Pott's puffy tumor, a feature of osteomyelitis of the frontal bone, is a rare entity, especially in adults. Sir Percival Pott originally described this condition as a complication of trauma to the frontal bone. This is also a recognized complication of fronto-ethmoidal sinusitis. We present a rare case of Pott's puffy tumor caused by an insect bite(More)
AIMS A study was undertaken to determine and compare the F-actin staining patterns in the cells of the lamina cribrosa (LC) of normal, dexamethasone (DEX)-treated and glaucomatous dissected tissue and cell cultures. METHODS About 30 dissected donor eyes and nine cell lines provided the human specimens; 25 eyes and 20 primary cell cultures provided the(More)
PURPOSE To report an isolated case of extraocular seeding of choroidal melanoma after a transretinal biopsy. METHODS A 74-year-old man with a choroidal melanoma in the left eye underwent a 3-port transconjunctival 25-gauge transretinal biopsy (for cytogenetic prognostication) followed by proton beam radiotherapy. Biopsy showed the melanoma to be(More)
Necrotising fasciitis (NF) is an extremely rare skin and soft tissue infection with extensive necrosis of the subcutaneous tissue and underlying fascia, which usually affects the limbs and trunk. It rarely affects the head and neck region because of the excellent blood supply in this region. We report a case of NF initially misdiagnosed as a traumatic(More)
In this year’s WMT translation task, Finnish-English was introduced as a language pair of competition for the first time. We present experiments examining several variations on a morphologically-aware statistical phrase-based machine translation system for translating Finnish into English. Our system variations attempt to mitigate the issue of rich(More)
The use of wireless sensor networks (WSN) in health-care has been rapidly increased in the last few years. Miniaturization of sensor nodes, in-body data communication, bio-compatibility are the main outcomes of the on-going extensive research on nano-technology, wireless communication and bio-medical engineering, respectively. Sensing of various(More)
Radiation retinopathy is a vision-threatening complication following therapeutic irradiation of ocular, orbital, facial, nasopharyngeal and cranial structures. It is characterised by a delayed onset, slowly progressive, occlusive retinal microangiopathy that develops several years after initial radiotherapy. We present the case of a 44-year-old man who(More)
Editor, A 73-year-old-woman was referred to the Liverpool Ocular Oncology Centre for treatment of a symptomatic choroidal melanoma in the right eye, the lesion being discovered when blurred vision occurred. The right fundus showed an inferotemporal choroidal melanoma extending to the fovea. On ultrasonography, the tumour measured approximately 15 · 14 mm(More)
In recent years, the use of wireless sensor networks for vibration monitoring is emphasized, because of its capability to continuously monitor at hard-to-reach locations of complex machines. Low power consumption is one of the main requirements for the sensor nodes in continuous and long-term vibration monitoring. However, the power consumption of(More)
