Abstract
BACKGROUND There is paucity of data on how gender impacts melanoma prognosis in pediatric and adolescent patients. OBJECTIVES This study explores gender differences in presentation and survival among pediatric and adolescent patients with melanoma. METHODS The National Cancer Database 2004-2018 was queried for cases of primary invasive cutaneous melanoma in pediatric and adolescent patients (birth to 21 years) for a retrospective cohort study. RESULTS Of the 4645 cases, 63.4% were female. Median Breslow depth was 1.05 mm for males (interquartile range 0.50-2.31) and 0.80 mm for females (interquartile range 0.40-1.67; P < .001). Trunk was the most common primary site for females (34.3%) and males (32.9%). More females than males were diagnosed with stage I disease (67.8% vs 53.6%). Males had higher rates of regional lymph node positivity (27.9% vs 18.1%; P < .001) and ulceration (17.1% vs 11.4%; P < .001). Five-year overall survival was 95.9% for females and 92.0% for males (P < .001). After adjusting for confounders, male gender independently increased mortality risk (reference: females; adjusted hazard ratio 1.57; 95% confidence interval 1.32-1.86). LIMITATIONS Retrospective study. CONCLUSION Males exhibited more aggressive pathologic features including greater Breslow thickness and higher ulceration and lymph node positivity rates. Male gender independently increased mortality risk.

Embryonic cerebrospinal fluid influence in the subependymal neurogenic niche in adult mouse hippocampus. Tissue Cell 2023; 82:102120.

Abstract
The adult mouse hippocampal neurogenic niche is a complex structure which is not completely understood. It has mainly been related to the Subgranular layer of the dentate gyrus; however, as a result of differential neural stem cell populations reported in the subventricular zone of the lateral ventricle and associated with the hippocampus, the possibility remains of a multifocal niche reproducing developmental stages. Here, using a set of molecular markers for neural precursors, we describe in the adult mouse brain hippocampus the existence of a disperse population of neural precursors in the Subependymal Zone, the Dentate Migratory Stream and the hilus; these display dynamic behaviour compatible with neurogenesis. This supports the idea that the adult hippocampal niche cannot be restricted to the dentate gyrus subgranular layer. In other neurogenic niches such as the Subventricular Zone, a functional periventricular dependence has been shown due to the ability to respond to embryonic cerebro-spinal fluid. In this study, we demonstrate that neural precursors from the three areas studied (Sub-ependymal Zone, Dentate Migratory Stream and hilus) are able to modify their behaviour by increasing neurogenesis in a locally differential manner. Our results are compatible with the persistence in the adult mouse hippocampus of a neurogenic niche with the same spatial structure as that seen during development and early postnatal stages.

Abstract
Melanoma in Black patients carries a poor prognosis. Due to its rarity, melanoma in this population has not been well characterized. This study evaluates survival predictors in Black patients with melanoma. This was a retrospective cohort study of Black patients with cutaneous melanoma from the National Cancer Database 2004-2018. Of the 2464 cases, melanoma was more common among females than males (57.1% vs. 42.9%, p < .001). Median Breslow depth was 1.8 mm (interquartile range 0.4-4.4). Lower extremities were the most common location (52.8%), followed by upper extremities (13.1%) along with otherwise specified/overlapping/other (13.1%), then by trunk (11.8%), and lastly head and neck (9.2%). Stage at diagnosis was I (30.7%), II (27.5%), III (24.1%), and IV (17.7%). Ulceration was observed in 41.4% of lesions. Acral lentiginous melanoma (ALM) was the most common specific histologic subtype (20.3%), followed by superficial spreading melanoma (9.4%). After adjusting for confounders, higher stages and primary site on the head and neck were the strongest independent predictors of worse overall survival. Melanoma in Black patients is most likely to appear on the lower extremities. A large portion (41.8%) presented with stage III or IV disease. ALM was the most common specific histologic subtype.

