Retinal embolization during carotid angioplasty and stenting: periprocedural data and follow-up.

The purpose of this study was to prospectively evaluate the incidence of retinal emboli during carotid angioplasty and stenting (CAS) and to correlate emboli with clinical findings and transcranial Doppler (TCD)-detected cerebral embolic load. Between 2001 and 2005, 33 CAS procedures in 32 patients (23 [72%] male, 19 [58%] symptomatic, mean age 72.5 years [range 54.6 to 83.9]) scheduled for CAS were included in this study. Bilateral fundoscopy with retinal photography was performed by an experienced ophthalmologist immediately before, immediately after (fundoscopy only), and 1 day after the procedure and again at long-term follow-up (mean 37 months). Visual field testing was performed before CAS and again at long-term follow-up. TCD-detected cerebral emboli were stratified to five procedural phases: wiring, predilatation, stent placement, postdilatation, and cerebral protection device (CPD) use (if applicable). To establish correlation between TCD data and retinal embolization, Mann-Whitney test was used, and P < 0.05 was considered statistically significant. All procedures were performed successfully. In five of 33 procedures (15%), new retinal emboli were found. Two of the procedures with emboli had small retinal infarcts. Three of five were performed using CPDs versus seven of 28 that had no retinal emboli (P = not significant). Two of four patients (50%) with previous radiation therapy to the neck had new retinal emboli versus three of 29 patients (10%) who had no previous radiation therapy (P = 0.038). None of the other patient characteristics was associated with retinal embolization. In 30 (91%) of patients with an adequate acoustic temporal window for TCD monitoring, there was no statistically significant correlation between TCD data and the incidence of retinal emboli. No visual field defects were found. On long-term follow-up, all retinal emboli and retinal infarcts had resolved. Retinal embolization during CAS is not uncommon, and it occurs in both protected and unprotected procedures. Most retinal emboli are clinically silent.

[Favourable effect of lacrimal plugs after 3 and 9 months in 20 patients with severe sicca syndrome]. / Gunstig effect van traanbuispluggen bij 20 patiënten met ernstig siccasyndroom na 3 en na 9 maanden.

OBJECTIVE: To describe the results of the insertion of lacrimal plugs in patients with severe symptoms of dry eyes. DESIGN: Prospective descriptive study. METHOD: 20 patients who had severe symptoms of dry eyes despite topical therapy were included. The diagnoses were: 'primary Sjögren's syndrome' (n = 10), 'probably a primary Sjögren's syndrome' (n = 5) and 'secondary Sjögren's syndrome' (n = 5). Following a favourable subjective reaction to resorbable plugs, a non-resorbable silicone plus was inserted bilaterally into the openings of the inferior lacrimal ducts. During follow-up, the effect of treatment was assessed by means of various measurements of function of the lacrimal glands. RESULTS: After 3 and 9 months there was a measurable favourable effect with regard to tear production (Schirmer-test), tear film stability ('tear film break-up time'), the damage to the cornea (Bengal-red-test) and the subjective symptoms of dry eye on a visual analogue scale (VAS). The difference in comparison with the initial values was significant except for the Bengal-red-test after 9 months. There were no complications. In the 5 patients with a basal Schirmer test value of o mm after 5 min, there was no improvement.

Treatment of primary Sjögren's syndrome with D-penicillamine: a pilot study.

BACKGROUND: Up to now no satisfying systemic treatment is available for patients with primary Sjögren's syndrome. METHODS: In a prospective, open study we investigated the effect of D-penicillamine (first three months 250 mg/day, next three months 500 mg/day) on clinical and immunological parameters in 19 patients with primary Sjögren's syndrome and a mean disease duration of 3.8 years. RESULTS: Eight patients had to stop treatment mainly due to severe (reversible) loss of taste. Clinically, a statistically significant increase in basal salivary flow was observed after three months (p<0.05). In addition, improvement was noted in the Schirmer test and stimulated parotid salivary flow after six months, but these differences were not statistically significant. Laboratory values showed a decrease in ESR (p<0.05) and levels of IgA and IgM (both p<0.02) after six months, a decrease in levels of IgA-Rf and IgM-Rf after three months (both p<0.05), and an increase in haemoglobin level (p<0.05). CONCLUSION: From this pilot study we conclude that the treatment of primary Sjögren's syndrome with D-penicillamine has only marginal beneficial effects. Together with its clear side effects this means that D-penicillamine is unsuitable for this indication.

Bilateral sequential facial palsy during chickenpox.

UNLABELLED: Facial palsy is a rare neurological complication of chickenpox. A 5-year-old girl exhibited a right facial palsy followed by the appearance of the characteristic chicken pox exanthem. Subsequently she suffered a left facial palsy. In this patient both pathophysiological mechanisms responsible and their relation to the phase of infection are illustrated. CONCLUSION: Facial palsy as a complication of chickenpox can result from pre-eruptive haematogenous or neurogenous spread of varicella-zoster virus.
