BACKGROUND: Tinea capitis is a term used to refer to dermatophyte lesions on the scalp, that occur mainly in children, immunodeficient patients or older adults. They can be dry or inflammatory (kerion Celsi) and can be generated by agents such as Trichophyton tonsurans, Microsporum canis, M. gypseum and T. mentagrophytes. Although its treatment is simple, it can leave alopecia if it is not treated. CLINICAL CASES: We report the cases of two children from Nicoya, Guanacaste and Golfito, Puntarenas, Costa Rica, who were diagnosed as kerion Celsi and tinea capitis by T. mentagrophytes. CONCLUSIONS: T. mentagrophytes is a zoophilic fungus capable of generating kerion Celsi because it has antigens that arouse an exacerbated immune response on the host. [ABSTRACT FROM AUTHOR]

Physalis peruviana L. is native to the Andes and its fruit is consumed fresh for its vitamin content and medicinal properties. The growth of the plants of this species is heterogeneous, as it has limited genetic improvement because it is a wild species. Physical and chemical mutagens applied to seeds or organs for propagation can generate new varieties with changes in morphology, yield, adaptability and resistance. The objective of this research was to determine the effect of seed irradiation on the fruit quality characteristics of M1 plants of Physalis peruviana L., and the hypothesis was that at least one dose of irradiation on M1 plants of uchuva (cape gooseberry) favorably modifies the fruit quality characteristics. The study was conducted in a greenhouse with UVII-720 plastic cover, from August 2015 to February 2016. The treatments were 14 doses of gamma 60Co (0 to 275 Gy) and the experimental design was completely randomized with six replicates. The radiation reduced the weight of the fruit with calyx from 3 to 32% and the weight without calyx from 3 to 29%. Fruit sweetness was reduced at doses greater than 100 Gy, with the exception of 200 Gy; in contrast, firmness increased from 1 to 9% at the 100 and 75 Gy doses. Fruit size and shelf life were not affected. Seed irradiation with 60Co gamma rays negatively alters the weight and some variables of the fruit quality of P. peruviana mutant plants.

BACKGROUND: Systemic sclerosis is characterized by thickening of the skin and systemic involvement, which affects the musculoskeletal, renal, pulmonary, cardiac and gastrointestinal systems, with fibrotic and/or vascular complications. The UVA-1 phototherapy has opened the way as a therapeutic alternative for the treatment of the skin in the systemic sclerosis, since it achieves a deeper penetration in the dermis and a decrease in fibrosis. CLINICAL CASES: Four female patients with systemic sclerosis were treated with UVA-1 phototherapy. The average age was 53 years. They were administered between 40 to 50 sessions, divided into 3 to 4 sessions per week at a dose of progressive increase between 10 and 40 J/cm2. In the 4 patients, relief of cutaneous sclerosis was achieved, evidenced by greater flexibility of the skin, improvement in oral opening and general decrease in fibrosis. CONCLUSIONS: UVA-1 phototherapy in low doses is useful in the control of the progression of sclerosis in skin and contributes to improve pain and cutaneous pruritus. There are necessary to perform controlled studies and the use of clinimetric methods to define the scope and effectiveness of UVA-1 phototherapy in patients with systemic sclerosis.

A systematic review of the literature on the studies published between 2000 and 2017 that evaluate the quality of life related to health status in patients with cutaneous lymphoma was performed, including the analysis of the different scales used to measure it. Consulted databases such as PubMED, Clinical Key and Scopus were included as well as bibliographic references from key articles. The following MeSH terms were used during the review: "lymphoma", "quality of life", "lymphoma, Tcell, cutaneous", "skin neoplasms". Original observational, descriptive and analytical studies were considered. The quality of the report of the articles was evaluated using the STROBE checklist, in addition with the PRISMA declaration, with the purpose of fitting the methodology to the guidelines for the accomplishment and publication of systematic reviews. From the reviewed bibliography, nine articles showed in greater detail aspects related to the quality of life in patients with cutaneous lymphoma, which used specific and generic measurement scales or surveys with domains focused on the assessment of the emotional, functional and/or symptomatic commitment. Few articles in the literature assess quality of life in patients with cutaneous lymphoma. We consider that its importance has been underestimated, despite the repercussions that this disease may have on the emotional well-being and the social role of patients and their caregivers.

Golden berry (Physalis peruviana L.) is an indeterminate habit plant, during its vegetative growth nitrogen is the nutrient most demanded and usually absorbs it as nitrate. A combination of NH4+ y NO3– , where NH4+ is lower than or equal to 50 % of total nitrogen increases plant growth, only under certain circumstances and this beneficial effect varies across cultivars, but the response to ammonium in golden berry is not known. Therefore, the objective of this study was to evaluate the morphologic response, fruit yield and quality of Physalis peruviana L. plants in two year-old plants, (re-sprout) and in new plants derived from seed, to the joint application of NH4+ and NO3– . Experiments were carried out in a greenhouse with a completely randomized design and treatments of the first experiment were the result of combining the ratio NH4+/NO3– (0: 100, 25:75 and 50:50), and sprout vigor (low, medium and high). In a second experiment new plants derived from seeds were used and with the same ratios NH4+/NO3– used in the first experiment. Results were analyzed using ANOVA and treatment means were compared with the Tukey’s test (p≤0.05). In re-sprouting plants, the highest values of final height and stem diameter were obtained in plants with high vigor and with the application of 25 % of NH4+ (p≤0.05), whereas the highest yield was obtained in plants with high and medium vigor, and with 50 and 25 % of NH4+ (p≤0.05). Neither NH4+/NO3– ratio in the nutrient solution nor the vigor of the re-sprouts affected the concentration of soluble solids or shelf life of the fruits. In plants from seeds there was also not effect of the NH4+/NO3– ratio on plant height, but with 50 % of NH4+ the diameter of stem increased. The higher yields were obtained in plants treated with the ratio 50/50, and the concentration of soluble solids in fruits did not show a clear effect on the ratio NH4+/NO3– , although at 119 d after transplanting the greatest value in fruits of plants treated only with nitrate (0/100) (p≤0.05) was reached. Thus, the combined application of ammonium and nitrate increases yield but reduces soluble solids in fruit and shelf life and vigor of re-sprouts is neither determinant nor consistent on yield.

BACKGROUND: Vitiligo is a depigmenting disorder of autoimmune origin that has a possible relationship with vitamin D since it increases melanogenesis and tyrosinase content in melanocytes. OBJECTIVE: To determine the association between vitamin D levels in patients with vitiligo that attend phototherapy in the University IPS and the baseline clinical severity. MATERIAL AND METHOD: An analytical cross-sectional study was done from June 2016 to February 2018. The serum vitamin D levels of patients older than 18 years were evaluated and the clinical severity was measured according to the affected body surface with the VES tool (Vitiligo extent score), before starting the phototherapy treatment. RESULTS: Seventy-one patients were evaluated with vitiligo (mean age: 47.6 years) with median duration of the disease of 60 months. The insufficiency and deficiency of vitamin D was found in 22 (31.1%) and 23 (32.3%) patients, respectively; 36.6% had levels of 25 (OH)D3 ≥ 30 ng/mL. The median in the VES score was 2.6%, and the median value of the vitamin D was 26.6 ng/mL. When correlating vitamin D levels with the VES score, no association was shown. CONCLUSIONS: There was no association between vitamin D levels and the extent of the affected body surface. [ABSTRACT FROM AUTHOR]
