RESUMO

Skin reaction is a common toxicity during oncology management, especially followed during the radiotherapy. Its assessment and understanding of the factors influencing its occurrence, is a major issue in the management of patients treated for an early breast cancer (BC). We evaluated 8561 patients during their overall management for a BC. We focus on specific skin toxicities: erythema, fibrosis, telangiectasia and changes of skin colour. These toxicities were assessed at the baseline defined as 0-3-6 (M0), 12 (M12), 36 (M36) and 60 (M60) months. The prevalence of toxicities of interest varied over time, so at M0, 30.4% of patients had erythema while 17.7% of patients had fibrosis. At M60, the prevalence of erythema was 2%, while fibrosis remained stable at about 19%. After adjustments, at M0, there was a significant association between the onset of cutaneous erythema and obesity, the presence of axillary dissection, the type of surgery and the tumour phenotype RH+/HER2+. Concerning fibrosis, a significant association was found, at M12, with the age of the patient, obesity, Charlson score and type of surgery. Concerning the modification of skin colour at M12, we find a link between the age of the patient, obesity, tobacco consumption and alcohol consumption. The prevention of this toxicity is a major issue for the quality of life. Our results allow us to understand the risk of developing skin toxicity in a patient, depending on her intrinsic, tumour or therapeutic characteristics and to implement adapted means of prevention and monitoring.

RESUMO

INTRODUCTION: Chemotherapy drugs can be responsible of several side effects such as hand-foot syndrome (HFS). This syndrome is also called "palmar-plantar erythrodysesthesia" and "acral erythema." Without proper management, it can deteriorate the quality of life of a patient, leading to temporary or definitive stop of chemotherapy. AIM OF THIS STUDY: To identify the epidemiological and clinical characteristics of patients, the risk factors for occurrence and worsening of this syndrome, and the drugs most likely to be responsible of HFS. METHODS: Our study was retrospective, including 42 patients with HFS secondary to a chemotherapy drug. These cases were notified to the National Center of Pharmacovigilance over 7 years. The severity of HFS has been classified according to the NCI-CTCAE v4.0 classification. RESULTS: Our population was composed of 40 women and 2 men. The mean age was 51 years. Docetaxel was the main drug associated with this adverse effect. Hands were involved in all cases and were sometimes associated with other skin surfaces apart from feet. Erythema of the hands and/or feet was present in all patients; it was associated with edema in more than half of the cases. The distribution of different grades according to the NCI-CTCAE classification among the patients was almost equal: 28% Grade 1, 36% Grade 2, and 36% Grade 3. HFS occurred mainly after the first course of chemotherapy with a mean period of 3-4 days. The regression of HFS occurred more rapidly for Grade 1 and Grade 2 compared with Grade 3, especially when assisted by symptomatic treatment. The recurrence rate of HFS for those patients with decreased doses, spacing of cures, and/or symptomatic and prophylaxis treatment was 25%. CONCLUSION: An early detection of HFS, associated with preventive measures, enables patients to continue the chemotherapy.

RESUMO

This study aims to indicate the importance of revising current health recommendations concerning the duration of exposure and individual sensitivity of the skin to solar ultraviolet (UV) radiation. For this purpose, a 16-year data series (2005-2020) of erythemal radiant exposure (Her) and UV index (UVI) for Serbia was analyzed. The UV-related risk was estimated for lighter skin (skin phototypes I-IV) under prolonged exposure on days when maximum UVI was below the recommended protection threshold (UVIlow days, for UVI < 3). Risk assessment was performed for seasonal exposure using satellite-derived data (OMUVBd product) previously validated by ground-based measurements in Novi Sad. The assessment of harmful effects included an analysis of the relation between the daily maximum UVI and the corresponding daily Her, the occurrence of UVIlow days, the exceedance of minimal erythema dose (MED), and the minimum duration of exposure to induce erythema (tMED) for all lighter skin phototypes. It was found that the share of UVIlow days in the total number of days in Serbia increases with the latitude, with the highest percentage in winter (up to 69.454%) and the lowest in summer (up to 3.468%). The results show that the daily Her frequently exceeded the harmful threshold for lighter skin phototypes I-IV (on average by 91.521, 84.923, 70.556, and 56.515%, respectively) on UVIlow days. It was found that prolonged exposure on days with a maximum of UVI = 2 poses a significant risk of erythema for all lighter skin phototypes, even for a duration of 3 h in the middle of the day, as well as medium risk for UVI = 1, and an absence of risk for UVI = 0. The results suggest that health recommendations should be revised, especially in the mid-latitudes, where the share of UVIlow days is large, and in areas where the population is predominantly lighter-skinned.

