Abstract
Isolated ventricular premature beats (VPBs) are commonly found during pre-participation screening in athletes. Currently, the debate about the role of detraining in reducing the number of VPBs is still open. This study evaluated the arrhythmic risk in a population of young competitive athletes who showed VPBs during eligibility evaluation and that did not undergo detraining but continued practicing competitive sports. 3746 consecutive subjects underwent pre-participation screening. Athletes who showed VPBs were selected and underwent second level evaluation (Echocardiogram, 24 hour Holter ECG and Exercise test). Athletes were re-evaluated after a follow-up period (6-48 months) while they continued practicing competitive sports. 5.3% of the whole population showed ventricular arrhythmias. 73% of the subjects showed isolated VPBs. 88% of the subjects showed monomorphic VPBs, and 12% of athletes showed polymorphic VPBs. At echocardiogram, there was not any pathology which contraindicated competitive sport activity. At 24 hour Holter ECG recording, mean number of daily VPBs was 1592±3217 (range 0-16678). At holter ECG follow-up (16±12 months), the median number of VPBs decreased from 93 (IQR 20-3065) to a new value of 72 (IQR 2-1299). Continuing competitive sport in subjects with ventricular arrhythmias even though frequent but with a low grade of complexity and without structural cardiomyopathy does not increase sudden death risk.

Abstract
Equine hepacivirus is the closest homologue of hepatitis C virus. Limited data on the clinical features of this infection are available. We report the identification of a horse with high-titre viremia by equine hepacivirus. Over a 15-month follow-up, the clinical signs and the viremic status persisted, suggesting a chronic evolution.

Abstract
Foreign body ingestion is not an uncommon problem in clinical practice. While most ingested foreign bodies pass uneventfully through the gastrointestinal tract, sharp foreign bodies such as toothpicks should cause intestinal perforation. We reported the case of a perforation of the appendix caused by a toothpick, which also pierced the liver without hepatic damages, in a male with an intestinal malrotation and subhepatic appendix. The patient was admitted to our hospital for abdominal pain in the right upper quadrant. An abdominal computed tomography scan revealed the anomalous position of the first portion of the large intestine with inflamed appendix. A laparoscopic appendicectomy and the exploration of the abdominal cavity was performed using minimally invasive technique.

Abstract
PURPOSE The use of recombinant human growth hormone (rhGH) is a common habit among athletes. While the effects of rhGH administration have been described with contrasting results in males, no data exist in females to date. The aim of the present study was to evaluate the effects of rhGH administration on TSH, FT4 and FT3 levels and the time requested to return to baseline values after treatment withdrawal. METHODS Twenty-one healthy trained male and female athletes were treated with 0.03 mg rhGH/kg body mass 6 days/week for 3 weeks. We collected blood samples immediately before the first daily rhGH administration, at 3, 4, 8, 15 and 21 days of treatment and at 3 and 9 days after rhGH withdrawal. RESULTS In males, rhGH administration induced a significant (p < 0.01) early and stable TSH decrease and IGF-I increase, and a delayed FT4 reduction without FT3 modification, suggesting a central regulatory mechanism. In females, rhGH administration induced a significant (p < 0.01) early and transient TSH decrease and IGF-I increase, and a transient reduction in FT4 without any changes in FT3 concentrations. rhGH withdrawal was associated with a prompt normalization of TSH and FT4 levels in males, while in females the effects of rhGH treatment had already disappeared during the last period of treatment. CONCLUSION We suggest that rhGH inhibits TSH at central level both in males and females. The pattern of normalization was different in the two genders probably due to gonadal steroids modulation on GH-IGF-I axis.

Abstract
Recently, bovine viral diarrhoea virus type 2c (BVDV-2c) was responsible for a severe outbreak in cattle in northern Europe. Here, we present the results of an epidemiological survey for pestiviruses in ruminants in southern Italy. Pooled serum samples were obtained from 997 bovine, 800 ovine, 431 caprine and eight bubaline farms, and pestiviral RNA was detected by molecular methods in 44 farms consisting of 16 cattle and one buffalo herds and of 21 sheep and six goat flocks. Twenty-nine and 15 farms were infected by BVDV-1 and BVDV-2 strains, respectively. BVDV-1 strains were recovered mainly from cattle and were heterogeneous, belonging to the subtypes 1b, 1u, 1e, 1g and 1h. In contrast, all BVDV-2 viruses but two were detected in sheep or goats and were characterized as BVDV-2c by sequence analysis of 5'UTR. These strains displayed high genetic identity to BVDV-2c circulating in cattle in northern Europe and were more distantly related to a BVDV-2c isolate recovered from a cattle herd in southern Italy more than 10 years before. The circulation of a BVDV-2c in small ruminants suggests the need for a continuous surveillance for the emergence of pestivirus-induced clinical signs in southern Italian farms.

