Results of Subtrochanteric Femoral Fractures Fixation by Proximal Femoral Locking Compression Plate.

The treatments of subtrochanteric femoral fractures are a challenge. It accounts about 10.0% to 34.0% of all hip fractures with a high complication rate. This area consists of mostly cortical bone with high stress generation thus heal slowly. The fracture is too proximal to adequately control with implants for femoral shaft and too distal to control with implants for intertrochanteric fractures. The intrinsic insecurity of this fracture and forces of the muscles with comminuted medial calcar is giving the fracture a tendency to varus crumple. Extramedullary implants are associated with higher rate of implant failure while intramedullary nails are not suitable for short proximal segment and wide medullary canal. Recently proximal femoral locking compression plate (PF-LCP) has been applied in treatment of proximal femur including subtrochanteric fractures. It has an excellent result in respect of union, fewer complications and early rehabilitation. The aim of this study was to assess the rate and time taken for union of fractures by PF-LCP and determine perioperative parameters. This prospective study was conducted from March 2019 to September 2020 at Mymensingh Medical College Hospital through non randomized purposive sampling. Total 25 patients aged above 18 years irrespective of sex with closed subtrochanteric fracture were included but pathological fractures, multiple injuries were excluded from the study. Union status evaluated by Radiographic Union Score for Tibial (RUST) fracture of Whelan; where antero-posterior and lateral radiographs (X-ray) based assessment of healing of the four cortices done. The entity cortical scores were added to give an entire score; 4 being the least amount demonstrating fracture are positively not healed and 12 being the highest score representing that the fracture is positively healed. The mean age of the patients was 42.04±14.97 years with range 22-70 years. Majority of patients were male (60.0%) and most of injury (64.0%) due to road traffic accident with most fractures was Seinsheimer type III (48.0%). Average operative time was 121.92 minutes, follow up period was 41.12 weeks (24-48 weeks) and time taken for union was 14.16 weeks (11-28 weeks). According to RUST scores; fracture union rate 88.0% with delayed union 12.0% and no nonunion. There were two patients with superficial wound infection and no implant failure. This study concludes that PF-LCP is a safe and reliable implant for the treatment of subtrochanteric femoral fractures.

Evaluation of Results of Primary Repair of Open Tendo-Achilles Injury in the Department of Casualty, MMCH, Bangladesh.

Achilles tendon injury has been increasing over recent years due to a variety of causes. The injury of the Achilles tendon is a disabling condition, which is difficult to treat if there is a gap or defect between the two ends of the disrupted tendon. Patients with a rupture of the Achilles tendon should be operated without delay. Most of the people in our country use flat pan in the latrine, which are at a same level of the toilet floor. Surface of the toilet pan breaks down and cause sharp cut. Some of the cases of open tendon injuries occur due to road traffic accident, cut by broken glass and also assault. It is generally accepted that surgical repair of fresh ruptures of the Achilles tendon gives excellent results. Objective of the study was to find out the evaluation of the results of primary repair of Open tendo-achilles injury (OTAI). This prospective study was done in the department of Casualty of Mymensingh Medical College Hospital, Bangladesh in the period of Octy 2021 to June 2022. Patients who came with OTAI in casualty department were selected randomly. All cases were selected as OTAI, without associated injury of other leg muscles, posterior tibial artery and nerve within 12 hours. All patients underwent primary end to end repair by Modified Kessler's method. Evaluation of the results of primary repair of OTAI were carried out and were find out the common causes of injury, age and sex incidence, level of injury and to proposed a protocol for treating such cases in comfortable, cheap and convenient way for the patients. Operations were done at Casualty operation theatre (COT). Then 48 patients were followed up at the Department of Casualty. Among them 43(89.58%) of patients were able to stand on tip toes, 4(08.33%) of patients were not stand on tip toes of affected foot unsupported but able to stand on tip toes supported, 1(02.08%) of patients failed to stand on affected foot unsupported due to severe infection and wound gap. Final result were Excellent - 29(60.0%), Good - 14(30.0%), Fair - 4(8.0%), Poor - 1(2.0%). Repair of OTAI is not difficult but early diagnosis, proper surgical toileting, meticulous repair; adequate post-operative management is the key of success. So, the result of this study, treatment protocol can be followed, which is easy for surgeon and convenient and cheap for the patients.

