Chronic lower limb oedema is one of the complications of superficial or deep chronic venous disorders. It is ranked as "C3"on the CEAP classification. In epidemiological studies, the recognition of oedema is mainly based on clinical signs, and oedema is more easily detected in the second part of the day when it becomes evident. We addressed the question whether oedema is already present in the morning in patients suffering of primary varicose veins without trophic changes. In total, 101 patients with primary varicose veins (C2 and/or C3 stage of the CEAP classification) and 122 controls were enrolled as they appeared in our centre. The consultation time was no later than 6 hours after the patient had woken up. Oedema was detected by pitting test and ultrasound. The mean consultation time lapse was 3.7 ± 1.2 hours after waking-up. Oedema was more frequent in the group of primary varicose veins without trophic changes (36 % compared to 14 % in the control group; p < 0.01). Oedema was mainly detected by ultrasound and far less so by the pitting test. Patients with varicose veins have morning oedema more frequently than patients without varicosis and at a higher rate than in epidemiological studies.

Objective: We preoperatively assessed varicose veins by means of computed tomography (CT) with contrast injection in the veins of the lower extremity (CT venography). This paper reports the procedures, results and implications of CT venography from the surgical aspect. Methods: A total of 48 legs in 39 patients were examined. Contrast medium was diluted ten-fold and injected into the lower extremity veins, often using a dual route of injection. The images were reconstructed with the volume-rendering method. Results: CT venography clearly visualized the veins with a small amount of contrast medium and facilitated the identification of anatomy that was not suitable for passing the stripper. In addition, CT venography helped identify unusual types of varicose veins or uncommon sites of inflow of small saphenous veins. Such information was helpful for avoiding unexpected vascular injury or for minimizing skin incision. Dual-route injection was beneficial to minimize the blind zones. Doppler ultrasound could be more focused on hemodynamic assessment and determination of incision sites. Conclusions: CT Venography is feasible in all cases of varicose veins. When performed in conjunction with ultrasonography, it appears to facilitate the safe and efficient treatment of various types of varicose veins. PMID:23555458

Endovascular Radiofrequency Ablation for Varicose Veins

2011-01-01

Executive Summary Objective The objective of the MAS evidence review was to conduct a systematic review of the available evidence on the safety, effectiveness, durability and cost–effectiveness of endovascular radiofrequency ablation (RFA) for the treatment of primary symptomatic varicose veins. Background The Ontario Health Technology Advisory Committee (OHTAC) met on August 26th, 2010 to review the safety, effectiveness, durability, and cost-effectiveness of RFA for the treatment of primary symptomatic varicose veins based on an evidence-based review by the Medical Advisory Secretariat (MAS). Clinical Condition Varicose veins (VV) are tortuous, twisted, or elongated veins. This can be due to existing (inherited) valve dysfunction or decreased vein elasticity (primary venous reflux) or valve damage from prior thrombotic events (secondary venous reflux). The end result is pooling of blood in the veins, increased venous pressure and subsequent vein enlargement. As a result of high venous pressure, branch vessels balloon out leading to varicosities (varicose veins). Symptoms typically affect the lower extremities and include (but are not limited to): aching, swelling, throbbing, night cramps, restless legs, leg fatigue, itching and burning. Left untreated, venous reflux tends to be progressive, often leading to chronic venous insufficiency (CVI). A number of complications are associated with untreated venous reflux: including superficial thrombophlebitis as well as variceal rupture and haemorrhage. CVI often results in chronic skin changes referred to as stasis dermatitis. Stasis dermatitis is comprised of a spectrum of cutaneous abnormalities including edema, hyperpigmentation, eczema, lipodermatosclerosis and stasis ulceration. Ulceration represents the disease end point for severe CVI. CVI is associated with a reduced quality of life particularly in relation to pain, physical function and mobility. In severe cases, VV with ulcers, QOL has been rated to be as bad

Recently, the association of polymorphism rs1800562 (p.C282Y) in the hemochromatosis (HFE) gene with the increased risk of venous ulceration was shown. We hypothesized that HFE gene polymorphism might be involved not only in ulceration process, but also in susceptibility to primary varicose veins. We genotyped HFE p.C282Y (rs1800562) and p.H63D (rs1799945) variants in patients with primary varicose veins (n = 463) and in the control group (n = 754). In our study, p.282Y variant (rs1800562 A allele) was significantly associated with the risk of varicose veins (OR 1.79, 95 % CI = 1.11-2.89, P = 0.02). A borderline significant reverse association of p.63D variant (rs1799945 G allele) with venous leg ulcer development was revealed in Russians (OR 0.25, 95 % CI = 0.06-1.00, P = 0.05), but not in the meta-analysis (P = 0.56). We conclude that the HFE gene polymorphism can affect the risk of developing primary varicose veins.

A study was performed to determine whether the pressures routinely produced by bandaging for compression sclerotherapy of varicose veins are adequate to maintain the superfical veins almost empty of blood. The results suggest that well-applied bandages can provide sufficient support to combat the high distending pressures found in varicose veins. The large variation among different surgeons, however, indicates that any clinical assessment of compression sclerotherapy should include measurement of the pressure at which the bandages are applied.

To assess the effectiveness of adopting endovenous laser treatment (EVLT) as the primary treatment modality for varicose veins at Auckland City Hospital (Auckland, New Zealand). The outcomes of 354 consecutive EVLT procedures performed between 2007 and 2013 were reviewed. Data was collected from a prospectively maintained procedural database and by retrospective chart review. Of the 319 patients who had an ultrasound, at 1 month post-procedure there was a saphenous vein occlusion rate of 96%. Side effects were minimal with no cases of DVT or skin burns and one case of self-limiting neuralgia. The procedure was well tolerated with a median pain score of 3. Since the adoption of EVLT there has been a large increase in the number of patients treated for varicose veins (28 in 2007 compared to 176 in 2013). EVLT is a safe and effective treatment for varicose veins and its adoption has allowed a large increase in the number of varicose vein patients treated at Auckland City Hospital.

Varicose veins (VVs) and varicose ulceration (VU) are usually considered non-life-threatening conditions, but in some cases they can lead to major complications such as fatal bleeding. The aim of this systematic review is to evidence the most updated information on bleeding from VV and VU. As evidence acquisition, we planned to include all the studies dealing with "Haemorrhage/Bleeding" and "VVs/VU". We excluded all the studies, which did not properly fit our research question, and with insufficient data. As evidence synthesis, of the 172 records found, after removing of duplicates, and after records excluded in title and abstract, 85 matched our inclusion criteria. After reading the full-text articles, we decided to exclude 68 articles because of the following reasons: (1) not responding properly to our research questions; (2) insufficient data; the final set included 17 articles. From literature searching, we identify the following main issues to be discussed in the review: epidemiology and predisposing factors, pathophysiology and forensic aspects, first aid. It has been estimated that deaths for bleeding due to peripheral venous problems account up to 0.01% of autopsy cases. From a pathological point of view, venous bleeding may arise from either acute or chronic perforation of an enlarged vein segment through the weakened skin. From a forensic point of view, in cases of fatal haemorrhage the death scene can even simulate non-natural events, due to crime or suicide. In most cases, incorrect first aid led to fatal complications. Further investigation on epidemiology and prevention measures are needed. © 2018 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

To determine the prevalence of haemorrhoids in women with pelvic vein reflux, identify which pelvic veins are associated with haemorrhoids and assess if extent of pelvic vein reflux influences the prevalence of haemorrhoids. Females presenting with leg varicose veins undergo duplex ultrasonography to assess all sources of venous reflux. Those with significant reflux arising from the pelvis are offered transvaginal duplex ultrasound (TVS) to evaluate reflux in the ovarian veins and internal Iliac veins and associated pelvic varices in the adnexa, vulvar/labial veins and haemorrhoids. Patterns and severity of reflux were evaluated. Between January 2010 and December 2012, 419 female patients with leg or vulvar varicose vein patterns arising from the pelvis underwent TVS. Haemorrhoids were identified on TVS via direct tributaries from the internal Iliac veins in 152/419 patients (36.3%) and absent in 267/419 (63.7%). The prevalence of the condition increased with the number of pelvic trunks involved. There is a strong association between haemorrhoids and internal Iliac vein reflux. Untreated reflux may be a cause of subsequent symptomatic haemorrhoids. Treatment with methods proven to work in conditions caused by pelvic vein incompetence, such as pelvic vein embolisation and foam sclerotherapy, could be considered. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

A new varicose vein stripper is described. It is rigid, of small caliber and can be used in both upper and lower limbs. These features make it easy to handle, particularly in young subjects undergoing early stripping. The instrument is less costly than other disposable instruments as it is metallic and can be sterilized.

Varicose vein therapy and nerve lesions.

Hirsch, Tobias

2017-03-01

Treating varicose veins using endovenous thermal techniques - especially laser and radio frequency ablation - has emerged as an effective alternative to open surgery with stripping and high ligation. Even though these methods are very gentle and patient-friendly, they are nevertheless accompanied by risks and side effects. Compared to open surgical therapy, the risk of damage to peripheral and motor nerves is reduced; however, it still exists as a result of heat exposure and tumescent anaesthesia. Non-thermal methods that can be applied without tumescent anaesthesia have been introduced to the market. They pose a considerably lower risk of nerve lesions while proving to be much more effective. This paper investigates data on postoperative nerve damage and paraesthesia using internet research (PubMed). It analyses the current state of knowledge regarding non-thermal treatment methods and takes into account the latest developments in the use of cyanoacrylate to close insufficient saphenous veins.

A prospective, randomised trial was carried out to examine the efficacy of perforate invagination (PIN, Credenhill Ltd, Derbyshire, UK) stripping of the long saphenous vein (LSV) in comparison to conventional stripping (Astratech AB, Sweden) in the surgical management of primary varicose veins. Eighty patients with primary varicosities secondary to sapheno-femoral junction (SFJ) incompetence and LSV reflux were recruited. Patients were randomised to PIN or conventional stripping with all other operative techniques remaining constant. Follow-up was performed at 1 and 6 weeks postoperatively. There were no statistically significant differences between the two techniques in terms of time taken to strip the vein, percentage of vein stripped or the area of bruising at 1 week. The size of the exit site was significantly smaller with the PIN device (P < or = 0.01). Optimal use of the conventional stripper provides results comparable to the PIN device. Choice of stripping device remains the surgeon's, bearing in mind that the PIN stripper achieves slightly better cosmesis. PMID:10364948

One-shot scleroembolization: a new technique for the treatment of varicose veins disease of lower extremities. Preliminary results.

2014-12-01

The aim of this article is to present a new technique for minimally invasive treatment of varicose veins disease of lower extremities. One-shot scleroembolization is a new technique designed for the treatment of varicose veins of the lower extremities, which associates a mechanical interruption of the sapheno-femoral junction to classic sclerotherapy with no need for surgery or anesthesia. This is achieved with the combined use of a coil positioned in the terminal portion of the great saphenous vein and a foamed sclerosant drug. At three months' follow-up no complications have been observed. The great saphenous vein was still occluded in all patients (nine out of nine). One-shot scleroembolization seems to be an effective technique for the treatment of varicose veins disease in outpatients, with the advantage of causing little distress to the patient. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Varicose veins are common and can impact patients' quality of life, but consensus regarding the evaluation of varicose vein symptoms is lacking and existing measures have limitations. This research aimed to develop and establish the content validity of a new electronic patient-reported outcome (PRO) measure, the VVSymQ ® instrument, to assess symptoms of superficial venous insufficiency (varicose veins) in clinical trials. The development of the VVSymQ ® instrument began with qualitative interviews with patients based on the symptom domain of the VEINES-QOL/Sym, an existing PRO instrument for chronic venous disorders of the leg. Three phases of qualitative research were conducted to examine the relevance and importance of the symptoms to patients with varicose veins, and the patients' ability to understand and use the VVSymQ ® instrument. The development included evaluating questions that had 1-week and 24-h recall periods, and paper and electronic versions of the new instrument. Five symptoms (heaviness, achiness, swelling, throbbing, and itching [HASTI™]) were consistently reported by patients across all sources of qualitative data. The final version of the VVSymQ ® instrument queries patients on the HASTI™ symptoms using a 24-h recall period and a 6-point duration-based response scale ranging from "None of the time" to "All of the time," and is administered daily via an electronic diary. Cognitive interviews demonstrated varicose vein patients' understanding of and their ability to use the final version of the VVSymQ ® instrument. Content validity was established for the VVSymQ ® instrument, which assesses the five HASTI™ symptoms of varicose veins daily via an electronic diary and has promise for use in research and practice.

Objective(s): We intended to determine whether the ovarian varicose which is one of the common etiologies of the pelvic congestion syndrome, has the ability to interfere with the DNA methylation reprogramming in the oocyte and thereby affect the oocyte quality or not. Materials and Methods: Varicose model was induced according to the Turner’s method in the rats. Briefly, a 20-gauge needle was placed on the left renal vein and a thread was tied over both the needle and the renal vein medial to the insertion of the ovarian vein, and then the needle was removed. Evaluation of prooxidant-antioxidant balance (PAB) was assessed using specific kits and the expression level of the DNA methyltransferase genes Dnmt1, Dnmt3a and Dnmt3L was assessed by Real-time PCR. Immunofluorescent staining for 5-methylcytosine in the oocytes evaluated the global DNA methylation. Results: A significant PAB increase in the ovaries from varicose group was seen. Real-time PCR demonstrated a remarkable decrease in the expression of the Dnmt3a and Dnmt3L which are responsible for de novo DNA methylation in the oocytes. Immunofluorescent staining for 5-mC showed a reduction in the fluorescence intensity in the oocytes collected from the varicose group. Conclusion: Our findings from Real-time PCR and immunocytochemistry suggest that the epigenetic parameters in the oocyte could be affected by varicose induction and these epigenetic alteration has the potential to affect the oocyte quality. We suggest that the epigenetic changes could happen in the oocytes after the induction of ovarian varicose and lead to the oocyte quality reduction or even infertility. PMID:29147493

Objective. To evaluate the effectiveness of surgery in treating primary varicose veins in the lower limbs by photoplethysmography (PPG) and duplex mapping (DM). Method. Forty-eight lower limbs were clinically evaluated according to the CEAP classification system and subjected to PPG and DM exams. Each limb had a venous refill time (VRT) of <20 seconds and a normal deep vein system (DVS) by DM. Results. The mean pre- and postoperative VRTs were 13.79 and 26.43 seconds, respectively (P < 0.0001). After surgery, 42 limbs (87.50%) had normal results by PPG (VRT > 20 seconds). Four limbs (8.33%) showed improved VRTs, but the VRTs did not reach 20 seconds. In the 2 limbs (4.17%) that maintained their original VRTs, the DM exams showed the presence of insufficient perforating veins. Conclusion. In most cases, PPG allows for a satisfactory evaluation of the outcome of varicose vein surgery. PMID:24696783

To analyze Internet search data to characterize the temporal and geographic interest of Internet users in the United States in varicose vein treatment. From January 1, 2004, to September 1, 2012, the Google Trends tool was used to analyze query data for "varicose vein treatment" to identify individuals seeking treatment information for varicose veins. The term "varicose vein treatment" returned a search volume index (SVI), representing the search frequency relative to the total search volume during a specific time interval and region. Linear regression analysis and Kruskal-Wallis one-way analysis of variance were employed to characterize search results. Search traffic for varicose vein treatment increased by 520% over the 104-month study period. There was an annual mean increase of 28% (range, -18%-100%; standard deviation [SD], 35%), with a statistically significant linear increase in average yearly SVI over time (R(2) = 0.94, P < .0001). All years showed positive growth in mean SVI except for 2008 (18% decrease). There were statistically significant differences in SVI by month (Kruskal-Wallis, P < .0001) with significantly higher mean SVI compared with other months in May (190% increase; range, 26%-670%; SD, 15%) and June (209% increase; range, 35%-700%; SD, 20%). The southern United States showed significantly higher search traffic than all other regions (Tukey-Kramer, P < .00001). There have been significant increases in Internet search traffic related to varicose vein treatment in the past 8 years. Reflected in this trend is an annual peak in search traffic in the late spring months with an overall geographic bias toward southern states. Rigorous analysis of Internet search queries for medical procedures may prove useful to guide the efficient use of limited resources and marketing dollars. © 2013 The Society of Interventional Radiology Published by SIR All rights reserved.

To analyze serum biomarkers of CVD in selected patients with primary axial reflux of great saphenous vein in one or both lower limbs. Ninety-six patients affected by uncomplicated varicose veins, were enrolled in the study. A unilateral, primary axial reflux in great saphenous veins was detected in 54 patients (U-CVD group) and a bilateral one in 42 (B-CVD group). Sixty-five age and sex-matched subjects without venous reflux were enrolled as controls. Mean venous pressure of both lower limbs at the distal great saphenous vein (mGSVP) and venous reflux were measured by continuous-wave Doppler ultrasound and echoduplex scanning, respectively. Reactive Oxygen Species (ROS), tissue Plasminogen Activator (t-PA) and its Inhibitor 1 (PAI-1) activities, Hematocrit (HTC), White Blood Cells (WBC), Neutrophyls (NEU), Platelets (PLT), Fibrinogen (FIB) and Blood Viscosity (BV) were assessed in blood samples drawn from the antecubital vein. B-CVD group showed higher fibrinogen values (p < 0.005) and higher mean venous pressure (0 < 0.0001) in comparison to controls, while U-CVD did not. No difference was found between both groups and controls for all the other parameters. Increased fibrinogen levels in patients with bilateral varicose veins may represent an early warning signal, as it could be associated to the long-term progression of chronic venous disease.

A 40-year-old woman with a history of alopecia areata related to stress or hormonal changes was treated for bilateral primary symptomatic varicose veins (CEAP clinical score C2S) of pelvic origin, using a staged procedure. Her first procedure entailed pelvic vein embolisation of three pelvic veins using 14 coils and including foam sclerotherapy of the tributaries, using 3% sodium tetradecyl sulphate. Following this procedure, she had an exacerbation of alopecia areata with some moderate shedding of hair. Subsequently, she underwent endovenous laser ablation under local anaesthetic without incident. Seven months after the pelvic vein embolisation, she underwent foam sclerotherapy of leg and labial varicose veins using sodium tetradecyl sulphate. Two days following this procedure, she had a severe exacerbation of alopecia areata with gross shedding of hair. These two episodes of exacerbation of alopecia areata appear to be associated with sodium tetradecyl sulphate foam sclerotherapy of veins.

Ultrasound-guided foam sclerotherapy and endovenous laser ablation are widely used alternatives to surgery for the treatment of varicose veins, but their comparative effectiveness and safety remain uncertain. In a randomized trial involving 798 participants with primary varicose veins at 11 centers in the United Kingdom, we compared the outcomes of foam, laser, and surgical treatments. Primary outcomes at 6 months were disease-specific quality of life and generic quality of life, as measured on several scales. Secondary outcomes included complications and measures of clinical success. After adjustment for baseline scores and other covariates, the mean disease-specific quality of life was slightly worse after treatment with foam than after surgery (P=0.006) but was similar in the laser and surgery groups. There were no significant differences between the surgery group and the foam or the laser group in measures of generic quality of life. The frequency of procedural complications was similar in the foam group (6%) and the surgery group (7%) but was lower in the laser group (1%) than in the surgery group (P<0.001); the frequency of serious adverse events (approximately 3%) was similar among the groups. Measures of clinical success were similar among the groups, but successful ablation of the main trunks of the saphenous vein was less common in the foam group than in the surgery group (P<0.001). Quality-of-life measures were generally similar among the study groups, with the exception of a slightly worse disease-specific quality of life in the foam group than in the surgery group. All treatments had similar clinical efficacy, but complications were less frequent after laser treatment and ablation rates were lower after foam treatment.

To investigate which factors other than history of superficial vein thrombosis (SVT) are associated with recurrent spontaneous SVT episodes in patients with varicose veins (VVs). Patients with a history of spontaneous SVT and VVs were followed up for a mean period of 55 months. Demographics, comorbidities, and thrombophilia screening test were analyzed. Patients were grouped according to the clinical-etiology-anatomy-pathophysiology classification. A multiple logistic regression analysis with the forward likelihood ratio method was undertaken. Thirteen patients out of 97 had a recurrence SVT episode during the follow-up period. All those patients were identified to have a thrombophilia defect. Protein C and S, antithrombin, and plasminogen deficiencies were more frequently present in patients without recurrence. Gene mutations were present in 38% in the nonrecurrence group and 77% in the recurrence group. After logistic regression analysis, patients with dislipidemia and mutation in prothrombin G20210A (FII) had an increased risk for recurrence by 5.4-fold and 4.6-fold, respectively. No deep vein thrombosis or pulmonary embolism occurred. Dislipidemia and gene mutations of F II are associated with SVT recurrence in patients with VVs. A selection of patients may benefit from anticoagulation in the short term and from VVs intervention in the long term. © The Author(s) 2015.

Whereas chronic venous insufficiency and varicose veins (VVs) are a universally recognized problem, they are frequently underappreciated as major contributors to long-term morbidity in the elderly despite the increasing prevalence with age. Previous studies have demonstrated that chronic venous insufficiency and VV treatments in patients ≥65 years old yield an overall benefit; however, there have been few data as to whether octogenarians are undergoing these procedures and with what success. As such, our objectives were to investigate the procedures selected, to examine clinical outcomes after VV procedures in elderly patients ≥80 years old, and to explore complication rates (both systemic and leg specific) after VV procedures in patients ≥80 years old. We performed a retrospective review using the Vascular Quality Initiative Varicose Vein Registry of all VV procedures performed for ≥C2 disease from January 2015 to February 2017. We divided all procedures into three age groups: patients <65 years, patients ≥65 to 79 years, and patients ≥80 years. Statistical testing included χ 2 test for categorical variables and Student t-test for continuous variables. Two comparisons were performed: first, comparing patients <65 years old with patients ≥65 to 79 years old; and second, comparing patients ≥65 to 79 years old with patients ≥80 years old. There were a total of 12,262 procedures performed, with 8608 procedures in the patients <65 years, 3226 in patients 65 to 79 years, and 428 procedures in patients ≥80 years. A total of 22,050 veins were treated during the 12,262 procedures. Almost half of procedures (46.51%; n = 5703) had only one vein treated during a single procedure. Between age groups, the percentage of one vein treated increased as the patient's age increased, ranging from 45.39% (n = 3875) for patients <65 years to 48.55% (n = 1555) for patients between 65 and 79 years and 64.08% (n = 273) for patients ≥80�

The aim of study was to evaluate the effectiveness of surgical "barrier techniques" in prevention of phenomenon of inguinal neovascularization in patients with varicose veins of lower limbs. There were 68 patients (80 limbs) treated with flush ligation of saphenofemoral junction, stripping of great saphenous vein and avulsion of varicosities. Patients were divided in three groups: I (no "barrier techniques")--40 limbs; II (anatomical barrier)--20 limbs and III (synthetic barrier)--20 limbs. Duplex ultrasound was performed at interval of 24 months postoperatively. Signs of neovascularization were found more frequently in group I--22.5% of limbs vs 7.5% of limbs in patients with utilization of "barrier techniques". There were types B1, B2a and B2b of neovascularization only, according to Fischer classification. We conclude that use of a "barrier techniques", either anatomic or synthetic, is associated with a decreased incidence of neovascularization at the level of the saphenofemoral junction compared with a control group.

To assess venous hemodynamics and quality of life at lest five years after varicose vein stripping. We conducted a prospective study with 39 patients (63 limbs) with primary lower limbs varicose veins. Preoperatively, all patients were subjected to clinical evaluation, duplex ultrassound, air plethysmography (APG), and CIVIQ questionnaire of quality of life. By APG, venous filling index (VFI), ejection fraction (EF), and residual volume fraction (RVF) were determined. CIVIQ addresses four domains in course of 20 questions, including states of physical, social, and psychological well-being, and pain level. Varicose veins were treated by standard venous stripping. At least five years after surgery (77.9 ± 10.9 months), patients were reassessed and had clinical examination, duplex ultrasound, APG, and CIVIQ repeated. No late follow-up data was available for 24 patients. Preoperative and late postoperative VFI levels were similar, whereas EF (P=0.05) and RVF (P=0.01), as hemodynamic variables, significantly improved following surgery. In the late postoperative period, overall CIVIQ scores were significantly lower (P=0.005), as were scores in all four domains: pain (P=0.001), physical (P=0.007), social (P=0.008), and psychological (P= 0.05). In a small prospective cohort, improvements in venous hemodynamics and in quality of life of patients submitted to standard varicose veins stripping were maintained five years after the procedure.

The aim of this study was to evaluate the ability of ultrasound (US) to measure the parietal thickness of varicose veins. In a blind in vitro analysis, 28 great saphenous veins, obtained after stripping surgery from 28 patients with chronic venous insufficiency, were examined with a digital US scanner ATL-HDI5000, linear 5-1 to 2-MHz broadband probe, compound imaging technique and analogic-digital zooming. We obtained one to three progressive measurements for each vein wall (total 67 parietal thicknesses). The samples, fixed in formalin, were sent to the pathology laboratory: sections were obtained at the same level of the sonographic planes, and images were obtained by digital camera mounted on an optical microscope. Measurements obtained at histology were considered as the gold standard. K-statistic was applied to compare sonographic and histologic measurements. Considering only the hypoechoic wall portion, 29/29 (100%) diagnoses of hypotrophy (K=0.91), 19/22 (86%) diagnoses of normotrophy (K=0,47) and 12/16 (75%) diagnoses of hypertrophy (K=0.7) were obtained by sonography. In our preliminary experience, the in vitro study of varicose veins allows precise, at least morphological, detection of hypotrophic walls. If these preliminary data are confirmed in vivo, sonography could be used to discriminate patients eligible for conservative treatment instead of surgery.

Cerebrovascular events have been noted after foam sclerotherapy for varicose veins. One hypothesis is migration of microemboli to the brain through a cardiac septal defect. The aim of this study was to identify whether acoustic reflectors are found in the right side of the heart during radiofrequency ablation of varicose veins, as neurological events are not reported during these procedures. Transthoracic echocardiography was performed during local anaesthetic radiofrequency ablation (VNUS ClosureFast) of the great saphenous vein in 14 patients. An apical view was captured at the start of the procedure, during each cycle of heating and at 1 min post-treatment. Patients were monitored for 1 h. Video loops were read by an independent cardiologist. The presence of acoustic reflectors was classified as: 0 = absent, 1 = occasional, 2 = stream, 3 = complete opacification. Loops were of diagnostic quality in 11/14 (79%) patients. After the second cycle of heating, acoustic reflectors moving through the right heart were seen in 5/11 (45%) patients. These were classified as grade 1 in four patients and grade 2 in one patient. No acoustic reflectors were seen in the left heart. No neurological symptoms were reported. Acoustic reflectors in the right heart are a common finding during radiofrequency ablation of varicose veins. Considering the prevalence of cardiac septal defects (17%), more neurological events would be expected if these particles were indeed responsible for these events. Further work is required to elicit the mechanisms underlying neurological complications following sclerotherapy. © The Author(s) 2014.

Endovenous Laser Ablation (EVLA) is one of the most accepted treatment options for varicose veins. The aim of this study was to investigate the efficacy and safety of the new radial fiber slim (ELVeS-radial-slim kit™) for the 1470 nm diode laser in perforator veins with a 1 month follow-up. Our prospective observational cohort study comprised 69 perforating veins in 55 patients. Ninety percent of all patients were in the CEAP-stage C3-C6. The radial fiber slim was used to occlude the perforating vein and the great or small saphenous vein in the same procedure. The primary efficacy endpoint of the study was ultrasonographically proven elimination of venous reflux in the perforating vein after at least one month. Secondary efficacy and further safety end points after one month were as follows: (1) sonographic exclusion of recanalization of the treated vein segments, (2) deep vein thrombosis (DVT), clinical pulmonary embolism (PE), or superficial vein thrombosis (SVT) as defined by objective testing, (3) death from any cause, (4) persistent clinical complaints such as pain and paresthesia. Follow-up could be completed in all patients. In all treated perforating varicose veins, occlusion with elimination of reflux could be demonstrated immediately after the procedure. After one month 95.6% of the treated veins were still occluded (67/69). During follow-up, we did not diagnose any DVT, PE or SVT in the area related to the treated perforating vein. No patient died. One patient reported paresthesia distally of the puncture site. Endovenous laser treatment of varicose perforating veins with 1470 nm diode laser using the radial fiber slim is effective and safe with low recanalization rates during 1-month follow-up.

Mathematical Modeling of Radiofrequency Ablation for Varicose Veins

We present a three-dimensional mathematical model for the study of radiofrequency ablation (RFA) with blood flow for varicose vein. The model designed to analyze temperature distribution heated by radiofrequency energy and cooled by blood flow includes a cylindrically symmetric blood vessel with a homogeneous vein wall. The simulated blood velocity conditions are U = 0, 1, 2.5, 5, 10, 20, and 40 mm/s. The lower the blood velocity, the higher the temperature in the vein wall and the greater the tissue damage. The region that is influenced by temperature in the case of the stagnant flow occupies approximately 28.5% of the whole geometry, while the region that is influenced by temperature in the case of continuously moving electrode against the flow direction is about 50%. The generated RF energy induces a temperature rise of the blood in the lumen and leads to an occlusion of the blood vessel. The result of the study demonstrated that higher blood velocity led to smaller thermal region and lower ablation efficiency. Since the peak temperature along the venous wall depends on the blood velocity and pullback velocity, the temperature distribution in the model influences ablation efficiency. The vein wall absorbs more energy in the low pullback velocity than in the high one. PMID:25587351

The aim of the study was to assess the suitability of radiofrequency ablation (RFA), endovenous laser ablation (EVLA), and foam sclerotherapy (FS) for patients with symptomatic varicose veins (VVs). The study comprised 403 consecutive patients with symptomatic VVs. Data on 577 legs from 403 consecutive patients with symptomatic VVs were collected for the year 2006. Median patient age was 55 years (interquartile range 45-66), and 62% patients were women. A set of criteria based on duplex ultrasonography was used to select patients for each procedure. Great saphenous vein (GSV) reflux was present in 77% (446 of 577) of legs. Overall,more » 328 (73%) of the legs were suitable for at least one of the endovenous options. Of the 114 legs with recurrent GSV reflux disease, 83 (73%) were suitable to receive endovenous therapy. Patients with increasing age were less likely to be suitable for endovenous therapy (P = 0.03). Seventy-three percent of patients with VVs caused by GSV incompetence are suitable for endovenous therapy.« less

Objective Mechanochemical ablation is a novel technique for ablation of varicose veins utilising a rotating catheter and liquid sclerosant. Mechanochemical ablation and radiofrequency ablation have no reported neurological side-effect but the rotating mechanism of mechanochemical ablation may produce microbubbles. Air emboli have been implicated as a cause of cerebrovascular events during ultrasound-guided foam sclerotherapy and microbubbles in the heart during ultrasound-guided foam sclerotherapy have been demonstrated. This study investigated the presence of microbubbles in the right heart during varicose vein ablation by mechanochemical abaltion and radiofrequency abaltion. Methods Patients undergoing great saphenous vein ablation by mechanochemical abaltion or radiofrequency ablation were recruited. During the ablative procedure, the presence of microbubbles was assessed using transthoracic echocardiogram. Offline blinded image quantification was performed using International Consensus Criteria grading guidelines. Results From 32 recruited patients, 28 data sets were analysed. Eleven underwent mechanochemical abaltion and 17 underwent radiofrequency abaltion. There were no neurological complications. In total, 39% (11/28) of patients had grade 1 or 2 microbubbles detected. Thirty-six percent (4/11) of mechanochemical abaltion patients and 29% (5/17) of radiofrequency ablation patients had microbubbles with no significant difference between the groups ( p=0.8065). Conclusion A comparable prevalence of microbubbles between mechanochemical abaltion and radiofrequency ablation both of which are lower than that previously reported for ultrasound-guided foam sclerotherapy suggests that mechanochemical abaltion may not confer the same risk of neurological events as ultrasound-guided foam sclerotherapy for treatment of varicose veins.

Biological findings from the PheWAS catalog: focus on connective tissue-related disorders (pelvic floor dysfunction, abdominal hernia, varicose veins and hemorrhoids).

Pelvic floor dysfunction, specifically genital prolapse (GP) and stress urinary inconsistency (SUI) presumably co-occur with other connective tissue disorders such as hernia, hemorrhoids, and varicose veins. Observations on non-random coexistence of these disorders have never been summarized in a meta-analysis. The performed meta-analysis demonstrated that varicose veins and hernia are associated with GP. Disease connections on the molecular level may be partially based on shared genetic susceptibility. A unique opportunity to estimate shared genetic susceptibility to disorders is provided by a PheWAS (phenome-wide association study) designed to utilize GWAS data concurrently to many phenotypes. We searched the PheWAS Catalog, which includes the results of the PheWAS study with P value < 0.05, for genes associated with GP, SUI, abdominal hernia, varicose veins and hemorrhoids. We found pronounced signals for the associations of the SLC2A9 gene with SUI (P = 6.0e-05) and the MYH9 gene with varicose veins of lower extremity (P = 0.0001) and hemorrhoids (P = 0.0007). The comparison of the PheWAS Catalog and the NHGRI Catalog data revealed enrichment of genes associated with bone mineral density in GP and with activated partial thromboplastin time in varicose veins of lower extremity. In cross-phenotype associations, genes responsible for peripheral nerve functions seem to predominate. This study not only established novel biologically plausible associations that may warrant further studies but also exemplified an effective use of the PheWAS Catalog data.

Previous studies have demonstrated improvement of venous hemodynamics after surgical treatment of primary varicose veins of the lower extremities using air plethysmography (APG). To correlate the venous hemodynamics obtained by APG with the CEAP classification after surgical treatment of primary varicose veins. We studied 63 limbs of 39 patients (35 women and 4 men) aged on average 46.3 years, operated upon at the University Hospital, Faculty of Medicine of Ribeirão Preto, University of São Paulo, during the period from January 2001 to December 2004. The 63 limbs were divided into the three following groups according to CEAP classification: group C2 + C3 (38 limbs), group C4 (15 limbs) and group C5 + C6 (10 limbs). The patients were evaluated clinically before and 30 to 40 days after surgery by preoperative duplex ultrasonography and pre- and postoperative APG. There was an apparent hemodynamic improvement after surgical treatment of the varicose veins in the two groups of lower severity, but the improvement was significant in the most severe group based on venous filling index. Surgical treatment was beneficial for all three groups, but the greatest hemodynamic gain was observed in the group of highest clinical severity (group C5 + C6).

Most applications of gradual pressure-decline compressing stockings (GPDCS) are used in the United States and Western European countries, with over a decade of clinical experiments. Up to know, there is no standard establishment of gradual pressure-decline compressing stockings for Asian patients with venous insufficiency and varicose vein formations. We collected data on volunteer candidates of varicose vein for general measurements and assessments and magnetic resonance imaging (MRI) by non-contrast enhanced MRV techniques, and for post processing data analysis. Clinical use of GPCDS provide a mild to moderate improvement in the varicose vein conditions of patients with deep venous insufficiency by improving their deep vein circulation, by general measurements; recording major symptoms and complaint; comfort and stretching/flexibility to the candidates after using GPDCS; and area changes/flow velocity changes/available hemoglobin changes in deep veins monitored by MRI. The benefits and data collected in these results may help in developing compression stockings standards in Taiwanese and Asian countries, and to establishing criterias for product sizes, compression levels, and related parameters.

The purpose of this paper was to describe patterns of superficial reflux in the groin with respect to the terminal valve (TV), which is located at the saphenous opening to the common femoral vein, the great saphenous vein, and its tributary veins. This study included 2019 legs with chronic venous insufficiency that received endoluminal varicose vein treatment because of varicosities with insufficiency of the saphenofemoral junction (SFJ). In a preoperative duplex ultrasound investigation of the superficial vein system, reflux after provocation in the SFJ, great saphenous vein, cranial veins (superficial external pudendal vein, superficial epigastric vein, superficial circumflex iliac vein), and anterior and posterior accessory saphenous veins was recorded and classified on the basis of the origin of reflux. In 1348 legs (66.8%), the reflux had its origin exclusively in the common femoral vein. In 170 legs (8.4%), the reflux had its origin in the common femoral and cranial veins. In 430 legs (21.3%), the insufficiency was due to saphenocranial reflux only. In 71 legs (3.5%), the origin of reflux could not be determined. Reflux in the SFJ does not involve the TV in 24.8% of the legs, implying that routine high ligation and ablation close to the TV might be overtreatment in these patients.

The purpose of the study was to analyze a systemic activation of hemostasis and concentration of matrix metalloproteinase 10 (MMP-10) in patients with primary varicose veins (PVVs). A study group consisted of 41 patients with noncomplicated PVVs. A control group consisted of 30 age- and sex-matched healthy individuals without varicose veins. The concentration of d-dimers (DD), prothrombin fragments 1 and 2 (F1+2), antigen of von Willebrand factor (vWF), and activity of plasminogen activator inhibitor (PAI-1) in plasma and concentration of MMP-10 in serum were analyzed. In patients with PVVs, higher concentrations of DD (P < .001), F1+2 (P < .001), vWF (P = .027), MMP-10 (P = .006), and higher activity of PAI-1 (P < .001) were observed. However, no correlation between the concentrations of MMP-10 and prothrombotic markers was found. Noncomplicated PVVs are associated with systemic, prothrombotic activation of hemostasis and increased concentration of MMP-10, suggesting a prothrombotic and proinflammatory state. © The Author(s) 2014.

The cellular mechanisms of primary varicose great saphenous veins (GSVs) involve inflammation, apoptosis, and proliferation of local cells and extracellular matrix degradation. Long non-coding RNAs (lncRNAs) play important roles in these cellular processes; however, which and how lncRNAs related to these mechanisms take effect on GSVs remain unclear. By screening lncRNAs that might experience changes in GSV varicosities, we selected the lower expressed lncRNA-GAS5 (growth arrest specific transcript 5) for functional assessments. Silencing of lncRNA-GAS5 promoted cell proliferation and migration, and cell cycle of the human saphenous vein smooth muscle cells (HSVSMCs), whereas overexpressing it inhibited these cellular behaviors and reduced apoptosis of HSVSMCs. RNA pull-down experiment revealed a direct bind of lncRNA-GAS5 to a Ca2+-dependent RNA-binding protein, Annexin A2. Further experiments showed that silencing of Annexin A2 reduced the HSVSMCs proliferation and vice versa. In the context of lncRNA-GAS5 knockdown, silencing of Annexin A2 reduced the proliferation of HSVSMCs while overexpression of Annexin A2 increased the proliferation. Thus, the low expression of lncRNA-GAS5 may facilitate HSVSMCs proliferation and migration through Annexin A2 and thereby the pathogenesis of GSV varicosities. PMID:25806802

In the intersaphenous vein (ISV) there may take place the so-called "antegrade" or "paradoxical" reflux. This type of blood flow is revealed in a series of patients during muscular diastole and is a link of the pathogenesis of varicose disease, but has, as distinct from the "classical" reflux, an antegrade direction. An incompetent saphenopopliteal junction (SPJ) is a source of the antegrade diastolic blood flow (ADBF) through the ISV. Descriptions of possible variants of impaired blood flow through the ISV are fragmentary and their interpretations are controversial. Prevalence and pathogenesis of these disorders impairments have not yet been studied. A cross-sectional study: over 4 years three centres examined a total of 1,413 patients diagnosed with class C2-C6 varicose veins according the CEAP classification. All patients underwent ultrasound duplex scanning of lower limb veins. The ADBF was determined as a unidirectional antegrade blood flow with the duration of not more than 0.5 second, observed after the crus was relived of compression (in the diastole). Of the patients included into the study who had no varicose veins on the contralateral extremity with the ISV being spotted we sequentially selected 40 subjects including them into the Study Group for the analysis of blood flow and the diameter of the ISV in health. Impairments of blood flow in the ISV were revealed in 61 (4.8%) of 1,265 extremities included into the study: the "classical" reflux in 9 (14.8%) limbs, ADBF was revealed in 37 (60.7%) limbs, a combination of the "classical" blood flow and ADBF - in 15 (24.6%) limbs. Hence, the patients were subdivided into three groups. Studying the nature of blood flow through the ISV in the control group on 40 lower limbs revealed no blood flow disorders. The mean ISV diameter amounted to 1.68 mm (ME=1 mm). The ISV diameter was considerably higher in all studied groups as compared with the control one (p<0.0001). The diameter of the ISV in its proximal portion

[Purpose] The aim of this study was to investigate the effects of sequential pneumatic compression therapy on venous blood flow, refilling time, pain level, and quality of life in women with varicose veins. [Subjects and Methods] Twenty-eight females with varicose veins were selected and randomly allocated to a control group, and experimental group. Maximum and mean venous blood velocities, the refilling time, pain by visual analog scale and quality of life by Aberdeen Varicose Veins Questionnaire were measured in all patients before and after six weeks of treatment. Both groups received lower extremity exercises; in addition, patients in the experimental group received sequential pneumatic compression therapy for 30 minutes daily, five days a week for six weeks. [Results] All measured parameters improved significantly in both groups, comparison of post treatment measurements between groups showed that the maximum and mean blood flow velocity, the pain level, and quality of life were significantly higher in the experimental group compared with the control group. On the other hand there was no significant difference between groups for refilling time. [Conclusion] Sequential pneumatic compression therapy with the applied parameters was an effective modality for increasing venous blood flow, reducing pain, and improving quality of women life with varicose veins.

Common discomforts of pregnancy experienced in the lower extremity include sciatica, leg cramps and varicose veins. Whilst research attention has focused on aetiology and outcomes, the health service utilisation of pregnant women suffering from these complaints has been largely overlooked. To examine the health status and health service utilisation profile of pregnant women experiencing sciatica, leg cramps or varicose veins. Linear and logistic regression was applied to a cross-sectional survey of a pregnant women drawn from the 1973 to 1978 cohort (aged 31-36 years in 2009), of the Australian Longitudinal Study on Women's Health (n=1835). Participant's demographics, health status and health service utilisation were compared for all three complaints based upon three subgroups (yes, sought help; yes, did not seek help; no). A number of women experienced sciatica (22.1%), leg cramps (18.2%) or varicose veins (9.4%). Of these, a greater proportion of women with sciatica (79.3%) or varicose veins (71.5%) sought help for their condition compared with women with leg cramps (46.7%). Comparisons between women with the conditions of interest who did seek help and those who did not only found that women with a university degree were 0.29 (95% CI: 0.10, 0.85) times less likely to seek help for their condition compared to women with a school only education. Further research examining all health seeking behaviour and treatment use of pregnant women who experience lower extremity problems is required in order to facilitate safe, effective and coordinated maternity care to further support these women during pregnancy.

Although varicose veins are a common cause of morbidity, the UK National Health Service and private medical insurers have previously sought to ration their treatment in a non-evidence based manner in order to limit health-care expenditure and reimbursement. In July 2013, the UK National Institute for Health and Care Excellence published new national Clinical Guidelines (CG168) to promote evidence-based commissioning and management of varicose veins. The aim of this study was to evaluate the impact of CG168 on the referral and management of varicose veins at the Heart of England NHS Foundation Trust, Birmingham, UK. Interrogation of a prospectively gathered database, provided by the Heart of England NHS Foundation Trust Performance Unit, of patients undergoing interventions for varicose veins since 1 January 2012. Patients treated before (group 1) and after (group 2) publication of CG168 were compared. There were 253 patients, 286 legs (48% male, mean (range) age 54 (20-91) years) treated in group 1, and 417 patients, 452 legs, (46% male, mean (range) age 54 (14-90) years) treated in group 2, an increase of 65%. CG168 was associated with a significant reduction in the use of surgery (131 patients (52%) group 1 vs. 127 patients (30%) group 2, p = 0.0003, χ(2)), no change in endothermal ablation (30 patients (12%) group 1 vs. 45 patients (11%) group 2), a significant increase in ultrasound-guided foam sclerotherapy (92 patients (36%) group 1 and 245 patients (59%) group 2, p = 0.0001, χ(2)) and an increase in treatment for C2/3 disease (53% group 1 and 65.2% group 2, p = 0.0022, χ(2)). Publication of National Institute for Health and Care Excellence CG168 has been associated with a significant increase (65%) in the number of patients treated, referral at an earlier (CEAP C) stage and increased use of endovenous treatment. CG 168 has been highly effective in improving access to, and quality of care, for varicose veins at Heart of England NHS Foundation

Long saphenous vein (LSV) stripping is the most common surgical procedure in patients affected by varicose disease of the lower limbs. Reactive oxygen metabolites (ROM) generation plays a crucial role in chronic venous insufficiency (CVI). The aim of this study was to investigate whether ROM generation is increased in patients affected by varicose disease versus healthy controls and whether LSV stripping has a positive effect on the local production of ROM. The local production of ROM was assessed measuring hydroperoxides in the blood collected from the leg of 30 patients consecutively undergoing LSV stripping and 30 controls. In both the patient group and the control group, the test was repeated 30 days later. We found that ROM levels before surgery are higher in varicose vein patients than in controls ( p <.0001) and that ROM are significantly reduced 30 days after LSV stripping ( p <.0001). At that time point, no significant differences between patients and controls was found. We also found that sex and age do not affect ROM concentration in patients and controls, either before or after surgery. In conclusion, our data indicate that CVI is characterized by significant oxidative stress and that LSV stripping is able to normalize local production of ROM in patients with varicose disease of the lower limbs. We suggest that measurement of ROM might be useful to test the positive effects of LSV stripping in these patients.

