French guidelines for the management of oral lichen planus (excluding pharmacological therapy).

INTRODUCTION: Oral lichen is a chronic inflammatory disease for which diagnostic management and follow-up are heterogeneous given the absence of specific guidelines in France. Our objective was to develop French multidisciplinary guidelines for the management of oral lichen. MATERIALS AND METHODS: Working groups from the Groupe d'Etude de la Muqueuse Buccale (GEMUB) formulated a list of research questions and the corresponding recommendations according to the "formal consensus" method for developing practice guidelines. These recommendations were submitted to a group of experts and the degree of agreement for each recommendation was assessed by a scoring group. RESULTS: Twenty-two research questions, divided into 3 themes (nosological classification and initial assessment, induced oral lichenoid lesions, and follow-up) resulted in 22 recommendations. Initial biopsy for histology is recommended in the absence of reticulated lesions. Biopsy for direct immunofluorescence is recommended for ulcerated, erosive, bullous types and for diffuse erythematous gingivitis. Management should include a periodontal and dental check-up, and investigation for extra-oral lesions. Hepatitis C testing is recommended only if risk factors are present. Definitions, triggering factors and the management of "induced oral lichenoid lesions" were clarified. Oral lichen must be monitored by a practitioner familiar with the disease at least once a year, using objective tools. CONCLUSION: This formalised consensus of multidisciplinary experts provides clinical practice guidelines on the management and monitoring of oral lichen.

Topical rapamycin versus betamethasone dipropionate ointment for treating oral erosive lichen planus: a randomized, double-blind, controlled study.

BACKGROUND: Although superpotent topical corticosteroids are the first-line treatment for oral erosive lichen planus (OELP), topical rapamycin was found efficient in a previous case series. OBJECTIVES: To compare the efficacy and safety of topical rapamycin and betamethasone dipropionate ointment for OELP in a randomized, double-blind trial. METHODS: Patients were randomized to receive treatment with betamethasone dipropionate ointment 0.05% in Orabase® or topical rapamycin solution (1 mg/mL) on lesions twice daily for 3 months, followed by 3 months of observation. The primary outcome was clinical remission after 3 months of treatment. Secondary outcomes were clinical remission after 1 and 2 months, reduced oral pain and reduced impact on food intake after 3 months, clinical recurrence after treatment withdrawal, and adverse events. RESULTS: During a 4-year period, 76 patients were randomized and 75 received treatment (rapamycin, n = 39; betamethasone, n = 36). At 3 months, 39.4% of patients with betamethasone and 27.3% with rapamycin showed clinical remission (odds ratio 0.68, 95% CI [0.24; 1.89]; P = 0.46). Rates of remission after 1 and 2 months, reduction in pain and impact on food intake after 3 months, were higher with betamethasone than rapamycin. Recurrence of oral erosions was similar between groups. Adverse events occurred in 43.6% of patients with rapamycin (mostly burning sensation, impaired taste) and 27.8% with betamethasone (mostly oral candidiasis). CONCLUSION: Although the study was limited by insufficient recruitment, we did not find any superiority of topical rapamycin over betamethasone dipropionate ointment for OELP. Given the rapid remission and pain improvement in the betamethasone group, it appears that superpotent topical corticosteroids should remain the first-line treatment for OELP.

Prescribers' experience and opinions on antimicrobial stewardship programmes in hospitals: a French nationwide survey.

