Abstract
Nowadays, there is an increasing knowledge that probiotic bacteria, topically applied, affects skin pathology. The objective of this study is to evaluate the effect on wound healing of locally applied probiotics by calculating the 3-D configuration of a standardized excisional wound. Fifty-two male Wistar rats were randomly allocated into groups: control, PRO1 [L. plantarum] and PRO2 [L. rhamnosus, B. longum]. Six excisional full-thickness wounds were created on each dorsum by an 8-mm circular biopsy punch; probiotics or saline were applied on days 0, 2, 4, 8, 16, photos of the wounds taken and specimens excised for histology [4 rats/group/time-point]. Both probiotic-groups exhibited accelerated healing significantly faster than the control, throughout, PRO2 exhibiting finally the best results [day 16]. However, only on day 2, did PRO1 exhibit the best results [wounded area, borders distance and epitheliazation line]. The results clearly demonstrate that the topical application of probiotics significantly improves the healing process, each strain working differently and more effectively in different healing phases. Thus, a combined formula containing different probiotics to modulate various healing phases is desirable. To this end our research continous.

Abstract
BACKGROUND We asked whether open reduction and internal fixation (ORIF) or radial head arthroplasty (RHA), common techniques used for the confrontation of displaced or comminuted radial head fractures, are correlated with cartilage wear of the capitulum. HYPOTHESIS We hypothesized that neither ORIF nor RHA are correlated with capitellar cartilage wear. MATERIAL AND METHODS On 5 cadaveric elbow specimens, osteotomies were employed to simulate radial head comminuted fractures followed with ORIF by Herbert screws. Radial heads were also excised from other 5 cadaveric elbow specimens and were replaced by metallic monopolar implants. Finally, 2 elbows were not operated and used as a control group. Custom-made rotary machines, working unstoppably, generated 700,000 pronation and supination forearm movements at a 110° arc of motion. The elbow joints were examined with pre- and postoperative magnetic resonance imaging (MRI) scans and the articular surfaces of the capitula were resected and sent for histopathology study. RESULTS In the 2 cadaveric elbows of the control group and the 4 elbows treated with ORIF, no cartilage damage was found. The fifth one displayed cartilage fissures, which were, classified according to International Cartilage Repair Society (ICRS) grading system as grade I cartilage damage. On the contrary, all 5 elbows treated with RHA sustained complete cartilage loss, exposure of the subchondral bone and were classified as ICRS grade IV cartilage damage. DISCUSSION Our study suggests that metallic monopolar RHA after a displaced or comminuted radial head fracture carries a high risk of rapidly evolving cartilage loss of the capitulum.

Abstract
AIM To evaluate the effect of local surgical adhesive glue (albumin/glutaraldehyde-Bioglue) on the healing of colonic anastomoses in rats.
METHODS Forty Albino-Wistar male rats were randomly divided into two groups, with two subgroups of ten animals each. In the control group, an end-to-end colonic anastomosis was performed after segmental resection. In the Bioglue group, the anastomosis was protected with extraluminar application of adhesive glue containing albumin and glutaraldehyde. Half of the rats were sacrificed on the fourth and the rest on the eighth postoperative day. Anastomoses were resected and macroscopically examined. Bursting pressures were calculated and histological features were graded. Other parameters of healing, such as hydroxyproline and collagenase concentrations, were evaluated. The experimental data were summarized and computed from the results of a one-way ANOVA. Fisher’s exact test was applied to compare percentages.
RESULTS Bursting pressures, adhesion formation, inflammatory cell infiltration, and collagen deposition were significantly higher on the fourth postoperative day in the albumin/glutaraldehyde group than in the control group. Furthermore, albumin/glutaraldehyde significantly increased adhesion formation, inflammatory cell infiltration, neoangiogenesis, and collagen deposition on the eighth postoperative day. There was no difference in fibroblast activity or hydroxyproline and collagenase concentrations.
CONCLUSION Albumin/glutaraldehyde, when applied on colonic anastomoses, promotes their healing in rats. Therefore, the application of protective local agents in colonic anastomoses leads to better outcomes.

