Background & Objectives: Peritonitis due to hollow viscous perforation is one of the most common surgical emergencies attended by a surgeon on duty. Despite many advances in anti-microbial and supportive care, the mortality rate of diffuse peritonitis remains unacceptably high (10-20%). The treatment of peritonitis and the evaluation of different therapeutic approaches are hampered by lack of precise classification. A scoring system should be able to assess the need, type and quality of the care required for a particular patient. Realizing the need for a simple accurate scoring system in these conditions the present study was undertaken to evaluate the prognosis in patients with perforation peritonitis using Mannheim Peritonitis Index. Materials & Methods: Single centered, observational analytical study conducted in Jubilee Mission Medical College & Research Institute. In our study, we have included 64 patients after meeting the inclusion criteria. As per the study protocol, patient data was collected at the time of admission and intra operatively in the Surgery Department. Mannheim Peritonitis Index score was applied to assess the outcome and data analyzed. Results and Discussion: Out of 64 patients studied, statistically significant correlation was observed between incidence of mortality and the risk factors namely, age more than 50 yrs.(25.9%), presence of organ failure(36.4%), preoperative duration more than 24 hrs.(18.6%), diffuse peritonitis(18.2%) and feacal exudates (45.5%). No statistically significant correlation was observed between incidence of mortality and the risk factors namely female sex, non-colonic origin of sepsis, presence of malignancy. Conclusion: In our study population, all risk factors included in the Mannheim Peritonitis Index namely presence of organ failure; preoperative duration> 24hrs; age>50 years, generalized extension of peritonitis and type of exudate had significant association with adverse outcome while in patients with the non-colonic origin of sepsis, presence of malignancy and of the female sex there was no significant association of these risk factors with adverse outcome (mortality). The overall mortality in our study is 12.5%. Mortality in patients with MPI score < 21 was 0%, 21-29 was 4.3% and >29 was 53.84%. This reproducible scoring system allows a surgeon to determine the severity of intra-abdominal infections, to select a more aggressive management for high risk patients and to be able to inform patient's relatives with greater objectivity.

Background: Fine Needle Aspiration Cytology (FNAC) is worldwide accepted, inexpensive, minimally invasive and very accurate method today especially in commonly encountered clinical problems like salivary gland lesions which range from non-neoplastic lesions like inflammation, cysts, and commonest benign tumours like pleomorphic adenoma to malignant lesions of variable malignant potential. FNAC is major diagnostic tool and is of great relevance in head and neck lesions, including major salivary glands as they are easily accessible target sites. The aim of this study was to evaluate spectrum of salivary gland lesions with their clinical presentations and to study the cytomorphological features of various salivary gland lesions, and to evaluate its sensitivity and specificity of FNAC in salivary gland lesions whenever histopathology was available. Material and Methods: A total of 150 cases of salivary gland lesions were analysed both retrospectively and prospectively from January 2010- December 2015 at Department of Pathology, of a tertiary care medical college Hospital. Cyto-histopathological correlation was interpreted wherever available. Results: In the 150 cases thus analysed, the male to female ratio was 1.14:1. Parotid gland was involved in 73.34 %, submandibular gland in 23.33 %, and other minor salivary glands in 3.33% of patients. There were 57.33 % cases of neoplastic lesions and 42.67% cases of non-neoplastic lesions. Chronic sialadenitis (22.67%) was the commonest non neoplastic lesion. Pleomorphic adenoma (40.67%) was the commonest benign neoplasm and Mucoepidermoid carcinoma (9.33%) was the commonest malignant neoplasm. The overall sensitivity, specificity and diagnostic accuracy of FNAC for salivary gland lesions were 93.48 %, 100% and 94.23 %, respectively. Conclusion: Fine-needle aspiration cytology is a very useful diagnostic tool for superficial palpable tumors of salivary glands. It has high rates of sensitivity, specificity, positive predictive value in diagnosing salivary gland lesions and hence a valuable tool in the diagnosis and management of patients.

Heterotopic pancreas is a rare condition with a probable incidence of 1 per 500 upper abdominal operations. Findings are incidental and are usually asymptomatic. Heterotopic pancreas is seen at different sites in the gastrointestinal tract. A 62 year old male presented with complaints of epigastric pain, nausea, vomiting and constipation since 3 months. The diagnosis of malignancy was based upon the findings of abdominal ultrasonography, CECTabdomen and Upper G.I. endoscopy.

