Gastric leiomyosarcoma (GLMS) is a malignant, smooth muscle neoplasm accounting for not more than 0.45%-3.5% of primary gastric malignancies and 17%-20% of all smooth muscle tumors of the stomach. A well-chavariant has been variously referred to as leiomyoblastoma and epithelioid leiomyosarcoma. Because of the rarity of GLMS, few authors have tried to correlate clinical presentation, pathological findings, and treatment. There is no uniform therapeutic approach for leiomyosarcoma of the stomach and reported survival rates vary widely. We present a 56-year-old man whom we treated for this condition.

Diaphragmatic hernias in adults that are not categorized as hiatal hernias are rare. Hernias of the diaphragm itself appear in the perinatal age group and are defined as congenital hernias, presenting with severe respiratory distress and requiring immediate repair. There are a few asymptomatic postpartum cases in young children or adults.

We present 3 cases of diaphragmatic hernia in men, aged 19, 20 and 74, respectively. 2 were admitted because of colonic incarceration with strangulation in the hernial sac. In the other case there was an incidental finding of incarcerated colon in a diaphragmatic hernia discovered in a patient who initially presented with unrelated thoraco-abdominal trauma. Contrary to the dominant clinical presentation as infant-respiratory distress, the predominant findings in adults are gastrointestinal complications.

We believe successful treatment is more likely when there is a high level of awareness of the possibility of this kind of hernia in the adult, which can be a recurrence after perinatal hernia repair. It is essential to recognize that this is a combined thoraco-abdominal problem since it is often necessary to perform simultaneous laparotomy, thoracotomy and stoma formation.

Interest in, and use of alternative medicine has increased in the past few years in Israel. Still, little is known about the extent to which it is utilized, the more common treatments, patterns of use, and its influence on the conventional primary care system. We surveyed a kibbutz community to determine prevalence and patterns of use of alternative medicine and satisfaction with the outcome. The entire kibbutz population was asked to fill out a questionnaire (parents answered for their children). They were questioned as to their use of alternative medicine in the previous 5 years, types and dates of treatment, duration of treatment, and whether it had helped.

Of 1044 subjects, 830 responded (79.5%). 16.4% had used alternative medicine at least once in the previous 5 years. Of these, more than a 1/4 were treated by 2 or more types of alternative therapy. About 2/3 of those responding were women. Most had muscle-skeletal (36%), upper respiratory and/or atopic problems (19.3%). The most common treatments were homeopathy (31%) and acupuncture (20%). In approximately 2/3, the treatment was considered helpful, and either solved the problems or gave long-lasting improvement. 70% of those who used alternative medicine were treated within the previous 15 months and about 40% within the previous 3 months. The use of alternative medicine is increasing and it is now includein standard medical services. Most of those who used alternative therapy felt is hadhelped.

6 cases of popliteal vascular trauma are presented, 3 due to posterior dislocation of the knee and 3 due to crush injury. The patients were referred from another hospital and some had undergone unnecessary angiography when ischemia was present, leading to delay in surgery. All patients presented with distal ischemia and underwent reconstructive surgery; 2 subsequently underwent below-knee amputation because of irreversible ischemia and sepsis.

Urgent operation for popliteal vascular trauma is necessary whenever there is ischemia and intraoperative angiography may be necessary. There should be reconstruction of the artery and vein when there is concomitant venous damage, and fasciotomy and debridement are important. The harmful potential of occult popliteal vascular injuries and their ostensible mild presentation present a challengfor the emergency room surgeon.

