Pilot Study of 15 Patients Receiving a New Treatment Regimen for Androgenic Alopecia: The Effects of Atopy on AGA.

Background. We examined the efficacy of a new regimen to treat AGA, with attention to male patients who are atopic. Objective. To assess the efficacy of a four-part regimen for the treatment of AGA in atopic and nonatopic patients. NuH Hair is a novel topical combination of finasteride, dutasteride, and minoxidil, which is blended in a hypoallergenic lotion. The other three components included Rogaine foam, Propecia, and ketoconazole shampoo. Methods. A prospective pilot study was conducted in 15 patients. All patients were assessed for the presence of atopy. Each patient served as their own control. All patients were treated specifically with NuH Hair and were given the option to add any of the other components of the protocol to their regimen. Photographs were taken of each patient's scalp at months 0, 1, 3, 6, and 9. Results. All 15 patients demonstrated significant growth of hair. In those patients who utilized all 4 components, significant growth was achieved in as little as 30 days. In those patients who choose only to utilize NuH Hair, significant growth was demonstrated after 3 months. Conclusion. Aggressively treating AGA achieves significant and rapid growth of new hair. This is effective in atopic and nonatopic male patients.

Comparison of the bronchodilatory effects of cetirizine, albuterol, and both together versus placebo in patients with mild-to-moderate asthma.

BACKGROUND: Many potential users of the H1 antihistamine cetirizine are asthmatic and may be using inhaled albuterol. This study was conducted to assess the possible bronchodilatory effect of cetirizine in patients with mild-to-moderate asthma and to determine whether cetirizine interacts with albuterol. METHODS: In a randomized, double-blind, placebo-controlled, crossover study, the effects on pulmonary function of 5, 10, and 20 mg oral doses of cetirizine with and without inhaled albuterol (180 micrograms) were determined in 12 patients at 11 time points over 8 hours. The primary measure of efficacy was forced expiratory volume in 1 second (FEV1). RESULTS: Cetirizine with or without albuterol significantly increased FEV1, peak expiratory flow rate, and forced expiratory flow rate between 25% and 75% of vital capacity relative to baseline and placebo but did not have a significant effect on forced vital capacity. The effect of 20 mg of cetirizine on FEV1 was generally greater than that of 10 or 5 mg, but the difference was statistically significant only at the 30-minute time point (p < 0.05). All three cetirizine doses produced significantly greater increases than placebo in FEV1 and forced expiratory flow rate between 25% and 75% of vital capacity for 8 hours and in peak expiratory flow rate for 7 hours (p < 0.02). Albuterol alone had a significant effect on the four pulmonary function variables from 1 to 5 hours after baseline (p < 0.05), which is consistent with albuterol's recommended dosing frequency of every 4 to 6 hours. Albuterol alone increased FEV1 significantly more than 5 mg of cetirizine alone but not 10 mg or 20 mg of cetirizine alone at 60, 90, and 120 minutes after baseline, but all three doses of cetirizine increased FEV1 significantly more than albuterol 7 and 8 hours after baseline (p < 0.05), indicating that the bronchodilatory action of cetirizine lasts longer than that of albuterol. Cetirizine neither potentiated nor inhibited the bronchodilatory action of albuterol, but the two drugs appeared to have an additive bronchodilatory effect. None of the cetirizine treatments caused a worsening of pulmonary function, and all were well tolerated. CONCLUSIONS: Cetirizine has a significant bronchodilatory effect in patients with mild-to-moderate asthma and can be used to treat concomitant conditions (e.g., allergic rhinitis) without concern that it will interfere with the bronchodilatory effect of albuterol or cause worsening of asthma by itself.

A comparison of imaging techniques in patients with chronic sinusitis (X-ray, MRI, A-mode ultrasound).

