Background: Owing to the use of tobacco and the consumption of alcohol and adulterated food, worldwide cancer incidence is increasing at an alarming and frightening rate. Since the last decade of the twentieth century, lung can-cer has been the most common cancer type. This study aimed to determine the global status of lung cancer and to evaluate the use of computational methods in the early detection of lung cancer. Methods: We used lung cancer data from the United Kingdom (UK), the United States (US), India, and Egypt. For statistical analysis, we used incidence and mortality as well as survival rates to better understand the critical state of lung cancer. Results: In the UK and the US, we found a significant decrease in lung cancer mortalities in the period of 1990–2014, whereas, in India and Egypt, such a decrease was not much promising. Additionally, we observed that, in the UK and the US, the survival rates of women with lung cancer were higher than those of men. We observed that the data min-ing and evolutionary algorithms were efcient in lung cancer detection. Conclusions: Our findings provide an inclusive understanding of the incidences, mortalities, and survival rates of lung cancer in the UK, the US, India, and Egypt. The combined use of data mining and evolutionary algorithm can be efcient in lung cancer detection.

Methods: In a double-blinded setup, 124 patients randomly received either of the following injections: 2% lidocaine with 1:80,000 epinephrine, 2% lidocaine with 1:80,000 epinephrine mixed with 2 mg dexamethasone, or plain 2% lidocaine mixed with 2 mg dexamethasone, which were injected as a primary IANB. Ten minutes after injection, patients with profound lip numbness underwent electric and thermal pulp sensibility tests. Patients who responded positively to the tests were categorized as “failed” anesthesia and received supplemental anesthesia. The remaining patients underwent endodontic treatment using a rubber dam. Anesthetic success was defined as “no pain or faint/weak/mild pain” during endodontic access preparation and instrumentation (HP visual analog scale score < 55 mm). The effect of the anesthetic solutions on the maximum change in heart rate was also evaluated. The Pearson chi-square test at 5% and 1% significance was used to analyze anesthetic success rates. Results: The 2% lidocaine with 1:80,000 epinephrine, 2% lidocaine with 1:80,000 epinephrine mixed with 2 mg dexamethasone, and plain 2% lidocaine mixed with 2 mg dexamethasone groups had anesthetic success rates of 34%, 59%, and 29%, respectively. The addition of dexamethasone resulted in significantly better results (P < 0.001, χ 2 = 9.07, df = 2). Conclusions The addition of dexamethasone to 2% lidocaine with epinephrine, administered as an IANB, can improve the anesthetic success rates during the endodontic management of symptomatic mandibular molars with irreversible pulpitis.

Background: Congenital hernia of the umbilical cord (CHUC) is the rarest type of anterior abdominal wall defect, in which an intact umbilical ring is always present and viscera pass through the base of normal-looking umbilicus. Objectives: This study was conducted to document the intraoperative findings and postoperative outcomes of patients with congenital hernia of the umbilical cord up to discharge from a tertiary care center. Methods: This study was a retrospective observational study conducted for two years (August 2020 to July 2022) in the Department of Pediatric Surgery, at the tertiary health care center of UP, India. Results: During this two-year duration, a total of 10 cases with CHUC were seen in our department and were surgically managed. In this study, out of these 10 patients (male 7 and female 3), eight had normal gastrointestinal tract, one had accessory liver tissue on thin pedicle, and one had features of gangrenous bowel. Of these 10 cases, three patients developed postsurgical complications in which two patients developed superficial wound infection while one developed wound dehiscence. No mortality was noted. Conclusions Congenital hernia of the umbilical cord induces stress on parents and relatives. In this study, we conclude that the majority of cases had normal gastrointestinal tract and had no serious postoperative complications up to discharge.
