Sex Difference of Radiation Response in Occupational and Accidental Exposure
Conclusion and Outlook This review summarizes the data from major human studies on the health risks of radiation exposure and shows that sex can potentially influence the prolonged response to radiation exposure (Figure 1 and Tables 1, 2). These data suggest that long-term radiosensitivity in females is higher than that in males who receive a comparable dose of radiation. Our analysis of the literature agrees with the conclusions of the recent report on the Biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences (NAS), United States (National Research Council, 2006). The B...

Perioperative considerations and anesthesia management in patients with obstructive sleep apnea undergoing ophthalmic surgery
Obstructive sleep apnea (OSA) is a disorder characterized by breathing cessation caused by obstruction of the upper airway during sleep. It is associated with multiorgan comorbidities such as obesity, hypertension, heart failure, arrhythmias, diabetes mellitus, and stroke. Patients with OSA have an increased prevalence of ophthalmic disorders such as cataract, glaucoma, central serous retinopathy (detachment of retina, macular hole), eyelid laxity, keratoconus, and nonarteritic anterior ischemic optic neuropathy; and some might require surgery.

STIR-Net: Deep Spatial-Temporal Image Restoration Net for Radiation Reduction in CT Perfusion
In this study, we finalize extensive experiments to appraise the image restoration performance at different levels of tube current and spatial and temporal resolution scales. The results demonstrate the capability of our STIR-Net to restore high-quality scans at as low as 11% of absorbed radiation dose of the current imaging protocol, yielding an average of 10% improvement for perfusion maps compared to the patch-based log likelihood method.

Yet Another Health Problem Linked to Air Pollution: Eye Disease
It’s no secret that air pollution isn’t good for your health. In particular, exposure to the byproducts of burning the fuel that powers most of our motor vehicles has been linked to higher risk of lung cancer, respiratory infections, stroke and heart disease, as well as an increased risk of death from these conditions. A new study now adds another worrisome pollution-related risk: eye disease. Dr. Suh-Hang Hank Juo, from the center for myopia and eye disease at China Medical University in Taiwan, and his colleagues documented for the first time in a large population that exposure to two common air pollutants&md...

An update on clinical, pathological, diagnostic, and therapeutic perspectives of childhood leukodystrophies.
Authors: Ashrafi MR, Amanat M, Garshasbi M, Kameli R, Nilipour Y, Heidari M, Rezaei Z, Tavasoli AR Abstract Introduction: Leukodystrophies constitute heterogenous group of rare heritable disorders primarily affecting the white matter of central nervous system. These conditions are often under-appreciated among physicians. The first clinical manifestations of leukodystrophies are often nonspecific and can occur in different ages from neonatal to late adulthood periods. The diagnosis is, therefore, challenging in most cases.Area covered: Herein, the authors discuss different aspects of leukodystrophies. The authors used...

A Multicenter Study of Multimorbidity in Older Adult Inpatients in China
ConclusionsMultimorbidity is common in older Chinese inpatients with a national prevalence of 69.3% that increases in line with age. Age, region, area, BMI, and daily activities were independent factors significantly associated with multimorbidity in older inpatients. Clinicians should therefore focus more attention on multimorbidity.

COL4A1 Mutation as a Cause of Familial Recurrent Intracerebral Hemorrhage
We report a family in which the index case presented with two intracerebral hemorrhages in the basal ganglia with severe periventricular leukoaraiosis and a cataract and vascular tortuosity in the ophthalmological study. His twin brother also had severe leukoaraiosis and multiple subcortical microhemorrhages as well as a congenital cataract and vascular tortuosity in the retina.

A change of heart: Transformation of the electrocardiogram in a patient with apical hypertrophic cardiomyopathy
An asymptomatic 83-year-old man with a history of hypertension, prior stroke with no residual deficits, and bilateral carotid artery stenosis, presented for evaluation prior to cataract surgery. His transthoracic echocardiogram was typical for apical hypertrophic cardiomyopathy (AHCM), and his electrocardiograms (ECG) showed large precordial R-waves and inverted T-waves, previously associated with AHCM, while his ECG 7  years earlier was normal. Mechanistic explanations for the developed ECG abnormalities, and their importance for the detection and monitoring of patients with AHCM are provided.

I am an eye surgeon but could soon be your doctor in the ICU. I'm terrified
I am fearful for the future, uncertain for how my skills will hold up when put to testCoronavirus – latest updatesSee all our coronavirus coverageI am an ophthalmologist. I am the doctor you see for your cataract surgery, the doctor your grandmother sees to have her age-related macular degeneration checked, the one who prescribed the bedtime drops to slow down your grandfather ’s glaucoma. In the next few weeks I will be the doctor your father sees for his stroke, the doctor who treats your grandmother’s heart failure, the doctor you see in A&E to treat your asthma. Potentially the doctor you meet in intensive ca...

Domestic energy usage and its' health implications on residents of the Ese ‐Odo and Okitipupa local government areas of Ondo state, Nigeria
This study examined domestic energy usage and its health implication on residents of Ese ‐Odo and Okitipupa Local Government Areas (LGA), of Ondo State. Systematic random sampling was used to select 103 and 156 respondents in Ese‐Odo and Okitipupa LGA, respectively. It was established that environmental and socio‐economic related attributes influenced residents' choice of domestic energy type. Similarly, burns, blindness, stroke, cataract and pulmonary diseases were the most prevalent self‐reported ill‐health. A relatively weak correlation between domestic energy usage and ill‐health is experienced by the resid...

Fetal brain small vessel disease 1 caused by a novel mutation in the COL4A1 gene
AbstractA singleton fetus was referred to fetal magnetic resonance imaging (MRI) at 25  weeks due to mild ventriculomegaly and an abnormal fetal echocardiogram showing cardiomegaly, right ventricular hypertrophy and tricuspid insufficiency. Patchy areas of ischemic infarction, extensive subacute and chronic hemorrhage not respecting vascular territories, encephaloclastic cysts and cl osed lip schizencephaly were identified. Cataract was detected postnatally. The anomalies were caused by a pathogenic mutation (c.353 G>A; p.G118D) in the COL4A1 gene. The phenotype seen in this case, i.e. small vessel cerebral disease wi...

How Good is Photoscreening For Young Children ’ s Vision Problems?
This study showed that not only was smartphone photoscreening feasible, but was quite good at screening for potential vision problems. Smartphone photoscreening has the advantages of being more ubiquitously available and thus children in almost any location can be screened. A study of photoscreening using a handheld digital photoscreener in primary care offices validated the technology showing an overall referral rate of 10% to an ophthalmologist with suspected astigmatism, anisometropia and strabismus being the most common reasons. The overall positive predictive rate was 0.60. “…[O]ver 60% of children referre...
