Abstract
We report the case of a 70-year-old man with symptoms of urinary obstruction and haematuria, with histological diagnosis of primary signet-ring cell carcinoma of the prostate. Almost 90% of the tumour cells contained characteristic intracytoplasmic vacuoles that positively stained with diastase-digested PAS, Alcian blue and mucicarmine. The positive immunostaining for PSA and PSAP confirmed the prostatic origin of the tumour. Although the patient received hormonal therapy, the disease progressed and the patient died 11 months after surgery.

Abstract
Bronchogenic cyst is a congenital anomaly of the primitive foregut. Unusual occurrences in extrathoracic sites have been described in the literature, some of which may clinically simulate neoplasms. We report three additional cases arising near the left adrenal gland, left ovary and gastric wall. Pathological findings are discussed, together with a review of the literature.

Abstract
Effective disease management after an acute coronary event is essential, but infrequently implemented, due to challenges around the research evidence and its translation. Policy-makers, health professionals and researchers are confronted by the need for increased services, to improve access and equity, but often with finite and reducing resources. There is a clear need to develop innovative ways of delivering ongoing preventative care to the vast and increasing population with coronary disease. However, translation into clinical practice is becoming increasingly difficult while the volume of trial and review evidence of disparate models of delivery expands. Indeed, the prevention literature has evolved into a complex web of differing models offered to diverse patient populations in an array of settings. We describe a united organisation of care that aims to facilitate coordinated secondary prevention for all in need (SPAN). SPAN is inherently flexible yet provides a minimum level of health service standardisation. It can be delivered across any area health service regardless of a patient's age, gender, ethnicity, geographical location, or socioeconomic status. Importantly, the setting, communication technologies and components of each patient's care are governed and woven into continuing care provided by the family physician in concert with a cardiac care facilitator.

Abstract
Renal cell carcinoma is the sixth leading cause of death for cancer in industrialized countries and one third of patients has metastases at the time of diagnosis. The three most common histological types of renal cell carcinoma are: clear cell carcinoma (70-80%), papillary carcinoma (10-15%) and chromophobe cell carcinoma (5%). The location of metastases vary according to histotype: lung metastases are found in 53.6% of cases in patients with clear cell carcinoma, whereas in patients with papillary carcinoma or chromophobe cell carcinoma in 33.3% and 28.2% of cases, respectively. In contrast, chromophobe cell carcinoma is more often associated with liver metastases (33.3%), compared with clear cell carcinoma (9.7%) or papillary carcinoma (18%). Patients with renal cell carcinoma metastatic to a single organ have a better prognosis than patients with metastases in multiple organs and the overall survival of patients with localized lung metastases is similar to that of patients with exclusive bone metastases. The overall survival, therefore, is related more to the number of organs involved by metastasis rather than by the location of metastases. The widespread use of abdominal non-invasive diagnostic procedures, with an incidental finding of renal cell carcinomas still in a low stage of development, and the refinement of surgical techniques for resection of metastatic disease (metastasectomy) have led to only a slight improvement in overall survival in the last 30 years for the resistance of the tumor to common chemo-radiotherapy. Surgery remains the best therapeutic option and a rising in cutting-edge molecular therapies is strongly needed.

Abstract
Tracheal atresia is an uncommon congenital malformation with a high mortality rate. Clinical symptoms occur suddenly after birth. The diagnosis is suspected in any infant in whom improved ventilation is obtained despite aggressive attempts at resuscitation. We describe a small gestational week 34 male newborn affected by tracheal atresia without esophageal fistula with associated fetal growth restriction, ascites and polyhydramnios. Post mortem examination revealed a diffuse cyanotic status, abdominal ascites and a low birth weight. A 3 cm tract of trachea was documented that distantly ended in a blind pouch and without tracheoesophageal fistulae and enlarged bulky lungs connected to each other by a common thin-walled bronchus. Histological examination showed a normal conformed larynx and scratchily cartilaginous disks in the proximal tract of the short trachea. Vascular space referred to small arteries and veins, thin bands of fibrous tissue and adipose tissue were detected under the blind pouch. Lung distal airspaces were lined by premature cubic epithelium separated by a broad poorly vascularized interstitium. A striking interstitial and alveolar edema was remarkable.

Abstract
BACKGROUND Few studies have been carried out to date that have addressed the epidemiology of extranodal marginal zone lymphomas (EN-MZLs). PATIENTS AND METHODS We carried out a population-based study to investigate incidence rates (IRs) and time trends of EN-MZL diagnosed in the province of Modena (Italy) from 1997 to 2007. RESULTS One hundred and sixty-five cases were identified from the Modena Cancer Registry that corresponded to an age-standardized IR of 2.3 cases per 100 000. A bimodal distribution of age was shown with the group of young patients mostly represented by males with cutaneous lymphoma. No time trends were observed for the IR; the incidence of gastric mucosa-associated lymphoid tissue (g-MALT) lymphomas (N = 51) markedly declined during the study period, dropping from 1.4 in 1997 to 0.2 in 2002 and then remaining stable until 2007; the calculated annual percent change for g-MALT was -17.0% (95% confidence interval -26.6% to -6.2%). We also observed a significant decrease in the rate of g-MALT associated with Helicobacter pylori (HP) infection from 61% to 17% of patients diagnosed before and after 2002 (P = 0.007; P for trend = 0.016). CONCLUSION This population-based study provides new insights into recent changes in the epidemiology of EN-MZL, mainly represented by the sharp reduced incidence of HP-positive g-MALT lymphomas.