Mechanism of Primary Hypertension

We review various theories of the pathogenetic mechanisms of steroid-induced and essential hypertension. We investigated the possibility that a pathogenetic mechanism leading to glucocorticoid (GC)-induced hypertension or to mineralocorticoid (MC)-induced hypertension, or both, may be of critical importance in primary hypertension. We studied plasma levels of corticosterone (BK) and aldosterone (Aldo), and their concentrations in arterial and renal tissues of spontaneously hypertensive rats (SHR), a model of primary hypertension, and in the antecedent strain WKY rats as a normotensive control. Plasma levels of BK and Aldo were found to be normal and identical in SHRs and WKYs. Tissue (intracellular) levels of BK were more than double in SHRs than in WKYs. Subsequently we examined the activity of 11b-hydroxy steroid dehydrogenase (11-HSD) in both aortic and renal tissues of SHRs and WKYs. 11-HSD converts BK to the corresponding 11-keto compound, 11-dehydro-corticosterone (cpd.AK), which is inactive, in view of its inability to bind to the MC receptors (and also to the GC receptors). BK, the main glucocorticoid in the rat, as well as cortisol, have high affinity for the MC-receptor (MR). Normally BK or cortisol are present in 10²-10³ times greater concentrations than Aldo in tissues possessing MR. The enzyme 11-HSD deactivates BK (or cortisol), thus protecting MC-receptors in the MC target tissues from being activated by GC. When we examined arterial and renal tissue activities of 11-HSD in SHRs, the activity of 11-HSD was only one-third that found in the WKY rats. This explained higher levels of BK in the tissues of SHR, and suggested that decreased activity of 11-HSD is a pathogenetic factor for hypertension in SHRs.

Thus, in a model of primary hypertension such as SHR, decreased activity of 11-HSD in the target tissues of MC appears to lead to glucocorticoid-induced mineralocorticoid hypertension.

Cryosurgery is an old technique which is being used for hepatic tumors as an adjuvant to hepatic resection. We recently treated 7 patients with multiple malignant liver tumors, 5 of whom had colorectal metastases, 1 carcinoid metastases, and 1 multiple hepatic lesions of hepatocellular carcinoma. 6 underwent combined liver resection and cryoablation of lesions in the remaining liver. In the 7th patient, only cryoablation was performed because hepatic resection was rejected and there was an extrahepatic metastasis. The advantages of this treatment are removal or destruction of all liver lesions found by any method, including intraoperative ultrasound examination, maximal preservation of normal liver parenchyma and that it is curative in patients inoperable by standard criteria.

Fracture of the talus, which articulates with 4 other bones in the ankle and foot, must be properly diagnosed, classified and treated to avoid the common complications of post-traumatic osteoarthritis and avascular necrosis. Knowledge of blood supply and anatomy is imperative, since the surgical approach must not damage the few vascular structures that remain intact after the trauma. We present 5 cases of fractures at the neck of the talus. All underwent internal fixation, 1 after closed reduction and 4 after open reduction. In all the results were satisfactory, although 1 patient developed avascular necrosis of the talar body.

We report a 48-year-old man admitted for watery diarrhea, high fever, chills and abdominal cramps. Entero-hemorrhagic E. coli O157:H7 was isolated. This new, dangerous pathogen causes dysentery and complications such as hemolytic uremic syndrome and thrombotic thrombo-cytopenic purpura. These complications can cause renal failure, neurological deficit and death. Recognition of E. coli O157:H7 infection is important since it causes a rare and dangerous condition. To the best of our knowledge this is the first case reported in Israel.

Malignant bowel obstruction occurs in about 10% of those with advanced abdominal cancer and in about 25% of those with advanced pelvic cancer. Such patients usually develop nausea, vomiting, constipation, abdominal dilatation and colicky pain. Traditional therapy consists of intravenous fluids and decompression by duodenal tube, gastrostomy or operation but postoperative mortality is high. Treatment requires hospitalization and therefor such patients have not been considered candidates for home care.

Palliative medical techniques can cope with this syndrome and allow home care. Hypodermoclysis, non-prokinetic anti-emetics like haloperidol and scopolamine, octeotride, corticosteroids, and narcotics for severe abdominal pain can alleviate symptoms. Medications can be combined and infused subcutaneously in a syringe driver and patients can remain with their families in their natural environment. Such techniques can give these patients who have short life expectancies reasonable quality of life.