Abstract
Introduction Hidradenitis suppurativa (HS) can significantly impact patients' relationships. Methods Using an anonymous electronic survey, we aimed to determine what aspects of sexual relationships are affected by HS discomfort and patients' reluctance to discuss HS with their partner. Results Among the 873 participants, 60.9% reported that some aspect of their relationship was affected by HS discomfort, with the greatest being their sexual encounters with spouse (49.1%). Furthermore, 43.0% (320) of participants reported feeling reluctant to discuss HS with their spouse/significant other, with the more common reason being fear of partner seeing boils and scars (84.7%). Multiple aspects of relationships can be affected by HS such as sexual encounters, overall relationship, and finding a relationship. Additionally, several communication barriers are present, such as fear of partner seeing boils and scars, partner thinking they had an infection such as a sexually transmitted disease, and fear of bloody or malodorous drainage, among others. The presence of anogenital pain, Hurley stage, gender, and age significantly affect these findings. Conclusion Addressing HS-related relationship disturbances should be included in HS management.

Abstract
The waxing-and-waning nature of hidradenitis suppurativa (HS), complex treatment plans, along with variable responsiveness to therapy, can create management challenges for patients. In this pilot cross-over randomized controlled trial, we aim to evaluate the effectiveness a HS-written action plan (HSWAP) on patient disease understanding and confidence in recognizing flares and adjusting management. Participants were randomized into a pre-crossover control group that received a verbal consultation (VC)-only, and an intervention group which received the VC + HSWAP. The pre-crossover control group then crossed over (post-crossover control) to also receive the VC + HSWAP (ClinicalTrials.gov Identifier: NCT04600375). Patient comprehension of their disease and management steps was high after both a thorough VC and HSWAPs. However, the majority of patients prefer receiving both a VC and a HSWAP. After the addition of the HSWAP, pre-crossover control group patients' understanding and confidence of their disease and management plan increased across all surveyed questions.

Abstract
Hidradenitis suppurativa (HS) is a chronic and often debilitating inflammatory condition characterized by frequent nodules, abscesses, sinus tracts, and scars impacting the intertriginous areas. Many patients with HS often report limited treatment success and symptom coverage with conventional therapies. Recent studies have reported the widespread use of complementary and alternative medicine (CAM) among patients with HS. In this study, our aim was to examine current physician practice patterns, opinions, and comfort with recommending CAM. Our results indicate that provider comfort and opinions on CAM varied based on the provider's experiences, demographics, and the CAM modality itself. Overall, nearly two-thirds (n = 30, 61.2%) of respondents agreed that CAM and conventional medicine were more effective together than either alone. Meanwhile, 44.9% (n = 22) of respondents routinely recommend CAM while 64.6% (n = 31) of respondents reported that they are routinely asked about CAM. The majority (n = 41, 83.7%) of respondents indicated a lack of scientific evidence in the medical literature as a barrier to recommending CAM along with efficacy concerns (n = 34, 69.4%) and ability to recommend reputable CAM products (n = 32, 65.3%) and practitioners (n = 32, 65.3%). Future investigations are warranted to establish a better understanding of the efficacy and benefit of CAM methods in conjunction with conventional methods.

Abstract
BACKGROUND Physician burnout is a common problem that can have negative ramifications for both physicians and patients. Lack of effective coping mechanisms decreases resilience, which can lead to burnout, and women may be particularly vulnerable. OBJECTIVE We aimed to evaluate resilience by generation among professionals in dermatology. We hope to gain a better understanding of the plasticity of resilience traits to identify modifiable resilience components. METHODS Attendees of the 2020 Women's Dermatological Society Forum were asked to complete an 80-item questionnaire evaluating eight characteristics of resilience. Each participant received scores electronically, and attendees were invited to anonymously submit scores, job category (physician or industry), and birth year and/or generation category. Participants who provided scores and were part of the millennial generation (born 1980-1994; ages 26-40 years at the time of survey completion), Generation X (born 1965-1979; ages 41-55 years), or baby boomer generation (born 1944-1964; ages 56-76 years) were included. RESULTS Of the 67 participants meeting the inclusion criteria, 96.7% were women and 3.3% were men, 69.4% were physicians and 30.6% were industry representatives. Millennials accounted for 43.3%, Generation X for 35.8%, and baby boomers for 20.9% of the study participants. There was a significant difference among the three generations for mean scores on rumination (p = .0071) and flexibility (p = .0005), with scores becoming more ideal for older generations. There was no significant difference among generations for other resilience or burnout indicators, including emotional inhibition, toxic achieving, avoidance coping, perfect control, detached coping, and sensitivity. CONCLUSION Resilience traits such as rumination and flexibility differed by generation, with the most favorable scores occurring in the oldest cohort, suggesting that some resilience traits may be malleable and improve with age or be inherently affected by environment during development. Health care professionals may benefit from engaging in activities that enhance malleable resilience traits and improve the ability to manage work-related stressors.

