 MEDICINE CASES :

Name: K. Medha Reddy 

Roll no. 51 

Case 1:

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 l 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. 

QUESTION: what is the reason for anaemia in this case?

The patient has normocytic normochromic anaemia. it could be anaemia of a chronic disease as the patient is diagnosed with CKD stage IV.

Chronic kidney disease results in decreased production of erythropoietin which in turn decreases the production of red blood cells from the bone marrow.

Patient’s with anaemia and CKD also tend to have deficiency in nutrients like iron, vitamin B12 and folic acid essential in making healthy red blood cells

 

QUESTION: What is the reason for blebs and non-healing ulcer in the legs of this patient?

The most common cause for blebs and non-healing ulcer in this patient is diabetes mellitus. CKD is also known to cause delay in healing of wounds along with poorly controlled diabetes. Anaemia can also slow down the process of healing due to low oxygen levels.

                                         

QUESTION: What sequence of stages of diabetes has been noted in this patient?

There are 4 stages in type 2 diabetes- insulin resistance, prediabetes, type 2 diabetes and type 2 diabetes and vascular complications, including retinopathy, nephropathy or neuropathy and, or, related microvascular events.

The patient is diagnosed with diabetic triopathy exhibiting sequence of neuropathy, retinopathy and nephropathy

The patient has been diagnosed with diabetic retinopathy, CKD stage IV and shows signs of diabetic neuropathy such as numbness

Case2:

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

Case3: 

Mucormycosis:

QUESTION:  What is the evolution of the symptomatology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary aetiology of the patient's problem?

1.     3 years ago- diagnosed with hypertension

2.     21 days ago- received vaccination at local PHC which was followed by fever associated with chills and rigors, high grade fever, no diurnal variation which was relieved on medication

3.     18 days ago- complained of similar events and went to the the local hospital, it was not subsided upon taking medication(antipyretics) 

4.     11 days ago - c/o Generalized weakness and facial puffiness and periorbital oedema. Patient was in a drowsy state

5.     4 days ago-  

a.     patient presented to casualty in altered state with facial puffiness and periorbital oedema and weakness of right upper limb and lower limb

b.     towards the evening patient periorbital oedema progressed

c.     serous discharge from the left eye that was blood tinged

d.     was diagnosed with diabetes mellitus

6.     patient was referred to a government general hospital 

7.     patient died 2 days ago

 

patient was diagnosed with diabetic ketoacidosis and was unaware that he was diabetic until then. This resulted in poorly controlled blood sugar levels. The patient was diagnosed with acute oro rhino orbital mucormycosis . rhino cerebral mucormycosis is the most common form of this fungus that occurs in people with uncontrolled diabetes ( https://www.cdc.gov/fungal/diseases/mucormycosis/definition.html ) the fungus enters the sinuses from the environment and then the brain.

The patient was also diagnosed with acute infarct in the left frontal and temporal lobe. Mucormycosis is associated with the occurrence of CVA ( https://journal.chestnet.org/article/S0012-3692(19)33482-8/fulltext#:~:text=There%20are%20few%20incidences%20reported,to%20better%20morbidity%2Fmortality%20outcomes. )

 

QUESTION:  What is the efficacy of drugs used along with other non-pharmacological treatment modalities and how would you approach this patient as a treating physician?

The proposed management of the patient was – 

1.     inj. Liposomal amphotericin B according to creatinine clearance 

2.     200mg Iitraconazole was given as it was the only available drug which was adjusted to his creatinine clearance

3.     Deoxycholate was the required drug which was unavailable

https://pubmed.ncbi.nlm.nih.gov/23729001/ this article talks about the efficacy and toxicity of different formulations of amphotericin B 

along with the above mentioned treatment for the patient managing others symptoms is also done by-

       I.          Management of diabetic ketoacidosis – 

(a)   Fluid replacement-  The fluids will replace those lost through excessive urination, as well as help dilute the excess sugar in blood.

(b)   Electrolyte replacement-The absence of insulin can lower the level of several electrolytes in blood. Patient will receive electrolytes through a vein to help keep the heart, muscles and nerve cells functioning normally.

(c)   Insulin therapy-  Insulin reverses the processes that cause diabetic ketoacidosis. In addition to fluids and electrolytes, patient will receive insulin therapy

QUESTION:  What are the postulated reasons for a sudden apparent rise in the incidence of mucormycosis in India at this point of time? 

 Mucormycosis is may be being triggered by the use of steroids, a life-saving treatment for severe and critically ill Covid-19 patients. Steroids reduce inflammation in the lungs for Covid-19 and appear to help stop some of the damage that can happen when the body's immune system goes into overdrive to fight off coronavirus. But they also reduce immunity and push up blood sugar levels in both diabetics and non-diabetic Covid-19 patients. 

With the COVID-19 cases rising in India the rate of occurrence of mucormycosis in these patients is increasing.

Case4:

Cardiology:

1) What is the evolution of the symptomatology 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?

TIMELINE OF EVENTS-

• Diabetes since 12 years - on medication

• Heart burn like episodes since an year- relieved without medication

• Diagnosed with pulmonary TB 7 months ago- completed full course of treatment, presently sputum negative.

