Depts. of Radiology and Pathology, Hadassah-University Hospital, Jerusalem

CT-guided core needle biopsy of abdominal, pelvic and retroperitoneal masses is accurate and safe and can be performed on an outpatient basis. Between 1987 and 1995, 809 patients (age range 1-87 years) underwent 851 biopsies (minimal lesion diameter 1 cm). Cutting needles were always used, facilitating both cytological and histological diagnosis while minimizing risk of complications. A positive result (malignant, inflammatory or infectious) was obtained in 69% of the 809 and a negative result (normal tissue) in 17.4%, while in 13.6%, material for diagnosis was insufficient. Biopsy was repeated in 42 of them in whom radiological or clinical suspicion of malignancy was high. In 24 (60%) a positive result was obtained after the second biopsy.

Significant complications occurred in 7 (0.8%). 1 hemo-rrhaged following liver biopsy and required blood transfusion. Pancreatitis occurred in 6 (2.6%) following pancreatic biopsy. An intra-abdominal fluid collection in 1 necessitated percutaneous drainage. There was no mortality following the procedure and no documented case of needle-tract seeding of tumor. All outpatients were discharged within 3 hours of completion of the biopsy, without ill effects.

Cellular Phone Interference with Medical Instruments

Medical Engineering Dept., and Administration, Hadassah-University Hospital, Ein Kerem, Jerusalem

Cellular telephones and other telecommunication equipment occasionally cause malfunctioning of medical equipment, including life-support equipment. We review such malfunctioning and relate it to Israeli and worldwide standards, analyzing the characteristics of the interference in terms of amplitude and frequency. The results of a controlled study of interference by cellular telephones and portable 2-way radios with medical devices in our clinical departments are also presented. The levels of background environmental electromagnetic noise at several sites in both Hadassah hospitals (Ein Karem and Mount Scopus) were measured, as well as signal levels of cellular telephones and other communication equipment at various distances and in various areas. We recommend 2 different levels of restrictions on the use of this equipment within the hospital.

These include prohibition of the use of wireless telecommunication equipment in intensive care areas and operating theaters. In all other areas it is recommended to turn off the cellular telephone within 1 meter of medical devices and not to transmit (but only to receive) calls with a portable 2-way radio within a 5 meter distance of medical devices.

"Charge" Association

Pediatric and Neonatal Depts., and Clinical Genetic Unit, Kaplan Hospital, Rehovot

CHARGE association represents a group of congenital anomalies with no clear etiology. The broad array of abnormalities, which involves several systems, has been the basis for the acronym CHARGE: coloboma, heart anomaly, choanal atresia, retarded growth and development, hypoplastic genitalia and ear malformation. We present 3 children with CHARGE association to illustrate the phenotypic variability and note the multidisciplinary treatment they received. It is recommended that this entity be approached in an interdisciplinary, integrated way to allow for faster diagnosis and better prognosis.

Depts of Maxillofacial and Oral Surgery, Rambam Medical Center, Haifa

This department was established 35 years ago. Since then, many patients with facial trauma, both soldiers and civilians, have been treated and extensive experience has been accumulated. From 1990 to 1995, 487 patients with facial trauma (18.6% of the patients in the department) where hospitalized and treated. 88.5% suffered from injuries which included facial bones, and the others from soft tissue injuries only. We summarize our experience, analyzing both the demographic and clinical characteristics of the injuries and the treatment administered. Based on our experience and the current literature, we present an overview of the issue.

Separation of Conjoined Twins: The Anesthesiologist's Perspective

Dept. of Anesthesiology, Rabin Medical Center, Beilinson Campus and Schneider Children's Hospital, Petah Tikva

Managing anesthesia care for separation of conjoined twins poses a special challenge for the anesthesia team. Early preparation, thorough understanding of the anatomical and the physiological consequences of this complex anomaly, as well as careful coordination with the teams of surgeons, nurses and operating room personnel are mandatory to assure successful separation of the conjoined twins. It is recommended that the mother be transferred to and the babies be delivered at a tertiary care medical center, like the Children's Hospital. Special attention is devoted during the surgical procedure to cardiovascular stability, drug disposition, fluid balance and temperature control. The multidisciplinary team approach makes this complex surgery a success. When postoperative survival cannot be guaranteed for both twins, close contact and consultation is mandated with the parents, medical personnel and religious and legal advisors.

Blunt perineal and anal injuries are rare. We describe 2 patients who suffered injury to the perineum and anal canal due to blunt force. New surgical techniques for the reconstruction of the sphincteric mechanism are promising and should be used by the initial treating surgeon as minimal procedures in the perineal region. Anal tagging, minimal debridement, approximation of the edges of perineal laceration, repeated irrigation and loop-colostomy for fecal diversion should be the only initial surgical procedures.

Anesthesia Dept. and Intensive Care Unit, Hadassah Hospital, Jerusalem

Although significant progress has been made in the past 2 decades in our understanding of pain pathophysiology and in the development of new analgesic drugs and techniques, many patients still experience considerable pain during hospitalization. Unrelieved pain is common not only among patients undergoing surgery, but also in those with a variety of other medical problems. These findings led to the development of our in-hospital acute pain service. This in-hospital pain service has been active since the late eighties, treating both postoperative pain and non-surgical pain in hospitalized patients. During 1995, 2140 patients were treated totaling 8717 treatment days in 18 different medical units and departments. Overall success was more than 75%. We review our experience in treating in-patients who suffer from pain and discuss future trends and need for such a specialized service.

