Abstract
Our group recently developed an innovative maxillary sinus augmentation technique without the need of sinus membrane elevation, termed as "IPG" DET protocol. This technique utilizes autologous platelet concentrates (including platelet rich plasma (PRP), platelet rich fibrin (PRF), growth factors (GFs) and CD34+ stem cells), together with bone grafting materials positioned through intentionally perforated Schneider's membrane for flapless implant placement. This study aimed at evaluating the performance of "IPG" DET protocol in terms of new bone formation and implant stability at 8 months post-op. This prospective study consisted of forty-eight patients with a mean age of 52.8 years. A total of eighty-five implants were placed with "IPG" DET protocol in combination with autologous platelet concentrates. CBCT (cone beam computed tomography) was performed at two different time points: pre-operatively and at 8 months post-op. CBCT images were then compared by an intensity-based image algorithm to assess the newly formed bone in terms of gray scale values. Additionally, implant stability quotient (ISQ) was used to estimate implant osseointegration and success rate. The average new bone formation was 5.9 ± 0.9 mm2 per implant. All implants successfully osseointegrated, and ISQ ranged 62.3-71.7. According to the results of this study, "IPG" DET protocol in combination with autologous platelet concentrates is a successful technique for implant-supported rehabilitation of the edentulous posterior maxilla without the need of sinus floor elevation.

Abstract
Hepatocellular carcinoma is a leading cause of cancer death worldwide in both adult and pediatric patients. Despite many options, no ideal treatment exists for this highly malignant tumor, and management strategies have varied accordingly. Angiogenesis, the formation of new blood vessels, is an essential component of hepatocellular carcinoma biology. Innovative approaches such as targeting the nontransformed, less resistant, tumor-supporting endothelial cells are currently under investigation in hepatocellular carcinoma. This review will focus on the current knowledge of the pathophysiology of hepatocellular carcinoma angiogenesis, as well as the reported data with angiogenesis inhibitors against hepatocellular carcinoma.

Abstract
PURPOSE The aim of the present study was to evaluate the feasibility and efficacy of laparoscopic ventral hernia repair under spinal anesthesia in obese patients (BMI > 30 kg/m(2)). METHODS From January 2007 to February 2010, 23 obese patients had their elective laparoscopic ventral hernia repair under spinal anesthesia. We looked primarily for intra-operative incidences as well as immediate postoperative complications. Long term results and especially recurrences were also to be evaluated. RESULTS Median operative time was 55 min (range 20-100). Intraoperatively, six patients (26%) complained of shoulder pain, three patients (13%) developed bradycardia and two (8.7%) hypotension. Postoperatively, nausea and/or vomiting were recorded in four patients (17.4%), four patients (17.4%) experienced urinary retention and one patient developed wound infection. Median pain score at 4th, 8th and 24th postoperative hour was 0.5 (0-5), 1.5 (0-6), and 1.5 (0-5) respectively. The median length of hospital stay was one day (1-2). At a median follow up of 39 months, one patient was diagnosed with a recurrence. CONCLUSION Spinal anesthesia for LVHR in obese patients (BMI > 30 kg/m(2)) proved an efficient and safe alternative to general anesthesia in the given patient sample.

Abstract
PURPOSE Our group evaluated on a pilot basis open inguinal hernia repair with the use of a fully absorbable mesh aiming to take mesh inguinal hernia repair one step forward. The purpose of the present study was to assess the long-term results of the proposed technique. METHODS Patients that were included in our previous report were followed up at 3 years after the initial operation. RESULTS Ten patients underwent open inguinal hernia repair with the use of an absorbable polyglycolic acid/trimethylene carbonate mesh. 3 years after the procedure, from the total of ten patients, two were lost to follow-up (20 %). Three patients (37.5 %), one with direct and two with indirect hernia, were diagnosed clinically with a recurrence at the follow-up of 3 years. Recurrences were developed nearly 2 years--median 24 months (range 18-30)--after the initial operation. Among patients without recurrence none complained about chronic pain, foreign body sensation or numbness. On the other hand, chronic pain was a constant complain in the recurrence patient group. CONCLUSIONS The results of the 3-year follow-up in the given patient sample alleviate the initial enthusiasm regarding the use of an absorbable mesh for inguinal hernia repair as an attractive alternative and causes skepticism about the generalized use of the procedure in its certain form.

