RESUMO

BACKGROUND: Cataract surgery is one of the most common operations in health care. Femtosecond laser-assisted cataract surgery (FLACS) enables more precise ocular incisions and lens fragmentation than does phacoemulsification cataract surgery (PCS). We hypothesised that FLACS might improve outcomes in cataract surgery compared with PCS despite having higher costs. METHODS: We did a participant-masked randomised superiority clinical trial comparing FLACS and PCS in two parallel groups (permuted block randomisation stratified on centres via a centralised web-based application, allocation ratio 1:1, block size of 2 or 4 for unilateral cases and 2 or 6 for bilateral cases). Five French University Hospitals enrolled consecutive patients aged 22 years or older who were eligible for unilateral or bilateral cataract surgery. Participants, outcome assessors, and technicians carrying out examinations were masked to the surgical treatment allocation until the last follow-up visit and a sham laser procedure was set up for participants randomly assigned to the PCS arm. The primary clinical endpoint was the success rate of surgery, defined as a composite of four outcomes at a 3-month postoperative visit: absence of severe perioperative complication, a best-corrected visual acuity (BCVA) of 0·0 LogMAR (logarithm of the minimum angle of resolution) or better, an absolute refractive error of 0·75 dioptres or less, and unchanged postoperative corneal astigmatism power (≤0·5 dioptres) and axis (≤20°). The primary economic endpoint was the incremental cost per additional patient who had treatment success at 3 months. Primary outcomes were assessed in all randomly assigned patients who met all eligibility criteria (missing data considered as failure). We used mixed logistic regression models or mixed linear regression models for statistical comparisons, adjusted on centres and whether cataract surgery was bilateral or unilateral. The study is registered with ClinicalTrials.gov, NCT01982006. FINDINGS: Of the 907 patients (1476 eyes) randomly assigned between Oct 9, 2013, and Oct 30, 2015, 870 (704 eyes in FLACS group and 685 eyes in the PCS group) were analysed. We identified no significant difference in the success rate of surgery between the FLACS and PCS groups (FLACS: 41·1% [289 eyes]; PCS: 43·6% [299 eyes]); adjusted odds ratio 0·85, 95% CI 0·64-1·12, p=0·250). The incremental cost-effectiveness ratio was €10 703 saved per additional patient who had treatment success with PCS compared with FLACS. We observed no severe adverse events during the femtosecond laser procedure, and most of the complications in the FLACS group related to the primary outcome measures occurred during the phacoemulsification phase or postoperatively. INTERPRETATION: Despite its advanced technology, femtosecond laser was not superior to phacoemulsification in cataract surgery and, with higher costs, did not provide an additional benefit over phacoemulsification for patients or health-care systems. FUNDING: French Ministry of Social Affairs and Health.

RESUMO

OBJECTIVE: To demonstrate how bladder ultrasound can be useful in completing morcellation during difficult Holmium Laser Enucleation of the Prostate (HoLEP). As HoLEP has emerged as a standard of care for the treatment of benign prostatic hyperplasia, multiple studies have reported the potentially catastrophic complication of bladder injury during morcellation. This video aims to assist any urologist performing HoLEP by providing step-by-step instruction for using ultrasound to complete morcellation safely. METHODS: Enucleation is performed using a 26-French continuous flow scope, off-set laser bridge with a laser stabilization catheter, and a 550 µm holmium laser fiber. Once the median and lateral lobes have been enucleated, the outer sheath is removed and the nephroscope is inserted to facilitate morcellation. Under dual inflow irrigation, the Piranha morcellator (Richard Wolf, Knittlingen, Germany) is introduced and set to the manufacturer's recommended settings of 1500 rpm. A 3.5-MHz convex abdominal ultrasound transducer (Hitachi Prosound Alpha 7; Hitachi Aloka Medical America, Wallingford, CT) under B-mode is used to visualize the bladder, predominantly in the sagittal orientation. Morcellation proceeds under simultaneous ultrasound and direct cystoscopic guidance. RESULTS: The distended bladder is visualized concurrently with the ultrasound and via the nephroscope as the Piranha engages the adenoma and begins morcellation. Once the adenoma is engaged, the operator then drops their hands to place the morcellator in the center of the bladder. Ultrasound provides real-time feedback as to the location of the morcellator in relation to the adenoma and bladder. CONCLUSION: This video highlights the use of intraoperative bladder ultrasound as a visual aid to assist during the morcellation portion of HoLEP. This proof of concept demonstrates that ultrasound can be an additional tool to utilize during difficult cases when cystoscopic visualization during morcellation is limited.

