RESUMEN

Drug-associated bullous pemphigoid has been shown to follow long-term gliptin (dipeptidyl-peptidase 4 inhibitors) intake. This study aimed at identifying risk factors for gliptin-associated bullous pemphigoid among patients with type 2 diabetes. A retrospective study was conducted in a tertiary centre among diabetic patients exposed to gliptins between the years 2008-2021. Data including demographics, comorbidities, medications, and laboratory results were collected using the MDClone platform. Seventy-six patients with type 2 diabetes treated with dipeptidyl-peptidase 4 inhibitors who subsequently developed bullous pemphigoid were compared with a cohort of 8,060 diabetic patients exposed to dipeptidyl-peptidase 4 inhibitors who did not develop bullous pemphigoid. Based on a multivariable analysis adjusted for age and other covariates, Alzheimer's disease and other dementias were significantly more prevalent in patients with bullous pemphigoid (p = 0.0013). Concomitant use of either thiazide or loop diuretics and gliptin therapy was associated with drug-associated bullous pemphigoid (p < 0.0001 for both). While compared with sitagliptin, exposure to linagliptin and vildagliptin were associated with bullous pemphigoid with an odds ratio of 5.68 and 6.61 (p < 0.0001 for both), respectively. These results suggest gliptins should be prescribed with caution to patients with type 2 diabetes with coexisting Alzheimer's and other dementias, or patients receiving long-term use of thiazides and loop diuretics. The use of sitagliptin over linagliptin and vildagliptin should be preferred in these patients.

RESUMEN

Human papillomavirus (HPV) is ubiquitously distributed in the population worldwide and its most frequent clinical presentation is cutaneous warts. Despite various treatment options currently available, many patients experience persistent and refractory disease. We sought to evaluate the clinical effectiveness and safety profile of intralesional HPV 9-valent vaccine for the treatment of recalcitrant warts. A retrospective study was performed for all cases of cutaneous warts treated with intralesional 9-valent HPV vaccine between January 2017 and March 2021. Epidemiologic, clinical, and treatment data, including safety and effectiveness scores, were reviewed. Our cohort was composed of 20 patients: 13 adults and seven children. Twelve patients (60%) displayed a complete response whereas 8 patients (40%) showed a partial response. Older age was associated with a better response to treatment, while a history of laser therapy was associated with a worse prognosis. Adverse events were local, transient, and negligible. No systemic adverse effects were reported. Intralesional 9-valent HPV vaccine may be considered for the treatment of recalcitrant cutaneous warts. Controlled studies are required to confirm these results.

RESUMEN

BACKGROUND: Psoriasis and psoriatic arthritis can present simultaneously or separately in children and may pose a diagnostic challenge. OBJECTIVE: To compare the dermatological manifestations in pediatric psoriatic patients with and without arthritis. METHODS: A retrospective case-control study of psoriatic patients ≤ 18 years old at Sheba Medical Center was conducted between 2011 and 2021. Patients with psoriatic arthritis versus psoriasis-only were compared according to body surface area (BSA) involvement, cutaneous distribution, severity of skin disease, response to treatment and related side effects. RESULTS: The study cohort included 29 psoriatic arthritis and 64 psoriasis-only patients matched by age and sex. The psoriasis-only group had a significantly higher mean BSA (19.7%, SD ± 18.7) than the psoriatic arthritis group (6.1%, SD ± 11.4), (p = 0.029). The skin distribution differed with the psoriasis group showing more involvement of the extremities, scalp, trunk, and genitals. Both groups primarily experienced partial responses to methotrexate, whereas the psoriasis group mainly saw complete responses to biologics. Adverse events were rare, with a higher incidence in the psoriasis group. CONCLUSION: This retrospective study highlights the differences in cutaneous disease characteristics, severity, and treatment response in pediatric patients with psoriasis and psoriatic arthritis, providing valuable insights for diagnosis and disease course in the pediatric population.

RESUMEN

Treating infantile hemangiomas with oral propranolol may be initiated in accordance with various protocols some require hospitalization. However, different adverse events have been reported during treatment, thus it is of special importance to find a protocol which is both safe and feasible. We performed a retrospective cohort study of all cases of infantile hemangiomas treated with oral propranolol at our institute between January 2010 and February 2020. Pretreatment evaluation consisted of pediatric cardiologist evaluation including electrocardiography and echocardiography. The propranolol starting dosage was 0.5 mg/kg bid; 2 weeks later the dosage was escalated to 1 mg/kg bid. During the initiation and escalation visits, heart rate and blood pressure were measured before and every hour for a total of 3 h, and blood glucose level was measured within the first hour of treatment. A total of 131 children were treated during the study period. Scalp, facial and genital region infantile hemangiomas were more prevalent in regard to their relative body surface area. No symptomatic bradycardia, hypotension, hypoglycemia, or any other adverse events were documented; few patients had asymptomatic bradycardia and hypotension, which were more common in infants below 6-months of age. Only one patient had asymptomatic hypoglycemia, not requiring any intervention. Initiation and escalation of propranolol treatment for infantile hemangiomas proved to be safe, and without symptomatic adverse effects. However, considering the young age of the patients and the possible asymptomatic adverse reactions, we recommend the following simple protocol as presented, for pretreatment evaluation and short monitoring during treatment initiation and dose escalation.

