Abstract:

Introduction: Skin toxicity is a frequent side effect of radio and chemo-treatments in patients treated for breast cancer after conservative surgery. The aim of this paper is to report our experience in the management of skin toxicity evaluating radiotherapy planning and using preventive local aids. Materials and Methods: We have observed 300 patients undergoing radiotherapy. All received the prescription of a prophylactic moisturizing cream. Skin toxicity was valuated according to Acute Radiation Morbidity Scoring Criteria of the RTOG. Moreover, in a subgroup of 100 patients, we correlated the study of breast volume and features of treatment plans, with the addition of topic prophylactic treatment, using an oral therapy based on Resveratrol, Lycopene, Vitamin C and Anthocyanins (Ixor?). In another subgroup, 100 patients were subjected to corneometry assessing numerically skin hydration before, during and after radiotherapy. Results: In all patients, we related skin toxicity and the type of cream used. All patients completed the radiotherapy treatment, and G4 cutaneous toxicity was not observed in any of them. In patients treated with topic treatment and therapy based on Resveratrol, Lycopene, Vitamin C and Anthocyanins (Ixor?), the protective effect of (Ixor?) is more detected in patients with PTV (Planning Target Volume) <500 ml, when Dmax reaches values lower or equal to 107%, but not exceeding 110% of the prescribed dose, and in patients undergoing adjuvant chemotherapy with anthracyclines and taxanes. The values of corneometry allow us to evaluate the moisturizing

Improving Service Management in the Internet of Things
Chiara Sammarco,Antonio Iera
Sensors , 2012, DOI: 10.3390/s120911888
Abstract: In the Internet of Things (IoT) research arena, many efforts are devoted to adapt the existing IP standards to emerging IoT nodes. This is the direction followed by three Internet Engineering Task Force (IETF) Working Groups, which paved the way for research on IP-based constrained networks. Through a simplification of the whole TCP/IP stack, resource constrained nodes become direct interlocutors of application level entities in every point of the network. In this paper we analyze some side effects of this solution, when in the presence of large amounts of data to transmit. In particular, we conduct a performance analysis of the Constrained Application Protocol (CoAP), a widely accepted web transfer protocol for the Internet of Things, and propose a service management enhancement that improves the exploitation of the network and node resources. This is specifically thought for constrained nodes in the abovementioned conditions and proves to be able to significantly improve the node energetic performance when in the presence of large resource representations (hence, large data transmissions).
The influence of landslide shape and continental shelf on landslide generated tsunamis along a plane beach
E. Renzi,P. Sammarco
Natural Hazards and Earth System Sciences (NHESS) & Discussions (NHESSD) , 2012,
Abstract: This work proposes an advancement in analytical modelling of landslide tsunamis propagating along a plane beach. It is divided into two parts. In the first one, the analytical two-horizontal-dimension model of Sammarco and Renzi (2008) for tsunamis generated by a Gaussian-shaped landslide on a plane beach is revised and extended to realistic landslide shapes. The influence of finiteness and shape of the slide on the propagating waves is investigated and discussed. In the second part, a new model of landslide tsunamis propagating along a semi-plane beach is devised to analyse the role of the continental platform in attenuating the wave amplitude along the shoreline. With these parameters taken into account, the fit with available experimental data is enhanced and the model completed.

Revista do Departamento de Geografia , 1994, DOI: 10.7154/rdg.v0i8.220
Abstract: A necessidade de se dispor de mapeamentos básicos em escalas grandes sempre atualizados leva à implanta o de uma sistemática de atualiza o contínua por parte dos órg os responsáveis pela manuten o das bases cartográficas ao nível regional ou municipal. S o analisadas algumas alternativas metodológicas de atualiza o, propondo-se o aproveitamento de todas as informa es disponíveis nos órg os da administra o pública, e mesmo em entidades particulares, através do estabelecimento de fluxo de informa es entre produtores e usuários de cartografia para alimenta o do sistema. Ressalta o papel da integra o entre vários setores das prefeituras e as concessionárias de servi os públicos para assegurar a convergência de informa es, sem a qual se inviabiliza o processo de atualiza o contínua a baixo custo. O sucesso do trabalho de atualiza o depende da opera o de um sistema cartográfico municipal ou regional, intimamente ligado às atividades de gest o territorial.

