg11, Ala87, Thr110, His112, Gln142, Leu172, and Lys232 being the putative active site residues. The free energy change calculated by molecular docking studies of enzyme and substrate was found as ∆G - 4.5 kJ/mole indicating the affinity of enzyme with the substrate. IC50 values of 5U/mL to 7.5U/mL were determined for FB, caco2 cells and HepG2 cells. A calculated amount of enzyme (5U/mL) exhibited 78% to 55% growth inhibition of caco2 and HepG2 cells. In conclusion, the recombinant enzyme produced and characterized in the present study offers a good candidate for the treatment of cancer. The procedures adopted in the present study can be prolonged for in vivo studies.

Abstract
Oral submucous fibrosis (OSF) is a chronic complex potentially pre-malignant condition caused by chewing areca nut and other irritants. It is an insidious process characterized by Juxta-epithelial deposition of fibrous tissue in the oral cavity and pharynx. OSF is very common in Southeast Asia and also now a days increase in Europe and North America. The aim of this study to compare the effectiveness of intralesional injection of triamcinolone and hyalurunidase versus intralesional injection of triamcinolone plus injection hyalurunidase with oral colchicine. The study included 60 patients of clinically diagnosed case of oral submucous fibrosis. Patients were divided into two Groups A and B. Group A patients received combination intralesionsl injection of triamcinolone acetonide 10mg/ml in 1ml with injection hyalurunidase 1500IU in 2ml with injection 2% lidocaine 7ml. 15 days interval in 3 months and Group B received intralesional injection of triamcinolone acetonide 10mg/ml in 1ml with injection hyalurunidase 1500IU in 2ml with injection 2% lidocaine 7ml in each 15 days interval for 3 months with oral colchicine 0.5mg twice daily for 3 months. Diagnosis based on burning sensation of mouth, blanching of mucosa, ulceration in oral cavity and also reduced mouth opening. Follow up assessment was done at intervals 1st follow up on 21st days after starting of treatment then 2nd follow up after 3 months and last 3rd follow up after 6 months. Before starting of treatment all patients were properly explained about the study and took their written consent. Much more improvement occurred in Group B patients, reducing in burning sensation and also increases in opening of mouth. In both groups blanching mucosae were improved. Treatment regimen of Group B is more effective in increasing mouth opening and improves burning sensation of oral cavity. No side effects were seen in both groups' patients.

Abstract
This prospective study was conducted at Department of ENT, Mymensingh Medical College Hospital, a tertiary care center in Bangladesh January 2017 to December 2018 to report hearing results and post operative complications of cartilage interposition ossiculoplasty in one-stage intact canal wall (ICW) tympanoplasty for cholesteatoma where ossicular chain is eroded or has to be removed either partially or totally. Total 42 patients underwent Intact canal wall (ICW) tympanoplasty for cholesteatoma with at least intact stapes footplate and in conjunction, cartilage ossiculoplasty was done during the same procedure. Patients were followed up regularly at 1 week, 1 month, 3 month, 6 month and at 1 year as usual follow up protocol to note complications and hearing status in 1 year follow up. In intact stapes suprastructure group, in the preoperative period, the mean air conduction thresholds (AC), bone conduction threshold (BC) and air-bone gap (ABG) were 48.3db, 9.5db and 38.8db respectively. Postoperatively, with a mean follow-up of 12 months, AC, BC and ABG were 27.6db, 9.7db and 17.9db respectively. In missing stapes supra structuregroup, in the preoperative period, the mean air conduction thresholds (AC), Bone conduction threshold (BC) and air-bone gap (ABG) were 57.4db 13.5db and 43.9db respectively. Postoperatively, with a mean follow-up of 12 months, AC, BC and ABG, were 33.9db, 14.2db and 19.7db respectively. For management of cholesteatoma cases, cartilage ossiculoplasty can be done effectively in conjunction with of intact canal wall tympanoplasty in a single setting. Complications are a few and easily manageable. Hearing results are at least as good as with other prosthesis and helps in avoiding subsequent surgery, discomfort and cost to the patients.

Abstract
Purpose Pleural infections are associated with significant inflammation, long hospitalizations, frequent comorbidities, and are often treated operatively—all of which are consequential risk factors for thrombo-embolic complications. However, their occurrence following the treatment of pleural infection is still unknown. The aim of the study was to ascertain the early and long-term occurrence of thrombo-embolic events in patients treated for pleural infections. Methods The study included all patients that were treated for pleural infections in Tampere University Hospital between January 2000 and December 2016. Data regarding later treatment episodes due to pulmonary embolisms and/or deep vein thromboses as well as survival data were requested from national registries. The rates were also compared to a demographically matched reference population adjusted for age, sex, and the location of residence. Results The final study population comprised 536 patients and 5318 controls (median age 60, 78% men). The most common etiology for pleural infection was pneumonia (73%) and 85% underwent surgical treatment for pleural infection. The occurrence of thrombo-embolic complications in patients and controls was 3.8% vs 0.1% at three months, 5.0% vs 0.4% at one year, 8.8% vs 1.0% at three years, and 12.4% vs 1.8% at five years, respectively, p < 0.001 each. Female sex, advanced age, chronic lung disease, immunosuppression, video-assisted surgery, and non-pneumonic etiology were associated with a higher incidence of thrombo-embolism. Conclusions The occurrence of thrombo-embolic events—particularly pulmonary embolism but also deep vein thrombosis—was significant in patients treated for pleural infections, both initially and during long-term follow-up.

