Persistent light reaction is a condition of chronic photodermatitis in which photosensitive reaction persists even after the rernoval of all photosensilizers. A 56-year-old man had experienced a recurrent dermatitis involving primarily the face, neek, forearms and hands for 9 years, this condition was aggravated by sunexposure. Photopatch testing disclosed a strongly positive reaction to chloropromazine, promethazine, acid trichlorocarbanilide, Phototesting also revealed lowered MED with UVA and UVB thar norrmal mean value.

In order to elucidate the mast cell changes challenged by various antihistaminic preparations and its role to the mast cells challenged by inflammation, male albino rats weighing 120-130gm were used for this investigations. Benadryl hydrochloride, Phenergan hydrochloride and Chlor-Trimeton maleate were choosed for antihistaminic challengers and ultraviolet ray was irradiated for an inflammatory challenger. 1. When rats were challenged by various antihistaminics the numbers of mast cell reached to the least after 2 days and later followed by an increasing mast cell numbers. 2. The mast cell changes were severer in order of Phenergan hydrochloride, Benadryl hydrochloride and Chlor-Trimeton maleate. 3. Degranulated mast cell was proportionally increased as the numbers of mast cell decrease after being challnged by antihistaminics and also it was decreasing when the numbers of mast cell were re-increasing

BACKGROUND: Chronic actinic dermatitis (CAD) is a rare disease worldwide. It has been defined on the basis of three criteria: 1) clinical - a persistent eczematous eruption on sun- exposed area with possible extension into non-exposed areas, 2) photobiological - a reduction in the minimal erythema dose to UVB irradiation, and possibly longer wavelengths, and 3) histologic - an appearance consistent with chronic eczema, with or without the presence of lymphoma-like changes. However, only a few clinicohistopathologic and photobiological analyses of CAD have been undertaken in Korea. OBJECTIVE: To explore photoallergens and/or allergens causing or thought to be associated with CAD in Korean patients, and to compare the photopatch or patch test results in Korea with those from other countries. METHODS: Thirty-five Korean patients with CAD were enrolled for this study. Photopatch tests were carried out by applying two sets of the Scandinavian photopatch series to each patient. Two days after application, the photopatch tests were analysed, and one set of the photoallergens was irradiated with 50% of the MED-UVA. Both sets of photoallergens were examined 2 days later. A European standard series was used to assess the patch tests. At two and four days after application, patch tests were analysed. RESULT: Twenty-seven of the 35 patients (77.1%) who had photopatch tests showed positive responses; balsam of Peru, promethazine HCl, perfume mix, fentichlor, chlorhexidine digluconate, and chlorpromazine HCl were the common photoallergens that elicited a positive response. Twenty-one of the 35 patients (70%) showed allergy to nickel, chrome, and/or ammoniated mercury. Noticeably, photoallergens such as balsam of Peru, perfume mix, cobalt, and captan revealed positive reactions in the patch tests, too. CONCLUSION: In 77.1% and 74.3% of CAD patients, photoallergens and allergens were identified, respectively. Among them, 57.1% showed positive reactions including both photopatch and patch tests. After the most frequent photoallergens, perfume and spices, and phenothiazines or related antihistamines ranked next and were found to be a unique characteristic to Korea. Photopatch and patchtests are the method for detecting photoallergens and allergens as important initiating agents and are the diagnostic tool for the epidemiologic study of CAD.

Thirty-two adult female ASA I patients (American Society of Anesthesiologists' grading) undergoing voluntary termination of pregnancy (VTP) under general anaesthesia were randomly divided into three groups. Patients received 0.6 mg/kg pentazocine intravenously five minutes prior to induction of anaesthesia along with either isotonic saline, or promethazine 0.5 mg/kg or metoclopramide 0.2 mg/kg. Anaesthesia was induced with intravenous thiopentone and maintained with nitrous oxide in oxygen and boluses of thiopentone. Vomiting and sedation were scored at the end of anaesthesia, one hour later and at the time of discharge. The mean vomiting score was comparable in the three groups. Though the mean dose of thiopentone used was significantly less in the promethazine group, the sedation scores and the duration of stay in the clinic were comparable in all the groups. It is concluded that promethazine and metoclopramide in the doses used are ineffective as antiemetic agents in outpatient gynaecological patients.

BACKGROUND: Deficiencies in anaphylaxis management in Emergency Departments is well recognised despite established guidelines for its treatment. OBJECTIVE: To identify deficiencies in the management of anaphylaxis in a busy metropolitan Emergency Department and determine if an education intervention could correct these. METHODS: Paediatric and adult admissions to the Emergency Department of a busy hospital were tracked over a 10-month period with a targeted educational program being instituted at 5 months. The electronic records were retrospectively reviewed looking for cases of anaphylaxis and milder forms of immediate type allergic reactions presenting with a combination of urticaria and nonairway threatening angioedema. Anaphylaxis presentation was graded using the Brown grading system. Use of all medication during resuscitation was documented. Observation period before discharge and referral to specialist unit for follow-up was noted. RESULTS: In the first 5 months, 38 patients fulfilled our criteria. Three had severe anaphylaxis, 13 had moderately severe anaphylaxis and 12 had urticaria and angioedema without anaphylaxis. Anaphylaxis was not always recognised or graded leading to inappropriate management with adrenaline often being withheld. Promethazine, usually given in parenteral form, was frequently administered. Observation time was often inadequate. Referral to an immunologist was not universally followed through. Following the educational intervention 58 patients fulfilled our criteria over the next 5 months. The appropriate use of adrenaline increased by 21% and the use of sedating antihistamines decreased by 16%, while the number of referrals to an immunologist increased by 24%. There was an 11% reduction in the number of patients who were observed for at least 4 hours. CONCLUSION: A number of deficiencies in the management of anaphylaxis presentations have been identified. Targeted educational activities aimed at the Emergency Department hospital staff may improve outcomes.

This paper reports the establishment of a method for rapid identification 15 effective components of anti common cold medicine (paracetamol, aminophenazone, pseudoephedrine hydrochloride, methylephedrine hydrochloride, caffeine, amantadine hydrochloride, phenazone, guaifenesin, chlorphenamine maleate, dextromethorphen hydrobromide, diphenhydramine hydrochloride, promethazine hydrochloride, propyphenazone, benorilate and diclofenac sodium) with MRM by LC-MS/MS. The samples were extracted by methanol and were separated from a Altantis T3 column within 15 min with a gradient of acetonitrile-ammonium acetate (containing 0.25% glacial acetic acid), a tandem quadrupole mass spectrometer equipped with electrospray ionization source (ESI) was used in positive ion mode, and multiple reaction monitoring (MRM) was performed for qualitative analysis of these compounds. The minimum detectable quantity were 0.33-2.5 microg x kg(-1) of the 15 compounds. The method is simple, accurate and with good reproducibility for rapid identification many components in the same chromatographic condition, and provides a reference for qualitative analysis illegally added chemicals in anti common cold medicine.
