1/417. Sickle cell-like crisis and bone marrow necrosis associated with parvovirus B19 infection and heterozygosity for haemoglobins S and E.

    In the literature, heterozygosity for haemoglobins S and E is known as a clinically benign condition. Nevertheless, we present a case of double heterozygosity manifesting as an infarctive sickle cell-like crisis with acute chest syndrome and reversible bone marrow necrosis. Importantly, these complications were associated with serologically documented parvovirus B19 infection. Reviewing the literature, this case emphasizes a specific role of parvovirus B19 as a precipitating cause. Furthermore, it demonstrates how important the consideration of haemoglobin disorders can be even outside of the historically known areas.

2/417. Necrotizing sarcoid granulomatosis in a 14-yr-old female.

    A case of a 14-yr-old female with necrotizing sarcoid granulomatosis (NSG) is presented. She was referred because of chest pain and malaise, and radiography revealed multiple pulmonary nodules. Her history showed seasonal sensitization to aeroallergens and hay fever. Infectious agents or malignancies did not characterize these nodules. However, she was treated with macrolide antibiotics because of suspected infection with chlamydia pneumoniae. Open lung biopsy showed histological findings of NSG, with epithelioid granulomatous inflammation, including giant cells, and vasculitis. No further treatment was performed, and symptoms disappeared within a few weeks. The chest radiograph showed gradual improvement. The aetiology of NSG is poorly understood, and is postulated to represent either sarcoidosis or rare forms of pulmonary vasculitis such as Wegener's granulomatosis or the churg-strauss syndrome. In the case presented, a coincidence of infection with chlamydia pneumoniae suggests an involvement of infectious agents in the pattern of formation of immune complexes in the aetiology of NSG.

3/417. Polyester fibre prosthetic anterior cruciate ligament implant rupture: necrosis of ingrown connective tissue.

    AIMS: To describe the histopathological and microanalytical features in seven cases of ruptured Apex(R) polyester (Terylene(R)) fibre anterior cruciate ligament prosthesis. methods AND RESULTS: Transmitted and polarized light microscopy was performed in all cases; one case was investigated by immunohistochemistry, transmission electron microscopy and scanning electron microscopy, with backscatter and X-ray detectors for elemental microanalysis. For comparison we also studied synovial biopsy material and unused polyester fibres. In the excised ligaments there was much ingrowth of fibrous tissue accompanying a florid giant cell reaction to the individual intact polyester fibres throughout the ligaments. phagocytosis of particles of prosthesis-derived material was demonstrated and a striking finding was of necrosis of the ingrown connective tissue in the central portions of the ligaments. Hyalinized areas and 'neoligament growth' were less striking. A consistent finding in the polyester fibres was of small particles containing antimony, used as a catalyst in the manufacturing process. CONCLUSIONS: The pattern of reaction to the prosthetic material and the presence of necrosis differ from previous descriptions in animal and human explants of this and other prosthesis types. The mechanical effect of the necrosis is unlikely to be of significance with this ligament, which is load-bearing ab initio.

4/417. Laminar cortical necrosis in central nervous system lupus: sequential changes in MR images.

    A 44-year-old woman with systemic lupus erythematosus developed central nervous system lupus presenting with headache, fever, cloudiness of consciousness, and psychotic symptoms. T1-weighted and proton MR images showed laminar high intensity lesions in the parietal and temporal cortex bilaterally. T2-weighted images of the lesions showed low signal intensity. Treatment with corticosteroids alleviated the clinical symptoms within 7 months. The low T2 and high T1 signal abnormalities disappeared in a year and in 5 years, respectively. The laminar cortical lesions on MR images were suggested to represent cortical necrosis associated with central nervous system lupus.

5/417. Massive myocardial necrosis in thrombotic thrombocytopenic purpura: a case report and review of the literature.

    Thrombotic thrombocytopenic purpura (TTP) is an uncommon syndrome resulting from diffuse occlusion of small arterioles and capillaries by hyaline microthrombi. It is characterized by fever, thrombocytopenic purpura, microangiopathic hemolytic anemia, and neurologic and renal dysfunction. While cardiac pathology in TTP is commonly seen at autopsy, clinical cardiac dysfunction is rare and typically results from conduction system involvement. While 3% to 8% of patients with TTP report chest pain on admission, reports of fatal ventricular pump failure are extremely rare. We now report a case of TTP resulting in death from widespread myocardial necrosis. This patient presented with elevated cardiac enzymes and electrocardiographic disturbances that mimicked viral myocarditis, as well as a profound thrombocytopenia. Such a case may represent the extreme of a distribution of cardiac involvement in TTP or the consequence of an unidentified autoimmune process capable of precipitating severe myocardial TTP.

6/417. Descending necrotizing mediastinitis: report of a case.

