Continuous infusion of meropenem-vaborbactam for a KPC-3-producing Klebsiella pneumoniae bloodstream infection in a critically ill patient with augmented renal clearance.

PURPOSE: To demonstrate the feasibility of continuous infusion of meropenem-vaborbactam to optimize the treatment of carbapenem-resistant Enterobacterales. METHODS: Report of a case of a Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae bloodstream infection comfirmed by whole genome sequencing and therapeutic drug monitoring (TDM) of meropenem. RESULTS: A patient with augmented renal clearance (ARC) went into septic shock caused by an ST11 KPC-3-producing K. pneumoniae bloodstream infection that was successfully treated with a continuous infusion of meropenem-vaborbactam at a dosage of 1 g/1 g q4h as a 4-h infusion. TDM confirmed sustained concentrations of meropenem ranging from 8 to 16 mg/L throughout the dosing interval. CONCLUSION: Continuous infusion of meropenem-vaborbactam was feasible. It could be appropriate for optimizing the management of critically ill patients with ARC, as it resulted in antibiotic concentrations above the minimum inhibitory concentration for susceptible carbapenem-resistant Enterobacterales (up to 8 mg/L) throughout the dosing interval.

The Impact of Temporal Variation in ICG Administration on Axillary Node Identification During Reverse Mapping Procedures.

ICG with other tracers can be injected pre and/or per operatively to identify the axillary Lymph Nodes (LN) draining the breast cancer (the SLN nodes) and/or the ipsilateral arm (the ARM nodes). to evaluate the impact on this temporal variable-variation on the identification of these ARM LN. Material and methods: One hundred and nine women, who were scheduled to undergo, either lumpectomy with selective lymphadenectomy (SLN), or mammary surgery (either lumpectomy, or mastectomy) with complete axillary node dissection (CALND) for a histologically proven mammary tumor, had administered the day before the surgery one subcutaneous injection of ICG in the first interdigital space of the ipsilateral hand (pre-op subgroup (SLN=28 and CALND=15), or the same day as the surgery (per op subgroup (SLN=26 and CALND= 20). The fluorescent characteristics of the SLN and/or axillary LN were then analyzed and compared between the two subgroups. Results: Basic characteristics were not significantly different between the pre and per op subgroups. The percentage of patients found with fluorescent SLN (28%), the percentage of patients with fluorescent LN in CALND (74.5%), or the percentage of LN fluorescent in CALND (38.5%) did not differ significantly too. Conclusion: Injection of ICG in the first interdigital space of the hand of operated side performed one day before the surgery or the same day as the surgery has no significant influence in our study on detection of the arm nodes. The timing of ICG injection is an independent variable with no effect on the results; this allows the injection to be performed either the day before the surgery or the day of the surgery.

Ex vivo indocyanine green fluorescence imaging for the detection of lymph node involvement in advanced-stage ovarian cancer.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the role of indocyanine green (ICG) fluorescence imaging (FI) for the ex vivo detection of metastatic lymph nodes (LNs) in advanced stage ovarian cancer (AOC). METHODS: Paraffin-embedded LNs from patients included in a previous ICG-FI study (Protocol NCT01834469) were further assessed for fluorescence. Intravenous injection of ICG was delivered intraoperatively. Tumor-to-background ratios (TBRs) were calculated. RESULTS: A total of 675 LNs from 19 patients were analyzed. The mean LN number per patient was 29.3 (median: 24; range 2-77). Seventy-three LNs were malignant (10.8%), 602 were benign (89.2%). The mean TBR of all LNs was 1.5 (SD 0.8). With a cut-off TBR of 1.3, the sensitivity, specificity, positive predictive, and negative predictive values of ICG-FI for retroperitoneal LNs were 80%, 41%, 2.8%, and 99%, respectively. On univariate analysis, only the fluorescence ratio (TBR ≥ 1.3) was correlated with malignancy at pathology (P = 0.03). No predictive factors of pathological LN status were found on multivariate analysis. CONCLUSIONS: Ex vivo ICG-FI of retroperitoneal LNs in AOC had good sensitivity but poor specificity. However, its high negative predictive value could make it an appropriate complementary tool to focus pathological analysis on fluorescent LNs.

