Abstract
PURPOSE To investigate the clinical efficacy and safety of bipolar coagulation forceps combined with 1% lauromacrogol foam sclerotherapy in the treatment of microcystic lymphatic malformation of tongue. METHODS The clinical data of 16 patients with microcystic lymphatic malformation of the tongue admitted to the Department of Stomatology of Foshan First People's Hospital from April 2017 to April 2020 were retrospectively analyzed, including 7 males and 9 females, aging from 15 months to 21 years. The average age of patients was 8.32±1.21 years. The efficacy and complications of the patients were evaluated. RESULTS All 16 patients were followed up for 6 to 12 months. The clinical response was evaluated as eleven patients (68.75%) for grade Ⅳ, three (18.75%) for grade Ⅲ, two (12.5%) for grade Ⅱ, and the effective rate was 87.5%. Necrosis of tongue mucosa and muscle occurred in 1 patient. CONCLUSIONS Bipolar coagulation forceps combined with 1% lauromacrogol foam sclerotherapy is a minimally invasive, safe and effective treatment for tongue microcystic lymphatic malformation.

Abstract
OBJECTIVE To compare the efficacy and safety of sclerosing agents injected in dorsal veins of rabbit ears. METHODS Sixty ears of 30 rabbits were randomly allocated in: 1% liquid polidocanol, 1% polidocanol foam, 0.2% polidocanol-glucose 70% solution, glucose 75% or 0.9% saline. Outcomes included efficacy (luminal occlusion), complications (phlebitis, neovascularization, ulceration at the puncture site, necrosis and local inflammation) and histology (sclerosis, recanalization vein and surrounding tissues inflammation, blood extravasation, recanalization, lymphangiogenesis, destruction of cartilage and neoangiogenesis). RESULTS Sclerosis was superior in Foam Group (76.9%), but also with 30.7% necrosis (p = 0.003), 46.15% ulceration (p = 0.003), and 69.2% local inflammation (p < 0.0001). Neovascularization were similar. Histology showed 38.5% phlebitis (p = 0.004) and necrosis (p = 0.03) in the foam group. CONCLUSIONS Sclerosis with foam and liquid polidocanol were superior to the other groups, but specially polidocanol foam at the expense of greater frequency of adverse events.

Abstract
OBJECTIVE To report the complications and evaluate the risk factors of elective endoscopic cyanoacrylate injection with lauromacrogol for gastric varices in cirrhotic patients. METHODS A total of 583 elective endoscopic tissue adhesives procedures were performed in 439 patients in our hospital from January 2015 to December 2016. The clinical characteristics and complications were retrospectively collected and evaluated. RESULTS The median age was 56 ± 11 years, and 290 (66.1%) patients were male. The main etiology of liver cirrhosis was hepatitis virus (63.3%). Two hundred fifty-nine (59.0%) patients were classified as Child-Pugh Class A. Bleeding occurred in 44 patients (7.5%) during procedures. Two patients developed distant embolism (0.5%; one pulmonary, one cerebra). In perioperative period, fever was a common complication; however, only 16 cases had high fever and one case had sepsis. Bleeding was observed in 7 (1.2%) patients. Overall incidence of the major perioperative complication was 3.8%. The major postoperative complication rate was 10.4% (60/582, 26 rebleeds, 27 ascites increase, 12 new-onset portal vein thrombosis). The complication-related death was 1.6% (one death from embolism, five deaths from rebleeding, one death from refractory ascites). Injection point was the only factor related to the major perioperative complications [odds ratio (OR) = 1.581, 95% CI, 1.086-2.301; P < 0.05]. Etiology of cirrhosis and injection point were independent risk factors of major postoperative complications (OR = 1.830, 95% CI, 1.005-3.331, P = 0.048; OR = 1.373, 95% CI, 1.089-1.731, P = 0.007). CONCLUSION The incidence of complications after elective endoscopic cyanoacrylate injection with lauromacrogol for gastric varices was low. The injection point was the risk factor for both perioperative and postoperative complications.

