The Doctor's Clinical Diary_29-The Time of the Stopped Pons
Prologue: The Weight of Fifteen Years
I am Kim Junho, a doctor who
has been wearing a white coat for fifteen years in the Neurology Department of
a general hospital. The weight of those fifteen years has become a
familiar weariness and an intuition that allows me to grasp the key to a
diagnosis simply by looking into a patient's eyes. While I have
faced countless human sufferings, every new patient's story has a strange power
to make my worn-out heart beat again.
We neurologists are often like
explorers lost in the universe of the brain. Each nerve is an
unknown galaxy, and the symptoms that arise when their function
stops or connects incorrectly are like the scream of the cosmos. Especially
tragedies born from human carelessness and the subtlety of biological balance,
like Central Pontine Myelinolysis (CPM), remain as a bitter lesson deep
in my heart.
This disease, which involves
the destruction of the myelin sheath surrounding the nerve fibers in the
pons—the command center of life in the brainstem—often appears
unexpectedly during treatment processes that are either discovered too late or
are too aggressive. The irony of this illness, which frequently
occurs in patients with chronic alcoholism, is that the
therapeutic action believed to be 'salvation' actually triggers a 'catastrophe'.
Today, I revisit the desperate
medical record of a young man. His story will serve as a warning
and a message of hope to all medical staff, and to everyone who lives unaware
of this danger. This is the most agonizing, yet simultaneously the
most humane, clinical diary of my fifteenth year—a record dedicated to the balance
of life and recovery.
"The
Doctor's Clinical Diary" is not merely a record of curing diseases, but a record of the time spent
confronting the human soul through those diseases.
Chapter 1: Twenty-Six, The Stopped
Speech
1. A Call from the Emergency
Room
"Professor Kim, the
Emergency Room is calling. A 26-year-old male patient. The main
symptoms are a bit unusual. Dysarthria, apathy, and horizontal
nystagmus are observed". The resident's voice on the
phone was tense. Sudden neurological symptoms in a young man of 26.
I immediately thought of an infectious or metabolic problem rather than a
common stroke or trauma. Rushing out of my office, I quickly
reorganized the key chart information in my head.
2. The Shadow of a Young Life
The patient, Mr. Lee Hyunsu
(pseudonym), lay pale on the emergency room bed. His eyes were
unfocused, and his mother was holding his hand with tear-soaked hands.
"Mother, I am Kim Junho, the attending neurologist. Let me examine your
son's condition". Hyunsu's mother spoke with a hoarse voice.
"Doctor... for the past few days, his speech has been strange (dysarthria),
his eyes keep twitching to the side (horizontal nystagmus), and he has
no strength at all. He... actually has a history of chronic alcohol abuse".
The moment I heard those
words, a blaring danger signal went off in my head. Chronic
alcoholism. This is a powerful risk factor for a specific
neurological complication, the most devastating of which is Osmotic
Demyelination Syndrome. "What are the blood test
results?" I asked the resident. "Serum sodium level
is 137 mmol/L, serum osmolality is 287 mOsm/kg. Other clinical test values are
currently within the normal range".
While the sodium level was
currently normal, the patient's past medical history and current symptoms
strongly suggested a severe 'past' event. I knew that Central
Pontine Myelinolysis (CPM) occurs when hyponatremia (low sodium levels) is
corrected too rapidly. Hyunsu must have experienced a severe
electrolyte imbalance just before or prior to arriving at the emergency room,
and it was highly probable that someone had tried to restore that balance too
quickly.
3. The Silence of the Pons
"Hyunsu, can you hear me?
Can you blink your eyes?". He blinked with effort.
As a doctor, I needed to focus on his symptoms, but witnessing a person's life
come to a standstill was always painful.
Dysarthria is a clear sign of brainstem damage, particularly to
the pons. The brainstem, in addition to basic
life-sustaining functions like respiration and heart rate, is where crucial
neural pathways controlling swallowing, speaking, eye movement, and limb
movement pass through. "Mother, were there any other
symptoms? Trouble swallowing, or any weakness in his arms and legs in the past
few days...".
The mother lowered her head.
