Calibration of Noninvasively Recorded Upper-Limb Pressure Waves To the Editor: The article by Verbeke et al1 raises an important question: how does one calibrate the radial artery waveform obtained by applanation tonometry? Does one apply systolic and diastolic brachial values from the Korotkov technique, the “gold standard”, or does one use an oscillometric wrist technique, despite lack of con...

Brachial plexus injury is known to be one of the most serious upper limb injuries, causes paralysis limbs and changes in activity daily living, with consequence disruption socio-economic problems, depression, hopelessness. Management must done properly. The evaluation examination consist detailed anamnesis on chronological events, complete physical examination, imaging studies, electrophysiolog...

Letters to the Editor will be published, if suitable, as space permits. They should not exceed 1000 words (typed double-spaced) in length and may be subject to editing or abridgment. The article by Segers et al 1 on aortic-radial wave transmission and amplification casts doubt on the present approach to the calculation of central aortic pressure from the radial artery tonomographic waveform; th...

Atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. The present report describes a case of variation of the median nerve observed in the Iranian male cadaver during routine trial dissection. There are three roots for median nerve. Median nerve is formed by joining two lateral and medial cords of brachial plexus. Third root ...
