Abstract
OBJECTIVES To demonstrate the potential role of transrectal ultrasound (TRUS) as a tool for diagnosis or recurrence detection in bladder cancer. MATERIAL AND METHODS We report two cases of a primary lesion of bladder neck and trigone misdiagnosed by conventional sonographic abdominal evaluation and a case of bladder cancer recurrence diagnosed by TRUS performed before cystoscopy. RESULTS The first patient presented at the Emergency Room of our Hospital for a flank pain with concurrent haematuria. The abdominal ultrasonography showed a right hydronephrosis and a thickened bladder wall without endoluminal projections. The end-fire probe with a longitudinal approach clearly showed a thickening of the bladder wall extended from the bladder neck to the posterior area. The patient was submitted to a transrectal prostate biopsy and to a urethrocystoscopy with a transurethral resection. The second patient was admitted to the Urology Unit for haematuria. Abdominal ultrasonography was unremarkable and urine cytology negative. The TRUS with an end-fire probe showed a 5 mm area of irregular thickening of the mucosa at the bladder neck. The uretrocystoscopy confirmed the presence of a perimeatal papillary lesion. CONCLUSION We recommend the use of TRUS for bladder cancer detection in selected patients, as an easy, accurate and inexpensive tool. We need further study to validate the role of TRUS in the diagnosis and follow-up of bladder urothelial carcinoma.

Abstract
We investigated global methylation and histone acetylation in 50 conventional clear cell renal carcinomas (RCC), treated with radical nephrectomy, to assess their possible role as diagnostic biomarkers. The features considered in this study were patient age, tumor size and grade, percentage and intensity of 5-methylcytosine (5mc) and Acetyl-Histone (Lys 9) expression in tumor tissue. All considered parameters were correlated with patient specific survival. The mean percentage of global cellular methylation in tumoral tissue was significantly higher compared to normal peritumoral tissue (p<0.0001), while the intensity of cellular methylation was significantly higher in normal tissue than in tumoral tissue (p=0.001). The mean percentage of histone cellular acetylation in tumoral tissue was significantly lower compared to normal peritumoral tissue (p=0.0005), while the intensity of mean acetylation in neoplastic tissue was similar to the normal tissue. The percentage of global DNA methylation was significantly higher in grades 3 and 4 tumors (p=0.033). Global DNA methylation and histone acetylation in tumoral tissue did not correlate with survival. Fuhrman grade was statistically significant for prognosis (p=0.031). In conclusion, global hypermethylation and histone hypoacetylation play an important role in RCC carcinogenesis; Fuhrman grade is still considered the most important factor for patient survival; 5mc can have a role as markers of aggressiveness.

Abstract
AIMS To evaluate the expression of transient receptor potential vanilloid type-1 channel protein (TRPV1) in normal and neoplastic urothelial tissues and to correlate TRPV1 expression with clinicopathological parameters and disease-specific survival. METHODS AND RESULTS TRPV1 expression was analysed in normal and neoplastic urothelial samples at both mRNA and protein levels by quantitative real time polymerase chain reaction (qPCR) and immunohistochemistry, respectively. TRPV1 downregulation was found in urothelial cancer (UC) specimens, which correlated with tumour progression. Moreover, TRPV1 mRNA levels were associated with clinicopathological parameters to assess the role of TRPV1 downregulation as a negative prognostic factor for survival. Kaplan-Meier survival analysis demonstrated a significantly shorter survival in patients showing TRPV1 mRNA downregulation. Multivariate Cox regression analysis indicated further that TRPV1 mRNA expression retained its significance as an independent risk factor. CONCLUSIONS The progression of UC of human bladder is associated with a marked decrease in TRPV1 expression, with a progressive loss in high-grade muscle invasive UC. Downregulation of TRPV1 mRNA expression may represent an independent negative prognostic factor for bladder cancer patients.

