Article: Bone Metastases Radiopharmaceuticals: An Overview.
[show abstract] [hide abstract]
ABSTRACT: The skeleton is one of the preferential sites for metastases of solid tumors, and metastatic disease is the most common malignancy of the bone. Diagnosis and evaluation of skeletal metastases require more frequently a combined approach of different diagnostic methods. Between the currently available imaging modalities, a major role is devoted to two radionuclide functional techniques namely scintigraphy and positron emission tomography (PET) imaging. Both these techniques require the use of different radiopharmaceuticals. The aim of this paper is to review the most important radiocompounds that can be successfully used to detect and/or characterize bone metastases.Current radiopharmaceuticals. 03/2013; -
Article: Peptide Imaging with Somatostatin Analogues: More than Cancer Probes.
[show abstract] [hide abstract]
ABSTRACT: Somastostatin (SS) scintigraphy (SRS) is an effective diagnostic tool for neuroendocrine tumours (NET). High diagnostic accuracy is based on the high affinity binding between SS and its receptors (sstr) expressed both in NET and in some non neoplastic cells. Different SS analogues have been proposed in clinical practice because of the short half-life of the native peptide. Among all synthetic compounds Pentetreotide labelled with In-111 is the most widely used for imaging because of high affinity for sstr 2 and 5. New tracers, showing a different and/or wider affinity, are now available and radio-labelling has been obtained both with gamma and positron emitters. The broader spectrum of interaction with sstr gives a better chance to detect, over NET, other pathological conditions, as chronic inflammation, because of the sstr expression on inflammatory cells, including activated lymphocytes, epithelioid and monocytes.Current radiopharmaceuticals. 03/2013; -

Article: Inflammatory bowel disease: value in diagnosis and management of MDCT-enteroclysis and 99mTc-HMPAO labeled leukocyte scintigraphy.
[show abstract] [hide abstract]
ABSTRACT: The aims of this study are: (a) to evaluate the reliability of Multidetector Computed Tomography Enteroclysis (MDCT-E) and (99m)Tc-HMPAO labeled leukocyte scintigraphy (TLLS), in inflammatory bowel disease, (b) to test the accuracy of the two techniques with regard to their histological results, (c) to define how each technique can influence the natural course of inflammatory bowel disease (IBD), (d) to assess the potential value of the two techniques combined. Thirty-seven patients with suspected IBD underwent MDCT-E and TLLS. We made a separate assessment of the results shown by the two methods and then compared and contrasted the histological results of the two. The latter, however, were either disappointing or not available in 15 patients who, for this reason, had to be dismissed from the study. As result, the number of participants eventually dropped to 22 subjects: 12 women, 10 men with an average age of 44 years. MDCT-E and TLLS were successful in all patients. Sensitivity, specificity, and efficiency values have been reported as follows: MDCT-E: 62%, 100%, 64%,100%, 11%, respectively. TLLS: 90%, 100%, 91%, 100%, 33%, respectively. The two methods combined: 95%, 100%, 95%, 100%, 50%, respectively. The two techniques can be employed in different stages of the natural course of the disease. In our experience, TLLS proved itself to be useful in the diagnosis of the disease and the assessment of its development. Conversely, MDCT-E proved itself to be more reliable in identifying the seat and the extent of the disease inside and outside the bowel wall as well as potential intra-peritoneal and extra-intestinal complications. The combined use of the two methods represents the Criterion Standard for diagnosing IBD with imaging.Abdominal Imaging 10/2010; 36(4):372-81. · 1.73 Impact Factor -