Abstract
PURPOSE In Italy, colorectal surgery has been strongly affected with the vast majority (90%) of operations treating benign diseases, with an estimated overall 12-week cancellation rate of 72%. Little is known on how to best manage patients with benign diseases and the consequences this interruption of care will have in post-pandemic times. Proctologic diseases have social, psychological, and healthcare repercussions for their high incidence and great impact on the quality of life. METHODS We decided to treated 10 urgent cases affected from III- and IV-degree hemorrhoids with 3% polidocanol foam in attempt to reduce hemorrhoidal symptoms while waiting for surgery so called "bridge treatment". RESULTS During the follow-up no complications were occurred, and all patients had resolution of bleeding and pruritus with a mean VAS of 1 (range, 0-1). CONCLUSIONS This treatment could reduce the bleeding that is the main symptom from which patients suffer and for which they underwent proctological evaluation and surgery. According to our preliminary experience in the impossibility of accessing the surgery during the COVID-19 pandemic, ST could be considered as the treatment of choice in those patients who are suffering from grade III- and IV-degree hemorrhoids while waiting for surgery.

Abstract
There is an increasing appreciation for the heterogeneity of myeloid lineages in the lung, but relatively little is known about populations specifically associated with the conducting airways. We use single-cell RNA sequencing, flow cytometry, and immunofluorescence to characterize myeloid cells of the mouse trachea during homeostasis and epithelial injury/repair. We identify submucosal macrophages, similar to lung interstitial macrophages, and intraepithelial macrophages. Following injury, there are early increases in neutrophils and submucosal macrophages, including M2-like macrophages. Intraepithelial macrophages are lost after injury and later restored by CCR2+ monocytes. We show that repair of the tracheal epithelium is impaired in Ccr2-deficient mice. Mast cells and group 2 innate lymphoid cells are sources of interleukin-13 (IL-13) that polarize macrophages and directly influence basal cell behaviors. Their proximity to the airway epithelium establishes these myeloid populations as potential therapeutic targets for airway disease.

Abstract
With the development of cross-sectional imaging modalities and the increasing attention being paid to physical examinations, the prevalence of pancreatic cystic neoplasms (PCNs) has increased. PCNs comprise a broad differential spectrum with some PCNs having low or no malignant potential and others having high malignant potential. The morbidity and mortality rates related to major pancreatic surgical resection are high. Long-term surveillance may not only increase the financial burden and psychological stress for patients but also result in a missed malignancy. Minimally invasive endoscopic ultrasound (EUS)-guided ethanol ablation was first reported in 2005. Several other agents, such as paclitaxel, lauromacrogol, and gemcitabine, were reported to be effective and safe for the treatment of PCNs. These ablative agents are injected through a needle inserted into the cyst via transgastric or transduodenal puncture. This treatment method has been substantially developed in the last 15 years and is regarded as a promising treatment to replace surgical resection for PCNs. While several reviews of EUS-guided ablation have been published, no systematic review has evaluated this method from patient preparation to follow-up in detail. In the present review, we systematically describe EUS-guided injective ablation with regard to the indications, contraindications, preoperative treatment, endoscopic procedure, postoperative care and follow-up, evaluation method, treatment efficiency, safety profile, tips and tricks, and current controversies and perspectives.

Abstract
In this study, sulfate radical-based oxidation of an alcohol ethoxylate (AE) was explored by the persulfate (PS)/UV-C process. Poly(oxyethylene)(4)laurylether, commercially known as Brij30®, was used as a model AE. PS/UV-C oxidation of aqueous Brij30® (8-20 mg/L) was performed at initial PS concentrations varying between 0.50 and 6.50 mM and at initial pH values of 3.0 and 6.0. Results indicated that an increase in both initial PS and Brij30® concentrations did not have a significant effect on Brij30® removal efficiency and that Brij30® abatements of more than 90% could be achieved after 60 min of treatment time. Total organic carbon (TOC) removals were significantly improved with increasing initial PS concentrations for both initial pH values. On the other hand, an increase in initial Brij30® concentration had a negative effect on mineralization. By employing the competitive kinetic method, the second-order reaction rate coefficient of Brij30® with the sulfate radical (SO4 •-) was determined as 1.62 × 109 ± 3.5 × 107 M-1s-1. The second-order reaction rate constant of TOC, originating from Brij30® and reaction intermediates, was found to be 9.09 × 105 ± 2.91 × 105 M-1s-1 and 1.13 × 106 ± 0.46 × 106 M-1s-1 for pH values of 6.0 and 3.0, respectively. Toxicity of PS/UV-C treated aqueous Brij30® solutions towards Vibrio fischeri was also investigated to determine the possible toxic behavior of oxidation products.