Abstract
Angiogenesis is a critical step in the growth, invasive progression and metastatic spread of solid tumors. We investigated the importance of tumor necrosis, and microvessel density (MVD), vascular endothelial growth factor (VEGF) and hypoxia inducible factor 1alpha (HIF-1alpha) immunohistochemical expression in a large series of clear cell renal carcinomas treated with radical nephrectomy and assessed the prognostic value of their expression in terms of patient survival at long-term followup. Fifty patients with clear cell RCC were examined. The features considered when evaluating the patients were age, tumor size and grade, intratumoral vascular and renal capsula invasion, histological necrosis, and MVD, vascular and tumoral cell VEGF, and vascular, tumoral cytoplasmic and nuclear HIF-1alpha expression on the histologic specimens. All considered parameters were correlated with patient specific survival. Mean age was 62.06 +/- 6.8 years. Median follow-up was 191.66 months; median survival was 120.86 months. Twenty-one patients developed metastases in the follow-up. Tumor necrosis, microvascular invasion and renal capsula infiltration are more likely to occur in high stage and grade RCC; cytoplasmic HIF-1alpha is highly expressed in high grade RCC. Survival is dependent upon tumor stage and grade, the presence of intratumoral vascular invasion and capsular infiltration, and tumor necrosis; MVD also resulted as being an important prognostic factor. VEGF and HIF-1alpha correlate with prognosis in high stage tumors where VEGF is the most important independent prognostic factor for cancer specific death. The histological and immunohistochemical parameters considered in our study can influence disease recurrence and survival in RCC.

Abstract
Surgery is the main treatment for renal cell carcinoma (RCC); nephron sparing surgery can be performed as a treatment of choice for small peripheral lesions. Epigenetics configures a new entity that regulates gene expression throughout methylation, acetylation and chromatin remodelling. In addition to silencing as a result of mutations, loss of heterozygosity, or classic genetic events, epigenetic modification symbolizes essential events during carcinogenesis and tumour development. We investigated global methylation and histone acetylation expression in a series of small conventional clear cell renal carcinomas (i.e. less than 5 cm) (pT1a) treated with partial nephrectomy, to assess their possible role as diagnostic biomarkers. A total of 54 patients with conventional single RCC were selected and treated with partial nephrectomy; they were followed up to 186 months. Immunohistochemistry was performed on paraffin-embedded sections, using anti-5-methylcytosine (5mc) and anti-Acetyl-Histone H3 (Lys 9). Our results confirm that the mean percentage of global cellular methylation in tumoural tissue was significantly higher compared to healthy peritumoural tissue, whereas the mean percentage of histone cellular acetylation in tumoural tissue was significantly lower. The percentage of methylation was significantly higher in grades 3 and 4 (P = 0.033), whereas the percentage of histone acetylation was significantly lower (P = 0.023), suggesting therefore that these markers could correlate with tumour aggressiveness in pT1a RCC. On univariate analysis of patient survival in relation to the different considered factors, Fuhrman grade was the most important survival factor. These epigenetic markers can give us interesting information about chromatin remodelling in RCCs; the percentage of global methylation increases with increasing Fuhrman grade, whereas histone acetylation decreases with increasing grade in small RCC; our results suggest that global hypermethylation and histone hypoacetylation can be assumed to be an early event in RCC and to correlate with tumour aggressiveness.

Abstract
OBJECTIVE To determine the expression of HECA-452 epitope in mycosis fungoides (MF), assess whether its expression increases in relapsed MF compared with nonrelapsed MF and determine the potential prognostic relevance of HECA-452 expression. STUDY DESIGN HECA-452 expression was evaluated by immunohistochemistry in a consecutive series of 20 MF. In all patients we evaluated the disease-free survival rate according to HECA-452 expression in a univariate analysis. RESULTS We found a low expression in 5 MF (25%), a moderate expression in 8 MF (40%) and a high expression in 7 MF (35%) in the intraepidermal area. All patients were disease-free after appropriate therapy. Four of 20 patients (20%) relapsed within 2 years. HECA-452 expression significantly correlated with disease relapse in these patients. In fact, among the 7 patients whose lesions had a high expression, 4 had a disease recurrence (57%), whereas 0 of 13 (0%) with a low or moderate expression relapsed (p < 0.05). CONCLUSION HECA-452 expression correlates with disease relapse in MF. Correlation with disease progression suggests that HECA-452 could be of prognostic relevance in the early stage of mycosis fungoides.

