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.

Brucellosis is a classical zoonosis caused by a Gram-negative bacillus of the genus Brucella. Human brucellosis can either be acute or chronic and present with a variety of manifestations, mostly with fever and signs of musculo-skeletal involvement. It may be complicated by involvement of the cardiovascular, central nervous or genito-urinary systems. However, pulmonary brucellosis is a rare complication.

We report a case of miliary and reticulo-nodular brucellar pneumonia with positive blood and sputum cultures and positive serological tests. To the best of our knowledge this is the first case to be reported from Israel of miliary pneumonia with sputum positive for brucellosis.

Spontaneous internal jugular thrombosis is a rare vascular disorder. It usually occurs as a result of external pressure due to a tumor, infection or as a result of damage to the vessel wall after trauma or central venous catheterization. We report a 35-year-old woman who suffered from severe pulmonary hypertension due to chronic cystic lung disease. She was admitted due to sudden, severe, right-sided neck pain. Internal jugular occlusion by a thrombus was demonstrated by ultrasound and CT-scans but no apparent cause was found. We postulated that the important factors in the development of her thrombosis were stasis due to pulmonary hypertension and high blood viscosity.

Urinary tract infection (UTI) is the most common bacterial infection during pregnancy. In prenatal and delivery wards treatment is usually started at once in pregnant women with symptoms suggesting UTI, but there is no uniformity as to treatment. We surveyed such treatment in the delivery rooms throughout Israel, and whether the treatment differed in simple cystitis as opposed to pyelonephritis. Results of positive urine cultures from symptomatic parturients admitted here during 1995-1996 were examined.

There were 17 different empiric treatment protocols in 28 delivery rooms, whose daily cost ranged from 1-119 NIS. We present the antimicrobial sensitivity of 156 bacteria isolated from the urinary cultures from pregnant women in our prenatal ward. Based upon urinary flora, sensitivity and daily cost, we suggest a protocol for empiric treatment. We recommend first and second generation cephalosporins for treatment of simple lower (UTIs), while gentamicin is suggested for treatment of clinical pyelonephritis during pregnancy. There is no medical nor economic justification for the multiplicity of empiric treatment protocols currently used. Considering our results, our protocol is cost-effective for the empiric treatment of UTI in hospitalized parturients and in the community as well.

The Surgeon and the Emperor: a Humanitarian on the Battlefield

The Baron Dominique-Jean Larrey, one of the greatest names in military surgery, participated as Chief Surgeon in all the Napoleonic campaigns. He developed the concept of early evacuation from the battlefield, and of immediate treatment of the wounded, even under fire. He implemented improved surgical techniques and improved wound care that were followed by surgeons all over Europe. His devotion to wounded soldiers crossed national boundaries and became a way of life. Here is an account of Larrey's involvement in the aftermath of the Battles of Lutzen and Bautzen (May-June 1813), when many soldiers were accused of self-mutilation and were about to be executed. He dared to oppose, singlehanded, the Emperor, the highest military authorities and their concurring physicians and surgeons, armed only by his undisputed honesty, professional authority and exceptional reputation won over years of devotion to wounded soldiers. Larrey saved the lives of many soldiers and set an example of unbent ethical integrity.

The accidental exposure of the health care workers (HCW) to blood and blood products constitutes a danger for transmission of blood-borne pathogens and the development of severe diseases. Most attention is focused on exposure to the viruses of hepatitis B, C and human immunodeficiency. The objectives of this prospective study were to determine the rate of exposure of our HCW to blood and blood products; to define the high risk groups; and to establish recommendations to prevent transmission or reduce the risk of exposure to these viruses.

During the year 1996, 103 injuries from needle-puncture or other sharp objects were reported to our infectious diseases control unit. Most of those injured were women. 58.4% of the events occurred in the vicinity of the patient. The source of exposure was known in 60% of the cases. 73.8% of those injured had already been immunized against hepatitis B. The departments in which most exposures occurred were the operating theater (12.5%), medical departments A (10.6%) and B (9.6%), and the emergency department (7.7%). Nurses were at highest risk, constituting 47% of those injured.

Our recommendations are that a continuous teaching program be established for the high risk groups; that HCW be urged to report every event of exposure; and to encourage HCW to undergo active immunization against hepatitis B.

Colonic angiodysplasia is one of the most frequent causes of recurrent lower gastrointestinal tract bleeding, mainly in the elderly. In 50% of patients multiple angiodysplastic lesions were reported when they were the cause of rectal bleeding. Bleeding from angiodysplasia is more severe and less responsive to treatment in those with coagulation disorders. A 74-year-old woman with an artificial mitral valve who was treated with coumadine is reported. A few years after operation she began to develop severe recurrent rectal bleeding because of multiple angiodysplastic lesions along the right colon, proven by colonoscopy. She was frequently hospitalized for blood transfusions; endoscopic treatment was not feasible and the surgical risk of colectomy was very high. Treatwith estrogen and progesterone significantly decreased recurrent episodes of bleeding.

Trisomy 18 is a chromosomal disorder giving multiple anomalies. Its frequency depends on maternal age. We report a 28-year-old woman in her first pregnancy, who underwent first trimester scanning for screening. Due to increased nuchal translucency and exomphalos, chorionic villous sampling was performed. Cytogenetic diagnosis was trisomy 18 and termination of pregnancy was carried out immediately.

80 Israeli family physicians (51.25% men and 48.75% women) participated in a telephone survey concerning attitudes, practices and experience with alternative medicine. 23.75% reported practicing 1 or more alternative techniques, most commonly acupuncture28%) and hypnotherapy (24%). 55% had referred at least 1 patient to an alternative practitioner during the preceding month. Physicians who studied in Israel or Western countries referred more patients than graduates of medical schools of Eastern Europe. Specialists referred patients more often than residents. The most common reason for referral was back pain.

