Metachronous gastrointestinal stromal tumor associated with other neoplasia - case presentation.

The association of gastrointestinal stromal tumor (GIST), synchronous or metachronous with other tumors is reported in special literature, the most frequent being associated with other gastrointestinal tumors. GISTs are the most common mesenchymal neoplasm of the gastro-intestinal tract with a malignant potential. We present a case of 68-year-old male patient diagnosed with GIST stage IV, unreachable due to liver metastases, treated with Imatinib, diagnosed at 13 months of prostate adenocarcinoma diagnosis [treated with hormonal therapy (HT) and external beam radiotherapy (EBRT)]; at 45 months from the first neoplasia diagnosis, the patient was diagnosed with the third neoplasia - lung squamous carcinoma - right inferior lobe, for which performed EBRT.

Xyloglucan for the Treatment of Acute Gastroenteritis in Children: Results of a Randomized, Controlled, Clinical Trial.

Background. Xyloglucan, a film-forming agent, improves intestinal mucosa resistance to pathologic damage. The efficacy, safety, and time of onset of the antidiarrheal effect of xyloglucan were assessed in children with acute gastroenteritis receiving oral rehydration solution (ORS).

Skin spiradenocarcinoma - case presentation.

Malignant eccrine spiradenoma is an extremely rare skin tumor of sweat gland origin. The available literature data indicates that spiradenocarcinoma nearly uniformly arises from a benign preexisting spiradenoma. Etiology is unknown but previous trauma is believed being an implicated factor.

AIDS-related lymphoma in a young HIV late presenter patient.

Non-Hodgkin's lymphoma (NHL) is an acquired immunodeficiency syndrome (AIDS)-indicative disease. Nowadays, NHL is rarely reported in Europe as indicative disease for human immunodeficiency virus (HIV) testing. We present the case of a 22-year-old Romanian male patient without past medical history, except the swelling of a submental lymph node 11 months ago.

Neoangiogenesis. Assessment in Esophageal Adenocarcinomas.

Esophageal cancer has always been subject of research for various studies. According to some authors, esophageal cancer represents the 10th leading cause of cancer in the world with a 5-year survival of 10 %. In terms of anatomopathological form of the esophageal neoplasia, the literature mainly describes two major pathological types: adenocarcinoma and esophageal squamous cell carcinoma.

Single arterial trunk arising from the aortic arch with aortic coarctation. Report of a case. Embryological considerations.

Abnormalities of the aortic arch occur mainly due to an abnormal development of the fourth aortic arch in the first 12 weeks of fetal life. These abnormalities may be asymptomatic for a long period, or can develop clinically when vascular rings surround the trachea and esophagus and cause tracheal and/or esophageal obstruction. We present the case of a full-term newborn baby, male.

Major omphalocele with liver protrusion. Liver dysmorphism. A case study.

In the Renaissance (1634), Ambroise Paré described for the first time the omphalocele, highlighting the serious prognosis of this malformation. The incidence of omphalocele varies between 1/2000-1/6000 births, both sexes being equally affected. We present the case of a male infant, born at term after a pregnancy that was not followed by the family doctor or by the specialist obstetrician and who died after five days.

Study of bone cells by confocal microscopy in fractures stimulated by ultrasound.

The ultrasound mechanism of action in fracture healing is still unknown. The mechanism that controls the compartment of each cell during healing process derives, possibly, from the microenvironment of said cells; studies in the field show differences of 55 to 84% between cross-sectional areas, depending on the sectioning mode. In order to assess the impact of ultrasound application to bone cells, we have examined bone tissue by help of Nikon E-600 microscope; the three-dimensional images have been obtained by Zeiss LSM 510 laser confocal microscope, from the Riken Physico-Chemical Analysis Laboratory, Japan.

Histomorphometric study regarding the evolution under treatment of the changes appearing at the level of the gingival mucosa in diabetic children.

The values of the glucose influence the status of the periodontium, but also the periodontitis influences the glucose balance by increasing the resistance to insulin. In the case of children in the first step the gingivitis appears, than if the glucose control is not made and the dental hygiene is defective the evolution is towards advanced periodontal disease. The present histomorphometric study wants to emphasize the eventual changes that appear at the level of the gingival epithelium before and after starting a correct treatment of the periodontal disease.

Comparative histomorphometric study of bone tissue synthesized after electric and ultrasound stimulation.

The clinical use of the alternative therapies in traumatology is conditioned by the knowledge and understanding of their actions on the bone tissue. The hereby study aims at the comparative assessment of the effectiveness of the direct current and ultrasounds in treating the fractures. Thus, we have proceeded to a comparative histological study of the bone tissue in the fractured area and the biomechanical description and the three-dimensional model of the stimulated bone's behavior by using micro-CT X-rays and the finite element analysis.

Investigation of ubiquitin deformation mechanism under induced stretch-compression loads.

Proteins folding and unfolding are conformational changes in the life of the proteins, which reveal the modifications in the organization of the molecules inside the chain. It is known that a very organized structure has great amount of entropy and tends to exchange the energy with the environment. The present work presents the results of the atomistic modeling using NAMD software released by the University of Illinois, USA, to reveal the hyper-elasticity under external loads and the progressive conformational shapes that are produced by the H-bonds breaking and recovering.