Abstract
The aim of our study is to investigate the effects of chronic sacral neuromodulation on Nitric Oxide (NO) metabolism in the rat bladder. 26 female Sprangue-Dawley rats were considered: group I, normal control rats; group II, a sham treatment, in whom catheters for electrical stimulation were placed in the S1 foramen bilaterally and left in place for 21 days, without performing neuromodulation; group III in whom electrical sacral neuromodulation was performed for 21 days. Finally a cystectomy was performed and the bladder biopsy specimens were sent for immunostaining with n-NOS and i-NOS. Morphological and immunohistochemical analysis was carried out, and evaluated in urothelial cells, endothelial cells and muscle fibers of the muscularis propria. Differences between the 3 groups were analyzed by Student Newman-Keuls test. We could observe that urothelial and endothelial i-NOS (37.00±4.69 and 59.00±7.42 respectively) and urothelial n-NOS (36.80±7.85) expression are significantly increased in neuromodulated rats, compared to groups 1 and 2 (p < 0.005). In conclusion, the increase of i-NOS expression on endothelial cells after sacral neuromodulation could be in some way related to angiogenetic responses in the microvascular structures; the increase of n-NOS and i-NOS expression on urothelial cells can suggest that NO is able to influence the plasticity of bladder response, inducing the release of messengers within the urothelium. This study can therefore improve our understanding of the mechanisms of sacral neuromodulation on chronic bladder dysfunction; further studies will need to better demonstrate the role of angiogenesis in the bladder after sacral neuromodulation and to investigate the effects of neuromodulation in rats with chronically induced bladder dysfunction.

Abstract
INTRODUCTION Surgical site infections are the second most common cause of nosocomial infections and, typically, gram-positive pathogens are involved. MATERIALS AND METHODS A mouse model was used to investigate the efficacy of different methods for the treatment of wound infections. A full thickness wound was established on the back subcutaneous tissue of adult male BALB/c mice. A small gauze was placed over each wound and then inoculated with 5 x 10(7) colony-forming units of Staphylococcus aureus. The study included a control group that did not receive any treatment and four contaminated groups treated, respectively, with: (1) drug-free Allevyn (Smith and Nephew Healthcare, Yorkshire, United Kingdom), (2) teicoplanin-soaked Allevyn, (3) drug-free Allevyn and daily intraperitoneal teicoplanin (7 mg/kg) and, finally, (4) teicoplanin-soaked Allevyn and daily intraperitoneal teicoplanin (7 mg/kg). Main outcome measures were quantitative bacterial culture, assessment of vascular endothelial growth factor (VEGF) plasma levels, histological examination with assessment of microvessel density, and of VEGF expression in tissue sections. RESULTS Data analysis showed that strong inhibition of bacterial growth was achieved in any group treated with intraperitoneal teicoplanin. However, the highest inhibition of bacterial growth was obtained in the group that received teicoplanin-soaked Allevyn and intraperitoneal teicoplanin. Histological examination showed that each treatment modality was able to reduce the delay in wound repair. The most effective treatment appeared to be the local application of teicoplanin-soaked hydro gel foam. The tissue effects were associated with an increase in neovascularization and VEGF expression by endothelial cells and fibroblasts in the granulation tissue. Bacterial colonies also were reduced, especially when teicoplanin was given parenterally. CONCLUSIONS Soaking a hydro cellular foam with an antistaphylococcal agents, such as teicoplanin, may be useful for the management of infected wounds.

Abstract
UNLABELLED Primary hypothyroidism is one of the most frequent complications observed in patients suffering from thalassemia. We investigated thyroid function in a group of patients attending the Pediatric Department of Cardarelli Hospital in order to determine in how many patients thyroid function worsened during a 12 year-period of follow up. PATIENTS AND MEASUREMENTS Fifty patients with beta-thalassemia major (27 females and 23 males), mean age 25.7+/-1.4 years, were re-evaluated according to the criteria of Faglia et al. Thyroid dysfunction was defined as follows: overt hypothyroidism (low FT4 and increased TSH levels >10 microU/ml); compensated hypothyroidism (normal FT4, TSH 5-10 microU/ml, and abnormal TRH test); subclinical hypothyroidism (normal FT4, basal TSH 0-5 microU/ml, abnormal TRH test). Correlation with hematological, biochemical and growth parameters was evaluated. RESULTS Ten out of 50 patients evaluated in a previous study had moved to other centers, and four patients had died from cardiac problems. Thus, 36 patients completed a 12 year-period of follow-up. In 25% of the patients the degree of thyroid dysfunction worsened with different degrees of severity. The prevalence of overt hypothyroidism had risen to 13.9% from 8.4%. No cases of secondary hypothyroidism were observed, and anti-thyroglobulin and anti-thyroperoxidase (TPO) antibody titers were negative in all patients. Five (28%) out of 17 patients with normal thyroid function previously (one female, four male) showed an exaggerated TSH response to a TRH test, with normal serum levels of FT4, and they were classified as having subclinical hypothyroidism; while another patient died of cardiac complications. Four out of twelve patients with previous subclinical hypothyroidism showed worsening with a different degree of severity: two females changed to compensated hypothyroidism, and two males to overt hypothyroidism. Furthermore, two out of six patients with compensated hypothyroidism and one out of four patients with overt hypothyroidism died of cardiac failure. In all patients there was no correlation between serum ferritin levels, blood transfusion, pretransfusion Hb levels and worsening of thyroid function. Echographic data showed features of dishomogeneity of the parenchyma with different degrees of severity in accordance with the criteria of Sostre and Reyes. The highest score was observed in all patients with overt and compensated hypothyroidism. CONCLUSIONS A slow worsening of thyroid function was observed in 25% of the studied patients and only two of them developed overt hypothyroidism. The echographic pattern seems to be strongly predictive of thyroid dysfunction.

