“…These findings are in agreement with other studies reporting on breast reconstruction complications, with the DIEP flap to be associated with higher early flap-related complication rates, compared with other autologous or implant-based reconstructive methods. 30,31 Use of new modalities, such as preoperative infrared thermography 32 or intraoperative fluorescent angiography with indocyanine green 33,34 has recently been suggested as a useful tool for reducing perfusion-related problems, that is, flap ischemia and fat necrosis.…”

Background The use of autologous tissues is considered the mainstay for delayed breast reconstruction. Aside the free abdominal flaps, which are most commonly used, the fat-augmented latissimus-dorsi (FALD) flap has been recently shown a reliable alternative option for pure autologous breast reconstruction. In this retrospective study, we aim to compare outcomes of autologous breast reconstructions using the extended FALD and deep inferior epigastric perforator flap (DIEP) flap, with an emphasis on patients' characteristics, demographic data, complications, and patients' satisfaction after a minimum 12-month follow-up. Methods Our series consists of 135 women who underwent a delayed postmastectomy unilateral autologous breast reconstruction from 2011 to 2017: 36 patients (Group A) had an extended FALD flap and 99 (Group B) a free DIEP flap performed by the same surgeons. Demographic data, breast volume, medical history, smoking, complications, and patients' satisfaction were recorded and analyzed. Student's t-test for independent variables, Mann–Whitney U-test, and Chi-squared test were used to compare the reported variables. Results Patients' age, body mass index (BMI), and pregnancy history were statistically different between groups (p < 0.001, p = 0.004, p < 0.001, respectively); younger age (35.1 vs. 41.2 years), lower BMI (25.6 vs. 28.4), and fewer pregnancies were recorded in Group A. Breast volume was also found significantly smaller in Group A patients (p = 0.009). Past medical history using the ASA physical status classification score, previous radiation therapy, history of smoking, and incidence of overall complications were similar in both groups. Overall satisfaction scores were found slightly higher, but not statistically significant, in the free-flap group (p = 0.442). Conclusion The use of the FALD flap may provide comparable outcome to the DIEP flap in delayed breast reconstruction in terms of complications and patients' satisfaction; it should be considered a good reconstructive option for young and thin nulliparous patients, with small to medium size opposite breast.

“…The associated arterial Doppler sound confirms the selection of the vessel as a suitable perforator for free-flap harvesting on ‘gold-standard’ multidetector row computed tomography (MDCT) [ 76 ]. In a recent systematic review [ 77 ] the authors conclude that DIRT whilst still relatively novel in the surgical sphere will attract interest in the years to come particularly as the technique is easy to use and less complex than standard radiological imaging for locating skin perforators.…”

Introduction: Caesarean section (CS) is the most prevalent surgical procedure in women. The incidence of surgical site infection (SSI) after CS remains high but recent observations of CS wounds using infrared thermography has shown promise for the technique in SSI prognosis. Although thermography is recognised as a ‘surrogate’ of skin perfusion, little is known of the relationship between skin temperature and skin perfusion in the context of wound healing. Aim: To assess the extent of literature regarding the application of infrared thermography and mapping of abdominal cutaneous perfusion after CS. Methods: Wide eligibility criteria were used to capture all relevant studies of any design, published in English, and addressing thermal imaging or skin perfusion mapping of the abdominal wall. The CINAHL and MEDLINE databases were searched, with two independent reviewers screening the title and abstracts of all identified citations, followed by full-text screening of relevant studies. Data extraction from included studies was undertaken using a pre-specified data extraction chart. Data were tabulated and synthesised in narrative format. Results: From 83 citations identified, 18 studies were considered relevant. With three additional studies identified from the reference lists, 21 studies were screened via full text. None of the studies reported thermal imaging and cutaneous perfusion patterns of the anterior abdominal wall. However, two observational studies partially met the inclusion criteria. The first explored analysis methodologies to ‘interrogate’ the abdominal thermal map. A specific thermal signature (‘cold spots’) was identified as an early ‘flag’ for SSI risk. A second study, by the same authors, focusing on obesity (a known risk factor for SSI after CS) showed that a 1 °C lower abdominal skin temperature led to a 3-fold odds of SSI. Conclusion: There is a significant gap in knowledge on how to forewarn of wound complications after CS. By utilising the known association between skin temperature and blood flow, thermographic assessment of the wound and adjacent thermal territories has potential as a non-invasive, independent, imaging option with which to identify tissue ‘at risk’. By identifying skin ‘hot’ or ‘cold’ spots, commensurate with high or low blood flow regions, there is potential to shed light on the underlying mechanisms leading to infective and non-infective wound complications.

“…Infrared thermography (IRT) is an advanced measurement technique able to quantitatively measure surface temperatures of many objects simultaneously and faster than other devices [33][34][35][36]. One of the most symptoms which commonly appear after approximately six days when someone is infected with COVID-19 according to the reports of WHO, is the fever [3].…”

<span>The main challenges of today’s global health care system are to reach to strong healthcare system, to provide effective methods to eliminate the increase in the number of dead and infected with virus of COVID-19. Therefore, during the last few months, the great importance and efficacy of a variety of engineering techniques that have greatly contributed in curbing the spread of the COVID-19, and evenly help to eliminate it according to recent scientific studies was highly prominent. Among these promising technologies in this field we mention, but not limited to, the use of ultraviolet (UV) rays to disinfection of air and surfaces. In addition, thermal imaging technology, which was employed using infrared radiation for monitoring people in crowded areas and human groups to determine who have abnormal temperatures, so that all preventive measures are taken. Robots have also been used and harnessed to perform many tasks that limit the spread of the virus and maintain the integrity of the human element. Last but not least, facial recognition techniques have also been used to limit the spread of this pandemic. Ultraviolet radiation is one of physical therapy modalities that can be used to increase the efficiency of human immune system to fight the virus. In conclusion UV radiation, infrared thermal imaging, robotics, AFR technologies are now widely used to reduce the spread of this virus and manage the outbreak.</span>