RESUMO

BACKGROUND: The rates of thromboembolic complications such as deep vein thrombosis (DVT) after venous ablation procedures for symptomatic superficial venous insufficiency are controversial. We sought to describe the risk factors for and incidence of DVT after radiofrequency ablation (RFA) and laser ablation (LA). METHODS: We queried the Truven Health Marketscan Database from 2007-16 for patients who underwent RFA or LA and had a follow-up duplex ultrasound within 30 days of the ablation procedure. The primary outcome was DVT at 7 and 30 days identified by International Classification of Diseases-9 and International Classification of Diseases-10 codes. Multivariable regression was used to evaluate the patient and procedural variables associated with a DVT at 30 days, expressed as odds ratios (ORs) with a 95% confidence interval (95% CI). Patients and procedures with a previous DVT diagnosis were excluded. RESULTS: A total of 256,999 patients underwent 433,286 ablation procedures: 192,195 (44.4%) RFA and 241,091 LA. Of these, 8,203 (1.9%) had a newly diagnosed DVT within 7 days and 13,347 (3.1%) within 30 days of the procedure. The incidence of DVT decreased over the study period. LA (2.8%) demonstrated a lower incidence of DVT at 30 days compared with RFA (3.4%), P < 0.001. On multivariable regression, LA (OR, 0.82; 95% CI 0.80-0.85) was again associated with a decreased risk for 30-day DVT, as was female gender (OR, 0.74; 95% CI, 0.71-0.77), and sclerotherapy performed on the same day (OR, 0.91; 95% CI, 0.85-0.98). A diagnosis of peripheral artery disease (OR, 1.23; 95% CI, 1.16-1.31) and concomitant stab phlebectomy (OR, 1.43; 95% CI, 1.37-1.49) was associated with an increased risk of DVT within 30 days. CONCLUSIONS: The incidence of newly diagnosed DVT within 30 days of an ablation procedure was 3.2%. The risk for DVT decreased in recent years, and LA was associated with an 18% decreased risk compared with RFA.

RESUMO

BACKGROUND: Endovenous thermal ablation has become the procedure of choice in the treatment of superficial venous reflux disease. The current armamentarium of devices and techniques aimed at the elimination of saphenous reflux offers surgeons and interventionalists a variety of treatment options; however, there is a lack of data comparing the safety of these products. The most concerning complication after endovenous thermal ablation is endothermal heat-induced thrombosis (EHIT) due to the risk of progression to deep venous thrombosis. This study aimed to compare the incidence rate of EHIT between radiofrequency ablation (RFA) and endovenous laser therapy (EVLT). METHODS: This was a single-center, office-based, retrospective study over the course of 5 years, in which 3,218 consecutive patients underwent 10,029 endovenous saphenous ablations. The patient cohort was 66.2% female, with an average age of 61.9 years. At the time of each individual intervention, 24, 212, 3,620, 4,806, 200, and 1,167 patients had Clinical-Etiology-Anatomy-Pathophysiology disease 1, 2, 3, 4, 5, and 6, respectively. RESULTS: There was a total of 3,983 EVLT and 6,091 RFA procedures. The most common vessel treated was the great saphenous vein, 63.6% of the time, followed by the small saphenous vein (25.6%), accessory saphenous vein (6.1%), and perforator vein (4.6%). There were 186 cases of EHIT, with 137 (73.6%) identified as type 1 as per the Kabnick classification. Endovenous ablation performed via RFA resulted in significantly more cases of EHIT than of EVLT (109 vs. 77; P = 0.034; odds ratio = 1.52), which was confirmed by a multivariate analysis. CONCLUSIONS: In the largest single-center study of endovenous saphenous ablations to date, RFA was shown to pose a significantly higher risk of EHIT than of EVLT.

