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 At the end of the 60's an outbreak of pulmonary hypertension was associated with the drug aminorex, and it was soon withdrawn from the market. 30 years later it became clear that new-generation anorectic drugs (fenfluramine, dexfenfluramine, phentermine), which were being used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.

Depts. of Medicine A and Hematology, Rambam Medical Center and Technion School of Medicine, Haifa

Thrombotic thrombocytopenic purpura (TTP) is characterized by 5 findings: fever, neurological abnormalities, microangiopathic hemolytic anemia, severe thrombocytopenia and renal abnormalities. The syndrome occurs more often in females, usually in their 20's. Since the beginning of the current AIDS epidemic, there have been reports of an association between HIV infection and TTP. We describe a 31-year-old man with HIV who developed TTP, and review the literature.

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.

Aphthous Stomatitis as a First Manifestation of Crohn's Disease in a Child

Y. Gold, S. Reif

Dana Children's Hospital, Tel Aviv Medical Center

The incidence of Crohn's disease has risen dramatically over the past few years. The peak age of onset is in late adolescence, but it rarely occurs in the first few years of life. We describe a 5-year-old boy with recurrent bouts of fever, aphthous stomatitis, and anemia which did not respond to routine antibiotic therapy. It was only after a few months, when the characteristic symptoms of inflammatory bowel disease (IBD): abdominal pain and diarrhea appeared, that the diagnosis of Crohn's disease was made.

This case illustrates the difficulty in diagnosing IBD in young children. The presenting symptoms of IBD in children are often nonspecific and extra-intestinal. There is usually a low index of suspicion by the physician as to the possibility of IBD in a young child.

During routine emergency room work penetration by foreign objects is frequently encountered, some of which may be very irregular in shape. These may cause further damage if inappropriately removed. It is important to perform a proper X-ray survey.

Diagnosis of Hyperprolactinemia: Determination at Rest Rules Out Stress-Induction

Endocrine Institute, HaEmek Medical Center, Afula and Rappaport Faculty of Medicine, The Technion, Haifa

We present 3 women who were referred for evaluation of stress-related mild-to-moderate hyperprolactinemia. This frequent finding may mistakenly be considered a clinical problem, and lead to inappropriate investigation and therapy. We emphasize the importance of serial blood sampling for prolactin determination. We collected blood samples repeatedly under resting conditions from an indwelling venous brachial catheter, every 30 minutes for a total of 6 samples. All 3 patients had normal prolactin levels 30-60 minutes after starting the test. Neither further investigation nor medical therapy were needed and these anxious patients were reassured that their hyperprolactinemia was factitious.

The Surgeon and the Emperor: a Humanitarian on the Battlefield

Dept. of Neurosurgery, Rambam (Maimonides) Medical Center; B. Rappaport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa

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.

Art Therapy for Hospitalized Children (Inspired by Elizabeth Kuebler-Ross's Approach)

Edna Pinchover*

Pediatric Wards School, Hadassah Hospital (Ein Karem and Mt. Scopus), Jerusalem

This paper presents a combined strategy for coping with the emotional condition of hospitalized children, and reports the results of its implementation in pediatric wards. The strategy combines art therapy methods with the spiritual-psychological approach developed by Elizabeth Kuebler-Ross. Art therapy uses art for therapeutic and diagnostic purposes; in this study it was employed to encourage the child-patients to express their feelings, and lead them to processes of understanding of and adjustment to their conditions. Kuebler-Ross' methods, known for dealing with difficult emotional situations at the bedside of the seriously ill, were enlisted to build a relationship of trust and respect between patient and therapist.

The population dealt with consisted of children (age 3-13) injured in road accidents, and cardiac and oncological cases. 7 case studies are brought to demonstrate the integrated therapeutic process. The process starts from the child-patient's artwork, which allows the therapist better insight into emotional conditions and to relate closely to issues brought up by the work. Through conversation with the therapist in an atmosphere of empathy and honest consideration, the patient becomes aware of her/his reactions, behavior, intentions and ambitions.

The belief underlying this study is that the patient derives from these contacts new abilities which moderate anxieties and strengthen healthy energies. Better collaboration and sounder ways of coping with intrusive medical treatment, as well as more trust and hope seem to emerge from the relationships created by these contacts.

