התפיסה המקובלת היא, כי חיתוך דופן אלקטיבי אשר נעשה ללא הוריה רפואית הוא פעולה פסולה. בעשור האחרון למאה ה-20, הובעו דעות שחלקו על תפיסה זו והתעורר ויכוח לגבי מקומה של הלידה הלדנית במאה ה- 21. הוויכוח אשר זכה לתהודה תקשורתית רבה החל בבריטניה והתעורר אף בישראל, בה שיעור חיתוכי הדופן עולה בהתמדה. עפ"י הנתונים שנאספו ע"י יו"ר החוג לרפואה סב-לידתית והוצגו בכינוס השנתי האחרון (7 ביולי 2000), היה השיעור הממוצע של חיתוכי הדופן בשנת 1999 כדי 14.6% מכלל הלידות בישראל, פי שלושה מהשיעור בשנת 1977 (5.5%) ובשליש יותר לעומת השיעור חמש שנים קודם לכן (11.3%). בסקירה של בן-הרוש וחב' (בגיליון זה), נדונה השאלה של ניהול לידה פעיל בתקופתנו. לאור הוויכוח לגבי חיתוך-דופן עפ"י בקשת היולדת (cesarean section upon maternal request) נראית שאלה זו לכאורה ארכאית. לפיכך, בצד ניהול לידה פעיל, יש להכיר את הוויכוח לגבי אופייה של הלידה הלדנית במאה ה- 21.

Positron emission tomography (PET), when used with F-18 fluoro-deoxyglucose (FDG), contributes to the evaluation of patients with lung cancer. This technique of imaging detects active tumor tissue by showing increased radiopharmaceutical uptake by metabolically active cells.

Thus, PET assists in the early diagnosis of pulmonary malignancies that appear only as non-specific findings on CT-scan or chest X-ray. In addition, it is helpful in staging lung cancer before and after resection, chemotherapy or radiotherapy, or their combined use.

We performed 135 FDG-PET studies between July '97-April '99. and present our preliminary results with examples of the main indications for PET in lung cancer.

Prostatic cancer (PC) is second only to lung cancer as a cause of cancer mortality in men word-wide. In Israel it is the most common cause of cancer mortality in men, after lung cancer and colo-rectal cancer.

We screened, for the first time in Israel, for prostatic cancer using serum levels of PSA and a digital rectal examination (DRE). The purpose was not only to diagnose PC but also to increase public awareness of the condition.

300 men in the Haifa area who met statistical criteria for early diagnosis of PC participated. They filled a questionnaire regarding risk factors for PC (age, family history (FH) of prostatic and breast cancer, cigarette smoking, alcohol consumption, previous PSA sampling) and were examined. Those who had out-of-ragne, age-related PSA values, or a pathologic DRE underwent trans-rectal ultrasound (TRUS) examination and guided biopsy of the prostate. Those with a positive biopsy for PC underwent radical prostatectomy or radiation therapy.

41 (14.3%) had out-of-range, age-related PSA levels and 10 (3.5%) had a pathologic DRE. 39 (13.3%) underwent TRUS and biopsy and 6 (2.04%) had clinically significant PC, all early stages (Gleason 4-6).

Correlation between age and PSA has been proven statistically significant (p<0.05). Symptoms of urinary tract obstruction and nocturia were related to a high PSA (p=0.035 and 0.002, respectively). Those with PC had at least 1 symptom of urinary tract obstruction; 6 (15.3%) who underwent TRUS and biopsy and a FH of prostate cancer. However, no subject with a FH of PC had biopsy-proven cancer. Those with PC had PSA values from 4.9 to 31.8 ng/ml (9.6 median). Age-related PSA had a positive predictive value of 17.1%.

Results of our annual screening for early detection of PC using age-related PSA, and DRE are encouraging: cases detected were clinically significant and treatable. It would appear that screening for PC will result in decreasing the incidence of metastatic cancer and therefore mortality.

