Lipoma is the most common, benign, soft tissue, mesenchymal tumour and is composed of mature adipose tissue. It is infrequent in the oral cavity (approximately 0.3% of all tongue neoplasias). We describe the case of a 68-year-old man with a swelling at the tongue edge and tongue dysesthesia. Medical history, clinical assessment, radiographic images, and cytological analysis enabled specialists to classify this neoplasia as a lipoma. The patient recovered fully after surgical excision of the affected area, and the neuralgic symptoms regressed. Surgical excision is an elective treatment; however, accurate differential diagnosis, histological examination, and follow-up are required.

Stevens-Johnson syndrome (SJS) is characterized by mucocutaneous tenderness and typical hemorrhagic erosions, erythema and epidermal detachment presenting as blisters and areas of denuded skin. SJS is often observed after drug use as well as after bacterial or viral infections. Several drugs are at high risk of inducing SJS, but there are no cases in the English literature regarding anabolic steroid use triggering SJS. In our paper, we describe a case in which use of anabolic androgenic steroids (AAS) was associated with SJS. The patient participated in competitive body-building and regularly took variable doses of AAS. Initial symptoms (headache, weakness, pharyngodynia, and fever) were ignored. After a week he presented to the Emergency Department with a burning sensation on the mouth, lips, and eyes. Painful, erythematous, maculopapular, and vesicular lesions appeared all over the body, including on the genitals. During hospitalization, he also developed a cardiac complication. The patient had not taken any drugs except AAS.

Osteonecrosis of the jaw (ONJ) is commonly described as an adverse effect of the use of bisphosphonates. A few cases of ONJ associated with tyrosine kinase inhibitors (sunitinib, imatinib) have been reported in the literature and usually they occurred in patients simultaneously treated with bisphosphonates. We report an atypical case of ONJ related only to imatinib. A 72-year-old male patient was treated with imatinib for metastases from gastrointestinal stromal tumors (GISTs). The patient developed ONJ after 22 months of imatinib only therapy. During his whole life, the patient had never been treated with bisphosphonates or radiotherapy. Microscope examination of the tissues confirmed the clinical diagnosis of diffuse osteonecrosis and showed absence of neoplastic cells. Thus, secondary localisations from GISTs were ruled out. Osteonecrosis of the lower jaw appeared 22 months after initial and exclusive therapy with imatinib. Therefore, imatinib monotherapy can induce ONJ in patients that have never been treated with bisphosphonates or radiotherapy.

Bisphosphonates are drugs used to treat osteoclast-mediated bone resorption, including osteoporosis, Paget disease, multiple myeloma, cancer-related osteolysis, and malignant hypercalcemia. The use of these drugs has increased in recent years as have their complications, especially bisphosphonate-related osteonecrosis of the jaw (BRONJ), which more frequently affects the mandible. Here we report a case of BRONJ with a particularly unfavorable course due to cervical inflammation that developed into necrotizing fasciitis, followed by multiorgan involvement leading to septic shock and death.

Loss of E-cadherin, a 120 kDA transmembrane glycoprotein responsible for cell-cell adhesion, is one of the hallmarks of epithelial-mesenchymal-transition (EMT). E-cadherin expression was immunohistochemically studied in 94 histopathologically re-confirmed colorectal carcinomas (CRC) using a monoclonal antibody to E-cadherin (Dako: Clone NCH-38) on a Ventana Benchmark XT automated system. Each case was assessed for E-cadherin immunopositivity at two separate locations viz the tumour centre (TC) as well as the infiltrating front (IF). Expression was semiquantitated for proportion of immunopositive malignant cells as 0 (negative), 1 (1-25% staining), 2 (26-50% staining), 3 (51-75% staining) and 4 (>75% staining) and staining intensity: 0 (negative), 1 (weak), 2 (moderate) and 3 (strong). The final histoscore of E-cadherin immunopositivity was arbitrarily computed as proportion of immunopositivity multiplied by staining intensity of the malignant cells. E-cadherin histoscores were significantly lower at the IF (4.5 ± 2.5) compared with TC (10.7 ± 2.4). Furthermore, the histoscores were significantly reduced at the IF of 49 TNM III+IV tumours (3.6 ± 2.5) compared with 45 II+III CRC (5.4 ± 2.2). Reduction of E-cadherin expression was also noted in the 23 high grade (TC=8.6 ± 3.2; IF=2.6 ± 2.3) compared with 71 low grade tumours (TC = 11.4 ± 1.5; IF = 5.1 ± 2.3). E-cadherin is downregulated at the infiltrating front of CRC, possibly marking for EMT at this location. The downregulation is further enhanced amongst late stage and high grade tumours compared with earlier stage and low grade tumours; findings which are similar to that noted in CRC of other populations.

Stereotactic body radiotherapy (SBRT) represents a consolidated treatment option for patients with medically inoperable early stage non-small cell lung cancer (NSCLC). The clinical evidence accumulated in the past decade supports its use as an alternative to surgery with comparable survival outcomes. Due to its limited toxicity, SBRT is also applicable to elderly patients with very poor baseline pulmonary function or other severe comorbidities. Recent comparative studies in operable patients raised the issue of the possible use of SBRT also for this subgroup, with quite promising results that still should be fully confirmed by prospective trials with long-term follow-up. Aim of this review is to summarize and discuss the major studies conducted over the years on SBRT and to provide data on the efficacy and toxicity of this radiotherapy technique for stage I NSCLC. Technical aspects and quality of life related issues are also discussed, with the goal to provide information on the current role and limitations of SBRT in clinical practice.

OBJECTIVES: To determine the prevalence of incidental maxillary sinus findings in a large sample of orthodontic patients by cone-beam computed tomography (CBCT) with a wide field of view and assess the relationships of such abnormalities with age and gender. METHODS: Five hundred thirteen CBCT scans obtained for orthodontic diagnosis and treatment planning in a Northern Italian population (N = 513; 292 female and 221 male subjects; 1,026 maxillary sinuses) were studied. The frequencies of pseudocysts and mucosal thickening of the maxillary sinus were recorded. Logistic regression analysis was used to determine the influence of age and gender on these abnormalities. RESULTS: Pseudocysts were detected in 52 patients (10.1%) and 59 sinuses (5.75%). Mucosal thickening was observed in 206 patients (40.1%) and 258 sinuses (25.1%). Gender and age were significantly associated with pseudocysts (p = 0.027) and mucosal thickening (p < 0.001), respectively. CONCLUSIONS: Half of the orthodontic patients had incidental maxillary sinus findings. Men were more likely to show pseudocysts, and older patients (aged 41 - 60 years) were more likely to show mucosal thickening.

There has been a growing concern about obesity worldwide. We performed a review on the prevalence and trends of obesity among adults and children. We reviewed the data on the prevalence of adult obesity and being overweight from the Global Database on Body Mass Index on the World Health Organisation (WHO) Website and prevalence of children being overweight from the International Obesity Task Force website. Various databases were also searched for relevant reviews and these include PubMed, EMBASE, NHS CRD databases and Cochrane. The prevalence of obesity is high in many parts of the world. Generally, there is an increasing trend of prevalence of adult obesity with age. The peak prevalence is reached at around 50 to 60 years old in most developed countries and earlier at around 40 to 50 years old in many developing countries. Obesity is a major health concern. Appropriate strategies need to be adopted to tackle obesity which itself brings about significant disability and premature deaths. Further observation may be needed to see if the trend of prevalence abates or increases in the near future.
