Abstract: Darier disease (DD), also known as follicular keratosis, is a rare autosomal dominant hereditary acantholytic dermatosis caused by a mutation in the ATP2A2 gene. Skin lesions are characterized by persistent confluent papules, preferentially located on the seborrheic areas of the face, chest and back. The hands, feet and nails are also commonly affected. DD has a chronic course with frequent relapses. Their treatment is often difficult and unsatisfactory. We present the case of a 54-year-old male with a history of keratotic papules with a brownish-black color, with a foul-smelling, pruritic and ardent appearance on the back and trunk, since the age of 19, which worsen in the summer. His 27-year-old daughter has a similar picture with her skin lesions started at age of 17 in the region below the breast, back, trunk, feet and hands. After the skin biopsy, the diagnosis was confirmed and acitretin 30 mg/day was instituted. The importance of this case report is to alert health professionals that the diagnosis of DD should be considered in family members of patients, especially those in the first degree, and also in patients with follicular keratolytic dermatoses, being an important differential diagnosis of this group of patients diseases.

Abstract: The cultivation of cotton is a relevant socioeconomic activity in the Brazilian agricultural scenario. In the Brazilian Northeast, however, production is limited by low rainfall, requiring water supplementation, a problem for the cotton cultivation practiced in the semi-arid region, due to the presence of saline ions in several water sources, from where the water is used for irrigation. It is necessary to identify cultivars that better tolerate saline stress in order to provide subsidies for their cultivation under such conditions. In this sense, the objective was to evaluate the tolerance of cotton cultivars to salinity. The experiment was conducted in a greenhouse, belonging to the Natural Resource Technology Center of the Federal University of Campina Grande, Campus I, Campina Grande, Brazil, in a completely randomized design in a 2 × 5 factorial scheme, with four replications, totaling 40 experimental units (BRS 368 RF and BRS SAFIRA) submitted to five saline levels (1.5, 3.0, 4.5, 6.0 and 7.5 dS·mˉ1). Irrigation with water saline of EC from 1.5 dS·mˉ1 affects adversely the growth of cotton cultivars, causing reductions in plant height, stem diameter, leaf area and number of leaves. Saline stress reduced the levels of the photosynthetic pigments of the cotton plants studied.

Abstract: aim: constructed wetlands (cws) have shown to be an efficient way for removing nutrients from wastewaters. however, a negative effect is the emission of greenhouse gases (ghgs). methane (ch4) is a ghg released from the organic matter degradation under anaerobic conditions by methanogenic bacteria. in cws, the excessive nutrient inputs may stimulate both primary production and methanogenesis and then affect the overall cost-benefit balance of this system. here, we assessed the role of cattail stands (typha domingensis pers) on ch4 concentrations in eutrophic and mesotrophic constructed wetlands. methods: cws were filled with water and sediment colonized by the aquatic macrophyte typha domingensis pers from two tropical freshwater lakes, one mesotrophic and another eutrophic. results: our results showed consistently higher ch4 concentrations in waters and sediment in the eutrophic cws than in the mesotrophic cws (two times), indicating a positive influence of eutrophication on methanogenesis. conclusion: in conclusion, ch4 emissions from tropical cws demand to be considered or even mitigated in any use of this system.

Abstract: Paragangliomas are rare tumours with a prevalence of 1/10000 to 1/30000. Tumors arising from the paraganglia are characteristically of low malignant potential. Vertebral metastases are exceedingly rare, and only isolated case reports have described them. The authors present the clinical course of a 47 years-old female patient with a familial paraganglioma [PGL] with vertebral metastastization, who underwent an intralesional tumor excision and corpectomy. Genetic screening demonstrated a new germinal frameshift mutation of the SDHB exon 6 [c.587-591DelC]. After surgery there was normalization of the analytical parameters and imagiologic screening. One year later she presented a new image in the the pedicle of T11 on the contralateral side of the surgical incision. She performed 2 treatments with MIBG and 1 cicle of radiotherapy that made the new lesion regress. Currently the patient does not present any clinical or analytical evidence of new metastasis. This case outlines the clinical course of a patient with a PGL syndrome for whom a rare vertebral metastasis was diagnosed. It highlights the importance of identifying patients with germline SDHB mutations, as these patients are at a high risk of developing malignant disease.