In some muscular dystrophies there is ocular involvement characterized by blepharoptosis and ophthalmoplegia. These conditions occur in chronic progressive external ophthalmoplegia, oculopharyngeal muscular dystrophy, mitochondrial myopathy, myotonic dystrophy, and ocular myasthenia, among others. Although they differ in their systemic clinical manifestations and in genetic inheritance, ocular involvement is common to all of them. Manifestations include bilateral progressive blepharoptosis with or without extraocular muscle malfunction.

During surgical repair of the ptotic eyelid, consideration must be given to eyeball movements, in addition to maximal eyelid elevation, and to avoiding overcorrection and consequent corneal overexposure, leading to dryness and visual impairment. With these muscular dystrophic disorders, resection of the levator muscle or blepharoplasty alone does not suffice. Follow-up shows that most patients need a secondary repair after a short while. Operative correction uses a frontalis sling for eyelid elevation and support.

A series of 8 patients with these diseases, operated on by various surgical techniques during the past 7 years, is presented.

Acrylate glues used in a childrens' day care unit to close small surgical wounds were compared. In 157 children, aged 12 weeks to 3.7 years, either Histoacryl or Dermabond was used (respectively, H: Ethicon Inc., Johnson & Johnson, NJ or D: Dermabond, Braun Surgical Gmbh, Melsungen, Germany). Operations were for inguinal hernia (110 cases), hydrocele (25), undescended testis (16), umbilical hernia (13) and funiculocele (3).

1 week after surgery the wounds were evaluated in terms of integrity of closure, redness or infection, need for antibiotics, wound granuloma, and parental satisfaction with instructions and actual method of wound caring. 3 months after surgery the wound/scar was reexamined.

The margins of the wounds were separated partially or completely in 8 of 85 in group H (9.4%) while in the D group, 2 wounds (2.4%) had partially opened (p<0.05). There were no differences between the glues with regard to wound infection or cosmetic results. Parental satisfaction was higher with D (96%) than H (82%) but the difference was not statistically significant.

It is convenient to use glue to close operative wounds in children after ambulatory surgery. The use of D significantly reduced wound ruptures compared to H. Long-term cosmetic results were similar.

Infection with Echovirus 11 is mostly asymptomatic, but it may cause a wide variety of clinical diseases, from gastroenteritis to serious diseases such as meningitis and myocarditis. In small infants, especially during the first days of life, echovirus infection may appear as a sepsis-like illness, and cause disseminated intravascular coagulopathy and shock.

We present 2 infants with severe echovirus 11 infections. A 3.5-month old died within 24 hours of shock and probably myocarditis. The other, 6-days old, presented with meningitis, hepatitis and disseminated intravascular coagulopathy. It recovered after treatment with intravenous immunoglobulin.

Echovirus 11 may cause life-threatening infections in small infants. Pediatricians should be alert to the special characteristics of this disease.

Results of reconstruction of residual alveolar bone defects in 52 patients operated between 1990-1998 were evaluated clinically and radiographically in a retrospective study.

Ages ranged between 9-37; 30 were males. The donor site of bone grafts in all was particulate cancellous marrow from the anterior iliac crest. 32 had unilateral clefts and 20 bilateral. Total cleft sites treated was 72.

Best results were achieved when bone grafting was carried out prior to the eruption of the canine tooth. The cleft space was closed and oro-nasal fistulas were eliminated in 42 (80%). Success rates in unilateral and bilateral cases were significantly different.

Acute lymphoblastic leukemia (ALL) is a malignant disease whose incidence is relatively low among adults, unlike in children. Adults with ALL have a lower rate of long-term disease-free survival. During the last 20 years, a German multicenter group has shown that their protocol have achieved good results in adult ALL.

We reviewed the medical records of 35 ALL patients, aged 19-63 years, whome we treated with these protocol (1988-1997). The remission rate was 94%. At a median follow-up of 46 months the 2-year overall survival was 54% and the disease-free survival was 94%. Although 2 patients died of bone marrow transplant complications, no death was directly associated with drug toxicity. The main grade 3 or 4 side effects (WHO classification) were neutropenia (91%), thrombocytopenia (71%) and anemia (71%).

