Role of radiology in central hemangioma of jaws

2010

Central hemangioma, a bone destructive lesion, is a benign tumor. Hemangiomas of jaws are rare entity and produ- ces many different radiographic images. Radiographic differential diagnosis includes osteosarcoma, fibrous dysplasia, central giant cell granuloma, ameloblastoma, odontogenic myxoma, multiple myeloma, dentigerous cyst and aneurysmal bone cyst. Since it involves proliferation of blood vessels so aspiration or biopsy of such lesions can lead to severe hemorrhage which can turn out to be lethal. We stress on the importance of radiology in the timely diagnosis of such lesions which can prevent the disaster not only to the patient but also to oral surgeon in legal and professional asp…

Farbduplexsonographische Messung der Lymphknotenperfusion: Ein Beitrag zur Diagnostik der zervikalen Metastasierung*

1993

The objective of this study was to find additional sonomorphological criteria for determining the status of enlarged lymph nodes. By using colour-coded duplex sonography the perfusion of 63 lymph nodes in the neck was analysed. The status was confirmed either histologically or clinically (29 metastases from squamous cell carcinomas and 34 acute or chronic inflammatory nodal diseases). A quantitative evaluation of the pulsatility measured in 51 lymph nodes by computing the Pourcelot-Ratio and the Mean Pulsatility Index yielded significant differences between the two groups. By definition of a limiting value of the Pourcelot-Ratio (0.75) for the prediction of benignity, the specificity and th…

Oral hygiene instructions and professional control as part of the treatment of desquamative gingivitis. Systematic review

2019

Background The aim of this present article was to evaluate the scientific evidence on the efficacy of daily hygiene and professional prophylaxis for treatment of desquamative gingivitis. Material and Methods The present systematic review was conducted following the PRISMA protocol. Searches were carried out in Pubmed, Embase, Web of Science and Cochrane Library up to July 2018, randomized clinical trials and cohort studies on desquamative gingivitis (DG), and oral diseases joined to DG. Results After screening, we found that nine publications met the eligibility criteria eight cohort studies and one randomized control trial. The diagnosis of the diseases corresponded to oral lichen planus (…

Rectal bleeding and prolapse… not always benign diseases rather anal cancer. The importance of a correct decision making since primary care

2016

Rectal bleeding is very common in general population with a prevalence of 10-20 %. Primary care physicians have to stratify patients basing on urgency and on the colo-rectal cancer risk and to conduct a decision making for the correct management. We report a case of a 61-years-old woman, complaining rectal bleeding and an anal mass attended to their family doctor who does a visit but without a digital rectal examination and diagnosed a hemorrhoidal prolapse suggesting medical therapy. For the persistence of symptoms she comes to our service from emergency attention. Inspection and digital rectal examination revealed an anal mass. CT scan was performed showing a large anal mass involving hal…

Prevalence of oral mucosal lesions in a brazilian military police population.

2014

Background Data obtained from oral health surveys are very important for identifying disease-susceptible groups and for developing dental care and prevention programs. So, the purpose of the current article was to investigate the prevalence of oral mucosa lesions (OMLs) in a population of Brazilian police. Material and Methods Interviews and oral cavity examinations were performed on a sample of 395 police officers who were randomly selected by the calibrated researcher. The number of individuals was obtained by a sample calculation using the finite population correction. The diagnostic criteria were based on the WHO (1997) criteria and adapted to Brazilian surveys. Results In total, 8.61% …

Primary Extracranial Meningiomas of the Head and Neck

2021

Meningiomas represent the most common benign histological tumor of the central nervous system. Usually, meningiomas are intracranial, showing a typical dural tail sign on brain MRI with Gadolinium, but occasionally they can infiltrate the skull or be sited extracranially. We present a systematic review of the literature on extracranial meningiomas of the head and neck, along with an emblematic case of primary extracranial meningioma (PEM), which provides further insights into PEM management. A literature search according to the PRISMA statement was conducted from 1979 to June 2021 using PubMed, Web of Science, Google Scholar, and Scopus databases, searching for relevant Mesh terms (primary …

Detection of benign hilar bile duct stenoses – A retrospective analysis in 250 patients with suspicion of Klatskin tumour

2016

Introduction The aim of this study was to identify clinical, laboratory and radiological parameters to distinguish benign from malignant stenoses of the proximal bile duct. Methods Between 1997 and 2011, 250 patients were referred to our clinic with hilar bile duct stenoses suspicious for Klatskin tumour. Medical histories, clinical data, pre-interventional laboratory tests, imaging findings, as well as therapeutic approach and patient outcome were compared to final histological results. All data were retrieved from our prospectively maintained database and analysed retrospectively. Results We found benign bile duct lesions in 34 patients (13.6%). Among the entire study population, uni- and…

Organerhaltende Chirurgie des Nierenzellkarzinoms: Operative Technik, Ergebnisse, Komplikationen

2008

Abstract Operative method, course and complications were analysed retrospectively in 120 patients in whom a kidney tumour had been resected without nephrectomy. In 49 patients (18 women and 31 men, mean age 59 [38-77] years; 45 renal-cell carcinomas, 4 benign renal tumours) there was an "imperative indication" for an organ-preserving operation, because nephrectomy would have made dialysis obligatory. In 74 patients with a healthy contralateral kidney (25 women, 49 men, mean age 55 [31-74] years; 61 renal-cell carcinomas, 13 benign tumours) the tumour was enucleated by choice; 55 of these patients were symptom-free. 36 of 49 patients with an imperative indication are without sign of tumour p…