Abstract
Radiation pneumonitis is an acute-phase response to radiation therapy and a common complication that affects a patient's quality of life. Under the need to reduce the incidence and severity of radiation-induced pulmonary complications as well as to identify patients at risk, several investigations on potential predictive markers of radiation pneumonitis have been conducted. The present study reviews the currently available knowledge on biomolecules of potential predictive value for radiation pneumonitis.

Abstract
OBJECTIVE Study the role of hyperglycemia-induced beta cell loss on grafted islet destruction. DESIGN Male inbred rats were made diabetic by streptozotocin administration and used as islet donors and/or isograft recipients to probe directly the role of hyperglycemia as an important determinant of transplanted islet fate, following exclusion of immune-related causes of islet graft destruction like allograft immunity and disease recurrence. RESULTS Our studies showed that: a) Hyperglycemia destroyed islet but not pituitary isografts and b) Tight control of normoglycemia by sufficient islet mass engraftment prevented graft damage. CONCLUSION While sustained hyperglycemia caused destruction of transplanted islet isografts, induction of normoglycemia by transplantation of sufficient islet mass to diabetic recipients had a beneficial long term effect on their functional engraftment.

Abstract
A new technique of dividing the hepatic parenchyma in liver resections is presented. Seven liver resections in six patients were carried out, using a modification of the Radiofrequency assisted hepatectomy technique. The transection zone of the liver was coagulated prior to the division of the parenchyma using a transformed cluster cool-tip Radionics electrode. The reported technique resulted in adequate hemostasis of the raw hepatic surface and minimal blood loss. The aforementioned method seems to be quick and safe especially for local hepatic resections or segmentectomies.

Abstract
Frontal fibrosing alopecia (FFA) was first described in 1994 and is considered a variant of lichen planopilaris in a patterned distribution that primarily affects postmenopausal women. Cicatricial alopecia of the frontoparietal hairline is characteristic; the affected area appears as a shiny, bandlike zone of incomplete hair loss with skin-coloured small hyperkeratotic papules. We describe a case of a premenopausal woman with this rare disease. To date there are very few reports of FFA in premenopausal women. The immunohistochemical investigation with lymphocytic markers (CD4, CD8, CD20, CD45RA, CD57) revealed CD8 positive lymphocytes penetrating the follicular epithelium. Direct immunofluorescence showed clumped deposition of IgM along the follicular basement membrane zone.

Abstract
OBJECTIVE To determine whether estimation of left ventricular (LV) ejection fraction (EF) by means of multiple gated acquisition (MUGA) scanning could reliably stratify cardiac risk prior to elective major vascular surgery. METHODS A review of the English-language literature. RESULTS AND CONCLUSIONS Twenty-two studies enrolling a total of 3096 patients were identified from 1984 to date. Selection bias, blinding of the results, different cut-off limits, and several retrospective studies were some of the problems preventing a comprehensive analysis. The resting LVEF was not found to be a consistent predictor of perioperative ischaemic cardiac events. In the perioperative phase, poor LV function was, mainly, predictive of congestive heart failure, and, in the long-term, of cardiac outcome. The presence of myocardial wall motion abnormalities was also associated with both a higher chance of postoperative cardiac complications and a worse long-term cardiac outcome. Although measurements of LV function seem to play a key role in defining a patient's long-term prognosis, the value of routinely measuring LVEF preoperatively is limited and, therefore, MUGA scanning cannot be recommended as a general screening test. Despite this, it has been widely used for cardiac risk assessment in vascular surgery, and only recently its popularity has started declining. Other tests, such as stress-echocardiography and myocardial perfusion imaging, used selectively in moderate-risk patients can refine prediction of cardiac risk. In the future, gated stress myocardial perfusion scintigraphy, perhaps combined with ANP/BNP plasma level determination, may become a first choice test in preoperative cardiac risk assessment.

Abstract
The monoclonal antibody H (mAbH) detects an epitope consisting of an O-linked N-acetyl glucosamine (O-GlcNAc) and neighboring amino acids. This epitope has been found by using extracts from the MCF-7 human breast carcinoma cell line in immunoblotting experiments, on cytokeratin 8 (CK8) and 5 other polypeptides. In the present study, a double immunogold method was applied for the colocalization of CK8 and mAbH epitope on epoxy thin sections in 18 cases of infiltrating ductal breast carcinomas (IDBC) and in 6 cases of fibroadenomas, to study the accurate subcellular distribution of CK8 in breast cancer cells, as compared to the 5 polypeptides, recognized by mAbH. Furthermore, a detailed quantitative evaluation of the double immunolocalization over the cellular compartments of cancer cells was undertaken with the aid of a computerized image analysis system and the results were assessed statistically. The distribution pattern of CK8 and the mAbH epitope in the neoplastic mammary epithelial cells was similar in IDBC as compared to fibroadenomas, while the gold labeling intensity of these epitopes differed over the cellular compartments between malignant and benign biopsies. The results reveal the significance of the role of CK8 and O-GlcNAc glycosylation in the biology of the neoplastic mammary cells in vivo, determining their malignant potential.

