RESUMEN

Fixed drug eruption (FDE) is a cutaneous drug reaction characterised by recurrent skin lesions occurring at the same site after each exposure to a causative agent. There is currently limited evidence in the paediatric population. The objective of this systematic review is to investigate the clinical features, causative agents and management of paediatric FDE. A systematic search of the English and French literature on paediatric FDE was conducted using the Medline and Embase databases. After full-text article review, 92 articles were included, representing a total of 233 patients. Antibiotics were the most frequent triggering agents, mainly sulfonamides (65.0% of antibiotics). Systemic symptoms were rare, and most patients only received supportive therapy. One hundred and six patients (106) performed a test to confirm the causative agent. Of these, 72.6% had oral provocation tests (OPTs) and 28.3% had patch tests. The patient's age, presence of bullous lesions and mucosal lesions were similar between tested and untested patients. It did not seem to influence the decision to perform OPTs. Paediatric FDE is a non-severe skin drug reaction. Antibiotics were the most reported triggering agents. Drug testing, including oral provocation test, was safely performed in the paediatric population.

RESUMEN

BACKGROUND: A number of cutaneous manifestations and adverse cutaneous reactions have been associated with COVID-19 infection and vaccine. OBJECTIVES: A Lebanese national registry was established to characterize the dermatologic manifestations and adverse cutaneous reactions associated with COVID-19 infection and vaccination in a sample of the Lebanese population. METHODS: An observational cross-sectional study was conducted via a web-based clinical form distributed to physicians wishing to report their cases from May 2021 till May 2022. RESULTS: In total, 142 patients were entered in the registry, of which 133 were adults and nine were pediatric patients. The main dermatological manifestations reported with COVID-19 infection in the adult group were urticaria (32.9%), telogen effluvium (21.4%), morbilliform (10%), and papulosquamous (8.6%) eruptions. Urticaria was the most common adverse cutaneous reaction to the vaccine (33%). Interestingly, herpes zoster was triggered in 12 patients post vaccination in our series with this finding more frequently seen in patients above the age of 41 (P = 0.013). In the pediatric group, the most reported dermatological findings associated with COVID-19 infection were malar erythema (25%) and telogen effluvium (25%). One 16-year-old patient developed lichen planus after one dose of a COVID-19 vaccine. No deaths were reported in both age groups. CONCLUSION: This Lebanese registry adds more robust evidence that clinical manifestations of the COVID-19 virus and vaccine are diverse. More studies are necessary to establish the pathophysiology of these dermatological findings in the context of COVID-19 infection and vaccination.

RESUMEN

Background: Melasma is a widespread condition that affects people of many ethnicities and is prevalent in the Middle East. To date, the therapeutic arsenal is still not effective, especially in countries with high ultraviolet light index. New treatment options are needed. Objective: The aim of this pilot study was to assess the efficacy of topical tranexamic acid (TA) 2% combined with vitamin C 2% in the treatment of resistant melasma in the Mediterranean region. Methods: This prospective interventional pilot study included 10 women, aged 18 to 55 years, with resistant melasma. Intervention consisted in application of a topical formulation containing 2% TA and 2% vitamin C, every night for eight weeks. The primary outcome was the Melasma Area and Severity Index (MASI) score measured at baseline and at Weeks 4 and 8. Melasma Quality of Life Scale (MelasQoL) and Physician Global Assessment (PGA) were used at baseline and at Weeks 4 and 8 of treatment, and they were set as the secondary outcomes. Results: The mean MASI score varied from 12.76±3.91 at baseline to 7.00±4.85 at Week 4 (p<0.01) then to 3.39 ± 1 at Week 8 (p=0.03). The mean MelasQoL decreased from 35.2 ± 16.03 at baseline to 28.8 ± 12.96 at Week 4 (p<0.01) then to 24.9±13.96 at Week 8 (p=0.14). The PGA increased between Weeks 4 and 8 passing from 2.2±0.79 to 2.4±1.07. No major side effects were reported. Conclusion: Our pilot study demonstrated the possibility of a topical combination of TA 2% and vitamin C 2 %, which may be a useful therapeutic strategy in the treatment of resistant melasma in the Middle east, a region of the world with high UV index. This combination treatment is a safer alternative to dangerous bleaching treatments that are still being used.