"A few days ago, he often choked while drinking water. I just thought he
was tired...". I let out a long sigh. Any
further delay was dangerous.
"We must perform an MRI
immediately. Central Pontine Myelinolysis (CPM) is strongly suspected.
This is a disease that causes fatal damage to the pons. Fast and accurate
diagnosis is essential". I struggled with how to deliver the
cruel truth to Hyunsu's mother, whose eyes were filled with anxiety—that there
is no specific treatment for this disease and that we must rely mainly on supportive
care. Since prevention is key, if it has already
occurred, all that remains is patient rehabilitation and time for recovery.
4. The MRI Warning
A moment later, Hyunsu's brain
MRI images were spread out before me.
- Image
A (T1-weighted image): Low signal intensity visible in the center
of the pons.
- Image
B (T2-weighted image): A distinct and high signal intensity visible
in the same area.
I let out a deep sigh as I
looked at the red arrow pointing to the central pontine lesion on the
screen. It was the classic radiological finding for Central
Pontine Myelinolysis (CPM). The lesion, shining white in the
center of the pons as if a heart had stopped, was the trace of the destroyed
nerve cell myelin sheath.
"The diagnosis is
confirmed. Mr. Lee Hyunsu has Central Pontine Myelinolysis.
Severe symptoms such as spastic quadriparesis and pseudobulbar palsy
may occur in the patient within two to five days. Time is of the essence
now".
I looked at his mother.
The shadow cast over her face was the same as the weight of the permanent
disability that was about to befall her young son. But a doctor
cannot succumb to despair.
"Mother, do not give up
hope. CPM is a frightening disease, but through management, we can
minimize the symptoms and recover lost function through rehabilitation.
We will do our absolute best".
Chapter 2: The Five-Day
Tragedy and the Destruction of Balance
1. Rigidity Brought by Silence
Five days had passed since the
diagnosis. Despite my strong warning from the emergency room,
Hyunsu's condition was following the exact path we had feared. The
young body of the 26-year-old was now betraying its owner's will.
I entered Hyunsu's room.
His mother had not left his bedside. I nodded as a greeting, then
carefully examined Hyunsu's arms and legs. Spastic
quadriparesis had begun. His limbs were rigid, and when I
tried to move them according to my intention, there was intense muscular
resistance. It was a typical Upper Motor Neuron symptom resulting
from damage to the motor nerve pathways descending from the brain to the
muscles.
"Mother, his arms and
legs have become very stiff. The quadriparesis, one of the
symptoms we predicted, is progressing". The mother weakly
nodded. "Doctor... since yesterday, he can't speak at all.
His facial expression is... very strange, too".
I examined Hyunsu's face.
His facial muscles were frozen, and emotional expression seemed almost
impossible. The ability to swallow also seemed completely
paralyzed. This was the manifestation of Pseudobulbar Palsy.
This paralysis, which results
from bilateral damage to the pons (superior to the medulla) rather than the
medulla itself, plunges the patient into a desperate state.
Watching the young soul who could not speak, swallow, or naturally express
emotion—only blink his eyes—I felt a profound sense of helplessness.
2. The Doctor’s Confession:
The Paradox of Balance
I escorted the mother to the
consultation room at the end of the hallway. It was time to
frankly explain the essence of the disease.
"Mother, this disease is Central
Pontine Myelinolysis (CPM). It is a neurological disorder
where the myelin sheath surrounding the nerve fibers in the pons—the
most critical part of the brainstem—is destroyed". I drew a
simple picture of the brain and a cross-section of the myelin sheath on the
whiteboard. "This myelin sheath is like the insulation on an
electrical wire (nerve fiber). When this insulation is damaged,
nerve impulse transmission is hindered, leading to symptoms like paralysis and
dysarthria".
The mother tightly held a
handkerchief. "Why... why did this have to happen to my
child? Is it because of the alcoholism?".
"Chronic alcoholism
is an important risk factor, but it is not the direct cause. CPM
is primarily caused by a sudden change in serum sodium levels,
specifically when hyponatremia is corrected too quickly. Individuals
like Hyunsu, who have poor nutritional status due to prolonged alcohol abuse
or who have liver disease, are very susceptible to electrolyte imbalance".
