Factors associated with hospitalization charges for cleft palate repairs and revisions.
ABSTRACT The objective of this study is to provide nationally representative estimates of cleft palate correction and revision procedures performed in hospitalized patients, as well as to examine patient- and hospital-level factors associated with hospitalization charges.
The Nationwide Inpatient Sample for the year 2007 was used. All hospitalizations that had a cleft palate correction or revision of cleft palate repair were selected. Estimates of concomitant procedures performed during the index hospitalization were obtained. The roles of different patient- and hospital-level variables on hospitalization charges were examined by use of multivariable linear regression analysis.
A total of 5,969 repairs and/or revisions of cleft palate procedures were performed in hospitals in the entire United States. The mean age per hospitalization was 3.2 years. Whites accounted for 51.3% of procedures, whereas blacks, Hispanics, Asian/Pacific Islanders, Native Americans, and other races accounted for 4.9%, 26.4%, 9.2%, 3.2%, and 5%, respectively. The mean charge per each hospitalization was $19,227, and the total hospitalization charge for the entire United States was $112.96 million. Patients aged less than 1 year (P = .02) and those aged between 8 and 12 years (P = .03) had significantly lower charges compared with those aged 18 years or older. Use of bone morphogenetic protein was associated with higher hospital charges (P = .0006). Compared with the uninsured, those covered by Medicaid (P = .04), private insurance plans (P = .02), and other insurance plans (P = .0005) were associated with higher charges.
This study identified an association between hospital charges and insurance payer, race, treatments performed, and age. Our results provide insights into nationally representative estimates on management of cleft palate corrections and revisions.

ABSTRACT: In order to investigate the toxicity of Ostreopsis species present in Greek coastal waters, cultures of Ostreopsis sp. and Ostreopsis ovata, mixed Ostreopsis field populations and shellfish collected from coastal waters of North Aegean Sea during late summer and autumn periods of 2004, 2005 and 2006 were examined by both mouse bioassay (MBA) and hemolysis neutralization assay (HNA). MBA testing was based on two different extraction protocols, while HNA also included the use of ouabain, a known palytoxin (PLT) antagonist. Results indicated the presence of a compound in both Ostreopsis cells and shellfish tissues, which was strongly toxic to mice. This compound exhibited characteristic symptomatology in mice (death, numbness, waddling gait and blindness) to that of PLT, as well as delayed hemolytic activity, which was neutralized by ouabain. HNA indicated that Ostreopsis cells contained a PLT-like compound (putative PLT, p-PLT) at concentrations ranging between 0.4 and 0.9 pg/cell, whereas concentration in shellfish tissues was estimated to range from about 33.3 to 97.0 microg p-PLT/kg tissue. To our knowledge, this is the first report of p-PLT contamination of shellfish by natural Ostreopsis species populations in European coastal waters and possibly globally, and also the first evidence on Ostreopsis cells' toxicity in the Eastern Mediterranean Sea.Toxicon 04/2008; 51(3):418-27. · 2.92 Impact Factor

ABSTRACT: Palytoxin has been isolated from the zoanthids "limu-make-o-Hana" (Tentatively identified as Palythoa sp.) as a noncrystalline, chromatographically pure entity. Apart from polypeptide and protein toxins, it is the most highly toxic substance known, with a lethal dose (LD(59)) in mice of 0.15 microgram per kilogram by intravenous injection. Unlike the potent toxins batrachotoxin, saxitoxin, and tetrodotoxin which have molecular weights of 500 or less, palytoxin has an estimated molecular weight of 3300 and contains no repetitive amino acid or sugar units.Science 05/1971; 172(3982):495-8. · 31.03 Impact Factor

ABSTRACT: Playtoxin, the toxin extracted from the soft coral Palythoa vestitus, Verril 1928, found in the Hawaiian and other Pacific Islands, is a highly lethal substance in several animal species, and is effective by various routes of administration. Its intravenous LD50 in the dog, rabbit, monkey, guinea pig, rat, and mouse range between 0·033 and 0·45 μg/kg. However, when palytoxin is given by the intragastric or intrarectal route, it is relatively non-toxic. Additionally, playtoxin produces marked irritant and tissue damage when topically applied to skin or eyes, as well as having a general necrotizing action on cells when injected.Toxicon. 01/1974;
