ONLINE BLENDID MONTHLY ASSIGNMENT FOR THE MONTH OF MAY 2021
CARDIO(A). 1.What are the possible causes for heart failure in this patient?
ANS:
obesity
alcohol
diabetes
hypertension
2.what is the reason for anemia in this case?
ANS:
Alcoholics frequently have defective red blood cells that are destroyed prematurely, possibly resulting in anemia. Alcohol also interferes with the production and function of white blood cells, especially those that defend the body against invading bacteria. Consequently, alcoholics frequently suffer from bacterial infections.
3.What is the reason for blebs and non healing ulcer in the legs of this patient?
ANS:
The pt. had recurrent blebs and ulcer on lower limbs (foot). This is due to Type to diabetes mellitus.
Diabetic foot ulcers generally arise as a result of poor circulation in the foot region. While high blood sugar levels and nerve damage or even wounds in the feet may result in foot ulcers in many cases.
In cases of poor circulation of blood, the foot ulcers take quite a bit of time to heal as the blood efficiency in the foot region is at a low level. Furthermore, many develop a bit of reduced sensation on the feet as a result of nerve damage or more.
There are many risk factors that may lead to foot ulcers at the end.
Poor quality or fitting of the footwear.
Unhygienic appearance of foot.
Improper care of the nails of the toe.
Heavy intake of alcohols and tobacco.
Obesity and Weight-related
Complication arising from Diabetes like eye problems, kidney problems and more.
Although aging or old age can also be counted among them.
4. What sequence of stages of diabetes has been noted in this patient?
ANS: alcohol------obesity------impaired glucose tolerance------diabetes mellitus------microvascular complications like triopathy and diabetic foot ulcer-------macrovascular complications like coronary artery disease , coronary vascular disease and peripheral vascular disease.
CARDIO(B). 1.What is the difference btw heart failure with preserved ejection fraction and with reduced ejection fraction?
ANS:
-The amount of blood pumped out of the heart with each beat is called the ejection fraction (EF). A normal EF is usually around 55 to 70 percent, but it can be lessened in some forms of heart failure.
-People with heart failure with reduced ejection fraction (HFrEF) have an EF that is 40 to 50 percent or lower. This is also called systolic heart failure. People with heart failure with preserved ejection fraction (HFpEF) do not have much of a change in their ejection fraction. This is often called diastolic heart failure.
-HFrEF were often diagnosed earlier in life and right after a heart attack.
HFpEF were diagnosed later in life and first experienced symptoms of heart failure between the ages of 65 and 69. Many of those with HFpEF also shared that they have other health problems that led to their diagnosis. Many of them also live with additional health conditions, including acid reflux (GERD), high blood pressure, kidney disease, and sleep disorders.
-HFrEF shared that they feel depressed and/or anxious about their heart failure diagnosis. Risk factors for those in this group include genetics or a family history of heart failure.
HFpEF shared that they are still able to do the things they enjoyed before their heart failure diagnosis.risk factors, including:
Sedentary lifestyle
High blood pressure
Sleep apnea
Other heart conditions
-HFrEF are more likely to have had surgery, including surgery to implant a pacemaker or other heart rhythm control device.HFrEF shared that they currently use a combination therapy to treat their heart failure.
HFpEF have never had surgery to treat their heart failure or had a device implanted.
-HFrEF are men who live in rural areas.
However, most respondents with HFpEF are women who live in urban areas.
2.Why haven't we done pericardiocenetis in this pateint?
ANS;
Pericardiocentesis is done when the pericardial effusion is not resolving on its own . Here the pericardial fluid which has accumulated was resolving on itw own , at the time of admission it was 2.4mm and when discharged it was 1.9 mm . Therefore we did not do pericardiocentesis in this pt.
3.What are the risk factors for development of heart failure in the patient?
ANS: IN THIS PATIENT:
NON MODIFICABLE:
age
gender
MODIFIABLE:
hypertension
smoking
type 2 diabetes .
kidney disease.
IN GENERAL RISK FACTORS:
4.What could be the cause for hypotension in this patient?
ANS:
The pt. was anemic with Hb of 8gm/dl . One of the severe complication of anemia is tissue hypoxia which further lead to hypotension.
NEURO (A).
A 40year old male presented with chief complaints of irrelevant talking and decreased food intake since 9days.
He was conscious but oriented to time, person and place only from time to time.
He also had short term memory loss since 9days, where he couldn't recognize family members from time to time
Previously, he had 2-3episodes of seizures, one being one year ago and the most recent being 4months ago. The most recent one, he had developed seizures following cessation of alcohol for 24hours.
