  Nodular goiter is a clinicopathological entity characterized by an increased volume of the thyroid gland with formation of nodules. Nodular goiter occurs due to repeated hyperstimulation of thyroid gland due to iodine deficiency, goitrogens, anti-thyroid drugs and genetic defects. Nodular goiter can have different complications which include tracheal compression, retrosternal extension, malignancy and secondary thyrotoxicosis. The present study attempted to study clinical presentation of nodular goiter and to determine the incidence of thyroid cancer in solitary nodular goiter and multinodular goiter in patients admitted in surgery ward of IGMCRI, Puducherry. Retrospective record-based study and single-center study was carried out between January-2011 to December-2019 on consecutive 230 patients admitted in surgery ward with nodular goiter and age above 18 years. Ethics approval was obtained from Institute Ethics Committee (IEC) of IGMCRI. Demographic variables (age and gender), Diagnosis, FNAC, BIOPSY and Carcinoma frequency was assessed in the present study. Data was entered in Microsoft Excel spreadsheet and the data underwent analysis using descriptive statistics involving tables, graphs and bar diagrams. In our study, majority of the study participants (90.4%) belonged to female gender. Maximum patient cases (34.78%) belonged to adult range within 31-40 years.

  Background: Acute appendicitis is a common and sometimes confusing cause of acute abdomen in all age groups. Diagnosis of appendicitis can be difficult, occasionally taxing the diagnostic skills of even the most experienced surgeon. Despite the increased use of USG, CT, the rate of misdiagnosis of appendicitis has remained the same (15.3%). To evaluate the usefulness of the Alvarado score as a simple and reliable tool in preoperative diagnosis of acute appendicitis.Methods: This retrospective study conducted on 97 cases includes all patients who were admitted with a clinical diagnosis of acute appendicitis for a period of one year from February 2019 to January 2020 at IGMCRI Pondicherry with clinical suspicions of acute appendicitis were included in the study. The modified scoring system is based on 3 signs, 3 symptoms, and 1 laboratory finding. The patient was classified as males, females, and children (<12 years). These were further grouped based on the scores 7-9, 5-6, and <5.Results: A total of 80 patients with a score of 7-9 and 5-6 were operated on. Among males with a score of 7-9, 35 patients were operated and 34 were found to have an inflamed appendix. Females with scores 7-9, 16 were operated and 11 were found to have an inflamed appendix.Conclusions: Alvarado scores significantly reduce the number of negative laparotomies without increasing the overall rate of appendicular perforation. It is very effective in men and children but diagnostic laparoscopy or ultrasonography is advised to minimize the high false-negative rate in women.

• Tarski on the Concept of Truth

  Oxford University Press eBooks · 2018-09-07 · 2 citations

  book1st authorCorresponding

  Alfred Tarski’s work on truth has been so central to the discourse on truth that most coming to it for the first time have probably already heard a great deal about what is said there. Unfortunately, since the work is largely technical and Tarski was only tangentially philosophical, a certain incautious assimilation dominates many philosophical discussions of Tarski’s ideas, and so, examining Tarski on the concept of truth is in many ways an act of unlearning. This chapter will focus on key ideas in Tarski’s work that have had a lasting impact: T-sentence, Convention T, Tarskian truth definition, and Tarski’s general limiting theses on the expressibility and definability of truth. Though these ideas are familiar in name, the chapter seeks to uncover and remove certain widespread misunderstandings. Tarski’s name also features prominently in discussions of the liar paradox, so we will discuss Tarski’s misunderstood connection to this ancient puzzle.

  Abstract The problem of negative existentials is one of the classic problems in philosophy of language. Latter-day developments in semantics resolved this problem without our help, but due to accidents of history no one noticed.