Thirty-five patients age 9 to 67 were evaluated for chronic sinusitis by history, physical and laboratory examination, and imaging techniques (X-ray, magnetic resonance imaging (MRI) and flexible rhinoscopy). MRI was the most predictive. To establish the diagnosis of sinusitis, it was more sensitive than plain X-ray for intrasinus disease. Findings of edema, erythema, and drainage on flexible rhinoscopy were consistent with chronic sinusitis and were confirmed by MRI and sinus X-rays in 41% of the cases. Nasal smears for polymorphonuclear cells and eosinophils were suggestive of a diagnosis of chronic sinusitis, but other laboratory tests (CBC, sedimentation rate, quantitative immunoglobulins, total IgEs) were of very limited value in the diagnosis of chronic sinusitis.

Economic assessment of ketorolac versus narcotic analgesics in postoperative pain management.

The medical records for 174 patients who underwent cholecystectomy (n = 52) or hip/knee replacement (n = 122) at four community-based medical centers were retrospectively reviewed to determine if using a nonnarcotic alternative to morphine sulfate and/or meperidine as a primary postoperative analgesic could reduce resource costs per patient. Two cohorts were constructed: 87 patients received either morphine sulfate or meperidine as the primary postoperative analgesic, and 87 patients received ketorolac. Ketorolac patients undergoing cholecystectomy were associated with lower per case costs in inpatient care (length of stay), direct nursing labor, PRN (as required) procedures, and medications relating to emesis and to gastrointestinal distress. Higher per case costs were recorded for the primary analgesic (study drug) and for supplemental pain medications. In contrast to substantial differences in the acquisition cost of ketorolac versus morphine sulfate/meperidine, the ketorolac cholecystectomy group was associated with lower overall resource costs per patient. In joint replacement procedures, however, the ketorolac group was associated with higher overall resource costs per patient, attributable primarily to a slightly higher postoperative length of stay.

Effect of terfenadine in asthmatic patients.

The bronchodilator effect of terfenadine, 60-mg or 120-mg single dose, and 1 week twice daily dosing, was evaluated in 12 allergic asthmatic patients. When compared with baseline, FEV1 rose significantly for single dose 120 mg terfenadine at one, one and one-half, three, five and one-half, and six hours and for 60 mg terfenadine at three, five and one-half, six, and eight hours postdose. Variations in patient response were observed. At steady state, 120 mg terfenadine b.i.d. showed consistent improvement over placebo from three to 12 hours postdosing but no improvement in FEV1 was noted for terfenadine, 60 mg b.i.d. There no longer was a statistically significant difference in mean FEV1 or percent change from baseline. Thus, terfenadine proved to be a safe and a mild bronchodilator; however, tachyphylaxis might develop to the bronchodilator effect after 1 week of continuous b.i.d. dosing.

Pediatric airway manifestations of gastroesophageal reflux.

Gastroesophageal reflux (GER) in children may be classified as physiologic or pathologic, depending on its degree and consequences. There are many head and neck complications of GER in pediatric patients, but most numerous are the airway manifestations, including stridor, recurrent croup, exacerbation of subglottic stenosis, laryngeal irritation with or without laryngospasm, chronic cough, and obstructive apnea. Diagnosis may be difficult unless there is a high index of suspicion for GER and awareness of the concept of "silent" GER. We present the common pediatric airway manifestations of GER, illustrated by case reports, and provide a paradigm to assist in the diagnosis and management of children with airway compromise associated with GER.

Compliance in clinical trials of two nonbronchodilator, antiasthma medications.

An electronic monitoring device was used to assess patient compliance during clinical trials of two new aerosolized nonbronchodilator, antiasthma drugs. Compliance was poor, but similar, in both trials. Patients took the study drug as instructed on a mean of 37.3% days (range 10% to 77%) in one trial and 37.4% days (range 0% to 63%) in the other. Both underuse and overuse were observed. Underuse was seen on a mean of 38.9% days (range 9% to 81%) and 46.0% (range 15% to 80%) respectively; overuse on a mean of 23.5% days (range 6% to 54%) and 16.6% days (range 0% to 41%). In some patients ten or more activations of the device were recorded at the same time. In six patients such multiple simultaneous activations were recorded on two or more separate days. These patients were among the most noncompliant in the study. Multiple simultaneous activations frequently followed underuse days or preceded followup visits, suggesting the possibility of duplicity. Overall compliance was such that valid conclusions about efficacy of the drugs could only have been drawn in six of 34 patients.