RESUMO

Objective: To describe the chronological features of choroidal neovascular membrane (CNV) development subsequent to accidental firing of diode laser into the eye of a young female during hair epilation. Methods: Descriptive case report. Results: The patient presented one week after the laser injury to a local ophthalmologist complaining of RE (right eye) blurred central vision. Snellen's visual acuity (VA) was 6/ 7.5. Optical coherence tomography (OCT) showed focal disruption of the ellipsoid and the interdigitation zones. Four weeks later, she presented with worsening symptoms and RE VA 6/ 15. Funduscopy revealed a perifoveal grayish lesion with adjacent retinal hemorrhage, which, on fluorescein angiography, was leaking, compatible with CNV. OCT showed a dome-shaped sub-retinal pigment epithelium lesion with extension into the subretinal space and little subretinal fluid. The patient was treated with one intravitreal bevacizumab injection. There was rapid regression of the CNV and improvement of VA to 6/ 7.5 at one-month visit and to 6/ 6 at 6-month visit. Conclusion: All the laser procedures should be conducted with intensive care for both the patient and the laser surgeon since inadvertent effects are constantly being reported due to lack of adherence to safety measures.

RESUMO

OBJECTIVE: To report long-term safety and efficacy data on middle lobe only-transurethral resection of the prostate (TURP) (MLO-TURP). MATERIALS AND METHODS: We evaluated: (1) efficacy: International Prostate Symptom Score, Quality of Life, peak flow rate (Qmax), postvoid residual urine, International Index of Erectile Function and ejaculatory function, which was assessed by the Male Sexual Health Questionnaire. Men were evaluated at 1 month, 6 months, and yearly thereafter. RESULTS: A total 312 men (mean age 61.3 ± 8.6) with significant lower urinary tract symptoms (n = 147) or urinary retention (n = 175 were treated with MLO-TURP from 2005 to 2017. Mean baseline prostate volume was 79.8 g (30-178 g); mean baseline intravesical-prostatic protrusion was 13.6. Improvements in International Prostate Symptom Score, Quality of Life, Qmax and postvoid residual urine were durable throughout the study period. There was no difference in outcomes between monopolar and bipolar MLO-TURPs. Postoperatively, the incidence of ejaculatory dysfunction was 2.6% (N = 8) and there was 1 case of new onset ED (0.3%). There were modest improvement in bother due to ejaculatory function (baseline: 2.4 and at 5 years: 1.27). CONCLUSION: MLO-TURP is a safe and effective treatment for men with lower urinary tract symptoms. Patients experience long-term improvement of symptoms and preserve antegrade ejaculation. In select men with prominent middle lobes, MLO-- should be considered a therapeutic, ejaculation-sparing option.

