Disorders Part – 1

Acute Coronary Syndrome
Acute Coronary Syndrome (ACS) is a term used to describe a range of conditions related to reduced blood flow to the
heart muscle due to the partial or complete blockage of one or more of the coronary arteries
...
Other symptoms may include shortness of breath, nausea, lightheadedness, or profuse
sweating
...

There are three main types of ACS:
1
...


3
...
It occurs when there is a sudden reduction in blood flow to the
heart due to a partially blocked coronary artery
...
However, it is still a warning sign of potential further heart issues
...
This is usually confirmed by blood tests that detect
cardiac markers in the bloodstream
...
It occurs when there is a
complete blockage of a coronary artery, resulting in significant damage to the heart muscle
...
It's a medical emergency that requires
immediate treatment, often involving procedures like percutaneous coronary intervention (PCI) or thrombolytic
therapy to open the blocked artery and restore blood flow
...

If you or someone you know is experiencing symptoms of ACS, it's crucial to seek immediate medical attention
...


Acute Leukemia
Acute leukemia is a type of cancer that affects the blood and bone marrow
...
These abnormal cells interfere
with the production of normal blood cells, leading to a decrease in the number of red blood cells (anemia), platelets
(thrombocytopenia), and normal white blood cells (neutropenia)
...

...
ALL is most commonly diagnosed in children,
but it can occur in adults as well
...
AML is more common in adults but can also occur in children
...

Symptoms of acute leukemia can vary, but they often include:



Fatigue
Weakness
Paleness
Frequent infections
Easy bruising and bleeding
Bone and joint pain
Enlarged lymph nodes, liver, or spleen
Fever
Weight loss
The diagnosis of acute leukemia is confirmed through blood tests, bone marrow aspiration, and biopsy
...
The specific treatment approach depends on the subtype of leukemia, the patient's age and
overall health, and other factors
...
Advances in medical research and treatment have significantly improved the
outlook for many patients with acute leukemia, especially in the case of children with ALL, where cure rates are
relatively high
...
The adrenal glands, which are located on top of each
kidney, play a crucial role in producing hormones that regulate various bodily functions
...


2
...
In Addison's disease, cortisol production is reduced, leading to symptoms such as fatigue, weakness, weight
loss, and low blood pressure
...

Aldosterone: Aldosterone is responsible for maintaining the balance of salt and water in the body
...

The primary causes of Addison's disease include autoimmune destruction of the adrenal cortex, infections (such as
tuberculosis or fungal infections), certain medications (e
...
, long-term corticosteroid use), and, rarely, genetic factors
...

Symptoms of Addison's disease may develop slowly and can be vague, but they often include:




Fatigue
Weakness
Weight loss
Skin hyperpigmentation (bronzing of the skin)
Low blood pressure
Salt cravings
Nausea and vomiting
Muscle and joint pain
Diagnosing Addison's disease typically involves blood tests to measure hormone levels, including cortisol and
aldosterone
...

The main treatment for Addison's disease is hormone replacement therapy, which involves taking medications to
replace the missing cortisol and aldosterone
...

...
It's essential to adjust
medication dosages during periods of stress or illness to prevent adrenal crisis, a life-threatening condition caused by
severely low cortisol levels
...
However,
ongoing medical care and adherence to prescribed medications are crucial to managing this condition effectively
...
It occurs
when tissue that normally lines the inside of the uterus (endometrial tissue) starts to grow into the muscle layer of the
uterus
...

Here are some key points about adenomyosis:

...


5
...
The severity
of symptoms can vary among individuals, and some women may experience no noticeable symptoms
...
It often occurs in women who have had children and is more common in women in their 30s and 40s
...

Diagnosis: Diagnosis of adenomyosis usually involves a combination of a physical examination, medical history
review, and imaging studies, such as ultrasound or magnetic resonance imaging (MRI)
...

