Delayed eczematous skin reaction as an adverse drug reaction to immunoglobulin infusions: A case series.

BACKGROUND: Pompholyx and eczematous reactions are known adverse reactions to intravenous immunoglobulins (IVIg) infusion, but little is known about their clinical characteristics, associated outcomes and management. OBJECTIVE: To describe IVIg-induced eczematous skin reactions. METHODS: We conducted a retrospective study on cases of delayed skin reactions post-IVIg infusion notified to the French Regional Pharmacovigilance Centre from 1985 to 2020. RESULTS: A total of 27 patients were identified, of whom 85% were male. IVIg infusions were given in a neurological indication in 82% of cases. Eczematous skin reactions occurred in two-thirds of cases after the first infusion, with a median time to onset of 11 days. Palmoplantar pompholyx was the most common presentation, being seen in 63% of patients. Other eruptions were erythemato-squamous or maculopapular. Eight patients were classified as severely affected and developed extensive lesions (>50% BSA). One third of the 27 patients required hospitalization. All of the severe eczematous reactions involved males receiving high doses of IVIg for neurological diseases. Biopsies of severe cases revealed a common non-specific eczematous pattern. Relapses were frequent and more severe than the initial reaction. Reintroduction of the same IVIg product consistently resulted in relapse, whereas switching IVIg type produced relapse in only 53% of patients. CONCLUSION: We present the largest retrospective study of delayed skin reactions after IVIg infusions. This side-effect may be severe and have a polymorphic presentation. Relapse occurs frequently but less consistently after IVIg switch.

Immediate fine-tuning of DIEP flaps using the Wise pattern mastectomy: Description of the technique and a retrospective analysis of complication rates.

INTRODUCTION: Elliptical skin-sparing mastectomy in patients with large or ptotic breasts usually leaves loose mastectomy skin flaps, which need to be either resected or gathered over the DIEP flap. This results in poor control of the breast footprint and under-projected DIEP flaps in a loose mastectomy skin pocket, that tend to slip laterally towards the axilla. We believe that the use of a Wise pattern mastectomy will allow for immediate treatment of these concerns. MATERIALS AND METHODS: A retrospective, uncontrolled analysis of a prospectively-maintained database of patients operated by the five surgeons performing breast reconstructions at the University of Montreal Hospital Centre. Study population was patients with a BMI of over 25 and grade II/III breast ptosis who underwent a Wise pattern mastectomy with immediate DIEP flap reconstruction. Analysis was performed of the complication rates of the technique in the first six months after the surgery. RESULTS: Out of a total of 53 breasts in 44 patients reconstructed with a DIEP flap immediately post Wise pattern mastectomy, we report nine cases of partial mastectomy-flap necrosis not needing revision, five cases of significant mastectomy flap necrosis needing debridement and skin grafting, and two cases of inability to adequately close the Wise pattern intraoperatively after DIEP placement, necessitating retention of DIEP skin in the inferior pole. None of the mastectomy flap complications occurred in irradiated breasts. CONCLUSION: In patients with large or ptotic breasts, the Wise pattern mastectomy before an immediate DIEP reconstruction allows for immediate shaping of the breast by controlling the breast pocket, footprint, and excess skin.

Childhood epidermal necrolysis and erythema multiforme major: a multicentre French cohort study of 62 patients.

INTRODUCTION: The distinction between epidermal necrolysis [EN; including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and overlap syndrome] and erythema multiforme major (EMM) in children is confusing. We aimed to better describe and compare these entities. MATERIALS AND METHODS: This French retrospective multicentre study included children ≤18 years old referred for EN or EMM between 1 January 2008 and 1 March 2019. According to pictures, children were reclassified into TEN/overlap, SJS or EMM/unclassified (SJS/EMM) groups and compared for epidemiological and clinical data, triggers, histology and follow-up. RESULTS: We included 62 children [43 boys, median age 10 years (range 3-18)]: 16 with TEN/overlap, 11 SJS and 35 EMM. The main aetiologies were drugs in EN and infections (especially Mycoplasma pneumoniae) in EMM (P < 0.001), but 35% of cases remained idiopathic (TEN/overlap, 47%; SJS, 24%; EMM, 34%). The typical target lesions predominated in EMM (P < 0.001), the trunk was more often affected in EN (P < 0.001), and the body surface area involved was more extensive in EN (P < 0.001). Mucosal involvement did not differ between the groups. Two patients with idiopathic TEN died. Histology of EMM and EN showed similar features. The recurrence rate was 42% with EMM, 7% with TEN/overlap and 0 with SJS (P < 0.001). Sequelae occurred in 75% of EN but involved 55% of EMM. CONCLUSION: Clinical features of EN and EMM appeared well demarcated, with few overlapping cases. Idiopathic forms were frequent, especially for EN, meaning that a wide and thorough infectious screening, repeated if needed, is indicated for all paediatric cases of EN/EMM without any trigger drug. We propose a comprehensive panel of investigations which could be a standard work-up in such situation. Sequelae affected both EN and EMM.