On the Value of the Placebo: Reflections on Homeopathy

Pesach Lichtenberg

Dept. of Psychiatry, Herzog Hospital, Jerusalem

A case is presented in which homeopathic "treatment" helped, despite the fact that the patient did not take the medication. The author surveys research which has been conducted on homeopathy and concludes that its benefits derive from non-specific influences of the healer upon the patient, similar to a placebo effect. The importance of this influence is stressed, and its wider application in conventional medicine is urged.

A worrisome connection between driving and drinking was found in 166 people randomly surveyed in public places in Beer Sheba. 80% of the study population stated that they drink alcoholic beverages. Of these, 45% reported drinking at least once a week, and 21% drank 3 glasses/cans at each drinking bout. We noted a trend among those who drank frequently to drink greater amounts. Of the sample, 110 interviewees stated that they had a driver's license and that they drank alcoholic drinks. 39% reported driving after a number of alcoholic drinks, and 23% of them did so invariably or frequently. 5% drank while driving. The drinkers exhibited a high-risk behavioral pattern, remaining in the car with friends (53%) or relatives (16%) also under the influence of alcohol. Those who are aware of the influence of alcohol on their driving skills and the danger of being involved in car accidents, moderate their consumption of alcohol. The results of the study confirm our hypothesis that there is an upswing in the phenomenon of high-risk driving connected with drinking alcoholic beverages.

Evidence For Casual Household Transmission Of Hiv: Review And Analysis

Micha Razel

School of Education, Bar-Ilan University, Ramat-Gan

All reported case-studies in which the author-described route of infection was deemed to be casual household contact were reviewed and analyzed, as well as all sample-based studies designed to estimate the frequency of casual household transmission. Several recurring biased mechanisms of interpretation were found in the studies, the use of which made it impossible to obtain evidence for casual household transmission. After correcting for these interpretations 8 documented cases of casual household transmission were found. Analysis of the sample-based studies indicated 10 cases of casual household transmission, which occurs at a risk of 0.4% per year of contact (95% confidence interval: 0.20 to 0.66).

Kapoera, a combination of acrobatics and coordinated athletic movement, is believed to have been introduced to South America during the 19th century by transported African slaves. The dance does not involve intentional physical contact, but during 6 months, 3 patients were admitted here for injuries induced by the forceful movements of this dance. 2 underwent exploratory laparotomy that revealed bowel perforations and 1 suffered a comminuted nasal bone fracture. Medical personnel should be familiar with the potential hazards of this dance and martial art.

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.

In recent years there have been numerous reports of successful treatment of resistant ulcerative colitis with cyclosporin. A series of 9 patients with moderate to severe active ulcerative colitis was treated with cyclosporin between September 1993 and October 1994. All 9 had failed to respond to conventional therapy, including salazopyrine and intravenous corticosteroids. They underwent colonoscopy and after contraindications to therapy were ruled out, received intravenous cyclosporin, 4 mg/kg/day for 7-10 days. They were discharged on oral cyclosporin with average serum levels maintained at 200 ng/ml. Response was assessed using the clinical score system of Schroeder et al. 2 out of 9 patients (22%) responded with full clinical remissions lasting more than 6 months. 6 patients had partial responses to the intravenous therapy, but symptoms resumed shortly after its cessation. Factors predicting favorable response to cyclosporin therapy were a shorter duration of disease with a fulminant clinical course. The success rate was less than that reported in the literature, possibly because of comparatively low serum cyclosporin levels. Potential complications of therapy and high cost preclude the routine use of cyclosporin in ulcerative colitis. Larger controlled studies are required to assess its efficacy and safety. Until such studies are available, cyclosporin may be tried in poor surgical risks or those not yet ready psychologically for total colectomy.

Volume reduction surgery (VRS) is a new procedure based on the concept that relieving hyperinflation in emphysema improves diaphragmatic and chest wall mechanics and ventilation perfusion mismatch. We present our early experience with 16 patients who underwent VRS from August 1995 to June 1996. Patient selection was based on: PFT, CT scan, V/Q scan, ABG's and 6-min walk. After pulmonary rehabilitation, operation was by median sternotomy and bilateral lung shaving. Pulmonary function improved significantly. FEV1 increased from 0.68 ± 0.2 to 1.0 ± 0.2 L (p<0.01) and FVC increased from 1.7 ± 0.5 to 2.7 ± 0.5 L (p<0.017). Total lung capacity decreased from 129% ± 24% to 108% ± 20% (p<0.03). 6-min walk increased from 221 ± 90 to 404 ± 123 meters (p<0.001). Complications included 1 death, prolonged air leak in 7 cases and infection in 2. Quality of life improved substantially in 12 of the 16 cases; in 3 cases there was only slight improvement and in 1 the condition became worse. Volume reduction surgery is a promising surgical solution in selected patients with advanced emphysema.

The visual outcome in 23 men and 2 women with traumatic cataracts was analyzed retrospectively. Their average age was 33 and they ranged from 10 to 69 years. Surgical results were either very good or very poor. Associated retinal injuries significantly decreased final visual acuity (p = 0.001). Those with initial visual acuity restricted to finger counting had better visual results than those with initial visual acuity restricted to light perception (p = 0.01) and hand motions (p = 0.02). Usually the lens was removed via the pars plana; the most common mode of optical correction was contact lenses.
