ההסתייעות בתהודה מגנטית (תה"מ)לדימות קדם-לידתי משלים לבדיקת-על שמע מתרחבת והולכת בשנים האחרונות, זאת הודות לפיתוח רצפי תהודה מגנטית מהירים. רצפים אלו מאפשרים השגת תמונות בדרגת הפרדה גבוהה של העובר במהלך עצירת נשימה אחת של האם, תוך מיזעור הארטיפקטים עקב תזוזת העובר.

במאמר זה מדווח על ניסיוננו בהסתייעות בתה"מ לאיבחון מומים עובריים והריוניים.

באוכלוסיית המחקר נכללו 39 הרות אשר עברו מיולי 1998 ועד יולי 2000 מספר כולל של 40 בדיקות תה"מ. ההוריה לביצוע כל הבדיקות היתה חשד למום עוברי או הריוני על-פי בדיקת על-שמע, בדיקות מעבדה או אנאמנזה משפחתית.

בשלושים-ואחת נשים (77.5%) נמצא מיתאם בין המימצאים בבדיקת העל-שמע למימצאים בבדיקת התה"מ, מהן ב-6 נשים (15%) תרמה בדיקת התה"מ מידע חדש חשוב. בעשרים ושש נשים (66.6%) נבדק המיתאם בין מימצאים טרום-לידתיים לבין מעקב קליני, דימות או בדיקה פתולוגית בתר-לידתית. בשתי נשים המימצאים הקליניים והדימות הבתר-לידתי לא תאמו את המימצאים הטרום-לידתיים שהודגמו בעל-שמע ובתה"מ.

תה"מ נחשבת בדיקה בטוחה במהלך ההריון, אם כי אין לכך הוכחות ברורות, מאחר שאין מסתייעים בבדיקה זו בקרינה מייננת. שיטה זו מדגימה היטב את האנטומיה והפתולוגיה של העובר, ואת המיבנים האימהיים, כדוגמת הרחם והשיליה, אמצעי דימות זה מסייע בנשים בהן עלה בבדיקת על-שמע חשד למום עוברי או הריוני, או במצבים בהם גורמים טכניים מגבילים את יעילותה של בדיקת העל-שמע. תה"מ סייעה להורים ורופאים להכריע באשר לגורל הריון שנחשד כבלתי תקין בזכות קבלת מידע משלים חשוב לבדיקת העל-שמע.

זיהום בנגיף הוואריצלה זוסטר (varicella zoster) בהריון הוא אירוע נדיר, ונחשב מאז ומעולם כבעל יכולת לגרום מומים בעובר, בעיקר במחצית הראשונה להריון. לזיהום בהריון יש גם השלכות הקשורות בתחלואה ותמותה אימהית. לכן, למרות שהזיהום נדיר, יש התייחסות רבה לכל אפשרות של זיהום מנגיף הוואריצלה זוסטר במהלך הריון. בסקירה זו תובא הספרות העדכנית בנושא אבעבועות רוח בהריון, תוך התייחסות לשכיחות, לאיבחון טרום-לידתי, לטיפול ולמניעה.

במאמר זה נדגיש, שבדיקת דם לקביעת המצב החיסוני לאבעבועות רוח מהווה שיטה מספקת על מנת לקבוע מי תקבל טיפול סביל בנוגדנים, ויש לדאוג למערך מתאים שבאמצעותו ניתן יהיה לבצע את הבדיקה במהירות. נוכח השיעור הגבוה של מחוסנות, ניתן בגישה זו למנוע את רוב המקרים של צורך במתן חיסון סביל, כמו גם סילוק מתח ודאגה מיותרים.

כעשרים שנה לאחר לידת יילוד ההפריה החוץ-גופית (הח"ג) (IVF–IN Vitro Fertilization) הראשון, נולדים ברחבי העולם כ-40,000 ילודים באופן זה מדי שנה. הריונות אלה שונים מהריונות "עצמוניים", בעיקר בשיעור גבוה יותר של הריונות מרובי-עוברים (המ"ע), לאחר החזרת יותר מעובר אחד לרחם. במרבית המדינות מדווח, כי שיעור המ"ע לאחר הח"ג נמדד כדי 40%-30%, בהשוואה לשיעור של 3%-2% באוכלוסייה כללית. שיטות ההפריה החדישות (ART- Assisted Reproductive Technology), בהן מתבצעת הח"ג והחזרת מספר עוברים לרחם (ET- Embryo Transfer), יחד עם שיטות חדישות להשראת ביוץ, נחשבים לגורם המוביל לעליית שיעור לידות מרובות עוברים – עליה דווח בעשורים האחרונים. מגמה זו מעוררת דאגה רבה, לנוכח ההשלכות הרפואיות החברתיות, הכלכליות והאתיות, מאחר שנשים הנושאות ברחמן שני עוברים או יותר, נמצאות בסיכון מוגבר לסיבוכי הריון ולידה ואף ליילודים צפויים שיעורי תחלואה או תמותה גדולים יותר – הן בטווח הקצר והן בטווח הארוך (כמו פגות קיצונית ו- cerebral palsy), בהשוואה להריונות יחיד. בסקירה זו, נציג את נושא החזרת העוברים ותוצאה אפשרית של המ"ע – על היבטיו השונים.