• Hypertension since 6 months - on medication

• Shortness of breath since half an hour-SOB even at rest

Anatomical localisation - Cardiovascular system

Etiology:  The patient is both Hypertensive and diabetic , both these conditions can cause

                  - Atherosclerosis: there is build up of fatty and fibrous material inside the wall of arteries.(PLAQUE)

2) What are mechanism of action, indication and efficacy over placebo of each of the pharmacological and non pharmacological interventions used for this patient?

Pharmacological interventions:

TAB MET XL 25 MG/STAT-contains Metoprolol as active ingredient

 MOA: METOPROLOL is a cardiselective beta blocker

 Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause your heart to beat more slowly( negative chronotropic effect)

and with less force( negative inotropic effect). Beta blockers also help open up your veins and arteries to improve blood flow.

Indications: it is used to treat Angina, High blood pressure and to lower the risk of hear attacks .

EFFICACY STUDIES.

Patients were randomized to one of four treatment arms: placebo or ER metoprolol (0.2 mg/kg, 1.0 mg/kg, or 2.0 mg/kg). Data were analyzed on 140 intent-to-treat patients.

Results:  mean baseline BP was 132/78 +/- 9/9 mmHg. Following 4 weeks of treatment, mean changes in sitting BP were: placebo = -1.9/-2.1 mmHg; ER metoprolol 0.2 mg/kg = -5.2/-3.1 mmHg; 1.0 mg/kg = -7.7/-4.9 mmHg; 2.0 mg/kg = -6.3/-7.5 mmHg. Compared with placebo, ER metoprolol significantly reduced systolic blood pressure (SBP) at the 1.0 and 2.0 mg/kg dose (P = .027 and P = .049, respectively), reduced diastolic blood pressure (DBP) at the 2.0 mg/kg dose (P = .017), and showed a statistically significant dose response relationship for the placebo-corrected change in DBP from baseline. There were no serious adverse events or adverse events requiring study drug discontinuation among patients receiving active therapy.

Non pharmacological intervention advised to this patient is: PERCUTANEOUS CORONARY INTERVENTION.

Percutaneous Coronary Intervention  is a non-surgical procedure that uses a catheter (a thin flexible tube) to place a small structure called a stent to open up blood vessels in the heart that have been narrowed by plaque buildup ( atherosclerosis).

3) What are the indications and contraindications for PCI?

     INDICATIONS:

        Acute ST-elevation myocardial infarction (STEMI)

         Non–ST-elevation acute coronary syndrome (NSTE-ACS)

          Unstable angina.

         Stable angina.

         Anginal equivalent (eg, dyspnea, arrhythmia, or dizziness or syncope)

         High risk stress test findings.      

  

   CONTRAINDICATIONS:

     Intolerance for oral antiplatelets long-term.

     Absence of cardiac surgery backup.

      Hypercoagulable state.

      High-grade chronic kidney disease.

      Chronic total occlusion of SVG.

      An artery with a diameter of <1.5 mm.

4) What happens if a PCI is performed in a patient who does not need it? What are the harms of overtreatment and why is research on overtesting and overtreatment important to current healthcare systems?

Although PCI is generally a safe procedure , it might cause serious certain complications like 

A)Bleeding 

B) Blood vessel damage

C) Allergic reaction to the contrast dye used

D) Arrhythmias

E) Need for emergency coronary artery bypass grafting .

Because of all these complications it is better to avoid PCI in patients who do not require it.

⁃ OVER TESTING AND OVER TRAETMENT HAVE BECOME COMMMIN IN TODAY’S MEDICAL PRACTICE.

⁃ Research on overtesting and overtreatment is important as they are more harmful than useful.

Harms to patients

. Performing screening tests in patients with who at low risk for the disease which is being screened.

For example:Breast Cancer Screenings Can Cause More Harm Than Good in Women Who Are at Low Risk. A harmless lump or bump could incorrectly come up as cancer during routine breast screenings. This means that some women undergo surgery, chemotherapy or radiation for cancer that was never there in the first place.

.Overuse of imaging techniques such as X- RAYS AND CT SCANS as a part of routine investigations. 

 Overuse of imaging can lead to a diagnosis of a condition that would have otherwise remained irrelevant - OVERDIAGNOSIS.

Also the adverse effects due to this are more when compared to the benefits.

.Overdiagnosis through overtesting can psychologically harm the patient.

Hospitalizations[41] for those with chronic conditions who could be treated as outpatients[ can lead to economic burden and a feeling of isolation.

Harms to health care systems

The use of expensive technologies and machineries are causing burden on health care systems.

Case5

Gastroenterology:

1) What is the most probable diagnosis in this patient?

àDifferential 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

àThe 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?

àAfter 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? 

àNSAID-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. 

Case6

NEUROLOGY:

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 patients problem?

ANS. Timeline of the patient is as follows-

7 days back- Patient gave a history of giddiness that started around 7 in the morning; subsided upon taking rest; associated with one episode of vomiting

4 days back- Patient consumed alcohol; He developed giddiness that was sudden onset, continuous and gradually progressive. It increased on standing and while walking.

