Neonatal septicemia is one of the leading causes of neonatal mortality and morbidity worldwide. Hence, the present study was undertaken to isolate the bacteria causing neonatal sepsis and determine their antibiotic susceptibility pattern. Fifty neonates suspected to have septicemia were screened for 2 months (July and August 2014). Out of 50 specimen, 15 (30%) were blood culture positive. Coagulase-negative staphylococci was the most common isolate (10, 66.6%), with 60% (6 isolates) methicillin resistance. In view of the increasing antibiotic resistance, periodic surveillance should be conducted to control the emergence and spread of antimicrobial resistance.
Aims and Objectives Mupirocin is a widely used topical antibiotic for the treatment of skin and soft tissue infections. This has resulted in resistance leading to treatment failure. Hence, the present study aimed to determine the prevalence of mupirocin resistance among staphylococcal isolates obtained from the skin and soft tissue infections. Also, comparison of disc diffusion and agar dilution method in detecting mupirocin resistance was done.
Materials and Methods This cross-sectional study was conducted in the Department of Microbiology of a tertiary health care center in Karnataka from January to December, 2018. Clinical samples such as wound swabs, tissues, and pus were included in the study. All staphylococcal isolates were screened for mupirocin resistance using 5 µg and 200 µg discs for low-level (MuL) and high-level mupirocin resistance (MuH), respectively. Minimum inhibitory concentration (MIC) was determined using the agar dilution method.
Results Out of 100 staphylococcal isolates, 68 were Staphylococcus aureus and 32 were CoNS. MuH was detected in 11 isolates. MuH was more common in CoNS (10/11) compared with S. aureus (1/11). MuL was not found in the study.
Discussion In our study, 10 out of 11 mupirocin-resistant isolates were methicillin resistant, which is statistically significant (p < 0.05). The correlation between results of disc diffusion and MIC were appropriate in this study.
Conclusion Judicial prescription of mupirocin after knowing the susceptibility report should become the standard practice. Screening for mupirocin resistance can be done by disc diffusion in resource-limited settings.
Introduction: The emergence of Methicillin Resistant (MR) staphylococcal infections had led to fewer therapeutic options. Ceftaroline fosamil is the only cephalosporin approved by United States of America (USA) Food and Drug Administration (FDA) till now which has activity against MR staphylococcal isolates. Until now, studies on in-vitro activity of ceftaroline are limited. Aim: To know the susceptibility pattern of Methicillin Resistant Staphylococcus aureus (MRSA) and Methicillin Resistant Coagulase Negative Staphylococci (MRCoNS) against ceftaroline in a rural tertiary health care centre. Materials and Methods: The present cross-sectional study was conducted in a tertiary care hospital in rural part of Karnataka between two months (July and August 2019). A total of 50 consecutive, non repetitive clinical isolates of MRSA and MRCoNS were obtained. Antibiotic susceptibility testing was done according to Clinical and Laboratory Standards Institute (CLSI) guidelines. The Minimum Inhibitory Concentration (MIC) of ceftaroline was detected using E-strips (Biomerieux). The CLSI breakpoints applied for the interpretation of ceftaroline MIC- Sensitive: ≤1 μg/mL; Susceptible Dose Dependent (SDD): 2-4 μg/ mL and resistant ≥8 μg/mL). Staphylococcus aureus American Type Culture Collection (ATCC) 29213 was used as a quality control. Statistical analysis was done using microsoft excel. Percentages were used in this study to analyse variables. Results: Out of 50 MR staphylococcal isolates, 10 (20%) were MRSA and 40 (80%) were MRCoNS. Of the MR staphylococcal isolates tested, 49 (98%) were sensitive to ceftaroline. The MIC 50 and MIC 90 for the 50 MR staphylococci was 0.25 μg/mL and 1 μg/mL, respectively. Conclusion: Ceftaroline demonstrated a potent in-vitro activity against MR staphylococci. So it can be used as an effective drug in the treatment of such infections.
INTRODUCTIONAsthma is derived from the Greek word meaning "to stay in order to breathe or difficulty in breathing".1 Bronchial asthma is a condition of the lungs characterized by widespread narrowing of the airways due to spasm of the smooth muscle, edema of the mucosa, and the presence of mucus in the lumen of the bronchi and bronchioles. It is caused by the local release of spasmogens and vasoactive substances in the course of an allergic reaction.2 According to World Health Organization (WHO-2010) 300 million people worldwide were affected by asthma leading to approximately 250,000 deaths per year.3 It is the most common chronic illness in childhood and is one of the most common causes of admission to the hospital among children and adults.
4Salbutamol is a fairly selective beta-2 agonist with relaxant effects on smooth muscles of bronchi and uterus. Being a non-catecholamine it is not metabolized by COMT and thus exhibits longer duration of action than isoprenaline. For immediate relief of asthma it is given by oral inhalation from a metered dose inhaler, 100 micro grams in a single dose. It can also be given orally, intra muscularly or by slow I.V injection. Sustained release tablets are also available. Inhalation causes fewer side effects than systemic administration. Tiotropium bromide has longer duration of action and shows some selectivity ABSTRACT Background: The objective of this study was to compare the safety and efficacy of tiotropium bromide with salbutamol in moderate persistent cases of bronchial asthma at tertiary care hospital.
Methods:This was an open label, randomized parallel group study done in Government General Hospital, Srikakulam for a period of 12 weeks. Group-1 was given tiotropium bromide metered dose inhalational therapy 18mcg once daily in 50 patients. Group-2 was given salbutamol metered dose inhalational therapy 100mcg thrice daily in 30 patients. Results: Symptomatic improvement was observed in l two groups. At end point, mean FEV1 in tiotropium bromide treatment group improved by 149.96% compared with 135.16% salbutamol treatment group. At end point, mean FVC value in tiotropium bromide treatment group improved by 145.71% compared with 122.34% in salbutamol group. Mean FEV 1 / FVC also improved by 155.41% in tiotropium bromide group compared with 105.41 % in salbutamol group.
Conclusion:The present study proved tiotropium provide superior safety and efficacy relative to control drug in bronchial asthma patients in both clinical assessment score and spirometrically.