RESUMO

Skin damage is the most common and most important toxicity during and after radiation therapy (RT). Its assessment and understanding of the factors influencing its occurrence, is a major issue in the management of patients irradiated for an early breast cancer. CANTO is a prospective clinical cohort study of 10 150 patients with stage I-III BC treated from 2012 to 2017 in 26 cancer centres. In our study, we used CANTO-RT, a subcohort of CANTO, including 3480 patients who received RT. We are focus on specific skin toxicities: erythema, fibrosis, telangiectasia and cutaneous pigmentation. The prevalence of toxicities of interest varied over time, so at baseline for early toxicity Month (M) 0-3-6, 41.1% of patients had erythema while 24.8% of patients had fibrosis. At M12 and M36, the prevalence of erythema decreased, respectively, while fibrosis remains stable. The prevalence of telangiectasia increases from 1% to 7.1% from M0-3-6 to M36. After adjustments, we showed an association between the occurrence of skin erythema and obesity; the type of surgery; the presence of axillary dissection; the use of taxane-based CT and the 3D vs IMRT irradiation technique. Regarding fibrosis, an association is found, at M0-3-6, with age at diagnosis, obesity, tobacco and the use of boost. Only obesity and the type of surgery received by the patient remained statistically significant at M12 and M36. In our study we identified several risk factors for acute and late skin reactions. The use of a boost was mainly related to the occurrence of fibrosis while the use of IMRT-type technique decreased the occurrence of skin erythema.

RESUMO

Dermatomyositis (DM) and polymyositis (PM) are rare but serious conditions. The purpose of this study was to investigate, by a review of hospital cases, their epidemiological, clinical and evolutionary profile. We conducted a retrospective study over a 15-year period, between January 2004 and December 2019. All cases with possible or definite diagnosis according to Bohan and Peter's criteria were retained. A total of 14 patients were enrolled (8 DM and 6 PM), with an average age of 48.7 years. Sex ratio was 13F/ 1H. General signs were reported in 71% of cases. Motor deficit affected the girdle muscles in 71% of cases; 85.7% of patients had arthralgia and 14% arthritis. Erythema and periorbital edema were the predominant skin signs. Patients' assessment showed increased sedimentation rate in all cases and increased muscle enzymes in 80% of cases. Antinuclear antibodies were positive in 63% of cases. Muscle biopsy objectified inflammatory myositis in 75% of cases. Heart disease was reported in 14% of cases and lung disease in 21%. Cancer was found in 21.4% of cases. All patients received corticosteroid therapy. Improvement was reported in 88% of patients, with a relapse in 4 patients. In our context, DM is more frequent than PM, with a clear female predominance. Pulmonary disease is a heavy complication. Its association with cancers occurs commonly, hence the need for a systematic cancer screening at diagnosis and follow-up.

