Phenotypic Time Trend in Performance Evaluation of Dahlem Red Chicken under Intensive Management in Himachal Pradesh

A study was conducted to evaluate the production performance of Dahlem Red chicken over three consecutive generations maintained in intensive system. Dahlem Red birds were initially procured from CPDO Chandigarh and further produced through selective breeding. Performance traits evaluated were growth (day old chick weight, 4th week body weight (BW), 8th week BW, 12th week BW, 20th week BW and 40th week BW), age at sexual maturity, hen housed egg production (HHEP), hen day egg production (HDEP) and survivor egg production (SEP) at 40, 52 and 72 weeks of age and egg weight at 28, 40 and 52 weeks of age. Analysis revealed positive phenotypic trend in 4 week (17.58 g), 8 week (56.35 g), 12 week body weight (133.5 g), age at first egg (5.5 days) and age at 25% HHEP (2.0 days). The hen housed and hen day egg production at 40, 52 and 72 weeks revealed positive phenotypic trend of 4.79 and 1.93, 15.83 and 8.31, 31.6 and 13.98 eggs respectively. Further, survivor egg production also showed positive trend estimates at 40 and 52 weeks. Declining trends were observed in SEP at 72 week, day old chick weight (-0.89 g), 20 week BW (-37.99 g), 40 week BW (-141.2 g) and egg weight at 28 week (-1.7 g), 40 week (-3.3 g) and 52 week (-2.3 g). The results indicated the effectiveness of the selection along with improved management for bringing improvement in production traits in successive generations

Protocol for developing a surveillance system for surgical site infections

Purpose: Healthcare-associated infections (HCAIs/ HAIs) are the most common adverse occurrences during health care delivery. Across the globe, millions of patients are affected by HAIs annually, with a higher burden and impact in developing nations. a major lacuna in planning preventing protocols is the absence of National Surveillance Systems in most low-middle income countries, which also prevents allocation of resources to the high-priority areas. Among all the HAIs, there is a huge global burden of SSIs, in terms of morbidity, prolonged hospital stays, increased antimicrobial treatment as well as attributable mortality. Method: This manuscript details the process of establishment of an SSI surveillance protocol at a level-1 trauma centre in North India. Result and Conclusion: Surveillance is an essential tool to reduce this burden. It is also an important primary step in recognizing problems and priorities, and it plays a crucial role in identifying risk factors for SSI and to be able to target modifiable risk factors. Therefore, it is imperative to establish reliable systems for surveillance of HAIs, to regularly estimate the actual burden of HAIs, and to use these data for developing indigenous preventive measures, tailored to the country's priorities.

Bilateral absence of inferior thyroid artery: A rare variation

Background: There are reports regarding the origin of the inferior thyroid artery from the vertebral artery and internal thoracic artery. The absence of inferior thyroid artery has been reported in studies, but most of these studies have reported the unilateral absence of inferior thyroid artery. Objective: The objective of the study was to identify and variations in origin (especially presence or absence of artery) and branches of inferior thyroid artery. Materials and Methods: A total of 96 cadavers were dissected and observed for origin and branching pattern of inferior thyroid artery. Results: Inferior thyroid artery originated from thyrocervical trunk in 94 cadavers, in one cadaver there are bilateral absence of inferior thyroid artery and in one case unilateral absence of Rt. inferior thyroid artery. Multiple variations of relations of recurrent laryngeal nerve and inferior thyroid artery are found. Conclusion: Knowledge of arterial variation is extremely important while carrying out surgical procedures in the neck region. During operations of the thyroid gland, surgeries of neck region, carotid angiographies any misinterpretation can lead to life-threatening complications. This study is not only focusing on the presence of different branching pattern but also the absence of major arteries. Studies like these can help surgeons to look closely for variations in both cases either presence or absence of main arteries.

