Objectives: To describe the role of wireless capsule endoscopy in diagnosing isolated small intestinal Crohn’s disease in two adolescents.

Methods: Wireless capsule endoscopy was performed in two adolescents with severe protein-losing enteropathy and negative standard diagnostic workup.

Results: Wireless capsule endoscopy successfully diagnosed Crohn’s disease with uncharacteristic presentations and negative radiographic and endoscopic findings in both patients.

Conclusions: The non-invasiveness and ease in performance of capsule endoscopy on an ambulatory basis make this diagnostic modality especially advantageous for children.

Background: An estimated 10% of all children are subject to recurrent attacks of abdominal pain of unknown origin. When no organic cause is found, the working diagnosis is usually functional abdominal pain.

Objectives: To investigate the possible causative role of occult constipation.

Methods: We defined occult constipation as the absence of complaints of constipation on initial medical history or of symptoms to indicate the presence of constipation. The diagnosis was made by rectal examination and/or plain abdominal X-ray.

Results: Occult constipation was found to be the cause of RAP[1] in 42.6% of children examined. Treatment consisted of paraffin oil and phosphate enema. In 82.84% of cases the abdominal pain subsided considerably or disappeared within 2 weeks to 3 months of treatment. On telephone interview of the parents at 1–1.5 years after discharge, 96.5% reported that both the abdominal pain and constipation had subsided or disappeared.

Conclusions: Occult constipation can be easily identified and treated in a large number of children with RAP who were diagnosed as having functional abdominal pain.

Background: The long-standing and ongoing controversy regarding administration of analgesia to patients with acute abdominal pain prior to final diagnosis has not yet been resolved, despite considerable research. Consequently, wide variations in clinical practice exist.

Objectives: To determine the motives, attitudes and practices of emergency physicians, internists and surgeons in Israeli emergency departments regarding the administration of analgesia before diagnosis in patients with acute abdominal pain.

Methods: Questionnaires were completed by 122 physicians in 21 EDs[1] throughout Israel and the replies were analyzed.

Results: Most EDs did not have a clear policy on analgesia for undifferentiated abdominal pain, according to 65% of the responders. More internists (75%) than surgeons (54%) (P = 0.02) and more emergency physicians (81%) than all other physicians (60%) (P = 0.05) held this opinion. Most respondents (64%) supported administration of analgesia pre-diagnostically. Support for analgesia was significantly stronger among internists (75%) compared to surgeons (52%) (P = 0.03). Despite this wide support, most respondents (68%) indicated that analgesia was rarely or never given pre‑diagnostically and, when it was, more surgeons (58%) than other physicians made that decision. Most internists (73%) and all surgeons reported that patients receive analgesia only after being examined by surgeons. Time allocated to the ED (part‑ or full‑time) significantly (P = 0.02) influenced decision-making, with 51% of part-time physicians vs. 25% of full-time opposing prompt administration of analgesia. Opinions on who should decide were divided according to medical specialty, with surgeons and internists almost opposed, as well as by physician age and percent of his/her time spent working in the ED. More surgeons than internists (P = 0.0005) reported that analgesia sometimes interfered with making a diagnosis. Most physicians (90%) stated that opiates impede diagnosis, to some extent. However, 58% of them supported the administration of opiates, more or less frequently. Intramuscular diclofenac was the most preferred analgesic, followed by intravenous morphine and pethidine; individual preferences extended beyond the list of actually administered drugs.

Conclusions: There is no consensus on the administration of analgesia for undiagnosed acute abdominal pain in EDs in Israel. Physicians’ attitudes are influenced by training, experience, and percent of personal time allocated to work in the ED.

Background: Arterial involvement in Behçet's syndrome is rare. Aneurysms are common among the arterial lesions, affecting various arteries but mostly the abdominal aorta. Surgical interposition graft insertion is the treatment of choice for large aneurysms. However, vasculitis in these patients is the reason for the notorious surgical complications that result in up to 50% false aneurysms in anastomotic sites. Recently, endovascular repair for abdominal aortic aneurysms has been established.

Objectives: To learn more about vascular Behçet and, specifically, to compare the results of surgical treatment and endovascular repair of AAA[1] in patients with Behçet's syndrome.

Methods: We retrieved the medical records of all 53 patients with Behçet disease admitted to Rambam Medical Center during the years 1985 and 2001 and analysed the results and follow-up of open surgery versus endovascular repair of AAA in patients with known Behçet's syndrome.

Results: Of the 53 patients with Behçet's disease 18 had vascular manifestations (34%). AAAs were encountered in 8 patients (15%) and 5 were treated. Open surgery (group 1), under general anesthesia, lasted less than 3 hours with an average aortic clamping time of 34 minutes (range 26–41 min) after which the patients were transferred to the intensive care unit for 24–48 hours. Endovascular treatment (group 2), although lasting about the same time without the need for intensive care, necessitated contrast media and fluoroscopy. The length of hospital stay was considerably shorter for patients after endovascular repair compared to open surgery (3 days vs. 6 days). Combined mortality and morbidity was higher in patients who underwent open surgery compared to endovascular repair (one death, one major amputation and three anastomotic pseudoaneurysms compared to one temporary contrast-induced nephropathy).

Conclusions: Vasculo-Behçet patients with AAA are better candidates for endovascular treatment than atherosclerotic patients. Combined morbidity (especially anastomotic pseudoaneurysms) and mortality of Behçet patients after endovascular repair is considerably lower than after open surgery.

Matrix metalloproteinases are a family of enzymes that degrade different components of extracellular matrix. They play an important role in normal physiologic processes of maintaining tissue integrity and remodeling, as in wound healing, processes of development, and regeneration. However, excessive expression of MMP[1] has been observed in many disease states, including rheumatoid arthritis and osteoarthritis, vascular remodeling in atherosclerosis and aortic aneurysm formation, neoplastic processes, macular degeneration and many others.
