Fungal Diseases Trivia Questions
1. Richard Paltauf first described a case of mucormycosis in the middle of which decade?

From Quiz Mucormycosis

Answer: 1880s

Paltauf, a pioneering pathologist, worked with Gustav Scherber to detail various fungal infections. They depicted the first human case of mucormycosis in 1885.

2. How does cryptococcosis usually manifest in immunocompromised hosts?

From Quiz Fungal Respiratory Infections

Answer: Meningitis

Cryptococcosis can also infect the lungs, kidneys, prostate, skin, and bone. It is a common infection in AIDS patients.

3. What is the most common type of mucormycosis?

From Quiz Mucormycosis

Answer: Rhinocerebral

Unfortunately, this nasty disease often attacks the eyes, sinuses, and brain, leading to significant morbidity and mortality. Over 80% of patients with cerebral involvement die.

4. 70% of Mucor infections occur in patients with what disease?

From Quiz Mucormycosis

Answer: Diabetes mellitus

Diabetic ketoacidosis gives a significant predisposition for rhinocerebral mucormycosis, while leukemia makes patients more susceptible to the pulmonary form. Other risk factors for mucormycosis include chemotherapy, AIDS, severe burns, and iron overload. A mere 4% of all cases have no discernable cause.

5. What is the incubation period for cryptococcosis?

From Quiz Fungal Respiratory Infections

Answer: Unknown

The incubation period is unknown. The pulmonary infection can precede brain infection by months or years.

6. What is the only reliable antifungal drug used to combat mucormycosis?

From Quiz Mucormycosis

Answer: Amphotericin B

Azoles (another type of antifungal) are completely ineffective, so extremely high levels of amphotericin B are administered.

7. Approximately how many cases of cryptococcosis are diagnosed annually in the United States?

From Quiz Fungal Respiratory Infections

Answer: 300

It is treated with antifungal agents such as amphotericin B.

8. Mucormycosis can be caused by Mucorales molds. What genus is the most commonly isolated from patients with this condition?

From Quiz Mucormycosis

Answer: Rhizopus

These fungi are normally present in the respiratory tracts of healthy people, as well as in the soil, air, and even moldy bread. Only when a person is immunocompromised in some way can this opportunistic fungus wreak havoc.

9. What is the one hallmark symptom that should alert any doctor to the presence of rhinocerebral mucormycosis?

From Quiz Mucormycosis

Answer: A dry, black scab on the nasal mucosa or palate

Although headache, bulging eyes (proptosis), and loss of extraocular nerve function can occur with this disease, the black scab (known as an "eschar") indicates deep infection and an almost definitive diagnosis.

10. In a histologic examination of biopsied material from a mucormycosis patient, cresyl violet is sometimes used as a stain. What color does Mucor turn when exposed to this solution?

From Quiz Mucormycosis

Answer: Brick red

Other fungi are stained blue or violet, while the walls of Mucor turn red. Most staining techniques are only 20% reliable in showing this fungus; a definitive diagnosis is reached by observing the lack of cross walls within the fungal body, a characteristic that differentiates mucormycosis from aspergillosis (another fungal infection).

11. What is the incubation period for histoplasmosis?

From Quiz Fungal Respiratory Infections

Answer: 3 to 17 days

Most commonly 10 days.

12. What treatment, introduced in 1955, was responsible for the first documented recovery from a battle with mucormycosis?

From Quiz Mucormycosis

Answer: Amphotericin B

Amphotericin B was first isolated from Streptococcus nodosum by Gold, et al., and has been used to treat general fungal infections since 1960.

13. Is 'Pneumocystis carinii' pneumonia (PCP) normally a chronic or acute disease?

From Quiz Fungal Respiratory Infections

Answer: Acute & acute disease

Patients have fever, difficulty in breathing, rapid breathing, dry cough, and cyanosis. It is usually fatal if untreated. It does have a chronic form in some patients suffering from AIDS.

14. An increase in cases of pneumocystis carinii pneumonia (PCP) was one of the early clues in the identification of which disease?

From Quiz Fungal Respiratory Infections

Answer: AIDS

This increase, and the increased demand for drugs to treat PCP, in the 1980s led medical professionals to realize that the cause was a new disease. In the early years of AIDS, the infection often led to death.

15. What is the incubation period for 'Pneumocystis carinii' pneumonia (PCP)?

From Quiz Fungal Respiratory Infections

Answer: Unknown

It is usually treated with TMP-SMX or pentamidine.
