Surgery Dept., Soroka University Hospital, Beer Sheba

Arterio-venous fistula is a relatively rare form of vascular injury. A cof an unusual fistula between aorta and inferior vena cava is presented. Occasionally this type of is difficult to diagnose early. Life-threatening conditions may mandate prompt treatment and the use of damage control strategy. It is also important to diagnose and treat this injury in order to prevent complications. Sudden hemorrhage and congestive heart failure are the major disturbances that result from aortocaval fistula.

The results of properitoneal mesh repair of inguinal hernia were evaluated in 38 of 43 consecutive patients operated by Stoppa's technique. In 33 patients the hernia was bilateral and in 10 unilateral; in 20 it was recurrent. In 33/43 patients the mesh was fixed either by sutures or metal clips. The overall recurrence rate after 22 (14-36) months of follow-up, was 10.5%. This result was composed of a 3.0% recurrence rate in the fixated-mesh group, and 30.0% among those with non-fixated mesh.

The outcome following the Stoppa method for tension-free properitoneal mesh repair of inguinal hernia, compares favorably with those of other methods, provided proper attention is paid to adequate mesh placement and fixation. Further prospective studies are needed to define the role and indications for this technique in the laparoscopic era.

Our objective was to assess the functional disability of stroke patients by the functional independence measure (FIM) and to examine predictive factors for successful rehabilitation. In 127 consecutive stroke patients efficacy of FIM was 23.9±188, efficiency 0.54±0.45 and 81.9% of patients returned home. Functional improvement was statistically significant (p<0.001) in all FIM domains. Multivariate analysis showed that improvement in FIM score was significantly greater in the younger, among the married, the hemiparetic, and those with an admission FIM of 40-60, while efficiency was related only to type of diagnosis. In addition, the hemiparetic were 3.3 times more likely to return home than the hemiplegic.

We conclude that rehabilitation priorities should be directed towards patients younger than 75 years and to those with an admission FIM of 40-60 points. The results of this study reaffirm the usefulness of the FIM index in assessing stroke rehabilitation.

Carotid sinus syndrome is a well-recognized cause of unexplained syncope in older patients, and may lead to significant morbidity due to trauma from falls. Dual chamber pacing has been shown to be effective in relieving symptoms due to bradycardia, but not due to vasodepressor response. We report an 84-year-old man with recurrent syncope due to carotid sinus hypersensitivity. He was treated only with a serotonin re-uptake inhibitor and was symptom-free after 3 weeks of therapy. He has remained symptom-free for the past year.

Willingness to Donate Organs: Attitude Survey among Israeli Jews

A public opinion survey of Israeli Jewish adults (September) showed a large potential willingness to donate organs after death, while only a third of the sample was opposed. Nevertheless, only a very minor proportion held donor's cards, and over half expressed opposition to holding a donor card. As to next-of-kin's organs, when the wishes of the relative were not known, a quarter of the sample opposed, a quarter agreed, and the remaining half hesitated to make a decision.

Willingness to donate was not correlated with gender, age or income, but was related to religiosity: the more religious, the less willing to donate. And the religious reason was the salient one given for hesitation about donating, although there were many who could give no reason for their hesitation. Family members, doctors and rabbis (in ascending order) influenced willingness to consent to next-of-kin donations.

Marked obesity is an independent risk factor for multisystem morbidity. The use of anorectic drugs is an aggressive strategy for weight reduction. It appears to be an easy way of dealing with the problem, because the patient needn't change his behavior. However, such treatment is not harmless. At the end of the 60's an outbreak of pulmonary hypertension was associated with the drug aminorex, and it was soon withdrawn from the market. 30 years later it became clear that new-generation anorectic drugs (fenfluramine, dexfenfluramine, phentermine), which were being used world-wide, lead to both pulmonary hypertension and valvular damage.

We describe a woman of 70 with both these complications which developed after prolonged anorectic therapy with a fenfluramine-phentermine combination.

Kaleidoscopic Autoimmunity

We describe an 18-year-old girl with idiopathic thrombocytopenic purpura (ITP) who developed chronic active hepatitis following splenectomy that cured the ITP. This is a phenomenon in which an organ belonging to the immune system is resected, which results in cure of one autoimmune disease but in the emergence of another, apparently unrelated, second autoimmune disease. We refer to this phenomenon as kaleidoscopic autoimmunity, explaining that some autoimmune diseases are not induced by autoantigen-driven mechanisms, but rather result from immune dysregulation.