RESUMO

BACKGROUND: In this analysis, we aimed to systematically compare the complications which were associated with femtosecond laser-assisted cataract surgery (FLACS) versus the conventional phacoemulsification surgery (CPE). METHODS: Commonly used search databases, specifically MEDLINE, Cochrane Central, EMBASE, and http://www.clinicaltrials.gov were carefully searched for English publications comparing FLACS versus CPE. The selected endpoints which were assessed included incomplete capsulotomy, anterior capsulotomy tag, anterior capsule tear, posterior capsule tear, injury to the descemet's membrane, zonular dialysis, vitreous loss, macular or corneal edema, and elevated intra-ocular pressure. Statistical analysis was carried out by the latest version of the RevMan software (version 5.3) and represented by risk ratios (RR) with 95% confidence intervals (CI). RESULTS: A total number of 7156 participants were included. Three thousand five hundred and fifty four (3554) participants were assigned to the FLACS group. The risks for incomplete capsulotomy, anterior capsulotomy tag, and anterior capsular tear were significantly higher with FLACS (RR: 22.42, 95% CI: 4.53-110.82; P = 0.0001), (RR: 33.07, 95% CI: 6.53-167.56; P = 0.0001) and (RR: 4.74, 95% CI: 2.59-8.68; P = 0.00001) respectively. The risks for macular/corneal edema (RR: 2.05, 95% CI: 1.18-3.55; P = 0.01) and elevated intra-ocular pressure (RR: 3.24, 95% CI: 1.55-6.78; P = 0.002) were also significantly higher with FLACS. However, the risks for impaired descemet's membrane (RR: 0.95, 95% CI: 0.61-1.47; P = 0.80), zonular dialysis (RR: 0.40, 95% CI: 0.06-2.72; P = 0.35), vitreous loss (RR: 0.09, 95% CI: 0.01-1.63; P = 0.10) and posterior capsular tear (RR: 1.45, 95% CI: 0.23-9.16; P = 0.69) were not significantly different. CONCLUSIONS: The current results showed that FLACS did not improve intra/post-operative complications in comparison to CPE. Further larger studies should confirm this hypothesis.

RESUMO

Background: Thermal ablation is a minimally invasive technique that is gradually acknowledged as an effective alternative to surgery to treat thyroid nodules. Two main techniques have been described: radiofrequency (RFA) and laser ablation. Objective: To evaluate the safety and efficacy of the two main techniques (RFA and laser ablation) for the treatment of benign thyroid nodules. Patients: This bicentric retrospective study included 166 consecutive patients, who received clinical, biological and ultrasound evaluations for thyroid nodules, from October 2013 to November 2017. Methods: One of the two techniques was proposed if a nodule was proven to be benign after fine needle aspiration cytology or micro-biopsy. Adverse events and outcomes (symptoms, nodule reduction) were assessed at 6 weeks and 6, 12, and 18 months after treatment. Results: One hundred and eighty-nine nodules (mean size 17.5 ± 16.9 mL, 86.1% palpable) were treated by RFA (n = 108 (57.1%)) or laser ablation (n = 81 (42.9%)) in 166 patients (80.1% women, mean age 51.7 years). Two cases of transient recurrent laryngeal nerve palsy, one hematoma, and two successfully drained abscesses (5/166 = 3%) were observed. Clinical symptoms improved significantly in the two groups (anterior cervical discomfort -83.6%, esthetic complaints -84.9% and dysphagia -86.4%). Nodule volume (mL) decreased significantly (baseline vs. 18 months) from 20.4 ± 18.6 to 5.8 ± 6.6 (-75%) in the RFA, and from 13.6 ± 13.3 to 3.4 ± 4.1 (-83.9%) in the laser ablation groups. Conclusions: Transient but potentially serious adverse events were reported in 3% of patients. A significant volumetric reduction was achieved with both techniques, regardless of nodule's characteristics, at 18 months.

RESUMO

Periocular ecchymosis is a rare finding with various, sometimes life-threatening pathologies. We report the case of a 48-year-old woman who presented with bilateral periocular ecchymosis after laser removal of xanthelasma palpebrarum. Her medical history was unremarkable. Amyloidosis could be excluded by histopathology. We suggest that periocular ecchymosis is a rare adverse event after minor (laser) surgery of the eyelids and discuss the possible pathogenesis and differential diagnoses.

