Lesiones cutáneas relacionadas con la dependencia en el paciente crítico pronado. Estudio de incidencia / Dependency-related skin lesions in the prone critical patient. Incidence study

Objetivo: Determinar la incidencia de las lesiones cutáneas relacionadas con la dependencia (LCRD) en los pacientes en decúbito prono (DP) e identificar los factores predisponentes. Método: Estudio descriptivo-longitudinal en 2 unidades de cuidados intensivos (UCI) polivalentes. Se incluyeron pacientes con ventilación mecánica invasiva y DP, sin lesiones al ingreso. Se registraron 3 tipos de LCRD: (lesiones por presión [LPP], lesiones cutáneas asociadas a la humedad [LESCAH] y lesiones por fricción [LF]), variables demográficas, diagnóstico, estancia, episodios en DP, cambios posturales, APACHE II (Acute Physiology and Chronic Health Disease Classification System), prealbúmina al ingreso, índice de masa corporal (IMC), diabetes, hipertensión arterial, tabaquismo, enfermedad vascular periférica (EVP), fármacos vasoactivos, escala de Braden y mortalidad. Análisis bivariante: prueba de χ2, t-Student o U de Mann-Whitney. Multivariante: regresión logística. Resultados: Se incluyeron 49 pacientes. Se realizaron 170 DP. Aparecieron 41 LCRD en 22 pacientes con una incidencia acumulada del 44,9% (IC 95%: 31,6-58,7). El 63,4% LPP (73,1% faciales; 76,9% categoría II), el 12,2% LESCAH (60% inguinales; 60% categoría II) y el 24,4% LF (50% torácicas; 70% categoría III). La mediana de edad del grupo con lesiones (GCL) fue de 66,5 (61,8-71,3) frente al 64 (43-71) años del grupo sin lesiones (GSL); p=0,04. El 80% del GCL tenía EVP frente al 20% del GSL; p=0,03. La mediana de horas totales en DP del GCL fue de 96,9 (56,1-149,4) frente a 38,2 (18,8-57) del GSL; p<0,001. El análisis multivariante seleccionó horas totales DP (OR: 1,03; IC 95%: 1,01-1,05) y la EVP (OR: 8,9; IC 95%: 1,3-58,9) como factores predisponentes para desarrollar LCRD. Conclusiones: Existe una elevada incidencia de LCRD en DP, mayoritariamente lesiones por presión, aunque de baja severidad. Las horas acumuladas en DP y la enfermedad vascular periférica favorecen su desarrollo.(AU)

Objective: To determine the incidence of dependence-related skin lesions (DRSL) in patients in prone position (PP) and to identify the predisposing factors. Method: Follow-up study in two polyvalent intensive care units. Patients undergoing invasive mechanical ventilation and PP with no skin lesions on admission were included. We recorded the 3 types of DRSL:(pressure ulcers (PU), moisture-associated skin damage (MASD) and friction injuries (FI)), demographic variables, diagnosis, length of stay, PP episodes, postural changes, APACHE II (Acute Physiology and Chronic Health Disease Classification System), prealbumin level on admission, body mass index (BMI), diabetes, hypertension, smoking, peripheral vascular disease (PVD), vasoactive drugs, Braden scale and mortality. Bivariate analysis: Chi-square test, t-test or Mann-Whitney U test. Multivariate analysis: logistic regression. Results: Forty nine patients were included and 170 PP were performed. Forty-one DRSL appeared in 22 patients with a cumulative incidence of 44.9% (95% CI: 31.6-58.7). PU accounted for 63.4% (73.1% facial; 76.9% stage II), 12.2% were MASD (60% inguinal; 60% stage II) and 24.4% were FI (50% thoracic; 70% stage III). The median age of the lesion group (LG) was 66.5 (61.8-71.3) vs 64 (43-71) years old in the non-lesion group (NLG), P=.04. Eighty percent of the LG had PVD vs 20% of the NLG, p=0.03. The median total hours on PP of the LG was 96.9 (56.1-149.4) vs 38.2 (18.8-57) of the NIG, P<.001. Multivariate analysis selected total PP hours (OR: 1.03; 95% CI: 1.01-1.05) and PVD (OR: 8.9; 95% CI: 1.3-58.9) as predisposing factors for developing DRSL. Conclusions: There is a high incidence of skin lesions related to prone decubitus dependence, mostly pressure lesions, although of low severity. The accumulated hours in probe position and peripheral vascular disease favor their development.(AU)

Self-care treatment for lymphoedema of lymphatic filariasis using integrative medicine.

