Endophthalmitis following cataract surgery in Sweden: national prospective survey 1999-2001.

Purpose: To investigate the epidemiology of postoperative endophthalmitis (POE) following cataract surgery in Sweden during a 3-year period, using the framework of the Swedish National Cataract Register.

Methods: Clinically presumed cases of POE were reported in a prospective survey involving all Swedish ophthalmic surgical units except one. Data on results of the intraocular culture and visual outcome after infection, as well as patient age and gender and various elements of the surgical procedure, were collected.

Analysis of a device for assessment of abutment and prosthesis screw loosening in oral implants.

Screw loosening is an irritating problem in implant dentistry. Loosened abutment screws and prosthesis screws are often found at yearly examinations. Loosened screws may cause costly complications, such as screw fractures and fracture of the framework, and methods to prevent them would be welcome.

Endophthalmitis following cataract surgery in Sweden. The 1998 national prospective survey.

Purpose: To investigate the morbidity of postoperative endophthalmitis (POE) following cataract surgery in Sweden in 1998.

Methods: Clinically presumed cases of POE were reported in a prospective survey in which all Swedish ophthalmic surgical units except one had agreed to participate. Data on intraocular cultures and visual outcomes at 3 months after infection were supplied.

Similar T helper Th2-like cytokine mRNA expression in vernal keratoconjunctivitis regardless of atopic constitution.

Background: Many patients with vernal keratoconjunctivitis (VKC), a severe chronic allergic eye disease in children, exhibit IgE-sensitization, but about 40% of cases lack this immunologic trait. As a disease factor in VKC, IgE is thus not fully understood. The aim of this study was to investigate whether there are any differences in the conjunctival cytokine messenger (m)RNA pattern related to IgE-sensitization in children suffering from VKC.

Respiratory syncytial virus and chlamydia are not detectable by PCR in ongoing vernal keratoconjunctivitis.

Respiratory syncytial virus (RSV) and chlamydial infection may be pathogenetic factors in allergic diseases, perhaps also in ocular allergy. We analyzed the presence of RSV and chlamydial nucleic acids using reverse transcription (RT)-PCR and PCR, respectively, in conjunctival biopsies from patients with vernal keratoconjunctivitis (VKC) in order to determine whether these agents play a role in the maintenance of the disease. All biopsy samples were negative for both RSV (n = 15 for VKC and n = 10 for control subjects) and chlamydia (n = 8 for VKC and n = 7 for control subjects) homologous sequences.

Preoperative gentamicin eye drops and chlorhexidine solution in cataract surgery. Experimental and clinical results.

Purpose: 1) To evaluate the effects on the conjunctival flora of gentamicin ophthalmic eye drops 0.3%, given four times in 45 minutes, and a conjunctival rinse with 10 ml chlorhexidine 0.05% solution.

Exfoliation syndrome and the effect of phenylephrine and pilocarpine on pupil size.

The horizontal diameter of the pupil was measured on 20 eyes with exfoliation syndrome and 20 control eyes before and after the instillation of 10% phenylephrine and 4% pilocarpine eye drops. Pupil dilation induced by topical application of the alpha 1 adrenoceptor agonist phenylephrine was significantly smaller in eyes with exfoliation syndrome compared to controls. The cholinergic agonist pilocarpine decreased pupil diameter and this effect was significantly less in cases with exfoliation syndrome.

Testicular hydrocele treated by bismuth phosphate injection.

Thirty-eight testicular hydroceles were treated by injection with 0.2-0.4 g of bismuth phosphate.

Absorption and elimination of mannitol solution when used as an isotonic irrigating agent in connection with transurethral resection of the prostate.

12 patients were studied in connection with transurethral resection of the prostate using the intermittent technique and isotonic 5% mannitol solution as an irrigating fluid. No diuretics were given postoperatively. The serum creatinine concentrations were normal in 10 patients and slightly elevated in 2.

Plasma haemoglobin concentrations and other influx variables in blood in connection with transurethral resection of the prostate using distilled water as an irrigating fluid.

Eight patients undergoing transurethral resection of the prostate (TURP) using sterile distilled water as an irrigating fluid were studied. The concentrations of plasma haemoglobin, serum sodium, serum prostatic acid phosphatase protein (PAP) and plasma osmolality were determined as possible indicators of absorption of irrigating fluid. In 3 patients there was a marked increase in plasma haemoglobin immediately postoperatively with a maximum of 3.

The effect of stress hormones on the interorgan flux of amino acids and on the concentration of free amino acids in skeletal muscle.

Plasma concentrations of free amino acids have previously been found to decrease posttraumatically and this decrease can be reproduced by infusion of stress hormones. The mechanisms underlying this effect has not been investigated and therefore 14 healthy subjects were studied by infusing adrenaline alone or a combination of adrenaline, glucagon, and cortisol, in dosages giving pathophysiological plasma concentrations of the hormones. The influence on the interorgan fluxes of free amino acids and on the concentrations of free amino acids in skeletal muscle were determined.

The diurnal pattern of protein synthesis in human skeletal muscle.

The diurnal pattern of protein synthesis in skeletal muscle was studied in relation to the serum concentrations of glucose, insulin and cortisol. Twelve healthy volunteers were given an ordinary hospital diet at 4-hourly intervals. The concentration of insulin showed peaks in response to food intake, and that of cortisol decreased over the day.
