A complicated chinese herbal medicine nephrotoxicity.

Chinese herbal medicine is widely used globally. In many instances, it is associated with severe adverse outcomes. We report case of a Chinese herbal nephropathy occurring in a 43-year-old woman showing renal impairment, metabolic acidosis, Stokes - Adams syndrome, hypernatremia, and hypokalemia, characteristics not usually encountered in published cases.

Adams-Stokes attack as the first symptom of acute rheumatic fever: report of an adolescent case and review of the literature.

BACKGROUND: Acquired complete heart block, in pediatric age is mainly the results of direct injury to conduction tissue during cardiac surgery or cardiac catheterisation. It can also be observed in different clinical settings as infectious diseases, neoplasia, and inflammatory diseases. It has a wide range of presentation and in some settings it can appear a dramatic event. Although a rare finding during acute rheumatic fever, with a transient course, it may need a specific and intensive treatment. CASE PRESENTATION: We report the case of an Adams-Stokes attack in an adolescent with acute rheumatic carditis and complete atrio-ventricular block. The attack was the first symptom of carditis.We reviewed the literature and could find 25 cases of complete atrio-ventricular block due to rheumatic fever. Ten of the 25 patients experienced an Adams-Stokes attack. Nineteen of the 25 patients were certainly in the pediatric age group. Seven of the 19 pediatric cases experienced an Adams-Stokes attack. In 16/25 cases, the duration of the atrio-ventricular block was reported: it lasted from a few minutes to ten days. Pacemaker implantation was necessary in 7 cases. CONCLUSION: Rheumatic fever must be kept in mind in the diagnostic work-up of patients with acquired complete atrio-ventricular block, particularly when it occurs in pediatric patients. The insertion of a temporary pacemaker should be considered when complete atrio-ventricular block determines Adams-Stokes attacks. Complete heart block during acute rheumatic fever is rare and is usually transient. Along with endocarditis, myocarditis and pericarditis, complete atrio-ventricular block has been recognized, rarely, during the course of acute rheumatic carditis.

Aubrey Leatham and the introduction of cardiac pacing to the UK.

In the early 1950s, Dr Aubrey Leatham established a cardiac unit at St. George's Hospital, Hyde Park Corner, London. He developed and taught the essential clinical skill of cardiac auscultation. Under his guidance a clinical department for the care of cardiac patients was developed and coupled to physiological academic research. He was a pioneer in cardiac pacing and, in 1961, Harold Siddons, O'Neal Humphries, and Aubrey Leatham implanted the first 'indwelling' pacemaker in the UK in a 65-year-old man with repeated Stokes-Adams attacks due to complete heart block. The nickel-cadmium 'accumulator', which powered the pacemaker, had to be recharged once a week.

Cardiac pacemaker treatment of heart block in Enugu a 5-year review.

BACKGROUND: Symptomatic heart block is a treatable cardiac cause of death which occurs globally. In Nigeria it is increasingly diagnosed and treated with permanent artificial cardiac pacemaker insertion and pulse generator implantation, sometimes after a period of misdiagnosis and inappropriate treatment. METHODS: Twenty-three patients who were diagnosed with symptomatic heart block and surgically treated with permanent artificial cardiac pacemaker in National Cardiothoracic Centre, Enugu, between April 2001 and March 2006 had their case notes retrospectively reviewed and information entered into a proforma. This was analyzed. Patients diagnosed with symptomatic heart block but not treated with artificial cardiac pacemaker insertion were excluded from the study. There were eight such patients who could not afford the cost of surgical treatment during the period under review. RESULTS: The mean age of the patients was 70 years and the commonest presentation was shortness of breath (100%). Hypertensive heart disease was present in 65% of the patients and a history of chronic chloroquine usage was positive in 73% of the patients. Predominant pretreatment pulse rate was in the range of 30-40 per minute (43%) while 21% of the patients had pulse rate below 30 per minute. These categories of patients commonly had Stoke-Adams syndrome. Sixty-seven per cent of the patients had predominantly systolic hypertension on admission and 16% had hypotension. Third degree heart block was present in 65% of the patients and 89% of all patients needed pre-pacing haemodynamic stabilization with positive inotropic/chronotropic drug(s). Treatment consisted of permanent endocardial pacing in 65% and epicardial pacing in 35% of the patients with equally good response in symptoms, haemodynamic parameters and electrocardiographic features. CONCLUSION: Permanent artificial cardiac pacing is, the reliable treatment of symptomatic heart block and should be included in the National Health Insurance Scheme list.