The objective of this paper is to introduce the schematic protocol of radiofrequency (RF) ablation for the treatment of varicose veins. Indication: anatomic or pathophysiologic indication includes venous diameter within 2–20 mm, reflux time ≥0.5 seconds and distance from the skin ≥5 mm or subfascial location. Access: it is recommended to access at or above the knee joint for great saphenous vein and above the mid-calf for small saphenous vein. Catheter placement: the catheter tip should be placed 2.0 cm inferior to the saphenofemoral or saphenopopliteal junction. Endovenous heat-induced thrombosis ≥class III should be treated with low-molecular weight heparin. Tumescent solution: the composition of solution can be variable (e.g., 2% lidocaine 20 mL+500 mL normal saline+bicarbonate 2.5 mL with/without epinephrine). Infiltration can be done from each direction. Ablation: two cycles’ ablation for the first proximal segment of saphenous vein and the segment with the incompetent perforators is recommended. The other segments should be ablated one time. During RF energy delivery, it is recommended to apply external compression. Concomitant procedure: It is recommended to do simultaneously ambulatory phlebectomy. For sclerotherapy, it is recommended to defer at least 2 weeks. Post-procedural management: post-procedural ambulation is encouraged to reduce the thrombotic complications. Compression stocking should be applied for at least 7 days. Minor daily activity is not limited, but strenuous activities should be avoided for 2 weeks. It is suggested to take showers after 24 hours and tub baths, swimming, or soaking in water after 2 weeks.

Endovascular Laser Therapy for Varicose Veins

PubMed Central

2010-01-01

Executive Summary Objective The objective of the MAS evidence review was to conduct a systematic review of the available evidence on the safety, effectiveness, durability and cost–effectiveness of endovascular laser therapy (ELT) for the treatment of primary symptomatic varicose veins (VV). Background The Ontario Health Technology Advisory Committee (OHTAC) met on November 27, 2009 to review the safety, effectiveness, durability and cost-effectiveness of ELT for the treatment of primary VV based on an evidence-based review by the Medical Advisory Secretariat (MAS). Clinical Condition VV are tortuous, twisted, or elongated veins. This can be due to existing (inherited) valve dysfunction or decreased vein elasticity (primary venous reflux) or valve damage from prior thrombotic events (secondary venous reflux). The end result is pooling of blood in the veins, increased venous pressure and subsequent vein enlargement. As a result of high venous pressure, branch vessels balloon out leading to varicosities (varicose veins). Symptoms typically affect the lower extremities and include (but are not limited to): aching, swelling, throbbing, night cramps, restless legs, leg fatigue, itching and burning. Left untreated, venous reflux tends to be progressive, often leading to chronic venous insufficiency (CVI). A number of complications are associated with untreated venous reflux: including superficial thrombophlebitis as well as variceal rupture and haemorrhage. CVI often results in chronic skin changes referred to as stasis dermatitis. Stasis dermatitis is comprised of a spectrum of cutaneous abnormalities including edema, hyperpigmentation, eczema, lipodermatosclerosis and stasis ulceration. Ulceration represents the disease end point for severe CVI. CVI is associated with a reduced quality of life particularly in relation to pain, physical function and mobility. In severe cases, VV with ulcers, QOL has been rated to be as bad or worse as other chronic diseases such as

Serefeddin Sabuncuoğlu, a pioneer of surgery, is known to be the author of first illustrated surgery textbook, Cerrahiyyetu'l Haniyye (Imperial Surgery), which was written in Turkish in 1465 AD at the age of 80 years. The purpose of this article is to describe his contributions to varicose vein surgery. In addition to vascular surgery, Serefeddin Sabuncuoğlu was interested in a wide range of surgical specialities including thoracic surgery, general surgery, pediatric surgery, ophthalmology, orthopedic surgery, urologic surgery, and obstetrics and gynecology. His book was the first illustrated textbook of surgery in the Turkish medical literature, containing color illustrations of surgical procedures, incisions, and instruments. The book has been known of for only the past 60 years. There are 137 different medical observations and recommendations in Cerrahiyyetu'l Haniyye, along with translated passages from the works of Ebu Kasim-ul Zahravi (Albucasis), Al-Tasrif (Textbook of Surgery), including Sabuncuoğlu's additional original contributions. In chapter 90 of the book, Sabuncuoğlu describes lower extremity varices and their surgical treatment and provides a few color illustrations. Although not recognized and rewarded in his time, Serefeddin Sabuncuoğlu was a great surgeon in Turkish-Islamic medical history. This review demonstrates that his textbook, Cerrahiyyetu'l Haniyye, was the first illustrated textbook including various surgical procedures, incisions, and instruments of varicose vein surgery.

Venous hemodynamic changes after the surgery of primary varicose veins were evaluated. (Materials and methods) We retrospectively analyzed 1,211 patients (1,407 limbs) who underwent surgery for primary varicose veins from 1994 to 2002. The venous hemodynamics were evaluated using air- plethysmography (APG) preoperatively and one month postoperatively in the viewpoints of ambulatory venous pressure (AVP), venous volume (VV), venous filling index (VFI), and ejection fraction (EF). (Results) The surgical modalities included 958 cases of greater saphenous vein high ligation (GSV HL) and stripping with varicosectomy (VS), 222 cases of short saphenous vein (SSV) HL and VS, 143 cases of external banding valvuloplasty of GSV and VS, and 44 cases using VNUS and VS. The reduction rate of VV was 20.9 +/- 14.1% in the GSV stripping group, 12.0 +/- 14.7% in the GSV valvuloplasty group, 18.3 +/- 16.1% in the VNUS group, and 20.6 +/- 15.9% in the SSV group. The reduction rate of VFI was 63.6 +/- 20.7% in the GSV stripping group, 38.8 +/- 40.9% in the GSV valvuloplasty group, 60.1 +/- 23.9% in the VNUS group, and 37.6 +/- 30.2% in the SSV group. The increasing rate of EF was 25.0 +/- 28.2% in the GSV stripping group, 21.0 +/- 30.0% in the GSV valvuloplasty group, 29.4 +/- 31.9% in the VNUS group, and 30.0 +/- 36.5% in the SSV group. The reduction rate of AVP was 25.4 +/- 32.2% in the GSV stripping group, -6.1 +/- 58.1% in the GSV valvuloplasty group, 28.4 +/- 38.5% in the VNUS group, and 14.1 +/- 49.0% in the SSV group. All of the patients showed improvements in venous hemodynamics by showing a decrease in VV, VFI, AVP, and an increase in EF. However, there was no difference in the change of venous hemodynamics according to the type of surgery.

To investigate whether a silicone implant at the sapheno-femoral ligation site could prevent recurrent varicosities. Two non-randomised groups of patients were studied prospectively. In group A 173 patients and 212 limbs had sapheno-femoral ligation, while 172 patients and 210 limbs additionally had a piece (2x3cm) of silicone sheet sutured to the saphenous stump to cover the anterior half of the common femoral vein. The implant was fixed in apposition to the deep vein by carefully closing the cribriform fascia. Colour duplex scanning was performed after 2 and 12 months. In the no implant group neovascularisation was observed in 35 (17%) after 12 months, but only in 13 (6%) limbs treated with a silicone implant (p<0.05). Interposition of a partition of silicone implant seems to lower the incidence of neovascularisation one year after saphenofemoral ligation. This technique may constitute an efficient method to prevent recurrence at the correctly ligated saphenous stump.

The last 10 years have seen the introduction into everyday clinical practice of a wide range of novel non-surgical treatments for varicose veins. In July 2013, the UK National Institute for Health and Care Excellence recommended the following treatment hierarchy for varicose veins: endothermal ablation, ultrasound-guided foam sclerotherapy, surgery and compression hosiery. The aim of this paper is to review the randomised controlled trials that have compared endothermal ablation and ultrasound-guided foam sclerotherapy to determine if the level 1 evidence base still supports an "endothermal ablation first" strategy for the treatment of varicose veins. A PubMed and OVID literature search (until 31 January 2015) was performed and randomised controlled trials comparing endothermal ablation and ultrasound-guided foam sclerotherapy were obtained. Although anatomical success appeared higher with endothermal ablation than ultrasound-guided foam sclerotherapy, clinical success and patient-reported outcomes measures were similar. Morbidity and complication rates were very low and not significantly different between endothermal ablation and ultrasound-guided foam sclerotherapy. Ultrasound-guided foam sclerotherapy was consistently less expensive that endothermal ablation. All endovenous modalities appear to be successful and have a role in modern day practice. Although further work is required to optimise ultrasound-guided foam sclerotherapy technique to maximise anatomical success and minimise retreatment, the present level 1 evidence base shows there is no significant difference in clinical important outcomes between ultrasound-guided foam sclerotherapy and endothermal ablation. As ultrasound-guided foam sclerotherapy is less expensive, it is likely to be a more cost-effective option in most patients in most healthcare settings. Strict adherence to the treatment hierarchy recommended by National Institute for Health and Care Excellence seems unjustified. © The Author

Influence of Syringe Volume on Foam Stability in Sclerotherapy for Varicose Vein Treatment.

2018-05-01

Despite the popularity of sclerotherapy for treating varicose veins, it still exhibits various problems, such as pulmonary embolism, deep-vein thrombosis, phlebitis, and visual disorders. To investigate syringe volume influence on foam stability, obtain the foam decay rule, and provide a reference for clinics. Five types of syringes are used to prepare foam at room temperature with various liquid-gas ratios. Foam decay process experiments were performed 5 times and recorded by video. The stability indices used include drainage time, half-life, bubble diameter, bubble surface density, and drainage rate. The 30 and 2-mL syringes, respectively, recorded the highest and lowest drainage speeds. Foam drainage time and half-life, differences varied between 15 and 70 seconds, and 20 and 100 seconds, respectively. Foam bubble diameters were distributed over 0.1 to 2.0 mm with roughly 200 to 700 bubbles per square centimeter. Increased syringe volume causes the bubble diameter to increase. Thus, foam dispersion increases and foam half-life decreases; hence, foam becomes unstable. It is, thus, better to use a small syringe several times to prepare foam in clinics using segmented injections.

To investigate the effectiveness of bipolar radiofrequency-induced thermal therapy (RFITT) in a multicentre non-randomized study. Some 672 incompetent saphenous veins (85% great saphenous varicose vein, 15% short saphenous vein) in 462 patients (56.5% CEAP [clinical, aetiological, anatomical and pathological elements] class 3 or worse) were treated in eight European centres. Patients were assessed between 180 and 360 days postoperatively. Occlusion rates were determined by duplex ultrasound and compared with the power used for treatment, pull back rate and experience of the operating surgeon. Complete occlusion rates of 98.4% were achieved when treatments were performed by an experienced operator (more than 20 cases), when the maximum power setting on the RFITT generator was between 18 and 20 W and the applicator was withdrawn at a rate slower than 1.5 second/cm RFITT is efficacious, well tolerated by patients and has a low incidence of procedure-related post-operative complications.

Evidence for unmyelinated C fibres and inflammatory cells in human varicose saphenous vein

Vital, Anne; Carles, Dominique; Serise, Jean-Michel; Boisseau, Michel René

2010-01-01

The physiopathology of venous symptoms, such as pain, leg heaviness or swelling sensations, in chronic venous disease (CVD) remains unclear. Localized release of proinflammatory mediators appears to play a key role but the presence of nociceptors sensitive to inflammatory mediators, such as unmyelinated C fibres, needs to be demonstrated. The present study included 10 patients with documented CVD who underwent surgery for saphenectomy. For each patient, five segments of the great saphenous vein were immunostained with anti-S100 protein and anti-CD45 to identify nerve fibres and inflammatory cells, respectively. Light microscopy was completed by electron microscopy. In all patients, S100 immunopositive nerve fibres and CD45 immunopositive cells were observed. Under an electron microscope, advanced signs of wall remodelling were systematically observed. The density of nerve fibres was low and variable from one sample to another. Unmyelinated C fibres were mainly located in the external part of the media and to a lesser extent in the internal part of the adventitia. Inflammatory cells, mainly histiocytes, were scattered in the media. Mast cells were observed in three patients. In conclusion, unmyelinated C fibres and inflammatory cells are present in the varicose saphenous vein wall. Their linked roles in symptoms of CVD should be further explored. PMID:22477593

Female Pelvic Vein Embolization: Indications, Techniques, and Outcomes

Lopez, Anthony James, E-mail: consultant@radiologist.co.uk

Until recently, the main indication for pelvic vein embolization (PVE) in women was to treat pelvic venous congestion syndrome (PVC) but increasingly, patients with refluxing pelvic veins associated with leg varicosities are also being treated. A more unusual reason for PVE is to treat pelvic venous malformations, although such lesions may be treated with sclerotherapy alone. Embolotherapy for treating PVC has been performed for many years with several published studies included in this review, whilst an emerging indication for PVE is to treat lower limb varicosities associated with pelvic vein reflux. Neither group, however, has been subjected to an adequatemore » randomized, controlled trial. Consequently, some of the information presented in this review should be considered anecdotal (level III evidence) at this stage, and a satisfactory ‘proof’ of clinical efficacy remains deficient until higher-level evidence is presented. Furthermore, a wide range of techniques not accepted by all are used, and some standardization will be required based on future mandatory prospective studies. Large studies have also clearly shown an unacceptably high recurrence rate of leg varicose veins following venous surgery. Furthermore, minimally or non-invasive imaging is now revealing that there is a refluxing pelvic venous source in a significant percentage of women with de novo leg varicose veins, and many more with recurrent varicosities. Considering that just over half the world’s population is female and a significant number of women not only have pelvic venous reflux, but also have associated leg varicosities, minimally invasive treatment of pelvic venous incompetence will become a common procedure.« less

Background The aim of this study was to evaluate the midterm clinical outcomes after modified high ligation and segmental stripping of small saphenous vein (SSV) varicosities. Methods Between January 2010 and March 2013, 62 patients (69 legs) with isolated primary small saphenous varicose veins were enrolled in this study. The outcomes measured were reflux in the remaining distal SSV, the recurrence of varicose veins, the improvement of preoperative symptoms, and the rate of postoperative complications. Results No major complications occurred. No instances of the recurrence of varicose veins at previous stripping sites were noted. Three legs (4.3%) showed reflux in the remaining distal small saphenous veins. The preoperative symptoms were found to have improved in 96.4% of the cases. Conclusion In the absence of flush ligation of the saphenopopliteal junction, modified high ligation and segmental stripping of small saphenous vein varicosities with preoperative duplex marking is an effective treatment method for reducing postoperative complications and the recurrence of SSV incompetence.

VARICOSE VEINS—A Practical Approach to Treatment

Ellenburg, Robert

Adequate treatment of varicose veins requires thorough mapping of perforating veins, communicating veins and “blow out” areas. Combined ligations, stripping and injection of sclerotic substances after operation is the most effective regimen of therapy. The technique of stripping is facilitated by isolating the saphenous vein at the ankle, inserting the stripper from below upward, then making a transverse groin incision over the palpable stripper. The tip of the stripper should be twice the diameter of the vein to be removed. Stripping should be done with the patient in the Trendelenburg position. All patients must be examined at regular intervals after operation and injection of sclerosing material carried out as necessary. PMID:13523415

Impact of radiofrequency ablation for patients with varicose veins on the budget of the German statutory health insurance system

PubMed Central

2013-01-01

Objectives In contrast to other countries, surgery still represents the common invasive treatment for varicose veins in Germany. However, radiofrequency ablation, e.g. ClosureFast, becomes more and more popular in other countries due to potential better results and reduced side effects. This treatment option may cause less follow-up costs and is a more convenient procedure for patients, which could justify an introduction in the statutory benefits catalogue. Therefore, we aim at calculating the budget impact of a general reimbursement of ClosureFast in Germany. Methods To assess the budget impact of including ClosureFast in the German statutory benefits catalogue, we developed a multi-cohort Markov model and compared the costs of a “World with ClosureFast” with a “World without ClosureFast” over a time horizon of five years. To address the uncertainty of input parameters, we conducted three different types of sensitivity analysis (one-way, scenario, probabilistic). Results In the Base Case scenario, the introduction of the ClosureFast system for the treatment of varicose veins saves costs of about 19.1 Mio. € over a time horizon of five years in Germany. However, the results scatter in the sensitivity analyses due to limited evidence of some key input parameters. Conclusions Results of the budget impact analysis indicate that a general reimbursement of ClosureFast has the potential to be cost-saving in the German Statutory Health Insurance. PMID:23551943

There is controversy in the surgical management of varicose veins between stripping of the long saphenous vein (LSV) and high ligation. Moreover, preservation of the LSV is desirable for future coronary or peripheral artery bypass. We have studied 75 limbs in 44 patients after high saphenous ligation with multiple stab phlebectomy. Subjective assessment of the outcome of surgery was made with a linear analog scale, and objective cosmetic outcome was assessed by an independent observer (LF) who had not been involved in the surgical treatment of these patients with our modification from the criteria first described by Jakobsen. Patency, length, and diameter of the LSV was measured 6 to 14 months (mean 12 months) after operation with a duplex scanner and a color-flow scanner. Valvular incompetence in the LSV and perforators was also assessed. Results show a good subjective and objective outcome in 95% and 97% of limbs, respectively. The LSVs were patent from ankle to groin in 68% and from ankle to knee in 82%, with a mean diameter of 4.0 +/- 0.1 mm (mean +/- SEM). There was no statistically significant difference in symptomatic outcome and presence of reflux in the LSV (X2 = 0.465; p = 0.4954; NS) or objective cosmetic outcome and the presence of reflux in the LSV (chi 2 = 2.916; p = 0.0877; NS). It is concluded that high saphenofemoral ligation combined with multiple "stab avulsions" preserves an LSV with characteristics suggesting suitability for future use as a vascular prosthesis with good early symptomatic and cosmetic results.

Quantitative comparison between radial and cylindrically diffusing fibers for photothermal treatment of varicose vein disease (Conference Presentation)

For last two decades, endovenous laser therapy (EVLT) is one of the most widely accepted surgical options for treating incompetent great and small saphenous veins. However, due to excessive heating during EVLT, the major complications include pain and burning that often increase the risk of dermatitis disease. The aim of the current study was to quantitatively compare commercially-available radial fibers with newly-developed diffusing applicators for 1470 nm-EVLA in terms of temperature elevation and vein deformation. Rabbit veins were used as an ex vivo model for EVLA. A 5-W 1470 nm laser system in conjunction with the radial and diffusing fibers was employed to thermally coagulate the venous tissue. A goniometric measurement validated uniform and isotropic distribution of laser light in polar and longitudinal directions (i.e., normalized intensity = 0.84±0.08). The diffusing applicator induced a 20 % lower maximum temperature than the radial fiber did (maximum temperature = 79.2 °C for radial vs. 63.3 °C for diffusing). Due to higher irradiance, the radial fiber was associated with a transient temperature change of 5.9 °C/s, which was 1.5-fold faster than the diffusing applicator (i.e., 2.4 °C/s). However, the degree of cross-sectional area reduction in the veins was almost comparable for both the fibers (i.e., 53% for radial vs. 48% for diffusing). Due to longer irradiation length, the diffusing applicator demonstrated wider treatment coverage and less fiber speed-dependent. On account of easy pullback technique and uniform thermal effect, the proposed cylindrically diffusing applicator can be a feasible optical device to effectively treat varicose veins. Further in vivo studies will be performed to identify the complete removal of the vein disease and healing response of the venous tissue.

The article deals with the findings obtained in examining a total of 8,000 people presenting with varicose disease of the lower extremities. The examination included a clinical (physical) examination and coloured duplex scanning of the lower-limb veins. The examination was carried out in outpatient conditions, whereas surgical treatment was performed either out-patiently, or at a hospital. Revealing complete valvular insufficiency of the great saphenous vein was followed by surgical treatment - intraoperative stem catheter scleroobliteration (SSO) or short-term screening and postoperative puncture sclerotherapy. Detecting partial valvular insufficiency of the greater saphenous vein (pathological sapheno-femoral reflux only in the vertical position) was managed by applying the principle of the so-called : i. e. the patients were subjected to the procedure of puncture sclerotherapy of varicose veins on the crus in ambulatory conditions to be followed by secondary ultrasonographic scanning with permanent dynamic follow-up. The cases of preserved reflux along the greater saphenous vein were subjected to sclerosurgical management. Valvular insufficiency of perforating veins was coped with by minimally invasive surgical interventions: subtotal endoscopic dissection of incompetent perforating veins, suprafascial ligation from a miniaccess and echosclerotherapy of the perforating veins. Also performed were histological and histochemical studies of the portions the greater saphenous vein and surrounding tissues procured during cross-ectomy of the sapheno-femoral anastomosis in 43 patients, who had endured preliminary puncture sclerotherapy on the crus. Good functional and cosmetically pleasing outcomes were achieved in the majority of cases. In 75% of the patients with partial valvular insufficiency of the greater saphenous vein, we managed to avoid operations since repeat ultrasonographic study revealed no pathological veno-venous shunts.

Background Since the 1990s, new techniques for the treatment of varicose veins have emerged, including radiofrequency ablation (RFA) and laser treatment. We performed a study to compare the safety, efficacy and outcomes of RFA compared to those of open surgery and laser ablation for the treatment of varicose veins. We also carried out a cost analysis of RFA compared to open surgery to assess whether RFA could help free up operating room time by being performed in an outpatient context. Methods We conducted a systematic literature review (publication date May 2010–September 2013 for articles in English, January 1991–September 2013 for those in French). We used several checklists to measure the quality of the studies. We also collected data on costing. Results The literature search identified 924 publications, of which 38 were retained for analysis: 15 literature reviews, 1 good-practice guideline and 22 new primary studies. The overall level of evidence was low to moderate owing to the limited sample sizes, lack of information on patient characteristics and lack of standardization of the outcome measures. However, the results obtained are consistent from study to study. In the short and medium term, RFA is considered as effective as open surgery or laser treatment (moderate level of evidence) and presents fewer major and minor complications than open surgery (low level of evidence). Radiofrequency ablation can be performed on an outpatient basis. We calculated that RFA would be about $110–$220 more expensive per patient than open surgery. Conclusion Radiofrequency ablation is a valuable alternative to open surgery and would free up operating room time in a context of low accessibility. PMID:29582749

In homeopathy ARNICA is widely used as a woundhealing medication and for the treatment of hematomas. In this pilot study the efficacy and safety of ARNICA D12 in patients following varicose vein surgery were investigated. Prospective, randomized, double-blind, placebo-controlled pilot trial according to ICH GCP guidelines. The study was conducted by a surgeon at the Angiosurgical Clinic, Berlin- Buch. After randomized allocation, 60 patients received either ARNICA D12 or placebo. Start of medication occurred the evening before operation with 5 globules. On the operation day one preoperative and hourly postoperative dosages after awakening were given. On days 2-14 of the study 5 globules 3 times a day were given. OUTCOME CRITERIA: Surface (in cm(2) and using a three-point verbal rating scale) and intensity of hematomas induced by operation, complications of wound healing, and intensity of pain (five-point verbal rating scale) as well as efficacy and safety of the study medication were assessed. Hematoma surface was reduced (from day 7 to day 14) under ARNICA by 75.5% and under placebo by 71.5% (p = 0.4726). The comparison of hematoma surface (small, medium, large) using the verbal rating scale yielded a value of p = 0.1260. Pain score decreased by 1.0 +/- 2.2 points under ARNICA and 0.3 +/- 0.8 points under placebo (p = 0.1977). Remission or improvement of pain was observed in 43.3% of patients in the ARNICA group and in 27.6% of patients in the placebo group. Tolerability was rated as very good in all cases. The results of this pilot study showed a trend towards a beneficial effect of ARNICA D12 with regard to reduction of hematoma and pain during the postoperative course. For a statistically significant proof of efficacy of ARNICA D12 in patients following varicose vein surgery a larger sample size is necessary. Copyright 2003 S. Karger GmbH, Freiburg

Endovenous thermal ablation (ETA) procedures are catheter-directed, ultrasound (US)-guided thermal methods for treatment in varicose veins disease. Radiofrequency, laser or steam energy thermally denatures vein wall collagen, leading first to vein wall inflammation, then fibrosis and finally to occlusion. The aim of this guideline is to give evidence-based recommendations for ETA procedures. These guidelines were drafted during a consensus meeting of a group of experts in the field of ETA in June 2012 (Hvar, Croatia) under the auspices of the International Union of Phlebology (IUP). These guidelines review the present state of knowledge as reflected in peer-reviewed published medical literature. The recommendations of these guidelines are graded according to the American College of Chest Physicians Task Force recommendations on Grading Strength of Recommendations and Quality of Evidence in Clinical Guidelines. Recommendations on the use of ETA procedures were made based on the quality of evidence for efficacy, safety, tolerability, cosmetic outcome, patient satisfaction/preference and, where appropriate, on the experts' opinion. Health economics were not considered, since differences in national health systems and pricing make it difficult to form general conclusions that are relevant at an international level. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

The aim of this open study was the evaluation of the effects of HR (Venoruton) at a dose of 1 g/day on the prevention and control of flight microangiopathy and edema in subjects with varicose veins and moderate chronic venous insufficiency flying for more than 11 hours. Patients with varicose veins, edema, but without initial skin alterations or complications, were included. Measurements of skin laser Doppler (LDF) resting flux (RF) venoarteriolar response (VAR), ankle swelling (RAS), and edema were made within 12 hours before and within 3 hours after the flights. The resulting edema after the flights was evaluated with a composite edema score (analogue scale line). A group of 20 subjects was treated with HR (1 g/day, starting 2 days before the flight and 1 g for every 12 hours on day of travel). Another group of 18 subjects formed the control group. The length of the flights was between 11 and 13 hours; all seats were in coach class. Fifty patients were enrolled and 38 patients were evaluable at the end of the trial. The 2 groups (treatment and control) were comparable for age and sex distribution. The decrease in RF was significant in both groups with a higher flux at the end of the flight in the HR group (p < 0.05). The venoarteriolar response was decreased at the end of the flights; the decrease was lower in the HR group (p < 0.05). The increase in RAS and the edema score were significantly lower in the HR group. In conclusion HR is useful for reducing the level of microangiopathy and the increased capillary filtration and in controlling edema in patients with venous disease in long flights. The higher level of flux and VAR and the reduction in edema indicate a positive effect of HR on the microcirculation. This study confirms that HR prophylaxis is effective to control flight microangiopathy associated with edema.

Chronic deep vein thrombosis (DVT) affects hundreds of thousands of women in the United States. Chronic DVT can lead to pain, edema, venous ulcers, and varicosities. While there are limited data regarding the management of chronic DVT, several interventional radiology groups aggressively treat chronic DVT to aid patient symptom resolution. Recanalization of occluded veins and venous stenting re-establishes deep vein flow and decreases venous hypertension.

Imaging of subcutaneous veins is important in many applications, such as gaining venous access and vascular surgery. Despite a long history of medical infrared (IR) photography and imaging, this technique is not widely used for this purpose. Here we revisited and explored the capability of near-IR imaging to visualize subcutaneous structures, with a focus on diagnostics of superficial veins. An IR device comprising a head-mounted IR LED array (880 nm), a small conventional CCD camera (Toshiba Ik-mui, Tokyo, Japan), virtual-reality optics, polarizers, filters, and diffusers was used in vivo to obtain images of different subcutaneous structures. The same device was used to estimate the IR image quality as a function of wavelength produced by a tunable xenon lamp-based monochrometer in the range of 500-1,000 nm and continuous-wave Nd:YAG (1.06 microm) and diode (805 nm) lasers. The various modes of optical illumination were compared in vivo. Contrast of the IR images in the reflectance mode was measured in the near-IR spectral range of 650-1,060 nm. Using the LED array, various IR images were obtained in vivo, including images of vein structure in a pigmented, fatty forearm, varicose leg veins, and vascular lesions of the tongue. Imaging in the near-IR range (880-930 nm) provides relatively good contrast of subcutaneous veins, underscoring its value for diagnosis. This technique has the potential for the diagnosis of varicose veins with a diameter of 0.5-2 mm at a depth of 1-3 mm, guidance of venous access, podiatry, phlebotomy, injection sclerotherapy, and control of laser interstitial therapy.

A CONTROLLED TECHNIQUE FOR VEIN STRIPPING

PubMed Central

Gordon, Milton; Payne, Robert D.

1953-01-01

A number of difficulties encountered in vein stripping operations for varicose veins in the legs have been overcome by use of a technique evolved by adaptation and modifications of various reported methods. The stripping instrument is passed from below upward, the valves or branches offering less impediment to its passage in that direction. Inserting the tip of the instrument at the ankle through an incision in the vein while it is still in continuity is easier than introducing it into the end of a transected vein. Ligation of major superficial branches or subfascial division of communicating veins can be readily carried out while the stripper is still in place in the vein. Applying pressure bandages to the entire length of the leg before removing the stripper and the telescoped vein diminishes the chances of ecchymosis yet does not hinder withdrawal of the instrument and the vein.

Prosthetic arteriovenous grafts (AVGs) are associated with greater morbidity than autogenous arteriovenous fistulas (AVFs), but their use is indicated when AVF formation is not possible. This report adds to the literature a case of lower limb gigantism, painful varicosities, and lymphedema following long-term use of AVG in the upper thigh. The patient's past medical history included renal transplantation on the same side well before the AVG was inserted and right leg deep vein thrombosis. Suspicion of AVG thrombosis was excluded by Doppler ultrasound, which demonstrated an access flow of 1700 mL/min. A computed tomography (CT) scan of the abdomen and pelvis did not identify the cause of her symptoms. Whereas functional incompetence of the iliac vein valve might be responsible for the varicosities, the extent of hypertrophy in this case raises the suspicion of lymphatic blockage possibly secondary to groin dissection undertaken at the time of graft insertion, in addition to the previous dissection at the time of transplantation. This case highlights the need for minimal groin dissection during AVG insertion, particularly in patients with a history of previous abdominopelvic surgery. © 2014 International Society for Hemodialysis.

Objective This study compared the risk of varicose veins (VV) among physicians, nonphysician health care providers (HCP), and the general population. Subjects and Methods The Taiwan National Health Insurance Research Database was used to identify 28,844 physicians and 26,099 nonphysician HCP and an identical number of age- and sex-matched patients from the general population. Using logistic regression analyses, VV risks between physicians and the general population, nonphysician HCP and the general population, and physicians and nonphysician HCP, and among physician specialists were compared by tracing their medical histories between 2007 and 2011. Results Physicians and nonphysician HCP had cumulative VV incidences of 0.12% (34/28,844) and 0.13% (33/26,099), respectively, during the 5-year period, compared to that of the general population within the same 5-year period. Physicians and nonphysician HCP did not have a higher VV risk than the general population after adjusting for deep vein thrombosis (DVT) history (adjusted odds ratio [AOR] 0.86; 95% confidence interval [CI] 0.53–1.40, and AOR 1.43; 95% CI 0.82–2.50, respectively). Physicians did not a have higher VV risk than nonphysician HCP (AOR 0.80; 95% CI 0.43–1.51) after adjusting for age, sex, and DVT history. Surgery had the highest incidence (0.22%) while pediatrics and emergency medicine had the lowest incidence (0%) of VV risk among physician specialists; however, the difference was not significant (all p values >0.05). Conclusion In this study, VV risk did not differ among physicians, nonphysician HCP, and the general population. PMID:28249260

Three of four (75%) vein biopsy samples from four patients (all male, mean onset: age 33.0, mean biopsy: age 59.7) of chronic phase phlebitis migrans showed positive periodontal bacteria DNA under the PCR (polymerase chain reaction) method. Of the 24 cases of Buerger disease (22 males, 2 females, mean onset: age 31.9, mean examination: age 62.6) that were investigated in our vascular laboratory, 65% of the patients suffered from moderate to severe varicose veins. Eight cases had a history of phlebitis migrans and three had an active ulcer or uncontrollable erosion in the foot. The rate of incidence was significantly higher than that of the well-matched control group. Other findings included one instance of deep vein thrombosis, and one instance of deep vein reflux. We could suggest that some intractable ulcer or erosion cases of Buerger disease may be complicated by superficial vein incompetence or other deep vein insufficiency. We also we need to check Buerger disease patients with duplex for vein reflux and other insufficiencies. Treatment of the varicose veins (including elastic stockings) was effective for all of the patients. (English Translation of Jpn J Phlebology 2011; 22: 25–31.) PMID:23555485

Varicose veins (VVs) cluster in families, but the familial risk of VVs has not been determined among adoptees. The aim was to estimate whether the familial transmission of VVs is related to disease in biological and/or adoptive parents. The Swedish Multi-Generation Register and the Swedish Patient Register were used to follow all Swedish-born adoptees (born 1932 through 2004) that could be linked to both their biological and their adoptive parents (n = 80,214; 50% females). The risk of VVs was estimated in adoptees with at least 1 biological parent with VVs, but no adoptive parent with VVs (n = 187) compared with adoptees without a biological or adoptive parent with VVs (n = 1,758). The risk of VVs was also determined in adoptees with at least 1 adoptive parent, but no biological parent with VVs (n = 87), and in adoptees with both biological and adoptive parents affected (n = 21). Adoptees from an affected biological parent, but no adoptive parent, were more likely to have VVs than adoptees from an unaffected biological or adoptive parent (standard incidence ratio [SIR] = 2.21; 95% CI, 1.91-2.55). The familial SIR for adoptees with both an affected biological parent and an adoptive parent was 4.58 (95% CI, 2.83-7.01). Adoptees with an affected adoptive parent but no biological parent were not at increased risk of VVs (SIR = 1.15; 95% CI, 0.92-1.42). These novel findings suggest that genetic factors make a strong contribution to the familial transmission of VVs from parents to offspring, although familial environmental factors might contribute.

We report on new stripper guides that facilitate the introduction of the stripper from the proximal side. At the same time they allow for smaller skin incisions and fewer nerve lesions. The 60-cm-long cable instead of the conventional one (90 cm long) is adequate for partial stripping. Due to its shortness, it is less annoying in the operation field and it allows rotational control of the Tiemann guide. The "dolphin" and the "torpedo" help to remove segments of the saphenous vein that are left behind. All these instruments are available as a set in a small box, which is handy for the scrub nurse.

Venous Thromboembolism and Varicose Veins Share Familial Susceptibility: A Nationwide Family Study in Sweden

Background Varicose veins (VVs) have been associated with venous thromboembolism (VTE), but whether these diseases share familial susceptibility has not been determined. This nationwide study aimed to determine whether VTE shares familial susceptibility with VVs. Methods and Results Swedish Multigeneration Register data for persons aged 0 to 76 years during the period 1964–2008 were linked to the Swedish Inpatient and Outpatient Registers. Familial risks (standardized incidence ratios [SIRs]) of VTE and VVs were examined in 2 ways (ie, bidirectionally): risk of VTE in subjects whose siblings had been diagnosed with VVs and risk of VVs in persons whose siblings had been diagnosed with VTE. The analyses were repeated for spouses to determine the importance of shared adult family environment. In total, 96 810 siblings had VVs and 87 564 had VTE. An increased risk of VTE was observed in persons whose siblings had VVs (SIR 1.30, 95% CI 1.26 to 1.33), whereas persons whose siblings had VTE had an increased risk of VVs (SIR 1.30, 95% CI 1.27 to 1.34). If 2 or more siblings were affected by VTE, the risk for VVs was 1.70 (95% CI 1.53 to 1.88). Conversely, if 2 or more siblings were affected by VVs, the risk for VTE was 1.52 (95% CI 1.38 to 1.67). In spouses of VTE patients, a minor increased risk of VVs was observed (SIR 1.05 for husbands, SIR 1.06 for wives). The risk of VTE in spouses of VV patients was similarly small (SIR 1.01 for husbands, SIR 1.05 for wives). Conclusions VVs and VTE share familial susceptibility. This novel finding suggests the existence of shared familial and possibly genetic factors. PMID:25158864

Law enforcement is interested in exploiting tattoos as an information source to identify, track and prevent gang-related crimes. Many tattoo image retrieval systems have been described. In a retrieval system tattoo segmentation is an important step for retrieval accuracy since segmentation removes background information in a tattoo image. Existing segmentation methods do not extract the tattoo very well when the background includes textures and color similar to skin tones. In this paper we describe a tattoo segmentation approach by determining skin pixels in regions near the tattoo. In these regions graph-cut segmentation using a skin color model and a visual saliency map is used to find skin pixels. After segmentation we determine which set of skin pixels are connected with each other that form a closed contour including a tattoo. The regions surrounded by the closed contours are considered tattoo regions. Our method segments tattoos well when the background includes textures and color similar to skin.

Pigmented oral lesions compose a large number of pathological entities, including exogenous pigmentat oral tattoos, such as amalgam and graphite tattoos. We report a rare case of a graphite tattoo on the palate of a 62-year-old patient with a history of pencil injury, compare it with amalgam tattoos, and determine the prevalence of oral tattoos in our Oral Pathology Service. We also compare the clinical and histological findings of grafite and amalgam tattoos. Oral tattoos affect women more frequently in the region of the alveolar ridge. Graphite tattoos occur in younger patients when compared with the amalgam type. Histologically, amalgam lesions represent impregnation of the reticular fibers of vessels and nerves with silver, whereas in cases of graphite tattoos, this impregnation is not observed, but it is common to observe a granulomatous inflammatory response, less evident in cases of amalgam tattoos. Both types of lesions require no treatment, but in some cases a biopsy may be done to rule out melanocytic lesions.

The greater proportion of oxygen in the blood circulating in veins of the lower limbs bought to attention the possibility of pre-capillary arteriovenous shunting. The intra-arteriel injection of Technetium labelled serum albumin microspheres enables one to quantify arteriovenous shunts greater than 25 microns. The authors made a comparative study of arterio-venous shunting by blood gases analysis and isotopic techniques in twenty patients. The results seem to deny the existence of arteriovenous shunts in the genesis of essential varicose veins in the lower limb.

In the last twenty years, the prevalence of individuals with tattoos in the general population has increased in Europe (1) as well as in Australia (2) and the United States of America (3). A series of complications such as acute inflammatory reactions, allergic contact dermatitis (4,5), photoinduced, lichenoid, and granulomatous reactions (6, 7), pseudolymphoma (8), pseudoepitheliomatous hyperplasia (9), skin infections (6), and skin cancers (10) may occur on tattoos. Infectious complications on tattoos include bacterial infections (pyoderma, leprosy, syphilis, cutaneous tuberculosis, mycobacteriosis) (11-14), viral infections (molluscum contagiosum, warts, herpes simplex, hepatitis B and C) (15-17), and fungal infections (sporotrichosis, dermatophytosis) (18,19). We present the case of a 29-year-old immunocompetent female patient who was consulted for the development of an erythematous-squamous placard that appeared on a tattoo about 18 days after tattooing. Dermatological examination revealed a circular, erythematous, scaly plaque, with centrifugal growth and central resolution, presenting an active, raised, erythematous, vesiculopustular edge, giving the appearance of tinea corporis. The lesion's starting point was on the tattoo in two colors located on the middle third of the left calf and subsequently evolved to beyond the surface of tattoo (Figure 1). No other skin, scalp, or nail lesions were observed. Mycological examination of the material obtained by scraping of the scales and the vesicles from the edges and the surface of the plaque revealed numerous hyphae on direct microscopy examination, and white, flat colonies with a cottony surface and radial grooves developed in Sabouraud dextrose agar culture (Figure 2). Spindle-shaped, thick-walled macroconidia and a few pyriform microconidia were observed on microscopic examinations of the colonies. Based on macroscopic and microscopic characteristics, Microsporum canis was identified. Gram stain and bacterial

Contraindications for tattooing.

Tattooing is getting increasingly popular among the young. However, not everyone is suited to getting tattooed. Indeed, it is not rare for patients with a chronic skin disease or another systemic condition to be eager to get a tattoo. They perceive tattooing as a harmless, risk-free procedure. Therefore, some patients may not seek medical advice before the procedure. Some also fear a judgmental approach by their physician, who may try to discourage them. Lastly, the tattooist does not have either the training or the education to properly advise a customer about his/her condition. Therefore, it is important that any physician be able to provide adequate counselling regarding the possibility of getting tattooed and under which conditions. Even though an exhaustive list is impossible to address, the main issues include chronic skin disorders, pigmented lesions of the skin, (congenital) heart disease, immunosuppressive diseases and treatments, blood clotting disorders, and pregnancy/breastfeeding. © 2015 S.

Tattoo pigments are deposited in the skin and known to distribute to regional lymph nodes. Tattoo pigments are small particles and may be hypothesized to reach the blood stream and become distributed to peripheral organs. This has not been studied in the past. The aim of the study was to trace tattoo pigments in internal organs in mice extensively tattooed with 2 different tattoo ink products. Three groups of mice were studied, i.e., 10 tattooed black, 10 tattooed red, and 5 untreated controls. They were tattooed on the entire back with commercial tattoo inks, black and red. Mice were sacrificed after 1 year. Samples were isolated from tattooed skin, lymph nodes, liver, spleen, kidney, and lung. Samples were examined for deposits of tattoo pigments by light microscopy and transmission electron microscopy (TEM). TEM identified intracellular tattoo pigments in the skin and in lymph nodes. TEM in both groups of tattooed mice showed tattoo pigment deposits in the Kupffer cells in the liver, which is a new observation. TEM detected no pigment in other internal organs. Light microscopy showed dense pigment in the skin and in lymph nodes but not in internal organs. The study demonstrated black and red tattoo pigment deposits in the liver; thus, tattoo pigment distributed from the tattooed skin via the blood stream to this important organ of detoxification. The finding adds a new dimension to tattoo pigment distribution in the body, i.e., as observed via the blood in addition to the lymphatic pathway. © 2017 S. Karger AG, Basel.

From Technique of Tattooing to Biokinetics and Toxicology of Injected Tattoo Ink Particles and Chemicals.

PubMed

Serup, Jørgen

Tattoo colourants are colourful nano- and microparticles, which are practically insoluble and thus permanent once installed in the dermis by the tattooist. Tattoo ink also has soluble ingredients and contaminants. Pigments can distribute via the lymph and possibly also directly to the blood, and a minute fraction may over time undergo metabolic breakdown and as hapten(s) induce allergic reactions of red tattoos. Carbon black of black tattoos has a tendency to agglomerate and form larger bodies that can elicit foreign body reactions in black tattoos and even granuloma formation with overlap to sarcoidosis in the clinic. Very little is known about the biokinetics and safety profile of the many tattoo pigments in use, and no specific pigment-related chemical of tattoo ink causing identified adverse reactions in humans has been depicted. Inks have many ingredients and contaminants. Insoluble and soluble ingredients of inks supposedly have very different characteristics of absorption, distribution, metabolism, and excretion, with pigments being extremely slowly excreted, contrasting soluble ingredients with fast elimination. Tattoos are a single-dose exposure. Controlling the safety of tattoo inks by banning potentially critical chemicals hitherto has been unsuccessful due to lacking documentation of clinical and epidemiological relevance and because the tattoo industry is already internationally established, free, and in the ownership of the people. Doctors treating patients with tattoo complications consequently have a key role in identifying risk situations and local outbreaks, which needs clarification, therapy, and the intervention of authorities. In the treatment of complications, as seen in general practice and in other specialties, basic insight into the fate of tattoo pigments in the body is necessary. Tattoo complications are complicated and facetted with many entities and disease mechanisms; they are a new subspecialty in medicine and dermatology. © 2017 S

To prospectively investigate the feasibility of an 80-kilovolt (peak) (kVp) protocol in computed tomographic venography for varicose veins of the lower extremities by comparison with conventional 120-kVp protocol. Attenuation values and signal-to-noise ratio of iodine contrast medium (CM) were determined in a water phantom for 2 tube voltages (80 kVp and 120 kVp). Among 100 patients, 50 patients were scanned with 120 kVp and 150 effective milliampere second (mAs(eff)), and the other 50 patients were scanned with 80 kVp and 390 mAs(eff) after the administration of 1.7-mL/kg CM (370 mg of iodine per milliliter). The 2 groups were compared for venous attenuation, contrast-to-noise ratio, and subjective degree of venous enhancement, image noise, and overall diagnostic image quality. In the phantom, the attenuation value and signal-to-noise ratio value for iodine CM at 80 kVp were 63.8% and 33.0% higher, respectively, than those obtained at 120 kVp. The mean attenuation of the measured veins of the lower extremities was 148.3 Hounsfield units (HU) for the 80-kVp protocol and 94.8 HU for the 120-kVp protocol. Contrast-to-noise ratio was also significantly higher with the 80-kVp protocol. The overall diagnostic image quality of the 3-dimensional volume-rendered images was good with both protocols. The subjective score for venous enhancement was higher at the 80-kVp protocol. The mean volume computed tomography dose index of the 80-kVp (5.6 mGy) protocol was 23.3% lower than that of the 120-kVp (7.3 mGy) protocol. The use of the 80-kVp protocol improved overall venous attenuation, especially in perforating vein, and provided similarly high diagnostic image quality with a lower radiation dose when compared to the conventional 120-kVp protocol.

Tattoo art has been around for thousands of years in every culture and is currently flourishing in all age groups, social classes, and occupations. Despite the rising popularity of tattoos, demand for their removal has also increased. While various treatments, including surgical excision, dermabrasion, and chemical destruction have historically been applied, over the past 2 decades, lasers have revolutionized the way tattoos are treated and have become the gold standard of treatment. To achieve optimal cosmetic outcome of treatment, lasers emitting high energies and short pulses are required to adequately destroy tattoo ink. We review the history of laser tattoo removal, outlining the challenges inherent in developing lasers that can most effectively remove tattoo particles while safely protecting skin from unwanted injury.