Immediate breast reconstruction surgery with expander/direct implant and use of acellular dermal matrix: Does hormone therapy increases the risk of infection?

BACKGROUND: The use of hormone therapy (tamoxifen and aromatase inhibitors) has been shown to increase venous thromboembolism. However, while estrogens play a crucial role in wound healing, no study has assessed the impact of tamoxifen or aromatase inhibitors on other postoperative breast reconstruction complications, including infections, necrosis, capsular contracture and seroma. As breast cancer patients undergoing Implants-ADMs breast reconstruction are often receiving hormone therapy, it is unclear whether this increased infection risk is associated with increased infections cases. METHODS: A prospective study was performed on patients undergoing breast reconstruction at an academic institution from 2013 to 2016. Patients were divided by use of hormone therapy at the time of surgery. Complication rates, including infections, necrosis, seroma and hematomas, were compared and analyzed using univariate and logistic regression models. RESULTS: Among a total of 112 patients (183breasts), 58 patients (91 breasts) were receiving hormone therapy and 54 patients (92 breasts) were not. The hormone therapy group had a higher incidence of postoperative mastectomy skin infection (20.7% versus 7.4%; P=0.0447), we didn't find any significant differences in necrosis. CONCLUSIONS: Hormone therapy was associated with a higher incidence of Infections after breast reconstruction with ADMs and implants. The authors propose an individualized approach to the preoperative cessation of tamoxifen or aromatase inhibitors. Immediate breast reconstruction surgery with expander/direct implant and use of acellular dermal matrix: does hormone therapy increases the risk of infection?

TOXICAN: a guide for grading dermatological adverse events of cancer treatments.

PURPOSE: The dermatological toxicity of cancer treatments is frequent and sometimes debilitating. Its reference classification, the NCI-CTCAE (National Cancer Institute-Common Terminology Criteria for Adverse Events), is sometimes difficult to use and does not include yet the newest toxicities. Our objective was to create a guide, TOXICAN, based on the CTCAE, which is easy to use in everyday practice and which facilitates the recognition and grading of these dermatological toxicities. METHODS: This guide was developed by a working group ("GESTIM") comprising oncodermatologists, allergists, pathologists, and researchers from Nantes University Hospital. It was based on the dermatological toxicities found in the CTCAE and adapted to daily practice. These toxicities were grouped into categories and associated with photographs of typical cases to aid recognition. A simplified grading scale derived from the CTCAE was also created. This booklet was validated by means of user evaluation, and then the Delphi consensus method. RESULTS: We selected 32 dermatological toxicities, including 12 created by our group, sorted into 7 categories: skin rash, dry skin/pruritus, hyperkeratotic papules, palmoplantar changes, hair and nail changes, mucosal changes, and others. Our simplified grading scale only differed from the CTCAE for one item, urticaria. Three items were modified after evaluation by the user group and 11 after application of the Delphi method. CONCLUSION: The objective of our practical guide is to facilitate the use of the CTCAE for recognizing and grading dermatological toxicity of cancer treatments in order to provide optimal guidance for therapeutic adaptations. Its impact on clinical practice remains to be evaluated.

A retrospective comparison study of the infra-mammary approach to the standard mastectomy scar in the 2nd stage of tissue expander to implant breast reconstruction.