ICG-fluorescence imaging for detection of peritoneal metastases and residual tumoral scars in locally advanced ovarian cancer: A pilot study.

BACKGROUND AND OBJECTIVES: No intraoperative imaging techniques exist for detecting tumor nodules or tumor scar tissues in patients treated with upfront or interval cytoreductive surgery (CS) after neoadjuvant chemotherapy (NAC). The aims of this study were to evaluate the role of indocyanine green (ICG) fluorescence imaging (FI) for the detection of peritoneal metastases (PM) and evaluate whether it can be used to detect remnant tumor cells in scar tissue. METHODS: Patients with PM from ovarian cancer admitted for CS were included. ICG, at 0.25 mg per kg of patient weight, was injected intraoperatively after explorative laparotomy before CS. RESULTS: A total of 108 peritoneal lesions, including 25 scars, were imaged in 20 patients. Seventy-three were malignant (67.6%) and 35 benign (32.4%). The mean Tumor to Background Ratio (ex vivo) was 1.8 (SD 1.3) in malignant and 1.0 (SD 0.79) in benign nodules (P = 0.007). Of 25 post-NAC scars, the mean Tumor to Background Ratio (TBR) (in vivo) was 2.06 (SD 1.15) in malignant and 1.21 (SD 0.50) in benign nodules (P = 0.26). The positive predictive value of ICG-FI to detect tumor cells in scars was 57.1%. CONCLUSIONS: ICG-FI is accurate to demonstrate PM in ovarian cancer but unable to discriminate between benign and malignant post-NAC.

Use of lymphoscintigraphy to differentiate primary versus secondary lower extremity lymphedema after surgical lymphadenectomy: a retrospective analysis.

BACKGROUND: When managing patients with cancer, lymphedema of the lower limbs (LLL) is commonly reported as secondary to the surgical excision and/or irradiation of lymph nodes (LNs). In the framework of lymphoscintigraphic imaging performed to evaluate secondary LLL, some lympho-nodal presentations have been observed that could not be explained by the applied treatments, suggesting that these LLL might be primary. Therefore, all our lymphoscintigraphic examinations that were performed in patients for LLL after surgery for gynecological or urological cancer were retrospectively analyzed in order to evaluate the frequency in which these LLL might not be secondary (either completely or partially) but primary in origin. METHODS: Lymphoscintigraphies performed in 33 patients who underwent LN dissection (limited to the intra-abdominal LN) with or without radiotherapy for histologically confirmed ovarian cancer (n = 6), uterine cancer (n = 14 with cervical cancer and n = 7 with endometrial cancer), or prostate cancer (n = 6) were compared to lymphoscintigraphies obtained in primary LLL. RESULTS: In 12 (33% of the) patients (3 men plus 9 women, 4 with cervical cancer and 5 with endometrial cancer), scintigraphy of the lower limbs revealed lympho-nodal presentation that did not match with the expected consequences of the surgical and/or radiological treatments and were either suggestive or typical of primary lymphedema. CONCLUSIONS: This retrospective analysis of a limited but well-defined series of patients suggests that the appearance of LLL might not be related to cancer treatment(s) but that these LLL may represent the development of a primary lymphatic disease latent prior to the therapeutic interventions.

Fluorescence of Deep Infiltrating Endometriosis During Laparoscopic Surgery: A Preliminary Report on 6 Cases.