OBJECTIVES: To assess prescribers' experiences and opinions regarding antimicrobial stewardship programme (ASP) activities. METHODS: A cross-sectional paper-based survey was conducted among prescribers in 27 out of 35 randomly selected large hospitals in France. RESULTS: All 27 investigated hospitals (20 non-university public, 4 university-affiliated and 3 private hospitals) had an ASP and an appointed antibiotic advisor (AA), with a median of 0.9 full-time equivalents per 1000 acute-care beds (IQR 0-1.4). Of the 1963 distributed questionnaires, 920 were completed (46.9%). Respondents were mainly attending physicians (658/918, 71.7%) and medical specialists (532/868, 61.3%). Prescribers identified two main ASP objectives: to limit the spread of resistance (710/913, 77.8%) and to improve patient care and prognosis (695/913, 76.1%). The presence of an AA constituted a core element of ASP (96.2% agreement between answers of ASP leader and respondents). Respondents acknowledged an AA's usefulness especially on therapeutic issues, i.e. choosing appropriate antibiotic (agreement 84.7%) or adapting treatment (89.6%), but less so on diagnostic issues (31.4%). Very few respondents reported unsolicited counselling and post-prescription controls. Three-quarters of prescribers identified local guidelines (692/918, 75.4%). Prescribers did not approve of measures counteracting their autonomy, i.e. automatic stop orders (agreement 23.4%) or pre-approval by AAs (28.8%). They agreed more with educational interventions (73.0%) and clinical staff meetings (70.0%). CONCLUSIONS: Prescribers perceived ASP mainly through its 'on-demand' counselling activities. They preferred measures that did not challenge their clinical autonomy. High levels of antibiotic consumption in French hospitals bring into question the effectiveness of such an approach. However, limited ASP staffing and resources may preclude extended activities.

Salivary scintigraphy for Sjögren's syndrome in patients with xerostomia: A retrospective study.

OBJECTIVES: The value of salivary gland scintigraphy in the diagnosis of Sjögren's syndrome remains controversial. The primary aim of this study was to estimate the diagnostic accuracy of salivary gland scintigraphy in the diagnosis of Sjögren's syndrome among 237 patients with xerostomia. METHODS: We retrospectively compared eight scintigraphy parameters between 106 Sjögren patients and 131 non-Sjögren patients. RESULTS: Seven of the eight parameters were significantly decreased in patients with Sjögren; however, their diagnostic accuracy was low, with areas under the curves (AUCs) ranging from 0.58 (95% CI 0.50-0.65) to 0.63 (95% CI: 0.55-0.70). The prestimulatory oral activity index allowed discrimination between primary and secondary Sjögren's syndrome (AUC 0.73, 95% CI: 0.62-0.84), and the secretion velocity for parotid glands allowed discrimination between patients with Sjögren and burning mouth syndrome (AUC 0.71, 95% CI 0.59-0.82). CONCLUSION: The accuracy of scintigraphy parameters for the diagnosis of Sjögren's syndrome among patients with xerostomia was low; however, some functional indices appeared to assist discrimination between primary and secondary SS patients and between subgroups of patients with different causes of xerostomia.

High-frequency ultrasound quantification of acute radiation dermatitis: pilot study of patients undergoing radiotherapy for breast cancer.

BACKGROUND: Acute radiation dermatitis (ARD) is a frequent complication after breast cancer radiotherapy and is usually assessed by semi-quantitative clinical scores, which may be subject to inter-observer variability. High-frequency ultrasound imaging of the skin can reliably quantify thickness and edema in diseased skin. We aimed to compare the relative increase in dermal thickness of the irradiated zone in breast-cancer patients undergoing radiotherapy, with clinical severity. METHODS: A consecutive series of patients undergoing treatment for breast cancer by lumpectomy and radiotherapy in a 6-month period also underwent clinical and ultrasound evaluation of ARD. RESULTS: We included 34 female patients 17 had grade 1 (group 1), 17 had grade 2 or grade 3 ARD (group 2). The mean relative increase in dermal thickness in irradiated skin (RIDTIS) was greater for group 2 than 1: 0.53 vs 0.29 mm (P=.023). On univariate analysis, ARD was associated with skin phototype, breast volume and RIDTIS, and on multivariable analysis, breast volume and age remained predictive of the disease. CONCLUSION: Patients with more severe dermatitis showed significantly increased dermal thickness. Dermal thickness is a quantitative variable that could help quantify the efficacy of drugs and improve the treatment of this disease in patients undergoing radiotherapy.

Early Low Urinary CXCL9 and CXCL10 Might Predict Immunological Quiescence in Clinically and Histologically Stable Kidney Recipients.