Abstract
OBJECTIVES We compared the efficacy, safety, and cost-effectiveness of ultrasound-guided percutaneous polidocanol injection and percutaneous ethanol injection for the treatment of benign cystic and predominantly cystic thyroid nodules. METHODS A total of 135 cystic thyroid nodules treated by percutaneous ethanol injection and 136 cystic thyroid nodules treated by percutaneous polidocanol injection were enrolled retrospectively in this study from May 2010 to March 2016. The nodules were followed after 1, 3, 6, and 12 months. Nodule volumes, symptoms scores, and cosmetic scores were assessed before treatment and at follow-up. The therapeutic success rate, safety, and cost-effectiveness between the groups were also compared. RESULTS No significant differences in the reduction of the nodule volume, volume reduction rate, and therapeutic success were observed between the groups with cystic and predominantly cystic thyroid nodules during follow-up (P > .05). Neither the cosmetic scores (P = .59; P = .42) nor the symptom scores (P = .32; P = .73) in the cystic and predominantly cystic nodules were significantly different between the groups at the last follow-up. The complication rates for ethanol were higher than those for polidocanol (P < .05). However, the cost of polidocanol injection was higher than that of ethanol injection for cystic thyroid nodules (mean ± SD, US$97.18 ± US$22.17 versus US$43.36 ± US$5.51; P < .01). CONCLUSIONS Ultrasound-guided percutaneous polidocanol injection can be an alternative for sclerotherapy of cystic or predominantly cystic thyroid nodules. However, its cost was higher than that of percutaneous ethanol injection.

Abstract
RATIONALE Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors involving the gastrointestinal tract. A small percentage of GISTs may cause acute gastrointestinal bleeding, which requires urgent surgical intervention. PATIENT CONCERNS In this case report, we present a 62-year-old male patient with who was hospitalized due to acute bleeding. DIAGNOSES The patient was diagnosed as GIST with low risk. INTERVENTIONS The patient was treated endoscopically with polidocanol sclerotherapy. OUTCOMES The mass was removed completely, and the patient was discharged at day 9 after operation. LESSONS This case indicates that GIST can present as massive upper gastrointestinal bleeding and urgent endoscopic sclerotherapy can be life-saving. The endoscopical intervention may be a good alternative for emergency.

Abstract
Purpose To assess the safety and effectiveness of polidocanol sclerotherapy combined with transarterial embolization using a liquid adhesive agent (n-butyl cyanoacrylate, NBCA) for treatment of extracranial arteriovenous malformations (AVMs). Materials and Methods Twenty-three patients with symptomatic AVMs in the head and neck (6), upper (7) and lower extremity (10) with a mean age of 42 years (range 4–74) treated with polidocanol sclerotherapy were retrospectively assessed. AVMs were classified according to the angiographic morphology of the nidus. There were 2 type I, 6 type II, 6 type IIIa and 9 type IIIb. Arterial embolization using NBCA was performed to reduce arterial flow before sclerotherapy. Polidocanol mixed with contrast material or carbon dioxide was delivered by percutaneous direct puncture. Results Treatment was successfully performed in all patients. In the mean follow-up period of 38 months, symptoms resolved or improved in 20/23 patients (87.0%). AVMs were devascularized 100% in 2 patients, 76–99% in 13, 50–75% in 7 and < 50% in 1. More than 50% devascularization was seen in 22 patients (95.6%). Two (8%) patients had complete remission, 17 (74%) had partial remission and 3 (13%) had no remission. There was no aggravation. Treatment was considered effective (complete and partial remission) in 20 patients (87.0%). Minor complications including localized arterial thrombosis (2) and spontaneously healing skin ulcer (1) were seen in 2 patients (8.7%). There were no major procedure-related complications. Conclusion Polidocanol sclerotherapy combined with transarterial embolization using NBCA is safe and effective for treating extracranial AVMs with an acceptable risk of minor complications.

