Neuropediatric Unit, Shaare Zedek Medical Center, Jerusalem

Prader-Willi syndrome, first described in 1956, is characterized by marked hypotonia, hyperphagia, severe obesity, short stature, hypogonadism, orthopedic problems, breathing- related sleep disorders, mild to moderate mental retardation and behavioral abnormalities. The incidence of this syndrome, an expression of a genetic imprinting error in chromosome 15, is 1:10,000-1:25,000.

We describe the medical, emotional and cognitive parameters of 34 patients in our multidisciplinary clinic for Prader-Willi syndrome. Their ages range from 5 months to 40 years and 20 are males. Excessive weight gain started at the age of 6 years, increasing to 170-370% of that predicted by height and age and short stature started after the age of 12. All males have hypogonadism; 6 patients have scoliosis. Breathing-related sleep disorders have occurred in 15.

Children above the age of 8 years underwent neuropsychological assessment: half (9/18) have borderline intelligence while a quarter have low-normal intelligence and the remainder mild to moderate mental retardation. Behavioral and social problems are common, and become more prominent during adolescence. ADHD was diagnosed in 10/18.

Acute iron poisoning is a major cause of death due to poisoning in children, so knowledge of its presentation and appropriate management are necessary. Whole bowel irrigation, used routinely in preparation for elective surgery and colonoscopy, are safe and effective procedures. In recent years whole bowel irrigation has been used several times in various toxic situations, including acute iron poisoning.

We report our successful experience treating acute iron poisoning in a 1-year-old girl using whole bowel irrigation and deferoxamine. The safety and theoretical effectiveness of the procedure, although not proven in controlled clinical studies, suggests the use of whole bowel irrigation as treatment for acute iron poisoning.

Scaphoid Fractures in Children

The scaphoid is the most common carpal bone fractured in adults. In children the fracture is distinctly uncommon. We present our experience with 23 children treated between 1987-1998, 19 of them with fractures in the distal third of the wrist; there were 11 avulsions, 4 waist fractures, and 12 were undisplaced. The mechanism of injury was a direct blow or a fall onto the outstretched hand. Immobilization in a plaster cast led to union in all except 1 case.

Based on our experience and study of the literature, it is evident that scaphoid fractures, although uncommon, do occur. Thorough clinical and radiological examination of children with a forearm or wrist injury is important in detecting such fractures.

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.

Pre-induction sports participation of 392 elite infantry recruits was evaluated for correlation with incidence of stress fractures (SF) during 14 weeks of basic training. 23.7% developed lower extremity stress fractures. 72% of the recruits had participated in sports on a regular basis during the 2 years prior to induction. Their fitness as examined by the Bar-Or induction fitness test, was significantly better than that of those who had not trained. 14.9% of the soldiers who had previously participated in ball games (primarily basketball) as an only sport suffered stress fractures, compared to 31.0% of those whose only sport was running (p<0.005).

Training for only 6 months prior to induction had no effect on the incidence of SF. The reason for the difference between ball games and running is probably related to the higher strains and strain rates developed during ball games and to their multidirectional nature, as compared to running.

These findings suggest that participation in a pre-induction program that includes activities that create strains, such as basketball, can reduce incidence of SF in infantry recruits. The training period has to last at least 2 years.

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.

Military Psychiatry in Israel: a 50-Year Perspective 

Avi Bleich

Tel Aviv-Souraski Medical Center and Sackler Faculty of Medicine, Tel Aviv University

The history of military psychiatry in Israel may be divided into 2 main periods. The first extended from the War of Independence in 1948, through the Sinai, Six Day and Yom Kippur Wars. Its outstanding feature was avoidance of the issue of combat stress reaction (CSR). The Yom Kippur War made the recognition of CSR inescapable, assisted in breaking up denial, and served as a stimulus for development of the next phase of the system.

This second phase was characterized by impressive progress in all areas of military psychiatry. The rich experience accumulated during the wars, together with the assimilation of a research culture which began blooming, especially in the wake of the Lebanon War, aided the development and crystallization of concepts related to combat and non-combat military psychiatry alike. The build-up of the mental health organization overlapped field deployment of the Medical Corps.

In the past decade there have been far-reaching developments in psychopharmacology. Previously, only a few classes of medication were at the disposal of psychiatrists, as many had serious side effects that limited their use. Now our psychopharmacological armamentarium has grown considerably, allowing for greater choice of treatment in the military.

We review these developments, and discuss the special considerations to be taken into account when treating soldiers with psychiatric medication. We discuss suitable medication for ongoing outpatient treatment, as well as the standard list of medication currently used by units deployed in the field.

