Cutaneous radiation syndrome has severe long-term health consequences. Because it causes an unpredictable course of inflammatory waves, conventional surgical treatment is ineffective and often leads to a fibronecrotic process. Data about the long-term stability of healed wounds, with neither inflammation nor resumption of fibrosis, are lacking. In this study, we investigated the effect of injections of local autologous bone marrow-derived mesenchymal stromal cells (BM-MSCs), combined with plastic surgery for skin necrosis, in a large-animal model...

REVIEW
Shawn Shih, Amor Khachemoune
Acquired digital fibrokeratoma (ADFK) is a rare, benign, fibrous tumor that most often occurs on fingers. It may resemble a rudimentary supernumerary digit and is often misdiagnosed as another common benign condition, such as common wart. It is typically asymptomatic and occurs as a solitary nodule less than 1 cm in diameter. Oftentimes ADFK shares clinical and/or histologic resemblance with other benign and malignant cutaneous conditions so it is crucial that careful examination is undertaken. In this article, we will discuss the clinical presentation, epidemiology, etiology, dermoscopic and histologic findings, management, and differential diagnoses for ADFK, with the hope that this review will facilitate timely diagnosis and management for this distinct condition...

Primary cutaneous extraskeletal osteosarcoma (PCEO) is a rare malignant neoplasm with less than 20 cases reported in the literature to date. Presenting as a nodule or mass on the skin, commonly at sites of previous trauma or radiation, these lesions are differentiated from other neoplasms through their characteristic microscopic appearance. This report highlights a case of PCEO in a 75-year-old man with a history of squamous cell carcinoma (SCC) of the scalp. Histological examination of a scalp nodule in the region of a previously excised SCC revealed proliferation of osteoid surrounded by malignant osteocytes...

A 1-y-old spayed female ferret (Mustela putorius furo) was referred for additional diagnostic evaluation after physicalexamination by the referring veterinarian revealed a cranial abdominal mass. The ferret had a 2-wk history of inappetence,weight loss, and lethargy. On presentation, the ferret was thin, and an approximately 3-cm mass was palpable in the cranialabdomen. No other abnormalities were noted. Abdominal ultrasonography confirmed the presence of a soft-tissue structure, with a moderate blood supply and mesenteric lymphadenopathy...

INTRODUCTION: Low-dose computed tomography (LDCT) lung cancer screening is recommended in the United States. While new solid nodules after baseline screening have a high lung cancer probability at small size and require lower size cutoff values than baseline nodules, there only is limited evidence on management of new subsolid nodules. METHODS: Within the Dutch-Belgian randomized controlled LDCT lung cancer screening trial (NELSON), 7557 participants underwent baseline screening between April 2004 and December 2006...

The role of local treatment in patients with oligometastatic non-small-cell lung cancer (NSCLC) is a subject of ongoing debate. This study assessed the survival impact of combined surgery to the primary tumor and metastatic disease in the management of metastatic NSCLC. Stage IV NSCLC patients at presentation, diagnosed from 2004 to 2013 were identified from the SEER (Surveillance, Epidemiology, and End Results) database. Propensity-matched analysis was performed considering baseline characteristics (age, gender, race, histology, TN stage, and site of metastases)...

Plexiform schwannoma is an extremely rare variant of schwannoma, accounting for approximately 5% of cases. Due to the rarity and lack of typical symptoms, signs and radiological images, a definite diagnosis of plexiform schwannoma may not be made by clinicians prior to biopsy. In the present study, we report the first case (to our knowledge) of perianal plexiform schwannoma arising from the overlapped skin of the ischioanal fossa, and we propose an intratumorally nonenhanced circumferential capsule dividing the tumour into multiple homogeneously enhanced nodules as a magnetic resonance imaging feature to aid in the differential diagnosis of plexiform schwannoma from ancient schwannoma, cavernous haemangioma, liposarcoma and plexiform neurofibroma...

Peanut ( Arachis hypogaea L.), an important leguminous crop, is widely cultivated in tropical and subtropical regions. Peanut is an allotetraploid, having A and B subgenomes that maybe have originated in its diploid progenitors Arachis duranensis (A-genome) and Arachis ipaensis (B-genome), respectively. We previously sequenced the former and here present the draft genome of the latter, expanding our knowledge of the unique biology of Arachis . The assembled genome of A. ipaensis is ~1.39 Gb with 39,704 predicted protein-encoding genes...

Titanium (Ti) and Ti-6 Aluminium-4 Vanadium alloys are the most common materials in implants composition but β type alloys are promising biomaterials because they present better mechanical properties. Besides the composition of biomaterial, many factors influence the performance of the biomaterial. For example, porous surface may modify the functional cellular response and accelerate osseointegration. This paper presents in vitro and in vivo evaluations of powder metallurgy-processed porous samples composed by different titanium alloys and pure Ti, aiming to show their potential for biomedical applications...

Research focused on transforming growth factor β (TGFβ) signaling in osteoblast is gradually increasing, whereas literature is rare in terms of fluorosis. This work aimed to investigate how TGFβ signaling participated in regulation of the osteoblast by different doses of fluoride treatment. Bone marrow stem cells (BMSCs) were developed into osteoblastic cells and exposed to 1, 4, and 16 mg/L F- with and without 10 ng/mL of TGFβ. Cell viability and differentiation state of osteoblast under different settings were measured by means of cell counting kit and analysis of alkaline phosphatase (ALP) activity as well as formation of mineral nodules...

Thyroid nodules are a common finding in general population, with a prevalence of 20% to 70% at ultrasound (US) examination. Many of them are benign but treatment can be necessary to relief compressive symptoms. In the last years, percutaneous ablations have achieved amazing development in the treatment of thyroid nodules as they provide a minimally invasive but effective approach. We aimed to summarize the main aspects related to treatment of thyroid nodules with radiofrequency ablation (RFA), focusing on the use of different types of needles...