Abstract
AIM To evaluate clinical and imaging outcomes after ultrasound (US)-guided 3% polidocanol (POL) foam-sclerotherapy of venous malformations (VMs). METHODS We retrospectively evaluated consecutive VM cases over 1.5 years, with 6-month follow-up. US findings were used to classify VMs into four types depending upon extent of anechoic channels, connections to adjacent veins, and dysmorphism. Single or multiple needles were inserted depending upon lesion size, and used to inject up to 8 mL POL per session, every 2 to 4 weeks. We evaluated reduction in pain and swelling, lesion resolution on imaging, and patient satisfaction. RESULTS There were 15, 24, 9, and 5 patients (total 53) with type I, II, III, and IV VMs, respectively. The average number of sessions was 5.3, 4.3, and 4, and the average amount of POL injected was 14.24 mL, 16.1 mL, and 23.2 mL for type I, II, III VMs, respectively. The number of sessions correlated with lesion volume (P < .0001). Imaging showed good resolution in 4/15, 18/24, 6/9, and 4/5 patients respectively with type I, II, III, and IV VMs. Patient satisfaction was not related to lesion type (P = .1). ROC analyses showed cut-off values of 4.9 mL lesion volume, three sessions, and 12 mL POL volume for patient satisfaction. At 6 months, 23 patients having pain had significant improvement (P < .00001). Local (n = 30) and chest pain (n = 2) were the only complications. CONCLUSIONS US-guided sclerotherapy with 3% POL foam is safe and effective. Lesions with up to 50% anechoic areas had better resolution, without correlation with patient satisfaction.

Abstract
AIM To investigate the efficacy and safety of a combination of sufentanil and propofol injection in patients undergoing endoscopic injection sclerotherapy (EIS) for esophageal varices (EVs).
METHODS Patients with severe EVs who underwent EIS with sufentanil and propofol anesthesia between April 2016 and July 2016 at our hospital were reviewed. Although EIS and sequential therapy were performed under endotracheal intubation, we only evaluated the efficacy and safety of anesthesia for the first EIS procedure. Patients were intravenously treated with 0.5-1 μg/kg sufentanil. Anesthesia was induced with 1-2 mg/kg propofol and maintained using 2-5 mg/kg per hour of propofol. Information, regarding age, sex, weight, American Association of Anesthesiologists (ASA) physical status, Child-Turcotte-Pugh (CTP) classification, indications, preanesthetic problems, endoscopic procedure, successful completion of the procedure, anesthesia time, recovery time, and anesthetic agents, was recorded. Adverse events, including hypotension, hypertension, bradycardia, and hypoxia, were also noted.
RESULTS Propofol and sufentanil anesthesia was provided in 182 procedures involving 140 men and 42 women aged 56.1 ± 11.7 years (range, 25-83 years). The patients weighed 71.4 ± 10.7 kg (range, 45-95 kg) and had ASA physical status classifications of II (79 patients) or III (103 patients). Ninety-five patients had a CTP classification of A and 87 had a CTP classification of B. Intravenous anesthesia was successful in all cases. The mean anesthesia time was 33.1 ± 5.8 min. The mean recovery time was 12.3 ± 3.7 min. Hypotension occurred in two patients (1.1%, 2/182). No patient showed hypertension during the endoscopic therapy procedure. Bradycardia occurred in one patient (0.5%, 1/182), and hypoxia occurred in one patient (0.5%, 1/182). All complications were easily treated with no adverse sequelae. All endoscopic procedures were completed successfully.
CONCLUSION The combined use of propofol and sufentanil injection in endotracheal intubation-assisted EIS for EVs is effective and safe.

