Uncontrolled Blood Pressure in Hypertensive Patients with High Medication Adherence: A Korean Nationwide Population-Based Study / 가정의학회지

Background@#Uncontrolled blood pressure (BP) is relatively common despite treatment with antihypertensive medication. This study aimed to investigate factors associated with uncontrolled systolic BP (SBP) and diastolic BP (DBP) separately in hypertensive patients with high medication adherence in Korea. @*Methods@#This population-based cross-sectional study included 3,236 participants in the Korea National Health and Nutrition Examination Survey from 2013 to 2015. Hypertensive patients with high medication adherence were defined when they stated that they were taking antihypertensive medication daily. “Uncontrolled SBP and DBP” were defined as SBP ≥140 mm Hg and DBP ≥90 mm Hg, respectively. Data were analyzed using logistic regression to determine the association between uncontrolled SBP or DBP and various factors. @*Results@#The prevalence of uncontrolled SBP and uncontrolled DBP was 23.3%, and 9.0%, respectively. In multivariate analysis, uncontrolled SBP was positively associated with older age, female sex, blue-collar occupation or no work (vs. white-collar), presence of a spouse, short sleep duration, frequent heavy alcohol drinking, longer hypertension duration, diabetes, stroke, and missing antihypertensive medication on the examination day, but negatively associated with high stress. Uncontrolled DBP was positively associated with frequent heavy alcohol drinking, but negatively associated with older age, blue-collar occupation or no work (vs. white-collar), and diabetes. @*Conclusion@#After excluding low medication adherence, we identified various factors associated with uncontrolled SBP or DBP in Korean adults with treated hypertension. There were differences between factors associated with uncontrolled SBP or DBP. Separate analysis of SBP and DBP may help understand the factors involved in BP control.

Involuntary Flexor Spasms Associated with Basal Ganglia Infarction

Flexor spasm caused by stroke has been rarely reported. We describe a 79-year-old man who suddenly presented with flexor spasm of left limb and neck muscles. His symptoms consisted of recurrent episodes of brief paroxysmal flexor contractions of left limb and neck muscles without alteration of consciousness. Brain Magnetic Resonance Imaging revealed acute infarction in right basal ganglia. The abnormal movement was not associated with any epileptiform discharges in the video-electroencephalography monitoring. It was controlled with carbamazepine and phenytoin.

Two Series of Familial Cases With Unclassified Interstitial Pneumonia With Fibrosis

Several children presenting with mild symptoms of respiratory tract infection were diagnosed with unclassified interstitial pneumonia with fibrosis. Their clinical and radiological findings were similar to those of acute interstitial pneumonia, but there were some differences in the pathological findings. Unclassified interstitial pneumonia with fibrosis is characterized by histological findings of centrilobular distribution of alveolar damage and bronchiolar destruction with bronchiolar obliteration. This report describes two different series of familial cases of unclassified interstitial pneumonia with fibrosis, which developed almost simultaneously in the spring. Some of the individual cases showed rapidly progressive respiratory failure of unknown cause, with comparable clinical courses and similar radiological and pathological features, including lung fibrosis. Each family member was affected almost simultaneously in the spring, different kinds of viruses were detected in two patients, and all members were negative for bacterial infection, environmental and occupational agents, drugs, and radiation. These findings implicate a viral infection and/or processes related to a viral infection, such as an exaggerated or altered immune response, or an unknown inhaled environmental agent in the pathogenesis of unclassified interstitial pneumonia with fibrosis.