Pattern of ENT Diseases in Children: A Peripheral Military Hospital Based Study.

This study was aimed to find out the hospital based prevalence of paediatric ENT disorders in an ENT OPD of a peripheral military hospital of Bangladesh Armed Forces. This observational study was carried out at ENT out patient department of CMH Momenshahi, from 1st April 2017 to 31st March 2020. Irrespective of age and sex a total of 4612 children, between the ages of 0-14 years were included in this study. All types of ENT disorders were taken in to account. Data were obtained after ENT examination and necessary investigations. Total 4612 cases were studied. Male children (52.2%) were affected more and most of the children belongs the 6-10 years age group (44.4%).Throat related disorder (40.7%) were predominant followed by ear (34.8%). The most common ENT disorders were Chronic Tonsillitis (21.8%) followed by acute otitis media (16.1%) and pharyngitis (9.8%). Rate of Chronic otitis media (COM) was only 46(1%). ENT diseases are one of the major health problems among children. In addition to improved health education, socioeconomic status and better access to health care facilities; provision of early ENT specialist consultation may significantly reduce chronic or recurring symptoms and long term morbidities of common ENT disorders in children.

Investigation of groundwater and its seasonal variation in a rural region in Natore, Bangladesh.

In Bangladesh, groundwater is the most widely used source of drinking water for rural communities. However, the groundwater quality is degraded by natural contaminants and anthropogenic pollution. Groundwater is a reliable and sustainable source of safe water for irrigation and domestic purposes, especially during the dry season. The water quality assessment data for the study area was not found in the literature. This study aims to assess groundwater quality and seasonal variation in a rural area of five unions of Bagatipara Upazila, Natore, and its suitability for drinking purposes by measuring the Water Quality Index (WQI). The groundwater of five unions, namely Dayarampur, Bagatipara, Faguardiar, Jamnagar, and Pacca, has been selected for investigation. The electrical conductivity (EC), color, and turbidity exceeded the ECR guidelines. EC showed a positive correlation with total dissolved solids (TDS), total solids (TS), and turbidity. On the other hand, dissolved oxygen (DO), hardness, chloride, carbon-di-oxide (CO2), and iron (Fe) concentrations varied based on the location of the sampling points. The bacteriological parameters TC and E. coli were found in most of the samples, which indicate the potential sources of contaminants such as septic tank leakage and inadequate waste disposal systems. The groundwater quality was found not to be influenced by seasonal variation except by pH, DO, and CO2. The Water Quality Index (WQI) spatial mapping demonstrated that during the post-monsoon period, the water quality of the central part of Bagatipara upazila was in 'good' condition, which was in Bagatipara, Fagurdiar, and Pacca unions, whereas during the pre-monsoon season, the 'good' condition was found very limited to Fagurdiar union only. The study revealed that the groundwater of Bagtipara Upazila is not suitable for drinking water due to the presence of TC and E. Coli as well as 'poor' to 'unsuitable' conditions in most of the areas based on WQI.

Association of Serum Homocysteine Level with Parkinson's Disease.

Parkinson's disease (PD) is a chronic, progressive neurodegenerative disease with unknown etiology. Some previous studies suggest that elevated serum homocysteine level is a risk factor for stroke, ischemic heart disease; atherosclerosis and neurodegenerative diseases like Parkinson's disease. Serum homocysteine level relates with Parkinson's disease through various mechanisms including gene defect, apoptosis, oxidative stress and DNA damage. Some recent studies reveal that serum homocysteine level is elevated in Parkinson's disease patient compared to healthy individuals. This study was aimed to compare the serum homocysteine level in Parkinson's disease patients and age and sex matched apparently healthy individuals. This was a case control study which was conducted in Department of Neurology and Medicine, Mymensingh Medical College Hospital, Mymensingh during November 2019 to April 2021. Total 55 cases of Parkinson's disease patients and age and sex matched 55 apparently healthy controls were enrolled in this study. Demographics and clinical data were collected using structured case record form and adopting purposive type of sampling method. Serum homocysteine level was measured in both case and control groups. The study reveals that, average age of the patients and control group was in sixth decade. Male predominance was found with male to female ratio was 1.5:1 in case group. Both groups showed almost similar demographic profiles. Twenty-nine (52.72%) patients of Parkinson's disease observed higher serum homocysteine level in contrast to only 8(14.54%) in control group. The mean serum homocysteine ±SD was 15.43±6.04µmol/L in case group and 10.04±5.31µmol/L in control group; the difference was statistically significant (p=0.001). Mean serum homocysteine levels were measured progressively higher with increased duration and advanced stages of disease. It was concluded that, serum homocysteine level is higher in Parkinson's disease patients than normal healthy individuals. In addition, there was significant positive correlation of elevated serum homocysteine with increased duration of Parkinson's disease and advanced stages of the disease.