Abstract
Chronic suppurative otitis media (CSOM) is a notorious infection in developing countries causing serious local damage and threatening complications. It was a cross sectional observational study to isolate and identify aerobic bacteria and to analyze the susceptibility pattern of the aerobic bacterial isolates. It was carried out from March 2017 to July 2018 in the department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh. Samples were collected from Outpatient of ENT department, MMCH. Out of a total 300 patients with CSOM were enrolled in this study and 209 were culture positive. Among them gram negative organisms were 129(61.72%) and gram positive organisms were 70(33.49%). The most frequently isolated organism in this study was Pseudomonas aeruginosa 72(34.44%), gram positive organisms S. aureus 63(30.14%), E. coli 21(10.04%), other Pseudomonas spp (other than P. aeruginosa) 15(7.17%), mixed bacterial infectios 10(4.78%), Proteus spp 9(4.30%), CoNS 7(3.34%), Klebsiela lspp 7(3.34%), Acinetobactor spp 5(2.39%). P. aeruginosa isolates had least resistant to imipenem and colistin, S. aureus were showed high sensitivity to Vancomycin and Linezolid and E. coli were sensitive to imipenem and amikacin, ciprofloxacin and amikacin respectively. Pseudomonas aeruginosa was the most common bacteria isolated from chronic discharging ears followed by Staphylococcus aureus. Piperacillin-Tazobactum, Ciprofioxacin, Gentamicin and Amikacin were found to be the most suitable drug for Pseudomonas aeruginosa, S. aureus and E. coli. The resistance against ceftriaxone and aztreonam was found to be very high.

Abstract
Aims To evaluate the diagnostic abilities of near-infrared light transillumination (using the DIAGNOcam) and bitewing radiographs in detecting cavitated proximal carious lesions in primary molars. Subjects and Methods The study was a cross-sectional analytical, clinical study. The proximal surfaces of primary molars of healthy 5- to 8-year-old children were radiographically screened for the presence of carious lesions in the enamel or outer third of dentin (D1). Two trained and calibrated examiners evaluated the depth of caries in bitewing radiographs and DIAGNOcam images and then verified the presence of cavitation by direct visual examination using the "International Caries Detection and Assessment System" after temporary tooth separation. Results A total of 236 proximal lesions were included in the study. Most of the clinically cavitated lesions (51.9%) were D1 radiographically and in outer dentin lesions (scores 3 and 4) by the DIAGNOcam (37% and 48.1%, respectively). Although DIAGNOcam showed higher sensitivity (0.852) compared to the radiographs (0.519), it showed slightly less specificity (0.569) compared to the radiographs (0.579). However, DIAGNOcam showed higher value of the area under the curve (AUC = 0.722; P < 0.001) compared to the radiographic method (AUC = 0.561; P = 0.308). Conclusions The DIAGNOcam showed higher sensitivity and better accuracy than bitewing radiographs in diagnosing cavitated proximal lesions in primary molars and can be generally considered as an alternative to radiographs to detect cavitation without the hazards of ionizing radiation in children.

Abstract
Background Femoral-shaft fractures are among the most common fractures of the lower extremity in children. There are several different options for treating femoral-shaft fractures in children. Elastic stable intramedullary nailing (ESIN) has become the standard treatment for fractures of shaft of femur in children for reasons including mini-invasive surgery, no need for casting, early mobilization and discharge as well as growing concerns toward cost-effectiveness. Objective To demonstrate the effectiveness of intramedullary fixation of fracture shaft of femur in skeletally immature children using the titanium elastic intramedullary nails. Method Forty children who underwent fixation with titanium intramedullary nails because of fracture of shaft of femur (Winquist and Hansen type 1 and 2) were reviewed. There were 60% male and 40% female patients and mean follow-up was six months. Time of union, deformity at fracture site, limb length discrepancy, knee range of motion and complications were assessed. Result Average age of the patients was 5.17 years (range 3 to 10). All patients achieved complete healing at a mean 12.8 weeks (range 10 to 20 weeks). Average limb length discrepancy was -0.16 cm (range -1.0 to 1.1 cm) average knee range of motion was 137.55 degrees (range 118 to 152 degrees). Complications were recorded in 13 (31.7%) patients and included: Five malunion which did not show any deformity or functional impairment and eight superficial wound infections which were healed after removal of nail. All patients were active as their pre injury levels at six months follow up. Conclusion Elastic stable intramedullary nailing is the method of choice for the simple pediatrics fracture shaft of femur, as it is minimally invasive and shows good functional and cosmetic results. It allows short hospital stay and quick recovery from pain and is cast-free.

Abstract
BACKGROUND AND AIMS The development of pleural infection may imply a worse state of health and prognosis. The objective of this study was to ascertain the long-term survival and causes of death after pleural infections and to compare them to those of matched controls. MATERIAL AND METHODS Altogether 191 patients treated for pleural infections at a single University Hospital between January 2000 and December 2008 and 1910 age- and gender-matched controls were included. Survival data and the causes of death for non-survivors were obtained from national databases and compared between the groups. RESULTS The etiology of pleural infection was pulmonary infection in 70%, procedural complication in 9%, trauma in 5%, malignancy in 4%, other in 7%, and unknown in 5% of patients. The course of treatment was surgical in 82%, drainage only in 12%, and conservative in 5% of included patients. The median follow-up time was 11 years. Mortality rates were 8.4% versus 0.8% during the first 90 days, p < 0.001, and 46.6% versus 24.5% overall, p < 0.001, in patients and controls, respectively. Mortality was significantly higher in patients with pulmonary infection, procedural complication, or malignancy as the etiology of pleural infection. In multivariable analysis, advanced age, previous malignancies, institutional care, alcoholism, and malignant etiology for the infection were associated with inferior survival. Deaths caused by malignancies, respiratory diseases, and digestive diseases were significantly more common in patients than in controls. CONCLUSION Long-term survival in patients with pleural infections is significantly inferior to that of age and gender-matched controls.