Treatment: Treatment for adenomyosis depends on the severity of symptoms and the patient's age and desire for
future pregnancies
...
g
...
Hysterectomy is a definitive treatment for adenomyosis but should only be
considered if other treatments have failed, and the patient does not wish to have more children
...
The extent to which it
impacts fertility can vary from person to person
...

It's important to consult with a healthcare provider if you suspect you have adenomyosis or are experiencing
symptoms like heavy menstrual bleeding or pelvic pain
...


Adrenoleukodystrophy
Adrenoleukodystrophy (ALD) is a rare and inherited genetic disorder that primarily affects the nervous system and the
adrenal glands
...

Key features and facts about Adrenoleukodystrophy (ALD) include:
1
...


3
...

5
...


Genetic Cause: ALD is caused by mutations in the ABCD1 gene, which is located on the X chromosome
...
However, females who carry a single copy of the mutated
gene (X-linked carriers) can pass the condition on to their male offspring
...
It causes progressive neurological deterioration, leading to loss of motor and cognitive
functions
...
It primarily affects the spinal cord and peripheral nerves, resulting in weakness, stiffness,
and difficulty with coordination
...
The adrenal
glands are responsible for producing hormones like cortisol and aldosterone
...

Diagnosis: ALD is typically diagnosed through genetic testing and specialized imaging studies, such as magnetic
resonance imaging (MRI) to evaluate changes in the white matter of the brain
...
In the case of
adrenal insufficiency, hormone replacement therapy is essential
...
Early detection through newborn screening can be crucial for
better outcomes in individuals with ALD
...
This can be particularly important for improving the outcomes of
boys with cerebral ALD
...
Management and
treatment require a multidisciplinary approach involving neurologists, endocrinologists, and other specialists
...


Angina Pectoris
Angina pectoris, commonly referred to as angina, is a medical term for chest pain or discomfort that occurs when the
heart muscle does not receive an adequate supply of blood and oxygen
...

There are two primary types of angina:
1
...
It occurs predictably, often during physical activity,
emotional stress, or other situations that increase the heart's demand for oxygen
...


2
...
It can occur at rest or with minimal physical
exertion and is typically not relieved by rest or medications
...

The main cause of angina is the narrowing of the coronary arteries due to atherosclerosis, a condition characterized
by the buildup of plaque (cholesterol, fat, and other substances) on the artery walls
...
Other factors that can trigger angina or make it worse
include emotional stress, cold weather, heavy meals, or exposure to smoke
...

Pain that may radiate to the arms, neck, jaw, shoulder, or back
...

Nausea
...

Diagnosis of angina typically involves a thorough medical history, physical examination, and various tests, including
electrocardiography (ECG or EKG), stress tests, coronary angiography, and sometimes non-invasive imaging studies
like echocardiography or myocardial perfusion scans
...
Common treatments and management strategies include:

1
...

3
...

Medications: Doctors may prescribe medications such as nitroglycerin, beta-blockers, calcium channel blockers, and
antiplatelet drugs to alleviate symptoms and reduce the risk of heart-related events
...

Managing angina is essential to reduce the risk of serious heart-related complications
...


Anti - NMDAR Encephalitis
Anti-NMDA receptor encephalitis is a rare autoimmune neurological disorder that primarily affects the central nervous
system (brain and spinal cord)
...
The NMDA receptor
is essential for normal brain function, and the immune system's attack on these receptors can lead to a wide range of
neurological and psychiatric symptoms
...


Symptoms: The symptoms of anti-NMDA receptor encephalitis can vary widely but often progress through stages
...
Over time, neurological symptoms may develop, including seizures,
movement disorders, speech dysfunction, and autonomic instability (problems with heart rate and blood pressure
control)
...


3
...


5
...


Causes: The cause of anti-NMDA receptor encephalitis is believed to be the production of antibodies that target the
NMDA receptors in the brain
...
It can occur in
people of all ages, but it is more common in younger individuals, particularly women
...
An early diagnosis is
crucial because the condition is treatable, and prompt intervention can improve outcomes
...
In severe or refractory
cases, the removal of tumors (if present) and treatment with medications like rituximab or cyclophosphamide may be
necessary
...