Primary health care physicians have a pivotal role in treating mental health problems. We determined the proportion of primary care physicians in Israel who treat depression and their characteristics. The study was based on a stratified national random sample of primary care physicians (n677, response rate 78%). From these physicians' reports 22% always treat depression, 36.6% usually, 28.6% sometimes, and 12.6% never. Based on a logistic regression model the physicians who always or usually treated depression were distinguished from the other physicians by their treating more medical conditions on their own, seeing themselves as having more first contact for psychosocial problems, having frequent contact with social workers and specializing in family medicine. Primary health care physicians play a major role in treating depression on their own. This raises new questions about how they treat depression themselves, and under what circumstances they treat or refer to a specialist.

From 1989 to 1996, 139 cases of invasive Hemophilus influenzae B (Hib) infections were identified in children in the Negev, 110 of which occurred before introduction of the conjugate vaccine (1989-92). At that time there were 60.5 cases of Hib per 100,000 in the Negev among children under 5 years of age. During 1995-1996, when Hib conjugate vaccine was part of the regular immunization program, Hib decreased to 6.5 cases per 100,000 in that age group. The effectiveness of PRP-OMP vaccine was 96.5% among Jews and 89% among Bedouins, and the efficacy of the immunization program was 99.99%. This degree of success exceeded all expectations based on the literature. During the whole study period, Hib infections were more frequent among Bedouins than Jews. There was no significant difference in the occurrence of Hib among Jews in the Negev before and after the vaccine was introduced. Hib among Bedouins in the Negev was significantly more frequent than in the Israeli population as a whole before the vaccine was introduced. That gap narrowed after the vaccine was introduced because of the decrease in morbidity among the 2 groups.

Follicle-stimulating hormone (FSH) is considered to be the most important plasma hormone correlated with spermatogenesis. Elevated FSH plasma levels were shown to be associated with complete damage to testicular seminiferous tubule germinal epithelium. Recently, there have been conflicting reports with regard to the value of FSH plasma levels in predicting seminiferous tubule histology in the azoospermic patient and hence, as a guide for therapy in assisted reproduction using testicular sperm retrieval. The aim of this study was to evaluate whether FSH plasma levels can predict spermatogenic pattern in the testes of the azoospermic infertile patient. 69 infertile men with non-obstructive azoospermia and 18 with very severe oligospermia were studied. In all, plasma levels of testosterone, free testosterone, prolactin, luteinizing hormone and follicle-stimulating hormone were measured by enzyme immunoassay. In the azoospermic patients the seminiferous tubule spermatogenic pattern was determined in testicular aspirates obtained by multiple fine needle aspiration and categorized according to the most mature spermatogenic cell type in the aspirates: Sertoli cells only, spermatogenic maturation arrest or full spermatogenesis. There were no significant differences in plasma levels of any hormone measured except in very severely oligospermic and azoospermic patients. Both normal and elevated levels were detected in all, regardless of seminiferous tubule cytological pattern or plasma FSH in azoospermic patients. It is concluded that plasma levels of FSH can not be used as a predictive parameter, neither for the presence of spermatozoa nor for any other seminiferous tubule cytological pattern in azoospermic infertile men. They cannot serve as guides for selection of azoospermic men for trials of testicular sperm retrieval in assisted reproduction.

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.

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.

Intravenous injection of lignocaine relieves pain in animals with experimentally induced pain, and in man, mainly those with neuropathic pain. 106 patients were treated with intravenous lignocaine during a period of 18 months (212 treatment sessions). Blood pressure, heart rate and pain scores were continuously monitored after an intravenous bolus of lignocaine, 1 mg/kg, followed by continuous infusion of lignocaine, 5 mg/kg during 1 hour. There was significant pain relief after each session in most patients, lasting from a few hours to 4 weeks. There were no significant side effects. We present 2 of our patients. Due to its simplicity, efficacy and safety, intravenous lignocaine injection is recommended for those with neuropathic pain unrelieved by other therapeutic modalities.

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.

There is inherited predisposition to breast and ovarian cancer in 5-10% of all women with these diseases. Germline mutations in BRCA1 and BRCA2 presumably account for most of the genetically susceptible individuals. We summarize 2 years of experience in counseling and testing for inherited predisposition to these cancers.

597 women (from 320 families) have been evaluated since August 1995. 242 were evaluated for inherited predisposition to breast and ovarian cancer. One-third had clear-cut evidence of familial background. 74 families were of Ashkenazi origin; the age range of breast cancer was 30-35, of ovarian cancer 40-45. In 80% of families other cancers were also noted in first degree family members, including lung, colon, and prostate cancer and leukemia.

Genetic testing revealed that 45% of affected and 25% of unaffected women were carriers of a mutation in BRCA1 or BRCA2: 67/90 185delAG (BRCA1), 12/90 6174delT (BRCA2), and 4/90 of 5382insC (BRCA1). In addition, a novel mutation in exon 11 of BRCA1 was detected, carried by 7/90 women. The experience gained in oncogenetic counseling and genetic testing for inherited cancer predisposition will eventually enable determining an optimal, rational therapeutic regimen in carriers of mutations.