Association between Serum Vitamin D Level and Acute Ischemic Stroke.

Stroke is one of the most common neurological disorder and third most common cause of death in the world. Low vitamin D concentrations have been shown to predict risk of cardiovascular disease and all-cause of mortality. The aim of this study was to estimate serum vitamin D level in acute ischemic stroke patients. This comparative cross-sectional type of study was conducted in the Department of Neurology and Department of Medicine at Mymensingh Medical College and Hospital, Bangladesh from November 2017 to June 2019 with a total number of 100 study subjects. Total fifty patients with acute ischemic stroke were enrolled in Group A and another fifty age and sex matched volunteer subjects were enrolled in Group B with no prior history of stroke or transient ischemic attacks. Serum vitamin D levels, fasting plasma glucose and lipid profile were assessed in both groups and compared with each other. P value <0.05 was considered as significant in the study. Mean fasting blood sugar, serum fasting total cholesterol (TC), serum fasting triglycerides, serum fasting Low density lipoprotein (LDL) were significantly higher in Group A than Group B (p<0.05). Serum vitamin D level in Group A was 25.28±8.47ng/ml and in Group B was 30.90±5.80, (p=0.001). Insufficient vitamin D level was found in 52.0% of ischemic stroke patients and in 30% of healthy controls (p=0.0002). Vitamin D deficiency was found in 20.0% ischemic stroke patients and 10.0% in healthy controls. This study demonstrates a positive association between low serum vitamin D level and acute ischemic stroke. Further studies are required to determine whether vitamin D supplementation could improve functional outcome in patients with ischemic stroke.

Evaluation of Determinants to Achieve Target Urea Reduction Ratio on Maintenance Hemodialysis Patients in Bangladesh.

Among patients with chronic kidney disease stage-5 who are treated with dialysis, the urea clearance during hemodialysis is a determinant of the mortality. Decreased serum albumin, serum calcium but increased phosphorus is associated with reduction of URR and mortality in these patients. This study was to compare two groups Urea Reduction Ratio (URR) and different type of biochemical parameters. URR was aimed to target according to Kidney Disease Outcomes Quality Initiative (KDOQI) guideline. This study was an observational study was carried out in the department of Nephrology. Serum Albumin, serum calcium, phosphate, hemoglobin and pre dialysis urea, post dialysis urea were measured from blood sample. URR was calculated by = (1- postdialysis urea/predialysis urea) × 100. Among the patients who under went hemodialysis, 17.31% patients URR was more than 65.0% and Mean±SD of URR was 67.21±1.9%. On the other hand, 82.68% patients URR was less than 65.0% and Mean±SD of URR was 57.4±5.2%. Most of the Biochemical parameters in this study were significantly different between two groups. Where as, there was no significant difference in Age, Sex, Body Mass Index (BMI). The URR is an accurate indicator, can help determination of adequate dialysis. This study aimed to find out the mean value of the urea reduction ratio and the association of biochemical parameters among End Stage Renal Disease (ESRD) patients on maintenance hemodialysis.

The findings indicated that sexual and gender minority individuals exhibited higher rates of suicidal ideation. The P4 screener showed adequate reliability, convergence, and discriminant validity, and a cutoff score of 1 is recommended to identify individuals at risk of suicidal behavior. CONCLUSIONS: The study supports the reliability and validity of the P4 suicide screener across 42 diverse countries, highlighting the importance of using a cross-cultural suicide risk assessment to standardize the identification of high-risk individuals and tailoring culturally sensitive suicide prevention strategies.