BACKGROUND: The standard treatment of rectovaginal deep infiltrating endometriosis nodules (RVDIEN) consists in their surgical removal. RVDIEN are anatomically neovascularized. Indocyanine green (ICG) reveals vascularized structures when becoming fluorescent after exposure to near-infrared (NIR) light. This study aims to evaluate if fluorescence-guided surgery can improve the laparoscopic resection of RVDIEN, thus avoiding a rectal perforation. MATERIALS AND METHODS: Patients with a symptomatic RVDIEN, scheduled for a laparoscopic rectal shaving, were enrolled in the study. Technically, the RVDIEN was targeted and removed with the help of the NIR imager device Image 1 Spies (Karl Storz GmBH & Co KG, Tuttlingen, Germany) or Visera Elite II (Olympus Europe SE & Co KG, Hamburg, Germany), after an intraoperative, intravenous injection of ICG (0.25 mg/kg). RESULTS: Six patients underwent a fluorescence-guided laparoscopic shaving procedure for the treatment of a nonobstructive RVDIEN. Fluorescence of the RVDIEN was observed in all the patients. In one patient, once the main lesion was removed, the posterior vaginal fornix still appeared fluorescent and was removed. No intraoperative rectal perforation occurred. The postoperative hospital stay was 2 days. No postoperative rectovaginal fistula occurred within a median follow-up of 16 months (range = 2-23 months). CONCLUSION: In this preliminary study, fluorescence-guided laparoscopy appeared to help in separating the RVDIEN from the healthy rectal tissue, without rectal perforation. Moreover, this technique was helpful in deciding if the resection needed to be enlarged to the posterior vaginal fornix.

Fluorescence Imaging After Indocyanine Green Injection for Detection of Peritoneal Metastases in Patients Undergoing Cytoreductive Surgery for Peritoneal Carcinomatosis From Colorectal Cancer: A Pilot Study.

OBJECTIVE: The aim of this study was to evaluate the role of fluorescence imaging (FI) using an intraoperative injection of free indocyanine green (ICG) in the detection of peritoneal metastases (PM) due to colorectal cancer (CRC). BACKGROUND: A large proportion of patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy will have local recurrence. This is, in part, related to the presence of small undetected nodules in the peritoneal cavity. Near-infrared FI-guided surgery has provided new opportunities for detection of nonvisible lesions during cancer surgery. METHODS: Patients with PM from CRC admitted for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were selected for participation in this study (NCT02032485). Free ICG, at 0.25 mg/kg of patient weight, was intravenous (IV)-injected intraoperatively. Tumor-to-background ratio was calculated for all suspect resected PM. RESULTS: Sixty-three of 78 peritoneal resected nodules in 14 patients were evaluated for fluorescence, among them, 53 were malignant (84%) and 10 benign (16%). Twenty-six were hypofluorescent, 16 moderately hyperfluorescent, and 21 hyperfluorescent. Amongst the 42 nodules of the 9 patients with nonmucinous adenocarcinoma, the mean tumor-to-background ratio was 1.92 (SD 0.67) in malignant and 1.02 (SD 0.06) in benign nodules (P = 0.0099). In 4 of 14 patients (29%), the surgery was modified by intraoperative ICG-FI, which detected additional PM not found using visualization and palpation. CONCLUSIONS: This pilot study demonstrates that non-mucinous PM of CRC can be visualized intraoperatively using ICG-FI. Furthermore, ICG-FI findings resulted in modification of the planned surgery in 29% of patients.

Ex vivo detection of tumoral lymph nodes of colorectal origin with fluorescence imaging after intraoperative intravenous injection of indocyanine green.

BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the potential role of indocyanine green (ICG) fluorescence imaging after intraoperative intravenous (IV) injection for the "ex vivo" detection of metastatic lymph nodes (mLNs) of colorectal cancer origin. METHODS: Fresh-fixed LNs in cassettes and/or paraffin-embedded LNs of patients included in a study that evaluated the role of ICG in the detection of peritoneal metastases of colorectal origin (Protocol NCT-01995591) were further explored with a dedicated near-infrared camera system for their fluorescence. An IV injection of ICG was delivered intraoperatively at 0.25 mg/kg. Signal to background ratios (SBRs) were calculated. RESULTS: LNs on operative specimens were evaluated for 12 patients (5 males, 7 females). A total of 182 LNs were analyzed. The mean LN number per patient was 15.2 (median: 15.5; range 3-22). SBRs of mLNs were significantly more fluorescent than benign LNs, 1.41 versus 1.04 arbitrary units (P < 0.0002). On univariate analysis, fluorescence was statistically correlated with LN surface area (>20 mm(2) ) (P < 0.0004). CONCLUSION: Ex vivo ICG fluorescence imaging after intraoperative IV injection represents a potential method for detecting invaded LN's of colorectal cancer origin on operative specimens. Further clinical studies are needed to better define optimal techniques. J. Surg. Oncol. 2016;114:348-353. © 2016 Wiley Periodicals, Inc.

