[Regulatory evolution of the crime of infanticide].

The objective of the present study consists of the juridic-anthropological analysis of the infanticide, a phenomenon that nowadays is highly existent within the context of crime-settings. Particular consideration has been given to the legal developments of the infanticide act, which occurred simultaneously with the mutation of the socio-cultural contexts. Because the legislative process of the infanticide act has not evolved since 1981, it was possible to underline the criticisms and the inadequacy of such norm.

Breast scintigraphy with breast-specific γ-camera in the detection of ductal carcinoma in situ: a correlation with mammography and histologic subtype.

Unlabelled: Ductal carcinoma in situ (DCIS) is a subtype of breast cancer encountered increasingly in clinical practice because of the widespread use of screening mammography. In the present study, we evaluated the usefulness of breast-specific γ-camera (BSGC) scintigraphy in DCIS identification, describing the scintigraphic findings and their correlation with mammography and histologic subtype.

Methods: Thirty-three women, aged 41-81 y, with surgically proven DCIS were retrospectively reviewed.

The clinical impact of breast scintigraphy acquired with a breast specific γ-camera (BSGC) in the diagnosis of breast cancer: incremental value versus mammography.

We investigated the clinical impact of breast scintigraphy acquired with a breast specific γ-camera (BSGC) in the diagnosis of breast cancer (BC) and assessed its incremental value over mammography (Mx). A consecutive series of 467 patients underwent BSGC scintigraphy for different indications: suspicious lesions on physical examination and/or on US/MRI negative at Mx (BI-RADS 1 or 3), characterization of lesions suspicious at Mx (BI-RADS 4), preoperative staging in lesions highly suggestive of malignancy at Mx (BI-RADS 5). Definitive histopathological findings were obtained in all cases after scintigraphy: 420/467 patients had BC, while 47/467 patients had benign lesions.

The usefulness of Tc-99m-tetrofosmin SPECT/CT in the detection of residual tumors and axillary lymph node metastases in breast cancer patients following neoadjuvant therapy.

Single photon emission computed tomography (SPECT)/CT is emerging as a useful diagnostic tool in several oncological fields. In this prospective study, we assessed the usefulness of Tc-99m-tetrofosmin SPECT/CT in the detection of both residual breast tumors and axillary lymph node metastases following neoadjuvant therapy. Thirty-seven consecutive breast cancer patients scheduled to surgery following neoadjuvant therapy preoperatively underwent a Tc-99m-tetrofosmin SPECT/CT study, using a dual head gamma camera integrated with a x-ray tube for low-dose CT, including both breasts and axillary regions in the field of view.

131I SPECT/CT in the follow-up of differentiated thyroid carcinoma: incremental value versus planar imaging.

Unlabelled: Planar 131I scintigraphy is routinely used to detect radioiodine-avid metastases of differentiated thyroid carcinoma (DTC). However, the modality has limitations, such as low sensitivity and lack of anatomic landmarks. We investigated whether SPECT with integrated low-dose CT may have additional value over planar imaging in detecting residue and metastases in DTC patients.

The role of planar scintimammography with high-resolution dedicated breast camera in the diagnosis of primary breast cancer.

Planar scintimammography (SM) acquired with a conventional gamma camera has proved a useful complementary tool to mammography (Mx) in breast cancer (BC) diagnosis, but with unsatisfactory sensitivity in small size carcinomas. In this study we assessed the role of planar SM with a high-resolution dedicated breast camera (DBC) in BC diagnosis, comparing the results with those of Mx.A consecutive series of 145 patients scheduled for biopsy for suspected BC underwent Tc-99m tetrofosmin planar SM using a newly developed DBC.

Planar scintimammography and SPECT in neoadjuvant chemo or hormonotherapy response evaluation in locally advanced primary breast cancer.

Conventional imaging procedures have proved of limited value in assessing tumor response to neoadjuvant chemotherapy in locally advanced primary breast cancer (LAPBC). We evaluated the usefulness of radioisotopic procedures comparing planar scintimammography (SM) to SPECT, monitoring pre-surgery neoadjuvant chemo- or hormonotherapy response in 32 LAPBC patients. In all cases, 99mTc-tetrofosmin conventional planar SM and SPECT were acquired by dual-head gamma camera with HR parallel hole collimators.

Breast cancer axillary lymph node metastasis detection by a high-resolution dedicated breast camera: a comparative study with SPECT and pinhole SPECT.

We evaluated the usefulness of (99m)Tc-tetrofosmin planar scintigraphy acquired with a high-resolution (HR) dedicated breast camera in comparison with conventional single-photon emission computed tomography (SPECT) and pinhole-SPECT (P-SPECT) in breast cancer (BC) axillary lymph node metastasis detection in a consecutive series of 76 BC patients, 28 of whom had axillary lymph node metastases, including 9 positive at clinical examination. HR planar scintigraphy was true positive in only 7 patients with >3 palpable metastases (sensitivity: 25%), while SPECT was true positive in 23 of 28 cases (sensitivity: 82.1%) and P-SPECT in 25 of 28 (sensitivity: 89.