RESUMEN

OBJECTIVE: The aims of this study were to determine whether zinc supplementation affects botulinum toxin's effect and longevity and to establish a transition from the molecular to the clinical aspect. METHODS: We conducted a systematic review in which we included all published studies on PubMed and Embase using the combination of the following terms: "zinc" AND (botox OR botulinum OR onabotulinumtoxinA OR abobotulinumtoxinA OR incobotulinumtoxinA). RESULTS: From the 260 yielded articles, 3 randomized control trials and 1 case report were retained. Three of them found a significant improvement with zinc supplementation in the toxin's effect and longevity. This was observed in neurological conditions and cosmetic uses. CONCLUSIONS: Zinc supplementation could be an interesting asset in the potentialization of botulinum neurotoxin effect and longevity. Larger clinical trials and objective measurement tools should be used to further defining the role of zinc in maximizing botulinum neurotoxin effect.

RESUMEN

BACKGROUND: In 2015, a major achievement in vitiligo research was the development of an internationally agreed upon core outcome domain set for randomized clinical trials (RCTs). Three outcomes were identified as being essential: repigmentation, side-effects/harms and maintenance of gained repigmentation. Four items were further recommended for inclusion. The following recommendations then followed: repigmentation should be assessed by measuring the percentage of repigmentation in quartiles (0-25%, 26-50%, 51-79%, 80-100%) and cosmetic acceptability of the results should be assessed using the Vitiligo Noticeability Scale. OBJECTIVES: The primary objective of this study was to assess uptake of the core outcome domain set for RCTs in vitiligo. Secondary objectives were to update the systematic review on outcomes reported in vitiligo RCTs, and to assess whether repigmentation and cosmetic acceptability of the results were measured using the above-mentioned recommended scales. METHODS: We searched PubMed, Cochrane Library (CENTRAL and Systematic Reviews) and ClinicalTrials.gov for vitiligo RCTs between November 2009 and March 2021. Screening and data extraction were independently performed on title and summary by two researchers. All outcomes and outcome measures reported in eligible RCTs were retrieved and collated. RESULTS: In total, 174 RCTs were identified: 62 were published between 2009 and 2015, and 112 were published between 2016 and 2021.Thirty-eight different outcomes were reported. Repigmentation was the primary outcome in 89% of trials (150 of 169). Forty-nine different tools were used to measure repigmentation. Side-effects and harms were reported in 78% of trials (136 of 174). Maintenance of gained repigmentation was reported in only 11% of trials (20 of 174) and duration of follow-up varied greatly from 1 to 14 months. Cosmetic acceptability of the results and cessation of disease activity were assessed in only 2% of trials (four of 174). Quality of life of patients with vitiligo was assessed in 13% of trials (22 of 174). Finally, only 11 of 112 RCTs (10%) published between 2016 and 2021 reported all three essential core outcome domains (repigmentation, side-effects and maintenance of gained repigmentation) and none of the trials reported both essential and recommended core outcome domains. CONCLUSIONS: Efforts are still needed to close the gap between set recommendations and RCT outcome reporting.

