Reversible cerebral vasoconstriction syndrome in the postpartum period: A case report and review of the literature.

Reversible cerebral vasoconstriction syndrome (RCVS) is a rare phenomenon that can present in the postpartum period. We show the experience of a 35-year-old patient who presented with headache after an uncomplicated pregnancy and vaginal delivery. She was initially diagnosed with pre-eclampsia, and subsequently with RCVS following discovery of multifocal vascular narrowing on magnetic resonance arteriography (MRA). Verapamil was initiated, and at 1 month there was improvement intracranially, but cervical vertebral arterial narrowing, likely dissection, was discovered. Verapamil was continued and aspirin was initiated. Follow-up imaging 5 months postpartum demonstrated near-complete resolution of previously noted abnormalities, which remained stable at reimaging at 10 months postpartum. In conclusion, the symptoms of RCVS can mimic or coexist with pre-eclampsia. Early intracranial imaging such as MRA can permit timely diagnosis and facilitate appropriate management and follow-up.

An Internet-Mediated Pedometer-Based Program Improves Health-Related Quality-of-Life Domains and Daily Step Counts in COPD: A Randomized Controlled Trial.

BACKGROUND: Low levels of physical activity (PA) are associated with poor outcomes in people with COPD. Interventions to increase PA could improve outcomes. METHODS: We tested the efficacy of a novel Internet-mediated, pedometer-based exercise intervention. Veterans with COPD (N = 239) were randomized in a 2:1 ratio to the (1) intervention group (Omron HJ-720 ITC pedometer and Internet-mediated program) or (2) wait-list control group (pedometer). The primary outcome was health-related quality of life (HRQL), assessed by the St. George's Respiratory Questionnaire (SGRQ), at 4 months. We examined the SGRQ total score (SGRQ-TS) and three domain scores: Symptoms, Activities, and Impact. The secondary outcome was daily step counts. Linear regression models assessed the effect of intervention on outcomes. RESULTS: Participants had a mean age of 67 ± 9 years, and 94% were men. There was no significant between-group difference in mean 4-month SGRQ-TS (2.3 units, P = .14). Nevertheless, a significantly greater proportion of intervention participants than control subjects had at least a 4-unit improvement in SGRQ-TS, the minimum clinically important difference (53% vs 39%, respectively, P = .05). For domain scores, the intervention group had a lower (reflecting better HRQL) mean than the control group by 4.6 units for Symptoms (P = .046) and by 3.3 units for Impact (P = .049). There was no significant difference in Activities score between the two groups. Compared with the control subjects, intervention participants walked 779 more steps per day at 4 months (P = .005). CONCLUSIONS: An Internet-mediated, pedometer-based walking program can improve domains of HRQL and daily step counts at 4 months in people with COPD.