Abstract
AIM To focus on procedure-related complications, evaluate their incidence, analyze the reasons and discuss the solutions.
METHODS Overall, 628 endoscopic gastric variceal obturation (EGVO) procedures (case-times) with NBC were performed in 519 patients in the Department of Endoscopy of the Third Affiliated Hospital of Sun Yat-Sen University from January 2011 to December 2016. The clinical data of patients and procedure-related complications of EGVO were retrospectively analyzed.
RESULTS In the 628 EGVO procedures, sticking of the needle to the varix occurred in 9 cases (1.43%), including 1 case that used lipiodol-diluted NBC and 8 cases that used undiluted NBC (P = 0.000). The needle was successfully withdrawn in 8 cases. Large spurt bleeding occurred in one case, and hemostasis was achieved by two other injections of undiluted glue. The injection catheter became blocked in 17 cases (2.71%) just during the injection, and 4 cases were complicated with the needle sticking to the varix. Large glue adhesion to the endoscope resulted in difficulty withdrawing the endoscope in 1 case. Bleeding from multiple sites was observed in the esophagus and gastric cardia after the endoscope was withdrawn. Hemostasis was achieved by 1% aethoxysklerol injection and intravenous somatostatin. The ligation device stuck to the varices in two cases during the subsequent endoscopic variceal ligation. In one case, the ligation device was successfully separated from the esophageal varix after all bands were released. In another case, a laceration of the vein and massive bleeding were observed. The bleeding ceased after 1% aethoxysklerol injection.
CONCLUSION Although EGVO with tissue glue is usually safe and effective, a series of complications can occur during the procedure that may puzzle endoscopists. There is no standard operating procedure for addressing these complications. The cases described in the current study can provide some reference for others.

Abstract
OBJECTIVE To evaluate the efficacy and safety of percutaneous polidocanol injection (PPI) in treatment of predominantly cystic thyroid nodules. MATERIALS AND METHODS This prospective study included 111 patients with 122 benign predominantly cystic thyroid nodules inducing pressure symptoms or cosmetic problems. The nodules were randomized to a single aspiration with (n = 61) or without (n = 61) subsequent PPI and followed up after 1, 3, 6, and 12 months. Ten patients (12 nodules) declined to follow up after aspiration in group 2. Nodule volumes, symptoms scores, and cosmetic scores were evaluated before and after treatment. The therapeutic success rate and safety of PPI for treatment of predominantly cystic thyroid nodules were also evaluated. RESULTS In the PPI group, the nodule volumes were reduced from 13.67 ± 9.90 to 2.60 ± 2.66 (p < .001). Therapeutic success rate (nodule volume reduction >50%) was obtained in 57 of 61 (93.44%) nodules in the PPI group, compared to seven of 49 (14.29%) in the aspiration group (p < .001). In the aspiration group, the nodule volume was not significantly reduced. The reduction in symptom scores was significantly higher in the PPI group (from 3.60 ± 1.65 to 1.60 ± 1.19) than in the aspiration group (from 3.62 ± 1.89 to 3.30 ± 1.06) (p < .001, between groups). The reduction in cosmetic scores showed a significant difference between groups (p < .001). In total, 4.92% of patients (3/61) in the PPI group and 85.71% (42/49) in the aspiration group showed recurrence during the follow-up period. There was a significant difference in the recurrence rate between groups (p < .001). No major side-effects occurred. CONCLUSIONS US-guided PPI of benign recurrent predominantly cystic thyroid nodules is effective and safe. PPI is an important alternative to benign recurrent predominantly cystic thyroid nodules.

