Anesthetic potential of lidocaine/prilocaine cream versus placebo before venepuncture

Background: Pain associated with venepuncture has long been accepted as an unavoidable consequence. Many studies show reducing pain during venepuncture after application of prilocaine/lignocaine, but there are few studies that has depicted, the depth of anesthesia produced by prilocaine/lignocaine tends to be too superficial for the reducing the pain during venepuncture. These two scenarios were debatable. Therefore, authors planned a study to assess anesthetic potential of lidocaine /prilocaine cream versus placebo before venepuncture with help of VAS in an adult patient who were drawn blood sample for investigation purposes.Methods: Prospective interventional study. All adult patient for blood sampling from surgery OPD to central laboratory were included in study. Site of venepuncture selected in both control and study group was left cubital fossa. 30 patients selected in study group received lignocaine/prilocaine locally, 30min prior to venepuncture which was later covered with occlusive tape, whereas 30 control group patient received normal saline locally as placebo. The extent of pain was assessed by patient on 10cm visual analogue scale (VAS) with end points of 0 cm rated as no pain and the points of 10cm as intolerable pain.Results: A total of 60 patient were randomly selected who were referred from surgery OPD for blood sampling. Other 30 patient were applied normal saline as placebo and 30 patient with lignocaine and prilocaine cream. In the control group there were 30 patients (5 female and 25 male). In the study group there were 30 patients (8 females and 22 males). The level of pain among study group is as follows: mild 22, moderate 7, worst 1 and in control group: no pain 0, mild 5, moderate 14 and worst pain 1. Statistical analysis between outcome of two groups done by calculating chi-square test. Chi- square test was 20.0263. P value is 0.000168. Hence the result is significant at p <0.05.Conclusions: The present study shows that prilocaine-lidocaine cream reduces the pain of needle puncture in adults and facilitates the procedure of venous blood sampling

Drug utilization pattern of antimicrobials use in upper respiratory tract infection in paediatric patient of rural tertiary care hospital

Background: Antimicrobial agents (AMAs) are most commonly prescribed drugs for lower respiratory tract infection (LRTI). This study was conducted to evaluate pattern of prescription and AMAs use in paediatric patient for LRTI in wards of rural tertiary care teaching hospital.Methods: This is prospective, observational study undertaken in paediatric patient in tertiary care hospital. Prescriptions of 60 patient of age group 1-12years diagnosed with LRTI admitted in paediatric ward of rural tertiary care teaching hospital were studied. Positive blood sample were studied for common microorganisms, their sensitivity and resistance to AMAs.Results: Out of 60 patients admitted in paediatric ward of LRTI, 12 patients were of mild to moderate pneumonia, three patients were of bronchiolitis, ten patients were of croups, three patients were of bronchitis and 37 patients were of severe pneumonia. The most frequently prescribed AMAs were combination of cephalosporin and aminoglycosides. The most common organism isolated was streptococcus pneumoniae sensitive to vancomycin in 92.3% and meropenem in 84.6%, resistant to ampicillin, amoxicillin and cloxacillin in 92.3% of cases.Conclusions: The study shows utilisation pattern of AMAs in LRTI, prescribing on which future intervention studies may be based to promote rational drug use

ANALISIS DAMPAK NEGATIF DAN SOLUSI PENYELESAIANNYA TERHADAP KEGIATAN PENAMBANGAN EMAS TANPA IZIN PADA KAWASAN BUKIT NAGA : ANALYSIS OF NEGATIVE IMPACT AND ITS SOLUTIONS ON UNLIMITED GOLD MINING ACTIVITIES IN THE BUKIT NAGA AREA

