1/1004. Aortic dissection in young patients with chronic hypertension.

    We describe four patients aged 14 to 21 years who developed acute aortic dissection. In three of the four patients, the course was fatal, despite aggressive medical and surgical intervention. All four patients had sustained systemic hypertension related to chronic renal insufficiency. The patients had no other identifiable risk factors for aortic dissection, including congenital cardiovascular disease, advanced atherosclerosis, vasculitis, trauma, pregnancy, or family history of aortic dissection. Although aortic dissection is rare in individuals younger than 40 years of age, young patients with sustained systemic hypertension are at increased risk for this serious and often fatal condition. physicians must be aware of this rare complication of hypertension and consider aortic dissection in the differential diagnosis of unusual chest, abdominal, and back pain in hypertensive children, adolescents, and young adults.

2/1004. The changes in human spinal sympathetic preganglionic neurons after spinal cord injury.

    We have applied conventional histochemical, immunocytochemical and morphometric techniques to study the changes within the human spinal sympathetic preganglionic neurons (SPNs) after spinal cord injury. SPNs are localized within the intermediolateral nucleus (IML) of the lateral horn at the thoraco-lumbar level of the spinal cord and are the major contributors to central cardiovascular control. SPNs in different thoracic segments in the normal spinal cord were similar in soma size. SPNs in the IML were also identified using immunoreactivity to choline acetyltransferase. Soma area of SPNs was 400.7 15 microm2 and 409.9 /-22 microm2 at the upper thoracic (T3) and middle thoracic (T7) segments, respectively. In the spinal cord obtained from a person who survived for 2 weeks following a spinal cord injury at T5, we found a significant decrease in soma area of the SPNs in the segments below the site of injury: soma area of SPNs at T8 was 272.9 /-11 microm2. At T1 the soma area was 418 /-19 microm2. In the spinal cord obtained from a person who survived 23 years after cord injury at T3, the soma area of SPNs above (T1) and below (T7) the site of injury was similar (416.2 /-19 and 425.0 /-20 microm2 respectively). The findings demonstrate that the SPNs in spinal segments caudal to the level of the lesion undergo a significant decrease of their size 2 weeks after spinal cord injury resulting in complete transection of the spinal cord. The impaired cardiovascular control after spinal cord injury may be accounted for, in part, by the described changes of the SPNs. The SPNs in spinal segments caudal to the injury were of normal size in the case studied 23 years after the injury, suggesting that the atrophy observed at 2 weeks is transient. More studies are necessary to establish the precise time course of these morphological changes in the spinal preganglionic neurons.

3/1004. Chronic radiodermatitis following cardiac catheterisation: a report of two cases and a brief review of the literature.

    Cardiac angiography produces one of the highest radiation exposures of any commonly used diagnostic x ray procedure. Recently, serious radiation induced skin injuries have been reported after repeated therapeutic interventional procedures using prolonged fluoroscopic imaging. Two male patients, aged 62 and 71 years, in whom chronic radiodermatitis developed one to two years after two consecutive cardiac catheterisation procedures are reported. Both patients had undergone lengthy procedures using prolonged fluoroscopic guidance in a limited number of projections. The resulting skin lesions were preceded, in one case, by an acute erythema and took the form of a delayed pigmented telangiectatic, indurated, or ulcerated plaque in the upper back or below the axilla whose site corresponded to the location of the x ray tube during cardiac catheterisation. Cutaneous side effects of radiation exposure result from direct damage to the irradiated tissue and have known thresholds. The diagnosis of radiation induced skin injury relies essentially on clinical and histopathological findings, location of skin lesions, and careful medical history. Interventional cardiologists should be aware of this complication, because chronic radiodermatitis may result in painful and resistant ulceration and eventually in squamous cell carcinoma.

4/1004. Use of transdermal amitriptyline gel in a patient with chronic pain and depression.

    A man with severe inflammatory bowel disease suffered from chronic abdominal pain and depression. A transdermal amitriptyline gel preparation was compounded since he was unable to take drugs orally serum concentrations of amitriptyline and its active metabolite nortriptyline were measured over 24 hours. Symptoms of depression were monitored before starting transdermal therapy and at the end of 6 weeks. Pain symptoms and amitriptyline adverse drug events were monitored daily Steady-state serum concentrations of drug and metabolite were within the therapeutic range over 24 hours. The patient reported that his mood was improved but his abdominal pain remained unchanged. Transdermal amitriptyline gel was well tolerated and is an alternative delivery system in patients unable to take drugs orally.

5/1004. fibromuscular dysplasia involving coronary arteries--a case report.

