Question 1
What characterizes the healing process in osteomyelitis if the infection is effectively controlled?
Explanation
If the infection is controlled, joint healing often results in fibrous ankylosis, particularly if the articular cartilage is severely damaged; it doesn't always lead to complete recovery of normal bone shape.
Question 2
In congenital syphilis, what is a hallmark skeletal change observed radiographically?
Explanation
Periosteal new bone formation is a characteristic finding in congenital syphilis, as opposed to immediate abscess formation or fractures generally.
Question 3
Which organism is most commonly responsible for acute osteomyelitis in children?
Explanation
Staphylococcus aureus is found in over 70% of acute osteomyelitis cases in children.
Question 4
What is a typical sign of acute osteomyelitis in infants?
Explanation
Infants with osteomyelitis may exhibit pseudoparalysis, refusing to move the affected limb.
Question 5
What is the primary mode of transmission for Congenital syphilis to the fetus?
Explanation
Congenital syphilis occurs when Treponema pallidum crosses the placental barrier during pregnancy.
Question 6
Which condition is characterized by the formation of biofilms on medical implants?
Explanation
Periprosthetic joint infection involves the adherence of microorganisms forming biofilms on implants.
Question 7
What is the classical treatment recommended for acute osteomyelitis?
Explanation
Early and effective antibiotic treatment is crucial for managing acute osteomyelitis.
Question 8
Which of the following factors does NOT predispose an individual to infection?
Explanation
Regular exercise is generally protective against infection, while other options are risk factors.
Question 9
In tropical ulcer, what is the most common cause of the initial skin lesion?
Explanation
Tropical ulcers typically begin from minor skin abrasions that become infected.
Question 10
Which imaging technique is most useful for early detection of joint effusion in septic arthritis?
Explanation
Ultrasonography is effective in revealing joint effusion in early-stage septic arthritis.
Question 11
What common clinical feature may suggest septic arthritis in a child?
Explanation
In children, refusal to use the affected limb typically indicates pain from septic arthritis.
Question 12
What pathophysiological characteristic distinguishes tuberculosis arthritis?
Explanation
Tuberculosis arthritis is characterized by a granulomatous inflammatory response.
Question 13
What is a key difference between pyogenic and tuberculous osteomyelitis?
Explanation
Pyogenic osteomyelitis usually leads to rapid and complete joint destruction, unlike tuberculosis.
Question 14
Which of the following is considered a systemic factor increasing susceptibility to infection?
Explanation
A diminished immune response commonly increases a person's susceptibility to infections.
Question 15
Which of the following is typically NOT a symptom of acute rheumatic fever?
Explanation
Severe abdominal pain is not typical of acute rheumatic fever symptoms, which are distinct.
Question 16
What is an essential aspect of managing patients with chronic osteomyelitis?
Explanation
Regular antibiotic therapy is crucial in managing chronic osteomyelitis.
Question 17
Which of the following is NOT a typical sign of acute osteomyelitis?
Explanation
Excessive joint flexibility is NOT a typical symptom of acute osteomyelitis, which usually restricts mobility.
Question 18
What is the best initial treatment for septic arthritis in adults?
Explanation
Initial treatment for septic arthritis typically involves aspiration of the joint to relieve pressure.
Question 19
Which factor does NOT increase host susceptibility to osteomyelitis?
Explanation
Active inflammatory response is a body mechanism to combat infection; unlike poor circulation, advanced age, and diabetes mellitus, it does not predispose to infection.
Question 20
What is the most common organism found in both children and adults with osteomyelitis?
Explanation
Staphylococcus aureus is the most frequently isolated organism in cases of osteomyelitis among both children and adults.
