ABSTRACT
BACKGROUND: Although cystic fibrosis is the most common genetic disorder of children, its heterogeneous spectrum of severity lends itself to underdiagnosis in the older adult patient population where the index of suspicion is not high. METHODS: We report a 60-year-old Hispanic man with asthma who presented with progressive dyspnea and wheezing unresponsive to inhaled corticosteroid treatment. Additionally, he had clinical findings and a past history suggestive of cystic fibrosis. Skin testing, radiography and laboratory studies were completed to evaluate for allergic bronchopulmonary aspergillosis (ABPA) and cystic fibrosis. RESULTS: Test results revealed peripheral eosinophilia and hyper IgE. Skin testing to Aspergillus fumigatus (Af) was positive. IgG, IgM, and Af specific antibodies were present. High resolution CT scan showed central bronchiectasis. Sweat tests were positive on two separate occasions and gene analysis showed our patient to have a positive gene mutation at D127ON/D127ON. CONCLUSION: Cystic fibrosis should be suspected in the older adult patient with a compatible clinical presentation.

The significance and treatment of ventricular premature beats (VPBs) in patients without sustained ventricular tachycardia (VT), sudden death, or syncope remains unclear. We undertook a prospective study of programmed electrical stimulation (up to two extrastimuli and burst pacing) in 73 patients (age 60 +/- 10 years) with high-grade VPBs who had no evidence of sustained VT, sudden death, or syncope as determined by 48 hr of monitoring in the cardiac care unit and 48 hr Holter monitoring. Fifty-six patients (76.7%) had atherosclerotic heart disease, 10 (13.7%) had cardiomyopathy or valvular heart disease, and seven (9.6%) had no evident heart disease. Thirty-seven patients (50.7%) had Lown grade IVB VPBs, 30 (41.1%) had Lown grade IVA VPBs, and six (8.2%) had Lown grade III VPBs. Programmed electrical stimulation identified two groups of subjects: group 1 comprised 20 patients (27%) in whom VT or ventricular fibrillation was induced, group 2 comprised 53 patients (73%) in whom no ventricular arrhythmia or only two to four repetitive ventricular responses were induced. There was a significant difference between the presence of atherosclerotic heart disease, old myocardial infarction, and ejection fraction of less than 40% in group 1 compared with group 2. However, there was no significant difference in the grade of VPBs between the two groups. Seventeen of 20 patients from group 1 were placed on antiarrhythmic therapy (defined by programmed electrical stimulation), whereas group 2 patients were randomly assigned to prophylactic antiarrhythmic therapy. A total of 70 patients were followed up for 30 +/- 15 months. The incidence of sustained VT and/or sudden death (31.5% vs 2%; p less than .001) was significantly higher in group 1 compared with group 2.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of catheter-induced proximal dissection of an angiographically normal left coronary artery is reported. Dissection was not associated with pressure damping and myocardial ischemia was delayed until 1 hour after dissection occurred. Prompt recognition of this entity is essential as emergency revascularization is the treatment of choice when significant amounts of myocardium are threatened.

A patient with ring chromosome 13 had some physical and stigmata that to our knowledge have not been reported in previous articles. These include alopecia, scattered pigmentation, trigonocephaly, and telecanthic fold. This case reemphasizes how mitotic instability can produce clinical features during the critical period of organogenesis.
