Hemorrhoidectomy--how I do it: experience with the St. Mark's Hospital technique for emergency hemorrhoidectomy.
Eighty-five patients who had thrombosed hemorrhoids underwent emergency hemorrhoidectomy according to St. Mark's Hospital technique, with very good results. All specimens were found to have dilated blood vessels filled with thrombi of different sizes, with irregular, fibrotic or hyalinized vascular walls. Early complications included urinary retention and painful defecation in some patients. Late complications included only skin tags. No sepsis was found among our patients. Although operative bleeding can be tedious during the hemorrhoidectomy, it was a complication in the postoperative period of only one patient. Segmental, open hemorrhoidectomy performed according to the St. Mark's Hospital technique has been shown to be an ideal operation for the treatment of patients who have hemorrhoidal thrombosis, prolapse, edema, and bleeding.

Successful correction of all mechanical complications of ischemic heart disease in the same patient.
Extensive surgery for all of the mechanical complications of ischemic heart disease is feasible with early diagnosis, catheterization, and aggressive medical and surgical therapy. A patient is report who, after recovering from cardiogenic shock, required a coronary bypass, closure of ventricular septal defects, mitral valve replacement, aneurysmectomy, and temporary pacemaker wires. The outcome was successful.

Biotransformation of furosemide in patients with acute pulmonary edema.
Furosemide (20-80 mg) was administered iv over 5 min to 16 patients with the diagnosis of acute pulmonary edema due to left heart failure. Serum and urine samples collected during the 24 hr after administration were assayed for furosemide and its biotransformation products by gas-liquid chromatography. A biexponential decay of serum furosemide concentrations vs. time was observed. Recovery of furosemide and its metabolites from urine in 24 hr varied between 30 and 98% of the administered dose. The excretion of unchanged drug accounted for 22.6-73.4% of the dose. The excretion of the glucuronide metabolite and 2-amino-4-chloro-5-sulfamoylanthranilic acid accounted for 3.3-40.4% and from 0.13-3.92% of the dose, respectively. Urinary excretion of furosemide was less in patients with, than in those without, myocardial infarction. Urinary excretion of the oxidative acidic metabolite was increased in patients with reduced creatinine clearance. The glucuronide metabolite of furosemide was the major biotransformation product in these patients with acute pulmonary edema.