BACKGROUND: Staged expander-to-implant breast reconstruction is plagued by a high prevalence of complications. We have employed an alternative approach of using the infra-mammary crease (IMF) for expander-to-implant exchange. The IMF approach was thought to utilize healthier tissues, which are believed to be less affected by the process of tissue expansion, and reside distant from the field of the radiotherapy boost. METHODS: A retrospective chart review was performed on all patients undergoing a staged implant-based breast reconstruction from 2009 to 2014. Patients were divided into those that received an IMF vs. a mastectomy scar (MS) approach in the second stage of expander-to-implant exchange. Patient characteristics and postoperative complications were extracted. RESULTS: A total of 75 patients undergoing 96-staged reconstructions were included (70 cases MS vs. 26 cases IMF). Patient demographics and implant characteristics were similar between groups. There were no significant differences in overall complications between the groups (11.4% MS vs. 7.7% IMF, P=0.72). All cases of implant exposure occurred in the MS group and had a history of radiation. However, there was no statistical difference in implant exposure between groups (4.3% MS vs. 0% IMF, P=0.56) or in the irradiated patients subgroup (20% MS vs. 0% IMF, P=0.25). CONCLUSIONS: In conclusion, the IMF approach for the second stage of expander-to-implant exchange is an alternative technique with a similar prevalence of complications as the traditional mastectomy scar approach. This technique may prove useful in reducing postoperative incisional dehiscence and implant exposure, especially in the context of radiotherapy.

[CONDYDAV: A multicentre observational study of patients presenting external genital warts in France]. / CONDYDAV : étude observationnelle multicentrique des patients présentant des condylomes dans les dispensaires antivénériens en France.

BACKGROUND: Since 2007 in France, human papilloma virus (HPV) vaccination has been licensed for use as a vaccine against HPV 6, 11, 16 and 18. The impact on the epidemiology of external genital warts (EGWs) in a large population remains unclear. OBJECTIVES: To determine epidemiologic and clinical features of patients presenting EGWs in France in the era of HPV vaccination. PATIENTS AND METHODS: In this prospective, observational study, we analyzed clinical features and treatments between January 1st, 2012 and March 31, 2012 for patients consulting for EGWs at 15 STI clinics throughout France. RESULTS: A total of 372 men and 111 women were included; mean age 31.2 years. The women were younger than the men (31.7 and 28.9 years respectively P<0.05). Among the patients, 416 (85.7%) were heterosexual, 13 bisexual and 54 (11.2%) homosexual, including one female. Males reported more sexual partners in the last 12 months (more than 3 partners in 32.6% versus 11.9%, P<0.01). Among the men, 230 had involvement of the penis alone and 46 had involvement of the anus alone. Seventy-six patients had EGWs of the anus, and of these 26 were MSM. In females, 76 had an infection of the vulva alone and 22 co-infection of the vulva and anus. MSM and females were at higher risk than heterosexual males for anal involvement (P<0.0001 and P=0.004, respectively). Three women had been vaccinated: two with Gardasil® and one with Cervarix®. Cryotherapy was the preferred treatment. CONCLUSION: With the advent of HPV vaccination, a global strategy for the prevention and treatment of EGW should be implemented.

[Skin tests in chronic hand dermatitis]. / Place des tests allergologiques dans l'eczéma chronique des mains.

Chronic hand dermatitis is often multifactorial but allergic causes are frequent and can complicate atopic dermatitis or irritant dermatitis. The management of patients affected by hand dermatitis includes detailed interrogation and a complete examination of the skin. Allergologic tests must be systematically realized if examination is suggestive of contact dermatitis or protein contact dermatitis, if an occupational origin is suspected but also in all patients in which treatment is ineffective. Skin tests include patch tests with the European standard series, specialized or additional series if necessary. Skin tests may also include personal items used by patients on a daily basis. If protein contact dermatitis is suspected skin tests include prick tests. Only complete and definitive eviction of allergens can allow a complete and definitive cure of chronic hand dermatitis.

[Therapeutic patient education in chronic hand dermatitis]. / Éducation thérapeutique du patient dans l'eczéma chronique des mains.

Hand dermatitis (HD) is usually due to a combination of various interacting factors. It involves significant impairment of the quality of life with psychological and socioeconomic impact. A therapeutic education program in HD.was elaborated by 19 health professionals (dermatologists, occupational clinical physicians, nurses, psychologists, environmental medical advisor) with experience in therapeutic education or skills in HD, according to the recommendations of Haute Autorité de Santé. The program includes an individual medical consultation to perform educational diagnostic, two collective workshops and a medical evaluation consult. Two group workshops "the disease, irritant factors and its treatments" and "the experiences and feelings" were elaborated with learning objectives and educative tools. Different scores were proposed to evaluate the program and acquired skills. Therapeutic education is an efficient way to help patients to adopt skin protection measures essential to healing. We propose a guideline of therapeutic education in HD including skills and educative tools and intended for health professionals to serve as working basis.