Tattoo and taboo: on the meaning of tattoos in the analytic process.

PubMed

Karacaoglan, Uta

2012-02-01

Tattooing projects a visual image in transference to form a backdrop for the most salient unconscious inner conflicts arising during an ongoing analytic process. Like a snapshot, the tattoo is a dialectic record of the mother-father relationship, of desires for closeness and distance, commonality and difference, identification and individuation. As Walter Benjamin famously stated about the nature of visual images in his Arcades Project, the tattoo represents "dialectics at a standstill." What seems paramount to the patient who participates in the act of tattooing is the need for stasis and immutability, as if bringing unconscious conflicts to "standstill" were to deliver a sense of stability. Unconsciously, the need is triggered by a threat to the inner stability resulting from fear of violating a taboo escalating to the point that fears of abandonment and fusion become unbearable. On the one hand, the tattoo is a visual symbolization of a taboo transgression; on the other hand, it activates the same through an act of self-injury that resembles the magical ritual acts of indigenous peoples' use of tattoos. The taboo thus serves as an ersatz for the actual violation of the taboo in real life, so that the tattoo may be ascribed a magical significance or totemic function. And yet the tattoo's success as a vehicle for constructing a transitional object is always contingent on the tangible manipulation of the skin conjoined with the creation of a symbolizing visual image. The image then acts like a "patch" to repair holes blown into Winnicott's "potential space" and to reconstruct it. Copyright © 2011 Institute of Psychoanalysis.

The prevalence of mild adverse reactions, i.e. complaints, in tattoos is sparsely described. The demography of tattoos in a young population representing an index population of the recent trend was studied. The prevalence of complaints related to tattoos, and tattoos by number, size, localization and colour were registered. The data were collected through personal interviews and examinations of consecutive individuals who spontaneously attended a clinic of venereology. Of 154 participants with 342 tattoos, 27% reported complaints in a tattoo beyond 3 months after tattooing. The complaints were predominantly related to black and red pigments. The participants reported complaints in 16% of their tattoos. Fifty-eight per cent of those complaints were sun induced. The complaints varied in intensity but were mainly minor. Skin elevation and itching were most frequent. The responders stated overall satisfaction with 80% of all tattoos. Eight per cent of tattoos were situated on anatomical sites prohibited by Danish law. We found a remarkably high prevalence of tattoo complaints, including photosensitivity, among young individuals tattooed with carbon black and organic pigments especially red. © 2012 The Authors.

The prevalence of tattoos continues to grow as modern society's stigma towards this form of body art shifts towards greater acceptance. Approximately one third of Americans aged 18-25 and 40 % of Americans aged 26-40 are tattooed. As tattoos continue to rise in popularity, so has the demand for an effective method of tattoo removal such as lasers. The various colors of tattoo inks render them ideal targets for specific lasers using the principle of selective photothermolysis. Traditional laser modalities employed for tattoo removal operate on pulse durations in the nanosecond domain. However, this pulse duration range is still too long to effectively break ink into small enough particles. Picosecond (10 -12 ) lasers have emerged at the forefront of laser tattoo removal due to their shorter pulse lengths, leading to quicker heating of the target chromophores, and consequently, more effective tattoo clearance. Recent studies have cited more effective treatment outcomes using picosecond lasers. Future comparative studies between picosecond lasers of various settings are necessary to determine optimal laser parameters for tattoo clearance.

Superficial venous thrombosis (SVT) has been considered for a long time a limited clinical condition with a low importance, but this approach has changed in recent years, when several studies demonstrated spreading to deep veins occurring from 7.3 to 44%, with high prevalence of pulmonary embolism. To evaluate the prevalence of genetic risk factors for VTE in patients suffering from SVT on both normal and varicose vein, and to understand their role on spreading to deep veins, we studied 107 patients with SVT, without other risk factors. Ultrasound examination was performed, and the presence of FV Leiden, Prothrombin G20210A mutation, and MTHFR C677T mutation was researched. In the patients where SVT occurred in normal veins, the presence of FV Leiden was 26.3% of the non-spreading and 60% of the spreading to deep veins SVT; Prothrombin mutation was found in 7.9% of the former case and in 20% of the latter; MTHFR C677T mutation was found respectively in 23.7% and 40%. In the patients with SVT on varicose veins, the presence of these factors was less evident (6.7%, 4.4% and 6.7% respectively), but their prevalence was considerably higher (35.7%, 7.4% and 21.4% respectively) in SVT spreading to deep veins than in non-spreading. Our data demonstrate the high prevalence of these mutations, especially FV Leiden and associations, in patients with SVT on normal veins and their role in the progression to deep vein system.

For many people, getting a tattoo is like purchasing art, and many professional and famous tattooists are artists who are acknowledged by colleagues and authorities. The history of tattooing goes back for thousands of years, and the reasons for getting tattooed are many. These permanent markings are always personal, they can be plain or elaborate, and they serve as amulets, healing and status symbols, declarations of love, signs of religion, adornments and even forms of punishment. Drivers behind the fascination of acquiring a tattoo may fall into four main groups, namely healing, affiliation, art and fashion. © 2015 S. Karger AG, Basel.

Background : More and more people of all age classes have a tattoo. Intriguingly, there are multiple prejudices in the general population and published data that concern tattooed persons, such as being criminals, having a low education, being alcohol or drug abusers, or more risky in their life style. Objective : To obtain and to evaluate sociodemographic data on tattooed persons, to investigate the incidence of tattoo-related cutaneous complications and to define personal risk factors and course of the persons after being tattooed concerning behavior of personal environment. Patients and Methods : We interviewed 426 participants with already existing tattoos and 20 participants just before getting a new tattoo by using an online questionnaire. The participators were asked about socio-epidemiologic aspects of tattoos in general and special aspects of their own tattoo(s) in particular. There were no exclusion criteria. Results : Tattoos are interesting for people seeking popular body art, esp. university graduates and financially-secure individuals. 446 persons participated in this study. Most of the persons were female with a mean age of 35. Local pruritus around the tattooed area was the most common cutaneous side effect among the participants. 93.5% of the participants did not want a tattoo removal. Intriguingly, most of the participants experienced no career problems related to the tattoo(s). Limitations : The study population is not representative as we included only persons being tattooed prior to or getting newly tattooed. Furthermore, there is a potential selection bias as the participation in this study was voluntary. Only persons that felt involved by the flyer did answer the questionnaire. Conclusion : The present data shows that common tattooed persons are not low educated criminals with any drug or alcohol abuse or with risky life style. Nowadays being tattooed encompasses a kind of body art and displays a certain kind of lifestyle habit.

The main objective of this work is to extract the hand vein network using a non-invasive technique in the near-infrared region (NIR). The visualization of the veins is based on a relevant feature of the blood in relation with certain wavelengths of the electromagnetic spectrum. In the present paper, we first introduce the image formation in the NIR spectral band. Then, the acquisition system will be presented as well as the method used for the image processing in order to extract the vein signature. Extractions of this pattern on the finger, on the wrist and on the dorsal hand are achieved after exposing the hand to an optical stimulation by reflection or transmission of light. We present meaningful results of the extracted vein pattern demonstrating the utility of the method for a clinical application like the diagnosis of vein disease, of primitive varicose vein and also for applications in vein biometrics.

Lasers for tattoo removal: a review.

Tattoos have existed and have been used as an expression of art by man for ages-and so have the techniques to remove them. Lasers based on the principle of selective photothermolysis are now being used to remove black as well as colorful tattoos with varying successes. The commonly used lasers for tattoo removal are the Q-switched 694-nm ruby laser, the Q-switched 755-nm alexandrite laser, the 1,064-nm Nd:YAG laser, and the 532-nm Nd:YAG laser. Newer techniques and methods are evolving in tattoo removal with lasers. Choosing the right laser for the right tattoo color is necessary for a successful outcome. Our review aims to understand the principles of laser tattoo removal and their applications for different types and colors of tattoos. The review also highlights the complications that can occur such as dyspigmentation, allergic reactions, epidermal debris, ink darkening, and so on, in this process and how to prevent them.

Novel developments in foam sclerotherapy: Focus on Varithena® (polidocanol endovenous microfoam) in the management of varicose veins.

PubMed

Star, Phoebe; Connor, David E; Parsi, Kurosh

2018-04-01

Scope Varithena® is a recently approved commercially available drug/delivery unit that produces foam using 1% polidocanol for the management of varicose veins. The purpose of this review is to examine the benefits of foam sclerotherapy, features of the ideal foam sclerosant and the strengths and limitations of Varithena® in the context of current foam sclerotherapy practices. Method Electronic databases including PubMed, Medline (Ovid) SP as well as trial registries and product information sheets were searched using the keywords, 'Varithena', 'Varisolve', 'polidocanol endovenous microfoam', 'polidocanol' and/or 'foam sclerotherapy/sclerosant'. Articles published prior to 20 September 2016 were identified. Results Foam sclerosants have effectively replaced liquid agents due to their physiochemical properties resulting in better clinical outcomes. Medical practitioners commonly prepare sclerosant foam at the bedside by agitating liquid sclerosant with a gas such as room air, using techniques as described by Tessari or the double syringe method. Such physician-compounded foams are highly operator dependent producing inconsistent foams of different gas/liquid compositions, bubble size, foam behaviour and varied safety profiles. Varithena® overcomes the variability and inconsistencies of physician-compounded foam. However, Varithena® has limited applications due to its fixed sclerosant type and concentration, cost and lack of worldwide availability. Clinical trials of Varithena® have demonstrated efficacy and safety outcomes equivalent or better than physician-compounded foam but only in comparison to placebo alone. Conclusion Varithena® is a promising step towards the creation of an ideal sclerosant foam. Further assessment in independent randomised controlled clinical trials is required to establish the advantages of Varithena® over and above the current best practice physician-compounded foam.

Paradoxical darkening and removal of pink tattoo ink.

It is widely accepted that Q-switched lasers are the gold-standard treatment for the resolution of unwanted tattoo ink. Although much safer than other tattoo removal modalities, the treatment of tattoo ink with Q-switched devices may be associated with long-term adverse effects including undesired pigmentary alterations such as tattoo ink darkening. Darkening of tattoo ink is most often reported in cosmetic, flesh-toned, white, peach, and pink tattoos. In this paper, we briefly review a case of pink tattoo ink that initially darkened paradoxically but eventually resolved with continued Q-switched laser treatments.

Techniques for tattoo removal have evolved significantly over the years. The commonly used Quality-switched (QS) ruby, alexandrite, and Nd:YAG lasers are the traditional workhorses for tattoo removal. Newer strategies using combination laser treatments, multi-pass treatments, and picosecond lasers offer promising results. The tattoo color and skin type of the patient are important considerations when choosing the appropriate laser. Standard protocols can be developed for the effective and safe treatment of tattoos.

The aim was to investigate the cost-effectiveness of interventional treatment for varicose veins (VV) in the UK NHS, and to inform the national clinical guideline on VV, published by the National Institute of Health and Care Excellence. An economic analysis was constructed to compare the cost-effectiveness of surgery, endothermal ablation (ETA), ultrasound-guided foam sclerotherapy (UGFS), and compression stockings (CS). The analysis was based on a Markov decision model, which was developed in consultation with members of the NICE guideline development group (GDG). The model had a 5-year time horizon, and took the perspective of the UK National Health Service. Clinical inputs were based on a network meta-analysis (NMA), informed by a systematic review of the clinical literature. Outcomes were expressed as costs and quality-adjusted life years (QALYs). All interventional treatments were found to be cost-effective compared with CS at a cost-effectiveness threshold of £20,000 per QALY gained. ETA was found to be the most cost-effective strategy overall, with an incremental cost-effectiveness ratio of £3,161 per QALY gained compared with UGFS. Surgery and CS were dominated by ETA. Interventional treatment for VV is cost-effective in the UK NHS. Specifically, based on current data, ETA is the most cost-effective treatment in people for whom it is suitable. The results of this research were used to inform recommendations within the NICE guideline on VV. Copyright © 2015 European Society for Vascular Surgery. Published by Elsevier Ltd.

Gigantism of the lower limb in Klippel-Trenaunay syndrome: anatomy of the lateral marginal vein.

PubMed

Abdul-Rahman, N R; Mohammad, K F; Ibrahim, S

2009-06-01

The Klippel-Trenaunay syndrome is a combination of venous and capillary malformations associated with soft tissue and/or bony limb hypertrophy, with or without lymphatic malformations. Although persistent foetal veins are rare, the persistence of the lateral marginal vein is a common association in this syndrome. It results in venous hypertension, which gives rise to venous varicosities, which are commonly seen in this syndrome. This is a case report of a 28-year-old man with Klippel-Trenaunay syndrome, with persistence of the lateral marginal vein, affecting his right lower limb. He was treated with an above-knee amputation. The amputated limb was dissected to demonstrate the anatomy of the lateral marginal vein. To the best of the authors' knowledge, the gross anatomy of the lateral marginal vein has not been previously reported.

Lasers are the standard modality for tattoo removal. Though there are various factors that determine the results, we have divided them into three logical headings, laser dependant factors such as type of laser and beam modifications, tattoo dependent factors like size and depth, colour of pigment and lastly host dependent factors, which includes primarily the presence of a robust immune response. Modifications in the existing techniques may help in better clinical outcome with minimal risk of complications. This article provides an insight into some of these techniques along with a detailed account of the factors involved in tattoo removal. PMID:25949018

To determine the natural history of deep vein thrombosis in children presented with a first episode in the lower extremity veins. Children with objective diagnosis of acute deep vein thrombosis were followed up with ultrasound and clinical examination. Risk factors and clinical presentation were prospectively collected. The prevalence of recurrent deep vein thrombosis and the development of signs and symptoms of chronic venous disease were recorded. There were 27 children, 15 males and 12 females, with acute deep vein thrombosis, with a mean age of 4 years, range 0.1-16 years. The median follow-up was 23 months, range 8-62 months. The location of thrombosis involved the iliac and common femoral vein in 18 patients and the femoral and popliteal veins in 9. Only one vein was affected in 7 children, two veins in 14 and more than two veins in 6. Recurrent deep vein thrombosis occurred in two patients, while no patient had a clinically significant pulmonary embolism. Signs and symptoms of chronic venous disease were present at last follow-up in 11 patients. There were nine patients with vein collaterals, but no patient developed varicose veins. Reflux was found in 18 veins of 11 patients. Failure of recanalization was seen in 7 patients and partial recanalization in 11. Iliofemoral thrombosis (p = 0.012) and failure to recanalize (p = 0.036) increased significantly the risk for developing signs and symptoms. Children with acute proximal deep vein thrombosis develop mild chronic venous disease signs and symptoms at mid-term follow-up and are closely related with iliofemoral thrombosis and failure to recanalization. © The Author(s) 2014.

Smooth muscle neurokinin-2 receptors mediate contraction in human saphenous veins.

2011-05-01

Substance P (SP) and neurokinin A (NKA) are members of the tachykinin peptides family. SP causes endothelial-dependant relaxation but the contractile response to tachykinins in human vessels remains unknown. The objective was to assess the expression and the contractile effects of tachykinins and their receptors in human saphenous veins (SV). Tachykinin expression was assessed with RT-PCR, tachykinin receptors expression with RT-PCR and immunohistochemistry, and functional studies were performed in organ bath. Transcripts of all tachykinin and tachykinin receptor genes were found in SV. NK(1)-receptors were localized in both endothelial and smooth muscle layers of undistended SV, whereas they were only found in smooth muscle layers of varicose SV. The expression of NK(2)- and NK(3)-receptors was limited to the smooth muscle in both preparations. NKA induced concentration-dependent contractions in about half the varicose SV. Maximum effect reached 27.6±5.5% of 90 mM KCl and the pD(2) value was 7.3±0.2. NKA also induced the contraction of undistended veins from bypass and did not cause the relaxation of these vessels after precontraction. The NK(2)-receptor antagonist SR48968 abolished the contraction induced by NKA, and a rapid desensitization of the NK(2)-receptor was observed. In varicose SV, the agonists specific to NK(1)- or NK(3)-receptors did not cause either contraction or relaxation. The stimulation of smooth muscle NK(2)-receptors can induce the contraction of human SV. As SV is richly innervated, tachykinins may participate in the regulation of the tone in this portion of the low pressure vascular system. Copyright © 2011 Elsevier Ltd. All rights reserved.

Tattoos can harm perceptions: a study and suggestions.

Health researchers have claimed that perceptions toward a person with a tattoo are more negative than are perceptions toward nontattooed persons. However, support for this has been obtained almost completely by nonexperimental research. In 2 experiments with 158 community college student participants, the authors found that tattoos harmed perceptions. Students viewed a photograph of a female model with and without a visible tattoo, and rated her on 13 personal characteristics. In Experiment 1, ratings of a model with a dragon tattoo were significantly more negative (p < .05) on 5 of the 13 personal characteristics than were ratings of the same model shown without the tattoo. In Experiment 2, which included different participants, a different model, and a different tattoo, the authors found that a dolphin tattoo led to more negative ratings on 2 of the 13 characteristics. The authors discuss possible impacts of tattoos on person perception as well as implications of the results for college student healthcare providers.

Sclerotherapy has wide applicability in treating venous disease at every stage of clinical disease. The various sclerosant drugs and formulations each have unique properties, utilities, and side effects. Treating physicians should be aware of the differences between agents, accounting for disease presentation, vein characteristics, and patient comorbidities when selecting the appropriate sclerosing agents. Successful outcomes rely on proper patient evaluation and assessment for contraindications to sclerotherapy. Thorough patient education regarding realistic expectations with sclerotherapy in terms of symptoms relief, recurrence, and improvement in appearance is of chief importance.

2011-06-01

Tattoo segmentation is challenging due to the complexity and large variance in tattoo structures. We have developed a segmentation algorithm for finding tattoos in an image. Our basic idea is split-merge: split each tattoo image into clusters through a bottom-up process, learn to merge the clusters containing skin and then distinguish tattoo from the other skin via top-down prior in the image itself. Tattoo segmentation with unknown number of clusters is transferred to a figureground segmentation. We have applied our segmentation algorithm on a tattoo dataset and the results have shown that our tattoo segmentation system is efficient and suitable for further tattoo classification and retrieval purpose.

Optodynamic monitoring of laser tattoo removal.

The goal of this research is to use the information contained in the mechanisms occurring during the laser tattoo removal process. We simultaneously employed a laser-beam deflection probe (LBDP) to measure the shock wave and a camera to detect the plasma radiation, both originating from a high-intensity laser-pulse interaction with a tattoo. The experiments were performed in vitro (skin phantoms), ex vivo (marking tattoos on pig skin), and in vivo (professional and amateur decorative tattoos). The LBDP signal includes the information about the energy released during the interaction and indicates textural changes in the skin, which are specific for different skin and tattoo conditions. Using both sensors, we evaluated a measurement of threshold for skin damage and studied the effect of multiple pulses. In vivo results show that a prepulse reduces the interaction strength and that a single strong pulse produces better removal results.

To our knowledge tattooing has never been thought of as a method of introducing nanoparticles (NPs) into the human body by the intradermal route, and as such it has never been a topic of research in nanotoxicology. The content of NPs in tattoo inks is unknown. To classify the particle sizes in tattoo inks in general usage. The particle size was measured by laser diffraction, electron microscopy and X-ray diffraction. The size of the pigments could be divided into three main classes. The black pigments were the smallest, the white pigments the largest and the coloured pigments had a size in between the two. The vast majority of the tested tattoo inks contained significant amounts of NPs except for the white pigments. The black pigments were almost pure NPs, i.e. particles with at least one dimension <100 nm. The finding of NPs in tattoo inks in general usage is new and may contribute to the understanding of tattoo ink kinetics. How the body responds to NP tattoo pigments should be examined further. © 2011 The Authors. BJD © 2011 British Association of Dermatologists.

Though the skin is affected in sarcoidosis in about one-third of cases, granulomatous tattoo reactions are an unusual manifestation of the disease. It is important phenomenon to recognize, as it frequently leads to the diagnosis of systemic sarcoidosis. A 35-year-old Caucasian female with multiple tattoos presented with a 5-week history of tenderness of the black dye in a tattoo depicting a dragon. She also described a 15-month history of fatigue, polyarthralgia, and mild dyspnea. Skin biopsy demonstrated multiple dermal non-caseating granulomata with associated tattoo ink. Further investigation revealed the presence of systemic sarcoidosis. Her symptoms and skin changes improved with conservative management. Sarcoidal tattoo reactions in those without systemic sarcoidosis are a rare occurrence, and their presence should prompt a search for systemic involvement. The accurate identification of skin involvement in sarcoidosis is important, as it tends to occur early in the course of disease, and the skin is a readily accessible site for biopsy, allowing for prompt diagnosis.

Social and familial history shows frequent conflictual, divorced, separated parents; the father is often ill, old or missing. Most family have many children. Low socio-cultural and economical level is common. Forensic and pyschological history is already heavily rich. However tattooing and delinquency cannot be assimilated. As found in many other studies, most of the tattooed did not undergone this type of inquiry. Only particular tattooed are probably investigated, and comparative samples of non-tattooed are lacking most of the time. Tattooing indicate more social and psychological misery of the milieu during childhood of this adolescents than their own pathological problems. It is more sociopathy than psychopathy. The analysis of the tattooed drawings is provided. They are stereotyped and commonplace, and very similar to graffiti. Circumstances at the times of tattooing are described as their present attitude to their tattooing, specially the wish to remove their tattooed figures. Recent literature is reviewed.

Millions of people are tattooed with inks that contain azo pigments. The pigments contained in tattoo inks are manufactured for other uses with no established history of safe use in humans and are injected into the skin at high densities (2.5 mg/cm(2)). Tattoo pigments disseminate after tattooing throughout the human body and although some may photodecompose at the injection site by solar or laser light exposure, the extent of transport or photodecomposition under in vivo conditions remains currently unknown. We investigated the transport and photodecomposition of the widely used tattoo Pigment Red 22 (PR 22) following tattooing into SKH-1 mice. The pigment was extracted quantitatively at different times after tattooing. One day after tattooing, the pigment concentration was 186 microg/cm(2) skin. After 42 days, the amount of PR 22 in the skin has decreased by about 32% of the initial value. Exposure of the tattooed skin, 42 days after tattooing, to laser light reduced the amount of PR 22 by about 51% as compared to skin not exposed to laser light. A part of this reduction is as a result of photodecomposition of PR 22 as shown by the detection of corresponding hazardous aromatic amines. Irradiation with solar radiation simulator for 32 days caused a pigment reduction of about 60% and we again assume pigment decomposition in the skin. This study is the first quantitative estimate of the amount of tattoo pigments transported from the skin into the body or decomposed by solar or laser radiation.

Introduction. Tattoos have increasingly become accepted by mainstream Western society. As a result, the incidence of tattoo-associated dermatoses is on the rise. The presence of a poorly differentiated squamous cell carcinoma in an old tattooed skin is of interest as it has not been previously documented. Case Presentation. A 79-year-old white homeless man of European descent presented to the dermatology clinic with a painless raised nodule on his left forearm arising in a tattooed area. A biopsy of the lesion revealed a poorly differentiated squamous cell carcinoma infiltrating into a tattoo. The lesion was completely excised and the patient remains disease-free one year later. Conclusion. All previous reports of squamous cell carcinomas arising in tattoos have been well-differentiated low-grade type or keratoacanthoma-type and are considered to be coincidental rather than related to any carcinogenic effect of the tattoo pigments. Tattoo-associated poorly differentiated invasive carcinoma appears to be extremely rare. PMID:21274289

With the increasing popularity of tattoo body decorations, reports of medical complications with tattoos have increased in parallel. Although tattoo reactions can resolve spontaneously, they often last for months or even years, despite the various treatment methods. In our case, we present the successful removal of hyperkeratotic-lichenoid reaction to red ink using a simple and cheap skin grafting knife. The entire tattoo was preserved with a good aesthetic result with minimal scarring.

The popularity of tattoos has increased tremendously in the last 10 yr particularly among athletes and military personnel. The tattooing process involves permanently depositing ink under the skin at a similar depth as eccrine sweat glands (3-5 mm). The purpose of this study was to compare the sweat rate and sweat Na concentration of tattooed versus nontattooed skin. The participants were 10 healthy men (age = 21 ± 1 yr), all with a unilateral tattoo covering a circular area at least 5.2 cm. Sweat was stimulated by iontophoresis using agar gel disks impregnated with 0.5% pilocarpine nitrate. The nontattooed skin was located contralateral to the position of the tattooed skin. The disks used to collect sweat were composed of Tygon® tubing wound into a spiral so that the sweat was pulled into the tubing by capillary action. The sweat rate was determined by weighing the disk before and after sweat collection. The sweat Na concentration was determined by flame photometry. The mean sweat rate from tattooed skin was significantly less than nontattooed skin (0.18 ± 0.15 vs 0.35 ± 0.25 mg·cm·min; P = 0.001). All 10 participants generated less sweat from tattooed skin than nontattooed skin and the effect size was -0.79. The mean sweat Na concentration from tattooed skin was significantly higher than nontattooed skin (69.1 ± 28.9 vs 42.6 ± 15.2 mmol·L; P = 0.02). Nine of 10 participants had higher sweat Na concentration from tattooed skin than nontattooed skin, and the effect size was 1.01. Tattooed skin generated less sweat and a higher Na concentration than nontattooed skin when stimulated by pilocarpine iontophoresis.

Multiphoton tomography of intratissue tattoo nanoparticles

Most of today's intratissue tattoo pigments are unknown nanoparticles. So far, there was no real control of their use due to the absence of regulations. Some of the tattoo pigments contain carcinogenic amines e.g. azo pigment Red 22. Nowadays, the European Union starts to control the administration of tattoo pigments. There is an interest to obtain information on the intratissue distribution, their interaction with living cells and the extracellular matrix, and the mechanisms behind laser tattoo removal. Multiphoton tomographs are novel biosafety and imaging tools that can provide such information non-invasively and without further labeling. When using the spectral FLIM module, spatially-resolved emission spectra, excitation spectra, and fluorescence lifetimes can pr provided. Multiphoton tomographs are used by all major cosmetic comapanies to test the biosafety of sunscreen nanoparticles.

Given that the pigment particles in tattoos have a relaxation time of <10 ns, picosecond lasers would be expected to be more effective than nanosecond lasers in tattoo removal. To systematically review the evidence regarding the effectiveness and safety of picosecond lasers for tattoo removal, Pubmed, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, and reference lists were searched for relevant trials. The primary outcome was >70 % clearance of tattoo pigment. Secondary outcomes were 90-100 % clearance of tattoo pigment, number of laser sessions required, and adverse effects. Eight trials were included, six with human participants (160 participants) and 2 with animal models. Seven of the eight trials explored the usage of either 755, 758, 795, 1064, or 1064/532-nm picosecond lasers for black and blue ink tattoos. In the human trials, 69-100 % of tattoos showed over 70 % clearance of pigment after 1-10 laser treatments. Reported side effects included pain, hyperpigmentation and hypopigmentation, blister formation and transient erythema, edema, and pinpoint bleeding. Included articles varied in type of laser investigated, mostly non-comparative studies and with a medium to high risk of bias. There is sparse evidence that picosecond lasers are more effective than their nanosecond counterparts for mainly black and blue ink tattoo removal, with minor side effects.

Endovenous laser ablation (EVLA) has been shown to be effective for the elimination of saphenous veins and associated reflux. Mechanism is known to be heat related, but precise way in which heat causes vein ablation is not completely known. This study aimed to determine the effects of various endovenous laser wavelengths and delivery modes on ex vivo human vein both macroscopically and microscopically. We also evaluated whether protected-tip fibers, consisting of prototype silica fibers with a metal tube over the distal end, reduced vein wall perforations compared with non-protected-tip fibers. An ex vivo EVLA model with human veins harvested during ambulatory phlebectomy procedures was used. Six laser fiber combinations were tested: 810 nm continuous wave (CW) diode laser with a flat tip fiber, 810 CW diode laser with a protected tip fiber, 1,320 nm pulsed Nd:YAG laser, 1,310 nm CW diode laser, 1,470 nm CW diode laser, and 2,100 nm pulsed Ho:YAG laser. Perforation or full thickness necrosis of a portion of the vein wall was observed in 5/11 (45%), 0/11 (0%), 3/22 (14%), 7/11 (64%), 4/6 (67%), and 5/10 (50%) of cross-sections of veins treated with the 810 nm CW diode laser with a flat tip fiber, the 810 CW diode laser with a protected tip fiber, the 1,320 nm pulsed Nd:YAG laser, the 1,310 nm CW diode laser, the 1,470 nm CW diode laser, and the 2,100 nm pulsed Ho:YAG laser, respectively. Our results have shown that the delivery mode, pulsed Nd:YAG versus CW, may be just as important as the wavelength. Therefore, the 1,310 nm CW laser may not be equivalent to the 1,320 nm pulsed laser. In addition, protected 810 nm fibers may be less likely to yield wall perforations than their non-protected counterparts. Copyright © 2012 Wiley Periodicals, Inc.

Early methods of tattoo removal ultimately resulted in unacceptable cosmetic outcomes. While the introduction of laser technology was an improvement over the existing chemical, mechanical, and surgical procedures, the use of nonselective tattoo removal with carbon dioxide and argon lasers led to scarring. Q-switched lasers with nanosecond (10-9) pulse domains were considered to have revolutionized tattoo treatment, by selectively heating the tattoo particles, while reducing the adverse sequelae to adjacent normal skin. Theoretical considerations of restricting pulse duration, to heat tattoo particles to higher temperatures, proposed the use of sub-nanosecond pulses to target particles with thermal relaxation times lower than the nanosecond pulses in Q-switched lasers. Initial studies demonstrated that picosecond (10-12) pulses were more effective than nanosecond pulses in clearing black tattoos. Advances in picosecond technology led to the development of commercially available lasers, incorporating several different wavelengths, to further refine pigment targeting. © 2017 S.

2015-01-01

Summary Tattooing has long been practised in various societies all around the world and is becoming increasingly common and widespread in the West. Tattoo ink suspensions unquestionably contain pigments composed of nanoparticles, i.e., particles of sub-100 nm dimensions. It is widely acknowledged that nanoparticles have higher levels of chemical activity than their larger particle equivalents. However, assessment of the toxicity of tattoo inks has been the subject of little research and ink manufacturers are not obliged to disclose the exact composition of their products. This study examines tattoo ink particles in two fundamental skin components at the nanometre level. We use atomic force microscopy and light microscopy to examine cryosections of tattooed skin, exploring the collagen fibril networks in the dermis that contain ink nanoparticles. Further, we culture fibroblasts in diluted tattoo ink to explore both the immediate impact of ink pigment on cell viability and also to observe the interaction between particles and the cells.

2011-01-01

Amalgam tattoos are common exogenous pigmented lesions of the oral mucosa occurring mainly by inadvertent placement of amalgam particles into soft tissues. The diagnosis of amalgam tattoo is simple, usually based on clinical findings associated with presence or history of amalgam fillings removal. Intraoral X-rays may be helpful in detecting amalgam-related radiopacity. In cases where amalgam tattoo cannot be differentiated from other causes of oral pigmentation, a biopsy should be performed. This article deals with an extensive amalgam tattoo lesion which required a biopsy for a definitive diagnosis.

2013-08-01

To explore the characteristics of military service tattoos a descriptive study was conducted at Walter Reed Army Medical Center to collect information from a convenience sample. An investigator-developed questionnaire provided the data for this study. Over the ensuing 12 month-period the researchers collected 126 questionnaires. Typical respondents were enlisted men with at least one deployment to an area of combat operations. Among the respondents, 57% acquired their tattoos before their deployment. One-quarter of the respondents reported only one tattoo, leaving the majority with multiple tattoos. Men received their first tattoo at an earlier age than women. The most common tattoo listed a person's name. Respondents did not regret their tattoos and rarely acquired the body art under the influence of alcohol or drugs. Little evidence was found to support a connection between tattoos and deployment. Few regretted their decisions and most all approached the tattoo experience free of any mind-altering substance. All this seems to suggest that military tattoos are a well-accepted means of self-expression. Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.

Tattoo-like epidermal sensors are an emerging class of truly wearable electronics, owing to their thinness and softness. While most of them are based on thin metal films, a silicon membrane, or nanoparticle-based printable inks, we report sub-micrometer thick, multimodal electronic tattoo sensors that are made of graphene. The graphene electronic tattoo (GET) is designed as filamentary serpentines and fabricated by a cost- and time-effective "wet transfer, dry patterning" method. It has a total thickness of 463 ± 30 nm, an optical transparency of ∼85%, and a stretchability of more than 40%. The GET can be directly laminated on human skin just like a temporary tattoo and can fully conform to the microscopic morphology of the surface of skin via just van der Waals forces. The open-mesh structure of the GET makes it breathable and its stiffness negligible. A bare GET is able to stay attached to skin for several hours without fracture or delamination. With liquid bandage coverage, a GET may stay functional on the skin for up to several days. As a dry electrode, GET-skin interface impedance is on par with medically used silver/silver-chloride (Ag/AgCl) gel electrodes, while offering superior comfort, mobility, and reliability. GET has been successfully applied to measure electrocardiogram (ECG), electromyogram (EMG), electroencephalogram (EEG), skin temperature, and skin hydration.

The 'sparing phenomenon' of purpuric rash over tattooed skin.

2014-01-01

Cutaneous complications associated with decorative tattooing are well known. However, the inhibition of a purpuric reaction by a tattoo is a fact that, as far as the authors know, has not been described before, fitting the definition of a 'sparing phenomenon', the absence of manifesting a particular skin disease in an area previously affected by another condition. From the clinical observation of purpuric lesions apparently inhibited by a tattoo in a 26-year-old patient, we performed an exact binomial test on the observed and expected proportion of purpuric lesions inside (0%, 95% confidence interval, CI, 0-2.6%) and outside (100%, 95% CI 97.4-100%) the tattooed skin, demonstrating a nonrandom distribution respecting the tattooed area (p < 0.001) and identifying the composition of the ink used in the tattoo (color pigment, glycerine, Hamamelis virginiana extract, water and alcohol). Moreover, we reviewed the cases of sparing phenomenon described in the literature. In conclusion this is the first report of a sparing phenomenon of purpuric lesions over tattooed skin. © 2013 S.

2016-03-01

Currently, the incidence of tattooing is on the rise compared to the past, especially among adolescents, and it leads to the urgency of monitoring the security status of tattooing centers, as well as to inform people about the risks of tattoo practice. In our clinical experience, 20% of tattooed patients presented adverse reactions, like allergic contact dermatitis, psoriasis with Koebner's phenomena and granulomatous reactions, with the latter most prevalent and most often related to red pigment. Adverse reactions to tattoo pigments, especially the red one, are well known and described in literature. Great attention has to be focused on the pigments used, especially for the presence of new substances, often not well known. For this reason, we decided to perform a study on 12 samples of red tattoo ink, obtained by patients affected by different cutaneous reactions in the site of tattoo, to analyze their chemical composition.

The presence of tattoos on the skin of people of all ages is on the rise. On occasion, the tattoo is in close proximity to an area which has to undergo a surgical operation, therefore why not using the tattoo itself to cover the cicatrix? The case we treated was that of a 39 year old female who, for a couple of years, had a large lipoma on her right shoulder which she never treated because it was beneath a large tattoo. During the surgical treatment of the lipoma, we followed the exact lines of the tattoo itself thus obtaining precise access for lipoma removal which minimized visible post operative cicatrix while maintaining the original tattoo design. No similar case was found in literature. PMID:21103075

For millennia, peoples around the world have tattooed human skin to communicate various ontological, psychosocial, and sociocultural concepts encompassing beauty, cultural identity, status and position, medicine, and supernatural protection. As a system of knowledge transmission, tattooing has been and continues to be a visual language of the skin whereby culture is inscribed, experienced, and preserved in a myriad of specific ways. If we are to fully comprehend the meanings that tattoos have carried across human history and into the present, then it would be useful to explore some of the ways tattoos, as instruments that transmit culture, have been deployed cross-culturally through time. © 2015 S.

Picosecond lasers are a novel laser with the ability to create a pulse of less than one nanosecond. They have been available in the clinical context since 2012. Dermatologists are now using picosecond lasers regularly for the treatment of blue and green pigment tattoo removal. This article reviews the use of picosecond lasers beyond tattoo removal. The overall consensus for the use of picosecond lasers beyond tattoo treatment is positive. With examples of this in the treatment of nevus of Ota, minocycline-induced pigmentation, acne scarring, and rhytides.

Individual Risk and Prevention of Complications: Doctors' Advice to Persons Wishing a New Tattoo.

PubMed

Serup, Jørgen

2017-01-01

Doctors who are consulted about health and tattoo risks have an important role in the prevention of an individual's tattoo complications. Tattooing is a tremendous exposure of the human body to needle operation, particles, and chemicals. The risk is related to a person's health condition, level of insight, decision-making, and to the operation of tattooing, tattoo inks and utensils, tattoo parlour, and the aftercare. Tattooing is painful minor surgery performed without anesthesia. It can be associated with syncope. It is major needle trauma with histamine release and wheal and flare in the operation field. The skin barrier is broken. Bacterial infections come early. Chronically intermittent and mild complaints affect 4/10 of all the tattooed, and 2/10 have sensitivity to sun. Chronic complications with allergy in red tattoos and nodules due to pigment agglomeration and foreign body formation in black tattoos are less common but certainly at the level of cumbersome skin disease. Reactions to black tattoos are strongly associated with sarcoidosis. There are many other distinct entities of tattoo complications. A campaign called 'Tattoo - know your risk' is presented with detailed fact sheets about tattoos, tattoo problems, how to reduce risk, and a checklist for the tattoo customer before decision-making. The sheets with keynote information are useful aids for doctors giving advice to persons curious about acquiring a tattoo. © 2017 S. Karger AG, Basel.

The use of blood-type tattoos during the Cold War.

2008-03-01

We have seen a number of individuals who received blood-type tattoos on the left side of the chest as schoolchildren in northwest Indiana during the 1950s. To investigate the history of blood-type tattooing. Historical research was conducted using newspaper and journal articles found in medical libraries, online archives, American Medical Association archives, Chicago Historical Society records, local medical society documents, in addition to personal interviews. Blood-type tattoos were used during the Cold War to enable rapid transfusions as part of a "walking blood bank" in case of atomic attack. Nationwide blood-typing programs occurred to inform individuals of their own blood types and to provide local communities with lists of possible donors. The blood-type tattooing program was part of this effort, but community-wide tattooing occurred only in two parts of the United States: Lake County, Indiana, and Cache and Rich counties, Utah. In these communities, during 1951 and 1952, schoolchildren were tattooed to facilitate emergency transfusions. Events occurred more than 50 years ago, so we relied on original documents and interviews from individuals involved in the program who are still alive. The use of blood-type tattoos was short lived, lasting less than a year, and ultimately failed because physicians did not trust tattoos for medical information.

[Functional status of musculo-venous pump of shin in various types of of operations for varicose disease].

1997-01-01

Functional conditions of the muscular-venous pump of the shin were studied in 280 patients with varicose veins before surgery, in 164 patients in remote terms after various operations and in 54 healthy subjects on the base of guantitative plethysmographic estimation of hemodynamic parameters. At the stage of compensation all volume indices of the bloodflow were close to normal values; in the stage of decompensation the substantial increase of volume effectiveness and volume flow velocity was observed at carrying out the test for direct deep blood flow when walking. It was determined that in natural condition for venous hemodynamics the adaptation mechanisms of musculo-venous pump were not realized. The operation of Linton upsets the function of musculo-venous pump of the shin. The Kocket operation does not eliminate the pathologic overload when working due to insufficient radicalism in liquidation of perforation escape (steal phenomena). The subfascial ligation of perforating veins of the shin through the minor approach, used in clinical practice, proved to be sufficiently radical and does not impair the function of the musculo-venous pump of the shin.

Interactions between risky decisions, impulsiveness and smoking in young tattooed women

PubMed Central

2013-01-01

Background According to previous studies, one of the common problems of everyday life of persons with tattoos is risky behavior. However, direct examination of the decision making process, as well as factors which determine women’s risk-taking decisions to get tattoos, have not been conducted. This study investigates whether risk taking decision-making is associated with the self-assessment impulsiveness in tattooed women. Methods Young women (aged 18–35 years) with (N = 60) and without (N = 60) tattoos, performed the Iowa Gambling Task (IGT), as a measure of decision-making processes, as well as completing the Barratt Impulsivity Scale (BIS-11). Results Tattooed women showed significantly higher scores in the BIS-11 and preference for disadvantageous decks on the IGT compared to non-tattooed women. There was no significant correlation between risky decision-making in the IGT and BIS-11 impulsivity measures. A significantly higher rate of smoking was observed in the tattooed women. However, the analysis did not reveal a group effect after adjustment for smoking in the IGT and the BIS-11 measures. Conclusions The present study was specifically designed to resolve questions regarding associations between impulsiveness and risky decision-making in tattooed women. It shows that in tattooed women, risky decisions are not a direct result of their self-reported impulsiveness. Smoking does not explain the psychometric differences between tattooed women and controls. PMID:24180254

Laser-Tissue Interaction in Tattoo Removal by Q-Switched Lasers

Barua, Shyamanta

2015-01-01

Q-switched (QS) lasers are widely considered the gold standard for tattoo removal, with excellent clinical results, impressive predictability, and a good safety profile. The generation of giant pulses by the method of Q-switching is responsible for the unique laser-tissue interaction that is seen in tattoo removal by QS lasers. The QS lasers work by impaction and dissolution of the tattoo pigments. Mechanical fragmentation of the tattoo pigments encased in intracellular lamellated organelles followed by their phagocytosis by macrophages is thought to be the major event in the clearance of pigments by QS lasers. A few novel techniques have been tried in recent times to hasten the clearance of tattoo pigments. PMID:25949016

2017-01-01

Background and Aims Balloon-assisted enteroscopy (BAE) is a well-established tool in the diagnosis and therapy of small bowel diseases. Ink tattooing of the small bowel is used to mark pathologic lesions or the depth of small bowel insertion. The purpose of this study was to determine the safety, the detection rate, and the clinical relevance of ink tattooing during BAE. Methods We performed a retrospective analysis of all 81 patients who received an ink tattooing during BAE between 2010 and 2015. Results In all patients, ink tattooing was performed with no complications. 26 patients received a capsule endoscopy after BAE. The tattoo could be detected via capsule endoscopy in 19 of these 26 patients. The tattoo of the previous BAE could be detected via opposite BAE in 2 of 11 patients. In 9 patients, ink tattooing influenced the choice of approach for reenteroscopy. In 7 patients, the tattoo was used for intraoperative localization and in 3 patients for intraoperative localization as well as for reenteroscopy. The intraoperative detection rate of the tattoo was 100%. Conclusion Ink tattooing of the small intestine is a safe endoscopic procedure to mark the depth of scope insertion or a pathologic lesion during balloon-assisted enteroscopy. PMID:29230241

Purpose: The purpose of this study was to survey entry-level dental hygiene program directors in the United States (U.S.) to assess their perceptions of dental hygienists with visible tattoos as well as to determine current policies related to dress codes in U.S. dental hygiene programs. Methods: Data was collected with an online survey emailed to 340 dental hygiene program directors yielding a 43% (n=141) response rate. Participants indicated their opinions of visible tattoos on the basis of professionalism and school policy satisfaction. Results: Eighty percent of respondents reported their program as having dress code policies on visible tattoos, with the majority (97%) requiring visible tattoos to be covered. Results revealed both students (M=5.57, p<.0005) and faculty (M=5.76, p<.0005) with visible tattoos were perceived as significantly less professional. Most participants agreed that dental hygiene faculty should discuss the impact of visible tattoos on future employment opportunities, and that the community would view the school as less professional if students had visible tattoos (p<0.0005). Personal tolerance toward tattoos (p< 0.001), but not age, (p = 0.50), was significantly associated with satisfaction concerning program tattoo policies. A lower tolerance towards visible tattoos (p < 0.001) was associated with an increased likelihood that the dental hygiene program dress code included policy on visible tattoos. Conclusion: Study results showed that visible tattoos were not perceived favorably and that personal perceptions of dental hygiene program directors may have influenced school dress code polices regarding visible tattoos. These findings provide evidence based information for dental hygienists, students, faculty, administrators and hiring managers for formulating policies relating to body art.

Currently, precise non-invasive diagnostics systems for the real-time multi detection and monitoring of physiological parameters and chemical analytes in the human body are urgently required by clinicians, physiologists and bio-medical researchers. We have developed a novel cost effective smart 'vanishing tattoo' (similar to temporary child's tattoos) consisting of environmental-sensitive dyes. Painlessly impregnated into the skin the smart tattoo is capable of generating optical/fluorescence changes (absorbance, transmission, reflectance, emission and/or luminescence within UV, VIS or NIR regions) in response to physical or chemical changes. These changes allow the identification of colour pattern changes similar to bar-code scanning. Such a system allows an easy, cheap and robust comprehensive detection of various parameters and analytes in a small volume of sample (e.g. variations in pH, temperature, ionic strength, solvent polarity, presence of redox species, surfactants, oxygen). These smart tattoos have possible applications in monitoring the progress of disease and transcutaneous drug delivery. The potential of this highly innovative diagnostic tool is wide and diverse and can impact on routine clinical diagnostics, general therapeutic management, skin care and cosmetic products testing as well as fundamental physiological investigations.