RESUMEN

Oral isotretinoin remains the most effective treatment for acne. The aim of this retrospective single-center cohort study was to estimate the prevalence of adverse events with the different oral isotretinoin brands used in acne treatment. The population consisted of all patients who consulted for acne between January 2015 and January 2020. The inclusion criterion was the initiation of treatment with oral isotretinoin. The exclusion criteria were the use of two or more brands during the same course of treatment and previous treatment with oral isotretinoin. Statistical analysis was carried out using Chi-square and Mann-Whitney tests. We analyzed 468 patients of whom 68.6% were female. The median age was 21 years. The median weight was 65 kg. The treatment was Roaccutane®, Curacné®, Acnotren®, Isosupra®, Contracné®, or Acnogen® in 44.2%, 28%, 14.5%, 10.5%, 1.7% and 0.4% of cases, respectively. Xerosis was the most frequently reported side effect regardless of the brand. The highest frequencies of hypercholesterolemia (25.6%) and eczema (13%) were noted with Roaccutane®; hypertriglyceridemia (16.8%), epistaxis (9.9%) and fatigue (3.1%) with Curacné®; excessive sweating (4.1%) and headache (4.1%) with Isosupra®; and abnormal liver function tests (11%) with Acnotren®. We found a significant correlation mainly between abnormal ASAT and Acnotren® (p = 0.009), hypercholesterolemia and Roaccutane® [OR = 1.652 (95% CI 1.056-2.585)], hypertriglyceridemia and higher body weight (p = 0.004). Factors related to the drug brand and to characteristics of acne patients could explain the variability in the prevalence of some adverse events.

RESUMEN

BACKGROUND: Lichen planus (LP) is a chronic inflammatory disorder usually occurring in middle-aged adults. Data are scarce in the pediatric population. OBJECTIVE: To describe the patients' characteristics, clinical presentation, and management of pediatric LP. METHODS: A systematic literature review of pediatric LP was performed in the Medline and Cochrane databases up to February 1, 2020. Demographic and clinical data were extracted for analysis, in addition to laboratory and histology findings, treatments used, and response to treatment. LP pemphigoides (LPP) was further pooled for a subcategory analysis. RESULTS: One hundred and sixty-four articles were included representing 985 patients. The most common country of origin was India. The most common clinical signs were flat-topped papules (51%); the linear variant was present in 9%. Oral involvement was present in 22%. The most commonly used treatment was topical corticosteroids followed by systemic corticosteroids. The mean duration of treatment was 124.4 days. LPP patients had a short disease duration before diagnosis (4.1 months, P < 0.001) and failed previous treatment more frequently (P < 0.001). Systemic corticosteroids were more often prescribed in this subgroup (75%, P < 0.001) with more recurrence after treatment (31%, P = 0.048). LIMITATIONS: Lack of randomized controlled studies, in addition to publication bias. CONCLUSION: In children, LP had a wide polymorphous clinical presentation, and the reported cases were mostly from India. The linear variant was more common and the oral mucosa was less affected in children. LPP, a rare subtype in children, was treated with systemic corticosteroids and recurred more frequently.

RESUMEN

BACKGROUND: Acne is highly prevalent among teenagers and young adults, with proven negative psychological and emotional impact. To our knowledge, no study has been conducted to quantify the repercussions of acne on quality of life (QoL) and self-esteem in Lebanon. OBJECTIVE: This study aimed to highlight the effect of acne treatment on QoL and self-esteem of Lebanese adolescents and young adults. METHODS: In this observational prospective study, patients between 15 and 40 years old with moderate-to-severe acne were allocated to one of two treatment groups (isotretinoin vs. systemic antibiotics combined with topical treatments) and followed for a period of 6 months. The effect of acne on QoL was measured using the Dermatology Life Quality Index, Cardiff Acne Disability Index, and Rosenberg Self-esteem Scale before treatment initiation (T1), after 3 months (T2), and after 6 months (T3). A multivariate analysis of covariance model was used. RESULTS: Sixty-two patients were included, of whom 79% were female and 61.3% had moderate acne. Fifty-five percent of patients were treated with systemic antibiotics combined with topical treatments, and 45% received isotretinoin. Mean scores of Cardiff Acne Disability Index, Dermatology Life Quality Index, and Rosenberg Self-esteem Scale at T1 were comparable between the two groups. A significant improvement was noticed in both groups at T2 and T3. The multivariate analysis of covariance model showed an interaction of time and age that concerned 25- to 40-year-old patients in both groups, who were the most negatively affected by acne at T1 and improved the most at T3. CONCLUSION: This study demonstrated the equivalence between acne treatments in improving QoL and revealed the social obstacle that acne creates and its recrudescence in the subgroup of women of childbearing age.

