Knowledge of Adolescents about the Fetal Alcohol Syndrome

Prevention Department, Israel Society for the Prevention of Alcoholism, Ramat Gan

The level of knowledge of the risks of drinking during pregnancy in 175, 17-18 year olds from kibbutzim in the eastern Upper Galilee was studied in January 1996. This population had the highest rate of involvement with alcohol in Israel and had been involved in alcohol education activities in previous years. About 53.71% of the sample believed that heavy drinking increases the risk of birth defects, but only 20.57% could correctly describe the fetal alcohol syndrome.

In the past 20 years Hickman catheters have gained increasing acceptance for many uses, including bone marrow transplantation, long-term chemotherapy, total parenteral nutrition, dialysis, and administration of antibiotics and fluids. Until the past decade these catheters were inserted in the operating room. We present our experience in the percutaneous placement of 203 Hickman catheters in an interventional radiology suite in 190 consecutive patients within a period of 30 months. Catheter placement was successful in 202 (99.5%). The main complications were infections, necessitating removal of the catheter in 11 cases (5.4%) and unintentional dislodgement of the catheter in 8 (3.9%) - all in women and most on the right side. Pneumothorax and thrombosis in the catheter each occurred once. In another patient the guide wire broke during insertion and had to be percutaneously removed from the pulmonary artery. Late fracture of the catheter occurred in 2 others in whom the intravascular fragment was removed percutaneously. We believe that percutaneous Hickman catheter placement in the radiology suite offers advantages over traditional surgical placement.

Transitional cell carcinoma (TCC) with trophoblastic differentiation (TD) is a newly recognized variant of urothelial cancer which produces placental proteins, predominantly beta-human chorionic gonadotropin (HCG). It has a poor prognosis. About 210 cases were described, mostly from North America, Europe and Japan. This is the first report of TCC TD in a resident of Israel's upper Galilee. A 69-year-old man whose urinary papillary bladder tumor was established cystoscopically, refused treatment and stopped follow-up. 3.5 years after his last visit, he returned and cytologic examination revealed malignant urothelial cells, while intravenous pyelography disclosed a urinary bladder defect. Cystoscopy showed numerous papillary masses dispersed over the bladder mucosa, which were resected transurethrally. Histopathologic examination revealed TCC grade III, stage A. Tumor cells were immunopositive for beta-HCG and human placental lactogen. 4 transurethral resections of large masses were performed within 2 months. Pulmonary metastases developed and the patient died 4 years after the detection of the urinary bladder tumor.

Gonadotropin-Releasing Hormone (GNRH) in Selecting Patients for Varicocelectomy

The gonadotropin-releasing hormone (GnRH) test was performed on 182 patients with various degrees of varicocele before and after low, inguinal, spermatic vein ligation, and on 18 controls. The levels of follicle-stimulating hormone (FSH) and luteinizing hormone, a synthetic GnRH (LH), were evaluated before and 45 minutes after intravenous injection of 100 mcg relisorm L. FSH levels increased more than 2-fold in 118 patients [64.8%] and LH levels increased more than 5-fold in 135 patients [74.1%]). In the control group the increase was less in all cases. Therefor, whenever FSH increased more than 2-fold and LH more than 5-fold, we considered the test positive (pathologic); On this basis the GnRH test was positive in 126 (69.2%) and negative (normal) in 56 (30.7%). Of the 126 with positive tests, only 32 (27.3%) still had a positive result 5-6 months after operation. There was correlation between a positive GnRH test and significant improvement in sperm parameters after varicocelectomy: of the 126 with positive tests before operation, sperm parameters improved in 87 patients (69%), while in the 56 patients with negative tests before operation, in only 7 (12.5%) was there improvement after correction. We conclude that a positive GnRH test indicates impairment of the hypothalamic-pituitary-gonadal axis caused by varicocele and could serve as a marker for surgical intervention with good prediction of outcome.

Radiation-Induced Meningioma: The Changing Pattern of the Disease

In this country radiation-induced meningiomas were usually associated with low-dose irradiation of the scalp of immigrants from North Africa, given as part of the treatment of tinea capitis. An Ashkenazi patient developed meningiomas 15 years after high-dose irradiation for a benign lesion in the parasellar region. The accumulating literature about high-dose radiation-induced meningiomas is reviewed and attention is drawn to the ever increasing number of meningiomas observed in immigrants from the former Soviet Union.

Familial Adenomatous Polyposis: Establishing a Registry and Genetic and Molecular Analysis

Familial adenomatous polyposis (FAP), a dominantly inherited disease, is caused by a mutation in the adenomatous polyposis coli gene in chromosome 5q21. The gene has 15 exons, a physical length of 10 Kb and an open reading frame of 8.5 Kb. Exon 15 codes 66% of the mRNA and has a mutation cluster region which accounts for over 50% of mutations. The disease usually leads to the appearance of hundreds of adenomatous polyps in the transverse and descending colon between puberty and age 20 years and to colon cancer before the age of 40. Early detection is essential to prevent the development of metastasizing cancer. Since 1994 we have recruited 23 families for genetic counseling. DNA was obtained from 19 unrelated FAP patients and 219 high risk relatives in 19 unrelated families following confirmation of the diagnosis. In addition to linkage studies, direct mutational analysis was performed using the protein truncation test for most of exon 15 and single strand conformation polymorphism analysis for the other exons. These exons account for most of the mutations identified to date. Of 19 unrelated probands, 14 had detectable mutations. Exon 15 accounted for 6 families, exons 5, 7 and 14 for 1 each, exon 9 for 3, and exon 8 for 2. Combined mutational and linkage analysis identified 18 presymptomatic carriers who received genetic and clinical counseling. Our FAP patients did not differ significantly from those of larger studies in other countries with regard to the distribution of the mutations, gender and genotype-phenotype correlation, or ethnic distribution.

Temporal Hemianopia And Diabetes Insipidus Following Head Injury

Bitemporal hemianopia and diabetes insipidus following head injury are caused by a lesion in the center of the optic chiasm, together with injury to the adjacent pituitary stalk or the hypothalamus. This combination was thought to be a rare complication of severe head injury. The case of a 16-year-old male is presented, which together with recent reports suggests that this relatively under-recognized syndrome is not infrequent, that it may follow even minor head injury, and that magnetic resonance imaging can demonstrate the chiasmal lesion.