Rupture of the pectoralis major muscle in an athlete is rare, but is said to be common in weight lifters. The muscle usually ruptures at the musculotendinous junction during forceful contraction of the muscle in adduction, forward flexion and internal rotation of the arm. We describe an athlete who suffered such a major tear during a rugby game. It was treated surgically and after adequate rehabilitation, athletic activities were resumed.

Follicle-stimulating hormone (FSH) is considered to be the most important plasma hormone correlated with spermatogenesis. Elevated FSH plasma levels were shown to be associated with complete damage to testicular seminiferous tubule germinal epithelium. Recently, there have been conflicting reports with regard to the value of FSH plasma levels in predicting seminiferous tubule histology in the azoospermic patient and hence, as a guide for therapy in assisted reproduction using testicular sperm retrieval. The aim of this study was to evaluate whether FSH plasma levels can predict spermatogenic pattern in the testes of the azoospermic infertile patient. 69 infertile men with non-obstructive azoospermia and 18 with very severe oligospermia were studied. In all, plasma levels of testosterone, free testosterone, prolactin, luteinizing hormone and follicle-stimulating hormone were measured by enzyme immunoassay. In the azoospermic patients the seminiferous tubule spermatogenic pattern was determined in testicular aspirates obtained by multiple fine needle aspiration and categorized according to the most mature spermatogenic cell type in the aspirates: Sertoli cells only, spermatogenic maturation arrest or full spermatogenesis. There were no significant differences in plasma levels of any hormone measured except in very severely oligospermic and azoospermic patients. Both normal and elevated levels were detected in all, regardless of seminiferous tubule cytological pattern or plasma FSH in azoospermic patients. It is concluded that plasma levels of FSH can not be used as a predictive parameter, neither for the presence of spermatozoa nor for any other seminiferous tubule cytological pattern in azoospermic infertile men. They cannot serve as guides for selection of azoospermic men for trials of testicular sperm retrieval in assisted reproduction.

Orthopedics Dept., Soroka Medical Center, Beer Sheba

Vacuum phenomenon is well known in degenerative spinal disease in the elderly, but is seldom seen in other joints, especially in children. The phenomenon does not represent a pathological finding, and can be used for imaging of the articular facets, mainly in the hip and knee joints. We report a patient with this phenomenon in the hip joint.

Medical Dept B, Chaim Sheba Medical Center and Sackler Faculty of Medicine, Tel Aviv University

Impotence, a common problem especially among older men, can now be treated with Viagra, This oral pill, unlike previous approved treatments mostly involving local injections, does not directly cause penile erection, but increases response to sexual stimulation. It acts by enhancing the relaxant effects of nitric acid on smooth muscle, and thus increases blood flow to certain areas of the penis, leading to erection. It has been evaluated in many randomized trials and in all was more successful in inducing erection than placebos. The most common side-effects include headache, flushing and indigestion, but there have also been reports of fatalities.

We describe a 75-year-old man who had an acute myocardial infraction in the past and who had maturity-onset diabetes and hypertension. In the week prior to admission he had a cardiac scan following a few weeks of exacerbation of anginal pain for which he had been taking nitrites. He took a Viagra pill without prescription or medical advice and 2 hours later, during intercourse with his wife, developed audible respiratory distress and lost consciousness. His wife started cardiac massage but not mouth-to-mouth breathing. The emergency team found ventricular fibrillation and gave 5 electrical shocks and amines and atropine. He remained unconscious, but his pulse returned and he was hospitalized. He then had several generalized convulsions treated with IV valium. 20 minutes after admission there was asystole and all attempts at resuscitation failed.

Cardiovascular status must be considered prior to prescribing Viagra, and the associated risk evaluated.

Osteoid Osteoma of the Hand: a Rare Location

Nahum Rosenberg, Shalom Stahl

Dept. of Orthopedics A, and Hand Surgery Unit, Rambam Medical Center, Haifa

Osteoid osteoma is a benign bone tumor. It is rare in the hand where it may cause local swelling and pain. Marginal resection is almost always curative, without residual functional disability. Because it is rare in this location, osteoid osteoma is not usually considered in the differential diagnosis of painful lesions of the hand, which may delay treatment. Osteoid osteoma in the hand has characteristic clinical, roentgenologic and scintigraphic features. Early diagnosis of this lesion may be improved by recognition of these features. An algorithm for decision-making that may help is proposed. We describe our experience in 3 cases involving, respectively, the capitate bone, a proximal, and a distal phalanx, in which cases marginal resection was curative.

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.