I paused and continued.
"At some point in the past, which would have been difficult for you to
know, Hyunsu must have suffered from severe hyponatremia. And
when someone, or he himself, tried to normalize the sodium levels too quickly,
the brain cells were exposed to osmotic shock. As a result, the
sensitive cells of the pons were damaged. The irony is
that the 'rapid correction' intended to save his life actually caused this
fatal neurological disorder. This is the tragedy of Osmotic
Demyelination Syndrome".
3. Supportive Care and the
Prediction of Long Rehabilitation
The mother was speechless,
sobbing. The most difficult moment for a doctor is when you have
to talk about 'what ifs' after the disease has already taken hold.
"Doctor, then the treatment... can it not be cured?".
I quietly shook my head.
"I will be honest with you. Currently, there is no specific
pharmacological treatment for Central Pontine Myelinolysis treatment.
Our role now is to focus on supportive care. We will
prevent complications and buy time for Hyunsu's brain to recover on its
own".
I explained the concrete plan.
"Since he cannot swallow food on his own due to pseudobulbar palsy, the
insertion of a nasogastric tube for nutritional support is essential.
We must strictly maintain appropriate hydration and electrolyte balance.
And the most important thing to start right now is rehabilitation therapy.
We need to relieve muscle rigidity and restore lost function through physical
therapy".
The prognosis of CPM is
difficult to predict. While there are cases of full recovery,
permanent neurological disability can also remain. Hyunsu
is still young and has remaining recovery potential. My clinical
experience whispered to me not to give up hope.
"Mother, this will be a
long fight. But our medical team will not let go of Hyunsu's hand.
Rehabilitation therapy can be painful and slow, but if we do not give
up, the light will certainly appear. Together, we will help
Hyunsu walk and speak again. The most important thing is your
dedicated support. We must all become facilitators to help
Hyunsu's myelin sheath heal itself".
The mother wiped her tears and
said with difficulty. "Yes... Doctor. I will do everything I
can".
Leaving the consultation room,
I resolved to carefully record this young patient's tragic story in my clinical
diary, so that it could become a case containing the most moving
medical knowledge that warns against the dangers of chronic
alcoholism and electrolyte correction.
Chapter 3: Rehabilitation, A
Small Movement Blossoming in Despair
1. The Silent Room and the
Weight of Time
Two weeks had passed since the
diagnosis of Central Pontine Myelinolysis (CPM) and Hyunsu was trapped
in the desperate symptoms of spastic quadriparesis and pseudobulbar
palsy. The room was filled with palpable tension and silence.
I stood by Hyunsu's side during every daily round.
Outwardly, his condition
seemed unchanged. He still could not speak, could not swallow on
his own, and his limbs were rigid. However, to a neurologist, 'no
change' means 'no regression,' which is grounds for long-term hope.
The eternal prognosis of a patient cannot be hastily judged by the acute-stage
symptoms of this disease. The brain has an astonishing ability to
heal itself, and neural circuits can be reorganized in the very place where the
myelin sheath was destroyed. I focused all treatment on
this small possibility.
"Mother, how was physical
therapy today?". "Doctor... my son is in so much
pain. I feel like his eyes are telling me his muscles hurt.
But just as you said, there's no hope without rehabilitation... so I'm enduring
it".
The mother's face was drawn
from sleepless nights of care and despair. I held her hand and
gave her strength. This is the essence of medical human
stories. We must embrace not only the patient fighting the
illness but also the suffering and endurance of the family watching over them.
2. A Small Sign, Great Hope
That afternoon, the team
leader in charge of Hyunsu's rehabilitation therapy urgently sought me
out. Though he was covered in sweat, his eyes shone with a
strange excitement. "Professor! A very subtle but important
change has been detected in Hyunsu!". "Explain in
detail," I immediately showed interest.
"His quadriparesis
was so severe that moving a single finger was difficult, but today, when I
instructed him to 'move your right thumb,' I saw a very slight... twitching
movement. And more importantly, when I called his name, his eyes
seemed to follow my target without horizontal nystagmus".
