In order to determine a marker of prethrombotic states, reliable and easy to measure, we studied 200 patients under 60 years of age admitted to hospital for a precordial chest pain. Four groups were established: transmural myocardial infarction, acute infarction without Q wave, unstable angina and atypical chest pain. Fibrinogen, von Willebrand factor, cholesterol, and triglyceride levels were measured as well as the white cell and platelet counts. There was a statistically significant correlation between transmural myocardial infarction and increased levels of fibrinogen, von Willebrand factor and white blood cells. Von Willebrand factor was already increased in the acute phase of transmural infarction, reached a maximum on the fifth day and then decreased slowly during the following ten days. This study suggests that plasma von Willebrand factor could be a reliable marker of transmural myocardial infarction in the acute phase or during the two weeks following the thrombotic event.

Because they can obstruct blood vessels and release noxious substances, white blood cells may contribute to the development of tissue ischaemia. The flow properties of white cells were tested after myocardial infarction, by measuring the filtration rates of cell suspensions through 8 microns pore filters. Compared with mononuclear cells from age matched controls, mononuclear cells from patients with infarction showed impaired filterability within the first day after the onset of pain; this condition persisted for at least two days and by day 10 it was improved. On day 1, granulocyte filterability and the proportion showing morphological evidence of activation were nearly normal. By day 3 the flow resistance and activation had increased, but the changes seen depended on the age of the patient. The filterability and activation of granulocytes from patients aged less than 60 were significantly increased from day 1, whereas there were no changes in granulocytes from patients aged greater than 60 years. Suspensions of unfractionated white cells showed changes intermediate between the mononuclear cells and granulocytes. A group of five patients who presented with chest pain but who were subsequently found not to have had an infarction showed no evidence of abnormal filterability or activation. The changes in filterability probably reflect white cell activation, which may have an adverse effect on the perfusion of the ischaemic myocardium.

A 42-year-old man with an atypical pneumonia. He had chest pain and a dry cough for 3 weeks, was dull at the left base clinically, and had left lower zone consolidation on chest radiography. The pneumonia spread despite oral ampicillin and cloxacillin. Blood culture grew Listeria monocytogenes and white cell count showed a monocytosis. He responded to intravenous penicillin and gentamicin with complete X-ray clearance.

Platelet size has been shown to reflect platelet activity. We prospectively measured the mean platelet volume (MPV) in 47 patients undergoing single vessel angioplasty for symptomatic angina. The patients underwent repeat angiography 4-8 months later irrespective of symptomatic status. Restenosis was assessed quantitatively by hand held calliper measurements of the lesion and qualitatively by a return of angina, ST segment changes on an exercise test and visual analysis of the lesion severity by two experienced angiographers. Twenty-four patients developed recurrent angina during the follow-up period, the MPV in the group with chest pain was 8.54 +/- 0.60 fl compared to 8.1 +/- 0.69 fl in the asymptomatic group (P = 0.04). Twenty two patients had significant ST segment changes at exercise. In this group the MPV was 8.6 +/- 0.56 fl compared to 8.0 +/- 0.70 fl for the group with a negative test (P = 0.002). Similarly visually assessed angiographic stenosis showed a significant increase in the restenotic group (8.6 +/- 0.56 vs. 8.0 +/- 0.61 fl, P = 0.001). The relative odds for developing clinically defined restenosis were 10.2 times greater if the pre-procedural MPV lay in the upper compared to the lowest quartile. There was a positive correlation between MPV and change in minimal luminal diameter between post angioplasty and follow-up angiography, assessed quantitatively, r = +0.56, P = 0.016. There was no association between clinical or angiographic definitions of restenosis and haemoglobin, red cell count, mean corpuscular volume, white cell count or platelet count. Platelet size may influence the development of restenosis after successful coronary angioplasty.

We report on a patient of Ki-1 lymphoma-associated hypereosinophilic syndrome and eosinophilic polymyositis. A 22-year-old male was admitted to a hospital because of anterior chest pain, when he had a white cell count of 12,000 with 33% of eosinophils. He first noticed muscle weakness in the right shoulder at age 23 years. At the age of 25, he experienced marked muscle weakness in his arms and neck, which brought him to our hospital. Neurological examination on admission revealed moderate muscle atrophy and weakness in the neck flexors and both upper extremities, and marked muscle hypertrophy in the sternocleidomastoideus and trapezius muscles. Laboratory studies showed a white blood cell count of 17,700 with 56% of eosinophils. His serum creatine kinase (CK) level was elevated to 347 units. A muscle biopsy specimen showing active myositis infiltrated by eosinophils confirmed the diagnosis of eosinophilic myositis. Although eosinophilia and serum CK activity decreased markedly with corticosteroid treatment, his muscle weakness was unchanged. At the age of 27 years, lymphadenopathy developed. Immunocytochemical examination on a biopsied neck lymph node indicated Ki-1 lymphoma with positive Ki-1, CD45 and epithelial membrane antibodies. In spite of chemotherapy and local irradiation treatment, he died four months after the emergence of Ki-1 lymphoma. We discussed the relationship between hypereosinophilic syndrome, eosinophilic polymyositis and Ki-1 lymphoma on pathogenetic mechanism.

A 19-year-old male patient with type 1 Gaucher disease was put on regular biweekly infusions of alglucerase. After 1 yr of treatment, hepatic and splenic volumes decreased from 38 and 45 mL/kg to 31 and 34 mL/kg, respectively. In addition, hemoglobin concentration, platelet count and white cell count increased, acid phosphatase level decreased, and the patient gained weight and energy. Despite improvement, the patient refused enzyme replacement therapy (ERT) because of muscle rigidity, chest pain, trembling and anxiety, which he attributed to enzyme substitution. Two and 4.5 year after cessation of therapy, hepatic and splenic volumes increased to 36 and 53 mL/kg and to 53 and 110 mL/kg, respectively. The patient developed non-tractable hematuria because of compression and dislocation of the left kidney by the enlarged spleen, which necessitated splenectomy. This report suggests that cessation of ERT in Gaucher disease may result in severe and complicated rebound visceromegaly.
