RESUMEN
BACKGROUND: Narrowband ultraviolet B phototherapy (nbUVB) is a well-established, well-tolerated and efficacious treatment for eczema. There is a distinct lack of literature surrounding the therapeutic use of nbUVB in eczema in children and especially in children with higher skin phototypes (III to VI). METHODS: We undertook a retrospective review of children aged 18 years and under with eczema who had undergone nbUVB in our department between 1 January 2011 and 31 December 2017. Abstracted data included sex, age, skin phototype, severity as graded by a paediatric dermatologist, cumulative dose, response to treatment and subsequent remission. RESULTS: In total, 60 children had nbUVB. Of those, 56 had more than 10 nbUVB exposures. Complete or near-complete clearance was achieved in 31 children (52%). Of those, 24 (77%) had a skin phototype of III or greater. Clinical remission rates of these patients were 100%, 87%, 57% and 52% at 0, 3, 6 and 12 months, respectively. Seventeen patients (28%) suffered side effects. Most commonly these were mild side effects such as erythema and xerosis. CONCLUSION: We have demonstrated that nbUVB is a safe, well-tolerated and efficacious form of treatment for children with atopic eczema. We have shown it to be effective in those with skin phototypes greater than III and shown that they are a group that may derive greater long-term efficacy. In clinical practice, preference for nbUVB as second-line treatment, over oral systemics, should always be considered.

BACKGROUND: In 2008, Ninewells Hospital became the first centre in the UK to offer grenz rays as a treatment for inflammatory dermatoses. Since then, 122 courses have been administered for the following conditions; scalp psoriasis (n = 36), nail dystrophies (n = 27), hyperkeratotic eczema/psoriasis (n = 22), palmoplantar pustulosis (n = 9), perianal pruritus (n = 9), warts (n = 4) and other conditions (n = 15). AIM: To review all patients who received grenz rays in order to determine which conditions have been treated successfully and to estimate remission times. METHOD: Patient notes were reviewed, and follow-up was supplemented by subsequent dermatology clinic letters and telephone consultation. RESULTS: For scalp psoriasis, clearance was achieved with 13 courses, marked improvement with 19, minimal improvement in 3 and no change with 1. Treatment of palmoplantar psoriasis/hyperkeratotic eczema showed clearance with 7 courses, marked improvement with 9, minimal change with 2 and no change with 4. Of the courses for nail dystrophies (mainly psoriasis), clearance occurred with 1, marked improvement with 7, minimal change with 8 and no change with 11. In addition to immediate outcomes, the remission times were also evaluated. For scalp psoriasis, only 8 of the initial 32 patients still had clearance or marked improvement at the most recent follow-up. For nail dystrophy, 3 of 8 patients remained in remission, while for hyperkeratotic eczema/psoriasis, 7 of the initial 16 patients who had clearance or marked improvement had sustained this improvement, and only 1 patient with palmoplantar pustulosis still had clearance at the most recent follow-up. CONCLUSIONS: Grenz ray therapy is an effective treatment for some chronic inflammatory skin conditions that are resistant to routine therapies. The period of remission for scalp psoriasis was good for some patients but disappointingly short for others. Future studies involving different cumulative doses with subsets of different dose fractionations may help optimize treatment regimens.

BACKGROUND: There is only retrospective evidence for the efficacy of narrowband ultraviolet B (NB-UVB) in children with eczema. OBJECTIVES: To measure the difference in means for objective scores [Six Area Six Sign Atopic Dermatitis score (SASSAD), percentage surface area] and quality-of-life scores, between patients treated with NB-UVB and unexposed cohorts at the end of treatment, and 3 and 6 months post-treatment. METHODS: Twenty-nine children aged 3-16 years for whom NB-UVB was indicated, were scored prospectively using SASSAD and percentage surface area involvement at baseline, at 12 weeks (end of treatment) and 3 and 6 months post-NB-UVB. Their scores were compared with those of unexposed children (n = 26) for whom NB-UVB phototherapy was indicated and offered, but who chose not to undertake treatment. RESULTS: There was a 61% reduction in mean SASSAD score in the NB-UVB cohort compared with an increase of 6% in the unexposed cohort. Mean SASSAD score for the NB-UVB cohort at the end of treatment was 11.6 vs. 24.8 for the unexposed; difference in means -13.2 [95% confidence interval (CI) -18.7 to -7.7, P < 0.0001]. Mean surface area involvement at the end of treatment was 11% for the NB-UVB cohort vs. 36% for the unexposed cohort; difference in means -25% (95% CI -34% to -16%, P < 0.0001). Subjective and quality-of-life scores showed significant difference between cohorts at the end of treatment (P < 0.05). Objective scores remained significantly lower than in the unexposed cohort 3 and 6 months after treatment. CONCLUSION: NB-UVB is clinically effective and improves quality of life in children with moderate-to-severe eczema. The effect is maintained for 6 months after treatment.

