BACKGROUND AND PURPOSE The brain stem in patients with periventricular leukomalacia (PVL) appears smaller than normal on MR imaging, but few reports have described this feature, and the number of patients has been relatively small. The present study was conducted to examine the hypothesis that the pons in patients with PVL is smaller than normal. MATERIALS AND METHODS Using MR imaging, we exa...

OBJECTIVE We aimed to in-vitro test Amplatzer devices (Amplatzer Vascular Plug II and Amplatzer Vascular Plug III, SJM, St. Paul, MN) in closing PVL generated by transcatheter balloon expandable aortic valve prosthesis in order to quantify the effective treatment of PVL. BACKGROUND Transcatheter aortic valve implantation (TAVI) procedures represent the treatment of choice for high risk patien...

Periventricular leukomalacia (PVL), the major substrate of cerebral palsy in survivors of prematurity, is defined as focal periventricular necrosis and diffuse gliosis in immature cerebral white matter. We propose that nitrosative and/or oxidative stress to premyelinating oligodendrocytes complicating cerebral ischemia in the sick premature infant is a key mechanism of injury interfering with m...

It has been shown previously that high rates of methicillin- and mupirocin-resistant Staphylococcus aureus exist in the Caribbean islands of Trinidad and Tobago, as well as a high prevalence of Panton-Valentine leukocidin-positive S. aureus. Beyond these studies, limited typing data have been published. In order to obtain insight into the population structure not only of MRSA but also of methic...

During an 18 month period, 120 preterm infants of 34 weeks' gestation or less were prospectively examined for periventricular leucomalacia (PVL) by cerebral ultrasound. Neurological and developmental assessment was carried out at 18 months of age corrected for prematurity in 82 surviving neonates. The developmental outcome (Griffiths development quotient) was above 80 and similar in infants wit...

Proliferative verrucous leukoplakia (PVL) is an uncommon entity with a high tendency to develop oral squamous cell carcinomas (OSCCs). The objective of this study was to analyse the presence of various OSCCs in the same patient with PVL. We studied 19 patients with PVL who had developed at least one OSCC. We analysed how many of these developed more than one OSCC over a period between 24 and a ...

conclusions community acquired (ca)-mrsa is becoming a public health concern in many parts of the world, including asian countries. the variable prevalence of luk-pv-positive mrsa isolates in different regions and their rather high frequency in pneumonia necessitate the application of rapid diagnostic methods such as real-time pcr to improve treatment effectiveness. materials and methods in tot...

Biodegradable poly(ethyleneglycol)-poly(valerolactone)-poly(ethyleneglycol) [PEG-PVL-PEG] copolymers were synthesized through ring opening polymerization of δ-valerolactone (VL) followed by the coupling of monomethoxy poly(ethyleneglycol-poly(valerolactone) (mPEG-PVL) with hexamethylene diisocyanate (HDI). The copolymers were characterized by (1)H NMR, FT-IR, and GPC. Block copolymers of PEG an...

ABSTRACT Perception and understanding of dispositions and intentions of others through their actions are of immense importance for adaptive daily-life behavior and social communication. Here we ask whether, and, if so, how this ability is impaired in adolescents who were born premature and suffer early periventricular damage, periventricular leukomalacia (PVL) that affects brain connectivity. T...

Background: Staphylococcus aureus is an opportunistic pathogen that colonizes and causes infections in humans. Panton Valentine Leukocidin (PVL) a cytolytic toxin produced by some strains of S. are mostly associated with skin soft tissue necrotizing pneumonia. Aim: To investigate the prevalence genotypic characteristics PVL-positive cultured from patients three tertiary hospitals Jos, Nigeria. ...
