Non small-cell lung cancer with metastasis to thigh muscle and mandible: two case reports

INTRODUCTION: Lung cancer is the leading cause of cancer-related death in Europe and the US. Isolated metastases to skeletal muscle and the mandible are very uncommon. CASE PRESENTATION: This report presents two cases. Case 1 concerns a 45-year-old Caucasian woman affected by muscle metastasis of the right thigh from non-small-cell lung cancer. Case 2 concerns a 61-year-old Caucasian man affected by mandible metastasis from non-small-cell lung cancer. Both metastases were detected by diagnostic imaging studies. Both patients were treated with radiation therapy with palliative and antalgic intent. CONCLUSION: Radiation therapy was effective and well tolerated in both cases. Both our patients are alive, with follow-up of 18 months and five months, respectively

A novel RAB39B mutation and concurrent de novo NF1 mutation in a boy with neurofibromatosis type 1, intellectual disability, and autism: a case report

Background Mutations in RAB39B at Xq28 causes a rare form of X-linked intellectual disability (ID) and Parkinson’s disease. Neurofibromatosis type 1 (NF1) is caused by heterozygous mutations in NF1 occurring de novo in about 50% of cases, usually due to paternal gonadal mutations. This case report describes clinical and genetic findings in a boy with the occurrence of two distinct causative mutations in NF1 and RAB39B explaining the observed phenotype. Case presentation Here we report a 7-year-old boy with multiple café-au-lait macules (CALMs) and freckling, severe macrocephaly, peculiar facial gestalt, severe ID with absent speech, epilepsy, autistic traits, self-harming, and aggressiveness. Proband is an only child born to a father aged 47. Parents did not present signs of NF1, while a maternal uncle showed severe ID, epilepsy, and tremors.By RNA analysis of NF1, we identified a de novo splicing variant (NM_000267.3:c.6579+2T>C) in proband, which explained NF1 clinical features but not the severe ID, behavioral problems, and aggressiveness. Family history suggested an X-linked condition and massively parallel sequencing of X-exome identified a novel RAB39B mutation (NM_171998.2:c.436_447del) in proband, his mother, and affected maternal uncle, subsequently validated by Sanger sequencing in these and other family members. Conclusions The case presented here highlights how concurrent genetic defects should be considered in NF1 patients when NF1 mutations cannot reasonably explain all the observed clinical features

Preventing the acute skin side effects in patients treated with radiotherapy for breast cancer: the use of corneometry in order to evaluate the protective effect of moisturizing creams

BACKGROUND AND PURPOSE: The purpose of this study was to add, to the objective evaluation, an instrumental assessment of the skin damage induced by radiation therapy. MATERIALS AND METHODS: A group of 100 patients affected by breast cancer was recruited in the study over one year. Patients were divided into five groups of 20 patients. For each group it was prescribed a different topical treatment. The following products were used: Betaglucan, sodium hyaluronate (Neoviderm®), Vitis vinifera A. s-I-M.t-O.dij (Ixoderm®), Alga Atlantica plus Ethylbisiminomethylguaicolo and Manganese Cloruro (Radioskin1®) and Metal Esculetina plus Ginko Biloba and Aloe vera (Radioskin 2®); Natural triglycerides-fitosterols (Xderit®); Selectiose plus thermal water of Avene (Trixera+®). All hydrating creams were applied twice a day starting 15 days before and one month after treatment with radiations. Before and during treatment patients underwent weekly skin assessments and corneometry to evaluate the symptoms related to skin toxicity and state of hydration. Evaluation of acute cutaneous toxicity was defined according to the RTOG scale. RESULTS: All patients completed radiotherapy; 72% of patients presented a G1 cutaneous toxicity, 18% developed a G2 cutaneous toxicity, 10% developed a G3 toxicity, no one presented G4 toxicity. The corneometry study confirmed the protective role of effective creams used in radiation therapy of breast cancer and showed its usefulness to identify radiation-induced dermatitis in a very early stage. CONCLUSIONS: The preventive use of topic products reduces the incidence of skin side effects in patients treated with radiotherapy for breast cancer. An instrumental evaluation of skin hydration can help the radiation oncologist to use strategies that prevent the onset of toxicity of high degree. All moisturizing creams used in this study were equally valid in the treatment of skin damage induced by radiotherapy

Targeted gene panel screening is an effective tool to identify undiagnosed late onset Pompe disease

Mutations in the GAA gene may cause a late onset Pompe disease presenting with proximal weakness without the characteristic muscle pathology, and therefore a test for GAA activity is the first tier analysis in all undiagnosed patients with hyperCKemia and/or limb-girdle muscular weakness. By using MotorPlex, a targeted gene panel for next generation sequencing, we analyzed GAA and other muscle diseasegenes in a large cohort of undiagnosed patients with suspected inherited skeletal muscle disorders (n = 504). In this cohort, 275 patients presented with limb-girdle phenotype and/or an isolated hyperCKemia. Mutational analysis identified GAA mutations in ten patients. Further seven affected relatives were identified by segregation studies. All the patients carried the common GAA mutation c.-32-13T > G and a second, previously reported mutation. In the subcohort of 275 patients with proximal muscle weakness and/or hyperCKemia, we identified late-onset Pompe disease in 10 patients. The clinical overlap between Pompe disease and LGMDs or other skeletal muscle disorders suggests that GAA and the genes causing a metabolic myopathy should be analyzed in all the gene panels used for testing neuromuscular patients. However, enzymatic tests are essential for the interpretation and validation of genetic results. (C) 2018 Elsevier B.V. All rights reserved.Peer reviewe

The role of radiation therapy and systemic therapies in elderly with breast cancer