Time trends in axilla management among early breast cancer patients: Persisting major variation in clinical practice across European centers.

Background We examined time trends in axilla management among patients with early breast cancer in European clinical settings. Material and methods EUROCANPlatform partners, including population-based and cancer center-specific registries, provided routinely available clinical cancer registry data for a comparative study of axillary management trends among patients with first non-metastatic breast cancer who were not selected for neoadjuvant therapy during the last decade. We used an additional short questionnaire to compare clinical care patterns in 2014. Results Patients treated in cancer centers were younger than population-based registry populations. Tumor size and lymph node status distributions varied little between settings or over time. In 2003, sentinel lymph node biopsy (SLNB) use varied between 26% and 81% for pT1 tumors, and between 2% and 68% for pT2 tumors. By 2010, SLNB use increased to 79-96% and 49-92% for pT1 and pT2 tumors, respectively. Axillary lymph node dissection (ALND) use for pT1 tumors decreased from between 75% and 27% in 2003 to 47% and 12% in 2010, and from between 90% and 55% to 79% and 19% for pT2 tumors, respectively. In 2014, important differences in axillary management existed for patients with micrometastases only, and for patients fulfilling the ACOSOG Z0011 criteria for omitting ALND. Conclusion This study demonstrates persisting differences in important aspects of axillary management throughout the recent decade. The results highlight the need for international comparative patterns of care studies in oncology, which may help to identify areas where further studies and consensus building may be necessary.

Tumour targeting and radiation dose of radioimmunotherapy with (90)Y-rituximab in CD20+ B-cell lymphoma as predicted by (89)Zr-rituximab immuno-PET: impact of preloading with unlabelled rituximab.

PURPOSE: To compare using immuno-PET/CT the distribution of (89)Zr-labelled rituximab without and with a preload of unlabelled rituximab to assess the impact of preloading with unlabelled rituximab on tumour targeting and radiation dose of subsequent radioimmunotherapy with (90)Y-labelled rituximab in CD20+ B-cell lymphoma. METHODS: Five patients with CD20+ B-cell lymphoma and progressive disease were prospectively enrolled. All patients underwent three study phases: initial dosimetric phase with baseline (89)Zr-rituximab PET/CT imaging without a cold preload, followed 3 weeks later by a second dosimetric phase with administration of a standard preload (250 mg/m(2)) of unlabelled rituximab followed by injection of (89)Zr-rituximab, and a therapeutic phase 1 week later with administration of unlabelled rituximab followed by (90)Y-rituximab. PET/CT imaging and tracer uptake by organs and lesions were assessed. RESULTS: With a cold rituximab preload, the calculated whole-body dose of (90)Y-rituximab was similar (mean 0.87 mSv/MBq, range 0.82-0.99 mSv/MBq) in all patients. Without a preload, an increase in whole-body dose of 59% and 87% was noted in two patients with preserved circulating CD20+ B cells. This increase in radiation dose was primarily due to a 12.4-fold to 15-fold higher dose to the spleen without a preload. No significant change in whole-body dose was noted in the three other patients with B-cell depletion. Without a preload, consistently higher tumour uptake was noticed in patients with B-cell depletion. CONCLUSION: Administration of the standard preload of unlabelled rituximab impairs radioconjugate tumour targeting in the majority of patients eligible for radioimmunotherapy, that is patients previously treated with rituximab-containing therapeutic regimens. This common practice may need to be reconsidered and further evaluated as the rationale for this high preload has its origin in the "prerituximab era".