Abstract
BACKGROUND AND AIMS To describe the incidence of and risk factors for postoperative infections and the correlation between postoperative hyperglycemia despite tight blood glucose control with infectious and other complications after contemporary cardiac surgery. MATERIAL AND METHODS The study comprised 1356 consecutive adult patients who underwent cardiac surgery between January 2013 and December 2014 and were followed up for 6 months. Patients surviving the first 2 days were included in the analysis. Preoperative demographic information, medical history, procedural details, and the postoperative course were recorded. The target range for blood glucose levels was 4-7 mmol/L and repeated arterial blood samples were obtained during the intensive care unit stay. The associations of blood glucose levels during the first postoperative day and the occurrence of postoperative infections and other significant complications were analyzed. RESULTS Of the study cohort, 9.8% developed infectious complications which were classified as major surgical site infections in 2.2%, minor surgical site infections in 1.1%, lung infections in 2.0%, unclear fever or bacteremia in 0.3%, cannula or catheter related in 2.6%, multiple in 1.5%, and other in 0.2%. The incidence of deep sternal wound infection was 2.0%. Repeated hyperglycemia occurred in 39.7% of patients and was associated with increased rates of postoperative infections, 12.1% versus 8.2%, p = 0.019; stroke, 4.9% versus 1.5%, p < 0.001; and mortality, 6.1% versus 2.1%, p < 0.001, when compared to patients with single or no hyperglycemia. CONCLUSION Every 10th patient develops infectious complications after cardiac surgery. Repeated hyperglycemia is associated with increased rates of infectious complications, stroke, and mortality.

Abstract
The present study was conducted to evaluate the antioxidant activity of ethanol, n-hexane, dichloromethane, ethyl acetate and water extracts of four different Pleurotus spps. P. ostreatus, P. sajor-caju, P. sapidus and P. columbinus. The extraction was performed by classical organic solvent extraction (COSE). The extracts of Pleurotus spps. contained appreciable levels of total phenolic contents (TPC) (0.95-19.49 GAE, mg/g) and total flavonoid contents (0.85-3.73 CE, mg/g). All Pleurotus spps. also contained considerable DPPH radical scavenging activity, showing IC50 (19.15-54.50%) and reducing power (0.50-2.94 nm), respectively. The ascorbic acid content was in the range of (2.90-5.97 mg/g) for all Pleurotus spps. All studied Pleurotus spps. showed potential antioxidant activity. The results of four different Pleurotus spps. extracts showed that they can be used as a good food ingredient, and as a medicinal mushroom for digestive ailments, as well as in the pharmaceutical industry and in cosmetics.

Abstract
Introduction: Distal tibial fractures present as a major challenge for the orthopedic trauma surgeons. Most non-operative treatments result in non-union or malunion and needs prolonged immobilization of the knee and ankle joints, with resulting stiffness. Open reduction and internal fixation as well as external fixation has high rate of infection and non-union. Minimally Invasive Plate Osteosynthesis has been shown to have a better outcome and has been the procedure of choice in most distal tibial fractures since the introduction of the locking compression plate. The objective of the study is to review the outcome of Minimally Invasive Percutaneous Osteosynthesis (MIPO) in unstable distal tibial fractures.Methods: Charts of patients who underwent MIPO from the year 2008 to 2013 for unstable distal tibial fractures over five years at Patan Hospital and Om Hospital were reviewed. All displaced closed fractures and Gustillo Anderson Type I and II fractures were included in the study. Plates consisted of the anatomically contoured 4.5 mm LCP and 3.5 mm LCP-Pilon form plate. A simple uniplanar external fixator was used to retain the reduction till the plate was inserted and secured with locking screws. The outcome of MIPO in distal tibial fractures were followed up and evaluated. Clinical and radiological assessments were performed at 6 weeks, and at 3, 6, 9, 12 and 24 months.Results: Of the 75 patients (45 male, 30 female) age ranging from 19 to 70 years (mean 47 years), 5 patients were lost to follow-up. 28 patients at 3 months, 32 at 6 months, and 8 at 9 months met the criteria for a healed fracture. Two patients required autologous bone grafting at 9 months for non-union ultimately resulting in the fracture union at 16 months. There was one malunion attributable to the loss of reduction during plate fixation. There were no deep infections, no soft tissue complications and no failures of fixation. The cause of fracture were RTA (n=35), fall from height (n=9), twisting of ankle as a result of fall from standing height (n=22), and others (n=11). The mean time for surgery from the time of injury was 5 (range, 2 to 14) days; the mean hospital stay was 10 (range, 7 to 21) days.Conclusion: MIPO is an effective treatment for closed, unstable fractures of the distal tibia, avoiding the complications associated with more traditional methods of internal fixation and/or external fixation.Journal of Society of Surgeons of NepalVol. 17, No. 2, 2014, Page: 7-11

Abstract
BACKGROUND Tobacco dependence has been defined as a chronic relapsing disease. Around 5 million annual tobacco-related deaths have been reported worldwide. The majority of smokers want to quit but are not successful. OBJECTIVES To screen our population for tobacco use, gauge the baseline demographics of tobacco users and assess factors associated with failed attempts to quit. METHODS Free health camps supervised by a physician were held across two major cities of Pakistan. All consenting participants were administered a questionnaire and had their exhaled carbon monoxide (CO) levels measured. RESULTS Of 12 969 participants successfully enrolled, the mean age was 31.4 ± 10.0 years. More than three quarters were aged 20-40 years (n = 10 168, 78.4%). The overall average CO level was 12.0 ± 8.0 ppm. The majority of the participants wanted to quit, and nearly everyone had received advice about quitting. The majority had tried smoking cessation pharmacotherapy. Friends/peer pressure (n = 1554, 12%), anxiety (n = 681, 5.3%), tobacco dependence (n = 1965, 15.2%) and stress/mood changes (n = 390, 3.0%) were the most widely observed reasons for failure to quit in study participants. CONCLUSION The information provided by this study can guide the development of more targeted intervention programmes for smokers who wish to quit.