Abstract
OBJECTIVES The aim of the study was to evaluate the effects of a combined aerobic and strength program on physiological and psychological parameters in female breast cancer survivors. STUDY DESIGN Randomised controlled trial. METHODS 20 patients (age: 45.6 ± 2.7 yrs) surgically treated for breast cancer that had completed all cancer therapies at least 6 months before and with no contraindications to physical activity, were recruited and randomly assigned to an intervention group (n = 10) and a control group (n = 10). Intervention group patients attend to a 24-week combined aerobic and strength training program. Physiological (i.e. VO2max, bioelectrical impedance test, maximal strength of principal muscular groups) and psychological (i.e. functional assessment of chronic illness therapy-fatigue: FACIT-F) parameters were assessed at baseline and after 24 weeks. RESULTS After 24 weeks the intervention group showed significant improvement in VO2max (38.8%), strength of upper and lower limbs (ranging from 13 to 60%) and decrease in fat mass percentage (-6.3%). The FACIT-F showed significant increase in all of the three scores that can be derived (FACIT-F Trial outcome: 13%; FACT-G total score: 18%; FACIT-F total score: 15%) showing patient's quality of life (QOL) improvement. No significant change in all the parameters was found for the control group. CONCLUSION These results show the positive effects of a combined aerobic and strength training program on breast cancer survivors and underline the importance of the early inclusion of structured physical activity in the rehabilitation protocol.

Abstract
AIMS The present study aimed to determine, by multilocus sequence type (MLST), the heterogeneity level of Arcobacter butzleri isolates and to compare MLST and pulsed-field gel electrophoresis (PFGE) in terms of discriminatory power (DI) as well as unidirectional and bi-directional concordance. METHODS AND RESULTS Arcobacter butzleri isolates (N = 133) from dairy products and environmental samples, collected from dairy plants, were characterized by MLST and PFGE with SacII and classified in 29 sequence types (STs), 47 PFGE and 62 type strains (TS). Among the 119 alleles, 19 were previously unreported and the same for all the STs but two. A significant linkage disequilibrium was detected when the complete ST data set was analysed The DIs of MLST, PFGE and their combination were 0·937, 0·953 and 0·965 respectively. The adjusted Wallace coefficients between MLST and PFGE as well as PFGE and MLST were 0·535 and 0·720 respectively; the adjusted Rand coefficient was 0·612. CONCLUSIONS The A. butzleri studied population showed recombination to some degree. PFGE showed a DI higher than MLST. Both methods presented good concordance. The TS analysis seems to show persistence of the same strain on time and possible cross-contaminations between food and environmental sites. SIGNIFICANCE AND IMPACT OF THE STUDY This study provides insights in the A. butzleri population found in raw milk, cheese, and dairy production plants. The data suggest that MLST and PFGE genotypes correlate reasonably well, although their combination results in optimal resolution.

Abstract
A case of desmoplastic variant of diffuse-type gastric carcinoma in a 72-year-old woman is reported. Microscopic findings included poorly cohesive tumor cells, resembling mononuclear inflammatory cells, prominent diffuse desmoplasia, and tumor-associated tissue eosinophilia. Electron microscopy confirmed the undifferentiated phenotype of tumor cells and disclosed activated eosinophils in the tumor stroma. Eosinophil-specific granules were found either free in the tumor stroma or within the cytoplasm of some tumor cells. Electron microscopy provided also circumstantial evidence of phagocytosis of apoptotic eosinophils by tumor cells. Extracellular, membrane-bound, eosinophil-specific granules have been long recognized in tissues associated with eosinophilia, including allergic diseases, inflammatory responses to helminths, and in stroma of some neoplasms. Our ultrastructural study now extends these findings and provides additional morphological evidence of eosinophil-specific granules within the cytoplasm of gastric carcinoma cells.

Abstract
BACKGROUND/AIM Neutrophil-rich carcinoma is a variant of gastric carcinoma that has not been well-studied or characterized. The purpose of the present study was to reveal the incidence and clinicopathological findings compared to ordinary gastric carcinoma. PATIENTS AND METHODS A population-based series of 430 gastric cancers, identified between 2003 and 2006 from the province of Messina (insular Italy; population, 662,450), was used. The number of tumor-infiltrating neutrophils was assessed in a semi-quantitative manner using the mean value of 20 non-overlapping high-power fields (magnification, 400; 0.08 mm(2)). Tumors with >10 neutrophils per 20 high-power fields were arbitrarily considered as neutrophil-rich gastric carcinomas. Moreover, MUC1 immunohistochemical expression was investigated to show possible correlation with neutrophil infiltration in gastric carcinomas. RESULTS Among 193 gastric cancers resected for curative purposes, 30 (15.54%) were represented by neutrophil-rich gastric carcinomas. These tumors occurred more frequently in patients aged more than 72 years (p<0.05), showing an inverse correlation with mucinous subtype according to the WHO classification (p<0.001) and expressed MUC1. However, intensity and distribution of MUC1 was heterogeneous, and independent of neutrophil infiltration within the tumor stroma. CONCLUSION Neutrophil-rich carcinoma seems to represent a distinctive morphological variant of gastric carcinoma, although the true mechanism for the infiltration of neutrophils is still unclear.

