ABSTRACT

Acanthamoeba keratitis is a rare but severe corneal infection which, despite improvements in diagnosis and treatment, still culminates in prolonged morbidity and significant loss of visual acuity. We present the case report of the first identification of Acanthamoeba as a causative agent of keratitis in Tunisia. Case no 1: A 20-year-old girl, nearsighted corrected with soft contact lenses, suffering from a deep corneal inflammation and poor visual acuity The ophthalmological examination showed bilateral dendritiform epithelial keratitis. The illness did not respond to topical and general antibiotic treatment and developed bilateral corneal abscess. Microscopic examination and culture of samples from cornea scraping revealed the presence of trophozoit and cysts of Acanthamoeba associated with Fusarium oxysporum. As the treatment with local Ketoconazol and antibiotherapy didn't show any result, two transfixiant keratoplasty were carried out and treatment by Désomédine, PHMB (polyhexamethylene biguanide) and Voriconazol was started. After two months, the patient felt better, vision was also improved (2/10) and infiltrates became smaller Case no 2: A 19-year-old girl, nearsighted with soft contact lenses consulted for a bilateral corneal ulceration and poor vision (1/20). Trophozoit and cysts of Acanthamoeba were found in the contact lens solution. She was treated quickly with Désomédine. Visual acuity improved to 7/10 but the corneal ulceration left a residual opacity

ABSTRACT

Observations were made of 996 encounters between children with diarrhoea and practitioners (28 paediatricians, 62 general practitioners) in Karachi, Pakistan. Oral rehydration salt (ORS) was prescribed in more than 50% of encounters by 53% of general practitioners (GPs) and 61% of paediatricians. Sixty-six percent of GPs and 50% of paediatricians prescribed antibacterials, 60% of GPs and 28% of paediatricians prescribed antidiarrhoeals and 39% of GPs and 32% of paediatricians prescribed antiamoebics in more than 30% of their encounters. Looking at all the encounters, we observed that ORS was prescribed in 52 and 51%, antibacterials in 41 and 36%, antidiarrhoeals in 48 and 29%, and antiamoebics in 26 and 22% of encounters by GPs and paediatricians, respectively, Cotrimoxazole was the most frequently prescribed antibacterial by both types of practitioners. Antidiarrhoeals were prescribed more often by GPs than by paediatricians. In 77% of their encounters, GPs dispensed drug formulations known as "mixtures' made in their own dispensing corners. The mean duration of encounters between patients and GPs was 3 +/- 2 minutes and between patients and paediatricians was 9 +/- 4 minutes. These results indicate inadequate prescription of ORS and excessive prescription of antibacterials, antidiarrhoeals and antiamoebics. Intervention strategies need to be planned to improve the prescribing practices of both groups.