Eczematid-like purpura of Doucas and Kapetanakis is a type of pigmented purpuric dermatoses (PPDs) with eczematous changes in the purpuric surface. A 10-year-old male and a 44-year-old male patients were admitted to our clinics for itching and flaking of the skin rashes. Based on the clinical and histopathological evaluations, the rashes were identified as eczematid-like PPDs of Doucas and Kapetanakis. Both patients were treated with narrow band ultraviolet B. The lesions were remarkably regressed following the treatment. These cases reported due its rarity and good response to narrow band ultraviolet B.

Treatment of hand eczema is dominated by the administration of topical glucocorticosteriods. If topical treatment fails, the best second-line option is ultraviolet (UV) therapy alone or as combination therapy. UVB and PUVA (psoralen plus UVA) therapy is effective and has relatively few side effects. Due to the localized nature of the disease, topical PUVA therapy is preferable to systemic PUVA treatment. Among the topical methods, cream PUVA therapy is simple, safe and highly effective. Recent clinical studies have demonstrated the therapeutic efficacy of a new retinoid called alitretinoin, a 9-cis-retinoic acid. However, even this form of treatment does not lead to a complete cure in all patients. Under the primacy of multimodal treatment, UV therapy should be administered as combination therapy if oral retinoids are not sufficiently effective.

Objective: To investigate the clinical effects of combined utilization of narrow-spectrum medium-wave ultraviolet, red light, and low power He-Ne laser on treatment of post-burn eczema. Methods: From July 2014 to July 2017, 80 patients with post-burn eczema who met the study inclusion criteria were treated in our burn rehabilitation center, and their clinical data were analyzed retrospectively. Patients were divided into ultraviolet treatment group, red light treatment group, laser treatment group, and combination treatment group according to the utilized treatment methods, with 20 cases in each group. Patients in ultraviolet treatment group were treated with narrow-spectrum medium-wave ultraviolet once every other day for 10 minutes each time. Patients in red light treatment group and laser treatment group were treated with red-light and low power He-Ne laser respectively once a day for 10 minutes each time. Patients in combination treatment group were treated with combination of the above three methods without sequence or interval time, and the treatment time and interval time were the same as the previously described. All patients were treated for four weeks since the time of admission. The itching degree, surface area of the affected body, degree of keratosis, and degree of cracking of target tissue were evaluated using Eczema Area and Severity Index (EASI) scoring method after each treatment. Eczema improvement rate was calculated according to the total score of EASI to determine the curative effect. The therapeutic effective time was recorded. The therapeutic effective rate was calculated according to the total scores of EASI before treatment for the first time and 4 weeks after treatment. Besides, the adverse reactions of patients were also observed and recorded. Data were analyzed by Chi-square test, Kruskal-Wallis rank sum test, Wilcoxon signed rank sum test, one-way analysis of variance, Least Significant Difference-t test, and Bonferroni correction. Results: Therapeutic effective times of eczema of patients in ultraviolet treatment group, red light treatment group, and laser treatment group were similar, respectively (13.7±1.3), (16.4±1.6), and (15.1±1.7) d (t=0.32, 0.58, 0.74, P>0.05). The therapeutic effective time of combination treatment group was (6.3±0.9) d, significantly shorter than that of ultraviolet treatment group, red light treatment group, or laser treatment group (t=5.62, 4.72, 4.61, P<0.05 or P<0.01). Compared with those before treatment for the first time, eczema itching degree, surface area of affected body, degree of keratosis, degree of cracking, and total score of EASI of patients in ultraviolet treatment group, red light treatment group, laser treatment group, and combination treatment group showed obvious improvement in 4 weeks after treatment (Z=5.372, 4.392, 4.284, 3.998, 4.092, 3.904, 4.042, 4.216, 3.684, 3.890, 5.081, 4.794, 4.094, 3.493, 3.995, 5.084, 4.903, 4.384, 3.995, 4.063, P<0.05 or P<0.01). Each item score and total score of EASI of eczema of patients in the first three groups were close (P>0.05), while each item score and total score of EASI of eczema of patients in combination treatment group was significantly better than those of ultraviolet treatment group, red light treatment group, and laser treatment group (H=2.482, 2.491, 3.583, 3.462, 6.025, 2.492, 3.693, 3.085, 3.482, 6.042, 5.831, 5.831, 4.893, 4.092, 6.931, P<0.05). Therapeutic effective rates of eczema of patients in ultraviolet treatment group, red light treatment group, and laser treatment group were close, respectively 60%, 60%, and 55% (χ(2)=1.46, 1.63, 0.97, P>0.05). The therapeutic effective rate of eczema of patients in combination treatment group was 90%, significantly higher than that of ultraviolet treatment group, red light treatment group, or laser treatment group (χ(2)=3.43, 4.15, 2.97, P<0.05 or P<0.01). There were no serious adverse reactions appeared in patients of all the four groups after treatment. Three patients in ultraviolet treatment group had local skin erythema, which was alleviated after symptomatic treatment. Conclusions: Combination of narrow-spectrum medium-wave ultraviolet, red light, and low power He-Ne laser in treating post-burn eczema is superior to single therapy in terms of clinical effective time and efficacy, which has no obvious adverse reaction and is worthy of promotion.

