Abstract	Dermatofibrosarcoma protuberans is an uncommon neoplasm that is most often seen in young adults. The most common clinical presentation is the protruding form; however, other subtypes are known, such as the atrophic. In 2012 there were only 33 reports of this variant in the literature. Many cases of Dermatofibrosarcoma protuberans in children are only discovered in adulthood because they were not diagnosed early. Due the high morbidity, we raise the need for attention from the dermatologist to recognize uncommon neoplasms in the clinical practice. We report a case of a 15-year-old patient diagnosed with atrophic Dermatofibrosarcoma protuberans on the back.

Abstract	The tropical forest carbon sink is known to be drought sensitive, but it is unclear which forests are the most vulnerable to extreme events. Forests with hotter and drier baseline conditions may be protected by prior adaptation, or more vulnerable because they operate closer to physiological limits. Here we report that forests in drier South American climates experienced the greatest impacts of the 2015–2016 El Niño, indicating greater vulnerability to extreme temperatures and drought. The long-term, ground-measured tree-by-tree responses of 123 forest plots across tropical South America show that the biomass carbon sink ceased during the event with carbon balance becoming indistinguishable from zero (−0.02 ± 0.37 Mg C ha−1 per year). However, intact tropical South American forests overall were no more sensitive to the extreme 2015–2016 El Niño than to previous less intense events, remaining a key defence against climate change as long as they are protected.

Abstract	Aim: Water availability is the major driver of tropical forest structure and dynamics. Most research has focused on the impacts of climatic water availability, whereas remarkably little is known about the influence of water table depth and excess soil water on forest processes. Nevertheless, given that plants take up water from the soil, the impacts of climatic water supply on plants are likely to be modulated by soil water conditions. Location: Lowland Amazonian forests. Time period: 1971–2019. Methods: We used 344 long-term inventory plots distributed across Amazonia to analyse the effects of long-term climatic and edaphic water supply on forest functioning. We modelled forest structure and dynamics as a function of climatic, soil-water and edaphic properties. Results: Water supplied by both precipitation and groundwater affects forest structure and dynamics, but in different ways. Forests with a shallow water table (depth <5 m) had 18% less above-ground woody productivity and 23% less biomass stock than forests with a deep water table. Forests in drier climates (maximum cumulative water deficit < −160 mm) had 21% less productivity and 24% less biomass than those in wetter climates. Productivity was affected by the interaction between climatic water deficit and water table depth. On average, in drier climates the forests with a shallow water table had lower productivity than those with a deep water table, with this difference decreasing within wet climates, where lower productivity was confined to a very shallow water table. Main conclusions: We show that the two extremes of water availability (excess and deficit) both reduce productivity in Amazon upland (terra-firme) forests. Biomass and productivity across Amazonia respond not simply to regional climate, but rather to its interaction with water table conditions, exhibiting high local differentiation. Our study disentangles the relative contribution of those factors, helping to improve understanding of the functioning of tropical ecosystems and how ...

Abstract	Purpose: Doxorubicin (DOX) is a chemotherapeutic that is widely used for the treatment of many human tumors. However, the development of cardiotoxicity has limited its use. The aim of the present study was to evaluate the possible efficacy of mito-TEMPO (mito-T) as a protective agent against DOX-induced cardiotoxicity in mice. Methods: C57BL/6 mice were treated twice with mito-T at low (5 mg/kg body weight) or high (20 mg/kg body weight) dose and once with DOX (24 mg/kg body weight) or saline (0.1 mL/20 g body weight) by means of intraperitoneal injections. The levels of malondialdehyde (MLDA), a marker of lipid peroxidation, and serum levels of creatine kinase were evaluated 48 h after the injection of DOX. Results: DOX induced lipid peroxidation in heart mitochondria (p < 0.001), and DOX-treated mice receiving mito-T at low dose had levels of MLDA significantly lower than the mice that received only DOX (p < 0.01). Furthermore, administration of mito-T alone did not cause any significant changes from control values. Additionally, DOX-treated mice treated with mito-T at high dose showed decrease in serum levels of total CK compared to mice treated with DOX alone (p < 0.05). Conclusion: Our results indicate that mito-T protects mice against DOX-induced cardiotoxicity.

