Retinal diseases are the main causes of blindness in the Western world. Diabetic retinopathy and age-related macular degeneration continue to increase in prevalence and as main causes of vision loss. Intravitreal anti-VEGF and steroid injections have raised new expectations for their successful treatment. These agents act by stabilizing the blood-retinal barrier (BRB). Our group defined the BRB...

An incidental dural tear resulting in cerebrospinal fluid (CSF) leakage is a complication of spinal surgery, with a reported incidence of between 0.3% and 16% (1, 2). The patient is likely to experience symptoms of CSF hypovolemia, including postural headache plus nausea, vomiting, pain or tightness in the neck or back, dizziness, diplopia, photophobia, tinnitus, and/or blurred vision. The usua...

INTRODUCTION This study was designed to quantitatively evaluate the sealing effect of a polyvinyl chloride tapered endotracheal tube cuff and to compare the tapered cuff with cylindrical endotracheal tube cuffs using an in vitro viscous fluid model. METHODS Five types of 8.0 mm inner diameter endotracheal tubes (TaperGuard, PortexSacett, PortexSoftseal, Sheridan HVT, Sheridan CF) were fixed i...

BACKGROUND Spontaneous intracranial hypotension (SIH) has become a well-recognized syndrome. However, diagnosis of SIH is still challenging. The problem with SIH is that the precise mechanism of cerebrospinal fluid (CSF) leakage remains largely unknown and there is no definite diagnostic criterion in the imaging. METHODS The clinical findings of our ten cases and 301 literature reports on SIH...

Fault detection and isolation (FDI) is a useful tool to investigate proper performance of dynamic systems. With respect to hydraulic actuators, as they are extensively used in industry, and are responsible for producing accurate displacements and high forces, FDI role is crucial. One of the phenomena that can affect the internal leakage detection is the variation in the value of fluid effective...

Vulvar lymphatic leakage is a severe complication associated with gynecological cancer treatments. However, standard treatment strategies have not yet been determined. We encountered a rare case of a 76-year-old multiparous woman suffering from massive lymphatic fluid leakage from the entire vulva, and papules developed and were identified as lymphangiomas. A large amount of straw-colored disch...

OBJECTIVES To investigate apical leakage of roots filled with 6 different gutta-percha techniques; Thermafil, JS Quick-Fill, Soft Core, Microseal, System B and lateral condensation using a new computerized filtration meter. MATERIALS AND METHODS 60 extracted single rooted teeth were used. Coronal part of each tooth was removed and the root canals were prepared with step-back technique. The ro...

INRODUCTION The treatments of excluded bile duct leakage after hepatectomy are not easy and various strategies have been reported, such as surgery, ethanol or fibrin glue injection, and portal vein embolization. PRESENTATION OF CASE A 72-year-old man with a surgical history of laparoscopic ileocecal resection for diverticular bleeding was diagnosed as having hepatocellular carcinoma. Right he...

BACKGROUND Vertebral compression fracture is one of the frequent complications of osteoporosis. Percutaneous vertebroplasty (PVP) has been applied in the treatment of osteoporotic vertebral compression fractures, multiple myelomas and vertebral metastatic lesions. Complications of the procedure include bleeding at the puncture site, local infection, cement leakage in the vertebral canal and int...