Prognosis: With early diagnosis and appropriate treatment, many individuals with anti-NMDA receptor encephalitis
can recover, although recovery can be slow and may involve rehabilitation
...

Recurrence: Some individuals may experience a relapse of symptoms, which underscores the importance of ongoing
medical monitoring and treatment
...
It highlights the role of autoimmune
mechanisms in causing neurological and psychiatric symptoms and the importance of early diagnosis and appropriate
treatment to improve outcomes
...


Aortic Valve Stenosis
Aortic valve stenosis is a heart condition characterized by the narrowing of the aortic valve, one of the four valves in
the heart
...
When the aortic valve is stenotic, it does not
open fully, obstructing the flow of blood from the heart into the aorta
...


2
...


4
...
The most common cause
in developed countries is age-related calcification
...
Common symptoms include chest pain (angina), shortness of breath, fatigue, and fainting
(syncope)
...

Diagnosis: Diagnosis typically involves a physical examination, listening to the heart sounds with a stethoscope (a
characteristic heart murmur is often present), and additional tests such as echocardiography, which provides detailed
images of the heart and the aortic valve
...
Treatment options may include:
 Medical management: In asymptomatic cases, regular monitoring may be recommended
...

 Aortic valve replacement: This is the definitive treatment for severe symptomatic aortic valve stenosis
...
TAVR is a less invasive procedure suitable for certain patients, while
traditional surgery is required in other cases
...
However, it is not a
permanent solution and is generally reserved for specific cases
...


Prognosis: With timely diagnosis and appropriate treatment, the prognosis for patients with aortic valve stenosis is
generally favorable
...

Aortic valve stenosis is a progressive condition, and it is essential for individuals with this condition to receive regular
medical evaluation to monitor its progression and consider intervention when appropriate
...


Arterial Septal Defect
An atrial septal defect (ASD) is a congenital heart defect that involves an abnormal opening or hole in the wall
(septum) between the two upper chambers of the heart, known as the atria
...

Key points about atrial septal defects (ASD) include:
1
...


3
...


5
...


Types of ASD: There are several types of ASD, but the most common is the secundum atrial septal defect, which is
usually located in the central part of the atrial septum
...

Symptoms: The severity of symptoms associated with an ASD can vary, and some individuals may be entirely
asymptomatic
...
In some cases, an ASD can be associated with a heart murmur that a
healthcare provider may detect during a physical examination
...
These tests can help determine the size and location of the defect
and evaluate its impact on heart function
...
Potential complications include pulmonary hypertension (high blood pressure in the lung arteries), heart failure,
arrhythmias, and an increased risk of stroke
...
Small ASDs that do not cause symptoms may not require treatment but should be monitored
regularly
...
The goal of treatment is to prevent complications and restore
normal heart function
...
The prognosis is generally excellent for those who receive timely intervention
...
Early detection and management can help prevent complications and
ensure a good quality of life
...
This disorder is often characterized by a sudden onset of facial drooping and difficulty in controlling
the facial muscles
...

Key points about Bell's palsy include:

1
...


3
...


5
...


Symptoms: The most common and noticeable symptom of Bell's palsy is facial weakness or drooping, usually on one
side of the face
...

Causes: The exact cause of Bell's palsy is often unclear, but it is thought to be related to viral infections, particularly
the herpes simplex virus (HSV)
...
Other factors that
may contribute include stress, trauma, or autoimmune disorders
...
Doctors may
perform tests to rule out other potential causes of facial weakness or nerve disorders, such as a stroke or a tumor
...
However,
healthcare providers may recommend treatments to help speed up the recovery process or manage symptoms
...

Prognosis: The prognosis for Bell's palsy is generally favorable, with most individuals experiencing improvement in
their symptoms within a few weeks to several months
...

