RESUMO

This investigation was designed to evaluate the reestablishment of bone-to-implant contact on infected dental implant surfaces following decontamination with an erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser and reconstructive therapy. Three patients presenting with at least one failing implant each were enrolled and consented to treatment with the Er,Cr:YSGG laser surface decontamination and reconstruction with a bone replacement allograft and a collagen membrane. The laser treatment was carried out at a setting of 1.5 W, air/water of 40%/50%, and pulse rate of 30 Hz. At 6 months, all three patients returned for the study. En bloc biopsy samples of four implants were obtained and analyzed. Two patients had excellent clinical outcomes, while one patient with two adjacent failing implants experienced an early implant exposure during the follow-up period. There was histologic evidence of new bone formation with two implant specimens and less bone gain with the others. Despite the small sample size, these were optimistic findings that suggested a positive role of Er,Cr:YSGG laser in debridement of a titanium implant surface to facilitate subsequent regenerative treatment. This investigation provides histologic evidence as well as encouraging clinical results that use of the Er,Cr:YSGG laser can be beneficial for treatment of peri-implantitis, but further long-term clinical studies are needed to investigate the treatment outcome obtained.

RESUMO

INTRODUCTION: The Holmium laser is the most used energy source in flexible ureterrenoscopy (URSf). The Lumenis Pulse 120H® laser has a higher system energy, a higher energy per pulse and a higher repetition frequency in relation to other types of lasers, which offers advantages in the treatment of lithiasis. OBJECTIVE: To analyze the results that we have obtained with the use of the Lumenis Pulse120H® laser in patients treated by intrarenal retrograde surgery (RIRS). As secondary objectives there are: the study of the demographic variables of the patients, the characteristics of the stones and the complications associated with the procedure. MATERIAL AND METHODS: An observational, retrospective study of the first 26 patients treated by RIRS and Lumenis Pulse 120H® laser has been performed in our Service between August 2018 and February 2019. The size of the lithiasis was measured on the simple radiography and the CT, in addition, the volume of the lithiasis was calculated. For the realization of RIRS, 8.5Fr digital flexible ureterorenoscope (Olympus®) and the Holmium Lumenis 120H® laser with 200 micron laser fibers from Lumenis® were used. Statistical analysis was performed with the SPSSv21 system. RESULTS: A total of 26 patients with renal lithiasis have been analyzed. The median age was 55.15 years (40.67-67.05). 57.7% of the patients had prior surgical treatment of lithiasis. Thirteen patients presented the litiasis in the renal pelvis, ten in the Upper Calicial Group (GCS), fifteen in the Middle Calicial Group (GCM) and eighteen in the Lower Calicial Group (GCI). The median of the lithiasic volume was 1826.41 mm3. Our overall success rate was 80.8% (100% success in lithiasis less than 2 cm and 85.7% in lithiasis between 2-3 cm). Five patients presented complications, of which 4 were ClavienII and 1 Clavien IIIb. No significant results were found between the lithiasic size and the presence of complications (p = 0.128). CONCLUSIONS: The use of the Lumenis Pulse 120H®laser is an useful tool for the treatment of kidney stones by RIRS, due to his efficiency in the fragmentation and dusting, taking into account that very large lithiasic masses require, in a high percentage of cases, more than one treatment session.