BACKGROUND: Chronic hand and foot eczema (CHFE), a prevalent debilitating disorder affecting approximately 15% of the population, presents a socioeconomic and psychosocial burden for patients and often follows a chronic course, refractory to conventional therapies. Thus, a large need exists for more effective therapeutics; the excimer laser (308 nm) is effective for some inflammatory skin diseases, but its efficacy has not been evaluated for CHFE. METHODS: The study is a retrospective chart review conducted on 30 patients with recalcitrant CHFE (19 with hand involvement, four with foot involvement, and seven with both) treated twice weekly with excimer laser (308 nm) single wavelength ultraviolet (UV)B radiation between January 2013 and December 2014. RESULTS: Improvements in clinical scores included a 69% reduction in average physician's global assessment (PGA) scores (from 2.77 at baseline to 0.87 after treatment, P < 0.0001) with a parallel reduction in average modified total lesion/symptom scores of 70% (from 10.2 to 3.1, P < 0.0001). Only mild sunburn-like reactions were observed. CONCLUSION: This report evaluates excimer laser for patients with refractory CHFE and shows excellent and sustained efficacy for this treatment. Compared to other UV therapies, excimer laser offers lower cumulative doses of UV radiation by targeting specific areas. This effective treatment should be considered alone or in combination with other established or newer therapies.

BACKGROUND: Sebaceous cell carcinoma is a distinctive tumor of the eyelid associated with a high rate of metastasis and mortality. Involvement of both upper and lower lids has been described; however, involvement of all 4 eyelids is extremely rare. OBJECTIVE: To describe the evaluation and diagnosis of the clinicopathologic features in a 74-year-old patient with 4-eyelid sebaceous carcinoma and a history of whole face irradiation for eczema. METHODS: Bilateral eyelid, conjunctiva, map, and fine needle biopsy of enlarged, submandibular lymph node specimens were stained with hematoxylin-eosin and oil-red-O for light microscopy and fresh-frozen sections were evaluated by electron microscopy. RESULTS: The biopsy specimens from the eyelids and conjunctiva showed sebaceous carcinoma cells in the meibomian glands and scattered within the conjunctival epithelium. The cells were moderately well differentiated. Similar cells stained with oil-red-O were found in the submandibular lymph nodes. CONCLUSIONS: The appearance of bilateral sebaceous carcinoma supports the concept of simultaneous occurrence of multiple primaries in specific patients, especially after radiation therapy. Patients with a history of facial irradiation and atypical eyelid lesions should be evaluated for malignant tumors such as sebaceous carcinoma.