Abstract
AIM A meta-analysis was performed to compare the outcome of single incision laparoscopic right hemicolectomy with standard multiport laparoscopic right hemicolectomy. METHOD A systematic search of databases was carried out to extract comparative studies (randomized and non-randomized, prospective and retrospective). Data were analysed according to Cochrane Collaboration guidelines. A meta-analysis was performed when the data permitted this form of analysis. RESULTS Nine comparative studies were retrieved comprising 241 patients with single incision and standard laparoscopy. None of these was randomized. There was no significant difference between the two methods for the primary end-points of mortality, morbidity and cancer-specific parameters and for the secondary end-points of operation time, blood loss, ileus, hospital stay and conversion. It was not possible to analyse pain and cosmetics data owing to insufficient information. CONCLUSION Single incision laparoscopic right hemicolectomy is comparable with standard multiport laparoscopic right hemicolectomy in primary and secondary outcomes. Given current information it is justified to use single incision laparoscopic right hemicolectomy, but there is a need for a prospective randomized study.

Abstract
We performed a pilot study using human peripheral blood lymphocytes (PBL) as a novel system to identify new biomarkers of dihydrotestosterone (DHT) and insulin-like growth factor-1 (IGF-1) abuse in sport. First, to obtain a gene signature, we treated cultures of lymphocytes from sedentary males with three doses of 0.237 microg/ml DHT, each of which is 80-fold the physiological concentration in young adult male serum, at days 0, 2 and 4, or with a single dose of 1.25 microg/ml IGF-1, which is 5-fold the physiological concentration in young adult male serum. We then used the Human Genome U133 Plus 2.0 microarray to identify a gene signature related to DHT or IGF-1 administration. Gene expression was evaluated after 7 and 21 days of DHT treatment, and after 24 h, 72 h and 7 days of IGF-1 treatment. Microarray analysis yielded a list of genes whose expression was altered after DHT or IGF-1 treatment. Among these we selected the genes that are most representative of the pathways associated with skeletal and muscular disorders using the IPA bioinformatics tool. We identified six (IDO1, CXCL13, CCL1, GZMB, VDR and IL2RA) and two (FN1 and RAB31) genes that were up-regulated in lymphocytes from sedentary subjects after 7 days of DHT and IGF-1 treatment, respectively. The expression of these genes in lymphocytes from differently trained athletes was either down-regulated or similar to that in lymphocytes from sedentary subjects. This finding suggests that up-regulation was due to the drug and not to physical exercise. In conclusion, we demonstrate that PBL can be useful in anti-doping checks, and we describe new biomarkers of DHT and IGF-1 abuse which can be included in the Athlete's Biological Passport.

Abstract
BACKGROUND Single-incision laparoscopic cholecystectomy (SILC) may offer advantages over conventional laparoscopic cholecystectomy (LC). METHODS MEDLINE, Embase, PubMed, CINAHL, Cochrane Central Register of Controlled Trials and the Cochrane Library were searched for randomized clinical trials on SILC versus LC until May 2012. Odds ratio (OR) and weight mean difference (WMD) were calculated with 95 per cent confidence intervals (c.i.) based on intention-to-treat analysis. RESULTS Thirteen randomized clinical trials included a total of 923 procedures. SILC had a higher procedure failure rate than LC (OR 8·16, 95 per cent c.i. 3·42 to 19·45; P < 0·001), required a longer operating time (WMD 16·55, 95 per cent c.i. 9·95 to 23·15 min; P < 0·001) and was associated with greater intraoperative blood loss (WMD 1·58, 95% of c.i. 0·44 to 2·71 ml; P = 0·007). There were no differences between the two approaches in rate of conversion to open surgery, length of hospital stay, postoperative pain, adverse events, wound infections or port-site hernias. Better cosmetic outcomes were demonstrated in favour of SILC as measured by Body Image Scale questionnaire (WMD -0·97, 95% of c.i. -1·51 to -0·43; P < 0·001) and Cosmesis score (WMD -2·46, 95% of c.i. -2·95 to -1·97; P < 0·001), but this was based on comparison with procedures in which multiple and often large ports (10 mm) were used. CONCLUSION SILC has a higher procedure failure rate with more blood loss and takes longer than LC. No trial was adequately powered to assess safety.

