Endolymph magnetic resonance imaging: Contribution of saccule and utricle analysis in the management of patients with sensorineural ear disorders

Endolymphatic hydrops features excess endolymph in the membranous labyrinth, and is a marker of Menière's disease. Between the early 1980s and late 2000s, MRI in Menière's disease aimed purely to rule out tumor or malformation as differential diagnoses for the pressure disorder. Progress in high-resolution MRI, however, now enables excess endolymph to be visualized in the membranous labyrinth, differentiating saccule and utricle in Menière's disease and in other clinical presentations such as cochleovestibular schwannoma. More recently, non-visibility of the saccule was demonstrated in a subgroup of Menière's disease patients, and utricle atelectasis in case of uni- or bilateral vestibular areflexia. Endolymph quantification remains highly controversial in terms of grading approach, but a simple semiology based on excess or deficient visualization of endolymph according to the compartment sheds light on the pathophysiological mechanisms of cochleovestibular disorder and may in future allow effective monitoring of medical and surgical treatment.     

核桃仁泥外敷治疗肌肉注射后皮下硬结的疗效观察

采用核桃仁泥外敷治疗１３８例（实验组）肌肉注射后皮下硬结，并与４０例（对照组）采用新鲜土豆片外敷硬结法比较。结果表明：实验组患者治疗１５天后Ⅰ度和Ⅱ度硬结治愈率分别为８１．１３％和４２．２５％，总有效率达９２．０３％，明显优于对照组（Ｐ＜０．００１）。     

The “Biplanar” forehead lift

A new technique of forehead rhytidectomy is presented that combines the best features of the coronal incision with those of the anterior hairline incision. The plane of dissection is formed by an anterior subcutaneous plane dissecting a lateral subgaleal plane. This approach is particularly valuable in patients with high foreheads, severe static wrinkling, and asymmetrical eyebrows.Presented in part at the Annual Meeting of the American Society of Aesthetic Plastic Surgeons, Boston, MA, 1984     

Hydrops Fetalis Caused by Fetal Kasabach-Merritt Syndrome

There have been only 2 previous reports of nonimmunologic hydrops fetalis (NIHF) caused by fetal Kasabach-Merritt syndrome, both of which were pathological studies. This is the first clinical case report of NIHF due to fetal Kasabach-Merritt syndrome that was prenatally diagnosed by sonography, computerized tomography, and percutaneous umbilical blood sampling.     

Endolymphatic sac surgery: analysis of 100 operations*

One hundred endolymphatic mastoid shunt operations in 89 patients with classical Menière's disease were analysed. The disease was bilateral in 18 patients (20%). The patients were carefully pre-selected by a comprehensive protocol of audiovestibular and metabolic investigations. All patients had definite electrophysiological evidence of endolymphatic hydrops with an enhanced negative summating potential on transtympanic electrocochleography. The surgical results were analysed both by the original American Academy of Ophthalmology and Otolaryngology Guidelines (AAOO, 1972) and the more recent modifications of the American Academy of Otolaryngology, Head and Neck Surgery (AA-HNS, 1985). Control of the vertigo was achieved in 81% of the patients overall, in 88% of the patients with unilateral disease and in 63% of the patients with bilateral disease. A significant hearing improvement was obtained in 19% of patients, no change in 55% and hearing became worse in 26%. Tinnitus improved in 38% of patients, was unchanged in 52% and became worse in 10%. Disability was assessed and there was no disability in 44% of the patients post-operatively, some degree of disability in 48% but only 8% were severely disabled and unable to sustain gainful employment.     

ACARDIAC TWIN FETUS WITH SEVERE HYDROPS FETALIS AND BILATERAL TALIPES VARUS DEFORMITY

Twin reversed-arterial-perfusion syndrome (TRAPS) is a rare complication of monochorionic twin pregnancies. TRAPS is characterized by the hemodynamic dependence of a “recipient” twin from a “pump” twin. The “recipient” twin exhibits lethal abnormalities, such as acardia and acephaly. Circulatory failure of the normal twin derives from the existence of arterio-arterial and veno-venous anastomoses within the placenta that allow retrograde perfusion of the acardiac twin by blood coming from the normal twin. Acardiac twinning is the most extreme manifestation of the twin-twin transfusion syndrome. This occurs in 1 in 100 monozygotic twin pregnancies and 1 in 35,000 births. We report a case of diamnionic monochorionic female twins in which the acardiac twin demonstrated severe hydrops fetalis and bilateral talipes varus deformity. Cesarean section was performed on a 27-year-old hypertensive gravida 2, para 1 mother for fetal indications at 32 6/7 weeks gestation. The acardiac fetus had a two-vessel umbilical cord measuring 43.5 cm in length and 0.8 cm in diameter. The proximal end inserted into the root of the normal twin's umbilical cord in an acute angle forming a “v” close to the placental disc. Structures rostral to the thorax were absent except for a round mass of flesh with three small buds in place of the head and neck, and bilateral upper extremities. Only the kidneys, right adrenal, small and large intestine, and rudimentary urinary bladder were present. Both feet demonstrated talipes varus deformity. The fetus was severely hydropic. The subcutaneous fat measured 4.5 cm in maximum thickness. The normal twin had a protracted course complicated with respiratory distress syndrome, moderate secundum atrial septal defect with left to right shunt, and thrombocytopenia of prematurity. The baby was eventually discharged after approximately 1 month. At the time of this report, 5 months postpartum, the neonate is growing and developing normally. To our knowledge, this is the first report of severe hydrops fetalis and talipes varus deformity in an acardiac twin.     

Mucopolysaccharidosis VII as cause of fetal hydrops in early pregnancy

We report on fetal hydrops presenting at 18 weeks of gestation and diagnosed as β-glucuronidase deficiency. The parents were first cousins and there were 2 previous similar fetal deaths. β-Glucuronidase was absent in cultured fetal fibroblasts and lymphoblasts but was normal in the tested relatives. The activities of other lysosomal enzymes were normal. © 1992 Wiley-Liss, Inc.
