OBJECTIVES@#To observe the changes of skin blood flow perfusion at Waiguan (TE 5) caused by mild moxibustion with moxa stick and infrared mild moxibustion using laser speckle contrast imaging technology, and to compare the microcirculatory effect during and after both moxibustion methods and explore the dose-response relationship of moxibustion.@*METHODS@#Twenty-four healthy participants were treated with mild moxibustion with moxa stick and infrared mild moxibustion at left Waiguan (TE 5). The record started when the skin temperature reached (44±1) °C, and both moxibustion methods were provided within this temperature range. The 20-minute moxibustion process was divided into four stages (5, 10, 15, and 20 min) using interpolation method, and each participant completed eight interventions with a minimum 24-hour interval between different interventions. The skin surface temperature of the left Waiguan (TE 5) was monitored when both moxibustion interventions were given for 10 min using a TES1306 thermocouple thermometer. The skin microcirculatory blood perfusion units (MBPU) of left Waiguan (TE 5) was measured using a PSIN-01087 laser speckle blood flow imager 1 min before moxibustion, at 5, 10, 15, 20 min during moxibustion and continuously for 20 min after moxibustion in each intervention.@*RESULTS@#The skin surface temperature of the left Waiguan (TE 5) remained within the range of (44±1) °C during both moxibustion methods, with no statistically significant difference (P>0.05). Compared with that before moxibustion, the MBPU of the left Waiguan (TE 5) was increased significantly at 5, 10, 15, and 20 min of both moxibustion methods (P<0.05, P<0.01). Compared with moxibustion for 10, 15 and 20 min, the MBPU of the left Waiguan (TE 5) of moxibustion for 5 min was lower in both moxibustion methods (P<0.01). For both moxibustion methods with the same moxibustion course, the MBPU of the left Waiguan (TE 5) 20 min after intervention was significantly higher than that at 1 min before moxibustion (P<0.001), and there was no significant difference in MBPU between 1 min before moxibustion and 20 min after moxibustion among different groups (P>0.05). Within the same moxibustion method, the MBPU of the left Waiguan (TE 5) 20 min after moxibustion with the intervention of 5 min was lower compared to that of 10, 15, and 20 min of moxibustion (P<0.001), with no significant differences between 10, 15, and 20 min of moxibustion (P>0.05).@*CONCLUSIONS@#When controlling the skin temperature at Waiguan (TE 5) within (44±1) °C, infrared mild moxibustion has similar effects on skin microcirculatory blood perfusion as traditional mild moxibustion with moxa sticks. From a dose-response perspective, microcirculation reached a stable state after 10 min of moxibustion, and moxibustion interventions lasting for more than 10 min shows better therapeutic effects.