RESUMO

BACKGROUND: Neither dupilumab-associated facial erythema nor neck erythema was reported in phase 3 clinical trials for the treatment of atopic dermatitis, but there have been a number of reports of patients developing this adverse event in clinical practice. OBJECTIVE: To outline all cases of reported dupilumab-associated facial or neck erythema to better characterize this adverse event, and identify potential etiologies and management strategies. METHODS: A search was conducted on EMBASE and PubMed databases. Two independent reviewers identified relevant studies for inclusion and performed data extraction. RESULTS: A total of 101 patients from 16 studies were reported to have dupilumab-associated facial or neck erythema. A total of 52 of 101 patients (52%) had baseline atopic dermatitis facial or neck involvement and 45 of 101 (45%) reported different cutaneous symptoms from preexisting atopic dermatitis, possibly suggesting a different etiology. Suggested etiologies included rosacea, allergic contact dermatitis, and head and neck dermatitis. Most commonly used treatments included topical corticosteroids, topical calcineurin inhibitors, and antifungal agents. In the 57 patients with data on the course of the adverse events, improvement was observed in 29, clearance in 4, no response in 16, and worsening in 8. A total of 11 of 101 patients (11%) discontinued dupilumab owing to this adverse event. LIMITATIONS: Limited diagnostic testing, nonstandardized data collection and reporting across studies, and reliance on retrospective case reports and case series. CONCLUSION: Some patients receiving dupilumab develop facial or neck erythema that differs from their usual atopic dermatitis symptoms. Prompt identification and empiric treatment may minimize distress and potential discontinuation of dupilumab owing to this adverse event.

RESUMO

This study investigates the occurrence of erythematous lip lesions in a captive sun bear population in Cambodia, including the progression of cheilitis to squamous cell carcinoma, and the presence of Ursid gammaherpesvirus 1. Visual assessment conducted in 2015 and 2016 recorded the prevalence and severity of lesions. Opportunistic sampling for disease testing was conducted on a subset of 39 sun bears, with histopathological examination of lip and tongue biopsies and PCR testing of oral swabs and tissue biopsies collected during health examinations. Lip lesions were similarly prevalent in 2015 (66.0%) and 2016 (68.3%). Degradation of lip lesion severity was seen between 2015 and 2016, and the odds of having lip lesions, having more severe lip lesions, and having lip lesion degradation over time, all increased with age. Cheilitis was found in all lip lesion biopsies, with histological confirmation of squamous cell carcinoma in 64.5% of cases. Single biopsies frequently showed progression from dysplasia to neoplasia. Eighteen of 31 sun bears (58.1%) had at least one sample positive for Ursid gammaherpesvirus 1. The virus was detected in sun bears with and without lip lesions, however due to case selection being strongly biased towards those showing lip lesions it was not possible to test for association between Ursid gammaherpesvirus 1 and lip squamous cell carcinoma. Given gammaherpesviruses can play a role in cancer development under certain conditions in other species, we believe further investigation into Ursid gammaherpesvirus 1 as one of a number of possible co-factors in the progression of lip lesions to squamous cell carcinoma is warranted. This study highlights the progressively neoplastic nature of this lip lesion syndrome in sun bears which has consequences for captive and re-release management. Similarly, the detection of Ursid gammaherpesvirus 1 should be considered in pre-release risk analyses, at least until data is available on the prevalence of the virus in wild sun bears.

RESUMO

BACKGROUND: Current field-directed treatments of actinic keratosis (AK), a pre-malignant condition, are often limited by severe local reactions and/or complex treatment. Tirbanibulin, a novel potent anti-proliferative synthetic agent that inhibits tubulin polymerization and Src kinase signalling, is being developed as a convenient, safe, and effective field treatment of actinic keratosis. HYPOTHESIS: A short course of tirbanibulin ointment 1% safely reduces AK lesions. METHODS: In the Phase 1 study, 4 treatment cohorts with forearm lesions received tirbanibulin ointment 1% over 25 or 100 cm2 once daily for 3 or 5 days and were evaluated through day 45. In the Phase 2 study, 2 treatment cohorts with face or scalp lesions received tirbanibulin ointment 1% once daily for 3 or 5 days over 25 cm2 and were evaluated through day 57. Lesion reductions, clearance rates, safety, and pharmacokinetics were assessed. RESULTS: Forearm AK lesions were reduced by day 45 in all Phase 1 cohorts (N=30). Complete AK clearance at day 57 for face/scalp AK lesions in Phase 2 cohorts (N=168) was demonstrated in 43% and 32% of participants of the 5-day and 3-day cohorts, respectively. Adverse reactions were mainly transient mild local erythema and flaking/scaling, pruritus, and pain. Tirbanibulin plasma concentrations were low or undetectable. CONCLUSION: Tirbanibulin ointment 1% was well tolerated and active in AK reduction. Based on activity, the 5-day regimen was selected for Phase 3 development.

