ABSTRACT
Kimura disease (KD) is a rare, chronic angiolymphoproliferative inflammatory disease appearing to be mostly restricted to the skin and soft tissue. Cutaneous involvement of KD includes head and/or neck nodules showing suggestive histological features, frequently associated with an atopic dermatitis-like or prurigo-like presentation. KD is challenging to treat, with high rate of recurrence using current therapeutic strategies. Evidence for involvement of a T-helper type 2 (Th2) immune response in KD pathogenesis has been found in previous studies. Consequently, this study aimed to determine the efficacy and safety of dupilumab, a human monoclonal antibody that inhibits signalling of key Th2 cytokines, interleukin (IL)-4 and IL-13, within a single-centre cohort of patients with cutaneous KD. Two adults with a diagnosis of refractory (failure of at least one treatment line) cutaneous-restricted KD based on clinical, biological, histological, molecular and imaging findings received dupilumab for KD, and showed dramatic response with a good safety profile.

INTRODUCTION: Software to predict the impact of aging on physical appearance is increasingly popular. But it does not consider the complex interplay of factors that contribute to skin aging. OBJECTIVES: To predict the +15-year progression of clinical signs of skin aging by developing Causal Bayesian Belief Networks (CBBNs) using expert knowledge from dermatologists. MATERIAL AND METHODS: Structures and conditional probability distributions were elicited worldwide from dermatologists with experience of at least 15 years in aesthetics. CBBN models were built for all phototypes and for ages ranging from 18 to 65 years, focusing on wrinkles, pigmentary heterogeneity and facial ptosis. Models were also evaluated by a group of independent dermatologists ensuring the quality of prediction of the cumulative effects of extrinsic and intrinsic skin aging factors, especially the distribution of scores for clinical signs 15 years after the initial assessment. RESULTS: For easiness, only models on African skins are presented in this paper. The forehead wrinkle evolution model has been detailed. Specific atlas and extrinsic factors of facial aging were used for this skin type. But the prediction method has been validated for all phototypes, and for all clinical signs of facial aging. CONCLUSION: This method proposes a skin aging model that predicts the aging process for each clinical sign, considering endogenous and exogenous factors. It simulates aging curves according to lifestyle. It can be used as a preventive tool and could be coupled with a generative AI algorithm to visualize aging and, potentially, other skin conditions, using appropriate images.

BACKGROUND AND OBJECTIVES: Spinal cord metastasis arising from an intracranial glioblastoma is a rare and late event during the natural course of the disease. These pathological entities remain poorly characterized. This study aimed to identify and investigate the timeline, clinical and imaging findings, and prognostic factors of spinal cord metastasis from a glioblastoma. METHODS: Consecutive histopathological cases of spinal cord metastasis from glioblastomas in adults entered in the French nationwide database between January 2004 and 2016 were screened. RESULTS: Overall, 14 adult patients with a brain glioblastoma (median age 55.2 years) and harboring a spinal cord metastasis were included. The median overall survival as 16.0 months (range, 9.8-22.2). The median spinal cord Metastasis Free Survival (time interval between the glioblastoma diagnosis and the spinal cord metastasis diagnosis) was 13.6 months (range, 0.0-27.9). The occurrence of a spinal cord metastasis diagnosis greatly impacted neurological status: 57.2% of patients were not ambulatory, which contributed to dramatically decreased Karnofsky Performance Status (KPS) scores (12/14, 85.7% with a KPS score ≤ 70). The median overall survival following spinal cord metastasis was 3.3 months (range, 1.3-5.3). Patients with a cerebral ventricle effraction during the initial brain surgery had a shorter spinal cord Metastasis Free Survival (6.6 vs 18.3 months, p = 0.023). Out of the 14 patients, eleven (78.6%) had a brain IDH-wildtype glioblastoma. CONCLUSIONS: Spinal cord metastasis from a brain IDH-wildtype glioblastoma has a poor prognosis. Spinal MRI can be proposed during the follow-up of glioblastoma patients especially those who have benefited from cerebral surgical resection with opening of the cerebral ventricles.