OBJECTIVE@#To investigate the changes of skin temperature, blood infusion and inflammatory cytokines of cutaneous tissue in the sensitized area of colitis model rats, as well as the relationship between sensory and sympathetic nerves and the formation of sensitized area, and to initially reveal the partial physical-chemical characteristics of the sensitized area in the colitis model rats.@*METHODS@#Thirty-five male SD rats were randomly divided into a control group (n=10), a model group (n=18) and a guanethidine group (n=7). 5% dextran sulfate sodium (DSS) was adopted for 6-day free drinking to establish colitis model in the model group and the guanethidine group. On day 6 and 7, in the guanethidine group, guanethidine solution (30 mg/kg) was injected intraperitoneally for sympathetic block. On day 7, after injection of evans blue (EB) solution, the EB extravasation areas on the body surface were observed to investigate the distribution and physical-chemical characteristics of the sensitized area. The control area was set up, 0.5 cm away from the sensitized area, and with the same nerve segment innervation. Disease activity index (DAI) score of rats was compared between the normal group and the model group, and the morphological changes in the colon tissue were investigated with HE method. Using infrared thermal imaging technology and laser speckle flow imaging technology, skin temperature and blood infusion were determined in the sensitized area and the control area of the rats in the model group. Immunofluorescence technique was adopted to observe the expression levels of the positive nerve fibers of substance P (SP), calcitonin gene-related peptide (CGRP) and tyrosine hydroxylase (TH), and the correlation with blood vessels; as well as the expression levels of SP positive nerve fibers/tryptase+ mast cells, and tryptase+ mast cells/5-hydroxytryptamine (5-HT) in skin tissue in the sensitized area and the control area of the rats in the model group. MSD multi-level factorial method and ELISA were applied to determine the contents of pro-inflammatory and anti-inflammatory cytokines (e.g. TNF-α, IL-1β, IL-6, IL-4 and IL-10) and anti-inflammatory substance corticosterone (CORT).@*RESULTS@#Sensitization occurred at the T12-S1 segments of the colitis model rats, especially at L2-L5 segments. Compared with the normal group, DAI score was increased in the rats of the model group (P<0.05), and the colonic mucosal damage was obvious, with the epithelial cells disordered, even disappeared, crypt destructed, submucosal edema and a large number of inflammatory cells infiltrated. In comparison with the control area, the skin temperature and blood infusion were increased in the sensitized area of the model group (P<0.05, P<0.01); as well as the expression levels of the positive nerve fibers of SP, CGRP and TH of skin tissue (P<0.05), which was specially distributed in peripheral vessels, the expression levels of SP positive nerve fibers/tryptase+ mast cells, and tryptase+ mast cells/5-HT of the skin tissue were all expanded (P<0.05) in the sensitized area of the model group. Compared with the model group, the number of sensitized areas was reduced in the guanethidine group (P<0.05). In comparison with the control area of the model group, in the sensitized area, the contents of pro-inflammatory cytokines, e.g. TNF-α, IL-1β and IL-6, and the anti-inflammatory substance CORT of skin tissue were all increased (P<0.05); and the contents of IL-6 and TNF-α were negatively correlated with CORT (P<0.05).@*CONCLUSION@#The sensitized areas on the body surface of colitis rats are mainly distributed in the L2-L5 segments. Sensory and sympathetic nerves are involved in the acupoint sensitization, and the sensitized areas may have the dynamic changes in pro-inflammatory and anti-inflammatory substances.

O objetivo foi realizar uma análise crítica sobre os principais aspectos metodológicos empregados nas pesquisas sobre a resposta da temperatura da pele por termografia infravermelha, bem com seu comportamento durante diferentes formas de exercício, além de descrever as alterações que ocorrem no decorrer do processo de recuperação de até uma hora. Foi realizada uma busca sistemática nas bases de dados MEDLINE/Pubmed, Scielo e Science Direct, utilizando os termos "thermography" and "exercise", no período de janeiro de 2012 a outubro de 2021, sendo incluídos apenas estudos realizados em laboratório. Os principais resultados indicam que a maior parte dos estudos são realizados com homens, adultos, com número amostral restrito. A região de membros inferiores é a mais estudada. O treinamento de força compreendeu 54% dos estudos. Durante exercício progressivo, existe uma clara tendência de redução da temperatura, enquanto no exercício de carga contínua isso somente ocorre nos momentos iniciais. Como conclusão, têm-se uma carência de estudos com mulheres e grupos com faixas etárias extremas, e os procedimentos de análise de imagens não são uniformes entre os estudos. A resposta da temperatura da pele é diferente em função do tipo de exercício realizado (progressivo ou constante), bem como da região exercitada. (AU)
The objective was critically to analyze the main methodological aspects employed in research studies investigating the response of skin temperature to exercise measured via thermography, as well as to describe the behaviour of during and until 1 h after different modes of exercise. A systematic search was performed in the MEDLINE/Pubmed, Scielo, and Science Direct databases using the keywords thermography AND exercise, between January 2012 to October 2021. Only laboratory studies were included. The main results indicate that most studies were performed with male adults, with small sample size. Lower limbs represent the body region more studied. Regarding exercise mode, strength training abranged 54% of studies. During progressive exercise there is clearly a skin temperature reduction, and during continuous exercise of constant load the decrease occur at initial moments of exercise. In conclusion, there is a lack of studies analyzing female and broader age groups, and procedures for analyzing images are not uniform across studies. The skin temperature response to exercise is different according with the mode of exercise performed (constant or progressive load) and exercised body region. (AU)

