[en] Granular cells tumors are rare and asymptomatic lesions and by general, it is an incidental finding en high or low endoscopy. They were described for the first time by Abrikossoff in 1926. The more frequent locations are the buccal mucosa, dermis and subcutaneous cellular tissue, most of these tumors has a benign origin. This is the case of a woman aged 44 with a pyrosis history from a year ago; by high endoscopy it is noted a 8 mm lesion distal to esophagus and confirmed by histological study of granular cells tumor. Elective treatment of this lesion is the endoscopic polypectomy. Despite that the malign potential is low; we suggested a close clinical and endoscopic follow-up.

[en] The cytotoxic and cancerous action of bile acids on gastric mucosa is a very interesting subject within the gastroduodenal diseases due to they are able to alter the membrane, the cellular metabolism, to give rise to a inflammatory process, to increase the proliferation, the cell apoptosis and the DNA damage, that according to its intensity and persistence, favor the appearance of failures and mutations in cell replication. With the discovery and characterization of Helicobacter pylori it is considered that according to its intensity and the time of persistence in gastric mucosa provokes damages with failures and cellular mutations. In this sense, a prospective and descriptive study was conducted in the Institute of Gastroenterology in patients presenting with duodenogastric and high total bile acids to know the association between the intestinal metaplasia and the presence or not of Helicobacter pylori. Metaplasia was present in the 48.7 % of the 39 study patients, that there was a statistically significant association (p< 0.05) in Helicobacter pylori distribution in patients with and without intestinal metaplasia; that patients with duodenogastric reflux, despite of a histological lesion also had a greater frequency of negative results as regards the presence of Helicobacter pylori. In samples with histological diagnosis of severe and atrophic chronic gastritis, 75 %, respectively, had Helicobacter pylori and in consequence, there was a significant association between presence or not of microorganism and the chronic gastritis intensity. Intestinal metaplasia location was higher in antral region (84.3 %) and also with a higher ratio of microorganism positivity. In patients with duodenogastric reflux, presence of Helicobacter pylori don't seems to be associated with intense degrees of intestinal metaplasia, although the microorganism is present in all categories, but when there is not Helicobacter pylori, intestinal metaplasia to tend to develop in its less severe degrees. In all cases the Helicobacter pylori density was light

[en] Colorectal carcinoma is recognized as the second death cause from cancer in most of developed countries; the increasing exposure to risk factor such as smoking, changes in diet, in lifestyles, as well as environmental and infectious factors is conductive to its morbidity and mortality increase. A prospective and descriptive study was conducted in 65 patients older than 18 years seen from April, 2007 to April, 2008 in the Endoscopy Service of the National Institute of Gastroenterology, diagnosed with colorectal carcinoma by colonoscopy and histology. In collection form were registered: sex, age, personal backgrounds of colon cancer, polyps, intestinal inflammatory disease and cholecystectomy; family backgrounds of colon cancer or another location; toxic habits: smoking and alcoholism; diet as regards: vegetal fiber ingestion and animal fat; anatomic location of cancer and histology. We conclude that there was predominance of female sex, the more frequent diagnosis age was between 60 and 70 years. The personal background of colon polyp and the family background of colon cancer were the more frequent. There was also predominance of smokers and heavy drinkers with or without effect. There was a great ingestion of animal fat and few ingestion of vegetal fiber. The more frequent anatomical location was the rectosygmoid, where the histological colon adenocarcinoma had the greater frequency

