Abstract
BACKGROUND Indocyanine green (ICG) is a fluorescent dye with increasing use for adult sentinel lymph node biopsy (SLNB). The utility of ICG in pediatric oncology remains understudied. We aim to describe our experience using ICG for SLNB in pediatrics versus standard blue dye. METHODS A retrospective review of pediatric patients with melanoma or sarcoma who underwent SLNB with technetium plus ICG or blue dye from 2014 to 2023 at a large academic children's hospital was conducted. RESULTS Twenty-four patients were included; 58.3% were male with median age 13 years (range 4-21 years). The majority had a melanocytic tumor (91.7%) and 8.3% had sarcoma. All patients received technetium with concomitant blue dye (62.5%) or ICG (37.5%). ICG more reliably identified radioactive SLNs, compared to blue dye (mean 100% vs 78.3 ± 8.3%, p = 0.03). There was no significant difference in median operative time (ICG 82 min [68-203] vs blue dye 93 min [78-105], p = 0.84). Seven patients had positive SLNs (29.2%), with recurrence in 2 patients (8.3%) and 1 death (4.2%). There were no adverse events. CONCLUSION ICG-directed SLNB in children is a safe and effective alternative to blue dye. Use of ICG did not add to operative time, and more often identified sentinel nodes versus blue dye.

Abstract
Methylene blue (MB) has been shown to reduce mortality and morbidity in vasoplegic patients after cardiac surgery. Though MB is considered to be safe, extravasation of MB leading to cutaneous toxicity has been reported. In this study, we sought to characterize MB-induced cutaneous toxicity and investigate the underlying mechanisms. To induce MB-induced cutaneous toxicity, we injected 64 adult male Sprague-Dawley rates with 200 µL saline (vehicle) or 1%, 0.1%, or 0.01% MB in the plantar hind paws. Paw swelling, skin histologic changes, and heat and mechanical hyperalgesia were measured. Injection of 1%, but not 0.1% or 0.01% MB, produced significant paw swelling compared to saline. Injection of 1% MB produced heat hyperalgesia but not mechanical hyperalgesia. Pain behaviors were unchanged following injections of 0.1% or 0.01% MB. Global transcriptomic analysis by RNAseq identified 117 differentially expressed genes (111 upregulated, 6 downregulated). Ingenuity Pathway Analysis showed an increased quantity of leukocytes, increased lipids, and decreased apoptosis of myeloid cells and phagocytes with activation of IL-1β and Fos as the two major regulatory hubs. qPCR showed a 16-fold increase in IL-6 mRNA. Thus, using a novel rat model of MB-induced cutaneous toxicity, we show that infiltration of 1% MB into cutaneous tissue causes a dose-dependent pro-inflammatory response, highlighting potential roles of IL-6, IL-1β, and Fos. Thus, anesthesiologists should administer dilute MB intravenously through peripheral venous catheters. Higher concentrations of MB (1%) should be administered through a central venous catheter to minimize the risk of cutaneous toxicity.

Management of noncytotoxic extravasation injuries: A focused update on medications, treatment strategies, and peripheral administration of vasopressors and hypertonic saline. Pharmacotherapy 2023; 43:321-337. [PMID: 36938775 DOI: 10.1002/phar.2794] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 02/03/2023] [Accepted: 02/05/2023] [Indexed: 03/21/2023]
Abstract
Extravasation is the leakage of intravenous solutions into surrounding tissues, which can be influenced by drug properties, infusion techniques, and patient-related risk factors. Although peripheral administration of vesicants may increase the risk of extravasation injuries, the time and resources required for central venous catheter placement may delay administration of time-sensitive therapies. Recent literature gathered from the growing use of peripheral vasopressors and hypertonic sodium suggests low risk of harm for initiating these emergent therapies peripherally, which may prevent delays and improve patient outcomes. Physiochemical causes of tissue injury include vasoconstriction, pH-mediated, osmolar-mediated, and cytotoxic mechanisms of extravasation injuries. Acidic agents, such as promethazine, amiodarone, and vancomycin, may cause edema, sloughing, and necrosis secondary to cellular desiccation. Alternatively, basic agents, such as phenytoin and acyclovir, may be more caustic due to deeper tissue penetration of the dissociated hydroxide ions. Osmotically active agents cause cellular damage as a result of osmotic shifts across cellular membranes in addition to agent-specific toxicities, such as calcium-induced vasoconstriction and calcifications or arginine-induced leakage of potassium causing apoptosis. A new category has been proposed to identify absorption-refractory mechanisms of injury in which agents such as propofol and lipids may persist in the extravasated space and cause necrosis or compartment syndrome. Pharmacological antidotes may be useful in select extravasations but requires prompt recognition and frequently complex administration strategies. Historically, intradermal phentolamine has been the preferred agent for vasopressor extravasations, but frequent supply shortages have led to the emergence of terbutaline, a β2 -agonist, as an acceptable alternative treatment option. For hyperosmolar and pH-related mechanisms of injuries, hyaluronidase is most commonly used to facilitate absorption and dispersion of injected agents. However, extravasation management is largely supportive and requires a protocolized multidisciplinary approach for early detection, treatment, and timely surgical referral when required to minimize adverse events.