BACKGROUND: Ice cooling vests can cause tissue damage and have no flexibility. Therefore, these two undesirable properties of ice cooling vest were optimized, and the present study was aimed to compare the impact of the optimized ice cooling vest and a commercial paraffin cooling vest on physiological and perceptual strain under controlled conditions. METHODS: For optimizing, hydrogel was used to increase the flexibility and a layer of the ethylene vinyl acetate foam was placed into the inside layer of packs to prevent tissue damage. Then, 15 men with an optimized ice cooling vest, with a commercial paraffin cooling vest, and without a cooling vest performed tests including exercise on a treadmill (speed of 2.8 km/hr and slope of %0) under hot (40℃) and dry (40 %) condition for 60 min. The physiological strain index and skin temperature were measured every 5 and 15 minutes, respectively. The heat strain score index and perceptual strain index were also assessed every 15 minutes. RESULTS: The mean values of the physiological and perceptual indices differed significantly between exercise with and without cooling vests (P 0.05). CONCLUSIONS: The optimized ice cooling vest was as effective as the commercial paraffin cooling vest to control the thermal strain. However, ice has a greater latent heat and less production cost.

BACKGROUND: The authors have performed ultrasound-guided stellate ganglion block (SGB) in our clinic using a lateral paracarotid approach at the level of the 6th cervical vertebra (C6). Although SGB at C6 is a convenient and safe method, there are ongoing concerns about the weak effect of sympathetic blockade in the ipsilateral upper extremity. Therefore, ultrasound-guided SGB was attempted using a lateral paracarotid approach at the level of the 7th cervical vertebra (C7). This prospective study aimed to compare changes in skin temperature after SGB was performed at C6 and C7, and to introduce a lateral paracarotid approach for SGB.METHODS: Thirty patients underwent SGB twice: once at C6 and once at C7. For every SGB, the skin temperature of the patient's hypothenar area was measured for 15 min at 1-min intervals. Skin temperatures before and after SGB and side effects were compared between C6 and C7 groups.RESULTS: The temperature of the upper extremity increased after SGB was performed at C6 and C7. There were significant differences between mean pre-SGB and the largest increases in post-SGB temperatures (0.50±0.38℃ and 1.41±0.68℃ at C6 and C7, respectively; p < 0.05). Significantly increased post-SGB temperatures (difference >1℃) were found in 5/30 (16.7%) and 24/30 (80%) cases for C6 and C7, respectively (p < 0.05). There were no significant differences in side effects between SGB performed at C6 or C7 (p>0.05).CONCLUSION: The lateral paracarotid approach using out-of-plane needle insertion for ultrasound-guided SGB performed at C7 was feasible and more effective at elevating skin temperature in the upper extremity than SGB at C6.

BACKGROUND: A stellate ganglion block (SGB) causes increased blood flow in the maxillofacial region, exhibiting the potential for regenerative effects in damaged tissue. The focus of this study was to understand the efficacy of SGB for regenerative effects against nerve damage. A rat model of the superior cervical ganglion block (SCGB) was created instead of SGB, and facial blood flow, as well as sympathetic nervous system function, were measured. METHODS: A vertical incision was made on the left side of the neck of a Wistar rat, and a 5-mm resection of the superior cervical ganglion was performed at the back of the bifurcation of the internal and external branches of the left common carotid artery. Blood flow in the skin at the mandibular angle and mean facial temperature were measured using a laser-Doppler blood flow meter and a thermographic camera, respectively, over a 5-week period after the block. In addition, the degree of ptosis and miosis were assessed over a period of 6 months. RESULTS: The SCGB rat showed significantly higher blood flow at the mandibular angle on the block side (P < 0.05) for 3 weeks, and significantly higher skin temperature (P < 0.05) for 1 week after the block. In the SCGB rat, ptosis and miosis occurred immediately after the block, and persisted even 6 months later. CONCLUSIONS: SCGB in rats can cause an increase in the blood flow that persists over 3 weeks.