Neurite varicosities are highly specialized compartments that are involved in neurotransmitter/ neuromodulator release and provide a physiological platform for neural functions. However, it remains unclear how microtubule organization contributes to the form of varicosity. Here, we examine the three-dimensional structure of microtubules in varicosities of a differentiated PC12 neural cell line using ultra-high voltage electron microscope tomography. Three-dimensional imaging showed that a part of the varicosities contained an accumulation of organelles that were separated from parallel microtubule arrays. Further detailed analysis using serial sections and whole-mount tomography revealed microtubules running in a spindle shape of swelling in some other types of varicosities. These electron tomographic results showed that the structural diversity and heterogeneity of microtubule organization supported the form of varicosities, suggesting that a different distribution pattern of microtubules in varicosities is crucial to the regulation of varicosities development.

Tattooing is a procedure where ink is applied to an area of the skin, mostly intraepidermally (1). This procedure is carried out mainly for aesthetic purposes. Lately, it has been used as a corrective medical procedure following amputation of mammilla. The procedure is aggressive (2), and the fact that skin is punctured many times with the same needle which cannot be fully sterilized may cause infection of the treated area with bacterial, fungal, or viral agents that may lead to health consequences manifesting in the form of verrucae vulgaris, molluscum contagiosum, and herpes simplex. On the other hand, complications such as granulomas, allergic reactions, Koebner phenomenon, lupus erythematosus, psoriasis, lichen ruber planus, hepatitis C, and HIV infections should also be considered as potential consequences of tattooing (3-7). Even systemic reactions have been reported. Herein we describe a case of herpes infection activation after tattooing. Herein we present the case of a 46-year-old woman, employed in the medical sector, with a two-day history of herpes simplex in the labial area that manifested following application of a cosmetic tattoo meant to outline the lips (Figure 1). Two days after tattoo application, the vesicular lesions appeared along the area that was filled with ink, followed by sub-febrile temperature and fever and a subjective feeling of itching initially, followed by burning sensation and pain. The skin signs located on erythematous base were mainly grouped vesicles with sharply demarcated borders. Regional lymphatic nodes, mainly retro auricular, were enlarged. Within 48 hours, the patient was treated with acyclovir tablets in a dose of 800 mg three times a day and an antipyretic. Acyclovir ointment was administered during the first two days, as well as tetracycline ointment after the second day of the eruption. On the fifth day, we observed regression of the skin changes (Figure 2), and complete healing was achieved after one week. We

Endovenous ablation has been performed for varicose veins of the limbs in Indonesia since 2010. Endovenous laser ablation (EVLA) therapy has been performed in Cipto Mangunkusumo Hospital (RSCM) in Jakarta, and mechanochemical ablation (MOCA) has been conducted in Fatmawati Hospital. This was a descriptive analytical study, with a cross-sectional design to analyze post-ablation recanalization after MOCA and EVLA procedures. Patients who had undergone MOCA or EVLA treatment were interviewed 3-18 months after the procedures. All the patients underwent vascular ultrasonography (USG) of the operated limb to assess recanalization. Secondary presurgery data were obtained from the patients’ from patients’ medical records. The clinical characteristics of the subjects were recorded to compare the potential correlation between these characteristics and recanalization post-MOCA and EVLA procedures. All the data were analyzed using SPSS ver. 20.0. The study consisted of 43 limbs: 24 treated by MOCA and 19 treated by EVLA. Most subjects in the MOCA group were <60 years (20/24), and 16 of the subjects were women. In the EVLA group, nine patients were <60 years, and 19 were ≥60 years, 15 of whom were women. The body mass index (BMI) of the majority (18/24) of the subjects in the MOCA group was normal, whereas most of the patients in the EVLA (10/19) group were overweight. In the MOCA group, the largest diameter of the vena saphena magna (VSM) in 20/24 extremities prior to treatment was VSM 4-7 mm, whereas the largest diameter in the EVLA group prior to treatment was >7 mm in 13/19 extremities. In the MOCA group, total recanalization occurred in 2/24 extremities, and partial recanalization occurred in 8/24 extremities. In the EVLA group, total recanalization occurred in 1/19 extremities, and partial recanalization occurred in 3/19 extremities. The association between the clinical characteristics of the patients and recanalization was not statistically significant (p > 0

The Amsterdam model for control of tattoo parlours and businesses.

In the early 1980s, an outbreak of hepatitis B in Amsterdam stood at the start of the development of the first hygiene guidelines for tattooists in The Netherlands. Ever since, infection control in tattoo practice has continued to prove its importance as tattoo-related outbreaks of infectious diseases have continued to be reported in Europe. Furthermore, the act of tattooing includes breaking the skin barrier but is performed by professionals who are not medically trained. The Ministry of Health has now implemented uniform regulations that apply to professionals who perform tattooing and apply permanent make-up. These regulations include hygiene guidelines that were developed by the National Institute for Public Health and the Environment in cooperation with representatives of the tattooing associations. The guidelines contain a list of requirements, including for the studio interior, the cleanness of the studio, the safe use of permitted equipment and products, sterilization methods, and the information provided to the customer. A permit may be granted after an inspection by the local health service, during which the act of tattooing has to be performed. It is now estimated that over 95% of all tattoos in The Netherlands were obtained at one of the almost 900 licensed studios. Reports of complications are generally low in number. We suggest that uniform European hygiene guidelines would further contribute to the safety of tattooing. © 2015 S. Karger AG, Basel.

Bioanalytical evidence that chemicals in tattoo ink can induce adaptive stress responses.

PubMed

Neale, Peta A; Stalter, Daniel; Tang, Janet Y M; Escher, Beate I

2015-10-15

Tattooing is becoming increasingly popular, particularly amongst young people. However, tattoo inks contain a complex mixture of chemical impurities that may pose a long-term risk for human health. As a first step towards the risk assessment of these complex mixtures we propose to assess the toxicological hazard potential of tattoo ink chemicals with cell-based bioassays. Targeted modes of toxic action and cellular endpoints included cytotoxicity, genotoxicity and adaptive stress response pathways. The studied tattoo inks, which were extracted with hexane as a proxy for the bioavailable fraction, caused effects in all bioassays, with the red and yellow tattoo inks having the greatest response, particularly inducing genotoxicity and oxidative stress response endpoints. Chemical analysis revealed the presence of polycyclic aromatic hydrocarbons in the tested black tattoo ink at concentrations twice the recommended level. The detected polycyclic aromatic hydrocarbons only explained 0.06% of the oxidative stress response of the black tattoo ink, thus the majority of the effect was caused by unidentified components. The study indicates that currently available tattoo inks contain components that induce adaptive stress response pathways, but to evaluate the risk to human health further work is required to understand the toxicokinetics of tattoo ink chemicals in the body.

This article presents the fabrication and characterization of novel tattoo-based solid-contact ion-selective electrodes (ISEs) for non-invasive potentiometric monitoring of epidermal pH levels. The new fabrication approach combines commercially available temporary transfer tattoo paper with conventional screen printing and solid-contact polymer ISE methodologies. The resulting tattoo-based potentiometric sensors exhibit rapid and sensitive response to a wide range of pH changes with no carry-over effects. Furthermore, the tattoo ISE sensors endure repetitive mechanical deformation, which is a key requirement of wearable and epidermal sensors. The flexible and conformal nature of the tattoo sensors enable them to be mounted on nearly any exposed skin surface for real-time pH monitoring of the human perspiration, as illustrated from the response during a strenuous physical activity. The resulting tattoo-based ISE sensors offer considerable promise as wearable potentiometric sensors suitable for diverse applications.

Unattractive, promiscuous and heavy drinkers: perceptions of women with tattoos.

This study examined social and physical perceptions of blonde and brunette women with different degrees of tattooing. Eighty-four female and 76 male undergraduates rated a series of 16 female line drawings that varied in 2 levels of hair colour and 8 levels of tattooing. Ratings were made for physical attractiveness and sexual promiscuity, as well as estimates of the number of alcohol units consumed on a typical night out. Results showed that tattooed women were rated as less physically attractive, more sexually promiscuous and heavier drinkers than untattooed women, with more negative ratings with increasing number of tattoos. There were also weak interactions between body art and hair colour, with blonde women in general rated more negatively than brunettes. Results are discussed in terms of stereotypes about women who have tattoos and the effects of such stereotypes on well-being.

Physical therapists (PTs) frequently provide neuromusculoskeletal treatment for patients who incidentally may have one or more tattoos. Low level light therapy (LLLT) is one of the modalities commonly used by physical therapists to decrease pain and facilitate healing. This case report describes a 22 year old man who was given LLLT to address his complaints of musculoskeletal pain. Blistering of the skin was documented over the LLLT application site, a black tattoo. The blisters, which formed after the LLLT treatment were most likely caused by the inadvertent and unexpected heating of the iron oxides and/or the metal salts in the tattoo's black pigment. PTs should exercise caution when applying LLLT in the presence of dark tattoos. Copyright © 2016 Elsevier Ltd. All rights reserved.

The use of tattoos and piercings has increased, especially among adolescents in the last decades. To evaluate the prevalence of these behaviors in adolescents and their association with risk behaviors such as alcohol, tobacco and illicit drug use and sexual promiscuity. An anonymous and confidential survey about tattooing and piercings was applied to randomly selected high school teenagers, attending municipal, private-subsidized and private schools, in four sectors of Santiago (north-east, south-east, north-west, south-west). The surveys were answered by 1329 participants with a mean age of 15 years (62% women) from 9 schools in Santiago. The prevalence of tattoos was 1.7% (confidence intervals (CI) 1.1% to 2.5%). The figure for piercings was 30.6% (CI 28.2 to 33.1%). A higher prevalence of tattooing and piercings was observed in groups with a history of psychiatric disorders, criminal records, alcohol, tobacco and illicit drug consumption and initiation of sexual activity (p < 0,001). This study confirms that tattoos and piercings are indicators of adolescent risk behaviors.

Chi, Y-W; Woods, T C

2014-04-01

Endovenous laser ablation of saphenous veins is an alternative in treating symptomatic varicose veins. Deep venous thrombosis (DVT) has been reported in up to 7.7% of patients undergoing such procedure. We sought to establish clinical risk factors that predict DVT post-endovenous laser ablation. Patients who underwent endovenous laser ablation were prospectively followed. Clinical data and post-interventional duplex ultrasound were analysed. A P value <0.05 was accepted as representing a significant difference. From 2007 to 2008, 360 consecutive patients were followed. Nineteen DVTs were found on follow-up ultrasound. Eighteen cases involved either the saphenofemoral or saphenopopliteal junctions; only one case involved the deep venous system. Age >66 (P = 0.007), female gender (P = 0.048) and prior history of superficial thrombophlebitis (SVT) (P = 0.002) were associated with increased risk of DVT postprocedure. Age >66, female gender and history of SVT were significant predictors of DVT post-endovenous laser ablation of saphenous veins.

A Prospective Study in Comparison of Ambulatory Phlebectomy and Duplex Guided Foam Sclerotherapy in the Management of Varicosities with Isolated Perforator Incompetence.

Perforators are those which connect the superficial and deep venous system either directly to main veins or indirectly through the muscular and soleal venous plexus. The emergence of minimally invasive techniques like ambulatory phlebectomy (AP) and foam sclerotherapy (FS) has led to increasing interest about the appropriate therapy for the treatment of isolated perforator incompetence. There have been no studies which have compared the effectiveness of these in-office procedures in isolated perforator incompetence due to the low prevalence of cases. The primary goal of this study is to compare the clinical parameters (return to normal activity, primary symptom relief), functional parameters (procedure time, change in disease severity, course of venous ulcer), and duplex parameters (recurrence in treated veins, complete occlusion of treated veins) in the management of leg varicosities having isolated primary perforator incompetence by ambulatory phlebectomy and duplex guided foam sclerotherapy. Though the procedure time was shorter with FS than AP, the other parameters of primary symptom relief such as change in disease severity, faster healing of venous ulcer, complete occlusion of treated veins in follow-up duplex examination, and lower recurrence of treated veins are better with AP than FS. In conclusion, the interruption of perforators is effective in decreasing the symptoms of chronic venous insufficiency and for the rapid healing of ulcers. The interruption of the incompetent perforating veins appears to be essential to decrease ambulatory venous hypertension. It is apparent from this study that ambulatory phlebectomy stands distinct with enormous benefits and serves as a superior alternative to foam sclerotherapy in treating patients with isolated perforator incompetence.

A tattoo is defined as the intentional or accidental deposit of pigment into the skin. The phenomenon of skin tattooing is on the rise worldwide and complications of tattooing are increasingly being recognised in diagnostic and clinical medicine. We describe a case of calcification-like changes on mammography resembling that of breast malignancy as a result of tattoo pigment deposition in an axillary lymph node. Recognition of such changes in routine breast screening is crucial to avoid further unnecessary invasive investigations and surgery in such patients. PMID:23929611

Oliver, William R; Leone, Lisa

2012-07-01

The presence and location of tattoos can be an important component in the identification of remains in the extended postmortem period if remnants of skin persist. However, when there is significant mummification, visualization of tattoos can be problematic. Multiple methods have been proposed to make tattoos more visible, but all have limitation. In this case report, a mummified body was discovered. The presumptive victim was reported to have a small tattoo on her hand but it was not visible to the naked eye. The hand was photographed using ultraviolet (UV) and infrared (IR) light. A tattoo matching the description was noted in the photographs. In contrast to film-based IR and UV photography, digital UV and IR photography allows rapid visual evaluation of results and optimization of image utility. The ability to quickly modify photographic parameters quickly greatly increases the utility of IR and UV photography in the autopsy suite. © 2012 American Academy of Forensic Sciences.

The bleaching of polyacrylamide tattooed skin-mimicking phantoms by a series of laser pulses in a single session is studied. It is shown that compared to the single-pulse procedures tattoo removal by series of laser pulses allows not only for reducing the necessary laser fluence, but also for improving the degree of bleaching. The dynamics of formation and dissolution of microscopic gas bubbles in tattooed skin phantoms exposed to laser radiation is also studied. A laser-induced tattoo bleaching mechanism is suggested, based on the process of selective photo-thermolysis of pigmented particles in conditions where the thermal conductivity of the medium surrounding the particles is decreased because of the microbubbles formed therein.

The aim of this study was to analyze digestive hemorrhage by oesophageal varicose vein bleeding, were pharmacological and endoscopic treatments suitable are not available. This prospective study related to 50 patients admitted for oesophageal varicose vein bleeding in the service of hepato-gastro-enterology of the hospital Gabriel Touré (MALI), from June 2003 to December 2005. The patients underwent clinical examination and upper digestive endoscopy to appreciate oesophageal varicose vein and marks of bleeding. Some biological examinations (haemoglobin, hematocrit, prothrombin time) were carried out in emergency to appreciate systemic repercussion of the haemorrhage. Our results showed that by oesophageal varicose vein bleeding represented 2.5% of the hospitalizations during the period of study.The average age of the patients was 37 years with, a sex ratio of 6.1% in favour of men. Antecedent of jaundice was frequently found (54%). The main cause of the varicose vein was cirrhosis. Mortality was 48%. The prognosis was not significantly improved by blood transfusion. At the end of this study, the stress must be laid on the HBV prevention because HBV is the main cause of chronic liver diseases.

Immune cells play an important role during the generation and resolution of thrombosis. T cells are powerful regulators of immune and nonimmune cell function, however, their role in sterile inflammation in venous thrombosis has not been systematically examined. This study investigated the recruitment, activation, and inflammatory activity of T cells in deep vein thrombosis and its consequences for venous thrombus resolution. CD4 + and CD8 + T cells infiltrate the thrombus and vein wall rapidly on deep vein thrombosis induction and remain in the tissue throughout the thrombus resolution. In the vein wall, recruited T cells largely consist of effector-memory T (T EM ) cells. Using T-cell receptor transgenic reporter mice, we demonstrate that deep vein thrombosis-recruited T EM receive an immediate antigen-independent activation and produce IFN-γ (interferon) in situ. Mapping inflammatory conditions in the thrombotic vein, we identify a set of deep vein thrombosis upregulated cytokines and chemokines that synergize to induce antigen-independent IFN-γ production in CD4 + and CD8 + T EM cells. Reducing the number of T EM cells through a depletion recovery procedure, we show that intravenous T EM activation determines neutrophil and monocyte recruitment and delays thrombus neovascularization and resolution. Examining T-cell recruitment in human venous stasis, we show that superficial varicose veins preferentially contain activated memory T cells. T EM orchestrate the inflammatory response in venous thrombosis affecting thrombus resolution. © 2016 American Heart Association, Inc.

Varicose veins afflict some 10 to 20% of the population in the west. It is believed to be less prevalent in the developing nations. Though there are absolute indications of surgery for varicose veins, people in Nepal come for treatment of the varicose veins either to join the army or to work abroad. Not all hospitals in Nepal are equipped with a vein stripper. In KMCTH, we studied 29 patients who had their long Saphenous veins stripped either with a stripper or by tunnelling around the Saphenous vein. We found that the long Saphenous vein could be stripped via the tunnelling method with an additional incision above the knee joint which is cosmetically accepted by our patients Moreover the patients were much satisfied because of minimal or no bruises in the post operative period as compared to those who had the long Saphenous vein stripped with a stripper.

Millions of people are tattooed. However, the frequency of health problems is unknown. We performed an Internet survey in German-speaking countries. The provenance of tattooed participants (n = 3,411) was evenly distributed in Germany. The participants had many (28%; >4) and large tattoos (36%; >or=900 cm(2)). After tattooing, the people described skin problems (67.5%) or systemic reactions (6.6%). Four weeks after tattooing, 9% still had health problems. Six percent reported persistent health problems due to the tattoo, of which females (7.3%) were more frequently concerned than males (4.2%). Colored tattoos provoked more short-term skin (p = 0.003) or systemic (p = 0.0001) reactions than black tattoos. Also the size of tattoos and the age at the time of tattooing play a significant role in many health problems. Our results show that millions of people in the Western world supposedly have transient or persisting health problems after tattooing. Owing to the large number and size of the tattoos, tattooists inject several grams of tattoo colorants into the skin, which partly spread in the human body and stay for a lifetime. The latter might cause additional health problems in the long term. Copyright 2010 S. Karger AG, Basel.

Body piercing and tattooing are accepted by a growing number of teenagers and young adults as a way of self-expressing. Some authors suggest association between body piercings/tattoos and early sexual initiation, higher number of sexual partners, or risky sexual behaviors. The aim of the study was to evaluate sexual behaviors among young adults with body modifications (BMs)--tattoos and piercings. One hundred twenty young healthy adults, ages between 20 and 35, were included in the population study. The study group was divided into three subgroups: controls (N = 60), adults with tattoos (N = 28), and adults with piercings (N = 32). The research instrument was a self-prepared questionnaire containing 59 questions assessing socioepidemiological parameters, sexual behaviors, incidents of sexual harassment in the past, and self-attractiveness evaluation, as well as questions concerning tattoos and piercings. Socioepidemiological variables and sexual behaviors were compared between subgroups. To assess and describe the correlation between having BM--tattoos and piercing--and sexual behaviors in the population of young adults by using the logistic regression model. Adults with BMs have had their first intercourse statistically earlier and were more sexually active compared with controls. There were no statically significant differences in sexual orientation, sexual preferences, engaging in risky sexual behaviors, frequency of masturbation, and history of sexual abuse between the groups. In contrast, the frequency of sexual intercourses was statistically higher and oral sex was more likely to be a dominant sexual activity in adults with BM compared with controls. The multivariate logistic model revealed that adults with BM were four times less likely to participate in religious practices and twice more likely to have early sexual initiation. Having BM is associated with early sexual initiation and more liberal attitudes toward sexual behaviors but not with engaging in

We previously reported 3-month and 12-month occlusion rates after treatment of clinically symptomatic saphenous vein reflux with either cyanoacrylate closure (CAC) using the VenaSeal Closure System (Medtronic, Dublin, Ireland) or radiofrequency ablation (RFA) in a randomized, multicenter, clinical trial, VenaSeal Sapheon Closure System vs Radiofrequency Ablation for Incompetent Great Saphenous Veins (VeClose). Herein we report the 24-month follow-up results of the VeClose trial. There were 222 patients with symptomatic great saphenous vein (GSV) incompetence who were randomly assigned to receive either CAC (n = 108) or RFA (n = 114). Patients were not allowed to receive adjunctive treatment of tributary varicosities until after the 3-month visit. Duplex ultrasound of the target vein was performed at day 3 and months 1, 3, 6, 12, and 24 after treatment, and closure was assessed by ultrasound by the treating physician. Overall 24-month success rates were compared; in addition, time to first reopening of the target vein was evaluated using survival analysis. End points such as Venous Clinical Severity Score, EuroQoL-5 Dimension, and Aberdeen Varicose Vein Questionnaire were evaluated. Of 222 randomized patients, 171 completed the 24-month follow-up, which included 87 from the CAC group and 84 from the RFA group. The 24-month complete closure rate was 95.3% in the CAC group and 94.0% in the RFA group, demonstrating continued noninferiority of CAC compared with RFA (P = .0034). Symptoms and quality of life improved similarly in both groups. No clinically significant device- or procedure-related late adverse events occurred. Both CAC and RFA were effective in closure of the target GSV, resulting in similar and significant improvements in the patient's quality of life through 24 months. These results suggest that CAC of the GSV is safe and durable out to 2 years. Copyright © 2018 The Authors. Published by Elsevier Inc. All rights reserved.

It is a report on the group activities carried out with carriers of varicose ulcer in a health unit in Porto Alegre, Rio Grande do Sul, Brazil. The varicose ulcer presents factors, besides the biological ones, which interfere in the cicatrization, in the relapse cases and in its effective resolution. The proposed activities aimed at producing behavior changes with the intention of achieving self-care, providing information, socializing the participants, and stimulating cooperation, searching for joint solutions, aggregating interdisciplinary spirit and improving the care. Two groups have been formed and a thematic schedule established. The results have showed higher adhesion to the treatment, behavioral changes, and adapted and more effective attitudes of the health team.

Making innovative tattoo ink products with improved safety: possible and impossible ingredients in practical usage.

PubMed

Dirks, Michael

2015-01-01

Today's tattoo inks are no longer just simple solids in liquid suspension. Nowadays, these inks are high-tech dispersions made from finely spread pigments in a binder-solvent mixture. These so-called colour dispersions must follow the modern standards of tattooing, which are increasing every year. They must be rich in chromophoric pigments and yet fluid, they must not dry rapidly, and there should be no occurrence of any sedimentation, even during longer tattoo seasons. An innovative tattoo ink should enable long-lasting, brilliant tattoos without a negative impact on the artist's workflow and of course without endangering the consumer. The high standard in tattoos, regarding the motives and techniques, that is witnessed today could not be achieved by the artists without quality tools and modern tattoo ink. This article will give the reader a brief overview of the different ingredients of tattoo ink and of the function of binding agents and solvents in modern tattoo ink as well as describe what additives are used to achieve the desired behaviour during application. Furthermore, the article will take a look into the pigments that are used in tattoo ink and show why certain pigments are not suited for tattoo ink. The differences, advantages and disadvantages of organic and inorganic pigments will be explained. © 2015 S. Karger AG, Basel.

Tattoo ink stock products often contain potential carcinogens, which on large-scale population exposure may be clinically relevant. The aim of this autopsy study in mice was to screen major organs for clinical and subclinical cancers. Mice were tattooed on their backs. In total, 48 mice were included and divided into 4 groups; 11 mice tattooed black, 10 tattooed red, and 5 mice serving as untreated controls. A group of 22 mice with black tattoos and exposed to ultraviolet radiation (UVR) were also studied. The black and red inks were both stock products banned on the Danish market due to the measured contents of potential carcinogens; benzo(a)pyrene and 2-anisidine, respectively. The mice were housed for 1 year after tattooing, and autopsy study on internal organs was performed. Tissue samples were systematically taken from major organs for screening of subclinical changes, not detected by visual examination. Any observed deviation from normal structure was subject to biopsy and light microscopy. All mice survived the 1-year observation period. Autopsy revealed no macroscopic signs of cancer. Microscopic search of internal organs showed no subclinical or clinical cancer. Despite extensive tattoos with 2 banned inks, the long-term observation in mice showed no internal cancers nor was the combination of carcinogen and UVR associated with cancer. Lack of observed malignancy might be explained by the fact that tattooing is only a single dose exposure. Registered data on carcinogens relies on repeated or chronic exposures. The study does not support the hypothesis that tattooing causes cancer. © 2017 S. Karger AG, Basel.

To investigate the effects of venous diseases at different anatomical localizations on the qualities of life of patients with varicose veins. The study included 354 cases, which was referred to a private vascular and interventional radiology center in Bursa, Turkey between January 2005 to January 2006. The cases were diagnosed with visual inspection and were clinically indicative of varicose veins. Color Doppler ultrasonography was used to radiologically examine the varicose veins. All cases were accepted as class II criteria according to the Clinical, Etiologic, Anatomic, Pathophysiologic classification. The generic Short Form Health Survey-36 (SF-36) was used to measure physical and mental quality of life (QOL). High scores indicated good QOL. The Statistical Package for Social Sciences version 13.0 program was used for the statistical evaluation. When the life SF-36 quality parameters of cases with different anatomical localizations of the varicose veins were examined, only the mental health scores were found to differ in different groups (p<0.01). In females and males with superficial venous disease, significant differences were found in physical function, physical role and pain among the physical health scale components, and in vitality and emotional role scores among the mental state determinants. When females and males with deep vein disease were compared, significant differences were found among both physical and mental health determinants. Anatomical localization of lower extremity varicose veins can be accepted as a predictive factor in determining the life qualities of patients with varicosities in their lower limb, and should be used to regulate their therapy and follow up protocols.

Causes and Recommendations for Unanticipated Ink Retention Following Tattoo Removal Treatment

PubMed Central

Chen, Cynthia L.; Desai, Alpesh; Desai, Tejas

2013-01-01

While placement of ink into the skin is a long-standing tradition, patients are now seeking tattoo removal on a more frequent basis. Once considered acceptable removal options, tattoo ink removal via physical destruction included dermabrasion, chemical destruction, salabrasion, thermal destruction, and cryotherapy. Now these options are used extremely infrequently. These modalities provided unpredictable results and often required prolonged healing times and left patients with skin discoloration, pain, scarring, and ink retention. Even the widely adopted use of lasers, now considered the gold standard method, offers some level of unpredictability surrounding the natural progression of ink resolution. Multiple factors need to be taken into consideration when successfully removing tattoo pigment including the modalities used, number and frequency of treatments, proper device technique, and physiological barriers to tattoo removal. This paper serves to elucidate the common causes of ink retention following tattoo removal treatment with recommendations on how best to address this relatively common occurrence. PMID:23882312

Towards the limiting of health risks associated with tattooing: whitelists for tattoo pigments and preservatives.

Blume, Annegret; Platzek, Thomas; Vieth, Bärbel; Hutzler, Christoph; Luch, Andreas

2015-01-01

The number of pigments that could potentially be used in tattoo inks is vast. However, pigments are generally not manufactured for the purpose of being injected into subepidermal layers of the skin. Assuming 100% bioavailability after injection means that pigments can be imminently hazardous to human health. Given the ever-increasing number of pigments being circulated on the market or through the internet, a 'negative list' ('black' list) containing pigments with known adverse effects will never be finalised. If incriminated, substances could easily be replaced by structurally similar pigments that might be even more deleterious to human health. Therefore, we and others suggest the establishment of a whitelist ('positive list') that would only contain pigments that had undergone a risk assessment specifically for their application into the dermis. Some of the problems associated with such a 'positive list' are discussed. Another important issue with regard to tattoo safety is related to the preservatives used in ink preparations. Notwithstanding the demand for sterile tattoo inks, a whitelist for these compounds would be beneficial. At present, many technical preservatives are being used, despite their known detrimental effects to human health. Criteria for the inclusion of preservatives in a 'positive list' are also discussed. © 2015 S. Karger AG, Basel.

Sclerotherapy with post-treatment graduated compression remains the criterion standard for treating lower leg telangiectatic, reticular, and varicose veins, but the optimal duration for that postsclerotherapy compression is unknown. To determine whether 3 weeks of additional graduated compression with Class I compression stockings (20-30 mmHg) improves efficacy when used immediately after 1 week of Class II (30-40 mmHg) graduated compression stockings. Twenty-nine patients with reticular or telangiectatic leg veins were treated with sclerotherapy; one leg was assigned to wear Class II compression stocking for 1 week only, and the contralateral leg was assigned an additional 3 weeks of Class I graduated compression stocking. Postsclerotherapy pigmentation and bruising was significantly less with the addition of 3 weeks of Class I graduated compression stockings.

Effects of a tattoo on men's behavior and attitudes towards women: An experimental field study.

Guéguen, Nicolas

2013-11-01

Previous studies have indicated negative evaluations of women with tattoos. However, a study by Swami and Furnham (2007) showed that tattooed women were rated as less physically attractive but more sexually promiscuous. Given that men interpret women's sexual intent according to their physical appearance, we predicted that women with tattoos would be more favorably approached by men. A temporary tattoo was placed on confederates' lower back, or not, and all confederates were instructed to read a book while lying flat on their stomach on a well-known beach. Two experiments were conducted. The first experiment showed that more men (N = 220) approached the tattooed confederates and that the mean latency of their approach was quicker. A second experiment showed that men (N = 440) estimated to have more chances to have a date and to have sex on the first date with tattooed confederates. However, the level of physical attractiveness attributed to the confederate was not influenced by the tattoo condition. These results were discussed with respect to men's possible misinterpretation of women wearing tattoos and the risks associated with this misinterpretation.

Data concerning the effect of the target vein's diameter on efficacy of radiofrequency obliteration (RFO) in the current literature are limited. To assess efficacy of RFO and stripping, peculiarities of the postoperative period course with due regard for the diameter of the target veins, to compare the outcomes of RFO and classical phlebectomy in treatment of varicose disease during 1-year follow up by a composite end point. A multicenter prospective non-randomized study based on analysing therapeutic outcomes in a total of 218 patients presenting with varicose disease (C2-C3 according to the CEAP). RFO was performed in 108 patients and phlebectomy in 110 subjects. The results were assessed by means of a composite end point including four components: technical outcome at 1-year follow-up, pain, subcutaneous haemorrhage, and paresthesias. The groups of patients who endured RFO and phlebectomy were subdivided into two subgroups according to the target vein's diameter with a border of 14 mm. Statistical analysis. We used the methods of non-parametric statistics (contingency tables, chi squared test), calculating the odds ratio (OR) for a favourable outcome with a 95% confidential interval. Pain dynamics was assessed by means of intellectual data analysis (cluster analysis). «Phelbectomy ≥ 14 mm» and «RFO ≥ 14 mm». The incidence rate of a good outcome in the subgroups amounted to 20 (30.8%) and 61 (95.3%), respectively. The odds ratio for favourable outcome between the subgroups of RFA and phlebectomy amounted to 45.8; 95% CI (44.5-47.0). "RFA ≥ 14 mm" and "RFA < 14 mm". Favourable outcome rate in the subgroups amounted to 25 (39.1%) and 17 (38.6%), respectively. The differences were not statistically significant, p=0.24. The odds ratio for a good outcome between the RFO subgroups amounted to: OR=0.98; 95% CI (0.18-1.77). Comparative analysis of RFO outcomes between the clinics. Favourable outcome rate in the first clinic was 50 (92.6%), in the second 34 (87

Pulsed photothermal depth profiling of tattoos undergoing laser removal treatment

Pulsed photothermal radiometry (PPTR) allows noninvasive determination of temperature depth profiles induced by pulsed laser irradiation of strongly scattering biological tissues and organs, including human skin. In present study, we evaluate the potential of this technique for investigational characterization and possibly quantitative evaluation of laser tattoo removal. The study involved 5 healthy volunteers (3 males, 2 females), age 20-30 years, undergoing tattoo removal treatment using a Q-switched Nd:YAG laser. There were four measurement and treatment sessions in total, separated by 2-3 months. Prior to each treatment, PPTR measurements were performed on several tattoo sites and one nearby healthy site in each patient, using a 5 ms Nd:YAG laser at low radiant exposure values and a dedicated radiometric setup. The laser-induced temperature profiles were then reconstructed by applying a custom numerical code. In addition, each tatoo site was documented with a digital camera and measured with a custom colorimetric system (in tristimulus color space), providing an objective evaluation of the therapeutic efficacy to be correlated with our PPTR results. The results show that the laser-induced temperature profile in untreated tattoos is invariably located at a subsurface depth of 300 μm. In tattoo sites that responded well to laser therapy, a significant drop of the temperature peak was observed in the profiles obtained from PPTR record. In several sites that appeared less responsive, as evidenced by colorimetric data, a progressive shift of the temperature profile deeper into the dermis was observed over the course of consecutive laser treatments, indicating that the laser tattoo removal was efficient.

Background: Increased enthusiasm toward newer fashion trends among rural India along with the lack of government regulation has led to increased tattoo reactions. Objective: The objective of this study is to describe various clinical manifestations of hypersensitive reactions to tattoo ink reported at a tertiary care hospital in Mandya district. Materials and Methods: An observational study was carried out over a period of 1 year from June 2014 to May 2015 at Mandya Institute of Medical Sciences, Mandya. All the patients reporting with allergic reaction due to tattooing were included in the present study after obtaining informed consent. Transient acute inflammatory reaction, infections, and skin diseases localized on tattooed area were excluded from this study. A detailed history regarding the onset, duration and color used for tattooing were collected. Cutaneous examination and biopsy was to done to know the type of reaction. Results: Fifty cutaneous allergic reactions were diagnosed among 39 patients. Mean age of subjects was 22 years and mean duration before the appearance of lesion was 7 months. Common colors associated with reactions were red (53.9%), black (33.3%), green (5.1%), and multicolor (7.7%). Itching was the predominant symptom. Skin lesions mainly consisted of lichenoid papules and plaques, eczematous lesions, and verrucous lesions. Lichenoid histopathology reaction was the most common tissue allergic reaction. Conclusion: Increasing popularity of tattooing among young people has predisposed to parallel increase in adverse reactions. Red pigment is most common cause of allergic reaction in the present study, and lichenoid reaction is the most common reaction. PMID:28584372

Cost-effectiveness analysis: role and implications.

PubMed

Marsden, G; Wonderling, D

2013-03-01

Cost-effectiveness analysis (CEA) is often misperceived to be a cost-cutting exercise. The intention of CEA is not to identify and implement cheap technologies, but rather those which offer maximum health gain, subject to available funds. Such analysis is crucial for decision making in health care, as tight budget constraints mean spending in one area of healthcare displaces spending elsewhere. Therefore in order to achieve the greatest health gain for the overall population, treatments must be selected which provide the greatest health gain within the available funds. The relevance of CEA in health care systems is explained, using varicose vein treatment in the UK NHS as an example. Treatment for varicose veins is often not commissioned to at a local level, most likely because it is misperceived to be a cosmetic problem. However, this view does not take into account the impact of quality of life. CEA balances costs against a quantitative measure of health related quality of life, and could therefore be used to determine whether it is cost-effective to provide varicose vein treatment. The current literature on the cost-effectiveness of varicose vein treatment is reviewed, and an overview of cost-effectiveness principles is provided. Concepts such as economic modelling, incremental cost-effectiveness ratios (ICERs), net monetary benefit (NMB) and sensitivity analysis are explained, using examples relevant to varicose veins where appropriate. This article explains how, far from cutting costs and sacrificing patient health, CEA provides a useful tool to maximise the health of the population in the face of ever tightening budget constraints. CEA could be used to compare the cost-effectiveness of the various treatment options for varicose veins, and efficiencies realised.

Seamless prevention of adverse events from tattooing: integrated strategy emphasising the customer-tattooist interaction.

PubMed

Serup, Jørgen

2015-01-01

The boom in tattooing has been paralleled by more frequent adverse events, which may be localised in the skin or systemic and manifested clinically or latent. Infections, allergic reactions from red-coloured tattoos and papulo-nodular reactions from black tattoos dominate. Mild complaints are very common, with 1/5 of all tattooed individuals having acquired sensitivity to sunlight in the tattooed skin. The potential risk of cancer due to potential carcinogens in some tattoo inks has hitherto not manifested in clinical reports, despite the millions of people who have been tattooed over many decades. A risk of death from tattooing remains associated with severe infection, i.e. sepsis. Preventive strategies may rely on focused preventions, and sterility and preservation of ink is essential, rational and knowledge-based. The chemical and particle contents of ink nanoparticles cannot be unrestricted; however, focused control of ink is facing many uncertainties, including analytical problems, lack of identification of allergens in ink and discrepancies between the content of potential carcinogens and manifestation of cancer in the clinic. The concept of seamless prevention is introduced as a pragmatic strategy that emphasises the customer-tattooist interaction, which is the 'engine' of tattoo safety. This strategy amalgamates the range of narrow-scope preventive instruments and shall ensure that any relevant instrument is used actively and without deficiency or drop out, thus resulting in a complete orchestration of a multi-targeted strategy. High-priority elements of this strategy shall facilitate a qualified 'go' or 'no go' decision by the customer before the tattoo is made and should involve informed consent, qualification of the tattooist and the parlour, including supplies of inks etc., and attention to hygienic security.

Objective: The purpose of this UK study was to evaluate interfraction reproducibility and body image score when using ultraviolet (UV) tattoos (not visible in ambient lighting) for external references during breast/chest wall radiotherapy and compare with conventional dark ink. Methods: In this non-blinded, single-centre, parallel group, randomized control trial, patients were allocated to receive either conventional dark ink or UV ink tattoos using computer-generated random blocks. Participant assignment was not masked. Systematic (∑) and random (σ) setup errors were determined using electronic portal images. Body image questionnaires were completed at pre-treatment, 1 month and 6 months to determine the impact of tattoo type on body image. The primary end point was to determine that UV tattoo random error (σsetup) was no less accurate than with conventional dark ink tattoos, i.e. <2.8 mm. Results: 46 patients were randomized to receive conventional dark or UV ink tattoos. 45 patients completed treatment (UV: n = 23, dark: n = 22). σsetup for the UV tattoo group was <2.8 mm in the u and v directions (p = 0.001 and p = 0.009, respectively). A larger proportion of patients reported improvement in body image score in the UV tattoo group compared with the dark ink group at 1 month [56% (13/23) vs 14% (3/22), respectively] and 6 months [52% (11/21) vs 38% (8/21), respectively]. Conclusion: UV tattoos were associated with interfraction setup reproducibility comparable with conventional dark ink. Patients reported a more favourable change in body image score up to 6 months following treatment. Advances in knowledge: This study is the first to evaluate UV tattoo external references in a randomized control trial. PMID:27710100

Tattoos as a window to the psyche: How talking about skin art can inform psychiatric practice.

2017-09-22

Tattooing the skin as a means of personal expression is a ritualized practice that has been around for centuries across many different cultures. Accordingly, the symbolic meaning of tattoos has evolved over time and is highly individualized, from both the internal perspective of the wearer and the external perspective of an observer. Within modern Western societies through the 1970s, tattoos represented a cultural taboo, typically associated with those outside of the mainstream such as soldiers, incarcerated criminals, gang members, and others belonging to marginalized and counter-cultural groups. This paper aims to review the more recent epidemiology of tattoos in Western culture in order to establish that tattooing has become a mainstream phenomenon. We then review psychological and psychiatric aspects of tattoos, with a goal of revising outmoded stigmas about tattooing and helping clinicians working with tattooed patients to facilitate an exploration of the personal meaning of skin art and self-identity. We suggest that as a kind of augmentation of the physical exam, looking at and talking to patients about their tattoos can provide a valuable window into the psyche, informing clinical practice.

Laser tattoo removal is an effective method of eliminating tattoo particles in the skin. However, laser treatment cannot always remove the unwanted tattoo completely, and there are risks of either temporary or permanent side effects. Studies using preclinical animal models could provide detailed information on the effects of laser treatment in the skin, and might help to minimize side effects in clinical practices. In this study, two-photon microscopy (TPM) was used to visualize the laser treatment effects on tattoo particles in both phantom specimens and in vivo mouse models. Fluorescent tattoo ink was used for particle visualization by TPM, and nanosecond (ns) and picosecond (ps) lasers at 532 nm were used for treatment. In phantom specimens, TPM characterized the fragmentation of individual tattoo particles by tracking them before and after the laser treatment. These changes were confirmed by field emission scanning electron microscopy (FE-SEM). TPM was used to measure the treatment efficiency of the two lasers at different laser fluences. In the mouse model, TPM visualized clusters of tattoo particles in the skin and detected their fragmentation after the laser treatment. Longitudinal TPM imaging observed the migration of cells containing tattoo particles after the laser treatment. These results show that TPM may be useful for the assessment of laser tattoo removal treatment in preclinical studies. PMID:28856046

2017-04-01

Purpose Cyanoacrylate closure of the great saphenous vein with the VenaSeal™ Closure System is a relatively new modality. Studies have been limited to moderate-sized great saphenous veins and some have mandated postoperative compression stockings. We report the results of a prospective study of cyanoacrylate closure for the treatment of great saphenous vein, small saphenous veins, and/or accessory saphenous veins up to 20 mm in diameter. Methods Fifty subjects with symptomatic great saphenous vein, small saphenous veins, and/or accessory saphenous veins incompetence were each treated at a single session. Compression stockings were not used post-procedure. Subjects returned to clinic at week 1 and again at one month. Post-procedure evaluations were performed at seven days and one month and included numerical pain rating score, revised venous clinical severity score, the Aberdeen Varicose Vein Questionnaire score, and time to return to work and normal activities. Duplex ultrasound was performed at each visit. Findings Procedural pain was mild (numerical pain rating scale 2.2 ± 1.8). All treated veins (48 great saphenous vein, 14 accessory saphenous veins, and 8 small saphenous veins) had complete closure by duplex ultrasound at seven days and one month. Mean time to return to work and normal activities was 0.2 ± 1.1 and 2.4 ± 4.1 days, respectively. The revised venous clinical severity score was improved to 1.8 ± 1.4 ( p < .001) and Aberdeen Varicose Vein Questionnaire score to 8.9 ± 6.6 ( p < .001) at one month. Phlebitis in the treatment area or side branches occurred in 10 subjects (20%) and completely resolved in all but one subject (2%) by one month; 98% of subjects were "completely" or "somewhat" satisfied, and 2% "unsatisfied" with the procedure at one month, despite the protocol disallowance of concomitant side branch treatment. Conclusions Cyanoacrylate closure is safe and effective for the treatment of one or more

The purpose of the study was to test the hypothesis on participation of WBCs in damaging the venous wall in patients presenting with primary forms of lower limb chronic venous diseases LLCVD . The study included a total of fifteen consecutively selected patients (13 women and 2 men) diagnosed as having grade C2-C-4 LLCVD according to the CEAP classification. Static loading (30 minutes in the sitting position) was followed by simultaneous sampling of blood from the varicose vein of the cms and ulnar vein. The total blood count including determination of both the absolute values and percentage of blood formed elements was performed using the automated haematological counter «Advia 7» («Bayer», USA). The obtained findings were statistically processed using the Microsoft Office Excel software by means of the pared two-sample τ-test for the average values. The number of leukocytes and their subpopulations in blood samples obtained from the crural varicose veins turned out to be significantly less as compared with that in blood sampled from the ulnar vein. Thus, blood sampled from the crural varicose veins demonstrated a decrease in the counts of WBC by 9.6% in fourteen (93.3%) patients, that of neutrophils by 4.9% in twelve (80%) patients, that of lymphocytes by 16,8% in fifteen (100%) patients, and that oi monocytes by 24% in twelve (80%) patients. The mentioned differences were statistically significant at a = 0.05. The eosinophilic counts in blood sampled from the upper and lower extremities appeared similar in 66.7% of the examined subjects. In 33.3% of cases the eosinophilic count in blood samples from crural varicose vein was by 16.7% lower than that for blood samples form the ulnar vein. No differences for the rest parameters of the clinical blood count were revealed. The absolute lymphocytic count in the blood samples taken after the 30-minute static loading from the crural varicose veins was significantly lower as compared with that in blood sampled form

Traditional Samoan tattoos, or tatau, are created by master tattooists, or tufuga ta tatau, and their assistants using multi-pointed handmade tools. These tools are used to tap tattoo pigment into the skin, usually over several days. This traditional process is considered an honor to the one receiving the tatau. Unfortunately, as it is typically practiced according to cultural traditions, the sanitary practices are less than ideal. There have been several reported cases of severe infection, sepsis, shock, and even death as a result of traditional Samoan tattoos. Although Hawai'i is the home of the second largest Samoan population in the United States, short of only American Samoa, literature review found no published case reports in this state. Presented is a case of a 46-year-old man, who, after undergoing a modified version of traditional Samoan tattooing for 5 days, was admitted to the intensive care unit with severe septic shock due to poly-microbial bacteremia with Group A Streptococcus and Methicillin-sensitive Staphylococcus Aureus. In addition, we will discuss the previously reported cases, mainly documented in New Zealand, and review some of the mandatory sanitary standards put into place there. PMID:23386988

A 31-year-old woman who had undergone surgery for a congenital cataract as a newborn developed bilateral malignant glaucoma, which was refractory to medical-surgical treatment. The patient currently has terminal glaucoma and severe band keratopathy. For aesthetic purposes, we performed intrastromal keratopigmentation surgery using ink for skin tattoos supplied in sterile single-dose vessels. No secondary effects or complications were observed. Keratopigmentation or corneal tattooing can now be used as a last resort in patients who are unable to tolerate cosmetic contact or intraocular lenses, or in whom corneal transplant is contraindicated.