[PMCID: PMC10264870 DOI: 10.1007/s44254-023-00018-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 03/02/2023] [Accepted: 04/11/2023] [Indexed: 11/13/2023]
Abstract
The list of drugs patients may be exposed to during the perioperative and postoperative periods is potentially extensive. It includes induction agents, neuromuscular blocking drugs (NMBDs), opioids, antibiotics, sugammadex, colloids, local anesthetics, polypeptides, antifibrinolytic agents, heparin and related anticoagulants, blue dyes, chlorhexidine, and a range of other agents depending on several factors related to individual patients’ clinical condition and progress in the postoperative recovery period. To avoid poor or ultrarapid metabolizers to a particular drug (for example tramadol and codeine) or possible adverse drug reactions (ADRs), some drugs may need to be avoided during or after surgery. This will be the case for patients with a history of anaphylaxis or other adverse events/intolerances to a known drug. Other drugs may be ceased for a period before surgery, e.g., anticoagulants that increase the chance of bleeding; diuretics for patients with acute renal failure; antihypertensives relative to kidney injury after major vascular surgery; and serotonergic drugs that together with some opioids may rarely induce serotonin toxicity. Studies of germline variations shown by genotyping and phenotyping to identify a predisposition of genetic factors to ADRs offer an increasingly important approach to individualize drug therapy. Studies of associations of human leukocyte antigen (HLA) genes with some serious delayed immune-mediated reactions are ongoing and variations of drug-metabolizing cytochrome CYP450 enzymes, P-glycoprotein, and catechol-O -methyltransferase show promise for the assessment of ADRs and non-responses to drugs, particularly opioids and other analgesics. Surveys of ADRs from an increasing number of institutions often cover small numbers of patients, are retrospective in nature, fail to clearly identify culprit drugs, and do not adequately distinguish immune-mediated from non-immune-mediated anaphylactoid reactions. From the many surveys undertaken, the large list of agents identified during and after anesthesia and surgery are examined for their ADR involvement. Drugs are classified into those most often involved, (NMBD and antibiotics); drugs that are becoming more frequently implicated, namely antibiotics (particularly teicoplanin), and blue dyes; those becoming less frequently involved; and drugs more rarely involved in perioperative, and postoperative adverse reactions but still important and necessary to keep in mind for the occasional potential sensitive patient. Clinicians should be aware of the similarities between drug-induced true allergic type I IgE/FcεRI- and pseudoallergic MRGPRX2-mediated ADRs, the clinical features of each, and their distinguishing characteristics. Procedures for identifying MRGPRX2 agonists and diagnosing and distinguishing pseudoallergic from allergic reaction mechanisms are discussed.

J Pediatr Urol 2022; 19:217.e1-217.e6.

Abstract
OBJECTIVE Injection of methylene blue to testis has been shown to have adverse effect in animal studies but it is still being used frequently as lymphatic mapping agent during lymphatic sparing varicocelectomy in adolescent varicoceles. We aim to report postoperative ultrasound changes after subaortic injection of methylene blue in human testes. STUDY DESIGN A retrospective observational study of consecutive patients under 18 years old undergoing laparoscopic varicocelectomy from August 2017 to August 2021 was performed. Demographics such as age, symptoms, pre-operative testicular volume was collected. Primary outcome was change on testicular ultrasound at 3, 6, 12 months after the operation. Secondary outcome was testicular volume difference between affected and unaffected testes, and growth rate of affected testis at 1 year after the operation. RESULTS Fifty-eight patients were included, with median age of 15 years old (IQR 11-18 years). Thirty-one patients had non-lymphatic sparing varicocelectomy (Group A) and 27 patients had lymphatic sparing varicocelectomy (Group B). There was no statistical difference between the mean testicular volume difference between the two groups, but hydrocele rate was significantly higher in Group A (16% vs 0%, p = 0.03). In group B, 6 patients (22.2%, p = 0.005) developed testicular change detectable by ultrasound. No statistical difference could be demonstrated for median testicular size difference (between affected and unaffected testes) at 1 year between group with and without ultrasound change (-23% vs 0%, p = 0.36). Median follow up time was 20.4 months (IQR 5-32 months). DISCUSSION Varicocele treatments improve testicular volume and increase total sperm concentration and lymphatic sparing surgery significantly decreased post-operative hydrocele rates [2]. Different agents have been used to delineate lymphatic vessels and one commonly used agent is methylene blue [10,15-16]. However it has been shown in other animal studies that intraparenchymal injection of methylene blue to rat testis result in degenerative changes [18]. Our study is the first to describe post-operative changes of human testes on imaging after lymphatic sparing varicocelectomy with subdartoic injection of methylene blue. Six patients (22.2%) demonstrated new onset testicular changes on post-operative ultrasound. Although no statistically significant testicular volume reduction was seen in the group with change on imaging, these observations may serve as a surrogate marker for testicular injury or reduced testicular function. It will be desirable for future studies if we can investigate it further with hormonal markers or semen analysis after puberty has been reached. CONCLUSION Lymphatic sparing procedure reduced post-operative hydrocele in adolescent varicocele, however long-lasting effect on testis is evident with subdartoic injection of methylene blue. This agent must be used with caution and long term follow up of these patients are needed.

Abstract
Simple Summary Currently the gold standard for sentinel node biopsy in breast cancer patients is radioactive nanocolloid and a blue dye. In the age of fluorescence guided surgery new fluorophores are used and methylene blue presents some fluorescent properties. This study is the first in a clinical series presenting the possible use of methylene blue as a fluorescent dye for the identification of sentinel nodes in breast cancer sentinel node biopsy. We presented a feasibility of this new method and also in additional experiments because of the quenching effect limitation, found possible dilution of methylene blue presenting improved fluorescence. Abstract Introduction: Fluorescence-based navigation for breast cancer sentinel node biopsy is a novel method that uses indocyanine green as a fluorophore. However, methylene blue (MB) also has some fluorescent properties. This study is the first in a clinical series presenting the possible use of MB as a fluorescent dye for the identification of sentinel nodes in breast sentinel node biopsy. Material and methods: Forty-nine patients with breast cancer who underwent sentinel node biopsy procedures were enrolled in the study. All patients underwent standard simultaneous injection of nanocolloid and MB. We visualized and assessed the sentinel nodes and the lymphatic channels transcutaneously, with and without fluorescence, and calculated the signal-to-background ratio (SBR). We also analyzed the corresponding fluorescence intensity of various dilutions of MB. Results: In twenty-three patients (46.9%), the location of the sentinel node, or the end of the lymphatic path, was visible transcutaneously. The median SBR for transcutaneous sentinel node location was 1.69 (range 1.66–4.35). Lymphatic channels were visible under fluorescence in 14 patients (28.6%) prior to visualization by the naked eye, with an average SBR of 2.01 (range 1.14–5.6). The sentinel node was visible under fluorescence in 25 patients (51%). The median SBR for sentinel node visualization with MB fluorescence was 2.54 (range 1.34–6.86). Sentinel nodes were visualized faster under fluorescence during sentinel node preparation. Factors associated with the rate of visualization included diabetes (p = 0.001), neoadjuvant chemotherapy (p = 0.003), and multifocality (p = 0.004). The best fluorescence was obtained using 40 μM (0.0128 mg/mL) MB, but we also observed a clinically relevant dilution range between 20 μM (0.0064 mg/mL) and 100 μM (0.032 mg/mL). Conclusions: For the first time, we propose the clinical usage of MB as a fluorophore for fluorescence-guided sentinel node biopsy in breast cancer patients. The quenching effect of the dye may be the reason for its poor detection rate. Our analysis of different concentrations of MB suggests a need for a detailed clinical analysis to highlight the practical usefulness of the dye.