Abstract
OBJECTIVE To evaluate the clinical efficacy of ultrasound-guided lauromacrogol sclerotherapy for benign thyroid cysts and analyze the factors affecting the efficacy. METHODS Ultrasound-guided lauromacrogol sclerotherapy was performed in 97 patients with a total of 99 benign thyroid cysts. The changes in cystic volume and other thyroid parameters were evaluated at 1, 3, 6, and 12 months after sclerotherapy. According to changes in the cystic volume, the efficacy of sclerotherapy was defined as therapeutic failure (with a volume reduction <50%), treatment success (volume reduction ≥50%) and cure (volume reduction ≥90%). The factors of affecting the efficacy of sclerotherapy was analyzed using COX regression. RESULTS The mean cystic volume at 1, 3, 6 and 12 months after sclerotherapy were reduced from the baseline volume of 12.08∓11.56 cm3 to 5.63∓8.51 cm3, 5.96∓8.42 cm3, 3.80∓5.50 cm3 and 2.85∓3.98 cm3, respectively, with an average cystic volume reduction rate of (70.02∓33.72)%. Therapeutic success was achieved 82 of the 99 cysts (82.83%) and cure was achieved 63cysts (63.64%) at 12 months after the procedure. A second sclerotherapy was performed for 13 cysts which did not show a volume reduction at 1-3 months after the initial procedure. A disease course of over 12 months was an independent risk factor for a second sclerotherapy (23.7% [9/38] vs 6.6% [4/61], OR=4.473 [1.238-16.169], P=0.022). The efficacy of sclerotherapy was related to cystic cavity separation, cystic fluid viscosity, cystic/solid ratio and cystic wall thickness. COX regression analysis revealed that cystic cavity separation (HR=2.25, 95%CI: 1.19-4.25) and cystic fluid viscosity (HR=2.02, 95%CI: 1.19-3.43) were the major factors affecting the treatment efficacy. CONCLUSION Ultrasound-guided lauromacrogol sclerotherapy is effective and safe for treatment of benign thyroid cysts, and the maximal treatment effect can be achieved at 6 months after sclerotherapy and in cases of uncomplicated cysts with non-viscous cystic fluid, no solid cystic cavity separation and a disease course of less than 12 months.

Abstract
Polyoxyethylene lauryl ether (POELE10)-Na2C4H4O6 aqueous two-phase extraction system (ATPES) is a novel and green pretreatment technique to trace samples. ATPES coupled with high-performance liquid chromatography (HPLC) is used to analyze synchronously sulfadiazine (SDZ) and sulfamethazine (SMT) in animal by-products (i.e., egg and milk) and environmental water sample. It was found that the extraction efficiency (E%) and the enrichment factor (F) of SDZ and SMT were influenced by the types of salts, the concentration of salt, the concentration of POELE10 and the temperature. The orthogonal experimental design (OED) was adopted in the multi-factor experiment to determine the optimized conditions. The final optimal condition was as following: the concentration of POELE10 is 0.027gmL(-1), the concentration of Na2C4H4O6 is 0.180gmL(-1) and the temperature is 35°C. This POELE10-Na2C4H4O6 ATPS was applied to separate and enrich SDZ and SMT in real samples (i.e., water, egg and milk) under the optimal conditions, and it was found that the recovery of SDZ and SMT was 96.20-99.52% with RSD of 0.35-3.41%. The limit of detection (LOD) of this method for the SDZ and SMT in spiked samples was 2.52-3.64pgmL(-1), and the limit of quantitation (LOQ) of this method for the SDZ and SMT in spiked samples was 8.41-12.15pgmL(-1).

Abstract
PURPOSE To compare the clinical efficacy of pingyangmycin and lauromacrogol combined with pingyangmycin in the treatment of venous malformations (VMs). METHODS One hundred and twenty patients with VM were randomly divided into lauromacrogol combined with pingyangmycin injection group (experimental group) and pingyangmycin injection group (control group). The appropriate interval between different injection sessions was 2 weeks. After different sessions, the changes of lesions (including size, color, texture) as well as the results of posture test and adverse effects were analyzed by using SPSS11.5 software package. RESULTS According to the international evaluation criteria for VM, the efficacy of the experimental group was significantly better than the control group after 2~5 sessions (P<0.05). However, after 1 and 6 sessions, there was no significant difference in the efficacy between the experimental group and the control group (P>0.05). In addition, the average sessions required in the experimental group were significantly less than those in the control group (P<0.05). CONCLUSIONS Compared to the single use of pingyangmycin, lauromacrogol combined with pingyangmycin is more effective for the treatment of VM, with fewer sessions required and no adverse effects.