1) what is the evolution of the symptomology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary etiology of the patient's problem?
Ans: The patient is a chronic alcoholic, he drinks about 3-4quarters/day.he had developed seizures following the cessation of alcohol for 24hours it is due to the following reason:-alcohol affects the way in which nerve cells communicate. receptors are specialized proteins on the surface of nerve cells that receive chemical signals from one another. With long-term alcohol consumption, receptors affected by alcohol undergo adaptive changes in an attempt to maintain normal function.
Two important brain communication systems affected by alcohol involve the neurotransmitters:gamma-aminobutyric acid and glutamate.
The GABA system:
GABA is an inhibitory neurotransmitter that helps to regulate brain function by rendering nerve cells less sensitive to further signaling. single doses of alcohol facilitate the inhibitory function of the GABA receptor, contributing to alcohol intoxicating effects. During withdrawal, brain GABA levels fall below normal and GABA activity declines. The combination of reduced brain GABA levels and GABAa receptor sensitivity may be contributed an adaptation to the presence of alcohol. In the absence of alcohol, the resulting decrease in inhibitory function may contribute to Symptoms of nervous system hyperactivity associated with both acute and protracted AW.
The glutamate system:
The major excitatory neurotransmitter in the brain is glutamate, which communicates with three major subtypes of glutamate receptors. Among these, the N-methyl-D-aspartate (NMDA) receptor plays a role in memory, learning, and the generation of seizures. Alcohol inhibits the excitatory function of the NMDA receptor in laboratory studies at concentrations associated with mild to moderate alcohol intoxication in humans. As with the increased inhibitory function of the GABAA receptor, the decreased excitatory function of the NMDA receptor is consistent with alcohol’s general sedative effect. Long-term alcohol administration produces an adaptive increase in the function of NMDA receptors. Acute AW activates glutamate systems. In turn, AW seizures are associated with increased NMDA receptor function. Persistent alterations in NMDA receptor function may potentiate the neurotoxic and seizure-inducing effects of increased glutamate release during withdrawal.
The symptom: irrelevant talking, decreased food intake, tremors, sleep disturbance is due to the following reason: chronic alcohol consumption causes thiamine deficiency due to impaired absorption of thiamine from the intestine, a possible genetic predisposition, inadequate diet, reduced storage of thiamine in the liver and other nutritional deficiencies.
THE PATHOPHYSIOLOGY:
Thiamine, one of the first B vitamins to be discovered also known as Vitamin B1, is a coenzyme that is essential for intricate organic pathways and plays a central role in cerebral metabolism. This vitamin acts as a cofactor for several enzymes in the Krebs cycle and the pentose phosphate pathway, including alpha-keto-glutamic acid oxidation and pyruvate decarboxylation. Thiamine-dependent enzymes function as a connection between glycolytic and citric acid cycles. Therefore, deficiency of thiamine will lead to decreased levels of alpha-keto-glutarate, acetate, citrate, acetylcholine and accumulation of lactate and pyruvate. This deficiency can cause metabolic imbalances leading to neurologic complications including neuronal cell death. Neuronal death in the mammillary bodies and thalamus were implicated in multiple cases of Wernicke encephalopathy studied. Studies involving computed tomography (CT) and magnetic resonance imaging (MRI) of patients with Wernicke encephalopathy revealed lesions in the thalamus with dilated ventricles and volume loss in the mammillary bodies. The lesions are usually symmetrical in the midbrain, hypothalamus, and cerebellum.
The kidneys have an important job as a filter for harmful substances .alcohol causes changes in the function of the kidneys and makes them less able to filter the blood .alcohol also affects the ability to regulate fluid and electrolytes in the body. In addition, alcohol can disrupt hormones that disrupt hormones that affect kidney function .people who drink too much are more likely to have high blood pressure. High blood pressure is a common cause of kidney disease. The increase in levels of urea, creatinine, uric acid leads to uraemic encephalopathy. which causes asterixis.
the deficiency of thiamine and increase in levels of toxins in the body due to renal disease is the primary etiology of the patient's problem.
2)what are the mechanism of action, indication, and efficacy over placebo of each of the pharmacological and nonpharmacological interventions used for this patient?
Ans: I) Thiamine helps the body cells change carbohydrates into energy. It has been used
as a supplement to cope with thiamine deficiency
ii)Lorazepam binds to benzodiazepine receptors on the postsynaptic GABA-A ligand-gated chloride channel neuron at several sites within the central nervous system.it enhances the inhibitory effects of GABA, which increases the conductance of chloride ions into the cell
iii)pregabalin subtly reduces the synaptic release of several neurotransmitters, apparently by binding to alpha2-delta subunits, and possibly accounting for its actions invivo to reduce neuronal excitability and seizures.
iv)Lactulose is used in preventing and treating clinical portal-systemic encephalopathy .its chief mechanism of action is by decreasing the intestinal production and absorption of ammonia.
v)Potchlor liquid is used to treat low levels of potassium in the body.