Natural products, such as plants extract, either as pure compounds or as standardized extracts, provide unlimited opportunities for new drug discoveries. The research is aimed to investigate the physicochemical properties and characterization of Eucalyptus camaldulensis leaves oil. The physicochemical were evaluated using the standard procedure and the oil was fund to be light yellow color having camphor like smell. The pH of the oil at 22oC was found to be 4.62 while the % oil yield, Optical activity, Refractive index at 27°C, Specific gravity at 27°C, were found to be 49.5±1.021, +34.2°, 1.4384 and 0.812 respectively. The absolute and kinematic viscosity of the leaves oil were 102.30 and 88.20 respectively and the Total acid number (TAN) in mg KOH/g, Iodine number and saponification number were 1.67, 109 and 110.00 respectively. GC-MS revealed the presence of 16 compounds representing 86.96 % of the total oil. The major component was 1,8-cineole (49.08 %), Eucalyptol (34.42) followed by α-pinene (23.90 %), while L-pinocarveol (8.98 %) and globulol (2.71) were the least components. Also α-terpineol, myrtenol, camphene and ciscarveol were present in the oil. The result revealed that Eucalyptus camaldulensis leave oil consist mostly of oxygenated monoterpenes that could be very useful for human, animals and industries, also the oil met the FOA/WHO standard of oils. Therefore, these essential oils could be considered as promising substances for development of new drugs. Hence it potential for medicinal and pharmacological uses.

Impaction is defined by Kuftinec and Shapira as a condition with embedded teeth in socket so that its eruption is prevented and will be locked in that position by either bone or adjacent teeth. Unlike isolated impactions multiple impactions may be due to the underlying syndromes or disorders. In cases where confusion exists in differential diagnosis additional examinations might become necessary to exclude systemic and metabolic disorders.

Oil Exploration in Nigeria has contributed greatly towards pollution of the environment especially in the Niger Delta region of the country where most of the oil wells are located. In the process of their operations which include; drilling, refining transportation etc., oil spillage occurs which pollutes land, air and water bodies. This results to the release of dangerous gases into the air. Properties of soils in the contaminated areas are highly affected leading to poor agricultural produce and alteration of geotechnical properties of soils which may adversely affect engineering construction works. This research work examines the effect of crude oil pollution on the geotechnical properties of clay soil. The clay soil was obtained from Engenni Ahoada L.G.A of Rivers, Nigeria. Soil samples were collected at a depth of approximately 2 meters below the ground surface and artificially polluted with crude oil in the ratio of 0%, 2%, 4%, 6%, 8%, 10%, 12%, and 14% of the dry weight of the soil. The samples were further subjected to various laboratory soil tests to determine their geotechnical properties. The results shows LL, PL, and PI increased from 31%, 20% and 11% at 0% contamination to 56%, 41% and 11% at 14%contamination. SPGR, BD, and MDD decreased from 2.48, 1.33g/cm3 and 1.74g/cm3 at 0% contamination to 1.14, 0.97g/cm3 and 1.35g/cm3 at 14% contamination. OMC increased from 15% at 0% contamination to 16.5% at 14% contamination. Thus, crude oil pollution affects the geotechnical properties of soil greatly.