BACKGROUND: Lymphatic filariasis (LF) is a neglected tropical disease presenting mainly as lymphoedema (elephantiasis). At present, LF is not effectively treated. Integrative medicine (IM) treatment for lymphoedema uses a combination of Indian traditional medicine, Ayurveda, alongside yoga exercises, compression therapy, antibiotics and antifungal treatments, providing a useful combination where resources are limited and different practices are in use. OBJECTIVES: To assess the effectiveness of the IM in the existing clinical practice of lower-limb lymphoedema management and to determine whether the treatment outcomes align with the World Health Organization (WHO) global goal of LF management. METHODS: Institutional data from electronic medical records of all 1698 patients with LF between 2010 and 2019 were retrospectively analysed using pre- and post-treatment comparisons and the National Institute for Health and Care Excellence guidelines for clinical audit. The primary treatment outcomes evaluated were limb volume, bacterial entry points (BEEPs), episodes of cellulitis, and health-related quality of life (HRQoL). Secondary outcomes included the influence of the patient's sex, duration of illness, education and employment status on volume reduction. Multiple regression analysis, t-test, χ2-test, analysis of variance, Mann-Whitney U-test and the Kruskal-Wallis test were used to assess the association between IM and patients' treatment outcomes. RESULTS: Limb volume reduced by 24.5% [95% confidence interval (CI) 22.47-26.61; n = 1660] following an intensive supervised care period (mean 14.84 days, n = 1660). Limb volume further reduced by 1.42% (95% CI 0.76-2.07; n = 1259) at the first follow-up visit (mean 81.45 days), and by 2.3% between the first and second follow-up visits (mean 231.32 days) (95% CI 1.26-3.34; n = 796). BEEPs were reduced upon follow-up; excoriations (78.4%) and intertrigo (26.7%) were reduced at discharge and further improvements was achieved at the follow-up visits. In total, 4% of patients exhibited new BEEPs at the first follow-up [eczema (3.9%), folliculitis (6.5%), excoriations (11.9%) and intertrigo (15.4%); 4 of 7 BEEPs were recorded]. HRQoL, measured using the disease-specific Lymphatic Filariasis Specific Quality of Life Questionnaire, showed an average score of 73.9 on admission, which increased by 17.8 at the first follow-up and 18.6 at the second follow-up. No patients developed new cellulitis episodes at the first follow-up, and only five patients (5.3%) developed new episodes of cellulitis at the second follow-up. CONCLUSIONS: IM for lower-limb lymphoedema successfully reduces limb volume and episodes of cellulitis, and also reduces BEEPs, leading to improved HRQoL. IM aligns with the LF treatment goals of the WHO and is a low-cost, predominantly self-care management protocol. IM has the potential to change care models and improve the lives of patients with lymphoedema.

The diagnosis, management and prevention of intertrigo in adults: a review.

Intertrigo is a common inflammatory skin disorder caused by skin-on-skin friction in skin folds, due to moisture becoming trapped because of poor air circulation. This can occur in any area of the body where two skin surfaces are in close contact with each other. The aim of this scoping review was to systematically map, review and synthesise evidence on intertrigo in adults. We identified a wide range of evidence and performed a narrative integration of this related to the diagnosis, management and prevention of intertrigo. A literature search was conducted within the following databases: Cochrane Library, MEDLINE, CINAHL, PubMed and EMBASE. After reviewing articles for duplicates and relevance, 55 articles were included. The incorporation of intertrigo in the ICD-11 provides a clear definition and should improve the accuracy of estimates. With regards to the diagnosis, prevention and management of intertrigo, the literature demonstrates consensus among health professionals in approach and this forms the basis for the recommendations of this review: identify predisposing factors and educate patient in reducing these; educate patients in skin fold management and adopt structured skin care routine; treat secondary infection with appropriate topical agent; consider using moisture-wicking textiles within skin folds to reduce skin-on-skin friction, wick away moisture and reduce secondary infection. Overall, the quality of evidence on which to determine the strength of any recommendations for practice remains low. There remains the need for well-designed studies to test proposed interventions and build a robust evidence base.