Abstract
Breast cancer surgery is associated with low rates of surgical morbidity. Postoperative complications related to breast surgery include seroma, infection, hematoma, mastectomy flap necrosis, wound dehiscence, persistent postsurgical pain, Mondor disease, fat necrosis, reduced tactile sensation after mastectomy, and venous thromboembolism. Postoperative complications related to axillary surgery include seroma, infection, lymphedema, nerve injury, and reduced shoulder/arm mobility. The overall rate of complication related to axilla surgery may be confounded by the type of breast surgery performed. The management of postoperative complications related to oncologic breast and axillary surgery independent of reconstruction is reviewed here.

Abstract
To prepare clinicians to treat extravasation of noncytotoxic vesicants with antidotes and thermal compresses, a literature review was performed to identify noncytotoxic vesicants and to create evidence and consensus-based recommendations. The stage of injury and vesicant's mechanism of tissue injury dictate treatment. For a vasopressor extravasation, warm compresses and administration of a vasodilator are recommended. For osmolarity, pH, absorption refractory, and cytotoxic concentration-dependent vesicants, warm compresses and administration of hyaluronidase are recommended. Compared with potentially catastrophic costs of undertreatment, the cost of overtreatment is minimal.

Abstract
Methylene blue (MB) is both a dye and a medicine known and used for a long time including as lymphatic tracer in melanoma and breast cancer for revealing sentinel lymph nodes. Proflavine (PRO) is an acriflavine dye, used as bacteriostatic disinfectant against many gram-positive bacteria that was also successfully applied to evaluate morphopathological changes in tissues. This study was performed on a group of twenty-eight Wistar rats and had as its main objective the in vivo evaluation of the use of MB and PRO as perforator tracers. The two dyes proved to be effective functional perforasome tracers with medium inflammatory infiltrate in the skin of the island perforator flap which heals perfectly at 14 days with complete absence of the inflammatory reaction. At the same injected amount, PRO seems to determine a greater inflammatory reaction compared with MB, but in smaller concentration, the inflammatory response is absent in the case of PRO. In conclusion, both substances tested within this in vivo study are good functional perforasome tracers, but PRO has the advantage of the absence of inflammatory reaction when using lower concentrations, while preserving unalerted its efficiency as tracer.

Abstract
Recently, most of the immediate breast reconstructions following mastectomy are being carried out with the use of silicone implants. In these patients, methylene blue is being used for the detection of sentinel lymph nodes. This experimental study was performed to determine the effect of methylene blue on capsular contracture around breast implants. Thirty-two Sprague Dawley rats were divided into 4 groups. Custom made silicone blocks were placed on the back of animals. In group 1, the incision was closed without performing any additional procedure. In group 2 (control), 0.1 mL of 0.9% normal saline was instilled into the pocket. Group 3 and 4 (study groups) received 0.1 and 0.2 mL of 1% methylene blue, respectively. On postoperative day 60, implants and capsular tissue were extracted. Capsule formation was evaluated both macroscopically and microscopically. The histological evaluation included capsule thickness, inflammation, neovascularization, and fibrosis gradients. Regarding capsule thickness, there were statistically significant differences between groups 1-3, 1-4, 2-3, and 2-4. Although there were more moderate and severe inflammation gradients in groups III and IV, there was no significant difference regarding inflammation severity between control and study groups. In respect of vascular proliferation, there was a statistically significant difference between control and study groups. Similarly, fibrosis gradients were higher in both groups 3 and 4. The study showed that the injection of methylene blue around silicone implants enhanced the formation of capsular contracture. In this case, the degree of contracture was independent of the dose given. Abbreviations: CC: capsular contracture; MM: methylene blue; SLNB: sentinel lymph node biopsy; NS: normal saline; H&E: hematoxylin and eosin; D: dorsal; V: ventral; L: lateral; n: frequency.