BACKGROUND: At present there is no standard nomenclature for describing the diversity of human constitutive skin colour. OBJECTIVES: To develop a standard nomenclature to describe human constitutive skin colour. METHODS: Monthly focus group discussions were carried out among a multidisciplinary group of specialists over a 7-month period. Topics covered were (i) limitations and unmet needs of current nomenclature(s) pertaining to human cutaneous diversity, (ii) practical considerations about the function and role of any proposed nomenclature pertaining to human cutaneous diversity, (iii) review of the cellular basis and current molecular genetic understanding of variation in human skin pigmentation and (iv) in vivo methods to evaluate human skin pigmentation. In addition, a preliminary review of the published literature was undertaken to collate data on published skin reflectance measurements, notably melanin index values for well-referenced human populations. RESULTS: We developed a five-point scale to describe the full spectrum of human constitutive skin colour, termed the Eumelanin Human Skin Colour Scale. The nomenclature of the scale uses eumelanin, the dominant chromophore of human skin, as a central descriptive word. The categories of the scale (nomenclature and melanin index values) are eumelanin low (EML), < 25; eumelanin intermediate low (EMIL), 25 to < 50; eumelanin intermediate (EMI), 50 to < 75; eumelanin intermediate high (EMIH), 75 to < 100; and eumelanin high (EH), ≥ 100. CONCLUSIONS: The Eumelanin Human Skin Colour Scale enables the complete range of human constitutive skin colour to be described in an objective, equitable and understandable manner. In future, this scale can be used as the basis for developing other scales that address the specific functional aspects of human skin, such as response to ultraviolet radiation.

INTRODUCTION: Intra-arterial therapy is an effective way of performing chemotherapy or radiation therapy in patients with primary liver cancer (i.e. hepatocellular carcinoma). Although this minimally invasive approach is now an established treatment option, support tools for pre-operative planning and intra-operative assistance might be helpful. MATERIAL AND METHODS: We developed an approach for semi-automatic segmentation of computed tomography angiography images of the main arterial branches (required for access path to the treatment site), automatic segmentation of the liver, arterial and venous tree, and interactive segmentation of the tumors (required for procedure-specific planning). This approach was then integrated into a liver-specific workflow within EndoSize® solution, a planning software for endovascular procedures. The main branches extraction approach was qualitatively evaluated inside the software, while the automatic segmentation methods were quantitatively assessed. RESULTS: Main branches extraction provides a success rate of 85% (i.e. all arteries correctly extracted) in a dataset of 172 patients. On public databases, a mean DICE of 0.91, 0.47 and 0.92 was obtained for liver, venous and arterial trees segmentation, respectively. CONCLUSIONS: This pipeline is suitable for directly accessing the treatment site, giving anatomic measurements, and visualizing the hepatic trees, liver, and surrounding arteries during the pre-operative planning. ABBREVIATIONS: HCC: hepatocellular carcinoma; TACE: transarterial chemoembolization; SIRT: selective internal radiation therapy; CT: computed tomography; CTA: computed tomography angiography; AMS: superior mesenteric artery; LGA: left gastric artery; RHA: right hepatic artery; LHA: left hepatic artery; rbHA: right branch of the hepatic artery; lbHA: left branch of the hepatic artery; GDA: gastroduodenal artery; VOI: volume of interest; SD: standard deviation; MICCAI: medical image computing and computer assisted interventions; MR: magnetic resonance.

BACKGROUND: Leishmaniases are regularly seen in non-endemic areas due to the increase of international travels. They include cutaneous leishmaniases (CL) and mucocutaneous (MC) caused by different Leishmania species, and visceral leishmaniases (VL) which present with non-specific symptoms. METHODS: We reviewed all consecutive leishmaniasis cases seen between September 2012 and May 2020. The diagnostic strategy included microscopy after May-Grünwald-Giemsa staining, a diagnostic quantitative PCR (qPCR) assay, and species identification based on sequencing of the cytochrome b gene. RESULTS: Eighty-nine patients had a definitive leishmaniasis diagnosis. Nine patients had VL with Leishmania infantum. Eighty patients had CL. Twelve patients acquired CL after trips in Latin America (7 Leishmania guyanensis, 2 Leishmania braziliensis, 2 Leishmania mexicana, and 1 Leishmania panamensis). Species could be identified in 63 of the 68 CLs mainly after travel in North Africa (59%) with Leishmania major (65%), Leishmania tropica/killicki (24%), and L. infantum (11%), or in West Sub-Saharan Africa (32%), all due to L. major. The median day between appearance of the lesions and diagnosis was 90 [range 60-127]. CONCLUSIONS: Our diagnostic strategy allows both positive diagnoses and species identifications. Travelers in West Sub-Saharan Africa and North Africa should be better aware of the risk of contracting leishmananiasis.

