We analyzed the data on 15,438 consecutive medical inpatients monitored by the Boston Collaborative Drug Surveillance Program from June 1975 to June 1982 to determine the rates of allergic cutaneous reactions to drugs introduced since 1975 and to confirm and extend findings from an earlier study of the preceding 22,227 patients. There were 358 reactions occurring in 347 patients, for an overall reaction rate among patients of 2.2%. Each patient received a mean of eight different drugs. Rashes were attributed to 51 drugs, and 75% of the allergic cutaneous reactions were attributed to antibiotics, blood products, and inhaled mucolytics. Amoxicillin (51.4 reactions per 1000 patients exposed), trimethoprim-sulfamethoxazole (33.8/1000), and ampicillin (33.2/1000) had the highest reaction rates. Drug-specific reaction rates ranged from zero to 51.4 per 1000 and were determined for 180 drugs or drug groups. These results provide physicians with quantitative data that will be helpful in clinical decision making when drug-induced exanthems, urticaria, or generalized pruritus occurs.

Infantile seborrhoeic dermatitis is a dermatosis affecting infants characterized by little or no itching and by completely typical skin symptoms, distribution and evolution. Infantile seborrhoeic dermatitis should therefore be differentiated from atopic dermatitis and from diaper-rash although interferences be possible. In fact the high frequency of the atopic dermatitis and of diaper rash may cause these two manifestations to sometimes superimpose on infantile seborrhoeic dermatitis. This in turn causes rather complex clinical situations that may be very hard, but not impossible to diagnose if use is made of laboratory findings to support clinical features. The pathogenesis and etiology of infantile seborrhoeic dermatitis are still debated although recent results assign the dominant role to Candida albicans. This mycete also plays a relevant role in the genesis of diaper rash and particularly of Leiner's exfoliative erythrodermas, which can be interpreted as a generalized and erythrodermic expression of infantile seborrhoeic dermatitis. Systematic cultural investigations and appropriate antimycotic treatments, that would stimulate antibody response, will allow to clarify in the near future this interesting etiological problem, with important therapeutical consequences.

Healthy adult volunteers were inoculated intranasally with human parvovirus obtained from an asymptomatic blood donor. One week after inoculation, intense viremia was observed in seronegative volunteers, accompanied by a mild illness with pyrexia, malaise, myalgia, itching, and excretion of virus from the respiratory tract. In the following week hematologic studies revealed reticulocytopenia with an associated slight drop in hemoglobin concentration, lymphopenia, neutropenia, and a drop in platelet counts. At 17-18 days after inoculation a second-phase illness with rash and arthralgia lasting three to four days occurred in three of four infected volunteers. This study confirms the etiologic role of human parvovirus in erythematous rash illness, with the second-phase illness being consistent with adult cases of erythema infectiosum. Moreover, the hematologic changes associated with infection support the hypothesis that the same virus is responsible for the temporary arrest of erythropoiesis that leads to aplastic crisis in persons with chronic hemolytic anemia.

The therapeutic profile of enalapril in mild to moderate uncomplicated essential hypertension was assessed in 265 patients who participated in a multicenter, open-label, prospective study lasting eight weeks. There were 54 younger (aged 39 years or less), 136 middle-aged (40 to 59 years), and 75 older patients (60 years or over). Monotherapy with enalapril in a single daily dosage regimen ranging between 5 and 40 mg resulted in normotension (in the sitting position) in 73% of the younger, 50% of the middle-aged, and 56% of the older patients. Normotension was achieved with 5 mg/day of enalapril in 41%, 18%, and 37% of the subgroups, respectively. Both systolic and diastolic pressures at the end of eight weeks of treatment were significantly lower (P less than 0.01) in the younger patients than in the other two age groups. White patients had significantly greater (P less than 0.001) response of both systolic and diastolic blood pressures than did black patients and required significantly smaller (P less than 0.01) average daily dosages of enalapril (14 mg versus 22 mg, respectively). The overall incidence of side effects was 14% among all 276 patients enrolled in the study. Most were mild and transient, but six patients discontinued enalapril during the first week of therapy because of side effects. There were no cases of rash, dysgeusia, hematological disorders, or deterioration in renal function, but there were two cases of pruritus, one of glossitis associated with an upper respiratory infection, and three of dry cough or wheezing. Angioedema was not observed. Monotherapy with enalapril, usually in a single daily dose of 10 to 20 mg, was effective in inducing normotension in approximately half of the middle-aged and older hypertensive individuals and in nearly three fourths of those below age 40. In this study it was generally well tolerated, with a relatively small incidence of side effects.