H/O postural instability- falls while walking

Associated with bilateral hearing loss, aural fullness, presence of tinnitus

Associated vomiting- 2-3 episodes per day, non projectile, non bilious without food particles

Present day of admission- Slurring of speech, deviation of mouth that got resolved the same day

Anatomical location- There is a presence of an infarct in the inferior cerebellar hemisphere of the brain.

Etiology- Ataxia is the lack of muscle control or co-ordination of voluntary movements, such as walking or picking up objects. This is usually a result of damage to the cerebellum (part of the brain that controls muscle co-ordination)

Many conditions cause cerebellar ataxia- Head trauma, Alcohol abuse, certain medications eg. Barbituates, stroke, tumours, cerebral palsy, brain degeneration etc.

In this case, the patient has hypertension for which he has been prescribed medication that he has not taken. Stroke due to an infarct can be caused by blockade or bleeding in the brain due to which blood supply to the brain is decreased, depriving it of essential oxygen and nutrients. This process could’ve caused the infarct formation in the cerebellar region of the brain, thus causing cerebellar ataxia.

2)      What are the mechanism of action, indication and efficacy over placebo of each of the pharmacological and non pharmacological interventions used for this patient?

ANS. 

A)     Tab Vertin 8mg- This is betahistine, which is an anti- vertigo medication

MOA- It is a weak agonist on H1 receptors located on blood vessels of the inner ear. This leads to local vasodilation and increased vessel permeability. This can reverse the underlying problem. 

Indications- Prescribed for balance disorders. In this case it is used due to patients history of giddiness and balance issues.

 

B)     Tab Zofer 4mg- This is ondanseteron- It is an anti emetic

MOA- It is a 5H3 receptor antagonist on vagal afferents in the gut and they block receptors even in the CTZ and solitary tract nucleus.

Indications- Used to control the episodes of vomiting and nausea in this patient.

 

C)      Tab Ecosprin 75mg- This is aspirin. It is an NSAID

MOA- They inhibit COX-1 and COX-2 thus decreasing the prostaglandin level and thromboxane synthesis

Indications- They are anti platelet medications and in this case used to prevent formation of blood clots in blood vessels and prevent stroke.

D)     Tab Atorvostatin 40mg- This is a statin

MOA- It is an HMG CoA reductase inhibitor and thus inhibits the rate limiting step in cholesterol biosynthesis. It decreases blood LDL and VLDL, decreases cholesterol synthesis, thus increasing LDL receptors in liver and increasing LDL uptake and degeneration. Hence plasma LDL level decreases.

Indications- Used to treat primary hyperlipidemias. In this case it is used for primary prevention of stroke.

E)      Clopidogrel 75mg- It is an antiplatelet medication

MOA- It inhibits ADP mediated platelet aggregation by blocking P2Y12 receptor on the platelets.

Indications- In this case it decreases the risk of heart disease and stroke by preventing clotting

F)      Thiamine- It is vitamin B1

It is naturally found in many foods in the human diet. In this case, the patient consumes excess alcohol- so he may get thiamine deficiency due to poor nutrition and lack of essential vitamins due to impaired ability of the body to absorb these vitamins.

Indications- Given to this patient mainly to prevent Wernickes encephalopathy- that can lead to confusion, ataxia and opthalmoplegia.

G)     Tab MVT- This is methylcobalamin

Mainly given in this case for vitamin B12 deficiency.

 

3)      Did the patients history of denovo hypertension contribute to his current condition?

 

ANS. A cerebellar infarct is usually caused by a blood clot obstructing blood flow to the cerebellum. High blood pressure that is seen in hypertension (especially if left untreated) can be a major risk factor for the formation of cerebellar infarcts. 

Increased shear stress is caused on the blood vessels. The usual adaptive responses are impaired in this case, thus leading to endothelial dysfunction in this case. High BP can also promote cerebral small vessel disease. All these factors contribute to eventually lead to stroke. 

 

4)      Does the patients history of alcoholism make him more susceptible to ischaemic or haemorrhagic stroke?

 

ANS. Meta analysis of the relation between alcohol consumption and increased risk of stroke has mainly weighed in to the formation of two types- ischaemic and haemorrhagic stroke.

Ischaemic stroke- this is more common. This Is caused by a blood clot blocking the flow of blood and preventing oxygen from reaching the brain

Haemorrhagic stroke- occurs when an aneurysm bursts or when a weakened blood vessel leaks, thus causing cerebral haemorrhage

According to a Cambridge study, heavy drinkers have 1.6 more chance of intracerebral haemorrhage and a 1.8 increased chance of subaracnoid haemorrhage. The adverse effect on BP that is seen due to increased drinking is a major stroke risk factor and increase the risk of heart stroke.

Many studies show that with mild and moderate drinking . the risk of ischaemic stroke decreases due to decreased level of fibrinogen which helps in the formation of blood clots. However, heavy alcohol intake is associated with impaired fibrinolysis, increased platelet activation and increased BP and heart rate. 

So In this case, his history of alcoholism, coupled with his hypertension definitely could be a causative factor of his current condition

Case7

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.