Complications: While most people recover without complications, Bell's palsy can lead to problems like synkinesis,
which is the unintentional movement of one part of the face when trying to move another, and rarely, permanent
facial weakness
...
While most cases resolve on their own, prompt evaluation and appropriate treatment can
help ensure a more complete and rapid recovery
...
It involves the noncancerous growth of the prostate gland,
which surrounds the urethra, the tube through which urine and semen exit the body
...

Key points about Benign Prostatic Hyperplasia (BPH) include:
1
...


3
...


Symptoms: BPH can cause a variety of urinary symptoms, which may include:
 Frequent urination, especially at night (nocturia)
 Difficulty starting and stopping urination
 Weak urine stream
 Dribbling at the end of urination
 Urgency to urinate
 Incomplete bladder emptying
Causes: The exact cause of BPH is not fully understood, but age-related hormonal changes, particularly changes in
levels of the male hormone dihydrotestosterone (DHT), are thought to play a role in the development of the
condition
...
Imaging
tests, such as ultrasound or a cystoscopy (a thin tube with a camera), may also be used to assess the severity of the
condition
...

Treatment options may include:
 Watchful waiting: If the symptoms are mild and not bothersome, a healthcare provider may recommend
regular monitoring without immediate intervention
...
These include
alpha-blockers, 5-alpha reductase inhibitors, and phosphodiesterase-5 inhibitors
...


Minimally invasive procedures: For moderate to severe cases, minimally invasive procedures like
transurethral resection of the prostate (TURP), laser therapy, or transurethral microwave thermotherapy
(TUMT) may be recommended to remove or reduce excess prostate tissue
...

Prognosis: With appropriate treatment, most men with BPH experience significant improvement in their symptoms
...

Benign Prostatic Hyperplasia is a common condition among older men, and it is not related to prostate cancer
...


Breast Cancer
Breast cancer is a type of cancer that begins in the cells of the breast
...
Breast cancer can originate in various parts of the breast, including the ducts that
carry milk to the nipple (ductal carcinoma) or the glands that produce milk (lobular carcinoma)
...

Key points about breast cancer include:
1
...


3
...


5
...


7
...


Risk Factors: Various factors can increase the risk of developing breast cancer, including age, family history, certain
genetic mutations (like BRCA1 and BRCA2), personal history of breast cancer, exposure to estrogen, obesity, and
radiation exposure
...

Types: There are several types and subtypes of breast cancer, and the treatment and prognosis can vary depending
on the specific type
...
Other types include invasive lobular
carcinoma, inflammatory breast cancer, and various less common subtypes
...

Early breast cancer may not cause any symptoms and is often detected through screening
...

Staging: The stage of breast cancer describes the extent of the disease and helps guide treatment decisions
...

Treatment: Treatment for breast cancer depends on the type, stage, and other factors, including the individual's
overall health
...

Treatment may also include lymph node removal
...
Early detection and treatment
offer the best chance of a good outcome
...

Prevention: Reducing the risk of breast cancer can involve lifestyle changes such as maintaining a healthy weight,
regular exercise, limiting alcohol consumption, and avoiding smoking
...

Regular breast self-exams, clinical breast exams, and mammography are important for early detection
...


Brown Sequard Syndrome
Brown-Séquard syndrome, also known as Brown-Séquard's hemiplegia, is a neurological condition that results from a
spinal cord injury or lesion that affects one side of the spinal cord
...
The hallmark of Brown-Séquard syndrome is a
combination of motor and sensory deficits on one side of the body, often resulting in a distinct pattern of symptoms
...


2
...


4
...


Symptoms: The symptoms of Brown-Séquard syndrome depend on the location and severity of the spinal cord
injury
...

 Ipsilateral loss of proprioception: Proprioception is the sense of the body's position and movement, and
its loss on the affected side can lead to difficulty with coordination and balance
...

Causes: Brown-Séquard syndrome is most commonly caused by a traumatic injury to the spinal cord, such as a
gunshot wound, stabbing, or a spinal cord contusion from a car accident
...

