A patient with scrotal filariasis was treated with DEC. Which of the following would show that the adult filarial is killed
|A||Disappearance of microfilaria from blood|
|B||Appearance of filarial dance sign on scrotal ultrasound|
|C||Disappearance of filarial dance sign on scrotal ultrasound|
|D||Absence of microfilaria in scrotal fluid|
a. Genital filariasis in India presents commonly as secondary vaginal hydroceles with an associated epididymoorchitis
b. Wuchereria bancrofti is the major species accounting for >98% of filarial cases in India.
c. Acute scrotum is rarely seen in genital filariasis. It is usually caused by secondary bacterial infection of obstructed lymphatic channels
d. Presence of linear echogenic structures with persistent, random, almost tireless twirling movements on high resolution ultrasonography is considered diagnostic of adult filarial worms
e. Ultrasonography is the only modality available currently to assess the response to antifilarial drugs.
f. Filarial dance sign is appreciated on high resolution USG, revealing presence of microfilaria and not adult worm.
g. These microfilariae, which were of the size of 50–100 microns, could be picked up on high resolution USG due to their rapid movements within an ideal acoustic medium and turbulence within the surrounding fluid created by their movement.