Dysarthria and horizontal nystagmus were the main
symptoms Hyunsu exhibited when he first visited. Horizontal
nystagmus signifies the loss of eye movement coordination due to pons
damage. If this movement could be controlled, even slightly, to
follow a target, it was clear evidence that the brainstem function was
recovering, little by little. The prognosis of CPM often
begins with such small changes.
I immediately headed to
Hyunsu's room. "Hyunsu. Listen carefully. I will show you my
finger. Follow it with your eyes". I slowly moved my finger
left and right. Hyunsu's eyes were still slow and labored, but
the meaningless twitching of horizontal nystagmus that he had yesterday
had disappeared, and a faint intention to track my finger was visible.
"Well done, Hyunsu. Very
well done. Now, this is a difficult request, but put strength
into your right thumb and try to move it". Hyunsu frowned as
if concentrating all his strength. And almost imperceptibly, his
right thumb trembled and 'twitched' slightly upward. It was like
a small bubble barely rising to the surface from deep underwater.
3. The Lesson of Medical
Knowledge: Prevention is the Cure
I explained the significance
of this small change to Hyunsu's mother. "Mother, this could
be the beginning of a miracle. CPM is a terrifying
disease, but with supportive care and persistent rehabilitation
therapy, the brain inevitably responds. This subtle movement
is evidence that the brain is forming new neural circuits around the destroyed
myelin sheath".
We decided to intensify the rehabilitation
therapy to seize this small hope. But at the same time, I
knew I could not forget the lesson of this case.
"Mother, Hyunsu's case is
a major warning to everyone. Patients with chronic alcohol
abuse must be especially careful with electrolyte management.
Preventing CPM is far more important than treating it,
and when correcting sodium levels, especially in high-risk individuals, the
change must be gradual and carefully monitored. A sudden
change can create an irreversible pontine lesion like this".
I realized that my role was to
convey medical knowledge to Hyunsu's mother, not merely offer comfort.
His suffering could become a prevention guideline that saves someone
else's life.
My footsteps leaving the room
were no longer heavy. Although Hyunsu was still suffering from dysarthria
and quadriparesis, his spirit had begun to move. The
fifteen years of clinical experience had taught me that human will and the
resilience of life are far greater than the medical knowledge we possess.
I will now accompany Hyunsu on his long journey of recovery.
Chapter 4: Non-Verbal
Communication, The Wall of Rehabilitation
1. New Environment, Unchanging
Struggle
Hyunsu completed his acute
care and was transferred to a rehabilitation hospital for specialized rehabilitation
therapy. My role was to continuously monitor his condition as
his primary physician and coordinate his long-term treatment plan.
Although the room had changed and the environment was different, Hyunsu and his
mother's struggle with Central Pontine Myelinolysis (CPM) was still
ongoing.
Hyunsu's condition was
'desperate but stable'. The spastic quadriparesis
persisted, and the muscles throughout his body stiffened against his will.
Due to pseudobulbar palsy, he still could not utter a sound, and all
nutrition was supplied through a nasogastric tube. The
rehabilitation team carried out intensive physical therapy and occupational
therapy every day. His muscles cried out, but the fact that
he could not express that pain verbally drove Hyunsu into deeper frustration.
I, too, could read the burning agony in his eyes.
2. The Birth of Non-Verbal
Communication
For a patient with pseudobulbar
palsy, the greatest despair is being cut off from the outside world.
Hyunsu's intellect was intact, but the only channels to express that
intelligence to the world—speech, facial expressions, and movement—were
paralyzed. His mother tried desperately to break this wall of
isolation. And we created a communication rule.
"Hyunsu, if you can hear
me, blink once. If you are in pain, blink twice". This
became Hyunsu's sole language to express 'yes,' 'no,' and 'pain'.
One day, his mother said to me
with tears welling up. "Doctor, today I asked my son, 'Do
you... regret that things turned out like this?' And Hyunsu blinked twice. That
meant pain. But then I asked again, 'Do you resent me for trying
to stop you from drinking?' And he didn't blink even once. And
when I asked for the last time... 'Do you want to hold hands and walk with your
mother again?' Hyunsu blinked... blinked... countless times".