Sentinel Lymph Node Biopsy in Early Breast Cancer Using Methylene Blue Dye Alone: a Safe, Simple, and Cost-Effective Procedure in Resource-Constrained Settings. Indian J Surg Oncol 2021; 12:210-217. [PMID: 33814855 DOI: 10.1007/s13193-020-01273-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Accepted: 12/07/2020] [Indexed: 10/22/2022] Open
Abstract
Sentinel lymph node biopsy (SLNB) is done by different techniques in clinically node-negative patients with early breast cancer. In this study, we aim to estimate the identification rates, positivity rates, cost-effectiveness, and outcomes for patients who underwent sentinel node biopsy using methylene blue dye alone. This was a retrospective review of 172 patients with early breast cancer (cT1-3, N0) who underwent SLNB using methylene blue dye alone between January 2014 and December 2018 including their follow-up details until December 2019. The mean age was 51 ± 10.3 (range: 28 to 76) years. There were 63 (36.6%) patients with cT1 tumor, 108 (62.7%) with cT2, and only 1 patient with cT3 tumor. Breast conservation surgery was performed in 62 (36%) while the remaining 110 (64%) underwent simple mastectomy. Sentinel nodes were successfully identified in 165 (95.9%) with a positivity rate of 23.6%. There was no dye-related adverse reactions intra-operatively. The mean duration of follow-up was 26.68 ± 15.9 months (range: 1-60). Chronic arm pain was present in 7 (4%) while none of the patients had lymphedema or restriction of shoulder joint motion. There were no documented axillary nodal recurrences in this cohort. Eight (4.65%) patients were detected to have systemic metastasis. One patient died of brain metastasis from bilateral breast cancer. The mean disease-free survival was 57 months (95% CI: 55-59). Sentinel lymph node biopsy using methylene dye alone is a safe, simple, and cost-effective alternative to isosulfan blue or radio isotope technique in surgical centers with resource constraints.

Abstract
Metal-organic frameworks (MOFs) have emerged as promising candidates for a wide range of applications due to their high surface area and customizable structures, however, the minimal external hydrophilicity of MOFs has limited their biomedical implementations. Structuring of MOFs within polymer frameworks is an approach used to create hybrid materials that retain many of the MOF characteristics (e.g. high adsorption capacity) but expand the range of mechanical and surface properties as well as form factors accessible. Using this approach, hybridizing MOFs with hydrophilic hydrogels can give rise to materials with improved hydrophilicity and biocompatibility. Here, we describe the synthesis of the first Zr-based MOF-hydrogel hybrid material (composite 3) using a green chemistry approach, in which only water was used as the solvent and relatively low temperature (50 °C) was applied. Using methylene blue (MB) as a probe molecule, composite 3 exhibited greater adsorption capacity than the MOF or the hydrogel alone in aqueous solution at most tested pH values (all except pH 13). At an initial MB concentration of 0.0096 mg/mL (30.014uM) and neutral pH conditions, this new hybrid presented the highest loading of MB among similar materials (MB adsorbed = 4.361 ± 0.092 mg MB/g Zr, partition coefficient = 0.172 ± 0.004 mg/g/uM) and largely retained its adsorption capacity under varied conditions (pH 1-13 and 0.2-1.0M NaCl), rendering possible applications in drug delivery and the removal of tumor contrast agent/dye with minimal leakage due to its broad chemical stability.

Abstract
PURPOSE The usage of radioactive Technetium99m (Tc99m) colloid for the purpose of sentinel lymph node biopsy (SLNB) in early breast cancer is considered the gold standard in Germany. However, new tracers, such as near-infrared (NIR) imaging agents like indocyanine green (ICG) could offer an alternative in future, as they overcome drawbacks associated with radioactive Technetium99m (Tc99m) like limited availability, high costs and radioactivity exposure for both patients and surgeons. METHODS In this double-arm retrospective study, we sought to establish the usefulness of indocyanine green as an alternative or an addition to the conventional Technetium99m (Tc99m) in the identification of the SLN in early breast cancer. RESULTS Among the 161 patients who underwent primary SLNB, 34 patients had at least 1 SLN with metastasis. Among these patients with SLN metastasis, 33 had the SLN detected by ICG; while 31 had the SLN detected by Tc99m. The conventional Technetium99m radiotracer failed to detect 2 patients with metastasis in this Arm of the study. Among the 87 patients who underwent SLNB after NACT, 13 patients had at least 1 SLN with metastasis. Among these 13 patients with SLN metastasis, ICG and Tc99m had detected the SLN among 12 patients, while 1 patient had been detected by ICG alone. CONCLUSIONS Our results show that ICG is as effective as the radioisotope for SLNB even among patients who have undergone NACT. This trial is registered with the German Clinical Trial Register, ID: DRKS00013606.

Abstract
Background and objectives: Sentinel lymph node biopsy is important for metastasis surveillance in the management of a number of human cancers. Identification of sentinel lymph nodes may be facilitated by the use of several methods including methylene blue injection. However tissue necrosis is a known effect of methylene blue application. This study aimed to investigate the effects of methylene blue injection on skin flaps using a rodent model.Methods: Modified McFarlane flaps were prepared using Wistar Albino rats. Local injection of methylene blue was given to one group while saline was injected into the control group. A third group received systemic methylene blue via intraperitoneal injection. Observational and histological comparison was made between the groups to investigate the necrotic effects of methylene blue on skip flaps.Results: The control group's surviving flap areas were significantly larger than local methylene blue group's surviving flap area. However, there was no significant difference in skin flap survival area between the control group and the systemic methylene blue group. Furthermore, there is no significant difference between local and systemic methylene blue group's surviving flap areas.Conclusions: Local methylene blue injection increases skin necrosis and decreases rates of surviving flap areas in an experimental rat models.

Abstract
Purpose This study aimed to share our experience with SLNB in the Filipino population with early breast cancer. Patients and Methods A retrospective review was done on all patients with confirmed invasive breast carcinoma, tumor size of 5 cm or less (T1/T2), who preoperatively had no clinical signs of axillary metastasis and subsequently underwent SLNB with blue dye method from January 01, 2008 to December 31, 2017. Clinicopathologic profiles were recorded. Outcomes of patients who had SLNB only were assessed. Results One hundred twenty-nine patients matched the inclusion criteria with a mean age of 54.3 years. The majority (88.4%) had a total mastectomy. Invasive ductal carcinoma (65.1%) was the most common tumor. Estrogen and progesterone receptors were positive in 69% and 61.2% respectively while only 28.7% were HER2 positive. SLNB was successfully carried out in 126 (97.7%) patients with a range of 2-4 SLNs harvested. Thirty-four (26.4%) patients had completion ALND. With a median of 25 months follow-up, 75 out of 95 patients who underwent SLNB alone had follow-up data. Forty-six (61.3%) patients had seroma formation. One (1.3%) patient developed arm paresthesia, 2 (2.7%) local (chest wall) and 2 (2.7%) axillary recurrences after a negative SLNB. None of the patients developed lymphedema. Conclusion The blue dye method alone is acceptable and can be readily employed in institutions with limited resources. Even with the limited population, the morbidity and oncologic outcomes of patients who underwent SLNB alone were low and comparable to similar international published data. SLNB should be the preferred method for staging the axilla.

