Computed tomographic angiography (CTA) is a relatively new diagnostic modality in the field of vascular surgery. Despite being new it has already been introduced into a wide range of diagnostic applications in this field and in many cases it can precede or replace the conventional intra-arterial angiography. During a 12 month period between 1.8.98 and 1.8.99 sixty five peripheral arterial imaging scans were performed using a CT Twin - 2 helical scanner (Spiral Twin Flash., Elscint, Israel) with a 100% technical success rate and no complications at all. Twelve patients (18.5%) were operated upon and 20 (30.7%) underwent endovascular procedures with full intra-procedural agreement with the pre-operative or pre-procedure CTA findings. Despite possible pitfalls and a few disadvantages the technique carries major benefits and significant advantages to both the patient and the clinician. Therefore we recommend considering CTA as a first line diagnostic modality whenever peripheral vasculature has to be demonstrated whether electively or urgently and to spare the conventional angiography for selected cases only.

In order to determine a policy within the hospital restricting smoking we previously surveyed the attitude of the hospital staff towards smoking inside the hospital buildings. In the present survey we examined the attitude of the hospital visitors on the same issue. One hundred and fifty-seven hospital visitors participated in the survey and answered a questionnaire; 93 visitors were smokers, 64 were non-smokers.

Eighty-eighth percent of the visitors smoked during their visit, 4 cigarettes on the average, during an average length of stay of 2.8 hours, until completing the questionnaire. Eighty-three percent of the smokers were aware of the law that prohibits smoking in public buildings, and 71% were aware of the signs and advertisements that prohibit smoking in the hospital. Two thirds of the smokers declared that they would have refrained from smoking in the hospital if others around them also refrained from smoking and justified the law that prohibits smoking in public buildings, including hospitals. Sixty-nine percent of the smokers declared that they were willing to cooperate with hospital management in restricting smoking to the hospital grounds outside the hospital buildings, and would accept directives regarding smoking restriction from any hospital personnel. In fact, only 11% of the smokers were requested to stop smoking during their visit.

These findings reinforce the results of our pervious survey conducted among the hospital staff and indicates the existence of a paradoxical vicious cycle of behavior among smokers and non-smokers, visitors and staff, in the hospital. On the one hand the smokers do not have the self-obedience necessary to stop smoking while visiting in the hospital, although they are aware of their misdeed. On the other hand the non-smokers lack the confidence that they will obtain the cooperation of the smokers, although the smokers are willing to cooperate. Both groups expect someone else to either actively restrict them from smoking or to encourage them to restrict the smokers.

Our findings suggest that this “someone else” is the hospital management (and the staff endorsed to implement this directive).

Resection presents the only possible cure for pancreatic cancer. An aggressive surgical approach may extend the limits of resection and offer cure for more patients. 37 women and 28 men, mean age 67 years (range 33-84) with focal lesions underwent pancreatic resection (1993-1999). Cancer of the pancreatic head was found in 45, in the ampulla in 4 and in the body or tail in 16. There was a tumor larger than 5 cm in 9, vascular involvement in 8, and a combination of both in 6.

All were evaluated prior to exploration by standard imaging techniques and 44 by laparoscopic ultrasound. 42 underwent pancreatico-duodenectomy, 16 distal subtotal pancreatectomy and 3 local excision of an ampullary tumor. Benign lesions were found in 8 (focal pancreatitis in 4 and a serous cystic lesion in 4).

Curative resection (microscopically negative margins, negative lymph nodes) was achieved in 44. 2 died 1-2 months after operation of septic complications (2% operative mortality). The most frequent complication (in 8) was pancreatic fistula. Additional complications included anastomotic-line bleeding (3), intra-abdominal abscess (2), and 1 developed portal vein thrombosis (treated surgically).

1- and 2-year survival in those after curative pancreatic resection was 81% and 55% respectively. 2-year survival in those after palliative resection (positive resection margins or positive lymph nodes) was 50% and 11%, respectively.

After proper selection of those in whom it is possible to perform curative resection, regardless of size or vascular involvement, an aggressive surgical approach is justified.

Prostatic cancer (PC) is second only to lung cancer as a cause of cancer mortality in men word-wide. In Israel it is the most common cause of cancer mortality in men, after lung cancer and colo-rectal cancer.