Abstract
Background Fournier’s gangrene (FG) is a rapidly evolving necrotizing fasciitis of the perineum and the genital area, the scrotum as it most commonly affects man in the vast majority of cases. It is polymicrobial in origin, due to the synergistic action of anaerobes and aerobes and has a very high mortality. There are many predisposing factors including diabetes mellitus, alcoholism, immunosuppression, renal, and hepatic disease. The prognosis of the disease depends on a lot of factors including but not limited to patient age, disease extent, and comorbidities. The purpose of the study is to describe the experience of a general surgery department in the management of FG, to present the multimodal and multidisciplinary treatment of the disease, to identify predictors of mortality, and to make general surgeons familiar with the disease. Methods The current retrospective study is presenting the experience of our general surgery department in the management of FG during the last 20 years. The clinical presentation and demographics of the patients were recorded. Also we recorded the laboratory data, the comorbidities, the etiology, and microbiology and the therapeutic interventions performed, and we calculated the various severity indexes. Patients were divided to survivors and non-survivors, and all the collected data were statistically analyzed to assess mortality factors using univariate and then multivariate analysis. Results In our series, we treated a total of 24 patients with a mean age 58.9 years including 20 males (83.4%) and 4 females (16.6%). In most patients, a delay between disease onset and seeking of medical help was noted. Comorbidities were present in almost all patients (87.5%). All patients were submitted to extensive surgical debridements and received broad-spectrum antibiotics until microbiological culture results were received. Regarding all the collected data, there was no statistically significant difference between survivors and non-survivors except the presence of malignancy in non-survivors (p = 0.036) and the lower hemoglobin (p < 0.001) and hematocrit (p = 0.002) in non-survivors. However, multivariate analysis did not reveal any predictor of mortality. Conclusion Early diagnosis, aggressive thorough surgical treatment, and administration of the proper antibiotic treatment comprise the cornerstone for the outcome of this disease. In small populations like in the present study, it is difficult to recognize any predictors of mortality and even the severity indexes, which take into account a lot of data cannot predict mortality.

Abstract
Epithelial-myoepithelial tumors of the lung are rare neoplasms whose biological behavior and clinical course still remain to be defined. Epithelial-myoepithelial carcinoma (EMCa) is a low-grade malignant tumour. According to literature, most commonly occurs in salivary glands, particularly in parotic gland, but it can also occur in unusual locations such as breast, lachrymal gland, nose, paranasal sinus, lung, bronchus and, as in our case, trachea. There are no many documented case reports of a primary myoepithelial carcinoma in the trachea. We report a case of a 34-year-old man diagnosed with this unusual location of an epithelial-myoepithelial tumor. The tumour was removed by segmental tracheal resection and end-to-end anastomosis.

Abstract
Nutrition has been known for ages to shield the immune system against several formulations that deregulate normal DNA repair mechanisms, and induce tumorigenesis. Vitamins and in specific Vit E and its members tocopherols (α-, β-, γ-, δ-) and tocotrienols (α-, β-, γ-, δ-) have demonstrated strong association with the prevention of cancer and inhibition of tumor, both in vitro and in vivo. Vitamin E has also demonstrated effective role against chemotherapy resistant cancer cell evolution and a protective role in acute interstitial disease. Several formulations of Vitamin E have been investigated conjugated with different carriers as nano-formulations and administered in different forms. Additionally, several tumorigenic pathways have been investigated separately in an effort to identify which member of Vitamin E inhibits efficiently every pathway. Vitamin E presented efficiency against specific subhistology types of lung cancer. Finally, in the current work up to date information regarding novel formulations with Vitamin E and inhibition pathways are going to be presented and commented.