Effect of gamma (γ-) radiation on the opto-structural and morphological properties of green synthesized BaO nanoparticles using Moringa Oleifera leaves.

In this current assessment, BaO synthesized from Moringa Oleifera leaves were irradiated using 0-75 kGy gamma radiation and investigated its physical impacts. The x-ray diffraction (XRD) data demonstrated the synthesis of tetragonal BaO, and no phase deviation was observed after irradiation. As doses are increased, the overall crystallite size were decreased due to an increase in defects and disorders. The tetragonal BaO was evident in Fourier transform infrared (FTIR) spectra prior to and following irradiation, while peak intensities and wavenumbers varied considerably. The as-prepared BaO showed a spherical shape morphology, and Field emission scanning electron microscopy (FESEM) indicated no vital deviations in it after irradiation. As irradiation shifts from 0 to 75 kGy, optical bandgap was increased from 4.55 to 4.93 eV, evaluated using Kubelka-Munk (K-M) equation from UV-vis-NIR spectrophotometer. Opto-electronic and photonic devices have challenges in extreme radiation conditions, such as space and nuclear environments. So, these assessments suggested that BaO can withstand high levels of gamma photon and could be a good option for photonic and optoelectronic instruments in an extreme gamma-ray exposed conditions.

A Case Report on an Unusual Presentation of Pernicious Anemia.

Pernicious anemia is an autoimmune disease leading to impaired absorption of dietary cobalamin. Patients with pernicious anemia can present with multiple hematological, neurological and gastrointestinal complaints. Herein, we have a case of pernicious anemia presenting with alternating bowel habit. This was challenging and unique as the patient didn't have any usual condition responsible for alternating bowel habit and it is not reported in cases of pernicious anemia either. The case is a 46-year-old male who was admitted with alternating bowel habit, paresthesia and fever for the last 6 months. Patient was found to be severely anemic. After full workup, he was diagnosed with pernicious anemia. The patient was treated with IM Injections of Vitamin B12. After 3 months of discharge, the patient was free of all the symptoms. This case emphasizes the importance of investigating anemic patients with alternating bowel habit for pernicious anemia and also the need to exclude other causes of this symptom before labeling it as pernicious anemia only.

Frequency of Post Endoscopic Retrograde Cholangiopancreatography Acute Pancreatitis in an Academic Hospital of Bangladesh.

Post-ERCP acute pancreatitis (PEP) is a common and serious complication with high morbidity and mortality rates. There is a paucity of data on the frequency of PEP in a resource constraint setting like Bangladesh. Hence we have conducted a prospective study to determine the frequency of PEP and the factors associated with its occurrence. This prospective, observational study was carried out in Gastroenterology Department of Dhaka Medical College & Hospital, Dhaka, Bangladesh from April 2018 to December 2018 on the consecutive patients who underwent ERCP. PEP and its severity were diagnosed according to consensus definition. Serum lipase was done in all patients before procedure and 24 hours after procedure or if patient develops abdominal pain after the procedure which became earlier. Total 168 patients were included (mean age 46.97±14.35 years; male 72(43.0%). The most common indication of ERCP was choledocholithiasis 97(58.0%) followed by malignant biliary obstruction 45(27.0%), recurrent pyogenic cholangitis 8(5.0%), chronic pancreatitis 4(2.3%), biliary ascariasis 4(2.3%) and others 10(6.0%). Overall post ERCP complication rate was 46(27.3%) including cholangitis 29(17.3%), pancreatitis 16(9.5%), bleeding 12(7.1%), aspiration pneumonia 4(2.4%) and death 3(1.8%). Regarding the severity of PEP, 50.0%, 43.7% and 6.3% patients developed mild, moderate and severe pancreatitis respectively. Number of cannulation attempts >5 times [22(48%) vs. 17(14%); p=0.001], cannulation attempts duration more than 10 minutes [25(55%) vs. 27(22%); p=0.001], unintentional passage of guide wire into the pancreatic duct [8(17%) vs. 18(15%); p=0.001], pancreatic duct contrast injection [12(26%) vs. 2(1.6%); p=0.001] and pre-cut sphincterotomy [16(35%) vs. 6(4.9%); p=0.001] were significantly different between the patients who developed PEP compared to those who did not. In multiple logistic regressions analysis, pancreatic duct contrast injection was significantly associated with PEP [OR 25.523 with 95% CI (4.049- 100.0%)]. Around ten percent patients had developed PEP. Regarding the severity half of them were mild, 44.0% patients had moderate and 6.0% patient had severe type of pancreatitis. Difficult cannulation, unintentional passage of guide wire into the pancreas, pancreatic duct contrast injection and pre-cut sphincterotomy were associated with PEP. Among them pancreatic duct contrast injection had independent significance in the causation of PEP.

