The 4 allele of the APOE gene, coding for apo-lipoprotein E, is the most common genetic risk factor for Alzheimer's disease and a significant risk factor for coronary atherosclerosis. There is therefore much interest in studying its frequency in different ethnic groups.

We examined its frequency in Jews originating from Libya, Buchara and Ethiopia and in Jews of Sepharadi and Ashkenazi origins. Its frequency among Ethiopian immigrants was 0.27, significantly higher than in the other groups, in which the frequency was between 0.067 and 0.10. These differences in allele frequency may serve as a basis for future studies in Israel to assess the relative contributions of genetic and environmental factors to the incidence of dementia.

We present our initial experience with retroperitoneoscopic lumbar sympathectomy in a series of 5 men aged 25-45 years. 3 suffered from ischemia of the lower limbs due to Buerger's disease, 1 had severe reflex sympathetic dystrophy and 1 had vasculitis with severe, non-healing lower leg ulcers.

The right retroperitoneal space was developed with a dissecting balloon-trocar introduced via a small lateral muscle- splitting flank incision. 2 additional 5 mm trocars were used for instrumentation and clipping. L2-L3 or L3-L4 ganglia were resected; mean operating time was 120 minutes. Only oral analgesics were needed for postoperative pain control and oral food intake was resumed the following morning. The procedure was successful in all and was without complications. Mean hospital stay was 2 days.

All patients reported significant relief of ischemia or dystrophic pain and/or improvement in trophic changes in the extremities. In the patient with leg ulcers, the largest was successfully covered with a skin graft. The retroperitoneoscopic approach to lumbar sympathectomy successfully combines the advantages of minimal invasive surgery and the reliability and effectiveness of well-established open sympathectomy.

Reference to alternative medicine frequently appears in newspaper headlines, advertisements and in articles in medical journals. The practice of alternative medicine has increased, even as the number of critical articles warning of deleterious effects have also increased. Public demand is strong and growing, but there are no clear rules as to what is not permissible, particularly when treatment is not by qualified physicians. There are still no clear indications and contra-indications for complementary (not alternative) medicine in patients with organic injuries and life-threatening conditions. However, it is obvious that in these patients complementary medicine should not be substituted for conventional therapy.

We present a 32-year-old man with sarcoidosis who discontinued conventional therapy on his own initiative and began alternative medicine (homeopathy) with subsequent deterioration in his condition. He was hospitalized for a relapse of his sarcoidosis which required large doses of corticosteroids.

Several studies have documented the impact of clinical pharmacy services on patient care and drug costs in hospital wards. However most hospitals in Israel do not provide such services and until recently their benefits in local health care have not been demonstrated. We therefor determined whether the activity of a pharmacist in the medical department of a medical center leads to improved quality of drug utilization and reduced costs.

During the first 3 months of the clinical pharmacist's work all interventions and consultation were documented. The effect of these interventions on drug costs was calculated by the change in drug acquisition costs during the study period compared with those of preceding months, as well as in the other 5 medical departments of the hospital without clinical pharmacy services.

During the study period the pharmacist joined 44 clinical rounds in which he documented 40 consultations in response to physicians' requests for drug information and 42 interventions on his own initiative. The pharmacist's recommendations were accepted in 38 of the 42 cases (90%). In 10 cases the pharmacist's initiative in improving the quality of drug therapy led to an increase in drug acquisition costs. However, the overall drug costs during the study period decreased 12.6%. During the same period drug costs in the other medical departments decreased only 2.2%.

The results of this study conform with those of many other studies that show a beneficial impact of the clinical pharmacist on the quality of drug therapy and on drug costs. They indicate that the clinical pharmacist can play a crucial role in the medical department.

Nephron-Sparing Surgery - Initial Experience with 50 Patients

During recent years the use of the new imaging techniques, ultrasonography and computerized tomography, has increased. The accessibility to these methods has changed the pattern of detection of renal lesions. Over 90% of renal masses are now discovered incidentally, while investigating nonurological symptoms. Therefor, most lesions are discovered in their early stages.

The gold-standard procedure for removing renal masses is radical nephrectomy, which ensures complete removal of an organ-confined lesion, but involves loss of functional tissue. This might be critical in patients with a single kidney, or reduced nephron function. There are several diseases characterized by multiple renal lesions, such as Von Hippel-Lindau and tuberous sclerosis in which radical treatment may lead to chronic dialysis in young patients.

Nephron-sparing surgery was developed in order to preserve as much functional tissue as possible while removing safely any suspicious renal lesion. This new technique, not involving radical surgery, should be evaluated in cases of renal tumors for its ability to achieve the same cancer cures rates. We present our experience with our first 50 patients who underwent nephron-sparing surgery for removal of renal lesions.