RESUMO

With improvements in endoscopy and laser technology, flexible ureteroscopy (FURS) has been a viable treatment option for large renal stones. Here, we share our experience of the FURS treatment for renal stones 2 cm or greater.We evaluated 251 consecutive patients who underwent FURS and holmium laser lithotripsy for renal stones 2 cm or greater between January 2015 and April 2019. Stone size was defined as the longest axis on non-contrast computed tomography. Data were retrospectively collected from electronic medical records. Patient demographics, stone clearance rates and perioperative complications were evaluated.There were 165 male patients and 86 female patients with an average age of 46.9 years (range 22-80 years). Mean stone size was 2.7 cm and the average number of procedures was 1.4 (range 1-5). The stone-free rate at the end of the first, second and third procedure was 61.9%, 82.9%, and 89.5%, respectively. The final stone-free rate decreased as stone size grows, and it was only 58.3% for kidney stones larger than 4 cm after an average of 2.3 procedures. The lowest clearance rates were observed in lower calyx calculi (87.2%) and multiple calyx calculi (83.5%). The overall complication rate was 15.1%, and the most common complication was postoperative fever (9.6%). One patient required blood transfusion, owing to postoperative coagulation disorders induced by urosepsis.Single or staged FURS is a practical treatment option for the renal stones sized 2 to 4 cm with acceptable efficacy and safety. Stone clearance rate of FURS treatment is mainly affected by stone size and location.

RESUMO

PURPOSE: To evaluate the clinical efficacy of erbium-doped yttrium aluminium garnet (Er: YAG) laser in the treatment of degree II bifurcation periodontitis. METHODS: Thirty patients(60 teeth) with grade II bifurcation lesions of chronic periodontitis were enrolled in this study. One week after supergingival scaling with ultrasound, the patients were randomly divided into experimental group: subgingival scaling with ultrasound and hand instruments + Er: YAG laser irradiation in periodontal pocket; control group: the contralateral homonymous teeth were treated with subgingival scaling with ultrasound and hand instruments alone. The changes of gingival index(GI), pocket depth(PD), horizontal probing depth (HPD) and attachment loss(AL) were compared between the two groups 12 and 20 weeks after treatment. SPSS 20.0 software package was used for statistical analysis. RESULTS: Periodontal clinical indexes(GI, PD, HPD, AL) of the experimental group and control group were significantly reduced compared with baseline at 12 and 20 weeks after treatment(P<0.05). At 12 and 20 weeks after treatment, PD in the experimental group was (4.03±0.48) mm and (3.43±0.45) mm, (4.82±0.55) mm and (4.27±0.36) mm in the control group, respectively. The reduction of PD in the experimental group was significantly greater than that in the control group (P<0.05). There was no significant difference in HPD between the two groups at 12 weeks after treatment. Twenty weeks after operation, HPD in the experimental group was found to be (3.01±0.34) mm and (3.78±0.29) mm in the control group. The decrease of HPD in the experimental group was significantly greater than that in the control group (P<0.05). GI and AL of the experimental group at 12 and 20 weeks were lower than those of the control group, but the difference was not statistically significant. CONCLUSIONS: Er: YAG laser is safe and effective in the treatment of chronic periodontitis patients with grade II root bifurcation lesions with significant clinical value.

RESUMO

Thulium lasers operate at wavelengths between1940-2013 nm either in a continuous wave or in a pulsed mode, which enables smooth incisions with fast vaporization or effective laser lithotripsy for urolithiasis. Thulium laser enucleation is a minimally invasive and size-independent treatment for benign prostatic hyperplasia (BPH) with excellent long-term results. Since its introduction, several modifications in the technology and surgical techniques have been proposed such as vaporesection, vaporization and enucleation with regard to BPH treatment. Recent developments in the thulium laser technology include the introduction of a super pulsed thulium fiberlaser.  This technique delivers the laser energy through anactive fiber with an absorption maximum in water at awavelength of 1940 µm. Preclinical studies showed asignificantly higher stone fragmentation rate in differentex vivo models compared to the Ho:YAG laser. Another innovative thulium laser that works, as a hybrid laser has yet not been tested clinically, however, will soon be introduced. With the introduction of both new thulium lasers as novel devices, the armamentarium in the field of endourology for lithotripsy and enucleation increases. We here present different thulium lasers and surgical techniques that are possible to perform with each device including the reasons and advantages of each modification.