Abstract
We present a case of intraparenchymatous capillary-type hemangioma of the testicle in an adult. The patient was a 37-year-old man who showed a rapidly enlarging and palpable mass in left testicle. Radical orchiectomy was performed, and histological examination revealed an unencapsulated lobulated tumour with wide hemorrhagic portions. To our knowledge, the occurrence of rapid enlargement in a testicular hemangioma has not been previously reported, which might be explained by the development of intra-tumoural haemorrhage.

Abstract
PURPOSE This study evaluated the sensitivity of a 3.0-Tesla (T) magnetic resonance imaging (MRI) in measuring cerebral phenylalanine using proton magnetic resonance spectroscopy and in assessing MR-documented white-matter changes by means of diffusion studies (diffusion-weighted imaging, apparent diffusion coefficient map; diffusion tensor imaging) in patients with phenylketonuria. MATERIALS AND METHODS Thirty-two patients with the classical clinical and biochemical deficits of phenylketonuria underwent biochemical (blood phenylalanine), genotypic (phenylalanine hydroxylase gene) and radiological investigation by means of MRI, proton magnetic resonance spectroscopy and diffusion magnetic resonance imaging with a 3.0-T scanner. RESULTS Periventricular and subcortical white-matter changes were detected on all MR scans. In 29/32 patients, proton magnetic resonance spectroscopy easily documented abnormal signal elevation at 7.36 ppm, corresponding to phenylalanine, despite its low concentration. Phenylalanine signal amplitude relative to the creatine/phosphocreatine signal increased linearly with blood phenylalanine values (r 0.7067; p<0.001). Diffusion MRI demonstrated hyperintensity in the areas exhibiting MRI changes as well as decreased apparent diffusion coefficient values, but fractional anisotropy indices were normal. CONCLUSIONS The high signal, together with better spectral, spatial, contrast and temporal resolution, makes the 3.0-T MR the most suitable technique in the study of the phenylketonuria. In particular, the multimodal approach with MRI, proton magnetic resonance spectroscopy and diffusion magnetic resonance imaging can provide more information than previous studies performed with low-field systems.

Abstract
BACKGROUND Cetuximab improves activity of chemotherapy in metastatic colorectal cancer (mCRC). Gene copy number (GCN) of epidermal growth factor receptor (EGFR) has been suggested to be a predictive factor of response to cetuximab in patients (pts) with mCRC; on the contrary, K-ras mutation has been associated with cetuximab resistance. PATIENTS AND METHODS We have conducted a phase II study with cetuximab administered weekly for 3 weeks as single agent and then with 5-fluorouracil and radiation therapy as neo-adjuvant treatment for locally advanced rectal cancer (LARC). EGFR immunohistochemistry expression, EGFR GCN and K-ras mutation were evaluated on diagnostic tumor biopsy. Dworak's tumor regression grade (TRG) was evaluated on surgical specimens. RESULTS Forty pts have been treated; 39 pts are assessable. TRG 3 and 4 were achieved in nine (23.1%) and three pts (7.7%) respectively; TRG 3-4 rate was 55% and 5.3% in case of high and low GCN, respectively (P 0.0016). Pts with K-ras mutated tumors had lower rate of high TRG: 11% versus 36.7% (P 0.12). In pts with wild-type K-ras, TRG 3-4 rate was 58.8% versus 7.7% in case of high or low GCN, respectively (P 0.0012). CONCLUSIONS In pts with LARC, EGFR GCN is predictive of high TRG to cetuximab plus 5-FU radiotherapy. Moreover, our data suggest that a wild-type K-ras associated with a high EGFR GCN can predict sensitivity to cetuximab-based treatment.

Abstract
Ever since the introduction of magnetic resonance (MR), imaging with 1.5 Tesla (T) has been considered the gold standard for the study of all areas of the body. Until not long ago, higher-field MR equipment was exclusively employed for research, not for clinical use. More recently, the introduction of 3.0-T MR machines for new and more sophisticated clinical applications has resulted in important benefits, especially in neuroradiology. Indeed, their high gradient power and field intensity (3.0 T) allow adjunctive and more advanced diagnostic methodologies to be performed with excellent resolution in a fraction of the acquisition time required with earlier machines. The purpose of this paper is to illustrate the distinctive semeiological characteristics of 3.0-T morphological and angiographic brain imaging compared with lower-field systems and highlight the respective advantages and drawbacks based on the experience gained in the first 5 years from the installation of a 3.0-T magnet.