Perceptions of antibiotic stewardship programmes and determinants of antibiotic prescribing patterns among physicians in tertiary hospitals in Bangladesh: implications for future policy and practice.

BACKGROUND: The concerning growth of antimicrobial resistance (AMR) renders common infections life-threatening due to irrational antibiotic use and a lack of effective antimicrobial stewardship programmes (ASPs). AIM: To investigate the awareness, perceptions and practices of physicians regarding ASPs, AMR and antibiotic prescribing in tertiary care hospitals in Bangladesh. METHODS: This hospital-based cross-sectional survey was conducted in 11 tertiary care hospitals across Bangladesh between September 2020 and January 2021. A semi-structured questionnaire was administered through face-to-face interviews for data collection. Descriptive and multi-variate analyses were performed using STATA Version 13. RESULTS: In total, 559 physicians were enrolled in this survey. Overall, 40.6% [95% confidence interval (CI) 36.5-44.8] of physicians reported being aware of ASPs, and this figure was higher in public hospitals compared with private hospitals (43.8% vs 27.1%). None of the study hospitals had any ASP initiatives. More than half (55.1%) of the participants were willing to receive feedback from an ASP on their antibiotic selection. Only 30.9% of respondents stated that they wait for the findings of microbiological tests before prescribing antibiotics, although challenges included empiric use of broad-spectrum antibiotics, delayed laboratory results and the existence of drug-resistant patients. In contrast, physicians aware of ASPs were 33% (adjusted odds ratio 0.67, 95% CI 0.45-0.98; P=0.033) less likely to wait for laboratory results before prescribing antibiotics. However, 42.5% of physicians considered patient affordability of purchasing antibiotics when prescribing. CONCLUSIONS: Physicians' fundamental knowledge of ASPs and rational antibiotic prescription were found to fall short of the standard. Context-specific and integrated ASP activities, availability and use of guidelines, and improved laboratory facilities are required to battle AMR in Bangladesh.

3D Lumerical simulation of silicon photodiodes with microholes for high-speed short-reach intra-datacenter interconnects.

3D simulations are conducted using Lumerical software to study the performance of surface illuminated silicon positive-intrinsic-negative photodiodes with microholes. Drift-diffusion equations are solved including the effects of carrier lifetime due to Shockley-Read-Hall and Auger recombination mechanisms, as well as high field mobility. Lumerical's FDTD tool is used to determine the light absorption in the device. The generation profile is imported to Lumerical's CHARGE tool to determine the transient-limited impulse response. An equivalent circuit of the photodiode with microholes is developed for the simulation of an end-to-end high-speed system. Simulation results show an open eye diagram at 50 Gbps for 20µm×20µm devices.

Hand hygiene compliance and associated factors among healthcare workers in selected tertiary-care hospitals in Bangladesh.