The analysed end-points were the anastomotic leakage rate, overall morbidity and 30-day postoperative mortality. RESULTS Four studies were included involving 400 patients. The anastomotic leakage rate was 7.3% in the preservation group and 11.3% in the ligation group. There was no statistically significant difference between the groups (OR 0.72, 95% CI 0.11-4.76; P=0.73). Overall morbidity and 30-day postoperative mortality were not compared since these data were reported in only one study. CONCLUSION The meta-analysis did not show any advantage for preservation of the IMA during sigmoid colectomy for diverticular disease in terms of anastomotic leakage.

Abstract
The aim of the present study is to evaluate the effects induced by increasing concentrations of human recombinant growth hormone on T lymphocytes. Ten healthy volunteers and twelve subjects with symptomatic allergies were enrolled in the study. Peripheral blood mononuclear cells and purified T lymphocytes were cultured in the presence of graded concentrations of growth hormone. Following appropriate in vitro stimulations, the proportion of apoptotic T cells, the percentage of activated T lymphocyte subpopulations, the phytohemagglutinin responsiveness and the Th2 response were assessed by flow cytometry analysis. Moreover, in order to evaluate the phosphoinositol-3-kinase signaling pathway involvement, cells were also analyzed after treatment with LY294002. The treatment with different concentrations of growth hormone did not influence the activation pattern of un-stimulated T lymphocytes. On the contrary, growth hormone was able to modify the CD38/HLA-DR co-expression of T cells activated with phytohemoagglutinin. A different response was observed when samples obtained from healthy donors and from subjects with symptomatic allergies were analysed. Moreover, growth hormone treatment was able to increase the Th2 response in the samples obtained from healthy donors only. The results of the present study strongly support the hypothesis that growth hormone administration may play an important role in conditions of impaired/activated immune systems. The observation that growth hormone administration at high doses may reverse its effects and that it may promote a Th2-oriented response have significant clinical implications when considering the use of this hormone for artificially enhancing the physical performances of healthy athletes.

Abstract
Data on 2436 primary breast carcinomas diagnosed between 1992 and 2006 were collected to evaluate the rate of frozen section procedures performed over time. Frozen section procedures performed to evaluate resection margins for conservative surgery or sentinel node status were excluded. Over time, there was a decrease in the use of frozen sections indistinctly extended to all pT cancer categories. The rate of cancers diagnosed with frozen sections was 51.2% in 1999, and 0% in 2005-2006. In the same period, the adoption of cytology and core biopsy for breast cancer diagnosis increased from 40% in 1992 to more than 90% since 1999. In an audited diagnostic activity on breast pathology, the routine use of frozen sections on primary lesions was considered inappropriate, particularly in assessment of clinically non-palpable lesions, and should be limited to cases with inadequate pre-surgical sampling.

Abstract
Recent observations suggest an involvement of mast cells in Helicobacter pylori gastritis, but the mechanism of intraepithelial mast cell activation in H. pylori-infected patients remains to be clarified. Intraepithelial mast cells, identified by immunohistochemistry for CD117, were quantified in antral biopsies from 6 patients with H. pylori "active" chronic gastritis, 7 patients with H. pylori "nonactive" gastritis, and 9 controls. Antral biopsies from patients with H. pylori "active" gastritis showed higher intraepithelial mast cell counts than those from patients with H. pylori "nonactive" gastritis and from controls. Electron microscopy, selectively performed in 6 cases of H. pylori "active" gastritis, confirmed the presence of intraepithelial mast cells and allowed their subdivision into mature cells with intact electron-dense granules or degranulated cells. Other mast cells appeared to migrate through defects in the basement membrane into the epithelial layer. Mast cells in these areas often showed piecemeal degranulation or were characterized by large canaliculi, expanded Golgi areas, and a few granules, a process similar to the phase of recovery from anaphylactic degranulation of isolated human mast cells. The possible significance of these unusual ultrastructural findings is discussed.

Abstract
Tumour growth involves two essential deviations from the normal state including the induction of proliferative stimuli, and simultaneous suppression of potentially compensatory cell death. It has been suggested that the development of invasive cancer involves a progressive switch from predominantly apoptotic to necrotic tumour cell death. The presence of tumour necrosis in pathologic specimens may not only reflect tumour biology, but also provide additional beneficial prognostic information. This review emphasises the role of tumour necrosis as an additional prognostic factor for patients with certain types of epithelial neoplasms.

Abstract
A histological variant of gastric adenocarcinoma, characterized by an intense tumor-associated tissue eosinophilia (TATE), has been occasionally reported in the literature. The purpose of this ultrastructural study was to determine the interactions between frequently occurring eosinophils and tumor cells in gastric carcinoma characterized by TATE. Fresh tumor tissue of 92 gastric carcinomas was processed for both light and electron microscopic examination. Intense TATE was found in 7 out of 92 (7.6%) gastric carcinomas (6 of intestinal-type and 1 of diffuse-type). Electron microscopy, selectively performed in 7 cases with intense TATE, revealed eosinophils, singly or in groups, in contact with damaged or necrotic tumor cells. Activated eosinophils showing piecemeal degranulation were also found in intimate contact with viable tumor cells, characterized by plasma membrane caveolar invaginations. The authors regard this close morphological relationship as in vivo evidence for possible cross-talk between eosinophil and viable tumor cell, a conclusion that has already been drawn from experimental studies, but until now inadequately supported by ultrastructural observations in a human tumor.

