RESUMEN
We describe two cases of ocular complications secondary to Diode laser assisted eyebrow epilation. Both included patients were women who underwent an eyebrow epilation procedure with Diode laser. A few hours after the procedure they started complaining with photophobia and blurred vision. They were diagnosed with anterior acute uveitis and treated with topical steroids and mydriatics. During the follow-up the presence of sequelae derived from the laser procedure (mydriasis and corectopia in both patients, cataract in the second one) was confirmed. Laser hair removal of the eyebrows can induce irreversible eye damage. Complete and reliable information regarding the potential side effects of this procedure and proper use of appropriate safety devices is mandatory. We point out the importance of the potential ocular side effects associated with these cosmetic devices.

SUMMARY: Laser photobiomodulation (laser PBM) is known to be able to accelerate burn wound healing in the animal model; however little evidence exists on the action of laser PBM on the expression of important proteins in wound healing in the animal model, such as VEGF and TGF-ß1. The aim of this study was to carry out a systematic review in order to analyse the effect of laser PBM on VEGF and TGF-ß expression during burn wound repair in the animal model. A systematic review was carried out of the EMBASE, PubMed/ MEDLINE and LILACS databases. The studies included were preclinical studies that analysed the action of laser PBM on the expression of VEGF and TGF-ß (1, 2, 3) during burn wound repair in the animal model. The SYRCLE risk of bias tool was used. Random effect models were used to estimate the combined effect. Increased VEGF expression was observed with the use of laser PBM at 4.93 J/cm2 per point in the first two weeks after induction of the burn wound, with greater size of effect in the second week (SDM = 5.72; 95% CI: 3.14 to 8.31, I2 = 0 %; very low certainty of evidence). We also observed that the effect of laser PBM on TGF-ß1 expression was greater than in the control in the first week (SDM = -0.45; 95% CI: -1.91 to 1.02, I2 = 51 %; very low certainty of evidence), but diminished in the third week after induction of the lesion (SDM = -2.50; 95% CI: 3.98 to -1.01, I2 = 0 %; very low certainty of evidence). Laser PBM has an effect on TGF-ß1 and VEGF expression, promoting burn wound repair in the animal model.
RESUMEN: Es sabido que la fotobiomodulación por láser (FBM láser) puede acelerar el proceso de curación de heridas por quemadura en modelo animal, sin embargo aún se carece de mayor evidencia sobre la acción de la FBM láser en la expresión de proteínas importantes en el proceso de curación de heridas en modelo animal, como VEGF y TGF-ß1. Así, el objetivo de este estudio fue realizar una revisión sistemática a fin de analizar el efecto de la FBM láser sobre la expresión de VEGF, TGF-ß durante el proceso de reparación de heridas por quemadura en modelo animal. Se realizó una búsqueda sistemática en las bases de datos EMBASE, PubMed/MEDLINE y LILACS. Se incluyeron estudios preclínicos que analizaron la acción de la FBM láser en la expresión de VEGF, TGF-ß (1, 2, 3) durante el proceso de reparación de heridas por quemadura en modelo animal. Se utilizó la herramienta de riesgo de sesgo SYRCLE. Se utilizaron modelos de efectos aleatorios para estimar el efecto combinado. Observamos aumento de la expresión de VEGF con el uso de FBM láser 4.93 J/cm2 por punto, en las dos primeras semanas tras inducción de la herida por quemadura, con mayor tamaño de efecto en la segunda semana (SDM = 5,72; IC del 95%: 3,14 a 8,31, I2 = 0 %; certeza de la evidencia muy baja). También se observó el efecto de la FBM láser en la expresión del TGF- ß1 que fue mayor que el control en la primera semana (SDM = - 0,45; IC del 95%: -1,91 a 1,02, I2 = 51 %; certeza de la evidencia muy baja), disminuyendo en la tercera semana tras inducción de la lesión (SDM = -2,50; IC del 95%: -3,98 a -1,01; I2 = 0 %; certeza de la evidencia baja). La TFB por láser ejerce influencia en la expresión de TGF-ß1 y VEGF favoreciendo el proceso de reparación de heridas por quemadura en modelo animal.

Objective: The current study aimed to evaluate the effect of diode laser irradiation (980 nm) and warm air drying (50°C) on shear bond strength between Lithium di-silicate (IPS e.max; Ivoclar) and human dentin using both (Etch & Rinse) adhesive, Adper™ Single Bond 2 (3M ESPE) and (Self-etch) adhesive, Single Bond UniversalTM(3M ESPE) before adhesive polymerization. Material and Methods: 54 sound lower molars were sectioned to obtain flat dentinal surfaces. Specimens were divided into 2 equal groups (n=27): Group 1 (ER) and Group 2 (SE) according to bonding approach. Each subgroup was subdivided according to dentin surface treatment into 3 equal subgroups (n=9): Control (Co), Diode laser irradiation (L) and Warm air drying (W). All specimens were adhesively cemented to IPS e.max® CAD discs using RelyX™ Ultimate Clicker™(3M ESPE) resin cement. Samples were then subjected to pre-loading in a thermodynamic manner. All samples were tested for shear bond strength using computer-controlled material testing machine. Data analysis was performed using two-way (ANOVA) (p< 0.05) followed by pair-wise Tukey's post-hoc tests. Results: In (SE) group, the subgroup (W) had the highest shear bond strength values followed by (Co) subgroup and the least was (L) subgroup with statistically significant difference. As for (ER) group, the subgroup (W) had the highest shear bond strength values followed by (Co) subgroup and the least was (L) subgroup with no statistically significant difference. Conclusion: Warm air drying for (SE) bonding approach increased shear bond strength of Lithium di-silicate to human dentin and can be introduced as a new effective protocol.(AU)