We monitored the urinary C-X-C motif chemokine (CXCL)9 and CXCL10 levels in 1722 urine samples from 300 consecutive kidney recipients collected during the first posttransplantation year and assessed their predictive value for subsequent acute rejection (AR). The trajectories of urinary CXCL10 showed an early increase at 1 month (p = 0.0005) and 3 months (p = 0.0009) in patients who subsequently developed AR. At 1 year, the AR-free allograft survival rates were 90% and 54% in patients with CXCL10:creatinine (CXCL10:Cr) levels <2.79 ng/mmoL and >2.79 ng/mmoL at 1 month, respectively (p < 0.0001), and 88% and 56% in patients with CXCL10:Cr levels <5.32 ng/mmoL and >5.32 ng/mmoL at 3 months (p < 0.0001), respectively. CXCL9:Cr levels also associate, albeit less robustly, with AR-free allograft survival. Early CXCL10:Cr levels predicted clinical and subclinical rejection and both T cell- and antibody-mediated rejection. In 222 stable patients, CXCL10:Cr at 3 months predicted AR independent of concomitant protocol biopsy results (p = 0.009). Although its positive predictive value was low, a high negative predictive value suggests that early CXCL10:Cr might predict immunological quiescence on a triple-drug calcineurin inhibitor-based immunosuppressive regimen in the first posttransplantation year, even in clinically and histologically stable patients. The clinical utility of this test will need to be addressed by dedicated prospective clinical trials.

Measurement of skin thickness and skin elasticity to evaluate the effectiveness of intensive decongestive treatment in patients with lymphoedema: a prospective study.

BACKGROUND: Complex decongestive physiotherapy (CDP) is used to treat patients with severe lymphoedema. The efficacy of CDP is usually quantified by calculating limb volume from repeated measurements of circumference at least 10 points before and after treatment of an affected limb. Measurement is time-consuming and operator-dependent. OBJECTIVES: To determine whether decreased dermal thickness is correlated with decreased volume after intensive CDP. METHODS: A consecutive series of patients admitted for intensive CDP were studied over a 6-month period. Before and after CDP, we measured circumference, dermal thickness elasticity and finally improvement in quality of life using a visual analogue scale (VAS). RESULTS: Thirty patients were included in the study. Only three patients were previously untreated. The average relative reduction in limb volume was 4% and the reduction in the dermal thickness was 15% (correlation: r = 0.37, P = 0.05). Viscoelasticity was decreased by 13%. VAS quality of life score was improved by 30%. CONCLUSION: Changes in dermal thickness are slightly correlated with volume changes before and after 5-day intensive CDP in a selected series of patients previously treated at home.

Serial lymphoscintigraphic findings in a patient with Gorham's disease with lymphedema.

Gorham's disease is a rare disorder characterized by vascular, "lymphangio- matous" and/or "hemangiomatous" lesions in bone and surrounding soft tissues. Associated lymphedema has not been reported and clinical evolution is unpredictable. Plain radiographs, CT, MRI, and occasionally bone scintigraphy, are used to detect the bone and soft tissues changes. Biopsy is a major component of the diagnostic process. We report the findings of serial lymphoscintigraphy in a young boy with a polyostotic Gorham's disease associated with lymphangioma of the thigh and lower limb lymphedema. In this patient, lymphoscintigraphy was useful for diagnosis and follow-up of primary lymphedema. It provided valuable information concerning the occurrence, location, and progression of lymphatic lesions in both bone and soft tissues.

[Frequency of lymphoscintigraphic anomalies in the contralateral limb and progression of unilateral primary lymphedema in children]. / Fréquence des anomalies lymphoscintigraphiques infracliniques controlatérales et évolution des lymphœdèmes primaires unilatéraux de l'enfant.