Scintimammography with dedicated breast camera in unifocal and multifocal/multicentric primary breast cancer detection: a comparative study with SPECT.

The aim of this study was to assess the usefulness of planar scintimammography (SM) with a high-resolution dedicated breast camera (DBC) compared to SPECT in unifocal and multifocal/multicentric primary breast cancer (BC) detection. DBC planar SM and conventional SPECT were acquired using 99mTc-tetrofosmin as radiotracer in 85 consecutive patients suspect for BC at conventional imaging and clinical examination. Scintigraphic data were related to histology in all cases.

99mTc-tetrofosmin SPECT in solitary pulmonary nodule evaluation.

A correct differential diagnosis between benign and malignant lesions is mandatory in patients with solitary pulmonary nodule (SPN). The aim of the present study was to investigate whether 99mTc-tetrofosmin SPECT may play a role in SPN evaluation.

Thyroid function in human immunodeficiency virus patients treated with highly active antiretroviral therapy (HAART): a longitudinal study.

Objective: Given that few and controversial data have been reported on thyroid function in human immunodeficiency virus (HIV) patients on highly active antiretroviral therapy (HAART), we further investigated whether HAART affects thyroid hormones.

Design And Patients: Two hundred two consecutive adult HIV patients in stable clinical condition were enrolled, 182 on HAART and 20 naïve; 128 were rechecked during follow-up. Body mass index (BMI), CD4 cell count, HIV RNA, hepatitis C and B virus status and infection duration were determined in all HIV patients and HAART duration in treated patients.

The usefulness of 99mTc-tetrofosmin SPECT in the detection of lung metastases from extrapulmonary primary tumors.

Purpose: The appearance of pulmonary metastases in neoplastic patients previously submitted to radical operation of an extrapulmonary primary tumor and with no recurrences and/or secondary distant localizations can markedly worsen disease prognosis if the lesions are in advanced stages and no longer removable by surgical procedures. In this study, we evaluated the usefulness of 99mTc-tetrofosmin scintigraphy, both planar and SPECT, in the detection of pulmonary metastases from previously treated extrapulmonary primary tumors, comparing the results with those obtained with CT.

Materials And Methods: We studied 73 patients, 33 M and 40 F, aged 24 to 79 yrs, had who undergone previously surgical resection extrapulmonary primary tumors; 31 patients had mammary, 13 gastrointestinal, 13 genitourinary, 13 thyroid and 3 laryngeal carcinomas.

The usefulness of neck pinhole SPECT as a complementary tool to planar scintigraphy in primary and secondary hyperparathyroidism.

Unlabelled: Pinhole SPECT (P-SPECT) has proven to be a high-resolution and sensitive method in both experimental and clinical studies. In this study, we investigated whether P-SPECT combined with conventional planar scintigraphy can give additional information in hyperfunctioning parathyroid gland detection in both primary hyperparathyroidism (pHPT) and secondary hyperparathyroidism (sHPT) since planar imaging has proved partially limited, especially in sHPT.

Methods: We studied 110 consecutive patients with HPT, selecting 67 patients who underwent neck surgery and had definitive histology: 48 with pHPT and 19 with sHPT.

The usefulness of single photon emission computerized tomography with pinhole collimator (P-SPECT) in preoperative localization of hyperfunctioning parathyroid glands in patients with secondary hyperparathyroidism.

Purpose: In this study the usefulness of parathyroid scintigraphy was evaluated in a group of patients affected by secondary hyperparathyroidism, combining the conventional double-tracer subtraction planar scintigraphy with pinhole-SPECT (P-SPECT) acquisition and comparing the scintigraphic data with those obtained by ultrasonography.

Materials And Methods: Twenty-four patients with secondary hyperparathyroidism were enrolled, 19 with chronic renal failure on haemodialysis and 5 with renal transplant. All patients underwent parathyroidectomy because of their unresponsiveness to medical therapy and/or severe osteodystrophy.

The usefulness of 99mTc-tetrofosmin SPECT in monitoring the response to chemotherapy in lung cancer patients.

We evaluated the usefulness of 99mTc-tetrofosmin (TF) scintigraphy in monitoring chemotherapy response in 31 inoperable lung cancer (LC) patients, 24 NSCLC and 7 SCLC. In all cases after 740 MBq 99mTc-TF i.v.

The usefulness of 99mTc-tetrofosmin SPECT in the detection of intrathoracic malignant lesions.

To evaluate the usefulness of 99mTc-tetrofosmin (TF) SPECT in the detection of intrathoracic malignant lesions, we studied 304 patients, 261 with malignant and 43 with benign lesions; 196 of the former had non-treated primary tumors, 193 lung cancer (LC) and 3 mesotheliomas, 11 had LC recurrences and 54 had metastases from different kinds of tumors. Twenty-nine patients with primary tumors were re-checked after chemotherapy or surgery. In all patients, after 740 MBq TF injection, both planar and SPECT images were acquired and analysed qualitatively, SPECT images also semiquantitatively.