Chapter: Considerations About PET Isotopes
[show abstract] [hide abstract]
ABSTRACT: Human beings, like all living organisms, are made of bio-molecules. Health can be considered as the expression of homeostasis, i.e., the ability of a system to regulate its internal environment, thereby tending to maintain a stable and “normal” condition. In this sense, the real essence of life is the phenomenon in which multiple dynamic equilibrium and regulation mechanisms are needed to make homeostasis possible. Many diseases result from disturbances in homeostasis and are characterized by a condition known as homeostatic imbalance, where a molecular system goes out of equilibrium.05/2010: pages 7-11; -
Article: Nuclear medicine in multiple myeloma -- more than diagnosis.
[show abstract] [hide abstract]
ABSTRACT: Multiple myeloma (MM) is a neoplastic monoclonal proliferation of plasma cells, mainly involving bone marrow. To properly stage and manage patients with MM the clinician needs, at first, a complete skeletal survey, being more rarely present also extra skeletal locations. Today none of the available diagnostic imaging methods is able alone to answer to all the questions regarding staging, treatment, and follow up. Continuing to be alive the role of traditional radiology, implemented information can be added by CT and MRI. Concerning nuclear medicine, bone scintigraphy is affected by its low sensitivity. Tc-99m MIBI has been proposed in staging and in follow up, with most relevant clinical information deriving from the correlation of its whole body uptake's distribution with extent and activity of the disease. The prognostic value of MIBI has also been demonstrated. PET-FDG has been proposed in MM for its ability to detect whole-body metabolic active disease, giving relevant information in staging and prognosis. First studies have demonstrated that PET-FDG is more sensitive than other imaging modalities for localizing extra medullary sites of disease.Nuclear medicine review.

Article: Scintigraphic evaluation of oesophageal transit during radiotherapy to the mediastinum.
[show abstract] [hide abstract]
ABSTRACT: To quantitatively evaluate radiation-induced impaired oesophageal transit with oesophageal transit scintigraphy and to assess the relationships between acute oesophagitis symptoms and dysmotility. Between January 1996 and November 1998, 11 patients affected by non-small-cell carcinoma of the lung not directly involving the oesophagus, requiring adjuvant external beam radiotherapy (RT) to the mediastinum were enrolled. Oesophageal transit scans with liquid and semisolid bolus were performed at three pre-defined times: before (T0) and during radiation at 10 Gy (T1) and 30 Gy (T2). Two parameters were obtained for evaluation: 1) mean transit time (MTT); and 2) ratio between peak activity and residual activity at 40 seconds (ER-40s). Acute radiation toxicity was scored according to the joint EORTC-RTOG criteria. Mean values with standard deviation were calculated for all parameters. Analysis of variance (ANOVA) tests and paired t-Tests for all values were performed. An increase in the ER-40s from T0 to T1 or T2 was seen in 9 of 11 patients (82%). The mean ER-40s value for all patients increased from 0.8306 (T0) to 0.8612 (T1) and 0.8658 (T2). These differences were statistically significant (p < 0.05) in two paired t-Tests at T0 versus T2 time: overall mean ER-40s and upright ER-40s (p = 0.041 and p = 0.032, respectively). Seven patients (63%) showed a slight increase in the mean MTT value during irradiation but no statistically significant differences in MTT parameters were found between T0, T1 and T2 (p > 0.05). Using oesophageal scintigraphy we were able to detect early alterations of oesophageal transit during the third week of thoracic RT.BMC Gastroenterology 12/2008; 8:51. · 2.42 Impact Factor -

Article: Parotid function after selective deep lobe parotidectomy.
[show abstract] [hide abstract]
ABSTRACT: Selective deep lobe parotidectomy is a demanding technique, but it preserves healthy glandular tissue, improves cosmetic results and minimises the incidence of Frey's syndrome. We have evaluated postoperative function of the superficial lobe of the parotid after selective resection of the deep lobe. Fourteen patients who each had a mass involving the deep lobe of the parotid were selected from 127 patients with tumours of the parotid gland who were seen and treated between January 2001 and March 2004. Of the 14, 12 matched the study criteria. The preoperative diagnosis was made using both computed tomography (CT) and ultrasound or fine needle aspiration cytology, and the diagnosis was confirmed by histological analysis. All cases were treated by the same surgeon. At 6 months follow-up all patients had a House-Brackmann test, iodine starch test, and scintigraphy of both parotid glands. After scintigraphy the maximum uptake value and function of the gland were evaluated with the concentration index (CI) and the CI percentage ratio. The concentration function of the gland in the resected side of the study group had a mean (S.D.) CI index of 5.5 (3.6) and a CI percentage ratio of 84%. Selective deep lobe parotidectomy has the following advantages: it minimises the impact of treatment on the facial contour, it does not increase postoperative morbidity and it preserves the function of the gland.British Journal of Oral and Maxillofacial Surgery 04/2007; 45(2):108-11. · 1.95 Impact Factor -

