This article reviews the radiologic and endoscopic diagnosis of Crohn's disease. Radiographic and endoscopic findings of Crohn's disease are discussed; a practical approach to the selection of radiologic modalities is presented; and the role of endoscopy in diagnosis and treatment is explained.
Crohn's disease of the small bowel frequently requires surgical intervention. While dealing with the disease complications that require intervention, treatment should be based on a long-term strategic plan that recognizes the likelihood of recurrent disease, repeat surgeries, and the possibility of a future ostomy. Resection forms the basis for surgical treatments, but strictureplasty, abscess drainage, intestinal and diversion bypasses also are used, selectively.

Acute and chronic visceral ischemia are now well recognized clinical entities and extensive progress has been made in both the evaluation and treatment of patients with these lesions. The visceral vessels and the nature of their collateral pathways can also be of critical importance when dealing with other intra-abdominal pathology. Poor anastomotic healing, or the formation of strictures and intestinal fistulas may result when the mesenteric circulation is slowly compromised. Hence, it is imperative that the visceral arteries, their lesions, and their collateral pathways be understood by all surgeons operating in the abdominal cavity.
This article has dealt briefly with intravenous nutrition in intestinal disorders. The indications for its use and techniques of nutritional assessment have been stressed. The use of intravenous hyperalimentation in a few of the more common diseases of the small bowel and colon has been discussed. Every patient with disease of the small or large intestine has some degree of dysfunction in the gastrointestinal tract. In many instances, this functional impairment interferes with normal ingestion or absorption of nutrients and predisposes the patient to malnutrition. The presence of malnutrition increases the morbidity and mortality of surgery and can be reversed by using intravenous hyperalimentation. Those patients with extreme short bowel syndrome secondary to intestinal disease or its parenteral nutrition at home. We stress the importance of a team approach to hyperalimentation. The evolution of a team of nutritional experts will improve the care of the patient and the education of the patient and physician and make nutritional support more readily available to those medical and surgical patients in need.

INTRODUCTION AND OBJECTIVES: A quarter of patients waiting for kidney transplantation are patients with previous graft failure. Outcome of first and second renal transplant make these the gold standard for end renal stage disease, but this is not so clear in the case of third and further renal transplant, especially at the time of organ shortage. We revise our experience in patients with three or more kidney transplants focusing on surgical aspects and graft outcome. MATERIAL AND METHOD: 1364 renal transplants have been carried out in our centre since 1975 until December 2003. We have retrospectively revised the 34 patients with three renal transplants and the 5 with four. We analyse the surgical technique, surgical complications and graft outcome. RESULTS: Mean age was 42 years (21-65). Average mismatches between donor and recipient was 3.2. All kidneys, but one case of living donor, were harvested from cadaver donors, mostly in multiple organ-procurement. Average time from the last renal transplant was 5 years (3 days-17 years) and from the last transplant carried out in the iliac fossa reused until the new transplant was 9 years (3 days- 17.5 years). All implants were performed through an iterative lumboliliac incision (25 on the right side, 11 on the left one and in 3 cases where side was not registered). Mean average duration of the procedure was 166 minutes (100-300). Nephrectomy of previous graft at the moment of the implant was carried out in 13 patients (33%). Vascular anastomosis was made on the common iliac vessels (50%) or on the external ones (50%) in end to side way, Ureteroneocystostomy was performed in an extravesical way except in 1 patient with cutaneous diversion. Vascular complications were 4 haemorrages (1 patient died), 3 venous and 2 arterial thrombosis. We had an abscess secondary to intestinal fistulae. Other surgical complications were 4 lymphoceles, three of them needed surgical treatment, and one perirenal haematoma treated in a conservative way. No urological complications were seen. In total 6 grafts (15%) were lost due to surgical complications. Graft actuarial survival rate at 1 year was 65%, 40% at 5 and 28% at 10 years. CONCLUSIONS: Three and four renal transplant survival rates are shorter than first and second ones. Iterative access through lumboiliac incision is associated with a higher vascular complication rate, probably in these patients a transperitoneal access would be better. Multicentric studies with higher numbers of patients are needed to define more clearly which patients would benefit from multiple kidney retransplants.
OBJECTIVE: A gynaecological-obstetrical causation review in Dubrovnik from 1555 to 1557. Extract from the book "Curationum Medicinalium Centuriae V et VI" Amatus Lusitanus. METHOD: A thorough life and work archive study of Amatus Lusitanus has been made and, for this review, extracted his gynaecological-obstetrical causation observations and annotations. RESULTS: Amatus Lusitanus was an undisputed, reputable and respected medical figure during the mid 16th century. He decisively focused on intern medicine, incorporating the gynaecological-obstetrical field. His work and skill, most assuredly, contributed to the better comprehension, acknowledgement and reputation of the gynaecological-obstetrical practice, thus leaving repute and respect in medical history latitude. CONCLUSION: All these cases occurred in Dubrovnik during 1555-1557 and Amatus is assuredly an excellent observer and exactist, extracting the "relevant from the non-relevant" even in Dubrovnik's gynaecological-obstetrical daily happenings. He thoughtfully concludes his inability to remedy a malignant, advanced illness of the uterus, presumes an utero-vesico-intestinal fistula and openly speaks of medical ineptness of this causation. Proud of his invention in treating "contracted nipples"; correct in his advice and recommendations of "long and difficult births". Impartial in his perception of puerperal sepsis and its unfavourable pathology outcome. His description of "hormone insufficiency" is concise and precise; the preferred procedure in an "abortus in tractu" is purposeful and meaningful. He closely works with other physicians living and working in Dubrovnik; conscientiously directing surgeons in procedures of stillborn child births. He explains and treats pyschosexual disturbances "without fault" and in concurrence with, not only, the contemporary knowledge of such sexual disturbances, but also in concurrence with contemporary psychiatric procedures that, even today, are applied in such pathology treatment.
Polymicrobial anaerobic meningitis is a rare event secondary to a contiguous infection in the head or neck. Anaerobic meningitis due to a meningo-intestinal fistula is a rare event with only two cases reported in the literature. We describe a new case of adult polymicrobial anaerobic meningitis after colorectal surgery and radiotherapy and review the previous two cases.
The clinical significance of lipoprotein-X (Lp-X) induced by intravenous infusion of 10% fat emulsion was assessed, with special reference to atherogenesis, by in vitro experiment using purified Lp-X from the sera of patients receiving Intralipid 10%. Lp-X appeared after long-term intravenous infusion of 10% fat emulsion in the patients with intestinal fistula due to the anastomotic leakage. To clarify the role of Lp-X in terms of atherogenicity, the cholesterol metabolism of Lp-X in macrophages as scavenger cells and in hepatocytes as parenchymal cells was studied. When [3H]cholesterol-labeled Lp-X or oxidized low-density lipoprotein (o-LDL) was incubated with J-774 macrophages, the incorporation of Lp-X into macrophages was negligible compared with o-LDL. When Lp-X or high-density lipoprotein (HDL) was incubated with J-774 macrophages laden with [3H]cholesterol, the release of cholesterol from macrophages was enhanced by Lp-X as well as HDL. When [3H]cholesterol-labeled Lp-X LDL or HDL was incubated with the human hepatoma cell line of Hep G2 cells, the incorporation of Lp-X into Hep G2 cells was less than that of LDL, but similar to that of HDL. From these findings, it is suggested that the catabolism of Lp-X cholesterol generated with intravenous 10% fat emulsion was mediated by hepatocytes rather than by macrophages, indicating that the hyperlipidemia due to increased Lp-X may not be atherogenic.
