MATERIALS AND METHODS: This is a cross-sectional study where women aged between 20-80 years were recruited via convenient sampling from villages in Long Banga, Sarawak over a five-day outreach programme. Cervicovaginal selfsamples were obtained and screened for the presence of high-risk human papillomavirus DNA (HR-HPV) using the careHPVTM Test. A self-administered questionnaire was also administered to determine the sociodemographic and perception towards the self-sampling method.
RESULTS: The 55 women recruited consist of ethnic backgrounds of Penan (58.18%), Kenyah (25.45%), Iban (5.45%), Saban (3.64%), Kelabit (3.64%), Malay (1.82%) and Chinese (1.82%). The prevalence of HR-HPV was 1.85% (n=1/55). Nearly 80% of the women were unemployed, and more than half have had attended primary education. Nine (16.4%) have heard about HPV, and seven (13%) knew HPV infection could cause cervical cancer. Three of them had HPV vaccination, and only one (1.85%) knew the brand of the HPV vaccine. Although 40% preferred self-sampling over clinician-collection, only ten (18.2%) women have completed the self-collection perception questionnaire.
CONCLUSION: Primary HPV DNA screening using the selfsampling method can be carried out in the remote areas during the COVID-19 pandemic without compromising mobility restriction.
DESIGN: This was a prospective, randomized, observer-masked, crossover parallel comparison trial.
METHODS: Forty-one patients with primary open-angle glaucoma or ocular hypertension on nonfixed combination of latanoprost and timolol with IOP of 21 mm Hg or less were randomized to either bimatoprost-timolol or travoprost-timolol fixed combinations for 8-week treatment period. Intraocular pressure was measured at 8 AM, 12 PM, 4 PM, and 8 PM at the baseline and at the end point. Conjunctiva hyperemia and superficial punctate keratopathy after treatment with each fixed combination therapy were assessed and compared with the baseline. Patients were then switched to the opposite drug without a medication-free period for another 8-week, and diurnal IOP measurement was repeated.
RESULTS: Bimatoprost-timolol fixed combination reduced the baseline mean diurnal IOP statistically significantly from 17.3 mm Hg [95% confidence interval (CI), 16.8-17.7 mm Hg] to 16.4 mm Hg (95% CI, 15.9-17.0 mm Hg) (P = 0.036). Travoprost-timolol fixed combination lowered the mean diurnal IOP to 17.1 mm Hg (95% CI, 16.5-17.7 mm Hg), but it was not significant. Direct comparison between the 2 fixed combinations showed no significant difference. Both fixed combinations had no significant effect on conjunctiva hyperemia. Interestingly, patients on travoprost-timolol fixed combination had significantly less superficial punctuate keratopathy (P = 0.012).
CONCLUSIONS: Both fixed combination of bimatoprost-timolol and travoprost-timolol had no significantly different ocular hypotensive effect. However, bimatoprost-timolol fixed combination produced additional IOP lowering in patients previously treated with nonfixed combination of latanoprost and timolol.
METHODS: In a systematic study of the presentation and course of patients with acute P. knowlesi infection, clinical and laboratory data were collected from previously untreated, nonpregnant adults admitted to the hospital with polymerase chain reaction-confirmed acute malaria at Kapit Hospital (Sarawak, Malaysia) from July 2006 through February 2008.
RESULTS: Of 152 patients recruited, 107 (70%) had P. knowlesi infection, 24 (16%) had Plasmodium falciparum infection, and 21 (14%) had Plasmodium vivax. Patients with P. knowlesi infection presented with a nonspecific febrile illness, had a baseline median parasitemia value at hospital admission of 1387 parasites/microL (interquartile range, 6-222,570 parasites/microL), and all were thrombocytopenic at hospital admission or on the following day. Most (93.5%) of the patients with P. knowlesi infection had uncomplicated malaria that responded to chloroquine and primaquine treatment. Based on World Health Organization criteria for falciparum malaria, 7 patients with P. knowlesi infection (6.5%) had severe infections at hospital admission. The most frequent complication was respiratory distress, which was present at hospital admission in 4 patients and developed after admission in an additional 3 patients. P. knowlesi parasitemia at hospital admission was an independent determinant of respiratory distress, as were serum creatinine level, serum bilirubin, and platelet count at admission (p < .002 for each). Two patients with knowlesi malaria died, representing a case fatality rate of 1.8% (95% confidence interval, 0.2%-6.6%).
CONCLUSIONS: Knowlesi malaria causes a wide spectrum of disease. Most cases are uncomplicated and respond promptly to treatment, but approximately 1 in 10 patients develop potentially fatal complications.