Abstract
BACKGROUND Telangiectasias are defined as small venules abnormally dilated, located in the intradermal portion of the skin, of reddish or bluish tinge, their diameter not exceeding 1 mm; they are classified by the American Venous Forum as mild venous disease CEAP C1. Conventional treatment consists of chemical sclerotherapy, considered a minimally invasive technique with rapid clinical recovery. A wide variety of sclerosing solutions can be used for this purpose. METHODS/DESIGN This project intends to include 96 patients that will be randomized to a triple-blind study. Inclusion criteria are women between 18 and 65 years, with telangiectasia on the lateral thigh. Male patients, female patients with chronic venous disease CEAP 2 to 6, women with allergies, pregnant, breastfeeding, with any type of skin problems or any decompensated clinical disease will be excluded. All patients included will be submitted to venous ultrasound mapping in order to rule out venous disease not clinically visible, deep venous system insufficiency, and insufficiency of the ostial valve of the great saphenous vein. One group will be treated with glucose 75% solution and the other will receive polidocanol 0.2% diluted in glucose 70%. Each patient will receive only 1 treatment session in 1 single member. The volume of sclerosing solution will not exceed 5 mL and the treatment area will be limited to a region of 150 cm on the lateral thigh. Clinical follow-up will be: 1 initial visit, when the clinical report will be filled; photographic record and treatment with sclerotherapy (D0); follow-up visits after 7 and 60 days (D7 and D60, respectively), always with clinical and photographic documentation. DISCUSSION The project intends to evaluate the efficacy and safety of sclerotherapy in eliminating telangiectasia in a predetermined area in order to establish efficacy and safety parameters for the treatments presented. CONCLUSION This protocol for clinical trial will provide date to determine the efficacy and safety of sclerotherapy with the solutions presented.

Abstract
OBJECTIVES Head and neck lymphatic malformation is a rare benign tumor, mainly affecting children under 1 year of age. Total resection is often difficult, and recurrence is frequent. Functional and esthetic sequelae are a major issue. MATERIALS AND METHODS A single-center retrospective study recruited patients with head and neck lymphatic malformation managed surgically, with or without associated sclerosis by alcohol, bleomycin or aetoxisclerol, between January 1, 2004 and December 31, 2013. Local control, recurrence and complications rates were analyzed, as were swallowing disorder, tracheostomy and impaired phonation. RESULTS Twenty-three patients, with a mean age of 15.80 years, were included. Location was suprahyoid in 17 cases (73.91%) and infrahyoid in 6 (26.09%). There were 11 macrocysts (47.82%), 2 microcysts (8.70%) and 10 mixed lesions (43.48%). Three patients showed spontaneous resolution; 12 patients (52.17%) underwent a single surgical procedure, 2 (8.7%) multiple procedures, 2 (8.7%) 1 surgical procedure and 1 sclerosis, 2 (8.7%) 1 surgical procedure and multiple scleroses, and 2 (8.7%) multiple procedures and multiple scleroses. The local control rate was 69.56%. There were 8 recurrences (34.78%), all in suprahyoid microcystic or mixed lesions. There were 2 complications (8.7%): 1 severe upper cervical edema following sclerosis of the floor of the mouth, and 1 postsurgical palsy of the marginal mandibular branch of the facial nerve. In 1 case (4.35%), a nasogastric tube was required for 6 days, without tracheostomy. CONCLUSION Recurrence was frequent, with non-negligible functional and esthetic impact, especially in case of suprahyoid and microcystic lesion.

