A peroral challenge test with 2--15 ml of propylene glycol (PG) was made in 38 patients with allergic-type epicutaneous test reactions to PG. Eight of 10 patients with a positive epicutaneous reaction to 2 % PG and seven of the other 28 patients with a positive epicutaneous reaction to 100-100 % PG developed an exanthem 3--16 h after ingestion of the drug. In all but one case the rash disappeared within 24--48 h without any medication. In one case the exanthem was treated with prednisone for 4 days, and the symptoms disappeared gradually in 6 days. None of the 20 control patients had skin symptoms. Nausea, vertigo and a curious sensation were recorded in four PG-sensitive patients and in three control patients. These symptoms were apparently due to the general pharmacodynamic effects of PG and they were regarded as non-allergic in nature. It was concluded that PG is a potential allergen and it must be added to the list of causes of drug exanthems.

Aim of the study was to assess the activity of dihydroergocristine (DHEC, CAS 17479-19-5) in aged patients with impaired cognitive function. Twenty-five university hospital centres and 250 physicians participated in the study. 2,600 patients (1,104 males and 1,496 females, age range 50-80 years) were admitted to the study. Each patient was administered 6 mg/d DHEC for 120 days. Clinical evaluation was made through the SCAG Rating Scale registered at basal time, after 60 and 120 days. Responsivity to treatment was considered high when the final score was reduced by 30% and none if less than 10%. Analysis of results demonstrated that at the end of the study responsivity was high in 73% of cases, moderate in 20.4% and absent in 6.5%. Tolerability was very good as side effects were reported only in 3.16% of patients. Most frequent side effects were: nausea (1.23%), gastralgia (1.11%), headache (0.29%), hypotension (0.12%), vertigo (0.12%) and rash (0.08%). Drop-outs for gastralgia were reported only in 0.53% of the patients.

A total of 555 hypertensive patients took part in a 2-year multicenter, open-label study to determine the efficacy, tolerance, and safety of long-term therapy with ramipril. In the beginning, all patients were to receive 5 mg of ramipril/day. The dosage was then adjusted in accordance with response to treatment and ranged from 1.25-20 mg of ramipril daily. Of these patients, 129 also received 25 mg of hydrochlorothiazide daily at some point during the trial. To evaluate whether tolerance to ramipril developed during long-term treatment, a subgroup of 202 patients was analyzed for efficacy maintenance. Prior to enrolling in the 2-year study, these patients had received ramipril monotherapy in a short-term, double-blind study and had been classified as responders, i.e., their diastolic blood pressure had been maintained at less than or equal to 90 mm Hg. At the end of 104 weeks of treatment, 45.9% of patients were on 2.5 mg of ramipril alone and 43.6% were on 5 mg of ramipril alone. Only four patients required the addition of 25 mg of hydrochlorothiazide. No clinically important changes occurred, and kidney function was well maintained. The most frequently reported adverse events excluding intercurrent illnesses were dizziness/vertigo (6%), asthenia (4%), nausea (3%), headache (2%), and abdominal pain, gastrointestinal disorder, rash, and increased cough (1% each). Ramipril was safe, effective, and well tolerated in the long-term treatment of patients with mild-to-moderate essential hypertension.

A 48 year old male patient presented with maculopapular rash, pruritus, peptic ulcer disease and attacks of headache and vertigo. Rubbing of the cutaneous lesions led to urticarial whealing which is indicative of abnormal mast cell proliferation in the cutis. Histologic evidence of abnormal mast cell proliferation in biopsy specimens of skin and bone marrow led to the diagnosis of systemic mastocytosis. Treatment with H1 and H2 receptor antagonists was started.

Lyme disease is a systemic illness caused by the spirochete Borrelia burgdorferi and transmitted by the bite of a tick in the Ixodes ricinus complex. While the illness is often associated with a characteristic rash, erythema migrans, patients may also present with a variety of complaints in the absence of the rash. The otolaryngologist may be called upon to see both groups of patients, with any number of signs and symptoms referable to the head and neck, including headache, neck pain, odynophagia, cranial nerve palsy, head and neck dysesthesia, otalgia, tinnitus, hearing loss, vertigo, temporomandibular pain, lymphadenopathy, and dysgeusia. We review our institutional experience with 266 patients with Lyme disease, 75% of whom experienced head and neck symptoms. We also summarize the diagnostic and treatment modalities for this illness.