BACKGROUND: Primary lymphoedema (LE) is the consequence of lymphatic insufficiency, usually associated with hypoplasia of the lymph vessels and/or nodes. Lymphoscintigraphy allows early diagnosis. OBJECTIVES: To assess the frequency of contralateral LE by lymphoscintigraphy in children with unilateral primary LE of one limb; to assess facets of clinical bilateralization of LE. METHODS: This retrospective single-centre study included children with unilateral LE followed up at the Tours university hospital centre between 2004 and 2014. Parents were contacted by phone to obtain follow-up data. RESULTS: Of the 13 children included, 6 (46%) displayed bilateral lymphatic anomalies on lymphoscintigraphy. Within a median follow-up period of 6 years, clinical bilateralization was observed in one girl after progression of her LE for 7 years; in her case, bilateral lymphatic insufficiency was detected at the initial lymphoscintigraphy. CONCLUSION: While contralateral subclinical lymphatic insufficiency is frequent in children with unilateral primary LE of the limbs, clinical bilateralization appears only rarely.

Consideration of hereditary effects in the radiological protection system: evolution and current status.

PURPOSE: The purpose of this paper is to provide an overview of the methodology used to estimate radiation genetic risks and quantify the risk of hereditary effects as outlined in the ICRP Publication 103. It aims to highlight the historical background and development of the doubling dose method for estimating radiation-related genetic risks and its continued use in radiological protection frameworks. RESULTS: This article emphasizes the complexity associated with quantifying the risk of hereditary effects caused by radiation exposure and highlights the need for further clarification and explanation of the calculation method. As scientific knowledge in radiation sciences and human genetics continues to advance in relation to a number of factors including stability of disease frequency, selection pressures, and epigenetic changes, the characterization and quantification of genetic effects still remains a major issue for the radiological protection system of the International Commission on Radiological Protection. CONCLUSION: Further research and advancements in this field are crucial for enhancing our understanding and addressing the complexities involved in assessing and managing the risks associated with hereditary effects of radiation.

Contributions of SPECT/CT imaging to the lymphoscintigraphic investigations of the lower limb lymphedema.

Lymphoscintigraphy is a safe and reliable technique for investigating lymphedema. However, interpretation of delayed planar conventional imaging may be questionable due to the superimposition of soft tissues. Therefore, the aim of this retrospective study was to evaluate the contribution of single photon emission computed tomography/computed tomography (SPECT/CT) to lymphoscintigraphic investigation in a selected population with abnormal interstitial activity. Forty one patients with lower limb lymphedema either primary (n=17) or secondary (n=5), or associated with chronic venous insufficiency (n=19) underwent lymphoscintigraphy according to a standard protocol. SPECT/CT imaging that started immediately after planar imaging covered the part of the lower limbs with the most significant interstitial activity. The CT images were also analyzed separately to identify the typical honeycomb pattern of lymphedema. SPECT/CT identified additional abnormalities in vessels and soft tissues in 19 patients (46%). The additional information, primarily related to dermal collateralization of flow, dermal backflow, lymphangioma, and lymphorrhea, aided in understanding the physiopathology of edema and may have influenced management in 35 patients (85%). The honeycomb appearance of the soft tissues was noted on CT in most patients (90%). This study suggests that SPECT/CT is a promising addition to planar imaging in lymphoscintigraphic investigations of lymphedema.

[Persistent aphthous mouth ulcers associated with tocilizumab: two cases]. / Ulcérations buccales aphtoïdes persistantes associées au tocilizumab: deux cas.

BACKGROUND: Tocilizumab, a humanized monoclonal antibody that blocks interleukin-6 receptor, is approved for use in rheumatological diseases. The most frequent adverse events reported are infections. We describe for the first time the occurrence of recurrent aphthous mouth ulcers in two patients on TCZ. PATIENTS AND METHODS: Two patients were treated with TCZ for rheumatological disease. A few weeks after administration of TCZ, they presented with multiple painful mouth ulcers that would not heal until TCZ had been withdrawn. In both cases, the oral ulcers resolved 6 to 7weeks after withdrawal of TCZ and readministration of the drug led to recurrence of oral ulcers within 10days in both patients. DISCUSSION: We describe for the first time the occurrence of aphthous mouth ulcers induced by TCZ. The causative role of TCZ was established by positive rechallenge. These cases were similar to a recently reported case of multiple intestinal aphthous ulcers occurring during TCZ treatment. Such mucosal side effects may be explained by similar inflammatory mechanisms but appear paradoxical because TCZ inhibits a pro-inflammatory cytokine, interleukin 6. TCZ treatment can be maintained if necessary, in combination with colchicine, as reported for one of our patients.