Toe Web Infections, the Microbiome, and Toe Web Psoriasis: A Review.

OBJECTIVE: To present the toe web space as an anatomically, physiologically, and pathologically unique part of the human body; characterize toe web infections and discuss why they occur; and highlight toe web psoriasis as an uncommon condition that providers should consider if toe web intertrigo does not respond to treatment. DATA SOURCE: This review encompassed many years of clinical observation and photographs; medical textbooks; and a literature search of MEDLINE, PubMed, and Google Scholar. STUDY SELECTION: Primary research keywords included intertrigo, toe web intertrigo, toe web infection, tinea pedis, microbiome, skin microbiome, toe web microbiome, ecology, psoriasis, psoriasis microbiome, intertriginous psoriasis, and Wood's lamp. More than 190 journal articles met the search criteria. DATA EXTRACTION: The authors sought data relating to what makes for a healthy toe web space and what makes for disease. They extracted and collated relevant information to compare and contrast among sources. DATA SYNTHESIS: After understanding the normal toe web space and the microorganisms that normally reside there, the authors investigated why infections occur, how they should be treated, what complications may result, and what other diseases occur in the toe web area. CONCLUSIONS: This review of toe web infection illustrates the effect of the microbiome and reports a rare form of psoriasis that is usually misdiagnosed as athlete's foot. The toe web space is a unique part of the human body that can be affected by a variety of both common and unusual conditions.

Skin assessments and interventions for maintaining skin integrity in nursing practice: An umbrella review.

BACKGROUND: Daily skin care routines are fundamental aspects of clinical nursing practice. Providing skin care, including skin cleansing and application of leave-on products have substantial impact on the prevention and treatment of a number of skin conditions. There are hundreds of individual studies about skin risks, classifications, skin conditions, prevention and treatment. OBJECTIVE: To summarise the overall evidence regarding 1) risk factors associated with xerosis cutis, incontinence-associated dermatitis/diaper dermatitis, intertrigo, skin tears, 2) the performance of diagnostic tests and/or classifications addressing the severity and/or signs and symptoms of xerosis cutis, incontinence-associated dermatitis/diaper dermatitis, intertrigo, skin tears, 3) the effects of skin cleansing/care interventions for the maintenance and promotion of skin integrity in all age groups, 4) effects of skin cleansing/care interventions for the prevention of xerosis cutis, incontinence-associated dermatitis/diaper dermatitis, intertrigo, skin tears in all age groups. DESIGN: Umbrella review. DATA SOURCES: A systematic search in MEDLINE and Embase (via OvidSP), Cochrane and Epistemonikos was conducted. Reference lists and experts were consulted for potentially missed reviews. REVIEW METHODS: Two reviewers screened titles/abstracts and full-texts independently. After rating the risk of bias only low to high overall confidence (AMSTAR 2) and low risk of bias (ROBIS) reviews were included. RESULTS: Twelve systematic reviews were included. Due to substantial heterogeneity regarding study designs, methods, and outcomes all authors presented findings in a narrative synthesis. The validity and reliability of the International Skin Tear Advisory Panel classification is supported by moderate quality evidence, and the reliability and criterion validity for Skin Tear Audit Research were rated insufficient. Overall, review results indicate that structured skin care programs are preferable to unstructured skin care with classic soap and water for maintaining skin integrity in general, preventing skin tears, and to prevent and treat xerosis cutis and incontinence-associated dermatitis. All reviews focusing on leave-on products for the prevention and treatment of incontinence-associated dermatitis and diaper dermatitis indicate the effectiveness of barrier films or lipophilic leave-on products in adults, elderly people and paediatric care, but could not establish the superiority of any product. CONCLUSIONS: The majority of systematic reviews in the field of skin care is at high risk of bias and should not be used for evidence-based practice. Overall, evidence indicates, that structured skin care programs containing low-irritating cleansers and application of leave-on products are beneficial to maintain skin integrity and prevent skin damage across a wide range of different skin conditions across the life span.

Prevalence and associations of xerosis cutis, incontinence-associated dermatitis, skin tears, pressure ulcers, and intertrigo in aged nursing home residents: A representative prevalence study.

