Desynchronization of circadian rhythmicity resulting from rapid travel through at least 4 time zones leads to symptoms of jet lag syndrome. The most commonly experienced symptoms in normal individuals are sleep disorders, difficulties with concentrating, irritability, mild depression, fatigue, and gastrointestinal disturbances.

There is strong evidence relating affective disorders to circadian rhythm abnormalities, such as occur in jet lag. Less convincing suggestions relate jet lag to psychosis. We presume, relying on the literature and our accumulated experience, that in predisposed individuals jet lag may play a role in triggering exacerbation of, or de novo affective disorders, as well as, though less convincing, schizophreniform psychosis or even schizophrenia. An illustrative case vignette exemplifies the possible relationship between jet lag following eastbound flight and psychotic manifestations.

Color Doppler imaging (CDI) is a noninvasive technique, combining 2-dimensional brightness-modulated (B-mode) ultrasound evaluation of eye and orbital structures, with simultaneous color-coded Doppler imaging of orbital blood flow. It has been used to characterize various ophthalmic disorders in adults. Currently there is no data describing orbital blood flow parameters in either normal children or in those with ophthalmic disease, such as the retinopathy of prematurity (ROP).

We evaluated blood flow in the central retinal artery of preterm infants undergoing examination for ROP. We also investigated whether useful readings could be obtained on a consistent basis, and the reproducibility of differences in central retinal artery blood flow between subjects with and without ROP (including the influence of "plus" disease).

We obtained hemodynamic readings in 43 of 46 eyes of preterm infants. 13 eyes had no signs of ROP; 18 had ROP (at least stage 1) without "plus" disease, and 12 had ROP with "plus" disease. There were no statistically significant differences in systolic blood flow velocity within the 3 groups. However the average velocity was slower in the "plus" disease group, correlating with the clinical finding of dilated and tortuous blood vessels which characterize the posterior retina of ROP eyes with "plus" disease.

Many physicians, civilian as well as in military, feel that some referrals of soldiers to civilian emergency departments are inappropriate and that soldiers should receive medical attention within their military units. We therefore evaluated referrals of soldiers to our emergency department.

707 referral letters from military physicians and the corresponding emergency room discharge letters were evaluated. Most soldiers were referred for mild trauma (45.0%) or miscellaneous diseases (52.9%); 22 (3.1%) were hospitalized.

It appears that some military physicians use the civilian hospital emergency department as a surrogate for an out-patient specialty clinic and for x-ray and laboratory services. This is in contrast to the designated functions of the emergency department which are to provide emergency and trauma services and to evaluate the need for hospitalization of referred patients.

Deterioration of hepatic function following liver transplantation is a known complication, sometimes attributed to the use of cyclosporin A. Reaction to tacrolimus (Prograf), a relatively new and effective immunosuppressant drug, is thought to result in a much lower grade of organ dysfunction, especially in the transplanted liver.

Using the ex-vivo rat model of isolated perfused liver, we evaluated hepatocellular damage and oxygen extraction when tacrolimus was administered following liver hypoperfusion. Tacrolimus did not worsen hepatic dysfunction caused by the hypoperfusion. Therefore using tacrolimus in the perioperative period might be safer than cyclosporin A, which tends to worsen hepatic damage in the presence of hypoperfusion.

Patients with ischemic mitral insufficiency and poor left ventricular function are high operative risks. We present 101 patients who had mitral valve repair in our department: 21 had severely reduced left ventricular function, 19 were in NYHA functional Class IV, and 2 in Class III. All had concomitant coronary artery bypass.

There was no early operative mortality, but there were 2 late deaths (9.6%). At follow-up (3-36 months) all valves were functioning normally, 9 patients (43%) were in NYHA functional Class I, and 4 (19%) in Class II.

Our experience shows that repair of ischemic mitral insufficiency in the presence of severe left ventricular dysfunction can be performed with good results, and is preferable to mitral valve replacement. Late follow-up showed significant symptomatic improvement.

Effective use of modern therapeutic modalities results in the cure of 75%-80% of Hodgkin's disease patients, regardless of stage. The major threat to continued survival is, therefore, not recurrent disease but development of second malignancies. Recent reports have firmly established the increased risk of breast cancer developing in women treated with mantle field irradiation.

We describe 3 women who developed breast carcinoma following mantle field irradiation for Hodgkin's disease. Their clinical course was consistent with that reported in larger series. They were relatively young when irradiated and there was a long interval between radiation therapy and the diagnosis of breast cancer.

Review of the literature shows that there may be a role for prophylactic mastectomy after irradiation for Hodkgin's disease.

Coronary artery disease amenable to percutaneous interventions or coronary artery bypass grafting, and resectable lung cancer are major causes of morbidity and mortality. We present our experience in the treatment of 3 patients (men aged 64 and 66 and a woman of 77) who each had significant coronary artery disease and a resectable lung tumor. They underwent combined coronary artery bypass grafting and pulmonary lobectomy.

We conclude from our experience and review of the literature that concomitant surgery in such cases is safe and effective, decreases suffering, and decreases the cost of 2 separate invasive procedures.

Results of a 1996 survey of hospital pharmaceutical services in Israel are presented. A questionnaire was mailed to 46 pharmacy directors in Israel hospitals of which a total of 33 were returned (72%).

The main services provided at hospital pharmacies are production of pharmaceuticals and inventory management. The pharmacy directors estimated that more then half of their pharmacists' time was spent on technical work that did not need their academic, professional knowledge. In Israel general hospitals there are on the average 1.23 full time pharmacist positions per 100 hospital beds and 1.09 positions for other pharmacy employees.

A similar survey carried out in the United States showed an average of 7.4 pharmacists per 100 hospital beds. Pharmacists there have broad clinical roles which, in general Israeli pharmacists do not have.

Computer systems are used in our pharmacies mainly for inventory management. About half of the directors did not think that the location, structure and furnishings of their pharmacy were appropriate for its role.

Under current conditions, Israel hospital pharmacies are not organized to provide pharmaceutical services beyond inventory management and pharmaceutical production. Appropriate budgets and personnel are required to develop clinical pharmacy services at Israel hospitals. This would lead to improved quality of drug treatment and cost-containment and would allow pharmacists to exploit their knowledge, skills and training that under the current system, are only partially utilized.

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.

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.
