Acute mesenteric ischemia (AMI) is a syndrome caused by inadequate blood flow through the mesenteric vessels, resulting in ischemia and eventual gangrene of the bowel wall. AMI may be classified as arterial or venous, non-occlusive or occlusive. The overall prevalence of AMI is 0.1% of all hospital admissions [1]. The exact prevalence of mesenteric venous ischemia (MVT) is not known, because many cases are presumed to be limited in symptomatology and to resolve spontaneously.
Introduction: We present the case of a 65 years- old woman who was admitted with a severe macrocytic anemia Hb= 5.7g/dl and diffuse bone pain. Biologically she has moderate thrombocytopenia 35 000/µl, a hepatic cytolysis and cholestatic syndrome. Material and method: The patient was extensively evaluated before presentation for a mild iron - deficiency anemia for which she underwent endoscopic examination of the upper and lower gastrointestinal tract- normal. The bone marrow aspiration on admission revealed a marked hyperplasia of the erythroblastic line with ~50% basophilic erythroblasts suggesting a regenerative erythroid hyperplasia. These changes along with the marked reticulocytosis on the peripheral blood smear oriented us towards a hemolytic anemia; Folic acid, vitamin B12, autoimmune tests and hemolytic tests were all normal. We continued the investigations with a thoraco-abdomino- pelvic computed tomography which identified diffuse demineralization, vertebral compactation and pelvic stress fractures. The breast examination revealed a right breast nodule, but the breast ultrasonography pleaded for benignity. Lacking a clear definitive diagnosis we decided to perform a bone marrow biopsy. Results: The osteo- medullary biopsy pointed towards a medullar invasion from a lobular mammary carcinoma; In these circumstances we performed an ultrasound guided biopsy of the right mammary lump thus histologically confirming a tumoral invasion of the bone marrow with subsequent anemia. The patient started chemotherapy in the Oncology ward. Conclusion: The particularity of this case consists in the pattern of anemia, which initially seemed iron deficient and afterwards macrocytic – apparently hemolytic and was actually due to the tumoral medullar invasion and also the nonspecific ultrasonographic appearance of the breast tumor.
Introduction: The infection caused by H. pylori appears secondary after a bacterial colonization of the stomach and the initial portion of the small bowel. H. pylori –infected patients can develop gastritis, peptic ulcer, stomach cancer or MALT lymphoma. H. pylori infection is defined by WHO like a type I carcinogen, its role in gastric carcinogenesis being supported by the greatest researchers. Objectives: In this study our purpose was to determine the endoscopic appearances in H. pylori infection quoted in medical literature until now and the frequency of their appearance in our group of interest. Materials and methods: In this study it was made an analytic study in which it was realized a retrospective cohort investigation at the Emergency Central Military and University Hospital “Dr. Carol Davila” Bucharest, gastroenterology branch –endoscopic department between 18.12.2012- 21.08.2013 on 1694 patients between 18 and 92 years old, with the medium age of 55 years old. As a diagnostic method for H. pylori infection we used superior digestive endoscopy during which were taken biopsies and it was made a fast urease test. Results: Regarding the variation of the endoscopic aspects at the population of study, we have found gastritis with all its aspects (which was Sidney classified) in the biggest percentage meaning 59.3% of the cases, followed with a percentage of 18.8% by those without any endoscopic abnormality, and then in 10,33% of the cases we have found peptic ulcer. With a smaller percentage, under 10%, we have found duodenitis at 8.67% of this patients, and finally the most severe lesions represented by gastric cancer and lymphoma were found at 2,7% of the H.pylori infected patients.
Background: Neuroendocrine tumors of the pancreas (NTP) comprise a unique and relatively rare group of tumors, of which gastrinoma and insulinoma are the most common types. Insulinomas tend to be small, solitary and benign, with surgical resection curable in most cases. Introduction: Insulinomas are localized preoperatively using conventional imaging studies as transabdominal ultrasonography (US), computed tomography (CT), and/or magnetic resonance imaging (MRI). Purpose: Endoscopic ultrasound (EUS) is a valuable tool in the diagnosis of insulinomas. Goals & methods: We performed a retrospective study on 21 patients with insulinoma (6 male and 15 female, 25 to 73 years of age), who were hospitalized and operated on between 2003 and 2012 at “Dr. Carol Davila” Central Military Emergency University Hospital, Bucharest. Results: US view was positive in 10% of patients (2 of 20), that presented proximal location. The sensitivity of CT was unsatisfactory, 21.05% (4 positive results of 19). CT failed to detect liver metastases, but identified nodal metastasis in one patient. MRI was performed in 18 patients and was diagnostic in 11 of them, recording a detection sensitivity of 61.11%, including infra- centimetric tumor size. EUS has a high resolution which allows detection of lesions with very small diameter is safe and minimally invasive. EUS was performed in all patients, being able to identify formations in 17, was inconclusive in 3, showing a diagnosis sensitivity of 81%. Liver metastases were demonstrated in 3 patients, one by US and all 3 by MRI. Conclusions: - CT with intravenous iodinated contrast agent had a poor sensitivity in detecting the primary tumors, was insensitive in detecting liver metastases, but showed metastases in lymph nodes. - MRI has higher sensitivity than CT in detecting primary tumors, including insulinomas with infracentimetric size, and is the imaging test of choice for possible liver metastases. - EUS is the preoperative imaging test of choice.
The burden of colorectal cancer (CRC) is increasing all over the world. The prevalence of diabetes mellitus is increasing. It is estimated that diabetes affects 387 million people worldwide. It is predicted that 552 million people worldwide will develop diabetes by 2030. A large pool of data indicate that DM increases by 2 fold the risk of CRC. This is the reason to firmly suggest the inclusion of DM in the criteria for CRC screening as an important measure to decrease the mortality of this ailment.
Chronic liver disease is a late stage of progressive hepatic fibrosis. It consists of functional and structural disruptions in most chronic liver diseases. An accurate diagnosis allows us to establish the degree of fibrosis and the stage of the disease, the prognosis of the patient and to predict a treatment response. Despite the fact that liver biopsy is considered a gold standard, non- invasive methods for diagnosing liver fibrosis have gained more and more importance. Whether we talk about serum biomarkers or imagistic methods from transient elastography to 3-D magnetic resonance elastography, the question remains: are these useful or useless? Serum biomarkers represent blood components that can reflect liver histological changes, thus they can monitor the continuous process of fibrosis. These can be subcategorized in direct (that show extracellular matrix turnover) and indirect markers (that reflect disturbances in the hepatic function). However these markers alone are not as accurate in the staging of fibrosis, only help differentiate patients without or with low grade of fibrosis from those with significant fibrosis and cannot be considered alone in the diagnosis of liver fibrosis. Imagistic methods include: ultrasound-based transient elastography, magnetic resonance elastography (MRE), 2D-shear wave elastography, acoustic radiation impulse imaging (ARFI) and cross sectional imaging, the first being the most used. Using a combination of non-invasive tools allows us to diminish the number of patients in need of liver biopsy. However, the patient must always be informed of the advantages and disadvantages of each method and its limitations.
