Abstract. We compare three well known methods for solving the PDEs such as Finite Difference Method (FDM), Spectral Method, Wavelet Galerkin Method (WGM). We test all these methods on Advection Equation and Klein-Gordon Equation.We plot comparison and error graphs using MATLAB.
In spite of wide prevalence, deliberate self-injury in the oro-facial region is rarely reported in literature. It is also associated with misinterpretation related to ‘attention seeking’ or ‘mental health crises’ leading to deficient understanding of this phenomenon. A literature review was performed using online search databases looking at dermatitis artefacta in the head and neck region. A case of a patient who was seen in our unit is also presented to give important insights into this condition. In total, 54 cases from 15 publications were included in this observational study. Female gender predilection was notable (4:1) with an average presenting age of 30 years. The face itself was more frequently injured, along with the neck and scalp. Only one-third (34%) of the patients were known to have psychiatric conditions, such as depressive and personality disorders. Dermatitis artefacta is a well-known skin condition caused by deliberate self-injury. It is a complex entity that is frequently unrecognized and underdiagnosed. CPD/Clinical Relevance: Understanding dermatitis artefacta will facilitate correct diagnosis and improve patient care.
Introduction: Carcinoma of the breast is the leading cause of death in women due to malignancy. Approximately 1,000,000 cases occur worldwide annually. Evaluation of the breast masses is of utmost important for its timely management. Fine needle aspiration cytology is a simple and reliable diagnostic method. The present study aim ED to determine the diagnostic efficacy of the fine needle aspiration cytology along with evaluating the causes of false negative and false positive in breast cytology. Materials and Methods: The present retrospective study was conducted in G K General Hospital, Bhuj for a period of one year. Cases in which follow up histopathology was available were only included in the present study. A total 52 cases were included in the study. Results: Fine needle aspiration cytology findings and histopathology diagnoses were correlated. Statistical analysis was done. Out of the 52 cases, only one false positive and one false negative case was found. Hence, the sensitivity of the study was 98% and the positive predictive value was also 98%. Conclusion: Fine needle aspiration cytology is a reliable diagnostic method to evaluate the breast masses. A high sensitivity and a high positive predictive value proved that a positive fine needle aspiration cytology in the breast correlates very well with the corresponding final histopathology reports.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
