A comprehensive laboratory testing including white blood cells and platelet counts, sedimentation rate, C-reactive protein, liver and kidney function tests, serum ionogram
, muscular enzymes, folic acid and vitamin B12, thyroid functions, immunoglobulins, and autoantibodies were normal (Table 1).
It is necessary to exclude adrenal insufficiency and perform ACTH, cortisol, aldosterone, plasma renin activity and serum ionogram
testing, which were within the normal range for age in our patient.
The remaining ionogram
, liver function, coagulation screen, and C-reactive protein were within normal limits.
Electron density profile, virtual heights, polarization, and Doppler shift can be obtained according to the ionogram
of 1-30 MHz scanning-frequency results.
Laboratory studies showed normal levels for FAN (Antinuclear Factor), folic acid, Anti-DNA, ionogram
, magnesium, calcium, proteinogram, VDRL, and vitamin B12.
If catatonia is suspected, it is fundamental to monitor closely vital signs, ionogram
, full blood count, and creatine phosphokinase.
We processed the ionogram
traces manually and transferred them to computers, capturing the ionospheric true height profiles for more than 34,000 ionograms
taken in 1999 during high solar activity.
Laboratory variables recorded, when available on the ED, were ionogram
(natremia, serum chloride, kaliemia, alkaline reserve, and blood protein level); serum creatinine; blood cell count; hemoglobin; prothrombin time (expressed as international normalized ratio (INR)); activated partial thromboplastin time (aPTT); liver aminotransferases (AST and ALT); total bilirubin.
From these data, the ionization density, and the maximum usable frequency (MUF) are determined and organized in an ionogram
(graph displaying the virtual height as a function of the frequency for each layer).
For each patient, a thorough medical history is collected along with a complete preoperative work-up, including: complete blood count, urea, creatinine, fasting plasma glucose, alanine aminotransferase, aspartate aminotransferase, serum proteins, serum ionogram
, ionic calcium, magnesium, iron, sodium, kalium, international normalized ratio (INR), activated partial thromboplastin time (aPTT), HIV, HBV and HCV serology, plus 12-lead ECG, blood pressure and heart rate, cardiopulmonary X-ray and breast ultrasound.
Results of initial blood count; ionogram
; and tests for urea, creatinine, and liver enzyme levels were within reference ranges, but slight hypereosinophilia (0.7 x [10.sup.9]cells/L) was noted 1 month later.
