The Impact

Introduction: As hair removal has become most popular in aesthetics, the management of its side effects is crucial for every practitioner. Available studies describe the effectiveness of the diode laser hair removal for all skin types according to the Fitzpatrick scale independently, but the question of the occurrence of side effects and adverse effects remains unanswered. This study aims to illustrate aspects of side effects for patients of various ethnicities and the impact of those on the effectiveness of the treatment. Methods: The research was carried out in Poland and the United Kingdom from March 2016 to March 2019. 217 people of various ethnic origins were qualified for the study, 206 sessions were completed and statistical analysis was performed. The procedure was performed in the pubic area with diode lasers with a wavelength of 805 nm, minimum peak power of 2100 W and pulse duration between 15 and 400 ms. ET sapphire cooling assisted handle 9 x 9 mm large and pulse energy density between 10 and 100 J/cm2 were used for all treatments. In addition, in order to illustrate the effectiveness of treatments, the subjective and objective analyses of hair loss percentages were indicated. In statistical analysis, the chi-square test for independence was used to evaluate the correlation between the type and severity of side effects and the ethnic origin of patients, the number of treatments, the Fitzpatrick scale and the level of satisfaction. Results: The occurrence of sensitivity depended statistically significantly (P=0.002) on ethnicity. Ethnicity had no significant effect on the occurrence of erythema. The occurrence of hyperpigmentation statistically significantly depended (P<0.001) on ethnicity. The occurrence of burns depended statistically significantly (P=0.001) on ethnicity. The number of treatments had a significant (P=0.012) effect on the severity of side effects occurrence. Among participants who had 6 treatments, only half had side effects, including multiple effects occurring in 9.79% of cases. The occurrence of side effects such as sensitivity and hyperpigmentation did not depend on the number of treatments. However, the number of treatments had a significant impact on the incidence of erythema (P<0.001) and burns (P=0.005). More than half of the respondents (58.33%) had erythema after more than six procedures, whereas in the 6 treatments the erythema occurred only in 6.7% of cases. Conclusion: The treatment with the use of diode lasers for all subjects with different ethnicity and thus the recognized scale according to Fitzpatrick is effective and safe. The occurring side effects are transient and do not impact the effect of the whole therapy.

Abstract Hoerl & McCormack propose that animals learn sequences through an entrainment-like process, rather than tracking the temporal addresses of each event in a given sequence. However, past research suggests that animals form “temporal maps” of sequential events and also comprehend the concept of ordinal position. These findings suggest that a clarification or qualification of the authors’ hypothesis is needed.

Abstract. Summary: Background: We aimed at estimating the agreement between the Medicap® (photo-optical) and Radiometer® (electro-chemical) sensors during exercise transcutaneous oxygen pressure (tcpO2) tests. Our hypothesis was that although absolute starting values (tcpO2rest: mean over 2 minutes) might be different, tcpO2-changes over time and the minimal value of the decrease from rest of oxygen pressure (DROPmin) results at exercise shall be concordant between the two systems. Patients and methods: Forty seven patients with arterial claudication (65 + / - 7 years) performed a treadmill test with 5 probes each of the electro-chemical and photo-optical devices simultaneously, one of each system on the chest, on each buttock and on each calf. Results: Seventeen Medicap® probes disconnected during the tests. tcpO2rest and DROPmin values were higher with Medicap® than with Radiometer®, by 13.7 + / - 17.1 mm Hg and 3.4 + / - 11.7 mm Hg, respectively. Despite the differences in absolute starting values, changes over time were similar between the two systems. The concordance between the two systems was approximately 70 % for classification of test results from DROPmin. Conclusions: Photo-optical sensors are promising alternatives to electro-chemical sensors for exercise oximetry, provided that miniaturisation and weight reduction of the new sensors are possible.