RESUMEN

BACKGROUND: Human papilloma virus (HPV) infection is the most common sexually transmitted disease worldwide and the main cause of genital warts. Clear recommendations for the management of urethral warts, which are often hard to detect and difficult to treat, are still lacking. OBJECTIVE: To summarize all available data describing treatment modalities of urethral warts, compare their efficacy and side effects, and provide physicians a treatment strategy outline. MATERIAL AND METHODS: Till June 2020, we conducted a systematic review of articles studying the different treatment modalities of urethral condylomas. A chi-square test was used to compare the recurrence rates between treatment modalities, the complete clearance rates at first follow-up and the rates of adverse events. RESULTS: A total of 26 articles with 1730 patients were included in our review. 61 % of patients were deemed completely cured on the first follow-up while 21 % recurred. 5-aminolevulinic acid (ALA) mediated photodynamic therapy (PDT) was the most common treatment and yielded the lowest recurrence rate (7.5 %) followed by laser therapy (24 %) and topical therapy (31 %) (p < 0.01). ALA-PDT resulted in a higher rate of clearance on follow up (96 %) compared to laser therapy (69 %) and topical therapy (14 %) (p < 0.01). Adverse events were more frequent in the ALA-PDT group (69 %) compared to laser therapy (28 %) and topical treatment (30 %) (p < 0.01). CONCLUSION: ALA-PDT appears to be the most effective treatment of urethral condylomas in term of clearance and recurrence rate, but with a higher risk of adverse events. Management should be tailored to the type of lesion found at presentation.

RESUMEN

BACKGROUND: Acquired ungual fibrokeratomas (AUFKs) are benign recurrent fibrokeratotic tumors of the nail unit of uncertain etiology. Little is known about the optimal modality to successfully treat these lesions. No systematic review addressing ungual fibrokeratomas has been published to date. OBJECTIVES: The aim of this study is to summarize all the published data regarding diagnostic and therapeutic challenges of AUFKs. METHODS: On August 9, 2019, a systematic search of Medline and Cochrane databases was conducted. All the studies describing the treatment of ungual fibrokeratomas, procedure description, pathological findings, outcome, and follow-up period were included in this review. RESULTS: After full-text article review, 103 articles were included, representing a total of 78 lesions. The commonly used treatments for fibrokeratomas were complete tumor resection (90.5%), shave excision (8.3%), and cryotherapy (1.2%). Complete surgical excision yielded the highest cure rate among all treatment modalities (90.8%) compared to partial surgical excision (28.6%) and cryotherapy (0%). The mean follow-up period was 12.1 months (1-144). CONCLUSION: Complete surgical removal preserving the matrix showed the highest cure rates and should be considered as first-line treatment for AUFKs. Future adequately designed randomized control trials are warranted to compare different treatment modalities.

RESUMEN

BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe cutaneous adverse drug reaction with systemic symptoms. This study aims to investigate clinical features, causative drugs, and available treatments for pediatric DRESS, particularly for relapsing cases. METHODS: A systematic search of the English and French literature on pediatric DRESS was conducted using the Medline, Embase, and Cochrane collaboration databases. Confirmed cases of pediatric DRESS fulfilling the RegiSCAR diagnostic criteria with a probable or a definite diagnosis were included. RESULTS: After full-text article review, 144 articles were included, representing a total of 354 pediatric patients with a mean age of 8.8 years. The mean time from the drug intake until the onset of the first symptom was 18.9 days. Antiepileptic drugs were the main trigger, followed by anti-infectious agents. Relapsing DRESS was reported in 17 children. In comparison to non-relapsing cases, relapsing patients had more comorbidities. The initial clinical presentation was more commonly erythroderma. Facial edema, fever, and enlarged lymph nodes in more than two sites were more commonly found in relapsing cases. Systemic steroids were more frequently administered. CONCLUSION: Pediatric DRESS is a potentially severe adverse drug reaction. Antiepileptic agents are the most common causative agents. Fever, facial edema, lymph node enlargement, and pharyngeal and visceral involvement predicted DRESS reactivation in children. Corticosteroids were the mainstay of treatment.

