Sensitivity and specificity Essays

Derek’s shoulder to 90o followed by horizontal adduction. According to Chronopoulos et al, the Cross-body adduction test had the greatest sensitivity for diagnosing chronic acromioclavicular injuries

INTRODUCTION As a part of the requirements for the Introduction to Hospitality Law subject, I am required to do a research and write an essay that provides evidence of the importance of knowledge of laws in the Hospitality Industry and five (5) key legal issues that affect this industry. CONTENT Hospitality law is related to the concept of legal liability and it is meant to legally protect both hosts and guests. Hospitality law covers many different type of businesses while the most common

Alvarado score 7 as cutoff value yielded sensitivity of 76.19%, specificity of 59.46%, positive predictive value of 76.19%, negative predictive value of 56.46% with overall accuracy of 70% while Alvarado cutoff 6 had a sensitivity of 87.30, specificity of 48.65, positive predictive value of 74.32, negative predictive value of 69.23% and overall accuracy of 73%.In comparison to other authors, we find out that Alvarado score below 5 has a very high sensitivity to rule out appendicitis up to 99% as described

including borderline tumors, from healthy control samples. Double-blind tests showed 100% sensitivity and 97.5% specificity. Moreover, the odor of ovarian carcinomas seems to differ from those of other gynecological malignances such cervical, endometrial, and vulvar carcinomas.6 Overall sensitivity of canine scent detection compared to biopsy confirmed conventional diagnosis was 0.99. 95% (CI) overall specificity 99%. Ordinary household dogs with only basic, behavioral puppy training were trained to

the prevalence is the probability to find an individual aged 5 to 15 years old that already has gone through his o her growth spurt, being 11% and 26% respectively. Sensitivity, which is the ability to identify a post pubertal growth spurt individual when having a dental stage F, G or H is 87% for females and 97.1% for males. Specificity, the ability to identify that has not gone through pubertal growth spurt yet when having a dental stage A to E, is 82.9% for females and 72.3% for

the physician collect cells from the cervix he then smears them on a microscope slide and applies a fixative. In general, the slide is sent to a laboratory for evaluation. From studies conventional cytology report is very high with: • sensitivity 72% • specificity 94%” (17) 2.5.1.1.2 Liquid-based cytology (LBC) testing This is a method based on placing the sample into a bottle containing a liquid medium that preserves the cells. “There are two types of the technique which are the Sure-Path (TriPath

This course has expanded our knowledge on the causation and effects of numerous diseases that impact the field of epidemiology. A disease that deserves utmost attention is Chlamydia as it severely affects women. This case study is enabling us to explore the effectiveness and efficiency of tests that may be used to curb the problem of this sexually transmitted disease. Chlamydia is very prevalent globally and it is feared by many and yet still there are so many unreported cases of the disease. According

Criteria for considering studies for this review We included any type of study design with data collection. There was no age restriction and we included studies looking at patients presenting with fever who were subsequently tested for dengue using both the Tourniquet test and Enzyme-Linked Immunosorbent Assay (ELISA). For this review: Dengue fever was considered: “Fever along with at least 2 of the following: headache, retroorbital pain, muscle pain, joint pain and rash. May be accompanied by

Airway management, including the ability to intubate, is a basic skill required in the repertoire of an anaesthesiologist. Inability to maintain a patent airway results in inadequate ventilation and oxygenation leading to hypoxic brain damage and death. The incidence of difficult intubation in surgical patients undergoing general anaesthesia is estimated to be approximately 1-18% whereas that of failure to intubate is 0.05 -0.35%.(1,2,3) Various methods have been used for prediction of difficult

The sensitivity and specificity of mammography and sonography was compared with that of mammography and sono-elastography Statistical analysis was performed for all variables and sensitivity, specificity, positive and negative predictive values were calculated. Results: Of the 60 lesions 28 appeared benign and 32 appeared malignant on mammography and ultrasonography

evaluate the accuracy, sensitivity and specificity of CT scan in diagnosing bronchogenic carcinoma taking histopathology as the gold standard. OPERATIONAL DEFINITION Bronchogenic Carcinoma All those patients who had a pulmonary lesion on X ray along with history of symptoms like hemoptysis, weight loss, and recurrent pleural effusion etc. will be taken as possible cases of bronchogenic carcinoma. Diagnostic Accuracy of the investigation will be assessed via sensitivity, specificity, positive predictive

