זה כשני עשורים מושקע מאמץ רב בפיתוח תכשירים סינתטיים המעכבים את פעילות ההורמון פרוגסטרון. מראשית פיתוחם עוררו תכשירים אלה מחלוקת מאחר ושימושם הראשון היה לצורך הפסקת הריון בשלביו המוקדמים. מעכבי הפרוגסטרון הפכו את תהליך הפסקת ההריון לזמין יותר תוך שמירה על פרטיות מרבית ונוצר חשש שמא התהליך יהפוך לבלתי מבוקר וייעשה שימוש לרעה בתכשירים אלה.

מיפפריסטון, המכונה גם RU 486 (Romainville, France, Roussel-Uclaf) הוא סטרואיד סינתטי בעל תכונות אנטי פרוגסטטיביות ואנטי גלוקוקוטיקואידיות. תכשיר זה יוצר לראשונה ב-1981 ומאז נעשה בו שימוש בתחומים שונים בגינקולוגיה ובמיילדות. מלבד יתרונותיו בהשראת הפלה, מיפפריסטון נמצא יעיל גם בדיכוי מחלת רירית הרחם (endometriosis), בהקטנת שרירנים ברחם, וכאמצעי למניעת הריון. מיפפריסטון מסייע גם בהבשלת צוואר הרחם ובהשראת לידה בשליש השני והשלישי להריון.

בסקירה זו מובא מיגוון האפשרויות הטיפוליות הכלולות בטיפול במיפפריסטון בתחום הפוריות, הגינקולוגיה והמיילדות. לאחרונה, הותר הטיפול במיפפריסטון במישלב עם פרוסטגלאנדין מיזופרוסטול על ידי משרד הבריאות לצורך הפסקת הריון ש לעד גיל 49 ימים. לאור זאת, עיקר הדגש בסקירה יהיה על הטיפול במיפפריסטון בהוריה זו.

טיפולי השראת ביוץ באמצעות גונאדוטרופינים מלאכותיים הביאו למהפכה של ממש בטיפולי הפוריות בשנים האחרונות, בכך שהעלו בהרבה את הסיכוי להרות, בעיקר בנשים עם הפרעות בביוץ, אך גם בנשים הלוקות באי-פוריות מגורמים אחרים, כגון עקרות בלתי מוסברת או עקרות הגבר. בנוסף מהווים הגונאדוטרופינים המלאכותיים מרכיב הכרחי בטיפולי ההפריה החוץ-גופית. אחד הסיבוכים היאטרוגנים הקשים של טיפולי השראת ביוץ בכלל ובגונאדוטרופינים בפרט הוא תיסמונת גריית-היתר של השחלות (ovarian hyperstimulation syndrome). תיסמונת זאת, על אף היותה נדירה, גורמת למירב התחלואה והתמותה הקשורות בטיפולי פוריות. התיסמונת מתבטאת בהגדלת השחלות, בחדירות-יתר של נימיות הדם עם דליפת נוזל למדור השלישי ובריכוז-יתר של הדם (hemoconcentration).

Streptococcus pneumoniae is an important cause of pediatric morbidity and its main reservoir is the nasopharynx, from which it can disseminate and cause invasive disease. From November 1997 through March 1998, nasopharyngeal carriage of S. pneumoniae was evaluated in 250 children under the age of 36 months: 123 Jews and 127 Bedouins with acute respiratory disease and in 980 healthy control children (852 Jews and 128 Bedouins).

Carriage rate was higher among sick children. Among Jewish children it was 57% and 35% of sick and healthy children respectively (p<0.01), and among Bedouin children it figured as 80% and 67% respectively (p=0.01). The difference in carriage rate was most prominent in infants under the age of 5 months: among Jewish children it was 60% and 27% of sick and healthy children respectively (p<0.001) and among Bedouins it was 82% and 65% respectively (p=0.05).

Higher carriage rate of penicillin resistant pneumococci (PRP) was also detected in sick children, with no relation to antibiotic treatment in the month prior to sampling. In Jewish children PRP was detected in 12%, 28% (p<0.001) and 36% (p<0.001) of healthy children, sick children with previous antibiotic treatment and sick children with no treatment, respectively.