Abstract
While dietary triggers have been investigated in acne and other inflammatory follicular dermatoses, there is a paucity of data on diet and hidradenitis suppurativa (HS). We sought to identify exacerbating and alleviating foods in HS patients. An anonymous survey was distributed via HS Facebook support groups and in person at HS specialty clinics. Participants were asked to select all that apply from a list to indicate foods that worsen and make HS better including sweet foods, breads and pasta, red meat, chicken, fish, canned foods, fruits, vegetables, dairy, high-fat foods, I do not know, and no. Only 12.0% (n = 89/744) identified alleviating foods while 32.6% (n = 237/728) identified HS-symptom-exacerbating foods. The most commonly reported exacerbating foods were sweets (67.9%), bread/pasta/rice (51.1%), dairy (50.6%), and high-fat foods (44.2%). The most commonly reported alleviating foods included vegetables (78.7%), fruit (56.2%), chicken (51.7%), and fish (42.7%). Further studies are required to evaluate the mechanistic links between diet and HS. HS patients may benefit from receiving dietary counseling as part of a comprehensive HS management plan.

Abstract
Background Hidradenitis suppurativa (HS) is a chronic inflammatory disorder that primarily affects women of childbearing age. There is a paucity of data on HS disease activity during menstruation, pregnancy, and menopause and the potential impact of HS on the method of delivery. Objective We aimed to characterize the natural history of HS symptoms during menses, pregnancy, and menopause. We also sought to evaluate the potential impact of HS on delivery method and whether there were delivery-related healing complications unique to women with HS. Methods An anonymous survey was distributed via social media to international HS support groups and patients at three HS specialty clinics in North America. Responses were collected from March to July 2019. Results A total of 279 respondents answered questions on disease changes during pregnancy. Menstruation caused worsening of HS symptoms in 76.7%, no change in 22.2%, and improvement in 1.1%. During pregnancy, the distribution between symptoms worsening (34.8%), having no change (28.7%), and improving (36.6%) was relatively even. After menopause, participants typically reported either worsening (39.5%) or no change (44.2%) in HS symptoms. Among respondents with anogenital HS involvement who delivered vaginally, 3.1% believed that HS interfered with vaginal delivery (VD), and 23.5% believed that VD caused an HS flare. Cesarean section (C-section) delivery was reported by 44.2% of participants. Ten participants reported that they were advised by their doctor to have a C-section instead of a VD because of severe anogenital HS. Of those who underwent a C-section, 33.9% reported that HS interfered with incision healing, and 51.2% reported developing new HS lesions in their C-section scar. Conclusion To our knowledge, this is the first study describing the potential influence of HS on a patient’s method of delivery. Multidisciplinary collaboration plays a pivotal role in developing individualized treatment and birth plans for pregnant women with HS.

Abstract
Background Many studies have shown that Staphylococcus aureus is a leading cause of both community onset and hospital onset bloodstream infections. However, relatively little is known about the occurrence and outcome of S. aureus bacteremia in sub-Saharan Africa. A previous report indicated that S. aureus accounts for 16% of community onset and 6% of hospital onset bloodstream infections at Aga Khan University Hospital Nairobi (AKUHN). Data about the etiology of S. aureus bacteremia in sub-Saharan Africa will help optimize recognition and treatment. This study was performed in order to understand the etiologies and risk factors for S. aureus bacteremia in a sub-Saharan location. Materials and methods A review of the electronic record of laboratory results from September 2010 through December 2018 identified 201 patients seen at AKUHN with S. aureus bacteremia. The source and/or focus of infection was identified and in-hospital mortality was determined. Cases with bacteremia after three days of hospitalization were considered hospital acquired. Community onset cases were divided into community acquired and health care associated. Results Most cases (71%; 143/201) were community onset, but only 41% (83/201) of these cases were community acquired. The most commonly identified foci of infection for community acquired bacteremia were musculoskeletal (25%; 21/83) and skin and soft tissue (24%; 20/83). The majority of health care associated (70%; 40/57) and hospital acquired cases (74%; 43/58) were associated with invasive vascular devices, with peripheral IVs being the most common for hospital acquired and dialysis catheters being the most common for health care associated infections. In-hospital mortality rates were 23% (19/83) for community acquired, 19% (11/57) for health care associated and 33% (19/58) for hospital acquired infections. Conclusion Invasive vascular devices were associated with a substantial portion of cases of S. aureus bacteremia and provide an important target for infection control efforts.

