With color Doppler imaging we attempted to quantify the retrobulbar hemodynamics in glaucoma patients with asymmetric visual field losses. The peak systolic and end-diastolic blood flow velocities and resistivity indices of the ophthalmic, short posterior ciliary and central retinal arteries were measured. We performed visual field examination, intraocular pressure (IOP) and blood pressure measurements. The study revealed reductions in the flow velocities and increases in the resistance indices of the retrobulbar vessels, despite similar intraocular pressure (IOP) curves in both eyes. These changes correlate with disease severity and asymmetry of visual field losses and illustrate a compromised retrobulbar hemodynamics. [ABSTRACT FROM AUTHOR]

Metastases to the skeletal muscle from breast cancer represent an unusual and rare condition. We present the case of a 27-year-old female with left breast cancer (IDC NST G3) who underwent neoadjuvant chemotherapy followed by conservativesurgery (sectorectomy and lymphadenectomy) and radiation therapy. Two months after the end of radiotherapy she presented with a 2 mm skin lesion and she was referred for a screening ultrasound. The screening automated breast ultrasound (ABUS) revealed local recurrence and pectoralis metastases, lesions evaluated also by magnetic resonance imaging. The diagnosis was confirmed by the ultrasound-guided biopsy.

Malaria was once endemic in the Osijek region of Croatia and although it has been eradicated, there are still several vector species of the Anopheles maculipennis complex in this area. During an eight-year investigation, using CDC traps with CO2 as an attractant, we collected a total of 3,508 mosquitoes. We determined the dynamics of members of this complex and found that they varied considerably with an average of two generations per season. Cross-correlations indicated that the Spearman's Index between the abundance rate and the water level was the highest 12 and 24 d before traps were set. This suggests that the long-term high water level created better conditions for continuous breeding of mosquitoes, which contributed to a significant increase in abundance rates of all species in the complex.

Background: Dialysis facilities have been introduced only recently in Transylvania with many limitations, in particular a standard high calcium dialysate, Al(OH)3 as phosphate binder and pharmacological doses of native vitamin D2, but neither CaCO3 nor 1 alpha hydroxylated vitamin D. Rheumatological complaints and metastatic calcifications were frequent, leading to suspect either overt hyperparathyroidism, adynamic bone disease or beta 2 microglobulin amyloidosis., Aims of the Study: Evaluate the prevalence of radiological osteitis fibrosa, amyloid osteoarthropathy and periarticular calcification and their link with PTH secretion, phophocalcic disorders, acidosis, bone turn over, aluminum and beta 2 microglobulin accumulation in the dialysis population of Sibiu (Transylvania)., Methods: The clinical and radiological rheumatological data of the 49 uremic patients dialyzed in Sibiu since 1990 were reviewed as well as the monthly routine monitoring of their plasma phosphocalcic parameters. Furthermore in July 1994, 36 of them had an X rays of the hands for evaluation of subperiosteal resorption of the phalanges, periarticular calcifications and carpal cysts as well as a determination of plasma concentrations of intact PTH (normal range: 10-55; optimal range: 100-200 pg/ml), osteocalcin, bone alkaline phosphatase, aluminum and 25 OH vitamin D., Results: The prevalence of subperiostal resorption of the phalanges was 8% and that of severe biological hyperparathyroidism (PTH > 400 pg/ml) 22%, whereas that of a relative hypoparathyroidism (PTH < 100 pg/ml) was 31%. Mean plasma concentrations of calcium was 2.07 +/- 0.15; of phosphate 2.50 +/- 0.35; of bicarbonate 15 +/- 2.0 mmol/l, of 25 OHD 30 +/- 20 ng/ml, of aluminum 1.1 +/- 0.5 mumol/l. Plasma PTH concentrations were negatively correlated to dialysis duration, and to plasma concentrations of aluminum, calcium and 25 OH vitamin D but not to those of phosphate and bicarbonate. Multivariate analysis showed however that only duration of dialysis and plasma aluminum concentration were independently and negatively correlated to plasma PTH concentrations. The prevalence of periarticular calcifications (26%) and of carpal cysts suggestive of beta 2 microglobulin amyloidosis (10%) were relatively high considering the young age of the population (42 years) and the short duration of dialysis (2.6 years). Patients with calcifications comparatively to those without calcifications were older, had longer duration on dialysis, higher prevalence of carpal cysts and higher plasma beta 2 microglobulin concentrations, lower plasma PTH (98 versus 313 pg/ml) and higher plasma aluminum concentration (1.3 versus 0.8 mumol/l). Patients with carpal cysts comparatively to those without cyst were older, had a longer duration on dialysis and a higher prevalence of periarticular calcifications., Conclusions: a) In spite of no use of 1 alpha hydroxylated vitamin D derivatives, and poor control of hyperphosphatemia and acidosis, hyperparathyroidism declined with duration of dialysis due to the use of a high dialysate calcium concentration, Al(OH)3 as sole phosphate binder and high supplement of native vitamin D. b) Considering the relative young age and short duration on dialysis, the prevalence of periarticular calcifications and carpal cysts were high. c) Calcifications were possibly favored by relative hypoparathyroidism and moderate aluminum overload. d) The association of periarticular calcifications and subchondrial cysts suggest a causal relationship.