RESUMEN

BACKGROUND: Keratosis pilaris (KP) is a common hereditary keratinization disorder. Keratosis pilaris rubra and KP atrophicans faciei are less frequent variants of the disease. Topical treatments often yield ineffective and temporary results. OBJECTIVE: The objective of this article is to review and assess all the studies that used light and laser devices to treat KP and its variants. MATERIAL AND METHODS: On January 15, 2017, an online search of the MEDLINE, Embase, and Cochrane databases was performed using the following combination of keywords: "keratosis pilaris" and "treatment." RESULTS: Seventeen studies related to light and laser treatments were retained for analysis. The total number of treated patients was 175. Of which, 22 patients had KP atrophicans faciei, 17 patients had KP rubra, and 136 patients had KP. CONCLUSION: Light and laser devices have been emerging as promising therapeutic options for a disfiguring disease that still lacks, until today, an effective long-term treatment.

RESUMEN

BACKGROUND: Nontuberculous mycobacterium (NTM) infection following cosmetic procedures usually results from inadequate sterile techniques and contamination from nonsterile water. These infections are difficult to diagnose and treat. OBJECTIVE: This study aimed to describe the characteristics of NTM infections acquired after an aesthetic procedure, identify high-risk patients and high-risk cosmetic procedures, and provide a diagnostic and management algorithm for NTM infections occurring after cosmetic procedures. METHODS: On December 20, 2017 an online search of the Medline database was done. All articles describing NTM infection in cosmetic procedures were included in this review. RESULTS: In total, 92 patients with a mean age of 38.35 years were included in this review. Cosmetic procedures performed in the Dominican Republic were the most common source of infection and were noted in 33 patients. The procedure that resulted in the highest proportion of the infections was mesotherapy (34%). In most of the cases, the diagnosis was missed at the initial presentation and a short course of inadequate antibiotics was unsuccessful. CONCLUSION: Nontuberculous mycobacterium infections are hard to diagnose and difficult to treat, sometimes leading to severe irreversible sequalae. Aesthetic practitioners should know when to suspect and how to prevent, diagnose, and treat NTM infections.

RESUMEN

BACKGROUND: Erythema multiforme (EM) is an acute inflammatory mucocutaneous condition. EM is rarely described in children and infants. OBJECTIVE: To investigate the triggers, clinical manifestations, and treatment of pediatric EM. METHODS: Systematic literature review of pediatric EM. RESULTS: After full-text article review, we included 113 articles, representing 580 patients. The mean age was 5.6 years, ranging 0.1-17 years. Infectious agents were the main triggers: herpes simplex virus (HSV) in 104 patients (17.9%) and Mycoplasma pneumoniae in 91 patients (15.7%). In total, 140 cases (24.1%) were drug-related and 89 cases (15.3%) had other triggers, such as vaccines (19 patients, 3.2%). In total, 229 patients had EM major (39.5%). Treatment was supportive care only (180 patients, 31.1%), systemic corticosteroids (115 patients, 19.8%), antivirals (85 patients, 14.6%), and antibiotics (66 patients, 11.3%), mostly macrolides (45 patients, 7.7%). Long-term sequelae were rare (1.3%). Pediatric EM was reported in 19 infants (3.2%). The main trigger was vaccination (9 patients). Infantile EM was EM major in 2 cases and EM minor in 17. Infants were less prone to develop EM major than older children (P < .01). Pediatric EM was recurrent in 83 cases (14.3%), which was triggered by HSV in 36 patients (61%). Recurrence affected older children. LIMITATIONS: Potential confusion between Steven Johnson syndrome and EM major in addition to publication bias. CONCLUSION: Pediatric EM is a rare disease, mainly triggered by infections. This condition can affect all mucosal surfaces, most commonly the oral mucosae. The diagnosis is clinical, and management relies on supportive care. Vaccines are a particular trigger in infants. Recurrent cases are most commonly linked to HSV. Dermatologists and pediatricians should be aware of this potentially recurrent and severe condition.

