רקע: צריכה מופרזת של הורמוני תריס ממקור חיצוני עלולה להתבטא בהפרעת יתר פעילות של בלוטת התריס משמעותית ולפגוע בבריאות האדם. למרות זאת, מספר הולך וגדל של אנשים צורך מוצרים 'מעבר לדלפק' המכילים, בין היתר, טרי-יודו-תירונין  (T3) ותירוקסין (T4).

מפרשת החולה: אנו מדווחים על פרשת חולה שצרך טבליות המכילות ליותירונין ובעקבות כך לקה בפעילות יתר של בלוטת התריס כתוצאה מחשיפה חיצונית ל- 3T (יתר פעילות של בלוטת התריס מוּאץ-3T). המטופל היה בעל מדדי השמנה (BMI של 40 ק"ג/מ²) ללא מחלה של בלוטת התריס הציג סימני פעילות יתר של בלוטת התריס שהיו אופייניים (כללו אוּץ לֵב רחב ומורכב, חום גוף מוגבר, כאבים בבית החזה וקצב לב מוּאץ) שאושררו בבדיקת תפקודי תריס: תירוטרופין (TSH) ו- 4T חופשי נמוכים ו- 3T חופשי (FT3) מוגבר. טרם האשפוז החולה לא נחשף לחומרי ניגוד מכילי יוד או נטל תרופה המכילה יוד. התברר כי בחמשת הימים שקדמו לאשפוז, הוא נטל טבליות ליותירונין (135 מק"ג/טבליה) בהתאם להצעת אדם שהציג עצמו כתזונאי. הטבליות שווקו לו באופן כוזב כתוסף תזונה "להורדת משקל". הוא הונחה להפסיק את נטילת טבליות הליותירונין והוחל טיפול תרופתי באמיודארון (טרם קבלת תוצאות FT3) לצד כולסטיראמין. בתום שלושה ימי אשפוז ביחידה לטיפול נמרץ, המטופל התייצב עם קצב לב תקין וירידה ניכרת ב- 3T חופשי. בתום חקירה, משרד הבריאות פרסם באתרו אזהרה לציבור להימנע מצריכת טבליות אלו. במעקב בקהילה, קצב הלב של המטופל נבדק בהתאם לדיווחיו ותפקוד חדר לב שמאלי נמצא ירוּד – גבולי. במהלך כל ארבע השנים משחרורו ממוסדנו, רמות TSH שנבדקו נמצאו תקינות.

סיכום: בפרשת החולה במאמרנו הנוכחי, דיווחנו על יתר פעילות של בלוטת התריס לצד נזק מתמשך ללב על רקע צריכת כמות מופרזת של ליותירונין שסופק למטופל על ידי גורם בלתי מורשה. מתן ליותירונין ונטילתו בוצעו מבלי להסתמך על בדיקה רפואית ולמרות שהמטופל לא סבל מתת-תריסיות. העלייה בביקוש למוצרים "להורדת משקל" 'מעבר לדלפק', היעדר אכיפה יעילה במרשתת, אופן הצגת מוצרים אלה והאפשרות של מי שאינם מורשים לכך לשווקם ולספקם, מדגישים את הצורך באַסְדָרָה (רגולציה) של הנושא בהקדם.

Bronchial asthma in the pediatric age group has become prevalent recently. Many children who suffer from asthma arrive at the emergency room (ER) with exacerbations which did not respond to medical treatment at home.

Between July and December 1997, 136 children 8 months to 14 years of age (61% below 3 years), were studied in our pediatric ER. Investigation included physical examination and pulse oximetry, which were used as guidelines for scoring the children on arrival and post-treatment. Spirometry was done in those who could cooperate. For each patient a detailed questionnaire about medical and sociodemographic factors was filled.

Primary pediatricians used mainly beta-agonist and corticosteroid inhalators, while pediatric pulmonologists used mainly inhaled steroids. There was no relationship between severity of attack on arrival at the ER, mode of treatment and speed of recovery in the ER. More children treated by a general pediatrician more were admitted to hospital. Low parental education and paternal smoking were risk factors for recurrent hospital admissions.

Our results indicate that parents must be educated to stop smoking, especially those with asthmatic children, and primary pediatricians should be updated with regard to proper treatment and follow-up of asthma.

Violence in the Emergency Department

There is an international epidemic of violence in the emergency department (ED) which threatens medical staff daily. The problem is underestimated in Israel and there are as yet no regulations of the Ministry of Health and the Bureau of Security and Safety that deal with the problem.

At the beginning of 1997 we conducted a retrospective survey to estimate the extent of this problem and to define its causes and the various options for management. An anony-mous questionnaire was given to all permanent workers of our ED: physicians, nurses and reception clerks, as well as physicians who worked in the ED during evening and night shifts at least twice a week.

74% of (questionnaire) responders experienced violent events, most of them 5 or more times during the previous 2 years. Violence was experienced by 90% of nurses, 70% of physicians and 64% of clerks. The main reason for violence was prolonged waiting in the ED. Other causes were dissatisfaction with treatment, refusal to leave the ED, and language that displeased the patient.

Most violent patients were middle-aged men, of whom alcohol and drug users were only a small proportion. Most victims of physical violence called hospital security personnel, but only a third of the victims of verbal violence pressed charges. Half of the staff who were physically attacked called the police and most pressed charges. Only 2 attackers were convicted; charges were dropped against 3 because of "lack of public concern." We were unable to ascertain the results of the other charges. Most victims of violence didn't press charges because of fear resulting from threats of the patient and/or family.

The violent patient was usually characterized by responders as a middle-aged man, sober, of low socioeconomic level, impatient, with a bad previous hospital experience, dissatisfied with treatment and who insisted on being admitted to hospital.

Suggestions for violence management by questionnaire- responders included 24-hour police protection and a training program in violence management for hospital security and medical staff.

Investigating Chest Pain: is there a Gender Bias?

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.

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.
