Purpose: Thoracic ultrasound (TUS) has been proposed as an easy-option replacement for chest X-ray (CXR) in emergency diagnosis of pneumonia, pleural effusion, and pneumothorax. We investigated CXR unforeseen diagnosis, subsequently investigated by TUS, considering its usefulness in clinical risk assessment and management and also assessing the sustainability of telementoring. Patients and methods: This observational report includes a period of 6 months with proactive concurrent adjunctive TUS diagnosis telementoring, which was done using freely available smartphone applications for transfer of images and movies. Results: Three hundred and seventy emergency TUS scans (excluding trauma patients) were performed and telementored. In 310 cases, no significant chest pathology was detected either by CXR, TUS, or the subsequent work-up; in 24 patients, there was full concordance between TUS and CXR (ten isolated pleural effusion; eleven pleural effusion with lung consolidations; and three lung consolidation without pleural effusion); in ten patients with lung consolidations, abnormalities identified by CXR were not detected by TUS. In 26 patients, only TUS diagnosis criteria of disease were present: in 19 patients, CXR was not diagnostic, ie, substantially negative, but TUS detected these conditions correctly, and these were later confirmed by computed tomography (CT). In seven patients, even if chest disease was identified by CXR, such diagnoses were significantly modified by ultrasound, and CT confirmed that TUS was more appropriate. The overall respective individual performances of CXR and TUS for the diagnosis of a pleuralpulmonary disease in emergency are good, with accuracy >95%. Conclusion: About 20% of pneumonia cases were detectable only by CXR and 20% only by TUS and not by CXR; ie, about 40% of patients may have been misdiagnosed if, by chance, only one of the two tools had been used. The concurrent use of TUS and CXR increases the overall sensitivity and specificity. The contribution of expert telementoring and final reappraisal is a valuable and sustainable element for emergency physicians’ training and performance, contributing reasonably to mitigation of clinical risks. © 2017 Interrigi et al.

Objective: This study aimed to evaluate the surgical treatment of acute pancreatitis in Italy and to assess compliance with international guidelines. Methods: A series of 1173 patients in 56 hospitals were prospectively enrolled and their data analysed. Results: Twenty-nine patients with severe pancreatitis underwent surgical intervention. Necrosectomy was performed in 26 patients, associated with postoperative lavage in 70% of cases. A feeding jejunostomy was added in 37% of cases. Mortality was 21%. Of the patients with mild pancreatitis, 714 patients with a biliary aetiology were evaluated. Prophylactic treatment of relapses was carried out in 212 patients (36%) by cholecystectomy and in 161 using a laparoscopic approach. Preoperative endoscopic retrograde cholangiopancreatography was associated with cholecystectomy in 83 patients (39%). Forty-seven patients (22%) were treated at a second admission, with a median delay of 31 days from the onset of pancreatitis. Eighteen patients with severe pancreatitis underwent cholecystectomy 37.9 days after the first admission. There were no deaths. Discussion: The results indicate poor compliance with published guidelines. In severe pancreatitis, early surgical intervention is frequently performed and enteral feeding is seldom used. Only a small number of patients with mild biliary pancreatitis undergo definitive treatment (i.e. cholecystectomy) within 4 weeks of the onset of pancreatitis. © 2010 International Hepato-Pancreato-Biliary Association.

Purpose Carboplatin/paclitaxel is the standard first-line chemotherapy for patients with advanced ovarian cancer. Multicentre Italian Trials in Ovarian Cancer-2 (MITO-2), an academic multicenter phase III trial, tested whether carboplatin/pegylated liposomal doxorubicin (PLD) was more effective than standard chemotherapy. Patients and Methods Chemotherapy-naive patients with stage IC to IV ovarian cancer (age ≤ 75 years; Eastern Cooperative Oncology Group performance status ≤ 2) were randomly assigned to carboplatin area under the curve (AUC) 5 plus paclitaxel 175 mg/m2 or to carboplatin AUC 5 plus PLD 30 mg/m2, every 3 weeks for six cycles. Primary end point was progression-free survival (PFS). With 632 events in 820 enrolled patients, the study would have 80% power to detect a 0.80 hazard ratio (HR) of PFS. Results Eight hundred twenty patients were randomly assigned. Disease stages III and IV were prevalent. Occurrence of PFS events substantially slowed before obtaining the planned number. Therefore, in concert with the Independent Data Monitoring Committee, final analysis was performed with 556 events, after a median follow-up of 40 months. Median PFS times were 19.0 and 16.8 months with carboplatin/PLD and carboplatin/paclitaxel, respectively (HR, 0.95; 95% CI, 0.81 to 1.13; P = .58). Median overall survival times were 61.6 and 53.2 months with carboplatin/PLD and carboplatin/paclitaxel, respectively (HR, 0.89; 95% CI, 0.72 to 1.12; P = .32). Carboplatin/PLD produced a similar response rate but different toxicity (less neurotoxicity and alopecia but more hematologic adverse effects). There was no relevant difference in global quality of life after three and six cycles. Conclusion Carboplatin/PLD was not superior to carboplatin/paclitaxel, which remains the standard first-line chemotherapy for advanced ovarian cancer. However, given the observed CIs and the different toxicity, carboplatin/PLD could be considered an alternative to standard therapy. © 2011 by American Society of Clinical Oncology.

