Introduction: Surgery is commonly regarded as the mainstay of treatment of extramammary Paget disease (EMPD); however, nonsurgical approaches have gained popularity in recent years. Objectives: To review the published evidence for the efficacy and safety of nonsurgical modes of therapy for EMPD. Methods: A systematic review and meta-analysis of nonsurgical EMPD treatments was performed. The primary outcome was complete response (CR); secondary outcomes were clinical regression by ≥50%, adverse events, and recurrence rate. Results: The systematic review included 43 observational studies (341 patients; 7 prospective cohort studies, 19 retrospective cohort studies, and 17 cases series) evaluating 5 treatment modalities. Imiquimod (13 studies, 110 patients) administered at variable doses ranging from daily to twice weekly for 2-56 weeks demonstrated CR of 54% (95% CI, 40-67%; I 2 = 37%) and had a satisfactory safety profile. In 14 heterogeneous studies (122 patients) evaluating photodynamic therapy (PDT), only 36% (95% CI, 22-53%; I 2 = 52%) of patients achieved CR. Radiotherapy (12 studies, 67 patients) showed CR of 97%, but was associated with local and systemic side effects. Ablative lasers and topical fluorouracil and calcipotriene lacked adequate evidence of efficacy. Conclusions: Imiquimod and radiotherapy are the most appropriate nonsurgical modalities for EMPD treatment given their good efficacy and safety profile. PDT has limited efficacy but may be appropriate in selected clinical settings.
Verruca vulgaris (VV) is a prevalent skin condition caused by various subtypes of human papilloma virus (HPV). The most common causes of non-genital lesions are HPV types 2 and 4, and to a lesser extent types 1, 3, 26, 29, and 57. Although numerous therapeutic modalities exist, none is universally effective or without adverse events (AE). Pulsed dye laser (PDL) is a favorable option due to its observed efficacy and relatively low AE rate. However, it is not known which verrucae are most likely to respond to PDL, or whether the causative viral subtype influences this response. The objective of this prospective blinded study was to assess whether the HPV subtype was predictive of response to PDL. For that matter, 26 verrucae from 26 immunocompetent patients were biopsied prior to treatment by PDL. HPV coding sequences were isolated and genotyped using PCR analysis. Patients were treated by PDL (595 nm wavelength, 5 mm spot size, 1.5 ms pulse duration, 12 J/cm fluence) once a month for up to 6 months, and clinical response was assessed. Binary logistic regression analysis and linear logistic regression analysis were used in order to evaluate statistical significance. Different types of HPV were identified in 22 of 26 tissue samples. Response to treatment did not correlate with HPV type, age, or gender. As no association between HPV type and response to PDL therapy could be established, it is therefore equally effective for all HPV types and remains a favorable treatment option for all VV.
The purpose of this study is to assess the long-term efficacy of aged garlic extract to improve periodontitis. Two hundred and one participants were randomly stratified and assigned equally to the regimen group or the control group. At the start, 12 month, and 18 month subjects received dental examination and periodontal evaluation. Probing Pocket Depth and Gingival Recession were examined. For each efficacy parameter, the mean value of examination was calculated and assessed using paired-difference t tests. Statistical tests were two-sided using a 5% significance level. The mean value of pocket depth for the aged garlic extract group at 18 month was 1.06 ± 0.49 as compared to the baseline value of 1.89 ± 0.74 ( p <0.001) and the corresponding value of 1.50 ± 0.46 for the placebo group ( p <0.001), indicating the beneficial effect of aged garlic extract on periodontitis. According to a Multiple linear regression analysis the only three variables which reached statistical significance as predictors of PPD level were the baseline PPD scores ( p <0.001), smoking ( p = 0.020), and consumption of daily dose of aged garlic extract ( p <0.001). These results demonstrated that aged garlic extract is an effective supplement for preventing or improving periodontal disease. The well demonstrated benefits of aged garlic extract for the oral disease may also be used as a means to improve general health because of the close relationship between periodontitis and some systemic diseases such as diabetes, hypertension, atherosclerosis, and others.
