Title : the effect of intense pulsed light therapy with a wavelength of 560nm in Melasma Pigmentation Repair and Assesed with MASI score and Skin Analyzer

Abstract :

Melasma is a benign yet appearance disturbing in women, typically across Asians. IPL with 560 nm is one energy based therapy that can be used to treat melasma. This study is to examine the effect of Intense Pulsed Light Therapy with a wavelength of 560 nm in melasma pigmentation repair and assessed with MASI score and skin analyzer. This research is a type of analytical experimental research with randomized controlled clinical trials, single bind trials. The number of research subjects was 13 subjects in the control group and 13 subjects in each treatment group, so the total number of subjects was 65 people. The treatment group includes: control, IPL 1 session, IPL 2 sessions, IPL 3 sessions, and IPL 4 sessions. The study included 13 patients in 4 treatment groups and 13 control group patients. Results showed a significant difference in the third session of IPL. (p = x) on the difference in decreasing ASI scores between the treatment and control groups, and decreasing pigmentation parameters in the skin analyzer (p = x). There was a positive correlation between IPL sessions and MASI score (r=x), and a positive correlation between IPL sessions and skin analyzer pigmentation parameters (r= x). There is a high correlation relationship on the decrease in MASI score after the third session of IPL treatment, and there is a sufficient correlation on the decrease in MASI score after the third session of IPL treatment.

Title : Laser in dentistry generally and in prosthodontics particularly: Literature review

Abstract :

Lasers were introduced into the field of clinical dentistry with the hope of overcoming some of the drawbacks posed by the conventional methods of dental procedures. Since its first experiment for dental application in the 1960s, the use of laser has increased rapidly in the last couple of decades. At present, wide varieties of procedures are carried out using lasers. Although soft-tissue laser was initially introduced, but with invention of new-generation laser, it is now widely used on dental hard tissue as well. Commonly used laser in dentistry includes neodymium-yttrium aluminum garnet laser, erbium: yttrium aluminum garnet, CO2, erbium chromium:yttrium scandium gallium garnet, holmium:yttrium aluminum garnet, and diode laser. Introducing lasers into dentistry helped the practitioners to overcome the constraint of conventional procedures. Recently, the foothold of lasers in modern dentistry provided ease, efficiency, specificity, and comfort both to clinicians and patients. This article provides an overview of laser history, lasers wavelength, types and applications of the use of lasers in dentistry. Which the modern practitioner needs to be familiarized with these devices and understand the possibilities and limitations of each device.

Title : LANDMARK VERSUS ULTRASOUND GUIDED TECHNIQUE FOR FEMORAL VEIN CATHETERIZATION IN PEDIATRIC INTENSIVE CARE UNIT

Abstract :

In pediatric intensive care, central venous cannulation is prevalent and necessary. This technique does not, however, come without dangers or difficulties. Even though central venous cannulation has traditionally been performed by anatomical landmarks, ultrasound guidance has essentially superseded the latter because of its superior efficacy and safety profile, at least in adult populations. To compare the ultrasound-guided and anatomical landmark techniques in inserting femoral central venous catheters in critical care pediatric patients. Patients planned to insert a central venous catheter in the pediatric intensive care unit; eighty patients were randomized: 40 were assigned to the ultrasound-guided group and 40 to the anatomical landmark group. In the anatomical landmark group, the traditional method consisted of palpating the femoral artery pulse as a landmark; in the ultrasound-guided group, the Central venous cannulation was inserted using ultrasound guidance. Success at the first at-tempt, overall success in cannulation, number of attempts, and arterial puncture were the variables studied in both groups. Success at the first attempt was significantly higher in the ultrasound-guided group versus the anatomical landmark (57.5% versus 10%, p-value 0.001). Overall successful canulation was also higher in the ultrasound-guided group (97.5%, p-value 0.556), and the incidence of the femoral artery puncture was lower in the ultrasound-guided group (10%, p-value 0.13) without achieving statistical significance. According to this study, cannulation success of the central venous catheter in the femoral vein is highly increased by using ultrasound-guided technique, especially at the first attempt, and this minimizes the rate of arterial puncture complication, so it is superior to landmark technique.