It was not just simple
blinking. It was the cry of Hyunsu's soul, breaking through the
shell of language and muscle, and his powerful will for recovery.
I held Hyunsu's hand.
"Hyunsu, your mother is right. We all believe you can walk and speak again.
CPM caused fatal neurological damage to the brainstem, but your
will is stronger than any disease. Our medical team will do our
best with supportive care to help you achieve nerve recovery on
your own".
3. The Doctor's Concern and
the Weight of Responsibility
As a doctor, I must give the
patient hope for recovery, but I must also not hide the realistic prognosis.
A significant number of CPM patients are left with severe quadriparesis
or can even die. Hyunsu's youth was a positive factor, but no one
could predict what the end of this long rehabilitation would be.
I took out his MRI image again.
The pontine lesion shining brightly with T2 signal intensity.
How much of that destroyed myelin sheath could truly be restored?.
The concern over the rapid
correction of hyponatremia, the root cause of CPM, constantly
troubled me. During the initial treatment, someone must have
tried to correct Hyunsu's hyponatremia too quickly. The
fact that a momentary error in judgment by the medical staff—in the face of a
disease where prevention is key—had brought a young man's life to a halt
weighed heavily on me with an enormous sense of responsibility.
Writing this clinical diary, I
hoped that Hyunsu's suffering would become a painful lesson for the medical
community. We must not forget that electrolyte correction is a
life-saving act, yet a dangerous process that can cause osmotic shock.
I needed to constantly emphasize the importance of more cautious and gradual
sodium correction for high-risk patients, such as those with chronic
alcoholism. Hyunsu's blinking was not just communication; it
was a cry demanding deeper responsibility from me.
Chapter 5: A Faint Voice,
Revived Will
1. A Subtle Sound Breaking the
Silence
Two months had passed since
the transfer to the rehabilitation hospital. Every morning, I
checked Hyunsu's chart, trying not to miss even the slightest change.
Central Pontine Myelinolysis (CPM) was a disease that demanded patience
and time from the patient.
That day, when I visited
Hyunsu's room as usual, his mother greeted me with a look of emotion.
"Doctor! This morning, it was a very small sound, but he let out a sound
like 'uh-huh'. Because of his dysarthria, he couldn't even
make a sound from his throat, let alone speak...".
My heart leaped.
The return of voluntary vocalization in a patient with pseudobulbar palsy
was a decisive sign that the neural circuits controlling speech in the
brainstem, especially the pons, were beginning to recover through rehabilitation
therapy and the power of time. This was a greater
breakthrough than the small movement when the horizontal nystagmus disappeared.
I approached Hyunsu.
"Hyunsu, if you can hear me, make an 'Ah' sound. As loud as you can".
Hyunsu clenched his eyes shut, as if gathering all his strength. His
facial muscles were still rigid, but his lips moved slightly. And
finally, a very faint, low sound of 'Aaah...' escaped from deep in his
throat, like a scratch.
2. Breaking the Barrier of
Paralysis
The recovery of vocalization
gave Hyunsu immense mental motivation. He could now convey his
will to the world not only with blinks but also with subtle sounds.
This small success fueled his will to overcome the spastic quadriparesis.
During physical therapy
sessions, Hyunsu was much more active than before. His muscles
were still stiff, but instead of forcing strength, we continued the training to
repeatedly inject the signal 'I can move' into his brain. It was
a process of encouraging the nerve fibers around the myelin sheath
destroyed by CPM to create new detours.
"Hyunsu, now lift your
wrist, not just your finger. You can do it". At the
encouragement of the therapist, Hyunsu gritted his teeth. And his
right wrist resisted gravity, rising just slightly, about 1 centimeter, into
the air. He soon lost strength and it fell with a thud, but that
1 centimeter of movement was a massive piece of evidence of hope for everyone
gathered in the therapy room.
"Look at this, Mother!
Hyunsu's brain is overcoming the paralysis ! Such
spontaneous muscle recovery in patients with Central Pontine Myelinolysis
is truly encouraging". I met the mother's eyes and spoke.