[Morgagni-Adams-Stokes after adenosine injection in a patient with WPW syndrome--a case report]. / Zespól Morgagni-Adams-Stockesa po wstrzyknieciu adenozyny u pacjentki z zespolem WPW.

A case of a 16-year-old girl with left sided accessory pathway is presented. Following adenosine-induced termination of atrio-ventricular reentrant tachycardia the patient developed polymorphic ventricular tachycardia followed by preexcited atrial fibrillation with very rapid ventricular response and syncope. Arrhythmia was terminated by amiodarone infusion. Potential complications after adenosine injection are discussed.

We report a case of Prinzmetal angina initially manifested with short losses of consciousness in a 55-year-old man hospitalized in the Department of Coronary Artery Disease, Institute of Cardiology, Jagiellonian University Medical College in Cracow. Clinical symptomatology of the presented case, causes and mechanism of loss of consciousness in variant angina as well as treatment methods are discussed.

[Malfunction of a permanent pacemaker]. / Disfunción de marcapaso definitivo.

Forty years have gone by since the first pacemaker implant; this fact had strong impact in the life of thousands of persons. The objective of this work is to report the case of definitive pacemaker malfunction with epicardiac lead and review the literature concerning the important aspects of the causes and diagnosis of pacemaker malfunction. We consider that physicians dealing with patients implanted these devices must be prepared to diagnose and treat them adequately.

[The use of an implantable ECG recorder in the diagnosis of puzzling sporadic syncopes]. / Gebruik van een implanteerbare ECG-recorder bij de diagnostiek van onbegrepen wegrakingen.

A 70-year-old man had passed out three times in six years, and was suspected of having a rhythm or conduction disturbance. Repeated hospitalization with telemetric monitoring had not revealed any disease. An implantable ECG recorder finally revealed the occurrence of symptomatic sinus arrest (Adams-Stokes attack), a month after discharge from the hospital. The patient was treated with a pacemaker. The cause of recurrent syncope can be difficult to diagnose. There is always a danger of overdiagnosis or under-treatment. Prospective study and cost effectiveness analysis are needed to determine the proper place of the implantable ECG recorder in the diagnosis of this disease.

Acute nonspecific carditis in adolescents presenting with Stokes-Adams attacks.

Three patients, aged between 12 and 17 years presented with Stokes-Adams attacks as a result of atrioventricular block, atrioventricular silence and ventricular arrhythmias, complicating acute myocarditis. All the patients required temporary pacing for a few days. One patient required hemodialysis for anuria. All the patients made complete recovery.

[The runaway pacemaker syndrome during electrical ventricular stimulation of the heart]. / Sindrom "ubegaiushchego élektrokardiostimuliatora" pri élektricheskoi zheludochkovoi stimuliatsii serdtsa.

The paper reports a case of escaping pacemaker syndrome in a female with continuous endocardial ventricular pacing. The syndrome was provoked by defects in the electronic scheme because of weakening of pacemaker's battery.

Recurrent syncope of unknown origin: value of permanent pacemaker insertion.

We studied the outcome of permanent pacing in those with a history suggestive of Stokes-Adams attacks but no electocardiographic evidence of bradyarrhythmia. Of 11 patients who fulfilled pre-defined inclusion criteria, over a mean follow-up period of 5.4 years, seven patients were free of symptoms and two were much improved following pacing. We suggest that in those with a clinical history of frequently recurrent Stokes-Adams attacks and a normal electrocardiogram, pacemaker insertion may be a reasonable course of action.
