The amputation level: noninvasive methods and clinical criteria.

Before undergoing amputation of a lower limb, one hundred and forty-six patients suffering from arteriosclerosis were studied with the purpose of finding prognostic indicators of success at the most distal level. The best results were obtained when skin perfusion pressure was above 60 mmHg in diabetics and above 40 mmHg in non-diabetics. Lower limb systolic blood pressure and skin thermometry also proved to be useful. The method proposed might be helpful to the surgeon in choosing the best treatment for the patient. It is a nonivasive procedure which can be easily performed and does not require sophisticated or expensive equipment.

[The importance of the thermometric method for assessing the function of mucoperiosteal flaps in uranostaphyloplasty with/without transection of the neurovascular bundles in the rehabilitation of patients with congenital cleft palate].

The nature and degree of reflow to the mucoperiosteal flaps was evaluated using a distant thermometry of the cleft palate in 67 children under uranostaphyloplasty and in early postsurgical period. In extracting the neurovascular bundles from their channels heat reflow to the palate was more fast and pronounced than with the bundles sectioned.

[Evaluation of the results of lumbar sympathectomy using hemodynamic variables].

In order to evaluate the results of the lumbar sympathectomy, we studied 49 patients in the National Institute of Angiology and Vascular Surgery during two years. The hemodynamic tests were performed the day before and one month after the surgical intervention; they included: skin thermometry, measurement of arterial blood flow and resistance in the foot and in the leg, and reactive hyperemia under photoplethysmographic control. Objectively, it could be seen only an increase in the distal skin temperature and an increase of skin blood flow after this treatment.

[Criteria for assessing the functional state of the oral mucosa following the combined treatment of malignant tumors of the maxillofacial area].

Polarography and thermometry were employed in examination of the buccal mucosa in 62 patients after combined treatment and primary plasty for malignant tumors of the maxillofacial area. Measurements of pO2 and buccal mucosa temperature were found to yield objective data on the function of the accepting bed in restoration surgery for postoperative defects and to be helpful for the prediction of local complications. Preoperative irradiation according to intensive concentrated scheme induces less marked changes in the mucosa, this being of prophylactic value in cases when local complications develop. The possibility of local complications increases when pO2 reduces twofold and lower vs. the initial level before irradiation.

[Total intravenous general anesthesia during radical correction of tetralogy of Fallot].

Three techniques of general intravenous anesthesia were compared, using mathematical parameters of the heart rhythm, hemodynamic and sympathoadrenal system responses, arterial blood Hb saturation with O2 (SaO2) and thermometry. It has been established that anesthesia with dipidolor ensures adequate protection against the operation stress both in patients with tetralogy of Fallot previously subject to interarterial anastomoses and patients with tetralogy of Fallot without anastomoses. Combined fentanyl and ketamine anesthesia ensures an adequate protection against the operation stress only in patients with tetralogy of Fallot without anastomoses. A more marked response of sympathetic autonomous nervous system and hemodynamics in patients with tetralogy of Fallot previously subject to anastomoses is, probably, mediated by a more intensive analgesic sequestration in the lungs in the presence of functioning anastomoses, which attenuates the analgetic effect. Anesthesia in patients with tetralogy of Fallot previously subject to interaortic anastomoses should be performed using higher doses of narcotic analgesics.

[Use of helium-neon lasers in the treatment of postoperative wounds of the pharynx].

This paper presents the results of treatment of post-operative pharyngeal wounds in 54 tonsillectomized patients (residents of the Far North) using a helium-neon laser. The treatment had a significant analgetic and anti-inflammatory effect which was demonstrated by the so-called swallow test, bar-algisimetry, thermometry of the mucosa of the anterior palatine arches and mandibular area, and cytological examination of the exudate from the tonsillar niches. Application of a low energy helium-neon laser in tonsillectomized patients shortens the therapeutic period by 2 days.

[Accommodative hyperemia of the ciliary body as one of the pathogenetic factors in myopia].

