Dental implants after the use of bichat’s buccal fat pad for the sealing of oro-antral communications. A case report and literature review

Oro-antral communications are frequent complications in oral surgery, and generally occur after molar extractions, maxillary sinus elevations or dental implant procedures. The presence of these defects may increase the morbidity and often need a surgical approach. The present report describes an oro-antral communication in a 52-year-old female who presented a 2 week-course of painless nasal obstruction and rhinorrea after a right maxillary sinus floor elevationwith simultaneous dental implant placement. Based on the anamnesis, clinical examination and a computed tomographyof the paranasal sinuses, a diagnosis of odontogenic rhinosinusitis associated with a 1.5 cm diameter oro-antral communicationwas establishedand its surgical closure using Bichat’s buccal fat pad was planned.After 15 months, the patient was successfully rehabilitated with an implant-supported 3 unit fixed partial denture

Vertebral carcinomatosis eleven years after advanced gastric cancer resection: A case report.

Bone metastasis is an uncommon event in advanced gastric cancer patients and bone metastases are rarely detected as isolated lesions. However, eleven years after treatment for locally advanced gastric cancer, including total gastrectomy followed by adjuvant chemotherapy, a 49-year-old female was admitted to the IX Division of General Surgery of the Second University of Naples (Naples, Italy) exhibiting severe progressive neurological symptoms. Magnetic resonance imaging indicated vertebral abnormalities, with evidence of marrow infiltration in several vertebral bodies; however, a contrast-enhanced computed tomography scan did not detect disease progression to other sites. Biopsy of the soft tissue at the level of the second lumbar vertebra (L2) revealed a metastatic lesion derived from gastric mucinous adenocarcinoma. The patient was initially treated with radiotherapy directed to the L2-L4 vertebral bodies to control the pain. Subsequently, systemic chemotherapy according to a FOLFOX-4 (leucovorin, fluorouracil and oxaliplatin) regimen commenced. However, after eight cycles, pulmonary progression of the disease occurred. Thus, palliative care was administered and the patient succumbed one month later. The late relapse of gastric cancer in the current patient may be associated with the theory of tumour dormancy

Rethinking the extrinsic incubation period of malaria parasites

The time it takes for malaria parasites to develop within a mosquito, and become transmissible, is known as the extrinsic incubation period, or EIP. EIP is a key parameter influencing transmission intensity as it combines with mosquito mortality rate and competence to determine the number of mosquitoes that ultimately become infectious. In spite of its epidemiological significance, data on EIP are scant. Current approaches to estimate EIP are largely based on temperature-dependent models developed from data collected on parasite development within a single mosquito species in the 1930s. These models assume that the only factor affecting EIP is mean environmental temperature. Here, we review evidence to suggest that in addition to mean temperature, EIP is likely influenced by genetic diversity of the vector, diversity of the parasite, and variation in a range of biotic and abiotic factors that affect mosquito condition. We further demonstrate that the classic approach of measuring EIP as the time at which mosquitoes first become infectious likely misrepresents EIP for a mosquito population. We argue for a better understanding of EIP to improve models of transmission, refine predictions of the possible impacts of climate change, and determine the potential evolutionary responses of malaria parasites to current and future mosquito control tools

2012, "Job creation and job destruction in the presence of informal markets

Abstract Recessions and policy interventions in labour markets in developing countries are characterized not only by changes in the unemployment rate, but also by changes in the proportion of formal or protected jobs. This reallocation between formal and informal jobs is large and occurs mainly because the job …nding rate of formal jobs reacts substantially more than the job …nding rate of informal jobs. This paper presents a search and matching model to capture this fact. I assume that …rms operate the within …rm margin of formality, choosing to legalize only those matches that are good enough to compensate the costs of formality. In this framework, recessions or stricter regulations in the labour market trigger two e¤ects. As expected, they lower the incentives to post vacancies (meeting e¤ect), but also a¤ect the …rms'hiring standards, favouring informal contracts (o¤er e¤ect). This new channel sheds light on how the actions of policy makers alter the outcomes in an economy with informal jobs. For instance, attempts to protect employment by increasing …ring costs will reallocate workers to informal jobs, where job separation is high. They are also likely to increase unemployment.

Subclinical Systemic Sclerosis Primary Heart Involvement by Cardiovascular Magnetic Resonance Shows No Significant Interval Change

Objective Subclinical systemic sclerosis (SSc) primary heart involvement is commonly described. Whether these findings progress over time is not clear. The study aimed to investigate cardiovascular magnetic resonance (CMR) interval change of subclinical SSc primary heart involvement. Methods Patients with SSc with no cardiovascular disease underwent two CMR scans that included T1 mapping and quantitative stress perfusion. The CMR change (mean difference) and association between CMR measures and clinical phenotype were assessed. The study had a prospective design. Results Thirty-one patients with SSc participated, with a median (interquartile range) follow-up of 33 (17-37) months (10 [32%] in the diffuse subset, 16 [52%] with interstitial lung disease [ILD], and 11 [29%] who were Scl-70+). Four of thirty-one patients had focal late gadolinium enhancement (LGE) at visit 1; one of four had an increase in LGE scar mass between visits. Two patients showed new focal LGE at visit 2. No change in other CMR indices was noted. The three patients with SSc with increased or new LGE at visit 2 had diffuse cutaneous SSc with ILD, and two were Scl-70+. A reduction in forced vital capacity and total lung capacity was associated with a reduction in left ventricular ejection fraction (ρ = 0.413, P = 0.021; ρ = 0.335, P = 0.07) and myocardial perfusion reserve (MPR) (ρ = 0.543, P = 0.007; ρ = 0.627, P = 0.002). An increase in the N-terminal pro–brain natriuretic peptide level was associated with a reduction in MPR (ρ = −0.448, P = 0.042). Patients on disease-modifying antirheumatic drugs (DMARDs) had an increase in native T1 (mean [SD] 1208 [65] vs. 1265 [56] milliseconds, P = 0.008). No other clinically meaningful CMR change in patients receiving DMARDs or vasodilators was noted. Conclusion Serial CMR detects interval subclinical SSc primary heart involvement progression; however, this study suggests abnormalities remain largely stable with follow-up

巨大災害研究センターでは、所員それぞれの研究テーマ以外に、センター全体に関わる活動を継続し、研究成果のアカウンタビリティの向上に貢献している。本年は、1)巨大災害研究センターセミナー、2)第12回地域防災計画実務者セミナー、3)災害対応研究会、4)第7回比較防災ワークショップ、5)データベース「SAIGAI」、について内容を紹介する。The objectives of this paper are to summarize the research activities of Research Center for Disaster Reduction Systems, DPRI. They are systematically organized by not only our staff members but also many researchers and practitioners who do voluntary work in some workshops and symposia. Open symposia were held monthly with large audience. The 12th Seminar for Regional Disaster Prevention Plan was held focusing on the civil protection planning. The 7th Workshop on Comparative Disaster Studies was held to provide an integrated review of the Japanese efforts to reduce vulnerability of the world, and to discuss reconstruction both in United States and Japan. We are also upgrading and expanding the database SAIGAI
