Early myocardial revascularization for postinfarction angina: results and long-term follow-up.

Within 30 days of acute myocardial infarction, 108 consecutive patients underwent urgent surgical myocardial revascularization for postinfarction angina between July 1976 and March 1983. There were 84 men and 24 women whose mean age was 59.6 +/- 9.

Phthisis bulbi after intraocular lens implantation in a child.

A 4-year-old boy with trisomy 21 and a congenital cataract underwent cataract extraction and implantation of an iris-supported intraocular lens (IOL). Four years later the implant dislocated anteriorly and had to be removed. Now, 11 years postoperatively, the eye is blind, painful and shrunken.

The kinetics of D3-3H metabolism in tropical sprue.

The metabolism of vitamin D3-3H was studied in a small group of controls and subjects with tropical sprue after the oral or intravenous administration of 8 to 10 microCi of D3-3H. The biological half life of D3-3H upon the administration of the isotope by the intravenous route was normal in 2 controls, very low in a subject with tropical sprue who had steatorrhea, and decreased in a subject with tropical sprue who did not present steatorrhea. After the administration of the isotope by the oral route, the biological half life was 35 hours in the control and no radioactivity could be detected in the plasma of the subject with tropical sprue who had steatorrhea.

Carpentier's flexible ring versus De Vega's annuloplasty. A prospective randomized study.

To compare the efficacy of Carpentier's tricuspid annuloplasty with De Vega's, we prospectively randomized 159 patients, operated upon between January, 1977, and January, 1980, to one of the two techniques: 76 patients were assigned to the Carpentier group and 83 to the De Vega group. The criterion for inclusion in the study was the presence of moderate to severe tricuspid regurgitation. There were no significant differences in mean age, male proportion, type of mitral lesion, incidence of aortic valvulopathy, and other preoperative and perioperative characteristics between the two groups.

Effects of intertrial interval, orientation, and adaptation on orientation discrimination measured with a yes-no signal detection paradigm.

Orientation discriminations were measured with a 3.8-cpd sinusoidal grating stimulus and a yes-no signal-detection procedure. Analysis showed that such discriminations are independent of light-adaptation conditions and of intertrial interval over the 2- to 8-sec.

The use of biodegradable norethisterone implants as a 6-month contraceptive system.

The effects of a 6-month contraceptive system of biodegradable norethisterone (NET) implants on the menstrual cycle, estradiol and progesterone levels, the presence of side effects, its contraceptive effectiveness, and the NET levels achieved were studied in a group of nine women. There was practically no disruption of the menstrual cycle and no important side effects. Ovulation was inhibited in four subjects, and another four subjects remained ovulatory.

The Medtronic-Hall prosthesis in multiple valve replacement--first results.

From January 1981 to September 1982, 107 patients have been operated on for valve replacement with the Medtronic-Hall (M-H) prosthesis. Thirty-four of them have had multiple valve replacements and they are the subject of this paper. In 2 cases there were tricuspid replacement, and in 9 other patients some type of tricuspid annuloplasty was performed.

The effects of three different regimens of oral contraceptives and three different intrauterine devices on the levels of hemoglobin, serum iron and iron binding capacity in anemic women.

The effects on hemoglobin, iron and iron binding capacity (IBC) in 150 moderately anemic women of 1) a 21-day low-dose combined pill, 2) the same low-dose combined pill for 21 days, followed by 7 days of an iron-containing pill, 3) the same low-dose combined pill administered for 63 consecutive days, followed by 7 days of no pill intake, 4) Lippes IUD, 5) TCu 220C and 6) Progestasert were studied. The three pill regimens were associated with an increase in hemoglobin and serum iron after 12 months. However, the iron pill and 63-day schedule groups produced an increase in hemoglobin and iron at the 6th month ans a diminution of IBC at 12 months.

Treatment of adult acute lymphoblastic leukemia with adriamycin, vincristine, and prednisone.

At the present time, it is possible to achieve up to a 95% complete remission in childhood acute lymphoblastic leukemia, using the combination of vincristine and prednisone. Nevertheless, it has not been possible to reproduce these results in the adult. For this reason, a third drug, in this case adriamycin in a low dose, was added to the vincristine-prednisone combination in the treatment of adult acute lymphoblastic leukemia (ALL).

Bioavailability of iron- and copper-supplemented milk for Mexican school children.

Fortification of dairy products with trace metals requires use of assimilable compounds that do not catalyze off-flavors due to lipid peroxidation but show good biological availability. The Fe(III) and Cu(II) chelates of the promising chelator, lactobionic acid, have been compared to Fe(II) and Cu(II) salts for their ability to improve hematological status in a mildly anemic population. Fe- and Cu-fortified cow milk was administered to children (aged 6 to 15) in the Durango, Mexico, "school lunch" program.