RESUMO

Recurrence of breast cancer is a predominant fear for patients who were treated for breast cancer. Acute and late dermatologic effects of radiotherapy are not uncommon and could have similar characteristics to breast cancer recurrence. Thus, it is important to highlight key differences between the clinical and histologic presentations of radiation effects and recurrence. Herein, we present two patients who presented with late dermatologic effects of radiotherapy months to years after treatment, neither of whom had workup consistent with cancer recurrence. We provide clinical and microscopic descriptions of each case and provide a review to differentiate various dermatologic conditions. This report aims to outline potential late dermatologic effects of radiation treatment and emphasise that changes in the breast do not always signal breast cancer recurrence.

RESUMO

BACKGROUND: Nonsurgical rhinoplasty with injectable dermal fillers has become an increasingly popular alternative to surgical procedures, in view of its relative low cost, convenience and rapid recovery, and low risk profile. The safety and efficacy of nonsurgical rhinoplasty remains a relatively contentious and ambiguous matter, given that there are few large-scale series reporting results or complications. This study reports the experience of a single clinician performing nonsurgical rhinoplasty in the largest cohort to date. METHODS: Patient demographics, indications, treatment details, and outcomes of patients treated between March of 2016 and January of 2019 were reviewed. The nonsurgical rhinoplasty technique described previously by Harb was used using hyaluronic acid dermal filler. RESULTS: Nonsurgical rhinoplasty was performed in 5000 patients. The commonest indication was dorsal hump (44 percent). Swelling and erythema were self-limiting side effects encountered in approximately half of patients. Infection was seen in two patients, and localized skin necrosis was observed in three patients. CONCLUSIONS: Nonsurgical rhinoplasty is a safe procedure with positive aesthetic results when performed by an experienced clinician. Knowledge of nasal anatomy, comprehensive training, and use of appropriate materials are key in ensuring safety and results. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

BACKGROUND: Postacne scarring is an unfortunate and frequent complication of acne, with varied morphological forms and associated significant psychological distress to patients. AIM OF THE WORK: To evaluate the efficacy and safety of plasma gel injection alone and in combination with microneedling in treatment of atrophic postacne scars. PATIENTS AND METHODS: Sixty patients with atrophic postacne scars were enrolled in this single blinded randomized controlled study. The patients were divided into three groups with 20 patients being treated with intradermal injection of plasma gel, 20 patients treated with dermaroller, and 20 patients subjected to combined plasma gel and dermaroller. Patients received four sessions at monthly intervals and were evaluated by clinical, histopathological, and immunohistochemical analysis. RESULTS: There was statistically significant improvement in postacne scars after treatment in all studied groups with variable degrees; the combined technique showed the best clinical improvement in postacne scars. There was an increase in newly formed collagen and elastic fibers with more organized and condensed bundles after the end of treatment. CONCLUSION: Plasma gel showed a remarkable improvement for most patients after one session, providing a quick and easy solution for acne scars. The combination of dermaroller and plasma gel potentiated its effect with more improvement in scars.

RESUMO

Bleomycin is widely used as an off-label treatment for various dermatologic indications. However, a much-needed critical appraisal of the currently available evidence is lacking. We therefore evaluated the quality of clinical evidence for the efficacy and safety of intralesional bleomycin treatment for dermatologic indications with the aim to provide evidence-based recommendations for clinical practice. The PubMed, Embase, Medline Ovid, Web of Science, Cochrane Central, and Google Scholar databases were systematically searched. Two authors independently selected relevant studies according to predefined inclusion and exclusion criteria. We assessed the methodologic quality with the Cochrane Collaboration risk-of-bias assessment tool and selected 10 randomized clinical trials and 15 clinical controlled trials. Treatment indications included common warts, nonmelanoma skin cancer, cutaneous metastases, keloid and hypertrophic scars, and hemangioma. Intralesional bleomycin treatment showed significantly higher cure rates for warts compared with other treatments. Local adverse events included erythema, blackening, eschar formation, and superficial ulceration. None of the studies reported systemic adverse events. Methodologic quality of the studies was generally low. Consequently, no firm recommendations can be made for intralesional bleomycin treatment in clinical practice. However, this review suggests that intralesional bleomycin is a successful and well-tolerated treatment for recalcitrant warts.

