The currently recognized toxic effects of quinine in humans are identified and the problems of management of overdosage of quinine are discussed. Quinine, available therapeutically as sulphate or hydrochloride salts, also is widely used in tonic water, and there are several case reports of allergic reactions to the drug when a patient has consumed the drug in this way. Another unintentional source of poisoning is its use as an adulterant in heroin for "street" use. This appears to be a problem in the US. Quinine, termed a "general protoplasmic poison" is toxic to many bacteria, yeasts, and trypanosomes, as well as to malarial plasmodia. Quinine has local anesthetic action but also is an irritant. The irritant effects may be responsible in part for the nausea associated with its clinical use. In addition it has a mild antipyretic effect. Several features are common to both an acute single overdose in self-poisoning and accumulation of quinine during therapy for malaria: together they are termed cinchonism. Auditory symptoms, gastrointestinal disturbances, vasodilatation, sweating, and headache occur with moderately elevated plasma quinine concentration. As these rise, increasingly severe visual disturbances and then cardiac and neurologic features occur. Mild nausea may be the only symptom, but with large overdoses profuse vomiting, abdominal pain, and diarrhea may occur. These result from a combination of the local irritant effect of quinine on the gut and the central effects of quinine on the chemoreceptor trigger zone. Vasodilatation and sweating are well recognized, and tinnitus is common. Visual symptoms usually are delayed, and blindness may not be discovered for a day or more. Aspirin-sensitive patients, and others, may develop angioedema by nonimmunological mechanisms in response to drugs, and quinine has been reported to produce pseudo-allergic reactions in aspirin-sensitive patients. Quinine also can cause drug-induced thrombocytopenia and purpura. In patients suffering with malaria due to "Plasmodium falciparum," anemia and acute intravascular hemolysis with renal failure are recognized complications. There appears to be little evidence in the literature in support of the folk tradition of quinine as an inducer of abortion. Quinine is known to cause deterioration in patients with myasthenia gravis and erythema multiforme, to stimulate insulin release in patients receiving treatment for falicparum malaria, and to be responsible at times for ataxia following moderate overdosage. Clinically, quinine poisoning is observed in 3 situations: self-poisoning; accidentally; and following use of quinine in excessive doses in the hope of achieving abortion. Treatment courses are reviewed.

Dapsone has been used since 1976 in the treatment of relapsing polychondritis. A critical analysis of its therapeutic effectiveness based on 2 personal cases and 14 cases reported in the literature, all treated with dapsone alone, showed that treatment had to be discontinued in 4 on account of side effects (haemolytic anaemia, erythema multiforme, somnolence, headache, nausea); 1 patient showed no improvement and 5 relapsed; 6 responded favourably and without relapse during a 3 months' to 4 years' follow-up. Considering the unpredictable course of relapsing polychondritis and the fact that some of its clinical manifestations, notably auricular chondritis, may spontaneously resolve, the response of the disease to dapsone is difficult to establish and requires to be confirmed by a controlled clinical trial.

A prospective study was carried out to assess the occurrence and character of adverse cutaneous reactions in patients receiving ticlopidine hydrochloride to prevent subacute thrombosis after having undergone placement of coronary stents. During a 1-year period such patients were requested to report any adverse cutaneous reactions, and those with skin reactions were referred for dermatological evaluation. Among the 136 patients who underwent stent placement by one of the authors, 20 were referred for dermatological evaluation. Of these, 16 (11.8%) fit the case definition of ticlopidine-associated cutaneous reactions. In the first 8 consecutive patients ticlopidine was withdrawn (in 2 of these a rechallenge test was later performed); in the next 8 patients ticlopidine was not discontinued before completion of the intended 4-week period of treatment. Patients remained under weekly follow-up and underwent a weekly blood count. Skin biopsies were obtained in 5 patients with different types of eruptions. The skin reactions appeared from 2 to 21 days after commencement of ticlopidine (mean, 10 days), lasting from 2 to 30 days (mean, 5 days). Only 3 patients had other adverse effects: neutropenia in 1 and abdominal pain and nausea in 2. The most common presentations were urticaria, pruritus, and maculopapular eruption. In 3 patients there were previously unreported reactions: fixed drug eruption, erythromelalgia-like eruption, and erythema multiforme-like eruption. Of note was the rapid clearing of the skin eruption in most cases even when the drug was not withdrawn. It was concluded that adverse cutaneous reactions are relatively common in association with ticlopidine treatment but that serious reactions are rare and the disappearance of the signs and symptoms is rapid, suggesting that discontinuation of the drug is not usually imperative.

Alendronate sodium is an aminobiphosphonate, an analog of inorganic pyrophosphate, indicated for the treatment of osteoporosis in post-menopausal women. We analyzed events reported in patients prescribed alendronate by general practitioners (GPs) in England. A non-interventional observational cohort study was conducted using the technique of prescription event monitoring (PEM). Exposure data were obtained from dispensed prescriptions issued between October 1995 and January 1997. Outcome data were obtained by sending questionnaires to prescribing GPs. The cohort comprised 11,916 patients. Events most frequently reported as suspected adverse drug reactions and reason for stopping alendronate were recognized gastrointestinal events listed in the Summary of Product Characteristics. These included nausea/vomiting, abdominal pain, dyspepsia, esophagitis and esophageal reflux. Events with the highest incidence density (ID(1) per 1000 patient months treatment) were dyspeptic conditions (32.2), nausea/vomiting (20.8) and abdominal pain (13.8). The term dyspeptic conditions included dyspepsia, esophagitis, esophageal reflux, duodenitis, gastritis and heartburn. Serious suspected adverse reactions possibly related to alendronate were single reports of angioedema, erythema multiforme, hypercalcemia and hypocalcemia. There were 540 deaths in this elderly cohort. This study suggests that alendronate appears to be well tolerated, though there may be risk of developing gastrointestinal side effects including esophagitis and esophageal ulcers.