[en] A study was conducted to assess the usefulness of multi-scan axial tomography techniques to detect, in a subclinical stage, the coronary damage in patients presenting with diabetes mellitus (DM) to describe the frequency of asymptomatic atherosclerotic affection and its potential association with the fasting and postprandial hyperglycemia. In study were included 59 patients with type 2 diabetes to compare the results of coronary calcium determination with the findings of angiography by multi-scan axial computed tomography (CAT-M). There was a concordance of a 44.1% between both studies, as well as a predominance of soft plaques in the 55.9 % of patients. The 42.4 % showed a narrowing of arterial lumen, which was significant in the 16.5 % of total. A high figure of patients with hyperglycemia had coronary damage compared to those ills with a good glycemia control (p = 0.024). This relation was more evident with the postprandial hyperglycemia (= 0.016). Hyperglycemia had a high opportunity (5.99 times) to detect coronary lesions by TAC-C compared to other major atherosclerosis risk factors like the high blood pressure, smoking, dyslipemias expressed in a significant way (p 0.045). We conclude that Angio TAC-C and Calcio Score techniques are useful to detect lesions of coronary arteries in patients with type 2 diabetes mellitus without symptoms of myocardial ischemia, which was associated to presence of a hyperglycemia, fundamentally postprandial

[en] The occurrence of nauseas and vomiting from chemotherapy are a significant complication. With appearance of antiserotoninergics 5HT3 (AR 5HT3) combined with steroids, have allowed a great control of these symptoms. The aim of present paper is to asses in a economic way two alternatives for antiemetic treatment in cancer

[en] Despite the progress achieved in the design of mechanical prosthetic valves, prosthetic valve thrombosis remains a frequent cause of morbidity, usually due to incorrect anticoagulation. A patient was presented with mitral prosthetic thrombosis one year after implantation, who had been diagnosed by transthoracic transesophageal echocardiography imaging and 64-slice computed tomography. Thrombolytic therapy was successful and led to the satisfactory evolution of the patient

[en] Carotid body tumors, paragangliomas or chemodectomas are uncommon neoplasms originating from paraganglion tissues, generally are benign, of slow growth and painless course, have a great vascular component in its structure. They may to show an aggressive locoregional behavior despite histologically haven't malignancy signs. Frequently are present in patients inhabit in high altitude regions. May to be sporadic or familial and occasionally are associated with paragangliomas in other sites. Present case was treated in our service, which demonstrates its local aggressive behavior

[en] Introduction: Autologous hematopoietic stem cell transplantation is a therapy used in certain situations to patients with Hodgkin's Lymphoma. Objective: To evaluate the influence of selected prognostic factors on the results of autologous hematopoietic stem cell transplantation in patients with Hodgkin's Lymphoma. Methods: A retrospective study of 57 patients with a diagnosis of Hodgkin Lymphoma transplanted at Hermanos Ameijeiras Clinical Surgical Hospital from 1991 to 2018 was carried out. The influence of several unfavorable factors was evaluated according to univariate and multivariate disease-free survival at five years. Results: A lower disease-free survival was found for all groups with unfavorable categories. Univariate analysis indicated that receiving three or more previous lines of treatment increased the probability of relapse on average 3.48 times. In the multiple evaluation, the probability of relapse was significantly increased by the existence of active disease at the time of transplantation (p = 0.023) and by not receiving radiotherapy in the conditioning treatment (p = 0.010). Conclusions: The importance of knowing the unfavorable factors was established. It was of noteworthy importance to avoid active disease at transplantation and to carry out a correct evaluation of risks and benefits regarding the possible inclusion of radiotherapy in the conditioning treatment.

[en] A 59 year-old male patient with a history of hypertension and regular consumption of sildenafil entered the service because of acute stroke and headache seizure. Physical examination detected left hemiplegia. By skull nuclear gadolinium magnetic resonance, an expansive lesion is observed which caught heterogeneously contrast. Possible diagnosis of high-grade brain glioma was raised. Right frontoparietal craniotomy was performed and a tumor lesion was not visualized. After ruling out the presence of high-grade glioma, the diagnosis of hemorrhagic venous infarction was assessed. CT angiography and clotting was made to rule out prothrombotic states to justify this disease entity. Special hematology studies were within normal values. The case was concluded as a venous sinus thrombosis associated with the use of sildenafil. (author)
