Cardiac tachyarrhythmias are common in thyrotoxicosis. We report an uncommon case of a 53-year-old woman with Grave's disease who developed second degree A-V block while euthyroid on propylthiouracil. The most likely mechanism is an autoimmune response causing infiltration of the cardiac conduction pathways.

Ischemic heart disease (IHD) in women is characterized by a higher morbidity and mortality in the peri-infarction and coronary bypass peri-operative periods. These epidemiological data strengthen our impression that the health system unintentionally "ignores" the high proportion of females with IHD.

The process of investigating chest pain, diagnosing IHD, and the subsequent treatment and rehabilitation, seem to differ between the genders. Time elapsed from beginning of chest pain to diagnosis of IHD seems to be longer in women than in men. Personal, educational and social factors are contributory.

Although time elapsed between diagnosis and rehabilitation is usually similar in the genders, peri-operative morbidity and mortality are higher in women. It may be that the higher rates in women are caused by delay in diagnosis and treatment, which allows worsening of the disease in women before treatment. This delay can occur during the time needed for evaluation of chest pain, from the door of the physician to diagnosis and treatment.

In our retrospective study we determined the difference in referral of men and women with chest pain to the emergency department (ED) and the attitude of physicians in the ED and medical department to chest pain in men and in women, including final diagnosis on discharge. 615 patients over 18 years referred to the ED for chest pain during 3 randomly chosen, consecutive months were studied. We found that women constituted only 39.5% of the referred patients, but the proportion hospitalized was similar to that in men. Hospitalized women were older (57.7±18.4 versus 49.7±17.8 years in men), and had more risk factors (4 versus 2 in men). Proportions of specific diagnoses on discharge from hospital were equal in the genders.

To bridge the differences and to implement education in prevention, investigation and treatment of IHD in women, we established the "Female Heart" clinic. The objective of this clinic is to reduce differences in the first step, in the process of evaluating chest pain in women, by educating and encouraging them to present early to their physicians, and by changing physicians' attituin the investigation of chest pain in women. We plan to determine in a prospective study if these goals are.

Characteristics, Management and Prognosis of Acute Myocardial Infarction (Israel 1990-1996)

Israeli Survey Group On Acute Myocardial Infarction

From 1990 to 1996 we conducted consecutive 2-month surveys in all CCUs (n=26) in Israel. The aim was to compare the characteristics, management, and prognosis of patients with acute myocardial infarction (AMI) between the 4 surveys.

Patient characteristics were similar in all surveys. About 75% of patients were males and had a first MI. Mechanical and arrhythmic complications decreased slightly between 1990 and 1996. In contrast, frequency of treatment with thrombolysis, aspirin, beta-blockers and ACE-I, as well as coronary interventional procedures, increased tremendously.

In parallel, 30-day and 1-year mortality decreased significantly, from 16.5% and 22.5%, respectively, to 9.0% and 13.9%. After multiple adjustment for factors associated with mortality, the 30-day relative risk of death for patients hospitalized in 1992, 1994 and 1996 was 0.79 (95% CI 0.59-1.08), 0.75 (95% CI 0.56-1.01) and 0.54 (95% CI 0.39-9.74), respectively, as compared with 1990.

Although there is no direct proof that changes in management of AMI are related to the reduction in mortality seen during the course of the surveys, the association seems likely.

Our objective was to assess the functional disability of stroke patients by the functional independence measure (FIM) and to examine predictive factors for successful rehabilitation. In 127 consecutive stroke patients efficacy of FIM was 23.9±188, efficiency 0.54±0.45 and 81.9% of patients returned home. Functional improvement was statistically significant (p<0.001) in all FIM domains. Multivariate analysis showed that improvement in FIM score was significantly greater in the younger, among the married, the hemiparetic, and those with an admission FIM of 40-60, while efficiency was related only to type of diagnosis. In addition, the hemiparetic were 3.3 times more likely to return home than the hemiplegic.

We conclude that rehabilitation priorities should be directed towards patients younger than 75 years and to those with an admission FIM of 40-60 points. The results of this study reaffirm the usefulness of the FIM index in assessing stroke rehabilitation.