Latreille, J; Levy, J-L; Guinot, C

2011-02-01

Despite increasing demands for decorative tattooing in people of all ages, occupations and social classes, little is known regarding individuals' characteristics and behaviour with respect to tattooing. The objective was to describe a large sample of French people asking for tattoo laser removal, to investigate their reasons for being tattooed and for tattoo removal, and to identify groups of subjects sharing similar characteristics. A prospective exploratory study was conducted on 151 consecutive subjects asking for tattoo removal. The study population was composed of 65 women and 86 men, aged between 18 and 60 years. The reasons mentioned for tattoo removal included aesthetic, social, employment, family or partner pressure, change of lifestyle or partner and incompatibility with present attitudes and values. Four profiles were identified. Types 1 and 3 correspond to subjects with amateur tattoos more frequently reporting social reasons for tattoo removal, whereas types 2 and 4 correspond to subjects with studio tattoos who more frequently report aesthetic reasons. Types 1 and 4 are mainly composed of men (aged over forty and under forty, respectively), type 2 of women under thirty and type 3 of subjects of either sex aged over forty. These profiles could be used to target information campaigns about tattooing and tattoo removal techniques to avoid unwanted tattoos, and afterwards, possible disappointment after removal, as well as to target education programs on possible health risks. Furthermore, our findings open the way to focus further studies on more homogenous group of tattooed subjects. © 2010 The Authors.

Laser therapy is the treatment of choice in tattoo removal. However, the precise mechanisms of laser-tattoo pigment interactions remain to be evaluated. We evaluated the geometric patterns of laser-tattoo pigment particle interactions using a tattoo pigment-embedded tissue-mimicking (TM) phantom. A Q-switched (QS) neodymium-doped yttrium aluminum garnet laser was used at settings of 532-, 660-, and 1064-nm wavelengths, single-pulse and quick pulse-to-pulse treatment modes, and spot sizes of 4 and 7 mm. Most of the laser-tattoo interactions in the experimental conditions formed cocoon-shaped or oval photothermal and photoacoustic injury zones, which contained fragmented tattoo particles in various sizes depending on the conditions. In addition, a long-pulsed 755-nm alexandrite laser was used at a spot size of 6 mm and pulse widths of 3, 5, and 10 ms. The finer granular pattern of tattoo destruction was observed in TM phantoms treated with 3- and 5-ms pulse durations compared to those treated with a 10-ms pulse. We outlined various patterns of laser-tattoo pigment interactions in a tattoo-embedded TM phantom to predict macroscopic tattoo and surrounding tissue reactions after laser treatment for tattoo removal. © 2016 John Wiley & Sons A/S.

2018-07-15

Bottlenose dolphins are excellent bioindicators of ocean ecosystem health for three reasons: (a) as long-lived apex predators they accumulate biotoxins and contaminants; (b) they are visible, routinely appearing at the water's surface in coastal areas, often coming into close contact with humans; and, (c) they exhibit a range of pathogenic lesions attributable to environmental degradation. In this study, we analyzed tattoo-like skin lesions in a population of Tursiops aduncus studied for 30+years in Shark Bay, Australia, a UNESCO World Heritage Site. We provide important baseline data by documenting epidemiological patterns of tattoo-like skin lesions in a healthy, free-ranging population that builds on the previous data of tattoo skin disease (TSD) derived from free ranging, stranded, and dead dolphins. Individual dolphins were classified as symptomatic with tattoo-like skin disease if at least one photograph showed a lesion similar to TSD. The average age of infection was 26.6months (±34.8months) with the symptomatic period lasting 137±29.8days. Overall prevalence of tattoo-like skin disease in the population was 19.4%. Age, but not sex, was significant, with yearlings (1-2years) exhibiting tattoo-like lesions more than younger and older calves. Tattoo-like lesions were rare among juvenile and adult dolphins (N=68 calves, 4 juveniles, and 3 adults). We hypothesize that the lower prevalence in youngest calves (<1year) is due to maternal immunity, while older individuals (>2years) have infection-acquired immunity, as reported for other small cetaceans. The low prevalence of tattoo-like lesions in Shark Bay compared to other populations with poxvirus is consistent with reproductive and demographic viability analyses. Furthermore, by documenting the demography of the disease, we can monitor changes in the prevalence of tattoo-like lesions as a sentinel indicator of ecosystem health. Copyright © 2018 Elsevier B.V.

In January 2012, on the basis of an initial report from a dermatologist, we began to investigate an outbreak of tattoo-associated Mycobacterium chelonae skin and soft-tissue infections in Rochester, New York. The main goals were to identify the extent, cause, and form of transmission of the outbreak and to prevent further cases of infection. We analyzed data from structured interviews with the patients, histopathological testing of skin-biopsy specimens, acid-fast bacilli smears, and microbial cultures and antimicrobial susceptibility testing. We also performed DNA sequencing, pulsed-field gel electrophoresis (PFGE), cultures of the ink and ingredients used in the preparation and packaging of the ink, assessment of source water and faucets at tattoo parlors, and investigation of the ink manufacturer. Between October and December 2011, a persistent, raised, erythematous rash in the tattoo area developed in 19 persons (13 men and 6 women) within 3 weeks after they received a tattoo from a single artist who used premixed gray ink; the highest occurrence of tattooing and rash onset was in November (accounting for 15 and 12 patients, respectively). The average age of the patients was 35 years (range, 18 to 48). Skin-biopsy specimens, obtained from 17 patients, showed abnormalities in all 17, with M. chelonae isolated from 14 and confirmed by means of DNA sequencing. PFGE analysis showed indistinguishable patterns in 11 clinical isolates and one of three unopened bottles of premixed ink. Eighteen of the 19 patients were treated with appropriate antibiotics, and their condition improved. The premixed ink was the common source of infection in this outbreak. These findings led to a recall by the manufacturer.

The aim of this study was to prenatally predict placenta accreta in posterior placenta previa using magnetic resonance imaging (MRI). This retrospective study was approved by the Institutional Review Board of our hospital. We identified 81 patients with singleton pregnancy who had undergone cesarean section due to posterior placenta previa at our hospital between January 2012 and December 2016. We calculated the sensitivity and specificity of several well-known findings, and of cervical varicosities quantified using magnetic resonance imaging, in predicting placenta accreta in posterior placenta previa. To quantify cervical varicosities, we calculated the A/B ratio, where "A" was the minimum distance from the most dorsal cervical varicosity to the deciduous placenta, and "B" was the minimum distance from the most dorsal cervical varicosity to the amniotic placenta. The appropriate cut-off value of the A/B ratio was determined using a receiver operating characteristic (ROC) curve. Three patients (3.7%) were diagnosed as having placenta accreta. The sensitivity and specificity of the well-known findings were 0 and 97.4%, respectively. Furthermore, the A/B ratio ranged from 0.02 to 0.79. ROC curve analysis revealed that the area under the combined placenta accreta and A/B ratio curve was 0.96. When the cutoff value of the A/B ratio was set 0.18, the sensitivity and specificity were 100 and 91%, respectively. It was difficult to diagnose placenta accreta in the posterior placenta previa using the well-known findings. The quantification of cervical varicosities could effectively predict placenta accreta.

2015-01-01

In response to two isolated cases of Mycobacterium chelonae infections in tattoo recipients where tap water was used to dilute ink, the New York City (NYC) Department of Health and Mental Hygiene conducted an investigation using Emergency Department (ED) syndromic surveillance to assess whether an outbreak was occuring. ED visits with chief complaints containing the key word “tattoo” from November 1, 2012 to March 18, 2013 were selected for study. NYC laboratories were also contacted and asked to report skin or soft tissue cultures in tattoo recipients that were positive for non-tuberculosis mycobacterial infection (NTM). Thirty-one TREDV were identified and 14 (45%) were interviewed to determine if a NTM was the cause for the visit. One ED visit met the case definition and was referred to a dermatologist. This individual was negative for NTM. No tattoo-associated NTM cases were reported by NYC laboratories. ED syndromic surveillance was utilized to investigate a non-reportable condition for which no other data source existed. The results were reassuring that an outbreak of NTM in tattoo recipients was not occurring. In response to concerns about potential NTM infections, the department sent a letter to all licensed tattoo artists advising them not to dilute tattoo ink with tap water. PMID:26076006

Invagination stripping of the long and short saphenous vein using the PIN stripper.

PubMed

Conrad, P; Gassner, P

1996-06-01

The technique of invagination stripping (IS) of the long saphenous vein (LSV) and short saphenous vein (SSV) using the PIN stripper (PS) is described. One hundred consecutive legs with long saphenous incompetence have been treated with IS of the LSV from the groin to just below the knee using the PS. In 28 of these legs associated short saphenous incompetence was treated with IS of the SSV from the popliteal fossa to just below half-way in the calf. It was found that technically the PS is easy to use. It passes from the groin to just below the knee in the LSV without difficulty. The blunt, slightly bent tip manoeuvres past tributaries and valves with ease. Similarly, the PS passes easily down the SSV to a point just past half-way down the calf. The exit of the stripper tip is much easier than with conventional strippers; there is less tissue trauma and a smaller scar. Inversion stripping is associated with much less tissue trauma, bruising and postoperative pain, and earlier mobilization. The technique appears to have eliminated trauma to the saphenous and sural nerves. This technique will facilitate the use of "day only surgery' for varicose veins and can be performed under femoral nerve block and local anaesthesia.

To determine interrelationship between lower limb varicosity, the clinical grade of non-differentiated dysplasia of the connective tissue and atrial fibrillation in patients with coronary artery disease (CAD). Altogether 156 coronary patients were examined. Persistent atrial fibrillation was present in 58 and chronic in 38 patients. The reference group comprised 60 patients without evident rhythm disorders in persons suffering from CAD. Markers of connective tissue dysplasia () were revealed on the part of the skeleton, joints skin and visceral organs. Lower limb varicosity was recorded as well. The number of the stigmas in the study groups was different. So, in the patient group without rhythm disorders, the mean number of the stigmas was equal to 3, which is a variant of normal. In the groups with persistent and constant AF, this indicator was equal to 4.7 and 5.2 respectively (p<0.05). The number of patients with evident signs of CID (the number of stigmas 5) was greater in the groups with AP than among patients with normal rhythm. Varicosity was recorded in 41% of both group patients. It is to be noted that in the group with normal rhythm, lower limb varicosity was encountered in 22.1% of cases whereas in the group with AF, in 58.4% of cases with persistent AF and in 41% of cases with constant AF. The mean number of stigmas in the group without varicosity accounted for 3.6 and in patients with varicosity - for 5 (P<0.05). When coronary artery disease is coupled with atrial fibrilation there is a direct close correlation between the signs of connective tissue dysplasia and lower limb varicosity. In patients with persistent AF lower limb varicosity occurs more frequently than in CAD patients with normal rhythm.

Self-esteem, propensity for sensation seeking, and risk behaviour among adults with tattoos and piercings

PubMed Central

Hong, Bo-Kyung; Lee, Hyo Young

2017-01-01

Background: In recent years, increasing numbers of adults and adolescents have opted to undergo tattoo and piercing procedures. Studies among adolescents with tattoo and piercing have usually explored the relationship between one factor and the decision to have tattoos and/or piercings. The aim of this study was to determine relationships between body cosmetic procedures and selfesteem, propensity for sensation seeking, and risk behaviours among adults. Materials and Methods: The subjects were divided into two groups, i.e., those with (n=429) and those without tattoos/piercings (n=237), and self-esteem, propensity for sensation seeking, and risk behaviour were compared between the two groups using self-report questionnaires. To analyse differences in self-esteem and the propensity for sensation seeking, general characteristics were statistically adjusted. In addition, general characteristics, self-esteem, and propensity for sensation seeking were statistically adjusted to determine differences in the propensity for risk behaviour between the two groups. Results: Significant differences were observed in age, marital status, income level, occupation, values or sensitivity to fashion, and educational level between the group with and that without tattoos/ piercings. There was no significant difference in self-esteem, whereas there were significant differences in the propensity for sensation seeking and risk behaviour between the two groups. Conclusions: Continuous attention to, and interest in, the increased incidence of tattooing and piercing are necessary, especially in terms of public interventions for health education and health promotion, as these forms of self-adornment are associated with behaviours that pose a risk to health. Significance for public health The age range and occupations of people who undergo tattoo procedures have diversified with their increasing popularity as cosmetic procedures. This study investigated general characteristics of adults with

VATS intraoperative tattooing to facilitate solitary pulmonary nodule resection.

2008-03-19

Video-assisted thoracic surgery (VATS) has become routine and widely accepted for the removal of solitary pulmonary nodules of unknown etiology. Thoracosopic techniques continue to evolve with better instruments, robotic applications, and increased patient acceptance and awareness. Several techniques have been described to localize peripheral pulmonary nodules, including pre-operative CT-guided tattooing with methylene blue, CT scan guided spiral/hook wire placement, and transthoracic ultrasound. As pulmonary surgeons well know, the lung and visceral pleura may appear featureless on top of a pulmonary nodule. This paper presents a rapid, direct and inexpensive approach to peripheral lung lesion resection by marking the lung parenchyma on top of the nodule using direct methylene blue injection. In two patients with peripherally located lung nodules (n = 3) scheduled for VATS, we used direct methylene blue injection for intraoperative localization of the pulmonary nodule. Our technique was the following: After finger palpation of the lung, a spinal 25 gauge needle was inserted through an existing port and 0.1 ml of methylene blue was used to tattoo the pleura perpendicular to the localized nodule. The methylene blue tattoo immediately marks the lung surface over the nodule. The surgeon avoids repeated finger palpation, while lining up stapler, graspers and camera, because of the visible tattoo. Our technique eliminates regrasping and repalpating the lung once again to identify a non marked lesion. Three lung nodules were resected in two patients. Once each lesion was palpated it was marked, and the area was resected with security of accurate localization. All lung nodules were resected in totality with normal lung parenchymal margins. Our technique added about one minute to the operative time. The two patients were discharged home on the second postoperative day, with no morbidity. VATS with intraoperative tattooing is a safe, easy, and accurate technique to

In July 2013, the National Institute of Health and Clinical Excellence (NICE) recommended "endothermal" ablation (meaning endovenous thermal ablation) is the first line treatment for truncal venous reflux in varicose veins. The initial endovenous thermoablation devices were radiofrequency ablation and endovenous laser ablation. More recently, Glue (cyanoacrylate), endovenous steam and Clarivein (mechanochemical ablation or MOCA) have entered the market as new endovenous techniques for the treatment of varicose veins. Glue and Clarivein do not require tumescent anaesthesia and do not use heat and therefore termed non-tumescent non-thermal (NTNT). Steam both requires tumescence and is also a thermal technique (TT). This article reviews the current position of these 3 new technologies in the treatment of varicose veins. © The Author(s) 2015.

Lasers in tattoo and pigmentation control: role of the PicoSure(®) laser system.

2016-01-01

The use of picosecond lasers to remove tattoos has greatly improved due to the long-standing outcomes of nanosecond lasers, both clinically and histologically. The first aesthetic picosecond laser available for this use was the PicoSure(®) laser system (755/532 nm). Now that a vast amount of research on its use has been conducted, we performed a comprehensive review of the literature to validate the continued application of the PicoSure(®) laser system for tattoo removal. A PubMed search was conducted using the term "picosecond" combined with "laser", "dermatology", and "laser tattoo removal". A total of 13 articles were identified, and ten of these met the inclusion criteria for this review. The majority of studies showed that picosecond lasers are an effective and safe treatment mode for the removal of tattoo pigments. Several studies also indicated potential novel applications of picosecond lasers in the removal of various tattoo pigments (eg, black, red, and yellow). Adverse effects were generally mild, such as transient hypopigmentation or blister formation, and were rarely more serious, such as scarring and/or textural change. Advancements in laser technologies and their application in cutaneous medicine have revolutionized the field of laser surgery. Computational modeling provides evidence that the optimal pulse durations for tattoo ink removal are in the picosecond domain. It is recommended that the PicoSure(®) laser system continue to be used for safe and effective tattoo removal, including for red and yellow pigments.

Conventional tattoo removal consists of single-pass treatments, spaced 7-8 weeks apart, for a total of 7-10 sessions. A major limiting factor of this procedure is the development of cavitation bubbles and vacuoles within the epidermis and dermis that result from the rapid heating of tattoo particles by the laser. While multiple-pass methods using the R20 protocol or the PFD patch enhance tattoo removal through epidermal clearance, they have no effect on deep-intradermal pigment associated vacuoles that arise from treatment with lasers such as the Q-switched laser. A 28-year-old female with Fitzpatrick skin Type V presented for treatment of a 6-year-old professional black tattoo on the left ventral wrist. She underwent three treatment sessions at 6-8 week intervals using a commercial 1,064-nm picosecond Nd:YAG laser (PicoWay; Candela, Wayland, MA) and a perfluorodecalin (PFD) patch (Merz; Raleigh, NC). At each treatment session, she received two passes with 1,064-nm, 4-mm spot size, a fluence ranging from 2.8 to 3.2 J/cm 2 and a laser repetition rate of 2 Hz. Between laser passes and following the final laser pass, the medial portion of the tattoo was treated with acoustic shock wave therapy (ASWT) using the Zwave device (Zimmer Medizin Systems; Irvine, CA) with 90 mJ, 22 Hz, and 1,200 pulses. After three treatment sessions, there was 80% clearance of the medial portion of the tattoo that received the ASWT compared with 60% clearance of the lateral portion of the tattoo that was treated with the picosecond 1,064-nm Nd:YAG laser and PFD patch alone. In the days following each treatment session, the patient noted consistently less edema, erythema and epidermal crusting on the portion of the tattoo that received the ASWT. We report a case of 80% tattoo clearance with ASWT in a patient with Fitzpatrick type V skin compared with 60% clearance with the picosecond 1064-nm Nd:YAG laser and PFD patch alone. The concurrent use of the PFD patch, which facilitated multi

Traumatic tattoos are undesirable tattoos caused by different foreign bodies such as fireworks' particles, sand, metals, glass, gunpowder, asphalt, dust, or petroleum products embedded forcefully in the dermis. We report the case of a 54-year-old man who presented with sand and asphalt tattooing on his face following a bomb explosion 15 years ago. Q-switched Nd:YAG laser at a wavelength of 1064 nm with a spot size of 4 mm and a fluence of 7.96 J/cm(2) were applied to treat the patient. The patient tolerated the treatment very well. Most of the blue dots became whitened immediately after the procedure and remained almost clear after a 6-month follow-up.

To report a case of retinal vasculitis occurring after the placement of permanent tattoos. A 21-year-old male was referred to our department with impairment of visual acuity. Permanent tattoos covered the head, body, arms and legs. The patient was examined with ophthalmoscopy, fluorescein angiography, indocyanine green angiography and optical coherence tomography. Systemic medical and laboratory work-up were performed in order to exclude an infectious agent or an inflammatory disease. He had no history of intravenous drug abuse. Our patient presented severe posterior uveitis associated with retinal vasculitis and cystoid macular edema. Laboratory tests ruled out all diseases causing vasculitis. HIV and B, C hepatitis tests were negative. Cystoid macular edema and vasculitis were resolved after immunosuppressive therapy. This is the first description of a retinal vasculitis associated with cystoid macular edema in a completely healthy individual after the placement of permanent tattoos. A phagocytosis of tattoo pigments leading to their lysis is described in the literature as a mechanism causing vasculitis.

Q-switched nanosecond lasers demonstrated their efficacy in treating most types of tattoos, but complete disappearance is not always achieved even after performing numerous laser sessions. Picosecond lasers are supposed to be more efficient in clearing tattoos than nanosecond lasers, but prospective comparative data remain limited. To compare on different types of tattoos the efficacy of a nanosecond laser with two types of picosecond lasers. We conducted a prospective randomized study performed from December 2014 to June 2016 on adult patients with all types of tattoos. The tattoos were divided into two halves of equal size. After randomization, half of the tattoo was treated with a picosecond laser and the other half with a nanosecond laser. The evaluation was performed on standardized pictures performed before treatment and 2 months after the last session, by two physicians, not involved in the treatment, blinded on the type of treatments received. The main end point was a clearance above 75% of the tattoos. A total of 49 patients were included. Professional tattoos represented 85.7%, permanent make-up 8.2% and non-professional tattoo 6.1%. The majority were black or blue and 10.2% were polychromatic. No patient was lost during follow-up. A reduction of 75% or more of the colour intensity was obtained for 33% of the tattoos treated with the picosecond lasers compared to 14% with the nanosecond laser (P = 0.008). An improvement superior to 75% was obtained in 34% monochromic black or blue tattoos with the picosecond lasers compared to 9% for the nanosecond laser. Only one of the five polychromic tattoos achieved more than 75% of improvement with the two types of laser. Our results show a statistically significant superiority of the picosecond lasers compared to the nanosecond laser for tattoo clearance. However, they do not show better efficacy for polychromic tattoos and the difference in terms of side-effects was also minimal with a tendency of picosecond

To investigate the incidence, significance and symbolism of tattooing in Switzerland, a representative group of 2177 young males (all liable for military service, age 19-21 years) were examined in 1988. All tattoos were sketched, the location was recorded and the individual meaning was discussed with the bearer. 135 subjects (6.2%) had 1-9 tattoos per person, showing 155 different marks. Only 13% of all tattoos were professional, moderate to large in size and most often located in the area of the upper arm and the shoulder. 87% of tattoos were self-inflicted or placed by a friend and the left side was therefore preferred (66%). In general, these were small to moderate in size, simple in design, and usually located on the forearm and the hand. The dominant significance of all tattoos was related to mental attitude (29%) and love affairs (14%). 13% were pictorial. Some were related to drug abuse, criminality of gangs, or contained magic symbolism or personal data such as zodiac signs and initials (about 4% each). Only 20% had no conventional or private meaning or involved concealed symbolism. For further understanding of the individuals' social history, it should be noted that some tattoos were characterized by minor differences of meaning, such as the "man-in-4-walls" mark (= prison), the "fuck-the-police" mark, the leaf of cannabis sativa or different cross motifs. Even greater consistency related to tattoos located in the web space between the thumb and the forefinger or on the back of the fingers. The location in itself may therefore provide additional personal information on individual circumstances at the time of tattooing.

Objectives Transforming growth factor-beta1 (TGF-β1) may participate in local chronic inflammatory processes in varicose veins and in venous wall structure modifications through regulation of matrix metalloproteinases (MMP) and their inhibitors (tissue inhibitor of metalloproteinase (TIMP)). The aim of this study was to analyze the effect of TGF-β1 in the vein wall, namely on the gene expression of selected MMP, TIMP and TGF-β1 receptors. Methods Healthy vein samples were harvested from eight subjects who underwent coronary bypass graft surgery with great saphenous vein. Each vein sample was divided into two segments, which were cultivated separately in vitro (one of the segments had TGF-β1 added) and then submitted to gene expression analysis. Results In the TGF-β1 supplemented group, there was a general increase in the mean gene expression. Specifically, expression of MMP9, MMP12, TIMP1 and TIMP2 were statistically significant. Conclusion The results of this study demonstrate that the gene expression of MMP9, MMP12, TIMP1 and TIMP2 was influenced by the addition of TGF-β1. These results may be translated to chronic venous insufficiency framework and suggest involvement of TGF-β1 in the vein wall pathology.

European Council resolutions on tattoo ink introduce sterility and preservation of inks to protect customers. Inks used in Denmark are typically purchased over the internet from international suppliers and manufacturers from the US and the UK. In Denmark tattoo inks are regulated and labelled according to REACH as if they were plain chemicals. The objective of this study was to check the microbial product safety of unopened and opened tattoo ink stock bottles. Packaging, labelling, preservation, sterility and contamination with micro-organisms were studied. Physical inspection and culture of bacteria and fungi. Six of 58 unopened stock bottles (10%) were contaminated with bacteria and one of six samples (17%) of previously used stock bottles was contaminated. The bacterial species represented bacteria considered pathogenic in humans as well as non-pathogenic environmental bacteria. Yeast or moulds were detected in none of the samples. A total of 31% of the manufacturers informed only about the brand name. No information about content, sterility, risks or expiry date was indicated on the label. A total of 42% claimed sterility of their inks. A total of 54% labelled a maximum period of durability of typically 2-3 years. The physical sealing was leaking in 28% of the products. The European Council resolutions regarding safety of tattoo inks are not effective. Stock bottles of tattoo ink may contain bacteria pathogenic to humans and environmental bacteria, and packaging, labelling and preservation of inks are of inadequate quality. Claim of sterility can be erroneous. © 2011 The Authors. Journal of the European Academy of Dermatology and Venereology © 2011 European Academy of Dermatology and Venereology.

Background The color Doppler, a better investigation to identify the perforators objectively has replaced the clinical examination for the same. However, this has led to a significant number of negative explorations and cosmetic disfigurement. Objective To compare the efficacy of the clinical tests combined with the color Doppler versus color Doppler alone to identify the perforator incompetence during the surgery for primary varicose veins of the lower limb. Methods This was a prospective analytical study, including 61 lower limb varicose vein patients who belonged to the Clinical-Etiology-Anatomy-Pathophysiology (CEAP) class four-six, planned for the surgical treatment for perforator incompetence, excluding those requiring additional vascular or nonvascular procedure, recurrent varicose veins and those who had injection sclerotherapy prior to the surgery. The clinical tests, including Trendelenburg's test, multiple tourniquet tests and, the Fegan's tests were performed and incompetent perforators were marked on a template as 'C' to indicate the clinically positive perforator incompetence. The patients were then examined with the color Doppler ultrasound and the pathological incompetent perforators were marked as 'D'. The surgical management of the perforator incompetence was done by stab ligation. The incision was made in the color Doppler 'D' marked sites as it has been the standard protocol. The number of incompetent perforators identified during the surgical exploration were categorized as 'D' positive or 'C' and 'D' positive and were recorded in the specified proforma. Results It was found that the mean number of the perforator incompetence identified by the color Doppler alone was 8.2 whereas during the surgery, only a mean of six perforators was identified, leading to 20 unnecessary explorations per 10 patients (8.2 vs. 6; mean difference 2.229; P <0.001).

AIM: To tattoo gastric mucosa with a novel medical device which could be used to monitor and follow-up gastric mucosal lesions. METHODS: Combining endoscopic biopsy with sclerotherapy injection, we designed a new device that could perform biopsy and injection simultaneously. We performed endoscopies on a pig by using a novel endoscope tattoo biopsy forceps for 15 mo. At the same time, we used two-step method combining sclerotherapy injection needle with endoscopic biopsy. The acuity, inflammation and duration of endoscopy were compared between two methods. RESULTS: Compared with the old two-step method, although the inflammation induced by our new device was similar, the duration of procedure was markedly decreased and the acuity of tattooing was better than the old two-step method. All characteristics of the novel device complied with national safety guidelines. Follow-up gastroscopy after 15 mo showed the stained site with injection of 1:100 0.5 mL of India ink was still markedly visible with little inflammatory reaction. CONCLUSION: Endoscopic tattooing biopsy forceps can be widely used in monitoring precancerous lesions. Its safety and effectiveness has been established in animals. PMID:15793881

As the popularity of body art including tattoo ink has increased, the safety associated with it has become an important interest. In this study, twenty volatile organic compounds (VOCs) and two aldehydes in tattoo inks were identified and quantified. Headspace and gas chromatography-mass spectrometry (HS GC-MS) for the VOCs and HS GC-MS based on derivatization with 2,2,2-trifluoroethylhydrazine (TFEH) for aldehydes was developed. Benzene, chloroform, toluene, ethylbenzene, m-xylene, p-xylene, o-xylene, propylbenzene, chlorobenzene, tert-butylbenzene, 1,3,5-trimethylbenzene, styrene, 1,2,4-trimethylbenzene, 2-chlorotoluene, 4-chlorotoluene, 1,3-dichlorobenzene, 1,4-dichlorobenzene, 1,2-dichlorobenzene, 1,2,4-trichlorobenzene and isopropyl alcohol were detected with the concentration range of 0.02-207,000 mg/kg in 16 different tattoo inks. Formaldehyde and acetaldehyde were detected with the concentration range of 0.4-308 mg/kg in the same samples. Our analytical results represent solvents used intentionally or non-intentionally in tattoo inks, and thus they may provide important information for national regulation. © The Author 2016.

The skin is an attractive organ for immunization because of the presence of antigen-presenting cells. Intradermal delivery via tattooing has demonstrated superior vaccine immunogenicity of DNA vaccines in comparison to conventional delivery methods. In this study, we explored the efficacy of tattoo injection of a tumor vaccine based on recombinant Semliki Forest virus replicon particles (rSFV) targeting human papillomavirus (HPV). Tattoo injection of rSFV particles resulted in antigen expression in both the skin and draining lymph nodes. In comparison with intramuscular injection, the overall antigen expression determined at the site of administration and draining lymph nodes was 10-fold lower upon tattoo injection. Delivery of SFV particles encoding the E6 and E7 antigens of human papillomavirus type 16 (SFVeE6,7) via tattooing resulted in HPV-specific cytotoxic T cells and in vivo therapeutic antitumor response. Strikingly, despite the observed lower overall transgene expression, SFVeE6,7 delivered via tattoo injection resulted in higher or equal levels of immune responses as compared to intramuscular injection. The intrinsic immunogenic potential of tattooing provides a benefit for immunotherapy based on an alphavirus.

Hundreds of millions of people worldwide have tattoos, which predominantly contain black inks consisting of soot products like Carbon Black or polycyclic aromatic hydrocarbons (PAH). We recently found up to 200 μg/g of PAH in commercial black inks. After skin tattooing, a substantial part of the ink and PAH should be transported to other anatomical sites like the regional lymph nodes. To allow a first estimation of health risk, we aimed to extract and quantify the amount of PAH in black tattooed skin and the regional lymph nodes of pre-existing tattoos. Firstly, we established an extraction method by using HPLC-DAD technology that enables the quantification of PAH concentrations in human tissue. After that, 16 specimens of human tattooed skin and corresponding regional lymph nodes were included in the study. All skin specimen and lymph nodes appeared deep black. The specimens were digested and tested for 20 different PAH at the same time.PAH were found in twelve of the 16 tattooed skin specimens and in eleven regional lymph nodes. The PAH concentration ranged from 0.1-0.6 μg/cm2 in the tattooed skin and 0.1-11.8 μg/g in the lymph nodes. Two major conclusions can be drawn from the present results. Firstly, PAH in black inks stay partially in skin or can be found in the regional lymph nodes. Secondly, the major part of tattooed PAH had disappeared from skin or might be found in other organs than skin and lymph nodes. Thus, beside inhalation and ingestion, tattooing has proven to be an additional, direct and effective route of PAH uptake into the human body.

Henna tattoos are a very common practice in the adolescent population. Henna is very often admixed with para-phenylenediamine (PPDA) to improve the appearance of the tattoo. PPDA is a potent allergen, and is a frequent cause of allergic contact dermatitis (ACD). A study was conducted on the results of 726 consecutive children who had been patch tested in the University General Hospital Consortium of Valencia between 1980 and 2015. Almost half (49.7%; (361 cases) of the children had one or more positive patch test findings, with 4.7% (34) being allergic to PPDA. Mean age of patients allergic to PPDA was 12.4 years, and 44.2% were male. There were 2 cases (5.9%) of atopic dermatitis. Of the positive reactions, 73.5% were considered to be current clinically relevant. The sensitisation origin was a Henna tattoo in 50% of cases. PPDA sensitisation is relatively common in the child and adolescent population. The most frequent origin is the performing of Henna tattoos adulterated with PPDA. Adolescents are at the higher risk of developing ACD due to Henna tattoos. Henna tattooing should be strongly discouraged in children. Copyright © 2016 Asociación Española de Pediatría.

Skin tattoos on the feet, legs, and lower abdominal wall are progressively gaining popularity. Consequently, the number of tattooed women with cervical cancer has significantly increased in the last decade. However, pigments of tattoo ink can be transported to regional lymph nodes and potentially clog lymphatic pathways that might also be used by sentinel labeling substances. Therefore, here we report whether the presence of tattoo ink affected pelvic lymph nodes in women with early cervical cancer and discuss its potential oncologic and surgical consequences. Prospective observational study. University Hospital in Hamburg, Germany (Canadian Task Force classification II2). Women affected by cervical cancer. Between January 2014 and May 2016, 267 laparoscopic oncologic operations, including at least a pelvic sentinel or complete lymphadenectomy, were performed in the Department of Advanced Surgical and Oncologic Gynecology, Asklepios Hospital, Hamburg, Germany. Among these, 191 patients were affected by cervical cancer. Data of patients in whom dyed lymph nodes without the use of patent blue as a sentinel marker or different from blue-colored pelvic lymph nodes in the case of sentinel procedure were identified and prospectively collected. In 9 patients, skin tattoos localized in the lower extremities caused discoloration of at least 1 pelvic lymph node. This effect was observed in 40% of women (9/23) with tattoos in this area of the body. Mean patient age was 34 years (range, 27-56). All women had cutaneous tattoos on their feet or legs, and in 1 woman an additional tattoo situated on the inferior abdominal wall was observed. The stage of cervical cancer was FIGO IB1 in all cases. One woman was at the 16th week of gestation at the time of cancer diagnosis. On average, 26 pelvic lymph nodes (range, 11-51) were harvested from both pelvic basin sides. None of the removed lymph nodes was tumor involved. Three patients (33%) developed postoperatively infected

Previous studies on psychosocial aspects of tattooing have not examined prospective changes in self- and body-related attitudes as a result of obtaining a tattoo. In the present study, 82 British residents obtaining their first tattoo completed measures of state appearance anxiety and dissatisfaction prior to, and immediately after, obtaining a tattoo. They also completed measures of trait body appreciation, distinctive appearance investment, self-ascribed uniqueness, social physique anxiety, and self-esteem before obtaining a tattoo and three weeks later. Results showed that both women and men had significantly lower appearance anxiety and dissatisfaction immediately after obtaining their tattoo, and significantly higher body appreciation, distinctive appearance investment, self-ascribed uniqueness, and self-esteem after three weeks. Women reported greater social physique anxiety after three weeks, whereas men reported lower anxiety. These results are discussed in relation to the positive impacts of obtaining body art and the mainstreaming of tattooing in Western societies. Copyright © 2011 Elsevier Ltd. All rights reserved.

Tattoo-associated uveitis with or without systemic sarcoidosis: a comparative review of the literature.

Kluger, N

2018-05-15

Sarcoidosis is a systemic disease of unknown aetiology characterized by the presence of non-caseating epithelioid cell granulomas in multiple organs, mainly the lungs and the lymphatic system. It is also one of the leading cause of inflammatory eye diseases. For the past 70 years, sarcoidal granulomas on tattoos and permanent make-up have been documented. They can be the first and sometimes unique cutaneous manifestation of systemic sarcoidosis. A few cases of sarcoidosis with uveitis and granulomatous reactions within tattoos have been described. However, since the end 60s, a singular entity has been reported associating isolated uveitis with granulomatous cutaneous reaction restricted to tattoos in the notable absence of systemic sarcoidosis. It remains unclear whether this entity must be distinguished from sarcoidosis. This review summarizes the currently available data on this topic and compares cases of sarcoidosis with granulomatous tattoo reaction and uveitis to the cases without notable sarcoidosis. We propose the acronym TAGU (TAttoo Granulomas with Uveitis) as an exclusion diagnosis that emcompasses the patients for whom we fail to find any sarcoidosis or other causes after extensive investigation. © 2018 European Academy of Dermatology and Venereology.

Body piercing and tattooing are increasingly common. As well as the risk of infection and scarring, allergic reactions are also reported. This is the first multi-centre study to assess the frequency of consultations for allergy. Of the 138 allergologists who answered our two questionnaires, 7.9% reported allergic reactions associated with body piercing and 18.9% identified allergies associated with temporary henna-based tattoos. Contact eczema, rhinitis and urticaria were related to nickel allergy. Contact eczema, generalized eczema, pruritus and edema were caused by tattoos. In 20 out of 28 cases, sensitization to para-phenylenediamine (PPD) was observed. The authors review the literature, underscoring the risk of serious allergy to PPD, the need for long-term monitoring of the risk of skin lymphocytoma, the difficulties met during treatment and the necessity of regulating tattooing and body piercing practices.

Q-switched (QS) lasers are the gold standard for tattoo removal. The purpose of the present study was to gain a more comprehensive understanding of the factors that influence the efficacy of QS lasers and their associated complications in the removal of tattoos in China. Clinical data of 266 patients were analyzed retrospectively. The tattoo clearance rate was evaluated using the 4-point scale. The Cox regression model was applied to analyze the factors that affected the efficacy of QS lasers in tattoo removal. In addition, treatment-related adverse reactions were analyzed. The results showed that several variables had a statistically significant effect (p < 0.05) on the efficacy of QS laser-mediated tattoo removal treatment, including the patients' age, the tattoo's age, type, color, or ink density and the number of treatments. A variety of adverse responses occurred during the laser treatment. The overall incidence of adverse responses was approximately 24.06%, including pigmentation, hypopigmentation, bulla formation, allergic reactions, and skin texture changes or hypertrophic scarring. Some factors may influence the efficacy of QS lasers in the treatment of tattoos and certain adverse reactions may occur during this process.

Third-harmonic generation (THG) microscopy has been reported to provide intrinsic contrast in elastic fibers, cytoplasmic membrane, nucleus, actin filaments, lipid bodies, hemoglobin, and melanin in human skin. For advanced molecular imaging, exogenous contrast agents are developed for a higher structural or molecular specificity. We demonstrate the potential of the commonly adopted tattoo dye as a THG contrast agent for in vivo optical biopsy of human skin. Spectroscopy and microscopy experiments were performed on cultured cells with tattoo dyes, in tattooed mouse skin, and in tattooed human skin to demonstrate the THG enhancement effect. Compared with other absorbing dyes or nanoparticles used as exogenous THG contrast agents, tattoo dyes are widely adopted in human skin so that future clinical biocompatibility evaluation is relatively achievable. Combined with the demonstrated THG enhancement effect, tattoo dyes show their promise for future clinical imaging applications.

Although technology and tattoo removal methods continue to evolve, yellow pigment clearance continues to be challenging and usually unsuccessful. We describe a case series of six tattoos containing yellow ink, successfully treated with a frequency-doubled Nd:YAG 532-nm picosecond laser. Case series with six subjects participating for the treatment of multicolored tattoos that contain yellow pigment. Treatments performed with a frequency-doubled Nd:YAG 532-nm picosecond laser at 6-8 week intervals. One subject achieved complete clearance of the treated site after one session, and five subjects required 2-4 treatments to achieve over 75% clearance. Minimal downtime was experienced, and no scarring or textural skin changes were observed in any of the treated sites. This is the first case series that demonstrates effective and consistent reduction of yellow tattoo ink using a frequency doubled Nd:YAG 532-nm laser with a picosecond pulse duration. Treatments were well tolerated and subjects had positive outcomes. This is a small observational case series from an ongoing clinical trial, and studies with a larger sample size and comparative group are needed in the future. © 2015 Wiley Periodicals, Inc.

Regulation of tattooing in Minneapolis and St. Paul, Minnesota: tattooists' attitudes and relationship between regulation and practice.

Raymond, Monica J; Halcón, Linda L; Pirie, Phyllis L

2003-01-01

This study investigated tattooists' attitudes regarding government regulation and the relationship between existing tattooing regulation and tattooists' knowledge and practice of infection control. Self-reported and observational data were collected in a cross-sectional study of professional tattooists. A written survey was used to investigate knowledge and practice of infection control and attitudes toward government regulation. Infection control practice was also examined through direct observation of tattooing. Rating scales were used to compare tattoo artists subject to local tattooing ordinances with those in areas without ordinances. Sixty-one tattooists (45 regulated, 16 unregulated) completed surveys and 25 (17 regulated, 8 unregulated) were observed. Attitudes toward regulation were generally positive. Most participants supported health department inspections and training requirements. The presence of local tattooing ordinances was not associated with tattooists' knowledge (p=0.53), but was associated with self-reported practices (p=0.05). A more positive attitude toward regulation was associated with the use of more self-reported infection control procedures (p<0.01). Tattoo artists in areas with local tattooing ordinances may implement more bloodborne pathogen precautions than those in areas without ordinances, despite working from a similar knowledge base. Tattooists most in need of improvement may be difficult to reach due to opposition to government intrusion. Federal guidelines, clarification of OSHA rules applying to tattooists, and statewide regulation are needed. Tattooists should be involved in the development of regulations.

Q-switched laser systems have been used for removal of tattoo-related carbon, graphite, and other particles. We assessed elimination of traumatic tattoos of different origin with Q-switched alexandrite laser in nine patients. Fluence threshold was determined and a spot test was made. Q-switched alexandrite laser, with a fluence range 4.5-8.0 J/cm(2) (mean, 7.16 +/- 1.18), was used at 4-5-week intervals. Total treatment ranged from 3-12 sessions (mean, 6.1 +/- 3.6 sessions). Double-pulse technique was used in black/black-bluish areas, but single-shot was applied to slate-gray pigment. More than 95% lightening was achieved in five patients after 5.2 +/- 2.3 sessions, and >75% lightening in six subjects after 6.1 +/- 3.1 sessions of treatment. Blacktop, surgical pen, and gravel tattoos presented a better response than gunpowder/fireworks tattoos (>95% vs. 68.7 +/- 23.9% clearance), or tattoos of unknown origin (>95% vs. 62.5 +/- 53% clearance). Epidermal splattering and pinpoint bleeding were observed in one case. No pigmentary alteration or scarring was seen. The Q-switched alexandrite laser is a useful system for removal of traumatic tattoos of diverse origin. The best response (>95% clearance) was achieved in blacktop, surgical pen, and gravel tattoos, although an acceptable degree of lightening may be obtained in tattoos due to gunpowder or fireworks.

Eosinophilic cellulitis (Wells’ syndrome) is an uncommon condition of unknown etiology. Wells’ syndrome is usually seen in adulthood but very rare in childhood. Although pathogenesis of the disease is not very clear, it is a hypersensitivity reaction developing against a variety of exogenous and endogenous antigenic stimuli. Paraphenylenediamine is a strong allergen frequently used as a temporary henna tattoo, which makes the color darker. Here, a 9-year-old male patient with Wells’ syndrome is presented, which developed following a temporary henna tattoo and shown by the patch test sensitivity to paraphenylenediamine. PMID:25395929

Chronic venous disease is a common condition leading to varicose veins, leg edema, post-thrombotic syndrome and venous ulcerations. Ultrasound (US) is the main modality for examination of venous disease. Color Doppler and occasionally spectral Doppler US (SDUS) are used for evaluation of the venous flow. Peak velocities measured by SDUS are rarely used in a clinical setting for evaluating chronic venous disease due to inadequate reproducibility mainly caused by the angle dependency of the estimate. However, estimations of blood velocities are of importance in characterizing venous disease. Transverse Oscillation US (TOUS), a non-invasive angle independent method, has been implemented on a commercial scanner. TOUS's advantage compared to SDUS is a more elaborate visualization of complex flow. The aim of this study was to evaluate, whether TOUS perform equal to SDUS for recording velocities in the veins of the lower limbs. Four volunteers were recruited for the study. A standardized flow was provoked with a cuff compression-decompression system placed around the lower leg. The average peak velocity in the popliteal vein of the four volunteers was 151.5 cm/s for SDUS and 105.9 cm/s for TOUS (p <0.001). The average of the peak velocity standard deviations (SD) were 17.0 cm/s for SDUS and 13.1 cm/s for TOUS (p <0.005). The study indicates that TOUS estimates lower peak velocity with improved SD when compared to SDUS. TOUS may be a tool for evaluation of venous disease providing quantitative measures for the evaluation of venous blood flow.

The implementation of regulation for tattoo ink ingredients across Europe has generated the need for analytical methods suitable to identify prohibited compounds. Common challenges of this subject are the poor solubility and the lack of volatility for most pigments and polymers applied in tattoo inks. Here, we present pyrolysis coupled to online gas chromatography and electron impact ionization mass spectrometry (py-GC/MS) as quick and reliable tool for pigment identification using both purified pigments and tattoo ink formulations. Some 36 organic pigments frequently used in tattoo inks were subjected to py-GC/MS with the aim to establish a pyrogram library. To cross-validate pigment identification, 28 commercially available tattoo inks as well as 18 self-made pigment mixtures were analyzed. Pyrograms of inks and mixtures were evaluated by two different means to work out the most reliable and fastest strategy for an otherwise rather time-consuming data review. Using this approach, the declaration of tattoo pigments currently used on the market could be verified. The pyrolysis library presented here is also assumed suitable to predict decomposition patterns of pigments when affected by other degradation scenarios, such as sunlight exposure or laser irradiation. Thus, the consumers' risk associated with the exposure to toxicologically relevant substances that originate from pigment decomposition in the dermal layers of the skin can be assessed. Differentiation between more or less harmful pigments for this field of application now will become feasible.

Matrix Metalloproteinases as Regulators of Vein Structure and Function: Implications in Chronic Venous Disease.