BACKGROUND: The number of elderly and care-dependent people is increasing, leading to increased risks of adverse skin conditions. Skin care, including prevention and treatment of vulnerable skin, is an essential part of daily nursing practice in long-term residential settings. For many years, the research focus has been on individual skin problems including xerosis cutis, incontinence-associated dermatitis, skin tears, pressure ulcers, and intertrigo, although people may be affected by several at the same time. OBJECTIVES: Aim of the present study was to describe the prevalence and associations of skin conditions relevant to nursing practice in aged nursing home residents. DESIGN: Analysis of baseline data of a cluster-RCT in long-term residential settings. SETTING: The study was conducted in a representative sample of n = 17 nursing homes in the federal state of Berlin, Germany. PARTICIPANTS: Care dependent nursing home residents being 65+ years. METHODS: A random sample of all eligible nursing homes was drawn. Demographic and health characteristics were collected and head-to-toe skin examinations conducted by dermatologists. Prevalence estimates and intracluster correlation coefficients were calculated, and group comparisons conducted. RESULTS: Three hundred fourteen residents with a mean age of 85.4 (SD 7.1) years were included. The majority was affected by xerosis cutis (95.9%, 95% CI 93.6 to 97.8), followed by intertrigo 35.0% (95% CI 30.0 to 40.1), incontinence-associated dermatitis 21.0% (95% CI 15.6 to 26.3), skin tears 10.5% (95% CI 7.3 to 13.8), and pressure ulcers 8.0% (95% CI 5.1 to 10.8). In total, more than half of the nursing home residents were affected by two or more skin conditions at the same time. Several associations between skin conditions and mobility, care dependency, or cognitive impairment were observed. There were no associations between xerosis cutis, incontinence-associated dermatitis, skin tears, pressure ulcers or intertrigo. CONCLUSIONS: The adverse skin and tissue conditions xerosis cutis, incontinence-associated dermatitis, skin tears, pressure ulcers and intertrigo are very common in long-term residential settings, placing a high burden on this population. Although care receivers share similar risk factors and may be affected by several skin conditions at the same time, there are no associations indicating separate aetiological pathways. REGISTRATION: This study is registered at the German Clinical Trials Register (registration number: DRKS00015680; date of registration: January 29th, 2019) and ClinicalTrials.gov (NCT03824886; date of registration: January 31st, 2019).

General Skin Issues in the Adult Rehabilitation Population.

The skin's ability to function optimally is compromised when skin integrity is altered. The goals for skin management during rehabilitation include maintaining skin integrity, avoiding skin injury, providing early intervention, and comprehensive education for long-term skin management. Assessment of the whole patient as well as the skin is essential. Common issues seen in rehabilitation such as aging skin, incontinence dermatitis, intertrigo/yeast, surgical wounds, and pressure injuries are addressed.

ABA supports AMA regarding monkeypox name change: A satire.

The names of organizations, teams, and medical conditions can elicit controversy when presumedly unintentional defamation of a subset of individuals is perceived. Indeed, this has recently resulted in changing the names of sports teams and diseases. Previously, the ABA (American Baboon Association) solicited the other ABA (American Bar Association), and the drug reaction initially described to as baboon syndrome is now appropriately referred to as symmetrical drug-related intertriginous and flexural exanthema (SDRIFE). Currently, the AMA (American Monkey Association)-with the support of the ABA (American Baboon Association) -has notified the other AMA (American Medical Association) that they consider the name monkeypox unacceptable for this viral infection. The ABA (American Baboon Association) and the AMA (American Monkey Association) are fictional organizations created by the author for the purpose of this satire.

Three cases of symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) induced by proton-pump inhibitors.

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), previously termed drug-related baboon syndrome, is an uncommon drug eruption. It is characterized by symmetrical erythema involving the gluteal and/or inguinal area in association with one other intertriginous area in the absence of systemic involvement. It typically develops a few hours to days after drug exposure. The diagnosis is based on clinical presentation and drug history. The treatment consists mainly of withdrawal of the causative agent; corticosteroids (topical or systemic) are prescribed to accelerate the resolution. We present three cases that appeared after proton-pump inhibitors (PPIs) intake.

Perialar intertrigo in children and adolescents: A multicenter prospective study of 41 cases.