BACKGROUND: Hand hygiene (HH) is a fundamental element of patient safety. Adherence to HH among healthcare workers (HCWs) varies greatly depending on a range of factors, including risk perceptions, institutional culture, auditing mechanisms, and availability of HH supplies. AIMS: This study aimed to evaluate HH compliance and associated factors among HCWs in selected tertiary-care hospitals in Bangladesh. METHODS: During September 2020 to May 2021, we conducted non-participatory observations at 10 tertiary-care hospitals using the WHO's '5-moments for hand hygiene tool' to record HH compliance among physicians, nurses and cleaning staff. We also performed semi-structured interviews to determine the key barriers to complying with HH. RESULTS: We observed 14,668 hand hygiene opportunities. The overall HH compliance was 25.3%, the highest among nurses (28.5%), and the lowest among cleaning staff (9.9%). HCWs in public hospitals had significantly higher odds of complying with HH practices than those in private hospitals (adjusted odds ratio: 1.73, 95% CI: 1.55-1.93). The odds of performing HH after touching a patient were 3.36 times higher compared with before touching a patient (95% CI: 2.90-3.90). The reported key barriers to performing HH were insufficient supplies (57.9%), skin reactions (26.3%), workload (26.3%) and lack of facilities (22.7%). Overall, observed HH supplies were available in 81.7% of wards for physicians and 95.1% of wards for nurses, however, no designated HH facilities were found for the cleaning staff. CONCLUSIONS: HH compliance among HCWs fell significantly short of the standard for safe patient care. Inadequate HH supplies demonstrate a lack of prioritizing, promoting and investing in infection prevention and control.

Correlation between Depth of Medial and Lateral Curvatures of Clavicle.

Having the first bone to ossify clavicle is a bone of pectoral girdle. It is the only bony attachment between the trunk and upper limb. To obtain the precise data that is required to investigate the range in size and morphological features of the human clavicle, a study was undertaken on dry human clavicles which had been sourced from the Department of Anatomy. The purpose for undertaking this study was to obtain baseline data on the clavicular bow in the transverse plane. This cross-sectional descriptive study having some analytical components was done among 150 (65 right and 85 left) fully ossified dry clavicles in Mymensingh Medical College, Bangladesh from January 2020 to December 2020. Sample which met the inclusion criteria was collected through non random sampling technique, from Anatomy department of Mymensingh Medical College and Community Based Medical College Bangladesh. The parameters (the depth of medial and lateral curvatures) were measured with the help of rigid osteometry board and were expressed in millimeter. In the current study, the mean±SD depth of medial curvature of 65 clavicles of right side was 15.54±3.54mm and 15.45±3.24mm of 85 left clavicles. The mean±SD depth of lateral curvature of right side was 11.71±2.54mm and of left side was 9.21±2.31mm. Correlation was done in between depth of medial and lateral curvatures on both sides and the regression line showed positive correlation but these differences were statistically non-significant on both sides.

Outcomes of Varus Derotation Femoral Osteotomy By Angle Blade Plate in Legg-Calve-Perthes Disease for Patient Above Eight Years of Age in The Lateral Pillar B or B/C Group.

Legg-Calve-Perthes disease (LCPD) that starts after 8 years (late onset) usually follow more aggressive course and the long-term outcome is also poor. Treatment method of LCPD that will produce best results is controversial particularly if the patients are with late-onset presentation. This prospective study was conducted from January 2015 to January 2019 at Dhaka Medical College Hospital and Health N Hope Hospital, Dhaka, Bangladesh. We evaluated the radiographic outcomes for patients who had varus derotation femoral osteotomy (VDRO). We followed up 16 patients who had femoral varus osteotomy. All patients were above 8 years of age at clinical onset. The involvement of femoral epiphysis was in either in B or B/C in lateral pillar classification. All patients had MRI done to confirm radiological diagnosis and classification. The mean age was 9.5 years (range, 8 to 12 years). Final outcome was evaluated by using the Stulberg classification which was radiological. Important exclusion criteria were patient with bilateral involvement and requirement of femoral varus >30 degree. We had 81.25% of our patient with satisfactory outcomes. Among them there were Stulberg grade I, 0 cases; Stulberg grade II, 13 cases (81.25%); Stulberg III, 3 cases (18.75%), Stulberg IV and V both 0 case each. The surgical outcomes for varus derotation femoral osteotomy in late onset LCPD patients over 8 years old were showing the good results than other modalities of non surgical and surgical methods.

Role of White Blood Cell Count, Immature to Total Ratio and C-Reactive Protein in Early Detection of Clinically Suspected Neonatal Sepsis.