The seroypes included in the newly developed 7-valent conjugate vaccine: 4, 6B, 9V, 14, 18C, 19F, 23F, that are highly pathogenic and often antibiotic resistant contributed 74% of isolates in sick Jewish children who had previous antibiotic treatment and 39% of isolates in healthy children (p<0.001). In Bedouin children vaccine types carriers rate among the sick children was not higher than in healthy children.

Acute respiratory disease increases the risk of pneumococcal carriage in general and carriage of resistant pneumococci in particular. Previous antibiotic treatment increases the risk of carring one of the pathogenic serotypes included in the 7-valent vaccine. The impact of disease is most prominent in infants under 5 months, since they are usually less exposed to S. pneumoniae carriers than older children.

Since the increase in carriage rate during illness is mostly due to the serotypes included in the newly developed conjugate vaccine, future immunization programme may decrease not only morbidity rate but also nasopharyngeal carriage rate of pneumococci in general and of antibiotic-resistant pneumococci in particular.

נפילות מהוות את אחת מבעיות הבריאות הקשות והשכיחות ביותר בקרב קשישים. נפילות נישנות בקרב קשישים מהוות סימן לתשישות, הפרעות בתנועה ומחלות כרוניות וחדות. נפילות כשלעצמן עלולות להחמיר קשיים בתיפקוד בקשיש כתוצאה מפציעות, הגבלות פעילות, פחד מנפילות ואיבוד תנועתיות ועצמיות, תופעה זו היא הגורם השכיח ביותר לפציעות בלתי מכוונות ולשברים בקרב קשישים.

נפילה מוגדרת כאירוע שבעיקבותיו האדם מוצא עצמו באופן לא מכוון על מישטח אחר, הנמצא נמוך ממקום הימצאו הקודם. נפילות המתרחשות עקב הפעלת כוח חיצוני רב (לדוגמה, תאונת דרכים), פעילות ספורטיבית או תקיפה, אינן נכללות בדרך כלל במסגרת האמורה. הגורמים וגורמי הסיכון לפנילות אלה בדרך כלל שונים ומהווים נושא נפרד.

יותר ויותר מתבהר הצורך לאבחן ולטפל בחוסר הביוץ. אי-הפוריות היא רק תוצאה אחת, קביעת האבחנה וטיפול בתאם יכולים למנוע תופעות שליליות נוספות לבריאות האשה. תוצאות של חוסר ביוץ כוללות ירידה בצפיפות העצם, ירידה בחימוד (ליבידו), תופעות בלתי רצויות בעור ובשיער, שיגשוג בלתי מבוקר של רירית הרחם (endometrium), מצב קרדיוואסקולרי מעורער ושינויים פסיכולוגיים ופסיכיאטריים. התוצאות הסוציאליות והפסיכוסוציאליות של חוסר הביוץ לא תמיד בתודעתנו, למרות חשיבותן הרבה. על כן, כדי לייעץ נכון למטופלת, דרושה אבחנה מדויקת, ככל האפשר.

המושג הבסיסי להבנת הפתוגנזה של הפרעות ביוץ קשור בהבנת העובדה, שהפרשה פעימתית מתאימה של GnRH (Gonadotropin Releasing Hormone) מההיפותאלאמוס במוח קובעת את מועד הביוץ והווסת. פעימות של GnRH מהירות או איטיות מדי יגרמו לחוסר ביוץ או להרס הגופיף הצהוב השחלתי טרם זמנו...

Spina bifida and anencephaly are the most common, serious malformations in neural tube defects (NTD). Randomized trials in the last 2 decades have demonstrated that folic acid, 0.4 mg/d, reduces the incidence of NTD by more than 50%. We investigated the use of folic acid and multivitamins containing folic acid in childbearing women.

Of 221 women interviewed, 67 (30%) regularly took pills containing 0.4 mg folic acid. Women with higher educational levels were more likely to take multivitamins with folic acid than were the less educated (p=0.05). Of the women who took folic acid, only 5 (7.5%) used separate folic acid tablets, before and during their pregnancy. The rest used multivitamins containing folic acid. The 5 women who took folic acid separately were college-educated and nonreligious, and they took multivitamins in addition (p>0.05).

Of the women interviewed, 58 (26.2%) were Bedouin of the Negev. 24 (41.4%) of them took pills containing folic acid on a regular basis. This percentage is higher than that in the Jewish women in the study who took folic acid for prevention of NTD (17%; p=0.038).

