STUDY DESIGN: Case report. OBJECTIVES: To report the development of high intensity zones in the lumbar posterior anulus on axial loaded magnetic resonance imaging. SUMMARY OF BACKGROUND DATA: The high intensity zone is seen in the posterior anulus of degenerate lumbar discs on T2-weighted magnetic resonance images and represents a radial anular tear. Although the specificity of the high intensity zone for a concordantly painful anular tear in patients undergoing discography for discogenic low back pain is high, the sensitivity of magnetic resonance imaging for identification of discographically demonstrated anular tears is approximately 30%. METHODS: A 55-year-old female with chronic low back pain was imaged with lumbar spine magnetic resonance imaging before and following axial loading with an magnetic resonance imaging-compatible compression device. RESULTS: The nonloaded study demonstrated degeneration of the lower four lumbar discs. Following axial loading, posterior central high intensity zones were identified at the L2-L3 and L4-L5 levels. CONCLUSION: High intensity zones developed on axial loaded magnetic resonance imaging of the lumbar spine. We postulate that lumbar spine magnetic resonance imaging with axial loading may increase the sensitivity of magnetic resonance imaging for the detection of high intensity zones.
In Jordan, the average life expectancy in 2002 was 72 years, and chronic diseases are becoming increasingly prevalent. Because personal behavior can influence the occurrence and progression of many chronic diseases, the Jordan Ministry of Health (JMoH) established surveillance for behavioral risk factors, particularly those related to cardiovascular diseases and diabetes. This report summarizes the key findings of the 2002 Behavioral Risk Factor Survey, the first reporting segment in Jordan's surveillance program for chronic diseases. The findings indicate that smoking, physical inactivity, and obesity contribute substantially to the burden of chronic disease in Jordan and underscores the need for effective public health interventions.
The apancreatic state secondary to resective surgery for chronic pancreatitis is associated with a high rate of late morbidity and mortality that is due, in part, to endocrine insufficiency. Resective procedures should, therefore, be used very selectively. Over the last 2 decades we have seen a shift from extensive distal resections to limited proximal resections. This is because of the lowering of the operative mortality of pancreatic head resection and its better results in pain relief, while preserving in situ the body and tail of the gland with its metabolic functions. Islet autotransplantation and segmental pancreatic autotransplantation were introduced in 1977 and 1978, respectively. Over 150 and 25 cases of these operations have been reported, respectively. Both techniques are evolving with a goal to improve results. Procedures placing the graft in the iliac fossa and anastomosing the pancreatic duct to the jejunum are now favored over groin placement and duct occlusion. Islet autotransplants achieve a higher yield of islet cells and decrease the exocrine impurity of the preparation. Both methods can prevent or delay the onset of diabetes mellitus, and when diabetes mellitus does occur, it is frequently easier to manage. The long-term function of the grafts appears to be dependent on the beta-cell mass available in the diseased pancreas, the loss of cells related to the transplant procedure, and the characteristics of gradual loss of function from the type of transplant used. Although extensive pancreatic resections are occasionally required, the possibility of autotransplantation should be considered in those patients.
