1/20. Diabetic microangiopathy in the small bowel.

    AIMS: Microangiopathic changes in the gastrointestinal tract of patients with diabetes mellitus are frequently mentioned in the clinical literature. To our knowledge, pathological studies documenting these changes in bowel biopsies have not been previously reported. In this report, we describe striking duodenal biopsy findings of diabetic microangiopathy in a patient with long-standing insulin-dependent diabetes mellitus and chronic diarrhoea. methods AND RESULTS: The diagnosis was based on the histopathological and immunohistochemical findings in the appropriate clinical setting. blood vessels within the duodenum displayed prominent mural thickening and luminal narrowing secondary to accumulation of hyaline material, which was periodic acid-Schiff positive and intensely stained with monoclonal antibodies against type IV collagen. CONCLUSIONS: This is the first report of diabetic microangiopathy in a bowel biopsy. The pathogenesis, specificity and significance of these angiopathic changes, controversies about diabetic microangiopathy in the gastrointestinal tract, and the association with hypertension are discussed.

2/20. Spontaneous splenic infarction secondary to diabetes-induced microvascular disease.

    splenic infarction is a clinical entity seldom encountered. The most frequent causes of splenic infarction include thromboembolic phenomena, hematologic malignant neoplasms, and vasculitides. We describe a patient who sustained splenic infarction secondary to diabetes-induced, small-vessel atherosclerotic disease.

3/20. Combined long-segment angioplasty and stenting of the superficial femoral artery and popliteal-distal bypass for limb salvage.

    The treatment of multisegment superficial femoral artery and tibial vessels atherosclerotic disease is traditionally a femoro-distal bypass using in situ or reversed autogenous vein. The improved result of balloon angioplasty and stenting of the superficial femoral artery (SFA) has extended its application to treat long segment SFA stenosis. A combined endovascular-open surgery approach of SFA endovascular stenting with a popliteal-distal bypass is an alternative less invasive procedure to achieve optimum distal revascularization for limb salvage.

4/20. Asymptomatic coronary artery disease in a pregnant patient. A case report and review of literature.

    BACKGROUND: Acute myocardial infarction during pregnancy has been reported and has been shown to be associated with poor maternal and fetal outcomes. However, the vast majority of these patients do not have previously recognized ischemic heart disease. pregnancy and delivery pose significant cardiac stress and risk to the mother and fetus. However, it is unknown how available therapies can be utilized in the pregnant patient with identified ischemic heart disease to minimize these risks. CASE REPORT: We present a 39-year-old asymptomatic diabetic female with a positive stress echocardiogram at 16 weeks of pregnancy who remained asymptomatic throughout pregnancy with medical management and went on to have a normal vaginal delivery in the process suffering a small non-ST elevation myocardial infarction with pulmonary edema following delivery due to volume overload. She ultimately underwent cardiac catheterization and successful four-vessel CABG 1 months after her delivery. CONCLUSION: We present this patient to suggest a successful strategy of managing a patient with non-revascularized asymptomatic coronary artery disease during pregnancy. In addition to reviewing the appropriate medical therapy during pregnancy, we discuss the data on revascularization procedures as well as recommendations for delivery and stress testing for such patients.

5/20. Assessment of peripheral vascular disease in patients with diabetes. Two case studies.

    This report proposes that perfusion scanning in combination with arteriography be included in the diagnostic work-up of the diabetic patient who, because of peripheral vascular complications, is a candidate for surgery. Two cases are reported which illustrate the extremes of the findings: abnormal arteriogram-normal scan indicating large-vessel disease without significant small-vessel involvement. It is suggested that these patients are candidates for vascular reconstruction. The other extreme is the normal arteriogram-abnormal scan indicating small-vessels disease without significant large-vessel involvement. It is apparent that these patients are not candidates for vascular reconstruction.

6/20. Successful percutaneous coronary intervention for acute myocardial infarction caused by simultaneous occlusion of two major coronary arteries in patients with diabetes mellitus. A report of two cases.

    percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) is a common therapeutic method. Although two or more culprit lesions are rarely observed simultaneously in AMI patients, we present two cases of AMI caused by simultaneous occlusion of two major coronary arteries, the left anterior descending and right coronary arteries. In both cases, emergency PCI for the two major vessels was successful. Both patients had type 2 diabetes mellitus, which might have contributed to simultaneous occlusion of the two coronary arteries.

7/20. Normocytic normochromic anemia due to automatic neuropathy in type 2 diabetic patients without severe nephropathy: a possible role of microangiopathy.

    We describe here four male patients with long-term and poorly controlled type 2 diabetes mellitus. They shared many common characteristic complications, such as severe autonomic neuropathy, proliferative retinopathy and normocytic normochromic anemia without progressive renal failure and macroangiopathy. They also showed normal levels of erythropoietin and reticulocyte, which was considered relatively low. The coefficient of variation of R-R, a useful method to estimate autonomic failure, showed markedly advanced autonomic neuropathy in all four patients. coronary angiography did not reveal stenosis, anomaly or collateral vessels, but left ventriclography showed diffuse or partial hypokinesis. Massive proteinuria, high urinary levels of N-acetyl-beta-D-glucosamidase (NAG) and beta2-microglobulin (beta2M) were detected, though creatinine clearance (Ccr) was not so deteriorated. Treatment with recombinant erythropoietin increased their hemoglobin and hematocrit levels. These common points have a possibility to be brought about by tubulointerstitial damage and microangiopathy may be involved in it.

8/20. Ischaemic necrosis of the glans penis: a complication of urethral catheterization in a diabetic man.

    Ischaemic necrosis of the glans penis is rare. Diabetic patients commonly have small vessel disease which may affect the penis. We report the case of a man with extensive diabetic vascular disease, in whom partial penectomy was necessary for ischaemia of the glans penis, following urethral catheterization. The decision to use a urethral catheter in diabetics, particularly those with evidence of vascular disease, must be made with the knowledge that internal compression caused by the catheter may cause irreversible ischaemic changes. In such patients, a suprapubic catheter should be considered as an alternative.

9/20. Two case reports of macrovascular complications in fibrocalculous pancreatic diabetes.

    Fibrocalculous pancreatic diabetes (FCPD) is a form of diabetes secondary to chronic, non-alcoholic pancreatitis in tropical countries. Being a secondary form of diabetes, vascular complications are believed to be rare. In this paper we present two case reports of macrovascular complications (myocardial infarction and gangrene). This shows that large vessel disease does occur in FCPD.

10/20. Granulomatous angiitis of the central nervous system: protean manifestations and response to treatment.

    Granulomatous angiitis is an uncommon necrotising vasculitis of unknown cause restricted to vessels of the central nervous system. Five tissue-proven cases emphasise the protean manifestations of this disease and the difficulties encountered in reaching a diagnosis. One patient presented with a temporoparietal mass, the second, a progressive dementia, the third suggested herpes simplex encephalitis, the fourth mimicked multi-infarct state; and the fifth presented with a cerebellar mass lesion. In four cases with CSF examination, protein was elevated (81-193 gm/l) and three patients had mononuclear pleocytosis (12-800 WBC/mm3). Cerebral arteriogram suggested vasculitis in only one of four cases. diagnosis was made by brain biopsy in three cases and all three were treated successfully. The diagnosis in the two other cases was made at postmortem examination.
