Histiocytic necrotizing lymphadenitis(HNL), also known as Kikuchi-Fujimoto Disease(KFD) is a disease which mainly invades cervical lymph node without any particular reason. Lymphadenopathy can be unilaterally or bilaterally with mild pain and be accompanied with high fever, malaise and skin rashes. At times it shows hepatosplenomegaly, leukopenia and lymphatic cyst. These symptoms will be gone spontaneously without any specific treatments in several weeks or months, so the prognosis is comparatively satisfactory. It is confirmed only by excisional biopsy and must be differentiated from other diseases such as lymphoma, inflammatory and granulomatous lymphadenopathy, etc. Authors report the clinicopathologic findings of 4 cases of HNL with a review of literature.

Audiant bone conductor(ABC) can be beneficial to patients with conductive hearing loss and sensorineural hearing loss. We have implanted ABC for 3 patients with bilateral conductive hearing loss and 2 patients with unilateral profound sensorineural hearing loss. And we evaluated the hearing gain in these patients except 1 case who did not return for follow up. The preoperative average air conduction threshoulds at the three speech frequencies 500, 1000 and 2000Hz, SRT, SD scores were 48.3dB HL, 47.5dB HL, 95% respectively and 19.1dB HL, 20dB HL, 95% postoperatively in 2 patients with bilateral conductive hearing loss. The preoperative average air conduction threshoulds at the three speech frequencies 500, 1000 and 2000Hz, SRT, SD scores were no response, no response, 0% respectively and 42.5dB HL, 51.3dB HL, 60% postoperatively in 2 patients with sensorineural hearing loss.
