Letter to the Editor: Pneumocephalus: Is the needle size significant?
Discussion. Pneumocephalus is defined by two mechanisms: a ball-valve and an inverted bottle concept.1 The ball-valve type implies positive pressure events, such as coughing or valsalva maneuvers, that prevent air escape. Tension pneumocephalus is included in this mechanism, causing a parenchymal mass effect. The inverted bottle theory includes a negative intracranial pressure gradient following cerebrospinal fluid drainage, relieved by air influx. A small pneumocephalus is usually sealed by blood clots or granulation, allowing spontaneous reabsorption and resolution.[1] Otherwise, the lateral positioning of a patient duri...

Cerebellar Hematoma Location Brief Report
Background and Purpose—Spontaneous cerebellar intracerebral hemorrhage (ICH) has been reported to be mainly associated with vascular changes secondary to hypertension. However, a subgroup of cerebellar ICH seems related to vascular amyloid deposition (cerebral amyloid angiopathy). We sought to determine whether location of hematoma in the cerebellum (deep and superficial regions) was suggestive of a particular hemorrhage-prone small-vessel disease pathology (cerebral amyloid angiopathy or hypertensive vasculopathy).Methods—Consecutive patients with cerebellar ICH from a single tertiary care medical center were recruite...

A study of clinical, radiological and etiological profile of cerebral venous sinus thrombosis at a tertiary care center
Conclusion CVST is an important yet under recognized cause of intracranial hypertension and stroke in young. Clinical presentation is extremely varied and a high index of suspicion is needed. Magnetic Resonance Imaging (MRI) brain with Magnetic Resonance Venography (MRV) is the current diagnostic modality of choice. Elevated factor VIII and puerperium are the common etiologies in an Indian population. Management with anticoagulants is safe and has excellent clinical outcomes.

Long-term pulmonary and cardiovascular morbidities of neonatal hyperoxia exposure in mice.
Abstract Pulmonary hypertension (PH) frequently occurs in infants with bronchopulmonary dysplasia (BPD), causing increased mortality and right ventricular (RV) dysfunction that persists into adulthood. A first step in developing better therapeutic options is identifying and characterizing an appropriate animal model. Previously, we characterized the short-term morbidities of a model in which C57BL/6J wild-type (WT) mice were exposed to 70% O2 (hyperoxia) during the neonatal period. Here, we aimed to determine the long-term morbidities using lung morphometry, echocardiography (Echo), and cardiac magnetic resonance ...

Doctors develop new way to use MRI to predict pregnancy complications
FINDINGSUCLA scientists have developed anew way to use magnetic resonance imaging, or MRI, to scan the placenta. The noninvasive approach offers valuable insights into how the mother ’s blood enters the placenta and sustains the fetus with oxygen and nutrients during early pregnancy. The technique breaks new ground because most previous studies on this subject occurred in the laboratory after childbirth.BACKGROUNDThe placenta is a temporary organ that joins a pregnant woman to her baby through the umbilical cord. Few methods exist for safely and accurately studying the placenta in early pregnancy. Ultrasound indirectly m...

Aldosterone Target NGAL (Neutrophil Gelatinase-Associated Lipocalin) Is Involved in Cardiac Remodeling After Myocardial Infarction Through NF{kappa}B PathwayNovelty and Significance Heart
In conclusion, NGAL, a downstream MR activation target, is a key mediator of post-MI cardiac damage. NGAL may be a potential therapeutic target in cardiovascular pathological situations in which MR is involved.

Lateral medullary infarction with similar features of Brown Sequard syndrome caused by vertebrobasilar dysplasia and Klippel–Feil syndrome: A case report
Rationale: Patients with Klippel–Feil syndrome (KFS) are always anomaly associated with vertebrobasilar dysplasia. That may present commonly as infarction of brainstem, medulla, and cerebellum. In this article, we reported a rare case of lateral medullary infarction (LMI) with similar features of Brown Sequard syndrome caused by vertebrobasilar dysplasia and KFS, and the 2 rare conditions that are causally related. The case is being reported because of its unusual and rare presentation. Patient concerns: A 38-year-old female presented with acute unsteadiness, along with a tendency to lean to the left side while walk...

A Case of ALL Developing Posterior Reversible Encephalopathy Secondary to Hyponatremia
We describe a case of acute lymphoblastic leukemia in which PRES developed secondary to hyponatremia despite being normotensive during receipt of chemotherapy. Magnetic resonance imaging findings were suggestive of PRES. Partial diffusion restriction was observed in lesions in the bilateral occipitoparietal regions and the cerebellum. The patient was treated with appropriate medications with the resolution of his stroke-like symptoms. No neurological deficit was observed and clinical condition improved. The patient continued with chemotherapy. Early diagnosis and treatment of this syndrome is important in terms of preventi...

Age, vascular health, and Alzheimer disease biomarkers in an elderly sample
ObjectiveTo investigate the associations between age, vascular health, and Alzheimer disease (AD) imaging biomarkers in an elderly sample. MethodsWe identified 430 individuals along the cognitive continuum aged >60 years with amyloid positron emission tomography (PET), tau PET, and magnetic resonance imaging (MRI) scans from the population‐based Mayo Clinic Study of Aging. A subset of 329 individuals had fluorodeoxyglucose (FDG) PET. We ascertained presently existing cardiovascular and metabolic conditions (CMC) from health care records and used the summation of presence/absence of hypertension, hyperlipidemia, cardia...

Stroke in a Young Man Secondary to Paroxysmal Atrial Fibrillation and Thyrotoxicosis: A Case Report
We report a case of a male patient with stroke caused by atrial fibrillation (AF) due to thyrotoxicosis. At hospital admission, he presented hypertension and AF. Magnetic resonance imaging confirmed a right-side ischemic area. The thyrotoxicosis was confirmed by thyroid function and thyroid scintigraphy that showed goiter with diffuse hypercaptation. The patient was treated with tapazole and total thyroidectomy, and pathological findings suggested Graves ’ disease. Hyperthyroidism is associated with increased supraventricular ectopic activity in patients with a normal heart, and may be an important causal link between hy...
