Background: Fibroadema, one of the most common benign breast lesions, has a characteristic age-specific incidence and is associated with other pathological entities in 50% of cases. The clinical or imaging diagnosis of fibroadenoma may be erroneous, and in some cases is found to be invasive cancer. The clustering of such entities, their correlation with age, and the risk of synchronous breast malignancy are uncertain.

Objective: To explore the possibility of any sigficant clustering of fibroadenoma-associated benign breast disease and to assess the possible risk of concomitant breast cancer.

Method: We analyzed the pathological results of 147 women undergoing excisional biopsies for fibroadenoma diagnosed pre-operatively either by clinical examination and imaging (n=117) or by radiology alone (n=30). The inter-relationships among all entities associated with fibroadenoma were studies by hierarchial cluster analysis. The correlation of the various pathologies with the risk of invasive breast cancer in relation to the patient’s age was also evaluated.

Results: Fibroadema-associated pathologies were found in 48% of the cases: sclerosing adenosis (23%), duct ectasia (17/7%), apocrine metaplasia (15.6%), florid fibrocystic disease (12.9%), duct papillomatosis (11.6%), infiltrating duct carcinoma (5.4%), duct carcinoma in situ (3.4%), and 1 case of lobular carcinoma in situ (0.6%). An orderly internal hierarchy and three significant clusters emerged: a) epithelial apocrine metaplasia, duct ectasia and sclerosing adenosis (similarity coefficients 16.0, 11.0 and 8.0 respectively); b) papillomatosis, florid fibrocystic disease and calcifications (similarity coefficients of 6.0, 4.0 and 2.0 respectively); and c) infiltrating duct carcinoma in situ (similarity coefficients of 1.8 and 1.6 respectively). Seven of the eight patients with breast cancer were older than 40 years.

Conclusions: In about half of the cases fibroadema was associated with other pathological entities clustered in an orderly hierarchy. The rarity of synchronous breast cancer in the younger age group and its more common association with fibroadema in the older age groups dictate a different approach to each. The finding of fibroadema in women older than 40 indicates the need for surgical excision.

 Background: Cigarette smoking has long beenregarded as an important factor in the pathogenesis of peptic ulcer disease.

Objective: To investigate whether cigarette smoking has an additive effect on the clinical presentation and course of disease in Helicobacter pylori-positive dyspeptic patients.

Patients and Methods: The study group comprised 596 consecutive H. pylori-positive dyspeptic patients (334 males and 262 females, mean age 50.6, range 12--81 years). Following upper gastrointestinal endoscopy, patients were subdivided by diagnosis as follows: Non-ulcer patient group (n=312: gastritis 193, duodenitis 119), gastric ulcer (n=19), and duodenal ulcer (n=265). H. pylori infection was confirmed by histology and/or rapid urease test. In addition, 244 patients had a positive 14C-urea breath test prior to antimicrobial treatment. The patients' medical history and smoking habits were obtained using a detailed questionnaire completed by the patients and their referring physicians.

Results: There were 337 non-smoking patients, 148 current smokers and 111 past smokers. Gastric and duodenal ulcers were significantly less prevalent in non-smokers than in current or past smokers (gastric 1.8%, 4.1%, 6.3%; duodenal 39.8%, 50%, 51.4%, respectively) (P0.05). The incidence of gastrointestinal bleeding was significantly lower in non-smokers than in current or past smokers (7.1%, 8.1% and 20.7%, respectively) (P0.05). Bacterial density, as assessed by the UBT value in 244 patients, was higher in non-smokers (mean 352.3273 units) than in past smokers (mean 320.8199) or current-smokers (mean 229.9162) (P0.05). Logistic regression analysis revealed that male gender, current smoking, and immigration from developing countries were all significant independent risks for developing duodenal ulcer, while only past smoking was associated with a higher rate of upper gastrointestinal bleeding in the past.

Conclusions: In H. pylori-positive dyspeptic patients, current smoking as well as male gender and immigration from developing countries are associated with an increased risk for duodenal ulcer. This effect does not seem to be related to the bacterial density or increased urease activity of H. pylori organisms.

Background: About one-third of patients with severe ulcerative colitis do not respond to conventional therapy and require urgent colectomy. It was recently shown that cyclosporin is effective in some of these patients.

Objectives: To review the current experience of six hospitals in central Israel that used cyc-losporin in patients with severe ulcerative colitis.

Methods: The files of all 32 patients treated with cyclosporin for corticosteroid-resistant ulcerative colitis were reviewed. Activity of disease was measured by a clinical activity, index colonoscopy and laboratory tests.

Results: The average duration of treatment with intravenous cyclosporin was 12.7 days (range 9–28) after which the disease activity index dropped from an average of 14.22 to 4.74. The mean time for response was 7.5 days (4–14). Twelve patients (40%) required surgery within 6 months and another 6 patients (18.8%) were operated on after more than 6 months. Twelve patients (37%) maintained remission for at least 6 months and did not require surgery. In one patient treatment was stopped because of non-compliance and one was lost to follow-up. There were numerous side effects, but in only one case with neurotoxicity was treatment withdrawn.

Conclusions: Cyclosporin is a relatively safe and effective treatment for severe ulcerative colitis. It induced long-term remission in 37% of the patients, and in those who required surgery the treatment resulted in an improved clinical condition before the operation.

Background: Trauma is the leading cause of death in children. In abdominal lesions the spleen is the most commonly involved organ. During the last two decades much effort has focused on spleen tissue conservation.

Objectives: To analyze the rationale of a multimodality management policy that includes autotransfusion and mesh wrapping.

Methods: Data gathered over 14 years illustrate the introduction of new techniques and their impact on cases of severe spleen rupture.

Results: A total of 122 children were treated during the 14 year period, 1985-98. In 16 children an absorbable mesh wrapping, alone or in combination with other techniques, was used to obtain hemostatis and save spleen tissue.

Conclusions: Mesh wrapping, partial splenectomy and autotransfusion can be used, alone or in combination, to preserve severely injured spleens. According to our records, all children survived with a functional spleen. There were no cases of rebleeding. In only one case of prolonged postoperative fever could the cause be traced to an infected spleen hematoma that was drained transcutaneously. Autotransfusion is performed simply and without the use of a "cell saver." Its use can be crucial in small or field hospitals or in a situation of mass casualty.
