Cardiovascular risk factors in the population of 2 regions covered by the MONICA-France regions: Strasbourg and Toulouse

Cardiovascular risk factors were studied from 1985 to 1987 in two population samples from the French regions of the Bas-Rhin (BR) (Strasbourg) and the Haute-Garonne (HG) (Toulouse). 1,257 men and women in the BR and 1,323 in the HG, aged 35-64, participated in the survey. A common investigation methodology in harmony with the MONICA protocol, was used. The mean weight was higher among the male (5 kg) and female (6 kg) populations living in the BR than in the HG. Even after age, body mass index and tobacco consumption adjustments, arterial systolic blood pressure was higher in the male population of the BR (145 mm Hg) than in the HG (133 mm Hg). Similar differences were observed among the female population. A higher proportion of hypertensive subjects whatever the sex and the age group was noted in the BR. The proportion of smokers, and the quantity of tobacco they smoked, did not differ between the two centers. Adjusted total cholesterolemia was higher in the HG, with mean differences of 0.32 mmol/l among the men and 0.35 mmol/l among the women. In the case of HDL cholesterol, the differences were 0.23 mmol/l among the men and 0.34 mmol/l among the women, explaining in large part the differences of the mean levels of total cholesterol.     

Experimental epikeratophakia using tissue lathed at room temperature.

This report presents for the first time the results of carrying out epikeratophakia with tissue lathed at room temperature. Using an experimental model of epikeratophakia in the rabbit, we evaluated tissue handling techniques for the preparation of donor lenticules. Details of the technique are described and the in-vivo and histopathological findings reported.     

Neonatal Graves'' disease.

A newborn boy was noted by his mother to have a prominent left eye at birth, but an eye examination was delayed until age 7 months, at which time his ophthalmologist diagnosed exophthalmos. Computed tomography was interpreted as showing mild, diffuse, optic nerve thickening bilaterally suggestive of optic nerve gliomas. Subsequent examination in our clinic revealed pseudoproptosis secondary to retraction of the left upper eyelid. Magnetic resonance imaging demonstrated normal orbital structures. The mother was noted to be clinically hyperthyroid, and abnormal thyroid function tests confirmed the diagnosis. Although the infant was euthyroid, neonatal Graves' ophthalmopathy was diagnosed. He was managed by close observation while his mother was treated for her hyperthyroidism.     

Parapapillary diameter of retinal vessels. I. Estimating the size of the optic papilla (a papillometric study of over 264 normal eyes)

The diameter of the temporal superior and inferior retinal artery and vein were measured at the optic disk border and 2 mm from the disk center in 264 nonselected normal eyes on the basis of photographs, with correction of magnification. Additionally, the individual ocular magnification factor was determined by Littmann's method. The mean caliber of the artery was 0.113 +/- 0.019 mm at the disk border and 0.118 +/- 0.023 2 mm from the disk center. The corresponding values for the vein were 0.149 +/- 0.026 mm and 0.159 +/- 0.026 mm. The correlations between vessel caliber and disk size were not significant, but the relationship between disk size and the quotient of vessel diameter divided by disk size was highly significant (p less than 0.0001). Vessel diameter can therefore be taken as an independent unit for determining optic disk size in relative and approximately also in absolute units. Thus, mean horizontal disk diameter (1.77 +/- 0.33 mm) corresponded to 16.3 +/- 3.5 artery and 12.3 +/- 2.6 vein diameters (measured at the optic disk border). The mean individual ocular magnification factor was 0.302 +/- 0.017, with a Gauss standard distribution. If the optical characteristics of a photographed eye are not known and the ocular magnification factor is assumed to be 0.302, then 68.3% of all eyes will be covered with an inaccuracy of 5.6% and 95.5% of all eyes with an inaccuracy of 11.2%.     

Ocular involvement in mycotic sinusitis caused by Bipolaris

We examined two patients with unilateral ophthalmologic findings secondary to pansinusitis caused by Bipolaris. Both patients were healthy young men. One patient had a gradual visual loss, whereas the other showed proptosis. Surgical debridement was the primary treatment in both patients. One patient received antifungal therapy, whereas the other was cured with surgery alone.     

Three months of octreotide treatment decreases gastric acid secretion and argyrophil cell density in patients with Zollinger-Ellison syndrome and antral G-cell hyperfunction

Methods: The effects of three months of treatment with octreotide on gastric acid hypersecretion induced by hypergastrinaemia were investigated in patients with Zollinger-Ellison syndrome (n= 5) or antral G-cell hyperfunction (n= 4). Gastric acid secretion, fasting plasma gastrin concentrations and clinical findings were examined, and a morphometrical analysis of oxyntic endocrine cells was performed. Results: Administration of octreotide 100 meg b.d. subcutaneously significantly decreased the volume density of argyrophil cells (P < 0.05) as well as basal and pentagastrin-stimulated acid secretion (P < 0.05). Although partial or complete loss of inhibition was found in most patients after 3 months, gastrin levels were decreased during the first 2 months of treatment (P < 0.05). Fundic D-cells were not affected by treatment. Positive correlations were observed between volume density of argyrophil cells and basal acid output (r= 0.65); plasma gastrin and basal acid output (r= 0.74); plasma gastrin concentrations and volume density of argyrophil cells (r= 0.80). Conclusion: These results support the important role of the enterochromamn-like cell in maintaining acid secretion, and indicate a specific role for octreotide in the therapy of gastric acid hypersecretion associated with hypergastrinaemic diseases.