Abstract Objective This study verified the occurrence of dental sensitivity in patients submitted to a 35% hydrogen peroxide based product (Whiteness HP Maxx 35% - FGM), skin cold sensation threshold (SCST) and its influence on dental sensitivity. Material and Methods Sixty volunteers were divided into 4 groups (n = 15), according to SCST (low: GI and GIII, and high: GII and IV) and bleaching treatment (hydrogen peroxide: GI and GII, and placebo: GIII and GIV). SCST was determined in the inner forearm for 6 different times using a neurosensory analyzer, the TSA II (Medoc Advanced Medical Systems, Ramat Yishai, Northern District, Israel). Dental sensitivity measurements were performed 10 different times using a thermal stimulus and an intraoral device attached to TSA II, positioned in the buccal surface of the upper right central incisor. Spontaneous dental sensitivity was also determined using the Visual Analogue Scale (VAS). Data were submitted to Student's t-test and Pearson's Correlation Test (α=0.05). SCST remained the same during bleaching treatment. Results Distinct responses of dental sensitivity were found in patients with low and high SCST during the first and third bleaching session (p≤0.05). The teeth submitted to the bleaching treatment became more sensitive to cold than those treated with placebo. Moreover, data obtained with TSA and VAS presented moderate correlation. Conclusions Bleaching treatment increased dental sensitivity and skin cold sensation threshold might represent a determining factor in this occurrence, since low and high SCST patients had different responses to the thermal stimulus in the teeth.

<p><b>OBJECTIVE</b>This study aims to investigate the relationship between major signal points (MaSPs) of the lower extremities used in court-type Thai traditional massage (CTTM) and the corresponding underlying anatomical structures, as well as to determine the short-term changes in blood flow and skin temperature of volunteers experiencing CTTM.</p><p><b>METHODS</b>MaSPs were identified and marked on cadavers before acrylic color was injected. The underlying structures marked with acrylic colors were observed and the anatomical structures were determined. Then, pressure was applied to each MaSP in human volunteers (lateral side of leg and medial side of leg) and blood flow on right dorsalis pedis artery was measured using duplex ultrasound while skin temperature changes were monitored using an infrared themographic camera.</p><p><b>RESULTS</b>Short-term changes in the blood flow parameters, volume flow and average velocity, compared to baseline (P < 0.05), were observed on MaSP of the lower extremity, ML4. Changes in the peak systolic velocity of the area ML5 were also observed relative to baseline. The skin temperature of two different MaSPs on the lateral side of leg (LL4 and LL5) and four on the medial side of leg (ML2, ML3, ML4 and ML5) was significantly increased (P < 0.05) at 1 min after pressure application.</p><p><b>CONCLUSION</b>This study established the clear correlation between the location of MaSP, as defined in CTTM, and the underlying anatomical structures. The effect of massage can stimulate skin blood flow because results showed increased skin temperature and blood flow characteristics. While these results were statistically significant, they may not be clinically relevant, as the present study focused on the immediate physiological effect of manipulation, rather than treatment effects. Thus, this study will serve as baseline data for further clinical studies in CTTM.</p>

Abstract: Background: Low temperatures and slow blood flow may result from peripheral neuropathy caused by leprosy, and the simple detection of cold fingers could already be a preliminary classification for these patients. Objective: To investigate whether infrared thermography would be able to measure this change in temperature in the hands of people with leprosy. Method: The study assessed 17 leprosy patients who were under treatment at the National Reference Center for Sanitary Dermatology and Leprosy, Uberlândia/MG, and 15 people without leprosy for the control group. The infrared camera FLIR A325 and Therma CAM Researcher Professional 2.9 software were used to measure the temperature. The room was air-conditioned, maintaining the temperature at 25°C; the distance between the camera and the limb was 70 cm. The vasomotor reflex of patients was tested by a cold stress on the palm. Results: The study showed a significant interaction between the clinical form of leprosy and temperature, where the control group and the borderline-borderline form revealed a higher initial temperature, while borderline-lepromatous and lepromatous leprosy showed a lower temperature. Regarding vasomotor reflex, lepromatous leprosy patients were unable to recover the initial temperature after cold stress, while those with the borderline-tuberculoid form not only recovered but exceeded the initial temperature. Conclusion: Thermography proved a potential tool to assist in the early detection of neuropathies, helping in the prevention of major nerve damage and the installation of deformities and disabilities that are characteristic of leprosy.

