Laparoscopic techniques are now commonly used for the repair of inguinal hernias, since they offer rapid postoperative recovery and low complication rates. These methods usually involve the use of sutures, staples or titanium spiral tackers for safe, secure mesh fixation. We report a rare case of obstruction and perforation of the small bowel resulting from(More)
The burden of Parkinson’s disease (PD) is likely to increase in the years to come as many countries, particularly those in Asia, face an ageing population. As such, it has been estimated that the number of individuals suffering PD in the world will double by the year 2030. There have been many descriptive epidemiological studies conducted to understand the(More)
We study the problem of broadcasting a Gaussian source over a Gaussian broadcast channel to two users with individual source-channel bandwidth mismatches, under a quadratic distortion measure. Specifically we study the tradeoff between the achievable distortion pairs between the two users. The case when the bandwidth-expansion factors of the two users are(More)
We study the problem of broadcasting a binary source over a two-receiver erasure broadcast channel with source-channel bandwidth mismatch under a Hamming distortion measure. Given the distortion constraints of both users, we establish a lower bound for the minimum latency required and show that this bound is at least as tight as the one obtained from the(More)
BACKGROUND Serious complications of laparoscopic fundoplication (LF) have been reported by surgeons new to LF. We investigated whether the reported benefits of LF could be realised by an established consultant, new to LF, without compromising safety, control of reflux or dysphagia rates obtained after open surgery. PATIENTS AND METHODS Outcome of 65(More)
We study a lossy source-broadcasting problem involving the transmission of a binary source over a two-receiver erasure broadcast channel. The motivation of our work stems from the problem faced by a server that wishes to singly broadcast content to a diverse set of users with fractional source reconstruction requirements. In this problem, the server wishes(More)
Motivated by error correction coding in multimedia applications, we study the problem of broadcasting a single common source to multiple receivers over heterogeneous erasure channels. Each receiver is required to partially reconstruct the source sequence by decoding a certain fraction of the source symbols. We propose a coding scheme that requires only(More)
Carotid endarterectomy has been established by two large randomised controlled trials (European Carotid Surgery Trial (ECST) and North American Symptomatic Carotid Endarterectomy Trial (NASCET)) as an important surgical procedure for the prevention of ischaemic strokes in patients presenting with transient cerebral ischaemia or non-disabling strokes(More)
The ventilatory function of 634 workers in small scale metal working industries was evaluated. Almost five percent (4.7%) of the workers were found to have FEV1.0/FVC ratio of less than 75%. Compared with the lung function of industrial workers reported by Zee, 10.9% were found to have low ventilatory function. Comparison of the ventilatory function(More)
We present a case of a 71-year-old male Chamorro patient from Guam who presented with progressive supranuclear palsy (PSP)-Richardson's syndrome. Considering his strong family history of parkinsonism and a PSP phenotype, he was clinically diagnosed with Guam parkinsonism-dementia complex (PDC). Magnetic resonance imaging (MRI) of the brain revealed(More)
