Delivering Knowledge of Stroke to Parents Through Their Children Using a Manga for Stroke Education in Elementary School.

BACKGROUND: School-based intervention would be promising to spread stroke knowledge widely. This study aimed to clarify the effectiveness of our new educational aids that were developed for elementary school children to impart information about stroke to children and their parents in 2 different ways: with or without stroke lessons by a neurologist. METHODS: We enrolled 562 children (aged 11 to 12 years) and their parents (n = 485). The students were divided into 2 groups: 323 received a lesson on stroke by a stroke neurologist without watching an animated cartoon (Group I), and 239 watched an animated cartoon without the lesson (Group II). All of the children took the manga home, and talked about stroke with their parents. Questionnaires on stroke knowledge were administered at baseline (BL), immediately after the lesson (IL), and 3 months (3M) after the lesson. RESULTS: There were significant increases in the adjusted mean scores for risk factors as well as stroke symptoms at 3M in both groups compared with BL scores, although the children in Group I scored significantly better than those in Group II at IL and 3M (P < .05). In both children and parents, the correct answer rates of the FAST mnemonic at 3M were around 90%, with no significant differences between groups. CONCLUSIONS: Stroke education for elementary school children using our educational aids provided knowledge of stroke symptoms to the children as well as their parents even without lessons on stroke, although a better understanding of stroke was obtained from lessons led by stroke neurologists.

Frequency and Detection of Stanford Type A Aortic Dissection in Hyperacute Stroke Management.

BACKGROUND AND PURPOSE: Acute Stanford type A aortic dissection (AAD) is a devastating aortic disease, and prompt diagnosis is sometimes difficult to make. Identification of AAD in suspected acute stroke patients is especially challenging. Nevertheless, the frequencies and predictive factors of AAD in suspected acute stroke patients have not been well investigated. The aim of this study was to elucidate the prevalence of and predictors for AAD in patients with suspected acute stroke. METHODS: From January 2012 through January 2013, consecutive patients who visited our emergency department (ED) due to suspected acute (<24 h from onset) stroke were retrospectively enrolled. Clinical parameters including systolic blood pressure (SBP) and laboratory data were collected. Frequency of AAD in suspected acute stroke patients and acute ischemic stroke (AIS) subjects were assessed, and factors associated with AAD among AIS patients were investigated. RESULTS: A total of 1,637 patients were included in this study. Five patients (0.31%, 95% CI 0.04-0.57) were diagnosed as having AAD. The prevalence of AAD in all AIS individuals during the study period was 1.09% (95% CI 0.14-2.05), and AAD accounted for 1.70% (95% CI 0.05-3.36) of AIS patients who appeared at the hospital within 4 h from onset. Most AAD patients presented with disturbed consciousness, and none of the AAD patients complained of chest pain. Neck ultrasonography detected an intimal flap in AAD patients. Two AAD cases died soon after ED arrival. The remaining 3 were promptly diagnosed as having AAD in the ED and underwent emergency surgery; all were discharged with only mild neurological symptoms. Low SBP in the right arm (cut-off value ≤110 mm Hg, sensitivity 100%, specificity 94.4%) and high D-dimer level (cut-off value ≥5.0 µg/ml, sensitivity 100%, specificity 91.7%) had high predictive values for detecting AAD in patients with AIS presenting within 4 h from onset. CONCLUSIONS: AAD was seen in 0.31% of suspected acute stroke patients and 1.70% of AIS patients presenting within 4 h from onset. AAD patients who were initially suspected as having acute stroke had severe neurological symptoms, including disturbance of consciousness, did not complain of typical chest pain, and when emergency surgery was performed, favorable neurological and survival outcomes were achieved. Low SBP in the right arm and high D-dimer level could predict AAD.

Effects of stroke education of junior high school students on stroke knowledge of their parents: Tochigi project.