RESUMO

OBJECTIVE: Prostate enucleation is becoming more relevant within BPH treatment. Nowadays is probably the gold standard for enucleation. Several studies have shown holmium laser as the most frequently used safe and efficient energy source. The long learning curve remains as its major drawback. The current review aims to describe step to step technique at our institutionand describing the rational for its use. METHODS: A detailed description on our  step-to-step Holep technique is provided. We focused on the main differences with other techniques already described highlighting the largest experience reported. RESULTS: None of the published series has shown better results in terms of functional, safety and less complications outcomes on the short and long term. No differences are shown in terms of intraoperative/postoperative blood loss, reoperations, capsular perforations or urethral strictures. Our techniques provides shorter surgical length and improved efficiency than blocking and trilobular techniques. The rates of early continence are 4% vs5-40%. Lastly, improvement in morcellator devices delivered no complications related to that part of the surgery. CONCLUSIONS: Holep is the gold standard technique for prostate enucleation. It provides improved functional and safety outcomes than with other techniques. A standardized and optimized technique is mandatory.

RESUMO

OBJECTIVE: To assess current efficacyand safety of low power HoLEP (Holmium Laser Enucleationof the Prostate) for the treatment of obstructingand symptomatic prostatic adenomas and to identify themechanisms supporting the related clinical advantages. METHODS: A systematic review was conducted usingrelevant databases (Ovid Medline, PubMed, Scopusand Web of Sciences), employing ("low power" OR"high power") AND ("HoLEP" OR "holmium laser enucleationof the prostate") as search terms. Inherent publicationswere selected according to the Preferred ReportingItems for Systematic Reviews and Meta-analyses (PRISMA)guidelines. Additionally, the reference lists of theselected papers were checked manually. RESULTS: We included any kind of study (n=15) dealingwith low power HoLEP because of the scarcity of the resultsobtained with the bibliographic search. Low powerHoLEP seems to be fully comparable to the traditionalhigh power HoLEP in terms of feasibility, efficacy andsafety. An additional clinical advantage of the low powerapproach might be the reduced incidence of postoperativedysuria, with limited intensity and duration, possiblydue to the decreased amount of energy delivered tothe capsular plane with a less aggressive modality, conjugatedwith appropriate technical enucleative choices.The physical rationale of low power HoLEP is discussed. CONCLUSIONS: Low power HoLEP is feasible, safeand effective, and might play a not exclusive role in thereduction of incidence, intensity and duration of postoperative dysuria.

RESUMO

Endoscopic enucleation of the prostate was first described by Hiraoka in 1986, using a monopolar resectoscope. His contribution was largely ignored until Gilling and Fraundorfer published their three-lobe enucleation technique with the Holmium laser in 1998 ,that ended establishing itself as a reliable option for the treatment of HBP, backed by ample scientific evidence. Later on, enucleation performed with other lasers, as well as bipolar energy, have shown concordance in their clinical results. As a result, the term AEEP (anatomic endoscopic enucleation of the prostate) emerged to encompass all these techniques. During the last few years there have been significant advances in two areas: first, technology, with the development of pulse modulation for Holmium generators (MOSES) as well as high-speed morcellators. Second, the development of new surgical techniques that recognize the importance of the early release of the sphincter from the apex of the adenoma during the operation as well as the careful preservation of the external sphincter's mucosa, to avoid early stress incontinence. In this paper,we review the recent evolution of both technology and surgical technique. AEEP has been risen to a new level, reducing operative time significantly, usually under one hour, and radically reducing the incidence of early temporary stress incontinence, and maybe also facilitating the learning curve of AEEP.