Article: Continuous monitoring of left ventricle function by VEST in hemodialyzed patients.
[show abstract] [hide abstract]
ABSTRACT: Cardiovascular disease is a major cause of morbidity and mortality in chronic kidney disease. Radionuclide-based methods can be used for analyses on the perfusion of coronary arteries and ventricular function. The present study reports the use of a new procedure for continuous measurements of left ventricle function during a dialytic session with the use of a recently developed portable gamma radiation detector (ventricular function study system). On average, left ventricle ejection fraction and stroke volume progressively and continuously decreased throughout the session (end session versus baseline: -13.8% for ejection fraction, -25.9% for stroke volume, P<.02). A biphasic response was found for heart rate: a transient modest decrease (at session midpoint, -4.2%) followed by an increase up to values higher than baseline (end session, +4.7%). Cardiac output decreased by 10.4% at session midpoint (P=.023 versus baseline) without further reduction in the following hours. Mean changes in systolic pressure paralleled data for cardiac output. Individual changes in indices of left ventricle function were scattered and strongly were correlated with thickness of interventricular septum and telediastolic left ventricular volume measured by standard echocardiogram in the interdialytic period (R>.75, P<.05). Data indicate that the ventricular function study system could be a powerful tool for characterization of the profile of left ventricular function in hemodialyzed patients.Seminars in Nephrology 02/2006; 26(1):80-4. · 2.12 Impact Factor -
Article: Surgical treatment of differentiated thyroid carcinoma: a retrospective study.
[show abstract] [hide abstract]
ABSTRACT: A retrospective study was carried out to assessed reliability of the prognostic factors (histology, age, sex, and stage), and standard procedures for the surgical treatment of differentiated thyroid cancers (DTC). From the 144 DTC cases reviewed with follow-up ranging from 1 to 25 years (m = 6.33 years), total mortality for cancer was found to be 55% (8 patients), with a predictive positive value for recurrence of 95.4% and 91.8% at 12 and 24 months, respectively. Median survival was 8.8 years (range 1 to 25 years). The multivariate analysis showed that factors such as age > 45 years, histology of intermediate malignancy, size up to 1.5 cm, and presence of metastases, significantly worsened the prognosis, regardless of the intervention that was carried out. We suggest total thyroidectomy for the treatment of benign pathologies and confirmed or suspected cases of cancer. We reserve loboisthmectomy for the treatment of benign pathologies confined to one lobe or those with FNAB suggesting a follicular neoplasm.Frontiers in Bioscience 01/2006; 11:2206-12. · 3.52 Impact Factor -

ABSTRACT: We report a novel method for preparing samples for laser capture microdissection. The procedure described here permits extraction of intact RNA while preserving morphology, thus being suitable both for identification of specific cells and for analysis of their gene expression. The method is applicable to both mouse embryos and human tumors and may improve the preparation of cDNA libraries from specific cell types without interfering with histological diagnosis.Analytical Biochemistry 02/2002; 300(2):139-45. · 3.00 Impact Factor -
Article: Whole stomach transposition without gastric drainage procedure: a good surgical option to restore digestive continuity after esophagectomy.
[show abstract] [hide abstract]
ABSTRACT: After esophagectomy, the stomach is usually used to restore digestive continuity. To prevent postoperative delayed gastric emptying, most authors perform a gastric drainage procedure or transpose a tubulized stomach. The aim of our work is to evaluate the emptying of a transposed whole stomach without performing a pyloromyotomy or a pyloroplasty. From 1996 to January 2004, 45 patients underwent total esophagectomy for cancer or for caustic stenosis. Reconstruction of digestive continuity was realized through transposition of the whole stomach without performing a pyloric drainage procedure. At 12 months after the intervention, 35 patients (77.8%; 20 men and 15 women) were submitted to a gastric emptying scintigraphic study by means of ingestion of a mixed meal labeled with 37 MBq 99mTc-sulfur colloid. Mean half-emptying time was 71.4 minutes (range, 15-90 minutes; reference range, 83 +/- 34 minutes): all the patients were in the normal range except one. No patient complained of delayed gastric emptying symptoms. After esophagectomy, the transposition of the whole stomach without a pyloric drainage procedure seems to be an interesting option, and is not associated with delayed gastric emptying.International surgery 92(2):73-7. · 0.36 Impact Factor -