[D-penicillamine-induced pemphigus: changes in anti-32-2B immunostaining patterns]. / Autonomisation d'un pemphigus induit par la D-pénicillamine: évolution de l'immunomarquage par l'anticorps anti-32-2B.

BACKGROUND: It has been reported that D-penicillamine causes pemphigus that is typically superficial. Immunostaining with monoclonal anti-32-2B antibody targeting desmoglein 1 and 3 can help differentiate between drug-induced and classical auto-immune pemphigus. Absence of specific staining militates in favour of drug-induced pemphigus whilst positive staining suggests an auto-immune aetiology that is ongoing despite discontinuation of drug therapy. PATIENTS AND METHODS: A 59-year-old male patient was referred for management of superficial pemphigus 1 year after starting D-penicillamine treatment for scleroderma. The diagnosis of pemphigus was confirmed histologically (intra-epidermal cleavage, acantholysis and perikeratinocytes, deposition of IgG and complement C3). Immunochemical staining with anti-32-2B antibody was initially normal, in keeping with drug-induced pemphigus. Despite discontinuation of D-penicillamine, pemphigus recurred in 2008. A further skin biopsy was undertaken and anti-32-2B staining was abnormal, which is consistent with auto-immune pemphigus. DISCUSSION: Numerous cases of drug-induced pemphigus have been described in the literature. In approximately half of all cases, the pemphigus recedes after cessation of the causative drug. However, there have been no previous reports that changes over time in the immunostaining with anti-32-2B antibodies can mirror a change in form of pemphigus from a drug-induced type to an idiopathic type as well as the associated clinical feature of persistence after drug withdrawal. CONCLUSION: Normal staining with anti-32-2B antibody is associated with a favourable prognosis as regards resolution of drug-induced pemphigus. When, as in this case, status changes to abnormal staining, there is a risk that the pemphigus may become chronic despite discontinuation of therapy.

Changes in the nail unit in patients with secondary lymphoedema identified using clinical, dermoscopic and ultrasound examination.

BACKGROUND: Secondary lymphoedema is characterized by lymphatic stasis that is often the result of a lymph node lesion. At advanced stages it may cause trophic changes in the skin. However, the presence of changes in the nail unit has not been reported to date. OBJECTIVES: The aim of this study was to determine the presence of nail abnormalities in cases of secondary lymphoedema. METHODS: This was a prospective study, conducted on patients with unilateral secondary lymphoedema. A comparative clinical and dermoscopic examination and 20-MHz high-resolution ultrasound imaging of the affected limb and the contralateral limb were performed. RESULTS: Thirty-three patients were included. On physical examination, hyperkeratosis of the lateral nail folds, friability of the nail surface, 'ragged' proximal nail folds and cuticle and apparent leuconychia were observed more frequently on the lymphoedematous limb. The ultrasound study of the nails of the thumb and the big toe did not reveal any differences in thickness of the different structures of the nail between the lymphoedema side and the opposite side. The nail matrix was longer on the lymphoedema side. CONCLUSIONS: Our study showed mild changes in the nail unit compatible with the xerosis often associated with severe lymphoedema. However, the study also showed frequent evidence of 'ragged' cuticles, which in these patients at high risk of erysipelas are entry points for bacteria. This should be taken into account when counselling patients with limb lymphoedema in order to prevent erysipelas.

[HIV prevention with PrEP: Challenges and prospects]. / Prévenir le VIH par la PrEP : enjeux et perspectives.