A C1-inhibitor rare mutation: Early diagnosis of hereditary angioedema in a paediatric patient  [PDF]
Maria Cristina Maggio, Piero Sammarco, Carmelo Fabiano, Giovanni Corsello
Open Journal of Pediatrics (OJPed) , 2013, DOI: 10.4236/ojped.2013.31008
Abstract:

Hereditary angioedema secondary to C1-inhibitor deficiency is a rare autosomal dominant disorder characterized by a deficiency of C1 esterase inhibitor.An eight-year-old girl showed periorbital painless swelling, diagnosed as ethmoiditis. A craniofacial scan did not evidence a paranasal sinus involvement, C1INH levels were undetectable, with low C4 levels: 7.6 mg/dl and C1INH: <8.46 mg/dl. The genetic study identified a rare mutation of the C1INH gene. This clinical report is of relieve because paediatric cases described in literature are rare, did not presented a positive family history, and received a diagnosis after many attacks. Furthermore our girl received a prompt diagnosis of HAE at the first attack of angioedema.

Severe Labial Agglutination Release in a Postmenopausal Woman  [PDF]

Abstract: Labial agglutination occurs when the labia minora have become fused in the midline through either filmy or dense adhesions, forming a raphe. This condition is typically seen in pre-pubertal girls; however, there have been cases reported in the literature of labial agglutination in postmenopausal and reproductive aged women. Labial agglutination has been associated with local irritation and inflammation in the setting of a hypoestrogenic state. Topical treatment is usually recommended prior to manual separation. However, some postmenopausal women have been refractory to conservative management, and surgery may then be required. We present a case of a 79-year-old Caucasian gravida 3 para 3 who was referred for treatment refractory labial agglutination for 3 years. The patient’s complaints included a small trickle escaping from the introitus during urination and the sensation of little urinary control. The patient underwent an exam under anesthesia. Gentle blunt dissection with a lacrimal dilator easily separated the labia minora down the visible midline fusion line (raphe). Bimanual exam then revealed a 12-week-sized enlarged uterus confirmed on ultrasound to be an 8 × 8 × 7 cm irregular mass concerning for uterine cancer. Proceeding to an operative release of severe labial agglutination can relieve patient discomfort and frustration when estradiol therapy has failed. In addition to alleviating symptoms, releasing labial agglutination can also provide the gynecologist access to critical screening procedures such as cervical cytology or a bimanual exam, all of which could lead to a diagnosis or pre-cancerous or cancerous lesions.
Transposon Tn7 Preferentially Inserts into GAA?TTC Triplet Repeats under Conditions Conducive to Y?R?Y Triplex Formation

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0011121
Abstract: Expansion of an unstable GAA?TTC repeat in the first intron of the FXN gene causes Friedreich ataxia by reducing frataxin expression. Structure formation by the repeat has been implicated in both frataxin repression and GAA?TTC instability. The GAA?TTC sequence is capable of adopting multiple non-B DNA structures including Y?R?Y and R?R?Y triplexes. Lower pH promotes the formation of Y?R?Y triplexes by GAA?TTC. Here we used the bacterial transposon Tn7 as an in vitro tool to probe whether GAA?TTC repeats can attract a well-characterized recombinase.
Georeferenced cartography dataset of the La Fossa crater fumarolic field at Vulcano Island (Aeolian Archipelago, Italy): conversion and comparison of data from local to global positioning methods

Annals of Geophysics , 2011, DOI: 10.4401/ag-4941
Abstract: The present study illustrates the procedures applied for the coordinate system conversion of the historical fumarole positions at La Fossa crater, to allow their comparison with newly acquired global positioning system (GPS) data. Due to the absence of ground control points in the field and on both the old Gauss Boaga and the new UTM WGS 1984 maps, we had to model the transformation errors between the two systems using differential GPS techniques. Once corrected, the maps show a residual Easting shifting, due to erroneous georeferencing of the original base maps; this is corrected by morphological comparative methods. The good correspondence between the corrected positions of the historical data and the results of the new GPS survey that was carried out in 2009 highlights the good quality of the old surveys, although they were carried out without the use of accurate topographical instruments.