Despite recent advances in neonatal care, early detection of neonatal sepsis still remains challenging. Positive blood culture is the gold standard for definitive diagnosis of neonatal sepsis but is time consuming and demands a well equipped laboratory setting. Therefore, it becomes imperative to evaluate usefulness of white blood cell count, Immature to total (IT) ratio and C-reactive protein as potential markers in the early diagnosis of neonatal sepsis. The objective of the study was to evaluate role of white blood cell count, IT ratio and C-reactive protein in early detection of clinically suspected neonatal sepsis. This cross-sectional descriptive study was conducted from January 2017 to December 2018 at Special Care Newborn Unit (SCANU) of Rangpur Medical College Hospital, Rangpur, Bangladesh. After parental permission and ethical clearance, a total of 70 eligible neonates were included into the study. Estimation of total white blood cell count, IT ratio and C-reactive protein as well as blood culture were done for each case. Significance for Chi-Square test and Pearson's correlation coefficient test was predetermined as p<0.05. Of the total 70 neonates studied, 19(27.14%) were blood culture positive and most common organism was Escherichia coli (7/14, 37.0%). Among individual and combination tests, CRP was highly sensitive (100%) followed by WBC count (74.94%). Highly specific tests in diagnosing sepsis were combination test of IT ratio and CRP (88.23%) followed by combination test of WBC count and CRP (82.35%). Positive predictive value (PPV) was high for combination test of WBC count and CRP (90.90%) followed by combination test of IT ratio and CRP (90.47%). Negative predictive value (NPV) was high in CRP (100.0%) followed by WBC count (89.19%). IT ratio positively correlated with CRP (p=0.002) and there was significant association between raised CRP and WBC count (p=0.005) in neonatal sepsis. Diagnostic role of both individual and combination tests were significant in early detection of clinically suspected neonatal sepsis while awaiting results of blood culture. However, none of the combination tests were able to achieve 100.0% sensitivity.

Phlebectomy versus Sclerotherapy in Varicose Vein Patients: A Comparative Study.

Varicose veins are part of the spectrum of chronic venous disease and include spider telangiectasias, reticular veins, and true varicosities. It may present without advanced signs of chronic venous insufficiency. Sclerotherapy is a treatment choice for patients with varicose veins of lower extremity; it uses the intravenous injection of chemical drugs to achieve the goal of inflammatory occlusion. Phlebectomy, a minimally invasive procedure usually used for higher diameter of varicose veins at the surface of the skin. Objective of the study was to compare the outcome of Phlebectomy and Sclerotherapy in varicose vein patients. It was a quasi experimental study was conducted in the Department of Vascular Surgery in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka during the period of June 2019 to May 2020. Patients admitted with varicose vein and varicosity of the lower limbs with valves and perforator incompetence in the Department of Vascular Surgery, BSMMU, Dhaka, Bangladesh. During this period 60 patients were selected purposive randomly. Patients were divided to 30 patients were treated with Phlebectomy (Group I) 30 patients were treated with Sclerotherapy (Group II). Data were collected according to the pre-designed semi-structured data collection sheet. After editing data analysis were carried out by using the Statistical Package for Social Science (SPSS) version 22.0 Windows software. This study shows average age 40.73±15.50 years in Phlebectomy (Group I) and 38.43±11.08 years in Sclerotherapy (Group II). Males are more commonly involved than females between two groups which was 76.7% in Phlebectomy (Group I) and 70.0% in Sclerotherapy (Group II). The change CEAP improved to 93.3% in patients who underwent phlebectomy when compared to 83.3% in patients who underwent sclerotherapy. During the follow-up with duplex at treated veins showed 93.3% complete occlusion of treated veins in the phlebectomy group, while only 70.0% of the patients in the sclerotherapy group showed evidence of complete occlusion. In phlebectomy group recurrence of leg varicosities were found 6.7% of the patients, while 26.7% of the patients in the sclerotherapy group. The difference was statistically significant between two groups (p=0.038). This study shows phlebectomy to be much better option than sclerotherapy for the treatment of varicose veins and hence can be used routinely. Both phlebectomy and sclerotherapy not only revealed minimal time taken for return to normal activity but also proved to be safer with regard to complications.

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

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