Detection of a Rheumatic Factor (RF,) Anti- Cyclic Citrullinated Peptides (Anti CCP) Antibodies and C- Reactive Protein (CRP) in Diagnosis and Prognosis of Rheumatoid Arthritis

Introduction: Rheumatoid arthritis ( RA)is an autoimmune and inflammatory disease. It is characterized by arthrosynovitis with resultant joint destruction . So, an early clinical diagnosis along with simple serological tests like anti CCP antibodies, C –reactive protein ( CRP) and Rheumatoid factor (RF) play an important role .An attempt was made to study and compare these parameters in OPD and IPD RA patients in our hospital setup, VMMC and Safdarjung Hospital , New Delhi. Aims and Objectives: To study the role of RF , Anti-CCP antibodies and CRP in early detection and prognosis of Rheu- matoid arthritis. Materials and Methods: A Total of 440 samples were studied from January 2018 to December 2020 (3years). Correlation between Rheumatoid factor(RF) ,anti CCP antibodies and CRP in suspected RA patients from various departments like PMR , Orthopaedics , Medicine, Obstetrics and Gynaecology and Paediatrics was attempted. RF and CRP was performed using latex agglutination test and anti CCP antibody by ELISA. Results and Conclusion: Of 440 samples tested, all the factors were positive in 87 patients . Anti CCP and RF alone was seen in 32 patients. RF and CRP positive in 49 patients, RF alone in 22 patients. In 250 patients all the tests were negative. So, Anti CCP along with RF and CRP showed a better positive predictive value in patients of Rheumatoid arthritis. But positivity of these parameters even in patients who lack sign and symptoms also aids in better diagnosis, treatment and prognosis.

Demographic and Socioeconomic Influence on Antenatal Care Utilization Among Pregnant Women in Wa Municipality of The Upper West Region of Ghana

Introduction: It remains unclear if benefits of antenatal care can be attributed to the amount and content of care or to uncontrolled risk factors that might also affect its use. An understanding of the factors influencing antenatal care is still a challenge because the pathways through which the effects are obtained remain elusive. Objective: The study examined the factor influencing antenatal care utilisation in the Wa Municipality. Methodology and Data: The study employed a retrospective cohort design. The probability proportionate to size sampling was used to select the sub-district health catchment facilities, while the systematic random sampling was used to select respondents. Data was collected from 353 women based on the status of Antenatal care utilization. Results: The results suggest that the educational status, maternal knowledge on adequacy of four or more antenatal care, score for general services received, number of tetanus toxoid doses received and anaemia status at Antenatal care registration were significant predictors to adequate antenatal care utilization. Conclusion: The study further found that women who had anaemia at antenatal care registration, General quality of received women received at antenatal care, level of Tetanus doses as well as knowledge on the adequacy of antenatal care were significant factors that influence antenatal care usage among reproductive aged women in the Wa municipality. The implication is that, attention should be drawn by health management authorities to ensure an improvement in the coverage antenatal care in Wa Municipal while health staff are encouraged to enforce to the latter all due protocols in the discharge of their duties at antenatal care utilisation in Ghana

A Diagnostic Dilemma of Pancreatic Adenocarcinoma: The Duct Cut-off Sign

Pancreatic cancer carries one of the worst prognoses in the United States. It is the fourth leading cause of cancer-related death in the United States and second after colorectal cancer in digestive system cancer-related death. Early detection is the key to improving its prognosis. Surgical resection is the only curative treatment, but even after margin-negative resection, the 5-year survival rate is still 30%. The following case presents a fascinating diagnosis of pancreatic cancer. Despite an initial diagnosis of pancreatitis, negative cytology, tumor markers, and imaging suggestive of intraductal papillary mucinous neoplasm (IPMN), this patient underwent surgical resection that later revealed pancreatic adenocarcinoma of the tail. This article highlights certain imaging modalities and characteristics that are essential in the diagnosis of pancreatic adenocarcinoma, in an effort to guide management of similar cases, with hope it leads to better outcomes.

Immunological Analysis of Active Tuberculosis Infection in Children and Adolescents

The latent tuberculosis infection worldwide is determined by about 1.7 billion people. Identification of latent tuberculosis infection and prevention of the development of the disease is one of the highest priority tasks in the global radical reduc- tion of the burden of tuberculosis. The research is devoted to the study of the effectiveness of cellular and humoral anti- gen-specific immunological methods for determining the initial signs of tuberculosis infection activity when examining children and adolescents with a latent form of this infection. Cellular immunological reactions in contrast to the determi- nation of specific antibodies of blood serum using the recombinant specific protein ESAT-6-CFP-10, were not sufficiently effective in differentiating active and latent infections. Determination of antibodies to the ESAT-6-CFP-10 protein with analysis of the specific activity criterion and determina- tion of an increased concentration of neopterin up to 9 nM/L in blood plasma samples made it possible to reveal signs of tuberculosis infection activity. These results have been confirmed by the results of chest computed tomography of children and adolescents with the determination tuberculosis of intrathoracic lymph nodes or small intrapulmonary (2-5 mm) intrapulmonary foci, including those with signs of calcification.