Abstract
Injection site reactions with biologic medications are encountered with variable frequency. Although there is no clear definition, they commonly manifest with pain and irritation at the injection site. Previously proposed reaction classification systems may be impractical or insufficient, and more intuitive nomenclature may benefit clinical dermatologists and patients. Negative injection experiences (NIE) are common reasons for biologic medication nonadherence. Here we provide clinical classifications and recommendations for mitigating these reactions. We categorized NIEs into the following: (a) physical, due to the needle and injection process, (b) irritant, related to properties of the injected solution, and (c) allergic, both immediate and delayed.

Abstract
AIM It has been suggested that the repetitive transcranial magnetic stimulation could be useful as a non-pharmacological treatment for spasticity. The aim of this study was to evaluate the clinical and neurophysiological effects of high-frequency intermittent theta burst stimulation (iTBS) on lower limb spasticity in patients with relapsing multiple sclerosis in a randomized, double-blind placebo controlled trial. PATIENTS AND METHODS Seventeen patients in the remitting phase of the disease were randomly allocated to sham or magnetic therapy group and underwent iTBS over contralateral motor cortex of the most affected leg once a day for two weeks. Each session consisted of 10 bursts containing three pulses at 50 Hz repeated at 200 ms intervals (5 Hz) every 10 s for a total of 600 stimuli. The iTBS effect was assessed by using clinical (such as the Modified Ashworth Scale) and neuro-physiological (H/M amplitude ratio and cortical silent period duration) parameters. RESULTS Two-week iTBS over motor cortex of the most affected leg did not produce any significant clinical effect on spasticity. However, it decreases the H/M amplitude ratio and increases duration of cortical silent period but not significantly, in patients with relapsing multiple sclerosis. CONCLUSION The stimulation protocol used in this study does not have significant therapeutic effect. Therefore, we do recommend further studies as neurophysiological changes were evident.

Abstract
The purpose of this work is to evaluate radiation doses to the lens of urologists during interventional procedures and to compare them with values measured during interventional radiology, cardiology and vascular surgery. The measurements were carried out in a surgical theatre using a mobile C-arm system and electronic occupational dosimeters (worn over the lead apron). Patient and staff dose measurements were collected in a sample of 34 urology interventions (nephrolithotomies). The same dosimetry system was used in other medical specialties for comparison purposes. Median and 3rd quartile values for urology procedures were: patient doses 30 and 40 Gy cm(2); personal dose equivalent Hp(10) over the apron (μSv/procedure): 393 and 848 (for urologists); 21 and 39 (for nurses). Median values of over apron dose per procedure for urologists resulted 18.7 times higher than those measured for radiologists and cardiologists working with proper protection (using ceiling suspended screens) in catheterisation laboratories, and 4.2 times higher than the values measured for vascular surgeons at the same hospital. Comparison with passive dosimeters worn near the eyes suggests that dosimeters worn over the apron could be a reasonable conservative estimate for ocular doses for interventional urology. Authors recommend that at least the main surgeon uses protective eyewear during interventional urology procedures.

Abstract
The purpose of this paper is to report a set of experimental values of patient and staff doses in a cardiac catheterisation laboratory using the range of radiographic and geometric parameters from routine clinical practice. The data obtained will be available for validation of Monte Carlo calculations and for training purposes. They will also help optimise radiation protection for patients and staff. Experimental measurements were made with an anthropomorphic phantom, and a monoplane flat detector-based X-ray system was used for interventional cardiology procedures. Standard operational protocols used in clinical practice were applied. Around 1000 patient dose and 5000 staff dose values were measured for different operational conditions (angulations, distances, collimation and wedge filter, magnification, phantom thicknesses, using Copper absorber, etc.). Uncertainties were also estimated. Increase factors of 3-10 for patients and staff doses were measured for the different C-arm angulations.

