OBJECTIVE To study the presence of respiratory syncytial virus (RSV) and adenovirus in the effusions of the middle ear and adenoid tissue from patients with chronic otitis media with effusion by use of the polymerase chain reaction. METHOD The effusions and adenoid samples were collected from 32 children undergoing myringotomy and ventilation tube(More)
Herpes simplex Virus type 1 (HSV-1) was inoculated into 48 rabbits by 3 different routes: 10 rabbits were dosed by mouth, 18 rabbits injected in the tongue and 14 injected in the perineurium of the facial nerve at its entrance into the stylomastoid foramen. Some of the animals were killed after a week and others after three weeks. Facial palsy was produced(More)
Recent studies suggested herpes simplex virus type 1 as a major etiologic factor in Bell's palsy. To analyze different aspects of facial nene infections, Swiss mice were inoculated with HSV-l in tongue (41 animals) and auricle (44). Nineteen mice developed unequivocal signs of nevous infection, but only in 1 mouse was evident a facial palsy. Mice were(More)
A study was performed to evaluate nested PCR (nPCR) versus viral cultures as method and tear film versus corneal scrapings as specimen in the diagnosis of viral keratoconjunctivitis. Tear film specimens were taken from both eyes and corneal scrapings from the affected eye only in 17 patients with suspected viral keratoconjunctivitis. In 15 of the 17(More)
Background/Aim: Oral ganciclovir effectively prevents CMV disease, but late-onset CMV disease is increasingly observed in pancreas-kidney and bone-marrow transplants recipients, specially with long-term prophylaxis. Then, the aim of this study was to verify if prolonged administration of oral ganciclovir prophylaxis could induce late CMV recurrence or(More)
Polymerase chain reaction (PCR) has provided new insights in molecular biology. Recently, some studies have been focused on temporal bone pathology, with amplification of DNA from fixed sections of celloidin-embedded bones. The purpose of our study was to elucidate the utility of PCR in detection of minor concentrations of DNA from nonoptimal stored(More)
Viral respiratory tract infections cause a substantial amount of illness and death in children worldwide. The so-called respiratory viruses that include respiratory syncytial virus (RSV), influenza virus A (IA) and influenza virus B (IB), human parainfluenza viruses (PIV), adenovirus, coronavirus, rhinovirus, the recently discovered human metapneumovirus(More)
Objective: To study the efficacy of intrathecal ethanol block to relieve intractable spasticity in AIDS-related progressive multifocal leukoencephalopathy (PML) when long-term intrathecal baclofen infusion cannot be used.Methods: A 33-year-old man with AIDS-related PML developed very severe spastic paraparesis (Ashworth rigidity score, 4) and painful muscle(More)
Herpes simplex type 1 (HSV-1) has been implicated as a cause of facial paralysis. We developed an experimental model in rabbits in which we injected HSV-1 into the tongue. The animals were killed after one and three weeks. The geniculate and trigeminal ganglia and medulla were extracted and the samples were processed. The polymerase chain reaction (PCR),(More)