Pre-eclampsia is one of the common complications of pregnancy and contributes significantly to high maternal and perinatal morbidity and mortality, especially in developing countries like Bangladesh. Objective: The aim of this study is to identify the risk factors and maternal and foetal outcomes of pre-eclampsia patients. Methods and Materials: This descriptive and observational study with data from the Department of Obstetrics and Gynaecology in Sir Salimullah Medical College and Mitford Hospital, Dhaka, during July 2011 to December 2011. Participants 123 pregnant women with pre-eclampsia included in the study. Main outcome measures Identify the risk factors associated with maternal & fetal complications, maternal and perinatal mortality & morbidity and incidence of pre-eclampsia. The patient with particular reference to age, parity, religion, occupation socioeconomic condition, gestational age, rapid weight gain, family history of hypertension and pre-eclampsia, obesity, new paternity, preexisting vascular disease, thrombophilias, previous history of pre-eclampsia, blurring of vision, pain in epigastrium, or pain in right upper quadrant, diabetes mellitus etc. Results: The incidence of pre-eclampsia is 4.3% and majority of the patients was found to be of 3rd decade. More than a half (51.2%) two third of the patient were primigravida. Maximum (65.9%) number was found in the gestational age group of 37 to 40 weeks. Lower abdominal pain 15.4%, Swelling of legs 15.4%, Headache 11.4%, less foetal movement 9.76% and Blurring of vision 8.13%. Mild pre-eclampsia was 44.0% and severe pre-eclampsia 56.0%. Fundal height had corresponded with 29 to 34 weeks in 42.0% patients, presentation was cephalic in 84.0%, fetal heart sounds was audible in 87.8% cases. The mean systolic and diastolic blood pressure was 164.76±9.34 mmHg and 101, 83±8.64 mmHg respectively and all patients had cephalic presentation. Fresh still birth was 3.5%, macerated still birth 1.8%, and Prematurity and IUGR were 7.0%. More than one third (36.4%) was low birth weight and male of female ratio of the babies were 1.1:1. According to APGAR score >7, were 51.5% and 81.8% during 1st and 5th minutes after birth respectively and 16.2% babies received neonatal resuscitation. Conclusion: Pre-eclampsia usually occurs in third trimester, and maternal outcome is better than fetal outcome although the maternal response to the treatment is in positive side.

Subfertility and unconstrained premature birth or unsuccessful labor is two types of conceptive disappointment. Subfertility influences about 10% to 15% of couples. Then again, the danger of fetus removal has been affirmed is about 15% to 20%. The differentiation among essential and auxiliary repetitive pregnancy loss can be made. Essential RPL is depicted as RPL without a past continuous pregnancy past 28 weeks' incubation, while auxiliary RPL is characterized as a scene of RPL after at least one past pregnancies advancing past 28 weeks' development. The main objective of this research is to find out the risk factors of recurrent pregnancy loss. The specific objectives are; to identify the origin of the pregnancy losses, to identify the probable therapeutic targets, and to provide recommendations regarding organization of care for couples faced with RPL. Total 60 samples were selected and the study duration was 3 years. After investigation, it was found that few factors, such as: age, psychological pressure, environmental and occupational exposure, chronic endometritis, smoking, genetic factors, and thrombophilia screening, uterine defects, were some of the risks of RPL. Multiple pregnancy loss can have a noteworthy mental cost for influenced couples, and numerous endeavors are being made to improve medicines and reduction the time expected to accomplish an effective pregnancy.

Introduction: Mitral prosthetic thrombosis (MPV) is a rare but dangerous complication. It is suspected by clinical examination; the diagnosis of MPV is made by trans-thoracic echocardiography and held by the trans-esophageal echocardiography; or a fluoroscopy which shows a lack of prosthesis opening. The treatment is based on the early establishment of anti-coagulation and surgical cure. The thrombolysis is an alternative therapy. Case report: We report the case of a 47-year-old man who undergone a mitroaortic mechanical prosthesis replacement 6 years ago. However, since a year, his INR has been sub therapeutic. He presented a 5 days history of a chest pain and dyspnea. A passing at the intensive care diagnosed a shock according to the cool extremities, sweats, tachypnea and low blood pressure. The ECG showed atrial fibrillation with complete left bundle block. An emergency TTE was performed and revealed a MPV with high transvalvular gradient, while the aortic prosthesis was functional. The left ventricle was dilated and globally hypo contractile; TEE was emergently performed and showed à stuck leaflet caused by thrombus with associated with a thrombus at the left auricle. Patient’s hemodynamic condition required a surgical cure with thrombectomy of the left atrium. Conclusions: Through this case we highlight the interest of echocardiography to diagnose the etiology of shock, and the importance of early management to avoid any complications.