Abstract
Aflatoxins are secondary metabolites produced by Aspergillus spp. which are injurious to animals and humans The aim of this study was to determine the effects of aflatoxin B1 (AFB1) on Average Daily Feed Intake (ADFI), Average Daily Weight Gain (ADWG), haematological and serum biochemical responses of Bovine Calves and to determine the comparative efficacy of two different liver tonics against AFB1. Twenty seven calves were selected from herd and divided into 3 groups. All calves were fed with 1.0 mg/kg AFB1 for a period of 10 days. After that they were fed with liver tonics: Silymarin fed at a rate of 600 mg/kg and Choline chloride 500 mg/kg for 7 days. The results indicate that the ADFI and ADWG of AFB1 treated calves decreased significantly. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN) and creatinine significantly increased due to AFB1. In haematology the total erythrocyte count (TEC), total leukocyte count (TLC), haemoglobin concentration (HGB), haematocrit levels (HCT), mean corpuscular haemoglobin (MCH), mean corpuscular volume (MCV) and mean corpuscular haemoglobin concentration (MCHC), lymphocyte %, neutrophil % and monocyte % significantly decreased in AFB1 treated calves after 10 days of feeding. Both liver tonics significantly (p<0.05) improved all the parameters, including ADFI, ADWG, hematologial and serum biochemical test. However, Silymarin comparatively more efficiently ameliorate the effects induced by AFB1 than choline chloride.

Abstract
BACKGROUND The aim was to compare the long-term outcomes of percutaneous transluminal angioplasty (PTA), a supervised exercise programme (SEP) and combined treatment (PTA + SEP) in patients with intermittent claudication owing to femoropopliteal disease. METHODS Patients recruited to an RCT comparing these treatments were invited for long-term follow-up from 2010 to 2011. Indicators of limb ischaemia were recorded (ankle : brachial pressure index (ABPI) and treadmill walking distances). Duplex ultrasound imaging was also done. Patients completed Short Form 36 and VascuQol quality-of-life (QoL) questionnaires. RESULTS Of 178 patients initially recruited to the trial, 139 were alive at the time of follow-up (PTA 46, SEP 47, PTA + SEP 46). Assessments were completed for 111 patients. Median time to follow-up was 5·2 (i.q.r. 3·8-7·4) years. Sixty-nine patients (62·2 per cent) were symptomatic; 18 (16·2 per cent) had experienced a major cardiovascular event since their last follow-up visit. Improvement was observed in ABPI in all groups. QoL outcomes were inconsistent across individual groups. PTA and PTA + SEP groups had a significantly higher ABPI than the SEP group. No significant difference was observed in treadmill walking distances, QoL outcomes, restenosis rates, and new ipsilateral and contralateral lesions on duplex imaging. Patients in all groups required reinterventions (PTA 14, SEP 10, PTA + SEP 6). The total number of reinterventions was higher after PTA (29) compared with SEP (17) and PTA + SEP (9), but failed to reach statistical significance. CONCLUSION PTA, SEP and combined treatment were equally effective long-term treatment options for patients with claudication owing to femoropopliteal disease. The addition of a SEP to PTA can reduce the rate of symptomatic restenosis and reintervention. Registration number: NCT00798850 (http://www.clinicaltrials.gov).

Abstract
Chronic respiratory diseases (CRD) like asthma and chronic obstructive pulmonary disease (COPD) are one of the leading causes of morbidity and mortality worldwide. A patient's perception, about his or her medicine, may have an impact on adherence to medications. The purpose was to assess the attitudes and perceptions, regarding inhaler therapy use, among patients with obstructive pulmonary disease in Pakistan, a developing country. With a questionnaire developing this cross-sectional study was conducted at the Department of Medicine's outpatient clinic at Civil Hospital, Karachi from October 2013 to January 2014. We used SPSS version 19 for data entry. The number of patients included in the study was 202. Fifty eight percent (58%) of the patients concurred that they were not compliant with the usage of inhalers and frequently missed their doses. Thirty three percent (33%) patients had the misconception that inhalers are prescribed for severe diseases only. Almost forty percent (40%) patients said that they would prefer oral medicines over inhalers for the management of their lung diseases. Sixteen percent (16%) of the patients had problems using their inhalers. Twenty six percent (26%) of the patients believed that inhalers have side effects. Thirty eight percent (38%) of the patients believed inhalers are addictive. Misconceptions regarding inhalers and its usage in asthma and COPD patients are common in Pakistan. These misconceptions not only lead to poor compliance with medications prescribed but also to frequent visits to hospitals. There is a need to educate patients in the country regarding inhalers in order to improve not only their symptoms, but also to improve their quality of life.

Abstract
Dosage form is a mean used for the delivery of drug to a living body. In order to get the desired effect the drug should be delivered to its site of action at such rate and concentration to achieve the maximum therapeutic effect and minimum adverse effect. Since oral route is still widely accepted route but having a common drawback of difficulty in swallowing of tablets and capsules. Therefore a lot of research has been done on novel drug delivery systems. This review is about oral dispersible tablets a novel approach in drug delivery systems that are now a day's more focused in formulation world, and laid a new path that, helped the patients to build their compliance level with the therapy, also reduced the cost and ease the administration especially in case of pediatrics and geriatrics. Quick absorption, rapid onset of action and reduction in drug loss properties are the basic advantages of this dosage form.

Abstract
This study was done to find the commonest variety of sinonasal malignancy and its association with sex.This cross-sectional study was conducted in the Department of Otolaryngology - Head & Neck Surgery Department, Dhaka Medical College & Hospital and in the Department of Otolaryngology - Head & Neck Surgery Department, Bangabandhu Sheikh Mujib Medical University between January 2009 and December 2009. A total of 146 cases of sinonasal malignancy were consecutively included in the study. The diagnosis was confirmed by histopathology. The mean age was 47.8 years (range: 22-75 years). Over three-quarters (77%) of the patients were male with male to female ratio being 3:1. Nearly one-third (30.8%) of the patients was farmer and over one-third (36.3%) was illiterate. The right sinonasal region was involved in 48.6% cases, left sinonasal region in 39% and both sinonasal region in 12.4% cases. Histopathological diagnosis of sinonasal malignancy revealed that squamous cell carcinoma accounted for 82.9% of sinonasal malignancies, 9.6% adenocarcinoma and the rest were olfactory neuroblastoma, adenoid cystic carcinoma and mucoepidermoid carcinoma. About 96.6% of the tumours involved nasal cavity, 97.9% maxillary sinuses, 17.8% frontal sinuses, 48.6% ethmoidal sinuses and 13% sphenoid sinuses. Over 80% of patients were smoker. Exposure to wood dust was found in 26% of cases. Lather tanning in 4.8% of cases and welding in 4.1% of cases. T staging shows that nearly half (48.6%) of the patients lesion was T2, 29.5% T3, 19.9% T4 and 2.1% T1. None of the patients exhibited lymph node involvement or distant metastasis. Males tend to develop squamous cell carcinoma significantly more than the females with risk of acquiring squamous cell carcinoma being nearly 3(1.1-7.1) times higher in male than that in female (p=0.022). The study concludes that the most common histopathological variety of sinonasal malignancy is squamous cell carcinoma and males are prone to develop this malignancy more frequently than the females.