Diagnosis: The diagnosis of Brown-Séquard syndrome is based on clinical evaluation, medical history, and imaging
studies, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, to identify the location and
extent of the spinal cord injury
...
Depending on the severity, treatment may include surgery, immobilization, pain
management, and rehabilitation
...

Prognosis: The prognosis for individuals with Brown-Séquard syndrome varies depending on the location and extent
of the spinal cord injury and the effectiveness of treatment
...

Brown-Séquard syndrome is a relatively uncommon condition and is often the result of traumatic spinal cord injuries
...

...


Myxoma: Myxomas are the most common type of benign cardiac tumor
...
Myxomas can obstruct blood flow and cause symptoms like shortness
of breath, chest pain, and palpitations
...
They are composed of fatty tissue and are usually located
in the atrial septum
...

Fibroelastoma: Fibroelastomas are small, benign tumors that can be found on heart valves, typically the aortic valve
...
These tumors are usually asymptomatic but can lead to complications
if they dislodge and cause embolisms
...
They
are composed of cardiac muscle cells and can lead to various cardiac issues
...
Sarcomas are the most common type of malignant cardiac tumor and can arise from various types of
heart tissue
...

Diagnosis of cardiac tumors often involves imaging studies such as echocardiography, cardiac MRI, or CT scans
...
Benign tumors can often
be surgically removed, which can provide a cure
...

It's important to note that cardiac tumors are relatively rare, and many heart-related symptoms are not due to tumors
...


Cardiomyopathy
Cardiomyopathy is a general term that refers to diseases of the heart muscle, where the heart muscle becomes
abnormal or dysfunctional
...
There are several types of cardiomyopathy, including:
1
...


Dilated Cardiomyopathy (DCM): In DCM, the heart chambers become enlarged and weakened
...
DCM can be caused by various factors, including genetic mutations, viral infections, and long-term alcohol
abuse
...
This thickening can obstruct blood flow out of the heart and lead to symptoms like chest pain, fainting,
and arrhythmias
...


3
...


5
...
This can lead to symptoms such as fatigue, swelling, and shortness of
breath
...

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC): ARVC primarily affects the right ventricle of the heart
and is characterized by the replacement of heart muscle with fatty and fibrous tissue
...

Unclassified/Cardiomyopathies of Mixed Phenotype: Some forms of cardiomyopathy do not fit neatly into one of
the above categories
...

Diagnosis of cardiomyopathy typically involves a combination of medical history, physical examination, imaging tests
(such as echocardiography, MRI, or CT scans), and cardiac function tests (like electrocardiograms and cardiac
catheterization)
...
It may include lifestyle
modifications, medications, and, in some cases, procedures like implantation of a pacemaker or implantable
cardioverter-defibrillator (ICD), or even heart transplantation in severe cases
...


Cauda Equina Syndrome
Cauda equina syndrome (CES) is a medical emergency that occurs when the bundle of nerves at the lower end of the
spinal cord, known as the cauda equina, is compressed or damaged
...
"Cauda equina" is
Latin for "horse's tail," which describes the appearance of the nerve roots as they branch out from the end of the
spinal cord
...

2
...

...

Bowel and Bladder Dysfunction: Individuals with CES may experience urinary incontinence, loss of bowel control, or
difficulty urinating
...

Lower Extremity Weakness: Muscle weakness or numbness in one or both legs can occur
...

Cauda equina syndrome is a medical emergency because, if left untreated, it can lead to permanent neurological
damage, paralysis, or loss of bowel and bladder control
...


The treatment of CES typically involves decompressive surgery to relieve the pressure on the cauda equina nerves
...
After surgery,
rehabilitation and physical therapy may be necessary to help individuals regain function and mobility
...


Clinical Depression
Clinical depression, often referred to as major depressive disorder (MDD), is a common and serious mental health
condition characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in activities
...

Key features of clinical depression include:
1
...