Effect of radiation therapy on lymph node fluorescence in head and neck squamous cell carcinoma after intravenous injection of indocyanine green: a prospective evaluation.

BACKGROUND: Indocyanine green (ICG)-guided surgery has proven effective in the identification of neoplastic tissues. The effect of radiation therapy (RT) on lymph node fluorescence after intravenous injection of ICG has not been addressed yet. The objective of this study was to evaluate the influence of RT on node fluorescence during neck dissection in head and neck squamous cell carcinoma (HNSCC). RESULTS: Twenty-four patients with planned neck dissection for HNSCC were prospectively enrolled. Eleven were included without previous radiation therapy and 13 after RT. ICG was intravenously administered in the operating room. The resected specimen was analyzed by the pathology department to determine the status of each resected lymph node (invaded or not). The fluorescence of each resected node was measured in arbitrary units (AU) on paraffin blocs. The surface area (mm2) of all metastatic nodes and of the invaded component were measured. The values of these surface areas were correlated to fluorescence values. A total of 707 nodes were harvested, the mean fluorescence of irradiated nodes (n = 253) was 9.2 AU and of non-irradiated nodes (n = 454) was 9.6 AU (p = 0.63). Fifty nodes were invaded, with a mean fluorescence of 22 AU. The mean fluorescence values in the invaded irradiated nodes (n = 20) and the invaded non-irradiated nodes (n = 30) were 19 AU and 28 AU (p = 0.23), respectively. The surface area of metastatic nodes and of the invaded component were correlated to fluorescence values even after previous RT (p = 0.02). CONCLUSION: No differences were observed between the fluorescence of irradiated and non-irradiated lymph nodes, including invaded nodes. ICG-guided surgery can be performed after failed RT.

Who are the patients with early arthritis with worse than death scores on the EQ-5D? Results from the ESPOIR cohort.

OBJECTIVES: The EQ-5D is a five-dimension multi-attribute questionnaire widely used to calculate quality-adjusted life-year scores. We aimed to describe patients with early arthritis (EA) and EQ-5D < 0, a state worse than death, at baseline and over 2 years and determine aspects of EA associated with a negative score. METHODS: EQ-5D scores for 813 patients were longitudinally assessed over 24 months. Characteristics and health status of patients with EQ-5D < 0 were analysed. Multivariate logistic regression was used to determine aspects of EA associated with a negative score. RESULTS: At baseline, 90 (11%) patients had a negative EQ-5D score (median EQ-5D -0.052; range -0.530 to -0.011). Almost all patients had extreme pain/discomfort and at least moderate problems in anxiety/depression domain. These patients had lower educational level, greater disease activity, higher HAQ score (greater functional disability), greater pain and fatigue, lower Short Form 36 (SF-36) mental component scores and higher CRP levels than patients with EQ-5D ≥ 0 (all P < 0.001). In the logistic regression model, worse HAQ and SF-36 mental component scores were associated with EQ-5D < 0. Results were similar at 6, 12 and 24 months, with 25, 23 and 24 patients, respectively, in a state worse than death. CONCLUSION: Pain or discomfort, often severe, is a key domain of the EQ-5D for patients with EA in a health state worse than death, and poor HAQ and SF-36 mental component scores were always independently associated with a state worse than death. EA patients may have specific needs necessitating better management of pain and psychological state.

Power Doppler ultrasound, but not low-field magnetic resonance imaging, predicts relapse and radiographic disease progression in rheumatoid arthritis patients with low levels of disease activity.