With there protocols we achieved high overall and disease-free survival rates, especially in comparison with other reports. Despite the high rate of severe treatment toxicity, there were no fatalities directly related to treatment. These results emphasize the need to concentrate treatment of adult ALL patients in large medical centers with expertise in the use of the complicated treatment protocols required.

Patients with ischemic mitral insufficiency and poor left ventricular function are high operative risks. We present 101 patients who had mitral valve repair in our department: 21 had severely reduced left ventricular function, 19 were in NYHA functional Class IV, and 2 in Class III. All had concomitant coronary artery bypass.

There was no early operative mortality, but there were 2 late deaths (9.6%). At follow-up (3-36 months) all valves were functioning normally, 9 patients (43%) were in NYHA functional Class I, and 4 (19%) in Class II.

Our experience shows that repair of ischemic mitral insufficiency in the presence of severe left ventricular dysfunction can be performed with good results, and is preferable to mitral valve replacement. Late follow-up showed significant symptomatic improvement.

In the 1950's many IDF soldiers were hospitalized for heat stroke - about 25% of whom died. Analyzing these cases revealed that commanders misinterpreted human ability to perform in the heat and ignored basic concepts of fluid and electrolyte balance and heat load.

In the early 1960's a series of studies was conducted with regard to soldiers' performance in the heat. The first study (1959), which later became a classic, was conducted during a 21-day march from Eilat to Metula, crossing all climatic zones of Israel. The study was followed by other investigations which approached the issues of voluntary dehydration, fluid consumption vs sweat loss, salt additives, and the effect of heat load on performance.

Based on these early studies, proper regulations were issued to field officers. Over the years, the lessons learned from these studies saved many lives. The number of cases of heat stroke and of other climate-related injuries was dramatically reduced, and performance was enhanced.

The ability to predict the physiological responses of workers exposed to extreme environmental conditions, has been a challenge to environmental physiologists for more than 3 decades. Therefore, mathematical models have been developed to predict metabolic rate under various levels of work intensity and dynamic changes in body temperature and heart rate.

Based on the effect of exercise on the cardiovascular system, a model was developed to predict mean arterial blood pressure as a function of heart rate. Physiological strain could also be estimated on the basis of thermoregulatory and cardiovascular strains.

This paper summarizes knowledge accumulated during 25 years of studies in the field of mathematical modeling of physiological parameters. Besides analyzing the logic underlying each model, it explains the scientific approach in developing a model from its early concept to the model's application in the field.

The adult form of mononucleosis caused by Ebstein-Barr virus (EBV) is different from the disease in children and adolescents. In most adults there is no pharyngitis or lymphadenopathy, fever is much more prolonged, abnormal liver function is frequent and lymphocytosis and the presence of atypical lymphocytes are not common. Such an atypical disease presentation often results in delayed diagnosis and unnecessary treatments. We describe 2 adults with such atypical presentations and complications of EBV infection.

The increased rate of cesarean sections in recent decades has brought with it an increase in the frequency of placenta accreta. There are direct correlations between previous cesarean deliveries and also maternal age, with the risk of placenta accreta. There is also a direct correlation between placenta accreta and placenta previa.

The risk of placenta accreta in women who have had placenta previa is 2% for those younger than 35 years and with no history of uterine surgery. The risk increases to 39% for those over 35 who have had 2 or more cesarean sections.

We present 3 cases of placenta accreta admitted in 15 months, all of whom had a history of cesarean sections. The frequency of placenta accreta in our hospital is 1:1,579 deliveries, in line with the 1:1,420 in the literature. We consider hysterectomy the treatment of choice for this serious complication. When performing a cesarean in cases of placenta previa with a history of cesarean sections, the possibility of placenta accreta should be considered.