A patient with the nevoid basal cell carcinoma syndrome had been treated with radiation therapy to the hands at 5 years of age. Multiple basal cell carcinomas of the palms and dorsa of the hands developed when the patient was 28 years of age. It is proposed that the radiation therapy induced tumors in palmar pits that seem to represent a forme fruste of basal cell carcinoma. Radiation therapy should be avoided in individuals with the nevoid basal cell carcinoma syndrome.

INTRODUCTION: Chronic graft versus host disease (GVHD) has rarely been reported in children. Optimal treatment should minimize infectious complications and preserve the child's growth. We report a case of cutaneous GVHD in a two year-old boy, who presented an eczema-like eruption and responded well to broad band UV-B therapy. CASE REPORT: A two year-old boy with acute myeloblastic leukemia had a heterologous bone marrow transplantation with a graft issued from an unrelated female donor. Three month later, he developed eczema-like lesions of the trunk, arms and legs associated with diffuse alopecia, despite oral corticosteroids and cyclosporine treatment. Histologic findings were consistent with GVHD. Topical corticosteroids and broad band UV-B therapy were initiated, while oral corticosteroids and cyclosporine doses were tappered off. GVHD lesions cleared, allowing withdrawal of oral corticosteroids and cyclosporine 3 and 12 months respectively after initiation of UV-B therapy. No relapse occurred 24 months after systemic treatment discontinuation and 12 months after broad band UV-B therapy was stopped. CONCLUSION: This observation suggests that broad band UV-B therapy is an effective treatment for eczema-like, cutaneous GVHD.

Dubowitz Syndrome is an autosomal recessive disorder with a unique set of clinical features including microcephaly and susceptibility to tumor formation. Although more than 140 cases of Dubowitz syndrome have been reported since 1965, the genetic defects of this disease has not been identified. In this study, we systematically analyzed the DNA damage response and repair capability of fibroblasts established from a Dubowitz Syndrome patient. Dubowitz syndrome fibroblasts are hypersensitive to ionizing radiation, bleomycin, and doxorubicin. However, they have relatively normal sensitivities to mitomycin-C, cisplatin, and camptothecin. Dubowitz syndrome fibroblasts also have normal DNA damage signaling and cell cycle checkpoint activations after DNA damage. These data implicate a defect in repair of DNA double strand break (DSB) likely due to defective non-homologous end joining (NHEJ). We further sequenced several genes involved in NHEJ, and identified a pair of novel compound mutations in the DNA Ligase IV gene. Furthermore, expression of wild type DNA ligase IV completely complement the DNA repair defects in Dubowitz syndrome fibroblasts, suggesting that the DNA ligase IV mutation is solely responsible for the DNA repair defects. These data suggests that at least subset of Dubowitz syndrome can be attributed to DNA ligase IV mutations.

Grenz ray therapy has declined in the United States during the past several decades with respect to availability, use, and resident training. However, it remains a simple, affordable, and effective option for managing several refractory dermatoses, especially psoriasis, hand eczema, and allergic contact dermatitis. Though high-dose grenz irradiation has been associated with the development of nonmelanoma skin cancers, grenz ray therapy is considered a safe treatment modality when administered according to the guidelines recommended herein. We review the value of grenz irradiation in contemporary dermatology.

Dermatologic radiotherapy is based on the standard physical and radiobiological parameters. The radiation quality most often used in dermatology lies between 10 and 50 kV. Another important parameter is the half-value depth which should correspond to the depth of the tumor below the skin surface. In this way the skin is not over-exposed to radiation treatment. Indications for radiotherapy of malignant skin tumors include basal cell carcinoma, squamous cell carcinoma, severe actinic keratoses, lentigo maligna, lentigo maligna melanoma, Merkel cell carcinoma, and Kaposi sarcoma, as well as T- and B-cell lymphomas. Most patients with malignant skin tumors require life-long monitoring after radiotherapy. The most common benign lesions where radiotherapy may be indicated are eczemas, psoriasis, and keloids, but its use should be carefully weighed in these settings.