Objetivo: Comparar la efectividad de las terapias de sensibilización dental que usan láser diodo 940 nm y nitrato de potasio en pacientes con síntomas de hipersensibilidad dental (HD). Métodos: Este ensayo clínico aleatorizado incluyó 30 pacientes quienes habían recibido previamente terapia periodontal básica y presentaban recesiones gingivales clases I y II (Miller 1985) con síntomas de HD. La muestra fue asignada aleatoriamente a los dos grupos. Al primero (n=15) le fue aplicado láser 940 nm por 90 segundos en la superficie de la recesión, y se les suministró un tubo de glicerina para ser aplicado diariamente y evitar la generación de sesgos. El segundo grupo (n=15) recibió láser inactive como placebo y se le suministró un gel desensibilizante que contenía nitrato de potasio 0,5 g para aplicar dos veces al día durante 14 días. Se realizaron controles a los 15 minutos, 8 días, 15 días y 4 semanas. Los datos obtenidos se registraron en una table en Excel. Se emplearon U de Mann Whitney U y t Student para comparar los grupos (p=0,05). Resultados: Todos los pacientes del estudio mostraron reducción de la HD, diferencias que fueron estadísticamente significativas (p<0,01) entre los dos grupos intervenidos. Conclusiones: Ambos, el láser diodo y el nitrato fueron efectivos en el manejo posterior a la terapia periodontal para el manejo de la HD. Sin embargo, las diferencias fueron mayores para el grupo de terapia con láser.
Purpose: To compare the effectiveness of two dental desensitization therapies, 940nm laser diode and potassium nitrate, in patients with dental hypersensitivity (DH) symptoms. Methods: This randomized clinical trial included 30 patients who initially underwent basic periodontal therapy and presented gingival recessions Class I and II (Miller 1985) with symptoms of DH. Subjects were randomly assigned into two groups. The first group (n = 15) received laser 940 nm application for 90 seconds on the surface of the recession and were given a tube of glycerin to be applied daily in order to avoid generating bias. Patients in the second group (n = 15) were exposed to inactive laser simulating the actual application of the laser, and they were given a desensitizing gel containing 0.5 g of potassium nitrate to be applied twice daily during 14 days. Controls were carried out at 15 minutes, 8 days, 15 days, and 4 weeks. Data obtained were filled out in an Excel table. For comparison between groups the Mann Whitney U and t student tests were used (p=0.05). Results: All patients involve in the study experienced reduction in DH (p<0.01) and differences between the two interventions performed. Conclusions: Laser and nitrate therapies were effective to manage DH after basic periodontal therapy. However, a statistically significant higher sensitivity reduction was observed in laser therapy group.

OBJECTIVE: To present the feasibility of photoselective vaporization of the prostate (PVP) with of a new diode laser-resection system. Surgical treatment of benign prostatic hyperplasia (BPH) is constantly evolving. Laser techniques are increasingly used in prostates of large size. METHODS: A prospective study was performed to evaluate operative data and patient outcomes with PVP using high-power diode laser (HPD) and a novel quartz-head fiber with shovel shape in patients with prostate>80mL. Demographic data, operative time, hemoglobin loss, operative results (IPSS, quality of life (QoL), Qmax, post void residue (PVR), IIEF-5 and micturition diary) and complications following Clavien-Dindo classification are described. RESULTS: Thirty-one patients were included in the study. Sixteen (51.6%) were on active antiplatelet treatment and 12 (38.7%) had received anticoagulants before surgery. All cases were followed at least 6mo. No intraoperative or postoperative major complications occurred. Three patients (9.7%) had minor complications according to Clavien-Dindo classification. Twenty-seven (87.1%) were discharged on postoperative day one without catheter. There were significant improvements in IPSS, QoL, Qmax and PVR, both at 3 and 6mo (P<.0001), but sexual function according to IIEF-5 showed no differences. Urgency (any grade) increased at 3mo (48.4%; P=.002) and considerably decreased at 6mo (9.7%; P<.0001). CONCLUSION: This pilot experience with shovel shape fiber and HPD is encouraging. It shows that laser-resection is a safe procedure, achieving excellent results in terms of IPSS, QoL and Qmax in large prostates even in high-risk patients. Longer follow-up, comparative and randomized controlled studies are needed to widespread these results.