Abstract
AIM Endothelial dysfunction has been recognized as the early event and the common feature of chronic disorders associated with increased risk for atherosclerotic heart diseases. While the beneficial effects of aerobic, moderate-intensity exercise on endothelial function are very well assessed, an intriguing doubt exists about the effects of long-term high-intensity physical activity. The aim of the present study was to compare recent findings of our group concerning homocysteine levels in athletes to available data in literature in order to clarify the meaning of such apparent metabolic paradox. METHODS The studied population included 185 athletes: 180 healthy age and sex matched subjects served as control group. The assessed variables included homocysteine, folate, vitamin B12, total and HDL cholesterol, LDH, CPK and IL-6. Results were compared to available data in literature. RESULTS The prevalence of hyperhomocysteinemia (>15 µmol/L) in athletes and controls was 55% and 15%, respectively. In the studied population, no correlation was found between homocysteine and all the other investigated variables. CONCLUSION The present results suggest that intensive physical training could induce a pathological increase of homocysteine levels. With this regard, it has been suggested that the observed increases of cardio-vascular risk factors in athletes could represent an adaptative feature marker of muscle demand but would not actually lead to endothelial damage. This remains, however, a speculative hypothesis and further analysis are needed in order to clarify the clinical significance of those observations in order to better preserve the athletes immediate and future health.

Abstract
Mitotic catastrophe is a common phenomenon occurring in tumor cells with impaired p53 function exposed to various cytotoxic and genotoxic agents. The defective p53 checkpoint causes improper segregation of chromosomes, resulting in aberrant mitosis, multiple micronuclei, multinucleate giant cells, and eventual necrosis-like death and centrosome aberration. Although various descriptions explaining mitotic catastrophe exist, there is still no generally accepted definition of this phenomenon. However, the syndrome of mitotic catastrophe may be a unifying morphological concept of particular interest to cancer research, as it integrally links cell death to checkpoints of the cell cycle. Morphological findings compatible with mitotic catastrophe may be found in pleomorphic, giant cell carcinomas--neoplasms characterized by a poor prognosis. The inclusion of mitotic catastrophe as part of the microscopic evaluation of tumors will add further insight to the pathobiology of tumor progression and in novel therapeutic designs. Finally, the possibility of assimilating mitotic catastrophe into a prognostic score is discussed.

Abstract
Verocytotoxin-producing Escherichia coli (VTEC) O26 is an emergent pathotype that has caused an increasing number of sporadic cases and outbreaks of gastroenteritis, hemorrhagic colitis, and hemolytic uremic syndrome in the United States and Europe. Many cases are associated with the consumption of milk and undercooked or fermented meats. The stx(2) strains of VTEC O26 seem to be more likely to cause human infections than isolates expressing only stx(1). The isolation and identification of VTEC O26 from foods is labor intensive and time-consuming. We developed a multiplex PCR (M-PCR) assay for the identification and characterization of E. coli O26 VTEC and its detection in raw milk and ground beef. The method is based on the amplification of the wzx, stx(1), and stx(2) genes for the simultaneous detection of the O26 antigen and verocytotoxin types 1 and 2. This M-PCR assay had a sensitivity of 10(8) CFU/ml when applied to a bacterial suspension and of 10(6) CFU/ml or g when applied to both inoculated milk and minced beef samples. This M-PCR assay also was highly specific, and results were consistently negative for negative controls (nonpathogenic E. coli strains, uninoculated milk and beef samples, and samples inoculated with the nontarget microorganisms). This method could be used for the rapid detection of E. coli O26 VTEC from foods and for the rapid identification and characterization of clinical and environmental isolates.

Abstract
The mitochondrial DNA of the cattle grub Hypoderma lineatum (de Villers) (Diptera: Oestridae) was completely sequenced. The entire molecule was 16,354 bp long and presented a heavy bias towards A + T, which accounted for 77.8% of the whole genome. Hypoderma lineatum genes were organized in the same order and orientation as in the mitochondrial genomes available for other species belonging to the Oestroidea superfamily and compared in this study [Chrysomya putoria (Wiedemann), Cochliomyia hominivorax (Coquerel), Lucilia sericata (Meigen) and Dermatobia hominis (L.)], except for the occurrence of a 102-bp non-coding region partially present in other species. The complete sequence of H. lineatum will represent a useful dataset to evaluate the evolutionary pattern of mtDNA within Oestroidea by using molecular information in diagnostic, taxonomic and evolutionary studies.