Abstract
AIMS The aim was to analyze the immunohistochemical localization of tetranectin in gastric adenocarcinomas and the adjacent tissues of the wall of the stomach. METHODS AND RESULTS Forty cases of gastric adenocarcinomas were stained by the indirect immunoperoxidase method. Of the ten cases of mucinous signet ring cell carcinomas 5 showed high, 3 moderate and 2 low tetranectin expression. Of the ten cases of well-differentiated intestinal type adenocarcinomas (ITA) 4 showed moderate regional, 3 low regional and 3 negative tetranectin expression. Of the ten cases of moderately-differentiated ITA 3 showed moderate regional, 4 low regional and 3 negative tetranectin expression. Of the ten cases of poorly-differentiated ITA 4 showed focal low and 6 negative tetranectin expression. Overall, the mucinous signet ring carcinomas showed significantly higher tetranectin expression compared to ITA (chi2 = 3.95, p<0.05). In contrast, no significant relationship was found between tetranectin expression and the degree of differentiation in ITA (chi2 = 2.5, p>0.05). In all cases, the perineoplastic desmoplastic reactive stroma showed high expression of tetranectin intra- and extracellularly. The mast cells and goblet cells in the areas of intestinal metaplasia showed high tetranectin expression. CONCLUSIONS This study shows that: a) tetranectin is produced and deposited extracellularly in the desmoplastic peritumoral stroma of infiltrating gastric adenocarcinomas; b) tetranectin is more highly expressed by the mucinous signet ring cell carcinomas compared to ITA; and c) the amount of tetranectin produced by the ITA is unrelated with the degree of tumor differentiation.

Abstract
Cyclin D1 expression was evaluated by immunohistochemical analysis and biotin-labeled in situ hybridization (ISH) in a series of 71 decalcified, paraffin-embedded bone marrow biopsy specimens from patients with multiple myeloma (MM). Cyclin D1 messenger RNA (mRNA) overexpression was detected by ISH in 23 (32%) of 71 cases, whereas cyclin D1 protein was identified by immunohistochemical analysis in 17 (24%) of 71 specimens. All cases that were positive by immunohistochemical analysis also were positive by ISH. Statistically significant associations were found between cyclin D1 overexpression and grade of plasma cell differentiation and between cyclin D1 overexpression and extent of bone marrow infiltration. Our findings demonstrate the following: (1) ISH for cyclin D1 mRNA is a sensitive method for the evaluation of cyclin D1 overexpression in paraffin-embedded bone marrow biopsy specimens with MM. (2) ISH is more sensitive than immunohistochemical analysis in the assessment of cyclin D1 expression. (3) Cyclin D1 overexpression in MM is correlated positively with higher histologic grade and stage.

Abstract
Mantle cell lymphoma (MCL) is characterized by the chromosomal translocation t(11;14), which involves rearrangement of the bcl-1 proto-oncogene to the immunoglobulin heavy chain gene and results in overexpression of cyclin D1 mRNA. In this study, we evaluated the diagnostic relevance of three methods that may be helpful in the diagnosis of MCL: in situ hybridization (ISH) and a stringent reverse transcriptase-polymerase chain reaction (RT-PCR) protocol for cyclin D1 mRNA, and immunohistochemistry for cyclin D1 protein. The study group included 37 paraffin-embedded specimens (25 from lymph nodes and 12 from extranodal tissues) from 30 patients. MCL diagnosis was performed according to the Revised European-American Classification of Lymphoid Neoplasms. Twenty-nine patients with non-MCL lymphoproliferative disorders comprised the control group. Biotin-labeled ISH was performed in 28 cases of MCL, 24 (86%) of which were found to be positive. As shown by ISH in extranodal tissues, cyclin D1 mRNA was present not only in neoplastic lymphoid cells, but in other cell types as well. For this reason, RT-PCR results were considered reliable for MCL diagnosis only on informative material (from tissues that do not normally express cyclin D1); this method was evaluated as positive in 16 of 18 (89%) MCL cases. Cyclin D1 immunopositivity was present in 20 of 29 (69%) MCL cases. No members of the control group were found to express cyclin D1 mRNA by either ISH or RT-PCR under the stringent conditions used. In conclusion, stringent RT-PCR for cyclin D1 expression can be helpful in MCL diagnosis in paraffin-embedded material from lymph nodes. ISH is a sensitive method for cyclin D1 mRNA detection; its sensitivity is superior to that of cyclin D1 immunohistochemistry and similar to that of the stringent RT-PCR used. ISH is very specific as well, clearly more specific than RT-PCR, because it allows the correlation of molecular findings with morphology. This method can be applied on all types of paraffin-embedded tissues and provides an accurate tool for MCL diagnosis.

