[Falls in elderly patients in an institution].

Falls among the elderly are a major concern of those caring for them. We studied the incidence of falls in institutionalized elderly, as well as the characteristics of those who fell and the causes of the falls, to determine how to prevent falling. A 2-month survey was conducted in Mishan, an institution in Raanana, and included 144 falls in 108 patients (447 women and 162 men, mean age 84) out of a total of 609 elderly. The prevalence of falls was 1426 per 1000 per year. Most cases of falls were first seen in the emergency room or wards for demented patients. The prevalence of falls among those receiving physiotherapy was only 1/3 that of those who did not. Old institutionalized patients tend to fall mainly while getting in and out of bed. Falls may result from medication such as sleeping pills and psychotropic drugs, but not diuretics. Falls are not inevitable, and measures can be applied to prevent them and thus reduce their frequency.

Detection of anti-red blood cell antibodies by treatment of the cells with neuraminidase.

Neuraminidase treated RBC were used to detect incomplete unbound anti RBC antibodies in the plasma of patients with immune diseases. 80% (48 out of 60) of the examined patients gave positive results with this method while all the 50 normal controls were negative. The indirect antiglobulin test was negative in all the patients. In the direct antiglobulin test only two RBC samples, whether treated with neuraminidase or not, gave positive results. The present study indicates that the assay of plasma on neuraminidase treated RBC may serve as a sensitive method for the detection of the presence of anti RBC antibodies in various immunological diseases.

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.