Abstract
BACKGROUND Perioperative heart failure (HF) in coronary operations is accompanied by a high operative mortality rate. An intra-aortic balloon pump (IABP) is often used to treat this syndrome. The correct timing for IABP insertion after completion of the operation has not yet been investigated. The aim of this study was to investigate the operative mortality in perioperative HF patients who had undergone coronary operations with respect to the early or the late use of IABP. METHODS This is a retrospective study including 7,270 patients who had undergone coronary surgery with or without associated procedures. A population of patients with perioperative HF was extracted and analyzed with respect to the use of drugs, intra-operative or post-operative IABP to treat this condition. RESULTS A total of 1,051 (14.5%) patients had perioperative HF. The mortality rate in this group was 13.5%. Early (intra-operative) IABP insertion was performed in 123 patients. In contrast, 928 patients were treated with inotropic drugs only, and, of these patients, 59 developed a drug-refractory HF requiring late IABP insertion. Operative mortality was significantly (P=0.001) higher in patients requiring late (64.4%) vs. early (41.5%) IABP insertion. Independent risk factors for developing a drug-refractory HF were age, pre-operative serum creatinine value and an associated mitral valve procedure. CONCLUSIONS Postponing the use of IABP may be deleterious in patients with drug-refractory HF. In the presence of the three factors independently associated with the risk of a drug-refractory HF, early IABP insertion is suggested.

Abstract
AIM Several randomized trials on conservative surgery compared with mastectomy in early-stage breast cancer have validated this technique in terms of local and distant relapse and survival of patients. Standard conservative approach includes surgical removal of the cancer with adequate cancer-free margins, axillary dissection, postoperative breast irradiation and adjuvant treatments when required. METHODS From 1987 to 2003, 500 early stage breast carcinoma were treated on 494 patients with conservative surgery and postoperative radiotherapy. Surgery consisted in a wide tumorectomy, with intraoperative control of R0 margins. The total postoperative radiation dosage was 50 Gy on the whole breast, associated with a boost of 10 Gy on tumor bed (20 Gy in T2 neoplasms). Before 1997 node-positive patients were treated with axillary irradiation with 50 Gy. Postoperative chemotherapy and/or hormonal therapy were administered to patients according with node-involvement, age and menopausal status. AJCC-stage was T1N0 in 44%, T2N0 in 15%, T1N1 in 19% and T2N1 in 22% of the patients. RESULTS In a postoperative setting, we observed 9% of axillary seromas or hematomas and 7% of oedema of the arm. At a median follow-up of 150 months (range 48-248 months), actuarial local recurrence rates were 7% at 5 years and 14% at 10 years. The actuarial rates of distant metastases were 18% at 5 years and 33% at 10 years. Ten-year overall and disease-free survival rates were 81% and 60%, respectively. Cosmetic results were good/excellent in 80%, satisfactory in 10% and poor in 10% of patients. CONCLUSION Recurrence and survival rates in breast-conserving surgery are consistent with indexed literature on conservative treatment of early breast cancer. Women eligible for conservative treatment should be offered the choice of either wide tumorectomy or quadrantectomy with axillary lymph nodes removal and postoperative radiotherapy, or modified radical mastectomy.

Abstract
AIM Rhodiola Rosea, is an adaptogen plant which has been reported to promote fatty acids utilisation, to ameliorate antioxidant function, and to improve body resistance to physical strenuous efforts. The purpose of the present study was to investigate the effects on physical performance as well as on the redox status of a chronic Rhodiola Rosea supplementation in a group of competitive athletes during endurance exercise. METHODS Following a chronic supplementation with Rhodiola Rosea for 4 weeks, 14 trained male athletes underwent a cardio-pulmonary exhaustion test and blood samples to evaluate their antioxidant status and other biochemical parameters. These data were compared with those coming from the same athletes after an intake of placebo. RESULTS The evaluation of physical performance parameters showed that HR Max, Borg Scale level, VO(2) max and duration of the test were essentially unaffected by Rhodiola Rosea assumption. On the contrary, Rhodiola Rosea intake reduced, in a statistically significative manner, plasma free fatty acids levels. No effect on blood glucose was found. Blood antioxidant status and inflammatory parameters resulted unaffected by Rhodiola Rosea supplementation. Blood lactate and plasma creatine kinase levels were found significantly lower (P<0.05) in Rhodiola Rosea treated subjects when compared to the placebo treated group. CONCLUSION Chronic Rhodiola Rosea supplementation is able to reduce both lactate levels and parameters of skeletal muscle damage after an exhaustive exercise session. Moreover this supplementation seems to ameliorate fatty acid consumption. Taken together those observation confirm that Rhodiola Rosea may increase the adaptogen ability to physical exercise.

