Review
After a little more than a century of use, the conventional Riva-Rocci/Korotkoff technique of measuring blood pressure with a mercury sphygmomanometer and stethoscope, is now being relegated to the museum shelves. Affectionately attached though we may be to this clinical measurement, we must acknowledge that the technique is fraught with inaccuracy and that the age of technology has brought more accurate alternative methodologies. However, we must ensure that the automated devices that are replacing the conventional technique are validated independently for accuracy. The Working Group on Blood Pressure Monitoring of the European Society of Hypertension has recently published an International Protocol to facilitate the validation of more automated devices than was possible with the earlier more complicated protocols.

Suicide by asphyxia is quite a common event in forensic practice and may be implemented in different ways. The authors report a unique case of a 16-year-old youth who committed suicide by means of a standard mercury sphygmomanometer. This manner of suicide has never been described in the literature reviewed. A complete forensic investigation led to the conclusion that the cause of death was mechanical asphyxia, ascribed to self-strangulation by means of an atypical item. The victim suffered from attention-deficit/hyperactivity disorder (ADHD) syndrome and was assisted by support teachers. He had a solitary and depressive personality. The exceptional nature of this case suggests that sphygmomanometers may be regarded as possible means of self-strangulation. The case also highlights the importance of managing patients with psychiatric or cognitive disorders; indeed, particular caution is required to keep them away from objects that, although apparently harmless, can become lethal.

Observational Study
OBJECTIVES
Objectively measuring pain sensitivity has not been easy in primary care clinics. A sphygmomanometer test (a sensory test that measures an individual's nociceptive response to pressure using a standard blood pressure cuff) has recently been established to test pain sensitivity. Here, we examined the feasibility of using the sphygmomanometer test with chronic pain patients.
DESIGN
Population, observational study.
SETTINGS
A community hospital multidisciplinary Pain Center and a private nonprofit university.
SUBJECTS
Healthy controls and chronic pain patients were recruited.
METHODS
All subjects underwent four pain sensitivity tests: a pressure algometer test, a cold pressure test, a heat sensitivity test, and a sphygmomanometer test. Participants then completed four established surveys for evaluating depression (Patient Health Questionnaire-9), anxiety (General Anxiety Disorder-7), fatigue (Fatigue Severity Scale), and pain catastrophizing (Pain Catastrophizing Scale).
RESULTS
Although pain patients had significantly higher levels of depression, anxiety, fatigue, and pain catastrophizing, as well as reported pain scores, no significant differences in pain sensitivity were detected via any of the pain sensitivity tests. In the control but not the patient group, results from all pain sensitivity tests including the sphygmomanometer test were significantly correlated with each other. Unlike other pain sensitivity tests, the sphygmomanometer test did not correlate with measures of depression, anxiety, fatigue, or pain catastrophizing characteristics.
CONCLUSIONS
Our results indicate the unique characteristics of the sphygmomanometer test as a pain sensitivity test, particularly when utilized for individuals with chronic pain. Multiple pain sensitivity tests that assess various sensory modalities are needed to evaluate pain sensitivities in chronic pain patients.

BACKGROUND
Using manometer sphygmomanometers as standard measurement tool, there are controversial data regarding accuracy and validity of digital manometers for measurement of systolic (SBP) and diastolic blood pressure (DBP). Thus, we aimed to compare the accuracy of readings of digital sphygmomanometer in reference to mercury sphygmomanometer in a large population of healthy adults.
METHODS AND MATERIALS
This cross-sectional study was performed on 1119 healthy adults. We measured participant's blood pressure once with mercury sphygmomanometer, as gold standard and again with digital mercury sphygmomanometer. Blood pressure was measured in sitting position after 5 min of rest and preferentially from right arm unless deformed.
RESULTS
The mean ± standard deviation of age of participants was 37.25 ± 10.45 years. Majority of participants were male 588 (52.5%). The right/left SBP measured by digital sphygmomanometer were significantly higher compared with those measured by mercury sphygmomanometer: 115.37 ± 12.33 vs 110.95 ± 10.06/113.69 ± 11.77 vs 110.23 ± 10.34, respectively ( < .001), while an opposite result was observed about right/left DBP: 68.60 ± 8.55 vs 70.60 ± 8.31/69.39 ± 8.31 vs 70.75 ± 8.41, respectively ( < .001). In subgroup analysis in terms of marital status, education, and income, we observed similar findings.
CONCLUSION
According to the results of our data analysis, it was shown that the digital device measurements had significant incompatibility with the mercury sphygmomanometers and it seems that digital devices still cannot be used as the gold standard in blood pressure measurement.

The aim of this work is to develop Merkfree-a mercury-free sphygmomanometer that looks, feels, and operates just like a traditional mercury sphygmomanometer (MS). For this we use Galinstan as a substitute for mercury, which is a non-toxic alloy of Gallium, Indium and Tin. Galinstan is nearly half as dense as mercury and sticks to class. To work with the lower density, we designed an enclosure and scale that is nearly double the length of MS. The issue of stickiness with glass was resolved by maintaining a small meniscus of a reducing agent in the measuring tube and tank of Merkfree. Clinical trials to validate the accuracy of Merkfree against MS and oscillometric sphygmomanometer (OS) were conducted over 252 patients. The results show a good correlation of the systolic and diastolic BP measurements from Merkfree with respect to MS and the OS. The mean absolute percentage error is less than 10% for both SBP and DBP. We also found that Merkfree has lower rounding-off errors compared to MS. Merkfree can be a viable alternative to mercury sphygmomanometer that can help achieve the goal of WHO in eliminating mercury from healthcare, while simultaneously making sure that gold standard technique of sphygmomanometry continues to be available to the clinicians.

BACKGROUND
The tip pinch is one of the most delicate and precise movement of the hand, and it is used to manipulate small objects, commonly observed in the activities of daily living of any individuals. Individuals with Parkinson Disease (PD) with impaired manual dexterity, manipulative skills, and hand weakness have an important barrier for activities of daily life. However, the dynamometer usually used for measuring the tip pinch have a high cost, so, validate a sphygmomanometer can make this assessment more accessible.
OBJECTIVE
To investigate the validity of the modified sphygmomanometer test in the evaluation of tip pinch strength when compared to the gold standard.
METHODS
50 individuals with idiopathic PD took part in the study. The muscle strength of tip pinch on the dominant and non-dominant side was measured by the modified sphygmomanometer test and the gold standard, the dynamometer. Concurrent validity was analyzed using Pearson's correlation coefficient.
RESULTS
50 individuals diagnosed with idiopathic PD, mean age of 67 ± 8.0 years, 68% male, mean time of diagnosis in months of 84 ± 66 and Hoehn and Yahr mean of 2.5 ± 0.6. There was a significant correlation of moderate magnitude between the modified sphygmomanometer test and the dynamometer in dominant side (r = 0.44; p < 0.01) and non-dominant side (r = 0.48; p < 0.01).
CONCLUSION
The modified sphygmomanometer test showed adequate validity for assessing the muscle strength of the tip pinch in individuals with PD.
