Treatment of cutaneous leishmaniasis by direct current electrotherapy: the Baghdadin device.

Electrical stimulation has been used as a mode of therapy for a number of clinical conditions. However, it has not been used for the treatment of cutaneous leishmaniasis (CL). For this purpose, we designed the "Baghdadin device". A total of 146 lesions of acute CL in 54 patients were treated by this device. Twenty-one lesions in the same patients were left untreated as controls. In addition, 36 lesions in 15 patients were treated with intralesional sodium stibogluconate. Treatment by the Baghdadin device consisted of weekly sessions of 10 minutes of direct current electrical stimulation. The intensity of the direct current ranged between 5 and 15 milliamperes, and the voltage was kept below 40 volts. Of the 146 lesions, 135 (92.5%) showed total clearance or marked improvement in 4-6 weeks time. Approximately 67% of the lesions needed only one or two sessions. Scarring was not observed after resolution. None of the untreated lesions showed any signs of improvement in 6 weeks. Of the lesions treated with sodium stibogluconate, 32 lesions (88.9%) showed total clearance or marked improvement, which was not significantly different from the results with the Baghdadin device.

We have come a long way with device therapy: historical perspectives on antiarrhythmic electrotherapy.

The history of device therapies is long and fascinating. In the beginning, there is not simply the anatomy and physiology of the heart, but also analysis of the pulse, which indicates the activity of the heart. The analysis of the (peripheral) pulse as a mechanical expression of heart activity goes back several millennia. In China, in 280 BC, Wang Shu He wrote 10 books about the pulse. The Greeks called the pulse "sphygmos"; thus, sphygmology deals with a theory of this natural occurrence. In Roman times, Galen interpreted the various types of pulse according to the widespread presumption of the time that each organ in every disease has its own form of pulse. The growing clinical importance of electrical cardiac stimulation was recognized and renewed as Zoll in 1952 described a successful resuscitation in cardiac standstill by external stimulation. Meanwhile, millions of patients with cardiac arrhythmias worldwide have been treated with pacemakers in the last 40 years. The concept of a fully automatic implantable cardioverter defibrillator system for recognition and treatment of ventricular tachyarrhythmias was first suggested in 1970. The first implantation of the device in a human being was performed in February 1980. Further developments involved atrial and atrioventricular defibrillators, radiofrequency ablation, laser therapy, and advanced antiarrhythmic surgery. Since 1990, there has been a growing interest in using cardiac pacing as additional treatment in severe cardiac failure. Recent reports have suggested that intervention with left ventricular or biventricular pacing may be helpful for a subgroup of patients with congestive heart failure. Despite encouraging (preliminary) acute and short-term results, pacing strategies for heart failure still are limited and currently regarded as investigational. Advances in the field of therapeutic application of pharmacologic and electrical tools as well as alternative methods will continue as rapidly as before and provide us further significant aid in taking care of patients.

A fiberoptic sensor system for cardiac monitoring and electrotherapy.

Commercially available cardiac pacemakers and implantable cardioverters/defibrillators (ICD) predominantly use the intracardiac derived electrocardiogram (ECG) for detection of arrhythmias. To achieve an automatic control of the heart frequency in accordance with cardiovascular strain and an improved detection of life-threatening arrhythmias, it is desirable to monitor the heart by an input signal correlated with the hemodynamic state. One possible approach to derive such a signal, is to measure the inotropy (mechanical contraction strength of the heart muscle). For this purpose an optoelectronic measurement system has been designed. The fundamental function of the system has been shown in earlier investigations using an isolated beating pig heart. In this paper further results showing the correlation of the fiberoptic sensor signal with the left ventricular stroke volume are presented. To make the system useful for implantable devices, further improvements with regard to power consumption and signal quality were achieved.