Abstract
BACKGROUND Various nuclear envelope derivatives, such as the annulate lamellae, the intranuclear tubules as well as the nuclear projections and pockets may be observed electron microscopically in tumour cells. PATIENTS AND METHODS In a series of eight gastric adenocarcinomas, ultrastructural features of nuclear envelope changes were analyzed and correlated to the biology of the tumours. RESULTS Histologically, three tumours were intestinal-type adenocarcinomas and showed annulate lamellae in the cytoplasm of some tumor cells. Five tumors were mixed-type adenocarcinomas, with a solid growth pattern; two of these tumours were characterized by the presence of intranuclear tubules, whereas the remaining three tumours exhibited nuclear pockets and projections. Seven out of eight patients died due to metastatic disease during the follow-up period (median 31 months). CONCLUSION Ultrastructural evaluation of pleomorphism of the nuclear envelope may be an ancillary method for the pathologist in the study of nuclear grading of gastric carcinomas.

Abstract
Granuloma is a focal, compact collection of inflammatory cells in which mononuclear phagocytes predominate. The authors report 9 cases of papillary-tubular gastric adenocarcinomas characterized by mature granulomas associated with recent microhemorrhages. Mature granulomas were composed of foamy, CD68-positive histiocytes with occasional giant cells. Hemosiderin-containing macrophages were present in the tumor stroma, suggesting phagocytosis of erythrocytes. Under electron microscopy, mature (nonepithelioid) granulomas and clusters containing 1 macrophage and 1-3 eosinophils were found. This study provides morphological examples of skewed type II macrophage infiltration in gastric adenocarcinomas that is involved in scavenging activity, particularly erythrophagocytosis, formation of mature (nonepithelioid granulomas), and heterotypic aggregation with eosinophils.

Abstract
BACKGROUND Subclinical hyperthyroidism (sHT) affects cardiovascular (CV) morphology and function; whether such changes can impact on sport eligibility is unclear. AIM This exploratory study evaluated the CV system and sport eligibility in athletes with levothyroxine-induced sHT, in the setting of mandatory pre-participation screening. SUBJECTS AND METHODS A full, non-invasive CV screening (history and physical examination, 12-lead ECG, echocardiography, 24-hour Holter ECG, exercise stress test) was performed in two groups of untrained female athletes affected by non-toxic multinodular goiter. One group was taking levothyroxine at mildly suppressive doses (TG) whereas the other was untreated (UG). There was also a group of healthy controls (HC). RESULTS In TG the following characteristics were observed: a) a higher resting heart rate (HR; p<0.01 and p<0.05, vs HC and UG respectively), b) a thicker left ventricular posterior wall (p<0.05 vs HC, and p<0.05 vs HC and UG, respectively), c) a higher mean HR during the 24-hour Holter ECG (p<0.01 and p<0.05, vs HC and UG respectively), and d) a lower achieved maximum work load (p<0.05, vs HC). No differences in the prevalence of cardiac arrhythmias among groups were observed. Sport eligibility was granted to all except one subject in the TG. CONCLUSIONS Although some alterations were found in athletes with levothyroxine-induced mild sHT, these are probably of limited clinical relevance and they did not contraindicate sport participation in the majority of cases. Future research to address both health risks and the need for specific evaluations (e.g. free thyroxine, TSH, echocardiography) during the preparticipation screening of athletes with sHT is warranted.

Abstract
Herpes simplex virus (HSV) infection is one of the most common sexually transmitted viral diseases worldwide. HSV type 2 causes most genital herpes and HSV type 1 is usually transmitted via non-sexual contacts. We studied 109 pregnant women between January 2007 and December 2008, in relation to their age, condom use, number of sexual partners, age at first intercourse, parity and smoking habits. The aim of this study is to evaluate the prevalence of HSV cervical infection and HSV co-infection with other genital microorganisms associated with poor neonatal outcome. Our results show that of the 109 outpatients enrolled, 30% were HSV1 and/or HSV2 positive, of whom 30% were infected with both HSV1 and HSV2, 18% were infected with HSV1 alone and 52% with HSV2 alone. A significant association between HSV1 and HSV2 infection was found, and the prevalence of HSV2 infection in women infected with HSV1 was 63%. The prevalence of HSV1/2 varied in the presence of other vaginal microorganisms but a statistical significant association was not found. This pilot study is probably too small to obtain statistically significant results. Nevertheless, using these observed results, we calculated that about 530 patients with comparable features should be enrolled to detect an increase of 50% in HSV infection due to the presence of other genital infections and potential risk factors.

