Citizen scientists with health interests have rapidly increased efforts to conduct their own health studies on themselves and in their communities, giving rise to a new transdisciplinary field of citizen health science. This science leverages long-standing traditions of single case or N-of-1 studies in psychology and also finds influential roots in the history of self-experimentation in health and medicine. These studies frequently incorporate new digital tools such as smartphone tracking and many other mobile health or "mHealth" devices. Citizen health scientists also tend to operate in social networks of people working to maintain or improve their health, increasing the complexity and richness of opportunities tied to this new platform. Population data scientists are well-positioned to seek new ways to derive scientific inferences from data generated in citizen health science projects. This paper provides an overview of citizen health science for population data scientists, including basic definitions, historical foundations, current challenges and opportunities, and future directions.Oral and maxillofacial infection is a common complication in patients undergoing chemotherapy. The treatment of oral diseases in such patients differs from that administered to healthy patients. This paper reports a case of acute osteomyelitis of odontogenic origin following a recent chemotherapy session. The patient's condition was life-threatening because of neutropenic fever and sepsis that developed during the inpatient supportive care. However, the patient showed prompt recovery within 40 days following the use of appropriate antibiotics and routine dressing, without the requirement for surgical treatment, except tooth extraction. As seen in this case, patients undergoing chemotherapy are more susceptible to rapid progression of infections in the oral and maxillofacial areas. Therefore, accurate diagnosis through prompt clinical and radiological examination, identification of the extent of infection, and assessment of the patient's immune system are crucial for favorable outcomes. It is also necessary to eliminate the source of infection through appropriate administration of antibiotics.  https://www.selleckchem.com/products/sw-100.html  In particular, a broad-spectrum antibiotic with anti-pneumococcal activity is essential. Proper antibiotic administration and wound dressing are essential for infection control. Furthermore, close consultation with a hemato-oncologist is necessary for effective infection management based on the professional evaluation of patients' immune mechanisms.
  Placement of full-coverage restorations such as stainless steel crowns (SSCs) for pulpectomy treated primary molars is essential for successful outcomes. The tooth preparation process for SSCs can cause discomfort to gingival tissues since the crown should be seated 1 mm subgingivally. The purpose of this prospective trial was to compare the effectiveness of subgingival and transmucosal application of topical anesthetics on dental pain during SSC tooth preparation among 6- to 8-year-old children.
 
  A consecutive sample of 27 children, aged 6-8 years, who required an SSC after pulp therapy in primary molars were randomly divided into three groups. Group A received infiltration anesthesia before tooth preparation for SSC placement, whereas in Group B and C, only topical anesthesia was applied subgingivally and transmucosally. Wong-Bakers Faces pain rating scale (WBFPS) scores were recorded after tooth preparation. Faces, Legs, Activity, Cry and Consolability (FLACC) scores were evaluated by two blinded and casal application of topical anesthesia did not reduce discomfort when compared to the other two interventions.
  Palatal injection of local anesthetics is the most painful injection. To obviate the need for palatal injections, local anesthetic agents with diffusibility are being investigated. Hence the present study was designed to analyze the anesthetic efficacy of 2% lidocaine hydrochloride (HCl) with 1100,000 adrenaline and 4% articaine hydrochloride (HCl) with 1100,000 adrenaline using single buccal infiltration for the extraction of maxillary premolars.
 
  A prospective, double-blind, crossover, randomized clinical study was performed on 60 consecutive systemically healthy patients with an age range of 15-30 years, requiring extraction of asymptomatic bilateral maxillary premolars for orthodontic purposes. They received 1ml buccal infiltration of 4% articaine HCl with 1100,000 adrenaline on one side and 2% lidocaine HCl with 1100,000 adrenaline on the other side. The extraction procedure on either side was scheduled 14 days apart. Parameters assessed were the time of onset of anesthesia, intraoperative discomfort, hemodynamic parameters, and the duration of analgesia. Analysis of the data was done using the Mann-Whitney test, the Wilcoxon test, the Kruskal-Wallis ANOVA test, and the chi-square test. Statistical significance was established at P < 0.05.
 
  Articaine showed a faster time of onset and longer duration of analgesia than lidocaine. However, the difference in the intraoperative discomfort and hemodynamic parameters was statistically insignificant.
 
  Within the limitations of the study, it can be concluded that the extraction of maxillary premolars can be performed with a single buccal infiltration of 2% lidocaine HCl with 1100,000 adrenaline, which is one of the most commonly used local anesthetic agent.

  The most frequent complication of nasotracheal intubation (NTI) is epistaxis. Epinephrine nasal gauze packing has been used conventionally as a pre-treatment for reducing epistaxis, but it carries a disadvantage of pain and anxiety in patients. However, xylometazoline drops are easier to administer and more convenient for patients. We aimed at comparing the effectiveness of xylometazoline drops and epinephrine merocele packing in reducing bleeding and postoperative complications in our population.
 
  Our study enrolled 120 patients in a double-blind randomized controlled trial. We randomly allocated ASA1 or 2 adult patients into 2 groups Group X and Group E. Group X received 0.1% xylometazoline nasal drops, and epinephrine (110,000) merocele nasal packing was used in Group E. The primary outcome was the incidence of bleeding during NTI; the severity of bleeding, navigability, bleeding during extubation, and postoperative complications were secondary outcomes. We used IBM SPSS and Minitab software for statistical analysis, and P < 0.
