Ivermectin is currently approved for treatment of both clinical and veterinary infections by nematodes, including Onchocerca cervicalis in horses and Onchocerca volvulus in humans. However, ivermectin has never been shown to be effective against bacterial pathogens. Here we show that ivermectin also inhibits infection of epithelial cells by the bacterial pathogen, Chlamydia trachomatis, at dose...

A histopathological study of ventral midline skin from midwestern U.S. horses with and without onchocerciasis due to Onchocerca cervicalis found perivascular mononuclear dermatitis as the most consistent difference between the two groups. Seasonal variation in parasite numbers or cellular influxes was not observed. Eosinophilic dermatitis was observed in horses with onchocerciasis and dermatiti...

AIM The primary objective of the present study is to determine the commonness of filarial parasites in donkeys in Egypt, identification of the filarial species tainting them and the delivered pathogenic impact connected with the infestation. MATERIALS AND METHODS A total of 188 donkeys were examined for filarial infection. The blood samples and scraping of the cutaneous bleeding lesions were ...

OBJECTIVES/HYPOTHESIS To evaluate the long-term efficacy of contralateral ansa cervicalis-to-recurrent laryngeal nerve (RLN) anastomosis for unilateral vocal fold paralysis (UVFP), when the ansa cervicalis on the side of the paralyzed vocal fold was absent or there was any question about its viability. STUDY DESIGN We retrospectively reviewed 56 consecutive cases of delayed laryngeal reinnerv...

In recent years, there has been a proliferation of techniques utilizing the ansa cervicalis nerve to reinnervate the paralyzed larynx. The anatomic course and morphology of the ansa cervicalis are complicated by the variable course and location along the great vessels of the neck, as well as the significant differences observed in the arrangement of its contributing roots and regional branching...

Ansa cervicalis (ansa cervicalis profunda, ansa nervi hypoglossi) is one of the nerve connections in the human body. Two roots make up the ansa cervicalis –radix superior and radix inferior. Its sources include the ventral rami of the cervical spinal nerves; ansa innervates all infrahyoid muscles except for the thyrohyoid muscle [1,2]. In the past few years, there has been a development in the ...

With the expanding use of the ansa cervicalis nerve for laryngeal reinnervation procedures. So the aim of this work was to study the anatomical variations of ansa cervicalis in its roots, course and branching pattern. Twenty five Egyptian necks (50 sides) were dissected. The results showed that the ansa cervicalis (AC) consisted of two roots: superior and inferior roots. These two roots joined ...

Schwannomas are rare neoplasms that originate from Schwann cells. We present a case report of schwannoma of the ansa cervicalis in a patient where preoperative imaging suggested thyroid pathology. A 25-year-old man presented to the otolaryngology department with a one-year history of an asymptomatic, anterior triangle neck swelling. Imaging and FNA suggested a cystic lesion of the thyroid. Howe...

during the past few years, researchers and practitioners have developed novel techniques, using ansa cervicalis to innervate muscles of the larynx paralyzed due to surgical procedures carried out in the chest and neck areas. during routine dissection of a middle-age male cadaver, an unusual course of the superior root of the ansa cervicalis was observed. in this case, the superior root of the a...