Advances in psychopharmacologic treatment should enable more soldiers to serve safely in the military with fewer restrictions on their duties.

Burn Injuries During the Six Day War

Dept. of Orthopedics, Bnai Zion Medical Center, Haifa

About 2500 soldiers were injured during the Six Day War (June 1967) of whom 115 suffered from burns. In 34 of them 15% or more of their body surface was involved and 11 died. Typical features of these burn cases were supplementary injuries, a high rate of infection, and long periods of hospitalization. Prophylactic antibiotics were not useful. The general condition of many deteriorated during the first week after injury, indicating the importance of treating severe burns in specialized facilities.

The War of Attrition between Israel and Egypt along the Suez Canal line lasted 23 months (9/1968-8/1970), during which the Israel Defense Forces (IDF) were mostly in fixed fortifications. A few of the important principles of field medical support, which became cornerstones of IDF procedure, were established during that war. These included use of armored vehicles for evacuation under artillery fire, as well as emergency treatment, physiological stabilization, and maintenance of the wounded until evacuation.

The latter objectives were achieved by stationing medical officers and paramedics within the fortifications, where they remained with the troops. A field surgical hospital was established in Refidim which had a trained surgical staff and a well-equipped emergency department. It included an operating theater and post-op recovery facilities for proper surgical care until evacuation to hospitals in the rear.

Tables showing the number of casualties throughout 1 year of the War of Attrition are presented. Better personal shielding by helmets and body shields decreased the number and severity of head and thoraco-abdominal injuries. The relative large number of those who died-of-wounds was due to the proximity of medical facilities, so that treatment could be administered within the fortifications. Otherwise, many more would have been included among the killed-in-action.

Non-Penetrating Deep Sclerectomy without Collagen Implantfor Glaucoma

Deep sclerectomy (DS) can be used in glaucoma with increased intraocular pressure when medical treatment fails. It involves removing part of the ocular drainage apparatus. Resistance to intraocular fluid drainage is decreased, improving drainage and decreasing intraocular pressure. By avoiding anterior chamber penetration, DS diminishes frequency of the complications of filtering surgery.

24 eyes of 23 patients underwent DS for primary or secondary open angle glaucoma with elevated intraocular pressure not controlled medically. It included preparation of a 4.0 x 4.0 mm limbal-based external scleral flap, dissecting and removing most of an internal scleral flap (leaving it 1 mm smaller than the external flap), unroofing Schlemm's canal and removing fine endothelial tissue lining its inner walls. The external scleral flap was then repositioned and sutured. Collagen implants were not used. In some cases DS was combined with extracapsular cataract extraction and intra-ocular lens implantation.

Mean intraocular pressure decreased from 24.8‏3.9 mmHg initially to 12.8‏4.4 mmHg 6 months after operation (p<0.0001). There was no difference in postoperative intra-ocular pressure between DS as a single procedure or as part of a combined operation. Comations were mild and of short duration.

If long-term follow-up shows that lowered intraocular pressures are maintained, DS should be a surgical option in earlier stages of glaucoma.

Constant advances and increasing experience in laparoscopic surgery renders it applicable for adrenal surgery. The wide exposure required for open adrenal surgery makes this minimally invasive procedure an attractive and advantageous alternative.

Between 1996-1999, we performed 35 laparoscopic adrenal-ectomies in 30 patients 20-72-years old. Indications included: Conn's syndrome - 14, pheochromocytoma - 11, Cushing's syndrome - 6, nonfunctioning adenoma - 3, and metastatic sarcoma - 1.

5 underwent bilateral laparoscopic adrenalectomy. In 3 (8.5%) the procedures were converted to open operations. Overall morbidity was 13% and there was no mortality. Mean operative time was 188 minutes, but only 130 in our last 10 cases. Mean hospital stay was 4 days and they returned to normal activity an average of 2 weeks later.

According to our study and previous reports, laparoscopic adrenalectomy is feasible and safe and it may soon become the procedure of choice for adrenal tumors.

The rich blood supply of the stomach protects it from ischemia and necrosis. Acute gastric ischemia, an emergency with high mortality, is rare. Atherosclerosis is the leading cause of acute ischemia, and the lesser curvature of the stomach is more vulnerable due to its relatively lesser blood supply. Reduction in gastric blood supply usually presents as chronic disease characterized by gastritis, gastric ulcer, or gastroparesis.

Gastroscopy can identify lesions of the gastric mucosa, and angiography demonstrates occluded vessels. Treatment of acute gastric ischemia is surgical, with total gastrectomy preferred over partial resection.
