Impaired hemorheology in patients with postmastectomy lymphedema.

Lymphedema of the arm is one of the most disabling and serious complications of breast cancer. Apart from tumor infiltration or fibrosis of lymphatic pathways, little is known about factors favoring the development of lymphedema. In the present study, we investigated the impact of rheologic parameters, e.g. red cell aggregation (EA) and plasma viscosity (PV), and of capillary morphology and capillary flow in patients with breast cancer with (n = 18) and without (n = 18) lymphedema. Patients with lymphedema showed a significant increase of red cell aggregation (p < 0.001) that indicates a systemic component of lymphedema and might offer a possibility of prevention and therapy of this condition. A hitherto unclassified protein factor favoring red cell aggregation and lymphedema might be postulated.

Serum levels of erythropoietin in acute Plasmodium falciparum malaria.

The pathophysiologic backgrounds of anemia in malaria are complex and multifactorial. The purpose of the present study was to measure serum concentrations of erythropoietin (EPO) and to evaluate the adequacy of EPO production in patients suffering from acute Plasmodium falciparum malaria. Fifteen patients with complicated malaria were included in the study. Serum samples were taken on the day of admission, and days 7, 14, 21 and 28. Serum EPO concentrations were measured using an enzyme-linked immunosorbent assay. The median serum EPO concentration was 15.6 mU/ml on the day of admission (range 0.5-567) mU/ml, 10.6 mU/ml (1.2-863) on day 7, 11.8 mU/ml (0.5-72.8) on day 14, 10 mU/ml (0.5-74.6) on day 21, and 8.3 mU/ml (2.2-61.6) on day 28. Inadequate EPO production was found in 46.6% of the patients on the day of admission, which increased to 67% and 68% on days 7 and 14, and reached a maximum of 80% on day 21. Almost 54% of patients had inadequate EPO production on day 28. Our data indicate inadequate EPO production in patients suffering from acute P. falciparum malaria, which might contribute to the prolonged anemia observed in these patients.

Experience with outpatient intravenous teicoplanin therapy for chronic osteomyelitis.

Thirty-seven patients with acute exacerbations of chronic osteomyelitis caused by methicillin-susceptible Staphylococcus aureus (n = 13), methicillin-resistant Staphylococcus aureus (n = 12), methicillin-susceptible coagulase-negative staphylococci (n = 9), methicillin-resistant coagulase-negative staphylococci (n = 1) and enterococci (n = 2) were treated intravenously with teicoplanin. After a loading dose of 7 to 16 mg/kg (median 11 mg/kg) for 4 to 7 days, patients received 9 to 25 mg/kg (median 14 mg/kg) on Mondays, Wednesdays and Fridays in an outpatient setting to reach trough serum levels between 5 mg/l and 15 mg/l. The duration of treatment ranged from 28 to 150 days (median 60 days). Cure was obtained in 14 (38%) and improvement in 17 (46%) cases, and failure was observed in 6 (16%) patients. Adverse effects occurred in 6 patients, and caused discontinuation of treatment in 3 patients. The financial savings exceeded US$60,000 per patient compared with the high hospitalization costs of inpatient treatment.

Effect of cefodizime and ceftriaxone on phagocytic function in patients with severe infections.

Thirty patients with severe bacterial infections were treated with 50 mg of cefodizime per kg of body weight once daily or 50 mg of ceftriaxone per kg once daily for 10 +/- 3 days. The effect of cefodizime and ceftriaxone on the phagocytic capacity and generation of reactive oxygen intermediates after phagocytosis by granulocytes was assessed prior to, during, and after therapy. Flow cytometry was used to study phagocytic capacity by measuring the uptake of fluorescein-labeled bacteria. The generation of reactive oxygen intermediates after phagocytosis was estimated by the quantification of the intracellular conversion of dihydrorhodamine 123 to rhodamine 123. Prior to therapy, patients in both groups exhibited a decreased capacity to phagocytize Escherichia coli and subsequently to generate reactive oxygen intermediates. Granulocyte function increased after the initiation of therapy and normalized within 7 days for the ceftriaxone-treated patients and within 3 days for the cefodizime group (P < 0.05). In the cefodizime group, an enhancement of phagocytic capacity was observed 14 days after the initiation of therapy (P < 0.05). Prior to therapy, phagocytic capacity was significantly correlated with the generation of reactive oxygen products (r = 0.674 and P < 0.005).

Extrapulmonary tuberculosis with paravertebral abscess formation and thyroid involvement.

Extrapulmonary tuberculosis has a broad spectrum of clinical manifestations. Involvement of the thyroid gland has rarely been reported. We report a case in a patient with a non-tender swelling of the thyroid, whose symptoms, sonographic and scintigraphic features mimicked carcinoma. Initially the patient presented with back pain due to a paravertebral mass. Fine needle aspiration and culture of the aspirate both from the paravertebral mass and the thyroid ensured the diagnosis. Although seldom observed, tuberculosis should be kept in mind in the differential diagnosis of nodular lesions of the thyroid. The preponderant absence of thyroid dysfunction in mycobacterial thyroiditis is confirmed by this case.