BACKGROUND: The location and the number of lumbar sympathetic ganglia (LSG) vary between individuals. The aim of this study was to determine the appropriate level for a lumbar sympathetic ganglion block (LSGB), corresponding to the level at which the LSG principally aggregate. METHODS: Seventy-four consecutive subjects, including 31 women and 31 men, underwent LSGB either on the left (n = 31) or the right side (n = 43). The primary site of needle entry was randomly selected at the L3 or L4 vertebra. A total of less than 1 ml of radio opaque dye with 4% lidocaine was injected, taking caution not to traverse beyond the level of one vertebral body. The procedure was considered responsive when the skin temperature increased by more than 1℃ within 5 minutes. RESULTS: The median responsive level was significantly different between the left (lower third of the L4 body) and right (lower margin of the L3 body) sides (P = 0.021). However, there was no significant difference in the values between men and women. The overall median responsive level was the upper third of the L4 body. The mean responsive level did not correlate with height or BMI. There were no complications on short-term follow-up. CONCLUSIONS: Selection of the primary target in the left lower third of the L4 vertebral body and the right lower margin of the L3 vertebral body may reduce the number of needle insertions and the volume of agents used in conventional or neurolytic LSGB and radiofrequency thermocoagulation.

By studying the relationship between fingertip temperature changes and arterial function during vascular reactivity test, we established a new non-invasive method for detecting vascular function, in order to provide an assistance for early diagnosis and prevention of cardiovascular diseases. We customized three modules respectively for blood occlusion, measurement of finger temperature and blood oxygen acquisition, and then we established the hardware of data acquisition system. And the software was programmed with Labview. Healthy subjects [group A, n = 24, (44.6 ± 9.0) years] and subjects with cardiovascular diseases [group B, n = 33, (57.2 ± 9.9) years)] were chosen for the study. Subject's finger temperature, blood oxygen and occlusion pressure of block side during and after unilateral arm brachial artery occlusion were recorded, as well as some other regular physiological indexes. By time-domain analysis, we extracted 12 parameters from fingertip temperature signal, including the initial temperature (Ti), temperature rebound (TR), the time of the temperature recovering to initial status (RIt) and other parameters from the finger temperature signal. We in the experiment also measured other regular physiological body mass index (BMI), systolic blood pressure (SBP), diastiolic blood pressure (DBP) and so on. Results showed that 8 parameters difference between the two group of data were significant. based on the statistical results. A discriminant function of vascular function status was established afterwards. We found in the study that the changes of finger temperature during unilateral arms brachial artery occlusion and open were closely related to vascular function. We hope that the method presented in this article could lay a foundation of early detection of vascular function.

PURPOSE: The purpose of this cross-over experimental study was to examine effects of music intervention on maternal anxiety, fetal heart rate pattern and testing time during non-stress tests (NST) for antenatal fetal assessment. METHODS: Sixty pregnant women within 28 to 40 gestational weeks were randomly assigned to either the experimental group (n=30) or control group (n=30). Music intervention was provided to pregnant women in the experimental group during NST. Degree of maternal anxiety and fetal heart rate pattern were our primary outcomes. State-trait anxiety inventory, blood pressure, pulse rate, and changes in peripheral skin temperature were assessed to determine the degree of maternal anxiety. Baseline fetal heart rate, frequency of acceleration in fetal heart rate, fetal movement test and testing time for reactive NST were assessed to measure the fetal heart rate pattern. RESULTS: The experimental group showed significantly lower scores in state anxiety than the control group. There were no significant differences in systolic blood pressure and pulse rate between the two groups. Baseline fetal heart rate was significantly lower in the experimental group than in the control group. Frequency of acceleration in fetal heart rate was significantly increased in the experimental group compared to the control group. There were no significant differences in fetal movement and testing time for reactive NST between the two groups. CONCLUSION: Present results suggest that music intervention could be an effective nursing intervention for alel viating anxiety during non-stress test.