RESUMO

OBJECTIVE: To review recent and relevant information regarding the use of high-power (HPL) and low-power (LPL) Holmium:YAG lasers (Ho:YAG) in retrograde intrarenal surgery (RIRS) for lithotripsy. METHODS: A PubMed/Embase search was conducted and recent and relevant papers on Ho:YAG for RIRS were reviewed. RESULTS: Settings for Ho:YAG are pulse energy (PE), pulse frequency (PF), and pulse width. Currently, the majority of LPL can also adjust pulse-width but cannot reach PF as high as HPL, however, the higher energy outputs reached by HPL are rarely useful in lithotripsy. Higher PE might enhance ablation but generates larger fragments and higher retropulsion. Pulse width does not affect energy output but delivers energy for a longer time-length. Dusting and basketing are complementary techniques. Dusting seeks to pulverize stones into particles ≤250 µm avoiding the use of instruments for stone retrieval, whereas in fragmenting, the stones are break into smaller pieces which are then retrieved. Dusting can prevent the use of supplies such as access sheaths and baskets and also prevent the complications related to their use. However, is not always feasible in clinical practice to fully ablate a stone into dust, then the use of this supplies and popcorn technique are helpful for rendering a patient stonefree. The energy gap between HPL and LPL is wide and leaves room for a mid-power laser classification, which can overcome the main drawback of LPL, the expenses of HPL, and still holding its versatility for other procedures beyond stones. CONCLUSIONS: HPL and LPL have similar effectiveness, but long-term cost-effectiveness comparisons are underexplored. Newer HPL would need to be compared to emerging technologies as the thulium fiber, and prove superiority to mid-power laser to determine how powerful is enough for Ho:YAG in the years to come.

RESUMO

Holmium laser has been established asthe gold-standard for the ureteroscopic management of urinary stone disease. However the role of laser inpercutaneous nephrolithotomy (PCNL) varies, as multiple energy sources and lithotripters are available. Currently, lasers are becoming more relevant with the development of several miniaturized PCNL techniques. The purpose of this article is to review the role of laser in percutaneous renal surgery, and whether or not it is the best option for this approach. Discussion points include: the history and background of lasers in urologic surgery, PCNL and its outcomes in the literature, the positives and negatives of lasers versus other lithotripters in several different PCNL techniques, emerging laser technology such as thulium fiber laser, the use of lasers in establishing percutaneous renal access, and laser's role in non-stone percutaneous renal surgery.

RESUMO

RESUMEN Introducción: Al realizar una intervención quirúrgica, el instrumento de corte utilizado cobra especial importancia, pues el mismo está vinculado a los signos y síntomas intra- y posoperatorios y al tiempo de reparación de los tejidos. En respuesta a esto, con el tiempo se han propuesto nuevos instrumentos, particularmente la tecnología láser ha venido sufriendo un avance rápido y significativo y en la actualidad se utiliza para un sinnúmero de tratamientos odontológicos. Al láser se le han atribuido diferentes ventajas en la cirugía estética periodontal: desde facilitar el proceso de hemostasia, hasta la estimulación del proceso de reparación tisular. Sin embargo, es pertinente realizar estudios que demuestren a nivel histológico los cambios que generan en la mucosa oral y obtener información que permita conocer de qué manera influye en el proceso de reparación del tejido. Objetivo: Describir los hallazgos histológicos asociados al corte con láser de Er, Cr: YSGG de 2780 nm en muestras de encía obtenidas mediante gingivectomía. Presentación del caso: Paciente femenina, de 21 años, sistémicamente sana. Asistió a la consulta por presentar por inconformidad estética al sonreír. Se diagnosticó con exposición de banda de encía queratinizada mayor que 4 mm. Como parte del plan de tratamiento se indicó gingivectomía con láser de Er, Cr: YSGG (2780 nm) (Waterlase®, BIOLASE®), el procedimiento se realizó solo bajo anestesia tópica. Se tomaron muestras histológicas de tejido gingival para análisis histológico. Conclusiones: El láser Er, Cr: YSGG (2780 nm) preservó la morfología de los fibroblastos después del corte, no hubo evidencia de carbonización, ni profundización de la lesión térmica en el tejido. Este instrumento fue una herramienta de gran utilidad para la ejecución del tratamiento en este caso. Tuvo ventajas importantes como la ausencia de dolor posoperatorio, buena hemostasia y la reparación epitelial casi completa en tan solo 4 días(AU)