    A 47-year-old man was admitted to our hospital for treatment of an odontogenic infection. He presented with a fever, signs of sepsis, and neck swelling, and was initially diagnosed as having a neck abscess. After cervical drainage, he showed no improvement, and mediastinitis was detected by chest X-ray and computed tomography. A thoracotomy and mediastinal drainage was subsequently performed for descending necrotizing mediastinitis, which resulted in marked improvement. To date, only 83 cases of descending necrotizing mediastinitis have been reported in japan. We present herein an additional case, followed by a review of the Japanese literature.

7/417. Hepatocellular carcinoma with spontaneous regression of multiple lung metastases.

    Spontaneously regressed lung metastasis of hepatocellular carcinoma (HCC) in a 82-year-old Japanese man with liver cirrhosis was recorded. Multiple nodular lesions of both lungs, up to 1 cm across, were shown on chest X-ray when the clinical diagnosis of HCC was made because of the presence of a liver mass on abdominal computed tomography (CT) scan and high serum alpha-fetoprotein (AFP) value. The lung lesions which were regarded clinically as metastasis of HCC decreased in number and size 7 months later, and subsequently disappeared a further 7 months radiographically. However, the liver mass revealed no reduction on abdominal CT, despite normalization of the serum AFP value, and the patient died 7 months after the disappearance of the lung lesions. The patient refused biopsy for the liver mass and anticancerous treatment during the course of the disease. At autopsy, the liver mass, 13 cm in diameter, histologically featured moderately differentiated HCC. Only one metastasis, 0.5 cm across, was obvious in the left lower lung lobe. In addition, there were 14 minute lesions in both lungs, up to 0.2 cm across, including three with complete necrosis and 11 with histocytic reaction and fibrosis. The necrotic tissue was filled with large ghostly cells that appeared to be debris from a neoplastic tissue, regardless of no viable tumor cells among them. The clinical and autopsy findings highly suggested that the patient developed spontaneous regression of multiple lung metastases of HCC and subsequently left the very small lesions as the vestige. Thus, the histology of these lesions may exhibit a process of the regression as the sequence of events, i.e., a transition from necrosis of the metastatic HCC to its fibrosis. Presence of an effective factor(s) in relation to the regression was unclarified. There has been no reported cases with regression of the only metastasis of HCC in the literature to date.

8/417. Necrotizing infection of the face secondary to intranasal impaction of "crack" cocaine.

    "Crack" is a crystalline form of cocaine that is readily available and sold in the form of small granules. The authors report a unique case of forced intranasal impaction of crack cocaine with subsequent extensive necrosis of the nose and upper lip accompanied by a necrotizing infection of the subcutaneous soft tissue of the cheeks, forehead, and temporal regions. The treatment of extensive facial necrosis resulting from infection and ischemia centers around the early diagnosis of the infectious process, prompt and aggressive surgical debridement, and the administration of broad-spectrum antibiotics.

9/417. Massive noninflammatory periportal liver necrosis following concentrated acetic acid ingestion.

    In a fatal occurrence of massive liver necrosis following ingestion of concentrated (90%) acetic acid, the patient showed evidence of hemolysis, disseminated intravascular coagulation, and liver dysfunction at only 45 minutes after exposure. With refractory to vigorous supportive care, the patient s condition deteriorated until death occurred 39 hours after ingestion, despite some improvement of coagulopathy. autopsy revealed corrosive injuries in the upper gastrointestinal tract and massive hepatic necrosis in a periportal distribution without significant inflammation. A direct effect of the noxious agent on hepatocytes involving the portal circulation is suggested.

10/417. Duodenojejunitis: is it idiopathic or is it Henoch-Schonlein purpura without the purpura?

    BACKGROUND: Henoch-Schonlein purpura is a small-vessel vasculitic disease that most often affects the skin. Gastrointestinal manifestations have been well described, including duodenojejunal inflammation (DJI). methods: Four children with DJI and clinical features of HSP are described, in whom the rash was either not present or appeared atypically late in the illness. RESULTS: The characteristic rash did not develop in three children, and it developed much later in one. The patients (three boys and one girl) were aged between 7 and 9 years (mean, 7.5 years). growth characteristics were normal. In all patients, pain occurred acutely with colicky abdominal pain in the spring or fall of the year, and all stools were positive for occult blood. No infectious cause was identified. Upper gastrointestinal endoscopic examinations demonstrated significant visual and histologic duodenitis in a pattern consistent with previous reports in children with known HSP. factor xiii activity was absent. immunoglobulin a levels were increased in three of four children. All children made a prompt recovery with the administration of intravenous glucocorticoids. In one child, the characteristic rash of HSP developed 18 weeks after the initial examination. CONCLUSION: Duodenojejunal inflammation may be the primary manifestation of HSP, even in the absence of the characteristic rash.