Objectives To assess the effect of major salivary gland intraductal irrigations (IGs) to relieve mouth dryness. Methods We retrospectively analyzed the records of patients with mouth dryness who underwent major salivary gland IG during 2013–2015. Records included demographics, medical background, dry mouth etiologies and symptomatology, and results of sialometry and sialo‐cone‐beam computerized tomography. Subjective improvement following the IG procedure (yes/no) and sustained subjective improvement (mouth dryness relief for ≥1 month) were recorded. Objective improvement was assessed by comparing the mean unstimulated (USF) and stimulated (SSF) whole salivary flow (WSF) rate before and after the IG. Results Seventy‐four patients were included [mean age: 59.08 ± 12.46 years]. Improvement was detected in the USF (p = .027), but not in the SSF (p = .878). Fifty‐five (84.6%) noted subjective improvement, while 10 (15.4%) did not. Subjective improvement was positively associated with the USF following IG (p = .037), with salivary gland swelling episodes (p = .033), and with difficulties in swallowing dry foods (p = .014). Of those with subjective improvement, 45 (81.8%) reported sustained improvement, which was positively associated with lack of a gritty eye sensation (p = .042) and abnormal sialo‐CBCT findings (p = .001). Conclusions Major salivary gland IG is a simple and safe procedure that may relieve dry mouth for a relatively extended duration. Further studies are needed to confirm these preliminary findings and assess their underlying mechanisms.
Background. Solar urticaria (SU) is a rare photodermatosis causing a significant impact on patients' quality of life (QoL), and treatment is often challenging. Aim. To analyse clinical experience with a tailored stepwise therapeutic approach. Methods. A retrospective cohort design was used. Patients with suspected SU underwent laboratory investigations and photoprovocation. Those with a high minimal urticaria dose (MUD) were treated with a single antihistamine (protocol 1), and those with a lower MUD received three types of antihistamines (protocol 2); both protocols included a leucotriene receptor antagonist (LRA). In cases of failure, treatment was switched to omalizumab at doses of < 300 mg/month with incremental dosage increases as necessary (monthly dose range, 150-600 mg/month). Symptom relief and photoprovocation under treatment were evaluated. Results. In total, 30 patients (10 men, 20 women) were enrolled. Most (87%) were sensitive to visible light (1-70 J/cm 2 ) with or without extension to ultraviolet A. Of the 30 patients, 23 opted for our stepwise approach: 22 achieved complete remission on protocols 1 or 2 (n = 17) or after switching to omalizumab (n = 5), and another patient achieved partial remission under omalizumab. There were no treatmentrelated severe adverse effects. Conclusions. Symptoms of SU can be well controlled by treatment with antihistamines and an LRA tailored to the degree of photosensitivity, followed by omalizumab in refractory cases. This has important implications for patient QoL.
BackgroundFrom a dermatologist's perspective, there are four major types of cutaneous porphyrias (CPs): porphyria cutanea tarda (PCT), erythropoietic protoporphyria (EPP), variegate porphyria (VP) and hereditary coproporphyria (HCP). Scarce data are available regarding the epidemiology of CPs.ObjectivesTo describe the epidemiology of CPs in Israel, including distribution, incidence and prevalence rates of major types.MethodsThis retrospective study includes all patients who were diagnosed with CPs between the years 1988–2018. It is based on data from Israel's National Service for the Biochemical Diagnoses of Porphyrias, and Israeli patients’ nationwide electronic medical charts. Incidence and prevalence rates were calculated.ResultsOf 173 patients with CPs diagnosed during a 30‐year period, 65 (38%) had VP, 62 (36%) had PCT, 31 (18%) had HCP and 15 (9%) had EPP; with incidence rates of 0.29, 0.30, 0.17, 0.07, and prevalence rates of 6.3, 4.8, 2.9, 1.6, respectively, per million population. Characteristics of patients with PCT differed from those with other CPs with regard to lack of family history, older mean age at diagnosis [51 vs. 36 (VP), 35 (HCP) and 25 (EPP) years] and male predominance (81% vs. similar distribution). All patients with PCT were diagnosed at adulthood, while 20%, 19% and 15% of patients with VP, HCP and EPP, respectively, were diagnosed during childhood or adolescence.ConclusionsVariegate porphyria and PCT were found to be the most prevalent in Israel; however, CPs might be underdiagnosed, thus dermatologists’ awareness of these rare disorders is highly important.
