RESUMO
This is an attempt to review the current major thyroid disorders that may affect the heart directly and/ or indirectly and their prognostic pattern. It is accepted that cardiac disability can occur in thyroid dysfunction in the absence of any other underlying cardiac abnormality. This "Thyrocardiac disease" occurs more commonly within creasing age and in the elderly and may reflect occult thyroid function impairment. The advent of non-invasive cardiology particularly cross-sectional echocardiography has demonstrated ability to assess ventricular internal dimensions and function and to detect various cardiac disorders in the so called thyroid heart disease. Nevertheless great awareness has been reached in the age long controversy regarding the magnitude of cardiac abnormality in thyroid disorders

A retrospective study was carried out to estimate the magnitude and pattern of foot lesions seen in diabetics living in Saudi Arabia. A review of the records of 1010 diabetic patients seen at King Khalid University Hospital, Riyadh, revealed an overall prevalence of 10.4% for diabetic foot lesions. Of these, 88 patients were further characterized; 55 [62 .5%] were males and 33 [37.5%] were females. Seventy-five patients [85.2%] were Saudis and 13 [14.8%] were non-Saudis. The average age was 58 years. Eighty-five patients had type 2 diabetes and three had type 1. The spectrum of foot lesions included: 10 cases of cellulitis, 33 cases of ulcers, 29 cases of gangrene, and 16 cases of abscess. Evidence of peripheral vascular disease was present in 48 patients [54.5%] while peripheral neuropathy was found in 43 [48.8%]. Surgical debridement with prolonged dressing was done in 58 patients [66%] while amputation was performed in 30 [34.1%]. The average hospitalization was 6.8 weeks. Diabetic foot lesions constitute a major complication of this disease in Saudi Arabia. The high amputation rate is a source of concern and improved techniques are urgently needed to reduce this serious outcome