Carotid sinus syndrome is a well-recognized cause of unexplained syncope in older patients, and may lead to significant morbidity due to trauma from falls. Dual chamber pacing has been shown to be effective in relieving symptoms due to bradycardia, but not due to vasodepressor response. We report an 84-year-old man with recurrent syncope due to carotid sinus hypersensitivity. He was treated only with a serotonin re-uptake inhibitor and was symptom-free after 3 weeks of therapy. He has remained symptom-free for the past year.

Marked obesity is an independent risk factor for multisystem morbidity. The use of anorectic drugs is an aggressive strategy for weight reduction. It appears to be an easy way of dealing with the problem, because the patient needn't change his behavior. However, such treatment is not harmless. At the end of the 60's an outbreak of pulmonary hypertension was associated with the drug aminorex, and it was soon withdrawn from the market. 30 years later it became clear that new-generation anorectic drugs (fenfluramine, dexfenfluramine, phentermine), which were being used world-wide, lead to both pulmonary hypertension and valvular damage.

We describe a woman of 70 with both these complications which developed after prolonged anorectic therapy with a fenfluramine-phentermine combination.

Spectral analysis of heart rate variability (HRV) has been shown to be a reliable noninvasive test for quantitative assessment of cardiovascular autonomic regulatory response, providing a dynamic map of sympathetic and parasympathetic interaction. In a prior study exploring the state of hyperarousal that characterizes the post traumatic stress disorder (PTSD) syndrome, we presented standardized heart rate analyses in 9 patients at rest, which demonstrated clear-cut evidence of a baseline autonomic hyperarousal state.

To examine the dynamics of this hyperarousal state, standardized heart rate analysis was carried out in 9 PTSD patients, compared to a matched control group of 9 normal volunteers. 20-minute ECG recordings in response to a trauma-related cue, as opposed to the resting state, were analyzed. The patients were asked to recount the presumed triggering traumatic event, and the control subjects recounted a significant stressful negative life event.

Whereas the control subjects demonstrated significant autonomic responses to the stressogenic stimulus of recounting major stressful experiences, the patients demonstrated almost no autonomic response to the recounting of the triggering stressful event. The patients demonstrated a degree of autonomic dysregulation at rest comparable to that seen in the control subjects' reaction to the stress model.

The lack of response to the stress model applied in the study appears to imply that PTSD patients experience so great a degree of autonomic hyperactivation at rest, that they are unable to marshal a further stress response to the recounting of the triggering trauma, as compared to control subjects. A subsequent study of the effect of medication on these parameters showed that they are normalized by use of selective serotonin re-uptake inhibitors (SSRI's).

Neither the clinical implications of these findings, nor their physiological mechanisms are clear at present. We presume that they reflect a central effect, as the peripheral automatic effects of SSRI's are relatively negligible.

The incidence of congenital heart defects is 0.8% of live-born infants. Of these 13% are ostium secundum atrial septal defects (ASD) which can be successfully repaired by open heart surgery with less than 1% mortality. However, morbidity associated with cardiac surgery is universal. Transcatheter closure of ASDs was introduced 2 decades ago to decrease surgical complications, hospital stay and cost. Few devices have undergone clinical trials but all of them have been associated with instances of failure and complications. The most important mechanism for acute failure was selection of cases with too large a defect or selection of a defective device. In the past decade great progress has been made with the aid of transesophageal echocardiography (TEE) and modifications of the device. We present our experience in our first 5 patients. They ranged in age from 4 to 27 years; the ASD diameter was 11-15 mm and the device diameter was 17-33 mm. All transcatheter closures were performed on the same day without any complications, and all patients were discharged home after 2 days of hospitalization. We conclude that transcatheter occlusion of ASDs up to 15 mm is feasible, relatively safe and effective. This transcatheter method appears to be a viable alternative to surgery for some patients with secundum atrial septal defects.

Isolated secundum atrial septal defect is one of the most common congenital heart defects. Surgical closure is the treatment of choice but is associated with a chest scar, some morbidity and a relatively long recovery and the use of cardiopulmonary bypass. Transcatheter closure of secundum atrial septal defect is therefor an attractive approach.

3 children, aged 5-10 years, underwent successful transcatheter closure of moderate to large central atrial septal defects with the Cardioseal device. The procedures were performed under x-ray and transesophageal echocardiographic guidance.

Our initial experience, and that of others, indicates that transcatheter occlusion of secundum atrial septal defects is safe and effective and can be an appropriate alternative in approximately 60% of patients.