Abstract
Neuroendocrine tumours of the extrahepatic bile ducts are extremely rare with less than 70 cases having been reported in the literature. Neuroendocrine tumours are neoplasms of variable malignant potential that arise from the embryonic neural crest cells. They most commonly occur in young females and usually present with painless jaundice. Preoperative diagnosis is seldom made and neuroendocrine tumours are usually incidentally found during abdominal surgical intervention for other indication. Due to their indolent biological behaviour aggressive surgical treatment is recommended. We present a case of an incidentally discovered neuroendocrine tumour of the cystic duct in a 41 year old woman following laparoscopic cholecystectomy for symptomatic gallbladder microlithiasis. The present case is the 8th case of cystic duct NET and the 63rd of extrahepatic bile duct NET. While a rare location for a NET, it is important to report cases of biliary tract neuroendocrine tumours in order for their pathogenesis and physical history to be clarified.

Abstract
The purpose of this prospective experimental and clinical study is to evaluate the effectiveness of the intralesional injection of platelet-rich plasma (PRP), in the management of non-healing chronic wounds. Skin defects were created in the ears of 20 white New Zealand rabbits. In the study group, autologous PRP was injected intralesionally. The control group was treated conservatively. Nineteen out of 20 cases of the study group healed within a mean time of 24·9 days. In the control group, seven defects healed within a mean period of 26·7 days, seven ulcers did not heal at day 28 and in six cases a full thickness ear defect was recorded. For a 3-year period, 26 patients with chronic ulcers underwent surgical debridement and intralesional injection of PRP. A histological study was performed before and 7 days after PRP injection. Ten patients healed within a mean period of 7 weeks. In 16 cases, PRP prepared the wound bed for the final and simpler reconstructive procedure. Intralesional injection is a newly described method for application of PRP and represents an effective therapeutic option when dealing with non-healing wounds.

Abstract
Mesenteric cysts are rare cystic malformations of the mesentery. They are usually located at the iliac mesentery. Clinically most mesenteric cysts are asymptomatic, but sometimes they present with non-specific abdominal symptoms. Diagnosis can be aided using US, CT and MRI but careful interpretation of the images and high index of suspicion of this rare condition is essential for the correct diagnosis, which cannot always be preoperatively established. The therapeutic method of choice is complete surgical excision of the cyst which minimizes the possibility of recurrence. Histopathologically they are classified in six group. We present a case of a mesothelial mesenteric cyst in patient with colon cancer. The cyst was misdiagnosed as urinary bladder diverticulum in the preoperative CT scan.

Abstract
INTRODUCTION We present a case of an aggressive osteoblastoma involving the posterior acetabular column and the ischium, which is very rare location for the tumor. CASE PRESENTATION A 21-year-old man presented with a persistent pain on the left buttock which extended on the rear surface of the thigh and the front surface of the left hip. A plain radiograph, a CT and MRI examinations were performed. The tumor was radically excised and histologically it proved to be an aggressive osteoblastoma. CONCLUSIONS Although aggressive osteoblastoma is a rare entity it should be considered in the differential diagnosis of bone tumors. Our purpose is to reveal the radiographic presentation of this rare tumor.

Abstract
Myeloid sarcoma, which is highly associated with acute myeloid leukemia, is defined as an extramedullary discrete tumor mass, consisted by immature myeloid cells or myeloblasts. Myeloid sarcoma usually involves the skin, lymph node, bone, soft tissue and testis, while involvement of the gastrointestinal tract is rather uncommon. The diagnosis depends on histological features and immunohistochemical results. We present a rare case of myeloid sarcoma, with synchronous involvement of the jejunum and the greater omentum, manifesting with small bowel obstruction.

Abstract
OBJECTIVE To determine the role of tenascin-C in fetal hepatic hematopoietic proliferation and differentiation in different stages of development. STUDY DESIGN We examined and compared the immunohistochemical expression of tenascin-C in the hepatic stromal portal fields in the first, second, and third trimester of gestation respectively, in relation to the appearance of CD34 progenitor hematopoietic, stromal progenitor and vascular endothelial positive cells. RESULTS Our results demonstrated a quantitative difference in the second trimester of gestation concerning the expression of tenascin-C in the connective tissue stroma of the hepatic portal fields over the equivalent expression of the protein in the first (P<0.0001, t-test) and third trimester (P<0.0001, t-test). Similar changes in the above period were found concerning the expression of CD34 over the first (P<0.0001, t-test) and third trimesters (P<0.0001, t-test), suggesting a direct involvement of tenascin-C in the sustaining of hematopoietic activity. CONCLUSIONS Our data provide evidence that an ECM glycoprotein component, tenascin-C, plays a relevant role in hematopoiesis through interaction between stromal cells and hematopoietic progenitor cells.