Abstract
There is a relationship between the left ventricular diastolic dysfunction with uncontrolled diabetes mellitus. A cross sectional study was designed to see the association of uncontrolled diabetes mellitus with diastolic dysfunction of the heart. The study was conducted from April 2012 to March 2013 in the department of cardiology, Mymensingh Medical College Hospital, Mymensingh. Sixty cases were selected as study population; twenty one patients were in Group I with good glycaemic controlled of HbA1C <7% and 39 patients were in Group II with poorly controlled diabetes mellitus having HbA1C ≥ 7%. In the study population male were 43(71.70%) and female were 17(28.30%). Mean age in the two groups were 49.05 ± 6.34 years vs. 53.64 ± 5.38 years, which was not significant difference. Duration of diabetes was <10 years and ≥ 10 years in two groups. Glycaemic status (percentage of HbA1C) was 6.55 ± 0.29% vs. 8.72 ± 1.01% in controlled and uncontrolled diabetic patient groups respectively which was significant difference. Diastolic dysfunction was found more in uncontrolled diabetic patient (patients having HbA1C% ≥ 7%) than controlled diabetic patients (HbA1C <7%). Grade I diastolic dysfunction was in uncontrolled and controlled glycaemic status were 33(84.60%) and 04(19.00%). The difference was statistically significant. Diastolic dysfunction in type 2 diabetic subjects was significantly higher as compared to the well control group (p<0.001). And this study concluded as - Diastolic dysfunction is more common in patient with poorly controlled diabetes mellitus.

Abstract
BACKGROUND There is a high prevalence of diabetes mellitus type-2 (T2DM) and osteoporosis are problems worldwide. In this study, we evaluated the correlation between T2DM and bone turnover in diabetic obese postmenopausal Saudi women. SUBJECTS AND METHODS The present study included total of 65 T2-DM obese postmenopausal Saudi women, (36 uncontrolled, 29 controlled). The following serum biochemical parameters were evaluated [fasting blood glucose (FBG), total calcium (Ca), phosphorus (Pi), parathyroid hormone (PTH), 1,25-(OH)2 Vitamin D3, osteocalcin (OC), procollagen (PICP) and cathepsin k (Cath K)]. RESULTS Serum OC levels were significantly decreased in diabetic obese postmenopausal group compared to their respective healthy group (P < 0.004). PICP and Cath K were significantly elevated in diabetic postmenopausal group compared to the healthy group (P < 0.024 & 0.001). A significant elevation in 1,25(OH)2 Vitamin D3, Ca and Pi levels in diabetic obese postmenopausal patients group compared to the healthy group. However, a non-significant changes was observed in serum PTH level between different groups. CONCLUSION In this study, the changes in the biochemical parameters and bone turnover markers in obese women are strong risk factors for diabetes development that may contribute to osteopenia and osteoporosis. The study showed the strong effect of T2DM on biochemical markers of bone turnover in obese postmenopausal Saudi women.

Abstract
Abstract
Background
The aim of the study was to identify whether a standard supervised exercise programme (SEP) for patients with intermittent claudication improved specific measures of functional performance including balance.
Methods
A prospective observational study was performed at a single tertiary vascular centre. Patients with symptomatic intermittent claudication (Rutherford grades 1–3) were recruited to the study. Participants were assessed at baseline (before SEP) and 3, 6 and 12 months afterwards for markers of lower-limb ischaemia (treadmill walking distance and ankle : brachial pressure index), physical function (6-min walk, Timed Up and Go test, and Short Physical Performance Battery (SPPB) score), balance impairment using computerized dynamic posturography with the Sensory Organization Test (SOT), and quality of life (VascuQoL and Short Form 36).
Results
Fifty-one participants underwent SEP, which significantly improved initial treadmill walking distance (P = 0·001). Enrolment in a SEP also resulted in improvements in physical function as determined by 6-min maximum walking distance (P = 0·006), SPPB score (P < 0·001), and some domains of both generic (bodily pain, P = 0·025) and disease-specific (social domain, P = 0·039) quality of life. Significant improvements were also noted in balance, as determined by the SOT (P < 0·001).
Conclusion
Supervised exercise improves both physical function and balance impairment.

Abstract
Abstract
Background
The aim was to compare costs and utilities of percutaneous transluminal angioplasty (PTA), a supervised exercise programme (SEP) and combined treatment (PTA + SEP) in patients with intermittent claudication (IC) to establish the most cost-effective treatment.
Methods
Patients with IC due to femoropopliteal disease were randomized to receive PTA, SEP or PTA + SEP. Assessments were performed before, and at 1, 3, 6 and 12 months postintervention. Clinical and quality-of-life indicators were recorded. The SF-6D Health Utilities index was calculated from the Short Form 36, plotted, and quality-adjusted life-years (QALYs) were generated by calculating the area under the curve. Costs were calculated using National Health Service 2009–2010 payment-by-results tariffs and the National Institute for Health Research Clinical Research Network Investigation pricing index, and adjusted for reinterventions. Cost per QALY and incremental costs were calculated, and sensitivity analyses performed.
Results
A total of 178 patients (PTA, 60; SEP, 60; PTA + SEP, 58) were randomized. All treatments resulted in significant improvement in the SF-6D index (P < 0·001). There was no significant difference between treatments in mean QALYs gained (PTA: 0·620, 95 per cent confidence interval 0·588 to 0·652; SEP: 0·629, 0·597 to 0·660; PTA + SEP: 0·649, 0·622 to 0·675). The adjusted mean cost per procedure was significantly higher for PTA (€7301·74) compared with SEP (€3866·49) and PTA + SEP (€6911·68) (P < 0·001). The cost per QALY was significantly higher for PTA (€11 777·00) compared with SEP (€6147·04) and PTA + SEP (€10 649·74). QALYs were lost when PTA alone was used as first-line treatment in comparison with SEP or PTA + SEP. These results were robust and valid in sensitivity analyses.
Conclusion
Supervised exercise is the most cost-effective first-line treatment for IC, and when combined with PTA is more cost-effective than PTA alone.