Use of Intranet in the Hospital Setting

College of Administration, Tel Aviv and Rambam Medical Center, Haifa

In the Intranet system, the organization uses technologies developed and applied in the Internet network world-wide. Hospitals can use Internet technologies to make hospital information systems more efficient by improving use of existing systems and by adding additional possibilities. Furthermore, the hospital can improve its relations with its customers and also bring the organization additional customers. Intranet implementation can be divided into the areas of: communication, managing and distributing information, and application linkage. Implementation must be modular, gradual and planned according to economic, technological and organizational aspects of the hospitals. By the Intranet, organizations can achieve benefits that include: improving communication array, availability of data and information, using existing information systems and their applications, enhancing customer satisfaction and saving costs of manual application systems.

The dramatic course of necrotizing soft tissue infection represents a medical emergency, since it is limb - and life-threatening. Most necrotizing soft tissue infections are caused by mixed aerobic and anaerobic Gram-negative and Gram-positive organisms. Most case have been reported in immunocompromised hosts after penetrating trauma or surgery. We describe a unique series of cases of necrotizing soft tissue infection. The mainstay of treatment is early and daily debridement of devitalized tissue and broad-spectrum antibiotics. Hyperbaric oxygen therapy should be considered.

Conversion Total Hip Replaceafter Failed Internal Fixation of Intertrochantric Fracture

Dept. of Orthopedic Surgery, Carmel Medical Center, Haifa

Between 1933-1995, 16 patients underwent conversion-total hip replacement after internal fixation of an intertrochanteric fracture failed. Clinical results were unsatisfactory compared to primary total hip replacement. There was a high incidence of intra- and postoperative complications, including femoral fracture, wound infection, and aseptic loosening. This study should increase the surgeon's awareness of the difficulties encountered in conversion of failed intertrochanteric fractures to total hip replacement.

Polyunsaturated fatty acids (PUFA) are vital for the normal development of the brain and the eye retina in infancy. Breast milk contains significant amounts of PUFA, and compensates for their low production in infancy. Only recently a few companies with worldwide product distribution have started to enrich infant formula with PUFA. We evaluated the safety and clinical efficacy of a locally made PUFA-enriched infant formula, produced for the first time in Israel.

50 normal, full term infants participated in a prospective, randomized double-blind study. Half received a regular whey-predominant infant formula (Materna Plus), and the other half a PUFA-enriched formula (Materna Premium), both produced in Israel, for 30 days. Evaluation included physical examination, growth parameters, stool analysis, daily parental questionnaires regarding infant behavior and defecation, and developmental assessment.

There were no significant differences on comparing growth parameters, infant behavior, attacks of restlessness, gas severity, or stool characteristics in the 2 groups. There were no side effects or abnormal stool findings in either group, and no differences in developmental assessment at 3 months of age.

We conclude that the locally-produced PUFA-enriched infant formula is safe and clinically efficient. We assume that the lack of any effect on developmental indices is due to the relatively short exposure to the PUFA-enriched diet. Nevertheless, based on the recent literature, there is no doubt that PUFA supplementation isvital in improving infant brain and eye development.

A prospective study was carried out among elderly patients with community-acquired pneumonia to determine if there are any specific features that could help in deciding whether to hospitalize, or to treat in the community. We concluded that there is no correlation between clinical presentation of pneumonia and outcome, except for impairment of consciousness. Laboratory data showed a correlation between oxygen saturation in arterial blood, levels of hemoglobin and albumin, and outcome. Sputum culture was not helpful in deciding about diagnosis and treatment, which remain empiric. These patients should be treated at home if conditions permit. Recommendations are made for improving such conditions.

Cyclic vomiting syndrome in children is a manifestation of various etiologies, including gastroenterological and renal disorders, central and autonomic nervous system abnormalities, as well as metabolic and endocrine dysfunction. Frequently no organic cause is found. Personality profiles of children with cyclic vomiting reveal perfectionism, competitiveness, and aggressive behavior. Vomiting attacks have been induced by anxiety and excitement in patients with cyclic vomiting. We describe an 8-year-old girl with cyclic vomiting, frequently associated with occipital headaches, photophobia or dizziness. Psychiatric evaluation indicated a generalized anxiety disorder.