We screened, for the first time in Israel, for prostatic cancer using serum levels of PSA and a digital rectal examination (DRE). The purpose was not only to diagnose PC but also to increase public awareness of the condition.

300 men in the Haifa area who met statistical criteria for early diagnosis of PC participated. They filled a questionnaire regarding risk factors for PC (age, family history (FH) of prostatic and breast cancer, cigarette smoking, alcohol consumption, previous PSA sampling) and were examined. Those who had out-of-ragne, age-related PSA values, or a pathologic DRE underwent trans-rectal ultrasound (TRUS) examination and guided biopsy of the prostate. Those with a positive biopsy for PC underwent radical prostatectomy or radiation therapy.

41 (14.3%) had out-of-range, age-related PSA levels and 10 (3.5%) had a pathologic DRE. 39 (13.3%) underwent TRUS and biopsy and 6 (2.04%) had clinically significant PC, all early stages (Gleason 4-6).

Correlation between age and PSA has been proven statistically significant (p<0.05). Symptoms of urinary tract obstruction and nocturia were related to a high PSA (p=0.035 and 0.002, respectively). Those with PC had at least 1 symptom of urinary tract obstruction; 6 (15.3%) who underwent TRUS and biopsy and a FH of prostate cancer. However, no subject with a FH of PC had biopsy-proven cancer. Those with PC had PSA values from 4.9 to 31.8 ng/ml (9.6 median). Age-related PSA had a positive predictive value of 17.1%.

Results of our annual screening for early detection of PC using age-related PSA, and DRE are encouraging: cases detected were clinically significant and treatable. It would appear that screening for PC will result in decreasing the incidence of metastatic cancer and therefore mortality.

Hand-in-hand with the public's growing interest in health care, there has been an increasing demand for natural health products considered both safe and medically effective. But many such products have not been shown to meet efficacy and safety criteria and therefore can not be registered as pharmaceuticals. On the other hand, it is quite clear that some products do have pharmacological activity and are being used for therapeutic or preventive effects.

In Israel, the marketing rules for food or dietary supplements prevent their manufacturers from claiming medicinal/healing properties that the product might have, and allow only limited health statements. But great demand for these products has created massive publication attributing medicinal indications for products whose quality, efficacy and safety have neither been examined nor proven according to accepted medical criteria.

We review the regulation and supervision of natural health products in Israel and other developed countries and find a broad range of opinions about natural health products. They range from acceptance as conventional drugs reimbursable by the health insurance, as in Switzerland and Germany, to their status as dietary supplements requiring no significant authorization or supervision, as in the USA.

Analysis of the current situation in Israel and the western world would indicate that some natural health products do possess pharmacological activity and therefore manufacturers should be allowed to make limited claims for specified therapeutic properties. A stricter set of registration regulations are needed for proof of safety, efficacy and quality of these products, but more lenient than those for registering a pharmaceutical product.

Thrombocytopenic purpura associated with brucellosis has rarely been described in children. The thrombocytopenic purpura is usually part of the array of manifestations of brucellosis, such as fever, malaise, arthralgia, arthritis, hepatosplenomegaly and lymphadenopathy.

We describe a 4-year-old girl in whom severe thrombocytopenic purpura was the only manifestation of brucellosis which resolved after appropriate antibiotic therapy. We conclude that brucellosis should be included in the differential diagnosis of thrombocytopenic purpura in areas endemic for brucellosis, and when there is a history of exposure to infected food products.

Various plants induce dermatitis in man. There have been only a few published cases of contact dermatitis caused by Agave americana (AA).

We report intentional exposure to AA in a soldier seeking sick leave, and review our previously reported cases. Treatment with oral antihistamines and topical saline compresses resulted in subsidence of the systemic symptoms within 24h and regression of cutaneous manifestations in 7-10 days.

Physicians should be alert to the possibility of self-inflicted contact dermatitis induced by exposure to plants, especially to A. americana. Systemic signs may accompany the cutaneous lesions.

The use of albumin has been a matter of debate since its introduction in the 1940's. Albumin is not only expensive but may also be harmful when administered inappropriately. Until recently our use of albumin was controlled by a number of authorized physicians who signed all albumin prescriptions.