OBJECTIVE: Subclinical inflammation and radiographic progression have been described in rheumatoid arthritis (RA) patients whose disease is in remission or is showing a low level of activity. The aim of this study was to compare the ability of ultrasonography and magnetic resonance imaging (MRI) to predict relapse and radiographic progression in these patients. METHODS: Patients with RA of short or intermediate duration that was either in remission or exhibiting low levels of activity according to the Disease Activity Score (DAS) were included in the study. Over a period of 1 year, patients underwent clinical and biologic assessments every 3 months and radiographic assessments at baseline and 12 months. Radiographs were graded according to the modified Sharp/van der Heijde score (SHS). At baseline, patients underwent ultrasonography and MRI, which were graded using binary and semiquantitative scoring systems. Relapse was defined as a DAS of ≥2.4, and radiographic progression was defined as an increase in the SHS of ≥1. We tested the association of values by multivariate logistic regression. RESULTS: A total of 85 RA patients with a mean disease duration of 35.3 months were studied. RA was in remission in 47 of these patients, and 38 had low levels of disease activity. At 1 year, 26 of the 85 patients (30.6%) showed disease relapse, and 9 of the 85 patients (10.6%) showed radiographic progression. The baseline PD synovitis count (i.e., the number of joints at baseline for which the power Doppler [PD] signal indicated synovitis) predicted relapse (adjusted odds ratio [OR] 6.3; 95% confidence interval [95% CI] 2.0-20.3), and the baseline PD synovitis grade predicted disease progression (adjusted OR 1.4 [95% CI 1.1-1.9]). MRI was not predictive of outcomes. CONCLUSION: For RA patients whose disease is in remission or who have low levels of disease activity, PD signals on ultrasonography could predict relapse or radiographic progression and identify those whose disease is adequately controlled, which is especially helpful when considering treatment tapering or interruption.

Indo-cyanine green administration to identify loss of lymph after axillary lymph node dissection.

Background: Near infrared fluorescence imaging with Indocyanine Green (ICG) is now used for the imaging of lymph nodes and lymphatic vessels. In this work, we investigated the impact of its pre-operative and peri-operative administration on our ability to detect axillary lymphatic loss after breast cancer surgery. Methods: One subcutaneous injection of ICG was administered in the ipsilateral hand of 109 women who were scheduled to have either a mastectomy with total axillary lymph node dissection (CALND) or a lumpectomy with selective lymphadenectomy (SLN) the day before (n = 53) or the same day of surgery (n = 56). The lymph leakages were assessed by means of the application of a compress in the operated armpit and by the presence or absence of fluorescence on it, as well as in the post-operative axillary drains. Results: The compress was fluorescent in 28% of SLN patients and 71% of CALND patients. The liquids in the axillary drains were also fluorescent in 71% of patients with CALND. No statistical significance was observed between the ICG injection groups. The association between compressive fluorescent and the presence of fluorescence in the axillary drains is significant in the pre-operative subgroup and in the whole group. Conclusion: Our research demonstrates that lymphatic leaks aid in the development of seromas and calls into question the effectiveness of the ligatures and/or cauterizations used during surgery. A prospective, multicentric, randomized trial should be conducted to verify the efficacy of this approach.

Lymphatic Alterations Under Tattoos: Preliminary Reports of One Observational Study.

Background: The number of people within the European population having at least one tattoo has increased notably and with it the number of tattoo-associated clinical complications. The injected inks are known to be removed by the lymphatic vessels and can be found in the draining lymph nodes. Aim of the Study: To report our observations on the lymphatic drainages seen under tattoos using near infrared fluorescence imaging of these lymphatic vessels after the injection of indocyanine green. Material and Methods: Indocyanine green was injected intradermally at the basis of the 20 tattooed area(s) in 19 subjects (nine women and ten men; mean age = 28.6). Ten subjects had only black tattoos (six upper limbs and four lower limbs), five (two upper limbs and three lower limbs) black and white tattoos and five multi-colored tattooed limbs (four lower limbs and one upper limb). Results: The imaging exams revealed alterations in eight individuals, seven of whom had tattoos on their lower limbs. Furthermore, the imaging results showed that the abnormalities might be related to the tattooed limb, the tattoo extent and colour. Conclusion: Alterations of the cutaneous lymphatic channels are frequently observed under tattooed territories. Their causal factors should be more precisely studied in future works and these lymphatic alterations should be considered in tattooed patients when using similar imaging techniques for therapeutic and surgical assessments.