ABSTRACT Introduction: When performing a surgical intervention, the cutting instrument used is especially important, since it is associated with intraoperative and postoperative signs and symptoms and to the time of tissue repair. In response to this, new instruments have been proposed over time, particularly laser technology has been undergoing rapid and significant advancement and is currently used for countless dental treatments. Laser has been attributed different advantages in periodontal cosmetic surgery: from facilitating the hemostasis process, to stimulating the tissue repair process. However, it is pertinent to carry out studies that prove, at histological level, the changes in the oral mucosa and obtain information that allows us to know how it influences the tissue repair process. Objective: To describe the histological findings associated with the Er, Cr: YSGG (2780 nm) laser cut in gum samples obtained by gingivectomy. Case presentation: Female patient, 21 years old, systemically healthy. She attended the consultation for presenting aesthetic dissatisfaction when smiling. She was diagnosed with exposure of keratinized gum band greater than 4 mm. As part of the treatment plan, Er, Cr: YSGG (Waterlase®, BIOLASE®, 2780 nm) laser gingivectomy was indicated. The procedure was performed only under topical anesthesia. Histological samples of gingival tissue were taken for histological analysis. Conclusions: The Er, Cr: YSGG (2780 nm) laser preserved the morphology of the fibroblasts after the cut. There was no evidence of carbonization or deepening of the thermal injury in the tissue. In this case, this instrument was a very useful tool for the performance of the treatment. It had important advantages, such as the absence of postoperative pain, good hemostasis, and almost complete epithelial repair in just four days(AU)

RESUMO

To explore the safety and effectiveness of ureteroscopic holmium laser lithotripsy (UHLL) and ureteroscopic pneumatic lithotripsy (UPL) in the treatment of impacted ureteral calculi (IUC).Clinical data of 280 patients in our hospital from April 2016 to May 2019 were retrospectively collected and analyzed, including 136 cases of UHLL group and 144 cases of UPL group. The general clinical data, operation time, intraoperative bleeding volume, hospital stay, stone-free rate (SFR), and surgical complications were collected and analyzed in 2 group.Compared with UPL group, the operation time of UHLL group was significantly reduced (27.25 ±â€Š8.39 vs 34.32 ±â€Š10.57, P < .05), but the hospitalization cost was significantly increased (9.25 ±â€Š0.75 vs 8.24 ±â€Š0.51, P < .05). In terms of total SFR, the UHLL group was significantly higher than the UPL group (93.38% vs 83.33%, P = .011). For proximal IUC, compared with the UPL group, the SFR of the UHLL group was significantly increased (88.33% vs 70.31%, P = 0.005). For distal IUC, there was no significant difference in SFR (97.37% vs 93.75%, P = .638) between the UHLL group and UPL group. There were no significant differences in the complications of local mucosal injury, hematuria, febrile urinary tract infection, ureteral perforation, and urinary sepsis in the 2 groups (P > .05). However, the UHLL group was significantly lower in stone residual rate than the UPL group (6.61% vs 16.67%, P = .001).This study found that UHLL and UPL are safe and effective in the treatment of IUC, but UHLL has the advantages of shorter operation time and high SFR in the treatment of IUC.

