- Diabetic Foot Assessment and Care: Barriers and Facilitators in a Cross-Sectional Study in Bangalore, India(2023) SUDHA, B. G.; UMADEVI, V.; SHIVARAM, J. M.; BELEHALLI, P.; SHEKAR, M. A.; CHALUVANARAYANA, H. C.; SIKKANDAR, M. Y.; BRIOSCHI, M. L.(1) Background: This cross-sectional study aims to highlight the assessment and foot care practices in an advanced clinical setting, the clinical characteristics of the patients, and to understand the barriers and facilitators for effective foot care from the perspectives of healthcare practices, resources, and patients’ socioeconomic and cultural practices, and other aspects in terms of new technologies for effective foot care such as infrared thermography. (2) Methods: Clinical test data from 158 diabetic patients and a questionnaire to assess the foot care education retention rate were collected at the Karnataka Institute of Endocrinology and Research (KIER) facility. (3) Results: Diabetic foot ulcers (DFUs) were found in 6% of the examined individuals. Male patients were more likely to have diabetes complications, with an odds ratio (OR) of 1.18 (CI = 0.49–2.84). Other diabetes problems raised the likelihood of DFUs by OR 5 (CI = 1.40–17.77). The constraints include socioeconomic position, employment conditions, religious customs, time and cost, and medication non-adherence. The attitude of podiatrists and nurses, diabetic foot education, and awareness protocols and amenities at the facility were all facilitators. (4) Conclusions: Most diabetic foot complications might be avoided with foot care education, regular foot assessments as the standard of treatment, and self-care as a preventive/therapeutic strategy.
- Infrared Imaging of the Brain-Eyelid Thermal Tunnel: A Promising Method for Measuring Body Temperature in Afebrile Children(2023) MENECK, F. De; SANTANA, V.; BRIOSCHI, G. C.; HADDAD, D. S.; NEVES, E. B.; FRANCO, M. D. C.; BRIOSCHI, M. L.(1) Infrared thermography of the inner canthus of the eye has emerged as a promising tool for temperature screening and fever diagnosis. Its non-invasive nature lends itself well to mass screening in diverse settings such as schools, public transport, and healthcare facilities. Swift and accurate temperature assessment plays a pivotal role in the early identification of potential fever cases, facilitating timely isolation, testing, and treatment, thereby mitigating the risk of disease transmission. Nonetheless, the reliability of this approach in the pediatric population, especially when compared to conventional thermometry methods, remains unexplored. This preliminary study aimed to evaluate the concordance between the temperature of the inner canthus of the eye (Tic,eye), referred to as the brain-eyelid thermal tunnel (BTT°), with axillary and tympanic methods in afebrile children. (2) Methods: A cohort of 36 children, matched in a 1:1 ratio for gender and age, underwent comprehensive assessments encompassing anthropometric data, blood pressure evaluations, axillary (Tax) and tympanic (Tty) temperature measurements, as well as BTT° infrared thermography. (3) Results: The findings revealed a high level of concordance among the tympanic, axillary, and BTT° measurement methods. Bland–Altman plots showed that the bias was minimal, and no statistically significant differences were observed when comparing BTT° with axillary (p = 0.136) and tympanic (p = 0.268) measurements. Passing–Bablok regression scatter plots further confirmed the agreement, aligning the fitted regression line closely with the identity line for both axillary versus BTT° and tympanic (Tty) versus BTT° comparisons. (4) Conclusions: This study holds significant implications for public health, especially in the context of infectious disease outbreaks such as COVID-19. BTT° infrared thermography of the inner canthus of the eye (Tic,eye) reliably measures body temperature in afebrile children in controlled settings; nevertheless, its practical application necessitates the adaptation of biothermodynamic parameters to accommodate diverse environmental conditions.