Lymphoscintigraphy as a Therapeutic Guidance Tool Can Improve Manual Lymphatic Drainage for the Physical Treatment of Patients with Upper Limb Lymphedema: Randomized Clinical Trial.

Background: The purpose of this study was to measure the effects of lymphoscintigraphically guided manual lymphatic drainage (LG-MLD) and to compare it with standardized manual lymphatic drainage (St-MLD). Materials and Methods: Fifty-two patients with lymphedema of the upper limb who underwent lymphoscintigraphy were randomly allocated into two groups. Following the phase of physical activity, the control group underwent two phases of St-MLD as the experimental group underwent a first phase of St-MLD followed by a second phase of LG-MLD. Areas of interest were then selected [in particular, dermal backflow (DBF) and axillary lymph nodes (LN)], radioactive activities were quantified for each of these areas. Results: If a first phase of St-MLD increased the LN activity by 28% on average, the findings indicated that for the second phase of DLM, LG-MLD was 19% more efficient than St-MLD in increasing LN activity. If a period of rest does not influence the lymph charge of DBF areas, physical activity leads to an average activity increase of 17%, whereas LG-MLD and St-MLD lead to an activity decrease of 11%. Conclusions: For patients with lymphedema, the findings indicate that MLD can increase the lymphatic flow toward the lymphatic nodes by 28% on average and can decrease the charge in the areas of DBF by 11% on average. Moreover, lymphoscintigraphy can be an important therapeutic tool because LG-MLD significantly increases lymphatic flow by 19% more than St-MLD. Concerning the areas of DBF, the LG-MLD and St-MLD decrease the charge in these areas with the same intensity.

Responsiveness of EQ-5D and SF-6D in patients with early arthritis: results from the ESPOIR cohort.

OBJECTIVES: The revolution of early aggressive treatments for early arthritis (EA) has fuelled the search for better approaches to establishing their cost-utility ratio. The authors aimed to compare the responsiveness of the EQ-5D and the SF-6D in a large prospective cohort of patients with EA. METHODS: EQ-5D and SF-6D utility measures were assessed in 813 patients with EA over 2 years. Responsiveness was analysed by the standardised response mean (SRM) and effect size between baseline and 6, 12 and 24 months for the entire sample and subgroups by disease evolution (increase or decrease in Disease Activity Score for 28 joints). Bootstrap methods were used to estimate 95% CI. RESULTS: The EQ-5D provided larger absolute mean change estimates with greater variance than the SF-6D, whatever the direction of change. At 12 months, the SF-6D was more sensitive to change with improved condition than the EQ-5D: SRM 0.83 (0.82 to 0.84) versus 0.57 (0.56 to 0.58). In contrast, the EQ-5D was more sensitive to change with deteriorated condition than the SF-6D: SRM -0.20 (-0.23 to -0.18) versus -0.11 (-0.14 to -0.08). Results were similar for 6 and 24 months. CONCLUSIONS: The SF-6D was more responsive than the EQ-5D with improved EA condition. Confidence in the relative cost-effectiveness of two treatments would be better with the SF-6D because of its smaller variance. The SF-6D provided more conservative cost-effectiveness ratios than the EQ-5D and may be more appropriate for trials of biological treatments for patients with EA.

Eosinophilic fasciitis (Shulman disease): new insights into the therapeutic management from a series of 34 patients.

OBJECTIVE: To analyse therapeutic management of eosinophilic fasciitis (EF). METHODS: We reviewed 34 adult patients with biopsy-proven EF. Analyses focused on the therapeutic management, including treatment modalities, responses and associated or predictive factors. RESULTS: Thirty-four patients were included with a diagnosis age of 53 (15) years. They were featured by cutaneous manifestations (88%) including morphoea (41%), myalgia (86%) and hypereosinophilia (85%). Thirty-two patients (94%) were eligible for treatment evaluation and all received CSs as a first-line therapy. Fifteen patients (47%) received methylprednisolone pulses (MPPs) at treatment initiation and 14 patients (44%) received an immunosuppressive drug (ISD), usually MTX (86%), as a second-line therapy. Complete remission was achieved for 69% of patients, remission with disability 19% and failure 12%. A poor outcome was associated with a diagnosis time delay of >6 months [odds ratio (OR) = 14.7] and the lack of MPPs (OR = 12.9). CONCLUSION: Our study reports new insights into the therapeutic management of EF: (i) CS treatment remains the standard therapy for EF, taken alone or in association with an ISD; (ii) MPPs at initiation of treatment are associated with a better outcome and a lower need of ISD use; (iii) an ISD, usually MTX, might be useful as a second-line therapy, mainly in patients with morphoea-like lesions. Naturally, these practical conclusions should be confirmed by a prospective and multicentre study.