The quantitative sudomotor axon reflex testing (QSART) is a classic test of routine postganglionic sudomotor function. We investigated sudomotor function by QSART after summer (July 2012) and winter (January 2013) seasonal acclimation (SA) in the Republic of Korea. QSART with acetylcholine (ACh) iontophoresis were performed to determine directly activated (DIR) and axon reflex-mediated (AXR1, 2) sweating rate. Onset time of axon reflex, activated sweat gland density (ASGD), activated sweat gland output (ASGO), tympanic and skin temperatures (T(ty), T(sk)), basal metabolic rate (BMR), and evaporative loss volume changes were measured. Tympanic and mean body temperature (T(b); calculated from T(ty), T(sk)) were significantly lower after summer-SA than that of winter-SA. Sweat onset time was delayed during winter-SA compared to that after summer-SA. BMR, AXR(1), AXR(2), and DIR sweat rates, ASGD and ASGO, and evaporative loss volume were significantly diminished after winter-SA relative to after summer-SA. In conclusion, changes in sweating activity measured by QSART confirmed the involvement of the peripheral nervous system in variation of sudomotor activity in seasonal acclimation.

Objective To evaluate if body surface temperature close to the central venous catheter insertion area is different when patients develop catheter-related bloodstream infections.Methods Observational cross-sectional study. Using a non-contact infrared thermometer, 3 consecutive measurements of body surface temperature were collected from 39 patients with central venous catheter on the following sites: nearby the catheter insertion area or totally implantable catheter reservoir, the equivalent contralateral region (without catheter), and forehead of the same subject.Results A total of 323 observations were collected. Respectively, both in male and female patients, disregarding the occurrence of infection, the mean temperature on the catheter area minus that on the contralateral region (mean ± standard deviation: -0.3±0.6°C versus-0.2±0.5ºC; p=0.36), and the mean temperature on the catheter area minus that on the forehead (mean ± standard deviation: -0.2±0.5°C versus-0.1±0.5ºC; p=0.3) resulted in negative values. Moreover, in infected patients, higher values were obtained on the catheter area (95%CI: 36.6-37.5ºC versus 36.3-36.5ºC; p<0.01) and by temperature subtractions: catheter area minus contralateral region (95%CI: -0.17 - +0.33ºC versus -0.33 - -0.20ºC; p=0.02) and catheter area minus forehead (95%CI: -0.02 - +0.55ºC versus-0.22 - -0.10ºC; p<0.01).Conclusion Using a non-contact infrared thermometer, patients with catheter-related bloodstream infections had higher temperature values both around catheter insertion area and in the subtraction of the temperatures on the contralateral and forehead regions from those on the catheter area.
Objetivo Avaliar se a temperatura da superfície corporal nas proximidades da área de inserção do cateter venoso central é diferente quando os pacientes desenvolvem infecções da corrente sanguínea relacionadas ao cateter.Métodos Estudo transversal observacional. Usando um termômetro infravermelho sem contato, 3 medições consecutivas de temperatura da superfície corporal foram coletadas de 39 pacientes com cateter venoso central nos seguintes locais: nas proximidades da área de inserção do cateter ou do reservatório do cateter totalmente implantável, na região contralateral equivalente (sem cateter), e na fronte do mesmo paciente.Resultados Um total de 323 observações foram coletadas. Respectivamente nos pacientes do sexo masculino e feminino, desconsiderando a ocorrência de infecção, a temperatura média na área do cateter menos a da região contralateral (média ± desvio padrão: -0,3±0,6°C versus -0,2±0,5°C; p=0,36) e a da área do cateter menos a da fronte (média ± desvio padrão: -0,2±0,5°Cversus -0,1±0,5°C; p=0,3) resultaram em valores negativos. Além disso, em pacientes infectados, foram obtidos valores mais elevados na área do cateter (IC95%: 36,6-37,5ºC versus36,3-36,5ºC; p<0,01) e nas subtrações de temperaturas: área do cateter menos região contralateral (IC95%: -0,17 - +0,33°C versus-0,33 - -0,20°C; p=0,02) e a área do cateter menos fronte (IC95%:-0,02 - +0,55°C versus -0,22 - -0,10ºC; p<0,01).Conclusão Utilizando um termômetro infravermelho sem contato, os pacientes com infecções da corrente sanguínea associadas ao cateter apresentaram valores de temperatura mais elevados, tanto ao redor da área de inserção do cateter e na subtração das temperaturas das regiões contralateral e fronte, em relação àquelas da área do cateter.