RESUMO

BACKGROUND: Picosecond lasers have become very popular in the treatment of hyperpigmentation. OBJECTIVE: Evaluating the efficacy and safety of picosecond 755-nm laser in treatment of nevi of Ota (NO) and Hori's nevi (HN) in Asians with Fitzpatrick skin Types III/IV. METHODS: A retrospective review of patient records at the National Skin Center, Singapore, from 2015 to 2017. Three independent blinded dermatologists assessed pre-and-post treatment photographs using the physician's global assessment (PGA) score (0-clear, 1-almost clear, 2-mild, 3-moderate, and 4-severe). RESULTS: There were 18 cases of NO and 11 cases of HN. Mean treatment sessions were 2.22 (NO; range 1-6) and 3.82 (HN; range 1-6). In the NO group, mean pre-and-post treatment PGA scores were 3.1 and 1.3, respectively (1.8 point change, p-value 0.0002), and average fluence used was 2.02 J/cm (range: 1.02-2.38). In the HN group, mean pre-and-post treatment PGA scores were 2.6 and 1.1, respectively (1.5 point change, p-value 0.004), and average fluence was 2.08 J/cm (range: 1.98-3.40). Eleven patients (37.9%) experienced postlaser erythema, and 1 (3.4%) patient developed transient postlaser hypopigmentation. No permanent hyper/hypopigmentation was seen. CONCLUSION: The picosecond 755-nm laser is effective in the treatment of dermal pigmentary conditions in Asians with Fitzpatrick skin Types III/IV, with minimal risk of postlaser complications, and compared with the center's past experience with the Q-switched nanosecond 1064-nm laser, results in faster and more effective pigment clearance.

RESUMO

OBJECTIVE: Sarilumab is a human monoclonal antibody that blocks IL-6 from binding to membrane-bound and soluble IL-6 receptor-α. We assessed the long-term safety of sarilumab in patients from eight clinical trials and their open-label extensions. METHODS: Data were pooled from patients with rheumatoid arthritis who received at least one dose of sarilumab in combination with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs; combination group) or as monotherapy (monotherapy group). Treatment-emergent adverse events (AEs) and AEs and laboratory values of special interest were assessed. RESULTS: 2887 patients received sarilumab in combination with csDMARDs and 471 patients received sarilumab monotherapy, with mean exposure of 2.8 years and 1.7 years, maximum exposure 7.3 and 3.5 years, and cumulative AE observation period of 8188 and 812 patient-years, respectively. Incidence rates per 100 patient-years in the combination and monotherapy groups, respectively, were 9.4 and 6.7 for serious AEs, 3.7 and 1.0 for serious infections, 0.6 and 0.5 for herpes zoster (no cases were disseminated), 0.1 and 0 for gastrointestinal perforations, 0.5 and 0.2 for major adverse cardiovascular events, and 0.7 and 0.6 for malignancy. Absolute neutrophil counts <1000 cells/mm3 were recorded in 13% and 15% of patients, respectively. Neutropenia was not associated with increased risk of infection or serious infection. Analysis by 6-month interval showed no signal for increased rate of any AE over time. CONCLUSION: The long-term safety profile of sarilumab, either in combination with csDMARDs or as monotherapy, remained stable and consistent with the anticipated profile of a molecule that inhibits IL6 signalling.

