Telangiectasia and Pulmonary Arterial Hypertension Following Treatment With Trastuzumab Emtansine: A Case Report.
Trastuzumab emtansine (T-DM1) is a Food and Drug Administration-approved novel agent for the treatment of HER-2 positive advanced breast cancer. We report a case of pulmonary arterial hypertension (PAH) that we attribute to the use of T-DM1. A 43-year-old woman with stage IV breast cancer presented with dyspnea on exertion. ⋯ History revealed that the patient had been on T-DM1 before presentation. During T-DM1 treatment, the patient experienced hereditary hemorrhagic telangiectasia-like symptoms consisting of spider angiomata-skin lesions, epistaxis, and hematochezia, which resolved with discontinuation of T-DM1. Temporal associations of T-DM1 use with the development of PAH in the patient, and the reported association between hereditary hemorrhagic telangiectasia and PAH via genetic linkage, led us to suspect T-DM1 as the cause of PAH.

Reducing hospital readmissions has attracted attention from many stakeholders. However, the characteristics of 30-day readmissions after asthma-related hospital admissions in adults are not known. It is also unclear whether older adults are at higher risk of 30-day readmission. ⋯ After asthma-related admission, 14.5% of patients had 30-day readmission with wide range of principal diagnoses. Compared with younger adults, older adults had higher 30-day readmission rates and proportions of nonrespiratory diagnoses.

Observational Study
Impact of Adenotonsillectomy On Insulin Resistance And Lipoprotein Profile In Nonobese And Obese Children.
OSA associates with insulin resistance (IR), hyperglycemia, and dyslipidemia consistently in adults, but inconsistently in children. We set out to quantify the impact of OSA treatment upon obesity and metabolic outcomes and thus assess causality. ⋯ T&A improved IR and HDL, and residual OSA is predicted by baseline FPI and BMI z score, indicating a causal relationship; however, following T&A, residual metabolic dysfunction related to underlying adiposity rather than remaining sleep-disordered breathing. Finally, T&A cured OSA in < 25% of all children and only 10% of obese children; post-T&A polysomnography is indicated to assess which children still require treatment.

Younger persons with COPD report worse health-related quality of life (HRQL) than do older individuals. The factors explaining these differences remain unclear. The objective of this article was to explore factors associated with age-related differences in HRQL in COPD. ⋯ Age-related differences in HRQL may be explained by a higher impact of dyspnea among younger subjects with COPD.