    The authors report a young patient with fibromuscular dysplasia involving multivessels including coronary arteries. If young patients have chest pain on effort, fibromuscular dysplasia of coronary arteries must be considered. As fibromuscular dysplasia is a chronic progressive disease and some cases progress rapidly in a few months, careful follow-up and comprehensive medical management may be necessary in such patients.

6/1004. Papillary endothelial hyperplasia presenting as a chest wall neoplasm.

    Soft tissue hematomas generally resolve but may persist and develop into slow-growing, organized masses. These chronic expanding hematomas are characterized by a pseudocapsule and a predominantly necrotic central cavity, with foci of newly formed capillaries. These have been called chronic expanding hematomas or Masson's papillary endothelial hyperplasia. These lesions can mimic vascular neoplasms and must be considered in the evaluation of expanding soft tissue vascular malformations.

7/1004. sciatic neuropathy secondary to a uterine fibroid: a case report.

    Lesions of the sciatic nerve outside the pelvis have been well described. Lesions within the pelvis, however, are far less common. We report the case of a 55-yr-old woman with a history of chronic low back pain who presented with progressive right buttock and posterolateral right lower limb pain associated with right foot numbness and tingling. She denied any associated low back or left lower limb pain. The patient was initially treated for a probable right lumbosacral radiculopathy, without improvement. A subsequent magnetic resonance image of the lumbosacral spine revealed multilevel disc degeneration at L3-4 through L5-S1, without disc herniation or canal stenosis. A magnetic resonance image of the pelvis revealed a markedly enlarged uterus, with a large pedunculated myoma impinging on the right sciatic foramen. The patient underwent a subtotal abdominal hysterectomy, with resolution of her right lower limb pain. This case illustrates the importance of considering intrapelvic causes of sciatic neuropathy. To our knowledge, this is the first reported case of sciatic neuropathy secondary to a uterine fibroid.

8/1004. Evolution of acute cytomegalovirus gastritis to chronic gastrointestinal dysmotility in a nonimmunocompromised adult.

    A 30-year-old nonimmunocompromised woman developed chronic gastrointestinal dysmotility as a consequence of acute cytomegalovirus infection. The acute nature of the infection was documented by high immunoglobulin m antibody titer to cytomegalovirus (CMV); the chronicity of the infection was shown by persistence of CMV in biopsy specimens of her gastrointestinal tract over a 21/2-year period. Gastrointestinal dysmotility was confirmed by delayed emptying on gastric nuclear scintigraphy, by retrograde propagation of migrating myoelectric complexes on small intestinal manometry, and by presence of tachygastria on cutaneous electrogastrography. The patient's nausea, vomiting, abdominal pain, and early satiety resolved after a short course of treatment with leuprolide acetate but returned after medication was discontinued. Her symptoms persisted despite clearance of CMV from the gastrointestinal tract after a course of treatment with ganciclovir. These observations show that acute CMV infection can cause gastrointestinal dysmotility in nonimmunocompromised individuals and that the disturbance in gastrointestinal motor function may persist for years after viral infection of the gastrointestinal tract has been eradicated.

9/1004. Treatment of a large congenital coronary fistula with coil embolization.

    A 77-year-old woman suffering from progressive dyspnea and chest pain for 2 1/2 years was admitted to hospital. There were no ECG changes at exercise test and a dobutamine stress echocardiography was normal. At catheterization, right-sided pressures were within normal limits. coronary angiography revealed a congenital coronary fistula, 3-4 mm in diameter, from the left anterior descending artery to the proximal pulmonary artery. There was no significant rise in blood oxygen saturation in the pulmonary artery. Transcatheter coil embolization was performed in the distal part of the tortuous fistula. Flow ceased within minutes, demonstrating the feasibility and efficacy of this technique for treating large fistulas.

10/1004. Disseminated nocardiosis in a bone marrow transplant recipient with chronic GVHD.

    We describe a case of disseminated nocardiosis in a 53-year-old male allogeneic marrow recipient with chronic GVHD, 15 years post BMT. Six months prior to admission he was treated for recurrent chronic GVHD with corticosteroids with a good response. He deteriorated subsequently while still on steroids requiring admission for fever, anorexia, weight loss, productive cough and progressive dyspnoea. On admission he had multiple nodular lesions on chest roentgenogram and subsequently grew nocardia farcinica in blood culture. N. farcinica is rare post BMT, has a high mortality, is resistant to various antibiotics and needs prolonged antimicrobial therapy. We report the successful management of our patient with single agent trimethoprim-sulphamethoxazole.
