Quantification of the risk of relapses after thyroid loboisthmusectomy for benign thyroid nodules

2006

AIM OF THE STUDY: To evaluate correlations between pre-operating epidemiological, clinical and diagnostic data and relapses concerning to patients operated on for benign thyroid nodules. MATERIAL AND METHODS: The AA. carried out a new ultrasonographic exam in 155 patients selected at random among 1012 treated by thyroid lobectomy between September 1976 and December 2002; 107 relapses were found (69%). The obtained data are analysed by chi2 test and a significant correlation between recurrence and data preceding first operation was found: non-homogeneous thyroid structure, multiple nodules, presence of peri-lesional halo, anti-thyroid antibodies, and non-adenomatous histological structure. C…

Leukocyte migration test (LMT) in patients with thyroid disease: the response to human thyroid subcellular fractions.

1981

The response of circulating leukocytes to thyroid subcellular fractions was investigated in 19 patients with Graves' disease, 15 patients with Hashimoto's thyroiditis, 7 patients with toxic adenoma, 19 patients with nontoxic goiter and in 10 healthy students as control subjects. For this purpose, the leukocyte migration test of Soborg and Bendixen was performed against human crude thyroid extract (CTE), cell plasma membranes, nuclei, ribosomes, mitochondria and microsomes. Our results show positive LMT against: 1) CTE in patients with Graves' disease (61 +/- 13, p less than 0.001) and Hashimoto's thyroiditis (65 +/- 11, p less than 0.001) compared to controls (90 +/- 11); 2) cell plasma mem…

Toxic adenoma and papillary thyroid carcinoma in a patient with Graves' disease.

1999

A case of a very rare association of toxic adenoma and papillary carcinoma with Graves’ disease is presented. A 34-year-old woman developed Graves’ disease with mild ophthalmopathy. An ultrasound revealed diffuse thyroid enlargement with a hypoechoic pattern and a hypoechoic nodule with regular edges of 1.6 cm in diameter at the lower pole of the left lobe. A thyroid 131I scintiscan showed a diffuse and homogeneous 131I distribution. The 131I uptake (RAIU) was elevated. One year later, while still on a low dose of methimazole, the patient had a recurrence of hyperthyroidism following an iodine load from a contrast agent. A further thyroid ultrasound confirmed the previously described patter…

Response of membrane-bound ATPase of Micrococcus luteus to heat and ultraviolet light.

1976

It is shown that the properties of ATPase (EC 3.6.1.3) of Micrococcus luteus depend only to some extent on the state of the membrane to which it is attached. Its interaction with the membrane appears to be largely controlled by polar forces. It is shown, however, that the UV-sensitivity of the membrane-bound ATPase is also significantly influenced by the state of membrane lipids.

Cyclophosphamide plus Epidoxorubicin and 5-Fluorouracil with Folinic Acid as a Novel Treatment in Metastatic Breast Cancer: Preliminary Results of a …

1991

Twenty consecutive patients with advanced breast cancer were treated with a combination of cyclophosphamide 600 mg/m2 i.v. on day 1, epidoxorubicin 75 mg/m2 on day 1, and 5-fluorouracil 375 mg/m2 i.v. with folinic acid 200 mg/m2 i.v. on days 1----3. The overall response rate was 60%, with 10% of patients showing a complete response with a mean duration of 11.1 + months, and 50% of patients a partial response of 7.4 + months. A stabilization of 5.2 + months was obtained in 20% of cases, while 20% of patients progressed. The most frequently observed toxicity was leukopenia, while expected mucosal toxicities were rather mild.

Short-term therapy for recurrent abortion using intravenous immunoglobulins: Results of a double-blind placebo-controlled Italian study

1997

It is still unclear whether i.v. immunoglobulins (Ig) can facilitate the reproductive prognosis of women who have suffered recurrent pregnancy loss. We report the results of a multicentre placebo-controlled study on the effect of Ig administration on pregnancy outcome in 46 women who had suffered at least three recurrent miscarriages. All were screened to exclude chromosomal or Müllerian abnormalities, the presence of antinuclear antibodies, lupus anticoagulant (LA) or elevated titres of anticardiolipin antibodies which may have revealed an underlying autoimmune problem. To avoid a selection bias towards ongoing pregnancies, i.v. Ig or placebo were administered between weeks 5 and 7 of gest…

Exploring the reciprocal modulation of time and space in dancers and non-dancers.

2014

We explored whether time and space representations modulate each other in subjects that are trained to integrate time and space dimensions, i.e., professional dancers. A group of dancers, and one of non-dancers, underwent two different tasks employing identical stimuli. A first static central line could last one of three possible durations and could have one of three possible lengths. A second growing line appeared from the left or right of the screen and grew up toward the opposite direction at constant velocity. In the Spatial task, subjects encoded the length of the static line and stopped the growing line when it had reached half the length of the static one, regardless of time travel. …

A 1-year maintenance after early adjuvant intravesical chemotherapy has a limited efficacy in preventing recurrence of intermediate risk non-muscle-i…

2010

Abstract OBJECTIVE: To evaluate the efficacy of 1-year maintenance after a 6-week cycle of early intravesical chemotherapy, as the role of maintenance in intravesical chemotherapy is debated. PATIENTS AND METHODS: Between May 2002 and August 2003, 577 patients with non-muscle-invasive bladder cancer (NMI-BC) underwent transurethral resection (TUR) and early intravesical chemotherapy (epirubicin, 80 mg/50 mL). They were randomized between a 6-week induction cycle and the induction cycle plus maintenance with 10 monthly instillations. In all, 95 patients with T1G3, Tis or single and primary Ta-T1 G1-G2 tumours were excluded; 482 patients at intermediate risk of recurrence continued the study.…

The pancreatic beta-cell response to intravenous administration of glucose in elderly subjects.

1970

A study was made of the serum insulin level after the intravenous administration of glucose (0.33 gm/ kg) in two groups of normal subjects—18 in the 60–85 age bracket, and 16 in the 23–45 age bracket. All had a normal coefficient of glucose utilization and a normal blood glucose curve after intravenous administration of glucose. Serum insulin was assayed by the radio-immunological method, with use of an ion exchange resin. Blood samples were drawn at 2, 5, 10, 30, 45 and 60 minutes after the end of the glucose infusion. In the elderly subjects the maximal value was reached only after 5 minutes and the mean value was 39± 9 µU/ml (range, 27–50), whereas in the younger subjects the serum insul…