BACKGROUND/OBJECTIVES: We observed isolated cases of perialar intertrigo in children and teenagers that did not appear to correspond to any known clinical entity. The objective of this study was to describe the clinical features of this dermatosis and the clinical characteristics of the patients. METHODS: We conducted a prospective, multicenter cohort study in France from August 2017 to November 2019. All the patients under 18 years of age with chronic perinasal intertrigo were included. A standardized questionnaire detailing the clinical characteristics of the patients and the description of the intertrigo. If possible, a Wood's lamp examination of the intertrigo was done. RESULTS: Forty-one patients were included (25 boys and 16 girls, average age: 12.1 years). Intertrigo was bilateral in 38 patients (93%). The majority of patients had no symptoms (54%). Pruritus was present in 39% of cases. Orange red follicular fluorescence was present in the perialar region on Wood's light examination in 78% of cases with active fluorescence. The presumptive diagnoses suggested by the investigators were acne (24.4%), seborrheic dermatitis (19.5%), rosacea (9.8%), psoriasis (9.8%) and perioral dermatitis (7.3%). No diagnosis was proposed in 22% of the cases. CONCLUSIONS: We describe a previously undescribed clinical sign which is characterized by a chronic bilateral erythematous intertrigo located in the perialar region. It can be isolated or associated with various facial dermatoses.

Secondary data analysis of intertrigo in hospital and geriatric settings: a comparison of prevalence, anatomical locations, and interventions.

BACKGROUND: Skin conditions and dermatological diseases (eg, intertrigo) in older patients are common in clinical practice. In addition to the negative impact on the patient's health, diseases such as intertrigo place a financial burden on the health care system. PURPOSE: The purpose of this secondary data analysis was to compare the prevalence, anatomical locations, and applied interventions of intertrigo in patients in hospitals and geriatric institutions. METHODS: The authors report the outcome of a secondary data analysis of data collected from 2012 to 2016 from the Nursing Quality Measurement 2.0. This is an annually conducted cross-sectional multicenter study. Descriptive statistics and statistical tests were used to analyze the data. RESULTS: Of patients in the hospital, 2.4% (n = 15,152) had intertrigo compared with 3.4% (n = 3743) of patients in geriatric institutions. In general, expert consultation was the least used intervention for the treatment of intertrigo in hospitals (6.1%, n = 359) and geriatric institutions (9.8%, n = 122). CONCLUSION: Independent of the setting, considering the worldwide climate change, the authors expect that the number of patients with intertrigo will be increasing. Therefore, they highly recommend implementing standardized skin assessments for moisture-associated skin damage to identify intertrigo as early as possible. Moreover, as the consultation of experts was seldom used in both settings, advances in the interdisciplinary and interprofessional management of moisture-associated skin damages are needed.

Symmetrical drug-related intertriginous and flexural exanthema (Baboon syndrome) associated with Infliximab: a case-based review.

BACKGROUND: SDRIFE is a rare cutaneous eruption characterized by symmetrical intertriginous dermatitis, caused by delayed Type-IV immune reaction, with several reported drug-triggers. OBJECTIVE: We present a case of SDRIFE associated with infliximab in a 70-year-old female with rheumatoid arthritis, and review cases of SDRIFE associated with TNF-inhibitors. METHODS: A literature review about SDRIFE cases associated with TNF-inhibitors was performed. Articles published in English from inception to January 6th, 2022, restricted to humans, and directly related to this review were included. RESULTS: Ours is the third reported case of SDRIFE associated with TNF-inhibitors, and second with infliximab. SDRIFE can occur anytime during treatment with TNF-inhibitors, and presents with similar clinical and histopathological features as SDRIFE secondary to other drugs. No systemic manifestations have been reported, and the rash resolves after discontinuation of the TNF-inhibitor without any long-term sequelae. CONCLUSION: SDRIFE is benign, and an accurate diagnosis and discontinuation of the responsible drug remain the cornerstone of management.

A randomized controlled trial to compare the effectiveness and safety of adsorbent lotion containing tapioca starch, spent grain wax, Butyrospermum parkii extract, argania spinosa kernel oil, aloe barbadensis, rosehip oil, and allantoin with a low-potency topical corticosteroid in the treatment of intertrigo.

