Abstract: Mesenteric adenitis consists of an important differential diagnosis of potentially serious diseases such as acute appendicitis, since they manifest themselves with a similar clinical picture. Case report: A 17-year-old male patient presented with periumbilical abdominal pain for 2 days, of abrupt onset and moderate intensity, who gave away with a common analgesic, which progressed to the right iliac fossa (RIF) and increased of intensity. He also reported liquid diarrhea, with several episodes a day, without mucus and/or blood, 38°C fever, anorexia and vomiting. He was hospitalized for investigating a possible diagnostic of Acute Appendicitis. In the exams, it was considered mesenteric adenitis, and antibiotic therapy was prescribed. The patient had complete improvement at the end of treatment. Conclusions: Given its importance as a differential diagnosis of numerous pathologies, as well as controversial before the therapeutic and diagnostic conduct, it is essential to report these cases in order to elucidate the specificities of this disease.

Abstract: Introduction: Splenic cysts are uncommon and usually do not generate signs and symptoms, being diagnosed by incidental findings. Case report: A 35-year-old, female patient attended the Luiz Gioseffi Jannuzzi School Hospital (HELGJ) presenting episodes of vomiting and abdominal pain in the left hypochondrium. She was hospitalized for diagnostic investigation. Computed tomography showed the splenic cyst. The procedure was the surgical approach by laparotomy with splenectomy. Histopathological confirmed the diagnosis. Discussion: Compared to the scarce reports in literature, the case described presented typical epidemiology and clinical features. Conclusions: Given the rarity of this pathology cases, it is essential to report these in order to elucidate the specificities and also to discuss diagnostic and therapeutic methods.

Abstract: Introduction: Gastrointestinal stromal tumor (GIST) occurrence is uncommon and usually manifested by nonspecific signs and symptoms, which hinders its reasoning as a diagnostic hypothesis. The objective is to report a case of female GIST with curative treatment through video-laparoscopy with partial gastrectomy. Case report: A 61-year-old female patient attended the Luiz Gioseffi Jannuzzi School Hospital (HELGJ) emergency room, with a sudden onset of upper gastrointestinal bleeding with hemodynamic instability. After stabilization, she was admitted for diagnostic investigation, showing sub-epithelial lesion of antrum in upper digestive endoscopy (UDE) and solid-cystic mass in the gastric antrum to computed tomography (CT). The conduct was the video laparoscopy surgical approach with partial gastrectomy. The histopathological and immunohistochemical aspects of the surgical specimen showed a gastrointestinal stromal tumor (GIST) in a gastric antrum of low grade of malignancy, positive e-Kit and mycotic index (50 cga) < 5. Discussion: Compared to the scarce reports in literature, the case described presented typical epidemiology, but the clinical picture was not the most incident. Conclusions: Given the rarity of this pathology cases, it is essential to report these in order to elucidate the specificities and also to discuss diagnostic and therapeutic methods.

Abstract: the visual recognition of body parts activates somato-motor representations in the brain. in the present study, we investigate the influence of the plane in which hand drawings are displayed (vertical or horizontal) on mental rotations evoked by a handedness recognition task. sixteen right-handed volunteers participated in an experiment where the task was to evaluate the handedness of drawings of the human hand presented in different perspectives and orientations while the manual reaction time (mrt) was measured. for eight volunteers, the hand drawings were displayed on a vertical screen monitor, while for the remainder a mirror was employed and the same drawings appeared on the horizontal plan. our main finding was that there are no differences in mrts among the drawings displayed vertically or horizontally, with some exceptions. however, the mrts were longer when the hands in the drawings assumed configurations that were more awkward to perform using real movements. these results show that the implicit movements involved with handedness recognition are mainly dependent on biomechanical constraints for distal (hand), but not proximal (shoulder) movements.

Abstract: Introduction: Syphilis consists in a systemic infect contagious pathology with a chronic character. The etiological agent consists of an anaerobic spirochete bacterium, Treponema pallidum. Laboratory diagnosis can be made through a direct investigation of the etiologic agent or non-treponemal (VDRL) and treponemal (FTA-Abs) serological tests. False-negative results are rare. Objectives: The present report presents a rare case of a man with a secondary syphilis syndrome who was initially undiagnosed due to the prozone effect, since he presented VDRL in low titers, and was later confirmed with a new diluted serum sample and VDRL and FTA-Abs, which were positive. Conclusion: A close look should be given to patients who, although the clinical condition is compatible, complementary exams may not be, and clinical cases should be carefully evaluated so that the patient is not treated late.

Abstract: Silicon is a beneficial element that can mitigate abiotic stresses, such as ammonium toxicity. The objective herein was to evaluate the effects of silicon (Si) on mitigating toxicity caused by excess ammonium in maize plants grown in nutrient solution. An experiment was conducted with maize plants (cultivar DKB 390 VT Pro II) grown in a greenhouse in pots (8 L) in a hydroponic system. The treatments were arranged in a 2 × 2 factorial, consisting of two ammonium concentrations (30 and 60 mmol·L-1) in the absence and presence of Si (10 mmol·L-1), arranged in a completely randomized design with six repetitions. At 28 days after applying the treatments the dry mass of shoots and roots was evaluated, along with accumulation of silicon and nitrogen in the shoots. The use of silicon resulted in increases in the studied variables, regardless of ammonium concentrations. Silicon reduced the effect of toxicity caused by ammonium excess in maize plants, resulting in greater growth and dry matter accumulation.