We report our preliminary experience of prenatal screening for Down's syndrome (DS) using nuchal translucency (NT) measurement combined with the serum biochemistry analysis of Free b-human chorionic gonadotropin (FbhCG) and pregnancy associated plasma protein A (PAPP-A) all measurement at 10-14 weeks of gestation.

Of the 358 parturient women which enrolled in the study, 9 cases were not included because of fetal anomalies or miscarriages. Thus the study group included 349 singleton pregnancies in which complete prenatal and infant follow-up was available.

Forty-four pregnant women were found to be screen positive (12.6%) and in 13 cases (27%) of them fetal chromosomal aneuploidies were diagnosed. Looking into the markers profile we found that the NT was a sensitive marker which was abnormally increased in all the fetal aneuploidies. Serum FbhCG was found to be a promising marker as well, being significantly elevated (2.26[0.86 multiple of the medians, MoM) in DS cases, and decreased (<0.5 MoM) in two cases of Edward's syndrome.

On the contrary, PAPP-A was found less sensitive, and its mean MoM values were not significantly different between DS versus euploid fetuses.

Our preliminary results support the promising success of DS screening using NT and FbhCG.

Cervical pregnancy is a rare but serious complication. The most frequent presenting symptom is vaginal bleeding, and is thus common in inevitable abortion. Examination reveals a dilated cervix containing products of conception derived from the emptied uterine cavity. The pathologic criteria are cervical glands opposite the placental site, attachment to and actual invasion of the cervix by the placenta, a portion of the placenta below the posterior reflection, and no fetal parts in the corpus uteri. Treatment ranges from hysterectomy to treatment with chemical agents, mostly methotrexate. We present a case of ectopic, cervical pregnancy with exaggerated placental site in the cervix.

Increased fetal muchal translucency (NT) thickness at 10-14 weeks of gestation may indicate underlying fetal chromosomal abnormalities, anatomical anomalies and genetic syndromes. Between January 1997 and May 1998, 1400 women 10-14 weeks pregnant underwent sonographic screening for detection of Down's syndrome (DS). Follow-up was complete in 1208 (86%).

Maternal age ranged from 17-44 years (mean 18.0). 87% were found by screening to have a higher risk (1:380) for DS diagnosed at birth. All these fetuses were karyotyped and 8 had chromosomal abnormalities. 2 fetuses with normal NT were diagnosed later as having DS, 1 by the mid-gestation triple test and 1 by amniocentesis because of advanced maternal age.

Thus sonographic screening identified 8 out of 10 fetuses found to have chromosomal abnormalities at birth. Neonates not karyotyped before birth had no traits at birth that justified chromosomal analysis. Results of this study suggest that NT measurement, combined with maternal age, is an effective 1st trimester screening method for DS in an unselected obstetric population.

Increased thickness of fetal nuchal translucency (TNT) measured at 10-14 weeks of gestation, may suggest underlying fetal chromosomal defects, structural abnormalities or genetic syndromes. We examined the relationship between increased TNT and pregnancy outcome, especially in fetuses with normal karyotypes.

1400 pregnant women underwent first trimester scanning and screening for chromosomal abnormalities and measurement of fetal TNT. 25 fetuses (2%) with increased TNT (>3 mm) were identified. 8 (30%) had an abnormal karyotype. Of these, 5 pregnancies were aborted, 3 ended in spontaneous abortions before karyotyping, and 2 were terminated, all before detailed cardiac scanning. There was a high association between increased TNT and karyotype abnormalities. The total incidence of favorable outcome in fetuses with normal chromosomal and cardiac features but enlarged TNT was 56%.

The development of laparoscopic surgery in gynecology and general surgery has greatly advanced over the past decade, and recently has been successfully performed in pregnancy. In the English literature we found that of the 518 cases reported (mean age 32 years) the most common was for cholecystectomy (45%), followed by operations on the adnexae (34%), appendectomy (15%) and others (6%). To these we add 3 cases of cholecystectomy and 1 of an adnexal tumor. Of all the reported cases, 33% were performed in the 1st trimester, 56% in the 2nd and 11% in the 3rd.

This review demonstrates a definite trend to laparoscopy in pregnancy. It appears to be safe when performed by experienced surgeons, but further studies addressing safety of laparoscopic surgery during pregnancy are needed to reach definitive conclusions.

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.

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.

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.

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.

Experience with Under-Water Birth

Underwater birth is now deemed an acceptable type of delivery. Safety is a recurring consideration, the main concern being that of drowning. But in reports of 19,000 underwater births no untoward events were noted. Also, need for pain relief and of intervention during labor were both reduced. The short term indicators of neonatal outcome were good. A recent review explains 5 different physiological factors which inhibit initiation of fetal breathing under warm water. Many studies have shown no increase in risk of infection of either mother or baby. We report our experience with 26 women, 23 of whom actually delivered in the pool with excellent results. We believe that birth under water is safe and beneficial if done properly for low-risk patients.
