Extracellular pH (pHc) was determined by needle microelectrodes in 67 tumour nodules in 58 patients. The objective was to evaluate the relationship between pHe, tumour histology and tumour volume. The mean age of the patients was 62 years, mean depth of the lesions was 2.7 +/- 0.2 cm, and mean tumour volume was 187 +/- 60 cm3. Lesions were located in(More)
PURPOSE To review the methods and results of management in a large series of patients with Coats disease, to determine risk factors for poor visual outcome and enucleation, and to propose a practical classification of Coats disease. METHODS In a retrospective consecutive series in 150 patients, Coats disease was defined as idiopathic retinal(More)
OBJECTIVE To identify the risk factors that lead to the development of radiation retinopathy following plaque radiotherapy for posterior uveal melanoma. Radiation retinopathy is a slowly progressive, occlusive vasculopathy characterized by radiation-induced endothelial damage. METHODS Review of the medical records of patients with posterior uveal melanoma(More)
There is considerable debate about the significance of choroidal invasion of retinoblastoma with regard to metastatic disease. The charts of patients with retinoblastoma were reviewed over a 17 year period to determine the frequency of histopathological choroidal invasion of retinoblastoma and its risk for eventual metastatic disease. Sixty seven of 289(More)
BACKGROUND Optic nerve invasion is one of the predictors for retinoblastoma metastases. This study was designed to investigate the risk of optic nerve invasion and clinical features that may identify those children with optic nerve invasion. METHODS We reviewed the charts of 289 children with retinoblastoma treated initially with enucleation. Logistic(More)
OBJECTIVE To better define the effect of individual risk factors and combinations thereof on the growth of small choroidal melanocytic tumors. DESIGN Retrospective analysis. SETTING Clinical practice of ocular oncology. PATIENTS The study included 1287 patients with small suspicious choroidal melanocytic tumors, measuring 3 mm or less in thickness,(More)
Previous studies have shown that alcohol ingestion significantly increases human immunodeficiency virus type 1 (HIV-1) replication in peripheral blood mononuclear cells (PBMC) isolated and infected with HIV-1 in vitro. Whether the increased replication of HIV-1 observed after alcohol ingestion was due to unknown factors released from the gastrointestinal(More)
The purpose of this study was to determine whether intravenous or combined intravenous plus oral glucose administration was more effective inducing acute tumour acidification. Seventeen nondiabetic patients at the Henan Tumour Hospital with superficial tumour deposits of various histologies and size were administered, after fasting, either 50 g glucose(More)
The effect of gonadal steroids on the response to analgesia testing was determined in castrated male and female rats and castrated male and female rats treated with testosterone propionate (TP) and estradiol benzoate (EB), respectively. The time to respond to a noxious somatic stimulus in the form of heat was assessed using the tail withdrawal test (tail(More)
The aim of the study was to compare visual assessment of anterior vaginal wall descent with the Q-tip test in evaluating urethrovesical junction mobility. One hundred and eleven patients with prolapse and/or urinary incontinence were examined in the supine lithotomy position with an empty bladder. Maximum straining Q-tip tests and maximum descent of the(More)
