Long-term treatment with oral carotenoids in 57 patients suffering from a variety of photodermatoses and disorders associated with cutaneous light sensitivity was evaluated. All patients were treated for two or more 6-month periods in separate years. Best therapeutic results were seen in PMLE patients, a good to excellent therapeutic response was noted for 65% of all patients, increasing to 81% of those assigned to skin types III and IV, and decreasing to 47% of those with skin types I and II. The therapeutic effect observed in disorders characterized by other mechanisms than provocation by solar radiation per se was less conspicuous, viz. for light-sensitive psoriasis and lupus erythematosus. Even here, therapeutic failure seems to be more common in individuals with skin types I and II than for skin types III and IV. Photodermatoses such as persistent light reaction, actinic reticuloid and solar urticaria did not respond to any significant degree to carotenoid treatment. Our findings would appear to justify further treatment with oral carotenoids in selected cases of PMLE, and a higher dosage level may be tried for non-responding individuals with light-sensitive psoriasis and DLE or SLE. Serious side effects have not been observed in spite of long-term therapy lasting several years.

Morphine, an opium alkaloid, frequently causes side effects such as hyperhidrosis and facial flushing, but serious cutaneous adverse drug reactions are seldom observed. Best known are urticaria, erythema, and pruritus; sometimes pseudoallergic anaphylactoid reactions, and blisters are reported.

A 21-year-old male patient with no history of systemic disease or drug use presented to our clinic with redness and pain in the right eye. Best corrected visual acuity was 20/20 in both eyes. Inflamed pinguecula was observed on slit-lamp examination and the patient was prescribed ophthalmic nepafenac eye drops. After instilling the drops that day and the next day, the patient presented again due to pruritus and rash. Upon consultation with the dermatology department, the patient was diagnosed with drug-induced allergic urticaria and the nepafenac drops were discontinued. Although urticaria has been reported as a side effect after systemic non-steroidal anti-inflammatory drug (NSAID) use, such a reaction has not been reported with an ophthalmic NSAID and ours is the first reported case of urticaria following ophthalmic nepafenac use. This unique case highlights the fact that ophthalmologists must also keep urticaria in mind as a potential side effect when prescribing this drug.

Honey taken directly from 59 bee hives on the Hawaiian island of Kaua'i was analyzed for glyphosate residue using ELISA techniques. Glyphosate residue was detected (> LOQ) in 27% of honey samples, at concentrations up to 342 ppb, with a mean = 118 ppb, S.E.M. 24 ppb. Of 15 honey samples store-purchased on Kaua'i, glyphosate was detected in 33%, with a mean concentration of 41 ppb, S.E.M. 14. Glyphosate residue was not detected in two samples from the island of Molokai but was in one of four samples from the island of Hawai'i. Presence and concentration of glyphosate residues were geospatially mapped with respect to Hawaiian land divisions. Mapping showed higher occurrence of glyphosate that was over LOQ (48%) and concentrations of glyphosate (mean = 125 ppb, S.E.M. 25 ppb; N = 15) in honey from the western, predominantly agricultural, half of Kaua'i versus the eastern half (4%, mean = 15 ppb; N = 1). Geographic Information System analysis of land use percentage was performed within a circular zone of 1 Km radius around each hive. Various land use types within each circular zone were transcribed into polygons and percent land use calculated. Only agriculture land use showed a strong positive correlation with glyphosate concentration. High glyphosate concentrations were also detected when extensive golf courses and/or highways were nearby. This suggests herbicide migration from the site of use into other areas by bees. Best management practices in use for curtailing pesticide migration are not effective and must be carefully re-assessed.
