Foetal infection by the Zika virus has been implicated in the exceptional rise in the number of mycrocephalic newborns recorded by the end of 2015 in Brazil. The mechanism by which this teratogenic effect is produced in the developing brain has not been entirely established. Very early in the outbreak, we addressed this question by evaluating available initial data from a gestational and post-natal clinical investigation in the Brazilian state of Pernambuco. The present study was undertaken to test the hypothesis that the subtractive dysmorphic brain malformations observed in Zika's microcephaly are primarily due to the massive induction of apoptosis of neuroprogenitor cells...

Sensorineural losses of hearing and vestibular sensation due to hair cell dysfunction are among the most common disabilities. Recent preclinical research demonstrates that treatment of the inner ear with a variety of compounds, including gene therapy agents, may elicit regeneration and/or repair of hair cells in animals exposed to ototoxic medications or other insults to the inner ear. Delivery of gene therapy may also offer a means for treatment of hereditary hearing loss. However, injection of a fluid volume sufficient to deliver an adequate dose of a pharmacologic agent could, in theory, cause inner ear trauma that compromises functional outcome...

(68)Ga-PSMA PET/CT scanning has been shown to be more sensitive than conventional imaging techniques in patients with prostate cancer. This prospective Australian multicenter study assessed whether (68)Ga-PSMA PET/CT imaging impacts on management intent in patients with primary or recurrent prostate cancer. Methods: Prior to undertaking (68)Ga-PSMA PET imaging, referring medical specialists completed a questionnaire detailing relevant demographic and clinical data as well as their proposed management plan. A separate follow up questionnaire was completed after the (68)Ga-PSMA PET/CT scan results were available to determine whether their management plan would change...

INTRODUCTION: There is a variety of tools being used in clinical practice for the prediction of weaning success from mechanical ventilation. However, their diagnostic performances are less than satisfactory. The purpose of this study is to investigate the value of serial changes in diaphragm function measured by ultrasound during the spontaneous breathing trial (SBT) as a weaning predictor. METHODS AND ANALYSIS: This is a prospective observational study conducted in a 10-bed medical emergency intensive care unit (EICU) in a university-affiliated hospital...

Tricuspid valve disease is a frequent condition but is currently undertreated. A limited number of patients undergo an isolated surgical tricuspid repair, and this intervention is associated with poor outcomes, especially in patients with previous cardiac surgery. Most patients are only medically treated, despite the impact of severe tricuspid regurgitation on functional status and long-term survival. Transcatheter therapies represent a promising alternative for patients with severe tricuspid regurgitation and high surgical risk...

The use of diagnostic medical imaging is becoming increasingly more commonplace in the pediatric setting. However, many medical imaging modalities expose pediatric patients to ionizing radiation, which has been shown to increase the risk of cancer development in later life. This review article provides a comprehensive overview of the available data regarding the risk of cancer development following exposure to ionizing radiation from diagnostic medical imaging. Attention is paid to modalities such as computed tomography scans and fluoroscopic procedures that can expose children to radiation doses orders of magnitude higher than standard diagnostic x-rays...

Wensen Feng, Peng Qiao, Yunjin Chen
The degradation of the acquired signal by Poisson noise is a common problem for various imaging applications, such as medical imaging, night vision, and microscopy. Up to now, many state-of-the-art Poisson denoising techniques mainly concentrate on achieving utmost performance, with little consideration for the computation efficiency. Therefore, in this paper we aim to propose an efficient Poisson denoising model with both high computational efficiency and recovery quality. To this end, we exploit the newly developed trainable nonlinear reaction diffusion (TNRD) model which has proven an extremely fast image restoration approach with performance surpassing recent state-of-the-arts...

AIMS: Surgical excision of all benign vascular lesions of the breast identified by core needle biopsy has been recommended in the past to rule out a more serious lesion. In this study we investigated the clinical, radiologic, and pathologic findings in patients diagnosed with a benign vascular lesion at our institution to assess whether excision may be spared for lesions without atypia. METHODS AND RESULTS: We searched the electronic medical record for patients with a vascular lesion of the breast diagnosed between 2000 and 2015...

BACKGROUND: The Los Angeles (LA) grade of reflux esophagitis (A to D) is assumed to reflect severity of the underlying gastroesophageal reflux disease (GERD). Thus, LA-D esophagitis patients might be expected to have the most conditions predisposing to GERD (eg, obesity, hiatal hernia), and the highest frequency of GERD symptoms. GOALS: The main goal of this study is to compare clinical features of patients with the most severe (LA-D) and mildest (LA-A) grades of esophagitis...

OBJECTIVE Smoking is a known risk factor for aneurysm development and aneurysmal subarachnoid hemorrhage, as well as subsequent vasospasm in both untreated individuals and patients who have undergone surgical clipping of cerebrovascular aneurysms. However, there is a lack of data in the current scientific literature about the long-term effects that smoking has on the integrity of endovascular repairs of cerebral aneurysms. This study was designed to determine if any smoking history increased the risk of poorer outcomes and/or aneurysm recurrence in patients who have had endovascular repair of cerebral aneurysms...

BACKGROUND: Noncompaction is a poorly understood form of cardiomyopathy that typically affects the left ventricle and may be associated with congenital heart disease. Right ventricular noncompaction (RVNC) may occur when the left ventricle is affected but is rarely seen in isolation. RVNC may have clinical significance affecting surgical and long-term outcomes. We describe the diagnosis and clinical course in three patients at our institution. METHODS: We performed a retrospective review of patients diagnosed with RVNC over a 12-month period at our institution and reviewed their imaging and clinical course...

The primary curative modality for localized rectal cancer is total mesorectal excision (TME). Local control rate of rectal cancer has been improved after neoadjuvant chemoradiotherapy and even pathological complete response (pCR) has been demonstrated in a significant minority. Patients who achieve pCR to neoadjuvant chemoradiotherapy have an excellent prognosis compared with those without pCR. If the patients with complete response to neoadjuvant chemoradiation can be demonstrated by clinical findings and medical imaging (cCR), a non-operative management (NOM) strategy may be pursued to preserve sphincter function and avoid complications induced by TME, which is a new tendency in the treatment of rectal cancer in recent years...