Abstract
The phylogenetic relationships of 60 accessions of the genus Hordeum (29 Mediterranean and 20 middle-Asian wild accessions, together with nine American accessions and two of unknown origin), representing together nine species, were investigated by AFLP markers. Three hundred sixty six AFLP fragments were used for studying the molecular genetic diversity among the studied species, 339 out of them were polymorphic. Forty seven protein bands were obtained from the water soluble and the water insoluble seed storage protein by SDS-PAGE electrophoresis of 18 accessions representing nine species (two accessions/species). One band was common to all species and the other 46 bands were polymorphic. The phylogenetic tree deduced from AFLP analysis is concordant to a large extent with that deduced from seed storage protein. Highly significant cophenetic correlation coefficient was obtained between both AFLP (0.96) and seed storage protein (0.89) indicating the reliability of the results. The studied taxa were clustered according to their genome type. All Mediterranean and middle-Asian wild accessions could be integrated into the existing phylogenetic scheme.

Abstract
BACKGROUND There is a lack of evidence on whether graduates from different medical schools perform differently in postgraduate examinations. OBJECTIVE To evaluate the variations in performance of UK medical graduates in Member of the Royal College of Obstetricians and Gynaecologists (MRCOG) examination. METHODS A retrospective analysis of performance of 1335 doctors graduating in UK medical schools who entered the Part 1 MRCOG and 822 doctors taking the Part 2 MRCOG written examination for the first time between 1998 and 2008. The main outcome measures were to evaluate medical school effects, gender effects and academic performance effect. RESULTS Graduates of UK medical schools performed differently in the Part 1 and Part 2 written MRCOG examination. The graduates of Oxford (pass rate 82.6%), Cambridge (75%), Bristol (59.3%) and Edinburgh (57.5%) performed significantly better and the graduates of Liverpool (26.8%), Southampton (21.8%) and Wales (18.2%) performed significantly worse than the remaining cohort in the Part 1 examination. The candidates of Newcastle (88.9%), Oxford (82.4%), Cambridge (81%) and Edinburgh (78.2%) performed significantly better and the graduates of Glasgow (49.2%) and Leicester (36.2%) have significantly underperformed compared with the remaining cohort in Part 2 written examination. There was no difference in the success rates of male (47.5%) and female (42.0%) candidates in the Part 1; however, female candidates had a significantly better success rate in the Part 2 written examination than male candidates (65.6% vs 52.9%). CONCLUSION These results show that there is variation in performance among the graduates from different medical schools in the Part 1 and Part 2 MRCOG written examination.

Abstract
Due to difficult anatomical position nasopharyngeal carcinoma (NPC) is always challenging problems both from the diagnostic and therapeutic corner. A 24 years old lady came to our Department of Otolaryngology and Head-Neck Surgery with the complaints of epistaxis, right sided neck swelling, nasal obstruction and headache. On digital palpation Nasopharyngeal mass was found. We took biopsy from nasopharynx under indirect vision but report was not conclusive. Then we did CT scan, nasendoscopy. Nasendoscopy showed bilateral ethmoidal polyp with nasopharyngeal mass. We took biopsy from the nasopharyngeal mass and confirmed the diagnosis.

Abstract
Abstract
Background
The aim was to compare percutaneous transluminal angioplasty (PTA), a supervised exercise programme (SEP) and combined treatment (PTA plus SEP) for intermittent claudication due to femoropopliteal arterial disease.
Methods
Consenting patients with femoropopliteal arterial lesions were randomized to one of three treatment arms: PTA, SEP, or PTA plus SEP. All patients received optimal medical treatment. Patients were assessed at baseline and 1, 3, 6 and 12 months after intervention. Clinical (ankle pressures, walking distances, symptoms) and quality-of-life (QoL) outcomes (Short Form 36, VascuQol) were analysed.
Results
A total of 178 patients (108 men, median age 70 years) were included. All three treatment groups demonstrated significant clinical and QoL improvements. One year after PTA (60 patients, 8 withdrew), 37 patients (71 per cent) had improved (16 mild, 16 moderate, 5 marked), nine (17 per cent) showed no improvement and six (12 per cent) had deteriorated. After SEP (60 patients, 14 withdrew), 32 patients (70 per cent) had improved (19 mild, 10 moderate, 3 marked), six (13 per cent) showed no improvement and eight (17 per cent) had deteriorated. After PTA plus SEP (58 patients, 11 withdrew), 40 patients (85 per cent) had improved (18 mild, 20 moderate, 2 marked), seven (15 per cent) showed no improvement and none had deteriorated. On intergroup analysis, PTA and SEP alone were equally effective in improving clinical outcomes, although the effect was short-lived. PTA plus SEP produced a more sustained clinical improvement, but there was no significant QoL advantage.
Conclusion
For patients with intermittent claudication due to femoropopliteal disease, PTA, SEP, and PTA plus SEP were all equally effective in improving walking distance and QoL after 12 months.

Abstract
Chylothorax is a rare clinical condition that can be attributed to a damaged thoracic duct. The condition is suggested by aspiration of milky white fluid from the pleural cavity and is commonly associated with either malignant diseases or trauma (e.g. cardiothoracic surgery). We present the case of a 15-year-old boy with chylothorax, whose effusion was due to constrictive pericarditis. The definitive treatment of chylothorax involves identification and management of the underlying pathology. We suggest that when dealing with cases of chylothorax, constrictive pericarditis should be considered among the causes.

