Discussion:

Regarding Acute Pulmonary Edema

Regarding Acute Pulmonary Edema, answer the following questions:

1. What are the two most common underlying mechanisms of pulmonary edema?
2. What are the most common causes of acute cardiogenic pulmonary edema?
3. What is the immediate treatment of acute cardiogenic pulmonary edema?

Answers:

1. What are the two most common underlying mechanisms of pulmonary edema?
Acute pulmonary edema can have a cardiogenic or noncardiogenic etiology.
In cardiogenic pulmonary edema, a high pulmonary capillary pressure is responsible for the transudation of protein-poor fluid into the lungs caused by an imbalance of Starling's forces. With acute rises in pulmonary capillary pressure, the pulmonary lymphatics cannot rapidly increase the rate of fluid removal; as a result, pulmonary edema occurs.

Discussion
1. What is the definition of chronic urticaria?
Chronic urticaria is defined as urticaria that persists for 6 weeks or more.

2. What is the pathogenesis of chronic urticaria?
The pathogenesis of chronic urticaria includes a spectrum of events. Commonly, there is simple local edema and itching caused by the release of histamine from mast cells. Other more severe cases have an inflammatory component, such as vasculitis that is revealed by biopsy specimens. In these cases, the responsible mechanism may be either tumor necrosis factor α- leased from activated mast cells,

Case Scenario: A 28-year-old man with a history of intravenous drug abuse presents with a 6- week history of recurrent sweats and weight loss. He comes to the Emergency Department because he is feeling increasingly unwell.
On examination he is tachycardic and has a swollen, hot and tender left knee joint and a faint pansystolic murmur at the left sternal edge.
You are called to assess him.
1. How will you approach to this case.?
2. Give the important points to ask in history?
3. What examination would be important?
4. Give the Differential diagnosis?
5. The investigations that would help in the diagnosis?

Discussion:
In the presence of a murmur, whether new or not, the diagnosis of Infective endocarditis (IE) must be the favored differential diagnosis. Also the use of intravenous drugs in the patient presented in the scenario favors towards a diagnosis of Infective endocariditis.

A careful history and examination are essential to help rule out other non infective and non-cardiac causes for his symptoms, although these would clearly be very unlikely in this case.

History of the Presenting problem: The history (and examination) will be dominated by consideration of the most likely diagnosis (IE), but clues may emerge that take you in another direction. Keep in mind the other differential diagnosis( given below) as you take the history and examine the patient.

Determine the severity of the patient’s condition. In acute IE, the fever is high with rigors and prostration.

B. Beta-blockers
C. Calcium-channel antagonists
D. Diuretics
E. Alpha-blockers

Answer:

Approach To A Patient Who Presents To ER After A Fall. (Case Study)

A 52-year-old male presents to your ED via ambulance complaining of a headache after a fall. He was working and fell approximately 10 feet. He notes no injury except for head and neck pain. A quick survey reveals that he has a BP of 128/86, pulse 100, and respiration 12. There was no loss of consciousness at the scene. He “saw stars” and was clumsy, dazed, and
slow at the scene without any focal neurologic deficit. He is now back to his baseline.

A concussion is defined as:
A) Any neurologic symptoms (e.g., clumsy, dazed, or slow) after head injury.
B) Loss of consciousness followed by return to baseline.
C) Loss of consciousness with continued neurologic symptoms.
D) Requires confusion after head trauma regardless of whether the patient lost consciousness or not.
E) Any traumatic injury to the head.

Answer And Discussion
The correct answer is “A.” Any neurologic symptoms (e.g., clumsy, dazed, or slow) after head injury.

A concussion is defined as any neurologic symptom after head trauma. Note that a concussion does not require a loss of consciousness. For this reason, “B” and “C” are incorrect.
“D” is incorrect because manifestations of concussion are not limited to confusion but also include protracted vomiting, transient amnesia, slowed mentation, “dizziness,” and other neurologic symptoms.
“E” is incorrect because by definition, a concussion requires neurologic symptoms.

* *
Your patient opens his eyes on his own, follows commands, answers all orientation questions correctly, but appears unsteady when ambulating.
His Glasgow Coma Scale (GCS) is:
A) 5.
B) 10.
C) 14.
D) 15.
E) 20.

test to perform?
A. ESR
B. Ferritin
C. Blood glucose
D. Urea and electrolytes
E. Liver function tests

Answer:

Explanation to a patient who is reluctant to receive treatment

Case Scenario: You are a junior doctor in a medical outpatient clinic. A 30 year old female who has come for a prescription of an oral contraceptive pills is found to have high blood pressure. Her BP has been measured on several occasions and found to be consistently in the region of 180/100 mmHg. It has been explained to her that she has high BP that requires investigation and treatment, but she feels well and only wants a prescription for the oral contraceptive pill, not any tests or medication.
Your task is to inform the patient why investigations and treatment are required.

Key issues to explore
The key to a successful outpatient consultation will be to understand the reason why the patient does not want further investigation or treatment.

Does she feel that investigation and treatment are unnecessary because she feels well?
Is she afraid of what may be found?
Is she concerned about the effects of treatment?

Key points to establish

It is very important to establish a rapport with this woman so that she will trust you and thus hopefully follow the recommended management plan.
Explain to her that hypertension is a common and often asymptomatic condition that is frequently detected on routine screening, or incidentally as part of investigations for other medical problems.
It is important that she understands what hypertension is and why it should be taken seriously, even in the absence of any complaints or limitations: the potential harmful effects of long term high BP must be explained.
She will need reassurance and an explanation that investigations are necessary to exclude a secondary cause of high BP, which might mean that the hypertension can be cured and that she would not need long term treatment.
If no specific cause for hypertension is found, then simple changes to her lifestyle may be adequate to treat her BP. But in some situations this is not enough and she may require medication.
Your advice should be accompanied by provision of reading material and help with associated programmes for smoking cessation, weight loss and dietary advice.
