  • “Ceftriaxone– Sulbactam–EDTA” and Various Antibiotics Against Gram
    ORIGINAL ARTICLE A Comparative In Vitro Sensitivity Study of “Ceftriaxone– Sulbactam–EDTA” and Various Antibiotics against Gram- negative Bacterial Isolates from Intensive Care Unit Sweta Singh1, Chinmoy Sahu2, Sangram Singh Patel3, Abhay Singh4, Nidhi Yaduvanshi5 ABSTRACT Introduction: A rapid increase in multidrug-resistant (MDR) strains is being seen across the globe especially in the Southeast Asian region, including India. Carbapenems and colistin form the mainstay of treatment against gram-negative pathogens, especially extended-spectrum beta-lactamase (ESBL)- and metallo-beta-lactamse (MBL)-producing isolates. However, due to increased resistance to carbapenems and toxicity of colistin, especially in intensive care units (ICUs), carbapenem-sparing antibiotics like ceftriaxone–sulbactam–EDTA (CSE) combination needs to be evaluated. Materials and methods: Bacterial isolates cultured from various clinical samples from all ICUs for a period of 9 months were evaluated. Bacterial identification was performed by matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) and antibiotic susceptibility testing were performed by disk diffusion and E test method. Antibiogram of various antibiotics was noted. Extended-spectrum beta-lactamase- and MBL-producing bacteria were identified by phenotypic methods. Antibiotic sensitivity results of CSE were compared with the comparator drugs like colistin, carbapenems, and tigecycline in Enterobacteriaceae, Acinetobacter spp., and Pseudomonas spp. along with ESBL and MBL producers. Results: A total of 2,760 samples of blood, cerebrospinal fluid (CSF), respiratory samples, tissue, and pus were collected from ICUs with maximum isolates from pus (37%) followed by respiratory samples (31%) and blood (27%). Escherichia coli and Klebsiella pneumoniae were the predominant gram-negative pathogens accounting for 56% of the isolates followed by Acinetobacter spp.

  • Suprapubic Puncture in the Treatment of Neurogenic Bladder
    SUPRAPUBIC PUNCTURE IN THE TREATMENT OF NEUROGENIC BLADDER CHARLES C. HIGGINS, M.D. W. JAMES GARDNER, M.D. WM. A. NOSIK, M.D. The treatment of "cord bladder", a disturbance of bladder function from disease or trauma of the spinal cord, can be a difficult problem. Until the recent publications of Munro, there was little physiological basis for whatever treatment was instituted. With the advent of tidal drainage and recognition of the various types or stages of a given cord bladder, more satisfactory results have been obtained. In his excellent work on the cystometry of the bladder Munro1,2 classifies "cord bladders" into four groups: 1. Atonic — characterized by retention and extreme distention from lack of detrusor tone, lack of any activity of the external urethral sphincter, and complete lack of emptying contractions. 2. Autonomous — the detrusor and internal sphincter musculature show signs of reciprocal action of varying degree. There is an increase in detrusor muscle tone, and an inability to store an appreciable amount of urine without leakage. The condition of this bladder represents the end result in destructive lesions of the sacral segments or cauda equina. 3. Hypertonic — an expression of an uncontrolled spinal segmental reflex, characterized by a markedly increased detrusor muscle tone, almost constantly present emptying contractions, low residual urine, and impairment of control of the external sphincter. 4. Normal cord bladders — in transecting lesions above the sacral segments, consisting of two types which differ largely only in their cystometric findings: (a) Uninhibited cord bladder — an apparently normal bladder which empties itself quite regularly. The detrusor tone is still somewhat increased, emptying contractions are rhythmical, the residual is low, and the capacity is rather low.

  • Simultaneous Determination of Amoxicillin and Clavulanic Acid in Pharmaceutical Preparations by Capillary Zone Electrophoresis
    Brazilian Journal of Pharmaceutical Sciences vol. 52, n. 2, apr./jun., 2016 Article http://dx.doi.org/10.1590/S1984-82502016000200006 Simultaneous determination of amoxicillin and clavulanic acid in pharmaceutical preparations by capillary zone electrophoresis Gabriel Hancu1,*, Anamaria Neacşu1, Lajos Attila Papp1, Adriana Ciurba2 1Department of Pharmaceutical Chemistry, Faculty of Pharmacy, University of Medicine and Pharmacy, TîrguMureş, Romania, 2Department of PharmaceuticalTechnology, Faculty of Pharmacy, University of Medicine and Pharmacy, Tîrgu Mureş, Romania Clavulanic acid enhances the antibacterial spectrum of amoxicillin by rendering most β-lactamase producing isolates susceptible to the drug. A fast, simple and efficient capillary electrophoresis method was developed for the simultaneous determination of amoxicillin and clavulanic acid from complex mixtures. Using a 25 mM sodium tetraborate as background electrolyte at a pH of 9.30, + 25 kV applied voltage, 25 °C system temperature, UV determination at 230 nm; we succeeded in simultaneous separation of amoxicillin and clavulanic acid in approximately 2 minutes. The analytical performance of the method was evaluated in terms of reproducibility, precision, accuracy, and linearity. The optimized analytical method was applied for the determination of the two analytes from combined commercial pharmaceutical preparations. This CE method is fast, inexpensive, efficient, and environmentally friendly when compared with the more frequently used high performance liquid chromatography methods described in the literature. Uniterms: Amoxicillin/determination. Clavulanic acid/determination. Capillary electrophoresis/ quantitative analysis. Antibacterials/quantitative analysis. O ácido clavulânico acentua o espectro antibacteriano de amoxicilina, tornando a maioria dos isolados produtores de β-lactamase sensíveis ao fármaco. Desenvolveu-se um método rápido, simples e eficiente de electroforese capilar (EC) para a determinação simultânea de amoxicilina e de ácido clavulânico a partir de misturas complexas.
