Dysplasia grading is widely used to assess risk of transformation in oral potentially malignant disorders despite limited data on predictive value. DNA ploidy analysis has been proposed as an alternative. This study examines the prognostic value for both tests used in a routine diagnostic setting to inform clinical management. A retrospective study of conventional dysplasia grading was conducte...

The CO2 laser was invented in 1963 by Kumar Patel. Since the early 1970s, CO2 laser has proved to be an effective method of treatment for patients with several types of oral lesions, including early squamous cell carcinoma.Laser surgery of oral premalignant disorders is an effective tool in a complete management strategy which includes careful clinical follow-up, patient education to eliminate ...

BACKGROUND Bone marrow examination is regarded as one of the most important diagnostic procedure to assess various haematological disorders. The uses and advantages of bone marrow aspiration are numerous. This study was conducted with the aim to evaluate the frequency of involvement of bone marrow with malignant and non-malignant haematological and other clinical disorders and to observe the si...

The aim of this study was to assess the accuracy of clinical diagnosis for lip lesions based on sensitivity and specificity. The retrospective analysis focused on the detection of lesions caused by potentially malignant disorders (PMDs) and malignant lesions (n = 1195). All cases were classified as benign, PMD, and malignant lesions. Concordance between diagnoses based on clinical examination a...

BACKGROUND Oral cancers can be preceded by clinically evident oral potentially malignant disorders (OPMDs). The current study evaluated the rate and the time of malignant transformation in the various OPMDs in a cohort of patients from southern Taiwan. Parameters possibly indicative for malignant transformation of OPMDs, such as epidemiological and etiological factors, and clinical and histopat...

Presence of fever in psychiatric patients may signify a number of potentially fatal conditions. Several of these are related to treatments (e.g. neuroleptic malignant syndrome with antipsychotics, serotonin syndrome with serotonergic antidepressants, and malignant hyperpyrexia with anaesthesia used for administration of electroconvulsive therapy) or exacerbated by them (e.g. malignant catatonia...

Materials and methods In this prospective study, a total of 147 consecutive patients with potentially malignant disorders were treated with surface illumination PDT, using 5-ALA or mTHPC as the photosensitiser. The average age was 53±8.9 years. Patients’ recovery was uneventful and no complications reported. Comparisons with the clinical and histopathological features and rate of recurrence as ...

Prostate cancer is the most common malignant tumor in men. The vast majority of prostate tumors are represented by prostatic adenocarcinomas (up to 95%). Sarcoma a very rare adults with formidable prognosis. Early diagnosis and radical surgery offer patients best chance cure. We report case 44-year-old patient stage VI unresectable high-grade undifferentiated sarcoma, initially presenting urina...

18-Fluoredeoxyglucose position emission tomography and computed tomography (F-18FDG PET/CT) scanning has been useful in the evaluation of malignant disorders and has been extensively used in cancer screening. However, F-18FDG uptake was not found to be specific for cancer diagnosis. Here, we describe increased F-18FDG uptake on PET/CT caused by extensive tuberculous lymphadenitis in a 62-year-o...

A case of neonatal leukaemia of acute myeloid cell type was diagnosed at age 8 weeks and the patient died shortly afterwards with evidence of disseminated intravascular coagulation. An aneuploid malignant cell line 47, XY+C was found, in addition to the infant's normal constitutional karyotype. Eight other cases of congenital or neonatal leukaemia with aneuploid malignant cell lines are reviewe...
