    Thermal imaging has been applied to detect possible temperature variations in various rheumatic disorders. This study sought to determine whether rheumatoid arthritis (RA) patients without active synovitis in their hands exhibit different baseline thermographic patterns of the fingers and palms when compared to healthy individuals. Data from 31 RA patients were compared to that of 51 healthy controls. The RA patients were recruited upon confirmed absence of synovitis by clinical examination and musculoskeletal ultrasound. Participants underwent medical infrared imaging of the regions of interest (ROIs). Significant differences were found between the mean temperatures of the palm regions (29.37 °C (SD2.2); n = 306) and fingers (27.16 °C (SD3.2); n = 510) of the healthy participants when compared to the palm regions (31.4(SD1.84)°C; n = 186) and fingers (30.22 °C (SD2.4); n = 299) of their RA counterparts (p = 0.001), with the latter group exhibiting higher temperatures in all ROIs. Logistic regression models confirm that both palm and finger temperature increase significantly in RA without active inflammation. These innovative findings provide evidence that baseline thermal data in RA differs significantly from healthy individuals. Thermal imaging may have the potential to become an adjunct assessment method of disease activity in patients with RA.peer-reviewe

    Management of Postsurgical Hyperhidrosis With Direct Current and Tap Water

    Background and Purpose. Excessive sweating, known as hyperhidrosis, involves the eccrine sweat glands of the axillae, soles, palms, and/or forehead. The use of iontophoresis to reduce or eliminate excessive sweating has been described since 1952. The purpose of this case report is to describe the use of tap water galvanism (TWG) using direct current (DC) with a patient who had postsurgical hyperhidrosis. Case Description. The patient was a 36-year-old male electrician with traumatic phalangeal amputation and postsurgical development of hyperhidrosis. Tap water galvanism was administered using a DC generator, 2 to 3 times per week for 10 treatments. The patient\u27s hands were individually submerged in 2 containers of tap water with the electrodes immersed directly into the containers. Each hand was treated with 30 minutes of TWG at 12 mA. Hyperhidrosis was measured by a 5-second imprint and subsequent tracing of the left hand placed on dry paper toweling. Outcomes. The patient\u27s hyperhidrosis decreased from the full left palmar pad, with a surface area of 10.3×12.0 cm, to a reduced area of wetness that covered a 2.2-×2.7-cm area. The patient returned to work as an electrician without needing absorbent gloves, which had prevented him from performing electrical work. Discussion. Following use of TWG, the patient\u27s palmar hyperhidrosis returned to normhidrosis

    Nonverbal language – the weapon of the insurance agent

    Within the insurance process, the person who insures as well as the person who wishes to buy an insurance policy must control well enough the communication techniques. In deed, the insurance is grounded on communication. Various scientific researches showed that most people involved in a business are very careful to what they say and the way they say it. Along with the way we speak, in the insurance field as well as in other many fields we tried to emplasize the necessity of ackowledging and controlling the nonverbal communication techiniques.nonverbal communication, insurance

    Unertan Syndrome Quadrupedality,Primitive Language, and Severe Mental Retardation A New Theory on the Evolution of Human Mind

    The recently discovered “UNERTAN SYNDROME” consists of quadrupedal gait, severe mental retardation, and primitive language. This syndrome can be considered as devolution of human being, throwing a light into the transition from quadrupedality to bipedality with co-evolution of human mind. The genetic nature of this syndrome supports the punctuated evolution during transition from quadrupedality to bipedality. In light of Tan’s psychomotor theory, accentuating the major role of the motor system in human mind, a new theory was suggested for the human evolution. Namely, the unique behavioral trait of man, the emergence of the habitual bipedality with Homo erectus (1.6 million and 250.000 years ago) may be coupled with a resistive mind, which forced man to stand up against the gravitational forces with consequent success in tool making and hunting, using free hands for survival. The second stage in the evolution of modern human beings may be coupled with the emergence of language (circa 40.000 years ago), playing a major role in the origins of human mind

    The role of non-verbal communication in second language learner and native speaker discourse

    It is undeniable that non-verbal signals exert a profound impact on communication. Many researchers proved that people, when they are hesitating, analyze non-verbal signals to comprehend the meaning of a message (Allen, 1999), because they prioritize non-verbal aspects of communication over the verbal ones. The role of non-verbal communication is much more profound when native/non-native discourse is taken into consideration (Allen, 1999; Gregersen, 2007). The aim of the present paper is to analyze non-verbal communication of a native speaker and a second language learner. The main emphasis is put especially on the differences between the non-verbal signals of second language learners and native speakers. Some of these differences may disturb or prevent the interlocutors from conveying a message in learner/native speaker discourse (Marsh et al., 2003) so it is necessary to raise awareness of cultural differences and underline the tremendous role of non-verbal communication in second language learning. Furthermore, the present paper also covers some suggestions for foreign language teachers in order to improve their knowledge of the body language of their learners in the target language and help them to raise awareness of the significance of non-verbal communication in second language discourse

    Biomechanical evaluation of the push-up exercise of the upper extremities from various starting points

    Get PDF
    The purpose of the present research was to evaluate the push-up exercise of the upper extremities in respect of biomechanics, to compare the muscle function, while changing the position of performance and to examine the torso's inclination during the exercise. The result is that the activation of the muscles, apart from the triceps brachii muscle, does not differentiate significantly in any of the positions. Moreover, the elevating the hands above the feet position is not recommended in protocols where the aim is to improve the muscle force because it displays the lowest mean value of vertical force and a low RFD. On the other hand, the standard push-up position is considered to be the most appropriate when the aim is to improve the triceps brachii muscle's force because it displays the highest RFD and the highest activation of this muscle. Finally, the correct body position during this exercise prevents from incorrect and damaging inclinations of the torso. © JPES
