    The clinical manifestations and HIV testing was analyzed in 137 patients with condylomata acuminata. A pulsed carbon dioxide laser was used to treat 60 patients and 0.15% podophyllotoxin cream was used in 30 patients. Condylomatous lesions were seen at a high rate (87.6%), and the number of patients testing positive for HIV was comparatively high (8%). The first pulsed laser carbon dioxide treatment gave a cure rate of 81.7% as compared with a 40% cure rate with topical cream (p < 0,001). Scars were noted in 8.3% of patients treated with pulsed carbon dioxide laser. The results of the study suggest that carbon dioxide laser is a safe, effective and easy-to-deliver therapeutic approach for the treatment of condylomata acuminata, and that the autosimultaneous LLLT component of laser radiation in the periphery of the photothermal destruction contributed greatly to this efficacy.

    Low-level laser irradiation was given to the area surrounding the hip joint in 113 cases with congenital dislocation of the hip (27 with luxation, 86 with subluxation), in order to eliminate soft tissue strain around the hip joint during reduction of the dislocation. The patients were all infants below 6 months of age at presentation. Treatment of congenital dislocation of the hip consisted of functional treatment using a Pavlik harness in 107 cases, re-wearing of the harness after horizontal traction in 2 cases, and abduction traction in 4 cases.
    Low-level laser therapy was effective for eliminating soft tissue strain around the hip joint, proving to be useful as a physical therapy procedure prior to the use of the harness. Following laser irradiation, the femoral head could be readily elevated, even during horizontal traction.
    Thanks to the use of low-level laser, which was introduced in 1993, reduction could be conservatively attained in all the patients and no avascular necrosis of the femoral head occurred in any of the cases.
    It is important to make the best attempt to achieve reduction by conservative methods in the treatment of congenital dislocation of the hip. As low-level laser irradiation is nonstimulating, noninvasive, and easy to deliver, and has no adverse effects, it is useful as physical therapy for eliminating soft tissue strain around the hip joint before and after reduction of congenital dislocation of the hip.

    Various biological effects including anti-inflammatory response following low reactive level laser therapy (LLLT) have been described in different studies. The purpose of this study was to evaluate the anti-inflammatory effect of LLLT using 60 mW GaAlAs (830 nm) laser on damaged tissue induced by high reactive level laser treatment (HLLT). Two acquired pigmented nevi of a single person’s face were treated with high reactive level lasers (Ultra Pulse CO2 laser and Q-switched Alexandrite laser). After high reactive level lasers irradiation, one acquired pigmented nevus was exposed to 60 mW GaAlAs laser irradiation, whereas the other nevus was not irradiated and served as control. Both nevi were evaluated with digital photographs, thermography and a questionnaire survey. Compared to the nonirradiated control nevus, LLLT decreased the rubor and calor of the acute inflammation caused by HLLT. LLLT immediately after HLLT (Xenogeneous combined laser treatment) seems to be useful to control acute inflammation caused by HLLT.

    We present herein the combined effect of our specially designed laser, magnetic and microwave therapeutic influence on the physiology of the osteoporosis patient. In our age of improved average life expectancy, even some partial cure of osteoporosis remains as a pressing issue, particularly in the light of the growing number of osteoporosis related fractures with still more rapidly growing costs of treatment which is usually accompanied with no less harmful side effects leading to deterioration in the affected patient’s general quality of life (QOL). The author analyzed 180 cases of osteoporosis patients undergoing treatment in the Clinic from 1999 till 2006. We used bone densitometry data obtained by Dual-Energy-X-ray Absorptiometry (DEXA) as the treatment effectiveness criteria. Without any additional medication, we applied various laser, magnetic and microwave influences to treat the disease. The diagnostics and treatment methodology, developed by the author, is based on the principle of treating the whole body as a system and the organic etiopathogenesis of the specific disease, osteoporosis, in particular. The results of the osteodensitometry have been analyzed in terms of the type of osteoporosis, sex, time of treatment, stage of osteoporosis, and the type of bone tissue. Therapy for osteoporosis in our Clinic leads to a significant increase in bone mineral density (BMD) for all types of osteoporosis, with a substantial increase in the bone mass within a period about six months after the completion of the treatment. The bone-mass increase correlated with the positive dynamics of the bone metabolism markers, namely cross-laps and osteocalcin. Analgesic effects were analyzed according to two scales: the verbal ranking scale and the visual analog scale (VAS). Pain intensity decreased by 75%. None of our patients developed any fresh fractures during the course of 5 years subsequent to the treatment. The combination of the therapeutic strategies and the system itself allows the Clinic provide the best possible medical care for osteoporotic patients, by increasing the bone mass and BMD, reducing the pain syndrome, and substantially reducing the chances of fractures, thus improving the QOL and life expectancy of the osteoporosis patient.

    Phototherapy is, in its broadest sense, the use of light for any kind of surgical or nonsurgical treatment, but it is the athermal and atraumatic therapeutic application of light which is now accepted as the working definition of phototherapy. The early light-emitting diodes (LEDs) were unsuitable for clinical applications because of low unstable output powers, broad wavebands and very high angles of divergence. In the late 1990’s, the Space Medicine Programme in the United States National Aeronautics and Space Administration (NASA), developed the ‘NASA LED’ with much higher output powers, a much narrower divergence and quasimonochromatic output. With the ability to mount multiple LEDs in planar arrays, large areas of tissue can be irradiated in one hands-off session, unlike the time-consuming and therapist-intensive punctal application with laser diodes. These arrays deliver almost laser-like wavelength specificity and with clinically useful penetration depths and intensities, three of the most important considerations when considering cellular targets in the light of the first law of photobiology which states that without absorption, there can be no reaction. In the past few years, LED-based systems have been successfully applied in an increasingly large number of fields, and three major wavelengths have emerged with a good photobiological basis and proven clinical utility: blue, around 415 nm; red, around 633 nm, and near infrared, around 830 nm. Each has its own specific cellular target or targets and biological action spectrum and reaction, but it has become even more clear that no single wavelength can accomplish everything and combination LED therapy has proved necessary for greatest efficacy. The application of LEDs has ushered in a new and exciting era in phototherapy, and offers a versatile and inexpensive therapeutic modality either as a stand-alone therapy, or as an adjunctive approach to enhance the good results of existing surgical modalities.