The focus of this review deals with the management of elderly patients with early stage breast cancer, discussing the role of systemic therapies [endocrine therapy (ET), chemotherapy, novel agents] and radiation therapy (RT). Several studies have evaluated in elderly low risk patients the possibility of omitting the RT but, at the same time, higher locoregional relapse (LR) rates without significant impact on overall survival (OS) were observed in all studies when RT was excluded. Technological improvements [intensity-modulated RT (IMRT), volumetric modulated arc therapy (VMAT), high dose brachy therapy (HDBT)] are very useful in order to reduce cosmetic outcome and improve quality of life of frail patients. The optimal sequence of ET, concomitant or sequential to RT, is currently under investigation, and specifically in the elderly it is questioned the possible choice of prolonged therapy after standard 5 years. Data regarding chemotherapy suggesting no benefit of OS in endocrine responsive diseases, whereas endocrine non-responsive breast cancer still showed a better outcome. Cyclophosphamide, methotrexate and 5-fluorouracil (CMF) regimen is recognized as the standard protocol, although age-dependent increase in therapy related mortality was reported. Neoadjuvant chemotherapy in elderly showed a lower ratio of pathological complete response in comparison to younger patients, but triple negative breast cancer patients showed a good prognosis regarding OS, comparable to younger patients. The risk of cardiotoxicity seems to increase with age, so the use trastuzumab in this setting is much debated. Currently, other anti-HER2 agents (pertuzumab, lapatinib) are used in neoadjuvant setting, but the data on elderly are still premature. Novel molecules are rapidly changing the clinical management of breast cancer patients but are tested especially in locally advanced and metastatic setting. Among these, particularly interesting are inhibitors of CDK4 and 6, alpelisib (PI3K enzymes mutations), immune checkpoint (PD1, PDL1, CTLA4) inhibitors, atezolizumab. Elderly patients are under-represented in clinical trials, although ageing can be frequently correlated with a decrease in the effectiveness of the immune system. For elderly women, treatment decisions should be individually decided, taking into account the geriatric assessment and limited life expectancy and tumor characteristics

Does Azathioprine induce endoscopic and histologic healing in pediatric inflammatory bowel disease? A prospective, observational study

Background: The new concept of disease remission for pediatric inflammatory bowel diseases (IBD) implies the achievement of mucosal healing. Aims: We aimed to evaluate endoscopic and histologic healing in children with Ulcerative Colitis (UC) and Crohn's disease (CD) in clinical remission after 52 weeks of Azathioprine. Methods: From December 2012 to July 2015 we prospectively enrolled IBD children starting Azathioprine. Enrolled patients in clinical remission underwent colonoscopy after 52 weeks. Macroscopic assessment was described with Mayo score and the simplified endoscopic score for UC and CD, respectively. For microscopic assessment, an average histology score was used. Data on inflammatory markers and fecal calprotectin were also collected. Results: Fourty-seven patients were included in the analysis. Endoscopic healing was detected in 20/26 (76.9%) UC children and 10/21 (47.6%) CD patients. Median Mayo score and simplified endoscopic score were significantly decreased at week 52 (p < 0.001; p = 0.005). Median average histology score was not significantly different at week 52 in both diseases. Fecal calprotectin was directly correlated with simplified endoscopic score (T0: r = 0.4, p = 0.05; T52: r = 0.5, p = 0.01), but not with Mayo score. No correlation was found between endoscopic and histologic scores. Conclusions: IBD children under Azathioprine reach endoscopic healing, but not histological remission

Hypofractionated breast cancer radiotherapy. Helical tomotherapy in supine position or classic 3D-conformal radiotherapy in prone position: which is better?

We propose a comparative dosimetric study of whole-breast hypofractionated radiation therapy using helical tomotherapy (HT) in supine position and 3-D conformal radiotherapy (3D-CRT) in prone position. Twelve patients undergoing breast-conserving therapy were retrospectively selected from October to December 2012. Specific dose-volume parameters were selected for the study. The target coverage was adequate in all patients for both techniques. Significant differences in lung dose distribution were observed: maximum dose (mean value over the 12 plans) was 23.41 Gy in HT plans and 6.65 Gy in 3D-CRT; V20 (i.e. the lung volume receiving 20 Gy) was 0.31% in HT plans and 0.0% in 3D-CRT plans. The mean dose to the heart was 5.57 Gy and 0.93 Gy, respectively. The differences between the two techniques were significant (p<0.05) only for some parameters. We noted better results in the prone position, but with HT, dose constraints were mentioned for the whole set of considered organs

Hepatitis from Greater celandine (Chelidonium majus L.): Review of literature and report of a new case

Ethnopharmacological relevance: Folk medicine is a rich source of useful therapeutic tools. Nevertheless, use of medicinal plants can have unwanted, negative effects. By means of the description of an adverse reaction to a herbal remedy, we highlight the need for better efficacy-toxicity studies on these products. Aim of the Study: To report a case of possible Chelidonium majus L. (Greater celandine)-induced hepatitis and evaluate the past published cases. Materials and methods: We outlined the main features of hepatitis associated with use of Chelidonium majus by providing a review of cases reported and analysing in detail a new one. Results: Several cases of acute hepatitis related to Greater celandine consumption were found in the literature. The assessment for causality using Naranjo probability scale showed a probable relationship between the liver injury and the consumption of Chelidonium majus in the case we described. Conclusions: Our case, along with the other ones reported in the literature, increases the concern about the safety of oral use of Chelidonium majus. Plants used in traditional medicine are not necessarily harmless. Customers and prescribers should be aware of this, especially when a herbal drug is used with therapeutic purposes in absence of reliable studies of clinical efficacy and benefit-risk assessment.