Most of the women took folic acid after the first trimester. Only a minority took daily periconceptional folic acid. Multivitamins containing 0.4 mg of folic acid were more popular than folic acid tablets alone. This study emphasizes the need for continuing efforts to increase consumption of folic acid and awareness of its benefits among women of childbearing age.

Pneumomediastinum Following Drug Abuse

Medical Division, Hadassah Hospital, Ein Kerem, Jerusalem

Pneumomediastinum is termed spontaneous when not associated with trauma or other identifiable pathological process. There are several reports of pneumomediastinum following narcotic drug inhalation or smoking while applying positive pressure. We describe a 37-year-old male drug addict, hospitalized after having being found unconscious with shortness of breath. CT scan demonstrated bilateral pneumonia with pneumomediastinum. After a day of mechanical ventilation he gradually recovered and the mediastinal air disappeared.

Pneumomediastinum may occur in addicts but usually has no dangerous clinical consequences. If there is respiratory deterioration another cause should be sought.

Juridical and Halachic Aspects of Postmortem Sperm Procurement

Institute of Halachic and Ethical Aspects of Medicine, Ramat Gan

The ability to fertilize human ova with sperm retrieved soon after death has been utilized in Israel and in other countries. However, postmortem sperm procurement (PMSP) has significant Halachic, juridical and ethical implications with regard to both the action of sperm and its implications for mother and offspring. In specific situations, and with reliable supervision aimed at preventing sperm interchange, Halacha may allow the procedure, while the juridical approach in such a situation is not as yet well established.

As for Halacha, even if a son is born, the widowed mother will still be obligated by the Halacha of yibum (marrying the deceased husband's brother). The child's rights as heir, aspects of implications for its future life, or even social aspects of PMSP, all are factors to be seriously considered before PMSP is performed, without bias by temporary emotions. Thus, PMSP should be reserved for only very special circumstances, and only after consultation with the appropriate medical, Halachic, juridical and ethical experts.

Division of Nursing and School of Nursing, Hadassah Medical Center, Jerusalem

350 patients attending 11 large out-patient clinics completed questionnaires evaluating attitudes to, and experience with complementary medicine. 129 (36%) respondents reported using complementary medicine. 14% of them used complementary medicine for the current medical problem for which they were attending the clinic.

Pain was the most common medical problem for which complementary medicine was used, followed by respiratory problems and cancer. Common therapeutic modalities used were acupuncture, homeopathy, nutrition and herbal medicine.

Women, the secular as opposed to the religious, and those with higher education were more apt to use complementary medicine. No differences were found in age, national origin, length of living in Israel, and diet (vegetarian, natural foods or regular diet) between those who used complementary medicine and those who did not. No relationship was found between the use of complementary medicine and perceived poor health status, locus of control, or satisfaction with the doctor-patient relationship.

Family Medicine Dept., Kupat Holim Klalit Health Services, Western Galilee District; Medical Education Unit, Bruce Rappaport Faculty of Medicine, Technion Institute of Technology; and Urology, Dept., Bnei-Zion Medical Center, Haifa

Physicians are frequently required to break bad news to their patients. Previous research has shown that inconvenience, incompetence, and difficulty in dealing with patients' feelings are the main complaints expressed by physicians after such an encounter. Current educational programs dealing with breaking bad news are usually short, given in lecture format, and are inadequate in addressing essential issues such as knowledge, personal beliefs and attitudes, and previous personal experiences of physicians in such situations.

In the past 8 years our Dept. of Family Medicine has implemented a course in breaking bad news that addresses these issues. A senior family practitioner and a medical social worker conduct 14 sessions of discussions and role-playing for small groups of residents and primary care physicians. The program is based on: theory dealing with methods of managing stress and crisis intervention, clarifying personal attitudes, discussions of previous personal encounters of the participants, various modalities of communication, methods of addressing patients' feelings and emotions, and coping with the emotions of the one breaking the bad news.

On a 1-5 Likert scale questionnaire the course received an overall score of 4.47 (SD 0.51). Participants noted that they gained relevant communication skills for future patient encounters. A reliable examination of practitioners' competence in breaking bad news is mandatory in order to assess the efficiency of such courses.

Our armamentarium for the treatment of erectile dysfunction has recently been expanded by addition of Viagra and the MUSE. However, their long-term results are still unknown. The insertion of a penile prosthesis is invasive, expensive, and irreversible, but under optimal condition provides an acceptable, definitive solution for erectile dysfunction. We evaluated our long-term results with penile prosthesis insertion (PPI).

