We report three cases of localized thrombotic purpura that appeared during the convalescence phase of common chickenpox. This rare complication is characterized by localized symmetric ecchymotic purpura often affecting the lower limbs and often accompanied with signs of disseminated intravascular coagulation. In two cases we found transient protein S deficiency.

Acalculous cholecystitis is a life-threatening complication in critically ill surgical patients. Whereas Candida albicans and Torulopsis glabrata have been reported as the primary pathogens in 14 previous cases of acalculous cholecystitis, we report the first case of Candida parapsilosis as a biliary pathogen in a patient after cardiac transplantation. Although cardiac transplant recipients often have many of the risk factors for acalculous candidal cholecystitis, including major surgery, immunosuppression, antibiotic therapy, parenteral nutrition, and prolonged intensive care unit stay, this entity has not been previously reported in the cardiac transplant population. Although rare, acalculous candidal cholecystitis is associated with very high morbidity and a mortality rate of 40%. Early diagnosis necessitates an aggressive approach to the critically ill patient with abdominal complaints. Prompt drainage or cholecystectomy, if possible, represent the mainstays of therapy and offer the greatest chance for survival.

Timing abnormalities of myocardial contractility may occur as inter- or intraventricular asynchrony. Gated blood pool scintigraphy was performed on 21 patients with a normal ejection fraction and the following electrocardiograms: six normal, six with left bundle branch block, four with right bundle branch block and five with right ventricular pacemaker rhythm. A phase and amplitude of the first harmonic of the Fourier transform was obtained for each pixel, and left and right ventricles were trisected. A mean vector phase for each region was obtained by vector summation. Regional and global values were analyzed within each group and compared with normal values. The phase differences between the entire left and right ventricles (mean +/- standard deviation) were: 9 +/- 3 in the normal patients, 38 +/- 8 (p less than 0.01) in patients with left bundle branch block, -6 +/- 7 (p less than 0.05) in patients with right bundle branch block and 15 +/- 9 (difference not significant) in patients with pacemaker rhythm. The phase differences between left ventricular posterolateral and septal regions were -4 +/- 2 in the normal patients, 10 +/- 5 (p less than 0.01) in patients with left bundle branch block, -7 +/- 10 (p less than 0.05) in patients with right bundle branch block and 10 +/- 5 (p less than 0.01) in patients with pacemaker rhythm. Within the right ventricle, phase differences between the apical and septal segments were 14 +/- 9 in the normal patients, 14 +/- 10 (NS) in patients with left bundle branch block, -2 +/- 3 (p less than 0.01) in patients with right bundle branch block and -22 +/- 18 (p less than 0.01) in patients with pacemaker rhythm. Interventricular phase differences were greatest in patients with left bundle branch block and absent or reversed in right bundle branch block.(ABSTRACT TRUNCATED AT 250 WORDS)

PURPOSE: The purpose of this report is to present behavioral interventions to assist persons with lung cancer in the management of feelings of breathlessness and, thus, also to enhance their quality of life. OVERVIEW: Breathlessness is a serious symptom that adversely affects the quality of life of persons with lung cancer. A review of the literature points to the value of exercises in assisting patients to breathe more effectively and to manage related anxiety. However, the professional literature frequently does not describe these basic interventions in enough detail to enable oncology professionals to learn them. Instructional materials, found in the popular wellness and self-help literature, are included in this article to more easily facilitate acquisition of these skills. Interventions described include exercises that enhance the use of the diaphragm when breathing and those that help to alter the breathing rhythm and to exhale more effectively. CLINICAL IMPLICATIONS: All oncology professionals should be aware of the importance of breathlessness as a problem that diminishes the quality of life for patients with lung cancer. Addressing breathlessness through the use of psychosocially oriented behavioral interventions can act as an adjunct to the medical management of this debilitating symptom.
The authors report the clinical and laboratory findings of a patient who had severe immune hemolytic anemia due to hydrochlorothiazide (HCTZ). In this case, the HCTZ antibody reacted not only with other thiazide and thiazide-like drugs, but also with a chemically unrelated diuretic, ethacrynic acid. These results indicate that HCTZ antibody activity is not restricted solely to the thiazides and imply that therapy with any of the reactive drugs would be contraindicated for this patient. The serologic screening for drug reactivity may be useful for selecting alternative therapy for patients with drug-induced immune hemolytic anemia.