Dengue Hemorrhagic Fever and Rapidly Progressive Glomerulonephritis (RPGN): A New Persuasion

Dengue is a prevalent arthropod-borne viral disease in tropical and subtropical areas of the globe. Dengue clinical manifestations include asymptomatic infections; undifferentiated fever; dengue fever, which is characterized by fever, headache, retro orbital pain, myalgia, and arthralgia; and a severe form of the disease denominated dengue hemorrhagic fever/dengue shock syndrome, characterized by hemoconcentration, thrombocytopenia, and bleeding tendency. However, atypical manifestations, such as liver, central nervous system, and cardiac involvement, have been increasingly reported called expanded dengue syndrome. The renal complications of dengue virus infection cover a wide spectrum of manifestations from acute kidney injury to glomerular injury with nephritic/nephrotic syndrome. Majority of cases remain symptom free and show full recovery. We report a 55 years old lady with atypical and rare presentation of dengue disease marked by rapidly progressive glomerulonephritis. Condition improved after initial 5 days pulse methylprednisolone followed by oral prednisolone therapy and mycophenolate mofetil. The main mechanism of dengue glomerulonephritis is still unknown though both direct viral infection and immune mediated damage have been suggested to be the cause. To avoid otherwise preventable morbidity and mortality, physicians should have a high index of suspicion for renal complications in patients with dengue illness and should manage this accordingly

Progressive Supranuclear Palsy with Classic Radiological Signs: A Case Report and Literature Review

Progressive supranuclear palsy (PSP) is a rare neurodegenerative parkinsonian syndrome with distinct clinical features which tends to be progressive, causing vertical supranuclear gaze palsy, frontal lobe cognitive decline, postural instability and progressive axial rigidity. Clinical examination typically reveals ocular motor dysfunction including restricted vertical gaze, slow vertical saccades and “eyelid opening apraxia” with intact vestibule ocular reflex. PSP falls under the rubric of Parkinsonism plus syndromes that are a group of heterogeneous degenerative neurological disorders that differ from the classical idiopathic Parkinson’s disease. PSP is often underreported, making it important for clinicians to be aware of this disorder. Here we report a case of PSP, which presented primarily with speech disturbances and recurrent falls due to postural instability. On investigating, the magnetic resonance imaging (MRI) revealed a classical sign diagnostic of PSP. This teaching case report describes management and prognosis of the disease

A Java Software for Randomized Phase II Clinical Cancer Trial Designs

Traditionally, a typical phase II trial has been conducted using a single-arm design recruiting patients only to the experimental therapy to be compared with a historical control. Due to a small sample size and heterogeneity of patient population, the patient characteristics of the patients in a new phase II trial is often different from that of the selected historical control, so that the single-arm phase II trial may lead to biased conclusions. A randomized phase II trial can resolve such problems by randomizing patients between an experimental arm and a control arm. We propose a software package for designing and analyzing randomized phase II trials. We develop a user-friendly Java software that will help us find optimal two-stage phase II trial designs. Although the programs accommodate trial designs based on various statistical methods and different types of early stopping rules, the main part of our paper is focused on randomized phase II trials based on Fisher’s exact test with futility and superiority early stopping values. If users enter input parameter values, the software generates a graphical output displaying all efficient two-stage designs. Minimax, optimal, and admissible designs are highlighted as good designs, but users can select any of the displayed designs. When the circle representing a design is clicked, all the specifics of the selected design are displayed. Fisher’s test is an exact method whose critical values depend on the total number of responders from two arms. So, the computations required to search for optimal randomized multi-stage phase II trial designs based on Fisher’s exact test is very heavy. By using efficient algorithms, our software provides output at almost real time speed

Confirmation Bias and Restorative Justice in The Setting of a Missed Diagnosis

One factor underlying medical errors in “confirmation bias,” the tendency to interpret new evidence as confirmation of one’s existing beliefs or theories. When a medical error occurs, the physician has a moral duty to examine the factors which lead to its occurrence, to discuss these factors with the patient who suffered the error, and to perform their due diligence to prevent the error from occurring again. Restorative Justice is a form of collaborative decisionmaking including all parties involved in a precipitating event, including the perpetrators, victims, and stakeholders. We report on a case in which confirmation bias played a major role in misdiagnosis followed by the application of Restorative Justice principles to address the consequent mistrust between the physician and patient.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
