Thermography in diagnosis of radiculopathies

Infrared imaging (thermography) has developed rapidly over the past 10-15 years as a diagnostic imaging procedure. Despite scientific validation and proven use in the clinical setting, neuromuscular thermography has met with much criticism and skepticism. The emotional and political controversy surrounding thermography has distracted the medical community to such an extent that the real issue of utmost importance to the practicing physician is often ignored. The basic scientific foundation of medicine should preclude the prejudicial influence of emotion, politics, and anecdotes. Scientific investigations, for more than 2 decades now, have demonstrated that neuromuscular thermography is of proven value in the clinical evaluation of various pain disorders and neuromuscular conditions, including radicular pathology.     

Lyme arthritis

Evanescent arthralgias and myalgias are common early symptoms of Lyme disease. Transient, intermittent episodes of monoarticular, oligoarticular, or sometimes migratory polyarticular arthritis, lasting weeks to months, with disease-free intervals, are frequently observed in untreated patients with erythema chronicum migrans. A minority of patients develop chronic joint involvement, most commonly affecting the knee. Antibiotic therapy given during erythema chronicum migrans is often protective with regard to late joint manifestations. In chronic Lyme arthritis, however, the response to antibiotics is variable.     

Cardiopulmonary interactions in the cardiac patient in the intensive care unit

Critically ill cardiac patients often undergo mechanical ventilation. The interplay between pulmonary and cardiac mechanics is complicated and in many cases may result in impaired transfer of O2 from the atmosphere to the tissues. This article addresses the principles of pulmonary and peripheral gas exchange, as well as the mechanical effects of respiration on the circulation.     

Pulmonary edema in the renal failure patient

A patient with chronic renal failure presenting to the emergency department with acute pulmonary edema has a true life-threatening emergency. Whereas conventional treatment modalities may prove useful, more unusual therapeutic measures may be necessary. A case is presented followed by useful recommendations for the emergency physician faced with such a patient.     

Effects of preadmission preparation on compliance with home care instructions

This study was conducted to test the effects of preadmission preparation on parent and child psychological upset at the time of tonsillectomy surgery, on child postsurgery behavior, and on parental compliance with home care instructions. Forty children aged 3 to 11 years who underwent tonsillectomy on an outpatient basis were studied. No significant differences were found in parent and child behaviors of those people in the preparation group compared with those in the nonpreparation group. Parental reports of home care revealed that the majority of parents did not follow at least one half of the physicians' home care instructions. The findings of the study indicate the need to further examine factors associated with parental compliance with home care instructions.
