Alterations of panoramic radiomorphometric indices in children and adolescents with beta-thalassemia major: A fractal analysis study

2021

Background Beta-thalassemia major is an inherited disorder that can cause bone deformity and loss of bone mineral density. The objective of this study is to evaluate the cortical and trabecular mandibular bone morphology of children and adolescents who have beta-thalassemia major (ß-TM) using a fractal dimension (FD) analysis and different panoramic radiomorphometric indices with digital panoramic radiographic images (DPRIs). Material and Methods The study included 80 patients (with 40 patients each of ß-TM and control). The mandibular cortical width (MCW), panoramic mandibular index (PMI), mandibular cortical index (MCI), and simple visual estimation (SVE) were evaluated, and an FD analysi…

Recurrent intussusception of small bowel in a young patient due to metastases from cardiac undifferentiated pleomorphic sarcoma: A first ever case re…

2020

Highlights • Metastatic undifferentiated pleomorphic sarcoma (Malignant Fibrous Histiocytoma) is a rare entity in the visceral organs. • We report a case of a metastatic primary cardiac undifferentiated pleomorphic sarcoma which presented with a recurrent small bowel intussusception in a young man. • Laparotomy by a small midline incision performed on the same day identified an intussusception of a 15-cm section of small intestine caused by a 4-cm intraluminal metastasis from undifferentiated pleomorphic sarcoma. • Metastasis intussusception in the small intestine is a very rare condition and they are part of differential diagnosis in patient with a history of tumor who present with intussu…

Malignant paroxysmal positional vertigo

2011

Objective: An insidious percentage of paroxysmal positional vertigo appears to be intractable with canalith repositioning maneuver and also is not self-limiting. This type of positional vertigo is sustained by the action of intracranial tumors that mimics the clinical aspects of benign paroxysmal positional vertigo.Aim of this study is to clarify the features of these forms of positional vertigo, which we indicate as malignant paroxysmal positional vertigo. Methods: We retrospectively reviewed the clinical records of all the patients who presented with vertigo spells and were managed at our tertiary care referral centre over a three years period. Two hundred and eleven patients with diagnos…

Oral Lichen Planus : risk factors of malignant transformation and follow up. Ten years retrospective study

2020

Background Oral Lichen Planus (OLP) is an inflammatory chronic disease. Modified World Health Organization (WHO) diagnostic criteria (2003) suggest diagnosing OLP both clinically and histologically. Furthermore, it is known the potential of malignant transformation of OLP, especially those affecting mucosa. Aims of this retrospective study on 100 patients were i) to estimate the timing of transformation of OLP lesions in OSCC in a cohort of patients observed between 2008 and 2018; ii) to assess risk factors of OLP patients diagnosed with OSCC; iii) to analyse forms of OLP evolved in cancer. Material and methods A database of 100 patients diagnosed with OLP was evaluated and clinical, histol…

Grenzen der Indikation zur Intensivtherapie bei chirurgischen Patienten — Prospektive Untersuchung zur Bedeutung von Scores (APACHE II, HIS, TISS) un…

1993

The aim of the study was to describe the objective factors (clinical values, scores, basic and concomitant illnesses) that could possibly justify the omittance of intensive therapy. In a prospective study in 169 postoperative intensive therapy patients, it was shown that scores (APACHE II, HIS, TISS) serum-lactate and serum creatinine were significant prognostic parameters for lethal outcome, while these parameters had no effect on the prognosis after patients were discharged. Primarily, the presence of a malignant disease and/or the age of the patient were decisive. By considering these factors for lethal outcome and long-term prognosis, it is possible to identify patients who do not benef…

Online audio-visual information on oral cancer for Spanish-speaking laypersons. A cross-sectional study

2021

Background Lack of knowledge and awareness of oral cancer seem to be the main causes of diagnostic delay. Online resources are often used by patients to obtain health/medical information. However, there are no reports on the quality and usefulness of oral cancer audio-visual resources in Spanish. The aims of this investigation were to disclose the type of information about oral cancer available, and whether it may be useful to shorten the patients’ oral cancer appraisal time-interval. Material and Methods Cross-sectional study undertaken at three video-sharing sites on October, 13th 2019. Keywords: “Cáncer oral”; “cáncer de boca”. The first 100 results in each viewing list were retrieved by…

Malignant metastatic melanoma to the gallbladder: Report of a peculiar case

2020

Highlights • Melanoma is one of the most aggressive and one of the fastest growing types of cancer. The gallbladder envolvement from a metastatic cutaneous malignant melanoma is a highly uncommon finding, usually associated with diffuse metastatic disease and observed during autopsy. • We report a case of a 35-years old Caucasian woman with isolated metastasis of gallbladder form cutaneous primary malignant melanoma underwent to laparoscopic cholecystectomy. • Malignant cutaneous melanoma is a skin cancer characterized by the highest mortality. Isolated metastasis of gallbladder are barely described and mostly present in a widespread metastatic disease. Surgical treatment is indicated consi…

Safety of high doses of somatostatin analogs in well differentiated NENs in elderly

2019

Abstract Background Neuroendocrine neoplasms (NENs) are a group of heterogeneous neoplasms which can be treated with different therapies: in well differentiated (WD) NENs analogs of somatostatin (SSA) can be used considering their proved antineoplastic and antisecretory effects. This is a multicenter study to investigate the safety of high doses (HDD) analogs of somatostatin (SSA) in WD NENs with particular attention for patients over 70 years of age. Methods We collected clinical data from 13 Italian NENs dedicated Units. Patients with WD NENs, in progression on previous treatments, included SSA, and subsequently treated with HDD-SSA, were considered. Results 170 pts were included: 61.76% …

A Rare Case of Primary Gastric Melanoma

2019

Abstract Primary melanomas in the gastrointestinal tract are extremely rare, with an estimated prevalence of 0.5 to 1 case per million. Primary mucosal melanomas of gastric origin account for approximately 1–3% of all primary melanomas in the gastrointestinal tract. We present the case of a patient who underwent surgery due to primary gastric melanoma.