Over the past 11 years (1974 to 1985) ten patients with perianal Paget's disease were treated. The average age was 64 years and half were male. Two patients were diagnosed as an incidental finding after hemorrhoidectomy and the remainder presented with a symptomatic perianal rash (itching and moisture) that averaged two years in duration. Physical examination in these patients demonstrated characteristic lesions (seven with erythematous or ulcerated, whitish gray lesions and one with a papillary lesion). Three patients presented with invasive carcinomas and, despite aggressive therapy, all developed metastatic disease. Two patients had local excisions with minimal margins and developed associated invasive cancers at four and ten years after diagnosis. The remaining five patients were treated by wide local excision and skin grafts. At present all are free of disease. The characteristic appearance of this lesion and its failure to respond quickly to conventional therapy should lead the clinician to obtain a biopsy which readily establishes the diagnosis. Experience confirms that wide local excision is adequate therapy, but adequate initial evaluation and close follow-up are necessary to identify other malignancies that may develop.

A 13-year-old boy who had had recurrent photosensitive skin reactions due to erythropoietic protoporphyria from 18 months of age, suddenly developed rapidly progressive hepatic failure with increasing cholestatic jaundice and variceal bleeding. Liver biopsy confirmed extensive protoporphyrin deposition with cirrhosis, and so orthotopic liver transplantation was performed. Postoperatively his skin rash settled within 72 hr, and in spite of subsequent exposure to the sun he has had no further skin reaction or blistering, although he does still have some itching. He made a good recovery and was able to return to school within six months of operation. Prior to liver transplantation, the hepatic ferrochelatase activity was reduced to only 0.81 nmol zinc-protoporphyrin formed/mg protein/hr (controls 3.30 +/- 1.00 nmol zinc-protoporphyrin formed/mg protein/hr, while the red cell protoporphyrin level was markedly elevated at 188 mumol/L red cells (normal less than 1.6 mumol/L red cells). The free plasma porphyrin level of 0.95 mumol/L (normal less than 0.02 mumol/L), and the urinary and fecal porphyrin levels were also raised. Following liver grafting these elevated porphyrin levels fell rapidly, with the red cell protoporphyrin level dropping to 10% of its preoperative value, and the rest returning to virtually normal within three months of operation.

Aztreonam (AZT) (2 g daily) was intravenously administered for 5 to 7 days to 65 patients with complicated urinary tract infections (UTI). Ninety one organisms were isolated from these patients' urine. Among them 66 organisms were eliminated following AZT administration. The elimination rate for Gram negative organisms was 94.7% and that for Gram positive organisms was 33.3%. Thirty one organisms appeared newly by the replacement of organisms. Among them, 12 organisms were E. faecalis. The efficacy rate of AZT in single infection and in mixed infection was 55.8% and 13.7%, respectively. The overall clinical efficacy rate of AZT in the present study was 41.5%. As side effects, skin rash and itching were observed in 3 patients and slight elevations in blood chemistry were observed in 10 patients. The results indicate that AZT is an effective drug for the treatment of patients with complicated UTI, especially those caused by Gram negative organisms.