RESUMO

PURPOSE: We have previously reported that lamellar dissection of the cornea transects stromal nerves, and that regenerating neurites form a dense net along the surgical plane. In these experiments, we have disrupted the stromal nerve trunks in situ, without incising the cornea, to determine the regeneration events in the absence of a surgical plane. METHODS: Thy1-YFP mice were anesthetized and in vivo images of the corneal nerves were obtained with a wide-field stereofluorescent microscope. A far infrared XYRCOS Laser attached to 20X objective of an upright microscope was used to perform in situ transection of the stromal nerves. 3 types of laser transections were performed (n = 5/group): (i) point transection (a single cut); (ii) segmental transection (two cuts enclosing a segment of nerve trunk); and (iii) annular transection (cuts on all nerve trunks crossing the perimeter of a 0.8 mm diameter circular area centered on the corneal apex). Mice were imaged sequentially for 4 weeks thereafter to assess nerve degeneration (disappearance or weakening of original fluorescence intensity) or regeneration (appearance of new fluorescent fronds). Beta-3-tubulin immunostaining was performed on corneal whole-mounts to demonstrate nerve disruption. RESULTS: The pattern of stromal nerves in corneas of the same mouse and in corneas of littermates was dissimilar. Two distinct patterns were observed, often within the same cornea: (i) interconnected trunks that spanned limbus to limbus; or (ii) dichotomously branching trunks that terminate at the corneal apex. Point transections did not cause degeneration of proximal or distal segment in interconnected trunks, but resulted in degeneration of distal segment of branching trunks. In segmental transections, the nerve segment enclosed within the two laser cuts degenerated. Lack of beta-3 tubulin staining at transection site confirmed nerve transection. In interconnected trunks, at 4 weeks, a hyperfluorescent plaque filled the gap created by the transection. In annular transections, some nerve trunks degenerated, while others regained or retained fluorescence. CONCLUSIONS: Interconnected stromal nerves in murine corneas do not degenerate after in situ point transection and show evidence of healing at the site of disruption. Presence or absence of a surgical plane influences corneal nerve regeneration after transection.

RESUMO

BACKGROUND: There are many postprocedure skin care options, but no consensus on the best formulation to optimize healing. Silicone gels have only been used to treat keloids and hypertrophic scars and typically applied after the wound has healed. This study compared the healing response after fractional ablative erbium laser resurfacing with a petrolatum-based ointment and a silicone gel. METHODS: A randomized, open-label, split-face study was performed. Ten subjects underwent Erbium:YAG (Sciton) fractional laser resurfacing. Patients were randomized to apply a petrolatum-based gel or a silicone gel (Stratacel® ; Stratpharma) on either the right or left side of the face. Subjects applied the products twice a day for 7 days and were evaluated in person 7, 30, and 60 days postprocedure. Subjects reported on the overall general aesthetic outcome, perceived pain, itch, and tightness via questionnaires using the Global Aesthetic Improvement Scale and the Wrinkle Severity Rating Scale (WSRS). RESULTS: All subjects healed without complications. By day 60, there was no difference in signs and symptoms of healing between the two different dressing approaches. However, patients treated with the silicone gel had less post-treatment erythema and hyperpigmentation. CONCLUSIONS: A novel silicone gel resulted in reduced signs of erythema and hyperpigmentation postprocedure, without an increase in adverse events. Additionally, the silicone gel dries to form a thin, full contact film and can be covered with sunscreen or cosmetics once dry. This new silicone gel presents a good option for postprocedure care after ablative fractional laser resurfacing.

