Surgical treatment of differentiated thyroid carcinoma: a retrospective study.

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.

Parotid function after selective deep lobe parotidectomy.

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.

Continuous monitoring of left ventricle function by VEST in hemodialyzed patients.

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.

A preservation method that allows recovery of intact RNA from tissues dissected by laser capture microdissection.

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.