Abstract
The presence of myoid cells (MCs) - stromal cells with myogenic differentiation - in human bone marrow (BM) has been observed during hematopoiesis in embryonic life, whereas during adult life, it is strictly related to various pathologic conditions. The aim of this study was to examine the presence, distribution and quantitation of cells in the stroma of the BM expressing alpha-smooth muscle actin (alpha-SMA) in reactive BM plasmacytosis and plasma cell myeloma. For this reason, a series of 10 trephine BM biopsies from patients with plasma cell myeloma and 10 specimens from healthy controls with reactive plasmacytosis were examined for the presence of stromal cells with myoid differentiation, using a monoclonal antibody recognizing alpha-SMA. Our results suggest that the incidence of MCs and subsequent fibrosis rises in plasma cell myeloma and in a lesser degree in the BM stroma of individuals with reactive plasmacytosis.

Abstract
Serous papillary ovarian cancer (SPC) is a highly aggressive tumor. About two-thirds of women have advanced disease at the time of diagnosis. Although many women with disseminated disease respond at first to combinations of surgery and chemotherapy, nearly 90% of tumors recur and women die of disease. Update progress in our knowledge of tumor-associated antigens and insight into mechanisms involved in immune-mediated recognition of these antigens, have provided a strong starting point for using the immune system as a model for novel therapy. In this study we determined the immunological profile of tumor-infiltrating lymphocytes (TILs), tumor-associated lymphocytes (TALs) in ascitic fluids, and lymphocytes from tumor draining regional lymph nodes (LNs) in SPC patients by CD20 (L26), CD8, and CD56 immunostaining. We examined 14 cases of TILs, 15 cases of TALs and 19 cases of LNs. TILs were infiltrating tumor stroma. No significant difference was detected in TILs, TALs and LNs in the expression of the B-cell marker CD20. In contrast, CD8 (T-cytotoxic) and CD56 (natural killer cell, NK) markers were dominant in LNs and TALs, but not in TILs. We conclude that SPC tumor lymphocytic infiltrate demonstrates a deplete T cytotoxic (CD8+) and NK cell (CD56+) immunophenotypic profile. This might in part explain the poor clinical outcome of the disease.

Abstract
CD44 is an adhesion molecule, which binds hyaluronic acid and participates in a number of cell-cell interactions, including lymphocyte homing. The CD44 antigen is expressed on approximately 90% of lymphocytes, monocytes, granulocytes, and, in lower amounts on thymocytes, fibroblasts, and erythrocytes. Platelets lack CD44. In non-haematopoietic tissues, CD44 is widely distributed. The secretory component is isolated from human colostrum and is of help in more precise grading of endometrial carcinoma. In this study we examined CD44 and secretory component expression in adenomatous hyperplasia, atypical adenomatous hyperplasia and well-differentiated adenocarcinoma (cribriform pattern). The results showed decreased expression of CD44 and increased expression of secretory component as the lesion progressed to malignancy.

Abstract
Vimentin is an intermediate filament protein normally expressed in mesenchymal cells, but evidence is accumulating in the literature which suggests that the aberrant expression of vimentin in epithelial cancer cells might be related to local invasiveness and metastatic potential. Previous studies strongly support the implication of vimentin in the metastatic progression of breast and cervical lesions. The secretory component is isolated from human colostrum and is of help in more precise grading of endometrial carcinoma. In this study we examined vimentin and secretory component (SC) expression in adenomatous hyperplasia, atypical adenomatous hyperplasia and well-differentiated adenocarcinoma (cribriform pattern). The results showed decreased expression of vimentin and increased expression of the secretory component as the lesion progressed to malignancy.

