Study of a kindred with thyroxine-binding globulin deficiency and oligomenorrhea.

The finding of a low total thyroxine level in an oligomenorrheic woman uncovered a new family with thyroxine-binding globulin deficiency and oligomenorrhea. Thirteen of 17 family members had the deficiency of thyroxine-binding globulin, with heterozygous female subjects showing overlap of levels with normal subjects. Oligomenorrhea was frequently found but segregated separately from the thyroxine-binding globulin deficiency; of seven women with low levels, three had normal monthly menstrual cycles. Fertility was not impaired.

Blood pressure studies in black children.

Blood pressure measurements were obtained under office conditions by auscultatory method, using appropriate cuff sizes, in 1,668 healthy black children (827 boys and 841 girls) ranging in age from 4 to 17 years. We found no significant difference between the mean systolic blood pressure of black children in our study and that of whites as reported in the literature. However, mean diastolic blood pressure was lower in black children. Some black children (3.6%) were found to have blood pressure more than 2 standard deviations above the mean for their age and should be closely observed for developing hypertensive cardiovascular changes.

Glaucoma-induced changes in the ciliary ganglion.

Changes in ciliary ganglion cells are described after the experimental induction of glaucoma in rhesus monkeys. They appear within 12 hours in the form of peripheral displacement or extrusion of the cell nucleus and loss of Nissl granules.

Increased formation of distinct F2 isoprostanes in hypercholesterolemia.

BACKGROUND: F2 isoprostanes are stable, free radical-catalyzed products of arachidonic acid that reflect lipid peroxidation in vivo. METHODS AND RESULTS: Specific assays were developed by use of mass spectrometry for the F2 isoprostanes iPF2alpha-III and iPF2alpha-VI and arachidonic acid (AA). Urinary excretion of the 2 F2 isoprostanes was significantly increased in hypercholesterolemic patients, whereas substrate AA in urine did not differ between the groups. iPF2alpha-III (pmol/mmol creatinine) was elevated (P<0.0005) in homozygous familial hypercholesterolemic (HFH) patients (85+/-5. 5; n=38) compared with age- and sex-matched normocholesterolemic control subjects (58+/-4.2; n=38), as were levels of iPF2alpha-VI (281+/-22 versus 175+/-13; P<0.0005). Serum cholesterol correlated with urinary iPF2alpha-III (r=0.41; P<0.02) and iPF2alpha-VI (r=0. 39; P<0.03) in HFH patients. Urinary excretion of iPF2alpha-III (81+/-10 versus 59+/-4; P<0.05) and iPF2alpha-VI (195+/-18 versus 149+/-20; P<0.05) was also increased in moderately hypercholesterolemic subjects (n=24) compared with their controls. Urinary excretion of iPF2alpha-III and iPF2alpha-VI was correlated (r=0.57; P<0.0001; n=106). LDL iPF2alpha-III levels (ng/mg arachidonate) were elevated (P<0.01) in HFH patients (0.32+/-0.08) compared with controls (0.09+/-0.02). The concentrations of iPF2-III in LDL and urine were significantly correlated (r=0.42; P<0.05) in HFH patients. CONCLUSIONS: Asymptomatic patients with moderate and severe hypercholesterolemia have evidence of oxidant stress in vivo.

Ocular cysticercosis.

Eight cases of ocular cysticercosis are reported. A rare case of cysticercus in the anterior chamber, and another case with bilateral involvement and two cysts in one eye are reported. The reasons for its prevalence in this region are discussed.

Prospective observational study of primary angioplasty of the infarct-related artery for acute myocardial infarction.

Primary angioplasty has been shown to reduce rates of in-hospital mortality, recurrent ischaemia and infarction. However, the role of primary stenting and abciximab is presently undergoing evaluation. This study attempted to examine the feasibility, safety and outcomes of primary angioplasty in the treatment of acute myocardial infarction. Data in 100 patients who underwent primary angioplasty for evolving acute myocardial infarction was prospectively analysed to assess the safety and efficacy of various modalities. Twenty patients were in Killip class III and above. Multivessel (2 or more vessels) disease was noted in more than 52 cases. Procedural success was 99 percent; 86 patients received primary stenting, majority of them had Kalam-Raju stent implantation. Adjunct treatment included abciximab infusion in 22 and intra-aortic balloon pump support in 12. Overall mortality rate was six percent with a mortality of 2.2 percent in non-cardiogenic shock patients. Recurrent ischaemic events were noted in five, three of them had successful reperfusion with repeat angioplasty. None of the patients had emergency coronary artery bypass surgery. It is concluded that primary angioplasty is safe and effective with high procedural success. Recurrent ischaemic events are low, possibly due to routine use of stenting and selective use of abciximab.