Pediatric care in the community is gradually replacing traditional care in hospitals. Despite that, research activity in the community setting is minimal due to objective difficulties. These are mainly constraints of time, office work and lack of research-supporting logistics. In the past decade, throughout the world, primary physicians interested in research have grouped together and formed research networks. The aim of such networks is to support and promote research in the community.

An Israel Pediatric Research in Office-Setting network (IPROS) was established 2 years ago by the Israel Ambulatory Pediatric Association (IAPA). Today, there are over 140 pediatricians listed in IPROS, representing the heterogeneous composition of pediatricians in Israel. The network's policy is defined by a joint steering committee. The committee is composed of IAPA representatives, senior network members and Schneider Hospital senior investigators. The research subjects are diverse, and represent common practical issues.

Effective intra-net communication is vital to the existence of the network, and is accomplished by 3 modalities: 1) semiannual updates by mail, 2) e-mail, using an electronic mailing list to facilitate connection between members, 3) semi-annual meetings. Research budgets are derived from public sources like the Ministry of Health and IAPA, and private sources such as pharmaceutical companies. The administration of the network is supported by Schneider Children's Medical Center, and financed by IAPA.

To determine the results of the conservative approach in the treatment of pediatric abdominal trauma, we retrospectively analyzed data from the files of 95 cases of abdominal trauma in children during a 5-year period.

51 patients (54%) had isolated abdominal injury, while 44 (46%) had multiple trauma. The most common causes of injury were road accidents and falls from heights (74%). CT scans were performed in 61 (64%) with positive results in 90%. Ultrasonography was done in 22 (23%) and was positive in 55%.

The spleen was the most vulnerable intra-abdominal organ (33 patients, 35%), as well as the organ most severely damaged. Other injured organs were: liver (30 cases), kidney (16), stomach (2), large blood vessels (2), and pancreas, duodenum and diaphragm (1 case each).

83 patients (87%) were treated conservatively, while 11 were operated on for penetrating abdominal trauma (3 cases), hemodynamic instability (3), positive DPL (3), and Scale 4 splenic injury and free intra-abdominal air on CT scan (1 case each). Early and late complications were mild.

It is concluded that CT is an efficient and reliable imaging method for diagnosis and staging of severity of injury in blunt abdominal trauma. Nonoperative management of solid organ injuries under careful observation in a pediatric trauma center is safe and appropriate. Most Scale 4 splenic injuries can be treated successfully without surgical intervention. Using this conservative approach there were no late complications.

Critical illness polyneuropathy developed in 8 patients aged 22-84 years in our intensive care units. This acute polyneuropathy, predominantly axonal and motor, develops in the setting of the systemic inflammatory response syndrome and multi-organ failure. It is found in about 50% of patients treated in intensive care units for more than 2 weeks. In those who survive, neurological and functional recovery is the rule.

The renin-angiotensin system is thought to play an important role in the pathophysiology of kidney disease in diabetes. Previous studies have shown a possible association between the D allele of the angiotensin converting enzyme (ACE) gene, known to be associated with higher circulating levels of ACE, and increased risk of developing nephropathy in NIDDM. The present study investigated the distribution of ACE gene genotypes in the general population and patients with NIDDM, the association between the D allele and diabetic nephropathy, and the association between the ACE genotype and involvement of other target organs in NIDDM. The ACE genotype (insertion/deletion I/D) was determined in all subjects, subsequently divided into 3 groups based on their polymorphism (DD, DI and II). The presence of nephropathy was defined by an albumin-creatinine ratio of 30 mg/g or greater (mean of 2 first morning urine samples).

In the general population most had the D allele (DD or ID) and a minority the II genotype. There was no association between genotype and hypertension, ischemic heart disease, hyperlipidemia, and cerebrovascular or peripheral vascular disease. In diabetics the genotype distribution was not different from that in the general population. Within the diabetic group, there was no association between genotype and hypertension, hyperlipidemia, duration of diabetes, or HbA1C levels. Nephropathy, found in 81 of the 156 with NIDDM, was not associated with genotype. Diabetic nephropathy was not associated with retinopathy, neuropathy, or ischemic heart, cerebrovascular or peripheral vascular disease. We conclude that in the population sampled, there was no association between the D allele of the ACE gene and the risk of developing nephropathy in NIDDM.

Determining Power Factors of Clinical Departments in a Medical Center

Netta Notzer

Medical Education Unit, Sackler Faculty of Medicine, Tel Aviv University

The intradepartmental power factors in a medical center were studied. 3 strategic contingency factors were examined, based on the model of Hickson et al. (1971): centrality, substitutability, and coping-with uncertainty. Only coping-with-uncertainty contributed directly to departmental power, and not the summation of the 3.

