Binostril versus mononostril approaches in endoscopic transsphenoidal pituitary surgery: clinical evaluation and cadaver study.

2016

OBJECTIVE Over the past 2 decades, endoscopy has become an integral part of the surgical repertoire for skull base procedures. The present clinical evaluation and cadaver study compare binostril and mononostril endoscopic transnasal approaches and the surgical techniques involved. METHODS Forty patients with pituitary adenomas were treated with either binostril or mononostril endoscopic surgery. Neurosurgical, endocrinological, ophthalmological, and neuroradiological examinations were performed. Ten cadaver specimens were prepared, and surgical aspects of the preparation and neuroradiological examination were documented. RESULTS In the clinical evaluation, 0° optics were optimal in the nas…

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…

Expression of the pea S -adenosylmethionine decarboxylase gene is involved in developmental and environmental responses

2002

A cDNA, able to complement the S-adenosyl-L-methionine decarboxylase (SAMdC; EC 4.1.1.50)-defective yeast strain Y342, has been isolated from pea (Pisum sativum L.). Expression of the SAMdC gene was characterised during pea development. Northern analysis showed a differential expression of the pea SAMdC gene in vegetative and reproductive tissues. The highest SAMdC mRNA levels were found in undifferentiated callus and tissues with high rates of cell division, and at the onset of fruit development. SAMdC expression was also induced in senescing ovaries, probably in relation to an accumulation of spermine during ovary senescence. Finally, the levels of SAMdC transcripts in leaves and shoots w…

Contribution of IL-17-producing {gamma}{delta} T cells to the efficacy of anticancer chemotherapy.

2011

IL-17 production by γδ T cells is required for tumor cell infiltration by IFN-γ–producing CD8+ T cells and inhibition of tumor growth in response to anthracyclines.

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…

P and R Wave Detection in Complete Congenital Atrioventricular Block

2009

Complete atrioventricular block (type III AVB) is characterized by an absence of P wave transmission to ventricles. This implies that QRS complexes are generated in an autonomous way and are not coordinated with P waves. This work introduces a new algorithm for the detection of P waves for this type of pathology using non-invasive electrocardiographic surface leads. The proposed algorithm is divided into three stages. In the first stage, the R waves located by a QRS detector are used to generate the RR series and time references for the other stages of the algorithm. In the second stage, the ventricular activity (QT segment) is removed by using an adaptive filter that obtains an averaged pa…

Syncope in pediatric patients: role of arrhythmias

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.…
