We studied 424 adults with falciparum malaria admitted over 28 months. They were divided into three groups: cerebral malaria (n = 214); severe non-cerebral malaria (n = 58); and uncomplicated malaria (n = 152). Fundus examination was done daily from admission to discharge, and weekly thereafter in those with persistent changes. All patients were treated by a protocol based on WHO guidelines. Ophthalmoscopic abnormalities were: retinal haemorrhages, 40 (9.43%) (25 cerebral malaria, 10 severe non-cerebral and five uncomplicated malaria); papilloedema, 17 (7.94%) cerebral malaria and two uncomplicated malaria; blurring of disc margins, 25 (11.68%) cerebral and seven non-cerebral; retinal oedema, six (2.80%) cerebral and five non-cerebral malaria; disc pallor, five patients all with cerebral malaria; vitreous haemorrhage and hard exudate in one patient each, both cerebral malaria. Retinal haemorrhage was associated with cerebral malaria and severe non-cerebral malaria, especially with severe anaemia (p < 0.001), as compared to uncomplicated malaria (p < 0.01). The association of papilloedema and cerebral malaria was highly significant compared to severe non-cerebral malaria (p < 0.001). None of these findings was associated with statistically significant mortality, except disc pallor in cerebral malaria (p < 0.05).
Malaria is one of the major infectious diseases that remains a constant challenge to human being mainly due to the emergence of drug-resistant strains of parasite and also the availability of drugs, which are non-specific for their pharmacodynamic activity and known to be associated with multiple side effects. The disease has acquired endemic proportions in tropical countries where the hygienic conditions are not satisfactory while the environmental conditions favor the proliferation of parasite and its transmission, particularly through the female anopheles. It is obvious that to square up the problems, there is a need for designing and development of more effective drugs, which can combat the drug-resistant strains of the parasite. Molecular biology of the parasite and its homing into host cellular tropics provide multiple drug targets that could judiciously be considered for engineering and designing of new generation antimalarial drugs and also drug delivery systems. Though the recent reports document that against malaria parasite the vaccine could be developed, nevertheless, due to smart mutational change overs by the parasite, it is able to bypass the immune surveillance. The developed vaccine therefore failed to assure absolute protection against the malarial infection. In the conventional mode of treatment antimalarial drugs, the dose and dosage regimen that is followed at large crops up the contraindicative manifestations, and hence compromising the effective treatment. The emerging trends and new updates in contemporary biological sciences, material sciences, and drug delivery domain have enabled us with the availability of a multitude of mode and modules which could plunge upon the nanotechnology in particular to treat this challenging infection. The nanotechnology-based option may be tuned or customized as per the requirements to mark and target i.e. the infected RBCs, for targeted drug delivery.
Purpose:The aim of the study was to present the level of knowledge and practice patterns regarding exposure keratopathy in mechanically ventilated patients among Intensive Care Unit (ICU) nurses in Chhattisgarh state.Methods:A previously validated semi-structured questionnaire was administered in the ICU of six multispecialty hospitals in Chhattisgarh in 2014–2015. Demography included age, gender, level of education, and months of working in ICU. Most of the questions dealt with frequency of eyelid closure assessment, frequency of cleaning of eyes with saline gauze, using a protocol-based approach for eye care, and documentation of ophthalmic complications. Common barriers to delivery of eye care such as shortage of time and too much writing tasks were also inquired.Results:Our study included 120 nurses. They worked for mean 22.9 ± 17.8 months in ICU. Knowledge about high risk of exposure keratopathy in ventilated patient was present in 93% (78%; 95% confidence interval [CI]) nurses. Only six nurses (5%) followed a strict protocol for eye care, 52 nurses (43%) checked for eyelid closure in the ventilated patients, and 58 (48%) cleaned the eyes frequently. Those who were aware of exposure keratopathy checked eyelid closure (73% vs. 48%) and cleaned eyes with saline gauze more frequently (24% vs. 4%). Nurses in cardiac ICU were significantly lesser aware of exposure complications compared to medical ICU nurses (40% reduction in awareness, 95% CI = 0.37–0.98, P = 0.04).Conclusion:Although there is high awareness, practice patterns of ICU nurses were less than desired. Educational initiatives should focus on weaknesses in knowledge and practice noted to improve eye care of patients in ICU.