From 1987-1998, 57 patients underwent PPI in our department. Mean age was 55 years and the common causes of erectile dysfunction were atherosclerotic disease (23), radical pelvic surgery (15), and diabetes mellitus (14). Semirigid prostheses were inserted in 12 and inflatable prostheses in 45, including 42 single-component and 3 multi-component prostheses.

Recently we interviewed these patients by telephone, using a standard questionnaire. Those not satisfied with the surgical results (83% of the living patients) were examined in our clinic. Mean follow-up was 53 months. In 37 (84%) the prosthesis was mechanically functional (rates after 1, 5 and 10 years were 87.8%, 80%, and 75%, respectively). In only 2 (2.5%) had serious complications led to prosthesis removal.

All mechanical failures had occurred in those with inflatable prostheses after a mean of 48.5 months (range 4-113). At the time of the survey 68% were sexually active and 64% were satisfied with the surgical result. We conclude that PPI is safe treatment for erectile dysfunction. Although the rate of mechanically functioning prostheses decreases with time, modern multi-component prostheses may lead to better mechanical results.

Total laryngectomy due to malignant laryngeal tumors is followed by loss of speaking ability. Voice restoration in laryngectomized patients is the main target in their rehabilitation. Until the late 70's, esophageal speech was considered the most effective rehabilitation method. In 1980 Singer and Blom introduced a prosthesis for tracheoesophageal speech which has been gaining popularity. Tracheoesophageal puncture (TEP) can be performed either at the time of total laryngectomy, or later.

30 of our patients underwent TEP between 1991 and 1999, 15 at the time of total laryngectomy and 15 as a delayed secondary procedure. Mean follow-up was 36 months (range 6 months to 8 years) during which all regained speaking ability.

Over the long range, speech rehabilitation with the prosthesis was successful in 24 (80%). In only 1 in the primary TEP group did treatment fail, as the prosthesis had to be removed due to local recurrence of the tumor. Long range failure in 5/15 patients after secondary TEP stemmed from difficulties some patients had in handling the prosthesis and from psychological difficulties in adapting to the new speech device. Complications were mostly minor and occurred mainly in the secondary TEP group.

TEP performed at the time of total laryngectomy, or later as a secondary procedure, is effective for speech rehabilitation after laryngectomy.

Glucosamine Sulfate and Chondroitin Sulfates for Degenerative Joint Disease

Osteoarthritis results from progressive catabolic loss of cartilage proteoglycans due to imbalance between synthesis and degradation. The availability of glucosamine, an intermediate in mucopolysaccharide synthesis, can be rate-limiting for proteoglycan production in cartilage tissue culture.

57 patients suffering from osteoarthritis of the knee were randomized into a group treated for 4 weeks with daily IV glucosamine sulfate (GS) together with 800 mg chondroitin sulfate, and a placebo group. Knee pain at rest, on movement and on palpation, as well as range of knee motion were then recorded.

In the GS group, there was significant reduction of clinical symptoms (p<0.01), but no significant reduction in the placebo group. Physicians' assessment of tenderness and range of motion were significantly in favor of the GS group (p<0.01). In those treated with glycosamine there were no adverse reactions and no changes in laboratory blood tests.

37 candidates for epilepsy surgery underwent the intra-carotid amytal procedure (IAP; also known as the Wada test) to determine hemispheric speech dominance and memory capacity. 31 demonstrated left hemisphere speech dominance, 2 showed evidence for bilateral language and 4 demonstrated right hemispheric language dominance.

Our study supports a correlational relationship between handedness, lesion laterality and age of onset of seizures, as reported in earlier studies. Left-handed patients with a left hemisphere lesion whose seizures began to an early age had a strong tendency for reversed language dominance.

Asymmetry of at least 20% in performing the memory test was taken as the cutoff score for demonstrating laterality of lesions. The asymmetry score correctly predicted laterality of lesions in all 28 patients; 6 did not have asymmetry scores and 3 were examined for language only. None of the patients who successfully passed the Wada memory test had any significant postsurgical memory deficits; 1 had transient reduction in verbal memory and 4 who did not pass the test were not operated on for this reason.

Our results demonstrate the importance of the Wada test in determining cerebral speech dominance, in predicting post-surgical amnesia, and support its usefulness in predicting laterality of seizure focus in candidates for temporal lobectomy.
