Case 1:

Mr. Magdy Salah, a 32 year-old man, was transferred to the emergency room in severe dyspnea. He gave the history of recurrent attacks of dyspnea for the last 10 years, which used to improve by using inhaler.

Answers

 

Case 1:

Answer:   (B)

Endocrine syndromes are seen in 12% ofpatients with lung cancer.

Squamous cell carcinomais associated with PTH-related peptide.

ACTH and ADH secretion can be associated with small cell lung carcinoma.

ACTH-secreting tumors are associated with darkening of the skin and Hypokalemia

 

Case 2:

Answer;  (D)

Respiratory rate >30 is a poor prognostic sign in community-acquired pneumonia. Other patient factors include age greater than 65 years, coexisting illness such as cancer, liver disease, congestive heart failure (CHF), renal disease, systolic BP less than 90 mmHg, temperature greater than 40°C. Laboratory findings associatedwith poor prognosis include arterial pH<7.35, BUN >30, sodium less than 130, glucose>250, and hematocrit <30%. These factors are often used to calculate the PORT (Pneumonia Outcomes Research Team) pneumonia severity index score which can be an aid in making treatment decisions. S. pneumoniae, Legionella, and S. aureus are the pathogens associated with poor prognosis, not Mycoplasma.

Case 3:

 (B) CORRECT.

This is a description of the typical 'Ghon complex' of an initial, or primary, TB infection. The peripheral granuloma does not produce symptoms, but the enlarged lymph nodes may impinge upon airways. Most persons with a primary infection, however, are asymptomatic and the infection goes unnoticed.

Case 4:

(C) CORRECT.

Sarcoidosis is typified by non-caseating granulomas. However, culture of the tissue and a careful search histologically should be made for organisms.

Case 5:

(B) CORRECT.

A Lung abscesses can result from aspiration of oropharyngeal or nasopharyageal contents, where bacterial organisms as part of normal flora can be picked up and transported to the lungs. The straighter bronchus to the right lung is more likely to conduct aspirated material. With septicemia, multiple abscesses are more likely to be present.

Case 6:

(C) CORRECT.

The typical appearance of a viral lung infection is chronic interstitial inflammation.

Case 7:

(C) CORRECT.

Smoking remains the most frequent cause of lung cancer. Lung cancer does, however, occur in nonsmokers. A small cell anaplastic carcinoma, as in this patient, is virtually always seen in smokers.

Case 8:

(C) CORRECT.

Chronic bronchitis is defined clinically as a person who has persistent cough with sputum production for at least 3 months in at least 2 consecutive years. Air pollution and smoking are key causes for chronic bronchitis.

Case 9:

(D) CORRECT.

The large central mass is consistent with a squamous cell carcinoma, which is seen mainly in smokers.

Case 10:

(A) correct.

A bronchopleural fistula typically occurs in the setting of a severe lung trauma.

Case 11:

(B) CORRECT.

The differential diagnosis of a solitary coin lesion most often includes lung cancer (adenocarcinoma most likely), granuloma, or hamartoma.

Case 12:

(B) CORRECT.

This tumor can spread in a pneumonia-like pattern. The lack of a change over time and the absence of a response to antibiotics should suggest a non-infectious process.

Case 13:

Top of Form

(B) CORRECT.

The symptoms and signs are classic. Sarcoidosis often involves the hilar lymph nodes.

Case 14:

(C) CORRECT.

Pulmonary TB is a chronic infection which can form apical abscess with transbronchial spread. 

Case 15:

(A) CORRECT.

Pulmonary abscesses typically have an air-fluid level. More virulent bacterial organisms such as Staphylococcus aureus are likely to cause such a complication of a bronchopneumonia

Case 16:

(D) CORRECT.

In an acute asthmatic episode, there can be an outpouring of mucus which, along with some dehydration, can lead to the formation of mucus plugs. The asthmatic episodes are usually initiated by a type I hypersensitivity reaction, typically with exposure to an allergen such as pollen from goldenrod or other flowering plant. Up to 10% of children may be affected to some degree.

Case 17:

(D) is the correct answer.

Case 18:

(E) CORRECT.

An embolus to a medium-sized arterial branch is not large enough to kill the patient, but large enough to cause an infarction. Her bedridden state predisposes her to deep venous thrombosis and thromboembolism.

Case 19:

(C) CORRECT.

Multiple masses should suggest metastases, rather than a primary lung tumor. His lack of a cough or fever is against an infectious cause or aspiration.

 

 

Case 20:

Top of Form

(A) CORRECT.

An inhaled object could obstruct a bronchus completely, with air resorbtion and collapse of lung distal to the point of obstruction. This produces a shunt defect with a V/Q mismatch. Since there is perfusion but no ventilation, even 100% oxygen will not make a difference. His hyperventilation has acutely produced an uncompensated respiratory alkalosis.

Case 21:

Top of Form

E is correct.

This lady has Chronic Obstructive Airways disease and subsequent Cor Pulmonale leading to right heart failure. Non-bacterial thrombotic endocarditis is a condition seen in frail ill individuals.

Case 22:

C is correct.

This patient has features of acute severe asthma, and should be given oxygen, steroids and nebulised salbutamol as immediate treatment.

 

Case 23:

D is correct.

Immediate treatment of anaphylaxis includes cessation of whatever caused it. Oxygen, fluids and adrenaline/epinephrine 0.5mg i.m or subcutaneously. (checking concentrations of adrenaline is very important especially in high pressure situations). Intravenous adrenaline is potentially hazardous unless diluted appropriately.

 

Case 24:

C is correct.

This patient has PE following a recent haemorrhagic stroke. The risk of rebleeding into the stroke area is too high with anticoagulation. The best action would be percutaneous insertion of IVC filter which may be as effective as anticoagulation. It is used in cases where anticoagulation is a contraindicated or in those in whom anticoagulation alone fails.