The young life, once overshadowed by chronic alcohol abuse, was
overcoming a desperate neurological disorder through his own will and rehabilitation
therapy.
3. Human Recovery Beyond
Alcoholism
Behind all this recovery was
Hyunsu's internal struggle. The fact that the fundamental cause
of CPM was hyponatremia resulting from chronic alcohol abuse
added significant ethical weight to his recovery.
One day, his mother cautiously
asked me. "Doctor, if Hyunsu gets healthy again, will he
possibly... go back to the way he was?".
I answered firmly.
"Mother, medically, the electrolyte correction issue that caused CPM
has been resolved. But alcoholism is a disease that
requires treatment, not just a habit. The suffering Hyunsu is
going through now must have been the most valuable lesson of his life.
He will not return to that path".
I also asked Hyunsu, through
blinking. "Hyunsu, will you quit drinking for the rest of
your life?". Hyunsu blinked once with all his strength.
'Yes'.
At this moment, I was deeply
moved by the fact that I was not merely a doctor who succeeded in Central
Pontine Myelinolysis treatment, but a facilitator who contributed to the
recovery of a soul. The medical human stories are not just
about curing the disease; they are a record of the patient recovering their
attitude towards life and their will. Hyunsu received an
opportunity to completely change his life through this disease.
I was convinced that this case
would be serialized on Naver Blog and Google Blogspot,
becoming medical knowledge and a moving human story that provides a
warning to those at risk and hope to desperate patients. His
recovery would be a powerful message to the world about the importance of prevention.
Chapter 6: The First Outing,
and the Two Syllables of 'Mom'
1. Shedding the Cloak of
Silence
Three months after the
diagnosis of Central Pontine Myelinolysis (CPM), Hyunsu's room was
filled with hope. Rehabilitation therapy was working
miracles. The spastic quadriparesis still remained, but
his muscle strength and coordination had recovered enough for him to operate a
wheelchair with the help of a physical therapist. The pseudobulbar
palsy and severe dysarthria that had driven him to despair were also
markedly improving.
I complimented Hyunsu on his
recovery. "Hyunsu, your brain is responding to your will.
The nerves around the myelin sheath damaged by CPM have paved a
new path. This is a medical victory and your personal human
victory".
Finally, Hyunsu's first outing
was approved. It was the day he could breathe the air of the
world he had only seen through the hospital room window for three months.
His mother tidied Hyunsu up from early morning, her eyes welling up with tears.
2. The World from a Wheelchair
On the rooftop garden of the
rehabilitation hospital, Hyunsu sat in a wheelchair, basking in the warm
sunshine. The outside air, which he inhaled after three months,
must have felt like the fragrance of life. His mother kept
smiling by his side. It was the moment when light finally found
their lives, which had been trapped under the dark shadow of chronic alcohol
abuse.
I quietly spoke to Hyunsu.
"Hyunsu, the outside air is good, isn't it? Your pons is recovering
its function now. But for complete recovery, consistent supportive
care and rehabilitation therapy will still be necessary.
Do not forget that you must completely break free from alcoholism".
Hyunsu tried to nod, but his
neck muscles were still not free, so his upper body only moved slightly.
But his eyes were clear and full of certainty. I explained to his
mother once again why this CPM case was important. "Hyunsu's
case contains the most important medical knowledge that calls for
caution during electrolyte correction for all patients with hyponatremia,
especially high-risk individuals. It is living proof of
how a sudden osmotic shock can cause fatal neurological damage.
We will continuously record Hyunsu's recovery process to publicize the
importance of prevention".
3. The Miracle of Three
Letters
Before returning to the room
from the rooftop garden, Hyunsu suddenly writhed his body, desperately trying
to express something. Full sentences were still impossible due to
dysarthria, but he struggled to move his lips and tongue muscles to make
a faint sound. The mother focused on her son's lip movements with
a worried face. "Hyunsu, what is it? Water? Are you
thirsty?".
Hyunsu vigorously shook his
head. Tears welled up in his eyes. It was the
frustration of not being able to properly express his will.