BACKGROUND: Intertrigo is an inflammatory skin-fold condition. Candida infections may occur concurrently or afterward. Topical corticosteroids may reduce inflammation but exacerbate Candida infections. The treatment is contentious. OBJECTIVE: To evaluate the efficacies and safety of adsorbent lotion containing tapioca starch, spent grain wax, Butyrospermum parkii extract, argania spinosa kernel oil, aloe barbadensis, rosehip oil, and allantoin for the treatment of mild-to-moderate intertrigo, relative to 1% hydrocortisone cream. METHODS: This randomized, double-blinded study enrolled 40 intertrigo patients. Twice daily, 20 patients applied adsorbent lotion while the remainder used 1% hydrocortisone cream. Efficacy evaluation, skin biophysical measurements, skin tolerability, safety, and visual analog scale (VAS) patient-satisfaction scores were evaluated at baseline and Week 2. RESULTS: The adsorbent lotion showed higher complete cure rates for color, partial epidermal loss, papules/pustules/vesicles/patches, dryness, and scaling than the corticosteroid without statistical significance. Adsorbent lotion demonstrated significantly higher reduction in pruritus than the corticosteroid treatment. Reduction of erythema level using Mexameter and VAS patient-satisfaction scores were not statistically different between adsorbent lotion and hydrocortisone cream. No adverse effects or superimposed infections were reported. CONCLUSIONS: The anti-inflammatory efficacies of adsorbent lotion and low-potency steroid were equivalent. The lotion was safe and produced excellent pruritus reduction. Patient satisfaction was high.

Symmetrical drug-related intertriginous and flexural exanthema/baboon syndrome induced by traditional Chinese medicine.

BACKGROUND: Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) refers to an uncommon cutaneous adverse reaction that symmetrically involves the buttock and intertriginous areas after systemic exposure to the offending drug and is previously known as baboon syndrome. SDRIFE related with traditional Chinese medicine (TCM) has not been reported. OBJECTIVE: We presented a case of SDRIFE /baboon syndrome induced by TCM, Xi-Huang capsule. METHODS: A 57-years-old man presented with macular erythematous rash mainly on his intergluteal, inguinal, axillary, popliteal regions for a duration of 5 days. The lesions appeared a day after an oral Chinese patent medicine Xi-Huang capsule for arthralgia. Drug eruption was diagnosed. The rash disappeared completely within a week with immediate discontinuation of Xi-Huang capsule and a short term of systemic therapy with glucocorticosteroids. Patch testing was performed on the patient 1 month after complete resolution. He was patch tested with Xi-Huang capsule (5% and 10% in petroleum) using Finn Chambers on Scanpor tape and T.R.U.E. test system. Five heathy volunteers were also patch tested with the same Xi-Huang capsule. RESULTS: Patch testing to 20 common contact allergens including nickel and fragrance were negative. TCM patch test was positive. No positive results were found in five volunteers. Months later, the patient relapsed after an oral herbal Chinese medicine challenge for arthralgia. To avoid the rash recurrence, he stopped taking any Chinese herbal medicine and had complete resolution of disease. CONCLUSION: The Chinese patent drugs for external and oral have unique advantages and have been widely used in many diseases. It is important that dermatologists monitor for clinically significant manifestations of TCM, such as baboon syndrome. Patch testing could help make a definitive diagnosis.

Symmetrical drug-related intertriginous and flexural exanthema like eruption associated with COVID-19 vaccination.

This is a case of symmetrical drug-related intertriginous and flexural exanthema-like eruption following ChAdOx1 nCoV-19 (AstraZeneca-Oxford) vaccination. Investigations, including repeated skin swabs, ruled out an infectious cause. He was subsequently treated with oral prednisolone, which led to a resolution of his symptoms.

Exantema intertriginoso y flexural simétrico por fármacos: presentación de un caso / Symmetrical drug-related intertriginous and flexural exanthema: a case report

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) is a benign, self-limited, immune-mediated, symmetric erythematous rash involving the buttocks and other intertriginous/flexural areas, observed after systemic exposure to a drug in an individual with or without prior sensitization. We present a 70-year old patient, who presented SDRIFE after the administration of piperacillin-tazobactam which improved rapidly after its suspension.

El exantema intertriginoso y flexural simétrico relacionado con fármacos (SDRIFE, por su sigla en inglés) es una erupción eritematosa simétrica, inmunomediada, benigna y autolimitada, que compromete glúteos y otras áreas intertriginosas, flexurales o ambas, y que se observa luego de la exposición sistémica a un fármaco en un individuo con sensibilización previa o sin ella. Se comenta el caso clínico de un paciente de 70 años de edad, que presentó SDRIFE posterior a la administración de piperacilina-tazobactam y que mejoró rápidamente luego de su suspensión.
