INTRODUCTION: Calcifying odontogenic cysts (COC) represent 0.3-0.8% of all odontogenic cysts. We describe the finding and the treatment of a COC in a 67-year-old female. OBSERVATION: An asymptomatic well-limited radioluscent mandibular lesion was fortuitously discovered on the panoramic X-ray in the periapical region of teeth No. 33 and 34. Treatment consisted in enucleation and curettage. Histologic examination was in favour of a COC. At 6 years follow-up, X-ray control showed new bone formation and the patient was free of symptoms...

To develop an effective and sustainable cell therapy for sickle cell disease (SCD), we investigated the feasibility of targeted disruption of the BCL11A gene, either within exon 2 or at the GATAA motif in the intronic erythroid-specific enhancer, using zinc finger nucleases in human bone marrow (BM) CD34(+) hematopoietic stem and progenitor cells (HSPCs). Both targeting strategies upregulated fetal globin expression in erythroid cells to levels predicted to inhibit hemoglobin S polymerization. However, complete inactivation of BCL11A resulting from bi-allelic frameshift mutations in BCL11A exon 2 adversely affected erythroid enucleation...

Prostate cancer can be diagnosed as an incidental finding during the pathological examination of benign prostatic hyperplasia (BPH) specimens by Holmium laser enucleation of the prostate (HoLEP). BPH and comorbidities such as hypertension, diabetes, and dyslipidemia often coexist in elderly people. We identified which comorbidities can be used to predict the presence of incidental prostate cancer, particularly high-risk cancer, in men who had undergone HoLEP. On the basis of pathological findings of HoLEP specimens, patients with incidental cancer were categorized as low-risk (Gleason ≤6 and T1a) or high-risk (all others)...

Amyloid precursor protein (APP) is essential to physiological processes such as synapse formation and neural plasticity. Sequential proteolysis of APP by beta- and gamma-secretases generates amyloid-beta peptide (Aβ), the main component of senile plaques in Alzheimer Disease. Alternative APP cleavage by alpha-secretase occurs within Aβ domain, releasing soluble α-APP (sAPPα), a neurotrophic fragment. Among other functions, sAPPα is important to synaptogenesis, neural survival and axonal growth. APP and sAPPα levels are increased in models of neuroplasticity, which suggests an important role for APP and its metabolites, especially sAPPα, in the rearranging brain...

BACKGROUND: Equine Recurrent Uveitis (ERU) is a common cause of ocular pain and blindness in horses. Leptospira spp. have commonly been implicated in the pathophysiology of ERU in mainland Europe and USA. No recent studies have been carried out in the UK but it is reported that Leptospira is not a major factor in the aetiology of ERU in the UK. OBJECTIVES: to establish the prevalence of Leptospira-associated ERU in the UK and identify the serovars involved in these cases in the UK; compare serum versus aqueous humour antibody levels in cases and controls in order to confirm the diagnosis of Leptospira-associated ERU; and assess the usefulness of serology alone as a confirmatory test for Leptospira-associated ERU in the UK...

Until the early 20(th)century enucleation of the eyeball or its partial excision were the basic treatments for ocular cancer. The discovery of X-rays by Wilhelm Conrad Röntgen (1845-1923) offered new possibilities to the treatment of ocular cancer either as mono or as adjuvant therapy. Nowdays this treatment is more sophisticated.

INTRODUCTION: We evaluate the clinical outcome of patients treated with conservative approach for small testicular masses (STMs). We analyzed the steps who brought to the selection of the therapeutic approach: starting from clinical presentation, through imaging and lab studies. METHODS: We considered 18 patients who underwent an organ-sparing approach for STMs from 2005 until 2014. The selection criteria were dimension of the mass and absence of clinical, laboratory and/or radiological malignancy suspicion...

REVIEW
Ross Cockrell, David I Lee
PURPOSE OF REVIEW: The leading cause of voiding dysfunction in older men is benign prostatic obstruction. In the setting of a grossly enlarged prostate (>80cm(3)), an open simple prostatectomy has been the gold standard for surgical treatment. Here, we will discuss the minimally invasive robot-assisted approach and compare it to the classic open approach and holmium laser enucleation of the prostate. RECENT FINDINGS: Literature on robot-assisted simple prostatectomy, in concurrence with our institutional experience, has shown an overall lower morbidity, shorter hospital stay, and decreased indwelling catheter time, with equivalent functional outcomes compared to open simple prostatectomy...

BACKGROUND: Neovascular glaucoma (NVG) is rare, comprising only 3.9% of all glaucoma cases. The most common cause of NVG is ischaemic central retinal vein occlusion (iCRVO). NVG frequently results in blindness and painful end-stage glaucomatous damage leading to the need for enucleation. Currently, there is no preventive therapy for NVG following iCRVO. Rescue treatments have severe drawbacks. Accordingly, there is a great need for preventing the often visually devastating outcomes of NVG...

BACKGROUND: Factor XI (FXI) deficiency (hemophilia C [HEM-C]) is a bleeding disorder with unpredictable severity that correlates poorly with FXI coagulation activity (FXI:C). It poses a perioperative hemostatic management challenge. For US patients with severe disease, fresh frozen plasma (FFP) or, in current use, thawed plasma is the most readily available option but comes with risk of volume overload. We report our experience of using therapeutic plasma exchange (TPE) as an alternative perioperative management strategy...