Abstract
Neurogenic tumours of the mediastinum are most commonly present in the posterior mediastinal compartment. Schwannomas, being the most frequently encountered type, can be either benign or malignant, although the former is more common. They typically appear as an asymptomatic mass on radiographic imaging. These tumours with spindle-shaped cells are often asymptomatic, and are routinely detected on standard pulmonary radiography. However, computed tomography and magnetic resonance imaging, especially for posterior mediastinal tumours, provide additional information and help to determine its possible extension to adjacent structures. Therefore, radiographic and histopathological examinations are vital diagnostic tools in the detection of these silent tumours. Complete surgical resection using video-assisted thoracic surgical technique is the mainstay of treatment, and offers an excellent prognosis.

Abstract
Leaves of sunn hemp (Crotalaria juncea) showing geminiviral symptoms were collected from Lucknow, India during rainy season in 2008. DNA template isolated from the symptomatic leaf tissues were subjected to polymerase chain reaction (PCR) using specific primers to amplify coat protein (CP) gene of DNA-A as well as betasatellite DNA associated with the leaf curl disease. CP gene showed 97% sequence identity with that of Cotton leaf curl Burewala virus (CLCuBwV). Further, the betasatellite DNA molecule revealed sequence similarity with previously characterized betasatellite DNA of begomoviruses affecting malvaceous crops from different regions of India and Pakistan. Maximum similarity (>90%) of betasatellite DNA under study was observed with Cotton leaf curl Multan betasatellite (CLCuMB-[Pak: Mul17:08) and other betasatellite DNA from Pakistan thus confirming possible infection of C. juncea with begomovirus. A complementary sense open reading frame (ORF) βC1 is present at nucleotide position 194-550. Sequence comparison of this ORF with other members of begomoviruses further confirmed association of a begomovirus with C. juncea. The betasatellite DNA when expressed under the control of CaMV35S promoter Nicotiana tabacum, showed leaf deformities. Our results demonstrated that a malvaceous betasatellite is adapted by a nonmalvaceous host and causes similar disease symptoms.

Abstract
Seventy patients of differentiated thyroid carcinoma (DTC) irrespective of age and sex were selected in ENT Department of Bangabandhu Sheikh Mujib Medical University, Dhaka Medical College Hospital and Rangpur Medical College Hospital who were admitted from March 2003 to March 2005. Female were more commonly affected (2.6:1) Papillary carcinoma was more common in 31-50 years of age and follicular carcinoma (ca) common in 41-50 years of age. Among the differentiated thyroid carcinoma papillary carcinoma found 77.15% and follicular ca. found 22.85%. Lymph node metastasis was more common in papillary (35%) than follicular carcinoma (12.5%). But distant metastasis was more common in follicular (12.5%) than papillary carcinoma (3.70). Maximum lymph node metastasis was found in level 3(55%), level 2(45%).

Abstract
Monopartite begomoviruses comprise DNA-A as the main genome and associated satellite DNAs. Viral DNA extracted from guar (Cyamopsis tetragonoloba) showing leaf curl symptoms exhibited positive amplification of coat protein (CP) gene of DNA-A component, suggesting the presence of begomovirus. Full length DNA-A was amplified by primer pair re-designed from CP gene nucleotide sequence. The associated alphasatellite and betasatellite DNA molecules were amplified and sequenced, confirming the presence of monopartite begomovirus. Sequence comparisons showed 89% identity with other begomoviruses. The Neighbor-Joining tree based on full length DNA-A nucleotide sequence showed that the guar infecting begomovirus clustered separately from other known begomoviruses. The betasatellite shared a high (96%) nucleotide identity to Cotton leaf curl Multan betasatellites. The alphasatellite showed 91% nucleotide identity to alphasatellite associated with begomovirus infecting Okra. Recombination analyses showed three recombinant fragments in DNA-A, two in betasatellite, and four in alphasatellite. The results suggest that the begomovirus identified in this study was a new recombinant virus. Its name was proposed as Cyamopsis tetragonoloba leaf curl virus (CyTLCuV).

Abstract
BACKGROUND Tobacco prevention studies show that graphic health warnings are more effective than text warnings, but there are no data on the effectiveness of different types of graphic health warnings in a Pakistani population. Even marginal differences in the effectiveness of genres can be of potential significance for public health. OBJECTIVE To study the effectiveness of different types of graphic tobacco warnings in a Pakistani population. STUDY DESIGN We presented ten anti-smoking warnings to randomly selected volunteers (n = 170) and recorded their opinion on the effectiveness of each warning. The warnings were based on a range of images aimed at the diverse population interviewed. A grading scale based on appeal, application, educational potential and motivation towards cessation was used to produce a composite grade of perceived effectiveness of the warning. RESULTS Our results indicate that graphic warnings reach a greater proportion of the population than text warnings. Those appealing to logic, and those inculcating a sense of fear by showing a deleterious outcome of smoking, were judged likely to be most effective in motivating smokers to quit and preventing experimental smokers from forming a habit.

Abstract
Manipulation under anesthesia has been used to speed up the recovery of frozen shoulder (FS), which is said to be a self-limiting disease. This is a randomized prospective clinical trial performed in a tertiary care hospital. Thirty-one patients with idiopathic unilateral frozen shoulder underwent suprascapular nerve block and intraarticular local anesthesia with Methyl prednisolone acetate followed by manipulation of the glenohumeral joint. Differences in range of motion and pain were assessed before manipulation and at 7 days 6 weeks and 12 weeks. Passive range of motion increased significantly for abduction, external rotation, and internal rotation. Significant decrease in visual analogue pain (VAS) scores between initial and follow-up assessments was observed. Our results revealed that manipulation under suprascapular nerve block and intra-articular local anesthesia is a very simple, safe, cost effective and minimally invasive procedure for shortening the course of an apparently self-limiting disease and can improve shoulder function and symptoms quickly.