Folliculitis decalvans (FD) is a chronic inflammatory disease of unknown aetiology. Although Staphylococcus aureus, frequently found on lesional skin, is thought to play a causal role, the importance of its involvement remains controversial. To examine the role of S aureus, we compared superficial and subepidermal microbiota in 20 FD patients who had S aureus on lesional skin and in 20 healthy controls using culture techniques and genomic identification, before and after an anti-staphylococcal treatment; we also screened for S aureus virulence factors. When present on lesional skin, S aureus colonized non-lesional and subepidermal skin in 80% of cases. These data imply a break in the epidermal barrier integrity and that an abnormal non-lesional skin microbiota persists in FD. S aureus had no superantigenic toxin in 31% of cases and no toxin specificity. Clinical improvement obtained in most cases upon treatment was associated with the disappearance of S aureus in all studied areas, with an incomplete restoration of normal microbiota and a significant increase in negative bacterial samples. This persistent unbalanced, subepidermal microbiota may act as a reservoir of abnormal flora and explain the chronicity of FD, suggesting new avenues of research to restore normal microbiota.

We assessed prognostic factors in relation to OS from progression in recurrent glioblastomas. Retrospective multicentric study enrolling 407 (training set) and 370 (external validation set) adult patients with a recurrent supratentorial glioblastoma treated by surgical resection and standard combined chemoradiotherapy as first-line treatment. Four complementary multivariate prognostic models were evaluated: Cox proportional hazards regression modeling, single-tree recursive partitioning, random survival forest, conditional random forest. Median overall survival from progression was 7.6 months (mean, 10.1; range, 0-86) and 8.0 months (mean, 8.5; range, 0-56) in the training and validation sets, respectively (p = 0.900). Using the Cox model in the training set, independent predictors of poorer overall survival from progression included increasing age at histopathological diagnosis (aHR, 1.47; 95% CI [1.03-2.08]; p = 0.032), RTOG-RPA V-VI classes (aHR, 1.38; 95% CI [1.11-1.73]; p = 0.004), decreasing KPS at progression (aHR, 3.46; 95% CI [2.10-5.72]; p < 0.001), while independent predictors of longer overall survival from progression included surgical resection (aHR, 0.57; 95% CI [0.44-0.73]; p < 0.001) and chemotherapy (aHR, 0.41; 95% CI [0.31-0.55]; p < 0.001). Single-tree recursive partitioning identified KPS at progression, surgical resection at progression, chemotherapy at progression, and RTOG-RPA class at histopathological diagnosis, as main survival predictors in the training set, yielding four risk categories highly predictive of overall survival from progression both in training (p < 0.0001) and validation (p < 0.0001) sets. Both random forest approaches identified KPS at progression as the most important survival predictor. Age, KPS at progression, RTOG-RPA classes, surgical resection at progression and chemotherapy at progression are prognostic for survival in recurrent glioblastomas and should inform the treatment decisions.

A growing literature supports maximal safe resection followed by standard combined chemoradiotherapy (i.e. maximal first-line therapy) for selected elderly glioblastoma patients. To assess the prognostic factors from recurrence in elderly glioblastoma patients treated by maximal safe resection followed by standard combined chemoradiotherapy as first-line therapy. Multicentric retrospective analysis comparing the prognosis and optimal oncological management of recurrent glioblastomas between 660 adult patients aged of < 70 years (standard group) and 117 patients aged of ≥70 years (elderly group) harboring a supratentorial glioblastoma treated by maximal first-line therapy. From recurrence, both groups did not significantly differ regarding Karnofsky performance status (KPS) (p = 0.482). Oncological treatments from recurrence significantly differed: patients of the elderly group received less frequently oncological treatment from recurrence (p < 0.001), including surgical resection (p < 0.001), Bevacizumab therapy (p < 0.001), and second line chemotherapy other than Temozolomide (p < 0.001). In multivariate analysis, Age ≥70 years was not an independent predictor of overall survival from recurrence (p = 0.602), RTOG-RPA classes 5-6 (p = 0.050) and KPS at recurrence <70 (p < 0.001), available in all cases, were independent significant predictors of shorter overall survival from recurrence. Initial removal of ≥ 90% of enhancing tumor (p = 0.004), initial completion of the standard combined chemoradiotherapy (p = 0.007), oncological treatment from recurrence (p < 0.001), and particularly surgical resection (p < 0.001), Temozolomide (p = 0.046), and Bevacizumab therapy (p = 0.041) were all significant independent predictors of longer overall survival from recurrence. Elderly patients had substandard care from recurrence whereas age did not impact overall survival from recurrence contrary to KPS at recurrence <70. Treatment options from recurrence should include repeat surgery, second line chemotherapy and anti-angiogenic agents.