RESUMO

BACKGROUND: There is a paucity of evidence comparing oncological and voice outcomes between T2a and T2b glottic squamous cell carcinoma (SCC) patients treated with transoral laser microsurgery (TLM). This study identified functional and oncological outcomes in this cohort. METHODS: Retrospective review of prospectively collected data of patients treated with TLM for T2 glottic SCC from 2003 to 2017. RESULTS: In total, 75 patients were included. Five-year local control rates were significantly different between T2a and T2b patients (75.2% vs 57.0%, p = 0.022). There was no difference in five-year survival between patients with T2a disease and T2b disease (69.5% vs 73.4%, p = 0.627). There was no significant difference in mean VHI-10 scores in the pre-operative period (18.3 vs 21.4, p = 0.409). However, patients with T2b disease had significantly worse perceived voice outcomes post-operatively (6.6 vs 21.3 p = 0.001). Patients with T2a disease saw significant improvements in mean VHI-10 scores following surgery (18.3 vs 6.6, p = 0.000), while T2b patients did not (21.4 vs 21.3, p = 0.979). The overall laryngeal preservation rate was 94.7%, with 11.5% of T2b patients requiring salvage organ sacrifice. CONCLUSIONS: This study highlights positive functional outcomes for T2a glottic SCC. Patients with T2b disease appear to have significantly worse oncological and functional outcomes, including worse voice quality following surgery and higher rates of salvage laryngectomy.

RESUMO

INTRODUCTION: Visible leg veins are a common cosmetic concern treated mostly by 1064 nm Nd:YAG laser that has become the chosen laser therapy for treating all leg veins up to 3 mm in size. The objective of the current prospective study was to evaluate the safety and efficacy of a new 1064 nm diode laser for leg veins and spider veins on the lower extremities. METHODS: A total of 15 female subjects seeking leg veins and spider veins treatment were recruited to this study. The treatment protocol included two treatment sessions 6 weeks apart and two follow-up visits at three and 6 months after the last diode laser treatment. Results were evaluated by photographs and an investigator classification of the treated vascular lesions appearance on five scores scale from 0 (normal) to 4 (severe). RESULTS: Treatment area photos demonstrated improvement in vascular lesions appearance. Average vascular lesions classification was reduced by approximately one score from baseline score of 2.9 (score 3 is moderate) to an average score 2 (mild) at the 3-month follow-up visit. This improved classification sustained also at 6-month follow-up visit, indicating the long-term effect of the treatment impact. No significant or unexpected adverse events were detected in any of the patients as a result of the treatments. CONCLUSIONS: This study has demonstrated that the new 1064 nm diode laser is safe and effective for the treatment of leg vascular lesions on the lower extremities.

RESUMO

PURPOSE: To investigate the safety and effectiveness of preoperative prostatic artery embolization (PAE) in relation to decrease in hemoglobin level, requirement for blood transfusion, length of hospitalization, and procedure-related complications. MATERIALS AND METHODS: Ten consecutive patients who underwent surgery after preoperative PAE were identified from May 2017 to October 2018 (embolization group: holmium-laser enucleation of the prostate [HoLEP] in 6 patients and robotic simple prostatectomy in 4 patients, mean age 72.9 ± 8.7 years, mean prostatic volume 106.5 ± 22.0 mL). For comparison, consecutive patients with a large prostatic volume (≥70 mL) who underwent surgery without preoperative PAE during the same period were enrolled (nonembolization group: HoLEP in 9 patients and robotic simple prostatectomy in 1 patients, mean age 71.2 ± 5.7 years, mean prostatic volume 87.8 ± 26.7 mL). RESULTS: PAE was technically successful in 90% of patients (9/10). The median interval between PAE and surgery was 2 days. The mean hemoglobin reduction was lower (1.40 ± 0.92 g/dL vs 3.07 ± 1.50 g/dL; P = .008) and the median length of hospitalization was shorter (8.5 days vs 11 days; P = .039) in the embolization group than the nonembolization group. The operating time (mean for HoLEP 146 ± 38 min vs 179 ± 59 min [P = .248], mean for robotic simple prostatectomy 223 ± 32 min vs 354 min) and number of blood transfusion (1 patient vs 2 patients; P = .392) were not significantly different between the 2 groups. None of the patients developed any complications except bleeding requiring transfusion. CONCLUSIONS: Preoperative PAE is safe and may reduce blood loss during prostate surgery.

