A pig model of hepatic cryotherapy. In vivo temperature distribution during freezing and histopathological changes
2003
We aimed to assess the temperature distribution in the cryolesion during hepatic cryotherapy and the association with postoperative histological changes to optimise the technique and allow better preoperative planning. Hepatic cryolesions were produced in 22 pigs following laparotomy using a CMS-cryosystem and 8mm-AccuProbe-Cryoprobes. The temperature was measured in 1 min intervals at different distances from the probe during freezing. The animals were treated in 5 groups: (i) single freezing of 20 min; (ii) double freezing of 20 min each; (iii) single freezing of 40 min; (iv) single freezing of 20 min (n=4), histology at 1 week p.o., and (v) single freezing of 20 min and Pringle manoeuvre…
Simple bone cyst : a case report
2021
Background Simple bone cysts (SBC) are intraosseous cysts devoid of an epithelial lining, asymptomatic and appearing in the jaw. In general, SBCs are discovered incidentally and tooth displacement or pathological fractures are very unusual. Material and methods This study reports a 16 years old man that presented an asymtomatic radiolucent unilocular lesion in the right ascending ramus. Differencial diagnosis included odontogenic keratocyst and dentigerous cyst. One surgical intervention was performed and consisted in the curettage of the bone walls. The lesion and some small samples of the bone wall were sent for the anatomopathological study. Results The anatomopathological exam confirmed…
Juvenile central ossifying fibroma of the mandible: a case report
2010
Central ossifying fibroma is a rare fibro-osseous neoplasm in young children. It is highly aggressive and has a strong tendency to recur. We describe an 11-year-old girl with juvenile central ossifying fibromas of the mandible that caused obstruction of tooth eruption of the lower left second premolar. Oral examination revealed the presence of the primary lower left second molar and a small bony hard swelling over the left side of the mandibular body. After a computed tomographic scan, an incisional biopsy was performed, and the lesion proved to be a juvenile ossifying fibroma. Although this tumor often recurs early, and many authors suggest radical en bloc resection, we performed a more co…
Osteomyelitis affecting mandible in tuberculosis patients
2012
Tuberculosis (TB) is a frequent health problem in developing nations. It has two forms pulmonary and secondary causing other kinds of TB, collectively denoted extra pulmonary tuberculosis. The prevalence of extra pulmonary TB has increased in the last couple of years. Maxillofacial manifestations of tuberculosis form nearly 10% of all extra pulmonary manifestations of the disease. Extra pulmonary TB involving maxillofacial region is our prime concern. Very few cases of TB of the temporomandibular joint (TMJ) and mandible have been reported in literature. The clinical appearance of TB infection of the TMJ has been described as unspecific, resembling arthritis, osteomyelitis, cancer or any ki…
0200: Predictors of angiographically visible distal embolization in ST elevation myocardial infarction patients treated by primary percutaneous coron…
2016
Aspiration thrombectomy during primary percutaneous coronary intervention (p-PCI) in ST elevation myocardial infarction (STEMI) has been proposed to restore myocardial reperfusion. But important controversies remain concerning the usefulness of thrombectomy to improve this perfusion. Our objective was to evaluate the impact of manual thrombectomy on the occur-rence of angiographically visible distal embolization (AVDE) during p-PCI in STEMI. 346 consecutive patients admitted for STEMI who underwent p-PCI and thrombectomy were included. Clinical, angiographic and therapeutics characteristics were assessed. AVDE was defined as an abrupt vessel closure occurring at any point during the PCI pro…
Vaginohysteroscopy for the diagnosis and treatment of vaginal lesions.
2016
Abstract Background The vaginoscopic approach for hysteroscopy allows detailed endoscopic evaluation of the vaginal walls, fornices, and exocervix. Objectives To review the feasibility and efficacy of vaginohysteroscopy in the diagnosis and treatment of vaginal lesions. Search strategy A systematic review was performed of PubMed/Medline, Embase, Google Scholar, and the Cochrane Database to identify papers published in English. The search terms were “hysteroscopy,” “vaginoscopy,” “vagino-hysteroscopy,” and “vaginal lesion.” The last review was performed on January 31, 2015. Selection criteria Studies in which the diagnosis and treatment of vaginal lesions used the vaginoscopic approach and h…
Laserfotokoagulation und photodynamische Therapie (PDT) zur Behandlung der retinalen angiomatösen Proliferation (RAP) bei feuchter altersabhängiger M…
2008
BACKGROUND: Retinal angiomatous proliferation (RAP) is a subtype of neovascular age-related macular degeneration (AMD) with particularly bad prognosis. Diverse treatment modalities are performed. PATIENTS AND METHODS: This is a retrospective review on the treatment results of 41 consecutive patients from 1 / 2003 to 12 / 2005 with RAP stage 1 - 3 (Yannuzzi classification), who were treated with laser photocoagulation, photodynamic therapy (PDT) and intravitreal injection of triamcinolone acetonide (IVT). Follow-up was 12 months minimally. RESULTS: In RAP stage I complete closure of the vascular lesion in 14 / 22 eyes was achieved by 1.2 ± 0.5 sessions of laser photocoagulation (4 × combined…
Photobiomodulation therapy for the management of recurrent aphthous stomatitis in children : clinical effectiveness and parental satisfaction
2020
Background This study aims to evaluate the effectiveness of the photobiomodulation therapy (PBMT) in the treatment of minor recurrent aphthous stomatitis (MiRAS) in children, in terms of pain relief, lesion size reduction and the parental satisfaction of the therapy. Material and Methods This randomized controlled study was carried out on 60 children with clinical diagnosis of MiRAS. Patients were randomized into two groups: group A receiving laser therapy and group B receiving sham therapy (placebo). Laser therapy (diode laser, λ: 645 nm) was administered on day 1 (T0) for three consecutive days. Patients were evaluated also on day 4 (T1), on day 7 (T2) and on day 10 (T3). Oral aphthous le…

Embolization with ethylene vinyl alcohol copolymer (Onyx®) for peripheral hemostatic and non-hemostatic applications: a feasibility and safety study
2018
International audience; Background: Onyx® is a liquid embolic agent, which is approved for the treatment of cerebral vascular lesions but still rarely used in peripheral interventional radiology. The goal of this study is to report the feasibility and safety of embolization with Onyx® for peripheral hemostatic and non-hemostatic endovascular procedures.Methods: Retrospective study of all consecutive patients who underwent visceral or peripheral embolization with Onyx® for hemostatic or non-hemostatic purpose in our department between May 2014 and November 2016. Demographic data, clinical presentation, underlying etiology, culprit vessel, endovascular procedure, pain during embolization, out…