Lymphoscintigraphic Investigations for Axillary Web Syndromes.

Background: Axillary web syndrome (AWS) is a frequent complication after surgery for breast cancer, but its lymphatic involvement is not definitively established. Here we report the results of lymphoscintigraphic investigations in patients with AWS. Methods and Results: We conducted a retrospective, single-center review of lymphoscintigraphic investigations performed in 46 patients with AWS that was either clinically obvious or suspected. Of this group, 23 patients had two investigations with a mean interval of 19 weeks between them (range, 6-98 weeks). Results of the lymphoscintigraphic investigations, which were performed according to a well-standardized protocol, were classified into four patterns: normal; functional lymphatic insufficiency only (no lymphatic vascular morphologic abnormality); lymphovascular blockade without collateralization; and vascular collateralization and/or dermal backflow. Of the 46 patients, on the first lymphoscintigraphic investigation, four (8.6%) had a normal pattern, seven (15.2%) had functional lymphatic insufficiency only, four (8.6%) had lymphovascular blockade without collateralization, and 31 (67.3%) had vascular collateralization and/or dermal backflow. Among patients who underwent two investigations, four of the five who had only functional lymphatic insufficiency at the first investigation had developed vascular collateralization and/or dermal backflow by the second. The three patients who had lymphovascular blockade without collateralization at the first examination had also progressed to collateralization and/or dermal backflow at the second. None of the 15 patients who initially had vascular collateralization and/or dermal backflow showed any reversal at the second examination. Conclusions: Our analysis confirms the lymphatic nature of AWS and shows the lymphoscintigraphic patterns and evolutions of the lymphatic lesions with potential therapeutic implications. The retrospective review of our database is approved by the institutional ethics committee under number 2048.

Use of fluorescence imaging during lymphatic surgery: A Delphi survey of experts worldwide.

BACKGROUND: Fluorescence imaging with indocyanine green is increasingly used during lymphedema patient management. However, to date, no guidelines exist on when it should and should not be used or how it should be performed. Our objective was to have an international panel of experts identify areas of consensus and nonconsensus in current attitudes and practices in fluorescence imaging with indocyanine green use during lymphedema surgery patient management. METHODS: A 2-round Delphi study was conducted involving 18 experts in the use of fluorescence imaging during lymphatic surgery, all asked to vote on 49 statements on patient preparation and contraindications (n = 7 statements), indocyanine green dosing and administration (n = 10), fluorescence imaging uses and potential advantages (n = 16), and potential disadvantages and training needs (n = 16). RESULTS: Consensus ultimately was reached on 40/49 statements, including consistent consensus regarding the value of fluorescence imaging with indocyanine green in almost all facets of lymphedema patient management, including early detection, assessing disease extent, preoperative work-up, surgical planning, intraoperative guidance, monitoring short- and longer-term outcomes, quality control, and resident training. All experts felt it was very safe, while 94% felt it should be part of routine care and that indocyanine green was superior to colored dyes and ultrasound. Nonetheless, there also was consensus that limited high-quality evidence remains a barrier to its widespread use and that patients should still be provided with specific information and asked to sign specific consent for both fluorescence imaging and indocyanine green. CONCLUSION: Fluorescence imaging with or without indocyanine green appears to have several roles in lymphedema prevention, diagnosis, assessment, and treatment.