Tinea capitis (TC) is a highly contagious fungal infection of the scalp due to dermatophytes in children. To obtain information on the epidemiology of TC in the urban area of Paris, we analysed the microbiological results of 3090 patients seen with suspected TC from October 2010 to September 2015 at Saint Louis hospital, Paris, France. A peak of TC was observed in 3-6 year-old children, followed by a progressive decrease until 16 years of age. Of the 1311 positive cultures, 95% (1246) yielded one of the three anthropophilic species [Trichophyton tonsurans (33.5%), Trichophyton soudanense (38.3%), or Microsporum audouinii (28.2%)]. When considering one TC case per family, we observed a significant increase of T. tonsurans (P = .018) during these 5 years. The increase was more pronounced (P = .0047) in patients of West-African descent (n = 666), and was at the expense of M. audouinii and T. soudanense. On the other hand, the Caribbean patients (n = 85) remained predominantly (72.9%) infected by T. tonsurans. Our results show a better virulence of T. tonsurans over other species as already reported. Since T. tonsurans has not been reported in Africa, the infection of patients of West-African descent probably took place in the Paris area by exchanges with Caribbean patients. This increase of TC due to T. tonsurans was observed in the context of griseofulvin being the only licensed paediatric treatment for TC in France, which should deserve reappraisal because terbinafine may be more efficacious.

BACKGROUND: Cutaneous polyarteritis nodosa (cPAN) is a skin medium vessel neutrophilic arteritis with livedo, nodules, and ulcerations. Macular lymphocytic arteritis (MLA) is a small arteritis with erythematous or pigmented macules and typical histologic features (a lymphocytic infiltrate, concentric fibrin ring, no disruption of the internal elastic lamina). OBJECTIVE: We sought to assess the frequency of clinical and histologic features of MLA in patients with cPAN. METHODS: This was a monocentric retrospective analysis of patients given the diagnosis of cPAN with blinded assessment of skin biopsy specimens. RESULTS: All 35 patients included had an infiltrated livedo, nodules, or both. Ulceration was rare. Erythematous or pigmented lesions were present in 54% of patients. Predominantly lymphocytic arteritis, a paucity of neutrophils, concentric fibrin ring, and absence of internal lamina elastic disruption were present in 60%, 20%, 18%, and 23% of patients, respectively. Median follow-up was 11 years. None of the patients had systemic involvement, and 57% had a complete remission. The incidence of complete remission was not different between patients having a predominant lymphocyte infiltrate or few neutrophils. LIMITATIONS: This was a retrospective, monocentric study without a control group of patients with MLA. CONCLUSIONS: Our data do not favor the classification of cPAN and MLA as distinct entities.