Thermometry of 40 eyes before and after visual work at near with different correction of ametropia and tonography of 20 eyes with progressive myopia and 20 eyes with stationary myopia conducted before and after 15-minute reading load under full correction have revealed that visual work at near is accompanied by working hyperemia of ciliary body (rise of temperature in the anterior segment of the eye ball) and hyperproduction of intraocular fluid. In eyes with stationary myopia, hyperproduction is fully compensated by improvement of aqueous outflow from the eye. In eyes with progressive myopia, ophthalmic hypertension takes place because of insufficient improvement of the outflow facility coefficient. It is likely that working hyperemia of the ciliary body and hyperproduction of intraocular fluid under conditions of visual work at near can be realized as a factor of myopization of the human eye in case of a certain predisposition: in eyes with a not fully formed angle of the anterior chamber or in eyes with anomalous development of the angle.

[The enhanced efficacy of specific hyposensitization in patients with recurrent uveitis].

The purpose of a new method elaborated for treatment of allergic inflammation of the eye is to rise effectiveness of treatment and to prevent exacerbation of allergic inflammation by means of increasing the accuracy of determining the therapeutic allergen dilution when conducting specific hyposensitization. This is achieved in the following way: in addition to control, when conducting allergometric titration, the syringe needle is introduced intracutaneously without subsequent administration of the allergen. In respective terms, the thermometry of skin is made in the sites of administration of different allergen dilutions and in the control site. Considering the minimum hyperthermia in the site of administration of the highest allergen dilution as compared with the control site, the therapeutic allergen dilution is chosen. This method of treatment was used in 38 patients (54 eyes) with recurrent uveitis and proved to be highly effective in 34 patients (50 eyes), i.e. in 92%. In remote terms of observation, no further recurrences were recorded in 65% of cases.

Non-invasive measurement of the deep temperature of the temporomandibular joint region.

This study was carried out to non-invasively measure the deep temperature of the temporomandibular joint (TMJ) region at rest and after 100 opening and closing movements of the mandible. Using a transcutaneous probe, we performed deep thermometry by the zero-heat-flow method. A RAM-Pack recording system was employed, and the data were processed by and stored in a microcomputer. In 20 normal male subjects, no differences were observed in the deep temperature of the right and left TMJ regions at rest and after exercise. However, in patients with temporomandibular disorders, the deep temperature of the symptomatic joint was higher than that of the asymptomatic joint. The difference, however, gradually decreased to normal with occlusal splint therapy. Thus, it is clear that the deep temperature of the TMJ region provides useful information about inflammation of the TMJ.

[Current status of hyperthermia for deep-seated tumors].

The current status of hyperthermia for deep-seated tumor is reviewed. Heating methods include external heating, intraluminal heating and interstitial heating, all of which have inherent advantages and disadvantages. Hyperthermia alone has significant effects on deep-seated tumors. The combination of hyperthermia and radiotherapy has been widely applied, resulting in 10-15% complete regression and 10-40% partial regression in the treatment of locally advanced tumors. The response rate of thermoradiotherapy was higher than that of radiotherapy for tumors in the brain, rectum and esophagus in the non-randomized study. The clinical application of thermochemotherapy is increasing and its effect is demonstrated in the prevention and treatment of peritoneal dissemination of gastric cancers. Reports of serious complications are rare. The technology for deep-heating and thermometry, and the new criteria for the assessment of thermotherapy for deep-seated tumors seems a promising new treatment modality.

[The use of hyperbaric oxygenation for the prevention of complications in local plastic operations on the face and neck].

Studied were 37 patients in which defects and deformations of various etiology were corrected using plastic with local tissues excised from face and neck. Polarography, thermography and thermometry proved that 5 sessions of hyperbaric oxygenation (HO) at 1.5 atm. sharply reduced the incidence of complications after the surgery. This effect was accounted for by providing optimal conditions to accelerate the microcirculatory improvement, oxygen transport and tissue utilization. HO decreased the incidence of complications that influence the reconstructive surgery outcome.

[Hyperthermia in cancer research. Historical development, current status of research, future perspectives and differentiation from alternative medical procedures].

Already at the beginning of the 19th century first clinical trials with systemically induced fever were performed on malignant tumors. An intensified research in thermobiology in the sixties of this century gave the rationale for using this modality for cancer treatment. Clinical use of hyperthermia in combination with radiation or chemotherapy begun in the mid of the seventies when a better technique for selective heating of the tumor was used. In the technical development the problem of heating deep-seated tumors was mainly solved. Temperature measurements of the tumor and surrounding tissues are performed with specialized thermometry systems using thin implanted catheters to measure inside the body. 1986 a pilot study was initiated at the Medical Clinic III of the Klinikum Grosshadern to study the effects of regional hyperthermia combined with systemic chemotherapy. This study is aimed on feasibility, toxicity, and tumor response.

