OBJECTIVE: to verify the effect of the addition of dicalcium phosphate dihydrate (DCPD) particles functionalized with di- or triethylene glycol dimethacrylate (DEGDMA or TEGDMA) on the degree of conversion (DC), post-gel shrinkage (PS), mechanical properties, and ion release of experimental composites. METHODS: Four composites were prepared containing a BisGMA/TEGDMA matrix and 60 vol% of fillers. The positive control contained only barium glass fillers, while in the other composites 15 vol% of the barium was replaced by DCPD...

Budd-Chiari syndrome (BCS) is a rare but life-threatening disease. If not treated promptly, it is almost always lethal of progressive liver failure, severe nutritional depletion, and renal failure at the late stage. We report the successful treatment of a 5-year-old boy with BCS due to a stenosis of the IVC with a 26-year follow-up. We performed percutaneous transluminal angioplasty (PTA), which resulted in a great improvement of BCS, and the disappearance of ascites. Restenosis occurred at 25 years after the initial angioplasty, for which balloon angioplasty was repeatedly performed...

BACKGROUND: Hydrocephalus is a multifactorial condition, whose aetiology is not fully understood. Congenital hydrocephalus frequently occurs in small and brachycephalic dog breeds. Although it is widely accepted that the cribriform plate located in the rostral cranial fossa (RCF) is a site of cerebrospinal fluid (CSF) drainage, the RCF has not been studied extensively. Literature reports indicate that a decreased caudal cranial fossa (CCF) volume in the course of the Chiari-like malformation may obstruct CSF circulation...

INTRODUCTION: In patients with a hypercoagulable state, such as patients with pulmonary embolism and/or Budd-Chiari syndrome, the complications from multiple gene mutations are more numerous than those from a single mutation. The authors present a woman with no major prior medical history who presented with pulmonary embolism and Budd-Chiari syndrome; this enigmatic co-occurrence has never been solely reported without underlying aetiology in a patient without prior medical conditions...

INTRODUCTION: Basilar invagination can result from a variety of systemic diseases that can weaken the structural integrity of the craniocervical junction. Definitive treatment often requires ventral decompression along with posterior decompression and fusion. Endonasal odontoidectomy is a relatively new minimal access procedure, however, quality of life after this procedure has not been reported. METHODS: We reviewed a consecutive database of endonasal odontoidectomy patients and identified those having posterior decompression and fusion...

Neurogenic bladder occur as a consequence of several conditions, most commonly posterior urethral valves syndrome, spina bifida, tethered cord, sacral agenesis, and Arnold-Chiari malformation. It is characterized by diminished bladder capacity and/or reduced compliance, associated with high-pressure voiding that can lead to deterioration of renal function if left untreated. When medical management fails, bladder reconstruction with bowel (aumentation ileocystoplasty) becomes the treatment of choice for these patients...

Chiari Malformation type I (CM-I) is a neurological disorder characterized by a displacement of the cerebellar tonsils through the foramen magnum into the spinal canal. Most research has focused on physical symptomatology but few studies include neuropsychological examinations. Moreover, although current research highlights the involvement of the cerebellum on higher cognitive functions, little is known about cognitive consequences associated with CM-I. The aim of this study is to analyze cognitive functioning between 39 CM-I patients and 39 healthy controls, matched by gender, age and years of education...

Background: Arnold Chiari malformation (ACM) is characterized by an anatomical defect at the base of the skull where the cerebellum and the spinal cord herniate through the foramen magnum into the cervical spinal canal. Among the subtypes of the condition, ACM type I (ACM-I) is particularly outstanding because of the severity of symptoms. This study aimed to analyze the orofacial clinical manifestations of patients with ACM-I, and discuss their demographic distribution and clinical features in light of the literature...

OBJECTIVE Fast magnetic resonance imaging (fsMRI) sequences are single-shot spin echo images with fast acquisition times that have replaced CT scans for many conditions. Introduced as a means of evaluating children with hydrocephalus and macrocephaly, these sequences reduce the need for anesthesia and can be more cost-effective, especially for children who require multiple surveillance scans. However, the role of fsMRI has yet to be investigated in evaluating the posterior fossa in patients with Chiari I abnormality (CM-I)...

BACKGROUND AND PURPOSE: Currently no quantitative objective test exists to determine disease severity in a patient with Chiari I malformation. Our aim was to correlate disease severity in symptomatic patients with Chiari I malformation with cough-associated changes in CSF flow as measured with real-time MR imaging. MATERIALS AND METHODS: Thirteen symptomatic patients with Chiari I malformation (tonsillar herniation of ≥5 mm) were prospectively studied. A real-time, flow-sensitized pencil-beam MR imaging scan was used to measure CSF stroke volume during rest and immediately following coughing and relaxation periods (total scan time, 90 seconds)...

Although epidermal growth factor receptor (EGFR) and v-Ki-ras2 Kirsten rat sarcoma viral oncogene (KRAS) mutations were thought to be mutually exclusive in patients with non-small cell lung cancer (NSCLC), the development of high sensitive large-scale mutation analysis, has increasingly shown that activating EGFR mutations occasionally coexist with other dominant genetic alterations. Herein, we discuss the case of a patient with advanced NSCLC harboring both the uncommon EGFR G719S and the KRAS G12C mutations, who was treated for 9 years with erlotinib achieving a long-term survival...

This study aimed to present long-term results of a 12-year patient follow-up of recoverable stents for BCS complicated by inferior vena cava (IVC) thrombosis. Forty consecutive patients with BCS complicated by IVC thrombosis were treated with recoverable stents. The median duration of symptoms was 24 months. Recoverable stents was placed after predilation of the obstructed IVC, and then agitation thrombolysis or catheter-directed thrombolysis of IVC was performed. The recoverable stents was removed eventually after thrombus disappeared...

Background: In patients with Chiari I malformation (CMI), the occurrence of acute neurologic deficit after craniocervical trauma is rare. However, the pathologic potential of exacerbating anatomic overcrowding of the posterior fossa has immense clinical consequences and prompt recognition is essential. Case Description: This case study describes a 41-year-old male who sustained a single blow to the face, fell, and struck the occiput. On admission, neurological examination revealed a profound paraparesis, upper extremity diplegia, a C4 sensory level and apnea that required intubation...

BACKGROUND: Traditional teaching is that Chiari 1 malformations with syrinx should be operated as soon as possible. We present 2 cases of a radiologically proven Chiari 1 malformation with syrinx which were treated nonoperatively and improved radiologically. METHODS: Two children with an MRI-proven Chiari 1 malformations were followed up nonoperatively for 7 years (2010-2017). One was a boy aged 8 years and the other a girl aged 9 years at first presentation. Their parents were not interested in a surgical option and so it was decided to adopt a wait-and-watch policy...