PubMed

MacColl, Elisabeth; Khalil, Raouf A

2015-12-01

Lower-extremity veins have efficient wall structure and function and competent valves that permit upward movement of deoxygenated blood toward the heart against hydrostatic venous pressure. Matrix metalloproteinases (MMPs) play an important role in maintaining vein wall structure and function. MMPs are zinc-binding endopeptidases secreted as inactive pro-MMPs by fibroblasts, vascular smooth muscle (VSM), and leukocytes. Pro-MMPs are activated by various activators including other MMPs and proteinases. MMPs cause degradation of extracellular matrix (ECM) proteins such as collagen and elastin, and could have additional effects on the endothelium, as well as VSM cell migration, proliferation, Ca(2+) signaling, and contraction. Increased lower-extremity hydrostatic venous pressure is thought to induce hypoxia-inducible factors and other MMP inducers/activators such as extracellular matrix metalloproteinase inducer, prostanoids, chymase, and hormones, leading to increased MMP expression/activity, ECM degradation, VSM relaxation, and venous dilation. Leukocyte infiltration and inflammation of the vein wall cause further increases in MMPs, vein wall dilation, valve degradation, and different clinical stages of chronic venous disease (CVD), including varicose veins (VVs). VVs are characterized by ECM imbalance, incompetent valves, venous reflux, wall dilation, and tortuosity. VVs often show increased MMP levels, but may show no change or decreased levels, depending on the VV region (atrophic regions with little ECM versus hypertrophic regions with abundant ECM) and MMP form (inactive pro-MMP versus active MMP). Management of VVs includes compression stockings, venotonics, and surgical obliteration or removal. Because these approaches do not treat the causes of VVs, alternative methods are being developed. In addition to endogenous tissue inhibitors of MMPs, synthetic MMP inhibitors have been developed, and their effects in the treatment of VVs need to be examined

Tattooing and use of permanent makeup (PMU) has dramatically increased over the last decade, with a concomitant increase in ink-related infections. The aim of this study was to determine whether micro-organisms are present, and if so, the number and their identification in the commercial tattoo and PMU inks available in the United States. We surveyed 85 unopened tattoo and PMU inks, purchased from 13 companies. We incubated 100 μl of ink samples on trypticase soy agar plates for bacterial growth, 7H10 Middlebrook medium for mycobacterial growth, and Sabouraud dextrose medium for fungal growth. In total, 42 inks were contaminated with micro-organisms (49%). Thirty-three inks were contaminated with bacteria, 2 inks with fungi, and 7 inks had both bacterial and fungal growth. Mycobacteria were not detected in any of the examined tattoo and PMU inks. In 26 inks, microbial concentrations ranged between 10 1 and 10 3 CFU per ml, but higher counts (>10 3 CFU per ml) were recorded in 16 inks. We identified 83 bacteria by their 16S rDNA sequences, including 20 genera and 49 species. Strains of Bacillus spp. (53%) were dominant, followed by Lysinibacillus fusiformis (7%) and Pseudomonas aeruginosa (5%). Thirty-four (41%) possibly clinically relevant strains were identified, including P. aeruginosa, Dermacoccus barathri and Roseomonas mucosa, some of which have been previously reported to be associated with human skin infections. The results indicate that commercial tattoo and PMU inks on the US market surveyed in this study contain a wide range of micro-organisms, including pathogenic bacteria. Microbial contaminants in tattoo and PMU inks are an emerging safety concern for public health. This study provides evidence that microbial contamination of tattoo and PMU inks available in the United States is more common than previously thought and highlights the importance of monitoring these products for potentially pathogenic micro-organisms.

2004-05-01

Non-invasive radiofrequency and endovascular technologies are becoming increasingly popular in the treatment of superficial venous incompetence. In conjunction with stab avulsion of truncal varicosities, these technologies have been able to address functional as well as cosmetic superficial venous incompetence in a non-invasive fashion. The present study presents a 2-year follow-up of 30 patients with combined axial incompetence of the greater saphenous vein (GSV) in conjunction with truncal varicosities treated with combination diode laser technology and ambulatory phlebectomy. Thirty patients (mean age 49 years) with Sapheno-Femoral Junction reflux associated with GSV incompetence (mean 9.2 x 8.5 mm) and enlarged branch varicosities, as documented by Duplex ultrasound, were enrolled. Patients were treated with an endovascular diode laser (810 nm, 14 W, continuous mode), followed by ambulatory phlebectomy of residual truncal varicosities. Patients were examined 3, 6, 12 and 24 months following this procedure to determine the long-term efficacy of this procedure. A 2-year closure rate of 96.8% was documented by Duplex evaluation. All 273 ambulatory phlebectomy vein segments were eradicated. Two cases of transient hyperpigmentation and one case of telangiectatic matting were documented. The combination of endovascular laser and ambulatory phlebectomy appear to be an effective and safe treatment approach for the management of combined saphenous and truncal varicose vein incompetence.

This study evaluated the readability, accessibility, usability, and reliability of vascular surgery information on the Internet in the English language. The Google, Yahoo, and MSN/Bing search engines were searched for "carotid endarterectomy," "EVAR or endovascular aneurysm repair," and "varicose veins or varicose veins surgery." The first 50 Web sites from each search engine for each topic were analyzed. The Flesch Reading Ease Score and Gunning Fog Index were calculated to assess readability. The LIDA tool (Minervation Ltd, Oxford, UK) was used to assess accessibility, usability, and reliability. The Web sites were difficult to read and comprehend. The mean Flesch Reading Ease scores were 53.53 for carotid endarterectomy, 50.53 for endovascular aneurysm repair, and 58.59 for varicose veins. The mean Gunning Fog Index scores were 12.3 for carotid endarterectomy, 12.12 for endovascular aneurysm repair, and 10.69 for varicose veins. The LIDA values for accessibility were good, but the results for usability and reliability were poor. Internet information on vascular surgical conditions and procedures is poorly written and unreliable. We suggest that health professionals should recommend Web sites that are easy to read and contain high-quality surgical information. Medical information on the Internet must be readable, accessible, usable, and reliable. Copyright © 2012 Society for Vascular Surgery. Published by Mosby, Inc. All rights reserved.

2014-12-01

Juvenile crime affects not only the victims of the crime but also the delinquents' future. How to prevent adolescent criminal behavior has become an important public policy issue. This study contributes to this interesting issue by examining the relationship between tattooing and adolescents' criminal behavior. In particular, this study investigates whether or not having a tattoo/tattoos is connected to the incidence of various criminal activities, including: larceny, robbery, fraud, assault, drug use, and homicide. A unique sample of 973 juvenile detainees drawn from the administrative profiles in Taiwan and the coarsened exact matching method were utilized. Results show that compared to their nontattooed counterparts, tattooed juvenile detainees were significantly more likely to commit fraud, assault, drug abuse, and homicide by 3%, 13%, 9%, and 9%, respectively. In contrast, tattooing was not significantly associated with larceny or robbery. From a policy perspective, given the significant link between tattooing and criminal behavior, the presence of a tattoo in adolescents may serve as a valuable indicator regarding adolescents' high probability of committing crimes. © 2014 Society for Risk Analysis.

The aim of the study was to determine the level of life satisfaction and the various dimensions of self-esteem of pierced or tattooed people, and evaluate their mental health, compared to those without similar body modifications. The study was conducted on a sample of 449 people aged 16-58 years (mean age 26.7 ± 6.35), of whom 308 had body modifications: tattoo (n = 90), body piercings in places other than the ear lobe (n = 53), or both tattoos and piercings (n = 165). The control group consisted of 141 people without such modifications. The participants completed a questionnaire concerning their socio-demographic status, as well as the following psychological tests: The Satisfaction with Life Scale (SWLS), Multidimensional Self-Esteem Inventory (MSEI) and General Health Questionnaire (GHQ-28). Our findings show no significant differences in terms of life satisfaction between the group with tattoos or piercings and the control group. People with body modifications were characterized by higher self-esteem, with regard to their competence and leadership abilities. They also display fewer symptoms of social impairment and sleep disorders than the control group. Tattoos and piercings should not be considered as indicators of psychopathology.

Phallic decoration in paleolithic art: genital scarification, piercing and tattoos.

The primitive anthropological meaning of genital ornamentation is not clearly defined and the origin of penile intervention for decorative purposes is lost in time. Corporeal decoration was practiced in the Upper Paleolithic period. We discuss the existing evidence on the practice of phallic piercing, scarring and tattooing in prehistory. We studied the archaeological and artistic evidence regarding explicit genital male representations in portable art made in Europe approximately 38,000 to 11,000 years ago with special emphasis on decorations suggesting genital ornamentation. Archaeological evidence that has survived to our day includes 42 phallic pieces, of which 30 (71.4%) show intentional marks to a different extent with a probable decorative purpose. Of these ornamental elements 18 (60%) were recovered from the upper Magdalenian period (11,000 to 12,700 years ago) in France and Spain, and 23 (76.7%) belong to the category of perforated batons. Decorations show lines (70% of objects), plaques (26.7%), dots/holes (23.3%) or even human/animal forms (13.3%). These designs most probably represent skin scarification, cutting, piercing and tattooing. Notably there are some technical similarities between the motifs represented and some designs present in symbolic cave wall art. This evidence may show the anthropological origin of current male genital piercing and tattooing. European Paleolithic art shows decoration explicitly represented in a high proportion of portable art objects with a phallic form that have survived to our day. Decorative rituals of male genital tattooing, piercing and scarification may have been practiced during Paleolithic times.

Objective This study aims to present the early results of a retrospective study of the use of novel n-butyl-2-cyanoacrylate (VenaBlock)-based nontumescent endovenous ablation with a guiding light for the treatment of patients with varicose veins. Methods Patients with lower limb venous insufficiency were treated with n-butyl-2-cyanoacrylate (VenaBlock Venous Closure System) between April 2016 and July 2016. The study enrolled adults aged 21-70 years with symptomatic moderate to severe varicosities (C2-C4b) and great saphenous vein reflux lasting longer than 0.5 s with great saphenous vein diameter between 5.5 and 15 mm assessed in the standing position. No compression stockings were used after the procedure. Duplex ultrasound imaging and clinical follow-up were performed on the third day, first month, sixth month, and 12th month. Clinical, etiological, anatomical, pathophysiological classification; venous clinical severity score; and completed Aberdeen varicose vein questionnaire were recorded. Results Five hundred thirty-eight patients with great saphenous vein incompetency underwent n-butyl-2-cyanoacrylate ablation. The mean ablation length was 25.69 ± 4.8 cm, and the average amount of n-butyl-2-cyanoacrylate delivered was 0.87 ± 0.15 ml. The mean procedure time was 11.7 ± 4.9 min. Procedural success was 100%, and complete occlusion was observed after treatment and at the third-day follow-up. We observed ecchymosis in five patients (1.00%) at the entry site at the third-day follow-up. Phlebitis was encountered with six (1.20%) patients. No skin pigmentation, hematoma, paresthesia, deep vein thrombosis, or pulmonary embolism was observed. Kaplan-Meier analysis yielded an occlusion rate of 99.4% at the 12-month follow-up. All patients had significant improvement in venous clinical severity score and Aberdeen varicose vein questionnaire scores postoperatively ( p <0.0001). Venous clinical severity score scores decreased from 5.43 ± 0.87 to

The aim of the study was to evaluate the efficacy of tattoo removal treatments using the 1064-nm Q-switched (QS) Nd:YAG laser. Today, QS lasers appear to be the most common, effective, and safest methods to treat unwanted markings. A total of 64 patients with 75 unwanted tattoos were enrolled in the study. Tattoo clearance was evaluated according to the color intensity - concentration of pigment: group I (34) - black; group II (41) - gray. Consideration included methods of tattooing and tattoo techniques. In group I, after the first treatment session the median of clearance was 30% (10-50%), while in group II, the median was 50% (40-70%). After the second treatment session, median in group I increased to 40% (30-50%). Median of group II increased to 70% (50-80%). The highest number of treatment in group I was 7. After that, the median grew to 75%, while the highest amount of treatment in group II was 5 and a median of 90% was achieved. Effects were dependent upon the amount of ink deposited in the tissue. Old amateur tattoos and tattoos containing small quantities of ink (technique: shading and lines) demonstrated the quickest and the most efficacious results. Tattoos with large quantities of ink, obtained by filling, required the greatest number of treatment sessions. The final outcome in tattoo clearing can only be assessed following treatment completion, which may in some cases take 2-3 years. Presumably, in some cases, complete clearance is impossible. © 2015 Wiley Periodicals, Inc.

This article describes the fabrication, characterization and application of an epidermal temporary-transfer tattoo-based potentiometric sensor, coupled with a miniaturized wearable wireless transceiver, for real-time monitoring of sodium in the human perspiration. Sodium excreted during perspiration is an excellent marker for electrolyte imbalance and provides valuable information regarding an individual's physical and mental wellbeing. The realization of the new skin-worn non-invasive tattoo-like sensing device has been realized by amalgamating several state-of-the-art thick film, laser printing, solid-state potentiometry, fluidics and wireless technologies. The resulting tattoo-based potentiometric sodium sensor displays a rapid near-Nernstian response with negligible carryover effects, and good resiliency against various mechanical deformations experienced by the human epidermis. On-body testing of the tattoo sensor coupled to a wireless transceiver during exercise activity demonstrated its ability to continuously monitor sweat sodium dynamics. The real-time sweat sodium concentration was transmitted wirelessly via a body-worn transceiver from the sodium tattoo sensor to a notebook while the subjects perspired on a stationary cycle. The favorable analytical performance along with the wearable nature of the wireless transceiver makes the new epidermal potentiometric sensing system attractive for continuous monitoring the sodium dynamics in human perspiration during diverse activities relevant to the healthcare, fitness, military, healthcare and skin-care domains. © 2013 Published by Elsevier B.V.

Tattoos are very popular. Widely used standard industrial pigments are used. The field lacks basic knowledge concerning pigments, epidemiology and complications such as allergy, granulomas, skin cancer and foreign body reactions. The risks associated with laser treatment are unknown. Studies have suggested that some degradation products are carcinogenic. The field lacks formal regulation at national and European levels and EU had to give up attempts to control the area in 2003 because of lack of knowledge in the field.

Magnolol inhibits venous remodeling in mice.

Kuk, Hanna; Arnold, Caroline; Meyer, Ralph; Hecker, Markus; Korff, Thomas

Due to gravity the venous vasculature in the lower extremities is exposed to elevated pressure levels which may be amplified by obesity or pregnancy. As a consequence, venules dilate and may be slowly transformed into varicose or spider veins. In fact, chronically elevated venous pressure was sufficient to cause the corkscrew-like enlargement of superficial veins in mice. We hypothesized that biomechanical activation of endothelial cells contributes to this process and investigated the inhibitory capacity of Magnolol in this context - a natural compound that features multiple properties counteracting cellular stress. While Magnolol did not influence endothelial capillary sprout formation, it interfered with proliferation, ERK1/2 activity, gelatinase activity as well as baseline production of reactive oxygen species in these cells or murine veins. The anti-oxidative and anti-proliferative capacity of Magnolol was mediated through stimulation of heme oxygenase-1 expression. Finally, local transdermal application of Magnolol attenuated pressure-mediated development of varicose/spider veins in mice and was accompanied by the absence of proliferating and MMP-2 positive endothelial cells. Collectively, our data identified Magnolol as a potent inhibitor of biomechanically evoked endothelial cell activity during pressure-mediated venous remodeling processes which contribute to the development of varicose and spider veins.

What little research has been done on methods of venous valve function recovery with radiofrequency has had disappointing results. Valvuloplasty has some supporters, but the majority of physicians do not consider it a valid therapeutic option. To test a new method of treating varicose veins based on their collagen structure. This procedure it is not a thermal treatment, but it is fast, with significant shrinking and preservation of the endothelium. In the laboratory, we subjected greater saphenous vein specimens to irradiation with a blue light-emitting diode generated (wavelength 450-480 nm) while a riboflavin solution (vitamin B2) was administered. The riboflavin acts as a cross-linking agent, and the blue light as the activator. In this photo-induced reaction, oxygen singlet is produced with oxidative deamination, forming new covalent bonds between collagen fibrils and water. In venous specimens, we demonstrated fast and significant shrinkaged without histologic evidence of endothelial damage and with evident change in mechanical properties of varicose veins. Photochemically induced collagen cross-linking to restructure varicose veins is only a research field but may become an important tool for recovery of vein diameter and valve function. © 2011 by the American Society for Dermatologic Surgery, Inc.

2015-01-01

Background: Q-switched neodymium: yttrium aluminum garnet (Nd: YAG) laser at a wavelength of 1064 nm primarily targets dermal melanin and black tattoo ink. Recent studies have shown that this laser is effective in treating black tattoos. There are few studies conducted in India for the same. Aim: The aim was to assess the effectiveness of Q-switched Nd: YAG laser (QSNYL) in the treatment of blue-black tattoos following 3 treatment sessions. Materials and Methods: This study, a prospective interventional study included a total of 12 blue-black tattoos. Following informed consent for the procedure, as well as for photographs, a questionnaire was administered, and improvement perceived by the patient was recorded. In addition, global assessment score (GAS) by a blinded physician was also recorded. Photographs were taken at baseline and at every follow-up. Each patient underwent three treatment sessions with 1064 nm QSNYL at 4–6 weekly intervals. Fluences ranged from 1.8 to 9 J/cm2. The follow-up was done monthly for 4 months from the first treatment session. The response was assessed by patient assessment (PA) and GAS by comparing photographs. Results: After three treatment sessions, although no patient achieved clearance, most patients showed good response with few adverse effects. An average of 64.1% (GAS) and 54.2% (PA) improvement was observed in 12 tattoos. Tattoos more than 10-year-old showed quicker clearing than those less than 10-year-old. Amateur tattoos also showed a better response in comparison to professional tattoos. Conclusion: Totally, 1064 nm QSNYL is safe and effective for lightening blue-black tattoos in pigmented Indian skin. All patients achieved near complete clearance following the continuation of treatment (an average of six sessions) although this was spaced at longer intervals. PMID:26677271

2018-01-01

Nowadays, about 12% of the European and 20% of the US population are tattooed. Rising concerns regarding consumer safety, led to legal restrictions on tattoo and permanent make-up (PMU) inks. Restrictions also include bans on certain colourants. Both ink types use organic pigments for colour-giving, plus inorganic pigments for white and black and colour tones. Pigments are only sparingly soluble in common solvents and occur as suspended particles in the ink matrix. Their detection and identification therefore pose a major challenge for laboratories involved in monitoring the legal compliance of tattoo inks and PMU. We overcame this challenge by developing a direct laser desorption ionisation time-of-flight mass spectrometry method, which included an easy sample clean up. The method proved to be capable of detecting and identifying organic pigments in almost all of the tested ink samples. Method validation and routine deployment during market surveys showed the method to be fit for purpose. Pigment screening of 396 tattoo inks and 55 PMU taken from the Swiss market between 2009 and 2017 lead to the following conclusions: Pigment variety is much greater in tattoo inks (18) than in PMU (10); four prohibited pigments (Pigment Green 7, Pigment Red 122, Pigment Violet 19 and 23) were found in both ink types; for PMU, these four pigments made up 12% of the pigment findings, compared to 32% for tattoo inks. Therefore, legal compliance of PMU was at a higher level. A comparison of pigments found with those declared on tattoo ink labels clearly showed that banned pigments are rarely declared, but rather masked by listing non present legal pigments and label forging; therefore, highlighting the urgency of widespread market controls.

Background and Objectives Although nanosecond‐domain lasers have been the mainstay of laser tattoo removal for decades, recent disruptive innovations in laser design have introduced a new class of commercial Q‐switched lasers that generate picosecond‐domain pulses. Study A picosecond‐domain, Nd:YAG laser with a KTP frequency‐doubling crystal was used to treat 31 decorative tattoos in 21 subjects. Safety and effectiveness were determined by blinded evaluation of digital images in this prospective clinical study. Results The average clearance overall as evaluated by blinded observers evaluating randomized digital photographs was 79 ± 0.9% (mean ± sem) after an average of 6.5 treatments. Of the 31 tattoos completing treatment, 6 had evidence of mild hyper‐ or hypo‐pigmentation by evaluation of photographs. Conclusion The 350 picosecond, 532 nm, and 450 picosecond 1,064 nm Nd:YAG laser is safe and effective for removing decorative tattoos. Lasers Surg. Med. 47:542–548, 2015. © 2015 The Authors.

The outcome of laser tattoo removal is dependent on the type of laser and characteristics of the tattoo. A rabbit model was developed to study the Q-switched ruby laser in the treatment of traumatic tattooing. On the backs of white New Zealand rabbits, three 3 cm patches were dermabraded and dressed with carbon black and antibiotic ointment. After a healing period of eight weeks, pre-treatment biopsies were obtained, and the rabbits were treated with the Q- switched ruby laser at various fluence settings with a pulse width of 34 nsec. At set intervals, further biopsies were obtained and studied with light and electron microscopic analysis, and photodocumentation was performed. Grossly, clearance of the tattooed areas was noted in the laser treated specimens. More effective clearance was observed with higher fluence treatment. No infections occurred, and hair regrowth was noted in all cases, though the rate seemed to be altered by laser treatment.

Pelvic congestion syndrome and left renal compression syndrome - clinical features and therapeutic approaches.

2016-01-01

Knowledge of the anatomy of the pelvic, gonadal and renal veins is important to understand pelvic congestion syndrome (PCS) and left renal vein compression syndrome (LRCS), which is also known as the nutcracker syndrome. LRCS is related to PCS and to the presence of vulvar, vaginal and pudendal varicose veins. The diagnosis of the two syndromes is difficult, and usually achieved with CT- or phlebography. The gold standard is the intravenous pressure measurement using conventional phlebography. The definition of PCS is described as pelvic pain, aggravated in the standing position and lasting for more than 6 months. Pain in the left flank and microhaematuria is seen in patients with LRCS. Women with multiple pregnancies are at increased risk of developing varicose vein recurrences with pelvic drainage and ovarian vein reflux after crossectomy and stripping of the great saphenous vein. The therapeutic options are: conservative treatment (medroxyprogesteron) or interventional (coiling of the ovarian vein) or operative treatment (clipping of the ovarian vein). Controlled prospective trials are needed to find the best treatment.

Decorative tattooing has been linked with a range of complications, with pseudolymphoma being unusual and challenging to manage. We report a case of tattoo-induced pseudolymphoma, who failed treatment with potent topical and intralesional steroids. She responded well to sequential treatment with ablative fractional resurfacing (AFR) followed by Q-Switched (QS) Nd:YAG 532 nm laser. Interestingly, we managed to document the clearance of her tattoo pigments after laser treatments on histology and would like to highlight the use of special stains such as the Grocott's Methenamine Silver (GMS) stain as a useful method to assess the presence of tattoo pigment in cases where dense inflammatory infiltrates are present.

2014-12-01

Q-switched laser treatments are considered the standard method for removing both regular and traumatic tattoos. Recently, the removal of tattoo ink using ablative fractional lasers has been reported. Ablative fractional CO2 laser and q-switched ruby laser treatments were used in a split-face mode to compare the safety and efficacy of the two types of laser in removing a traumatic tattoo caused by the explosion of a firework. A male patient suffering from a traumatic tattoo due to explosive deposits in his entire face was subjected to therapy. A series of eleven treatments were performed. The right side of the face was always treated using an ablative fractional CO2 laser, whereas the left side was treated only using a q-switched ruby laser. After a series of eleven treatments, the patient demonstrated a significant lightening on both sides of his traumatic tattoo, with no clinical difference. After the first six treatments, the patient displayed greater lightening on the right side of his face, whereas after another five treatments, the left side of the patient's face appeared lighter. No side effects were reported. In the initial stage of removing the traumatic tattoo, the ablative fractional laser treatment appeared to be as effective as the standard ruby laser therapy. However, from the 6th treatment onward, the ruby laser therapy was more effective. Although ablative fractional CO2 lasers have the potential to remove traumatic tattoos, they remain a second-line treatment option.

Determination of the thermal and physical properties of black tattoo ink using compound analysis.

Despite the widespread use of laser therapy in the removal of tattoos, comparatively little is known about its mechanism of action. There is a need for an improved understanding of the composition and thermal properties of the tattoo ink in order that simulations of laser therapy may be better informed and treatment parameters optimised. Scanning electron microscopy and time-of-flight secondary ion mass spectrometry identified that the relative proportions of the constituent compounds of the ink likely to exist in vivo are the following: carbon black pigment (89 %), carvacrol (5 %), eugenol (2 %), hexenol (3 %) and propylene glycol (1 %). Chemical compound property tables identify that changes in phase of these compounds lead to a considerable reduction in the density and thermal conductivity of the ink and an increase in its specific heat as temperature increases. These temperature-dependent values of density, thermal conductivity and specific heat are substantially different to the constant values, derived from water or graphite at a fixed temperature, which have been applied in the simulations of laser therapy as previously described in the literature. Accordingly, the thermal properties of black tattoo ink described in this study provide valuable information that may be used to improve simulations of tattoo laser therapy.

Dissolvable tattoo sensors: from science fiction to a viable technology

2017-01-01

Early surrealistic painting and science fiction movies have envisioned dissolvable tattoo electronic devices. In this paper, we will review the recent advances that transform that vision into a viable technology, with extended capabilities even beyond the early vision. Specifically, we focus on the discussion of a stretchable design for tattoo sensors and degradable materials for dissolvable sensors, in the form of inorganic devices with a performance comparable to modern electronics. Integration of these two technologies as well as the future developments of bio-integrated devices is also discussed. Many of the appealing ideas behind developments of these devices are drawn from nature and especially biological systems. Thus, bio-inspiration is believed to continue playing a key role in future devices for bio-integration and beyond.

Although there is no documented evidence that tattoo pigments can cause neurological complications, the implications of performing neuraxial anesthesia through tattooed skin are unknown. In this study, we aimed to assess whether spinal puncture performed through tattooed skin of rabbits determines changes over the spinal cord and meninges. In addition, we sought to evaluate the presence of ink fragments entrapped in spinal needles. Thirty-six young male adult rabbits, each weighing between 3400 and 3900 g and having a spine length between 38.5 and 39 cm, were divided by lot into 3 groups as follows: GI, spinal puncture through tattooed skin; GII, spinal puncture through tattooed skin and saline injection; and GIII, spinal puncture through skin free of tattoo and saline injection. After intravenous anesthesia with ketamine and xylazine, the subarachnoid space was punctured at S1-S2 under ultrasound guidance with a 22-gauge 2½ Quincke needle. Animals in GII and GIII received 5 μL/cm of spinal length (0.2 mL) of saline intrathecally. In GI, the needle tip was placed into the yellow ligament, and no solution was injected into the intrathecal space; after tattooed skin puncture, 1 mL of saline was injected through the needle over a histological slide to prepare a smear that was dyed by the Giemsa method to enable tissue identification if present. All animals remained in captivity for 21 days under medical observation and were killed by decapitation. The lumbosacral spinal cord portion was removed for histological analysis using hematoxylin-eosin stain. None of the animals had impaired motor function or decreased nociception during the period of clinical observation. None of the animals from the control group (GIII) showed signs of injuries to meninges. In GII, however, 4 animals presented with signs of meningeal injury. The main histological changes observed were focal areas of perivascular lymphoplasmacyte infiltration in the pia mater and arachnoid. There was no

Polycystic ovary syndrome (PCOS) causes vascular damage to arteries; however, there are no data for its effect on veins. Our aim was to clarify the effects of dihydrotestosterone (DHT)-induced PCOS both on venous biomechanics and on pharmacological reactivity in a rat model and to test the possible modulatory role of vitamin D3 (vitD). PCOS was induced in female Wistar rats by DHT treatment (83 μg/day, subcutaneous pellet). After 10 wk, the venous biomechanics, norepinephrine (NE)-induced contractility, and acetylcholine-induced relaxation were tested in saphenous veins from control animals and from animals treated with DHT or DHT with vitD using pressure angiography. Additionally, the expression levels of endothelial nitric oxide synthase (eNOS) and cyclooxygenase (COX-2) were measured using immunohistochemistry. Increased diameter, wall thickness, and distensibility as well as decreased vasoconstriction were detected after the DHT treatment. Concomitant vitD treatment lowered the mechanical load on the veins, reduced distensibility, and resulted in vessels that were more relaxed. Although there was no difference in the endothelial dilation tested using acetylcholine (ACh), the blocking effect of N(G)-nitro-l-arginine methyl ester (l-NAME) was lower and was accompanied by lower COX-2 expression in the endothelium after the DHT treatment. Supplementation with vitD prevented these alterations. eNOS expression did not differ among the three groups. We conclude that the hyperandrogenic state resulted in thicker vein walls. These veins showed early remodeling and altered vasorelaxant mechanisms similar to those of varicose veins. Alterations caused by the chronic DHT treatment were prevented partially by concomitant vitD administration. Copyright © 2014 the American Physiological Society.

Pregnancy may cause the onset of vaginal or vulvar varicosities that may be a concern for hemorrhage risk during childbirth. A 38-year-old female G4P1112 at 34 weeks and 1 day was referred to an outpatient OB/Gyn clinic for evaluation of a large vaginal mass. The referring provider had concern for malignancy. Lesions of the vulva were biopsied and found to be benign. For two months prior to presentation, she was experiencing discomfort with walking, yellow vaginal discharge, and dysuria. Treatment with fluconazole showed no improvement. She denied any personal or family history of malignancies, varicosities, or hepatic issues. Past surgical history was significant for laparoscopic cholecystectomy and two cesarean sections. A large vaginal mass during pregnancy is a concern whether it is malignancy or large vaginal varicosities that may put the patient at risk of severe hemorrhage during childbirth. We concluded that the mass was large vaginal varicosities as there was no discernible etiology. A repeat cesarean section was recommended due to the risk of hemorrhage during childbirth. For long-term management, close observation postpartum was recommended. Spontaneous resolution is a potential outcome and this is what our patient experienced. Without an underlying etiology, supportive measures are the best options.

The demand for decorative tattoos is steadily growing worldwide, and in the US it is estimated that up to 24% of adults has one or more tattoos. Subsequently, the number of tattoo-related complications is increasing. Among these, lymphoproliferative disorders play a minor but important role. The aim of this article is to arouse the awareness of plastic surgeons and dermatologists about this rare but serious complication and to stimulate stricter clinical control of their tattooed patients. We report a new case of tattoo-related cutaneous pseudolymphoma (CPL) and perform a review of the last 30 years of literature on the topic in PubMed. Apart from this new case, only 18 cases of CPL have been reported in PubMed so far. In contrast to the classic knowledge, the T cell was the predominant phenotype in 68% of cases. Red is confirmed to be the most involved ink. Topical and intralesional steroids, laser therapy, and surgery were used for treatment of CPL. Even if CPL is a very rare and benign complication, we should not forget that in rare cases pseudolymphoma may evolve into a true lymphoma. Diagnosis is still difficult and is based on anamnestic, clinical, and histopathological data. From the review of the literature, the T cell predominance suggests a reclassification of tattoo-induced CPL and there is not a gold standard treatment yet. Finally, once a pseudolymphoma is diagnosed, there must be a long follow-up because of the possibility to transform into a malignancy.

The purpose of our study was to assess the mechanical effect on tattoo seals and eye makeup caused by a spatial magnetic gradient in the magnetic resonance imaging (MRI) system. Seven kinds of tattoo seals and three kinds of eye makeup, i.e., mascara, eye shadow, and eyeliner were used. On a 3.0-Tesla MRI, we determined these deflection angles according to a method established by the American Society for Testing and Materials (ASTM) at the position that produced the greatest magnetically induced deflection. Eighty-five percent of the tattoo seals showed deflection angles greater than 45 degrees of the ASTM guidelines, and the mascara and eye shadow showed over 40 degrees. This was because these contained ferromagnetic pigments such as an iron oxide, but those translational forces were very small owing to slight mass. However, it is desirable that these should be removed before MRI examination to prevent secondary problems.

The nano tattoo represents a nascent technology designed to be implanted in the skin to provide continuous and reliable glucose detection for diabetics. Its potential benefits are compelling not only for its ability to prevent diabetic complications and decrease related social costs, but also for its ease of use and relative patient-user comfort. This Note aims to articulate a checklist of fundamental intellectual property, bioethical and system design issues that are appropriately considered in the pre-clinical, pre-commercialization phase of nano tattoo development. Early and regular consideration of these factors can increase the odds of a societally beneficial dissemination of this device by engaging relevant researcher, medical, patient-user and patient-advocate communities concerned with its appropriate application, as well as policymaking communities focused on effectively managing diabetes-related healthcare costs. The checklist of factors includes fundamental issues and is generally applicable to nanomedical inventions. This paper presents a comprehensive list of fundamental intellectual property, bioethical, and system design issues to be considered in the pre-commercialization phase of nanomedicine development, through the specific example of nano tattoo development. Nano tattoo is designed to be implanted in the skin to provide reliable glucose monitoring for diabetics, enabling enhanced prevention of complications and decreased socioeconomic costs.

Permanent tattooing due to blast injuries is a rare condition. Treatment with various different methods often yields unsatisfactory results. An innovative way to remove permanent traumatic tattoos is presented. A normal curettage blade is simply compressed with a pincer in order to create the new device. This V-shaped blade was used for surgical excision of the particles. No suture material or special dressing was used. Four patients with multiple explosive tattoos on the face were treated with the V-shaped knife. Due to the ease and speed of this method up to 300 particles were removed in one session. Histological analysis of the tissue samples showed deep dermal and subcutaneous particle location. At follow-up transient hypopigmentation but only minimal scarring was seen. Patients suffered less from itching, a chief complaint preoperatively, and aesthetic appearance of the facial skin was improved. In conclusion, treatment of traumatic tattoos with the V-shaped knife is effective, results in minimal scaring and restores the natural colour of the skin because the particle is completely removed. It is a promising method for treating multiple deep skin inclusions.

Postoperative Venous Thromboembolism in Patients Undergoing Endovenous Laser and Radiofrequency Ablation of the Saphenous Vein

2016-01-01

Objective: Endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) are safe and effective treatments for varicose veins caused by saphenous reflux. Deep venous thrombosis (DVT) and endovenous heat-induced thrombosis (EHIT) are known complications of these procedures. The purpose of this article is to investigate the incidence of postoperative DVT and EHIT in patients undergoing EVLA and RFA. Methods: The patients were assessed by clinical examination and venous duplex ultrasonography before operation and at 24–72 hours, 1 month, and 1 year follow-up after operation. Endovenous ablation (EVA) had been treated for 1026 limbs (835 patients) using an RFA; 1174 limbs (954 patients) using a 1470-nm wavelength diode laser with radial two-ring fiber (1470R); and 6118 limbs (5513 patients) using a 980-nm wavelength diode laser with bare-tip fiber (980B). Results: DVT was detected in 3 legs (0.3%) of RFA, 5 legs (0.4%) of 1470R, and 27 legs (0.4%) of 980B. One patient in three symptomatic DVT treated with 980B developed asymptomatic pulmonary embolus. In all, 31 of the 35 DVTs were confined to the calf veins. The incidence of EHIT classes 2 and 3 was 2.7% following RFA procedure, 6.7% after 1470R, and 7.5% after 980B. Conclusion: The incidence of EHIT following EVA was low, especially the RFA procedure. EHIT resolves within 2–4 weeks in most patients. DVT rates after EVA were compared with those published for saphenous vein stripping. (This is a translation of J Jpn Coll Angiol 2015; 55: 153–161.) PMID:28018495

Genetic material for polymerase chain reaction (PCR) and Southern blot analysis on transgenic mice is normally obtained by tail biopsy. Additionally, it may be necessary to tattoo the mice, as it is essential to have a good and permanent identification. The aim of this study was to evaluate the effects of amputating the tip of the tail to obtain a biopsy for genetic analysis and of ink tattooing on welfare in C57BL/6J mice, a strain often used as genetic background for transgenes. The behaviour of the animals, fluctuating asymmetry (FA, a measure of developmental instability) and the level of restitution in the remaining part of the tail were evaluated and used for an assessment of the impact of these procedures on the welfare of the animals. One group of mice was marked by tail tattooing at various ages. Another group of mice were tail amputated at 12 or 20 days of age. Body weight and FA were followed, and at the end of the experiment, the level of fear/anxiety was assessed using a light-dark box. In the group of tail-amputated animals observation of climbing behaviour and a beam walking test for balance was performed. Seven weeks after tail amputation, the animals were euthanized. The remaining part of the tail was evaluated histopathologically. Body weight, behaviour in the light-dark box and balance test results were not influenced by tail amputation or tattooing. FA was only transiently increased by tattooing. Climbing behaviour was reduced just after tail amputation at 20 days of age. No signs of neuromas were found in the amputated tails, but seven weeks after amputation a significant number of mice did not have fully regenerated glandular tissue and hair follicles in the tail. It is concluded that both tail amputation and tail tattooing seem to have minor short-term negative effects on welfare and that the tissues on the tail probably do not regenerate fully after amputation.

Varicose veins have been recognized as a risk factor for deep vein thrombosis (DVT). However, venous reflux has not carried the same correlation. This study evaluated the association between primary valvular reflux and DVT. We performed a nested case-control study with enrollment of outpatients presenting to the vascular laboratory with signs and symptoms of DVT. All patients had a complete bilateral venous duplex examination evaluating for DVT and superficial and deep venous valvular reflux. Eighty-seven patients with confirmed DVT on venous duplex were selected for the study group. The control group was randomly selected from the same cohort in a 4:1 ratio matched by age and gender (n = 348). Groups were compared for the prevalence of deep and superficial reflux. DVT outpatients were 4.7-times more likely to have primary valvular reflux than symptomatic controls (65.5% vs 29.0%; 95% confidence interval [CI], 2.8-7.7; P < .000001). Deep reflux was 2.1-times more prevalent (36.8% vs 21.6%; odds ratio, 2.12; 95% CI, 1.28-3.51; P = .005) and superficial reflux was 4.6-times more prevalent (43.7% vs 14.4%; odds ratio, 4.62; 95% CI, 2.75-7.77; P < .0000001) in DVT patients than in controls. DVT patients were also 2.1-times more likely to have combined deep and superficial reflux than non-DVT patients (13.8% vs 6.6%, 95% CI, 1.08-4.75; P = .044). The prevalence of primary valvular reflux in patients with DVT is significantly higher than expected. Reflux may be considered as a novel risk factor for DVT. Two-thirds of patients with DVT have pre-existent primary chronic venous disease, which is likely to contribute to post-thrombotic morbidity. Copyright © 2016 Society for Vascular Surgery.

Laser treatment represents an attractive option to other methods of vessel diseases especially varicose veins. A long pulse (30~50ms) 532nm laser (Fig.1) is used in our experiments with the pulse duration matching the thermal relaxation time of the vessels and the green laser matching the absorption spectrum peak of the blood. Laser irradiates nude vein vessels directly or exterior skin to finish operation faster and to acquire the practical data for upper enteron varicose vein treatment in several animal experiments performed in vivo. The 5J-energy pulse allows us to finely occlude rabbit or dog"s vein vessels up to 2 mm in diameter when irradiating them off external skin (Fig.2). Blood vessels are occluded at once and later biopsy specimens show the immediate and long-term lasting occlusion effect. While irradiating vessels directly (Fig.3), the vessels are usually irradiated to perforate, detailed causes are still under investigation. Animal experiments show long pulse green laser therapy is a safe and effective solution to the vein"s occlusion, which promises such laser with high energy of each pulse and 30~50 ms duration is an ideal candidate for vessel diseases treatment.

Extrahepatic portal vein obstruction, although rare in children, is a significant cause of portal hypertension (PHT) leading to life-threatening gastrointestinal bleeding in the pediatric age group. PHT may also lead to other complications such as hyperesplenism, cholangyopathy, ascites, and even hepatopulmonary syndrome and portopulmonary hypertension that may require organ transplantation. Herein we report the case of an asymptomatic 11-month-old infant wherein a hepatomegaly and cavernous transformation of the portal vein was detected by liver ultrasound. Neither signs of thrombosis in arteriovenous system, nor affectation of biliary tract were identified in the magnetic resonance imaging study. A significant enlargement of the caudate lobe of the liver was reported. No risk factors were detected. The differential diagnosis performed was extensive. Inherited thrombophilia and storage disorders were especially considered. Liver biopsy was normal. Upper gastrointestinal esophagogastroduodenoscopy detected two small varicose cords on the distal third of the esophagus. Finding a cavernous transformation of the portal vein with evidence of collateral circulation in such an early age is a challenging condition for professionals, since PHT may lead to severe complications during childhood and can compromise growth and development. Evidence-based guidelines for the management of PHT in adults have been published. However, follow-up and treatment of pediatric patients have not yet been standardized. Moreover, management of PHT in infants faces particular difficulties such as technical restrictions that could hinder their treatment. PMID:27504083

During laser treatment for tattoo removal, pigment chromophores absorb laser energy, resulting in fragmentation of the ink particles via selective photothermolysis. The present study aimed to outline macroscopic laser-tattoo interactions in tissue-mimicking (TM) phantoms treated with picosecond- and nanosecond-domain lasers. Additionally, high-speed cinematographs were captured to visualize time-dependent tattoo-tissue interactions, from laser irradiation to the formation of photothermal and photoacoustic injury zones (PIZs). In all experimental settings using the nanosecond or picosecond laser, tattoo pigments fragmented into coarse particles after a single laser pulse, and further disintegrated into smaller particles that dispersed toward the boundaries of PIZs after repetitive delivery of laser energy. Particles fractured by picosecond treatment were more evenly dispersed throughout PIZs than those fractured by nanosecond treatment. Additionally, picosecond-then-picosecond laser treatment (5-pass-picosecond treatment + 5-pass-picosecond treatment) induced greater disintegration of tattoo particles within PIZs than picosecond-then-nanosecond laser treatment (5-pass-picosecond treatment + 5-pass-nanosecond treatment). High-speed cinematography recorded the formation of PIZs after repeated reflection and propagation of acoustic waves over hundreds of microseconds to a few milliseconds. The present data may be of use in predicting three-dimensional laser-tattoo interactions and associated reactions in surrounding tissue.

Stirn, A

At present tattoos and piercings can no longer be regarded as destructive acts of self mutilation practized by fringe groups. Body modifications (BMs) are found in virtually all preindustrial cultures and have their roots in ancient myths and magical rituals. The prevalence of tattoos and piercings in the German population is 8.5% and 6.8%, respectively. Unemployed young men and young women who do not live in a firm partnership show particularly high prevalences. The incidence of BMs correlates positively with the personality trait "sensation seeking", particularly in young women. BMs often serve to express individuality and identity, and they also reflect changed attitude towards the human body and body art as well as following fashion trends. However, BMs can also provide valuable diagnostic indications for identity search and risk taking behaviour.

The increasing prevalence of tattoos provoked safety concerns with respect to particle distribution and effects inside the human body. We used skin and lymphatic tissues from human corpses to address local biokinetics by means of synchrotron X-ray fluorescence (XRF) techniques at both the micro (μ) and nano (ν) scale. Additional advanced mass spectrometry-based methodology enabled to demonstrate simultaneous transport of organic pigments, heavy metals and titanium dioxide from skin to regional lymph nodes. Among these compounds, organic pigments displayed the broadest size range with smallest species preferentially reaching the lymph nodes. Using synchrotron μ-FTIR analysis we were also able to detect ultrastructural changes of the tissue adjacent to tattoo particles through altered amide I α-helix to β-sheet protein ratios and elevated lipid contents. Altogether we report strong evidence for both migration and long-term deposition of toxic elements and tattoo pigments as well as for conformational alterations of biomolecules that likely contribute to cutaneous inflammation and other adversities upon tattooing.

The number of tattooed persons has been continuously increasing in the last few years, particularly in the younger population. At the same time, the possibility of purchasing tattoo inks online is easier than ever worldwide. Consumers are not always sufficiently aware of the possible health problems associated with this 'cool fashion' if hygiene conditions are not respected and/or if the injected mixtures contain dangerous chemicals. Concerns about the possible health risks associated with such practices arise from the absence of a clear legislative framework, the lack of proper risk assessment of the chemicals used, and non-harmonised or missing hygiene and purity requirements, among other factors. There is a general consensus among all active stakeholders that EU harmonised rules would help to ensure a consistent high level of protection of consumers across the EU. © 2015 S. Karger AG, Basel.

Multiple treatments of resistant tattoos often result in fibrosis and visible textural changes that lessen response to subsequent treatments. The aim of this study is to evaluate the influence of beam profile and spot size on clearance rates and side effects in the setting of resistant tattoos. Thirty-six professional, black tattoos (32 patients) were treated unsuccessfully with a Q-switched Nd:YAG laser (MedLite C3, HoyaConBio Inc., Fremont, CA). Because of therapy resistance all tattoos were re-treated using a new generation Nd:YAG laser (MedLite C6, HoyaConBio Inc.). Maximum energy fluence (E (max)), mean energy fluence, mean spot size, level of clearance, side effects and beam profile (irradiance distribution) of both laser systems were assessed and evaluated in a retrospective study. All tattoos were previously treated with the C3 laser at 1,064 nm using a mean E(max) of 5.8+/-0.8 J/cm(2) (range 3.8-7.5 J/cm(2)) as compared with a mean E(max) of 6.4+/-1.6 J/cm(2) (range 3.2-9.0 J/cm(2)) during the C6 treatment course. Corresponding spot sizes were larger during C6 treatments as compared with C3 (5.0+/-0.9 and 3.6+/-0.2 mm, respectively). The C6 laser had a "flat top" and homogenous profile regardless of the spot size. For the C3 laser the beam shape was "Gaussian," and the homogeneity was reduced by numerous micro-spikes and micro-nadirs. After the C6 treatment course 33.3% of the tattoos showed clearance of grade 1 (0-25%), 16.7% of grade 2 (26-50%), 16.7% of grade 3 (51-75%), 30.5% of grade 4 (76-95%), 2.8% of grade 5 (96-100%). The total rate of side effects due to C6 treatment was 8.3% in all tattoos (hyperpigmentation 5.6%, hypopigmentation 2.7%, textural changes/scars 0%). This clinical study documents for the first time the impact of a 1,064-nm Nd:YAG laser with a more homogenous beam profile and a larger spot size on the management of resistant tattoos. Only a few treatment sessions were necessary to achieve an additional clearance with a low rate of

Since laser treatment of tattoos is the favored method for the removing of no longer wanted permanent skin paintings, analytical, biokinetics and toxicological data on the fragmentation pattern of commonly used pigments are urgently required for health safety reasons. Applying dynamic headspace-gas chromatography with mass spectrometric detection (DHS-GC/MS) and comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GCxGC-ToF-MS), we identified 1,2-benzene dicarbonitrile, benzonitrile, benzene, and the poisonous gas hydrogen cyanide (HCN) as main fragmentation products emerging dose-dependently upon ruby laser irradiation of the popular blue pigment copper phthalocyanine in suspension. Skin cell viability was found to be significantly compromised at cyanide levels of ≥1 mM liberated during ruby laser irradiation of >1.5 mg/ml phthalocyanine blue. Further, for the first time we introduce pyrolysis-GC/MS as method suitable to simulate pigment fragmentation that may occur spontaneously or during laser removal of organic pigments in the living skin of tattooed people. According to the literature such regular tattoos hold up to 9 mg pigment/cm(2) skin.