No biomarker is available to predict prognosis of patients with advanced ovarian cancer (AOC) and guide the choice of chemotherapy. We performed a prospective-retrospective biomarker study within the MITO2 trial on the treatment of AOC.MITO2 is a randomised multicentre phase 3 trial conducted with 820 AOC patients assigned carboplatin/paclitaxel (carboplatin: AUC5, paclitaxel: 175 mg/m, every 3 weeks for 6 cycles) or carboplatin/PLD-pegylated liposomal doxorubicin (carboplatin: AUC5, PLD: 30 mg/m, every 3 weeks for 6 cycles) as first line treatment. Sixteen biomarkers (pathways of adhesion/invasion, apoptosis, transcription regulation, metabolism, and DNA repair) were studied in 229 patients, in a tissue microarray. Progression-free and overall survival were analysed with multivariable Cox model.After 72 months median follow-up, 594 progressions and 426 deaths were reported; there was no significant difference between the two arms in the whole trial. No biomarker had significant prognostic value. Statistically significant interactions with treatment were found for DNA-dependent protein kinase (DNA-PK) and phosphorylated acetyl-coenzymeA carboxylase (pACC), both predicting worse outcome for patients receiving carboplatin/paclitaxel.These data show that in presence of DNA-PK or pACC overexpression, carboplatin/paclitaxel might be less effective than carboplatin/PLD as first line treatment of ovarian cancer patients. Further validation of these findings is warranted.

Antiphospholipid syndrome is an autoimmune disorder characterized by recurrent venous or arterial thrombosis and/or pregnancy-related problems associated with persistently elevated levels of antiphospholipid antibodies. The kidney is a major target organ in both primary and secondary antiphospholipid syndrome. This review describes several aspects of the renal involvement in the primary form of the syndrome, in particular the histological pattern of the so-called antiphospholipid syndrome nephropathy (APSN). APSN is a vascular nephropathy characterized by small vessel vaso-occlusive lesions associated with fibrous intimal hyperplasia of interlobular arteries, recanalizing thrombi in arteries and arterioles, and focal atrophy, a constellation of morphological lesions suggestive of primary antiphospholipid syndrome. © 2016, Italian Society of Nephrology.

Ovarian clear cell carcinoma (OCCC) is a subtype of epithelial ovarian cancer with characteristic biological features and aggressive clinical behavior. OCCCs show a pattern of gene mutations different from other type I ovarian malignancies, notably a higher frequency of PIK3CA mutations. In low grade serous ovarian cancer, KRAS and BRAF mutations are frequent, but little data are available on the mutational status of these genes in OCCCs. To clarify this issue, we designed a clinicopathological study with the aim to establish the incidence of KRAS, NRAS, and BRAF hot spot mutations in OCCC. Between December 2006 and June 2012, 22 patients with a proven diagnosis of OCCC were admitted to our Institutions. In all cases, final diagnosis was established according to FIGO and WHO criteria. All women received complete surgical staging. The PyroMark Q24 system (Qiagen GmbH, Hilden, Germany) was used for pyrosequencing analysis of KRAS, NRAS, and BRAF hot spot regions on 2.5-μm sections of formalin-fixed paraffin-embedded tissue from primary OCCC. Pyrosequencing analysis of KRAS, NRAS, and BRAF hot spot regions revealed the presence of mutations only at codon 12 in exon 2 of KRAS in 3 of 22 (14 %) cases. We found no mutations in the hot spot regions of NRAF (exons 2, 3, 4) or BRAF (exon 15). The median age of women with a KRAS mutated OCCC was 74 years. These OCCC were unilateral FIGO stage IA lesions in two cases associated with foci of endometriosis. We conclude that in 14 % of OCCCs, a KRAS mutation occurs in codon 2 exon 2. NRAS and BRAF mutations were not found. © 2014 Springer-Verlag.

Background: Based on the high chemosensitivity of germ-cell tumors (GCTs), the concept of high-dose chemotherapy (HDCT) has been developed worldwide and investigated through many clinical trials. It has been carried out in different clinical settings, ranging from resistant or absolute refractory disease to chemosensitive relapse. HDCT with stem-cell support has been also explored as a part of first-line strategy for poor-prognosis patients. Patients and methods: Our review summarized results from clinical trials evaluating the role of HDCT in patients with advanced GCTs. So far available data were obtained through a Medline search of English-language literature. Results: Several phase II trials and retrospective series have shown a possible benefit for GCT patients with recurrent disease as well as in first-line setting. Despite these results, data derived from randomized phase III studies failed to demonstrate any survival advantage for HDCT over conventional chemotherapy. Conclusions: The role of HDCT in GCTs remains controversial. We need new prospective studies based on prognostic factors with multiple transplants of carboplatin and etoposide as the preferred high dose regimen. At present, based mainly on retrospective and phase II studies, HDCT may represent a therapeutic option for patients with primary refractory disease or for those with a second or further relapse. © The Author 2011.

Numerous studies have established that High Mobility Group A (HMGA) proteins play a pivotal role on the onset of human pituitary tumors. They are overexpressed in pituitary tumors, and, consistently, transgenic mice overexpressing either the Hmga1 or the Hmga2 gene develop pituitary tumors. In contrast with HMGA2, HMGA1 overexpression is not related to any rearrangement or amplification of the HMGA1 locus in these tumors. We have recently identified 2 HMGA1 pseudogenes, HMGA1P6 and HMGA1P7, acting as competitive endogenous RNA decoys for HMGA1 and other cancer related genes. Here, we show that HMGA1 pseudogene expression significantly correlates with HMGA1 mRNA levels in growth hormone and nonfunctioning pituitary adenomas likely inhibiting the repression of HMGA1 through microRNAs action. According to our functional studies, these HMGA1 pseudogenes enhance the proliferation and migration of the mouse pituitary tumor cell line, at least in part, through their upregulation. Our results point out that the overexpression of HMGA1P6 and HMGA1P7 could contribute to increase HMGA1 levels in human pituitary tumors, and then to pituitary tumorigenesis. © 2015 Taylor & Francis Group, LLC.
