Acute lymphoblastic crisis in a patient with chronic lymphatic leukemia.

A case of chronic lymphatic leukemia terminating in a lymphoblastic crisis is described. The small lymphocytes were demonstrated to be B cells, they carried immunoglobulins on their surface and formed EAC rosettes. The lymphoblasts had no immunoglobulins on their surface and only 18% of them formed EAC rosettes, none formed E rosettes. The lymphoblasts could be either immature B cells or Null cells.

The intracavitary electrocardiogram: a routine bedside procedure elucidating obscure arrhythmias. A study in 60 patients.

Right heart intracavitary ECG were studied in 60 patients. The procedure is performed by means of a nonmetallic saline-filled catheter introduced percutaneously. It is a simple, quick bedside method requiring minimal equipment. The intracavitary recording visualizes clear and high-voltage P waves, so that a more precise interpretation of complicated rhythm disturbances is possible. It has a distinct advantage over the esophageal lead recording in the differentiation between atrial and ventricular ectopic rhythms. The precise localization of the tip of the catheter used for central venous pressure monitoring can be determined. In 10 patients, doubtful surface ECG diagnoses were confirmed and in 10 others the original ECG interpretation was changed following intracavitary recording. In the remaining 40 patients, the method was used in order to avoid aberrant placement of the central venous pressure catheter.

Listeria monocytogenes pericarditis in a chronically hemodialyzed patient.

We describe the third documented case of Listeria monocytogenes pericarditis. This occurred in a 54-year-old woman with end-stage renal failure on chronic hemodialysis. Her initial presentation was one of Listeria monocytogenes bacteremia, which apparently responded to two weeks of cefazolin sodium therapy. After cessation of therapy the patient returned with Listeria monocytogenes pericarditis, this responding completely to four weeks of erythromycin therapy. We could not rule out coexisting endocarditis, especially since we found high levels of circulating immune complexes which subsided as the patient's condition improved. Further immunological studies displayed a decrease in cellular functions. This case illustrates the importance of Listeria monocytogenes as a human pathogen in immunocompromised patients. Listeria should be included among the potential causative agents of pericarditis in such patients.

Primary visual memory of stroke patients.

This matched control group study assesses primary visual memory of stroke patients using the GEMAT visual-memory test. Primary visual memory of 29 stroke patients who scored 24 or more on the MMSE was compared with that of 33 age and sex-matched controls. Patients were recruited from physiotherapy outpatient clinics. Measured variables were the total time needed to complete the test (GTT) and the number of correct answers (GCA). Patients were slower (p < 0.01) and made more mistakes (p < 0.01) than controls. 'Young' (60-71) subjects made fewer mistakes (p < 0.01) than old subjects (72-89) and patients who scored 24-26 on MMSE were slower than patients who scored 27-30. It should be taken into consideration that stroke patients whose cognitive function is within a normal range of the MMSE might have impaired primary visual memory.