- Thermographic and clinical correlation of myofascial trigger points in the masticatory muscles(2012) HADDAD, D. S.; BRIOSCHI, M. L.; ARITA, E. S.Objectives: The aim of the study was to identify and correlate myofascial trigger points (MTPs) in the masticatory muscles, using thermography and algometry. Methods: 26 female volunteers were recruited. The surface facial area over the masseter and anterior temporalis muscles was divided into 15 subareas on each side (n = 780). This investigation consisted of three steps. The first step involved thermographic facial examination, using lateral views. The second step involved the pressure pain threshold (PPT), marking the MTP pattern areas for referred pain (n = 131) and local pain (n = 282) with a coloured pencil, and a photograph of the lateral face with the head in the same position as the infrared imaging. The last step was the fusion of these two images, using dedicated software (Reporter (R) 8.5-SP3 Professional Edition and QuickReport (R) 1.2, FLIR Systems, Wilsonville, OR); and the calculation of the temperature of each point. Results: PPT levels measured at the points of referred pain in MTPs (1.28 +/- 0.45 kgf) were significantly lower than the points of local pain in MTPs (1.73 +/- 0.59 kgf; p < 0.05). Infrared imaging indicated differences between referred and local pain in MTPs of 0.5 degrees C (p < 0.05). Analysis of the correlation between the PPT and infrared imaging was done using the Spearman non-parametric method, in which the correlations were positive and moderate (0.4 <= r < 0.7). The sensitivity and specificity in MTPs were 62.5% and 71.3%, respectively, for referred pain, and 43.6% and 60.6%, respectively, for local pain. Conclusion: Infrared imaging measurements can provide a useful, non-invasive and non-ionizing examination for diagnosis of MTPs in masticatory muscles.

bookPart Termografia e acupuntura em dor neuropática(2023) DALMASO NETO, Carlos; YENG, Lin Tchia; TEIXEIRA, Manoel Jacobsen; BRIOSCHI, Marcos Leal- Can Dual Infrared-Visual Thermography Provide a More Reliable Diagnosis of Perforator Veins and Reflux Severity?(2023) DAVALOS, Marcelo Pastor Almada; BRIOSCHI, Marcos Leal; ROSA, Samir Ezequiel da; BRIOSCHI, Gabriel Carneiro; NEVES, Eduardo BorbaThe accurate identification of perforator veins (PV) in asymptomatic veins that do not meet the criteria established by venous Doppler (VD) is a complex challenge, considered the gold standard in diagnosis, and is operator-dependent. This study explored the potential of dual infrared-visual thermography (IRVT) to identify PV in 99 patients aged 29 to 80 years. IRVT was conducted using a high-definition hyperspectral visual-infrared sensor. The temperature difference (Delta T) between maximum temperature (Tmax) and minimum temperature (Tmin) within the region of interest (ROI) served as an indicator for assessing vascular dysfunction severity. Comparative analysis was performed with VD results obtained using a Doppler ultrasound unit equipped with a 7.5 MHz linear transducer. Significant statistical differences (p < 0.05) in Delta T (Tmax-Tmin) were observed among PV sites categorized by reflux severity: no reflux (Delta T = 1.2 degrees C), mild reflux (Delta T = 1.8 degrees C), moderate reflux (Delta T = 2.9 degrees C), and severe reflux (Delta T = 3.6 degrees C). This study concludes that IRVT effectively distinguishes varying degrees of vascular reflux severity. IRVT shows promise as a non-invasive, radiation-free tool to enhance PV identification, especially in challenging cases, potentially improving patient outcomes and healthcare management. Further research is required to validate and refine its diagnostic utility.
- Exploring Facial Thermography Patterns in Women with Chronic Migraine(2023) FRACASSO, Bruno Veloso; CASTRO, Renato Bender; BRIOSCHI, Marcos Leal; MALYSZ, Tais(1) Background: Chronic migraine is a debilitating neurological condition affecting millions worldwide. This study delves into the facial point-of-care (POC) thermographic patterns of women with chronic migraine, aiming to shed light on the condition's pathophysiology and diagnostic potential. (2) Methods: Using infrared POC thermography, the facial temperature distribution of 24 female participants with chronic migraine were analyzed. (3) Results: The findings revealed significant temperature asymmetry in women with right-sided unilateral headaches, particularly in the right frontal and temporal regions. Notably, individuals with bilateral pain did not exhibit thermal pattern differences, suggesting potential diagnostic complexities. While these results offer valuable insights, further research with larger samples is warranted (4) Conclusions: Facial thermography holds promise as an adjunctive tool for migraine diagnosis and understanding its neurophysiological basis; however, cautious interpretation is advised, given the need for validation and expanded investigations. Improved diagnostic criteria and treatment strategies may emerge from this ongoing exploration, ultimately enhancing the quality of life of chronic migraine sufferers.
