Cotton dust lung diseases.

Ahmed J. Khan; Rahul Nanchal

Purpose of review Although, in the industrialized world, there is a significant decline in the prevalence of cotton dust lung diseases, studies show an increasing incidence in the developing world. With rapid industrialization of the developing world, cotton dust-induced lung diseases are poised to become a global health problem. Discovery of other vegetable dusts causing similar conditions and appreciation of a wider variety of clinical features also make this an opportune time to review this topic. Recent findings In addition to chronic exposure-related byssinosis and less common forms of acute byssinosis, recent reports describe the rare occurrence of cotton dust-induced pulmonary fibrosis. New data also relate long-term cotton dust exposure to symptoms and physiologic changes of chronic obstructive pulmonary disease. There have also been new developments relating the pathogenesis of cotton dust airway disease to endotoxin lipopolysaccharide found in cotton dust and bract extracts. Summary Establishment of an association between prolonged exposure to cotton and other vegetable dusts and symptoms of chronic obstructive pulmonary disease widens the clinical implication of cotton dust exposure. In addition, accumulating knowledge of endotoxins will bring about promising new developments reshaping industrial safety standards and measures to prevent cotton dust exposure.

Wellness assistant: a virtual wellness assistant using pervasive computing

Sheikh Iqbal Ahamed; Munirul M. Haque; Karl Stamm; Ahmed J. Khan

The number of people over age 65 will almost double by 2030 and as they age, they generally prefer to remain in their home or go to a nursing home. There are a variety of reasons for their decision, such as convenience or a need for security or privacy. So, it is time to break through the physical boundaries of hospitals, and bring the hospital information to the homes of the elderly rather than bringing elderly folks to the hospital. Despite growing requests by people to be able to take a more active part in managing their own health, wireless or internet-based healthcare devices have not been accepted for use in this area. This is probably due to the reluctance of this age group to make use of new technology, as well as the lack of reliable, individualized, or user friendly interfaces. In this paper, we discuss the challenges of developing Wellness Assistant (WA), software which is looking to solve some of these problems. The Assistant will use pervasive computing technologies because of the availability of inexpensive handheld devices such as PDAs, cell phones, and wrist watches with short range wireless capabilities. The WA can also be used by people with obesity, diabetes, or high blood pressure, conditions which need constant monitoring.

High Use Rate of Chest Imaging in Hospitalized Patients and Its Dramatic Increase With Length of Stay

Eman Albaddawi; Zahia Esber; John Wright; Ahmed J. Khan

PURPOSE: Widespread use of ‘routine’ imaging studies in the hospital setting is concerning. It is a common practice to obtain a routine chest X Ray with each admission, many times without a valid indication. Many such studies require follow up or further clarification, which lead to subjecting the patient to more imaging studies and invasive tests of varying modality. In this retroscpective chart review, we aim to assess the estimated number of chest X-Ray (CXR), Computed Tomographic Scan of chest (CT) performed and resulting ionizing radiation exposure among a random group of patients admitted with respiratory symptoms in our institution. Although the focus of this study was chest imaging and hence patient cohort with respiratory symptoms were selected, we anticipate the trend would be similar in case of head, abdominal or extremity imaging studies among the patients admitted respectively with head, abdominal and extremity symptoms.
