BACKGROUND

Blood pressure (BP) is a vital sign that is essential in the management of hypertension, thus, there is a need for accurate measurement of BP. This will allow for proper diagnosis and management of hypertension preventing cardiovascular morbidity and mortality among Filipino patients.

METHODOLOGY

This validation study utilized the US Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) protocol for BP monitors. A total of eighty-five (85) participants had their BP measured using both the HEM 7156 and a validated aneroid sphygmomanometer. The same-sequential BP measurement was recommended to be used and a total of nine readings were collected per individual. The mean average of BP and standard deviation were extracted from the measurements. The AAMI/ESH/ISO recommends the use of certain criteria for individual BP readings (criterion 1) and individual participants (criterion 2). Appropriate statistical analysis was used for other demographic data.

RESULTS

The participants had an average age of 34 years, more than half were females, and not diagnosed with hypertension. Individuals who were diagnosed with hypertension had no other comorbidities and were on single pill only. The average arm circumference was 26.9 cm. Blood Pressure (BP) readings were adequate based on the protocol. Validity results showed that for criterion 1, systolic blood pressure (SBP) difference was 3.4 ± 7.4 mmHg, while diastolic blood pressure (DBP) was 2.0 ± 8.0 mmHg. The results for criterion 2 showed for SBP was 3.3 ± 5.3 mmHg, while DBP was 1.9 ± 6.6 mmHg. The results satisfied a passing grade on the validation protocol set by the AAMI/ESH/ISO.

CONCLUSION

This study showed that OMRON HEM 7156 is validated as a BP apparatus and may be recommended for Philippine use.

Introduction: In the Philippines, essential eye care services are not easily accessible especially for those in lower income groups, putting public elementary school students at risk for underdiagnosis of problems in visual acuity. The objective of this investigation was to determine prevalence of undetected refractive errors among public elementary students using the Welch Allyn Spot™ Vision Screener. Methods : A cross-sectional design was used in this investigation to estimate the prevalence of uncorrected refractive errors in the first grade students in San Perfecto Elementary School using Welch Allyn Spot™ Vision Screener (Photoscreener). Eligible students who gave informed consent and assent answered a questionnaire and underwent an eye examination. The prevalence of undetected errors of refraction were computed for the sample population and for selected demographic variables. Results : Approximately one out of four students (24.53%) had errors of refraction, with the most common type being astigmatism (22.64%), followed by myopia (3.77%) and hyperopia (2.83%). Conclusion This study revealed a high prevalence of undetected refractive errors among school-age children, higher than current published data (5%) in the Philippines.

BACKGROUND: Medial medullary infarction is a rare entity of cerebrovascular events and the bilateral involvement of the medial medulla is much more infrequent. The characteristic presentations of a medical medullary infarction are the presence of contralateral hemiplegia sparing the face, contralateral sensory loss and ipsilateral hypoglossal paralysis while the presence of quadriparesis is the hallmark of the bilateral medical medulla infarction. Atherosclerosis of the vertebral artery is the most common stroke mechanism.

CASE: We present a case of a Filipino who presented with quadriplegia and was diagnosed with bilateral medial medullary infarction and was demonstrated by magnetic resonance imaging. Likewise, we reviewed the literature of the reported cases of bilateral medial medullary infarction.
