The German health care system: a model for hospital reform in the United States?

Experience in Germany illustrates that the United States could potentially achieve universal access, comprehensive and high-quality services, and value for the money expended with what is often referred to as a "quasi-private and quasi-public" health care system. The German hospital system is analyzed from a number of perspectives, and it is concluded that this approach has some advantages over a single-payer, monolithic-type national health insurance model. This is primarily because of its pluralistic prepayment system and because the commencement of reimbursement negotiations are without direct governmental intervention. The adoption of the German design in the United States, it is concluded, would result in a sharp change in policy direction from a conceptually procompetitive, market-driven hospital environment to a highly federally regulated, state-administered one. The implementation of the German approach in this country would also require a shift from managed care plans and other third party payers having to micromanage the use of health care services for individual patients to tightly centralized national and state fiscal controls (e.g., institutional global capital and operating budgets) targeted at providers.     

Phase I study of Datelliptium chloride,hydrochloride given by 24-h continuous intravenous infusion

Summary Datelliptium chloride, hydrochloride (SR 95 156B, NSC 626718X, DHE) was studied in a phase I trial of escalating doses given on a single 24-h continuous intravenous infusion schedule. Doses were escalated from 40 to 500 mg/m² in 19 patients who received a total of 24 courses. Courses were repeated after a minimal interval of 3 weeks. Local venous toxicity occurred at low doses (100 mg/m²) and was circumvented by the use of a central venous access for higher doses. Other clinical adverse events occurred (330 mg/m²), including moderate nausea and vomiting, mild diarrhea, dry mouth, neuropsychiatric manifestations, and fatigue. All of these side effects were reversible and none was dose-limiting. The dose-limiting toxicity was related to hepatic laboratory-test abnormalities in the form of reversible elevations of levels of serum bilirubin and liver enzymes at doses of 330 mg/m². The maximum tolerated dose for this schedule is 500 mg/m². Hematologic toxicity was minimal and non-dose-limiting. Neither drug-related deaths nor objective complete or partial responses were observed. However, a minor response and a long-term disease stabilization were obtained.     

Parathyroid anatomy in hyperplasia.

Pathologically enlarged parathyroid glands offer the surgeon a vital medium for studying parathyroid anatomy. The advantages include gland magnification, rapid-section diagnosis to aid dissections, and postoperative clinical and laboratory responses to check for "missed" or supernumerary glands. In this series, each of 71 patients had at least four hyperplastic glands. Both mediastinal and intrathyroidal glands occurred in nine instances (13%), supernumerary glands in eight (11%), and ectopic neck glands in seven (10%). In total, anomalous parathyroid glands occurred in almost half (46%) of these patients with parathyroid hyperplasia.     

Results of 25 years of kidney transplantation

Between 1975 and 2000, 1008 renal transplantations were performed in 935 recipients at Henri Mondor hospital. The mean objective of this study is to analyse patient and graft survivals at long term. For kidney transplantations performed respectively before and after 1985, ten years patient survival was 74.3% +/- 0.03 and 85.7% +/- 0.01, p = 0.03 and ten years graft survival was 39.5% +/- 0.04 and 71.9% +/- 0.02 after 1985, p = 0.001. Since 1985, an enhancement in graft actuarial survival still improved (one year survival 86.1% +/- 0.01 versus 90.8% +/- 0.02, three years survival 78.5% +/- 0.02 versus 85.5% +/- 0.02, five years survival 71.7% +/- 0.02 versus 78.8% +/- 0.04, for the years 1985-1994 versus 1995-2000, p < or = 0.05). Immunosuppressive drugs may contribute to results enhancement in kidney transplantation while other non immunologic factors are becoming more predominant.     

Caecal Volvulus in the Marden-Walker Syndrome : an Uncommon Association of Two Rare Diseases in a 4-Year Old Child. Case report

The authors report a case of caecal volvulus associated with Marden-Walker syndrome in a 4-year old girl. They point out the diagnostic difficulties of this devastating disease specially in debilitated children.     

Unmeasured anion during severe sepsis with metabolic acidosis

It is assumed that the development of metabolic acidosis during sepsis is secondary to lactic acidosis. We assessed the composition of the anion gap during severe sepsis induced by cecal perforation in rats. In the first experiment, cardiac output, arterial blood gases, and arterial lactate were measured over a 6 hr interval in five septic rats and in five rats serving as sham-operated controls. The cardiac output decreased from 331 +/- 32 to 172 +/- 9 ml/kg/min (P less than 0.01) in the septic rats. Although the arterial lactate was increased to 2.1 +/- 0.2 mEq/L in septic rats compared to 0.8 +/- 0.1 mEq/L in sham rats (P less than 0.01), the HCO3- was decreased to 16.5 +/- 0.6 mEq/L in septic rats versus 23.8 +/- 1.10 mEq/L in sham rats (P less than 0.01). We further investigated this bicarbonate deficit in a second study in which arterial blood was sampled at 6 hr for blood gases, and plasma Na+, K+, Cl-, HCO3-, lactate, pyruvate, beta-hydroxybutyrate, acetoacetate, citrate, creatinine, albumin, and amino acids in five septic and five sham rats. The serum anion gap was calculated as [(Na(+) + K+) - (Cl(-) + HCO3-)]. The anion gap was 21.6 +/- 1.6 mEq/L in the septic animals as compared to 13.2 +/- 0.5 mEq/L in the sham animals (P less than 0.01). There were no differences in the concentration of pyruvate, beta-hydroxybutyrate, acetoacetate, citrate, creatinine, albumin, or amino acids.(ABSTRACT TRUNCATED AT 250 WORDS)     

Eosinophil autofluorescence and its use in isolation and analysis of human eosinophils using flow microfluorometry

Unstained human eosinophils exhibit unusually bright autofluorescence, which allows them to be distinguished from other leukocytes using fluorescence microscopy. Eosinophil fluorescence is associated with the cytoplasmic granules of the cells. Eosinophil granule extracts, containing an as-yet-undefined eosinophil fluorescence factor, exhibited excitation maxima at 370 nm and 450 nm, with maximum emission at 520 nm. Eosinophils adhering to opsonized parasites in vitro deposit fluorescent material onto the parasite surface. Eosinophil fluorescence was of sufficient intensity to allow the preparation of viable, highly enriched (greater than or equal to 98%), eosinophil suspensions from peripheral blood of normal and eosinophilic donors using a fluorescence- activated cell sorter. Quantitative studies of eosinophil autofluorescence were performed using flow microfluorometry. Fluorescence intensity of blood eosinophils from normal volunteers and eosinophilic patients varied inversely with the log of the donor's absolute eosinophil count regardless of clinical diagnosis.