Pre-exposure prophlaxis (PrEP) is the use of antiretroviral drugs by uninfected people to prevent human immunodeficiency virus (HIV) infection. PrEP is used by people who are at substantial risk of being exposed to HIV. Numerous clinical trials have confirmed its effectiveness in reducing HIV acquisition and PrEP has been approved and allowed in several countries including France. However, PrEP uptake remains low as concerns about increase in sexual risk behaviour with PrEP use in the wake of a growing epidemic of sexually transmitted infections, and fear of drug resistance have been expressed. As a result, the difference between the proportion of people on PrEP and the proportion of people who would be very likely to use PrEP if they could access it -otherwise known as the PrEP gap- remains high. Nowadays, studies continue to explore long-term effects of PrEP as well as expand the array of available technologies and regimens.

High-resolution ultrasonography assists the differential diagnosis of blue naevi and cutaneous metastases of melanoma.

BACKGROUND: Metastases of cutaneous melanoma may simulate benign blue naevi clinically. OBJECTIVES: To investigate the value of ultrasonography in the differential diagnosis of lesions that look similar clinically, i.e. blue naevi and cutaneous metastases of melanoma. METHODS: Participants were invited for inclusion in the study if they had a cutaneous blue lesion clinically suggestive of a blue naevus or cutaneous metastasis of melanoma. After obtaining signed consent, the lesion was photographed and studied using dermoscopy and high-resolution ultrasonography before being removed for histological examination. Clinical, dermoscopic and ultrasonographic images were reviewed anonymously by four dermatologists to assign the diagnosis of blue naevus or metastasis of melanoma. The diagnostic performance of clinical examination, dermoscopy and sonography was assessed for the ability of each to differentiate between metastases of melanoma and blue naevi with reference to the histological diagnosis. Moreover, experts undertook a semeiological description of each ultrasonographic image according to seven items: location of the lesion, echogenicity, homogeneity, shape of the lesion, definition of margins, posterior acoustic shadow and increased posterior echogenicity. RESULTS: Twenty-eight patients were included with a total of 39 blue skin lesions, and 17 of the 28 patients had a previous history of melanoma. Interobserver agreement in the semeiological description of the sonographic images was good (κ≥0·6) for five of seven items. Sonography was more specific (94%) than clinical examination (77%) and dermoscopy (74%). The sonographic features contributing to the differential diagnosis were: location of the lesion (P=0·027), shape of the lesion (P<0·001), homogeneity (P=0·001) and increased posterior echogenicity (P=0·007). CONCLUSIONS: Ultrasonography is a reproducible and specific tool that can assist the differential diagnosis between blue naevi and metastases of melanoma. A blue naevus is a homogeneous, hypoechoic, 'dish-shaped' lesion, located in the superficial dermis, whereas metastases of melanoma are 'potato-shaped', hypoechoic, heterogeneous lesions, located in the hypodermis.

High-resolution cutaneous ultrasonography to differentiate lipoedema from lymphoedema.

BACKGROUND: Lipoedema is an accumulation of fat abnormally distributed in the lower limbs, and lymphoedema is oedema caused by a deficiency of the lymphatic system. High-resolution ultrasound operating at 20 MHz makes it possible to characterize dermal oedema. OBJECTIVES: The purpose of our study was to demonstrate that high-resolution ultrasound imaging of the skin can differentiate lipoedema from lymphoedema. METHODS: Sixteen patients with lymphoedema (22 legs), eight patients with lipoedema (16 legs) and eight controls (16 legs) were included. Patients with lipolymphoedema were excluded. Ultrasound examinations were carried out with a real-time high-resolution ultrasound device on three different sites for each lower limb. The images were then anonymized and examined by an independent dermatologist who was blind to the clinical diagnosis. A new series of images was examined by three dermatologists to check interobserver agreement. RESULTS: A significant difference in dermal thickness was observed between patients with lymphoedema and those with lipoedema and between patients with lymphoedema and controls. No significant difference in dermal thickness was shown between patients with lipoedema and controls at the thigh or ankle. Dermal hypo-echogenicity was found in at least one of the three sites in 100% of patients with lymphoedema, 12.5% of cases with lipoedema and 6.25% of the controls. Hypoechogenicity affected the entire dermis in all cases of lymphoedema except one. In cases of lipoedema and controls, hypoechogenicity was localized at the ankle and prevailed in the upper dermis. The expert correctly diagnosed all lower limbs with lymphoedema. No cases of lipoedema were diagnosed as lymphoedema. Exact interobserver agreement was excellent (0.98). CONCLUSIONS: High-resolution cutaneous ultrasonography makes it possible to differentiate lymphoedema from lipoedema. Obtaining a reliable diagnosis through high-resolution cutaneous ultrasonography might be valuable for improving the treatment of lipoedema and lymphoedema.

