Oral physicians frequently encounter medically compromised patients in their everyday practice and a sizable number of these patients are in urgent need of specialized care. One such medically specialized category is that of patients suffering from hydrocephalus. A large number of medical reports and citations in support of surgical care of the hydrocephalic disorder are available in literature. However, reports on dental studies offer contradictory statements on the relationship between hydrocephalic shunts and oral manoeuvres...

OBJECTIVE: Obstructive hydrocephalus (HCP) related to vestibular schwannoma occurs in large tumors compressing the fourth ventricle. Symptoms related to HCP are expected to alleviate after resection of the tumor and decompression of the cerebrospinal fluid (CSF) pathways. However, some patients may require permanent cerebrospinal diversion even after surgery due to persistent HCP. In this study, the authors try to find out the factors associated with the requirement of CSF diversion after vestibular schwannoma surgery in cases of persistent HCP...

BACKGROUND: Acute failure of the Fontan circulation is rare but remains associated with high morbidity and mortality rates. Little is known about the long-term outcome of patients who underwent Fontan takedown to an intermediate palliative circulation and their potential candidacy for redo Fontan completion. METHODS: Patients followed up at a single institution who underwent takedown of a Fontan circulation to an intermediate palliative circulation within 2 months of extracardiac Fontan completion were reviewed...

Cynomolgus monkeys are often used in preclinical transplantation research. Performing liver transplantation in cynomolgus monkeys is challenging because they poorly tolerate portal vein clamping during the anhepatic phase. Finding an alternative to portal vein clamping is necessary before preclinical liver transplant models can be performed with reliable outcomes. We used 3 different techniques to perform 5 liver transplants in male cynomolgus macaques (weight, 7.4-10.8 kg; mismatched for MHC I and II; matched for ABO)...

INTRODUCTION: Headaches, visual problems and tinnitus are symptoms of Idiopathic Intracranial Hypertension (IIH) which resolve with reduction of CSF pressure. Impaired cranial venous outflow has been implicated in the pathogenesis and there is evidence of good treatment results in IIH using venous sinus stenting. We are currently initiating a multi-centre randomised controlled trial, the VISION study (Venous Intervention versus Shunting in IIH for Optic Disc Swelling) comparing radiological (venous sinus stenting) to surgical intervention (CSF shunting)...

BACKGROUND/AIMS: The management of extracerebral collections of fluid in patients with hydrocephalus can be problematic for either their simultaneous separate management or sequential management, each of which may require multiple surgeries and the management of external drains. The object of this report is to review the experience with a shunt configuration that simultaneously diverts ventricular fluid and extracerebral fluid, whether subdural or subarachnoid in location, through different outflow resistances...

A partial anomalous pulmonary venous connection (PAPVC) is a rare congenital defect in which at least one pulmonary vein doesn't drain into the left atrium but into a systemic vein or even into the right atrium, causing a left-to right shunt. PAPVC with a small amount of shunt are usually asymptomatic, and can not be detected during lifetime. Nevertheless, if those patients undergo a major lung resection, the surgical procedure could precipitate right heart failure if this anomalous shunt remains uncorrected...

BACKGROUND AND AIMS: Budd-Chiari syndrome (BCS) is treated with anticoagulation therapy, transjugular intrahepatic portosystemic shunt (TIPS), angioplasty, and liver transplantation. TIPS is not always technically feasible, due to the complete hepatic venous thrombosis. Direct intrahepatic portosystemic shunt (DIPS) is an alternative method for decompression of portal hypertension. This is a retrospective, single-center study aiming to evaluate the outcome of ultrasound (US)-guided DIPS in patients with BCS...

Glaucoma leads to blindness but there are diagnostic and therapeutic developments that aid ophthalmologists in the improved mangement of the disease compared to the past. Known risk factors such as age, myopia, dark pigmented skin, genetics, and elevated intraocular pressure play an important role for the individual patient's prognosis, and many yet unknown or not sufficiently investigated risk factors come along. The structured examination of the optic nerve head is crucial for the clincial diagnosis by the ophthalmologist...

External ventricular drains (EVD) are essential in the early management of hydrocephalus and elevated intracranial pressure after subarachnoid hemorrhage (SAH). Once in place, management of the EVD is thought to influence long-term patient outcomes, rates of ventriculitis, incidence of delayed cerebral ischemia, need for a ventriculoperitoneal shunt, and intensive care unit (ICU) and hospital length of stay. The available evidence supports adopting early clamp trials and intermittent cerebrospinal fluid (CSF) drainage...

We present a case of renal infarction in a 43-year-old female with history of stroke at age 14. She was found to be heterozygous for the prothrombin G20210A gene mutation. Loop monitoring revealed no atrial fibrillation. Transthoracic and transesophageal echocardiograms showed no thrombus. However, there was a small shunt due to an atrial septal defect (ASD). She was treated with warfarin and had device closure of her ASD. This was a suspected case of paradoxical embolism through an ASD leading to renal infarction...

Tubercular involvement of the thyroid gland is a rare entity. Tuberculosis of thyroid gland can present as cold abscess, multinodular goitre, acute abscess or generalized goitre. Clinically, these patients can be euthyroid, hypothyroid or hyperthyroid. Diagnosis is made by fine needle aspiration and demonstration of acid fast bacilli. Here, we report the case of a 46-year-old male who presented with disseminated extrapulmonary tuberculosis with obstructive hydrocephalus and cold abscess of the thyroid gland...

Perinatal mortality remains high among fetuses diagnosed with Ebstein's anomaly of the tricuspid valve. The subgroup of patients with pulmonary valve regurgitation is at particularly high risk. In the setting of pulmonary valve regurgitation, early constriction of the ductus arteriosus may be a novel perinatal management strategy to reduce systemic steal resulting from circular shunt physiology. We report the use of chronic antepartum maternal oxygen therapy for constriction of the fetal ductus arteriosus and modulation of fetal pulmonary vascular resistance in a late presentation of Ebstein's anomaly with severe tricuspid valve regurgitation, reversal of flow in the ductus arteriosus, and continuous pulmonary valve regurgitation...

The description of totally anomalous systemic venous connection is limited to case reports. In this review, we seek to clarify anatomic, physiologic, and hemodynamic aspects of this extremely rare anomaly. We also present findings of two patients in whom connection of all the systemic veins was anomalous. In the first patient, with usual atrial arrangement, all systemic veins, including the coronary sinus, were connected anomalously to the morphologically left atrium. Limited left-to-right shunt across an atrial septal defect provided the only source of blood flow to the lungs...