In August 1998, a multidisciplinary team reviewed the indications for albumin use and introduced simple guidelines for its supply and administration. As a result, the use of albumin has decreased by almost 70%. This indicates that rational use of albumin can be achieved by appropriate guidelines, without requiring administrative limitations. We believe that this conclusion holds true for other diagnostic and therapeutic procedures as well.

The femoral artery remains the most used peripheral site for radiological catheter access. With a greater number of both diagnostic and therapeutic procedures being performed by interventional radiologists and cardiologists, and with larger catheters being used for stenting and endovascular grafting, the incidence of iatrogenic pseudo-aneurysms reported has reached as high as 0.5-2%. Ideally, they should thrombose spontaneously. However, when this does not occur, management options include: observation, ultrasound-guided obliterative compression, direct thrombin injection, embolization, stent graft insertion, and very rarely- surgery.

During a 7-year period (1992-1999) we treated 131 cases of femoral artery false aneurysms. Until 1998 ultrasound-guided compression-obliteration, with a 95% success rate, was our method of choice. Since 1998, direct thrombin injection, with 100% success in 24 cases, has become our preferred method. It is pain-free, fully successful even in anticoagulated patients, and is currently our treatment of choice.

The use of testicular spermatozoa for intracytoplasmic sperm injection introduced a new treatment modality for management of male infertility.

Since testicular biopsies of non-obstructive azoospermic men are not homogenous in their histological patterns, identification with certainty of focal spermatogenesis might be difficult, particularly in those with small foci of spermatogenesis. We used an immunohistochemical marker of the male germ line, an antibody generated against RBM (RNA-binding-motif), to recognize with high precision the presence of germ cells in the biopsy. Biopsies of 30 men with azoospermia, most with non-obstructive azoospermia and a few with obstruction of the vas deferens, were evaluated.

Immunohistochemical staining for RBM protein contributed to the detection and accuracy of the identification of germ cells. Furthermore, this immunohistochemical technique aided the histopathologist to focus on even small foci of spermatogenesis. Absence of the protein expression confirmed the diagnosis of Sertoli-cell-only syndrome. The results indicate that expression of RBM can be a diagnostic marker for identifying the germ cells of small concentrations of spermatogenesis. This method can enhance the accuracy of histopathological evaluation of testicular biopsies that had formerly relied mainly on hematoxylin-and-eosin staining.

High dose chemotherapy and autologous stem cell transplantation are widely used in relapsed and primary refractory Hodgkin's disease. We transplanted 42 patients with Hodgkin's disease between 1990-1998. Median follow-up was 31 months (range 1-102). 29 (69%) were transplanted after relapse and 13 (31%) were refractory to first line therapy. Median age at transplantation was 29 years (range 19-58) and 23 (55%) were males.

All were treated with the BEAM protocol (carmustine, etoposide, cytarabine and melphelan). 18 who were in remission received radiotherapy following transplantation. The source of the stem cells was bone marrow in 17% and peripheral blood in 83%. At initial diagnosis: 57% had stage III-IV disease and B symptoms were present in 52%. 75% were treated with MOPP, ABVD or with related versions. Radiotherapy followed in 52%. Prior to transplantation, 45% of the relapsed group were in the advanced stage. 33% and 12% of all patients had lung and bone involvement, respectively.

The complete remission rate was 86% for the 2 groups. 2 (5%) died from transplant-related complications and MDS/AML developed in 2 (5%) after transplantation. The 3-year overall survival (OS) and disease-free survival (DFS) were 68% and 60%, respectively. The 3-year OS for the relapsed group was 64% compared with 76% for the refractory group, and the 3-year DFS for the relapsed group was 60% vs. 42% for the refractory group (neither difference significant). Radiotherapy following transplantation did not have a beneficial effect on DFS. No prognostic factors for outcome of transplantation were found, most probably due to the limited number of patients and the high variability of disease characteristics.

We conclude that high dose chemotherapy and autologous stem cell transplantation are effective and relatively safe for relapsed or primary refractory Hodgkin's disease. The DFS at 3 years was longer for those transplanted after relapse than those with primary refractory disease, but not significantly. Patients with primary refractory disease can be salvaged with high dose chemotherapy.