PURPOSE: In the pathophysiology of sepsis tissue perfusion dysfunction is a crucial driving force. Thus the early recognition is highly important. Concerning the early hours of bacteremia, and the systemic inflammatory response reaction leading to sepsis we aimed to investigate the micro- and macrocirculatory changes. METHODS: In 20 juvenile Hungahib pigs were anesthetized and the femoral artery and external jugular vein were prepared unilaterally and cannulated. For assisted ventilation tracheostomy was performed. In Sepsis group (n=11) live E. coli was intravenously administered (increasing concentration, 9.5x10∧6 in 3h). In Control group (n=9) bacteria-free saline was administered at the same volume. Modified shock index (MSI), core and skin temperature, and skin microcirculation (laser Doppler) were measured before inducing bacteremia then hourly for 4h. RESULTS: In Control group parameters were stable, while six animals in the Sepsis group died before the 4th hour. Core and skin temperature did not show significant alterations. In Sepsis group microcirculation showed a large impairment already by the 1st hour, while in MSI only by the 3rd hour. CONCLUSION: During bacteremia and the early phase of sepsis microcirculatory impairment can be detected soon, even hours before the deterioration in hemodynamic parameters in this porcine model. .

Manipulation of the spinal column is a manual therapeutic resource characterized by passive thrust of a given joint at a high velocity and low amplitude within the limits of anatomic integrity. The objective of the present study was to assess the immediate effects of upper thoracic manipulation on skin temperature in the vertebral region in healthy women. Thus, a randomized controlled blind trial was realized in the university community. Twenty-six healthy women were randomly allocated into an experimental group (n=13) and a placebo group (n=13). A single session of upper thoracic spine manipulation (segment T3) was performed. Infrared thermography was used to determine changes in skin temperature in the vertebral region. Images were taken prior to, immediately after and both five and 10 minutes after manipulation. Two-way repeated measures analysis of variance with post hoc Bonferroni test was used for inter and intragroup comparisons. The level of significance was set to 5%. No significant differences were found between the different evaluation times in either group (p>0.05). In the intergroup analysis, no statistically significant differences were found in any of the comparisons (p>0.05). Based on the method employed, thoracic spine manipulation of the T3 vertebral segment does not promote changes in skin surface temperature in the region manipulated in asymptomatic individuals.
A manipulação da coluna vertebral é um recurso da terapia manual caracterizado por um impulso passivo de alta velocidade e baixa amplitude dentro dos limites de integridade anatômica de uma articulação (thrust). O objetivo do presente estudo foi avaliar os efeitos imediatos da manipulação torácica alta sobre a temperatura superficial cutânea da região vertebral em mulheres saudáveis. Para tal, foi realizado um estudo clínico randomizado cego na comunidade universitária. Vinte e seis voluntárias saudáveis foram alocadas de forma randomizada em um grupo experimental (n=13) e um grupo placebo (n=13). Uma sessão de manipulação torácica alta (segmento T3) foi realizada. Foi empregada a termografia infravermelha para determinar alterações na temperatura cutânea na região vertebral. Imagens foram capturadas antes, imediatamente após, cinco e dez minutos após a manipulação. Foi usada análise de variância com medidas repetidas (dois critérios) seguida do teste de Bonferroni para as comparações inter e intragrupos. Adotou-se um nível de significância de 5%. Não foi encontrada diferença significativa nas diferentes avaliações ao longo do tempo (p>0,05). Na análise intergrupos, não foi constatada diferença significativa nas comparações realizadas (p>0,05). Com base na metodologia empregada, a manipulação torácica do segmento vertebral T3 não promoveu alterações na temperatura superficial cutânea na região manipulada.
