The Clock Drawing Test (CDT) is a simple neuropsychological screening instrument that is well accepted by patients and has solid psychometric properties. Several different CDT scoring methods have been developed, but no consensus has been reached regarding which scoring method is the most accurate. This article reviews the literature on these scoring systems and the changes they have undergone ...

We present the case of a patient with an infection by Nocardia which manifested itself with monocular endophthalmitis. Nocardia infection is not common and ocular involvement is one of the most uncommon presentations. In these cases it is very important to make an early diagnosis and intensive treatment to prevent the visual prognosis.

Methods for control and prevention should entail a systematic plan for treating affected foals, screening for early detection of infected foals not manifesting clinical signs, and preventing new cases. Plans need to be tailored to the specific needs and resources of individual farms. Author’s address: Department of Large Animal Medicine and Surgery, College of Veterinary Medicine, Texas A&M Uni...

The urinary excretion of hydroxyproline, measured as the hydroxyproline: creatinine ratio, was useful in monitoring the progression of metastatic cancer of the breast. After new treatment was started changes in the hydroxyproline excretion occurred earlier than other clinically observable responses. The test could therefore be used for predicting the response to treatment and early detection of...

OBJECTIVES To investigate the frequency of malnutrition and associated factors in patients over 65 years of age in a hospital. METHODS We conducted an observational, crosssectional and descriptive study. Department of Nutritional Support, Hospital Medica Sur, Mexico, we evaluated patients over 65 years of age within the first 24 hours of admission. RESULTS We evaluated 769 patients, 49% of ...

Alzheimer's disease (AD) is the most common cause of dementia affecting 36 million people worldwide. As the demographic transition in the developed countries progresses towards older population, the worsening ratio of workers per retirees and the growing number of patients with age-related illnesses such as AD will challenge the current healthcare systems and national economies. For these reaso...

Early detection and excision is the only effective treatment for malignant melanoma. To assess the effect of a consultant-delivered, rapid-access pigmented lesion clinic (PLC) established at the South Infirmary-Victoria University Hospital (SIVUH), we analyzed melanoma tumour-stage prior to (1998-2002) and after (2003-2007) the advent of the PLC. Patients attending SIVUH had a greater proportio...

These two categories complement each other as they are used in different phases of the design process. The advantage of simulation-based fault injection is that it can be employed early in the design, which facilitates early detection of design faults, which thus reduces the cost for correcting such faults. It also provides a high degree of controllability and observability. The main drawback t...

The Budd-Chiari Syndrome is associated with hepatic venous outflow obstruction. This syndrome is rare in infants and children. As this syndrome is uncommon, especially in the paediatric age group, misdiagnoses and delays in the diagnosis are frequent. A high index of clinical suspicion along with a radiological aid and a histopathological correlation can lead to an early diagnosis and an approp...

National cancer control plans are needed to stem the rapidly rising global cancer burden. Prevention and early detection are complementary but distinct strategies for cancer control. Some cancers are prevented through behavior and/or environmental modifications that reduce cancer risk, whereas other cancers are more amenable to treatment when they are successfully diagnosed at early stages. Pre...
