Question: Abstract: Distribution and elimination of cefamandole 2 g iv were studied in 11 morbidly obese patients during a gastric bypass operation and again on the first postoperative day. Serum, subcutaneous adipose tissue, wound drainage, and urine were analyzed by high performance liquid chromatography for cefamandole and pharmacokinetic parameters from the intraoperative period were compared to those obtained postoperatively. Total body clearance was significantly greater (p less than 0.001) postoperatively (297 ml/min) than intraoperatively (254 ml/min). Volume changes were unpredictable but the elimination rate constant tended to increase postoperatively. Renal clearance and percentage of urinary recovery were significantly increased (p less than 0.01) postoperatively. The patients had a mean (+/- SD) volume of the central compartment of 10.3 (+/- 2.3) L, volume at steady state of 18.3 (+/- 3.9) L, and elimination rate constant of 1.67 (+/- 0.63) h-1. Tissue concentrations of cefamandole were highest during the first hour after drug administration and were less than 1 microgram/g after 3.5 hours. Mean wound drainage concentrations ranged between 10 and 12 micrograms/ml during a dosing interval and dropped to 7 micrograms/ml 12 hours after the last dose. Intraoperative dosing of cefamandole is required to maintain subcutaneous adipose tissue concentrations greater than 1 microgram/g during procedures longer than three hours in morbidly obese patients. A postoperative dose of cefamandole 2 g iv q6h will provide sustained and therapeutic concentrations in the wound drainage of morbidly obese patients.

Answer: Cefamandole distribution in serum, adipose tissue, and wound drainage in morbidly obese patients.

Question: Abstract: We have studied the hematology, hemoglobin composition, and globin gene arrangements in one young Turkish boy with a beta zero-thalassemia homozygosity and in 11 of his relatives. Evidence is presented that the chromosome with the beta zero-thalassemia determinant carries a gamma-globin gene quadruplication, perhaps in a -G gamma-G gamma-G gamma-A gamma-gene arrangement. The eight gamma-globin genes in this patient produced G gamma and A gamma chains in a 95 to 5 ratio, and nearly 99% of the patient's hemoglobin was of the fetal type. The clinical condition resembled that of a thalassemia intermedia. HbF levels in eight beta-thalassemia heterozygotes varied between 0.5 and 4.2% and the percentages of G gamma in this HbF averaged at 87% or 95%; this level is to some extent related to the haplotype of the normal chromosome. All subjects carried four alpha-globin genes; a new BglII polymorphism was observed within the psi alpha-globin gene.

Answer: Beta zero-thalassemia in association with a gamma-globin gene quadruplication.

Question: Abstract: Recurrent pulmonary embolism from the lower extremities or pelvis, despite anticoagulation, often requires interruption of the inferior vena cava (IVC). We report two patients in whom interruption of the IVC failed to ameliorate symptoms. Both patients demonstrated a previously unrecognized duplication of the IVC. We stress the importance of excluding abdominal venous anomalies prior to interrupting the IVC using surgical or percutaneous methods.

Answer:
Duplication of the inferior vena cava in thromboembolic disease.