Q-switched lasers are conventionally used for the treatment of black tattoo. However, they require multiple sittings, and the response may be slow due to competing epidermal pigment in dark skin. To compare the efficacy of Q-switched Nd:YAG laser alone with its combination with ultrapulse CO 2 for the removal of black tattoo. Sixty patients with black tattoo were randomized into two groups viz., group A and group B. Group A was treated with QS Nd:YAG laser (1064 nm) alone, and group B received combination of ablative ultrapulse CO 2 followed by fixed-dose QS Nd:YAG laser (1064 nm), at 6-week interval for a maximum of 6 sittings. After each sitting, 3 independent physicians noted percentage of improvement that was evaluated using visual analogue scale (VAS) and grading system for tattoo ink lightening (TIL). Combination laser (group B) showed statistically significant improvement in mean VAS score in the last 2 noted visits as compared to 1st session (p < 0.007, p < 0.001) and TIL mean score in last three noted visits as compared to 1st session (p < 0.008, p < 0.020, and p < 0.004). There was no statistically significant difference in the side effect profile of both the groups. For refractory professional tattoos, combination of ultrapulse CO 2 laser and QS Nd:YAG laser is superior to QS Nd:YAG laser alone.

Blue or black tattoos were observed in five patients who had received several intradermal injections (of a lidocaine solution or of a triamcinolone acetonide suspension) with the Dermo-Jet. A histological examination revealed the presence of black masses, rounded or elongated, different in size, distributed throughout dermal tissue. Additionally, conglomerates of black grains in the cytoplasm of histiocytes and of pericytes are precisely observed in semi-thin sections. It has been proved by several investigations that these foreign particles are not of metallic nature. It can be concluded from electron microscopic studies that the particles are fragments of black rubber, from the upper joint of the reservoir. Indeed, some rubber fragments are leached into the reservoir. Some of these are passing through the wire-mesh filter of the nozzle (with the solution or the suspension) when injections are made. Therefore, they are injected intradermally and are permanently tattooing the skin.

Variability of MMP/TIMP and TGF-β1 Receptors throughout the Clinical Progression of Chronic Venous Disease.

2017-12-21

Chronic venous disease (CVeD) is a prevalent condition with a significant socioeconomic burden, yet the pathophysiology is only just beginning to be understood. Previous studies concerning the dysregulation of matrix metalloproteinases (MMPs) and their inhibitors (tissue inhibitors of metalloproteinases (TIMPs)) within the varicose vein wall are inconsistent and disregard clinical progression. Moreover, it is highly plausible that MMP and TIMP expression/activity is affected by transforming growth factor (TGF)-β1 and its signaling receptors (TGFβRs) expression/activity in the vein wall. A case-control study was undertaken to analyze genetic and immunohistochemical differences between healthy ( n = 13) and CVeD (early stages: n = 19; advanced stages: n = 12) great saphenous vein samples. Samples were grouped based on anatomic harvest site and subjected to quantitative polymerase chain reaction for MMP1 , MMP2 , MMP8 , MMP9 , MMP12 , MMP13 , TIMP1 , TIMP2 , TIMP3 , TIMP4 , TGFβR1 , TGFβR2 , and TGFβR3 gene expression analysis, and then to immunohistochemistry for immunolocalization of MMP2, TIMP2, and TGFβR2. Decreased gene expression of MMP12 , TIMP2 , TIMP3 , TIMP4 , and TGFβR2 was found in varicose veins when compared to controls. Regarding CVeD clinical progression, two facts arose: results across anatomical regions were uneven; decreased gene expression of MMP9 and TGFβR3 and increased gene expression of MMP2 and TIMP3 were found in advanced clinical stages. Most immunohistochemistry results for tunica intima were coherent with qPCR results. In conclusion, decreased expression of TGFβRs might suggest a reduction in TGF-β1 participation in the MMP/TIMP imbalance throughout CVeD progression. Further studies about molecular events in the varicose vein wall are required and should take into consideration the venous anatomical region and CVeD clinical progression.

Objectives The aim of this study was to describe the changes of deep vein reflux after radiofrequency ablation for great saphenous vein incompetence. Method The data on 139 limbs which were treated with radiofrequency ablation for great saphenous vein incompetence were prospectively collected and reviewed. Results Deep vein reflux was present in 43 of 139 limbs (30.9%). There were no significant differences in the rate of successful closure, the incidence of procedure-related complications, and the improvements of symptoms and quality of life between the limbs with or without deep vein reflux. With a mean follow-up of 5.9 months, the peak reflux velocity and duration of reflux were improved in all limbs with deep vein reflux and it was completely corrected in 13 limbs (30.2%) after radiofrequency ablation. Conclusions The presence of deep vein reflux does not affect the treatment outcomes of radiofrequency ablation for great saphenous vein incompetence and is improved in all patients. Deep vein reflux is not a barrier to performing radiofrequency ablation.

The feasible application of double-layered skin phantoms was evaluated to identify artificial blood flow with a Doppler optical coherence tomography (DOCT) system for laser tattoo treatments. Polydimethylsiloxane (PDMS) was used to fabricate the artificial phantoms with flow channels embedded. A double-integrating sphere system with an inverse adding-doubling method quantified both the absorption and the reduced scattering coefficients for epidermis and dermis phantoms. Both OCT and caliper measurements confirmed the double-layered phantom structure (epidermis = 136 ± 17 µm vs. dermis = 3.0 ± 0.1 mm). The DOCT method demonstrated that high flow rates were associated with high image contrast, visualizing the position and the shape of the flow channel. Application of the channel-embedded skin phantoms in conjunction with DOCT can be a reliable technique to assess dynamic variations in the blood flow during and after laser tattoo treatments.

The use of natural or bioinspired materials to develop edible electronic devices is a potentially disruptive technology that can boost point-of-care testing. The technology exploits devices that can be safely ingested, along with pills or even food, and operated from within the gastrointestinal tract. Ingestible electronics can potentially target a significant number of biomedical applications, both as therapeutic and diagnostic tool, and this technology may also impact the food industry, by providing ingestible or food-compatible electronic tags that can "smart" track goods and monitor their quality along the distribution chain. Temporary tattoo-paper is hereby proposed as a simple and versatile platform for the integration of electronics onto food and pharmaceutical capsules. In particular, the fabrication of all-printed organic field-effect transistors on untreated commercial tattoo-paper, and their subsequent transfer and operation on edible substrates with a complex nonplanar geometry is demonstrated. © 2018 WILEY-VCH Verlag GmbH & Co.

Psoriasis has a profound negative effect on quality of life that is often underappreciated by health care professionals and the public. We sought to assess the perception of the burden of psoriasis relative to other medical conditions in first-year medical students, and to determine if wearing a temporary tattoo simulating psoriasis during a teaching exercise would change their perceptions. Participants completed a questionnaire assessing their perception of the impact of psoriasis and other common medical conditions (visual analog scale). Participants then wore a temporary tattoo of a psoriatic lesion for 24 hours and completed the same questionnaire after this exercise. Of 91 students approached, 61 completed the study. At baseline, psoriasis (mean = 23.6) and eczema (mean = 23.3) were perceived as having the lowest physical burden of diseases queried (P < .0001), whereas the mental impact of psoriasis was scored comparably with arthritis, heart disease, and diabetes (mean = 45.1-56.7), but lower than cancer (mean = 82.2) and depression (mean = 93.8). After the exercise, the perception of the impact of eczema (physical: mean = 37.3, P < .0001; mental: mean = 66.6, P = .0005) and psoriasis (physical: mean = 37.8, P = .0014; mental: mean = 68.6, P = .0293) was significantly increased. The exercise did not simulate the chronic nature of psoriasis or the scaling and pruritic characteristics of psoriatic lesions. The survey instrument used to assess empathy has not been previously validated and statistical analysis was limited by small sample size and the absence of a control group. Temporary tattoos are a novel and effective method of teaching medical students about the psychological burden of psoriasis. Copyright © 2011 American Academy of Dermatology, Inc.

To compare the half-life of STD and polidocanol air-based foams and the damage they inflict upon human great saphenous vein in an in-vitro model. The time for the volume of 3% STD and polidocanol foams to reduce by 10% (T(90)) and 50% (T(50)) was recorded in an incubator at 37 °C. Segments of proximal GSV harvested during varicose vein surgery were filled with foam for 5 or 15 min. Histological analysis determined percentage endothelial cell loss and depth of media injury. Median (±IQR) T(90) and T(50) for polidocanol were 123.3 s (111.7-165.6) and 266.3 s (245.6-383.1) versus 102.03 s (91.1-112) and 213.13 s (201-231.6) for STD (T(90)p = 0.008, T(50)p = 0.004). Median endothelial loss with polidocanol was; 63.5% (62.2-82.8) and 85.9% (83.8-92.5) versus 86.3% (84.8-93.7) and 97.64% (97.3-97.8) for STD after 5 and 15 min (p = 0.076 and p = 0.009). The median depth and % media thickness injured were 0 μm (0-0 μm) and 0% for both assessments with polidocanol versus 37.4 μm (35.3-45.8 and 43.4 μm (42.1-46.7) and 3.5% (3.1-3.6) and 5.3% (3.7-6.0) after 5 and 15 min for STD (p < 0.01 for all comparisons). Although polidocanol foam shows greater stability than STD foam perhaps remaining in the vein for longer, endothelial cell loss and damage to the media were significantly greater with STD.

The ability of remotely tagging tissues in a controlled and three-dimensional manner during preoperative imaging could greatly help surgeons to identify targets for resection. The authors' objective is to selectively and noninvasively deposit markers under image guidance for such internal tattooing. This study describes the production of new ultrasound-inducible droplets carrying large payloads of fluorescent markers and the in vivo proof of concept of their remote and controlled deposition via focused ultrasound. The droplets are monodispersed multiple emulsions produced in a microfluidic system, consisting of aqueous fluorescein in perfluorocarbon in water. Their conversion (either by vaporization or cavitation) is performed remotely using a clinical ultrasonic imaging probe. When submitted to 5 MHz imaging pulses, the droplets vaporize in vitro at 1.4 MPa peak-negative pressure and eject their content. After several seconds, a brightly fluorescent spot (0.5 mm diameter) is observed at the focus of the transducer. Experiments in the chorioallantoique membrane of chicken eggs and chicken embryo demonstrate that the spot is stable and is easily seen by naked eye. These ultrasound-inducible multiple emulsions could be used to deliver large amounts of contrast agents, chemotherapy, and genetic materials in vivo using a conventional ultrasound scanner.

The picosecond Alexandrite laser has shown increased efficacy in tattoo removal in comparison to Q-switched lasers. However, bulla formation is a well-known and expected side effect of this novel treatment and causes patient discomfort. To analyze the incidence of bulla formation after tattoo treatment using the combination of the picosecond Alexandrite laser and fractionated CO2 ablation. This is a retrospective chart review to determine the incidence of bulla formation after laser tattoo removal in 95 patients who were treated with either with the picosecond Alexandrite laser alone or in combination with fractional CO2 ablation. Twenty-six patients (32%) treated with the picosecond laser alone experienced blistering, whereas none of the patients treated with the combination of the picosecond laser and fractionated CO2 ablation experienced blistering. The difference in incidence of bulla formation between the 2 groups was found to be statistically significant (p < .05). This study shows a significant decrease in bulla formation associated with tattoo treatment when fractionated CO2 ablation is added to the picosecond Alexandrite laser, which is consistent with observations from a previous case series. This is important because decreasing extensive blistering likely results in increased patient satisfaction and willingness to return for future treatments.

62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral circulation was diminished. Pancreaticoduodenectomy (PD) and superior mesenteric portal vein (SMPV) confluence resection were performed; A saphenous vein interposition graft thrombosed immediately. The splenic vein remnant was distended and adjacent to the stump of the portal vein. Harvesting an internal jugular vein graft required extra time and using a synthetic graft posed a risk of graft thrombosis or infection. As a result, we chose to perform a direct anastomosis of the portal and splenic vein in a desperate situation. The anastomosis decompressed the mesenteric venous system, so we then ligated the SMV. The patient had an uneventful postoperative course, except transient ascites. She redeveloped ascites more than one year later. At that time a PET scan showed bilateral lung and right femur metastatic disease. She expired 15 months after PD. The lessons we learned are (1) Before SMPV confluence resection, internal jugular vein graft should be ready for reconstruction. (2) Synthetic graft is an alternative for internal jugular vein graft. (3) Direct portal vein to SMV anastomosis can be achieved by mobilizing liver. (4) It is possible that venous collaterals secondary to SMV tumor obstruction may have allowed this patient's post-operative survival.

The purpose of this paper is to estimate the efficacy of Nd:Yag laser and IPL combined action for the treatment of deep (up to 5 mm) and large (up to 3 mm in diameter) reticular varicosity of the lower extremity. A group of 38 subjects (2 male and 36 female) aged from 34 to 65 years were treated for deep reticular varicosity of the legs. All patients underwent various clinical analyses in order to evaluate and exclude pre-existing cardiovascular pathology, coagulation disorders as well as pathology due to saphena incontinence. Also, for the first three months they underwent ambulatory specialistic treatments at 21-days intertreatment interval. A reduction of venous network of 80-90% after 2 treatment sessions with Nd:Yag laser was obtained in 84% of subjects. Successive 3 treatment sessions with IPL have achieved complete vanishing of the treated venous network in 36 patients (95%). A combined action of Nd:Yag laser and IPL has demonstrated its particular efficacy in non-invasive treatment of deep and extensive reticolar varicosity of the lower extremity, considering also that it is well tolerated by patients and applicable in each single case on out patient basis.

Effectively managing pain is vital for the well-being and satisfaction of patients undergoing dermatologic treatments involving lasers. This study investigates the potential outcome of using muscle relaxation techniques to reduce pain among people having their tattoos removed with laser treatment. This study consists of 56 participants (mean age 18.1 ± 2.1 years) that had tattoos removed using the principle of selective photothermolysis. These participants underwent muscle relaxation before receiving the laser treatment. Their peripheral skin temperatures (PST) were measured both at the beginning and the end of the muscle relaxation period. Then, the Beck Anxiety Inventory was applied to evaluate anxiety levels. Once the laser treatment was completed, pain levels were measured using a visual analogue scale. A total of 125 person-sessions of laser treatment and psychometric assessments were performed in this study. The muscle relaxation method significantly increased the PST of the participants while reducing the levels of anxiety and pain throughout the course of the laser treatment procedure. The PST, anxiety scores, and pain scores all showed significant correlations with one another. According to the results obtained, this study proposes that muscle relaxation techniques be considered possibly auxiliary treatment options for individuals having tattoos removed through laser treatment. Additional studies with a comparison group and a larger sample size are required in the future to confirm the effectiveness of such intervention.

Temporary Black Henna Tattoos and Sensitization to para-Phenylenediamine (PPD): Two Paediatric Case Reports and a Review of the Literature.

PubMed

Panfili, Elisa; Esposito, Susanna; Di Cara, Giuseppe

2017-04-14

Background : The use of temporary henna tattoos has increased dramatically in recent years, especially in children and adolescents. To obtain a darker colour and prolong the life of the tattoo, red henna, a plant-derived substance, is typically added to para -phenylenediamine (PPD). The mixture is called temporary black henna tattoo (TBHT). Because of its molecular characteristics, PPD can induce skin sensitization that may cause various clinical manifestations with successive exposures, among which the most common is allergic contact dermatitis (ACD). This report describes two paediatric cases of PPD sensitization and ACD after the exposure to TBHT and summarizes the literature on this emerging clinical problem. Case Presentation : We describe two cases of childhood-onset ACD that occurred 2 and 10 days, respectively, after the application of a TBHT during the summer holidays. Patch tests showed an evident positive response to 1% PPD in both cases. Sensitization to PPD occurred in the first case because a previous henna tattoo did not result in overt symptoms; in the second case, the reaction occurred after the same tattoo was retouched. In both cases, hypopigmentation persisted and both the patients and their families were advised to avoid further contact with PPD-containing materials and substances that could lead to cross-reactions. Conclusions : Sensitization to PPD is a growing phenomenon in children. The most common cause appears to be exposure to TBHT in which PPD might be present at unknown or high concentrations. Once sensitization occurs, patients may experience severe clinical symptoms which can present with a persistent hypopigmentation when they are re-exposed to substances that contain or cross-react with PPD. Given the widespread use of PPD, TBHT could adversely affect the daily life of paediatric patients; thus, for this reason, this practice as a fashion accessory must be discouraged. In addition, it is extremely important to provide scientific

A continuously variable beam-diameter, high-fluence, Q-switched Nd:YAG laser for tattoo removal: comparison of the maximum beam diameter to a standard 4-mm-diameter treatment beam.

Laser beam diameter affects the depth of laser penetration. Q-switched lasers tend to have smaller maximum spot sizes than other dermatologic lasers, making beam diameter a potentially more significant factor in treatment outcomes. To compare the clinical effect of using the maximum-size treatment beam available for each delivered fluence during laser tattoo removal to a standard 4-mm-diameter treatment beam. Thirteen tattoos were treated in 12 subjects using a Q-switched Nd:YAG laser equipped with a treatment beam diameter that was adjustable in 1 mm increments and a setting that would enable the maximally achievable diameter ("MAX-ON" setting) with any fluence. Tattoos were randomly bisected and treated on one side with the MAX-ON setting and on the contralateral side with a standard 4-mm-diameter spot ("MAX-OFF" setting). Photographs were taken 8 weeks following each treatment and each half-tattoo was evaluated for clearance on a 10-point scale by physicians blinded to the treatment conditions. Tattoo clearance was greater on the side treated with the MAX-ON setting in a statistically significant manner following the 1st through 4th treatments, with the MAX-OFF treatment site approaching the clearance of the MAX-ON treatment site after the 5th and 6th treatments. This high-energy, Q-switched Nd:YAG laser with a continuously variable spot-size safely and effectively removes tattoos, with greater removal when using a larger spot-size. © 2013 Wiley Periodicals, Inc.

2014-10-01

To assess the deep vein thrombosis risk of the treatment of the small saphenous veins depending on the anatomical pattern of the veins. A multicenter, prospective and controlled study was carried out in which small saphenous vein trunks were treated with ultrasound-guided foam sclerotherapy. The anatomical pattern (saphenopopliteal junction, perforators) was assessed by Duplex ultrasound before the treatment. All patients were systematically checked by Duplex ultrasound 8 to 30 days after the procedure to identify a potential deep vein thrombosis. Three hundred and thirty-one small saphenous veins were treated in 22 phlebology clinics. No proximal deep vein thrombosis occurred. Two (0.6%) medial gastrocnemius veins thrombosis occurred in symptomatic patients. Five medial gastrocnemius veins thrombosis and four cases of extension of the small saphenous vein sclerosis into the popliteal vein, which all occurred when the small saphenous vein connected directly into the popliteal vein, were identified by systematic Duplex ultrasound examination in asymptomatic patients. Medial gastrocnemius veins thrombosis were more frequent (p = 0.02) in patients with medial gastrocnemius veins perforator. A common outlet or channel between the small saphenous vein and the medial gastrocnemius veins did not increase the risk of deep vein thrombosis. Deep vein thrombosis after foam sclerotherapy of the small saphenous vein are very rare. Only 0.6% medial gastrocnemius veins thrombosis occurred in symptomatic patients. However, the anatomical pattern of the small saphenous vein should be taken into account and patients with medial gastrocnemius veins perforators and the small saphenous vein connected directly into the popliteal vein should be checked by Duplex ultrasound one or two weeks after the procedure. Recommendations based on our everyday practice and the findings of this study are suggested to prevent and treat deep vein thrombosis. © The Author(s) 2013 Reprints and

Ligation of superior mesenteric vein and portal to splenic vein anastomosis after superior mesenteric-portal vein confluence resection during pancreaticoduodenectomy – Case report

62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral circulation was diminished. Pancreaticoduodenectomy (PD) and superior mesenteric portal vein (SMPV) confluence resection were performed; A saphenous vein interposition graft thrombosed immediately. The splenic vein remnant was distended and adjacent to the stump of the portal vein. Harvesting an internal jugular vein graft required extra time and using a synthetic graft posed a risk of graft thrombosis or infection. As a result, we chose to perform a direct anastomosis of the portal and splenic vein in a desperate situation. The anastomosis decompressed the mesenteric venous system, so we then ligated the SMV. The patient had an uneventful postoperative course, except transient ascites. She redeveloped ascites more than one year later. At that time a PET scan showed bilateral lung and right femur metastatic disease. She expired 15 months after PD. Conclusion The lessons we learned are (1) Before SMPV confluence resection, internal jugular vein graft should be ready for reconstruction. (2) Synthetic graft is an alternative for internal jugular vein graft. (3) Direct portal vein to SMV anastomosis can be achieved by mobilizing liver. (4) It is possible that venous collaterals secondary to SMV tumor obstruction may have allowed this patient's post-operative survival. PMID:25568802

Extrahepatic portal vein obstruction and portal vein thrombosis in special situations: Need for a new classification.

2015-01-01

Extrahepatic portal vein obstruction is a vascular disorder of liver, which results in obstruction and cavernomatous transformation of portal vein with or without the involvement of intrahepatic portal vein, splenic vein, or superior mesenteric vein. Portal vein obstruction due to chronic liver disease, neoplasm, or postsurgery is a separate entity and is not the same as extrahepatic portal vein obstruction. Patients with extrahepatic portal vein obstruction are generally young and belong mostly to Asian countries. It is therefore very important to define portal vein thrombosis as acute or chronic from management point of view. Portal vein thrombosis in certain situations such as liver transplant and postsurgical/liver transplant period is an evolving area and needs extensive research. There is a need for a new classification, which includes all areas of the entity. In the current review, the most recent literature of extrahepatic portal vein obstruction is reviewed and summarized.

The practice of tattooing and piercing has expanded in western society. In order to verify young adults' knowledge of the risk and practices related to body art, an investigation was conducted among freshmen of the University of Bari in the region of Apulia, Italy. The study was carried out in the Academic Year 2009-2010 through an anonymous self-administered written questionnaire distributed to 1.656 freshmen enrolled in 17 Degree Courses. Of the 1.598 students included in the analysis, 78.3% believe it is risky to undergo piercing/tattoo practices. AIDS was indicated as a possible infection by 60.3% of freshmen, hepatitis C by 38.2%, tetanus by 34.3% and hepatitis B by 33.7% of the sample. 28.1% of freshmen were not aware that there are also non-infectious complications. 29% of the sample had at least one piercing or tattoo (this percentage does not include earlobe piercing in women). Of those with body art, the decision to undergo body art was made autonomously in 57.9% of the participants. 56.3% of freshmen undergoing body art had taken less than a month to decide. With regard to the reasons that led the sample to undergo body art, 28.4% were unable to explain it, 23.8% answered to improve their aesthetic aspect, 18.4% to distinguish themselves from others, 12.3% for fashion; 17.1% for other reasons. 25.4% of the sample declared that they had a piercing (79.8% female vs 20.2% male; ratio M/F 1:4.0). The average age for a first piercing was 15.3 years (range 10-27; SD ± 2.9). 9.6% of the sample declared that they have a tattoo (69.9% female vs 30.1% male; ratio M/F 1:2.3). The average age for a first tattoo was 17.5 years (range 10-26, SD ± 2.4). Most of the freshmen knew about AIDS-related risks but not other potential risks. Body art is fairly common among young adults (especially women). The decision is often not shared with the family and is undertaken mostly without a specific reason or for the improvement of aesthetic aspect. Information about freshmen

Color Doppler is a technique which performs a real-time opacification of the vascular system with blue indicating reverse flow and red indicating forward flow (directional color coding). In venous pathology, the use of color Doppler improves significantly the anatomical evaluation of the inferior vena cava, the iliac vein, the deep femoral vein, and the sural system. Color Doppler facilitates the study of deep venous thrombosis (providing useful information to differentiate ancient from most recent thrombus) and also the study of post-thrombotic conditions (assessment of reverse flow, repermeation phenomena). Finally, color Doppler produces a better insight for the study of varicose veins, especially with regard to mapping, identification of communicante veins, and study of the external saphenous vein.

There are few reported cases of cavernous transformation of the portal vein (CTPV) in adults. We present a case of a 58 year-old male who was found to have this complication due to portal vein thrombosis (PVT). A 58-year old African American male with chronic alcohol and tobacco use presented with a 25-day history of weakness, generalized malaise, nausea and vomiting associated with progressively worsening anorexia and weight loss. The patient was admitted for severe anemia in conjunction with abnormal liver function tests and electrolyte abnormalities, and to rule out end stage liver disease or hepatic malignancy. The work-up for anemia showed no significant colon abnormalities, cholecystitis, liver cirrhosis, or liver abnormalities but could not rule out malignancy. An esophageogastroduodenoscopy (EGD) was suspicious for a mass compressing the stomach and small bowel. After further work-up, the hepatic mass has been diagnosed as a cavernous transformation of the portal vein (CTPV), a very rare complication of portal vein thrombosis (PVT). Cavernous Transformation of the Portal Vein (CTPV) is a rare and incurable complication of portal vein thrombosis (PVT) that should be considered as one of the differential diagnoses of a hepatic mass.

Venous thrombosis is common in older age, with an incidence of 0·5-1% per year in those aged >70 years. Stasis of blood flow is an important contributor to the development of thrombosis and may be due to venous insufficiency in the legs. The risk of thrombosis associated with clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, obtained with a standardized interview was assessed in the Age and Thrombosis Acquired and Genetic risk factors in the Elderly (AT-AGE) study. The AT-AGE study is a case-control study in individuals aged 70 years and older (401 cases with a first-time venous thrombosis and 431 control subjects). We calculated odds ratios (ORs) and corresponding 95% confidence intervals (CI) adjusted for age, sex and study centre. Varicose veins and leg ulcer were associated with a 1·6-fold (95% CI 1·2-2·3) and 3·3-fold increased risk of thrombosis (95% CI 1·6-6·7), respectively, while the risk was increased 3·0-fold (95% CI 2·1-4·5) in the presence of leg oedema. The risk of thrombosis was highest when all three risk factors occurred simultaneously (OR: 10·5; 95% CI 1·3-86·1). In conclusion, clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, are risk factors for venous thrombosis in older people. © 2015 John Wiley & Sons Ltd.

Mondor's disease of the penis following a long-haul flight.

Day, S; Bingham, J S

2005-07-01

Mondor's disease of the penis, otherwise known as superficial thrombophlebitis (STP) or thrombosis of the dorsal vein, is an under-reported benign condition, the aetiology of which is poorly understood. It is characterized by a sudden, indurated swelling of the vein, often occurring after vigorous sexual activity. We report a case of Mondor's disease occurring 24 h following a 15-h flight. This gentleman also reported a history of STP of his left lower limb varicose veins following a similar-length flight three years previously. In the absence of any other clear predisposing factor, we propose long-haul flight as an important factor contributing to the development of dorsal vein thrombosis.

Cosmetic tattoos contain titanium and ferric oxide and darken through reduction after Q-switched laser irradiation. The optimal treatment for removing these pigments remains unknown. To compare the effects of two Q-switched lasers and a short-pulse erbium-doped yttrium aluminum garnet (SP Er:YAG) laser to remove cosmetic tattoos in an animal model. Rats were tattooed using white, flesh-colored, and brown inks (4 bands of each color) on their backs. For each color, one band was left untreated, and one each was treated with a Q-switched neodymium-doped YAG laser, a Q-switched alexandrite laser, and a SP Er:YAG laser every 3 weeks until the pigments were clear. The two Q-switched lasers were equally effective; all three pigments darkened initially and then resolved gradually. Up to 20, 18, and 10 sessions were required to remove white, flesh-colored, and brown tattoos, respectively. Only six sessions were required with the SP Er:YAG laser. Minimal scarring was observed with all lasers. Skin biopsies confirmed pigment granule fragmentation after Q-switched laser treatment and a decrease in the amount of pigment after SP Er:YAG laser treatment. The SP Er:YAG laser was superior to the Q-switched lasers for removing cosmetic tattoos. © 2010 by the American Society for Dermatologic Surgery, Inc.

Invaginated axial saphenectomy by a semirigid stripper: perforate-invaginate stripping.

PubMed

Goren, G; Yellin, A E

1994-12-01

This study was designed to evaluate a recently introduced form of stripping of primary varicose veins by the technique of perforate-invaginate (PIN) stripping. One hundred twelve consecutive limbs presenting with 91 long and 21 short saphenous varicosities displaying saphenofemoral or saphenopopliteal junctional escapes with varying length of greater or lesser saphenous (axial) reflux underwent operation in 1 year. All surgeries were performed in an office setting with the patient receiving locoregional anesthetic with use of the invaginated PIN stripping in conjunction with tributary hook-stab avulsion. In the 112 procedures performed, there were no tract hematomas or dysesthesias caused by nerve damage. Postoperative morbidity was nonexistent, permitting all patients to resume normal daily occupational and sporting activities immediately. PIN stripping is an excellent method of invagination stripping. There is a minimal likelihood of vein tearing. Compared with conventional ankle-to-groin (or popliteal fossa) stripping, PIN stripping is minimally invasive, does not cause damage to structures around the vein, does not require convalescence, eliminates the need for a lengthy distal second incision, can be performed in an office setting with the patient receiving locoregional anesthetic, and is most cost-efficient.

veins (to have occurred in 25% of the cases). Of special interest was the finding that insufficiency of the ostial valve of the great saphenous vein, manifesting itself by a superficial vertical veno-venous reflux, was revealed only in two (6.25%) patients examined 12 months after the onset of the disease, which may be regarded as the third stage of the phlebohaemodynamic alterations. That low prevalence and no evidence of varicose transformation of superficial veins appear to suggest an important part they play in compensation of the venous outflow from the extremity affected.

Resection of the involved mesenteric-portal vein (MPV) is increasingly performed in pancreatoduodenectomy. The primary aim of this study is to assess the rate of R0 resection in transverse closure (TC) versus segmental resection with end-to-end (EE) closure and the secondary aims are to assess the short-term morbidity and long-term survival of TC versus EE. Patients undergoing pancreatoduodenectomy with MPV resection were identified from a prospectively database. The reconstruction technique were examined and categorized. Clinical, pathological, short-term and long-term survival outcomes were compared between groups. 110 patients underwent PD with MPV resection of which reconstruction was performed with an end-to-end technique in 92 patients (84%) and transverse closure technique in 18 patients (16%). Patients undergoing transverse closure tended to have had a shorter segment of vein resected (≤2 cm) compared to the end-to-end (83% vs. 43%; P = 0.004) with no difference in R0 rate. Short-term morbidity was similar. The median and 5-year survival was 30.0 months and 18% respectively for patients undergoing transverse closure and 28.6 months and 7% respectively for patients undergoing end-to-end reconstruction (P = 0.766). Without compromising the R0 rate, transverse closure to reconstruct the mesenteric-portal vein is shown to be feasible and safe in the setting when a short segment of vein resection is required during pancreatoduodenectomy. Synopsis - We describe a vein closure technique, transverse closure, which avoids the need for a graft, or re-implantation of the splenic vein when resection of the mesenteric-portal vein confluence is required during pancreatoduodenectomy.

Chronic venous disease (CVD) is a common and relevant problem affecting Western people. The role of estrogens and their receptors in the venous wall seems to support the major prevalence of CVD in women. The effects of the estrogens are mediated by three estrogen receptors (ERs): ERα, ERβ, and G protein-coupled ER (GPER). The expression of ERs in the vessel walls of varicose veins is evaluated. In this prospective study, patients of both sexes, with CVD and varicose veins undergoing open venous surgery procedures, were enrolled in order to obtain vein samples. To obtain control samples of healthy veins, patients of both sexes without CVD undergoing coronary artery bypass grafting with autologous saphenous vein were recruited (control group). Samples were processed in order to evaluate gene expression. Forty patients with CVD (10 men [25%], 30 women [75%], mean age 54.3 years [median 52 years, range 33-74 years]) were enrolled. Five patients without CVD (three men, two women [aged 61-73 years]) were enrolled as the control group. A significant increase of tissue expression of ERα, ERβ and GPER in patients with CVD was recorded (p < .01), which was also related to the severity of venous disease. ERs seem to play a role in CVD; in this study, the expression of ERs correlated with the severity of the disease, and their expression was correlated with the clinical stage.

Personal identification technology as security systems is developing rapidly. Traditional authentication modes like key; password; card are not safe enough because they could be stolen or easily forgotten. Biometric as developed technology has been applied to a wide range of systems. According to different researchers, vein biometric is a good candidate among other biometric traits such as fingerprint, hand geometry, voice, DNA and etc for authentication systems. Vein authentication systems can be designed by different methodologies. All the methodologies consist of matching stage which is too important for final verification of the system. Neural Network is an effective methodology for matching and recognizing individuals in authentication systems. Therefore, this paper explains and implements the Neural Network methodology for finger vein authentication system. Neural Network is trained in Matlab to match the vein features of authentication system. The Network simulation shows the quality of matching as 95% which is a good performance for authentication system matching.

Background Current consensus statements maintain that endoscopic vein harvesting (EVH) should be standard care in coronary artery bypass graft surgery, but vein quality and clinical outcomes have been questioned. The VICO trial (Vein Integrity and Clinical Outcomes) was designed to assess the impact of different vein harvesting methods on vessel damage and whether this contributes to clinical outcomes after coronary artery bypass grafting. Methods In this single-center, randomized clinical trial, patients undergoing coronary artery bypass grafting with an internal mammary artery and with 1 to 4 vein grafts were recruited. All veins were harvested by a single experienced practitioner. We randomly allocated 300 patients into closed tunnel CO2 EVH (n=100), open tunnel CO2 EVH (n=100), and traditional open vein harvesting (n=100) groups. The primary end point was endothelial integrity and muscular damage of the harvested vein. Secondary end points included clinical outcomes (major adverse cardiac events), use of healthcare resources, and impact on health status (quality-adjusted life-years). Results The open vein harvesting group demonstrated marginally better endothelial integrity in random samples (85% versus 88% versus 93% for closed tunnel EVH, open tunnel EVH, and open vein harvesting; P<0.001). Closed tunnel EVH displayed the lowest longitudinal hypertrophy (1% versus 13.5% versus 3%; P=0.001). However, no differences in endothelial stretching were observed between groups (37% versus 37% versus 31%; P=0.62). Secondary clinical outcomes demonstrated no significant differences in composite major adverse cardiac event scores at each time point up to 48 months. The quality-adjusted life-year gain per patient was 0.11 (P<0.001) for closed tunnel EVH and 0.07 (P=0.003) for open tunnel EVH compared with open vein harvesting. The likelihood of being cost-effective, at a predefined threshold of £20 000 per quality-adjusted life-year gained, was 75% for closed tunnel EVH

The management of cosmetic vein problems requires a very different approach than that for the majority of most other vascular disorders that occur in a vascular surgery practice. This article focuses on the business aspects of a cosmetic vein practice, with particular attention to the uniqueness of these issues. Managing patient expectations is critical to the success of a cosmetic vein practice. Maneuvering within the insurance can be difficult and frustrating for both the patient and the practice. Practices should use cost accounting principles to evaluate the success of their vein work. Vein surgery--especially if performed within the office--can undergo an accurate break-even analysis to determine its profitability.

Locating difficult veins for venepuncture and cannulation.

Vein location and assessment are essential to improve the success rates for vascular access. However, problems remain with first attempt success rates for peripheral cannulation and locating difficult veins. Practitioners may not be aware of developments in technology and aids to assist in the location and assessment of veins to achieve vascular access. This article provides an overview of two vein location aids that can be used to locate difficult veins: the IV-eye vein imager and the Vacuderm tourniquet. It discusses the patient factors that can increase the difficulty of vein assessment and location, and emphasises the importance of vessel health and preservation, and vein palpation. Practitioners should be experienced and skilled in the assessment of veins, and they are encouraged to revisit how they locate and assess veins.

Objective To systematically review all available English literature on mechanochemical endovenous ablation and to report on the anatomical, technical, and clinical success. Methods A systematic literature search was performed in PubMed, EMBASE, and the Cochrane Library on mechanochemical endovenous ablation for the treatment of insufficient great and/or small saphenous vein. Methodological quality of the included studies was evaluated using the MINORS score. The primary outcome measure was anatomical success, defined as closure of the treated vein on follow-up duplex ultrasound imaging. Secondary outcomes were technical and clinical success, and major complications defined as deep venous thrombosis, pulmonary embolisms or paresthesia. Results The literature search identified 759 records, of which 13 were included, describing 10 unique cohorts. A total of 1521 veins (1267 great saphenous vein and 254 small saphenous vein) were included, with cohort sizes ranging from 30 to 570 veins. The pooled anatomical success rate after short-term follow up was 92% (95% CI 90-94%) ( n = 1314 veins). After 6 and 12 months these numbers were 92% (95% CI 88-95%) ( n = 284) and 91% (95% CI 86-94%) ( n = 228), respectively. The long-term anatomical success rates at 2 and 3 years were 91% (95% CI 85-95%) ( n = 136) and 87% (95% CI 75-94%) ( n = 48), respectively. Major complications and especially nerve injury were very rare (≤ 0.2%). All studies were of moderate or good quality using the MINORS scoring scale. Conclusions Mechanochemical endovenous ablation using the ClariVein in combination with liquid sclerosant is associated with an anatomical success rate ranging from 87% to 92% and good clinical success. To date, no randomized controlled trials are available studying the anatomical success after mechanochemical ablation, compared to the endothermal ablation. The risk of major complications is very low after the procedure.

Femoral vein injury managed by in situ saphenous vein bypass : a case report.

Coppin, Th; Kuhnle, M

Injured veins of the lower limbs may cause massive haemorrhage requiring early control. Operative management of injured veins remains a controversial topic and reconstruction or ligation depends on venous and adjacent tissue damage. Nevertheless, venous reconstruction seems to reduce the complications of venous ligation. The case of a 33 year old women with a venous wound to the right groin is presented. Surgical management consisted of controlling the bleeding and venous revascularisation with an in situ saphenous vein bypass to substitute the injured femoral vein. The patient had an uneventful postoperative period without any complications. The case demonstrates this method of vascular venous repair is the preferable one. Copyright© Acta Chirurgica Belgica.

Arabidopsis thaliana Ei-5: Minor Vein Architecture Adjustment Compensates for Low Vein Density in Support of Photosynthesis.

PubMed

Stewart, Jared J; Polutchko, Stephanie K; Demmig-Adams, Barbara; Adams, William W

2018-01-01

An Arabidopsis thaliana accession with naturally low vein density, Eifel-5 (Ei-5), was compared to Columbia-0 (Col-0) with respect to rosette growth, foliar vein architecture, photosynthesis, and transpiration. In addition to having to a lower vein density, Ei-5 grew more slowly, with significantly lower rates of rosette expansion, but had similar capacities for photosynthetic oxygen evolution on a leaf area basis compared to Col-0. The individual foliar minor veins were larger in Ei-5, with a greater number of vascular cells per vein, compared to Col-0. This compensation for low vein density resulted in similar values for the product of vein density × phloem cell number per minor vein in Ei-5 and Col-0, which suggests a similar capacity for foliar sugar export to support similar photosynthetic capacities per unit leaf area. In contrast, the product of vein density × xylem cell number per minor vein was significantly greater in Ei-5 compared to Col-0, and was associated not only with a higher ratio of water-transporting tracheary elements versus sugar-transporting sieve elements but also significantly higher foliar transpiration rates per leaf area in Ei-5. In contrast, previous studies in other systems had reported higher ratios of tracheary to sieve elements and higher transpiration rate to be associated with higher - rather than lower - vein densities. The Ei-5 accession thus further underscores the plasticity of the foliar vasculature by illustrating an example where a higher ratio of tracheary to sieve elements is associated with a lower vein density. Establishment of the Ei-5 accession, with a low vein density but an apparent overcapacity for water flux through the foliar xylem network, may have been facilitated by a higher level of precipitation in its habitat of origin compared to that of the Col-0 accession.

Scattering Removal for Finger-Vein Image Restoration

Finger-vein recognition has received increased attention recently. However, the finger-vein images are always captured in poor quality. This certainly makes finger-vein feature representation unreliable, and further impairs the accuracy of finger-vein recognition. In this paper, we first give an analysis of the intrinsic factors causing finger-vein image degradation, and then propose a simple but effective image restoration method based on scattering removal. To give a proper description of finger-vein image degradation, a biological optical model (BOM) specific to finger-vein imaging is proposed according to the principle of light propagation in biological tissues. Based on BOM, the light scattering component is sensibly estimated and properly removed for finger-vein image restoration. Finally, experimental results demonstrate that the proposed method is powerful in enhancing the finger-vein image contrast and in improving the finger-vein image matching accuracy. PMID:22737028

To retrospectively evaluate the efficacy of an Alexandrite picosecond laser versus Nd:YAG nanosecond laser for removing blue-black eyeliner tattoos which have existed more than 10 years. A total of 40 patients were treated with an Alexandrite picosecond laser in our department from August 2015 to July 2017, with a fluence of 1.96-6.37J/cm 2 , spot size of 2.0-3.6 mm, and pulse width of 750 ps. Another 32 patients were treated with an Nd:YAG nanosecond laser, with a fluence of 2.80-7.00 J/cm 2 , spot size of 3 mm, and pulse width of 5-20 ns. All analysed patients completed at least one treatment and follow-up. The median number of treatment for all the patients was 1 (range, 1-4). After a single session, no difference was found between the two lasers for the eyeliner removal (p > 0.05). For the people who achieved an excellent response of tattoo clearance, there was still no difference between the two groups (p > 0.05). Transient side effects were observed in two groups, but neither group had significant adverse reactions. To treat blue-black Chinese eyeliner tattoos over 10 years, Alexandrite picosecond laser does not provide better clearance than the Nd:YAG nanosecond laser.

The aim of the study was to assess whether the use of carbon dioxide insufflation has any impact on integrity of long saphenous vein comparing 2 types of endoscopic vein harvesting and traditional open vein harvesting. A total of 301 patients were prospectively randomized into 3 groups. Group 1 control arm of open vein harvesting (n = 101), group 2 closed tunnel (carbon dioxide) endoscopic vein harvesting (n = 100) and Group 3 open tunnel (carbon dioxide) endoscopic vein harvesting (open tunnel endoscopic vein harvesting) (n = 100). Each group was assessed to determine the systemic level of partial arterial carbon dioxide, end-tidal carbon dioxide, and pH. Three blood samples were obtained at baseline, 10 minutes after start of endoscopic vein harvesting, and 10 minutes after the vein was retrieved. Vein samples were taken immediately after vein harvesting without further surgical handling to measure the histological level of endothelial damage. A modified validated endothelial scoring system was used to compare the extent of endothelial stretching and detachment. The level of end-tidal carbon dioxide was maintained in the open tunnel endoscopic vein harvesting and open vein harvesting groups but increased significantly in the closed tunnel endoscopic vein harvesting group (P = 0.451, P = 0.385, and P < 0.001). Interestingly, partial arterial carbon dioxide also did not differ over time in the open tunnel endoscopic vein harvesting group (P = 0.241), whereas partial arterial carbon dioxide reduced significantly over time in the open vein harvesting group (P = 0.001). A profound increase in partial arterial carbon dioxide was observed in the closed tunnel endoscopic vein harvesting group (P < 0.001). Consistent with these patterns, only the closed tunnel endoscopic vein harvesting group demonstrated a sudden drop in pH over time (P < 0.001), whereas pH remained stable for both open tunnel endoscopic vein harvesting and open vein harvesting groups (P = 0.105 and P

Ultrasound-Guided Fine-Needle Aspiration of Non-palpable and Suspicious Axillary Lymph Nodes with Subsequent Removal after Tattooing: False-Negative Results and Concordance with Sentinel Lymph Nodes.

Ultrasonography-guided fine-needle aspiration (US-guided FNA) for axillary lymph nodes (ALNs) is currently used with various techniques for the initial staging of breast cancer and tagging of ALNs. With the implementation of the tattooing of biopsied ALNs, the rate of false-negative results of US-guided FNA for non-palpable and suspicious ALNs and concordance with sentinel lymph nodes were determined by node-to node analyses. A total of 61 patients with breast cancer had negative results for metastasis on US-guided FNA of their non-palpable and suspicious ALNs. The biopsied ALNs were tattooed with an injection of 1-3 mL Charcotrace (Phebra, Lane Cove West, Australia) ink and removed during sentinel lymph node biopsy or axillary dissection. We determined the rate of false-negative results and concordance with the sentinel lymph nodes by a retrospective review of surgical and pathologic findings. The association of false-negative results with clinical and imaging factors was evaluated using logistic regression. Of the 61 ALNs with negative results for US-guided FNA, 13 (21%) had metastases on final pathology. In 56 of 61 ALNs (92%), tattooed ALNs corresponded to the sentinel lymph nodes. Among the 5 patients (8%) without correspondence, 1 patient (2%) had 2 metastatic ALNs of 1 tattooed node and 1 sentinel lymph node. In multivariate analysis, atypical cells on FNA results (odds ratio = 20.7, p = 0.040) was independently associated with false-negative FNA results. False-negative ALNs after US-guided FNA occur at a rate of 21% and most of the tattooed ALNs showed concordance with sentinel lymph nodes.