Gastric leiomyosarcoma (GLMS) is a malignant, smooth muscle neoplasm accounting for not more than 0.45%-3.5% of primary gastric malignancies and 17%-20% of all smooth muscle tumors of the stomach. A well-chavariant has been variously referred to as leiomyoblastoma and epithelioid leiomyosarcoma. Because of the rarity of GLMS, few authors have tried to correlate clinical presentation, pathological findings, and treatment. There is no uniform therapeutic approach for leiomyosarcoma of the stomach and reported survival rates vary widely. We present a 56-year-old man whom we treated for this condition.

Brucellosis in Pregnancy

Brucellosis is rare in pregnancy. Recently, an increase in the incidence of this disease has been observed in our area. We present 7 cases of brucellosis in pregnancy and review the literature on the effects of brucellosis on the outcome of pregnancy. Brucellosis is rare in the Middle East and Africa and the most common source of infection is unpasteurized milk products. Brucella is a coccobacillus, gram-negative bacterium, whose hosts are mostly animals.

There is controversy about the relationship between brucellosis and the outcome of pregnancy. There is some evidence that there is a higher rate of complications such as abortion, premature rupture of membranes and preterm delivery in infected animals. Reasons for this difference in the impact of brucella in animals and man include the absence of the carbohydrate erythritol in the human placenta, which appears to be a preferential medium and growth factor for brucella in the placentas of animals.

There is uncertainty regarding effects of brucella in early pregnancy and no evidence of its transplacental passage in later pregnancy, causing adverse obstetrical outcome, although recently there has been a single report of Brucella abortus (biotype 2). 
We present 7 cases of brucellosis in pregnant women found between 1977-1988. Its incidence among the women who delivered here is 0.007% (7/92,768 deliveries). Our first case was complicated by preterm premature rupture of membranes and preterm delivery in the 20th week of gestation. In 2 other cases there was preterm delivery with 1 developing clinical chorioamnionitis. The 4 remaining women delivered at term, although 1 had preterm premature rupture of membranes and intra-uterine growth retardation, and 2 had postpartum endometritis.

Interest in, and use of alternative medicine has increased in the past few years in Israel. Still, little is known about the extent to which it is utilized, the more common treatments, patterns of use, and its influence on the conventional primary care system. We surveyed a kibbutz community to determine prevalence and patterns of use of alternative medicine and satisfaction with the outcome. The entire kibbutz population was asked to fill out a questionnaire (parents answered for their children). They were questioned as to their use of alternative medicine in the previous 5 years, types and dates of treatment, duration of treatment, and whether it had helped.

Of 1044 subjects, 830 responded (79.5%). 16.4% had used alternative medicine at least once in the previous 5 years. Of these, more than a 1/4 were treated by 2 or more types of alternative therapy. About 2/3 of those responding were women. Most had muscle-skeletal (36%), upper respiratory and/or atopic problems (19.3%). The most common treatments were homeopathy (31%) and acupuncture (20%). In approximately 2/3, the treatment was considered helpful, and either solved the problems or gave long-lasting improvement. 70% of those who used alternative medicine were treated within the previous 15 months and about 40% within the previous 3 months. The use of alternative medicine is increasing and it is now includein standard medical services. Most of those who used alternative therapy felt is hadhelped.

Acute appendicitis is the most common surgical problem in pregnancy, when it is difficult to diagnose early because of the physiological changes of pregnancy. We studied the problem in the Negev population and present the main issues in diagnosis and management. Between 1988-96, 26 women were operated on for acute appendicitis during pregnancy (1/3297 deliveries), 3 by laparoscopy. In 13 there was a histopathological confirmation of the diagnosis. Clinical diagnosis was more accurate in the first trimester of pregnancy than in the second or third (p=0.073). Premature delivery rate was higher in both confirmed and unconfirmed acute appendicitis than in other pregnancies (p<0.00001), but without significant differences between the 2 groups with appendicitis. Other indexes of maternal and perinatal morbidity did not differ either.

The relationship between parturients' sociodemographic characteristics and the tendency of the medical staff to offer and of the parturients to accept intrapartum epidural analgesia, was investigated. 97 Jewish parturients were interviewed during January 1996. Multiple logistic regression analysis was used to evaluate the statistical significance of the results. 10 parturients (10.3%) asked for intrapartum epidural analgesia, and while 46 (47.4%) were offered it, only 22 (22.7%) accepted. Epidural analgesia was mostly offered to, and accepted by: low birth-order parturients (1st-3rd delivery), those belonging to the upper middle class, and to parturients with higher compliance with prenatal diagnostic tests. There was no significant association between the tendency of the medical staff to offer epidural analgesia to secular as compared to traditional parturients.

We conclude that the use of intrapartum epidural analgesia is related to various maternal sociodemographic characteristics. If the low compliance with epidural analgesia is related to prejudice and unfounded fears, we recommend that the benefits of this type of analgesia be explained before birth in the antenatal clinics.

Pulmonary embolism is a common event in hospitalized patients. In some cases it presents with hemodynamic collapse, indicating massive obliteration of the pulmonary vasculature and has a very grim prognosis; 2/3 of such patients die within 2 hours of onset of symptoms. We describe our experience in 13 patients with massive pulmonary embolism. An aggressive diagnostic and therapeutic approach, utilizing sophisticated imaging techniques, thrombolytic therapy and surgery, led to the survival of 8 of the patients. Our experience supports an aggressive approach in these seriously ill patients.
