Skin test results and self-reported symptom severity in allergic rhinitis: the role of psychological factors

BACKGROUND: In allergic conditions, the degree of skin test reactivity does not always correlate with the severity of clinical symptoms. Additional factors may contribute to the reported symptom severity. OBJECTIVES: To investigate the association between the magnitude of the skin prick test (SPT) response and the reported symptom severity in patients with allergic rhinitis and the possible modifying role of psychological factors. METHODS: One hundred four patients with allergic rhinitis and 23 with non-allergic rhinitis, classified according to their SPT response to 19 aeroallergens, were asked to rate the severity of five symptoms and to indicate whether their symptoms intensified on exposure to five common aeroallergens. They also completed a psychological questionnaire. Results Reported symptom severity of allergic rhinitis did not correlate with weal size for any of the aeroallergens tested or with the number of positive responses on SPT. It was not related to patient age, sex, or education. The reported symptoms severity correlated positively (0.29, P < 0.01) with reported symptom intensification on exposure to allergens. Moreover, both outcomes were positively associated with the psychological factors of hypochondriasis (0.20, P < 0.05 and 0.18, P < 0.05, respectively), and somatic awareness (0.24, P < 0.05 and 0.33, P < 0.01, respectively), but not with neuroticism. CONCLUSIONS: The severity of symptoms experienced by patients with allergic rhinitis is apparently not related to the magnitude of SPT response, but rather to psychological factors of hypochondriasis and somatic awareness. Physicians should be aware of the contribution of psychological factors to patient perceptions of the intensity of symptoms and of the intensification of symptoms on their exposure to allergens.     

Charting the use of electronic health records and other information technologies among child health providers

Background  

Previous studies regarding the use of information technologies (IT) specifically among pediatricians and other physicians who treat children are lacking. As such, the objective of this study is to examine the use of electronic health record (EHR) systems and other IT applications among pediatricians and other child health providers (CHPs) in Florida.     

Right upper lobe 'window' in right main bronchus stenting.

Stent insertion for bronchial stenosis has become common practice in lung transplantation and advanced lung malignancy, and for external compression of the airways for other reasons. Right main bronchus stenting may require blocking the right upper lobe by the stent, placing the patient at risk of recurrent pneumonia and atelectasis. In this study, three patients after insertion of a metal stent to the right main bronchus are described. In all cases, the right upper lobe was covered by the stent, and a laser (Nd:YAG) procedure was used to open a 'window' in the stent toward the right upper lobe with a follow-up of 1 year. We conclude that stent insertion to the right main bronchus may be followed by a laser therapy to open a 'window' toward the right upper lobe.     

Retinal detachment adherent to posterior chamber IOL after Molteno implant surgery

A patient with refractory glaucoma 1 year after cataract extraction and trabeculectomy had Molteno implant surgery. Three days after surgery a kissing choroidal effusion and retinal detachment adherent to the posterior chamber IOL were detected. Repeated choroidal taps were unsuccessful. Removal of the Molteno implant, vitrectomy, and silicone oil injection were required to reattach the retina.     

Executive cognitive deficits in primary dystonia.

Primary dystonia is a disorder of movement for which no consistent pathophysiology has been identified; in the absence of evidence to the contrary, it is assumed to be cognitively benign. We have studied a clinically heterogeneous group of 14 patients with primary dystonia on a battery of neuropsychological tests. Despite well-preserved speed of information processing, language, spatial, memory and general intellectual skills relative to normal controls, we have identified a constellation of attentional-executive cognitive deficits on the Cambridge Neuropsychological Test Automated Battery (CANTAB). Specifically, patients demonstrated significant difficulties negotiating the extra-dimensional set-shifting phase of the IED task. The implications of these findings for the pathophysiology of primary dystonia are discussed. This is, to the best of our knowledge, the first report of a significant cognitive deficit in patients with primary dystonia.     

Progressive multifocal leukoencephalopathy in a lung transplant recipient.

Progressive multifocal leukoencephalopathy (PML) is a sub-acute, demyelinating disease of the brain caused by a human polyomavirus. We describe a patient with the onset of PML 7 months after lung transplantation. The patient was treated with immunosuppressive modulation and cidofovir, a new anti-viral therapy for PML, with stabilization of the symptoms. We also review the 4 additional reports in the literature of PML after heart and lung transplantation. Progressive multifocal leukoencephalopathy may become more prevalent as the population of heart and lung transplantation recipients increases.