Power derives from department resources, connections and influence outside the medical center. Aspects related to in- patient treatment or teaching of residents did not contribute directly to departmental power status. Power is gained in stages: in the first the department contributes to the factor of centrality (mainly patient treatment, teaching and research). In the middle stage, power is gained due to the factor of substitutability- the unique services and research which the department has developed. The third stage contributes directly to power-coping with uncertainty. This implies the ability of a department to solve crucial problems of the medical center. Surprisingly, the clinical field (i.e. surgery) did not contribute significantly to power. The current trend is toward empowering ambulatory units in the medical center.

Plagiocephaly in a head-and-neck irradiated rat model or rhomboid-shaped head, occurs in at least 1 in 300 live births. In most cases such asymmetry is not caused by synostosis of the unilateral coronal or lambdoid sutures, but is rather a deformity produced by intrauterine and/or postnatal deformational forces. Categorization and diagnosis of plagiocephaly as synostotic or deformational is reliably made by physical examination and computerized tomography. Its differential diagnosis is extremely important because prompt surgical correction is usually indicated for the synostotic type. In contrast, infants with deformational frontal or occipital plagiocephaly generally respond to helmet treatment.

10 infants with significant deformational plagiocephaly were treated with individual plastic helmets during the past 2 years and 4 other infants with plagiocephaly are currently being treated. In each instance, cranial asymmetry dramatically improved as the brain grew and the head filled out the helmet. There were no significant complications. Awareness of deformational plagiocephaly allows more accurate diagnosis and appropriate treatment, avoiding unnecessary surgical intervention in patients with positional molding.

Bulimia nervosa (BN) is an eating disorder frquently accompanied by changes of the hard and soft tissues of the oral cavity and of the salivary glands. Routine dental examination in a 25-year-old woman disclosed oral signs and symptoms characteristic of BN and she was referred for psychiatric evaluation. Oral evaluation of patients suspected of BN is recommended to prevent irreversible damage to the oral and perioral structures.

Soft tissue sarcomas are exceedingly rare, making up less than 1% of all solid malignancies. In the retroperitoneum, they tend to be large when diagnosed and are a therapeutic challenge to the surgical oncologist. Our experience with 51 patients with retroperitoneal sarcomas operated on during the past 4 years is presented. 37 were primary and 26 presented as recurrent tumors. The group included many different histological sub-types, the majority being high grade tumors.

Complete resection was achieved in 84%, necessitating extensive surgery, but was not possible in 8 patients (16%) who underwent partial resection or biopsy only. There was 1 perioperative fatality (2%). 18 (35%) suffered complications, all of which were reversible. The estimated 5-year survival in the complete resection group is 40%, while none of those who underwent partial resection survived more than 2 years. There was significantly better survival in patients with primary, low grade sarcomas which were smaller than 8 cm, compared to those with high-grade, recurrent sarcomas larger than 8 cm. Local recurrence developed in 8 patients of the complete resection group (18%), 2 months to 3 years after surgery.

These data show that despite the concept of retroperitoneal sarcomas as being aggressive, invasive tumors with a poor prognosis, the prognosis is not unusually bad. With proper surgical technique, resectability may be high, with improved overall survival.

Stress urinary incontinence is a medical and social problem. In the past decade there has been increased awareness of this condition and the number of those affected who seek help is increasing. Treatment is usually surgical - elevation of the bladder neck. Pelvic floor exercise is an accepted conservative treatment modality used for mild to moderate cases that have not yet completed their families.

We present our results in 30 women, aged 28-71 years, av. 49% with genuine stress incontinence treated with pelvic floor exercise and biofeedback. 14 patients (46.7%) were completely cured and 15 (50%) were improved. In only 1 was there no improvement.

Our results show significant improvement in the duration and intensity of pelvic floor contractions after treatment. Pelvic floor exercise with biofeedback is a very important treatment modality, requiring a highly motivated patient and a physiotherapist specialized in pelvic floor exercise.

Subacute thyroiditis may be hard to diagnose, therefore patients are sometimes misdiagnosed and subjected to unnecessary work-up. We report a 37-year-old man with subacute thyroiditis and a high concentration of serum alkaline phosphatase. After aspirin treatment there was clinical improvement and decrease in rapid ESR, and in high serum thyroxin and alkaline phosphatase. The increased alkaline phosphatase, seen in as many as 50% of patients, is of hepatic origin, and is not caused by high serum thyroxin. Awareness of this relationship may help in diagnosis and may prevent unnecessary diagnostic procedures, which may be invasive.
