Randomised clinical trial: preventive treatment with topical rectal beclomethasone dipropionate reduces post-radiation risk of bleeding in patients irradiated for prostate cancer

BACKGROUND: Radiotherapy is an established treatment modality for prostate cancer; however, up to a third of patients develops a radiation-induced proctopathy. AIM: To assess the effect of topical beclomethasone dipropionate (BDP) in the prevention of radiation-induced proctopathy in patients undergoing radiotherapy for prostate cancer through a double-blind, placebo-controlled, randomised trial. METHODS: Patients were randomised either to BDP or to placebo (PL). Patients received daily a 3mg BDP enema or identical-looking PL during radiotherapy and, subsequently, two 3mg BDP suppositories or PL for 4 more weeks. Clinical and endoscopic evaluations before, 3 and 12months after the end of radiotherapy were assessed with the RTOG/EORTC toxicity scales, the modified Simple Clinical Colitis Activity Index (SCCAI), the modified Inflammatory Bowel disease Quality of Life Index (IBDQ) and the Vienna Rectoscopy Score (VRS). RESULTS: From June 2007 to October 2008, 120 patients were randomised to the BDP (n=60) and PL (n=60) arms and were followed up for 12months. The overall assessment of rectal side effects did not show significant differences between the two groups of treatment. However, when only rectal bleeding was considered, a significantly reduced risk was observed in patients on BDP (OR 0.38; 95% CI 0.17-0.86; P=0.02; NNT=5). Patients on BDP had also significantly lower VRS scores (P=0.028) and significantly higher IBDQ scores (P=0.034). CONCLUSIONS: Preventive treatment with topical rectal BDP during radiotherapy for prostate cancer significantly reduces the risk of rectal bleeding and radiation-induced mucosal changes and improves patient's quality of life, but does not influence other radiation-induced symptoms

SERUM THYROGLOBULIN CONCENTRATIONS AND (131)I WHOLE-BODY SCAN RESULTS IN PATIENTS WITH DIFFERENTIATED THYROID CARCINOMA AFTER ADMINISTRATION OF RECOMBINANT HUMAN THYROID-STIMULATING HORMONE

Our results show that the measurement of serum Tg concentrations after rhTSH has a higher diagnostic value than whole-body scanning in detecting the persistence of thyroid tissue. Therefore, rhTSH should be administered in TSH-suppressed patients with basal serum Tg concentrations of <2 ng/mL because the increment in serum Tg concentrations may reveal the persistence of thyroid tissue in these patients

Clinical and histological characteristics of papillary thyroid microcarcinoma: results of a retrospective study in 243 patients

CONTEXT: The recognition of thyroid microcarcinoma has increased due to the widespread use of ultrasound-guided fine-needle aspiration biopsies. OBJECTIVE: The objective of this study was to describe histological and clinical characteristics of papillary thyroid microcarcinoma (PTMC) less than or equal to 1 cm. DESIGN: This study was a retrospective cohort. SETTING: This study was conducted at a university hospital endocrine clinic. PATIENTS: Over a 9-yr period, 243 consecutive patients with PTMC were studied. RESULTS: PTMC was an incidental finding at surgery in 21.4% of the PTMC cases. There were no differences in the clinical characteristics between those with incidental PTMC and those with suspected thyroid carcinoma. None of the patients with a cancer less than 8 mm had distant metastases, whereas distant metastases were observed in patients with cancers >/= 8 mm (P </= 0.05). Disease-related mortality was not observed. CONCLUSIONS: PTMC is prevalent in the population. Among patients with PTMC, tumor size more than 8 mm is associated with more aggressive disease

Clinical value of different responses of serum thyroglobulin to recombinant human thyrotropin in the follow-up of patients with differentiated thyroid carcinoma

In the present study we examined the clinical value of a differential response of thyroglobulin (Tg) concentration after recombinant human thyrotropin (rhTSH) stimulation (rhTSH Tg testing) and its correlation with (131)I uptake and whole-body scanning (rhTSH-WBS) in 104 patients who had previously undergone near-total thyroidectomy and (131)I ablation for differentiated thyroid carcinoma (DTC). rhTSH Tg testing was considered negative for rhTSH-Tg less than 0.9 ng/mL, low positive for rhTSH-Tg of 1-5 ng/mL and high positive for rhTSHTg greater than 5 ng/mL. rhTSH Tg testing was negative in 70 patients, 1 of whom had a lymph-node metastasis, but no (131)I uptake. Seven patients had low positive rhTSH Tg testing and no (131)I uptake, but 2 of these patients had cervical lymph node metastases. Twenty-seven patients had high positive rhTSH Tg testing and (131)I uptake was detected in lung, bone, or mediastinum in 11. Imaging techniques (computed tomography [CT], magnetic resonance imaging [MRI], fluorine-18 2-fluoro-2-deoxy-D-glucose-positron emission tomography [FDGPET]) documented metastatic disease in 22. In conclusion, our results suggest that any rise in rhTSH-Tg, even at low level, should raise the suspicion of persistent or recurrent DTC. Patients with rhTSH-Tg at high level should be carefully evaluated, because DTC persistence is highly probable. TSH-WBS provides little adjunctive information

Impact of the Type of Dialysis on Time to Transplantation: Is It Just a Matter of Immunity?

Background: Renal transplantation represents the therapeutic gold standard in patients with end stage renal disease (ESRD). Still the role of pre-transplant dialysis in affecting time to transplantation has yet to be determined. We wanted to verify whether the type of renal replacement therapy (hemodialysis vs. peritoneal dialysis) affects time to transplantation and to identify clinical features related to the longer time to transplantation. Methods: We performed a retrospective single-center observational study on patients who had received a transplant in the Bologna Transplant Unit from 1991 to 2019, described through the analysis of digital transplant list documents for sex, age, body mass index (BMI), blood group, comorbidities, underlying disease, serology, type of dialysis, time to transplantation, Panel Reactive Antibodies (PRA) max, number of preformed anti Human Leukocyte Antigens (HLA) antibodies. A p-value &lt; 0.05 was considered statistically significant. Results: In the 1619 patients analyzed, we observed a significant difference in time to transplant, PRA max and Preformed Antibodies Number between patients who received Hemodialysis (HD) and Peritoneal dialysis (PD). Then we performed a multiple regression analysis with all the considered factors in order to identify features that support these differences. The clinical variables that independently and directly correlate with longer time to transplantation are PRA max (p &lt; 0.0001), Antibodies number (p &lt; 0.0001) and HD (p &lt; 0.0001); though AB blood group (p &lt; 0.0001), age (p &lt; 0.003) and PD (p &lt; 0.0001) inversely correlate with time to transplantation. Conclusions: In our work, PD population received renal transplants in a shorter period of time compared to HD and turned out to be less immunized. Considering immunization, the type of dialysis impacts both on PRA max and on anti HLA antibodies