Abstract
The purpose of the present study was to examine whether its is possible to successfully replace ondansetron (OND) with metoclopramide (MCP) in patients exposed to moderately emetogenic chemotherapy who did not experience severe nausea and vomiting while undergoing OND treatment during their first chemotherapy cycle. After switching to MCP, patients continued with this drug for three cycles, provided that they had adequate control of nausea and vomiting. Otherwise, they were switched back to OND. There were 76 patients, 60 women and 16 men, whose median age was 56 (mean 58) years. Karnofsky performance status score was 100 in 18 patients, 90 in 23, and 80 in 11 patients. No patient had previous chemotherapy. Thirty-four patients had breast cancer and received fluorouracil 500 mg/m2, epirubicin 100 500 mg/m2, and cyclophosphamide 500 mg/m2. Twelve patients had small cell lung cancer and received carboplatin 400 mg/m2 + etoposide 120 mg/m2 x 3 days. Twenty patients with ovarian cancer received carboplatin 350 mg/m2 and cyclophosphamide 500 mg/m2. Ten patients had cancer of unknown primary and received carboplatin 400 mg/m2, epirubicin 60 mg/m2, and etoposide 120 mg/m2 x 3 days. The OND schedule consisted of methylprednisolone 40 mg intravenous bolus followed by OND 8 mg in a 15-min infusion before chemotherapy, followed by OND 4 mg orally x 3 on the same and the next 2 days. Patients who did not experience nausea and vomiting with OND continued with an MCP schedule consisting of methylprednisolone 40 mg bolus followed by MCP 2 mg/kg in a 15-min infusion before chemotherapy, followed by MCP (20 mg x 4 on the day of therapy and the next 2 days after). Patients who failed with MCP or OND continued with OND. Considering our results as a whole, the intensity of nausea does not appear to influence the results of Gralla's scale. The results of Gralla's scale do not appear to be affected by the analysis of the antiemetic results and nausea on the next 2 days following chemotherapy administration. Overall, patients received 145 cycles with OND and 159 cycles with MCP. Of the 76 patients receiving OND-based antiemetic regimen during the first cycle, 13 (21%) experienced severe vomiting (Grade 2, 3) and the remaining 63 (79%) had mild or no vomiting (Grade 0, 1). Patients with Grade 0, 1 vomiting (63, 83%) continued with MCP in the second cycle. The final number of patients who failed on MCP, after 4 cycles of chemotherapy increased to 33 (43%); 43 (57%) were able to complete chemotherapy with MCP. Headache occurred in 15 (10%) cycles with OND and 8 (5%) with MCP. Flushing was noted in 12 (8%), and constipation occurred in 43 (30%) of OND cycles, and extrapyramidal manifestations occurred in 3 (5%) of patients receiving MCP. Diarrhea was noted in 3 (2%) of cycles with OND and in 28 (18%) with MCP. The cost ratio between MCP and OND was 1:14. If we administered OND only in patients who needed it, the overall cost decreased to 44%. Following the strategy applied in the present study, the cost decreased to 47%.

Abstract
Forty-three patients (two males and 41 females) were submitted to bilateral adrenalectomy for disseminated mammary carcinoma. Several factors were considered for their prognostic value in predicting the response to endocrine ablation. The age of the patients, the treatment of the primary lesion, the free interval, the location of metastases and the involvement of regional lymph nodes did not affect the response to adrenalectomy. Response to therapeutic castration was directly correlated to the response to adrenalectomy (P less than 0.01); this is a valuable predicting factor that should be taken into consideration before proceeding to bilateral adrenalectomy. A statistically significant variation in survival between the responders and nonresponders was found (P less than 0.05). Finally, the high response rate to the operation (53.4%) can be attributed to the complete removal of the adrenal tissue during the operation.