The microbiology of chronic sinus disease in children with respiratory allergy.

Chronic maxillary sinusitis is common in children with respiratory allergy and is associated with increased morbidity. The bacteriology of chronic sinus disease in these children has not been adequately evaluated. Between May 1987 and January 1988, 12 children (aged 3 to 9 years), all with documented respiratory allergy and chronic respiratory symptoms consistent with chronic sinusitis (greater than 30 days), were fully evaluated. History, physical examination, complete blood count, nasal smear, and Waters x-ray were done. All patients had opacification of one or both maxillary sinuses, failed to respond to multiple courses of antibiotics, and subsequently underwent maxillary sinus aspiration and irrigation. Specimens were cultured for aerobic and anaerobic organisms with standard technique, and sensitivities were obtained. Culture results revealed a single organism (Moraxella [Branhamella] catarrhalis) in five patients, one patient yielded M. catarrhalis plus Streptococcus species, three were negative, and three patients grew multiple organisms (two with multiple aerobic streptococcal species and one patient with aerobic streptococci and Peptostreptococcus). All children received appropriate culture-directed antimicrobial therapy. Sequential biweekly follow-up revealed progressive radiographic clearing and significant symptomatic improvement. M. catarrhalis is a common pathogen, whereas anaerobic organisms are unusual as a cause of chronic maxillary sinusitis in allergic children. Some children, despite negative cultures, may benefit from maxillary sinus irrigation.

The natural history and response to therapy of chronic urticaria and angioedema.

Previous reports have suggested that the etiology of chronic urticaria/angioedema (greater than 6 weeks) can be identified 10% to 30% of the time while few reports have addressed the natural history of chronic urticaria/angioedema. An analysis of all patients referred to the authors' practice between 1983-1985 with a diagnosis of urticaria/angioedema was performed. Patients with hereditary angioedema were excluded. Eighty-six of the 214 patients had chronic urticaria/angioedema. In the remaining 128 cases of acute urticaria there were four exercise induced, nine contact, six cold induced, six drug induced, 11 food induced, one viral hepatitis associated, 29 with dermographism, and 62 undetermined. An etiology could not be determined in any of the patients with chronic urticaria/angioedema. Laboratory tests, including CBC, chemistry panel, urinalysis, ANA, rheumatoid factor, complement studies, sedimentation rate, and skin tests were all noninformative. Chronic angioedema without urticaria occurred in only nine cases, 31 cases had chronic urticaria alone, and 46 cases had both chronic urticaria and angioedema. Of the patients followed over the 3-year period, 27 resolved while 48 continued to have urticaria/angioedema. Response to medications was variable and will be discussed. Our study suggests that an etiology is determined in much less than 10% of patients with chronic urticaria; fortunately, 32% of our cases resolved over a 3-year period.

Exercise-induced asthma/other allergic reactions in the athlete.

Many US athletes with exercise-induced asthma (EIA) and allergies won medals in the 1984 Olympics, proving that EIA need not sideline an athlete. This article reviews EIA and the pathophysiology of the condition as well as other allergic reactions. The development of EIA is influenced by the type and duration of exercise and by air contaminants. Air temperature and humidity have been recognized recently as more important factors. Exercising in a warm, humid environment and breathing slowly through the nose help to control EIA. Four groups of drugs that are safe and effective against EIA are discussed. Other allergic reactions include the upper respiratory tract, i.e., nose and sinuses as well as skin reaction to environmental exercises.

Chronic sinusitis in the allergic child.

Chronic inflammation of the paranasal sinuses, especially the maxillary sinuses, is common in children with respiratory allergy. The presence of sinusitis should be suspected in such children when they have chronic night and early morning cough or poorly controlled asthma. Treatment should be aggressive because morbidity can be high.
