The purpose of this study was to investigate the motor function of the esophagus in patients with chronic caustic esophagitis. We evaluated 7 patients between 2 and 10 years of age, who had ingested caustics between 15 months and 3 years of age. The method we used was radiology with fluoroscopy vision and manometry. There was no correlation between(More)
PURPOSE Familial amyloidosis with polyneuropathy (FAP) sometimes courses with vitreous amyloid. The aim of this study was to evaluate the incidence of glaucoma after vitrectomy in FAP patients. METHODS A total of 79 eyes of 42 liver transplanted FAP patients and 16 eyes of 16 non-FAP patients with rhegmatogenous retina detachment were collected. The(More)
—For conventional cyclic-prefix (CP)-assisted block transmission systems, the CP length is selected on the basis of the expected maximum delay spread. With regard to single-carrier (SC)-based block transmission implementations, a full-length CP is recommendable, since it allows good performances through the use of simple frequency-domain equalization (FDE)(More)
PURPOSE Vitreous amyloid deposits are one of the most common ocular manifestations of familial amyloidosis ATTR V30M (FAP-I), which can be the only manifestation of the disease and can appear even after liver transplantation. Removal by vitrectomy is usually performed, but vitreous amyloid recurrence has been frequently reported. This study was undertaken(More)
PURPOSE Assessment of ocular involvement in transthyretin-related familial amyloidosis with polyneuropathy (FAP) in a large cohort of Portuguese patients. METHODS We reviewed the medical records of 513 Portuguese FAP mutation carriers, at the Ophthalmology Service, Centro Hospitalar do Porto, between 1 January 2008 and 31 January 2013. Abnormal(More)
The usefulness of a new pediatric duodenoscope PJF in the diagnosis of neonatal cholestasis was studied in 23 infants with ages ranging from 19 to 150 days. In 22 of 23 infants the papilla was cannulated. In 13 of 14 neonates (93%) with neonatal hepatitis, the common bile duct was opacified and biliary atresia was excluded. In one of two neonates with(More)
This study assessed the usefulness of ERCP in the diagnosis of biliary atresia. We evaluated 57 infants with prolonged cholestasis with abdominal ultrasound, liver biopsy, and ERCP. Using clinical observations alone, 22 infants were thought to have biliary atresia; whereas 35 children were thought to have neonatal hepatitis. The ERCP was performed with a(More)

UNLABELLED PURPOSE. Evaluation of the use of topical cyclosporine eyedrops in the treatment of severe dry eye disease in liver transplanted patients with familial amyloidotic polyneuropathy (FAP) unresponsive to therapy with artificial tears and lacrimal plugs. METHODS A prospective clinical study of 5 patients (10 eyes) admitted to the Ophthalmology(More)
The aim of this study was to evaluate if Portuguese patients with familial amyloidosis, liver transplanted and not, have an earlier development of presbyopia compared with a normal population and its relation with the presence or the absence of anterior capsule opacification of the lens. This study was performed to evaluate if Portuguese patients with(More)