[Thermography in the complex examination of patients with temporomandibular joint diseases].

The authors describe the usage of thermovisual investigation for diagnostic and treatment control purposes in patients with the temporomandibular joint pathology. In chronic arthritis exacerbations, traumatic arthritis and arthroses the joint thermographic images are different. Thermometry was performed at distinct points of parotidmusticulatory, submandibular and cervical regions. Normal and pathological thermal gradients were found between symmetrical facial sites.

[Experimental study of forehead temperature in autogenic training].

Thermometry of the forehead and cheeks was done in 35 longtime trainees of Autogenic Training (AT). Results revealed a significant increase in forehead skin temperature rather than the hypothesized decrease. Cheek temperature rose significantly more than forehead temperature. This difference between cheek and forehead temperatures could explain the subjective impression of coolness of the forehead during the sixth standard exercise of Autogenic Training.

[A method of dynamic teplometry].

With the help of the proposed scheme of the unit the dynamics of the thermal losses has been studied. The measurements of the heat flow were taken from the body surface of both sick and healthy people in the area of their organs' projection. It has been found that the loading test, which leads the investigated system out of the state of rest, results in the change of radiation heat losses from the body surface. The heat radiation dynamics is characterised by the parameters of the transient processes different in norm and pathology. Due to this fact it is possible to use the dynamic thermometry data for estimation of the organ functioning and revealing the illness.

Three new applicators for hyperthermia.

A computerized system with automatic treatment parameters control for radiological hyperthermia, called Sapic SV03, is presented. The system has been planned and built by the "Sezione Avionica ed Equipaggiamenti" of the Aeritalia in cooperation with the Radiotherapy Department of the University of Turin. The device is supplied with a multifrequency generator system (915, 433, 2-30 MHz) connected with many kinds of applicators, with a fiber optic system for temperature control and a previsional thermometry system. In this paper the authors presented three new applicators. The first one is a concave parallel microstrip applicator at 433 MHz, with a size 16 x 9 cm; the heating pattern is homogenous until 4 cm of depth. This antenna can be used for the treatment of chest wall recurrences of breast cancer. The second is a 27 MHz inductive ring and the third applicator is a pyramidal antenna ("TEM line") that operates at a frequency around 27 MHz.

[Value of combining the thermal test with laser Doppler measurement of skin hemodynamics. Study of vascular acrosyndromes].

Different exploratory investigations of vascular acrosyndromes have failed to define their physiopathology. Capillaroscopy studies the specific morphologic aspects of certain connective tissue diseases, hemodynamic tests usually determine a global parameter, and those tests investigating cutaneous physiology alone come up against difficulties limiting their diffusion. The laser Doppler flowmeter (LDF) measures global skin flow in a reproducible, continuous simple manner, and was combined with standardized provocation tests during a prospective study to assess its value in angiology. The protocol involved a prospective study of 100 subjects during the winter 1984-1985: 21 healthy volunteers, 11 cases of acrocyanosis, 9 of acrorhigosis, 48 of Raynaud's phenomenon (22 primary and 26 secondary), 11 of connective tissue disease without Raynaud's phenomenon (table I). The LDD test measures skin microcirculation flow continuously in parallel with skin thermometry. Provocation tests included a standardized thermal test (fig. 1); the temperature is automatically reduced to 0 degree C in 15 minutes and then increased to 25 degrees C in 10 minutes in a jar into which the hand and forearm of the patients and any measuring captor are introduced. Respiratory provocation and additional pharmacologic tests were also completed. Interpretation of results involved calculation of the mean skin flow, Dm, pulsatile skin flow, Dp (fig. 2 and 3), at the basal state and then during temperature variations. The reference value of Dm is 2.741 +/- 0.378 V and is decreased in acrorhigosis, acrocyanosis and severe Raynaud's phenomenon. At 0 degrees C the decrease in Dm is 33 +/- 13% in healthy subjects. Specific values for different acrosyndromes and particularly the various types of Raynaud's phenomenon do not exist.(ABSTRACT TRUNCATED AT 250 WORDS)
