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.

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.

An unselected series of 200 consecutive cases of major head trauma in children aged 6 months to 16 years, seen during 4 years, was studied. Injuries were due to road accidents (40%), falls (30.5%) and other causes (29.5%), and were assessed clinically and by cranial CT.

On admission the Glasgow Coma Score ranged from 4.72-11.65 and in addition to pupillary responses and brain stem reflexes, was a significant predictor of outcome. Brain edema, midline shift, intracranial hemorrhage and also hyperglycemia, hypokalemia and coagulopathy, were associated with poor outcome. While 17% died, 53% were discharged in good functional condition.

Early identification of clinical features related to prognosis can help the caring team provide maximal support for patient and family.

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.

The Helsinki Declaration contains recommendations guiding physicians who conduct clinical trials. One is that the requirement for informed consent is essential for approval of a trial. An important component of the informed consent doctrine is that all data required for the participant's decision must be provided. We analyze data of a therapeutic trial, and define 12 data components outlined in, or directly derived from the Helsinki Declaration.

61 instances of informed consent for therapeutic clinical trials from various fields of medicine, from 1994 to 1997, were analyzed. In each the presence of the 12 components was evaluated.

The data demonstrated that there were only 5 components cited in most cases of informed consent: trial objectives, methods, treatment plan, risks, and the option of withdrawing. Benefit to the participant was mentioned in half the cases, while only limited information was provided about other components such as life-threatening and unpredictable risks, and alternative treatment.

Examples of informed consent from 1997 showed statistical improvement since 1994 in the data concerning trial objectives, methods, risks and alternative therapy. Informed consent documents of international multicenter trials compared with local trials showed statistical improvement in the data components of the trial objectives, methods, and risks, including those of potentially life-threatening and unpredictable risks, and alternative therapy. Analysis of informed consent showed that not all components required for a comprehensive decision regarding participation in a clinical trial are included. These data emphasize the need to design a structured informed consent protocol in which all the required data components are specifically outlined for potential participants.

Prospective evaluation of intrahospittransportation of 33 critically ill children to and from the pediatric intensive care unit was conducted over the course of a month. Factors contributing to risk of transport were assessed.

There were 33 children (25 boys and 8 girls), 3 days to 15 years of age. Reasons for admission included: disease and trauma in 19, and status post operation in 11. The pretransport PRISM score was 4.84. 22 children (66.6%) were being mechanically ventilated and 10 (30.3%) were being treated with amines. Transport time ranged from 8-150 minutes. 15 of the transports (45.4%) were urgent and a special intensive care team escorted 22 (66.6%). Equipment mishaps and physiolog-ical deterioration occured in 12 (36.3%) and 11 (30.3%) of the cases, respectively. The use of amines, mechanical ventilation, longer transport time and high PRISM score were all associated with physiological deterioration on transport.

We performed 75 laparoscopic cholecystectomies during July and September 1996. In 3 men and 4 women, aged 32-87 years, there was obstructive jaundice caused by choledocholithiasis. During laparoscopy in the jaundiced patients, calculi were identified by cholangioscopy and intra-operative cholangiography. They were washed into the duodenum (confirmed cholangiographically) after intravenous glucagon injections and dilation of the papilla of Vater.

Serum bilirubin and liver enzyme levels returned to normal within a few days. There was no operative or postoperative morbidity, nor any biliary-related systemic complications. Average postoperative hospitalization was 3 days.

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.

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.

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.

CT-guided excision of osteoid osteoma is a new surgical technique that enables accurate resection of the nidus during 1-day hospitalization. We present 5-year results in 42 patients (26 males and 16 females, mean age 18 years, range 3-46). In 40 out of 42, complaints disappeared immediately after the procedure. The recovery period was short and the return to normal activity was faster than in the open surgical approach. Complications were minimal and transient.

Reactive Increase in Blood Pressure on Immobilization, but not Hypertension, Prevents Pressure Ulcers

Geriatric Dept., Rebecca Sieff Hospital, Safed

Of 135 geriatric patients immobilized for at least 2 days, 37 (27.4%) had pressure ulcers (PU). Those without PU were the control comparison group. Gender, length of immobilization, number of blood pressure determinations and proportion with hypertension were similar in those with and without PU. Those with PU were slightly older than those in the comparison group: 75.5±8.8 and 74.7±9.6 years, respectively (p>0.05).

Of 66 patients with acute ischemic stroke, reactive increase of systolic or diastolic blood pressure to 140/90 mm Hg or above following immobilization, was seen in 60.6% and 22.7% of patients, respectively, and there were PU in 12.1%. Of 17 with recurrent ischemic stroke, corresponding figures were: 41.2%, 23.5% (p>0.05), and 47.1% (p<0.01). In 7 patients with previous ischemic stroke corresponding figures were: 14.3% and 0% (p<0.01) and 100% (p<0.001). In 36 operated for fracture of the femur, corresponding figures were: 50%, 11.1% (p>0.05), and 27.8% (p>0.05). For 9 patients with severe infections, sepsis or pneumonia, the corresponding figures were: 22.2% and 0.0% (p>0.05), and 44.4% (p<0.04).

