[What about tropical endemic vernal keratoconjunctivitis? Which relationship with intestinal parasites?] / Que savons-nous de la limboconjonctivite endémique des tropiques ? Et quel rapport avec les parasites intestinaux ?

Given the causative parasite hypothesis for tropical endemic limbo-conjunctivitis (TELC), we conducted an analytical case-control study of all children with tropical endemic limbo-conjunctivitis seen in the ophthalmology department of Laquintinie hospital in Douala during the period from January 2nd to April 30, 2015. RESULTS: We identified 64 cases of tropical endemic limbo-conjunctivitis out of 550 children seen; a hospital prevalence of 11.6%; thirteen cases (eight boys and five girls) did not meet inclusion criteria, and 51 cases were included, 31 boys (60.8%) and 20 girls (39.2%) with a male/female (M/F) sex-ratio of 1.41. For controls, we included 28 males (54.9%) and 23 girls (45.1%) for a M/F sex-ratio of 1.22. The prevalence of tropical endemic limbo-conjunctivitis in boys was 12.1%, and for girls it was 7.1% in the case group. Stage II was the most frequent at 29 cases (56.9%), as well as the mixed form at 31 cases (60.8%). The frequency of intestinal parasites was 14 cases (27.5%) in the group of tropical endemic limbo-conjunctivitis patients and 6 cases (11.8%) in the control group (P=0.08). Entamoeba histolytica in its cystic form was the most intestinal parasite found in both groups, 10 cases for tropical endemic limbo-conjunctivitis (19.6%) and 6 cases in the control groups (11.8%). The mean serum IgE among cases was 81.2 IU/ml, while in the controls it was 15.6 IU/ml (P=0.001) CONCLUSION: There is no relationship between intestinal parasitic infection and the occurrence of tropical endemic limbo-conjunctivitis.

[The problem of oculo-orbital trauma due to motor vehicle accidents involving commercial motorbikes in Douala, Cameroon]. / Les traumatismes oculo-orbitaires dus aux accidents de motos taxis à Douala au Cameroun.

UNLABELLED: A prospective and longitudinal study was carried from January 2 to December 31, 2013 in which victims of commercial motor bike accidents presenting to the Laquintinie Hospital in Douala were examined in search of oculo-orbital injuries with the double goal of identifying and evaluating the physical impact of the observed oculo-orbital lesions. RESULTS: We included 88 cases with oculo-orbital trauma due to commercial motor bike accident. There were 71 males (80.7%) and 17 females (19.3%). The mean age was 32.8±10.6 years. Collision between two motorbikes was the most frequent mechanism and accounted for 42% of cases of oculo-orbital trauma (n=37). None of the 81 patients on a motor bike reported wearing a helmet at the time of the accident (7 pedestrians were victims). Injuries of the globe were present in 16.5% of eyes (n=29); while orbital injuries were present in 22% of eyes (n=39). The most frequent orbital injury was orbital wall fracture, occurring in 31 eyes (17.6%). Lesions of the eyelids were found in 50 cases (28.4%). ENT lesions were associated in 27 cases (30.7%), cranial trauma in 3 cases (3.4%). Orbital dystopia, oculomotor palsy, ptosis, ectropion and unilateral blindness (rate of 9%) were sequelae recorded after six months of follow-up. CONCLUSION: The existing rules and regulations on driving licenses, vehicle code and compulsory use of helmets in the area of commercial motorbike activity should be strictly applied in Douala to avoid these preventable oculo-orbital trauma which lead to unsightly scars and blindness.