[A surgical follow-up platform to reduce complications in free flap surgery]. / Une plateforme de suivi chirurgical pour réduire les complications en reconstruction par lambeau libre.

STUDY OBJECTIVE: In 2007, the WHO adopted surgical safety as the theme for the 2nd global patient safety challenge. Measurement of surgical services was identified as a surgical care area in need of major improvements. Aware of this recommendation, a preliminary study was conducted in our hospital and showed that the incidence of complete necrosis in free flap surgery was 10.0 %, a rate among the highest found in medical literature. In that context, an interactive surgical follow-up platform (PICS) was implemented to monitor outcomes in free flap surgery. The hypothesis was to reduce the short-term failure of microsurgical reconstructions. PATIENTS AND METHODS: In Summer 2010, the tool for capturing and analyzing data (PICS) was implemented. All patients who underwent free flap reconstruction were prospectively registered in the platform. The primary endpoints to evaluate the effectiveness of the tool are the rates of surgical re-exploration and complete necrosis of the flap. RESULTS: From May 2010 to December 2011, 129 cases of free flap reconstruction were recorded. The rate of total flap necrosis was 10.0 % before database introduction and declined to 3.1 % afterwards (P<0.05). Take-backs occurred in 27.0 % of free flap reconstructions at baseline and in 10.1 % after implementation (P<0.01). CONCLUSION: The implementation of PICS is associated with a significant improvement of postoperative short-term outcomes in free flap surgery. This tool is effective to evaluate care services and provides an increased surgical safety for patients. Surgical teams are encouraged to implement a data collection tool in order evaluate operative care on a routine basis.

[Guide for therapeutic education program in psoriasis]. / Élaboration d'un référentiel d'éducation thérapeutique dans le psoriasis.

INTRODUCTION: Psoriasis is a chronic inflammatory skin disease which can cause significant impairment of quality of life, absenteeism at work and significant psychological distress. This justifies the elaboration of a multidisciplinary education program for patients. The objective of this work was to develop the content of a therapeutic education program in psoriasis, which may serve as a basis for teams wishing to develop psoriasis therapeutic education in their community. PATIENTS AND METHODS: A group of 15 health professionals (dermatologists, dermatology nurses, and psychologist) and four psoriasis patients representatives of the psoriasis patient association (Association pour la lutte contre le psoriasis) participated in the development of this program. Health professionals all had an experience in therapeutic patient education in psoriasis through prior participation in a multicenter open pilot study, evaluating a therapeutic education program in psoriasis. Based on the previous experience, preparatory work in subteams was initiated to prepare draft objectives and content of the program. A two-day meeting was then organized to discuss in depth content of the therapeutic education program and elaborate recommendations. The meeting structure combined subteam work and plenary sessions. The following program was elaborated: two individual sessions and three group sessions. The groups have worked for two days, according to a predefined pattern: interview guide of educational diagnostic, content of collective workshops and knowledge questionnaire. All these documents were validated in plenary session. The methodology used for the development of this program followed the recommendations of the HAS in the field of chronic disease. RESULTS: In the end, were retained three collective workshops, preceded by a consultation of individual educational diagnosis and knowledge questionnaire followed by an evaluation session at the end of the program. The interview guide for educational diagnosis and the knowledge basis questionnaire have been defined. Three themes of group workshops were defined: (1) understanding the disease, (2) understanding the mechanism of onset of disease and treatments available, (3) how to live with psoriasis in everyday life. For each workshop, were defined learning objectives, skills to acquire and how to get there. DISCUSSION: We describe here a framework of educational therapy program in psoriasis comprising educational objectives, skills to acquire, basic disease knowledge, suitable for patients with psoriasis. The content was tailored to patient language and knowledge based on feedback from participating patients. The list of skills may be adapted to patient's individual needs. This program serves primarily as a working basis for the caregiver, to standardize practices in terms of therapeutic education in psoriasis in France.
