The current study aims to do a comparative analysis of the results obtained with two End-Member(EM)grain-size modeling techniques(Analy Size and Bas EMMA) and the Environmental Sensitive Grain-Size(ESGS) modeling for sediment samples collected in the mudbelts of the southern Brazilian shelf. The methods were compared using grain-size data from the south Brazilian shelf, and the results are discussed here. It is the first time that the concept of ESGS, in its present form, is utilized outside China. The results show that despite its relative ease of use, the ESGS is not fully comparable to the EM analyses, and only two grain-size ESGS classes were recognized as analogous to EMs. The comparison of the Analy Size and Bas EMMA procedures also revealed significant differences between the techniques. A comparative analysis between the two EM techniques revealed advantages in the Bas EMMA, especially in the better correlation of the end-members with the original grain size distribution. The analysis of the geographical distribution of the EM abundances allowed point sources of sandy populations to be recognized as well as the contribution of the Rio de la Plata as a source of silty sediments to be inferred.

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) 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.

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.

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.
