Tumor location was: stomach four, duodenum one, small bowel seven, and colon three. Pathological examination set the main criteria for assessing the risk of recurrence and indication for adjuvant therapy: the tumor size, the histological type spindle cell nine, cancer benign tumour four, and mixed two and the mitosis rate, while the immunohistochemistry examination established the correct diagnosis positivity for CD and CD34 and criteria of aggressiveness positivity for Ki All cases were operated, the surgical procedure being chosen according to the tumor location and stage.
The therapeutic outcome was: a postoperative morbidity rate of Conclusions: GIST has been imposed over the last decade as the main type of non-epithelial tumor of the digestive tract. The preoperative imagistic investigations can be very useful for setting the surgical strategy. The diagnostic value of immunohistochemistry and silver impregnation techniques for characterization of normal, reactive and tumoral astrocytes Alina Simona Sovrea, Cancer benign tumour Bianca Bosca, Carmen Georgiu, Anne-Marie Constantin, Mohamed Amine Ben Abdalah, Dan Gheban Astrocytes represent a heterogeneous population of specialized glial cells responsible not only for accomplishing various important functions in the healthy nervous tissue, but also for reacting to all types of the central nervous system diseases and trauma.
GFAP immunostaining is considered to be the most accurate of the routine techniques used for identifying astrocytes; however, silver impregnation techniques, which are inexpensive and approachable, might be a reliable alternative.
The present research has brought into question cancer benign tumour tried to assess the sensitivity and specificity of these classical methods for identifying and differentiating normal and reactive from tumoral astrocytes. Our study included 10 supratentorial gliomas specimens of various grade and two normal brain samples.
We performed a histological study on consecutive seriated sections labeled using four methods: the immunostaining for GFAP glial fibrillary acidic protein and the cancer benign tumour silver impregnation techniques: Ramon y Cajal, Bielschowsky-Cajal and Gomori.
For each tumoral case, two areas were examined: the tumoral parenchyma and the tumor borders considered as reactive gliosis and were both compared to healthy brain parenchyma; for each area, three microscopic fields were assessed and two parameters were recorded: a semi-quantitative score the astrocytes density and a qualitative score the color intensity.
We used a complex statistical analysis in order cancer benign tumour process the data and to compare the diagnostic value of silver impregnation techniques versus GFAP immunostaining the reference method in terms of tumoral grading and differentiating tumoral from normal and reactive astrocytes.
Our results indicated that there data provided by both GFAP immunostaining and silver impregnation techniques were comparable. The role of NO in the pathogenesis of chronic viral hepatitis is not fully cancer benign tumour but it seems that its overproduction is responsible for the pathological changes under inflammatory conditions. Aim: In this paper, we analyzed the correlation between immunohistochemical expression of iNOS and liver fibrosis in tratamentul parazitului de bandă la om viral hepatitis.
Materials and Methods: Liver cancer benign tumour from patients diagnosed with chronic viral hepatitis B and C were embedded in paraffin and further used for histological staining and immunohistochemical reactions to detect the expression of iNOS and TGF-beta1. The degree of liver fibrosis cancer benign tumour established using special staining trichromic Masson and Gomori s silver impregnation. Results: In samples with low degree of fibrosis, we observed a discrete positivity for iNOS in periportal hepatocytes and the immunohistochemical reaction for TGF-beta1 were limited to the endothelial cells of liver sinusoids and pro-inflammatory cells from the portal tracts.
Positive reaction for TGF-beta1 increased with the degree of liver fibrosis, while the expression of iNOS was enhanced in hepatocytes, as well as in bile ducts and endothelial cells. Conclusions: Infection with hepatitis B and C viruses induces iNOS expression in hepatocytes, suggesting that NO overproduction might have an important role in progression of chronic viral hepatitis to cirrhosis. These data represent preliminary study on the impact on silica nano-networks in targeted delivery and controlled cancer benign tumour of antitumor drugs and they may be efficiently used for future biomedical applications in cancer therapy.
Corresponding author: Alexandru Mihai Grumezescu, Chem. Materials and Methods: The studied material consisted of lymph node LN tissue samples obtained by biopsy or surgical excision from patients histopathologically diagnosed with tuberculosis.
For confirming the diagnosis, Ziehl-Neelsen staining was carried out and, in some cases, PCR technique was used. Results: Patients were mainly women, with a mean age of 35 years. Also, multiple LN group involvement was present in only five cases. The most affected LN groups were: the lateral cervical, submandibular, axillary, inguinal, supraclavicular and mesenteric.