Abstract
Sentinel lymph node (SLN) mapping is a valuable and crucial diagnostic procedure in staging malignancies. We compared two non-invasive techniques, near-infrared (NIR) fluorescence imaging and contrast-enhanced ultrasound (CEUS), to identify the SLNs in three superficial anatomical regions in an animal model. Six healthy laboratory dogs were included in a proof-of-concept trial. A NIR fluorescent dye (Indocyanine Green) and microbubbles (Sonovue) were consecutively injected subdermally in the Inguinal, axillary and popliteal region to map the SLNs. Transcutaneous NIR fluorescence imaging identified SLNs in 17 out of a total of 18 occasions. CEUS identified SLNs in all regions (18/18). Whereas NIR fluorescence imaging performed better in the visualization of the afferent lymphatic tract, CEUS demonstrated different filling patterns of the SLNs, a feature potentially critical for the concept of SLN mapping in cancer patients. Both NIR fluorescence imaging and CEUS are safe, non-invasive, practical and accurate methods to perform real-time transcutaneous SLN mapping with potential in a clinical setting.

Abstract
Background Methylene blue dye is easy to obtain in developing countries and can be used in sentinel lymph node mapping for breast cancer. However, the accuracy of methylene blue alone for sentinel lymph node mapping in breast cancer has not been well defined. In this study, we collected data to assess the feasibility and accuracy of sentinel lymph node biopsy mapped with methylene blue alone in patients with breast cancer. Methods We searched the PubMed, EMBASE, and Cochrane Library databases from January 1, 1993, to March 31, 2018. Selected studies had to have a defined group of patients with breast cancer in which MBD alone was used as the mapping technique for SNB. Results 18 studies were included in this study. The combined identification rate was 91% [95% confidence interval (CI): 88%-94%, I2 = 68.3%], and the false negative rate was 13% (95% CI: 9%-18%, I2 = 36.7%). The pooled sensitivity, negative predictive value, and accuracy rate were 87% (95% CI: 82%-91%, I2 = 37.5%), 91% (95% CI: 87%-93%, I2 = 32.4%) and 94% (95% CI: 92%-96%, I2 = 29%), respectively. Conclusions This meta-analysis found that mapping sentinel lymph node locations with methylene blue dye alone results in an acceptable identification rate but an excessive false negative rate according to the American Society of Breast Surgeons’ recommendations. Caution is warranted when using methylene blue dye alone as the mapping method for sentinel lymph node biopsy.

Abstract
BACKGROUND To stage axillary lymph nodes in women with early-stage breast cancer, sentinel lymph node biopsy (SLNB), rather than axillary lymph node dissection (ALND), has been employed. Moreover, different tracer methods have various advantages and disadvantages. In recent years, carbon nanoparticle suspensions (CNSs) have been used as lymph node tracers during surgeries for thyroid cancer, gastric cancer, and colorectal cancer. The study retrospectively analyzed the feasibility and accuracy of CNS for sentinel lymph node (SLN) mapping in patients with early breast cancer. METHODS This single-center, retrospective study included breast cancer patients who underwent SLNB from January 1, 2016, to December 31, 2017, in the Department of Breast Cancer, Guangdong General Hospital. All patients received standard SLNB surgery using a CNS tracer. RESULTS A total of 332 cases were included in this study. The SLN identification rate was 99.1% (329/332), and the mean number of SLNs was 2.6 (range, 1-6). SLN metastasis was found in 62 (18.8%) cases, of which 90.3% were found to be macrometastases. The sensitivity of SLNB was 95.9% (47/49), with a specificity of 100% (42/42), a positive predictive value of 100% (47/47), a negative predictive value of 95.5% (42/44), and a false-negative rate of 4.1% (2/49). CONCLUSION The identification and predictive values of a CNS tracer for SLNB were satisfactory.

Abstract
Objective: This randomized study aimed to compare the clinical efficacy between the novel dual tracer composed of indocyanine green (ICG) and blue dye (BD) and the conventional dual tracer composed of radioisotope and BD for sentinel lymph node (SLN) mapping in patients with breast cancer. Methods: This study enrolled 471 clinically lymph node-negative patients with primary breast cancer. All patients underwent mastectomy, and those undergoing sentinel lymph node biopsy (SLNB) were randomized to receive blue dye plus radioisotope (RB group) or BD plus ICG (IB group). The detection performances on SLN identification rate, positive SLN counts, detection sensitivity, and false-negative rate were compared between the two groups. Results: In the IB group, 97% (194/200) of the patients who underwent the ICG and BD dual tracer injection showed fluorescent-positive lymphatic vessels within 2–5 min. The identification rate of SLNs was comparable between the IB group (99.0%, 198/200) and the RB group (99.6%, 270/271) (P = 0.79). No significant differences were observed in the identification rate of metastatic SLNs (22.5% vs. 22.9%, P > 0.05, RB group vs. IB group, the same below), positive SLN counts (3.72 ± 2.28 vs. 3.91 ± 2.13, P > 0.05), positive metastatic SLN counts (0.38 ± 0.84 vs. 0.34 ± 0.78, P > 0.05), SLNB detection sensitivity (94.4% vs. 92.5%, P > 0.05), or false-negative rate (5.6% vs. 7.5%, P > 0.05) between the two groups.
Conclusions: ICG can be used as a promising alternative tracer for radioisotope in SLN mapping, and when it is combined with BD in lymphangiography, it offers comparable detection sensitivity compared to the conventional lymphatic mapping strategies that are widely used in clinical practice.