Converting enzyme inhibitors (CEIs) are widely used in treatment of essential hypertension. Large-scale clinical studies have shown that CEIs are well tolerated and cause fewer side effects than most other antihypertensive agents. The latter observation is fundamental for compliance with long-term treatment. There do exist, however, some side effects which although rare are not negligible. It is necessary though to distinguish between side effects linked to the class of therapeutic agents and those associated with particular structural features. Three types of side effects have been seen: 1) manifestations linked to inhibition of angiotensin II with systemic vasodilation (hypotension, vertigo) and decreased glomerular pressure (functional renal impairment) with preferred onset in renovascular hypertension; 2) potentiation of the bradykinin-prostaglandin system which causes cutaneous eruptions and for reasons still poorly understood a cough which may justify discontinuance of treatment: 3) side effects for which the sulfydryl group is essentially responsible (rash, dysgeusia, neutropenia, proteinuria) and which basically appear to be linked to the use of high doses of captopril. In general terms, and bearing in mind the frequently dose-dependent character of the side effects, it is advisable to prescribe low doses of CEIs, and this therapeutic approach is strengthened by the possibility of concomitant use of a thiazide diuretic allowing improved antihypertensive effects, coupled to better reciprocal tolerance of the drugs. The end result is a better quality of life for the hypertensive subject, and hence improved compliance with long-term treatment.

Ramsay Hunt syndrome is known to cause audiological signs and symptoms, including sudden, unexpected hearing loss. We carried out a retrospective review of the audiological manifestations of 186 patients with Ramsay Hunt syndrome, measuring their hearing loss patterns, hyperacusis, tinnitus, herpetic rash, facial paralysis, pain and vertigo. Statistical correlations of these parameters were equated with prognosis. Prognosis for eventual hearing recovery is, in general, excellent. Prognostic indicators of poor hearing recovery include advanced age, retrocochlear hearing loss, male gender, vertigo, and speech frequency hearing loss.

To evaluate the value of the nonsedative anticonvulsants carbamazepine and valproic acid a controlled study including drug monitoring was carried out. Intoxicated alcoholics (n = 138) were admitted for inpatient detoxication and randomly assigned to either carbamazepine (n = 43), sodium valproate (n = 46) or placebo (n = 49) in a double-blind fashion. Drug treatment lasted for four days and the daily doses of both drugs amounted to 1200 mg in the beginning of the study. Sodium valproate induced gastric distress, nausea and vomiting more frequently than placebo. About half of the subjects had to stop carbamazepine because of intolerable side-effects including vertigo, nausea, vomiting, diplopia and rash. Serum carbamazepine levels (18-89 mumol/l) were found to be high (greater than 40 mumol/l) in many but not all of these subjects. Seizures occurred in 3 subjects on placebo, 2 on carbamazepine and 1 on sodium valproate. Delirium tremens developed in 2 on sodium valproate and 1 on placebo. The study demonstrates that drug side-effects may seriously hamper the utility of carbamazepine and sodium valproate as routine treatment for the prevention of alcohol withdrawal symptoms.

A rare case of systemic lupus erythematosus (SLE) associated with lateral medullary syndrome and unilateral internuclear ophthalmoplegia was reported. A 15 year old girl was admitted to Kyushu University hospital on 2 September in 1987 because of vertigo, occular symptom, and sensory disturbance. She had noted vertigo since 28 August. On admission she had nystagmus, left Horner syndrome, sensory disturbance of left hemiface and right limbs and trunk and mild hemiparesis of right limbs. She also had a discoid erythema behind the left ear, butterfly rash on her cheek. She developed right internuclear ophthalmoplegia on 6 September. Investigations revealed biological false positive of serological test for syphilis, positive antinuclear antibodies, and prolonged APTT. Peripheral blood cell count and erythrocyte sedimentation rate were normal. There was no proteinuria. Computed tomography and magnetic resonance imaging failed to detect any lesions in the brain. Cerebrospinal fluid cell count was 20/3 and Ig-G index was 17.1%. Her neurological signs were thought to be related to SLE. Lupus anticoagulant might be responsible for the development of impairment of central nervous system (CNS). She was treated with prednisolone, initial dose of 40mg, and the symptoms and signs were improved quickly. Early diagnosis and treatment for SLE with CNS involvement is primarily important.

A 22-year-old familial Mediterranean fever (FMF) patient was hospitalized for continuous fever, myalgia, hypertension, vertigo and a petechial rash. Laboratory findings revealed hyperglobulinaemia, thrombocytosis and a leukaemoid reaction. While on steroid therapy the patient sustained a haemorrhage into a renal aneurysm which responded to gel foam embolization. After 12 months of follow-up his condition remained stable under treatment with cyclophosphamide, prednisone and antihypertensive medications. This case provides the fourth example of polyarteritis nodosa associated with FMF.