INTRODUCTION: Bleomycin (0.75 g/L)-lidocaine (3.5 g/L)-epinephrine (3.5 mg/L) admixture (BLE) is indicated for keloids treatment. Effect of short-term storage, influence of BLE components and temperature on efficacy and chemical compatibility of bleomycin were studied. METHODS: The stability study of BLE was conducted in polypropylene infusion bags at 4â and 22â over a period of 7 days versus bleomycin diluted alone in normal saline and stored in the same conditions. Active Bleomycin fractions, bleomycin A2 (BA2) and bleomycin B2 (BB2) and inactive demethylbleomycin A2 (DBA2) were analyzed by a validated stability-indicating HPLC method. RESULTS AND DISCUSSION: BA2 and BB2 remained stable for up to 7 days, in both types of bleomycin preparations, whatever the temperature (<10% loss of the initial peak response). In BLE, DBA2 fraction (2.2% at T0) decreased with time. Less degradation was noted with refrigeration (remained % at day 7: 0.86 ± 0.06% at 4â versus 0.43 ± 0.02% at 22â; p = 0.0004). A degradation product (DP) was observed. More significant percentage (of the total of bleomycin fractions) was reached at room temperature (at day 7, 0.97 ± 0.03% at 4â versus 1.41 ± 0.06% at 22â, p = 0.0004). DP attained an identification threshold of 0.5% between the third and fourth days at 4â and between the first and the second days at 22â. CONCLUSION: A maximum of three days storage at 4â and only one day at 22â was approved for BLE.

BACKGROUND: A rare variant of mycosis fungoides (MF), syringotropic MF (STMF) is characterized by a particular tropism of the lymphocytic infiltrate for the eccrine structures, and included in the follicular subtype of MF in the World Health Organization-European Organization for Research and Treatment of Cancer classification of cutaneous lymphomas. OBJECTIVE: We sought to determine the clinicopathologic features and disease course of patients with STMF. METHODS: A retrospective study was conducted to identify patients with STMF from 1998 to 2013. RESULTS: Nineteen patients were included: 15 men and 4 women, mean age 55 years (range, 24-86). Most had multiple lesions (n=16, 84%) with associated alopecia (n=12, 63%) and/or punctuated aspect (n=12, 63%). Palms or soles were involved in 10 cases (53%). Folliculotropism was found in 13 cases (68%). After a median follow-up of 70 months (range, 2-140), 3 patients died, 1 from disease-related death. The 5-year overall and disease-specific survival were 100%. The disease-specific survival was significantly higher than in 54 patients with folliculotropic MF without syringotropism (5-year disease-specific survival, 74%; 95% confidence interval, 58%-94%, P=.02). LIMITATIONS: Retrospective setting is a limitation. CONCLUSIONS: In the spectrum of adnexotropic MF, STMF appears as a distinct entity from follicular MF, with peculiar clinical characteristics and natural history.

OBJECTIVE: The objective of this study was to evaluate the efffectiveness of a titanium vertebral augmentation device (SpineJack system) in terms of back pain, radiological outcomes, and economic burden compared with nonsurgical management (NSM) (bracing) for the treatment of vertebral compression fractures. Complications were also evaluated for both treatment methods. METHODS: A prospective multicenter randomized study was performed at 9 French sites. Patients (n = 100) with acute traumatic Magerl type A1 and A3.1 vertebral fractures were enrolled and randomized to treatment with the SpineJack system or NSM consisting of bracing and administration of pain medication. Participants were monitored at admission, during the procedure, and at 1, 12, and 24 months after treatment initiation. Primary outcomes included visual analog scale back pain score, and secondary outcomes included disability (Oswestry Disability Index [ODI] score), health-related quality of life (EQ-5D score), radiological measures (vertebral kyphosis angle [VKA] and regional traumatic angulation [RTA]), and economic outcomes (costs, procedures, hours of help, and time to return to work). RESULTS: Ninety-five patients were included in the analysis, with 48 in the SpineJack group and 47 in the NSM group. Back pain improved significantly for all participants with no significant differences between groups. ODI and EQ-5D scores improved significantly between baseline and follow-up (1, 12, and 24 months) for all participants, with the SpineJack group showing a larger improvement than the NSM group between baseline and 1 month. VKA was significantly lower (p < 0.001) (i.e., better) in the SpineJack group than in the NSM group at 1, 12, and 24 months of follow-up. There was no significant change over time in RTA for the SpineJack group, but the NSM group showed a significant worsening in RTA over time. SpineJack treatment was associated with higher costs than NSM but involved a shorter hospital stay, fewer medical visits, and fewer hours of nursing care. Time to return to work was significantly shorter for the SpineJack group than for the NSM group. There were no significant differences in complications between the two treatments. CONCLUSIONS: Overall, there was no statistical difference in the primary outcomes between the SpineJack treatment group and the NSM group. In terms of secondary outcomes, SpineJack treatment was associated with better radiological outcomes, shorter hospital stays, faster return to work, and fewer hours of nursing care.
