Gatifloxacin drops and an eye-patch over ointment were utilized post surgery and there were no complications (unfortunately, the patient did not return for DEC therapy to manage the additional worm—and microfilariae—present in his body). Epidemiology
As of 2009, loiasis is endemic to 11 countries, all in western or central Africa, and an estimated 12–13 million people have the disease. The highest incidence is seen in Cameroon, Republic of the Congo, Democratic Republic of Congo, Central African Republic, Nigeria, Gabon, and Equatorial Guinea. The rates of Loa loa infection are lower but it is still present in and Angola, Benin, Chad and Uganda. The disease was once endemic to the western African countries of Ghana, Guinea, Guinea Bissau, Ivory Coast and Mali but has since disappeared.Throughout Loa loa-endemic regions, infection rates vary from 9 to 70 percent of the population. Areas at high risk of severe adverse reactions to mass treatment (with Ivermectin) are at present determined by the prevalence in a population of >20% microfilaremia, which has been recently shown in eastern Cameroon (2007 study), for example, among other locales in the region.Endemicity is closely linked to the habitats of the two known human loiasis vectors, Chrysops dimidiata and C. silicea.Cases have been reported on occasion in the United States but are restricted to travelers who have returned from endemic regions.In the 1990s, the only method of determining Loa loa intensity was with microscopic examination of standardized blood smears, which is not practical in endemic regions.
A urethral caruncle is a benign cutaneous condition characterized by distal urethral lesions that are most commonly found in post-menopausal women. They appear red, and can be various sizes. They can have the appearance of a tumor. These epidermal growths are found around the posterior portion of the urethral meatus. They can bleed and occasionally cause dysuria and dyspareunia. The caruncles can be removed by surgery, electric cauterization and then with suture repair. Pathology studies are necessary to distinguish carcinoma of the urethra from urethral caruncles. Caruncles can grow back in some instances. Urethral caruncles can accompany the skin changes related to lowered estrogen levels. They can become a source of chronic hematuria, infection, and urethritis. See also