OBJECTIVE: To evaluate the effectiveness of topical anaesthesia with cocaine versus lidocaine plus adrenaline for outpatient transcanalicular and endonasal dacryocystorhinostomy (TCLDCR) with diode laser under sedation. METHODS: A double blind randomised clinical trial was designed using topical anaesthesia for outpatient TCLDCR in the treatment of adult epiphora. A total of 92 patients were enrolled, and randomly allocated to be operated on under sedation and topical anaesthesia with cocaine 4% pledgets versus sedation and topical anaesthesia with lidocaine 2% plus 1/100.000 adrenaline pledgets. Main outcome measures were postoperative comfort, evaluated by a visual analogue scale, presence of secondary effects (blood pressure, heart rate), and resolution of epiphora, evaluated by Munk's scale and endoscopic control. RESULTS: Patients in both groups reported being comfortable during and immediately after TCLDCR. Visualization of the operative field was adequate, and surgery was successfully completed in all cases. Complications were more common in the cocaine group: Sixteen patients from the cocaine group had high blood pressures, versus 2 patients from the lidocaine group (RR=8). Mean blood loss was 6.09 ml in cocaine group, versus 2.05 ml in lidocaine group (RR=6). Both parameters were statistically significant (p=1,1×10(-9)). There were no cases of postoperative epistaxis requiring nasal packing or hospital admission in any group. Success rate was similar in the 2 groups (86.96% group 1 and 89.13% group 2), after 6 months of follow-up. CONCLUSIONS: The combination of topical lidocaine and adrenaline is more effective for outpatient transcanalicular and endonasal dacryocystorhinostomy than topical cocaine. Patient comfort was adequate in both groups, but high blood pressure and blood loss more common after cocaine.

INTRODUCTION AND OBJECTIVES: Epiphora caused by nasolacrimal drainage system obstruction is the main indication for dacryocystorhinostomy (DCR). So are chronic conjunctivitis and dacryocystitis from the same origin. Nasal endoscopy and the introduction of laser assisted DCR have facilitated the performance of the technique. However, it requires complex and expensive equipment, so there are still supporters of the traditional external procedure. The aim of this work was to study the effectiveness and usefulness of local postoperative care in laser DCR final result. MATERIAL AND METHODS: We studied a group of 96 patients diagnosed with epiphora secondary to stenosis-occlusion of the nasolacrimal duct. Of these, 32 patients underwent surgery in both eyes, making a total of 128 cases. The surgery was performed in a private setting between January 1999 and December 2008. The 128 cases were divided into 2 groups: 59 cases in which between 4 and 6 postoperative cures were given in the 2 months following the surgery, and another group of 69 cases in which a single cure was given approximately 7 days after surgery. The final assessment of the outcome of the intervention was done in all cases between 24-30 months after surgery. RESULTS: In 27 cases out of 128 (79% success), there was a restenosis of tear drainage. No statistically significant differences were found between the 2 groups. CONCLUSIONS: In the sample of patients that were intervened using laser assisted DCR, implementation of postoperative cure was irrelevant in the success of the intervention.

In this work, we studied the effects of C0(2), Nd:YAG and diode lasers on the enamel and dentin of deciduous human teeth. After the irradiations, the samples were duly prepared and set up on metallic bases, covered with gold and examined in the scanning electron microscope. The results showed that the irradiation with the C0(2) mode locked laser with 1.0 W power caused melting and irregularities with small cavities on the surface of the enamel. The irradiated area on the dentin surface appeared circular and well delimited, containing blocks of dentin and cracks. By using the pulsed Nd:YAG laser with 1.0 W mean power and 10 Hz frequency, the enamel surface presented granules of molten enamel, with a typical melting look. The irradiated dentin surface presented a cavity with a margin elevated with granules and holes, and its bottom presented dentinary tubules with globules of melted dentin. Irradiation with the mode locked of diode laser with 1.0 W mean power, showed the formation of a melted and evenly resolidified enamel surface, and the dentin surface presented a block of melted dentin with adjacent regions of normal dentin, evidently with a relatively smooth surface.
El estudio presenta algunos resultados del efecto del láser de C0(2), Nd:YAG y Diodo sobre el esmalte y dentina de dientes deciduos humanos. Después de las irradiaciones, se prepararon las muestras y se montaron sobre bases metálicas, cubiertas con oro y examinadas en el microscopio electrónico de barrido. Los resultados mostraron que la irradiación con el láser C0(2) en modo conmutado con 1,0 W de potencia, provoca fusión e irregularidades con pequeños cráteres en la superficie del esmalte. En la superficie de la dentina, el área irradiada se mostró circular y bien definido, con bloques de dentina y grietas. Con el uso del láser Nd: YAG en el modo pulsado con 1,0 W de potencia media y frecuencia de 10Hz, la superficie del esmalte presentó granulos de esmalte fundido, dándole el aspecto de "melting" (derretido). La superficie de dentina irradiada presentó un cráter con borde elevado con gránulos y agujeros, y su fondo presentó túbulos dentinarios con glóbulos de dentina derretida. La irradiación del láser de Diodo en el modo conmutado con potencia media de 1,0 W, provocó la formación de una superficie de esmalte fusionada y resolidificada uniforme y la superficie de la dentina presentó un bloque de dentina fundida en la regiones adyacentes de dentina normal, mostrando una superficie bastante lisa.
