8†Unexpected retinopathy in a patient presenting with bilateral optic disc swelling.

A 12-year-old boy presented with 5 day history of blurry vision, 'wobbly eyes', tinnitus and difficulty seeing at night. Local ophthalmology noted bilateral optic disc swelling and referred him urgently for neurological investigations.Clinical Findings: At presentation VA was RE 0.00 and LE 0.2 with normal Ishihara colour vision. His extraocular movements were full without manifest strabismus. Fundoscopy showed bilateral optic disc swelling. Electrophysiology unexpectedly revealed a functionally cone isolated retina with markedly abnormal rod function. Pattern VEPs indicated bilateral macular pathway dysfunction affecting left eye more than right eye. Wide field imaging showed bilateral diffusely scattered yellow-white flecks in the midperiphery of each eye. His kinetic visual fields were moderately restricted bilaterally. MRI showed a Chiari 1 malformation with cerebellar tonsil herniation, but LP opening pressure was normal.Differential diagnosis included RDH5 retinopathy or vitamin A deficiency. On questioning he reported a diet restricted to only meat and biscuits. His vitamin A levels were subnormal at 0.14 umol/L (reference range 0.9-2.5umol/l) and he was started on high-dose Vitamin A supplements.Four months after supplementation retinal appearances had normalised, the rod ERGs recovered, nyctalopia and visual field restriction resolved. PVEPs had improved but an element of LE macular pathway dysfunction remained. Optic disc swelling settled leaving mild temporal pallor, particularly of the LE with some RNFL loss.It is important to recognise nutritional Vitamin A deficiency in children as prompt recognition and treatment can improve symptoms, reverse retinal pathology which we have demonstrated with electrophysiological findings.

Complementary and alternative medicine use in patients with gynecological cancers in Europe.

The aim of the present study was to assess the use of complementary and alternative medicine (CAM) specifically in women with gynecological cancer. The design of the study was of a descriptive cross-sectional survey using a 27-item questionnaire. The study was conducted in 11 countries in Europe as part of a larger project. Data were available from 72 gynecological cancer patients. Among the participants, 40.3% used CAM after the diagnosis with cancer. The most popular CAM modalities used were herbal medicine (34.5%), relaxation techniques (21.4%), and vitamins/minerals (20.7%). A very high level of satisfaction with CAM use was reported. Patients used CAM to increase the body's ability to fight the cancer or to improve physical and emotional well-being. The main sources of information about CAM were informal (friends/family or the media). It is important to discuss CAM use with gynecological cancer patients, as they frequently use it and such use may have implications for clinical practice.

Complementary and alternative medicine use in patients with head and neck cancers in Europe.

The aim of the present study was to examine the patterns of complementary and alternative medicine (CAM) use in a sample of head and neck cancer patients, forming part of a larger study. A cross-sectional survey design was used collecting data through a descriptive 27-item questionnaire in nine countries in Europe. The participants were 75 patients with head and neck cancers. The prevalence rate of CAM use was 22.7%. The most common therapies used were herbal medicine (47%), medicinal teas (23.5%), use of vitamins/minerals (11.8%) and visualization (11.8%). Use of CAM dramatically increased after the diagnosis with cancer (i.e. eightfold increase in the use of herbs). A profile of CAM users was not evident in this sample. Patients used CAM for a variety of reasons together, with counteracting the ill effects from cancer and its treatment being the most common one. Information about CAM was obtained mostly from friends and family. As one in five head and neck cancer patients use CAM it is important that clinicians explore practices with their patients, improve communication about CAM with them and assist those who want to use CAM in using appropriate and safe therapies.

Use of complementary and alternative medicine in cancer patients: a European survey.

BACKGROUND: The aim of this study was to explore the use of complementary and alternative medicine (CAM) in cancer patients across a number of European countries. METHODS: A descriptive survey design was developed. Fourteen countries participated in the study and data was collected through a descriptive questionnaire from 956 patients. RESULTS: Data suggest that CAM is popular among cancer patients with 35.9% using some form of CAM (range among countries 14.8% to 73.1%). A heterogeneous group of 58 therapies were identified as being used. Herbal medicines and remedies were the most commonly used CAM therapies, together with homeopathy, vitamins/minerals, medicinal teas, spiritual therapies and relaxation techniques. Herbal medicine use tripled from use before diagnosis to use since diagnosis with cancer. Multivariate analysis suggested that the profile of the CAM user was that of younger people, female and with higher educational level. The source of information was mainly from friends/family and the media, while physicians and nurses played a small part in providing CAM-related information. The majority used CAM to increase the body's ability to fight cancer or improve physical and emotional well-being, and many seemed to have benefited from using CAM (even though the benefits were not necessarily related to the initial reason for using CAM). Some 4.4% of patients, however, reported side-effects, mostly transient. CONCLUSIONS: It is imperative that health professionals explore the use of CAM with their cancer patients, educate them about potentially beneficial therapies in light of the limited available evidence of effectiveness, and work towards an integrated model of health-care provision.