Abstract
OBJECTIVE To evaluate Cdc42 expression in eutopic and ectopic endometrial tissue in patients with adenomyosis and ovarian endometriotic cysts compared with patients without endometriosis. DESIGN Experimental retrospective study. SETTING University hospital. PATIENT(S) Twenty-four patients with adenomyosis, 19 with ovarian endometriomata, and 9 with fibroids or benign ovarian cysts. INTERVENTION(S) Hysterectomy and bilateral oophorectomy. MAIN OUTCOME MEASURE(S) Immunostaining for Cdc42 of eutopic and ectopic endometrial tissues. RESULT(S) In eutopic endometrium of patients with adenomyosis and with fibroids or benign ovarian cysts, the intensity of Cdc42 immunostaining was weaker, especially in the specialized stromal cells, compared with cases with ovarian endometriosis (chi(2) test, P=.003). Expression of Cdc42 in eutopic endometrium showed a trend to be higher in the secretory than in the proliferative phase and in patients with ovarian endometriotic cysts compared with patients with adenomyosis (unpaired t test, P=.005), especially in the proliferative phase. CONCLUSION(S) An abnormally high expression of Cdc42 in eutopic endometrium in the secretory phase may contribute to the development of ovarian endometriosis, but it does not seem to be involved in the pathogenesis of adenomyosis.

Abstract
Myeloid sarcoma (MS) is a malignant tumour of myeloblasts rarely occurring in the maxillary bone. The tumour may precede or be concurrent with leukaemic infiltration of the bone marrow or herald blastic transformation of a myelodysplastic syndrome or a chronic myeloproliferative disorder. Myeloid sarcoma is uncommon in the oral cavity, but it can involve the palate, gingiva, extraction socket, and cheek. Recognition and diagnosis of myeloid sarcoma involving the soft tissues of the oral cavity in an otherwise asymptomatic patient is important and mandates an appropriate haematological diagnostic workup. We herein report on a new case without any evidence of haematological disorders. We discuss the pathological diagnosis and the therapeutical approaches.

Eur J Cancer 2006; 42:1181-7. [PMID: 16644201 DOI: 10.1016/j.ejca.2006.01.043] [Citation(s) in RCA: 57] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2005] [Revised: 01/12/2006] [Accepted: 01/16/2006] [Indexed: 01/24/2023]
Abstract
Aim of this study was to investigate using immunohistochemistry techniques the interrelation between T immunoreactive cells and the expression of CCR10 and its ligand CCL27 in 59 cutaneous melanocytic lesions. In malignant melanomas, T lymphocyte density was significantly decreased from thin melanomas to intermediate and thick ones (P<0.0005). CCR10 expression was found both in benign and malignant lesions and it was directly correlated with the Breslow depth (P=0.0298) and inversely with T lymphocyte density (P=0.0231). Moreover, cases with positive sentinel lymph node tended to have a higher CCR10 expression compared to cases with negative sentinel lymph node (P=0.0281). When CCR10 and CCL27 expression were evaluated together, CCR10-/CCL27-melanomas tended to have a higher mean density of CD3+ and CD8+ lymphocytes. Our results suggest that in human melanomas CCR10 and CCL27 may act to increase the ability of neoplastic cells to grow, invade tissue, disseminate to lymph nodes and to escape the host immune response.
