1. Intestinal Microbiome, Small Intestinal Bacterial Overgrowth and Inflammatory Bowel Diseases - What are the Connections?

M. ANDREI, T. NICOLAIE, ADRIANA STOICESCU, ADRIANA TEIUSANU, S. GOLOGAN, M. DICULESCU

IBD (inflammatory bowel diseases) represent chronic idiopathic inflammatory diseases, prone to relapse in the digestive tract; it is estimated that they result from the interaction of the intestinal microbiome with the intestinal immune system. The inflammatory microbiome exerts multiple beneficial roles. Perhaps the central element to developing IBD is dysbiosis; there is still an incompletely established association between intestinal microbiome changes in patients with IBD and SIBO (small intestinal bacterial overgrowth). Influencing the intestinal microbiome may play an adjuvant therapeutic role in the treatment of IBD. We present a synthesis of the connections between the entities mentioned above.

C.D. USCATU1,2 , T. DUMITRESCU3,4 , IONELA CRISTINA DELIU5 , ALEXANDRA DUMITRESCU6 , M. SCHENKER7 , F. MIXICH1

Purpose: This study aims to determinate the microvessel density at the base of the tumor, as well in tumor’s mass, in order to determinate the number of neovascularization vessels (marked with CD105) in comparison with presence or absence of autophagy puncta. Material/Methods: Standard immunohistochemistry was performed on 38 samples of colorectal adenocarcinoma, in order to determinate the presence of autophagy and neovascularization blood vessels with the help of LC3, CD34, CD31 and CD105 antibodies. Results: The autophagy process was observed in the cancerous cells and was noted as present in both regions of interest from the tumor. The mean number of blood vessels market with CD105 is higher in tumor mass then at its base, p value of the Student t test being highly significant (p<0.0001). Conclusions: The presence of autophagy puncta was notice in every case, both in the mass of the tumor and at its base. Microvascular density of new-grown blood vessels is higher in the mass o

3. The Estrogen-Induced Effects on Myometrium Are the Result of Activation of Two Different Receptor Types: GPER and Erα

OANA SORINA TICA, A. COMANESCU, MARIA BOGDAN, D.O. ALEXANDRU, A.A. TICA, T. CIUREA

GPER (G protein coupled estrogen receptor 1), a particular estrogen binding site, is ubiquitously present in human tissues, but its precise physiological role is still very disputed. GPER is associated with normal and abnormal estrogen-dependent proliferations in female tissues and is involved in generation of rapid estrogenic answers. A very important fact is that GPER-induced genomic effects are additive to those mediated by “classic” estrogen receptors, but regarding the rapid effects, as we prove in this study, these can be significant different or even antagonistic.

A. DEMETRIAN, A. DOBRINESCU, SERENADA BALA, CAMELIA DEMETRIAN, IOANA ANDREEA GHEONEA, DANA MARIA ALBULESCU

Transthoracic needle biopsy (TNB) is a fast and safe method used to establish definitive diagnosis for most thoracic lesions, whether the lesion is located in the pleura, the lung parenchyma, or the mediastinum. Diffuse disease and solitary lesions are equally approachable.TNB can avoid (when technically possible) more complex diagnostic interventions such asmediastinoscopy, thoracoscopy and exploratory thoracotomy. This article focuses on the advantages of TNB which is a safe, affordable and quick method to obtain histopathological confirmation of intrathoracic tumors. Material and MethodsThe study included a total of 235 cases over a period of 4 and a half years (01.01.2011-30.04.2015). We investigated the demographic and clinical parameters, the guiding methods, the histological results and the complications of the procedure. ResultsThe median age of the patients was 62 years and the predominent sex was male. We could obtain a tissue biopsy in 99% with a histopathological confirmati

ELENA TATIANA CARTANA, CLAUDIA GEORGESCU, DIANA TUDORASCU, C.C. VERE, A. SAFTOIU

We report the case of a patient presenting in the Gastroenterology Department with intermittent rectal bleeding during the past year. A diagnosis of a low rectal adenocarcinoma was based on colonoscopy examination with biopsies, and staging procedures included transrectal endoscopic ultrasonography and magnetic resonance imaging of the abdomen and pelvis (cT2N0M0). Consequently the patient was referred for pre-operative chemoradiotherapy, achieving a complete clinical response as documented by repeated EUS and MRI examinations. Transanal endoscopic microsurgery with pathological assessment of the resected specimen revealed residual adenocarcinoma, highlighting the limitations of current imaging methods, and the constant need of technological improvements.