Abstract
Juxta-articular, subperiosteal osteoid osteomas arising around the ankle are unusual. Tumors arising on the neck of the talus commonly produce symptoms mimicking monoarticular arthritis. Patients are usually treated for arthritis or ankle sprain, which often leads to a delay in definitive diagnosis. Here we present a case of osteoid osteoma of neck of talus which was presented as ankle pain. It puzzled us until MRI was done. Diagnostic dilemma and delay can be avoided by high index of suspicion. The patient was treated with open removal of the tumor. We also present brief review of literature about juxta-articular, subperiosteal osteoid osteoma which is uncommon from the typical osteoid osteoma occurring elsewhere in the body.

Abstract
Slipped capital femoral epiphysis (SCFE) is a common adolescent problem in the western populations but it is extremely rare in the Asian regions. We report a case management of a teen age boy (16 years old at the time of operation) with bilateral SCFE. After fall injury, the boy sustained SCFE on the left side and was treated. Again after six months with trivial injury he got SCFE on the right side. In both cases the boy was managed by closed reduction and percutaneous cannulated cancelleous screws fixation under c-arm fluoroscopy control. The cannulated screws were removed after one year of insertion confirming of a good fusion in plain x-ray films. During the regular follow up of up to one year the patient had good hip functions and other daily activities. The patient lost to follow up for about three years and suddenly presented to us with restricted hip joints movements and other activities. The x-ray showed tilted pelvis, reduced, incongruent hip joint spaces with malunited femoral physis, widened neck and tilted femoral head along with visible physeal scan on both sides. The patient and patient party are still satisfied with these results and reluctant to go for further surgical intervention.

Abstract
OBJECTIVES To study the awareness, perceptions and practice of university students in Karachi, Pakistan, with regard to shisha (waterpipe) smoking. DESIGN Cross-sectional survey conducted among students at four different universities of Karachi, selected through random cluster sampling. RESULTS A total of 450 participants, 59.6% males (n=268) and 40.4% females (n=182), were included in the study. About half of the participants reported having ever smoked shisha (n=241, 53.6%). On examining factors associated with starting shisha smoking, curiosity was found to be the most common reason (n=148, 61.4%), followed by pleasure-seeking (n=113, 46.9%), peer pressure (n=55, 22.8%), boredom (n=43, 17.8%) and stress (n=26, 10.8%). Of 241 participants who had ever smoked waterpipes, the majority (n=149, 61.8%) were current smokers. A vast majority of participants (n=269, 60%) considered waterpipe smoking to be less unhealthy than cigarette smoking. Boredom in youth, use of waterpipe in leisure activities and peer pressure were identified as the most common reasons for the escalating popularity of waterpipe smoking in Pakistan. CONCLUSIONS Waterpipe smoking is very popular among Pakistani university students, and knowledge among university students about the dangers of waterpipe smoking is alarmingly low.

Abstract
Hydatid disease is caused by the tapeworm of genus ;Echinococcus. Genus Echinococcus has different species including Echinococcus vogeli, Echinococcus granulosus and Echinococcus multilucularis. Echinococcus granulosus is the most common cause of hydatid disease in humans. This disease can take place either directly through ingestion of parasite eggs from contact with infected dogs or indirectly from the ingestion of contaminated water or food. Infestation of hydatid disease in humans most commonly occurs in the liver (55-70%), followed by the lungs (18-35%). Bone hydatidosis however is very rare,whenever it occurs; it is usually secondary to visceral involvement. We present herein a case of primary hydatid cyst involving superior pubic ramus in a 43 years male patient, which is not a common site for the occurrence of this disease. Diagnosis is usually delayed if high index of suspicion is not there. MRI is a good tool for reaching diagnoses.

Abstract
SETTING Aga Khan University Hospital, Karachi, Pakistan. OBJECTIVE To prospectively compare 30-day mortality with CURB65 and CRB65 scores and the three mortality risk groups (low, intermediate and high) based on these scores in hospitalised patients with community-acquired pneumonia (CAP). DESIGN Longitudinal observational cohort study of adult in-patients fulfilling the definition of CAP between October 2006 and May 2007. RESULTS A total of 137 patients was included. The 30-day mortality was 13.1%. Areas under the receiver operating characteristic curve for CURB65 and CRB65 scores were respectively 0.863 and 0.835. Odds of death among patients in the high mortality risk group of CURB65 score was 15.4 and those of CRB65 was 11.1 compared with the low and intermediate mortality risk groups combined as reference. CURB65 and CRB65 scores classified 46% and 24.8% patients, respectively, into the low mortality risk group. Length of hospital stay increased with the CURB65 score-based mortality risk groups but not with those based on the CRB65 score. CONCLUSION CURB65 and CRB65 scores showed no significant difference in predicting 30-day mortality. Both scores, and the CURB65 score in particular, categorised reasonable proportions of patients into the low mortality risk group who could be discharged from the emergency room and managed as out-patients.

Abstract
Supracondylar fractures of humerus in children are common injuries. Displaced fractures are inherently unstable. Conservative treatment results in malunion. Open reduction and internal fixation (ORIF) is more invasive and recovery is prolonged. From September 2004 to September 2005, 102 displaced supracondylar fractures of humerus, aged between one and half year to 13 years, were treated using close reduction and percutaneous Kirschner (K) wire fixation under c-arm fluoroscopy. Seventy nine patients were treated by cross K-wires and in twenty three cases lateral two K-wires were put. Above elbow plaster of paris back slab was applied in all cases for at least four weeks. Back slab, K-wires were removed after four weeks and elbow range of motion exercise was started. Results were analyzed using Flynn's criteria. All patients were followed up to 14th week postoperatively. In cross K-wire group(N=79) 70.8% had excellent, 22.7% good, 3.8% fair and 2.5% had poor results at eight weeks follow up which was improved to 91.1% excellent, 6.3 good, 1.2% fair and 1.26% poor results at 14 weeks follow up.

Eight patients got superficial pin tract infection and seven patients sustained ulnar nerve injury post operatively. We recommend this procedure for displaced supracondylar fractures in children as it is safe and cost effective procedure with acceptable complication rates.
