Aa. Alsulaiman et al., ELECTROPHYSIOLOGICAL FINDINGS IN NEWLY-DIAGNOSED NONINSULIN-DEPENDENTDIABETICS - A PROSPECTIVE-STUDY, Annals of saudi medicine, 17(4), 1997, pp. 399-401
This study reports the electrophysiological findings in patients with
newly diagnosed non-insulin-dependent diabetes mellitus (NIDDM) studie
d in the Neurodiagnostic Laboratory of the King Fahd Hospital of the U
niversity (KFHU), Al-Khobar, Saudi Arabia. Twenty-nine patients (22 ma
les, 7 females, mean ages 47 and 37 years, respectively) were studied
within four weeks of establishing the diagnosis. They were all given n
erve conduction studies by the same examiner. Comparison was made with
data from a group of 64 normal control subjects. In the study patient
s, the mean distal sensory peak latency in milliseconds (ms) +/- stand
ard deviation (SD) was 3.5 +/- 0.41 ms in 35 median nerves, 3.2 +/- 0.
72 ms in 35 ulnar nerves, 1.9 +/- 0.34 ms in 23 superficial radial ner
ves and 3.5 +/- 0.61 in 36 sural nerves. The mean distal motor latency
+/- SD was 4.6 +/- 0.95 ms in 39 median nerves, 3.5 +/- 0.58 ms in 38
ulnar nerves, 4.8 +/- 1.02 ms in 44 tibial nerves and 6.0 +/- 1.08 ms
in 36 peroneal nerves. The electromyogram examination was performed o
n 24 patients and showed evidence of denervation and/or chronic reinne
rvation in seven (29%). The frequency of abnormalities in the studied
peripheral nerves was 60% for median, 63% ulnar, 33% peroneal, 16% tib
ial and 8% sural.