Pathogen burden & associated antibiogram of Pseudomonas spp. in a tertiary care hospital of India

Antimicrobial resistance particularly in Gram-negative bacilli is an increasing problem worldwide. Pseudomonas spp. is one the most common Gram-negative bacteria associated with nosocomial infections and therefore, its trend of antimicrobial resistance needs to be studied. The aim of this study was to evaluate the rate of antimicrobial resistance and changes in resistance pattern over a period of five years (2012-2016) in Pseudomonas spp. isolated from trauma patients attending a tertiary care hospital in north India. During the study, a total of 2444 Pseudomonas spp. were isolated from the various clinical sample. The most common species isolated was P. aeruginosa (2331, 95%). The highest level of resistance was observed against levofloxacin (1678, 69%) and the lowest level of resistance was observed against tobramycin (1254, 51%). Irrational and inappropriate use of antibiotics was found to be responsible for multidrug resistance in Pseudomonas spp. Hence, there is an urgent need to emphasize strict antibiotic policy to minimize the misuse of antimicrobials.

Antimicrobial resistance in beta-haemolytic streptococci in India: A four-year study

Background & objectives: The incidence and severity of invasive and non-invasive infections demonstrate variability over time. The emerging resistance of Group A streptococci (GAS) to commonly used antibiotics is of grave concern. This study was conducted to assess the antimicrobial resistance of beta-haemolytic streptococci (?HS) in India and to ascertain the molecular mechanisms of resistance. Methods: All isolates of ?HS from the Trauma Centre of All India Institute of Medical Sciences (AIIMS) (north India), and heavily populated area of old Delhi from 2010 to 2014 and Yashoda Hospital, Secunderabad (in south India, 2010-2012) and preserved isolates of ?HS at AIIMS (2005-2009) were included. Phenotypic confirmation was done using conventional methods and the Vitek 2. Antibiotic sensitivity testing was done by disc diffusion and E-test. Detection of resistance genes, erm(A), erm(B), mef(A), tet(M) and tet(O), was done by polymerase chain reaction (PCR). Results: A total of 296 isolates of ?HS (240 from north and 21 from south India) were included in the study. Of the 296 ?HS, 220 (74%) were GAS, 52 (17.5%) were Group G streptococci and 11 (3.7%), 10 (3.3%) and three (1%) were Group B streptococci, Group C streptococci and Group F streptococci, respectively. A total of 102 (46%) and 174 (79%) isolates were resistant to tetracycline and erythromycin, respectively; a lower resistance to ciprofloxacin (21, 9.5%) was observed. A total of 42 (14%) and 30 (10%) isolates, respectively, were positive for tet(M) and erm(B) genes. Only 13 (5%) isolates were positive for mef(A). None of the isolates were positive for erm(A) and tet(O). There was discordance between the results of E-test and PCR for erythromycin and tetracycline. Interpretation & conclusions: A high level of resistance to erythromycin and tetracycline was seen in ?HS in India. Discordance between genotypic and phenotypic results was reported. Absence of erm(A) and tet(O) with high prevalence of tet(M) and erm(B) was observed.

Profi le of fatal Streptococcal bacteraemia at a tertiary care Indian hospital.

Streptococcus pyogenes causes mild to acutely life-threatening diseases. Herein, we report our experience with fi ve cases of fatal bacteraemia due to various groups of Streptococci, three of them due to Group G Streptococcus and one case each due to Group A Streptococcus and Group F Streptococcus. The peculiarity of all these cases was the rapidity of deaths occurring in these patients despite all the strains being sensitive to Penicillin. Hence, timely intervention in all suspected cases is strongly advocated. All isolates of beta-haemolytic Streptococci should be identifi ed up till the species level and antimicrobial susceptibility be performed so that proper and early management can be done.

Effect of intravenous metoclopramide on intraocular pressure: a prospective, randomized, double-blind, placebo-controlled study.

BACKGROUND: Prevention of rise in intraocular pressure (IOP) is essential in patients undergoing surgery for perforated eye injuries. Metoclopramide, a prokinetic agent, is commonly used to hasten gastric emptying in emergency surgeries. AIM: To study the change in IOP after intravenous metoclopramide and to study the influence of metoclopramide on change in IOP after succinylcholine and tracheal intubation. SETTINGS AND DESIGN: A randomized, double-blind, placebo-controlled study of 60 patients undergoing non-ophthalmic elective surgery. MATERIALS AND METHODS: Sixty American Society of Anesthesiologists (ASA) I adult patients were randomly assigned to receive normal saline (Group C) or metoclopramide 10 mg (Group M) 30 min before the induction of anesthesia. Thiopentone was used for induction and succinylcholine for tracheal intubation. Intraocular pressure was measured in both the eyes pre and post drug treatment and succinylcholine and tracheal intubation using Perkins applanation tonometer. STATISTICAL ANALYSIS: Student's t-test and repeated measures ANOVA were used. A P value < 0.05 was considered as significant. RESULTS: Intraocular pressure was consistently lower in Group M than in Group C after the test drug, though the difference was not statistically significant. Intraocular pressure decreased significantly after administration of thiopentone and increased significantly in Groups C and M after tracheal intubation (P<0.01). Intraocular pressure was comparable between the groups at all the times. CONCLUSIONS: Metoclopramide does not cause a clinically significant change in IOP nor does it influence the changes in IOP during anesthesia and tracheal intubation. Metoclopramide shows a trend towards decrease in IOP, though clinically insignificant. Therefore metoclopramide can be used to promote gastric emptying in patients with perforated eye injury.