They are typically applicable to patients six years old and older showing a 98.5 average sensitivity for that population and exhibiting a very low rate of false negatives. The specificity is moderate: 40%. The OAR has been recognize to reduce the use of x-rays up to 30%. Please note some studies support the use of the OAR for patients as young as 2 y/o (Plint, Bulloch, Osmond, Stiell, Dunlap

diagnosis. The sensitivity of CAM has varied from 46% to 100% with lower sensitivities reported when CAM was used by nurses or research assistants. 23-25 The specificity of CAM has varied from 63% to 100%, with lower specificity in presence of psychiatric comorbidity. 41 It is one the very few instruments which have been translated in 10 languages and has been widely used in research. 22, 24 One Indian study observed that the CAM is a useful screening method with high sensitivity for diagnosis of

second article that was reviewed came for National Guideline Clearing house (NGC, 2012). The methods used to analyze the evidence were review of published meta-analyses and systematic review. The major outcomes considered in the study were sensitivity, specificity, and reliability of screening tools, risk factors for falls and fall rates. There were numerous recommendations that were recommended to reduce and prevent falls among the elderly population. However the best practice in fall reduction includes

The cuff-leak test for as a predictor for extubation: Fisher and Raper(11) (1992) tested the leak among 62 patients with upper airway obstruction. They were able to extubate all patients with a cuff leak. Two patients extubated without cuff leak required reintubation and in five patients who repeatedly failed the test, tracheostomy was performed. Subsequently, they extubated 10 patients who were stable on spontaneous ventilation and did not have cuff leak; three later required tracheostomy and seven

Used alone, the Mallampati oropharyngeal view, and thyromental and sternomental distances were associated with poor sensitivity, specificity and positive predictive values. Combining the Mallampati Class III or IV with either a thyromental distance <12.5cm decreased the sensitivity (from 40 to 25 and 20%, respectively), but maintained a negative predictive value of 93%. The specificity and positive predictive values increased from 89 and 27% respectively for Mallampati alone to 100%.The findings suggest

However, studies have proven that it is one of the most sensitive RDT available in the market. This study will also use the relatively new QuantuMDx device, the Q-POC which uses advanced technology to diagnose malaria, determine species and drug sensitivity. It will be the first time this device is used in Cameroon and to the best of our knowledge the first time it is being tested in central and west Africa. 4.3. Potential

Introduction Pre-eclampsia, a disease characterized by widespread maternal endothelial dysfunction, hypertension, and proteinuria, is a leading contributor of maternal and fetal morbidity and mortality in the world. This pregnancy-specific disease is complicating about two to eight percent of pregnancies. Therefore, it is important to identify women at risk of developing pre-eclampsia in order to reduce complications and to develop possible treatment modalities. 1,2,3 Preeclampsia has a complex pathophysiology

diseases because morphological appearance may not be changed in early stage even though the functions have already been altered [5]. Hence, early diagnosis and treatment can be provided, thereby improving prognosis. Adding to that, since the sensitivity of bone scintigraphy is governed by the level of osteoblastic activities, osteoblastic metastases may show a higher uptake of tracers and appear “hot”; whereas osteoclastic metastases may demonstrate a lower uptake of tracers and appear “cold”.

A STUDY OF VALIDITY OF HAEMATOLOGICAL PARAMETERS IN THE DIAGNOSIS OF NEONATAL SEPSIS Manoj Barman &Barnali Das IDENTIFY AN ISSUE THAT IS RELATED TO EDUCATIONAL STATISTICS In this prospective study, infants were enrolled if there were predisposing perinatal factors or if there was clinical suspicion of sepsis.The study included three groups: Group 1—infants with sepsis with positive blood cultures, Group 2—infants with probable infection with strong clinical history but negative blood cultures