3)why have neurological symptoms appeared this time, that were absent during withdrawal earlier ? what could be a possible cause for this time?
Due to excess thiamine deficiency and excess toxins accumulation due to renal disease caused by excess alcohol addiction.
4)what is the reason for giving thiamine in this patient?
chronic alcohol consumption causes thiamine deficiency due to impaired absorption of thiamine from the intestine,Thiamine, one of the first B vitamins to be discovered also known as Vitamin B1, is a coenzyme that is essential for intricate organic pathways and plays a central role in cerebral metabolism. This vitamin acts as a cofactor for several enzymes in the Krebs cycle and the pentose phosphate pathway, including alpha-keto-glutamic acid oxidation and pyruvate decarboxylation. Thiamine-dependent enzymes function as a connection between glycolytic and citric acid cycles. Therefore, deficiency of thiamine will lead to decreased levels of alpha-keto-glutarate, acetate, citrate, acetylcholine, and accumulation of lactate and pyruvate. This deficiency can cause metabolic imbalances leading to neurologic complications including neuronal cell death.
5)what is the probable cause for kidney injury in this patient?
The kidneys have an important job as a filter for harmful substances .alcohol causes changes in the function of the kidneys and makes them less able to filter the blood .alcohol also affects the ability to regulate fluid and electrolytes in the body. In addition, alcohol can disrupt hormones that disrupt hormones that affect kidney function .people who drink too much are more likely to have high blood pressure. High blood pressure is a common cause of kidney disease.
6)what is the probable cause for the normocytic anaemia?
alcohol causes iron deficiency or iron overload due its affect on production of new blood cells organs i.e,bonemarrow and the metabolism of iron .alocohol causes a affect on progenitor cells of blood causing decreased WBC .RBC.alochol decreases iron absorption from intestine .
7)could chronic alcohlism have aggravated the foot ulcer formation ?if yes and why ?
yes,As the patient is diabetic the chance of ulcer formation increases .in a patient of chronic alcoholic theimmune system is weak due to the affect on blood cells formation and iron absorption.due to this healing of an ulcer dampens.
NEURO(G)
a)what is myelopathy hand?There is loss of power of adduction and extension of the ulnar two or three fingers and an inability to grip and release rapidly with these fingers. These changes have been termed "myelopathy hand" and appear to be due to pyramidal tract involvement.
D
b)what is finger escape?
Finger escape
Wartenberg's sign is a neurological sign consisting of involuntary abduction of the fifth (little) finger, caused by unopposed action of the extensor digiti minimi. . This finding of weak finger adduction in cervical myelopathy is also called the "finger escape sign".
c)what is Hoffman's sign?
Hoffman's sign or reflex is a test used to examine the reflexes of the upper extremities. This test is a quick, equipment-free way to test for the possible existence of spinal cord compression from a lesion on the spinal cord or another underlying nerve condition
NEURO(C)
What is a seizure?
Cells in the brain send electrical signals to one another. The electrical signals pass along your nerves to all parts of the body. A sudden abnormal burst of electrical activity in the brain can lead to the signals to the nerves being disrupted, causing a seizure. This electrical disturbance can happen because of stroke damage in the brain.
A seizure can affect you in many different ways such as changes to vision, smell and taste, loss of consciousness and jerking movements.
Seizures after stroke
You’re more likely to have a seizure if you had a haemorrhagic stroke (bleed on the brain). Seizures can also be more likely if you had a severe stroke, or a stroke in the cerebral cortex, the large outer layer of the brain where vital functions like movement, thinking, vision and emotion take place.
Some people will have repeated seizures, and be diagnosed with epilepsy. The chances of this happening may depend on where the stroke happens in the brain and the size of the stroke.
Pathogenesis
There are several causes for early onset seizures after ischaemic strokes. An increase in intracellular Ca2+ and Na+ with a resultant lower threshold for depolarisation, glutamate excitotoxicity, hypoxia, metabolic dysfunction, global hypo perfusion and hyper perfusion injury ,(particularly after carotid end arterectomy) have all been postulated as putative neurofunctional aetiologies. Seizures after haemorrhagic strokes are thought to be attributable to irritation caused by products of blood metabolism. The exact pathophysiology is unclear, but an associated ischaemic area secondary to haemorrhage is thought to play a part. Late onset seizures are associated with the persistent changes in neuronal excitability and gliotic scarring is most probably the underlying cause. Haemosiderin deposits are thought to cause irritability after a haemorrhagic stroke.14 In childhood, post‐stroke seizures can occur as part of perinatal birth trauma.