The proportion of patients with reactive increase in systolic blood pressure on immobilization was lower in the PU group than in the controls, 27% vs 59.2%, (p<0.001). The corresponding figures for reactive increase in diastolic blood pressure were similar, 8.1% and 20.4%, respectively (p>0.05).

The mean systolic blood pressure on immobilization was higher in the control than in the PU group, 145.4±21.7 and 130.8±14.9 mm Hg, respectively (p<0.001). The corresponding figures for the mean diastolic blood pressure were similar, 81.2±10.5 and 75.7±8.9 mm Hg, respectively (p<0.01). An increase in systolic blood pressure on immobilization reduced the risk of developing PU (p<0.05).

There was no significant statistical relation between diagnosis of hypertension and proportion of patients with PU (p>0.05). Of 67 patients with hypertension, in 23.9% and 74.6% of them there was no increase in systolic or diastolic blood pressure, respectively. Statistical difference between lack of diastolic or systolic response was very significant (p<0.001).

Reactive increase of blood pressure, but not hypertension, predicts reduced risk of PU on immobilization in the hospitalized elderly. Diminished reactive increase of blood pressure in response to stress of any kind may be a criterion of frailty and reduced physiological reserves. Efforts to reduce elevated blood pressure when a patient is immobilized appear irrational.

A-V Junctional Arrhythmia Due to Oral Phenytoin Intoxication

Phenytoin (Dilantin) is the drug of choice for most of the convulsive disorders. However, even when given orally it causes many adverse reactions, mainly affecting the nervous system, both central and peripheral. When administered intravenously, severe cardiovascular reactions may occur, including conduction disorders, sinus arrest, atrioventricular block or hypotension.

Medline screening did not reveal previous reports of arrhythmias induced by oral phenytoin. We present a case in which oral phenytoin administered chronically for a convulsive disorder caused atrioventricular junctional arrhythmia.

Knowledge and practice of primary care physicians as to diagnosis and treatment of group A, b-hemolytic streptococcal pharyngitis, and the degree to which they agreed with the medical literature and current clinical guidelines were examined. The study was conducted in a group of 195 general physicians, pediatricians, and family medicine specialists and residents. The data were collected using questionnaires which included personal information and questions relating to b-hemolytic streptococcal pharyngitis and were analyzed by chi-square and t-tests, and logistic regression, as appropriate. A new dependent variable, good clinical practice (GCP), was defined as the total number of correct answers to the questions in the questionnaire. 147 of the 195 eligible physicians returned completed questionnaires, a compliance rate of 76%.

96.6% cited pV as the drug of choice at a daily dosage of 1 g (43.7%) or 2 g (25.4%), for 10 days (90%). 133 physicians (90%) stated that the goal of penicillin therapy for beta-hemolytic streptococcal pharyngitis is to prevent late complications. 116 physicians (82%) cited rheumatic fever as a complication of group A beta-hemolytic streptococcal pharyngitis, preventable by appropriate antibiotic therapy. However, only 84 (59%) cited glomerulonephritis as a preventable complication.

When the knowledge and attitudes of the respondents was analyzed in terms of the new variable, GCP, a significant association (p<0.001) was found between physicians’ attitudes and variables such as where they had studied medicine, and work seniority. Those with less seniority and or medical graduates of the Americas demonstrated greater knowledge and better clinical judgment than their more senior colleagues and graduates of European and Asian medical schools. Most primary care physicians in northern Israel treat group A b-hemolytic streptococcal pharyngitis as recommended in the medical literature.

The level of medical studies in Israel and the Americas and the quality of training of residents in family medicine and pediatrics, have a positive influence on the degree of knowledge of as common a subject as b-hemolytic streptococcal pharyngitis. Emphasis should be placed on continuing medical education among primary care physicians, particularly veteran general physicians and those who studied in European or Asian medical schools.

Nerve paralysis following the use of tourniquets, regular or pneumatic, for limb surgery is rare. We describe a 19-year-old male soldier who had tourniquets applied for 3 1/4 hours to his arm and both legs due to penetrating injuries. As a result, he suffered palsy of the radial nerve and both common peroneal nerves. Nerve palsy in such cases has not been described in the literature. It is not clear whether the cause is direct mechanical pressure on the nerve, nerve ischemia, or a combination of both.

We recommend that tourniquets should not be used continuously for more than 2 hours. If evacuation of the injured is delayed, the medical team should consider loosening tourniquets for short intervals or changing for a pressure bandage. This is providing the patient's condition is stable and bleeding does not start again on release of the tourniquet.