In paired LN groups, there was no predilection for any of the body sides. Necrosis was present in almost all cases, displaying the whole range of cancer benign tumour features, but usually the acidophilic, microgranular one. Fibrosis was rarely encountered. The extension of TB process was not a rare event. Conclusions: LNs seem to be the favorite location of TB besides the lung.
The overall morphological picture revealed an active and destructive profile of the bacillary aggression in the LN parenchyma, which could mean either a higher sensitivity of the LN tissue or a more vulnerable background of the patients schistosomiasis eggs TBLN lesions.
The characterization of stem cell in this type of carcinoma could determine the appearance of new ideas concerning origin and evolution. There is an impressive amount of data in the literature related to TNBC cancer benign tumour a growing interest for stem cell research during the past years, but there are no data concerning the genetic characterization of cancer benign tumour cells in the context of cell biology of TNBC as compared with associated DCIS.
We performed immunohistochemical studies for the expression and distribution of several stem cell-related antigens, focusing on the association of TNBC with DCIS and comparing the presence of stem cells cancer benign tumour the invasive and in the in situ component. Optimization of detection, identification and characterization of tumorigenic breast cancer stem cells might permit further identification of targeted treatment.

Interleukin 8 IL-8 is an important proinflammatory cytokine with an important role in leukocyte chemoattraction. IL-8 also represents an important tumorigenic and proangiogenic factor.
From these patients, we have prelevated two types of samples: serum and tumor fragment. Results: IL-8 values were significantly increased, both in serum and tumor supernatant. The highest IL-8 values were found in tumor supernatant and in advanced stages; IL-8 increased values were correlated with tumor growth and TNM stage. Conclusions: IL-8 has an important role in colorectal cancer growth and metastasis and represents an important therapeutic target in this type of cancer.
IL-8 represents also a predictor for colorectal cancer prognosis. Anatomical cancer benign tumour histological considerations of placenta vascular diseases with implications in forensic medicine Roxana Folescu, Andrei Gheorghe Marius Motoc, Carmen Lacramioara Zamfir, Adrian Cosmin Ilie Placenta, as a highly specialized organ in connecting the maternal and fetal organism, is frequently affected by a specific vascular pathology.

The correlation between the macroscopic and the microscopic aspects cancer benign tumour the fetal placenta vascularization together with the appearance of fibrin deposits is used to determine the pathological cause of death.
Different studies suggest the hypothesis of precocious development of fibrin deposits during pregnancy, due to some immune-like reactions or due to the circulatory variations in the villous territory. The present research was realized on placentas - out of placentas collected in the past 10 years, were from term births, 98 from premature births and 82 cancer benign tumour abortions. The fibrin deposits in the placenta resulting from abortion can also be interpreted as alterations caused by the same circulatory variable conditions.
In the therapeutic abortion, the placental fragments do not contain fibrin deposits. The study assesses the macroscopic and microscopic aspects of the vascular pathology at the placental level in cases with medical and legal implications.

In many cases, the laparoscopy had an exclusive diagnostic purpose, of whose success has been primarily responsible the targeted biopsy. Current issues are discussed, centered on the most advanced technologies used in minimally invasive approach of pediatric malignancies, referring to the effect of minimizing the possible complications that can arise from this type of intervention. The authors concluded that laparoscopic technique is the method of choice in comparison to other ways of biopsy classical surgery, ultrasound cancer benign tumour, tomography, etc.
Published19 Jan Abstract The noninvasive diagnosis of the malignant tumors is an important issue in research nowadays. Our purpose is to elaborate computerized, texture-based methods for performing computer-aided characterization and automatic diagnosis of these tumors, using only the information from ultrasound images. In this paper, we considered some of the most frequent abdominal malignant tumors: the hepatocellular carcinoma and the colonic tumors.
Tonsillar hypertrophy implications in sleep disorders in adults and children Reka Solyom, Iren Csiszer, Adriana Neagos Introduction: The obstructive sleep apnea syndrome is the most common sleep disorder. It covers a multitude cancer benign tumour symptoms associated with apnea.
Next to polysomnography, otorhinolaryngological clinical examination plays an important role in establishing the diagnosis, in evaluating any oropharyngeal and hypopharyngeal modification. Patients and Methods: In this research, we intend to demonstrate the histopathological examination importance in establishing the tonsillar hypertrophy degree. This is made in direct correlation with its volume, and the sleep apnea degree. In this context, we have conducted a retrospective study between cancer benign tumour a group of 69 patients diagnosed by polysomnography with Obstructive Sleep Apnea OSA.
In the research, otorhinolaryngological examination was supplemented with histopathological examination of the parts collected after the surgery.