Levamisole, an anthelmintic agent with a wide range of immunomodulatory actions, has been used successfully as monotherapy and an adjunct to treatment in a variety of diseases. Since 1990, combination therapy of levamisole and fluorouracil has played an important role in the treatment of resected Dukes stage C adenocarcinoma of the colon. Because of its immunomodulating effects levamisole has been used in a wide range of diseases with and without success. In dermatologic disease levamisole has been successfully used in the treatment of parasitic, viral and bacterial infections including leprosy, collagen vascular diseases, inflammatory skin diseases and children with impaired immune a variety of reasons. It has also been used in combination with other drugs for treating a number of dermatologic disorders, e.g. in combination with cimetidine for treating recalcitrant warts, with prednisolone for treating lichen planus, erythema multiforme and aphthous ulcers of the mouth. Adverse affects of levamisole are mild and infrequent and include rash, nausea, abdominal cramps, taste alteration, alopecia, arthralgia, and a flu-like syndrome. It can rarely cause agranulocytosis. More studies need to be undertaken to study the full potential of levamisole in dermatologic diseases.

Autoimmune progesterone dermatitis (APD) is rare autoimmune response to endogenous progesterone or to earlier exposure to exogenous progesterone (1). Skin lesions typically occur due to increases in progesterone during the luteal phase of the menstrual cycle (2). A-31-year-old mother of two children presented to our Department with a 5-year history of pruritic and painful erythematosus macules, papules, and patches on her neck, pectoral region, and face, which appeared 2-3 days before the onset of menses and gradually resolved 7-10 days later (Figure 1). The lesions first appeared 10 months after her second pregnancy and a few months after she had started using oral contraceptive pills (OCP) containing gestodene combined with ethinyloestradiol. A few months before presenting to us, the lesions had started spreading on her forearms, elbows, and pretibial areas. Since one year prior to our visit she had complained of occasional urticaria with angioedema one week prior to menses, which resolved after menses. The lesions were accompanied by malaise, headache, and fatigue. The patient was asymptomatic between the outbreaks. She reported that she had been using various local corticosteroids, peroral antihistamines, and prednisone for the treatment of her skin lesions, but this treatment had not improved her symptoms. She suffered from mild seasonal rhinoconjunctivitis. We performed multiple laboratory tests that were unremarkable. Histopathological examination of a biopsy taken from a lesion on the neck showed epidermal hyperplasia and nonspecific mild dermal inflammation. Since progesterone was not available in aqueous solution in our country, we did not perform an intradermal test, but we performed a lymphocyte transformation test (LTT) to medroxyprogesterone and estradiol. The patient's lymphocytes showed markedly enhanced proliferation to medroxyprogesterone in vitro, while being negative to estradiol. We had performed control LTT in 10 healthy controls and 10 patients with atopy, and such hyperactivity was not observed in any of them. We performed an oral provocation test with OCP containing gestodene combined with ethinyloestradiol. Two days after commencing treatment, the patient developed widespread dermatitis (Figure 2) with nausea, malaise, and angioedema. The patient was informed about treatment options and possible side-effects. She started with OCP with the lowest amount of progesterone, containing ethinyloestradiol and dropirenone for treatment of APD, but terminated treatment after the second cycle due to a worsening of the skin lesions and urticaria accompanied with angioedema. At the time of writing, our patient continues to have premenstrual flares. The typical symptoms of APD are skin lesions such as eczema, erythema multiforme, prurigo, stomatitis, papulopustular lesions, folliculitis, urticaria, angioedema, and rarely anaphylaxis (2) that develop 3-10 days before and subside 1-2 days after menses, with recurrent cyclic aggravation (1,3,4). Frequently, patients have a history of exogenous progesterone intake (1,5,6), as in our patient, which could have resulted in antibody formation. The diagnosis of APD is established by an appropriate clinical history (premenstrual flare of skin lesions), a progesterone intradermal test, an intramuscular (7), oral (8), or intravaginal (1, 6) progesterone challenge test, and circulating antibodies to progesterone. Progesterone testing has not been standardized. Most of the sex hormones are not suitable for testing since they contain an oily component that can produce an irritant test reaction. Gestodene, which was used for the oral provocation test in our patient, is a potent progesterone (9). The LTT shows reactions to circulating lymphocytes and reflects immune reactions within the body. The goal of treatment is suppression of ovulation. Currently, the first-line choice of therapy is a combination oral contraceptive (3). We believe that OCP have a limited effect because all of them contain a progesterone component. If this treatment is ineffective, patients have been treated with danazol, gonadotropin releasing hormone analogs (3,4,6), conjugated estrogens (7), tamoxifen, oophorectomy (8), and progestogen desensitization (10) with varying success.