Abstract
Management of the axilla in early breast cancer patients has significantly evolved in the last several decades. With the arrival of the sentinel lymph node biopsy, surgical practice for axillary staging in patients with early breast cancer has become gradually less invasive and formal axillary lymph node dissection has been confined to selected patients. Over the last two decades, evidence from randomized clinical trials have allowed for the de-escalation of axillary surgery in the management of early stage breast cancer. Advances in the staging and treatment of the axilla constitute a key component in determining initial surgical planning and therapeutic strategies in the treatment of early breast cancer. This chapter provides an updated review on the history, evolution, and current practices for axillary management in patients with early breast cancer, with particular attention to the surgical recommendations and controversial scenarios of the evolving management of the axilla.

Comparison of sentinel lymph node biopsy guided by indocyanine green, blue dye, and their combination in breast cancer patients: a prospective cohort study. World J Surg Oncol 2017; 15:196. [PMID: 29096643 PMCID: PMC5667473 DOI: 10.1186/s12957-017-1264-7] [Citation(s) in RCA: 63] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2017] [Accepted: 10/23/2017] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Recent studies show that near-infrared (NIR) fluorescence imaging using indocyanine green (ICG) has the potential to improve the performance of sentinel lymph node (SLN) mapping. The current cohort study was designed to assess the value of the combination of ICG and methylene blue (MB) dye in patients undergoing SLN biopsy. METHODS A prospective self-controlled trial was designed to detect the difference in the detection efficacies of ICG, MB, and combined ICG and MB (ICG + MB) navigation methods. Between 2010 and 2013, 198 consecutive early breast cancer patients eligible for sentinel lymph node biopsy were enrolled and 200 biopsy procedures were performed by injection of both ICG and MB. SLNs were searched and removed under the guidance of fluorescence and/or blue dye. The mapping characteristics, the detection rate of SLNs and positive SLNs, and the number of SLNs of ICG, MB, and ICG + MB were compared. Injection safety of ICG and MB was evaluated. RESULTS Fluorescence imaging of lymphatic flow, which is helpful to locate the incision site, could be seen in 184 of 200 procedures. The nodal detection rate of ICG, MB, and ICG + MB samples was 97, 89, and 99.5% (χ 2 = 26.2, p < 0.001), respectively, with the combination method yielding a superior identification result. The addition of ICG to the MB method resulted in the identification of more lymph nodes (median 3 versus 2) and more positive axillas (22.7% involved axillas were discovered by fluorescence only) than either method alone. No acute or chronic allergic reaction was observed in this study. However, 23 patients (23/82) who received breast-conserving therapy reported temporary skin staining, and 5 patients had permanent tattooing. Palpable subcutaneous nodules at the injection sites were reported in nine patients. There were no reports of skin necrosis. CONCLUSIONS The lymphatic navigation by ICG fluorescence detects SLNs at a high detection rate and improves the mapping performance when added to the MB method. The novel ICG + MB dual tracing modality, without involvement of radioactive isotopes, exhibits great potential as an alternative to traditional standard mapping methods.

Abstract
Surgical transection of sensory nerves in the treatment of intractable neuropathic pain is a commonly performed procedure. At times these cases can be particularly challenging when encountering obese patients, when targeting deeper nerves or those with a variable branching pattern, or in the case of repeat operations. In this case series, the authors describe their experience with ultrasound-guided surgical instrument placement during transection of a saphenous nerve in the region of prior vascular surgery in 1 patient and in the lateral femoral cutaneous nerve in 2 obese patients. The authors also describe this novel technique and provide pilot data that suggests ultrasound-assisted surgery may allow for complex cases to be completed in an expedited fashion through smaller incisions.

Abstract
Fresh water streams contaminated with synthetic dye-containing effluents pose a threat to aquatic and human life either by preventing aquatic photosynthesis or by entering into the food chain. Adsorptive removal of such dyes with potent biosorbents is an important technique to reduce bioaccumulation and biomagnifications of the dyes in human life. We report use of betel nut (BN) husk and banana peel (BP), two most abundant ligno-cellulosic wastes, as efficient adsorbents for the removal of the basic dye methylene blue (MB). The adsorption by BN and BP was consistently high over wide ranges of pH and temperature, suggesting their dye removal potential in diverse conditions. Physico-chemical studies, e.g. scanning electron microscopy and Fourier transform-infrared spectroscopy studies, revealed changes in surface topology and functional moieties of BN and BP post adsorption, implying dye interaction with the biomass surface. The dye adsorption in both cases followed pseudo-second-order kinetics. While adsorption of MB by BN was better fitted with the Temkin isotherm model, adsorption with BP followed both Langmuir and Freundlich isotherm models. Our studies concluded that both adsorbents efficiently remove MB from its aqueous solution with BP proved to be marginally superior to BN.

Abstract
Background Axillary lymph node dissection (ALND) has been the standard treatment of breast cancer axillary staging in Indonesia. The limited facilities of radioisotope tracer and isosulfan or patent blue dye (PBD) have been the major obstacles to perform sentinel node biopsy (SNB) in our country. We studied the application of 1% methylene blue dye (MBD) alone for SNB to overcome the problem. Methods This prospective study enrolled 108 patients with suspicious malignant lesions or breast cancer stages I–III. SNB was performed using 2–5 cc of 1% MBD and proceeded with ALND. The histopathology results of sentinel nodes (SNs) were compared with axillary lymph nodes (ALNs) for diagnostic value assessments. Results There were 96 patients with invasive carcinoma from July 2012 to September 2014 who were included in the final analysis. The median age was 50 (25–69) years, and the median pathological tumor size was 3 cm (1–10). Identification rate of SNs was 91.7%, and the median number of the identified SNs was 2 (1–8). Sentinel node metastasis was found in 53.4% cases and 89.4% of them were macrometastases. The negative predictive value (NPV) of SNs to predict axillary metastasis was 90% (95% CI, 81–99%). There were no anaphylactic reactions, but we found 2 cases with skin necrosis. Conclusions The application of 1% MBD as a single technique in breast cancer SNB has favorable identification rates and predictive values. It can be used for axillary staging, but nevertheless the technique should be applied with attention to the tumor size and grade to avoid false negative results.

