Pathologic flail chest complicated the initial presentation of multiple myeloma in two patients. Both had severe hypercalcemia and diffuse bone disease. ⋯ However, delay in stabilizing the first patient's chest wall with positive airway pressure was followed by extension of the flail chest and irreversible respiratory failure. On the other hand, prolonged stabilization of the chest wall in the second patient until a chemotherapy-induced remission occurred was associated with resolution of the flail chest.

There is evidence that man has suffered from tuberculosis for more than 5,000 years, and through crowded living conditions, debilitation, and malnutrition, tuberculosis became epidemic in Western civilization and was a major cause of mortality. Identification of the tubercle bacillus as the causative agent in 1882 firmly established the infectious nature of the disease and the development of sanatoriums soon followed. ⋯ Despite these effective chemotherapeutic and preventive agents, tuberculosis has receded to socioeconomically disadvantaged urban and rural areas, where the incidence parallels that of developing countries. Conquest of the disease will require improved health care delivery to the indigent and dispossessed.

Charcot-Marie-Tooth disease (peroneal muscular atrophy) has been reported to cause cardiac arrthymias and conduction disturbances in association with peripheral muscle atrophy. To establish more accurately the frequency of such cardiac disorders in this disease, 68 patients with Charcot-Marie-Tooth disease were evaluated prospectively for evidence of cardiac involvement. ⋯ The frequency of each of the abnormal cardiac findings, with the possibly emalities in the population at large. The low incidence of cardiac involvement in patients with Charcot-Marie-Tooth disease may be helpful in distinguishing this disorder from Friedreich's ataxia, an entity that may mimic Charcot-Marie-Tooth disease but that is frequently associated with heart disease.
