[PMID: 38138242 PMCID: PMC10744680 DOI: 10.3390/medicina59122139] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 12/06/2023] [Accepted: 12/07/2023] [Indexed: 12/24/2023]
Abstract
Thermography provides non-invasive, radiation-free diagnostic imaging. Despite the extensive literature on medical thermography, a comprehensive overview of current applications is lacking. Hence, the aim of this scoping review is to identify the medical applications of passive infrared thermography and to catalogue the technical and environmental modalities. The diagnostic performance of thermography and the existence of specific reference data are evaluated, and research gaps and future tasks identified. The entire review process followed the Joanna Briggs Institute (JBI) approach and the results are reported according to PRISMA-ScR guidelines. The scoping review protocol is registered at the Open Science Framework (OSF). PubMed, CENTRAL, Embase, Web of Science, OpenGrey, OSF, and PROSPERO were searched using pretested search strategies based on the Population, Concept, Context (PCC) approach. According to the eligibility criteria, references were screened by two researchers independently. Seventy-two research articles were identified describing screening, diagnostic, or monitoring studies investigating the potential of thermography in a total of 17,314 participants within 38 different health conditions across 13 therapeutic areas. The use of several camera models from various manufacturers is described. These and other facts and figures are compiled and presented in a detailed, descriptive tabular and visual format. Thermography offers promising diagnostic capabilities, alone or in addition to conventional methods.

Luksaite-Lukste R, Kliokyte R, Samuilis A, Jasiunas E, Luksta M, Strupas K, Poskus T. Conditional CT Strategy-An Effective Tool to Reduce Negative Appendectomy Rate and the Overuse of the CT. J Clin Med 2021; 10:jcm10112456. [PMID: 34206008 PMCID: PMC8198775 DOI: 10.3390/jcm10112456] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Revised: 05/11/2021] [Accepted: 05/25/2021] [Indexed: 12/29/2022] Open
Abstract
(1) Background: Diagnosis of acute appendicitis (AA) remains challenging; either computed tomography (CT) is universally used or negative appendectomy rates of up to 30% are reported. Transabdominal ultrasound (TUS) as the first-choice imaging modality might be useful in adult patients to reduce the need for CT scans while maintaining low negative appendectomy (NA) rates. The aim of this study was to report the results of the conditional CT strategy for the diagnosis of acute appendicitis. (2) Methods: All patients suspected of acute appendicitis were prospectively registered from 1 January 2016 to 31 December 2018. Data on their clinical, radiological and surgical outcomes are presented. (3) Results: A total of 1855 patients were enrolled in our study: 1206 (65.0%) were women, 649 (35.0%) were men, and the median age was 34 years (IQR, 24.5–51). TUS was performed in 1851 (99.8%) patients, and CT in 463 (25.0%) patients. Appendices were not visualized on TUS in 1320 patients (71.3%). Furthermore, 172 (37.1%) of 463 CTs were diagnosed with AA, 42 (9.1%) CTs revealed alternative emergency diagnosis and 249 (53.8%) CTs were normal. Overall, 519 (28.0%) patients were diagnosed with AA: 464 appendectomies and 27 diagnostic laparoscopies were performed. The NA rate was 4.2%. The sensitivity and specificity for TUS and CT are as follows: 71.4% and 96.2%; 93.8% and 93.6%. (4) Conclusion: A conditional CT strategy is effective in reducing NA rates and avoids unnecessary CT in a large proportion of patients. Observation and repeated TUS might be useful in unclear cases.

Morphologic criteria of vermiform appendix on computed tomography and a possible risk of developing acute appendicitis. Radiol Bras 2019; 52:217-221.

Abstract
Objective To evaluate the correlation of morphological criteria of the cecal appendix
using computed tomography (CT) and the possible risk of developing acute
appendicitis. Materials and Methods Cases were defined as patients with surgically confirmed acute appendicitis
who had undergone CT at least twice: at diagnosis and at least one month
prior. Controls were defined as emergency patients with abdominal pain who
had undergone abdominal CT that excluded acute appendicitis and had also
undergone CT at least one month before. Results 100 cases and 100 controls were selected for inclusion in the final analysis.
Comparisons between the cases and controls revealed the following: mean
transverse diameter of 0.6 cm (range, 0.4-1.0 cm) versus 0.6 cm (range,
0.6-0.8 cm; p = 0.37); mean length of 6.6 cm (range,
3.5-9.7 cm) versus 6.6 cm (range, 4.5-8.3 cm; p = 0.87);
mean angle of 100° (range, 23-178°) versus 86° (range, 43-160°;
p = 0.01); vertical descending orientation in 56%
versus 45% (p = 0.2); absence of gas in 69% versus 77%
(p = 0.34); and presence of an appendicolith in 17%
versus 8% (p = 0.08). Conclusion Hypothetical risk factors for obstruction of the vermiform appendix detected
on CT were not associated with acute appendicitis. That suggests that
factors other than those related to mechanical obstruction are implicated in
the pathogenesis of acute appendicitis.

Abstract
Acute appendicitis is one of the most common abdominal emergencies. An accurate preoperative diagnosis is still a challenge in many cases. Patient history and clinical examination are the mainstay of diagnostics but other tools are also needed in order to reduce the number of misdiagnoses. Laboratory parameters and radiological imaging procedures are widely used and scoring systems can help in the risk stratification of patients with suspected appendicitis. In the USA most patients undergo preoperative computed tomography (CT) as the first-line examination, which can reduce the number of negative appendectomies to less than 5%; however, this practice results in substantial radiation exposure and is less accepted in Europe due to concerns about radiation-induced cancer in the often younger patients. Ultrasound is a valuable first-line imaging procedure and in experienced hands can achieve very good results. In patients with an equivocal diagnosis inpatient surveillance with close control of clinical and laboratory parameter represents a suitable method to reduce the number of negative explorations without resulting in an increase in the rate of perforation or morbidity.

Standardized reporting of appendicitis-related findings improves reliability of ultrasound in diagnosing appendicitis in children. J Pediatr Surg 2018; 53:984-987.

Abstract
PURPOSE Our objective was to increase ultrasound reliability for diagnosing appendicitis in an academic children's hospital emergency department (ED) through a multidisciplinary quality improvement initiative. METHODS A retrospective review of ultrasound use in patients diagnosed with appendicitis in our ED from 1/1/2011 to 6/30/2014 established a baseline cohort. From 8/1/2014 to 7/31/2015 a diagnostic algorithm that prioritized ultrasound over CT was used in our ED, and a standardized template was implemented for the reporting of appendicitis-related ultrasound findings by our radiologists. RESULTS Of 627 patients diagnosed with appendicitis in the ED during the retrospective review, 46.1% (n=289) had an ultrasound. After implementation of the diagnostic algorithm and standardized ultrasound report, 88.4% (n=236) of 267 patients diagnosed with appendicitis had an ultrasound (p<0.01). The frequency of indeterminate results decreased from 44.3% to 13.1%, and positive results increased from 46.4% to 66.1% in patients with appendicitis (p<0.01). The sensitivity of ultrasound (indeterminate counted as negative) increased from 50.6% to 69.2% (p<0.01). CONCLUSIONS Ultrasound reliability for the diagnosis of appendicitis in children can be improved through standardized results reporting. However, these changes should be made as part of a multidisciplinary quality improvement initiative to account for the initial learning curve necessary to increase experience.