Abstract
Recruitment and activation of eosinophils have been studied intensely in asthma and other allergic diseases. Less is known about the infiltration and degranulation patterns of eosinophils in the tumor stroma. Seven cases of advanced gastric carcinomas were found to be massively infiltrated by eosinophils and studied by light and electron microscopy. Gastric carcinomas, despite having similar numbers of tissue eosinophils, exhibited markedly different degranulation patterns. In 2 cases, resting nondegranulating eosinophils were found. Piecemeal degranulation was the predominant mode of secretion from eosinophils localized within the tumor stroma in 4 cases. Eosinophil exocytosis and cytolysis were rarely observed. In 1 case, crystals morphologically similar to Charcot-Leyden crystals were observed at the extracellular level as well as in phagosomes of tissue macrophages, confirming active sequestrations of eosinophil Charcot-Leyden protein by macrophages in vivo. In the same case, eosinophils showed characteristic features of early and late apoptotic changes, such as condensed chromatin, focal dilatation of nuclear envelope, and preserved plasma membrane. Morphological association between apoptotic eosinophils and deposition of granules in the tumor stroma was found. Extracellular deposition of intact granules from apoptotic eosinophils was distinct from eosinophilic (necrotic) cytolysis, and has reported previously in experimental studies in vitro. To the knowledge of the authors, this case represents the first report of late apoptotic eosinophils that release their granules within the tumor stroma in a human gastric carcinoma.

Abstract
Osteoporosis is a multifactorial progressive skeletal disorder characterized by compromised bone mass which predisposes to increased fracture risk. Fractures are often associated with increased morbidity, mortality, loss of function, deformity and functional limitations. The major public health impact of osteoporosis calls for organized strategies for both primary and secondary prevention. Even if pharmacological therapeutic interventions provide substantial reduction in fracture risk, prevention of osteoporosis should begin early in life. Primary prevention during growth and adolescence aims to obtain a high peak bone mass, adequate calcium intake, exercise and early diagnosis and treatment of potential skeletal deformities. Secondary prevention, during middle age, aims to identify the subjects with low bone mass and more than one risk factor for an osteoporotic fracture, in order to plan multifactorial interventions with a special emphasis on nutritional aspects and individualized sport therapy.

Abstract
The cases of two patients with hyperthyroidism and acute left ventricular (LV) dysfunction with segmental wall motion abnormalities resulting in heart failure are reported. Both had electrocardiographic changes mimicking ischemic coronary artery disease. Treatment with antithyroid medications, beta blockers, and angiotensin-converting enzyme inhibitors rapidly restored LV function. The rapid reversibility suggests a role for myocardial stunning, an important entity to recognize in hyperthyroidism since this form of LV dysfunction can be reversed with appropriate treatment.

Abstract
Automated haematological analysers still represent the gold standard for the study of reticulocyte maturation even if this technique is based on structural properties and staining affinity rather than on functional aspects. On the contrary, flow cytometry allows the simultaneous analysis of multiple cellular characteristics including functional features. Aim was to investigate whether simultaneous analysis of different reticulocyte parameters using flow cytometry may add functional information when considering their pattern of maturation. Thirty-nine healthy donors (H) and 31 haemodialysed patients on treatment with rHuEpo (HDT) were analysed. Reticulocyte counts and their stages of maturation were studied both with ADVIA 2120 and by flow cytometry. TO/CD71 scattergraph reticulocyte analysis designed a peculiar distribution which was similar among the same group of subjects (H or HDT), but different between H and HDT. distribution of the percentage of reticulocytes in low, medium and high boxes calculated by ADVIA 2120 did not show any difference between H and HDT groups, while the analysis using flow cytometry pointed out statistically significant differences between H and HDT groups in the three boxes where the TO+/CD71+ reticulocytes were localized. The present study suggests that TO/CD71 analysis was reproducible and could detect different pattern of maturation of a particular clinical setting.

Abstract
Recently the awareness had progressively strengthened that the main interest of health care organizations is effectiveness and appropriateness of clinical performance. They have a statutory duty to seek quality improvement through clinical governance. All health care operators are involved in clinical governance implementation, in respect of their organizational positions toward continuous quality improvement. In this way health care organizations, professionals and patients will benefit of outcomes of the change.

Abstract
BACKGROUND Angiogenesis requires complex multistep signalling pathways and a high degree of spatial and temporal coordination among endothelial cells and pericytes. The two cell types exhibit numerous contacts in vivo and in vitro, including the occurrence of peg-socket junctions. MATERIALS AND METHODS Ultrastructural findings in 9 cases of advanced gastric carcinomas were reviewed with special emphasis on endothelium/pericyte peg-socket junctions. RESULTS The incidence of peg-socket junctions was approximately 8% in 5 out of 9 cases. The remaining 4 cases showed a very low rate, including two cases in whom interactions were totally absent. Peg-socket junctions consisted of cytoplasmic projection from the pericyte protruding into the endothelial indentation. The endothelial cells interacting with pericytes showed ultrastructural signs of partial stabilization such as continuous endothelial lining, regularly constructed interendothelial junctions, more or less integrated pericytes, and multilayered basement membrane. CONCLUSION Our ultrastructural study confirms previous reports regarding pericyte/endothelial peg-socket interdigitations in murine and human granulation tissues and extends these findings to the microvasculature of human gastric carcinomas.