RESUMO

OBJECTIVE: The objective of our study was to present the results and safety profile of fractional 1064 Q-switched Nd: YAG laser treatment in skin rejuvenation in Indian patients with Fitzpatrick skin type III-VI. MATERIALS AND METHODS: We studied our clinical data of 252 patients who underwent treatment for facial skin rejuvenation with the Q switched Nd:YAG laser 1064 wavelength, using the fractional mode of 5mm spot size with fluences from 1.2 J ~ 2 J/cm2 and the energy ranging from 300-500 mJ, a repetition rate of 7Hz and pulse duration of 8 ns for 6 sessions at two weekly intervals. We evaluated results with the aid of clinical photography taken before start of treatment, on 3rd and 5th sessions along with patient satisfaction and dermatologist assessment scores. Any adverse events were also recorded. RESULTS: At the end of 6 sessions, both patients and dermatologists reported visible improvement in skin texture and tone. The laser sessions resulted in an immediate improvement in skin texture and tone in the first session itself that increased over 3 sessions and then stabilized. Transient erythema was reported in a few cases. No hypo- or hyperpigmentation were noted. CONCLUSIONS: The 1064 QSNYL is popularly used for skin rejuvenation especially in the Asian countries. But there is lack of substantial clinical data to validate the clinical results. We present the first study that shows the fractional 1064 Qswitched ND:YAG laser is a safe and effective option for skin rejuvenation in skin types III-VI.

RESUMO

BACKGROUND: Striae distensae have notoriously been difficult to treat due to their extensive involvement of nonfacial skin. Microneedling with its lack of thermal injury during microneedling treatment renders it a viable treatment option in darker skin tones and nonfacial regions due to the reduced risk of postinflammatory hyperpigmentation. OBJECTIVE: To describe the clinical results and side effects of microneedling in a series of 25 individuals with striae distensae. MATERIALS AND METHODS: Twenty-five consecutive adults (SPT I-V) with striae distensae involving the trunk and extremities were treated using a microneedling device. No additional treatments (topical or intralesional) were applied. Two assessors blinded to treatment protocol rated clinical improvement of striae on a 5-point scale. Side effects were monitored and tabulated. RESULTS: Patients received 1 to 3 consecutive monthly treatments. All striae improved at least 50% after an average of 1.8 treatments, and 28% of patients demonstrated more than 75% clinical improvement. Striae in thicker skin regions (e.g., buttocks/thighs) showed comparable clinical improvement than those in thinner skin areas (e.g., breasts) and did not require additional treatment sessions. Side effects were limited to transient erythema in all skin phototypes. No infections or dyspigmentation were observed. CONCLUSION: The clinical results obtained in this study support the safe and effective treatment of striae distensae with microneedling in light and dark skin tones in various body locations. Standardization of treatment protocols are anticipated with further (ongoing) studies.

RESUMO

BACKGROUND: Silicone-polytetrafluoroethylene composite implants are fast gaining popularity in Asian rhinoplasty. Nonetheless, implant displacement, erythematous reactions, and infections still occur in the authors' patient group during long-term follow-up. OBJECTIVES: The authors reported successful experience of combining the utilization of silicone-polytetrafluoroethylene composite implants with onlay temporal fascial grafts to circumvent these complications. METHODS: Sixty-four patients of Asian ethnicity underwent augmentation rhinoplasty utilizing an I-shaped composite implant with an onlay fascial graft from January 2015 to June 2018, with a mean follow-up period of 13.5 months. This patient group was compared with a control group of 177 Asian patients who underwent augmentation rhinoplasty utilizing the same composite implant but without the addition of a fascial graft; the control group was treated from February 2012 to June 2015, with a mean follow-up of 42.0 months. Complications were compared between these 2 patient groups, specifically focusing on malposition/deviations, erythema, and infections. RESULTS: There was a marked decrease in complication rates with the addition of an onlay temporal fascial graft to cover the composite implant in augmentation rhinoplasty (7.8% vs 14.7%) as well as the rate of erythematous reactions (0% vs 6.2%, P = 0.04), infection (1.6% vs 1.1%), and implant malposition/deviation (0% vs 4.5%). Harvesting the temporal fascia and fashioning the onlay graft added an additional 33 minutes on average per procedure. No donor site morbidity was encountered. CONCLUSIONS: Although the operative time increased, the benefits of adding onlay fascial grafts to silicone-polytetrafluoroethylene implants in alloplastic augmentation rhinoplasty outweigh the drawbacks, as evidenced by the decrease in erythematous reactions.