12. The Role of Real Time Elastography in the Diagnosis of a Patient with Liver Cirrhosis and Carcinoma of the Uncinate Process of the Pancreas - Case Study

DANIELA LARISA SANDULESCU, S.C. DINESCU, IOANA ANDREEA GHEONEA, SINETA CRISTINA FIRULESCU, S. SANDULESCU

Hepatic cirrhosis represents the most advanced stage of any chronic liver disease characterized by progressive fibrosis. We report the case of a patient with carcinoma of the uncinate process of the pancreas and an occult form of liver cirrhosis. We concluded, based on the bioclinical profile, that the jaundice syndrome had an underlying mixed mechanism, obstructive and hepatic. Although, the clinical suspicion of pancreatic cancer was backed up by ultrasound, computed tomography and magnetic resonance imaging, we did not obtain, through these imaging investigations, any indicative features of liver cirrhosis. In order to further evaluate the presence of liver cirrhosis, we assessed liver stiffness using two non-invasive methods: Transient Elastography and Real Time Tissue Elastography (RTE). We observed highly suggestive features of liver cirrhosis only through RTE, although its diagnostic accuracy still needs large validation studies. Intraoperative assessment confirmed the diagnosis

13. Overlap Syndrome-Systemic Sclerosis, Systemic Lupus Erythematosus and Dermatomyositis - Case Report

CLAUDIA CIRSTEA, ANDREEA BARBULESCU, LOREDANA ELENA STOICA, F.A. VREJU, PAULINA CIUREA

Overlap syndrome is often defined as an entity that satisfies the classification criteria for at least two distinct connective tissue disease. We present the case of a female patient, 39 years old, hospitalized in the Dermatology clinic of Emergency County Hospital in september 2014, for ulcerative lesions on the left hallux and the second and third left toes, associated with pain and difficulties in walking. After performing the clinical exam and paraclinical tests, we decided for both intravenous synthetic analogue of prostacyclin PGI2-iloprost and local therapeutic measures, with a favourable outcome of the ulcerations. Due to the fact that overlap syndrome is an entity with several visceral involvement and unpredictable evolution, we must not disregard the skin manifestation, so that we can prevent a severe evolution and improve the outcome. The case represents a permanent challenge for the multidisciplinary team that examine, survey and periodically adjust the treatment, based on

ANTONIA BLENDEA, DIANA MONICA GEORGESCU, STEFANA OANA PURCARU, DANIELA ELISE TACHE, I. FLOREA, LOREDANA ELENA STOICA, I. TOLEA, CLAUDIA VALENTINA GEORGESCU

The purpose of this study was the clinical and histo-immunohistochemical analysis of two cases: a cutaneous pigmented facial malignant melanoma and a lumbar congenital nevus with malignant transformation. A series of clinical elements raised the suspicion of some malignant melanocytic lesions and the histopathological analysis through the paraffin embedding technique confirmed the clinical suspicion. The immunohistochemical analysis using the streptavidin-biotin-peroxydase method of the facial malignant melanoma showed: S100 protein intense and diffuse positive, Tyrosinase diffuse positive, HMB45 strong and focal positive, Cyclin D1 positive in approximately 40% and Ki-67 positive in almost 70% of the tumor cells. The malignant melanoma developed on the nevocellular nevus displayed: S100 protein intense and diffuse positive, both in the nevus cells and in the malignant melanocytes as well, Tyrosinase intense and diffuse positive in the malignant melanocytes, poor and focal positive in

15. A Case Presentation Emphasizing the Value of Full-field ERG in Retinal Dystrophies

ANDREEA C. CORICI, D.O. ALEXANDRU, OANA M. CORICI, MARIA IANCAU

Purpose: A case presentation is used to discuss the value of full-field ERG in the diagnosis of cone-rod dystrophy. Case report: A 49 year old female patient known with amblyopia and myopic astigmatism since childhood, visited us complaining of decreased visual acuity and photophobia. Her BCVA was 0.6 in the RE and 0.4 in the LE. The fundus examination revealed normal colored and sharply limited papilla, normal macula and narrower vascularization. The Ishihara test was 10/15 in both eyes. The fundus autofluorescence and optical coherence tomography were normal. The DA 3 ERG was decreased and slightly delayed as well as the DA 0.01 ERG. Regarding the cone response, the LA 3.0 and 30 Hz flicker ERG were markedly reduced and delayed. The ERG findings indicated cone-rod dystrophy. At the 8 years follow-up examination, the BCVA decreased to 0.4 and 0.2 in the right and left eye, respectively, the Ishihara test was 1/15 in both eyes and the fundus examination showed a macula with no reflex,

16. Imaging Evaluation of the Orbit in Graves Ophthalmopathy

T.N. SAS, GEORGIANA-CRISTIANA CAMEN, A. STEFANESCU, IOANA ANDREEA GHEONEA

Diagnosis of Graves ophthalmopathy is based on the typical eye signs and symptoms, the exclusion of other orbital pathologies and evidence of thyroid autoimmunity. We report the case of a non-smoker 61 years old woman, known with Graves disease, which performed a 3T MRI examination in order to evaluate the orbits. The MRI exam revealed eye protrusion, increased orbital fat with compression on the optic nerve and increased volume of the extraocular muscles. We concluded that MRI, using high-field 3T imaging techniques, is very important for diagnosis of these anomalies, making the differential diagnosis with other pathology and also providing additional information in the decision for therapy.