A new scalp formulation of calcipotriol plus betamethasone dipropionate compared with each of its active ingredients in the same vehicle for the treatment of scalp psoriasis: a randomized, double-blind, controlled trial.

BACKGROUND: There is a need for new treatments for scalp psoriasis, as many topical treatments are cosmetically unacceptable and difficult to apply, resulting in poor compliance. OBJECTIVES: To compare the efficacy and safety of a new, once-daily, two-compound scalp formulation (Xamiol; LEO Pharma A/S, Ballerup, Denmark) containing calcipotriol 50 microg g(-1) plus betamethasone 0.5 mg g(-1) (as dipropionate), with the active ingredients as single compounds in the same vehicle. METHODS: This 8-week, multicentre, double-blind, parallel-group study, randomized adult patients with scalp psoriasis involving > 10% of the scalp to the two-compound scalp formulation (n = 568), betamethasone dipropionate 0.5 mg g(-1) (n = 563), or calcipotriol 50 microg g(-1) (n = 286). The primary efficacy measure was the proportion of patients with 'absence of disease' or 'very mild disease' according to investigators' assessments at week 8. RESULTS: The proportion of patients with 'absence of disease' or 'very mild disease' at week 8 was significantly higher in the two-compound group (68.4%) than the betamethasone dipropionate (61.0%, P = 0.0079) or calcipotriol (43.4%, P < 0.0001) groups. The proportion of patients rating their scalp psoriasis as 'clear' or 'almost clear' was significantly higher for the two-compound scalp formulation (69.6%) than for betamethasone dipropionate (59.9%, P = 0.0006) or calcipotriol (44.7%, P < 0.0001). The incidence of lesional/perilesional adverse events was lower in the two-compound and betamethasone dipropionate groups than the calcipotriol group. CONCLUSIONS: The two-compound scalp formulation was well tolerated and more effective in the treatment of scalp psoriasis than either of its individual components in the same vehicle.

Contribution of skin biometrology to the diagnosis of the Ehlers-Danlos syndrome in a prospective series of 41 patients.

BACKGROUND/PURPOSE: The diagnosis of the Ehlers-Danlos syndrome (EDS) is primarily clinical. Clinical signs result from modifications of the rheological properties of the skin: thickness, extensibility and hydration. Our main objective was to demonstrate what skin biometry can contribute to the diagnosis and evaluation of the different types of EDS. METHODS: Forty-one patients clinically diagnosed with EDS were paired by age and sex to 41 healthy subjects with no known dermatologic disease, in particular connective tissue diseases. We measured skin thickness, extensibility, hydration and sebum secretion by skin ultrasonography, use of a Cutometer, a Corneometer and a Sebumeter. RESULTS: The skin is thinner in all three disease types (classical, hypermobility and vascular). It is more extensible only in the classical type, and more hydrated and fatty in the hypermobility type. CONCLUSION: Non-invasive measurement of skin thickness and elasticity are quantitative parameters that can be used to better diagnose EDS. Moreover, the sebaceous rate can help to diagnose the hypermobility type whereas the immediate retraction distinguishes the classical form from vascular and hypermobile types.

Epidemiology of fatal cases associated with pandemic H1N1 influenza 2009.

This article describes the characteristics of 574 deaths associated with pandemic H1N1 influenza up to 16 July 2009. Data (except from Canada and Australia) suggest that the elderly may to some extent be protected from infection. There was underlying disease in at least half of the fatal cases. Two risk factors seem of particular importance: pregnancy and metabolic condition (including obesity which has not been considered as risk factor in previous pandemics or seasonal influenza).
