ABSTRACT
One peek into the history of malaria, shows us that despite many attempts by mankind to counter the development and propagation of malaria, it has always risen back like a ‘phoenix from its ashes’. This has been possible by virtue of the singular ability of the malarial parasite to mutate and evade the actions of various anti-malarial drugs. The emergence of drug resistant malarial parasites by virtue of the various molecular mechanisms, has put the authorities under the cosh and forced the scientists to start generating newer and better anti-malarial drugs. In this review, we have dwelt upon the various molecular mechanisms which have allowed the malaria parasite to develop resistance, as it can serve to educate the scientists in their effort to generate newer anti-malarials.
ABSTRACT
Background: Drug-related problems are an important cause of morbidity and mortality and a significant burden on healthcare resources. There are few studies to account for errors in drug intake leading to adverse drug reactions (ADRs). This study was pursued with the objective of determining the frequency and severity of the ADRs resulting from erroneous drug intake, the expenses incurred in treating the same. Methods: The study was a prospective, cross-sectional, observational study. The study subjects were patients with ADRs due to errors in drug intake and from selfmedication. All the information regarding the ADR were collected as per ADR reporting form issued by Central Drugs Standard Control Organization. Causality was assessed by both Naranjo and the WHO criteria for causality assessment. Direct cost of all the medications, hospital charges (admission, bed charges, consultations paid, treatment charges, investigations, and conveyance charges) were recorded to find the financial burden due to error in drug intake. Results: The study showed that nearly 30% of the ADRs were due to errors in drug intake and the major contributing factor is self-modification either by discontinuation or missed doses. Major drugs that are implicated in these ADRs were that of metformin and insulins among anti-diabetic drugs and amlodipine and atenolol among antihypertensives. These two groups contributed to 18 (62%) of the total 29 ADRs. Organ system commonly involved was central nervous system and that was followed by musculoskeletal system. The average direct cost incurred in the management of these ADRs was Rs. 5773 for non-serious adverse events (SAE’s) and Rs. 11,400 for SAE’s. Conclusion: Proper education about the importance of compliance and damaging consequences of self-modification of drug dosage in patients who are on treatment for chronic disorders like diabetes and hypertension will be an effective strategy to prevent many of these ADRs.

ABSTRACT
Background: Prevention and control of AIDS are now a major problem as there is no vaccine or effective-curative treatment for this disease. Health care workers (HCWs) are at increased risk for HIV infection. There were inadequate studies about post-exposure prophylaxis (PEP) of HIV among HCWs in southern India. Hence, we are conducting this study to assess the attitude and practice of PEP toward HIV among HCWs. Methods: The cross-sectional study was done among HCWs (doctors, surgeons, nurses, and dentists). Pre-tested questionnaire was given and requested to fill it after explaining the purpose of the study. About 65% and above correct answers was considered as adequate response. Values expressed as mean, proportions and analyzed by SPSS version 17. Results: Overall 6 (66%) of the total 9 questions in attitude were answered satisfactorily, and thus can be said to have good attitude regarding PEP in HIV. Only 16 people (10%) of the participants had taken PEP regimen. Among those who took PEP, the responses for the questions about the time of initiation of regimen, completion of prescribed duration of therapy and checking of HIV status after completion of regimen were unsatisfactory. Among the professions, surgeons were exposed more compared to other professions. Conclusion: Overall attitude toward PEP was positive among all the HCWs. The practice of PEP was not satisfactory even after exposure to risks. Informing HCWs about completing treatment course and post-treatment testing is important to prevent HIV transmission. Awareness of PEP should be improved among health professionals, by regular training meetings and introducing the guidelines of the safe practices in the academic syllabus of all the professions.
ABSTRACT
Improved antioxidant status helps to minimize the oxidative damage and thus can delay the risk of developing many chronic age related, free radical induced damage in diseases like diabetes, cancer, neurodegenerative diseases. We tried to evaluate the antioxidant potential of Costus igneus (CI) leaves in ethanol induced peroxidative damage in albino rats. Wistar albino rats of either sex were divided into four groups. Group I was control group and received normal saline, Group II received ethanol, Group III received test drug CI at 300 mg/kg and Group IV received CI at dose of 600 mg/kg. Study duration was 30 days. Antioxidants estimated at the end of 30 days. The levels of reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) significantly reduced and (malondialdehyde) MDA levels raised in ethanol treated group compared to control group. The levels of reduced glutathione, SOD and catalase enzyme recovered completely in a dose dependent manner. Results demonstrate CI significantly reversed the reduction of GSH, SOD and CAT and reduced significantly the levels of MDA, a biomarker of lipid peroxidation in a dose dependent manner, suggesting its ability to enhance the antioxidant defense to prevent alcohol induced oxidative stress injury.