Abstract
The purpose of this article is to estimate lens doses using over apron active personal dosemeters in interventional catheterisation laboratories (cardiology IC, neuroradiology IN and radiology IR) and to investigate correlations between occupational lens doses and patient doses. Active electronic personal dosemeters placed over the lead apron were used on a sample of 204 IC procedures, 274 IN and 220 IR (all performed at the same university hospital). Patient dose values (kerma area product) were also recorded to evaluate correlations with occupational doses. Operators used the ceiling-suspended screen in most cases. The median and third quartile values of equivalent dose Hp(10) per procedure measured over the apron for IC, IN and IR resulted, respectively, in 21/67, 19/44 and 24/54 µSv. Patient dose values (median/third quartile) were 75/128, 83/176 and 61/159 Gy cm(2), respectively. The median ratios for dosemeters worn over the apron by operators (protected by the ceiling-suspended screen) and patient doses were 0.36; 0.21 and 0.46 µSv Gy(-1) cm(-2), respectively. With the conservative approach used (lens doses estimated from the over apron chest dosemeter) we came to the conclusion that more than 800 procedures y(-1) and per operator were necessary to reach the new lens dose limit for the three interventional specialties.

Abstract
The purpose of this paper is to test the appropriateness of OSL and electronic dosemeters to estimate eye lens doses at interventional cardiology environment. Using TLD as reference detectors, personal dose equivalent was measured in phantoms and during clinical procedures. For phantom measurements, OSL dose values resulted in an average difference of -15 % vs. TLD. Tests carried out with other electronic dosemeters revealed differences up to ±20 % versus TLD. With dosemeters positioned outside the goggles and when TLD doses were >20 μSv, the average difference OSL vs. TLD was -9 %. Eye lens doses of almost 700 μSv per procedure were measured in two cases out of a sample of 33 measurements in individual clinical procedures, thus showing the risk of high exposure to the lenses of the eye when protection rules are not followed. The differences found between OSL and TLD are acceptable for the purpose and range of doses measured in the survey.

Abstract
OBJECTIVES To analyze if the true number of BCG instillations applied in non-muscle invasive bladder tumors has any influence on their prognosis as well as other tumor and clinical characteristics: age, sex, different protocols, BCG dose, whether primary or recurrent, solitary or multiple, tumor size G3 or Cis. PATIENTS AND METHODS A total of 324 high grade NMIBC (15 TaG3, 184 T1G3, 125 Cis) out of 1491 cases included in the CUETO database were analyzed. Following 6 post transurethral resection (RTU) BCG instillations, the patients were scheduled to receive one instillation every two weeks (3-6 times), for a total of 9-12 instillations. One third of the dose (27 mg) (112 cases) or total dose of 81 mg (212 cases). Mean follow-up was 59.6 months. Statistical Analysis: Kaplan-Meier, Cox-regression (uni-multivariate). RESULTS A higher level of recurrence (p = 0.032) and progression (P = .013) risk as well as worse Ca-specific survival (P = .005) were obtained if there were fewer than 12 instillations with the Kaplan-Meier and Cox-regression multivariate analysis. A 27 mg (P = .008) dosage and being a female (P < .001) were independent factors for a higher recurrence risk, but not for progression or Ca-specific survival. The remaining characteristics studied were not statistically significant. CONCLUSIONS In accordance with the results obtained, we can conclude that the number of BCG instillations applied has some influence on the outcome of high grade NMIBC. The optimum number of instillations as well as their time of application must still be determined. A dose of 27 mg and being a female are predictive factors of recurrence.

Abstract
BACKGROUND AND PURPOSE Radiation exposure from neurointerventional procedures can be substantial, with risk of radiation injuries. We present the results of a follow-up program applied to potential skin injuries in interventional neuroradiology based on North American and European guidelines. MATERIALS AND METHODS The following guidelines approved in 2009 by SIR and CIRSE have been used over the last 2 years to identify patients with potential skin injuries requiring clinical follow-up: peak skin dose >3 Gy, air kerma at the patient entrance reference point >5 Gy, kerma area product >500 Gy · cm(2), or fluoroscopy time >60 minutes. RESULTS A total of 708 procedures (325 in 2009 and 383 in 2010) were included in the study. After analyzing each dose report, 19 patients (5.9%) were included in a follow-up program for potential skin injuries in 2009, while in 2010, after introducing several optimizing actions and refining the selection criteria, only 4 patients (1.0%) needed follow-up. Over the last 2 years, only 3 patients required referral to a dermatology service. CONCLUSIONS The application of the guidelines to patient radiation dose management helped standardize the selection criteria for including patients in the clinical follow-up program of potential skin radiation injuries. The peak skin dose resulted in the most relevant parameter. The refinement of selection criteria and the introduction of a low-dose protocol in the x-ray system, combined with a training program focused on radiation protection, reduced the number of patients requiring clinical follow-up.