Ceftriaxone (CTRX), an injectable cephem antibiotic agent, was studied for its pharmacokinetic properties and clinical usefulness in perinatal infections in obstetrics and gynecology on a multicenter basis. The study results are summarized below. 1. Following the one-shot intravenous injection of CTRX 1 g to pregnant women before labor, the maternal serum level of CTRX reached a peak at 131.8 micrograms/ml soon after the injection then it began to decrease gradually. T 1/2 was 6.7 hours. The umbilical serum level reached a peak at 16.0 micrograms/ml at 4.9 hours post-dose and decreased gradually with a half-life of 8.1 hours. The umbilical serum level was higher than the maternal serum level at about 12 hours post-dose. The amniotic fluid level reached a peak of 9.6 micrograms/ml at 12.8 hours post-dose. T 1/2 was 15.2 hours. The amniotic fluid level at about 15 hours post-dose or later exceeded the maternal serum level and was almost equal to the umbilical serum level at 24 hours post-dose. 2. Clinical usefulness was evaluated in 79 evaluable cases out of 89 treated for various infections at puerperium or for prophylaxis of infections at cesarean section or premature rupture of membranes (PROM). The efficacy rate was 100% in 7 cases of prenatal infections such as urinary tract infection and 30 cases of postnatal infections such as puerperal intrauterine infections. In 42 cases treated for prophylaxis in cases of cesarean section or PROM, the efficacy rate was 92.9%. Bacteriologically, 29 strains of pathogens were isolated from 26 cases. The disappearance rate of the pathogens was 96.0% as 23 strains were eradicated, 1 strain was substituted and no change was observed in 1 strain with unknown results in 4 strain. Skin rash and itching appeared in 1 patient as an adverse effect (1.1%). There were 10 cases of abnormal clinical laboratory test results such as elevated transaminase level were observed in 7 patients (7.9%). From the results, CTRX was considered to be a useful drug for the perinatal infection in the obstetrics and gynecology fields.

Forty-seven patients with chronic stable angina pectoris entered a thirteen-week open-label study with a transdermal therapeutic system of nitroglycerin in order to evaluate its clinical efficacy, safety, and patient acceptance. In 19 patients, a beta-blocker and in 17 patients a calcium-channel blocker were continued throughout the study period without alteration of their doses. The study consisted of a two-week run-in period and an eleven-week active drug period. Acute titration was done with nitroglycerin patches on the basis of weekly patient diaries on frequency of angina and sublingual nitroglycerin consumption. Overall, reductions in frequency of angina and in nitroglycerin consumption were statistically significant (p less than 0.05). Adverse reactions were common but tolerable. The reported side effects were headache in 32, skin rash in 18, dizziness in 10, palpitation and itching in 9 each, nausea in 7, flushing in 3, and vomiting in 1 patient. In conclusion, the present study demonstrates that individual dose titration with nitroglycerin patches for obtaining significant antianginal effect is essential. The present therapeutic system is convenient to use and well tolerated and had acceptable side effects in our study population.

In a 48-week, double-blind trial, 122 patients were randomly assigned to treatment with auranofin (60) and gold sodium thiomalate (GST) (62) at five centers. Both groups showed significant improvement (P less than 0.05) from baseline in parameters of disease activity. Results of the covariance analysis for all patients who completed the trial showed no significant differences (P less than 0.05) in efficacy between the two groups. The proportions of patients showing 50% or greater improvement in tender joints, swollen joints, activity index, severity of pain, general health rating, and erythrocyte sedimentation rate (ESR) were similar for both auranofin-treated and GST-treated patients who completed the 48-week trial. When all patients who entered the trial were evaluated, a slightly greater proportion of patients on auranofin had improved. Diarrhea occurred more frequently with auranofin (32%) compared to GST (19%), whereas rash and pruritus were twice as common in those patients treated with GST compared to those treated with auranofin. The withdrawal rate due to adverse reactions was 10% for auranofin vs 26% for GST. It was concluded that the efficacy of auranofin was comparable to that of injectable gold and was better tolerated, as evidenced by the lower withdrawal rate from adverse events for the auranofin patients.