Abstract
Background Our objective was to conduct a pilot study to determine if transcervical administration of polidocanol foam (PF) with or without doxycycline or benzalkonium chloride (BZK) would prevent pregnancy in baboons. Methods In study phase 1, adult cycling baboons underwent a hysterosalpingogram to evaluate tubal patency prior to transcervical infusion of 20 mL of 5% PF followed by 1 mL of saline containing 100 mg doxycycline (5%/doxy; n=5), 3% PF plus doxycycline (3%/doxy; n=4), 3% PF with 0.01% BZK (3%/BZK; n=4) or no additional treatment (control; n=9). Immediately following treatment, animals received intramuscular depot medroxyprogesterone acetate (DMPA, 2 mg/kg) to suppress cyclicity during healing and were then socially housed with males of proven fertility. The primary outcome was pregnancy within six cycles of resumption of menses (efficacy phase 1). During study phase 2, PF-treated females from study phase 1 contributed additional cycles (6–8) of exposure (efficacy phase 2), and 5 control females who had recovered from medical abortion (after study phase 1 pregnancy) were subsequently treated with 5% PF (with DMPA) and exposed to breeding (efficacy phase 1; n=3 six cycles, n=2 five cycles). Results All females resumed normal menstrual cycles and mating activity after DMPA. During efficacy phase 1, 7/9 (78%) control females became pregnant. In contrast, fewer pregnancies occurred in PF-treated females: 5% PF 0/5 (0%), 5%/doxy 1/5 (20%), 3%/doxy 1/4 (25%) and 3%/BZK 1/4 (25%). During efficacy phase 2, only one additional pregnancy occurred (3%/BZK). Conclusions A single transcervical treatment with 5% PF prevented pregnancy in most baboons. Cotreatment with doxycycline or BZK did not improve results. Implications Transcervical intrauterine administration of PF resulted in a high rate of tubal occlusion with prevention of pregnancy; refinements are needed to increase the contraceptive rate following a single treatment to near 100%.

Abstract
Objectives A randomized, placebo-controlled, multicenter study was conducted to evaluate the safety and efficacy of polidocanol endovenous microfoam (1%, Varithena® [polidocanol injectable foam], BTG International Ltd.). Methods Patients (n = 77) with symptomatic, visible varicose veins were randomized to treatment with either Varithena 1% or placebo. Results Varithena provided greater mean changes from Baseline in patient-reported assessments of symptoms (e.g., heaviness, achiness, swelling, throbbing, itching [HASTI®] score 30.7 points vs 16.7 points, p = 0.0009, primary endpoint; and modified Venous Insufficiency Epidemiological and Economic Study-Quality-of-Life/Symptoms [m-VEINES-QOL/Sym; p < 0.001]), physician-assessed VCSS, and physician- and patient-assessed appearance compared with placebo. The HASTI score correlated highly with the modified-VEINES-QOL/Sym and Chronic Venous Insufficiency Questionnaire-2 scores (r = 0.7 to > 0.9, p ≤ 0.001). Adverse events included contusion, incision-site hematoma, and limb discomfort. Venous thrombus adverse events were reported as mild and generally resolved without sequelae. Conclusions Varithena provided significantly greater symptom relief and improvement in leg appearance compared with placebo. Adverse events were generally mild and transient.

Abstract
Surfactant-mediated bioremediation has been widely applied in decontaminating PAH-polluted sites. However, the impacts of surfactants on the biodegradation of PAHs have been controversial in the past years. To gain a clear insight into the influencing mechanisms, three nonionic surfactants (Tween80, TritonX-100 and Brij30) were selected to systematically investigate their effects on cell surface properties (membrane permeability, functional groups and elements), cell vitality as well as subsequent phenanthrene degradation ability of Sphingomonas sp. GY2B. Results showed that biodegradation of phenanthrene was stimulated by Tween80, slightly inhibited by TritonX-100 and severely inhibited by Brij30, respectively. Positive effect of Tween80 may arise from its role as the additional carbon source for GY2B to increase bacterial growth and activity, as demonstrated by the increasing viable cells in Tween80 amended degradation systems determined by flow cytometry. Although TritonX-100 could inhibit bacterial growth and disrupt cell membrane, its adverse impacts on microbial cells were weaker than Brij30, which may result in its weaker inhibitive extent. Results from this study can provide a rational basis on selecting surfactants for enhancing bioremediation of PAHs.