RESUMO

We sought to assess clinical characteristics and pattern of collateral network involvement associated with development of truncal (systematized) versus diffuse/non-truncal (non-systematized) varicose veins (VVs) in patients undergoing endovascular laser photothermolysis for chronic venous insufficiency (CVI). Secondly, we aimed to assess whether the type of VVs influenced the procedural complications of endovascular laser therapy. A total of 508 patients with hydrostatic VVs of the lower limbs who underwent endovenous laser treatment were included, out of which 84.1% (n=427) had truncal VVs (group 1) and 15.9% (n=81) had diffuse (non-systematized) VVs (group 2). Patients with truncal varices were significantly older (47.50±12.80 vs 43.15±11.75 years, P=0.004) and those with associated connective tissue disorders were more prone to present diffuse VVs (P=0.004). Patients in group 1 presented a significantly higher number of Cockett 1 (P=0.0017), Cockett 2 (P=0.0137), Sherman (P<0.0001), and Hunter (P=0.0011) perforator veins compared to group 2, who presented a higher incidence of Kosinski perforators (P<0.0001). There were no significant differences regarding postoperative complications: thrombophlebitis (P=0.773), local inflammation (P=0.471), pain (P=0.243), paresthesia (P=1.000), or burning sensation (P=0.632). Patients with more advanced CEAP (clinical, etiologic, anatomic, pathophysiologic) classes were older (P<0.0001), more were males (39.05 vs 27.77%, P=0.0084), more were prone to present ulcers (P<0.0001) and local hyperthermia (P=0.019), and presented for endovenous phlebectomy after a longer time from symptom onset. In patients with CVI, systematized VVs were associated with a more severe clinical status and a distinct anatomical pattern of perforators network compared to non-systematized VVs, which is more common in advanced stages.

RESUMO

BACKGROUND: In recent years, there was a rise in ocular injuries secondary to cosmetic laser-assisted hair removal. PURPOSE: To assess the level of adherence to optical safety guidelines during laser-assisted hair removal performed by nurses or physicians in private practice. METHODS: A cross-sectional study was conducted at thirty-one private laser-assisted hair removal clinics. An electronic random number generator using a cluster random sampling technique was used to select the clinics. The Alexlazr™ (Candela Corp.) device operator's manual checklist was modified to collect data from laser device operators and patients by surveying the laser rooms, interviewing the patients, and observing the treatments. RESULTS: Ninety-four patients treated by different service providers were included from 31 private centers. All treatment sessions were delivered by trained nurses. Only 9.5% had acceptable adherence to optical safety guidelines during hair removal treatment, while the majority (90.5%) of service providers were poorly adherent. None of the providers achieved excellent adherence to optical safety guidelines. The item with the least adherence was the lack of non-reflective floors inside laser rooms in 72.3% of centers. All service providers were familiar with the laser system controls and emergency shutdown (100% adherence). CONCLUSION: There is a significant deficiency in the safety precautions at laser-assisted hair removal centers that can result in devastating ophthalmic injuries. Companies providing laser-assisted hair removal machines should be involved in aiding these centers to implement safety procedures.

RESUMO

BACKGROUND: Due to concerns regarding maternal and fetal safety and the absence of evidence to the contrary, laser treatment during pregnancy has traditionally been limited to situations of absolute necessity. OBJECTIVE: This review seeks to examine the available evidence to determine the safety of laser therapy during pregnancy. METHODS: Medical databases were searched for relevant reports from all specialties regarding the use of lasers during pregnancy from 1960 to 2017. A legal case review was also performed. RESULTS: Twenty-two publications in the literature reported the use of various laser wavelengths in 380 pregnant women during all trimesters. Other than 1 case of premature rupture of membranes questionably related to the laser treatment, there were no cases of maternal or fetal morbidity or mortality, premature labor, or identifiable fetal stress. CONCLUSION: The available evidence, limited to low evidence level case reports and series, indicates cutaneous laser treatment during pregnancy is safe for both mother and fetus. Furthermore, laser physics and optics dictate there should theoretically be no risk of fetal laser exposure from commonly used cutaneous lasers.