Results: It has been demonstrated that the size, volume of the tonsil can be directly correlated with the severity of sleep apnea. The term tonsil hypertrophy is a histopathological one, with or without macroscopic implications. A specificity of tonsil enlargement without the narrowing of the oropharyngeal isthmus was demonstrated. This was in all groups of obstructive apnea, even in snoring patients with normal apnea-hypopnea index values, with a non-significant statistical correlation. Conclusions: The use of multiple indices in the classification of OSA severity is an important advantage.
Therefore, it can be proved that there is no singular structure to induce the disorder, but the cause is rather a combination of several elements. The polysomnographic examination remains the golden standard for assessing in patients with OSA. Experimental morphologic and radiologic study of the integration of bone grafts into the host tissue and of the dynamics of the graft-receptor interface Horatiu Pompiliu Petrescu, Gabriel Dinu, Gheorghe Noditi, Marcel Berceanu-Vaduva, Dana Cristina Bratu, Dinu Vermesan Bone is the second tissue in terms of number cancer benign tumour transplants after blood.
There is an increased trend of incidence of severe bone lesions with comminuted fractures, with significant lack of substance, as well as an increased incidence of cancer types combined with therapeutic advances in recent decades, allowing for large surgical interventions that affect the bones and create significant defects in bone and contribute to the overall increase in the number and complexity of bone transplants.
Cancer benign tumour may be used singly or in various combinations, with significantly better effects than other implant materials.
Use of autografts is limited by complications from the receptor site, mainly related to infections and undetectable necrotic areas on initial microscopic examination, which prevent proper incorporation of autografts, but also those of the donor situs. The aim of the study was to assess the integration of tibial bone grafts into the femur of Wistar rats by radiologic exam and histological evaluation.

We concluded that the fixing of the graft to the host tissue may be subject to some microenvironment influences. The presence of the periosteum on the grafts is certainly an asset during transplantation. We confirm once again that the ability of transplanted periosteum of osteoformation and reactivation. Our observations regarding the contribution of bone marrow endorse the view of its active role in bone formation. The macroscopic examination of the placental vasculature with a corrosive agent Izabella Petre, Roxana Folescu, Onut Bacean, Anca Bordianu, Ioana Mihaela Luca, Elena Bernad, Marius Lucian Craina The placental development is a complex process, in which any disturbance can induce changes with grave consequences for the offspring.
Villi and villous vascularization development is in, and underdevelopment can lead to villous placental insufficiency. This paper aims to analyze the arterial and venous vasculature of the placenta, both macroscopic and morphologically, by different injection techniques of contrast agents plastic substances type AGO II in cancer benign tumour human placentas with different ages of gestation. A histopathological and immunohistochemical approach of surgical emergencies of GIST.
Also, finding out GIST s pathology has led to a better understanding of oncogenesis and cancer therapy in general. The rapid expansion of molecular and pathological knowledge of GISTs has given this disease a promising future. We analyze 30 cases of GISTs operated on in our clinic with confirmed diagnosis by immunohistochemistry.
Most of the cases were acute cases that required urgent surgical therapy. An extended analysis of cancer benign tumour cases is performed in order to underline their special features.

Of the 30 cases, 15 cases required urgent surgery presenting with GI bleeding or shock following intraperitoneal rupture and bleeding or intestinal obstruction. Of the 15 cancer benign tumour that required urgent surgery 12 cases presented with serosal involvement. Twenty-four cases presented spindle cell histology, four toxin meaning were epithelioid and two cases presented mixed cellularity.
Serosal involvement may warrant the need for a macroscopic classification of GISTs and correlation to therapy. While overall mortality was not high in our cancer benign tumour, morbidity is affected by acute presentation, though not specifically pertaining to the diagnosis of GIST. Serosal involvement was more frequent in the group with acute presentation compared with non-acute GISTs and was present at the most cases of small bowel GISTs with acute onset.
Immunohistochemical and molecular features of primary clear cell-adenocarcinoma of the rectum, as predictive factors for individualized therapy Simona Gurzu, Ioan Jung, Tivadar Bara, Cancer benign tumour Bara Jr.
Surgical resection of the rectum was performed. Intraoperative examination showed a solitary hepatic metastasis; metastasectomy was also performed. Cancer benign tumour examination of the surgical specimen showed mainly a trabecular arrangement of the tumor cells, alternating with tubuloglandular areas, the tumor being diagnosed in stage IV. The tumor was proved to be microsatellite stable, presenting K-ras mutation. Based on the immunoprofile and computer scanning, metastases from clear cell renal cell carcinoma and adrenocortical carcinoma have been excluded.

Based on these characteristics and the tumor stage, the final diagnosis was primary clear cell adenocarcinoma CCA. Bevacizumab-based antiangiogenic therapy was indicated. Completely regressed primary cutaneous melanoma - difficulties in diagnosis and classification Irina Margaritescu, Aurel Doru Chirita, Florina Vasilescu Complete regression cancer benign tumour primary cutaneous melanoma is a very rare phenomenon.
Only 49 cases of well-documented completely regressed primary cutaneous melanoma have been reported to date. The clinical picture and histological findings may vary considerably. The presence of regional lymphadenopathy represents a necessary requisite for the diagnosis of completely regressed primary cutaneous melanoma. However, some cases lie outside these criteria and are difficult to diagnose and classify.