The Bukit Naga area is an area that has recently attracted the attention of the wider community, because it is alleged to have quite large gold potential.  People flocked to the area to carry out gold mining activities. In order to get an overview of the impacts arising from gold mining activities in the Bukit Naga area, research was carried out on the influence of gold mining activities on the socio-cultural conditions of the community and their environmental conditions, as well as solutions to solving the problems encountered.  The research was conducted using the literature study method for data collection.  Data analysis used descriptive-qualitative method.  The results of the study describe that gold mining activities carried out in the Bukit Naga area have an impact on the socio-cultural conditions of the community (security, health, conflicts of interest in doing business, and local community culture) and environmental conditions (changes in the bio-physical environment, disruption of the ecosystem, reduced and loss of flora and fauna, occurrence of erosion, landslides and floods, as well as environmental pollution). From a legal perspective, the mining activities carried out are illegal activities, which are contrary to and violate the applicable laws and regulations. Problem solving solutions offered: conduct preventive law enforcement, proposing the Bukit Naga area to become a WPR facilitate recommendation and licensing of gold mining business, equipping the community with good and environmentally friendly mining activities and good coordination and collaboration of all parties in managing and utilizing the Bukit Naga gold mining area.  Keywords: Bukit Naga Area, Gunung Mas Regency, Gold Mine

Tetra-μ-aqua-octaaqua­bis(μ-4-chloro­pyridine-2,6-dicarboxyl­ato)bis­(4-chloro­pyridine-2,6-dicarboxyl­ato)tri­cobalt(II)disodium(I) bis­[triaqua­bis(4-chloro­pyridine-2,6-dicarboxyl­ato)cobalt(II)] hexa­hydrate

The title compound, [Co3Na2(C7H2ClNO4)4(H2O)12][Co(C7H2ClNO4)(H2O)3]2·6H2O, consists of a centrosymmetric dimer of [CoII(dipicCl)2]2− complex dianions [dipicCl is 4-chloro­pyridine-2,6-dicarboxyl­ate] bridged by an [Na2CoII(H2O)12]4+ tetra­cationic cluster, two independent [Co(dipicCl)(H2O)3] complexes, and six water mol­ecules of crystallization. The metals are all six-coordinate with distorted octahedral geometries. The [CoII(dipicCl)(H2O)3] complexes are neutral, with one tridentate ligand and three water molecules. The [CoII(dipicCl)2]2− complexes each have two tridentate ligands. The [Na2CoII(H2O)12]4+ cluster has a central CoII ion which is coordinated to six water molecules and lies on a crystallographic inversion center. Four of the water molecules bridge to two sodium ions, each of which have three other water molecules coordinated along with an O atom from the [CoII(dipicCl)2]2− complex. In the crystal structure, the various units are linked by O—H⋯O hydrogen bonds, forming a three-dimensional network. Two water molecules are disordered equally over two positions

Biofunctionalization of zinc oxide nanowires for DNA sensory applications

We report on the biofunctionalization of zinc oxide nanowires for the attachment of DNA target molecules on the nanowire surface. With the organosilane glycidyloxypropyltrimethoxysilane acting as a bifunctional linker, amino-modified capture molecule oligonucleotides have been immobilized on the nanowire surface. The dye-marked DNA molecules were detected via fluorescence microscopy, and our results reveal a successful attachment of DNA capture molecules onto the nanowire surface. The electrical field effect induced by the negatively charged attached DNA molecules should be able to control the electrical properties of the nanowires and gives way to a ZnO nanowire-based biosensing device

Speciation, Luminescence, and Alkaline Fluorescence Quenching of 4-(2-methylbutyl)aminodipicolinic acid (H2MEBADPA)

4-(2-Methylbutyl)aminodipicolinic acid (H2MEBADPA) has been synthesized and fully characterized in terms of aqueous phase protonation constants (pKa\u27s) and photophysical measurements. The pKa\u27s were determined by spectrophotometric titrations, utilizing a fully sealed titration system. Photophysical measurements consisted of room temperature fluorescence and frozen solution phosphorescence as well as quantum yield determinations at various pH, which showed that only fully deprotonated MEBADPA2– is appreciably emissive. The fluorescence of MEBADPA2– has been determined to be quenched by hydroxide and methoxide anions, most likely through base-catalyzed excited-state tautomerism or proton transfer. This quenching phenomenon has been quantitatively explored through steady-state and time-resolved fluorescence measurements. Utilizing the determined pKas and quenching constants, the fluorescent intensity of MEBADPA2– has been successfully modeled as a function of pH