Abstract
Myoepithelial cells are normally located between the epithelial cells and the basal lamina of secretory elements of exocrine glands. Their role in the histogenesis of breast tumours has been studied extensively, and a definite differentiation towards myoepithelial cells has been demonstrated in adenoid cystic carcinoma, adenomyoepithelioma, low-grade adenosquamous (syringomatous) carcinoma, pure malignant myoepithelioma and poorly differentiated myoepithelial-rich breast carcinoma. All these tumours are of low malignancy, with the exception of malignant myoepithelioma and poorly differentiated myoepithelial-rich carcinoma. We examined the possibility that invasive ductal carcinoma of the breast might show differentiation towards both epithelial and myoepithelial cells because there is no reason to assume that one type of differentiation necessarily excludes the other. We performed the avidin-biotin immunohistochemical analysis of 20 cases of infiltrating ductal carcinomas (IDCs) with diffuse fibrosis, 20 cases of IDCs without fibrosis and five cases of metaplastic carcinomas, to detect myoepithelial differentiation of the tumour cells. Myoepithelial differentiation was determined by the expression of alpha-smooth muscle actin (alpha-SMA). We concluded that IDCs with diffuse fibrosis are associated with a myoepithelial immunophenotype of carcinoma cells.

Abstract
Medullary carcinoma (MC) of the breast is considered to carry a more favorable prognosis than other subtypes of infiltrating ductal carcinoma. This is a biological paradox because its clinical behavior contrasts with its anaplastic morphology. MC is characterized by a dense lymphocytic infiltrate. In this study, we determined the immunological profile of tumor infiltrating lymphocytes (TILs) in MC by CD20 (L26), CD8, and CD45RO (UCHL 1) immunostaining on paraffin-embedded sections. We examined 14 cases of typical MC (TMC), 15 cases of atypical MC (AMC) classified according to Ridolfi criteria (1977) and 19 cases of poorly differentiated infiltrating ductal carcinoma (PDC-NOS). TILs were quantified separately into cells infiltrating tumor nests (intraepithelial) and cells infiltrating tumor stroma (stromal). The number of CD8 positive and CD20 positive cells infiltrating tumor nests and tumor stroma were significantly increased in TMC and AMC as opposed to the PDC-NOS group. There was a loss in the number of CD45RO positive cells, both intraepithelial and stromal, in TMC and AMC as opposed to the PDC-NOS group. We conclude that MC tumor lymphocytic infiltrate demonstrates a mixed-T cytotoxic (CD8+) and B cell (CD20+)-immunophenotypic profile. This might in part explain the improved clinical outcome of the disease.

Abstract
BACKGROUND Small-cell lung carcinoma (SCLC) is a highly malignant tumour of a somewhat distinctive cell type. The aim of this study was to determine the immunocytochemical profile of tumor cells and lymphoid cell in SCLC pleural fluids. METHODS Nine cases of malignant pleural fluids of SCLC were studied using cell block preparation. In pleural effusions cytologically proven to be malignant in 9 patients with SCLC, the immunocytological features of tumor cells, together with the determination of lymphocytic subsets were documented. RESULTS In all 9 cases, tumor cells reacted with neuron-specific enolase (NSE) (100%), whereas in 6 of 9 cases (66,66%) tumor cell expressed synaptophysin, thyroid transciption factor-1 (TTF-1) and chromogranin A antigens. Phenotyping of the lymphocytes revealed in the majority of cases an expression of CD3 and CD4 antigens (8 and 7 cases, respectively) in contrast to CD8 and CD20 expression (1 and 1 case, respectively). CONCLUSIONS The reactivity pattern of the tumor cells with the markers used in our study is a specific for SCLC. No significant difference in the distribution of lymphocytic subpopulations is observed in correlation with other malignant and no malignant processes involving the pleural cavity.
