The purpose of this study was to prove the hypothesis that caloric response in Ménière's disease (MD) is reduced by hydropic expansion of the vestibular labyrinth, not by vestibular hypofunction, by evaluating the correlation morphologically using an intravenous Gadolinium (IV-Gd) inner ear MRI. In study I, the prevalence of abnormal video Head Impulse Test (vHIT) results among the patients wit...

Background Hereditary spherocytosis is the most common form of inherited hemolytic anemia and is characterized by a structural defect in the RBC membrane. The disorder is commonly inherited in an autosomal dominant fashion and leads to a mild to moderate anemia. The autosomal recessive form of hereditary spherocytosis is rarely reported in association with fetal anemia and hydrops fetalis. Ca...

Jiro Hozawa, Shigeki Kamata, Takashi Ishida and Noriko Kimura (Hirosaki University) The labyrinths of guinea pigs sensitized by horseradish peroxidase (HRP) were investigated by electronmicroscopy after challenging this antigen through the foram. stylomastoideum. Horizontal nystagmus toward the contralateral side was observed about fifteen minutes after challenging. The animals sacrified in thi...

to AVB and myocarditis, respectively, resulting in a poor prognosis. We previously reported that fetal hydrops is associated with a poor prognosis in fetuses without CHD7 and we suggested that myocardial dysfunction, rather than the severity of bradyarrhythmia, was associated with fetal hydrops. In contrast, in fetuses with CHD, congenital bradyarrhythmia is thought to result from the structura...

PURPOSE To report a case of acute hydrops in pellucid marginal corneal degeneration (PMCD) documented with anterior segment optical segment tomography and successfully treated with sulphur hexafluoride (SF6) intracameral injection. METHODS A 47-year-old female patient presented with spontaneous onset of pain, redness and decreased vision in her left eye. Clinical evaluation revealed bilateral...

The objective of this study was to determine endothelin (ET-1) concentrations in monochorionic twin fetuses with and without twin-twin transfusion syndrome (TTTS). Fourteen monochorionic twin pregnancies complicated by TTTS and six without TTTS were studied. Matched maternal and fetal blood samples were obtained both in utero and at birth. Amniotic fluid samples were also collected from twin pa...

Cases of Rhesus incompatibility resulting in the condition known as hydrops foetalis do badly. Mollison and Cutbush (1954) state 'it is doubtful if infants born with ascites ever survive', and it is difficult to find any record of survival. Heilig, Tudor, Smith and Platou (1948) report two cases of hydrops, one of which survived with a hemiplegia. Van Loghem, van Bolhuis, Soeters and Veeneklaas...

The authors describe the anterior segment optical coherence tomography (AS-OCT) findings of a 25-year-old patient with acute hydrops associated with keratoconus. The patient presented with decreased visual acuity, pain, and redness in the left eye. The symptoms, clinical presentation, and topographical findings of the right eye confirmed this condition to be acute corneal hydrops. The patient w...

Endocardial fibroelastosis, defined as an endocardium in excess of 30 microns thick, was found in 10 out of 34 cases of hydrops fetalis in a review of 1589 perinatal necropsies carried out between 1976 and 1989. The infants comprised 16 cases of rhesus haemolytic disease, of whom three had endocardial fibroelastosis, and 18 cases of non-rhesus hydrops, of whom seven had endocardial fibroelastos...

Electrocochleography (ECochG) has been used to assess Ménière's disease, a pathology associated with endolymphatic hydrops and low-frequency sensorineural hearing loss. However, the current ECochG techniques are limited for use at high-frequencies only (≥1 kHz) and cannot be used to assess and understand the low-frequency sensorineural hearing loss in ears with Ménière's disease. In the current...
