Patient 4
A 22 year old male was recently in a bicycle accident and is seen in the ED for minor injuries. He was diagnosed with a
mild concussion and his abrasions, minor cuts and bruises were addressed and he was discharged. Upon his follow up
with his PC / primary care provider, he complained of severe excess urination and thirst. Urinalysis results are:
\begin{tabular}{|l|l|l|l|l|l|l|}
\hline
Color & Appearance & pH & SpG & Protein & Blood & Ketones \\
\hline
Pale & Clear & 6.0 & 1.002 & Neg & Neg & Neg \\
\hline
\end{tabular}
SpG = Specifici gravity -- normal 1.001 -- 1.035; normal pH = 4.5-8
Based on the above, what is the most likely diagnosis? Note page 614 in the text may assist you