Abstract
The purpose of this work was to develop an automatic management system to archive and analyse the major study parameters and patient doses for fluoroscopy guided procedures performed in cardiology and interventional radiology systems. The X-ray systems used for this trial have the capability to export at the end of the procedure and via e-mail the technical parameters of the study and the patient dose values. An application was developed to query and retrieve from a mail server, all study reports sent by the imaging modality and store them on a Microsoft SQL Server data base. The results from 3538 interventional study reports generated by 7 interventional systems were processed. In the case of some technical parameters and patient doses, alarms were added to receive malfunction alerts so as to immediately take appropriate corrective actions.

Abstract
The south-west lagoon of New Caledonia is a wide semi-open coral reef lagoon bounded by an intertidal barrier reef and bisected by numerous deep inlets. This paper synthesizes findings from the 2000-2008 French National Program EC2CO-PNEC relative to the circulation and the transport of suspended particles in this lagoon. Numerical model development (hydrodynamic, fine suspended sediment transport, wind-wave, small-scale atmospheric circulation) allowed the determination of circulation patterns in the lagoon and the charting of residence time, the later of which has been recently used in a series of ecological studies. Topical studies based on field measurements permitted the parameterisation of wave set-up induced by the swell breaking on the reef barrier and the validation of a wind-wave model in a fetch-limited environment. The analysis of spatial and temporal variability of suspended matter concentration over short and long time-scales, the measurement of grain size distribution and the density of suspended matter (1.27 kg l(-1)), and the estimation of erodibility of heterogeneous (sand/mud, terrigenous/biogenic) soft bottoms was also conducted. Aggregates were shown to be more abundant near or around reefs and a possible biological influence on this aggregation is discussed. Optical measurements enabled the quantification of suspended matter either in situ (monochromatic measurements) or remotely (surface spectral measurements and satellite observations) and provided indirect calibration and validation of a suspended sediment transport model. The processes that warrant further investigation in order to improve our knowledge of circulation and suspended sediment transport in the New Caledonia lagoon as well as in other coral reef areas are discussed, as are the relevance and reliability of the numerical models for this endeavour.

Abstract
We investigated the spatial distribution of adult and juvenile coral assemblages in the southwestern lagoon of New Caledonia, from disturbed fringing reefs within bays, to oceanic barrier reefs. Generic richness, abundance, and percent cover were highly variable at this scale, but no clear cross-shelf gradient was found. Rather, community composition was more related to reef biotopes. Correlations and canonical correspondence analyses revealed that composition and abundance of coral assemblages were related to substrate types (cover of turf algae and cover of encrusting coralline algae), but not to water quality or metal concentrations in sediments. We found a strong relationship between juvenile and adult distribution for all dominant genera, which suggests that recruitment processes are also a major factor structuring these populations. The densities of juveniles and their proportion in the coral assemblages were relatively low, which implies that replenishment capacities and potential for recovery are probably limited for these reefs.

Abstract
The design of a national dose protocol for interventional radiology has been one of the tasks during the European SENTINEL Coordination Action. The present paper describes the pilot experience carried out in cooperation with the Spanish Society on Vascular and Interventional Radiology (SERVEI). A prospective sample of procedures was initially agreed. A common quality control of the X-ray systems was carried out, including calibration of the air kerma area product (KAP) meters. Occupational doses of the radiologists involved in the survey were also included in the survey. A total of 10 Spanish hospitals with interventional X-ray units were involved. Six hundred and sixty-four patient dose data were collected from 397 diagnostic and 267 therapeutic procedures. Occupational doses were evaluated in a sample of 635 values. The obtained KAP median/mean values (Gy.cm2) for the gathered procedures were: biliary drainage (30.6/68.9), fistulography (4.5/9.8), lower limb arteriography (52.2/60.7), hepatic chemoembolisation (175.8/218.3), iliac stent (45.9/73.2) and renal arteriography (39.1/59.8). Occupational doses (mean monthly values, in mSv) were 1.9 (over apron); 0.3 (under apron) and 4.5 (on hands). With this National experience, a protocol was agreed among the SENTINEL partners to conduct future similar surveys in other European countries.
