Circulating Antineutrophil Cytoplasmic Autoantibodies (anca) In 2 Cases of Tolosa-hunt Syndrome
No full textDifferent management of adrenocortical carcinoma in children compared to adults: is it time to share guidelines?
No full textPediatric and adult adrenocortical carcinomas differ in many respects but treatment is often similar in both age groups. The Journal of Clinical Oncology recently published the results of a risk-stratified single-arm interventional trial conducted by the Children’s Oncology Group in which 77 patients were treated in three different interventional cohorts. In this Point of View paper we comment on the treatment strategies adopted within the ARAR0332 trial in terms of surgery approach, duration of adjuvant therapies, and palliative chemotherapy. We focus on the differences in the treatment of pediatric ACC patients compared to the ESE/ENSAT and ESMO guidelines released in 2018 for adult patients. For example, patients in stratum 3 and 4 received 8 (instead of 6) cycles of EDP chemotherapy but 8 months (instead of 24) of mitotane adjuvant therapy. Bearing clearly in the mind that pediatric and adult ACC patients represent different settings, we wonder whether there could be some areas of intervention overlapping to constitute a continuum of disease across ages. Thus, pediatric and adult cohoperative groups should be encouraged to collaborate in order to reach common guidelines for the treatment of such a rare disease
Is Tolosa-hunt Syndrome A Limited Form of Wegeners Granulomatosis? : Report of 2 Cases With Antineutrophil Cytoplasmic Antibodies
No full textA new phosphorylcholine-coated polymethylpentene oxygenator for extracorporeal membrane oxygenation: a preliminary experience
No full textPhosphorylcholine coating has a major role in the improvement of biocompatibility, durability and antihrombogenicity of the circuit for extracorporeal membrane oxygenation (ECMO). Moreover, if heparin-induced thrombocytopenia ensues, removal of all the sources of heparin is challenging if the circuit is coated with heparin.We report our preliminary experience with the new EUROSETS A.L.ONE ECMO oxygenator (Eurosets, Medolla, MO, Italy), which is aimed at providing better biocompatibility thanks to its full coating with phosphorylcholine. We retrospectively collected data on the 16 patients supported with ECMO and with the EUROSETS A.L.ONE ECMO oxygenator at San Raffaele Hospital. Mean ECMO duration was 6 ± 4 days, and 37.5% of the patients died on ECMO. Four episodes of major bleeding and three episodes of minor bleeding were recorded. The oxygenator had an excellent performance in gas exchange and the median pressure drop was 57 (26-85) mmHg at full blood flow (2.5 L/m(2)/min).The EUROSETS A.L.ONE ECMO oxygenator was an excellent device in our preliminary experience. Further evaluation on a larger sample is encourage
High calprotectin level and intestinal polyps: What is the relationship?
No full textIn clinical paediatric practice faecal calprotectin, a protein derived from white blood cells, is a reliable, non-invasive and easy-to-perform marker, with a high positive predictive power to identify intestinal inflammation. It is very useful for the follow-up of IBD and its main indications are the differential diagnosis between functional bowel disorders and inflammatory diseases. Intestinal bleeding lesions (determining chronic occult bleeding and/or intermittent bleeding) may be due to a high calprotectin level in asymptomatic patients, and among them the intestinal polyps are the most frequent cause. The article reports the case of an 8-year-old male with occasional increase in faecal calprotectin and the feedback to the colonoscopy of a pedunculated single polyp

No full textLong term clinical and neurophysiological effects of cerebellar transcranial direct current stimulation in patients with neurodegenerative ataxia
No full textNeurodegenerative cerebellar ataxias represent a group of disabling disorders for which we currently lack effective therapies. Cerebellar transcranial direct current stimulation (tDCS) is a non-invasive technique, which has been demonstrated to modulate cerebellar excitability and improve symptoms in patients with cerebellar ataxias
Structural Brain Signature of FTLD Driven by Granulin Mutation.
No full textSeveral causative gene mutations have been identified in frontotemporal lobar degeneration (FTLD), including mutations within Granulin (GRN) genes. It was recently shown that FTLD patients carriers of GRN Thr272fs mutation [FTLD-GRN(m+)] exhibit more severe abnormalities, as assessed by magnetic resonance imaging (MRI), than those with sporadic FTLD [FTLD-GRN(m-)]. The aim of this study was to investigate the relationship between grey (GM) and white matter (WM) microstructural damage in FTLD patients, carriers, and non-carriers of the mutation. Twenty-three FTLD patients [6 GRN(m+) and 17 GRN(m-)] and 12 healthy subjects received an MRI scan including volumetric and diffusion imaging. GM was assessed using voxel-based morphometry, while the corpus callosum was reconstructed using diffusion tractography. Mean diffusivity and fractional anisotropy of the corpus callosum were compared between groups. FTLD patients showed widespread GM atrophy and altered diffusion indices in the corpus callosum when compared to healthy subjects. When contrasting GRN(m+) against GRN(m-) patients, the former group had more atrophy in the left frontal GM, and reduced fractional anisotropy and increased mean diffusivity in the left anterior part of the corpus callosum. Significant correlations between the GM and WM damage were found in GRN(m+) patients. This pattern of damage was able to predict some of the additional neuropsychological deficits observed in GRN(m+) as compared to GRN(m-) patients. A more prominent involvement of WM in GRN(m+) patients is consistent with the knowledge that GRN genes are expressed in the microglia. This involvement might be responsible for the accrual of additional GM atrophy via disconnection mechanisms

Ovarian Strumal Carcinoid: Case Report, Systematic Literature Review and Pooled Analysis
No full textBackground: Ovarian strumal carcinoid is a rare tumor in which thyroid (struma) and carcinoid components coexist. The disease is generally considered to be a borderline malignancy, however, cases with metastatic disease have been described. No data in the literature are available to guide diagnosis and therapy. Methods: We performed a pooled analysis and a systematic review of histopathological-confirmed strumal carcinoid cases published in the literature using the following keywords: “strumal carcinoid of the ovary”, “strumal carcinoid case report”. A case of strumal carcinoid tumor diagnosed and followed-up at the Medical Oncology Unit of Spedali Civili (Brescia, Italy) was also described and included. Results: Sixty-six eligible publications were identified, providing data from one hundred and seventeen patients, plus a case diagnosed at our institution. At presentation, among the eighty-eight patients with symptomatic disease, 37% of patients suffered from abdominal distention and 49% from pain due to a growing abdominal tumor mass, 37% from constipation (peptide YY was analyzed in only nine of them, resulting above the physiologic range). Surgery was the primary therapy in 99% of the patients. Three patients had metastatic disease at diagnosis and five patients underwent recurrence after radical surgery. Histology at disease recurrence concerned the thyroid component in two patients, the carcinoid component in two patients, both histologies in one patient. Median disease-free survival and overall survival in this series were not attained. Conclusion: Strumal carcinoid of the ovary generally presents a benign behavior and surgery is curative in most cases. However, a small group of patients with this disease can undergo disease recurrence due to both the thyroid and the neuroendocrine (carcinoid) components. A follow-up in radically operated patients is therefore needed, particularly in those with a voluminous disease at diagnosis