Normally the “consciousness system”—a specialized set of cortical-subcortical structures—maintains alertness, attention and awareness. Diverse seizure types including absence, generalized tonic-clonic and complex partial seizures converge on the same set of anatomical structures through different mechanisms to disrupt consciousness.
GIT(C)
1) What is the most probable diagnosis in this patient?
Differential Diagnosis:
• Ruptured Liver Abscess.
• Organized collection secondary to Hollow viscous Perforation.
• Organized Intraperitoneal Hematoma.
• Free fluid with internal echoes in Bilateral in the Subdiaphragmatic space.
• Grade 3 RPD of right Kidney
The most probably diagnosis is there is abdominal hemorrhage. This will give reasoning to the abdominal distention, and the blood which is aspirated.
2) What was the cause of her death?
After leaving the hospital, the patient went to Hyderabad and underwent an emergency laparotomy surgery. The patient passed away the next day. Cause of her death can be due to complications of laparotomy surgery such as, hemorrhage (bleeding), infection, or damage to internal organs.
3) Does her NSAID abuse have something to do with her condition? How?
NSAID-induced renal dysfunction has a wide spectrum of negative effects, including decreased glomerular perfusion, decreased glomerular filtration rate, and acute renal failure. Chronic NSAIDs use has also been related to hepatotoxicity. While the major adverse effects of NSAIDs such as gastrointestinal mucosa injury are well known, NSAIDs have also been associated with hepatic side effects ranging from asymptomatic elevations in serum aminotransferase levels and hepatitis with jaundice to fulminant liver failure and death.
Nephrology
A) Link to patient details:
1. What could be the reason for his SOB ?
ANS:
- Being short of breath can be related to the kidneys in two ways. First, extra fluid in the body can build up in the lungs. And second, anemia (a shortage of oxygen-carrying red blood cells) can leave your body oxygen-starved and short of breath.
- can it be because of dehydration as the pt. used diuretics ?
- here I am assuming kidney failure lead to diastolic dysfunction which lead to pulmonary congestion leading to SOB.
2. Why does he have intermittent episodes of drowsiness ?
ANS:
A decrease in the renal clearance of waste nitrogenous products accompanies with their continuous generation leads to diverse uremic retention products such as urea, creatinine, guanidine and homocysteine. Many of these toxins affect functioning of cells and organs, resulting in endothelial vascular injury, neurotoxicity and cognitive dysfunction.
Taken from the following article -
3. Why did he complaint of fleshy mass like passage in his urine?
ANS:
The fleshy mass like passage in his urine might be due to excessive pus cells in the urine (according to the reports) and the frothy appearance may be due to the presence of proteins. The urine is pale yellow in colour.
4. What are the complications of TURP that he may have had?
ANS:
- A complication of TURP that the patient may have had is 'TURP syndrome'.
- It is rare but is life threatening.
- Cause- It may occur as a consequence of absorption of fluids used to irrigate the bladder during the operation.
- Signs and symptoms are due to fluid overload and electrolyte disturbances and hyponatremia.
B) Link to patient details:
Questions
1.Why is the child excessively hyperactive without much of social etiquettes ?
ANS:
One possible Provisional diagnosis of this patient is ADHD (Attention deficit/Hyperactive disorder).
Symptoms may start before the age of 12 and include inattention and hyper active impulsive behavior.
Inattention -
They have trouble to stay focused in tasks or play.
They appear not to listen even when spoken directly.
They are easily distracted.
They avoid or dislike tasks that require mental effort.
Hyper active impulsive -
Have difficulty sitting in one place and are always on the run.
Fidget with their hands or legs.
Talk too much
Have difficulty waiting for their turn.
Academic difficulties are frequent as are problems with relationships.
2. Why doesn't the child have the excessive urge of urination at night time ?
ANS:
It maybe Psychosomatic. The child has the urge to urinate in the morning due to stress or mental conflict. During sleep, the kid is free of stress and may not have the urge to urinate excessively.
3. How would you want to manage the patient to relieve him of his symptoms?
ANS:
The only management is reassurance to the kid and his relaxation by reducing stress. The problem will resolve overtime (most commonly by the time he reaches 10yrs).
There are a variety of psychotherapeutic approaches employed by psychologists and psychiatrists; the one used depends on the patient and the patient's symptoms. The approaches include psychotherapy, cognitive-behavior therapy, support groups, parent training, meditation, and social skills training.
