Neonatal Ventricular Reservoir Implantation for Hydrocephalus Management in Chiari III Malformations: A Case Report.

Chiari III malformation, a rare and severe subtype of Chiari malformations, is frequently associated with hydrocephalus. The conventional treatment approaches for hydrocephalus in Chiari III malformations have mainly focused on ventriculoperitoneal (VP) shunting, but optimal methods and timing remain uncertain. We report a case of a newborn girl with Chiari III malformation who underwent surgical closure of an occipitocervical encephalocele and ventricular reservoir implantation on her third day of life.

Efficacy and safety of the endoscopic "wet-field" technique for removal of supratentorial cavernous malformations.

Objective: Cerebral cavernous malformations (CMs) presenting with focal neurological symptoms or mass effects require surgical removal. In recent years, cylindrical retractors have been widely utilized for the removal of deep-seated lesions during both microscopic and endoscopic surgery. In the present study, we evaluated the efficacy and safety of endoscopic transcylinder removal of CMs using a novel wet-field technique.

Case of a Pregnant Woman with Capillary Hemangioma of the Parasellar Region.

Here we report a rare case of capillary hemangioma (CH) in a 28-year-old woman suffering from gradual worsening diplopia at 28 weeks of pregnancy. Magnetic resonance imaging (MRI) showed a mass lesion (about 3 cm in diameter) in the right parasellar region. We decided to observe as she was pregnant, and had no symptoms other than right abducent nerve palsy.

Carotid Endarterectomy Requiring Removal of the Superior Horn of Thyroid Cartilage: Case Report and Literature Review.

Carotid endarterectomy (CEA) is an established surgical procedure for carotid stenosis. We present the case of a 74-year-old man who underwent CEA for symptomatic internal carotid artery (ICA) stenosis. During the operation, we found that the hyoid bone (HB) and the superior horn of the thyroid cartilage covered the carotid sheath, preventing adequate visualization.

Oxidative stress and antioxidative potency are closely associated with diabetic retinopathy and nephropathy in patients with type 2 diabetes.

Objective: To examine involvement of oxidative stress in the pathogenesis and vascular complications of diabetes.

Methods: This cross sectional study was conducted at the Joint Laboratory Office (JLO), Dokkyo Medical University Koshigaya Hospital, Koshigaya, Japan from April 2010 to December 2011. Fasting glucose, glycosylated hemoglobin (HbA1c), serum lipids, urinary albumin excretion (UAE), ankle brachial index and pulse wave velocity were measured in 51 patients with type 2 diabetes and 20 healthy controls.

A subtype-specific critical period for neurogenesis in the postnatal development of mouse olfactory glomeruli.

Sensory input is essential for the normal development of sensory centers in the brain, such as the somatosensory, visual, auditory, and olfactory systems. Visual deprivation during a specific developmental stage, called the critical period, results in severe and irreversible functional impairments in the primary visual cortex. Olfactory deprivation in the early postnatal period also causes significant developmental defects in the olfactory bulb, the primary center for olfaction.