RESUMO

BACKGROUND: Chronic non-specific low back pain (LBP) is gradually increasing among populations worldwide and affects their activities. Recently, the Nd:YAG laser has been presented in the rehabilitation field. OBJECTIVES: This study aims to explore the short-term effects of the Nd:YAG laser on chronic non-specific LBP individuals. METHODS: Thirty-five individuals with chronic nonspecific LBP were included in the study from December 2019 to March 2020. Randomly, they were categorized to Nd:YAG group (n = 18) and sham laser as a control (n = 17) thrice weekly for a 6-week intervention. Modified Oswestry disability index (MODI), pain disability index (PDI), visual analogue scale (VAS), and lumbar flexion range of motion (ROM) have been assessed pre and post-6 weeks of the intervention. RESULTS: Significant improvements were observed in the Nd:YAG group (MODI, P < .001; PDI, P = .007; VAS, P < .001; lumbar ROM, P = .002), whereas the sham group showed no significant changes (MODI, P = .451; PDI, P = .339; VAS, P = .107; lumbar ROM, P = .296) after 6-week intervention. Between-group comparisons showed significant differences in tending toward the Nd:YAG group (MODI, P < .001; PDI, P = .046; VAS, P < .001; lumbar ROM, P = .003). CONCLUSIONS: Regarding the present study outcomes, short-term pulsed Nd:YAG laser (6 weeks) may reduce functional disabilities and pain intensity, and improve the lumbar flexion ROM in patients with chronic nonspecific LBP. Further well-designed randomized controlled studies with large sample sizes should be conducted regarding laser treatment.

RESUMO

Aims: The aim of this study was to investigate the antimicrobial effect of Erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser with and without NaOCl solution. A total of 81 extracted human mandibular premolar teeth were used. Materials and Methods: After root canal preparation and sterilization, the samples were inoculated with E. faecalis for 24 hours. The specimens were divided into 4 experimental groups. Group 1 (n = 25) was irradiated with 2 W laser, group 2 (n = 25) was irradiated with 0.75 W laser in combination with 2.5% NaOCl, group 3 (n = 25) was irrigated with 5% NaOCl and group 4 (n = 6) was not treated. Statistical analysis was performed by using Wilcoxon Signed Ranks, Mann-Whitney U and Kruskal-Wallis H tests. Results: The combination of 0.75 W laser with 2.5% NaOCl regime was found to be just as effective at inhibiting the growth of E. faecalis and sterilization of all root canals as 5% NaOCl irrigation (P > 0.001). The 2 W laser had significant bactericidal effect in infected root canals however it did not eradicate all bacteria. The SEM observations were in accordance with the microbiologic findings. Conclusions: Within the limitations of this laboratory study, NaOCl irrigation improved the antimicrobial effect of Er,Cr:YSGG laser irradiation. When the toxic effects of high percentage of NaOCl was considered, the combination of low-powered laser and low concentration of NaOCl can be used as an effective disinfection method in root canal treatment.

RESUMO

BACKGROUND: To compare clinical effect between Er: YAG and CO2 laser in treatment of oral tumorous lesions. METHODS: A comprehensive search was conducted from 2000 to 2019. The quality assessment was performed by the QUADAS-2 tool (The Cochrane Collaboration, 2011). The clinical value of comparison between Er: YAG and CO2 laser was evaluated by using the pooled estimate of sensitivity and specificity. In addition, sensitivity analysis and bias analysis were applied to ensure the accuracy of the results. RESULTS: Finally, 268 patients were enrolled in 6 studies and ultimately met the eligibility criteria. The Er: YAG and CO2 groups were 141 and 127, respectively. The meta-analysis showed significant difference in success (risk ratio  = 21.29, 95% confidence interval [1.09, 1.52], P = .002; P for Heterogeneity = .99, I = 0%) and time of surgery ((P of heterogeneity = .29, I = 20%, Z = 25.69, P of over effect < .00001). The recurrence and complications of CO2and Er: YAG groups had no difference. CONCLUSION: Er: YAG laser had better effects than CO2 laser in eliminating oral tumorous lesions while it needed longer operation time than CO2 laser.

RESUMO

The global dissemination of the novel coronavirus disease (COVID-19) has accelerated the need for the implementation of effective antimicrobial strategies to target the causative agent SARS-CoV-2. Light-based technologies have a demonstrable broad range of activity over standard chemotherapeutic antimicrobials and conventional disinfectants, negligible emergence of resistance, and the capability to modulate the host immune response. This perspective article identifies the benefits, challenges, and pitfalls of repurposing light-based strategies to combat the emergence of COVID-19 pandemic.