We investigated the patient characteristic factors that correlate with identification of i.v. cannulation sites with normal eyesight. We evaluated a new infrared vein finding (VF) technology device in identifying i.v. cannulation sites. Each subject underwent two observations: one using the conventional method (CM) of normal, unassisted eyesight and the other with the infrared VF device, VueTek's Veinsite™ (VF). A power analysis for moderate effect size (β=0.95) required 54 samples for within-subject differences. Patient characteristic profiles were obtained from 384 subjects (768 observations). Our sample population exhibited an overall average of 5.8 [95% confidence interval (CI) 5.4-6.2] veins using CM. As a whole, CM vein visualization were less effective among obese [4.5 (95% CI 3.8-5.3)], African-American [4.6 (95% CI 3.6-5.5 veins)], and Asian [5.1 (95% CI 4.1-6.0)] subjects. Next, the VF technology identified an average of 9.1 (95% CI 8.6-9.5) possible cannulation sites compared with CM [average of 5.8 (95% CI 5.4-6.2)]. Seventy-six obese subjects had an average of 4.5 (95% CI 3.8-5.3) and 8.2 (95% CI 7.4-9.1) veins viewable by CM and VF, respectively. In dark skin subjects, 9.1 (95% CI 8.3-9.9) veins were visible by VF compared with 5.4 (95% CI 4.8-6.0) with CM. African-American or Asian ethnicity, and obesity were associated with decreased vein visibility. The visibility of veins eligible for cannulation increased for all subgroups using a new infrared device.

Leaf venation is diverse across plant species and has practical applications from paleobotany to modern agriculture. However, the impact of vein traits on plant performance has not yet been tested in a model system such as Arabidopsis thaliana. Previous studies analysed cotyledons of A. thaliana vein mutants and identified visible differences in their vein systems from the wild type (WT). We measured leaf hydraulic conductance (Kleaf ), vein traits, and xylem and mesophyll anatomy for A. thaliana WT (Col-0) and four vein mutants (dot3-111 and dot3-134, and cvp1-3 and cvp2-1). Mutant true leaves did not possess the qualitative venation anomalies previously shown in the cotyledons, but varied quantitatively in vein traits and leaf anatomy across genotypes. The WT had significantly higher mean Kleaf . Across all genotypes, there was a strong correlation of Kleaf with traits related to hydraulic conductance across the bundle sheath, as influenced by the number and radial diameter of bundle sheath cells and vein length per area. These findings support the hypothesis that vein traits influence Kleaf , indicating the usefulness of this mutant system for testing theory that was primarily established comparatively across species, and supports a strong role for the bundle sheath in influencing Kleaf . © 2015 John Wiley & Sons Ltd.

Corrosion cast study of the canine hepatic veins.

Uršič, M; Vrecl, M; Fazarinc, G

2014-11-01

This study presents a detailed description of the distribution, diameters and drainage patterns of hepatic veins on the basis of the corrosion cast analysis in 18 dogs. We classified the hepatic veins in three main groups: the right hepatic veins of the caudate process and right lateral liver lobe, the middle hepatic veins of the right medial and quadrate lobes and the left hepatic veins of both left liver lobes and the papillary process. The corrosion cast study showed that the number of the veins in the Nomina Anatomica Veterinaria and most anatomical textbooks is underestimated. The number of various-sized hepatic veins of the right liver division ranged from 3 to 5 and included 1 to 4 veins from the caudate process and 2 to 4 veins from the right lateral liver lobe. Generally, in all corrosion casts, one middle-sized vein from the right part of the right medial lobe, which emptied separately in the caudal vena cava, was established. The other vein was a large-sized vein from the remainder of the central division, which frequently joined the common left hepatic vein from the left liver lobes. The common left hepatic vein was the largest of all the aforementioned hepatic veins.

An 8-month old girl was presented with superior caval vein syndrome early after cardiac surgery. Angiography showed severe stenosis of the superior caval vein with 50 mmHg pressure gradient. Following balloon angioplasty, the pressure gradient was reduced to 7 mmHg with some residual stenosis of the superior caval vein. When the patient was reevaluated 5 months after the procedure, angiography revealed a normal diameter of the superior caval vein without a pressure gradient.

Histopathology and immune histochemistry of red tattoo reactions. Interface dermatitis is the lead pathology, with increase in T-lymphocytes and Langerhans cells suggesting an allergic pathomechanism.

The majority of tattoo reactions are affiliated to red pigmented areas and often suspected to be allergic in nature. A sizeable series of biopsies of such reactions has not previously been performed. The aim of this study was to type and grade epidermal and dermal changes in tattoo reactions to red/red nuances by microscopy and immunochemistry relevant for the assessment of a possible allergic pathomechanism. Skin biopsies were taken from red tattoo reactions, graded by conventional microscopy and stained for T and B-lymphocytes, Langerhans cells, macrophages and tumour necrosis factor (TNF)-α. The study included 19 biopsies from 19 patients. The culprit colours were red/pink (n = 15) and purple/bordeaux (n = 4). Interface dermatitis was clearly the lead pathology found in 78% of samples, overlapped with granulomatous (in 32%) and pseudolymphomatous reaction patterns (in 32%). Epidermal hyperkeratosis (in 89%) was common as was leakage of red pigment across the dermo-epidermal junction, with transepidermal elimination (in 28%). The dermal cellular infiltration was dominated by T-lymphocytes (in 100%), Langerhans cells (in 95%) and macrophages (in 100%). TNF-α was common. The predominant histological pattern of chronic tattoo reactions in red/red nuances is interface dermatitis. T-lymphocytes and Langerhans cells are increased suggesting an allergic pathomechanism. TNF-α may contribute to reactions. In many cases, overlapping reactive patterns were identified. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The umbilical and paraumbilical veins of man.

PubMed

Martin, B F; Tudor, R G

1980-03-01

During its transit through the umbilicus structural changes occur in the thick wall of the extra-abdominal segment of the umbilical vein whereby the components of the intra-abdominal segment acquire an essentially longitudinal direction and become arranged in fibro-elastic and fibro-muscular zones. The vein lumen becomes largely obliterated by asymmetrical proliferation of loose subendothelial conective tissue. The latter forms a new inner zone within which a small segment of the lumen persists in an eccentric position. This residual lumen transmits blood to the portal system from paraumbilical and systemic sources, and is retained in the upper part of the vein, even in old age. A similar process of lumen closure is observed in the ductus venosus. In early childhood the lower third of the vein undergoes breakdown, with fatty infiltration, resulting in its complete division into vascular fibro-elastic strands, and in old age some breakdown occurs in the outermost part of the wall of the upper two thirds. The paraumbilical veins are thick-walled and of similar structure to the umbilical vein. Together they constitute an accessory portal system which is confined between the layers of the falciform ligament and is in communication with the veins of the ventral abdominal wall. The constituents form an ascending series, namely, Burow's veins, the umbilical vein, and Sappey's inferior and superior veins. The main channel of Sappey's inferior veins may be the remnant of the right umbilical vein since it communicates with the right rectus sheath and often communicates directly with the portal system within the right lobe of the liver. The results are of significance in relation to clinical usage of the umbilical vein.

Idiopathic Bilateral External Jugular Vein Thrombosis.

PubMed

Hindi, Zakaria; Fadhel, Ehab

2015-08-20

Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow's triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present case shows that external jugular vein thrombosis can also be found in persons without malignancy.

Multimodal ultrasonographic assessment of leiomyosarcoma of the femoral vein in a patient misdiagnosed as having deep vein thrombosis

PubMed Central

2017-01-01

Abstract Rationale: Primary leiomyosarcoma (LMS) of the vein is a rare tumor that arises from the smooth muscle cells of the vessel wall and has an extremely poor prognosis. This tumor can occur in vessels such as the inferior vena cava, great saphenous vein, femoral vein, iliac vein, popliteal vein, and renal vein; the inferior vena cava is the most common site. LMS of the femoral vein can result in edema and pain in the lower extremity; therefore, it is not easy to be differentiated from deep vein thrombosis (DVT). Moreover, virtually no studies have described the ultrasonographic features of LMS of the vein in detail. Patient concerns: We present a case of a 55-year-old woman with LMS of the left femoral vein that was misdiagnosed as having deep vein thrombosis (DVT) on initial ultrasonographic examination. The patient began to experience edema and pain in her left leg seven months previously. She was diagnosed as having DVT on initial ultrasonographic examination, but the DVT treatment that she had received for 7 months failed to improve the status of her left lower limb. Diagnoses: She subsequently underwent re-examination by means of a multimodal ultrasonographic imaging approach (regular B-mode imaging, color Doppler imaging, pulsed-wave Doppler imaging, contrast-enhanced ultrasonography), which confirmed a diagnosis of LMS. Interventions: This patient was treated successfully with surgery. Outcomes: This case demonstrates that use of multiple ultrasonographic imaging techniques can be helpful to diagnose LMS accurately. Detection of vasculature in a dilated vein filled with a heterogeneous hypoechoic substance on ultrasonography is a sign of a tumor. Lessons: The pitfall of misdiagnosing this tumor as DVT is a useful reminder. PMID:29145269

Self-taught axillary vein access without venography for pacemaker implantation: prospective randomized comparison with the cephalic vein access.

Axillary vein access for pacemaker implantation is uncommon in many centres because of the lack of training in this technique. We assessed whether the introduction of the axillary vein technique was safe and efficient as compared with cephalic vein access, in a centre where no operators had any previous experience in axillary vein puncture. Patients undergoing pacemaker implantation were randomized to axillary or cephalic vein access. All three operators had no experience nor training in axillary vein puncture, and self-learned the technique by reading a published review. Axillary vein puncture was fluoroscopy-guided without contrast venography. Cephalic access was performed by dissection of delto-pectoral groove. Venous access success, venous access duration (from skin incision to guidewire or lead in superior vena cava), procedure duration, X-ray exposure, and peri-procedural (1 month) complications were recorded. results We randomized 74 consecutive patients to axillary (n = 37) or cephalic vein access (n = 37). Axillary vein was successfully accessed in 30/37 (81.1%) patients vs. 28/37 (75.7%) of cephalic veins (P = 0.57). Venous access time was shorter in axillary group than in cephalic group [5.7 (4.4-8.3) vs. 12.2 (10.5-14.8) min, P < 0.001], as well as procedure duration [34.8 (30.6-38.4) vs. 42.0 (39.1-46.6) min, P = 0.043]. X-ray exposure and peri-procedural overall complications were comparable in both groups. Axillary puncture was safe and faster than cephalic access even for the five first procedures performed by each operator. Self-taught axillary vein puncture for pacemaker implantation seems immediately safe and faster than cephalic vein access, when performed by electrophysiologists trained to pacemaker implantation but not to axillary vein puncture.

The anatomy of the cardiac veins in mice

Ciszek, Bogdan; Skubiszewska, Daria; Ratajska, Anna

2007-01-01

Although the cardiac coronary system in mice has been the studied in detail by many research laboratories, knowledge of the cardiac veins remains poor. This is because of the difficulty in marking the venous system with a technique that would allow visualization of these large vessels with thin walls. Here we present the visualization of the coronary venous system by perfusion of latex dye through the right caudal vein. Latex injected intravenously does not penetrate into the capillary system. Murine cardiac veins consist of several principal branches (with large diameters), the distal parts of which are located in the subepicardium. We have described the major branches of the left atrial veins, the vein of the left ventricle, the caudal veins, the vein of the right ventricle and the conal veins forming the conal venous circle or the prepulmonary conal venous arch running around the conus of the right ventricle. The venous system of the heart drains the blood to the coronary sinus (the left cranial caval vein) to the right atrium or to the right cranial caval vein. Systemic veins such as the left cranial caval, the right cranial caval and the caudal vein open to the right atrium. Knowledge of cardiac vein location may help to elucidate abnormal vein patterns in certain genetic malformations. PMID:17553104

Duplex investigations in children: Are clinical signs in children with venous disorders relevant?

Ultra sound colored duplex sonography is the preferred method in diagnosing chronic venous disease. Data in children on incidence, indications, and results are lacking. From the total of 9180 duplex investigations performed in our hospital from 2009 to 2012, data on indication and results of the investigation as well as patient characteristics were evaluated retrospectively for the proportion of pediatric patients. Duplex investigations were performed 49 times in 38 children (6-18 years), with an average of 1.3 times (1-6 times) per child. Forty percent showed abnormalities: 17 times deep venous thrombosis was suspected; deep venous thrombosis was objectified in 18%. In the 21 investigations performed for varicosis-related complaints, varicose veins or venous malformations were objectified in 57%. Edema was never a symptom of chronic venous disease. Duplex investigation is not often performed in children. In children with established deep venous thrombosis, a family history with deep venous thrombosis is common. In general, edema was not seen in children with varicose veins and, therefore, does not seem a reliable clinical sign at young age. © The Author(s) 2014.

The Origin of Fibrous Calcite Veins: Aragonite?

NASA Astrophysics Data System (ADS)

Elburg, M. A.; Bons, P. D.

2005-12-01

Truly fibrous calcite veins occur mainly in carbonaceous shales and are characterised by high length:width ratios of their fibres (>10). Previous studies on their Sr isotopic geochemistry (Elburg et al., 2002: Geol. Soc. London Spec. Publ. 200, 103-118; Hilgers and Sindern, 2005: Geofluids, in press) have shown that some of the material could be derived from the local wall rock. These studies also showed that the veins were always enriched in Sr compared to the calcite in the host rocks. Aragonite can contain significantly more Sr than calcite, while it also tends to have a fibrous crystal habit. It is therefore possible that the fibrous habit of these veins, which now consist of calcite, are a reflection of their initial aragonitic mineralogy, rather than of any special tectonic regime during their formation. This idea was investigated by analysing the major and trace element geochemistry of selected fibrous and non-fibrous calcite veins from Arkaroola (northern Flinders Ranges, Australia). The fibrous vein analysed for major elements contains less than 1% MgCO3, whereas calcite in the host rock, with which it is in Sr isotopic equilibrium, contains 18% MgCO3. Calcite can contain significant Mg, whereas the aragonitic structure cannot accomodate this ion, so this result is consistent with the idea of an original aragonitic mineralogy of the veins. The fibrous veins show an enrichment in the middle rare earth elements (REE) compared to the calcite in the host rock and blocky veins. In a Post-Archean Average Shale normalised diagram, Eu is more strongly enriched compared to its neighbouring elements in the fibrous veins, but not in the host calcite, blocky veins, or in the silicate fraction of the host rock, suggesting more reducing conditions during fibrous vein formation. This data cannot be used as direct evidence for the fibrous veins' aragonitic mineralogy. It does, however, show that significant differences exist between calcite in host rocks, blocky and

The deposits were discovered in 1861 and were worked sporadically until 1951, yielding more than 5,000 ounces of gold. The vein system and the principal veins within it strike a few degrees west of north, at an appreciable angle to foliation and fold axial planes in enclosing rocks of the Wissahickon Formation of late Precambrian (?) age. The veins cut granitic rocks of Devonian or pre-Devonian age and may be as young as Triassic. Further development of the deposits is unlikely under present economic conditions because of their generally low gold content and because much of the vein system lies on park property, but study of the Great Falls vein system may be useful in the search for similar deposits elsewhere in the Appalachian Piedmont.

Automatic detection of suspicious pain regions is very useful in the medical digital infrared thermal imaging research area. To detect those regions, we use the SOFES (Survival Of the Fitness kind of the Evolution Strategy) algorithm which is one of the multimodal function optimization methods. We apply this algorithm to famous diseases, such as a foot of the glycosuria, the degenerative arthritis and the varicose vein. The SOFES algorithm is available to detect some hot spots or warm lines as veins. And according to a hundred of trials, the algorithm is very fast to converge.

A 28-year-old man was hospitalized with nausea, vomiting, abdominal pain and low-grade fever. He had a 6-month history of paroxysmal nocturnal haemoglobinuria (PNH), and laboratory data showed anaemia and liver dysfunction. An abdominal ultrasonography showed ascites and portal vein thrombosis. After receiving antithrombotic treatment, the portal vein thrombosis did not extend. Portal vein thrombosis is very rare but should be considered when we encounter liver dysfunction associated with PNH as well as hepatic vein thrombosis. Ultrasonography is very useful in detecting portal vein thrombosis and facilitating early diagnosis. Warfarin is very effective in preventing exacerbation of portal vein thrombosis in PNH.

Portal vein thrombosis is an important cause of portal hypertension. PVT occurs in association with cirrhosis or as a result of malignant invasion by hepatocellular carcinoma or even in the absence of associated liver disease. With the current research into its genesis, majority now have an underlying prothrombotic state detectable. Endothelial activation and stagnant portal blood flow also contribute to formation of the thrombus. Acute non-cirrhotic PVT, chronic PVT (EHPVO), and portal vein thrombosis in cirrhosis are the three main variants of portal vein thrombosis with varying etiological factors and variability in presentation and management. Procoagulant state should be actively investigated. Anticoagulation is the mainstay of therapy for acute non-cirrhotic PVT, with supporting evidence for its use in cirrhotic population as well. Chronic PVT (EHPVO) on the other hand requires the management of portal hypertension as such and with role for anticoagulation in the setting of underlying prothrombotic state, however data is awaited in those with no underlying prothrombotic states. TIPS and liver transplant may be feasible even in the setting of PVT however proper selection of candidates and type of surgery is warranted. Thrombolysis and thrombectomy have some role. TARE is a new modality for management of HCC with portal vein invasion. PMID:25941431

The umbilical and paraumbilical veins of man.

PubMed Central

Martin, B F; Tudor, R G

During its transit through the umbilicus structural changes occur in the thick wall of the extra-abdominal segment of the umbilical vein whereby the components of the intra-abdominal segment acquire an essentially longitudinal direction and become arranged in fibro-elastic and fibro-muscular zones. The vein lumen becomes largely obliterated by asymmetrical proliferation of loose subendothelial conective tissue. The latter forms a new inner zone within which a small segment of the lumen persists in an eccentric position. This residual lumen transmits blood to the portal system from paraumbilical and systemic sources, and is retained in the upper part of the vein, even in old age. A similar process of lumen closure is observed in the ductus venosus. In early childhood the lower third of the vein undergoes breakdown, with fatty infiltration, resulting in its complete division into vascular fibro-elastic strands, and in old age some breakdown occurs in the outermost part of the wall of the upper two thirds. The paraumbilical veins are thick-walled and of similar structure to the umbilical vein. Together they constitute an accessory portal system which is confined between the layers of the falciform ligament and is in communication with the veins of the ventral abdominal wall. The constituents form an ascending series, namely, Burow's veins, the umbilical vein, and Sappey's inferior and superior veins. The main channel of Sappey's inferior veins may be the remnant of the right umbilical vein since it communicates with the right rectus sheath and often communicates directly with the portal system within the right lobe of the liver. The results are of significance in relation to clinical usage of the umbilical vein.

Black tattoo inks are composed of carbon nanoparticles, additives and water and may contain polycyclic aromatic hydrocarbons (PAHs). We aimed to clarify whether reactive oxygen species (ROS) induced by black inks in vitro is related to pigment chemistry, physico-chemical properties of the ink particles and the content of chemical additives and contaminants including PAHs. The study included nine brands of tattoo inks of six colours each (black, red, yellow, blue, green and white) and two additional black inks of different brands (n = 56). The ROS formation potential was determined by the dichlorofluorescein (DCFH) assay. A semiquantitative method was developed for screening extractable organic compounds in tattoo ink based on gas chromatography-mass spectrometry (GC-MS) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Two black inks produced high amounts of ROS. Peroxyl radicals accounted for up to 72% of the free radicals generated, whereas hydroxyl radicals and H₂O₂ accounted for <14% and 16%, respectively. The same two inks aggregated strongly in water in contrast to the other black inks. They did not exhibit any shared pattern in PAHs and other organic substances. Aggregation was exclusively shared by all ink colours belonging to the same two brands. Ten of 11 black inks had PAH concentrations exceeding the European Council's recommended level, and all 11 exceeded the recommended level for benzo(a)pyrene. It is a new finding that aggregation of tattoo pigment particles correlates with ROS production and brand, independently of chemical composition including PAHs. ROS is hypothesized to be implicated in minor clinical symptoms. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Based on 2014 United States dollars, the two-ultrasound surveillance paradigm is associated with health care charges of $31,109 per identified delayed venous thromboembolism event. Delayed duplex ultrasound assessment after ETA of the GSV comes with associated health care costs but does yield a significant number of patients with progression to EHIT. Better understanding of the timing, risk factors, and significance of EHIT is needed to cost-effectively care for patients after ETA for varicose veins. Copyright © 2016 Society for Vascular Surgery.

Vein segmentation is a vascular remodeling process mainly studied in experimental conditions and linked to hemodynamic factors, with clinical implications. The aim of this work is to assess the morphologic characteristics, associated findings, and mechanisms that participate in vein segmentation in humans. To this end, we examined 156 surgically obtained cases of hemorrhoidal disease. Segmentation occurred in 65 and was most prominent in 15, which were selected for serial sections, immunohistochemistry, and immunofluorescence procedures. The dilated veins showed differently sized spaces, separated by thin septa. Findings associated with vein segmentation were: (a) vascular channels formed from the vein intima endothelial cells (ECs) and located in the vein wall and/or intraluminal fibrin, (b) vascular loops formed by interconnected vascular channels (venous-venous connections), which encircled vein wall components or fibrin and formed folds/pillars/papillae (FPPs; the encircling ECs formed the FPP cover and the encircled components formed the core), and (c) FPP splitting, remodeling, alignment, and fusion, originating septa. Thrombosis was observed in some nonsegmented veins, while the segmented veins only occasionally contained thrombi. Dense microvasculature was also present in the interstitium and around veins. In conclusion, the findings suggest that hemorrhoidal vein segmentation is an adaptive process in which a piecemeal angiogenic mechanism participates, predominantly by intussusception, giving rise to intravascular FPPs, followed by linear rearrangement, remodeling and fusion of FPPs, and septa formation. Identification of other markers, as well as the molecular bases, hemodynamic relevance, and possible therapeutic implications of vein segmentation in dilated hemorrhoidal veins require further studies. © 2018 S.

Nephrotic Syndrome Associated with Renal Vein Thrombosis

1987-01-01

The coexistence of nephrotic syndrome and renal vein thrombosis has been of medical interest since Rayer’s description in 1840. Renal vein thrombosis has been underdiagnosed because of its variable clinical and radiological findings but it becomes a more frequently recognizable clinical entity since diagnosis can be easily established by modern angiographic techniques. Generally it has been believed that renal vein thrombosis may cause nephrotic syndrome. But recent articles strongly suggest that renal vein thrombosis is a complication of the nephrotic syndrome rather than a cause. We report three cases of nephrotic syndrome associated with renal vein thrombosis. PMID:3154812

Percutaneous Portal Vein Access and Transhepatic Tract Hemostasis

PubMed Central

Saad, Wael E. A.; Madoff, David C.

2012-01-01

Percutaneous portal vein interventions require minimally invasive access to the portal venous system. Common approaches to the portal vein include transjugular hepatic vein to portal vein access and direct transhepatic portal vein access. A major concern of the transhepatic route is the risk of postprocedural bleeding, which is increased when patients are anticoagulated or receiving pharmaceutical thrombolytic therapy. Thus percutaneous portal vein access and subsequent closure are important technical parts of percutaneous portal vein procedures. At present, various techniques have been used for either portal access or subsequent transhepatic tract closure and hemostasis. Regardless of the method used, meticulous technique is required to achieve the overall safety and effectiveness of portal venous procedures. This article reviews the various techniques of percutaneous transhepatic portal vein access and the various closure and hemostatic methods used to reduce the risk of postprocedural bleeding.

We analyzed the adverse events associated with an off-label use of arterial stents and CE-marked iliac vein stents for the treatment of iliac venous thromboembolism and investigated their relationships with the anatomical features of the iliac vein, to gain insights into the development of a better iliac vein stent. Reports of adverse events following the use of stents in the iliac vein were retrieved from the Manufacturer and User Facility Device Experience (MAUDE) database that contain suspected device-associated complications reported to the Food and Drug Administration. Data from 2006 to 2016 were investigated. The literature analysis was also conducted using PubMed, Cochrane Library, EMBASE, and Web of Science focusing on English articles published up to 4 October 2016. The analysis of 88 adverse events from the MAUDE database and 182 articles from the literature revealed that a higher number of adverse events had been reported following the use of arterial stents in the iliac vein compared to CE-marked iliac vein stents. While stent migration and shortening were reported only for the arterial stents, stent fracture and compression occurred regardless of the stent type, even though a vein does not pulsate. A study of the anatomical features of the iliac vein implies that bending, compression, and kink loads are applied to the iliac vein stents in vivo. For designing, developing, and pre-clinical testing of stents intended for use in the iliac vein, the above mechanical load environments induced by the anatomical features should be considered.

Facial surface electromyography (sEMG) is a powerful tool for objective evaluation of human facial expressions and was accordingly suggested in recent years for a wide range of psychological and neurological assessment applications. Owing to technical challenges, in particular the cumbersome gelled electrodes, the use of facial sEMG was so far limited. Using innovative facial temporary tattoos optimized specifically for facial applications, we demonstrate the use of sEMG as a platform for robust identification of facial muscle activation. In particular, differentiation between diverse facial muscles is demonstrated. We also demonstrate a wireless version of the system. The potential use of the presented technology for user-experience monitoring and objective psychological and neurological evaluations is discussed.

An effective hand vein feature extraction method.

2015-01-01

As a new authentication method developed years ago, vein recognition technology features the unique advantage of bioassay. This paper studies the specific procedure for the extraction of hand back vein characteristics. There are different positions used in the collecting process, so that a suitable intravenous regional orientation method is put forward, allowing the positioning area to be the same for all hand positions. In addition, to eliminate the pseudo vein area, the valley regional shape extraction operator can be improved and combined with multiple segmentation algorithms. The images should be segmented step by step, making the vein texture to appear clear and accurate. Lastly, the segmented images should be filtered, eroded, and refined. This process helps to filter the most of the pseudo vein information. Finally, a clear vein skeleton diagram is obtained, demonstrating the effectiveness of the algorithm. This paper presents a hand back vein region location method. This makes it possible to rotate and correct the image by working out the inclination degree of contour at the side of hand back.

To observe a case of congenital extrahepatic portosystemic shunt and discuss it from the embryological and clinical viewpoints. An 85-year-old female cadaver was employed for a dissection course at Aichi Medical University in 2009. There was no evidence of liver cirrhosis macroscopically or microscopically. A portosystemic shunt was observed that involved communication between the inferior mesenteric vein, inferior vena cava (IVC), and left ovarian vein by a single Y-shaped shunt vessel. To the best of our knowledge, this is the first reported case of the above-mentioned three veins being connected by a single Y-shaped shunt vessel. Considering the other venous diameters, the shunt appeared to flow into the splenic vein and IVC. It cannot be denied that this shunt may have led to hepatic encephalopathy, although the shunt effect may have been minimal. Embryological development of IVC appears to occur close to the plexus of anastomosing vitelline veins, forming the portal vein.

Effects of gravitational stress, hypokinesia and hypodynamia on the structure of the vascular bed of the spleen

1980-01-01

The effects of two extreme factors, hypokinesia and hypodynamia, on spleen vascular beds were studied on 180 male and female albino rats. Vessels were studied by roentgenography, microroentgenography, clearing of sections and histology. Gravity stress yielded construction of all links of arterial bed and of order 5-7 veins. Large intraorganic vein diameters changed significantly but erratically. Hypokinesia in early phases produced pronounced spleen size reduction. Veins and arteries constricted along entire length. Later hypokinetic stages showed arteries still constricted; veins began to dilate from week 4 of hypokinesia. Sinuosity, uneven contours and varicose dilations of walls in large arteries and veins occurred. Abrupt changes in parenchyma, e.g., atrophy of folliculi, narrowing of lumen of central arteries from thickening of muscular wall. After exposure to hypokinesia followed by gravitational stress, pronounced lesions such as deformation of vascular wall, including rupture, in all vessels of the spleen vascular bed.

Background: despite the proven effectiveness of preventive therapy for deep vein thrombosis, a significant proportion of patients at risk for thromboembolism do not receive prophylaxis during hospitalization. Our objective was to determine the adherence to thrombosis prophylaxis guidelines in a general hospital as a quality control strategy. Methods: a random audit of clinical charts was conducted at the Tijuana General Hospital, Baja California, Mexico, to determine the degree of adherence to deep vein thrombosis prophylaxis guidelines. The instrument used was the Caprini's checklist for thrombosis risk assessment in adult patients. Results: the sample included 300 patient charts; 182 (60.7 %) were surgical patients and 118 were medical patients. Forty six patients (15.3 %) received deep vein thrombosis pharmacologic prophylaxis; 27.1 % of medical patients received deep vein thrombosis prophylaxis versus 8.3 % of surgical patients (p < 0.0001). Conclusions: our results show that adherence to DVT prophylaxis at our hospital is extremely low. Only 15.3 % of our patients at risk received treatment, and even patients with very high risk received treatment in less than 25 % of the cases. We have implemented strategies to increase compliance with clinical guidelines.

Arterial aneurysms are more common than visceral venous aneurysms. Portal vein aneurysms being the most common type of visceral venous aneurysms. Here, we present an 18-year-old young woman with thalassaemia major, who presented with headache, palpitation, shortness of breath and a recent increase in blood transfusion rate. On clinical examination, she had hepatosplenomegaly. Ultrasonography revealed hepatosplenomegaly with fusiform dilatation of extrahepatic portal vein, which was confirmed to be portal vein aneurysm on contrast enhanced CT. Though portal vein aneurysms were previously thought to be rare, recently they are increasingly diagnosed with the use of cross-sectional imaging. Recognition of this finding can help to avoid potential confusion with other periportal cystic masses of different aetiologies, especially on sonography. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Day surgery is being more and more adopted by clinicians. Higher wavelength lasers give patients better experience than lower wavelength lasers, which makes it more suitable for day surgery. This study compares the short- and mid-term efficacy, postoperative morbidity, and patient satisfaction of "1470-nm endovenous laser ablation (EVLA) combining foam sclerotherapy in day surgery" with "810-nm EVLA with high ligation combining foam sclerotherapy in hospital surgery" on great saphenous vein (GSV) insufficiency postoperatively. A single-institution historical cohort study of 194 patients was performed in Shanghai Ninth People's Hospital, China. Ninety-seven patients received 1470-nm EVLA combining foam sclerotherapy in day surgery ("1470-nm group"), and 97 patients received 810-nm EVLA with high ligation combining foam sclerotherapy in hospital surgery recommended by guidelines ("810-nm group"). No significant difference was found between the 1470-nm group and the 810-nm group in terms of GSV occlusion rate (both 100%), complication rate, and recurrence rate (8.2 vs. 11.3%) during the period of 1-12 months after surgery. Serious complications in the 1470-nm group and 810-nm group were 0 and 1.0%. Minor complications in the 1470-nm group and 810-nm group were ecchymosis at 20.6 and 18.6%, edema at 69.1 and 63.9%, and paresthesia around ankle at 0 and 3.1%, respectively. Advantage of the 1470-nm group over the 810-nm group was statistically significant considering the patient perioperative comfort and economic cost. Treatment of 1470-nm EVLA combining foam sclerotherapy in day surgery has similar efficacy as the 810-nm EVLA with high ligation combining foam sclerotherapy in hospital surgery in GSV insufficiency and is more comfortable with less incision, hospitalization procedure, and medical costs. It may be a new option for patients who are afraid or unable to be hospitalized.

Multimodal ultrasonographic assessment of leiomyosarcoma of the femoral vein in a patient misdiagnosed as having deep vein thrombosis: A case report.

2017-11-01

Primary leiomyosarcoma (LMS) of the vein is a rare tumor that arises from the smooth muscle cells of the vessel wall and has an extremely poor prognosis. This tumor can occur in vessels such as the inferior vena cava, great saphenous vein, femoral vein, iliac vein, popliteal vein, and renal vein; the inferior vena cava is the most common site. LMS of the femoral vein can result in edema and pain in the lower extremity; therefore, it is not easy to be differentiated from deep vein thrombosis (DVT). Moreover, virtually no studies have described the ultrasonographic features of LMS of the vein in detail. We present a case of a 55-year-old woman with LMS of the left femoral vein that was misdiagnosed as having deep vein thrombosis (DVT) on initial ultrasonographic examination. The patient began to experience edema and pain in her left leg seven months previously. She was diagnosed as having DVT on initial ultrasonographic examination, but the DVT treatment that she had received for 7 months failed to improve the status of her left lower limb. She subsequently underwent re-examination by means of a multimodal ultrasonographic imaging approach (regular B-mode imaging, color Doppler imaging, pulsed-wave Doppler imaging, contrast-enhanced ultrasonography), which confirmed a diagnosis of LMS. This patient was treated successfully with surgery. This case demonstrates that use of multiple ultrasonographic imaging techniques can be helpful to diagnose LMS accurately. Detection of vasculature in a dilated vein filled with a heterogeneous hypoechoic substance on ultrasonography is a sign of a tumor. The pitfall of misdiagnosing this tumor as DVT is a useful reminder.

Finger vein extraction using gradient normalization and principal curvature

NASA Astrophysics Data System (ADS)

Choi, Joon Hwan; Song, Wonseok; Kim, Taejeong; Lee, Seung-Rae; Kim, Hee Chan

2009-02-01

Finger vein authentication is a personal identification technology using finger vein images acquired by infrared imaging. It is one of the newest technologies in biometrics. Its main advantage over other biometrics is the low risk of forgery or theft, due to the fact that finger veins are not normally visible to others. Extracting finger vein patterns from infrared images is the most difficult part in finger vein authentication. Uneven illumination, varying tissues and bones, and changes in the physical conditions and the blood flow make the thickness and brightness of the same vein different in each acquisition. Accordingly, extracting finger veins at their accurate positions regardless of their thickness and brightness is necessary for accurate personal identification. For this purpose, we propose a new finger vein extraction method which is composed of gradient normalization, principal curvature calculation, and binarization. As local brightness variation has little effect on the curvature and as gradient normalization makes the curvature fairly uniform at vein pixels, our method effectively extracts finger vein patterns regardless of the vein thickness or brightness. In our experiment, the proposed method showed notable improvement as compared with the existing methods.

Traumatic injury to the portal vein.

Traumatic injuries to the upper abdominal vasculature pose difficult management problems related to both exposure and associated injuries. Among those injuries that are more difficult to manage are those involving the portal vein. While occurring rarely, portal vein injuries require specific therapeutic considerations. Between January, 1968, and July, 1974, over 2000 patients were treated operatively for abdominal trauma at the Ben Taub General Hospital. Among these patients, 22 had injury to the portal vein. Seventeen portal vein injuries were secondary to gunshot wounds, 3 to stab wounds, and 2 to blunt trauma. Associated injuries to the inferior vena cava, pancreas, liver and bile ducts were common. Three patients had associated abdominal aortic injuries, two with acute aorto-caval fistulae. Nine patients died from from failure to control hemorrhage. Eleven were long-term survivors, including two who required pancreataico-duodenectomy as well as portal venorrhaphy. Late complications were rare. The operative approach to patients with traumatic injuries to multiple organs in the upper abdomen, including the portal vein, requires aggressive management and predetermined sequential methods of repair. In spite of innumerable associated injuries, portal vein injuries can be successfully managed in a significant number of patients using generally available surgical techniques and several adjunctive maneuvers.

A novel 3D reconstruction and fast imaging system for subcutaneous veins by augmented reality is presented. The study was performed to reduce the failure rate and time required in intravenous injection by providing augmented vein structures that back-project superimposed veins on the skin surface of the hand. Images of the subcutaneous vein are captured by two industrial cameras with extra reflective near-infrared lights. The veins are then segmented by a multiple-feature clustering method. Vein structures captured by the two cameras are matched and reconstructed based on the epipolar constraint and homographic property. The skin surface is reconstructed by active structured light with spatial encoding values and fusion displayed with the reconstructed vein. The vein and skin surface are both reconstructed in the 3D space. Results show that the structures can be precisely back-projected to the back of the hand for further augmented display and visualization. The overall system performance is evaluated in terms of vein segmentation, accuracy of vein matching, feature points distance error, duration times, accuracy of skin reconstruction, and augmented display. All experiments are validated with sets of real vein data. The imaging and augmented system produces good imaging and augmented reality results with high speed. PMID:27446690

Biometric identification is an emerging technology that can solve security problems in our networked society. A reliable and robust personal verification approach using dorsal hand vein patterns is proposed in this paper. The characteristic of the approach needs less computational and memory requirements and has a higher recognition accuracy. In our work, the near-infrared charge-coupled device (CCD) camera is adopted as an input device for capturing dorsal hand vein images, it has the advantages of the low-cost and noncontact imaging. In the proposed approach, two finger-peaks are automatically selected as the datum points to define the region of interest (ROI) in the dorsal hand vein images. The modified two-directional two-dimensional principal component analysis, which performs an alternate two-dimensional PCA (2DPCA) in the column direction of images in the 2DPCA subspace, is proposed to exploit the correlation of vein features inside the ROI between images. The major advantage of the proposed method is that it requires fewer coefficients for efficient dorsal hand vein image representation and recognition. The experimental results on our large dorsal hand vein database show that the presented schema achieves promising performance (false reject rate: 0.97% and false acceptance rate: 0.05%) and is feasible for dorsal hand vein recognition.

Finger vein verification is a promising biometric pattern for personal identification in terms of security and convenience. The recognition performance of this technology heavily relies on the quality of finger vein images and on the recognition algorithm. To achieve efficient recognition performance, a special finger vein imaging device is developed, and a finger vein recognition method based on sparse representation is proposed. The motivation for the proposed method is that finger vein images exhibit a sparse property. In the proposed system, the regions of interest (ROIs) in the finger vein images are segmented and enhanced. Sparse representation and sparsity preserving projection on ROIs are performed to obtain the features. Finally, the features are measured for recognition. An equal error rate of 0.017% was achieved based on the finger vein image database, which contains images that were captured by using the near-IR imaging device that was developed in this study. The experimental results demonstrate that the proposed method is faster and more robust than previous methods.

To compare internal jugular vein and subclavian vein access for central venous catheterization in terms of success rate and complications. A 1:1 randomized controlled trial. Baskent University Medical Center. Pediatric patients scheduled for cardiac surgery. Two hundred and eighty children undergoing central venous catheterization were randomly allocated to the internal jugular vein or subclavian vein group during a period of 18 months. The primary outcome was the first-attempt success rate of central venous catheterization through either approach. The secondary outcomes were the rates of infectious and mechanical complications. The central venous catheterization success rate at the first attempt was not significantly different between the subclavian vein (69%) and internal jugular vein (64%) groups (p = 0.448). However, the overall success rate was significantly higher through the subclavian vein (91%) than the internal jugular vein (82%) (p = 0.037). The overall frequency of mechanical complications was not significantly different between the internal jugular vein (25%) and subclavian vein (31%) (p = 0.456). However, the rate of arterial puncture was significantly higher with internal jugular vein (8% vs 2%; p = 0.03) and that of catheter malposition was significantly higher with subclavian vein (17% vs 1%; p < 0.001). The rates per 1,000 catheter days for both positive catheter-tip cultures (26.1% vs 3.6%; p < 0.001) and central-line bloodstream infection (6.9 vs 0; p < 0.001) were significantly higher with internal jugular vein. There were no significant differences between the groups in the length of ICU and hospital stays or in-hospital mortality rates (p > 0.05 for all). Central venous catheterization through the internal jugular vein and subclavian vein was not significantly different in terms of success at the first attempt. Although the types of mechanical complications were different, the overall rate was similar between internal jugular vein and

Tattooed persons examined with magnetic resonance imaging (MRI) can develop burning sensation suggested in the literature to be thermal burn from the procedure. MRI-induced thermal effect and magnetic behavior of known tattoo pigments were examined ex vivo. Magnetic resonance imaging effects on 3 commonly used commercial ink stock products marketed for cosmetic tattooing was studied. A main study tested 22 formulations based on 11 pigment raw materials, for example, one line of 11 called pastes and another called dispersions. Samples were spread in petri dishes and tested with a 0.97 T neodymium solid magnet to observe visual magnetic behavior. Before MRI, the surface temperature of the ink was measured using an infrared probe. Samples were placed in a clinical 3T scanner. Two scans were performed, that is, one in the isocenter and one 30 cm away from the center. After scanning, the surface temperature was measured again. Chemical analysis of samples was performed by mass spectroscopy. Mean temperature increase measured in the isocenter ranged between 0.14 and 0.26°C (P < .01) and in the off-center position from -0.16 to 0.21°C (P < .01). Such low increase of temperature is clinically irrelevant. Chemical analysis showed high concentrations of iron, but also nickel and chrome were found as contaminants. High concentration of iron was not associated with any increase of temperature or any physical draw or move of ink. The study could not confirm any clinically relevant temperature increase of tattoo pigments after MRI. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Epithelial biologists studying human skin diseases such as cancer formation and psoriasis commonly utilize mouse models to characterize the interplay among cells and intracellular signal transduction pathways that result in programmed changes in gene expression and cellular behaviors. The information obtained from animal models is useful only when phenotypic presentations of disease recapitulate those observed in humans. Excision of tissues followed by histochemical analysis is currently the primary means of establishing the morphological presentation. Non invasive imaging of animal models provides an alternate means to characterize tissue morphology associated with the disease of interest in vivo. While useful, the ability to perform in vivo imaging at different time points in the same tissue location has been a challenge. This information is key to understanding site specific changes as the imaged tissue can now be extracted and analyzed for mRNA expression. We present a method employing a micro-tattoo to guide optical coherence tomography (OCT) imaging of ultraviolet induced inflammation over time in the same tissue locations.

This report describes the successful use of portal venous stent placement for a patient with recurrent melena secondary to jejunal varices that developed after subtotal stomach preserved pancreatoduodenectomy (SSPPD). A 67-year-old man was admitted to our hospital with tarry stool and severe anemia at 2 years after SSPPD for carcinoma of the head of the pancreas. Abdominal computed tomography examination showed severe stenosis of the extrahepatic portal vein caused by local recurrence and showed an intensely enhanced jejunal wall at the choledochojejunostomy. Gastrointestinal bleeding scintigraphy also revealed active bleeding near the choledochojejunostomy. Based on these findings, jejunal varices resulting from portal vein stenosis were suspected as the cause of the melena. Portal vein stenting and balloon dilation was performed via the ileocecal vein after laparotomy. Coiling of the jejunal varices and sclerotherapy of the dilate postgastric vein with 5% ethanolamine oleate with iopamidol was performed. After portal stent placement, the patient was able to lead a normal life without gastrointestinal hemorrhage. However, he died 7 months later due to liver metastasis. PMID:24444277

A 67-year-old woman was admitted to our institution with pain, night cramping, and visible varicose veins on her left leg. Doppler ultrasonography revealed continuous reflux in the great saphenous vein when the patient did the Valsalva maneuver. Endovenous laser therapy was applied to the great saphenous vein. Doppler ultrasonography 7 days later showed recanalization of, and arterialized flow in, the great saphenous vein. There also were small arterial vessels adjunct to the recanalized side. A left femoral angiography via a right femoral approach showed multiple small arteriovenous fistulas between superficial femoral artery muscle branches and the great saphenous vein. Amore » second endovenous laser treatment was done at 80 J/cm, but the recanalization persisted. We offered to treat this endovascularly, but the patient preferred a surgical option. To the best of our knowledge, this is the first report of the demonstration of such a complication with endovenous laser therapy.« less

Injection of Light Material into an Older Dark Vein

NASA Image and Video Library

2015-11-11

Light material emplaced within darker vein material is seen in this view of a mineral vein at the "Garden City" site on lower Mount Sharp, Mars. The Mars Hand Lens Imager (MAHLI) on the arm of NASA's Curiosity Mars Rover took the image on April 4, 2015, during the 946th Martian day, or sol, of Curiosity's work on Mars. The area shown is roughly 0.4 inch (1 centimeter) wide. Differences in textures of light-toned veins in the Garden City complex of crisscrossing mineral veins are clues that these veins may result from distinct fluid events. This example shows where injection of light material into a prior dark vein suggests high fluid pressure. Differences in textures of light-toned veins in the Garden City complex of crisscrossing mineral veins are clues that these veins may result from distinct fluid events. This vein's texture shows indications of crystal growth, suggesting that crystallization may have exerted a force for opening the fracture filled by the vein. Different examples are at PIA19925 and PIA19927. Mineral veins often form where fluids move through fractured rocks, depositing minerals in the fractures and affecting chemistry of the surrounding rock. At Garden City, the veins have been more resistant to erosion than the surrounding host rock. The fluid movement through fractures at Garden City occurred later than wet environmental conditions in which the host rock formed, before it hardened and cracked. Malin Space Science Systems, San Diego, built and operates MAHLI.