RESUMEN

BACKGROUND: Melasma is an acquired disorder of hyperpigmentation, affecting a million individuals worldwide. Energy-based devices (EBDs) employed to treat melasma include various types of lasers, intense pulsed light (IPL), and radiofrequency (RF). Recent studies have attempted to address recalcitrant and recurring melasma by combining energy-based devices with topical or oral medications. OBJECTIVE: This article reviews EBDs-based augmented treatment for melasma and suggests practical pathogenesis-oriented treatment regimens. Treatment algorithms are proposed to address various components of melasma. METHODS: A systematic PubMed search was conducted acquiring information from various studies on combination treatments of melasma involving EBDs. RESULTS: The 286 retrieved articles were filtered by title to contain at least one type of energy-based modality such as laser, IPL, or RF along with at least one other treatment method. Based on their subject matter, combinations were further categorized into the subheadings: laser plus medication, laser plus laser, and IPL- and RF-containing treatment methods. CONCLUSION: There are many energy-based combination treatments that have been explored for mitigation of melasma including laser therapy with medication, multi-laser therapies, IPL, RF, and microneedling devices. Melasma is an exceedingly difficult condition to treat, however, choosing the appropriate tailor-made treatment combination can improve the final outcome.

RESUMEN

BACKGROUND: Melasma is a complex and poorly understood disorder, with high rates of treatment failure and recurrences. OBJECTIVES: We aimed to review the current knowledge of the pathogenesis of melasma and apply this knowledge to clinical implications on relevant therapeutic interventions. METHODS: A systematic PubMed search was performed using the search term "((melasma[Text Word]) OR facial melanosis[Text Word]) AND (pathogenesis OR causality[MeSH Terms])" for articles published between 1990 and 2020. Included articles were then evaluated by two authors and assessed for relevant pathomechanistic pathways, after which they were divided into groups with minimal overlap. We then reviewed current treatment modalities for melasma and divided them according to the involved pathomechanistic pathway. RESULTS: A total of 309 search results were retrieved among which 76 relevant articles were identified and reviewed. Five main pathomechanisms observed in melasma were identified: (1) melanocyte inappropriate activation; (2) aggregation of melanin and melanosomes in dermis and epidermis; (3a) increased mast cell count and (3b) solar elastosis; (4) altered basement membrane; and (5) increased vascularization. Treatment modalities were then divided based on these five pathways and detailed in 6 relevant tables. CONCLUSION: The pathophysiology of melasma is multifactorial, resulting in treatment resistance and high recurrence rates. This wide variety of pathomechanisms should ideally be addressed separately in the treatment regimen in order to maximize results.

RESUMEN

BACKGROUND: The starch iodine test (SIT) is the gold-standard diagnostic tool for primary palmar hyperhidrosis (PPH). OBJECTIVE: This study aimed to evaluate the clinical effectiveness and safety profile of a novel approach for the detection of PPH by moisture response films (MRF) in comparison to the SIT. METHODS: This prospective comparative study of the 2 tests was conducted on 17 patients with PPH. Disease severity was evaluated by the SIT and the MRF methods during 4 sessions (twice before and twice after botulinum toxin [BTX] injections) on different days and by different investigators. The physician's global assessment (PGA) scoring of the comparable visual results was evaluated by 2 blinded independent dermatologists. The Hyperhidrosis Disease Severity Scale (HDSS) scores of the patients at baseline and after the BTX injections were correlated with the SIT and MRF results. RESULTS: The objective PGA scoring of the SIT results demonstrated poor correlation, whereas the objective PGA scoring of the MRF results correlated highly with the patients' HDSS scores both at baseline and after the BTX injections. CONCLUSION: Analysis of palmar hyperhidrosis by means of MRF was superior to SIT and was demonstrated to be more efficient, convenient, and accurate.