RESUMEN

No previous study has objectively evaluated the effect of different forehead injection patterns on the eyebrow height and forehead lines. The patients were divided into three groups. Botulinum toxin was injected into both the lateral and medial eyebrow depressors in all groups. The frontalis was injected using either a V-pattern (group 1), a middle horizontal pattern (group 2), or a high horizontal pattern (group 3). Objective eyebrow measurements were performed using standardized preinjection and postinjection photographs. Validated photonumeric scales were used to assess the forehead lines. Fifteen patients (30 eyebrows) were included in each group. In all of the groups, 2 weeks after injection, the brow was lower at all the measured positions, with the exception of the lateral brow edge, which was higher in the three injection patterns. No difference was found when comparing group 1 to groups 2 and 3. The middle forehead injection pattern lowered the eyebrow more than the upper forehead injection pattern. The three techniques improved the forehead lines at rest and with contraction. The forehead lines with contraction were more improved in group 1 compared with both groups 2 and 3. Each forehead injection pattern yielded different results on forehead lines and eyebrow position. Upper forehead injections were less effective on forehead lines but prevented eyebrow ptosis. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, II.

RESUMEN

BACKGROUND: Zosteriform rash in cancer patients provides objective clues to the process of reinnervation of the reconstructed breast. This rash should also raise suspicion for metastasis, which can be confused with herpes zoster. OBJECTIVES: The aims of this study were to explain the reconstruction flap sensory reinnervation mechanism based on the clinical findings and provide a diagnostic and management algorithm of zosteriform rash in breast cancer patients. METHODS: On November 15, 2017, we conducted a search of published articles in MEDLINE and Cochrane databases. All the articles describing a zosteriform rash in a patient with a history of breast cancer were included in this review. RESULTS: Eleven articles from the literature and 1 case from our practice were selected for inclusion in this systematic review. Five patients had a breast reconstruction with a flap. The flap skin was affected by the rash in 4 of these patients, providing an objective proof of the reinnervation of the reconstructed breast. In 6 patients, the presentation was typical, and the diagnosis of herpes zoster was made without additional diagnostic testing. In 4 cases, the eruption was atypical, and a biopsy was done to confirm the diagnosis of a cancer metastasis. In 2 patients, the rash was multidermatomal, and a polymerase chain reaction was done to confirm the diagnosis of disseminated herpes zoster. CONCLUSIONS: Zoster reactivation in breast reconstructed patients is an objective proof of the reinnervation of the skin flap. Moreover, zosteriform rash in cancer patients should raise suspicion for metastasis, which can be confused with herpes zoster.

RESUMEN

BACKGROUND: Microbotox consists of the injection of microdroplets of botulinum toxin into the dermis to improve the different lower face and neck aging components. No clinical trial has evaluated its effect on the different face and neck components and no study has compared it to the "Nefertiti lift" procedure. METHODS: In this crossover study, patients previously treated with the Nefertiti lift were injected using the microbotox technique. Using standardized preinjection and postinjection photographs, the jowls, marionette lines, oral commissures, neck volume, and platysmal bands at maximal contraction and at rest were assessed with validated photonumeric scales. In addition, the overall appearance of the lower face and neck was evaluated by the Investigators and Subjects Global Aesthetic Improvement Score. Pain and patient satisfaction rates were also evaluated. RESULTS: Twenty-five of the 30 patients previously treated with the Nefertiti technique were injected with a mean dose of 154 U using the microbotox technique. Platysmal bands with contraction, jowls, and neck volume reached a statistically significant improvement. The microbotox technique improved the jowls and the neck volume more than the Nefertiti technique, whereas the platysmal bands at rest and with contraction were more improved by the Nefertiti technique. One hundred percent of patients were satisfied with both techniques and rated themselves as improved. CONCLUSIONS: The microbotox technique is a useful, simple, and safe procedure for lower face and neck rejuvenation. It is mainly effective in treating neck and lower face soft-tissue ptosis, in contrast to the Nefertiti technique, which is more effective on platysmal bands. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