Cerebral palsy is the commonest physical disability in childhood, occurring in 2.0 to 2.5 per 1000 live births [1] Cerebral palsy (CP), a neurodevelopment disorders, is usually associated with abnormalities of pregnancy, particularly 'birth asphyxia' and low birth weight [2]. In the present study all cases were males, mothers were more than 35 years, para4, and uncooked, illiterate and low socio economic status. They all had normal deliveries, were anemic, associated with severe pregnancy induced hypertension, preterm and extremely low birth weight and no genetic overlay Present study 5(0.05%) cases occurred out of 8500 deliveries. Cranial ultrasound imaging can describe patterns of neonatal brain damage in the low birth weight infant that are highly predictive of later cerebral palsy [3, 4].

This research was prompted by a reflection on the level of preparation and the way in which the course of Principles of Economic Theory is taught at the last grade of secondary education in Greece. Under the Greek system of access to tertiary education, this course determines, to a large extent, admission to university departments of economics. The research was conducted with students in a department of economics by investigating the degree of satisfaction from their high school preparation in relation to their decision to attend private supplementary teaching for the national admission exams to tertiary education. Additionally, there was an investigation into the choices of the educators as to the way in which the course in question was taught.

Dimethyl ether (DME) is used primarily as a propellant and a motor fuel alternative, (DME) is miscible with most organic solvents and has a high solubility in water. Recently, the use of (DME) as a fuel additive for diesel engines has been investigated due to its high volatility (desired for cold starting) and high cetane number of 55–60, with the advantage of high efficiency, and low exhaust emissions (no particulates, no Sulphur, and low NOx). Technical-quality (DME) is an alternative to liquefied petroleum gas (LPG). The production processes included catalytic dehydration of methanol in an adiabatic fixed-bed reactor and two columns product separations. In this study, the technological process for (DME) synthesis is simulated in Aspen Hysys V3.1 based on the combined parameters of the reaction dynamic model for methanol dehydration reaction, the improved NRTL model of the liquid phase, the PR model of vapor phase was selected as the fluid package as it is able to handle selected pure components (methanol, water and dimethyl ether). The equilibrium reaction was selected to describe conversion of methanol to DME reaction and it is about 80%. A feasibility study and design of a plant producing 99.9 wt% Dimethyl ether (DME). The plant is designed which is capable of producing 50,000 metric tons of (DME) per year via the catalytic dehydration of methanol over an acid zeolite catalyst.

The Integrated Management System (IMS) could consider as one of the most important factors that eases the process of integrating many quality and safety management systems into one system to facilitate the implementation of the systems requirements. Jubail Technical Institute (JTI) obtained ISO 9001 certificate in 2015, followed by several certificates such as ISO 22000, OHSAS 18001 and ISO 10015 respectively. These certificates and others made it necessary for JTI to unify efforts and increase the effectiveness of meeting the requirements of these systems. The used tool for achieving these purposes was the MISWEB which is an internal website that organizes the integration of quality and safety management systems in IMS and provides many internal services. Throughout the MISWEB, JTI has been developed many electronic procedures, documents and forms to communicate them for the sake of increasing the use of forms, procedures. In this case study, the impact of IMS (ISO 9001, ISO 22000, OHSAS 18001 and ISO 10015) through MISWEB was measured. Specifically, the satisfaction rates of the faculty members, and the administrative staff on the procedures, forms and documents of IMS. Many tools and methods such as the tables, figures, and shape in addition to the Likert scale for the surveys were used to illustrate the impact of the IMS. A group of faculty members and the administrative staff have been surveyed over five years. The number of those samples from the two surveys were (152, 159, 125, 120, 82) for the years (2015, 2016, 2017, 2018, 2019) respectively. The analysis of data went through several steps such as the average scores and the range was from (3.87 to 4.45) out of 5. Moreover, the standard deviation of the data was measured and ranged between (0.67 and 1.08). The results of the Cronbach Alpha tests reached (0.89). The overall satisfaction rate of the faculty members and administrative staff on the procedures, forms and documents in the IMS at the MISWEB website were (86%). The satisfaction rate of the faculty members on the clarity of responsibilities in the procedures and clarity of procedures were (93%). While, the satisfaction rate of administrative staff on the clarity of procedures and forms, the extent of updating these forms, the suitability of these procedures and forms is equivalent to (80%). These results have led to improving the integrated management system. As well as enhance the work of MISWEB and pursue the satisfaction of faculty members and administrative staff to ensure high-quality services.