BACKGROUND AND PURPOSE: Educating the youth about stroke is a promising approach for spreading stroke knowledge. The aim of this study was to verify communication of stroke knowledge to parents by educating junior high school students about stroke. METHODS: We enrolled 1127 junior high school students (age, 13-15 years) and their parents in the Tochigi prefecture, Japan. All students received a stroke lesson, watched an animated cartoon, and read the related Manga comic as educational aids. The students took back home the Manga and discussed what they learned with their parents. Questionnaires on stroke knowledge were given to all at baseline and immediately after the lesson. RESULTS: A total of 1125 students and 915 parents answered the questionnaires. In the students, the frequency of correct answers increased significantly for all questions on stroke symptoms except for headache, and for all questions on risk factors after the lesson. In the parents, the correct answer rates increased for stroke symptoms except for headache and numbness in one side of the body, and for all questions on risk factors except for hypertension. Ninety-one percent of students and 92.7% of parents correctly understood the Face, Arm, Speech, and Time (FAST) mnemonic after the lesson. CONCLUSIONS: Improvement of stroke knowledge immediately after the stroke lesson was observed in parents as well as their children, which indicated that our teaching materials using the Manga was effective in delivering the stroke knowledge to parents through their children.

Effective Education Materials to Advance Stroke Awareness Without Teacher Participation in Junior High School Students.

BACKGROUND: Youth stroke education is promising for the spread of stroke awareness. The aim of this study was to examine whether our stroke awareness teaching materials without teacher's participation can increase student awareness to act fast on suspected stroke signs. METHODS: We used the face, arm, speech, and time (FAST) mnemonic derived from the Cincinnati Prehospital Stroke Scale. Seventy-three students of the second grade and 72 students of the third grade (age range, 13-15 years) in a junior high school were enrolled in the study. The students were divided into 2 groups: students who received a teacher's lesson (group I) and those who did not receive a teacher's lesson (group II). Students in group II watched an animated cartoon and read a Manga comic in class. All students took the educational aids home, including the Manga comic and magnetic posters printed with the FAST message. Questionnaires on stroke knowledge were examined at baseline and immediately and 3 months after receiving the intervention. RESULTS: At 3 months after the intervention, a significant improvement in understanding the FAST message was confirmed in both the groups (group I, 85%; group II, 94%). Significant increases in the knowledge of risk factors were not observed in each group. CONCLUSIONS: Our education materials include a Manga comic, an animated cartoon, and a magnetic poster, without an accompanying teacher's lesson can increase stroke awareness, including the FAST message, in junior high school students.

Carotid ultrasound features of anomalous left vertebral artery originating from the aortic arch proximal to the left subclavian artery.

We present three cases of anomalous origin of the left vertebral artery (LVA) detected during the evaluation of stroke. The VA usually enters the transverse foramen of the sixth cervical vertebra (C6), but an anomalous LVA originating from the aorta frequently enters at a higher level. In our series, ultrasound of the LVA showed entry at C4 in two patients and at C5 in one patient. These findings suggested anomalous LVA origin, and three-dimensional computed tomography demonstrated the LVA arising from the aorta proximal to the left subclavian arteries. Carotid duplex ultrasound is useful for the diagnosis of this anomaly.

Effects of school-based intervention by emergency medical technicians on students and their parents: a community-based prospective study of the Akashi project.

OBJECTIVE: Stroke lessons for youth provided by emergency medical technicians (EMTs) may be an effective strategy to facilitate early intervention for patients with stroke. The aim of this study was to examine how effective EMT-led lessons on stroke awareness for schoolchildren were at disseminating stroke information. SETTING, PARTICIPANTS AND OUTCOME MEASURES: The study was performed in the city of Akashi, Hyogo, Japan (Akashi project). Children (aged 9-10 years old) at 11 public elementary schools and their parents were enrolled in this study. EMTs from the firefighting headquarters provided lessons on stroke to the children using our educational materials between September 2014 and October 2015. Each child was given our educational materials to take home and discuss stroke with their parents. The children and their parents answered questionnaires on stroke knowledge before, immediately and at 3 months after the lesson. RESULTS: A total of 763 children and 489 parents were enrolled (ie, 64% of children). The scores of either stroke symptoms or risk factors were significantly higher immediately and at 3 months after the lesson, compared with before the lesson, both in children and the parents (p<0.01). Compared with the baseline in both groups (58% in children, 83% in parents), the meaning of the FAST mnemonic at 3 months (88%, 94%), as well as at immediately after the lesson (90%, 89%), was significantly higher (p<0.001). CONCLUSION: Stroke education by EMTs was effective in increasing stroke awareness in elementary school children, as well as their parents.