Neostigmine does not prolong the duration of analgesia produced by caudal bupivacaine in children undergoing urethroplasty.

CONTEXT: Neostigmine extends the duration of analgesia produced by caudal bupivacaine in children. AIMS: To study the effect of different doses of caudal neostigmine on the duration of postoperative analgesia. SETTINGS AND DESIGN: A randomized, double-blind study was conducted in 120 boys aged 1-12 years undergoing urethroplasty under combined general and caudal anesthesia. MATERIALS AND METHODS: Children were administered 1.875 mg/kg bupivacaine alone (Group B) or with 2, 3 or 4 microg/kg of neostigmine (groups BN 2, BN 3 or BN 4 respectively) as caudal drug (0.75 ml/kg). Children with a pain score of 4 or more (OPS and NRS) postoperatively were administered rescue analgesic. Time to first analgesic and the number of analgesic doses administered in the 24h were recorded. STATISTICAL ANALYSIS: Parametric data were analyzed using ANOVA. Kaplan-Meier survival curves for the time to first analgesic administration were plotted and compared using log rank analysis. Chi-square test was used to analyze the incidence data. RESULTS: The median [IQR] time to first analgesic in Group B (540 [240-1441] min) was similar to that in Groups BN 2 (450 [240-720]), BN 3 (600 [360-1020]) and BN 4 (990 [420-1441]). Significantly more patients in Groups B (9 [34.6%]) and BN 4 (13 [44.8%]) required no supplemental analgesic for 24h than those in Groups BN 2 and BN 3 (4 [13.8%] and 4 [13.3%]). The number of analgesic doses required in 24h in the four groups was similar. CONCLUSION: Addition of neostigmine to 1.875 mg/kg of caudal bupivacaine did not prolong the analgesia following urethroplasty in children.

Efficacy and acceptabilty of oral-transmucosal midazolam as a conscious sedation agent in pre-school children.

The purpose of the present study was to test the efficacy of oral-transmucosal route of administration of midazolam in young potentially un-cooperative children. A sample of 40 children up to 4 years of age with ASA I status were randomly divided into experimental and control groups of 20 each. The children in experimental group received 0.5-mg/kg-body weight midazolam mixed in strawberry syrup via the oral-transmucosal route and those in control group were given the same syrup diluted with normal saline. A class II amalgam restoration was performed and routine behavior management techniques were employed in both groups. It was found that the number of procedures successfully completed and sedation produced 15 minutes after test solution administration was significantly greater in the experimental group compared to the control group. The total treatment time was also much lesser in the experimental group children. There was no significant difference in the acceptability of the test solutions in the children of the two groups.

Maternal care receptivity and its relation to perinatal and neonatal mortality. A rural study.

A longitudinal study was conducted on 212 pregnant women from May 1987 to April 1988. Maternal Care Receptivity (MCR) "an innovative approach" was adopted for the assessment of maternal care services provided to pregnant mothers at their door steps. During follow-up, scores were allotted to each of the services rendered and antenatal status of pregnant women. Depending on the score--MCR was classified as high (11 to 8), moderate (7 to 4) or poor (3 to 0). Perinatal and neonatal deaths were recorded and an inverse relationship between MCR and perinatal and mortalities was observed (z = 5.46, p < 0.0001). Significantly, no perinatal or neonatal deaths occurred in women with high MCR. One of the most important cause of high PNMR and neonatal mortality rate in developing countries is poor MCR, i.e., under utilization of even the existing maternal health services. The main reasons for this under utilization appear to be poverty, illiteracy, ignorance and lack of faith in modern medicine.