Abstract
BACKGROUND Although morbidity is reduced when sentinel lymph node (SLN) biopsy is performed with dual isotopic and blue dye identification, the effectiveness of adding blue dye to radioisotope remains debated because side effects including anaphylactic reactions. PATIENTS AND METHODS Using data from a prospectively maintained database, 1884 lymph node-negative breast cancer patients who underwent partial mastectomy with SLN mapping by a dual-tracer using patent blue dye (PBD) and radioisotope were retrospectively studied between January 2000 and July 2013. Patients with tumors <3 cm and with >1 node detected by one of the two techniques (N = 1024) were included in this real-life cross-sectional study. RESULTS Among the 1024 patients, 274 had positive SLN detected by isotopic and/or PBD staining. Only 4 patients having no detectable radioactivity in the axilla had SLN identified only by PBD staining (blue-only) while 26 patients had SLN only identified by isotopic detection (hot-only) illustrating failure rates of 9.5% (26/274) and 1.5% (4/274), respectively. Among these four patients, two had negative lymphoscintigraphy. Therefore, the contribution of PBD to metastatic nodes identification was relevant for only 2/274 patients (0.8%). Three patients (0.3%) had an allergic reaction with PBD, and anaphylactic shock occurred in two cases (0.2%). CONCLUSIONS The added-value of PBD to reduce the false-negative rate of SLN mapping is only limited to the rare cases in which no radioactivity is detectable in the axilla (<1%). When a radioisotope mapping agent is available, the use of PBD should be avoided, because it can induce anaphylaxis.

Abstract
Breast cancer is the most common malignancy in women in well-developed countries. Despite a constant increase in its incidence, the percentage of patients diagnosed with the disease in the non-invasive stage is also rising. This allows more frequently for the use of breast-preserving surgical techniques, involving the breast and the regional lymphatic system. According to current guidelines of expert panels and research societies, the recommended method of identifying the sentinel lymph node is the use of an isotope marker with a dye (a combined isotope and dye method). Cooperation with a nuclear medicine unit is essential (performing a preoperative lymphoscintigraphic scan to identify the lymphatic drainage basin and sentinel lymph node). In the case of smaller centers treating breast cancer, it can be associated with a number of difficulties, including organizational ones, and also increasing general treatment costs. A possible solution to these problems is to use alternative techniques of visualizing the sentinel lymph node, which do not require a radiotracer. In this paper we discuss the currently available methods of mapping the lymphatic system of the axillary region in patients with early breast cancer. The review is limited to reporting on methods of proven (based on clinical research) high diagnostic value.

Abstract
One of surgical complications in cochlear implantation is the necrosis of the skin flap above the receiver-stimulator coil. We present a case of 55-year-old woman who underwent cochlear implantation and developed a bluish skin necrosis due to bone marking. The planned position for the receiver-stimulator was marked using methylene blue through skin to bone. She did not undergo skin flap thinning and underwent successful implantation with complete electrode insertion. Few weeks postoperatively, the patient developed bluish discoloration with progressive thick, blue eschar formation and skin flap necrosis. She subsequently underwent wound debridement and skin flap closure. Cochlear explantation was not necessary. Timely diagnosis and management about this complication is necessary to prevent further skin breakdown and subsequent device extrusion. This report identifies the marking using methylene blue as another possible source of skin flap necrosis in cochlear implantation, and surgeons should be aware of this potential complication.

Abstract
This article updates current knowledge on hypersensitivity reactions to diagnostic contrast media and dyes. After application of a single iodinated radiocontrast medium (RCM), gadolinium-based contrast medium, fluorescein, or a blue dye, a hypersensitivity reaction is not a common finding; however, because of the high and still increasing frequency of those procedures, patients who have experienced severe reactions are nevertheless frequently encountered in allergy departments. Evidence on allergologic testing and management is best for iodinated RCM, limited for blue dyes, and insufficient for fluorescein. Skin tests can be helpful in the diagnosis of patients with hypersensitivity reactions to these compounds.

Abstract
Sentinel lymph node (SLN) biopsy has become the gold standard for patients with melanoma and breast cancer but it’s clinical application in other solid tumor types such as cancers of the esophagus, stomach, colon and rectum, head and neck, penis, uterine cervix and endometrium has been somewhat limited. Commonly used mapping techniques utilizing the combination of radiocolloid and blue dye may result in reduced SLN detection and increased false negative rates when applied to cancers with more complex lymphatic drainage patterns. Novel localization techniques including near infrared fluorescence, high resolution imaging and molecular targeted agents have been developed to address the limitations of conventional SLN detection practices in many solid tumor types. This article reviews the indications, techniques and detection rates for SLN biopsy in several different solid tumor types as well as the promising novel techniques created to address the contemporary limitations of this procedure.

Abstract
Skin-sparing mastectomy with sentinel lymph node biopsy (SLNB) and synchronous breast reconstruction are widely used in breast cancer surgery nowadays. Difficulties in feeling confident in this technique and postoperative surgical complications are the major obstacles against the widespread usage of this technique. Compared with the other surgical techniques, the complications are hard to treat. Cutaneous necrosis because of methylene blue used for sentinel lymph node mapping in patients who underwent skin-sparing mastectomy and SLNB is already reported in the literature. We present here two cases with cutaneous necrosis because of isosulphane blue injection after skin-sparing mastectomy and SLNB as a rare complication of dye injection.

Methylene blue dye-induced skin necrosis in immediate breast reconstruction: evaluation and management. Arch Plast Surg 2014; 41:258-63.