Abstract	Introduction: aggressive angiomyxoma is a highly aggressive, rare neoplasm of the mesenchymal tissue with a high recurrence rate. It represents an important differential diagnosis of pelvic tumors in women of reproductive age. This study aims to describe a case of aggressive angiomyxoma. Case report: woman, 37 years old, complained about a bulge on the right perianal region, and anal itching and burning, bleeding, tenesmus and incontinence. The proctologic examination confirmed the perianal bulge and extrinsic compression of the posterior wall of the rectum. Computed tomography (CT) of the pelvis showed a well-defined pelvic mass extending to the right rectal area. Exploratory laparotomy showed a mass of fibro elastic consistency adjacent to the pelvic organs and closely attached to the distal rectum, and performed a resection of the pelvic tumor afterward. Anatomopathological analysis revealed an aggressive angiomyxoma. Magnetic resonance imaging (MRI) of the pelvis showed signs of recurrence in the pelvic cavity on the right side of the rectum. A surgical procedure was performed to resect the lesion. After an asymptomatic period, the MRI showed solid growths located in the right ischiorectal fossa. A new surgical procedure identified only retention cysts in the pelvis and right ischiorectal fossa, only lysis of adhesions was performed. The patient is currently undergoing follow-up without disease recurrence.

Abstract	INTRODUCTION: Ulcerative colitis (UC) is a chronic inflammatory disease that affects the rectum and colon, involving periods of exacerbation and remission. A considerable number of patients requires surgery during the course of this disease. OBJECTIVE: The purpose of this study is to analyze the profile and therapeutic approach of patients with UC. METHODS: This is a retrospective study that analyzed medical records of patients diagnosed with UC between 1999 and 2010. We selected 45 patients and analyzed the following variables: age, gender, ethnic group, interval between onset of symptoms and diagnosis, extraintestinal manifestations, extent of colonic involvement, disease complications, pharmacological treatment, indication for surgery, time between diagnosis and indication, surgical procedures, early and late complications and pathological results of surgical specimens. Data were analyzed descriptively and compared with other studies. RESULTS: The clinical profile of the patients was consistent with the literature. Nine patients underwent surgical treatment: seven were submitted to proctocolectomy with anastomosis in the ileo-anal pouch and two were submitted to total colectomy; in addition, eight were submitted to ileostomy. Postoperative complications occurred in 55.5% of patients. CONCLUSIONS: The study confirms data from the literature regarding the profile and therapeutic approach of patients with ulcerative colitis. INTRODUÇÃO: A retocolite ulcerativa (RCU) é uma doença inflamatória crônica que acomete reto e cólon, cursando com períodos de exacerbação e remissão. Uma parcela considerável de pacientes necessita de procedimento cirúrgico ao longo do curso dessa enfermidade. OBJETIVO: Este estudo objetiva analisar perfil e abordagem terapêutica de portadores de RCU. MÉTODOS: Trata-se de estudo retrospectivo realizado por meio da análise de prontuários de pacientes acompanhados com diagnóstico de RCU no período de 1999 a 2010. Foram selecionados 45 pessoas, sendo analisadas as variáveis: idade, sexo, raça, intervalo entre início dos sintomas e diagnóstico, sintomatologia, manifestações extraintestinais, extensão do acometimento colônico, complicações da doença, tratamento medicamentoso, indicação de cirurgia, tempo entre esta e o diagnóstico, procedimentos cirúrgicos, complicações precoces e tardias e resultado anatomopatológico das peças cirúrgicas. Os dados foram analisados de forma descritiva e comparados com outros estudos. RESULTADOS: O perfil clínico dos pacientes foi condizente com a literatura. Nove foram submetidos a tratamento cirúrgico, sendo realizadas sete proctocolectomias com anastomose em bolsa íleo-anal e duas colectomias totais, além de oito ileostomias. As complicações pós-operatórias ocorreram em 55,5% dos pacientes. CONCLUSÕES: O estudo corrobora com os dados da literatura referentes ao perfil e abordagem terapêutica dos pacientes com diagnóstico de RCU.