During 1994/5 the Japanese civilian population suffered 2 terror attacks by the organophosphorus nerve-agent sarin. In these 2 episodes it is estimated that more than 6000 people were injured, of whom 19 died. The quick and efficient response of the civilian emergency systems to these unforseen, attacks has to be analyzed by local authorities to determine the best solutions in case of another attack. We summarize the events, and note the emergency system's response, the need for rapid and accurate chemical identification of the toxin, the necessity for decontaminating the casualties and for providing protective gear for rescue units in the contaminated area. We also describe the clinical status of the casualties and outline the mode of therapy applied.

During the period 1985-95 we treated 5 girls and 13 boys with optic glioma associated with Type 1 neurofibromatosis (median age 3 years, range 2-10 years). 6 were treated with radiotherapy alone, 1 with surgery and radiation therapy and 1 with chemotherapy in order to postpone irradiation to an older age; 1 is being followed with no therapy. All children are alive, 2-10 years from diagnosis (mean follow-up time 5.4 years). 3 had improvement of vision following therapy and in 4 visual ability stabilized, including the child being followed without treatment. In 1 vision deteriorated despite therapy.

Since 1990 we have been admitting mothers with postpartum psychiatric morbidity together with their babies to our open psychiatric ward. The aim of conjoint hospitalization is to maintain and develop the bond between mother and baby while treating the mother's psychiatric disorder. The presence of the infant in the hospital allows both a thorough evaluation of the mothers' maternal ability and to use the infant as a facilitator of the mothers' recovery by engaging maternal functions. It prevents the infants from being placed in a foster home for the duration of the mothers' hospitalization. Readily available in Britain and Australia, such conjoint hospitalization is controversial and rarely available elsewhere. In the past 5 years we hospitalized 10 women with 11 babies (1 woman was hospitalized twice, after different births). All women had received psychiatric treatment prior to childbirth, but this was the first psychiatric hospitalization for 2 of them. Diagnoses (DSM-IIIR) were chronic paranoid schizophrenia (4), disorder (4), schizo-affective schizophrenia (1) and borderline disorder (1). 8 were suffering from active psychotic symptoms on admission. They were treated pharmacologically, received individual and group psychotherapy, and participated in all ward activities. Families were engaged in marital, family and/or individual therapy according to need. All participated in cognitive-behavior treatment tailored to individual need to build and enrich the mother-infant bond. All improved significantly and were able to function independently on discharge, but in 1 case adoption was recommended.

Facial synkinesis is an involuntary activation of muscles innervated by the zygomatic or mandibular branche of the facial nerve in conjunction with voluntary activation of the other branch. It appears frequently after recovery from peripheral facial nerve paralysis. We report 10 patients with facial synkinesis following Bell's palsy with a mean duration of synkinesis of 7±4 years before treatment with periorbital injections of Botulinum toxin type A. 9 had marked subjective and objective improvement starting a few days after injection andlasting 4-9 months. The results suggest a useful treatment option for post-Bell's palsy facsynkinesis with Botulinum toxin type A.

Music is a universal language, and its effects on pain relief and stress reduction are well known. We evaluated patients' opinions of the effects of background music in their family doctors' surgery. Low volume, background, classical music was played in the doctors' surgery on 5 consecutive clinic days. All patients were asked to fill a short anonymous questionnaire on leaving. Among the 135 consecutive patients offered the questionnaire, there was 87.4% compliance. Among the 118 who completed the questionnaire, 95% said that the background music did not disturb them, 89% thought it made them feel better and 80% thought that it aided the doctor's performance. We conclude that low volume, background music in the doctors's surgery may contribute to better doctor-patient interaction, although larger studies are needed to confirm our findings.

A 14-year-old girl with fever and low back pain was diagnosed as having brucellosis and diskitis. Treatment with doxycycline and gentamicin had no effect nor was there any improvement when the treatment was changed to doxycycline and rifampicin. With cessation of this treatment and administration of cloxacillin fever was reduced and the back pain disappeared. After 12 days of IV cloxacillin, she was released from hospital with instructions to continue cloxacillin orally for another 4 weeks. We conclude that when a patient is suffering from brucellosis and diskitis and does not respond to the usual anti-brucellosis treatment, an anti-staphylococcal preparation should be added.
