    Notes: Abstract A 54-year-old black female presented with proptosis and reduced visual acuity of the left eye. Computerized tomography (CT) revealed tumor involvement of the left cavernous sinus and posterior orbit. The patient had a nineteen year history of a left-sided jaw tumor which recurred despite surgical and radiation therapy. Biopsy demonstrated a parakeratinized odontogenic keratocyst with areas of transformation into an invasive squamous cell carcinoma. Although a parakeratinized odontogenic keratocyst may be locally invasive, to our knowledge, no case of a parakeratinized odontogenic keratocyst involving the orbit or cavernous sinus previously has been reported.

    Use of the argon laser to close filtering bleb leaks (1992)
    Springer
    Graefe's archive for clinical and experimental ophthalmology 230 (1992), S. 537-541

    Notes: Abstract We attempted to seal 15 consecutive filtering bleb leaks in 11 patients using argon laser energy. Eight leaks were at the conjunctival-corneal interface associated with a fornix-based flap, 4 leaks resulted from suture scissoring of the conjunctiva, and 3 leaks were button-holes in the conjunctiva. Thirteen leaks occurred within 2 weeks after filtering surgery, while 2 were of late onset. Argon laser parameters used were a 500-μm spot size, 0.1-s time interval, and between 500 and 1800 mW of power. Thirteen leaks were sealed after one or two laser sessions, while 2 leaks required other treatment modalities. Complications included conjunctival fenestration and transient corneal stromal opacities. This study suggests that the argon laser can be used to seal filtering bleb leaks in many patients following filtering surgery.

    A sensitive method for determining the nephrotoxic effects of the analgesic acetaminophen upon esterases using isoelectric focusing (1981)
    Weinheim : Wiley-Blackwell
    Electrophoresis 2 (1981), S. 187-190

    Notes: In a study of the biochemical mechanisms of renal toxicity of acetaminophen, quantitative studies of the nonspecific kidney esterases were carried out in New Zealand white female rabbits. After the administration of a sublethal dose of 2.5 g/kg acetaminophen, four animals each plus four controls were sacrificed at 24 and 48 h. subsequent isoelectric focusing of kidney homogenate supernatants over a pH range of 3.5-8.0 showed marked changes in each of the groups. Zymograms of the nonspecific esterases in each group showed a characteristic pattern which deviated greatly from control animals. A morphological and histochemical examination of kidney sections from all animals showed no pathological changes in any of the kidneys. This would indicate that abnormal biochemical changes are being manifested in the kidney long before any morphological deviations. It would seem that this group of enzymes could provide a valuable market for early toxicological changes.