RESUMEN

Griseofulvin and terbinafine are considered effective first-line therapies for tinea capitis (TC). Haematological dyscrasias and hepatic injury are possible adverse effects with both drugs. There is a debate in the literature regarding the necessity of laboratory monitoring during griseofulvin and terbinafine treatment. We aimed at assessing the prevalence and severity of haematological and hepatic laboratory test abnormalities in a paediatric cohort of African immigrants in Tel-Aviv with TC who were treated with Terbinafine or Griseofulvin. We conducted a retrospective study of all TC cases diagnosed and treated at the paediatric dermatology clinic, Tel-Aviv Medical centre, between June 2013 and March 2019. Epidemiologic, clinical and laboratory data were collected. Our cohort included 321 patients of whom 225 (70%) were treated with Griseofulvin and 96 (30%) with Terbinafine. We identified a total of 64 (20%) patients with haematological or hepatic laboratory test abnormalities that in most cases (96.3%) were considered as mild. No difference in laboratory abnormalities prevalence was identified between the griseofulvin and terbinafine groups (21.3% and 16.6%, respectively). Only one patient treated with Griseofulvin revealed significantly increased levels of hepatic aminotransferases that required discontinuation of treatment. Mild elevation in hepatic transaminases is relatively common among paediatric patients treated with systemic antifungal treatment for TC. However, significant laboratory abnormalities are extremely rare and may be diagnosed and addressed early through periodic laboratory tests monitoring.

RESUMEN

BACKGROUND: Infantile hemangiomas (IHs) are the most common vascular tumors in children. In the past few years, topical beta-blockers (bBs) have been reported to be an effective treatment of superficial IHs. OBJECTIVE: We sought to evaluate the clinical effectiveness and safety profile of enhanced percutaneous delivery of bBs for the treatment of IH. METHODS: A retrospective study of all cases of IHs treated with enhanced percutaneous delivery of bBs between 2018 and 2019 was performed. Epidemiologic, clinical, and treatment data, including effectiveness score and safety, were reviewed. RESULTS: The study included 11 patients with a total of 11 IHs. Of the total number of IHs, 7 (63.7%) showed a good response to treatment and 4 (36.3%) had a partial response; thus all patients (100%) had good or partial response to treatment. No systemic or local adverse effects were reported. LIMITATIONS: This is an uncontrolled retrospective study. CONCLUSION: Enhanced percutaneous delivery of bBs is a safe and efficient topical therapy for IH.

RESUMEN

Successful treatment of Hailey-Hailey disease with intradermal botulinum toxin injections has been previously reported. The main disadvantages of this treatment are the excruciating pain and the risk of infections due to the numerous injections. We sought to evaluate the clinical effectiveness and safety profile of a novel approach using an energy-based device (Tixel, Novoxel, and Israel), followed by the topical application of botulinum toxin Type A for the treatment of Hailey-Hailey disease. A retrospective study of all cases of histologically diagnosed cases of Hailey-Hailey disease treated with Tixel device followed by topical application of botulinum toxin between 2018 and 2019 was performed. Epidemiologic, clinical, and treatment data, including effectiveness score and safety, were reviewed. The study included eight patients, of whom seven patients (87.5%) showed good or partial response. No systemic or local adverse effects were reported. There was no difference in effectivity between different body areas. Response to treatment ranged between patients with an average duration of 7.125 months after the second treatment. Tixel treatment followed by topical application of botulinum toxin can be considered in the treatment of Hailey-Hailey disease. This approach is less invasive, less painful, and yet effective as well as safe.

RESUMEN

PURPOSE: To investigate ocular manifestations in patients with vitiligo by multimodal imaging, including optical coherence tomography (OCT), color fundus photography, and fundus autofluorescence (FAF). METHODS: In this prospective, observational clinical study, vitiligo patients underwent ophthalmologic and dermatologic clinical assessment and imaging by spectral-domain OCT, FAF, and color fundus imaging. Ocular echography was performed as indicated. Statistical analysis was performed using paired T test and Pearson correlation. RESULTS: A total of 61 eyes of 31 vitiligo patients were examined. Ocular findings consisted of choroidal nevi (n = 10, 32%), of which four (40%) were bilateral; two patients (6.5%) had a prominent choroidal pattern, two (6.5%) had hypopigmentary retinal pigment epithelium (RPE) lesions, and one (3.2%) had peripapillary atrophy of the RPE. Choroidal nevi were demonstrated only in eyes of patients with generalized vitiligo and were more common with upper body involvement (p = 0.02) and more prevalent in women (p = 0.02). Hypopigmentary lesions were detected in two patients and demonstrated on OCT as RPE atrophy and as photoreceptor/RPE changes. CONCLUSIONS: In this case series, vitiligo patients had a higher rate of choroidal nevi than previously reported. The hypopigmentary vitiliginous fundus lesions were depicted on OCT as photoreceptor and RPE atrophy. These findings may suggest the advisability of regular ocular monitoring for vitiligo patients.
