By reducing energy density, low-energy sweeteners (LES) might be expected to reduce energy intake (EI) and body weight (BW). To assess the totality of the evidence testing the null hypothesis that LES exposure (versus sugars or unsweetened alternatives) has no effect on EI or BW, we conducted a systematic review of relevant studies in animals and humans(More)
Microvessels were counted in 41 primary oral squamous cell carcinomas using JC70 antibody to PECAM (CD31). The counts were compared with clinical and pathological indicators of tumour behaviour including lymph node status, tumour stage, type of histological differentiation, size and velocity of tumour growth. Tumour microvessel counts correlated with lymph(More)
Sessile (villous) tumours of the rectum are uncommon and individual surgeons are unlikely to have wide experience in their management. A study was made of a unique personal series (AMC) of 104 cases encountered from 1974 to 1984; minimum duration of follow-up was 5 years. Clinically obvious rectal cancers were excluded from the study. Ages ranged from 42 to(More)
Over an 8-year period prospective series of 213 consecutive patients with venous ulceration of 232 limbs has been studied. By means of clinical, hand-held Doppler ultrasound and comprehensive ascending and descending venography examination, it was possible to identify underlying morphological abnormalities and on the basis of these to divide patients into(More)
This study assessed the clinical outcome after insertion of a percutaneous endoscopic gastrostomy tube (PEGT) by a maxillofacial team in a series of 54 patients. The indication for PEG feeding was any patient with oropharyngeal cancer who was unlikely to return to oral feeding within 14 days. Fifty-two patients (96%) had tubes successfully inserted at the(More)
The nature and aetiology of orbital roof fractures is discussed and a strategy for their successful management outlined with reference to five clinical cases. Early recognition and treatment of these fractures reduces the high incidence of intra-cranial and ocular complications and the importance of a combined approach involving maxillofacial surgeons,(More)
We describe a 36-year-old patient with a stage III carcinoma (pT2N1M0) of the tongue that presented in the second trimester of pregnancy. It was treated by primary excision and reconstruction with a free flap. To our knowledge this is the first reported case of successful microvascular free tissue transfer for oral cancer during pregnancy.
Three patients who presented with giant cell lesions complicating ossifying fibroma, Paget's disease, and cherubism are reported. The giant cell lesions complicating ossifying fibroma and cherubism were diagnosed as giant cell granuloma (GCG), whereas the lesion complicating Paget's disease demonstrated more aggressive clinical and histologic features. The(More)
