Frail and vulnerable elderly patients, recognized primarily by the presence of such disabilities as immobility, incontinence, and dementia, are at particularly high risk for the development of infectious diseases, which are the leading cause of hospitalization in this population. The infectious diseases most often observed in the debilitated elderly are pneumonias, urinary tract infections, skin infections, and gastroenteritis, with fever a common manifestation. Some of the factors identified as contributing to their increased susceptibility include diminishing physiologic functioning; compromised host-defense mechanisms; increased incidence of mechanical risk factors, such as pressure ulcers, indwelling or condom catheters, feeding tubes, and soft tissue injuries; and comorbidities such as soft tissue or pulmonary edema. In addition to the common infecting pathogens found in the general population, these unique compromising factors increase the risk of elderly patients for aerobic gram-negative bacillary infection. Further increasing the therapeutic dilemma are ethical considerations involved in prolonging treatment that might be considered medical intervention beyond what is routine and necessary. Although the decision to treat must be made on an individual basis, studies have not always shown treatment to provide benefits in terms of quality of life. Once it is decided to treat, however, appropriate therapy is crucial. One of the most important considerations is renal function, which impacts on effectiveness, toxicity, and cost of therapy and is likely to be diminished in elderly patients. A non-nephrotoxic agent, such as aztreonam, may be a more appropriate therapeutic choice than an aminoglycoside antibiotic in this patient population.

Carbon monoxide (CO) has the toxic effects of tissue hypoxia and produces various systemic and neurological complications. The main clinical manifestations of acute CO poisoning consist of symptoms caused by alterations of the cardiovascular system such as initial tachycardia and hypertension, and central nervous system symptoms such as headache, dizziness, paresis, convulsion and unconsciousness. CO poisoning also produces myocardial ischemia, atrial fibrillation, pneumonia, pulmonary edema, erythrocytosis, leucocytosis, hyperglycemia, muscle necrosis, acute renal failure, skin lesion, and changes in perception of the visual and auditory systems. Of considerable clinical interest, severe neurological manifestations may occur days or weeks after acute CO poisoning. Delayed sequelae of CO poisoning are not rare, usually occur in middle or older, and are clinically characterized by symptom triad of mental deterioration, urinary incontinence, and gait disturbance. Occasionally, movement disorders, particularly parkinsonism, are observed. In addition, peripheral neuropathy following CO poisoning usually occurs in young adults.