I instructed Hyunsu to breathe
slowly. "Slowly, Hyunsu. One syllable at a time, make a
sound slowly". Hyunsu took a deep breath and opened his
mouth again. It was a voice that scratched and cracked, but to
his mother's ears, it was the most beautiful music.
"M...
om."
It was indistinct, but it was
three clear letters. It was the first word directed at his
mother, breaking the three months of silence that pseudobulbar palsy had
suppressed.
The mother sank down right
there and wailed. The tears were a mix of joy, emotion, and
regret for the painful days they had gone through. Watching them,
I realized anew the weight and value of this profession. We are
not just curing diseases; we are restoring human lives and relationships.
I quietly closed the door of
the room and left. Central Pontine Myelinolysis still left
a scar on him, but Hyunsu had begun to communicate with the world again,
stepping over this fatal pontine lesion. His recovery was
slow but certain, and my "The Doctor's Clinical Diary" was now
writing a new chapter of hope.
Epilogue: Finding Balance
1. Discharge, A Door to a New
Beginning
The day Hyunsu left the
hospital, the sky was dazzlingly clear. Six months after the
diagnosis of Central Pontine Myelinolysis (CPM), it was the end of a
long struggle that began in the midst of desperate spastic quadriparesis
and pseudobulbar palsy.
He was still not perfectly
recovered. Dysarthria remained, making his speech unclear,
and he had to walk with a cane, but he had completely shed the past self who
had relied on a wheelchair. On Hyunsu's face as he completed the
discharge procedures, a shadow of deep reflection was cast alongside the
anticipation for a new life.
His mother repeatedly thanked
me, holding my hand. "Doctor... thank you so much.
That my son can speak again and walk on his own feet... it is thanks to your supportive
care and rehabilitation therapy".
I smiled and looked at Hyunsu.
"Hyunsu, your recovery is a miracle created solely by your will and your
mother's dedicated love. My role was just to guide the way.
CPM caused you pain, but your nerve recovery power and will to
live proved stronger than that".
2. The Doctor's Reflection:
Prevention and Introspection
Hyunsu's case remained the
most important clinical record of my fifteen years as a doctor. His
recovery was a joy, but his suffering became a painful lesson that constantly
warned against the medical team's carelessness.
I strongly advocated for
changes in the hospital's electrolyte correction protocol through this
case. The guideline was strengthened to gradually and
carefully monitor the change in serum sodium levels when correcting hyponatremia
in high-risk individuals such as those with chronic alcoholism or
malnutrition. This was because we had learned the hard way that
acute osmotic shock causes a pontine lesion, leading to the fatal
neurological disorder of CPM.
Prevention was far more important than CPM treatment. In
order not to let Hyunsu's misfortune be in vain, we elevated his record into medical
knowledge and serialized it on Naver Blog and Google Blogspot
under the title "The Doctor's Clinical Diary". This writing
garnered a great response as a moving medical human story that warned
readers worldwide about the subtlety of electrolyte balance and the
dangers of alcohol abuse.
3. The Time of the Stopped
Pons, Flowing Again
A few months later, I met
Hyunsu again at a rehabilitation symposium. He could now walk on his own
without a cane, and his dysarthria was so improved that it was barely
noticeable, allowing for short conversations. He smiled brightly when he saw me
and said.
"Professor Kim. I am
now... a completely different person from my former self. The path of chronic
alcohol abuse I walked caused fatal damage to my brain (pontine lesion),
but through this illness, I learned the preciousness of balance. That the most
important things in life are balance and the will to recover".
His words were a perfect
sentence and the cry of a soul that had overcome Central Pontine
Myelinolysis. Through this young patient's journey of tragedy and recovery,
I realized anew that my mission as a doctor goes beyond merely diagnosing
diseases and prescribing medicine—it is about helping patients regain the
balance and hope in their lives.
I will wear my white coat and
head to the neurology ward tomorrow. The clinical diary of my sixteenth year
will be filled with another patient's story, but "The Time of the
Stopped Pons" will forever remain the most thoughtful and moving
record etched into my life as a doctor.