Abstract
Background For early breast cancer patients, skin-sparing mastectomy or nipple-sparing mastectomy with sentinel lymph node biopsy has become the mainstream treatment for immediate breast reconstruction in possible cases. However, a few cases of skin necrosis caused by methylene blue dye (MBD) used for sentinel lymph node localization have been reported. Methods Immediate breast reconstruction using a silicone implant was performed on 35 breasts of 34 patients after mastectomy. For sentinel lymph node localization, 1% MBD (3 mL) was injected into the subareolar area. The operation site was inspected in the postoperative evaluation. Results Six cases of immediate breast reconstruction using implants were complicated by methylene blue dye. One case of local infection was improved by conservative treatment. In two cases, partial necrosis and wound dehiscence of the incision areas were observed; thus, debridement and closure were performed. Of the three cases of wide skin necrosis, two cases underwent removal of the dead tissue and implants, followed by primary closure. In the other case, the breast implant was salvaged using latissimus dorsi musculocutaneous flap reconstruction. Conclusions The complications were caused by MBD toxicity, which aggravated blood disturbance and skin tension after implant insertion. When planning immediate breast reconstruction using silicone implants, complications of MBD should be discussed in detail prior to surgery, and appropriate management in the event of complications is required.

Abstract
The purpose of this prospective pilot case study was to determine whether instillation of trypan blue dye into the uterine cavity before laparoscopic hysterectomy and morcellation aids in gross identification of endometrium. The most common commercially available trypan blue stain, VisionBlue was used in this study. Instillation was performed at the beginning of the procedure using an embryo transfer catheter. A sterile solution of trypan blue, 0.5 mL, was instilled transcervically into the uterine cavities in 12 patients before laparoscopic hysterectomy with uterine morcellation. The morcellated specimens were sent for routine gross pathologic and histologic examination. It was concluded that intrauterine instillation of trypan blue stained the endometrium, thus aiding the pathologist in identification of the endometrium in morcellated uterine specimens.

Abstract
OBJECTIVES The purpose of this study was to investigate the frequency and appearance of changes in the breast on sonography in patients after breast cancer surgery including sentinel lymph node localization using methylene blue dye. METHODS Three hundred thirty-seven consecutive patients who underwent breast-conserving surgery in 2006 underwent breast sonography during 2 years after surgery. Sentinel lymph node localization using methylene blue dye was selectively performed. We retrospectively analyzed the unexplained focal lesions not at the lumpectomy site on sonography and investigated whether these findings were associated with sentinel lymph node localization. RESULTS Unexplained focal lesions were identified in 36 (14.1%) of 256 patients who had undergone sentinel lymph node localization. The lesions were in the periareolar region (n = 26; outer in 16, upper in 6, inner in 2, and lower in 2) or the retroareolar region (n = 10). The lesion appeared with a fat necrosis-like pattern in the subcutaneous fat layer in 24 (66.7%) or as an irregular mass in the glandular layer in 12 (33.3%). The unexplained focal lesions were pathologically proven benign (n = 10) or were improved or stable during 2 years of imaging follow-up after surgery (n = 26). The unexplained focal lesions in 2 (2.5%) of 81 patients without sentinel lymph node localization were in the nonareolar region, and 1 of these was a recurrence. CONCLUSIONS After sentinel lymph node localization using methylene blue dye, breast sonography can show unexplained focal lesions in the periareolar and retroareolar regions. Although most of the changes suggest fat necrosis, an irregular parenchymal mass can develop and mimic a recurrence.

Abstract
AIMS Sentinel lymph node biopsy (SLNB) is an important method of staging early breast cancer because of the inherent benefits it confers on patients in terms of arm function and quality of life. Its success depends on a high level of accuracy in detecting the sentinel node. This is achieved by a dual mapping technique that employs a radio-labelled nanocolloid and a vital blue dye. The vital dyes however carry the risk of anaphylaxis, and as more surgeons employ SLNB in their daily practice, a proportionate rise in the number of anaphylactic reactions can be expected. A comprehensive review of risks and benefits associated with using vital blues dyes has not been published and therefore a retrospective review was undertaken of the different levels of anaphylaxis associated with vital dyes as well as their benefits in SLNB. METHODS An OVID MEDLINE search was performed of the English published literature using appropriate search terms to find published trial data and case series that focused on adverse reactions to vital blue dyes. RESULTS The risk of severe anaphylaxis (grade 3) can be as low as 0.06%, and up to 0.4% for patients undergoing SLNB when data is analysed from large trials. Furthermore, adverse reactions associated with blue dyes are reversible with appropriate management. CONCLUSIONS Surgeons should continue to use vital dyes to ensure that SLNB remains a highly sensitive procedure.

Abstract
BACKGROUND Sentinel lymph node biopsy (SNLB) is the standard of care in staging of melanoma and other skin cancers. Early studies used lymphazurin (LZ) for SLNB. A national shortage of LZ promoted methylene blue (MB) as an alternate stain. OBJECTIVE This study compares complication rates between LZ and MB in SLNB patients, and the reliability dyes in locating sentinel lymph nodes. METHODS Charts were reviewed for patients who underwent SLNB for skin cancers between September 2006 and November 2008 at Penn State Hershey Medical Center. The type and quantity of dye, the presence of blue stained sentinel nodes, and any complications were recorded. RESULTS Ninety-three patients underwent SLNB (46 LZ, 47 MB). The amount of dye used was similar (avg. 0.93 ml LZ, 1.24 ml MB). The complication rate of LZ was 8.7%, and MB was 25.5%. There was significantly more (P = 0.003) skin graft complications in the MB patients (6/12) versus LZ (0/15). CONCLUSIONS There is a higher rate of complications with MB, especially with skin grafting. The reported risk of anaphylaxis with LZ has not been reported in volumes <2 ml. The sentinel lymph node identification rate is historically similar between dyes, and in this study was noted to be higher with LZ.
